The role of perceived parental socialization practices in school adjustment among Norwegian upper secondary school students.

BACKGROUND Lack of adjustment or school failure is a concern to educators, educational and school psychologists as well as parents, but few studies have focused on school adjustment during late adolescence. Moreover, studies have yet to explore associations between parenting and school adjustment among upper secondary school students. AIM The primary objective of this study is to explore the relative and unique influence of parental support, behavioural control and psychological control (overprotection and autonomy granting) in school adjustment among upper secondary school students. SAMPLE The sample consisted of 564 students (15-18 years of age) in vocational and general educational courses from one upper secondary school in western Norway. METHOD The study was conducted as a survey. All data were based on adolescent reports, except for absence data, which were provided by the school. RESULTS The results showed that perceived parental practices accounted for moderate, but statistically significant amounts of variance in different aspects of school adjustment. CONCLUSIONS The findings indicate that perceived parental socialization practices are only moderately associated with school adjustment among upper secondary school students. This probably reflects the fact that the influence of specific parenting practices declines as children and young adolescents mature into late adolescent students.
Productivity Shocks in a Union‐Duopoly Model

We consider an industry where firms are asymmetric in terms of productivity. Wages and employment are determined at the firm-level and are the result of sequential bargaining between unions and firms, with wages being negotiated first. We characterise the equilibrium and compare the outcomes in the two firms (wages, employment and surplus of all economic agents). A productivity shock affecting the most efficient firm is socially desirable, by increasing the surplus of consumers, workers and firms. The same may not be true when the productivity shock affects the least efficient firm. In this case, the consumers’ gain may not be enough to outweigh the losses in aggregate worker surplus and in the industry profit.
Awareness and use of folic acid among reproductive age and pregnant women.

OBJECTIVE Folic acid supplementation during the pre-conception period and first trimester of pregnancy reduces the incidence of neural tube defects (NTDs). In this study, our aim is to investigate knowledge and use of folic acid among women attending our clinic. MATERIAL AND METHODS Between January 2012 and June 2012, 817 participants, consisting of 345 pregnant and 472 non-pregnant women, were enrolled in this survey. A questionnaire including socio-demographic information, knowledge and use of folic acid was applied. RESULTS 48.2% of participants were aware of folic acid for the prevention of congenital anomalies. Knowledge and use of folic acid increase with socio-economic status and educational level. Participants who were already knowledgeable about folic acid cited health care professionals as common sources of information. Although 88.2% of the pregnancies were planned among the currently pregnant women, only 14.2% of them stated that they had used folic acid in the pre-conception period. The use of folic acid during the first trimester among pregnant women was 48.6%. Furthermore, 18.4% of participants had not used folic acid and 29.3% of them had not remembered whether they had or not. Even though 94.4% of health care professionals had heard about folic acid, 28.3% reported that they had used folic acid before pregnancy. CONCLUSION It is thought that there is a relatively high incidence of NTD in Turkey, which is due to inadequate information about NTDs and the use of folic acid. Primarily health care professionals such as midwives, nurses and family physicians should aim to inform all reproductive age women about folic acid for the prevention of NTDs, who should be encouraged to take the supplement when planning pregnancy.
Lung deposition of nebulised pentamidine in children.

