Authors: Castro Talita Egevardt de , Clemente Felippe , Lírio Viviani Silva , Teixeira Evandro Camargos
Published: October 2017

A violência e a segurança têm se tornado uma das principais preocupações no Brasil e no mundo. Observa-se um aumento constante dos indicadores da violência, principalmente da taxa de homicídios com armas de fogo. Com isso, o objetivo central do trabalho é aplicar ao contexto brasileiro as diferentes simulações em Teoria dos Jogos de confronto entre criminoso e vítima, de acordo com os modelos teóricos de Oliveira (2011) e propor políticas públicas que maximizem o bem-estar e a segurança na sociedade. Os principais resultados mostram que, dada uma sociedade em que os indivíduos possuem habilidades iguais, ofertar armas e aumentar o custo de portá-las acima da remuneração da vítima inibe o crime. Já para uma sociedade com habilidades e comportamentos diferentes, o resultado implica em crimes com armas, sendo, portanto, difícil inferir sobre políticas públicas a respeito de armas e seus impactos na criminalidade.

Published: October 2017

O presente trabalho explora o fenômeno da criminalidade nos municípios mineiros no ano de 2010. Acreditando que esse fenômeno não está distribuído aleatoriamente no espaço, podendo apresentar dependência e heterogeneidade espacial, utilizou-se modelos de econometria espacial, a saber: SARMA e GWR. Os principais resultados indicaram que os crimes contra a pessoa tendem a ser mais frequentes em áreas economicamente menos desenvolvidas. Em contrapartida, crimes contra o patrimônio são mais comuns em regiões ricas, onde há alvos viáveis para os autores dos delitos. Com relação à população de 15 a 24 anos, constatou-se que a maior concentração da população dessa faixa etária em determinada região influencia positivamente a criminalidade.

Published: October 2017

Prevalensi penyakit karang sebelumnya belum dilaporkan di perairan Padang, Sumatera Barat. Adapun tujuan penelitian ini adalah untuk mendapatkan prevalensi penyakit karang pada lokasi yang dekat dengan pantai, pertengahan dan lokasi terluar, dimana lokasi tersebut merupakan lokasi pemantauan yang berkesinambungan sejak tahun 1994 untuk data kondisi karang. Metode pengamatan yang digunakan adalah metode transek sabuk dengan ukuran 1 m kekiri dan kekanan transek garis yang memiliki panjang 30 m dan 3 ulangan. Dua jenis penyakit dan dua indicator stress karang teramati pada penelitian ini. Penyakit karang sabuk hitam (Black Band Disease, BBD) yang banyak ditemukan di Pulau Pandan (1.3%) pada kedalam 5 m. Penyakit White Syndrome (WS) terjadi di Gosong Air (0.3%). Beberapa koloni karang Montipora sp. dan Pocillopora verrucosa mengalami pemutihan di Pulau Pieh (2.1%).Focal bleaching ditemukan pada karang Galaxea sp. dan Goniastrea sp. di Gosong Gabuo (2.5%) dan pada karang Pocillopora verrucosa di Gosong Sipakal (3.9%). Penyakit BBD menginfeksi karang Montipora sp. dan Porites sp. Penyakit WS hanya menginfeksi karang Montipora sp. Karang Montipora sp, Pocillopora sp dan Porites sp banyak dan umum ditemukan di perairan Padang. Hasil ini menunjukkan bahwa infeksi penyakit karang masih tergolong rendah dan secara alamiah bisa terjadi sehingga tidak menghalangi proses pemulihan kondisi karang yang saat ini terjadi dan secara umum pada status kesehatan karang. Kata kunci: coral disease, black band disease, white syndrome, Sumatera Barat The prevalence of coral disease was previously unreported on the reefs of the Padang Shelf Reef System, West Sumatra and is relatively uncommon. The objective of this study was to get coral disease prevalence of each site which located at inshore, mid-shelf reef and off-shore reefs. The research was carried out by using belt transect method with 1 m left and right of tape as long 30 m with 3 replications. Two kinds of coral disease and two indicators of stressed coral were observed. While relatively infrequent, Black Band Disease was most common (1.3%) occurring on Pandan Island at 5m. White Syndrome occurred at Air patch reef (0.3%). A few bleached colonies of Montipora sp. and Pocillopora verrucosa were observed on Pieh Island reef (2.1%). Focal bleaching was observed on Galaxea sp. and Goniastrea sp. at Gabuo patch reefs (2.5%) and on Pocillopora verrucosa at Sipakal patch reef (3.9%). BBD infected both Montipora sp. and Porites sp. WS only infected on Montipora sp. Montipora, Pocillopora and Porites were the most common genera observed on the reefs. It suggests that coral disease infection was classified as a minor and it will not hamper coral recovery processes and coral health status in Padang Waters, West Sumatera.

