Published: November 2012

AbstractIn freshwater systems, parasitological studies have mainly been carried out on vertebrates and molluscs, but little is known about parasites of aquatic insects. We describe the trematodes and nematodes parasitizing the benthic insects of an Andean Patagonian stream and the presence of parasites in the terrestrial adult stages. Members of 3 of 20 insect taxa were found to be parasitized by larval nematodes, and members of six taxa harbored metacercariae of digeneans. In benthic samples, chironomids, simuliids (Order Diptera), and baetids (Order Ephemeroptera) harbored mermithid larvae (Nematoda). The stonefly Antarctoperla michaelseni (Order Plecoptera), the caddisfly Smicridea annulicornis (Order Trichoptera), a watersnipe fly (Order Diptera: Athericidae), and three species of leptophlebiid mayflies (Order Ephemeroptera) were parasitized by encysted plagiorchiid metacercariae (Order Plagiorchiida). Most metacercariae were found in the three species of mayflies with prevalences ranging 15–63% and mean intensities ranging 1.2–4.9. Prevalence declined from summer to early winter, probably because of the emergence of infected nymphs and the recruitment of uninfected new cohorts. The imagos had live metacercariae with higher prevalences and intensities of infection than nymphs. We suggest that these plagiorchiids have an allogenic life cycle, involving a terrestrial definitive host.
Predicting exercise adherence in cancer patients and survivors: a systematic review and meta‐analysis of motivational and behavioural factors

Published: November 2012

Aims and objectivesTo examine research findings regarding predictors of adherence to exercise programmes in cancer populations.BackgroundCancer patients are advised to participate in daily exercise. Whether they comply with the recommendations for physical activity or not remains unclear.DesignA systematic review and meta‐analysis.MethodsEmpirical articles published in English between 1995 and 2011 were searched in electronic databases and in reference lists, using the search terms ‘adherence’, ‘predictors’, ‘exercise’, and ‘cancer’ in varying combinations. Twelve of 541 screened abstracts met the inclusion criteria. The included studies' eligibility considering predictors of exercise adherence were reviewed. A quality assessment process evaluating the studies methodological quality was performed. Eight of the reviewed studies were considered eligible for a meta‐analysis involving Pearson's r correlations.ResultsExercise stage of change, derived from the transtheoretical model of behaviour change (TTM) was found to be statistically significant and a strong predictor of exercise adherence. In addition, the theory of planned behaviour (TPB) construct; intention to engage in a health‐changing behaviour and perceived behavioural control, demonstrated significant correlations with exercise adherence.ConclusionsThe review identified that both the TPB and the TTM frameworks include aspects that predicts exercise adherence in cancer patients, and thus contributes to the understanding of motivational factors of change in exercise behaviour in cancer populations. However, the strengths of predictions were relatively weak. More research is needed to identify predictors of greater importance.Relevance to clinical practiceSurveying the patients' readiness and intention to initiate and maintain exercise levels, as well as tailoring exercise programmes to individual needs may be important for nurses in order to help patients meet exercise guidelines and stay active.
A new genus and species of gall midge (Diptera: Cecidomyiidae) from Casuarina trees in Australia
Authors: Kolesik Peter , Brown Bradley T , Purcell Matthew F , Taylor Gary S 
Published: November 2012

AbstractA new species of gall midge, Ophelmodiplosis clavata Kolesik gen. et sp. nov., induces club‐like galls on branchlet tips of she‐oaks Casuarina glauca, C. equisetifolia and C. cunninghamiana in Australia. The presence of galls may possibly retard development of the male flower‐bearing branchlets and thus restrict sexual reproduction of the host plant. A new genus is erected to contain the new species. Ophelmodiplosis belongs to the supertribe Cecidomyiidi and its closest relative is Lophodiplosis Gagné, an Australian genus containing species that cause galls on leaves, stems and buds of Melaleuca trees. The new species is considered for biological control of C. glauca, C. equisetifolia and C. cunninghamiana, which are serious weeds in the coastal USA, including Florida, Hawaii and the Caribbean.
Value, Security and Temporality in Nietzsche's Critique of Modernity
Authors: Burgess J. Peter 
Published: November 2012

