EXAMINING THE ROLE OF HUMAN RESOURCE MANAGEMENT IN RETAINING TEACHING EMPLOYEES:A CASE STUDY IN SISTAN AND BALUCHESTAN PROVINCE EDUCATIONAL CENTER

Basically, employees’ retention is a fundamental problem in every organization. Thus, executive agencies seek to reduce employee turnover, particularly qualitative resources (skilled and capable human resources). This issue is considerably important in education. This study aimed to investigate the role of human resource management in employees’ retention. The research objective is developmental applied type. Method: The subjects were selected using stratified random sampling method proportional to statistical population. For this purpose, a survey was conducted using descriptive and analytical method. Data collection tool was a questionnaire. Statistical sample size was obtained as 317 employees of High School in Zahedan based on Morgan Table. The subjects were selected using stratified random sampling method proportional to statistical population. The questionnaire was designed based on Likert Scale. Data analysis was performed using statistical methods, Pearson correlation coefficients and SPSS. Content validity was examined by experts in a preliminary study while reliability was examined using test-retest method. Retesting with a predetermined interval and obtaining similar results indicated reliability of the test. Results: The results showed that there is a significant and positive relationship between studied factors and employees’ retention. In other words, all components play an important role in employees’ retention. Thereby, it is recommended that education department and other relevant agencies put on agenda detailed plans for human resource development as well as appropriate methods to retain staff.
25-hydroxy Vitamin D Status in Healthy Korean School Children and Adolescents: Striking Difference in Prevalence of Vitamin D Deficiency with School Grade and Season

Purpose: The aim of this study was to investigate the prevalence of vitamin D deficiency according to school grade and season in healthy Korean children and adolescents. Method: We screened for vitamin D deficiency using serum 25-hydroxyvitamin D (25-OHD) combined with anthropometric and laboratory findings. Findings: Vitamin D deficiency was present in 72.3% of study subjects and prevalence of vitamin D deficiency was higher in girls than in boys (76.6 vs 66.9%). During spring and winter, serum 25-OHD levels were found to be lower compared with other seasons. The prevalence of vitamin D deficiency was highest (87.4%) in high school students and followed by middle school (78.8%) and elementary school students (70.5%). The predictors for vitamin D deficiency were female, winter/spring seasons and high school students. Conclusion: Adequate outdoor activities and/or oral vitamin D supplements during winter and spring seasons should be necessary in female adolescents.
Denseness and Zariski denseness of Jones braid representations

Using various tools from representation theory and group theory, but without using hard classification theorems such as the classification of finite simple groups, we show that the Jones representations of braid groups are dense in the complex Zariski topology when the parameter $t$ is not a root of unity. As first established by Freedman, Larsen, and Wang, we the same result when t is a non-lattice root of unity, other than one initial case when t has order 10. We also compute the real Zariski closure of these representations. When such a representation is indiscrete in the analytic topology, then its analytic closure is the same as its real Zariski closure.
LIGNIN STRUCTURE AND WOOD PROPERTIES

The objective of this study was to understand the relationship between lignin structural organization and certain wood properties. Lignin, which constitutes 20-30% of the weight of all woody plants, functions as a binding and encrusting material in the cell wall, giving rigidity to the overall plant structure. More than 60% of all linkages in lignins isolated (Bjorkman) from Aspidosperma macro-carpum, Lophanthera lactescens, Gallesia gorazema, Peltogyne paniculata , and Aspidosperma polyneuron were of the β-O-4 alkyl aryl ether type. This unit plays an important role in the physical and mechanical properties of wood. Percentages of β-O-4 unit were estimated by infrared spectroscopy. An Index of Molecular Flexibility (IMF) was introduced in order to hypothetically estimate the contribution of this unit toward wood flexibility, (under the assumption that the β-O-4 linkage is positively correlated with flexibility). Lignins from Aspidosperma macrocarpum (AM) and Aspidosperma poly-neuron (AP) show the highest and lowest structural complexity (diversity of linkage types β-β, β-5, β-O-4, etc.) with IMF values of 2.02 and 3.00, respectively. In this case, lignins AM and AP are supposedly contributing toward lowest and highest grade of wood flexibility, respectively, which demonstrates the hypothesis that β-O-4 linkages correlate well with flexibility.
Black Holes in Born-Infeld Extended New Massive Gravity

