Show moreThis article demonstrates the use of a diary technique in a construction setting. The advantage of a diary study over other methods for capturing subjective experience is its ability to capture the thoughts, decisions, actions, and emotions of individuals in situ – while they are working in their natural setting – at multiple points in time during an individual’s workweek. Hence, the diary method is uniquely designed to answer questions about group-level trends as well as individual behavior. The specific goal of the study reported in this article was to derive an understanding of the types of fast decisions and actions that are made following a workflow disruption and how the disruption impacts the worker’s state of mind. The analyses revealed that there was a group-level positive correlation between experiencing a disruption and initiating a fast improvised decision and action. However, some workers tended to improvise frequently when disrupted while others did not. The analyses also revealed that the workers’ emotions fluctuated throughout the week, and two emotions – determined and interested – tended to decline following a disruption. But, some of the workers also experienced increases in their negative emotions while others did not, suggesting that not all workers react in the same way to disruptions. Consequently, the diary technique provides a novel way to identify the impact of disruptive events on worker decision-making and performance.

Title: Using ecological momentary assessment to understand a construction worker’s daily disruptions and decisions (Working Paper)

Show moreCapturing the momentary decisions and actions made by construction workers in response to workflow disruptions is challenging because, until now, there has not been a minimally-disruptive data collection method that allows workers to identify their decision process “in the moment.” However, an Ecological Momentary Assessment (EMA) method – designed to capture momentary work experiences in natural settings – can provide researchers with detailed information about the daily challenges experienced by workers during the course of performing their tasks. An explanation of the method is provided, along with examples of the types of research questions that can be addressed and appropriate analysis techniques. The EMA method is being used on a federally-funded research program in the United States that is investigating how construction workers adapt to workflow disruptions by improvising their decisions and actions. Consequently, this article demonstrates the use of the method by presenting an idiographic study of William, an electrical construction worker. The evaluation of William’s disruptions, decisions, and actions elucidated an important relationship: every one of William’s disruptions required an improvisational action in order to continue working. The EMA method opens the door to the development of new theories about rapid decisions and subsequent actions on construction sites.

Show moreThis paper uses data from 1,042 tweets posted by or mentioning Chicago Aldermen or Mayor Rahm Emanuel to examine how Chicago politicians use social media. Twitter provides a public communication medium in which constituents and their representatives can have two-way conversations that others can witness and record, and we used qualitative and social network methods to examine conversations between Chicagoans and representatives in city government. We coded the contents of each tweet over the two-week time period (e.g., official business, fundraising) and created representations of the social networks created by the users’ following behaviors. These networks indicate who receives politicians’ tweets and help identify the audiences for political messaging in social media. Our analysis indicates that Chicago’s Aldermen and Mayor use Twitter for social conversations more often than political ones, and that only a small number of Aldermen dominate the resulting conversation networks.

Title: Selecting a Compensation Strategy to Control Project Duration: Empirical Comparison of Lump Sum and Reimbursable Strategies (Working Paper)

Show moreReducing project duration is a significant concern for many industries in the speed-to-market era. Numerous studies have examined the effects of project delivery methods on speeding up the process of construction. However, no study has quantitatively compared the effect of using different compensation strategies on schedule duration and schedule reduction. Using the data obtained from 175 international construction projects, this paper focuses on examining the influence of compensation strategy (lump sum versus reimbursable) on project duration while specifically taking into account the industry sector (heavy industrial versus light industrial). The results of the study provide empirical evidence that using a reimbursable compensation strategy can potentially shorten the procurement duration, construction duration, and overall project duration of heavy industrial projects. However, reimbursable contracting did not appear to reduce the project duration on light industrial projects.

Show morePublic officials’ communication has been explored at length in terms of how such their statements are conveyed in the traditional media, but minimal research has been done to examine their communication via social media. This paper explores the kinds of statements U.S. officials are making on Twitter in terms of the actions they are trying to achieve. We then analyze the correlation between these statements, Congressional communication network structures, and voting behavior. Our analysis leverages over 29,000 tweets by members of Congress in conjunction with existing DW-NOMINATE voting behavior data. We find that pro-social and self-promoting statements correlate with Congressional voting records but that position within the Congressional communication network does not correlate with voting behavior.

Title: Completing the Puzzle: Comparable Community Determination for Illinois Municipalities

Show moreIn the process of negotiating for new contracts, public safety (i.e. Police and Firefighters) employee unions and municipal managers compare the essential elements of their contract (i.e. wages) with those of other “comparable” municipalities. The wages, benefits and working conditions of other “comparable” municipalities are used to provide evidence supporting the positions taken on both sides of the negotiating table. The problem is that negotiating teams rarely employ a consistent and accurate method to determine which municipalities should be compared to their own. Negotiating teams make their own determinations of comparability, which must be defended should arbitration proceedings become necessary. However, most of the methods of comparability determination currently employed by negotiating teams are extremely simple and are lacking a sound analytical basis. These methods are inadequate in terms of accuracy, and would be difficult to defend in arbitration proceedings. The method outlined in the following report provides a sound analytical basis for comparability determination. The recommendation is to employ the use of Comparability Tables. Comparability Tables : The Tables provide a list of which communities are most comparable to each particular community, and how comparable they are. This solution is augmented by three supporting elements which help to address the weaknesses apparent in the Comparability Tables. The three supporting elements are a Dissimilarity Matrix, Factor Analytic Rankings, and Factor Analytic Tables. Dissimilarity Matrix : The Matrix provides a comparability determination for communities not listed on a particular community’s Comparability Table. Factor Analytic Rankings : The Rankings allow a determination of why two communities are or are not comparable. Factor Analytic Tables : The Tables allow a quick reference to the particular characteristics of each community. The Comparability Tables, along with the supporting elements, provide negotiating teams with a list of comparable communities that is more accurate and defensible than the lists provided by other methods. This method describes which communities are comparable, how comparable they are, and why they are comparable. Negotiating teams who employ this method of comparability determination can approach their negotiations confident that their choice of comparable communities is accurate and can stand up to an arbitrator’s inquiry.
