Role of the Human Resources Management in Development the Functional Performance for the Jordanian Private Sector Hospitals in Amman City

This study aims to identify the role of the human resources management policies of the (polarization & appointment, training and development, compensation and incentives system, and performance evaluation) to develop and improve the functional performance for the Jordanian private sector hospitals in Amman city. The study population consisted of all the employees in the human resources management in the Jordanian private hospitals at Amman city, were numbered according to Ministry of Health statistics (37) Hospital. This was chosen with a rate of (30%) from the study population, by using the simple random sample method, and the final study sample was amounted (82) employees. The study results indicated that among respondents have a clear vision of the applicable human resources management policies in the Jordanian private sector hospitals in Amman city, and came these policies ordered as its importance (polarization & appointment, training and development, compensation and incentive system, performance evaluation). Also, study results revealed that the evaluation of the study sample for the functional performance was (high) degree, and that they have a clear perceptions about the functional performance for the Jordanian private sector hospitals in Amman city. The results also showed that there was no statistically significant differences in appreciation of the employees on all the human resources management policies in development of the functional performance in the private hospitals in Amman city, attributable to the variables (sex, age, and educational qualification). While shown that there were statistically significant differences in appreciation of the employees for the policy of the (polarization and appointment), attributable to experience years, and in favor of the employees whom their experience years within the class (10-5) years. The results also showed that there was no statistically significant differences in appreciation of the employees on three policies for the human resources management (training and development, compensation and incentive system, performance evaluation), attributed to experience years, while shown that there were significant differences in appreciation of the employees for the policy of the (polarization and appointment, compensation and incentive system) attributable to the functional position variable. While the results indicated that there were no statistically significant differences in appreciation of the employees about the policies (training and development, and performance evaluation) attributable to the functional position variable.
Modeling and Simulation of Graphene Based Polymer Nanocomposites: Advances in the Last Decade

Modeling and simulation allow methodical variation of material properties beyond the capacity of experimental methods. The polymers are one of the most commonly used matrices of choice for composites and have found applications in numerous fields. The stiff and fragile structure of monolithic polymers leads to the innate cracks to cause fracture and therefore the engineering applications of monolithic polymers, requiring robust damage tolerance and high fracture toughness, are not ubiquitous. In addition, when “many-parts” cling together to form polymers, a labyrinth of molecules results, which does not offer to electrons and phonons a smooth and continuous passageway. Therefore, the monolithic polymers are bad conductors of heat and electricity. However, it is well established that when polymers are embedded with suitable entities especially nano-fillers, such as metallic oxides, clays, carbon nanotubes, and other carbonaceous materials, their performance is propitiously improved. Among various additives, graphene has recently been employed as nano-filler to enhance mechanical, thermal, electrical, and functional properties of polymers. In this review, advances in the modeling and simulation of grapheme based polymer nanocomposites will be discussed in terms of graphene structure, topographical features, interfacial interactions, dispersion state, aspect ratio, weight fraction, and trade-off between variables and overall performance.
Global Heat Flow: New Estimates Using Digital Maps and GIS Techniques

The digital geophysical maps and GIS (Geographic Information System) techniques have been employed in obtaining a better understanding of global heat flow. The starting point has been a system of 1o x 1o equal longitude grid consisting of 64800 cells. Superposed on this grid system are a set of 190 polygons that approximates boundaries of tectonic provinces and another set of 137 polygons that outlines age provinces. The area extents of these “tectonic polygons” were determined, and heat flow values calculated based on the empirical relation between heat flow and age of last thermos-tectonic event. Maps derived using such polygon representations reveal a pattern quite similar to that obtained in higher-degree spherical harmonic representations of global heat flow. In addition, an updated assessment of observational data has been carried out and estimated values assigned for cells where observational data are currently unavailable. This practice has been found to provide reasonable bounds in interpolations, leading to better representations of heat flow on a global scale. The mean global heat flow values obtained by this procedure is found to fall in the interval of 58 to 63mW/m². This estimate is lower than that reported in some of the previous studies in which use has been made of theoretical values derived from half-space cooling models as substitutes for experimental data. According to the results of the present work, based on reappraisal of global heat flow database and with due emphasis on observational data, the global conductive heat loss falls in the range of 28 to 35TW. This is nearly 22 to 35% less than those reported in earlier studies.
Incomplete Fiscal Rules with Imperfect Enforcement

