This contribution focuses on the territorial relationships established by companies of Argentinian origin that have extended their scope of action to other MERCOSUR countries (mainly Brazil) in the first stages of the soybean chain. Although some features of grain production and particularly of soybean enable a temporary commitment of these firms with local spaces, they develop some kind of foundations as a necessary condition to operate. A relevant side of their forms of territorial embeddedness is the strong selectiveness of local spaces and actors promoted by their behavior. Some local actors are in fact included; in the long term, however, their capacity to capture value is constrained since they are not able to control the terms and conditions of their incorporation. 相似文献

This article examines to what extent transparency is a condition for the creation of public value. Transparency is usually narrowly defined as a tool for external stakeholders to monitor the internal workings of an organization, but public value management positions transparency as a broader instrument for actively engaging stakeholders. We investigate empirically whether transparency is indeed necessary to create public value, distinguishing between transparency about operational capacity, authorizing environment, and value proposition. We find that more transparent public organizations achieved higher public value scores, especially if they disclosed information about the design and dynamics of their authorizing environment. 相似文献

This study is the first to examine the background level of male DNA on underpants worn by females in the absence of sexual contact. Here, we examined 103 samples from the inside front of underpants from 85 female volunteers. Samples were examined for the presence of male DNA using NGM SElect and PowerPlex Y23 kits. Only five samples gave a “complete” Y-STR profile, even though 83.5% of our volunteers cohabited with a male. In all cases where a partner reference sample was available, the Y-STR profile matched the cohabiting partner. We have demonstrated that a Y-STR profile is not expected on the inside front of underpants worn by females after social contact alone. The results of this study are informative for evaluating the significance of a Y-STR profile on underpants in cases of alleged sexual assault. 相似文献

In recent years, the Civil Society Education Fund has supported national education civil society coalitions (NECs) in low-income countries so that they put pressure on governments and donors to implement the Education for All agenda and the Millennium Development Goal on education. This article draws on literature on global governance as well as on an extensive evaluation of the CSEF to explore the actual contribution of this initiative to the activity of NECs. The article highlights the achievements and shortcomings of the CSEF and includes a set of practical recommendations on the role of global civil society in international development processes. 相似文献

The level of degradation of DNA as a means for determining the time of death has been proposed as a valid adjunct to the classic thanatochronologic methods. The twofold aim of this work was to determine which organ might reveal both a correlation between the percentage of degradation of the DNA and the time lapse since death, and would be easiest to sample and yield the most reproducible results even in technically unfavorable situations such as on-the-spot investigations at the scene of death. A comparison of the spleen, blood, and liver showed that hepatic tissue best meets these specific needs because it shows a virtually linear correlation between the time elapsed since death and the level of degradation of the DNA, and it can easily be sampled at the scene of death by use of a common biopsy needle. 相似文献

The first aim of this study was to examine the structure of externalizing and internalizing problem behavior during early
adolescence. Our second aim was to determine the stability of these problems for boys and for girls over time. A total of
650, 13–14-year-olds filled out (an expanded version of) the Youth Self-Report [YSR; Manual for the Youth Self-Report and 1991 Profile. Department of Psychiatry, University of Vermont, Burlington] 2 times with a 1-year interval. By using confirmatory factor
analyses (CFA) to test a series of competing models, a hierarchical model provided the best representation of the structure
of problem behavior at both Time 1 and Time 2: externalizing and internalizing problem behavior represent distinct aspects
but the model also demonstrates the existence of comorbidity at a higher level. This model appeared to be stable over time
for both boys and girls. The relative stability of problem behavior was found to be high for boys and girls. Absolute stability
for both externalizing and internalizing problems appeared to be higher for boys scoring in the lower range of problem behavior.
