Abstract

This paper studies the effects of capital and labor mobility on real wages across Mexican states for the period 1997–2006. Employing dynamic panel data methods, we find: (1) strong positive effects on real wages from foreign direct investment (FDI) and from migration; (2) domestic and foreign migration provide similar wage effects; and (3) alternative partitions indicate that real wages are more sensitive to FDI-related fluctuations across states with relatively lower wages and migration levels. Overall, these results provide support that real wages respond positively to fluctuations in capital flows and labour movements as predicted from the theory.  相似文献

There are many studies on the effects of both economic globalisation and the rise of China. These core issues of the contemporary international agenda entail major economic, military, environmental, social and cultural transformations in most nations. While there is also an abundant literature on how globalisation supported the rise of China, there are scarce publications on how China became one of the primary drivers of globalisation. This article assumes that understanding the power of globalisation over countries is as crucial as assessing the power of certain countries over the process. In this sense, it uses the recently created ‘theory of globalisers’ to analyse how is China transforming contemporary economic globalisation. The conclusion is that China became an ‘economic globaliser’ in the twenty-first century. As the largest exporter, the second largest importer, the third largest provider of foreign direct investments, and a major supplier of high-tech goods, the Asian giant is a vital partner for several economies in different continents. In this context, Beijing’s globalisation strategy aims at both securing the benefits of globalisation and reforming the international economic order, but without a revolutionary stance.  相似文献

The Proof of Concept phase in university technology transfer is considered to be critical for the success of both licensing and the creation of spin-off companies. In the United States, Proof of Concept Centers are emerging as successful structures to address the challenges of this phase. In this paper, we present a framework to assess the role for such a structure in a university ecosystem. The framework is built from previous references that we use to explicitly link the features of Proof of Concept Centers with the challenges of the Proof of Concept phase, and establish their specific contributions to the overall technology commercialization efforts of a university. We illustrate the application of this framework in a case study of the University of Coimbra, in Portugal, and develop a characterization that is representative of the role that a Proof of Concept Center can play in comparable university ecosystems that feature conventional technology commercialization structures, and struggle with the challenges of the Proof of Concept phase. Our study suggests that there is in fact a possible role for a Proof of Concept Center in the regional ecosystem of the University of Coimbra, with a potentially very relevant impact in the technology commercialization process, through networking outside academia and research environments, funding of Proof of Concept activities, and technology entrepreneurship education for the development of entrepreneurial skills for researchers.  相似文献

The Brother-Sister Questionnaire (BSQ; Graham-Bermann and Cutler 1994) is an instrument designed to measure qualities of sibling relationships. Aim: In the present study the main objective was to examine the psychometric properties and validity construct of BSQ - Portuguese version. Data were collected among 197 adolescents. The Cronbach’s alpha of the four domains ranged from .58 to .84. The psychometric characteristics of BSQ Portuguese version were found to be adequate. The results confirm the multi-dimensional model composed of four factors proposed by the authors of this instrument, as well as their suitability to assess quality of Portuguese sibling relationships. The BSQ offers a reliable and valid measure to be used within Portuguese population.  相似文献

Sibling sexual abuse seems to be the most prevalent form of sexual abuse in the family context. This study used the Sexual Coercion Scale of the Revised Conflict Tactics Scales – Sibling Version (Straus et al. 1995) to measure the extent of sibling sexual coercion in a sample of 590 Portuguese university students. Prevalence: 11% of male students and 5% of female students had sexually coerced a sibling in the year when the participant was about 13 years old or in another year. Chronicity: When there was sexual coercion in a sibling relationship, it was perpetrated an average of 22.4 (mean) times by males and 9.1 times by females. Dyadic Concordance Types (DCT’s) revealed that in 26% there was only one perpetrator who was Male-Only, in 19% the perpetrator was Female-Only and more than half (55%) Both coerced. From the perspective of female respondents, in 50% of the cases the perpetrator was a Male-Only, in 31% Female-Only and in 19% Both coerced. Conclusions: Sexual coercion of siblings is probably more frequent than generally realized. Males had higher rates of perpetration, but the percentage of females was substantial. These results suggest a need to expand research to understand the etiology of sibling sexual coercion by females as well as males, understand causes, risk factors and to expand efforts to reduce sexual coercion in sibling relationships.  相似文献