This paper analyses the effect of limits on fiscal deficits when fiscal policy outcomes depend on automatic stabilizers and when fiscal rules lack perfect credibility. The model developed, which includes interactions between monetary and fiscal policy, provides theoretical support for existing arguments that fiscal rules contracted on a structural deficit will be welfare-enhancing relative to rules written on the actual deficit. The latter rules would result in a procyclical bias in fiscal policy, as well as a contractionary bias in monetary policy. Contrary to existing arguments, the model also suggests that rules written on the structural deficit may ultimately be more credible than those written on the actual deficit. The reason for this is that rules written on the actual fiscal deficit risk running into a credibility trap; higher marginal penalties will be necessary when initial credibility of enforcement is imperfect, but announcing a higher penalty for violating a fiscal rule can actually reduce credibility if the penalty is disproportionately large relative to the violation.
Restricted Dynamic Programming: Evaluating an Advanced Construction Algorithm in Solving Vehicle Routing Problems

The purpose of this thesis is to evaluate a new and advanced approach for solving Vehicle Routing Problems (VRPs). This approach is based on an exact solution method, dynamic programming, and by restricting its state space, it becomes a heuristic method which could be used in practice. We compared this restricted dynamic programming (RDP) algorithm on both classical and more realistic VRPs with a simple construction algorithm, the savings heuristic. We showed that, while the computation times of the RDP algorithm were exceptionally higher, it did not always gave better solutions than fast construction heuristics and that the claim that the RDP algorithm competes with state of the art local search solutions when more realistic constraints are considered should be rejected. By using two k-opt local search methods to improve the construction solutions, we also discovered that a better construction solution leads to better solutions after the improvement phase. However, because the RDP algorithm could not provide us with high quality construction solutions within reasonable computing time, we can conclude that this new and advanced solution method cannot compete with other known solution methods for the VRP.
Belimumab: therapeutic mechanism and current status of clinical trials

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with diverse clinical features and involving multiple organs leading to highest mortality rate among rheumatic diseases. B cells are responsible and central to the pathogenesis of SLE progression by means of over-aggressive immune response. The complexity of clinical manifestations and unpredictability of the disease are the main hurdles in optimizing treatment for SLE. Recent developments in biological therapy generated hope in SLE patients. Belimumab (Benlysta®) is a complete human monoclonal antibody that is approved for SLE treatment. More or less, belimumab is the first approved biological drug from the Food and Drug Administration, United States (FDA), inhibiting B-cell activating factor/B-lymphocyte stimulator. The present review elucidates the cellular mechanism involved in SLE progression and therapeutic effective of belimumab including clinical trials and clinical outcomes.
Terrestrial trophic subsidy in sandy beaches: evidence from stable isotope analysis in organic matter sources and isopod Excirolana armata

We examined the assimilation of terrestrial organic matter (TOM) by the ovovivipa- rous isopod Excirolana armata inhabiting an exposed sandy beach of Uruguay. The source of this terrestrial input was an artificial freshwater discharge (the Andreoni Canal). We analyzed carbon (δ 13 C) and nitrogen (δ 15 N) isotope ratios in the TOM, in seawater particulate organic matter (POM) and in E. armata at 3 beach sites: Andreoni, at the canal mouth, Coronilla, at 1 km from the mouth and Barra, at 13 km from the mouth. Our analysis revealed clear effects of the canal discharge on the beach ecosystem. TOM was observed in the beach-face detrital mixture only at Andreoni; it also showed the lowest isotopic values there. POM δ 13 C values were also lowest near the canal mouth (increasing with distance from the mouth), indicating the dominance of terrestrial material in the carbon pools of sites closest to the freshwater discharge (viz. Andreoni and Coronilla). The same trend was seen in E. armata. Mixing-model (IsoSource) results for E. armata at Andreoni and Coronilla suggested that TOM was the main contributor to diet at these sites, while POM was the main contributor at Barra. We concluded that E. armata is a useful indicator of TOM assimilation in sandy-beach ecosystems. Our results point up the need, when studying sandy beach food webs, to consider potential modifications by terrestrial alloch thonous inputs.
Identifying shark mating behaviour using three-dimensional acceleration loggers

