Title : Sleep Bruxism in Children with and without Anxiety

Study Objectives: Sleep bruxism (SB) is common in children and is associated with somatic symptoms and sleep disturbance. Etiological theories posit the role of anxiety, suggesting youth with anxiety disorders may be at high-risk for SB, but empirical data are lacking. Furthermore, parent report rather than polysomnography (PSG) has been used to examine SB-anxiety relationships in children. We examined rates of PSG-detected compared to parent-reported SB in children with generalized anxiety disorder (GAD) and healthy controls. Associations among SB, somatic complaints, and sleep disturbance were also examined. Methods: Thirty-one children, aged 7-11 years, completed one night of PSG monitoring and 7 daily reports of somatic symptoms. Bruxism events were scored during rapid eye movement (REM) sleep and non-REM sleep stages 1 and 2. Results: Almost one-third of children showed evidence of SB based on PSG. No associations were identified between parent-reported and PSG-detected SB. Rates of SB did not differ between anxious and control groups, though children with GAD showed more tonic bruxisms during REM sleep. Presence of SB predicted more muscle aches and stomach aches, and children with SB had more awake time after sleep onset than non-bruxers. Conclusions: Results indicate poor concordance between PSG-detected and parent-reported SB in children, suggesting that parent report alone is not a reliable method for detection. The lack of association between SB and anxiety status suggests that stress sensitivity rather than anxiety per se, may be predictive of SB. Associations between SB, somatic symptoms, and sleep disturbance are congruent with the broader literature.
The Effects of Simulated Spermophilus Franklinii Burrowing on Prairie Soil Invertebrate Communities

Burrowing of subterranean mammals can have ecological effects on overlying vegetation, invertebrate communities, and surrounding soil characteristics. Franklin’s ground squirrel (Spermophilus franklinii) is a declining, tunneling mammal species previously found throughout Central Illinois. Preference for natural tallgrass prairie habitat with loose soil marks Illinois as the southern extreme of their range. Through urbanization and agricultural practices this species’ population numbers have declined dramatically in southern and central Illinois. This study looks at the effects simulated Franklin’s ground squirrel burrows have on soil invertebrate composition, abundance, and diversity by comparing effects of the presence/exclusion of burrows, animals, and their interactions. Through experimental plot manipulation we discovered that simulated burrowing has limited effects on soil invertebrate abundance. However, it’s most pronounced effects were found at the entrance of the burrow where abundances were 33% to 50% lower than all other sampling locations. Interactive effects of burrow and animal also had an effect on Homoptera and Coleoptera abundance, only when burrow and animal were present simultaneously. The independent presence of an animal was also shown to have an overall effect on soil invertebrate diversity. Future research is recommended to look at the effects of simulated burrowing on plant community composition as well as soil characteristics and attempt to unite all three factors.
Relationship of physical activity and weight loss in women with Class II and Class III obesity: Mediation of exercise-induced changes in tension and depression

Exercise is a predictor of both weight loss and mood improvement. Because of the minimal energy expenditure associated with exercise in obese persons due to their poor cardiovascular fitness, it has been suggested that exercise-induced mood change may mediate the relationship of exercise with weight loss for them. In the current experimental study, women with Class II and III obesity (N = 75) participated in a 24-week moderate exercise and nutrition education program at southeastern U.S. Young Men's Christian Association (YMCA) centers. As expected, exercise session attendance was significantly associated with weight loss (β=-.47), but directly accounted for only an estimated 17% of the loss in weight. Using the Baron and Kenny approach, significant partial mediation was found for changes over 24 weeks in both tension and depression scores. This suggested that exercise indirectly affected weight change through psychological pathways, and supported tenets of social cognitive theory. After replications and extensions, findings may help to improve explanatory theory and weight management
Design and modeling of an additive manufactured thin shell for x-ray astronomy

Future X-ray astronomy missions require light-weight thin shells to provide large collecting areas within the weight limits of launch vehicles, whilst still delivering angular resolutions close to that of Chandra (0.5 arc seconds). Additive manufacturing (AM), also known as 3D printing, is a well-established technology with the ability to construct or ‘print’ intricate support structures, which can be both integral and light-weight, and is therefore a candidate technique for producing shells for space-based X-ray telescopes. The work described here is a feasibility study into this technology for precision X-ray optics for astronomy and has been sponsored by the UK Space Agency’s National Space Technology Programme. The goal of the project is to use a series of test samples to trial different materials and processes with the aim of developing a viable path for the production of an X-ray reflecting prototype for astronomical applications. The initial design of an AM prototype X-ray shell is presented with ray-trace modelling and analysis of the X-ray performance. The polishing process may cause print-through from the light-weight support structure on to the reflecting surface. Investigations in to the effect of the print-through on the X-ray performance of the shell are also presented.
The Trouble with Drink: Intoxication, (In)Capacity and the Evaporation of Consent to Sex

