耻骨推断年龄方程改进   总被引:2,自引:0,他引:2  
为了进一步提高耻骨推断年龄方程推广使用价值,在原方程454副样本基础上又增加146副,共600副(男、女各300副)。观测项目(形态特征)由男女各9个减为各8个。有效赋分标准,男性增加5个;女性增加4个。每项中0改为1。使用数量化理论1和逐步回归数学模型,取得8个方程、6个推断年龄表。应用时可根据不同性别、不同年龄组,选用不同推断年龄表,使用不同标准差。比原方程,提高了实际应用价值。  相似文献

The question of whether a citizen is obliged to obey the law has occupied scholarly thinking since the days of Socrates. Thus, rarely has the question been examined empirically. Based on a survey of 1866 adults, citizens of the state of Israel, this study attempts to construct causal models linking socioeconomic status to subjective measures of injustice, and further to indicators of illegalism and disobedience among Jews and Arabs. LISREL analysis has been found a useful tool to construct the empirical models that measure how members of the two ethnic communities relate to the boundaries of the prima facie obligation to obey the law. Findings show that those who have no trust in one part of the legal system, will also have no trust in the rest of the system which, in turn, serves to legitimize taking the law into one's own hand.  相似文献

Abstract

This paper presents the results of a survey evaluating the views of 1322 residents of York, UK around their perceptions and attitudes towards crime, their local area, and the police with the aim of understanding the main factors affecting public confidence within the city. The study uses Structural Equation Modelling to develop several models which are evaluated to examine whether differences in public confidence in the police exist across disparate local communities with varying degrees of neighbourhood perceptions. The results indicate that even in a relatively small city such as York, the factors which most affect an individual’s views of the police can vary wildly depending on an individual’s perceptions regarding their local area. The results suggest that policing strategies aimed at improving public confidence must be altered depending on the views residents hold regarding their local communities.  相似文献

中国黑龙江地区汉族未成年人的牙钙化程度及年龄推断   总被引:4,自引:2,他引:2  
目的探讨未成年人牙齿钙化程度与其年龄的关系,建立根据牙齿钙化程度推断未成年人年龄的方法。方法拍摄黑龙江地区1510名未成年人(男737名,女773名,年龄6~15周岁)牙齿曲面断层影像片,利用计算机观察全口曲面断层影像片中下颌恒牙牙位处钙化程度的影像特征,并建立牙齿钙化分级评分标准,然后根据此标准对下颌牙齿进行分级评分;将其结果输入SPSS13.0软件统计,按α=0.05对牙齿钙化分值分性别分年龄段组进行非参数检验和与年龄的相关性分析,最终建立根据牙齿钙化程度推断年龄的回归方程。结果同名牙左右侧无差异(P〉0.05),而性别间有差异(P〈0.05);男女性下颌牙齿的钙化程度均与年龄高度相关(r〉0.7);所建方程模型合理可靠,盲测结果显示推断年龄与实际年龄间无统计学差异,误差绝对值的平均值男性为(0.367±0.257)岁,女性为(0.367±0.245)岁。结论本研究中未成年人牙齿钙化程度随年龄的增长而呈现增高趋势,直至完全钙化;根据牙齿钙化程度建立的回归方程可用于未成年人活体以及无名尸体的年龄推断。  相似文献

Existing literature on the City of London has tended to focus on its ‘structural power’, while neglecting political and narrative agency. This paper acts as a corrective by presenting evidence to show that since the financial crash of 2008 the political terrain the City operates on has become more contested, crowded and noisier. The contribution develops a middle course between a positive assessment of the role of civil society in relation to global finance, and a more pessimistic reading. We demonstrate how macro-narratives and public story-telling both construct and contest City and financial sector power. In a new pattern since the financial crash, NGOs have moved from campaigns of limited duration and narrow focus, to a more sustained presence on macro-structural issues. Adopting a supply–demand framework for assessing governance and regulatory change, we look at the emergence of TheCityUK as a new advocacy arm and the strategies of three of the more prominent and focused NGOs that have mobilized in the aftermath of the crash: the Tax Justice Network’s (TJN) use of the ‘finance curse’; Positive Money on private endogenous money creation; and Finance Watch counterweight strategies at the level of the European Union. We suggest these mobilizations highlight the need for a more concerted and orchestrated construction of a global institutional civil society infrastructure in finance (a global financial public sphere) to achieve greater access, resources, scrutiny and oversight for a range of specialist expert NGOs.  相似文献

Structural changes are commonly undertaken to achieve gains, such as enhanced efficiency and performance. In this paper, we explore the cultural issues associated with a structural change in the Australian Public Service. We argue that cultural differences across merged functions were disruptive and challenging to overcome. We posit, however, that these challenges were exacerbated by the lack of systemic effort to integrate cultures, thus impeding synergy realization. Our findings are consistent with the private sector literature that warns mergers and acquisitions undertaken with too much haste and without adequate planning can lead to cultural issues when not managed appropriately.  相似文献

Stature estimation methods for Danish adult population have generally relied on Trotter and Gleser’s and Boldsen’s regression equations that are based on the skeletal remains of recent war dead American Whites, Terry Skeletal Collection, and Danish archaeological medieval skeletal materials, respectively. These equations are probably not suitable for stature estimation in contemporary Danish forensic cases. Furthermore, because postmortem computed tomography (PMCT) is now routinely performed at Danish forensic departments, equations based on PMCT, rather than measurements of defleshed bones, are needed. The aim of this study was to develop new equations for adult stature estimation based on PMCT femoral measurement. Maximum femoral length was measured on the PMCT images of 78 individuals (41 males and 37 females) aged 23–45 years. The measurement accuracy was tested on dry bones, and all the measurements were included in the inter- and intra-observer analyses. Both analyses results demonstrated the reliability of the method and data. Comparison between the living stature of the individuals and the estimates based on the equations by Trotter and Gleser and Boldsen demonstrated the unreliability of the previous equations to some extent. New regression equations were then developed and validated on a different sample of 18 Danish forensic cases. Comparisons of all the equations indicated that both the sets of previous equations underestimated the stature in the new validation dataset. The new equations developed in this study provide a reliable alternative for stature estimation in modern Danish forensic cases.  相似文献

Improvements in information and communication technologies have reshaped production and consumption relations during the post-modern era. Societies have tried to adapt themselves to the requirements of new knowledge-based economy. It has also become vital for the organizations to meet the needs of knowledge society. Whether they are public or private, organizations play key roles in the transformation processes of the societies and economies. It is important for the organizations not only to use the latest information technologies, but also create social structures, which can ease information flow throughout the organization. Social network studies that are quite different from traditional approaches in sociology can be very useful tools to understand arid manipulate organizational networks. The results of several research activities have shown that actors use their social connections to reach information, resources and possible opportunities (Garguilo & Benassi, 2000). It is not enough to use advanced information technologies in an organization to build an effective knowledge distribution system regarding the social network perspective, it is required to understand the patterns of social interactions between actors and to find a fit between technical structure and social structure for effective knowledge-based organizational design. Structural holes theory (Butt, 1992) emphasized the importance of brokerage roles of the actors in a social network. Structural holes are unconnected actors (individuals, groups or organizations) in a social network (Burt, 1992). If there are numerous structural holes in an organization, there will also be quite a number of brokerage opportunities for some actors in the organizational networks. Brokers are the bridges and gatekeepers who are controlling information flow in the organizations. It is vitally important to explore brokerage patterns in an organizational network for an effective knowledge based design. This study is a conceptual framework aiming at bringing an explanation to socially created information flow structures in the organizations by using structural holes theory.  相似文献
