Abstract

Purpose

This study aims to assess the influence of partial and simultaneous substitution of fat and sodium by hydrolyzed collagen and mix of herbs (MH) in chicken hamburgers, on the physical properties and proximal composition.

Design/methodology/approach

Five formulations were developed: (1) HCON–without adding collagen and MH; (2) C25M25–adding 25% of collagen and 25% of MH; (3) C25M50–adding 25% of collagen and 50% of MH; (4) C50M25–adding 50% of collagen and 25% of MH and (5) C50M50–adding 50% of collagen and 50% of MH. Chicken hamburgers were analyzed by proximal composition, sodium content, collagen and color analysis. The influence of treatments on texture profile, cooking performance and lipid oxidation of chicken hamburger was also investigated.

Findings

There was reduction in lipid and sodium for modified formulations compared with the HCON. There was great influence for some parameters, such as luminosity, cooking performance and texture profile. The formulation C50M50 showed the best cooking performance when compared to the others.

Originality/value

The formulation adding 50% of collagen and 50% of MH showed the highest yield and water retention (WR), with the least reduction in diameter and shrinkage, as well as presenting the best indexes of the texture profile and the lowest oxidation index, being recommended as the best combination of fat and sodium replacement.

Abstract

Purpose

The purpose of this study is to investigate which emotions and difficulties in the emotional regulation of adolescents with illicit substance consumption.

Design/methodology/approach

In total, 41 adolescents undergoing treatment for the use of alcohol and drugs were recruited. The instruments used were the emotional rating scale and the difficulties in the regulation of emotions scale.

Findings

Emotional reactivity showed significant differences in the sadness dimension in relation to the number of cannabis cigarettes smoked daily and length of stay, and in the surprise dimension in relation to the number of cannabis cigarettes smoked daily. There was a significant correlation between happiness and age, surprise and number of siblings, sadness and school absenteeism and fear, school absenteeism and number of substances consumed. In regard to difficulties in emotional regulation, there were significant differences between the groups, in strategies regarding the gender of the participants and the number of substances consumed, in non-acceptance and impulses and in the number of substances consumed and in the awareness of the type and number of substances consumed. There was a significant correlation between strategies, non-acceptance, awareness and impulses and the number of substances consumed.

Originality/value

This study demonstrated that the emotional problems of adolescents admitted to a therapeutic community are predictors of illicit substance use.

Abstract

Purpose

This article introduces a model of knowledge creation in consciousness, the creation of explicit knowledge in six forms and its register and organisation in documents.

Design/methodology/approach

Assuming the premise of three realms of reference to knowledge and two forms of reference to entities, this article, through a phenomenological perspective, deduces a model of the creation of knowledge in consciousness and the creation of explicit knowledge in six forms and its register in documents.

Findings

Two basic types of knowledge are introduced: situated knowledge and theoretical/normative knowledge. Considering three realms of reference of knowledge – the space–time realm, subjectivity realm and linguistic realm – six general types of knowledge are deduced. Finally, three layers of knowledge organisation are presented: classification and mapping documents, theoretical/normative documents and documents of situations.

Practical implications

This article can contribute to the development of more efficient forms of creation of explicit knowledge, its register in documents and the development of more efficient knowledge organisation and management systems.

Originality/value

Relying on established perspectives of the realms where subjectivity is immersed, this article discusses how knowledge is created in consciousness and registered in documents. It also presents a novel perspective of types of knowledge through the combination of dimensions, realms of reference and forms of reference to entities.

Abstract

Purpose

Effective cognitive functioning elucidates the orchestrated interplay of diverse mental faculties in addressing daily tasks, potentially indicative of an improved state of an individual’s health. Linked to this is the potential role of life satisfaction, which may aid individuals in better managing their health-related challenges. The purpose this study is to examine whether the cognitive functioning and life satisfaction levels of elderly individuals serve as predictors of their subjective health complaints.

Design/methodology/approach

The research involved a cohort of 126 elderly community residents. The assessment tools used encompassed a socio-demographic questionnaire, the mini-mental state examination (MMSE), the scale of subjective health complaints and a life satisfaction scale.

Findings

The findings reveal that both cognitive functioning and life satisfaction are predictive variables for subjective health complaints, validated in both the original sample and simulated samples.

Originality/value

This study’s innovation lies in highlighting the importance of cognitive functioning and life satisfaction among the elderly population as explanatory factors for subjective health complaints. Consequently, these dimensions warrant consideration in specialized intervention programs aimed at promoting the health and quality of life among the elderly.

Abstract

Purpose

The purpose of this study is to verify the effect of general cognitive functioning and positive and negative affects on loneliness in the elderly people and to analyze the mediating effect of positive affects on the relationship between negative affects and loneliness.

Design/methodology/approach

The sample of this study consists of 61 people with an average age of 83 years who receive specialized institutional support. Study participants answered a set of questionnaires in which their sociodemographic characteristics, characteristics of the support received, cognitive functioning, positive and negative affects and loneliness were assessed.

