“Broken windows”: Relationship between neighborhood conditions and behavioral health among low-income African American adolescents
Authors: Voisin Dexter R , Kim Dong Ha
Published: August 2017

This study explored the association between neighborhood conditions and behavioral health among African American youth. Cross-sectional data were collected from 683 African American youth from low-income communities. Measures for demographics, neighborhood conditions (i.e. broken windows index), mental health, delinquency, substance use, and sexual risk behaviors were assessed. Major findings indicated that participants who reported poorer neighborhood conditions compared to those who lived in better living conditions were more likely to report higher rates of mental health problems, delinquency, substance use, and unsafe sexual behaviors. Environmental factors need to be considered when addressing the behavioral health of low-income African American youth.
Culturally based health assumptions in Sub-Saharan African immigrants: Body mass index predicting self-reported health status
Authors: Ngoubene-Atioky Arlette J , Williamson-Taylor Claudette
Published: August 2017

This study examined whether Sub-Saharan African adult immigrants maintained cultural preferences for curvier/higher body size post-migration to the United States. Linear and multiple regression analyses were utilized to discern the predicting effects of Sub-Saharan African immigrants’ body mass index score on their self-reported health status at two post-migration data collection points. The initial assessment reveals that Sub-Saharan African immigrants’ overweight body mass index score predicted better self-reported health status. Four to six years later, higher body mass index score predicted a better self-reported health status and lower dietary acculturation moderated the predicting effect of body mass index on self-reported health status. Limitations of the study and implications for research and practice are explored.
Biodynamics of supine humans and interaction with transport systems during vibration and shocks
Authors: Rahmatalla Salam , DeShaw Jonathan , Barazanji Khalid
Published: August 2017

This work investigates the effect of the contact surfaces on the biomechanical response of supine humans during whole-body vibration and shocks. Twelve participants were exposed to three-dimensional random vibration and shocks and were tested with two types of contact surfaces: (i) litter only, and (ii) litter with spinal board. The two configurations were tested with and without body straps to secure the supine human. The addition of the spinal board reduced the involuntary motion of the supine humans in most directions. There were significant reductions in the relative vertical accelerations at the neck and torso areas, especially during shocks ( p < 0.01). The inclusion of body straps with the spinal board was more effective in reducing the relative motion in most directions when shocks were presented. This study shows that the ergonomic design of the human transport system and the underlying contacting surfaces should be studied during dynamic transport environments.
Mahalanobis distance among the phase portraits as damage feature
Authors: George Riya C , Mishra Sudib K , Dwivedi Mohit
Published: August 2017

A number of damage-sensitive features have been proposed based on the damage-induced changes in the phase portrait, reconstructed from the measured dynamic responses of structure. Of a number of alternatives, the change in phase space topology is the most widely acclaimed for assessment of structural health. In this study, a damage feature is proposed by contrasting the damaged phase portrait with the pristine one. The contrast is expressed using the Mahalanobis distance measure, which is remarkably simpler than the change in phase space topology in algorithmic aspect. The feature is referred as Mahalanobis distance among the phase portraits. The performance of the feature is demonstrated by its sensitivity and localization of damage. The noise immunity study reveals reasonable tolerance to the measurement noise. The feature is numerically illustrated on a shear building subjected to Lorentz chaotic excitations and natural wind excitations. The feature is experimentally verified in a railway bridge model subjected to moving wheel load of a model train. The results show the effectiveness of the feature for localizing both the support damage (as in bearing) and damage in the span. Simple analytical argument is also provided to link the phase portrait distortion with the extent and localization of damage(s).
An energy-balance and game-theory-based cluster formation method for wireless sensor networks
Authors: Wu Xuegang , Zeng Xiaoping , Fang Bin , Yang Liu , Zhang Wei
Published: August 2017

