Effects of Lyman-alpha scattering in the IGM on clustering statistics of Lyman-alpha emitters

We investigate the correlations between the observed fraction of Lyα emission from star-forming galaxies and the large scale structure by post-processing snapshots of a large, high resolution hydrodynamical simulation with a Lyα radiative transfer code at redshifts z = 4, 3, 2. We find correlations of the observed fraction with density, density gradient along the line of sight, velocity and velocity gradient along the line of sight, all within the same order of magnitude (tens of percent). Additionally, a correlation with the angular momentum of the dark matter halo is detected. In contrast to a previous study, we find no significant deformation of the 2-point correlation function due to selection effects from radiative transfer in the IGM within the limited statistics of the simulation volume.
Simulation of the spatiotemporal aspects of land erodibility in the northeast Lake Eyre Basin, Australia, 1980–2006

This paper explores spatiotemporal patterns in land erodibility in the northeast portion of the Lake Eyre Basin, Australia, using the Australian Land Erodibility Model (AUSLEM) in simulations from 1980 to 2006. First, spatial patterns in land erodibility are examined. We then present an analysis of seasonal and interannual variations in land erodibility. Patterns in land erodibility change are compared to rainfall variability, the El Nino–Southern Oscillation (ENSO) and Pacific (inter-) Decadal Oscillation (PDO). Land erodibility is found to peak in the study area between early spring (September, October, November) and late summer (January, February, March), and reach a minimum over winter (June, July, August). Weak correlations are found between modeled land erodibility, rainfall, ENSO, and the PDO. The results indicate a complex landscape response to climate variability, with land erodibility dynamics being affected by antecedent rainfall and vegetation conditions which generate lag responses in land erodibility change. The research highlights the importance of developing methods for monitoring conditions driving variations in wind erosion at the landscape scale to enhance land management policy in arid and semiarid landscapes at a time of uncertain future climate changes.
Co-composting of coconut coir pith with solid poultry manure

Coir pith, a ligno-cellulosic biomass formed during extraction of coir fibre from coconut husk, accumu-lates as a waste material near coir processing factories causing environmental and disposal problems. The feasibility of co-composting coir pith with solid poul-try manure was tested with and without lime and rock phosphate amendment. The results revealed that the composting process facilitated by poultry manure amendment brought about bioconversion of coir pith to a final product in 45 days and the final product possessed physico-chemical characteristics required for quality organic manure. C: N ratio, which is con-sidered as a maturity index of composting process, reduced during the composting process, to 21.42. The results of plant test using cowpea as bioassay plant revealed that the compost reached adequate maturity from biological point of view for use as an organic input in crop production. Keywords:

An infinite class of periodic solutions of periodically perturbed Duffing equations at resonance

In this paper, by using a generalized form of the PoincareBirkhoff Theorem, we demonstrate that the Duffing equation d2 + g(x) = p(t) (= p(t + 27r)) may also admit an infinite number of 27r-periodic solutions even in a resonance case. 1. In this paper we study the existence problem of periodic solutions for the Duffing equation (1.1) dt2 + g(x) = p(t) where g(x), p(t) E C(R, R) and p(t) is 2Xr-periodic. In the super-linear case, that is, lim [x-lg(x)] = oo, jxj-> oo it has been proved in a recent paper by W. Y. Ding that (1.1) has infinitely many 2ir-periodic solutions [1]. D. E. Leach proved the existence and uniqueness of 27r-periodic solution of (1.1) under the following Loud condition (1.2) m2 0 and two such constants X and ,t [2]. R. Reissig proved the existence of periodic solutions of (1.1) under a weaker condition [3] m 2 a > 0. The crucial point of the conditions above is to exclude the resonance cases. At resonance, (1.1) may have no bounded solution [6]; therefore, the existence problem of periodic solutions challenges attention. A. C. Lazer and D. E. Leach, and L. Cesari succeeded to prove the existence of 2ir-periodic solutions of (1.1) at a point of resonance provided that h(x) = g(x) m2x is bounded and some other additional conditions are assumed [4, 5]. In a recent paper, the present author resolved the existence problem of 2ir-periodic solutions of (1.1) under a weakened version of (1.2) [6]: m2 < g'(x) < (m + 1)2 (g(0) 0).

