Key determinants of waste separation intention: empirical application of TPB
Authors: Ayob Siti Fadzilah , Sheau-Ting Low , Abdul Jalil Rohaya , Chin Hon-Choong 
Published: July 2017

Purpose
This study aims to identify the key determinants of waste separation intention among the students in Universiti Teknologi Malaysia (UTM).

Design/methodology/approach
This study adopted the theory of planned behaviour (TPB) as the fundamental framework. The key determinants of waste separation behaviour are attitude, subjective norm (SN) and perceived behavioural control. An elicitation survey has been conducted to explore the students’ beliefs relative to waste separation behaviour. The empirical data collected were analysed using structural equation modelling (SEM) assisted by SmartPLS software.

Findings
The result shows that only two determinants are significant towards intention, attitude and perceived behavioural control, while SN is not. The results of the study are significant to the organisation, as an identification of the determinants that influence waste separation intention contributes to a more focused waste separation programme aligned to Malaysia’s objective towards a sustainable developing country.

Originality/value
There are few studies on solid waste separation compared to food waste and industrial waste separation. The authors focus on the identification of the key determinants of solid waste separation intention among students. This study serves as an initial attempt to adopt the TPB in solid waste separation context, hence contributing to existing literature.
A decision support system for retail assortment planning
Authors: Hübner Alexander 
Published: July 2017

Purpose
Because increasing product variety in retail conflicts with limited shelf space, managing assortment and shelf quantities is a core decision in this sector. A retailer needs to define the assortment size and then assign shelf space to meet consumer demand. However, the current literature lacks not only information on the comprehensive structure of the decision problem, but also a decision support system that can be directly applied to practice in a straightforward manner. The paper aims to discuss these issues.

Design/methodology/approach
The findings were developed and evaluated by means of explorative interviews with grocery retail experts. An optimization model is proposed to solve the problem of assortment planning with limited shelf space for data sets of a size relevant in real retail practice.

Findings
The author identifies the underlying planning problems based on a qualitative survey of retailers and relates the problems to each other. This paper develops a pragmatic approach to the capacitated assortment problem with stochastic demand and substitution effects. The numerical examples reveal that substitution demand has a significant impact on total profit and solution structure.

Practical implications
The author shows that the model and solution approach are scalable to problem sizes relevant in practice. Furthermore, the planning architecture structures the related planning questions and forms a foundation for further research on decision support systems.

Originality/value
The planning framework structures the associated decision problems in assortment planning. An efficient solution approach for assortment planning is proposed.

Authors: Chen Yan , Chen Wenzhuo , Li Bo , Zhang Gang , Zhang Weiming 
Published: July 2017

Purpose
The purposes of this paper are to review the progress of and conclude the trend for paint thickness simulation for painting robot trajectory planning.

Design/methodology/approach
This paper compares the explicit function-based method and computational fluid dynamics (CFD)-based method used for paint thickness simulation. Previous research is considered, and conclusions with the outlook are drawn.

Findings
The CFD-based paint deposition simulation is the trend for paint thickness simulation for painting robot trajectory planning. However, the calculation of paint thickness resulting from dynamically painting complex surface remains to be researched, which needs to build an appropriate CFD model, study approaches to dynamic painting simulation and investigate the simulation with continuously changing painting parameters.

Originality/value
This paper illustrates that the CFD-based method is the trend for the paint thickness simulation for painting robot trajectory planning. Current studies have been analyzed, and techniques of CFD modeling have also been summarized, which is vital for future study.
Peg-In-Hole search using convex optimization techniques
Authors: Sharma Kamal , Shirwalkar Varsha , Pal Prabir K. 
Published: July 2017

Purpose
This paper aims to provide a solution to the first phase of a force-controlled circular Peg-In-Hole assembly using an industrial robot. The paper suggests motion planning of the robot’s end-effector so as to perform Peg-In-Hole search with minimum a priori information of the working environment.

Design/methodology/approach
The paper models Peg-In-Hole search problem as a problem of finding the minima in depth profile for a particular assembly. Thereafter, various optimization techniques are used to guide the robot to locate minima and complete the hole search. This approach is inspired by a human’s approach of searching a hole by moving peg in various directions so as to search a point of maximum insertion which is same as the minima in depth profile.

Findings
The usage of optimization techniques for hole search allows the robot to work with minimum a priori information of the working environment. Also, the iterative nature of the techniques adapts to any disturbance during assembly.

Practical implications
The techniques discussed here are quite useful if a force-controlled assembly needs to be performed in a highly unknown environment and also when the assembly setup can get disturbed in between.

