Published: June 2015

AbstractGibberellin (GA) regulates plant development primarily by triggering the degradation/deactivation of the DELLA proteins. However, it remains unclear whether all GA responses are regulated by DELLAs. Tomato (Solanum lycopersicum) has a single DELLA gene named PROCERA (PRO), and its recessive pro allele exhibits constitutive GA activity but retains responsiveness to external GA. In the loss-of-function mutant proΔGRAS, all examined GA developmental responses were considerably enhanced relative to pro and a defect in seed desiccation tolerance was uncovered. As pro, but not proΔGRAS, elongation was promoted by GA treatment, pro may retain residual DELLA activity. In agreement with homeostatic feedback regulation of the GA biosynthetic pathway, we found that GA20oxidase1 expression was suppressed in proΔGRAS and was not affected by exogenous GA3. In contrast, expression of GA2oxidase4 was not affected by the elevated GA signaling in proΔGRAS but was strongly induced by exogenous GA3. Since a similar response was found in Arabidopsis thaliana plants with impaired activity of all five DELLA genes, we suggest that homeostatic GA responses are regulated by both DELLA-dependent and -independent pathways. Transcriptome analysis of GA-treated proΔGRAS leaves suggests that 5% of all GA-regulated genes in tomato are DELLA independent.

Web spam detection using trust and distrust-based ant colony optimization learning
Authors: Manaskasemsak Bundit , Rungsawang Arnon 
Published: June 2015

Purpose
– This paper aims to present a machine learning approach for solving the problem of Web spam detection. Based on an adoption of the ant colony optimization (ACO), three algorithms are proposed to construct rule-based classifiers to distinguish between non-spam and spam hosts. Moreover, the paper also proposes an adaptive learning technique to enhance the spam detection performance.

Design/methodology/approach
– The Trust-ACO algorithm is designed to let an ant start from a non-spam seed, and afterwards, decide to walk through paths in the host graph. Trails (i.e. trust paths) discovered by ants are then interpreted and compiled to non-spam classification rules. Similarly, the Distrust-ACO algorithm is designed to generate spam classification ones. The last Combine-ACO algorithm aims to accumulate rules given from the former algorithms. Moreover, an adaptive learning technique is introduced to let ants walk with longer (or shorter) steps by rewarding them when they find desirable paths or penalizing them otherwise.

Findings
– Experiments are conducted on two publicly available WEBSPAM-UK2006 and WEBSPAM-UK2007 datasets. The results show that the proposed algorithms outperform well-known rule-based classification baselines. Especially, the proposed adaptive learning technique helps improving the AUC scores up to 0.899 and 0.784 on the former and the latter datasets, respectively.

Originality/value
– To the best of our knowledge, this is the first comprehensive study that adopts the ACO learning approach to solve the problem of Web spam detection. In addition, we have improved the traditional ACO by using the adaptive learning technique.
Foreign direct investment industry characteristics and spillovers
Authors: Chen Taotao , McQuaid Ronald W. , Omar Maktoba 
Published: June 2015

Purpose– The purpose of this paper is to develop a double mechanism model to separate two foreign direct investment (FDI) intra-industry spillovers mechanisms: spillovers by FDI intensity and by FDI efficiency. This paper seeks to illustrate the potential use of the double mechanism model rather than provide precise estimates of spillovers. The evidence on the links between technology and the nature, size and mechanisms of FDI spillovers effects in economically developing countries is mixed.Design/methodology/approach– A model is developed and tested, in principle. Empirical testing was conducted in two steps. In the first step, the authors examined the effect of each influencing factor to FDI spillovers separately. To complete this step, the authors divided the whole sample industry into sub-groups and tested them with the double-mechanism using ordinary least squares regression. This study applies Chinese National Bureau of Statistics manufacturing industry level data, for the years 2000, 2001 and 2002, including the food industry, beverage industry, textile industry, textiles and garments, chemicals and chemical products industry, overall manufacturing equipment, special equipment, computer and other electronic equipment manufacturing industries.Findings– The analysis suggests significant differences between types of spillovers: export orientation of domestic firms mainly influences FDI spillovers by intensity; the capability gap between local and foreign firms influences spillovers by efficiency; and the growth of local firms influences both types of spillovers. This paper develops existing models of FDI and suggests that disaggregating spillovers types may provide important theoretical and policy insights.Originality/value– This study has found, first, that compared with the classic single mechanism model, the double mechanism model is more appropriate for testing FDI intra-industry spillovers, as it is able to separate spillovers by intensity and spillovers by efficiency, which are shown as two distinct mechanisms for FDI spillovers. This allows a deeper analysis into each mechanism and the identification of relevant influencing factors.
Is China’s investment in Africa good for the Nigerian economy?
Authors: Nnanna Joseph 
Published: June 2015

