Lean Six Sigma (LSS) is a continuous improvement methodology used to increase the efficiency and effectiveness of processes. Although there are several articles published, only two have analyzed the literature from a bibliometrics perspective. The purpose of this paper is to analyze the LSS literature by bibliometrics, identifying its state of the art, scientific gaps and research trends.

Articles published up to 2016 in the database Scopus were investigated to identify the most significant articles, authors, journals, institutions and countries based on citation counting as well as the most frequent keywords and subject areas on LSS. Articles published in 2014, 2015 and 2016 were analyzed to point out scientific gaps and to identify eight main research trends on LSS.

The research trends are: “LSS implementation”, “Healthcare”, “LSS tools”, “Human factors”, “Expansion of results”, “SME”, “LSS combined with other methodologies” and “Education”. The research outcomes also point out the most significant articles, authors, journals, institutions and countries in LSS literature.

This research contributes to develop the state of the art of LSS and helps professionals as well as researchers to identify which issues new studies should address.

The performance of the literature is measured based on the number of citations and not on the number of published papers, and the bibliometric analysis covers the highest number of articles so far (319 articles). Besides, the identification of the main research trends on LSS is exclusively based on the most recent studies.

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.

The purpose of this paper is to propose an initial step for understanding the sensory perception and purchase intent of Brazilian olive oil consumers. It also investigates the sensory perception and purchase intent for a Brazilian-made olive oil.

The sample, consisting of 115 surveyed consumers, is described demographically. The aspects related to sensory analysis and purchase intent associated with the key attributes indicated by the consumers are then discussed. Finally, consumer segmentation is carried out to characterize the consumers in more detail, in terms of both demographic and predictive variables for olive oil consumption.

Consumers displayed a sensory perception that is coherent with olive oil characteristics, thus being able to distinguish three different olive oils from a compound oil sample. Regarding purchase intent and preference, consumers showed mixed behaviors, which was not entirely convergent with the identified sensory aspects. Therefore, it was possible to segment them into three distinct groups: utilitarian, naïve, and expert consumers.

Brazil is an emergent olive oil market, which can create both research and business opportunities for the country. This preliminary study contributes to the advancement of this research subject in the non-traditional markets for olive oil.

The set of services provided by the mobile phone platform, is becoming increasingly complex and requiring more computing power, hence higher energy consumption, and compromising the autonomy of these devices. The purpose of this paper is to identify scenarios where methods could be applied to reduce such consumption and extend the mobile autonomy.

This mobile evolution has given rise to a lot of energy saving research activities, which mainly focus on the hardware side of computational systems. However, it is tempting to suppose that only hardware dissipates power, not software. This paper characterizes several hardware and software scenarios, which could be explored to develop energy‐efficient mobile techniques.

From this analysis, the authors argue that the development of applications that consider energy saving as one of their requirements, can result in a significant final energy saving because solutions will be part of their own software and they do not depend on external resources to obtain a lower consumption.

This paper provides a broad analysis about the different research directions in energy consumption optimization and stresses the important contributions that the software engineering area could offer to this subject.

Drawing on an ethnographic research study, developed in three different food assistance initiatives (FAIs) operating in Portugal, this article seeks to explore the elements that characterize them and the main organizational challenges they face.

Participant observation was carried out in a surplus food redistribution charity, a soup kitchen and a social supermarket, and semi-structured interviews were conducted with supervisors of these FAIs. The study followed an inductive coding strategy, and a thematic analysis was developed.

The main results point to an appreciation of the initiatives and the role they play, but they also highlight the existence of several challenges, mainly related to: 1) difficulties in accessing sources of funding, 2) the absence of an intervening state and 3) a scarcity of resources that allow a thorough assessment of their activities and services provided, which weakens the public image of these responses.

The development of food assistance in Europe has a long history. Over the past few years, this sector has grown significantly. Nowadays, it is possible to identify several realities around emergency food provision. However, this heterogeneity has not been sufficiently explored in the literature. In addition, there are few studies that report on the variety of initiatives that coexist in Portugal and establish a comparison between them. The current paper intends to overcome this gap by seeking to understand the main models of food assistance operating in the country.

The purpose of this paper is to identify and analyze the literature related to accounting and auditing services quality.

The authors performed a systematic literature review that considered 22 papers on the topic. The authors also applied a bibliometric analysis in order to identify the main characteristics of these studies to discuss and provide research opportunities in this field.

The bibliometric results indicate that most papers were published in services and marketing journals. The accounting service quality theme has been rarely researched in accounting field. In addition, based on our review, it was possible to identify that most papers use quantitative methods, such as surveys. The papers' conclusions diverge from each other, demonstrating a still fragmented literature.

Taken together, the paper shows how accounting services quality is relevant and emerging topic that demands future research about accounting professionals' skills, their activities and how their customers perceive quality in an environment of constant change.

The analyses indicate that there are six broad areas for future research on this topic: successes and failures of accounting services providers; the role of “client centricity”; digital accounting services; services quality and accounting education; services quality when considering different types of accounting and auditing services and development of a measurement scale and a theoretical model for accounting services quality. This paper contributes for the ongoing debate about how competition, technology and innovation are changing the landscape for accounting and auditing services providers.

Some universities have a commitment to both academic education and sustainable development, and the sustainable development goals can support several sustainable actions that universities may take as principles and attitudes. From this perspective, the purpose of this study is to present environmentally sustainable practices at a federal university in Brazil and to analyze and discuss the potential environmental impacts associated with an environmentally sustainable practice implemented using life cycle assessment (LCA) and its benefits for the university’s decision-makers.

To accomplish that, the study combines a description of environmentally sustainable practices at the 13 campuses of the Universidade Tecnológica Federal do Paraná (UTFPR) in terms of education, water and electricity consumption, waste management and emissions. As a result of this analysis, one campus identified that a high volume of disposable plastic cups were being disposed of, for which the use of reusable plastic cups was introduced. In addition, an LCA study (ISO 14040:2006 and 14044:2006) quantified the benefits of the introduction of said reusable plastic cups.

The results show that the university is working on environmentally sustainable initiatives and policies to become greener. At the same time, using a systematic LCA made it possible to measure that replacing disposable plastic cups for reusable ones reduced waste generation but increased water consumption on the campus. Faced with this, a sensitization was carried out to reduce water consumption. Finally, the current study provides lessons on the environmental performance to universities interested in sustainable practices, fostering perspectives for a better world. The findings of this study encourage organizations to accomplish environmental actions toward greener universities. The study shows that institutions need to be reflective and analytical about how even “greening” measures have impacts, which can be mitigated if necessary.

The sustainable practical implications were reported, and an LCA was conducted to assess potential environmental impacts of reusable plastic cups. It was identified that raw material production is the phase that generates most environmental impacts during the life cycle of the product, along with the consumer use phase, due to the quantity of water used to wash the reusable cups. In addition, the practical contributions of this study are to provide insights to institutions that aim to use environmental actions, i.e. suggestions of sustainable paths toward a greener university.

This is one of the first studies to investigate and discuss sustainable practices at UTFPR/Brazil. The study assessed one of the practices using a scientific technique (LCA) to assess the impacts of reusable plastic cups distributed to the students of one of the 13 campuses. Although there are other studies on LCA in the literature, the value of this study lies in expanding what has already been experienced/found on the use of LCA to assess environmental practices in university campuses.
