Abstract

Purpose

The purpose of this paper is to address various works on mixed convection and proposes 10 unified models (Models 1–10) based on various thermal and kinematic conditions of the boundary walls, thermal conditions and/ or kinematics of objects embedded in the cavities and kinematics of external flow field through the ventilation ports. Experimental works on mixed convection have also been addressed.

Design/methodology/approach

This review is based on 10 unified models on mixed convection within cavities. Models 1–5 involve mixed convection based on the movement of single or double walls subjected to various temperature boundary conditions. Model 6 elucidates mixed convection due to the movement of single or double walls of cavities containing discrete heaters at the stationary wall(s). Model 7A focuses mixed convection based on the movement of wall(s) for cavities containing stationary solid obstacles (hot or cold or adiabatic) whereas Model 7B elucidates mixed convection based on the rotation of solid cylinders (hot or conductive or adiabatic) within the cavities enclosed by stationary or moving wall(s). Model 8 is based on mixed convection due to the flow of air through ventilation ports of cavities (with or without adiabatic baffles) subjected to hot and adiabatic walls. Models 9 and 10 elucidate mixed convection due to flow of air through ventilation ports of cavities involving discrete heaters and/or solid obstacles (conductive or hot) at various locations within cavities.

Findings

Mixed convection plays an important role for various processes based on convection pattern and heat transfer rate. An important dimensionless number, Richardson number (Ri) identifies various convection regimes (forced, mixed and natural convection). Generalized models also depict the role of “aiding” and “opposing” flow and combination of both on mixed convection processes. Aiding flow (interaction of buoyancy and inertial forces in the same direction) may result in the augmentation of the heat transfer rate whereas opposing flow (interaction of buoyancy and inertial forces in the opposite directions) may result in decrease of the heat transfer rate. Works involving fluid media, porous media and nanofluids (with magnetohydrodynamics) have been highlighted. Various numerical and experimental works on mixed convection have been elucidated. Flow and thermal maps associated with the heat transfer rate for a few representative cases of unified models [Models 1–10] have been elucidated involving specific dimensionless numbers.

Originality/value

This review paper will provide guidelines for optimal design/operation involving mixed convection processing applications.

Abstract

Purpose

The purpose of this paper is to investigate the firm’s role in the value creation process. In particular, after categorizing the activities that firms carry out to facilitate the creation of value, the “value space,” an actionable framework within which different dimensions of value creation are integrated, is developed and discussed.

Design/methodology/approach

The framework is built up on process theory, an in-depth review of the literature and a multiple case study carried out on 65 European firms in the furniture industry.

Findings

The value space is both a practical and theoretically based framework which contributes to the development of a more holistic and “actionable” view on the role of firm in the value creation process; also it provides managers with a tool to support the analysis, management and innovation of the value creation process.

Originality/value

The systematic categorization of firms’ activities and their subsequent integration into a value creation framework are a missing piece in terms of understanding the value creation process carried out by firms. Also, by facilitating the analysis and innovation of the value creation process, the framework can be used to support both exploitative and explorative business process management.

Abstract

Purpose

This paper aims to study the Integrated Criminal Justice System; the law enforcement carried out by the Indonesian National Police is expected to be able to realize legal values, namely, legal justice, expediency and certainty.

Design/methodology/approach

This research can broadly be grouped into the realm of the socio-legal research approach. The domain of law enforcement in corruption cases is related to the preliminary investigation and full investigation process. The research location chosen is at Indonesian National Police Headquarter (Mabes Polri) and Greater Jakarta Metropolitan Regional Police. The main data sources are stakeholders who are related and have the authority as preliminary phase investigators and full phase investigators. The next informants are determined by snowball technique, which consists of several informants as follows: Director of Special Criminal Investigation Directorate of Greater Jakarta Metropolitan Regional Police, head of Corruption Crime Sub-Directorate of Greater Jakarta Metropolitan Regional Police, investigators of Corruption Crime Sub-Directorate of Special Criminal Investigation Directorate of Greater Jakarta Metropolitan Regional Police, members of Commission III of the Indonesian House of Representatives (DPR), constitutional law experts and police experts. The data in this research are obtained through observation activities, visual interviews, document interpretation (text) and material and personal experience.

