The purpose of this paper is to examine how both offenders and their families perceived their interactions with police and whether there were negative consequences of the offender-focused strategy that was implemented in a hot spots policing experiment.

Data from interviews of 32 offenders and 29 family members are examined qualitatively for themes to evaluate how the strategy was carried out and how it impacted offenders’ behavior and both groups’ perceptions of the police detectives and the strategy overall.

The results show that there was overwhelming agreement by both offenders and their family members that the police detectives who contacted them treated both groups with dignity and respect. After the contact was over, the offenders appeared to commit less crime, followed probation more closely, and had positive feelings about what the police detectives were trying to do. Improvement of the offenders’ relationships with their families was an unanticipated finding indicating a diffusion of benefits of the strategy.

The results suggest that when procedural justice principles are used in an offender-focused police intervention, positive impact can be achieved without negative consequences.

This is a rare example of an in-depth evaluation of the perceptions of offenders and family members contacted through a hot spots policing offender-focused strategy.

The native species from western Mato Grosso do Sul provide fruits with unique sensory characteristics and high nutrient concentrations. Tropical fruit consumption is increasing due to the growing recognition of the nutritional value. These fruits play important roles through the marketing of their products and nutritionally through their consumption. All fruits are edible and are used in the food industry and well sensory accepted. The purpose of this paper is to verify the physicochemical characteristics, bioactive compounds and antioxidant activity in fruits collected in the Cerrado and Pantanal biomes from western Mato Grosso do Sul.

The fruits of baru, bocaiuva, jatobá, jenipapo and pequi were collected. To characterize them, longitudinal diameter, transverse diameter, total soluble solids, acidity, pH, ascorbic acid, total phenolics, antioxidant capacity, total sugar, glucose and macro and micronutrient contents analysis were performed in triplicate.

Jatobá presented the highest values of vitamin C. For phenolics, baru and jatobá stood out; bocaiuva presented the highest results for sugars, while jatobá was superior for glucose. The fruits with the highest antioxidant capacity, DPPH, were pequi and baru, while via ABTS the jatobá was the highest. Baru presented higher levels of nitrogen, phosphorus, magnesium, copper, zinc and iron. The bocaiuva presented the highest results for potassium and sulfur, the jatobá calcium and manganese. Jenipapo stood out with its boron content. Magnesium presented superior results in the baru, jenipapo and bocaiuva. The results reinforce the diversity of physicochemical characteristics.

The increase of the flow of available information, together with the growth of multicultural influences, the search for wholesome diet and the diversity of flavors and colors make these fruits important regional development tools. Their characteristics encompass national and international exploration potential that arouse consumer interest and contribute to the pursuit of innovations. In addition, the native species mentioned above provide fruits with unique sensory characteristics. Their consumption is increasing in the markets due to the growing recognition of their nutritional value. Therefore, these fruits play important roles, economically, through the marketing of their products and nutritionally through their consumption.

The purpose of this paper is to investigate the impacts of left Brazilian political parties and partisan disruption on the homicide rate in Brazil.

The authors use panel data for the states between the years 1980 and 2011. The database used is an unbalanced panel covering a sample of 27 Brazilian states over 32 years, 1980-2011, totaling about 855 observations.

It is estimated that these two political factors are sources that have connection to the increased level of violence in Brazil. These analyses provide several important results. First, partisan disruption is associated with a higher homicide rate, compared to non-partisan disruption. The results from the panel also suggest that left-parties in government have a positive impact on homicide, compared to non-left-parties.

Information regarding premeditated homicides (CID-BR-9 database) is available for all Brazilian states, and may be tabulated from the same micro-data at any level of aggregation. Some of the well-known problems regarding the choice of this variable are as follows. First, deaths resulting from wounds are sometimes included in the statistics whether wounds were intentionally inflicted or not. In addition, some incidents end up not being registered because certain deaths are not reported. This tends to occur more frequently in rural areas. Fortunately, this second problem does not appear to be too significant, as under-registry of deaths due to external causes is much lower than the amount resulting from natural causes (see, e.g. Cano and Santos, 2000). In addition, this problem may be controlled if under-registry remains stable over time by applying fixed effects to the panel data.

The main Brazilian political parties diverge on the causes of crime and how criminals should be punished. For example, in Brazil, the minimum age for one individual to be punished with imprisonment is 18 years old. Practices crimes for young people between 12 and 18 implies only in socio-educational measures. Given the high level of violence in Brazil, there is a bill being debated in the parliament that proposes to reduce the age to 16 years. Based on the research, 90 percent of the population approves the reduction of age to 16 years. However, the majority of parliament is opposed to changing the law. In general, the more conservative parties are favorable to changing the law.