Published: October 2017

The search for carotenoids in nature has been extensively studied because of their applications in foods. One treasure of the biopigment source is symbiotic-microorganisms with marine biota. The advantages of symbiont bacteria are easy to culture and sensitize pigments. The use of symbiont bacteria helps to conserve fish, coral reefs, seagrass, and seaweed. Therefore, the bacteria keeps their existence in their ecosystems. In this study, bacterial symbionts were successfully isolated from brown algae Padina sp. The bacterial symbionts had yellow pigment associated with carotenoids. The pigments were characterized using High Performance Liquid Chromatography (HPLC) with a Photo Diode Array (PDA) detector. The carotenoid pigments in the bacterial symbionts were identified as dinoxanthin, lutein and neoxanthin. Molecular identification by using a 16S rRNA gene sequence method, reveals that the bacterial symbionts were closely related to Bacillus marisflavi with a homology of 99%.

Published: October 2017

Reliable and precise species identification is important to fisheries management and conservation. However, many rays and skates in Indonesia are currently being exploited and landed into traditional fish market without a proper identification. Therefore, this study was conducted to identify species of skates and stingrays that were landed and traded in three fish markets in Indonesia (Palabuhanratu, Muara Saban, and Lampung) using molecular techniques and to determine the conservation status of the identified species based on IUCN (International Union for Conservation of Nature and Natural Resources) as well as defined by CITES (Convention on International Trade in Endangered Species). The mitochondrial cytochrome oxidase I (COI) gene was amplified by polymerase chain reaction (PCR) using a pair of primer, fish-BCL and fish-BCH. Of 29 tissue samples collected from the study sites, a total of five species were successfully identified: Dipturus chilensis (4), Himantura walga (1), Neotrygon kuhlii (11), Taeniura lymma (9) and Rhinoptera javanica (4). The Neighbor Joining phylogeny of mitochondrial lineages, based on partial COI gene sequences, the ingroup haplotypes were clustered into five main clades representing each species. The identified stingrays were being listed as vulnerable (D. chilensis and R. javanica), near threatened (H. walga and T. lymma), and data deficient (N. kuhlii) by IUCN, with two species (D. chilensis and H. walga) population were indicated decreased. Unfortunately, all of identified species have not been evaluated by CITES regarding their trade status. As a consequences, a valuable effort should be placed to create a scientific network for monitoring programmes not only on a local scale, and to make pressure on governments for adopting molecular techniques as tools for controlling and avoiding misidentification.

Published: October 2017

There are many species of macroalga grow in marine ecosystem and potentially as raw material for bioethanol resource. Bioethanol is a conversion result of carbohydrate, one of macroalgae biomass content. The exploration of macroalgae require information about  growth rate ability to determine availability in the nature. This research analyze growth rate and carbohydrate content of marine macroalga Gelidium latifolium on cultivation using varied injection of carbon dioxide and aeration. The treatments were control (K), 2000 cc CO2 injection and aeration (P1), 3000 cc CO2 injection and aeration (P2), 2000 cc CO2 injection without aeration (P3), and 3000 cc CO2 injection without aeration (P4). Samples weight were 3 gram in early cultivation on laboratorium scale for 42 days observation. The results showed that the daily growth rate Gelidium latifolium during the study ranged from 0.02-1.06%. The highest daily growth rate was 1.06±0.14% (P2). Carbohydrate yield was 18.23% in early cultivation then 19.40% (K and P2), 20.40% (P1), 16.87% (K3), and 16.40% (P4) after cultivation. The high of carbohydrates value may not guarantee the sustainable Gelidium latifolium biomass utilization as raw material for bioethanol production because of the low growth rate, thus it is necessary to modified and encourage cultivation method effectively.

