This is a non-technical version of "The Decision Problem for Effective Procedures." The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined, even if it does not have a purely mathematical definition—and even if (as many have asserted) for that reason, the Church–Turing thesis (that the effectively calculable functions on natural numbers are exactly the general recursive functions), cannot be proved. However, it is logically provable from the (...) notion of an effective procedure--without reliance on any (partially) mathematical thesis or conjecture concerning effective procedures, such as the Church–Turing thesis--that the class of effective procedures is undecidable, i.e., that no effective procedure is possible for ascertaining whether a given procedure is effective. The proof does not appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of such a procedure. Though this undecidability result itself is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure is, in fact, a decision procedure, i.e., effective—for example, that it invariably terminates with the correct verdict.

The “somewhat vague, intuitive” notion from computability theory of an effective procedure (method) or algorithm can be fairly precisely defined even if it is not sufficiently formal and precise to belong to mathematics proper (in a narrow sense)—and even if (as many have asserted) for that reason the Church–Turing thesis is unprovable. It is proved logically that the class of effective procedures is not decidable, i.e., that no effective procedure is possible for ascertaining whether a (...) given procedure is effective. This undecidability result is proved directly from the notion itself of an effective procedure, without reliance on any (partly) mathematical lemma, conjecture, or thesis invoking recursiveness or Turing-computability. In fact, there is no reliance on anything very mathematical. The proof does not even appeal to a precise definition of ‘effective procedure’. Instead, it relies solely and entirely on a basic grasp of the intuitive notion of an effective procedure. Though the result that effectiveness is undecidable is not surprising, it is also not without significance. It has the consequence, for example, that the solution to a decision problem, if it is to be complete, must be accompanied by a separate argument that the proposed ascertainment procedure invariably terminates with the correct verdict.

This paper develops my (BJPS 2009) criticisms of the philosophical significance of a certain sort of infinitary computational process, a hyperloop. I start by considering whether hyperloops suggest that "effectively computable" is vague (in some sense). I then consider and criticise two arguments by Hogarth, who maintains that hyperloops undermine the very idea of effective computability. I conclude that hyperloops, on their own, cannot threaten the notion of an effective procedure.

This study aimed to identify the effect of procedural justice on organizational loyalty from the point of view of Faculty Staff at Palestine Technical University- Kadoorei. It also aimed to identify the differences in the views of the study sample on the study variables according to the years of service. In order to achieve this, the researchers used a questionnaire consisting of (22) paragraphs where the first area (10) paragraphs looking at procedural justice while the paragraphs of the second area (...) and the number of (12) paragraph in the field of organizational allegiance to Faculty Staff at the university, (105) questionnaires were distributed on the sample of the study, and after the process of distribution of the questionnaire was collected and coded and entered into the computer and processed statistically using the statistical program of social sciences (SPSS). One of the most important findings of the study was that the degree of procedural justice at the heads of departments at Palestine Technical University- Kadoorei, from the point of view of Faculty Staff was between the medium and large, where the average arithmetic (3.65). Respondents also showed a high level of organizational loyalty (3.84). The study also showed a statistically significant effect at the level of significance (α = 0.05) for procedural fairness in achieving organizational loyalty, and the absence of differences attributed to years of experience. In the light of the results of the previous study, the researchers recommended several recommendations, the most important of which is to increase the awareness of the workers on the principles of procedural justice, to encourage adherence to them and to indicate their importance in job performance by creating systems and methods that ensure commitment to justice by raising the ability of leaders to build new policies and visions Which would promote the work of institutions.

The study aimed to identify the role of administrative procedures and systems in enhancing the performance of the educational institutions in the Islamic University in Gaza. To achieve the research objectives, the researchers used the analytical descriptive approach to collect information. The researchers used the questionnaire distributed to three categories of employees at the Islamic University (senior management, faculty members, their assistants and members of the administrative board). A random sample of 314 employees was selected and 276 questionnaires were retrieved (...) with a recovery rate of 88.1%. The Statistical Analysis Program (SPSS) was used to enter process and analyze data. The results of the research showed a positive role for the administrative procedures and systems in enhancing the performance of the Islamic University from the point of view of the members (senior management, teaching staff and their assistants and the administrative body), where the relative weight of all the paragraphs (73.728%). The analysis of the results revealed that the administrative procedures at the Islamic University in Gaza are used to an acceptable degree. The relative weight of all the paragraphs is 70%. This indicates a relationship between administrative procedures and regulations and the performance of the Islamic University in the Gaza Strip. The study found that there was a good degree of approval from the sample regarding the administrative procedures and their relationship to the job performance. There exist a sufficient degree of powers to the deans and department managers to carry out their tasks, with the use of plans as control tools. And that there are rules and procedures provided for decision-making in the University Council. It also has full powers to manage the university to improve the teaching and learning environment. The researchers also recommended a number of recommendations, including the need to follow up on the procedures and systems of management and update them continuously in the light of changes that may occur and to ensure the existence of a strong system of electronic information systems within the university. There is a need to provide mechanisms for obtaining information about the surrounding external environment, and effective mechanisms to provide managers with the necessary information in a timely manner. The importance of providing channels of communication that enables staff to communicate information about any violations and breaches. The study also recommended the follow-up, review, procedures and administrative systems, and work to modify them in line with the mission of the university and the objectives that the university seeks to reach.