The role of geography in the success of the balearic tourism industry

A really large tourist destination, such as the Balearic Islands cannot be defined as a single geographic space without regional differentiation; it spans several islands within each of which are a multiplicity of coastal areas with very varied geographical morphology and differing degrees of exploitation for tourism. We aim to conduct a statistical analysis of the standard features of such coastal areas to determine the geographic base common to the entire Balearic archipelago as a mass tourist destination. Our analysis is based on the different theoretical concepts of a destination as they appear in tourist literature: A geographically defined area, a group consumption brand name, a location defined by a concrete offer, and so on, and the industrial district concept as initially proposed by Marshall and later developed by authors, such as Krugman and Becattini. We set out to conduct a fundamentally quantitative analysis for which purpose we established a database containing 41 categories of geographical, commercial and business data for each of the 82 Balearic tourist areas. This information is integrated into a statistically homogenous set of values that enables the application of the Agglomerative Hierarchical Clustering (AHC) statistical method. The results obtained show that the islands of Menorca and Formentera constitute minor products in clear contrast with the major destinations of Mallorca and Ibiza. The latter two have developed a model composed of a pattern of large areas that are virtually indistinguishable from each other. Each zone can accommodate almost every kind of tourist wishing to visit the Balearic Islands, regardless of nationality, family status or economic level. A final result indicates that the large local hoteliers have developed a very special trading model: Targeting a specific niche of tourist demand while offering a wide geographical distribution of their establishments.
COMPARATIVE STUDY BETWEEN GRANISETRON, ONDANSETRON AND PROPOFOL FOR THE PREVENTION OF EMESIS AFTER GYNAECOLOGICAL LAPROSCOPY

Objective: The aim of this work was to evaluate the efficiency and safety of granisetron versus ondansetron and Propofol for prevention of postoperative nausea and vomiting in patient undergoing day case gynaecological laproscopy under general anaesthesia. Material and Methods: This study was conducted in Alquwayiyah General Hospital and Riyadh Medical Complex. K.S. A, over and period of six months, from January 2004 to June 2004 (both Months inclusive). 120 adult non pregnant female patients (18-40 yrs of age) of ASA I-II scheduled for diagnostic gynaecological laproscopy were included in this study. Patients with severe systemic or endocrine disease who had predisposing factors for delayed gastric emptying, such as diabetes, cholecystitis or neuromuscular disorders were excluded. Results: This study was conducted in 120 patients classified into six groups (20 patients each). The first group received granisetron, the second group ondansetron, the third, fourth and fifth group received propofol in different does. The last group received normal saline as placebo ( control group). Treatment with either granisetron (group-I) and ondansetron (group-II) resulted in significant lower incidence of nausea and vomiting over 12 hours observation postoperatively compared with other group. However granisetron resulted in significant in lower incidence than ondansteron. Conclusion: It is concluded that preoperative prophylactic administration of intravenous granisetron 40 ug/kg is effective and superior to ondansetron and propofol in preventing nausea and vomiting after gynaecological laproscopic surgical procedures.
Golden Rule of Forecasting: Be Conservative

This paper proposes a unifying theory of forecasting in the form of a Golden Rule of Forecasting. The Golden Rule is to be conservative. A conservative forecast is consistent with cumulative knowledge about the present and the past. To be conservative, forecasters must seek all knowledge relevant to the problem, and use methods that have been validated for the situation. A checklist of 28 guidelines is provided to implement the Golden Rule. This article’s review of research found 150 experimental comparisons; all supported the guidelines. The average error reduction from following a single guideline (compared to common practice) was 28 percent. The Golden Rule Checklist helps forecasters to forecast more accurately, especially when the situation is uncertain and complex, and when bias is likely. Non-experts who know the Golden Rule can identify dubious forecasts quickly and inexpensively. To date, ignorance of research findings, bias, sophisticated statistical procedures, and the proliferation of big data have led forecasters to violate the Golden Rule. As a result, despite major advances in forecasting methods, evidence that forecasting practice has improved over the past half-century is lacking.
How coaches establish trust in team sports? : a qualitative research on coaching leadership

