The influence of family environment on dissociation in pediatric injury patients

Emerging support for the roles of both early trauma and family environment in the development of dissociative symptomatology is complicated by the frequent co-occurrence of dysfunctional family environments and childhood maltreatment. The present investigation prospectively examined the influence of family environment on dissociative symptom course in 82 youths (8–18 years) who experienced accidental injury. The primary caretaker reported on six-week family environment (including family cohesion and adaptability) and on youth symptoms of dissociation prior to injury at six weeks and at six months; dissociation prior to injury was assessed via retrospective parent account at the six-week timepoint. Adolescents (aged 11–18) also reported on their own dissociative symptoms at six weeks. Latent growth modeling indicated that youth in more cohesive family environments evidenced decreased symptoms of dissociation at the six-week intercept (z = −2.80). Furthermore, parent income was negatively related to symptoms of dissociation at intercept (z = −1.96) and parent education was associated with a decrease in youth dissociation symptoms over time (z = −2.57). The present findings provide support for the importance of acute family environment in pediatric post-injury adjustment and further highlight the importance of parent resources, including income and education, in post-injury adjustment.
A half-bridge inverter based active power quality compensator for electrified railways

This paper proposes a new half-bridge inverter based active power quality compensator (APQC) for electrified railways with a three-leg inverter. The first-leg is connected to α-phase, and the second-leg is connected to β-phase. The midpoint of two capacitors on the dc side is connected to the ground line. These two half-bridge inverters exchange the active power on the each feeder each other through two dc capacitors, and compensate the negative-sequence and harmonic components of the load currents. The third-leg performs a dc voltage balancer for two dc capacitors connected to the half-bridge inverters. Thus the balanced and sinusoidal source voltages and currents factor are attained on the primary side of the Scott transformer with the balanced dc capacitor voltages. The basic principle of the proposed half-bridge inverter based APQC is discussed in detail, and then confirmed by digital computer simulation using PSIM software. Simulation results demonstrate that the balanced source currents with the unity power factor are obtained on the primary side the Scott transformer in the traction substation systems balancing two dc capacitor voltages.
The effects of a transfer to new premises on patients' perceptions of service quality in a general hospital in Greece

Many researchers have examined the service quality of healthcare organisations, but none of them examined the effects of a transfer to new premises on service quality. The purpose of this study is to explore the effects of new facilities on patients' perception of the quality of services in the General Hospital of Katerini in Greece. To do so, we compare three different researches about service quality and used the gap analysis method and paired – samples t-test to define if perceptions and expectations of service quality among the quality dimensions were significant (p < .05). The transfer to new premises and new medical equipment have substantially improved the five dimensions but not to the extent that they could be considered a complete service improvement. The results confirmed all of our five research hypotheses. The transfer to new premises most affects the ‘tangibles’ dimension. At the same time, the remaining four dimensions of service quality were, on the whole, positively influenced.
Factors related to the organizational and professional commitment of internal auditors

Much has been written about organizational and professional commitment; however, little has been directed toward the internal auditing profession. Given the recent decline of Enron, WorldCom, etc., and new regulations (eliminating the outsourcing of internal auditing) the internal auditor is likely to gain more responsibility in the firm. It will benefit employers and the professions to better understand what leads the internal auditor to become committed to his/her organization and profession. This study addresses that need. Results show that factors influencing organizational commitment are different from those influencing professional commitment. Multiple linear regression models show strong relationships between organizational commitment and job meaningfulness; however, task identity has a strong positive relationship with professional commitment while gender and organization size (services sector and internal auditor certification) have a positive (negative) influence on organizational commitment. Internal auditor certification also shows a positive impact on professional commitment. Management implications of these results are discussed.
Thread Reconstruction in Conversational Data using Neural Coherence Models

