This study aims to address a deep statistical analysis on transtibial prostheses made of composite isogrid carbon/epoxy structure.

For the methodological procedure, an experimental arrangement was created using design of experiments, and the response surface methodology (RSM) was used. The RSM was obtained from the decision variables of the isogrid model, which consists of angle, circular width and helical width. All modeling was performed numerically using the finite element method.

Results obtained through analysis of variance (ANOVA) indicated the sensitivity of each decision variable (manufacture) in the mechanical responses. The results obtained in this study provide a starting point in formulating optimization problems for researchers and engineers.

A noteworthy thing about structural analysis and structural optimization is that some parameters and decision variables are more significant than others in certain responses (Major et al., 2011). Knowing the sensitivity of these parameters is essential for the correct formulation of an optimization problem. To handle these obstacles, design of experiments and ANOVA are used to solve and obtain the main effects on the structural performance. Nevertheless, to the best of the authors’ knowledge, very few efforts have been devoted to the development to show the factors that influence the various responses of a lower limb prosthesis isogrid tube.

This paper is an attempt to explore the relevance and usefulness of accounting education to development needs of LDCs; and to make constructive suggestions for educational change in any areas where relevance or usefulness seem to be very seriously deficient Identification of development needs is discussed first, then the present character of accounting education as exported to LDCs is discussed in the context of development needs. Finally strategic proposals are made to close the largest gaps between development need and the supply of accounting education.

The purpose of this paper is to provide an integrative picture of the state of the art of the literature on digitalisation of small and medium-sized enterprises (SMEs) as an enabler for their internationalisation process and as a comprehensive view of the specific domains impacted by digital technologies as well as their repercussions on the international outreach.

A systematic review which leverages a descriptive analysis of extant literature and an axial coding technique has been conducted to shed light on the current knowledge and to identify primary research areas and future research lines.

The research indicates that digitalisation impacts the internationalisation of SMEs in three specific domains: (1) internationalisation through the adoption of information and communication technologies (ICT) technologies and e-commerce platforms; (2) international expansion through the digitalisation of value chain activities and (3) international outreach through knowledge acquisition on digital platforms.

The value of this study is threefold. First, the authors attempt to systematically review the literature on SMEs digitalisation and internationalisation and provide a holistic perspective on the intertwining of these two research streams. Second, the authors propose a novel conceptualisation on the dimensions of SMEs digitalisation as enablers to internationalisation. Third, the authors put forward promising future lines of research.

1. Digitalisation represents a pivotal strategy that allows companies to build new strategic capabilities and is a propeller for SMEs internationalisation.

2. Through e-commerce, SMEs could compete at the same level of multinational companies but enduring lower costs of expansion.

3. Digital platforms allow SMEs to enhance the learning processes about international markets through an immediate access to relevant information.

4. Digital entrepreneurship has enabled SMEs to develop new configurations of value chain activities, evolving their business model or reaching new markets.

5. SMEs are changing the “business as usual” paradigm offering digital tools to build modular architectures that are scalable and agile in their evolution ability.

The role of patient’s characteristics in the prescribing decision of physicians comprises two major constructs: drug request and expectations. The purpose of this paper was to examine the existing literature on patient characteristics and then explore the circumstances that reinforce the connection between patient characteristics (drug requests and expectations) and physician prescribing decision.

A survey of the literature was carried out across online databases from 1994 to 2015, and 25 reviewed articles were identified. The influence of patient factors on physician prescribing decisions was identified in the articles. A conceptual model to investigate the patient characteristics that influence physicians’ prescribing decision was the developed.

There have been numerous studies on the effect of patient characteristics on physician prescription decision. Some studies discovered patient’s request for drug and expectations strongly influence physicians’ prescribing decision, whereas others found only minor or no relation. To resolve this ambiguity, there is a need to precisely understand how patient factors affect prescribing decisions of physicians, under different contexts and conditions. This review contends that contextual variables – drug characteristics, drug cost/benefits ratio and physician habit persistence – are determining factors in this debate.

