Ecological genetics and evolution in insect pests: Implications for lower input agriculture
Authors: Simms Ellen L. 
Published: October 2009

AbstractThis paper has three goals: (1) to convince ecologists and evolutionary biologists to study the evolution in insects of the ability to overcome crop protection measures, (2) to provide insights into the kinds of data needed to develop methods for retarding the evolution of such traits, and (3) to suggest that the study of these phenomena can further our understanding of evolution. The evolution of resistance to chemical insecticides often results in higher application rates and constant development of new classes of these potentially environmentally degrading toxicants. Moreover, it is important to understand resistance phenomena related to alternative crop protection measures involving plant genetic resistance and biological insecticides so that these less environmentally damaging control measures can be maintained. Insecticide resistance evolves in insect populations in response to selection by chemical compounds. Similarly, selection by host-plant defenses of resistant crops leads to the evolution of virulence to those varieties. The evolution of these traits constitutes an important subject of applied evolutionary biology. In the context of single-gene evolutionary models, this article reviews the most common strategies that have been suggested for retarding the evolution of insecticide resistance. These models are also used to illustrate the effects of ecological factors and genetical properties of insect populations on the evolution of resistance. Where appropriate, the relevance of these models to the evolution of virulence to resistant crop varieties is also described. Durability in the insecticidal effectiveness of a plant protective chemical is not incompatible with the requirement for health safety in the same material.
Strategies for research and management in reduced-input agroecosystems
Authors: Hendrix Paul F. 
Published: October 2009

AbstractDeveloping reduced-input agroecosystems is a challenge to researchers and practitioners in a number of disciplines. In particular, because of the complexity of managerial inputs, understanding the effects of decreases in levels of one or several inputs presents a difficult experimental problem. Moderate reductionism is proposed as an appropriate hierarchical analysis, which first characterizes system level behavior and then explains it in terms of system components and their interactions. An example is given using reduced nitrogen fertilizer inputs; higher nitrogen use efficiency at lower levels of input is explained by increased nutrient recycling between soil and plant subsystems. Transition from conventional to reduced-input management involves changes in both economic and ecological properties of agroecosystems. Biological, chemical and physical changes, including increased species diversity, tighter nutrient recycling, and longer-term perennial effects, may parallel ecological succession. Hypothetical trends for several such changes are discussed.
Medical advertising and trust in late Georgian England
Authors: BARKER HANNAH 
Published: October 2009

ABSTRACT:This article explores the nature of trust in the fast growing and rapidly changing urban environments of late eighteenth- and early nineteenth-century England through an examination of medical advertisements published in newspapers in Manchester, Liverpool, Leeds and Sheffield between 1760 and 1820. The ways in which medicines were promoted suggest not just a belief that the market in medicines operated both rationally and fairly, but also a conception that a trustworthy ‘public’ existed that was not limited to the social elite but was instead constituted of a more socially diverse range of individuals.
Urban planning, colonial doctrines and street naming in French Dakar and British Lagos,c.1850–1930
Authors: BIGON LIORA 
Published: October 2009

ABSTRACT:The published literature that has thoroughly treated the history of European planning in sub-Saharan Africa is still rather scanty. This article examines French and British colonial policies for town planning and street naming in Dakar and Lagos, their chieflieux de colonisationin West Africa. It will trace the relationships between the physical and conceptual aspects of town planning and the colonial doctrines that produced these plans from the official establishment of these cities as colonial capitals in the mid-nineteenth century and up to the inter-war period. Whereas in Dakar these aspects reflected a Eurocentric meta-narrative that excluded African histories and identities, a glimpse at contemporary Lagos shows the opposite. This study is one of few that compares colonial doctrines of assimilation to doctrines of indirect rule as each affects urban planning.
Industrial urbanization, working-class lads and slang toponyms in early twentieth-century Helsinki
Authors: PAUNONEN HEIKKI , VUOLTEENAHO JANI , AINIALA TERHI 
Published: October 2009

ABSTRACT:The article investigates the linkages between urban transformation and informal verbalizations of everyday spaces among male juveniles from Sörnäinen (a working-class district in Helsinki) in 1900–39. Sörkka lads' biographically and contextually varying uses of slang names mirrored their itineraries across the city in the search of earning and spare-time opportunities. As a simultaneously practical and stylistic street language, the uses of slang both eroded (in uniting bilingual male juvenile groups) and strengthened (as with providers and teachers, working-class girls, upper-class urbanites and rural newcomers) existing socio-spatial boundaries. Unlike in the late nineteenth century Stockholmska slang studied by Pred, openly irreverent toponymic expressions vis-à-vis the hegemonic conceptions of urban space were relatively few in early Helsinki slang.
Benefit-transfer valuation of a cultural heritage site: the Petroglyph National Monument
Authors: ULIBARRI CARLOS A. , ULIBARRI VICTOR C. 
Published: October 2009

