Generalized Self-Efficacy of Youth in the New Territories: A Community Survey Conducted by a Hong Kong NGO

Youth are both key participants in debate and a central theme in the discourse on social issues in Hong Kong. Youth are often problematized in the contemporary media and political discussion as lacking in the work ethic, confidence and social skills necessary to be successful. Hong Kong youth are framed as pathologically shy, anti-social, lazy and entitled and these characteristics are used to present an image of Hong Kong youth as having individual characteristics that lead to their challenges in the job market and their characteristics as political rogues. This study approaches the characterization of Hong Kong youth with an intention of gaining a clearer picture of individual characteristics related the problematized image of Hong Kong youth, namely Generalized Self-Efficacy (GSE), a notion connected to a variety of traits. The study is based on community surveys of youth (N=2036) using the GSE instrument conducted in the New Territories communities of Tin Shui Wai and Yuen Long, communities known for high rates of poverty, and public housing. GSE characteristics are analyzed using descriptive statistics, Cronbach’s alpha for internal consistency, factor analysis to verify the dimensional nature of the scale. The relationships between GSE and age and gender were analyzed using multiple linear regression model. Findings indicated that despite a slightly higher, yet statistically significant GSE scores for females, and little impact of age on GSE, Hong Kong youth have normal levels of GSE. This finding offers a counter to the pathologizing of youth’s individual characteristics, and implies the need for a shift in discourse toward more targeted examination of the structural issues that act as barriers to social mobility of today’s young people in Hong Kong

Surgeons' Volume-Outcome Relationship for Lobectomies and Wedge Resections for Cancer Using Video-Assisted Thoracoscopic Techniques

This study examined the effect of surgeons' volume on outcomes in lung surgery: lobectomies and wedge resections. Additionally, the effect of video-assisted thoracoscopic surgery (VATS) on cost, utilization, and adverse events was analyzed. The Premier Hospital Database was the data source for this analysis. Eligible patients were those of any age undergoing lobectomy or wedge resection using VATS for cancer treatment. Volume was represented by the aggregate experience level of the surgeon in a six-month window before each surgery. A positive volume-outcome relationship was found with some notable features. The relationship is stronger for cost and utilization outcomes than for adverse events; for thoracic surgeons as opposed to other surgeons; for VATS lobectomies rather than VATS wedge resections. While there was a reduction in cost and resource utilization with greater experience in VATS, these outcomes were not associated with greater experience in open procedures

Surface processes recorded by rocks and soils on Meridiani Planum, Mars: Microscopic Imager observations during Opportunity's first three extended missions

The Microscopic Imager (MI) on the Mars Exploration Rover Opportunity has returned images of Mars with higher resolution than any previous camera system, allowing detailed petrographic and sedimentological studies of the rocks and soils at the Meridiani Planum landing site. Designed to simulate a geologist's hand lens, the MI is mounted on Opportunity's instrument arm and can resolve objects 0.1 mm across or larger. This paper provides an overview of MI operations, data calibration, and analysis of MI data returned during the first 900 sols (Mars days) of the Opportunity landed mission. Analyses of Opportunity MI data have helped to resolve major questions about the origin of observed textures and features. These studies support eolian sediment transport, rather than impact surge processes, as the dominant depositional mechanism for Burns formation strata. MI stereo observations of a rock outcrop near the rim of Erebus Crater support the previous interpretation of similar sedimentary structures in Eagle Crater as being formed by surficial flow of liquid water. Well-sorted spherules dominate ripple surfaces on the Meridiani plains, and the size of spherules between ripples decreases by about 1 mm from north to south along Opportunity's traverse between Endurance and Erebus craters
