The 2019 Pandemic has forced students to take online classes, increasing their stress levels and negatively impacting their academic performance. This issue urges the development of a mechanism to make online learning more effective in this nerve-racking time. Therefore, the present study has integrated the task technology fit model and the DeLone and McLean Model of Information Systems Success to address the stated issue. The data were collected from 330 and 326 students of top-ranked public and private universities of Punjab, (...) respectively. The theoretical framework was analyzed with the help of structural equation modeling using Analysis of Moment Structures. The findings indicate that overall quality positively predicts performance through the mediating role of user satisfaction and TTF. The overall quality also positively elevates performance through the mediating role of user satisfaction and actual usage of the system. Moreover, perceived usefulness proved to be a moderator between overall quality and user satisfaction. Finally, the expected practical and theoretical implications have also been discussed. (shrink)

Software defects prediction at the initial period of the software development life cycle remains a critical and important assignment. Defect prediction and correctness leads to the assurance of the quality of software systems and has remained integral to study in the previous years. The quick forecast of imperfect or defective modules in software development can serve the development squad to use the existing assets competently and effectively to provide remarkable software products in a given short timeline. Hitherto, several researchers have (...) industrialized defect prediction models by utilizing statistical and machine learning techniques that are operative and effective approaches to pinpoint the defective modules. Tree family machine learning techniques are well-thought-out to be one of the finest and ordinarily used supervised learning methods. In this study, different tree family machine learning techniques are employed for software defect prediction using ten benchmark datasets. These techniques include Credal Decision Tree, Cost-Sensitive Decision Forest, Decision Stump, Forest by Penalizing Attributes, Hoeffding Tree, Decision Tree, Logistic Model Tree, Random Forest, Random Tree, and REP-Tree. Performance of each technique is evaluated using different measures, i.e., mean absolute error, relative absolute error, root mean squared error, root relative squared error, specificity, precision, recall, F-measure, G-measure, Matthew’s correlation coefficient, and accuracy. The overall outcomes of this paper suggested RF technique by producing best results in terms of reducing error rates as well as increasing accuracy on five datasets, i.e., AR3, PC1, PC2, PC3, and PC4. The average accuracy achieved by RF is 90.2238%. The comprehensive outcomes of this study can be used as a reference point for other researchers. Any assertion concerning the enhancement in prediction through any new model, technique, or framework can be benchmarked and verified. (shrink)

Excessive use of social media is a developing concern in the twenty-first century. This issue needs to be addressed before it has any more significant consequences than what we are currently experiencing. As a preventive technique, advertisements and awareness-raising campaigns about the detrimental impact of digital technologies are used. The application of novel mathematical techniques and terminologies in this field of study will have significant potential to enhance healthy living by preventing certain ailments. This is the most compelling justification for (...) conducting a new study with the most up-to-date techniques at our disposal. This study investigates clear and concise transmission in order to generate a deterministic mathematical model of social media addiction S M A using the fractal-fractional derivative operator. Also, the analysis of the S M A model in terms of the invariant domain, the existence of a positive invariant solution, and equilibria assumptions are stated in a detailed manner. Besides that, the basic reproduction number ℝ 0 < 1 is computed, demonstrating that the proposed methodology is more efficacious. The Atangana-Baleanu FF differential operators are recently defined in FF differential operators that are applied to characterize the S M A model’s mathematical algorithm. We investigated the numerical behaviour of the S M A in three ways: changing the fractional-order α as well as the fractal-dimension ℘ ; changing α while keeping ℘ constant; and changing ℘ while keeping α constant. Our examined visualizations and simulation studies using MATLAB for the numerical modelling of the aforementioned system showed that the novel developed Atangana-Baleanu FF differential operators produce remarkable results when compared to the classical frame.

In this article, we investigated a deterministic model of pneumonia-meningitis coinfection. Employing the Atangana–Baleanu fractional derivative operator in the Caputo framework, we analyze a seven-component approach based on ordinary differential equations. Furthermore, the invariant domain, disease-free as well as endemic equilibria, and the validity of the model’s potential results are all investigated. According to controller design evaluation and modelling, the modulation technique devised is effective in diminishing the proportion of incidences in various compartments. A fundamental reproducing value is generated by (...) exploiting the next generation matrix to assess the properties of the equilibrium. The system’s reliability is further evaluated. Sensitivity analysis is used to classify the impact of each component on the spread or prevention of illness. Using simulation studies, the impacts of providing therapy have been determined. Additionally, modelling the appropriate configuration demonstrated that lowering the fractional order from 1 necessitates a rapid initiation of the specified control technique at the largest intensity achievable and retaining it for the bulk of the pandemic’s duration.