The study recommends further studies on the influence of each factor on physician prescribing behaviour and an evaluation of the proposed model and moderating variables.

This paper is the first significant step towards recognizing contextual variables that may moderate the relationship between a patient’s drug request and expectations and prescribing behaviour. This research contributes to resolving the debate on the ways patient factors affect prescribing behaviour.

The present paper aims at the multi-objective optimization of a reentrant hexagonal cell auxetic structure. In addition, a parametric analysis will be carried out to verify how each of the design factors impact each of the responses.

The multi-objective optimization of five different responses of an auxetic model was considered: mass, critical buckling load under compression effort, natural frequency, Poisson's ratio and failure load. The response surface methodology was applied, and a new meta-heuristic of optimization called the multi-objective Lichtenberg algorithm was applied to find the optimized configuration of the model. It was possible to increase the failure load by 26.75% in compression performance optimization. Furthermore, in the optimization of modal performance, it was possible to increase the natural frequency by 37.43%. Finally, all 5 responses analyzed simultaneously were optimized. In this case, it was possible to increase the critical buckling load by 42.55%, the failure load by 28.70% and reduce the mass and Poisson's ratio by 15.97 and 11%, respectively. This paper addresses something new in the scientific world to date when evaluating in a multi-objective optimization problem, the compression and modal performance of an auxetic reentrant model.

It was possible to find multi-objective optimized structures. It was possible to increase the critical buckling load by 42.82%, and the failure load in compression performance by 26.75%. Furthermore, in the optimization of modal performance, it was possible to increase the natural frequency by 37.43%, and decrease the mass by 15.97%. Finally, all 5 responses analyzed simultaneously were optimized. In this case, it was possible to increase the critical buckling load by 42.55%, increase the failure load by 28.70% and reduce the mass and Poisson's ratio by 15.97 and 11%, respectively.

There is no work in the literature to date that performed the optimization of 5 responses simultaneously of a reentrant hexagonal cell auxetic structure. This paper also presents an unprecedented statistical analysis in the literature that verifies how the design factors impact each of the responses.

Notes that quality management practices of leading firms have increasingly been considered benchmarks for other companies in quest of successful competitive technologies. Shares the most relevant findings of the authors’ study on key quality practices of leading firms in Brazil. Includes comparisons with results of research in the USA. Identifies socio‐cultural factors as a root‐cause for the difficulties of employing these practices effectively in Brazil. Recommends the development of innovative capabilities and cultural synergies, in the scope of the increasing associations with foreign firms, to overcome at least some of the difficulties at issue.

The purpose of this paper is to identify, assess and explore potential risks that Chinese companies may encounter when using, maintaining and enhancing their enterprise resource planning (ERP) systems in the post‐implementation phase.

The study adopts a deductive research design based on a cross‐sectional questionnaire survey. This survey is preceded by a political, economic, social and technological analysis and a set of strength, weakness, opportunity and threat analyses, from which the researchers refine the research context and select state‐owned enterprises (SOEs) in the electronic and telecommunications industry in Guangdong province as target companies to carry out the research. The questionnaire design is based on a theoretical risk ontology drawn from a critical literature review process. The questionnaire is sent to 118 selected Chinese SOEs, from which 42 (84 questionnaires) valid and usable responses are received and analysed.

The findings identify a set of 40 ERP exploitation risks, which concentrate around operational, analytical, organisation‐wide and technical issues. The top ten identified ERP risks and associated causes and consequences are discussed extensively in this paper. The study also explores and identifies ten statistical correlations between the risks identified.

This study contributes to the knowledge of ERP in general, and provides valuable insights into ERP exploitation risks in Chinese SOEs in particular.

The findings can be used by practitioners for the management and prevention of potential risks in ERP post‐implementation.

The need for the research emerges from the growing awareness in the field that there is a scarcity of studies focusing on ERP post‐implementation, in contrast with an over‐abundance of studies focusing on implementation and project management aspects.

Drawing insights from the culture-centered approach (Dutta-Bergman, 2004; Dutta, 2007), the purpose of this paper is to explore the meanings of, experiences with, and information sources for antibiotics among at-risk yet understudied populations in urban and economic margins in the Global South.

Given the exploratory purpose of this paper, it used qualitative approach specifically focus group discussions with mothers, guardians and female senior citizens from Manila, Philippines.

Antibiotics had multiple meanings – from purposes and modes of acquisition to side-effects. Experiences with antibiotics were not only tied to financial difficulties, but also in administering antibiotics to children or wards and managing side-effects. Furthermore, medical doctors were the most accessed and preferred sources of antibiotics-related information.

To date, this paper is one of the few to argue that knowing the conditions into which antibiotics are situated in the Global South is critical for strengthening global public health campaigns and policies against antimicrobial resistance a and reducing global health inequity.

This study aims to investigate the relationship between university–industry collaboration (U-I-C) in research and development (R&D) and quality management and explore how the relationship is mediated by innovation.

Based on panel data consisting of 109 countries spanning over a five year period (2013-2017) this study investigates, through structural equation modelling, how this relationship is mediated by innovation.

The main finding is that there are positive significant direct effects between U-I-C and innovation and between innovation and international organization for standardization (ISO) 9001. Furthermore, the strength and significance of these relations are highly affected by the classification of income in these countries, which ranges from high and upper-middle to lower-middle categories. This paper concludes that countries in the high-income category have higher achievement in U-I-C in R&D, innovation and ISO 9001 when compared to the upper and lower-middle-income categories.

This paper demonstrates in the empirical study the value of collaboration in R&D between government, industry and academia, as it can encourage scientific research and contribute to quality management and innovation. This research is one of the very few studies to assess the country’s income classification effect on U-I-C in R&D, innovation and ISO 9001. It is recommended that more research is conducted on how countries not ranked in the high-income category could benefit from U-I-C in R&D to enhance innovation and quality management.

The purpose of this paper is to explore the development of knowledge sharing from the perspectives of broaden-and-build theory and expectancy theory. Its research purpose is to understand how knowledge sharing is driven by such predictors as optimism, pessimism, and positive affect through their complex interactions with collectivism or power distance. In the proposed model of this study, knowledge sharing relates to optimism and pessimism via the partial mediation of positive affect. At the same time, the influence of optimism, pessimism, and positive affect on knowledge sharing are moderated by the national culture of collectivism and power distance, respectively.

This study’s hypotheses were empirically tested using data from high-tech firms across Taiwan and Malaysia. Of the 550 questionnaires provided to the research participants, 397 usable questionnaires were collected (total response rate of 72.18 percent), with 237 usable questionnaires from Taiwanese employees and 160 usable questionnaires from Malaysian employees. The data from Taiwan and Malaysia were pooled and analyzed using: confirmatory factor analysis for verifying data validity, independent sample t-tests for verifying the consistency with previous literature regarding cultural differences, and hierarchical regression analysis for testing relational and moderating effects.

This study demonstrates the integrated application of the broaden-and-build theory and expectancy theory for understanding optimism, pessimism, and positive affect in the development of knowledge sharing. The test results confirm that positive affect partially mediates the relationship between optimism and knowledge sharing and fully mediates the relationship between pessimism and knowledge sharing. Moreover, collectivism and power distance have significant moderating effects on most of the model paths between knowledge sharing and its predictors except for the relationship between pessimism and knowledge sharing.

This study extends the expectancy theory to justify how optimistic and pessimistic expectations are stable traits that dominate the way employees share their knowledge sharing. This study shows how collectivism and power distance of Hofstede’s cultural framework can be blended with the broaden-and-build theory and expectancy theory to jointly explain knowledge sharing. Besides, this study provides additional support to the adaptation theory of well-being that suggests psychosocial interventions, which manage to enhance well-being by leveraging positive affect, hold the promise of reducing stressful symptoms and boosting psychological resources among employees.
