Super heroes, villains, and politics
Authors: Torres Francisco Luis , Tayne Kelsey 
Published: October 2017

PurposeThe purpose of this paper is to discuss how the superhero genre, when couched in a space and project that seek to act as a counter-world and is rooted in the life experiences of youth, can allow Latinx elementary school students the opportunity to create counter-stories. Such stories facilitated the process of creating “critical hope” in relation to oppressive political discourses.Design/methodology/approachThis is a qualitative study conducted at an afterschool club in the Western USA. Using the superhero genre, elementary school students, grades third-fifth, participated in a project in which they created superhero and villain narratives set in their community.FindingsThe authors found that the superhero genre supported some Latinx students to develop counter-stories that engaged with and resisted the heightened xenophobic and racist discourse appropriated by then US presidential candidate Donald Trump in the context of the 2016 presidential campaign. These counter-stories allowed youth to engage in critical hope to imagine a better, more just world.Originality/valueIn a time when young Latinx students are continually subjected to racism and xenophobia promoted by political figures and taken up by popular media and the general public, it is necessary to support students in creating counter-stories and critical hope that push back against oppression. Findings suggest that the superhero genre can support Latinx students to discuss, dismantle and counter hateful discourses while striving for hope.
Influence of selected parameters on phenomena of two-phase flow and heat exchange in TSL furnace – numerical investigation
Authors: Kolczyk Ewa , Miczkowski Zdzisław , Czernecki Józef 
Published: October 2017

Purpose
The purpose of this study is application of a numerical simulation for determination of the influence of geometric parameters of a furnace and hydrodynamics of the gas introduced by a vertical submerged lance on the process of feed mixing and temperature distribution.

Design/methodology/approach
A numerical simulation with Phoenics software was applied for modeling of liquid phase movement and heat exchange between the gas supplied through a lance and the slag feed in a top submerged lance (TSL) furnace. The simulation of a two-phase flow of a slag–gas mixture based on the inter phase slip algorithm module was conducted. The influence of selected parameters, such as depth of lance submergence, gas flow rate and change of furnace geometry, on the phenomena of movement was studied.

Findings
Growth of dynamics of mixing with the depth of lance submergence and with increase of gas velocity in the lance was observed. Formation of a recirculation zone in the liquid slag was registered. Movement of the slag caused by the gas flow brought homogenization of the temperature field.

Originality/value
The study applied the simulation of a two-phase flow in the liquid slag–gas system in steady state, taking into account heat transfer between phases. It provides possibilities for optimization and selection of process parameters within the scope of the developed new technology using a TSL furnace.
Load balancing for chemically reacting flows
Authors: Löhner Rainald , Togashi Fumiya , Baum Joseph David 
Published: October 2017

Purpose
A common observation made when computing chemically reacting flows is how central processing unit (CPU)-intensive these are in comparison to cold flow cases. The update of tens or hundreds of species with hundreds or thousands of reactions can easily consume more than 95% of the total CPU time. In many cases, the region where reactions (combustion) are actually taking place comprises only a very small percentage of the volume. Typical examples are flame fronts propagating through a domain. In such cases, only a small fraction of points/cells needs a full chemistry update. This leads to extreme load imbalances on parallel machines. The purpose of the present work is to develop a methodology to balance the work in an optimal way.

Design/methodology/approach
Points that require a full chemistry update are identified, gathered and distributed across the network, so that work is evenly distributed. Once the chemistry has been updated, the unknowns are gathered back.

Findings
The procedure has been found to work extremely well, leading to optimal load balance with insignificant communication overheads.

Research limitations/implications
In many production runs, the procedure leads to a reduction in CPU requirements of more than an order of magnitude. This allows much larger and longer runs, improving accuracy and statistics.

Practical implications
The procedure has allowed the calculation of chemically reacting flow cases that were hitherto not possible.

Originality/value
To the authors’ knowledge, this type of load balancing has not been published before.
Unsteady natural convection with entropy generation in partially open triangular cavities with a local heat source
Authors: Öztop Hakan F. , Bondareva Nadezhda S. , Sheremet Mikhail A. , Abu-Hamdeh Nidal 
Published: October 2017

Purpose
The main aim of this work is to perform a numerical analysis on natural convection with entropy generation in a partially open triangular cavity with a local heat source.

Design/methodology/approach
The unsteady governing dimensionless partial differential equations with corresponding initially and boundary conditions were numerically solved by the finite difference method of the second-order accuracy. The effects of dimensionless time is studied, and other governing parameters are Rayleigh number (Ra = 103 − 105), Prandtl number (Pr = 6.82), heater length (w/L = 0.2, 0.4 and 0.6) and distance of heater ratio (δ/L = 0.3).