The article is an introduction to the use of the principle of falsification in economic science. It is shown what difficulties the named criterion of demarcation encounters when trying to introduce it into humanitarian knowledge. The specificity of economic knowledge itself, which makes it difficult to use the principle of falsification, is explicated.

Hardy is the last of the Victorian and one of the most popular novelists of England. He, being an author of unique endowments, was not much esteemed in his life time. Hardy became the victim of stereotypical criticism and was badly ostracized by the ecclesiastical circles and the critics of his time as they merely focused on the depressing features of his fiction. This paper intends to reveal certain aspects of his work which remained neglected for a long time. The (...) present study is designed to focus on those characteristics of his work which win the title of a modern novelist for him. Hardy was quite conscious of the shifting environment around him at the vogue of industrialization that left profound marks on his meditative temperament. His depiction of the 19th century scenario is dominated with clash and collision between innovation and tradition. His art deals with twofold aspects of modernity exposing the sanguine and gloomy consequences of modernity. Owing to such an approach of the writer he is regarded as a social realist and one of the earliest of the modern novelists. Hardy poignantly observes the pathetic condition of the labourers, on one hand, and the modern mechanical advancements, one the other, which were of little benefit for the common man in society. The current study is designed to focus upon his approach to the modern developments in the broad context of social and political changes. Hardy is a modern novelist as he concentrates on the current issues such as gender, class, social and psychological disorders, etc. He is a supporter of class and female liberation. (shrink)

The regression model is generally utilized in several fields of study because of its applications. Regression is an extremely incredible approach; it builds up a connection between dependent and independent variables. We have addressed a powerful computational model by utilizing dengue information joined with fuzzy multiple linear regression. Information is accumulated on dengue fever through the survey. This paper is centered on the comparison of the crisp method with fuzzy multiple linear regression, and then, the utilization of a fuzzy multiple (...) regression method is explained after the comparison. We have used multiple regression and then converted the said technique into three fuzzy cases. The effectiveness of the fuzzy multiple regression model is measured by numerical computation and comparison of both techniques. 2020 Mathematics Subject Classification.

Information of high evidentiary quality plays a crucial role in forensic investigations. Research shows that information provided by witnesses and victims often provide major leads to an inquiry. As such, statements should be obtained in the shortest possible time following an incident. However, this is not achieved in many incidents due to demands on resources. This intersectional study examined the effectiveness of a chatbot (the AICI), that uses artificial intelligence (AI) and a cognitive interview (CI) to help record statements following (...) an incident. After viewing a sexual harassment video, the present study tested recall accuracy in participants using AICI compared to other tools (i.e., Free Recall, CI Questionnaire, and CI Basic Chatbot). Measuring correct items (including descriptive items) and incorrect items (errors and confabulations), it was found that the AI CI elicited more accurate information than the other tools. The implications on society include AI CI provides an alternative means of effectively and efficiently recording high-quality evidential statements from victims and witnesses. (shrink)

We survey the meta-ethical tools and institutional processes that traditional Islamic ethicists apply when deliberating on bioethical issues. We present a typology of these methodological elements, giving particular attention to the meta-ethical techniques and devices that traditional Islamic ethicists employ in the absence of decisive or univocal authoritative texts or in the absence of established transmitted cases. In describing how traditional Islamic ethicists work, we demonstrate that these experts possess a variety of discursive tools. We find that the ethical responsa—i.e., (...) the products of the application of the tools that we describe—are generally characterized by internal consistency. We also conclude that Islamic ethical reasoning on bioethical issues, while clearly scripture-based, is also characterized by strong consequentialist elements and possesses clear principles-based characteristics. The paper contributes to the study of bioethics by familiarizing non-specialists in Islamic ethics with the role, scope, and applicability of key Islamic ethical concepts, such as “aims” (maqāṣid), “universals” (kulliyyāt), “interest” (maṣlaḥa), “maxims” (qawā`id), “controls” (ḍawābit), “differentiators” (furūq), “preponderization” (tarjīḥ), and “extension” (tafrī`).

