Flow in multitasking : the effects of motivation, artifact, and task factors

textThe aims of this dissertation study are 1) to examine how the interplay of motivation, artifacts, and task interconnectedness affect users' flow experience, 2) to understand users' multitasking patterns by analyzing approaches and strategies in multitasking environments through a participatory design session, and 3) to come up with design insights and implications for desired multitasking environments based on findings from the quantitative and qualitative data analysis and synthesis. This dissertation employed the PAT (Person-Artifact-Task) model to examine factors that affect users' flow experience in computer-mediated multitasking environments. Particularly, this study focused on users' flow experience - sense of control, focused attention, curiosity, intrinsic interest and interactivity - in the context of multitasking. The dissertation begins with perspectives on human multitasking research from various disciplines. Emphasis is placed on how researchers have defined the term multitasking and the scope of previous multitasking research. In addition, this study provides definitions of the term task switching, which also has been used to describe human multitasking. The second section of this dissertation focuses on the literature, which characterizes factors and theoretical frameworks of human multitasking research. In this section, human multitasking factors were classified into internal and external factors to analyze factors from the micro to the macro perspective. More detailed definitions and comparisons are also addressed. To summarize and conclude the literature review, this study provides a synthesis framework of internal and external factors of human multitasking contexts. In section III, this dissertation introduces theoretical frameworks that include the constructs of the PAT (Person-Artifact-Task) model and flow model. The next three sections present the research design and two research methods - the experiment and participatory design. The results and discussion section includes the implications of interpreting people's flow experience with motivation, artifact (technology affordance type), and task interconnectedness through the PAT model. The study findings and implications should extend our understanding of multitasking behaviors and contexts and how the interplay of person, artifact, and task factors affects humans' flow experience. A concluding chapter explores future work and design implications on how researchers and designers can take contextual factors into consideration to identify the most effective multitasking in computer-mediated environments.Informatio

A Survey of Techniques For Improving Energy Efficiency in Embedded Computing Systems

Recent technological advances have greatly improved the performance and features of embedded systems. With the number of just mobile devices now reaching nearly equal to the population of earth, embedded systems have truly become ubiquitous. These trends, however, have also made the task of managing their power consumption extremely challenging. In recent years, several techniques have been proposed to address this issue. In this paper, we survey the techniques for managing power consumption of embedded systems. We discuss the need of power management and provide a classification of the techniques on several important parameters to highlight their similarities and differences. This paper is intended to help the researchers and application-developers in gaining insights into the working of power management techniques and designing even more efficient high-performance embedded systems of tomorrow

Effects of temporal correlations in social multiplex networks

Multi-layered networks represent a major advance in the description of natural complex systems, and their study has shed light on new physical phenomena. Despite its importance, however, the role of the temporal dimension in their structure and function has not been investigated in much detail so far. Here we study the temporal correlations between layers exhibited by real social multiplex networks. At a basic level, the presence of such correlations implies a certain degree of predictability in the contact pattern, as we quantify by an extension of the entropy and mutual information analyses proposed for the single-layer case. At a different level, we demonstrate that temporal correlations are a signature of a ‘multitasking’ behavior of network agents, characterized by a higher level of switching between different social activities than expected in a uncorrelated pattern. Moreover, temporal correlations significantly affect the dynamics of coupled epidemic processes unfolding on the network. Our work opens the way for the systematic study of temporal multiplex networks and we anticipate it will be of interest to researchers in a broad array of fields

The interplay between organizational polychronicity, multitasking behaviors and organizational identification: A mixed-methods study in knowledge intensive organizations

This paper investigates how individual perceptions and attitudes about an organization influence multitasking behaviors in the workplace. While we know that individuals are significantly influenced in their behaviors by the characteristics of their organizations (e.g. ICTs, organizational structure, physical layout), we still do not know much about how the way individuals interpret their organization influences their multitasking behaviors. Thus, we specifically hypothesize that the individual perception of the organizational preferences for multitasking (i.e. organizational polychronicity) engenders the actual multitasking behaviors that an individual enacts in the workplace. We also hypothesize that the attachment to the organization (i.e. organizational identification) moderates the above relationship. We conducted a mixed method study in two knowledge intensive organizations (an R&D unit and a university department) and collected data through a survey, diaries, and semi-structured interviews. Our findings support the first hypothesis but not the moderating role of organizational identification. However, this latter is directly related to how much a person is willing to work on multiple activities on a single day. Further, our study suggests that not only the organizational context should be investigated in the study of multitasking behaviors, but also the larger work context, including the individuals’ professional communities. We conclude with a discussion of theoretical and practical implications as well as methodological reflections on mixing methods in the study of multitasking in organizations

Integration of financial supervision

The emergence of financial conglomerates and multinational financial institutions as well as the development of new financial products have raised concerns as to the ability of separate sectoral supervisors and different national authorities to effectively oversee financial markets. Concentrating on the European situation, this paper addresses these concerns by putting special emphasis on the role of organizational form in the supervisory process of financial institutions. I will first outline the developments that have led to increasing pressures to reform the current supervisory systems in Europe, proceed to discuss both some common and specific aspects of supervision of financial conglomerates and multinationals, and, finally, examine the challenges related to the integration of supervision. Using theoretical framework derived from economic theory, this paper points that multitude of factors (eg, several multitasking-related concerns) are likely to affect the effectiveness of integrated supervision.financial supervision; financial conglomerates; multinationals; integration of supervision

