The Impact

Graph-based design languages have received increasing attention in the research community, because they offer a promising approach to address several major issues in engineering, e.g., the frequent manual data transfer between computer-aided design (CAD) and computer-aided engineering (CAE) systems. Currently, these issues prevent the realization of machine executable digital design processes of complex systems such as vehicles. Promising scenarios for urban transportation include an interconnection of mass transportation systems such as buses and subways with individual vehicles for the so-called “last mile” transport. For several reasons, these vehicles should be as small and light as possible. A considerable reduction in weight and size can be achieved, if such vehicles are tailored to the individual size, weight and proportion of the individual user. However, tailoring vehicles for the individual characteristics of each user go beyond a simple building set and require a continuous digital design process. Consequently, the topic of this paper is a digital design process of a self-balanced scooter, which can be used as an individual last-mile means of transport. This process is based on graph-based design languages, because in these languages, a digital system model is generated, which contains all relevant information about a design and can be fed into any simulation tool which is needed to evaluate the impact of a possible design variation on the resulting product performance. As this process can be automated by digital compilers, it is possible to perform systematic design variations for an almost infinite amount of parameters and topological variants. Consequently, these kinds of graph-based languages are a powerful means to generate viable design alternatives and thus permit fast evaluations. The paper demonstrates the design process, focusing on the drive system of the respective balanced two-wheel scooter and highlights the advantages (data integration and possibility for machine execution).

The Impact

Consensual union, also known as cohabitation, has become more frequent in recent decades in Brazil and many other countries. In this context, some studies have analyzed the impact of marriage on women's wages. This article analyzes the effects of marital status on Brazilian women's wages by specifically investigating the individual characteristics of these effects using data from the 2000 Brazilian Census Database. This study concludes that wages differ by up to 15 per cent between married and single women and up to 3 per cent between married and cohabiting women.

The Impact

The use of open-plan offices is increasing as they are effective in improving intellectual productivity by fostering a communication among workers. Previous research on the relationship between the indoor sound environment and intellectual productivity has mostly reported the impact of the sound environment on the tasks that individuals work on. However, there has been no research on the impact of sound environment on office spaces where multiple workers are actually working. In this study, we developed a system that can analyze the individual characteristics of workers in relation to the sound environment by simultaneously measuring their evaluation to the sound environment and the sound environment of the office. The system collected workers' evaluation of their impressions to the sound environment through a regular questionnaire using the experience sampling method. At the same time, it measured the sound environment of the office with multiple small measurement devices. The obtained sound environment evaluation data and the acoustic data of the office were stored in a single database. Finally, this system was run in a working environment to evaluate the sound environment on a trial basis.

AbstractThe effect of heated waters from coal-burning power stations on the water parameters and the occurrence of macroinvertebrates depends on the individual characteristics of the river to which the heated waters are discharged. The objective of the study was to assess the impact of heated water from the Ostrołęka Power Station on selected water properties and the macroinvertebrate community in the Narew River. Samples were collected in years: 2013-2016 along two river stretches: upstream and downstream of the canal. The water temperature was higher and the oxygen concentrations were lower at the downstream sites compared to the upstream sites of the canal. The values of conductivity, concentrations of nitrates, phosphates, chlorides and calcium were similar at the sampling sites. A total of 33 families of macrozoobenthos were found. The numbers of families were positively correlated with the temperature and conductivity and negatively correlated with oxygen. The heated waters were found to have no effect on the Shannon-Wiener diversity index. The inflow of heated waters increased the percentage of Gammaridae, represented by species Dikerogammarus haemobaphes (Eichwald, 1841) and decreased the percentage of Chironomidae. The presence of the thermophilous bivalve Sinanodonta woodiana (Lea, 1934) was noted downstream of the canal.

The Impact

Scholars and governments are interested in four sets of questions concerning public opinion on foreign policy and national security policy. First, what do public opinion polls measure? How do citizens, who are generally uninformed about foreign policy and world affairs, form opinions on these matters? Second, how rational is public opinion? Is it stable or volatile? Are opinions coherent? Do opinions plausibly reflect the flow of world events? Third, what factors influence the formation of citizen opinions? Specifically, what is the impact of fundamental attitudes toward war and military force, partisanship, ideology, and gender? Finally, how universal are the determinants of citizen opinion, especially on crucial issues of war and peace? Are the findings in global comparisons the same as those in the American or European contexts? Considerable scholarship has been devoted to these four questions. Scholars now characterize public opinion as rational, in the sense that it is fairly stable, coherent, and responsive to real world events. Attitudes toward war and military force are a major focus of the research literature because many specific policy attitudes flow from fundamental views of war. Gender has also become a major focus of research because many studies find that women are less supportive of the use of military force for most purposes. Finally, scholars are beginning to discover that some opinion patterns are universal across societies, while others are more affected by the individual characteristics of national societies. Studies of global public opinion have expanded greatly, with recent scholarship focusing on global attitudes toward gender equality, immigration, and climate change.

