Can one’s belief that one romantically loves another be false? If so, under what conditions may one come to reasonably doubt, or at least suspend belief, that one does so? To begin to answer these questions, I first outline an affective/volitional view of love similar to psychologist R. J. Sternberg’s “triangular theory”, which analyzes types of love in terms of the degrees to which they include states of passion, emotion, and commitment. I then outline two sources of potential bias that (...) may cause one to believe that one romantically loves another when one does not. Partly on the basis of those potential sources of bias and partly on the basis of more specific issues, I then argue that at least to the extent that one is aware of these issues, one may reasonably doubt that one is experiencing romantic love’s emotional feelings, and one may reasonably doubt that one is making romantic love’s commitments. Finally, I order by relative dubitability the propositions that must be true about one’s passions, emotions, and commitments toward another in order for one to romantically love them. (shrink)

Abstract: Potatoes are edible tubers, available worldwide and all year long. They are relatively cheap to grow, rich in nutrients, and they can make a delicious treat. The humble potato has fallen in popularity in recent years, due to the interest in low-carb foods. However, the fiber, vitamins, minerals, and phytochemicals it provides can help ward off disease and benefit human health. They are an important staple food in many countries around the world. There are an estimated 200 varieties of (...) potatoes, which can be classified into a number of categories based on the cooked texture and ingredient functionality. Using a public dataset of 2400 images of potatoes, we trained a deep convolutional neural network to identify 4 types (Red, Red Washed, Sweet, and White).The trained model achieved an accuracy of 99.5% of test set, demonstrating the feasibility of this approach.

The question I want to explore is whether experience supports an antireductionist ontology of time, that is, whether we should take it to support an ontology that includes a primitive, monadic property of nowness responsible for the special feel of events in the present, and a relation of passage that events instantiate in virtue of literally passing from the future, to the present, and then into the past.

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

Public health care interventions—regarding vaccination, obesity, and HIV, for example—standardly take the form of information dissemination across a community. But information networks can vary importantly between different ethnic communities, as can levels of trust in information from different sources. We use data from the Greater Pittsburgh Random Household Health Survey to construct models of information networks for White and Black communities--models which reflect the degree of information contact between individuals, with degrees of trust in information from various sources correlated with (...) positions in that social network. With simple assumptions regarding belief change and social reinforcement, we use those modeled networks to build dynamic agent-based models of how information can be expected to flow and how beliefs can be expected to change across each community. With contrasting information from governmental and religious sources, the results show importantly different dynamic patterns of belief polarization within the two communities. (shrink)

Background: In prevalence studies of sexually transmitted infections (STIs), investigators often provide syndromic management for symptomatic participants, but may not provide specific treatment for asymptomatic individuals with positive laboratory test results due to the delays between sample collection and availability of results as well as logistical constraints in recontacting study participants. Methods: To characterize the extent of this issue, 80 prevalence studies from the World Health Organization’s Report on global sexually transmitted infection surveillance, 2018, were reviewed. Studies were classified as (...) to whether clinically relevant positive results were returned or if this was not specified. Results: More than half (56%) of the cited studies did not specify if participants were notified of clinically relevant positive STI test results. The percentages were similar for low- and middle-income country populations (57%) and high-income country populations (53%). Conclusions: The absence of documentation of the provision of test results raises the possibility that in some instances, results may not have been communicated, with potential negative effects for participants, their sexual partners, and newborns. From an ethical perspective, clinically relevant results should be returned to study participants and treating clinicians in a timely fashion to ensure appropriate management of identified infections. Study authors should document if they returned test results to study participants and report on numbers lost to follow-up. (shrink)

Abstract: The research also aims at identifying the differences between respondents as attributed to their professional and personal traits of age, gender, educational level, distribution of department, dispute resolution experience and representation party. Researchers adopted mixed data collection methods; quantitative and qualitative. For qualitative, a semi-structured interview was conducted with (9) officials including management, staff unions and expert external mediators. (63) Questionnaires were distributed to a systematic random sample population; (56) were received, with a response rate 88.9%. The results proved (...) that there are no significant differences among respondents attributed to personal and professional traits of age, academic background, gender, department, years’ of experience, educational degree and representation party. The research has presented some recommendations concerning the factors affecting the mediation outcomes of workplace disputes resolution. The recommendations include: Selecting expert mediators to deal with multi-culture groups. Ensuring equal gender representation in working groups, teamwork and committees and encouraging female participation in mediation processes to resolve dispute at work place. Developing the mediation schema in a way that empowers the mediator to increase her/his ability to lead and establish compromise solutions for workplace disputes. (shrink)

