• Bacterial biodiversity-ecosystem functioning relations are modified by environmental complexity

      Langenheder, Silke; Bulling, Mark T.; Solan, Martin; Prosser, James I.; Bell, Thomas (2013-05-24)
      Background: With the recognition that environmental change resulting from anthropogenic activities is causing a global decline in biodiversity, much attention has been devoted to understanding how changes in biodiversity may alter levels of ecosystem functioning. Although environmental complexity has long been recognised as a major driving force in evolutionary processes, it has only recently been incorporated into biodiversity-ecosystem functioning investigations. Environmental complexity is expected to strengthen the positive effect of species richness on ecosystem functioning, mainly because it leads to stronger complementarity effects, such as resource partitioning and facilitative interactions among species when the number of available resource increases. Methodology/Principal Findings: Here we implemented an experiment to test the combined effect of species richness and environmental complexity, more specifically, resource richness on ecosystem functioning over time. We show, using all possible combinations of species within a bacterial community consisting of six species, and all possible combinations of three substrates, that diversity-functioning (metabolic activity) relationships change over time from linear to saturated. This was probably caused by a combination of limited complementarity effects and negative interactions among competing species as the experiment progressed. Even though species richness and resource richness both enhanced ecosystem functioning, they did so independently from each other. Instead there were complex interactions between particular species and substrate combinations. Conclusions/Significance: Our study shows clearly that both species richness and environmental complexity increase ecosystem functioning. The finding that there was no direct interaction between these two factors, but that instead rather complex interactions between combinations of certain species and resources underlie positive biodiversity ecosystem functioning relationships, suggests that detailed knowledge of how individual species interact with complex natural environments will be required in order to make reliable predictions about how altered levels of biodiversity will most likely affect ecosystem functioning
    • The bank lending channel and monetary policy rules for Eurozone banks: further extensions

      Apergis, Nicholas; Miller, Stephen; Alevizopoulou, Effrosyni; Curtin University; University of Nevada Las Vegas; University of Piraeus (De Gruyter, 2014-06-12)
      The monetary authorities affect macroeconomic activity through various channels of influence. This paper examines the bank lending channel, which considers how central bank actions affect the loan supply through its main indicator of policy, the real short-term interest rate. This paper employs the endogenously determined target interest rate, emanating from the European Central Bank’s monetary policy rule, to examine the operation of the bank lending channel. Furthermore, it examines whether different bank-specific characteristics affect how Eurozone banks react to monetary shocks. That is, do sounder banks react more to the monetary policy rule than less-sound banks? The paper finds evidence of an active and statistically and economically significant bank lending channel for the Eurozone between 2000 and 2009.
    • Banking development and energy consumption: Evidence from a panel of Middle Eastern countries

      Aslan, Alper; Apergis, Nicholas; Topcu, Mert; Nevsehir University; Curtin University; Nevsehir Haci Bektas Veli University (Elsevier, 2014-06-21)
      Since the late 1990s, much scholarly work has been done in the field of energy economics on the nexus between economic growth and energy consumption. Over the last decade, however, the literature has been recompiled through examining the relationship between energy consumption and a set of variables by referring to the implicit role of economic growth. Based upon finance-energy nexus, this paper attempts to investigate the linkage between the banking development and energy consumption for a panel of seven Middle Eastern countries using panel cointegration and causality techniques over the period 1980–2011. Panel cointegration results show a long-run relationship between energy consumption, income, energy prices and banking sector development indicators. FMOLS (Fully Modified OLS) results reveal that all banking sector indicators affect energy demand positively in the long-run and the impact range falls between 0.169 and 0.396. In terms of causality, there is evidence of a one way short-run relationship from banking expansion to energy consumption while long-run dynamics indicate a bi-directional feedback relationship. These results have some implications for energy and environmental policy. One main implication is that energy conservation policies may be implemented with little or no adverse impact on financial development in the short-run whereas they might become detrimental in the long-run.
    • Barriers in green lean implementation: a combined systematic literature review and interpretive structural modelling approach