ABSTRACTThis paper applies a household production framework (Becker, 1971) to infer the economic value of a cultural heritage site, namely, the Petroglyph National Monument, situated in Albuquerque, New Mexico, USA. The empirical analysis uses benefit-transfer techniques from three source studies: those of Bergstrom and Cordell (1991) and Boxallet al. (2003), which concern willingness-to-pay to hike and view rock art sites; and those of Rolfe and Windle (2003, 2006), which concern willingness-to-pay by Aboriginal and general populations to preserve a cultural heritage site containing rock art. The benefit-transfer analysis estimates recreational values between 3.75 million and 7 million dollars per year (depending on perceptions of the cultural attribute quality) and a nonuse value of approximately 12.5 million dollars per year. By comparison the annualized costs of developing/operating the study site are 8.5 million dollars per year. Thus a partial cost-benefit analysis suggests the study site yields net economic benefits upwards of 7.8 million dollars per year.
Japan's Parliamentary Confrontation on the Post-Cold War National Security Policies
Authors: SHINODA TOMOHITO 
Published: October 2009

AbstractIn the fall 2007 Diet session, the largest opposition Democratic Party of Japan (DPJ) showed strong opposition against the government's proposal to continue the Self-Defense Forces (SDF) refueling operations to support maritime inspections in the Indian Ocean. In order to evaluate this parliamentary confrontation, the article compares the handling of this issue with the six past major post-Cold War national security policies. The DPJ constantly presented its own legislative proposals in order to participate in Diet deliberation. DPJ's counter proposals, however, were not always cooperative with the government. This different attitude by the DPJ could not be explained by the public and media opinions or the position of the supporting organization but by DPJ's political calculation.

Objective.Intensive care units (ICUs) are potential high-risk areas for the transmission of respiratory viruses such as influenza. An influenza pandemic is expected to result in a dramatic surge of critically ill patients, and ICU healthcare workers (HCW) are likely to be at high risk of infection.Objective.To characterize the knowledge, attitudes, and expected behaviors of ICU HCWs concerning the risk of and response to an influenza pandemic.Design, Participants, and Setting.A survey was distributed to 292 HCWs (ie, internal medicine house staff, pulmonary and critical care fellows and faculty members, nurses, and respiratory care professionals) at 2 hospitals in Baltimore, Maryland.Results.Of the 292 HCWs, 256 (88%) completed the survey. Just over one-half of the respondents believed there is at least a 45% chance of an influenza pandemic within the next 5 years. However, only 41% reported knowing how to protect themselves during an outbreak. Despite this common belief that a pandemic is likely in the near future, 59% of those surveyed reported only minimal knowledge of the risks of and protective strategies for an influenza pandemic, and 20% reported being unlikely to report to work during a pandemic or being unsure about whether they would do so. The odds of reporting to work varied on the basis of race and responsibility for child care.Conclusions.ICU HCWs reported having minimal knowledge concerning the risk of and response to an influenza pandemic, even though more that one-half of HCWs expect that a pandemic will occur in the near future. This finding in a high-risk setting is of concern, given that lack of knowledge among HCWs may result in increased nosocomial transmission to HCWs and patients. Interventions to improve knowledge of pandemics and understanding of risks among ICU HCWs are essential.
The ubiquitin/26S proteasome system in plant–pathogen interactions: a never‐ending hide‐and‐seek game

Published: October 2009

SUMMARYThe ubiquitin/26S proteasome system (UPS) plays a central role in plant protein degradation. Over the past few years, the importance of this pathway in plant–pathogen interactions has been increasingly highlighted. UPS is involved in almost every step of the defence mechanisms in plants, regardless of the type of pathogen. In addition to its proteolytic activities, UPS, through its 20S RNase activity, may be part of a still unknown antiviral defence pathway. Strikingly, UPS is not only a weapon used by plants to defend themselves, but also a target for some pathogens that have evolved mechanisms to inhibit and/or use this system for their own purposes. This article attempts to summarize the current knowledge on UPS involvement in plant–microbe interactions, a complex scheme that illustrates the never‐ending arms race between hosts and microbes.
From concerned to convinced: reaching decisions about out‐of‐home care in Norwegian Child Welfare Services
Authors: Christiansen Øivin , Anderssen Norman 
Published: October 2009