A certain pathos of temporality is at the core of Nietzsche's critique of reason, and it is this pathos that motivates his questioning of the Western discourse of values and of valuation. The well-rehearsed Nietzschean thesis about the decline of values in modernity – nihilism as a kind of character fault of the modern personality –builds in effect less upon the values themselves (whatever these might be specified as) than upon a certain evolution in the human subject. An evolution in the subjectivity that has turned humans around from what Giddens (perhaps misleadingly) called ontological security towards their evolving capacity to navigate an unknown future and negotiate the values that flow from it. This article tries to demonstrate how Nietzsche's notion of modern subjectivity is in this sense inseparable from our negotiation of values over time; inseparable, in other words, from a certain axiology of time. Critically, it is not nihilism that is Nietzsche's primary concern – as so many read him – but rather his notion that values are inhabited by their own contingency: namely, the very possibility of their own exhaustion. For Nietzsche, the critique of morality is a particular case of his critique of values. All evaluation, all practices of conceptualizing, determining and applying values fits into the kind of genealogy Nietzsche carries out on morality. For Nietzsche there is an inseparable link between the supposed essence of value and the temporal field in which their rise or decline is experienced, and bemoaned.
Confined Mobilities: Following Indonesian Migrant Workers on Their Way Home
Authors: Kloppenburg Sanneke , Peters Peter 
Published: November 2012

AbstractThis paper examines the return journeys of Indonesian migrant domestic workers to their home towns. When migrant workers return home, the Indonesian government sets them apart from other travellers in order to protect the migrants from extortion in the airport environment, and assist them during their return to their home villages. We investigate how this separate passage results in a mobility regime that produces differences between regular travellers and migrant worker travellers, and between male and female migrant workers. We also examine how the mobility regime results in particular forms of control over and safety of migrant workers' mobility. In doing so, we argue that the politics of mobility not only can be studied at the scale of global circuits, or at nodes such as the workplace, but also in relation to the actual journeys that migrant workers make.
Artists‐Accompanied Urban Regeneration: Insights and Lessons from Utrecht and Rotterdam
Authors: Zebracki Martin , Smulders Lévi 
Published: November 2012

AbstractUrban regeneration in Dutch cities is increasingly accompanied by the cultural sector in general and by artists in particular. This paper presents comparative case studies on current artists‐accompanied urban regeneration initiated by housing corporations in Utrecht and Rotterdam. On the basis of discourse analysis on the voices of decisive actors, it explores the rationale behind artists‐accompanied urban regeneration and the sociospatial implications thereof. It empirically indicates that housing corporations are more inclined to deploy artists in urban regeneration when there are sufficient vacant buildings. It also illustrates that more decentralised housing corporations have a stronger and more long‐term commitment to urban regeneration. The latter includes a greater commitment to interventions by artists within urban public space.