Feminists have analysed the problematic way in which rape law has evolved in the shadow of the mind/body dualism. This paper will extend this analysis to the problems arising when consent to sex is “intoxicated consent”. One central question is the whether consent is a state of mind or a set of actions or behaviours, performed in certain way, to signify consent. Whether one believes consent to be a state of mind or an action, adding intoxication to the mix renders the problem yet more intractable for criminal law. If consent is a state of mind then being in an intoxicated state can make it extremely difficult to come to a settled state of mind about consent since intoxicants clearly affect the cognitive capacities and it is often also of course, difficult for others to ascertain one’s state of mind. However if consent is an action, alcohol/drugs again can impair the physical and verbal abilities to the extent that action is either impossible or, again, difficult to read. Either way intoxication can render consent obscure. This paper offers a feminist critique of the criminal law’s treatment of the parameters of consent when the person giving consent is intoxicated.
Kuwait Stock Market Participants’ Perceptions of Information Useful to the Investment Decisions

This paper reports the results of an investigation into Kuwaiti multi-investors’ perceptions of the different types of information useful for investment decision-making. One hundred and sixty-eight useable questionnaires out of 410 with a response rate of 41% were collected. The questionnaire targeted key players in the Kuwaiti stock market—namely, analysts, fund managers, individual investors and stockbrokers who are involved with investment decisions. The study found that the most important sources of information to the Kuwaiti multi-investors concerned “general corporate information was information about major types of product (services), and for “financial information,” was operating profit. In addition, the most important item in “non-financial information” was new contracts won by the company. Furthermore, the most important item in “corporate governance information” was corporate strategies. Moreover, the most important item in “corporate social information” was improvement in customer services. Finally, the most important item in “type of valuation methods” was fundamental analysis. However, with the exception of some corporate information items, no significant differences were found between participants’ perceptions. It can be inferred that all the related corporate information sources useful for investment decision-making used in this study are important to the all Kuwaiti stock exchange participants.
Genetic and Molecular Aspects of Plant Response to Drought in Annual Crop Species

Stress is defined as any soil and climatic conditions or combination of both that hinders the full realization of genetic potential of a plant, limiting their growth, development and reproduction. These effects in plants of agricultural interest have a major impact on productivity and quality and thus represent, together with biotic stress, the cause of the gap between yield potential and actual production (Ciais et al., 2005). Stressful environmental conditions are extreme air temperature, drought, excessive presence of salts, anoxia and hypoxia, ozone and heavy metals. Among these factors, heavy damages on agricultural production in Mediterranean environments are exerted by drought, salt stress and early spring low temperatures. The changes in climate forecasted for the near future are expected to exacerbate the onset and magnitude of events of stress due to increased drought and erratic rainfall and rise of evapotranspiration rates due to growing temperatures.

Integrating TAM and TPB with Perceived Risk to Measure Customers’ Acceptance of Internet Banking

This article proposes a revised technology acceptance model to measure customers ‘acceptance of internet banking, in Iran. This study uses the technology acceptance model, theory of planned behavior and theory of perceived risk to build a comprehensive model. We designed a questionnaire and used it to survey a randomly selected sample of customers of internet banking, and In June 2010, a sample of 349 customers of national bank of Iran completed the questionnaire. We analyzed the data using structuralalequation modeling (SEM) to evaluate the strength of the hypothesized relationships, if any, among the constructs. The results provide support of the proposed model and confirm its robustness in predicting customers’ intention to accept internet banking and imply that the perceived usefulness is the most important positive predictor and security risk is the most important negative predictor of the intention to use internet banking.
Soil organic matter alterations by short-term composted coffee pulp waste : evidence from pyrolysis-field ionisation mass spectrometry Zusammenfassung

