Authors: Al-Hawari Mohd A. , Bani-Melhem Shaker , Shamsudin Faridahwati Mohd 
Published: August 2019

PurposeThe purpose of this study is to examine the influence of workplace happiness and work engagement on employee service innovative behavior from the perspective of positive psychology. The study also examines if work engagement mediates the relationship between workplace happiness and employee service innovative behavior. Finally, it investigates how co-worker socializing and the service climate of the organization moderate the relationship between work engagement and employee service innovative behavior.Design/methodology/approachThe study used survey data from 321 frontline employees working in the service sector in the United Arab Emirates (UAE). Six major hypotheses were established and examined using the SPSS Statistics V22.0 Process. The measurement model was analyzed using Amos 22.FindingsWorkplace happiness and work engagement are found to be important factors affecting employee service innovative behavior. Workplace happiness influences employee service innovative behavior directly and indirectly through work engagement. Both service climate and co-worker socializing play a significant moderating role in the relationship between work engagement and employee service innovative behavior among frontline employees. Interestingly, service climate erodes this relationship while co-worker socializing enhances it.Practical implicationsThis study provides guidelines for managers and practitioners in the service industry to promote frontline employee service innovative behavior. Specifically, the findings provide guidance for decision-makers on how to use workplace happiness to trigger the innovative service behaviors of frontline employees, taking into consideration the conditional role of service climate and co-worker socializing.Originality/valueThe literature on factors affecting the service innovative behavior of frontline employees in the service sector from the perspective of positive psychology is limited, especially in the context of the UAE. The data, framework and outcomes of this research address this gap and contribute to the current body of knowledge. Specifically, the study contributes to the broaden-and-build theory of positive emotions in the field of positive psychology by validating the applicability of the theory in a wider organizational context.
Fighting organizational decline: a risk-based approach to organizational anti-aging
Authors: Gotteiner Sharon , Mas-Machuca Marta , Marimon Frederic 
Published: August 2019

PurposeMost mature organizations face a major decline in performance at some time during their existence. For more than three decades, it has been suggested that the management practices that could cure a troubled company could have also kept it well. Inspired by this concept, this paper is proposing a preventive approach to early implementation of turnaround strategies as an alternative for otherwise traumatic rescue efforts, further along the downward spiral.Design/methodology/approachCorporate turnaround strategies and associated risks are integrated with a risk-based approach, along with a proactive decision-making process. The link between turnaround research, resource-based view, the sources of organizational decline, and the governance of organizational-decline-related risks – is explained.FindingsThe integrated model streamlines a preventive organizational process for considering the suitability of commonly used turnaround practices – for the non-crisis business routine of a mature company. By considering and adjusting the risks associated with such practices, it addresses risk aversion at the early stages of decline and determines the optimal sequence and timing of retrenchment and recovery activities. As such, it encourages mature companies to take actions for reducing their exposure to organizational decline. Accordingly, the model is named the “Anti-Aging” framework.Research limitations/implicationsEmpirical testing of the suitability of turnaround strategies for non-crisis situations is proposed as a direction for future research.Practical implicationsThe Anti-Aging framework opens an opportunity for the senior management of a mature organization to respond earlier to organizational decline and avoid the trauma associated with otherwise more challenging conditions, for the benefit of all stakeholders.Originality/valueThe Anti-Aging framework proposes an innovative way of bridging the gap between the benefits of early implementation of turnaround strategies, and major obstacles faced by willing, traditional management teams of mature organizations.

Published: August 2019

PurposeImproving valuation accuracy, especially for sale and acquisition purposes, remains one of the key targets of the global real estate research agenda. Among other recommendations, it has been argued that the use of technology-based advanced valuation methods can help to narrow the gap between asset valuations and actual sale prices. The purpose of this paper is to investigate the property valuation methods being adopted by Australian valuers and the factors influencing their level of awareness and adoption of the methods.Design/methodology/approachAn online questionnaire survey was conducted to elicit information from valuers practising in Australia. They were asked to indicate their level of awareness and adoption of the different property valuation methods. Their response was analysed using frequency distribution,χ2test and mean score ranking.FindingsThe results show that the traditional methods of valuation, namely, comparative, investment and residual, are the most adopted methods by the Australian valuers, while advanced valuation methods are seldom applied in practice. The results confirm that professional bodies, sector of practice and educational institutions are the three most important drivers of awareness and adoption of the advanced valuation methods.Practical implicationsThere is a need for all the property valuation stakeholders to synergise and transform the property valuation practice in a bid to promote the awareness and adoption of advanced valuation methods, (e.g. hedonic pricing model, artificial neural network, expert system, fuzzy logic system, etc.) among valuers. These are all technology-based methods to improve the efficiency in the prediction process, and the valuer still needs to input reliable transaction data into the systems.Originality/valueThis study provides a fresh and most recent insight into the current property valuation methods adopted in practice by valuers practising in Australia. It identifies that the advanced valuation methods could supplement the traditional valuation methods to achieve good practice standard for improving the professional valuation practice in Australia so that the valuation profession can meet the industry’s expectations.
Urban shared energy systems and behaviour change − simulating a common pooled resource problem
Authors: Burton Craig Alexander , Ryan Christopher , Rismanchi Behzad , Candy Seona 
Published: August 2019

