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 (1232)-resonance region
Spin observables for the three charge states of the pion for the pion
photoproduction reaction on the deuteron, , 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
and 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 and are sensitive to the model deuteron wave
function, in particular in the case of -production above the
-region, and that other asymmetries are not.Comment: 16 pages, 8 figures, accepted for publication in J. Phys. G: Nucl.

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

Challenges of soil carbon sequestration in the NENA region
The Near East North Africa (NENA) region spans over 14 % of the
total surface of the Earth and hosts 10 % 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
(> 80 %). Stocks of SOC were mapped (1:5 000 000) in
topsoils (0–0.30 m) and subsoils (0.30–1 m). The maps showed that
69 % of soil resources are shown to have a stock of SOC below the threshold of
30 tons ha−1. The stocks varied between ≈ 10 tons ha−1
in shrublands and 60 tons 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 tons ha−1,
against 20 to 45 tons ha−1 for SOC. Results highlight the contribution
of the NENA region to global SOC stock in the topsoil (4.1 %). 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
Stress- and phospholipid signalling responses in Arabidopsis PLC4-KO and -overexpression lines under salt- and osmotic stress
Several drought and salt tolerant phenotypes have been reported when overexpressing (OE) phospholipase C (PLC) genes across plant species. In contrast, a negative role for Arabidopsis PLC4 in salinity stress was recently proposed, showing that roots of PLC4-OE seedlings were more sensitive to NaCl while plc4 knock-out (KO) mutants were more tolerant. To investigate this apparent contradiction, and to analyse the phospholipid signalling responses associated with salinity stress, we performed root growth- and phospholipid analyses on plc4-KO and PLC4-OE seedlings subjected to salinity (NaCl) or osmotic (sorbitol) stress and compared these with wild type (WT). Only very minor differences between PLC4 mutants and WT were observed, which even disappeared after normalization of the data, while in soil, PLC4-OE plants were clearly more drought tolerant than WT plants, as was found earlier when overexpressing Arabidopsis PLC2, -3, -5, -7 or -9. We conclude that PLC4 plays no opposite role in salt-or osmotic stress and rather behaves like the other Arabidopsis PLCs
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 ( 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 6.5% (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. No additional external funding received for this study. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript
