Handgun Legislation and Changes in Statewide Overall Suicide Rates
Authors: Anestis Michael D. , Anestis Joye C. , Butterworth Sarah E. 
Published: February 2017

Objectives. To examine the extent to which 4 laws regulating handgun ownership were associated with statewide suicide rate changes. Methods. To test between-group differences in statewide suicide rate changes between 2013 and 2014 in all 50 states and the District of Columbia with and without specific laws, we ran analyses of covariance. Results. We found significant differences in suicide rate changes from 2013 to 2014 in states with mandatory waiting periods and universal background checks relative to states without such laws. States with both laws differed significantly from those with neither. No significant differences in rate changes were noted for open carry restrictions or gun lock requirements. Conclusions. Some state laws regulating aspects of handgun acquisition may be associated with lower statewide suicide rates. Laws regulating handgun storage and carrying practices may have a smaller effect, highlighting that legislation is likely most useful when its focus is on preventing gun ownership rather than regulating use and storage of guns already acquired. Public Health Implications. The findings add to the increasing evidence in support of a public health approach to the prevention of suicide via firearms, focusing on waiting periods and background checks.

Published: February 2017

Objectives. To compare the predictive power of synthetic absolute income measures with that of asset-based wealth quintiles in low- and middle-income countries (LMICs) using child stunting as an outcome. Methods. We pooled data from 239 nationally representative household surveys from LMICs and computed absolute incomes in US dollars based on households’ asset rank as well as data on national consumption and inequality levels. We used multivariable regression models to compare the predictive power of the created income measure with the predictive power of existing asset indicator measures. Results. In cross-country analysis, log absolute income predicted 54.5% of stunting variation observed, compared with 20% of variation explained by wealth quintiles. For within-survey analysis, we also found absolute income gaps to be predictive of the gaps between stunting in the wealthiest and poorest households (P < .001). Conclusions. Our results suggest that absolute income levels can greatly improve the prediction of stunting levels across and within countries over time, compared with models that rely solely on relative wealth quintiles.

<p class="p1">Agarwood (<em>Aquilaria malaccensis </em>Lank) is one of the forest wood that are continously exploited. Currently, the Indonesian export of agarwood is decreasing because its population is endangered by excessive logging. Agarwood propagations need technology for reproduction of agarwood seedlings and their fungal inoculum. <em>In vitro </em>technique for germination of recalsitrant seeds and micropropagation are technologies that can be used for propagation of agarwood seedlings. An experiment was done to develop techniques for <em>in vitro </em>germination and micropropagation of agarwood. The <em>in vitro </em>germination was done using two different techniques. Firstly, sterile seeds were germinated on an MS medium + 50 mg/l PVP, 50 mg/l GA, and 1 mg/l BA or kinetin. Secondly, sterile seeds were germinated on basal medium of MS, 1/2 MS medium, MS medium without vitamins, as well as on MS medium without pyridoxine, nicotinic acid and WPM. Shoot initiations and multiplications were done on MS and 1/2 MS media containing 1, 3, or 5 mg/l BA. The explants used were cotyledone nodes, terminal shoots, single node with leaf, and sinle node without leaf. The results showed that the seed germination rate on the different media ranged from 7,14 to 50%. The seed germination rate on the MS medium without vitamis was the highest. The best explants for shoot induction and multiplication was single node with leaf which was cultured on MS + 1 mg/l BA.</p>

<p class="p1">Aluminum toxicity is a major constraint to soybean production in acid soils. Since variabilities on Al tolerance in plants are very limited, mutation breeding, and <em>in vitro </em>selection were used to increase the variability. Three soyben genotypes were produced from cultivars Wilis and Sindoro that have been gamma irradiated and selected <em>in vitro </em>for their tolerance to Al on Al and low pH media. These genotypes and their original cultivars were then planted in a greenhouse in an acid soil on May 2001. The results showed that the plant performances were varied, some were shorter and more compact than the original. Based on the yield components, a number of plants from the genotypes showed higher than those of the control cultivars. These plants were considered more tolerant to Al than the original cultivars.</p>

KENYA PRIMARY SCHOOL TEACHERS’ PREPARATION IN ICT TEACHING: TEACHER BELIEFS, ATTITUDES, SELF-EFFICACY, COMPUTER COMPETENCE, AND AGE
Authors: Wambiri Gladwell Njeri , Ndani Mary Nyokabi 
Published: February 2017

Information and Communication Technologies (ICT) has become globally recognized as an effective medium for learning. The Kenyan government made a commitment to provide computers for use in teaching in primary schools. This is expected to enable teachers to integrate ICT in their teaching beginning in primary standard one. Teachers will directly implement the ICT project at the classroom level, so are very crucial players to its effectiveness. This article discusses the preparedness of lower primary school teachers for this implementation process regarding their beliefs and attitudes, computer competence, and computer self-efficacy. The authors argue that the provision of computers and other infrastructure in schools may not automatically lead to integration of ICT in schools unless the government addresses teachers’ beliefs and attitudes, computer competence and their self-efficacy. The authors recommend revision of the primary teacher education preparation syllabus and training practice for pre-service teachers in ICT pedagogy to enhance their preparation to integrate ICT in their teaching in primary school.