Havia Tuire, 2017. How coaches establish trust in team sports? A qualitative research on coaching leadership. Master’s Thesis in Sport and Exercise Psychology. Faculty of Sport and Health Sciences. University of Jyväskylä. 70p. There has been a significant amount of research dedicated to understanding the interpersonal relationships in sports from various viewpoints. The current literature identifies the concept of trust and knowing the individuals within team crucial in coaching context. However, there is very limited research on how to foster trust in teams in elite level coaching context, especially in Finland topic is poorly covered. Hence, this study aimed to describe the coaching philosophies and the specific methods used to establish trust in coach-athlete relationship and within team environment of four coaches (1 female, 3 male) in elite level sports in Finland (floorball=1, football=1, ice hockey=1 and ringette=1). The data was collected using a semi-structured interview as the data collection method. Coaching experience of participants ranged from 20 to 45 years. An interpretative thematic analysis with both inductive and deductive reasoning was utilized in the analysis of the data. The data was transcribed and further coded through Atlas.ti software, (version 7.1). The results revealed a comprehensive picture of the factors that describe trust in the whole sport team and the organisation, and which can be linked together under an umbrella of trustful environment. The coaches agreed that the true core of trust is captured in every day coaching actions by supporting individuals, on and off the field, and getting to know them as individuals, as well as involving them in different ways and encouraging them to see mistakes as a part of learning process. In conclusion, this study provided new information regarding practical methods and principles about how to establish trust in coach-athlete relationship and within teams. The findings may be beneficial in coaching education, in teams and on a broader perspective also within individual level of sports. The findings support similar previous research and thus speaks to the worthy pursuit of establishing trust in teams which in turn may benefit not only individual wellbeing and motivation but also team performance outcomes.
Selection bias in dynamically measured supermassive black hole samples: its consequences and the quest for the most fundamental relation

We compare the set of local galaxies having dynamically measured black holes with a large, unbiased sample of galaxies extracted from the Sloan Digital Sky Survey. We confirm earlier work showing that the majority of black hole hosts have significantly higher velocity dispersions ? than local galaxies of similar stellar mass. We use Monte Carlo simulations to illustrate the effect on black hole scaling relations if this bias arises from the requirement that the black hole sphere of influence must be resolved to measure black hole masses with spatially resolved kinematics. We find that this selection effect artificially increases the normalization of the Mbh–? relation by a factor of at least ? 3; the bias for the Mbh–Mstar relation is even larger. Our Monte Carlo simulations and analysis of the residuals from scaling relations both indicate that ? is more fundamental than Mstar or effective radius. In particular, the Mbh–Mstar relation is mostly a consequence of the Mbh–? and ? –Mstar relations, and is heavily biased by up to a factor of 50 at small masses. This helps resolve the discrepancy between dynamically based black hole–galaxy scaling relations versus those of active galaxies. Our simulations also disfavour broad distributions of black hole masses at fixed ? Correcting for this bias suggests that the calibration factor used to estimate black hole masses in active galaxies should be reduced to values of fvir ? 1. Black hole mass densities should also be proportionally smaller, perhaps implying significantly higher radiative efficiencies/black hole spins. Reducing black hole masses also reduces the gravitational wave signal expected from black hole mergers.
Changes in the Educational Achievement of Immigrant Youth in Western Societies: The Contextual Effects of National (Educational) Policies

Prior research has identified a large number of factors that explain differences in scholastic achievement. However, analyses of the educational performance of students from immigrant families and possible changes in these performances over time remain quite scarce. The present article addresses this shortcoming by means of a multilevel analysis of 24 Western countries based on PISA data from 2000 to 2012. Since the relevance of individual explanatory factors and school characteristics has been repeatedly shown, we focus on structural effects at the level of national policies. Our results show that the disparities in educational success between native and immigrant youth declined between 2000 and 2012 in several countries under study, especially in Central Europe. Nevertheless, there still are marked and relatively stable differences between various types of immigrant societies (e.g. traditional immigration countries like Canada vs. Continental European Countries like Germany). Analysing macro-level factors we observe stability as well as change: On the one hand, the positive effect of the quality of the educational system for immigrant students’ educational achievement remains stable. On the other hand, negative effects of the stratification of the educational system diminished, while educational expenditures gained influence over the last decade.
The effect of pacing frequency on the amplitude and time-course of cardiomyocyte shortening in isolated rat cardiomyocytes

