This study investigated gender-related differences in ethical attitudes of 318 graduate and undergraduate business students. Significant differences were observed in male and female responses to questions concerning ethics in social and personal relationships. No differences were noted for survey items concerning rules-based obligations. Implications for future management are discussed.

Classical philosophy adopts the standpoint of males in the Greek polis. The consequent adumbration of the standpoint of women and noncitizen men in the oikos, the household, has implications for feminist philosophy. Two systems of action are differentiated: the domestic economy protected by the goddess Hestia, and the political economy protected by Hermes. Shifting one's standpoint to include both the oikos and the polis offers an alternative to gender as the defining issue in feminist theory.

Birth order has been examined over a wide variety of dimensions in the context of modern populations. A consistent message has been that it is better to be born first. The analysis of birth order in this paper is different in several ways from other investigations into birth order effects. First, we examine the effect of birth order in an egalitarian, small-scale, kin-based society, which has not been done before. Second, we use a different outcome measure, fertility, rather than outcome (...) measures of social, psychological, or economic success. We find, third, that being born late in an egalitarian, technologically simple society rather than being born early has a positive outcome on fertility, and fourth, that number of older siblings and sibling set size are even stronger predictors of fertility, especially for males.

One central point of contention between Hegel’s feminist critics and his defenders centers on whether he provides a model of ethical community that could effectuate harmony between the two sexes. Hegel’s account of Antigone is taken as the centerpiece of this debate because it assigns Antigone and Creon to two independent moral laws, the divine and human respectively. Many feminists argue, first, that in accepting the sexed assignment of women to the separate moral sphere of the family with its attendant (...) religious duties, Hegel subscribes to a dubious naturalistic assumption that women have a different ethical sensibility from men; and second, that this assumption leads Hegel to misconstrue women’s ethical agency. Irigaray alternatively holds that, while there is a natural difference between the sexes, Hegel’s Antigone nonetheless projects a male fantasy about woman’s ethical orientation. In contrast to both positions, Nadine Changfoot demonstrates that the logic of Hegel’s account points beyond the Greek war between the sexes to a model of ethical community that prizes divine and human law equally without necessarily perpetuating the assignment of women and men to these two, separate social spheres. The dialectic calls for, without realizing, gender equality. (shrink)

Boundary crossings in academia are rarely addressed by university policy despite the risk of problematic or unethical faculty - student interactions. This study contributes to an understanding of undergraduate college student perceptions of appropriateness of faculty - student nonsexual interactions by investigating the influence of gender and ethnicity on student judgments of the appropriateness of numerous hypothetical interactions. Overall, students deemed the majority of interactions as inappropriate. Female students judged a number of interactions as more inappropriate than did male students, (...) and with a few exceptions, Mexican American and Anglo American students were similar in their ratings of the appropriateness of faculty - student interactions. These findings suggest that universities need to be proactive in establishing guidelines concerning faculty-student boundary crossings. (shrink)

Sex determination offers an opportunity to address many classic questions of developmental biology. In addition, because sex determination evolves rapidly, it offers an opportunity to investigate the evolution of genetic hierarchies. Sex determination in Drosophila melanogaster is controlled by the master regulatory gene, Sex lethal (Sxl). DmSxl controls the alternative splicing of a downstream gene, transformer (tra), which acts with tra2 to control alternative splicing of doublesex (dsx). DmSxl also controls its own splicing, creating an autoregulatory feedback loop that ensures (...) expression of Sxl in females, but not males. A recent paper1 has shown that in the dipteran Ceratitis capitata later (downstream) steps in the regulatory hierarchy are conserved, while earlier (upstream) steps are not. Cctra is regulated by alternative splicing and apparently controls the alternative splicing of Ccdsx. However, Cctra is not regulated by CcSxl. Instead it appears to autoregulate in a manner similar to the autoregulation seen with DmSxl. BioEssays 25:1–4, 2003. © 2002 Wiley Periodicals, Inc. (shrink)

