Published: April 2017

We combined feld observations with isoenzyme analysis to compare population demographic and its effects on genetic diversity and mating systems, among six populations of sandalwood in Gunung Sewu, Indonesia, during March to August 2015. This endangered economic-important species was originated from the southeastern parts of Indonesia, but is recently occured as new landraces in Gunung Sewu, Java island. The observed heterozygosity varied from Ho 0.184 to 0.385 in parents, and from Ho 0.083 to 0.348 in offspring levels, based on the degree of clonality and genetic base. Most of genetic variation is distributed within populations, and only 2.7% were presented among populations, that was indicated by the low DST and FST value (HT 0.30; HS 0.276; DST 2.4%; FST 7.98%). A dendrogram indicated a grouping of populations into three clusters. However, there were seemed to be no association between geographical and genetic distance. Genetic depletion occured due to (i) clonality events as result of heavy-exploitation and/or natural disturbance which induced root suckering, (ii) genetic drifts and bottleneck effects, (iii) the founder effects due to parental low diversity, and (iv) the alteration on mating systems to be more inbreeders. Some of the results confrmed a “reproductive assurance prediction” while some others were contradicting this. It seemed that genetic diversity and mating systems are not much affected by population size, but more by the parental heterozygosity and the degree of clonality. Our results emphasized the importance of populations’ genetic base or parental genetic diversity to naturally maintain the genetic and evolutionary processes under equilibrium conditions.
¿Ideal democrático? Del activismo judicial a la constitucionalización del derecho
Authors: García López Luisa Fernanda 
Published: April 2017

La constitucionalización del derecho en Colombia obedece a una participación activa del juez, en particular del juez constitucional. El precedente judicial fuente del derecho es una muestra de la inclusión del juez en el escenario constitucional como garante de la democracia y del derecho. El ideal democrático incluye irreversiblemente al juez constitucional y sus interpretaciones. La sobreinterpretación del derecho responde a una interpretación amplia de la Constitución y a la construcción de normas que en algo contribuyen a llenar las lagunas del derecho. Con ello, el neoconstitucionalismo, es constitucionalizar el ordenamiento jurídico.

Value is in the Eye of the Beholder: The Relative Valuation Roles of Earnings and Book Value in Merger Pricing
Authors: Rabier MaryJane R. 
Published: April 2017

ABSTRACT
Gupta and Gerchak (2002) argue that different acquirers can arrive at different equity valuations for the same target depending on their strategic intent. A reason for acquirers' equity valuations to vary, holding target fundamentals constant, may be that individual acquirers place different weights on underlying fundamentals. I examine this possibility using Burgstahler and Dichev's (1997) theoretical framework. They argue that the relative importance of earnings and book value depends on expected adaptation, which is the likelihood that the existing earnings generating process will be altered. Using restructuring costs to proxy for expected adaptation at the individual acquirer level, I find that the association between the target's earnings (book value) and acquirers' bid prices is decreasing (increasing) in expected adaptation, consistent with theoretical predictions. These findings are less pronounced during merger waves and intense bid competition for the target.
The Effect of Industry-Specialist Auditors on SEO Underpricing Before and After the Global Financial Crisis
Authors: Kwon Soo Young , Park Jongwon , Yu Jaeyoon 
Published: April 2017

SUMMARY
This study examines whether auditors' industry expertise is negatively associated with underpricing of seasoned equity offerings (SEO) and whether the association between auditors' industry expertise and SEO underpricing changes around the global financial crisis (GFC). Using a sample of 2,028 SEO observations from 2001 to 2013, we document that in the pre-GFC period, auditors' industry expertise is negatively associated with SEO underpricing, but not during the post-GFC period. Industry-specialist auditors are also associated with higher earnings response coefficients in the pre-GFC period, but not in the post-GFC period. These results suggest that the GFC affected investor confidence in industry-specialist auditors in the capital markets.

Do Managers Make Voluntary Accounting Changes in Response to a Material Weakness in Internal Control?
Authors: Keune Marsha B. , Keune Timothy M. 
Published: April 2017

SUMMARY
This study examines whether managers make voluntary changes in accounting principle in response to a material weakness (MW). We find that managers are more likely to report voluntary changes in the same year as and year following a MW disclosure, a result largely driven by companies with a greater number of MWs. Although MW companies with new CFOs are more likely to make voluntary changes in the same year, restatements and new auditors, CFOs, CEOs, and directors are not the primary drivers of these results. Managers of MW companies justify voluntary changes as improving accounting information, conforming internal policies, and providing administrative benefits. MW companies that report voluntary changes in the same year and justify the changes as improving accounting are more likely to remediate at least one MW in the following year. Further, entity-level MW companies with voluntary changes in the same year are associated with higher accruals quality than other entity-level MW companies, and a similar result holds for companies with more MWs. These results suggest that MW companies likely report voluntary changes as part of a strategy to improve financial reporting processes and policies. Our study informs both internal control policymakers and accounting standards setters.

