Still living in a war zone: Perceived health and wellbeing of partners of Vietnam veterans attending partners' support groups in New South Wales, Australia

Post-traumatic stress disorder (PTSD) in veterans is well documented, less so the long-term impact on the health of their partners and families. The perceived health and wellbeing of women partners of Australian Vietnam veterans who were members of partners of veterans support groups is reported. This qualitative study used data from 76 participants in 10 focus groups in metropolitan, regional, and rural and remote areas of New South Wales (NSW). The data were tape-recorded, transcribed and thematically analysed using constant comparison methods. The impact of living with a partner with war-related PTSD appears to be significant and ongoing with women drawing parallels to living in a war zone. The biggest negative impact was on their mental health. They felt burdened as carers and struggled to find explanations for their husbands' problems. Support groups were very helpful. There are implications for partners of veterans who have returned from active military duty and from peacekeeping in current conflicts.
Mitigation of lead free solder aging effects using doped SAC-X alloys

The microstructure, mechanical response, and failure behavior of lead free solder joints in electronic assemblies are constantly evolving when exposed to isothermal aging and/or thermal cycling environments. In our prior work on aging effects, we have demonstrated that large degradations occur in the material properties (stiffness and strength) and creep behavior of Sn-Ag-Cu (SAC) lead free solders during aging. These effects are universally detrimental to reliability and are exacerbated as the aging temperature and aging time increases. Conversely, changes due to aging are relatively small in conventional Sn-Pb solders. In our current work, we are exploring several doped SAC-X alloys in an attempt to reduce the aging induced degradation of the material behavior of SAC solders. The doped materials are lead free SAC solders that have been modified by the addition of small percentages of one or more additional elements (X). Using dopants (e.g. Bi, In, Ni, La, Mg, Mn, Ce, Co, Ti, Zn, etc.) has become widespread to enhance shock/drop reliability, wetting, and other properties; and we have extended this approach to examine the ability of dopants to reduce the effects of aging and extend thermal cycling reliability. In this paper, we concentrate on presenting the results for SACX0307 (Sn-0.3Ag-0.7Cu-0.1Bi). This alloy is often referred to as SAC-X, where X is 0.1%Bi, and the enhancement of aging resistance for the doped lead free solder was explored. Comparisons were made to the responses of SAC105 and SAC205, which served as the low silver content reference SAC alloys. The effects of aging on mechanical behavior have been examined by performing stress-strain and creep tests on solder samples that were aged for various durations (0-6 months) at room temperature (25°C), and several elevated temperatures (50, 75, 100, and 125°C). Variations of the mechanical and creep properties (elastic modulus, yield stress, ultimate strength, creep compliance, etc.) were observed and modeled as a function of aging time and aging temperature. Our findings show that the doped SAC-X alloys illustrate reduced degradations with aging for all of the aging temperatures considered. Also, the stress-strain and creep mechanical properties of doped solders are better than those of reference solders after short durations of aging. After long term aging, doped solder alloys were found to have more stable behaviors than those of the standard SAC alloys. A parallel microstructure study has shown that less degradation and coarsening of the phases occurs in doped solder materials relative to non-doped solders after severe aging.
The rotatory nystagmus response in children.

The nystagmus pattern obtained by a standardized vestibular stimulation was studied in children from birth to 15 years of age. The speed of the slow component decreased with increasing age. The differences in the speed between the age groups were most pronounced at the beginning of the vestibular test, whereafter they diminished successively. The duration of the nystagmus was shortest in children aged less than 12 months. The nystagmus amplitude and the speed of the fast component decreased with increasing age; the differences between the age groups at the beginning were the same as at the end of the vestibular response. The nystagmus intensity was classified in two parts: one depending on the peripheral, vestibular activity and the other on the central activity. According to this classification, the small children in relation to the older ones had a high peripheral and a low central nystagmus intensity.
Repeated and Time-Correlated Morphological Convergence in Cave-Dwelling Harvestmen (Opiliones, Laniatores) from Montane Western North America