In this paper we find different types of black holes for the Born-Infeld extended new massive gravity. Our solutions include (un)charged warped (anti-)de Sitter black holes for four and six derivative expanded action. We also look at the black holes in unexpanded Born-Infeld action. In each case we calculate the entropy, angular momentum and mass of the black holes. We also find the central charges for the conformal field theory duals.
A methodology for assessing the impacts of enhanced rail services in South East Europe

Rail transport in South East Europe (SEE) has received limited attention, although its role remains important for future transport sustainability. Albeit general efforts towards making rail competitive to other transport modes, the latter has become less attractive in recent years. For this reason, the recently initiated “Rail4SEE – Rail Hub Cities for South East Europe” project, financed by the EU, examines the introduction of enhanced rail services on a transnational level, and their impacts on future modal choice. In this paper, a methodology is presented for quantifying the impacts of such services in terms of modal shift and for evaluating their overall contribution towards rail transport enhancement in a transnational level. Insights are given on the modal split model development, the data requirements at a transnational level and the parameters of a rail trip chain that are influenced by such services (e.g. access, transfer or travel time). The outcomes of the applied methodology will be expressed as the overall number of trips conducted with each mode and reveal the contribution of such services to rail transport enhancement.
Senaps: A platform for integrating time-series with modelling systems

: Models of physical systems are the foundation of many scientific and decision support systems. These models rely heavily on observational data, typically collected from sensors. Increasingly this data comes from a wide range of sources. For example, agricultural models often require data from climate observations, soil conditions, on-farm equipment, seasonal forecasts, among others. Integration of these data with models is very time-consuming and often is repetitious across different models. Furthermore, automation of model runs is difficult due to the complexity of managing data dependencies. We have developed a distributed system, Senaps, to support automation of sensor data retrieval and coupling with model execution in a scalable way. It has been developed over many years across scientific disciplines, including water management, agriculture, aquaculture, and related Information, Communication and Technologies areas. It has been used, and is in use, by a diverse range of projects, resulting in a flexible system that is not tied to a specific domain. Senaps includes a publish-subscribe subsystem that handles ingestion of disparate time-series data. It supports stream processing, such as quality assurance and data checking, and automates data ingestion with monitoring and recovery. The storage and access subsystem is a scalable time-series backend with an Application Programming Interface (API) to allow third party developers to build on. It has a range of features including dynamic temporal aggregations; fine-grained access control to support data privacy and sharing (users can elect to share data between organisations); metadata for sensor data management; and controlled vocabularies. The focus of this paper is the model integration subsystem, which provides the model integration and automation features. This system builds on developments in cloud and container-based computing to isolate a user submitted model’s runtime environment and provide access to the data backend. APIs are provided to handle environment images (e.g. Linux with R), model definition, workflows (instances of a model), and running of model jobs. We have successfully used this system to automate model runs and provide continuous results from a number of parameterised models. We have hosted a number of models on the platform, including a timber drying model and two agricultural prediction models. Being tied to a robust sensor-data backend ensures models are run on the most recent data and removes the need for model developers to continuously manage model execution. Results from the model are automatically available and can be easily shared between users and organisations. In this paper, we detail the technical challenges in implementation, provide example results from a running model, and describe our next research steps.
Legitimising Information Security Policy during Policy Crafting: Exploring Legitimising Strategies

This study examines the crafting of an information security policy as a process of legitimising. Drawing on organisational research on legitimacy and legitimisation and on 15-month ethnographic study of a multinational corporation that sought to craft a new policy, the study identifies four legitimising strategies employed during policy crafting: (1) inviting participation, (2) embedding into existing practices, (3) advertising and (4) formalising and professionalising. The study conceptualises policy crafting as being constituted through iterative and recursive relationship of legitimising strategies and policy amendments. The study contributes to literature on information security management, on information security policies and on legitimacy.
Triggering Solidarity Actions towards Contingent Workers and the Unemployed. The Point of View of Grassroots Trade Unionists and Labour Activists

Since the 1980s, trade unions have suffered a decrease in membership, public legitimacy and the capacity to achieve their core objectives. Renewal strategies have varied, depending on the national context. Part of them focused on rank-and-file mobilization and social movement unionism. In the Greek context, the academic discussion about the crisis of trade unions took place mainly during the 2000s, but without having an impact within union circles or on union strategies. Additionally, grassroots and rank-and-file unions that adopted a social movement and radical unionism approach, and contested the 'institu-tionalized official' trade unions, remained marginal and their actions were not very visible. The recent fis-cal crisis and the implementation of the Memoranda brought up previous dysfunctions. In a context of in-creasing employment precarity and unemployment, the general position of official trade unions towards contingent workers and the unemployed has been strongly contested, while grassroots rank-and-file un-ions claim a more active role in this area. Given the above considerations, this article focuses on the strat-egies of trade unions towards contingent workers and the unemployed, in the Greek context. Results de-rive from interviews with Greek grassroots trade unionists and labour activists in the framework of the TransSOL (Transnational Solidarity at Times of Crisis) EU-funded program.
The Impact of Obesity on Some Hormones and the Cognitive Function among School Girls