      Cherrafi, Anass; Elfezazi, Said; Garza-Reyes, Jose Arturo; Benhida, Khalid; Mokhlis, Ahmed; Cadi Ayyad University; University of Derby (Taylor and Francis, 2017)
      Green Lean has recently emerged as an alternative strategy for organizations to pursue both operational and sustainability excellence. The interest on this approach has rapidly risen in both academic and industry circles. However, despite this interest, very limited research has focused on its implementation, and no research has investigated the barriers that hinder the success of such activity. This study investigates the Green Lean implementation barriers and their contextual relationships and effects on the integration and deployment of this approach. A Systematic Literature Review (SLR), Interpretative Structural Modelling and fuzzy Matriced’ Impacts Croise’s Multiplication Appliqée a UN Classement (MICMAC) analyzes were carried out. Fifteen barriers were extracted from the SLR and then validated in consultation with industry and academic experts. The Interpretive Structural Modelling (ISM) method was used to understand the relationship between the fifteen barriers and to develop a hierarchical model of these. The different barriers were classified into ‘linkage’ and ‘dependent’ barriers by using MICMAC analysis. The results suggested that all the identified barriers play an important role, and hence can equally act as a significant hurdle to the implementation of Green Lean projects. This study can help managers and policy makers in better understanding these barriers. Thus, they can be assisted in managing and prioritizing barriers towards the successful implementation of Green Lean initiatives for better financial and environmental performance.
    • Barriers to innovation in service SMEs: Evidence from Mexico

      Maldonado-Guzman, Gonzalo; Garza-Reyes, Jose Arturo; Pinzon-Castro, Sandra Yesenia; Kumar, Vikas; The University of Derby (Emerald, 2017)
      Purpose – Specific research related to the study of innovation barriers in service SMEs in the Latin American region is limited. This study thus investigates the effects that external environmental, financial and human barriers have on innovation activities, particularly, within the context of Mexican service SMEs. Design/methodology/approach – Three hypotheses were formulated and tested using structural equation modelling (SEM). Data were collected through an instrument that was developed based on relevant constructs adapted from the literature. The instrument was validated using Confirmatory Factor Analysis, Cronbach’s alpha test and Composite Reliability Index to ensure the reliability of the theoretical model. The instrument was distributed among service SMEs in the Aguascalientes state of Mexico, from were 308 valid responses were obtained. Findings – In general, the results indicate that all of the three barriers investigated (i.e. external environmental, financial and human) hinder innovation in service SMEs, with the external environmental barrier being the most significant of the three. Practical implications – The findings of this research can inform managers of service SMEs and policy makers when formulating and implementing strategies to reduce innovation barriers. Originality/value – Evidence suggests that specific research related to the study of innovation barriers in service SMEs in the Latin American region is limited. This paper fills this research gap by expanding the limited body of knowledge in this field and providing further evidence on this phenomenon. The study also enables the distinctive characteristics of innovation barriers to be understood within a particular context, expanding in this way the body of knowledge on this field.
    • Baseline coral disease surveys within three marine parks in Sabah, Borneo

      Sweet, Michael J.; Wood, Elizabeth; Miller, Jennifer; Bythell, John C.; University of Derby; School of Biology, Newcastle University, Newcastle upon Tyne, UK; School of Biology, Newcastle University, Newcastle upon Tyne, UK; Marine Conservation Society, Ross-On-Wye, UK; School of Biology, Newcastle University, Newcastle upon Tyne, UK (PeerJ Inc., 2015-11-03)
      Two of the most significant threats to coral reefs worldwide are bleaching and disease. However, there has been a scarcity of research on coral disease in South-East Asia, despite the high biodiversity and the strong dependence of local communities on the reefs in the region. This study provides baseline data on coral disease frequencies within three national parks in Sabah, Borneo, which exhibit different levels of human impacts and management histories. High mean coral cover (55%) and variable disease frequency (mean 0.25 diseased colonies m−2) were found across the three sites. Highest disease frequency (0.44 diseased colonies per m 2) was seen at the site closest to coastal population centres. Bleaching and pigmentation responses were actually higher at Sipadan, the more remote, offshore site, whereas none of the other coral diseases detected in the other two parks were detected in Sipadan. Results of this study offer a baseline dataset of disease in these parks and indicate the need for continued monitoring, and suggest that coral colonies in parks under higher anthropogenic stressors and with lower coral cover may be more susceptible to contracting disease.
    • Baseline reef health surveys at Bangka Island (North Sulawesi, Indonesia) reveal new threats

