A multi‐species dendroclimatic reconstruction of Chilko River streamflow, British Columbia, Canada
Authors: Hart Sarah J. , Smith Dan J. , Clague John J.
Published: May 2010

Dendroclimatological data were used to reconstruct the discharge history of Chilko River, which drains a glacierized watershed in the Coast Mountains of British Columbia. We correlated ring‐width records from Engelmann spruce (ES) (Picea engelmanni) and mountain hemlock (MH) (Tsuga mertensiana) trees to historical hydroclimate data. Over the period of record, spruce and hemlock radial growth correlates significantly with temperature and snow depth, respectively. We found that a multi‐species approach provided a better model fit and reconstructive power. Using these relationships, we developed generalized linear models for mean June, July, and June‐July discharge. The proxy records provide insights into streamflow variability of a typical Coast Mountains river over the past 240 years and confirm the long‐term influence of the Pacific Decadal Oscillation (PDO) on hydroclimatic regimes in the region. A relationship also exists between the reconstructed June‐July discharge record and the North Pacific (NP) Index, suggesting that winter atmospheric patterns over the North Pacific influence the hydrology of coastal British Columbia.

Identification of geographic runoff sources in a data sparse region: hydrological processes and the limitations of tracer‐based approaches
Authors: Barthold Frauke K. , Wu Jinkui , Vaché Kellie B. , Schneider Katrin , Frede Hans‐Georg , Breuer Lutz
Published: May 2010

There exists a growing need to improve our understanding of catchment processes on larger scales. This need is especially enhanced in rapidly developing countries such as China where the turnover of traditionally used land to urbanized and industrialized areas influences water resources. In this study, we chose a multi‐tracer approach in a large, ungauged basin in Inner Mongolia to elucidate the processes that generate stream flow. We applied end member mixing analysis (EMMA) to identify and quantify the major runoff generating sources in a three end member system. Stream water and a set of eight possible end members were sampled throughout three consecutive vegetation periods. Samples were analysed with an inductively coupled plasma‐mass spectrometry (ICP‐MS) and an ion chromatograph (IC) for a suite of 33 solutes including 24 cations and 7 anions. We determined that seven tracers exhibited conservative behaviour, they were Li, Rb, Sr, Na, Mg, Cl and electrical conductivity (EC). Stable water isotopes (δD and δ18O) highlight differences between the end members. Our results indicate strong interannual variability of end member composition and contribution between the 3 years. We were able to identify shallow groundwater aquifers as important runoff generating sources in some years and deeper groundwater aquifers in other years which vary in rainfall and discharge. A shallow sand dune aquifer which covers a significant part of the area plays an important role in storing and contributing water to the river. Our results also suggest that the major runoff generating source in the dryer year has not been identified yet. Our results prompt us to focus future work on understanding interannual changes in end member contribution especially in semi‐arid regions. Copyright © 2010 John Wiley & Sons, Ltd.
Effect of a human pharmaceutical carbamazepine on antioxidant responses in brain of a model teleost in vitro: an efficient approach to biomonitoring
Authors: Li Zhi‐Hua , Li Ping , Randak Tomas
Published: May 2010

Residual pharmaceuticals are generally recognized as relevant sources of aquatic environmental pollutants. In this study, the effects of carbamazepine (CBZ) on the antioxidant defense system in the brain of rainbow trout in vitro were studied. The brain homogenates were incubated with various concentrations of CBZ (1.0 µg l−1, 0.2 mg l−1 or 2.0 mg l−1) for 0, 60, 120 min. After incubation, oxidative stress indices (lipid peroxidation and carbonyl protein), antioxidant enzymes (superoxide dismutase, glutathione reductase and glutathione peroxidase) and nonenzymatic antioxidant (reduced glutathione) in each samples were measured. Based on the results, the brain homogenates performed adaptive responses to CBZ‐induced stress at environmental concentration (1.0 µg l−1). With increased CBZ concentrations (0.2 or 2.0 mg l−1), oxidative stress was apparent as reflected by the significant higher levels of oxidative indices, together with the significant inhibition of all antioxidant enzymes activities and reduced glutathione content. Compared with previous studies in vivo, the brain homogenates showed more sensitive antioxidant responses to CBZ stress. In conclusion, the brain homogenates of rainbow trout could be used as an efficient model system in aquatic risk assessment, but more detailed laboratory studies are needed before these findings could be established as special biomarkers for monitoring residual pharmaceuticals in aquatic environment.