Abstract: The aim of the research is to identify the reality of the quality of health services in light of the Corona Pandemic, and in order to achieve the research objectives, the researchers used the descriptive and analytical approach using a comprehensive survey method for the total research community, whose number reached (110) individuals, while (90) were recovered: The level of health service quality is of relative weight (76%). Among the most important recommendations made by the research: Work to pay (...) a health risk premium to all workers in health centers, in addition to paying attention to training and building work teams in various fields to improve the quality of health services provided.

The German word Destruktion was used by Heidegger in the sense that philosophy should destroy some ontological concepts and the everyday meanings of certain words. Tradition allows the transmission of knowledge and sensations of continuity and connection with the past, but it must be critically evaluated so that it does not perpetuate certain prejudices. According to Heidegger, tradition transmits, but it also conceals. Tradition induces self-evidence and prevents us from accessing the origin of concepts. It makes us believe that we (...) do not need to return to that origin. Making tradition transparent dissolves the concealments it has provoked. Here I will apply this idea to the mental and the physical by suggesting that the mind-body problem has inherited occultations that are born in Descartes himself. As a result, what could be a new philosophical framework for the research in consciousness emerges: That as an individual cognitive being I cannot avoid splitting reality into what I am and what I am not, extending then the individual duality to a collective error transmitted culturally.

Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

Newton published his deduction of universal gravity in Principia (first ed., 1687). To establish the universality (the particle-to-particle nature) of gravity, Newton must establish the additivity of mass. I call ‘additivity’ the property a body's quantity of matter has just in case, if gravitational force is proportional to that quantity, the force can be taken to be the sum of forces proportional to each particle's quantity of matter. Newton's argument for additivity is obscure. I analyze and assess manuscript versions of (...) Newton's initial argument within his initial deduction, dating from early 1685. Newton's strategy depends on distinguishing two quantities of matter, which I call ‘active’ and ‘passive’, by how they are measured. These measurement procedures frame conditions on the additivity of each quantity so measured. While Newton has direct evidence for the additivity of passive quantity of matter, he does not for that of the active quantity. Instead, he tries to infer the latter from the former via conceptual analyses of the third law of motion grounded largely on analogies to magnetic attractions. The conditions needed to establish passive additivity frustrate Newton's attempted inference to active additivity. (shrink)

The self can be understood in objective metaphysical terms as a bundle of properties, as a substance, or as some other kind of entity on our metaphysical list of what there is. Such an approach explores the metaphysical nature of the self when regarded from a suitably impersonal, ontological perspective. It explores the nature and structure of the self in objective reality, that is, the nature and structure of the self from without. This is the objective self. I am taking (...) a different approach. In addition to objective reality, which is usually understood and explored from an impersonal, quasi-observational and metaphysically realist perspective, we can also explore the nature and structure of subjective reality. The nature and structure of subjective reality is defined by the nature and structure of first-personal, conscious experience. Subjective reality is as real as objective reality, and a metaphysical realist such as myself can endorse the existence of both kinds of ontology. The mental states that, as experienced from the first-personal or subjective perspective, capture the nature and structure of subjective reality, are included in objective reality. The questions to explore in a subjective ontology of the self concern the nature and structure of the self from the first-personal or subjective perspective, that is, the nature and structure of the self from within. This is the subjective self. (shrink)

We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but (...) do find evidence for a "functional" filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures—and not the fragments themselves—that serve as the basis for rapid recognition. (shrink)

This contribution aims to explore the historical predecessors of the Five Percenter model of self-realization, as popularized by Hip Hop artists such as Supreme Team, Rakim Allah, Brand Nubian, Wu-Tang Clan, or Sunz of Man.

By putting the coded system of the tenfold (...)

