Estimating the state of a geophysical system with sparse observations: time delay methods to achieve accurate initial states for prediction
Authors: An Zhe , Rey Daniel , Ye Jingxin , Abarbanel Henry D. I. 
Published: January 2017

Abstract. The problem of forecasting the behavior of a complex dynamical system through analysis of observational time-series data becomes difficult when the system expresses chaotic behavior and the measurements are sparse, in both space and/or time. Despite the fact that this situation is quite typical across many fields, including numerical weather prediction, the issue of whether the available observations are "sufficient" for generating successful forecasts is still not well understood. An analysis by Whartenby et al. (2013) found that in the context of the nonlinear shallow water equations on a β plane, standard nudging techniques require observing approximately 70 % of the full set of state variables. Here we examine the same system using a method introduced by Rey et al. (2014a), which generalizes standard nudging methods to utilize time delayed measurements. We show that in certain circumstances, it provides a sizable reduction in the number of observations required to construct accurate estimates and high-quality predictions. In particular, we find that this estimate of 70 % can be reduced to about 33 % using time delays, and even further if Lagrangian drifter locations are also used as measurements.
Africa as Tradition in U.S. African American Muslim Identity
Authors: Khabeer Su’ad Abdul 
Published: January 2017

Abstract
In this article I take up David Scott's “heuristic of tradition” to examine Africa as tradition in African American Muslim identity. First, I explore the structure and narrative of claims made for and to Africa by U.S. African American Muslims. Second, I ask: When U.S. African American Muslims claim an Islamic African past, to whom are they speaking and to what ends? I contend that U.S. African American Muslims find themselves neither Muslim enough to be authoritative to non-Black Muslims nor Muslim enough to be representative of U.S. American Muslims in the U.S. American popular imagination. In this context, I also trace the genealogical claims to an Africa made through hip-hop to demonstrate how a sonic religious lineage recenters U.S. African American Muslims within the broader U.S. Muslim community. Thus, I argue that as tradition, Africa labors against the erasure of the U.S. African American Muslim as legitimately Muslim.
Fuel Prices and Station Heterogeneity on Retail Gasoline Markets
Authors: Haucap Justus , Heimeshoff Ulrich , Siekmann Manuel 
Published: January 2017

ABSTRACT We empirically investigate how and why price levels differ across gasoline stations, using the first full year from a novel panel data set including price quotes from virtually all gas stations in Germany. Our analysis specifically explores the role of station heterogeneity in explaining price differences across gasoline stations. Key determinants of price levels are found to be ex-refinery prices as key input costs, a station’s location on roads or highway service areas, and brand recognition. A lower number of station-specific services implies lower fuel price levels, as does a more heterogeneous local competitive environment.
The Effect of Information on TOU Electricity Use: An Irish Residential Study
Authors: Pon Shirley 
Published: January 2017

ABSTRACT The disconnect between the time of use and the time of payment is sometimes blamed for the little awareness that many consumers appear to have about their usage of electricity. Real time information feedback combined with various pricing schemes has been found to reduce residential energy consumption more than information and pricing policies alone. I examine the effect of information provision with bi-monthly billing, monthly billing, and in-home displays in addition to a time-of-use pricing scheme on consumption over each month of the Irish Consumer Behavior Trial. I find that time-of-use pricing with real time usage information reduces electricity usage up to 8.7 percent during peak times at the start of the trial but the effect becomes indistinguishable from other treatment groups after the first three months. Increasing billing reports to the monthly level or a web application providing real time information may be more cost effective than in-home displays.
Mortality-risk valuation, age and cause of death: out-of-hospital cardiac arrest
Authors: Sund Björn 
Published: January 2017

Economic evaluation of policies regarding out-of-hospital cardiac arrest (OHCA) is important. The value of a statistical life (VSL) for OHCA victims is the most important component in a cost-benefit analysis of interventions that have the possibility to reduce mortality from this cause. This value is not known. We use responses to a national Swedish mail survey, based on the stated-preference technique to directly elicit individuals’ hypothetical willingness to pay for a reduced risk of dying from OHCA. A lower-bound estimate of VSL for OHCA would be in range of SEK 30 to 50 million. The value is found to be higher than for comparable VSL estimates from the transport sector, even though individuals who suffer OHCAs are generally older and less healthy than people who die in road traffic accidents. The results indicate that it is not an overestimation to use the ‘baseline’ VSL value from the transport sector (SEK 24 million) in cost-benefit analysis of OHCA policy decisions and that the cause of death is important when examining willingness to pay for death risk reductions. We do not support a general declining VSL due to the age of the victims, i.e. a ‘senior death discount’, for this cause of death.Published: Online January 2017. In print December 2017.
Competencias socioemocionales y percepción de la comunidad ante la conducta agresiva en adolescentes que viven en entornos de riesgo

