Effects of long-term landscape dynamics and city growth on biodiversity in the Mediterranean: the case study of Montpellier,France

In the Mediterranean, long-term land-use changes have resulted into landscape mosaics composed of very few ancient woodland remnants scattered across extended post-agricultural woodlands. Patches of ancient woodlands are now suffering rapid urban growth that reduces their area and impact their associated biodiversity. Here we use the case study of Montpellier, one of the most dynamic cities in France, to 1) characterize temporal changes in land covers (between 1860 and 2006) in its area, and 2) using two guilds of fungal bioindicators (i.e., polypores and lichens), to compare biodiversity stakes between ancient and secondary Mediterranean woodlands. We used a combination of historical maps, archives, fungal collections and field survey in eight Quercus ilex patches (4 ancient versus 4 recent replicates) to reconstruct landscapes dynamics and assess biodiversity changes. From the 19th to the 21st century, over half (52.4%) of the ancient woodlands within Montpellier were replaced by other land covers, mainly by urban equipment, while secondary patches (16.8% of the total area) were naturally established. Remaining ancient woodlands show multi-layered vegetation made of multi-secular Pinus halepensis dominating a dynamic understorey made of Quercus ilex and various Mediterranean shrubs. Polypores, but not macrolichens, tended to differ in community composition between ancient and recent woodland patches, with the highest diversity found in ancient woodlands. This study highlights that urban woodland patches of contrasted histories harbour distinct biodiversity stakes to be included in urban planning and provide valuable areas to evaluate biodiversity patterns and dynamics.     

Women on strike: mobilizing against reproductive injustice in Poland

The paper employs a lens of reproductive justice (RJ) to discuss the events of the 2016 mobilization against a total abortion ban proposal in Poland. By presenting the context of women’s rights in Poland, especially the abortion debates, we argue that the 2016 Women’s Strike showed that taking a stand for reproductive justice was countered by governmental actions. By using a case study approach, the paper analyzes the Strike as a tumultuous act of women’s solidarity while simultaneously assessing its implications for RJ issues. We discuss the aftermath and the socio-political reticence to acknowledge the complexities of women’s lives and reproductive choices. Further, we provide arguments for applying the RJ framework into discerning the notion of ideal citizens and gendered social control in Poland. This localized analysis has a global relevance by reflecting the impact of worldwide trends in women’s rights activism and RJ in the context of resurfacing nationalisms and populism.     

Gender differences in gambling preferences and problem gambling: a network-level analysis

Most gambling studies have a gender-blind research approach, although a large body of scientific evidence suggests that gambling in females is on the rise and that males and females have different gambling behaviours and experience specific gambling-related harm. This study addressed these gender differences using a network analysis, an innovative approach considering disorders/concepts as dynamic systems of interacting symptoms/items. Data on gambling activities, problem gambling, substance use and mental health were collected in a representative sample of French adult gamblers (n = 8805). The study capitalized on the network analysis directly to compare associations of specific gambling activities with gambling disorder symptoms separately for both genders. The network analysis revealed that problem gambling was strongly associated with gambling machines among females, whereas it was related to sports betting, poker and casino games among males. The networks that included substance use and mental health showed that substance use was related to specific gambling activities. These findings confirm the links between various gender-specific gambling patterns and problem gambling and suggest a need to consider these gender differences to improve prevention efforts. More broadly, the present study further supports the importance of gender differences for gambling research and policy.     

Unmasking the crowd: participants’ motivation factors,expectations, and profile in a crowdsourced law reform

This article examines the demographic characteristics, motivations, and expectations of participants in a crowdsourced off-road traffic law reform in Finland. We found that the participants were mainly educated, full-time working professional males with a strong interest in off-road traffic. Though a minority, the women participating in the process produced more ideas than the men. The crowd was motivated by a mix of intrinsic and extrinsic factors. Intrinsic motivations included fulfilling civic duty, affecting the law for sociotropic reasons, to deliberate with and learn from peers. Extrinsic motivations included changing the law for financial gain or other benefits. Participation in crowdsourced policy-making was an act of grassroots advocacy, whether to pursue one’s own interest or more altruistic goals, such as protecting nature. The motivations driving the participation were in part similar to those observed in traditional democratic processes, such as elections as well as other online collaborations such as crowdsourced journalism and citizen science. The crowds’ behavior was, however, paradoxical. They participated despite the fact that they did not expect that their contributions would affect the law.     