This study investigates the impact of compost from coffee pulp waste on the composition of soil organic matter (SOM) under controlled laboratory conditions. Compost samples were collected after the thermophilic, mesophilic and the final phase and an equivalent of 48 t ha-1 was added to samples of a tropical Nitisol. The soil-compost-mixtures were incubated aerobically for 14 weeks. At the end of incubation the Corg concentrations and the total ion intensities of pyrolysis-field ionization mass spectrometry (Py-FIMS) were larger in compost treatments than in the control. Despite of similar initial organic Corg and Nt contents among compost amended treatments, less organic C was mineralized following the application of compost from the thermophilic than from later composting phases. The SOM in the soil that received the “thermophilic” compost contained significantly higher proportions of carbohydrates, heterocyclic/nitrilic N-compounds, peptides, sterols and n-fatty acids than the other amended soils. Temperature-resolved volatilization curves for carbohydrates, N-compounds and peptides showed that the enriched compounds covered a wide range of thermal stability. In conclusion, the compost from the thermophilic phase had the best effect in terms of biologically labile C sequestration and stabilization of native organic C in a clay-rich tropical Nitisol. If confirmed for other composts and soils, this may have also considerable economic implications because the time period of composting can be shortened.
QUANTITATIVE TRADING OF GOLD AND SILVER USING NONLINEAR MODELS

The main aim of this paper is to forecast gold and silver daily returns with advanced regression analysis using various linear and non-linear models. ARMA models are used as a linear benchmark for comparison purposes with non-linear models such as Nearest Neighbours, MultiLayer Perceptron (MLP) and Higher Order Neural Networks (HONN). The models are assessed using statistical criteria such as correct directional change as well as financial criteria such as risk adjusted return. The main aim is to find which of these models generate the best returns and if nonlinear models can be used for generating excess returns in the precious metals market. This is achieved by implementing a trading simulation where the forecast is translated into a trading signal. Profit statistics are calculated taking into account transaction costs. It is concluded that, for the January 2000-May 2006 period under review, nonlinear models like MLPs and HONNs did outperform the linear ARMA models. In the end, the performance of both MLP and HONN models showed the presence of nonlinearities in the gold and silver prices as it was found that nonlinear models can be effectively used for generating excess returns in these markets.
Processing of 13C-labelled phytoplankton in a fine-grained sandy-shelf sediment (North Sea): relative importance of different macrofauna species

On-board and in situ experiments with 13 C-labelled diatoms were carried out to investigate the processing of algal carbon by the macrofauna community of a fine sandy-shelf site in the southern German Bight (North Sea). The time series (12, 30, 32 and 132 h incubations) was supplemented by additional laboratory experiments on the role of the dominant macrofauna organism, the bivalve Fabulina fabula (Bivalvia: Tellinidae), for particulate organic matter subduction to deeper sediment layers. The specific uptake of algal 13 C by macrofauna organisms was visible after 12 h and constantly increased during the incubation periods. F. fabula, a facultative (surface) deposit- and suspension-feeder, Lanice conchilega (Polychaeta: Terebellidae), a suspension-feeder and the (surface) deposit-feeder Echinocardium cordatum (Echinodermata: Spatangidae) were responsible for the majority of macrofaunal carbon processing. Predatory macrofauna organisms like Nephtys spp. (Polychaeta: Nephtyidae) also quickly became labelled. The rapid subduction of fresh organic matter by F. fabula down to ca. 4 to 7 cm sediment depth could be demonstrated, and it is suggested that entrainment by macrofauna in this fine-grained sand is much more efficient than advective transport.
On locating local earthquakes at the Messina Strait network

A computer program (HYPOSTRE) has been elaborated to determine the hypocentral parameters of local earthquakes, even when they are recorded by a small number of stations. These are the most frequent conditions prevailing around the Strait of Messina. The program employs the first arrivals of P and S waves, a model of local crust consisting of four plane and parallel layers, and an algorithm based on that of Geiger. HYPOSTRE can determine simultaneously the four unknowns X, cp, h and H (HYPOSTRE 4) and can calculate the epicentral coordinate separately from focal depth (HYPOSTRE 2). In both cases the program follows an iterative process. In particular, HYPOSTRE 2 shows convergence towards a final solution, through a series of « damped » approximations. The application of HYPOSTRE to about twenty earthquakes, which have occured in the Strait of Messina and in the Gulf of Patti, demonstrates a good convergence and a general stability of results. Finally, comparison with analogous determinations — carried out by other programs, with different crustal models and using a greater number of recorded data — confirms the reliability of HYPOSTRE.
Maternal and fetal outcome of Placenta Previa at a tertiary centre in North Kerala, India

Placenta previa is defined as placenta that is implanted somewhere in the lower uterine segment either over or very near the internal cervical os. It occurs in 2.8/1000 singleton pregnancies and 3.9/1000 twin pregnancies. The incidence of hysterectomy after caesarean section (CS) for placenta previa is 5.3% (relative risk compared with those undergoing CS without placenta previa in 33). Perinatal mortality rates are three or four times higher than in normal pregnancies. The classification of placenta previa includes
A phosphotransacetylase from uropathogenic Staphylococcus saprophyticus: Characterization, kinetic analysis and its allosteric inhibition by a-ketoglutarate

