Abstract
Purpose
Population aging was a global trend, and the most obvious thing after aging was the change in skin appearance. Therefore, the active ingredients that delay skin aging were particularly noticed. Past studies had pointed out that Chinese herbal extracts can improve skin elasticity, reduce wrinkles and melanin precipitation. The purpose of this paper is to explore whether combining hydrolyzed collagen with Chinese herbal extracts can improve skin conditions and achieve anti-inflammatory effects.
Design/methodology/approach
Fifty subjects were randomly divided into collagen or placebo groups, and one bottle of collagen or placebo drink was used every day for four weeks, after which skin and inflammatory factors were tested.
Findings
In comparison with the baseline results, the skin parameters were improving after four-week intervention. In addition, the IL-6, IL-8, TNF-a were significantly decreased and tissue inhibitor matrix metalloproteinase 1 (TIMP-1) was increased after four-week hydrolyzed collagen intervention.
Originality/value
This study showed that hydrolyzed collagen combined with Chinese herbal extracts can improve the condition of the skin, and can also reduce inflammatory associated factors, thereby achieving anti-aging effects.

Abstract
Purpose
This paper aims to propose an integrative and result-driven health-care knowledge management (HKM) model and discuss the findings of a research that examines how the KM initiatives of a major private Brazilian hospital system are linked to its health-care performance outcomes.
Design/methodology/approach
Data were collected from a top-level Brazilian private hospital system (Mater Dei Healthcare System – MDHS), which is composed of three large hospitals internationally accredited by ISO 9001/2000, NIAHO and JCI. Multiple qualitative approaches were used to collect data such as 16 in-depth interviews with health professionals and managers, document analysis, participatory observation and benchmarking interviews with two reference hospital networks in Brazil.
Findings
The proposed health-oriented KM model is an expansion of the organizational knowing cycle model (Choo, 1996), adding absorptive capacity (ACAP) as a new construct. The paper discusses how ACAP integrates with sense-making, knowledge creation and decision-making processes within the health-care context. Information technology and clinical governance were identified as support factors to the HKM processes.
Practical implications
The paper presents a pragmatic and result-driven knowledge management (KM) model using health-care-welfare key performance indicators, as well as the emergence of KM as an integrative and strategic approach to hospital management.
Originality/value
The present study presents a knowledge-based perspective to clinical staff management, demonstrating the tangible results of KM initiatives that contribute to health and management performance outcomes.

This study empirically tests the impact of the Dark Triad personality traits (narcissism, Machiavellianism, psychopathy) and co-worker competitiveness on knowledge sabotage.
Abstract
Purpose
This study empirically tests the impact of the Dark Triad personality traits (narcissism, Machiavellianism, psychopathy) and co-worker competitiveness on knowledge sabotage.
Design/methodology/approach
A model was constructed and tested by means of Partial Least Squares with data from 150 participants recruited via Amazon’s Mechanical Turk.
Findings
The individual personality traits of narcissism, Machiavellianism, and psychopathy are significant predictors of individual knowledge sabotage behavior, whereas co-worker Machiavellianism and psychopathy trigger co-worker knowledge sabotage. Out of the three Dark Triad traits, individual and co-worker psychopathy emerged as the strongest knowledge sabotage predictor. Co-worker competitiveness has a positive effect on co-workers’ knowledge sabotage behavior. There is a relatively strong relationship between co-worker and individual knowledge sabotage which suggests that knowledge sabotage is a form of contagious workplace behavior. Individuals underestimate their negative behavior and traits and/or overestimate those of their fellow co-workers.
Practical implications
Managers should realize that the Dark Triad personality traits could predispose certain individuals to engage in extremely harmful counterproductive knowledge behavior. They need to ensure that individuals with these traits are not hired or are identified during their probation periods. It is recommended that organizations include knowledge sabotage measures in their periodic employee surveys. Organizations should help their employees objectively re-evaluate their own traits and knowledge behavior as well as those of their colleagues to ensure that their reciprocating knowledge behavior is more aligned with the reality in their organization.
Originality/value
This study offers a reliable and valid quantitative survey instrument to measure the presence of knowledge sabotage.

