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.

This article focuses on the hegemonic shift portrayed by Ayn Rand in Atlas Shrugged. The book focuses on the conflict between producers and those who exploit them. The protagonist, John Galt, leads a strike of the producers, which undermines the society's looters and puts an end to the hegemonic control of the left. Neoliberalism—used here as a synonym for contemporary libertarian thought—rescues the world from the havoc wreaked by statism. This shift is studied in the light of Antonio Gramsci's theory (...) of hegemony, focusing on the role of intellectuals. (shrink)

Academic performance is among the several components of academic success. Many factors, including socioeconomic status, student temperament and motivation, peer and parental support influence academic performance. Our study aims to investigate the determinants of academic performance with emphasis on the role of parental styles in adolescent students in Peshawar Pakistan. A total of 456 students from 4 public and 4 private schools were interviewed. Academic performance was assessed based on self-reported grades in the latest internal examinations. Parenting styles were assessed (...) through the administration of the Parental bonding instrument. Regression analysis was conducted to assess the influence of socio-demographic factors and parenting styles on academic performance. Factors associated with and differences between “care” and “overprotection” scores of fathers and mothers were analyzed. Higher socio-economic status, father’s education level and higher care scores were independently associated with better academic performance in adolescent students. Affectionless control was the most common parenting style for fathers and mothers. When adapted by the father, it was also the only parenting style independently improving academic performance. Overall, mean “care” scores were higher for mothers and mean “overprotection” scores were higher for fathers. Parenting workshops and school activities emphasizing the involvement of mothers and fathers in the parenting of adolescent students might have a positive influence on their academic performance. Affectionless control may be associated with improved academics but the emotional and psychosocial effects of this style of parenting need to be investigated before recommendations are made.

Pakistan is a developing country and it has been showed remarkable development in many areas since its foundation in 1947. However, still some issues have not been handled properly, like poverty, corruption, load shedding, water crises etc. Apart from other issues, poverty is a big issue of the country and it can be observed more or less in every province. In this paper, we have analyzed the ground situation of district Ghotki, through surveys, which is considered last district of Sindh. (...) We tried to find the problems of poor people of district Ghotki, observed their general life style, discussed their issues and inquired about government’s role to provide the people with basic necessities of life. In this paper, mainly qualitative method is adopted to reach to best conclusion. However, partially quantitative style could also be observed, especially where concepts of Microfinance are discussed. We realized that around 40% people of the district need microfinance services and they are ready to welcome Islamic Microfinance banks, because people don’t want to opt interest based conventional microfinance services, and secondly, conventional microfinance banks don’t have capacity to cover vast area of the district.

To determine the attitude of general practitioners towards continuing medical education and reasons motivating or hindering them from attending CME procedures, we conducted a cross-sectional survey from November 2013 to April 2014 in Karachi. Three hundred general practitioners who possessed a medical license for practice in Pakistan filled a pre-designed questionnaire consisting of questions pertaining to attitudes towards CME. Data was entered and analyzed using SPSS v16.0. 70.3% of the participants were males. Mean age was 47.75 ± 9.47 years. Only (...) 67.33% knew about CME and only 52% had attended a CME session. Reasons for attending CME procedures reported were: need for updating knowledge, skills and competencies, opportunity to meet colleagues and presenting scientific papers. Mean Likert score was 1.67 for those who thought CME is worthwhile and 1.44 for those who consider their clinical duties as the major hurdle in attending CME procedures. Most common cause for not attending CME was lack of knowledge followed by time constraint. Most physicians were not sufficiently informed about the potential benefits of CME and had never attended a CME session. Most common reason for attending CME procedures reported was need for updating knowledge, skills and competencies while reasons hindering physicians from attending CME were lack of knowledge and time constraint.