A fast method was designed for the simultaneous determination of amphetamine (A), methamphetamine (MA), PMA, MDA, MDMA, MDEA and MBDB in urine. The drugs were analysed by LC (ESI)-MS/MS, after a simple liquid-liquid extraction in the presence of the deuterated analogues. Reverse phase separation on an Atlantis dC18 Intelligent Speed column was achieved in less than 4 min under gradient conditions, and the total run time was 8 min. The method was fully validated, including linearity (1-1000 ng/mL for A, MDMA, MDEA and MBDB; 2-1000 ng/mL for MDA and PMA; 1-200 ng/mL for MA; r2>0.99 for all compounds), recovery (>80%), within-day and between-day precision and accuracy (CV and MRE<12.7% for intermediate level and ULOQ, and <17.2% for LLOQ), limit of detection (0.2 ng/mL for MDMA, MDEA and MBDB; 0.5 ng/mL for A, MA and PMA; 1 ng/mL for MDA) and quantitation (1 ng/mL for A, MA, MDMA, MDEA and MBDB; 2 ng/mL for MDA and PMA) and relative ion intensities. No matrix effect was observed. The procedure proved to be sensitive, specific and rapid, and was applied to real forensic cases.  相似文献

Establishing a person's identity can be a very difficult process. Dental, fingerprint and DNA comparisons are probably the most common techniques used in this context, allowing fast and secure identification processes. However, since they cannot always be used, sometimes it is necessary to apply different and less known techniques. In this paper, the authors describe two unusual techniques: cheiloscopy and palatoscopy. It is known that due to their special features, both lip grooves and palatal rugae can be used successfully in human identification. This paper reviews the techniques of cheiloscopy and palatoscopy, and describes the different classifications and their advantages and limitations.  相似文献

At the Medical Legal Center in Ribeirão Preto, Brazil (CEMEL/FMRP-USP), unidentified decomposing bodies routinely undergo soft tissue removal (by immersion in water at 80–90 °C for 24 h) prior to an anthropological analysis intended to yield a biological profile of age, sex, ancestry, height, pathology and so on. In the event that this analysis is unsuccessful, samples may be submitted for DNA profiling. The tropical climate and the defleshing process may confound preservation, recovery and analysis of DNA, however. In order to establish an optimal standardized protocol for identification of decomposing human remains from a tropical climatic region, the outcome of anthropological and genetic analyses was compared, along with the utility of bone (mainly femur and sternum) and teeth (mainly molar) specimens for DNA analysis. In a sample (n = 39) of partially skeletonized remains, anthropological analysis was sufficient for identification in eight cases. In further six cases, DNA profiling was successfully attempted. As a consequence of our study, we recommend collection of 1–2 well preserved teeth prior to defleshing and anthropological analysis in these circumstances.  相似文献

This study examined the extent and nature of cyberbullying in 23 Portuguese schools. A sample of 3,525 sixth-, eighth-, and eleventh-grade students completed a self-response questionnaire assessing their perceptions and experiences of cyberbullying. The findings showed that 7.6% of students have been victimized, and 3.9% have bullied others at least once over the last year. The incidences of victimization were higher for females and for the older students. In contrast, more boys reported having bullied others in the eleventh grade. The most frequent medium of cyberbullying was via websites, whilst sending offensive messages was the most widely reported type of behavior. Telling someone about cyberbullying is among the most frequent coping strategies used by cybervictims, who usually chose to tell their friends rather than adults. Implications of these findings for students, schools, and parents are discussed.  相似文献

Forensic strategies commonly are proceeding by analysis of short tandem repeats (STRs); however, new additional strategies have been proposed for forensic science. Thus, this article standardized the high‐resolution melting (HRM) of DNA for forensic analyzes. For HRM, mitochondrial DNA (mtDNA) from eight individuals were extracted from mucosa swabs by DNAzol reagent, samples were amplified by PCR and submitted to HRM analysis to identify differences in hypervariable (HV) regions I and II. To confirm HRM, all PCR products were DNA sequencing. The data suggest that is possible discriminate DNA from different samples by HRM curves. Also, uncommon dual‐dissociation was identified in a single PCR product, increasing HRM analyzes by evaluation of melting peaks. Thus, HRM is accurate and useful to screening small differences in HVI and HVII regions from mtDNA and increase the efficiency of laboratory routines based on forensic genetics.  相似文献