Purpose
– The aim of this paper is to assess the impact of China’s trade agreement and foreign direct investment (FDI) flows to Nigeria with special reference to the manufacturing sector utilizing the following key economic performance indicators: inflation, unemployment, income and gross domestic product, to name a few. Since the turn of the millennium, China has enjoyed a substantial presence in the African continent. In fact, the country has signed bilateral agreements with Angola, South Africa and Sudan to name a few. Recently, China established its West African trade hub in Lagos, the economic capital of Nigeria, to be strategically positioned. The results of the study revealed conclusively that although China’s investments over the years have benefited the Nigerian economy and its various firms in the manufacturing sector, the agreement signed by both countries ultimately needs to be reexamined to ensure equity.

Design/methodology/approach
– To thoroughly analyze the effects of China’s investments in Nigeria, this study was carried out in two phases. The first analysis of this study is anchored on a “before/after” framework based on descriptive statistical analysis of the selected economic performance indicators chosen from selected cross-national data. Accordingly, the time frame for this study runs from 1993-2012 which roughly corresponds to the era when China commenced significant investments in Nigeria. Second, employees, policymakers and individuals in the manufacturing/textile industries were interviewed. Furthermore, participation from federal as well as local government agency staff members was solicited using the Delphi technique.

Findings
– Empirically, the results conclusively reveal China’s dominance in the manufacturing and textile sectors in Nigeria. In other words, at face value, China’s investments are ultimately good for the Nigerian economy. However, at a micro-level analysis, the researcher examined the human factor, that is, the families of former and current employees, abandoned businesses/factories and a decaying textile industry that was once vibrant.

Originality/value
– To the knowledge of the researcher, this is the first study attempting to assess the impact of the rise of China on the Nigerian economy by combining key economic performance indicator in tandem with face-to-face interviews and the Delphi technique.
“Keeping the family side ticking along”
Authors: Baker Charlotte , Ciuk Sylwia 
Published: June 2015

Purpose
– The purpose of this paper is to explore the work-family interface of two non-traditional forms of expatriation. The paper contributes to existing research by comparing and contrasting the experiences of international business travellers and rotational assignees, pointing out the similarities in their experiences but also showing considerable differences in how the work-family interface plays out in these two groups.

Design/methodology/approach
– In line with the exploratory nature of the research, the authors carried out a qualitative case study drawing on interview data with rotators and international business travellers (n=20). In order to get more in-depth insights into the experiences of these two groups of assignees, the authors also used the photo-elicitation technique, which corresponds with the recent recognition that the evolving nature of international assignments requires alternative methods of inquiry to enhance the understanding of the challenges faced by them.

Findings
– The study points to four major factors affecting the work-family interface: time spent away, unpredictability of work schedules, limited ability to exercise control over it as well as limited availability of organisational support. The findings illustrate that while these factors impact international business travellers and rotators alike, their intensity varies considerably in the experiences of these two groups.

Research limitations/implications
– The research is based on a single case study and a small sample which needs to be considered when discussing the implications of the findings. Future research can valuably extend and build on the here reported observations.

Practical implications
– A number of practical implications are discussed, notably pertaining to the ways in which organisations can mitigate the challenges encountered by international business travellers and rotators.