BACKGROUND: Nebulised pentamidine is effective for preventing Pneumocystis carinii pneumonia in adults with acquired immunodeficiency syndrome. The nebuliser dose required to produce equivalent lung concentrations of pentamidine in children is unknown. This study was performed to measure pulmonary pentamidine deposition in children and to relate this to age, ventilation pattern, and body size. METHODS: Nebulised pentamidine (50 mg in 6 ml saline) was administered to 12 children (including one with lymphocytic interstitial pneumonitis) and to six adults with human immunodeficiency virus infection using a Respirgard II nebuliser. Technetium-99m labeled colloidal human serum albumin was used as an indirect marker for pentamidine and deposition in the lungs was detected by a gamma camera. RESULTS: Absolute deposition of pentamidine was not related to age, height, weight, spirometry, or ventilation characteristics. Deposition, as a mean (SD) percentage of nebuliser output, was similar in children aged 8-11 years (5.5(2.4)%), teenagers aged 12-15 years (7.2(2.2)%) and adults (7.1(2.6)%). Aerosol concentration within the lungs (% nebuliser output deposited/predicted total lung capacity) was therefore higher in children (1.9(1.5)%/1) and teenagers (1.9(0.7)%/1) than in adults (1.0(0.7%)/1), and was negatively correlated with height (r = -0.69) and weight (r = -0.50). Deposition of aerosol in the region of the large central airways was particularly marked in children. Small reductions in forced expiratory volume in one second and forced vital capacity after treatment did not differ significantly between adults and children and visual analogue scores of subjective adverse effects did not vary with age. CONCLUSIONS: These results suggest that children probably require lower nebuliser pentamidine doses to produce lung pentamidine concentrations equivalent to those found to be effective for preventing P carinii pneumonia in adults using the Respirgard II nebuliser.
Psoralen and Coumarin Photochemistry in HSA Complexes and DMPC Vesicles†

Abstract The photochemistry and photophysics of several psoralens and coumarins have been examined in human serum albumin (HSA) complexes and dimyristoylphosphatidylcholine (DMPC) vesicles. Fluorescence spectroscopy indicates that there are multiple binding sites with polarities that are intermediate between those of acetonitrile and water for the substrates complexed to HSA. In the case of the 6,7-dimethoxycoumarin-HSA complex, laser flash photolysis experiments provide evidence for the formation of radical cation in addition to triplet. Radical cations are not detected for other coumarin-HSA complexes, either due to a lower yield of formation or to rapid reaction of an initial radical cation with adjacent amino acids. Fluorescence spectra for coumarins indicate that they are primarily solubilized in the polar headgroup region in DMPC vesicles. Consistent with this, radical cations generated by photoionization are detected in transient experiments. For dimethoxycoumarins the radical cation is long-lived, indicating rapid exit from the vesicle and decay in the aqueous phase. However, 4,5′,8-trimethylpsoralen and 7-ethoxy-4-hexadecylcoumarin radical cations are much shorter-lived, presumably due to rapid decay by electron recombination in the vesicle. The results for both HSA complexes and vesicles indicate that radical ions may play a role in psoralen and coumarin photochemistry in a cellular environment.
When too many are not enough: Human resource slack and performance at the Dutch East India Company (1700–1795)

Slack is an elusive concept in organizational research, with studies documenting a variety of relationships between slack and firm performance. We advocate treating slack not as a resource, but as a practice – a sequence of events and responses over time. A longitudinal analysis of the Dutch East India Company (1700–1795) highlights the use of slack as a response to a resource constraint (the shortage of skilled labor). After documenting the negative performance effects of skill shortage, we identify a trade-off in the use of human resource slack (number of sailors above what is operationally required), in which slack enhanced operational reliability, but reduced efficiency. Derived from a historical context, this trade-off has contemporary relevance and is helpful in reconciling contradictory evidence on slack.
Initiating Inhaled Steroid Treatment for Children With Asthma in the Emergency Room: Current Reported Prescribing Rates and Frequently Cited Barriers

