The Role of Humor in Startup Success: The Mediating Role of Team Performance

Entrepreneurial ventures have high rates of failure in converting an idea to a business. We seek to understand the role of humor to sustain ventures. Research shows us that humor plays a critical role in team performance. A strong team can overcome the initial hiccups of a startup and increase the chances of success. This study benchmarks the level of humor, then does an intervention of a “humor training session,” and measures its effects. We theorize that there will be an increase in team performance due to stress reduction, which will lead to a likelihood of survival of the startup

RISK FACTORS ASSOCIATED WITH NEURODEVELOPMENTAL DISORDERS IN HIGH SOCIOECONOMIC STATUS FAMILIES: BRIEF INDIAN ANALYSIS

This study seeks to identify parental prenatal, perinatal and postnatal risk factors of Neurodevelopmental Disorders (NDD) in comparison to Typically Developing (TD) children, all from high Socioeconomic Status (SES) families. A unified definition of NDD in terms of delays in development was employed for the purpose of this study. SES was understood as an important variable in the context of NDD. We employed a cross-sectional/comparative two-group survey design. It included parents of 60 children: 32 children with NDD and 28 children with TD. The developmental assessment was conducted for all the children for their classification into NDD and TD groups. Results depicted significant differences in the family history of mental illness or NDD, perinatal factors rather than prenatal and postnatal factors. On measures of association and variance, composite perinatal factors were observed to have a small effect on NDD, while the pre and postnatal showed a negligible impact. The interpretation and its application for improving the prevalence of NDD in high SES families in an Indian urban set-up were discussed

Managing Security in the Built Environment – A Review of Environmental Crime Prevention Strategies

The practice of urban planning and building design largely follow traditional methods while transforming the structure and quality of life in the built environment. The process of managing cities requires updates and integration of new technologies and research efforts. In this context, development of smart, sustainable, energy efficient, healthy, safe and secure built environment is a priority that is shaping modern cities all over the world. Though management of Indian cities tries to address these issues to a certain extent, it can be said that, as compared to many developed countries, aspects of safety and security have not been the top priority of our planners and designers. Research on Environmental Criminology and Environmental Psychology clearly indicates the important role and benefits of crime prevention through appropriate design of the built environment. In this context, this paper highlights the role of crime prevention strategies and the relevance of environmental criminology in current building practices for addressing security concerns in India

Assessment of knowledge, attitude and practices of universal precautions among medical and nursing students

Background: Universal precautions is an approach to infection control to treat all human blood and certain human body fluids as if they were known to be infectious for HIV, HBV and other bloodborne pathogens. The CDC recommends Standard Precautions for the care of all patients, regardless of their diagnosis or presumed infection status. Health care personals are at risk of being exposed to blood-borne pathogens. The aim of the study to determine the knowledge, attitude and practice of medical and nursing students towards universal precautions.Methods: A cross-sectional survey was carried out at S. S. Institute of Medical Sciences and Research Centre, Davangere, Karnataka. The participants were medical and Nursing undergraduate students. A questionnaire was prepared based on the WHO and CDC guidelines on Universal Precautions and was validated and pre-tested before finalization. Degree of knowledge was ascertained by means of yes-no questions on each item being evaluated.Results: All students were aware of Universal precautions, but soundness of their knowledge is very poor. Compliance in Universal precautions is good to average in nursing students but poor to average in medical students.Conclusions: It can be concluded that interventions to improve Universal precautions among medical students, nursing students urgently needed. So, there is a need for developing strategies to promote the use of Universal precautions which take into account behaviour change and accuracy of knowledge including its integration into practice. Teaching universal precautions early in their curriculum is necessary for better learning and practices during their posting

