Authors: Sun Xiaodong , Zhou Zhuicai , Chen Long , Yang Zebin , Han Shouyi 
Published: March 2018

Purpose
Inductance, torque and iron loss are the key parameters of switched reluctance motors for belt-driven starter generators. This paper aims to present the analysis of a segmented rotor switched reluctance motor (SSRM) with three types of winding connections for hybrid electric vehicle applications by using a two-dimensional finite element method.

Design/methodology/approach
The rotor of the studied SSRM consists of a series of discrete segments, while the stator is made up of exciting and auxiliary teeth. First, the concept and structures of the different winding connections are introduced. Then, the magnetic flux path of the three types of winding connections for the SSRM is described. Second, the magnetic flux distributions in the three parts, i.e. the stator yoke, the stator tooth and the rotor segment, are described in detail to calculate the iron losses. Third, three SSRMs with the different winding arrangements are analyzed and compared to evaluate the distinct features of the studied SSRM. The analysis and comparison mainly include self-inductances, mutual inductances, phase currents, output torque and iron loss.

Findings
It is found that the self-inductances of the three types of winding connections are almost equal, and only the SSRM1 has a positive mutual inductance. In addition, the current waveforms of SSRM1 and SSRM2 are regular. However, it is irregular in SSRM3. It is shown that SSRM1 has better characteristics, such as higher output torque, high power density, lower torque ripple and iron loss.

Originality/value
This paper proposes and analyzes three novel winding connections for the SSRM to provide guidance for enhancing the output torque and reducing the iron loss to achieve high efficiency.

Published: March 2018

PurposeThe purpose of this paper is to review and analyze the perishable inventory models along various dimensions such as its evolution, scope, demand, shelf life, replenishment policy, modeling techniques and research gaps.Design/methodology/approachIn total, 418 relevant and scholarly articles of various researchers and practitioners during 1990-2016 were reviewed. They were critically analyzed along author profile, nature of perishability, research contributions of different countries, publication along time, research methodologies adopted, etc. to draw fruitful conclusions. The future research for perishable inventory modeling was also discussed and suggested.FindingsThere are plethora of perishable inventory studies with divergent objectives and scope. Besides demand and perishable rate in perishable inventory models, other factors such as price discount, allow shortage or not, inflation, time value of money and so on were found to be combined to make it more realistic. The modeling of inventory systems with two or more perishable items is limited. The multi-echelon inventory with centralized decision and information sharing is acquiring lot of importance because of supply chain integration in the competitive market.Research limitations/implicationsOnly peer-reviewed journals and conference papers were analyzed, whereas the manuals, reports, white papers and blood-related articles were excluded. Clustering of literature revealed that future studies should focus on stochastic modeling.Practical implicationsStress had been laid to identify future research gaps that will help in developing realistic models. The present work will form a guideline to choose the appropriate methodology(s) and mathematical technique(s) in different situations with perishable inventory.Originality/valueThe current review analyzed 419 research papers available in the literature on perishable inventory modeling to summarize its current status and identify its potential future directions. Also the future research gaps were uncovered. This systemic review is strongly felt to fill the gap in the perishable inventory literature and help in formulating effective strategies to design of an effective and efficient inventory management system for perishable items.
Anti-competition of ocean shipping alliances: a legal perspective
Authors: Tang Owen , Sun Po-wan 
Published: March 2018

Purpose
Antitrust exemptions to shipping alliances in the liner shipping sector have prevailed for many years. This study aims to examine anti-competition of ocean shipping alliances from a legal perspective of the USA, the European Union (EU) and People’s Republic of China (PRC).

Design/methodology/approach
Adopting the standard “doctrinal approach to legal research and analysis” in legal literatures, this paper reviews landmark court cases and legislations in the USA relating to shipping conference system from its beginning to its erosion, followed by its latest transition to non-ratemaking agreements, with discussions on the EU and some PRC treatments on shipping conferences.

Findings
Although antitrust exemptions to shipping conferences in the liner shipping sector were eliminated in the trades to/from the USA and the EU, there is a lack of evidence of the deterioration found in the viability of liner shipping carriers in both parts of the world trades. For the USA, shipping alliances will shift the focus to sharing resources for improvement of collective operational efficiencies, whereas the shipper groups in the EU have worried that a protected system of sharing information may lead to price fixing conducts among the carriers.

Practical implications
Through the discussions on the legal treatments of shipping conferences from the USA, the EU and PRC perspectives, this paper provides legal researchers with not only a new research direction on raising collective operational efficiencies through resource sharing but also an insight into shifting their research focus from purely price determination to the area of merger.

