Virtual Teams: The Impact of Varying Levels of Virtuality on Project Team Performance

Although virtual teams have existed for over two decades, in recent years the Covid-19 pandemic led to a wider adoption and transition to virtual teamwork by most organizations. Virtuality is operationalized as the proportion of work done remotely or virtually on a project. This research studies the moderating effects of virtuality in project teams on communication frequency, leadership effectiveness, and project team performance. Using the theoretical frameworks of Adaptive Structuration Theory and Transformational Leadership Theory, a survey was carried out that informed this cross-sectional study. Respondents were project team members and managers who were involved in AEC (Architecture, Engineering and Construction) and Finance/IT projects before and during the Covid-19 pandemic. This study showed that the inverted-u relationship between communication frequency and project performance was preserved in only low virtuality teams, while the shape of the curve was different for high virtuality teams. AEC project performance was also found to be more sensitive to communication frequency, as these projects exhibited inverted-u relationship with performance compared to Finance/IT projects which was more linear. Regardless of the levels of virtuality in project teams, transformational leadership leads to significantly better performance in both types of projects. This study contributes to the body of literature in project management and information systems by measuring one of several dimensions of virtuality in the proposed model and provides insights for project managers in industry to better lead their virtual project teams

Data on mixing and curing methods effects on the compressive strength of concrete

Curing, though important is sometimes underrated in concrete production. This dataset provided shows the effects of four (4) different methods of curing on two distinct mix ratios. The data provided in this article are for a study that was conducted on one hundred and sixty (160) cube samples of mix ratios 1:2:4 and 1:1.5:3 while employing four (4) different methods of curing. The data given in the article displays the finding of the study. The findings can aid in prediction and optimization of concrete behavior and compressive strength when any of the curing methods are utilized

Adaptation of the Wound Healing Questionnaire universal-reporter outcome measure for use in global surgery trials (TALON-1 study): mixed-methods study and Rasch analysis

BackgroundThe Bluebelle Wound Healing Questionnaire (WHQ) is a universal-reporter outcome measure developed in the UK for remote detection of surgical-site infection after abdominal surgery. This study aimed to explore cross-cultural equivalence, acceptability, and content validity of the WHQ for use across low- and middle-income countries, and to make recommendations for its adaptation.MethodsThis was a mixed-methods study within a trial (SWAT) embedded in an international randomized trial, conducted according to best practice guidelines, and co-produced with community and patient partners (TALON-1). Structured interviews and focus groups were used to gather data regarding cross-cultural, cross-contextual equivalence of the individual items and scale, and conduct a translatability assessment. Translation was completed into five languages in accordance with Mapi recommendations. Next, data from a prospective cohort (SWAT) were interpreted using Rasch analysis to explore scaling and measurement properties of the WHQ. Finally, qualitative and quantitative data were triangulated using a modified, exploratory, instrumental design model.ResultsIn the qualitative phase, 10 structured interviews and six focus groups took place with a total of 47 investigators across six countries. Themes related to comprehension, response mapping, retrieval, and judgement were identified with rich cross-cultural insights. In the quantitative phase, an exploratory Rasch model was fitted to data from 537 patients (369 excluding extremes). Owing to the number of extreme (floor) values, the overall level of power was low. The single WHQ scale satisfied tests of unidimensionality, indicating validity of the ordinal total WHQ score. There was significant overall model misfit of five items (5, 9, 14, 15, 16) and local dependency in 11 item pairs. The person separation index was estimated as 0.48 suggesting weak discrimination between classes, whereas Cronbach's α was high at 0.86. Triangulation of qualitative data with the Rasch analysis supported recommendations for cross-cultural adaptation of the WHQ items 1 (redness), 3 (clear fluid), 7 (deep wound opening), 10 (pain), 11 (fever), 15 (antibiotics), 16 (debridement), 18 (drainage), and 19 (reoperation). Changes to three item response categories (1, not at all; 2, a little; 3, a lot) were adopted for symptom items 1 to 10, and two categories (0, no; 1, yes) for item 11 (fever).ConclusionThis study made recommendations for cross-cultural adaptation of the WHQ for use in global surgical research and practice, using co-produced mixed-methods data from three continents. Translations are now available for implementation into remote wound assessment pathways