Objectives: The genome of Staphylococcus saprophyticus, an uropathogen, contains SSP2124 gene encoding a putative phosphotransacetylase (Pta). Pta plays significant role in energy metabolism as well as colonization of uropathogens. In this study, cloning, expression, characterization and kinetic analysis of S. saprophyticus Pta have been undertaken. Methods: The SSP2124 gene was amplified by PCR from the genome of S. saprophyticus and subcloned into pET28a(+) vector and expressed in E. coli BL21. The recombinant Pta was affinity purified by Ni-NTA column. Its characterization as well as its steady-state kinetic analysis has been studied by standard procedures. Results: The recombinant Pta forms dimers as determined by gel filtration. The activity of the enzyme was maximal at a temperature range of 30-35 o C and at the pH range of 7.5-8.5. It was greatly stimulated by K + and NH 4 + ions, but inhibited by Na + ion. Kinetic analysis and product inhibition studies suggest that there is a kinetic mechanism that proceeds through random addition of both substrates to the enzyme before any product is released. The enzyme was inhibited in both acetyl-CoA-forming (forward) and acetyl phosphate-forming (reverse) directions by adenosine triphosphate (ATP) and α-ketoglutarate but not affected by pyruvate and reduced nicotinamide adenine dinucleotide. ATP was competitive with respect to CoA and noncompetitive with respect to acetyl phosphate. The inhibition by a-ketoglutarate, on the other hand, was allosteric with halfsaturations at 6.5 ± 0.7 mM and Hill coefficients of 2.6 ± 0.8 and 3.3 ± 0.2, in forward and reverse directions, respectively. Conclusions: S. saprophyticus Pta belongs to the Pta I family and show similar biochemical features as well as kinetic mechanism with other members. And the most importantly, this study presents the first example of allosteric regulation of a member of class I Ptas. The authors do not have a conflict of interest.
Stress and Learning in the Higher School Certificate.

The paper reports the results of a study conducted in one Sydney (Australia) comprehensive high school. Sixty-seven Year 12 and 62 Year 11 students completed a questionnaire package measuring stress responses, goals, and academic self-efficacy. Findings show that 31% of the Year 12 and 25% of the Year 11 students reported symptoms of anxiety, depression, or both, which fell outside the normal range. More females than males reported the symptoms. The goals that students held for the Higher School Certificate were found to be predominately performance rather than mastery oriented. Performance-avoidance goals were significantly and positively correlated with stress responses. Self-efficacy was significantly and positively correlated with mastery. (Contains 15 references.) (JDM) Reproductions supplied by EDRS are the best that can be made from the original document. The University of Sydney STRESS AND LEARNING IN THE HIGHER SCHOOL CERTIFICATE Lorraine Smith Faculty of Nursing, University of Sydney Kenneth E. Sinclair Faculty of Education, University of Sydney Completion of the New South Wales Higher School Certificate is generally perceived as a stressful undertaking but there has been little research devoted to the nature of the stress responses experienced by students, or to its relationship with students' goals, academic selfefficacy or performance. This study reports the results of a study conducted in one Sydney comprehensive high school. Sixty-seven Year 12 and sixty-two Year 11 students completed a questionnaire package measuring stress responses, goals and academic self-efficacy. A small focus discussion group was also conducted for each year group. Results show 31% of Year 12 and 25% of Year 11 students are reporting symptoms of anxiety, depression and/or stress which fall outside the normal range. Significantly more females than males report these symptoms. The goals that students hold for the HSC were found to be predominantly performance rather than mastery oriented. Whilst mastery was salient for Year 11 students this dropped away markedly in Year 12 as the demands for performance increased. Performance-avoidance goals were significantly and positively correlated with stress responses. Self-efficacy was significantly and positively correlated with mastery.
The effects of high school choices on academic performance and early labour market outcomes

Using microdata on the 1995 cohort of Italian high school graduates, this paper studies the relationship between the type of high school attended (general versus technical; private versus public) and indicators of subsequent performance. Simultaneity issues that potentially bias this type of exercise are tackled by instrumental variables. Results indicate that choices greatly depend upon the family of origin and prior school performance. General high schools are found to increase the probability of transition to university and to improve performance once at university. On the other hand, private high schools appear to be associated with lower academic performance. Technical schools improve the quality of the school-to-work transition, both in terms of employment probabilities and earnings. Considering interactions between university and labour market participation decisions reduces the estimated direct impact of general high schools, while leaving the effects of private schools unaltered.
