Identifying and Structuring the Objectives of the Islamic State of Iraq and the Levant (ISIL) and Its Followers
Authors: Siebert Johannes , von Winterfeldt Detlof , John Richard S.
Published: November 2015

This study addresses three questions:

What are the objectives of the leaders of ISIL? What are the objectives of the followers of ISIL? How are the two sets of objectives related?

To answer these questions, we analyzed the transcripts of interviews and presentations of 59 subject matter experts (SMEs) and conducted a separate analysis of speeches of ISIL leaders and selected Internet sources. In both efforts we identified and structured the strategic, fundamental, and means objectives of ISIL and its followers. The results indicate that ISIL’s leaders pursue four strategic objectives: (1) Establish a Caliphate in Iraq and the Levant, (2) Control and Govern the Caliphate, (3) Expand Islam and Sharia Law Worldwide, and (4) Recreate the Power and Glory of (Sunni) Islam. The followers’ objectives can be partitioned into three strategic objectives: Humanitarian Fulfillment, Religious Fulfillment, and Personal Fulfillment. The objectives identified from the SME interviews were similar to those identified from ISIL leaders’ statements and the Internet. However, the Internet search revealed many more personal objectives of ISIL followers. The results further indicate that ISIL’s leadership objectives are closely aligned with those of its followers. There also is a sharp contrast between the objectives of ISIL and those of Al Qaeda, particularly ISIL’s emphasis on occupying and controlling territories in Iraq and Syria versus Al Qaeda’s focus on worldwide jihad.
Constrained Resource Assignments: Fast Algorithms and Applications in Wireless Networks
Authors: Berger André , Gross James , Harks Tobias , Tenbusch Simon
Published: November 2015

Resource assignment problems occur in a vast variety of applications, from scheduling problems over image recognition to communication networks. Often these problems can be modeled by a maximum weight matching problem in (bipartite) graphs or generalizations thereof, and efficient and practical algorithms are known for these problems. Although in some of the applications an assignment of the resources may be needed only once, in many of these applications, the assignment has to be computed more often for different scenarios. In that case it is often essential that the assignments can be computed very fast. Moreover, implementing different assignments in different scenarios may come with a certain cost for the reconfiguration of the system. In this paper, we consider the problem of determining optimal assignments sequentially over a given time horizon, where consecutive assignments are coupled by constraints that control the cost of reconfiguration. We develop fast approximation and online algorithms for this problem with provable approximation guarantees and competitive ratios. Moreover, we present an extensive computational study about the applicability of our model and our algorithms in the context of orthogonal frequency division multiple access (OFDMA) wireless networks, finding a significant performance improvement for the total bandwidth of the system using our algorithms. For this application (the downlink of an OFDMA wireless cell) , the run time of matching algorithms is extremely important, having an acceptable range of a few milliseconds only. For the considered realistic instances, our algorithms perform extremely well: the solution quality is, on average, within a factor of 0.8–0.9 of optimal off-line solutions, and the running times are at most 5 ms per phase even in the worst case. Thus, our algorithms are well suited to be applied in the context of OFDMA systems.

Update on the role of cryptosporidiosis in calf diarrhoea
Authors: Hotchkiss Emily , Thomson Sarah , Wells Beth , Innes Elisabeth , Katzer Frank
Published: November 2015

The protozoan parasite Cryptosporidium parvum is increasingly being recognised as the primary cause of diarrhoea in young calves in the UK, with peak prevalence of clinical disease and intensity of oocyst shedding at 1 to 3 weeks of age. There are limited safe and effective therapeutic options that specifically treat, or prevent, cryptosporidiosis. Control on farms should be directed towards management strategies that minimise within- and between-farm transmission of the parasite. These include regular, appropriate disinfection and hygiene measures to reduce contamination of the environment and optimising calf health by a proactive approach to colostrum management and control of other enteropathogens.
Animal health and disease monitoring in the abattoir
Authors: van Klink Ed G.M. , Prestmo Pia Gjertsen , Grist Andrew
Published: November 2015

