Abstract

The main objective of a 1986 survey of production and operations managers throughout New Zealand industry was to determine the extent of computer use. The survey explored the use of microcomputers, mini computers and mainframes by production managers. Job title and responsibilities of the manager responsible for the majority of production management functions were investigated. It appeared that information and decision making in production management was fragmented in most organisations. The survey examined the main uses of computer information and control systems in production planning and inventory control, the perceived benefits and problems. The main computer brands in use and types of software were also analysed. Comparisons were made with surveys of British companies and some work in the USA.

Abstract

Present and potential uses of microcomputers in teaching operations and production management are examined. Microcomputers are generally available to most students and managers. Difficulties lie in developing the most effective learning methods using microcomputers instead of expecting students to self‐learn entirely by working their way through a program manual in front of a screen. Potential uses of microcomputer‐based simulations and the possible learning benefits are explored. Uses of an aggregate planning case study are given as an example, involving manual calculations, group discussion and a microcomputer spreadsheet. The example shows how small groups can learn more effectively about the power and speed of microcomputers by using them in a real situation. The simulation emphasises the useful role of micro‐computers as an integral part of operations planning systems and decision‐making processes.

Abstract

Purpose

As the Syrian civil war winds down, the massive reconstruction of the devastated cities has become a recurring subject of political and scientific discussions. A crucial question pervades all these debates: is the current legal framework adequate for confronting the reconstruction challenges in an effective way? With the purpose of understanding and informing the question, this study aims to analyze the most important legal instrument for the Syrian urban reconstruction, Law 10/2018.

Design/methodology/approach

A functional analysis of the legal text and of its effective implementation is provided. Following a doctrinal legal approach, internal inconsistencies are highlighted, as well as possible “legal gaps” that might allow and favor instances of disrespect of the rule of law and regulatory capture.

Findings

The main hypotheses discussed are, first, from a descriptive-analytical perspective, that the neoliberal trend in the Syrian political economy underpins the legal framework for the Syrian reconstruction. Second, from a design perspective, that, while offering a strong mechanism for disciplining the Syrian urban planning, Law 10/2018 does not warrant a scenario of respect of the rule of law and seems too easy prey for regulatory capture.

Originality/value

While the most recent and prominent legal instrument aimed to frame Syrian post-war reconstruction, Law 10/2018, has been subject to multiple policy analyzes and critiques, these have focused almost exclusively on its presumed warchitecture dimension, lacking contextual depth and, most worryingly, ignoring any kind of doctrinal legal analysis. Setting the Law 10/2018 in its legal context is something that has not been done yet, even if, according to their own ontology, legal provisions have to be understood within the context of the legal system they are inserted in. This paper delves into the subject, analyzing the legal text, its juridical context and the way it has been interpreted by the administrative decision-maker while looking at instances where the axiological goals constitutionally proclaimed and legally enshrined might be prevented by the very regulatory configuration.

Abstract

Consumer-Directed Health Plans (CDHPs) are proposed as an option to control healthcare costs. No research has addressed their applicability in rural settings. This study analyzes three years (2003–2005) of healthcare expenditure and utilization incurred by two employers and a national carrier providing data from a rural state, Kentucky. The study included two measures of expenditures (health care and prescription drugs) and three measures of utilization (physician visits, hospital admissions, and hospital inpatient days). In general, the CDHP successfully controlled the growth of medical costs. These findings suggest that CDHPs may be a viable alternative benefit structure for rural employers.

Abstract

Purpose

Refractance window drying (RWD) has been identified as the method that can give high-quality products at a relatively low production cost. However, knowledge about its use and adoption remains lacking both in academic curricula and industry in the developing world.

Design/methodology/approach

A lab-scale batch RWD of a closed-loop control system was designed, fabricated and evaluated for drying rates, evaporation rate, the energy of evaporation, energy efficiency and throughput. Testing was done using mango and tomato pulps.

Findings

Drying rates at 95°C of 1.32 gg−1min−1 and 0.854 gg−1min−1 at 2 and 3 mm, respectively, for tomato, 0.6 gg−1min−1 and 0.33 gg−1min−1 at 2 and 3 mm for mango pulp were obtained. The dryer had an evaporation rate of 4.63 × 10–4 kg/s and 4.25 × 10–4 kg/s, the energy of evaporation of 1.05 kW and 0.96 kW and thermal energy efficiency of 25.64% and 21.73% while drying tomato and mango pulps, respectively. Dryer throughput of 0.6 kg/h of dried mango Pulp and 0.47 kg/h of dried tomato pulp was obtained.

Originality/value

The designed RWD can be adequately used in laboratory experiments on different products to produce powders. This will enable the transfer of knowledge about RWD technology in developing countries.

Abstract

On the basis of a survey of 1,300 employees from the Australian telecommunications industry, examines the impact of computer usage on job satisfaction. Results reveal that job satisfaction is positively influenced by the extent of computer usage, aspects of computer‐related training and demographic characteristics such as tenure and job position. However, by catering for different areas of computer‐usage and by controlling for job‐position and tenure, it was found that usage in different functional areas (by different sub‐groups) tended to affect user satisfaction to a different degree. The results illuminate some of the human resource and training issues and challenges that organizations engaged in extensive computerization may need to address.

