The article aims to contribute to the still relatively unexplored area of the relationship between gender and online political participation. Using two complementary methods – a representative, post-election survey of the adult Czech population and a content analysis of communication on the selected Czech political parties’ Facebook profiles during the campaign for the 2013 Parliamentary Elections – we attempt to challenge some established assumptions regarding the allegedly equalizing effect of the Internet and social media on participatory behaviour of men and women. While survey data discovered subtle yet statistically significant differences between men and women in some online expressive activities on Facebook, mainly commenting on other users’ statuses, content analysis further revealed that there are not only notable gender gaps among the Facebook users who commented on the campaign, but also differences in the tone of communication produced by the respective gender groups, with men posting more negative comments addressed to parties as well as to other Facebook users. We suggest that these results question the prevailing perception about the narrowing of the ‘gender gap’ in the online environment and call for a more nuanced methodological approach to different forms of online political expression.  相似文献

Mitochondrial defects have been related to obesity and prostate cancer. We investigated if Mexican–Mestizo men presenting this type of cancer, exhibited somatic mutations of ATP6 and/or ND3.Body mass index (BMI) was determined; the degree of prostate cancer aggressiveness was demarcated by the Gleason score. DNA from tumor tissue and from blood leukocytes was amplified by the polymerase chain reaction and ATP6 and ND3 were sequenced. We included 77 men: 20 had normal BMI, 38 were overweight and 19 had obesity; ages ranged from 52 to 83. After sequencing ATP6 and ND3, from DNA obtained from leukocytes and tumor tissue, we did not find any somatic mutations. All changes observed, in both genes, were polymorphisms. In ATP6 we identified, in six patients, two non-synonymous nucleotide changes and in ND3 we observed that twelve patients presented non-synonymous polymorphisms. To our knowledge, this constitutes the first report where the complete sequences of the ATP6 and ND3 have been analyzed in Mexican–Mestizo men with prostate cancer and diverse BMI. Our results differ with those reported in Caucasian populations, possibly due to ethnic differences.  相似文献

The purpose of this article is to deepen the understanding of the impact of the social and economic crisis on homeless people in Spain. To this end we present the results of research carried out prior to the crisis and later updated in the midst of the economic recession, underscoring the main results obtained in both periods and tracing their evolution. The number of homeless people in Spain has risen as a result of the crisis. Moreover, while some characteristics of this group remain the same, others have changed. Hence, difficulties in access to the labour market and cuts in certain economic benefits are resulting in an increase in the duration of social inclusion processes. This results in a worsening of the personal situation of the homeless, especially in relation to mental illness and substance abuse. The immigrant population is the group most affected by these impacts. The situation clearly demonstrates the need to reflect on how to deal with the problem of homelessness in Spain, and to rethink the way professionals intervene, especially during periods of economic recession.  相似文献

During the last 20 years, the influx of immigrant pupils in Spanish schools has taken up much of school counsellors’ agendas. This leads us to reflect upon the status and role of educational guidance in terms of cultural diversity management, particularly focusing on two elements that may potentially help understand the situation: relations with other educational agents and the intervention model applied. The field work for this study was carried out during an academic semester in four secondary schools in Huelva. In addition to the analysis of official school documentation, remarks and field notes, semi-structured interviews were carried out and a discussion group was held with the four counsellors. Counsellors are trying to overcome an intervention model that is mainly therapeutic in nature and make space in their schedules for a way of working that is more focused on prevention and advisory services, incorporating the participation of other educational actors. But this is not an easy task. The possibility of generating changes would encourage better integration of cultural diversity in the life of schools, rather than treating it as a negative/deficit view, as an occasional issue, individual and isolated from the sum of school activities and other members of the education community.  相似文献

This study investigated co-morbidity of problem gambling and problematic Internet use (PIU) among adolescent Internet and land-based gamblers, with the classic approach using sum-scores of symptoms and a promising new method, namely the network perspective. This perspective allows testing for how multiple disorders are associated, showing symptoms overlap and centralities. We used cross-sectional data from two population-based samples of adolescents aged 17 years in France (n = 2,240) and Switzerland (n = 944). Measures included Internet gambling, problem gambling and PIU. The classic approach showed that Internet gambling was associated with increased levels of disordered gambling and PIU, but that correlations between disorders were weak (R2 min = 3.2%, R2 max = 17.6%). The network perspective showed that the co-morbid network of Internet gamblers was more connected in comparison with land-based gamblers. Problem gambling and PIU appeared as separate disorders, but their relationship was increased among Internet gamblers in comparison with land-based gamblers. The network perspective appeared as a promising avenue for a better understanding of addictive disorders, but it should not replace the classic approach, which showed increased levels of addictive behaviours among Internet gamblers.  相似文献

