Abstract

Purpose

The purpose of this study is to propose an improved framework for managing Private Participation in Infrastructure ICT (PPI-ICT) projects in the context of developing countries as the requirements to manage them are different in several aspects.

Design/methodology/approach

The framework has been proposed based on an exhaustive literature review and statistical analysis of the PPI-ICT projects’ data set using logistic regression, F-test and student’s t-test. The proposed framework was also applied to the PPI-ICT projects.

Findings

The framework is an extension to NTCP (novelty, technology, complexity and pace) approach by including extrinsic factors such as income of the country, climate risk, religious diversity, political stability, regularity quality and control of corruption. The proposed framework was used to analyze project characteristics and their external conditions in the context of developing countries. Based on the analyses, the authors have presented a detailed set of recommendations for project managers, practitioners and governments to improve the success rate of these projects.

Originality/value

The major contribution of this study is the framework, which encompasses the NTCP model as well as extrinsic characteristics of PPI-ICT projects. The proposed framework is meant to assist the project managers to comprehend the project characteristics and its external environment to identify an adequate approach for managing projects successfully.

Abstract

Purpose

Additive manufacturing (AM) has been one of the most highlighted processes of the last few years. AM prints complex parts and items from 3D files regarding different materials, such as polymers. Moreover, there are different AM techniques available for polymers, such as selective laser sintering. In the SLS technology, polyamides 11 and 12 lead 88% of the market. These materials are high-cost and use an average of 50% of virgin material at each printing. It is possible to use lower rates of virgin material, but at least 30% is recommended. Low rates of virgin material decrease mechanical properties.

Design/methodology/approach

This study aims to evaluate the influence on the mechanical properties of the percentage of reused PA12 in parts manufactured by the SLS process. The specimens of PA12 were manufactured with a percentage of virgin/reused polymer of 50/50, 40/60, 30/70, 20/80 and 10/90. We considered three distinct printing directions to compare the mechanical properties of the specimens: horizontal, perpendicular and vertical.

Findings

The results showed that when the percentage of reused material increases, the tensile strength limit (TSL), flexural strength limit and Shore D hardness decrease. Another aspect visualized was the fragile behavior presented in the vertical specimens. In addition, DSC analysis indicated a 2% reduction of crystallinity. Scanning electron microscopy images revealed spherical voids and unfused particles of PA12 at the fracture of tensile test specimens. The material thermal history and unfused particles could decrease the material properties.

Originality/value

We observed that the mechanical properties, such as the TSL, flexural strength limit and hardness, decrease as the percentage of reused material increases. In addition, the process presented a printing-direction dependence, where the vertical direction presented as the more brittle between the ones used.

Abstract

Purpose

The purpose of this paper is to examine the effect of the intensive lifestyle modification program on weight and metabolic syndrome risk reduction in rural obese women who have no underlying non-communicable diseases in Thailand.

Design/methodology/approach

A randomized controlled trial was conducted. In total, 60 healthy obese women aged 30-50 years were recruited and randomly assigned to either the intervention (n=30) or control (n=30) group after health screening. Tailored nutritional counseling, health education and exercise training were included in the lifestyle modification program. Behavioral modification techniques were also incorporated. The intervention was conducted weekly for the first eight weeks, then biweekly until week 16.

Findings

The student’s t-test was used to compare mean difference between groups. The total weight loss in the intervention group (n=29) was significantly higher, 7.6±2.9 kg, compared with the control group (n=30) who lost 0.7±1.4 kg (p<0.001). The intervention group lost weight 10.2 percent from baseline which was significantly higher than that in the control group (p<0.001). Systolic and diastolic blood pressures, fasting blood sugar, and waist circumference were significantly improved. Triglyceride levels slightly improved while high density lipoprotein cholesterol was slightly lowered. The intervention group showed a statistical reduction in abnormal components of metabolic syndrome compared with the control group, with the relative risk=0.24, 95% confidence interval=0.072-0.791, and p=0.018.

Originality/value

Compatibility of the program activities conducted by a health professional who had achieved healthy weight loss and accepted as a role model was a key to achieving effective weight loss and metabolic syndrome risk reduction in obese women in rural areas. The program should be integrated into the conventional practice of health care centers.

Abstract

Purpose

Built upon three components (attitudes, subjective norms, and perceived behavioral control) of the theory of planned behavior (TPB), the purpose of this paper is to analyze the factors that influenced accounting students’ intention to pursue public accounting instead of private accounting as their career choice in China.

Design/methodology/approach

The TPB is used to predict the rational intention of accounting students in this study. A binary logistic regression analysis was applied to test all hypotheses because of its suitability.

Findings

The authors find that the variety and marketability of public accounting experiences, high turnover plus, low firm cohesion in the workplace, and perceived difficulties in traveling extensively affected students’ intentions to pursue the public accounting profession significantly. By highlighting these factors that affect students’ intention to pursue public accounting, this paper has important implications for the accounting educators and other stakeholders in China and other emerging economies.

Originality/value

By understanding the factors influencing the accounting students’ interests in pursuing public accounting, accounting educators and accounting firms could make some changes, redesign accounting curriculum, and enhance internship experience and recruiting process in order to increase more interests in public accounting. Professional organizations and policy makers might learn some lessons to take some actions to encourage young accounting professionals to work for public accounting firms. Moreover, this study has provided a valuable perspective to accounting educators, practitioners, and policy makers in other emerging economies with the same shortage of qualified public accountants.

Abstract

Purpose

Collective concepts of leadership open up some essential aspects of organizational leadership that could be defined as the collective ability of leadership to detect and cope with changes in the external environment by maintaining the primary goals of the organization. The purpose of this paper is to design a tool to evaluate organizational leadership capability.

Design/methodology/approach

A total of 445 respondents from six Estonian organizations participated by completing a questionnaire about organizational leadership. Next, a quantitative analysis is performed and sets of factors obtained from a partial least squares regression and Cronbach alpha test. Finally, the pattern of individual items (statements) within each of the factors is identified and the results, which indicate organizational leadership capability, are plotted.

Findings

During the last two decades, leadership on the collective level has come under greater focus. This has arisen from the necessity to transfer leadership capabilities to the strategic assets of organizations that allow them to achieve performance on a daily basis with long‐term success. That means organizational leadership capabilities that are based on the leadership skills and knowledge of organizational members on the one hand, and the extent to which these skills and knowledge are embedded in the structure of an organization on the other. Therefore, the measurement of organizational leadership capability is an important issue for improving organizational performance in the long term.

Originality/value

From the practical point of view, the measurement tool has many advantages: it is easier to collect answers from a large sample of respondents; it is simple to calculate and analyse the collected answers; it is also possible to measure organizations as a whole or by separate areas or management levels. Also, the measures in the measurement tool provide support to help managers increase the quality and efficiency of management in every day practice.

Abstract

Purpose

This paper aims to analyze the influence of organizational learning (OL) and service innovation (SI) on organizational performance of knowledge-intensive business services (KIBS) and examine the mediating role of SI.

Design/methodology/approach

Hypotheses were tested using the theoretical OL model of knowledge acquisition, distribution, interpretation and organizational memory (Huber, 1991; Lopez, Peon, & Ordas, 2005; Jiménez-Jiménez & Sanz-Valle, 2011), using structural equation modeling partial least squares analysis of a survey data set of Brazilian architectural firms.

Findings

Findings suggest that OL is significantly linked to SI and so is SI to organizational performance. However, neither the direct relationship between OL and organizational performance could be verified, nor the mediating effect of SI.

Practical implications

These results can offer KIBS managers insights that suggest that OL alone does not guarantee a significant impact in organizational performance, but it is a starting point for achieving SIs, that lead to performance improvement and competitive advantages.

Originality/value

This paper contributes to the knowledge production in the following ways: to the understanding of the relationship between OL and SI and its effect on organizational performance, traditionally overlooked in the literature; to the study of SIs, considering the importance of the service sector; and to the study of innovation processes in architectural firms, a sector traditionally understudied, because of the focus on large construction firms.

Abstract

Purpose

The objective of this work is to prepare two complementary diets based on the enrichment of the traditional Ogi with soybeans and crayfish and comparatively evaluate the compositional and sensory attributes of the two diets.

Design/methodology/approach

The diets were formulated by mixing Ogi with soybean flour in the ratio of 7:3 to produce diet A, and with the crayfish flour in the same ratio, giving rise to diet B. These diets were evaluated for their nutritive value using proximate analysis. Sensory evaluation was also carried out to assess the acceptability of the diets.

Findings

Chemical analysis showed that diet A (Ogi‐soybeans) contained 14.16 per cent protein, 18.6 per cent fat, 2.0 per cent crude fibre and 2.14 per cent ash, while diet B (Ogi‐crayfish) contained 17.66 per cent protein, 12.6 per cent fat, 2.45 per cent crude fibre and 5.35 per cent ash. Sensory evaluation showed that diet A was generally more acceptable in terms of colour, tastes, consistency and aroma. However, this difference was not statistically significant (p<0.05).

Originality/value

The methods employed in this study are very simple and ingredients used are available and acceptable to local tastes. Both prepared diets, in their present form, are compared favourably with industrially prepared Nutrend. It is therefore possible for small‐scale and cottage industries to engage in suitable complementary food production in Nigeria, utilizing local resources.

Abstract

Purpose

The purpose of this paper is to explore creativity and how it changes over time among engineering students in practice-based entrepreneurship in higher education. This change was examined in students over a one-semester course in entrepreneurship. Entrepreneurship courses that use creativity tools for practice-based learning are expected to develop creativity as a learning outcome. This study discusses the extent to which some learning outcomes are more easily developed than others.

Design/methodology/approach

This research uses a longitudinal design by applying a pre- and post-test survey. The student population consists of engineering students enrolled in an entrepreneurship course with practice-based learning involving creativity tools. The course includes team-based idea generation and business model development. To measure actual changes in students’ creativity, two measures were used to reflect different aspects.

Findings

The results show that students’ ability to perform creative tasks increased, while students’ willingness to engage in and their enjoyment of creative tasks decreased as a result of the course. Non-significant differences in changes were found between the two measures, but a difference was found in how the two measures changed during the course. In line with the research question, the results suggest that education may influence ability to a greater extent than willingness.

Originality/value

The research used two different creativity measures to explore the extent to which engineering students experienced a change in creativity over a one-semester entrepreneurship course. In this way, the research contributes to the discussion on what could be learnt and by what means.