Findings

The corruption cases handled by the Indonesian National Police have mostly come from information reports from the public. Based on the information report from the community, the preliminary investigation phase is carried out by the preliminary phase investigator of the Indonesian National Police in the field. In addition, a preliminary investigation and full investigation is carried out due to the results of an audit from the BPK or BPKP. Preliminary investigation and full investigation begin after it is alleged that a criminal act of corruption had occurred based on the report, complaints and information received by the preliminary phase investigator or full phase investigator from the community. In conducting the preliminary investigation and full investigation of corruption cases, based on the results of the research conducted, it is also found that the Indonesian National Police’s preliminary phase investigator and full phase investigator experience several obstacles, besides supporting factors that support the success of a preliminary investigation and full investigation.

Originality/value

This research is a case study in which no previous studies have used the same method in Greater Jakarta Metropolitan Regional Police (Polda Metro Jaya). This paper is the result of the researcher’s research on what is described above, guided by the constructivism paradigm, the researcher applies the paradigmatic analysis to understand how the preliminary investigation and full investigation on corruption crimes by Greater Jakarta Metropolitan Regional Police act as part of an integrated criminal justice system. Through the paradigmatic analysis, the researcher then reveals how while upholding the law, the Indonesian National Police actually sought to realize legal justice, expediency and certainty.

Abstract

Purpose

Off-premise restaurant service has a new addition – food delivery robots. This new technology and off-premise service, in general, has received little research attention, despite continued year-over-year sales growth for both carry-out and delivery. Therefore, this study aims to analyze off-premise service modes, including food delivery robots, for service quality gaps between consumer expectations and actual performance and among the various modes.

Design/methodology/approach

Performance of three off-premise restaurant service modes (robot-delivery, human-delivery and carry-out) were evaluated using a mixed-methods approach. Consumer expectations were ascertained about food- and service-related performance factors using a survey, and a field observation study was conducted to obtain actual performance data for these factors. Findings from both approaches were compared to identify gaps and differences.

Findings

For food-related performance, consumers reported lower expectations for food safety and food quality from robot- and human-delivered food; however, no differences were observed among the three modes in the field study. Consumers also expected lower service-related performance from robot-delivery for service efficiency and ease of use (than human-delivery and carry-out) and monetary value (than carry-out). Consumers deemed robots the most sustainable and human-delivery the most convenient compared to other modes – however, not all service-related expectations aligned with actual performances.

Originality/value

This study was the first to comparatively examine off-premise restaurant service. Identification of a missing link in service gap analysis was among the theoretical contributions of this study. Managerially, this study provides previously unavailable insights into opportunities for improvement for off-premise service and use of delivery robots.

Abstract

Purpose

The purpose of this paper is to enhance understanding of social reproduction by investigating the financial management practices carried out by the consumers. Using depth interviews, a theoretical model is developed to describe how financial management practices are carried out to facilitate the attainment of class‐specific life goals and discuss how these practices are related to social reproduction.

Design/methodology/approach

In total, 22 adults aged 22‐79 were interviewed face‐to‐face. They were asked to describe their financial management practices and their perception and feelings towards their financial situation. They were also asked about the life goals and their perception of progress towards achieving the stated goals.

Findings

Different sets of financial management practices and their corresponding structural implications are identified in this study. The coping practices are the ones the working class carry out to meet mundane financial obligations, leaving little for long‐term strategizing. The balancing practices are the ones the middle class carry out to juggle hectic family lives and promising careers. With a low level of slack resources, the middle class need to make monetary trade‐off in their practices. The achieving practices are the ones that are practiced by the upper‐middle class who settle in their class position and focus on furthering the growth of self and family. The structural implications of financial management practices make the attainment of occupational status via education least accessible for the working class, but within easy reach for the upper‐middle class.

Research limitations/implications

The paper studies a convenient sample of adults in a mid‐Western city in the USA, which has a high level of racial homogeneity (i.e. White) compared with the metropolitans in the USA. Nevertheless, this study communicates the social embeddedness and structural ramifications of individual/household financial management practices.

Originality/value

This is the first study to examine how class situation, with its various resource levels and differences in time horizon, influences the enactment of financial management practices, and how these micro‐processes give rise to social reproduction.