All slaughter animals are examined before and after slaughter by an Official Veterinarian. Findings of diseases and conditions that could affect public health or animal health have to be reported to the management of the abattoir and the private veterinarian as well as the farmer of the farm of origin. The abattoir provides a vast amount of information on zoonotic and notifiable diseases, as well as diseases relevant for animal husbandry or on-farm animal health. Notifiable diseases can be identified through clinical signs (e.g. foot-and-mouth disease), but in specific cases samples are taken for serological surveillance (e.g. Aujeszky's disease). Surveillance and monitoring schemes are generally based on the Terrestrial Animal Health Code of the World Organisation for Animal Health. Bovine tuberculosis is another example of a disease for which monitoring and surveillance is often entirely based on abattoir detection. For transmissible spongiform encephalopathies (TSEs) abattoir sampling constitutes an important proportion of all samples taken. Monitoring of public health threats, including diseases such as trichinellosis and cysticercosis, remains an important element of the inspection practices in the abattoir. Monitoring of trichinellosis can be risk based: only pigs expected to be at a higher risk of infection are included in the testing regimen. Abattoir sampling is also used for assessment of compliance with legislation on residues of antimicrobial drugs in meat. The number of samples is small, but the sampling itself has a preventive effect. An important category of diseases are those relevant for the performance on farm. Some examples are lung and heart lesions, as well as several parasitic diseases such as liver fluke. Indicators for welfare problems on-farm may also appear at slaughter. Foot lesions in poultry and tail biting in pigs are some examples. Abattoir information is easy and cheap to come by and is underutilised at the moment, particularly to feed into animal health management on farm. It would be advisable to design a feedback system in which post-mortem findings are described with the interest of the farmer and her/his veterinary surgeon in mind.

Bayesian estimation of the parameters of the bivariate generalized exponential distribution using accelerated life testing under censoring data
Authors: M. P Abd El-Maseh,
Published: November 2015

In this paper, the Bayesian estimation for the unknown parameters for the bivariate generalized exponential (BVGE) distribution under Bivariate censoring type-I samples with constant stress accelerated life testing (CSALT) are discussed. The scale parameter of the lifetime distribution at constant stress levels is assumed to be an inverse power law function of the stress level. The parameters are estimated by Bayesian approach using Markov Chain Monte Carlo (MCMC) method based on Gibbs sampling. Then, the numerical studies are introduced to illustrate the approach study using samples which have been generated from the BVGE distribution.
The relationship between attitudes towards menarche and current attitudes towards menstruation of women: A comparative study
Authors: Erbil Nülüfer , Felek Neslihan , Karakaşlı Ebru
Published: November 2015

Purpose: The study was conducted to determine affecting factors and to investigate relationship  between  attitudes towards menarche and current attitudes towards menstruation of women and to compare characteristics of menarche and menstruation of women who were born and raised in the northeastern and western of Turkey. 

Method and Materials: This descriptive and comparative study was participated totally 400 volunteer women. The data were collected using a questionnaire containing defined closed and open-ended questions.

Results: The study results showed that women living in Ordu province than women living in Aydın province expressed positive attitudes toward menarche, and the difference was found significant. Nevertheless, attitudes towards current menstruation were similar in both provinces. When the data of 400 women were evaluated together; women’s attitudes towards menarche were compared with the current attitudes towards menstruation, and the difference was found statistically significant. Although attitudes of the women towards menarche varied according to where they lived, their current attitudes towards menstruation were similar. In addition, depending upon the province, there were statistically significant differences in women’s age at menarche, recollection of menarche, and feelings of shame or happiness at menarche, source and adequacy of information about menstruation, and regularity of their menstrual cycle.  

Conclusions: Early menstrual experiences may be related to menstrual experiences later in life and women’s attitudes towards menstruation were not affected by geographical locations. In order to develop positive attitudes towards menarche and a woman’s future years of menstrual cycles, it is very important that accurate and adequate information for young girls be provided before menarche. 
Avaliação da influência da adição de fibras de aço no concreto fluido solicitado por tensões de tração
Authors: Góis Fernanda Alves Pinto , Barboza Aline Da Silva Ramos
Published: November 2015

O desenvolvimento de novas tecnologias na produção do concreto ao longo do tempo vêm permitindo elevar a sua resistência à compressão, melhorar a trabalhabilidade e garantir maior durabilidade. Apesar de suas muitas vantagens e melhorias atingidas, o concreto apresenta limitações relacionadas ao seu comportamento frágil quando na presença de esforços de tração. Uma alternativa para contornar este problema é a utilização de armadura dispersa por meio de fibras no concreto, obtendo-se assim um material compósito que possui características diferentes do material original. Buscando colaborar na avaliação da eficiência da adição de fibras, o presente trabalho analisa o comportamento de concretos fluidos reforçados com fibras de aço, submetidos a tensões de tração, considerando como parâmetros de influência o fator de forma e a fração volumétrica. Para isso, foram utilizados corpos-de-prova cilíndricos de dimensões de 10 cm x 20 cm de concreto fluido de resistência usual, com teor de fibras de aço de 0,4% e 0,8%  da quantidade de cimento em  massa e com fatores de forma de 33, 50 e 80. Os corpos de prova foram submetidos a ensaios de tração por compressão diametral. Com os resultados obtidos foi possível afirmar que a matriz cimentícia fluida, com adição de fibras com maior fator de forma e maior fração volumétrica tendem a ser mais eficientes na presença de esforços de tração.
Avaliação da estabilidade de estocagem de ligante asfáltico modificado com blenda de borra oleosa de petróleo e borracha de pneus