The number of obese children has increased considerably worldwide and childhood obesity causes many problems that can track into adulthood. The current study was conducted on 45 obese girls (mean age±SE =10.53±1.29 years; mean BMI±SE =28.43± 4.62 Kg/m 2 ) in addition to 45 age- and sex-matched controls (mean age±SE =10.36±1.53 years; mean BMI±SE =19.07±3.47 Kg/m 2 ). Estimation of serum ghrelin and growth hormone (GH), plasma leptin, insulin, and insulin-like growth factor-1 (IGF-1) as well as cognitive functions (auditory vigilance, digit span, coding ability and visual memory) were carried out. The levels of plasma leptin, insulin and IGF-1 showed highly significant increase whereas those of serum ghrelin and GH showed highly significant decrease in the obese group as compared with the control group. The total right response of auditory vigilance (TR) showed insignificant decrease while the total wrong response of auditory vigilance (TW) showed significant increase in the obese group as compared with the control group. Digit span showed highly significant decrease while coding scores showed significant increase. Visual memory recall showed insignificant decrease while visual memory classification showed highly significant decrease in the obese group as compared with the control group. Obesity in school girls affected the levels of the measured hormones as well as the cognitive function of these girls which reflect the high impact of obesity on these subjects.

Diabetes distress and related factors in South African adults with type 2 diabetes

Background: In South Africa, the prevalence rate of diabetes is 9.27%, with an estimated 2.6 million people living with the disease. Diabetes-related distress has been described as encompassing the patient’s concerns about the self-management of diabetes, perception of support, emotional burden and access to quality health care. There has been little or no research done in South Africa regarding diabetes-related distress. Objectives: The aim of this paper was: (1) to identify the level of diabetes-related distress in a cohort of diabetes type 2 patients in KwaZulu-Natal and (2) to identify the factors that contribute to diabetes-related distress. Methods: This cross-sectional study was conducted at two public facilities and five private medical practices on the north coast of KwaZulu-Natal, South Africa. The Diabetes Distress Scale was administered, together with a demographic questionnaire, to 401 participants. Results: In total, 44% of the sample reported having moderate to high levels of distress. The mean scores of the Emotional Burden dimension (M = 2.6; SD = 1.42) and the Regimen Distress dimension (M = 2.33; SD = 1.29) suggested moderate levels of distress. Factors that significantly contributed to high levels of distress were younger age, high HbA1C levels, female gender, attending the public health sector, unemployment and being a person of colour. Conclusion: Healthcare providers need to pay particular attention to the psychological needs of the patient, which impact on the medical outcomes of the disease.
Surface brightness profile of the Milky Way’s nuclear star cluster

Context. Although the Milky Way nuclear star cluster (MWNSC) was discovered more than four decades ago, several of its key properties have not been determined unambiguously up to now because of the strong and spatially highly variable interstellar extinction toward the Galactic centre. Aims. In this paper we aim at determining the shape, size, and luminosity/mass of the MWNSC. Methods. To investigate the properties of the MWNSC, we used Spitzer/IRAC images at 3:6 and 4:5 m, where interstellar extinction is at a minimum but the overall emission is still dominated by stars. We corrected the 4:5 m image for PAH emission with the help of the IRAC 8:0 m map and for extinction with the help of a [3:6 4:5] colour map. Finally, we investigated the symmetry of the
Influence of Temperature and Salinity on Food Conversion and Growth of Different Nereis Species (Polychaeta, Annelida)

Feeding experiments in 15 and 30 "/W salinity reveal similar food conversion rates of Nereis succinea and N. diversicolor at high temperature (15 "C). At low temperature (5 'C) food conversion of N. diversicolor is more efficient. A salinity increase from 15 to 30 '/(m S facilitates better food conversion in both species leading to an increased energy content (exception: N. succinea at 5 "C and 30 "/<V* S). N. diversicolor exhibits better food conversion at low temperature, generally higher production rates, lower gross energy demand for production and a lower maintenance metabolism at 15 "/U& S in comparison with N. succinea. This suggests that N, diversicolor is better fitted to the specific environmental conditions of the Baltic Sea than N. succinea. A comparison of assimilation efficiencies and gross growth efficiencies of different species showed an increase in the sequence N. succinea, N. diversicolor and N. virens.
Preservation of spatial coherence of an optical pulse in atomic vapor quantum memory

