Proactive environmental management and performance by a controlling family
Authors: Huang Yi-Chun , Wong Ying-Jiuan , Yang Min-Li 
Published: February 2014

Purpose– This study examined how proactive environmental management affects firm performance and whether a controlling family moderates this effect. The paper aims to discuss these issues.Design/methodology/approach– The study adopted content analysis to collect data on listed Taiwanese firms and used cross-sectional regression analysis to examine the relationship between proactive environmental management and firm performance as well as the moderating role of a controlling family.Findings– The results indicated that not all types of proactive environmental management are positively associated with firm performance and that a controlling family might be more effective in low-risk proactive environmental management practices.Research limitations/implications– The focus was on the impact of proactive environmental management from the perspective of stockholders. Future research could investigate its impact on other stakeholders as well.Practical implications– The findings might convince managers that the stereotype of an environment-friendly firm – that the more its green initiatives, the less competitive it becomes – may not necessarily be true. Investing in product-focused pollution prevention could increase revenues and improve performance. Even though process-focused pollution prevention is negatively associated with firm performance, companies are not expected to reduce investment in green processes since they are required for the production of environment-friendly products.Originality/value– This study adopted a multi-dimensional approach to reveal how different types of proactive environmental management affect firm performance. The authors used the controlling family as a moderating variable to determine whether it moderates the relationship between proactive environmental management and firm performance.

Authors: E. Sekerka Leslie , Stimel Derek 
Published: February 2014

Purpose– This article aims to draw insight from a variety of management disciplines to encourage a broader view of the economy as it relates to sustainable waste management (SWM) development.Design/methodology/approach– The paper presents a framework to describe how strengths can be blended to support environmental sustainability (ES), highlighting the need for community cooperation between the informal and formal sectors of the economy.Findings– Unique contributions for SWM can emerge from both economic sectors and, when leveraged, may drive community development within local municipalities.Practical implications– The platform addresses the need for more flexible governmental policies that encourage waste management activities among formal and informal workers.Originality/value– The paper brings forward typically disregarded ES waste management opportunities that reside within the informal sector, an often overlooked aspect of the broader economy.
Personalized medicine in metastatic colorectal cancer treated with anti‐epidermal growth factor receptor agents: A future opportunity?
Authors: Tejpar Sabine , Piessevaux Hubert 
Published: February 2014

AbstractTreatment options for colorectal cancer have increased substantially in the past decade, with the introduction of novel biological therapies targeting cancer‐specific molecules leading to significantly improved outcomes. Despite access to these treatments, we are not yet in an era where we can fully personalize treatment choices for patients with colorectal cancer. A number of prognostic and predictive markers have been identified that appear to be directly related to sensitivity to targeted therapies, such as those against epidermal growth factor receptor. However, the sensitivities of individual tumors toward different biological agents appear to be more complex. It seems that a more complete molecular signature of the tumor must be taken into account when making individual treatment choices. In the absence of having fully elucidated the influence of these prognostic or predictive markers, other surrogate markers of early treatment success may be useful in determining whether to continue treatment with a particular agent. In this review, we discuss the role of molecular markers in choosing appropriate treatment for the individual patient, along with the use of measuring the depth of response to a particular agent to assist decisions on whether to continue therapy in colorectal cancer.
Executive Functioning and Mathematics Achievement
Authors: Bull Rebecca , Lee Kerry 
Published: February 2014

AbstractThe importance of executive functioning (EF) skills in mathematical achievement is well established, and researchers have moved from just measuring working memory or updating to an inclusion of other EF skills, namely, inhibition and shifting. In this article, we review studies that have taken different approaches to measuring EF (e.g., using single vs. multiple indicators) and those that have applied different analytical techniques to conceptualize the structure of EF (e.g., exploratory vs. confirmatory techniques). Across studies, updating is often a unique predictor of math achievement at many ages; the findings relating to inhibition and switching are less conclusive. We discuss these findings in relation to age‐related variance in EF structure, the nature of inhibitory and shifting task requirements, and the role of updating as a limiting factor or a common resource for inhibition and shifting.
Putting models to a good use: a rapid assessment of Arctic seabird biodiversity indicates potential conflicts with shipping lanes and human activity
Authors: Humphries Grant R. W. , Huettmann Falk 
Published: February 2014