Purpose
The purpose of this paper is to test a new methodology for simulating shared electricity generation among small groups of neighbours with Ostrom’s (1994) principles of common pool resource (CPR) (human behaviour-based) efficiencies. The approach does not anticipate exclusive off-grid communities but instead, diverse energy users taking advantage of the averaging effects of aggregation, the social benefits of a CPR and direct action on emissions.

Design/methodology/approach
The study tested three groups of five adjacent − or same-building − neighbours for three months to measure how electricity demand (import) is affected by an in-home display issuing nudges and sanctions by the group around a simulated (limited capacity) shared solar and battery system. A control group of six homes’ energy data was obtained for the same period.

Findings
Two groups reduced their energy demand with weak but significant correlation between stimulus and reduced energy demand and one group increased demand. There were no significant effects in time-of-use behaviours.

Research limitations/implications
The study shows that the interaction between consumers and energy systems can in this instance be simulated with inexpensive equipment. Studying dynamic interactions between people and systems provides new data where supply simulations have been one-sided. There is support in this work that the energy supply can be presented as a rivalrous commons system.

Practical implications
Urban adjacent neighbours (and apartment occupants in the same building or campus) exhibit emergent group behaviours around electricity use conservation and time-of-use. Managing energy demand is very difficult but very important for making consumer behaviour “fit” the future supply of energy which may be unreliable and limited.

Social implications
There are likely social benefits and other overflow benefits when neighbours can share a critical resource. There are other critical services that may be managed according to the Ostrom commons principles. The sharing group will be more resilient in terms of electricity but also in terms of social capital.

Originality/value
The work builds on the work of Rachel Coxcoon and others who have identified that groups perform better at certain challenges than individuals do. This aligns with scale and operational efficiencies in shared renewable energy infrastructure. Shaping behaviour and the generation systems together for optimal outcomes is new work.

Authors: Gandjon Fankem Gislain Stéphane , Tchoue Houli Michel Scott 
Published: August 2019

RésuméL'objectif de cet article est de déterminer empiriquement la nature de la relation de causalité entre consommation d'énergie électrique et croissance économique pour cinq pays d'Afrique Centrale. La méthodologie utilisée repose sur un cadre multivarié théoriquement fondé et des récents développements en économétrie des données de panel des: tests de racine unitaire, tests de cointégration, estimateurs des moindres carrés ordinaires entièrement modifiés (FMOLS) et moindres carrés ordinaires dynamiques (DOLS) et du modèle vectoriel à correction d'erreur (VECM). Sur la période 1990–2015, les principaux résultats mettent en évidence une causalité bidirectionnelle entre la consommation d'énergie électrique et la croissance économique à la fois à court et à long terme. Celle‐ci reste stable même après contrôle pour le capital et le travail. Ces résultats constituent ainsi une base solide pour la formulation des politiques et des programmes énergétiques appropriées qui favoriseraient l'accès à l'énergie électrique et la croissance économique.
Proteolysis and textural properties of low‐fat ultrafiltered Feta cheese as influenced by maltodextrin
Authors: Nazari Seyyed Moein , Mortazavi Ali , Hesari Javad , Tabatabaei Yazdi Farideh 
Published: August 2019

Maltodextrin was used as a fat replacer in low‐fat ultrafiltered cheese. Fat was replaced with 25% maltodextrin milk solution (w/w) in cheese at 15 and 50% (w/w). The chemical, rheological and sensory properties as well as the microstructure of the cheese samples were evaluated after storage for 2 months at 8 °C. Maltodextrin affected the chemical (pH, dry matter, fat, water‐soluble nitrogen to total nitrogen, nonprotein nitrogen to total nitrogen, total free amino acid) and rheological (mean relaxation time) properties, as well as the microstructure. In general, based on textural properties, sensory evaluation and economic aspects, the 50%‐fat‐reduced sample was selected as the best treatment.