Sex determination in most organisms involves a simple binary fate choice between male or female development; the outcome of this decision has profound effects on organismal biology, biochemistry and behaviour. In the nematode C. elegans, there is also a binary choice, either male or hermaphrodite. In C. elegans, distinct genetic pathways control somatic and germline sexual cell fate. Both pathways share a common set of globally acting regulatory genes; however, germline-specific regulatory genes also participate in the decision to make male (...) or female gametes. The determination of sexual fate in the germline of the facultative hermaphrodite poses a special problem, because first sperm then oocytes are produced. It has emerged that additional layers of post-transcriptional regulation have been imposed to modulate the activities of the global sex-determining genes, tra-2 and fem-3; the balance between these activities is crucial in controlling sexual cell fate in the hermaphrodite germline.

ObjectiveIntimate partner violence has been related to emotional dependence and addictive disorders. This study aims to provide a global approach to analyse the relationship between these variables and to determine the factors underlying permanence in violent relationships.MethodsIt is a non-experimental, cross-sectional correlational design study. Participants had to have at least one dating relationship for at least 1 month to complete the questionnaire, which included the following instruments: emotional dependence scale, scale of violence in dating relationships and impulse control disorders scale.ResultsThe (...) sample consisted of 1.533 adolescents, 53.9% were male and 46.1% female, between 14 and 18 years. Emotional dependence correlated significantly with received violence. Compulsive spending is strongly associated with emotional dependence, whereas sex addiction is associated with received violence to a greater extent. Received violence mediates on emotional dependence and addictions.ConclusionIPV is a risk factor for the perpetuation of addictive behaviours. It is advisable to promote affective education for developing resilience and adequate coping. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.2 (2003) 109-118 [Access article in PDF] Editing the Rhetorical Tradition Patricia Bizzell The rhetorical tradition is always being edited. I know because I have edited it myself—that's a sort of pun, in which the words "the rhetorical tradition" refer both to a book and to the cultural phenomenon the book represents. Bruce Herzberg and I (2001) have co-edited an anthology entitled The Rhetorical Tradition: (...) Readings from Classical Times to the Present. That project also involved editing the tradition itself, because, at least since the days of Isidore of Seville, it is through inclusions and exclusions in anthologies such as ours that the rhetorical tradition is established, grows, and changes. Anthologies seem always to have played a large role in the definition of the rhetorical tradition because the accessibility of texts has so often been an issue in the study of rhetoric, whether transmission problems have been caused by the dissipation of classical learning at the end of the Roman period or are caused by the vagaries of print publication today. Then and now, the changing shape of the tradition may be discerned from the tables of contents of anthologies, a circumstance that has become especially evident to me now that we have had the opportunity to edit our volume twice. The tables of contents of the first edition, appearing in 1990, and the second, in 2001, show both some enduring similarities and some interesting differences.It is important to remember that what we inherit as the "rhetorical tradition," for blessing or curse, comprises at least three modalities: texts deemed worthy of rhetorical study, methods of analyzing those texts, and methods of teaching rhetoric according to precepts and principles derived from those texts. Such a description of our cultural legacy would seem to put texts at the center of the tradition, and indeed, anthologies focus our attention on the rhetorical tradition as a set of texts. Tables of contents organized chronologically suggest a neat progression of supposedly major works marching through the centuries, but why those particular works? In [End Page 109] the study of rhetoric as in the study of imaginative literature, scholars now realize that these supposedly inevitable textual monuments to an unbroken and progressively more sophisticated discipline are in fact quarried from among the masses of material each era produces by traditions, that is, methodological and pedagogical traditions, in how to study rhetoric. Although the tradition appears to be text-based, how we wish to analyze verbal productions and how we prefer to teach the art of producing them govern our choices of rhetorical texts to preserve, elevate, or delete. And modern histories of rhetoric have shown that the preferences governing these choices arise out of complex cultural factors relating to gender, race, social class, national identity, and more.Once upon a time, these choices were dominated by the preferences of socially privileged men who saw Western culture as the best in the world, and that culture itself as springing primarily from Greek and Roman roots. As Walter Ong (1981) has explained in Fighting for Life, these men believed that education in rhetoric must be for men only and that boys must be introduced to it via agonistic competition. From these assumptions sprang buttresses for what we might call the "traditional tradition" in the study of rhetoric, a progression of texts written by Plato, Aristotle, Cicero, Quintilian, Augustine, Erasmus, Bacon, Blair, and so on. This kind of study of rhetoric required extensive education, first, in Latin and Greek, often inculcated with the aid of corporal punishment, as Ong describes, and it persisted well into the twentieth century (though, one trusts, with much less flogging—that went out with co-education, as Ong explains). For example, until 1936, Greek was a graduation requirement at the Jesuit college where I teach, the College of the Holy Cross, and Latin was not dropped as a graduation requirement there until 1959 (the college was still all male, but the rationale for dropping the requirement appears to have centered upon the need to make room in the curriculum for pre-professional studies).