      Fratangeli, Francesca; Dondi, Nicolò; Segre Reinach, Marco; Serra, Clara; Sweet, Michael J.; Ponti, Massimo; University of Derby; Dipartimento di Scienze Biologiche, Geologiche e Ambientali, University of Bologna, Ravenna, Italy; Reef Check Italia onlus, Ancona, Italy; Reef Check Italia onlus, Ancona, Italy; et al. (PeerJ Inc., 2016-10-25)
      Worldwide coral reef decline appears to be accompanied by an increase in the spread of hard coral diseases. However, whether this is the result of increased direct and indirect human disturbances and/or an increase in natural stresses remains poorly understood. The provision of baseline surveys for monitoring coral health status lays the foundations to assess the effects of any such anthropogenic and/or natural effects on reefs. Therefore, the objectives of this present study were to provide a coral health baseline in a poorly studied area, and to investigate possible correlations between coral health and the level of anthropogenic and natural disturbances. During the survey period, we recorded 20 different types of coral diseases and other compromised health statuses. The most abundant were cases of coral bleaching, followed by skeletal deformations caused by pyrgomatid barnacles, damage caused by fish bites, general pigmentation response and galls caused by cryptochirid crabs. Instances of colonies affected by skeletal eroding bands, and sedimentation damage increased in correlation to the level of bio-chemical disturbance and/or proximity to villages. Moreover, galls caused by cryptochirid crabs appeared more abundant at sites affected by blast fishing and close to a newly opened metal mine. Interestingly, in the investigated area the percentage of corals showing signs of ‘common’ diseases such as black band disease, brown band disease, white syndrome and skeletal eroding band disease were relatively low. Nevertheless, the relatively high occurrence of less common signs of compromised coral-related reef health, including the aggressive overgrowth by sponges, deserves further investigation. Although diseases appear relatively low at the current time, this area may be at the tipping point and an increase in activities such as mining may irredeemably compromise reef health.
    • Be your dog.

      Bartram, Angela; University of Lincoln (KARST Gallery, Plymouth, 06/11/2016)
      In partnership with the Live Art Development Agency, 'Be Your Dog' is a project that aims to transcend the hierarchies of pet and owner. The project sees humans and their dogs aim to demonstrate a connection with each other based on mirrored actions that demonstrate empathy and equality. This public event is a result of workshops, and you may see pairs sitting or laying together, looking in each others eyes, or involved in small reciprocal actions. Of course this might not happen, as all are collaborators and the dogs will bring their own contribution to the work, but whatever happens you will see collaborating pairs being responsive in whatever way they deem right.

    • The behavior, ecology, and social evolution of New World monkey

      Fernández-Duque, Eduardo; Di Fiore, Anthony; Huck, Maren; Department of Anthropology , University of Pennsylvania , Philadelphia; German Primate Centre, Department Behavioural Ecology and Sociobiology; Department of Anthropology, University of Texas (University of Chicago Press, 2012)
      Compared with other primates, New World monkeys display relatively limited ecological variability. New World monkey anatomy and social systems, however, are extremely diverse. Several unique morphological features (e.g., claws, prehensile tails) and uncommon patterns of social organization (e.g., paternal care, cooperative breeding, female dispersal) have evolved in some platyrrhine species. Social organization and mating patterns include typical harem- like structures where mating is largely polygynous, and large multimale, multifemale groups with promiscuous mating and fi ssion- fusion societies. In addition, some species are socially monogamous and polyandrous. Even closely related species may exhibit strikingly different social organizations, as the example of the squirrel monkeys demonstrates (Mitchell et al. 1991; Boinski et al. 2005b). New World monkey behavior varies within species as well as between them. While the behavior of many species is known from only one study site, intriguing patterns of intraspecific variation are beginning to emerge from observations of populations that sometimes live in close proximity. For example, spider monkeys are often described as showing sex- segregated ranging behavior. Several studies show that males range farther, travel faster, and use larger areas than females, who tend to restrict their habitual ranging to smaller core areas within a group’s large territory (Symington 1988; Chapman 1990; Shimooka 2005). In at least one well- studied population in Yasuní National Park, Ecuador, however, males and females both travel over the entire community home range, and different females within the community show little evidence of occupying distinct core areas (Spehar et al. 2010). Similarly, in most well- studied populations of spider monkeys, females disperse and the resident males within a group are presumed to be close relatives—a suggestion corroborated by genetic data for one local population of spider monkeys in Yasuní. Still, in a different local population, males are not closely related to one another, an unexpected pattern if signifi cant male philopatry were common (Di Fiore 2009; Di Fiore et al. 2009). While the causes of this local variation in group genetic structure are not clear, it may be signifi cant that the groups examined likely had different histories of contact with humans. For longlived animals who occupy relatively small social groups, the loss of even a handful of individuals to hunting, or to any other demographic disturbance, can have a dramatic impact on a group’s genetic structure. Intragroup social relationships, in turn, are likely to be infl uenced by patterns of intragroup relatedness and by the relative availability of social partners of different age or sex class (chapter 21, this volume). Thus, historical and demographic contingencies are likely to create conditions where considerable local, intrapopulation variation in social systems exists. Slight changes in ecological conditions may also contribute to variation in the behavior of individuals living in a single population over time. For example, some authors have hypothesized that howler monkey populations may undergo dramatic fluctuations in size and composition in response to several ecological factors, including resource abundance, parasite and predation pressure, and climate (Milton 1982; Crockett & Eisenberg 1986; Crockett 1996; Milton 1996; Rudran & Fernandez- Duque 2003). This variability, not only among populations, but also within populations across time highlights the need for long- term studies. In sum, our understanding of the behavior of New World monkeys has increased dramatically over the past 25 years. This understanding highlights how their behavior varies within populations over time and among populations or species across space. As our knowledge of platyrrhine behavior continues to unfold and is enriched via additional long- term studies, a central challenge will be to explain how these variations arise. It will be important to entertain adaptive explanations while acknowledging that some differences may emerge via stochastic changes in demography (Struhsaker 2008) or nongenetic, relatively short- term, nonadaptive responses to sudden ecological change.
    • The behaviour of interest rate spreads prior to and after the financial crisis: evidence across OECD countries.

