Adjuvants to improve aerial control of the citrus mealybug Planococcus citri (Hemiptera: Pseudococcidae) using entomopathogenic nematodes
Authors: van Niekerk S. , Malan A.P. 
Published: November 2013

AbstractThe citrus mealybug, Planococcus citri, is a highly destructive pest of citrus, occurring only in the aerial parts of plants. Humidity will be one of the key factors to consider when using entomopathogenic nematodes (EPN) as biological control agents. Different adjuvants can be added to suspensions of EPNs, to improve control as a foliar application. An aqueous suspension containing Heterorhabditis zealandica and 0.3% Zeba® significantly increased P.citri mortality by 22% at 80% relative humidity (RH) with a temperature cycle starting at 22°C for 14 h and 11°C for 11 h. The same polymer formulation was tested for Steinernema yirgalemense and mortality of P. citri increased by 21% at 60% RH and by 27% at 80% RH. The addition of Nu-Film-P® and Zeba® to H. zealandica suspensions did not significantly retard application run-off on citrus leaves. The combination of Nu-Film-P® and Zeba®, however, was able to significantly retard sedimentation, increasing the average number of nematodes deposited on 2-cm2 leaf discs by 10 nematodes. In an aqueous suspension, nematodes settle rapidly to the bottom, resulting in an uneven distribution of nematodes. Xanthan gum, at a concentration of 0.2%, was highly effective at retarding sedimentation, with 72% of the initial nematode number still in suspension after 1 h. Zeba®, at a concentration of 0.3%, despite not being as effective as Xanthan gum, nevertheless still retarded sedimentation significantly. This is the first report of the potential of Nu-Film-P® and Zeba® to improve EPN performance against P. citri when used above ground in citrus orchards.

AbstractBackground:Serum paraoxonase 1 is involved in mechanisms that protect cells from oxidative stress damage. This study aimed to investigate the correlation between serum paraoxonase 1 activity and polymorphisms in patients with oral squamous cell carcinoma.Methods and materials:Fifty-seven patients with oral squamous cell carcinoma and 59 matched healthy controls participated in the study. Serum paraoxonase 1 activity and polymorphisms in blood samples were compared with results for polymerase chain reaction and restriction fragment length polymorphism tests.Results:Mean serum paraoxonase 1 activity levels were lower in patients than controls (mean ± standard deviation, 21.9 ± 5 units/l and 120.4 ± 2 units/l, respectively) (p = 0.001). The serum paraoxonase 1 192 glutamine polymorphism was more common in patients than controls.Conclusion:Patients with oral squamous cell carcinoma had significantly lower serum paraoxonase 1 activity levels and a greater prevalence of the serum paraoxonase 1 192 glutamine allele, compared with controls. Serum paraoxonase 1 may play a role in the aetiology of oral squamous cell carcinoma.

Published: November 2013

AbstractMany endemic species, particularly those on remote islands, have been driven to extinction or near extinction by anthropogenic influences. The short-tailed albatross Phoebastria albatrus once numbered in the millions but was thought to be extinct by the mid 20th century. Albatrosses, of the family Diomedeidae, are among the most threatened birds globally as a result of commercial exploitation, introduced predators, and mortality in commercial fisheries. We applied an experimental approach over 5 years to evaluate the translocation and hand-rearing of albatross chicks by comparing growth, physiological health indices, post-fledging survival, and migration patterns with a control group of naturally reared chicks in the source population. Hand-reared chicks had comparable or superior health and similar rates of immediate post-fledging mortality (15%), with mortality strongly female-biased in both groups. Hand-reared birds had longer post-fledging drift periods before attaining sustained flight (also female-biased) but comparable, albeit somewhat wider ranging, migration patterns to naturally reared chicks during their first 6 months at sea. Recruitment to the translocation site of a breeding pair that included a hand-reared bird occurred within 5 years of the first translocation. Success will ultimately depend on continued recruitment and breeding over the coming decades, given delayed breeding in these long-lived species. The results to date, however, have exceeded initial expectations and can inform potential reintroductions of other long-lived, migratory avian species with strong natal philopatry, and reintroductions of native species to former breeding islands.
‘We ate lots of fish back then’: the forgotten importance of fishing in Gwich'in country
Authors: Wishart Robert P. 
Published: November 2013

