The main goal of this paper is better understand the risk/return trade-off of investing in socially responsible investment funds (SRIF) and green investment funds (GIF).

To achieve our aim a green investment fund portfolio, a socially responsible investment portfolio and a conventional fund (CF) portfolio from the United States of America (USA) were selected to compare the efficiency of these three different portfolios, by using Value-Based Data Envelopment Analysis (DEA) methodology.

The results point out that SRIF and GIF are more efficient than CF. For five years, the CFs have not outperformed the GIF.

The results suggest that there is a growing awareness on the part of investors that sustainable companies are the companies that will allow a better quality of life and a more sustainable environment. It seems that somehow managers and investors are aware that the market will compensate them for thinking about a cleaner and more equitable world.

The use of insects as food is a proposed solution for the increased demand for food worldwide, but it lacks acceptance because of restrictive emotional factors. This article aims to understand better customers' emotions’ role in considering and consuming insect-based food.

To assess their acceptance, an experiment was developed with 38 participants living in Portugal to identify how people feel when consuming processed insect bars compared to cereal bars (of equal flavour). A video was recorded “before”, “during” and “after” the consumption of such foods, and the triggered emotions and affective states were identified using the Facial Action Coding System (FACS) and the circumplex model of affect, respectively. After consumption, the Self-Assessment Manikin (SAM) was asked to be completed.

It was observed that the valence and arousal of the emotions and affective states triggered during consumption were higher in the insect bar than in the cereal bar. Its consumption resulted in surprise and a positive evaluation. Processed insect-based foods may result in a potentially increased acceptance of this new food alternative in the market.

Prior studies briefly identified disgust as a primary emotion activated by insect-based food. The current research deeply studied emotional responses to insect-based processed foods in the Western world using the dimensional emotional models. This study offers arguments for the insect-based food industry to invest in processed food justified by its potential for acceptance. In addition, it motivates further research focused on other insect-based products (e.g. non-processed ones).

This study aims to verify the antecedents influencing mobile gamers’ intentions to purchase mobile phones. To this end, the constructs price–quality relationship, price sensitivity, perceived quality, identification with the group of gamers and referrals from other gamers were identified in the literature.

Data were collected through an online questionnaire with 335 consumers. The model was tested using partial least squares.

It was verified that the price–quality relationship directly influences mobile gamers' intentions to purchase mobile phones. Also, it was observed that price sensitivity of mobile gamers directly influences the price–quality relationship and indirectly influences the intention to purchase mobile phones to play games. It was further verified that this price sensitivity is directly influenced by the perceived quality of mobile gaming devices. Finally, it was observed that referrals from other gamers directly influences the perceived quality and onès identification with the group of gamers.

This study concluded that developing strategies focused on prices of mobile phones gamers use to play games tends to influence mobile gamers' purchase intentions. This paper extends the study of mobile device purchase behavior, uniting constructs studied separately and proposing connections not yet tested, assisting in the theoretical understanding of the factors that contribute to the intention to purchase mobile devices.

This study is theoretically justified for four reasons: it focused on a specific group of consumers, mobile gamers, which is a constantly growing audience; it brought an innovative model, testing the influence of the perceived quality of mobile gaming devices on the price sensitivity of mobile gamers; there are spaces for new research on mobile device purchase intention; and it may assist in the theoretical understanding of the factors contributing to mobile device purchase intention.

Entrepreneurship is a phenomenon strongly associated with economic growth, development and employability, leading countries to compete and often produce reforms to ensure good levels of entrepreneurship. In this sequence, this study aims to know which types of economies present favourable institutional environments for entrepreneurs, exploring the link between the ease of doing business and the three levels of economic development (innovation-driven, efficiency-driven and factor-driven) of 137 economies.

A quantitative methodology through an analysis of variances was adopted, gathering data from the ten pillars proposed by the World Bank in the Doing Business 2019 – training for reforms report, and economic development levels, provided by Global Competitiveness Report (2017–2018).

In the light of institutional theory, the results showed that innovation-driven economies are more competitive, presenting more robust institutional environments for entrepreneurs than factor-driven and efficiency-driven. There is only one exception in the Getting Credit pillar.

This study clarifies some assumptions in the previous literature that developed economies have better business environments, being the first one to establish this relationship directly. Some practical implications, especially for international entrepreneurs in the decision-making phase on which type of economies to carry out their investments and policymakers and researchers, were provided in this study.

On the one hand, this paper is to further understand the residents' differentiated power consumption behaviors and tap the residential family characteristics labels from the perspective of electricity stability. On the other hand, this paper is to address the problem of lack of causal relationship in the existing research on the association analysis of residential electricity consumption behavior and basic information data.

