Alternatives to convenience sampling (CS) are needed for HIV/STI surveillance of most-at-risk populations in Latin America. We compared CS, time space sampling (TSS), and respondent driven sampling (RDS) for recruitment of men who have sex with men (MSM) and transgender women (TW) in Lima, Peru. During concurrent 60-day periods from June-August, 2011, we recruited MSM/TW for epidemiologic surveillance using CS, TSS, and RDS. A total of 748 participants were recruited through CS, 233 through TSS, and 127 through RDS. The TSS (...) sample included the largest proportion of TW (30.7 %) and the lowest percentage of subjects who had previously participated in HIV/STI research (14.9 %). The prevalence of newly diagnosed HIV infection, according to participants' self-reported previous HIV diagnosis, was highest among TSS recruits (17.9 %) compared with RDS (12.6 %) and CS (10.2 %). TSS identified diverse populations of MSM/TW with higher prevalences of HIV/STIs not accessed by other methods. (shrink)

Using data collected at two phases, this study examines why and how ethical leadership behavior influences employees’ evaluations of organization-focused justice, i.e., procedural justice and distributive justice. By proposing ethical leaders as moral agents of the organization, we build up the linkage between ethical leadership behavior and the above two types of organization-focused justice. We further suggest trust in organization as a key mediating mechanism in the linkage. Our findings indicate that ethical leadership behavior engenders employees’ trust in their employing (...) organization, which in turn promotes their justice perceptions toward the organization. The theoretical and practical implications of these findings are discussed, and some directions for future research are suggested. (shrink)

International research, sponsored by for-profit companies, is regularly criticised as unethical on the grounds that it exploits research subjects in developing countries. Many commentators agree that exploitation occurs when the benefits of cooperative activity are unfairly distributed between the parties. To determine whether international research is exploitative we therefore need an account of fair distribution. Procedural accounts of fair bargaining have been popular solutions to this problem, but I argue that they are insufficient to protect against exploitation. I argue instead (...) that a maximin principle of fair distribution provides a more compelling normative account of fairness in relationships characterised by extreme vulnerability and inequality of bargaining potential between the parties. A global tax on international research would provide a mechanism for implementing the maximin account of fair benefits. This model has the capacity to ensure fair benefits and thereby prevent exploitation in international research. (shrink)

In this article, I develop a framework for re-imagining gender-based violence not as an outgrowth of patriarchy but as a response to the threat of gender integration and the inversion of the gendered hierarchy. I argue that this reconceptualization is critical to re-envisioning not just research but also prevention and intervention strategies. I begin by identifying two reasons for the stalled revolution in reducing rates of gender-based violence: the focus on intimate partner violence and sexual violence as distinct rather than (...) as similar tools that are simply deployed in different spaces, and the de-centering of Black feminist voices and the obscuring of the similarities between gender-based violence and racialized violence. Finally, I conclude with recommendations to transform policies and hegemonic ideologies that limit the impact of gender-based violence—including by holding perpetrators accountable—and render it socially unacceptable, thus creating the foundation for building social institutions that are diverse, inclusive, and equitable.

This paper introduces the reconstitutor as a comprehensive unit of heredity within the context of evolutionary research. A reconstitutor is the structure resulting from a set of relationships between different elements or processes that are actively involved in the recreation of a specific phenotypic variant in each generation regardless of the biomolecular basis of the elements or whether they stand in a continuous line of ancestry. Firstly, we justify the necessity of introducing the reconstitutor by showing the limitations of other (...) evolutionary conceptions of the unit of heredity, such as the replicator, the reproducer, and the Darwinian individual. We argue that these conceptions are based on the requirement of lineage formation, which we argue to be unnecessary for the existence of evolutionary heredity. In the second part, we introduce the reconstitutor, which we base on the concept of Stability of Traits, and illustrate how it covers cases of hereditary phenomena not covered by the previous accounts. Secondly, we illustrate how the reconstitutor could serve as a platform to rethink ecological inheritance and other forms of inheritance that have been recently introduced under the song/singer model of evolution.

The assumption that commonsense psychological explanations of behavior are causal underlies current debate between simulation theory and theory theory regarding the nature of cognitive mechanism responsible for our folk psychological practices. Theory theorists claim that these explanations are subsumed by the covering law model of causal explanation. Simulationists are not explicit about the nature of the explanations produced by simulation. In what follows, I propose a set of plausible conditions that a correct causal simulation-produced folk psychological explanation will satisfy and (...) point out two prima facie problems. In discussing a possible solution, I discover that the latter incurs the need for some sort of causal law. An examination of two likely candidates for these laws reveals that neither is capable of playing the role required. I then suggest alternative routes that simulationists might explore in order to provide simulation theory with a sorely-needed account of the nature of the explanations produced by simulation.

