SUMMARYLow-temperature stress is an important limiting factor to tobacco growth in early spring of south China. In this study, a low-temperature-resistant agent (LTRA) was employed to examine its ameliorating effect on the inhibition of tobacco growth triggered by low-temperature stress. Results indicated that low-temperature stress of 12 °C for 6 days reduced root number and biomass of tobacco seedling by 27.4% and 24.1%, while treatment with LTRA could recover the inhibitory effect of low-temperature stress on tobacco growth significantly. The content of ascorbic acid and the activities of superoxide dismutase and catalase at low-temperature stress were 65.2%, 53.5% and 32.1% of those at normal temperature condition (26 °C), while the corresponding values with LTRA treatment were 89.2%, 88.9% and 74.2%, suggesting that LTRA treatment could enhance the activity of antioxidant enzyme and the synthesis of antioxidant compounds. Low-temperature stress increased the membrane permeability by 84.8%, while LTRA treatment recovered it by 77.4%. Furthermore, LTRA treatment contributed to increase chlorophyll synthesis and maintain the integrity of tobacco leaf structure. Effective component analysis indicated that the complex of ammonium calcium nitrate and glycine betaine was the main effective component of LTRA in maintaining membrane integrity. Its effective concentration was 1.0 g L−1. The above results suggested that LTRA could enhance the synthesis of chlorophyll, activate the activity of antioxidant enzyme, maintain the integrity of cell membrane, and thus elevate the tolerance of tobacco seedlings to low-temperature stress.

Abstract:Understanding the habitat preferences of native and non-native species may offer valuable insights into the mechanisms favouring invasion of disturbed habitats. This study investigated the determinants of trap-site detection probability of three native (Maxomys surifer, Maxomys whiteheadiandLeopoldamys sabanus) and one invasive (Rattus rattus) species of terrestrial murid (Muridae) in logged and unlogged forests of northern Borneo. We established four and two trapping grids in repeatedly logged and unlogged forest, respectively, for a total of 500 sampled trap sites. From these, we obtained 504 detections of the four species over 3420 trap nights. For each species, probability of detection was modelled as a function of both the structural components and disturbance level of the forest patch measured around each trap site. Each of the four species showed contrasting microhabitat preferences:M. suriferfavoured increased canopy closure and intermediate ground and understorey vegetation cover;M. whiteheadipreferred increased ground vegetation cover and canopy height;L. sabanusfavoured sites with larger amounts of coarse woody debris and less leaf litter; andR. rattuswas associated with increased ground vegetation cover. Within logged forest, detection probabilities of the three native species did not vary significantly with level of patch disturbance, whereas that of the invasiveR. rattusincreased markedly in more degraded sites. This latter finding will have increasingly important implications when considering the rapid degradation of forests in the region, and the resulting expansion of suitable habitat for this competitive species.
Sustainable reduction of nasal colonization and hand contamination withStaphylococcus aureusin food handlers, 2002–2011

Published: October 2014

SUMMARYA longitudinal study of nasal colonization and hand contamination of food handlers withStaphylococcus aureuscommenced in 2002 prior to the outbreak of severe acute respiratory syndrome. In the follow-up in 2003 when hygiene measures were strictly implemented, significant reductions in carriage were observed. To investigate if this change was sustained, nasal and hand carriage rates were compared between the earlier studies and a further sampling in 2011. The initial nasal carriage rate was 35% and hand contamination 41·2%, decreasing to 23·5% and 11·6%, respectively in 2003 (P< 0·001). In 2011, nasal carriage was similar to 2003 (22·9%), while hand contamination dropped further to 3·7% (P< 0·001).Spa-typing revealed 39 types in 2002 and 42 in 2011. This study reveals that the marked reduction in colonization had been sustained. This may be attributed to reduced opportunities for spread due to enhanced hygiene and reinforces its importance for control of disease.

Published: October 2014

Background.The Camberwell Assessment of Need – Forensic Version (CANFOR) is a standardised assessment tool specifically designed to assess needs for care in forensic psychiatric populations. The original English version of the instrument has shown good psychometric properties. The aim of this study was to validate the Italian version of the CANFOR-staff tool.Method.After translation and back-translation, the Italian CANFOR tool was administered to a sample of 50 forensic psychiatric patients. Convergent validity was tested using the Brief Psychiatric Rating Scale (BPRS) and the Global Assessment of Functioning (GAF) by applying Kendall's tau-b. Inter-rater and test–retest reliabilities were measured by ICCs for need dimensions (total and unmet) and Cohen's kappa coefficients for individual need items.Results.Regarding convergent validity, a higher number of needs (total and unmet) were associated with more severe psychiatric symptoms (BPRS). Higher numbers of unmet needs were also associated with lower levels of global functioning (GAF). ICCs for total and unmet needs scores indicated a good level of agreement for inter-rater reliability and a very good level for test–retest, respectively. Regarding the specific items, inter-rater Cohen's kappa was high (moderate to very good agreement) for 18 items in relation to the presence of a need and for 15 items in the rating of an unmet need, whereas Cohen's kappa for test–retest reliability was very high for all the items in the presence of a need and high for 18 of the unmet need domains.Conclusions.The Italian version of CANFOR has adequate psychometric properties. It can be considered a promising instrument for the assessment of needs of forensic psychiatric patients.