Originality/value
This paper reviews landmark court cases and related legislations about the treatments of different regulatory regimes, including the USA, the EU and PRC, to explore the illegitimacy of anti-competition conducts in ocean shipping alliances.
CSR perception as a signpost for circular economy
Authors: Esken Björn , Franco-García María-Laura , Fisscher Olaf A.M. 
Published: March 2018

Purpose
This paper aims to identify managerial implications for multinational corporations (MNCs) with regard to circular economy (CE) by using data on corporate social responsibility (CSR) perception in different types of market economies owing to diverse institutional contexts. These managerial implications can contribute to the linking of CSR and CE strategies for MNCs.

Design/methodology/approach
This is an empirical study with a mixed-methods approach using both quantitative and qualitative research elements. The varieties of capitalism (VOC) approach with its two kinds of market economies – liberal market economy (LME) and coordinated market economy (CME) – builds the theoretical foundation.

Findings
All three guiding hypotheses of the quantitative research part are confirmed, which are: there is a differing perception of CSR in the two kinds of VOC; LME corporations adopt a shareholder value perspective; and CME corporations adopt a stakeholder values perspective. Furthermore, the qualitative research part has identified several key success factors for strategically conducting CSR in nexus with CE.

Practical implications
The mentioned key success factors become managerial implications for MNCs aiming at strategically conducting CSR. Due to several crossing points between (strategic) CSR and CE, those implications are largely also eligible for CE.

Originality/value
The paper helps to propel empirical findings into a more up-to-date discourse of debate. By emphasizing that the institutional background is likely to have an effect on how CSR is perceived in different kinds of market economies, the research offers a proposition how to use CSR perception as a signpost for CE and fuel future research into this direction.
Corporate reputation
Authors: Pires Vanessa , Trez Guilherme 
Published: March 2018

PurposeThe purpose of this paper is to discuss the different approaches to the corporate reputation construct, in order to identify a comprehensive definition that can be used for measurement purposes, gaps identified by previous literature identified.Design/methodology/approachThis is a theoretical essay. The authors analyzed studies that involve the relationship between corporate reputation and organizational performance, and the attributes of national and international corporate reputation ratings.FindingsThe authors identified a more comprehensive definition for the reputation construct, and indicated courses for the construct’s measurement, by considering: the judgment by the stakeholders (internal, suppliers, clients and the financial market); periodical evaluations under different organizational perspectives; attention to theoretical assumptions, among other aspects.Research limitations/implicationsThe study is a theoretical paper that presents that the research field has many definitions that cannot be used interchangeably. It indicated how the reputation construct should be operationalized for measurement purposes. This study presented a reflection on the relationship between corporate reputation and performance, showing that it is not a settled topic in the academy.Practical implicationsThe study advances the understanding of the reputation construct measurement, considering the adopted definition and the discussion of the attributes of the main ratings on corporate reputation. The adoption of a measurement method that takes into account the definition used in this study and the features of the methodologies discussed will improve the corporate reputation assessment.Social implicationsLiterature indicates that a good corporate reputation can affect organizational performance and the inverse relationship is also true. As a social implication, it is extremely relevant to improve the understanding the definition and measurement methods of this construct.Originality/valueThis study discusses one of the most important intangible resources for organizations, contributing to the understanding of the difference between the market value and the book value of public companies. Besides it should be considered that there is one lack of a definition directly related to the measurement of the reputation construct in the literature, a gap in which this study contributes.
Towards the general mechanistic prediction of community dynamics

Published: March 2018

Abstract

“What controls the distribution and abundance of organisms”? This question, at the heart of the dynamics of ecological communities, would have been familiar to the earliest ecologists. Having lain effectively abandoned for many years, community dynamics today is a vibrant research topic of great conceptual interest with practical import for conservation, ecological management, ecosystem services and the responses of ecological communities to climate change.

We describe how modern coexistence theory can be used to predict community dynamics through the use of demography. We explore the challenges that limit the deployment of this demographic framework, and the tools from phylogenetic and functional ecology that have been used to surmount them.

Finding existing tools not altogether sufficient, we propose the use of “hard” functional traits and physiological tolerances of environmental conditions and low resource availability to extend the demographic framework so that the dynamics of a broader range of ecological communities can be accurately predicted.

We illustrate these new approaches with two case studies. Given the urgent need to accurately forecast the dynamics of ecological communities, we hope that many ecologists will adopt these tools.

Management of multiple threats achieves meaningful koala conservation outcomes

Published: March 2018

Abstract

Management actions designed to mitigate development or anthropogenic impacts on species of conservation concern are often implemented without quantifying the benefit to the species. It is often unclear what combinations and intensities of management actions are required to achieve meaningful conservation outcomes. We investigate whether disease and predator control can reverse population declines of koalas (Phascolarctos cinereus).