Discussion forums are an important source of information. They are often used to answer specific questions a user might have and to discover more about a topic of interest. Discussions in these forums may evolve in intricate ways, making it difficult for users to follow the flow of ideas. We propose a novel approach for automatically identifying the underlying thread structure of a forum discussion. Our approach is based on a neural model that computes coherence scores of possible reconstructions and then selects the highest scoring, i.e., the most coherent one. Preliminary experiments demonstrate promising results outperforming a number of strong baseline methods.
Power-rail ESD clamp circuit with hybrid-detection enhanced triggering in a 65-nm, 1.2-V CMOS process

A power-rail electrostatic discharge clamp circuit with transient and static hybrid-detection enhanced triggering is proposed in this work. By skillfully co-optimizing the driving paths of both transient and static detection networks, the proposed circuit achieves a clamp device transient response time over 2 times longer than its RC time constant, which endows the proposed circuit with both promoted area-efficiency and safe clamping behaviors. Besides, the proposed circuit effectively combines the advantages of transient and static ones with tiny leakage current penalties. All investigated circuits are fabricated in a 65-nm CMOS process using 1.2-V thin-oxide devices. Simulation and test results are discussed in detail in this work to validate the proposed circuit.
Earnings, Occupations and Labour Market Experience in Australia; 1997-2005

This paper examines the relative importance of different types of labour market experience in the determination of earnings across occupations. Specifically, the paper estimates the returns to general experience, firm tenure and occupational tenure for each occupation within the Australian Standard Classification of Occupations (ASCO) in 1997 and 2005. The paper finds that there is an important role for each form of labour market experience. General experience tends to dominate the other forms of labour market experience, both statistically and numerically. While not as important as general experience, wages nevertheless rise with firm tenure in most occupations. Occupational tenure is only important in a small subset of occupations, mainly for Professionals and Tradespeople. There is also evidence that the return to occupational tenure increased significantly for Tradespeople and for Intermediate Transport and Production Workers between 1997 and 2005.
The Pathogenesis-Related Maize Seed (PRms) Gene Plays a Role in Resistance to Aspergillus flavus Infection and Aflatoxin Contamination

Aspergillus flavus is an opportunistic plant pathogen that colonizes and produces the toxic and carcinogenic secondary metabolites, aflatoxins, in oil-rich crops such as maize (Zea mays ssp. mays L.). Pathogenesis-related (PR) proteins serve as an important defense mechanism against invading pathogens by conferring systemic acquired resistance in plants. Among these, production of the PR maize seed protein, ZmPRms (AC205274.3_FG001), has been speculated to be involved in resistance to infection by A. flavus and other pathogens. To better understand the relative contribution of ZmPRms to A. flavus resistance and aflatoxin production, a seed-specific RNA interference (RNAi)-based gene silencing approach was used to develop transgenic maize lines expressing hairpin RNAs to target ZmPRms. Downregulation of ZmPRms in transgenic kernels resulted in a ∼250–350% increase in A. flavus infection accompanied by a ∼4.5–7.5-fold higher accumulation of aflatoxins than control plants. Gene co-expression network analysis of RNA-seq data during the A. flavus-maize interaction identified ZmPRms as a network hub possibly responsible for regulating several downstream candidate genes associated with disease resistance and other biochemical functions. Expression analysis of these candidate genes in the ZmPRms–RNAi lines demonstrated downregulation (vs. control) of a majority of these ZmPRms-regulated genes during A. flavus infection. These results are consistent with a key role of ZmPRms in resistance to A. flavus infection and aflatoxin accumulation in maize kernels.
Factors Associated with Differences in the Magnitude of Abnormal Returns Around NYSE Versus NASDAQ Firms' Earnings Announcements