Objective The objective of this study was to determine how frequently emergency department (ED) physicians prescribe inhaled corticosteroids (ICSs) and describe commonly cited barriers. Methods We surveyed members of the American Academy of Pediatrics Section on Emergency Medicine between May and August 2011. Demographic data were collected. Using the knowledge-attitude-behavior model for barriers to physician guideline adherence, we asked 20 Likert scale questions regarding barriers to ICS prescribing. Our primary outcome was reported frequency of ICS prescribing. We defined frequent prescribers as those who prescribe ICS more than 25% of the time. Logistic regression models were built for each barrier category and identified barriers that predict infrequent prescribing. Results Two hundred seven (19.5%) of the 1062 surveyed responded; 75.8% report prescribing ICS 25% of the time or less. For knowledge, those who agreed that the National Heart, Lung, and Blood Institute guidelines are not clear regarding the ED physician’s role were less likely to be frequent prescribers compared with those who disagreed (adjusted odds ratio [OR], 0.31; 95% confidence interval [CI], 0.11–0.90). For attitude, those who agreed it is not the role of the ED physician to prescribe long-term medications were less likely to be frequent prescribers (adjusted OR, 0.12; 95% CI, 0.04–0.37). For behavior, those who agreed they do not routinely start long-term medications because they cannot see patients in follow-up were less likely to be frequent prescribers (adjusted OR, 0.21; 95% CI, 0.07–0.58). Conclusions Emergency department physicians report low rates of ICS prescribing. Commonly cited barriers include unclear guidelines, believing that long-term medication prescribing is not within their role, and inability to see patients in follow-up. Addressing guideline discrepancies may improve preventive care delivery in the ED.
An outdoor-to-indoor propagation scenario at 28 GHz

The outdoor to indoor propagation of microwave frequency at 28 GHz is investigated. The indoor location is an empty standard open landscape office and the outdoor unit is placed on the roof of a neighboring building 70 m from the office. The chosen scenario gives the possibility to measure path loss through both standard window glass and coated glass, known for its high transmission loss also at lower radio frequencies. The excess loss due to transmission through walls is presented together with the results of a long-term measurement.
Promoting fruit and vegetable consumption among students: a randomized controlled trial based on social cognitive theory.

OBJECTIVE To assess the effectiveness of an educational intervention based on social cognitive theory on increasing consumption of fruit and vegetable among Grade 4 students. METHODS The randomised study was conducted in Isfahan, Iran, during 2011 and comprised 138 students, who were randomly divided into intervention and control groups. Data was collected at the beginning and three months after the intervention. A self-administered questionnaire based on constructs of social cognitive theory and food consumption was used. Theory-based nutrition education was imparted on the intervention group. Data was analysed using SPSS 15 and appropriate statistical tests. RESULTS The intervention group had 68 (49.27%) subjects, while there were 70 (50.72%) controls. After the intervention, mean scores of behavioural capability (p < 0.001), self-efficacy in difficult situations (p = 0.04), self-efficacy in selecting fruits and vegetables (p = 0.01), social support (p = 0.03), and observational learning (p = 0.002) had significantly improved in the intervention group. Nutritional behaviour also showed significant improvement on mean daily intake of fruits and vegetables in the intervention group (p < 0.001). CONCLUSION Intervention based on social cognitive theory led to increase in the consumption of fruits and vegetables among students, which confirmed the efficiency of social cognitive theory for such interventions.
Bacteriuria and colonization of double-pigtail ureteral stents: long-term experience with 237 patients.

We prospectively studied 266 patients with indwelling double-pigtail ureteral stents to determine the incidence of stent colonization and associated bacteriuria. A urine culture was obtained just prior to stent insertion and was repeated at the time of its removal. The stent itself was also cultured. Of the 237 evaluable patients, 71 (29.9%) developed bacteriuria. Of the 237 stents, 161 (67.9%) became colonized with microorganisms. Pseudomonas aeruginosa was the most common pathogen isolated from the urine and the stents. Stents in female patients had a higher rate of colonization than those used in males (74.4% v 66.5%). The longer the duration of stenting, the higher was the rate of colonization (58.6% for stents left for < 1 month v 75.1% for those left for > 3 months). The rate of colonization according to catheter type was as follows: C-flex 55.5%, silicone 62.6%, urethane 100%, and Urosoft 56%. Long-term ureteric stenting is associated with a high rate of bacteriuria and stent colonization. The duration of stenting and the type of stent influence the results. We recommend that patients with double-J ureteral stents who could be at risk from bacteremia be covered by appropriate antibiotics, and the stents should be kept indwelling for the shortest possible time. If a patient with a stent develops symptomatic infection, an antibiotic should be started that covers the Pseudomonas species.
Hospital ownership, decisions on supervisory board characteristics, and financial performance.

