The Sustainability of Community of Practice： The Case of English as a Foreign Language Teachers at Taif University, Saudi Arabia

This paper reports on a qualitative study that is a follow-up to the research undertaken on CoP in my Ph.D. study. The study, which was conducted at Taif University, Saudi Arabia, aimed to enhance the instructional practices of eight male English as a foreign language (EFL) teachers about corrective feedback. In one of its phases, the study investigated the implementation of Community of Practice (CoP) as a form of professional development (PD) for Taif University EFL teachers. However, the Ph.D. study did not investigate the sustainability of CoP due to the limited time frame of the study. Therefore, in the current study the researcher interviewed the eight EFL male teachers 18 months after the original Ph.D. study was conducted. The current study has investigated the sustainability and the continuation of CoP after the researcher had left. The results showed that the teachers conducted only one CoP meeting after the researcher’s departure and that some promises made by the teachers had not been achieved, such as the creation of an electronic CoP. Furthermore, the teachers reported some difficulties that hindered the continuation of the CoP and thus led to its dissolution at that time. The results of the current study have provided some suggestions about how CoP as a form of PD could be sustained in such a context. Recommendations are made for both policy makers and EFL teachers at Taif University.

We study the gravitational collapse of pre-stellar sources and the associated evolution of their chemical composition. We use the University of Grenoble Alpes Astrochemical Network (UGAN), which includes reactions involving the different nuclear-spin states of H2, H + 3 , and of the hydrides of carbon, nitrogen, oxygen, and sulphur, for reactions involving up to seven protons. In addition, species-to-species rate coefficients are provided for the ortho/para interconversion of the H3 + H2 system and isotopic variants. The composition of the medium is followed from an initial steady state through the early phase of isothermal gravitational collapse. Both the freeze-out of the molecules on to grains and the coagulation of the grains were incorporated in the model. The predicted abundances and column densities of the spin isomers of ammonia and its deuterated forms are compared with those measured recently towards the pre-stellar cores H-MM1, L16293E, and Barnard B1. We find that gas-phase processes alone account satisfactorily for the observations, without recourse to grain-surface reactions. In particular, our model reproduces both the isotopologue abundance ratios and the ortho:para ratios of NH2D and NHD2 within observational uncertainties. More accurate observations are necessary to distinguish between full scrambling processes – as assumed in our gas-phase network – and direct nucleusor atom-exchange reactions.
Government Spending and the Taylor Principle Gisle

This paper explores how government size a¤ects the scope for equilibrium indeterminacy in a New Keynesian economy where part of the population live hand-to-mouth. I nd that in this framework, a larger public sector may widen the scope for self-ful lling prophecies to occur. This takes place even though taxes serve to reduce swings in current income. In general, government provision of goods that are Edgeworth substitutes for private consumption tend to narrow the scope for indeterminacy, while government goods that are Edgeworth complements for private consumption increase the problem of indeterminacy. Hence monetary policy should be conducted with an eye to the amount and composition of government consumption.

The protective effect of omega-3 fatty acids on cardiac injury in lipopolysaccharide-induced acute sepsis rats model

Sepsis is a systemic inflammatory response to a local infection induced by microbes and endotoxins. Severe sepsis can lead to vital organ dysfunction and corresponds with a high mortality. Despite intensive treatment modalities, such as antibiotics, low molecular weight heparin therapy, and so on, there is still no highly effective therapeutic approach for sepsis. Recently, the combination of antibiotics with drug molecules has attracted attention. The search for new potentially potent medicines and the elucidation of the underlying mechanisms of sepsis pathology are vital for the advancement of sepsis therapy. A lipopolysaccharide (LPS)-induced sepsis rat model was established, the cardiac muscle tissues were stained with Hematoxylin & Eosin (HE), and the changes in cardiac tissue morphology were examined under a transmission electron microscope. The protein expression levels of protein phosphokinase I (PIIC), the inner mitochondrial membrane protein (ANT), and phospholamban (PLN) were analyzed by Western blot. Next, the mRNA expression levels of calsequestrin (CASQ1), Na+-Ca2+ exchanger (NCX), sarcoplasmic reticulum Ca2+ATPase (SERCA2a), ryanodine receptor (RyR2), protein phosphatase type 1α (PPP1CA), mitochondrial carrier, adenine nucleotide translocator 25, member 4 (Slc25a4), and PLN were all analyzed using real-time quantitative PCR. We found a lesion in the mitochondria of the lipopolysaccharide (LPS)-induced sepsis model. After treatment with omega-3 fish oil, the cardiac muscle cell morphology was recovered and the ultrastructural lesions were alleviated. Furthermore, we identified the involvement of genes expressed in cardiac muscle cell plasma, as well as mitochondria related enzymes, among the beneficial effects of fish oil treatment on sepsis. In conclusion, Omega-3 fish oil alleviates mitochondria lesions in our lipopolysaccharide-induced sepsis rat model. This work provides a potential molecular mechanism underlying sepsis treatment with fish oil fatty acids, indicating its possible application in sepsis therapy.
Indirect Compensation Technique for Low-Voltage CMOS Op-amps