Little is known about the reproductive strategies and mating behaviour of most sharks. Understanding mating behaviour is important as it can determine reproductive success and possibly rates of multiple paternity and fecundity. Additionally, some sharks appear to have specific habitat requirements for mating activities. We tested the utility of a 3-dimensional acceleration logger to identify mating events in free-living nurse sharks Ginglymostoma cirratum in an area where behav- iours can be observed directly, thus allowing corroboration of acceleration data. Loggers were attached to 4 adult females and were recovered after recording periods of 23.2 to 99.8 h (mean ± SD = 50.0 ± 35.1 h). We used acceleration data to classify several behaviours, including swimming, rest- ing, resting in a surge zone, and mating, with examples of each behaviour confirmed via direct obser- vation. Twenty-six mating events were inferred from acceleration data, ranging from 21 s to 20.1 min in duration (median = 2.22 min), with no events taking place during the nighttime hours between 23:00 and 07:00 h. Four events lasted longer than 9 min and took place during periods when logger- equipped sharks were not acoustically detected within the shallow study site. The similarity in mat- ing behaviours between this and some other species raises the possibility that accelerometry could be used to quantify mating in a variety of shark species. This is the first study to classify mating and other behaviours in free-living sharks from acceleration data.
EFFECT OF PARTICIPATIVE GOVERNANCE AND HUMAN CAPITAL ON THE ORGANIZATIONAL PERFORMANCE OF DAIRY CO-OPERATIVES IN KENYA

Purpose: The purpose of this study was to investigate the effect of participative governance and human capital on the organizational performance of dairy co-operatives in Kenya.Methodology: The study adopted the positivist research philosophy and descriptive correlational research design. The population of the study consisted of 198 executive directors/managers of active dairy co-operatives in eight counties in the Mt. Kenya region. A sample size of 184 was drawn using stratified random sampling, and data was collected using self-administered questionnaires. The data was then analyzed using descriptive statistics of frequency, mean, and standard deviation. Additionally, inferential data analysis methods of Pearson’s correlation, ANOVA, and multiple linear regression were used to test the hypotheses.Results: The results of multiple regression showed that market orientation significantly predicted revenue per customer, b = 1.64, t(141) = 7.66, p < . 05; ROA, b = 2.14, t(141) = 5.9, p < . 05; and product innovation, b =1.89, t(141) = 5.77, p < . 05. Participative governance was not significant in explaining revenue per customer, return on assets, and product innovation. Although the results of multiple regression analysis showed that human capital was not significant in explaining revenue per customer or ROA, it significantly affected product innovation, b = . 94, t(141) = 2.01, p <. 05. In addition, the regression indicated that revenue per customer explained 49.7% of the variance, (R2 = .497, F(5, 125) = 20.10, p < . 05, while ROA explained 29.4 %, (R2 = .294, F(5, 123) = 9.06, p < . 05, and product innovation explained 41.2%, (R2 = 0.412, F(5, 124) = 15.18, p < . 05.Unique contribution to theory, practice and policy: This study contributes to theory of corporate governance by using stewardship theory to underpin research into organizational performance of a member-based agricultural enterprise. The study contributes to practice by suggesting that participation of members and shareholders in organizations may have other benefits, including non-economic ones, but enhancing organizational performance may not be one of them. In terms of policy, the study suggests that dairy co-operatives should put emphasis on acquiring employees with requisite knowledge and skills or their performance may be hamstrung by inadequate intellectual capital to facilitate their innovation and performance.
Effects of Core and/or Peripheral Protonation of meso-Tetra(2-, 3-, and 4-pyridyl)Porphyrin and meso-Tetra(3-methylpyridyl)Porphyrin on Their UV-vis Spectra

Core and/or peripheral protonation of meso-tetra(pyridyl)porphyrins, H2(py)P, with weak and strong acids have been studied by UV-vis spectroscopy. The results support the proposal that the position of the Soret as well as the Q(0,0) bands of the dications is influenced by π donation from the meso substituents to the porphyrin core. The red shift of the Q(0,0) band of H2t(py)P dications with 2-, 3-, and 4-pyridyl substituents does not correlate with the order of π electron donor ability of the meso groups. The decreased electron donation from the central nitrogen atoms to the acids on going from 3-pyridyl group to 4- and 2-pyridyl ones has been used to explain this observation. In spite of the negative effect of N-methylation of pyridyl substituents on the basicity of the central nitrogen atoms of meso-tetra(3-methylpyridyl)porphyrin, H2t(3-Mepy)P, protonation of H2t(3-Mepy)P occurs with weak and strong acids. The blue shift of the Q(0,0) bands upon protonation of H2t(3-Mepy)P with weak and strong acids clearly shows the importance of resonance interactions between the π-systems of porphyrin and the aryl substituents on the position of the band.
A Survey on Graph Queries Processing: Techniques and Methods