AbstractAimsTo use open access models of predicted seabird distribution data in the Arctic to create rapid assessment biodiversity maps for management purposes and for prioritization of conservation.LocationHigh Arctic, North of 60° latitude.MethodsThe predicted distributions of 27 species of Arctic seabirds were combined to create a seabird biodiversity map. The GIS layers created were based on peer‐reviewed model outputs which were calculated using the random forest algorithm and supplemented with ISO standardized metadata for quality assurance. We have overlain the species diversity and occurrence maps with known shipping lanes and areas of human activities in the Arctic to highlight areas of potential human conflict with pelagic seabirds.ResultsEntry points to the Arctic Basin for example Baffin Bay, Davis Strait, Chukchi Sea, Greenland Sea and Norwegian Sea are specific conflict zones with mean number of species occurring within 20 km of shipping zones ranging from 17 to 19 (63–70% of modelled species). We also show that these are areas of the highest intensity of human activities in the Arctic (fishing, ship traffic and accident rates).Main conclusionThese Arctic seabird biodiversity maps can be used to make decisions which take into account ecology and socio‐economy (e.g. Marxan analysis and marine protected areas MPAs) and for ecological/economic studies which can help to create a pro‐active management scheme. This is particularly important due to the future increase in human impacts in the Arctic (i.e. fishing, tourism and especially shipping). By improving upon these models and further examination into the interactions between seabirds and humans in the Arctic, we can guide important policy decisions to protect Arctic biodiversity.
Comparative polyphenolic antioxidant profile and quality of traditional apple cultivars as affected by cold storage

Published: February 2014

Summary‘Kathista’ and ‘Lortiko’ are regarded as traditional and highly appreciated apple cultivars in Cyprus, yet their postharvest behaviour and phytochemical content are largely unknown. Such fruits were examined for their qualitative traits, phenolic composition and antioxidant capacity after harvest or short, intermediate or extended cold storage and additional ripening at room temperature (RT), using ‘Gala’ as reference cultivar. Total phenolic content was dependent on cultivar and length of cold storage, while hydroxycinnamic acids were always at higher levels compared to total flavonols for all the examined cultivars. No clear trends regarding the influence of cold storage or RT maintenance on fruit antioxidant properties were evident. Overall, quality attributes and polyphenolic content of the traditional apple cultivars were comparable with ‘Gala’ at harvest; thus, they can be considered a good source of nutraceuticals as summer apple cultivars. However, extended cold storage deteriorates fruit behaviour and antioxidant capacity, particularly in ‘Lortiko’ fruit.
Desensitization for solid organ and hematopoietic stem cell transplantation
Authors: Zachary Andrea A. , Leffell Mary S. 
Published: February 2014

SummaryDesensitization protocols are being used worldwide to enable kidney transplantation across immunologic barriers, i.e. antibody to donor HLA or ABO antigens, which were once thought to be absolute contraindications to transplantation. Desensitization protocols are also being applied to permit transplantation of HLA mismatched hematopoietic stem cells to patients with antibody to donor HLA, to enhance the opportunity for transplantation of non‐renal organs, and to treat antibody‐mediated rejection. Although desensitization for organ transplantation carries an increased risk of antibody‐mediated rejection, ultimately these transplants extend and enhance the quality of life for solid organ recipients, and desensitization that permits transplantation of hematopoietic stem cells is life saving for patients with limited donor options. Complex patient factors and variability in treatment protocols have made it difficult to identify, precisely, the mechanisms underlying the downregulation of donor‐specific antibodies. The mechanisms underlying desensitization may differ among the various protocols in use, although there are likely to be some common features. However, it is likely that desensitization achieves a sort of immune detente by first reducing the immunologic barrier and then by creating an environment in which an autoregulatory process restricts the immune response to the allograft.

