War is a highly gendered experience which is both informed by and informs constructions of masculinity and femininity. The dominant depiction of masculine heroes and feminine victims simplifies the complex intersections of militarism, nationalism and gendered roles and identities. Focusing on a case study of the Anglo-Irish War or War of Independence (1919–1921), this paper examines how violence against women, especially sexual violence, was written about and reported in ways which framed representations of Irish and British masculinity and Irish femininity.In addition, by analysing a range of varied sources including newspapers, autobiographical accounts and recorded testimonies, this paper attempts to assess the extent to which violence against women formed a key aspect of military practice in the war. In conclusion, I engage with some of the difficulties faced by researchers today in exploring evidence of gendered violence in specific historical, cultural and militarized contexts.  相似文献

The need to accurately estimate the postmortem interval (PMI) has prompted research into factors affecting fly oviposition (i.e., oviposition and/or larviposition) on a corpse. Research efforts have focused on whether or not diurnally active flies oviposit during nighttime hours. This study reports that nocturnal oviposition (defined as occurring between 2100-0600 h CDST (Central Daylight Savings Time)) did not occur on freshly killed white rats or mice, on beef (fresh or aged up to 48 h), on freshly thawed pigs, nor, usually, on thawed pigs that were aged for up to 48 h. Limited oviposition did occur between 2100 and 2120 h on one bloated pig at a lighted rural site. Necrophilous flies were present and active at lighted and dark sites (urban and rural) before and immediately after sunset, but fly activity on the bait ceased within 50 min postsunset and did not resume until after 0600 h. These observations support other studies reporting that diurnally active flies do not oviposit during the nighttime.  相似文献

  • Corporate 'social responsibility [CSR] is neither a fad nor an optional extra. The interest in it is reflective of a deeper change in the relationship between companies and their stakeholders. Healthy business requires a healthy community, and should be contributing to its creation and maintenance. The public increasingly wants to know about companies that stand behind the brands and products presented to them. And use their power to reward ‘good’ companies and punish the ‘bad’ ones. (Lewis, S. 2001 ).
  • CSR is becoming ever more important in the modern business environment, as is evident by the fact that most leading public companies include a specific statement on their CSR policy within their annual reports. Indeed, changing societal expectations, increasingly intrusive media reporting, and ever more sophisticated and powerful pressure groups have caused all organizations to consider more carefully their wider social responsibilities not only out of altruistic reasons, but because of the need to consider the potential impact of their policies on their wider stakeholder relationships.
  • It is argued in academic and professional writing that CSR orientated organizations benefit from a series of tangible and intangible benefits, when stakeholders are informed of their orientation. Corporations have reacted to these calls and this belief in a business case and are implementing CSR programmes or corporate change to bring about new corporate mindsets, and are in‐turn communicating the results of these programmes. However, in order to be able to effectively communicate it is necessary that organizations clearly understand the concept of CSR, both from a managerial perspective and homogeneous and individual stakeholder perspective.
  • Aiming to help address this lack of understanding, the proposed paper provides a case examination of stakeholder and management perspectives of CSR in the North West of England in a retail setting. The study was conducted in 2003 around a Major UK retail centre using a mix method approach that drew out management cognate viewpoints on CSR and quantitatively tested these findings against stakeholder viewpoints on CSR. The study is served as a pilot for future studies into the area.
  • It found that within the context of the case that the managers and stakeholders (when taken as one homogeneous group) shared a similar view of the concept of CSR. Additionally, the weaknesses of the research pilot brought to the surface methodological improvements that could impact on future researches into the area.

A review of the Southern Africa medical literature shows a paucity of published data regarding lightning fatalities. The South African Highveld has a lightning ground flash density of 6 to 9 flashes/km/year, with a high incidence of thunderstorm days per year (some 40-70). The Highveld has a largely urban population, many of whom have low socioeconomic status and poor education, housing, and other infrastructures and hence (possibly) are at greater exposure risk. Thirty-eight victims of lightning-related death were identified from the records of the 6 large medicolegal mortuaries on the South African Highveld, serving a population of approximately 7 million, for the period 1997 to 2000. Analysis of the records revealed that 95% of all victims were black, 79% were male, and the average age was 36 years. Lightning strikes occurred from September through to April (normal summer rainfall period), and the most strikes took place in the late afternoon (3:00 pm to 6:00 pm). All except 1 case occurred outdoors. In the autopsy reports, mention was made of singeing of hair in 68% of cases, and mention of damage to clothing was made in 26% of cases. Cutaneous thermal injuries were noted in 34 of the 38 cases, with apparent electrothermal injuries of the feet noted in 4 cases. Fifty-two percent of victims sustained some form of associated blunt-force injury (including abrasions, contusions, etc). Specific keraunopathologic injuries were described in only 2 of the cases. Twenty-one cases had some form of internal organ injury. This study serves to illustrate the relatively high incidence of lightning strikes in the region and calls for a more systematic and detailed investigative protocol in lightning-related deaths.  相似文献