Young academics have been facing a problem of high turnover rate due to missing links between the institutions’ policies and the performance. This study explores the effect of job embeddedness and community embeddedness on creative work performance and intentions to leave of young teaching staff in academic institutions in Pakistan. In this study, 300 qualified young academics from public and private universities were selected as subjects and asked to complete a questionnaire. Data were collected via mail-survey. A variance-based structural equation (...) model is employed to measure the path model. The results show that the fit-dimension of organizational- and community-embeddedness, along with the moderating effect of organization size and the availability of nearby alternative jobs have a significant impact on improving perceived creative performance and reducing staff turnover intentions. This study suggests that organizations should focus on organizational-fit and community-fit constructs in their nurturing strategies to embed young teachers in their academic institutions. This study also suggests that monetary rewards only are relatively ineffective to improve retention. Hence, public and private sector universities should facilitate meaningful contributions from young teachers in creative work and provide opportunities for social interactions and personal development.

Errors have been the concern of providers and consumers of health care services. However, consumers' perception of medical errors in developing countries is rarely explored. The aim of this study is to assess community members' perceptions about medical errors and to analyse the factors affecting this perception in one Middle East country, Oman.

The paper proposes a research model explaining the sequential mediation effect of job embeddedness and work engagement between ethical leadership and career satisfaction. The model also examines whether JE heightens WENG, a factor indirectly influenced by ethical practices ending in employee satisfaction. The study used a time-lagged data collection procedure and survey responses of 247 hotel workers in China. Data were analyzed through structural equation modeling. The results showed that EL directly and indirectly contributes to employee CS. The present empirical (...) framework extends the hospitality industry literature by explaining the precise mechanism through which EL generates CS among hospitality workers in China. The paper offers theoretical and practical implications and future research directions. (shrink)

Unmanned aerial vehicles, particularly quadcopters, have several medical, agriculture, surveillance, and security applications. However, the use of this innovative technology for civilian applications is still very limited in low-income countries due to the high cost, whereas low-cost controllers available in the market are often tuned using the hit and trial approach and are limited for specific applications. This paper addresses this issue and presents a novel proof of concept low-cost quadcopter UAV design approach using a systematic Model-Based Design method for (...) mathematical modeling, simulation, real-time testing, and prototyping. The quadcopter dynamic model is developed, and controllers are designed using Proportional Integral, and Derivative, Pole Placement, and Linear Quadratic Regulator control strategies. The stability of the controllers is also checked using Lyapunov stability analysis. For verification and validation of the design, Software-in-the-Loop, Processor-in-the-Loop, Hardware-in-the-loop testing, and Rapid Control Prototyping have been performed. The V&V methods of the MBD approach showed practically valid results with a stable flight of the quadcopter prototype. The proposed low-cost POC quadcopter design approach can be easily modified to have enhanced features, and quadcopters with different design parameters can be assembled using this approach for a diverse range of applications.

_In 1497, Syed Muhammad Jaunpuri of India claimed to be a reformer with the mission to purify Islam by justifying his claim according to the teachings and sayings of the Prophet of Islam. He started by curbing the innovations, focusing on belief in Allah, offering prayers, search for God and the truth, and also challenging the religious scholars of his time. Thus, he was criticized by religious scholars by refuting Jaunpuri’s claim of being a reformer, interestingly, academicians have also (...) ignored Jaunpuri’s role as a reformer, but this paper discusses the life of Jaunpuri by focusing on his role as a reformer in India, moreover, this paper limits its scope with the life of Jaunpuri as a reformer. The research used a descriptive cum analytical approach which was aimed at making the research a qualitative one and for that various libraries of Pakistan and personal collections of followers of Jaunpuri were accessed, and at the same time, various websites were also surveyed. So, the research resolved that Jaunpuri was a reformer of the 15 th century India who did his best to reform the people and society of his time by bringing them closer to their Creator._. (shrink)

This paper explores the ‘indigenous’ philosophy of education of Syed Muhammad Naquib al-Attas, a Malay-Muslim scholar who’s theoretical work culminated in the establishment of a counter-colonial higher education institution. Through presenting al-Attas’ life and philosophy and by exploring the arguments of his critics, I aim to shed light on the challenges and paradoxes faced by indigenous academics working at the interface of philosophy and education.

Although researchers have paid much attention to the journey metaphor (e.g., Forceville, 2006a, 2011a, 2011b; Forceville & Jeulink, 2011), little seems known about its role for moral political cognition. Using data from the US and UK public discourses on the Euro crisis as an example, this paper draws on Lakoff’s (1996) Moral Politics Theory, demonstrating that the journey metaphor can play a crucial role for political cognition, and especially for moral political judgment.