We give attention to the racial contexts of mathematics education in Colombia and the USA. We discuss the particularities of these contexts but also explore the how in both contexts Blackness and Black people are relegated to the lower rungs of the social order. In offering this comparative analysis, we call for expanded research on race, racism, and mathematics education in global contexts.  相似文献

In this study the relationship between obesity, alcohol misuse, smoking and changes in quantity of labor supplied during an economic meltdown are examined. The data used stem from a health and lifestyle panel survey carried out by the Public Health Institute of Iceland in 2007 and 2009. Probit analysis was used to assess if pre-crisis body weight, alcohol misuse or smoking were related to subsequent job-loss or a reduction in hours worked following the 2008 economic collapse in Iceland. Results indicated that body weight, alcohol misuse and smoking are related to reductions in quantity of labor supplied for females only. Female body mass index was positively related to the probability of a reduction in quantity of labor supplied, while alcohol misuse and smoking were negatively related to the probability of decreasing hours worked for females.  相似文献

The article evaluates the perceptions of Jewish power among the Czechoslovak exiles in Britain during the Second World War. The analysis documents the apparent persistence of prejudices against the Jewish minority among the Czechoslovak non-Jewish authorities that eventually formed the government-in-exile (1940–5), under the presidency of Edvard Bene? (1884–1948). The Czechoslovak exiles believed that the Jewish minority, in particular the Jewish nationalists (Zionists), had vehement supporters within Jewish circles in Western countries. Furthermore, they believed that the Jewish press played a significant role in the formation of public opinion in Britain and especially in the United States. In the early 1940s, the government-in-exile embarked on a policy of national homogenisation of post-war Czechoslovakia and was anxious to give concessions to the political representatives of the ethnic minority groups in exile, in particular the Germans, Hungarians and Jews. Yet the concerns about Jewish influence in liberal democracies granted several political concessions to the Jewish minority, in particular the appointment of a Zionist representative, Arno?t Frischer (1887–1954), to the exile parliament. This notwithstanding, by analysing the internal situation among the Czechoslovak Jewish groups in London, the article documents the internal weakness and disputes among the Jewish groups which gradually revealed the utter powerlessness of the Jewish exiles during their negotiations with the Czechoslovak authorities. The Jewish groups (the assimilationists, Orthodox and secular nationalists) were divided by mutual as well as internal disputes which were not concealed from outside observers and were utilised by the exile government. What emerges from the analysis is an impression of quarrelling groups that could not agree on any of the fundamental issues and whose only power was the ability to court the support of Western Jewish groups, which were perceived by the non-Jewish exiles as influential actors in US and British society.  相似文献

Over the last two decades, research on unauthorized migration has departed from the equation of migrant illegality with absolute exclusion, emphasizing that formal exclusion typically results in subordinate inclusion. Irregular migrants integrate through informal support networks, the underground economy, and political activities. But they also incorporate into formal institutions, through policy divergence between levels of government, bureaucratic sabotage, or fraud. The incorporation of undocumented migrants involves not so much invisibility as camouflage – presenting the paradox that camouflage improves with integration. As it reaches the formal level of claims and procedures, legalization brings up the issue of the frames through which legal deservingness is asserted. Looking at the moral economy embedded in claims and programs, we examine a series of frame tensions: between universal and particular claims to legal status, between legalization based on vulnerability and that based on civic performance, between economic and cultural deservingness, and between the policy level and individual subjectivity. We show that restrictionist governments face a dilemma when their constructions of “good citizenship” threaten to extend to “deserving” undocumented migrants. Hence, they may simultaneously emphasize deservingness frames while limiting irregular migrants’ opportunities to deserve, effectively making deservingness both a civic obligation and a civic privilege.  相似文献

This systematic review summarizes the relatively scant literature concerning the effectiveness of water-based exercise (WBE) interventions in people with Parkinson’s disease (PD). Databases MEDLINE, EMBASE, PEDro, Scopus, and SportDiscus were searched from the earliest available date to December 2011. Studies had to meet the following selection criteria: (1) the target population was patients with PD; (2) the effects of a WBE intervention (as the primary intervention) were tested; (3) the abstract of the research was available in English. Selected studies were subject to unmasked quality assessment by applying a methodological scoring with a possible maximum score of 15 points. Twelve studies met the inclusion criteria, although only three of them achieved a methodological quality score above 10 points. Collectively, the data showed that WBE has some beneficial short-term effects on the impact that PD has on the patients (mainly on their motor symptoms and on their functional mobility), as well as on their quality of life. This review provides evidence that WBE is safe for patients with PD, but there is a lack of hard evidence regarding its beneficial effects. Further randomized and controlled trials with larger sample sizes are required.  相似文献