An alternative to objectifying approaches to understanding Post-traumatic Stress Disorder grounded in hermeneutic phenomenology is presented. Nurses who provided care for soldiers injured in the Iraq and Afghanistan wars, and sixty-seven wounded male servicemen in the rehabilitation phase of their recovery were interviewed. PTSD is the one major psychiatric diagnosis where social causation is established, yet PTSD is predominantly viewed in terms of the usual neuro-physiological causal models with traumatic social events viewed as pathogens with dose related effects. Biologic models (...) of causation are applied reductively to both predisposing personal vulnerabilities and strengths that prevent PTSD, such as resiliency. However, framing PTSD as an objective disease state separates it from narrative historical details of the trauma. Personal stories and cultural meanings of the traumatic events are seen as epiphenomenal, unrelated to the understanding of, and ultimately, the therapeutic treatment of PTSD. Most wounded service members described classic symptoms of PTSD: flashbacks, insomnia, anxiety etc. All experienced disturbance in their sense of time and place. Rather than see the occurrence of these symptoms as decontextualized mechanistic reverberations of war, we consider how these symptoms meaningfully reflect actual war experiences and sense of displacement experienced by service members.

Despite 20 years of official concern, women scientists in the United Kingdom are still unrepresented in the higher echelons of U.K. science, engineering, and technology and limited in their opportunities for advancement. The author attributes this to the organization and structure of scientific work, together with male “ownership” of science (even where women are a sizeable minority), rather than to the choices women make. Conflict with childbearing and child raising is significant in science more than in law and medicine because (...) external funding sources and large, rigid laboratory organizations disparage and hence disadvantage part-time scientists. Perception is another factor. Women scientists are not seen as equally committed to their work or as eager for advancement. Industrial employment, which should be freer of some of the problems in academic or research science, nevertheless shows restrictions on women’s advancement, too. (shrink)

Child sexual abuse is a global phenomenon that affects many families and appears to be increasing dramatically in South Africa. The literature on child sexual abuse focuses mainly on the victims and perpetrators while largely ignoring the experiences of non-offending mothers.

Conclusiones: La violencia infantil, continúa siendo un problema a nivel internacional. La asistencia continua a las víctimas del maltrato y a sus familias puede ayudar a reducirlo y a paliar sus consecuencias. Introduction: Child abuse is defined as mistreatment and neglect of children who are under 18. It includes physical or psychological abuse, sexual abuse, neglect, negligence and commercial exploitation or any other kind of exploitation that may cause damage to children´s health, physical development or dignity, and may endanger their survival in the context of a relationship of responsibility, trust or power. Method: A prospective, descriptive, analytical, longitudinal study was conducted using qualitative and quantitative approaches at Manuela Espejo School in Canton Ambato, Tungurahua province, Ecuador, during the period of 2013-2015 in order to determine the incidence of child abuse and provide adequate care or treatment. Results: 7.67% of children were abused; of those, males predominated at 74%. The abuse took place mainly in the family environment in the form of psychological maltreatment. Conclusions: Child abuse remains a problem internationally. Continuous assistance to victims of abuse and their families can help reduce and mitigate its consequences. (shrink)