Abstract
Purpose
The purpose of this study is to understand the effect of different brand positions (underdog vs top dog) and comparative advertising on consumers’ brand attitudes. Additionally, this study also aims to demonstrate the effects of inspiration, self-relevance and empathy on the relationship between brand positioning and comparative advertising.
Design/methodology/approach
A two-by-three factorial design was employed with brand positions (underdog vs top dog) and three types of comparative advertising (noncomparative, indirect comparative and direct comparative) as the independent variables. Inspiration serves as the mediator, while self-relevance and empathy act as moderators and brand attitude is the dependent variable.
Findings
The results show that different brand positions significantly affect brand attitudes, with respondents having a better brand attitude toward the underdog brand. Brand attitude is partially mediated by inspiration. Self-relevance moderates the relationship between brand positioning and brand attitude. However, brand positioning, comparative advertising and empathy do not have interaction effects.
Research limitations/implications
This study contributes to a better understanding of the effect of psychological variables on brand positioning and comparative advertising.
Practical implications
The results suggest that the underdog setting requires a real and honest story because consumers will spot a fake underdog story, which will damage consumer trust in the brand and harm the brand image.
Originality/value
There is a lack of research using psychological variables to demonstrate the effect of being the underdog brand. This study contributes to the literature by employing psychological variables to illustrate the effect of underdog positioning. These findings can help brands develop branding positioning strategies.

The purpose of this paper is to understand middle class household food providers’ attitudes to the regulation of food marketing and the promotion of healthy food practices.
Abstract
Purpose
The purpose of this paper is to understand middle class household food providers’ attitudes to the regulation of food marketing and the promotion of healthy food practices.
Design/methodology/approach
A cross-sectional, online questionnaire survey was administered to 3,925 urban respondents in Indonesia, Melbourne, Shanghai, Singapore and Vietnam. Cross-tabulation, confirmatory factor analyses and multiple regression analyses were employed.
Findings
Most respondents supported government communications to promote healthy eating and to a lesser extent, regulatory measures to control unhealthy food marketing. Personal values and country of residence were more strongly associated with the respondents’ views than demographic variables. Overall, strongest support for nutrition promotion and for stricter regulation of food marketing was seen in Shanghai, Indonesia and Vietnam. Broadly, two groups were identified across the region: those who held equality-nature or tradition-security-conformity personal values, who disapproved of food marketing but supported government health promotion campaigns, and, those with stronger hedonist values who held opposite views.
Research limitations/implications
First, a wider range of personal values could be included in future studies to better represent Asian values. Second, changes in population views could be assessed in future longitudinal studies. Finally, future studies should include dietary assessments and the views of people from a variety of socio-economic and cultural backgrounds.
Practical implications
These findings suggest that health policy makers and communicators need to frame their communications to match the world views of household food providers in their countries.
Originality/value
The study provides confirmation of attitude-values theories within five different countries in the Asia Pacific region and demonstrates the importance of personal values and country of residence in influencing food providers’ views.

Abstract
Purpose
Understanding people’s intentions to be an internet entrepreneur is an important issue for educators, academics and practitioners. The purpose of this paper is to develop and validate a scale to measure internet entrepreneurial self-efficacy.
Design/methodology/approach
Based on an analysis of 356 responses, a scale of internet entrepreneurial self-efficacy is validated in accordance with established scale development procedures.
Findings
The internet entrepreneurial self-efficacy scale has 16 items under three factors (i.e. leadership, technology utilization and internet marketing and e-commerce). The scale demonstrated adequate convergent validity, discriminant validity and criterion-related validity. Nomological validity was established by the positive correlation between the scale and, respectively, internet entrepreneurship knowledge and entrepreneurial intention.
Originality/value
This study is a pioneering effort to develop and validate a scale to measure internet entrepreneurial self-efficacy. The results of this study are helpful to researchers in building internet entrepreneurship theories and to educators in assessing and promoting individuals’ internet entrepreneurial self-efficacy and behavior.

