La cartografía conceptual y su utilidad para el estudio de la lectura como práctica históricocultural: El Quijote como ejemplo
Authors: Vivas Moreno Agustín , Martos García Aitana
Published: June 2017

El presente trabajo tiene por objeto exponer las claves sobre la utilización de las modernas cartografías conceptuales para el estudio de la lectura como práctica histórico–cultural. Tras una breve revisión de las prácticas de lectura desde la alfabetización clásica hasta sus nuevas funciones en el siglo XXI, examinaremos la cartografía conceptual como metodología de investigación, centrándonos en el procedimiento concreto de las cuadrículas de dominio, que pueden aliarse con técnicas documentales (como por ejemplo un tesauro que se complementa perfectamente con la cuadrícula) para producir avanzados instrumentos de información. A modo de ejemplo, veremos cómo analizar la lectura en El Quijote a partir de dicha metodología, basada en una tesis de doctorado leída en 2008. En este caso concreto, las cuadrículas de dominio se complementan con un tesauro elaborado ad hoc, de modo que los hiperónimos de las cuatro cuadrículas de dominio (Creación, Instrucción, Materialidad y Preservación) corresponden a las cabezas de jerarquía del tesauro. Así, conseguimos una simbiosis cartografía / lenguaje documental que se materializa en un sistema de información integral.
Las necesidades de información en la comunidad de vitivinicultores de la región de Baja California: una aproximación.
Authors: López Franco Fermín
Published: June 2017

Los vitivinicultores manifiestan necesidades de información y comportamiento informativo, pero no conocen los aspectos de este proceso. Por ejemplo, no se tiene la certeza del lugar y las fuentes de información a las que acuden a fin de llevar a cabo sus diferentes actividades como son la selección de la uva de acuerdo con la zona, la siembra, el cuidado, la cosecha, producción y comercialización de la vid, además del embotellamiento de sus productos. En este artículo se presentan algunos aspectos relacionados con la definición de las necesidades de información, así como una breve descripción de éstas en el área agrícola y biológica al no encontrar información que se relacione directamente con los vitivinicultores. La metodología fue una investigación documental y de campo, mientras que la técnica que se empleó fue una encuesta que utilizó como instrumento la cédula de entrevista. Además se presentan algunos resultados obtenidos relacionados con necesidades de información de esta comunidad.

Los modelos de evaluación aplicados a los programas educativos de educación superior: una perspectiva bibliotecológica
Authors: Gómez Briseño Jorge , Mora Terrazas Manuel
Published: June 2017

La evaluación de los programas educativos como una forma de mejorar su calidad ha sido uno de los temas a debate desde finales del siglo XX e inicios del XXI. Más allá de las discrepancias en torno a sus resultados, la evaluación de los programas educativos es un método que ha comprobado su efectividad y eficiencia para conocer sus fortalezas y áreas de oportunidad, a partir de su vinculación con la universidad de la cual depende, así como con su infraestructura e incluso aspectos particulares como su desarrollo académico y el de su investigación. En México los Comités Interinstitucionales para la Evaluación de la Educación Superior (CIEES) se encargan de evaluar más de 3,400 programas académicos (técnico superior universitario, licenciatura y posgrado), mediante metodologías y marcos de evaluación rigurosos, con criterios y estándares internacionales semejantes a los de una investigación científica. En esta inercia los programas mexicanos de Licenciatura en Bibliotecología se han sometido a los procesos de evaluación interinstitucional de los CIEES y han sido reconocidos en su mayoría por su calidad académica, lo que ha redundado en mejoras sustanciales en los programas que se someten a su revisión. Con respecto al nivel de posgrado, algunas maestrías en Bibliotecología han sido evaluadas por el Marco de Referencia para la Evaluación y Seguimiento de Programas de Posgrado del Consejo Nacional de Ciencia y Tecnología (CONACYT), pero no existe un modelo específico para dichos programas, por lo que con base a lo establecido por la Sección de Educación y Capacitación de la IFLA, se considera oportuno proponer el desarrollo de un modelo de evaluación para serle aplicado específicamente a dichos programas.