We report on the preservation of transverse spatial coherence of an optical pulse stored in atomic vapor quantum memory. The high visibility Young-type spatial fringes formed by interference between the retrieved and the delayed optical pulses clearly demonstrate that the atomic vapor quantum memory based on electromagnetically induced transparency preserves transverse spatial coherence. This demonstration has important implications in quantum imaging and multimode quantum information processing.
Performance analysis of a new radial-axial flux machine with SMC cores and ferrite magnets

Soft magnetic composite (SMC) is a popular material in designing of new 3D flux electrical machines nowadays for it has the merits of isotropic magnetic characteristic, low eddy current loss and high design flexibility over the electric steel. The axial flux machine (AFM) with the extended stator tooth tip both in the radial and circumferential direction is a good example, which has been investigated in the last years. Based on the 3D flux AFM and radial flux machine, this paper proposes a new radial-axial flux machine (RAFM) with SMC cores and ferrite magnets, which has very high torque density though the low cost low magnetic energy ferrite magnet is utilized. Moreover, the cost of RAFM is quite low since the manufacturing cost can be reduced by using the SMC cores and the material cost will be decreased due to the adoption of the ferrite magnets. The 3D finite element method (FEM) is used to calculate the magnetic flux density distribution and electromagnetic parameters. For the core loss calculation, .
Quantitative Easing and the Liquidity Channel of Monetary Policy

How do central bank purchases of illiquid assets affect interest rates and the real economy? In order to answer this question, I construct a parsimonious and very flexible general equilibrium model of asset liquidity. In the model, households are heterogeneous in their asset portfolios and demand for liquidity, and asset trade is subject to frictions. I find that open market purchases of illiquid assets are fundamentally different from helicopter drops: asset purchases stimulate private demand for consumption goods at the expense of demand for assets and investment goods, while helicopter drops do the reverse. A temporary program of quantitative easing can therefore cause a 'hangover' of elevated yields and depressed investment after it has ended. When assets are already scarce, further purchases can crowd out the private flow of funds and cause high real yields and disinflation, resembling a liquidity trap. In the long term, lowering the stock of government debt reduces the supply of liquidity but increases the capital-output ratio. The consequences for output are ambiguous in theory but a calibration to US data suggests that the liquidity effect dominates; in other words, the supply of Treasuries is 'too small'.
Describing Compartmentalization in the Fore-wing of Populations of the Rice Grasshoppers, Oxya sp. (Acrididae: Orthoptera)

The fore-wings of Rice grasshoppers, Oxya sp. are divided into compartments by a complex network of veins. There has been a long term hypothesis suggesting that wing compartments bounded by veins may correspond to distinct cell lineages and domains of gene expression. Hence, this study was conducted to determine the patterns of modularity and integration in the fore-wings of the Rice grasshoppers, Oxya sp. A total of 180 points were used to outline the margins of the fore-wings. Results showed that the fore-wing of Oxya sp. is partitioned into 6 developmental modules. The consistency in the number and pattern of developmental modules in the fore-wings suggests that the wings are highly conserved indicating genetic conservatism in the morphological spaces. Results also suggest that compartments are considered an autonomous unit of gene regulation and major veins served as boundaries and as active center of integration.
Characterization of heavily doped polysilicon films for CMOS-MEMS thermoelectric power generators

This paper presents the material characterization of boron- and phosphorus-doped LPCVD polysilicon films for the application of thermoelectric power generators. Electrical resistivity, Seebeck coefficient and thermal conductivity of polysilicon films doped with doses from 4 × 1015 to 10 × 1015 at cm−2 have been measured at room temperature. Specific contact resistance between polysilicon and aluminum is studied and nickel silicidation is formed to reduce the contact resistance. The overall thermoelectric properties, as characterized by the figure of merit, are reported for polysilicon doped with different doping concentrations. For the most heavily doping dose of 10 × 1015 at cm−2, figure of merit for p- and n-type polysilicon is found as 0.012 and 0.014, respectively. Based on the characterization results, a CMOS compatible thermoelectric power generator composed of boron- and phosphorus-doped polysilicon thermopiles is fabricated. When 5 K temperature difference is maintained across two sides of a device of size of 1 cm2, the output power is 1.3 µW under a matched electrical resistance load.
