ABSTRACT

Developments in the area of ‘precision agriculture’ are creating new data points (about flows, soils, pests, climate) that agricultural technology providers ‘grab’, aggregate, compute and/or sell. Food producers now churn out food and, increasingly, data. ‘Land grabs’ on the horizon in the global south are bound up with the dynamics of data grabbing, although hitherto researchers have not revealed enough about the people and projects at issue. Against this backdrop, this paper examines some key issues taking shape, while highlighting new frontiers for research and introducing the concept ‘data sovereignty’, which food sovereignty practitioners (and others) need to begin considering.  相似文献

This article explores the ethnic incorporation of Irish women on the West Coast of New Zealand’s South Island from 1864, when the gold rushes began, until the formation of the Irish Free State in 1922. The central argument is that these newcomers did not choose ethnic solidarity as a means to pursue their goals and, for most, an ethnic or religious category sufficed in an environment where local communities, churches, trade unions, kinship ties and non‐ethnic political parties had far more social relevance. The small‐scale structure of West Coast localities, the relative economic homogeneity of its inhabitants and the absence of entrenched anti‐Irish elites militated against the rise of sectarian animosities and the maturation of intensified ethnic consciousness. As a consequence, Irish women did not construct and sustain informal social networks based on ‘principles of ethnic categorisation’ in which they distributed resources and channelled interaction among group members.  相似文献

Exposure to media violence, including violent video gaming, can have a cognitive desensitization effect, lowering empathic concern for others in need. Since emerging adulthood offers increased opportunities to volunteer, strengthen relationships, and initiate new relationships, decreases in empathic concern and prosocial behavior may prove inhibitive to optimal development during this time. For these reasons, the current study investigated associations between violent video gaming, empathic responding, and prosocial behavior enacted toward strangers, friends, and family members. Participants consisted of 780 emerging adults (M age = 19.60, SD = 1.86, range = 18–29, 69% female, 69% Caucasian) from four universities in the United States. Results showed small to moderate effects between playing violent video gaming and lowered empathic concern for both males and females. In addition, lowered empathic concern partially mediated the pathways between violent video gaming and prosocial behavior toward all three targets (at the level of a trend for females), but was most strongly associated with lower prosocial behavior toward strangers. Discussion highlights how violent video gaming is associated with lower levels of prosocial behavior through the mechanism of decreased empathic concern, how this association can affect prosocial behavior differently across target, and finally what implications this might have for development during emerging adulthood.  相似文献

The issue of ‘alcohol-fuelled violence’ has been the subject of intense policy debate in Australia. While this debate is warranted, its contours and content have been informed and shaped by a surprisingly narrow range of research resources. Narrow research engagements of this kind warrant scrutiny because they can exclude from consideration crucial issues. In this article we identify one such issue, that of gender. Following a review of the Australian literature on gender, alcohol and violence, our analysis explores four case studies drawn from the Australian research corpus, focusing on large quantitative studies as these tend to receive most attention and citation in policy debate. Such studies consistently erase the contribution of key gender dynamics, namely enactments of particular (often youthful) masculinities, to violence involving alcohol, even where they simultaneously provide strong support in their data for such a conclusion. We show how this research is mobilised specifically in support of claims about the causal role of alcohol in violence and of blanket population-level responses to the problem. There is an urgent need to map the character and scope of the tendency to erase certain gender issues in research on alcohol and violence in order to better inform policy responses.  相似文献

The Islamic State’s conquest of swathes of Iraqi territory, combined with falling oil prices, revealed the fault lines of a model of economic development that made the country extremely vulnerable to the events of 2014. Over the last 13 years, the consolidation of the rentier economy in parallel to the promotion of a neoliberal model – a neoliberal rentier system – has not initiated a process of sustainable economic development. The main factors explaining this missed opportunity can be found in the tensions that exist between the two models and, in particular, between the relative roles of the state and the private sector as drivers of economic development.  相似文献

This article focuses on the radical right's influence on immigration and migrant integration policy by scrutinising the 6-year period in national government of the Austrian Freedom Party and Alliance for Austria's Future. Specifically, it investigates the radical right's influence on migration control, migrant integration, citizenship and asylum policy. While previous studies have often credited the Austrian radical right with policy influence, it is argued that such work ignores both the problematic adjustment of the radical right to public office and the insights of immigration policy theory. By integrating these criticisms into the analysis, it is argued that although immigration policy was restrictive, the policies pursued did not deviate too greatly from past and subsequent government policy nor with the policies being implemented elsewhere in Europe. Furthermore, the radical right's influence on immigration policy was limited by the role of intra-coalition dynamics and the moderating effect of the policy process.  相似文献

The objective of the study was to examine the association between disturbed sleep and the functioning of adolescents, in particular cumulative effects on functioning across multiple life domains. Data from a large, school-based survey (n = 5,423) were used to examine the association between eight indicators of psychological, interpersonal, and somatic functioning and symptoms of insomnia and hypersomnia among adolescents. The strongest correlates of insomnia were disturbed mood (OR = 5.9), fatigue (OR = 7.4), and suicidal ideation (OR = 3.4). The same pattern held for hypersomnia, although the associations were not as strong for fatigue (OR = 6.8), mood disturbance (OR = 3.5), and suicide ideation (OR = 2.8). Youths who experienced both insomnia and hypersomnia had greater odds of psychological, interpersonal, and somatic dysfunction than youths who had experienced only one sleep disturbance. Cumulative effects of sleep problems were pronounced, with 27.6% of those with hypersomnia, 41.7% of those with insomnia, and 59.2% of those with both sleep problems reporting three or more types of dysfunction. The results suggest that adolescents experiencing disturbed sleep also experience a range of deficits in functioning. Further, youths with disturbed sleep are more likely to manifest multiple deficits in functioning. From the available evidence, however, it is not possible to specify what the causal pathways are. What are needed are cohort studies designed to examine the association of disturbed sleep and functional impairment among adolescents prospectively.  相似文献