Mountain climbing path information has been widely available on the internet. However, to get information that suits the needs of climbers take time to browse and compare all the available information. The diversity of the search results content actually confuse the climbers. This research aims to provide a solution to the problems faced by climbers, by developing an information retrieval system for mountain climbing path using semantic technology (ontology) based approach . The system is developed by using two knowledge base (ontology), ontology Bahasa represents linguistic knowledge and ontology Mountaineering represents mountaineering knowledge. The system is designed to process and understand natural language input form. The process of understanding the natural language based on syntactic and semantic analysis using the rules of Indonesian grammar. The results of the research that has been conducted shows that the system is able to understand natural language input and is capable of detecting input that is not in accordance with the rules of Indonesian grammar both syntactically and semantically. The system is also able to use a thesaurus of words in the search process. Quantitative test results show that the system is able to understand 69% of inputs are taken at random from the respondents.

Authors: Winaya I Gede , Ashari Ahmad 
Published: February 2017

MongoDB is a database that uses document-oriented data storage models. In fact, to migrate from a relational database to NoSQL databases such as MongoDB is not an easy matter especially if the data are extremely complex. Based on the documentation that has been done by several global companies related to the use of MongoDB, it can be concluded that the process of migration from RDBMS to MongoDB require quite a long time. One process that takes quite a lot is transformation of relational database schema into a document-oriented data model on MongoDB. This research discusses the development transformation system of relational database schema to the document oriented data model in MongoDB. The process of transformation is done by utilizing the structure and relationships between tables in the scheme as the main parameters of the modeling algorithm. In the process of the modeling documents, it necessary to adjustments the specifications of MongoDB document that formed document model can be implemented in MongoDB. Document models are formed from transformation process can be a single document, embedded document, referenced document or combination of these. Document models are formed depending on the type, rules, and the value of the relationships cardinality between tables in the relational database schema.

It is different with the output throughput 85 Bit/Sekon - 550 Bit/Sekon that is too low and indicated that throughput is not sentitif against handover with the voice over internet protocol application.
La contribución de Ivone Gebara a la teología del siglo XXi en América Latina
Authors: Zamora González María Vanessa 
Published: February 2017

Históricamente, la mujer se ha visto al margen de la vida religiosa institucional, sumida en posiciones de menor jerarquía, en donde se ha visto disminuida su participación en la toma de decisiones y la incidencia teológica. Ante esta situación, la teología feminista ha surgido principalmente para rescatar y proteger el derecho y la dignidad de esta frente al imaginario religioso, fundamentalmente patriarcal y hegemónico. Dicho dogma, tiene una mirada crítica hacia la situación de la mujer dentro de las instituciones religiosas; también, posee y mantiene otra serie de objetivos que son mucho más amplios y que están relacionados con la búsqueda de un cambio en la lógica de poder que se encuentra presente, tanto en las culturas patriarcales como se ha vislumbrado en los espacios religiosos. En este contexto, Ivone Gebara se ha constituido en una de las téologas ecofeministas latinoamericanas más reconocidas que ha intentado reconstruir y restaurar la dignidad de hombres y mujeres a través de nuevas categorías de análisis y una nueva visión mucho más integradora del quehacer teológico actual. Este artículo busca presentar su contribución a la teología latinoamericana del siglo XXI.

La administración de la investigación en la Universidad Estatal a Distancia de Costa Rica: revisión histórica desde 1977 hasta 2006
Authors: Barrientos Amador Maynor 
Published: February 2017

Este artículo llena un vacío institucional al poner en perspectiva histórica la evolución de la administración de la investigación en la UNED. Por medio de una exhaustiva revisión documental y una comparación analítica, se establecen cinco etapas de evolución bien diferenciadas marcadas por el desarrollo de congresos universitarios, la promulgación de políticas y el desarrollo y colapso de diferentes unidades académicas y administrativas relacionadas con la investigación en la UNED. El estudio se realizó durante el 2006 y sirvió como antecedente a la propuesta de creación de la Vicerrectoría de Investigación de la UNED, que comenzó a funcionar en 2007. Se evidencia que la historia de la investigación en la UNED ha acompañado la historia misma de la Universidad y ha estado vinculada de forma directa o indirecta a hitos universitarios de trascendencia, a la generación de documentos y discursos diversos, y a la transformación de instancias relacionadas con la investigación en la UNED a través de los año . Se espera que este artículo sirva de referencia a futuros estudios relacionados con la temática de la administración de la investigación en la UNED.
Live Learning: Online Teaching, Digital Literacy and the Practice of Inquiry
Authors: Casey Leo , Hallissy Michael 
Published: February 2017

