Abstract

Purpose

The past few decades have produced a number of investigations into the correlation between project managers’ competencies and project success. As a result, competencies lists have become extensive “shopping lists.” The purpose of this paper is to define the most important competencies to project success and investigate their correlations.

Design/methodology/approach

The authors surveyed project managers on the importance of 28 project manager competencies to project success. Data were analyzed using univariate and multivariate procedures.

Findings

Data show that communication, commitment and leadership appear as the three most relevant aspects. Multivariate analysis identified seven groups of competencies: leadership, self-management, interpersonal, communication, technical, productivity and managerial.

Practical implications

The results confirm a growing trend toward soft skills and reinforce the need for an update on project management education to fill the gap between theory and practice.

Originality/value

Project manager competencies lists have become too extensive, and the field is in constant change; therefore, this study updates the discussion and downsizes the number of competencies to fewer, more relevant items.

Abstract

Purpose

The purpose of this study is to assess the effect of a diet added with taro (Colocasia esculenta) flour on the body composition of rats.

Design/methodology/approach

Weanling male rats were divided into Control (n = 11) and experimental groups (Taro, n = 12); experimental rats were fed on taro for 90 days. Food intake, body mass and length were evaluated on a weekly basis. Body composition was assessed through dual-energy X-ray absorptiometry and intra abdominal fat mass was measured at the end of 90 days.

Findings

Taro group recorded protein intake (55.5 ± 14.1 vs 43.8 ± 12.8 kcal, P < 0.009), body mass (between 40 and 90 days, P < 0.05), fat mass (147.3 ± 7.7 vs 99 ± 6.1 g, P < 0.001), lean mass (282.8 ± 4 vs 253.5 ± 7 g, P < 0.001), trunk fat mass (97.1 ± 7.7 vs 71.5 ± 4.1 g, P < 0.010), as well as intra-abdominal (31.3 ± 1.9 vs 21.1 ± 1.7 g, P < 0.001), epididymal (9.2 ± 0.8 vs 4.7 ± 0.5 g, P < 0.001) and retroperitoneal (14.2 ± 0.9 vs 8.8 ± 1.2 g, P < 0.002) fat mass higher than that of the Control group.

Originality/value

Taro flour would show anabolic effects on body compartments of rats. The extrapolation of these findings herein recorded for rats to humans requires caution; however, it is necessary conducting further studies to investigate potentials anabolic effects of taro (Colocacia esculenta) flour on the body composition of physical training models.

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

This paper aims to describe the likely positive effects of alpha-linolenic acid supplementation on the lung and the negative effects of it on the adipose tissue of COVID-19 patients.

Design/methodology/approach

This paper focuses on investigating the effects of alpha-linolenic (ALA) on the respiratory system and adipose tissue of COVID-19 patients.

Findings

ALA can help human respiratory system by improving lung damage. On the other hand, when it comes to adipose tissue, it can induce the overexpression of glucose transporter-4 gene and impair COVID-19 prognosis.

Originality/value

Despite the inconclusive pieces of evidence, improving the quality of patients’ diet may help mitigating their risk of developing severe COVID-19 infection. Further research studies are necessary to help finding a safe ALA recommendation focused on preventing and improving lung damage, as well as on stopping adipose cells from working as COVID-19 reservoirs.

Abstract

Purpose

The purpose of this study was to development of a new chocolate-flavored powdered food supplement enriched with mesquite pod flour, oak extract and agave fructans, with proper sensory characteristics as well as its physicochemical and glycemic quality.

Design/methodology/approach

A powdered shake was formulated using experimental design (23) with mesquite (Prosopis laevigata) pod flour, oak (Quercus convallata) extracts, nonalkalinized cocoa, agave fructans, milk protein and xanthan gum. Sensory analysis (choice profile method, ranking test, focus group, quantitative descriptive analysis), moisture, ash, fiber, protein and lipids, pH, color, wettability, dispersibility and rheological tests were done. Phenolic profiling analysis to samples was done by ultraperformance liquid chromatography coupled to photodiode array detection and electrospray ionization tandem mass spectrometry, antioxidant activity was measured by 2,2’-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation, ferric reducing antioxidant power and oxygen radical absorbance capacity, glycemic index (GI) and glycemic load were evaluated.