Our visual experience of the world is one of diverse objects and events, each with particular colors, shapes, and motions. This experience is so coherent, so immediate, and so effortless that it seems to result from a single system that lets us experience everything in our field of view. But however appealing, this belief is mistaken: there are severe limits on what can be visually experienced. -/- For example, in a display for air-traffic control it is important to track all (...) moving items. For a single item, this can be done without problem. Three or four can also be tracked, although some degree of effort may be needed. As the number is increased further, accurate tracking becomes more and more difficult—and eventually, impossible. Performance is evidently affected by a factor within the observer which enables certain kinds of perception to occur, but is limited in some way. This factor is generally referred to as attention. -/- At various times, attention has been associated with clarity of perception, intensity of perception, consciousness, selection, or the allocation of a limited “resource” enabling various operations (see Hatfield, 1998). During the past several decades, considerable progress has been achieved by focusing on the idea of selection (Broadbent, 1982). In particular, attention can be productively viewed as contingently selective processing. This can be embodied in various ways by various processes—there need not be a single quantity identified with all forms of attention, or a single site where it operates (Allport, 1993; Tsotsos, 2011). Although “paying attention” is often considered to be a unitary operation, it may simply refer to the control of one or more selective processes, ideally in a co-ordinated way. While this view has some cost in terms of conceptual simplicity, it can help make sense of a large set of phenomena. -/- This article surveys several of the major issues in our understanding of attention and how it relates to perception. It focuses on vision, since many—if not all—considerations are similar for all sensory modalities, and the level of understanding achieved in this domain is currently the most advanced. (shrink)

This paper examines a recent, influential argument for individualism in psychology defended by Jerry Fodor and others, what I call the argument from causal powers. I argue that this argument equivocates on the crucial notion of "causal powers", and that this equivocation constitutes a deep problem for arguments of this type. Relational and individualistic taxonomies are incompatible, and it does not seem in general to be possible to factor the former into the latter. The distinction between powers and properties plays (...) a central role in my argument. (shrink)

Home management and controlling have seen a great introduction to network that enabled digital technology, especially in recent decades. For the purpose of home automation, this technique offers an exciting capability to enhance the connectivity of equipment within the home. Also, with the rapid expansion of the Internet, there are potentials that added to the remote control and monitoring of such network-enabled devices. In this paper, we had been designed and implemented a fully manageable and secure smart home automation system (...) based on a cloud computing system with an ESP Arduino system. The security of home had been improved by adding a complete camera system with a GSM communication technique to connect the Arduino output data to an external specified number if there is no internet provider. We used three sensors for temperature, gas, and motion measurements. The ESP8226 Wi-Fi device programmed the sensors to maintain the sensors measurements and transfer them to the cloud server database which is programmed to the web server via Appatshy and Mysql formats. The system implemented with high time response so that all readings updated and appeared spontaneously. The designed system should be effective, a secure, and rapid response real-time smart home system should be achieved. (shrink)

Abstract: This study aimed to analyze the relationship between the determinants of organizational justice and altruistic behavior from the point of view of the police officers in Gaza Strip. The study relied on the descriptive and analytical approach, using the questionnaire, and targeting a stratified random sample of (400) officers, who hold the rank of captain and above, from the study population of 1550 officers, and the study tool was distributed to the sample members in all departments and governorates Police (...) in Gaza Strip. (353) questionnaires were retrieved, with a recovery rate of (88.3%). The study found the existence of a positive correlation between the determinants of organizational justice and altruistic behavior, and the study also found the existence of organizational justice in general in a moderate degree and the order of its determinants was as follows: fairness of dealings and to a large degree, followed by fairness of procedures and a medium degree, and finally, distribution fairness was to a small degree, as for altruistic behavior. It came to a large extent. There are statistically significant differences between the respondents ’average response to the researched relationship due to the variables (Type Of Administration, Age Group, Job Title, Military Rank, and Years of Service).

A suggestion famously made by Peter Winch and carried through to present discussions holds that what constitutes the social as a kind consists of something shared – rules or practices commonly learned, internalized, or otherwise acquired by all members belonging to a society. This essays argues against the explanatory efficacy of appeals to this shared something as constitutive of a social kind by examining a violation of social norms or rules, viz., mistakes. I argue that an asymmetric relation exists between (...) the notion of mistakes and that of the social. In particular, mistakes do not presuppose a concept of the social, but the concept of the social requires prior specification of a category of mistakes. But no such prior specification proves possible. The very notion of a mistake is so inchoate that it makes it impossible to provide the kind of regimentation required for a rule-governed domain. Thus, there may be recognized mistakes even in the absence of a unified system or common knowledge of norms.Later writers attempt to avoid Winch's over-strong assumption that something shared and internal constitutes the social but cannot. Extending recent work by Stephen Turner, I argue that ``the social'' is not a domain that is susceptible to lawlike treatment, but rather a heterogeneous, motley collection. For absent the assumption of a shared something, no social object exists to be explained. So, I conclude, we have at present no clear way of marking out the social as a coherent or unified domain of inquiry. (shrink)

