Pitfalls of Computed Tomography 3D Reconstruction Models in Cranial Nonmetric Analysis*

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes.     

Innovative work behaviour in the public sector: The roles of task characteristics,social support,and proactivity

This study examines the roles of task characteristics, organisational social support, and individual proactivity on innovative work behaviour (IWB) in the public sector. Analysing empirical data from 154 employees from a government agency in Australia, we found that task characteristics, organisational social support, and proactive personality have a positive impact on IWB. Proactive personality is also found to be a moderator in the relationship between task characteristics and IWB. The findings suggest the need to design human resource practices that better identify proactive and innovative job applicants in the recruitment and selection process. Further, we highlight the requirement to organise and design work that recognises the need to develop social support to improve IWB. The implications of the study for further research on IWB are discussed.     

Holding on tight – NPM and the New Zealand performance improvement framework

The New Zealand Government's Performance Improvement Framework (PIF) is aimed at public sector organisational improvement. The PIF exemplifies how the characteristics of new public management (NPM) challenge the evolution of performance systems attempting to go beyond performance management. The paper provides an empirical example of the operation of the PIF, using a theoretical frame derived from the literature. The analysis suggests that the PIF design does not yet mitigate the effects of gaming, synecdoche, and reputation-protecting behaviour. The common graded ratings continue to hold the attention of those to whom the PIF is important, acting as a proxy for the whole performance of the organisation. This is a case study of how, despite promising adaptations, performance improvement efforts remain hampered by NPM limitations.     

Regime type versus patronal politics: a comparison of “ardent democrats” in Kazakhstan and Kyrgyzstan

Kazakhstan is home to the longest serving ruler in post-Soviet Eurasia while Kyrgyzstan is among the region’s most competitive polities. Do these regime differences correspond to divergence in political attitudes, as an extensive body of literature posits? Are Kyrgyzstanis more likely to strongly support democratic ideals? Are Kazakhstanis less likely? Contrary to expectations, data reveal the two populations to be attitudinally indistinguishable when it comes to strong support for practices associated with democracy. Whatever country differences we find are minor or statistically insignificant. We explain this convergence by shifting focus away from the political features that distinguish the two nascent democracy versus consolidated authoritarianism to those that they hold in common. Notwithstanding major constitutional reform in Kyrgyzstan in 2010, politics there, as in Kazakhstan, remains fundamentally patronal, or patronage- based. Mass attitudes, we argue, align in many ways with the countries’ shared patronal politics, rather than with their contrasting regime types.     

ambivalent optimism: women's and gender studies in Australian universities

This article describes the place of Women's and Gender Studies programmes in Australian universities as a way of thinking about the place of feminism in the academy. It begins with a story of one such small programme at a time of stress and locates this story in an account of change in Australian universities over the last 20-plus years. The narrative traces a contradictory domain in which women, feminist scholarship and Women's and Gender Studies are enmeshed. The article draws on feminist literature about Australian universities to argue that while neo-liberal university environments are clearly places where masculinist values prevail, the flows of power around individual Women's and Gender Studies programmes cannot be simply predicted. Women's and Gender Studies programmes are thriving in some universities (on a small scale). As well as institutional imperatives Women's and Gender Studies programmes are engaged by specific intellectual challenges and some of these are sketched with reference to the Australian context. Asserting the need for dedicated research and teaching that focuses on gender, the article concludes that Women's and Gender Studies programmes in Australian universities are energetic places for this to occur. It proposes an ambivalent optimism to describe its assessment of these programmes and their viability as future places of work for feminist scholars.     

E Pluribus Unum: fostering a new era of citizenship by teaching civic engagement and healthy civic discourse

• In a time of profound national challenge and change, it is important to promote a new definition of active citizenship locally, nationally and globally. As the effects of economic, political and social globalization continue to underscore interdependence, the imperative of fostering democratic minds among a citizenry is evermore important. It is essential to conceive a common future that encourages the participation of all American citizens; inviting diversity as an asset and broadly reawakening the call to leverage the rich potentials of pluralism in search of common solutions. However, many schools are retreating from basic civics lessons and are not teaching students how to become active citizens. More importantly, public institutions overall do not appear to be advancing the fundamental awareness and skills required for sifting through political hucksterism, opinion masquerading as news and political spin. It is essential for our schools and public institutions to teach the responsibilities and joy of active citizenship. To meet the challenges of democratic cooperation and social cohesion, leaders and citizens alike should be taught and encouraged to openly question, to critique and even to criticize the status quo. The means for cultivating and institutionalizing such habits on a broad scale involves educational reformation and initiatives in civics and citizenship education to increase opportunities for meaningful public engagement. These are by no means the only answer, but they are a critical component for meeting the challenges of truly inclusive and active representative democracy where out of many, we are one.

One Kazak horseman

We are beginning our trip on the Silk Road near Urumqi, northwest China’s Xinjiang Uygur Autonomous Region. If you picture the map of China, you will see a rooster with the beak. We are touring the rooster’s tail area. Our Uygur guide Kalim, says, "Today we’ll visit a Kazakyurtifwecanfindone." There are no yurts-round-like and portable dwellings-in sight here, just small stucco     

Internships and the State Government Human Resources Crisis

State governments face massive retirements over the next few years. Since internships have been a significant source of bright new blood, we examine what all fifty states are doing with internships. Some exemplary programs were found, but the typical state intern program serves only a few unpaid students, supervisors receive no special training, and no tracking is done to see whether interns stay in state service or what their contributions are. While many states blame stringencies, the budgets involved are comparatively modest and potential benefits significant. We propose an action agenda for state governments and the public administration community.
