Assessment of appropriate medication- use by 2015 Beers criteria among elderly critically ill patients in Jordan.

Background: Inappropriate prescribing can cause significant morbidity and mortality in geriatric patients. Studies implementing the updated 2015 American Geriatrics Society (ACG) Beers Criteria in the identification of potentially inappropriate medications (PIM) are lacking. In addition, there is limited information regarding PIM use in critically ill older adults. Objective: To investigate the prevalence, patterns and determinants of PIM among elderly critically ill patients in Jordan. Setting: critical care unit (surgical, medical, cardiac) at Jordan University Hospital, Amman, Jordan Method: A cross-sectional study conducted over a 5- month period. Patients 65 years and older, taking at least one medication and admitted to critical care unit, were included. PIM were identified and classified in accordance with the American Geriatrics Society 2015 Beers Criteria. Results: One hundred and fifty-four patients were included (55.8% males), the mean age was 75.4 ± 7.1 years. The median number of prescribed medications was 11 (IQR=6). The use of at least one PIM was identified in 51 (33.1%). In 90 cases (58.4%), medications to be used with caution in older adults were also evaluated. Patients who received at least one PIM were prescribed a higher total number of medications in the hospital (13 vs. 11.5, P<0.05). Diabetes was also significantly associated with PIM prescription (84.3% vs. 49.5%, P<0.005). Conclusion: PIM prevalence among ICU elderly patients was high (every third patient). The factors associated with PIM prescription included the total number of medications and presence of diabetes mellitus
The Effects of Cultural Intelligence and Transformational Leadership Style of Managers on Employee Resistance to Change

One of the most important challenges faced by organizations is the environmental factors’ change and increasing global competitions. In response to this challenge, it should be noted that change management is a difficult task. Most of organizational changes fail. Lack of personnel’s agreement with the change and their resistance are among the most important factors that cause the failure of organizational change. The objective of this study was to evaluate the effect of two factors of cultural intelligence of managers and transformational leadership style on employees' resistance to change. The population of this research includes managers and employees of Jam Petrochemical Company (Iran). The sample consisted of 260 employees and 60 managers of various units of the company. Data were collected using the tool of questionnaire. To analyze the data SMART PLS structural equation modeling software was used. The findings of this study show that cultural intelligence of managers both directly and through transformational leadership style has a positive and significant impact on the resistance to change and also the transformational leadership style has a positive and significant impact on the resistance to change.

Forest Fragment and Breeding Habitat Characteristics Explain Frog Diversity and Abundance in Singapore

Habitat loss and fragmentation can have severe negative and irreversible effects on biodiversity. We investigated the effects of forest fragmentation on frog diversity in Singapore because of its high rates of deforestation and the demonstration that frogs are some of the most sensitive species to habitat degradation. We surveyed frog species in 12 forest fragments varying from 11 to 935 ha. We compared differences in species richness, abundance, and Shannon's index in relation to forest fragment size, connectivity (distance between fragments), and breeding habitat heterogeneity. A total of 20 species from 12 genera and five families were encountered in 12 fragments. Larger fragments and those closer to larger fragments had higher species richness. Abundance, however, was not correlated with forest area or connectivity, but we found fewer individual frogs in the larger fragments. We also found that breeding habitat heterogeneity best explained frog species diversity and abundance in forest fragments. Fragments with a high diversity of breeding habitats had more species. We found no evidence to suggest that abundance and diversity are strongly correlated, particularly in disturbed areas, but that breeding habitat heterogeneity is an under‐appreciated factor that should be considered when prioritizing areas for anuran conservation. Enriching breeding habitat heterogeneity, creating corridors between fragments, and reforesting degraded areas are some of the most beneficial strategies for preserving urban frog biodiversity.