This article draws on Foucault's concept of the exercise of power and Gramsci's concept of hegemony to examine how women used cosmetic surgery to exercise power over their bodies and lives. The analysis is rooted in two feminist perspectives on cosmetic surgery. The first argues that women who elect to have their bodies surgically altered are victims of false consciousness whose bodies are disciplined by the hegemonic male gaze. The second asserts that women who undergo elective cosmetic surgery exercise free (...) choice in controlling their bodies and lives. By examining sites wherein power is exercised by and over women, the authors argue for a synthesis of these two perspectives. They find that the women achieved greater power and control over their bodies and lives when they embodied hegemonic ideals of feminine beauty. Cosmetic surgery can be empowering for individual women while reinforcing the hegemonic ideals that oppress women as a group. (shrink)

Recent corporate governance literature on gender diversity within boards has linked the effect of an increase in gender diversity to the firm’s corporate reputation. This paper analyzes the media impact of appointing new directors of Spanish companies at a particularly significant moment, during the period from 2007 to 2010, just a year before and 3 years after the Gender Equality Act was passed. By analyzing female and male board nominations in Spanish IBEX-35 companies, the paper examines whether appointing a female (...) does have greater visibility than appointing a male, and thus a potential signaling effect for corporate stakeholders and an effect on the firm’s reputation. Results indicate that the effect on press visibility of appointing a female versus a male is negligible, although there is significant media visibility for new executive directors, in particular for the case of the only woman nominated as an executive director during the period. The paper contributes to the existing literature on gender diversity in corporate governance, specifically its effect on corporate reputation. The paper also offers information relevant to policy making and in particular to the current debate over quotas for women on boards. (shrink)

We studied the relationship between perceived social image and life satisfaction in four different cultural groups. One-hundred nine Indian (63 females, 46 males), 67 Pakistani/Bangladeshi (36 females, 31 males), 76 White British (43 females, 33 males), and 94 European Americans (43 females, 48 males) completed measures on the cultural importance of social image, positive and negative emotions, academic achievement, and perceived social image. Indian and Pakistani/Bangladeshi participants valued social image more than White British and European-American participants. (...) Consistent with this value difference, a positive perceived social image predicted life satisfaction among Indian and Pakistani/Bangladeshi participants only. For these participants, perceived social image predicted life satisfaction above and beyond the effects of emotions and academic achievement. Academic achievement only predicted life satisfaction among White British and European Americans. Emotions were significant predictors of life satisfaction for all participants. (shrink)

Mammalian sex chromosomes exhibit marked sexual dimorphism in behavior during gametogenesis. During oogenesis, the X chromosomes pair and participate in unrestricted recombination; both are transcriptionally active. However, during spermatogenesis the X and Y chromosomes experience spatial restriction of pairing and recombination, are transcriptionally inactive, and form a chromatin domain that is markedly different from that of the autosomes. Thus the male germ cell has to contend with the potential loss of X‐encoded gene products, and it appears that coping strategies have (...) evolved. Genetic control of sex‐chromosome inactivation during spermatogenesis does not involve pairing or the presence of the Y chromosome or an intact X chromosome, and may therefore be under exogenous control by the gonad. Sex‐chromosome reactivation during oogenesis and inactivation during spermatogenesis probably reflect specific meiotic events such as recombination. Understanding these phenomena may help explain other sex‐related differences in genetic recombination. (shrink)

The AAR-SBL Women’s Caucus session on ‘Beyond Down and Dirty: From Good to Great Sex’ revisited the Good Sex: Feminist Perspectives from the World’s Religions project and book with the participation of two of its co-editors, Mary E.

