This investigation delves into the rationale behind the preferential applicability of the non-Newtonian nanofluid model over alternative frameworks, particularly those incorporating porous medium considerations. The study focuses on analyzing the mass and heat transfer characteristics inherent in the Williamson nanofluid’s non-Newtonian flow over a stretched sheet, accounting for influences such as chemical reactions, viscous dissipation, magnetic field and slip velocity. Emphasis is placed on scenarios where the properties of the Williamson nanofluid, including thermal conductivity and viscosity, exhibit temperature-dependent variations.

Following the use of the OHAM approach, an analytical resolution to the proposed issue is provided. The findings are elucidated through the construction of graphical representations, illustrating the impact of diverse physical parameters on temperature, velocity and concentration profiles.

Remarkably, it is discerned that the magnetic field, viscous dissipation phenomena and slip velocity assumption significantly influence the heat and mass transmission processes. Numerical and theoretical outcomes exhibit a noteworthy level of qualitative concurrence, underscoring the robustness and reliability of the non-Newtonian nanofluid model in capturing the intricacies of the studied phenomena.

Available studies show that no work on the Williamson model is conducted by considering viscous dissipation and the MHD effect past over an exponentially stretched porous sheet. This contribution fills this gap.

This chapter aims to develop an institutionalist concept of faith based on Williamson's concept of ‘institutional trust’ and Coleman's contribution to ‘placement of trust’. As a starting point, it considers the social capital literature on trust from the perspective of institutional economics and economic anthropology. ‘Institutional faith’ posits as a normative state the inevitability of trust with regard to certain questions human beings cannot answer. This has a behaviour-channelling effect which makes, e.g. for institutional stability. The proposed concept is evaluated critically by contrasting it with T. Kuran's concept of ‘preference falsification’ in the Hindu caste system. Finally, the concept is challenged by today's Hindu fundamentalism and makes a differentiation between fundamentalism and institutional faith.

Williamson's systematic treatment of transaction costs in explaining governance structures has rarely been applied to the field of environmental economics. The aim of this chapter is to address this oversight by analysing how transaction cost economics can help choose among environmental policy tools.

We apply the analytical framework of discrete structural alternatives – market, hybrid forms and hierarchy – to the choice of environmental policy instruments. Environmental-related transactions, which differ in their attributes, are aligned with categories of policy instruments, which differ in their cost and competence, so as to effect a discriminating – mainly transaction costs economizing – result.

First, we suggest defining the transaction as the trading of property rights to the use of natural resources. Second, the characteristics of the transaction are described as mainly measurement costs. Third, we determine the conditions under which a particular ‘governance structure’ that is a policy instrument is chosen.

A major contribution of our analysis is to question the relevance of many economists’ prescription in favour of incentive-based instruments. Indeed, in some plausible circumstances a command-and-control instrument may be more efficient by economizing on transaction costs.

Environmental economics has employed the seminal contribution of Ronald H. Coase (1960) intensively but has remained relatively unaffected by the contributions of perhaps his most influential follower, Oliver E. Williamson. Our chapter is a first step towards an operationalization à la Williamson of Coase's (1992, p. 778) ‘fundamental insights’ in the environmental realm.

Since Bram Stoker’s tale of Count Dracula struck a chord with a sensation-hungry public, vampires have remained a popular part of horror in cinema. Since the turn of the millennium, vampires have now become a mainstay of horror TV. Programmes like True Blood (2008–2014) and The Vampire Diaries (2009–2017) have propelled the vampire into the home.

This chapter will investigate the problematic, but often sympathetic relationship between vampires and humans in The Vampire Diaries.

Some understanding and form of inter‐organisation management is necessary and desirable if a channel is to maintain or achieve satisfactory performance as a competitive entity (Stern and El‐Ansary 1992). Although this view is not novel (of. Alderson 1954,1957), it has not been the subject of extensive research (Frazier 1983), and interorganisational coordination in distribution channels has perhaps received less focus as a survival requirement (Dwyer and Oh 1988) than it deserves. Stern and El‐Ansary (1992) seem to reflect traditional points of view when stating that power is the major means available to achieve coordination and co‐operation among channel members. Power, however, gives rise to channel dependence and interdependence issues, (of. Pfeffer and Salancik 1978; Gaski 1984; Brown, Lusch and Muehling 1983), and issues of interorganisational governance mechanisms which for some years have also interested institutional economists, (of. Williamson 1993, 1991, 1986, 1981, 1975, Ouchi 1980) and economic sociologists, (of. Granovetter, 1985, Granovetter and Swedberg 1992). The marketing literature (of. Heide and John 1992; 1990; 1988) has questioned Williamson's somewhat simplistic treatment of opportunism as an underlying behavioural norm, central as this is to his transaction cost paradigm. Since Heide and John's [1992] work on the role of norms in marketing relationships, there is a distinct possibility that insufficient further research has been done in order to allow comparisons of their findings with those of other studies that differ with regard to cultures, settings, and time periods. Maintaining focus on the transaction between dyadic exchange partners as a fundamental activity in marketing channels (of. Achrol, Stern, and Reve 1983), the objectives of this article are to examine the existence or otherwise of relational norms between dyadic exchange partners serving as a governance mechanism safeguarding against opportunistic behaviour in the presence of transaction‐specific assets. The work of Heide and John [1992] shed much light on this, but examined the dyad from the perspective of a strong buyer facing a large number of small suppliers. We will focus on a strong supplier, facing a large number of small buyers, currently, but not indefinitely, bound to it by legislation and contract. The perspective adopted will be that of many small buyers (phar‐macies) from a monopolistic ethical drug wholesaler, at the time of dismantling of a statutory wholesale drug monopoly in Norway.

