Organizational Strategy and Corporate Social Responsibility: The Mediating Effect of Triple Bottom Line.

Abstract: Limited research in the area of the triple bottom line (TBL) mediation effect on the relationship between organizational strategic performance (OSP) and corporate social responsibility performance (CSRP) has motivated this study. The objective of this study is to investigate how OSP affects CSRP and the mediation impact of TBL elements through the decision-making process of business management. Considering a sample of 250 employees from Bangladesh, this study used structural equation modelling (SEM) to test the relevant research hypotheses. Through the lens of stakeholder, institutional, legitimacy and resource-based view theories along with rigorous statistical techniques, this study has found that OSP is positively related to CSRP. In terms of the mediation effect, this study has found that economic responsibility has no intervening role while environmental and social responsibility significantly mediated the relationship between OSP and CSRP. Finally, the full mediation power of the model suggests that OSP affects a firm’s strategic decision and CSR outcomes directly as well as indirectly through TBL.

Socio-Economic Conditions of Female Garment Workers in Chittagong Metropolitan Area An Empirical Study

Abstract: This paper is an endeavor to depict the conditions of the female workers from two perspectives. One is social perspective and the other is economic perspective. The analysis is based on the survey of 151 female workers of 29 garment industrial units located in different parts of Chittagong Metropolitan area. This study suggests that the standard of living of the female garment workers is still in precarious condition and they are not free from the vicious circle of poverty and face extreme difficulties in obtaining their basic needs for survival even. This paper recommends measures for improving the prevailing socio-economic facilities, to a great extent, to achieve female workers’ satisfaction at the maximum level. Key Words: Female Garments Workers; Social Factors; Economic Factors. DOI: http://dx.doi.org/10.3329/jbt.v5i2.9935 Journal of Technology (Dhaka) Vol. 5(2), July-December, 2010 53-70

Multifunctional Therapeutic Approach of Nanomedicines against Inflammation in Cancer and Aging

Abstract: Cancer is a fatal disorder that affects people across the globe, yet existing therapeutics are ineffective. The development of submicrometer transport for optimizing the biodistribution of systemically provided medications is the focus of nanomedicine. Nanoparticle- (NP-) based treatments may enable the development of novel therapeutic approaches to combat this deadly disorder. In multifunctional, multimodal imaging, and drug delivery carriers, NPs generally play a major role. They have emerged as potential strategies for the invention of innovative therapeutic procedures in the last decade. The exponential growth of nanotechnologies in recent years has increased public awareness of the application of these innovative therapeutic approaches. Many tumor-targeted nanomedicines have been studied in cancer therapy, and there is clear evidence for a significant improvement in the therapeutic index of antineoplastic drugs. Age-related factors such as metabolic and physiological alterations in old age and inadequate animal models are currently understudied in nanomedicine and pharmacology. This review highlighted the most important targeting approaches, as well as public awareness, therapeutic advancements, and future prospects in age-related metabolic variations, and tumor-targeted nanomedicine studies.

Comprehensive first-principles calculations on physical properties of ScV2Ga4 and ZrV2Ga4 in comparison with superconducting HfV2Ga4

Abstract: We use first-principles method for a comprehensive investigation of structural, elastic, electronic, Mulliken atomic population based bonding, phonon, thermodynamic and optical properties of ScV2Ga4 and ZrV2Ga4 in comparison with the isostructural HfV2Ga4 superconductor. The single and polycrystalline elastic constants are all evaluated and discussed. Cell stability employing elastic constants criteria, formation enthalpy and phonon dispersion are verified. Brittleness and hardness features are also discussed. Elastic anisotropies are evaluated and discussed to unravel some of the macroscopic behaviors of the studied compounds. The significant overlapping between conduction and valence bands in the vicinity of Fermi level (EF) confirms the metallic characteristics for MV2Ga4 (M = Hf, Sc, Zr). It is predicted that the TDOS around the EF arises mostly from V–3d with a smaller contribution of Ga–4p states. The Fermi surfaces show multiband nature but that of ScV2Ga4 has different and complex shape in contrast to ZrV2Ga4 and superconducting HfV2Ga4. The bonding characteristics are analyzed using the energy band structure, charge density distribution and Mulliken atomic and bond overlap population. Such analysis exhibits directional electronic density-channel, highly populated 1D V leashed in (100) plane in the lattices. The formation of such V-chains which accumulate the highest electronic charge might generate Cooper pairs to exhibit superconducting behavior in the yet unobserved Sc and Zr containing compounds. The phonon dispersion curves, phonon density of states and optical phonon frequencies, Raman and infrared activities of the materials are discussed for the first time. The temperature dependent thermodynamic properties including heat capacity at constant pressure are calculated as a function of temperature and compared with the available data. Various optical properties are calculated and their features are analyzed. The potentials of the compounds for practical uses as coating materials to reduce solar heating and enhance radiative cooling are also mentioned.