ABSTRACTThis article attempts to reconcile the fact that fishing has been and continues to be a large part of the Gwich'in local economy with the fact that fishing has been neglected in both popular and scientific accounts of Gwich'in practice. The article puts forth an explanation for why fishing has been neglected while at the same time documenting the corpus of fishing activities included in the yearly round. It also situates fishing as an important, but largely underestimated, part of the Canadian fur trade and explains how fish came to be used by traders and Gwich'in in a system of advances that benefited both parties. As a so-called secondary activity, fishing is entangled in Gwich'in history and their current way of life, and this article challenges the idea that it can be easily separated from other land based activities.
Globalization, Social Justice Issues, Political and Economic Nationalism in Taiwan: An Explanation of the Limited Resurgence of the DPP during 2008–2012
Authors: Qi Dongtao 
Published: November 2013

AbstractTaking a broader perspective to explore the relations between Taiwan's globalization, social justice issues and the DPP's political and economic nationalism, this study aims to understand the DPP's resurgence in local elections since 2008, and its defeat in the 2012 presidential election. Increasing capital flight from Taiwan to mainland China has contributed to Taiwan's rising unemployment and income inequality. Less privileged Taiwanese, having stronger nationalist sentiments and concerns about the Taiwanese government's open-door China policy, switched their support from the KMT to the DPP during the DPP administration of 2000–2008. Since 2008, the DPP's better balance between its political and economic nationalism has been instrumental in securing popular support, especially at the local level. Nevertheless, in the 2012 presidential election, the DPP failed to convince the majority of Taiwanese voters that its moderate political nationalism could maintain the significantly improved cross-Strait relations vital for Taiwan's economic revival under the current bleak world economic conditions.
Évaluation de l’aptitude d’une personne âgée atteinte de déficits cognitifs à gérer sa personne et ses biens : Identification des outils disponibles

Published: November 2013

AbstractThe accelerated aging of the Canadian population is a recognized fact and leads to an increasing number of seniors with cognitive impairments (Curateur public du Québec, 2010a). This has a definite impact on health professionals who have to assess their competency to live independently and manage their finances. This decision, which has important consequences for the person, must be based on an objective and rigorous assessment. The purpose of this paper is to analyse the available tools, both in the scientific literature and in clinical settings, to better document the various components to assess seniors’ competency to live independently and manage their finances. The goal is to help practitioners who work with older people with cognitive impairments to accurately assess their ability to manage themselves and their property. A review of the relevant literature and training available, as well as three group consultations, showed that there is no consensus about the tools used to assess the capacity to take care of oneself and one’s property. Additional studies are thus needed to fill the gap in knowledge about specific tools used to assess competency.

SUMMARYAnalysis of the Dutch national invasive pneumococcal disease (IPD) surveillance data by sex reveals an increase in the incidence of serotype-1 disease in young female adults in The Netherlands after the introduction of the 7-valent pneumococcal conjugate vaccine (PCV7) in the national immunization schedule. This has led to an overall increase in IPD in women aged 20–45 years, which was not observed in men of the same age. No other differences in serotype shifts possibly induced by the introduction of PCV7 were observed between the sexes in this age group. Serotype 1 is a naturally fluctuating serotype in Europe and it has been associated with disease in young healthy adults before. It remains uncertain whether or not there is an association between the observed increase in serotype-1 disease in young female adults and the implementation of PCV7 in The Netherlands.
The morpho-syntactic status of ne and its effect on the syntax of imperative sentences
Authors: PÉTERS HUGUES 
Published: November 2013

ABSTRACTThis article argues that there is compelling evidence that Frenchne, even in dialects that still have this particle, is no longer negative, does not determine the scope of negation with respect to other operators, does not have properties of a head (optionality), and therefore cannot be analysed as the head of NEGP in Modern Standard French. Rather,neshould be considered as an affix merged to a Tense projection (TNSP) endowed with sub-label features of polarity. This article argues that this proposal provides a unified solution for the distributional properties ofnein finite and non-finite contexts alike. It especially provides an explanation for the structure of French negative imperatives, which are characterised by the proclisis of argument clitics (ne le prends pas‘don't take it’), crucially linked to properties of Tense, as opposed to their enclisis in positive imperatives (prends-le‘take it’) and in spoken registers whereneis absent (prends-le pas‘don't take it’).
French imperatives, negativene, and non-subject clitics
Authors: ROWLETT PAUL 
Published: November 2013