Published: November 2015

O desenvolvimento de novas tecnologias para minimizar os efeitos da ação de variações climáticas e da alta densidade de tráfego em pavimento rodoviários vem sendo pesquisado nos últimos anos empregando macromoléculas e aditivos modificadores de ligante asfáltico na busca de misturas asfálticas de alto desempenho. O objetivo deste trabalho foi utilizar borra oleosa de fundo de tanque, oriunda de unidade de tratamento primário de petróleo, um passivo de difícil disposição no ambiente, como agente de modificação de cimento asfáltico de petróleo, CAP 50/70, e avaliar a estabilidade de estocagem do ligante modificado quanto à separação de fase por meio de análise térmica e reológica. Devido à difícil dispersão da borra oleosa de petróleo no CAP 50/70, blenda de borracha de pneus inservíveis com borra oleosa de petróleo, na proporção 15/85% em massa foi preparada e utilizada como agente modificador, na quantidade de 10% em massa. Os resultados obtidos mostram que o referido ligante modificado atende às especificações brasileiras, no que se refere à temperatura de usinagem e compactação de misturas do tipo CAUQ, empregadas em revestimentos de pavimento rodoviário. Contudo, há separação de fase no ligante modificado na concentração dos modificadores estudados, tornando necessários estudos complementares sobre estabilidade de estocagem.

Published: November 2015

O setor rodoviário representa o maior meio de transporte utilizado no Brasil, tanto para pessoas como para cargas. As modificações, nas últimas décadas, de cargas máximas e materiais utilizados em pavimentos rodoviários, torna necessário um estudo mecânico dessas estruturas para garantir sua durabilidade. A determinação do módulo de resiliência destes materiais (necessários nos estudos mecânicos) pode ser realizada por meio de ensaios laboratoriais ou por retroanálise de bacias deflectométricas obtidas em ensaios não destrutivos de campo. Assim, diversos programas computacionais podem ser utilizados para calcular as tensões, deformações e deslocamentos que ocorrem na estrutura com a aplicação de cargas. São exemplos destes programas o EverStress 5.0 e o EFin3D, baseados nos Métodos das Camadas Finitas e dos Elementos Finitos, respectivamente. Neste trabalho, realizou-se um estudo comparativo de características elásticas obtidas em laboratório e em campo, sobretudo para estabelecer as diferenças na extrapolação de escalas. Este estudo foi realizado para uma seção de pavimento existente na BR-101/SE, construída com revestimento com ligante modificado por SBS e base de BGTC, para o qual foi avaliado o efeito destas diferenças em termo de tensões, deformações e deslocamentos calculados para cada situação. Pôde-se observar uma variabilidade importante de comportamento da estrutura em campo, principalmente de camada de BGTC e a subjacente a ela. A camada de revestimento também se comportou diferente na comparação campo-laboratório.
Stress Testing International Financial Reporting Standards (IFRS): Accounting for Stability and the Public Good in a Financialized World
Authors: Haslam Colin , Tsitsianis Nick , Hoinaru Razvan , Andersson Tord , Katechos George
Published: November 2015

The recent Maystadt report (2013) challenged the European Parliament to modify governance arrangements surrounding the design and endorsement of international financial reporting standards (IFRS) issued by the International Accounting Standards Board (IASB). In addition the Maystadt report constructs an argument that accounting information has the capacity to also modify behaviour and that this might not be conducive for the European public good, financial stability and economic development. In this paper we argue that IFRS need to be stress tested for their impact on firm-level financial stability in a financialized world. The financialized firm can revalue a range of assets to their market value crystalizing future earnings into current values but these valuations can become impaired. Asset value impairments will be charged to shareholder equity but this is being hollowed out because a higher proportion of earnings are being distributed to shareholders. Accounting disclosures are not only an information feed to users they inform the stewardship and control of a firm’s resources and in the financialized firm the potential for financial instability is heightened and this can translate into a moral hazard for society.
“Why Polarized Trust Matters”
Authors: Hetherington Marc
Published: November 2015

The early 2000s has witnessed the rise of a new phenomenon in public opinion, polarized political trust. By polarized, I mean that those who identify with the party opposite the president express much less trust in government than those who identify with the president’s party. Indeed, outparty partisans express almost no political trust at all. This is important because it is this group of people who have traditionally been the bridge that allows for consensus building in the electorate. Consensus in the electorate, in turn, encourages cooperation across party lines in Congress. Without consensus but with deep distrust of the other party, office holders from the party opposite the president have no incentive to rise above their worst partisan instincts because partisans from their side will tend to blame the president’s party for resultant problems of governance.
Self-concept and social comparison and their relation with smoking and alcohol consumption in adolescents
Authors: Özdemir Aysel , Koçoğlu Gülay
Published: November 2015

Background:

Some attitudes that possess certain risks such as smoking and alcohol consumption rate are increasing among the adolescent age group. For this reason it is very important to shape the attitudes of adolescents during their growth period.

Objective:

The aim of this study is to investigate the association of social comparison and self-concept of adolescents’ relation with smoking and alcohol consumption.

Subjects:

Study was conducted as a prospective study in nine high schools which are located in city of Bursa, Turkey. Nine hundred and fifty-three (n=953) students were included.

Methods:

Data were gathered using a questionnaire form especially developed by researchers for this study according to relevant literature. For social comparison and self-concept evaluation Piers-Harris Self Concept Scale and Social Comparison Scale of Gilbert were used.

Results:

The mean age was 15.74±1.27 and 411 of cases (43.1%) were male. It was determined that smoking and alcohol consumption increased as the age of adolescents’ age increases. Rate of smoking and alcohol consumption was significantly higher in males compared to females. The mean self-concept scale score of the cases who smoke (52.30±11.01) were found to be lower than the non-smokers (56.07±10.13). The mean social comparison scale score of smoking adolescents’ (70.25±23.99) was higher than the non-smokers (69.43±25.47).

Conclusion:

The social comparison scale scores were found to be higher in adolescents who consume alcohol and smoke tobacco. In contrast to this result self-concept scale scores were low. As a conclusion this study reveals that attitudes such as smoking and alcohol consumption are mostly influenced by self-concept of the adolescents and family attitudes towards adolescents.
Parental alienation: the impact on men’s mental health
Authors: Sher Leo
Published: November 2015

Parental alienation is defined as a mental state in which a child, usually one whose parents are engaged in a high-conflict separation or divorce, allies himself strongly with one parent (the preferred parent) and rejects a relationship with the other parent (the alienated parent) without legitimate justification. Parental alienation may affect men’s mental health: a) parental alienation negatively influences mental health of male children and adolescents who are victims of parental alienation. Alienated children/adolescents display guilt, sadness, and depressed mood; low self-esteem and lack of self-confidence; distress and frustration; lack of impulse control, substance abuse and delinquent behavior; separation anxiety, fears and phobias; hypochondria and increased tendency to develop psychosomatic illness; suicidal ideation and suicide attempt; sleep and eating disorders; educational problems; enuresis and encopresis; b) parental alienation negatively affects the mental health of adult men who were victims of parental alienation when they were children and/or adolescents. Long-term effects of parental alienation include low self-esteem, depression, drug/alcohol abuse, lack of trust, alienation from own children, divorce, problems with identity and not having a sense of belonging or roots, choosing not to have children to avoid being rejected by them, low achievement, anger and bitterness over the time lost with the alienated parent; c) parental alienation negatively influences mental health of men who are alienated from their children. Fathers who have lost some or all contact with their children for months or years following separation or divorce may be depressed and suicidal.
A Semiparametric Bayesian Approach for Analyzing Longitudinal Data from Multiple Related Groups
Authors: Das Kiranmoy , Afriyie Prince , Spirko Lauren
Published: November 2015

Often the biological and/or clinical experiments result in longitudinal data from multiple related groups. The analysis of such data is quite challenging due to the fact that groups might have shared information on the mean and/or covariance functions. In this article, we consider a Bayesian semiparametric approach of modeling the mean trajectories for longitudinal response coming from multiple related groups. We consider matrix stick-breaking process priors on the group mean parameters which allows information sharing on the mean trajectories across the groups. Simulation studies are performed to demonstrate the effectiveness of the proposed approach compared to the more traditional approaches. We analyze data from a one-year follow-up of nutrition education for hypercholesterolemic children with three different treatments where the children are from different age-groups. Our analysis provides more clinically useful information than the previous analysis of the same dataset. The proposed approach will be a very powerful tool for analyzing data from clinical trials and other medical experiments.
A review of adolescent prevention and positive youth development programs in non-English speaking European countries
Authors: Busiol Diego , Shek Daniel T.L. , Lee Tak Yan
Published: November 2015

In this paper, adolescent prevention and positive youth development programs in non-English speaking European countries are reviewed. A survey of the literature published in English, Italian, German, French, and Spanish language between 1994 and 2014 reported a total of 61 programs which have been evaluated by studies using quasi- or true experimental designs. Several observations are highlighted from this review. First, prevention programs outnumber positive youth development programs in Europe. Second, some countries spend significantly more effort and financial support on preventive programs than others. Third, some countries/regions deal with some specific adolescent problems more than other regions. Fourth, there are variations in the use of international standards for implementing and assessing programs as well as disseminating results. Finally, while most of the existing school-based programs are conducted at the local level, there are very few cross-country projects.
Amitriptyline and phenytoin prevents memory deficit in sciatic nerve ligation model of neuropathic pain
Authors: Abdulmajeed Wahab Imam , Ibrahim Ridwan Babatunde , Ishola Azeez Olakunle , Balogun Wasiu Gbolahan , Cobham Ansa Emmanuel , Amin Abdulbasit
Published: November 2015

Background: Phenytoin and amitriptyline are often reported to attenuate pain in chronic conditions. Information on their ability to ameliorate cognitive impairment associated with neuropathic pain remains unclear due to mixed results from studies. This study investigated the effects of phenytoin and amitriptyline on memory deficit associated with neuropathic pain.

Methods: Twenty-eight adult male Wistar rats were randomly divided into four groups: A, B, C, and D (n=7). Groups A, B, C, and D served as sham control, sciatic nerve ligated untreated, sciatic nerve ligated receiving amitriptyline (5 mg/kg), and sciatic nerve ligated receiving phenytoin (10 mg/kg) respectively. Treatments lasted for 14 days, after which both ‘Y’ maze and novel object recognition test (NOR) were performed. On the last day of treatment, the animals were anesthetized and their brain excised, and the prefrontal cortices and sciatic nerve were processed histologically using hematoxylin and eosin.

Results: There was memory impairment in the sciatic nerve ligated untreated group which was statistically significant (p<0.05) when compared to the phenytoin-treated, amitriptyline-treated, and sham control groups using the ‘Y’ maze and NOR tests. Histological quantification showed that the prefrontal cortices of the ligated animals showed increased neural population in comparison to normal control. These increases were significantly marked in the untreated ligated group. Sciatic nerve of untreated ligated group showed high demyelination and axonal degeneration which was ameliorated in the treated animals.

Conclusions: The administration of amitriptyline and phenytoin can ameliorate neuronal injury, demyelination, and memory impairment associated with neuropathic pain in Wistar rats.

Comparative assessment of five clinical Klebsiella isolates in terms of antibiotic resistance and plasmid profiles / Beş farklı klinik Klebsiella türünün antibiyotik dirençliliği ile plazmid profillerinin karşılaştırmalı olarak değerlendirilmesi
Authors: Avcıoğlu Nermin Hande , Bilkay Işıl Seyis
Published: November 2015

Objective: This study is firstly aimed to biotype and to investigate the antibiotic resistance profiles of Klebsiella strains which were isolated from clinical materials. Also plasmid profile types of Klebsiella species were investigated and the results were compared with each other.

Methods: Klebsiella strains were biotyped by BBL Enterotube II and the antibiotic resistance was tested by Kirby Bauer disc diffusion method. In order to analyse Klebsiella strains genotypically, plasmid DNA’s of them were isolated and generated plasmid profile types determined by Dice coefficients of similarity.

Results: According to biotyping, Klebsiella strains were distributed to five different species (K. pneumoniae, K. ornithinolytica, K. oxytoca, K. terrigena, K. rhinoscleromatis). As well as K. pneumoniae (37.33%) was the most isolated strain, K. terrigena (8.95%) which is not found to be investigated as much as other strains in the literature, was also observed. Additionally, it is determined that Klebsiella strains were resistant to at least one and at most seven antibiotics. With a similarity coefficient of 84%, it was observed that five different Klebsiella species displayed 17 different plasmid profile types. Among these profiles, P1 (52.23%) was the most observed type which exhibits >10 kbp plasmid DNA band and this profile was isolated from all strains.

Conclusion: Finally, it is observed that antibiotic resistance can be due to the plasmid or chromosomal sources and different strains of the same genus may exhibit the same plasmid profile because of the plasmid transformation from one strain to another.
Comparison of total phenolic contents and antioxidant capacities in mint genotypes used as spices / Baharat olarak kullanılan nane genotiplerinin toplam fenolik içerikleri ve antioksidan kapasitelerinin karşılaştırılması
Authors: Elmastaş Mahfuz , Telci İsa , Akşit Hüseyin , Erenler Ramazan
Published: November 2015

Objective: Mint (Mentha spp.) genotypes used as spices are cultivated in Turkey and used for different purposes including herbal tea, spices, the cosmetics industry, and are used in folk medicine. While mint species have been used in traditional practices during humanity’s long history, there is limited research on the comparison of their antioxidant capacity and phenolic contents. This aim of the research is to compare antioxidant capacity and phenolic contents in mint clones to determine superior genotypes for herbal and spice usage and cultivation.

Methods: Antioxidant capacity was evaluated by ferric reducing antioxidant power (FRAP) and trolox equivalent antioxidant capacity (TEAC). Total phenolic content in clones were determined by Folin-Ciocalteu method.

Results: Maximum total phenolic content [28.27±3.95 μg gallic acid equivalent (GAE)/g dry weight (DW)] and FRAP activity 577.09±46.02 μmol Trolox equiv/g DW were obtained from Clone 13 (M. spicata), while M. piperita clones were higher for TEAC activity (800.02±1.10 μmol Trolox equiv/g DW). The results were first records for M. villoso nervata. FRAP and TEAC activities selected clones were correlated with total phenolic content (r=0.77; 0.73 respectively).

Conclusion: According to the results, it can be suggested that Clone 13, Clone 5, (M. spicata) Clone 3 and Clone 8 (M. piperita) are more suitable for use as spice, herbal tea, and antioxidant agents. The clones must be selected for commercial cultivation by the grower and they can be used as spices and herbal teas.
Preserving Heritage, Fostering Change
Authors: Katz Mark , VanderHamm David
Published: November 2015

This article explores how two groups of American popular musicians have engaged with sound reproduction technologies—country artists and radio in the 1920s–40s and hip-hop DJs and video since 2000—to create an unintended but lasting cultural heritage for their musical traditions. Neither the radio broadcasts made by country artists nor the amateur videos of DJs were intended to be permanent. We argue that the practitioners of these traditions have acted as accidental archivists—shaping the development of their respective genres in the process of preserving them—and suggest how these archives may be of use to public historians.

Published: November 2015

With increasing interest in the representation of histories of mental health in museums, sound has played a key role as a tool to access a range of voices. This essay discusses how sound can be used to give voice to those previously silenced. The focus is on the use of sound recording in the history of mental health care, and the archival sources left behind for potential reuse. Exhibition strategies explored include the use of sound to interrogate established narratives, to interrupt associations visitors make when viewing the material culture of mental health, and to foster empathic listening among audiences.

DNA double-strand breaks (DSBs) represent one of the most threatening lesions to the integrity of genomes. In yeast Saccharomyces cerevisiae, NuA4, a histone acetylation complex, is recruited to DSBs, wherein it acetylates histones H2A and H4, presumably relaxing the chromatin and allowing access to repair proteins. Two subunits of NuA4, Yng2 and Eaf3, can interact in vitro with methylated H3K4 and H3K36 via their plant homeodomain (PHD) and chromodomain. However, the roles of the two domains and how they interact in a combinatorial fashion are still poorly characterized. In this study, we generated mutations in the PHD and chromodomain that disrupt their interaction with methylated H3K4 and H3K36. We demonstrate that the combined mutations in both the PHD and chromodomain impair the NuA4 recruitment, reduce H4K12 acetylation at the DSB site, and confer sensitivity to bleomycin that induces DSBs. In addition, the double mutant cells are defective in DSB repair as judged by Southern blot and exhibit prolonged activation of phospho-S129 of H2A. Cells harboring the H3K4R, H3K4R, K36R, or set1Δ set2Δ mutant that disrupts H3K4 and H3K36 methylation also show very similar phenotypes to the PHD and chromodomain double mutant. Our results suggest that multivalent interactions between the PHD, chromodomain, and methylated H3K4 and H3K36 act in a combinatorial manner to recruit NuA4 and regulate the NuA4 activity at the DSB site.
CACERÍA DE SUBSISTENCIA DE MAMÍFEROS EN EL SECTOR ORIENTAL DE LA RESERVA DE BIÓSFERA EL TUPARRO – VICHADA

Published: November 2015

RESUMEN

La cacería de subsistencia ha sido una actividad de vital importancia para las comunidades indígenas como fuente de proteína y venta. Se caracterizó la cacería de subsistencia realizada por comunidades de las etnias Piaroa y Curripaco presentes en la Reserva de Biosfera el Tuparro, por medio de registros de caza durante nueve meses de estudio. Se encontró que no hay diferencias significativas en cuanto a especies y número de individuos cazados entre las dos etnias, siendo Artiodactyla y Rodentia los órdenes con mayor aporte respecto al número de individuos, biomasa y riqueza de especies, lo cual fue similar a otros estudios realizados en el Neotrópico. Los Piaroa cazan más frecuentemente cuando los estudiantes llegan de la ciudad al resguardo, mientras que los Curripaco lo hacen para las reuniones evangélicas. El arte de caza más usado por las comunidades de las dos etnias fue la escopeta. Las etnias estudiadas tienen sus zonas de caza en la Reserva de Biósfera El Tuparro, y en ellas, los Curripaco están aprovechando directamente los recursos de su zona núcleo del Parque Nacional Natural El Tuparro.

