Du Bois regarded social reform as a legitimate object for the scientist. He gave a place to non-epistemic values in scientific reasoning and, to counter the effects of scientific racism, he constructed his approach around the belief that scientists must adopt an assumption or scientific hypothesis that African Americans are human. His engagement in scientific research was a way to reform the society in which he lived, which in turn, led him to defend the faithfulness to fact as his conception (...) of scientific objectivity. This essay examines his sophisticated theory of facts, account of the difference between the natural and human sciences, and unique pragmatist theory of truth. (shrink)

Nothing was more important for W. E. B. Du Bois than to promote the upward mobility of African Americans. This essay revisits his “The Conversation of Races” to demonstrate its general philosophical importance. Ultimately, Du Bois’s three motivations for giving the address reveal his view of the nature of philosophical inquiry: to critique earlier phenotypic conceptions of race, to show the essentiality of history, and to promote a reflexive practice. Commentators have been unduly invested in the hermeneutic readings and as (...) a result have misunderstood it as a philosophical text. Du Bois did more than introduce the concept of race into the purview of philosophy, he provided a method for philosophical inquiry into a concept that is notoriously difficult to approach with precision. My goal here is to show why no introduction to philosophy and no discussion about the nature of philosophical inquiry is complete without consideration of “Conservation.” Certainly, it is a text about race, but it is also an important philosophical text in general.

This study investigates the relationship between mental health and emotional intelligence among senior high school students in a public school. Thus, the study employed a correlational design to measure the relationship between mental health and emotional intelligence among 152 Grade 12 senior high school students in a public school. Hence, to measure the study’s variables - Mental Health Inventory and Emotional Intelligence Scale (EIS) were utilized. Based on the inferential statistics, the r coefficient of 0.32 indicates a low positive correlation (...) between the variables and a p-value of 0.00, indicating a significant relationship between the respondents' mental health and emotional intelligence. Implications and recommendations were discussed in the study. (shrink)

A reality for many information technology (IT) organizations is the need to hire IT talent from other cities or countries to supplement their employee staff. As organizations extend their software development work to remote locations, however, a distinct productivity gap can emerge between co-located and distributed teams. The problem this study addresses is the reduced productivity levels for teams practicing the Agile methodology when team members are distributed by location or time zone. Specifically, it was unknown if there are organizational (...) factors which can improve the productivity of these distributed development teams. The purpose of this study was to determine whether any amount of separation of team members impacts productivity, or if various degrees of time zone overlap allows for sufficient synchronous communication to overcome the communication lag inherit with having distributed teams. Productivity was measured by the number of story points per cycle day completed by the team. Two additional variables were collected to study the impact of sourcing and task complexity on distributed team productivity. A quantitative data analysis was conducted on a large, globally distributed technology organization practicing the Agile methodology across the Americas, Europe, Africa, Asia, and Australia. Teams were classified in the study based on the amount of time zone overlap of the team members. The results of the study found that teams which were co-located or had any amount of time zone overlap performed at similar levels of productivity, while teams with no overlapping business day experienced significantly lower levels of productivity (p < .05). Conversely, sourcing of the resources either as contractors or employees did not demonstrate a significant difference in team productivity. The data analysis on task complexity showed mixed results; there was a different level of productivity when some teams were working tasks of different complexity, but the data was further nuanced by team member location. This study indicates the importance of resource location as a key factor in team productivity. Further study on organizational design could be beneficial to better understand how organizations should select locations to optimize productivity. (shrink)

ABSTRACT In ‘Scorekeeping in a Pornographic Language Game’, Rae Langton and Caroline West borrow ideas from David Lewis to attempt to explain how pornography might subordinate and silence women. Pornography is supposed to express certain misogynistic claims implicitly, through presupposition, and to convey them indirectly, through accommodation. I argue that the appeal to accommodation cannot do the sort of work Langton and West want it to do: Their case rests upon an overly simplified model of that phenomenon. I argue further (...) that, once we are clear about why Langton and West's account fails, a different and more plausible account of pornography's influence emerges. (shrink)

Rae Langton and Caroline West argue that pornography silences women by presupposing misogynistic attitudes, such as that women enjoy being raped. More precisely, they claim that a somewhat infamous pictorial, ‘Dirty Pool’, makes such presuppositions, and that it is typical in this respect. I argue for four claims. (1) There are empirical reasons to doubt that women are silenced in the way that Langton and West claim they are. (2) There is no evidence that very much pornography makes the sorts (...) of presuppositions that Langton and West's explanation of silencing requires it to make. (3) Even ‘Dirty Pool’, for all its other problems, does not make such presuppositions. (4) Langton and West misread ‘Dirty Pool’ because they do not take proper account of the fact that pornography often traffics in sexual fantasy. The broader lesson is that we need to read pornography more sensitively if we are to understand its capacity to shape socio‐sexual norms (for good or for ill). (shrink)