ABSTRACTThis article focuses on the behaviour of negation and clitics in the context of French imperatives. Standard descriptions contrast positiveFais-le !(with enclisis) with negative(Ne) le fais pas !(with proclisis). I adopt a view of imperatives in terms of a pragmatic irrealis mood feature associated with Rizzi's (1997) exploded CP and defective/impoverished morphology which allows inflection and irrealis mood features to be checked on a single functional head. Thus, positive imperatives can check all their grammatical features before merger of any clitics, which (following Shlonsky, 2004) will therefore be enclitic. The presence of negation, when realised as a grammatical feature on an (overt or null) functional head within the clausal trunk, prevents this from happening because negation intervenes between the relevant inflection and mood features in the universal hierarchy underlying the Rizzi/Cinque exploded CP/IP. Outside cliticisation contexts, the difference has no surface impact:Viens !vs.(Ne) viens pas !In cliticisation contexts, in contrast, there is a surface difference: negative imperatives cannot check all their inflectional features at the point at which clitics are merged, and clitics will not therefore be enclitic. Regionally/stylistically marked forms likeFais-le pas !, in which proclisis and negation co-occur, must be deemed to have a radically different structure, with no negative feature projected within the inflectional domain. Such forms are argued to be a natural (and therefore expected) innovation within Jespersen's cycle of diachronic development.
Formative assessment of oncology trainees' communication with cancer patients about internet information
Authors: Bylund Carma L. , Sperka Miryam , D'Agostino Thomas A. 
Published: November 2013

AbstractObjective:Cancer patients and their caregivers often turn to the internet for information and support following a cancer diagnosis. Research shows a need for improvement in doctors' communication with patients about internet information. The purpose of this formative assessment was to evaluate oncology trainees' skills in talking about internet information with cancer patients.Methods:Thirty-nine oncology trainees were evaluated in a baseline standardized patient assessment as part of their participation in the Comskil Training Program. As part of the assessment, standardized patients were instructed to raise the topic of internet information they had read. Transcriptions of the video-recorded assessments were coded for patient statements and trainee responses.Results:Fifty-six percent of trainees used a probe to get more information before addressing the content of the internet search, while 18% addressed it immediately. Eighteen percent of trainees warned the patient about using the internet, and 8% warned about and also encouraged internet use. Thirteen percent of trainees praised the patient for seeking out information on the internet.Significance of results:This formative assessment indicated that the majority of trainees addressed the content of the internet search, while a minority addressed the internet as a tool and praised patients' efforts. Research in this area should examine the effectiveness of educational interventions for trainees to improve discussions about internet information.
Identifying socio-environmental factors that facilitate resilience among Canadian palliative family caregivers: A qualitative case study
Authors: Giesbrecht Melissa , Wolse Faye , Crooks Valorie A. , Stajduhar Kelli 
Published: November 2013

AbstractObjective:In Canada, friends and family members are becoming increasingly responsible for providing palliative care in the home. This is resulting in some caregivers experiencing high levels of stress and burden that may ultimately surpass their ability to cope. Recent palliative care research has demonstrated the potential for caregiver resilience within such contexts. This research, however, is primarily focused on exploring individual-level factors that contribute to resilience, minimizing the inherent complexity of this concept, and how it is simultaneously influenced by one's social context. Therefore, our study aims to identify socio-environmental factors that contribute to palliative family caregiver resilience in the Canadian homecare context.Methods:Drawing on ethnographic fieldnotes and semistructured interviews with family caregivers, care recipients, and homecare nurses, this secondary analysis employs an intersectionality lens and qualitative case study approach to identify socio-environmental factors that facilitate family caregivers' capacity for resilience. Following a case study methodology, two cases are purposely selected for analysis.Results:Findings demonstrate that family caregiver resilience is influenced not only by individual-level factors but also by the social environment, which sets the lived context from which caregiving roles are experienced. Thematic findings of the two case studies revealed six socio-environmental factors that play a role in shaping resilience: access to social networks, education/knowledge/awareness, employment status, housing status, geographic location, and life-course stage.Significance of Results:Findings contribute to existing research on caregiver resilience by empirically demonstrating the role of socio-environmental factors in caregiving experiences. Furthermore, utilizing an intersectional approach, these findings build on existing notions that resilience is a multidimensional and complex process influenced by numerous related variables that intersect to create either positive or negative experiences. The implications of the results for optimizing best homecare nursing practice are discussed.
Nrf2 affects the efficiency of mitochondrial fatty acid oxidation