Doctors must now take a fifth vital sign from their patients: pain reports. I use this as a case study to discuss how different schools of psychology (introspectionism, behaviorism, cognitive psychology) have treated verbal reports about the contents of consciousness.

I discuss examples from cognitive (...) psychology, including pain researchers' attempts to develop self-reports of pain so that they can be, like other vital signs, reliable indicators of internal states.

Number systems differ cross-culturally in characteristics like how high counting extends and which number is used as a productive base. Some of this variability can be linked to the way the hand is used in counting. The linkage shows that devices like the hand used as external representations of number have the potential to influence numerical structure and organization, as well as aspects of numerical language. These matters suggest that cross-cultural variability may be, at least in part, a matter of (...) whether devices are used in counting, which ones are used, and how they are used. (shrink)

A heuristic is a rule of thumb. In psychology, heuristics are relatively simple rules for making judgments. A fast heuristic is easy to use and allows one to make judgments quickly. A frugal heuristic relies on a small fraction of the available evidence in making judgments.

Prior scholarly approaches to meaningful work have largely fallen into two camps. One focuses on identifying how work can contribute to a meaningful life. The other studies the antecedents and outcomes of workers experiencing their work as meaningful.

In this paper, I give a new, commitment-based account of meaningful work by focusing on the reasons people have to choose meaningful work over other (...) options. I draw on philosopher Ruth Chang’s account of voluntarist reasons (reasons that arise from an act of the will) to argue that commitments can create distinctive reasons to pursue certain work. It is the presence of these distinctive reasons that makes work meaningful. (shrink)

Note: This is a "pre-review" version, not the final version that will be published. -/- In “Nothing is True,” Will Gamester defends a form of alethic nihilism that still grants truth-talk a kind of legitimacy: an expressive role that is implemented via a pretense. He argues that this view has all of the strengths of deflationism, while also providing an elegant resolution of the Liar Paradox and its kin. For the alethic nihilist, Liar and related sentences are not true, and (...) that is the end of the story. No contradiction arises because it does not thereby follow that any of these sentences are also true, since nothing is. Gamester concludes that the simplicity of this response to the semantic paradoxes makes alethic nihilism an attractive approach. We disagree. In addition to providing insurmountable obstacles for his form of alethic nihilism, we contend that a certain form of non-nihilist deflationism is better placed to deal with the paradoxes and to account for truth-talk more generally.

After reconstructing three arguments for Nietzsche’s descriptive analysis of the self as complex, this article clarifies some of greatness’s psychological conditions. It then offers three arguments for why we should not focus on these internal conditions when seeking to verify or to achieve greatness. First, Nietzsche’s descriptive analysis of the self renders introspection too coarse-grained and error-prone to verify the subtle type of unity required for greatness. Second, Nietzsche associates introspective appraisal of one’s psyche with a moral project that weakens (...) and represses the drives, such that inquiry into whether greatness’s internal conditions are satisfied typically speaks against their realization. Finally, the actions characteristic of Nietzsche’s great individuals prohibit introspective preoccupation with oneself. These arguments suggest that we should attend to outwardly directed accomplishments, rather than psychology, when appraising the greatness of others and seeking to become great ourselves. (shrink)