A Büntető Törvénykönyvről szóló 2012.évi C. törvény újabb jelentős szabályozástörténetiállomást jelent a magyar büntetőjogban. A szakzsargonban nemes egyszerűséggel, csak újBtk.-nak nevezett kódex különböző kritikákat kapott mind jogirodalom, mind a jogalkalmazásművelőitől.2 Az észrevételek azonban átsiklottak egy olyan szabályozási megoldás felett,amelynek létjogosultsága – véleményem szerint – meglehetősen vitatható. Az egymásnakfeszülő bírósági ítéleti indokolások is bizonyítják, hogy az életveszélyt okozó testi sértéstényállása az egyik legproblematikusabb szabályozási megoldás az „1978-as” büntető anyagikódexünkben. E tanulmányban a fenti téma körüljárására teszek kísérletet.

The expropriation is a neglected legal institution in the Hungarian law, especially in the civil law. Although the expropriation usually appears in the civil law codes of the European states, it is ambiguous of the aspect of the civil law. However, it cannot be ignored that the civil law aspects of the expropriation are very important.In the civil law literature the expropriation is discussed either as the original way of acquisition of property or as the limit of the public property relations.My lecture is about the theoretical problems of the expropriation in the system of civil law. This article will provide an overview of doctrinal opinions about expropriation law in the delayed codification and in the new Hungarian civil law codex.
szerződési szabadság gazdaságszabályozó szerepe
Authors: Török Éva
Published: June 2017

The freedom of contract has an economic regulating rule, both on individual and on communal level; secures either the enforcement of the law of the self-determination of the parts, or the possibility of market participation.

Gwartney and Lawson, elaborators of the conception of the economic freedom, said that the capstones of the economic freedom are the freedom for the decisions and for the acts of the persons, moreover the volunteering of the exchange, the freedom of the competition, the protection of the persons and their properties.

Several indicators are available for measuring the economic freedom. One of them is the index of the Canadian Fraser Institute Economic Freedom of the World; furthermore it is one of the most respected indicators. This index investigates the rate of the economic freedom by using 42 factors grouped to five parts. These five components are the legal system and the protection of the ownership, size of the state, reliable, so stable valued money, the freedom of the foreign trade, the capital market and the regulation of the business. The last four items can be identified as the freedom of the contract.

Der Verbraucherschutz korrigiert durch die rechtliche Regelung, durch Ausbau eines interdisziplinieren Rechtsinstrumentsystems versichert es Rechtsschutz für die Verbraucher in schwächerer Position. Durch rechtlichen Instrumenten wird die optimale Gleichgewichtslage wiederherstellt, demnoch werden die optimalen Verhältnisse geschafft, unter denen die Verbraucher freie Kaufsentscheidungen treffen können und nach eigenen Bedürfnissen „konsumieren” können. Die modernen Rechtsysteme haben als eigenes das ideale Leitbild des Schutzes der schwächeren Partei, diesbezüglich der Schutz vom hohen Niveau der Verbraucherinteressen kann als dritte Generation der Menschenrechte begriffen werden. Also der Verbraucherschutz wurde inzwischen die Sicherung für Lebensniveau der Europabürger und dient neulich auch als Mittel erneuerter Impulze für europäische Wirtschaft zu geben.

Ziel dieses Artikels ist zu untersuchen, ob irgendwelche Harmonisierung in Rahmen einer Rahmenrichtlinie oder Vereinheitlichung der Verbraucherrechte in Europa eigentlich verwirklich werden könnte. Vor den Feststellungen der endgültigen Konklusionen müssen wir genau anschauen ob die europäischen Verbraucherregelungen gemeinsame Wurzeln oder gemensame Instrumente verfügen.

A vagyoni értékű jogok apportálhatósága és az egységes szabályozás hiányának problematikája
Authors: Lehoczki Zóra Zsófia
Published: June 2017

According to the new Hungarian Civil Code, the funders of the legal entities have to make contributions to the authorised capital and the two forms of these contributions are the contribution is cash and the contribution in kind. The regulation states that proprietary rights can also be transferred to the capital of businness accociations, by those funders, who are entitled to demise them.

The judicial practice unanimously defined the rules in those cases, when the object of contribution in kind is a certain proprietary right, especially when the right is connected to the real estate. On the other hand, the Civil Code does not contain a list of those proprietary rights, which can be transferred to the authorised capital and unfortunately, different acts contain different lists of these rights.

The three mentioned acts are the following: the personal income tax act, the act about the fees and the accounting act. All of them contain a list of proprietary rights and some of the items are regulated by all the three of them but most of the items are different, which means it is impossible to create an accurate list of these rights. For example, the list in the personal income tax act contains only five items, on the other hand, the accounting act contains two lists and both of them are unfinised.

