Authors: Dietrich Timo , Rundle-Thiele Sharyn , Kubacki Krzysztof , Durl James , Gullo Matthew J. , Arli Denni , Connor Jason P. 
Published: August 2019

Purpose
The purpose of this paper is to present an innovative reflexive process evaluation method for a social marketing programme featuring an innovative virtual reality (VR) simulation experience for adolescents.

Design/methodology/approach
A process evaluation framework focusing on three key elements – context, implementation and mechanisms of impact – was followed in this study. In total, 374 participants (mean age: 15.2 years, 58 per cent female) completed outcome evaluation surveys before and after the programme delivery, and 300 participants completed qualitative feedback forms following their participation in the VR component of the programme.

Findings
A process evaluation delivers insights beyond those attained in outcome evaluations, enhancing the understanding of factors contributing to programme success or failure that can be used to improve future programme iterations. The VR experience demonstrated high satisfaction scores with users, and the findings demonstrate the importance of a multi-disciplinary and industry partnered programme approach to support VR implementation and delivery.

Research limitations/implications
This research demonstrates that additional learnings are obtained from a process evaluation. The findings are limited to one specific research programme, and the outcome effects of the VR simulation have not been assessed in isolation.

Practical implications
The methods outlined in this paper offer a process evaluation tool that can be used by marketers and other practitioners to reflect on programme success or failure to enhance core offerings.

Originality/value
The application of Moore et al.’s (2015) process evaluation framework delivers a reflexive research tool that can be applied to critically consider three key elements: context, implementation and mechanisms of impact of developed programmes. VR’s capacity to provide a satisfying and highly valued programme resource that participants value for its realistic, novel and immersive experiential learning experience was demonstrated.

Authors: Raza Jawad , Mebarek-Oudina Fateh , Mahanthesh B. 
Published: August 2019

Purpose
The purpose of this paper is to present an exploration of multiple slips and temperature dependent thermal conductivity effects on the flow of nano Williamson fluid over a slendering stretching plate in the presence of Joule and viscous heating aspects. The effectiveness of nanoparticles is deliberated by considering Brownian moment and thermophoresis slip mechanisms. The effects of magnetism and radiative heat are also deployed.

Design/methodology/approach
The governing partial differential equations are non-dimensionalized and reduced to multi-degree ordinary differential equations via suitable similarity variables. The subsequent non-linear problem treated for numerical results. To measure the amount of increase/decrease in skin friction coefficient, Nusselt number and Sherwood number, the slope of linear regression line through the data points are calculated. Statistical approach is implemented to analyze the heat transfer rate.

Findings
The results show that temperature distribution across the flow decreases with thermal conductivity parameter. The maximum friction factor is ascertained at stronger magnetic field.

Originality/value
In the current paper, the magneto-nano Williamson fluid flow inspired by a stretching sheet of variable thickness is examined numerically. The rationale of the present study is to generalize the studies of Mebarek-Oudina and Makinde (2018) and Williamson (1929).
An overview of fish drying kinetics
Authors: Adeyeye Samuel Ayofemi Olalekan 
Published: August 2019

PurposeFishes are important sources of good and high-quality protein in developing countries. Spoilage and keeping quality of fish especially in the tropics is temperature dependence as high temperature and relative humidity accelerate the process of spoilage and fish keeping quality. Fish dehydration removed moisture and extended the shelf life of dried fish. Drying involves removal of moisture from fish as a result of heat and mass transfer done under controlled conditions. This study delves into various drying techniques and drying kinetics of fish.Design/methodology/approachThe review examines fish drying kinetics and the various drying models applicable to fish drying.FindingsThis review showed that moisture content and colour of dried fish are affected by time and power level. It was also found that the moisture content of the dried fish varied according to the drying method used. Also, as drying power and drying rate varied inversely with drying time. Eight different thin layer drying models were examined for evaluation of drying data for all the experimental conditions involving fish drying. It was found that the quality of the dried fish decreased with drying. Higher values of effective moisture diffusivity have been found to increase moisture velocity within fish samples which improve removal of moisture to reach equilibrium moisture content at specified relative humidity. However, based on this, effective moisture diffusivity could be a useful parameter to design an effective drying method in terms of time, energy consumption and cost to prolong the storage life of dried fish samples. Drying kinetics and different drying models were considered and explained. The use of these models was considered to be important in choosing appropriate drying conditions for effective drying and to get good quality dried fish samples.Research limitations/implicationsThe review considers few available literatures on the subject matter.Practical implicationsThe review explores the possibility of creating more awareness for more in-depth research on fish drying kinetics and their usefulness in fish preservation.Originality/valueThis outcome of this study is important to researchers, policymakers and regulatory agencies in developing countries on fish preservation.