The coastal zone of Bangladesh is endowed with dynamic ‘Terrestrial’ and ‘Coastal and Marine ecosystem’. The zone confronts with declined environmental quality owing to unethical anthropogenic interventions. Few studies regarding ethical attitudes of local communities to conserve the coast were conducted earlier. Two objectives, such as (i) heavy metal concentration, and (ii) physio-chemical quality of sample soil and water were selected to reveal the environmental state of study area. Five heavy metals like- Cadmium, Copper, Iron, Lead, and Zinc; and four (...) physio-chemical parameters such as, the pH, Electrical Conductivity, Temperature, and Turbidity of sample soil and water were measured. The average concentration of Pb in soil is 10 times higher than world average (0.03 mg/g), while Cd concentration in soil is two times more than world average (0.11 mg/L). The concentration of Fe at Inani beach water is 1.54 mg/g more than world average (3.4 mg/g). The physio-chemical parameters are within standard range. Unethical discharge of toxic effluents from shrimp hatcheries, and municipal garbage are main sources of pollution, which ensue into environmental degradations. Concentration of five heavy metals and Calcium Carbonate (CaCO3) in sample mollusk shells exhibit biodiversity deterioration. The mollusk shells from Inani beach contains 0.04 mg/L Cd,0.08 mg/L Cu, 0.42 mg/L Fe, 0.38 mg/L Pb, and 0.07 mg/L Zn. The CaCO3 content in mollusk shells at Inani beach is 49.5%, which indicates the degradation of the mollusks, as shells normally are made with 95% - 97% Calcium Carbonate. Hence, the Department of Environment (DOE), Bangladesh (GoB) declared the area as an ‘Ecologically Critical Area’ (ECA). The concerned stakeholders, like- CPP volunteers and officials, Forest Division, Fisheries Research Institute, Bangladesh Water Development Board, Union Chairman and Journalists of Cox’s Bazar recommended insertion of moral values among local stakeholders through trainings, motivational lectures, demonstrations and dramas, as well as, incorporation of lessons about consequences of unethical activities upon geo-environment into text books. Though least practice has been found regarding moral values during survey, the present research advocates in developing ‘Knowledge pool’ about coastal environment, creating awareness, and developing moral ethics among the local, regional and national stakeholders.

The debate in acknowledging street harassment as an existing social problem renders research necessary on the topic. Street harassment is said to occur when it takes place in a public setting and is initiated by a stranger. Through this correlation research, we aimed to establish the relationship between experiencing street harassment and fear of victimization. A positive correlation between the experience of street harassment and fear of victimization was hypothesized and a positive correlation between street harassment and negative reaction to (...) harassment was also hypothesized. Additionally, the most recurring type of public harassing behaviors was identified as well. Two self report questionnaires were administered; A gender based harassment scale assessing the frequency of 8 harassing behaviors which ranged on a likert scale from 0 to 4 and a modified version of The Fear of Crime survey measuring fear of victimization. These questionnaires were administered to a sample of 250 females recruited via convenient sampling technique that had experienced street harassment previously. Percentages, mode and Pearson’s Product correlation were used to statistically analyze data. Results showed a significant, weak positive correlation between street harassment and fear of victimization and a moderate positive correlation between experiencing street harassment and negative reaction towards harassment. The most frequent harassing behavior was being stared in a manner that made the victims uncomfortable with 98% of participants experiencing it, followed by 83.5% of the participants experiencing non-verbal sounds. Through this research, we were able to conclude street harassment does have negative implications for women. (shrink)

The purpose of this research is to examine the influence of servant leadership on teachers of moral education degree programs in Pakistan. By utilizing social learning, we propose that servant leadership and perceived coworker support can reduce the knowledge hiding by enhancing the sense of organization-based psychological ownership. The findings of time-lagged and multi-source data indicate that servant leadership has a negative relationship with knowledge hiding. Our results also indicate that psychological ownership mediates the effects of servant leadership on knowledge (...) hiding. Moreover, a higher level of perceived coworker support enhances the sense of psychological ownership which helps to reduce knowledge hiding. This research extends strong support for the proposition that servant leaders who adopt an employee-centered management approach, stressing personal integrity and care for employees significantly affect employee attitudes and behaviors. Moreover, this study suggests that managers should demonstrate care toward their subordinates which helps them to reduce negative behaviors. (shrink)