Originality/value
The concept is original and provides a non-conventional use of optimization techniques, not for optimization of some process directly but for an industrial robot’s motion planning.
Developing an empirical typology of diversity-oriented human resource management practices
Authors: Meena Kavita , Vanka Sita 
Published: July 2017

PurposeThe significance of human resource management in managing workforce diversity has been emphasized by researchers and various practices have been identified and prescribed in literature. However, there is lack of HR typologies to understand different diversity management alternatives. Hence, the purpose of this paper is to develop a typology of diversity-oriented human resource management (DHRM) practices for clear understanding.Design/methodology/approachThe study employs factor analysis approach for developing typology. In total, 31 human resource management practices covering the five functions of HR, i.e. recruitment, selection, performance evaluation, compensation and training were identified from literature. These practices were analyzed to investigate whether and how these 31 practices cluster into higher order DHRM practices categories.FindingsFrom factor analysis, seven categories of DHRM practices emerged. The findings showed marked differences in these seven DHRM practices categories aimed at managing diversity.Research limitations/implicationsFuture, survey researchers can use this typology of DHRM practices to design instruments that allow a more in-depth and differentiating analysis of role of HRM in managing diversity than those that have been carried out in previous research.Practical implicationsManagers can use the seven types of DHRM practices identified as criteria to choose an adequate pattern for HRM practices to manage diversity.Originality/valueThe typology developed in the study has foundations in specific diversity-related HRM practices rather than based on generic HRM typologies.
From request to assess: using cloud-based tools for the library instruction lifecycle
Authors: Parrigin James 
Published: July 2017

Purpose
The author first gained experience with library instruction scheduling at a large research university library as an Master of Library and Information Science (MLIS) graduate assistant.

Design/methodology/approach
The author would occasionally shadow the faculty librarians as they received instruction requests, which were vetted by an administrative assistant and entered into some mystical technology that would facilitate the reservations and populate a library staff calendar.

Findings
The author remembers it as a fairly mundane process that he did not think much of at the time.

Social implications
The author soon became an instruction librarian who was put in charge of orchestrating the multitudes of course-integrated one-shots at a small, private four-year liberal arts college.

Originality/value
The author thinks back to this experience and marvels at the humble instructional requests (e.g. “just show them JSTOR”) and the primitive tool that their library used for scheduling their sessions: a spreadsheet on our network drive.
Predator exposure improves anti‐predator responses in a threatened mammal

Published: July 2017

Abstract

Incorporating an understanding of animal behaviour into conservation programmes can influence conservation outcomes. Exotic predators can have devastating impacts on native prey species and thwart reintroduction efforts, in part due to prey naïveté caused by an absence of co‐evolution between predators and prey. Attempts have been made to improve the anti‐predator behaviours of reintroduced native prey by conducting laboratory‐based predator recognition training but results have been varied and have rarely led to improved survival in reintroduction programmes.

We investigated whether in situ predator exposure could improve anti‐predator responses of a predator‐naïve mammal by exposing prey populations to low densities of introduced predators under controlled conditions. We reintroduced 352 burrowing bettongs to a 26‐km2 fenced exclosure at the Arid Recovery Reserve in South Australia and exposed them to feral cats (density 0.03–0.15 cats/km2) over an 18‐month period. At the same time, we translocated a different group of bettongs into an exclosure free of introduced predators, as a control. We compared three behaviours (flight initiation distances, trap docility and behaviour at feeding trays) of cat‐exposed and control bettongs before the translocations, then at 6, 12 and 18 months post‐translocation.

Cat‐exposed bettongs displayed changes in behaviour that suggested increased wariness, relative to control bettongs. At 18 months post‐reintroduction, cat‐exposed bettongs had greater flight initiation distances and approached feed trays more slowly than control bettongs. Cat‐exposed bettongs also increased their trap docility over time.

Synthesis and applications. Translocation is recommended as a conservation tool for many threatened species yet success rates are generally low. We demonstrate that controlled levels of in situ predator exposure can increase wariness in the behaviour of naïve prey. Our findings provide support for the hypothesis that in situ predator exposure could be used as a method to improve the anti‐predator responses of predator‐naïve threatened species populations.

