Importance and performance of managerial training in Indian companies – an empirical study

Purpose – The purpose of this paper is to compare the importance and performance of managerial training in India among different industrial sectors in the light of asynchronous industrial growth in last two decades which has unevenly touched various business organizations. Design/methodology/approach – For the purpose of analysis organizations are divided at two levels. At the first level, they are divided between multinational and Indian origin category and at the second level between service and manufacturing category. A 2×2 full factorial design with unequal numbers is used to analyze main as well as interaction impacts. A sample size of 542 is taken which comprises training professionals, top/general managers and trainee employees. Findings – Study concludes that Indian origin organizations fall short in terms of importance given and performance of training function compared to multinational companies. Further, it is found that service companies have an edge over manufacturing companies in terms of im.
Seroprevalence of Aspergillus fumigatus antibodies in bovine herds with a history of reproductive disorders

Bovine reproductive disorders are of growing interest from both economic and health standpoints. The role that fungi play in these processes is becoming increasingly important. Study of the seroprevalence of anti-Aspergillus antibodies in cow sera taken from herds with previous reproductive disorders is therefore of great interest. We used an indirect ELISA technique, that had shown suitable results in previous studies in other animal species. Thirteen percent of the 387 animals tested in the current study were positive, accounting for 41% of herds. When this technique was applied to the sera of two fetuses, that were aborted due to aspergillosis, a sig - nificant difference in anti- Aspergillus antibody levels was found compared with those in control sera. The ELISA technique was compared with PLATELIA and PCR for 24 ELISA-positive cattle sera; these assays resulted in only one and three positive results, respectively. In conclusion, the ELISA analysis showed a significant seroprevalence of Aspergillus antibodies in herds with previous reproductive disorders. There is therefore a need for more atten - tion to be paid to Aspergillus in the differential diagnoses of these conditions and to improve preventive methods to effectively control this organism.
Job Search Processes for Tribal People From Jharkhand and West Bengal

Millions of job seekers in South Asia, including many tribals, are forced by lack of local employment opportunities to migrate towards urban areas. This fieldwork-based study aims to understand specifically which factors influence job search processes among tribals from two states in India—Jharkhand and West Bengal. It examines their reasons for moving and factors on which job search depends, methods adopted in job search, the extent of different options and limitations because of the nature of jobs available and the skills levels of the people concerned. Based on these ethnographic findings, some policy concerns are raised in terms of monitoring of migration and protection of food security for tribal communities and other structurally disadvantaged rural people in South Asia.
Relationship of Folate, Vitamin B-6, Vitamin B-12, and Methionine Intake to Incidence of Colorectal Cancers

It is hypothesized that diets deficient in folate, methionine, and vitamins B-6 and B-12 cause DNA hypomethylation and, as a result, increase risk of colorectal cancers. Furthermore, it is proposed that alcohol, a methyl group antagonist, increases risk of colorectal cancers among those with low intake of folate. Data from the Iowa Women's Health Study, a population-based cohort of incident cancer, were used to examine the relationship of folate, methionine, and vitamins B-6 and B-12 to occurrence of cancers of the colon (n = 598) and rectum (n = 123) over 13 yr of follow-up. There were no independent associations of folate, methionine, or vitamins B-6 and B-12 derived from a food frequency questionnaire with incidence of colon cancer. Adjusted relative risks (RRs) of rectal cancer were similar across categories of folate, vitamin B-12, and methionine intake, but RRs increased progressively with increasing intake of vitamin B-6 [P (for trend) = 0.03]. RRs suggested that incidence of cancer of the proximal colon was lower among those with 1) high folate and high vitamin B-12 intake [RR = 0.59, 95% confidence interval (CI) = 0.39-0.89] and 2) high folate and high vitamin B-6 intake (RR = 0.65, 95% CI = 0.50-0.84) than among those with the lowest intake of these nutrients. Incidence of cancer of the proximal colon was also somewhat lower among those with high folate and low alcohol intake (RR = 0.44, 95% CI = 0.22-0.89). Findings provide limited support for an association between dietary factors involved in DNA methylation and risk of cancers of the colon and rectum.
The Impossible Role of Teacher Educators in a Changing World

The thesis of this article is that the external demands placed on teacher education at the present time, combined with inherent professional needs of teachers and student teachers, create a nearly impossible situation for teacher educators. The article starts with a brief analysis of some of the external demands and constraints on teacher education: globalization, professionalization, and the call of many experts to teach for understanding. These external demands are exacerbated by teachers’ needs for certainty and control, and the frequent gaps between teachers’ professional self-images and the demands of their teaching contexts also contribute to the complexities of the role of teacher educators. The article concludes with a discussion of the societal implications of the current situation.

Application of a marker of ciliated epithelial cells to gynaecological pathology.