Because of the lack of unified rules, it is impossible to define which proprietary rights can become the objects of contribution in kind and this misfortunate situation causes a lot of unwanted indefinability and states a lot of questions.

In my essay I introduce this problem and I use a chart to illustrate the differences between the mentioned lists. In my opinion, this problem could be solved with an unified list, which is normative for every regulation in connection with the proprietary rights or the Civil Code should contain a list of those proprietary rights, which can be the objects of contribution in kind.

n my paper, I dealt with the divided trial system, because in the Conception of the New Code of Civil Procedure arised the idea, that the first-instance procedure will be regulated by the divided trial system. During my studies, I researched the trial system of the Act I of 1911, and I analyzed the sentencing practice in this era.

First, I presented the matter of the trial system, as well as the two dominant trends in Hungary relating to the creation of civil action. The difference between the two trends, that distinct mesne process creates the civil action. According to one of them, the civil action is created when the defendant gets the statement of claim, or, on the other hand, when the defendant submits countermotion.

In the next chapter, I intended to present the point of intersection of action, which legal institution separates the first-instance procedure to pre-trial hearing and the trial on the merits.

After this chapter, I reportedtheresults of sentencing practice and cametotwoconclusions. Ontheonehand, thepre-trialhearinghangedfirefor a longtimebecause of theappealproceedings.

Spider Diagram for Tubular Expansion with Restraints
Authors: Marketz F , Al-Hiddabi SA
Published: June 2017

The aim of this study is to explain the mechanics of tubular expansion in irregularly shaped boreholes such as those frequently observed in the upper Natih reservoirs. Statistical analysis of borehole data does not indicate a strong correlation between the non-circularity and expanded tubular’s in such boreholes. A two-dimensional (2-D) finite element model was developed using commercial software to determine the non-circularity of an expanded tubular and those data were compared with the measured values. A parametric study was also conducted and spider plots were generated to determine the amount of irregularity in the expanded tubulars so that optimum operational parameters could be identified to limit cross-section irregularities during the expansion process.
Effect of Mineral Filler Type and Particle Size on the Engineering Properties of Stone Mastic Asphalt Pavements
Authors: Muniandy R , Aburkaba E , Taha R
Published: June 2017

This study examines four types of industrial and by-product waste fillers, namely limestone dust (LSD), which was the reference filler; ceramic waste dust (CWD); coal fly ash (CFA), and steel slag mixture (SSD). The filler consisted of an aggregate (10% of total weight) with three proportions: 100% passing 75μm, 50% passing 75μm/20μm, and 100% passing 20μm. Comprehensive laboratory tests were performed to determine the impact of different types and particle sizes of fillers on the engineering and mechanical properties of fine mastics and stone mastic asphalt mixture. The results indicate that the application of industrial by-products used as fillers improves the engineering properties of stone mastic asphalt mixtures. The increased stiffness due to the addition of the filler is represented by an increase in the softening point, viscosity, stability, and resilient modulus, as well as a decrease in penetration. The optimum asphalt content increased with the decrease in filler particle size for LSD and SSD, and decreased for CWD and CFA. It was also determined that the filler type and particle size has a significant effect on the mixture properties. Among these three proportions, the samples prepared with the filler size proportion of 50/50 gave the best value in terms of stability, Marshall quotient, and resilient modulus than the other filler size proportions.
Compensated Medium Voltage 6-Pulse CSR Using Shunt Active Power Filters: Three Different Configurations
Authors: Hamad MS , Masoud MI
Published: June 2017

The 6-pulse controlled AC/DC converter produces harmonics. The input current total harmonic distortion and the input power factor, which is firing delay angle dependent, are major drawbacks, and a compensation technique is mandatory. This paper introduces a compensated 6-pulse current sourcecontrolled rectifier with a shunt active power filter (APF ) in different configurations. The shunt APF  with predictive current control is coupled to the 6-pulse systems in three different compensation configurations. The APF  is connected either directly to the front-end transformer primary or secondary side or via a transformer to reduce the filter side voltage. The comparison between these configuration is introduced; each configuration has merits and demerits. The comparison cannot be genuine. Simulation results are presented for a medium voltage converter which is scaled to allow low-voltage experimental confirmation.

