Governance,credit access and clean cooking technologies in Sub-Saharan Africa: Implications for energy transition

There is a global effort toward reducing or eliminating dirty fuels and technologies for cooking due to their severe health, environmental and economic implications. Reducing dirty energy usage requires an effective transition toward clean fuels and technologies for cooking. Effective governance and financial systems are needed to hasten the transition toward clean fuels and technologies for cooking. However, not much is known empirically about the role of access to credit and governance in the transition towards clean cooking technologies, especially in sub-Saharan Africa (SSA). This study, therefore, utilizes the two-step-dynamic system generalized method of moment estimator to investigate the effect of access to credit and governance on the adoption of clean cooking technologies in SSA. The findings indicate that access to credit and governance variables do not facilitate clean cooking technologies usage. The conditional analysis also reveals that the governance variables moderate the effect of access to credit to impede the adoption of clean fuels and technologies for cooking. The findings indicate that economic growth, education, and rural population drive the adoption of clean cooking technologies. Sensitivity checks show that the effect of access to credit and governance on clean fuels and cooking technologies usage differs among income and regional groups within SSA. We, therefore, argue that better financial and governance systems are required to hasten the transition toward clean fuels and technologies for cooking in SSA.     

From ‘moments of madness’ to ‘the politics of mundanity’ - researching digital media and contentious collective actions in China

Abstract

Information and communication technologies (ICTs) have become an essential part of contentious politics and social movements in contemporary China. Although quite a few scholars have explored ICTs, contentious politics, and collective action in China, they largely focus on the event-based analysis of discrete contentious events, failing to capture, reflect, and assess most of the political ferment in and around the routine use of digital media in people’s everyday lives. This study proposes a broader research agenda by shifting the focus from contentious events – ‘moments of madness’ – to ‘the politics of mundanity’: the political dynamics in the mundanity of digitally mediated, routine daily life. The agenda includes, first, the investigation of the dynamics underlying the mundane use of digital media, which not only places the use of ICTs in contentious moments into ‘a big picture’ to understand the political potential of mundane use of ICTs, but also reveals ‘everyday resistance,’ or less publicly conspicuous tactics, as precursors of open, confrontational forms of contentious activity. Second, the agenda proposes the examination of mundane experiences to understand the sudden outburst of contention and digital media as the ‘repertoire of contention.’ Third, the agenda scrutinizes the adoption of mundane expressions of contentious challenges to authoritarian regimes, as they allow for the circumvention of the heavy censorship of collective action mobilization. Mundane expressions have thereby emerged as a prominent part of the mobilization mechanism of contention in China. Addressing ‘the politics of mundanity’ will provide a nuanced understanding of ICTs and contentious collective action in China.     

The organization of diversity in a boxing club: Governmentality and entangled rationalities

This study answers a recent call for research on the complexity, locality, and use of power in the governing of diversity in organizations. We used the concepts of governmentally and of governing sameness and difference to explore multiple and heterogeneous ways of regulating gender diversity in organizations. Governmentally was defined as interrelated ways of reasoning and of using technologies of power within a boxing organization. We found that in their management of the full participation of women, participants used both sport and gender rationalities, each of which relied on different technologies of power in specific settings. Ambiguous meanings were strategically used to manage the participation of women in boxing and to maintain heroic masculine practices.     

Foresight Study on the Risk Governance of New Technologies: The Case of Nanotechnology

Technology‐led innovation represents an important driver of European economic and industrial competitiveness and offers solutions to societal challenges. In order to facilitate responsible innovation and public acceptance, a need exists to identify and implement oversight approaches focused on the effective risk governance of emerging technologies. This article describes a foresight study on the governance of new technologies, using nanotechnology as a case example. Following a mapping of the governance landscape, four plausible foresight scenarios were developed, capturing critical uncertainties for nanotechnology governance. Key governance elements were then stress tested within these scenarios to see how well they might perform in a range of possible futures and to inform identification of the strengths, weaknesses, opportunities, and threats for nanotechnology governance in Europe. Based on the study outcomes, recommendations are proposed regarding the development of governance associated with the responsible development of new technologies.

大学英语教学中多媒体技术的应用模式研究

多媒体技术应用于大学英语教学适合目前大学英语教学的现状。通过对比试验研究,将多媒体技术与传统课堂教学进行有机结合的教学效果明显优于单独采用传统课堂教学或多媒体教学,这样有利于学生听力理解水平的提高,而传统课堂教学对学生词汇语法的掌握更有利,理想的方式是二者的有机结合。     

Stemming the downturn: How ambidexterity and public policy influence firm performance stability during economic crises

A key question confronting policy makers during economic crises is how they can support firms to maintain their performance levels until the economic storm has passed. The present study bridges insights from the ambidexterity and public policy literatures to examine how firm-internal responses (that is, ambidexterity) and external public policy incentives (that is, demand-pull policies) affect the stability of firms’ performance in a recessionary economic context. Using data from private German renewable energy firms at a time following the global financial crisis, we find that only firms with low ambidexterity achieve performance stability in light of demand-pull policies. This research draws attention to the relevance of stability as a policy-relevant performance measure during times of economic crises. Further, we suggest that greater insight into the interplay of managerial and political factors is necessary to enable policy makers to support the stability of certain industries during crises.     

Government cuts to Disabled Students’ Allowances must be resisted

Cuts to essential grant funding for disabled students in England will put disabled students’ studies at risk. Proposed cuts to Disabled Students’ Allowances (DSAs) in 2015 will redefine disability and damage the validity of equality indicators. As a result, the needs of many disabled students may be systematically overlooked, leading to unequal outcomes for students, academia and wider society.