Scholar colleagues, Brandy Daniels, Fitri Junoes, and Alicia Besa Panganiban, presented intriguing papers on feminist religious and ethical reflections on what constitutes great sex as they examined the issues discussed by (...) feminist scholars and activist authors of Good Sex. Moreover, the session was an exhilarating dialogue of international, interreligious, and intergenerational perspectives on what women think is great sex. It was an exciting starting ground for intergenerational discussion with senior scholars, associated with the Good Sex book, providing generous, constructive, and well-considered responses to the presentations of their colleagues. The diverse international audience of masters, doctoral and senior scholars – male and female – was included in the complex, fun, and challenging discussion of sex. Amidst various issues raised, there was a consensus that discussions on great sex must address issues of safety, justice, and pleasure. Overall the session was a success as the platform for the presentations modelled a feminist method that was intentionally designed to give more time for discussion, not only among panelists but also with the audience.

Relative Energy Deficiency in Sport (RED-S) is a syndrome of impaired health and performance that occurs as a result of low energy availability (LEA). Whilst many health effects associated with RED-S have been widely studied from a physiological perspective, further research exploring the psychological antecedents and consequences of the syndrome is required. Therefore, the aim of this study was to qualitatively explore athlete experiences of RED-S. Twelve endurance athletes (female n= 10, male n= 2; M age = 28.33 years) reporting (...) past or current experiences of RED-S, associated with periods of LEA, took part in semi-structured interviews designed to explore: contexts and mechanisms underpinning the onset of RED-S; the subjective experience of RED-S; and contexts and mechanisms influencing “recovery” from RED-S. Regardless of how RED-S was initiated, all athletes experienced a multitude of physiological impairments, accompanied by significant psychological distress. This paper contributes novel understanding of the complex interplay between physiological and psychological components of RED-S from the perspective of information-rich cases. The findings suggest that system-wide educational prevention and awareness interventions are vital for athletes and support personnel, such as coaches, parents, dieticians, psychologists, and sports medicine staff.

To maximize brain plasticity after stroke, several rehabilitation strategies have been explored, including the use of intensive motor training, motor imagery, and action observation. Growing evidence of the positive impact of virtual reality (VR) techniques on recovery following stroke has been shown. However, most VR tools are designed to exploit active movement, and hence patients with low level of motor control cannot fully benefit from them. Consequently, the idea of directly training the central nervous system has been promoted by utilizing (...) motor-imagery (MI) based brain-computer interfaces (BCIs). To date, detailed information on which VR strategies lead to successful functional recovery is still largely missing, and very little is known about how to optimally integrate BCI and VR paradigms for stroke rehabilitation. The purpose of this study was to examine the efficacy of a BCI-VR system using a MI paradigm for post-stroke upper limb rehabilitation on functional assessments, and related changes in MI ability and brain imaging. To achieve this, a 60 years old male chronic stroke patient was recruited. The patient underwent a 3-week intervention in a clinical environment, resulting in 10 BCI-VR training sessions. The patient was assessed before and after intervention, as well as on a one-month follow-up, in terms of clinical scales and brain imaging using functional MRI (fMRI). Consistent with prior research, we found important improvements in upper extremity scores (Fugl-Meyer) and identified increases in brain activation measured by fMRI that suggest neuroplastic changes in brain motor networks. This study expands on the current body of evidence as more data are needed on the effect of this type of interventions not only on functional improvement but also through brain imaging to study the effect of the intervention on plasticity.

There is debate about whether the post-Fordist or high-performance work organization can overcome the disadvantages women encounter in traditional gendered organizations. Some authors argue that substituting a performance logic for control by the clock offers opportunities for combining work and family life in a more natural way. Critics respond that these organizational reforms do not address the nonresponsibility of firms for caring duties at a more fundamental level. The authors address this debate through an analysis of overtime work, using data (...) from a survey of 1,114 employees in 30 Dutch organizations. The findings reveal that post-Fordist work is associated with more overtime hours than traditional forms of work and that far from challenging gendered organization, it reproduces and exacerbates the traditional male model of work.