Clustering techniques in wireless sensor networks have been widely utilized for their good performance in reducing energy dissipation and prolonging network lifetime. Once the cluster heads have been decided, the allocation of member nodes in the cross coverages formed by two or more clusters is critical to keep an energy balance on the cluster heads. In earlier studies, however, the allocation of member nodes simply depends on the distance or degree (the node number within the cluster heads’ communication radius) and, therefore, could cause imbalance to the cluster heads’ load and further degrade the whole wireless sensor network. To maintain the load balance of the cluster heads, in this article, game theory is introduced into the allocation problem of the member nodes. Before using the game theory approach, the number and distribution of cluster heads are first checked. If the cover rate of the cluster heads is low, then the node(s) uncovered by any cluster are randomly selected as new cluster head(s) to attain the cover rate required in the article. Furthermore, the number of cluster heads in a monitoring region is restricted. Finally, a game-based, energy-balance method is proposed and applied in the cluster-based routing protocols to improve their performance. For verification, the proposed method is embedded into the localized game theoretical clustering algorithm and hybrid, game theory–based and distributed clustering algorithm, which are two game theory and typical cluster-based routing protocols. The experimental results show that both of the improved protocols do balance the loads of the cluster heads and achieve better performance than their original versions in spanning the lifetime and balancing the energy in wireless sensor networks.
RMDS: Ranging and multidimensional scaling–based anchor-free localization in large-scale wireless sensor networks with coverage holes
Authors: Li Qiyue , Chu Baoyu , Wu Zhong , Sun Wei , Chen Liangfeng , Li Jie , Liu Zhi
Published: August 2017

Sensor node localization is a crucial aspect of many location-related applications that utilize wireless sensor networks. Among the many studies in the literature, multidimensional scaling-based localization techniques have been proven to be efficient, obtaining high accuracy with lower information requirements. However, when applied to large-scale wireless sensor networks with coverage holes, which are common in many scenarios, such as underground mines, the transmission path can become deviated, degrading the localization performance of this type of connectivity-based technique. Furthermore, in such complex wireless environments, non-line-of-sight reference objects, the presence of obstacles and signal fluctuations change the communication range and make it difficult to obtain an accurate position. In this article, we present a anchor-free localization scheme for large-scale wireless sensor networks called the ranging and multidimensional scaling–based localization scheme. We use ranging and non-line-of-sight error mitigation techniques to estimate accurate distances between each node pair and attempt to find inflection nodes using a novel flooding protocol to correct transmission paths that have become deviated by a coverage hole. Moreover, we replace the singular value decomposition with an iterative maximum gradient descent method to reduce the computational complexity. The results of the simulations and experiments show that our scheme performs well on wireless sensor networks with different coverage holes and is robust to varying network densities.

Authors: Sanders Thomas L. , Pareek Ayoosh , Hewett Timothy E. , Stuart Michael J. , Dahm Diane L. , Krych Aaron J.
Published: August 2017

Background:

First-time lateral patellar dislocation is a common orthopaedic injury. The purposes of this study were to (1) evaluate the incidence of first-time lateral patellar dislocation in a geographically-determined population, (2) report trends over time in the incidence of dislocation, and (3) describe the rate of surgical treatment.

Hypothesis:

The rate of patellar dislocation is highest among adolescent patients.

Study Design:

Cohort study.

Level of Evidence:

Level 3.

Methods:

The study population included 609 individuals identified through a multidisciplinary geographic cohort county database who were diagnosed with first-episode lateral patellar dislocation between 1990 and 2010. The complete medical records were reviewed to confirm the diagnosis and to evaluate details of injury and treatment. Age- and sex-specific incidence rates were calculated and adjusted to the 2010 US population. Poisson regression analyses were performed to examine incidence trends by age, sex, and calendar period.

Results:

The overall age- and sex-adjusted annual incidence of patellar dislocation was 23.2 (95% CI, 21.2-24.9) per 100,000 person-years. The annual incidence was similar between male and female patients and highest among adolescents aged 14 to 18 years (147.7/100,000 person-years). The mean age at dislocation was 21.4 ± 9.9 years, and 331 patients (54.4%) were female. During the study period, there was a significant decline in the incidence of patellar dislocation among men aged 19 to 25 years ( P = 0.002) and girls aged 14 to 18 years ( P = 0.025). Eighty patients received surgical treatment during the study period, including 66 patients (10.8%) for recurrent instability and 14 patients (2.3%) for acute osteochondral injury.

Conclusion:

With an annual incidence of 23.2 per 100,000 person-years, lateral patellar dislocation is a frequently encountered orthopaedic injury. The incidence of dislocation among adolescent patients in this cohort is higher than previously reported. Despite a decrease in the annual incidence of dislocation in adolescent girls, the overall incidence of patellar dislocation remained relatively constant over a 21-year observation period.

Clinical Relevance:

This study demonstrates that the incidence of patellar dislocation in adolescents is greater than previously reported.
Effects of combined treatment with fermented soybean (natto) intake and exercise on bone metabolism in ovariectomized rats
Authors: Kawano Michihiro , Itomine Ichiro , Monma Masahiko , Asakawa Kazumi , Toyoda Atsushi , Miyaguchi Yuji
Published: August 2017

Objectives:

Using ovariectomized rats, we examined the influence of combined exercise tolerance and natto intake on the bone loss inhibitory effect.

