Information technology changes rapidly, and the market trend flow changes even faster. The information systems (IS) department in a technological oriented environment has to ensure that the plans or solutions made by the IS department can align with organizational strategy to avoid resources waste, and adaptability is a crucial issue for an IS department too. This study believes that adaptability and alignment of the IS department are ambidexterity. The concept of knowledge use effectiveness (KUE), based on the human agency theory, proposed a research model mainly founded on intellectual capital, human agency theory, and contextual ambidexterity, and used intellectual capital (including human, structure and relational capital) as a framework to find the antecedents of knowledge usage.

This study conducts an empirical research method and collects 150 valid cases from the IS department employees in Taiwan.

The results of this study are: (1) KUE in an IS department significantly improves the ambidexterity; (2) intellectual capital has a positive influence on KUE; (3) despite human capital having no influence on iteration, iterational KUE has no influence on adaptability.

For academics, this study has developed KUE through a novel perspective and uses the concept of the human agency to articulate the characteristic of KUE, and thus has combined the intellectual capital, human agency and contextual ambidexterity into a research model. For managers, they should learn that KUE has a positive effect on the IS department ambidexterity, composed of alignment and adaptability. By knowing that, they can understand the concrete elaboration of KUE much better. Therefore, enhancing the process of knowledge usage can be a practical and useful way of improving an IS department performance.

The purpose of this paper is to gain a clear understanding of the impact of uncommon use of knowledge (adaptation and augmentation) on the performance of information systems (IS) departments, and to explore the effects of human-resources management (HRM) practices on uncommon use of knowledge.

A questionnaire-based survey was used to measure the constructs of the research model. A survey package was delivered to project managers or team leads and 133 responses were returned.

The empirical results indicate that knowledge adaptation has a significant effect on departmental performance, whereas knowledge augmentation is more important to innovation than to routine departmental performance. The results also show that, while knowledge adaptation can be enhanced by communication and an uncertainty-avoidance culture, knowledge augmentation is an outcome of shared decision-making, the use of teams, and innovation-based policies.

Given the positive impact of uncommon use of knowledge on IS department performance, future research should explore other factors besides HRM practices to boost it.

The results can serve as guidance for managers looking to select HRM practices to promote uncommon use of knowledge.

This study introduces knowledge adaptation and knowledge augmentation as the component processes of uncommon use of knowledge to the IS discipline, and empirically validates the antecedents and consequences of uncommon use of knowledge using survey data.

The purpose of this paper is to integrate psychological dimension, social dimension, and environmental dimension – six internet psychological characteristics (dissociative anonymity, invisibility, asynchronicity, solipsistic introjection, dissociative imagination, and minimization of status and authority), deindividuation, social influence (subjective norm and descriptive norm), and containment theory (inner containment and outer containment) – to propose an innovative model which can make up for deficiencies in previous studies of the toxic online disinhibition effect.

On the basis of 530 valid responses collected from an online survey questionnaire, partial least squares technology was used to examine the research model.

The result shows that dissociative anonymity has a significant impact on deindividuation and toxic disinhibition. In addition, asynchronicity and dissociative imagination have a direct effect on toxic disinhibition. Besides, in social influence, the authors found that subjective norm is a stronger predictor of toxic disinhibition than descriptive norm. Moreover, in containment theory, the result shows that inner containment can effectively reduce toxic disinhibition but not outer containment.

This study can provide academics and practical side empirical evidence as to what factor would cause toxic disinhibition and provides an innovative view regarding the relationship between social influence and containment theory on toxic disinhibition.

This study investigates factors that motivate social media users to retransmit rumors. We focus on everyday rumors rather than catastrophic rumors and develop a model of everyday rumor retransmission based on the uses and gratification theory, the rumor retransmission model, and the basic law of rumor.

An Internet survey is conducted to collect data and test the proposed model. This study’s hypotheses are tested through partial least squares regression analysis.

The results show that socializing, information seeking and status seeking increase the intention to retransmit rumors. Perceived rumor credibility has a moderating effect on the impacts of socializing and status seeking on retransmission intention.

Our research model provides a theoretical foundation for future studies that want to explore motivations or values that determine rumor-sharing intention on social media. The findings can help government agencies and businesses to manage rumor retransmission on social media.

The purpose of this paper is to examine the complex relationships between permeability, work-family conflict, moral disengagement, behavioral disengagement, job strain and job engagement. In addition, this study aims to determine whether moral disengagement acts as a moderator and mediator in the relationship between work-family conflict and behavioral disengagement.

The authors apply partial least squares structural equation modeling to test the hypotheses, using a sample of 176 valid responses.