TheSensitive Period forMale-to-Female SexReversal Begins at the Embryonic Stage in the Nile Tilapia and is Associated With the Sexual Genotype

In this study, we sought to determine the mechanism of early sex reversal in a teleost by applying 4 hr feminization treatments to XY (17a-ethynylestradiol 2000mg L ) and YY (6500mg L ) Nile tilapia embryos on the first day post-fertilization (dpf). We then searched for changes in the expression profiles of some sex-differentiating genes in the brain (cyp19a1b, foxl2, and amh) and in sex steroids (testosterone, 17b-estradiol, and 11-ketotestosterone) concentrations during embryogenesis and gonad differentiation. No sex reversal was observed in YY individuals, whereas sexreversal rates in XY progeny ranged from 0 60%. These results, together with the clearance profile of 17a-ethynylestradiol, confirmed the existence of an early sensitive period for sex determination that encompasses embryonic and larval development and is active prior to any sign of gonad differentiation. Estrogen treatment induced elevated expression of cyp19a1b and higher testosterone and 17b-estradiol concentrations at 4 dpf in both XY and YY individuals. foxl2 and amhwere repressed at 4 dpf and their expression levels were not different between treated and control groups at 14 dpf, suggesting that foxl2 did not control cyp19a1b in the brains of tilapia embryos. Increased cyp19a1bexpression in treated embryos could reflect early brain sexualization, although this difference alone cannot account for the observed sex reversal as the treatment was ineffective in YY individuals. The differential sensitivity of XY and YY genotypes to embryonic induced-feminization suggests that a sex determinant on the sex chromosomes, such as a Y repressor or an X activator, may influence sex reversal during the first steps of tilapia embryogenesis.
But a walking shadow: designing, performing and learning on the virtual stage

For hundreds of years, the remediation of reality has been built into all technologies of representation. Although taken as a whole, the available information enables a qualitative assessment of the history of multimedia and their influences on different fields of knowledge, there are still some areas that require more focused research attention. For example, the relationship between media evolution and new developments in scenographic practice is currently under investigation. This article explores the issue of immediacy as a condition of modern theatre in the context of digital reality. It discusses the opportunities and challenges that recent technologies present to contemporary practitioners and theatre design educators, creating a lot of scope to break with conventions. Here, we present two case studies that look into technology‐mediated learning about scenography through the employment of novel computer visualization techniques. The first case study is concerned with new ways of researching and learning about theatre through creative exploration of design artefacts. The second case study investigates the role of the immersive virtual world Second Life in effective teaching of scenography, and in creating and experiencing theatrical performances.

A View into a Decade of Arts Integration.

The John F. Kennedy Center for the Performing Arts has been involved in an intensive, sustained partnership with schools, Changing Education Through the Arts (CETA), since 1999. The CETA program is a whole school reform model designed to impact student learning and attitudes by building teachers’ capacities to make arts integration one of their primary approaches to teaching across the curriculum. During its first decade (1999 to 2009), the program formally examined its impact through three independent, multi-year evaluation studies. Examined together, the three studies shed light on a decade of arts integration outcomes for students, teachers, and schools. Findings are reported in four areas—the CETA program design, and the program’s impact on students, teachers, and schools. Findings for the program design include: the structure of the CETA program’s professional learning model was integral to its success in schools and the most critical factor for improving practice; and the importance of opportunities for arts coaching in the classroom and participation in study groups as ongoing program supports. Findings for the impact on students include: increased student engagement, both socially and academically; a moderately high positive relationship between student engagement and the extent of teachers’ professional development; growth in students’ cognitive and social skills; and gains in standardized test scores for lower performing students. Findings for the impact on teachers include: development of strong support for the value of arts integration for reaching all kinds of learners, widening the opportunity for all students to be successful, and providing multiple ways for students to express knowledge and understanding; teachers’ increased use of collaborative learning strategies with students; change in the role arts specialists play in schools; and time as a critical factor for effective implementation. Findings for the impact on schools include: changes in school culture, including increased teacher collaboration resulting in a more positive and cohesive, and child-centered environment; growth of the school as a learning community; and the importance of administrative support and leadership.
Drug and Alcohol Dependence

