The purpose of this study is to establish a novel airfoil icing prediction model using deep learning with geometrical constraints, called geometrical constraints enhancement neural networks, to improve the prediction accuracy compared to the non-geometrical constraints model.

The model is developed with flight velocity, ambient temperature, liquid water content, median volumetric diameter and icing time taken as inputs and icing thickness given as outputs. To enhance the icing prediction accuracy, the model involves geometrical constraints into the loss function. Then the model is trained according to icing samples of 2D NACA0012 airfoil acquired by numerical simulation.

The results show that the involvement of geometrical constraints effectively enhances the prediction accuracy of ice shape, by weakening the appearance of fluctuation features. After training, the airfoil icing prediction model can be used for quickly predicting airfoil icing.

This work involves geometrical constraints in airfoil icing prediction model. The proposed model has reasonable capability in the fast assessment of aircraft icing.

Social network sites are becoming more visual-centric. The purpose of this paper is to examine the effectiveness of visual social network sites as a marketing platform.

This paper comprises two experiments. The first experiment sought to examine the effect of social influence; while the second experiment examined the effect of image quality on the perception of quality and purchase intention.

The first experiment showed that social influence did not affect perceived quality or purchase intention. In the second experiment, a one-way between-groups multivariate analysis of covariance (MANCOVA) adjusting for sport involvement showed a statistically significant difference between the two groups. Respondents in the experimental group reported higher levels of perceived quality (adjusted M=3.68) and purchase intention (adjusted M=3.23) when compared to the control group’s perceived quality (adjusted M=3.12) and purchase intention (adjusted M=2.17).

One of the limitations of this study is that it only examined the effects through a single social network site, i.e. Instagram. As there are other visual-centric social network sites, such as Tumblr and Pinterest, which operate slightly different from Instagram, it remains to be established how such effects vary across these social network sites.

The results suggest that social influence on Instagram is limited and marketers should invest in images of high quality when marketing on visual social network sites.

While there are many studies examining the effectiveness of marketing on social network sites, these studies have primarily focussed on earlier social network sites, such as Facebook. Newer social network sites that are more visual-centric, such as Instagram, are different from earlier social network sites and studied to a lesser extent. This study adds insights on the marketing effectiveness of visual-centric social network sites and deepens the understanding on marketing in general on social media.

As sports sponsorship is a common marketing tool among commercial organisations, there had been a large number of studies examining the effectiveness of sponsorship. The aim of this study is to examine whether colour affects sponsorship effectiveness on printed advertisements of sports events. This is an area that has received less research interest.

In total, 85 participants were randomly assigned to a control group and three experimental groups. In each of the groups, the participants viewed an advertisement of a sports event on a computer linked to an eye tracker. In the control group, the logos of sponsors were in their original colours. In each of the three experimental groups, the logos were manipulated and featured greyscale, blue or red backgrounds.

The study found that sponsor recall and recognition rates were highest for the control group. Visual attention was also the highest in the control group.

The findings suggest that manipulating colours of the sponsors' logos can negatively affect attention and sponsorship effectiveness.

While there exist studies that focus on the effects of colour in sponsorship, they are typically conducted with regard to physically attending the event itself. However, sponsorship involves other marketing collaterals such as printed advertisements on the event. In such mediums, colour contrast is also important in print advertisements as it affects readability and legibility. As such, the examination of effect of colour on such marketing collaterals provides additional empirical support to the phenomenon.

The purpose of this paper is to examine whether different corporate social responsibility (CSR) dimensions, namely, workplace economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility and environmental responsibility, have different influence on job pursuit intention among undergraduate students in Malaysia.

The target respondents are undergraduate business students from five leading private universities in Malaysia. Primary data were collected through survey questionnaires via face-to-face method. Five-point Likert scale was used to assess the variables and to measure the items. Collected data were tested through SAS software and analysed with descriptive and inferential analyses.

Four out of the five CSR dimensions significantly influence job pursuit intention with ethical responsibility being the exception.

This study proved that the adoption of CSR in an organisation will become a competitive advantage to attract new talents. Also, this is an improved research model by adopting multi-dimensional perspectives of CSR.

This proposed framework with a combination of five CSR dimensions (workplace economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility and environmental responsibility) is useful to future researchers as it enables them to have a broader view on CSR and its effect on job pursuit intention.

In 2020, the EtonHouse International Education Group (EtonHouse) celebrated its 25th anniversary. Under the leadership of Ng Gim Choo, founder and managing director, EtonHouse has become a renowned education provider noted for its well-designed inquiry-based curriculum. Since its initial expansion in Singapore, the institution has spread across the world. Throughout its history, EtonHouse has faced many crises. However, employing paradoxical leadership, Ng Gim Choo has managed to accommodate conflicting demands and guide EtonHouse away from adversity. In early 2020, the coronavirus pandemic (COVID-19) posed an unprecedented challenge to EtonHouse. In addition to developing business strategies in response to COVID-19, Ng Gim Choo has been considering whether the time is ripe to hand over the reins to Ng Yi Xian, her son and EtonHouse successor.