Findings
An increase in the Rayleigh number leads to an increment of the fluid flow and heat transfer rates. Average Bejan number decreases with Ra as opposed to the average Nusselt number and average entropy generation. High values of Ra characterize a formation of long-duration oscillating behavior for the average Nusselt number and entropy generation.

Originality/value
The originality of this work is to analyze the entropy generation in natural convection in a one side open and partial heater-located cavity. This is a good application for electronical systems or building design.
Exploring the influence of store attributes on customer experience and customer engagement
Authors: Mohd-Ramly Suhaily , Omar Nor Asiah 
Published: October 2017

Purpose
The global retail landscape has changed drastically. The rising role of Asia as one of the fastest growing international retail penetration and expansion will continue to make the region to be the driving force in world economic growth. However, the ambitious expansion plans are making the retail sector to be more challenging. Emphasizing on the customer experience and enhancing the value proposition to customers are undeniably vital factors for the long-term survival of any retail business. Therefore, the purpose of this paper is to examine the influence of store attributes on customer experience and customer engagement in the context of department store in Malaysia. Subsequently, the influence of customer experience on customer engagement is also analyzed.

Design/methodology/approach
Using drop and collect survey, 484 valid responses of department store cardholders of age 18 years and above in the area Klang Valley, Malaysia, were collected. PLS structural equation modeling was used to test the hypotheses of this study.

Findings
Results revealed that customer experience is influenced by merchandise, store atmosphere, and loyalty program, while customer engagement is influenced by merchandise, communication, interpersonal communication, and loyalty. In contrast, post-transaction services were found to have non-significant impact on both customer experience and customer engagement. Analysis also revealed a strong relationship between customer experience and customer engagement.

Research limitations/implications
This study is carried out on customers of department store in Malaysia. However, the researchers urge other researchers to replicate the study from different countries and category of department stores.

Originality/value
Retail researchers recognize little knowledge on the contribution of store attributes to customer experience and customer engagement. This paper represents original research that encourages foreign retailers to employ service-dominant logic as a new marketing thought in designing strong customer engagement and experience strategies to capture the Malaysia market.
Truckies and health promotion: using the ANGELO framework to understand the workplace’s role
Authors: Sendall Marguerite C. , Crane Phil , McCosker Laura , Fleming Marylou , Biggs Herbert C. , Rowland Bevan 
Published: October 2017

Purpose
Workplaces are challenging environments which place workers at the risk of obesity. This is particularly true for Australian road transport industry workplaces. The Analysis Grid for Environments Linked to Obesity (ANGELO) framework is a public health tool which can be used to conceptualise obesogenic environments. It suggests that workplaces have a variety of roles (in the physical, economic, political and sociocultural domains) in responding to obesity in transport industry workplaces. The purpose of this paper is to present the findings which explore this idea.

Design/methodology/approach
The project used a mixed-methods approach located within a participatory action research framework, to engage workplace managers and truck drivers in the implementation and evaluation of workplace health promotion strategies. The project involved six transport industry workplaces in Queensland, Australia.

Findings
This study found that transport industry workplaces perceive themselves to have an important role in addressing the physical, economic, political and sociocultural aspects of obesity, as per the ANGELO framework. However, transport industry employees – specifically, truck drivers – do not perceive workplaces to have a major role in health; rather, they consider health to be an area of personal responsibility.

Practical implications
Balancing the competing perceptions of truck drivers and workplace managers about the workplace’s role in health promotion is an important consideration for future health promotion activities in this hard-to-reach, at-risk population.

Originality/value
The use of the ANGELO framework allows the conceptualisation of obesity in a novel workplace context.
Heterogeneous expression of glycoconjugates in the primary olfactory centre of the Japanese sword‐tailed newt (Cynops ensicauda)
Authors: Matsui T. , Tanaka K. , Kobayashi Y. 
Published: October 2017

SummaryHistochemical organization of the Caudata olfactory system remains largely unknown, despite this amphibian order showing phylogenetic diversity in the development of the vomeronasal organ and its primary centre, the accessory olfactory bulb. Here, we investigated the glycoconjugate distribution in the olfactory bulb of a semi‐aquatic salamander, the Japanese sword‐tailed newt (Cynops ensicauda), by histochemical analysis of the lectins that were present. Eleven lectins showed a specific binding to the olfactory and vomeronasal nerves as well as to the olfactory glomeruli. Among them, succinylated wheat germ agglutinin (s‐WGA), soya bean agglutinin (SBA), Bandeiraea simplicifolia lectin‐I (BSL‐I) and peanut agglutinin showed significantly different bindings to glomeruli between the main and accessory olfactory bulbs. We also found that s‐WGA, SBA, BSL‐I and Pisum sativum agglutinin preferentially bound to a rostral cluster of glomeruli in the main olfactory bulb. This finding suggests the presence of a functional subset of primary projections to the main olfactory system. Our results therefore demonstrated a region‐specific glycoconjugate expression in the olfactory bulb of C. ensicauda, which would be related to a functional segregation of the olfactory system.
Peripheral nerve block in ankle fracture surgery: a qualitative study of patients’ experiences
Authors: Henningsen M. J. , Sort R. , Møller A. M. , Herling S. F. 
Published: October 2017

