Determination of stature from skeletal and skull measurements by CT scan evaluation

The aim of this article is to find a correlation between height and femur/skull measurements through Computed Tomography (CT) scans and derive regression equations for total skeletal height estimation in the Caucasian population. We selected 200 Caucasian patients from March 2010 to July 2011 who had to perform a CT scan for cancer restaging. The mean age is 64.5 years. Both sexes are represented by the same number of persons. Patients have executed a total body CT scan with contrast; once scan accomplished, we measured height through a digital scales. We analyzed CT scans of each patient, obtaining multiplanar reconstruction in sagittal and coronal planes with 1mm of thickness, and we measured 10 diameters of skull and femur. Then we performed a single and a multiple regression analysis considering the three diameters that better correlated with height. The skeletal diameters with the highest correlation coefficients with stature were femur lengths, length of cranial base (Ba-N), and distance from the posterior extremity of the cranial base to the inferior point of the nasal bone (Ba-NB). Although both femur and skull are skeletal segments used for stature estimation, in our sample femur gave stronger correlation with height than skull. h=35.7+1.48·BaN+2.32·BaNB+2.53·FEM and h=3.06·FEM+72.6 are the formulae that provided the most accurate stature assessment using multiple and single regression analysis respectively.     

Can we handle the truth? Legal fictions in the determination of death

Advances in life-saving technologies in the past few decades have challenged our traditional understandings of death. People can be maintained on life-support even after permanently losing the ability to breathe spontaneously and remaining unconscious and unable to interact meaningfully with others. In part because this group of people could help fulfill the growing need for organ donation, there has been a great deal of pressure on the way we determine death. The determination of death has been modified from the old way of understanding death as occurring when a person stops breathing, her heart stops beating, and she is cold to the touch. Today, physicians determine death by relying on a diagnosis of total brain failure or by waiting a short while after circulation stops. Evidence has emerged that the conceptual bases for these approaches to determining death are fundamentally flawed and depart substantially from our biological and common-sense understandings of death. We argue that the current approach to determining death consists of two different types of unacknowledged legal fictions. These legal fictions were developed for practices that are largely ethically legitimate but need to be reconciled with the law. However, the considerable debate over the determination of death in the medical and scientific literature has not informed the public of the fact that our current determinations of death do not adequately establish that a person has died. It seems unlikely that this information can remain hidden for long. Given the instability of the status quo and the difficulty of making the substantial legal changes required by complete transparency, we argue for a second-best policy solution of acknowledging the legal fictions involved in determining death. This move in the direction of greater transparency may someday result in allowing us to face squarely these issues and effect the legal changes necessary to permit ethically appropriate vital organ transplantation. Finally, this paper also provides the beginnings of a taxonomy of legal fictions, concluding that a more systematic theoretical treatment of legal fictions is warranted to understand their advantages and disadvantages across a variety of legal domains.     

Staff experiences of working in a Sexual Assault Referral Centre: the impacts and emotional tolls of working with traumatised people

This study considers the impacts on staff of supporting people who have reported sexual violence and attend a Sexual Assault Referral Centre (SARC). This paper focuses on the staff’s perspectives of the stresses and emotional tolls they experience including the coping mechanisms they utilise. Semi-structured interviews were conducted with 12 staff, and a focus group was held with a further four staff of a SARC. The data were examined using thematic analysis. Findings indicated that staff experienced positive emotions connected to the meaningfulness of the work and team spirit as well as a range of unpleasant emotions. Staff also reported emotional numbing, in connection to the specificity, volume and sometimes unpredictable nature of the work. Coping mechanisms used by staff focused on the supportive connection to family, nature, and other team members; the value of clinical supervision; and the avoidance of topics related to work.     

Evaluating Measures of Campaign Advertising Exposure on Political Learning

Scholars employ various methods to measure exposure to televised political advertising but often arrive at conflicting conclusions about its impact on the thoughts and actions of citizens. We attempt to clarify one of these debates while validating a parsimonious measure of political advertising exposure. To do so, we assess the predictive power of six different measurement approaches—from the simple to the complex—on learning about political candidates. Two datasets are used in this inquiry: (1) geo-coded political advertising time-buy data, and (2) a national panel study concerning patterns of media consumption and levels of political knowledge. We conclude that many traditional methods of assessing exposure are flawed. Fortunately, there is a relatively simple measure that predicts knowledge about information featured in ads. This measure involves combining a tally of the volume of advertisements aired in a market with a small number of survey questions about the television viewing habits of geo-coded respondents.     

A scientific approach to measure public political participation in Pakistan

Public political participation is an exhaustive subject in the democratic system that is contributing as a tilled land since the birth of democracy. It has a wide range of frequency, but voting is one of the easiest among all forms of public participation. Despite the easiness of voting, Pakistan ranks 164th in terms of voter turnout among 169 countries of the world. The voter turnout of the second largest Muslim democracy and the fifth largest among all the democratic states was recorded as 45.3% in the 2013 general election, which was less than India’s (59.4%) and even Bangladesh’s (58.2%). More than half of the population in Pakistan does not think it is its duty to cast its vote. The present study is an effort to investigate public political participation through six independent variables: democratic political party, party mobilization, security, accessibility, leadership image and moderating factor citizen distrust, and a useful sample size of 1884 was collected across the country. SPSS version 24.0 was used to measure the data. The results show significant and positive relations among the dependent and independent variables, while citizen distrust negatively moderates the dependent and independent variables of the study.     

The Rise of Resilience in Education in Emergencies

ABSTRACT

This article explores how resilience as a concept is being increasingly mobilised within the Education in Emergencies (EiE) community. Using content and a close textual analysis, it identifies the concept's growth in prominence within key EiE documents arguing it has been employed to serve a range of different purposes. It contends, however, that dominant conceptualisations of resilience within the EiE community are reflective of a number of shifts around the problem, subjects and purposes of education provision in such conflict-affected contexts. This serves to limit the transformative potential of resilience, particularly in regards to contributing to positive peace.