Background Many cave-dwelling animal species display similar morphologies (troglomorphism) that have evolved convergent within and among lineages under the similar selective pressures imposed by cave habitats. Here we study such ecomorphological evolution in cave-dwelling Sclerobuninae harvestmen (Opiliones) from the western United States, providing general insights into morphological homoplasy, rates of morphological change, and the temporal context of cave evolution. Methodology/Principal Findings We gathered DNA sequence data from three independent gene regions, and combined these data with Bayesian hypothesis testing, morphometrics analysis, study of penis morphology, and relaxed molecular clock analyses. Using multivariate morphometric analysis, we find that phylogenetically unrelated taxa have convergently evolved troglomorphism; alternative phylogenetic hypotheses involving less morphological convergence are not supported by Bayesian hypothesis testing. In one instance, this morphology is found in specimens from a high-elevation stony debris habitat, suggesting that troglomorphism can evolve in non-cave habitats. We discovered a strong positive relationship between troglomorphy index and relative divergence time, making it possible to predict taxon age from morphology. Most of our time estimates for the origin of highly-troglomorphic cave forms predate the Pleistocene. Conclusions/Significance While several regions in the eastern and central United States are well-known hotspots for cave evolution, few modern phylogenetic studies have addressed the evolution of cave-obligate species in the western United States. Our integrative studies reveal the recurrent evolution of troglomorphism in a perhaps unexpected geographic region, at surprisingly deep time depths, and in sometimes surprising habitats. Because some newly discovered troglomorphic populations represent undescribed species, our findings stress the need for further biological exploration, integrative systematic research, and conservation efforts in western US cave habitats.
The importance of natural change in planning school-based intervention for children with Developmental Language Impairment (DLI)

Some reports suggest that there is an increase in the number of children identified as having developmental language impairment (Bercow, 2008). yet resource issues have meant that many speech and language therapy services have compromised provision in some way. Thus, efficient ways of identifying need and prioritizing intervention are required. Despite this, children’s natural change is rarely formally considered when intervention planning. The role of age, gender and non-verbal IQ in predicting change has also not always been considered. A longitudinal baseline period is important because it may guide teachers and language therapists towards different therapeutic aims/methods for different groups of children. This study reports on 22 children aged 4–7 identified by teachers as having language difficulties. All children took part in a classroom-based semantic language intervention in two phases, the first led by speech and language therapists (SLTs), followed by a phase led by trained learning support assistants (LSAs). Two Natural Change subgroups were compared: One group showed natural change in language over a six-week period before the intervention ran (n = 11; Baseline Improvers) whilst the other group did not show language change in this non-intervention period (n = 12; Baseline Non-Improvers). The groups were well matched on skills at study entry and differed only on score change without intervention. Language skills were assessed at three subsequent time points: pre-therapy, post-SLT-therapy and post-LSA-therapy. In the group as a whole, significant changes were seen across all language measures except expressive vocabulary. Non-verbal cognitive ability showed no change over time, and did not predict language change. There were important differences in the patterns shown by each subgroup depending on natural change without intervention. Notably, Baseline Non-Improvers changed during intervention more than Baseline Improvers. The results suggest that use of a longitudinal baseline may be useful when planning interventions and deciding where to focus limited resources.
Short- and long-term omeprazole for the treatment and prevention of duodenal ulcer, and effect on Helicobacter pylori.

