The machination of foreign direct investment flow to emerging markets – a focus on Africa
Authors: Aregbeshola Rafiu Adewale 
Published: July 2018

Purpose
The deterministic role of various macroeconomic fundamentals on the attractiveness of countries to inflow of FDI is well documented in literature. The role of market size, infrastructural development, inflation and exchange rates differential have been supported as determinants of FDI direction. However, no documented study has benefited from diverse measures of institutional adequacy as presented in this study. The paper aims to discuss these issues.

Design/methodology/approach
The paper adopts various econometric approaches that include descriptive statistics, fixed effects models, LM test of independence, feasible generalised least squares regression and SUR estimations.

Findings
This study unveils the specific impacts and explanatory power of each of the variables along country lines, and the author compares the results of some emerging markets in Asia, Eastern Europe, and South America to some selected countries in Africa. Using data set from various sources over a period of 44 years in a seemingly unrelated regression environment, this study suggests that poor technological capability, inadequate political system, weak productivity gains are major deterrents to the attractiveness of African countries to inflow of FDI.

Research limitations/implications
The major limitation of this study revolves around availability of usable data, which compels the researcher to limit the focus and the span of time series.

Practical implications
The study suggests the need to improve institutional quality in emerging economies, especially countries in Africa in order to enhance their attractiveness to FDI inflow. More importantly, the study found that low capital productivity gains hinder the attractiveness of African emerging markets to FDI inflow.

Social implications
To alleviate poverty, attraction of FDI is considered important, and the improvement of institutional functionality in that regard is found to be important. The need to augment technological improvement is considered very important and critical.

Originality/value
This serves to confirm that the article entitled “The Machination of Foreign Direct Investment Flow to Emerging Markets – A focus on Africa” is my own original work, envisaged to contribute to the debate about the role of macroeconomic fundamentals, especially capital productivity gains as determinants of a country’s attractiveness to inflow of foreign capital in academic literature.

Marcellus Shale play and the cointegration of natural gas markets in the Northeast
Authors: Arano Kathleen , Velikova Marieta , Gazal Kathryn 
Published: July 2018

PurposeThe development of the Marcellus Shale Play has altered the geography of production in the USA, particularly in the Northeast natural gas market. The purpose of this paper is to examine its impact on an already integrated industry.Design/methodology/approachThe authors utilize the methodology of co-integration and focus on the geographic reach of the Marcellus region to examine movements of prices across the upstream, midstream and downstream segments of the industry.FindingsThe results of this paper indicate that prices across segments remain strongly co-integrated with the boom in production. The short-run dynamics, however, reveal a slower adjustment to the long-run equilibrium following the boom, particularly for wellhead to city-gate and wellhead to residential prices.Originality/valueThe growth in delivery infrastructure has not kept up with the boom in production creating bottlenecks. The supply shock brought about by the boom in production has not altered previously established co-integrating relationships but has altered the speeds of adjustment towards the long-run equilibrium.
Performance comparison of hole-entry and slot entry hybrid journal bearings considering combined influence of thermal effects and micropolar lubricant
Authors: Khatak Pankaj , Garg H.C. 
Published: July 2018

Purpose
Hybrid journal bearing have long been used in machines requiring large load and high speed capacity operating under wide range of temperatures. Different compensating devices are used in for efficient operation of bearings. This paper aims to help in selection of optimum compensating device by evaluating the comparative performance of constant flow valve, capillary compensated and slot entry hybrid journal bearing under the combined influence of thermal effects and micropolar nature of lubricant.

Design/methodology/approach
The variation in micropolar parameters and viscosity change due to temperature increase of lubricant are considered in present study. Finite element method is used for combined iterative solution of micropolar Reynolds, energy and conduction equations. Micropolar lubricant is assumed to be governed by two parameters, coupling number and characteristic length. The results in the study are presented for symmetric and asymmetric configurations of hole entry and slot entry non-recessed hybrid journal bearings

Findings
The results indicate that constant flow valve compensated hole entry hybrid journal bearing is the highest performing bearing for the given range of micropolar parameters of lubricant in terms of maximum fluid pressure and dynamic coefficients.