Background: Few studies have investigated physiological stress (re)activity in relation to substance use, especially in adolescents. Using substances is one way to stimulate physiological arousal, therefore inherent hypo-arousal may be associated with substance use in adolescents. The purpose of this study was to examine the relation of autonomic nervous system (ANS) activity with alcohol and tobacco use in adolescents. Methods: ANS activity and perceived stress during a social stress procedure were examined in relation to substance use. 275 Dutch adolescents from a general population study provided complete data. Heart rate was recorded continuously during a pre-task rest period, a stressful task period and a post-task recovery period. Alcohol and tobacco use were self-reported. Results: Adolescents who consumed a medium and high number of alcoholic drinks per week (more than two) exhibited lower heart rates during the entire stress procedure as compared to those who consumed a low number of alcoholic drinks. Adolescents who smoked every day portrayed blunted heart rate reactivity to stress as compared to adolescents who smoked less frequently or not at all. Perceived stress was not related to alcohol or tobacco use. Conclusions: Overall lower heart rate in adolescents who drank more and blunted heart rate reactivity to stress in those who used tobacco every day may indicate inherent hypo-arousal of the ANS system in those vulnerable to use substances more often. These adolescents may actively seek out substances in order to achieve a more normalized state of arousal. © 2012 Elsevier Ireland Ltd.
Acute Stress Influences Neural Circuits of Reward Processing

People often make decisions under aversive conditions such as acute stress. Yet, less is known about the process in which acute stress can influence decision-making. A growing body of research has established that reward-related information associated with the outcomes of decisions exerts a powerful influence over the choices people make and that an extensive network of brain regions, prominently featuring the striatum, is involved in the processing of this reward-related information. Thus, an important step in research on the nature of acute stress’ influence over decision-making is to examine how it may modulate responses to rewards and punishments within reward processing neural circuitry. In the current experiment, we employed a simple reward processing paradigm – where participants received monetary rewards and punishments – known to evoke robust striatal responses. Immediately prior to performing each of two task runs, participants were exposed to acute stress (i.e., cold pressor) or a no stress control procedure in a between-subjects fashion. No stress group participants exhibited a pattern of activity within the dorsal striatum and orbitofrontal cortex (OFC) consistent with past research on outcome processing – specifically, differential responses for monetary rewards over punishments. In contrast, acute stress group participants’ dorsal striatum and OFC demonstrated decreased sensitivity to monetary outcomes and a lack of differential activity. These findings provide insight into how neural circuits may process rewards and punishments associated with simple decisions under acutely stressful conditions.
Tradeoff Theory and Leverage Dynamics of High-Frequency Debt Issuers

We examine debt dynamics of high-frequency public industrial debt issuers, who raised the bulk of all US public and private corporate debts over the past three decades. Contrary to dynamic tradeoff theory, the cross-sectional leverage-profitability correlation is non-positive at recapitalization points. Moreover, the speed-of-adjustment to target leverage deviations is no higher than for low-frequency debt issuers. Accounting for investment finance, high-frequency issuers finance large investment shocks with new debt - even when overleveraged - and delever in periods with low investment financing needs. We interpret this deleveraging as maintenance of future debt-issue capacity.
The X-ray luminosity-temperature relation of a complete sample of low-mass galaxy clusters

We present Chandra observations of 23 galaxy groups and low-mass galaxy clusters at 0.03 < z < 0.15 with a median temperature of ${\sim }2{{\rm keV}}$. The sample is a statistically complete flux-limited subset of the 400 deg^2 survey. We investigated the scaling relation between X-ray luminosity (L) and temperature (T), taking selection biases fully into account. The logarithmic slope of the bolometric L–T relation was found to be 3.29 ± 0.33, consistent with values typically found for samples of more massive clusters. In combination with other recent studies of the L–T relation, we show that there is no evidence for the slope, normalization, or scatter of the L–T relation of galaxy groups being different than that of massive clusters. The exception to this is that in the special case of the most relaxed systems, the slope of the core-excised L–T relation appears to steepen from the self-similar value found for massive clusters to a steeper slope for the lower mass sample studied here. Thanks to our rigorous treatment of selection biases, these measurements provide a robust reference against which to compare predictions of models of the impact of feedback on the X-ray properties of galaxy groups.
Reaction relations in the granite system : Implications for trachytic and syenitic magmas