SummaryPeripheral nerve blocks are popular as a mode of anaesthesia for limb surgery and their beneficial effects are well documented in elective surgery. However, concerns have been raised about potential rebound pain outweighing the benefits in acute ankle fracture surgery. Furthermore, pain scores and morphine consumption do not provide a full picture, as pain is subjective. To evaluate the clinical usefulness of peripheral nerve blocks, we explored patients’ expectations and experiences by means of semi‐structured interviews analysed with systematic text condensation. We obtained ethical approval and informed consent and sampled purposively among adult patients scheduled for ankle surgery with nerve blocks as the primary mode of anaesthesia. Patients were interviewed within 48 h postoperatively. Data saturation was reached after 13 interviews. We found that, despite pre‐emptive ibuprofen and paracetamol, some patients did experience excruciating rebound pain for up to 2 h, although most had little or no pain. The patients had doubts about what to do when the block wore off, which led to a risk of unnecessary pain levels or morphine overuse. Patients had difficulty understanding the effect and course of the nerve blocks. They had misunderstandings regarding the blocks’ effect on sensation, resulting in fear of feeling pain during surgery and of permanent nerve damage after surgery. However, patients valued the mental alertness, ability to ambulate and efficient pain relief provided by the blocks. We recommend that patients be given thorough and repeated information as we feel this is crucial in preventing undesirable responses from patients, and is likely to increase the overall clinical usefulness of nerve blocks in acute limb surgery.
Radiographic and clinical outcomes of rooted, platform‐switched, microthreaded implants with a sandblasted, large‐grid, and acid‐etched surface: A 5‐year prospective study
Authors: Mei Dong Mei , Zhao Baodong , Xu Hao , Wang Yanhui 
Published: October 2017

AbstractBackgroundThere is no data available on the long‐term outcomes of a rooted, platform‐switched, microthreaded implant with a sandblasted, large‐grid, and acid‐etched surface.PurposeThis prospective, longitudinal study evaluated the clinical and radiographic outcomes of rooted, platform‐switched, microthreaded and sandblasted, large‐grid, and acid‐etched (SLA) surface implants for 5 years.Materials and MethodsSixty implants were placed in sixty patients with partially edentulous maxillae or mandibles. The permanent prostheses were inserted 2–4 months after implant placement. Clinical and radiographic examinations were performed at follow‐up visits scheduled postoperation, prosthesis installation, 1 year, and 5 years after surgery, to assess implant survival and success rates, biological and mechanical complications, and marginal bone loss.ResultsAfter 5 years’ follow‐up, four patients withdrawn from the study, and 56 implants achieved a 100% survival rate and 98.2% success rate. Three prosthetic complications occurred, resulting in a success rate for prostheses of 94.6%. The incidence of peri‐implant mucositis was 9.1% and no peri‐implantitis was diagnosed. The average marginal bone loss at the mesial aspect was 0.46 ± 0.27 mm after 1 year and 0.48 ± 0.27 mm after 5 years. The average marginal bone loss at the distal aspect was 0.46 ± 0.32 mm after 1 year and 0.50 ± 0.35 mm after 5 years.ConclusionAfter 5 years of loading, the rooted, platform‐switched, microthreaded, and SLA surface implants showed high survival and success rates, steady crestal bone levels, and excellent long‐term clinical outcomes in the soft tissue. Overloading may be related to the marginal bone loss around implants, but the surgical protocol, different sites, and jaw position did not correlate with crestal bone loss.
Real Objects Can Impede Conditional Reasoning but Augmented Objects Do Not
Authors: Sato Yuri , Sugimoto Yutaro , Ueda Kazuhiro 
Published: October 2017

AbstractIn this study, Knauff and Johnson‐Laird's (2002) visual impedance hypothesis (i.e., mental representations with irrelevant visual detail can impede reasoning) is applied to the domain of external representations and diagrammatic reasoning. We show that the use of real objects and augmented real (AR) objects can control human interpretation and reasoning about conditionals. As participants made inferences (e.g., an invalid one from "if P then Q" to "P"), they also moved objects corresponding to premises. Participants who moved real objects made more invalid inferences than those who moved AR objects and those who did not manipulate objects (there was no significant difference between the last two groups). Our results showed that real objects impeded conditional reasoning, but AR objects did not. These findings are explained by the fact that real objects may over‐specify a single state that exists, while AR objects suggest multiple possibilities.

