This study examines the influence of women in business using a sample of firms on Fortune's “100 Best Companies to Work For” list and is an extension of Bernardi et al.'s work. We use the data from Bernardi et al. to determine whether a higher representation of women on a board signals an increased commitment of a firm to a quality environment and employment characteristics necessary to establish the firm on Fortune's “100 Best Companies to Work For” list. (...) Our findings include a significant increase in the number of female directors on Fortune 500 companies between 1977 and 2001. The initial analysis of the 27 firms appearing on both Fortune's “100 Best Companies to Work For” list and the Fortune 500 in 2001 indicates a positive correlation between the number of female directors and a company's appearance on the “100 Best Companies to Work For” list.

Given two (positive) equivalence relations ∼ 1 , ∼ 2 on the set ω of natural numbers, we say that ∼ 1 is m-reducible to ∼ 2 if there exists a total recursive function h such that for every x, y ∈ ω, we have $x \sim_1 y \operatorname{iff} hx \sim_2 hy$ . We prove that the equivalence relation induced in ω by a positive precomplete numeration is complete with respect to this reducibility (and, moreover, a "uniformity property" holds). This (...) result allows us to state a classification theorem for positive equivalence relations (Theorem 2). We show that there exist nonisomorphic positive equivalence relations which are complete with respect to the above reducibility; in particular, we discuss the provable equivalence of a strong enough theory: this relation is complete with respect to reducibility but it does not correspond to a precomplete numeration. From this fact we deduce that an equivalence relation on ω can be strongly represented by a formula (see Definition 8) iff it is positive. At last, we interpret the situation from a topological point of view. Among other things, we generalize a result of Visser by showing that the topological space corresponding to a partition in e.i. sets is irreducible and we prove that the set of equivalence classes of true sentences is dense in the Lindenbaum algebra of the theory.

This paper examines the associations among social desirability response bias, cultural constructs and gender. The study includes the responses of 1537 students from 12 countries including Australia, Canada, China, Colombia, Ecuador, Hong Kong, Ireland, Japan, Nepal, South Africa, Spain, and the United States. The results of the analysis indicate that, on average, social desirability response bias decreases as a country's Individualism increases. The analysis also indicates that women scored significantly higher on Paulhus' Image Management Subscale on an overall basis and (...) for seven of the 12 country comparisons. This research serves as a caution when considering the research findings of prior international survey-based ethics research that do not include a direct measure of social desirability response bias. For example, the finding that women score higher on Paulhus' measure of social desirability response bias calls into question prior research that does not control for social desirability response bias indicating women are more ethically sensitive than men.

This research examines the association between attitudes on cheating and cognitive moral development. In this research, we use Rest's (1979a) Defining Issues Test, the Attitudes on Honesty Scale (Authors) and Academic Integrity Index (Authors); the last two are adaptations of the DIT. A total of 220 students from three universities participated in the study (66 psychology majors and 154 business majors). The data indicate that 66.4 percent of the students reported that they cheated in high school, college, or both high (...) school and college. Psychology majors scored higher than business majors on both the Defining Issues Test (Rest, 1979a) and the Attitudes on Honesty Scale (AHS, Authors). Using factor analysis, we found significant associations between students' ratings of the importance considerations present in the three cheating scenarios and their estimates of whether cheating would occur (i.e., the Academic Integrity Index). Finally, using logistic regression, we found that the scores on the Attitudes on Honesty Scale and Academic Integrity Index associate with the self-reported cheating behavior of college students.

What does it mean to be a realist about science if one takes seriously the view that scientific knowledge is always perspectival, namely historically and culturally situated? In this book, Michela Massimi articulates an original answer to this question. The book begins with an exploration of how scientific communities often resort to several models and a plurality of practices in some areas of inquiry, drawing on examples from nuclear physics, climate science, and developmental psychology. Taking this plurality in science (...) as a starting point, Massimi explains the perspectival nature of scientific representation, the role of scientific models as inferential blueprints, and the variety of scientific realism that naturally accompanies such a view. Perspectival realism is realism about phenomena (rather than about theories or unobservable entities). The book defends this novel realist view, which places epistemic communities and their situated knowledge center stage. The result is a portrait of scientific knowledge as a collaborative inquiry, where the reliability of science is made possible by a plurality of historically and culturally situated scientific perspectives. Along the way, Massimi offers insights into the nature of scientific modelling, scientific knowledge qua modal knowledge, data-to-phenomena inferences, and natural kinds as sortal concepts. Perspectival realism is ultimately realism that takes the multicultural nature of science seriously and couples it with cosmopolitan duties about how one ought to think about scientific knowledge and the distribution of the benefits resulting from scientific advancements.