There has been significant discussion in recent times around improving the quality of teaching and learning in higher education (Laycock, 2009; Laurillard & Masterman, 2010; DES, 2010). The Lisbon Strategy (Commission to the Council and the European Parliament, 2006) has framed much of this discussion at a European level with individual countries, such as Ireland, developing their own-targeted strategies to expand and improve higher education (DES, 2010). In the case of Ireland, these strategies specifically mention the need for institutions to provide ‘excellent teaching’ whether in face-to-face or online settings. Whereas there is a significant body of on-going research conducted around effective teaching in traditional, face-to-face settings in higher education (for example, Bennett & Barp, 2008, Beetham & Sharpe, 2007) there is, in recent times, an emerging need for investigations that focus on new contexts for teaching particularly in online synchronous classrooms.Many institutions have invested substantial time and resources in procuring new technology systems to support on-line teaching and in training staff to operate the many varied functions within these technologies. However, there is also a need to go beyond mere functionality and to provide deeper pedagogical support to faculty so they can fully realise the instructional potential of these systems (Kim & Bonk, 2006; Lee & Hirumi, 2004). Technological innovations in the area of online teaching lead to new challenges for teachers and educators as new tools are developed and adopted by their institutions. A question for researchers is the extent to which these tools augment or inhibit existing roles and practices in the classroom and to ask how we can conceptualize learning and teaching in such contexts.The case for considering inquiry learning as the ‘telos’ or central purpose of classroom practice is presented here. In this way the live on-line classroom is conceived as a communal learning space where teacher and students participate in activities that are enabled, sustained and enriched by the functionality of the technology system.
Factors That Influence Accounting Faculty Career Satisfaction: Comparisons by Program Prestige and Tenure Status
Authors: Fleischman Gary M. , Stephenson Teresa , Walker Kenton B. , Cook Kirsten A. 
Published: February 2017

SYNOPSIS
We report results of 266 surveys from untenured and tenured accounting faculty employed by both elite and non-elite accounting programs concerning factors that influence career satisfaction. We find that accounting academics are somewhat satisfied with their jobs, although factors that enhance or impair career satisfaction differ for faculty at elite versus non-elite programs and for untenured versus tenured faculty. Our findings suggest noteworthy implications for the accounting academy and provide insights about cultural differences between elite versus non-elite accounting programs.

Did the 1999 NYSE and NASDAQ Listing Standard Changes on Audit Committee Composition Benefit Investors?
Authors: Kim Seil , Klein April 
Published: February 2017

ABSTRACT
In December 1999, the SEC instituted a new listing standard for NYSE and NASDAQ firms. Listed firms were now required to maintain fully independent audit committees with at least three members. In July 2002, the U.S. Congress legislated these standards through the Sarbanes-Oxley Act. Our research question is whether all investors benefited from the 1999 new rule. Using both an event study and a difference-in-differences methodology, we find no evidence of higher market value or better financial reporting quality resulting from this rule.

Published: February 2017

OBJECTIVE
We aimed to determine the effect of elevated BMI over time on the progression to type 1 diabetes in youth.

RESEARCH DESIGN AND METHODS
We studied 1,117 children in the TrialNet Pathway to Prevention cohort (autoantibody-positive relatives of patients with type 1 diabetes). Longitudinally accumulated BMI above the 85th age- and sex-adjusted percentile generated a cumulative excess BMI (ceBMI) index. Recursive partitioning and multivariate analyses yielded sex- and age-specific ceBMI thresholds for greatest type 1 diabetes risk.

RESULTS
Higher ceBMI conferred significantly greater risk of progressing to type 1 diabetes. The increased diabetes risk occurred at lower ceBMI values in children &lt;12 years of age compared with older subjects and in females versus males.

CONCLUSIONS
Elevated BMI is associated with increased risk of diabetes progression in pediatric autoantibody-positive relatives, but the effect varies by sex and age.
La educación a distancia como mecanismo de inclusión social en las Universidades del Ecuador
Authors: Rea Fajardo María Soledad , Medina Crespo José Alberto 
Published: February 2017

La inclusión social en la educación superior es un tema que se encuentra en las políticas educacionales de algunos países latinoamericanos, entre ellos Ecuador. Las Instituciones de Educación Superior juegan un rol protagónico para el fortalecimiento del talento humano profesional que se necesita para el desarrollo de un país. Con la llegada de las Tecnologías de la Información y la Comunicación, la educación a distancia tomó más auge. Desde el punto de vista social, esta modalidad tiene la finalidad de dar acceso a aquellas personas que por diferentes limitantes no podrían asistir físicamente al aula de clases. La tecnología permite complementar lo presencial por lo virtual, propiciando que el espacio y tiempo se adapten a las necesidades de docentes y estudiantes. Además, de permitir que el estudiante se vuelva el protagonista de su aprendizaje y constructor del conocimiento. Los entornos virtuales de enseñanza – aprendizaje remplazan a los edificios. En fin, aparecen escenarios y herramientas digitales que potencian el aprendizaje colaborativo y el conocimiento abierto, aunque también generan controversias. A pesar de que hay muchos factores tecnológicos que facilitan la educación a distancia, es importante que se determinen las razones por las que hay personas que aún se sienten excluidas de las instituciones de educación superior. Por otro lado, las universidades ecuatorianas tienen el reto de articular a su gestión las nuevas políticas educacionales y buscar mecanismos para retroalimentar su pertinencia social.