BACKGROUND: The assessment of neoplastic disease in gynaecological histopathology can be complicated by the high incidence of metaplasia seen in tissues of the female genital tract. There is a need to identify specific tissue markers which can be applied in routine histopathological practice. AIM: To examine the clinical potential of a monoclonal antibody, LhS28, which reacts with basal bodies of ciliated epithelial cells. METHODS: A panel of normal and pathological gynaecological tissues was processed and labelled with LhS28. RESULTS: LhS28 immunoreactivity was found in the normal Fallopian tube where it was confined to ciliated rather than secretory epithelial cells. In the remaining specimens, LhS28 was associated exclusively with ciliated cells in tubal metaplasias of the cervix and endometrium and in benign serous lined inclusion cysts. CONCLUSIONS: LhS28 may be a valuable marker for identifying metaplasia of tubal type and may find application in distinguishing tubal metaplasia from low grade cervical glandular intraepithelial neoplasia.
The Effect of Active Teaching and Subject Content Coverage on Students' Achievement: Evidence from Primary Schools in Kenya.

There is a growing public concern in Kenya over the persistent gap between those schools that are consistently ranked at the top and those ranked at the bottom of the annual Kenya Certiﬁcate of Primary Education (KCPE) examination league tables. This has raised the issue of inequality in educational opportunity. Our primary concern in this paper is to understand some of the classroom–school factors that may explain the persistent differences in achievement between the top and bottom schools. We focus on time-on-task (the length of exposure to any particular teaching and learning task) and cur- riculum content, and ask whether this explains the difference in performance. We test the following hypotheses: differences exist on teachers’ time-on-task between low and high performing schools; greater teacher time-on-task has a positive effect on student gain score; and greater content coverage has a positive effect on student achievement. For the student achievement gains, we use item response theory test scores of 1889 Grade 6 pupils from 70 schools in Kenya. Data on time-on-task were generated from 70 maths les- sons observed in these schools, while content coverage was developed from students’ maths note books for the entire period they were in Grade 6. The study was conducted by a team of researchers at the African Population and Health Research Center (APHRC) with funding from Google.org. Using two level hierarchical modelling, we control for pupil, teacher and school factors. Results show that exposure to content is positively correlated with pupil gain scores (gain score is the difference in score between test at time t1 and test at time t2 of the same pupil taught by the same teacher). Maths teachers in both bottom and top performing schools spend the same proportion of time-on-task. However, we do not ﬁnd that time-on-task is related to achievement in this sample. no and for This explores further in the context of Kenya the relationship that exists between time, content coverage and achievement. It does this through the analysis of classroom observation videos of 72 schools from across the coun-try, randomly chosen within low and bottom performing schools categories in the Kenya Certiﬁcate of Primary Education (KCPE) examination taken at the end of the eight years primary cycle, and which is used for selecting pupils into the various categories of secondary schools across the The objective is to establish if there are differences in the active strategies and coverage that persistent difference in pupil achievement in top and bottom performing categories of schools. The rest of the presents a summary of literature relevant This is followed by presentation on the including and and ﬁnally conclusion recommendations.
Impacts of diaspora travel on ethnic identity development among 1.5 generation Korean-American college students

This research project was designed to explore the impacts of the most recent trip to Korea on ethnic identity development among 1.5 generation Korean-American college students. The study employed 18 in-depth semi-structured interviews with Korean-American college students at a major university in the Midwest, USA. The data collection was conducted between December 2010 and February 2011. The findings of the study revealed that Korean-American college students exhibited different levels of ethnic identity prior to their most recent trip to Korea and described themselves as either Koreans, Korean-Americans, or Americans. Travel to Korea played important roles in (re)developing their ethnic identity. Those who identified themselves as Korean prior to the trip either confirmed their ethnic identity or changed their identity to Korean-American. Those who considered themselves Korean-American retained their ethnic identity, while those who thought of themselves as American altered their identity to Korean as a result of the travel.
Training Large Scale Deep Neural Networks on the Intel Xeon Phi Many-Core Coprocessor