The first purpose of this series of articles is to introduce case studies on how current AI models can be used in the development of a possible theory of quantum gravity, their limitations, and the role the researcher has in steering the development in the right direction, even highlighting the errors, weaknesses and strengths of the whole process. The second is to introduce the new Presentist Fragmentalist ontology as a framework and use it for developing theories of quantum gravity and (...) speculate on achieving a TOE. We emphasize it is necessary for the researcher to check everything in these articles for themselves. While there are many good ideas in this series of papers, the AI is known to make even arithmetic and algebraic mistakes. To select just five apparently good ideas, there is a causal interaction tensor Cαβγδ(F1, F2) that encodes the causal relationship and the strength of the (possibly non-local) interaction between two fragments of reality (formed by each quantum system). There is a quantitative prediction for a testable table-top experiment. There is an explanation of how spacetime emerges from the fragments and their interactions. There is an explicit account of the double-slit experiment. And there is an explanation how this theory accommodates dark matter and dark energy simultaneously. We explore ideas, equations they lead to, concrete calculations, and give corrections along the way. While these are generally morally right within this framework they must be checked by the researcher. Given this caveat, we believe we have made significant progress with the PF interpretation in developing a theory of quantum gravity and pointing out a possible path to a TOE. (shrink)

Recent scholarship has drawn attention to John Rawls’s concern with stability—a concern that, as Rawls himself notes, motivated Part III of A Theory of Justice and some of the more important changes of his political turn. For Rawls, the possibility of achieving ‘stability for the right reasons’ depends on citizens possessing sufficient moral motivation. I argue, however, that the moral psychology Rawls develops to show how such motivation would be cultivated and sustained does not cohere with his specific descriptions of (...) ‘pluralist ’ doctrines. Considering Rawls’s claims that ‘most’ citizens—both in contemporary liberal democracies and in the well-ordered society—possess such doctrines, this incompatibility threatens to undermine his stability arguments. Despite the enormous importance of pluralist doctrines and the potential difficulties they pose for Rawls’s project, remarkably little attention has been paid to them. By critically examining these difficulties, the article begins to address this oversight. (shrink)

Sorensen (1992) has provided two modal-logical schemas to reconstruct the logical structure of two types of destructive thought experiments: the Necessity Refuter and the Possibility Refuter. The schemas consist of five propositions which Sorensen claims but does not prove to be inconsistent.We show that the five propositions, as presented by Sorensen, are not inconsistent, but by adding a premise (and a logical truth), we prove that the resulting sextet of premises is inconsistent. Häggqvist (2009) has provided a different modal-logical schema (...) (Counterfactual Refuter), which is equivalent to four premises, again claimed to be inconsistent. We show that this schema also is not inconsistent, for similar reasons. Again, we add another premise to achieve inconsistency. The conclusion is that all three modal-logical reconstructions of the arguments that accompany thought experiments, two by Sorensen and one by Häggqvist, have now been made rigorously correct. This may inaugurate new avenues to respond to destructive thought experiments. (shrink)

A reading of Feyerabend in Against Method, and a comparison of C.S. Peirce.

Understanding the autonomic nervous system and homeostatic changes associated with emotions remains a major challenge for neuroscientists and a fundamental prerequisite to treat anxiety, stress, and emotional disorders. Based on recent publications, the inter-relationship between respiration and emotions and the influence of respiration on autonomic changes, and subsequent widespread membrane potential changes resulting from changes in homeostasis are discussed. We hypothesize that reversing homeostatic alterations with meditation and breathing techniques rather than targeting neurotransmitters with medication may be a superior method (...) to address the whole body changes that occur in stress, anxiety, and depression. Detrimental effects of stress, negative emotions, and sympathetic dominance of the autonomic nervous system have been shown to be counteracted by different forms of meditation, relaxation, and breathing techniques. We propose that these breathing techniques could be used as firstline and supplemental treatments for stress, anxiety, depression, and some emotional disorders. (shrink)

For scatterplots with gaussian distributions of dots, the perception of Pearson correlation r can be described by two simple laws: a linear one for discrimination, and a logarithmic one for perceived magnitude (Rensink & Baldridge, 2010). The underlying perceptual mechanisms, however, remain poorly understood. To cast light on these, four different distributions of datapoints were examined. The first had 100 points with equal variance in both dimensions. Consistent with earlier results, just noticeable difference (JND) was a linear function of the (...) distance away from r = 1, and the magnitude of perceived correlation a logarithmic function of this quantity. In addition, these laws were linked, with the intercept of the JND line being the inverse of the bias in perceived magnitude. Three other conditions were also examined: a dot cloud with 25 points, a horizontal compression of the cloud, and a cloud with a uniform distribution of dots. Performance was found to be similar in all conditions. The generality and form of these laws suggest that what underlies correlation perception is not a geometric structure such as the shape of the dot cloud, but the shape of the probability distribution of the dots, likely inferred via a form of ensemble coding. It is suggested that this reflects the ability of observers to perceive the information entropy in an image, with this quantity used as a proxy for Pearson correlation. (shrink)

