This paper aims to use the concept of machine learning to enable people and machines to interact more certainly to extend and expand human expertise and cognition.

Intelligent code reuse recommendations based on code big data analysis, mining and learning can effectively improve the efficiency and quality of software reuse, including common code units in a specific field and common code units that are not related to the field.

Focusing on the topic of context-based intelligent code reuse recommendation, this paper expounds the research work in two aspects mainly in practical applications of smart decision support and cognitive adaptive systems: code reuse recommendation based on template mining and code reuse recommendation based on deep learning.

On this basis, the future development direction of intelligent code reuse recommendation based on context has prospected.

The purpose of this paper is to examine whether analyst recommendations are influenced by the strength of corporate governance in emerging markets.

It is expected that analysts take into consideration the corporate governance mechanisms when they set their recommendations because better‐governed companies are associated with less risk from management and have value improvement potentials. This hypothesis is tested with a sample of 805 firms in 26 countries from emerging markets. Corporate governance effectiveness is measured by the ratings compiled by Credit Lyonnais Securities Asia, which are based on a series of corporate governance characteristics.

Results show that analysts tend to issue favorable recommendations for firms with better corporate governance mechanisms. Furthermore, this evidence is concentrated in countries with a code law origin where investor protection is relatively weak.

This paper has important implications for financial analysts and investors by offering insights into how analysts help the market efficiently incorporate the quality of corporate governance in the code law countries of emerging markets. This paper is also of interest to companies by highlighting the significance of establishing good corporate governance mechanisms.

Examining the association between analyst recommendations and the strength of corporate governance adds to the research on the association between corporate governance and analyst activity and therefore highlight the role analysts play in the valuation of corporate governance.

The paper seeks to analyze to what extent the contents of corporate governance codes of countries in the European Union are driven by external (internationally accepted corporate governance best practices) or domestic (institutions, culture, etc.) forces.

The paper compares the contents of codes with the priorities set by the European Commission with respect to modernising company law and enhancing corporate governance in the European Union.

The analysis shows that the majority of the codes of the European Union countries are not in full accordance with the priorities of the European Commission. This may reflect that codes are driven by both external and domestic forces. Whether there is a difference between Western European and Central and Eastern European countries in this respect is also investigated, but no difference, at least at the aggregate level of the codes of both groups of countries has been found.

The analysis excludes five (prospective) European Union members. The analysis does not provide a comprehensive overview of domestic determinants of why codes of individual countries diverge from the European Union communication. Future research should systematically explore whether and to what extent domestic forces are indeed determining the contents of codes and, if so, which country‐specific forces have an impact on establishing code contents.

This paper is the first comprehensive attempt to analyse the contents of corporate governance codes. Such an analysis is important to understand the underlying forces that shape the diffusion of codes and their contents.

Concern over the standards of corporate governance in the UK has led to the publication of three committee reports: Cadbury, Greenbury and, most recently, Hampel. Following the publication of the Hampel Report, the Hampel Committee has produced a document providing a set of principles and codes to embrace the Cadbury, Greenbury and Hampel recommendations — the Combined Code (June 1998). The purpose of this paper is to review the recommendations of the Cadbury, Greenbury and Hampel reports and to consider whether the recommendations of the Combined Code represent a significant shift in emphasis from the accountability aspects of corporate governance to consideration of the need for governance systems to provide structures and incentives to allow business enterprise to flourish.

A recommendation algorithm is typically applied to speculate on users’ preferences based on their behavioral characteristics. The purpose of this paper is to provide a systematic review of recommendation systems by collecting related journal articles from the last five years (i.e. from 2014 to 2018). This paper aims to study the correlations between recommendation technologies and e-learning systems.

The paper reviews the relevant articles using five assessment aspects. A coding scheme was put forward that includes the following: the metrics for the e-learning system, the evaluation metrics for the recommendation algorithms, the recommendation filtering technology, the phases of the recommendation process and the learning outcomes of the system.

The research indicates that most e-learning systems will adopt the adaptive mechanism as a primary metric, and accuracy is a vital evaluation indicator for recommendation algorithms. In existing e-learning recommender systems, the most common recommendation filtering technology is hybrid filtering. The information collection phase is an important process recognized by most studies. Finally, the learning outcomes of the recommender system can be achieved through two key indicators: affections and correlations.

The recommendation technology works effectively in closing the gap between the information producer and the information consumer. This technology could help learners find the information they are interested in as well as send them a valuable message. The opportunities and challenges of the current study are discussed; the results of this study could provide a guideline for future research.

This study aims to investigate the relationship between national culture and best practices as recommended in country-level corporate governance codes.

Measures for four corporate governance variables – board independence, gender composition, board leadership and meeting frequency – were collected from corporate governance codes for 55 countries. Scores from Hofstede’s cultural dimensions – power distance, individualism vs collectivism, masculinity vs femininity and uncertainty avoidance – were gathered for these same countries. Average scores on the cultural dimensions were compared for groups of countries based on each of the corporate governance variables.

Data analyses reveal significant relationships between Hofstede’s cultural dimensions and the four characteristics of corporate governance examined in this study. Results highlight the importance of understanding cultural influences on board characteristics for companies considering international expansions or partnerships.

While prior studies have focused on the influence of national culture at the company level, this study examines the relationship at the regulatory level through review of country-level corporate governance codes.