Published: January 2017

ResumenSegún las encuestas internacionales, los jóvenes de América latina se muestran preocupados por el clima de violencia en sus comunidades. Este trabajo busca identificar el rol de las competencias socioemocionales como factor de protección ante las conductas agresivas en los jóvenes. Se encuestaron a 970 estudiantes de secundaria que residen en contextos considerados como de riesgo psicosocial. Los resultados apuntan a que la percepción del riesgo parece tener un mayor impacto en los varones, manteniendo su nivel predictivo incluso al controlar las competencias socioemocionales, no así con las mujeres. Estos hallazgos se discuten a la luz de otros estudios en los que se señala la vulnerabilidad del sector masculino ante la violencia comunitaria. Así mismo se destaca el rol del manejo del enojo, las competencias interpersonales y la generación de un estado de ánimo positivo con la finalidad de sugerir acciones sociales destinadas a la reducción de la violencia. AbstractAccording to international statistics, Latin America young people are shown concerned by the violence climate in their communities. This paper seeks to identify the role of socioemotional competences as a protection factor against aggressive behaviors in young people. 970 middle school students which inhabit in a context of psychosocial risk were inquired. The results showed that risk perception seems to have bigger impact in men, keeping its predictive level, even when it controls socioemotional capabilities, unlike women. These findings are discussed at the light of other studies in which vulnerability of male sector against communitarian violence is highlighted. Likewise, anger management’s role, interpersonal capabilities and the formation of a positive mood with the aim of suggesting social actions targeted towards violence reduction are pointed out.
Ciencias no divinas: ciencia y cultura en el helenismo
Authors: Rada García Eloy 
Published: January 2017

La evolución de la cultura humana es un largo proceso cuya explicación han intentado los historiadores desde los más diversos puntos de vista. La complejidad del desarrollo y sucesión de las culturas exige comprender por igual lo que surge como novedad y lo que permanece, explícito o implícito, en las sucesivas formas culturales. La Historia heroica (de los hechos gloriosos o catastróficos) no basta para ello. Otra forma de ver el continuo socio-cultural (darwiniano o cuasi-darwiniano, en clara analogía con el biológico) permite comprender el proceso en términos de “descendencia con variación” de “supervivencia del mejor adaptado”, etc., siempre que estas categorías explicativas se entiendan también analógicamente en su contexto cultural-antropológico. Se ha repetido innumerables veces que nuestra cultura es de origen griego y se habla de la “herencia clásica”, como si de una dote conocida y compartida se tratase. Aquí pretendo mostrar, primero y esquemáticamente, la complejidad cultural acumulada en la cultura historiográfica helenística y, después, señalar algunos factores, tanto griegos como exógenos, incorporados a ese legado y trasmitidos en él hasta nuestros días. La consideración memética, aquí implícita, de todos estos factores permite una interpretación naturalista de la evolución cultural que ha llegado hasta el presente. Puede ser relevante que, además de los entramados sociales, entre esos factores se hallen principalmente la ciencia, las técnicas o los cultos sociales junto con las concepciones filosóficas o religiosas. Sin embargo, la mayor relevancia reside, tal vez, en la posibilidad metodológica de comprender más radicalmente los procesos culturales en términos naturalizados. Tomamos al Helenismo como ensayo.
Historia de la Polémica sobre la introducción de la Lógica Difusa
Authors: Garrido Bullón Ángel 
Published: January 2017

Los problemas de incertidumbre, imprecisión y vaguedad se han debatido durante muchos años. Estos problemas han sido temas importantes en los círculos filosóficos, con muchos debates, en particular, acerca de la naturaleza de la vaguedad y la capacidad de la lógica booleana tradicionales para hacer frente a los conceptos y percepciones que son imprecisas o vagas. La lógica difusa (que se suele traducir al castellano por "Lógica Borrosa", o "Lógica Difusa", pero también por "Lógica Heurística") puede ser considerada una lógica divergente o una “deviant logic” (lógica multivaluada, MVL, en su acrónimo). Se basa en, y está estrechamente relacionada con, la teoría de los conjuntos fuzzy –borrosos o difusos-, y está aplicándose con creciente éxito en el tratamiento de información y el control de distintos sistemas difusos. Se podría pensar que la lógica difusa es muy reciente y que ha funcionado sólo desde hace poco tiempo, pero sus orígenes se remontan al menos a los filósofos griegos. Incluso parece posible rastrear sus orígenes en la China y la India antiguas. Porque parece que fueron ellos los primeros en tener en cuenta que todas las cosas no tienen por qué ser de un determinado tipo o dejar de serlo, sino que puede haber – y de hecho los hay- una amplia gama de estados intermedios. Es decir, que habrían de ser los pioneros en considerar que no deben ser sólo considerados un par de grados absolutos y totalmente contrapuestos, sino que puede haber –y de hecho la hay- toda una escala que abarca desde el mayor al menor grado tanto de verdad como de falsedad. En el caso de los colores, por ejemplo, entre el blanco y el negro hay toda una escala infinita: la de los tonos de grises. Algunos teoremas recientes muestran que en principio, la lógica difusa se puede utilizar para modelar cualquier sistema continuo que se base en la inteligencia artificial, o la física o la biología, o la economía, …, por tanto, en muchos campos se puede encontrar que los modelos difusos y la lógica de sentido común son los más útiles, y mucho más convenientes o adecuados que aquellos que son estándar, entre los que podríamos considerar la matemática clásica. Analizaremos aquí la historia y el desarrollo de este problema: el de la Vagueness, o de la Fuzziness, "Borrosidad" en castellano, que resulta esencial para trabajar con la incertidumbre.
Visionary Leadership, Team Building Competence, and Conflict Resolution Skills of School Administrators: Structural Model on Organizational Efficiency
Authors: ANDACAO ARVIN A. 
Published: January 2017

