Effects of cell wall ultrastructure on the transverse shrinkage anisotropy of Scots pine wood
Authors: Bonarski Jan T. , Kifetew Girma , Olek Wiesław 
Published: October 2014

Abstract
A hypothesis for explaining the differential anisotropic shrinkage behavior of wood has been proposed, and it was based on the differences in the cell wall ultrastructure. The starting point of the consideration is that wood shrinkage is governed by its chemical composition, ultrastructure, and gross anatomy. It is also well known that the transverse shrinkage anisotropy of earlywood (EW) is more pronounced than that of the latewood (LW). In the paper, the cell wall ultrastructure and shrinkage anisotropy has been related to each other, and to this purpose, a set of crystallographic texture descriptors was applied. The descriptors are based on X-ray diffraction (XRD) experiments conducted on matched EW samples from different growth rings of Scots pine. The range of the microfibril angle (MFA) was identified. The ratio of the maxima of inverse pole figures (IPFs) of both the tangential (T) and radial (R) directions was determined. The ratios quantify the inhomogeneity of the spatial arrangement of the ordered areas. The results of the study clearly indicate that the transverse shrinkage of wood is governed mostly by a specific ultrastructural organization of moderately organized cell wall compounds.
Predicting the draft and career success of tight ends in the National Football League
Authors: Mulholland Jason , Jensen Shane T. 
Published: October 2014

AbstractNational Football League teams have complex drafting strategies based on college and combine performance that are intended to predict success in the NFL. In this paper, we focus on the tight end position, which is seeing growing importance as the NFL moves towards a more passing-oriented league. We create separate prediction models for 1. the NFL Draft and 2. NFL career performance based on data available prior to the NFL Draft: college performance, the NFL combine, and physical measures. We use linear regression and recursive partitioning decision trees to predict both NFL draft order and NFL career success based on this pre-draft data. With both modeling approaches, we find that the measures that are most predictive of NFL draft order are not necessarily the most predictive measures of NFL career success. This finding suggests that we can improve upon current drafting strategies for tight ends. After factoring the salary cost of drafted players into our analysis in order to predict tight ends with the highest value, we find that size measures (BMI, weight, height) are over-emphasized in the NFL draft.
Yucatecan-Mexican Relations and Yucatecan Politicking from 1829–1832: Centralism, Secession, and Federalism
Authors: Ali Shara 
Published: October 2014

This paper will explore Yucatecan-Mexican relations and local Yucatecan politicking during the early national period, using Yucatán’s pronunciamientos of 1829 to 1832 as case studies. This examination will highlight that, while Yucatán has historically been perceived as a marginal and pro-autonomous state of early nineteenth-century Mexico, in fact, the years of Yucatecan secession from 1829–1832 were instigated by a small but powerful government, and the majority of Yucatecan economic, military and political factions still desired unification with and possessed loyalty to Mexico. In turn, this examination will contribute to re-defining the identification of Yucatán as a secessionist state.
Este artículo explora las relaciones México-Yucatán y la forma yucateca de hacer política durante los primeros años del periodo nacional, tomando como caso los pronunciamientos de 1829 y 1832. Nuestro examen subrayará que, aun cuando Yucatán haya sido percibido históricamente como un estado marginal y pro-autónomo de principios del siglo xix en México, los años de secesión yucateca, entre 1829 y 1832, realmente fueron instigados por un gobierno pequeño pero poderoso, y la mayoría de las facciones económicas, militares y políticas yucatecas aún deseaban la unificación y eran leales a México. A su vez, este examen contribuirá a redefinir la identificación de Yucatán como un estado secesionista.
Chucho el Roto in Mexico’s Post-1968 Cinema: Banditry, State-Sponsored Violence, and the Alternative National Family
Authors: Robinson Amy 
Published: October 2014

Legendary bandit Chucho el Roto was portrayed by renowned actor Manuel López Ochoa in a film series made and released in the wake of violent repression of Mexico’s student movement. The four films provide entertainment with their charismatic leading man, melodrama, romance and comedy. Yet, the series also allegorizes and critiques Dirty War tactics employed in Mexico by portraying how the powerful abuse their authority to criminalize, imprison, torture and murder young idealists with an alternative vision for society. The popular figure of the bandit thus constituted a timely vehicle for critical reflection about political violence within a repressive climate.Chucho el Roto, el bandido legendario, fue retratado por el afamado actor Manuel López Ochoa en una serie de películas filmadas y estrenadas tras la violenta represión del movimiento estudiantil mexicano. Las cuatro películas proporcionan entretenimiento gracias a su carismático protagonista, al melodrama, el romance y la comedia. Sin embargo la serie también alegoriza y critica las tácticas de la Guerra Sucia empleadas en México, y lo hace mediante un retrato del poderoso abuso de sus autoridades para criminalizar, apresar, torturar y asesinar a jóvenes idealistas con una visión alternativa para la sociedad. La figura popular del bandido constituyó así un vehículo oportuno para la reflexión crítica sobre la violencia política dentro de un clima represivo.
The Role of Financial Derivative Instruments in the Emerging Market Financial Crises of the Late 1990s: The Mexican Case
Authors: Hayali Ayca Sarialioglu 
Published: October 2014