In the present work, an attempt has been made to use the grey-based fuzzy logic method to solve correlated multiple response optimization problems in the field of flux cored arc welding. This approach converts the complex multiple objectives into a single grey-fuzzy reasoning grade. Based on the grey-fuzzy reasoning grade, optimum parameters are identified. The significant contributions of parameters are estimated using analysis of variance (ANOVA). This evaluation procedure can be used in intelligent decision making for a welding operator. The proposed and developed method has good accuracy and competency. The proposed technique provides manufacturers who develop intelligent manufacturing systems a method to facilitate the achievement of the highest level of automation.
Identification of Pavement Distress Types and Pavement Condition Evaluation Based on Network Level Inspection for Jazan City Road Network
Authors: Mubaraki M
Published: June 2017

The first step in establishing a pavement management system (PMS) is road network identification. An important feature of a PMS is the ability to determine the current condition of a road network and predict its future condition. Pavement condition evaluation may involve structure, roughness, surface distress, and safety evaluation. In this study, a pavement distress condition rating procedure was used to achieve the objectives of this study. The main objectives of this study were to identify the common types of distress that exist on the Jazan road network (JRN), either on main roads or secondary roads, and to evaluate the pavement condition based on network level inspection. The study was conducted by collecting pavement distress types from 227 sample units on main roads and 500 sample units from secondary roads. Data were examined through analysis of common types of distress identified in both main and secondary roads. Through these data, pavement condition index (PCI) for each sample unit was then calculated. Through these calculations, average PCIs for the main and secondary roads were determined. Results indicated that the most common pavement distress types on main roads were patching and utility cut patching, longitudinal and transverse cracking, polished aggregate, weathering and raveling, and alligator cracking. The most common pavement distress types on secondary roads were weathering and raveling, patching and utility cut patching, longitudinal and transverse cracking, potholes, and alligator cracking. The results also indicated that 65% of Jazan's main road network has an average pavement condition rating of very good while only 30% of Jazan's secondary roads network has an average pavement condition.
On Sequence Lengths of Some Special External Exclusive OR Type LFSR Structures – Study and Analysis
Authors: Ahmad A , Al Maashri A
Published: June 2017

The study of the length of pseudo-random binary sequences generated by Linear- Feedback Shift Registers (LFSRs) plays an important role in the design approaches of built-in selftest, cryptosystems, and other applications. However, certain LFSR structures might not be appropriate in some situations. Given that determining the length of generated pseudo-random binary sequence is a complex task, therefore, before using an LFSR structure, it is essential to investigate the length and the properties of the sequence. This paper investigates some conditions and LFSR’s structures, which restrict the pseudo-random binary sequences’ generation to a certain fixed length. The outcomes of this paper are presented in the form of theorems, simulations, and analyses. We believe that these outcomes are of great importance to the designers of built-in self-test equipment, cryptosystems, and other applications such as radar, CDMA, error correction, and Monte Carlo simulation.
Comparative Analysis of Maximum Power Point Tracking Controllers under Partial Shaded Conditions in a Photovoltaic System
Authors: Ramaprabha R. , Chitra S.P.
Published: June 2017

Mismatching effects due to partial shaded conditions are the major drawbacks existing in today’s photovoltaic (PV) systems. These mismatch effects are greatly reduced in distributed PV system architecture where each panel is effectively decoupled from its neighboring panel. To obtain the optimal operation of the PV panels, maximum power point tracking (MPPT) techniques are used. In partial shaded conditions, detecting the maximum operating point is difficult as the characteristic curves are complex with multiple peaks. In this paper, a neural network control technique is employed for MPPT. Detailed analyses were carried out on MPPT controllers in centralized and distributed architecture under partial shaded environments. The efficiency of the MPPT controllers and the effectiveness of the proposed control technique under partial shaded environments was examined using MATLAB software. The results were validated through experimentation.

