The Increasing Incidence Of Suicide: Economic Development, Individualism, And Social Integration, Gregory Scott, Joseph Ciarrochi, Frank Deane
The Increasing Incidence Of Suicide: Economic Development, Individualism, And Social Integration, Gregory Scott, Joseph Ciarrochi, Frank Deane
joseph Ciarrochi
Despite significant improvement in physical health, suicide continues to represent a significant burden in the economically advanced countries. Given that the causes of suicide are not fully known, and that suicide cannot be predicted nor prevented at the individual level, national suicide rates might best be reduced by reducing the overall number of people exposed to suicide risk factors. However, economic development promotes individualism and low social integration, both of which increase suicide risk. For example, high female labor force participation and divorce, indicative of low social integration, are associated with higher suicide rates. Similarly, there appear to be social …
Development Of The Levels Of Emotional Awareness Scale For Children (Leas-C), Joseph Ciarrochi, Frank Deane, Jane Bajgar, Richard Lane
Development Of The Levels Of Emotional Awareness Scale For Children (Leas-C), Joseph Ciarrochi, Frank Deane, Jane Bajgar, Richard Lane
joseph Ciarrochi
A performance-based assessment of the structure and complexity of emotional awareness was developed, the Levels of Emotional Awareness Scale for Children (LEAS-C). A pilot study (N=6, ages 9-12, M(age) =10.2 years) was conducted to construct, trial, and select scenarios suitable for the scale. A larger validity study (N=51, ages 10-11, M(age) =10.3 years) examined the relationship between the LEAS-C and two emotion knowledge tasks: emotion expressions and emotion comprehension; two verbal tasks: vocabulary and verbal productivity; and a cognitive developmental measure: the Parental Descriptions Scale (PDS). Gender differences in LEAS-C performance were also examined. The LEAS-C was significantly related to …
Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell
Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell
Howard Casey Cromwell
Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …
Development Of The Sar Tt-Osl Procedure For Dating Middle Pleistocene Dune And Shallow Marine Deposits Along The Southern Cape Coast Of South Africa, Zenobia Jacobs, Richard Roberts, Terry Lachlan, Panagiotis Karkanas, Curtis Marean, David Roberts
Development Of The Sar Tt-Osl Procedure For Dating Middle Pleistocene Dune And Shallow Marine Deposits Along The Southern Cape Coast Of South Africa, Zenobia Jacobs, Richard Roberts, Terry Lachlan, Panagiotis Karkanas, Curtis Marean, David Roberts

Optically stimulated luminescence (OSL) dating is now commonly used to estimate the depositional age of Quaternary landforms along the southern Cape coast of South Africa. Due to the early onset of dose saturation in the quartz-rich sediments from this region, determining the age of deposits much older than the last three glacio-eustatic sea-level high stands has been a challenge. In this study, we explored the feasibility of using the thermally-transferred OSL (TT-OSL) dating method to obtain ages for aeolian and shallow marine deposits at three different localities that hold promise to further illuminate the long and complex Late Quaternary sea-level …

Approaches To Development Of A User-Friendly Community Based Arsenic/Iron Removal Unit In Bangladesh, Khondoker Mahabub Hassan, Farooque Ahmed, Faisal Hai, Saleh Faraj Magram

The present stydy focuses on the strategies to modify the design of a community based Arsenic - Iron Removal Unit (AIRU) based on the field performance of the AIRU and the feedback from the users. The ultimate aim was to offer a user-friendly and sustainable system. Appropriate modifications in the design of the developed unit reduced the propensities of water head-loss and media clogging, thereby yielding sustained flow rate. Introduction of a simple cleaning procerdure (98% flow-recovery with three successive backwashing sequences) successfully reduced the frequency of requirement of labor-intensive replacement of the whole filter media. Raw water with arsenic …
The Development And Management Of A Primary Care Research Network, 1978-87, Donald Iverson, B Calonge, R Miller, L Niebauer, F Reed
The Development And Management Of A Primary Care Research Network, 1978-87, Donald Iverson, B Calonge, R Miller, L Niebauer, F Reed

The Ambulatory Sentinel Practice Network (ASPN) was created to increase the knowledge of primary care. Building on the experiences of other national and regional primary care research networks, ASPN has evolved as a North American network including practices in 25 U.S. states and four Canadian provinces in 1987. This paper summarizes ASPN's growth and development since 1978, the involvement of the ASPN practices, and the mechanisms used in developing and managing studies.

Introduction: Pancreatic cancer (PC) is the sixth leading cause of cancer death in Australia and the fourth in the United States, yet research in PC is lagging behind that in other cancers associated with a high disease burden. In the absence of agreed processes to reliably identify research areas which can deliver significant advances in PC research, the Cancer Council NSW established a strategic partnership with the NSW Pancreatic Cancer Network to define critical research issues and opportunities that could accelerate progress in this field in Australia. Materials and methods: The process consisted of five distinct stages: a literature review …