ABSTRACTPlacing children in out‐of‐home care constitutes one of the strongest public interventions in families. This paper explores how Norwegian Child Welfare Service (CWS) workers present their reasons as well as their work processes in the course of deciding to place children in out‐of‐home care. The analysis is based on interviews with 83 social workers and concerns 109 children recently removed from their homes. Three central elements were identified in the social workers' accounts: (1) a description of worrying conditions in the family; (2) the workers' long‐term back‐and‐forth process, which revolved around experiences from the case, particularly around interactions with the parents; and (3) a triggering factor that made the out‐of‐home placement take place when it did. These elements underline the need to include both substance (conditions related to the child and his/her family) and procedure (conditions related to the work on the case) to understand what leads CWS to removing children. Both types of conditions put the parents, rather than the children, in the centre of the workers' attention, which may be explained by the position and role of the CWS workers as street‐level bureaucrats. The findings emphasize the importance of acknowledging the contradictory position of CWS workers.
Clinical applications of intravenous immunoglobulins in neurology

Published: October 2009

Summary
Intravenous immunoglobulin (IVIg) is used increasingly in the management of patients with neurological conditions. The efficacy and safety of IVIg treatment in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and Guillain–Barré syndrome (GBS) have been established clearly in randomized controlled trials and summarized in Cochrane systematic reviews. However, questions remain regarding the dose, timing and duration of IVIg treatment in both disorders. Reports about successful IVIg treatment in other neurological conditions exist, but its use remains investigational. IVIg has been shown to be efficacious as second-line therapy in patients with dermatomyositis and suggested to be of benefit in some patients with polymyositis. In patients with inclusion body myositis, IVIg was not shown to be effective. IVIg is also a treatment option in exacerbations of myasthenia gravis. Studies with IVIg in patients with Alzheimer's disease have reported increased plasma anti-Aβ antibody titres associated with decreased Aβ peptide levels in the cerebrospinal fluid following IVIg treatment. These changes at the molecular level were accompanied by improved cognitive function, and large-scale randomized trials are under way.
Subcutaneous immunoglobulin: opportunities and outlook

Published: October 2009

Summary
Immunoglobulin (Ig) administration via the subcutaneous (s.c.) route has become increasingly popular in recent years. The method does not require venous access, is associated with few systemic side effects and has been reported to improve patients' quality of life. One current limitation to its use is the large volumes which need to be administered. Due to the inability of tissue to accept such large volumes, frequent administration at multiple sites is necessary. Most studies conducted to date have investigated the use of subcutaneous immunoglobulin (SCIg) in patients treated previously with the intravenous (i.v.) formulation. New data now support the use of s.c. administration in previously untreated patients with primary immunodeficiencies. SCIg treatment may further be beneficial in the treatment of autoimmune neurological conditions, such as multi-focal motor neuropathy; however, controlled trials directly comparing the s.c. and i.v. routes are still to be performed for this indication. New developments may further improve and facilitate the s.c. administration route. For example, hyaluronidase-facilitated administration increases the bioavailability of SCIg, and may allow for the administration of larger volumes at a single site. Alternatively, more concentrated formulations may reduce the volume required for administration, and a rapid-push technique may allow for shorter administration times. As these developments translate into clinical practice, more physicians and patients may choose the s.c. administration route in the future.
Functional analysis of dendritic cell–T cell interaction in sarcoidosis
Authors: Kulakova N , Urban B , McMichael A J , Ho L-P 
Published: October 2009

SummaryThe primary cause of the intense immune response in sarcoidosis is unclear. Potentially, a functional abnormality in dendritic cells (DCs) could cause a reduction in clearance of antigen and downstream persistence in immune activity. In this study, we investigate the interaction between monocyte-derived dendritic cells and T cells in patients with sarcoidosis compared to normal controls (n = 8 each) by examining the kinetics of autologous and allogeneic mixed leucocyte reactions over 9–10 days. We found markedly depressed proliferation kinetics in autologous DC-peripheral blood mononuclear cell (PBMC) co-cultures from sarcoid patients compared to normal subjects. In allogeneic experiments PBMCs from patients showed a reduced response to allogeneic DCs from a single donor, but no difference was observed in the ability of patients and control DCs to stimulate proliferation of allogeneic PBMC from a single donor. We conclude that there is a markedly impaired autologous mixed leucocyte reaction (MLR) in sarcoidosis patients. In allogeneic MLR, monocyte-derived DCs in sarcoidosis were able to stimulate T cells normally, but PBMCs responses were reduced. This contradicts recent published studies on ex vivo isolated myeloid DCs from sarcoidosis patients although, potentially, an in vivo conditioning factor, which reduces DC function in sarcoidosis, could be a unifying explanation for the contrasting findings.
Differential selection on sprint speed and ad libitum feeding behaviour in active vs. sit‐and‐wait foraging spiders
Authors: Pruitt Jonathan N. 
Published: October 2009