Although derivatives were developed for the treatment of some diseases, such as risks and volatilities, ironically, as experienced in the 1990s, they, themselves, created them as sometimes “adverse effects” of hedging or with deliberately harmful purposes of speculation. This paper aims to analyze the role of financial derivatives in the emerging markets financial crises of the 1990s. In this regard, it deals with the Mexican case through a VAR-GARCH approach. The paper found that financial derivatives had an increasing impact on the currency crises of Mexico. This was an immediate destabilizing effect on the volatility of the spot exchange rates.
Si bien los derivados fueron desarrollados para tratar ciertas enfermedades como los riesgos y la volatilidad, irónicamente, como se vivió en la década de 1990, ellos mismos crearon en ocasiones esos problemas como “efectos secundarios” de la cobertura, o bien, con intenciones deliberadamente dañinas de especulación. Este artículo busca analizar el rol de los derivados financieros en las crisis de los noventa dentro de los mercados emergentes. Así pues, se trata el caso mexicano mediante un enfoque VaR-GARCH. El artículo encuentra que los derivados financieros tuvieron un impacto creciente en las crisis monetarias de México. Éste fue un efecto desestabilizador inmediato sobre la volatilidad de las tasas de cambio al contado.

Passivation and Annealing for Improved Stability of High Performance IGZO TFTs
Authors: Mudgal T. , Walsh N. , Manley R.G. , Hirschman K.D. 
Published: October 2014

ABSTRACTThe influence of annealing ambient conditions and deposited passivation materials on indium-gallium-zinc-oxide (IGZO) thin-film transistor (TFT) performance is investigated. Results from annealing experiments confirm that a nominal exposure to oxidizing ambient conditions is required, which is a function of temperature, time and gas environment. Nitrogen anneal with a controlled air ramp-down provided the best performance devices with a mobility (µsat) of 11-13 cm2/V·s and subthreshold slope (SS) of 135-200 mV/dec, with some hysteresis. Plasma-deposited passivation materials including sputtered quartz and PECVD SiO2 demonstrated a significant increase in material conductivity, which was not significantly reversible by an oxidizing ambient anneal. E-beam evaporated Al2O3 passivated devices that were annealed in air at 400 °C demonstrated improved stability over time and suppressed hysteresis in comparison to unpassivated devices. Devices which were passivated with B-staged bisbenzocyclobutene-based (BCB) resins and annealed in air at 250 °C also exhibited suppressed hysteresis.
Quantum chemistry computations of properties of acrylamide dimers
Authors: Wang Yi-Siang , Lin Yi-De , Chao Sheng D. 
Published: October 2014

ABSTRACTIntermolecular interaction potentials of the acrylamide dimer in 12 equilibrium configurations have been calculated using the second-order Møller-Plesset (MP2) perturbation theory. We have employed Pople’s medium size basis sets [up to 6-311++G(3df,2p)] and Dunning’s correlation consistent basis sets (up to aug-cc-pVTZ). We have also carried out density functional theory (DFT) type calculations and compared the results with those calculated with the MP2 theory.
Materials Science Research to Open Doors for Economically Disadvantaged High School Students: The ACS Project SEED Program at Clark Atlanta University

Published: October 2014

ABSTRACTThe Center for Functional Nanoscale Materials (CFNM), an NSF Center for Research Excellence in Science and Technology, at Clark Atlanta University has partnered with ACS (American Chemical Society) Project SEED. The ACS project SEED program is recognized nationally as providing hands-on research opportunities to disadvantaged high school students who historically lack exposures to scientific careers. The University is a minority serving institution (MSI) and has an excellent relationship with Atlanta area school systems, which serve the African American community. Students entering their junior and senior years in high school were selected based on their academic performance, an essay and letters of recommendation for participation the Center’s eight week summer nanoscholar Program. Professors served as advisors and/or mentors and graduate students and doctoral fellows served as mentors. The Program included a variety of enrichment activities. All summer nanoscholars had personal research projects that were integral to the research programs of their advisors, and they presented their work in the form of a symposium at the end of the Program. We have completed three summers as an ACS Project SEED site. So far we have had one SEED scholar submit a major manuscript, two were invited to present at ACS National Meetings and one was awarded an eight year Gates-Millennium fellowship. Evaluation of the project strongly suggests that our approach is effective for opening doors for the economically disadvantaged students and tapping the best and the brightest for careers in the sciences and engineering. In the words of one of our young scholars “I realized that research is a continuous learning process. You can never know everything. Even a professor has credentials but they’re still continuing to learn.”

