We investigate the role of search strategy in shaping firms’ innovation performance. Firms use a wide range of external actors and sources to help them achieve and sustain innovation. In particular, the extension (breadth) and the relevance (depth) of such sources determine firms’ ability to extract and exploit knowledge and new ideas and, thus, to be innovative. Using a sample of firms in a regional context active in R&D, we built separate measures of breadth and depth for local (on a regional scale) and global (outside the regional context) search. This allows us to investigate whether localized or global knowledge spillovers are in place. We find that a wider set of partners increases coordination costs, while greater depth in search strategies contributes to innovation. We find that a more diversified search strategy at the local level (greater breadth of search) results in significant payoffs in terms of innovation, while diversifying the partnership with Italian partners has a smaller, although still positive, effect. In contrast, the benefits of depth of innovation are greatest at the global level. In addition, a broader set of information sources for R&D projects has a significant positive effect on innovation. Finally, firms that resort to R&D subsidies are less innovative. 相似文献

Family and social environment may play a part in children’s post-violence adjustment. The goal of this paper is to examine which factors are related to internalizing symptoms in mothers and their children exposed to intimate partner violence. Participants were 208 mothers exposed to domestic violence. Mothers responded using the Conflict Tactics Scale, Beck Depression Inventory, and other standardized scales. They also reported on their children’s internalizing symptoms using the Child Behavior Checklist (CBCL). For the whole group, children’s CBCL scores were related to higher maternal depression and lower maternal self-esteem. Factors determining internalizing in children varied based upon the child’s race. This study illustrates the importance of factors, such as maternal depression, maternal self-esteem, violence exposure, and social support, in determining whether a child exposed to domestic violence develops internalizing symptoms, and that ecological factors may have different effects on children based on race. 相似文献

Counterfeit parts in the U.S. Department of Defense (DOD) supply chain threaten national security by compromising critical military operations and placing the lives of military service members at risk. With the goal of illustrating the nature of the risk as it relates to types of counterfeit parts, how they entered the supply chain, and were identified and processed through the criminal justice system, we assemble and analyze open-source information on criminal schemes involving counterfeits in the DOD supply chain. We utilize the Product Counterfeiting Database (PCD) to capture every indicted scheme linked to the DOD and describe characteristics of the schemes, offenders, and victims. These data provide empirical insights into the counterfeiting of parts and equipment in the DOD supply chain. We conclude with an overview of key issues to consider when weighing opportunities for product counterfeiting as well as implications for policy and practice. 相似文献

Survivors of intimate partner violence have myriad reasons why they turn to domestic violence shelter programs. While all are seeking immediate safety and feel a pressing need to leave their homes to obtain it, safety is rarely the only issue survivors are grappling with upon shelter entry. Other concerns are particular to each person’s history and circumstances, and include but are not limited to employment, counseling, social support, health care, addiction recovery services, immigration help, housing, and services for their children. The current study involved secondary analysis of survey data completed at two points in time by 565 shelter residents. The original research involved 215 domestic violence programs across eight states in the U.S., and surveys were completed by shelter residents shortly after they arrived in shelter and again as they were close to exiting. Results confirmed that survivors had numerous needs in addition to safety when entering shelter. Residents’ overall rating of how helpful their stay at shelter had been for them was predicted by how much help they had received across their presenting needs, as well as how they were treated by staff. The amount of help received, as well as treatment by staff, also related to survivors’ hopefulness at shelter exit, as well as the extent to which they felt better able to do things on their own. The study findings provide further evidence that domestic violence shelter staff assist residents with a variety of complex needs in addition to safety, and that this assistance is related to positive outcomes for survivors. 相似文献

Differences between traditional Muslim marriage practice and the statutory formalities required for entry into a legally recognised marriage in England and Wales have resulted in serious question-marks hanging over the legal status of a seemingly significant proportion of Muslim marriages. This article places the spotlight on the vulnerability of spouses who remain unaware of the lack of legal status which may attach to their marriage or who may have been misled by their spouse as to the latter’s intention to obtain legal recognition for the marriage. The article first considers the statutory formalities required under English law for entry into a legally recognised marriage before drawing on the most up-to-date empirical research to highlight the apparently widespread non-compliance with the formalities within the Muslim community. The article then reflects on the various practical implications which may arise for parties to an unrecognised Muslim marriage before considering how the situation may be ameliorated. 相似文献

We use National Incident-Based Reporting System (NIBRS) data and an AutoRegressive Integrative Moving Average (ARIMA) study design to investigate the effect of moon illumination on reported crime occurring outdoors between the hours of 10 pm to 2 am in 13 U.S. states and the District of Columbia. Prior research analyzed a confounded dependent variable that amalgamated indoor and outdoor crimes. This situation is problematic in that there is little reason to speculate a relationship between moon illumination and indoor crime because artificial illumination is used within dwellings. Findings show that while moon illumination has little influence on total crime and indoor crime, the intensity of moonlight does have a substantive positive effect on outdoor criminal activity. As moon illumination intensifies, outdoor crime increases markedly. Plausible explanations for this relationship are discussed. 相似文献

Sudden cardiac death due to giant cell inflammatory processes 总被引:1,自引:0,他引:1
Granulomatous inflammation of the myocardium may occur in a number of systemic disease processes including those with infectious etiologies such as fungal, mycobacterial and parasitic infections, as well as hypersensitivity reactions, and rarely autoimmune disorders. In many of these disorders, giant cells are components of the inflammatory infiltrate. Systemic granulomatous processes of unknown pathogenesis, most notably sarcoidosis, may also be associated with involvement of the myocardium. Occasionally, these disorders are associated with sudden death due to pathologic involvement of the heart. In contrast, giant cell myocarditis, also known as idiopathic myocarditis, a rare, frequently fulminant and fatal disorder of unknown etiology, is isolated to the heart and lacks systemic involvement. This disorder is most commonly diagnosed at autopsy. We present two cases in which sudden death resulted from a giant cell inflammatory process affecting the myocardium. Both individuals lacked antemortem diagnoses and collapsed at their respective places of employment. These cases compare and contrast the clinical and pathologic issues involved in the differential diagnoses of the subgroup of sudden cardiac deaths resulting from giant cell inflammatory processes that affect the myocardium, as well as the value of histologic examination and immunohistochemical studies. 相似文献

The article describes the method defining 5 alleles of ABO blood group typing system by molecular hybridization in hydrogel oligonucleotide microchip. The testing points were SNP variants in positions 261 and 297of exon 6 and in positions 646 and 657 of exon 7. Therefore, 5 ABO blood groups can be easily revealed: A, B, 0(1), 0(1v), 0(2). The method was tested on 10 DNA samples isolated from blood and saliva of unrelated individuals. The results were confirmed by sequencing of the identified allelic fragments. Estimation sensitivity was 25 pg of total DNA input. This technique is cost-effective and easy for use and, therefore, promising for forensic-medical personal identification. 相似文献