Originality/value
– The papers focuses on two groups of assignees that are underrepresented in the expatriate literature despite their increasing empirical significance in international business.
Burden or support? The influence of partner nationality on expatriate cross-cultural adjustment
Authors: Davies Samuel , Kraeh Albert , Froese Fabian 
Published: June 2015

Purpose– The family and specifically, the partners of expatriates are unfortunately the major cause of expatriate maladjustment. Drawing from and extending the concept of relational demography, the purpose of this paper is to examine the influence of the nationality of expatriates’ partners, conceptualized as host, home or third country nationality, on expatriates’ cross-cultural adjustment.Design/methodology/approach– Survey data from 299 expatriate academics in China, Japan and South Korea were analysed. The authors used confirmatory factor analyses to validate the scales and ANCOVA to test the hypotheses. To further understand the interactions effects the authors conducted simple slopes analysis.Findings– Results show that differences in expatriate academics’ cross-cultural adjustment are notper sebased on the different nationality of their partners, but are mainly due to an interaction effect of partner nationality and length of stay in host country. Expatriates with host country national partners perceived the highest increase in cross-cultural adjustment over time, followed by those with third country national partners, whereas those with home country partners did not experience any increase in cross-cultural adjustment.Research limitations/implications– The study was based on a cross-sectional survey of expatriate academics in Asia. Thus, longitudinal, multisource data from various contexts would increase validity and generalizability of findings. Despite these limitations, the study provided new and intriguing findings. The theory and empirical evidence underscore the importance of expatriate partner nationality and thereby, relational demography between expatriate partners and expatriates.Practical implications– The research aims to emphasize the important role that expatriate partners can play concerning the success of expatriate cross-cultural adjustment. Greater attention should be paid to the adjustment processes of expatriates and their partners to facilitate expatriate cross-cultural adjustment.Originality/value– The authors are among the first to study the influence of nationality, conceptualized as host, home country or third country nationality, of expatriates’ partners on expatriates’ cross-cultural adjustment by applying the concept of relational demography. Moreover, the authors look at the role that time in the host country has on the partner’s influence on expatriate adjustment.
“Let me back into the world” – compassionate care in practice: a carer and patient’s view
Authors: Minogue Virginia 
Published: June 2015

Purpose– “Let me back into the world” was the heart rending response by an older relative to a question about his wellbeing following a difficult period of illness and hospitalisation. As his main carer, the author of the paper was struck, when visiting the hospital, by a small poster, on a notice board near to the entrance to the hospital ward, outlining the staff’s commitment to Compassion in Practice. Compassion in Practice was enshrined in the Compassion in Practice vision and strategy (Department of Health, NHS Commissioning Board, 2012) for building a culture of compassionate care across health and social care. A key element of the strategy was to make the values of care, compassion, courage, communication, competence and commitment, real and visible to patients and the public. The purpose of this paper is to seek to compare the values being stated with the care experience.Design/methodology/approach– This paper records a personal perspective from a patient and their family carers of compassionate care in practice. This experience is one case study and does not seek to represent the experience of other patients and their families.Findings– This highlights the importance of communication and demonstrates that care and compassion are human emotions and values that have to be lived in practice and are part of the interaction between patient, clinician and family. Simply believing in those core nursing values does not make them real for the patient in practice.Originality/value– Both patient and the family carers had extensive experience of working in health and social care including the NHS. This account demonstrates the challenges of turning strategy into actions that can ultimately improve the patient experience of care.
Bathing in residential care: understanding the experiences of residents and their care providers
Authors: Holroyd Ann , Holroyd Heather 
Published: June 2015

Purpose
– The purpose of this paper is to understand how changes in an older adult’s physical capacity alter their bathing preferences, how the care environment incorporates residents’ values and beliefs around bathing to fulfil these changing care needs, and how institutional factors, such as staff scheduling and communication processes, influence Resident Care Aides’ (RCAs) bathing practices.

Design/methodology/approach
– A multiple methods approach involving surveys and interviews with residents and RCAs in a Canadian residential care facility. This paper draws mostly from the semi-structured, qualitative interviews with older adult residents (n=9; Mini Mental Status Exam (MMSE) scores
>
15) and RCAs (n=10) on two nursing units offering different bathing options.

Findings
– Decreasing energy levels and physical decline were commonly cited reasons for residents’ changing bathing preferences. Residents were overall very appreciative of the bathing care they received in residential care, and identified the weekly tub bath as an anticipated encounter where they experienced a valued social interaction with their assigned RCA. While identifying bathing as an occasionally stressful aspect of their work, RCAs also described the bathing experience as an intimate bonding activity. The study identified bathing as an important activity in residential care.