Published: October 2017

Tuna is one of the important export commodities to increase government income. One of economically important tuna species is bigeye tuna (Thunnus obesus) which has a proportion of 21% of the total production of large tuna group. The objective of this study was to investigate the effects of different moon phase on the catch of bigeye tuna (T. obesus) in Eastern Indian Ocean. Data collection was conducted by the scientific observers from August 2005 to June 2014 in the tuna longline vessels were based in the port of Benoa, Bali. Moon phase data were collected from August 2005 to June 2014 from National Aeronautics and Space Administration (NASA). Catch data were calculated using the catch rate formula which defined as the number of catches per 100 hooks. The number of catch rate then was sorted into each moon phases and were analyzed using one-way Anova. This study covered 62 trips and 1,480 numbers of operations or sets was conducted from sampled vessels. The result showed that the average catch rate of bigeye tuna differed significantly among the moon phases. Tukey post-hoc tests showed that the average catch rate at full moon was the highest among the groups with around 0.3/100 hooks. This study showed that moon phase had significant effect on the catch of bigeye tuna (T. obesus) that increased the catch during full moon.

Published: October 2017

Acanthophyllia deshayesiana has a different habitat with Cynarina lacrymalis in the nature, but they have same character on living forms, diameter, and height of corallite. Both of these species are considered synonym, thus it needs verification study to describe whether it is synonym species or not based on morphological data. Eleven descriptive characters and seven morphometric characters were used to verify the synonym species of these coral. Descriptive data were performed by scoring method, while morphometric data were obtained from morphometric. Morphometric data were analyzed by Correspondence Analysis of Principal Coordinates (CAP) and Agglomerative Hierarchical Cluster (AHC), while descriptive data were analyzed by UPGMA (Unweight Pair Group Method with Arithmetic Mean). The result showed that both of these coral cannot differentiate based on morphometric measurement. It can differentiate significantly based on descriptive characters, so both of these coral are not synonym. Keywords: synonym, morphometric, descriptive, Cynarina lacrymalis, Acanthophyllia deshayesiana
Burrowing Time of the Three Indonesian Hippoid Crabs After Artificial Dislodgment
Authors: Wardiatno Yusli , Qonita Yuyun , Hakim Agus Alim
Published: October 2017

Three species of hippoid crabs are the target species of intertidal fishery along coastal line in District Cilacap, south Java; namely Emerita emeritus, Hippa adactyla and Albunea symmista. In Adipala sandy beach, Cilacap  an experiment was conducted to reveal the burrowing time and velocity of the crabs. The experiment was performed by removing the crabs from their burrows, measuring their carapace length, and releasing them immediately on the substrate. Burrowing time was measured from the start of burrowing to the disappearance of the entire carapace under the sediment surface. Among the three species, E. emeritus had the fastest burrowing time. As a consequence in terms of velocity, the burrowing velocity of Albunea symmista was higher than that of Hippa adactyla and Emerita emeritus; meaning that with the same size A. symmista needs longer time to burrow. By evaluating with other previous studies, the burrowing time and burrowing velocity of the three sand crabs were comparable. The ability of fast burrowing in the three species seems likely to be the advantage for their survival in large wave disturbed coarse sandy habitat and for their ability to widely exist along the sandy coast of south Java.

Published: October 2017

The pollutant quantity of heavy metals entering water environment does not give complete answer toward the generated effect and risk, however it needs thoroughly study related to the pollutant dynamic. The aim of this research was to investigate the fate of Pb and Zn in water, such as: distribution, behavior, and reactivity (case study: Jeneberang Estuary, Makassar). Pb and Zn concentrations were determined using Atomic Absorption Spectrophotometry (AAS). The distribution of dissolved Pb and Zn showed a pattern that the lowest concentration was in the fresh water (the river zone), whereas the highest concentration was in the salt water (the marine zone). The distribution pattern of particulate Pb and Zn showed that the highest concentration was in the fresh water (the river zone) and the salt water (the marine zone), whereas the lowest concentration was in the estuary zone. The behavior of dissolved Pb and Zn tended to increase the concentration (desorption) along the increased salinity gradient. The residual fraction was the dominant component of geochemical fractions in the sediment that indicated the sources of Pb and Zn mainly derived from a natural process and the reactivity was low in the water. Keywords: distribution, behavior, reactivity, lead, zinc, pollution

Culturally Contingent Electronic Word-of-Mouth Signaling and Screening: A Comparative Study of Product Reviews in the United States and Japan
Authors: Lin Hsin-Chen , Kalwani Manohar U.
Published: October 2017

Electronic word of mouth (eWOM) is an important source of influence on consumer decision making, yet little is known about cross-cultural differences in both the occurrence of eWOM and the relationship between eWOM and sales. The authors draw on signaling theory to develop a conceptual model and assess the relationships between country and the occurrence of eWOM, as well as between online ratings and relative product sales according to country. Online reviews and sales rank data for books, CDs, and DVDs were collected from Amazon U.S. and Amazon Japan in 2009 and 2017. Results suggest cross-national differences in both the occurrence of eWOM (eWOM signaling) and the relationship between eWOM and relative product sales (eWOM screening). These national differences appear to change over time: some remain stable, some disappear, and others emerge. The proposed culturally contingent signaling and screening model may be adopted as a framework for future research on cross-cultural eWOM. The results also inform the literature on cultural change by suggesting that cultural differences in eWOM change in nuanced patterns over time.
Frontline Problem-Solving Effectiveness: A Dynamic Analysis of Verbal and Nonverbal Cues
Authors: Marinova Detelina , Singh Sunil K. , Singh Jagdip
Published: October 2017

This study examines the impact of frontline employees' problem solving on customer satisfaction (CSAT) during ongoing interactions prompted by service failures and complaints. Using outsourced regulation theory, the authors predict negative moderating effects of frontline relational work and displayed affect on the dynamic influence of frontline solving work on CSAT. Frontline employees' verbal (nonverbal) cues provide the basis to identify solving and relational work (displayed affect). The authors test hypotheses with data from video recordings of real-life problem-solving interactions involving airline customers as well as a controlled experimental study. They find that frontline solving work has a positive effect on CSAT, and it increases in magnitude as the interaction unfolds. However, this positive effect becomes weaker for relatively higher levels of frontline relational work or displayed affect and, conversely, stronger for relatively lower levels over time. In summary, overdoing relational work and overdisplaying positive affect diminish the efficacy of problem-solving interactions, a finding that provides implications for theory and practice.
Solution of 2-D Inverse Heat Conduction Problem with Graphic Accelerator
Authors: Felde I. , Fried Z. , Szénási S.
Published: October 2017

The parallelized particle swarm optimization (PSO) method has been developed to solve inverse heat transfer problems. Temporal- and spatial-dependent heat transfer coefficient functions obtained on the surfaces of axis-symmetrical work pieces are estimated by applying the novel technique. The goal function to be minimized by the PSO approach is defined by the deviation of the measurements and the calculated temperatures. The PSO algorithm has been parallelized and implemented on a graphic processing unit (GPU) architecture. Numerical results demonstrate that the determination of heat transfer coefficient functions can be performed by using the parallelized PSO method as well as the GPU implementation and that they provide a less time-consuming and more accurate estimation.
Bayesian Inference for Correlations in the Presence of Measurement Error and Estimation Uncertainty
Authors: Matzke Dora , Ly Alexander , Selker Ravi , Weeda Wouter D. , Scheibehenne Benjamin , Lee Michael D. , Wagenmakers Eric-Jan
Published: October 2017

Whenever parameter estimates are uncertain or observations are contaminated by measurement error, the Pearson correlation coefficient can severely underestimate the true strength of an association. Various approaches exist for inferring the correlation in the presence of estimation uncertainty and measurement error, but none are routinely applied in psychological research. Here we focus on a Bayesian hierarchical model proposed by Behseta, Berdyyeva, Olson, and Kass (2009) that allows researchers to infer the underlying correlation between error-contaminated observations. We show that this approach may be also applied to obtain the underlying correlation between uncertain parameter estimates as well as the correlation between uncertain parameter estimates and noisy observations. We illustrate the Bayesian modeling of correlations with two empirical data sets; in each data set, we first infer the posterior distribution of the underlying correlation and then compute Bayes factors to quantify the evidence that the data provide for the presence of an association.

Green synthesis of pectin mediated hydroxyapatite nanoparticles from culinary banana bract and its characterization
Authors: Begum Y.A. , Deka S.C.
Published: October 2017

Green synthesis of hydroxyapatite (HA) nanoparticles was followed using various concentrations of pectin extracted from the culinary banana bract. The effect of pectin concentrations on purity, crystallinity, particle size, and morphology of synthesized HA nanoparticles were studied. The extracted pectin was characterized by proton-1 nuclear magnetic resonance spectroscopy (1H NMR) and Fourier transform infrared (FT-IR) spectroscopy. FT-IR results revealed that increased concentration (0–0.075 % w/w) of pectin substantially improved the purity level of synthesized HA nanoparticles. In addition, higher concentration of pectin also reduced the crystallinity and size of the synthesized HA nanoparticles, which was confirmed by X-ray diffraction (XRD) and SEM results, respectively. The synthesized HA nanoparticles at increased pectin concentration (HA0.075) evinced high purity, less crystallinity, and discrete uniform shape. Results of TEM images have the credence to reveal the presence of nanosized discrete particles (20–50 nm) with lattice structure of hydroxyapatite.
Probiotic biofilm on carrier surface: A novel promising application for food industry
Authors: Grossova M. , Rysavka P. , Marova I.
Published: October 2017

In this essay work, the ability of probiotic biofilm formation on carrier surface was demonstrated. Probiotic biofilms exhibit the same properties as pathogen microbial biofilms but with higher resistance to low pH values and bile salts. The ability of different probiotic strains (Lactobacillus acidophilus, Bifidobacterium breve, Bifidobacterium longum) to interact with pre-selected carriers divided into 3 categories (polymers, complex food matrices, and inorganic compounds) was tested. Lactobacillus acidophilus and Bifidobacterium longum combined with inorganic silica carrier exhibited the interaction leading to biofilm formation only. Prepared biofilm (Lactobacillus acidophilus) was then subjected to comparative study with planktonic bacterial culture. The ability to survive in the presence of low pH value (pH 1–3) and bile salts (0.3% solution) was evaluated. Low pH value (pH 1) had a harsh effect on free cell culture causing decreased cell viability (71.9±3.2% of viable cells). Biofilm culture exhibited higher resistance to low pH value, the viability exceeded 90%. The exposure of free cell probiotic culture to porcine bile resulted in an almost constant decrease in viability during the study period (68.2±1.1% of viable cells, after 240 min incubation). Viability of biofilm after the exposition to bile was almost constant with a slight decrease of no more than 5% during the study.

Published: October 2017

In the dairy industry different types of prebiotics, such galacto-oligosaccharide, lactulose, lactosucrose, tagatose, lactitol, lactobiono- and glucono-δ-lactone are synthesized through different chemical and biochemical reactions (hydrolysis, transgalactosylation, isomerization, fructosyl-transfer, reduction, and oxidation) as well as microbial fermentation processes using raw whey or isolated lactose as feedstock. Lactose-derived prebiotics have several functional and nutritional values. The biochemical activities of lactose-based prebiotics are expressed in the presence of probiotics (lactic acid bacteria, yeasts, Bacillus spp.). Galacto-oligosaccharide and lactosucrose reduce the risk of bowel disorder (diarrhea), inflammatory bowel disease (ulcerative colitis and crohn’s disease), and colon cancer. Galacto-oligosaccharide helps colonic absorption of minerals (iron, magnesium and calcium) and prevents osteoporosis. Lactulose, galacto-oligosaccharide, and lactitol promote laxative activity. Furthermore, lactulose may decrease the risk of hepatic encephalopathy. Prebiotics have low calorific value and glycemic index. Galacto-oligosaccharide and tagatose reduce the risks of hyperglycemia (Type 2 diabetes) and low density lipid (lipoprotein) accumulation in blood stream. Moreover, prebiotics improve immunomodulation, which reduces the risk of respiratory infection and allergies.

Background and aims

Recent technological developments have brought about notable changes in the way people gamble. The widespread use of mobile Internet devices and gambling websites has led to a significant leap in the number of people who recreationally gamble. However, for some, gambling can turn into a psychiatric disorder resembling substance addiction. At present, there is a shortage of studies examining differences between adults with gambling disorder (GD) who exclusively make sports bets online, GD patients that are non-sports Internet gamblers, and offline gamblers. Therefore, this study was undertaken to determine the differences between these three groups, considering sociodemographic, personality, and clinical characteristics.

Methods

The sample consisted of 2,743 treatment-seeking male patients from the Pathological Gambling Unit at a university hospital. All patients met DSM-5 criteria for GD.

Results

We found that gamblers who exclusively engaged in non-sports Internet gambling activities were younger than offline gamblers and online sports gamblers. Non-sports Internet gamblers were also more likely to have greater levels of debt compared with offline gamblers. In terms of personality characteristics, our sample displayed low levels of self-directedness and cooperativeness and high levels of novelty seeking. In addition, online sports gamblers obtained higher scores in persistence than non-sports Internet gamblers and offline gamblers.