Published: June 2017

Sea water intrusion in ground water sources has made brackish water desalination a necessity in Oman. The application of capacitive deionization (CDI) for the deionization of ground water samples from wells in Al-Musanaah Wilayat is proposed and demonstrated. A CDI cell is fabricated using nanoporous activated carbon cloth (ACC) as the electrodes and is shown to be power efficient for desalting ground water samples with total dissolved solids (TDS) of up to 4,000 mg/l. The CDI cell was able to remove up to 73% of the ionic scaling and fouling contaminants from brackish water samples. The power consumption for deionization of brackish water was estimated to be 1 kWh/m3 of desalinated water, which is much lower than the power required to process water with equivalent TDS by the reverse osmosis processes. The CDI process is elaborated, and observations and analysis of the ion adsorption characteristics and electrical properties of the capacitive cell are elucidated.
Drag Reduction Properties of Nanofluids in Microchannels
Authors: Abdulbari H.A. , Ming F.L.W.
Published: June 2017

An experimental investigation of the drag reduction (DR) individualities in different sized micro channels was carried out with nanopowder additives (NAs) (bismuth(III) oxide, iron(II/III) oxide, silica, and titanium(IV) oxide) water suspensions/fluids. The primary objective was to evaluate the effects of various concentrations of NAs with different microchannel sizes (50, 100, and 200 µm) on the pressure drop of a system in a single phase. A critical concentration was observed with all the NAs, above which increasing the concentration was not effective. Based on the experimental results, the optimum DR percentages were calculated. The optimum percentages were found to be as follows: bismuth III oxides: ~65% DR, 200 ppm and a microchannel size of 100 µm; iron II/III oxides: ~57% DR, 300 ppm, and a microchannel size of 50 µm; titanium IV oxides: ~57% DR, 200 ppm, and a microchannel size of 50 µm, and silica: 55% DR, 200 ppm, and a microchannel size of 50 µm.

Authors: Al-Abdul Wahhab H.I. , Abdullah G.M.S.
Published: June 2017

This paper presents a study carried out to evaluate and compare the permanent deformation of marginal soils. Under consideration were marl, sabkha and dune sand stabilized with foamed and emulsified sulfur asphalt (FSA, ESA) with mixes of the same soils stabilized with conventional foamed and emulsified asphalt (FA, EA) for road base construction. Designed mixes at their optimum asphalt content were evaluated for the dynamic resilient modulus (MR) at 22 °C and 40 °C and dynamic triaxial at three levels of deviatoric stress and at 22 °C and 40 °C. The wheel tracking (WT) test was carried out at 22 °C. Permanent deformation of stabilized mixes with optimum binder contents was modeled and simulated using dynamic triaxial and WT tests. The developed models were calibrated to predict rutting using VESYS 5W software. Results indicated that the FSA increased rutting resistance as compared to conventional FA mixes. On the other hand, ESA increased the rutting susceptibility of marl soil as compared to EA. The calibrated models of rutting prediction were found to predict the rut depth with 90% accuracy.
Effect of Sediment Density on the Bed Topography in a Channel Bend Using Numerical Modeling
Authors: Vaghefi M. , Safarpoor Y. , Hashemi S.S.
Published: June 2017

In this paper, the bed topography of a channel at a 90-degree bend was studied at the T-shaped spur dike installed at the middle of the outer bank. Numerical analyses were performed with the Sediment Simulation in Intakes with Multiblock Option (SSIIM) model. Three relative curvatures (R/B =  2, 3, and 4) related to the three sediment densities (P  = 2.35, 2.5, and 2.65) were modeled in nine cases and the effects of sediment density on the bed scour patterns were studied. It was observed that the maximum amount of scour occurred near the head of the dike wing at the dike’s upstream, and the maximum amount of sedimentation occurred at the inner bank of the bend exit. By increasing the sediment density when R/B  = 4, the maximum scour and sedimentation decreased to 27.41% and 46.15%, respectively. When R/B  = 3, the maximum scour and sedimentation decreased to 25.93% and 23.91%, respectively. When R/B  = 2, the maximum scour and sedimentation decreased to 25.98% and 10%, respectively.
Performance Comparison of Digital Circuits Using Subthreshold Leakage Power Reduction Techniques
Authors: Kalagadda B. , Muthyala N. , Korlapati K.K.
Published: June 2017

Complementary metal-oxide semiconductors (CMOS), stack, sleep and sleepy keeper techniques are used to control sub-threshold leakage. These effective low-power digital circuit design approaches reduce the overall power dissipation. In this paper, the characteristics of inverter, twoinput negative-AND (NAND) gate, and half adder digital circuits were analyzed and compared in 45nm, 120nm, 180nm technology nodes by applying several leakage power reduction methodologies to conventional CMOS designs. The sleepy keeper technique when compared to other techniques dissipates less static power. The advantage of the sleepy keeper technique is mainly its ability to preserve the logic state of a digital circuit while reducing subthreshold leakage power dissipation.

Incorporating Equity and Resiliency in Municipal Transportation Planning: Case Study of Mobility Hubs in Oakland, California
Authors: Anderson Karl , Blanchard Samuel D. , Cheah Derek , Levitt Drew
Published: June 2017

This paper presents a multicriteria suitability analysis framework to aid municipal governments in efforts to determine optimal siting of mobility hubs in their jurisdictions. Mobility hubs are agglomerations of transportation modes that concentrate emerging shared mobility services in well-defined locations, delivering several benefits to users. These benefits include primarily increased connectivity among modes and augmentation of public transit with improved first- and last-mile connections. The framework was applied to a case study in Oakland, California. The presented methodology has the potential for broader use by transportation planners and policy makers to advance various qualitative values in their practice, including equity and resiliency, and can quantitatively inform geographic, values-oriented outcomes.
Soliton Content of Fiber-Optic Light Pulses
Authors: Mitschke Fedor , Mahnke Christoph , Hause Alexander
Published: June 2017

This is a review of fiber-optic soliton propagation and of methods to determine the soliton content in a pulse, group of pulses or a similar structure. Of central importance is the nonlinear Schrödinger equation, an integrable equation that possesses soliton solutions, among others. Several extensions and generalizations of this equation are customary to better approximate real-world systems, but this comes at the expense of losing integrability. Depending on the experimental situation under discussion, a variety of pulse shapes or pulse groups can arise. In each case, the structure will contain one or several solitons plus small amplitude radiation. Direct scattering transform, also known as nonlinear Fourier transform, serves to quantify the soliton content in a given pulse structure, but it relies on integrability. Soliton radiation beat analysis does not suffer from this restriction, but has other limitations. The relative advantages and disadvantages of the methods are compared.

Atopic dermatitis (AD) is a common chronic inflammatory skin condition characterized by intense puritus and skin dryness. The pathogenesis for AD has not been fully understood to date. Complementary therapies are very popular as effective treatment for AD among clinical practitioners. This study presents a comprehensive review of published works associated with textiles-based complementary therapies for AD treatment such as wet-wrap dressing, functionalized textiles, and the application of hydrogel techniques in the textile industry to provide a better understanding of the development and design of new textiles-based transdermal therapies.
Assessing Probabilistic Inference by Comparing the Generalized Mean of the Model and Source Probabilities
Authors: Nelson Kenric
Published: June 2017

An approach to the assessment of probabilistic inference is described which quantifies the performance on the probability scale. From both information and Bayesian theory, the central tendency of an inference is proven to be the geometric mean of the probabilities reported for the actual outcome and is referred to as the “Accuracy”. Upper and lower error bars on the accuracy are provided by the arithmetic mean and the −2/3 mean. The arithmetic is called the “Decisiveness” due to its similarity with the cost of a decision and the −2/3 mean is called the “Robustness”, due to its sensitivity to outlier errors. Visualization of inference performance is facilitated by plotting the reported model probabilities versus the histogram calculated source probabilities. The visualization of the calibration between model and source is summarized on both axes by the arithmetic, geometric, and −2/3 means. From information theory, the performance of the inference is related to the cross-entropy between the model and source distribution. Just as cross-entropy is the sum of the entropy and the divergence; the accuracy of a model can be decomposed into a component due to the source uncertainty and the divergence between the source and model. Translated to the probability domain these quantities are plotted as the average model probability versus the average source probability. The divergence probability is the average model probability divided by the average source probability. When an inference is over/under-confident, the arithmetic mean of the model increases/decreases, while the −2/3 mean decreases/increases, respectively.

We offer and test a brief psychosocial intervention, Speaking Truth to EmPower (STEP), designed to protect underrepresented minorities’ (URMs) intellectual performance and safety in science, technology, engineering, and math (STEM). STEP takes a ‘knowledge as power’ approach by: (a) providing a tutorial on stereotype threat (i.e., a social contextual phenomenon, implicated in underperformance and early exit) and (b) encouraging URMs to use lived experiences for generating be-prepared coping strategies. Participants were 670 STEM undergraduates [URMs (Black/African American and Latina/o) and non-URMs (White/European American and Asian/Asian American)]. STEP protected URMs’ abstract reasoning and class grades (adjusted for grade point average [GPA]) as well as decreased URMs’ worries about confirming ethnic/racial stereotypes. STEP’s two-pronged approach—explicating the effects of structural ‘isms’ while harnessing URMs’ existing assets—shows promise in increasing diversification and equity in STEM.

Published: June 2017

Newborn screening (NBS) programs for severe combined immunodeficiency (SCID), the most severe type of primary immunodeficiency, are being implemented in more and more countries with every passing year. Since October 2015, SCID screening via T cell receptor excision circle (TREC) quantification in dried blood spots (DBS) has been part of the Israeli NBS program. As an NBS program in its infancy, SCID screening is still evolving, making gathering input from the various programs crucial for compiling an ideal screening algorithm. The relatively high rate of consanguineous marriages in Israel, especially among non-Jews, correlates with an increased incidence of SCID. The Israeli algorithm uses a commercial kit and consists of a two-Guthrie card confirmation system prior to referral to a national immunology center. Preliminary data from the first year and a half of SCID screening in Israel has identified a surprisingly high prevalence of DNA cross-link repair protein 1c (DCLRE1C; ARTEMIS) mutations as the cause of SCID in Israel. The clinically unbiased nature of SCID screening helps unearth mild/leaky SCID phenotypes, resulting in a better understanding of true SCID prevalence and etiology.

Published: June 2017

User-based research is strongly recommended in design for older adults. The aim of this paper is to focus the attention on the poorly explored role of medical and para-medical personnel’s perspective on home health care technologies using data that have been gained during the “Active Ageing At Home” (AA@H) project. A focus group was organized at the National Institute of Health & Science on Ageing (INRCA) in Italy. Results demonstrate that several challenges deserve a stronger effort by the whole research sector on ageing and technology: (1) a leading role of the participatory design process; (2) the assessment of the added value of health technologies through robust methods; (3) the definition of an unique identity and well established practices among disciplines; (4) the creation of favorable prerequisites and conditions to the technology uptake.
Numerical Investigation of Aggregated Fuel Spatial Pattern Impacts on Fire Behavior

Published: June 2017

Landscape heterogeneity shapes species distributions, interactions, and fluctuations. Historically, in dry forest ecosystems, low canopy cover and heterogeneous fuel patterns often moderated disturbances like fire. Over the last century, however, increases in canopy cover and more homogeneous patterns have contributed to altered fire regimes with higher fire severity. Fire management strategies emphasize increasing within-stand heterogeneity with aggregated fuel patterns to alter potential fire behavior. Yet, little is known about how such patterns may affect fire behavior, or how sensitive fire behavior changes from fuel patterns are to winds and canopy cover. Here, we used a physics-based fire behavior model, FIRETEC, to explore the impacts of spatially aggregated fuel patterns on the mean and variability of stand-level fire behavior, and to test sensitivity of these effects to wind and canopy cover. Qualitative and quantitative approaches suggest that spatial fuel patterns can significantly affect fire behavior. Based on our results we propose three hypotheses: (1) aggregated spatial fuel patterns primarily affect fire behavior by increasing variability; (2) this variability should increase with spatial scale of aggregation; and (3) fire behavior sensitivity to spatial pattern effects should be more pronounced under moderate wind and fuel conditions.

Poor maternal nutrition is a major contributor to the high incidence of low birth weight deliveries in developing countries. This study aimed to assess the impact of second trimester maternal dietary intake on gestational weight gain and neonatal birth weight. A longitudinal study was conducted in a tertiary care hospital in Sri Lanka. Participants were 141 pregnant women at 18–24 weeks gestation who were followed up until delivery. Maternal dietary intake was assessed using a validated Food Frequency Questionnaire at 21.1 ± 1.8 gestational weeks. Gestational weight gain was examined at the end of 28 weeks gestation and at the end of pregnancy. Energy and nutrient intakes were calculated using NutriSurvey 2007 (EBISpro, Willstaett, Germany) nutrient analysis software, modified for Sri Lankan foods. The mean total gestational weight gain of women with low carbohydrate intake (229–429 g/day) was 2.2 kg less than that of women with moderate carbohydrate intake (430–629 g/day) (95% confidence interval (CI) 0.428–4.083 kg; p = 0.016). Similarly, babies of women with low carbohydrate intake were 312 g lighter compared with those of women with a moderate carbohydrate intake (95% CI 91–534 g; p = 0.006). Our results suggest that second trimester maternal carbohydrate intake has significant impacts on total gestational weight gain and neonatal birth weight.