Abstract

With the aim of discovering the important factors in training staff to use newly installed automated circulation systems, the appropriate libraries in New Zealand were sent a questionnaire in 1988. This asked how libraries had trained their staff, and the outcome of the training in terms of satisfaction with their decisions, sparseness of mistakes after implementation and time taken for staff to attain efficiency after implementation. The most important factors in training were that the vendor should be heavily involved in organizing and carrying out training; training should be given before the system went live; staff should be given detailed training in the whole system; and a number of different training methods should be used. These factors were especially important for libraries installing their first automated system, those installing integrated systems, those with few staff, and those installing their systems in the earlier years of automation; that is, those libraries whose staff have the least background in the system being installed, have the greatest need for excellent training.

Abstract

Purpose

The objective of sustainability assurance (SA) is to give credibility to nonfinancial information (Cheng et al., 2015). In France, certain companies are subject by regulation to the implementation of SA in particular with the transposition of European Directive 2014/95/EU into national law. SA mission is a process by which an independent third-party organization (ITO) assures companies' nonfinancial information. Although this assignment is mostly performed by professional accountants, other providers can perform this assignment (Cohen and Simnett, 2015). In this research, the authors are interested in strategies for legitimizing the SA missions of independent third-party bodies. Assurance providers use their website to promote their missions. How do independent third-party bodies legitimize their assurance mission in a regulatory context relating to European Directive 2014/95/EU?

Design/methodology/approach

The authors carried out a discursive analysis of the promotion of SA missions on independent third-party body websites. A content analysis was performed on the collected textual data.

Findings

The results highlight different strategies for promoting the implementation of assurance missions aimed at legitimizing their new skills. Nevertheless, it appears that the providers make very little reference to the quality of nonfinancial information as the objective of SA missions.

Research limitations/implications

The research made it possible to study the promotion of SA through the websites of ITOs. Nevertheless, it would have been interesting to be able to question the ITOs to study their perceptions on their new SA missions.

Practical implications

The research enriches the literature on SA, particularly in a regulatory context relating to European Directive 2014/95/EU. It sheds light on the different strategies put in place by the providers appointed by regulations. From a managerial point of view, the study may allow ITOs to adapt their communication to promote extra-financial missions relating to the European Directive and thus to attract new clients. Finally at the institutional and regulatory level, this research highlights the need to put in place a precise framework relating to extra-financial assurance missions. This may also encourage countries not subject to the verification obligation to introduce such an obligation into their national law.

Originality/value

This is the first study to examine the promotion of SA practice by providers. In addition, very few studies have looked at this practice in a regulatory context and in particular within the framework of the European directive.

Abstract

Describes a study to measure the quality of service provided by food‐poisoning surveillance agencies in England and Wales in terms of the requirements of a representative consumer ‐ the egg producing industry ‐ adopting “egg associated” outbreak investigation reports as the reference output. Defines and makes use of four primary performance indicators: accessibility of information; completeness of evidence supplied in food‐poisoning outbreak investigation reports as to the sources of infection in “egg‐associated” outbreaks; timeliness of information published; and utility of information and advice aimed at preventing or controlling food poisoning. Finds that quality expectations in each parameter measured are not met. Examines reasons why surveillance agencies have not delivered the quality demanded. Makes use of detailed case studies to illustrate inadequacies of current practice. Attributes failure to deliver “accessibility” to a lack of recognition on the status or nature of “consumers”, combined with a self‐maintenance motivation of the part of the surveillance agencies. Finds that failures to deliver “completeness” and “utility” may result from the same defects which give rise to the lack of “accessibility” in that, failing to recognize the consumers of a public service for what they are, the agencies feel no need to provide them with the data they require. The research indicates that self‐maintenance by scientific epidemiologists may introduce biases which when combined with a politically inspired need to transfer responsibility for food‐poisoning outbreaks, skew the conduct of investigations and their conclusions. Contends that this is compounded by serious and multiple inadequacies in the conduct of investigations, arising at least in part from the lack of training and relative inexperience of investigators, the whole conditioned by interdisciplinary rivalry between the professional groups staffing the different agencies. Finds that in addition failures to exploit or develop epidemiological technologies has affected the ability of investigators to resolve the uncertainties identified. Makes recommendations directed at improving the performance of the surveillance agencies which, if adopted will substantially enhance food poisoning control efforts.