The question I wish to explore is this: Does idealism conflict with common sense? Unfortunately, the answer I give may seem like a rather banal one: It depends. What do we mean by ‘idealism’ and ‘common sense?’ I distinguish three main varieties of idealism: absolute idealism, Berkeleyan idealism, and dualistic idealism. After clarifying what is meant by common sense, I consider whether our three idealisms run afoul of it. The first does, but the latter two don’t. I conclude that while (...) Moore’s famous common sense critique is sound against external world skepticism, against Berkeleyan idealism and dualist idealism it is unavailing. (shrink)

As observers, we generally have a strong impression of seeing everything in front of us at any moment. But compelling as it is, this impression is false – there are severe limits to what we can consciously experience in everyday life. Much of the evidence for this claim has come from two phenomena: change blindness (CB) and inattentional blindness (IB). -/- CB refers to the failure of an observer to visually experience changes that are easily seen once noticed. This can (...) happen even if the changes are large, constantly repeat, and the observer has been informed that they will occur. A related phenomenon is IB – the failure to visually experience an object or event when attention is directed elsewhere. For example, observers may fail to notice an unexpected object that enters their visual field, even if this object is large, appears for several seconds, and has important consequences for the selection of action. -/- Both phenomena involve a striking failure to report an object or event that is easily seen once noticed. As such, both are highly counterintuitive, not only in the subjective sense that observers have difficulty believing they could fail so badly at seeing but also in the objective sense that these findings challenge many existing ideas about how we see. But as counterintuitive as these phenomena are, progress has been made in understanding them. Indeed, doing so has allowed us to better understand the limitations of human perception in everyday life and to gain new insights into how our visual systems create the picture of the world that we experience each moment our eyes are open.

Four experiments investigated the extent to which abstract quantitative information can be conveyed by basic visual features. This was done by asking observers to estimate and discriminate Pearson correlation in graphical representations where the first data dimension of each element was encoded by its horizontal position, and the second by the value of one of its visual features; perceiving correlation then requires combining the information in the two encodings via a common abstract representation. Four visual features were examined: luminance, color, (...) orientation, and size. All were able to support the perception of correlation. Indeed, despite the strikingly different appearances of the associated stimuli, all gave rise to performance that was much the same: just noticeable difference was a linear function of distance from complete correlation, and estimated correlation a logarithmic function of this distance. Performance differed only in regards to the level of noise in the feature, with these values compatible with estimates of channel capacity encountered in classic experiments on absolute perceptual magnitudes. These results suggest that quantitative information can be conveyed by visual features that are abstracted at relatively low levels of visual processing, with little representation of the original sensory property. It is proposed that this is achieved via an abstract parameter space in which the values in each perceptual dimension are normalized to have the same means and variances, with perceived correlation based on the shape of the joint probability density function of the resultant elements.

En 1968 ocurrieron dos hechos sobre los cuales cabe hacer una reflexión orientada por la bioética: la llamada Revolución del 68 y la aparición de la Carta encíclica Humanae Vitae. El Concilio Vaticano II, que fue presentado como una actualización de la Iglesia católica al mundo moderno, fue el escenario de los estudios previos a la redacción del documento pontificio, donde Pablo VI dejó clara la postura del Magisterio de la Iglesia sobre la moral sexual y anticipa los errores prácticos (...) que se seguirían a planteamientos conceptuales antropológicos erróneos o equivocados sobre esa temática. Hay necesidad de rehabilitar la Humanae vitae para volver a percibir el acto conyugal en su “verdad inalterable”, donde no se puede separar el bien y la belleza de la donación mutua de los cónyuges, que redunda en el bien común de la sociedad para defender su célula básica y nuclear que es la familia. In 1968, two events occurred on which it is worth reflecting on bioethics: the so-called Revolution of 1968 and the appearance of the Encyclical Letter Humanae Vitae. The Second Vatican Council, which was presented as an update of the Catholic Church to the modern world, was the scene of the studies prior to the drafting of the pontifical document, where Paul VI made clear the position of the Magisterium of the Church on sexual morality and it anticipates the practical errors that would follow erroneous or mistaken anthropological conceptual approaches on this subject. There is a need to rehabilitate Humanae vitae in order to re-perceive the conjugal act in its "unalterable truth", where good and beauty cannot be separated from the mutual donation of the spouses, which results in the common good of society to defend its basic and nuclear cell which is the family.