Published: February 2014

BackgroundYoung Chilean women between 18 and 24 years of age are at high risk of contracting sexually transmitted infection (STI) and human immunodeficiency virus (HIV). The literature shows a shortage of STI–HIV prevention interventions focused on this specific high‐risk population and a unique set of barriers to receiving prevention messages. Internet‐based interventions are promising for delivering STI–HIV prevention interventions and avoiding barriers to services.AimsThe study aimed to develop a culturally informed Internet‐based STI–HIV prevention intervention for Chilean women between 18 and 24 years of age, to investigate its feasibility and acceptability, and to compile recommendations on what would make the intervention more acceptable and feasible for these women.MethodsThe development of the Internet intervention was facilitated by a process that featured consultation with content and technology experts. A pre‐post test design was used to test the acceptability and feasibility of the intervention with 40 young Chilean women between 18 and 24 years of age.ResultsThe intervention website consisted of four modules of content and activities that support learning. The intervention was feasible and acceptable for young Chilean women between 18 and 24 years of age.Discussion and conclusionThis study demonstrated the value of engaging multiple expert panels to develop culturally informed and technology‐based interventions. The results of this study support the feasibility and acceptability of conducting an Internet‐based intervention with multiple sessions, yielding high participation rates in a population in which there are barriers to discussion of STI–HIV prevention and sex‐related content.Implications for nursing and health policyThe outcomes have implications for nursing education and clinical practice and they can be used for the legal and judicial systems to promote or reinforce policies that encourage STI–HIV prevention strategies among women.
Session 2: Facing complexity

Published: February 2014

The second session addresses highly complex issues, from transforming energy consumers into producers of electricity, to modifying the nature of pharmaceutical trials. Ethnographers not only face change in social organisations, but in how to do research.All the papers in this session report studies address highly complex issues, from transforming energy consumers into producers of electricity, to modifying the nature of pharmaceutical trials. The complexity that ethnographers face is not just in the elaborate social organisations they have to immerse themselves, which has always been a characteristic of ethnography, it is in the task that the research is to accomplish. All the projects aim towards a massive transformation of practices which have in common a significant increase in users’ participation and responsibility: in the relation to utilities and sustainable living, in the role patients and doctors play in health care. It is as though organisations at all levels have now assimilated the participatory philosophy of the WWW and are designing services that distribute part of their work and power onto their users. In this context the ethnographic practitioner stops being an investigator of hidden needs and expectations, but is asked to reveal the agents of change, the triggers of transformation. Yet another challenge for the profession
Session 5: The state of our union: Reflections and projections on ethnography and ethnographers
Authors: COTTON MARTHA 
Published: February 2014

The last session reflects on EPIC's communal growth from interactions – some serendipitous others purposeful – with other disciplines. This session examines where practitioners are on this maturity trajectory: what it is like, as a community of practioners, to be where we are now, and where we are likely going.EPIC is in its 9th glorious year. Throughout the brief yet robust history of this annual community gathering we've been on a trajectory that charts our growing maturity as a group of professionals. We started with pangs of identity (Who are we? Who is one of us? Who is not?), which we thankfully discarded after a year or so and moved on to discussions of our relevance within the businesses we hope to impact. And as we grow and find new and exciting collaborators (Big data! Social enterprise! Business schools!), topics at EPIC shift to expanding that impact and understanding what these collaborations mean for the continued development of our praxis. As we've grown, we've made mistakes, but have learned from them. As we've grown, we've benefited from serendipitous interactions with other disciplines, but we have worked to make these interactions more purposeful. After all, that's what maturity is all about! This paper session is about examining where we are on this maturity trajectory: reflections on what it is like, as a community of practioners, to be where we are now. Asking what can we learn when we examine where we are now? And what this might mean for where we are going?
Physiological traits suggest limited diapause response in false codling moth, Thaumatotibia leucotreta (Lepidoptera: Tortricidae)
Authors: Terblanche J. S. , de Jager Z. , Boardman L. , Addison P. 
Published: February 2014

AbstractThe ability of a pest insect species to enter diapause, a physiological state of dormancy, has significant implications for population dynamics and pest management practises in agricultural landscapes. The false codling moth Thaumatotibia leucotreta is a major pest of deciduous and citrus fruit in southern Africa and a quarantine pest of international concern. Apart from an early field assessment that may have been compromised by taxonomic uncertainty surrounding cryptic developing life stages, no studies have investigated diapause induction within an experimental framework for this species, and none to date have used a suite of physiological traits potentially indicative of the diapause state. Here, we subjected larvae to cooling and shortening day length over a period of 14 days [Diapause Treatment (DT) group] relative to a similar‐aged control (CON) group held at optimal rearing conditions (25°C, 12 : 12 L : D) and tested if physiological traits, including resting metabolic rate, body freezing temperature (=supercooling point, equivalent to the low‐temperature mortality threshold) and body condition (body mass, body lipid and water content) varied in a direction that may be reflective of diapause induction. Mean metabolic rate in DT larvae was 0.044 ml CO2/h (mean mass: 52.7 mg), which was significantly higher than in CON larvae [0.025 ml CO2/h, mean mass: 51.5 mg (P = 0.04)]. Supercooling points were not statistically lower in the CON group than in DT larvae (DT:−15.6 ± 1.5°C; CON: −16.4 ± 2.8°C; P = 0.33). Measures of body size, body condition and resting water loss rates remained similar between groups. These results support the conclusion of early field observations that T. leucotreta does not undergo diapause that has significant implications for the management of the species.
Is there an associational resistance of winter pea–durum wheat intercrops towards Acyrthosiphon pisum Harris?