The Impact

Studies on female legislative behavior suggest that women parliamentarians may challenge party cohesion by allying across party lines. In this paper we analyze a specific parliamentary activity – bill co-sponsorship – in the Italian lower Chamber, between 1979 and 2016, as a source of information about MPs’ original preferences to study how gender affects party cohesion. Do women form a separated group in the Italian parliament? On average, are they more or less distant from the center of their parties than men? Does gender affect systematically party cohesion? A principal component analysis of co-sponsorship data allows us to identify the ideal points of all MPs in a multidimensional space for each legislature. Based on these data we estimate the impact of gender on party cohesion at the individual level while controlling for the impact of several other variables of different kind (individual, partisan, and institutional). We find that: (1) on average, women show lower cohesion as a group inside different parties and higher party cohesion than men; (2) the influence of gender on party cohesion is not conditional upon individual characteristics, upon the size and organization of parliamentary parties, and upon the share of women in their parliamentary groups; (3) the different behavior of women MPs may depend on the different patterns of recruitment in the parties.

AbstractThis paper presents a preliminary comparison between the role of computer-aided design (CAD) and sketching in engineering through a case study of a senior design project and interviews with industry and academia. The design team consisted of four senior level mechanical engineering students each with less than 1 year of professional experience are observed while completing an industry sponsored mechanical engineering capstone design project across a 17 week semester. Factors investigated include what CAD tools are used, when in the design process they are implemented, the justification for their use from the students' perspectives, the actual knowledge gained from their use, the impact on the final designed artifact, and the contributions of any sketches generated. At each design step, comparisons are made between CAD and sketching. The students implemented CAD tools at the onset of the project, generally failing to realize gains in design efficiency or effectiveness in the early conceptual phases of the design process. As the design became more concrete, the team was able to recognize clear gains in both efficiency and effectiveness through the use of computer assisted design programs. This study is augmented by interviews with novice and experienced industry users and academic instructors to align the trends observed in the case study with industry practice and educational emphasis. A disconnect in the perceived capability of CAD tools was found between novice and experienced user groups. Opinions on the importance of sketching skills differed between novice educators and novice industry professionals, suggesting that there is a change of opinion as to the importance of sketching formed when recent graduates transition from academia to industry. The results suggest that there is a need to emphasize the importance of sketching and a deeper understanding as to the true utility of CAD tools at each stage of the design process.

ABSTRACTThis study examined the impact of situational and individual characteristics on sales representatives' propensity to lie or to tell the truth. The situational elements were the honesty of the organisation climate and its formal rules about lying to customers. The individual elements were the participants' degree of Machiavellianism and tolerance for ambiguity. The results indicated that more Machiavellian people were more likely to lie and that they were less guided by the rules than people who were low in this trait. In addition, rules and climate work together for people with a high tolerance for ambiguity in a complex manner.

The article devoted to one of the topical problems of penitentiary institutions – the return to society of a prisoner who has served a sentence, provided that he or she will never commit crimes. This is the most difficult problem that arises in the course of the implementation by the penitentiary system of its main function – to ensure the safety of society. In many countries, the degree of prisoners’ isolation is determined by their categorization. German practice is based on a risk assessment of illegal conduct in relation to a particular person. The risk of violent acts is not necessarily related to the nature of the committed crime or the length of the sentence. The prison administration makes its own decision on the choice of the regime of detention. The penitentiary system (not the court) develops flexible security measures that can be changed in relation to the prisoner’s personality. All measures taken against prisoners should be based on the proportionality principle. The analysis of various rehabilitation programs for prisoners, used in Western Europe, leads the author to the conclusion that the most effective of them is individual therapy, which reduces the risk of recidivism by almost half. As a standard used in Germany, the author specify the principle of “risk – need – quick res-ponse”. The higher the risk of recidivism, the more intense the impact on the prisoner’s behavior should be. However, the application of this principle will be effective only when the selected cognitive techniques and practical training technologies coincide with the individual characteristics and the prisoner’s ability to learn. In addition, the results achieved by the prison administration must be supported by post-penitentiary rehabilitation programs. The article also describes the system of selection and training of prison personnel in Germany.

Creative Team

Rather than the view of the entrepreneur as a ‘lone ranger’, recent work has focused on the importance of teams in bringing a start-up to growth and success. Here, we aim to bridge the gap between the individual characteristics of entrepreneurs and the characteristics of their teams by examining openness of founders in relation to creative team environment (CTE), innovative work behaviour (IWB) and performance. On the basis of upper echelon theory and integrating other complementary theories such as the attention-based view, we develop a theoretical framework and test this using a survey of 322 high-tech entrepreneurs. Our findings suggest a mediating role of CTE and IWB in the relation between openness of entrepreneurs and performance. The implications of the results for managerial practices and future research directions are discussed.

The Impact

Today, product design process is facing a market globalisation led by distributed teams. The international market context, in which industrial companies evolve, leads design teams to work in a large multidisciplinary collaborative context using collaborative practices. In this context, product design process is driven by the integration and optimisation of stakeholders’ collaboration. Thus, to facilitate collaborative steps, new management strategies are defined and new information systems can be used. To this end, we have focused our article on the topic of collaborative product design project management. We have underlined the necessity to use quantitative and non-intrusive indicators during the management of collaborative design phases besides subjective evaluations. Tracking these indicators is performed in parallel to the existing approaches in order to evaluate the performance of collaborative design project. Moreover, these indicators can show the impact of the collaboration steps on the design project evolution. The computation of proposed indicators is based on precise metrics which details the completeness of the computer-aided design model and its evolution depending on the used collaborative tools and the project milestones. This computation uses the importance of each computer-aided design model part and the transformation rate of each part of the computer-aided design model.