Modeling views in the layered view model for XML using UML

In data engineering, view formalisms are used to provide flexibility to users and user applications by allowing them to extract and elaborate data from the stored data sources. Conversely, since the introduction of Extensible Markup Language (XML), it is fast emerging as the dominant standard for storing, describing, and interchanging data among various web and heterogeneous data sources. In combination with XML Schema, XML provides rich facilities for defining and constraining user-defined data semantics and properties, a feature that is unique to XML. In this context, it is interesting to investigate traditional database features, such as view models and view design techniques for XML. However, traditional view formalisms are strongly coupled to the data language and its syntax, thus it proves to be a difficult task to support views in the case of semi-structured data models. Therefore, in this paper we propose a Layered View Model (LVM) for XML with conceptual and schemata extensions. Here our work is three-fold; first we propose an approach to separate the implementation and conceptual aspects of the views that provides a clear separation of concerns, thus, allowing analysis and design of views to be separated from their implementation. Secondly, we define representations to express and construct these views at the conceptual level. Thirdly, we define a view transformation methodology for XML views in the LVM, which carries out automated transformation to a view schema and a view query expression in an appropriate query language. Also, to validate and apply the LVM concepts, methods and transformations developed, we propose a view-driven application development framework with the flexibility to develop web and database applications for XML, at varying levels of abstraction

High resolution human leukocyte antigen (HLA) class I and class II allele typing in Mexican mestizo women with sporadic breast cancer: case-control study

<p>Abstract</p> <p>Background</p> <p>The development of breast cancer is multifactorial. Hormonal, environmental factors and genetic predisposition, among others, could interact in the presentation of breast carcinoma. Human leukocyte antigen (HLA) alleles play an important role in immunity (cellular immunity) and may be important genetic traits. HLAAllele-specific interaction has not been well established. Recently, several studies had been conducted in order to do so, but the results are controversial and in some instances contradictory.</p> <p>Methods</p> <p>We designed a case-control study to quantify the association of HLA class I and II genes and breast cancer. HLA typing was performed by high resolution sequence-specific oligotyping after DNA amplification (PCR-SSOP) of 100 breast cancer Mexican mestizo patients and 99 matched healthy controls.</p> <p>Results</p> <p>HLA-A frequencies that we were able to observe that there was no difference between both groups from the statistical viewpoint. HLA-B*1501 was found three times more common in the case group (OR, 3.714; <it>p </it>= 0.031). HLA-Cw is not a marker neither for risk, nor protection for the disease, because we did not find significant statistical differences between the two groups. DRB1*1301, which is expressed in seven cases and in only one control, observing an risk increase of up to seven times and DRB1*1602, which behaves similarly in being present solely in the cases (OR, 16.701; 95% CI, 0.947 – 294.670). DQ*0301-allele expression, which is much more common in the control group and could be protective for the presentation of the disease (OR, 0.078; 95% CI, 0.027–0.223, <it>p </it>= 0.00001).</p> <p>Conclusion</p> <p>Our results reveal the role of the MHC genes in the pathophysiology of breast cancer, suggesting that in the development of breast cancer exists a disorder of immune regulation. The triggering factor seems to be restricted to certain ethnic groups and certain geographical regions since the relevant MHC alleles are highly diverse. This is the first study in Mexican population where high resolutions HLA typing has been performed in order to try to establish an association with malignancy.</p

Cell Lineage Analysis of the Mammalian Female Germline

Fundamental aspects of embryonic and post-natal development, including maintenance of the mammalian female germline, are largely unknown. Here we employ a retrospective, phylogenetic-based method for reconstructing cell lineage trees utilizing somatic mutations accumulated in microsatellites, to study female germline dynamics in mice. Reconstructed cell lineage trees can be used to estimate lineage relationships between different cell types, as well as cell depth (number of cell divisions since the zygote). We show that, in the reconstructed mouse cell lineage trees, oocytes form clusters that are separate from hematopoietic and mesenchymal stem cells, both in young and old mice, indicating that these populations belong to distinct lineages. Furthermore, while cumulus cells sampled from different ovarian follicles are distinctly clustered on the reconstructed trees, oocytes from the left and right ovaries are not, suggesting a mixing of their progenitor pools. We also observed an increase in oocyte depth with mouse age, which can be explained either by depth-guided selection of oocytes for ovulation or by post-natal renewal. Overall, our study sheds light on substantial novel aspects of female germline preservation and development
