A Multiyear Population-Based Study of Kindergarten Language Screening Failure Rates Using the Rice Wexler Test of Early Grammatical Impairment
Authors: Weiler Brian , Schuele C. Melanie , Feldman Jacob I. , Krimm Hannah 
Published: April 2018

Purpose
The purpose of this study was to evaluate, over 2 separate school years, the school-district-wide failure rate of kindergartners on a screener of grammatical tense marking—the Rice Wexler Test of Early Grammatical Impairment (TEGI) Screening Test (Rice & Wexler, 2001)—composed of past tense (PT) and third-person singular (3S) probes.

Method

In the fall of 2 consecutive school years, consented and eligible kindergartners (
n
= 148 in Year 1,
n
= 126 in Year 2) in a rural southern school district were administered the TEGI Screening Test. Children who failed the screening test or either of the individual probes (PT or 3S) were administered the Primary Test of Nonverbal Intelligence. All children also completed the Test of Articulation Performance–Screen (Bryant & Bryant, 1983) and, in Year 2, the Get Ready to Read! emergent literacy screener (Whitehurst & Lonigan, 2001).

Results
The screening tool outcome most closely and consistently aligned with the recommended failure rate of approximately 30% (Oetting, Gregory, & Rivière, 2016; based on Tomblin et al., 1997) was the TEGI PT probe. TEGI Screening Test and 3S probe failure rates fell below the recommended level. Most children who failed the PT probe demonstrated nonverbal intelligence skills within the average range. In addition, most children who failed the PT probe would not have been readily identified on the basis of only the results of their articulation or emergent literacy screenings.

Conclusions
The TEGI PT probe is an efficient and reliable screener that identifies children for monitoring or additional language assessment. Children with language vulnerabilities are not necessarily identified by articulation or emergent literacy screenings at entry to kindergarten. To identify children at risk for language impairment, it is therefore necessary to directly screen oral language.
A Preliminary Examination of Concussion Knowledge by Collegiate Athletes and Non-Athletes
Authors: Knollman-Porter Kelly , Brown Jessica , Flynn Madelaine 
Published: April 2018

Purpose
Concussions affect various populations, including collegiate athletes and non-athletes. The purpose of this study was to compare collegiate varsity athletes, recreational athletes, and non-athletes' knowledge of concussion definition, symptoms, and support services available following injury. Preferred method of concussion education delivery was also examined.

Method
We surveyed 306 current college students using an online survey system. The survey included free recall and forced-choice question formats. Quantitative analyses were used to analyze results and compare responses among groups.

Results

Collegiate athletes and non-athletes demonstrate incomplete knowledge of concussion definition, related symptoms, and professionals involved in postinjury management. Varsity athletes rated self-knowledge of concussion parameters significantly higher than the other groups (
p
< .001), though few significant differences in actual knowledge levels were observed. Overall, respondents reported having the highest preference for concussion education delivered by medical professionals.

Conclusion
Knowledge concerning concussion is incomplete in the collegiate population. Varsity athletes' exposure to formal education did not result in higher knowledge levels compared with other groups. Further examination of concussion educational delivery models' effect on change in concussion-related behavior in this population is warranted.

Published: April 2018

PurposeThe purpose of this study was twofold: First, we replicated in a new sample our previous findings that a culturally and linguistically responsive (CLR) bilingual approach for English vocabulary instruction for preschool Latino dual language learners was effective. Subsequently, we investigated whether the positive effect of CLR instruction varies as a function of individual child characteristics, including baseline vocabulary levels and gender.MethodUsing a randomized pretest–posttest follow-up group design, we first replicated our previous study (N= 42) with a new sample by randomly assigning 35 Spanish-speaking Latino preschoolers to a CLR bilingual group or an English-only group. The preschoolers received small-group evidence-informed shared readings targeting 30 English words 3 times a week for 5 weeks in their preschools. Vocabulary outcomes were measured using both standardized and researcher-developed measures. We subsequently conducted further studies with the combined sample size of 77 children to examine the variability in intervention effects related to child gender and baseline vocabulary levels.ResultsThe direct replication study confirmed findings of our earlier work suggesting that the CLR bilingual approach promoted greater gains in L1 and L2 vocabulary than in an English-only approach. The extension studies revealed that the effect of the CLR bilingual vocabulary approach on English and Spanish vocabulary outcomes was not impacted by gender or vocabulary status at baseline.ConclusionThis study provides additional evidence of the benefits of strategically combining L1 and L2 for vocabulary instruction over an English-only approach. Our findings also suggest that preschool Latino dual language learners can benefit from a bilingual vocabulary instructional approach regardless of gender or baseline vocabulary levels in L1.

Published: April 2018

PurposeThe goal of the current study was to examine the impact of dialect density on the growth of oral language and reading skills in a sample of African American English (AAE)-speaking children reared in urban communities.MethodEight hundred thirty-five African American children in first through fifth grades participated. Using an accelerated cohort design, univariate and bivariate growth models were employed to examine dialect density, oral language and reading, and the relationships between these variables.ResultsFor the univariate models, results indicated that (a) dialect density decreased over time by approximately 5% per year beyond first grade, (b) language skills improved approximately 0.5SDper year, and (c) reading comprehension increased significantly from first to second grade and slowed 23% per year in second through fifth grades. Results from the bivariate models revealed that (a) dialect density and language ability are negatively associated, although dialect density did not affect change in language over time, and (b) higher dialect density is related to slower growth in reading.ConclusionsFindings from this investigation provide converging evidence for accounts in the extant literature particularly supporting a negative relationship between dialect density and oral language and between dialect density and reading while also contributing novel longitudinal evidence that suggests that changes in dialect use over time may be driven by oral language skills and that reading and dialect have a reciprocal relationship.
Boost–flyback converter with interleaved input current and output voltage series connection
Authors: Brockveld Sergio Luis , Waltrich Gierri 
Published: April 2018

This study proposed a high‐gain dc–dc converter with an interleaved current at the input stage and voltage series connection at the output stage. This converter was designed based on the boost–flyback topology, which has as main characteristic high voltage gain. Normally, the boost–flyback is designed with the low input voltage, and therefore, the current at this stage reaches high current values, limiting the converter design. Therefore, paralleling the input connection allows the current division between the semiconductors, reducing the switching stress. As part of the converter analysis, in this study, the static and the dynamic converter model are obtained to further design the converter controllers. Furthermore, simulations and experimental results for the proposed converter, operating in closed‐looping control, were designed for a peak power of 1.2 kW, reaching a maximum efficiency of 97.5%.

Published: April 2018

The ‘white pollution’ caused by expanded polystyrene (EPS) foam wastes has become a difficult problem in the world. In this study, the wasted EPS foam material was reused to prepare phase change material (PCM) in order to reduce its pollution to the environment. The phase separation method was adopted to build microencapsulated PCM and the paraffin wax was used as core material in this work. Their results showed that the impurities contained in polystyrene foam wastes almost had no impact on the samples. The particles had continuous surface and regular spherical structure. Compared to other PCMs, the latent heat of the PCM in this study is significantly increased, which is about 72.52 J/g. As mentioned above, the material prepared in this work can be considered as a potential phase change material.

Published: April 2018

Background Recipient vessels proximal to the zone of injury have traditionally been preferred for lower extremity reconstruction. However, more recent data have shown mixed outcomes when performing anastomoses distal to the zone of injury. We investigated the impact of recipient vessel location on free flap outcomes.
Methods Retrospective review (1979–2016); 312 soft tissue free flaps for open tibia fractures met inclusion criteria. Flap characteristics and perioperative outcomes were examined. Systematic review identified articles evaluating anastomosis location and flap outcomes; pooled data analysis was performed.
Results More anastomoses were performed proximal to the zone of injury (80.7%) than distal (19.3%). Distal anastomoses were not associated with increased take back rates (19.6%) compared with proximal (23.8%) anastomoses (p = 0.356). Regression analysis comparing proximal and distal anastomoses found no difference in partial flap failures (7.4% vs 11.9%; p = 0.978) or total flap failures (9.3% vs 9.3%; p = 0.815) when controlling for the presence of arterial injury, flap type, and time from injury to coverage. Systematic review yielded 11 articles with 1,245 proximal and 127 distal anastomoses for comparison. Pooled analysis (p = 0.58) and weighted comparative analysis (p = 0.39) found no difference in flap failure rates between proximal and distal groups.
Conclusion Our results are congruent with the current lower extremity literature and demonstrate no difference in perioperative complication rates between anastomoses performed proximal or distal to the zone of injury. These findings suggest that anastomotic location choice should be based primarily on recipient vessel quality/flow and ease of access/exposure rather than orientation relative to the zone of injury.

Published: April 2018

AbstractRobotic surgery is gaining importance in complex thoracoscopic surgery, such as robotic-assisted minimally invasive esophagectomy (RAMIE). The RAMIE procedure was designed using the first generation of the robotic system. The latest da Vinci Xi system has substantially increased the dexterity, especially designed for multiquadrant surgery. The original three-arm RAMIE approach was modified including the robotic four-arm use for the thoracoscopic and laparoscopic part of the operation. This extended approach (four-arm RAMIE approach) provides more flexibility and raises the independence of the surgeon.

Abstract
Hirondellea species are common inhabitants in the hadal region deeper than 7,000 m. We found that Hirondellea gigas thrived in the Challenger Deep possessed polysaccharide hydrolases as digestive enzymes. To obtain various enzymes of other H. gigas, we captured amphipods from the Japan Trench, and Izu-Ogasawara (Bonin) Trench. A phylogenetic analysis based on the cytochrome oxidase I gene showed close relationships among amphipods, despite the geographic distance between the localities. However, several differences in enzymatic properties were observed in these H. gigas specimens. We also carried out RNA sequencing of H. gigas from the Izu-Ogasawara Trench. The cellulase gene of H. gigas was highly homologous to cellobiohydrolase of Glucosyl Hydrolase family 7 (GH7). On the other hand, enzymatic properties of H. gigas’s cellulase were different from those of typical GH7 cellobiohydrolase. Thus, these results indicate that hadal-zone amphipod can be good candidates as the new enzyme resource.

Published: April 2018

AbstractAn alkyd resin has been synthesized from palm oil that reacted with glycerol and phthalic anhydride by alcoholysis-polyesterification process and co-catalyzed by CuO nanoparticle. The CuO nanoparticle was pre-prepared in the glycerol via sol gel method, which creates a new reaction condition for resin preparation. The resins were characterized by fourier transform infrared spectroscopy (FTIR), where a new ester linkage bond (C-O-C) was noticed for resin sample. The antimicrobial activity and the curing behaviour of the resin were determined by Kirby-Bauer and differential scanning calorimeter technique. It was found that, the addition of CuO speeded up the reaction rate and played antimicrobial role. Moreover, it shortens the reaction time of alcoholysis and polyesterification process.
Civilizing the political society? Redevelopment regime and Urban Poor’s Rights in Mumbai
Authors: Jha Rishi 
Published: April 2018

Abstract
This article is concerned with informality-state relations, subaltern politics and citizenship in the context of the urban redevelopment regime. Based on an empirical study of an NGO (SPARC)-mediated resettlement of Project Affected Persons (PAPs) in Mumbai, it explicates the incomplete ‘civilizing of the political society’ which engenders asymmetrical material and leadership enablement and differential subjectivities at the community levels. The state co-opts SPARC’s institutional framework to mediate resettlement, engender limited traversal from ‘population’ to ‘citizen’, restrict democratic liberation and subject the PAPs to bifold governance against the antagonistic articulations of state-subaltern relations, viz. ‘political society’ and ‘deep democracy’. SPARC’s institutional claims of inclusion and community-centric resettlement, non-confrontational negotiations and politics of patience are materialized through institutional coercion, domesticated confrontations and inadequate compensation, and are augmented by the PAPs’ calculative rationalities, fear of homelessness and anticipation of urban citizenship. Against this backdrop and amid further post-resettlement marginalities that complicate housing-based ‘substantive citizenship’ and ‘political society’-based mediation, this article calls for a re-politicization of the redevelopment discourse to seek alternate possibilities of urban citizenship for the urban subaltern.
Tracking the NGS revolution: managing life science research on shared high-performance computing clusters
Authors: Dahlö Martin , Scofield Douglas G , Schaal Wesley , Spjuth Ola 
Published: April 2018

Abstract

Background
Next-generation sequencing (NGS) has transformed the life sciences, and many research groups are newly dependent upon computer clusters to store and analyze large datasets. This creates challenges for e-infrastructures accustomed to hosting computationally mature research in other sciences. Using data gathered from our own clusters at UPPMAX computing center at Uppsala University, Sweden, where core hour usage of ~800 NGS and ~200 non-NGS projects is now similar, we compare and contrast the growth, administrative burden, and cluster usage of NGS projects with projects from other sciences.

Results
The number of NGS projects has grown rapidly since 2010, with growth driven by entry of new research groups. Storage used by NGS projects has grown more rapidly since 2013 and is now limited by disk capacity. NGS users submit nearly twice as many support tickets per user, and 11 more tools are installed each month for NGS projects than for non-NGS projects. We developed usage and efficiency metrics and show that computing jobs for NGS projects use more RAM than non-NGS projects, are more variable in core usage, and rarely span multiple nodes. NGS jobs use booked resources less efficiently for a variety of reasons. Active monitoring can improve this somewhat.

Conclusions
Hosting NGS projects imposes a large administrative burden at UPPMAX due to large numbers of inexperienced users and diverse and rapidly evolving research areas. We provide a set of recommendations for e-infrastructures that host NGS research projects. We provide anonymized versions of our storage, job, and efficiency databases.

Published: April 2018

Abstract

BACKGROUND
Accurate cervical screw insertion is of paramount importance considering the risk of damage to adjacent vital structures. Recent research in 3-dimensional (3D) technology describes the advantage of patient-specific drill guides for accurate screw positioning, but consensus about the optimal guide design and the accuracy is lacking.

OBJECTIVE
To find the optimal design and to evaluate the accuracy of individualized 3D-printed drill guides for lateral mass and pedicle screw placement in the cervical and upper thoracic spine.

METHODS
Five Thiel-embalmed human cadavers were used for individualized drill-guide planning of 86 screw trajectories in the cervical and upper thoracic spine. Using 3D bone models reconstructed from acquired computed tomography scans, the drill guides were produced for both pedicle and lateral mass screw trajectories. During the study, the initial minimalistic design was refined, resulting in the advanced guide design. Screw trajectories were drilled and the realized trajectories were compared to the planned trajectories using 3D deviation analysis.

RESULTS
The overall entry point and 3D angular accuracy were 0.76 ± 0.52 mm and 3.22 ± 2.34°, respectively. Average measurements for the minimalistic guides were 1.20 mm for entry points, 5.61° for the 3D angulation, 2.38° for the 2D axial angulation, and 4.80° for the 2D sagittal angulation. For the advanced guides, the respective measurements were 0.66 mm, 2.72°, 1.26°, and 2.12°, respectively.

CONCLUSION
The study ultimately resulted in an advanced guide design including caudally positioned hooks, crosslink support structure, and metal inlays. The novel advanced drill guide design yields excellent drilling accuracy.
The Relationship Between Experiences of Lateral Violence and Career Choice Satisfaction Among Nursing Students
Authors: Furst Cari 
Published: April 2018

Abstract
This article explores associate degree nursing students’ experiences with lateral violence and its impact on career choice satisfaction. Lateral violence has been linked to decreased professional identity, increased errors, and poor self-esteem, leading to a negative culture and attrition. A nonexperimental, quantitative, cross-sectional, correlational design was used; 13.4 percent of respondents (n = 32) met the criteria for intermittent bullying. Analysis confirmed a significant negative correlation between experiences of lateral/vertical violence and career choice satisfaction (r = − .140, p < .05) even after controlling for affect and support. Improved efforts are needed to prevent lateral violence.
Is Short Same-Segment Fixation Really Better than Short-Segment Posterior Fixation in the Treatment of Thoracolumbar Fractures?
Authors: Ren Hai-long , Wang Ji-xing , Jiang Jian-ming 
Published: April 2018

Study Design.
A retrospective study.

Objective.
This retrospective study assessed whether short same-segment fixation (SSSF) is better than short-segment posterior fixation (SSPF) for reducing thoracolumbar fractures, improving the kyphosis angle, maintaining vertebral height, or reducing the incidence of broken screws.

Summary of Background Data.
In clinical practice, single-segment thoracolumbar fractures were then more likely to be treated with SSPF that included pedicle fixation at the level of the fracture (short same-segment fixation, or SSSF). Whether SSSF could really achieve vertebral height recovery, improve the kyphosis, reduce postoperative kyphosis loss, and reduce the incidence of internal fixation failure better than SSPF.

Methods.
Patients treated with SSPF or SSSF at our institution during 2006 to 2014 were reviewed. Effects of thoracolumbar fracture reduction, improved kyphosis angle, and maintaining vertebral height were compared between groups. Logistic regression analysis was used to identify factors related to instrumentation breakage and correlation analysis to assess possible relations between loss of correction of the kyphosis angle (LAWAC) and other factors.

Results.
Altogether, 130 patients were enrolled (53 SSPF, 77 SSSF). SSPF (22F, 31M) group's mean (range) age was 37.7 (16–60) years, and the follow-up was 26.2 (9–120) months. SSSF (27F, 50M) group's mean (range) age was 39.3 (17–61) years, and the follow-up was 23.2 (9–60) months. All patients underwent either internal fixation or screw repair. Immediately postoperatively, restoration after middle vertebral fractures was better in SSSF patients than in SSPF patients (P = 0.003), with no differences in other fracture-related factors (P > 0.05). Only LAWAC was significantly associated with instrumentation breakage (P < 0.05). Also, immediately postoperatively, the anterior/posterior vertebral heights ratio was negatively related to LAWAC.

Conclusion.
Pedicle fixation of the fracture did not obtain better recovery of anterior or posterior vertebral heights nor did it improve AWA restoration. There was no significant difference in LAWAC between groups or in the incidence of broken screws. LAWAC may increase the incidence of broken screws.