Originality/value
The performance variations of various configurations of hybrid journal bearing are presented in a single paper. The reader can get overview of combined effects of micropolar parameters and viscosity decrease due to temperature increase of the lubricant.
Leadership, trust in management and acceptance of change in Hong Kong’s Civil Service Bureau
Authors: Cai Wen Juan , Loon Mark , Wong Peter Hoi Kin 
Published: July 2018

Purpose
The purpose of this paper is to examine whether trust in management mediates the relationships between two types of leadership (transactional and transformational) and acceptance of change in the Hong Kong public sector.

Design/methodology/approach
Data from 68 civil servants in the Hong Kong SAR Government were used in the partial least squares analysis.

Findings
The findings from civil servants show that although trust in management mediates the relationship between both types of leadership and acceptance of change, transformational leadership is more effective in increasing both trust and acceptance of change.

Research limitations/implications
The strong support for the mediation hypotheses highlights the need for leaders to be trusted by their followers if followers are to accept and support the change process. Trust in management is what ultimately reduces resistance to change.

Practical implications
The findings from this study have demonstrated that one strategy available to leaders in the Hong Kong public sector is to concentrate on developing perceptions of trustworthiness by utilising both transactional leadership and transformational leadership but especially transformational leadership.

Originality/value
This paper provides a unique and nuanced view of leadership and trust, and their effect on the acceptance of change in Hong Kong’s civil service bureau that operates in a turbulent environment. Public sector organisations in Hong Kong are unique in that they contend with pressures from Hong Kong nationals and also with pressures from the Government of Mainland China.
Effectuation, opportunity shaping and innovation strategy in high-tech new ventures
Authors: Guo Runping 
Published: July 2018

PurposeInnovation strategy is critical for firms to achieve success in the market. However, relatively little is known about what factors promote the development of innovation strategy in high-tech new ventures. The purpose of this paper is to address this gap by developing and examining the theoretical model that links effectuation to innovation strategy through opportunity shaping in high-tech new ventures.Design/methodology/approachThe proposed theoretical model is developed by integrating the effectuation theory, innovation strategy literature and opportunity literature. Empirical data were collected from 212 entrepreneurs and top executives in Chinese high-tech new ventures through a survey. Baron and Kenny’s (1986) mediation and moderation model assessment procedures are used to analyze the data.FindingsThe empirical results indicate that effectuation has a positive effect on innovation strategy and opportunity shaping. Opportunity shaping has a positive effect on innovation strategy, and its effect is positively moderated by competitive intensity. The author also finds that opportunity shaping plays a fully mediating role in the relationship between effectuation and innovation strategy.Originality/valueThese findings enrich innovation strategy research and advance the effectuation theory by providing empirical evidence of the impact of effectuation on innovation strategy in high-tech new ventures. The findings also contribute to a growing stream of research on opportunity and integrating opportunity shaping into a more complete framework of innovation. Moreover, this research provides deeper insight into the missing links between effectuation and innovation strategy in high-tech new ventures by uncovering the mediating role of opportunity shaping.
How does greenwashing affect green branding equity and purchase intention? An empirical research
Authors: Akturan Ulun 
Published: July 2018

Purpose
The purpose of this paper is to explore the relationship among greenwashing, green brand equity, brand credibility, green brand associations and purchase intention.

Design/methodology/approach
As an object to study, two brands were chosen: a high-involved brand and a low-involved brand. Data were collected from 500 consumers by survey method, and structural equation modeling was run to test the research hypotheses.

Findings
As a result, it was found that green brand associations and brand credibility positively affect green brand equity, and green brand equity has a positive and strong impact on purchase intention of consumers. In addition to that greenwashing negatively affects green brand associations and brand credibility, and therefore, indirectly influence green brand equity and purchase intention.

Research limitations/implications
Previous studies conceptualize greenwashing and examine its effects on company performance and skepticism. This study is a first attempt to explore the effects of greenwashing on green branding strategies.

Practical implications
Managers should be aware of that greenwashing not only negatively affects purchase intention but also generates negative outcomes for the relationship with the brands.

Originality/value
There is no other study, at least to the author’s knowledge, testing the effects of greenwashing on green brand perceptions and green purchase intention.

