Posttraumatic stress disorder (PTSD) symptom profiles among people who have experienced abuse: Findings from the NESARC-III study.

Greater recognition of diversity in psychological responses to traumatic events has led to increased exploration of posttrauma symptom typologies and risk factors for more "complex" presentations. OBJECTIVES: We sought to identify unique PTSD symptom profiles associated with the experience of physical and sexual abuse and to determine whether exposure in childhood, type of abuse, frequency of abuse and familial support were associated with profiles indicating increased symptom complexity. METHOD: We analyzed data from 6,769 American adults (M = 43.93 years, SD = 15.35, 70.9% female) from the National Epidemiologic Survey on Alcohol and Related Conditions-III who reported histories of physical or sexual abuse. Latent Class Analysis was used to identify distinct profiles of the twenty PTSD symptoms outlined in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). Abuse in childhood, type of abuse, frequency of childhood abuse, emotional support in childhood and a range of demographic variables were compared across classes. RESULTS: Five classes were educed: High All (19.6%), Threat (14.4%), Dysphoric (13.7%), Moderate Threat (29.4%) and Low Symptom (22.9%). Contrary to our hypotheses, trauma exposure in childhood did not predict class membership while type of abuse did. The High All and Dysphoric classes had greater frequency of childhood abuse, lower support in childhood, and a history of sexual abuse when compared to their less complex, predominantly fear-based counterparts (Threat and Moderate Threat classes, respectively). CONCLUSIONS: These constellations of DSM-5 PTSD symptoms may be a proxy for increased "complexity" and may indicate a need for alternative or additional therapeutic interventions.

Backbone of complex networks of corporations: The flow of control

We present a methodology to extract the backbone of complex networks based on the weight and direction of links, as well as on nontopological properties of nodes. We show how the methodology can be applied in general to networks in which mass or energy is flowing along the links. In particular, the procedure enables us to address important questions in economics, namely, how control and wealth are structured and concentrated across national markets. We report on the first cross-country investigation of ownership networks, focusing on the stock markets of 48 countries around the world. On the one hand, our analysis confirms results expected on the basis of the literature on corporate control, namely, that in Anglo-Saxon countries control tends to be dispersed among numerous shareholders. On the other hand, it also reveals that in the same countries, control is found to be highly concentrated at the global level, namely, lying in the hands of very few important shareholders. Interestingly, the exact opposite is observed for European countries. These results have previously not been reported as they are not observable without the kind of network analysis developed here.Comment: 24 pages, 12 figures, 2nd version (text made more concise and readable, results unchanged

The Relationship between Emotion Dysregulation and Postnatal Attachment in Women Admitted to a Mother Baby Unit

Mothers with insecure attachment styles may have increased difficulty establishing secure attachment with their infant and may experience emotion regulation difficulties in the postpartum period. This study aimed to examine the mediating effect of emotion dysregulation (ED) on the relation-ship between maternal insecure attachment style and self-reported attachment to infant in women admitted to a mother-baby unit

How far that little candle throws his beams! An interview with Mats Isaksson

This article adopts a policy-maker perspective on corporate governance, while exploring the role of academia in influencing corporate governance principles, the reasons for the boilerplate approach to governance rules typically adopted by most companies, and the reasons for a possible disconnect between research and corporate governance policies. The article ends with some key lessons about corporate governance and the future research agenda

The Inter-Rater Consistency of Clinician Ratings of Posttraumatic Stress Disorder (PTSD) Therapy Content.

Effective communication between clinicians is essential for the success of mental health interventions in multidisciplinary contexts. This relies on a shared understanding of concepts, diagnoses and treatments. A major assumption of clinicians when discussing psychological treatments with each other is that both parties have a shared understanding of the theory, rationale and application of the respective technique. We aimed to determine to what extent there is inter-rater agreement between clinicians in describing the content of group therapy sessions. Pairs of clinicians, drawn from a large multidisciplinary team (13), were asked to provide ratings of the therapeutic content and emphasis of N = 154 group therapy sessions conducted during an intensive residential treatment program for post-traumatic stress disorder (PTSD). In most therapeutic content domains there was a moderate level of agreement between clinicians regarding session content (Cohen's Kappa 0.4 to 0.6), suggesting that clinicians have a broad shared understanding of therapeutic content, but that there are also frequent discordant understandings. The implications of these findings on multidisciplinary team communication, patient care and clinical handovers are discussed and directions for further research are outlined

Testing the spectrum hypothesis of problematic online behaviors: A network analysis approach.