Methods:

We divided female Wistar rats into the following groups: Ovariectomy, Ovariectomy + Exercise, Ovariectomy + Natto Intake, Ovariectomy + Exercise + Natto Intake, and Pseudo-operative (Sham group). After conducting experiments on each group, we collected the tissues and performed morphological and molecular biological analyses.

Results:

In comparison with the Ovariectomy group, only in the Ovariectomy + Exercise group was there a significant bone loss inhibitory effect in the femoral cancellous bone. Although there was a tendency toward this trend seen in the Natto Intake and Exercise + Natto Intake groups, these differences were not significant. The increase in messenger RNA expression levels of alkaline phosphatase (osteoblast marker) in the bone marrow caused by ovariectomy was suppressed by individual factors, and by those in combination. However, messenger RNA expression levels of estrogen receptor alpha in the bone marrow showed a decreasing tendency with each factor, and decreased significantly with the combination, similar to the Sham group.

Conclusion:

This suggests that natto intake and exercise maintain bone mass by different molecular mechanisms and that these two factors do not simply act synergistically in combination to maintain bone mass.
Humeral Avulsion of the Glenohumeral Ligament: Indications for Surgical Treatment and Outcomes—A Systematic Review
Authors: Bozzo Anthony , Oitment Colby , Thornley Patrick , Yan James , Habib Anthony , Hoppe Daniel J. , Athwal George S. , Ayeni Olufemi R.
Published: August 2017

Background:

The inferior glenohumeral ligament, the most important static anterior stabilizer of the shoulder, becomes disrupted in humeral avulsion of the glenohumeral ligament (HAGL) lesions. Unfortunately, HAGL lesions commonly go unrecognized. A missed HAGL during an index operation to treat anterior shoulder instability may lead to persistent instability. Currently, there are no large studies describing the indications for surgical repair or the outcomes of patients with HAGL lesions.

Purpose:

To search the literature to identify surgical indications for the treatment of HAGL lesions and discuss reported outcomes.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

Two reviewers completed a comprehensive literature search of 3 online databases (MEDLINE, EMBASE, and Cochrane Library) from inception until May 25, 2016, using the keywords “humeral avulsion of the glenohumeral ligament” or “HAGL” to generate a broad search. Systematic screening of eligible studies was undertaken in duplicate. Abstracted data were organized in table format, with descriptive statistics presented.

Results:

After screening, 18 studies comprising 118 patients were found that described surgical intervention and outcomes for HAGL lesions. The mean patient was 22 years (range, 12-50 years), and 82% were male. Sports injuries represented 72% of all HAGL injuries. The main surgical indication was primary anterior instability, followed by pain and failed nonoperative management. Commonly associated injuries in patients with identified HAGL lesions included a Bankart lesion (15%), Hill-Sachs lesions (13%), and glenoid bone loss (7%). Reporting of outcome scores varied among the included studies. Meta-analysis was not possible, but all included studies reported significantly improved postoperative stability and function. There were no demonstrated differences in outcomes for patients treated with open versus arthroscopic surgical techniques. All but 2 patients undergoing operative management for HAGL lesions were able to return to sport at their previous levels; these included Olympians and professional athletes.

Conclusion:

HAGL lesions typically occur in younger male patients and are often associated with Bankart lesions and bone loss. Open and arthroscopic management techniques are both effective in preventing recurrent instability.

Published: August 2017

Background

Emergence of artemisinin-resistant malaria in Southeast Asian countries threatens the global control of malaria. Although K13 kelch propeller has been assessed for artemisinin resistance molecular marker, most of the mutations need to be validated. In this study, artemisinin resistance was assessed by clinical and molecular analysis, including k13 and recently reported markers, pfarps10, pffd and pfmdr2.

Methods

A prospective cohort study in 1160 uncomplicated falciparum patients was conducted after treatment with artemisinin-based combination therapy (ACT), in 6 sentinel sites in Myanmar from 2009 to 2013. Therapeutic efficacy of ACT was assessed by longitudinal follow ups. Molecular markers analysis was done on all available day 0 samples.

Results

True recrudescence treatment failures cases and day 3 parasite positivity were detected at only the southern Myanmar sites. Day 3 positive and k13 mutants with higher prevalence of underlying genetic foci predisposing to become k13 mutant were detected only in southern Myanmar since 2009 and comparatively fewer mutations of pfarps10, pffd, and pfmdr2 were observed in western Myanmar. K13 mutations, V127M of pfarps10, D193Y of pffd, and T448I of pfmdr2 were significantly associated with day 3 positivity (OR: 6.48, 3.88, 2.88, and 2.52, respectively).