"Procedural Justice" offers a theory of procedural fairness for civil dispute resolution. The core idea behind the theory is the procedural legitimacy thesis: participation rights are essential for the legitimacy of adjudicatory procedures. The theory yields two principles of procedural justice: the accuracy principle and the participation principle. The two principles require a system of procedure to aim at accuracy and to afford reasonable rights of participation qualified by a practicability constraint. The Article begins in Part I, Introduction, with (...) two observations. First, the function of procedure is to particularize general substantive norms so that they can guide action. Second, the hard problem of procedural justice corresponds to the following question: How can we regard ourselves as obligated by legitimate authority to comply with a judgment that we believe (or even know) to be in error with respect to the substantive merits? The theory of procedural justice is developed in several stages, beginning with some preliminary questions and problems. The first question - what is procedure? - is the most difficult and requires an extensive answer: Part II, Substance and Procedure, defines the subject of the inquiry by offering a new theory of the distinction between substance and procedure that acknowledges the entanglement of the action-guiding roles of substantive and procedural rules while preserving the distinction between two ideal types of rules. The key to the development of this account of the nature of procedure is a thought experiment, in which we imagine a world with the maximum possible acoustic separation between substance and procedure. Part III, The Foundations of Procedural Justice, lays out the premises of general jurisprudence that ground the theory and answers a series of objections to the notion that the search for a theory of procedural justice is a worthwhile enterprise. Sections II and III set the stage for the more difficult work of constructing a theory of procedural legitimacy. Part IV, Views of Procedural Justice, investigates the theories of procedural fairness found explicitly or implicitly in case law and commentary. After a preliminary inquiry that distinguishes procedural justice from other forms of justice, Part IV focuses on three models or theories. The first, the accuracy model, assumes that the aim of civil dispute resolution is correct application of the law to the facts. The second, the balancing model, assumes that the aim of civil procedure is to strike a fair balance between the costs and benefits of adjudication. The third, the participation model, assumes that the very idea of a correct outcome must be understood as a function of process that guarantees fair and equal participation. Part IV demonstrates that none of these models provides the basis for a fully adequate theory of procedural justice. In Part V, The Value of Participation, the lessons learned from analysis and critique of the three models are then applied to the question whether a right of participation can be justified for reasons that are not reducible to either its effect on the accuracy or its effect on the cost of adjudication. The most important result of Part V is the Participatory Legitimacy Thesis: it is (usually) a condition for the fairness of a procedure that those who are to be finally bound shall have a reasonable opportunity to participate in the proceedings. The central normative thrust of Procedural Justice is developed in Part VI, Principles of Procedural Justice. The first principle, the Participation Principle, stipulates a minimum (and minimal) right of participation, in the form of notice and an opportunity to be heard, that must be satisfied (if feasible) in order for a procedure to be considered fair. The second principle, the Accuracy Principle, specifies the achievement of legally correct outcomes as the criterion for measuring procedural fairness, subject to four provisos, each of which sets out circumstances under which a departure from the goal of accuracy is justified by procedural fairness itself. In Part VII, The Problem of Aggregation, the Participation Principle and the Accuracy Principle are applied to the central problem of contemporary civil procedure - the aggregation of claims in mass litigation. Part VIII offers some concluding observations about the point and significance of Procedural Justice. (shrink)

This chapter begins with an empirical analysis of attitudes towards the law, which, in turn, inspires a philosophical re-examination of the moral status of the rule of law. In Section 2, we empirically analyse relevant survey data from the US. Although the survey, and the completion of our study, preceded the recent anti-police brutality protests sparked by the killing of George Floyd, the relevance of our observations extends to this recent development and its likely reverberations. Consistently with prior studies, we (...) find that people’s ascriptions of legitimacy to the legal system are predicted strongly by their perceptions of the procedural justice and lawfulness of police and court officials’ action. Two factors emerge as significant predictors of people’s compliance with the law: (i) their belief that they have a (content-independent, moral) duty to obey the law (which is one element of legitimacy, as defined here); and (ii) their moral assessment of the content of specific legal requirements (‘perceived moral content of laws’). We also observe an interactive relationship between these two factors. At higher levels of perceived moral content of laws, felt duty to obey is a better predictor of compliance. And, similarly, perceived moral content of laws is a better predictor of compliance at higher levels of felt duty to obey. This suggests that the moral content incorporated in specific laws interacts with the normative force people ascribe to legal authorities by virtue of other qualities, specifically here procedural justice and lawfulness. In Section 3, the focus shifts to a philosophical analysis, whereby we identify a parallel (similarly interactive) modality in the way that form and content mutually affect the value of the rule of law. We advocate a distinctive alternative to two rival approaches in jurisprudential discourse, the first of which claims that Lon Fuller’s eight precepts of legality embody moral qualities not contingent on the law’s content, while the second denies any independent moral value in these eight precepts, viewing them as entirely subservient to the law’s substantive goals. In contrast, on the view put forward here, Fuller’s principles possess (inter alia) an expressive moral quality, but their expressive effect does not materialise in isolation from other, contextual factors. In particular, the extent to which it materialises is partly sensitive to the moral quality of the law’s content. (shrink)

This chapter begins with an empirical analysis of attitudes towards the law, which inspires a philosophical re-examination of the moral status of the rule of law. The chapter analyses survey data from the US about law-related attitudes and legal compliance. Consistently with prior studies, it finds that people’s ascriptions of legitimacy to the legal system are predicted strongly by their perceptions of the procedural justice and lawfulness of police and court officials’ action. Two factors emerge as significant predictors of people’s (...) compliance with the law: (i) their belief that they have a (content-independent, moral) duty to obey the law (which is one element of legitimacy, as defined in the chapter); and (ii) their moral assessment of the content of specific legal requirements (referred to in the chapter as ‘perceived moral content of laws’). The chapter also observes an interactive relationship between these two factors. The authors then identify a parallel (similarly interactive) modality in the way that form and content mutually affect the value of the rule of law. They argue that Lon Fuller’s precepts of legality possess an expressive moral quality, but that the extent to which their expressive effect materialises is sensitive to the moral quality of the law’s content.

