"The Role of the Senior HR Executive in Japan and the United States: Companies, Countries, and Convergence"

Based on data from an original survey of senior HR executives in Japan and the United States, this paper provides empirical data for evaluating institutional convergence. In both countries, the headquarters HR function has shrunk and that employment decisions have become more decentralized. However, because the pace of change has been more rapid in the U.S., the national gap has widened. Differences persist in other areas, such as the HR executive's role in strategic decisions, perceived power of the HR function, how executives balance shareholder and employee interests, and the consequences of these decisions for corporate governance and organizational outcomes.

Self-Reported Posttraumatic Stress and Borderline Personality Behaviors in Relation to Reports of Traumatic Events, Attachment, Parental Behavior, and Social Support

Borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) are conceptualized as different constructs in the DSM-IV, but research increasingly reveals an association among the symptoms of these disorders. Two relational models were examined: a Shared Risk Factor Model and a Continuum Model. In a sample of 603 college students, principle axis factoring of the Borderline Symptom List and PTSD Checklist showed minimal overlap in symptom presentation, partially supporting a Shared Risk Factor Model. Further support was established as regression analyses showed shared risk factors for reporting a greater number of BPD and PTSD behaviors, including experiencing at least one interpersonal traumatic event, a greater number of incidents of interpersonal trauma, and interpersonal trauma across more age periods (0--4, 5--8, etc.). Mediation analyses suggest only parental behavior mediated the relation between trauma characteristics and PTSD. However, there were multiple mediators of BPD and trauma characteristics, including parental rejection, attachment, and social support by the primary support

Relation of Interpersonal Conflict Behaviors to Emotion Dysregulation and PTSD in Adolescents with a History of Betrayal Trauma

Posttraumatic stress disorder (PTSD) is a disorder that develops in response to exposure to a traumatic stressor. Although this is the most well known diagnosis for individuals who have difficulties after a traumatic event, research documents numerous difficulties and psychopathology that can result from traumatic events, many of which do not fit the DSM-IV criteria of PTSD. Specifically, severe, chronic, interpersonal trauma tends to have a different pattern of effects on individuals than does acute, non-interpersonal trauma. This is particularly true for children (e.g., van der Kolk, Roth, Pelcovitz, Sunday, & Spinazzola, 2005). Because of this, the construct of Developmental Trauma Disorder (DTD) was introduced, although it is not currently recognized in the DSM 5. Emotion regulation skills and interpersonal dysfunction are two core components of this disorder. Trauma perpetrator (i.e., betrayal trauma) has also been found to be an important trauma characteristic when determining the clinical trajectory following traumatic experiences. The current study examined whether adolescents who have experienced betrayal trauma exhibit more negative communication behavior during a stressful interpersonal task, and report more emotion regulation deficits, than adolescents with non-betrayal trauma histories. The study also examined whether emotion regulation mediates the relation between betrayal trauma and negative communication. Finally, analyses were conducted to determine if PTSD or betrayal trauma best predicts negative communication behavior. Adolescents with a history of betrayal trauma reported more emotion regulation difficulties, and exhibited significantly more aggressive, negative non-aggressive, and fewer positive behaviors when engaged in a stressful interpersonal task with their mothers. Although PTSD symptom severity was related to experiencing a betrayal trauma, neither PTSD severity nor PTSD diagnosis predicted interpersonal difficulties as well as betrayal trauma history or emotion regulation difficulties. Finally, emotion regulation difficulties were found to mediate the relation between betrayal trauma and negative communication behavior. These results lend support for adding DTD to the next version of the DSM, illustrating that clinically significant problems related to trauma may not look PTSD-like.

Image Processing for Nondestructive Evaluation

Digital image processing techniques can improve the interpretation and evaluation of radiographic and acoustic image data as well as the time domain waveforms produced by ultrasonic, eddy current, and acoustic emission in two important ways. First, the image or waveform being evaluated can be enhanced to bring out detail not readily apparent to the observer. Second, the properly enhanced image or waveform can be evaluated automatically by computer. The size of defects can be measured and accept/reject decisions made, without relying on the subjective interpretation of an inspector. During the past ten years many new and innovative procedures have been developed for image enhancement and restoration. This presentation describes just one: the spatial filtering technique used to put acoustic and radiographic images in a mode suitable for automatic computer evaluation

Predicting Revision Following In Situ Ulnar Nerve Decompression for Patients With Idiopathic Cubital Tunnel Syndrome.

PURPOSE: To determine the incidence of revision and potential risk factors for needing revision surgery following in situ ulnar nerve decompression for patients with idiopathic cubital tunnel syndrome (CTS). METHODS: We conducted a retrospective chart review of all patients treated at 1 specialty hand center with an open in situ ulnar nerve decompression for idiopathic CTS from January 2006 through December 2010. Revision incidence was determined by identifying patients who underwent additional surgeries for recurrent or persistent ulnar nerve symptoms. Bivariate analysis was performed to determine which variables had a significant influence on the need for revision surgery. RESULTS: Revision surgery was required in 3.2% (7 of 216) of all cases. Age younger than 50 years at the time of index decompression was the lone significant predictor of need for revision surgery. Other patient factors, including gender, diabetes, smoking history, and workers\u27 compensation status were not predictive of the need for revision surgery. Disease-specific variables including nerve conduction velocities, McGowan grading, and predominant symptom type were also not predictive of revision. CONCLUSIONS: For patients with idiopathic CTS, the risk of revision surgery following in situ ulnar nerve decompression is low. However, this risk was increased in patients who were younger than 50 years at the time of the index procedure. The findings of this study suggest that, in the absence of underlying elbow arthritis or prior elbow trauma, in situ ulnar nerve decompression is an effective, minimal-risk option for the initial surgical treatment of CTS.

Sharing the Burden of GHG Reductions

Abstract and PDF report are also available on the MIT Joint Program on the Science and Policy of Global Change website (http://globalchange.mit.edu/).The G8 countries propose a goal of a 50% reduction in global emissions by 2050, in an effort that needs to take account of other agreements specifying that developing countries are to be provided with incentives to action and protected from the impact of measures taken by others. To help inform international negotiations of measures to achieve these goals we develop a technique for endogenously estimating the allowance allocations and associated financial transfers necessary to achieve predetermined distributional outcomes and apply it in the MIT Emissions Prediction and Policy Analysis (EPPA) model. Possible burden sharing agreements are represented by different allowance allocations (and resulting financial flows) in a global cap-and-trade system. Cases studied include agreements that allocate the burden based on simple allocation rules found in current national proposals and alternatives that specify national equity goals for both developing and developed countries. The analysis shows the ambitious nature of this reduction goal: universal participation will be necessary and the welfare costs can be both substantial and wildly different across regions depending on the allocation method chosen. The choice of allocation rule is shown to affect the magnitude of the task and required emissions price because of income effects. If developing countries are fully compensated for the costs of mitigation then the welfare costs to developed countries, if shared equally, are around 2% in 2020, rising to some 10% in 2050, and the implied financial transfers are large—over $400 billion per year in 2020 and rising to around$3 trillion in 2050. For success in dealing with the climate threat any negotiation of long-term goals and paths to achievement need to be grounded in a full understanding of the substantial amounts at stake.Development of the EPPA model used has been supported by the U.S. Department of Energy, U.S. Environmental Protection Agency and U.S. National Science Foundation, and by a consortium of industry and foundation sponsors of the MIT Joint Program on the Science and Policy of Global Change