OBJECTIVE This study analyzes the effect of short- and long-term omeprazole (OM) on duodenal ulcer healing, recurrence, and H. pylori status. METHODS Patients affected by active duodenal ulcer were randomly allocated to treatment with OM 20 mg or 40 mg once daily for 4 wk. Subsequently, patients with healed duodenal ulcer were randomly assigned to one of the following three groups: OM 20 mg once daily for 12 months, OM 20 mg alternate days for 12 months, and no treatment. Endoscopy was performed at entry, at 4 wk, and after 4, 8, and 12 months. Two biopsy specimens from antrum, body, and fundus were taken for histology and search for H. pylori. One hundred and eighty patients with active duodenal ulcer were admitted. Ninety-one were treated with OM 20 mg once daily and 89 with OM 40 mg for 4 wk. RESULTS The results at 4 wk show 92.8% patients healed with OM 20 mg and 95.1% at 40 mg (NS). In the second part of the study, 96 of the patients who healed at 4 wk (45 with OM 20 mg, and 51 with OM 40 mg) entered the long-term study. Thirty-six patients received OM 20 mg daily for 12 months, 35 OM 20 mg on alternate days for 12 months, and 25 patients no treatment. The results show a healing rate of 100%, 100%, and 95% with OM 20 mg daily, of 97%, 95%, and 93% with OM 20 mg on alternate days, and of 81%, 50%, and 40% (p < 0.01) with no treatment at 4, 8, and 12 months, respectively. H. pylori that was found in 97% of patients at entry, at 4 wk was found in 92.8% of patients treated with OM 20 mg and in 97.5% of patients treated with OM 40 mg (NS). In one-third of the patients, H. pylori disappeared from the antrum but was found in the fundus. A 30% reduction in the presence of H. pylori was seen in the group treated with 20 mg daily for 12 months. CONCLUSIONS We conclude that both continuous and alternate-day long-term OM treatment at 20 mg are similarly efficacious in the prevention of duodenal ulcer recurrence. Healing active duodenal ulcers with 20 or 40 mg does not influence subsequent treatment. Long-term OM at 20 mg daily for 12 months suppresses H. pylori temporarily in one-third of the patients. In these patients however, H. pylori reactivates after the end of treatment.
Custodial interrogation: What are the background factors associated with claims of false confession to police?

Abstract The aim of this paper is to investigate the association between an alleged false confession during custodial interrogation and reported adverse life events, substance abuse problems, self-harm behaviour, and previous psychological/psychiatric treatment. A total of 1896 students in further education in Iceland (aged 15 – 24 years), who had reported an experience of police interrogation, completed a detailed questionnaire about their background, substance abuse, and psychological/psychiatric treatment. Of the 1896 participants, 138 (7.3%) claimed to have made a false confession to the police. Out of 27 variables entered into a logistic regression analysis, eight significant predictor variables were identified in the model. These were largely associated with multiple victimisation (e.g., bullying, death of a significant other, being a victim of violence) and substance abuse (i.e., having attended substance abuse treatment, use of LSD). The findings suggest that multiple exposures to unpleasant or traumatic life events are associated with the reporting of false confessions during interrogation.
THE EMERGENT CONCERN OF SEROPOSITIVE STATUS OF HEPATITIS-B VIRUS AND HEPATITIS-C VIRUS IN THE PREGNANT FEMALES ATTENDING A TERTIARY CARE HOSPITAL.

BACKGROUND Viral hepatitis is a global problem affecting millions of people including pregnant females. Viral hepatitis during pregnancy is associated with both maternal and neonatal mortality and morbidity. This study was an attempt to assess the seropositive status of hepatitis-B and C infection among pregnant women in Karachi, Pakistan. METHODS This cross sectional observational study was conducted at Sir Syed College of Medical Sciences and Trust Hospital, Karachi from January to September 2012. Patients were recruited by consecutive sampling. At the booking visit, blood was drawn and tested for HbsAg and Anti HCV by Eliza method. RESULTS Among the screened population, 2% were reactive for HBV and 13.3% were found reactive for HCV. All HbsAg and HCV positive pregnant patients had one or more than one delivery. CONCLUSION In our study sample, high frequency of HBV and HCV is suggestive of the importance of antenatal screening of these viral diseases, which has impact on the mother as well as the new born baby. HCV was more common as compared to HBV which is quite alarming.
DCOPF based optimal transmission capacity reservation for FRR exchange using implicit and sequential market clearance

