Authors: Klinger Cristiano Pinto , Silveira-Martins Elvis , Castro Gabriela Jurak de , Rossetto Carlos Ricardo 
Published: December 2019

PurposeThe purpose of this study is to verify whether managers’ strategic orientation influences decision-making related to differentiation and whether these two factors impact on the performance of the firms in the Brazilian wine industry.Design/methodology/approachA survey was conducted with representatives from 123 wineries located in the following Brazilian states: 78.86 per cent in Rio Grande do Sul; 13.01 per cent in Santa Catarina; 2.44 per cent in Paraná; 2.44 per cent in São Paulo; 1.63 per cent in Bahia; and 1.63 per cent in Pernambuco. The data were analyzed using multivariate statistical techniques, resulting in a structural equations model of the constructs.FindingsThe research findings show that there is a positive association between prospector orientation and differentiation. Analyst positioning was negatively associated with differentiation of winery companies. It was also possible to show that differentiation has a positive relationship with performance.Originality/valueWhile a previous study attempted to identify wineries’ strategic orientation using other theoretical constructs, this study makes a contribution to consolidating reflections on strategic orientation focused on differentiation and performance. The results contribute to expanding the scientific debate by filling a gap in existing theory and also provide information of use to decision-makers, demonstrating, which approaches improve differentiation, and hence, performance.
Interventions as the centrepiece of psychosocial risk assessment – why so difficult?
Authors: Schuller Katja 
Published: December 2019

PurposeDue to the “European Union Framework Directive on Safety and Health at work” (Directive 89/391/EEC, 1989), every employer is obliged to avoid psychosocial hazards when designing work. Little is known empirically about the barriers that workplace actors experience while developing and implementing OSH measures that prevent psychosocial hazards. The purpose of this paper is to explore barriers, causes and attempts to overcome them and discusses them with reference to relevant theoretical concepts and models that help to explain how these barriers hinder the development and implementation of OSH measures.Design/methodology/approachSemi-structured interviews with workplace actors in charge of psychosocial risk assessment (PRA) were conducted in 41 business cases, and transcripts were analysed using a thematic analysis approach. Barriers, causes and attempts to overcome them were extracted inductively and discussed with reference to relevant theories and explanatory models.FindingsThe complex nature of psychosocial risks, hindering general beliefs, lack of a perceived scope for risk avoidance, lack of assumptions of responsibility among players on all hierarchical levels, discrepancies between formal responsibility and decision authority, and low reflexivity on processes of development and implementation of interventions were described as barriers. Causes and attempts to overcome these barriers were reflected upon by workplace actors.Practical implicationsRecommendations on the organisation of PRA will be given with respect to the reported results and relevant research in this field.Originality/valueThis qualitative study explores the barriers to developing and implementing OSH measures to eliminate psychosocial hazards, from the perspective of actors in charge of PRA, and why they might fail.

Authors: Alphonce Swiga , Mwantimwa Kelefa 
Published: December 2019

Purpose
With the advent of ICTs, a large percentage of university students are shifting their interest and focus on digital learning resources from print ones. This study aims to examine the diversity, motivations and challenges students face in using these learning resources at Teofilo Kisanji University (TEKU) in Tanzania.

Design/methodology/approach
The researchers used elements of both quantitative and qualitative research approaches in a complementary fashion. The study draws upon cross-section survey data collected from students (n = 90) alongside follow-up key informants semi-structured interviews with library and academic staff (n = 10).

Findings
The study’s findings signify that internet resources are significantly deployed by students than other resources such as CD-ROM, e-books, journals, slides and audio clips. The findings further inform that the wide range of these resources and 24/7 convenient access are important motivating factors for their usage. On the other hand, the cost of internet services, limited searching competencies and limited subscribed databases inhibit effective and efficient usage of these by students at TEKU.

Originality/value
The present study clearly discloses students’ motivations for accessing and using digital learning resources.
Yard and berth planning efficiency with estimated handling time
Authors: Nishimura Etsuko 
Published: December 2019

Purpose
To achieve a high container handling efficiency at transshipment hub ports, there are a variety of scheduling problem as ship-to-berth assignment (BAP), container-to-yard arrangement (YAP), etc. As it is difficult to acquire the actual data of an existing terminal under various circumstances, this study aims to develop the time estimation model of container handling. Additionally, to achieve an efficient handling of containers at the yard, this study proposes the way to optimize the yard arrangement along with the berth allocation simultaneously by using estimated handling time.