Based on longitudinal monitoring of the epidemiological and demographic status of over 500 animals over 4 years, coupled with an intensive disease and predator management programme, we use survival analyses to estimate annual age‐specific survival rates and population growth, and simulations to quantify the benefit of these actions.

Predation and disease accounted for 63% and 29% of mortality, respectively, across all years, with wild dog (dingoes or dingo‐hybrids: Canis dingo, C. dingo × Canis familiaris), carpet pythons (Morelia spilota) and domestic dogs (C. familiaris) accounting for 82%, 14% and 4% of confirmed predation mortalities, respectively. In the first 2 years, before disease and dog control had major impact, the population was declining rapidly with annual growth rates of 0.66 and 0.90. In the third and fourth years, after interventions had been fully implemented, the population growth rate had increased to 1.08 and 1.20. The intrinsic survival rate of joeys was 71.2% (excluding deaths resulting from the death of the mother). Adult survival rates varied as a function of sex, age and year.

Even in a declining koala population, management actions can achieve meaningful conservation outcomes (population growth rates greater than one). However, benefits may be short‐lived in the absence of longer term strategies to manage threats. This work also identifies wild dogs as a major threat to koalas, highlighting the need to better understand how wild dog impacts vary in space and time.

Policy implications. Offsetting policy that addresses habitat loss alone may achieve little or no meaningful benefit to declining koalas populations. Management must address suites of threats affecting these populations and ensure that the cumulative effects of these actions achieve positive population growth rates.
Water availability drives urban tree growth responses to herbivory and warming
Authors: Meineke Emily K. , Frank Steven D. 
Published: March 2018

Abstract

Urban forests provide important ecosystem services to city residents, including pollution removal and carbon storage. Climate change and urbanization pose multiple threats to these services. However, how these threats combine to affect urban trees, and thus how to mitigate their effects, remains largely untested because multi‐factorial experiments on mature trees are impractical.

We used a unique urban warming experiment paired with a laboratory chamber experiment to determine how three of the most potentially damaging factors associated with global change for urban and rural trees—warming, drought, and insect herbivory—affect growth of Quercus phellos (willow oak), the most commonly planted large shade tree in the southeastern US, which is known for its resilience to these potential stressors.

In a previous study, we found that the urban heat island effect was associated with reduced growth of Q. phellos and higher abundance of Parthenolecanium scale insects, key pests of oaks in cities. Here, we tested the hypothesis that tree water stress is the mechanism for these effects of warming. We found evidence that water stress is a major, interactive factor reducing urban tree growth, but found no evidence that water stress is associated with Parthenolecanium survival or abundance. Warming and Parthenolecanium only reduced growth in Q. phellos saplings that were simultaneously water stressed.

Synthesis and applications. Across many temperate cities worldwide, urban trees grow less than rural trees. Our results point to water stress as the most likely driver for this pattern. Importantly, we found that water stress both reduces tree growth on its own and exacerbates effects of warming and insect pests on tree growth. Therefore, management strategies targeted at increasing tree hydration in cities may reduce effects of these three key stressors that are expected to intensify with further urbanization and climate change.
Inhibition of microRNA‐21‐3p suppresses proliferation as well as invasion and induces apoptosis by targeting RNA‐binding protein with multiple splicing through Smad4/extra cellular signal‐regulated protein kinase signalling pathway in human colorectal cancer HCT116 cells

SummaryMicroRNA‐21‐3p (miR‐21‐3p), the passenger strand of pre‐mir‐21, has been found to be high‐expressing in various cancers and to be associated with tumour malignancy, which is proposed as a novel focus in malignant tumours. Colorectal cancer (CRC), currently known as one of the most prevalent malignancy, is a leading cause of cancer death. This study aimed to investigate the key role of miR‐21‐3p in CRC by inhibiting its expression using transfection with miR‐21‐3p inhibitors into human CRC HCT116 cells. Results showed that the expression of miR‐21‐3p was higher than other CRC cells used in the study including Lovo, HT29, Colo320 and SW480 cells, inhibition of which suppressed the proliferation and induced cell cycle arrest in HCT116 cells. Besides, transfection with miR‐21‐3p inhibitors also attenuated cell migration and invasion, and induced apoptosis as well. Moreover, luciferase assay confirmed RBPMS as a direct target of miR‐21‐3p in HCT116 cells. Further, miR‐21‐3p inhibitors increased the nuclear accumulation of Smad4 and reduced phosphorylation of ERK. Interestingly, we found that silence of RBPMS using RNA interference (siRNA) not only elevated the cell viability but also increased the phosphorylation of ERK and reversed the nuclear accumulation of Smad4 induced by miR‐21‐3p inhibitors in HCT116 cells. Data suggest that inhibition of miR‐21‐3p suppresses cell proliferation, invasion as well as migration and induces apoptosis by directly targeting RBPMS through Smad4/ERK signalling pathway in HCT116 cells. Our study demonstrates miR‐21‐3p as a potent target for suppressing tumour progression of CRC which may have implications in CRC therapy in the future.
Red Lines and Compromises: Mapping Underlying Complexities of Brexit Preferences
Authors: Richards Lindsay , Heath Anthony , Carl Noah 
Published: March 2018