Suppose that a patient is receiving treatment options from her doctor. In one case, the doctor says, “the surgery has a 90% survival rate.” Now, suppose the doctor instead said, “the procedure has a 10% mortality rate.” Predictably, the patient is more likely to consent on the first description and more likely to dissent on the second. This is an example of a framing effect. A framing effect occurs when “the description of [logically-equivalent] options in terms of gains (positive (...) frame) rather than losses (negative frame) elicits systematically different choices.” Framing effects are ubiquitous, but they are particularly troublesome in medicine. Many worry that there is tension between valuing informed consent and using framing effects in clinical settings. In this paper, I answer this question: if an individual is subject to a framing effect when she gives her consent, does this undermine the validity of her consent? I argue that framing effects do not undermine consent in general. (shrink)

A violation of procedure invariance in preference measurement is that the predominant or prominent attribute looms larger in choice than in a matching task. In Experiment 1, this so-called prominence effect was demonstrated for choices between pairs of options, choices to accept single options, and preference ratings of single options. That is, in all these response modes the prominent attribute loomed larger than in matching. The results were replicated in Experiment 2, in which subjects chose between or rated their (...) preference for pairs of options which were matched to be equally attractive either in the same session or 1 week earlier. On the basis of these and previous results, it is argued that the prominence effect is a reliable phenomenon. However, none of several cognitive explanations which have been offered appears to be completely viable. (shrink)

This paper takes up the challenge which Carnap poses in his Aufbau: to make of it a basis for continued epistemological research. I try to close some gaps in Carnap’s original presentation and to make at least the first few steps of his constructional outline more accessible to the modern reader. Particularly emphasized is Carnap’s implicit recognition that, to be effective, “structural” models of epistemology (using logical symbols) must be complemented with “procedural” models (his “fictitious operations”). The paper shows (...) how a procedural model, a computer program,can “bypass” Nelson Goodman’s counter example to Carnap’s logical construction of “similarity circles”. (shrink)

Deep Brain Stimulation is currently being investigated as an experimental treatment for patients suffering from treatment-refractory AN, with an increasing number of case reports and small-scale trials published. Although still at an exploratory and experimental stage, initial results have been promising. Despite the risks associated with an invasive neurosurgical procedure and the long-term implantation of a foreign body, DBS has a number of advantageous features for patients with SE-AN. Stimulation can be fine-tuned to the specific needs of the particular (...) patient, is relatively reversible, and the technique also allows for the crucial issue of investigating and comparing the effects of different neural targets. However, at a time when DBS is emerging as a promising investigational treatment modality for AN, lesioning procedures in psychiatry are having a renaissance. Of concern it has been argued that the two kinds of interventions should instead be understood as rivaling, yet “mutually enriching paradigms” despite the fact that lesioning the brain is irreversible and there is no evidence base for an effective target in AN. We argue that lesioning procedures in AN are unethical at this stage of knowledge and seriously problematic for this patient group, for whom self-control is particularly central to wellbeing. They pose a greater risk of major harms that cannot justify ethical equipoise, despite the apparent superiority in reduced short term surgical harms and lower cost. (shrink)

Nostalgia as one of the complex emotions has been challenged over the past few decades due to its psychological and physiological functions. The present experiment investigates the effect of recalling nostalgic memories on amelioration of homeostatic and health state of people with cardiovascular disease. Method: The participants were 30 patients who were hospitalized for angiography procedure. The research was based on an experimental design with randomized and post-test groups. The instruments used included a thermometer with ° C, a checkout (...) manipulation test, a blood pressure monitor, an ice container and a manual timer, a pain intensity perception scale and Batcho’s nostalgia questionnaire. Results: The results showed that there was a significant difference between the two groups in perceived temperature, the resilience in the face of pain, and the perceived pain. The experimental group perceived higher temperature and showed greater resilience in the face of pain and also lower pain intensity was reported. There was no significant difference in blood pressure between the two groups. Conclusion: The results of this study provide significant evidence for the embodiment emotions hypothesis and positive role of Nostalgia in psychological and physiological homeostatic. Further practical implications of results and suggestions for future research were considered. (shrink)

DOI: 10.1080/00031305.2018.1564697 When the editors of Basic and Applied Social Psychology effectively banned the use of null hypothesis significance testing (NHST) from articles published in their journal, it set off a fire-storm of discussions both supporting the decision and defending the utility of NHST in scientific research. At the heart of NHST is the p-value which is the probability of obtaining an effect equal to or more extreme than the one observed in the sample data, given the null hypothesis and (...) other model assumptions. Although this is conceptually different from the probability of the null hypothesis being true, given the sample, p-values nonetheless can provide evidential information, toward making an inference about a parameter. Applying a 10,000-case simulation described in this article, the authors found that p-values’ inferential signals to either reject or not reject a null hypothesis about the mean (α = 0.05) were consistent for almost 70% of the cases with the parameter’s true location for the sampled-from population. Success increases if a hybrid decision criterion, minimum effect size plus p-value (MESP), is used. Here, rejecting the null also requires the difference of the observed statistic from the exact null to be meaningfully large or practically significant, in the researcher’s judgment and experience. The simulation compares performances of several methods: from p-value and/or effect size-based, to confidence-interval based, under various conditions of true location of the mean, test power, and comparative sizes of the meaningful distance and population variability. For any inference procedure that outputs a binary indicator, like flagging whether a p-value is significant, the output of one single experiment is not sufficient evidence for a definitive conclusion. Yet, if a tool like MESP generates a relatively reliable signal and is used knowledgeably as part of a research process, it can provide useful information. (shrink)