ObjectiveTo determine the influence of conventional nonlocked application of surgeon‐contoured (NL‐SXc) and locked‐hybrid application of precontoured (L‐Pc)‐ TPLO plates on the tibial plateau angle (TPA) immediately postoperatively and longterm after tibial plateau leveling osteotomy (TPLO) in dogs as well as to evaluate their influence on the incidence of intra‐articular screw placement and bone healing.Study DesignRetrospective, cross‐sectional, clinical study.AnimalsDogs (n = 101) with cruciate ligament insufficiency that had TPLO.MethodsCollected data included signalment, plate size/type, preoperative (PreTPA), postoperative (PostTPA), and recheck TPA (ReTPA). Tibial plateau rotation achieved during surgery (RotaTPA = PreTPA‐PostTPA) and TPA shift during healing (ShiftTPA = ReTPA‐PostTPA) were calculated. Radiographic evidence of stability and time to radiographic recheck were recorded. Variables were compared by plate type using a 2‐sample t‐test or χ2 as appropriate (significance at P < .05).ResultsMedian time to radiographic follow‐up was 75 days (range, 43–2815 days). The remaining data are reported as means. Forty‐two stifles had NL‐SXc, 59 stifles had L‐Pc. PreTPA of NL‐SXc and L‐Pc was 28.3° and 29.1°, respectively (P = .22). PostTPA (13.2° and 7.9°), RotaTPA (15.0° and 21.2°) and ReTPA (14.9° and 10.3°) for NL‐SXc and L‐Pc, respectively, were all significantly different (P< .0001). ShiftTPA for these constructs (1.7° and 2.4°, respectively) was not significantly different (P = .25), and 92.1% of dogs were considered to have radiographically stable osteotomies at last recheck.ConclusionsA higher degree of tibial plateau rotation was achieved and maintained in osteotomies with L‐Pc. There was no significant difference in ShiftTPA or radiographic osteotomy stability between constructs.
On the Relative Pricing of Long‐Maturity Index Options and Collateralized Debt Obligations
Authors: COLLIN‐DUFRESNE PIERRE , GOLDSTEIN ROBERT S. , YANG FAN 
Published: November 2012

ABSTRACTWe investigate a structural model of market and firm‐level dynamics in order to jointly price long‐dated S&P 500 index options and CDO tranches of corporate debt. We identify market dynamics from index option prices and idiosyncratic dynamics from the term structure of credit spreads. We find that all tranches can be well priced out‐of‐sample before the crisis. During the crisis, however, our model can capture senior tranche prices only if we allow for the possibility of a catastrophic jump. Thus, senior tranches are nonredundant assets that provide a unique window into the pricing of catastrophic risk.
Strategic Default and Equity Risk Across Countries
Authors: FAVARA GIOVANNI , SCHROTH ENRIQUE , VALTA PHILIP 
Published: November 2012

ABSTRACTWe show that the prospect of a debt renegotiation favorable to shareholders reduces the firm's equity risk. Equity beta and return volatility are lower in countries where the bankruptcy code favors debt renegotiations and for firms with more shareholder bargaining power relative to debt holders. These relations weaken as the country's insolvency procedure favors liquidations over renegotiations. In the limit, when debt contracts cannot be renegotiated, equity risk is independent of shareholders' incentives to default strategically. We argue that these findings support the hypothesis that the threat of strategic default can reduce the firm's equity risk.
Dynamic Agency and the q Theory of Investment
Authors: DEMARZO PETER M. , FISHMAN MICHAEL J. , HE ZHIGUO , WANG NENG 
Published: November 2012

ABSTRACTWe develop an analytically tractable model integrating dynamic investment theory with dynamic optimal incentive contracting, thereby endogenizing financing constraints. Incentive contracting generates a history‐dependent wedge between marginal and average q, and both vary over time as good (bad) performance relaxes (tightens) financing constraints. Financial slack, not cash flow, is the appropriate proxy for financing constraints. Investment decreases with idiosyncratic risk, and is positively correlated with past profits, past investment, and managerial compensation even with time‐invariant investment opportunities. Optimal contracting involves deferred compensation, possible termination, and compensation that depends on exogenous observable persistent profitability shocks, effectively paying managers for luck.

Published: November 2012

AbstractParticipative processes and citizens’ empowerment are considered crucial aspects of social innovation (SI), involving collaborative activities between the private, public, and third sectors. This article discusses the principal trends in the literature on the concept ofSI, its aims and differential characteristics related to the identification of people's needs, citizen participation processes, and improved quality of life. We present an exploratory case study ofSIfocusing on the gap between elderly people's needs and the generation of business opportunities, using a living lab (LL) methodology for collaborative placed‐based innovation. Our results suggest thatLLs are a useful instrument to detect community needs and improve local development and support and integrate technological and social innovations in policies and local governance processes.
Bridging Access to Electricity Through BOP Markets: Between Economic Equations and Political Configurations