A dual processing model of sexual harassment judgments predicted that the behavior of a complainant in a prior case would influence evaluations in an unrelated subsequent case. In the first of two experimental scenarios depicting social-sexual conduct at work, the female complainant's conduct was manipulated to be aggressive, submissive, ambiguous, or neutral. Half of the participants were asked to reflect upon the first scenario after reading it and before answering responsibility questions. The other half simply reviewed the scenario and answered the questions. When the complainant acted aggressively, her behavior in the first scenario caused men who reflected on the fact pattern to find less evidence of harassment. Most interestingly, an aggressive complainant observed in the first scenario caused participants (especially women) to rate lower the likelihood that a neutral complainant in a second independent case was the victim of gender discrimination. Across cases, men found less evidence of harassment than did women.  相似文献

The Y-PLEX 6 and Y-PLEX 5 systems enable analysis for 11 Y-STR loci. We present here the utility of these systems in forensic casework. A total of 188 samples, including 127 evidence samples, were analyzed using either or both of the systems. The evidence sample types included fingernail scrapings, sperm or seminal fluid, epithelial cells, blood and other tissues. The Y-STR typing systems provided useful probative results in difficult cases. A reference database for Caucasian (n = 517), African American (n = 535), and Hispanic (n = 245) population groups within the United States was generated for estimating the haplotype frequency in forensic casework. Among the individuals profiled, 311 Caucasians, 412 African Americans, and 194 Hispanics provided unique profiles in their respective population datasets. This is the first report describing the haplotype database for the set of 11 Y-STR loci recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Linkage analysis reveals that the frequencies from forensically important autosomal loci can be multiplied with the Y-STR haplotype frequency. The results from Y-PLEX systems have been accepted in courts in the United States.  相似文献

A powerful method for validating a scientific result is to confirm specific results utilizing independent methodologies and processing pathways. Thus, we have designed, developed and validated an automated allele concordance analysis system (CompareCalls, patent pending) that performs comparisons between two independent DNA analysis platforms to ensure the highest accuracy for allele calls. Application of this system in a quality assurance role has shown the potential to eliminate greater than 90% of the STR analysis required of a DNA data analyst. While this system is broadly applicable for use with any two independent STR analysis programs, either prior to or following human data review, we are presenting its application to data generated with the ABI Prism Genotyper software system versus data generated with the SurelockID system. With the automated allele concordance analysis system, the GeneScan DNA fragment data generated from an ABI 377 gel image are analyzed in two independent pathways. In one analysis pathway, the GeneScan data are imported into Genotyper software where STR labels are assigned to the fragment data based upon the criteria of the Kazam 20% macro. The "Kazam" macro provided with the Genotyper program works by labeling all peaks in a category (or locus) and then filtering (or removing) the labels from peaks, such as those in stutter positions, that meet predefined criteria. In the second pathway, the GeneScan data are imported into the SurelockID analysis platform where STR labels and error messages are assigned to the fragment data based upon hard-coded allele calling criteria and quality parameters. The resulting STR allele calls for each analysis platform are then compared, utilizing the automated allele concordance analysis system. Any differences in the STR allele calls between the two systems are flagged in a discordance report for further review by a qualified DNA data analyst. The automated allele concordance analysis system guides the DNA data analyst to the discordant data generated by either analysis platform. Additionally, the analyst is also directed to data that are of less than pristine quality which may have an increased potential for errors in interpretation by either analysis platform or by a human DNA data analyst. Implementation of an automated allele concordance analysis system will yield high-quality data for CODIS and free the human DNA data analyst to perform other critical duties within the laboratory.  相似文献