Design/methodology/approach
To obtain the handling time based on various situations of the terminal operated, the discrete simulation model of container handling is constructed. The model to estimate the handling time of a quay crane assigned to a relevant ship by multiple regression analysis is developed. To find a feasible solution to minimize the total service time which includes YAP and BAP simultaneously, a genetic algorithm based on heuristics is developed.

Findings
The proposed regression model has high performance to estimate the time spent of container handling. In the total service time, the proposed approach outperformed the existing 2-step process approach.

Originality/value
As it is difficult to acquire the actual information of an existing marine terminal under various circumstances, the paper contains a regression model to estimate the container handling time based on simulation data, and the regression model is used in an optimization model to minimize the ship turnaround time.
Most appropriate time for the adaptive reuse of historic buildings using ARP model
Authors: Sharifi Ali 
Published: December 2019

Purpose
The concept of adaptive reuse is an effective strategy for enhancing heritage assets, economic, cultural and social values. The purpose of this paper is to propose a method to reuse historic buildings within appropriate time frames. The adaptive reuse potential (ARP) model assesses the potential of buildings based on obsolescence criteria in order to determine the optimal time for changing the use of such assets.

Design/methodology/approach
Both quantitative and qualitative methods have been used in this research to evaluate the reuse potential of The Mashrooteh Building by using the ARP model. Predicting and evaluating the physical life, useful life and potential of the historic Mashrooteh building in Tabriz will ensure its reuse and will increase its future life.

Findings
Findings have shown that to increase the future life of The Mashrooteh Building, its adaptive reuse quality needs to be improved for the next intervention within a reasonable time. Further procedures can be outlined when the appropriate time for future rehabilitation is known.

Originality/value
With an emphasis on conservation of national heritage as well as promoting sustainable development, the overall future life of assets can be extended. The significance of this study is closely related to organizations dealing with the conservation and rehabilitation of historical buildings with the emphasis on sustainable improvement of environmental, economic, social and functional aspects in the best possible time frame. The result of this study will add a value to existing sustainable reuse database in Tabriz and other countries in the Middle East region.
An evaluation model for an effective risk assessment in the rent to buy property market
Authors: Tajani Francesco , Morano Pierluigi , Salvo Francesca , De Ruggiero Manuela 
Published: December 2019

PurposeIn this research a model for the rationalization of the assessment in a rent to buy contract has been proposed, in order to contextualize the economic amounts involved in the negotiation according to the specific market risk of the area where the property is located. The paper aims to discuss this issue.Design/methodology/approachThe model borrows the logical principles of operational research, in order to take into account the convenience constraints of the parties involved (seller and buyer) and to determine the minimum amount of the additional annual rent to be charged as down payment on the final sale price, compensating the investment risk. The procedure proposed for the risk assessment combines the discrete modeling of real option analysis and the exponentially weighted moving average method, in order to weigh appropriately the data available for the specific area in the analysis.FindingsConsidering the limit conditions of variability of the property market value at the time provided for the notarial deed, the proposed model returns two values (minimum and maximum) for a fixed contract duration and for a specific market area for the annual additional rent, which define the reference range to ensure the compliance with the convenience constraints of the parties involved.Practical implicationsIn order to test the reliability of the developed methodology, the model has been implemented to the 24 “microzones” defined by the Italian Revenue Agency for the city of Bari (Southern Italy). The results obtained were then georeferenced, in order to create thematic maps of convenience for the subjects interested in the rent to buy formula. The developed maps define a useful support to be consulted in the negotiation phase between the seller and the buyer, allowing both to verify the investment conveniences within the limits of their disposable incomes and their needs.Originality/valueThe tabulated values of the down-payment amounts and the related thematic maps constitute a valid support for both the parties in the initial negotiation phase of the contractual conditions: in fact, if comparable data for the assessment of the market value and the market rent at the time of the stipulation of the contract are ordinarily available, the increase in the rent, to be charged as the annual down payment on the final purchase price, is generally entrusted to the contractual capabilities of the subjects involved, since there is no market reference that can direct an appropriate assessment.
Perceived environment of ethnic diversity as a determinant of organisational identification in the public sector
Authors: Pepple Dennis Gabriel , Davies Eleanor 
Published: December 2019