Published: November 2012

AbstractThe development of markets for the poorest populations (Base of the Pyramid [BOP]) has become important for multinational companies (MNCs), nongovernmental organizations, and public policies. Assuming that there is demand for very low price consumer products and that the main problem is one of access to those products, the challenge for MNCs is to reconfigure the whole of the corporate process accordingly. The article follows BOP theory and companies' actual innovation. It looks at the definitions of the BOP market, the representation of BOP consumers, and local heterogeneous configurations of actors. Based on fieldwork with an MNC (specializing in electrical equipment) investigating a BOP business, it investigates the work undertaken by managers to build this market innovation. It explores the paradoxical frontiers of consumption and aid to the poorest populations and feeds the reflexion of BOP policies by opening it up toward a diversity of alternatives and possible configurations.
Carotid Artery Dissection due to Elongated Styloid Process: A Self‐Stabbing Phenomenon
Authors: Razak Anmar , Short Jody L. , Hussain Syed I. 
Published: November 2012

ABSTRACTElongated styloid process (ESP) is an anatomical variant that has been described as the cause of Eagle syndrome. Until recently, the styloid process has not been appreciated as a significant contributor to carotid artery dissection (CAD), which is not part of Eagle syndrome. We present a case of a 41‐year‐old male who presented with acute right middle cerebral artery occlusion and was found to have ESP projecting to and abutting the lateral wall of a dissected right internal carotid artery (ICA). Forced sustained head turning with maximal muscle contraction was the initiating event driving the styloid process into the wall of the ICA in a manner that can be likened to being stabbed with a pointed object. Knowing the association between ESP, Eagle syndrome, and CAD shall lead to increased awareness and appropriate diagnosis and treatment.
Coinage of the Term Environment: A Word Without Authority and Carlyle’s Displacement of the Mechanical Metaphor
Authors: Jessop Ralph 
Published: November 2012

AbstractTranslating the word ‘Umgebung’ in a work by Goethe, Carlyle coined the term ‘environment’ in the South of Scotland in 1828. Goethe’s usage involves reference to a Scottish subject, Macpherson’s Ossian. Referring to this, in 1942 Spitzer argued that the broader meaning of the word was misrepresented by Carlyle’s translation. However, after coining the term environment, Carlyle’s later work can be read as a significant realisation of this broader Goethean meaning, through his literary‐critical discussion of Robert Burns, literary‐philosophical Sartor Resartus, and his biography and historiography. The term needs to be seen partly as a response to a large number of intersecting social, political, economic, and agrarian changes associated with the Enlightenment, the industrial revolution, and in particular the modernising transformations of the Lowland Clearances. But, through the ways in which this examination of the term’s coinage brings into relation Goethe, Carlyle, the philosophy of Thomas Reid, and a theory of concepts by Sir William Hamilton, the hybridising processes involved in coining the term can also be seen as constituting a pivotal moment of transnational cultural exchange, an encapsulation of diversity, an interdisciplinary interrelation of literary, philosophical, and social critique, and a paradigm‐shifting challenge to the authority of mechanism. These intersecting elements are peculiarly apt with regard to certain radical dimensions of continuing relevance to the counter‐Enlightenment position of Adorno and Horkheimer, humanity’s relation with nature, our continuing struggles with the Enlightenment legacy, and to the expansive, plural, and potentially evolving character of the notion of environment – but also to the later emergence of environmentalism.
Constance Naden’s Philosophical Poetry
Authors: Alarabi Nour 
Published: November 2012