BACKGROUND Dynamic and complex transformations in the hospital market increase the relevance of good corporate governance. However, hospital performance and the characteristics of supervisory boards differ depending on ownership. The question therefore arises whether hospital owners can influence performance by addressing supervisory board characteristics. PURPOSE The objective of this study is to explain differences in the financial performance of hospitals with regard to ownership by studying the size and composition of supervisory boards. METHODOLOGY The AMADEUS database was used to collect information on hospital financial performance in 2009 and 2010. Business and quality reports, hospital websites, and data from health insurer were used to obtain information on hospital and board characteristics. The resulting sample consisted of 175 German hospital corporations. We utilized ANOVA and regression analysis to test a mediation hypothesis that investigated whether decisions regarding board size and composition were associated with financial performance and could explain performance differences. FINDINGS Financial performance and board size and composition depend on ownership. An increase in board size and greater politician participation were negatively associated with all five tested measures of financial performance. Furthermore, an increase in physician participation was positively associated with one dimension of financial performance, whereas one negative relationship was identified for nurse and economist participation. For clerics, no associations were found. PRACTICE IMPLICATIONS Decisions concerning board size and composition are important as they relate to hospital financial performance. We contribute to existing research by showing that, in addition to board size and physician participation, the participation of other professionals can also influence financial performance.
Excitatory amino acid concentrations in ventricular cerebrospinal fluid after severe traumatic brain injury in infants and children: the role of child abuse.

BACKGROUND Excitotoxicity is an important mechanism in secondary neuronal injury after traumatic brain injury (TBI). Excitatory amino acids (EAAs) are increased in cerebrospinal fluid (CSF) in adults after TBI; however, studies in pediatric head trauma are lacking. We hypothesized that CSF glutamate, aspartate, and glycine would be increased after TBI in children and that these increases would be associated with age, child abuse, poor outcome, and cerebral ischemia. METHODS EAAs were measured in 66 CSF samples from 18 children after severe TBI. Control samples were obtained from 19 children who received lumbar punctures to rule out meningitis. RESULTS Peak and mean CSF glycine and peak CSF glutamate levels were increased versus control values. Subgroups of patients with TBI were compared by using univariate regression analysis. Massive increases in CSF glutamate were found in children <4 years old and in child abuse victims. Increased CSF glutamate and glycine were associated with poor outcome. A trend toward an association between high glutamate concentration and ischemic blood flow was observed. CONCLUSIONS CSF EAAs are increased in infants and children with severe TBI. Young age and child abuse were associated with extremely high CSF glutamate concentrations after TBI. A possible role for excitotoxicity after pediatric TBI is supported.
Electrohydrodynamic thrust density using positive corona-induced ionic winds for in-atmosphere propulsion

Previous work has characterized electrohydrodynamic (EHD) thruster performance, determining that thrust-to-power ratios are comparable with that of conventional propulsion at the laboratory scale. Achievable thrust density of EHD propulsion has yet to be experimentally quantified and could be a limiting factor in its application. In this paper, we quantify the achievable thrust density for a wire-to-cylinder electrode geometry using positive corona discharges for electrode pairs operating in parallel and in series. Geometric parameters, including the non-dimensional inter-pair and stage spacings, are varied, and the effect on current and thrust is measured. We estimate a maximum thrust per unit area of 3.3 N m−2 and a maximum thrust per unit volume of 15 N m−3, which we compare with the characteristic thrust density of a range of aircraft. We find that trade-offs exist between thrust density and the achieved thrust-to-power ratio, where increases in the former through either increased power input or pair packing density lead to decreases in the latter. We conclude that EHD propulsion has the potential to be viable from both an energy efficiency perspective (our previous study) and a thrust density perspective (this paper), with the greatest likelihood of viability for smaller aircraft such as unmanned aerial vehicles.
DNA damage, DNA susceptibility to oxidation and glutathione level in women with polycystic ovary syndrome