This paper interprets John von Neumann's views on the proper role of mathematics in science, with attention to its implications for economics. The evolution of von Neumann's thought over his lifespan, an examination of which is greatly aided by some self-conscious appraisals of von Neumann himself, suggests that von Neumann ended by taking a very pragmatic approach to the use of mathematics. One can almost characterize it as an engineering approach to the philosophy of mathematics since von Neumann takes mathematics (...) to be justified by its applications. This approach, which is surprisingly non-technical and hence accessible to general readers, is then placed in the context of his wider world-view. (shrink)

The high prevalence of aggression, anxiety and stress symptoms among team members in the organisation, while acquisition of task is alarming causation of adjustment disorder influences on team embeddedness, is the subject of this study.

We strongly feel that there is a need to reexamine organisational team credentials and possible strong influences on individual’s psychosocial adjustment disorders. Findings suggest psychosocial adjustment factors are significantly correlated with psychosocial disorders (PSDs). (shrink)

From Antiquity until recently, philosophers and mathematicians have continually discussed the concept of angle and its relation to archimedean and non-archimedean theories of measurement. For the first time, this book traces the history of these discussions in Greek and Arabic, from Euclid to Kamāl al-Dīn al-Fārisī, after whom the discussion was not resumed until Newton and Euler. The volume presents first editions of over twenty texts, either in Arabic or Greek and translated into Arabic, of the greatest mathematicians and philosophers (...) of the time. The texts are here translated into French and supplemented with extensive commentary. The book begins with the definitions and propositions of Euclid on angles and measurement, followed by the Greek commentary tradition represented by Proclus and Simplicius (only extant in Arabic) and the writings of the Arabic mathematicians and philosophers from the 9th through 14th century, placing the fundamental contributions by Avicenna and Ibn al-Haytham into their historical context and showing how numerous successors produced new syntheses of their work.

Present study compared disturbed eating attitudes among male and female university students. For which it as postulated that female university students would have more disturbed eating attitudes as compare to male students. For that reason 200 males and 200 female university students from various universities of Karachi were incorporated in the study. Their age ranged from 19 to 25. Participants after verbal and written covenantfrom the heads of their institution were asked to fill the respondents’ profile form to gather the (...) participant’s demographic information, followed by Eating Attitude Test which was used to know ones disturbed eating ways. For statistical evaluation t-test was applied, which specified that male university students experience more disturbed eating attitudes compare to female learners. This clears that distressed eating attempts are not limited to females, but is now affecting males as well. Thus to avert its budding prevalence, teaching institutions should supervise its amassed risks in their students and stimulate them to healthy lines of eating. (shrink)

Applying the resolution–scale relativity principle to develop a mechanics of non-differentiable dynamical paths, we find that, in one dimension, stationary motion corresponds to an Itô process driven by the solutions of a Riccati equation. We verify that the corresponding Fokker–Planck equation is solved for a probability density corresponding to the squared modulus of the solution of the Schrödinger equation for the same problem. Inspired by the treatment of the one-dimensional case, we identify a generalization to time dependent problems in any (...) number of dimensions. The Itô process is then driven by a function which is identified as establishing the link between non-differentiable dynamics and standard quantum mechanics. This is the basis for the scale relativistic interpretation of standard quantum mechanics and, in the case of applications to chaotic systems, it leads us to identify quantum-like states as characterizing the entire system rather than the motion of its individual constituents.