Introduction Future HIV vaccine efficacy trials with adolescents will need to ensure that participants comprehend study concepts in order to confer true informed assent. A Hepatitis B vaccine trial with adolescents offers valuable opportunity to test youth understanding of vaccine trial requirements in general. Methods Youth reviewed a simplified assent form with study investigators and then completed a comprehension questionnaire. Once enrolled, all youth were tested for HIV and confirmed to be HIV-negative. Results 123 youth completed the questionnaire (mean age=15 (...) years; 63% male; 70% Hispanic). Overall, only 69 (56%) youth answered all six questions correctly. Conclusions Youth enrolled in a Hepatitis B vaccine trial demonstrated variable comprehension of the study design and various methodological concepts, such as treatment group masking. (shrink)

This study examined individual, task, and environmental constraints that influence the career progression of youth Brazilian elite basketball players and the probability of reaching Novo Basquete Brasil and to determine if the association of the relative age effect is a key factor in the career progression. The sample consisted of 4,692 male players who were registered to participate in at least one U15, U17, or U22 youth Brazilian basketball championship between 2004 and 2018. Athletes who reached a high-performance level were (...) coded like NBB players. The birthdates, height, body mass, playing position, geographic region, club, competition category, and team performance were retrieved from the official data archive of the Brazilian Basketball Confederation and the National Basketball League. The maturity status was estimated using the predicted age at peak height velocity. A binary logistic regression examined the influence of each characteristic on the probability of a youth Brazilian basketball player to reach the NBB. The receiver operating characteristic curves and the associated area under the curve were used to assess the discriminant ability of the model. The taller and younger players not selected early into national teams, without specialization by playing position, who participated in U22 national championship, migrated to the southeast region, and remained in the formation process over time have a greater chance to reach the NBB. The ROC curve demonstrated an AUC of 93%. A combination of individual, task, and environmental characteristics influences the sport career of a young Brazilian basketball player in reaching the NBB. Further, early-maturing athletes have a greater chance to reach higher performances. RAE influences lower-level categories, but not a “NBB player's” career progression. The coaches, stakeholders, and practitioners should perform a holistic evaluation of sport talent in terms of a constraint-based theoretical model with the aim of avoiding bias produced by the maturational status and RAE in the youth Brazilian elite basketball.

Major neurocognitive changes occur during adolescence, making this phase as one of the most critical developmental period of life. Furthermore, this phase in life is also the time in youth substance use has its onset. Several studies demonstrated the differential associations of alcohol and cannabis use concerning the neurocognitive functioning of both males and females. Past and contemporary literature on gender-specific effects in neuroscience of addiction is predominantly based on cross-sectional datasets and data that is limited in terms of (...) measurement variability. Given the importance of gender-specific effects in addiction studies, and in order to address the two above-mentioned gaps in the literature, the present study aimed to compare neurocognitive functioning of male and female adolescents in the context of cannabis and alcohol use, while employing a longitudinal design with multiple repeated measurements. Participants were 3,826 high school students (47% female; mean age, 12.7), which were recruited from 31 high schools in the greater Montreal area. Participants were requested to complete annual surveys for five consequent years, from 7th to 11th grade, assessing their alcohol/cannabis use and neurocognitive functioning (working memory, delayed recall memory, perceptual reasoning, and inhibition control). The analytical strategy was focused on the longitudinal association between each predictor (female, male) and each of the outcomes (domains of neurocognitive functioning). Multilevel linear models assessed the association of alcohol and cannabis consumption and the four domains of neurocognitive functioning. Results revealed a gender by within-subject interaction, suggesting a weaker effect of yearly fluctuation of cannabis use on working memory among males compared to females. Our findings suggest a different pattern of neurocognitive impairment of female and male working memory after using cannabis over the course of adolescence. Early initiation of cannabis use potentially results in more spatial working memory deficits in female adolescents. This may negatively influence young females’ capacity in academic settings and lead to significant impairment in adulthood, which critically decreases the individual’s quality of life. (shrink)

Abstract:During recent years, the principle and practice of employment-at-will have been under attack. While progress has been made in eroding the practice, the principle still governs the philosophical assumptions underlying employment practices in the United States, and, indeed, EAW has been promulgated as one of the ways to address economic ills in other countries. This paper will briefly review the major critiques of EAW. Given the failure of these arguments to erode the underpinnings of EAW, we shall suggest new avenues (...) for approaching employment issues to achieve the desirable goal of employee dignity and respect.