The results indicate that permeability is likely to promote work-family conflict, which in turn may trigger moral disengagement. Moral disengagement may lead to behavioral disengagement, which in turn may increase job strain and decrease job engagement. The findings also show that work-family conflict does not have a significant effect on behavioral disengagement, suggesting that moral disengagement fully mediates the influence of work-family conflict on behavioral disengagement. In addition, the moderating effect of moral disengagement is not significant.

Applying the transactional model of stress and coping theory and the moral disengagement theory, this study contributes to a better understanding of employees' experience of job strain caused by work-family conflict (induced by permeability of IM usage), as well as the employee's coping response.

The purpose of the study is to focus on the enhancement of knowledge management (KM) performance and the relationship between organizational culture and KM process intention of individuals because of the diversity of organizational cultures (which include results-oriented, tightly controlled, job-oriented, closed system and professional-oriented cultures). Knowledge is a primary resource in organizations. If firms are able to effectively manage their knowledge resources, then a wide range of benefits can be reaped such as improved corporate efficiency, effectiveness, innovation and customer service.

The survey methodology, which has the ability to enhance generalization of results (Dooley, 2001), was used to collect the data utilized in the testing of the research hypotheses.

Results- and job-oriented cultures have positive effects on employee intention in the KM process (creation, storage, transfer and application), whereas a tightly controlled culture has negative effects.

However, it would have been better to use a longitudinal study to collect useful long-term data to understand how the KM process would be influenced when organizational culture dimensions are changed through/by management. This is the first limitation of this study. According to Mason and Pauleen (2003), KM culture is a powerful predictor of individual knowledge-sharing behavior, which is not included in this study. Thus, this is the second limitation of this paper. Moreover, national culture could be an important issue in the KM process (Jacks et al., 2012), which is the third limitation of this paper for not comprising it.

In researchers’ point of view, results- and job-oriented cultures have positive effects, whereas a tightly controlled culture has a negative effect on the KM process intention of the individual. These findings provide evidences that challenge the perspective of Kayworth and Leidner (2003) on this issue. As for practitioners, management has a direction to modify their organizational culture to improve the performance of KM process.

Both behavioral and value perspectives of the organizational cultural dimensions (results-oriented, tightly control, job-oriented, sociability, solidarity, need for achievement and democracy) should be examined to ascertain their effects firstly on KM culture and then on the KM process intention of the individual. It is hoped that the current study will spawn future investigations that lead to the development of an integrated model which includes organizational culture, KM culture and the KM process intention of the individual.

The results-oriented, loosely controlled and job-oriented cultures will improve the effectiveness of the KM process and will also increase employees’ satisfaction and willingness to stay with the organization.

Knowledge loss impact on the performance of management information system (MIS) departments due to its influence on absorptive capacity. Furthermore, knowledge retention in human resource management and information system application is also included in the research model, in order to examine their effectiveness in mitigating knowledge loss. The paper aims to discuss these issues.

Survey method and hypotheses are tested with the collected data from 191 Taiwanese IS personnel.

The results not only indicate knowledge loss has impacts on the absorptive capacity and performance of MIS departments while information systems could mitigate knowledge loss, but also provide deeper understanding of knowledge loss and potential issues for academics; as for practitioners, this study could serve as a reference to design and adopt knowledge management (KM) mechanisms.

KM is an important issue for organizations since it is the source of competitive advantages and excellent performance, although the investment in KM is not necessary effective in retaining knowledge. This study conducts survey to examine the influences of knowledge loss in MIS departments, since the high turnover rate of employees and the rapid environmental changes in technical world may worsen the situation. According to dynamic capability theory, absorptive capacity is a critical ability to have while facing turbulent environment.

Though prior research has recognized business skills as one of the keys to successful information system development, few studies have investigated the determinants of an IS developer’s behavioral intention to learn such skills. Based on the motivation-ability-role perception-situational factors (i.e. the MARS model), the purpose of this paper is to argue that the intention of IS developers to acquire business skills is influenced by learning motivation (M), learning self-efficacy (A), change agent role perception (R), and situational support (S).

Data collected from 254 IS developers are analyzed using the partial least squares technique.

Results show that a developer’s intention to learn business skills is positively influenced by intrinsic learning motivation and both absolute and relative learning self-efficacy. Furthermore, in comparison to two other change agent roles, the advocate role leads to a significantly higher level of learning intention. Finally, work and non-work support positively influence both extrinsic and intrinsic learning motivation. Notably, non-work support has a greater impact on both absolute and relative learning self-efficacy.

