This paper discusses the issue of possible reporting bias in media-based violent-event data and its relation to the role of communication technology in fostering collective action. We expand the work of Weidmann (2016), presenting several sensitivity analyses to determine the degree to which reporting bias may confound the relationship between communication technology and violence in a recent study that relies on event data for Africa. We find no strong evidence that suggests results on the positive relationship between communication technology and collective action in the study by Pierskalla and Hollenbach (2013) are wholly an artifact of reporting bias.

AbstractThe links between protests and state responses have taken on increased visibility in light of the Arab Spring movements. But we still have unanswered questions about the relationship between protest behaviors and responses by the state. We frame this in terms of concession and disruption costs. Costs are typically defined as government behaviors that impede dissidents’ capacity for collective action. We change this causal arrow and hypothesize how dissidents can generate costs that structure the government's response to a protest. By disaggregating costs along dimensions of concession and disruption we extend our understanding of protest behaviors and the conditions under which they are more (or less) effective. Utilizing a new cross-national protest-event data set, we test our theoretical expectations against protests from 1990 to 2014 and find that when protesters generate high concession costs, the state responds in a coercive manner. Conversely, high disruption costs encourage the state to accommodate demands. Our research provides substantial insights and inferences about the dynamics of government response to protest.

PurposeThe purpose of this paper is to establish the mediating role of collective action in the relationship between financial intermediation and financial inclusion of the poor in rural Uganda.Design/methodology/approachThe paper uses structural equation modeling (SEM) through bootstrap approach constructed using analysis of moment structures to test for the mediating role of collective action in the relationship between financial intermediation and financial inclusion of the poor in rural Uganda. Besides, the paper adopts Baron and Kenny’s (1986) approach to establish whether conditions for mediation by collective action exist.FindingsThe results revealed that collective action significantly mediates the relationship between financial intermediation and financial inclusion of the poor in rural Uganda. The findings further indicated that the mediated model had better model fit indices than the non-mediated model under SEM bootstrap. Furthermore, the results showed that both collective action and financial intermediation have significant and direct impacts on financial inclusion of the poor in rural Uganda. Therefore, the findings suggest that the presence of collective action boost financial intermediation for improved financial inclusion of the poor in rural Uganda.Research limitations/implicationsThe study used quantitative data collected through cross-sectional research design. Further studies through the use of interviews could be adopted in future. Methodologically, the study adopted use of SEM bootstrap approach to establish the mediating effect of collective action. However, it ignored the Sobel’s test and MedGraph methods. Future studies could adopt the use of alternative methods of Sobel’s test and MedGraph. Additionally, the study focused only on semi-formal financial institutions. Hence, further studies may consider the use of data collected from formal and informal institutions.Practical implicationsPolicy makers and managers of financial institutions should consider the role of collective action in promoting economic development, especially in developing countries. They should create structures and design financial services and products that promote collective action among the poor in rural Uganda.Originality/valueAlthough several scholars have articulated financial inclusion based on both the supply and demand side factors, this is the first study to test the mediating role of collective action in the relationship between financial intermediation and financial inclusion of the poor in rural Uganda using SEM bootstrap approach. Theoretically, the study combines the role of collective action with financial intermediation to promote financial inclusion. Financial intermediation theory ignores the role played by collective action in the intermediation process between the surplus and deficit units.

The relationship between community and class has largely been neglected. In this paper, this relationship is focused upon, and a model is developed which allows the identification of significant aspects of locality and class relationships. The model identifies three sets of relationships, those based on propinquity, those based on property, and those based on kinship, and argues that the basis of communion within a locality can be found within any one of these three main sets of relationships. The research which stimulated this paper started with a focus upon the relationship between space and class as expressed in the pattern of landownership. Working from this beginning point, the analysis moves to examine the nature of boundaries and the structure of local organisations which constitute ‘latent’ community. A further dimension, which was pivotal in many traditional rural community studies, is then explored, namely kinship. For each of these three sets of relationships, it is possible to identify objective patterns based upon boundaries and upon local organisation, property ownership, and kin connections. The process by which these objective relationships acquire subjective meaning is similar in each of the three cases. The possibility both of contradiction and of reinforcement therefore exists in the development of communion within localities. The conditions under which propinquity produces community through the development of subjective consciousness are then explored. In the conclusions a number of issues are highlighted which are brought into focus by this approach. These are the interconnections of community and class, the relationship between transience and social structure, and between male mateship and egalitarianism, the role of gender within communities, and, finally, the relationship between localities and the wider society.

