Abstract

Purpose

The purpose of this paper is to research factors like task-orientation and collectivism and to examine the relationship between them and goal-setting as research construct. This research investigates the phenomena of team goal-setting in a selected sports organisation. Therefore 49 players from three Portuguese elite male handball team were selected for the study.

Design/methodology/approach

Three well-known questionnaires were employed to determine the relationships between the above factors in a case setting. Task- and ego-orientation in Sport Questionnaire, the Jackson Psychological Collectivism Measure and the Goal-setting in Sport Questionnaire.

Findings

The results reveal that the team and players are task-oriented, collectivist and possessing professional and personal goal habits. The correlations between questionnaire outcomes indicate that, when the team wants to set goals, it should consider the players’ orientation and the team’s collectivism. Thus team goal-setting is more than only goal-setting, because of the need for task-orientation and collectivism.

Research limitations/implications

The research was conducted using three teams in a specific sports and thus cannot be generalised to the general sports environment. Yet, certainly the strength of the findings indicate that the results and conclusions may be used in a wider sports or business setting.

Practical implications

This research paper should provide managers and coaches with insight into the complexity of team goal-setting. It also should provide insight into the chosen process related to human resources.

Originality/value

The paper adds and demonstrates to the literature on team goal-setting the importance of task-orientation and collectivism as goal-setting mediators.

Abstract

Purpose

This paper aims to evaluate the consumer acceptance of Bordô and Isabel wines from innovative winemaking in order to increase red wine consumption by consumers to obtain nutritional benefits.

Design/methodology/approach

All wines were produced by a standard procedure of vinification. Pre‐drying treatment aimed at drying the grapes up to 22°Brix and static pomace wines presented the constant contact between the must and pomace. Sensory acceptance was carried out by 80 consumers who evaluated eight samples (six experimental wines and two commercial wines) concerning the attributes: appearance, aroma, body, flavor and overall acceptance.

Findings

Experimental wines presented higher acceptance when compared to commercial wines and cluster analysis shows the splitting of consumer preferences, highlighting the higher acceptance of traditional Bordô wine and static pomace samples in all sensory attributes. Pre‐drying process enhances the concentration of coloured compounds, to highlight the appearance acceptance of these samples.

Research limitations/implications

Although this paper has limited the consumer acceptance of red table wines, the innovative treatments will be applied in Vitis vinifera red wines.

Practical implications

The wide acceptance of static pomace and pre‐drying wines has promoted further information about innovative winemaking that can be applied in Brazilian and worldwide wineries.

Social implications

The innovative treatments can change sensorial features of wines and therefore influence the choice of consumers as well as enhancing the nutritional benefits of red wines.

Originality/value

The pre‐drying and static pomace winemaking are the novelty of this study and the wide acceptance of the sensory attributes concerning these treatments indicates the potential for application in wineries.

This study aims to evaluate the effect of grape seed extract on the thermal oxidation of soybean oil.

Abstract

Purpose

This study aims to evaluate the effect of grape seed extract on the thermal oxidation of soybean oil.

Design/methodology/approach

Four treatments were used: soybean oil (SO), butylhydroxytoluene (BHT), antioxidant at concentration of 100 mg/kg in soybean oil (BHTSO), grape seed extract at a concentration of 100 mg/kg in soybean oil (Extract), and mixture at a concentration of 50 mg/kg of grape seed extract (Mixture) and 50 mg/kg of BHT in soybean oil subjected to 180°C for 20 h. The total phenolic compounds were quantified by spectrophotometry using the Folin-Ciocalteu reagent. The antioxidant activity was evaluated by the ABTS•+, DPPH and FRAP acid systems. The fatty acid composition and phytosterols were determined by gas chromatography (GC) and tocopherols were determined by high-performance liquid chromatography.

Findings

Among the treatments studied, the Extract and the Mixture presented lower losses of total phenolic compounds, DPPH and FRAP, while BHTSO had an opposite effect. After 10 h of heating, the Mixture and the Extract were more effective in reducing the formation decomposition products, measured by the amount of total polar compounds. The Mixture resulted in higher retention of essential fatty acids at the end of heating. The Extract and Mixture showed higher retention rates of total tocopherols and the Mixture resulted in 338.71 mg/100 g (P ≤ 0.05) of total phytosterol after 20 h of heating.

Originality/value

Oils undergoing the heating process suffer major changes, requiring the addition of antioxidant compounds. As a result of the questioning on the use of chemical additives, research on natural antioxidants, as substitute to the synthetic ones, is increasing. Among the natural compounds with high antioxidant potential, the grape wastes such as its seeds are highlighted. Studies using grape seed extract are scarce.