AbstractAcyrthosiphon pisum Harris (Aphididae: Hemiptera), the pea aphid, is an important pest in organic farming systems. In this work, the objective was to gather empirical field data on the associational resistance of durum wheat–winter pea intercrops towards the pea aphid, compared with pure stands of winter pea. Our results showed that intercropping winter pea with durum wheat significantly decreased A. pisum abundance in all the situations. Moreover, it was systematically observed that pea grew bigger in pure than in intercropped stands but after considering pea dry mass as a covariate, it appeared that the durum wheat–winter pea intercrop was still significantly less attacked by pea aphids than the sole crop. Intercrop sowing designs had an incidence on infestation levels: substitutive diversification systems of different types are more effective in decreasing the level of aphid infestation than does the additive system. In addition, substitutive row intercrop is significantly less infested than substitutive mixture. These results suggest that a mechanism related to the resource concentration hypothesis may explain the associational resistance of the IC of durum wheat–winter pea towards A. pisum.
INTERPRETING SPATIAL ECONOMETRIC ORIGIN‐DESTINATION FLOW MODELS
Authors: LeSage James P. , Thomas‐Agnan Christine 
Published: February 2014

ABSTRACTSpatial interaction or gravity models have been used to model flows that take many forms, for example population migration, commodity flows, traffic flows, all of which reflect movements between origin and destination regions. We focus on how to interpret estimates from spatial autoregressive extensions to the conventional regression‐based gravity models that relax the assumption of independence between flows. These models proposed by LeSage and Pace (, ) define spatial dependence involving flows between regions. We show how to calculate partial derivative expressions for these models that can be used to quantify these various types of effect that arise from changes in the characteristics/explanatory variables of the model.

Summary

We used natural and tracer nitrogen (N) isotopes in a Pinus taeda free air CO2 enrichment (FACE) experiment to investigate functioning of ectomycorrhizal and saprotrophic fungi in N cycling.

Fungal sporocarps were sampled in 2004 (natural abundance and 15N tracer) and 2010 (tracer) and δ15N patterns were compared against litter and soil pools.

Ectomycorrhizal fungi with hydrophobic ectomycorrhizas (e.g. Cortinarius and Tricholoma) acquired N from the Oea horizon or deeper. Taxa with hydrophilic ectomycorrhizas acquired N from the Oi horizon (Russula and Lactarius) or deeper (Laccaria, Inocybe, and Amanita). 15N enrichment patterns for Cortinarius and Amanita in 2010 did not correspond to any measured bulk pool, suggesting that a persistent pool of active organic N supplied these two taxa. Saprotrophic fungi could be separated into those colonizing pine cones (Baeospora), wood, litter (Oi), and soil (Ramariopsis), with δ15N of taxa reflecting substrate differences. 15N enrichment between sources and sporocarps varied across taxa and contributed to δ15N patterns.

Natural abundance and 15N tracers proved useful for tracking N from different depths into fungal taxa, generally corresponded to literature estimates of fungal activity within soil profiles, and provided new insights into interpreting natural abundance δ15N patterns.
Number of Jordan blocks of the maximal size for local monodromies
Authors: Dimca Alexandru , Saito Morihiko 
Published: February 2014

AbstractWe prove formulas for the number of Jordan blocks of the maximal size for local monodromies of one-parameter degenerations of complex algebraic varieties where the bound of the size comes from the monodromy theorem. In the case when the general fibers are smooth and compact, the proof calculates some part of the weight spectral sequence of the limit mixed Hodge structure of Steenbrink. In the singular case, we can prove a similar formula for the monodromy on the cohomology with compact supports, but not on the usual cohomology. We also show that the number can really depend on the position of singular points in the embedded resolution, even in the isolated singularity case, and hence there are no simple combinatorial formulas using the embedded resolution in general.
