Landscape urbanization threatens plant phylogenetic diversity in the Brazilian Atlantic Forest

Urbanization causes species loss around the world, but its effects on phylogenetic diversity are poorly known in tropical forests. Using a patch-landscape approach in an urbanizing region of the Brazilian Atlantic Forest, we tested whether the increase in landscape urbanization reduces plant species density, phylogenetic richness and divergence, and increases the relatedness among co-occurring individuals and species. We assessed plant responses to urbanization in adult (diameter at breast height?>?10 cm) and sapling communities (2.5–10 cm diameter) separately, as saplings are proxies of the future flora. We sampled 2860 woody plants belonging to 155 species in nine circular landscapes with urbanization level varying from 0% to 45%, and estimated the relatedness among the species that have increased and decreased in relative abundance in more urbanized landscapes (winner and losers, respectively). As expected, species density and phylogenetic richness decreased with the increase in urbanization. These responses were consistent for adult and sapling communities, suggesting a persistent loss of species and lineages in more urbanized landscapes. Contrary to our expectations, phylogenetic divergence and structure did not respond to urbanization, indicating that the more urbanized landscapes still retain much evolutionary history. However, because the relatedness among winners was greater than among losers, it is likely that the phylogenetic divergence gradually reduces and the relatedness increases, resulting in impoverished forests with uncertain ability to provide ecosystem services such as carbon storage and pest control. This environmental cost should be taken into account to align urban sprawl with biodiversity conservation.     

The event of death: Reflections on the dynamics of emotions and embodied resistance in the Moroccan Contexts of hirak (movement) and la hirak ((non)movement)

This paper studies the role of emotions in creating spectacular revolt situations. We underline the travelling competence of sentiments and their power in crafting trans-local moments of embodied resistance. In contemporary Moroccan society, the adaptation of the Bouazizian style of protest has been a reaction to the prevailing feelings of worthlessness gripping the common citizen. The images of wasted beings in the post-2011 atmosphere have been associated with instances of social insurgence, by individuals who attempt self-immolation, or citizens treated by figures from the centre (e.g. police, public figures) in a way that inculcate in them powerful feelings of abjection, after which they feel irreparably delinked from their sense of humanity. This paper seeks to demonstrate how practices of al-hogra (humiliation) have produced cultural forms of abjection that could also be traced in the way common people inferiorize one another in everyday life through the use of a terminology of trash. By disclosing people’s non-subtle armaments of protest (i.e. self-immolation), we contend that resistance and its various trances, as well as the emotions that prompt them, have their origin in the reality of the body, realistic visions of the body owner and his/her awareness of the potential for realization (through it). Hence we will examine how vulnerable people manipulate the three conditions of corporeality, corporealism and corporealization, to subvert the humiliation and symptoms of social death imposed on them by the regime.     

Toward total student health: A qualitative pilot study

Objective: Colleges should aim to cultivate healthy behaviors among students by addressing alterations in wellness students view as important. The purpose of this study was to determine the self-perceived wellness-related concerns and behaviors of college students. Participants: Thirty-seven undergraduate students participated in this study between January and March 2017. Methods: Focus groups served as a data collection method. Groups were recorded and transcribed verbatim. Directed and conventional approaches to data analyses were employed. Results: Participants expressed concern regarding four campus wellness topics: nutrition, economics, mental health, and campus safety. Participants offered solutions for improving campus wellness, representing a fifth theme. Conclusions: Health concerns for college students and realistic solutions to address concerns were identified across focus groups. Overall, students cared about their own health, as well as the well-being of other students. Future directions include conducting a Web-based survey among students to assess prevalence and impact of select health and wellness topics.     

A new financial stress index model based on support vector regression and control chart

Financial stress index (FSI) is considered to be an important risk management tool to quantify financial vulnerabilities. This paper proposes a new framework based on a hybrid classifier model that integrates rough set theory (RST), FSI, support vector regression (SVR) and a control chart to identify stressed periods. First, the RST method is applied to select variables. The outputs are used as input data for FSI–SVR computation. Empirical analysis is conducted based on monthly FSI of the Federal Reserve Bank of Saint Louis from January 1992 to June 2011. A comparison study is performed between FSI based on the principal component analysis and FSI–SVR. A control chart based on FSI–SVR and extreme value theory is proposed to identify the extremely stressed periods. Our approach identified different stressed periods including internet bubble, subprime crisis and actual financial stress episodes, along with the calmest periods, agreeing with those given by Federal Reserve System reports.     