This article challenges the view most recently expounded by Emily Jackson that ‘decisional privacy’ ought to be respected in the realm of artificial reproduction (AR). On this view, it is considered an unjust infringement of individual liberty for the state to interfere with individual or group freedom artificially to produce a child. It is our contention that a proper evaluation of AR and of the relevance of welfare will be sensitive not only to the rights of ‘commissioning parties’ to AR (...) but also to public policy considerations. We argue that AR has implications for the common good, by involving matters of human reproduction, kinship, race, parenthood and identity. In this paper we challenge presuppositions concerning decisional privacy. We examine the essential commodification of human life implicit in AR and the systematicity that makes this possible. We address the objection that it is an ethically neutral way of having children and consider the problem of ‘existential debt’. After examining objections to the thesis that AR is illegitimate for reasons of public policy and the common good, we return to the issue of decisional privacy in the light of considerations concerning the legitimate role of the state in matters affecting human reproduction.

This study examines the relationship between technological profile, digital literacy, and self-efficacy among teachers in blended learning. The study utilized the descriptive-correlational design. The participants involved 35 teachers selected via purposive sampling from urban schools in Maasin City implementing printed and online teaching modalities. Standardized tools assessed teachers’ digital technology profile, literacy, and self-efficacy. Significant findings revealed that teachers have easy access to digital technology, are somewhat familiar with technological concepts, often utilize ICT-based technologies, and perceive usage purposes as necessary. (...) Teachers’ digital literacy and self-efficacy are at the average level. Correlation analysis established a significant and strong relationship between the technological profile of teachers and their digital literacy. Digital literacy also significantly and strongly correlated with self-efficacy. This study concluded that the technological profile of teachers influences their digital literacy level. Teachers with high digital literacy skills increase their self-efficacy in technology integration. The blended learning approach constitutes teachers’ digital literacy and self-efficacy as critical players of effectiveness. (shrink)

The ideas that law is (or can be regarded as) a legal system, and that law evolves over time in adaptation to its context, are two of the most widely shared and presupposed ideas in contemporary legal theory. However, even if much interest has been dedicated in legal theory and legal dogmatics to the evolution of specific legal concepts or institutions, as well as legal norms in particular, not so much attention has been dedicated to the evolution of legal systems (...) in themselves. In this chapter, I will try to offer an overview of the evolution of the concept of legal system and critically analyse whether an evolutionary theory of legal systems - i.e., a theory about the evolution of legal systems - can be reconstructed and laid down for the analysis both of the past, the present, and the future of legal systems.

We describe an evaluation undertaken on contract for the New Zealand State Services Commission of a major project (the Administrative Decision-Making Skills Project) designed to produce a model of administrative decision making and an associated teaching/learning packagefor use by government officers. It describes the evaluation of a philosophical model of decision making and the associated teaching/learning package in the setting of the New Zealand Public Service, where a deliberate attempt has been initiated to improve the quality of decision making, especially (...) in relation to moral factors.

This is the first in a series of papers developing a theory of quantum gravity that is consistent with the PF interpretation of quantum mechanics. "Key Features: Reconciles quantum theory, general relativity, and the PF interpretation in a common framework...".

Focused attention is needed to perceive change (Rensink et al., 1997; Psychological Science, 8: 368-373) . But how much attentional processing is given to an item? And does this depend on the nature of the task? To answer these questions, "flicker" displays were created, where an original and a modified image continually alternated, with brief blanks between them. Each image was an array of simple figures, half being horizontal and the other half vertical. In half the trials, one of the (...) items changed orientation; in the remainder, all items remained the same. Observers were asked to detect whether a change was occurring in each trial. -/- Within-observer comparisons for different shapes of items yielded two classes of speed: relatively fast search (50 ms/item) for simple lines, and slower search (90 ms/item) for compound figures made of two or more lines. Evidently, more processing was given to compound figures, even though shape was irrelevant to the task. A similar set of experiments asked observers to detect changes in contrast polarity. Here, no differences were found for different shapes, indicating that geometric information is not processed as much when the task involves only nongeometric properties. (shrink)