Two and three-stage indirect-compensated op-amps employing split-length composite devices are presented. By incorporating split-length devices the right-half plane zero which hampers op-amp performance can be eliminated. Chip test results indicate significant enhancements in op-amp speed while reducing power consumption and layout area. Moreover, these techniques can be used to compensate three-stage op-amps operating at low supply voltage (VDD).
Clinical Study Device-Training for Individuals with Thoracic and Lumbar Spinal Cord Injury Using a Powered Exoskeleton for Technically Assisted Mobility : Achievements and User Satisfaction

Objective. Results of a device-training for nonambulatory individuals with thoracic and lumbar spinal cord injury (SCI) using a powered exoskeleton for technically assisted mobility with regard to the achieved level of control of the system after training, user satisfaction, and effects on quality of life (QoL). Methods. Observational single centre study with a 4-week to 5-week intensive inpatient device-training using a powered exoskeleton (ReWalk ). Results. All 7 individuals with SCI who commenced the devicetraining completed the course of training and achieved basic competences to use the system, that is, the ability to stand up, sit down, keep balance while standing, and walk indoors, at least with a close contact guard. User satisfaction with the system and device-training was documented for several aspects.The quality of life evaluation (SF-12v2 ) indicated that the use of the powered exoskeleton can have positive effects on the perception of individuals with SCI regarding what they can achieve physically. Few adverse events were observed: minor skin lesions and irritations were observed; no falls occurred. Conclusions. The device-training for individuals with thoracic and lumbar SCI was effective and safe. All trained individuals achieved technically assisted mobility with the exoskeleton while still needing a close contact guard.
Scour around the Circular and Square Profile

The study shows the methodology and results of the conducted local erosion research around circular and square profile piers under clear-water conditions. Physical and numerical modelling technique has been used to achieve the primary goal for determining the depth of the erosion pit, comparing with the results obtained through the application of empirical equations suggested by a series of authors. The shape of the pier cross section (circular and square), number of piers in the flow cross section (1, 2, 3) and the flow depth with the corresponding velocity were varied. The granulation of the applied model sediment is uniform and homogeneous (d=2mm). Basic geometrical features of the physical and numerical model were not changed (except for the piers). Based on physical model measurements and numerical model simulations, maximum erosion depths (scour) were determined. The obtained results were compared mutually and with empirical equation results using the same geometric and hydraulic conditions. Numerical simulations were conducted with the aim of Mike 21fm numerical model based on the finite volume method. The modelling results indicate a more pronounced erosion around the circular piers. The empirical equation of Melville (1997) gives the values of erosion pit depth closest to the measurement results of the physical model and the results of numerical model simulations. The highest degree of resemblance with the models results was achieved in the case where three piers were embedded. The measurement results of the physical model are more consistent with the results of the empirical equation compared to the results obtained by numerical simulations.
Population size and status of Common Raven ( Corvus corax ) on the central-western islands of the Canarian archipelago

During the 2009 breeding season (February-June) we studied the population size of Common Raven on four islands of the Canarian archipelago. A total of 44 pairs were censused: ten in Gran Canaria, 12 in Tenerife, 17 in La Palma and five in La Gomera. Most of these pairs have their territories in ravines, gullies and sea cliffs, coinciding with or close to areas where livestock is still being raised (herds of goats and sheep) or presence of feral goats. The size of the floating population is unlikely to exceed that of the breeding birds. We also discuss real and potential threats.