In order to evaluate crystallization paths offeldspathic, silica-poor rocks such as trachytes and syenites characterized by high-temperature crystallization histories (as indicated by the paucity of hydrous minerals, the presence of ternary feldspar, and the occasional presence of high-temperature minerals such as pyroxene and olivine), a detailed theoretical investigation of the sodic region of the synthetic granite system, Ab-Or-An-Qz-(HrO), was undertaken. Calculated phase relations in the feldspar system (i.e., the system Ab-Or-An(HrO) and in the synthetic granite system were used to identify and investigate the regions of complete and incomplete resorption of plagioclase (and less importantly, alkali feldspar) as a function of pressure, activity of HrO, and silica content. The regions of complete and incomplete resorption of feldspar contract markedly with increasing HrO and with increasing silica; they shift to higher An contents with increasing pressure. At low HrO contents, however, the resorptional regime can be entered even when the melt is silica-saturated. Trachytic and syenitic magmas are likely to enter a region ofat least incomplete resorption of plagioclase at an early stage of their crystallization history. However, it is possible that these magmas could re-enter a coprecipitation region once the activity of water and of other melt components has increased sufficiently during crystallization. This type of crystallization history could also characterize magmas more siliceous than trachytes as long as the bulk An and Or contents were low and the albitic region could be reached while the HrO content was still low.
When Does Cash Matter? Evidence for Private Firms

Using a database of more than 180,000 private companies from 2000 to 2009, we find that the benefits of holding more cash vary substantially with a firm’s size and the conditions it faces. Cash holdings matter most for small firms: when there are negative shocks to industry or macroeconomic conditions, a small firm’s cash holdings are positively associated with changes in its sales and assets. Cash is less important for other conditions. Differences in the benefits of cash holdings between large and small firms are traced to a firm’s ability – and willingness – to increase leverage when there is a cash shortfall.
Disentangling the dark matter halo from the stellar halo

The outer haloes of the Milky Way (MW) and Andromeda (M31) galaxies contain as much important information on their assembly and formation history as the properties of the discs resident in their centres. Whereas the structure of dark matter (DM) haloes has been studied for a long time, new observations of faint structures hiding in the depths of the stellar halo have opened up the question of how the stellar halo is related to the DM underlying it. In this paper, we have used the Constrained Local UniversE Simulation (CLUES) project to disentangle the stellar and DM components of three galaxies that resemble the MW, M31 and M33 using both DM-only simulations and DM + gas-dynamical ones. We find that stars accreted in substructures and then stripped follow a completely different radial distribution than the stripped DM: the stellar halo is much more centrally concentrated than DM. In order to understand how the same physical process – tidal stripping – can lead to different z= 0 radial profiles, we examined the potential at accretion of each stripped particle. We found that star particles sit at systematically higher potentials than DM, making them harder to strip. We then searched for a threshold in the potential of accreted particles φth, above which DM particles in a DM-only simulation behave as star particles in the gas-dynamical one. We found that in order to reproduce the radial distribution of star particles, one must choose DM particles whose potential at accretion is ≳16φsubhalo, where φsubhalo is the potential at a subhaloes edge at the time of accretion. A rule as simple as selecting particles according to their potential at accretion is able to reproduce the effect that the complicated physics of star formation has on the stellar distribution. This result is universal for the three haloes studied here and reproduces the stellar halo to an accuracy of within ∼2 per cent. Studies which make use of DM particles as a proxy for stars will undoubtedly miscalculate their proper radial distribution and structure unless particles are selected according to their potential at accretion. Furthermore, we have examined the time it takes to strip a given star or DM particle after accretion. We find that, owing to their higher binding energies, stars take longer to be stripped than DM. The stripped DM halo is thus considerably older than the stripped stellar halo.
Dotyophycus pacifi cum I. A. Abbott (Liagoraceae, Rhodophyta) a new record for the Atlantic Ocean

Specimens of Dotyophycus pacificum I. A. Abbott were found during a survey of Rhodophyta on the coast of Bahia state. The samples were taken from 23-36 meters depth and the specimens found were studied in detail and compared to other morphologically similar species. This is the first time that the genus Dotyophycus is cited for the Atlantic Ocean.