Findings

The main sensory attributes in the powders were chocolate, bitter, astringent, grass/linseed flavors (p < 0.05). The product has protein [66.9%], carbohydrates [22.0%], lipids [1.6%], ash [2.7%] and moisture [6.8%], with wettability (23 s), and dispersibility of 77.9%. Catechin, epicatechin, gallocatechin, procyanidin B2, chlorogenic, coumaric and ferulic acids were identified. GI and caloric load not show differences between men (73.3±2.4, 4.4±0.1) and women (67.0±2.1, 4.1±0.1) (p > 0.05).

Originality/value

The use of mesquite pods, oak and agave fructans in powder food supplement is an alternative to obtain a product high in protein, with good sensory properties, antioxidant activity and moderate GI.

Abstract

Purpose

The contribution of project success and the organisation's efficiency is consensual in the literature. However, the value of project management (PM) brings to the organisation's effectiveness through the alignment with strategy, contributing to its competitiveness and business success, is yet little explored. This study addresses the literature gap that concerns the relationship between PM and the organisation's competitiveness, proposing a holistic conceptual model to understand of how PM brings value to the organisation. This work also aims to demonstrate the practical implications of theoretical contributions to the value of PM. For this, a detailed action research (AR) was planned to show how researchers and practitioners could work and collaborate in a real problem and prove the AR approach's adequacy to the PM field.

Design/methodology/approach

The methodology starts with a systematic literature review (SLR), followed by content analysis to develop a conceptual model of PM's value. To validate the theoretical constructs and transfer the results to real context, an AR plan is then carried out to support a specific PM problem presented by an automotive industry company.

Findings

The results have theoretical and practical implications. An original conceptual model is developed–the value of PM: Key factors–defending a multidimensional and holistic perspective to understand the PM's value. A set of key factors was identified, structured, interrelated and exemplified their practical implementation in a single company. In addition to the technical key factors identified in the literature review, the AR plan unveils crucial social aspects to improve PM's value, such as leadership, strong communication and open processes. This work shows the central role of PM methodologies in integrating and interconnecting the key factors, emphasizing the projects' strategic level.

Research limitations/implications

The present work was developed in a specific and particular organisational context and industry.

Practical implications

The AR plan presents a company's original programme–Hyper Competitiveness (HC) Temple–implemented in an automotive company. Project management professionals could understand how this company implemented each key factor, defended in a conceptual model and lead the project's results to the business value.

Originality/value

The research originality lies in rethinking PM's value to organisations from a holistic perspective: multi-dimensional, temporal, life cycle, multi-organisational, pointing out a set of technical and social key factors.

Abstract

Purpose

The study aims to investigate how the action research contributes to the collective construction of a discipline in management. This issue was the motivation for the present study, which was developed from the experience of master's degree students attending the post-graduate program in management of an institution in the State of Bahia, Brazil.

Design/methodology/approach

The overall objective of this study is to understand the method's effectiveness for this aim, whereas the specific objectives are to identify the commitment of the subjects in the activities proposed and to assess the effectiveness of the use of active methods in the discipline construction. The theoretical background is regarding digital education transformation, active teaching methods and action research. As for the qualitative perspective, the methodological approach of choice was that of participant observation (for data collection) and content analysis.

Findings

It was possible to highlight the awakening of critical sense and the effectiveness of action research in enhancing the protagonism of the master's degree students in the construction of their own knowledge.

Originality/value

This study not only contributes to the field of applied social sciences but also opens a precedent for the experience of collective construction of a discipline in another area of knowledge by means of action research. Another factor demonstrating the relevance of this study is the production of essays and articles by master's degree students in which active methodologies were related to themes of interest.