Underlying the current debate between simulation theory and theory theory is the assumption that folk psychological explanations of behavior are causal. Simulationists Martin Davies, Tony Stone, and Jane Heal claim that folk psychological explanations are explanations that make sense of another person by citing the thoughts important to the determination of his behavior on a given occasion. I argue that it is unlikely these explanations will be causal. Davis et al. base their claim on the assumption that a certain isomorphism (...) obtains between the cognitive mechanisms of human beings. Investigation into the nature of the isomorphism required reveals that it is of a sort that is unlikely to obtain. I suggest that in order to maintain their challenge to theory theory, simulationists must either motivate and describe a non-causal simulation-based account of folk psychological explanation or else delineate a causal account that attributes a nonessential, heuristic role to simulation.

Grounded in Bandura’s social cognitive theory of moral thought and action, we develop a conceptual model linking supervisors’ perceptions of organizational injustice and abusive supervision with moral disengagement mechanisms acting as the underlying process. Specifically, we elaborate why and how supervisors’ experiences of each type of injustice would trigger their adoption of distinctive moral disengagement mechanisms, which in turn lead to their abusive supervisory conduct. The present conceptual model sheds new light on linking organizational injustice to abusive supervision from a (...) moral perspective. In addition, it also provides important theoretical and managerial implications to our current understanding of why and how abusive supervision happens. (shrink)

The evolutionary implications of environmental change due to organismic action remain a controversial issue, after a decades—long debate on the subject. Much of this debate has been conducted in qualitative fashion, despite the availability of mathematical models for organism–environment interactions, and for gene frequencies when allele fitness can be related to exploitation of a particular environmental resource. In this article we focus on representative models dealing with niche construction, ecosystem engineering, the Gaia Hypothesis and community interactions of Lotka–Volterra type, and (...) show that their quantitative character helps bring into sharper focus the similarities and differences among their respective theoretical contexts.

Wakandan women can play stereotypically male roles because of the political construction of Wakandan identity. Wakandan women emerge, for starters, in a radically different cultural context than women of color in other countries and cultures. Despite their tacit representation of feminist ideals, Wakandan women resist the full‐throated feminism we associate with the modern era: the no‐husband, no‐children feminism championed by the French philosopher Simone de Beauvoir. In 1966 Black Panther, the Marvel comic superhero, made his debut during the height of (...) second‐wave feminism. Back in Wakanda, M'Baku's renouncement of Shuri's non‐domestic activities makes an implicit appeal to the feminine mystique. Recognizing feminist and womanist elements within Wakanda helps explain the masculine and feminine performances of Wakandan women. Demystifying Wakanda requires us to recognize and reckon with The Panther Mystique : uncoerced appropriations of masculine and feminine norms for the sake of collective, communal freedom. (shrink)

Research on mental health of non-professional caregivers has focused on caregivers of people with specific diseases, especially dementia. Less is known about caregivers of people with other diseases. The aims of this study were (a) to determine the caregivers’ emotional state in a random sample of caregivers of people in situations of dependency, (b) to analyze the association between each disease of the care-recipient (a variety of 23 diseases included in the International Classification of Diseases) and the emotional state of (...) the caregiver, and (c) based on the theoretical model, to analyze the relationship of the different study variables in the appearance of the emotional distress of the caregiver. A sample of 491 non-professional caregivers was selected randomly (89.0% women, average age 55.3 years). Trained psychologists collected sociodemographic and care-related characteristics and evaluated the global emotional distress, somatic symptoms, anxiety-insomnia, social dysfunction, depression, probable mental disorder case, self-esteem and social support. It was found that (a) the caregivers showed moderate emotional distress, and 33.8% presented a probable mental disorder. (b) Caring for a care-recipient with cat's cry syndrome or epilepsy was related to suffering from social dysfunction, and caring for a care-recipient with autism was related to having a probable mental health case. (c) Social support mediated the relationship between social class, daily hours of care, monthly family income, self-esteem and global emotional distress. There is an important impact on the emotional state of the caregivers. This impact was similar in caregivers of care-recipients with different diseases, except in caregivers caring for a care-recipient with cat's cry syndrome or epilepsy (related to social dysfunction), and in caregivers caring for a care-recipient with autism (related to having a probable mental health case).

It is increasingly argued that polymathy—vocational and avocational pursuits in multiple domains—is deeply associated with creativity and innovation, and that its development enables the creation of important bridges between otherwise fragmented, dispersed sets of knowledge. Nevertheless, the dominant culture in both industry and academia is still that of narrow specialization. In this paper, we argue that in the context of COVID-19 crisis, with its wicked and transdisciplinary nature, the disciplinary approach of specialization is ill-suited to solve our increasingly complex problems, (...) and that polymathic thinking can be a crucial asset in this regard. Drawing on different literature strands, we first examine the interplay between polymathy and other well-developed constructs in personality and temperament research. We then advance theoretical predictions regarding the relationship between trait polymathy and resilience in the COVID-19 crisis. After that, we discuss learnable strategies that can be used in complex, uncertain and adverse situations, which are associated with development of a more polymathic set of knowledge. Later, we discuss how it may be possible to better capitalize on the key features of polymathic thinking at the societal level. Finally, we conclude with a reflection on the adequacy of our current institutions for dealing with complex problems, and we underscore the crucial role of polymathic thinking in an increasingly complex and interrelated world.

