The Effect of Leader Positive Affectivity on Team Member Turnover Intention and Team Organizational Citizenship Behavior

This paper develops two models to investigate the effect of team leader positive affectivity (PA) on team member turnover intention and team organizational citizenship behavior (OCB), at the individual and team levels, respectively. A two-wave longitudinal study was conducted involving a survey of 58 team leaders and 174 team members in a large Chinese telecom company across a three-month period. We found that team members’ organization-based self-esteem (OBSE) at Time 1 mediates the relationship between team leader PA at Time 1 and team member turnover intention at Time 2, whereas team aggregated OBSE at Time 1 mediates the relationship between leader PA at Time 1 and team OCB at Time 2.     

What: An argumentative groupware approach for organizing and documenting research activities

The topic of this paper is a process‐vs.‐product design method representation called Argumentative Writing (AW). Argumentative writing is a multi‐representation approach for conducting and reporting research projects. AW has at least two representations: one for structuring the problem‐understanding/solving process and one for communicating its product to others. We discuss WHAT, a hypertext‐based tool for AW. In WHAT (Writing with a Hypermedia‐based Argumentative Tool), the design process is captured using Rittel's Issue Based Information Systems (IBIS) method (Conklin, 1988; Hashim, 1990a; Rittel, 1980). The product of the design process is represented in WHAT using a general document‐representation scheme. In the Introduction we raise four major issues that we explore in the rest of the paper. Also in the Introduction, we show the impact the WHAT approach can have on organizational computing applications such as business education and training (Hashim, Rathnam, & Whinston, 1991) and the design of dialectical organizational information systems. The section “A Methodological Basis for AW Tools”; deals with the rationale behind choosing the IBIS method in capturing the design process. The section after that explains WHAT, and the section following it explores its use as a groupware tool. The applicability of WHAT and its pros and cons are discussed in two separate sections. In the Conclusion we outline the potentiality of the approach and present suggestions for its further development. Since our first reporting on WHAT (Hashim, 1990b), the AW approach was found applicable to educational, scientific, and business areas. One such application is for structuring case discussions in business schools (Hashim et al., 1991).

Extreme internal–external industrial-service flexibilities and interfirm cooperative networks in high-technology machine manufacturing

Most interfirm studies focus only on the strategies of strategic partnerships, such as joint ventures, technology transferring agreements, licensing agreements; the study here provides interfirm-network knowledge protocols for designing interfirm-service processes in the high-technology machinery industry (HTMI) by small-and-medium enterprise (SME) networks from the perspectives of extremely-rapid industrial-service flexibility (X-ISF). Based on the decision system analysis (DSA) method, this study constructs an X-ISF research model consisting of major variables of extremely-rapid internal ISF (X-I ISF), extremely-rapid external ISF (X-E ISF), and cooperative networks. This study applies a mixed methods (qualitative and quantitative) research design to understand interfirm-network decision-making and the influence of the antecedent conditions of internal and external X-ISF and cooperative upstream-to-downstream networks on firms' X-ISF performance. The study finds that the mutual relationships between X-I ISF and X-E ISF are substantially unbalanced — the impact on firm X-ISF performance by the external-to-internal (X-in) ISF is substantially greater than the impact from the internal-to-external (X-out) ISF. Recognize the need to lead with external-to-internal X-ISF to sustain the adoption-implementation of superior high-technology is the principal take-away strategy implication.

A Measure for Companies' Customer Portfolio Management

Purpose/Contribution: Customer portfolio management (CPM) is one of the key areas of customer-relationship and network management in business markets. However, there is scant research about the implementation of this concept in business. This article contributes to this conceptually rich but empirically nascent field of CPM research by (1) conceptualizing customer portfolio management, (2) forming a measure for it, (3) validating the suggested measure, and (4) suggesting implications for future research and management.

Methodology: A CPM construct is proposed based on the synthesizing of the theory and the findings from a qualitative field study of companies' management practices. The suggested construct is formative and consists of the following four dimensions: analysis efforts, analysis design, responsiveness efforts, and responsiveness design. Hence, this conceptualization takes into account both the strength and style of companies' CPM practices. The measure is validated following Diamantopoulos and Winklhofer's (2001) Diamantopoulos, A. and Winklhofer, H. 2001. Index construction with formative indicators: An alternative to scale development. Journal of Marketing Research, 38(2): 269–277. [Crossref], [Web of Science ®] , [Google Scholar] guidelines for developing formative measures. Together with the content validity established in the conceptual phase of the research, the results from a cross-industry survey of 212 companies give support to the construct validity of the suggested CPM measure. Partial least squares modeling is applied in validating the measure.

Implications: This study gives an extensive, up-to-date review of customer portfolio management and provides measures for future research on companies' CPM practices and performance. Further, the theory and the field study highlighted several central topics that should be addressed in future CPM studies. The resulting managerial implications derive from the discussion on the key aspects of developing CPM practices in business.     

Maximizing User Interactivity through Banner Ad Design

This research developed criteria for an online banner ad design to maximize user interactivity. The ad's design criteria were based on studies on interactivity, animation, persuasiveness of emotional and rational appeals in ads, animation, ad placement, size, and metrics. The ad was deployed and measured for effectiveness by using behavioral response metrics: click-through rates and mouse rollovers. Findings show that the ad designed according to the criteria garnered more user interaction than the other ads deployed during the same time. This has value for advertisers that need to evaluate online banner advertising design and need to make informed decisions on advertising strategy and campaigns.

How companies use typeface design to engage consumers in charitable activities

This research examines how the typeface design in a charitable appeal affects consumers' evaluations of the ad and, in turn, their willingness to engage in the advertised charitable activities. We propose that the typeface's simulation of a handwritten note creates a sense of connectedness to the information sender (e.g., organization, brand), which subsequently increases consumers' willingness to engage in the advertised charitable activities. Six experiments, including laboratory and field studies, provide support for the typeface effect and further support the underlying process by (1) directly examining connectedness, and (2) manipulating brand attachment, showing that a handwritten typeface creates a more positive effect when the viewer is not strongly connected to the brand (vs. having a strong brand attachment). Our findings provide useful guidelines for brand managers, social marketers and charity fundraisers regarding how and when to use a handwritten typeface design.     

Exploring the factors affecting customers’ intention to purchase a smart speaker

Although the sale of smart speakers is predicted to have a significant growth, the usage of smart speakers is not very popular in some countries and need further investigation. While the Bluetooth earphone and speakers are popular, the sales of smart speakers are challenging. Hence, the research purpose is to explore the determinants of the intention to purchase smart speakers and compare the differences between customers and potential customers. This study proposes ten hypotheses in a research framework according to the diffusion of innovation theory (DOI), task-technology fit (TTF), and perceived values. This study develops an online questionnaire to collect data from popular social networking sites. Finally, 249 valid responses collected from the website users are remained. The ten hypotheses are validated by using smartPLS software. According to the path analyses, five hypotheses were supported in potential customer group while only three hypotheses were supported in customer group. Users' perceived emotion-related value had significant direct influences on all customers' intention to buy smart speakers. Surprisingly, TTF was demonstrated to not significantly influence customers’ intention to purchase. The insights of the findings can be provided to smart speaker developers to design their products and sales strategies.