This study provides an explanation for the 'exchange effect' puzzle documented in prior accounting research. Grant (1980) finds that the magnitude of earnings announcement week abnormal returns is higher, on average, for firms traded over-the-counter than for NYSE firms. Atiase (1987) shows that this incremental 'exchange effect' persists even after controlling for firm size. We investigate potential explanations for this incremental exchange effect. We first show that even after controlling for differences in firm size, Nasdaq firms have less rich information environments and enjoy greater growth opportunities than NYSE firms. We then investigate whether differential predisclosure information environments and/or growth opportunities can explain the incremental exchange effect. The results indicate that although the absolute magnitude of the earnings announcement-related abnormal returns is inversely related to proxies for the amount of predisclosure information, the incremental exchange effect cannot be explained by differences in the predisclosure information environment. In contrast, after controlling for differences in growth opportunities across NYSE versus Nasdaq firms, and investors' heightened sensitivity to Nasdaq firms' growth opportunities in particular, there is no significant incremental exchange effect (whether or not we control for predisclosure information). These results suggest that the incremental exchange effect puzzle documented in prior research is more likely to reflect growth-related phenomena than differences in the predisclosure information environment.

Mammography screening is harmful and should be abandoned

Mammography screening is controversial and systematic reviews conducted by organisations with no conflicts of interest, such as the Nordic Cochrane Centre, theUSand theCanadianTaskForces, the Independent UK Panel and the Swiss Medical Board have found substantial problems with the randomised trials. It is therefore difficult to know what the true effect is. An additional problem is that trials are old. All but one started between 1963 and 1982, and back then, women did not receive much adjuvant therapy such as anti-hormonal treatment and chemotherapy. The introduction of effective drugs has reduced substantially the potential for screening to work. Screening can have no effect for women who, thanks to improved therapy, now live so much longer that they die of a heart attack before their breast cancer becomes life-threatening. Furthermore, as the effect of adjuvant therapy is largely independent of nodal status and other tumour characteristics, it works whether or not the cancer is detected ‘early’. An additional, crucial problem is that the assessment of cause of death is biased in favour of screening. I documented this in our Cochrane review, and more recently also in a meta-regression analysis of the trials (Figure 1). One would expect to see the greatest reduction in breast cancer mortality in those trials that were most effective in lowering the rate of nodepositive cancers in the screened group. This was indeed the case, but the regression predicts that a screening effectiveness of zero (i.e. the rate of node-positive cancers is the same in the screened group as in the control group) results in a 16% reduction in breast cancer mortality (95% confidence interval 9–23% reduction). This could only happen if there is bias, and further analyses showed that assessment of cause of death and of the number of cancers in advanced stages were both biased in favour of screening.
How Stable is the Savings-led Growth Hypothesis in Malaysia? The Bootstrap Simulation and Recursive Causality Tests

The purpose of this study is to empirically investigate the vindication of the savings-led growth hypothesis for the Malaysian economy with the long-run TYDL version of the Granger causality test—Toda and Yamamoto (1995) and Dolado and Lütkepohl (1996). This study used the quarterly sample from 1970:Q1 to 2008:Q4. The recursive regression procedure will also incorporate into the TYDL causality test to measure the stability of the savings-led growth hypothesis in the long-run. Our empirical results support that the savings-led growth hypothesis is a long-run phenomenon and stable over time. Therefore, the Malaysian dataset supports the endogenous growth theory.

Ultrastructural study of Listeria monocytogenes entry into cultured human colonic epithelial cells

Evidence that Listeria monocytogenes enters Caco-2 cells through the apical surface is presented. Attachment of bacteria to host cells seems to induce modifications of microvilli which are either in direct contact with the bacterial surface or in close vicinity, resulting in the formation of lamellipodia involved in the cellular uptake of the bacteria. Such modifications are not induced by L. monocytogenes SLCC 53, which carries a deletion in the prfA gene, although attachment of this mutant to Caco-2 cells occurs. Listeria innocua does not attach well to Caco-2 cells and also fails to cause structural alterations of the microvilli. Treatment of confluent monolayers of Caco-2 cells with ethylene glycol-bis(beta-aminoethyl ether)- N,N,N1,N1-tetraacetic acid (EGTA), which disrupts intercellular junctions, greatly reduced the uptake of Listeria cells. Attachment and invasion of L. monocytogenes was not accompanied by accumulation of filamentous actin around the entering bacterial cell.
Institutional Ownership, Volatility and Dividends

