BACKGROUNDPatients with incurable cancer face many physical and emotional stressors, yet little is known about their coping strategies or the relationship between their coping strategies, quality of life (QOL), and mood.METHODSAs part of a randomized trial of palliative care, this study assessed baseline QOL (Functional Assessment of Cancer Therapy–General), mood (Hospital Anxiety and Depression Scale), and coping (Brief COPE) in patients within 8 weeks of a diagnosis of incurable lung or gastrointestinal cancer and before randomization. To examine associations between coping strategies, QOL, and mood, we used linear regression, adjusting for patients' age, sex, marital status, and cancer type.RESULTSThere were 350 participants (mean age, 64.9 years), and the majority were male (54.0%), were married (70.0%), and had lung cancer (54.6%). Most reported high utilization of emotional support coping (77.0%), whereas fewer reported high utilization of acceptance (44.8%), self‐blame (37.9%), and denial (28.2%). Emotional support (QOL: β = 2.65, P < .01; depression: β = –0.56, P = .02) and acceptance (QOL: β = 1.55, P < .01; depression: β = –0.37, P = .01; anxiety: β = –0.34, P = .02) correlated with better QOL and mood. Denial (QOL: β = –1.97, P < .01; depression: β = 0.36, P = .01; anxiety: β = 0.61, P < .01) and self‐blame (QOL: β = –2.31, P < .01; depression: β = 0.58, P < .01; anxiety: β = 0.66, P < .01) correlated with worse QOL and mood.CONCLUSIONSPatients with newly diagnosed, incurable cancer use a variety of coping strategies. The use of emotional support and acceptance coping strategies correlated with better QOL and mood, whereas the use of denial and self‐blame negatively correlated with these outcomes. Interventions to improve patients' QOL and mood should seek to cultivate the use of adaptive coping strategies. Cancer 2016;122:2110–6. © 2016 American Cancer Society.

AbstractBackgroundLocking reconstruction plates are used in the treatment of jaw trauma and diseases if there is a need for surgical resection and to prevent pathologic fracture after tumor excision. Fixation is typically performed using an extraoral approach.MethodsThis article describes a technique for the intraoral fixation of locking reconstruction plates that uses prototyping to model the plate before the procedure as well as an implant handpiece with adapted drills for bone drilling and the insertion of screws into relatively inaccessible areas.ConclusionIntraoral fixation not only prevents nerve damage and facial scarring but also minimizes the plate's risk of extraoral exposure and reduces surgical morbidity. © 2016 Wiley Periodicals, Inc.

Assessment of Climate Change Impacts on the Future Hydrologic Cycle of the Han River Basin in South Korea Using a Grid‐Based Distributed Model
Authors: Ahn So Ra , Kim Seong Joon 
Published: April 2016

AbstractThe purpose of this study is to assess the impacts of climate change on the hydrologic cycle of the Han River Basin in South Korea using the Projection of Hydrology via the Grid‐based Assessment for Climate Change (PGA‐CC) model. PGA‐CC is a physically based continuous, long‐term, distributed model. The model was calibrated and validated using 9 years (2001–2009) of inflow data from two sub‐basins to reservoirs (the Chungju Reservoir and Soyang Reservoir) in the Han River Basin with a 4 km spatial resolution. The average Nash–Sutcliffe model efficiencies of the Chungju and Soyang reservoirs were 0.57 and 0.71, and the average coefficients of determination were 0.65 and 0.72, respectively. The applicability of the PGA‐CC model was tested by assessing the future river basin hydrology with the HadGEM3‐RA AR5 4.5 and 8.5 climate change scenarios. The annual total discharge from the RCP 4.5 scenario in the 2080s showed a change of up to +33.0% based on the 1070 mm yr−1 value from the baseline period (1980–2009) due to a +28.1% increase in precipitation. The annual evapotranspiration from the RCP 8.5 scenario showed an increase of up to 46.2% compared to the baseline period of 357 mm yr−1 due to a temperature increase of 5.4 °C.