ABSTRACT

Subsistence hunting has been an activity of vital importance to indigenous communities as a source of protein and sale. We characterized subsistence hunting by Curripaco and Piaroa ethnic groups present in the Tuparro Biosphere Reserve, through hunting records over nine months of study. We found no significant differences in species and number of individuals hunted by the two ethnic groups. The orders Rodentia and Artiodactyla contributed the most in terms of number of individuals, biomass and species richness, which was similar to studies to the Neotropics. The Piaroa hunt more frequently when students return to the community lands from the city, while the Curripaco do so for religious gatherings. The hunting method used most often by both ethnic groups was the shotgun. The hunting areas used by ethnic groups are within the RBT, and the Curripaco are utilizing the resources of the Tuparro Natural National Park, the core area.

Demostramos la existencia y ortogonalidad de operadores de onda naturalmente asociados a un Laplaciano compatible sobre una variedad completa con una esquina de codimensión 2. De hecho, probamos su completitud asintótica, es decir que la imagen de esos operadores de onda es igual al espacio de estados absolutamente contínuos del Laplaciano compatible. Logramos esto último usando metodos dependientes del tiempo que provienen del estudio de operadores de Schrödinger de varios cuerpos.

AbstractIn this study, middle school students’ motivated strategies for learning were compared based on their learning styles. Four hundred fifty-one senior middle school students participated in this study. The sample comprised 52.3% female students and 47.7% male students. According to the results of the present study, the Concrete Experience and Reflective Observation learning preferences generally exhibit a negative correlation with the motivated strategies for learning whereas the Abstract Conceptualization and Active Experimentation learning styles mostly display a positive correlation with the motivated strategies for learning. Moreover, the students who have the Accommodating and Converging learning styles use motivated strategies for learning more frequently than the students who have the Diverging and Assimilating learning styles.Key words: learning style; learning strategy; middle school student; MSLQ. --- SažetakU ovome su istraživanju uspoređene voljne strategije učenja kojima se na temelju svojih stilova učenja koriste učenici viših razreda osnovnih škola. U istraživanju je sudjelovao četiri stotine pedeset i jedan učenik, od kojih su 52,3% bile djevojčice, a 47,7% dječaci. Rezultati su pokazali da učenici koji pokazuju sklonosti prema načinima učenja utemeljenima na konkretnom iskustvu i refleksivnom promatranju postižu negativnu korelaciju s voljnim strategijama, a da učenici koji se koriste stilovima apstraktne konceptualizacije i aktivnoga eksperimentiranja pokazuju pozitivnu korelaciju s voljnim strategijama učenja. Uz to, učenici koji se koriste akomodirajućim i konvergentnim stilom učenja koriste se voljnim strategijama učenja češće od učenika koji primjenjuju divergentan i asimilirajući stil učenja.Ključne riječi: stil učenja; strategija učenja; učenik višega razreda osnovne škole; Upitnik o voljnim strategijama učenja.

AbstractContents of materials hold an important place in the realization of the goals and tasks of initial physics and chemistry education in primary school teaching. Fourth grade students (11 years old) adopt basic concepts of various physical and chemical properties of materials. The aim of this paper is to determine the efficiency of student experiments and demonstration experiments in teaching physics and chemistry, in relation to the quality of student knowledge about materials. The research sample consisted of 136 fourth grade students in primary schools in Serbia. Experimental, comparative and descriptive - analytical methods were carried out. The survey instrument was a test (initial, final test and retest were conducted), containing two tasks on each cognitive level (Bloom-Anderson-Kratwohl taxonomy). Students who had independently performed experiments acquired greater knowledge about materials in relation to students to whom experiments have been demonstrated by the teacher. They achieved better results at the level of analysis, evaluation and creation. Key words: demonstration experiments; initial physics and chemistry education; student experiments; student knowledge of material properties.---SažetakSadržaji o materijalima zauzimaju važno mjesto u realizaciji ciljeva i zadataka početnog fizičko-kemijskog obrazovanja u razrednoj nastavi. Učenici 4. razreda (11 godina) usvajaju osnovne pojmove o različitim fizičkim i kemijskim karakteristikama materijala. Cilj rada je utvrđivanje učinkovitosti primjene demonstracijskih i učeničkih pokusa prilikom predavanja sadržaja fizike i kemije, u odnosu na kvalitetu znanja učenika o materijalima. Istraživanje je provedeno na uzorku od 136 učenika 4. razreda osnovnih škola iz Srbije. Korištena je eksperimentalna, komparativna i deskriptivno-analitička metoda. Instrument istraživanja je test (inicijalni, finalni test i retest) koji je sadržavao po dva zadatka putem kojih su se provjeravale sve kognitivne razine (Bloom-Anderson-Kratwohl taksonomija). Učenici koji su samostalno izvodili pokuse ostvarili su veća znanja o materijalima u odnosu na učenike kojima su pokuse demonstrirali učitelji. Postigli su bolje rezultate na razini analize, evaluacije i kreacije. Ključne riječi: demonstracijski pokusi, početno fizičko-kemijsko obrazovanje, učenički pokusi, znanja učenika o osobinama materijala.
Los modelos mixtos de teoría de respuesta al ítem
Authors: Brizuela Armel
Published: November 2015