Conceptualization and Measurement of Adolescent Prosocial Behavior: Looking Back and Moving Forward

The struggle to cast a net around the numerous ways prosocial behavior is expressed lends itself to the absence of widely accepted methods of measurement. Additionally, research intent on evaluating the psychometric properties of current approaches has been somewhat limited. Weaving together seminal as well as contemporary research, the current review focuses on how these conceptual and measurement issues pertain to adolescent studies (in an intentional effort to offset the somewhat disproportionate focus directed toward prosocial development in infants, children, and adults). Recommendations to address current limitations and attain a more nuanced understanding of the construct are presented and discussed.

A Scoping Review of Challenges in Adult Intimate Relationships After Childhood Sexual Abuse

Childhood sexual abuse is a severe problem worldwide. Childhood sexual abuse can be detrimental to children and their abilities to cope with and communicate in their subsequent adult intimate relationships. The aim of this review was to generate and summarize knowledge about how childhood sexual abuse manifests in adult intimate relationships so healthcare professionals can incorporate this knowledge into treatment and care. A scoping review methodology was selected because it supports examination of the extent, range, and nature of research activity. A content analysis of the studies included in this review led to three thematic categories of challenges in adult intimate relationships after childhood sexual abuse: (a) relationship satisfaction, (b) sexual satisfaction, and (c) communication and trust.     

Waste’s dominion: the gymnastics of value in informal markets*

Abstract

This paper examines sites of informal trade in Morocco, what the locals call joutiat (sing. joutia). It departs from the semantic and real-world politics of disposability (of objects and people), to unravel the underlying meanings of the joutia as a contested space. The joutia is a place where not only objects of value wait to be rediscovered, but also where invisible and socially underprivileged beings perpetually ransack heaps of trade articles to unmask a hidden gem. I provide an account of the social dynamics of abjection inside/outside the joutia, arresting the ambivalence of objects, which – as they keep vacillating between value and lack of it – turn into “treashure”. I use this neologism, which combines two antithetical terms (trash and treasure), to (a) put into question issues of visibility and invisibility in informal Moroccan enterprises, (b) crystallise the paradoxes of being and becoming inside and outside the market arena, (c) offer a profound reflection on the absurd nature of value in the informal landscapes of (non)random economy and (d) demonstrate that the forms of abjection inside the market have their origin elsewhere.     

Reading Ibn Khaldun in the Formative Period of Sociology

‘Abd al-Rahman Ibn Khaldun (1332-1406), the founder of the science of society, became known to modern sociologists during the formative period of sociology, that is, the late nineteenth and early twentieth century. There was something of a reception of Ibn Khaldun in Europe at that time by sociologists and other scholars who were not necessarily involved with Islamic or West Asian studies. In fact, the reception of Ibn Khaldun by modern scholars in the West can be differentiated into Eurocentric or Orientalist as opposed to more disciplinary attitudes. While much has been said about the Eurocentric reception of Ibn Khaldun, less is discussed about the disciplinary approach to Ibn Khaldun among thinkers who wrote when the modern science of sociology was emerging in Europe. This special issue on Ibn Khaldun in the Formative Period of Sociology provides English translations of six articles originally written in Italian, French, German, Polish, Spanish and Turkish between 1896 and 1934. Not all of these articles were written by sociologists. Together, they provide some background as to how Ibn Khaldun was conceived of in non-area studies circles, in the social sciences and humanities.     

Violence and political culture in Mozambique

This article is an attempt at developing a lens through which political culture in Mozambique can be analysed, described and interpreted. It is based on the notion of a political teleology that emerged out of the conditions within which the country fought for its independence. The paper argues that violence in a symbolic and physical form played a central role in the constitution of this political teleology by, on the one hand, allowing the liberation movement to produce an account of Mozambican history which both gave legitimacy to its own struggle while at the same time undermining alternative accounts and, on the other, set the scene for the implementation of a national project that came to be primarily concerned with the reproduction of the claim to power of the liberation movement. Forty years of independence in Mozambique offer an ideal time frame to attempt the construction of such a lens.