It is well known that, in Peano arithmetic, there exists a formula Theor (x) which numerates the set of theorems. By Gödel's and Löb's results, we have that Theor (˹p˺) ≡ p implies p is a theorem ∼Theor (˹p˺) ≡ p implies p is provably equivalent to Theor (˹0 = 1˺). Therefore, the considered "equations" admit, up to provable equivalence, only one solution. In this paper we prove (Corollary 1) that, in general, if P (x) is an arbitrary formula built (...) from Theor (x), then the fixed-point of P (x) (which exists by the diagonalization lemma) is unique up to provable equivalence. This result is settled referring to the concept of diagonalizable algebra (see Introduction). (shrink)

This study examines the methods students use to cheat on class examinations and suggests ways of deterring using an international sample from Australia, China, Ireland, and the United States. We also examine the level of cheating and reasons for cheating that prior research has highlighted as a method of demonstrating that our sample is equivalent to those in prior studies. Our results confirm the results of prior research that primarily employs students from the United States. The data indicate that actions (...) such as having multiple versions of the examination and scrambling the questions on these versions would deter cheating. In addition, given the increased level of cheating and students' increased perception of the social acceptability of cheating in college, the data provided by our international sample also suggest that some relatively simple precautions by instructors could dramatically reduce the level of cheating on in-class examinations.

The purpose of this research is to extend prior research testing the premise that small deviations from ethical behavior lead to even larger deviations from ethical behavior. This study examines the association between a person’s willingness to bribe a police officer to avoid being issued a speeding ticket with their views on inappropriate behavior of corporate executives. Our sample of 528 participants comes from Colombia (90), Ecuador (70), South Africa (131) and the United States (237). As part of our data (...) gathering, we controlled for social desirability response bias in the responses of the students who participated in our study. Our data indicate significant differences between the views of the students from Colombia, Ecuador, and South Africa when compared to the views of the students from the United States. The analysis indicates that, for all four dilemmas, the most significant variable was the belief about how ethical it was to pay a bribe to avoid a traffic ticket. In addition, in three of our four dilemmas, Paulhus’ Impression Management Subscale, which measures social desirability response bias, was the second most significant variable. Finally, in three of the four dilemmas, the students from Colombia, Ecuador and South Africa thought the actions described in the dilemmas were less ethical than the students from the United States.

We generalize a well-knownSmullyan's result, by showing that any two sets of the kindC a = {x/ xa} andC b = {x/ xb} are effectively inseparable (if I b). Then we investigate logical and recursive consequences of this fact (see Introduction).

This research is an extension of Walker Information’s (Business Ethics: Ethical Decision Making and Cases, pp. 235–255, 1999) study on employees’ job attitudes that was conducted exclusively in the United States. Walker Information found that the reputation of the organization, fairness at work, care, and concern for employees, trust in employees, and resources available at work were important factors in an employee’s decision to remain with his or her company. Our sample includes 713 students from seven countries: Canada, Colombia, Ecuador, (...) Hong Kong, Ireland, South Africa, and the United States. When analyzing the entire sample, our data indicate that both social desirability response bias and gender were significant; however, this was not the case when the data are analyzed by country. On an individual country basis, our data suggest that the generally accepted premise that women are more ethically conscious than men was only true for the samples from the United States and Canada. The data also indicate that, while social desirability response bias was significant for the four factors suggesting ethical components for the sample from the United States, this finding was not universal.