Many people in the developing world access essential health services either partially or primarily through programs run by international non-governmental organizations (INGOs). Given that such programs are typically designed and run by Westerners, and funded by Western countries and their citizens, it is not surprising that such programs are regarded by many as vehicles for Western cultural imperialism. In this chapter, I consider this phenomenon as it emerges in the context of development and humanitarian aid programs, particularly those delivering medical (...) treatment, nutrition and access to clean water. I argue that in order to avoid contributing to cultural imperialism, INGOs have a duty to ensure that they do not offer services in a way that requires their beneficiaries to choose between accessing essential health services and violating or otherwise undermining traditional norms and practices which have significance for their beneficiaries. Following Onora O'Neill, I argue that offers requiring such a choice are effectively “unrefuseable” and so coercive. INGOs therefore, must avoid making such offers, and can accomplish this by means of an iterated process of reciprocal negotiation under conditions of equality, in which both the INGOs’ and the beneficiaries’ deep values and concerns play a role. In essence, I claim that employing such a process is a requirement of procedural justice, given the non-ideal conditions in which INGOs must operate. (shrink)

By studying the effect of human resource development on strengthening the firm's total capabilities this literature review investigates the relationship between the development of human capabilities and company performance by studying the effects of human resource development on strengthening a firm’s total capabilities. To provide a thorough grasp of the subject, the review synthesizes and analyzes pertinent research articles, academic papers, and industry reports. SPSS version 22 statistical software was used for social sciences. Descriptive and inferential statistics were used to (...) analyze the questionnaire data. To attain a lasting competitive advantage, the assessment also emphasizes the significance of fostering a learning culture, adopting cutting-edge procedures, and putting in place efficient training and development programs. The main findings show that investing in the growth of human capabilities has a favorable impact on the success of the company, especially when those investments are made in conjunction with the growth of the organization's capabilities. Investing in an employee's skill and capability development boosts productivity, enhances innovation, reduces costs, fosters customer loyalty and satisfaction, and provides a company with a competitive advantage.

What does effective poverty relief entail? How are we to assess the capacity of advanced industrialized societies to solve the problem of poverty? What role, if any, is left for the welfare state? This chapter argues that poverty relief, far from being primarily a matter of post hoc redistribution, primarily consists in a Hayekian-Schumpeterian discovery (or innovation) procedure whereby the problems of the poor are continuously discovered, identified, and eventually solved from the bottom up. This suggests new avenues (...) for reform. I argue, from the point of view of complexity theory, that governments must overcome knowledge and governance problems that limit their competence in the realm of solving the problems of the poor. As a result, any efficient system of poverty relief is unlikely to emerge from imposing an efficient and equitable top-down delivery of given goods and services based on established practices or preferences. The knowledge of what goods and services are required, and what practices should be modified to produce them, is not given to policy makers; it needs to be discovered. And this discovery is best modeled as an entrepreneurial, inquisitive, and experimental process. This process is best understood by applying complexity theory and the Austrian (Hayekian) epistemic paradigm. (shrink)

Clinical psychology is characterized by persistent disagreement about fundamental aspects of the discipline ranging from what mental disorders are to what constitutes effective treatment. Attempts to address the problem of epistemic disagreement have been frequently based on establishing the correct answer by fiat without identifying and addressing the sources of the disagreement. We argue that this strategy has not worked very well and the result is frequently ongoing and intractable disagreement, with each side in an argument convinced they are (...) correct. In this paper, we outline an epistemic disagreement procedural model intended to assist researchers and clinicians in the field of clinical psychology to identify, explore, and develop inquiry strategies that capitalize on situations where competing knowledge claims are made. The result is a flexible conceptual framework committed to a defensible epistemic pluralism, fallibilism, and contextualism, across the various research tasks constituting the field of clinical psychology.

The groundwork has long been laid, by feminist and critical race theorists, for recognizing that a robust social epistemology must be centrally concerned with questions of epistemic injustice; it must provide an account of how inequitable social relations inflect what counts as knowledge and who is recognized as a credible knower.

In their different ways, each contributor is concerned both (...) to understand how dominant epistemic norms perpetuate ignorance and injustice and to articulate effective strategies for redressing these inequities.

The assumption that procuring more organs will save more lives has inspired increasingly forceful calls to increase organ procurement. This project, in contrast, directly questions the premise that more organ transplantation means more lives saved. Its argument begins with the fact that resources are limited and medical procedures have opportunity costs. Because many other lifesaving interventions are more cost‐effective than transplantation and compete with transplantation for a limited budget, spending on organ transplantation consumes resources that could have been used (...) to save a greater number of other lives. This argument has not yet been advanced in debates over expanded procurement and could buttress existing concerns about expanded procurement. To support this argument, I review existing empirical data on the cost‐effectiveness of transplantation and compare them to data on interventions for other illnesses. These data should motivate utilitarians and others whose primary goal is maximizing population‐wide health benefits to doubt the merits of expanding organ procurement. I then consider two major objections: one makes the case that transplant candidates have a special claim to medical resources, and the other challenges the use of cost‐effectiveness to set priorities. I argue that there is no reason to conclude that transplant candidates’ medical interests should receive special priority, and that giving some consideration to cost‐effectiveness in priority setting requires neither sweeping changes to overall health priorities nor the adoption of any specific, controversial metric for assessing cost‐effectiveness. Before searching for more organs, we should first ensure the provision of cost‐effective care. (shrink)

This paper introduces a conceptual framework, denoted as ‘Line Theory,’ which is predicated on the procedural anatomy inherent in ordinary plans. A plan, recognized as a set of instructions for execution, undergoes in-depth scrutiny to analyze its constituent elements. The concise examination delves into the formation of line and effect within real space stemming from procedures. Line theory serves the purpose of elucidating the absolute optimization of plans. It is formulated to inaugurate an exploration into the veracity of procedures and (...) their elemental changes, examining their correlation with space and motion at the most fundamental level. The scientific community has extensively delved into the examination of the behavior and structure of objects at the microscopic level. This paper endeavors to stimulate interest in the analogous analysis of procedures. The fundamental objective within this theoretical framework is to offer a distinct philosophical perspective on changes and effects. (shrink)