The research on the dark side of leadership is still in its infancy. We have contributed to this line of research by proposing that work alienation acts as an underlying mechanism through which aversive leadership results in reduced job performance. We further propose that psychological capital acts as an important personal resource that reduces the negative effects of aversive leadership in the form of work alienation. The proposed model gets its support from the conversation of resources theory given by Hobfoll (...) (1981) which suggests that stressful situation like an aversive leadership results in the loss of employee resources as a result of that he/she indulges in work alienation and shows poor job performance to retain back the lost resources. People with better personal resources in the form of psychological capital are better able to cope-up with the aversive leader behavior and make them able to avoid work alienation. It is a time-lagged study. The data for the current study was collected from 321 employees working in the service sector organizations, particularly universities, banks and telecom organizations, through personally administered questionnaires. The results supported the mediation and moderation hypothesis. Limitations and future research along with theoretical and practical implications are given at the end. (shrink)

In recent years, there has been an escalation in cases of cyber violence, which has had a chilling effect on users' behavior toward social media sites. This article explores the causes behind cyber violence and provides empirical data for developing means for effective prevention. Using elements of the stimulus–organism–response theory, we constructed a model of cyber-violence behavior. A closed-ended questionnaire was administered to collect data through an online survey, which results in 531 valid responses. A proposed model was tested using (...) partial least squares structural equation modeling using SmartPLS 3.0, v. Research findings show that information inequality is a strong external stimulus with a significant positive impact on digital distrust and negative emotion. However, the effects of information overload on digital distrust and the adverse effects of communication overload on negative emotions should not be ignored. Both digital distrust and negative emotions have significant positive impacts on cyber violence and cumulatively represent 11.5% changes in cyber violence. Furthermore, information overload, communication overload, information inequality, and digital distrust show a 27.1% change in negative emotions. This study also presents evidence for competitive mediation of digital distrust by information overload, information inequality, and cyber violence. The results of this study have implications for individual practitioners and scholars, for organizations, and at the governmental level regarding cyber-violence behavior. To test our hypotheses, we have constructed an empirical, multidimensional model, including the role of specific mediators in creating relationships. (shrink)

The question of whether females tend to act more ethically or risk-averse compared to males is an interesting ethical puzzle. Using a large sample of US firms over the 1992–2014 period, we investigate the effect that the gender of a chief executive officer has on earnings management using classification shifting. We find that the pre-Sarbanes–Oxley Act period was characterized by high levels of classification shifting by both female and male CEOs, but the magnitude of such practices is, surprisingly, significantly higher (...) in firms with female CEOs than in those with male CEOs. By contrast, our results suggest that following the passage of the punitive SOX Act, classification shifting by female CEOs declined significantly, whilst it remained pervasive in firms with male CEOs. This suggests that the observable differences in financial reporting behavior between male and female CEOs seem to be because female CEOs are more risk-averse, but not necessarily more ethically sensitive than their male counterparts are. The central tenets of our findings remain unchanged after several additional checks, including controlling for alternative earnings management techniques, corporate governance mechanisms, CEO and chief financial officer characteristics and propensity score-matching.

The proposed work describes an approach for the segmentation of abnormal lung CT scans of COVID-19. Lung diseases are the leading killer in both men and women. The pulmonary experts normally make attempts, such as early detection of patients by tomography tests before lung specialists treat patients who are tortured by lung disease. Moreover, lung specialists do their best to detect the presence of lung conditions. X rays or CT scan checks are performed for tomography tests. The finest approach for (...) medical diagnosis and a wide range of uses is computed tomography. This kind of imaging offers elaborate cross-sectional pictures of skinny slices of the organic structure. However, the preprocessing and denoising methods of Lung CT scans may mask some important image features. To address this challenge, we propose a novel framework involving an optimization technique algorithm to solve a multilevel thresholding problem based on information theory to segment abnormal lung CT scans. The proposed framework will evaluate a sample of CT scan images taken from a well-known benchmark database. The evaluation results will assess subjectively and objectively to demonstrate the effectiveness of the proposed framework. (shrink)

How is a philosophical tradition created? What role does literary biography play in the formation of intellectual reception history? Through a detailed analysis of the lives and works of post-Avicennan philosophers, this monograph traces the intellectual history and development of the Avicennan tradition from the fifth/eleventh to the eighth/fourteenth century. Section 1 investigates the genres of Arabo-Islamic biobibliographical and prosopographical writings as a source for the history of Arabic philosophy, delineating their literary topoi, the construction of philosophical authority, and the (...) relationship of Sunnī and Twelver-Šīī Islam to Aristotelian logic and philosophy.