El carácter de Alberto Blest Gana como fundador de la novela chilena mal podría ligarlo a la práctica del folletín, aunque registra numerosos títulos publicados en revistas y periódicos. Por lo demás, su filiación como aventajado discípulo de Balzac menos podría propiciar un vínculo con la literatura popular o de masas, como se desarrolló en Francia a mediados del siglo XIX. Y es que el canon literario nacional se construye a partir de una élite intelectual -ilustrada y liberal- que participa (...) de la construcción social de la Nación como la que propiciaba José Victorino Lastarria y el propio Blest Gana -en sus respectivos manifiestos literarios-, en cuya conformación la cultura popular no participa más allá de un “costumbrismo” folklórico, o como un “sabor” local, o como un “pintoresquismo” para solaz de los lectores cultos. En este artículo se indaga en los formantes folletinescos en la narrativa de Blest Gana, recurriendo a las tesis acerca de la literatura popular que han sido postuladas, entre otros, por Eco ; Martín-Barbero, Herlinghaus, Sarlo. Alberto Blest Gana, the founder of the Chilean novel, could not be linked to the practice of writing feuilleton, although a number of his works published in magazines and newspapers exist. Moreover, being an outstanding disciple of Balzac would unlikely link him to the popular or mass literature, as the one developed in France in the middle of the nineteenth century. In fact, the national literary canon is built upon an intellectual elite -enlightened and liberal- that participates in the social construction of the nation as the one fostered by José Victorino Lastarria and Blest Gana -in their respective literary manifests. In their view, the popular culture does not participate beyond a folkloric “costumbrism” or as a local “taste”, or as a “picturesque trait” for the delight of the educated readers. For this reason, this article explores the melodramatic formants in Blest Gana’s narrative, by analyzing them in light of the popular literature perspectives advocated by Eco, Martín-Barbero, Herlinghaus, and Sarlo, among others.

El siguiente trabajo se circunscribe en los dilemas que vivencia el profesional, el intelectual que se posiciona en una trinchera del conocimiento que tiene causa común con el enfrentamiento del modelo económico-social actual. Analiza la pugna que existe entre la satisfacción de necesidades de la institución donde trabaja y aquellas necesidades explicitas y latentes del grupo humano donde materializa el ejercicio disciplinario La finalidad, entonces, es sumarse al proyecto social que llama a la militancia en el campo, a la resignificación (...) del compromiso intelectual con la clase oprimida, a la lucha que deben dar en el campo los intelectuales, no solo contra el poder simbólico, sino en contra de la razón neoliberal.

Introduction: Connectedness to nature is a concept that reflects the emotional relationship between the self and the natural environment, based on the theory of biophilia, the innate predisposition to the natural environment. However, the biophobic component has largely been ignored, despite, given its adaptive functional role, being an essential part of the construct. If there is a phylogenetic component underlying nature connectedness, biophilic and/or biophobic, there should be evidence of this record from early childhood. The main aim of this study (...) is therefore to describe the emotional attributions identified in five-year-olds. Methodology: Two studies were conducted. In the first, 94 children expressed their concept of nature and made basic emotional attributions to a set of 60 images of natural and urban environments, using a software designed for the study. In the second, 39 children repeated the procedure and provided explanations for their responses. Results: The main results show that, in general, children use both positive and negative emotions, which may be related to a three-dimensional model of emotional attributions to nature. The most widely attributed emotion is happiness, for the images of both natural and built environments. However, fear is the second most common attribution. The role of happiness could be explained by a feeling of security and familiarity that the habitat of the built environment contributes to, while the importance of fear in nature could show an adaptive response of the fear of wild nature in children. This interpretation could be confirmed when analyzing specifically the emotional attributions to the natural environment, classifying the images according to biological and ecosystemic criteria. Thus, for example, more emotional attributions are explained by the "pleasantness" attributed to primary producers and landscapes (e.g. flora), versus attributions of "harm" to the images of secondary and tertiary consumers (e.g. hunters). Conclusions: These results provide evidence in favor of a didactic procedure to study emotional attributions to images of nature in preschool children. They suggest the incorporation of biophobia as an important adaptive factor in connectedness to nature and a tripartite emotional hypothesis based on the valences of the attributed emotions.