These divergent postures can be associated with the ideological essence or to belief system of each political party. Political parties have the potential capacity of changing crime trends through economic and social policies as well as by applying stronger sanctions against crime. Given the law enforcement system, the cycle of crime in Brazil may be related to the profile of the political party elected.

The authors assume the hypothesis that the current Brazilian multi-partisan system has an incentive system in which politicians do not respond adequately to the basic wishes of voters. Among such desires, the authors emphasize public safety. This paper evaluates the empirical effect of partisan disruption on homicide rate.

The objective of this study was to elaborate and characterize formulations of type mortadella bologna in an industrial unit.

Two formulations (Formulation 1 – F1 and Formulation 2 – F2) were characterized at a storage stability of 22 ºC for physicochemical (pH, a_w, moisture, protein, fat and lipid oxidation: TBARs and peroxide index, nitrite/nitrate, texture and thermal analysis: TG), sensory (acceptability), microbiological (Clostridium reducing sulfite, Streptococcus, Salmonella sp., mesophilic and coliform thermosensitive) and histological (organization and tissue distribution) characteristics.

In relation to the water activity (a_w), the formulation F2 presented a value of 0.925 as well as the lower TBARs (0.19 mg MDA/kg) and greater hardness (3945.47 gf), 85% acceptance index and greater mass loss by thermal analysis after 60 days of storage. The multivariate analysis showed that the hardness presents negative correlation in relation cohesiveness, resilience and a_w. There is also a strong positive correlation of the cohesiveness in relation to the resilience and a_w. In addition, moisture has a high positive correlation with TBARs, peroxide index, a_w, L* and texture parameters (adhesiveness, cohesiveness and resilience).

Therefore, the importance of the elaboration process of emulsified meat products was emphasized, aiming to add value and guarantee food safety, taking into account the current legal aspects.

The purpose of this paper is to propose a competitiveness measurement system for start-ups considering multiple critical success factors.

The methodological approach uses concepts from key performance indicators (KPIs) and multi-criteria decision analysis (MCDA) based on the fuzzy AHP (FAHP) methodology to weight the criteria related to fundamental points of view (FPVs) and critical success factors (CSFs).

Data collection was performed with 21 specialists and 28 start-ups, which returned the weights and performance of CSFs and FPVs related to the start-ups’ competitiveness. The results show only one start-up had a highly competitive global performance. In addition, all start-ups showed low competitiveness related to industry 4.0 technologies.

The article collaborates with existing research as a starting point for discussions on the subject, considering that previous research did not address the measurement of the start-ups’ competitiveness level through multiple factors, as developed in this article. In addition, we provide decision-makers and other stakeholders in the start-up ecosystem with a robust measurement system to assess business competitiveness and diagnose the company’s situation.

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.

This study aimed to identify the potential for economic activities related to the ocean economy in Brazil to become blue economy (BE) activities, in which the concept of the Sustainable Development Goals (SDGs) is central.

To achieve the aim, the authors collected information on the SDGs and estimated data from the ocean economy sectors for the 256 Brazilian coastal cities. The authors predicted the indices for potential development of territories and sectors in the BE using two parameters: employed persons (EP) and sectoral added value (AV).

The results show that the capitals of coastal states present the highest potential indices for the BE, especially Rio de Janeiro, which accounted for 83.3% of sectoral added value in the Brazilian ocean economy with potential for sustainable development and generated 107,800 active formal jobs (26.9% of the country's total). In addition, restaurants, hotels and similar establishments are, on the Brazilian coast, the most frequent on the coastal zone and have the highest potential for BE activities.

Regarding its contributions, this research innovates by developing an indicator that can help stakeholders understand the similarities and differences between cities and regions, whether through a social, economic, or environmental lens. Therefore, by following this methodological path for measuring the BE, viewing the distinct patterns of sustainable development by area is possible, thereby supporting action plans for the fulfillment of the 2030 Agenda and the implementation of a marine spatial planning process for the country in the context of the Ocean Decade (2021–2030).

Why do some individuals become entrepreneurs while others do not? This fundamental question has vexed entrepreneurship scholars for some time, giving rise to various schools of thought. Traditional economic motivation theories, for example, suggest that entrepreneurial opportunities arise from changes in either supply (Shane, 2000) or demand (Dew et al., 2004) and emphasize personal economic gain as a motivator for pursuing entrepreneurship. Both neoclassical equilibrium and psychological theories take a person-centric perspective whereby stable, enduring differences among people’s characteristics, determines who becomes an entrepreneur. Opportunity recognition may be enhanced through perspective taking (i.e. putting oneself in the shoes of another person) (Prandelli et al., 2016).

