Classes of protection in urban forest fragments are effectiveless in structuring butterfly assemblages: landscape and forest structure are far better predictors

Urbanization is a major cause of biodiversity loss and disconnection between people and nature. For this reason, the creation and maintenance of green areas as part of the urban landscape is a common practice in cities around the world. These green areas are generally a result of particular public policies regarding how these areas can be accessed, maintained, and how they are connected to other natural fragments in the city. In an effort to investigate aspects of the ecology of such green areas of the city of Curitiba, southern Brazil, the present study measured distinct parameters of the structure of butterfly assemblages from 19 forest fragments of distinct classes of protection, testing the influence of different policies (protection category) on butterfly assemblages. Comparatively, we also tested the predictive power of landscape variables (at distinct scales) and fragment quality (e.g. diameter at breast height, density of vegetation) using Generalized Linear Models (GLMs). Overall, 14,596 individuals belonging to 412 butterfly species were recorded, but values of species diversity and composition are very heterogeneous, indicating that the protection categories do not significantly interfere with the structure of the butterfly assemblages. More important than the protection category is the forest fragment quality and landscape connectivity. Our models showed that degraded fragments tend to present a specific butterfly composition, whereas the more urbanized landscape have poor butterfly species richness. These results reinforce the importance of implementing public policies that prioritize the conservation of the quality of forest fragments in every class of protection, as well as the conservation of forest fragments throughout the urban landscape.

     

Accessibility of European museums to visitors with visual impairments

People who have visual impairments exceed 250 million persons worldwide and represent an important cohort of museum visitors. However, they experience many constraints to participation in daily life. Few studies analyse the accessibility of museums to visitors with visual impairments, and many are confined to a single museum and to a small set of strategies for improving accessibility. This article aims to identify a broad set of strategies to increase the accessibility of museums to visitors with visual impairments and analyse the accessibility of museums in four European cities. Conclusions and implications for policy-makers and museum managers, designed to promote the creation of inclusive museums, are presented.     

From an oppressed citizenship to affirmative identities: lesbian and gay political participation in Portugal

In this paper we intend to articulate a multidimensional perspective on citizenship with a psychological understanding of lesbian and gay identities' development in the context of a Southern European country: Portugal. We begin by reviewing some legal statements and institutional regulations around gay and lesbian issues and the lack of opportunities for the affirmation of a non-hegemonic (sexual) identity in Portugal. Next, we describe participation efforts developed by the Portuguese LGBT nongovernmental organizations (NGOs) and the actual results that such efforts already produced in the political and cultural attitudes toward gay men and lesbians: particularly, the legal approval of domestic same-sex partnership is emphasized as a symbolic achievement of such political struggle. Finally, we explore the implications of communitarian participation for gay and lesbian identities' development, not just in terms of collective empowerment but also in what concerns individual development and well-being.     

The Changing Informal Labour Market in Brazil: Cyclicality versus Excessive Intervention

Although following an anti-cyclical behaviour over the last decade, Brazil's informal sector seems to have grown recently as a response to excessive government intervention in the productive system. Despite high inflation and sluggish economic performance, Brazil continues to live with low unemployment and only sporadic social unrest. A substantial informal sector is thought to be acting as a cushion to help minimize labour market instability. This paper reviews the main concepts and methodologies proposed in the literature, summarizes the results obtained by different authors, and presents some additional information on the recent informalization of the Brazilian labour markets.     

Urban forest and environmental inequality in Campos dos Goytacazes,Rio de Janeiro,Brazil

Social and spatial inequality regarding environmental resources and services is one of most complex issues affecting contemporary urban life. The objective of this research is to study the spatial distribution of trees in public areas in Campos dos Goytacazes, Rio de Janeiro, Brazil. This research presents data gathered in ten neighborhoods in Campos. These neighborhoods were split into three distinct groups using wealth levels. Data obtained include the number of trees and private gardens and tree species diversity per neighborhood street. Our results demonstrate that the wealthier neighborhoods have both the highest tree biodiversity and number of trees. In contrast, the poorer neighborhoods present a low biodiversity level and fewer tree species. Our results also showed that age of the neighborhoods was not a factor in explaining the number of trees in public spaces. Socioeconomic and education levels of the population seem to play a more causal on tree quantity and species diversity. This inequality stresses a problem with environmental justice, a characteristic of Brazilian cities intrinsically connected to urban sustainability.     