This book weaves together apparently disconnected elements of Bertrand Russell’s philosophy and social activism into a coherent narrative about the acclaimed twentieth-century intellectual’s evolving stances concerning science and technology and their role in bringing either a future Golden Age or a secular Doomsday.

AimsThis preliminary study aimed to investigate therapy-induced electrophysiological changes in persons with primary progressive aphasia. The investigated event-related potential components associated with language processing were the mismatch negativity, P300, N400, and P600.MethodsA linguistic ERP test battery and standardized language assessment were administered in four patients with PPA of which two received speech-language therapy and two did not receive therapy. The battery was administered twice with approximately 6 months in between in each patient. The results of the follow-up assessments were compared (...) to the results of the initial assessments.ResultsAlthough the results of the behavioral language assessment remained relatively stable between the initial and follow-up assessments, changes in the mean amplitudes, onset latencies, and duration of the ERP components were found in the four patients. In the two patients that did not receive SLT, an increased delay in 50% and a decreased mean amplitude in 25% of the measured ERP components were found. The electrophysiological changes found in the patients that received SLT were variable. Interestingly, the mismatch negativity and the N400 effect elicited by the categorical priming paradigm were less delayed and had an increased mean amplitude at the follow-up assessment in the patient with the non-fluent variant who received SLT. In this patient, the P600 component was absent at the initial assessment but present at the follow-up assessment.ConclusionAlthough no clear patterns in electrophysiological changes between patients who received SLT and patients who did not receive SLT were found by our preliminary study, it seems like the SLT induced improvements or compensation mechanisms in some specific language comprehension processes in the patient with the NFV. The results of this study are still preliminary because only four heterogeneous patients were included. Future studies should include larger patient groups of the three clinical variants because the therapy-induced electrophysiological changes might differ depending on the clinical variant and the underlying pathology.

When solving problems, like making predictions or choices, people often “sample” possibilities into mind. Here, we consider whether there is structure to the kinds of thoughts people sample by default—that is, without an explicit goal. Across three experiments we found that what comes to mind by default are samples from a probability distribution that combines what people think is likely and what they think is good. Experiment 1 found that the first quantities that come to mind for everyday behaviors and (...) events are quantities that combine what is average and ideal. Experiment 2 found, in a manipulated context, that the distribution of numbers that come to mind resemble the mathematical product of the presented statistical distribution and a (softmax-transformed) prescriptive distribution. Experiment 3 replicated these findings in a visual domain. These results provide insight into the process generating people’s conscious thoughts and invite new questions about the value of thinking about things that are both likely and good. (shrink)

This book provides an up-to-date revision of materialism’s central tenets, its main varieties, and the place of materialistic philosophy vis a vis scientific knowledge. Materialism has been the subject of extensive and rich controversies since Robert Boyle introduced the term for the first time in the 17th century. But what is materialism and what can it offer today? The term is usually defined as the worldview according to which everything real is material. Nevertheless, there is no philosophical consensus about whether (...) the meaning of matter can be enlarged beyond the physical. As a consequence, materialism is often defined in stark exclusive and reductionist terms: whatever exists is either physical or ontologically reducible to it. This conception, if consistent, mutilates reality, excluding the ontological significance of political, economic, sociocultural, anthropological and psychological realities. Starting from a new history of materialism, the present book focuses on the central ontological and epistemological debates aroused by today’s leading materialist approaches, including some little known to an anglophone readership. The key concepts of matter, system, emergence, space and time, life, mind, and software are checked over and updated. Controversial issues such as the nature of mathematics and the place of reductionism are also discussed from different materialist approaches. As a result, materialism emerges as a powerful, indispensable scientifically-supported worldview with a surprising wealth of nuances and possibilities. (shrink)