Through a case study on the governance structures of the UN, the purpose of this paper is to develop a critique of Public and Private Bureaucracies Transaction Cost Economics (PPBTCE) (Williamson, 1999) as a theoretical lens to analyze internal oversight structures.

The authors explore “probity” and “independence” transactions’ attributes through historical narrative case-based research to answer the question – Why did numerous attempts to strengthen the governance of UN internal oversight structures not relieve “probity” hazards?

The analysis shows that at the UN increasing and strengthening the governance of oversight structures, i.e., incentives, did not relieve probity/ethics hazards as predicted in PPBTCE. Secretaries-General and UN General Assembly, entities charged with oversight powers, systematically trumpeted the UN Charter, breaching probity/ethics and disregarding the supervisory independence prerogative of internal oversight structures, hence failing to contribute to the “common good” and to protect the UN mission.

This paper is the first application of PPBTCE to internal oversight transactions within an International organization context testing probity and independence attributes. The authors find that “independence” outweighs the “asset specificity” attribute whenever decisions on the governance of internal oversight arise. As far as sourcing decisions are concerned, the authority of the sovereign and the independence of the judiciary as well as quasi-judiciary transactions are not transferable attributes and, thus, cannot be contracted along with the actors’ ethics. PPBTCE should be modified to include, e.g. “virtues ethics” behavioral assumption as a transaction costs’ reduction device and explanatory framework for “probity” hazards, abandoning the opportunism behavioral assumption.

Post‐industrial predictions of a rapid growth in new technology homeworking have gained widespread currency to become part of the conventional wisdom. However the evidence, including primary research material, suggests that the claims for new technology homeworking, both regarding its extent and its alleged benefits, have been considerably overestimated. In particular, new technology homeworking by itself does not appear to open up opportunities for women to improve their position in the labour market; the demographic changes predicted for the 1990s may provide a better bet. Nevertheless, there is a danger in assuming that all firms apply the same strategy when employing homeworkers; at least three different variations can be identified and this has important implications for personnel managers. The overestimation of new technology homeworking stands in stark contrast to traditional homeworking where the extent has been considerably underestimated. This marginalisation of traditional homeworking stems in large part from the distortion caused by the conceptual split between private and public realms. The failure to find evidence to support the growth of new technology homeworking leads to a consideration of how the arguments may better be considered as rhetoric designed to advance a certain set of ideas – in particular that set associated with “privatisation” as a political ideology.

The purpose of this viewpoint article is to acquaint those engaged in health care quality improvement and patient safety programs with an effective, well‐documented but overlooked method. As described in a 1978 article, “Achievable Benefit Not Achieved” (ABNA) is a formal, efficient, transdisciplinary, evidence‐based method to identify and prioritize quality improvement project topics.

Narrative review of personal experience and pertinent literature.

While the ABNA method succeeds in serving its purpose when applied, and no evidence could be found to discredit it, ABNA appears to have been abandoned and forgotten for reasons of political expediency.

A strength and weakness of this research is its reliance upon personal narratives from the limited number of individuals still available who have first‐hand knowledge of past events. Convergence of those narratives along common themes, and their consistency with published records, is reassuring; however, age, memory, and some reluctance to broach political barriers limit one's ability to examine key events of past decades. A structured interview format conducted by a trained and experienced interviewer who had no vested interests in the topic, plus independent analysis of transcripts by researchers who have experience in qualitative methods, protects internal validity of the work.

Today's emphasis on continuously improving the quality and safety of health care requires appropriately focused, effective programs. ABNA arose and was suppressed in an era when health service deficiencies characteristically remained hidden as potential embarrassments rather than sought out as opportunities for improvement. ABNA, that era's under‐appreciated tool, should be reconsidered for its unique merits to guide today's programs.

This work, one of the first efforts to trace the entire history of ABNA, confirms that the method remains practical, effective and has not been discredited.

The purpose of this paper is to consider heat and mass transfer on magnetohydrodynamics (MHD) Williamson fluid flow over a slendering stretching sheet with variable thickness in the presence of radiation and chemical reaction. All pertinent flow parameters are discussed and their influence on the hydrodynamics, thermal and concentration boundary layer are presented with the aid of the diagram.

The governing partial differential equations are reduced into a system of ordinary differential equations with the help of suitable similarity variables. A discrete version of the homotopy analysis method (HAM) called the spectral homotopy analysis method (SHAM) was used to solve the transformed equations. SHAM is efficient, and it converges faster than the HAM. The SHAM provides flexibility when solving linear ordinary differential equations with the use of the Chebyshev spectral collocation method.

The findings revealed that an increase in the variable thermal conductivity hike the temperature and the thermal boundary layer thickness, whereas the reverse is the case for velocity close to the wall.

The uniqueness of this paper is the exploration of combined effects of heat and mass transfer on MHD Williamson fluid flow over a slendering stretching sheet. The Williamson fluid term in the momentum equation is expressed as a linear function and the viscosity and thermal conductivity are considered to vary in the boundary layer.