Introduction. Isolated adult cardiomyocytes are an important research tool in the field of pathophysiology of the cardiac muscle. Isolated myocytes are electrically paced to elicit their contractile function. In the majority of cases, the pacing frequency used in in vitro experiments is 1 Hz, while physiological heart rate in rodent heart (the most common source of isolated cardiomyocyte) is about six times higher (approx. 6 Hz). Aim. To compare the amplitude and kinetics of contractile signal in myocytes paced at 1 Hz (the most often used frequency of pacing in vitro) with these parameters measured in cardiomyocytes paced at frequency closer to physiological one for a rat heart (4-8 Hz). Material and methods. Cardiomyocytes were isolated by enzymatic digestion from hearts of 3 months old male Wistar-Kyoto rats. The myocytes were electrically paced at 1 Hz, subsequently the frequency of pacing was changed to 4 Hz and gradually increased up to 8 Hz, every 10 sec. Sarcomere shortening was registered as a measure of myocyte contractile performance, by a video-edge detection system. The amplitude and timecourse of the signal were analysed. Results. We did not find the difference between the amplitude of contraction at 1 Hz and at higher frequencies (4-8 Hz). Both the time of contraction development (time-topeak) and relaxation time decreased with increasing pacing frequency. The contribution of the contraction and relaxation phases to the total duration of the cycle did not change after increasing the frequency of pacing to 4 Hz. However, relative lengthening of the contraction phase was observed for higher frequencies, but it did not exceed a few percent. Conclusions. These results indicate that in adult cardiomyocytes isolated from a heart of a young healthy rat, the parameters of contraction-relaxation cycle at low pacing frequency (1 Hz) used in in vitro experiments surprisingly closely correspond with those measured at the frequency near the physiological heart rate.

One of the most important objectives of an economy is to achieve high rate of economic growth so as to improve the well-being of their citizen. For the purpose, export-oriented policy measures are more preferably prescribed in the recent past. The present study aims at to find the linkages between exports and economic growth in case of Saudi Arabia. The study uses the most efficient unit root, cointegration and causality tests to find the true relationships between exports and economic growth. The study tries to examine the dynamic association for exports and economic growth in Saudi Arabia. Applying more popular time series technique of long run relationship and causality, the paper finds the long-run cointegration relationships in our export-growth model. Further, we have found feed-back effect in export-growth relationships and suggest the further export-promotion to foster economic growth in Saudi Arabia.
An Automated Defect Prediction Framework using Genetic Algorithms: A Validation of Empirical Studies

Today, it is common for software projects to collect measurement data through development processes. With these data, defect prediction software can try to estimate the defect proneness of a software module, with the objective of assisting and guiding software practitioners. With timely and accurate defect predictions, practitioners can focus their limited testing resources on higher risk areas. This paper reports the results of three empirical studies that uses an automated genetic defect prediction framework. This framework generates and compares different learning schemes (preprocessing + attribute selection + learning algorithms) and selects the best one using a genetic algorithm, with the objective to estimate the defect proneness of a software module. The first empirical study is a performance comparison of our framework with the most important framework of the literature. The second empirical study is a performance and runtime comparison between our framework and an exhaustive framework. The third empirical study is a sensitivity analysis. The last empirical study, is our main contribution in this paper. Performance of the software development defect prediction models (using AUC, Area Under the Curve) was validated using NASA-MDP and PROMISE data sets. Seventeen data sets from NASA-MDP (13) and PROMISE (4) projects were analyzed running a NxM-fold cross-validation. A genetic algorithm was used to select the components of the learning schemes automatically, and to assess and report the results. Our results reported similar performance between frameworks. Our framework reported better runtime than exhaustive framework. Finally, we reported the best configuration according to sensitivity analysis.
