Several post-disaster housing extension and modification studies have indicated that owner-driven modification behavior relates to socio-economic and livelihood factors. This study aims to clarify housing extension patterns and examine the relationships among spatial characteristics, sociocultural factors, livelihood factors and housing extensions. This research also highlights the implications of post-disaster housing design for indigenous communities.

An indigenous community case study was conducted using a literature review. Moreover, interview surveys and housing measurements were implemented based on purposive sampling to diversify interviewees’ backgrounds and the extent of housing extensions.

This study confirms that housing extensions are closely related to the number of household members and their associated functions and cultural and livelihood factors that were ignored during the design stage. Furthermore, the housing extension process was confirmed to match households’ economic recovery. A post-disaster housing implementation framework for the indigenous population is proposed.

This research only targeted one indigenous community with a limited number of interviewees and samples because of the connection with households.

The study’s proposed resilience post-disaster housing framework can be used to develop post-disaster housing design guidelines, which can benefit policymaking. The proposed participatory concept can be further adopted in future disaster risk-reduction programs.

This study uniquely focuses on the pre- and post-disaster housing layout and the livelihood of an indigenous community. It offers valuable insights for post-disaster reconstruction planners and practitioners.

The purpose of this paper is to advance knowledge about organization‐public relationships by establishing a theoretical category for understanding them and by contributing to a foundation of knowledge in that category. Relationship stresses are presented as the factors that constrain organization‐public relationships. This study identifies stresses on the relationship between a grassroots advocacy organization and its former members, as well as stresses between the organization and members who have decreased their participation in it.

In‐person interviews were conducted with 24 people, phone interviews were conducted with 44 people, and e‐mail interviews were conducted with 13 people. Interviewees included staff members, former volunteers, and volunteers who had decreased their participation in the organization.

Several relationship stresses were identified: the silver curtain, the emotion tax, relationship speeding, invisible isms, weak leadership, disagreement with decisions, the revolving door, overworking volunteers, underworking volunteers, age, and health.

This study contributes a new category for relationship management scholarship, which can be productive for theory building. It also illuminates Dozier and Lauzen's questioning about the unique conditions of social movement organizations.

Established cultivation strategies can actually aggravate publics when a relationship has significantly deteriorated and the root problem is not addressed.

Recognizing problems in the relationship between an advocacy organization and members results in a deep understanding of a unique context for public relations practice. In addition, this study illuminates a context for cultivation strategies by codifying a foundation of relationship stresses. Identifying stresses to relationships can help scholars and practitioners ascertain problems and treat those problems at the root level.

This study seeks to investigate strategies for building personal relationships with an organization's members, and to examine the outcomes of personal relationships in an advocacy organization.

The case study includes interviews with 39 staff people at national, state, and affiliate levels of the organization; 58 members; and five former members, for a total of 102 participants. Document analysis and participant observation were supplemental methods.

The following strategies for cultivating personal relationships were identified: direct engagement, task sharing, constitutive rhetoric, peer linking, hat‐in‐your‐hand, investment in local relationships, and targeting of aware affiliates for diversity efforts. To contribute to the discussion about the value of personal relationships in organizations, the study also investigated the outcomes of personal relationships. The outcomes found in the study include affective commitment, political leverage, social capital, member recruitment, and member retention.

Although many of the cultivation strategies and outcomes are likely to apply to various contexts, some of them may be specific to the context of an advocacy organization that has a grass‐roots culture and layers of leadership, such as local, state, and national offices.

Organizations can read the study to identify potential strategies they can use to cultivate strong personal relationships with their stakeholders.

The study produces new cultivation strategies and outcomes for personal relationships and engages in a critical discussion of the existing literature.

Addressing the significant differences between referral programs and traditional promotional marketing, this paper aims to investigate and examine the impact of how reward-related information is presented within referral programs and how it interacts with reward size and reward allocation.

This study adopts framing effect and equity theory to build the relationship between reward presentation, reward size and reward allocation. Then, two scenario-based experimental studies are designed and conducted on Amazon Mechanical Turk.

The results show that there is no direct impact of reward presentation on referral likelihood, while the effect relies on reward size. As the levels of reward size increase, the referral likelihood gradually shifts from percentage form to dollar form as perceived size mediates the interaction effect on referral likelihood. Further, adding information about reward allocation also indicate the different impacts of equity and inequity on influencing the above findings.

The study contributes to the literature by introducing reward presentation and emphasizes its impact on individual’s behavior decisions in the context of referral programs. This study extends and broadens the scope and effectiveness of the framing effect on traditional promotional marketing strategies, while also bridging the gap in the literature by examining the combined role of information about rewards.

Security breaches have been arising issues that cast a large amount of financial losses and social problems to society and people. Little is known about how social media could be used a surveillance tool to track messages related to security breaches. This paper aims to fill the gap by proposing a framework in studying the social media surveillance on security breaches along with an empirical study to shed light on public attitudes and concerns.

In this study, the authors propose a framework for real-time monitoring of public perception to security breach events using social media metadata. Then, an empirical study was conducted on a sample of 1,13,340 related tweets collected in August 2015 on Twitter. By text mining a large number of unstructured, real-time information, the authors extracted topics, opinions and knowledge about security breaches from the general public. The time series analysis suggests significant trends for multiple topics and the results from sentiment analysis show a significant difference among topics.

The study confirms that social media monitoring provides a supplementary tool for the traditional surveys which are costly and time-consuming to track security breaches. Sentiment score and impact factors are good predictors of real-time public opinions and attitudes to security breaches. Unusual patterns/events of security breaches can be detected in the early stage, which could prevent further destruction by raising public awareness.