This paper has three goals. The first is to defend Tristan Taromino and Erika Lust (or some of their films) from criticisms that Rebecca Whisnant and Hans Maes make of them. Toward that end, I will be arguing against the narrow conceptions that Whisnant and Maes have of what `feminist' pornography must be like. More generally, I hope to show by example why it is important to take pornographic films seriously as films if we're to understand their potential to shape, (...) or mis-shape, socio-sexual norms.

What Bar-On and Simmons call 'Conceptual Deflationism' is the thesis that truth is a 'thin' concept in the sense that it is not suited to play any explanatory role in our scientific theorizing. One obvious place it might play such a role is in semantics, so disquotationalists have been widely concerned to argued that 'compositional principles', such as -/- (C) A conjunction is true iff its conjuncts are true -/- are ultimately quite trivial and, more generally, that semantic theorists have (...) misconceived the relation between truth, meaning, and logic. This paper argues, to the contrary, that even such simple compositional principles as (C) have substantial content that cannot be captured by deflationist 'proofs' of them. The key thought is that (C) is supposed, among other things, to affirm the truth-functionality of conjunction and that disquotationalists cannot, ultimately, make sense of truth-functionality. -/- This paper is something of a companion to "The Logical Strength of Compositional Principles".

This is a completely informal presentation of the ideas behind the diagonal lemma. One really can't see this important result from too many different angles. This one aims at getting the main idea across. (For the cognoscenti, it is in the spirit of Quine's treatment in terms of "appended to its own quotation".).

A teaching document I've used in my courses on truth and on incompleteness. Aimed at students who have a good grasp of basic logic, and decent math skills, it attempts to give them the background they need to understand a proper statement of the classic results due to Gödel and Tarski, and sketches their proofs. Topics covered include the notions of language and theory, the basics of formal syntax and arithmetization, formal arithmetic (Q and PA), representability, diagonalization, and the incompleteness (...) and undefinability theorems.

A speculative investigation of how Frege's logical views change between Begriffsschrift and Grundgesetze and how this might have affected the formal development of logicism.

This study examined the effectiveness of video-based instruction (VBI) as a learning remediation strategy in teaching Laws of Thermodynamics among Prospective Science Teachers at Bulacan State University. The researchers employed – a one-group pretest–posttest design to assess the 35 prospective science teachers who were purposively selected. More so, data was gathered through researcher-made pretest-posttest achievement tests and an adapted Likert survey questionnaire. The data was treated descriptively and inferentially. The findings showed that VBI as a learning remediation strategy positively affected (...) the preservice teachers’ achievement. In addition, data shows a significant difference between the pretest and posttest in teaching the laws of thermodynamics. The ease of use of VBI as learning remediation in teaching laws of thermodynamics in terms of pedagogical content, individual learning focus, ability to work at pace, and increased engagement was very effective. The learning achievement of the prospective science teachers was significantly related to the ease of use of VBI as a learning remediation. However, it was observed to have a high positive association. Future use of VBI can enhance the prospective science teacher’s competence in using VBI in teaching science subjects. (shrink)

We attempt here to trace the evolution of Frege’s thought about truth. What most frames the way we approach the problem is a recognition that hardly any of Frege’s most familiar claims about truth appear in his earliest work. We argue that Frege’s mature views about truth emerge from a fundamental re-thinking of the nature of logic instigated, in large part, by a sustained engagement with the work of George Boole and his followers, after the publication of Begriffsschrift and the (...) appearance of critical reviews by members of the Boolean school.

An overview of what Frege accomplishes in Part II of Grundgesetze, which contains proofs of axioms for arithmetic and several additional results concerning the finite, the infinite, and the relationship between these notions. One might think of this paper as an extremely compressed form of Part II of my book Reading Frege's Grundgesetze.

