This monograph reports on the strategic and operational roles of learning and development (L&D) professionals in Irish, UK European and US organisations including multinational corporations, small to medium enterprises, the public sector and not for profit organisations. This paper aims to investigate the contextual factors influencing L&D roles in organisations, the strategic and operational roles that L&D professionals play in organisations, the competencies and career trajectories of L&D professionals, the perceptions of multiple internal stakeholders of the effectiveness of L&D roles and the relationships between context, L&D roles, competencies/expertise and perceived organisational effectiveness.

The study findings are based on the use of multiple methods. The authors gathered data from executives, senior managers, line managers, employee and L&D professionals using multiple methods: a survey (n = 440), Delphi study (n = 125) and semi-structured interviews (n = 30).

The analysis revealed that L&D professionals increasingly respond to a multiplicity of external and internal contextual influences and internal stakeholders perceived the effectiveness of L&D professionals differently with significant gaps in perceptions of what L&D contributes to organisational effectiveness. L&D professionals perform both strategic and operational roles in organisations and they progress through four career levels. Each L&D role and career level requires a distinct and unique set of foundational competencies and L&D expertise. The authors found that different contextual predictors were important in explaining the perceived effectiveness of L&D roles and the importance attached to different foundational competencies and areas of L&D expertise.

This is one of the few studies to have investigated the L&D professional role in organisations from the perspective of multiple stakeholders using multiple research methods.

Drawing on the motivation theory and family business literature, the purpose of this paper is to investigate the influence of family effect in growth behaviour of small-and-medium-sized enterprises (SMEs) in the UK.

The authors first compare the actual and expected growth of family and non-family-owned SMEs. The authors then compare the growth behaviour of small family firms managed by owner-directors and small family businesses co-managed by family and non-family directors with the non-family-owned SMEs.

The authors find a negative effect of family ownership on actual and intended small business growth behaviours. In addition, the findings also suggest that small family firms co-managed by non-family and family directors are no different from non-family-owned firms, in terms of reporting past actual growth in employment size and turnover as well as expecting growth in workforce size and turnover. The authors also observe a significant difference in anticipating sales growth between family-controlled and non-family-controlled firms. However, this difference is not explained by the heterogeneity of a top management team.

The study has important implications for managerial practice to family firms and on policies that improve the growth of SMEs. Specifically, the competence of managers and decision makers matters considerably in evaluating the efficient operation of the business and maximising the economic growth in SMEs.

The study makes two important theoretical contributions to small business growth literature. First, the findings underline a negative family effect in the actual and expected growth behaviour of SMEs. Second, the mode of family ownership alone may not sufficiently capture family effect and offer a thorough understanding of growth behaviour in SMEs.

Small businesses play a crucial role in national and local economies, but their problems are not always accorded the same importance as those of larger organisations. Research shows that many small businesses fail from lack of management ability. It has been argued that small businesses can improve their performance and increase their competitiveness with better information and decision support systems (DSS). Study of the few research papers available reveals that the current use of computers in small and medium‐size enterprises (SMEs) is often limited, and geared to operational support rather than managerial decision making. The work discussed in this paper investigated current DSS use in small manufacturing businesses in Bedfordshire, and canvassed the views of managers as to what additional support they most needed. Conclusions are drawn from the results of interviews with managers of six small manufacturing businesses and a large‐scale self‐report survey of Bedfordshire firms.

Online question-and-answer (Q&A) communities serve as important channels for knowledge diffusion. The purpose of this study is to investigate the dynamic development process of online knowledge systems and explore the final or progressive state of system development. By measuring the nonlinear characteristics of knowledge systems from the perspective of complexity science, the authors aim to enrich the perspective and method of the research on the dynamics of knowledge systems, and to deeply understand the behavior rules of knowledge systems.

The authors collected data from the programming-related Q&A site Stack Overflow for a ten-year period (2008–2017) and included 48,373 tags in the analyses. The number of tags is taken as the time series, the correlation dimension and the maximum Lyapunov index are used to examine the chaos of the system and the Volterra series multistep forecast method is used to predict the system state.

There are strange attractors in the system, the whole system is complex but bounded and its evolution is bound to approach a relatively stable range. Empirical analyses indicate that chaos exists in the process of knowledge sharing in this social labeling system, and the period of change over time is about one week.

This study contributes to revealing the evolutionary cycle of knowledge stock in online knowledge systems and further indicates how this dynamic evolution can help in the setting of platform mechanics and resource inputs.

Drawing on attribution theory, the current paper aims to examine the effects of review content structures on online review helpfulness, focusing on three pertinent variables: review sidedness, information factuality, and emotional intensity at the beginning of a review. Moreover, the moderating roles of reviewer reputation and review sentiment are investigated.

The review sentiment of 144,982 online hotel reviews was computed at the sentence level by considering the presence of adverbs and negative terms. Then, the authors quantified the impact of variables that were pertinent to review content structures on online review helpfulness in terms of review sidedness, information factuality and emotional intensity at the beginning of a review. Zero-inflated negative binomial regression was employed to test the model.