Findings

Cognitive functioning did not reveal a significant relationship with loneliness. On the other hand, there was a positive and significant relationship between negative affects and loneliness and a significant marginal relationship between positive affects and loneliness. Negative affects proved to be predictors of loneliness, and there was an influence of positive affects by mediating the relationship between negative affects and loneliness.

Originality/value

This study showed that negative affects are risk factors for the appearance of loneliness in the elderly people who receive specialized institutional support and should be considered in intervention programs that aim to reduce loneliness and social isolation of the elderly people.

Abstract

Purpose

The purpose of this paper is to construct a numerical model for the numerical analysis of the hydraulic transient profile in Trabalhador channel for filling and emptying maneuvers and to determine the water level in time. Model results support operational managers in the decision-making process.

Design/methodology/approach

Physical data were provided for the construction and calibration of the numerical model. The equations of Saint-Venant were approximated by a finite difference scheme and the numerical model was written in Fortran. The results of filling and emptying of the channel simulations were compared with the measured water levels.

Findings

Measured water levels and those simulated by the numerical model have shown good correlation. The time recorded for the filling and emptying of the canal was also close between the measured and simulated data. The simulation design flow pointed to inundation in the channel banks. Simulation water levels were slightly higher than those measured.

Research limitations/implications

In this model, the combination of canals and pressure conduits was not considered.

Practical implications

The findings confirm the measured time for filling and emptying of the canal, as well as inundation of canal banks for the maximum design flow. These results help in the management process.

Originality/value

This paper presents a numerical model for hydraulic transient analysis in channels with good agreement with the field data.

Abstract

Purpose

This study aims to examine the price and income elasticities of short- and long-run industrial electricity demand in Brazil between 2003 and 2020. The research also examines the impacts of COVID-19 in Brazil’s industrial electricity sector, including an analysis in states more and less industrialized.

Design/methodology/approach

Dynamic adjustments models in panel data are used to present robust estimates and analyze the impact of different methodologies on reported elasticities.

Findings

The short-run price elasticity is estimated at −0.448, while the long-run values are around −1.60. Regarding income elasticity, the value is 0.069 in the short-run and is concentrated in 0.25 in the long-run. The inelastic results of income show that the industrial demand for electric energy follows the trend of loss of competitiveness of the Brazilian industry in the past years. In addition, the price of natural gas, the level of employment, and, in specific cases, the level of imports also influence industrial electricity demand.

Originality/value

The research is a pioneer in the investigation of the industrial behavior of electricity of the Brazilian industrial branch, using as control variables, the average temperature, and the level of rainfall, this one, so important for a country whose main source is hydroelectric. In addition, to the best of the authors’ knowledge, it is the first study, which is prepared to analyze the effects of COVID-19 on electric consumption in the industrial sector, investigating these impacts, including in the states considered more and less industrialized. The estimates generated may help in the design of the Brazilian energy policy.

Abstract

Purpose

This study aims to analyze the relationship between the adherence to critical chain project management (CCPM) practices and the new product development performance, in terms of the results of product development programs and product portfolio management (PPM).

Design/methodology/approach

A survey was conducted with 79 innovative companies operating in Brazil. Data were analyzed using correlation analysis and non-parametric tests.

Findings

Significant and positive correlations were found between CCPM adoption and the performance factors proposed. The adoption of CCPM offered stronger correlation with PPM performance than with the adoption of traditional methods. The results further indicate a possible indirect contribution of CCPM practices to the product development program by means of PPM improvement.

Originality/value

This study deepens the knowledge of the joint study between project management and new product development, by bringing empirical evidence that the adoption of specific practices suggested by CCPM is used by organizations with superior performance. Moreover, the results broaden CCPM literature by attesting that companies do not necessarily have to apply the CCPM approach in a formal and explicit way to obtain the performance results given. The analyses still have practical value when indicating which CCPM practices should be prioritized by managers seeking high performance in PPM.

Abstract

Purpose

Agribusiness has stood out in the economy sector as a form of countryside-city interaction due to its productive chain characterized by modernization coming from cities, especially in the industrial area. Thus, the present study analyzed corporate social responsibility (CSR) in the context of agribusiness, based on a survey of articles published in the Scopus database. The main objective of the research is to analyze whether the agribusiness sector has incorporated CSR into its internal policy.

Design/methodology/approach

For this, the methodology used was researching through a systematic literature review, in which 14,720 documents on CSR were found. When restricting the search for CSR in agribusiness, 44 articles were found, and it was noticed that three were based on analysis in Latin America, which were the object of the study.

Findings

From this, it was realized that the literature on the subject is scarce, but of fundamental importance for its adoption in the sector, as it brings economic and environmental benefits not only to companies but also to society as a whole.

Research limitations/implications

Although CSR is not yet the total solution to socioeconomic and environmental problems, it can be used as a strategy for raising companies’ awareness, based on the development of an organizational environmental culture, which brings competitive advantages over competitors who adopt them.

Originality/value

The topic of CSR is a recent discussion in the academic field, which is why it has few studies. Thus initially, we sought to analyze it in the scenario in Latin America, as presented in the present work. However, as a future stage of research in the area of CSR, this topic will be analyzed as an academic master’s degree in the context of the BRIC countries.
