Due to increasing urbanization, nowadays, cities are facing challenges spanning multiple domains such as mobility, energy, environment, etc. For example, to reduce traffic congestion, energy consumption, and excessive pollution, big data gathered from legacy systems (e.g., sensors not conformant with modern standards), geographic information systems, gateways of public administrations, and Internet of Things technologies can be exploited to provide insights to assess the current status of a city. Moreover, the possibility to perform what-if analyses is fundamental to analyzing the impact of possible changes in the urban environment. The few available solutions for scenario definitions and analyses are limited to addressing a single domain and providing proprietary formats and tools, with scarce flexibility. Therefore, in this paper, we present a novel scenario model and editor integrated into the open-source Snap4City.org platform to enable several processing and what-if analyses in multiple domains. Different from state-of-the-art software, the proposed solution responds to a series of identified requirements, implements NGSIv2-compliant data models with formal descriptions of the urban context, and a scenario versioning method. Moreover, it allows us to carry out analyses on different domains, as shown with some examples. As a case study, a traffic congestion analysis is provided, confirming the validity and usefulness of the proposed solution. This work was developed in the context of CN MOST, the National Center on Sustainable Mobility in Italy, and for the Tourismo EC project. [ABSTRACT FROM AUTHOR]

Despite the growing empirical evidence on the beneficial effects of "micro" work breaks, scant research has examined "online" work breaks. Thus, the purpose of this study is to explore the nature and effects of online work breaks. Through an in-depth qualitative study of a diverse set of 33 full-time working professionals, we identified conditions under which online breaks occur as well as the characteristics and outcomes of these breaks. Interestingly, our findings point to both negative and positive outcomes associated with online breaks, largely dependent on an individual's ability to self-regulate. Our grounded theory approach allows us to develop a richer description of online work breaks and a theoretical model to help guide future research. [ABSTRACT FROM AUTHOR]

Cincinnati, like other new migration areas, has recently experienced tremendous growth in the Latino immigrant population. Because greater health disparities exist for Latinos compared to both majority and other minority groups, it is essential to understand how migratory patterns and healthcare infrastructure are related. In this study, social network analysis (SNA), which quantitatively assesses and evaluates network formation and network relationships, was used to investigate the structure of the Greater Cincinnati Latino health network. Referral and collaboration networks were assessed for 29 individuals serving the Latino community. Results indicated the desired collaboration network was nearly twice as dense as either the physical or the mental health referral networks. The physical network was also denser than the mental health network. Similar results were found when analyzing network centralization. Taken together, results indicate a need for additional strategic partnerships between Latino-serving providers and the Latino-serving community. Specific recommendations are briefly discussed.

- Abstract
Purpose: The purpose of this paper is to explore employee perceptions of communication in psychologically safe and unsafe clinical care environments.Design/methodology/approach: Clinical providers at the USA Veterans Health Administration were interviewed as part of planning organizational interventions. They discussed strengths, weaknesses, and desired changes in their workplaces. A subset of respondents also discussed workplace psychological safety (i.e. employee perceptions of being able to speak up or report errors without retaliation or ostracism--Edmondson, 1999). Two trained coders analysed the interview data using a grounded theory-based method. They excerpted passages that discussed job-related communication and summarized specific themes. Subsequent analyses compared frequencies of themes across workgroups defined as having psychologically safe vs unsafe climate based upon an independently administered employee survey.Findings: Perceptions of work-related communication differed across clinical provider groups with high vs low psychological safety. The differences in frequencies of communication-related themes across the compared groups matched the expected pattern of problem-laden communication characterizing psychologically unsafe workplaces.Originality/value: Previous research implied the existence of a connection between communication and psychological safety whereas this study offers substantive evidence of it. The paper summarized the differences in perceptions of communication in high vs low psychological safety environments drawing from qualitative data that reflected clinical providers' direct experience on the job. The paper also illustrated the conclusions with multiple specific examples. The findings are informative to health care providers seeking to improve communication within care delivery teams.