SummaryThe effects of hypertonic solution on airway smooth muscle (ASM) contraction and the underlying mechanisms are largely unknown. We found that hypertonic saline (HS) inhibited acetylcholine (ACh)‐induced contraction of ASM from the mouse trachea and human bronchi. In single mouse ASM cells (ASMCs), ACh induced an increase in intracellular Ca2+ that was further enhanced by 5% NaCl, indicating that the HS‐induced inhibition of ASM contraction was not mediated by a decrease in cytosolic Ca2+. The Rho‐associated kinase (ROCK) inhibitor Y‐27632 relaxed ACh‐induced precontraction of mouse tracheal rings. However, such inhibition was not observed after the relaxation induced by 5% NaCl. Moreover, the incubation of mouse tracheal rings with 5% NaCl decreased ACh‐induced phosphorylation of myosin light chain 20 and myosin phosphatase target subunit 1. These data indicate that HS inhibits the contraction of ASM by inhibiting Ca2+ sensitization, not by decreasing intracellular Ca2+.
Dominance‐function relationships in the amphibian skin microbiome
Authors: Walke Jenifer B. , Becker Matthew H. , Hughey Myra C. , Swartwout Meredith C. , Jensen Roderick V. , Belden Lisa K. 
Published: July 2017

SummarySome amphibian skin bacteria inhibit growth of a fungal amphibian pathogen, Batrachochytrium dendrobatidis (Bd), but it is unclear how dominant these anti‐Bd bacteria are in skin communities. Using in vitro co‐culture challenge assays, we quantified Bd inhibition by bacterial isolates collected from the skin of four amphibian species: bullfrogs, Eastern newts, spring peepers and American toads. The 16S rRNA sequences for each isolate were matched to culture‐independent amplicon sequences from the same individuals to assess inhibitory function versus relative abundance. Dominant bacteria had higher Bd inhibition than rare bacteria in bullfrog and newt populations, in which Bd was prevalent (> 25%). Dominant and rare bacteria did not differ in Bd inhibition in spring peeper and toad populations, in which Bd was absent or at low prevalence (< 7%). In addition, over half of the relative abundance of cultured bacteria on bullfrogs and newts was comprised of inhibitory bacteria, while only 25% and 37% of the relative abundance was inhibitory on spring peepers and toads, respectively. These results suggest that the dominant members of the amphibian skin bacterial community may be functionally important in terms of disease‐resistance, and that Bd prevalence and/or host species identity may impact the relative abundance and inhibitory properties of skin bacteria.

Published: July 2017

SummaryTn‐seq was used to identify genes essential for phototrophic growth by the purple bacterium Rhodopseudomonas palustris. About 167 genes required for anaerobic growth on acetate in light were identified, 35 of which are annotated as photosynthesis genes. The essentiality of many of these genes by analysing the phenotypes of independently generated mutants that had altered pigmentation was verified. Three genes were identified, two possibly involved in biogenesis of the membrane‐bound photosynthetic apparatus and one for phosphatidylcholine biosynthesis, that were not known to be essential for phototrophic growth. Site‐directed mutagenesis was used to show that the NADH:quinone oxidoreductase complex IE was essential for phototrophic growth under strictly anaerobic conditions and appeared to play a role in reverse electron transport to generate NADH. A homologous NADH:quinone oxidoreductase complex IA likely operates in the opposite direction to oxidize NADH. The operation of the two enzymes in opposition would allow R. palustris to maintain redox balance. As a complement to the genetic data, proteomics experiments were carried out in which it was found that 408 proteins were present in significantly higher amounts in cells grown anaerobically in light compared with aerobically. Among these were proteins encoded by subset of the phototrophic growth‐essential genes.

ObjectiveTo compare outcomes of patients with pure adenocarcinoma‐in‐situ (AIS) and mixed AIS/CIN 2/3 lesions including the incidence of AIS persistence, recurrence and progression to adenocarcinoma.DesignRetrospective cohort study.SettingStatewide population in Western Australia.PopulationWomen diagnosed with AIS between 2001 and 2012.MethodsWe conducted a retrospective, population‐based cohort study.Main outcome measuresDe‐identified linked data were utilised to ascertain the association between patient age at excisional treatment, margin status, lesion type, lesion size, and risk of persistent AIS (defined as the presence of AIS <12 months from treatment), recurrent AIS (≥12 months post‐treatment), and adenocarcinoma.Results636 patients were eligible for analysis. The mean age was 32.3 years and median follow‐up interval was 2.5 years. Within the study cohort, 266 patients (41.8%) had pure AIS and 370 (58.2%) had mixed AIS/CIN 2/3. Overall, 47 patients (7.4%) had AIS persistence/recurrence and 12 (1.9%) had adenocarcinoma. Factors associated with persistence/recurrence were pure AIS (hazard ratio (HR) 2.3; 95%CI 1.28–3.94; P = 0.005), age >30 years (HR 2.1; 95%CI 1.16–3.81; P = 0.015), positive endocervical margins (HR 5.8; 95%CI 3.05–10.92; P = <0.001) and AIS lesions >8 mm (HR 2.5; 95%CI 1.00–6.20; P = 0.049). A histologically positive AIS ectocervical margin was not associated with persistence/recurrence.ConclusionIn this study, pure AIS was associated with greater risk of persistence/recurrence than was mixed AIS/CIN 2/3. AIS lesions >8 mm and positive endocervical margins were significant predictors for persistent or recurrent disease.Tweetable AbstractPure cervical adenocarcinoma‐in‐situ (AIS) may have greater risk of recurrence than AIS co‐existing with CIN 2/3.
At‐Risk Alcohol Use is Associated with Antiretroviral Treatment Nonadherence Among Adults Living with HIV/AIDS