Published: November 2013

Transcription factor Nrf2 (NF-E2 p45-related factor 2) regulates the cellular redox homoeostasis and cytoprotective responses, allowing adaptation and survival under conditions of stress. The significance of Nrf2 in intermediary metabolism is also beginning to be recognized. Thus this transcription factor negatively affects fatty acid synthesis. However, the effect of Nrf2 on fatty acid oxidation is currently unknown. In the present paper, we report that the mitochondrial oxidation of long-chain (palmitic) and short-chain (hexanoic) fatty acids is depressed in the absence of Nrf2 and accelerated when Nrf2 is constitutively active. Addition of fatty acids stimulates respiration in heart and liver mitochondria isolated from wild-type mice. This effect is significantly weaker when Nrf2 is deleted, whereas it is stronger when Nrf2 activity is constitutively high. In the absence of glucose, addition of fatty acids differentially affects the production of ATP in mouse embryonic fibroblasts from wild-type, Nrf2-knockout and Keap1 (Kelch-like ECH-associated protein 1)-knockout mice. In acute tissue slices, the rate of regeneration of FADH2 is reduced when Nrf2 is absent. This metabolic role of Nrf2 on fatty acid oxidation has implications for chronic disease conditions including cancer, metabolic syndrome and neurodegeneration.
Suppression of Cannibalism during Larviculture of Burbot through Size Grading
Authors: Barron James M , Jensen Nathan R , Anders Paul J , Egan Joshua P , Cain Kenneth D 
Published: November 2013

Abstract
The survival and percentage of North American Burbot Lota lota maculosa larvae and metamorphosing larvae presumed to have been cannibalized during a 15-d period immediately following a size-grading event were compared with those of fish in nongraded control groups. In larvae (mean TL, 11.8 mm), grading immediately produced a size distinction, as the group that passed the grader was significantly narrower and shorter than the group retained by the grader. The mean coefficient of variation of the length of larvae in the retained group was significantly lower than that of the control group, indicating that grading reduced size heterogeneity. Grading significantly increased larval survival, which averaged 74.3% and 93.3% for the passed and retained fish, respectively, compared with 59.3% in the control. Increased survival was linked to a reduction in the percentage of larvae presumed cannibalized in the graded groups. In metamorphosing larvae (mean TL, 21.0 mm), grading did not significantly change TL, width, or the coefficient of variation of length, nor did it improve survival or reduce presumed cannibalism. This study provides initial empirical evidence that size grading can be an effective way to significantly reduce cannibalism when done at the onset of cannibalism in larval-stage Burbot.
Phenotypic Comparisons among Natural-Origin, Hatchery-Origin, and Captive-Reared Female Spring Chinook Salmon from the Tucannon River, Washington
Authors: Gallinat Michael P , Chang Wan-Ying 
Published: November 2013

Abstract
We examined the effects of hatchery rearing on FL, weight, egg size, fecundity, relative fecundity, and reproductive mass of female spring Chinook Salmon Oncorhynchus tshawytscha from a population that had been in captivity for 0 (natural-origin), 18 (hatchery-origin), and 48 (captive-reared broodstock) months. Age-4 captive-reared broodstock females that were reared for their entire life in the hatchery environment had significantly lower mean FL, weight, fecundity, relative fecundity, and reproductive mass, but had significantly larger eggs than age-4 females from the other groups after correcting for body size. Hatchery-origin females had significantly lower fecundity than natural-origin fish. Our findings illustrate a phenomenon of lower overall reproductive potential for hatchery-reared fish in the form of reduced fecundity that decreases as time spent in the hatchery environment increases. We also observed that progeny of captive-reared broodstock parents, released as smolts and recaptured as returning age-4 adults, have a size and fecundity distribution that is similar to the hatchery-origin adults, suggesting that the decrease in fecundity was not a genetically linked trait.

Abstract

Background:
Facilitation of residents’ scholarly activities is indispensable to the future of medical specialties. Research education initiatives and their outcomes, however, have rarely been reported.

Methods:
Since academic year 2006, research education initiatives, including research lectures, research problem–based learning discussions, and an elective research rotation under a new research director’s supervision, have been used. The effectiveness of the initiatives was evaluated by comparing the number of residents and faculty mentors involved in residents’ research activity (Preinitiative [2003–2006] vs. Postinitiative [2007–2011]). The residents’ current postgraduation practices were also compared. To minimize potential historical confounding factors, peer-reviewed publications based on work performed during residency, which were written by residents who graduated from the program in academic year 2009 to academic year 2011, were further compared with those of rank-to-match residents, who were on the residency ranking list during the same academic years, and could have been matched with the program of the authors had the residents ranked it high enough on their list.

Results:
The Postinitiative group showed greater resident research involvement compared with the Preinitiative group (89.2% [58 in 65 residents] vs. 64.8% [35 in 54]; P = 0.0013) and greater faculty involvement (23.9% [161 in 673 faculty per year] vs. 9.2% [55 in 595]; P < 0.0001). Choice of academic practice did not increase (50.8% [Post] vs. 40.7% [Pre]; P = 0.36). Graduated residents (n = 38) published more often than the rank-to-match residents (n = 220) (55.3% [21 residents] vs. 13.2% [29]; P < 0.0001, odds ratio 8.1 with 95% CI of 3.9 to 17.2).

Conclusion:
Research education initiatives increased residents’ research involvement.
