The aim of the study is to present the application of a headspace–gas chromatography–mass spectrometry (HS‐GC‐MS) method for the determination of the carbon monoxide (CO) blood concentration and to compare it with carboxyhemoglobin (HbCO) saturation. In postmortem cases, the HbCO measured by spectrophotometry frequently leads to inaccurate results due to inadequate samples or analyses. The true role of CO intoxication in the death of a person could be misclassified. The estimation of HbCO from HS‐GC‐MS CO measurements provides helpful information by determining the total CO levels (CO linked to hemoglobin (HbCO) and CO dissociated from hemoglobin). The CO concentrations were converted in HbCO saturation levels to define cutoff blood CO values. CO limits were defined as less than 1 μmol/mL for living persons, less than 1.5 μmol/mL for dead persons without CO exposure, and greater than 3 μmol/mL for dead persons with clear CO poisoning.  相似文献

This article examined the differential role of self-rumination and self-reflection on the psychological influence of procedural fairness. Study 1 induced self-rumination and self-reflection relative to an outward-focused control. Self-rumination increased the perceived importance of procedural fairness, whereas self-reflection decreased it. Study 2, assessing individual differences in self-rumination and self-reflection, showed that a standard procedural fairness manipulation (voice vs. no voice) predicted future interaction preferences with the enactment source among those high (but not low) in self-rumination and among those low (but not high) in self-reflection. The findings validate a multiple process approach to understanding the role of the self in procedural fairness.  相似文献

In June 2009, the Commonwealth Attorney General in Australia announced a Family Relationship Centres/ Legal Assistance Partnerships Program, (the “Better Partnerships” program). Its aim was to assist separated or separating families, “by providing access to early and targeted legal information and advice when attending Family Relationship Centres” (McClelland, 2009). After contextualizing this significant shift in policy and practice, the present paper reports on largely positive key results of an evaluation of the program by the Australian Institute of Family Studies. The paper concludes with reflections on future challenges and possibilities regarding ongoing collaboration between Australia's legal and family relationship sectors.  相似文献

The absence of occupational titles for women in historical censuses has stymied numerous scholars. Various authors have explained this phenomenon as carelessness or bias on the part of the census-takers. Women's work was of little interest to the authorities and census officials focused their efforts upon the activities of the head of household. While source triangulation can be a useful tool for uncovering ‘hidden’ employment of women, it is often a complex and time-consuming process. In this article we outline an alternative to deal with the issue of missing occupations of single women in censuses by exploring their living arrangements. We identify four aspects of co-residence that can highlight the roles played within the household by single women without registered employment: their relation to the head of the household, and that individual's occupation, property and marital status. Comparing data from the 1814 population census regarding two social agro-systems and the city of Bruges, we argue that occupational titles of single women were not randomly omitted by the census officials, but reflect the embeddedness of these women in the family economy and household. While we do not refute recent research that stresses single women's economic independence during the long eighteenth century, our findings suggest that for a subset of singles this was not the case. We claim that by studying registered labour only, the historical picture of single women's work is biased or at the very least incomplete.  相似文献

Over the past few decades, China has accumulated over US$3.4 trillion of official foreign exchange reserves as it rises to become a global power. Do China's financial assets increase its ability to pursue its national interests internationally? With the globalisation and rising influence of Chinese state-owned enterprises, state-owned banks and sovereign wealth fund, as well as China's growing clout in several regional groupings, it is clear that China does possess the necessary mechanisms to assert its financial power. This article examines the efficacy and limitations of these mechanisms in Africa and Latin America, in the economic and political domains. In the economic domain, China has consistently used foreign oil contracts and acquisitions to secure direct oil flow from developing nations. An analysis of recent cases shows that while China is able to successfully harness its financial power in its pursuit of oil, it needs to fulfil its promises to the satisfaction of the recipient countries in order to maintain the value of its offers. In the political domain, China has used its financial assets to purchase diplomatic allegiance from various African and Latin American countries in support of its One-China policy. Studying both successful and unsuccessful cases reveals that while China is generally able to use its financial power in third-world countries against Taiwan successfully, its national goals have, in recent years, shifted to the economic realm, even with countries that still recognise the Taipei government.  相似文献

Whereas electoral support for new-rightist parties is often understood as driven by ethnocentric anti-immigrant sentiments, scholars have noted that new-rightist politicians have, surprisingly, stressed culturally progressive arguments in the last decade. Using recent Dutch survey data (N = 1,302) especially collected for this purpose, the article analyses the electoral relevance of three types of cultural progressiveness for voting for the new right and their relation to the well-documented anti-immigrant agenda. The analysis shows that neither moral progressiveness nor aversion to public interference of religious orthodoxy underlies the new-rightist vote. Support for freedom of speech proves relevant, but, in accordance with literature on the new right’s electoral strategy and with theorising on framing, this only leads towards the new right among those who are ethnocentric. These findings are discussed in the light of electoral competition, and questions for further research are formulated.  相似文献

During most of the twentieth century the very existence of judicial errors was considered an awkward subject in the Dutch legal system. This article considers the change of attitude in recent years. In previous years there was a remarkable self-confidence within the criminal justice system (and in most of the scholarly writings) in doing things the ‘right way.’ After a few warnings from (only partly legally trained) scholars, who became interested in the functioning of the system, and moreover, after a few clear and undeniable cases of judicial error, there was a volte-face in the general feeling amongst both the public and the profession. It is the opinion of the authors that this shift in opinion is historically important. This article therefore intends to draw a picture of the current state of affairs in The Netherlands.  相似文献

A number of dyed cellulosic fibres were examined with plane polarized light on their dichroic behavior by microscopy and microspectrophotometry (MSP-PPL). Significant dichroic effects (mostly hypochromic effects and hypsochromic bands shifts) were reported. The effect is related to the chemical structure: some dye structures always possess dichroism (azo, stilbene, thiazole and oxazine), some dyes demonstrate sometimes dichroic effects (anthraquinoid, indigoid) while other structures never demonstrate dichroic effects (sulphur, diphenylmethanes, triarylmethanes, phthalocyanines). In some cases a different dichroic behavior was found for the same dyes applied on cotton and on viscose.  相似文献

As the Covid-19 pandemic began, initial reports suggested that armed groups would seize the opportunity to expand their control over territory and civilians. However, drawing on an original survey of local security officials responsible for monitoring armed group behaviour in Colombia, we find little evidence of significant shifts in the presence or behaviour of political or criminal groups. Contrary to prevailing expectations, we also find that armed group governance is common in areas contested by multiple groups. Our findings shed new light on armed group adaptation to shocks, and challenge the assumption that territorial control is a prerequisite for governance.  相似文献
