Bidirectional labeling and registration scheme for grayscale image segmentation.

In this paper, we introduce a new image segmentation scheme that is based on bidirectional labeling and registration and prove that its segmentation performance is equivalent to that of the conventional watershed segmentation algorithm. The proposed bidirectional labeling and registration scheme, which we refer to as bidirectional labeling and registration scheme (BIDS), involves only linear scans of image pixels. It uses one-dimensional operations rather than the queues that are used in traditional segmentation algorithms, which are two-dimensional problems. BIDS also provides unique labels for individual homogeneous regions. In addition to achieving the same segmentation results, BIDS is four times less computationally complex than the conventional watershed by immersion technique.     

Proteomic tools for the characterization of cell death mechanisms in drug discovery

This review focuses on the use of proteomic tools for the characterization of cell death mechanisms that have contributed to drug discovery efforts. Resistance to cell death plays a major role in the development of many diseases, including numerous types of malignancies. Using a multitude of proteomic approaches, including protein–protein interaction studies, phosphorylation site mapping, ubiquitination site identification, and differential quantitative approaches, various cellular death pathways such as apoptosis and necroptosis have been investigated. These studies have aided in the development of therapeutic strategies or allowed dissection of clinical results to evaluate the success of clinical trials in addition to contributing to our understanding of these biological pathways. Here, we address the new wave of discoveries enabled by advancements in mass spectrometric technology and bioinformatic infrastructure that will hopefully lead to clinically efficacious strategies to overcome resistance to apoptosis and therefore offer improved treatment options for patients.     

Knowledge Domain Spanners in Ideation

Ideation is increasingly receiving attention as a management issue, and we can at present witness the emergence and diffusion of a range of different proactive approaches towards ideation. This development is hardly surprising in the light of the changed nature of innovation activities, including a higher reliance also on external sources for innovation and more focus on non‐technological types of innovation, such as business model innovations. Firms need to handle both a larger number of sources for innovation and more different types of innovations. This article investigates how spanning different knowledge domains influences individuals' ideation performance. A study has been performed using data on all ideas created within an organization during three years. From this data, two broad set of knowledge domains are identified and the influence on ideation of the individuals spanning these domains – the knowledge domain spanners in ideation – are investigated. The empirical results show that knowledge domain spanners in ideation have higher ideation performance than individuals engaged in only one knowledge domain.     

Toward reflective practice: A multicultural competence training model from a community mental health center.

Despite the importance of multicultural competence in clinical practice and training, there is a surprising dearth of innovative training models from fieldwork sites that would be replicable in other practicum settings. The authors illustrate a multicultural competence training model from a community mental health center that highlights the Guidelines on Multicultural Education, Training, Research, Practice, and Organization Change for Psychologists (American Psychological Association, 2003). The model focuses on providing multicultural training through two separate but linked training teams for the dual purposes of internal reflection and reflective practice. The authors conclude with a discussion of the implications of this training model for practice, research, and organizational change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Racial and ethnic identity theory, measurement, and research in counseling psychology: Present status and future directions.

The present article integrates and expands on the special section contributions of K. O. Cokley (2007); J. E. Helms (2007); J. E. Trimble (2007); S. M. Quintana (2007); and J. S. Phinney and A. D. Ong (2007). The authors of the present article begin with a note on politics and ideology in writings on racial identity development and review general progress the field has made on the topics of racial and ethnic identity development. The present challenges in both explicating clear and concise theories of racial and ethnic identity development and operationalizing and measuring these constructs in paper-and-pencil form are identified. The need for interdisciplinary work on theory testing is highlighted, and select examples of best practices in measuring racial and ethnic identity are presented. The article closes with directions for research in racial and ethnic identity development, and with implications for counseling practice, supervision, and systemic change.

Suicidal ideation, antidepressive medication and car crash injury

OBJECTIVE: This study aimed to investigate the association between suicidal ideation, antidepressive medication and the risk of a car crash resulting in serious injury. DESIGN: This was a population-based case-control study. Cases were car drivers who were involved in crashes in which at least one occupant of their car was hospitalised or killed. Controls were selected using a cluster random sample of car drivers on the roads in the same region. Self-reported information on suicidal ideation in the 12 months prior to the crash or roadside survey, current usage of antidepressive medication as well as other crash-related risk factors was obtained from the drivers, or by proxy, using an interviewer-administered questionnaire. SETTING: The study was conducted in the Auckland region of New Zealand in 1998 and 1999. RESULTS: There was a significant association between drivers who had suicidal ideation but without current antidepressive medication and the risk of an injury crash (OR=4.16, 95% CI=2.14-8.10), when compared to drivers without any suicidal ideation. CONCLUSION: The risk of an injury crash was significantly increased for those drivers who reported to have previous or current suicidal ideation but without current antidepressant medication.     

Carbonyls in oxidizing fat. VII. A comparison of methods of isolating monocarbonyl compounds

Comparison of quantitative methods for the isolation of aldehydes from lard oxidized at 23C showed an extreme sensitivity of precursors to isolation conditions. Differences existed in the quantity and class compositions of the monocarbonyl compounds isolated. Acid conditions caused considerable breakdown of alkanal and alk-2-enal precursors. Steam distillation (100C) released alkanals, alk-2-enals, and alk-2,4-dienals. The mild Girard T method apparently produced a small amt of alk-2-enals from precursors, but except in the initial stages isolated the lowest amounts of aldehydes. Complete evaluation of the method for isolation of free aldehydes was not possible because alkanals were released from precursors during the vacuum distillation procedure (50C). The Schwartz (dilute phosphoric acid), Girard T, and vacuum distillation methods isolated similar amounts of alk-2,4-dienals. Curious changes in relationships, possibly indicative of oxidation stages, were observed as autoxidation progressed.