Graphs are widely used to model complicated structures and link them with each other. Some of such structures are XML documents, social networks, and computer networks. Information and model extraction from graph databases is a graph mining process. Efficient query search in graph databases, known as query processing, is one of the heated debates in the field of graph mining. One of the query processing techniques is sequential search over the whole dataset and isomorphism test on all sub-graphs in the database, which is not an optimal technique as to response time and storage. This problem brought in the issues of indexing graph databases to improve query processing performance. As the method implies, part of the database where the answer is expected to be found there is pruned and the number of needed isomorphism tests decreases. It might not be easy to compare the methods and techniques of graph query techniques as different techniques have different objectives. For instance, similarity search techniques reduce query time, while they cannot compete with exact matching techniques as to accuracy and vice versa. Input data volume might be also effective on query time as with immense datasets, similarity search techniques are more preferred than exact matching techniques. The present study is a survey of graph query processing techniques with emphasis on similarity search and exact matching.
Debated topics of modern igneous petrology

Progress made thanks to the great amount of high-quality geochemical and isotopic data gathered over the last twenty years has allowed important insights into igneou s petrology ( e . g . , Continental Flood B asalt petrogen e s i s , mantle source characterization, geophysical models of mantle plume systems, primary melt compositions, isotopic systematics of crusta! and mantle domains, etc.) . This large dataset has also been used to relate the compositional characteristics of igneous rocks with specific tectonic settings and to infer the geodynamic processes involved. However, inferring a tectonic setting mainly on the basis of geochemical constraints may fail , because partial melts with substantial compositional differences can originate from the same source, and the same melts may have been generated in d i fferent tectonic se t tings . Moreover, geochemical characterization of the main mantle components is still hotly debated, even in terms of concepts s uch a s as thenosphere and lithosphere . Asthenospheric mantle i s quite often bel ieved to be a geochemical l y homogeneous convecting domain, whereas the lithospheric one is thought to be a variably enriched, heterogeneous, non-convecting reservoir, capable of retaining geochemical and isotopic gradients for periods of time exceeding 2 Ga.

ARTIFICIAL NEUTRAL NETWORKS APPLICATION FOR PLASMA CUTTING MODELING

In order to obtain the required cut quality during plasma cutting process, the particular regularities between the elements of the cutting quality and the process input parameters should be explored. This research should take into consideration the large number of the significant factors that influence the process output parameters. The experimental research in this paper deals with the investigation of the impact of the plasma cutting current, cutting velocity and metal thickness on the kerf surface roughness. Based on the experimental results, the sets of test were done in order to determine the most favourable Artificial Neural Network structure and architecture. The particular Artificial Neural Network process modelling was applied for plasma cutting modelling. The results were verified by the simulation of the Artificial Neural Network which was done by the set of data that was not used for the network training. The simulation was done for the purpose of the verification of the experimental results, where the simulated data showed the good agreement with the experimental results.
Costly State Monitoring and Reserve Requirements

The paper explores one rationale behind the existence of financial repression, with the latter being represented through the obligatory "high" reserve requirement for the banks. Using an overlapping generation production-economy-monetary model characterized by the possibility of banking crisis, we try and answer whether at all these high reserve requirements are related to discipline the banks. Results indicate that economies with higher probability of banking crisis should optimally choose higher income taxation. The correlation between optimal reserve requirements and probability of crisis is positive only when the social planner has exhausted his ability of income taxation.
Derivation and Estimation of a Phillips Curve with Sticky Prices and Sticky Information

I develop a structural model of inflation by combining two different models of price setting behavior: the sticky price model of the New Keynesian literature and the sticky information model of Mankiw and Reis. In a framework similar to the Calvo model, I assume that there are two types of firms. One type of firm chooses its prices optimally through forward-looking behavior---as assumed in the sticky price model. It uses all available information when deciding on prices. The other type of firm sets its prices under the constraint that the information it uses is ``sticky''---as assumed in the sticky information model. It collects and processes the information necessary to choose its optimal prices with a delay. This leads to the sticky price-sticky information (SP/SI) Phillips curve that nests the standard sticky price and sticky information models. Estimations of this structural model show that both sticky price and sticky information models are statistically and quantitatively important for price setting. However, the sticky price firms make up the majority of the firms in the economy. The resultant SP/SI Phillips curve models inflation better than either the sticky price or sticky information models. The results are robust to alternative sub-samples and estimation methods.