Sports sentiment and behavior of stock prices: a case of T-20 and IPL cricket matches
Authors: Hiremath Gourishankar S. , Venkatesh Hari , Choudhury Manish 
Published: August 2019

Purpose
The purpose of this paper is to examine whether the emotions and sentiments related to the outcome of the sporting event influence the investment making process.

Design/methodology/approach
This study uses the data on stock prices of firms sponsoring the Indian premier league (IPL) teams and data on Indian stock market. The event-study frameworks along with autoregressive moving average and GMM regression are employed to empirical quantify the impacts of the performance of the IPL teams on the stock market returns of the sponsors’ stocks and response of Indian stock market to the outcome of T-20 international matches.

Findings
The paper finds that the team winning IPL title in a season has a positive impact on the returns of the sponsors’ stocks of a particular team, whereas loss of team has a negative impact on returns. The outcome of the cricket matches played by team India in the T-20 has a negligible effect on the Indian stock market.

Practical implications
The finding of the study implies the coexistence of emotions and rationality at different points in time and the relevance of adaptive market hypothesis to explain such time-varying behavior.

Originality/value
The present investigation is first of its kind to test whether the performance of the IPL cricket team can influence the stock returns of the sponsors. This research shows that sentiment related to sports event such as cricket influences the decision-making process and thus affects underlying stock prices.
Change is not just analogue but a data-driven vicious circle
Authors: Hipps Charles 
Published: August 2019

Purpose
Change is no longer an event in HR. Competition is tougher than ever, and this battle for top talent is a vicious cycle that doesn't stop but reinvents itself all the time. The recruitment market needs to be more responsive to the continuous cycle of innovation and recognise the increasingly competitive marketplace that is rapidity getting tighter.

Design/methodology/approach
With more than 20 years as the founder of a leading recruitment technology vendor, the detail and content supplied in the feature are all of the author’s own thoughts and experiences, drawn from his own expertise and learning from others he has met en route.

Findings
More often than not, recruitment teams are doing what they have always done – seeing the same candidates and visiting the same events. Change, or more specifically in this case, technology, actually has the ability to speed up the process, enhance the candidate experience and give time back to recruiters to spend with the candidates.

Originality/value
It is widely known that talented people have higher expectations and opportunities than ever before. That makes it crucial for companies to reach them, deliver a highly engaging candidate experience and nurture a relationship well ahead of open opportunities.

Abstract

Temporal fluctuations in growth rates can arise from both variation in age‐specific vital rates and temporal fluctuations in age structure (i.e. the relative abundance of individuals in each age‐class). However, empirical assessments of temporal fluctuations in age structure and their effects on population growth rate are relatively rare. Most research has focused on understanding the contribution of changing vital rates to population growth rates and these analyses routinely assume that: (a) populations have stable age distributions, (b) environmental influences on vital rates and age structure are stationary (i.e. the mean and/or variance of these processes does not change over time), and (c) dynamics are independent of density.

Here we quantified fluctuations in age structure and assessed whether they were stationary for four populations of free‐ranging vertebrates: moose (observed for 48 years), elk (15 years), tawny owls (15 years) and grey wolves (17 years). We also assessed the extent that fluctuations in age structure were useful for predicting annual population growth rates using models which account for density dependence.

Fluctuations in age structure were of a similar magnitude to fluctuations in abundance. For three populations (moose, elk, owls), the mean and the skew of the age distribution fluctuated without stabilizing over the observed time periods. More precisely, the sample variance (interannual variance) of age structure indices increased with the length of the study period, which suggests that fluctuations in age structure were non‐stationary for these populations – at least over the 15‐ to 48‐year periods analysed.

