Gender inequality in mobile technology access: the role of economic and social development*

ABSTRACT

Digital inequality is a burgeoning field of study across disciplines, yet few papers address categorical digital inequality in cross-national samples. Using the only available cross-national data on access to Information and Communications Technologies (ICTs) disaggregated by gender from the International Telecommunications Union (ITU), I add to existing literature by examining factors associated with women’s unequal access to mobile phones across 51 countries. The largest of such samples, the ITU data demonstrates that the type and levels of gender inequality in mobile phone use are not consistent throughout countries. In fact, the distribution is quite variable, from incorporating a small-sample of nations where women have marginally higher access, to sub-samples close to parity, to a larger sub-sample where women are at a substantial disadvantage. Using Quantile Regression Methods to assess these variations, I test how major gender and international development theories inform inequality patterns. My findings suggest that women’s wellbeing, as measured by their access to modern contraception (i.e., reproductive autonomy), overwhelmingly promotes women’s relative access to mobile phones, regardless of preexisting levels of access. Other perspectives like the growth imperative and world polity theory show some staggered associations along the distribution that remain substantively inconclusive.     

Rising powers,people rising: neo-liberalization and its discontents in the BRICS countries

ABSTRACT

The rise of the BRICS countries – Brazil, Russia, China, India, and South Africa – has called into question the future of Western dominance in world markets and geopolitics. However, the developmental trajectories of the BRICS countries are shot through with socio-economic fault lines that relegate large numbers of people to the margins of current growth processes, where life is characterized by multiple and overlapping vulnerabilities. These socio-economic fault lines have, in turn, given rise to political convulsions across the BRICS countries, ranging from single-issue protests to sustained social movements oriented towards structural transformation. This article presents an innovative theoretical framework for theorizing the emerging political economy of development in the BRICS countries centred on neo-liberalization, precarity, and popular struggles. It discusses the contributions to this special issue in terms of how they illuminate the intersection between neo-liberalization, precarity, and popular struggle in Brazil, Russia, India, China, and South Africa.     

The emotional costs of computers: an expectancy-value theory analysis of predominantly low-socioeconomic status minority students’ STEM attitudes

There is a strong push to increase American students’ interest in Science, Technology, Engineering, and Mathematic (STEM) careers. However, minority and female students remain underrepresented in the STEM fields. Therefore, it is essential that we continue to examine the potential factors that both incite and dissuade STEM interest. We apply Expectancy-Value Theory (EVT) to examine STEM attitudes of predominantly low-socioeconomic status minority elementary school students over the course of a computing intervention. Furthermore, we integrate the digital inequality mental access conceptualization of ‘emotional costs’ into the EVT model in order to predict students’ negative STEM attitudes. Data are from a large-scale computing intervention that took place in a primarily minority, high poverty, urban elementary school district located in the southeastern USA. Results indicate that positive expectancies for success and subjective task values predict students’ positive STEM attitudes. Emotional costs toward technology primarily predict negative STEM attitudes. Students’ expectancies/values and emotional costs may have a ‘push-and-pull’ effect on the formation of STEM attitudes. This study successfully links digital disparities to STEM disparities by integrating the digital inequality concept of emotional costs. Practically, we conclude that future computing interventions should increase students’ academic-related expectancies and values while also minimizing their emotional costs in order to address both digital and STEM inequalities. Theoretically, we conclude that broad conceptualizations of emotional costs should be included in future studies to help explain negative attitudes/motivations toward STEM-related topics.     