The number of edges in a shortest walk from one vertex to another vertex of a connected graph G is known as the distance between them. For a vertex x and an edge e = a b in G, the minimum number from distances of x with a and b is said to be the distance between x and e. A vertex x is said to distinguish two distinct edges e 1 and e 2 if the distance between x and (...) e 1 is different from the distance between x and e 2. A set X of vertices in a connected graph G is an edge metric generator for G if every two edges of G are distinguished by some vertex in X. The number of vertices in such a smallest set X is known as the edge metric dimension of G. In this article, we solve the edge metric dimension problem for certain classes of planar graphs. (shrink)

Taking support from ego-depletion theory, this study examines ego depletion as a mechanism that explains how employees’ organizational citizenship behavior leads to antagonistic consequences, i.e., service sabotage.

There is a considerable scholarly discussion regarding how Islamic values influence CSR, but prior studies remain fragmented and scattered across several fields. This paper, therefore, aims to offer a more comprehensive understanding of the impacts of Islamic values on CSR by conducting a systematic literature review of 84 relevant publications from 1995 through 2020. The results of a thematic analysis show that there are four underlying themes to consider when explaining the influence of Islamic values on CSR: (1) Islamic narratives (...) promoting CSR, (2) Islam-based CSR, (3) Islamic financial institutions as enablers of CSR, and (4) stakeholders’ perspectives on how Islamic values influence CSR. This study contributes to the CSR literature by providing a systematic understanding of how Islamic values influence CSR and by identifying current challenges and promising directions for future exploration along this line of inquiry.

Data analytics, machine intelligence, and other cognitive algorithms have been employed in predicting various types of diseases in health care. The revolution of artificial neural networks in the medical discipline emerged for data-driven applications, particularly in the healthcare domain. It ranges from diagnosis of various diseases, medical image processing, decision support system, and disease prediction. The intention of conducting the research is to ascertain the impact of parameters on diabetes data to predict whether a particular patient has a disease or (...) not. This paper develops an improved ANN model trained using an artificial backpropagation scaled conjugate gradient neural network algorithm to predict diabetes effectively. For validating the performance of the proposed model, we conduct a large set of experiments on a Pima Indian Diabetes dataset using accuracy and mean squared error as evaluation metrics. We use different number of neurons in the hidden layer, ranging from 5 to 50, to train the ANN models. The experimental results show that the ABP-SCGNN model, containing 20 neurons, attains 93% accuracy on the validation set, which is higher than using the other ANNs models. This result confirms the model’s effectiveness and efficiency in predicting diabetes disease from the required data attributes. (shrink)

The aim of this study is to explore social media marketing activities and their impact on consumer intentions. This study also analyzes the mediating roles of social identification and satisfaction. The participants in this study were experienced users of two social media platforms Facebook and Instagram in Pakistan. A self-administered questionnaire was used to collect data from respondents. We used an online community to invite Facebook and Instagram users to complete the questionnaire in the designated online questionnaire system.

Furthermore, social identification mediates the relationship between social media activities and satisfaction, and satisfaction mediates the relationship between social media activities and the intentions of users. This will help marketers how to attract customers to develop their intentions. This is the first novel study that used SMMAs to address the user intentions with the role of social identification and satisfaction in the context of Pakistan. (shrink)

Good’s theorem is the apparent platitude that it is always rational to ‘look before you leap’: to gather information before making a decision when doing so is free.