This paper aims to empirically investigate the relationship between the level of compliance with the German Corporate Governance Code’s (GCGC) recommendations and the implied cost of equity capital (ICC). German listed companies are required by law to annually disclose their compliance with the recommendations of the GCGC. Whether the GCGC achieves its aim to promote the trust of stakeholders in the management and supervision is still an open question.

ICC is regressed on a score that captures compliance with the GCGC and several control variables. The dataset covers the period of 2003-2012 with declarations of compliance from 447 companies. ICC is chosen as an outcome variable, as it captures general investment risk as well as risk arising from asymmetric information and mistrust of investors in management.

The results of the empirical analysis demonstrate that a higher level of GCGC compliance is associated with lower ICC.

It is expected that the results of this study will strengthen acceptance of the GCGC and empirically support the work of the government commission that is responsible for it. It has not been analyzed yet whether the firms cite good reasons why they do not adhere to certain items.

This empirical analysis is the first to provide statistically reliable evidence on how compliance with the GCGC affects ICC and whether the work of the government commission reflects good corporate governance as perceived by capital markets.

This paper aims to examine the two different approaches adopted in the UK to regulate directors’ remuneration. The paper also aims to explore the two approaches to understand which one better regulates directors’ pay and why. It provides an account of the two approaches’ evolution, effectiveness and challenges towards the regulation of directors’ remuneration. The paper will also make some recommendations on both approaches and the way forward to better regulate directors’ remuneration.

The paper reviews various corporate governance codes, its recommendations on directors’ remuneration, its effectiveness and the challenges it face in regulating directors’ remuneration. The paper also reviews provisions of the Companies Act 2006 on directors’ remuneration, its effectiveness and challenges faced.

The paper finds that corporate governance adopts a better approach to regulating directors’ pay than the Companies Act 2006 because it targets the pay setting process. However, the existence of grey areas and lack of enforcement procedure poses a challenge on its effectiveness. The Companies Act 2006 is unable to regulate directors’ pay adequately because it adopts a corrective approach and it considers directors’ remuneration as a management responsibility.

The paper offers an up-to-date assessment of the two approaches to regulating directors’ pay in the UK. It highlights the challenges faced by both approaches and which approach could regulate directors pay better and its challenges. The paper further makes recommendations on how the regulation of directors’ remuneration can be effective in the UK.

This paper provides evidence regarding the efficacy of the “comply or explain” approach in Greece and has three objectives: to improve our knowledge of the concept of this accountability mechanism, to elevate auditors’ potential role in the control of corporate governance (CG) statements and to contribute to the discussion about the reform of this principle; a prolonged dialogue that has been started by European Commission in the light of the recent financial crisis.

The approach taken is a content analysis of CG statements and Web sites of a non-probability sample of 144 Greek listed companies on the Athens Stock Exchange for the year 2011. Particularly, 52 variables were evaluated from an audit compliance perspective using a coding scheme. From this procedure, the level of compliance with Hellenic Federation of Enterprises (SEV) code, as well as the content of the explanations provided for non-compliance, were rated.

The results show that although the degree of compliance is low (the average governance rating is 35.27 per cent), the evaluation of explanations of non-compliance is even lower (from the 64.73 per cent of the non-compliance, the 40.95 per cent provides no explanation at all).

The research limitations are associated with the content analysis methodology, as well as the reliability of CG statements.

This study indicates that companies on the one hand tend to avoid the compliance with these recommendation practices, raising questions regarding the effectiveness of the SEV code; while on the other, they are not in line with the spirit of the CG code, as they do not provide adequate explanations. These results assist practitioners and/or policy-makers in perceiving the efficacy of the “comply or explain” approach.

While there is a great body of research that has looked into the compliance with best practices, this study is different because it is the first one that rates not only the degree of the compliance with the code’s practices but also the content of the explanations provided for non-compliance. This is particularly interesting because it adds to the body of research by providing a new approach in measuring the quality of the “comply or explain” principle in-depth.

The audit committee is one of the most prominent board sub‐committees, having a potentially important role to play in ensuring sound corporate governance. This paper aims to examine and discuss the behaviour of companies following revisions to the UK's Revised Code.

A variety of annual report data from a sample of 50 UK companies, stratified according to size, is collected and analysed.

General compliance with many provisions of the Revised Code was found. All but one company had an audit committee comprising solely non‐executive directors. However, in about a quarter of cases the chairman was a member, and in some cases directors were not “independent” according to the Code's definition. Nevertheless, many companies exceeded the minimum stipulated requirements, for example the number of non‐executive directors on the audit committee or the number of meetings held. Some companies, though, did not follow recommended practice, particularly regarding the disclosure of information, and some explanations for non‐compliance were weak.

Compliance with disclosure demands regarding audit committees could be improved, as could the quality of explanations when the recommendations of the Code are not followed. It would be sensible for regulators to monitor this, provide more detailed guidance and highlight examples of good practice. Given the resistance of many companies to corporate governance regulation and accusations of “box ticking”, future research should probe why many companies do more than is required or recommended. The research should be repeated when further revisions to the Code are made in respect of audit committees, and practice in countries other than the UK should be researched to provide comparative insights.

This paper provides useful information on the behaviour of companies following revisions to the UK's Revised Code.