The (...) results have implications for rethinking board composition requirements in the emerging markets. [PUBLICATION ABSTRACT]. (shrink)

BackgroundIn this study, medical errors are defined as unintentional patient harm caused by a doctor’s mistake. This topic, due to limited research, is poorly understood in Malaysia. The objective of this study was to determine the proportion of doctors intending to disclose medical errors, and their attitudes/perception pertaining to medical errors.MethodsThis cross-sectional study was conducted at a tertiary public hospital from July- December 2015 among 276 randomly selected doctors. Data was collected using a standardized and validated self-administered questionnaire intending to (...) measure disclosure and attitudes/perceptions. The scale had four vignettes in total two medical and two surgical. Each vignette consisted of five questions and each question measured the disclosure. Disclosure was categorised as “No Disclosure”, “Partial Disclosure” or “Full Disclosure”. Data was keyed in and analysed using STATA v 13.0.ResultsOnly 10.1% intended to disclose medical errors. Most respondents felt that they possessed an attitude/perception of adequately disclosing errors to patients. There was a statistically significant difference when comparing the intention of disclosure with perceived disclosures. Most respondents were in common agreement that disclosing an error would make them less likely to get sued, that minor errors should be reported and that they experienced relief from disclosing errors.ConclusionMost doctors in this study would not disclose medical errors although they perceived that the errors were serious and felt responsible for it. Poor disclosure could be due the fear of litigations and improper mechanisms/procedures available for disclosure. (shrink)

Social interactions through social commerce platforms empower consumers to share their personal experiences with others, but its role becomes more significant for societal protection during COVID-19. Numerous scholars have studied e-commerce extensively, but there is a lack of studies to identify social commerce characteristics to attract potential consumers during COVID-19. This study aims to examine the role of social commerce constructs by integrating social presence as a moderator in the model to explain consumers online shopping intentions in a Pakistani context, (...) where lack of trust on the reliability and validity of comments from other consumers being considered the growing concern toward the success of social commerce.

Sustainability is concerned with the impact of present actions on the ecosystems, societies, and environments of the future. Such concerns should be reflected in the strategic planning of sustainable corporations. Strategic intentions of this nature are operationalized through the adoption of a long-term focus and a more inclusive set of responsibilities focusing on ethical practices, employees, environment, and customers. A central hypothesis, that we test in this paper is that companies which attend to this set of responsibilities under the term (...) superior sustainable practices, have higher financial performance compared to those that do not engage in such practices. The target population of this study consists of the top 100 sustainable global companies in 2008 which have been selected from a universe of 3,000 firms from the developed countries and emerging markets. We find significant higher mean sales growth, return on assets, profit before taxation, and cash flows from operations in some activity sectors of the sample companies compared to the control companies over the period of 2006–2010. Furthermore, our findings show that the higher financial performance of sustainable companies has increased and been sustained over the sample. Notwithstanding sample limitation, causal evidence reported in this paper suggests that, there is bi-directional relationship between corporate social responsibilities practices and corporate financial performance.

BackgroundCOVID-19 break out has created panic and fear in society. A strict kind of lockdown was imposed in Wuhan, Hubei province of China. During home confinement due to lockdown, people face multidimensional issues. The present study explored the psychological impacts of COVID-19 home confinement during the lockdown period and Wuhan’s residents’ attitude toward physical activity.MethodsA cross-sectional online survey was conducted to collect the primary data according to the study objectives. The population was Wuhan residents who were in home confinement. A (...) total of 2280 participant’s reply to the online questionnaire survey and collected data after quantifying the data, about 2200 ; about female, about male, others about, and about were not disclosed their gender participants responses were used for analysis. The collected data were analyzed through appropriate statistical techniques.ResultsAccording to results, H1 is supported with β = −40.793, t = 57.835, p = 0.000, which claimed a negative association between COVID-19 lockdown policy and behavior and attitude. Results for H2 reveals that the COVID-19 lockdown policy have negative influence on emotional control with β = −0.769, t = 46.766, p = 0.000 and it is supported. H3 documented a significant positive relationship between COVID-19 lockdown policy and lockdown period psychological impact, which means lockdown policy, is the main reason to increase the lockdown psychological impact. Further, COVID-19 lockdown policy have negative influence on physical activity and self-belief with β = −0.657, t = 32.766, p = 0.000 and β = −0.620, t = −6.766, p = 0.000 respectively. H6 stated that there is a positive impact of behavior and attitude toward physical activity. The results for H6, behavior, and attitude affecting the physical activity with β = 0.401, t = 10, p = 0.000, which is supported.ConclusionCOVID-19 home confinement created various psychological impacts, negatively affecting the emotional state due to depression and anxiety. Physical activity is the best strategy to manage human nature’s psychological issues, and people’s attitudes were positive toward physical activity during home confinement. However, the lockdown policy also affects physical activity participation negatively, and a sedentary lifestyle prevailed during home confinement. (shrink)