Clinical Study Joint Assessment of Intended and Unintended Effects of Medications : An Example Using Vascular Endothelial Growth Factor Inhibitors for Neovascular Age-RelatedMacular Degeneration

Objective. To estimate the net health benefits of pegaptanib and ranibizumab by considering the impact of visual acuity and unintended effects (cardiovascular and hemorrhagic events) on quality-of-life among persons with neovascular age-related macular degeneration. Methods. We designed a probabilistic decision-analytic model using published data. It employed 17 visual health states and three for unintended effects. We calculated incremental net health benefits by subtracting the harms of each medication from the benefit using the quality-adjusted life year (QALY). Results. In a hypothetical cohort of 1,000 75-year olds with new-onset bilateral age-related macular degeneration followed for ten years, the mean QALYs per patient is 3.7 for usual care, 4.2 for pegaptanib, and 4.3 for ranibizumab. Net benefits decline with increasing baseline rates of unintended effects. Interpretation. Net health benefits present a quantitative, potentially useful tool to assist patients and ophthalmologists in balancing the benefits and harms of interventions for age-related macular degeneration.
PERFORMANCE OF THE CERN LOW ENERGY ION RING ( LEIR ) WITH XENON BEAMS

In 2017 the CERN Low Energy Ion Ring demonstrated once more the feasibility of injecting, accumulating, cooling and accelerating a new nuclei, 129Xe39+. The operation of this new ion species started at the beginning of March with the start up of the xenon ion source and the Linac3. Ten weeks later the beam arrived to the Low Energy Ion Ring (LEIR) triggering the start of several weeks of beam commissioning in view of providing the injector complex with xenon beams for different experiments and a series of machine development experiments in LEIR. Two types of beams were setup, the so called EARLY beam, with a single injection into LEIR from Linac3, and the NOMINAL beam with up to seven injections. 2017 was as well an interesting year for LEIR because several improvements in the control system of the accelerator and in the beam instrumentation were done in view of increasing the machine reliability. This paper summarises the beam commissioning phase and all the improvements carried out during 2017.
Comparative analysis of fatty acids profiles in muscle and liver of Tunisian thick lipped grey mullet Chelon labrosus reared in seawater and freshwater

This study was conducted to determine differences between thick lipped grey mullet Chelon labrosus reared in seawater (SW) and freshwater (FW) in terms of proximate composition and fatty acid composition. The Juveniles of seawater originating C. labrosus were acclimated to freshwater in same conditions as their counterparts in Seawater. Decrease in salinity led to higher moisture and lipid content and lower protein content (P < 0.05) in muscle, but had not marked impacts on moisture and led to higher lipid content of liver . Dominant fatty acids in both SWand FW-reared fish were C14:0 (myristic acid), C16:0 (palmitic acid), C18:0 (stearic acid), C18:1n 9 (oleic acid), C18:2n 6 (linoleic acid), C20:4n-6 (Arachidonic acid), C18:3n-3 (alpha-linolenic acid), C20:5n-3 (eicosapentaenoic acid) , C22:6n 3 (docosahexaenoic acid). The lipids of SW-reared fish contained significantly (P< 0.05) higher level of saturated and monounsaturated fatty acids. However FW fish contained a higher level of n-3 polyunsaturated fatty acids (PUFA), particularly docosahexaenoic acids (DHA) and eicosapentaenoic acids (EPA). Considering the overall nutritional quality indices (n-3/ n-6, FLQ, AI and TI), the muscle of C labrosus reared in freshwater were good sources of n-3 PUFAs particularly EPA and DHA.
Title Sources of Funds and Investment Strategies of Venture Capital Funds : Evidence from Germany , Israel , Japan and the UK

Using a newly constructed data set, we compare sources of funds and investment strategies of venture capital (VC) funds in Germany, Israel, Japan and the UK. Sources of VC funds differ significantly across countries, e.g. banks are particularly important in Germany, corporations in Israel, insurance companies in Japan, and pension funds in the UK. VC investment patterns also differ across countries in terms of the stage and sector of financed companies, as well as in the geographical focus of investments, and these differences are significantly related to the variations in funding sources. However, the influence of particular classes of institutions differs across countries. For example, bank backed VC firms in Germany and Japan are as involved in early stage finance as other funds in these countries, whereas in Israel and the UK they tend to invest in relatively late stage finance. While these financial institutional factors account for some of the differences in investment patterns across countries, other considerations (such as supply of entrepreneurs) are of greater significance.