Published: October 2014

AbstractThe aim of this study is to determine the prevalence rate of ODD in school age children, and analyze the variability of the prevalence rates per informant, according to the sources of information, sex, age, and level of agreement between teachers and parents. This is an epidemiological study conducted using a community sample extracted by means of multi-stage stratified sampling. The sample consisted of 1,295 children of both sexes from 6 to 8 years old. For diagnostic evaluation, the Oppositional Defiant Disorder Rating Scale (ODDRS-IV) was used. The estimated global prevalence of ODD, detected by all sources is 16.1%. But if we consider the percentage of subjects detected by only one informant, the prevalence rate is 9.5%. The prevalence according to teachers is 5.1% (95% CI = 3.88–6.31), according to fathers is 9% (95% CI = 7.38–10.54), and according to mothers is 9.7% (95% CI = 8.02–11.29). Teachers report more boys with ODD than girls. Results support the idea of high variability in ODD prevalence rates. Our findings suggest that parents are more prone to detect the disorder than teachers, and that boys present ODD more frequently than girls, only when they are evaluated by their teachers.

The authors developed a high‐efficiency gallium‐nitride (GaN) Class‐E converter for a 6.78 MHz magnetic resonant wireless power transfer system. A negative‐bias gate driver circuit made it possible to use a depletion mode GaN high‐electron‐mobility transistor (HEMT), and simplified the converter circuit. As the depletion mode GaN HEMT with very small gate–source capacitance provided almost ideal zero‐voltage switching, the authors attained a drain efficiency of 98.8% and a total efficiency of 97.7%, including power consumption of a gate driver circuit, at a power output of 33 W. In addition, the authors demonstrated a 6.78 MHz magnetic resonant wireless power transfer system that consisted of the GaN Class‐E converter, a pair of magnetic resonant coils 150 mm in diameter with an air‐gap distance of 40 mm, and a full‐bridge rectifier using Si Schottky barrier diodes. The system achieved a dc–dc efficiency of 82.8% at a power output of 25 W. The efficiencies of coil coupling and the rectifier were estimated to be ∼ 94 and 90%, respectively.
Gabriel Fauré's Middle-Period Songs, Editorial Quandaries and the Chimera of the ‘Original Key’
Authors: Howat Roy , Kilpatrick Emily 
Published: October 2014

ABSTRACTThe years 1886–91 saw Gabriel Fauré developing a new boldness and intensity in his composition of mélodies, prompted in part by the discovery of new poets (notably including Villiers de l'Isle Adam and Verlaine), and arguably also by his acquaintance with the excellent tenor Maurice Bagès. In particular, the songs of this period (spanning the opus groups 43–58) reveal an intriguingly exploratory approach to transposition, tessitura, timbre and texture. These songs are also remarkable for the seriousness and complexity of their pre- and post-publication revisions. The present study considers these revisions in relation to what is known of Fauré's habits and performing preferences, and in the light of his relationship with Bagès. It explores the practical and conceptual challenges the songs pose for the critical editor: how do we balance the logical principle of Fassung letzter Hand against the occasional musical compromise that appears to have ensued?
Don Juan in Nadsat: Kubrick's Music for A Clockwork Orange
Authors: Code David J. 
Published: October 2014

ABSTRACTThe critical reception of Kubrick's A Clockwork Orange (1971) often circles around two related questions: its relationship to Anthony Burgess's 1962 novel and the implications of its classical ‘compilation’ soundtrack. Revisiting both, this article challenges the pervasive emphasis in existing musicological literature on the film's use of Beethoven's Ninth Symphony by offering a formal analysis of its excerpts by (among others) Rossini, Elgar and Purcell. A fresh look at Purcell's Funeral Music for Queen Mary (1695) serves to open a dramatic lineage leading back to the seventeenth-century ‘Don Juan’ archetype, which brings in tow the vast musicological literature on Don Giovanni along with philosophical accounts from Kierkegaard through Bernard Williams. The film's notorious references to Gene Kelly's dance routine in Singin’ in the Rain (1952) add to its confrontation with individual and collective ideals of ‘liberty’ a cinematic reflexivity that can serve (with some help from Marshall McLuhan's influential 1964 study Understanding Media) to shed new light on Luis Buñuel's assertion that this is ‘the only movie about what the modern world really means’.
What Works? An Empirical Perspective on how to Retain Youth in Longitudinal Human Immunodeficiency Virus (HIV) and Substance Risk Reduction Studies
Authors: Montanaro Erika , Feldstein Ewing Sarah W. , Bryan Angela D. 
Published: October 2014