对外直接投资对母国收入差距的影响效应——基于跨国面板数据的研究

本文将企业异质性理论引入内生增长模型，讨论对外直接投资（OFDI）对母国收入差距的影响机理，并基于1981~2015年85个国家（地区）的面板数据，同时运用静态模型与动态模型验证了二者间存在"倒U型"关系，即随着对外直接投资强度的提升，母国收入差距呈现先扩大再缩小的态势；OFDI一方面通过促进母国的技术进步与产业结构升级、挤出部分国内投资等渠道加剧了收入不平等程度，另一方面以推动母国的金融发展与教育拓展等方式对收入差距产生削减效果；OFDI对收入差距的影响在不同经济发展水平、不同地理区位的国家中具有异质性：当人均GDP小于5767.53美元时，对外直接投资强度显著地扩大了母国收入差距，当人均GDP超过5767.53美元时，二者之间不存在显著的线性关系；欧洲国家的OFDI与收入差距之间呈现出"倒U型"关系，美洲、亚洲国家的OFDI促进了母国收入差距的扩大，非洲国家的OFDI对收入差距无显著影响；此外，OFDI对母国收入差距的影响具有跨期效应，随着时间推移与OFDI存量增加，其间接效应的边际效果有所减弱。     

The speed of life and death: migrant fatalities,territorial boundaries,and energy consumption

This article considers how migrant deaths – particularly in the borderlands of Europe and the United States – relate to the speed at which migrants travel. It argues that the most dangerous boundaries for migrants, and the most difficult ones to traverse, are those which embody the sharpest divides in energy consumption, divides reflected in the vulnerability of migrants who typically move at relatively slow speeds and have insufficient access to safe modes of travel. Thus, migrant deaths and the boundaries that produce them embody the injustices associated with grossly unequal levels of access to, control over, and consumption of environmental resources.     

Culture,Region, and Cross‐National Violent Crime

Past cross‐national crime research has focused on structural factors with considerably less attention paid to cultural predictors. We extend the culture of honor thesis by identifying the importance of cultural gender inequality and test a direct measure of it on cross‐national violent crime rates. While prior research typically uses regional variables as proxies for culture, by using a direct cultural measure we are also able to identify whether culture contributes to explaining the regional associations found previously. Based on national surveys of 153 nations and more than a million respondents, this study is able to explore cultural, structural, and regional predictors of violent crime rates cross‐nationally. Two regions, Latin America and sub‐Saharan Africa, are far above the rest of the world in terms of violent crime rates. It turns out that most of the standard structural variables found to be important in previous cross‐national studies no longer have significant effects when controls for these two regions are imposed. On the other hand, we find that our measure of cultural gender inequality has one of the largest associations with violent crime rates, net of region, and also explains portions of both regional associations.     

The microfinance promise—can it be kept? A macro perspective

After five decades of rapid expansion of microfinance worldwide, little is known about its aggregate effects and whether the “microfinance promise” of poverty reduction holds at the macro level. Challenging questions have arisen. Here we explore the dynamic response of microfinance on economic growth, financial deepening and income inequality. Countries are grouped into three broad clusters (stable, moderate and poor) based on macro‐institutional variables. Our results show that microfinance has a significant long‐term ability to affect the broader economy. However, the impact and dynamics of microfinance differ substantially across macro‐institutional environments. It grows in weaker environments, reaches its peak in developing economies, and then gradually “dies out” in more stable economies. While there is evidence of a positive impact of microfinance at the aggregate level, the response is different depending on whether countries are poor, moderately developed or economically stable. Once countries climb up the macro‐institutional “ladder,” microfinance can take a different shape and its relationship with other macroeconomic fundamentals can change. Our results indicate that microfinance has the strongest effect when the external environment is supportive and proactive; in weak environments, microfinance cannot grow sufficiently. Therefore, more attention should be given to supporting the socioeconomic dimensions of economies.

Convergence properties of the EM algorithm in constrained parameter spaces

The established general results on convergence properties of the EM algorithm require the sequence of EM parameter estimates to fall in the interior of the parameter space over which the likelihood is being maximized. This paper presents convergence properties of the EM sequence of likelihood values and parameter estimates in constrained parameter spaces for which the sequence of EM parameter estimates may converge to the boundary of the constrained parameter space contained in the interior of the unconstrained parameter space. Examples of the behavior of the EM algorithm applied to such parameter spaces are presented.