Published: July 2018

AbstractThe hemodynamic effects of hemodialysis (HD) and peritoneal dialysis (PD) on end‐stage renal disease (ESRD) patients differ. The influence of dialysis modalities on the cardiovascular system has not been well investigated. We aimed to evaluate the association between dialysis modalities and risk of coronary artery disease (CAD) by using the claim data of Taiwan's Longitudinal Health Insurance Database. This study followed up a cohort of 1624 new onset ESRD patients (≥18 years old), who had started renal replacement therapy during 2000 to 2010; and was followed until 2012. After adjusting for potential confounders, patients who underwent HD had significantly higher risks of incidence of CAD, in comparison with patients who underwent PD (adjusted hazard ratio = 1.47; 95% confidence interval = 1.01–2.11). An increased risk of incident CAD was distinguished in patients receiving HD, compared with those on PD. Further studies are warranted to explore the underlying mechanism and improve dialysis outcomes.

AbstractEicosapentaenoic acid (EPA)/arachidonic acid (AA) ratio showed inverse associations with cardiovascular disease (CVD) in general population. However, this has not been examined enough in dialysis patients. We cross‐sectionally investigated the relationship between EPA/AA ratio and prevalence of CVD in 321 chronic hemodialysis patients (64 ± 11 years old; 110 women; dialysis vintage 10 ± 8 years) in an urban area of Tokyo. CVD was defined as a composite of ischemic heart disease, ischemic stroke and hemorrhagic stroke. The frequency of dietary fish intake was also examined. Logistic regression was used to quantify the association of EPA/AA ratio with CVD. EPA/AA ratio was 0.31 ± 0.19 and 154 patients (48%) consumed fish once or less weekly. One hundred and thirty patients (41%) had CVD, including 65 with ischemic heart disease, 70 with ischemic stroke, and 20 with hemorrhagic stroke. Age (odds ratio [OR], 1.04; P = 0.01), hypertension (OR, 2.25; P = 0.002), and dialysis vintage (OR, 1.04; P = 0.02) were associated with CVD; however, EPA/AA was not after adjustment for other risk factors. A similar relationship was observed between fish intake and CVD prevalence. We did not find any significant association between EPA/AA ratio and prevalence of CVD, although traditional risk factors such as age, hypertension and dialysis vintage were associated with CVD. These results might have been influenced by the fact that only a small proportion of our patients showed a high EPA/AA ratio.
Correlation between progression‐free survival, tumor burden, and circulating tumor DNA in the initial diagnosis of advanced‐stage EGFR‐mutated non‐small cell lung cancer
Authors: Lee Yunkyoung , Park Sojung , Kim Woo Sung , Lee Jae Cheol , Jang Se Jin , Choi Jene , Choi Chang‐Min 
Published: July 2018

BackgroundThis study was conducted to identify whether the presence of circulating tumor DNA (ctDNA) in plasma before treatment with EGFR‐tyrosine kinase inhibitors (TKIs) is associated with clinical outcomes.MethodsFifty‐seven pairs of tissues and plasma samples were obtained from patients with NSCLC adenocarcinoma harboring activating EGFR mutations before the administration of EGFR‐TKI treatment. ctDNA mutation was identified using the PANAMutyper EGFR mutation kit. Both qualitative and quantitative analyzes of the data were performed.ResultsConcordance rates with tissue biopsy were 40.4% and 59.6% for the qualitative and quantitative methods, respectively. Bone metastasis showed a statistically significant correlation with ctDNA detection (odds ratio 3.985, 95% confidence interval [CI] 1.027–15.457; P = 0.046). Progression‐free survival (PFS) was significantly shorter in the group detected with ctDNA than in the undetected ctDNA group (median PFS 9.8 vs. 20.7 months; hazard ratio [HR] 2.30, 95% CI 1.202–4.385; P = 0.012). Detection of ctDNA before treatment with EGFR‐TKIs (HR 2.388, 95% CI 1.138–5.014; P = 0.021) and extra‐thoracic lymph node metastasis (HR 13.533, 95% CI 2.474–68.747; P = 0.002) were independently associated with PFS. Six of 11 patients (45.5%) monitored by serial sampling showed a dynamic change in ctDNA prior to disease progression.ConclusionQuantitative testing can increase the sensitivity of the ctDNA detection test. Patients with detectable ctDNA had significantly shorter PFS after receiving EGFR‐TKIs than those with undetectable ctDNA. Tumor burden may be associated with plasma ctDNA detection. A shorter PFS was associated with detection of ctDNA and extra‐thoracic lymph node metastasis. Dynamic changes in the ctDNA level may help predict clinical outcomes.
Sensitivity of binomial N‐mixture models to overdispersion: The importance of assessing model fit