Soon after the first COVID-19 positive case was detected in Wuhan, China, the virus spread around the globe, and in no time, it was declared as a global pandemic by the WHO. Testing, which is the first step in identifying and diagnosing COVID-19, became the first need of the masses. Therefore, testing kits for COVID-19 were manufactured for efficiently detecting COVID-19. However, due to limited resources in the densely populated countries, testing capacity even after a year is still a limiting (...) factor for COVID-19 diagnosis on a larger scale and contributes to a lag in disease tracking and containment. Due to this reason, we started this study to provide a better cost-effective solution for enhancing the testing capacity so that the maximum number of people could get tested for COVID-19. For this purpose, we utilized the approach of artificial neural networks (ANN) to acquire the relevant data on COVID-19 and its testing. The data were analyzed by using Machine Learning, and probabilistic algorithms were applied to obtain a statistically proven solution for COVID-19 testing. The results obtained through ANN indicated that sample pooling is not only an effective way but also regarded as a “Gold standard” for testing samples when the prevalence of the disease is low in the population and the chances of getting a positive result are less. We further demonstrated through algorithms that pooling samples from 16 individuals is better than pooling samples of 8 individuals when there is a high likelihood of getting negative test results. These findings provide ground to the fact that if sample pooling will be employed on a larger scale, testing capacity will be considerably increased within limited available resources without compromising the test specificity. It will provide healthcare units and enterprises with solutions through scientifically proven algorithms, thus, saving a considerable amount of time and finances. This will eventually help in containing the spread of the pandemic in densely populated areas including vulnerably confined groups, such as nursing homes, hospitals, cruise ships, and military ships.

This article investigates the nexus between bank-specific risks and the financial stability of the banks for a panel data set of 15 scheduled banks in Pakistan over a 12-year period from 2009 to 2020. Using the fixed-effect model, the study result shows that bank-specific risks, i.e., credit risk and liquidity risk are detrimental to bank stability, whereas funding risk has no significant impact on bank stability. Besides these, bank size has also a negative impact on bank stability, whereas the return (...) on assets revealed a positive influence. To ensure stability, bank management should establish policies that confirm secure loan granting and timely reimbursement from customers to minimize the credit risk. Besides this, management should keenly observe the liquidity position and should also effectively mobilize the customer deposits to attain financial stability. (shrink)

Stability analysis based on Lyapunov–Krasovskii functional and the stability of the closed-loop system is guaranteed. Using the LMI technique, we obtain triggered parameters. To demonstrate the feasibility (...) and usefulness of the suggested methodology, two examples are shown. (shrink)

This article investigates the origin of editorial images, with a focus on the mental processes that enable cartoonists and illustrators across cultures to come up with novel ideas. It provides the most compelling evidence to date that recycling, where artists regularly recycle pictorial and compositional ideas they have developed earlier, is the origin of ideas. Recycling theory is thus compatible with a variety of ongoing research programs. Among these are Turner’s work on blending (2014), Musolff’s research on scenarios (2016), Langacker’s (...) ideas on constructional schemas (1991), Johnson’s work on image schemas (1987), and van Dijk’s proposals concerning discourse complexes and intertextuality (2014). More specifically, the present study gives cognitively plausible answers to the perennial questions: To what extent does recycling shape and constrain the human way of thinking? Is it bound to certain cultural traditions? Does it characterize the style of certain artists or artistic movements? How does it contribute to discourse? Are the products of recycling always imaginative and creative? Is it a mode of efficiency? The theoretical insights are applied to 440 editorial images of Egyptian and British origin. This investigation will aid both semiotics scholarship and cognition studies based on multimodal stimuli. (shrink)

Vaccination is an important tool for handling healthcare programs both in developed and developing countries. The current global scenario calls for a more‐efficacious, acceptable, cost‐effective and reliable method of immunization for many fatal diseases. It is hoped that the adoption of oral vaccines will help to provide an effective vaccination strategy, especially in developing countries. Mucosal immunity generated by oral vaccines can serve as a strong first line of defense against most of the pathogens infecting through the mucosal lining. Advances (...) in elucidating the mechanism of action of oral vaccines will facilitate the design of more effective, new generation vaccines. There are promising developments in the use of different agents to effectively deliver the vaccine candidate. It is hoped that ongoing research may be able to set another cardinal point, after polio vaccine, in eradicating infectious diseases. BioEssays 29:591–604, 2007. © 2007 Wiley Periodicals, Inc.