Abstract

Purpose

Of the numerous hydrogeochemical river‐water transformations provoked by intense and irrational soil practices, heavy metal contamination by agrochemical usage is the most worrisome. Long‐term metal accumulation can be transported by rainwater, during storms, contaminating rivers. Data on this type of contamination are still scarce, principally in developing countries, such as Brazil. This paper aims to evaluate the influence of agricultural activities on the hydrogeochemistry of the Paracatu River's sub‐basins.

Design/methodology/approach

From a total of 77 points along three sub‐basins, water samples were taken for heavy metal and trace element analyses using spectrometry of atomic emission through plasma (ICP‐OES, Spectro Ciros CCD). The principal water‐quality parameters, such as pH, turbidity, conductivity, oxi‐reduction potential, total dissolved solids (TDS), temperature and dissolved oxygen were measured in situ.

Findings

By incorporating a small drainage area at the monitoring points, it was possible to perceive agriculture's influence (in the form of heavy metal contamination from fertilizers and pesticides) on the water courses.

Research limitations/implications

Although the research was carried out at a total of 77 points for water collection, data are from just one wet season, and need to be repeated.

Practical implications

The results demonstrate a need for monitoring the areas involved with agricultural activities, not only along the main river, but also along small streams that compose the Paracatu Basin.

Originality/value

There is no published literature on this subject regarding the three studied basins.

Abstract

Purpose

The purpose of this paper is to analyse the results of particle size profiles carried out in the dam Mãe d’água, located in the metropolitan region of Porto Alegre, Rio Grande do Sul, becoming a tool of support for geochemistry evaluation works of sediments in this basin.

Design/methodology/approach

The methodology comprised the particle size analysis of eight cores sampled using the extraction profile technique “Sampling Cores.” A total of 56 sub-samples were obtained at different depths, varying between 0 and 52 cm. The particle size analysis of the sub-samples was carried out with the protocol relating to Brazilian analysis standards NBR 7,181; for determination of the particle size distribution of thick sediments, the sieve method was used, and for fine sediments, the pipette method was used.

Findings

The results show that for the different depths, the sediment profiles show similarity in their sedimentary deposition layers. Cores T1, T6, T7 and T8 showed a classification with predominance of mud. Cores T2 and T5 showed variations throughout their sedimentary profile, varying of mud predominance to sand with gravel, and on cores T3 and T4, the predominant characteristic is sand with mud and sand with gravel, respectively.

Originality/value

It can be seen in this paper that energy of sedimentological flow reaches it in a different way, creating these three sectors (first, sand with gravel; second, sand with mud and third, mud) with different characteristics – morphodynamic and sedimentological. These characteristics are important for the study of the heavy metals on the soil and therefore for reducing the risk of contamination of water courses.

Abstract

Purpose

Due to the high levels of crime in Rio de Janeiro, the purpose of this paper is twofold. The first one is to analyze the effects of deterrence variables (such as the adoption of Pacifying Police Units (UPPs) and incarcerations) on violence in the municipalities of the State of Rio de Janeiro, as well as to verify the existence of “revenge effect.” The second is to analyze the effects of socio-economic development on violence, using development indicators.

Design/methodology/approach

Besides usual OLS method for panel data analysis, the study makes use of dynamic panel data framework through D-GMM and S-GMM. The estimates are based on a sample of 82 municipalities of Rio de Janeiro, and the period runs from 2003 to 2013. As dependent variables, the estimates use violent deaths (i.e. aggregation of intentional homicides and armed robberies followed by death) and homicides resulting from opposition to police intervention (i.e. civilians killed as a result of police actions against criminals – “opposition deaths”).

Findings

The estimates indicate that incarceration presents marginal capacity to reduce violence. Regarding the findings for the adoption of UPPs, the evidence suggests that this project increased violence and, therefore, the possibility of displacement of violence to other regions of the State. With respect to the effect of police deaths over violence, the results are unprecedented and suggest the existence of a “revenge effect.” Besides, the study points to the importance of socio-economic development to reduce violence.

Originality/value

Once the study analyzes the effects of incarceration and UPPs, it contributes to the literature by providing new evidence on the ability of anti-crime policies of reducing (or not) violence. In addition, when considering the death of policemen in the estimates, the study shows an unprecedented way, the effect that these deaths cause over violence (the so-called “revenge effect”). Moreover, the study considers the impacts of the development of employment and income, health and education on violence. When analyzing these development indicators, the study contributes with the literature that looks for non-police alternatives to control crime.