Psychotherapy clients read two consumer-oriented brochures: a general brochure on psychology and a brochure on the topic of client-therapist intimacy. Half of the participants read the general brochure first and the brochure on client-therapist intimacy second, and half the participants did the reverse. Participants reported favorable reactions to the brochures, indicating they thought both should be made available to psychotherapy clients; that neither were too long, too sensitive, or too difficult to read; and that the brochures should be made available (...) early during the therapeutic process. After reading the client-therapist intimacy brochure, participants also showed some changes in Likert-type scores measuring attitudes regarding intimate contact between clients and therapists. Although participants were more negative about issues of sexual misconduct after reading the client-therapist intimacy brochure, they did not indicate a decrease in trust of therapists, nor did they indicate a greater likelihood of filing a false complaint. We concluded that therapists' reservations about presenting clients with factual information regarding therapist sexual exploitation of clients are not empirically founded. (shrink)

Variations in levels of apolipoprotein E have been tied to the risk and progression of Alzheimer's disease . Our group has previously compared and contrasted the promoters of the mouse and human ApoE gene promoter sequences and found notable similarities and significant differences that suggest the importance of the APOE promoter's role in the human disease. We examine here three specific single-nucleotide polymorphisms within the human APOE promoter region, specifically at -491 , -427 , and at -219 upstream from the (...) +1 transcription start site. The -219 and -491 polymorphic variations have significant association with instance of AD, and -491AA has significant risk even when stratified for the APOEepsilon4 allele. We also show significant effects on reporter gene expression in neuronal cell cultures, and, notably, these effects are modified by species origin of the cells. The -491 and -219 polymorphisms may have an interactive effect in addition to any independent activity. DNA-protein interactions differ between each polymorphic state. We propose SP1 and GATA as candidates for regulatory control of the -491 and -219 polymorphic sites. This work's significance lies in drawing connection among APOE promoter polymorphisms' associations with AD to functional promoter activity differences and specific changes in DNA-protein interactions in cell culture-based assays. Taken together, these results suggest that APOE expression levels are a risk factor for AD irrespective of APOEepsilon4 allele status. (shrink)

We give anecdotal accounts from our own experience of scientific theories which have been generally accepted as the ruling opinion long after sufficient evidence has been collected for their disproof. This has led us to the opinion that the normal scientific process, of working hypothesis followed by experimental test aimed at disproof, is being replaced by the ruling opinion followed by experiment aimed at confirmation. The apparently widespread adoption of this procedure may be postulated to arise in part from the (...) need for workers entering a new field of study to obtain grants and to get their results published.

The progress of Mathematics during the nineteenth century was characterised both by an enormous acquisition of new knowledge and by the attempts to introduce rigour in reasoning patterns and mathematical writing. Cauchy’s presentation of Mathematical Analysis was not immediately accepted, and many writers, though aware of that new style, did not use it in their own mathematical production. This paper is devoted to an episode of this sort that took place in Spain during the first half of the century: It (...) deals with the presentation of a method for numerically solving algebraic equations by José Mariano Vallejo, a late Spanish follower of the Enlightenment ideas, politician, writer, and mathematician who published it in the fourth (1840) edition of his book Compendio de Matemáticas Puras y Mistas, claiming to have discovered it on his own. Vallejo’s main achievement was to write down the whole procedure in a very careful way taking into account the different types of roots, although he paid little attention to questions such as convergence checks and the fulfilment of the hypotheses of Rolle’s Theorem. For sure this lack of mathematical care prevented Vallejo to occupy a place among the forerunners of Computational Algebra. (shrink)

Explaining the behaviour of ecosystems is one of the key challenges for the biological sciences. Since 2000, new-mechanicism has been the main model to account for the nature of scientific explanation in biology. The universality of the new-mechanist view in biology has been however put into question due to the existence of explanations that account for some biological phenomena in terms of their mathematical properties (mathematical explanations). Supporters of mathematical explanation have argued that the explanation of the behaviour of ecosystems (...) is usually provided in terms of their mathematical properties, and not in mechanistic terms. They have intensively studied the explanation of the properties of ecosystems that behave following the rules of a non-random network. However, no attention has been devoted to the study of the nature of the explanation in those that form a random network. In this paper, we cover that gap by analysing the explanation of the stability behaviour of the microbiome recently elaborated by Coyte and colleagues, to determine whether it fits with the model of explanation suggested by the new-mechanist or by the defenders of mathematical explanation. Our analysis of this case study supports three theses: (1) that the explanation is not given solely in terms of mechanisms, as the new-mechanists understand the concept; (2) that the mathematical properties that describe the system play an essential explanatory role, but they do not exhaust the explanation; (3) that a non-previously identified appeal to the type of interactions that the entities in the network can exhibit, as well as their abundance, is also necessary for Coyte and colleagues’ account to be fully explanatory. From the combination of these three theses we argue for the necessity of an integrative pluralist view of the nature of behaviour explanation when this is given by appealing to the existence of a random network.