Originality/value
– Previous studies have focused on moderate to severely cognitively impaired older adults’ and their demonstration of agitated behaviours during bathing. Most participants in this study had only minor cognitive impairment, as measured by MMSE scores (average score=20.6); therefore, this study provides insight into the experiences and needs of older adults whose perspective is not generally reflected in the literature.
Access to long-term care: perceptions and experiences of older Dutch people
Authors: Schipper Lisette , Luijkx Katrien G. , Meijboom Bert R. , Schalk René , Schols Jos M.G.A. 
Published: June 2015

Purpose
– Despite the current focus on demand-based care, little is known about what clients consider important when they have a request for formal long-term care services. The paper aims to discuss this issue.

Design/methodology/approach
– Questions about the access process to care services were added to the “Senior Barometer”, a Dutch web-based questionnaire that assesses the opinion of older people about different aspects in life. The questionnaire surveyed both people who already requested care services (“users”), and people that did not (“future clients”).

Findings
– The results show a significant difference in what people expect to be the first step from what users actually did, when requesting formal care services. In addition, there was a significant difference on how “users” and “future clients” rated several access service aspects.

Research limitations/implications
– The results give valuable information on how both “users” and “future clients” value the access process. The findings also provide valuable input for organizations providing long-term care for older clients about the important issues that have to be considered when organizing the access process.

Originality/value
– This study shows what older people in the Netherlands find important during the access process to care and this has not been explored before. The difference between what “users” and “future clients” find of importance in the care access process suggests that it is difficult for people to foresee what will be important once the need for care arrives, or where they will turn to with a request for care services.
Restaurant social media usage in China
Authors: Ghiselli Richard , Ma Jing 
Published: June 2015

Purpose
– The purpose of this paper is to examine the use of social media by restaurants in China and the extent to which consumers are using it to obtain information about dining options.

Design/methodology/approach
– A questionnaire for consumers was developed and social media usage data were collected from restaurants; the results were compared to determine whether there is a difference between practices and preferences.

Findings
– Based on the results of this paper, restaurants may want to consider committing resources and efforts to improve their presence on Dianping, Baidu and Meituan, and to utilize WeChat. Also, they may want to send non-personalized updates, especially coupons, discounts and information about special events, through the above-mentioned channels two to three times a month. Additionally, restaurants may want to improve engagement with frequent users so that they will recommend to others. Finally, restaurants may want to evaluate and invest in online ordering and payment systems if they haven’t done so already.

Research limitations/implications
– Strategic choices should be based on understanding of consumers. Unless the gaps between practices and preferences are identified and understood, restaurant companies may not be able to use social media effectively and efficiently.

Originality/value
– China’s social media market – the largest in the world – differs considerably from other countries; it presents unique opportunities and challenges. Social media is always a function of the technology, culture and government of a particular country or context; for this reason, it is very important to study social media in its “context”. While the need is pressing, there are limited studies on restaurant consumer preferences in a computer-mediated environment, not to mention in the Chinese context. This study examined consumer preferences and potential gaps between preferences and practices in the Chinese context; the results will help to direct restaurants in China to make better use of social media.
Trends affecting social media: implications for practitioners and researchers
Authors: Bowen John 
Published: June 2015

Purpose
– This paper aims to review relevant literature to identify trends affecting social media to help managers and researchers better understand social media; this paper also provides the implications of these trends for mangers and researchers. Social media is viewed as a credible source of information from consumers who have experienced travel products. The user-generated content these consumers post on social media Web sites influences those who read their posts or view aggregate ratings of multiple reviews about a product. It can move the reader to either purchase or not purchase the products. Social media is an important source of consumer information and can create new customers.

Design/methodology/approach
– The paper reviewed both academic and trade literature to provide an overview of social trends that are relevant to practitioners.

Findings
– The author identified four trends: millennials replacing baby boomers as the major business travel segment, increased use of mobile devices, dynamic pricing and marketing dollars shifting to social media. The implications of each of the trends are discussed. The findings provided valuable insights for practitioners and researchers.

Originality/value
– Social media is emerging as an important marketing tool for the travel industry. It is transforming the way companies allocate their marketing budget. The identification of trends that are affecting social media and will continue to affect social media in the future will provide immediate benefits to practitioners and researchers with a stream of research ideas.