As a new area of machine learning research, the deep learning algorithm has attracted a lot of attention from the research community. It may bring human beings to a higher cognitive level of data. Its unsupervised pre-training step allows us to find high-dimensional representations or abstract features which work much better than the principal component analysis (PCA) method. However, it will face problems when being applied to deal with large scale data due to its intensive computation from many levels of training process against large scale data. The sequential deep learning algorithms usually can not finish the computation in an acceptable time. In this paper, we propose a many-core algorithm which is based on a parallel method and is used in the Intel Xeon Phi many-core systems to speed up the unsupervised training process of Sparse Autoencoder and Restricted Boltzmann Machine (RBM). Using the sequential training algorithm as a baseline to compare, we adopted several optimization methods to parallelize the algorithm. The experimental results show that our fully-optimized algorithm gains more than 300-fold speedup on parallelized Sparse Autoencoder compared with the original sequential algorithm on the Intel Xeon Phi coprocessor. Also, we ran the fully-optimized code on both the Intel Xeon Phi coprocessor and an expensive Intel Xeon CPU. Our method on the Intel Xeon Phi coprocessor is 7 to 10 times faster than the Intel Xeon CPU for this application. In addition to this, we compared our fully-optimized code on the Intel Xeon Phi with a Matlab code running on single Intel Xeon CPU. Our method on the Intel Xeon Phi runs 16 times faster than the Matlab implementation. The result also suggests that the Intel Xeon Phi can offer an efficient but more general-purposed way to parallelize the deep learning algorithm compared to GPU. It also achieves faster speed with better parallelism than the Intel Xeon CPU.
Spectrum occupancy analysis of cooperative relaying technique for cognitive radio networks

Dynamic Spectrum Access (DSA) is a successful solution for the spectrum scarcity problem. In DSA, unlicensed users can gain access to licensed spectrum in a way that does not harm the licensed transmission. Many technical solutions are proposed to efficiently facilitate DSA. This paper analyzes the benefits of using cooperative relaying technique on the spectrum occupancy for the unlicensed transmissions. A slotted access with interweave spectrum sharing is modeled using stationary discrete time Markov chains for both non-cooperative and cooperative unlicensed transmissions. Furthermore, the effect of the cooperation level among the unlicensed users on the achieved throughput is investigated. The results show that the mechanism of cooperative relaying is more efficient in utilizing the unused spectrum especially in crowded spectrum. Moreover, the relative average throughput increases as the cooperation increases due to efficient utilization of the spectrum holes.
Developing an assessment for learning (AfL) culture in school: the voice of the principals

This study reflects the voice of school leaders (principals) in a Norwegian school development project focusing on assessment for learning (AfL). The central role of the principal in school improvement is well documented, however, less is written about how the principals themselves see their roles. The voices presented belong to two experienced principals from two elementary schools in Norway. The schools participated in a three-year-action-oriented development project aimed at establishing an AfL culture. Towards the end of the project, the principals shared their experiences in a semi-structured group interview. The findings support the central role principals play in successful implementation of change. However, their role is not sufficiently appreciated and taken into account.
LATS1 and LATS2 Phosphorylate CDC26 to Modulate Assembly of the Tetratricopeptide Repeat Subcomplex of APC/C

In budding yeast, the Mitotic Exit Network (MEN) regulates anaphase promoting complex/cyclosome (APC/C) via the Dbf2-Cdc14 signaling cascade. Dbf2 kinase phosphorylates and activates Cdc14 phosphatase, which removes the inhibitory phosphorylation of the APC/C cofactor Cdh1. Although each component of the MEN was highly conserved during evolution, there is presently no evidence supporting direct phosphorylation of CDC14 by large tumor suppressor kinase 1 (LATS1), the human counterpart of Dbf2; hence, it is unclear how LATS1 regulates APC/C. Here, we demonstrate that LATS1 phosphorylates the Thr7 (T7) residue of the APC/C component CDC26 directly. Nocodazole-induced phosphorylation of T7 was reduced by knockdown of LATS1 and LATS2 in HeLa cells, indicating that both of these kinases contribute to the phosphorylation of CDC26 in vivo. The T7 residue of CDC26 is critical for its interaction with APC6, a tetratricopeptide repeat-containing subunit of APC/C, and mutation of this residue to Asp (T7D) reduced the interaction of CDC26 with APC6. Replacement of endogenous CDC26 in HeLa cells with exogenous phosphor-mimic T7D-mutated CDC26 increased the elution size of APC/C subunits in a gel filtration assay, implying a change in the APC/C assembly upon phosphorylation of CDC26. Furthermore, T7D-mutated CDC26 promoted the ubiquitination of polo-like kinase 1, a well-known substrate of APC/C. Overall, these results suggest that LATS1/2 are novel kinases involved in APC/C phosphorylation and indicate a direct regulatory link between LATS1/2 and APC/C.
The Governance of Nonprofit Organizations: Empirical Evidence From Nongovernmental Development Organizations in Spain

To verify the existence and relevance of control mechanisms that impede the expropriation of resources by the managers of nonprofits and that improve efficiency, we use a representative sample of Spanish nongovernmental development organizations (NGDOs). The authors study how the donors’ structure and board of trustees relates to organizational efficiency. Results show that the presence of an active institutional donor provides a control mechanism for these NGDOs, thus favoring the efficient allocation of resources, and that the structure of the board of trustees is irrelevant in this respect. Results are robust to alternative measures of technical and allocative efficiency.
Socioeconomic Status and Depression: The Role of Occupations Involving Direction, Control, and Planning