Fluctuations in age structure were associated with population growth rate for two populations. In particular, population growth varied from positive to negative for moose and from near zero to negative for elk as the average age of adults increased over its observed range.

Non‐stationarity in age structure may represent an important mechanism by which abundance becomes non‐stationary – and therefore difficult to forecast – over time‐scales of concern to wildlife managers. Overall, our results emphasize the need for vertebrate populations to be modelled using approaches that consider transient dynamics and density dependence and that do not rely on the assumption that environmental processes are stationary.

Canadian beef and dairy farmers’ attitudes towards animal vaccines
Authors: Ugochukwu Albert I. , Phillips Peter W. B. 
Published: August 2019

The willingness to pay (WTP) approach is increasingly being used in different disciplines to assess peoples’ readiness to accept change. This paper assesses the potential for two subunit vaccines for the prevention and control of bovine tuberculosis and paratuberculosis in cattle. A survey of beef and dairy farmers was conducted across Canada to identify factors that influence their WTP for subunit vaccines. Estimated results of the interval‐data model indicate that the size of a farmer’s cattle herd, neighbourhood effect, and buyer recommendations for vaccination significantly influence farmers’ WTP while veterinarians appear to be the most critical pathway for farmers to source information on new vaccine options. The mean willingness to pay amounts for both vaccines reveals that farmers are likely to use the vaccines if the costs are kept at reasonable level.
Fight or flight: Integral emotions and violent intentions
Authors: Barnum Timothy C. , Solomon Starr J. 
Published: August 2019

AbstractThe effect of proximate emotions on risk perceptions is of central importance to criminal decision‐making theory, but has been understudied. We investigate the role of two integral (situational specific) emotional responses, anger and fear, in a decision‐making context regarding the choice to commit assault. We draw on dual‐process models of information processing and appraisal theory to propose a theoretical model in which integral emotions influence decisions and behavior. Using data from an experiment embedded in a survey to a nationwide sample of adults (N = 804), we test the interrelated roles of anger, fear, and traditional rational choice considerations on the intention to commit assault. We find a strong direct association between emotions and intentions to commit assault. Additionally, anger and fear moderate the effect of cognitive deliberations on behavioral intentions and provide a lens through which to evaluate a criminogenic opportunity.
Acrylamide in food: Progress in and prospects for genetic and agronomic solutions
Authors: Raffan Sarah , Halford Nigel G. 
Published: August 2019

AbstractAcrylamide is a processing contaminant and Group 2a carcinogen that was discovered in foodstuffs in 2002. Its presence in a range of popular foods has become one of the most difficult problems facing the food industry and its supply chain. Wheat, rye and potato products are major sources of dietary acrylamide, with biscuits, breakfast cereals, bread (particularly toasted), crispbread, batter, cakes, pies, French fries, crisps and snack products all affected. Here we briefly review the history of the issue, detection methods, the levels of acrylamide in popular foods and the risk that dietary acrylamide poses to human health. The pathways for acrylamide formation from free (non‐protein) asparagine are described, including the role of reducing sugars such as glucose, fructose and maltose and the Maillard reaction. The evolving regulatory situation in the European Union and elsewhere is discussed, noting that food businesses and their suppliers must plan to comply not only with current regulations but with possible future regulatory scenarios. The main focus of the review is on the genetic and agronomic approaches being developed to reduce the acrylamide‐forming potential of potatoes and cereals and these are described in detail, including variety selection, plant breeding, biotechnology and crop management. Obvious targets for genetic interventions include asparagine synthetase genes, and the asparagine synthetase gene families of different crop species are compared. Current knowledge on crop management best practice is described, including maintaining optimum storage conditions for potatoes and ensuring sulphur sufficiency and disease control for wheat.
Effects of investor tax heterogeneity on stock prices and trading behaviour around the ex‐dividend day: the case of Australia
Authors: Le Nguyen Ngoc Anh , Yin Xiangkang , Zhao Jing 
Published: August 2019