Bernardi, Bruno | : L’analyse d’un passage peu commenté du Contrat social montre que Rousseau aborde d’une façon singulière la problématique aussi classique qu’actuelle des rapports entre liberté et sécurité. La position de sujet et celle de citoyen découlent toutes deux de la nature du corps politique. Elles sont porteuses de deux types d’exigences : la protection des personnes et des biens dans un cas, celle de la liberté civile et politique dans l’autre. Rousseau n’oppose pas ces exigences entre (...) elles mais distingue les deux ordres de priorité qu’elles rendent possibles. La politique du citoyen consiste à faire de la liberté la condition de la sécurité. (shrink)

ABSTRACTIn this paper, I discuss my personal experience of the issues that can arise when adopting critical realism in academic contexts dominated by irrealist methodological approaches. I draw inspiration for my analysis from the concept of Gramscian hegemony and the concept of ‘authenticity’. These concepts are related because hegemonic processes prevent individuals from freely expressing themselves. In my case, academic hegemony has resulted in social pressure to sacrifice my authentic critical realist self in order to achieve academic success. I also (...) discuss groupthink dynamics, suggesting that they are a mechanism by which hegemony – and denial of individual authenticity – can be achieved. This paper is meant to be a theoretical and reflexive discussion, which could be the starting point for empirical studies investigating the situation of a critical realist in a hegemonic academic context.

In this paper, we propose a framework capable of dealing with anaphora and ellipsis which is both general and algorithmic. This generality is ensured by the compination of two general ideas. First, we use a dynamic semantics which reperent effects using a monad structure. Second we treat scopes flexibly, extending them as needed. We additionally implement this framework as an algorithm which translates abstract syntax to logical formulas. We argue that this framework can provide a unified account of a large (...) number of anaphoric phenomena. Specifically, we show its effectiveness in dealing with pronominal and VP-anaphora, strict and lazy pronouns, lazy identity, bound variable anaphora, e-type pronouns, and cataphora. This means that in particular we can handle complex cases like Bach–Peters sentences, which require an account dealing simultaneously with several phenomena. We use Haskell as a meta-language to present the theory, which also consitutes an implementation of all the phenomena discussed in the paper. To demonstrate coverage, we propose a test suite that can be used to evaluate computational approaches to anaphora. (shrink)

It is well-known that, in Peano arithmetic, there exists a formula Theor (x) which numerates the set of theorems and that this formula satisfies Hilbert-Bernays derivability conditions. Recently R. Magari has suggested an algebraization of the properties of Theor, introducing the concept of diagonalizable algebra (see [7]): of course this algebraization can be applied to all these theories in which there exists a predicate with analogous properties. In this paper, by means of methods of universal algebra, we study the equational (...) class of diagonalizable algebras, proving, among other things, that the set of identities satisfied by Theor which are consequences of the known ones is decidable.

This study examined whether having attended a public, private or religious affiliated grade and/or high school influenced a college student’s ethical decision making process. We also examined whether having taken an ethics course in college influences a student’s ethical decision making process. Our sample included 508 accounting students (237 men and 271 women) from Albania, Ecuador, Ireland and the United States. Our analyses indicated no differences in ethical decision making that associated with either grade-or-high-school education. While our data showed no (...) difference in the reported attitudes between students from Ecuador and the United States after controlling for social desirability response bias, we found significant differences between the attitudes students from the United States and students from both Albania and Ireland. While gender was also significant for six of our seven scenarios, social desirability response bias was significant in all of our scenarios. (shrink)

Some years ago, Yablo gave a paradox concerning an infinite sequence of sentences: if each sentence of the sequence is 'every subsequent sentence in the sequence is false', a contradiction easily follows. In this paper we suggest a formalization of Yablo's paradox in algebraic and topological terms. Our main theorem states that, under a suitable condition, any continuous function from 2N to 2N has a fixed point. This can be translated in the original framework as follows. Consider an infinite sequence (...) of sentences, where any sentence refers to the truth values of the subsequent sentences: if the corresponding function is continuous, no paradox arises. (shrink)

This study compares the level of ethics research published in 25 business-ethics journals and the Top-40 journals for the accounting, finance, and marketing disciplines. This research documents an increasing level of ethics research in the accounting and marketing disciplines starting in 1992. While the level of finance doctorates reported by the Association to Advance Collegiate Schools of Business (AACSB) has increased at a higher rate (40.4%) than accounting (18.4%) and marketing (32.2%) since 1995, this increase has not been reflected in (...) the level of ethics scholarship in finance. The level of ethics scholarship in finance remained relatively constant between 1987 and 2005 at an average of seven coauthor-adjusted articles per year. However, both the accounting and marketing disciplines now regularly publish approximately 50 coauthor-adjusted articles each year. (shrink)