From the hidden welfare state to the hidden part of welfare state reform: Analyzing the uses and effects of fiscal welfare in France

This article argues that fiscal welfare in Europe not only forms part of the “hidden welfare state” (Howard, 1997 ), but also constitutes an important yet understudied—and therefore hidden—element of welfare state reform. Using the example of France, and relying both on available data and on an exhaustive database of social tax expenditures (STEs) compiled for 2014, the article begins by providing an overview of the structure of STEs in France (section 2 ). It then analyzes the specific uses and effects of STEs in the fields of employment, health care, and pensions. In particular, it shows, first of all, how STEs have constituted a privileged instrument for circumventing certain institutional features such as high levels of minimum wage and of social security contributions in the field of employment (section 3 ). Second, it also shows that STEs have been used to quietly divert resources away from the earmarked social security funds and into collective private insurance funds, thus fueling their development, in the case of health care and pensions (section 4 ). Lastly, the article engages with the notion of the “social division of welfare” (Titmuss, 1958 ) by considering some of the distributional effects of fiscal welfare in France (section 5 ), before concluding (section 6 ).     

On the use of extreme value tail modeling for generalized pairwise comparisons with censored outcomes

In randomized clinical trials, methods of pairwise comparisons such as the ‘Net Benefit’ or the ‘win ratio’ have recently gained much attention when interests lies in assessing the effect of a treatment as compared to a standard of care. Among other advantages, these methods are usually praised for delivering a treatment measure that can easily handle multiple outcomes of different nature, while keeping a meaningful interpretation for patients and clinicians. For time-to-event outcomes, a recent suggestion emerged in the literature for estimating these treatment measures by providing a natural handling of censored outcomes. However, this estimation procedure may lead to biased estimates when tails of survival functions cannot be reliably estimated using Kaplan–Meier estimators. The problem then extrapolates to the other outcomes incorporated in the pairwise comparison construction. In this work, we suggest to extend the procedure by the consideration of a hybrid survival function estimator that relies on an extreme value tail model through the Generalized Pareto distribution. We provide an estimator of treatment effect measures that notably improves on bias and remains easily apprehended for practical implementation. This is illustrated in an extensive simulation study as well as in an actual trial of a new cancer immunotherapy.     

The type I distribution of the ratio of independent “Weibullized” generalized beta-prime variables

In this paper we introduce the distribution of , with c >  0, where X _i , i =  1, 2, are independent generalized beta-prime-distributed random variables, and establish a closed form expression of its density. This distribution has as its limiting case the generalized beta type I distribution recently introduced by Nadarajah and Kotz (2004). Due to the presence of several parameters the density can take a wide variety of shapes.      

Followers and leaders: Reciprocity,social norms and group behavior

This paper proposes a model of norm-driven preferences and studies the determinants of norm compliance in games. It predicts that (i) compliance follows a law of demand and (ii) people respect norms in a reciprocal manner: they are more likely to comply if others are expected to comply too. Reciprocal norm compliance might explain why successful revolutions or strikes grow in a snow-balled fashion, leaders motivate others to join social movements, or sequential mechanisms (instead of simultaneous ones) are usually employed in charity fundraising.     

Retirement migration and transnationalism in northern Mexico

This article examines the phenomenon of transnationalism among retired immigrants living in border areas of northern Mexico. Using in-depth interviews conducted with US retirees residing in Baja California, Mexico, we seek to examine how transnational aging is constructed through different practices, relationships, networks and exchanges between both cultures and countries. We analyse several analytical dimensions of transnationalism including social, economic, cultural, identity and belonging conditions. In particular, networks and exchanges among these elderly migrants are most frequently constructed across social and family networks, economic transfers, access to healthcare, and culture. Additionally, we find that these maintained transnational practices in northern Mexico parallel those of international retired migrants living in other parts of the world. However, we argue that the proximity to the US border enables and encourages many types of connections of varying intensities. Finally, we discuss the implications for future research linking transnationalism with international retirement migration.
