Collecting data using an appropriate sampling technique is a challenging task for a researcher to do. The researchers will be unable to collect data from all possible situations, which will preclude them from answering the study’s research questions in their current form. In light of the enormous number and variety of sampling techniques/methods available, the researcher must be knowledgeable about the differences to select the most appropriate sampling technique/method for the specific study under consideration. In this context, this study also (...) looks into the basic concepts in probability sampling, kinds of probability sampling techniques with their advantages and disadvantages. Social science researchers will benefit from this study since it will assist them in choosing the most suitable probability sampling technique for completing their research smoothly and successfully.

Using Least Square Residual Minimization techniques, this paper develops an optimal reserve model, known as the OPREM model, which is essential in optimizing the costs of reserve holding. The paper also sets-out to test and compare the relative predictions of economic trends of the OPREM model as well as the predictions of alternative models in literature. Establishing the predictive accuracy of economic trends of these models are crucial for the gradual and cost-effective accumulation of reserves. The research concludes that, the (...) decision to optimize the cost of reserves under a stable currency environment is reliant on the gold impact factor and not on inflation or interest rates. We also found on further analysis of the OPREM that the OPREM model is better positioned to eliminate the procyclicality and perverse rush in reserve build-ups experienced in developing and emerging countries by effectively setting the reserve stock against economic trends. The research fixes the optimal reserves around a benchmark of 0.7–1.2 of previous year's optimal value. However, in the absence of past optimal values, a benchmark between 2 and 6 times of average inflows for short-term analysis or analysis with small data observations. However, for long-term analysis or analysis with large data frequency, the reserve stock should be fixed on a benchmark of 2–9 times of the average inflows. (shrink)

Manipulation of physical models such as tangrams and tiles is a popular approach to teaching early mathematics concepts. This pedagogical approach is extended by new computational media, where mathematical entities such as equations and vectors can be virtually manipulated. The cognitive and neural mechanisms supporting such manipulation-based learning—particularly how actions generate new internal structures that support problem-solving—are not understood. We develop a model of the way manipulations generate internal traces embedding actions, and how these action-traces recombine during problem-solving. This model (...) is based on a study of two groups of sixth-grade students solving area problems. Before problem-solving, one group manipulated a tangram, the other group answered a descriptive test. Eye-movement trajectories during problem-solving were different between the groups. A second study showed that this difference required the tangram's geometrical structure, just manipulation was not enough. We propose a theoretical model accounting for these results, and discuss its implications. (shrink)

This paper extends the discussion of business ethics by examining the issue of corruption, its definition, the solutions being proposed for dealing with it, and the ethical perspectives underpinning these proposals. The paper’s findings are based on a review of association, think-tank, and academic reports, books, and papers dealing with the topic of corruption, as well as the pronouncements, websites, and position papers of a number of important global organizations active in the fight. These organizations include the World Bank, the (...) International Monetary Fund, the Organization for Economic Co-operation and Development, Transparency International, USAID, the United Nations, the International Chamber of Commerce, the Organization of American States, and the Council of Europe. Our discussion departs from prior analyses by adopting a Foucaultian theoretical framing and by incorporating insights found in the virtue ethics literature. Implications are provided for international business organizations. (shrink)

This paper presents a framework for the design of human-centric identity management systems. Whilst many identity systems over the past few years have been labelled as _human-centred,_ we argue that the term has been appropriated by technologists to claim moral superiority of their products, and by system owners who confuse administrative convenience with benefits for users. The framework for human-centred identity presented here identifies a set of design properties that can impact the lived experience of the individuals whose identity is (...) being managed. These properties were identified through an analysis of public response to 15 historic national identity systems. They capture the practical design aspects of an identity system, from structural aspects that affect the flow of information - _Control Points, Subject Engagement, Identity Exposure, Population Coverage_—to the metrical aspects that considers how information is used and perceived—_Expert Interpretation, Population Comprehension, Information Accuracy, Information Stability, Subject Coupling, Information Polymorphism_. Any identity system can be described in terms of these fundamental properties, which affect individuals’ lived experience, and therefore help to determine the acceptance or rejection of such systems. We first apply each individual property within the context of two national identity systems—the UK DNA Database and the Austrian Citizen Card, and then also demonstrate the applicability of the framework within the contexts of two non-government identity platforms—Facebook and Phorm. Practitioners and researchers would make use of this framework by analysing an identity system in terms of the various properties, and the interactions between these properties within the context of use, thus allowing for the development of the potential impacts that the system has on the lived experience.

The attainment of good governance is the question of the day in Bangladesh. This paper discusses the , parliamentary accountability, and assesses the effectiveness of the Bangladesh Parliament in ensuring governmental accountability and promoting good governance since 1991 when the country re-entered into parliamentary democracy. Considerable discrepancies between the expected role and practical performances are identified and the study further identified a number of problems that severely hinder parliament's accountability function. This paper primarily argues that Bangladesh vested excessive powers in (...) the hands of the executive branch; it, therefore, lacks the proper checks and balances a strong parliament could provide.

This work has aimed to investigate the consumers’ green product purchase attitudes and behavioral intention during COVID-19 pandemic. Data was collected through a survey method of 503 consumers in Malaysia. Data were analyzed using the partial least square method. The findings revealed that fear of COVID-19 pandemic has a significant impact on green product behavioral intention. Green product literacy, green product orientation, and social influence have a significant influence on green product purchase attitudes. The results also indicated that consumers’ green (...) product purchase attitudes mediate the effect of green product literacy, green product orientation, and social influence on behavioral intention. The findings of this work will provide strategically relevant references to green marketers and retail managers in the understanding of consumers’ green product purchase attitudes and green product behavioral intention during the ongoing uncertainty of the COVID-19 pandemic.

The current study examines the micro-linguistic details of Twitter responses to the whistleblower-initiated publication of the Panama Papers. The leaked documents contained the micro-details of tax avoidance, tax evasion, and wealth accumulation schemes used by business elites, politicians, and government bureaucrats. The public release of the documents on April 4, 2016 resulted in a groundswell of Twitter and other social media activity throughout the world, including 161,036 Spanish-language tweets in the subsequent 5-month period. The findings illustrate that the responses were (...) polyvocal, consisting a collection of overlapping speech genres with varied thematic topics and linguistic styles, as well as differing degrees of calls for action and varying amounts of illocutionary force. The analysis also illustrates that, while the illocutionary force of tweets is somewhat associated with the adoption of a prosaic and vernacular ethical stance as well as with demands for action, these types of voicing behaviors were not present in the majority of the tweets. These results suggest that, while social media platforms are a popular site for collective forms of voicing activities, it is less certain that these collective stakeholder voices necessarily result in forceful accountability demands that spill out of the communication medium and thus serve as an impulse for positive social change.

This study examines the 3.5 m+ English-language original tweets that occurred during the 2011 Occupy Wall Street protests. Starting from previous research, we analyze how character terms such as “the banker,” “politician,” “the teaparty,” “GOP,” and “the corporation,” as well as concept terms such as “ethics,” “fairness,” “morals,” “justice,” and “democracy” were used by individual participants to respond to the Occupy Wall Street events. These character and concept terms not only allowed individuals to take an ethical stance but also accumulated (...) into a citizen’s narrative about social accountability. The analysis illustrates how the centrality of the different concepts and characters in the conversation changed over time as well as how the concepts ethics, morals, fairness, justice, and democracy participated within the conversation, helping to amplify the ethical attributes of different characters. These findings contribute to our understanding of how demands for social accountability are articulated and change over time. (shrink)