PurposeAs public sector managers implement the policy of employing people that broadly reflects the social make up of a local society, there is a need to ensure that employees have a positive perception of ethnic diversity. Perceived environment of ethnic diversity (PEED) is conceptualised as employees’ view of how they are treated at work irrespective of where they come from. The purpose of this paper is to investigate the relationship between PEED and organisational identification (OID).Design/methodology/approachData were collected by means of a survey of 908 employees from four public sector organisations in a state in Nigeria. Regression analysis was used to test the hypotheses.FindingsFindings showed that OID may be fostered among multi-ethnic employees through the following framework: first, PEED had a direct relationship with OID and support was found, which was explained by the mediating role of co-worker social support (CWSS). Second, the effect of CWSS mediation was moderated by employees’ ethnic self-identification (ESI) such that those with strong ESI experienced lower OID.Practical implicationsAs employee compositions in organisations increase in diversity, CWSS is presented in this study as a veritable measure for managers to foster OID.Originality/valueThis study is novel as it is one of the first to examine the mechanisms for linking PEED to OID through mediating effect of CWSS at different levels of ESI. Other contributions are discussed in detail in the study.

Published: December 2019

AbstractEnterovirus 71 (EV71) is the predominant pathogen for severe hand, foot, and mouth disease (HFMD) in children younger than 5 years, and currently no effective drugs are available for EV71. Thus, there is an urgent need to develop new drugs for the control of EV71 infection. In this study, LJ04 was extracted fromLaminaria japonicausing diethylaminoethyl cellulose‐52 with 0.4 mol/l NaCl as the eluent, and its virucidal activity was evaluated based on its cytopathic effects on a microplate. LJ04 is composed of fucose, galactose, and mannose and mainly showed good virucidal activity against EV71. The antiviral mechanisms of LJ04 were the direct inactivation of the virus, the blockage of virus binding, disruptions to viral entry, and weak inhibitory activity against the nonstructural protein 3C. The two most important findings from this study were that LJ04 inhibited EV71 proliferation in HM1900 cells, which are a human microglia cell line, and that LJ04 can directly inactivate EV71 within 2 hr at 37°C. This study demonstrates for the first time the ability of a polysaccharide fromL. japonicato inhibit viral and 3C activity; importantly, the inhibition of 3C might have a minor effect on the antiviral effect of LJ04. Consequently, our results identify LJ04 as a potential drug candidate for the control of severe EV71 infection in clinical settings.
Using limiting similarity to enhance invasion resistance: Theoretical and practical concerns
Authors: Hess Manon C. M. , Buisson Elise , Jaunatre Renaud , Mesléard François 
Published: December 2019

Abstract

The control of invasive species is a central topic of both applied and theoretical research. Understanding how and which ecological theories can be used to improve invasion resistance of plant communities is essential, to design effective control strategies.

The theory of limiting similarity, stating that coexistence between species is more limited by competitive exclusion when species share niche properties, is often considered by applied ecologists as a possible approach to limiting plant invasions at the local scale.

The complexity of measuring ecological niche overlap between species as well as the difficulty of disentangling niche from fitness processes currently limit the demonstration and application of this theory. Limiting similarity appears to operate at a time‐scale that is too long for efficient impact on invasive species' early establishment. It may also be ineffective against invasions in the long term, due to environmental changes and community instability. Finally, limiting similarity is not applicable to the most common situations, where there are multiple co‐occurring invasive species or no prior identification of potential invasives.

Synthesis and applications. Whether the theory of limiting similarity, predicting competitive exclusion when species display niche similarities, can be successfully applied to limit plant invasions—or not—is an important issue for practitioners facing invasive species. In practice, using limiting similarity to design invasion‐resistant plant communities appears to be complex, ineffective and unsuitable for most common situations.
Habitat fragmentation and eradication of invading insect herbivores

Abstract

Invasions by non‐native pests and diseases represent serious threats to biodiversity, agriculture and human health. Under current border arrival rates associated with international trade not all such invasions can be prevented, so early detection and eradication (forced extinction) are important strategies for preventing establishment and long‐term impacts. Removal of host plants has historically been a common tool used alone and in concert with other tools for eradication of plant pests but there is little scientific theory specific to the management of invasive species to guide the application of this eradication strategy.

We drew upon extensive conservation biology literature documenting the effect of habitat destruction or fragmentation driving extinction. We applied a previously developed spatially explicit model of gypsy moth, Lymantria dispar, spatial dynamics to explore how fragmentation affects population persistence. This model accounts for a component Allee effect driven by mate‐finding failure that interacts with dispersal.

We observed a nonlinear dependency of population persistence on the fraction of habitat cover and the level of habitat fragmentation. Simulation of active habitat fragmentation via the removal of habitat in swaths of varying widths or the application of pesticide in varying swaths showed that removal of hosts or pesticide application in narrow swaths (i.e. 40 m wide) caused the greatest probabilities of extinction. Generally, habitat removal was more effective than one‐off pesticide treatments at causing extinction.