This article proposes a social causation explanation for the association between SES and depression/distress. The model links SES, occupational direction, control, and planning (DCP), personality factors, and depression/distress in a causal sequence. The data to test the social causation model against alternative, social selection models are derived from samples of psychiatric patients and community residents in Washington Heights, New York City. The key factor of DCP is operationalized using ratings from the Dictionary of Occupational Titles. The results support the social causation model and cannot be accounted for by several tests derived from social selection models. Thus the results increase the plausibility of the social causation model and suggest the need for further research on the links between occupational conditions and mental disorder.
Role of phenylalanine 150 in the receptor-binding domain of the K88 fibrillar subunit

Recently, we reported the isolation of three peptides, Ile-83-Ala-Phe-85, Ser-148-Leu-Phe-150, and Ala-156-Ile-Phe-158, derived from the K88 fibrillar subunit and found to inhibit the binding of K88 fibrillae to cavia erythrocytes or pig intestinal epithelial cells (A. A. C. Jacobs, J. Venema, R. Leeven, H. van Pelt-Heerschap, and F. K. de Graaf, J. Bacteriol. 169:735-741, 1987). The gene encoding the K88 fibrillar adhesin was modified by oligonucleotide-directed site-specific mutagenesis such that each of the phenylalanine residues at positions 85, 150, and 158 were replaced by serine. Replacement of phenylalanine 85 or 158 had no apparent effect on the biosynthesis of the fibrillae or on their adhesive capacity. In contrast, substitution of phenylalanine 150 with serine resulted in a dramatic decrease in adhesive capacity of the K88 fibrillae. Apparently, phenylalanine 150 plays an essential role in the interaction of the adhesin with receptor molecules present on eucaryotic cells.
Understanding situated survey refusal: applying sensemaking and sensegiving to ethnostatistics

This study develops a behind-the-scenes understanding of the people and organizations that are depended upon to provide survey data. A data collection event— in this study, a pilot coverage measurement survey conducted after the United States 2010 Census—provides an ideal environment to gauge respondents’ reactions to the survey process. Relying on the conceptual guidance of script formation, these reactions are studied using a focus group and interviews with staff. Using a combination of constant comparative method and ethnographic theme analysis the results generated a grounded theory of situated refusal that identifies specific scripts that respondents used when completing a self-administered survey. The findings describe the role of sensegiving and sensemaking in the fluid decision-making context of survey participation. The major themes for sensemaking include time, redundancy, and education, while the themes for sensegiving are organizational messages and organizational relationships. In addition to this contribution to qualitative and survey research, this study also provides a cognitive perspective on the current understanding of ethnostatistics—the qualitative study of quantitative processes.
Regional impacts of iron-light colimitation in a global biogeochemical model

Abstract. Laboratory and field studies have revealed that iron has multiple roles in phytoplankton physiology, with particular importance for light-harvesting cellular machinery. However, although iron-limitation is explicitly included in numerous biogeochemical/ecosystem models, its implementation varies, and its effect on the efficiency of light harvesting is often ignored. Given the complexity of the ocean environment, it is difficult to predict the consequences of applying different iron limitation schemes. Here we explore the interaction of iron and nutrient cycles in an ocean general circulation model using a new, streamlined model of ocean biogeochemistry. Building on previously published parameterizations of photoadaptation and export production, the Biogeochemistry with Light Iron Nutrients and Gasses (BLING) model is constructed with only four explicit tracers but including macronutrient and micronutrient limitation, light limitation, and an implicit treatment of community structure. The structural simplicity of this computationally-inexpensive model allows us to clearly isolate the global effect that iron availability has on maximum light-saturated photosynthesis rates vs. the effect iron has on photosynthetic efficiency. We find that the effect on light-saturated photosynthesis rates is dominant, negating the importance of photosynthetic efficiency in most regions, especially the cold waters of the Southern Ocean. The primary exceptions to this occur in iron-rich regions of the Northern Hemisphere, where high light-saturated photosynthesis rates allow photosynthetic efficiency to play a more important role. In other words, the ability to efficiently harvest photons has little effect in regions where light-saturated growth rates are low. Additionally, we speculate that the phytoplankton cells dominating iron-limited regions tend to have relatively high photosynthetic efficiency, due to reduced packaging effects. If this speculation is correct, it would imply that natural communities of iron-stressed phytoplankton may tend to harvest photons more efficiently than would be inferred from iron-limitation experiments with other phytoplankton. We suggest that iron limitation of photosynthetic efficiency has a relatively small impact on global biogeochemistry, though it is expected to impact the seasonal cycle of plankton as well as the vertical structure of primary production.