The results reveal that review sidedness negatively affects online review helpfulness, and reviewer reputation moderates this effect. Information factuality positively affects online review helpfulness, and positive sentiment moderates this impact. A review that begins with a highly emotional statement is more likely to be perceived as less helpful.

Using attribution theory as a theoretical lens, this study contributes to the online customer review literature by investigating the impact of review content structures on online review helpfulness and by demonstrating the important moderating effects of reviewer reputation and review sentiment. The findings can help practitioners develop effective review appraisal mechanisms and guide consumers in producing helpful reviews.

The rapid advancement in information and communication technologies (ICTs) has brought enormous business opportunities as well as challenges. One of these challenges is the demand for ICTs skills and expertise in adopting and implementing these emerging technologies. Coping with skills shortage poses a serious challenge across all European countries. Lack of ICTs skills and knowledge is more evident in small‐ and medium‐sized enterprises (SMEs). As training is regarded as the most effective way of improving skills and enhancing knowledge, this paper attempts to address skills shortage at pan‐European level by identifying SMEs’ needs on ICTs training in the UK, Portugal and Poland. The investigation focuses on the most needed training areas, the required training levels and the preferred training delivery channels. The paper summarises findings from three‐country investigations and highlights the implications of findings for the design and development of a Web‐based training system for the use of ICTs in SMEs.

The purpose of this paper is to present a transition detector (TD)-based radiation hardened flip-flop (TDRH-FF) for single event upset (SEU).

With SEU recovery and single event transient (SET) detector mechanism, the TDRH-FF can tolerate SEU during hold mode and generate a warning signal for architecture-level recovery during transport mode when input signal contains SET. Evaluation results show that the TDRH-FF outperforms comparable comprehensive performance.

Simulation results show that 1) the mean pulse width of the correction glitches (at full width half maximum) of TDRH-FF is less than 10 ps; 2) the area overhead of TDRH-FF is similar to the EVFERST-FF, BISER-FF and DNURHL-FF; 3) TDRH-FF has the same average power consumption as SETTOF, and moderate PDP and Ps values among these compared FFs.

In this paper, a TD-based TDRH-FF is proposed to solve the problems in the previous design. And the main contributions of the proposed TDRH-FF are summarized: Minimum size transistors are used in the proposed TD which leads to a considerable decrease in area overheads and propagation delay (resulting in an ignorable correction glitch); and compared with other radiation hardened flip-flop, TDRH-FF outperforms comparable comprehensive performance.

Building information modelling (BIM), lean construction (LC) and prefabricated housing construction (PHC) have individually aroused great attention from academia and industry. However, the integration of LC and BIM in PHC projects has not been sufficiently explored. This study aims to assess the current status of the implementation of BIM and LC in China’s PHC sector given, firstly, that China is a developing country characterised by the world’s largest population and a huge housing market, and secondly, that although China’s PHC is strongly supported by the government, the adoption of BIM and LC in PHC varies.

A mixed approach (questionnaire survey and interviews) is adopted in this study. A total of 127 valid questionnaires were collected. This is followed by interviewing 12 interviewees who are key stakeholders in PHC and hold managerial positions.

The findings of the questionnaire survey show that BIM is more prevalent than LC in PHC projects in China. In addition, the adoption of LC exhibits more maturity in stages associated with production and manufacturing, and logistics and transportation, whereas BIM has seen wider adoption in design and construction. The interviews validated the factors that influence the implementation of BIM and LC in PHC projects in China.

The study uses a strengths, weaknesses, opportunities and threats analysis framework to clarify the opportunities, threats, strengths and weaknesses of BIM and LC in China’s PHC and proposes strategies.

The composition and corrosion behaviors of recycled and virgin Pb anode were investigated in industrial zinc electrowinning solution with different methods. The purpose of this study is the illustration of good anticorrosion activity of virgin Pb anodes compared to recycled one in industrial operation, while the compositions of both of them are the same which obtained from quantmetry method.

Its corrosion properties and electrocatalytic activity toward oxygen evolution reaction were appraised using potentiodynamic polarization, electrochemical impedance spectroscopy, galvanostatic polarization and ionic equilibrium methods. In addition, composition of anodes investigated with X-ray photoelectron spectroscopy (XPS) method. The surface composition of samples was studied via X-ray diffractogram (XRD).

The results indicate that the anodes display different anodic behaviors during the galvanostatic polarization. Virgin Pb anode shows a “potential reduction” about 320 mV lower than recycled Pb anode after 6 h of polarization; also, the stable potential after 72 h for virgin Pb anode is 100 mV lower than recycled Pb anode. Also, The XPS results show a trace amount of Cl in recycled anodes which cause the more corrosion activity. XRD results indicate that virgin Pb anodes have been covered by more oxides than recycled anodes after 72 h of electrowinning.

The treatment of corrosion behavior by virginity has not been detected by any researchers yet. Therefore, it is imperative to study the corrosion behavior and exact composition analysis of virgin and recycled Pb anodes to comprehension of them. This paper fulfills this need.