Published: April 2016

AbstractDigital curation provides a way to transcend traditional academic fields of study and create instructional materials available to support adolescent and adult literacy initiatives. The instructional capabilities that Web 2.0 tools offer provide curators with the ability to reach audiences in a way that has not been possible in the past. The authors propose a digital curation framework for teachers to use as they collect, categorize, critique, conceptualize, and circulate resources. Based on this framework, the authors identify 10 valuable Web 2.0 tools that are available for effective content literacy digital curation.
From Keats to Kanye: Romantic Poetry and Popular Culture in the Secondary English Classroom
Authors: Bowmer Megan E. , Curwood Jen Scott 
Published: April 2016

AbstractThis case study examined a Romanticism unit within a Year 9 English class in Sydney, Australia. It considered whether popular culture could build connections between students’ lives and Romanticism, and whether the process of remixing ‘high’ Romantic poetry with ‘low’ popular culture could foster student engagement. Thematic analysis of interview, survey, observation, and artifact data revealed three key findings. Firstly, through exploring popular culture texts, students believed Romantic concepts related to their world but not to them. Secondly, the extent to which students understood Romanticism through popular culture was influenced by personal, textual, and educational factors. Thirdly, students felt that the collaborative remixing process promoted freedom of expression. While many teachers are concerned that popular culture will displace canonical literature, this study found that this is not the case: incorporating popular culture is not an ‘either/or’ approach, but it is an enriching, complementary practice.

Published: April 2016

AbstractWear testing of total joint replacement (TJR) is mandatory in preclinical testing before implantation of TJR into the human body. Testing is governed by current international standards that recommend bovine serum (BS) as a lubricating fluid to replace synovial fluid (SF). Recently, the use of BS has been criticized because of differences in content, fluid characteristics, and nonhuman origin. As a result, a more realistic lubricant mimicking SF is needed. To define SF composition, we analyzed SF obtained during revisions of total hip and knee arthroplasties and compared it with SF obtained during primary arthroplasties and from patients without TJR. Samples were acquired from 152 patients. We found that the median total protein concentration for all SF was 36.8 mg/mL, which is significantly higher than concentrations currently recommended by the ISO standards. The γ‐globulin concentration was significantly higher and the phospholipid concentration significantly lower in patients with revision of TJR compared with patients without TJR. No significant difference was found in hyaluronic acid concentration and viscosity among the groups. Our results support the need to improve the definition of a more clinically relevant wear testing lubricant in the ISO standards. © 2016 Wiley Periodicals, Inc.

Published: April 2016

ObjectiveInflammation is a potential mechanism of obstructive sleep apnea syndrome (OSAS). Thymosin β4, a member of thymic protein family, exhibits an anti‐inflammatory effect. We determine to investigate whether serum thymosin β4 concentrations is correlated with the occurrence and disease severity of OSAS.MethodsSerum thymosin β4 concentrations were examined in a cross‐sectional population including 158 patients with OSAS and 94 healthy subjects.ResultsElevated serum thymosin β4 concentrations were found in OSAS patients than the controls. Multivariable logistic regression analysis indicated a significant association between serum thymosin β4 concentrations and OSAS development. Severe OSAS patients showed increased serum thymosin β4 concentrations compared with mild and moderate patients. Spearman correlation analysis suggested that serum thymosin β4 concentrations were correlated with the severity of OSAS. Simple linear regression analyses showed that serum thymosin β4 in OSAS patients was correlated with homeostasis model assessment of insulin resistance, apnea hypopnea index, disease severity, and osteoarthritis development. Then multiple stepwise regression analysis showed that only disease severity remained to be associated with serum thymosin β4.ConclusionsSerum thymosin β4 concentrations were correlated with the occurrence and severity of OSAS.