Building on findings that self-uncertainty motivates attempts to restore certainty about the self, particularly in ways that highlight one’s distinctiveness from others, we show that self-uncertainty, relative to uncertainty in general, increases creative generation among individualists. In Studies 1 to 3, high (but not low) individualists performed better on a creative generation task after being primed with self-uncertainty as opposed to general uncertainty. In Study 4, this effect emerged only among those who were told that the task measured creative as (...) opposed to analytical thinking, suggesting that the positive effects of self-uncertainty on performance are specific to tasks that bolster perceptions of uniqueness. In Study 5, self-uncertain individualists experienced a restoration of self-clarity after being induced to think about themselves as more (vs. less) creative. Implications for compensatory responses to self-uncertainty and factors that influence creativity are discussed. (shrink)

It has been known for some time that context-dependence poses a problem for disquotationalism, but the problem has largely been regarded as one of detail: one that will be solved by the right sort of cleverness. I argue here that the problem is one of principle and that extant solutions, which are based upon the notion of translation, cannot succeed.

In two recent papers, Bob Hale has attempted to free second-order logic of the 'staggering existential assumptions' with which Quine famously attempted to saddle it. I argue, first, that the ontological issue is at best secondary: the crucial issue about second-order logic, at least for a neo-logicist, is epistemological. I then argue that neither Crispin Wright's attempt to characterize a `neutralist' conception of quantification that is wholly independent of existential commitment, nor Hale's attempt to characterize the second-order domain in terms (...) of definability, can serve a neo-logicist's purposes. The problem, in both cases, is similar: neither Wright nor Hale is sufficiently sensitive to the demands that impredicativity imposes. Finally, I defend my own earlier attempt to finesse this issue, in "A Logic for Frege's Theorem", from Hale's criticisms. (shrink)

Disquotationalism is the view that the only notion of truth we really need is one that can be wholly explained in terms of such trivialities as: “Snow is white” is true iff snow is white. The 'Classical Disquotational Strategy' attempts to establish this view case by case, by showing that each extant appeal to truth, in philosophical or scientific explanations, can be unmasked as an appeal only to disquotational truth. I argue here that the Classical Strategy fails in at least (...) two cases: attributions of truth to context-dependent utterances and uses of truth psychological explanations of behavioral success or, more fundamentally, appeals to falsity in psychological explanations of behavioral failure. -/- It's my intention to turn this paper into two papers. It's become quite unwieldy as it is---not unlike "The Strength of Truth Theories". (shrink)

The current assessment of behaviors in the inventories to diagnose autism spectrum disorders (ASD) focus on observation and discrete categorizations. Behaviors require movements, yet measurements of physical movements are seldom included. Their inclusion however, could provide an objective characterization of behavior to help unveil interactions between the peripheral and the central nervous systems. Such interactions are critical for the development and maintenance of spontaneous autonomy, self-regulation and voluntary control. At present, current approaches cannot deal with the heterogeneous, dynamic and stochastic (...) nature of development. Accordingly, they leave no avenues for real-time or longitudinal assessments of change in a coping system continuously adapting and developing compensatory mechanisms. We offer a new unifying statistical framework to reveal re-afferent kinesthetic features of the individual with ASD. The new methodology is based on the non-stationary stochastic patterns of minute fluctuations (micro-movements) inherent to our natural actions. Such patterns of behavioral variability provide re-entrant sensory feedback contributing to the autonomous regulation and coordination of the motor output. From an early age, this feedback supports centrally driven volitional control and fluid, flexible transitions between intentional and spontaneous behaviors. We show that in ASD there is a disruption in the maturation of this form of proprioception. Despite this disturbance, each individual has unique adaptive compensatory capabilities that we can unveil and exploit to evoke faster and more accurate decisions. Measuring the kinesthetic re-afference in tandem with stimuli variations we can detect changes in their micro-movements indicative of a more predictive and reliable kinesthetic percept. Our methods address the heterogeneity of ASD with a personalized approach grounded in the inherent sensory-motor abilities that the individual has already developed. (shrink)

Students using Ritalin in preparation for their exams is a hotly debated issue, while meditating or drinking coffee before those same exams is deemed uncontroversial. However, taking Ritalin, meditating and drinking coffee or even education in general, can all be considered forms of cognitive enhancement. Although social acceptance might change in the future, it is interesting to examine the current reasons that are used to distinguish cases deemed problematic or unproblematic. Why are some forms of cognitive enhancement considered problematic, while (...) others are not? In this paper, we consider cognitive enhancement as the amplification or extension of core capacities of the mind, using augmentation or improvements of our information-processing systems. We will analyse cognitive enhancement in an educational setting in order to clarify the fuzzy distinction between problematic and unproblematic forms of cognitive enhancement. We will show that the apparent distinction made by many people between problematic and unproblematic enhancement is not based on any fundamental difference between these two categories. (shrink)

In both the paper "Revisability and Conceptual Change in 'Two Dogmas of Empiricism'" and in Constructing the World, David Chalmers has argued against W.V.O. Quine's claim that there are no 'analytic' sentences. I argue here that Chalmers's argument does not advance this debate.

Neo-Fregean logicists claim that Hume’s Principle (HP) may be taken as an implicit definition of cardinal number, true simply by fiat. A long-standing problem for neo-Fregean logicism is that HP is not deductively conservative over pure axiomatic second-order logic. This seems to preclude HP from being true by fiat. In this paper, we study Richard Kimberly Heck’s Two-Sorted Frege Arithmetic (2FA), a variation on HP which has been thought to be deductively conservative over second-order logic. We show that it (...) isn’t. In fact, 2FA is not conservative over n-th order logic, for all $n \geq 2$. It follows that in the usual one-sorted setting, HP is not deductively Field-conservative over second- or higher-order logic. (shrink)

​I evaluate a suggestion, floated by Kimberly Ferzan (this volume), that the twitter hashtag campaign #BelieveWomen is best accommodated by non-reductionist views of testimonial justification. I argue that the issue is ultimately one about the ethical obligation to trust women, rather than a question of what grounds testimonial justification. I also suggest that the hashtag campaign does not simply assert that ‘we should trust women’, but also militates against a pernicious striking-property generic (roughly: ‘women make false sexual assault accusations’), (...) that distorts our evaluation of women’s testimony concerning sexual assault. I conclude #BelieveWomen does not demand that we believe against the evidence, or uncritically, or be more trusting than we have evidential justification to be. Rather, it aims to bring our trust closer to what is merited by the base-rate of reliable testimony from women concerning sexual assault. (shrink)

This brief reply to Ferzan shows that her recent review of Self-Defense, Necessity, and Punishment is incoherent and completely misrepresents a central claim of mine (to the point of attributing to me the opposite claim than the one I am actually and quite clearly and explicitly making). Her other criticisms fall flat too.

In Brazil, the social demand for veterinary expertise is growing. However, there is still a shortage of professionals trained in this area to apply specific knowledge to each case. Studies and research into forensic veterinary medicine are necessary for veterinary experts to assist in investigations and legal proceedings. Veterinary medicine has subjects on its curriculum that cover the knowledge needed to apply in the fields of animal health, public health and the environment. The interaction between human and veterinary medicine, as (...) well as other areas of health, is of great importance in the prevention and control of various diseases, both in animals and humans. Some cases of infectious bovine abortion have a major impact not only on cattle farming and animal health, but also on public and environmental health. The concept of "One Health" integrates human medicine and health professionals. In this context, knowledge of infectious abortive diseases that affect animal, human and environmental health is fundamental. Cattle are affected by specific infectious abortive diseases, caused by pathogens with different forms of presentation and transmission mechanisms. These include brucellosis, leptospirosis and listeriosis, which are potentially zoonotic diseases. Controlling these diseases can contribute to effective public health actions and reduce global health risks. In order to establish the diagnosis of these diseases, it is essential to properly collect specimens from live or dead animals under biosafety and biosecurity conditions, following the chain of custody for each case. These procedures allow for greater success in diagnosing the suspected agent and facilitate the investigation of other causes. Animal health standards for the prophylaxis and control of these diseases are established by specific legislation, including those of the Ministry of Agriculture, Livestock and Supply (MALS). This literature review was based on current knowledge on the Pubmed platform, Google Scholar, articles and textbooks. The aim of this article is to identify, understand and discuss the main infectious abortive diseases of cattle in the legal and forensic context, which have an impact on cattle farming, animal health, food safety, public and environmental health. -/- Referências bibliográficas Abdullah, N.

How do we acquire the notions of cardinality and cardinal number? In the (neo-)Fregean approach, they are derived from the notion of equinumerosity. According to some alternative approaches, defended and developed by Husserl and Parsons among others, the order of explanation is reversed: equinumerosity is explained in terms of cardinality, which, in turn, is explained in terms of our ordinary practices of counting. In their paper, ‘Cardinality, Counting, and Equinumerosity’, Richard Kimberly Heck proposes that instead of equinumerosity or counting, (...) cardinality is derived from a cognitively earlier notion of _just as many_. In this paper, we assess Heck’s proposal in terms of contemporary theories of number concept acquisition. Focusing on bootstrapping theories, we argue that there is no evidence that the notion of _just as many_ is cognitively primary. Furthermore, since the acquisition of cardinality is an enculturated process, the cognitive primariness of these notions, possibly including _just as many_, depends on various external cultural factors. Therefore, being possibly a cultural construction, _just as many_ could be one among several notions used in the acquisition of cardinality and cardinal number concepts. This paper thus challenges those accounts which seek for a fundamental concept underlying all aspects of numerical cognition. (shrink)