The founders of the company provided us with access to the inner workings of the company, their mentors and advisors and themselves. This study used archival research and interviews when preparing this case. Interviews allow for the development of uncensored, real-life insights into the entrepreneur’s business experience. The authors first conducted a 90-min interview with Rajia and Ray at DifferenceMaker^® Central on the UMass Lowell campus. DifferenceMaker^® provided us with pictures and timelines from when Rajia and Ray participated in the various DifferenceMaker^® activities and competitions. A follow-on 90-min interview was conducted with the founders four months later at the UMass Lowell Innovation Hub to delve deeper into their transition from engineers to entrepreneurs.

In the summer of 2016, the future of invisaWear suddenly became uncertain. Rajia Abdelaziz and Ray Hamilton had conceived an idea for smart jewelry that they felt solved a real problem. But it was one thing to have a great idea and quite another to turn that idea into a real business. As engineering students, they were accustomed to solving problems, but if they truly wanted to make an impact, they had to learn to solve problems as entrepreneurs. With the help of DifferenceMaker^® and their mentors, they developed an entrepreneurial mind-set and decided to build invisaWear into a company.

This case is suitable for an undergraduate course in business or entrepreneurship. This case is intended to illustrate to both business and non-business students how individuals with different backgrounds can become entrepreneurs. Presented as a real-life example of how engineering students can make the transition to an entrepreneurial mind-set, the case can also be used to hone in on select topics including opportunity recognition, problem-solving, ideation and the business model canvas.

Given the current challenges for improving the tribological behavior in automotive engines, which require lubricants that adapt to different operating conditions through replacement mechanisms to reduce friction and wear, this study aims to analyze the use of hexagonal boron nitride nanoparticles blended in the lubricating oil of a diesel engine. The target was to minimize frictional power losses and wear of cylinder liner surfaces to validate what was observed in laboratory and to confirm improvements in thermal efficiency.

Before the definition of the concentration to be used in a real engine environment, tests of sample dispersion were conducted using an ultrasound bath. The mixtures were added to storage bottles in concentrations of 0.1% and 0.5%, as observed in Figure 1. The samples were subsequently analyzed using the dynamic light scattering (DLS) technique. There was a reduction in the hydrodynamic size for the sample with 0.5% of hexagonal boron nitride (hBN), possibly due to sedimentation of the powder during the analysis, which supported this work to continue with the use of 0.1% concentration.

The behavior of hBN as nano additive in a real diesel engine was problematic when compared with laboratory environment, leading to impact in oil temperature. In addition, it was noticed a high amount of deposit formation at the top dead center (TDC) and mid-stroke (MC) and nonsignificative wear at MC and bottom dead center (BDC) of the cylinder, with unusual formation of products from antiwear additives known as zinc dialkyl-dithiophosphate at MC position with the use of hBN. For this reason, this work provides insights into how hBN nanoparticles may not contribute toward the improvement of tribological performance.

The findings of this work aimed to provide a better understanding of the impact of hBN nanoparticles used as additives in real engine environment in terms of performance and tribological impacts. The results of this work indicated that hBN as additive gave poor results in terms of performance and wear prevention.

Smart campuses can be seen as the future of higher education efforts, especially for their contributions to sustainability and to encourage innovation. This paper aims to present the benefits of smart practices in a Higher Education Institutions and highlights its connections to the sustainable development goals (SDGs).

The methodology is divided into three steps: first, an international search and assessment of smart practices at universities; second, the identification of smart practices in a university campus in southern Brazil; and third, the presentation of the benefits of smart practices and their relationship with the SDGs.

The results showed that globally, the area most covered by smart practices in universities is the environment and, specifically, focused on waste reduction. in the context of this case study, the benefits of implementing smart practices mainly reach SDGs 4 and SDG 9, especially due to aspects of teaching technologies for the new classroom models and the optimization of campus infrastructure management.

The study encourages other universities to implement smart practices in their campuses, to becoming smart campuses while they also collaborate in achieving the SDGs while raising the discussion on the importance of committed actions taken on a university campus with the UN SDGs, to leverage synergies on campus operations at universities.

This paper presents a set of smart practices that universities are applying both globally and locally (in southern Brazil). In addition, it contributes to sustainability research by showing how smart practices have the potential to promote SDGs in universities, especially through campus operations.
