By value creation, we mean the activities, processes, and strategies that the project team uses to increase benefits and/or reduce costs in the project. By synthesizing the literature on project management and system dynamics, we developed a simulation model with various structures underlying project dynamics. We considered four structures that influence project realized value: project team features, project characteristics, project controls and value creation processes, and project remedial actions due to ripple effects. The resulting model can systematically examine the interplay of value creation processes: work progression, rework, redesign and innovation, and rescheduling. We used the model to explain how the project team’s capability, motivation, and speed of making the best-for-project decisions ensure that the value creation goals are met. We simulate various scenarios that show the significance of the processes and their influencing structures on the realized value. The results present how endogenous and exogenous drivers of system behavior unfold over time and provide a richer understanding of the effect of various model structures such as project complexity and uncertainty on value creation.","PeriodicalId":14606,"journal":{"name":"issue 2","volume":"609 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77490488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For large, highly diverse teams, such as those found in architecture and engineering (A/E) who work under timebased deadlines, homophily—or the tendency to seek interactions with others of similar backgrounds and values—can play a role in how individuals communicate. Homophily is potentially damaging to teams that must coordinate information from a diverse membership, since communication may become less likely to occur across disciplines. Therefore, this research examines the extent to which a sampled A/E team exhibits homophily in their information exchanges across multiple communication media, when under the moderating effect of two different levels of time pressure. The study uses a social network analysis of the communication patterns in an 18-member studio team working for a national A/E firm located in the southeastern United States. The results show some evidence of homophily as a predictor of information exchanges when controlling for the hierarchical ties within the studio team and the physical distance between its members in the office. In a low time pressure work environment, face-to-face communication was more likely when members were of the same gender. This effect was not present when the team was under high time pressure, where face-to-face interactions were instead more likely between members of the same discipline. Homophily in phone communication was found in the generational similarity of team members, regardless of time pressure. There was little evidence that homophily was a predictor of email communication. These results have implications for the design of studio workplaces that support information-rich interactions, the assignment of individual designers to project teams that are more likely to interact with co-workers from different backgrounds, and organizational policy regarding the use of specific communication media based on the project schedule and time pressure.","PeriodicalId":14606,"journal":{"name":"issue 2","volume":"447 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90720817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The virus spread rapidly throughout the country and around the globe. In an effort to prevent the spread of the virus, all countries significantly limited social interaction, which also curbed all sports, social, and leisure activities. AIM: The main research objective of this paper was to determine whether there is a statically significant relationship between the potential interest in information retrieval and the subsequent possible change in behaviour and in preferences in relation to selected anabolic androgenic substances and steroids, before and after the global COVID-19 pandemic in the context of biological age, the highest level of education attained, and work status. METHODS: Secondary information sources were accessed via the citation database Web of Science and the Scopus citation and reference database. Selected mathematical-statistical methods were used to analyse the data and interpret the findings. SAMPLE: The method of snowball sampling was used, allowing us to gather a pool of 127 respondents. RESULTS: The results suggest that there could be a statically significant relationship between the change in behaviour and in preferences in relation to selected anabolic androgenic substances and steroids before and after the global COVID-19 pandemic with regard to biological age and work status. It was also determined that the highest level of education attained by the respondents has no effect on this issue. CONCLUSION: The most common reason for the change in behaviour and in preferences associated with selected anabolic androgens and steroids before and after the COVID-19 pandemic was rapid muscle mass growth and an increase in muscle strength. The least intrinsically motivating reason was shortening the regeneration period of the body after a training session. © 2021, Sdruzeni SCAN.