Summary 1. Many animals are adapted for a ‘feast or famine’ existence, and will opportunistically engage in gluttonous foraging bouts. However, how gluttonous feeding influences individual performance (e.g. running speed) and the fitness consequence of modified performance are not frequently considered. 2. Using laboratory track trials I establish baseline locomotor performances (burst speed) for four spider species: two active foragers (Hogna helluo and Schizocosa ocreata (family: Lycosidae)), and two sit‐and‐wait foragers (Agelenopsis emertoni and Barronopsis texana (family: Agelenidae)). I then fed each species ad libitum, assessed what influence this meal had on individuals’ burst speed relative to baseline performance, and performed a field census to assess selection on running speed for all four species. 3. Sit‐and‐wait foragers fed significantly more than active foragers and slowed significantly after feeding; however, neither active forager was slowed by their meal. 4. My field census detected no selection on speed for sit‐and‐wait foragers, and positive directional selection on speed for both active foragers. 5. The negative association between the amount of food consumed and selection on burst speed suggests that selection pressures to maintain locomotor performance may set an upper limit to how much an animal can, or will, eat during a foraging bout.
Tunic morphology and viral surveillance in diseased Korean ascidians: soft tunic syndrome in the edible ascidian, Halocynthia roretzi (Drasche), in aquaculture

Published: October 2009

Abstract‘Soft tunic syndrome’ causes mass mortality in the edible ascidian Halocynthia roretzi in Korean and Japanese aquaculture. In histopathological comparison, there were no specific differences between diseased specimens from Korea and Japan, indicating that soft tunic syndrome occurring in Korea and Japan is the same disease. No bacterial or protozoan cells were microscopically detected in either healthy or diseased tunics suggesting they are not the direct causes of soft tunic syndrome. Attempts were made to isolate virus from affected ascidians taking into account temperature conditions in which soft tunic syndrome is most prevalent in the field. However, no viruses were isolated from diseased or non‐diseased specimens using chinook salmon embryo (CHSE‐214), flounder fin (FFN) or epithelioma papillosum cyprini (EPC) cell lines.
Koi herpesvirus: distribution and prospects for control in England and Wales

Published: October 2009

AbstractKoi herpesvirus (KHV) causes a highly virulent disease affecting carp, Cyprinus carpio L., and poses a serious socio‐economic threat to the UK carp industry. This study aimed to determine the geographic distribution and prevalence of KHV exposed fish in England and Wales through ELISA antibody testing. Only three of the 82 farms sampled produced positive results, suggesting fish farms provide a relatively safe source of fish. Of the 71 ‘high‐risk’ fisheries tested, 26 were positive. All eight geographic areas within England and Wales studied had at least one KHV positive site. Twelve consignments of imported koi carp from seven S.E. Asian countries were tested for KHV antibody. Six consignments from six different countries were positive. Although a high proportion of consignments were positive, the results indicate that lower risk stocks of fish exist that could be sourced by the ornamental carp sector. The study provides evidence that KHV is widespread and prevalent in ‘high‐risk’ fisheries. There are, however, prospects for controlling KHV as English and Welsh farms appear to be relatively free of the virus, and in most cases fish are not moved from fisheries to other waters.
Using personal goal setting to promote the social inclusion of people with intellectual disability living in supported accommodation
Authors: McConkey R. , Collins S. 
Published: October 2009

AbstractBackground  The social exclusion of persons with intellectual disability is more marked in congregated than in individualised supported accommodation. Goal setting was used as a means of increasing individuals' choices and engaging support staff in personalised planning.Method  People living in four different housing and support options were invited to identify up to three ‘social inclusion’ goals they wanted to achieve in the coming months. Nine months later, a review was undertaken to see if their goals had been attained and also to identify what had helped or hindered individuals in doing this. The goal selection was then repeated and reviewed again after a further 9 months.Results  The most commonly chosen goals were around social activities with other people and over half the participants were reported to have attained at least one of their goals within 9 months, particularly those in supported living arrangements that had greater hours of individual staff support. In the second 9‐month period, fewer people chose goals, although the same proportion as before were successful. The main reason given for goal attainment was the information and support provided by staff.Conclusions  Goal setting seems a suitable way of promoting social inclusion as it can be tailored to the needs and aspirations of individuals, although extra efforts may be needed to implement and sustain it with staff across all accommodation options.