Discussion and conclusion

Although differences if terms of gambling severity were not identified between groups, GD patients who exclusively bet online appear to possess distinct personality characteristics and higher debt levels compared with offline gamblers.
How coping styles, cognitive distortions, and attachment predict problem gambling among adolescents and young adults
Authors: Calado Filipa , Alexandre Joana , Griffiths Mark D.
Published: October 2017

Background and aims

Recent research suggests that youth problem gambling is associated with several factors, but little is known how these factors might influence or interact each other in predicting this behavior. Consequently, this is the first study to examine the mediation effect of coping styles in the relationship between attachment to parental figures and problem gambling.

Methods

A total of 988 adolescents and emerging adults were recruited to participate. The first set of analyses tested the adequacy of a model comprising biological, cognitive, and family variables in predicting youth problem gambling. The second set of analyses explored the relationship between family and individual variables in problem gambling behavior.

Results

The results of the first set of analyses demonstrated that the individual factors of gender, cognitive distortions, and coping styles showed a significant predictive effect on youth problematic gambling, and the family factors of attachment and family structure did not reveal a significant influence on this behavior. The results of the second set of analyses demonstrated that the attachment dimension of angry distress exerted a more indirect influence on problematic gambling, through emotion-focused coping style.

Discussion

This study revealed that some family variables can have a more indirect effect on youth gambling behavior and provided some insights in how some factors interact in predicting problem gambling.

Conclusion

These findings suggest that youth gambling is a multifaceted phenomenon, and that the indirect effects of family variables are important in estimating the complex social forces that might inﬂuence adolescent decisions to gamble.

У раціоні людей різних вікових груп  молочні продукти традиційно займають суттєву частку. Особливо користуються попитом кисломолочні продукти. Технології виробництва резервуарним способом передбачають механічне оброблення кисломолочного згустку, а термізованих продуктів - термомеханічне, в результаті чого  може порушуватися структура продукту, відбутися відділення сироватки та розшарування готового продукту. Для запобігання появі недоліків консистенції широко використовують стабілізатори структури. Переважна більшість стабілізаторів, що виконують функції загущувачів та гелеутворювачів, за своєю природою – гідрофільні речовини, які завдяки зв’язуванню вільної вологи та підвищенню в’язкості сумішей, забезпечують утворення необхідної структури. Для продуктів переробки зернових культур такі властивості обумовлені, в першу чергу, наявністю  вуглеводів, в меншій мірі – білками та баластними речовинами. Сучасні технології переробки зернових дозволяють одержувати інгредієнти і  продукти, які можуть використовуватися в якості структуроутворювачів під час виробництва молочних продуктів з комбінованим складом сировини.  Проведено аналіз структуроутворювачів, зокрема, желатину, агару, альгінату натрію, модифікованого крохмалю, рисового борошна, пшеничного та кукурудзяного зернопродуктів  для виробництва кисломолочних продуктів. Основними критеріями відбору структуроутворювачів були діапазон температур, за яких стабілізатори виявляли свої гелеутворювальні властивості, вологоутримувальна здатність, в’язкість, здатність до утворення однорідної суміші під час зберігання кисломолочних продуктів. Опрацьовано способи застосування рисового борошна за температури пастеризації сумішей (82±2)0С для кисломолочних напоїв, пшеничного та кукурудзяного зернопродуктів за температури термізації сумішей (74±2)0С для термізованих сиркових виробів. Обґрунтовано використання продуктів переробки зернових, які покращують органолептичні та реологічні показники готового продукту. Розроблено технологічну схему та визначено режими технологічних операцій під час виробництва молочних продуктів з комбінованим складом сировини.
REPRESENTACIÓN SEMIÓTICA DE LA NOCIÓN DE FUNCIÓN: CONCEPCIONES DE LOS ESTUDIANTES QUE TRANSITAN DEL COLEGIO A LA UNIVERSIDAD - Semiotic Representation of the notion of function: Conceptions of Students who pass from High School to College
Authors: Prada Núñez Raúl , Hernández-Suárez César Augusto , Jaimes Contreras Luis Alberto
Published: October 2017