Background Neuroimaging and lesion studies suggested that the dorsolateral prefrontal and posterior parietal cortices mediate visual metacognitive awareness. The causal evidence provided by non-invasive brain stimulation, however, is inconsistent. -/- Objective/hypothesis Here we revisit a major figure discrimination experiment adding a new Kanizsa figure task trying to resolve whether bilateral continuous theta-burst transcranial magnetic stimulation (cTBS) over these regions affects perceptual metacognition. Specifically, we tested whether subjective visibility ratings and/or metacognitive efficiency are lower when cTBS is applied to these two (...) regions in comparison to an active control region. -/- Methods A within-subjects design including three sessions spaced by one-week intervals was implemented. In each session, every participant was administered bilateral cTBS to either prefrontal, control or parietal cortices. Two concurrent tasks were performed, a real and an illusory figure task, stabilising objective performance with use of an adaptive staircase procedure. -/- Results When performing the replicated task, cTBS was found insufficient to disrupt neither visibility ratings nor metacognitive efficiency. However, with use of Kanizsa style illusory figures, cTBS over the dorsolateral prefrontal, but not over the posterior parietal cortex, was observed to significantly diminish metacognitive efficiency. -/- Conclusion(s) Real and illusory figure tasks demonstrated different cTBS effects. A possible explanation is the involvement of the prefrontal cortex in the creation of expectations, which is necessary for efficient metacognition. Failure to replicate previous findings for the real figure task, however, cannot be said to support, conclusively, the notion that these brain regions have a causal role in metacognitive awareness. This inconsistent finding may result from certain limitations of our study, thereby suggesting the need for yet further investigation. (shrink)

This paper offers a new angle on the common idea that the process of science does not support epistemic diversity. Under minimal assumptions on the nature of journal editing, we prove that editorial procedures, even when impartial in themselves, disadvantage less prominent research programs. This purely statistical bias in article selection further skews existing differences in the success rate and hence attractiveness of research programs, and exacerbates the reputation difference between the programs. After a discussion of the modeling assumptions, the (...) paper ends with a number of recommendations that may help promote scientific diversity through editorial decision making. (shrink)

In psychophysical experiments, the use of a psychophysical procedure of brightness/darkness cancellation shed light on interactions between spatial arrangement and figure–ground contrast in the perceptual filling in of achromatic and colored surfaces.Achromatic and chromatic Kanizsa squares with varying contrast, contrast polarity, and inducer spacingwere used to test how these factors interact in the perceptual filling in of surface brightness or darkness. The results suggest that the neuronal processing of surfaces with apparent contrast, leading to figure–ground segregation (i.e., perceptual organization), (...) is governed by mechanisms that integrate both luminance contrast and spatial information carried by the inducing stimuli, while discarding information on contrast polarity or color. The findings are discussed in relation to earlier observations on brightness assimilation and contrast. They support theories of nonantagonistic neural mechanisms suppressing local contrast or color signs in brightnessbased figure–ground percepts. Such mechanismsmight be necessary to cancel potentially conflicting polarities in geometricallycomplex visual stimuli so that perceptual filling in resulting in the most plausible representation of figure and ground can be achieved.

The study examined disciplinary management in public primary schools and teachers' job effectiveness in Yakurr Local Government Area, Cross River State. Three null hypotheses were formulated accordingly to guide the study. The study adopted a descriptive survey research design. Census technique was adopted in selecting the entire population of 98 primary school managers which comprised of 49 head teachers and 49 deputy head teachers across 49 public primary schools available in the area.

Schools and Teachers' Job Effectiveness Questionnaire (DCPPSTJEQ)" designed and administered by the researcher was used as an instrument for data collection. The null hypotheses were all tested at .05 level of significance using Pearson Product Moment Correlation Analysis. Findings from the study revealed that warning, suspension, and dismissal have significant relationships respectively, to primary school teachers' job effectiveness. Based on the findings of this study, it was recommended among others that; there should be fairness in the administration of suspension to all teachers through well- documented procedures. (shrink)

Purpose. An empirical verification of the Hemingway’s “sad hypothesis” and study of some individual characteristics of a discourse formation in a process of short texts understanding. -/- Methods and procedure of research. The study was based on the principle of a standardized interview, which was carried out on a random sample (103 respondents) using the questionnaire. The subjects interpreted two proverbs and the short story by Hemingway (“For sale: baby shoes, never worn”). In each case, it was proposed to (...) choose one of the six ready-made interpretations or to create an original one. Proverb explications were classified by experts as “normative” or “deviating”, and interpretations of the story were evaluated into “sad” or “pragmatic” ones. Also, a “normativity index” was calculated for each respondent, reflecting the number of normative renditions of proverbs. The Psychogeometric test was used, and such socio-demographic characteristics were recorded as: gender, age, having children. -/- Results. This study refutes the “sad hypothesis” regarding Hemingway’s six-word story affect. The prevalence of pragmatic type interpretation over sentimental one is statistically significant. The type of interpretation turned out to be not directly related to any of the considered socio-demographic characteristics. It was found that the sad interpretation of the story reliably corresponds to a high normativity of the proverbs explications. Conversely, respondents with deviating interpretations of proverbs were significantly more likely to interpret Hemingway’s story in a pragmatic way. Differential psychological features, which were distinguished using the Psychogeometric test, turned out to be an insignificant predictor of the six-word story interpretations. -/- Conclusions. The analysis of the research results made it possible to argue the thesis that the differences in the formation of individual discourses are directly related to a worldview and indirectly determined by other factors in turn influencing the outlook. The interaction of the worldview with discursive practice that arises in the process of short texts understanding is carried out according to differential scenarios. These scenarios are conditioned by such individual characteristics as discursive conformity and discursive lability, which, in turn, correspond with high and low normativity, respectively. Above features are cognitive in nature. Their ontological localization coincides with the I-language (Chomsky). (shrink)

The fine-tuning argument can be used to support the Many Universe hypothesis. The Inverse Gambler’s Fallacy objection seeks to undercut the support for the Many Universe hypothesis.