Recent studies have addressed the possibility of an association between polycystic ovaries and ovarian cancer. DNA damage is the first step of the carcinogenesis, and susceptibility to cancer, in general, is characterized by high DNA damage. Free radical‐mediated DNA damage and impaired antioxidant defence have been implicated as contributory factors for the development of cancer. This study evaluates DNA damage (strand breakage, base oxidation, formamidopyrimidine DNA glycosylase (Fpg) sensitive sites), H2O2‐induced DNA damage, a marker of DNA susceptibility to oxidation and glutathione (GSH) level, a powerful antioxidant, in women with polycystic ovary syndrome (PCOS). Women with PCOS showed a significant decrease in GSH level, a significant increase in DNA strand breakage and H2O2‐induced DNA damage. Although Fpg‐sensitive sites were higher in the PCOS group compared to the control group, the difference did not reach a statistically significant level. Significant correlations were found between free testosterone and DNA strand breakage (r = 0.46, p<0.01) and free testosterone and H2O2‐induced DNA damage (r = 0.41, p<0.05). The data indicate that DNA damage and susceptibility of DNA to oxidative stress are increased in women with PCOS and may explain the association between PCOS and ovarian cancer.
Chromium-Induced Genotoxicity and Interference in Human Lymphoblastoid Cell (TK6) Repair Processes

Two model chromium (Cr) compounds, one hexavalent (sodium chromate) and one trivalent (chromium chloride), were investigated in a human lymphoblastoid cell line (TK6) to increase our knowledge regarding Cr-induced genotoxicity mechanisms. Both selected compounds were genotoxic using the comet assay, although the percentage of DNA in tail obtained after treatment with CrVI was significantly higher than that obtained with CrIII, at the higher concentrations tested. To determine the nature of the induced damage, enzymes recognizing oxidized bases were used. Treatments with formamidopyrimidine (FPG) and endonuclease III (EndoIII) displayed a greater degree of DNA damage, indicating that the induction of oxidized bases accounts for an important proportion of the damage induced by Cr compounds. In addition, the kinetic repair studies showed that generated DNA damage is removed in approximately 8 h, with the damage induced by CrIII being removed/repaired more rapidly than damage produced by CrVI. To detect Cr interferences with the repair process, a post-treatment was applied after exposure to 2 Gy gamma radiation. Post-treatment significantly delayed the repair kinetics of DNA damage induced by radiation. This interference effect induced by CrVI was more pronounced. In conclusion, evidence indicates that a high proportion of the Cr-induced DNA damage is correlated with oxidative damage, and that both Cr compounds interfere with repair mechanisms involved in repair of DNA damage induced by gamma radiation.
Involvement of the CACNA1A gene containing region on 19p13 in migraine with and without aura

Objective: To assess the involvement of the 19p13 familial hemiplegic migraine (FHM) locus in migraine with and without aura. Background: Migraine with and without aura are likely to be polygenetic multifactorial disorders. FHM is a rare dominantly inherited type of migraine with aura. In about 50% of families, FHM is caused by mutations in the P/Q-type calcium channel α1A-subunit (CACNA1A) gene on chromosome 19p13. The CACNA1A gene is thus a good candidate gene for “nonhemiplegic” migraine with or without aura. Methods: The authors performed an affected sibpair analysis using flanking and CACNA1A intragenic markers. The authors assessed the occurrence of shared parental marker alleles among 189 affected siblings from 36 extended families with typical migraine with or without aura. Results: Sibling pairs with any form of migraine had inherited the same 19p13 CACNA1A-containing region significantly more frequently than expected by chance (maximum multipoint lod score = 1.22). This result was almost exclusively dependent on the increased sharing found in sibling pairs with migraine with aura (maximum multipoint lod score = 1.41). The locus-specific relative risk for a sibling (λs) to suffer from migraine with aura, defined as the increase in risk of the trait attributable to the 19p13 locus, was λs = 1.56. When combining migraine with and without aura, λs was 1.22. Conclusions: The increased allele sharing in the CACNA1A gene region on 19p13 is consistent with an important involvement of this region in migraine, especially migraine with aura.