First, the density-based spatial clustering of applications with noise method is used to extract the typical daily load curve of residents. Second, the degree of electricity consumption stability is described from three perspectives: daily minimum load rate, daily load rate and daily load fluctuation rate, and is evaluated comprehensively using the entropy weight method. Finally, residential customer labels are constructed from sociological characteristics, residential characteristics and energy use attitudes, and the enhanced FP-growth algorithm is employed to investigate any potential links between each factor and the stability of electricity consumption.

Compared with the original FP-growth algorithm, the improved algorithm can realize the excavation of rules containing specific attribute labels, which improves the excavation efficiency. In terms of factors influencing electricity stability, characteristics such as a large number of family members, being well employed, having children in the household and newer dwelling labels may all lead to poorer electricity stability, but residents' attitudes toward energy use and dwelling type are not significantly associated with electricity stability.

This paper aims to uncover household socioeconomic traits that influence the stability of home electricity use and to shed light on the intricate connections between them. Firstly, in this article, from the perspective of electricity stability, the characteristics of the power consumption of residents' users are refined. And the authors use the entropy weight method to comprehensively evaluate the stability of electricity usage. Secondly, the labels of residential users' household characteristics are screened and organized. Finally, the improved FP-growth algorithm is used to mine the residential household characteristic labels that are strongly associated with electricity consumption stability.

1. The stability of electricity consumption is important to the stable operation of the grid.

2. An improved FP-growth algorithm is employed to explore the influencing factors.

3. The improved algorithm enables the mining of rules containing specific attribute labels.

4. Residents' attitudes toward energy use are largely unrelated to the stability of electricity use.

This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.

This cross-sectional study was conducted with 562 45–64-year-old postmenopausal women who presented to a Family Health Center. To collect the data, the Descriptive Information Form and Food Frequency Questionnaire were used. In the data analysis, numbers, percentages, mean, standard deviation and multiple linear regression analysis were used.

The multiple linear regression analysis demonstrated that dietary putrescine intake was negatively associated with systolic blood pressure (ß = −0.179, p < 0.001), dietary spermidine intake was positively associated with waist circumference (WC) (ß = 0.142, p = 0.013), systolic blood pressure (ß = 0.188, p = 0.001), diastolic blood pressure (ß = 0.218, p < 0.001), body mass index (BMI) (ß = 0.169, p = 0.003) and waist-to-height ratio (WHtR) (ß = 0.156, p = 0.006), and dietary spermine intake was negatively associated with WC (ß = −0.158, p = 0.003), systolic blood pressure (ß = −0.195, p < 0.001), BMI (ß = −0.107, p = 0.042) and WHtR (ß = −0.138, p = 0.009).

Owing to the study’s cross-sectional nature, the lack of succession in the cause–effect relationship, the use of self-report Food Frequency Questionnaire to determine dietary polyamine intake and the inability to analyze seasonal differences are among the limitations of the study.

In this study, an association was determined between dietary polyamines, metabolic risk parameters and anthropometric measurements. The findings suggest that dietary polyamines in human health should be further investigated owing to the increasing metabolic risk parameters.

Globally, the oil and gas (OG) industries are under pressure from numerous stakeholders for their sustainable operations against the backdrop of climate change, ecological damage and social challenges. Drawing on the twin theoretical frameworks of the institutional theory and dynamic capability perspective, this study aims to examine the impact of the institutional pressures and dynamic capabilities on the overall sustainability performance of OG industry.

This study uses survey method to analyze the responses from 275 middle management professionals of OG industry in India using partial least squares structural equation modeling. Further, focused group discussions with the select industry leaders validate the empirical findings of this study.

The research reveals that both institutional pressures and firm’s dynamic capabilities have significant positive impact on its economic and environmental performances in OG sector in India. However, they do not have any impact on social performance, unlike earlier findings.

The main limitation of the study is generalizability of the findings, given the cross-sectional design of the study.

Insights of this study will help regulators and policymakers in formulating effective regulatory and policy frameworks, besides creating awareness amongst the organizations to simultaneously focus on all the three aspects of sustainability performance.

The research has bearing on policy formulation and creating a regulatory ecosystem to ensure overall sustainability performance of OG industry in India.

Researchers in the field recognize the importance of the relationship between contractor and contractee in the process of information technology (IT) outsourcing. However, little is known about the impact of the manager's profile in this process. Thus, the objective of this research was to analyze the impact of the perception of competence, autonomy and relationship of public managers on relational governance (RG), as well as, to identify the effect of perceived control in this relationship.

This study uses a quantitative approach to investigate the impact of the behavioral characteristics of IT managers from the self-determination theory (SDT). The data were collected in Brazilian public institutions active in the areas of education, finance, statistics and technology, and the hypotheses were identified and evaluated using the technique of partial least squares structural equation modeling (PLS-SEM).