By presenting the dilemma of business succession in crises, the case study facilitates in-depth discussion of several issues related to family business succession, succession planning and crisis management. Students will be able to explore the following issues: 1. The concept and implications of paradoxical leadership and its application in business decisions. 2. How to lead during crises. 3. The tension between succession plans and crisis management. 4. The characteristics and implications of woman entrepreneurship.

The purpose of this paper is to examine the indigenous Chinese concept of suzhi (素质) with the aim of furthering the development of Chinese human resource management (HRM) research and practice.

An extensive review of the literature on suzhi, published in the West, as well as in China, is the basis for proffering an organizational-level conceptualization of suzhi in the Chinese context.

Instead of understanding it as a free-floating signifier, we argue that suzhi can be considered as a criterion-based framework for HRM research and practice. Suzhi research is classified into two major sources – indigenous Chinese and indigenized Western constructs. We further make a distinction between intrinsic and extrinsic suzhi, and analyze a popular set of suzhi criteria, considering de (morality) and cai (talent), while focusing on de in HRM selection (德才兼备, 以德为先). As multilevel and multidimensional framework, suzhi criteria may form different gestalts in different organizations and industries.

From a social cultural and historical perspective, HRM research that incorporates a combination of indigenous and indigenized suzhi characteristics may receive better acceptance by individuals, organizations and the society in the Chinese context. Accordingly, the reconstruction of suzhi into manageable and measurable dimensions can be undertaken for more effective HRM practice in the Chinese context.

The HRM literature is advanced by linking the indigenous suzhi discourse to Chinese indigenous HRM research and practice.

Recognising interest in the nascent “rise of China”, the purpose of this paper is to engage with the normative social science approach to comparative management, positing that it is inadequate for an enlightened view of the Chinese subject.

This paper presents a critical appraisal of extant literature, specifically Redding's The Spirit of Chinese Capitalism, by drawing resources from Fabian's epistemological critique of anthropology and Levinas' ethics to replace ontology as first philosophy, and by reference to historical studies on China's economic culture and its language.

Attention is drawn to how Redding's research subject is made an object of knowledge. In the objectification process, the subject's continuity is interrupted, its voice deprived, and its capacity for dialogue denied. This is evident in Redding's framework for analysis. Indeed, his Weberian social science template manifests a certain “imperialism of the same” and is symptomatic of much in comparative management regarding non‐western subjects. After critique, this essay then explores a supplement to Redding.

The paper proposes three principles for finding one's way out of objectification: ethics before “knowledge”, justice before “power”, and dialogue before “vision”.

The paper contributes to discourse on how comparative management must transcend its imperial social science legacy before it can find a just footing, and be born again.

Forests should be thought of not merely as “timber”, but also as treasuries of plants and animals as well as “green reservoirs”. The preservation and management of montane forests are therefore of importance. Different ways should be adopted according to the corresponding conditions of four montane forest regions of China. Afforestation in the humid eastern plains and southern rolling hills should be paid great attention, because these areas have much more rainfall, deep and fertile soil and sufficient atmospheric heat. Protection forests planted on farmlands and along the southeastern seaboard not only raise the output of crops, but also provide timber, fuel and forage. It is necessary to strengthen the rewarding utilisation system of forest resources. The current irrational remuneration of afforestation workers and forest engineering workers doing similar jobs but for different wages must be changed.

Based on government data from 1993 to 2008, this chapter aims to compute and analyze the trends of inequity in interprovincial and regional per-student spending in China's compulsory education, and to ascertain the potential impact of changes in education financing policies. Appropriate inequity measures (Gini and Theil index and Gini decomposition, among others) are employed to provide a systematic picture of the trends. Main findings include: (1) all inequity measures show large and overall increased disparities among provinces and among regions, between 1993 and 2008. (2) However, a slight drop of spending inequity is observed at the primary education level around 2002 and a larger reduction in 2005 and on. There are more turning points in the trend of lower-secondary per-student spending among provinces. These patterns are consistent across different inequity measures and spending indicators (per-student total spending, per-student recurrent spending, and per-student nonpersonnel spending). (3) The trend toward more balanced resource allocation around 2002 and 2005 could be the impact from the Reform of Tax and Administrative Charges and the New Mechanism for Financing Rural Compulsory Education. An increased share of budgetary expenditure in determining total spending suggests that equalizing financing policies have the potential to induce a significant reduction in spending inequity. These findings may help policy makers to better understand and alter the extent of spending inequity in compulsory education. This is an original empirical study that systematically derives the spending inequity trends over a long period in China's compulsory education.
