Human resource management in India: strategy, performance and complementarity

This study seeks to explore which types of HR practice are associated with better organisational performance (OP). Whilst the core finding—that specific HR practices lead to better organisational outcomes may not be surprising—we also found an absence of complementarity. Normally, the absence of complementarities would suggest limitations in institutional supports; on the one hand, however, institutional shortfalls are not unique to India and may be encountered in many emerging market settings. In contrast, the great internal diversity of the Indian setting, with strong variations recognised amongst institutions, along with enforcement capabilities, might suggest that these tendencies are particularly pronounced. We also found a strong link between the intrinsic rewards and performance—an unexpected result in a low-income country, where wages are generally low. We suggest that this may reflect the nature of the labour market and the limited (and possibly proportionately shrinking) pool of good jobs, making exit a difficult option for all but the best qualified. Whilst this puts employees in a poor bargaining position in bidding-up pay (making pay rises seem unfeasible), the intrinsic attributes of the job become more important

Spin observables for pion photoproduction on the deuteron in the Δ\Delta(1232)-resonance region

Spin observables for the three charge states of the pion for the pion photoproduction reaction on the deuteron, $\gamma d\to\pi NN$, with polarized photon beam and/or oriented deuteron target are predicted. For the beam-target double-spin asymmetries, it is found that only the longitudinal asymmetries $T_{20}^{\ell}$ and $T_{2\pm 2}^{\ell}$ do not vanish, whereas all the circular and the other longitudinal asymmetries do vanish. The sensitivity of spin observables to the model deuteron wave function is investigated. It has been found that only $T_{21}$ and $T_{22}$ are sensitive to the model deuteron wave function, in particular in the case of $\pi^0$-production above the $\Delta$-region, and that other asymmetries are not.Comment: 16 pages, 8 figures, accepted for publication in J.

Diabetes mellitus: The epidemic of the century

The epidemic nature of diabetes mellitus in different regions is reviewed. The Middle East and North Africa region has the highest prevalence of diabetes in adults (10.9%) whereas, the Western Pacific region has the highest number of adults diagnosed with diabetes and has countries with the highest prevalence of diabetes (37.5%). Different classes of diabetes mellitus, type 1, type 2, gestational diabetes and other types of diabetes mellitus are compared in terms of diagnostic criteria, etiology and genetics. The molecular genetics of diabetes received extensive attention in recent years by many prominent investigators and research groups in the biomedical field. A large array of mutations and single nucleotide polymorphisms in genes that play a role in the various steps and pathways involved in glucose metabolism and the development, control and function of pancreatic cells at various levels are reviewed. The major advances in the molecular understanding of diabetes in relation to the different types of diabetes in comparison to the previous understanding in this field are briefly reviewed here. Despite the accumulation of extensive data at the molecular and cellular levels, the mechanism of diabetes development and complications are still not fully understood. Definitely, more extensive research is needed in this field that will eventually reflect on the ultimate objective to improve diagnoses, therapy and minimize the chance of chronic complications development

Challenges of soil carbon sequestration in the NENA region

The Near East North Africa (NENA) region spans over 14&thinsp;% of the total surface of the Earth and hosts 10&thinsp;% of its population. Soils of the NENA region are mostly highly vulnerable to degradation, and future food security will much depend on sustainable agricultural measures. Weather variability, drought and depleting vegetation are dominant causes of the decline in soil organic carbon (SOC). In this work the status of SOC was studied, using a land capability model and soil mapping. The land capability model showed that most NENA countries and territories (17 out of 20) suffer from low productive lands (&gt;&thinsp;80&thinsp;%). Stocks of SOC were mapped (1:5 000 000) in topsoils (0–0.30&thinsp;m) and subsoils (0.30–1&thinsp;m). The maps showed that 69&thinsp;% of soil resources are shown to have a stock of SOC below the threshold of 30&thinsp;tons&thinsp;ha−1. The stocks varied between  ≈ 10&thinsp;tons&thinsp;ha−1 in shrublands and 60&thinsp;tons&thinsp;ha−1 for evergreen forests. Highest stocks were found in forests, irrigated crops, mixed orchards and saline flooded vegetation. The stocks of soil inorganic carbon (SIC) were higher than those of SOC. In subsoils, the SIC ranged between 25 and 450&thinsp;tons&thinsp;ha−1, against 20 to 45&thinsp;tons&thinsp;ha−1 for SOC. Results highlight the contribution of the NENA region to global SOC stock in the topsoil (4.1&thinsp;%). The paper also discusses agricultural practices that are favorable to carbon sequestration such as organic amendment, no till or minimum tillage, crop rotation and mulching and the constraints caused by geomorphological and climatic conditions. The effects of crop rotations on SOC are related to the amounts of above and belowground biomass produced and retained in the system. Some knowledge gaps exist, especially in aspects related to the impact of climate change and effect of irrigation on SOC, and on SIC at the level of the soil profile and soil landscape. Still, major constraints facing soil carbon sequestration are policy-relevant and socioeconomic in nature, rather than scientific.</p

Effects of Propolis, Ascorbic Acid and Vitamin E on Thyroid and Corticosterone Hormones in Heat Stressed Broilers