Abstract

Purpose

During the coronavirus disease 2019 (COVID-19) pandemic, ubiquitous social media has become a primary channel for information dissemination, social interactions and recreational activities. However, it remains unclear how social media usage influences nonpharmaceutical preventive behavior of individuals in response to the pandemic. This paper aims to explore the impacts of social media on COVID-19 preventive behaviors based on the theoretical lens of empowerment.

Design/methodology/approach

In this paper, survey data has been collected from 739 social media users in China to conduct structural equation modeling (SEM) analysis.

Findings

The results indicate that social media empowers individuals in terms of knowledge seeking, knowledge sharing, socializing and entertainment to promote preventive behaviors at the individual level by increasing each person's perception of collective efficacy and social cohesion. Meanwhile, social cohesion negatively impacts the relationship between collective efficacy and individual preventive behavior.

Originality/value

This study provides insights regarding the role of social media in crisis response and examines the role of collective beliefs in the influencing mechanism of social media. The results presented herein can be used to guide government agencies seeking to control the COVID-19 pandemic.

Abstract

Purpose

This study aims to evaluate the extent to which similar team mental models (TMMs) at the beginning of a team's lifecycle influence the level of relationship conflict within the team, TMM-similarity at the middle of the team lifecycle, and in turn team effectiveness. Thus far, no research has analysed the mediating role of a dysfunctional team process between TMM-similarity and effectiveness.

Design/methodology/approach

The study was conducted in a strategy and management competition involving 414 individuals who comprised 92 teams (3-5 members). Data were collected at four moments in time. The questionnaires were developed based on validated scales and adapted for the specific context.

Findings

The results provide support for the mediating role of conflict between the similarity of team-TMMs at the beginning of team lifecycle and effectiveness. The results also provide support for the mediating role of task-TMMs in the middle of team lifecycle between task-TMMs at the beginning of team lifecycle and effectiveness. Findings suggest that teams with more similar TMMs, experience less relationship conflict which in turn improves effectiveness.

Research limitations/implications

In this study TMM-accuracy was not analysed. Future research should analyse the role of TMM similarity and accuracy. Further, future research should explore the optimal level of TMM-similarity and when the similarity of TMM is disruptive to teams.

Originality/value

This paper sheds light on the role of conflict as a dysfunctional team process between TMM-similarity and effectiveness. Moreover, this paper shows that more research on TMM evolution is needed.

Abstract

Purpose

An underlying assumption in the shared mental model (SMM) literature is that SMMs improve whilst team members work together for longer. However, whether dyad members indeed have higher perceived SMMs with higher shared tenure has not been explored. This study aims to, therefore, firstly, investigate this idea, and we do so by focusing on perceived SMMs at the dyadic level. Secondly, because in today’s fast-paced world perceived SMMs often need to be built quickly for dyads to perform, we assess if goal interdependence can reduce the dyadic tenure required for higher perceived SMM similarity. Thirdly, we analyse if these processes are related to dyadic performance.

Design/methodology/approach

We collected a dual-source sample of 88 leader–member dyads across various industries. We conducted PROCESS analyses to test their first-stage moderated mediation model.

Findings

Results showed that dyadic tenure was positively related to perceived SMM similarity, and that goal interdependence moderated this relationship. Additionally, perceived SMM similarity mediated the relationship between dyadic tenure and dyadic performance. Lastly, the overall moderated mediation model was supported.

Originality/value

We contribute to the perceived SMM literature by: investigating perceived SMMs in dyads, testing a key idea regarding the influence of dyadic tenure on perceived SMMs and investigating how goal interdependence may prompt perceived SMM similarity earlier in dyadic tenure and, ultimately, improve dyadic performance.

Abstract

Purpose

The purpose of this study is to develop functional chicken patties with incorporation of mango peel powder as a fat replacer.

Design/methodology/approach

Low-fat chicken patties were developed by incorporating mango peel powder as fat replacer at 1.0, 2.0 and 3.0% level to replace 50% vegetable oil in the formulation. The product was evaluated for various physico-chemical properties and sensory attributes.

Findings

There was a significant difference (p < 0.05) between control and treatments for all physico-chemical properties except product pH and protein content. The emulsion pH, emulsion stability, water activity, fat and cholesterol content of mango peel treated chicken patties were significantly (p < 0.01) lower, however, cooking yield, moisture content, fat retention and moisture retention values were significantly (p < 0.01) higher than control. All mineral content decreased significantly (p < 0.05) in treatments except potassium and phosphorous content. Incorporation of mango peel powder had a significant (p < 0.05) effect on textural and colour parameters. Sensory scores decreased significantly (p < 0.05) in treatments, however, the product was well acceptable up to 2% of mango peel powder incorporation.

Originality/value

Fat has an important role in comminuted meat products, its reduction results in rubbery and dry textured products and poses difficulties in terms of flavour and texture. Meat products with high-fat content may exert a great harmful effect on human health such as obesity and high blood cholesterol level. Hence, there is a need for using suitable ingredient, which is able to replace fat without affecting quality. Mango peel may be used as suitable fat replacer at 2% to replace 50% added vegetable fat without affecting quality parameters.