Este artículo constituye el reporte de una investigación mayor, cuyo objetivo es evaluar los cambios o modificaciones en la habilidad de los estudiantes para articular diversos registros de representación semiótica con relación a la noción de función en estudiantes matriculados en la asignatura Cálculo Diferencial de dos programas de ingeniería de una universidad pública. La investigación toma como marco de referencia la articulación de los trabajos de diversos investigadores, especialmente los de Duval y Hitt. La metodología utilizada es de tipo cuantitativo y es de naturaleza descriptiva. Los datos fueron recolectados mediante un test de ocho ítems, en los que se utilizan diversos registros de representación en torno al concepto de función. Este test se aplicó al inicio del experimento; luego, se practicó una intervención pedagógica en relación con el concepto de función fundamentada en la articulación de los diversos registros de representación semiótica, luego de lo cual se practicó una nueva aplicación del test. En los resultados se muestran las concepciones observadas entre los estudiantes en dos momentos diferentes del semestre por comparación de los datos obtenidos tanto en el pretest como en el postest. La noción de función que poseen los estudiantes no se corresponde con una definición formal; en su lugar, manifiestan una serie de variaciones conceptuales que, en algunos casos, se encuentran más próximas a una noción intuitiva.

Background

Genomic fusions of the anaplastic lymphoma kinase gene (ALK) are a well-established therapy target in non-small cell lung cancer (NSCLC). From a survey of 114,200 clinical cases, we determined the prevalence of ALK rearrangements (rALK) in non-NSCLC tumors and report their responsiveness to therapies targeting ALK.

Materials and Methods

Comprehensive genomic profiling of 114,200 relapsed and metastatic malignancies, including both solid tumors and hematolymphoid cancers, was performed using a hybrid-capture, adaptor ligation-based next-generation sequencing assay.

Results

Of 114,200 clinical samples, 21,522 (18.8%) were NSCLC and 92,678 (81.2%) were other tumor types. Of the 876 (0.8%) cases with ALK fusions (fALK) or rALK, 675 (77.1%) were NSCLC and 201 (22.9%) were other tumor types. ALK fusions were significantly more frequent in NSCLC (3.1%) than non-NSCLC (0.2%; p < .0001). Patients with non-NSCLC tumors harboring fALK were significantly younger (p < .0001) and more often female (p < .0001) than patients with fALK-positive NSCLC. EML4 was more often the fusion partner in NSCLC (83.5%) versus non-NSCLC tumors (30.9%; p < .0001).

Conclusion

ALK rearrangements can be identified in a wide variety of epithelial and mesenchymal malignancies beyond NSCLC. Anti-ALK therapies can be effective in non-NSCLC tumors driven by fALK, and further study of therapies targeting ALK in clinical trials involving a wider variety of cancer types appears warranted.
Estimating column diameters in jet-grouting processes
Authors: Kimpritis Thomas , Standing Jamie R. , Thurner Robert
Published: October 2017

Jet grouting is widely used in geotechnical engineering for a variety of applications and is a well-proven technique. As with many techniques developed from a practical perspective, there is still scope for improvements both in construction practice and design. This paper focuses on one of the most crucial elements of quality control required with jet-grouting operations, the diameter of the constructed column. First, the jet-grouting method is explained and the main issues of the concept are highlighted. A description follows of the techniques available for estimating column diameter, discussing their application and evaluation on site. There is a particular emphasis on two methods: inclined core drilling and a newly developed thermic approach, both of which were implemented on two construction projects. Data from these case studies are reported and analysed extensively, in conjunction with influencing factors such as the ground conditions, to assess their effects on the achieved diameter. An empirical approach for evaluating the diameter of jet-grouted columns is presented, based on various factors influencing their size such as monitor lifting speed and soil strength.

Impact of shear connectors on the behaviours of box-girders with corrugated webs
Authors: Lu Yanqiu , An Guanfeng
Published: October 2017

The impact of different shear connectors (perfobond leisten (PBL) shear connectors and stud shear connectors) on the mechanical performances of prestressed concrete (PSC) composite box-girders with corrugated steel webs was studied. Mechanical properties were researched by conducting experiments on two specimens with PBL shear connectors or stud shear connectors; these properties included the ultimate bearing capacity, the flexural stiffness, crack resistance and the efficiency of prestressing of the girder. The test results showed that, compared with the stud shear connectors, PBL shear connectors greatly improved the ultimate bearing capacity, flexural stiffness and crack resistance of PSC composite box-girders with corrugated steel webs. However, regarding the efficiency of prestressing, the PBL shear connectors did not perform as well as the stud shear connectors.
