Development and Validity of the Emotion and Motivation Self-Regulation Questionnaire (EMSR-Q)
Authors: Alonso-Tapia Jesús , Panadero Calderón Ernesto , Díaz Ruiz Miguel A. 
Published: July 2014

AbstractThis study has two objectives, first, to develop and validate the “Emotion and Motivation Self-regulation Questionnaire” (EMSR-Q), and second, to analyze (in the context of the questionnaire validation process) the relationships between self-regulation styles (SRS) rooted in goal orientations, and classroom motivational climate (CMC). A total of 664 Secondary Education students from Madrid (Spain) formed the sample of the study. It was divided randomly in two groups to perform confirmatory factor analysis and to cross-validate the results. Both analyses supported a five first-order factor structure, organized around two second-order factors, “Learning self-regulation style” (LSR) and “Avoidance self-regulation style” (ASR): (χ2/df = 2.71; GFI = .89; IFI = .84; CFI = .84; RMSEA = .07). Hypotheses concerning the relationships between SRS, goal orientations and expectancies are supported by additional correlation and factor analyses. Moreover, several regression analyses supported for the most part of the remaining hypotheses concerning the role of self-regulation styles as predictors of classroom motivational climate (CMC) perception, of change in self-regulation attributed to teacher work, and of students’ satisfaction with this same work. Theoretical and practical implications are discussed.
Managing Multiple Roles: Development of the Work-Family Conciliation Strategies Scale
Authors: Matias Marisa , Fontaine Anne Marie 
Published: July 2014

AbstractJuggling the demands of work and family is becoming increasingly difficult in today's world. As dual-earners are now a majority and men and women's roles in both the workplace and at home have changed, questions have been raised regarding how individuals and couples can balance family and work. Nevertheless, research addressing work-family conciliation strategies is limited to a conflict-driven approach and context-specific instruments are scarce. This study develops an instrument for assessing how dual-earners manage their multiple roles detaching from a conflict point of view highlighting the work-family conciliation strategies put forward by these couples. Through qualitative and quantitative procedures the Work-Family Conciliation Strategies Scales was developed and is composed by 5 factors: Couple Coping; Positive Attitude Towards Multiple Roles, Planning and Management Skills, Professional Adjustments and Institutional Support; with good adjustment [χ2/df = 1.22; CFI = .90, RMSEA = .04, SRMR = .08.] and good reliability coefficients [from .67 to .87]. The developed scale contributes to research because of its specificity to the work-family framework and its focus on the proactive nature of balancing work and family roles. The results support further use of this instrument.
Revealing the micromechanisms behind semi-solid metal deformation with time-resolved X-ray tomography

Published: July 2014

AbstractThe behaviour of granular solid–liquid mixtures is key when deforming a wide range of materials from cornstarch slurries to soils, rock and magma flows. Here we demonstrate that treating semi-solid alloys as a granular fluid is critical to understanding flow behaviour and defect formation during casting. Using synchrotron X-ray tomography, we directly measure the discrete grain response during uniaxial compression. We show that the stress–strain response at 64–93% solid is due to the shear-induced dilation of discrete rearranging grains. This leads to the counter-intuitive result that, in unfed samples, compression can open internal pores and draw the free surface into the liquid, resulting in cracking. A soil mechanics approach shows that, irrespective of initial solid fraction, the solid packing density moves towards a constant value during deformation, consistent with the existence of a critical state in mushy alloys analogous to soils.
Current Trends in Pediatric Cochlear Implant Candidate Selection and Postoperative Follow-Up
Authors: Uhler Kristin , Gifford René H. 
Published: July 2014

Purpose
In this article, the authors describe current pediatric cochlear implant (CI) assessment and postoperative scheduling protocols in the United States.

Method
A survey was conducted in 2 phases.

Results
Response rates were similar between Phase I (10%) and Phase II (13%). Across phases, nearly all respondents reported assessing speech perception both preoperatively and postoperatively. The most frequently used parent questionnaires were the Infant–Toddler Meaningful Auditory Integration Scale (Robbins, Renshaw, & Berry, 1991), the Meaningful Auditory Integration Scale (Robbins et al., 1991), and LittlEARS (Kuehn-Inacken, Weichboldt, Tsiakpini, Coninx, & D'Haese, 2003). The most commonly used speech perception measure for children <23 months of age was the Early Speech Perception Test–Low Verbal (ESP-LV; Moog & Geers, 1990). The most commonly used measures for children 24–35 months of age were the ESP-LV, the Northwestern University of Children's Perception of Speech (Elliot & Katz, 1980), and the Mr. Potato Head task (Robbins, 1993). For children >36 months of age, there was a wide variety of speech perception tests utilized. Patient follow-up visits were weekly or biweekly immediately following CI activation, then every 3 months for the remainder of the 1st year. After the 1st year, most children were seen semiannually.

Conclusions
Although trends emerged, there is a lack of consistency in the selection of speech perception measures utilized across centers for children <36 months of age. The development of a working group to establish a standard minimum pediatric test battery (similar to the adult Minimum Speech Test Battery) would promote uniformity in clinical protocols used to assess children who receive CIs.
Children's Understanding of Instructions Presented in Noise and Reverberation
Authors: Lewis Dawna E. , Manninen Crystal M. , Valente Daniel L. , Smith Nicholas A. 
Published: July 2014

Purpose
This study examined children's ability to follow audio–visual instructions presented in noise and reverberation.

Method
Children (8–12 years of age) with normal hearing followed instructions in noise or noise plus reverberation. Performance was compared for a single talker (ST), multiple talkers speaking one at a time (MT), and multiple talkers with competing comments from other talkers (MTC). Working memory was assessed using measures of digit span.

Results
Performance was better for children in noise than for those in noise plus reverberation. In noise, performance for ST was better than for either MT or MTC, and performance for MT was better than for MTC. In noise plus reverberation, performance for ST and MT was better than for MTC, but there were no differences between ST and MT. Digit span did not account for significant variance in the task.

Conclusions
Overall, children performed better in noise than in noise plus reverberation. However, differing patterns across conditions for the 2 environments suggested that the addition of reverberation may have affected performance in a way that was not apparent in noise alone. Continued research is needed to examine the differing effects of noise and reverberation on children's speech understanding.

The Rules of the Game: Properties of a Database of Expository Language Samples
Authors: Heilmann John , Malone Thomas O. 
Published: July 2014

Purpose
The authors created a database of expository oral language samples with the aims of describing the nature of students' expository discourse and providing benchmark data for typically developing preteen and teenage students.

Method
Using a favorite game or sport protocol, language samples were collected from 235 typically developing students in Grades 5, 6, 7, and 9. Twelve language measures were summarized from this database and analyses were completed to test for differences across ages and topics. To determine whether distinct dimensions of oral language could be captured with language measures from these expository samples, a factor analysis was completed.

Results
Modest differences were observed in language measures across ages and topics. The language measures were effectively classified into four distinct dimensions: syntactic complexity, expository content, discourse difficulties, and lexical diversity.

Conclusion
Analysis of expository data provides a functional and curriculum-based assessment that has the potential to allow clinicians to document multiple dimensions of children's expressive language skills. Further development and testing of the database will establish the feasibility of using it to compare individual students' expository discourse skills to those of their typically developing peers.
Encapsidated hepatitis B virus reverse transcriptase is poised on an ordered RNA lattice
Authors: Wang Joseph Che-Yen , Nickens David G. , Lentz Thomas B. , Loeb Daniel D. , Zlotnick Adam 
Published: July 2014

Significance
Hepatitis B virus (HBV) is a double-stranded DNA virus that packages a single-stranded RNA pregenome (pgRNA). The linear pgRNA is reverse transcribed to a gapped circular dsDNA within the confines of the virus capsid. We hypothesized that a specific capsid-RNA-reverse transcriptase structure would be required to accomplish this task. In this article, we report the structure of the authentic pgRNA-filled HBV core as determined by cryo-EM and asymmetric 3D reconstruction. The observed ordered structure suggests the assembly process and the first steps of reverse transcription follow a single, determinate pathway.
Nitrite formation from organic nitrogen by Streptomyces antibioticus supporting bacterial cell growth and possible involvement of nitric oxide as an intermediate
Authors: Sasaki Yasuyuki , Takaya Naoki , Morita Ayako , Nakamura Akira , Shoun Hirofumi 
Published: July 2014

Abstract
The actinomycete Streptomyces antibioticus was shown to produce nitrite and ammonium () when aerobically incubated in an organic nitrogen-rich medium. The production of was synchronized with rapid cell growth, whereas most was produced after cell proliferation had ceased. Intracellular formation of nitric oxide (NO) was also observed during the incubation. The production of these inorganic nitrogen compounds along with cell growth was prevented by several enzyme inhibitors (of nitric oxide synthase or nitrate reductase) or glucose. Distinct, membrane-bound nitrate reductase was induced in the -producing cells. Tungstate (a potent inhibitor of this enzyme) prevented the production and cell growth, whereas it did not prevent the NO formation. These results revealed the occurrence of novel nitrogen metabolic pathway in S. antibioticus forming from organic nitrogen by which rapid cell growth is possible. NO synthase, NO dioxygenase (flavohemoglobin), and dissimilatory nitrate reductase are possible enzymes responsible for the formation.

Authors: Randhawa Jaskirat S. , Budd George T. , Randhawa Mandeep , Ahluwalia Manmeet , Jia Xuefei , Daw Hamed , Spiro Timothy , Haddad Abdo 
Published: July 2014

Background:
Cardiac sarcomas are rare and have a poor prognosis. The median overall survival remains dismal and has been reported ranging from 6 months to a few years. Primary cardiac sarcoma is the most common malignant tumor comprising approximately 95% of all malignant tumors of the heart.

Methods:
We conducted a retrospective chart review in a single institution of patients diagnosed between March 1988 and April 2013. A total of 42 patients were identified. The following variables were studied: age at diagnosis, year of diagnosis, sex, stage, site of tumor involvement, tumor histology, grade, treatment modality, type of chemotherapy, and survival outcome. The overall median follow-up time was 49.5 months.

Results:
The most common histologic type was angiosarcoma. Overall estimated median survival (EMS) was 25 months. Tumors involving the left side of the heart and pericardium demonstrated better survival. Patients who received multimodality treatment (any combination of surgery, radiation therapy, and chemotherapy) had an EMS of 36.5 months compared with 14.1 months for patients treated with surgery, radiation therapy, or chemotherapy only (P=0.05).

Conclusions:
Cardiac sarcoma is a lethal tumor with an EMS of 25 months. The tumor histology could be a possible predictor of better survival. Although selection bias may have been present, multimodality therapy (surgery, radiation therapy, and chemotherapy) was associated with improved survival.
Function Preservation After Conservative Resection and Radiotherapy for Soft-tissue Sarcoma of the Distal Extremity
Authors: Cassidy Richard J. , Indelicato Daniel J. , Gibbs Charles P. , Scarborough Mark T. , Morris Christopher G. , Zlotecki Robert A. 
Published: July 2014

Objective:
To evaluate outcomes after conservative resection and radiotherapy (RT) for soft-tissue sarcoma (STS) of the distal extremity, with assessment of functional quality of life using the validated Toronto Extremity Salvage Score (TESS) questionnaire and Common Terminology Criteria for Adverse Events (CTCAE), v4.0.

Methods:
Thirty-three patients with STS involving the hand/wrist (N=18) or foot/ankle (N=15) complex received adjuvant RT with conservative resection and were evaluated for local tumor control, survival, toxicities, and preservation of objective functional ability. Eight patients were treated with preoperative RT (median dose, 50.4 Gy) and 25 with postoperative RT (median dose, 61.8 Gy). Median follow-up was 11.5 years. Functional outcomes were measured using TESS; patients with amputations were excluded from the TESS analysis. Adverse events related to gait, limb edema, skin infection, wound complication, and wound dehiscence were assessed using the CTCAE.

Results:
The 5- and 10-year local control rates were both 90%. The 10-year cause-specific, absolute, and distant metastasis-free survival rates were 97%, 87%, and 84%, respectively. Three patients had an amputation for reasons other than local recurrence or treatment complications and underwent amputation for patient preference. One third of the subjects (11/33 patients) were able to complete the TESS questionnaire; scores ranged from 88 to 100 (mean, 98.2). CTCAEv4 acute adverse events occurred in 2 cases: 1 patient had a grade 3 skin infection and 1 had a grade 2 wound complication of dehiscence.

Conclusions:
For management of distal extremity STS, the combination of adjuvant RT and conservative surgery achieves excellent local control and overall survival with few adverse events. In addition, through application of the TESS survey instrument, we have demonstrated that this treatment plan achieves robust functional preservation objectively and quantifiably.

Published: July 2014

Abstract
Understanding plant gene promoter architecture has long been a challenge due to the lack of relevant large-scale data sets and analysis methods. Here, we present a publicly available, large-scale transcription start site (TSS) data set in plants using a high-resolution method for analysis of 5′ ends of mRNA transcripts. Our data set is produced using the paired-end analysis of transcription start sites (PEAT) protocol, providing millions of TSS locations from wild-type Columbia-0 Arabidopsis thaliana whole root samples. Using this data set, we grouped TSS reads into “TSS tag clusters” and categorized clusters into three spatial initiation patterns: narrow peak, broad with peak, and weak peak. We then designed a machine learning model that predicts the presence of TSS tag clusters with outstanding sensitivity and specificity for all three initiation patterns. We used this model to analyze the transcription factor binding site content of promoters exhibiting these initiation patterns. In contrast to the canonical notions of TATA-containing and more broad “TATA-less” promoters, the model shows that, in plants, the vast majority of transcription start sites are TATA free and are defined by a large compendium of known DNA sequence binding elements. We present results on the usage of these elements and provide our Plant PEAT Peaks (3PEAT) model that predicts the presence of TSSs directly from sequence.
The Boron Efflux Transporter ROTTEN EAR Is Required for Maize Inflorescence Development and Fertility
Authors: Chatterjee Mithu , Tabi Zara , Galli Mary , Malcomber Simon , Buck Amy , Muszynski Michael , Gallavotti Andrea 
Published: July 2014

AbstractAlthough boron has a relatively low natural abundance, it is an essential plant micronutrient. Boron deficiencies cause major crop losses in several areas of the world, affecting reproduction and yield in diverse plant species. Despite the importance of boron in crop productivity, surprisingly little is known about its effects on developing reproductive organs. We isolated a maize (Zea mays) mutant, called rotten ear (rte), that shows distinct defects in vegetative and reproductive development, eventually causing widespread sterility in its inflorescences, the tassel and the ear. Positional cloning revealed that rte encodes a membrane-localized boron efflux transporter, co-orthologous to the Arabidopsis thaliana BOR1 protein. Depending on the availability of boron in the soil, rte plants show a wide range of phenotypic defects that can be fully rescued by supplementing the soil with exogenous boric acid, indicating that rte is crucial for boron transport into aerial tissues. rte is expressed in cells surrounding the xylem in both vegetative and reproductive tissues and is required for meristem activity and organ development. We show that low boron supply to the inflorescences results in widespread defects in cell and cell wall integrity, highlighting the structural importance of boron in the formation of fully fertile reproductive organs.

Purpose– The purpose of this paper is to examine the direct influence of three types of operations management practices, namely total quality management (TQM), lean manufacturing (LEAN), and supply chain management (SCM) on operational performance.Design/methodology/approach– Cluster analysis is used to classify data collected from Thai manufacturing firms into three business strategy clusters of cost leadership, differentiation, and focussed strategy. Next, multiple-regression analysis was used to test the relationships between operations management practices and performance in each of the three strategy clusters.Findings– Results show that all three operations management practices were significantly associated with performance including the interaction of TQM and SCM. Also, the interaction of LEAN and SCM significantly affected performance for firms pursuing focussed business strategy.Practical implications– Manufacturers in developing nations can use this result to deploy appropriate operations management practices to enhance their competitive edge.Originality/value– This study explores the cross-functional alignment between strategies and practices, which have been transferred from developed to developing countries.
Benchmarking suppliers’ performance when some factors play the role of both inputs and outputs
Authors: Mahdiloo Mahdi , Noorizadeh Abdollah , Farzipoor Saen Reza 
Published: July 2014

Purpose
– The purpose of this paper is to develop a slack-based measure (SBM) model in the presence of dual-role factor. Then it is applied in supplier selection problem.

Design/methodology/approach
– The developed model in this paper is based on data envelopment analysis (DEA) technique.

Findings
– The proposed evaluation platform is capable of identifying ill-performing suppliers which seek to future improvement. The findings provide valuable insights for practitioners, as well as academicians, policy makers and also integrate selection criteria under the supply chain.

Originality/value
– This is the first time that a non-radial DEA model considers dual-role factors. The proposed model does not deal with dual-role factor as a non-discretionary factor. The proposed model considers dual-role factors on both the input and output sides in a similar manner. The proposed model can fully measure the inefficiency of suppliers. The proposed model can give a complete ranking of suppliers.
