In this article, we study how the configuration of a publicly promoted clusters policy??the Global Clusters policy initiated by the Walloon Government in Belgium??influenced the behaviors of R&D practitioners. At first, we explored the background of the Global Cluster policy in an effort to make the program configuration visible. This first step was conducted through the gathering and analysis of data from official documents as well as publications, conference speeches and workshops produced by policy makers, evaluators and their academic collaborators. Then, we observed the transmission of the six resulting features from the policy level to the project level: we studied their appropriation by R&D practitioners in ??Mirage??, an R&D project associated to the mechanical engineering Global Cluster. As a result, we show that the particularities of Walloon Global Clusters make them a powerful instrument to enhance collateral assets while facing potential lock-in. We finally consider the way these Global Clusters should evolve to favor the exploitation of the emerged outcomes while exploring future opportunities. A good balance between exploitation and exploration as well as adequate networking and clustering instruments to support both objectives appear necessary to ensure sustainability and growth of the involved actors. 相似文献

Research examining the impact of self-protective behaviors on outcomes in nonsexual assaults involving intimates has focused solely on one mainstream sample (National Crime Victimization Survey) in which violence is a relatively rare event. Using the Women's Experience of Violence (WEV) project which collects data from a sample of incarcerated women, we explored the phenomenon of self-protective behaviors to assess whether their use impacts the probability and severity of subsequent injury during a domestic violence incident. In addition to utilizing a unique sample, we considered an alternative operationalization of self-protective behaviors that separates physical and verbal responses to include whether the behavior involved an element of force. Results suggest some similarities between a mainstream sample and our marginalized sample. Namely, the frequency in which they utilize countermeasures and the effect of "fighting back" appear to be consistent with previous research. However, the more nuanced categorization of self-protective behaviors demonstrates the importance of considering whether the strategy was forceful when examining women's responses to violence. 相似文献

There is consensus in the partner abuse prevention education literature that a skills-focus is needed. However, appropriate
instruments for evaluating the effectiveness of skills-focused programs do not exist. Against this background, and based on
the dyadic slippery slope model of partner abuse, the Tendency to Resist or End Abusive Dynamics (TREAD) scale was developed.
TREAD is defined as one’s tendency to respond assertively or protectively in situations involving warning-sign (potentially
hurtful or controlling) behaviors by a partner. The scale’s development drew on the input of three Australian samples: mixed-gender
adolescent focus groups, 426 young female respondents to an online survey, and 152 adolescent girls participating in a school-based
program trial. When tested with the 152 adolescent girls, the TREAD scale had acceptable internal consistency and high inter-rater
reliability. Principal components analysis identified three interrelated TREAD subscales (i.e., Conflict-Retaliation TREAD,
Denigration TREAD, and Dominance-Possessiveness TREAD) all of which were negatively associated with frequency of exposure
to warning-sign behaviors. This paper charts the preliminary development of the TREAD scale, presenting evidence supporting
its validity as a change-target for partner abuse prevention education with adolescent girls and, potentially, boys. 相似文献

One crucial element for the evolution of cooperation may be the sensitivity to others?? efforts and pay-offs in comparison with one??s own costs and gains. If an individual responds to a disadvantageous reward distribution, then it would likely increase its relative fitness compared with those who do not (Brosnan & de Waal, Nature 428:140, 2004). Recent experimental research indicates that sensitivity toward unequal reward distribution is not a uniquely human trait; non-human primates react to inequity if they witness a conspecific that obtains a more attractive reward for the same effort. However, primates are not the only species that cooperate and thus would benefit from inequity aversion. Canids also frequently cooperate with group members (e.g., wolves, wild dogs, etc.) or humans (domestic dogs), allowing for the possibility that they also are sensitive to the reward distribution. We report the findings of two studies of dogs?? responses to inequity and the social factors that mediate such responses. In the first study, we investigated whether domestic dogs showed a response to the inequity of rewards received for the same action in pairs of familiar dogs. We found that dogs showed significant behavioral differences when tested without food rewards when in the presence of a rewarded partner compared to the baseline and asocial control situations. This indicated that the presence of a rewarded partner matters (Range, Horn, Virányi, & Huber, Proc Natl Acad Sci USA 106(1):340?C345, 2009). In contrast to primates, dogs did not react to differences in the quality of food or effort. In the second study, we analyzed whether individual (motivational or personality) characteristics determined the response of each subject to unequal reward distributions or whether the subject??s responses depended on the specific relationship they had with its partner. We found that individual motivation and the quality of the relationship influenced the dogs?? performance in test conditions, but that these factors varied across the control and reward inequity conditions. Overall, our results suggest that inequity aversion in dogs is conditional on their and their partner??s rewards. Whether inequity aversion is based on the same mechanisms in both humans and non-human primates is still unclear. 相似文献

The aim of our study was to analyse several serum biochemical markers in order to evaluate the discriminant capacity of trace elements individually and jointly in drowning (seawater drowning and freshwater drowning) and their correlation with age, sex, postmortem interval, time in water and concentrations of the trace elements in the drowning medium. Sixty-seven cases of drowning (53 seawater drownings (SWD); 14 freshwater drownings (FWD) and 73 control cases (other asphyxias, n=44, and other causes of death, n=29) were selected according to the scene, cause and circumstances of death, together with autopsy findings. Serum strontium (Sr), magnesium (Mg), sodium (Na), chloride (Cl), calcium (Ca), iron (Fe), urea, creatinine (Cr) and cardiac Troponine T (cTn-T) were measured in the left ventricle (Lv), right ventricle (Rv) and peripheral blood. Lv-Rv differences for each marker and Sr, Mg, Na, Cl, Ca and Fe concentrations in the drowning medium were determinated. Mean concentrations of Sr, Cl and Mg in both ventricles and peripheral serum and Lv-Rv differences and Ca Lv and Na Rv were significantly higher in cases of drowning than for other causes of death. In SWD, Sr, Mg, Ca, Na and Cl were significantly higher in Lv than in Rv as a result of aspirating water. In contrast, haemodilution is evident from the significantly higher levels of Fe and urea in Rv than in Lv in cases of SWD, and from the higher Mg and Cr levels in Rv in FWD. In the case of SWD, serum levels of Sr are confirmed as the best parameter for diagnosis, although other trace elements may also be useful, such as the serum concentrations of Mg and Cl. In the case of FWD, the joint determination of Sr and other biochemical markers, especially Fe, may increase correct diagnosis. 相似文献

In recent years, both scientific and judicial sources have highlighted the need for more knowledge about minutiae variability, in order to improve their statistical application to fingerprint identification. In line with this trend toward improving our knowledge of this subject, the aim of the present study was to calculate the frequency with which 20 types of minutiae appeared in 2780 fingerprint impressions obtained from 278 individuals from two Argentinian population samples (100 individuals from Ramal and 178 from Puna-Quebrada). The different types of minutiae were located, identified, and quantified visually in two areas on the fingerprint, the inside and outside of a circle, the radius of which cut fifteen ridges perpendicularly, starting from the center cut of the axes defining the sectors. The non-equiprobability found in both population samples for the different minutiae types studied demonstrated that the evidential weight provided by these characteristics is not the same when applied in identification processes, whether used quantitatively (numerical standard) or qualitatively (holistic method). The results obtained for both populations were compared statistically with those published previously for a Spanish population sample, which had been collected using the same methodology. This comparison has enabled us to demonstrate, for the first time, the existence of significant differences between populations in minutiae frequencies, independently from the main pattern type. 相似文献