Artificial Immune Systems (AIS) are intelligent algorithms derived on the principles inspired by human immune system. In this research work, electroencephalography (EEG) signals for four distinct motor movement of human limbs are detected and classified using Negative Selection Classification Algorithm (NSCA). For this study, a widely studied open source EEG signal database (BCI IV - Graz dataset 2a, comprising 9 subjects) has been used. Mel Frequency Cepstral Coefficients (MFCCs) are extracted as selected feature from recorded EEG signals. Dimensionality reduction of (...) data is carried out by applying two hidden layered stacked auto-encoder. Genetic Algorithm (GA) optimized detectors (Artificial Lymphocytes) are trained using Negative Selection Algorithm (NSA) for detection and classification of four motor movements. The trained detectors consist of four sets of detectors, each set is trained for detection and classification of one of the four movements from the other three movements. The optimized radius of detector is small enough not to mis-detect the sample. Euclidean distance of each detector with every training dataset sample is taken and compared with optimized radius of detector as a non-self detector. Our proposed approach achieved a mean classification accuracy of 86.39% for limb movements over 9 subjects with a maximum individual subject classification accuracy of 97.5 % for subject number eight.

In lieu of an abstract, here is a brief excerpt of the content:DAVID HUME AND EIGHTEENTH CENTURY MONETARY THOUGHT: A CRITICAL COMMENT ON RECENT VIEWS To the argument that it makes little difference what precise roles were played by various actors in a great movement, and that the busy modern reader cannot be bothered to go behind the scenes of popular successes, the answer is simple: it is on the whole better to call men and events by their right names; (...) it is on the whole wiser not to make false diagrams of the way things happen. What, after all, are we so busy about? Jacques Barzun, Darwin, Marx, Wagner The praise that has been bestowed upon David Hume's monetary thought in recent years would suggest that however little attention is paid to the history of economic thought otherwise, no one is averse to a long and respectable lineage.1 However, it is just when an individual is singled out and focused upon that the most misleading ideas can arise; furthermore, when the scholars who provide this attention are renowned authorities in specialized fields, their views receive very widespread circulation. It would not be easy to find a contemporary student of the eighteenth century who would assert that the mercantilists believed real wealth to consist of gold and silver, yet the late Harry Johnson made just such an assertion not very long ago, and the number of economists who read Harry Johnson must far outnumber those who read eighteenthcentury scholars.2 By the same token, the liberal praise bestowed upon those credited with having "demolished" mercantilism, such as David Hume, requires careful scrutiny. A recent article by Dietrich Fausten3 has shown how different Hume's analysis 157 actually was from modern monetarism, despite the many attempts to designate Hume the father of monetarist doctrines, and this critical approach can be taken farther. Before turning to an examination of Hume's position, it may be worthwhile to make a methodological point. There are those who consider delving into indebtedness and priorities "antiquarian" (but not if their own contributions are in question!). After all, they claim, Hume's views are there in black and white, he wrote elegantly and his philosophical merits are widely admired; does it really matter if Hume did not acknowledge his sources, that he was somewhat inconsistent, or that he caricatured his opponents? Surely some compassion is appropriate for someone who wrote at the very dawn of "economic science." This is to miss the point of such historical scrutiny altogether. If compassion were required, why should it be bestowed upon Hume, rather than on such predecessors as Gervaise, Cantillon or Vanderlint? Scholars employ certain critical standards in judging published work; let us employ these standards to Hume and if sympathy be required, let it follow and not precede the analysis. II The following passage is certainly one of the most frequently quoted in the history of economics but its importance for our argument makes repetition necessary. Suppose, that all the money of Great Britain were multiplied fivefold in a night, must not the contrary effect follow? Must not all labour and commodities rise to such an exorbitant height, that no neighbouring nations could afford to buy from us; while 158 their commodities, on the other hand, became comparatively so cheap, that, in spite of all the laws which could be formed, they would be run in upon us, and our money flow out; till we fall to a level with foreigners, and lose that great superiority of riches, which had laid us under such disadvantages?4 Two points should be noted about the above. First, Hume assumes a sudden, large inflow of money to make his point. This is a very different thing from the small [relative to the money stock] and steady inflow advocated by the so-called mercantilists. Secondly, Hume assumes that this sudden inflow is met by instantaneous adjustment in prices. Otherwise, if the change in, say, wages attracts more labour, there is no reason why the increased money supply could not lead to a greater output and thus avoid inflation. International labour mobility was a standard feature of mercantilist thought and so it will be seen that Hume's "new" result is obtained by his... (shrink)

