    Get PDF
    Social media is the gathering place of a large pool of consumers. It is the repository of consumer information and acts as a means of spreading information to build market presence. Most literature states that organizational usage of social media enhances customer relations, but social media also acts as a medium for information acquisition. Not many previous studies have investigated the role of social media on information accessibility. Therefore this study examined the impact of social media on information accessibility. A total of 171 organization responded to the survey and the result of the survey showed that social media usage has a positive impact on information accessibility. Also it was found that factors such as interactivity, trust and institutional pressure positively influence social media usage in organizations. This study provided a clearer understanding on the real importance of social media and its benefits towards information acquisition. The results would motivate and guide organizations in the adoption of social media for information acquisition which is important for understanding the customers, competitors and the industry and to develop strategies for enhancing business performance

    In order to define the period of maturity of penaeid shrimps at least three indices (fecundity, size structure and density of mature females) are required. During the present study the relationships between fecundity and total length, carapace length, ovary length, body weight and ovary weight of three species of Penaeid shrimps, Penaeus (Fenneropenaeus) indicus, Penaeus (Marsupenaeus) japonicus and Penaeus (Penaeus) monodon were found out. Samples of shrimps were collected from fish market, identified to the species level, morphometric measurements of each individual were recorded and the fecundity of each developed shrimp was estimated. The relationship between body weight and fecundity and between body length and fecundity were linear in all three species. The result indicated positive strong correlation between total length (size) and fecundity in all three species. Positive strong correlations were observed between carapace length and the fecundity, ovary length and fecundity,body weight and fecundity and ovary weight and fecundity in P. indicus and P. monodon while Penaeus japonicus showed moderate positive correlations between all mentioned morphometric parameters and fecundity. There was a strong correlation between fecundity and body length in Penaeus japonicus (r =0.880), fecundity and ovary weight in Penaeus indicus (r = 0.943) and fecundity and carapace length in Penaeus monodon (r = 0.970). The estimated fecundity of Penaeus indicus varied between 989073.36 to 1380581.565 eggs for body length range 14.4 to 20.1 cm while that of Penaeus japonicus varied between 249602.2609 to 320026.71 eggs for length range 15.4 to 19.4 cm and fecundity of Penaeus monodon, with body length range 14.4 to 21.1 cm, varied between 221271.6 to 400296.288 eggs

    Impact of physical distance and psychological distress on job turnover intention among front-line health workers during COVID-19 pandemic

    Get PDF
    COVID-19 pandemic compels strict isolation to avoid the spread of Coronavirus. Physical distance with COVID-19 patients is undeniable for font-line health workers. This physical proximity of doctors and nurses at hospital affects their mental health and generating psychological distress. They sacrifice their social life and keeping themselves isolated due to their regular contact with COVID-19 patients. This causes high rate of depression, anxiety and stress. Therefore, this study aims to identify the effect of physical distancing and psychological distress on job turnover intention among the front line health workers. This study is applying Protection Motivation Theory (PMT) to understand this relationship. Data has been collected between March and April 2021 through structured questionnaire from doctors, nurses and hospital staffs who are managing COVID-19 patients at hospitals. This research has discovered that as front-line health workers' fear of COVID-19 grows, so does their relational anxiety, as well as their organizational and technical turnover intentions. Therefore, there is a need of psychological assistance and increasing capacity building for the front-line workers. This study includes only two variables to understand job turnover intention. For more insights and understanding of the experience in the light of COVID-19, further study can be done by including other factors like institutional support, policy implementation and social dilemma

    Biallelic variants in CHST3 cause Spondyloepiphyseal dysplasia with joint dislocations in three Pakistani kindreds

    Get PDF
    Background Skeletal dysplasia is a heterogeneous group of disorders. Spondyloepiphyseal dysplasias comprise one subgroup. Deficiency of carbohydrate sulfotransferase 3 has been reported in a small number of patients with recessively inherited spondyloepiphyseal dysplasia with joint dislocation, short stature and scoliosis. We report here molecular and clinical findings of affected individuals in three consanguineous Pakistani families. Affected individuals in all three families had a uniform phenotype including severe short stature, multiple dislocated joints, progressive scoliosis and facial dysmorphism. Methods Clinical evaluation was done for three unrelated families. Radiological survey of bones was completed for patients from two of the families. Whole exome sequencing index patients from each family was performed followed by Sanger sequencing for validation of segregation of identified variants in respective families. In-silico analysis for determining pathogenicity of identified variants and conservation was done. Results Whole-exome sequencing revealed biallelic variants c.590 T > C;p.(Leu197Pro), c.603C > A;p.(Tyr201Ter) and c.661C > T;p.(Arg221Cys) in CHST3 (NM_004273.5) in the three families with eight, five and two affected individuals, respectively. Contrary to previous reports, affected individuals in none of the families exhibited a hearing loss. Conclusion We describe genotypic and phenotypic findings of three unrelated families with spondyloepiphyseal dysplasia. Our study confirms phenotypic variability and adds to the genotypic spectrum of spondyloepiphyseal dysplasia.Peer reviewe

    Background: Health planning in developing countries differs from developed countries. They have more limited resources for health development. Therefore efficient health planning and resource allocation is critical to ensure optimal health outcome of the nation. Due to the nature of heterogeneity among the developing countries, the health approach may differ contextually among developing countries. This paper aims to compare practices of health planning development among selected developing countries. Materials and Methods: This review encompasses relevant scientific articles and most recent official country report related to health planning. Searches only include articles or reports published in English. Based on the six WHO regions. Selection of countries based on availability of manuscript (article and report) fulfilling the criteria. The countries selected were Bangladesh, Belize, Jordan, Kenya, Malaysia and Turkey. Result: A five or ten years of strategic plan for health is the most practiced among the studied developing country. It usually involves multi-sectorial within the country and international agencies and consultants. The advancement of technology helps in improving the administrative data utilisation to allow informed-decision making, deeper root cause analysis and timely monitoring and evaluation. Other than that, engagement with various stakeholders from different level – at all phase of plan development, together with political will is the key factor of the successful implementation. Despite that, these developing countries often suffer from limited resources in term of workforce, financing and technical expertise. Conclusion: Although the health planning process is similar across countries studies, where the cycles start with situational analysis, prioritisation, options appraisal, implementation, monitoring and lastly evaluation. Each country may have slightly different approaches, depending on their context, resources and technology capacity

    RORγt+ innate lymphoid cells promote lymph node metastasis of breast cancers

    Get PDF
    Cancer cells tend to metastasize first to tumor-draining lymph nodes, but the mechanisms mediating cancer cell invasion into the lymphatic vasculature remain little understood. Here, we show that in the human breast tumor microenvironment (TME), the presence of increased numbers of RORγt+ group 3 innate lymphoid cells (ILC3) correlates with an increased likelihood of lymph node metastasis. In a preclinical mouse model of breast cancer, CCL21-mediated recruitment of ILC3 to tumors stimulated the production of the CXCL13 by TME stromal cells, which in turn promoted ILC3–stromal interactions and production of the cancer cell motile factor RANKL. Depleting ILC3 or neutralizing CCL21, CXCL13, or RANKL was sufficient to decrease lymph node metastasis. Our findings establish a role for RORγt+ILC3 in promoting lymphatic metastasis by modulating the local chemokine milieu of cancer cells in the TME