Thymocytes are activated by toluene inhalation through the transcription factors NF‐κB, STAT5 and NF‐AT
Authors: Liu Jiqin , Yoshida Yasuhiro , Kunugita Naoki , Noguchi Junko , Sugiura Tsutomu , Ding Ning , Arashidani Keiichi , Fujimaki Hidekazu , Yamashita Uki
Published: May 2010

Toluene has been extensively examined for effects on the central nervous system. To investigate the influence of low‐level inhalation of toluene on the naive immune cells, male C3H/HeN mice were exposed to filtered air (control) and 50 ppm of toluene for 3 weeks. Low‐level exposure resulted in (1) increased proliferation of thymocytes, (2) IL‐2 production induced in thymocytes and (3) activation of the transcription factors NF‐κB, STAT5 and NF‐AT in thymocytes. These results suggest that thymocytes are sensitive cells and T cell activators are candidates for biomarkers for low‐level exposure to toluene on naive immune cells.

Advances in long‐term soil‐pollution monitoring of Switzerland
Authors: Desaules André , Ammann Stefan , Schwab Peter
Published: May 2010

The Swiss soil‐monitoring network (NABO) was launched in 1984 and comprises currently 105 observation sites covering all characteristic land‐use types across Switzerland. So far, the sampling periodicity was 5 y, and the fifth sampling campaign will be accomplished by end of 2009. The concentrations of Cd, Zn, Pb, Cu, Hg, Ni, Cr, Co, and F were measured. The major results and conclusions are: (1) Even topsoils in remote areas are to some extent polluted, mainly by Pb, Cu, and Cd. However, elevated concentrations can also be of natural origin, e.g., for F, Ni, Cr, and Cd. (2) Land use alone is often a rather unreliable indicator to discriminate soil pollution. (3) After the 2nd campaign positive, negative, or no temporal concentration changes were measured. From the 3rd campaign onwards, nonmonotonous (zigzag) evolutions were frequently observed. Therefore, no certified trends can be stated after three measurement campaigns during a period of 10 y. (4) Soil monitoring is an environmental time‐series problem. The only way to detect reliable signals and trends earlier is to improve the overall measurement quality (precision and bias) and to shorten the measurement periodicity. (5) The causes of temporal soil concentration changes are complex and result from natural processes, anthropogenic processes, and methodological artifacts. Hence, not all soil concentration changes are due to anthropogenic inputs. Based on the state‐of‐art of our experience, some basic methodological requirements and recommendations can be supported for a “good soil‐monitoring practice”: (1) Assurance of long‐term continuity and consistency under changing boundary conditions as site conditions, methodologies, etc. (2) Implementation of a scientifically and politically appropriate spatial and temporal measurement resolution. (3) Long‐term assessment of reliability (quality assurance) by adequate quantification of precision, bias, and confidence intervals along the whole measurement chain. (4) Documentation of all potentially relevant boundary conditions by suitable metadata. Only soil‐monitoring results meeting these requirements are fit to support political decisions.
A cell‐based smoothed finite element method for kinematic limit analysis
Authors: Le Canh V. , Nguyen‐Xuan H. , Askes H. , Bordas Stéphane P. A. , Rabczuk T. , Nguyen‐Vinh H.
Published: May 2010

This paper presents a new numerical procedure for kinematic limit analysis problems, which incorporates the cell‐based smoothed finite element method with second‐order cone programming. The application of a strain smoothing technique to the standard displacement finite element both rules out volumetric locking and also results in an efficient method that can provide accurate solutions with minimal computational effort. The non‐smooth optimization problem is formulated as a problem of minimizing a sum of Euclidean norms, ensuring that the resulting optimization problem can be solved by an efficient second‐order cone programming algorithm. Plane stress and plane strain problems governed by the von Mises criterion are considered, but extensions to problems with other yield criteria having a similar conic quadratic form or 3D problems can be envisaged.

