Robotic Applications

The development of robotic systems to operate in forest environments is of great relevance for the public and private sectors. In this sense, this article reviews several scientific papers, research projects and commercial products related to robotic applications for environmental preservation, monitoring, wildfire firefighting, inventory operations, planting, pruning and harvesting. After conducting critical analysis, the main characteristics observed were: (a) the locomotion system is directly affected by the type of environmental monitoring to be performed; (b) different reasons for pruning result in different locomotion and cutting systems; (c) each type of forest, in each season and each type of soil can directly interfere with the navigation technique used; and (d) the integration of the concept of swarm of robots with robots of different types of locomotion systems (land, air or sea) can compensate for the time of executing tasks in unstructured environments. Two major areas are proposed for future research works: Internet of Things (IoT)-based smart forest and navigation systems. It is expected that, with the various characteristics exposed in this paper, the current robotic forest systems will be improved, so that forest exploitation becomes more efficient and sustainable.

Support Tools

The second half of the 20th century was characterized by rapid growth of the urban population and lack of attention to environmental quality in the urbanizes territories. Thus, the development of many cities during that period took place through policies which, over time, resulted in a disaggregated landscape, both in morphological and functional terms. In some cases, these policies have caused the creation of land portions without a specific characterization, and the generation of urban voids that negatively affect the city’s development. To solve this problem, the public administration sectors of many countries are looking for new intervention strategies that are feasible from a social and economic point of view which are able to guarantee sustainable development. From this perspective, the execution of urban regeneration initiatives, including forestation, allows for the improvement of both environmental quality and citizens’ well-being, and promotes economic development. Considering the multiple effects that these initiatives can generate and the limited availability of public and private resources, it is appropriate to use multi-criteria decision support tools through which it is possible to evaluate the interventions’ complexity and best identify the city areas that lend themselves to be recovered and improved through the forestation. The aim of this work is to develop a support tool for public administrations aimed at identifying the optimal forestry projects’ location according to criteria that not only refer to financial type, but also their social, cultural, and environmental nature. Using Discrete Linear Programming algorithms, the model has been tested through a theoretical case study and reveals the advantages and limitations of the model, as well as future research prospects.

The analysis of development of innovation in services starts from the interaction of different actors. This research aimed to identify the dynamics of the mobilization of preferences and capabilities of different actors (political decision-makers, users and servers) in the development of the final characteristics of the service and, consequently, of the innovation in the public health context of a municipality located in the south of Brazil. Was carried out analysis of data from descriptive and inferential statistics of case study. The main results highlight the preponderance of the operation of server capacity for mobilization of different types of innovation, and consequently the production of the final characteristics of the health service. In this context, service innovation can finally be taken as the endogenous decision-making process of the organizations that make up the sector and that derive from the very nature of health services. Finally, we described the limitations and future research opportunities.

The Status

Laws such as the Americans with Disabilities Act of 1990 (ADA), as well as subsequent legal sanctions, appear to have had limited success in substantially increasing the number of persons with disabilities within the employment context. Therefore, it is critical that a better understanding be developed of both the physical and attitudinal barriers persons with disabilities face with regard to gaining such employment. The present study was conducted to examine how the origin of an applicant's disability, the status of the job being applied for, and the level of test accommodation to be provided influenced perceptions of what was a reasonable pre-employment testing accommodation. Human resources testing professionals from both the public and private sectors rated how reasonable they perceived a variety of testing accommodations to be. The results reveal that origin of disability, job status, and level of accommodation all affected how reasonable a given testing accommodation was perceived to be and that there was significant interaction effects for all three factors. The results of this study also support Stone and Colella's model of the complex nature of workers' reactions to individuals with disabilities in organizations. The implications of the study, as well as needs for future research, are also discussed.

