Special education teachers' nature of science instructional experiences
Authors: Mulvey Bridget K. , Chiu Jennifer L. , Ghosh Rajlakshmi , Bell Randy L. 
Published: January 2016

AbstractSpecial education teachers provide critical science instruction to students. However, little research investigates special education teacher beliefs and practices around science in general or the nature of science and inquiry in particular. This investigation is a cross‐case analysis of four elementary special education teachers' initial semester‐long professional development experiences learning about and attempting to implement nature of science and inquiry instruction. Participants were purposively selected from a larger study of 61 pre‐K–5 teachers from one mid‐Atlantic urban school district. Data sources included pre/postsurveys, video recordings of lessons, teachers' guided reflections through time, and a postcourse interview. Results demonstrated that all participants improved their nature of science conceptions, explicitly addressed nature of science tenets during instruction, and taught via inquiry. Further, they moved beyond simply mimicking course lessons they experienced by adapting them to student needs and even innovating new lessons. Teachers increased their attention to plans and instruction to meet the needs of students with special needs; yet most of the teachers made few references to specific Individualized Education Programs, individual student needs, or associated instructional decisions. Results suggest that nature of science and inquiry professional development can increase special education teachers' expectations of their students with special needs. To improve outcomes, professional development should increase the explicit attention to planning and strategies to help meet specific student needs. Also, special and general education teachers in inclusion settings can benefit from support with the negotiation of their roles. © 2016 Wiley Periodicals, Inc. J Res Sci Teach 53: 554–578, 2016
A faulty node detection scheme for wireless sensor networks that use data aggregation for transport
Authors: Artail Hassan , Ajami Abdelkarim , Saouma Tania , Charaf Malak 
Published: January 2016

AbstractThis paper presents a faulty node detection approach for wireless sensor networks that aggregate measurement data on their way toward the sink (base station). The approach is based on the idea of commanding sensor nodes on the aggregation paths to temporarily stop including their readings in the received aggregated readings from their upstream neighbors. The scheme is dependent on the ability of the sink to detect faulty nodes through changes in the received aggregated readings at the sink using a Markov Chain Controller (MCC). The algorithm that is run in the sink uses the MCC to assign a state to each sensor node based on transitions that are triggered by receiving aggregated path readings, and accordingly deduces the nodes that may be faulty. The experimental results show at least 98% detection rate at the cost of reasonable detection delays and generated wireless network traffic. Copyright © 2016 John Wiley & Sons, Ltd.

Published: January 2016

AbstractBackgroundA large proportion of follicular thyroid carcinoma (FTC) patients in developing countries present with overt skeletal metastases (SM). These patients often require surgical interventions for prevention of morbidity, palliation of symptoms, and facilitation of radioiodine therapy (RAIT). Scarce literature is available about the long‐term outcome of such patients. The aim of this study was to evaluate the long‐term outcome of FTC patients undergoing surgical intervention for SM.MethodsWe retrospectively reviewed the data of FTC patients with SM (January 1990–December 2011). Out of 91 patients with SM, 32 had surgical interventions for SM. All had total thyroidectomy performed.ResultsThe mean age of the patients was 48.5 years (M:F = 1:2). Majority (93.7 %) had synchronous metastases and 22 % had multiple SM. The surgical interventions for SM included: laminectomy (50 %), resection of skull metastases (18.8 %), resection of manubrium sterni (18.8 %), partial clavicle excision (9.4 %), and hemimandibulectomy (3.1 %). The main intents were palliation (50 %) and facilitation of RAIT (37.5 %). 84 % patients received RAIT. Median follow‐up was 52 months (mean = 50 ± 37). Five‐ (56 vs 63 %) and 10‐year (28 vs 23 %) overall survival (OS) did not differ significantly (p = 0.968) from those not having interventions for SM. On univariate analysis tumor invasion (p = 0.006) and synchronous presentation of SM (p = 0.043) were significant risk factors for OS, whereas on multivariate analysis tumor invasion (p = 0.006) was significant.ConclusionsSurgical interventions directed at SM in FTC patients with overt multiple SM might not result in improve OS. However, considering reasonable long‐term survival, interventions should be considered for desired palliation and preservation of body function.

Published: January 2016

AbstractLandscape heterogeneity has been shown to be a major factor in the maintenance of biodiversity and associated services in agricultural landscapes. Farmlands are mosaics of fields with various crop types and farming practices. Crop phenology creates asynchrony between fields sown and harvested in different periods (winter vs. spring crops). The present study was conducted to examine the influence of such spatio‐temporal heterogeneity on biodiversity, with the hypothesis that it would lead to spatio‐temporal redistribution (shifting) of species. Species richness and activity‐density of carabid beetles in winter cereal (winter) and maize (spring) crops were compared across 20 landscapes distributed along a double gradient of relative area and spatial configuration of winter and spring crops. Maize fields were sampled in spring and late summer for comparison over time. The response of carabid species richness to landscape heterogeneity was weak in spring, but maize field richness benefited from adjacencies with woody habitat, in late summer. In spring, increased length of interfaces between winter and spring crops lowered carabid activity‐density in winter cereal fields, suggesting that maize fields acted as sinks. Interfaces between woody habitats and crops increased activity‐density in both crop types. We found no evidence of spatio‐temporal complementation, but different species benefited from winter cereals and maize in spring and late summer, increasing overall diversity. These findings confirm the role of adjacencies between woody and cultivated habitats in the conservation of abundant carabid assemblage in winter cereals and maize. We conclude that between‐field population movement occurs, and advocate for better consideration of farmland heterogeneity in future research.

AbstractNew surgical techniques and technology have simplified laparoscopic hysterectomy and have enhanced the safety of this procedure. However, the surgical colpotomy step has not been addressed. This study evaluates the surgical colpotomy step in laparoscopic hysterectomy with respect to difficulty and duration. Furthermore, it proposes an alternative route that may simplify this step in laparoscopic hysterectomy. A structured interview, a prospective cohort study, and a problem analysis were performed regarding experienced difficulty and duration of surgical colpotomy in laparoscopic hysterectomy. Sixteen experts in minimally invasive gynecologic surgery from 12 hospitals participated in the structured interview using a 5-point Likert scale. The colpotomy in LH received the highest scores for complexity (2.8 ± 1.2), compared to AH and VH. Colpotomy in LH was estimated as more difficult than in AH (2.8 vs 1.4, p < .001). In the cohort study, 107 patients undergoing LH were included. Sixteen percent of the total procedure time was spent on colpotomy (SD 7.8 %). BMI was positively correlated with colpotomy time, even after correcting for longer operation time. No relation was found between colpotomy time and blood loss or uterine weight. The surgical colpotomy step in laparoscopic hysterectomy should be simplified as this study demonstrates that it is time consuming and is considered to be more difficult than in other hysterectomy procedures. A vaginal approach to the colpotomy is proposed to achieve this simplification.

Published: January 2016

AbstractLandscape disturbances can affect reproductive performance of animal‐pollinated trees. We verified the effects of the loss and fragmentation of natural forests caused by the creation of coniferous plantations on fruit and seed production as well as mating patterns of animal‐pollinated trees. We investigated 146 and 134 individual flowering trees of Prunus verecunda (Koidz.) Koehne in 2012 and 2013, respectively, at 12 sites. These sites were at least 1.2 km apart from each other in an 8 × 15‐km forestry region, and the composition and configuration of natural forests varied in the study area. The mean outcrossing rate was >0.99 across the sites. Among trees within the sites, the number of fruits per inflorescence was positively correlated with the basal stem area and leaf chlorophyll density of the trees. Among the sites, the mean number of fruits per inflorescence was positively correlated with the site elevation, and the correlated paternity was positively correlated with the mean distance between trees. The sound‐seed rate was positively correlated with the natural‐forest area among the sites. These results suggest that environments and resources of trees influence their fruit production, that a loss of natural forests increases in embryo mortality, and that a reduction in tree density decreases pollen donor diversity in P. verecunda. Thus, a landscape disturbance may decrease seed production, whereas outbreeding is maintained, and fruit production is not likely to be dependent on the landscape disturbance in this species.

AbstractFishery sustainability and the extinction risk of the Japanese eel, Anguilla japonica, are of global concern. The landings of the Japanese eel in Japan comprise a large part of the landings in East Asia. This study provides a compiled dataset of the annual fisheries statistics of the Japanese eel in Japan for stock assessment. The Japanese government has been recording Japanese eel statistics annually since 1984 in five series of annual reports by conducting systematic questionnaire surveys of fisheries managers and associations; however, most of these data are stored in analog format. The key variables in the dataset include the harvest weight of eels, the harvest weight and number of seeds for aquaculture, the number of eels stocked, and the number of management entities engaged in the eel fishery. The levels of spatial aggregation of the variables include the site (river and lake), prefecture, inland and coastal waters, and total in Japan. We also incorporated location data (latitude and longitude) of the site and prefecture into the dataset. Eel harvest includes primarily yellow eels (late juvenile stage) and silver eels (mature stage). Seed harvest in inland waters includes glass eels (intermediate stage between leptocephalus and elver) and elvers (early juvenile stage). Seed harvest from coastal waters comprises glass eels. This dataset provides information to assess long‐term trends in the Japanese eel population.

Published: January 2016

AbstractAmmoxidation of acrolein to acrylonitrile was studied using multicomponent (MC) BiMoOx catalysts in the presence of ammonia and oxygen. The MC catalysts containing bivalent and trivalent metal promoters were found to be highly active and selective to acrylonitrile. The corresponding MC catalysts were characterized by X‐ray diffraction, nitrogen physisorption, X‐ray photoelectron spectroscopy, ICP‐MS and UV–visible diffuse reflectance spectroscopy. It was observed that, among the bivalent cations, the catalysts containing both Co–Ni showed superior performances due to the presence of the metastable β‐CoxNi1−xMoO4 phase. The presence of a trivalent cation, and especially of iron, promoted the formation of both the γ‐Bi2MoO6 active phase and the active β‐phase of bivalent metal molybdate. Further, optimization of the reaction conditions enabled the achievement of a 59 % acrylonitrile yield.

Abstract

Background
The clinical course of bicuspid aortic valves (BAVs) is variable. Data on predictors of aortopathy and valvular dysfunction mainly focus on valve morphology.

Aim
To determine whether the presence and extent of the raphe (fusion site of valve leaflets) is associated with the degree of aortopathy and valvular dysfunction in patients with isolated BAV and associated aortic coarctation (CoA).

Methods
Valve morphology and aortic dimensions of 255 BAV patients were evaluated retrospectively by echocardiography.

Results
BAVs with a complete raphe had a significantly higher prevalence of valve dysfunction (especially aortic regurgitation) than BAVs with incomplete raphes (82.9 vs. 66.7 %, p = 0.01). Type 1A BAVs (fusion of right and left coronary leaflets) and complete raphe had larger aortic sinus diameters compared with the rest of the population (37.74 vs. 36.01, p = 0.031). Patients with CoA and type 1A BAV had significantly less valve regurgitation (13.6 vs. 55.8 %, p < 0.001) and smaller diameters of the ascending aorta (33.7 vs. 37.8 mm, p < 0.001) and aortic arch (25.8 vs. 30.2 mm, p < 0.001) than patients with isolated BAV.

Conclusions
Type 1A BAV with complete raphe is associated with more aortic regurgitation and root dilatation. The majority of CoA patients have incomplete raphes, associated with smaller aortic root diameters and less valve regurgitation.
Self‐perceptions of pubertal timing and patterns of peer group activities and dating behavior among heterosexual adolescent girls
Authors: Carter Rona , Williams Sandra 
Published: January 2016

ABSTRACTThis study identified patterns of past and concurrent peer group and dating behavior in a sample of adolescent girls (N = 511; aged 17–19 years; 49% White). Peer group activities and dating behaviors were classified as occurring in either early (ages 10–13 years), middle (ages 14–16 years), or late (ages 17–19 years) adolescence according to the age at which each participant indicated the activity/behavior was first experienced. Latent class analysis identified four latent classes: Early Interactions/Early Daters (15%), Early Interactions/Late Daters (17%), Early Interactions/Middle Daters (33%) and Middle Interactions/Middle Daters (35%). Class membership was associated with girl's perceived pubertal timing. Compared to Early Interactions/Early Daters, girls in the Early Interactions/Late Daters class reported higher levels of pubertal timing, indicating greater perception that their pubertal development was late relative to peers. Late perceived pubertal timing is potentially relevant for dating but not necessarily other mixed‐ and cross‐sex peer interactions.

Background/Objective The aim of this study was to examine the reliability and validity of the Chinese version of the School Function Assessment (SFA) for primary school students with cerebral palsy (CP) in Guangzhou, China. Methods Ninety-three students with CP were recruited by convenience sampling from a special school. The Chinese version of the SFA was administered and an exploratory factor analysis with direct oblique rotation was used to extract the factor structure underlying the Activity Performance scales of the SFA. An intraclass correlation one-way random single measure was performed to study external reliability. Cronbach's alpha was used to study internal consistency. Results The findings showed that the Chinese version of the SFA had high internal consistency with test–retest reliability [ICC (1, k) = 0.49–0.97]. Conclusion This study has established the applicability of the SFA for both clinical and research purposes in the Chinese population, and presented evidence of satisfactory psychometric properties in use with primary school students with CP in special schools.
DETERMINANTS OF DECISIONS TO ENTER THE U.S. FARMING SECTOR
Authors: MISHRA ASHOK K. , EL-OSTA HISHAM S. 
Published: January 2016

AbstractThis study investigates the factors likely to affect an individual’s decision to enter farming after and/or while participating in an off-farm employment activity. Additionally, an ordered multivariate regression procedure was used to analyze the degree of importance of selected motivating reasons that were drivers of individuals’ decision to enter farming. Results indicate that individuals with lower education, children in the household, and older family members were more likely to have entered farming as an occupation. Findings further suggest that federal policies in the form of farm program payments may provide retired nonfarm workers incentives to enter farming in later life.
A Reassessment of the Routine Pretreatment Protocol for Radiocarbon Dating Cremated Bones
Authors: Snoeck Christophe , Staff Richard A , Brock Fiona 
Published: January 2016

AbstractIn the late 1990s, it was demonstrated that reliable radiocarbon dates could be obtained directly from cremated bone. Many 14C laboratories have since used a protocol for pretreating cremated (calcined) bones that consists of consecutive treatments with bleach and acetic acid to remove organic matter and extraneous or diagenetic carbonate, respectively. In most instances, the bleach used is sodium hypochlorite, although in recent years the Oxford Radiocarbon Accelerator Unit (ORAU) has used acidified sodium chlorite instead. However, properly calcined (white) bones should not contain any organic material; hence, the bleach treatment is potentially unnecessary. This article describes studies investigating the effectiveness of bleach (and the specific bleach used) during pretreatment of calcined bone, and demonstrates that 14C dates on six cremated bone samples are statistically indistinguishable whether or not the initial bleach step is applied.
Rapid Quantification of Bone Collagen Content by ATR-FTIR Spectroscopy

Published: January 2016

AbstractExpensive and time-consuming preparation procedures for radiocarbon and stable isotope analyses can be conducted on archaeological bone samples even if no collagen is preserved. Such unsuccessful preparation can lead to the partial destruction of valuable archaeological material. Establishing a rapid prescreening method for evaluating the amount of bone collagen while minimizing the impact of sampling constitutes a challenge for the preservation of archaeological collections. This study proposes and discusses a new methodology to detect and quantify collagen content in archaeological bone samples by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. A total of 42 Pleistocene to modern bone samples were selected according to their nitrogen content measured using an elemental analyzer. Comparison of collagen content estimation using ATR-FTIR and mass spectrometry reveals that some of the studied samples are contaminated by a nitrogen source coming from the burial environment. Two different FTIR calibration approaches were tested on the uncontaminated samples: peak-to-peak ratio and multivariate regression (PLS). The two approaches yield similar results with a good correlation of ATR-FTIR analyses and N wt% from 0.7 to 4wt% (R²=0.97–0.99; standard error of estimation ±0.22 to 0.25wt%). While collagen content remains difficult to detect in poorly preserved bones (less than ~3wt%), ATR-FTIR analysis can be a fast alternative for sample screening to optimize the sampling strategy and avoid partial destruction of valuable samples that do not contain enough collagen for further analysis.
Time History of a Human Kidney Stone Determined by Bomb-Pulse Dating
Authors: Levchenko Vladimir A , Williams A Alan 
Published: January 2016

AbstractAn in vivo grown human kidney stone was dated using the atmospheric bomb pulse. The growth period was found to be 17.6 yr for a sample size of 6 mm across. The step dissolution method was used, as one of several possibilities, to produce depositional subsamples. A noticeable dead carbon presence is detected in the modern industrialized diet, and as a consequence in human metabolites. The importance for correction when applying bomb-pulse dating is noted.
