AbstractThe population dynamics of human-to-mosquito malaria transmission in the field has important implications for the genetics, epidemiology and control of malaria. The number of oocysts in oocysts positive mosquitoes developing from a single, naturally acquired infectious blood meal (herein referred to as parasite exposure) greatly influence the effectiveness of transmission blocking interventions but still remains poorly documented. During a year-long analysis of malaria parasite transmission in Burkina Faso we caught and dissected wild malaria vectors to assess Plasmodium oocysts prevalence and load (the number of oocysts counted in mosquitoes with detectable oocysts) and the prevalence of salivary gland sporozoites. This was compared to malaria endemicity in the human population assessed in cross-sectional surveys. Data was analyzed using a novel transmission mathematical model to estimate the per-bite transmission probability and the average parasite exposure of mosquitoes for each location. Observed oocysts load and estimated parasite exposure in naturally infected mosquitoes is substantially higher than previous estimates (ranging from 3.2 to 24.5 according to seasons and locations) and indicates a strong positive association between parasite exposure of mosquitoes and parasite prevalence in human. This work suggests that highly infected mosquitoes may have a greater influence on the epidemiology and genetics of the parasite and that novel partially effective transmission blocking interventions may become more effective at halting transmission as parasite exposure is diminished.

AbstractInformation on the buoyancy of eggs and larvae from deep-sea species is rare but necessary for explaining the position of non-swimming larvae in the water column. Due to embryonic morphology and ecology diversities, egg buoyancy has important variations within one species and among other ones. Nevertheless, it has hardly been explored if this buoyancy variability can be a strategy for deep-sea larvae to optimize their transport beyond their spawning areas. In the northwestern Mediterranean Sea, protozoea and mysis larvae of the commercial deep-sea shrimp Aristeus antennatus were recently found in upper layers, but to present, earlier stages like eggs and nauplii have not been collected. Using a Lagrangian transport model and larval characteristics, we evaluate the buoyancy and hydrodynamic effects on the transport of A. antennatus larvae in the northwestern Mediterranean Sea. The transport models suggested that 75% of buoyant eggs released between 500 and 800 m depth (i.e., known spawning area), reached the upper water layers (0–75 m depth). Then, according to the modeled larval drifts, three spawning regions were defined in the studied area: 1) the northern part, along a continental margin crossed by large submarine canyons; 2) the central part, with two circular circulation structures (i.e., eddies); and 3) the southern part, with currents flowing through a channel. The number of larvae in the most upper layer (0–5 m depth) was higher if the larval transport model accounted for the ascent of eggs and nauplii (81%) instead of eggs reaching the surface before hatching (50%). The larvae reaching the most water upper layer (0–5 m depth) had higher rates of dispersal than the ones transported below the surface layer (deeper than 5 m depth). The results of larval dispersal simulations have implications for the understanding of A. antennatus larval ecology and for management decisions related to the shrimp fisheries in the northwestern Mediterranean Sea.
Not a solo ride: co-constructed peer mentoring for early-career educational leadership faculty
Authors: Morton Benterah C. , Gil Elizabeth 
Published: September 2019

PurposeThe purpose of this paper is to describe the origins of a co-constructed peer-mentoring model designed by and for early-career faculty representing historically underrepresented groups in the field of educational leadership. The model, which includes components of the multicultural feminist model of mentoring, pays specific attention to early-career faculty development and well-being and outlines the need for and benefits of peer-mentoring programs.Design/methodology/approachThis qualitative study details the experiences of the development and implementation of a peer-mentoring program based on a review of literature that points out the need to provide mentoring opportunities for early-career educational leadership faculty, from historically underrepresented populations, and further posits peer-mentoring as an avenue to enhance faculty development and well-being.FindingsFaculty representing historically underrepresented groups often experience challenges related to their identities, alongside the general pressures of working toward tenure. Peer-mentoring groups provide support with which to navigate these challenges. Peer-mentor groups are a supplement to other professional groups and interactions within departments and institutions.Practical implicationsThe model has implications of being able to prepare institutional leaders to work toward institutionalizing mentoring programs that take into consideration invisible labor while promoting professional growth and personal wellness, thereby increasing the satisfaction and retention of faculty.Originality/valueThis peer-mentoring model can be used as a tool to leverage collective support, rather than emphasize individual success. As a support vehicle, it can foster a cultural change within the field of educational leadership that supports collaboration over competition.
From “Technical Newbies” to “Optimistic Politicians”
Authors: Prater James , Kirytopoulos Konstantinos , Ma Tony 
Published: September 2019

PurposeDespite the advent of sophisticated control methods, there are still significant issues regarding late delivery of information technology projects. The purpose of this paper is to investigate the common causes of scheduling problems specifically in the information technology projects context.Design/methodology/approachThrough a quantitative research, the importance of those causes, as well as the underpinning factors driving them, is explored. The causes are ranked according to their relative important index, and exploratory factor analysis is employed to reveal underlying dimensions (factors) of these causes.FindingsFrom the analysis, four factors were extracted, namely, “Dataless Newbie,” “Technical Newbie,” “Pragmatic Futurist” and “Optimistic Politician.” These factors explain the different latent conditions that lead to scheduling problems in information technology projects.Practical implicationsThe key contribution of this research is that it enlightens the latent conditions underpinning scheduling problems. Also, the evidence provides that schedule development for information technology projects is impacted by the same causes that impact engineering projects, and that applying a number of mitigation techniques widely used within the engineering area, such as reference class, would, no doubt, not only improve information technology schedules but also reduce the political pressures on the project manager.Originality/valueThis research provides a valuable insight into understanding the underlying factors for poor project estimation.
A review of artificial intelligence based risk assessment methods for capturing complexity-risk interdependencies
Authors: Afzal Farman , Yunfei Shao , Nazir Mubasher , Bhatti Saad Mahmood 
Published: September 2019

PurposeIn the past decades, artificial intelligence (AI)-based hybrid methods have been increasingly applied in construction risk management practices. The purpose of this paper is to review and compile the current AI methods used for cost-risk assessment in the construction management domain in order to capture complexity and risk interdependencies under high uncertainty.Design/methodology/approachThis paper makes a content analysis, based on a comprehensive literature review of articles published in high-quality journals from the years 2008 to 2018. Fuzzy hybrid methods, such as fuzzy-analytical network processing, fuzzy-artificial neural network and fuzzy-simulation, have been widely used and dominated in the literature due to their ability to measure the complexity and uncertainty of the system.FindingsThe findings of this review article suggest that due to the limitation of subjective risk data and complex computation, the applications of these AI methods are limited in order to address cost overrun issues under high uncertainty. It is suggested that a hybrid approach of fuzzy logic and extended form of Bayesian belief network (BBN) can be applied in cost-risk assessment to better capture complexity-risk interdependencies under uncertainty.Research limitations/implicationsThis study only focuses on the subjective risk assessment methods applied in construction management to overcome cost overrun problem. Therefore, future research can be extended to interpret the input data required to deal with uncertainties, rather than relying solely on subjective judgments in risk assessment analysis.Practical implicationsThese results may assist in the management of cost overrun while addressing complexity and uncertainty to avoid chaos in a project. In addition, project managers, experts and practitioners should address the interrelationship between key complexity and risk factors in order to plan risk impact on project cost. The proposed hybrid method of fuzzy logic and BBN can better support the management implications in recent construction risk management practice.Originality/valueThis study addresses the applications of AI-based methods in complex construction projects. A proposed hybrid approach could better address the complexity-risk interdependencies which increase cost uncertainty in project.
Generation Y consumer online repurchase intention in Bangkok
Authors: Zhu Bing , Kowatthanakul Suwanna , Satanasavapak Punnaluck 
Published: September 2019

Purpose
The rapid growth of e-commerce has encouraged online retailers to adapt to the purchase behaviour of Generation Y consumers. For this purchase, the purpose of this paper is to investigate Generation Y online consumer repurchase intention in Thai context based on Stimuli-Organism-Response (SOR) model.

Design/methodology/approach
Data were used to test the hypotheses that Generation Y consumer online response is influenced by online environment cues and organism. In total, 401 questionnaires were collected in Bangkok through judgemental sampling and convenient sampling. SPSS 24 was used to analyse Generation Y consumers’ demographic information and reliability test. Amos 24 was utilized to examine measurement model and structural equation model.

Findings
The findings finally revealed that website security presents the strongest influence on Generation Y consumers trust. Also, online promotion possesses the weakest association with Generation Y consumers trust. More importantly, Generation Y consumer online repurchase intention is positively influenced by the degree of trust they have towards websites. The implications of the findings for marketers are discussed.

Research limitations/implications
The empirical data are limited to generate findings from a limited number of Generation Y consumers in Bangkok only. Also, the study limits itself to explore only inter-relationship in the scope of SOR.

Practical implications
It is suggested that in order to draw attention from and retain Generation Y consumers, online retailers should aim at strengthening trust-building in the online buyer–seller context as well as a dynamic promotional campaign. Moreover, a constellation of relevant marketing strategies is recommended.

Originality/value
Since there is a lack of implementation of SOR model based on the Thai context, this paper fills the gap by illustrating how SOR works in Thailand with updating findings.
Dividend policy and earnings quality in Vietnam
Authors: Nguyen Trang Thi Ngoc , Bui Phuong Kim 
Published: September 2019

Purpose
The purpose of this paper is to examine the relationship between dividend policy and earnings quality of Vietnamese listed firms.

Design/methodology/approach
The sample includes firms listed on Vietnam stock exchange during the period between 2010 and 2016. Two measures of earnings quality are the annual firm-specific absolute value of residuals from Dechow and Dichev’s (2002) model and from Dechow and Dichev (2002) as modified by McNichols’s (2002) model. The firms’ dividend policy is captured by dividend paying status. This is a dummy variable that takes the value of 1 if the firm pays dividends and 0 otherwise. In addition, dividend yield and dividend payout ratio, which are continuous variables, are also used in this paper as alternative proxies for dividend policy.

Findings
Using panel data analysis, this paper documents that dividend payers have higher earnings quality than dividend non-payers. Dividends are an indicator of earnings quality. These findings are consistent with prior studies. After controlling for variables that may be related to earnings quality as well as for the year and industry fixed effects, this relation remains unchanged. In addition, this result is also robust after controlling for firm fixed effects.

Originality/value
This paper offers the empirical evidence on the relation between dividend policy and earnings quality in Vietnam, which is a frontier market.
You touched it and I’m relieved! The effect of online review’s tactile cues on consumer’s purchase intention
Authors: Huang Jing , Guo Yulang , Wang Cheng , Yan Lei 
Published: September 2019

Purpose
The purpose of this paper is to examine the role of online review’s tactile cues in consumer’s purchase intention, given the absence of direct experience in online shopping.

Design/methodology/approach
Based on four empirical studies, the authors examine the role of online review’s tactile cues in consumer’s purchase intention. A secondary data analysis on Taobao and three experiments were conducted.

Findings
First, this research demonstrates that tactile cues in online reviews are sure to have a significant influence on consumers’ purchase intention. Second, the purchase intention of consumers is easily influenced by the reviews of holistic tactile cues of the search product, which affects the final purchase intention through the way of outcome simulation. Consumers’ purchase intention is also easily influenced by concrete tactile cues of experience product, which affects the final purchase intention through the way of process simulation. Temporal distance is the boundary condition.

Practical implications
A seller should manage the order of online review or labels related to corresponding tactile cues, in order to encourage consumers to comment on the relevant tactile features. Besides, in the aspect of website design, a seller can also encourage consumers to image about the process and the result of using so as to promote his sales volume.

Social implications
The conclusion may give a solution on how to deal with the absence of direct experience in online shopping.

Originality/value
There has been little research about the influences of others' tactile behaviors on consumers' behaviors. The authors focus the other tactile experience in online review. The previous studies on online reviews focus on the its influences of valence, quantity and sentiment polarity on the usefulness of reviews and sales volume. However, few studies are explored on contents of reviews. The authors focus on the content such as tactile cues.
How does intellectual capital align with cyber security?
Authors: Renaud Karen , Von Solms Basie , Von Solms Rossouw 
Published: September 2019

PurposeThe purpose of this paper is to position the preservation and protection of intellectual capital as a cyber security concern. The paper outlines the security requirements of intellectual capital to help boards of directors (BoDs) and executive management teams to understand their responsibilities and accountabilities in this respect.Design/methodology/approachThe research methodology is desk research. In other words, we gathered facts and existing research publications that helped us to define key terms, to formulate arguments to convince BoDs of the need to secure their intellectual capital and to outline actions to be taken by BoDs to do so.FindingsIntellectual capital, as a valuable business resource, is related to information, knowledge and cyber security. Hence, preservation thereof is also related to cyber security governance and merits attention from BoDs.Research limitations/implicationsThis paper clarifies BoDs intellectual capital governance responsibilities, which encompass information, knowledge and cyber security governance.Practical implicationsThe authors hope that BoDs will benefit from the clarifications, and especially from the positioning of intellectual capital in cyber space.Social implicationsIf BoDs know how to embrace their intellectual capital governance responsibilities, this will help to ensure that such intellectual capital is preserved and secured.Originality/valueThis paper extends a previous paper published by Von Solms and Von Solms, which clarified the key terms of information and cyber security, and the governance thereof. The originality and value is the focus on the securing of intellectual capital, a topic that has not yet received a great deal of attention from security researchers.
Unpacking the black box of systemic risks in banking
Authors: Hoffmann Christian Hugo 
Published: September 2019

Purpose Systemic risks affect financial market participants in many ways. However, the literature insists firmly that they are and, in fact, should be of little concern to (private) banks (as opposed to regulators). The purpose of this paper is to argue for the relevance of systemic risks for private banks as opposed to regulators only by making use of causal loop models as being traditionally used in the discipline of systems dynamics. In contrast to the starting point for all common risk-management frameworks in banks, which is the classification of risks into risk categories, the authors show that risk has been compartmentalized too much and provide a strong case for a really holistic approach.