Comprehensive High School in Palawan during the months of June to October 2016, completed open-ended questionnaires and took part in the interview. NVivo software was used in the analysis of the themes that emerged from the data. This study discovered that friendship is manipulated, for it makes doing right things unacceptable and things to be avoided like cheating seem right and acceptable. The behavior about cheating during examination is deeply rooted in the culture of pakikisama (social acceptance/liking) and utang ng loob (debt of gratitude). If a learner does not share his or her answers, he or she will be labeled as walang pakisama (no concern).This paper then argues that honesty should not be just a policy; rather, honesty in this case, is the only policy. Condemning academic dishonesty must not merely rest in the enrollment forms, but by constant moral reminder and intervention of teachers who have a responsibility to hone learners' decorum on honesty and maturity.

This dissertation examines aspects of the interplay between computing and scientific practice. The appropriate foundational framework for such an endeavour is rather real computability than the classical computability theory. This is so because physical sciences, engineering, and applied mathematics mostly employ functions defined in continuous domains. But, contrary to the case of computation over natural numbers, there is no universally accepted framework for real computation; rather, there are two incompatible approaches --computable analysis and BSS model--, both claiming to formalise algorithmic (...) computation and to offer foundations for scientific computing. -/- The dissertation consists of three parts. In the first part, we examine what notion of 'algorithmic computation' underlies each approach and how it is respectively formalised. It is argued that the very existence of the two rival frameworks indicates that 'algorithm' is not one unique concept in mathematics, but it is used in more than one way. We test this hypothesis for consistency with mathematical practice as well as with key foundational works that aim to define the term. As a result, new connections between certain subfields of mathematics and computer science are drawn, and a distinction between 'algorithms' and 'effective procedures' is proposed. -/- In the second part, we focus on the second goal of the two rival approaches to real computation; namely, to provide foundations for scientific computing. We examine both frameworks in detail, what idealisations they employ, and how they relate to floating-point arithmetic systems used in real computers. We explore limitations and advantages of both frameworks, and answer questions about which one is preferable for computational modelling and which one for addressing general computability issues. -/- In the third part, analog computing and its relation to analogue (physical) modelling in science are investigated. Based on some paradigmatic cases of the former, a certain view about the nature of computation is defended, and the indispensable role of representation in it is emphasized and accounted for. We also propose a novel account of the distinction between analog and digital computation and, based on it, we compare analog computational modelling to physical modelling. It is concluded that the two practices, despite their apparent similarities, are orthogonal. (shrink)

This article offers an explanation of perhaps Wittgenstein’s strangest and least intuitive thesis – the semantical mutation thesis – according to which one can never answer a mathematical conjecture because the new proof alters the very meanings of the terms involved in the original question. Instead of basing our justification on the distinction between mere calculation and proofs of isolated propositions, characteristic of Wittgenstein’s intermediary period, we generalize it to include conjectures involving effective procedures as well.

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

Simple regression (regression analysis with a single explanatory variable), and multiple regression (regression models with multiple explanatory variables), typically correspond to very different biological questions. The former use regression lines to describe univariate associations. The latter describe the partial, or direct, effects of multiple variables, conditioned on one another. We suspect that the superficial similarity of simple and multiple regression leads to confusion in their interpretation. A clear understanding of these methods is essential, as they underlie a large range of (...) procedures in common use in biology. Beyond simple and multiple regression in their most basic forms, understanding the key principles of these procedures is critical to understanding, and properly applying, many methods, such as mixed models, generalised models, and causal inference using graphs (including path analysis and its extensions). A simple, but careful, look at the distinction between these two analyses is valuable in its own right, and can also be used to clarify widely-held misconceptions about collinearity (correlations among explanatory variables). There is no general sense in which collinearity is a problem. We suspect that the perception of collinearity as a hindrance to analysis stems from misconceptions about interpretation of multiple regression models, and so we pursue discussions about these misconceptions in this light. In particular, collinearity causes multiple regression coefficients to be less precisely estimated than corresponding simple regression coefficients. This should not be interpreted as a problem, as it is perfectly natural that direct effects should be harder to characterise than univariate associations. Purported solutions to the perceived problems of collinearity are detrimental to most biological analyses. (shrink)

Academia is a competitive environment. Early Career Researchers (ECRs) are limited in experience and resources and especially need achievements to secure and expand their careers. To help with these issues, this book offers a new approach for conducting research using the combination of mindsponge innovative thinking and Bayesian analytics. This is not just another analytics book. 1. A new perspective on psychological processes: Mindsponge is a novel approach for examining the human mind’s information processing mechanism. This conceptual framework is used (...) to construct models in studies. The framework is highly flexible and widely applicable for many different types of information processes. The mindsponge approach can help researchers discover interesting ideas or even formulate their very own theories when investigating psychosocial phenomena. This approach brings a fresh wind to the current landscape of social sciences and humanities (SSH). 2. Easy-to-follow analysis protocol: The Bayesian Mindsponge Framework (BMF analytics) is useful in terms of computing and visualizing power but also easy to learn and apply. Contrary to being intimidating, the Bayesian analytics section of this book is presented in a reader-friendly manner with a detailed yet clear step-by-step procedure. Examples are from published BMF articles, allowing readers to immediately practice the method and quickly create their own applications. With educational purposes in mind, the book is very suitable for ECRs who are looking to innovate their research methods. 3. Advocating for low-cost, high-quality research: Doing science can be very costly. Mindsponge innovative thinking and BMF analytics help produce impactful studies using openly available data on online repositories. This is based on the authors’ previous works and experiences. The book presents examples of employing the open R package bayesvl on secondary data from different sources. With less financial constraints, researchers can have more freedom of thought to pursue their curiosity and creativity. ECRs in low- and middle-income countries may find this aspect crucial in their careers. 4. Support and collaboration: The authors share their insights from experiences in the academic publishing system to help readers get through the processes of manuscript writing and peer-reviewing more easily. The authors are also ready to support other researchers with further inquiries and collaboration opportunities at the following website, mindsponge(dot)info. This book is for: a) ECRs whose only abundant resources are their innovation capacity and strength of will; b) Researchers in SSH who want to explore a novel approach to thinking and study conducting; c) Low- and middle-income countries’ researchers looking for a cost-effective research protocol; and, d) Innovative thinkers who want to turn their interesting thoughts into good publications.