Background Low retention rates are a problem for longitudinal studies involving adolescents, and this is particularly true for justice-involved youth. Methods This study evaluates (1) strategies used to retain high-risk adolescents participating in a longitudinal research project; (2) the extent to which retention efforts were different in a justice-involved versus a non–justice-involved (school-based) sample; and (3) differential characteristics of justice-involved versus school-based adolescents that might explain differences in retention difficulty. Results Compared with the school-based youth, justice-involved youth required significantly more phone calls to be successfully reached. Additionally, baseline substance use (alcohol and marijuana use frequency) was higher in the justice-involved sample and significantly related to retention difficulty. Conclusions High retention rates for justice-involved and substance-using youth are possible with focused efforts on frequent communication and effortful contact.

Published: October 2014

Background Smartphone applications can potentially provide recovery monitoring and support in real-time, real-life contexts. Study aims included determining feasibility of (a) adolescents completing ecological momentary assessments (EMAs) and utilizing phone-based ecological momentary interventions (EMIs); and (b) using EMA and EMI data to predict substance use in the subsequent week. Methods Twenty-nine adolescents were recruited at discharge from residential treatment, regardless of their discharge status or length of stay. During the 6-week pilot, youth were prompted to complete an EMA at 6 random times per day and were provided access to a suite of recovery support EMI. Youth completed 87% of the 5580 EMAs. Based on use in the next 7 days, EMA observations were classified into 3 risk groups: “Current Use” in the past 30 minutes (3% of observations), “Unrecognized Risk” (42%), or “Recognized Risk” (55%). All youth had observations in 2 or more risk groups and 38% in all 3. Youth accessed an EMI on average 162 times each week. Results Participants were 31% female, 48% African American, 21% Caucasian, 7% Hispanic, and 24% Mixed/Other; average age was 16.6 years. During the 90 days prior to entering treatment, youth reported using alcohol (38%), marijuana (41%), and other drugs (7%). When compared with the “Recognized Risk” group's use in the following week (31%), both the “Unrecognized Risk” (50%, odds ratio [OR] = 2.08) and “Current Use” (96%, OR = 50.30) groups reported significantly higher rates of use in the next week. When an EMI was accessed 2 or more times within the hour following an EMA, the rate of using during the next week was significantly lower than when EMIs were not accessed (32% vs. 43%, OR = 0.62). Conclusions Results demonstrate the feasibility of using smartphones for recovery monitoring and support with adolescents, with potential to reduce use.
The relationship between critical speed and the respiratory compensation point: Coincidence or equivalence
Authors: Broxterman R. M. , Ade C. J. , Craig J. C. , Wilcox S. L. , Schlup S. J. , Barstow T. J. 
Published: October 2014

AbstractIt has previously been suggested that the respiratory compensation point (RCP) and critical speed (CS) parameters are equivalent and, therefore, like CS, RCP demarcates the boundary between the heavy‐ and severe‐intensity domains. However, these findings are equivocal and therefore must be interpreted cautiously. Thus, we examined the relationship between CS and RCP across a wide range of subject fitness levels, in an attempt to determine if CS and RCP are equivalent. Forty men and 30 women (age: 23.2 ± 2.5 year, height: 174 ± 10 cm, body mass: 74.1 ± 15.7 kg) completed an incremental and four constant‐speed protocols on a treadmill. RCP was determined as the point at which the minute ventilation increased disproportionately to CO2 production and the end‐tidal CO2 partial pressure began to decrease. CS was determined from the constant‐speed protocols using the linearized 1·time−1 model. CS and RCP, expressed as speed or metabolic rate, were not significantly different (11.7 ± 2.3 km·h−1 vs. 11.5 ± 2.3 km·h−1, p = 0.208; 2.88 ± 0.80 l·min−1 vs. 2.83 ± 0.72 l·min−1, p = 0.293) and were significantly correlated (r2 = 0.52, p < 0.0001; r2 = 0.74, p < 0.0001, respectively). However, there was a high degree of variability between the parameters. The findings of the current study indicate that, while on average CS and RCP were not different, the high degree of variability between these parameters does not permit accurate estimation of one from the other variable and suggests that these parameters may not be physiologically equivalent.
Standing out from the crowd: niche product choice as a form of conspicuous consumption
Authors: Schaefers Tobias 
Published: October 2014

Purpose
– This paper aims to define the niche market concept and to investigate the extent to which purchasing niche products represents a form of conspicuous consumption. Consumers increasingly seek products that differ from the mainstream, and companies regard niche markets as a promising opportunity beyond saturated mass markets.