Published: July 2018

Abstract

Binomial N‐mixture models are commonly applied to analyse population survey data. By estimating detection probabilities, N‐mixture models aim at extracting information about abundances in terms of absolute and not just relative numbers. This separation of detection probability and abundance relies on parametric assumptions about the distribution of individuals among sites and of detections of individuals among repeat visits to sites. Current methods for checking assumptions are limited, and their computational complexity has hindered evaluations of their performance.

We use simulations and a case study to assess the sensitivity of binomial N‐mixture models to overdispersion in abundance and in detection, develop computationally efficient graphical goodness of fit checks to detect it, and evaluate the ability of the checks to identify overdispersion.

The simulations show that if the parametric assumptions are not exact the bias in estimated abundances can be severe: underestimation if there is overdispersion in abundance relative to the fitted model and overestimation if there is overdispersion in detection. Our goodness‐of‐fit checks performed well in detecting lack of fit when the abundance distribution was overdispersed, but struggled to detect lack of fit when detections were overdispersed. We show that the inability to detect lack of fit due to overdispersed detection is caused by a fundamental similarity between N‐mixture models with beta‐binomial detections and N‐mixture models with negative binomial abundances.

The strong biases that can occur in the binomial N‐mixture model when the distribution of individuals among sites, or the detection model, is mis‐specified implies that checking goodness of fit is essential for sound inference about abundance. To check the assumptions we provide computationally efficient goodness of fit checks that are available in an R‐package nmixgof. However, even when a binomial N‐mixture model appears to fit the data well, estimates are not robust in the presence of overdispersion. We show that problems can occur even when estimated detection probabilities are high, and that previously reported problems with negative binomial models cannot always be diagnosed by checking the sensitivity of abundance estimates to numerical cutoff values used in likelihood computations.
The Impact of Alcohol and Social Context on the Startle Eyeblink Reflex
Authors: Kang Dahyeon , Bresin Konrad , Fairbairn Catharine E. 
Published: July 2018

BackgroundResearchers have long sought to understand how individuals respond to alcohol in social settings with the aim of elucidating pathways of risk for alcohol use disorder (AUD). But studies that incorporate a social context are still outnumbered by those that examine alcohol's subjective effects among participants drinking alcohol in isolation. Further, perhaps due to the challenges of capturing automatic affective processes in these settings, prior studies of alcohol response in social context have relied mainly on self‐report measures, and so relatively little is known about alcohol's psychophysiological effects in social settings.MethodsUsing a novel paradigm that integrated alcohol‐administration procedures, startle methodology, and social context, this study examined the impact of alcohol and social context on startle eyeblink reflex among 40 social drinkers.ResultsResults indicated that there was a significant effect of group presence, indicating that startle magnitude was larger when people were alone than with others. There was a significant group presence‐by‐alcoholic beverage interaction, with the effect of alcohol being significantly larger when people were alone versus with others. These effects were found both for the startle habituation data and during the picture‐viewing task.ConclusionsResults of this study highlight the importance of considering the presence of other individuals for understanding alcohol response and mechanisms of AUD risk. Findings are discussed in light of both emotional and cognitive correlates of startle reflex magnitude. Future research should examine these effects within larger samples of participants and further explore mechanisms that might underlie these effects.

SummaryThe use of cell salvage is recommended when it can be expected to reduce the likelihood of allogeneic (donor) red cell transfusion and/or severe postoperative anaemia. We support and encourage a continued increase in the appropriate use of peri‐operative cell salvage and we recommend that it should be available for immediate use 24 h a day in any hospital undertaking surgery where blood loss is a recognised potential complication (other than minor/day case procedures).