AbstractThe recent movement to revise and revive the works of nineteenth‐century women poets had led to the rediscovery of the works of a Victorian botanist, geologist, philosopher, poet and atheist Constance Caroline Woodhill Naden. Most contemporary readings of Naden’s poetry are based on a feminist approach. This sometimes leads to regarding the philosophy that lied behind composing them as complementary to what is considered to be the main topic of her poetry: the position of a Victorian woman poet and philosopher in patriarchal nineteenth‐century England. Naden’s poetic legacy consists of only two collections of poems. Despite the fact that she completely stopped writing poetry in the year 1886 to dedicate herself fully to philosophical pursuits, her verses, however, suggest that composing poetry was not merely a pastime activity. Although it ranked second to science and philosophy, she still used her poetry in many instances to spread philosophical and scientific awareness in the face of religious beliefs and superstitions. This article aims to illustrate the eminence of philosophy, especially Naden’s own theory of Hylo‐Idealism, in her poetry, and the significant role her poetry played towards achieving Naden’s ultimate goal of illuminating the minds of Victorian women as well as men.
Chemical Optimization of Protein Extraction from Sweet Potato (Ipomoea batatas) Peel
Authors: Maloney Katherine P. , Truong Van‐Den , Allen Jonathan C. 
Published: November 2012

Abstract:  Proteins isolated from sweet potatoes (Ipomoea batatas) have been shown to possess antidiabetic, antioxidant, and antiproliferative properties. The objective of this study was to chemically optimize a process for extracting proteins from sweet potato peel. The extraction procedure involved mixing peel with saline solvent to dissolve proteins and then precipitating with CaCl2. Quadratic and segmented models were used to determine the optimum NaCl concentration and peel to solvent ratio to maximize protein solubility while minimizing solvent usage. A segmented model was also used to optimize the concentration of CaCl2 used for precipitation. The highest yield was obtained by mixing blanched peelings with 59.7 mL of 0.025 mM NaCl per g peel and then precipitating with 6.8 mM CaCl2. The results of this study show that potentially valuable proteins can be extracted from peel generated during processing of sweet potatoes and industrial costs can be minimized by using these optimum conditions.Practical Application:  Potentially valuable proteins can be extracted from sweet potato peel, a waste product of sweet potato processing.
Emerging Role of the Ubiquitin Proteasome System in the Control of Shoot Apical Meristem FunctionF
Authors: Di Giacomo Elisabetta , Serino Giovanna , Frugis Giovanna 
Published: November 2012

AbstractThe shoot apical meristem (SAM) is a population of undifferentiated cells at the tip of the shoot axis that establishes early during plant embryogenesis and gives rise to all shoot organs throughout the plant's life. A plethora of different families of transcription factors (TFs) play a key role in establishing the equilibrium between cell differentiation and stem cell maintenance in the SAM. Fine tuning of these regulatory proteins is crucial for a proper and fast SAM response to environmental and hormonal cues, and for development progression. One effective way to rapidly inactivate TFs involves regulated proteolysis by the ubiquitin/26S proteasome system (UPS). However, a possible role of UPS‐dependent protein degradation in the regulation of key SAM TFs has not been thoroughly investigated. Here, we summarize recent evidence supporting a role for the UPS in SAM maintenance and function. We integrate this survey with an in silico analysis of publicly‐available microarray databases which identified ubiquitin ligases that are expressed in specific areas within the SAM, suggesting that they may regulate or act downstream of meristem‐specific factors.

Identification of SUMO Targets by a Novel Proteomic Approach in PlantsF
Authors: López‐Torrejón Gema , Guerra Davide , Catalá Rafael , Salinas Julio , del Pozo Juan C. 
Published: November 2012

AbstractPost‐translational modifications (PTMs) chemically and physically alter the properties of proteins, including their folding, subcellular localization, stability, activity, and consequently their function. In spite of their relevance, studies on PTMs in plants are still limited. Small Ubiquitin‐like Modifier (SUMO) modification regulates several biological processes by affecting protein‐protein interactions, or changing the subcellular localizations of the target proteins. Here, we describe a novel proteomic approach to identify SUMO targets that combines 2‐D liquid chromatography, immunodetection, and mass spectrometry (MS) analyses. We have applied this approach to identify nuclear SUMO targets in response to heat shock. Using a bacterial SUMOylation system, we validated that some of the targets identified here are, in fact, labeled with SUMO1. Interestingly, we found that GIGANTEA (GI), a photoperiodic‐pathway protein, is modified with SUMO in response to heat shock both in vitro and in vivo.