Synthesis and applications. Spatially explicit modelling of Allee dynamics in invading gypsy moth populations showed that host removal can be an effective method to eradicate invasive plant‐feeding insects especially when habitat fragmentation is applied at a desirable level. Furthermore, this can be used as an alternative to, or in conjunction with, pesticide treatments, to provide more options for carrying out eradications and to increase the probability of eradication success.

Published: December 2019

AbstractObjectiveTo explore women's expectations and experiences when presenting to the ED with early pregnancy bleeding.MethodsWe conducted a qualitative study where women presenting to the ED with early pregnancy bleeding participated in two semi‐structured interviews. An initial interview explored expectations of care and was conducted prior to ED treatment. A follow‐up interview about experiences with care was conducted after discharge from the ED. Women were recruited from three EDs in suburban Melbourne: one tertiary referral centre and two urban district hospitals.ResultsThirty women with early pregnancy bleeding completed the initial interview and 22 completed the follow‐up interview. Eleven participants were primigravid women and 21 participants had never experienced early pregnancy bleeding prior to their ED presentation. Four themes relating to the patient experience were identified: (i) Acknowledgement of patients' concerns by hospital staff, including informing patients of progress and explanation of investigation results; (ii) Early pregnancy bleeding as a distressing experience, with most participants expecting that this would be acknowledged by ED staff, and privacy provided to allow for grieving; (iii) Prolonged waiting time for an urgent medical condition; and (iv) Ongoing care and support, such as providing recommendations of available services to support patients on discharge from the ED.ConclusionEarly pregnancy bleeding is a distressing and anxiety‐provoking experience for women attending the ED. Appropriate emotional support is critical to the holistic care for those seeking emergency care.
Camponotus ants mine sand for vertebrate urine to extract nitrogen

Published: December 2019

AbstractThe ability of some ant species (including Camponotus spp.) to forage on vertebrate urine to extract urea may extend their niche in competitive and strongly nitrogen‐limited environments. We examined the preference of Camponotus terebrans, a sand‐dwelling ant widespread in southern Australia, for baits including urine, and the duration of their foraging on those baits. We baited ants with liquid stains of urine (human and kangaroo), urea in water (2.5%. 3.5%, 7.0%, 10.0%) and sucrose in water (20% and 40%) poured directly on the ground, as well as hard baits in plots drawn on sandy soil (Kangaroo Island, South Australia). We counted individuals of this mostly nocturnal species to determine their attraction to different baits for one month. We checked plant growth on the plots after nine and 13 months. Ants collected insects and meat; they foraged for at least 29 days on stains. Ants were most numerous on 10% urea, followed by 7% urea, 3.5% urea, urine (which contains ~2.5% urea) and 2.5% urea, 40% sucrose and 20% sucrose; sucrose was less attractive to them than equimolar urea bait. Ants were attracted to human, kangaroo, and unidentified urines, and they collected bird guano. Baits and ant foraging did not affect plant recruitment in plots. We observed incidentally Camponotus consobrinus foraging on urine, which may be a common resource for this genus at the site. The remarkable ability of C. terebrans to extract nitrogen from dry sand over weeks explains partly its success on sandy soils. Foraging on urine may be an important strategy to address nitrogen limitation on sandy soils and exploit commensally niches in which hosts are kangaroos, wallabies and other vertebrates. The understanding of plant–vertebrate interactions must factor in the role of ants as commensal organisms. Such ants could also reduce greenhouse gas emissions from urine.

AbstractAimHypertension has been reported in up to 4.0% of American children, but no national data exist in Europe. We studied the frequency of registered hypertension in Danish children and evaluated the data.MethodsThis 2014‐2015 study focused on patients under the age of 16 registered with hypertension in the Danish National Patient Register and 10 paediatric departments in central and eastern Denmark. The diagnoses were coded according to the International Classification of Diseases, 10th revision. All the subjects’ medical records were reviewed, including any confirmed diagnoses.ResultsThere were 55 784 children under 16 in the study regions at 30 April 2014. By May 2015, 222 of those had been registered with hypertension: 200 in the Danish National Patient Register and 191 in the 10 paediatric departments. Their medical records confirmed hypertension in 187 and 185 cases, respectively. The prevalence of registered and confirmed hypertension was 222/553 784 (0.04%). The positive predictive values of hypertension were 187/200 (94%) and 185/191 (97%), and the completeness of diagnosed hypertension was 187/222 (84%) and 185/222 (83%).ConclusionThe registers had high‐quality positive predictive values and completeness, but only 0.04% of the Danish children were registered with a verified diagnosis of hypertension.