Published: October 2014

Background: Management of gingival recession defects, a common periodontal condition, using root coverage procedures is an important aspect of periodontal regenerative therapy. The goal of the periodontal soft tissue root coverage procedures group was to develop a consensus report based on the accompanying systematic review of root coverage procedures, including priorities for future research and identification of the best evidence available to manage different clinical scenarios.Methods: The group reviewed and discussed the accompanying systematic review, which covered treatment of single‐tooth recession defects, multiple‐tooth recession defects, and additional focused questions on relevant clinical topics. The consensus group members submitted additional material for consideration by the group in advance and at the time of the meeting. The group also identified priorities for future research.Results: All reviewed root coverage procedures provide significant reduction in recession depth, especially for Miller Class I and II recession defects. Subepithelial connective tissue graft (SCTG) procedures provide the best root coverage outcomes. Acellular dermal matrix graft (ADMG) or enamel matrix derivative (EMD) in conjunction with a coronally advanced flap (CAF) can serve as alternatives to autogenous donor tissue. Additional research is needed to do the following: 1) assess the treatment outcomes for multiple‐tooth recession defects, oral sites other than maxillary canine and premolar teeth, and Miller Class III and IV defects; 2) assess the role of patient‐ and site‐specific factors on procedure outcomes; and 3) obtain evidence on patient‐reported outcomes.Conclusions: Predictable root coverage is possible for single‐tooth and multiple‐tooth recession defects, with SCTG procedures providing the best root coverage outcomes. Alternatives to SCTG are supported by evidence of varying strength. Additional research is needed on treatment outcomes for specific oral sites.Clinical Recommendation: For Miller Class I and II single‐tooth recession defects, SCTG procedures provide the best outcomes, whereas ADMG or EMD in conjunction with CAF may be used as an alternative.

OBJECTIVE
Obesity and type 2 diabetes mellitus (T2DM) have been associated with increased levels of circulating branched-chain amino acids (BCAAs) that may be involved in the pathogenesis of insulin resistance. However, weight loss has not been consistently associated with the reduction of BCAA levels.

RESEARCH DESIGN AND METHODS
We included 30 obese normal glucose-tolerant (NGT) subjects, 32 obese subjects with T2DM, and 12 lean female subjects. Obese subjects underwent either a restrictive procedure (gastric banding [GB], a very low-calorie diet [VLCD]), or a restrictive/bypass procedure (Roux-en-Y gastric bypass [RYGB] surgery). Fasting blood samples were taken for the determination of amine group containing metabolites 4 weeks before, as well as 3 weeks and 3 months after the intervention.

RESULTS
BCAA levels were higher in T2DM subjects, but not in NGT subjects, compared with lean subjects. Principal component (PC) analysis revealed a concise PC consisting of all BCAAs, which showed a correlation with measures of insulin sensitivity and glucose tolerance. Only after the RYGB procedure, and at both 3 weeks and 3 months, were circulating BCAA levels reduced.

CONCLUSIONS
Our data confirm an association between deregulation of BCAA metabolism in plasma and insulin resistance and glucose intolerance. Three weeks after undergoing RYGB surgery, a significant decrease in BCAAs in both NGT as well as T2DM subjects was observed. After 3 months, despite inducing significant weight loss, neither GB nor VLCD induced a reduction in BCAA levels. Our results indicate that the bypass procedure of RYGB surgery, independent of weight loss or the presence of T2DM, reduces BCAA levels in obese subjects.

Published: October 2014

OBJECTIVE
Medication nonadherence is a major obstacle to better control of glucose, blood pressure (BP), and LDL cholesterol in adults with diabetes. Inexpensive effective strategies to increase medication adherence are needed.

RESEARCH DESIGN AND METHODS
In a pragmatic randomized trial, we randomly assigned 2,378 adults with diabetes mellitus who had recently been prescribed a new class of medication for treating elevated levels of glycated hemoglobin (A1C) ≥8% (64 mmol/mol), BP ≥140/90 mmHg, or LDL cholesterol ≥100 mg/dL, to receive 1) one scripted telephone call from a diabetes educator or clinical pharmacist to identify and address nonadherence to the new medication or 2) usual care. Hierarchical linear and logistic regression models were used to assess the impact on 1) the first medication fill within 60 days of the prescription; 2) two or more medication fills within 180 days of the prescription; and 3) clinically significant improvement in levels of A1C, BP, or LDL cholesterol.

RESULTS
Of the 2,378 subjects, 89.3% in the intervention group and 87.4% in the usual-care group had sufficient data to analyze study outcomes. In intent-to-treat analyses, intervention was not associated with significant improvement in primary adherence, medication persistence, or intermediate outcomes of care. Results were similar across subgroups of patients defined by age, sex, race/ethnicity, and study site, and when limiting the analysis to those who completed the intended intervention.

CONCLUSIONS
This low-intensity intervention did not significantly improve medication adherence or control of glucose, BP, or LDL cholesterol. Wide use of this strategy does not appear to be warranted; alternative approaches to identify and improve medication adherence and persistence are needed.

OBJECTIVE
Depressive symptoms are common and, when coexisting with diabetes, worsen outcomes and increase health care costs. We evaluated a nurse case-manager–based collaborative primary care team model to improve depressive symptoms in diabetic patients.

RESEARCH DESIGN AND METHODS
We conducted a controlled implementation trial in four nonmetropolitan primary care networks. Eligible patients had type 2 diabetes and screened positive for depressive symptoms, based on a Patient Health Questionnaire (PHQ) score of ≥10. Patients were allocated using an “on-off” monthly time series. Intervention consisted of case-managers working 1:1 with patients to deliver individualized care. The main outcome was improvement in PHQ scores at 12 months. A concurrent cohort of 71 comparable patients was used as nonscreened usual care control subjects.

RESULTS
Of 1,924 patients screened, 476 (25%) had a PHQ score &gt;10. Of these, 95 were allocated to intervention and 62 to active control. There were no baseline differences between groups: mean age was 57.8 years, 55% were women, and the mean PHQ score was 14.5 (SD 3.7). Intervention patients had greater 12-month improvements in PHQ (7.3 [SD 5.6]) compared with active-control subjects (5.2 [SD 5.7], P = 0.015). Recovery of depressive symptoms (i.e., PHQ reduced by 50%) was greater among intervention patients (61% vs. 44%, P = 0.03). Compared with trial patients, nonscreened control subjects had significantly less improvement at 12 months in the PHQ score (3.2 [SD 4.9]) and lower rates of recovery (24%, P &lt; 0.05 for both).

CONCLUSIONS
In patients with type 2 diabetes who screened positive for depressive symptoms, collaborative care improved depressive symptoms, but physician notification and follow-up was also a clinically effective initial strategy compared with usual care.
Basic Comparison of the Properties of the Loop and Frotte Yarns, Woven and Knitted Fabrics
Authors: Ewa Grabowska Katarzyna , Ciesielska-Wróbel Izabela 
Published: October 2014

Abstract
Both loop fancy yarns and frotte fancy yarns belong to the group of yarns with continuous effects. The difference between frotte and loop yarn relies on the fact that the loop yarn is constructed with two core yarns and the frotte yarn is constructed with only one core yarn. The differences are evident in the shape of these two types of fancy yarns. These shape differences are the functions of the tensions of component yarns during the twisting process. The shape and construction of the fancy yarn influence its properties. The properties of loop and frotte fancy yarns, woven and knitted fabrics are compared in this article in order to find out the optimal yarn’s and fabric’s production condition to satisfy the final user and maintain low production costs. In terms of economy aspects only, the frotte fancy yarns are believed to be cheaper in production due to lower quantity of components utilize for their production to compare with loop fancy yarns, under conditions of the same settings of ring twisting frame.
Drop Impact on Textile Material: Effect of Fabric Properties

Published: October 2014

Abstract
This paper presents an experimental study of impact of water drop on a surface in a spreading regime with no splashing. Three surfaces were studied: virgin glass, coating film and woven cotton fabric at different construction parameters. All experiments were carried out using water drop with the same free fall high. Digidrop with high-resolution camera is used to measure the different parameters characterising this phenomenon. Results show an important effect of the height of the free fall on the drop profile and the spreading behaviour. An important drop deformation at the surface impact was observed. Then, fabric construction as the weft count deeply affects the drop impact. For plain weave, an increase of weft count causes a decrease in penetration and increase in the spreading rate. The same result was obtained for coated fabric. Therefore, the impact energy was modified and the drop shape was affected, which directly influenced the spreading rate.