Complex dispersion relation calculations with the symmetric interior penalty method
Authors: Engström C. , Wang M.
Published: May 2010

A high‐order discontinuous Galerkin method for calculations of complex dispersion relations of two‐dimensional photonic crystals is presented. The medium is characterized by a complex‐valued permittivity and we relate for this absorptive system the spectral parameter to the time frequency. We transform the non‐linear eigenvalue problem for a Lorentz material in air into a non‐Hermitian linear eigenvalue problem and uses a Krylov space method to compute approximate eigenvalues. Moreover, we study the impact of the penalty term numerically and illustrate the high convergence rate of the method. Copyright © 2010 John Wiley & Sons, Ltd.
Professional and organizational commitment in paediatric occupational therapists: the influence of practice setting
Authors: Seruya Francine M , Hinojosa Jim
Published: May 2010

The professional and organizational commitment of paediatric occupational therapists working in two distinct practice settings, schools and medically based settings, was investigated. A web‐based survey program was used to administer a questionnaire to occupational therapists employed in New York, New Jersey and Connecticut. The study employed social identity theory as a guiding perspective in understanding therapists' professional and organizational commitment. One hundred and fifty‐seven paediatric therapists responded to the Professional Commitment Questionnaire and the Organizational Commitment Questionnaire to gauge their commitment to both the profession and their employing organizations. Results indicated that paediatric therapists, regardless of employment setting, have high professional commitment. Paediatric occupational therapists employed in medically based settings indicated statistically significant higher organizational commitment than their school‐based counterparts. For therapists that work in school settings, the presence of a professional cohort did not influence professional commitment scores. As the study employed a web‐based survey methodology, only individuals who were members of associations and had access to a computer and the Internet were able to participate. Further study might include widening the participant pool as well as adding additional instruments to explore both professional and organizational commitment on a more national scale.

Objectives: The impact of social support on successful smoking cessation has been well documented. However, little is known about whether personal experience with cancer may motivate cancer survivors to support smoking cessation among their family members and friends. As a first step in this line of research, we sought to explore interest in playing a supportive role for smoking cessation as well as correlates of such interest among cancer survivors.

Methods: Cancer survivors undergoing radiation therapy (N=211) completed a 77‐item pencil–paper questionnaire. A section of the survey assessed interest in helping a smoker quit and characteristics of the smoking social network member. Respondents provided information on their smoking status, medical status, and psychosocial and behavioral factors related to cigarette smoking.

Results: Over half of the respondents 114 (54%) reported having someone close to them (family member or friend) smoking cigarettes who they thought should quit. Of these respondents (44 females, 70 males) 78% (89/114) reported they were definitely or probably interested in helping a smoker quit. Nearly all respondents wanted to help a family member (typically an adult child).

Conclusions: Results suggest the potential feasibility of engaging cancer survivors to help family members quit smoking. Research is needed to determine the optimal methods and timing for engaging the cancer patient to maximize positive effects and minimize potential harms. Copyright © 2010 John Wiley & Sons, Ltd.
Perceptions of masculinity and self‐image in adolescent and young adult testicular cancer survivors: implications for romantic and sexual relationships
Authors: Carpentier Melissa Y. , Fortenberry J. Dennis , Ott Mary A. , Brames Mary J. , Einhorn Lawrence H.
Published: May 2010

Objective: To examine adolescent and young adult (AYA) testicular cancer survivors' subjective understanding of the impact of cancer in adolescence and young adulthood, with a particular emphasis on romantic and sexual relationships.

Methods: Twenty‐one AYA testicular cancer survivors, aged 18 to 34 years, were recruited from outpatient testicular cancer follow‐up clinics and completed a semi‐structured qualitative interview that assessed the impact of testicular cancer on their romantic and sexual relationships.

Results: Four themes were identified that reflected survivors' understanding of the impact of cancer in adolescence and young adulthood: (1) embarrassment leads to delays in care‐seeking, (2) testicular cancer makes you feel different from others, (3) being different from others makes you damaged goods, and (4) cancer disclosure is difficult.

Conclusions: As these themes represent important components of being in a romantic/sexual relationship, either currently or in the future, AYA testicular cancer survivors would benefit from the development of tailored interventions focused on improving these relevant domains.