For achieving velocities and image quality comparable to data from a single acceptance window, but higher gating efficiency, selected motion‐corrected TPM () can be applied. J. Magn. Reson.

Love Is Blind: How Our Love for More Choice Costs Time
Authors: Rogge Nicky 
Published: April 2016

ABSTRACTThe paper applies a multilevel modeling approach in the study of individual behavior in choice experiments. The purpose is to study the relationship between choice time and several features of the choice task such as the number of choice alternatives, amount of choice information, and (dis)similarity of the choice alternatives. A special focus is on the difference in choice time between individuals who frequently maximize in choice making and their counterparts who are habitually satisficing. In total, 15 choice experiments were conducted (three versions of choice experiments for five different choice stimuli: restaurant, holiday resort hotel, smartphone, job, and project partner). The results show that choice time increases as choice tasks are more complex. As to the people's maximizing tendency, no significant differences in choice time are found between maximizers and satisficers.

ObjectiveTo assess the effect of pre‐pregnancy body mass index (BMI), gestational weight gain (GWG), and other maternal factors on the timing of adiposity rebound (AR).MethodsIn this study, 594 mothers (mothers who do not have diabetes and not underweight) from the longitudinal Growth and Obesity Chilean Cohort Study self‐reported their weights at the beginning and end of their pregnancies, and their heights were measured. Pre‐pregnancy BMI was categorized as normal weight, overweight, or obesity, and GWG was assessed according to Institute of Medicine guidelines. For children, weight and height measurements from 0 to 3 years were retrieved from records, and they were measured from age 4 to 7 years. BMI curves from 0 to 7 years were used to estimate the age at AR, which was categorized as early (<5 years), intermediate (5‐7 years), or late (>7 years). The associations between pre‐pregnancy BMI and GWG and early AR were tested using logistic regression models.ResultsIn total, 33% of the mothers had excess pre‐pregnancy weight, 31.2% exceeded Institute of Medicine recommendations, and 45% of children had early AR. The pre‐pregnancy BMI and parity were associated with earlier AR (OR = 1.07, 95% CI = 1.02‐1.11; OR = 0.86; 95% CI = 0.74‐0.99, respectively), but GWG was unrelated.ConclusionsThese results suggest that preventive strategies for promoting normal pre‐pregnancy BMI, especially in women's first pregnancies, could delay the timing of AR, with protective metabolic effects on offspring.

ABSTRACTTo extensively explore the influence of anion structure on the physical properties of poly(ionic liquid)s (PILs) a series of PILs having main‐chain 1,2,3‐triazolium cations was synthesized via copper(I)‐catalyzed azide‐alkyne 1,3‐dipolar cycloaddition (CuAAC) followed by N‐alkylation with iodomethane and anion metathesis with different metal salts, that is, Li(CF3SO2)2N, Li(CF3CF2SO2)2N, K(FSO2)2N, K(CF3SO2)N(CN), Ag(CN)2N, and sodium 4,5‐dicyano‐1,2,3‐triazolate. To isolate the effect of anion on physical properties of PILs, a common iodide precursor was used to maintain constant the average degree of polymerization (DPn) and chain dispersity. Detailed structure/properties relationship analyses demonstrated a lack of correlation between anion chemical structure, ionic conductivity, and glass transition temperatures. Among synthesized series, the PIL derivative having bis(trifluoromethylsulfonyl)imide counter anion showed the best compromise in performance: low glass transition temperature (Tg = −68 °C), high thermal stability (Tonset = 340 °C) and superior ionic conductivity (σDC = 8.5 × 10− 6 S/cm at 30 °C), which makes it an interesting candidate for various key modern electrochemical applications. © 2016 Wiley Periodicals, Inc.

Generalized Method for Gun Propellant Formulation Design
Authors: Sudarsan Nanduri V. , Das Samir K. , Naik Smita D. 
Published: April 2016

AbstractDetermination of propellant formulation by ballistic requirement is an important area of research in recent times. In this study, a theoretical method for the design of gun propellant formulation using primary data of ingredients and necessary thermochemical properties of the resultant propellant was established. The employed method is based on a mathematical model of thermochemical properties of the propellant by optimizing the heat of explosion of the propellant using the fmincon tool in MATLAB. A graphical user interface (GUI) based code was generated and developed for the formulation design of solid gun propellants. The designed code was verified by available data in the literature. Such code will be useful to the researchers working in the area of high energy materials for the design of unknown propellant compositions. Further, it can be extended to redesign the existing propellant formulation in order to enhance the ballistic performance.
Behavioural interactions between the lizard Takydromus tachydromoides and the praying mantis Tenodera aridifolia suggest reciprocal predation between them

Abstract
The Japanese lacertid lizard Takydromus tachydromoides and the praying mantis Tenodera aridifolia are sympatric generalist predators feeding on similar prey. To confirm reciprocal predation between them, we observed the behavioural interactions between the lizards and the mantises of different sizes in a laboratory condition. The lizards caught small mantises (from first to fifth instars), but sometimes escaped from large mantises (from sixth instar to adult). Large mantises occasionally showed catch responses to the lizards. The lizards sometimes caught the mantis without a tongue-flick response (sampling of chemical cues), and they sometimes did not catch the small mantises showing immobile or cryptic responses that prevent visual detection. These results suggested the primary role of vision on recognition of the mantis as a prey. The lizards spent a longer time to approach larger mantises. The time from orienting to catch was longer when the lizards showed tongue-flick responses. The lizard also spent a longer time before deciding to escape from the mantis than to catch it. Biological significance of these differences in timing was discussed.

AbstractAdelges tsugaeinfested western hemlock trees were sampled periodically for 1 year at two locations in Oregon and Washington to compare the phenology and abundance of three associated predators (Leucopis argenticollis, Leucopis piniperda, andLaricobius nigrinus) and their host. On each sample date, two 3–10 cm long terminal twigs were collected from each tree and brought to the laboratory to count all life stages ofA. tsugaeand the three predators. Peak larval abundance ofLeucopisspp. andLa. nigrinuscoincided with the presence ofA. tsugaeadults and eggs.Leucopisspp. larvae were present for a much longer period of time than wereLa. nigrinuslarvae. Furthermore,Leucopisspp. larvae were present during both the progrediens and sistens egg stages, whileLa. nigrinuslarvae were only present during the progrediens egg stage. Overall, we collected 2.3–3.5 times moreLeucopisspp. of all life stages thanLa. nigrinus. These results support the continued study ofLeucopisspp. from the Pacific Northwest as biological control agents forA. tsugaein the Eastern USA.
Effect of intratympanic steroid administration on sensorineural hearing loss associated with acute otitis media
Authors: Heywood R L , Ifeacho S N , Narula A A 
Published: April 2016

AbstractObjective:To evaluate a small cohort of patients who presented with symptoms and signs consistent with acute infective sensorineural hearing loss who were treated with intratympanic steroids.Method:Seven patients received a 7-day course of oral antibiotics and oral prednisolone followed by 3 intratympanic injections of methylprednisolone and 1 week of topical dexamethasone drops.Results:Hearing improved in 57 per cent of patients (four out of seven). The mean improvement in this group was 24 dB (range, 10–52 dB). The magnitude of the sensorineural hearing loss at presentation was less in those who responded to intratympanic steroid therapy than in non-responders (mean pure tone average of 30 dB versus 65 dB pre-intratympanic steroids, and 14 dB versus 83 dB post-intratympanic steroids, respectively).Conclusion:The results of our study suggest that intratympanic steroids provide a valuable contribution to the treatment of acute infective sensorineural hearing loss and may provide additional benefit by virtue of a concentrated local steroid effect in patients who do not respond to antibiotics.