AbstractUsing a sample of Australian stocks during the 1996–2014 period, this study examines how tax heterogeneity between domestic and foreign investors affects trading behaviour and stock prices around the ex‐dividend day. Domestic investors prefer dividends and tend to buy stocks cum‐dividend and sell them ex‐dividend whereas foreign investors tend to trade in the opposite direction. Abnormal trading turnover increases with tax heterogeneity. Moreover, stocks with a larger domestic investor base are associated with a higher price drop‐off ratio on the ex‐dividend day and higher market value of franking credits. Overall, our findings support the dynamic dividend clientele hypothesis.
Australian processionary caterpillars, Ochrogaster lunifer Herrich‐Schäffer (Lepidoptera: Notodontidae), comprise cryptic species
Authors: Mather Andrew , Zalucki Myron P , Farrell Julianne , Perkins Lynda E , Cook Lyn G 
Published: August 2019

AbstractThe bag shelter moth, Ochrogaster lunifer Herrich‐Schäffer, 1855 (Thaumetopoeinae), is abundant and widespread throughout Australia where its larvae have been reported to feed mostly on Acacia and eucalypts. The larvae, known as processionary caterpillars, build silken nests on their host plants either on the ground at the base of the plant (Acacia) or above ground on the trunk or among the canopy (Acacia and eucalypts). The caterpillars are medically important in that they shed tiny setae that can cause dermatitis and other health problems in humans and other mammals, including amnionitis and foetal loss in horses. Despite reports of behavioural, ecological and morphological differences between ground and canopy nesters, caterpillars of all nest types and hosts are currently considered to belong to one species. Here, we use DNA sequence data from the mitochondrial and nuclear genomes of caterpillars taken from different nest types in eastern Australia to determine whether there is evidence for there being more than one species. We find significant genetic divergence between caterpillars from different nest types despite occurrence in sympatry at multiple sites, indicative of a lack of gene flow and the presence of at least two reproductively isolated species. Given the range of hosts and nest locations within hosts throughout Australia, further sampling is needed to determine just how many species there are under the current concept of O. lunifer.
Eight‐fold path to attain laparoscopic totally extraperitoneal (TEP) hernia repair Nirvana – a standardized technique to reduce the learning curve of surgical residents
Authors: Yeo Danson , Kaushal Sanghvi , Oo Aung M. , Rao Jaideepraj 
Published: August 2019

AbstractIntroductionLaparoscopic totally extraperitoneal (TEP) hernia repair remains technically challenging due to the steep learning curve and unfamiliar territory. This paper describes an eight‐step standardized technique of laparoscopic TEP hernia repair that is easily reproducible, thus reducing the learning curve.Materials and Surgical TechniqueThe eight steps are as follows: (a) creation of the pneumo pre‐peritoneal space; (b) identify the pubis symphysis; (c) identify the inferior epigastric vessels; (d) lateral to medial dissection of the hernia sac; (e) identification of cord structures and triangle of doom/pain; (f) herniotomy; (g) parietalization of the hernia sac; (h) placement and fixation of the mesh.DiscussionThe learning curve of laparoscopic TEP can be decreased by proctoring, standardization of the procedure and having a formal set of operative steps that residents can follow and easily repeat.

AbstractThe objective of this study was to evaluate the effects of using encapsulated nitrate product (ENP) replacing soybean meal in diets differing in concentrate to forage ratio on ruminal fermentation and methane production in vitro using a semi‐automatic gas production technique. Eight treatments were used in a randomized complete design with a 2 × 4 factorial arrangement: two diet (20C:80F and 80C:20F concentrate to forage ratio) and four levels of ENP addition (0%, 1.5%, 3.0%, and 4.5% of DM) replacing soybean meal. There was a diet × ENP interaction (p = 0.02) for methane production. According to ENP addition, diets with 80C:20F showed more intense reduction on methane production that 20C:80F. A negative linear effect was observed for propionate production with ENP addition in diet with 80C:20F and to the relative abundance of methanogens Archaea, in both diet. The replacement of soybean meal by ENP in levels up to 3% of DM inhibited methane production due to a reduction in the methanogens community without affecting the organic matter degradability. However, ENP at 4.5% of DM level affected fiber degradability, abundance of cellulolytic bacteria, and propionic acid production, indicating that this level of inclusion is not recommended for ruminant production.