The Internet of things has produced several heterogeneous devices and data models for sensors/actuators, physical and virtual. Corresponding data must be aggregated and their models have to be put in relationships with the general knowledge to make them immediately usable by visual analytics tools, APIs, and other devices. In this paper, models and tools for data ingestion and regularization are presented to simplify and enable the automated visual representation of corresponding data. The addressed problems are related to the (i) regularization of the high heterogeneity of data that are available in the IoT devices (physical or virtual) and KPIs (key performance indicators), thus allowing such data in elements of hypercubes to be reported, and (ii) the possibility of providing final users with an index on views and data structures that can be directly exploited by graphical widgets of visual analytics tools, according to different operators. The solution analyzes the loaded data to extract and generate the IoT device model, as well as to create the instances of the device and generate eventual time series. The whole process allows data for visual analytics and dashboarding to be prepared in a few clicks. The proposed IoT device model is compliant with FIWARE NGSI and is supported by a formal definition of data characterization in terms of value type, value unit, and data type. The resulting data model has been enforced into the Snap4City dashboard wizard and tool, which is a GDPR-compliant multitenant architecture. The solution has been developed and validated by considering six different pilots in Europe for collecting big data to monitor and reason people flows and tourism with the aim of improving quality of service; it has been developed in the context of the HERIT-DATA Interreg project and on top of Snap4City infrastructure and tools. The model turned out to be capable of meeting all the requirements of HERIT-DATA, while some of the visual representation tools still need to be updated and furtherly developed to add a few features.

- Abstract
Recently, employee engagement has emerged as a topic of great interest to both practitioners and academics, likely due to its association with numerous positive individual and organizational outcomes. While these associations are informative, leaders require specific practices, which they may enact in order to maximize the engagement levels of their employees. Utilizing a mixed methods approach, this study investigates specific practices that may foster employee engagement. First, 32 key informant interviews were conducted across the U.S. Department of Veterans Affairs, Veterans Health Administrations (VHA) to understand what practices lead to a more engaged workforce. Seven categories of practices emerged, including modeling engagement, information sharing, acquiring resources, promoting psychological safety, employee recognition, building a team orientation, and taking a personal interest in employees. Second, these seven practices were quantitatively tested and validated on a sample of 183 VHA medical facilities. Using multi-source, all seven practices correlated significantly with engagement and its three subfactors (i.e. cognitive, physical, and emotional engagement), with the exception of acquiring resources and employee recognition with emotional engagement. Findings are discussed, along with practical and scientific implications, limitations, and directions for future research. [ABSTRACT FROM AUTHOR]

Bologna, Daniele A., Thomas, Brandon, and Sehgal, Shagun
- Abstract
Employee engagement has recently garnered vast interest from both the academic and practitioner communities, likely due to its link with numerous positive individual and organizational outcomes. Here, we introduce a new concept, unexpected work, which occurs when more resources (e.g., time, energy) from an individual are required than the individual originally anticipated. Findings from two lab experiments suggest that unexpected work has a generally negative relationship with engagement, with a particularly strong impact on the engagement subfactor of absorption. Further, our findings suggest changes in engagement may have a delayed relationship with performance. Findings are discussed along with limitations and implications for future research.

Bologna, Daniele A. and Weiskircher, Kathryn
- Abstract
Student engagement has been linked to various positive individual level outcomes, such as classroom performance and well-being. However, with external factors (e.g., technology, part-time jobs, and social demands) competing for students' attentional resources, keeping students engaged in the classroom and in their programs of study becomes a daunting task for educators. This study aims to outline a step-by-step process for identifying factors driving student engagement in an academic program. We iteratively couple this outline with a case example, where we identify a set of antecedents related to student engagement and academic performance at a large Midwestern University. To identify potential antecedents of engagement in our case example, a mixed-methods, step-by-step process was utilized. This methodology revealed three higher-order factors impacting student engagement; namely, professor influence, learning environment, and student interaction. Results are presented and discussed, as well as limitations and implications. [ABSTRACT FROM AUTHOR]

- Abstract
Through our grounded theory qualitative research, we explore how employees use technology to take breaks in the workplace. To better understand the phenomenon, we first examine why employees take online breaks as opposed to traditional offline breaks. We then explore triggers and consequences of online breaks. We identify two types of online break activities: respite, associated with pleasure-seeking, and chore, associated with non-work-related duties and responsibilities. Our findings suggest that these two types are associated with different categories of triggers (individual factors such as need for recovery and work-life balance, and job-related factors such as affective events, task and skill variety, and workload), and consequences (momentary recovery, learning, and satisfaction). Our participants suggest that although respite activities are more likely to bring relief from work demands, to help them be more productive, these breaks should be taken in a self- disciplined manner. To synthesize our findings, we present a process model of online work breaks. [ABSTRACT FROM AUTHOR]