The study was designed to evaluate the effect of oxidative stress during the summer on serum levels of Triiodothyronine (T3), thyroxine (T4) and corticosterone hormones in Ross 308 broiler chickens and to compare the efficacy of propolis, ascorbic acid and vitamin E (α-tocopherol acetate) as antioxidants in amelioration of heat stress and normalization of serum T3 and T4 and corticosterone levels in broilers. Birds were divided into five groups during the experimental period (15 to 42 days of age), the positive control group (G1) was kept under thermo-neutral condition (28.0±4.0°C ) and fed control diet, while the other four groups were exposed to heat stress (38.0±1.4°C), control group (G2) chicks were fed control diet without additives, propolis group (G3) chicks were supplemented with 250 mg Chinese ether extracted propolis /kg diet, group (G4) supplemented with 250 mg ascorbic acid/kg diet and group (G5) supplemented with 250 mg of α-tocopherol acetate/kg diet (vitamin E). At the end of day 42, five broilers were randomly chosen from each treatment and slaughtered, and then sera were collected to estimate T3 and T4 and corticosterone levels. The results indicated that dietary supplementation of broilers with 250 mg/kg diet propolis, vitamin E or vitamin C can attenuate heat stress induced oxidative damage. These positive effects were evidenced by reduced serum corticosterone levels and improvement in thyroid hormonal levels in comparison to non-supplemented birds reared under heat stress

A Time-Space Tradeoff for Triangulations of Points in the Plane

In this paper, we consider time-space trade-offs for reporting a triangulation of points in the plane. The goal is to minimize the amount of working space while keeping the total running time small. We present the first multi-pass algorithm on the problem that returns the edges of a triangulation with their adjacency information. This even improves the previously best known random-access algorithm

Predicting Online Islamophobic Behavior after #ParisAttack

The tragic Paris terrorist attacks of November 13, 2015 sparked a massive global discussion on Twitter and other social media, with millions of tweets in the first few hours after the attacks. Most of these tweets were condemning the attacks and showing support for Parisians. One of the trending debates related to the attacks concerned possible association between Muslims and terrorism, which resulted in a world-wide debate between those attacking and those defending Islam. In this paper, we use this incident as a case study to examine using online social network interactions prior to an event to predict what attitudes will be expressed in response to the event. Specifically, we focus on how a person’s online content and network dynamics can be used to predict future attitudes and stance in the aftermath of a major event. In our study, we collected a set of 8.36 million tweets related to the Paris attacks within the 50 hours following the event, of which we identified over 900k tweets mentioning Islam and Muslims. We then quantitatively analyzed users’ network interactions and historical tweets to predict their attitudes towards Islam and Muslims. We provide a description of the quantitative results based on the tweet content (hashtags) and network interactions (retweets, replies, and mentions). We analyze two types of data: (1) we use post-event tweets to learn users’ stated stance towards Muslims based on sampling methods and crowd-sourced annotations; and (2) we employ pre-event interactions on Twitter to build a classifier to predict post-event stance. We found that pre-event network interactions can predict attitudes towards Muslims with 82% macro F-measure, even in the absence of prior mentions of Islam, Muslims, or related terms

Evaluation of Glycated Hemoglobin (HbA1c) for Diagnosing Type 2 Diabetes and Prediabetes among Palestinian Arab Population

The purpose of the study is to compare the potential of HbA1c to diagnose diabetes among Palestinian Arabs compared to fasting plasma glucose (FPG). A cross-sectional sample of 1370 Palestinian men (468) and women (902) without known diabetes and above the age of 30 years were recruited. Whole blood was used to estimate HbA1c and plasma for FPG and total lipid profile. Fasting plasma glucose was used as a reference to diagnose diabetes ($126 mg/dL) and prediabetes (100–125 mg/dL). The area under the receiver operating characteristic curve (AUC) for HbA1c was 81.9diabetes and 63.90.498) and low with prediabetes (K = 0.142). The optimal cut-off value for HbA1c to diagnose diabetes was$ 6.3% (45 mmol/mol). The sensitivity, specificity and the discriminant ability were 65.6% (53.1–76.3%), 94.5% (93.1–95.6%), 80.0% (72.8–87.3%), respectively. However, using cut-off value of $6.5the sensitivity, specificity and the discriminant ability were 57.4For diagnosing prediabetes with HbA1c between 5.7–6.4discriminant ability were 62.7value of$ 6.5% (48 mmol/mol) by itself diagnosed 5.3% and 48.3% as having diabetes and prediabetes compared to 4.5% and 24.2% using FPG, respectively. Mean HbA1c and FPG increase significantly with increasing body mass index. In conclusion, the ROC curves showed HbA1c could be used for diagnosing diabetes when compared to FPG but not for prediabetes in Palestinians Arabs even though only about 50% of the diabetic subjects were identified by the both HbA1c and FPG.This project was partially supported by United Nation Relief and Working Agency (UNRWA.

The Effect of Chinese Propolis Supplementation on Ross Broiler Performance and Carcass Characteristics

The experiment was conducted to investigate the effects of Ether Extract of Propolis (EEP) on Ross (308) broiler performance and carcass characteristics. This experiment was carried out in a completely randomized design with 5 treatments (different levels of propolis including 0, 100, 250, 500 and 750 mg/kg diet) for 6 weeks. The mean weight gain, feed consumption and feed conversion ratio were recorded weekly. In addition At 42 days old the total body weight, total body weight gain, carcass and some internal organs relative weights were recorded. The results clarified that, the weight gain was significantly reduced in the 4th and 6th week (P&lt;0.05), while the feed consumption, feed efficiency were non significantly (P&gt;0.05) reduced for propolis fed birds in comparison to those fed control diet, Furthermore, inclusion of 100, 250, 500 and 750 mg/kg diet Propolis significantly reduced body weight at 42 days old and total body weight gain in comparison to control diet (P &lt; 0.05). Under the condition of this experiment, prolonged use of propolis had adverse effect on performance of broilers. Also, all doses of propolis had non-significant negative effect on liver, heart, gizzard and carcass relative weight. In conclusion, EEP has no beneficial effect on performance and Carcass characteristics of Broilers