The European power system is experiencing a massive renewable penetration, increased meshing of the grid, and electricity market integration. This calls for market design options that can cope with the challenges resulting from the ongoing developments. Based on a DC optimal power flow (DCOPF) formulation, this paper analyzes the impact of market design options on the optimal transmission allocation for Frequency Restoration Reserves (FRR) exchange in the Northern Europe power markets. We consider implicit and sequential electricity market clearance options and assess the findings according to the total costs, optimal transmission capacity allocation, and regional FRR procurement. The results show that, as a result of increased market efficiency obtained by applying the implicit market clearance option, it is less expensive, and results in comparatively lower transmission capacity allocation from the Nordic system to the interconnected regions.
The Rhetoric of a Reform: The Construction of ‘Public’, ‘Management’ and the ‘New’ in Norwegian Education Reforms of the 1990s

This article presents a critical rhetorical analysis of the governing and reform ideology of the Norwegian school system of the 1990s. It uses Karl Popper's The Open Society and its Enemies as a critical resource in the reading of the reforms, and discusses some of the consequences of the regime's models of leadership and public management for important pedagogical qualities of the school system.
Systematic review of discography as a diagnostic test for spinal pain: an update.

BACKGROUND The intervertebral disc has been implicated as an etiology of chronic spine pain based on clinical, basic science, and epidemiological research. There is currently no way to determine with absolute certainty whether or not the disc is a spinal pain generator. At our current level of understanding, discography is thought of as the best tool to evaluate disc-related pain. STUDY DESIGN A systematic review. OBJECTIVE To systematically assess the diagnostic accuracy of discography with respect to chronic spinal pain. METHODS A systematic review of the literature was performed to assess the diagnostic accuracy of discography with respect to chronic spinal pain. Study inclusion/exclusion criteria were based on the modern practice of discography. Selected studies were then subjected to two rating instruments for diagnostic accuracy studies (AHRQ and QUADAS). Specific data were then culled from these studies and tabulated. Evidence was then classified into five levels: conclusive, strong, moderate, limited, or indeterminate. RESULTS Evidence is strong for the diagnostic accuracy of discography as an imaging tool. Evidence is also strong for the ability of discography to evoke pain. There is strong evidence supporting the role of discography in identifying that subset of patients with lumbar discogenic pain. There is moderate evidence supporting the role of discography in identifying a subset of patients with cervical discogenic pain. There is limited evidence supporting the role of discography in identifying a subset of patients with thoracic discogenic pain. CONCLUSION Discography is a useful imaging and pain evaluation tool in identifying a subset of patients with chronic spinal pain secondary to intervertebral disc disorders.
Situational Strength Cues from Social Sources at Work: Relative Importance and Mediated Effects

Situational strength is considered one of the most important situational forces at work because it can attenuate the personality–performance relationship. Although organizational scholars have studied the consequences of situational strength, they have paid little attention to its antecedents. To address this gap, the current study focused on situational strength cues from different social sources as antecedents of overall situational strength at work. Specifically, we examined how employees combine situational strength cues emanating from three social sources (i.e., coworkers, the immediate supervisor, and top management). Based on field theory, we hypothesized that the effect of situational strength from coworkers and immediate supervisors (i.e., proximal sources of situational strength) on employees' perceptions of overall situational strength on the job would be greater than the effect of situational strength from the top management (i.e., the distal source of situational strength). We also hypothesized that the effect of situational strength from the distal source would be mediated by the effects of situational strength from the proximal sources. Data from 363 full-time employees were collected at two time points with a cross-lagged panel design. The former hypothesis was supported for one of the two situational strength facets studied. The latter hypothesis was fully supported.
Is FOXP3 a bona fide marker for human regulatory T cells?