Purpose – In order to address a notable gap in the research literature, the purpose of this paper is to examine age-related differences in juvenile homicide perpetration. Design/methodology/approach – Data on 150 juvenile homicide offenders and their offences was derived from material available within the public domain, including media reports, case studies, court reports and previously published studies. Comparisons were then made between those aged 14 and under (n=63) and those aged 14-17 (n=87) across a range of offender, victim and offence-related variables. Findings – There were no significant differences between the child (U-14) and adolescent (14-17) offender samples on any of the measured variables. The two groups had similar backgrounds, selected similar types of victims, had comparable breakdowns of different types of victim-offender relationship and had similar patterns of weapon use. Research limitations/implications – The fact that the two groups did not differ significantly has notable implications in practical and applied domains. By identifying risk factors for juvenile homicide perpetration, findings open up a range of possibilities for identification, investigation and intervention. In addition, findings might inform the development of offender treatment and rehabilitation programmes. Key limitations relate to the quality and quantity of data employed. Ways of remedying these weaknesses in future research are addressed. Originality/value – This is the first study to directly compare child and adolescent perpetrators of homicide over a broad range of offender, victim and offence attributes.

The foundational goal of civil rights legislation is to reduce discrimination, in both the public and private sector. To understand the levels of perceived discrimination in the federal government, this research note examines 9 years of data reported under the requirements of the Notification and Federal Employee Antidiscrimination and Retaliation Act of 2002 (No FEAR Act). From 2006 to 2014, less than 1% of federal employees filed discrimination complaints each year, and the discrimination complaint rate did not significantly change over the time period. Race, color, and national origin were the most frequently claimed discrimination bases. Approximately half of all complaints alleged retaliation after filing an initial discrimination claim. In addition, federal employees most frequently claimed that discrimination occurred in the context of nonsexual harassment. This research note describes other trends in discrimination claims and proposes directions for future research.

AbstractThe present research examined the perceptions of Australian employees on dimensions of workplace stress. The sample included 664 male (n= 234) and female (n= 430) workers from the public (n= 559) and private (n= 105) sectors. Participants completed the Health and Safety Executive Indicator Tool as a measure of workplace stress. Results indicated that private sector employees rated their employers as being more effective in managing workplace stress, while employees in both sectors rated their employers as less effective in managing Job Content stressors than Job Context stressors. Compared with normative benchmarks, employees overall also reported risks of stress associated with Relationships and Role. Implications of these findings and suggestions for future research were discussed.

Public Versus Private

The effects of supervisor gender and work environment (public versus private sector) on supervisors' attitudes toward older employees were investigated. Participants attending a supervisory development institute completed questionnaires relating to performance appraisal practices in the public and private sectors. As part of this larger study, 120 participants were selected at random and combined in a balanced, 2 × 2 factorial ANOVA. Two independent variables — supervisor sex and type of work environment — were manipulated to assess their effects on supervisors' attitudes towards older employees. A significant main effect was found for type of work environment, confirming the hypothesis that public sector supervisors were more lenient in their evaluations of older employees. A main effect was also found for supervisor gender, but not in the predicted direction. Female supervisors were found to be more unfavorable in their evaluations of older employees. No interaction was found. Implications of findings and suggestions for future research are offered.

Purpose – The purpose of this paper is to understand the development of good governance research worldwide covering the practices by the public and private institutions. Design/methodology/approach – A bibliometric study on 3,375 scientific papers from 1990 to 2018 was conducted, and the data was analyzed to examine the trends and challenges in the worldwide scientific productions for good governance. Findings – Most research comes from scholars in the high-income countries (70%) and has moved from classical socio-economic topics of good public governance to sustainable environmental development. Post-colonial politics and economy remain unending discussion on good governance in Africa and Asia. Exporting the implementation of good governance from wealthier countries attracts critics and arguments from the third countries. Practical implications – 3,375 scientific papers used in this research was collected from Scopus database. While it was not the only existing scientific research database, the collection could not guarantee the sample adequacy of the worldwide scientific knowledge on good governance. There are papers that are not Open Access (OA), written in other languages, published in regional/national journals, nor have significant academic impact. Originality/value – The authors recognize that this study is the first evaluation ever. The result provides the first scientific reference for probing the worldwide practices of good governance for public and private sectors. Under the changing world environment in the form of digital transformation, the rise of intangible economy, and the worldwide trend of co-existence between nationalism and globalism; this paper can provoke the policymakers to rethink good governance both for public and private institutions.