Published: July 2017

BackgroundAlcohol use is a risk factor for nonadherence to antiretroviral therapy (ART) among people living with HIV/AIDS (PLWHA); however, differences in ART adherence across levels of alcohol use are unclear. This study examined whether “at‐risk” alcohol use, defined by National Institute of Alcohol Abuse and Alcoholism guidelines, was associated with ART nonadherence among PLWHA.MethodsParticipants were 535 HIV‐infected adults enrolled in studies at the HIV Neurobehavioral Research Program. ART nonadherence was identified by either self‐reported missed dose or plasma viral load detectability (≥50 copies/ml). Potential covariates for multivariable logistic regression included demographics, depression, and substance use disorders.ResultsUsing a stepwise model selection procedure, we found that at‐risk alcohol use (OR = 0.64; p = 0.032) and low education (OR = 1.09 per 1 year increase in education; p = 0.009) significantly predict lower ART adherence.ConclusionsA greater focus on the treatment of at‐risk alcohol use may improve ART adherence among HIV‐infected persons.
A new generation of mTORC1 inhibitor attenuates alcohol intake and reward in mice

Published: July 2017

AbstractAlcohol use disorder (AUD) is a chronic condition associated with devastating socioeconomic consequences. Yet, pharmacotherapies to treat behavioral phenotypes such as uncontrolled heavy drinking are limited. Studies in rodents suggest that the mammalian target of rapamycin complex 1 (mTORC1) plays an important role in mechanisms underlying alcohol drinking behaviors as well as alcohol seeking and relapse. These preclinical evidence suggest that mTORC1 may be a therapeutic target for the treatment of AUD. Thus, the aim of the present study was to test the potential use of newly developed mTORC1 inhibitors, RapaLink‐1 and MLN0128, in preclinical mouse models of AUD. First, we used the intermittent access to 20 percent alcohol in a two‐bottle choice paradigm and tested the efficacy of the drugs to reduce alcohol intake in mice with a history of binge drinking and withdrawal. We found that both inhibitors reduce excessive alcohol intake and preference with RapaLink‐1 exhibiting higher efficacy. We further observed that RapaLink‐1 attenuates alcohol consumption during the first alcohol‐drinking session in naïve mice, and interestingly, the effect was still present 14 days after the initial treatment with the drug. We also found that RapaLink‐1 did not alter the consumption of water or saccharin, revealing a specific effect of the inhibitor on alcohol intake. Finally, we report that RapaLink‐1 blocks the retrieval but not acquisition of alcohol place preference without affecting locomotion. Together, our findings suggest that RapaLink‐1 may be developed as a new medication to treat and prevent the development of AUD.

ABSTRACTFor many Indigenous peoples, their traditional lands are archives of their histories, from the deepest of time to recent memories and actions. These histories are written in the landscapes’ geological features, contemporary plant and animal communities, and associated archaeological and paleoecological records. Some of these landscapes, recently termed “cultural keystone places” (CKPs), are iconic for these groups and have become symbols of the connections between the past and the future, and between people and place. Using an historical‐ecological approach, we describe our novel methods and initial results for documenting the history of three cultural keystone places in coastal British Columbia, Canada: Hauyat, Laxgalts'ap (Old Town) and Dałk Gyilakyaw (Robin Town) (territories of Heiltsuk, Gitga'ata, and Gitsm'geelm, respectively). We combine data and knowledge from diverse disciplines and communities to tell the deep and recent histories of these cultural landscapes. Each of CKPs encompasses expansive landscapes of diverse habitats transformed by generations of people interacting with their surrounding environments. Documenting the “softer” footprints of past human‐environmental interactions can be elusive and requires diverse approaches and novel techniques.