ABSTRACTDaylight is the strongest synchronizer of human circadian rhythms. The circadian pathway hypothesis posits that synchrony between daylight and the circadian system relates to (in)attention. The dopamine neurotransmitter system is implicated in regulating the circadian system as well as in (attention)-deficit hyperactivity disorder [ADHD]. We studied the role of functional genetic variation in the gene encoding of dopamine-receptor-D4 (DRD4) in the relationship between inattention and seasonal daylight (changes). Gene-by-environment (GxE) mega-analyses were performed across eight studies including 3757 adult participants (with and without ADHD). We tested 1) theSpring-focus hypothesis, in which attention in 7R-carriers normalizes with increasing daylight levels preceding measurement, 2) theSummer-born ADHD hypothesis, in which 7R-carriers report more inattention when born in spring/summer than in autumn/winter, 3) theWinter-born ADHD hypothesis, opposing the second hypothesis. TheSpring-focus hypothesiswas upheld (1386 ADHD, 760 controls;d=-0.16 between periods); 7R-carriers reported evenlessinattention than 7R-non-carriers after winter solstice (d=0.27 between genotype-groups). Results were diagnosis-independent. Sensitivity analyses at individual study level confirmed the circannual patterns for 7R-carriers. Incorporating geographic changes into the independent measure, we also calculated changes in sunlight levels. This approach likewise showed that inattention correlated negatively with increasing light levels in 7R-carriers (r=-.135). Results emphasize peripheral effects of dopamine and the effects of (seasonal) daylight changes on cognition.

The continuous innovation and development of information technology and information infrastructure has driven the evolution of the supply form, and with the emergence of 5G, a mobile integrated communication system that includes communication access, interconnection, and connectivity of things, it has now evolved to a modern supply chain of the social organization collaborative type. This paper briefly describes the process of supply chain development, examines the role of communication technology in driving supply chain development, discusses the relationship between modern supply chain and social development and the support of 5G for modern supply chain, and illustrates the application of 5G in modern supply chain scenarios by reducing information time lag in market-side scenarios as an example.

The spread of cell phone technology across Africa has transforming effects on the economic and political sphere of the continent. In this paper, we investigate the impact of cell phone technology on violent collective action. We contend that the availability of cell phones as a communication technology allows political groups to overcome collective action problems more easily and improve in-group cooperation, and coordination. Utilizing novel, spatially disaggregated data on cell phone coverage and the location of organized violent events in Africa, we are able to show that the availability of cell phone coverage significantly and substantially increases the probability of violent conflict. Our findings hold across numerous different model specifications and robustness checks, including cross-sectional models, instrumental variable techniques, and panel data methods.

Conspiracy theories often concern political and milestone social events, mobilizing various explanations or actions. However, there is a still emerging research on how conspiracy theories mobilize normative and non-normative collective action, as well as political engagement. Furthermore, questions to be explored relate to emotional underpinnings of the consequential aspect of conspiracy theories. In our paper, we conducted two studies on exploring the relationship between exposure to conspiracy theories and normative, non-normative collective action and political engagement, moderated by primed victimhood and mediated by fear/anxiety and anger emotional indices. In two studies, we established the effect of exposure to conspiracy theories on normative, non-normative collection and political engagement, as well as the emotional valence following exposure to conspiracy or non-conspiracy scenarios. We also found a significant interaction between exposure to conspiracy theories and primed victimhood on normative, non-normative collective action and political engagement. Finally, fear/anxiety and anger indices mediated the moderation effect of the interaction between exposure to conspiracy theories and primed victimhood on the aforementioned dependent variables. Results are discussed in light of the broader impact of circulation of conspiracy theories and their effective tackle amidst societal traumas.

This article studies the role of international spillover of information and communication technology (ICT) in economic growth. We examine the performance of ten countries from 1982 to 1999. By empirically analyzing the relationship between total factor productivity (TFP) and domestic and foreign ICT investment with time series analysis tools, we find limited evidence that there exist international ICT spillovers for a group of countries. Further, we discuss the possible ICT policies to improve productivity and balance out a win-win situation for both ICT spillover sending and receiving countries.

We explored the mediating role of social adaptation in the relationship between mindfulness and cell phone dependence among college students. Data were obtained from 937 college students, who completed the Smartphone Addiction Inventory, the Adolescent Mindfulness Measure, and the Social Adaptation Questionnaire. The results suggest that mindfulness and social adaptation were significantly and negatively correlated with cell phone dependence, and that the mindfulness level of college students had a significant direct predictive effect on their cell phone dependence. We also found a significant mediating effect of social adaptation in the relationship between mindfulness and cell phone dependence. These findings are of significance to the prevention of and intervention in young people's cell phone dependence.