Authors: Zhang Rongju , Zhang Shaohui , Xing Rongge , Zhang Qin 
Published: August 2019

BackgroundTo evaluate the EZR (ezrin) gene expression in breast cancer and correlation with the prognosis through bioinformatics analysis and immunohistochemistry assay.MethodsEZR gene expression in breast cancer and corresponding normal breast tissue was compared in the TCGA database. Protein‐protein interaction (PPI) network relevant EZR was established through the STRING database. The correlation between EZR expression and prognosis of breast cancer was analyzed by the log‐rank analysis from the TCGA. Ezrin protein (coded by EZR) expression was also examined by immunohistochemistry assay in 120 breast cancer patients.ResultsEZR expression level in tumor tissue was significantly upregulated compared to that of normal breast tissue of breast cancer patients (P < 0.05). In the PPI analysis, there were 51 nodes and 455 edges in the network. The top 10 hub genes of the network were identified. High expression of EZR mRNA was correlated with poor overall survival (OS) of the breast cancer patients (HR = 1.40, P = 0.038). However, the disease‐free survival (DFS) of breast cancer patients did not correlate with the EZR mRNA level (HR = 0.86, P = 0.44). The ezrin protein expression was positive with uniform brown‐yellow granules in the cell membrane, cavity surface and cytoplasm of the breast cancer cells. Of the included 120 cancer samples, 98 cases were positive for ezrin expression and 22 were negative. No correlation was found between ezrin expression site and patients’ clinicopathological features.ConclusionEZR is upregulated in breast cancer and can be used as potential biomarker for overall survival.
Poaching creates ecological traps within an iconic protected area
Authors: le Roex N. , Dreyer C. , Ferreira S. M. 
Published: August 2019

AbstractEcological traps occur when areas preferentially selected by a species harbour an unknown increased mortality risk or reduced fitness for the individuals utilizing them. If animals continue to utilize these habitats, rapid declines may result that threaten the persistence of the population. Both black and white rhinoceroses are plagued by severe, targeted rhino poaching in South Africa that may have population and species‐level consequences in the long term. Poaching can rapidly increase mortality and may create habitats that function as ecological traps for protected populations. We used spatially explicit data of live rhino and poached rhino carcasses in the Kruger National Park, South Africa, to define high‐ and low‐risk states for both black and white rhino species. The proportion of area functioning as ecological trap was similar for both species (black: 37.73%, white: 35.51%), while the proportion of safe harbour was considerably lower for black rhino (black rhino: 32.01%, white rhino: 44.74%). Species‐specific risk areas were condensed into management categories that reflect the actions most likely to be effective for overall rhino protection in those areas. ‘Threat’ area, representing ecological traps for both species, comprised 32.48% of southern Kruger; this represents the highest priority for anti‐poaching interventions. A further 31.03% was identified as ‘haven’, representing safe harbours for both species, which may benefit most from continued rhino monitoring and surveillance. Using these categories, authorities can prioritize the distribution of limited resources and tailor anti‐poaching and biological management actions according to the needs of each area for the concurrent protection of both rhino species. This work illustrates how the conservation of multiple species or taxa within a system can be simultaneously prioritized in vast areas where resources and/or capacity may be insufficient to undertake species‐specific approaches.

Published: August 2019

AbstractBackgroundThe optimal extent of lymph node dissection in patients with descending colon cancer is still debatable. We designed this study to evaluate the distribution of lymph node metastasis and the appropriate extent of lymph node dissection in descending colon cancer patients.MethodsWe retrospectively reviewed the medical records of 118 descending colon cancer patients without distant metastasis, who underwent curative resection between January 2004 and December 2014. The distribution of lymph node metastasis was evaluated, and prognostic factors were analysed.ResultsThe median follow‐up period was 52 months (range 1–125 months). Twenty‐six (22.0%) patients underwent high ligation of the inferior mesenteric artery (IMA), whereas 92 (78.0%) patients underwent ligation of the left colic artery, saving the IMA. Lymph nodes at the origin of the IMA showed no metastasis in any of the 26 patients who underwent high ligation of the IMA. After propensity score matching, 3‐year disease‐free survival (80.4% versus 92.9%, P = 0.471) and 5‐year overall survival (81.8% versus 90.9%, P = 0.875) were not significantly different according to the type of IMA ligation.ConclusionIn patients with descending colon cancer, there was no lymph node metastasis at the origin of the IMA, and ligation of the IMA showed no prognostic benefit.

AbstractAimOur aim was to update the recommendations for the diagnosis, treatment and follow‐up of the first febrile urinary tract infection in young children, which were endorsed in 2012 by the Italian Society of Pediatric Nephrology.MethodsThe Italian recommendations were revised on the basis of a review of the literature published from 2012 to October 2018. We also carried out an ad hoc evaluation of the risk factors to identify children with high‐grade vesicoureteral reflux or renal scarring, which were published in the previous recommendations. When evidence was not available, the working group held extensive discussions, during various meetings and through email exchanges.ResultsFour major modifications have been introduced. The method for collecting urine for culture and its interpretation has been re‐evaluated. We have reformulated the algorithm that guides clinical decisions to proceed with voiding cystourethrography. The suggested antibiotics have been revised, and we have recommended further restrictions of the use of antibiotic prophylaxis.ConclusionThese updated recommendations have now been endorsed by the Italian Society of Pediatric Nephrology and the Italian Society for Pediatric Infectivology. They can also be used to compare other recommendations that are available, as a worldwide consensus in this area is still lacking.