The sample data were collected from a short period of time on Twitter. Future study could extend the research to a longer period of time or expand key words search to observe the sentiment trend, especially before and after large security breaches, and to track various topics across time.

The findings could be useful to inform public policy and guide companies responding to consumer security breaches in shaping public perception.

This study is the first of its kind to undertake the analysis of social media (Twitter) content and sentiment on public perception to security breaches.

Focusing on the corporations in China and aiming to figure out the significant connection between organizational justice perception and job satisfaction from Chinese setting, this study aimed to examine the effects of organizational justice upon job satisfaction of the full-time and part-time employees in the state owned enterprise (SOEs) and primate Chinese companies.

The study adopted the questionnaire to investigate more than 300 employees, and the empirical data of this paper is based on statistical analysis, such as confirmatory factor analysis, correlational and regression analysis.

The paper arrives at the conclusion that in SOEs, the employees’ perception about procedural justice was higher than distributive justice. While in private enterprises, the procedural justice and interactive justice were tested to have similar coefficients. The relationship between organizational justice and job satisfaction differed between full-time employees and part-time employees.

This study opens a new window for understanding how organizational justice influences employees’ job satisfaction in Chinese context, taking a further step to explore the different impacts of organizational justice on job satisfaction among different types of employees.

This paper collected data from both SOE and private companies in China, increasing the external validity of the findings. Meanwhile, the authors observed consistent findings with the studies in Western Society, which increase the generalization of our findings as well. The findings highlight the value of integrating literatures on organizational justice and job satisfaction.

This paper seeks to increase our understanding on the fluid mechanics and heat transfer in a transitional mixed convection flow between two vertical plates. Direct numerical simulation by the spectral method, with a weak formulation, is used to solve the transient 3–D Navier‐Stokes equations and energy equation. Initial disturbances consist of the finite‐amplitude 2–D Tollmien‐Schlichting wave and two 3–D oblique waves. The transition phenomena in a mixed‐convection flow can be significantly different from the isothermal flow. Disturbance competitions among different modes are also found to be different from those known for an isothermal flow. In a mixed‐convection flow, there exist thresholds for the low‐mode Fourier waves. The intensified vortices are concentrated left of the central surface between the two plates. Hairpin vortices are formed with high Ri. Based on the flow visualization, the λ vortices are found to be staggered on the surfaces parallel to the plates. The Ri number seems to be the main parameter governing the transition mechanism. The Nu number is found to increase during transition.

To eliminate the angle deviation of magnetic encoder, this paper aims to propose a compensation method based on permanent magnet synchronous motor (PMSM) sensorless control. The paper also describes the experiments performed to verify the validity of this proposed method.

The proposed method uses PMSM sensorless control method to get high precision virtual angle value, and then get the deviation value between virtual position and magnetic angle which is used as compensation table. Oversampling linear interpolation tabulation method has been proposed to eliminate the noise signals. Finally, a magnetic encoder with precision (repeatability) 0.09° and unidirectional motion precision 0.03 is realized. The control system with an encoder running at 14,000 and 0.01 r/min showing high motion resolution is also realized.

Higher value of current in PMSM leads to a magnetic encoder with higher precision. When using oversampling linear interpolation to tabulate the compensation table, it is understood that more oversampling does not lead to a better result. Finally, validated by experiments, using eight intervals to calculate the mean value of angle deviation leads to the best result.

The angle deviation compensation method proposed in this paper has a great practical implication and a good commercial application. The method proposed in this paper could be effectively used to self-correct the magnetic encoder using arctangent method and also correct any rotary encoder sensor.

This paper originally proposes an adaptive correction method for a rotary encoder based on PMSM sensorless control. To eliminate the noise signals in an angle compensation table, over-sampling linear interpolation tabulation method has been proposed which also guarantees the precision of the compensation table.

The dispute over the benefit of diversity on the transactive memory system (TMS) has attracted the attention with the development of global collaboration. This paper aims to discover how knowledge heterogeneity (KH), categorized as explicit and tacit KH, affects TMS and to test the mediation effect of innovation climate (IC).

Data from a 6-month field study of 207 research and development (R&D) members and 7 expertize observers were analyzed by partial least squares structure equation model. Robustness check and Barron and Kenny mediation test were used to evaluate the model and confirm the mediation effect.

Tacit KH of R&D team negatively influences the development of TMS. Furthermore, IC partially mediates tacit KHs’ negative influence on the development of TMS.

These results distinguish the different influence of explicit and tacit KH on TMS and explore the mediating role of IC that has been confirmed affecting the development of TMS.

These results could motivate practitioners to address more attention to tacit KH, IC and the development of TMS in the R&D team members composition.

This study contributes not only to elucidate the different influence of explicit and tacit KH on TMS but also to the appropriate members composition of R&D team by considering the relationships among KH, IC, TMS and innovation performance.

The purpose of this study is to examine if the international experience of a family firm’s chairman, second-generation managers and other top managers all have impacts of different strengths using information about Chinese family firms’ international expansion.

Matching tactics and dynamic Heckman 2-stage analysis were applied to data on 766 publicly-listed Chinese family businesses covering 2008–2014.

The international experience of the chairman, second-generation family managers and other senior managers all were found to correlate with the proportion of a firm’s revenue earned abroad, as well as with the number of its cross-border mergers and acquisitions. The impact of a chairman’s international experience is stronger than the impact of the other two groups when internationalization is measured in terms of the proportion of revenue earned overseas. The second-generation managers’ international experience is the most influential when internationalization is measured in terms of the number of cross-border mergers and acquisitions.

This paper bridges agency theory with upper echelons theory in the context of the family business. The findings contribute to the scholarly understanding of family business by illuminating the mechanisms through which second-generation managers may influence family firms’ internationalization. They also enrich the knowledge of family firms in China.