We find that the sign of the correlation between institutional ownership and volatility depends on the firm's dividend policy: institutional ownership is negatively (positively) related to volatility among non-dividend (dividend) paying stocks. The empirical results are consistent with an interaction between institutional preference for low volatility and the tendency of higher levels of institutional ownership to increase volatility through their trading behavior. This result is robust to many control variables and possible endogeneity concerns. Supporting our conjecture that institutions herd on dividend signals we find that the correlation between turnover and institutional ownership is higher for dividend paying stocks, and that the positive correlation between turnover and institutional ownership is higher on dividend declaration days. Finally, we also find that the level of institutional ownership drops following an increase in volatility for both dividend payers and non-payers, and that volatility rises following increased institutional ownership for dividend paying stocks.
An evaluation of relations among antisocial behavior, psychopathic traits, and alcohol problems in incarcerated men.

BACKGROUND The association between antisocial behavior and alcohol problems is well established, but the role that psychopathic traits and other factors such as drinking patterns and motives and family history play in this relationship has not been subjected to much empirical scrutiny. METHODS A large sample (n=329) of male Federal Correctional Institution inmates participated in structured interviews designed to permit diagnosis of antisocial personality disorder and to assess facets of psychopathic personality as defined by the Hare Psychopathy Checklist-Revised. Prisoners also completed self-report questionnaires that addressed alcohol use, drinking problems, motives for drinking, and paternal alcoholism history. RESULTS Analyses revealed that the relation between antisocial behavior and alcohol problems was moderated by scores on the emotional detachment component of psychopathy, and that self-descriptions of drinking for the purpose of coping with negative emotions mediated the positive relation between antisociality and self-reported alcohol problems. CONCLUSIONS These findings highlight complexities in the link between antisociality and drinking problems and encourage consideration of distinct facets of psychopathy to enhance understanding of it. They further suggest possible mechanisms (e.g., paternal alcoholism history, coping motives) that may contribute to the development and maintenance of alcohol problems in criminal populations.
Histological characterization of the early stages of bone morphogenetic protein-induced osteogenesis.

On the basis of currently available knowledge, we hypothesize that the initial bone formation, as induced by bone morphogenetic protein (BMP), is influenced by the chemical composition and three-dimensional spatial configuration of the used carrier material. Therefore, in the current study, the osteoinductive properties of porous titanium (Ti) fiber mesh with a calcium phosphate (Ca-P) coating (Ti-CaP), insoluble bone matrix (IBM), fibrous glass membrane (FGM), and porous particles of hydroxy apatite (PPHAP) loaded with rhBMP-2 were compared in a rat ectopic assay model at short implantation periods. Twelve Ti-CaP, 12 IBM, 12 FGM, and 12 PPHAP implants, loaded with rhBMP-2, were subcutaneously placed in 16 Wistar King rats. The rats were sacrificed at 3, 5, 7, and 9 days post-operative, and the implants were retrieved. Histological analysis demonstrated that IBM and Ti-CaP had induced ectopic cartilage and bone formation by 5 and 7 days, respectively. However, in PPHAP, bone formation and cartilage formation were seen together at 7 days. At 9 days, in Ti-CaP, IBM, and PPHAP, cartilage was seen together with trabecular bone. At 9 days, in FGM, only cartilage was observed. Quantitative rating of the tissue response, using a scoring system, demonstrated that the observed differences were statistically significant (Wilcoxon rank sum test, p < 0.05). We conclude that IBM, CaP-coated Ti mesh, FGM, and PPHAP provided with rhBMP-2 can indeed induce ectopic bone formation with a cartilaginous phase in a rat model at short implantation periods. Considering the different chemical composition and three-dimensional spatial configuration of the carrier materials used, these findings even suggest that endochondral ossification is present in rhBMP-2-induced osteogenesis, even though the amount of cartilage may differ.
How To Do Safe Sternal Reentry and the Risk Factors of Redo Cardiac Surgery: A 21‐Year Review with Zero Major Cardiac Injury

Abstract Objectives: Resternotomy is a common part of cardiac surgical practice. Associated with resternotomy are the risks of cardiac injury and catastrophic hemorrhage and the subsequent elevated morbidity and mortality in the operating room or during the postoperative period. The technique of direct vision resternotomy is safe and has fewer, if any, serious cardiac injuries. The technique, the reduced need for groin cannulation and the overall low operative mortality and morbidity are the focus of this restrospective analysis. Methods: The records of 495 patients undergoing 546 resternotomies over a 21‐year period to January 2000 were reviewed. All consecutive reoperations by the one surgeon comprised patients over the age of 20 at first resternotomy: M:F 343:203, mean age 57 years (range 20 to 85, median age 60). The mean NYHA grade was 2.3 [with 67 patients (I), 273 (II), 159 (III), 43 (IV), and 4 (V classification)] with elective reoperation in 94.6%. Cardiac injury was graded into five groups and the incidence and reasons for groin cannulation estimated. The morbidity and mortality as a result of the reoperation and resternotomy were assessed. Results: The hospital/30 day mortality was 2.9% (95% CI: 1.6%‐4.4%) (16 deaths) over the 21 years. First (481), second (53), and third (12) resternotomies produced 307 uncomplicated technical reopenings, 203 slower but uncomplicated procedures, 9 minor superficial cardiac lacerations, and no moderate or severe cardiac injuries. Direct vision resternotomy is crystalized into the principle that only adhesions that are visualized from below are divided and only sternal bone that is freed of adhesions is sewn. Groin exposure was never performed prophylactically for resternotomy. Fourteen patients (2.6%) had such cannulation for aortic dissection/aneurysm (9 patients), excessive sternal adherence of cardiac structures (3 patients), presurgery cardiac arrest (1 patient), and high aortic cannulation desired and not possible (1 patient). The average postop blood loss was 594 mL (95% CI:558–631) in the first 12 hours. The need to return to the operating room for control of excessive bleeding was 2% (11 patients). Blood transfusion was given in 65% of the resternotomy procedures over the 21 years (mean 854 mL: 95% Cl 765–945 mL) and 41% over the last 5 years. Conclusions: The technique of direct vision resternotomy has been associated with zero moderate or major cardiac injury/catastrophic‐hemorrhage at reoperation. Few patients have required groin cannulation. In the postoperative period, there was acceptable blood loss, transfusion rates, reduced morbidity, and moderate low mortality for this potentially high risk group.
The Management of Nonsyndromic, Isolated Sagittal Synostosis

Aim:Isolated sagittal synostosis is the commonest form of craniosynostosis. The reasons for surgery are to normalize the head shape and to increase the cranial volume, thus reducing the risk of raised intracranial pressure and allowing for normal brain development. It has been suggested that sagittal synostosis may impair neuropsychological development. This systematic review appraised the literature on the management of sagittal synostosis. Methods:A literature search was performed with the assistance of a professional librarian. Studies selected had to satisfy the criteria set by PICO (patients, intervention, comparison, and outcome). Cranial index and neuropsychological outcome were used as outcome measures. MINORS was used to assess the methodological quality of the selected articles. A score of 75% was deemed to be of satisfactory quality, and the quality of the evidence from the selected studies was graded using the GRADE system. Results:One hundred forty-eight articles were initially identified. Only 6 articles fulfilled the PICO criteria and scored a minimum of 75% on MINORS. Four studies compared 1 technique to another with documented cranial indices. Two studies compared 1 group to another and assessed the neuropsychological development. According to GRADE, the quality of evidence was deemed to be very low. Conclusions:This systematic review assessed cranial index and neuropsychological outcome following surgery for isolated, nonsyndromic sagittal synostosis. The quality of the evidence in the published literature was noted to be of very low quality. There is a need for better-designed, prospective studies to guide surgeons involved in management of sagittal synostosis.