Abstract
Purpose
The purpose of this paper is to analyze the wastewater discharge and a zero-wastewater-discharge (ZWD) reproduction plan is designed for a paper mill in Taiwan.
Design/methodology/approach
The proposed model of ZWD reproduction planning is established using the fuzzy comprehensive evaluation and Taguchi method to determine the overall wastewater recovery rate. Still the prior studies failed to address a systematic approach to optimize the waste water recovery rate.
Findings
The optimal solution for clean water is 500 tons, recovery electrodialysis reversal is 345 tons, the wastewater reuse performance is 1.3 and waste heat recycling performance is 0.8, the larger number is performed well. The results shows that the maximum overall waste water recovery rate is 97.8 percent.
Originality/value
A paper mill is strived for improving their sustainable development. In real situation, there is a need to address the qualitative information and qualitative data to carry out the optimal ZWD reproduction planning.

Abstract
Purpose
The purpose of this work is to comprehensively reveal the spatial distribution and evolution features of a running-in attractor.
Design/methodology/approach
The friction coefficient signals extracted from wear experiments are reconstructed. A projected matrix is obtained based on the reconstructed matrix. Then the approach of three-dimensional (3D) histogram of phase points is proposed, which is used to intuitively characterize the complex properties of the running-in attractor.
Findings
The space occupied by the running-in attractor gradually contracts, then stabilizes and finally expands; the maximum of phase points number in a certain bin initially decreases, then keeps stable and finally increases rapidly; yet the percentage of bins number storing phase points shows an inverse variation tendency. Consequently, 3D histogram evolves from a nonuniform state to a uniform state then returns back to the nonuniform state, which indicates the evolution rule of “formation, stabilization and disappearance” of the running-in attractor.
Originality/value
Characterization on the features of the running-in attractor can provide valuable information about friction systems and their dynamic behaviors.

Abstract
Purpose
This study aims to investigate how the processes of memory acquisition, retention, retrieval and application occur in project-based organizations (PBOs). In this kind of organization, the nature of corporate memory is influenced by the transience, uniqueness and independence of the project portfolio. Such understanding may help practitioners to mitigate the effects of project transience and promote knowledge sharing among project teams.
Design/methodology/approach
An empirical and qualitative study was carried out through a multiple case study approach conducted in three Brazilian Engineering Design Firms, which are organized by projects. Document analysis, direct observation and semi-structured interviews with engineers, project managers and executives were conducted.
Findings
The memory acquisition process takes place in five forms which have different sources and destinations when comparing PBOs with traditional organizational settings. Memory retention in PBOs crosses organizational boundaries and establishes a knowledge network of former employees and third parties. The PBOs project memory can be divided into volatile and perennial memory, where the former can be lost throughout project execution and the latter is internalized, becoming an inseparable part of the corporate memory. Memory retrieval in PBOs is also distinct since it has particular mechanisms depending on whether the knowledge is technical or administrative.
Originality/value
The research investigates the corporate memory processes within the volatile context of PBOs in a Latin-American developing country whose culture favors tacit knowledge exchange. The paper proposes a framework that unveils different patterns of knowledge acquisition, temporary and perennial retention structures, intensive usage of external knowledge in memory retrieval and particular memory applications in PBOs. The framework may guide scholars, project managers, engineers and practitioners in navigating through the uniqueness of organizational learning flows and structures in PBOs.

Abstract
Purpose
The purpose of this paper is to propose a cradle-to-cradle (C2C) zero discharge production planning system with a fuzzy hybrid optimization model that uses fuzzy comprehensive evaluation to establish fuzzy indicators, and then defuzzify the fuzzy indicators to construct a fuzzy multiobjective programming (FMOP) model.
Design/methodology/approach
The FMOP model pursues overall satisfaction using a particle swarm optimization algorithm to produce the best output values for the maximum waste paper recovery rate, the condensate reuse quality and minimum total cost of the zero discharge production planning system.
Findings
Recovered waste heat is seldom recycled and consumed in Taiwan. There is a need to capture and utilize heat recovery and use it in the production process supply. In contrast, waste materials are used as resources to perform waste paper recovery and recycle the waste heat of evaporation collection in the production process.
Originality/value
This paper develops a system to establish the best output value for an overall high satisfaction level. According to the results, the waste paper recovery rate is 99.8 percent, condensate reuse quality water is 102.6 tons and the total cost of the zero discharge production planning system is NT$1,312,012.
