Abstract

Purpose

Studies have examined the influence of knowledge-sharing factors on attitudes and intentions to share knowledge; thus, there is a need to add to the limited research to examine individuals’ actual knowledge-sharing behaviour (KSB). Drawing upon the social cognitive theory (SCT) and transformational leadership, this study aims to develop a new research model which modifies the standard SCT model and augments it with other theories to examine academics’ KSBs.

Design/methodology/approach

Questionnaire surveys based on literature and pilot study were conducted with 785 academic staff from four Vietnamese public universities. This study applied structural equation modelling to test the proposed research model and hypotheses.

Findings

The findings show that environmental factors (subjective norms, trust) and personal factors (knowledge self-efficacy, enjoyment in helping others) had positive impacts on KSB; KSB had a strongly positive effect on innovative behaviour; and transformational leadership positively moderated the effects of subjective norms, trust and knowledge self-efficacy on KSB. Interestingly, psychological ownership of knowledge was found to have insignificant associations with KSB.

Practical implications

The study findings can be used by university leaders, academic staff and researchers in other similar contexts.

Originality/value

Until now, to the best of the researchers’ knowledge, no studies have applied SCT as a primary lens, in which transformational leadership positioned in a focal behaviour also affected KSB, to investigate research on KSB in organisations, especially in institutions of higher education.

The purpose of this paper is to measure TFP growth and job reallocation in the Vietnamese manufacturing industry after the Doimoi period.

Abstract

Purpose

The purpose of this paper is to measure TFP growth and job reallocation in the Vietnamese manufacturing industry after the Doimoi period.

Design/methodology/approach

The study uses firm-level panel data from Vietnam’s annual enterprise survey data for 2000–2016 period in the Vietnamese manufacturing industry using Olley–Pakes static and dynamic productivity decomposition methods.

Findings

The aggregate productivity estimated from the WRDG method increased 2.323 percent, of which over 40 percent is due to the reallocation toward more productive firms. Olley–Pakes dynamic decomposition according to ownership, scale and industry shows that the contribution of private and state-owned firms and the contribution of small and medium firms and large firms to the TFP growth are 133, −33 percent, 58.56 and 41.44 percent, respectively. The within-firm productivity and net entry components are the main reasons for TFP growth rather than reallocation. The results show that the composition of the aggregate TFPs, estimated from WRDG, OP, LP and ACF, is correlated very high (over 80 percent) except for net entry components.

Research limitations/implications

The major limitation of this study is that the authors compute an aggregate productivity index using actual employment-based shares (still misallocation in labor), rather than optimal employment-based shares (no misallocation in labor).

Originality/value

Job reallocation between industries is attracting attention in developing countries, especially transition economies. However, knowledge about job reallocation among industries is limited. This paper assesses the level of job reallocation among private and state-owned firms, small and medium firms and large firms in Vietnam.

Abstract

Purpose

Understanding the behavioral change process of system users to adopt safe security practices is important to the success of an organization’s cybersecurity program. This study aims to explore how the 7Ps (product, price, promotion, place, physical evidence, process and people) marketing mix, as part of an internal social marketing approach, can be used to gain an understanding of employees’ interactions within an organization’s cybersecurity environment. This understanding could inform the design of servicescapes and behavioral infrastructure to promote and maintain cybersecurity compliance.

Design/methodology/approach

This study adopted an inductive qualitative approach using in-depth interviews with employees in several Vietnamese organizations. Discussions were centered on employee experiences and their perceptions of cybersecurity initiatives, as well as the impact of initiatives on compliance behavior. Responses were then categorized under the 7Ps marketing mix framework.

Findings

The study shows that assessing a cybersecurity program using the 7P mix enables the systematic capture of users’ security compliance and acceptance of IT systems. Additionally, understanding the interactions between system elements permits the design of behavioral infrastructure to enhance security efforts. Results also show that user engagement is essential in developing secure systems. User engagement requires developing shared objectives, localized communications, co-designing of efficient processes and understanding the “pain points” of security compliance. The knowledge developed from this research provides a framework for those managing cybersecurity systems and enables the design human-centered systems conducive to compliance.

Originality/value

The study is one of the first to use a cross-disciplinary social marketing approach to examine how employees experience and comply with security initiatives. Previous studies have mostly focused on determinants of compliance behavior without providing a clear platform for management action. Internal social marketing using 7Ps provides a simple but innovative approach to reexamine existing compliance approaches. Findings from the study could leverage proven successful marketing techniques to promote security compliance.