      Apergis, Nicholas; Cooray, Arusha; University of Piraeus; University of New South Wales (Wiley, 2018-03-09)
      This study investigates the impact of the 2008 global financial crisis on interest rate spreads across OECD countries, using a number of panel methodological approaches, over the 1990–2015 period. We examine the differential impact of the global financial crisis on interest rate spreads by dividing the sample period into two, i.e. the period prior to and after the crisis. Having identified and estimated the impact of a number of drivers on interest rate spreads, the findings document that after the 2008 financial crisis, the sensitivity of spreads to its determinants turn out to be statistically significant and incorporate credit risk to a greater extent. The findings survive a number of robustness checks. The policy implications of the empirical findings are also discussed.
    • Behavioural competencies of sustainability leaders: An empirical investigation

      Knight, Beth; Paterson, Fred; University of Derby; University of Cambridge (Emerald, 2018-05-14)
      Purpose: Our world faces greater environmental, social and governance challenges than ever before and a growing number of organisations are establishing sustainability functions, strategies and plans in an effort to address these complex issues. However, limited research exists on the critical behavioural competencies required to maximise leadership impact on sustainability initiatives. With the stakes so high and the task so complex, this empirical study identifies key behavioural competencies of corporate sustainability leaders and sets out a model for assessing these behavioural competencies. Design: Based on a review of the empirical literature, the study sets out five competency groupings, which informed a hypothesis. This was tested quantitatively via a self-report tool that enabled a quantitative analysis of behavioural competencies. Contributions from 97 participants were triangulated with data collected from colleagues who rated the participants on the same set of competencies. Findings: Ten critical and ten prominent behaviours of Sustainability Leaders in five competency groupings were idenified. The analysis also explored how the business sector, location, years of experience and level of qualification impacted upon the sample Sustainability Leaders’ perceived effectiveness. Research limitiation/implications: The sample size means that the competency model derived from the findings should be seen as propositional and requiring further validation. Impact measures would add considerable robustness to the findings. Practical implications: The research offers a means to better focus and tailor leadership development experiences and as a tool for the recruitment of Sustainability Leaders. Originality/value: The study is based on a robust quantitative approach, and the behavioural competency model developed as a result provides a tool for Sustainability Leaders to map current behaviours and monitor their progress over time. Keywords: Corporate social responsibility; sustainability; leadership; behavioural competency; leadership development Paper type: Research paper
    • Belief–logic conflict resolution in syllogistic reasoning: Inspection-time evidence for a parallel-process model

      Stupple, Edward J. N.; Ball, Linden J.; University of Derby (Taylor and Francis, 2008-04-29)
      An experiment is reported examining dual-process models of belief bias in syllogistic reasoning using a problem complexity manipulation and an inspection-time method to monitor processing latencies for premises and conclusions. Endorsement rates indicated increased belief bias on complex problems, a finding that runs counter to the “belief-first” selective scrutiny model, but which is consistent with other theories, including “reasoning-first” and “parallel-process” models. Inspection-time data revealed a number of effects that, again, arbitrated against the selective scrutiny model. The most striking inspection-time result was an interaction between logic and belief on premise-processing times, whereby belief – logic conflict problems promoted increased latencies relative to non-conflict problems. This finding challenges belief-first and reasoning-first models, but is directly predicted by parallel-process models, which assume that the outputs of simultaneous heuristic and analytic processing streams lead to an awareness of belief – logic conflicts than then require time-consuming resolution.
    • Beneficial long-term antidiabetic actions of N- and C-terminally modified analogues of apelin-13 in diet-induced obese diabetic mice.

