Genetic diversity in threatened plant species Alnus nitida (Spach.) Endel

Alnus nitida (Spach) Endl. is an ethnobotanically important threatened plant species. The genetic diversity among the 50 different genotypes of Alnus nitida was carried out using sodium dodecyl sulfate poly acrylamide gel electrophoresis (SDS-PAGE) characterization. A considerable amount of genetic diversity (90%) was observed among the genotypes of A. nitida. The protein characterization was carried out on 12% gel electrophoresis. A total of 10 protein bands were detected in A. nitida genotypes. SDS-PAGE procedure is a useful method for the investigation of both genetic diversity and phylogenetic relationship. Especially, B-5 was monomorphic in A. nitida genotypes and was considered as species specific. All other bands/loci were polymorphic. These polymorphic bands displayed 12, 16, 72, 88, 2, 44, 84, 54 and 12 percent variation respectively. In the present examination, the high intra-specific diversity was observed representing SDS-PAGE is a powerful tool for determining the genetically diverse germplasms in A. nitida. The results obtained by this study could be helpful in the identification and selection of desired genotypes of Alnus nitida for conservation programmes in future. Today, there is still a need to assess genetic variation and protect genetic resources, especially of wild species for prospective benefits in plant conservation programmes

Quantitative assessment and status of ethnomedicinal plants of Sheen Ghar Valley, Dir Lower, Khyber Pakhtunkhwa, Pakistan

This study was conducted from March 2017 to August 2018, to enumerate the quantitative attributes and current status of medicinal plants of Sheen Ghar Valley, District Dir Lower, Pakistan. A total of 51 species were documented for their medicinal uses. These plants belonged to 31 families. Results of this study revealed that leaves were the frequently used part (50%), followed by whole plants (only 30%) in curing different ailments. Many plants were found to be having multiple uses. Based on family importance value (FIV), Lamiaceae was the leading plant family (126.30) followed by Violaceae (55.81), while highest relative frequency of citation (RFC) was noted for Viola canescens (0.558) followed by Olea europaea (0.523). Conservation study revealed that 24 species (47%) were vulnerable, 22 species (43%) were rare and 4 species (8%) were noted as infrequent. Following IUCN standards for conservation, one species i.e. Hypericum perforatum was declared dominant. This study recommends immediate ex-situ and in-situ conservation programme for protecting the plant wealth of the locality

Social support: mediating the emotional intelligence-academic stress link

IntroductionThis study examines the relationship between emotional intelligence (EI) and academic stress among tertiary-level students who continued academic activities remotely during the pandemic and the mediating role of social support (SS) in the relationship.MethodsUsing a cross-sectional survey design, 429 students studying business, engineering, social science, and science in Bangladesh provided data via Qualtrics. Using the Structural Equation Modeling in SmartPLS 4 (4.0.8.9), we modeled emotional intelligence as the reflective-formative and social support (support from family, friends, and significant other) and perceived academic stress as the reflective-reflective, second-order constructs. We also conducted a one-way between-groups analysis of variance (ANOVA) to investigate the impact of gender (male and female) and current stage of academic study (Undergraduate year one to four and post-graduation) on emotional intelligence and academic stress, respectively.Results and discussionResults show that all the hypothesized relationships are statistically significant: EI is negatively related to perceived academic stress, and SS significantly mediates the relationship between EI and academic stress. Hence, essential strategies are suggested to help students for managing academic stress

Advancing the model of social entrepreneurial intention: the role of perceived financial security

Purpose – Although few studies indicate that financial concerns matter to social entrepreneurs, the literature is unclear about the extent to which a financial motive affects the intention to start a new social enterprise. Moreover, prior research suggests that the intention to start a new enterprise heavily depends on the societal context in which the enterprise operates. Therefore, this study aims to examine the seminal model of social entrepreneurial intention (SEI) developed by Hockerts (2017) in a different social context; additionally, it proposes a new antecedent of SEI – perceived financial security. Design/methodology/approach – This study used two different measurement scales and samples (n = 436 and 241) in a developing country to validate the model and propose a new antecedent, i.e. the perceived financial security, of SEI. Furthermore, the authors employed the partial least square-structural equation model to test the hypotheses. Findings – The results demonstrate that social entrepreneurial self-efficacy, perceived social support and perceived financial security directly predict SEI; they further mediate the relationship between prior experience and SEI. Consequently, the model by Hockerts is extended. Originality/value – This study established perceived financial security as a strong antecedent of SEI, thereby offering a novel insight that a social entrepreneur can be motivated by potential financial concerns

FDI and Export Linkage Revisited: The Case of Bangladesh

This empirical research examines the export effect of foreign direct investment (FDI) with reference to Bangladesh economy. An export supply function extended with the FDI variable has been employed with panel data. Econometric estimations unveil clear-cut contribution of inward FDI to boost export. Thus, this study ascertains that FDI and export are positively related to each other which mean trade and factor flows act as complements. Under such circumstance, higher growth of FDI will promote export growth
