Abstract

Purpose

The purpose of this paper is to explore the connections between human resource (HR), situation strength and improvisation behavior. A high degree of “fit” among HR practices and between such practices and organizational strategy, is said to have an impact on organizational outcomes. How these fits are achieved is not fully understood in the literature. It has been proposed that horizontal fit is achieved when messages regarding HR matters are communicated to employees in a distinct, consensual, and consistent way. This will create a strong situation, which in turn will affect outcomes such as improvisation behavior. Situation strength is captured by the concepts of climate strength, and culture strength.

Design/methodology/approach

The research was conducted at a call center of a company belonging to a Portuguese Telecommunications Group. In total, 91 questionnaires were collected. Scales in the questionnaire are based on existing indicators, but a new measure of HR strength (HRS) was also used. The data were analyzed with structural equation modeling.

Findings

Results show that HRS has a direct effect on improvisation behavior. Furthermore, culture is a mediator between HRS and climate. There was also a strong indication that culture may be a mediator between HRS and improvisation behavior.

Research limitations/implications

Limitations concern the sample size and the fact that research was conducted in a call center. Implications for research include the need to introduce leadership into this type of studies, as well as model and scales validation.

Originality/value

The current research advances knowledge in the area in three ways. First, it presents a new instrument to measure HRS. Second, it introduces improvisation as an outcome of HR. And third, it tests a full model that links HR to social common structures (climate and culture) and performance outcomes (improvisation behavior in this work).

Abstract

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract

Purpose

The purpose of this study was to evaluate the increase in sensitivity of a single risperidone administration in relation to energy intake of Wistar rats treated with cafeteria diet from birth to adulthood (119 days).

Design/methodology/approach

During the lactation period, six litters of Wistar rats (dam + 8 pups each litter) were fed one of the following two diets: Control (n = 3) or Cafeteria (n = 3) diets and water ad libitum. After weaning, the males were placed in individual cages, receiving the same diet offered to their respective dams (Control = 18; or Cafeteria = 18) until adulthood (119 postnatal days). The following parameters were evaluated: food and energy intake; macronutrient intake; weight gain; adipose tissue relative weight; sucrose preference; food intake after an administration of risperidone (0.1 mg/kg body weight).

Findings

The Cafeteria group showed a higher energy intake in relation to the Control group (p < 0.001). The consumption of energy beyond the individual needs can be understood as a hyperphagic condition. Also, the Cafeteria group reported greater weight gain (p = 0.048) and accumulation of adipose tissue (p < 0.001) with respect to the Control group. These results indicate that the cafeteria diet generated obesity in animals. The Cafeteria group showed reduced sucrose preference (p = 0.031), which is associated with the development of anhedonia-like behavior. In the food intake test, risperidone showed a greater sensitivity in Cafeteria animals, promoting a decrease in their energy intake in relation to the Control group that received risperidone (p = 0.040).

Originality/value

The cafeteria diet promoted hyperphagia, anhedonia-like behavior and obesity in animals. Acute risperidone administration showed greater sensitivity in the Cafeteria group, with a decrease in energy intake. The reported effects may be related to a downregulation of the dopaminergic system in the NAc region.

Abstract

Purpose

The purpose of this paper is to evaluate the pathological, biochemical and redox state parameters of liver tissue in Wistar rats treated from birth to adulthood (119 days) with cafeteria diet.

Design/methodology/approach

During the lactation, 6 liters of Wistar rats (dam + 8 pups each) were fed one of two diets: control (CTRL; n = 3) or cafeteria (CAF; n = 3) diets and water ad libitum. After weaning, the males were placed in individual cages, receiving the same diet offered to their respective dams (CTRL or CAF; n = 18) until adulthood. The following parameters were evaluated: absolute and relative liver weight; blood, liver and feces biochemistry; liver histology; and redox state of the liver.

Findings

When assessing the relative and absolute organ weight, no significant differences were found between the groups. The Cafeteria group exhibited higher values of serum LDL-c (p = 0.008), VLDL-c (p = 0.03) and triglycerides (p = 0.01), as well as several micro and macrovacuoles of fat accumulation, higher hepatic lipid (p = 0.03) and cholesterol (p = 0.0001) levels regarding Control group. Cafeteria group showed greater expression of glutathione-s-transferase (p = 0.03) and superoxide dismutase (p = 0.005) enzymes compared to the control group. In the case of the markers of oxidative stress, there was no difference between the groups.

Originality/value

A simple and standardized cafeteria diet caused an accumulation of fatty acids in liver tissue, inducing a state of hepatic steatosis besides an increased expression of antioxidant enzymes.

Abstract

Purpose

The pandemic has reinforced the need for revamping the healthcare service delivery systems around the world to meet the increased challenges of modern-day illnesses. The use of medical cyber–physical system (MCPS) in the healthcare is one of the means of transforming the landscape of the traditional healthcare service delivery system. The purpose of this study is to critically examine the impact of MCPS on the quality of healthcare service delivery.

Design/methodology/approach

This paper uses an evidence-based approach, the authors have conducted a systematic literature review to study the impact of MCPS on healthcare service delivery. Fifty-four articles were thematically examined to study the impact of MCPS on eight characteristics of the healthcare service delivery proposed by the world health organisation.

Findings

The study proposes support that MCPS will positively impact (1) comprehensiveness, (2) accessibility, (3) coverage, (4) continuity, (5) quality, (6) person-centredness, (7) coordination, (8) accountability and (9) efficiency dimension of the healthcare service delivery. The study further draws nine propositions to support the impact of MCPS on the healthcare service delivery.

Practical implications

This study can be used by stakeholders as a guide point while using MCPS in healthcare service delivery systems. Besides, healthcare managers can use this study to understand the performance of their healthcare system. This study can further be used for designing effective strategies for deploying MCPS to be effective and efficient in each of the dimensions of healthcare service delivery.

Originality/value

The previous studies have focussed on technology aspects of MCPS and none of them critically analysed the impact on healthcare service delivery. This is the first literature review carried out to understand the impact of MCPS on the nine dimensions of healthcare service delivery proposed by WHO. This study provides improved thematic awareness of the resulting body of knowledge, allowing the field of MCPS and healthcare service delivery to progress in a more informed and multidisciplinary manner.