Published: May 2010

We succeeded in fabricating InGaN‐based laser diodes (LDs) with a wavelength of 518 and 488 nm under continuous wave (cw) operation. The both LDs structures were grown on conventional c‐plane GaN substrates by metal organic chemical vapor deposition (MOCVD). The threshold current and threshold voltage were 45 mA and 5.5 V at 518 nm, 30 mA and 4.5 V at 488 nm, respectively. The lifetime test of these LDs was carried out under high driving temperature up to 80 °C in cw operation. Lifetime was estimated to be over 5000 h with an optical output power of 5 mW at 80 °C in 515–518 nm LDs from 1000 h operation, and was estimated to be over 10,000 h with an output power of 60 mW at 60 °C in 488 nm LDs from 2000 h operation.
A New Cationic Gemini Surfmer: Synthesis and Surface Activities
Authors: Su Xin , Wang Biqing , Lu Zhiyong , Wei Limin , Feng Yujun
Published: May 2010

A new cationic gemini surfmer (polymerizable surfactant or surface‐active monomer) with an acrylic reactive group in its spacer group was synthesized and characterized, and its surface activity properties were examined in comparison with its intermediate surfactant 12‐3OH‐12·2Cl−, a previously‐reported gemini surfmer 12′‐2‐12′·2Br−, as well as monomeric surfactant dodecyl trimethylammonium bromide. It was found that neither the incorporation of a double bond onto the gemini surfactant nor the change of location of the double bond will affect surface activities of the gemini surfactant.
Body image and first sexual intercourse in late adolescence
Authors: Vasilenko Sara A. , Ram Nilam , Lefkowitz Eva S.
Published: May 2010

Sexual behavior is associated with body image, but the directionality of this association is unclear. This study used longitudinal data from a sample of previously abstinent college students (N = 100, 45% female, 49% European American, 26% Latino American, 25% African American) to test whether satisfaction with appearance changed after first intercourse. Male students were more satisfied with their appearance after first intercourse, whereas female students became slightly less satisfied with their appearance. These findings demonstrate that first intercourse can lead to changes in well‐being, even if the transition takes places in late adolescence. In addition, they suggest that gendered cultural expectations regarding sexual behavior are associated with differing psychological outcomes for male and female adolescents.
Brief report: “I can't talk about it:” Sexuality and self‐silencing as interactive predictors of depressive symptoms in adolescent dating couples
Authors: Little Katherine C. , Welsh Deborah P. , Darling Nancy , Holmes Rachel M.
Published: May 2010

This longitudinal study examined sexual intercourse within adolescent romantic relationships as a couple‐level moderator of the association between adolescent individual characteristics and depressive symptoms. Two hundred nine middle‐ and older‐adolescent dating couples (aged 14–17 and 17–21, respectively) reported on their own self‐silencing, depressive symptoms, and sexual behaviors. At Time 1, frequency of sexual intercourse significantly moderated the relationship between self‐silencing and depressive symptoms, such that adolescents higher in self‐silencing engaging in more frequent sex were at risk for clinically significant levels of depression. Adolescents who were low in self‐silencing were not at increased risk for depression, regardless of frequency of sex. Self‐silencing also significantly predicted increases in depressive symptoms from Time 1 to Time 2. Implications include the possibility that frequent sex in highly self‐silencing adolescents exacerbates psychological depletion believed to link self‐silencing to depressive symptoms, and that this depletion compounds over time.
Classification and identification of opioid addiction in chronic pain patients

Published: May 2010

Addiction is a feared consequence of long‐term opioid treatment of chronic pain patients. The ICD‐10 and DSM‐IV diagnostic addiction criteria may not be appropriate in these patients. Therefore Portenoy's criteria (PC) were launched. The aim was to estimate the prevalence of addiction, to investigate whether PC were applicable and to compare these criteria with the ICD‐10 criteria. The study was cross‐sectional and included 253 patients with chronic pain at a tertiary pain centre. Patients were screened for addiction by a physician and a nurse. The addiction prevalence was 14.4% according to ICD‐10 and 19.3% according to PC. A significant difference between the prevalence of addiction according to ICD‐10 and to PC was found. The inter‐rater reliability was 0.95 for ICD‐10 and 0.93 for PC. The sensitivity of PC was 0.85 and the specificity was 0.96. According to PC patients classified as addicted were treated with significantly higher opioid doses, drank more alcohol, smoked more tobacco, used benzodiazepines and had higher levels of depression. According to ICD‐10 patients classified as addicted used higher doses of opioids, drank more alcohol and had higher scores of anxiety and depression. High opioid doses, concomitant use of alcohol and younger age were risk factors. The risk profile for PC was different to ICD‐10 by adding risk factors as concomitant use of benzodiazepines, having depression and low educational level. PC seems to be appropriate for diagnosing addiction in opioid treated pain patients and seems to be more sensitive and specific than ICD‐10 criteria.
