Age and sex related measurement of craniofacial soft tissue thickness and nasal profile in the Chinese population

The purpose of this study was to acquire accurate data of craniofacial soft tissue thickness (CFSTT) and nasal profile in Chinese people of Han population. A total of 31 anatomical landmarks and 4 nasal profile parameters were determined using magnetic resonance imaging (MRI) in 425 subjects (233 males and 192 females). In the present study, the mean CFSTT values of male subjects exceeded those of female subjects at most anatomical landmarks except at seven (22.58%) and 6 out of the 7 landmarks were bilateral anatomical landmark points. The age-related and sex × age interactions were found to be statistically significant at all landmarks. Significant differences were found in the nasal profile data of males and females, and 15 out of 20 different groups had significant differences between sexes, and the mean values of nasal length, nasal height, nasal depth and nasal breadth in males were all greater than those in females. Furthermore, both CFSTT and nasal profile showed good correlation with age. The thickest CFSTT of male and female were found at the respective ages of 45-59 and 35-44, and the nasal profile becomes more constant after 24 years of age. CFSTT of the lower part of the face shows greater variation compared to the upper part, so special care needs to be applied when reconstructing the lower portion of the face. Our data on CFSTT and nasal profile for the Chinese Xi'an Han population is important in understanding craniofacial characteristics of the Chinese population and might be potentially helpful in forensic identification.     

Understanding Public Sector Ethics: Beyond Agency Theory in Canada's Sponsorship Scandal

ABSTRACT

Public sector ethics is a topic of ongoing concern in developed democracies. The most popular theoretical approach to this issue is found in principal–agent theory literature. This approach assumes that public sector organizations are populated by principals and agents, each of whom pursue their own self-interest, with agents having a persistent informational advantage. A second approach to ethical conflicts focuses on cognitive processes. According to cognitive theory, all decision makers are vulnerable to “ethical numbing,” particularly in organizational settings that condone the substitution of personal agendas for organizational goals. We argue that Canada's sponsorship scandal has been interpreted almost exclusively from a principal–agent perspective, with subsequent reforms firmly based on introducing new rules to oblige agents to advance the interests of principals. While more faithful adherence to established rules by agents would have avoided a scandal, such adherence is unlikely to be achieved through incentives, monitoring, and penalties as suggested by principal–agent theory. The policy message contained in and implied by the cognitive framework suggests that the focus must be on creating an organizational learning environment that discourages responsible public officials from reframing decision situations in a manner that allows them to become morally disengaged.     

Identity Status,Religious Orientation,and Prejudice

The identity status paradigm has some obvious common ground with the religious orientation paradigm, but surprisingly, there has been very little empirical investigation into the relationship of identity status and religious commitment. The current study investigated hypothesized relationships between identity status and religious orientation and anti-black and anti-homosexual prejudice. One-hundred and seventy-six Christian undergraduate students were administered the appropriate scales. Significant mean differences and correlations were found, mostly in the expected directions for the relationship between identity status and religious orientation. Expected relationships between identity status and prejudice were not found, with the exception of the relationship between foreclosure and both types of prejudice. These results were discussed in light of recent theoretical developments in the identity status paradigm.     

Night Vision Electro-Optics technology transfer: A decade of activity

The US Army’s Night Vision and Electro-Optics Laboratory, Fort Belvoir, Virginia, has for the past decade encouraged the transfer of its unique technology into the non-military community. Our scientists and engineers have developed a wide spectrum of devices that provide the military forces with such benefits as being able to “see” at night without being detected, the ability to accurately determine ranges and to designate targets. Although our objective has been to develop devices to enhance the combat effectiveness of the US Army, many of these night vision and electro-optical devices have a great potential for serving useful functions in the non-military community. Therefore, the technology behind these devices which are not classified may, as the need dictates, be transitioned into the private sector through technology transfer. It is the intent of this paper to provide an introduction to the nature of this technology and to illustrate by high-lighting selected spinoffs, the many uses of night vision and electro-optics which have been adapted by the non-military community.

Retracting suburbia: Smart growth and the future of housing

Abstract

Metropolitan areas throughout the United States increasingly experience sprawl development. States such as Oregon and Maryland have enacted land use legislation that curbs sprawl by promoting denser urban growth. Smart growth, a new method of metropolitan development leading to more compact regions, offers an alternative to sprawl. Given that housing comprises a major share of the built environment, policies that promote denser residential development form a key component of smart growth.

This article provides an analytic review of the ways housing can be used to support successful smart growth policies. It focuses on three areas: the market for higher density housing, land use issues associated with denser housing development, and methods for financing higher density and mixed‐use housing. The literature on the link between smart growth and housing remains underdeveloped. We offer this synthesis as a way to advance the state of knowledge on smart growth's housing dimension.