Se presentan los modelos mixtos de teoría de respuesta al ítem y cómo estos pueden ser utilizados para identificar subagrupaciones no observadas de examinados denominadas como clases latentes. Asimismo se ejemplifica la utilidad del modelo mixto de teoría de respuesta al ítem de dos parámetros, mediante el cual se logra detectar la presencia de ítems en una escala de depresión que miden de manera distinta a los examinados en comparación con el resto de ítems que componen dicho instrumento. Finalmente, se presentan algunas recomendaciones generales en cuanto a la complementariedad que debe existir entre la teoría sustantiva que subyace al desarrollo de una escala y la aplicación de los modelos mixtos de teoría de respuesta al ítem.
No le tema a los datos perdidos: enfoques modernos para el manejo de datos perdidos
Authors: Montenegro-Montenegro Esteban , Oh Youngha , Chesnut Steven
Published: November 2015

La mayoría de los datos en ciencias sociales y educación presentan valores perdidos debido al abandono del estudio o la ausencia de respuesta. Los métodos para el manejo de datos perdidos han mejorado gramáticamente en los últimos años, y los programas computacionales ofrecen en la actualidad una variedad de opciones sofisticadas. A pesar de la amplia disponibilidad de métodos considerablemente justificados, muchos investigadores e investigadoras siguen confiando en técnicas viejas de imputación que pueden crear análisis sesgados. Este artículo presenta una introducción conceptual a los patrones de datos perdidos. Seguidamente, se introduce el manejo de datos perdidos y el análisis de los mismos con base en los mecanismos modernos del método de máxima verosimilitud con información completa (FIML, siglas en inglés) y la imputación múltiple (IM). Asimismo, se incluye una introducción a los diseños de datos perdidos así como nuevas herramientas computacionales tales como la función Quark y el paquete semTools. Se espera que este artículo incentive el uso de métodos modernos para el análisis de los datos perdido

Published: November 2015

Se usó un diseño cuasi-experimental con pre y post-test para estimar el efecto de una capacitación para la prueba de admisión de la Universidad Costa Rica, un test estandarizado que mide habilidades de razonamiento en contextos verbales y matemáticos. Cuatro colegios públicos del área metropolitana central del país participaron en el estudio, asignándose dos de ellos aleatoriamente al grupo de intervención y los otros dos al grupo de control, con 61 estudiantes en el primer grupo y 80 en el segundo. La intervención consistió de 5 sesiones de capacitación de 3 horas, utilizando como guía un manual desarrollado por una experta pedagoga, con enfoque constructivista. Las medidas antes y después fueron formas reducidas de la prueba de admisión 2014. La variable dependiente fue la diferencia entre ambas mediciones. El efecto de la capacitación fue de 3.5 puntos porcentuales y significativo, y se estimó utilizando un modelo bayesiano de regresión multinivel.
Los Plinios, la Campania romana y las erupciones plinianas
Authors: Soto Bonilla Gerardo J.
Published: November 2015

Este trabajo aporta nuevas líneas de discusión sobre cuatro aspectos relacionados con los Plinios, el Viejo y el Joven. Primero, el pobre conocimiento que se tenía en el siglo I, del Vesubio como un volcán, incluso por naturalistas como Plinio el Viejo, y entonces, la sorpresiva erupción del año 79. Segundo, el aporte de Plinio el Viejo a la defensa civil de la Roma antigua, pues asistió a los afectados durante la erupción, en donde encontró la muerte. El tercero es sobre las causas reales de la muerte de Plinio el Viejo, por asfixia relacionada con corrientes piroclásticas diluidas. El último punto se relaciona con el aporte de ambos Plinios a la Vulcanología y la justicia de que el nombre “erupciones plinianas” debería ser en honor a ambos y no solo al sobrino.
