An analysis of information overload with implications for survey design research

Abstract

A laboratory‐type experiment was conducted to examine potential information overload causes and solutions. It was found that both information quantity and information complexity are potential causes of information overload. The experiment results also suggested that information overload problems may be reduced through carefully designed information display patterns. When designing survey questionnaires, attention must be given to potential causes of information overload. Methods of presenting information that ameliorate information overload must also be considered. As demonstrated in this study, survey designs can be tested in controlled, laboratory‐type experiments. The results of these experiments can then be used to improve the design of field survey questionnaires.     

The complexity of consumer experience formulation in the sharing economy

The study examines the complexity of the factors that influence overall perception among tourists who use peer-to-peer accommodation during their vacations. More specifically, it employs fuzzy-set Qualitative Comparative Analysis to analyse data from a sample of 712 peer-to-peer holidaymakers visiting Athens, Greece, and examines the socio-demographics of age and income along with the simple attributes of perceived risks, marketing and advertising, social aspects, and price and quality issues. The findings reveal three sufficient configurations that are able to influence the overall experience: (i) the price-quality nexus, (ii) risk perspective, and (iii) social interaction. The research also compares nonlinear analysis with the dominant parametric methods in tourism and hospitality research (regression; Cramer’s V), highlighting the suitability of the former for complexity examination. It further progresses from fit to predictive validity for the examined models, and contributes to both theoretical and methodological domains.     

Tourism as complex interdisciplinary research object

Tourism is currently a complex and globalised phenomenon with demonstrated socio-economic importance. While tourism is a socially recognised phenomenon, its status as scientific object within an academic field seems to be still in question. We ask the following questions: What is the order of construction of the field of knowledge constituted around tourism? Is it a paradigmatic order or an epistemic order? In what ways do the scientific object’s specificities constitute an important element of understanding of a new episteme? How do different definitions of tourism allow for a reconstruction of the field? This article seeks to summarise the current debate in the light of broader reconstructions of scientific discourse and reflect from an interdisciplinary epistemological perspective.     

Linking transformational leadership and employee creativity in the hospitality industry: The influences of creative role identity,creative self-efficacy,and job complexity

Integrating transformational leadership, creativity and social cognitive theories, we explore the relationships among transformational leadership, creative role identity, creative self-efficacy, job complexity and creativity. Structural equation modeling (SEM) with bootstrapping estimation was conducted using data from 395 supervisor–employee dyads from international tourist hotels in Taiwan. The results show that supervisors' transformational leadership positively influenced employee creative self-efficacy and creativity. Moreover, creative role identity was found to mediate the relationship between transformational leadership and employee creative self-efficacy, while both creative role identity and creative self-efficacy were found to mediate the relationship between transformational leadership and employee creativity. Specifically, job complexity was found to moderate the relationship between transformational leadership and employee creative role identity, the relationship between employee creative role identity and creative self-efficacy, and the relationship between employee creative self-efficacy and creativity. We discuss the implications of these results for research and practice in hospitality context.     

Changes in firm knowledge couplings and firm innovation performance: The moderating role of technological complexity

We investigate the effect of changes in a firm's knowledge couplings on its innovation performance. We develop arguments to explain how changes in couplings among existing knowledge domains and those between new and existing knowledge domains affect the generation of valuable inventions. We also examine how observed domain complexity, an indicator of the inherent interdependencies among knowledge domains, moderates the effects of changes in a firm's knowledge couplings on innovation performance. Our results suggest that a change in couplings among existing knowledge domains hurts innovation outcomes, but not when the degree of domain complexity is high, whereas coupling new and existing knowledge domains leads to improved outcomes, but not when the degree of domain complexity is high.

Product variety,sourcing complexity,and the bottleneck of coordination

Research summary: This paper studies the coordination burden for firms that pursue variety as their main product strategy. We propose that product variety magnifies the tension between scale economies in production and scope economies in distribution, giving rise to complex sourcing relationships. Sourcing complexity worsens performance and poses a dilemma for organization design: A hierarchical structure with intermediate coordinating units such as sourcing hubs reduces sourcing complexity for downstream distribution but creates bottlenecks at the hubs, hurting performance for both the hubs and downstream distribution. We empirically examine operations data for about 300 distribution centers within a major soft drink bottling company in 2010–2011. Results support our hypotheses, illuminating the source of complexity in multi‐product firms and the challenge for organization design in managing complexity. Managerial summary: This paper uses data for about 300 distribution centers within a major soft drink bottling company to study how a large product variety creates complex sourcing networks. We find that, in addition to poor performance (e.g., increased stockouts), complex sourcing networks can cause challenges for organization design. In particular, the benefits of converting an existing distribution center into a sourcing hub (i.e., reduction in sourcing complexity for downstream distribution) and the costs of doing so (i.e., reduction in performance for both the hubs and downstream distribution) are both real and significant. The design of an efficient sourcing network despite its complexity involves important managerial decisions. Experiences in building and managing such networks can be the basis of a dynamic capability. © 2016 The Authors. Strategic Management Journal published by John Wiley & Sons Ltd.     

Optimal portfolio allocation under the probabilistic VaR constraint and incentives for financial innovation

We characterize the investor’s optimal portfolio allocation subject to a budget constraint and a probabilistic VaR constraint in complete markets environments with a finite number of states. The set of feasible portfolios might no longer be connected or convex, while the number of local optima increases exponentially with the number of states, implying computational complexity. The optimal constrained portfolio allocation may therefore not be monotonic in the state–price density. We propose a type of financial innovation, which splits states of nature, that is shown to weakly enhance welfare, restore monotonicity of the optimal portfolio allocation in the state-price density, and reduce computational complexity. We are grateful to Ken Kavajecz and seminar participants at Harvard Business School, London School of Economics, Maastrict University, ZEI Bonn, and Danske Bank Symposium on Asset allocation and Value-at-Risk: Where Theory Meets Practice for comments on an earlier version of this paper.

Multidimensional principal–agent value for money in healthcare project financing

Value for money (VfM) is a key parameter for the public sector in the choice between a public–private partnership (PPP) and traditional procurement, especially for healthcare infrastructure. This paper investigates the differences in what VfM means to the public and private sectors.     

Unpacking the black box of successful ICT-enabled service transformation: how to join up the vertical,the horizontal and the technical

This paper aims to understand what goes on in the black box of successful, joined-up ICT-enabled service transformation, where complex interactions and integration must occur among the horizontal processes internal to a joined-up service delivery network, the vertical top-down processes of the organizations involved, and the change processes caused by using ICTs. A new conceptual framework is developed and applied to an illustrative case study of successful, joined-up service transformation in New Zealand.     

Changing management roles in the Scottish NHS: implications for management learning and development

The UK government's austerity means that public service providers, such as the National Health Service (NHS), are looking for efficiencies from service integration and collaborative working. This paper highlights how NHS (Scotland) management is coping with these changes and how the role of the manager and the nature of management development is being transformed. New forms and processes of management learning and development are needed for collaborative partnership working in multi-agency public service environments.