In this paper, I assess recent claims in philosophy of science about scientific perspectivism being compatible with realism. I clarify the rationale for scientific perspectivism and the problems and challenges that perspectivism faces in delivering a form of realism. In particular, I concentrate my attention on truth, and on ways in which truth can be understood in perspectival terms. I offer a cost-benefit analysis of each of them and defend a version that in my view is most promising in living (...) up to realist expectations. (shrink)

Recent investigations have revealed 1) that the isochores of the human genome group into two super‐families characterized by two different long‐range 3D structures, and 2) that these structures, essentially based on the distribution and topology of short sequences, mold primary chromatin domains (and define nucleosome binding). More specifically, GC‐poor, gene‐poor isochores are low‐heterogeneity sequences with oligo‐A spikes that mold the lamina‐associated domains (LADs), whereas GC‐rich, gene‐rich isochores are characterized by single or multiple GC peaks that mold the topologically associating domains (...) (TADs). The formation of these “primary TADs” may be followed by extrusion under the action of cohesin and CTCF. Finally, the genomic code, which is responsible for the pervasive encoding and molding of primary chromatin domains (LADs and primary TADs, namely the “gene spaces”/“spatial compartments”) resolves the longstanding problems of “non‐coding DNA,” “junk DNA,” and “selfish DNA” leading to a new vision of the genome as shaped by DNA sequences.

This paper uses a partially ordered set of syntactic categories to accommodate optionality and licensing in natural language syntax. A complex but well-studied data set pertaining to the syntax of quantifier scope and negative polarity licensing in Hungarian is used to illustrate the proposal. The presentation is geared towards both linguists and logicians. The paper highlights that the main ideas can be implemented in different grammar formalisms, and discusses in detail an implementation where the partial ordering on categories is given (...) by the derivability relation of a calculus with residuated and Galois-connected unary operators.

What is the role of attention in the dialectics of memory and communication? How far is attention functioning as a medium? Which role does attention play in the information management practices? Attention is not only fundamental to human existence but also to the process of understanding. If understanding is mediated by memory and communication then attention can be identified with the medium. So whenever you search to explain the role and mechanisms of memory in the information society, the question of (...) attention is asked immediately. Furthermore, attention can be analyzed under the following topics: as cognitive process, as subjective, intersubjective and cultural phenomenon, and as resource and medium within an 'Attention Economy'. Whereas the first aspect has to be seen in the context of empirical studies in psychology and cognitive sciences, the phenomenological, cultural, and economic aspects seem to have common points and similar implications in their theoretical approaches. In the last twenty years, the notion of attention has been the central core of several discourses in German phenomenology, economy and cultural studies. Similar to Georg Franck's theory of mental capitalism, the idea of an attention economy also was followed up in the American discourse. This article is supposed to explore the role of attention and its function as a medium within communication, cultural memory and science. (shrink)

By an unfounded chain for a function f:X→X we mean a sequence nω of elements of X s.t. fxn+1=xn for every n. Unfounded chains can be regarded as a generalization of fixed points, but on the other hand are linked with concepts concerning non-well-founded situations, as ungrounded sentences and the hypergame. In this paper, among other things, we prove a lemma in general topology, we exhibit an extensional recursive function from the set of sentences of PA into itself without an (...) unfounded chain, and we prove that every term in a Magari algebra has an unfounded chain.

The purpose of this study is to analyse the structure of written argumentative texts produced by pupils in grades 3, 5, 7 and 11 in relation to three different tasks: Group A — subjects are assigned a topic question consisting of a single statement ; Group B — subjects are given a topic question consisting of both a statement and its opposite ; Group C — subjects are given an initial and a final sentence of a text, which they have (...) to complete, and which refers to opposite opinions . Six different types of text organization were evidenced on the basis of the argumentative moves presented in the texts, the linguistic indexes used to express the relationships between the moves, the presence or absence of counter-arguments and the type of argumentation or reasoning used. The organization of the texts range from a simple affirmation of a position to a use of data or reasons to support a position, to others still in which two positions are presented in the body of a unitary structure, developed ‘in parallel’ and interconnected regularly. Our analysis found a well-defined tendency corresponding to the age levels in the types of texts produced by the subjects. The texts produced by the younger group, the pupils in elementary school, contained a fairly simple structural organization, characterized by very few argumentations or a lack of explicitness of the essential moves and a juxtaposing of arguments. The older subjects, in particular those attending secondary school, were able to produce texts which were more complex with regard to the presence and the organization of the argumentative moves, and more coherent and cohesive with respect to their articulation of opinions and use of adequate linguistic indices to analyze t topic. As regards the different types of tasks, when the subjects were presented explicitly with two opposite opinions , they developed both positions in their responses, contrary to the situation in which they produced one position when only one of two opinions was presented.

The goal of this article is to address the problem of inconsistent models and the challenge it poses for perspectivism. I analyze the argument, draw attention to some hidden premises behind it, and deflate them. Then I introduce the notion of perspectival models as a distinctive class of modeling practices whose primary function is exploratory. I illustrate perspectival modeling with two examples taken from contemporary high-energy physics at the Large Hadron Collider at the European Organization for Nuclear Research, which are (...) designed to show how a plurality of seemingly incompatible models is methodologically crucial to advance the realist quest in cutting-edge areas of scientific inquiry.

This edited collection is the first of its kind to explore the view called perspectivism in philosophy of science. The book brings together an array of essays that reflect on the methodological promises and scientific challenges of perspectivism in a variety of fields such as physics, biology, cognitive neuroscience, and cancer research, just as a few examples. What are the advantages of using a plurality of perspectives in a given scientific field and for interdisciplinary research? Can different perspectives be integrated? (...) What is the relation between perspectivism, pluralism, and pragmatism? These ten new essays by top scholars in the field offer a polyphonic journey towards understanding the view called ‘perspectivism’ and its relevance to science. (shrink)

I analyze the exploratory function of two main modeling practices: targetless fictional models and hypothetical perspectival models. In both cases, I argue, modelers invite us to imagine or conceive something about the target system, which is known to be either nonexistent or just hypothetical. I clarify the kind of imagining or conceiving involved in each modeling practice, and I show how each—in its own right—delivers important modal knowledge. I illustrate these two kinds of exploratory models with Maxwell’s ether model and (...) supersymmetric particle models at the Large Hadron Collider. (shrink)

The paper explores the adoption and operationalization of the circular economy strategy within the ambit of cooperatives, anchoring this exploration in the embeddedness theory. In more detail, our study aims to discern whether territorial and network embeddedness act as catalysts for the adoption of a circular economy strategy and subsequently influence the operationalization of circular initiatives. Given that cooperatives intrinsically emphasize community bonds and mutualistic relationships, understanding the nuances of their embeddedness can elucidate the pathways in adopting and operationalizing circular (...) economy strategies. The study draws from a survey encompassing 1116 Italian cooperatives to fathom how these organizations integrate and operationalize the circular economy in their routine operations. Data were scrutinized using a structural equation model. Outcomes reveal that both territorial and network embeddedness emerge as strong influencers of circular economy strategies, which subsequently sway the operationalization of circular initiatives. Our investigation, assessing also the mediating role of circular economy strategy adoption in relation to both territorial and network embeddedness on the assimilation of circular endeavors, offers enriched theoretical and managerial perspectives on the embeddedness theory and its practical implications.

This introduction diagnoses two tendencies among Foucaultian scholars with regard to Michel Foucault’s Discipline and Punish: While the book was initially enthusiastically embraced and its central concepts – above all “discipline” and “panopticism” – were used almost too frequently, these very concepts were often thought to be superseded by Foucault’s own development in the governmentality lectures and beyond. The articles in the special issue, however, demonstrate that Discipline and Punish, read carefully with neither uncritical enthusiasm nor progressivist dismissal, has still (...) a lot to offer for today’s critical theory and cultural analysis.

Polarity Items are linguistic expressions known for being a ‘lexically controlled’ phenomenon. In this paper we show how their behavior can be implemented in a deductive system. Further- more, we point out some possible directions to recast the deductive solution into a Tree Ad- joining Grammar system. In particular, we suggest to compare the proof system developed for Multimodal Categorial Grammar (Moot & Puite, 1999) with the Partial Proof Trees proposed in (Joshi & Kulick, 1997).