Conclusions

Apart from k13, pfarps10, pffd and pfmdr2 are also useful for molecular surveillance of artemisinin resistance especially where k13 mutation has not been reported. Appropriate action to eliminate the resistant parasites and surveillance on artemisinin resistance should be strengthened in Myanmar.

Trial registration This study was registered with ClinicalTrials.gov, identifier NCT02792816.

Published: August 2017

This article discusses the technical examination of five flower and fruit still life paintings by the seventeenth century artist Jan Davidsz. de Heem (1606–1684). The painter is known for his meticulously composed and finely detailed still life paintings and is a master in imitating the surface textures of various fruits, flowers, and objects. Macro X-ray fluorescence (MA-XRF) scanning experiments were supplemented with a study of paint cross-sections and contemporary art technical sources with the aim of reconstructing the complex build-up of the overall lay-in of the composition and individual subjects. MA-XRF provided information on the distribution of key chemical elements present in painting materials and made it possible to recapture evidence of the different phases in the artist’s working methods: from the application of the ground layers, to De Heem’s characteristic oval-shaped underpaintings, and finally, the superposition of multiple paint layers in the working up of the paintings. SEM–EDX analysis of a limited number of paint cross-sections complemented the chemical images with local and layer-specific information on the microscale, providing more accuracy on the layer sequence and enabling the study of elements with a low atomic number for which the non-invasive technique is less sensitive. The results from this technical examination were in addition compared with recipes and paint instructions, to obtain a better understanding of the relation between the general practice and actual painting technique of Jan Davidsz. de Heem. Ultimately, this combined approach uncovered new information on De Heem’s artistic practice and demonstrated the complementarity of the methods.

Published: August 2017

Purpose:

Early palliative care (PC) improves outcomes for outpatients with advanced cancer. Its effect on hospitalized patients with cancer is unknown. Herein, we report on the influence of a novel, fully integrated inpatient medical oncology and PC partnership at a tertiary medical center during its first year of implementation.

Methods:

We conducted a retrospective, longitudinal, pre- and postintervention cohort study at Duke University Hospital. Pre- and postintervention cohorts were defined as all patients admitted to the solid tumor inpatient service from September 1, 2009, to June 30, 2010, and September 1, 2011 to June 30, 2012, respectively. We extracted patient data, including demographics, cancer diagnosis, disease status, length of stay, intensive care unit transfer rate, discharge disposition, time to emergency department return, time to readmission, and 7- and 30-day emergency department return and readmission rates. Nursing and physician surveys assessed satisfaction. Descriptive statistics, and Kruskal-Wallis and Χ2 tests were used to describe and compare cohorts. A generalized estimating equation accounted for repeated measures.

Results:

Pre- and postintervention analysis cohorts included 731 and 783 patients, respectively, representing a total of 1,514 patients and 2,353 encounters. Cohorts were similar in baseline characteristics. Statistically significant lower odds in 7-day readmission rates were observed in the postintervention cohort (adjusted odds ratio, 0.76; 95% CI, 0.58 to 1.00; P = .0482). Patients in the postintervention group had a decrease in mean length of stay (−0.30 days; 95% CI, −0.62 to 0.02); P = .0651). We observed a trend for increasing hospice referrals ( P = .0837) and a 15% decrease in intensive care unit transfers ( P = .61). Physicians and nurses universally favored the model.

Conclusion:

A fully integrated inpatient partnership between PC and medical oncology is associated with significant and clinically meaningful improvements in key health system–related outcomes and indicators of quality cancer care.

Published: August 2017

Background: Breast cancer (BC) remains one of the leading causes of death in women worldwide. The BRCA1 deleterious mutation has a significant role in developing BC, and the risk has been estimated to be 46–87%. Many studies emphasize the need for mining BRCA1 gene mutations that might have a role in BC pathogenesis and could affect early disease onset. This study was conducted to screen for possible pathogenic single nucleotide polymorphisms (SNPs) in BRCA1, targeting three regions: two in exon 11 and the third in exon 20. Methods: 45 blood samples were collected from patients diagnosed with BC. DNA was extracted and selected regions were amplified by PCR using three sets of primers - two within exon 11 and one within exon 20 of BRCA1. Subsets of 10 samples were selected for each primer set (30 PCR products) and sequenced. Sequences were analyzed using various bioinformatics tools. Results: Two missense mutations were found, Q356R (rs1799950) in one patient (27 years old) and a novel SNP, V1736D, in three premenopausal patients (≤45 years), which were located within exons 11 and 20, respectively. Both detected variants were heterozygous, a status found in all patients detected with such monoallelic variation. Both missense variants underwent in silico analysis. The well-known mutation, rs1799950, was predicted to alter the protein activity, conferred by a mutant residue (R-Arg), owing to the position with a bigger size and positive charge. The novel SNP, V1736D, was predicted to play a role in the pathogenesis of BC. Conclusion: Both variants require further investigation, firstly to assess their contribution to BC and secondly to determine their potential diagnostic value when assessed in a larger population.
Impact of Displaying Inpatient Pharmaceutical Costs at the Time of Order Entry: Lessons From a Tertiary Care Center
Authors: Conway Sarah J. , Brotman Daniel J. , Pinto Brian L. , Merola David , Feldman Leonard S. , Miller Redonda G. , Shermock Kenneth M.
Published: August 2017

BACKGROUND

A lack of cost‐conscious medication use is a major contributor to excessive healthcare expenditures in the inpatient setting. Expensive medicines are often utilized when there are comparable alternatives available at a lower cost. Increasing prescriber awareness of medication cost at the time of ordering may help promote cost‐conscious use of medications in the hospital.

OBJECTIVE

To evaluate the impact of cost messaging on the ordering of 9 expensive medications.

DESIGN

Retrospective analysis of an institutional cost‐transparency initiative.

SETTING

A 1145‐bed, tertiary care, academic medical center.

PARTICIPANTS

Prescribers who ordered medications through the computerized provider order entry system at the Johns Hopkins Hospital.

METHODS

Interrupted time series and segmented regression models were used to examine prescriber ordering before and after implementation of cost messaging for 9 high‐cost medications.

RESULTS

Following the implementation of cost messaging, no significant changes were observed in the number of orders or ordering trends for intravenous (IV) formulations of eculizumab, calcitonin, levetiracetam, linezolid, mycophenolate, ribavirin, and levothyroxine. An immediate and sustained reduction in medication utilization was seen in 2 drugs that underwent a policy change during our study, IV pantoprazole and oral voriconazole. IV pantoprazole became restricted at our facility due to a national shortage (–985 orders per 10,000 patient days; P < 0.001), and oral voriconazole was replaced with an alternative antifungal in oncology order sets (–110 orders per 10,000 patient days; P = 0.001).

CONCLUSIONS

Prescriber cost transparency alone did not significantly influence medication utilization at our institution. Active strategies to reduce ordering resulted in dramatic reductions in ordering.

Province of Aceh has basic immunization coverage toddler lowest in Indonesia in 2015. even though, this province has Posyandu and Puskesmas ratio per population of the highest in the western region of Indonesia. This data their concerns regarding immunization coverage has not been handled well in Aceh Province. This papers aims to identify variables that affect the status of complete basic immunization of children aged 12-59 months in Aceh by using ordinal logistic regression analysis. Ordinal logistic regression model used is proportional odds models. Data are obtained from Susenas 2015 that was held in March 2015 by BPS-Statistic of Indonesia. Based on the results of processing data, known only 37.7% of children aged 12-59 months in the province of Aceh in 2015 which gets fully immunized, the remaining 50.6% receive primary immunization but is not complete, even about 11.7% have not received basic immunization at all. From the proportional odds model results showed that the number of children born to mothers (odds ratio = 0.88), maternal age at delivery (odds ratio = 1.03), the level of maternal education (odds ratio = 1.22), and the educational level of the household (odds ratio = 1,2) have a significant impact on the status of complete basic immunization of children. Future studies are expected to include the element of timeliness and add other variables and also with other models in ordinal logistic regression.Keywords:Immunization, Ordinal Logistic Regression, Proportional Odds, Susenas

Human Development Index is one of the indicators to measure the success of a region in the field of human development sector. There are several factors that affect Human Development Index, such as life expentancy, the literacy rate, the average length of the school, and the index of purchasing power. The aim in this paper is to analyze the relationship between factors that affect Human Development Index in Yogyakarta using regression analysis. One of the assumptions of classical regression is not going multicollinierity. Multicollinierity cause misinterpretation of regression coefficients with Ordinary Least Square (OLS) method. One method used to overcome multicollinierity is Partial Least Square (PLS). The result of Human Development Index data analysis showed there was a high correlation between the predictor variables or in other words going multicollinierity, so using PLS method, we obtained adjusted R2 of 99.3% Human Development Index variables can be explained by the four predictor variables. By using PLS method, multicollinierity resolved in the problem of violation in the linear regression assumption. Keywords: IPM, OLS, regression, PLS.

Dempsey, GM, Gibson, NV, Sykes, D, Pryjmachuk, BC, and Turner, AP. Match demands of senior and junior players during International Rugby League. J Strength Cond Res 32(6): 1678–1684, 2018—This study aims to quantify and compare the positional game demands of international junior and senior rugby league competition for the first time. Global positioning system (GPS) and video analysis were used to track 118 elite male rugby league players (57 seniors aged 28.7 ± 4.4 years; 61 juniors aged 17.2 ± 0.5 years) over 10 international matches (6 senior; 4 junior) characterized as either forwards (n = 67) or backs (n = 51). There were significant increases in the offensive carries (0.18 cf. 0.09 n·min−1; r = 0.56) and defensive tackles (0.36 cf. 0.23 n·min−1; r = 0.3) between senior and junior players, and forwards and backs (0.16 cf. 0.09; r = 0.34 and 0.41 cf. 0.14; r = 0.52), respectively. Running demands were significantly greater in backs than forwards (independent of playing level) for total distance (6,962 ± 1,263 m cf. 4,879 ± 1,824 m; r = 0.55), individualized high-speed distances (310 ± 158 m cf. 250 ± 171 m; r = 0.2), high-intensity accelerations (28.7 ± 12.1 m·s−1 cf. 21.9 ± 11.7 m·s−1; r = 0.27), and decelerations (57.2 ± 18.3 m·s−1 cf. 43.0 ± 17.8 m·s−1; r = 0.38). Positional differences were eliminated when reported relative to minutes played. From a practical perspective, although running demands relative to time on the pitch may prepare junior players for senior competition, it is not representative of the increased body mass and contact frequency within the senior game. Coaches should therefore reflect these differences within their physical preparation programs to prepare junior athletes accordingly for progression to the senior level.

Damping of spikes in an array of coupled oscillators by injection of sinusoidal current is studied both electronically and numerically. The effect is investigated using an array consisting of thirty mean-field coupled FitzHugh–Nagumo-type oscillators. The results are considered as a possible mechanism of the deep brain stimulation used to avoid the symptoms of the Parkinson's disease.
The passivity of adaptive output regulation of nonlinear exosystem with application of aircraft motions
Authors: Kumar R. Ravi Ravi , Cao Jinde , Alsaedi Ahmad
Published: August 2017

This paper deals with passivity of adaptive output regulation of nonlinear exosystem. It is shown that factorisable low-high frequency gains and harmonic uncertainties are estimated to the exogenous signals with adaptive nonlinear system. The design methodology guarantees asymptotic regulation in the case where the dimension of the regulator is sufficiently large in relation, which affects the number of harmonics acting on the system. On the other hand, harmonics of uncertain amplitude, phase, and frequency are the major sources, and the bounded steady-state regulation error ensures that adaptive nonlinear system is globally asymptotically stable via passivity theory. Kalman–Yacubovitch–Popov property provides that the uncertain adaptive nonlinear system is passive. Finally, specific examples are shown in order to demonstrate the applicability of the result.
Petrogenetic significance of the eclogites from the Arquía Complex on southwestern Pijao, Central Cordillera (Colombia Andes)
Authors: Ríos-Reyes Carlos Alberto , Castellanos-Alarcón Oscar Mauricio , García-Ramírez Carlos Alberto
Published: August 2017

Las eclogitas descubiertas en el suroeste de Pijao, Cordillera Central (Colombia Andes), son ricas en almandino (Xalm = 0.50-0.58; XFe = 0.69-0.83) y grosularia (Xgrs = 0.25-0.30), con cantidades menores de piropo (Xprp = 0.12-0.23) y relativamente baja espesartina (Xsps = 0.01-0.05), y la onfacita presenta contenidos de jadeíta, acmita y augita en el clinopiroxeno analizado de 7,00, 3,19 y 89,80% en moles; XMg= 0.82. Las eclogitas sufrieron una trayectoria PT en sentido horario con un ligero aumento de temperatura posterior al Ppeak (a 10.5 kbar y 535°C) a un máximo (Tpeak) a 8.5 kbar and 575°C y un posterior enfriamiento durante la descompresión a 4.5 kbar and 530°C. Los datos geoquímicos indican protolitos que corresponden a basaltos de tipo dorsales oceánicas normales (NMORB). Todas estas características sugieren que los remanentes ofiolíticos están involucrados en la subducción y arquitectura final del Complejo Arquía. La progresiva convergencia condujo a la formación de las asociaciones de la facies eclogites a la máxima profundidad en la corteza continental. Las eclogitas reportadas en este estudio representan un excelente ejemplo de rocas metamórficas de alta presión en cinturones orogénicos, muy útil para la comprensión de subducción de placas y los procesos de colisión de los continentes.
Foco na forma e o ensino de Inglês como L2/L3
Authors: Saraiva Pasca Maria Alejandra , Spinassé Karen Pupp
Published: August 2017

Grammatical and lexical similarities between languages can help promote adult language learning. However, even when learners are provided with a lot of input in the L2, they may not notice certain similarities and differences between their L1 and the L2 in the classroom if the linguistic structure is not salient. The purpose of this article is to discuss the benefits of making grammatical and lexical comparisons among languages, such as proposed in the EuroCom Project, and the importance of using a Meaning and a Form Focused Instruction with corrective feedback when teaching L3 learners, based on different studies carried out with multilinguals. The more the Brazilian learners of English as a second or third language notice the similarities among English, Spanish and Portuguese, the more advantage they will take of their prior linguistic knowledge, facilitating the L3 learning process.
Native-speakerism and English without Borders Program: investigating language ideologies through a language policy
Authors: Passoni Taisa Pinetti
Published: August 2017

English without Borders (EwB) is a Brazilian government-sponsored Program created to enhance linguistic proficiency of potential candidates for outward mobility. Assuming that language ideologies embody as well as are embodied by language policies, this paper aims at examining the native-speakerism ideology. It draws on texts comprising instances of enactment and interpretations of EwB in addition to evidences posed by decisions arising from its implementation to examine how native-speakerism is positioned through the Program. Building on critical language policy approach, it employs critical discourse analysis resources to investigate how native-speakerism is challenged or reinforced by the agenda implemented by EwB. Evidences point to the overlapping of deconstructing and corroborating perspectives, especially regarding local interpretations posed by the Language Center coordinators whose considerations about the linguistic diversity of English are marked by ambivalent thoughts on the issue. The coexistence of such tensions indicates the pervasive nature of native-speakerism concerning English in Brazil.

Mexican birds use according to environmental officers
Authors: Roldán-Clarà Blanca , López-Medellín Xavier , Calderón de la Barca Nelly , Leyva Claudia , Espejel Ileana
Published: August 2017

Birds are used in México for subsistence income and have traditionally been part of local cultural heritage. A group of people called pajareros are required by law to apply for permits for harvesting and selling birds, which are authorized by Mexican environmental and wildlife government officers mostly for subsistence use. While environmental manager officers interact with stakeholders as part of their work, how they actually interrelate with pajareros and make final decisions remains unclear. Therefore, we describe regulation of bird use in Mexico, analyze criteria applied, and provide the opinions of the four key officers involved in natural resource management obtained in open interviews held during 2012. Officers have a stereotyped view about pajareros and a close, sometimes conflicting relation with them, express good knowledge of social-environmental conflict related with songbirds, and decide songbird harvest rates based on the three pillars of sustainability, but prioritizing environmental laws over social needs.
FinTech and Financial Innovation: Drivers and Depth
Authors: Schindler John
Published: August 2017

This paper answers two questions that help those analyzing FinTech understand its origins, growth, and potential to affect financial stability. First, it answers the question of why "FinTech" is happening right now. Many of the technologies that support FinTech innovations are not new, but financial institutions and entrepreneurs are only now applying them to financial products and services. Analysis of the supply and demand factors that drive "traditional" financial innovation reveals a confluence of factors driving a large quantity of innovation. Second, this paper answers the question of why FinTech is getting so much more attention than traditional innovation normally does. The answer to this question has to do with the 'depth' of innovation, a concept introduced in this paper. The deeper an innovation, the greater the ability of that innovation to transform financial services. The paper shows that many FinTech innovations are deep innovations and hence have a greater potential to change financial services. A greater potential to transform can also lead to a greater chance of affecting financial stability.
Análisis comparativo de indices de caries dentales a partir de muestras de sitios arqueológicos del Holoceno tardío de la República Argentina
Authors: Menéndez Lumila Paula , Miranda De Zela Paula
Published: August 2017

El análisis de las caries dentales en muestras bioarqueológicas permite estudiar la proporción de carbohidratos que tuvo la dieta de dichas poblaciones. La revisión de las investigaciones de este tipo realizadas en Argentina permite indicar que hay dos maneras de analizar y presentar los resultados, en función del número total de individuos y/o del total de piezas dentales por muestra. El objetivo de este trabajo es realizar un análisis de la distribución de las caries dentales en cuatro muestras bioarqueológicas del Holoceno tardío de distintas regiones de Argentina empleando estas dos maneras de procesas los datos, definidas aquí como índices, con el fin de comparar, interpretar y discutir los resultados obtenidos. Para ello, se relevaron las caries presentes y se calcularon los índices en función del número de individuos (IA) y del total de piezas dentales (IB) por muestra. Se realizaron gráficos de caja y una prueba de χ2 a para evaluar la existencia de diferencias en la distribución de los valores de caries utilizando ambos índices. Finalmente se realizaron correlaciones entre los índices y los datos provenientes de estudios isotópicos de 13C y 15N. Se pudo observar que no existen diferencias significativas en los valores de caries entre los distintos grupos cuando se considera el IA y el IB, sino que por el contrario las tendencias son las mismas. Asimismo, ambos índices se asocian con la variación de 13C, y la variación del IA se asocia con los valores de 15N. Se resalta la importancia de utilizar ambos índices complementariamente ya que estos proveen distinto tipo de información y se recomienda también que en las investigaciones se expongan los datos que permitan calcularlos para que los datos generados sean comparativos.
Análisis bioarqueológico de los restos de arroyo El Siasgo, (supuesto Homo caputinclinatus de Ameghino 1910)
Authors: Escosteguy Paula Daniela , Scabuzzo Clara , González María Isabel
Published: August 2017

Las investigaciones arqueológicas desarrolladas en la Depresión del río Salado durante las últimas tres décadas permitieron profundizar en el conocimiento de los grupos prehispánicos que vivieron allí durante el Holoceno tardío. Como resultado de los trabajos de campo en la microrregión, se conocen tres sitios con restos humanos (La Guillerma Ñandú, La Guillerma 1 y La Guillerma 5), totalizando un número mínimo de seis individuos inhumados de manera aislada. En esta contribución se suma, a la información precedente, el primer estudio bioarqueológico de un esqueleto recuperado por Carlos Ameghino en el arroyo El Siasgo a principios del siglo XX. El objetivo es presentar los resultados del análisis bioarqueológico de este esqueleto, así como el fechado radiocarbónico obtenido. Se busca así aportar a la revisión de un caso de singular importancia histórica a través de la aplicación de un marco teórico y metodológico renovado. Como resultado de los análisis bioarqueológicos se pudo establecer que los restos corresponden a un individuo juvenil, de entre 12 y 15 años, que habría sido inhumado en posición primaria y que presentaba el cráneo deformado de manera circular. Se obtuvo, para este esqueleto, un fechado de ca. 3500 años AP, que es el más antiguo para la depresión del río Salado. Los análisis isotópicos reflejan que la dieta del individuo fue mixta e incluyó la ingesta, en pequeñas cantidades, de alimentos marinos. Finalmente, estos resultados son integrados a la información bioarqueológica disponible para el área.
Análisis de isótopos estables en individuos subadultos del sitio arqueológico Los Amarillos (Quebrada de Humahuaca, Jujuy)
Authors: Killian Galván Violeta Anahí , Seldes Verónica
Published: August 2017

Presentamos los resultados del análisis de isótopos estables en la fracción orgánica (δ13Cco y δ15N) e inorgánica (δ13Cap) del registro óseo o dental de 22 individuos subadultos humanos hallados en el sitio arqueológico Los Amarillos (Período de Desarrollos Regionales e Inca, provincia de Jujuy). Para el análisis isotópico se consideraron los estudios longitudinales en poblaciones actuales, los cuales han mostrado que durante los primeros meses de vida se detectan valores isotópicos afectados por el amamantamiento. Estos estudios requieren acotar al máximo los rangos etarios de los individuos bajo análisis, lo cual, muchas veces es dificultoso dados los múltiples procesos tafonómicos que pueden fragmentar la muestra, así como también por los límites que presentan los métodos analíticos disponibles. No obstante, se ha podido inferir una edad de destete temprana, lo cual habría favorecido la disminución de los intervalos entre nacimientos, proceso acorde con el aumento demográfico propuesto para el período cronológico asociado a la ocupación del sitio arqueológico.