FOXP3 is a specific marker for naturally occurring regulatory T cells (nTreg). FOXP3 expression is correlated with development and function of nTreg. Recent evidence suggests that, upon activation, human effector T (Teff) cells and type 1 regulatory T (Tr1) cells can express FOXP3, albeit transiently. While the role of transient FOXP3 expression in Teff cells is poorly understood, it is becoming clear that it does not correlate with suppressor function. Furthermore, FOXP3‐independent mechanisms, mediated by IL‐10, contribute to the induction and suppressor functions of Tr1 cells.
Canine echinococcosis in Turkana (north–western Kenya): a coproantigen survey in the previous hydatid-control area and an analysis of risk factors

Abstract A study of Echinococcus granulosus infection in dogs, with risk-factor analysis, was carried out in the endemic area of northern Turkana district, Kenya, using necropsy on 42 strays and a coproantigen-ELISA survey of 161 owned animals. During the post-mortem examinations, 14 (33%) of the necropsied dogs were found infected with E. granulosus, with a mean burden of 540 worms (range=two to 4080 worms). The 26 necropsied dogs that came from the north–western Lokichoggio division — an area where, from 1983 to 1997, there had been a continuous programme of hydatid control — showed a similar prevalence of infection to the other dogs (34.6%) but a significantly lower mean burden, of 53 worms (range=two to 300). Forty-two (26%) of the animals tested for Echinococcus coproantigen were found positive. Although the dogs from the Lokichoggio division were more likely to be coproantigen-positive (29%) than those from the central Kakuma division (20%) or the north–eastern division (18%), the differences were not statistically significant. In questionnaire-based interviews, the owners of the dogs tested for coproantigens were asked about possible risk factors for canine infection with E. granulosus. Women were found to have twice the level of contact with dogs as men. The results of a univariate analysis of the dog-owners' responses revealed six factors that appeared to be significantly associated with a coproantigen-positive dog: non-restraint of the dog (P<0.001); dog fed on raw offal (P<0.001); the improper disposal of slaughter offal (P<0.001); the dog-owner's lack of knowledge about the transmission of echinococcosis (P=0.001); the dog not receiving anthelmintic treatment (P=0.003); and dog age ≤5 years (P=0.01). The results of a multivariate analysis confirmed that lack of dog restraint, access to raw offal, and young age of the dog (≤5 years) each significantly increased the risk of coproantigen positivity (P, 0.005). Dogs that scavenged from cooking pots, were used to clean babies, had access to the inside of houses, and/or slept indoors appeared, however, to be at no increased risk of coproantigen positivity. The present results are discussed in relation both to older information on the epidemiology and role of human behaviour in the transmission of E. granulosus in Turkana, and the effects of the hydatid-control programme that ran continuously in the north–western division of Turkana between 1983 and 1997.
Old and New Stories: Revelations from Functional Analysis of the Bovine Mammary Transcriptome during the Lactation Cycle

The cow mammary transcriptome was explored at −30, −15, 1, 15, 30, 60, 120, 240, and 300 d relative to parturition. A total of 6,382 differentially expressed genes (DEG) at a false discovery rate ≤0.001 were found throughout lactation. The greatest number of DEG (>3,500 DEG) was observed at 60 and 120 d vs. −30 d with the largest change between consecutive time points observed at −15 vs. 1 d and 120 vs. 240 d. Functional analysis of microarray data was performed using the Dynamic Impact Approach (DIA). The DIA analysis of KEGG pathways uncovered as the most impacted and induced ‘Galactose metabolism’, ‘Glycosylphosphatidylinositol (GPI)-anchor biosynthesis’, and ‘PPAR signaling’; whereas, ‘Antigen processing and presentation’ was among the most inhibited. The integrated interpretation of the results suggested an overall increase in metabolism during lactation, particularly synthesis of carbohydrates and lipid. A marked degree of utilization of amino acids as energy source, an increase of protein export, and a decrease of the protein synthesis machinery as well cell cycle also were suggested by the DIA analysis. The DIA analysis of Gene Ontology and other databases uncovered an induction of Golgi apparatus and angiogenesis, and the inhibition of both immune cell activity/migration and chromosome modifications during lactation. All of the highly-impacted and activated functions during lactation were evidently activated at the onset of lactation and inhibited when milk production declined. The overall analysis indicated that the bovine mammary gland relies heavily on a coordinated transcriptional regulation to begin and end lactation. The functional analysis using DIA underscored the importance of genes associated with lactose synthesis, lipid metabolism, protein synthesis, Golgi, transport, cell cycle/death, epigenetic regulation, angiogenesis, and immune function during lactation.