Several indicators of organizational efficiency that beset the Philippine System of Higher Education have been identified. In pursuit of total quality management in Philippine Higher Education Institutions (HEIs), the study determined the best fit model of organizational efficiency of State Universities and Colleges (SUCs) in Region XI, Philippines. The study employed descriptive correlational design and structural equation model with 369 faculty members who participated as respondents. Sets of survey questionnaires were also used as instruments in obtaining information from the respondents. The findings revealed that the overall level of visionary leadership of school administrators was high; team building competence was high; conflict resolution skills was barely high; and organizational efficiency of SUCs was high. Meanwhile, the visionary leadership, team building competence, and conflict resolution skills of school administrators were significantly correlated (p<0.01) with organizational efficiency. The commitment, accountability, shared goals, valuing, and mapping were found out to be the best predictors to achieve organizational efficiency. Finally, the most model parsimony for organizational efficiency of SUCs in Region XI, Philippines was the level of team building competence of school administrators, which passed all the conventions of a good model fit.

Writing Proficiency Program of Freshmen Students in Bohol Island State University Clarin, Bohol
Authors: BULILAN RAMIL S. 
Published: January 2017

Learning to write well is keeping a balanced diet. Toward this end, we sampled 250 freshmen students in Bohol Island State University, Clarin, Bohol, to determine their writing proficiency in identifying and revising sentences with structural slips, basis for a proposed Writing Proficiency Program. Descriptive correlational survey method, with interview and observation techniques, was used. As instrument, questionnaire with 1-hour item test revealed their profile and writing drawbacks. Manifested much difficulty was in identifying wordy sentences (91.52%) and stringy (97.40%) in transformation. Although they were proficient (2.68) in identification, but poor (3.28) in transformation. Chi-square contingency test showed significant result where the computed t-value (2.892) was greater than the tabular value (1.98). This implies that the hardest the sentence errors to identify, the hardest for them also to transform. Consequently, a designed 11-session Writing Proficiency Program is in order. This will address not only to this institution but throughout the other 5 campuses of BISU System. When approved by the Board of Regents, this becomes a graduation requirement for all students. Passers will receive Certificate of Merits. For its sustainability, such program shall be managed by competent language professorsand competent heads of offices who would be de-loaded and afforded honoraria.

A Comparison of the Effectiveness of the Lecture-Demo and Self-Instructional Module Methods in Teaching Basic LAPUNTI Arnis Strikes
Authors: EMPLEO-PACRES JOAN GRACE V. 
Published: January 2017

Like many other martial arts, arnis, the Philippines’s national martial art and sport characterized by stick-assisted or bare-handed fighting, is usually taught using methods often regarded as teacher-centered. Recently, however, physical education instructors have shown deepening interest in learning-oriented and student-centered approaches, which often fall under the umbrella concept of constructivism. This four-week experimental study using the post-test-only control group design compared two methods for teaching the 12 basic LAPUNTI (Labangon, Punta Princesa, Tisa)-style arnis strikes: the lecture-demo, generally held to be a teacher-centered method, and the printed self-instructional module, generally regarded as learner-centered and believed to foster active learning. The comparison was based primarily on post-test scores from the 47 students of the University of the Philippines Cebu who participated in the study. The rubrics-scored post-test was designed to determine the masterful and accurate execution of the basic LAPUNTI arnis strikes. Both experimental and control groups earned “Very High” mean scores, indicating comparable levels of post-instruction student performance. No significant difference was found between the lecture-method and self-instructional module method. The study found that the self-instructional module method was just as effectiveas the lecture-demo method in the teaching of LAPUNTI-style arnis strikes.

Critical Linguistic Analysis of Print Communications Used in Higher Education Institutions
Authors: Adriano Teresita Q. 
Published: January 2017

Explicit communication is imperative in building up relationships among members of organizations and institutions. This study described, critically analyzed and interpreted the linguistic features of the accessible print communications, which in effect brought out the communication culture, social and power relations of the members of the three tertiary institutions in Davao City. Results revealed a mixed sentence construction of declaratives and imperatives, actives and passives. Gratulatory and courteous expressions like More Power, God Bless, Please, Kindly, May I, marked significant presence in the prototype opening and closing fragments which these expressions have become standard parts of these memorandums. Variation among the structures was the divine exaltation (predictive of the culture of the university) found in the initial portion of the memorandums. Also noted was the legalese, archaic and formal tone, hereby and of the memorandum of the university president that was echoed in the memorandums of the student organization officers. An intensified writing training program in two categories: for new administrators and student officers have to be effected.