Reconciliation in Remarriage to an Ex-Spouse: Individual Changes

ABSTRACT

Part of a broader investigation on remarriage to an ex-spouse, the present study aims to analyze how the main individual changes that occurred affect the reconciliation of that marriage. We conducted a qualitative study, interviewing 12 subjects, from 12 distinct heterosexual couples from Rio de Janeiro’s middle-class population, remarried to their respective ex-spouses, with children in common. To analyze the results, we employed the content analysis method, via categories, discussing the levels of change category and its two subcategories: expectations; and attitudes & behaviors. Findings indicate that greater empathy for one’s spouse and earnest willingness to take responsibility led to changes in expectations, as well as to greater respect, trust, dialogue, affection and security in the relationship, making it possible to confirm the commitment to the “new” marriage and demonstrating that reconciliation was a good choice.     

Topiramate Combined with Cognitive Restructuring for the Treatment of Gambling Disorder: A Two-Center,Randomized, Double-Blind Clinical Trial

Gambling disorder (GD) is a prevalent condition for which no pharmacological treatment has yet been approved, although there is evidence that topiramate can reduce impulsivity in GD and craving in various addictive behaviors. The goal of this study was to investigate the effectiveness of topiramate combined with cognitive restructuring for GD in a two-center, randomized, double-blind clinical trial. Participants were individuals seeking outpatient treatment for GD (n = 30), treated with either topiramate or placebo combined with a brief cognitive intervention, over a 12-week period, the dose of topiramate being tapered up during the first 8 weeks. The main outcome measures were gambling craving, behavior, and cognitive distortions; impulsivity; depression and social adjustment. Topiramate proved superior to placebo in reducing gambling craving (P = 0.017); time and money spent gambling (P = 0.007 and P = 0.047, respectively); cognitive distortions related to gambling (P = 0.003); and social adjustment (P = 0.040). We found no significant effects on impulsivity or depression. These findings are in contrast with data from a previous clinical trial with topiramate for GD. In the current study, we found that topiramate affects features specifically related to gambling addiction and had no significant effect on associated phenomena such as impulsiveness and depression. We believe that this response could be due to synergistic interaction between topiramate and the cognitive intervention.     

ICT-based solution approach for collaborative delivery of customised products

Growing interest on business collaboration motivates today’s industries, especially small and medium enterprises (SMEs) to establish and manage dynamic and non-hierarchical business networks to respond to market opportunities with added business benefits. This business environment requires concurrent work and real-time information sharing between key business partners in order to design and develop customised products. The use of traditional communication media such as e-mail, phone and fax is not satisfactory to get real-time information and is time-consuming and most often ineffective. In such environments, an Information and Communication Technology (ICT)/Web-based technology supports real-time information sharing among networked SMEs for the collaborative design and manufacturing of customised products. This study proposes an innovative ICT platform supporting SMEs collaboration, through Web and the Internet of Things technologies, which follows the Net-Challenge conceptual approach and methodological guidelines for SMEs to form and operate virtual organisations for the collaborative development and delivery of customised products. The ICT Platform was assessed in three different industry domains, namely the textile and apparel, the footwear and the machine tools, respectively. This ICT solution promotes collaboration, with substantial advantages for SMEs including the reduction of costs and delivery time and improvement of the innovation potential.     

Immigrants at new destinations: how they fare and why

We explore matched employer–employee data for a new destination of international migrants in Europe—Portugal. We conclude that the difference between the earnings of immigrants and natives with similar personal characteristics is for the most part due to the characteristics of the matches they form, immigrants being penalized on two different counts: absence of match-specific human capital and occupational downgrading. Moreover, we show that non-random sorting across workplaces has a significant detrimental effect on immigrants’ wages. This is the flip side of joining migrant-crowded workplaces.