Design/methodology/approach Systems thinking, causal loop models and conceptual approach.

Findings Relevance of systemic risks for private banks as opposed to regulators only. In contrast to the starting point for all common risk-management frameworks in banks, which is the classification of risks into risk categories, the authors show that risk has been compartmentalized too much and provide a strong case for a really holistic approach, which stems from using explanatory models such as causal loop diagrams. On top of that more explanatory models ought to be used for risk management purposes while banks currently rely too much on statistical-descriptive approaches.

Originality/value Integration of systems thinking into risk management, which is novel: in contrast to the starting point for all common risk-management frameworks in banks, which is the classification of risks into risk categories, the authors show that risk has been compartmentalized too much and provide a strong case for a really holistic approach.

Published: September 2019

SummaryDelirium is a common complication following hip fracture surgery. We introduced a peri‐operative care bundle that standardised management in the emergency department, operating theatre and ward. This incorporated: use of fascia iliaca blocks; rationalisation of analgesia; avoidance of drugs known to trigger delirium; a regular education program for staff; and continuous auditing of compliance. The study was conducted between June 2017 and December 2018. We recruited 150 patients before (control group) and 150 patients after (care bundle group) the introduction of the care bundle. In patients having surgery for a hip fracture, there was a lower incidence of delirium on the third postoperative day in the care bundle group compared with the control group (33 patients (22%) vs. 49 patients (33%)), respectively; p = 0.04). Patients in the care bundle group had an adjusted OR of 2.2 (95%CI 1.1–4.4) (p = 0.03) for the avoidance of delirium on the third postoperative day. There was no difference between groups for the secondary outcome measures (measured at 30 days postoperatively) including: all‐cause mortality; composite morbidity; institutionalisation; and walking status. During the study period, compliance with elements of the care bundle improved in the emergency department (49 patients (33%) compared with 85 patients (59%); p < 0.001) and anaesthetic department (40 patients (27%) compared with 104 patients (69%); p < 0.001), while orthogeriatrics maintained a high level of compliance (140 patients (93%) compared with 143 patients (95%); p = 0.45). There was a clinically and statistically significant reduction in the incidence of delirium following hip fracture surgery in patients treated with a multidisciplinary care bundle.
Reduced regional strain rate is the most accurate dysfunction in predicting culprit lesions in patients with acute coronary syndrome

Published: September 2019

SummaryBackground and AimPredicting culprit lesions in acute coronary syndrome (ACS) could be a challenge. The aim of this study was to assess the accuracy of regional wall motion abnormalities (RWMA) using various echocardiographic techniques and ECG changes in predicting the culprit coronary lesion in a group of patients with ACS.MethodsIn 80 consecutive patients with ACS (age 55·7 ± 9·4 years, 77% male, 15% with CCS Angina III), an echocardiographic examination of left ventricle (LV) RWMA, tissue Doppler imaging (TDI) and speckle tracking myocardial strain and strain rate (SR) were performed before intervention.ResultsOf the 80 patients, one‐vessel stenosis (>70%) was present in 53 (66%), two‐vessel disease in 12 (15%) and multivessel disease in 15 patients (19%). About 51% of patients had hypertension, 40% diabetes and 23% dyslipidaemia. There was no relationship between individual segmental RWMA and SR. Mean regional SR, but not peak strain, correlated with culprit lesion branch: left anterior descending – LAD (r = 0·35, P = 0·005), circumflex LCx (r = 0·32, P = 0·03) and right coronary RCA (r = 0·37, P = 0·01). Only ECG changes in the LAD territory (r = 0·26, P = 0·04) correlated with the culprit lesion. SR of LAD territories ≤−0·74 was 71% sensitive and 70% specific (AUC = 0·70, CI = 0·67–0·93, P = 0·01), SR of LCx territories of ≤−0·67 was 75% sensitive and 63% specific (AUC = 0·72, CI = 0·58–0·87, P = 0·02) and SR of RCA territories ≤−0·83 was 73% sensitive and 71% specific (AUC = 0·80, CI = 0·66–0·93, P = 0·001) in predicting significant stenosis. SR was more accurate than all other techniques in predicting the culprit lesion.ConclusionIn ACS, mean regional speckle tracking SR is more sensitive than peak strain, TDI, ECG changes and wall motion abnormalities in detecting significant coronary artery stenosis.