What is the correct procedure for determining the contents of perception? Philosophers tackling this question increasingly rely on empirically-oriented procedures in order to reach an answer. I argue that this constitutes an improvement over the armchair methodology constitutive of phenomenal contrast cases, but that there is a crucial respect in which current empirical procedures remain limited: they are unimodal in nature, wrongly treating the senses as isolatable faculties. I thus have two aims: first, to motivate a reorientation of the (...) admissible contents debate into a multimodal framework, charting its various significances. The second is to explore whether any experimental studies of multimodal perception support a so-called Liberal (or ‘high-level’ or ‘rich’) account of perception’s admissible contents. I conclude that the McGurk effect and the ventriloquist effect are both explicable without the postulation of high-level content, but that at least one multimodal experimental paradigm may necessitate such content: the rubber hand illusion. One upshot of this argument is that Conservatives who claim that the Liberal view intolerably broadens the scope of perceptual illusions, particularly from the perspective of perceptual psychology, should pursue other arguments against that view.

A framing effect occurs when an agent's choices are not invariant under changes in the way a decision problem is presented, e.g. changes in the way options are described (violation of description invariance) or preferences are elicited (violation of procedure invariance). Here we identify those rationality violations that underlie framing effects. We attribute to the agent a sequential decision process in which a “target” proposition and several “background” propositions are considered. We suggest that the agent exhibits a framing effect (...) if and only if two conditions are met. First, different presentations of the decision problem lead the agent to consider the propositions in a different order (the empirical condition). Second, different such “decision paths” lead to different decisions on the target proposition (the logical condition). The second condition holds when the agent's initial dispositions on the propositions are “implicitly inconsistent,” which may be caused by violations of “deductive closure.” Our account is consistent with some observations made by psychologists and provides a unified framework for explaining violations of description and procedure invariance.

Much public policy analysis requires us to place a monetary value on the bad- ness of a premature human death. Currently dominant approaches to determining this ‘value of a life’ focus exclusively on the ‘self-regarding’ value of life — that is, the value of a person’s life to the person whose death is in question — and altogether ignore effects on other people. This procedure would be justified if, as seems intuitively plausible, other-regarding effects were negligible in comparison with (...) self-regarding ones. I argue that in the light of the issue of overpopulation, that intuitively plausible condition is at best highly questionable. Unless the world is in fact underpopulated, the social disvalue of a premature death is likely to be significantly lower than the current estimates. (shrink)

Automatic detection of diseases and anatomical landmarks in medical images by the use of computers is important and considered a challenging process that could help medical diagnosis and reduce the cost and time of investigational procedures and refine health care systems all over the world. Recently, gastrointestinal (GI) tract disease diagnosis through endoscopic image classification is an active research area in the biomedical field. Several GI tract disease classification methods based on image processing and machine learning techniques have been proposed (...) by diverse research groups in the recent past. However, yet effective and comprehensive deep ensemble neural network-based classification model with high accuracy classification results is not available in the literature. In this thesis, we review ways and mechanisms to use deep learning techniques to research on multi-disease computer-aided detection about gastrointestinal and identify these images. We re-trained five state-of-the-art neural network architectures, VGG16, ResNet, MobileNet, Inception-v3, and Xception on the Kvasir dataset to classify eight categories that include an anatomical landmark (pylorus, z-line, cecum), a diseased state (esophagitis, ulcerative colitis, polyps), or a medical procedure (dyed lifted polyps, dyed resection margins) in the Gastrointestinal Tract. Our models have showed results with a promising accuracy which is a remarkable performance with respect to the state-of-the-art approaches. The resulting accuracies achieved using VGG, ResNet, MobileNet, Inception-v3, and Xception were 98.3%, 92.3%, 97.6%, 90% and 98.2%, respectively. As it appears, the most accurate result has been achieved when retraining VGG16 and Xception neural networks with accuracy reache to 98% due to its high performance on training on ImageNet dataset and internal structure that support classification problems.

Criminal law practices in the US, including policing and incarceration, have drawn heavy criticism for their disproportionate impact on black people, particularly black men. At the same time, some feminist scholars and activists advocate for increases in criminal law responses to sexual assault, including expanding criminal statutes to cover more instances of sexual assault and increasing sentencing guidelines. These reforms are often justified by claims that criminal law should express more feminist values and reject sexist social schemas. This paper makes (...) the case that criminal legal interventions aimed at changing sexist social schemas, such as ‘rape culture,’ are unlikely to be successful because criminal law is effective at maintaining existing social norms, but bad at introducing novel ones. Similarly, in the US, criminality has been ideologically linked to blackness, so attempts to use the stigma of criminality to combat sexual violence are likely to reinforce anti-black racism. The very meaning of a criminal law depends on related social schemas, and the racist social schemas associated with criminality undermine the ability of criminal legal responses to present anti-sexist values. At best, criminal legal reforms aimed at expressing the equal dignity of women will be ambiguous because their meaning is negotiated by existing sexist and racist social schemas. Thus, penal expressivism cannot offer a justification for using criminal law to combat sexual assault. (shrink)

The issue of common method variance and bias in Indonesia still has not gained much attention; even the terminology is less popular, except among psychometric enthusiasts and experts. In fact, the potential for common method variance and bias infiltrating in research results is very high, especially in studies that use a single method, a single source, and concurrent design, which are highly favored by psychological lecturers and researchers in Indonesia. This paper is a critical review, exposing the debate and serious (...) impact regarding common method variance and bias, as well as procedures for detecting, addressing and correcting its effects. The author hoped this paper contributes in filling the gap in the literature, especially in Psychology Research Methodology text books in the Indonesian language, so that psychological researches in Indonesia continue to increase their quality and to have their better place in international publications.