AbstractThe political discourse is characterised by two opposing ideals of hard and soft Brexit. In this article, we present evidence of attitudinal types that map neatly onto these archetypal views. The hard Brexit view is defined by issues that eurosceptics prioritise, most prominently sovereignty. By contrast, europhiles prioritise cooperation with Europe in terms of scientific collaboration and market access. However, attitudinal types are not either/or in the minds of the British public, and many prioritise all or none of the issues. Further, the two opposing positions together account for 37 per cent of the public's view. That is, just over one‐third differentiate between the salient issues in ways congruent with political ideals. National identity plays a particular role in the sociodemographic profiles of these attitude types. Older people have a strong stance in any direction (sovereignty, cooperation, or both), but national identity is linked to differentiated positions (sovereignty only or cooperation only).
Social mobility and demand for redistribution in Europe: a comparative analysis
Authors: Jaime‐Castillo Antonio M. , Marqués‐Perales Ildefonso 
Published: March 2018

AbstractThe literature on preferences for redistribution has paid little attention to the effect of social mobility on the demand for redistribution and no systematic test of the hypotheses connecting social mobility and preferences for redistribution has yet been done to date. We use the diagonal reference model to estimate the effect of origin and destination classes on preferences for redistribution in a large sample of European countries using data from the European Social Survey. Our findings are consistent with the logic of acculturation in the sense that newcomers tend to adapt their views to those of the destination class at early stages and that upward and downward mobility do not have distinctive effects on the formation of political preferences. However, even though social origins seem to have a limited impact on preferences for redistribution, the evidence does not support the hypothesis that mobile and non‐mobile individuals are alike. We also find that the effect of social origin on preferences varies largely across countries. The empirical evidence leads to the conclusion that the effect of social origin on preferences for redistribution increases in contexts of strong familism.
Mindfulness, cognitive behavioural and behaviour‐based therapy for natural and treatment‐induced menopausal symptoms: a systematic review and meta‐analysis

Published: March 2018

BackgroundDuring menopause women experience vasomotor and psychosexual symptoms that cannot entirely be alleviated with hormone replacement therapy (HRT). Besides, HRT is contraindicated after breast cancer.ObjectivesTo review the evidence on the effectiveness of psychological interventions in reducing symptoms associated with menopause in natural or treatment‐induced menopausal women.Search strategyMedline/Pubmed, PsycINFO, EMBASE and AMED were searched until June 2017.Selection criteriaRandomised controlled trials (RCTs) concerning natural or treatment‐induced menopause, investigating mindfulness or (cognitive‐)behaviour‐based therapy were selected. Main outcomes were frequency of hot flushes, hot flush bother experienced, other menopausal symptoms and sexual functioning.Data collection and analysisStudy selection and data extraction were performed by two independent researchers. A meta‐analysis was performed to calculate the standardised mean difference (SMD).Main resultsTwelve RCTs were included. Short‐term (<20 weeks) effects of psychological interventions in comparison to no treatment or control were observed for hot flush bother (SMD −0.54, 95% CI −0.74 to −0.35, P < 0.001, I2 = 18%) and menopausal symptoms (SMD −0.34, 95% CI −0.52 to −0.15, P < 0.001, I2 = 0%). Medium‐term (≥20 weeks) effects were observed for hot flush bother (SMD −0.38, 95% CI −0.58 to −0.18, P < 0.001, I2 = 16%). [Correction added on 9 July 2018, after first online publication: there were miscalculations of the mean end point scores for hot flush bother and these have been corrected in the preceding two sentences.] In the subgroup treatment‐induced menopause, consisting of exclusively breast cancer populations, as well as in the subgroup natural menopause, hot flush bother was reduced by psychological interventions. Too few studies reported on sexual functioning to perform a meta‐analysis.ConclusionsPsychological interventions reduced hot flush bother in the short and medium‐term and menopausal symptoms in the short‐term. These results are especially relevant for breast cancer survivors in whom HRT is contraindicated. There was a lack of studies reporting on the influence on sexual functioning.Tweetable abstractSystematic review: psychological interventions reduce bother by hot flushes in the short‐ and medium‐term.