Published: April 2017

No campo de pesquisa da formação de professores que ensinam Matemática, sobretudo na literatura internacional, há um debate crescente e emergente acerca de materiais curriculares que possam atingir professores em larga escala e, ao mesmo tempo, potencializar sua aprendizagem. Nesse sentido, o presente artigo tem como objetivo apresentar concepções pelas quais pesquisadores conceituam materiais curriculares (educativos). Além disso, pretendemos discutir quatro concepções sobre usos de materiais curriculares educativos sistematizadas por Remillard (2005), bem como indicar limites e expandir esse estudo, apontando uma quinta concepção, a qual denominamos de recontextualizando o texto. Esta concepção baseia-se teoricamente no modelo do discurso pedagógico de Basil Bernstein (1990, 2000), explorado no corpo deste artigo. In the research field of teacher education that teaches Mathematics, especially in the international literature, there is a growing and emerging debate about (educational) curriculum materials that can reach teachers on a large scale and at the same time enhance their learning. This theoretical paper aims to present conceptions by which researchers conceptualize (educational) curriculum materials. In addition, we intend to discuss four conceptions on the uses of systematic educational curriculum materials in a study by Janine Remillard, as well as to indicate limits and expand this study, pointing out a fifth conception, which we call recontextualising the text. This conception is theoretically based on Basil Bernstein's model of pedagogic discourse.

Objetiva analisar as organizações praxeológicas matemática e didática referente ao estudo de números binários em uma coleção de livros didáticos de matemática do Ensino Fundamental. Primeiro se faz uma análise praxeológica matemática. Em seguida se analisa as organizações praxeológicas didáticas recorrendo aos critérios de avaliação praxeológica de Yves Chevallard. Não identifica estudo de sistema de numeração binário, mas sim o emprego do sistema numérico decimal nas unidades de medida da informática. Conclui que a coleção analisada caracteriza-se como uma praxeologia local. Identifica 6 tipos de tarefas, uma técnica implícita, uma única tecnologia e nenhuma teoria no volume 7 e 3 tipos de tarefas, uma técnica implícita, nenhuma tecnologia e nenhuma teoria no volume 8. This research aims to analyze the mathematical praxeological and didactic praxeological organizations referring to the study of binary numbers in a collection of mathematics textbook suited for the final years of elementary school. First it makes a praxeological mathematical analysis. Then it analyzes the didactic praxeological organizations and finally, it defines evaluation criteria and praxeological mathematics teaching. It does not identify binary numbering system of study, but the use of the decimal number system in computer measurement units. It concludes that the analyzed collection is characterized as a local praxeology. It identifies 6 types of tasks, an implicit technique, a unique technology and any theory in Volume 7 and 3 types of tasks, an implicit technique, no technology and any theory in volume 8.

Africanismos en el español de México
Authors: Lara Luis Fernando 
Published: April 2017

Fecha de recepción: 7 de octubre de 2014.Fecha de aceptación: 28 de mayo de 2015. Después de una revisión de lo que se conoce acerca de los esclavos africanos en Hispanoamérica desde el siglo xvi y las diferentes hipótesis que se han ofrecido acerca de la formación de un pidgin o incluso un protocriollo portugués-lenguas africanas, se explora el modo en que los africanos se asimilaron en la Nueva España, para resaltar la diferencia entre esta región y las demás de Hispanoamérica. Se muestra que la influencia de las lenguas africanas en el español mexicano se reduce al léxico, tanto en topónimos como en vocablos propios de la vida diaria. Se ofrecen sendas listas de africanismos con su discusión etimológica.
Lexicografía académica y lexicografía didáctica: ¿relaciones excluyentes o conceptos complementarios?
Authors: Hernández Humberto 
Published: April 2017

Fecha de recepción: 21 de julio de 2014.Fecha de aceptación: 29 de mayo de 2015. A pesar de que el reconocimiento e influencia de la Real Academia Española en la lexicografía hispánica ha sido enorme, nunca se planteó la Institución un cambio de orientación en sus planteamientos generales ni, desde una perspectiva más particular, una adecuación de los diccionarios a las exigencias de ciertos grupos de usuarios. Sin duda, una actitud excluyente entre “lo académico” y “lo didáctico”, la ausencia de unos objetivos claros en su política lexicográfica y no haber aprovechado suficientemente las posibilidades de sus propios recursos es lo que ha dado lugar, como se demuestra en este trabajo, a que el panorama lexicográfico académico se presente tan heterogéneo e inconexo.

The objective of this study was to investigate the occurrence of musculoskeletal symptoms in teachers of a Higher Education Institution (HEI) located in João Pessoa – PB. This is a descriptive research with a quantitative approach, held at the Faculties of Nursing and Medicine (FACENE/FAMENE), in the city of João Pessoa-PB. The instrument for data collection consisted of a form with objective questions and divided into two parts, the first with data characterizing the sample and the second with the Nordic Musculoskeletal Symptoms Questionnaire. The data were analyzed quantitatively in percentage numbers and distributed in graphs. The results indicated that 30 teachers accepted to participate in the study with female predominance (67%). The regions most affected in the last 12 months were: dorsal (60%), lumbar (53%), neck, shoulders, wrists and hands (47%). Of the teachers interviewed, 20% reported having had difficulties in routine activities due to discomfort in the cervical region and 27% reported having sought medical or physiotherapeutic care due to neck pain, while 20% due to pain in the shoulders, dorsal, wrist/hands and hip/thighs. As for the occurrence of symptoms in the last week, the regions with the highest frequency of pain were shoulders (40%), neck and dorsal (27%). The significant percentage in the regions cited certifies that they are the regions most burdened in the professors and, therefore, deserve special attention in possible projects of occupational preventive action. This research evidences the necessity of new approaches and deepening on the subject, including the formulation of intervention strategies in the process of sickness of teachers.

Introduction:
The Ministry of Health has provided for the girls population aged nine to 13 years, the quadrivalent vaccine against Human Papillomavirus as a preventive measure for cancer of the cervix, with the initial proposal to achieve 80% of this population.
Objective:
To analyze the vaccine coverage and the perspective of the target population about the vaccine against the Human Papillomavirus.
Methods:
This was a quantitative and qualitative field research in descriptive character, conducted through the Information System of the National Program for Immunization and with a sample of 86 adolescents in the city of São José do Egito/PE/BR.
Results:
The vaccination coverage showed a reduction in sequence of the vaccination schedules of 19,53% in the first phase of the campaign and of 24.07% in the second phase. It was also noted that lack accurate information for more than 50% of respondents, 15.11% had local and / or systemic reactions and 89,53% of them expect positive results with the vaccine against the Human Papillomavirus.
Conclusion:
The results showed a discontinuity in the prophylaxis scheme, but for the teenagers who took the vaccine there is confidence that the immunobiological has the desired effect, protecting them against viruses and future cancer of the cervix.

How to face the association between tobacco and psychosis?
Authors: Dantas Raphael Tavares , Júnior Wanderley Gonçalves Cordeiro , Moreira Marcial Moreno , Santos Lídia Coelho do Nascimento , De Oliveira Sidney Medeiros , Rolim Neto Modesto Leite 
Published: April 2017

Evidences suggest an association between tobacco and psychosis. However, the reasons why people with psychosis have a higher tendency to smoke than the general population are not yet clear. Recently, Gurillo et al. reported that daily use of tobacco is associated with an increased risk of psychotic disorder and an earlier age of onset of psychotic illness. His study also calculated a significant mean difference in age at onset, expressed in years, and estimated the prevalence of smoking in people with their first episode of psychosis. According to this and other findings, it could be said that the causes of the smoking-schizophrenia association are complex and cannot be explained solely as a result of some aspect of schizophrenia. Thus, new studies in this area are needed, as well as strategies that look for the monitoring of smoking effects in order to reduce it among individuals with schizophrenia.

Abstract
We present the first identification of a candidate precursor for an imminent red nova. Our prediction is based on the example of the precursor to the red nova V1309 Sco, which was retrospectively found to be a contact binary with an exponentially decreasing period. We explore the use of this distinctive timing signature to identify precursors, developing the observational and analysis steps needed. We estimate that our Galaxy has roughly 1–10 observable precursors. Specifically, we lay out the observational case for KIC 9832227, which we identified as a tentative candidate two years ago (Molnar et al. 2015, AAS Meeting #225 Abstracts 415.05). Orbital timing over the past two years has followed the tentative exponential fit. As of late 2015, the period time derivative went beyond the range found in other systems (

), a necessary criterion for a serious candidate. We estimate time of merger is the year 2022.2 ± 0.7. Double absorption line spectra confirm directly the 0.458-day light-curve is the orbital period of a contact binary system and yield a mass ratio

. Closer analysis of the Kepler timing data shows evidence of a component C with orbital period

days and

. An alternative interpretation of the long-term timing trend, that is, a light travel-time delay due to the orbit around a distant component D, is ruled out by the spectroscopic data for any nondegenerate star. Additional measurements are needed to test further the merging hypothesis and to use fully this fortuitous opportunity.