According to the Behavioral View of consent, consent must be expressed in behavior in order to release someone from a duty. By contrast, the Mental View of consent is that normatively efficacious consent is entirely mental. In previous work, I defended a version of the Behavioral View, according to which normatively efficacious ‘consent always requires public behavior, and this behavior must take the form of communication in the case of high-stakes consent’. In this essay, I respond to two arguments by (...) proponents of the Mental View. First, Larry Alexander, Heidi Hurd and Peter Westen have argued that my view has mistaken implications concerning the culpability of different actors. I counter that my version of the view does not have these implications, as it leaves us free to draw moral and legal distinctions between different offences involving non-consensual behavior. Second, Larry Alexander and Kimberly Ferzan have argued for an analogy between consent and abandonment: on the grounds that the normative power to abandon resides in one’s will, Alexander and Ferzan concludes consent does too. I counter that abandonment requires behavior, and call into question the assumption that the ethics of property have much to teach us about the ethics of sexual consent. (shrink)

Crime and Culpability, by Larry Alexander, Kimberly Kessler Ferzan (with Stephen Morse) is a visionary work of moral and legal philosophy. Nonetheless, it is fundamentally morally misguided. In seeking to free criminal law from what the authors take to be the distorting influence of outcome luck, they arrive at a position that is overly exculpatory. It fails to hold actors liable for the harms they cause when they have taken less care they should. -/- I argue, first, that the (...) authors’ attempt to strip criminal law of outcome luck is incoherent in its own terms, and that any attempt to follow through on their program would require a much more severe loss of accountability than the authors acknowledge. I then argue that outcome luck is pervasive in our moral lives, and that, given the choice of (a) not being able to hold agents accountable for much, or (b) holding them accountable for the results of their choices, including outcomes that result in part from moral luck, the right choice is (b). I wrap up with a concluding observation about the implausible moral psychology that underlies the authors’ view of culpable action. (shrink)

Immanuel Kant és Marcel Duchamp munkássága egyaránt értelmezhető úgy, mint a művészet világát átrendező új kezdet, új távlatok forrása. Kant Az ítélőerő kritikája című munkájára úgy tekintek, mint a művészet modern paradigmájának forrására. E paradigma három alapja – a zseniális alkotó, a műalkotás és a múzeum mint a művészet temploma – levezethető a fogalom nélküli szépből. Mivel a szépnek nincs definíciója és nincsenek szabályai, az alkotó szükségszerűen eredeti kell, hogy legyen. Ezáltal a zseniális művész adja a szépművészetnek a szabályt, és (...) alkotására rávetül a zsenialitás fénye. Ezt az alkotást imádják a művészetek templomában, a múzeumban. A művészet modern paradigmáját mozgató zseniális alkotó ettől fogva a kísérletezésre van ítélve, és előbb-utóbb ennek a kísérletezésnek a tárgya maga a művészet paradigmája lesz. A huszadik századi művészek destabilizálják a művészet paradigmájának mindhárom pillérét, és ebben úttörő (kútfő) szerepet játszik Marcel Duchamp. Munkásságában megtaláljuk a műtárgy hagyományos fogalmának megszüntetésére, a művészeti világ intézményrendszerének szabotálására és a művész-szerep átértelmezésére irányuló kísérleteket. Duchamp úgy folytatja Kant művészetfelfogását, hogy a legtöbb ponton szakít vele. (shrink)

Today, there is a family of celebrated police strategies that teach the importance of cracking down on petty crime and urban nuisance as the key to effective crime control. Under the “broken windows” appellation, this strategy is linked in the public mind with New York City and the alleged successes of its police department in reducing the rate of crime over the past two decades. This paper is critical of such order maintenance approaches to policing: I argue that infringements of (...) civil liberty by such departments could be reduced if the departments looked at law more as a good to be served for its own sake and less as an instrument for the promotion of order. In other words, a shot of legalism is the correct medicine to reduce police misconduct that pierces the law’s protections of citizen freedom. -/- This Article contributes to the critical literature on broken windows policing by reassessing the work of the famous Harvard scholar (James Q. Wilson) who fathered it. The Article takes Wilson’s work and turns it on its head, drawing very different prescriptive conclusions than he did himself. (shrink)

This is a short, critical introduction to Cohen's book and argument: that socialism is justified on several grounds contrary to common opinion. I present Cohen's arguments together with some potential problems as well as responses to them.
