The Role of Gay Identity Confusion and Outness in Sex-Seeking on Mobile Dating Apps Among Men Who Have Sex With Men: A Conditional Process Analysis

Mobile dating apps are now a popular platform for men who have sex with men (MSM) to connect with others. Based on the uses and gratifications (U&G) theory, this study explores the relationship between sex-seeking and the number of casual sex partners met through MSM-based mobile dating apps (Grindr, Jack’d, and SCRUFF). The conditional process analysis (N = 401) shows that this relationship was significant and was mediated by the intensity of app use. That is, sex-seeking indirectly affected the number of casual sex partners through the intensity of app use. Furthermore, gay identity confusion and outness to the world moderated this indirect effect: it was stronger when the user was either more confused about his sexuality or was less out to the world. This research introduces an alternative way to incorporate psychographics variables into the U&G framework.     

Global culture,learning style,and outcome: an interdisciplinary empirical study of international university students

The study examined 2500 business degree students from 21 countries, enrolled at an Australian university, using a survey to assess learning style, which was integrated into a global culture taxonomy. The research hypothesis was that academic outcome could be explained through an interdisciplinary model, by integrating proven theories from educational psychology (learning style) and anthropology (culture). The literature review included interdisciplinary and rival theories to make the research useful for global practitioners. Technical discussion was minimized, focusing on the pedagogical implications of a generalized least squares regression model, which was statistically significant (r ² = 0.87; X ² = 0, df = 0, p < 0.0001; n = 715). Four factors dominated the model in predicting higher multicultural student academic outcome: collectivist and risk‐taking cultures, along with visual‐input and active‐processing learning styles.

La recherche a été hypothèse que études résultat pourrait être expliqué par le biais d’un modèle interdisciplinaire, en intégrant les théories éprouvées de psychologie de l’éducation (style d’apprentissage) et de l’anthropologie (la culture). La revue de la littérature inclus interdisciplinaire et théories rivales à faire de la recherche utiles pour les praticiens mondial. Discussion technique a été réduit au minimum, axée sur les implications pédagogiques d’un généralisée des moindres carrés modèle de régression, qui a été statistiquement significative (r ² = 0.87; X ² = 0, df = 0, p < 0.0001; n = 715). Quatre facteurs dominent le modèle supérieur à la prévision multiculturelle des étudiants universitaires résultat: collectiviste et de prendre des risques cultures, ainsi que les visuels d’entrée et de processus actif styles d’apprentissage.

社会企业概念探析——欧美地区比较视角

社会企业于20世纪80年代兴起于欧美国家,掀起了一股学术与实践热潮。文章从欧美地区比较视角切入,探析了欧美地区不同发展背景下社会企业的概念与内涵。欧美地区社会企业概念差异来自于不同的发展背景:由于美国非营利组织商业化传统和欧洲地区的福利国家危机,因而欧洲和美国学术界与实践界对于社会企业的概念界定也相应不同;美国社会企业从企业社会慈善到社会目的企业的社会企业光谱,而欧洲社会企业更强调社会经济传统下的具有民主参与特点的社会企业。

Transition and Foreign Aid Policies in the Visegrád Countries: A Path Dependant Approach

The paper argues that the current emerging international development policies of the Visegrád (V4) countries are heavily influenced by the certain aspects of the Communist past and the transition process. Due to these influences, the V4 countries have difficulties in adapting the foreign aid practices of Western donors and this leads to the emergence of a unique Central and Eastern European development cooperation model. As an analytical background, the paper builds on the path dependency theory of transition. A certain degree of path dependence is clearly visible in V4 foreign aid policies, and the paper analyses some aspects of this phenomenon: how these new emerging foreign aid donors select their partner countries, how much they spend on aid, how they formulate their aid delivery policies and institutions and what role the non-state actors play. The main conclusions of the paper are that the legacies of the Communist past have a clear influence and the V4 countries still have a long way to go in adapting their aid policies to international requirements.

CROSSING TEHRAN AVENUE

The online city magazine TehranAvenue.com (TA) occupies the transnational crossroad of digital and urban space. It thus provides an important case study of how urban studies, postcolonial theory and critical cyber studies can be combined fruitfully to explain the potentialities and limits of digital and social networks in transnational Middle Eastern contexts. The article explores metaphors of the Internet as city, theories of transnational urban space and recent studies of the Internet and its politico-cultural uses in Iran to establish a theoretical method that can explain the simultaneity of local and transnational in digital and urban spaces. Qualitative data (email and telephone interviews with TA's founder, editor and contributors), combined with content analysis of the site, supports the claim that the city as metaphor and metonym can account for the intersection between contemporary North African and Middle Eastern digital spaces and national and diasporic urban spaces. The digital city – or blogabad – expands physical urban space into transnational networks. But there are important limits to the transnational reach of mediated social networking practices. In fact, the located identifications of web users are often much more important than the global reach of the technologies they use.     

Likelihood‐based and marginal inference methods for recurrent event data with covariate measurement error

Recurrent event data arise commonly in medical and public health studies. The analysis of such data has received extensive research attention and various methods have been developed in the literature. Depending on the focus of scientific interest, the methods may be broadly classified as intensity‐based counting process methods, mean function‐based estimating equation methods, and the analysis of times to events or times between events. These methods and models cover a wide variety of practical applications. However, there is a critical assumption underlying those methods–variables need to be correctly measured. Unfortunately, this assumption is frequently violated in practice. It is quite common that some covariates are subject to measurement error. It is well known that covariate measurement error can substantially distort inference results if it is not properly taken into account. In the literature, there has been extensive research concerning measurement error problems in various settings. However, with recurrent events, there is little discussion on this topic. It is the objective of this paper to address this important issue. In this paper, we develop inferential methods which account for measurement error in covariates for models with multiplicative intensity functions or rate functions. Both likelihood‐based inference and robust inference based on estimating equations are discussed. The Canadian Journal of Statistics 40: 530–549; 2012 © 2012 Statistical Society of Canada     

Bivariate censored regression relying on a new estimator of the joint distribution function

In this paper we study a class of M  -estimators in a regression model under bivariate random censoring and provide a set of sufficient conditions that ensure asymptotic n^1/2-convergence$n^{1/2}\mathrm{-}\mathrm{convergence}$. The cornerstone of our approach is a new estimator of the joint distribution function of the censored lifetimes. A copula approach is used to modelize the dependence structure between the bivariate censoring times. The resulting estimators present the advantage of being easily computable. A simulation study enlighten the finite sample behavior of this technique.