Performance Pay, Delegation, and Multitasking under Uncertainty and Innovativeness An Empirical Investigation

The existing empirical evidence is somewhat inconclusive with respect to a number of the key predictions of the agency model. Although the reach of agency theory is considerably wider, the dominant portion of work has been taken up with examining the nature of the trade-off between risk and incentives, and the implications thereof for contractual design. More specifically, some researchers have recently noted that the predicted trade-off between risk and incentives turns out to be rather weak, and perhaps non-existent, when confronted with the available empirical evidence. In this paper, we examine the risk-incentives trade-off and related predictions from agency theory on the basis of data from a data set encompassing close to 1000 Danish firms. We find that the relation between the use of performance pay in these firms and the environmental uncertainty they confront which is one way to test the risk/incentives tradeoff is indeed weak and in many cases even perverse. We then suggest, in line with other recent contributions to the literature, that this may be caused by the widespread use of delegation. One effect of delegation is that it breaks the simple relation between risks and incentives. We examine the suggestion that that those firms that are more prone to use delegation of decision rights in their internal organization are facing an uncertain environment to a larger extent than the rest of the population. We argue that this constitutes an indirect confirmation of the hypothesis. We also examine the multi-tasking agency hypothesis that as risk increases, the flexibility of agents is restricted. We fail to find support for this hypothesis. It is suggested that the reason for this finding is also related to delegation.Uncertainty, pay-for-performance, delegation, innovation, competition

ORGANIZATIONAL CONTEXT AND MULTITASKING BEHAVIORS: A MIXED-METHOD STUDY

This paper investigates how individual perceptions and attitudes about an organization influence multitasking behaviors in the workplace. While we know that individuals’ behaviors are influenced by the characteristics of their organizations (e.g., ICTs, physical layout), we still do not know much about how the way individuals interpret their organization influences their multitasking behaviors. We first hypothesize that individual perceptions of organizational preferences for multitasking (i.e. organizational polychronicity) have impacts on actually enacted multitasking behaviors. We also hypothesize that the attachment to the organization (i.e. organizational identification) moderates the above relationship. We conducted a mixed method study in two knowledge intensive organizations and collected data through a survey, diaries, and semi-structured interviews. Our findings support the first hypothesis but not the moderating role of organizational identification. However, this latter seems to be directly related on how much a person is willing to work on different activities, but not on how much she interrupts others or accepts being interrupted. Further, our study suggests that not only the organizational context should be investigated in the study of multitasking behaviors, but also the larger work context, including the individuals’ professional communities

Export-Oriented Policies, Women’s Work Burden and Human Development in Mauritius

This paper, looking at the case study of Mauritius, attempts to understand the factors affecting the relationship between EOP, women’s work burden along different social backgrounds. The analysis is based on between-method triangulation consisting of a quantitative survey in the industrial sector and a qualitative survey in the industrial and services sectors. The main result shows that women and the social reproductive process were not affected in the same way depending on the socioprofessional background of the woman

Students\u27 use of personal technology in the classroom: analyzing the perceptions of the digital generation

Faculty frequently express concerns about students’ personal use of information and communication technologies in today’s university classrooms. As a requirement of a graduate research methodology course in a university in Ontario, Canada, the authors conducted qualitative research to gain an in-depth understanding of students’ perceptions of this issue. Their findings reveal students’ complex considerations about the acceptability of technology use. Their analysis of the broader contexts of students’ use reveals that despite a technological revolution, university teaching practices have remained largely the same, resulting in ‘cultural lag’ within the classroom. While faculty are technically ‘in charge’, students wield power through course evaluations, surveillance technologies and Internet postings. Neoliberalism and the corporatisation of the university have engendered an ‘entrepreneurial student’ customer who sees education as a means to a career. Understanding students’ perceptions and their technological, social and political contexts offers insights into the tensions within today’s classrooms

OPTIMAL JOB DESIGN IN THE PRESENCE OF IMPLICIT CONTRACTS

We characterize the optimal job design in a multitasking environment when the firms rely on implicit incentive contracts (i.e., bonus payments). Two natural forms of job design are compared: (i) individual accountability, where each agent is assigned to a particular job and assumes full responsibility for its outcome; and (ii) team accountability, where a group of agents share responsibility for a job and are jointly accountable for its outcome. The key trade-off is that team accountability mitigates the multitasking problem but may weaken the implicit contracts. The optimal job design follows a cut-off rule: firms with high reputation concerns opt for team accountability, whereas firms with low reputation concerns opt for individual accountability. Team accountability is more likely the more acute the multitasking problem is. However, the cut-off rule need not hold if the firm combines implicit incentives with explicit pay-per-performance contracts. JEL codes:
