This paper aims to introduce a robust framework for forecasting demand, including data preprocessing, data transformation and standardization, feature selection, cross-validation, and regression ensemble framework. Bagging ), boosting and extreme gradient boosting regression ), and stacking are employed as ensemble models. Different machine learning approaches, including support vector regression, extreme learning machine, and multilayer perceptron neural network, are adopted as reference models. In order to maximize the determination coefficient value and reduce the root mean square error, hyperparameters are set using (...) the grid search method. Using a steel industry dataset, all tests are carried out under identical experimental conditions. In this context, STACK1 and STACK2 models provided better performance than other models. The highest accuracies of R2 of 0.97 and 0.97 are obtained using STACK1 and STACK2, respectively. Moreover, the rank according to performances is STACK1, STACK2, XGBR, GBR, RFR, MLP, ELM, and SVR. As it improves the performance of models and reduces the risk of decision-making, the ensemble method can be used to forecast the demand in a steel industry one month ahead. (shrink)

When it is ethically justifiable to stop medical treatment? For many Muslim patients, families, and clinicians this ethical question remains a challenging one as Islamic ethico-legal guidance on such matters remains scattered and difficult to interpret. In light of this gap, we conducted a systematic literature review to aggregate rulings from Islamic jurists and juridical councils on whether, and when, it is permitted to withdraw and/or withhold life-sustaining care. A total of 16 fatwās were found, 8 of which were single-author (...) rulings, and 8 represented the collective view of a juridical council. The fatwās are similar in that nearly all judge that Islamic law, provided certain conditions are met, permits abstaining from life-sustaining treatment. Notably, the justifying conditions appear to rely on physician assessment of the clinical prognosis. The fatwās differ when it comes to what conditions justify withdrawing or withholding life- sustaining care. Our analyses suggest that while notions of futility greatly impact the bioethical discourse regarding with holding and/or withdrawal of treatment, the conceptualization of futility lacks nuance. Therefore, clinicians, Islamic jurists, and bioethicists need to come together in order to unify a conception of medical futility and relate it to the ethics of withholding and/or withdrawal of treatment.

BackgroundThe pharmaceutical market in Bangladesh is highly concentrated. Due to high competition aggressive marketing strategies are adopted for greater market share, which sometimes cross limit. There is lack of data on this aspect in Bangladesh. This exploratory study aimed to fill this gap by investigating current promotional practices of the pharmaceutical companies including the role of their medical representatives.MethodsThis qualitative study was conducted as part of a larger study to explore the status of governance in health sector in 2009. Data (...) were collected from Dhaka, Chittagong and Bogra districts through in-depth interview, observation, and round table discussion.ResultsFindings reveal a highly structured system geared to generate prescriptions and ensure market share instituted by the pharmaceuticals. A comprehensive training curriculum for the MRs prepares the newly recruited science graduates for generating enough prescriptions by catering to the identified needs and demands of the physicians expressed or otherwise, and thus grab higher market-share for the companies they represent. Approaches such as inducements, persuasion, emotional blackmail, serving family members, etc. are used. The type, quantity and quality of inducements offered to the physicians depend upon his/her capacity to produce prescriptions. The popular physicians are cultivated meticulously by the MRs to establish brand loyalty and fulfill individual and company targets. The physicians, willingly or unwillingly, become part of the system with few exceptions. Neither the regulatory authority nor the professional or consumer rights bodies has any role to control or ractify the process.ConclusionsThe aggressive marketing of the pharmaceutical companies compel their MRs, programmed to maximize market share, to adopt unethical means if and when necessary. When medicines are prescribed and dispensed more for financial interests than for needs of the patients, it reflects system’s failed ability to hold individuals and entities accountable for adhering to basic professional ethics, code of conduct, and statutory laws.

End-of-life medical decision making presents a major challenge to patients and physicians alike. In order to determine whether it is ethically justifiable to forgo medical treatment in such scenarios, clinical data must be interpreted alongside patient values, as well as in light of the physician's ethical commitments. Though much has been written about this ethical issue from religious perspectives , little work has been done from an Islamic point of view. To fill the gap in the literature around Islamic bioethical (...) perspectives on the matter, we derive a theologically rooted rubric for goals of care. We use the Islamic obligation for Muslims to seek medical treatment as the foundation for determining the clinical conditions under which Muslim physicians have a duty to treat. We next link the theological concept of accountability before God to quality-of-life assessment. Using this construct, we suggest that a Muslim physician is not obligated to maintain or conti..

Social capital and scaling social impact are two of the most important concepts within social entrepreneurship and social enterprise research. However, what role social capital plays in scaling social impact is less understood and academic literatures on the connection of these two crucial concepts are fragmented and scattered. To fill this research gap, we have conducted a bibliometric review to inform academics and researchers the salient agents in the field and categorize the conceptual structure of the knowledge base. Using science (...) mapping techniques, we have analyzed 1549 relevant documents from SCOPUS that are published between 1986 and 2021. The primary objective of this review is to uncover the size, growth trajectory, and geographic distribution of literatures related to social capital's role in scaling social impact. Additionally, we have also analyzed key publishing journals, authors, and documents to map the intellectual structure and research fronts of the domain. The review shows that there is a reasonable accumulation of scientific knowledge concerning social capital's role in scaling social impact in the last three decades. Another key finding is that, some of the keywords identified within the research fronts are closely aligned with a number of UN-SDG goals. This is the first study to systematically map social capital's role in scaling social impact literature with the help of a science mapping tool called bibliometric analysis. This work provides a clear overview of the evolution of the research field and presents potentially important research gaps that require further attention. (shrink)

This paper examines the concept of manifestation process in Kashmir Shaivism from Shiva tattva to Prithvi tattva and their transcendental and immanent predicates (Prakrti and Purusa).This paper also shows that the ultimate reality, Paramshiva, manifests itself into various forms which likely represent the theory of causation. This research paper also provides answer to two questions; First, how ultimate reality with its thirty-six principles or elements manifest in various forms and what types of forms ‘Descent’ attains from the ‘universal self’? Second, (...) how manifestation process takes place from the ‘cosmic self’ (universal consciousness) to a ‘limited self’ (Jiva)? Since, this paper is based on philosophical exploration of manifestation process and contains interpretation and argumentation of Pratyabhijna philosophy only; it excludes manifestation due to Yogas (Upayas) and Karmas. Moreover, it explains the Trika form of reality (Shiva/God, Shakti/World, and Nara/Man) and also the identity between ‘ascent’ and ‘descent’. Manifestation further investigates the union of Shiva and Shakti with Maya and displays its character (Prakashvimarshmaya). This work further tries to describe the contribution of Abhinavagupta in the concept of manifestation. (shrink)