      Parthsarathy, Vadivel; Hogg, Christopher; Flatt, Peter R.; O'Harte, Finbarr P. M. (Wiley, 2017-07-20)
      AimsThis study investigated the chronic effects of twice daily administration of stable apelin analogues, apelin-13 amide and (pGlu)apelin-13 amide, on metabolic parameters in glucose intolerant and insulin resistant diet-induced obese (DIO) mice fed a high-fat diet for 150 days.Study Design & MethodsGroups of mice received twice daily (09:00 and 17:00 h) injections of saline vehicle, apelin-13 amide, (pGlu)apelin-13 amide or exendin-4(1–39) for 28 days (all at 25 nmol/kg). Energy intake, body weight, non-fasting blood glucose, plasma insulin, glucose tolerance, metabolic response to feeding and insulin sensitivity together with pancreatic hormone content and biochemical parameters such as lipids and total GLP-1 were monitored. Dual-energy X-ray absorptiometry (DXA) analysis and indirect calorimetry were also performed.ResultsAdministration of apelin-13 amide, (pGlu)apelin-13 amide or exendin-4 significantly decreased bodyweight, food intake, blood glucose and increased plasma insulin compared with high-fat fed saline treated controls (P < 0.05 and P < 0.001), Additionally, all peptide treated groups exhibited improved glucose tolerance (oral and ip), metabolic responses to feeding and associated insulin secretion. (pGlu)apelin-13 amide also significantly improved HbA1c and insulin sensitivity after 28 days. Both (pGlu)apelin-13 amide and exendin-4 increased bone mineral content and decreased respiratory exchange ratio (RER), whereas only (pGlu)apelin-13 amide increased energy expenditure. All treatment groups displayed reduced circulating triglycerides and increased GLP-1 concentrations, although only (pGlu)apelin-13 amide significantly reduced LDL-cholesterol, total body fat, and increased pancreatic insulin content.ConclusionThese data indicate the therapeutic potential of stable apelin-13 analogues with effects equivalent to or better than exendin-4.

    • Best supply chain management practices and high- performance firms: the case of Gulf manufacturing firms.

      AL-Shboul, Moh’d Anwer; Garza-Reyes, Jose Arturo; Kumar, Vikas; University of Derby; German-Jordanian University; University of West of England (Emerald, 2018-10)
      Purpose – The study aims to investigate the best supply chain management practices that are implemented in medium and large-sized Gulf manufacturing firms. Design/methodology/approach – This study has explored seven supply chain management practices, i.e. supplier collaboration, flexibility with partners, usage of Internet, customer focus, lean production, Internal integration, and quality management. It assumes that the best performing firms must be the ones implementing the best practices. T-test and multiple linear regression analyses were used to establish the best practices, implemented by medium and large-sized Gulf manufacturing firms. Findings – The results showed that quality management, customer focus, and supplier collaboration are considered as best supply chain management practices in Gulf manufacturing firms. Usage of internet may have been the best practice previously, but not anymore. Lean production cannot yet be qualified as, but may develop into the best supply chain management practice. Practical Implications – The study provides a useful contribution to the field of best supply chain management practices as it provides better decision-making insights and a benchmarking base to top managers, policy makers, and academics. It is likely to result in increased overall performance of their firms. Originality/value – The study provides an understanding of the distinctive characteristics of the best supply chain management practices, implemented by Gulf manufacturing firms. It has broader implications for all manufacturing firms, particularly in developing economies where the growth of manufacturing and effective management of their supply chains is a key element for the economic development.
    • Between excess and subtraction: Scenographic violence in Howard Barker’s Found in the Ground

      Kipp, Lara Maleen; University of Derby (Centre de recherche VALE, 23/06/2017)
      The article examines the violence produced by the scenography of Howard Barker's Found in the Ground, which emerges out of the play’s formal experimentation. Thematically, the play is rife with violence, such as former Nuremberg judge Toonelhuis’ consumption of the remains of high-ranking Nazis he sentenced to death, the continuous burning of books and the retelling of various murders by the war criminal Knox. Found in the Ground re-visions the collective European memory of the Holocaust; this thematic violence is expanded and subverted by scenographic means, radically reimagining the historical context. The particularity of the spatio-temporal, audio-visual rendering of violence in Barker’s text is the focus of this article. The article relates the play to Artaud’s conception of cruelty and to Lyotard’s thinking on the sublime. It contextualises the play through Barker’s theoretical writings, Lingis’ notion of catastrophic time (2000) and Aronson’s proposition of the stage as an abyss (2005).