A recent article by Dietrich Fausten3 has shown how different Hume's analysis 157 actually was from modern monetarism, despite the many attempts to designate Hume the father of monetarist doctrines, and this critical approach can be taken farther. Before turning to an examination of Hume's position, it may be worthwhile to make a methodological point. There are those who consider delving into indebtedness and priorities "antiquarian" (but not if their own contributions are in question!). After all, they claim, Hume's views are there in black and white, he wrote elegantly and his philosophical merits are widely admired; does it really matter if Hume did not acknowledge his sources, that he was somewhat inconsistent, or that he caricatured his opponents? Surely some compassion is appropriate for someone who wrote at the very dawn of "economic science." This is to miss the point of such historical scrutiny altogether. If compassion were required, why should it be bestowed upon Hume, rather than on such predecessors as Gervaise, Cantillon or Vanderlint? Scholars employ certain critical standards in judging published work; let us employ these standards to Hume and if sympathy be required, let it follow and not precede the analysis. II The following passage is certainly one of the most frequently quoted in the history of economics but its importance for our argument makes repetition necessary. Suppose, that all the money of Great Britain were multiplied fivefold in a night, must not the contrary effect follow? Must not all labour and commodities rise to such an exorbitant height, that no neighbouring nations could afford to buy from us; while 158 their commodities, on the other hand, became comparatively so cheap, that, in spite of all the laws which could be formed, they would be run in upon us, and our money flow out; till we fall to a level with foreigners, and lose that great superiority of riches, which had laid us under such disadvantages?4 Two points should be noted about the above. First, Hume assumes a sudden, large inflow of money to make his point. This is a very different thing from the small [relative to the money stock] and steady inflow advocated by the so-called mercantilists. Secondly, Hume assumes that this sudden inflow is met by instantaneous adjustment in prices. Otherwise, if the change in, say, wages attracts more labour, there is no reason why the increased money supply could not lead to a greater output and thus avoid inflation. International labour mobility was a standard feature of mercantilist thought and so it will be seen that Hume's "new" result is obtained by his... (shrink)

How do we see the world? What is the way of looking at the world? In other words, how do we explain the problems of our life and the world we live in? This is what philosophy does, i.e., philosophy is a way of explaining life and the world. More precisely, philosophy is an outlook of the fundamental problems of life and the world. A philosopher starts his thinking with the exercise of rationality. He makes a rational investigation of the (...) problems with which he is concerned. In this sense, philosophy is a rational outlook of the fundamental problems of life and the world. A philosopher is a rational and critical thinker and in this way of thinking he formulates his ideas and builds theories about life and the world. In this sense, philosophy is mainly a theoretical activity and a philosopher is concerned with conceptual or theoretical activity. This is the traditional way of defining philosophy.

This study examines the influence of managerial ownership on firm agency costs among listed firms in Bangladesh. This is an institutional setting that features a mixture of agency costs. This institutional setting has a concentration of ownership by managers, but the firms are not solely owned by managers. The extant literature suggests that the sacrifice of wealth by the principal and potential costs associated with monitoring the agents is known as the agency cost. This study uses three measures of agency (...) cost: the ‘expense ratio’, the ‘Q-free cash flow interaction’, and the ‘asset utilisation ratio’. The finding of the study is that managerial ownership reduces the firm agency cost only under the ‘asset utilisation ratio’ measure of agency cost; this is robust with regard to a number of robustness tests. Furthermore, the non-linearity tests suggest that the convergence of interest is evident with very high and low levels of managerial ownership. The entrenchment effect by the owners is evident at moderate levels of managerial ownership. Although there has been great scepticism among management researchers on the validity of agency theory, overall, the findings of this study do not reject the validity of agency theory. Given that the entrenchment by managers is evident at certain levels of ownership and that the agency problem may still exist between insiders and outsiders, legislative guidelines for controlling share ownership may be required.