The validity of the constructs of problematic Internet or smartphone use and Internet or smartphone addiction has been extensively debated. The spectrum hypothesis posits that problematic online behaviors (POBs) may be conceptualized within a spectrum of related yet distinct entities. To date, the hypothesis has received preliminary support, and further robust empirical studies are still needed. The present study tested the spectrum hypothesis of POBs in an Australian community sample (n = 1,617) using a network analysis approach. Psychometrically validated self-report instruments were used to assess six types of POBs: problematic online gaming, cyberchondria, problematic cybersex, problematic online shopping, problematic use of social networking sites, and problematic online gambling. A tetrachoric correlation matrix was computed to explore relationships between online activities and a network analysis was used to analyze relationships between POBs. Correlations between online activities were positive and significant, but of small magnitude (0.051 ≤ r ≤ 0.236). The community detection analysis identified six distinct communities, corresponding to each POB, with strong relationships between items within each POB and weaker relationships between POBs. These findings provide further empirical support for the spectrum hypothesis, suggesting that POBs occur as distinct entities and with little overlap

Investigation of the Phenomenon of Propagated Sensation along the Channels in the Upper Limb Following Administration of Acupuncture and Mock Laser

© 2017 Background Similar to De Qi psychophysical responses, propagated sensation along the channels (PSC) is considered an important phenomenon in traditional Chinese acupuncture. In acupuncture clinical trials, different acupuncture manipulation techniques are used to enhance the propagation of sensation along the channels to facilitate an optimum therapeutic result. Aim To examine and compare the PSC reported by participants in a clinical trial following the administration of acupuncture and inactive mock laser. Methods The study was embedded in a two-arm parallel design multicenter, randomized clinical trial, the Tennis Elbow Acupuncture—International Study—China, Hong Kong, Australia, Italy (TEA IS CHAI). Needle sensations were measured using a validated instrument, the Massachusetts General Hospital Acupuncture Sensation Spreading Scale. Ninety-six participants with lateral elbow pain were randomly allocated into two groups in a 1:1 ratio; the acupuncture treatment group (n = 47) and the mock laser control group (n = 49). Participants in both groups received the intervention at two acupoints, LI10 and LI11, consisting of 2 minutes of either standardized needle manipulation or mock laser at each acupoint with a rest period between each intervention period. Data were collected immediately following the interventions at the first and the ninth session within the clinical trial. Results Although participants in both groups perceived PSC radiating to similar sites along the upper limb, the frequency of the reported radiation sites among the two intervention groups for both radiation up the limb (p < 0.05) and radiation down the limb (p < 0.001) were statistically significantly different. Among the radiating sensation sites recorded within the two study groups, the sensations were reported as radiating a greater distance down the forearm to the wrist compared to up the arm. Evaluation of PSC across the four study sites revealed a statistically significant difference in frequency of the reported radiation down the limb sites in each study group and radiation up the limb sites only in control group only (p < 0.001). Conclusion The findings of the study demonstrated that the PSC phenomenon is not just associated with needling but can be perceived when using a mock laser.

Prolactin

During an oral glucose tolerance test (OGTT) glucose and insulin levels were measured in 26 patients with prolactin-producing pituitary tumours without growth hormone excess. Basal glucose and insulin levels did not differ from the values of an age-matched control group. After glucose load the hyperprolactinaemic patients showed a decrease in glucose tolerance and a hyperinsulinaemia. Bromocriptine (CB 154), which suppressed PRL, improved glucose tolerance and decreased insulin towards normal in a second OGTT. — Human PRL or CB 154 had no significant influence on insulin release due to glucose in the perfused rat pancreas. — These findings suggest a diabetogenic effect of PRL. CB 154 might be a useful drug in improving glucose utilization in hormone-active pituitary tumours

The Ethics of Corporate Governance

How should corporate directors determine what is the right decision? For at least the past 30 years the debate has raged as to whether shareholder value should take precedence over corporate social responsibility when crucial decisions arise. Directors face pressure, not least from ethical investors, to do the good thing when they seek to make the right choice. Corporate governance theory has tended to look to agency theory and the need of boards to curb excessive executive power to guide directors' decisions. While useful for those purposes, agency theory provides only limited guidance. Supplementing it with the alternatives - stakeholder theory and stewardship theory - tends to put directors in conflict with their legal obligations to work in the interests of shareholders. This paper seeks to reframe the discussion about corporate governance in terms of the ethical debate between consequential, teleological approaches to ethics and idealist, deontological ones, suggesting that directors are - for good reason - more inclined toward utilitarian judgments like those underpinning shareholder value. But the problems with shareholder value have become so great that a different framework is needed: strategic value, with an emphasis on long-term value creation judged from a decidedly utilitarian standpoint

Protocol for Acupuncture Treatment of Lateral Elbow Pain: A Multisite Randomised Controlled Trial in China, Hong Kong, Australia, and Italy

© 2016 Christopher Zaslawski et al. Background. Lateral elbow pain is one of the most common musculoskeletal pains associated with the upper limb and has an estimated population incidence of 1-3%. Methods/Design. This study protocol is for a multisite randomised controlled study and is designed to evaluate the clinical efficacy of acupuncture in the treatment of chronic (over three months' duration) lateral elbow pain. Four study sites, in the People's Republic of China, Hong Kong, Italy, and Australia, will recruit 24 participants each. A total of 96 participants will be randomised to either an acupuncture group or a sham laser control group. The primary outcome measure will be the Disabilities of Arm, Shoulder, and Hand questionnaire with secondary outcome measures of Pain-Free Grip Strength Test, Muscle Tension Test, and a pain visual analogue scale. Discussion. Key features for conducting a multisite international acupuncture randomised clinical trial have been detailed in this protocol. Trial Registration.