The results identified that managers' self-determination is related to the perception of control, which, consequently, impacts the RG by providing feelings of competence and autonomy capable of building a beneficial relationship with the IT provider.

This study promotes the understanding that upper management needs to support the autonomy of managers to increase their levels of intrinsic motivation when managing supplier deliveries.

The application of SDT to the IT outsourcing context provides new insights into the mediation of perceived control by explaining the relationship between managers' expectations and motivations as an important driver for RG.

Los investigadores en la materia reconocen la importancia de la relación entre contratista y contratado en el proceso de externalización de las tecnologías de la información (TI). Sin embargo, poco se sabe sobre el impacto del perfil del gestor en este proceso. Así, el objetivo de esta investigación fue analizar el impacto de la percepción de competencia, autonomía y relación de los gestores públicos en la gobernanza relacional (GR), así como, identificar el efecto del control percibido en esta relación.

Este estudio utiliza un abordaje cuantitativo para investigar el impacto de las características de comportamiento de los gestores de TI a partir de la teoría de la autodeterminación (TAD). Los datos fueron recolectados en instituciones públicas brasileñas que actúan en las áreas de educación, finanzas, estadística y tecnología, y las hipótesis fueron identificadas y evaluadas utilizando la técnica de modelado de ecuaciones estructurales por mínimos cuadrados parciales (PLS-SEM).

Los resultados identificaron que la autodeterminación de los directivos está relacionada con la percepción de control, en consecuencia, repercute en el GR al proporcionar sentimientos de competencia y autonomía capaces de construir una relación beneficiosa con el proveedor de TI.

Este estudio promueve la comprensión de que la alta dirección necesita apoyar la autonomía de los directivos para aumentar sus niveles de motivación intrínseca a la hora de gestionar las entregas de los proveedores.

La aplicación de la teoría de la autodeterminación al contexto de la subcontratación de TI proporciona nuevos conocimientos sobre la mediación del control percibido al explicar la relación entre las expectativas y motivaciones de los directivos como un importante impulsor de la GR.

Equipment performance helps the manufacturing sector achieve operational and financial improvements despite process variations. However, the literature lacks a clear index or metric to quantify the monetary advantages of enhanced equipment performance. Thus, the paper presents two innovative monetary performance measures to estimate the financial advantages of enhancing equipment performance by isolating the effect of manufacturing fluctuations such as product mix price, direct and indirect characteristics, and cost changes.

The research provides two measures, ISB (Improvement Saving Benefits) and IEB (Improvement Earning Benefits), to assess equipment performance improvements. The effectiveness of the metrics is validated through a three stages approach, namely (1) experts' binary opinion, (2) sample, and (3) actual cases. The relevant data may be collected through accounting systems, purpose-built software, or electronic spreadsheets.

The findings suggest that both measures provide an effective cost–benefit analysis of equipment performance enhancement. The measure ISB indicates savings from performance increases when equipment capacity is greater than product demand. IEB is utilised when equipment capacity is less than product demand. Both measurements may replace the unitary cost variation, which is subject to manufacturing changes.

Manufacturing businesses may utilise the ISB and IEB metrics to conduct a systematic analysis of equipment performance and to appreciate the financial savings perspective in order to emphasise profitability in the short and long term.

The study introduces two novel financial equipment performance improvement indicators that distinguish the effects of manufacturing variations. Manufacturing variations cause cost advantages from operational improvements to be misrepresented. There is currently no approach for manufacturing organisations to calculate the financial advantages of enhancing equipment performance while isolating production irregularities.

This study aims to create a more humane and responsible workplace, individuals’ gratitude and meaningfulness seem of utmost importance. This study is an effort to understand the role of gratitude intent of potential managers.

This study examines the psychological characteristic of business students in India. The researchers surveyed 333 Indian students as future managers. The collected data has been analysed with the Smart PLS 3 version to assess the formative-reflective scale by comparing model fit, measurement model and structural modelling.

The results establish that gratitude significantly affects the life satisfaction of future managers. Findings also show that materialism is negatively related to life satisfaction and meaningfulness. The importance–performance map analysis finding suggests that meaningfulness in life is a potential indicator of life satisfaction for the population studied.

Due to the limited research available on the psychological underpinnings in the Indian context, there is a massive value in examining how materialism and gratitude concurrently and distinctively predict meaning in life and the life satisfaction of future managers. This paper gives a formative explanation of the model consisted gratitude, materialism and meaningfulness in life on the life satisfaction of future managers. This study establishes the importance of meaningfulness of life in attaining life satisfaction for young managers.