: This article critically examines the constitution of impairment in prenatal testing and screening practices and various discourses that surround these technologies. While technologies to test and screen prenatally are claimed to enhance women's capacity to be self-determining, make informed reproductive choices, and, in effect, wrest control of their bodies from a patriarchal medical establishment, I contend that this emerging relation between pregnant women and reproductive technologies is a new strategy of a form of power that began to emerge in (...) the late eighteenth century. Indeed, my argument is that the constitution of prenatal impairment, by and through these practices and procedures, is a widening form of modern government that increasingly limits the field of possible conduct in response to pregnancy. Hence, the government of impairment in utero is inextricably intertwined with the government of the maternal body. (shrink)

In an article previously published in this Journal, Anthony Oyowe critically engages with my attempt to demonstrate how the human rights characteristic of South Africa’s Constitution can be grounded on a certain interpretation of Afro-communitarian values that are often associated with talk of ‘ubuntu’. Drawing on recurrent themes of human dignity and communal relationships in the sub-Saharan tradition, I have advanced a moral-philosophical principle that I argue entails and plausibly explains a wide array of individual rights to civil liberties, political (...) power, criminal procedures and economic resources. Oyowe’s most important criticism of my theory is in effect that it is caught in a dilemma: either the principle I articulate can account for human rights, in which case it does not count as communitarian, or it does count as the latter, but cannot account for the former. In this article, I reply to Oyowe, contending that he misinterprets key facets of my theory to the point of not yet engaging with its core strategy for deriving human rights from salient elements of ubuntu. I conclude that Oyowe is unjustified in claiming that there are ‘theoretical lapses’ that ‘cast enormous doubts’ on my project of deriving human rights from a basic moral principle with a recognizably sub-Saharan and communitarian pedigree.

Advancements in machine learning have fuelled the popularity of using AI decision algorithms in procedures such as bail hearings, medical diagnoses and recruitment. Academic articles, policy texts, and popularizing books alike warn that such algorithms tend to be opaque: they do not provide explanations for their outcomes. Building on a causal account of transparency and opacity as well as recent work on the value of causal explanation, I formulate a moral concern for opaque algorithms that is yet to receive a (...) systematic treatment in the literature: when such algorithms are used in life-changing decisions, they can obstruct us from effectively shaping our lives according to our goals and preferences, thus undermining our autonomy. I argue that this concern deserves closer attention as it furnishes the call for transparency in algorithmic decision-making with both new tools and new challenges. (shrink)

In a gradually more interlinked world, the formation of collaborations with partners is increasingly regarded as an important driver for generating innovation. Although multidimensional proximities are important factors influencing interorganizational coinnovation performance, relevant empirical studies have not reached consistent conclusions. By focusing on organizational dyad and including intraorganizational collaboration network inefficiency as a moderating variable, we explore the effects of multidimensional proximities on interorganizational coinnovation performance. By reference to 5G patent data collected in China between 2011 and 2020, the research (...) results based on the quadratic assignment procedure (QAP) model show that geographical proximity, cognitive proximity, and institutional proximity all improve interorganizational coinnovation performance.

Abstract: The study aimed to identify the procedures and speed of response and their role in improving the creative behavior of Palestinian NGOs. The study used the descriptive analytical approach and the questionnaire as a main tool for collecting data from employees of associations operating in Gaza Strip governorates, and the cluster sample method was used and the sample size reached (343) individuals. (298) questionnaires were retrieved, and the following results were reached: The relative weight of the field of taking (...) measures reached (77.33%), and the relative weight of the field of response speed reached (78.66%) and the relative weight of the creative behavior was 78.99 (%), and the results also showed a relationship Statistically significant of me For adopting the procedures and speed of response and creative behavior, and the presence of the effect for adopting procedures and speed of response to the creative behavior, and there are differences statistically significant in scale dimensions due to the variable gender in (response speed, take action) and the differences in favor of females. There were no statistically significant differences attributable to the variable of the age group and the educational qualification, and there were no statistically significant differences in the creative behavior according to the variable of gender, age group, educational qualification, specialization, and the study presented a set of recommendations the most important of them: the necessity of civil organizations in Gaza Strip to obtain Funding from foreign countries in order to provide associations with self-income to face crises and give them independence in order to preserve them in order to play their role in society. The necessity of holding meetings and workshops with the local community, and this helps them determine the needs of society. (shrink)

Researchers often lack the necessary data to credibly estimate racial discrimination in policing. In particular, police administrative records lack information on civilians police observe but do not investigate. In this article, we show that if police racially discriminate when choosing whom to investigate, analyses using administrative records to estimate racial discrimination in police behavior are statistically biased, and many quantities of interest are unidentified—even among investigated individuals—absent strong and untestable assumptions. Using principal stratification in a causal mediation framework, we derive (...) the exact form of the statistical bias that results from traditional estimation. We develop a bias-correction procedure and nonparametric sharp bounds for race effects, replicate published findings, and show the traditional estimator can severely underestimate levels of racially biased policing or mask discrimination entirely. We conclude by outlining a general and feasible design for future studies that is robust to this inferential snare. (shrink)