This paper develops a framework for the quantitative analysis of individual income dynamics, mobility and welfare. Individual income is assumed to follow a stochastic process with two (unobserved) components, an i.i. d. component representing measurement error or transitory income shocks and an AR(1) component representing persistent changes in income. We use a tractable consumption-saving model with labor income risk and incomplete markets to relate income dynamics to consumption and welfare, and derive analytical expressions for income mobility and welfare as a function of the various parameters of the underlying income process. The empirical application of our framework using data on individual incomes from Mexico provides striking results. Much of measured income mobility is driven by measurement error or transitory income shocks and therefore (almost) welfare-neutral. A smaller part of measured income mobility is due to either welfare-reducing income risk or welfare-enhancing catching-up of lowincome individuals with high-income individuals, both of which have economically significant effects on social welfare. Decomposing mobility into its fundamental components is thus seen to be crucial from the standpoint of welfare evaluation. ∗We are grateful to seminar participants at Columbia, Harvard and Pennsylvania State University for many useful comments. Particular thanks to Francois Bourguignon, Francisco Ferreira, Gary Fields, and the other participants at the World Bank/Universitat Autonoma de Barcelona Workshop on Mobility for very helpful discussions. Our appreciation to Edwin Goni and Mauricio Sarrias for inspired research assistance.

Self-Objectification Among Physically Active Women 1

Objectification Theory (Fredrickson & Roberts, 1997) was used to examine (a) the mediation effects of body shame and flow on the relationship between self-objectification and disordered eating, (b) age differences in self-objectification, body shame, flow, and disordered eating, (c) the prediction of physical activity from self-objectification, flow, body shame, and disordered eating, and (d) the relationships between self-objectification, flow, and physical activity. Participants were 394 women ages 18–64. Results revealed that (a) body shame mediated the relationship between self-objectification and disordered eating, (b) younger women reported higher levels of self-objectification, body shame, dieting, and several flow characteristics, (c) older women scored higher on the loss of self-consciousness subscale of the flow measure, and (d) self-objectification was a significant predictor of physical activity.
Post-Trauma c Stress Disorder and Acute Stress Disorders and Death Anxiety

Between the state of Israel independent declaration in 1948, until this very days, wars, military operations and on-going national terror had been its daily routine to cope with. Th e main goal of this study was to review published studies on the impact of those extreme negative life events on the well-being and mental health of various groups of Arab and Jewish civilians in Israel. In addition, this study emphasizes well-known PTSD risk factors related to terrorism, military operations and war in Israel, as well as dissociative symptoms, ASD symptoms, and Death anxiety. Th e study also deals with some of the background characteristics, the internal and the external resources of the individual, in three age groups, which can take the role of mediator variables between those negative events and the populations’ well-being. Th e literature published in Israel from the beginning of studding those subjects, available up to January 2017, was systematically reviewed. About thirteen studies on the impact of on-going terror attacks and risk factors for distress, trauma and PTSD and, about ten studies on coping strategies were identifi ed. Causes, risk factors, variety of outcomes and coping strategies were widespread from the earlier and traditional to more recent and modern approaches towards those subjects and sometimes integrated.
Analgesic Activity of the Kappa Opioid Receptor Agonist RU-1205 in Rats

Introduction: Opioid analgesics are the most efficient and widely used drugs for the management of moderate to severe pain. However, side effects associated with mu receptor activation, such as respiratory depression, tolerance and physical dependence severely limit their clinical application. Currently, the kappa-opioid system is the most attractive in terms of the clinical problem of pain, because kappa-agonists do not cause euphoria and physical dependence. The purpose of this study was to evaluate the antinociceptive effect of the novel compound - RU-1205. Methods: The analgesic activity of RU-1205 was studied on nociceptive models that characterize the central and peripheral pathways of pain sensitivity (hot plate test, electrically induced vocalisation, formalin test, writhing test). Results: RU-1205 exhibited highly potent antinociceptive effects in rodent models of acute pain with ED50 values of 0.002 - 0.49 mg /kg. Pretreatment with the κ-opioid receptor antagonist norBinaltorphimine significantly attenuated the analgesic activity of investigated substance in a hot plate test. Conclusions: It was established that the compound shows a significant dose-dependent central and peripheral analgesic effect. It was assumed kappa-opioidergic mechanism of analgesic effect of RU-1205.
GENDER DIFFERENCES IN ENTREPRENEURIAL ACTIVITY : AN ANALYSIS OF INFORMAL INSTITUTIONAL FACTORS

The aim of this paper is to determine and compare the influence of certain informal institutional factors upon the decision to become an entrepreneur among men and women entrepreneurs in Spain. To attain this objective we adopt a socio-cultural institutional approach. We undertake a logit model using a robust Spanish dataset from 2003. The main contribution of this paper lies on the identification of specific factors that influence women entrepreneurship, which differ from those of men’s. The results show the importance of entrepreneurial self-confidence, as a common factor for both women and men entrepreneurial activity. The main result indicates that the presence of entrepreneurial role models is an important informal institutional factor explaining the difference between women and men’s entrepreneurial activity.