Design/methodology/approach
– Based on survey data that combines self-report scales and actual purchase decisions, the effects of different dimensions of conspicuous consumption on niche product choice are investigated using binary logistic regression.

Findings
– Choosing niche products over mass market products is mainly influenced by differentiation tendencies. Moreover, consumers use niche products to strengthen their role as opinion leaders. Choice of mass market products, on the other hand, is influenced by assimilation tendencies. In contrast to common assumptions, status-seeking consumers are more likely to choose a mass market alternative over niche products.

Research limitations/implications
– Based on the conceptualization of niche markets, this study reveals that niche products are a means for consumers to distinguish themselves. Limitations include the focus on a single product domain and country. Future research should replicate the study for other types of niche products and in other cultural settings.

Practical implications
– Niche firms should explicitly consider the social effects of conspicuous consumption as a key driver of demand. Specifically, the unique nature of a niche product should be highlighted and recognizable to increase the acceptance among potential customers. Moreover, instead of focussing the status of niche products, marketing activities should address opinion leaders’ desire to maintain their standing among the social group by providing in-depth information and enhanced customer experience.

Originality/value
– This paper addresses the call for a conceptual definition of niche markets. Moreover, while previous work focussed on the company perspective, this study allows for an improved understanding of consumer behaviour with regard to niche markets.
The mediating impact of stickiness and loyalty on word-of-mouth promotion of retail websites
Authors: Kumar Roy Sanjit , M. Lassar Walfried , T. Butaney Gul 
Published: October 2014

Purpose– The purpose of the study is to develop and empirically test a model which examines the relationship between e-servicescape dimensions, website quality dimensions, website stickiness, website loyalty and word-of-mouth (WOM). The role of WOM in influencing consumer behaviour is documented in literature. However, despite its growing importance, research on the antecedents of WOM in the e-retail context is sparse.Design/methodology/approach– Data were collected by circulating the questionnaire using an online survey from the graduate and undergraduate students enrolled in a large university in the northeastern USA. Out of 660 questionnaires distributed, 509 were usable. Data were analysed using confirmatory factor analysis and structural equation modelling.Findings– Results show that website stickiness and website loyalty are two different constructs which form the immediate antecedents of WOM. Results also show the indirect effects of e-servicescape and website quality dimensions on WOM.Practical implications– The findings of the study provides a better understanding of the factors likely to influence the WOM behaviour of e-retail store customers. Findings also provide valuable insights into the factors which managers need to focus on to make their e-retail website increasingly stickier.Originality/value– The contribution of the paper lies in eliciting the differences between stickiness to and loyalty to retail websites and extending the research on e-servicescapes.
Rethinking brand architecture: a study on industry, company- and product-level drivers of branding strategy
Authors: Strebinger Andreas 
Published: October 2014

Purpose
– This study aims to compare academic prescriptive models on how to choose a branding strategy on the continuum from a “branded house” to a “house of brands” with real-life branding strategies of leading companies.

Design/methodology/approach
– Data from an executive survey, observations and desk research on 75 leading companies in Austria are analysed with multilevel weighted least squares (WLS) regression.

Findings
– Branding strategies for products are determined by industry (23 per cent of variance), the overall strategy of the company (28 per cent), the remaining variance being product-level decisions deviating from both. Service and consumer durables companies lean more towards corporate branding than consumer nondurables. On the company level, synergies in advertising, e-commerce and e-CRM (customer-relationship management) increase the usage of shared brands. A higher company age leads to brand proliferation. On the product level, quality differences between products, the emphasis on and differences in experiential product positioning and, marginally, the symbolic differences between products favour individual brands.

Research limitations/implications
– Future research should investigate additional markets, additional drivers, small and medium-sized entreprises (SMEs) and employ additional measures.

Practical implications
– The study informs brand-architecture audits with benchmarks from leading companies, calls for a view of brand architecture more flexible than ideal-type categories proposed in literature and cautions against management inertia, industry standards and trends in designing branding strategies.

Originality/value
– This study is the first quantitative cross-industry multi-level study on real-life branding strategies. It also applies a new conceptualisation and measurement of branding strategy.