Abstract

Purpose

The paper aims to sketch out the scenario of money laundering (ML) in Vietnam and the harm ML may cause to the country.

Design/methodology/approach

This paper first, based on the general concept of ML, scrutinizes actual and potential ML in Vietnam as well as ML threat to Vietnam. The typical cases of predicate offences, which were associated with ML activity, will be provided to illustrate the fact. Then a brief of Vietnam's response to ML will be examined.

Findings

ML has actually occurred since early in Vietnam. The potential for ML in Vietnam is substantial and poses growing harm to Vietnam in both the respects of economy and security. Although Vietnam has the primary legal framework of AML and set out AML countermeasures, the implementation has been hindered by several factors.

Originality/value

This paper would attract the attention of people who are concerned about ML in Vietnam.

This paper aims to evaluate the early effects of the pandemic of coronavirus disease 2019 (COVID-19) and accompanying stay-at-home orders on restaurant demand in US counties.

Abstract

Purpose

This paper aims to evaluate the early effects of the pandemic of coronavirus disease 2019 (COVID-19) and accompanying stay-at-home orders on restaurant demand in US counties.

Design/methodology/approach

The following two sets of daily restaurant demand data were collected for each US county: foot traffic data and card transaction data. A two-way fixed-effects panel data model was used to estimate daily restaurant demand from February 1 to April 30, 2020.

Findings

Results show that a 1% increase in daily new COVID-19 cases led to a 0.0556% decrease in daily restaurant demand, while stay-at-home orders were collectively associated with a 3.25% drop in demand. The extent of these declines varied across counties; ethnicity, political ideology, eat-in habits and restaurant diversity were found to moderate the effects of the COVID-19 pandemic and stay-at-home orders.

Practical implications

These results characterize the regional restaurant industry’s resilience to COVID-19 and identify particularly vulnerable areas that may require pubic policies and managerial strategies for intervention.

Originality/value

This study represents a pioneering attempt to investigate the economic impact of COVID-19 on restaurant businesses.

Abstract

Purpose

This paper aims to analyze the relationship between organizational culture (measured by mission, involvement, consistency, adaptability and well-being), employee organizational commitment and employee innovation in the Vietnamese IT industry.

Design/methodology/approach

This is a quantitative research using perceptual scale questionnaire survey developed based on the literature review and in-depth expert interviews. A total of 319 IT professionals working in Vietnam participated in the survey. The data were analyzed using multiple regression analysis.

Findings

The results suggest that overall organizational culture and organizational commitment are positively and significantly related to employee innovation. A closer look reveals that out of the organizational culture’s five dimensions, mission, adaptability and well-being are found specifically and significantly related to employee innovation.

Research limitations/implications

The study used a cross-sectional survey where case studies of longitudinal study may add more insight. Further, the Denison organizational culture survey instrument might be subjective. Finally, there may be also some moderating or mediating effects that are not taken into account in this study.

Practical implications

The enhancement of adaptability, well-being, mission and commitment can increase employee innovation in the IT industry.

Originality/value

This paper contributes to the literature and practice by demonstrating the relationship between corporate culture and organizational commitment on employee innovation in a developing country (i.e. Vietnam).

Abstract

Purpose

The purpose of this paper is to present a numerical analysis of the laser surgery of port wine stain (PWS) with cryogen spray cooling to compare the treatment effect between pulse dye laser and Nd:YAG laser, explain the incomplete clear of the lesion and optimize the laser parameter.

Design/methodology/approach

The complex structure of skin and PWS is simplified to a multi-layer skin model that consists of top epidermal layer and underneath dermis layer embedded with discrete blood vessels. The cooling effect of cryogen spray before laser firing is quantified by a general correlation obtained recently from the experimental data. The light distribution is modeled by the Monte Carlo method. The heat transfer in skin tissue is calculated by Pennes bioheat transfer model. The thermal damage of blood vessel is quantified by the Arrhenius damage integral.

Findings

For the vessel size studied (10-120 µm), pulse duration is recommended shorter than 6 ms. Large and deeply buried vessels, which may survive from 595 nm laser irradiation, can be coagulated by 1,064 nm laser due to its deep light penetration depth in skin. Furthermore, a desired uniform heating within the large vessel lumen can be achieved by 1,064 nm laser whereas 595 nm laser produce non-uniform heating.

Originality/value

The possible reason for the poor responding and incomplete clearance lesions is clarified. Laser wavelength and pulse duration are suggested to improve the clinical results.