Authors: de Waal Alexandra , Dixon Lisa B. , Humensky Jennifer L. 
Published: October 2017

AimTo explore baseline ratings of importance (ROI) across life domains for participants in the Recovery After an Initial Schizophrenia Episode Connection Program (RAISE CP), and investigate whether ratings were correlated with intervention outcomes over time.MethodsAt baseline, 63 participants rated the importance of reducing symptoms, side‐effects, confusion, increasing energy and school/work functioning and improving social relations. ROIs were examined in relation to work/school participation (n = 41) and occupational functioning (n = 37) after 12 months. Participants’ mean age was 22.3 (±4.2).ResultsThe ROI domain rated as most important was school/work functioning, and higher school/work ROI at baseline predicted work/school participation after 12 months of participation.ConclusionsIt is particularly important to assess participant preferences and priorities when treating psychotic disorders because most areas of life are affected. Understanding the impact of participant goals on outcomes is essential as programs design patient‐centred treatment plans.
Benefits of and Barriers to Romantic Relationships Among Mothers in Ireland
Authors: Hadfield Kristin , Nixon Elizabeth 
Published: October 2017

ObjectiveTo examine what mothers expect of their romantic relationships and what prevents them from forming and maintaining relationships.BackgroundAlthough there has been research on mothers' attitudes toward and expectations of marriage, there has been limited examination of their dating. It is critical to understand why parents form romantic relationships and what might cause them to cycle in and out of relationships to understand stepfamily formation.MethodOn the basis of semistructured interviews with a convenience sample of 33 single or repartnered Irish mothers, we conducted a thematic analysis guided by a social exchange framework.ResultsMothers believed that being in a relationship would enable them to enact their preferred relationship roles, give them extra support, and provide a different gender role model for their child(ren). They found forming long‐term relationships difficult because of a lack of suitable partners, limited time and support, stepparents' possible negative influences on their child(ren), and their own personal characteristics. Unlike previous studies conducted in the United States, Irish mothers were not focused on the economic viability of partners or on economic benefits associated with repartnering.ConclusionsMothers believe that there are several rewards to forming and being in a relationship, but they face many impediments that may prevent them from forming long‐term relationships.ImplicationsPractitioners may find it useful to focus on tempering mothers' expectations of relationship benefits and on reducing mothers' personal costs when forming and maintaining relationships.
International volunteering in a changing aidland
Authors: Schech Susanne 
Published: October 2017

AbstractThe growing diversity of North – South international volunteerism challenges the widely accepted distinction between volunteering for development as a long‐standing component of official development assistance and the more recent phenomenon of volunteer tourism as a private sector led commercial endeavour focused primarily on the personal growth of the volunteer. This paper reviews recent research that blurs this distinction by placing international volunteering within the geographical imaginaries of development and the neoliberal practices of governance of aidland. It focuses on four themes tackled in recent research: i) the ways in which neoliberal ideologies have shaped the motivations, goals, practices and governance of international volunteering; ii) the contexts in which international volunteering can foster more equitable relationships between Northern and Southern development actors; iii) what roles emotion and affect play in these relationships, and iv) the extent to which international volunteering can offer a critical perspective on the rules, logics and ideologies of aidland. The main argument is that while neoliberal conceptualisations of development have evidently shaped international volunteering, they do not fully capture the relational and experiential impacts of volunteering. The technologies of proximity afforded by volunteering can lead to critical and transformative insights into development and aidland, particularly when volunteers are embedded in local organisations over a longer time.

Published: October 2017

AbstractThe purpose of this study was to investigate incidence rates and levels of microbial contamination in open‐but‐unused portions of wound dressings stored in home settings. Portions of wound dressings were collected at up to four home visits for 104 clients undertaking wound management within their home. A control sample and stored sample was collected on each home visit and sent for pathology testing to identify levels of microbial contamination. The stored open‐but‐unused wound dressings were managed according to a written protocol. Of the tested samples (n = 776), 6% of control samples and 7% of test samples had microbial contamination. From regression analysis, the stored samples were more likely to have microbial contamination than control samples, but results were not statistically significant. In comparing occasions of storage and handling across four home visits, after adjusting for sample group and dressing type, none of the home visit occasion regressions were statistically significant. In conclusion, storage of open‐but‐unused portions of wound dressings kept in home settings does not appear to increase the rate of microbial contamination compared to newly opened wound dressings.