Though many of the proposed hypotheses were supported, results showed several interesting and unexpected findings. First, regarding the change agent role perception, people who perceived themselves as advocates displayed a higher level of intention to learn business skills than did those who identified with the other two roles (i.e. traditionalist and facilitator). Second, when compared to extrinsic learning motivation, intrinsic learning motivation contributed more to the intention to learn business skills. Third, the study contributes to the literature by finding that, in terms of direction and magnitude, the two types of self-efficacy have similar influence on an IS developer’s behavioral intention to learn business skills. Finally, work support was found to have a positive impact on both extrinsic and intrinsic learning motivation. However, it was interesting to note that work support did not lead to significantly higher levels of relative and absolute learning self-efficacy.

The findings of this study provide several critical implications for practitioners seeking to encourage IS developers to learn b-skills. First, organizations should strongly encourage IS developers to take on the advocate role in ISD projects, and urge them to acquire business skills through formal education and on-the-job training. Second, organizations should also help IS developers understand how learning business skills is important for their future work and potential self-growth, rather than focusing solely on extrinsic benefits such as promotion or remuneration. Third, organizations can also make use of the strategies to enhance IS developer’s learning self-confidence and beliefs, which will, in turn, increase their intention to learn business skills. Finally, support from others is influential in the formulation of positive work attitudes and behaviors, so organizations will benefit when employees are well supported.

While prior research has emphasized the importance of business skill possession for IS developers during the system development process, few studies have explored the factors affecting an IS developer’s behavioral intention to learn those business skills. This study intends to bridge this gap by investigating factors that drive IS developers’ intention to learn business skills. The findings of this study are useful to researchers in the development and testing theories related to IS developer learning behavior, and to practitioners to facilitate business skill learning for their IS development staff.

The manager of the 21st century is expected to succeed in an environment strongly characterized by unprecedented volatility, uncertainty, complexity, and ambiguity (VUCA). In fact, today’s business environment consists of contradictory pressure and tensions, where competitive advantage could be gained by ambidextrous activities. The concept of ambidexterity has already been discussed by many scholars, but still little is known about managerial practice and actions that are useful for finding the balance between the paradoxes that have been identified at that level. Although there are different tensions, dynamic and evolving according to the changes observed in the environment: more volatile, uncertain, complex, and ambiguous, the pressure to remain flexible and simultaneously maintain the plan of development, seems to be essential. In recent research studies, networking perspective is mentioned as one of areas worth exploring while analyzing the concept of ambidexterity. For that reason, the main goal of this chapter is to investigate if networking is one of the factors useful for managing ambidexterity. To gain deeper insight, we investigated further, searching for the factors essential for managing ambidexterity: we compared the research results between companies of different sizes to identify any regularities. We focused on ambidexterity reflected by managerial practice where stability/plans and flexibility are implemented simultaneously. We investigated 150 managers using paper-and-pencil interviewing. Our research results confirmed that networking could be one of the main approaches having an impact on ambidextrous activities. However, we cannot conclude that companies are obliged to apply a networking perspective to be ambidextrous, although it could be recommended. Further analysis of companies of different sizes revealed the relationship between ambidexterity and networking in case of small and large companies, and no relation in medium-sized enterprises.

Fura is a traditional thick dough ball snack produced principally from millet or sorghum which is common in Nigeria. It is consumed with nono (local fermented milk) or mashed in water before consumption in the form of porridge. The purpose of this paper is to study the optimization of feed composition, feed moisture and screw speed on acceptability and hydration properties of fura extrudates from pearl millet and soybean flour mixtures.

The effects of extrusion conditions feed composition (ratio of soybean to millet), percentage moisture wet basis and screw speed (rpm) on the hydration properties and the acceptability of fura from millet‐soybean flour mixtures were studied using a single screw extruder. Response surface methodology (RSM) was adopted to evaluate the hydration properties responses of fura extrudates.

The models showed R²=0.863, 0.825, 0.898 and 0.741 for hydration power (HP), effect of quantity of water on swell volume (EQWSV), wettability (WTBLTY) and viscosity respectively indicating that the model was a good fit and could be used to navigate the design space. The result indicates that increasing the level of soybean flour resulted in decreased HP of fura extrudates. The overall acceptability sensory scores show that the fura extrudate design point 11 representing 20 percent soybean, 16.6 percent feed moisture and 200rpm recorded the highest acceptability (7.25) with significant differences from the other extrudates in terms of colour, flavor, texture and overall acceptability.

The extrusion cooking data from this study could help predict the expected performance in investigations of potential use of millet and soybean to explore the possibility of industrial projection.
