Simulación de problemas probabilísticos
Authors: Ramírez Arce Greivin 
Published: December 2015

<p>La simulación computacional de problemas de probabilidad permite obtener sus soluciones a través de la frecuencia relativa del número de éxitos obtenidos en los n experimentos realizados. La ley de los grandes números respalda una buena aproximación de la probabilidad teórica de un evento a través de la repetición sucesiva de experimentos. A continuación se presentan una serie de problemas probabilísticos con una posible simulación realizada en los paquetes Fathom y Excel. La solución teórica de estos problemas requiere conocimientos básicos de probabilidad, por lo que las simulaciones realizadas buscan dar una propuesta de solución a estos problemas sin tener que acudir al formalismo matemático.</p>

Published: December 2015

<p>La investigación tuvo por objeto determinar el contenido de humedad-equilibrio (CHE) de la madera por año, época y estación en Puerto Maldonado y predicción anual para Huánuco y Lima. El método seguido fueron en base a los procedimientos de las normas ASTM, D – 2395 e INDECOPI-251 011, metodología que consistió en medir instantáneamente las probetas de madera y secar en estufa las mismas, que nos sirvió para determinar el CHE, peso actual (Pa) midiendo una vez por semana durante un año, calcular la densidad básica (DB) de la madera y estimar el peso específico de la pared celular (Gbpc). El CHE de la madera promedio al año fue 12,63 % variando de 9 a 16 % rango entre 0,92 a 0,27 g/cm3 de DB, con un coeficiente de variación del CHE mayor en maderas de menor DB. El CHE por estaciones en Puerto Maldonado fue en verano 13,48 %, otoño 12,85 %, invierno 12,12 % y primavera 12,03 %, y en la época seca 12,12 % y época lluviosa 13,13 %, donde existió diferencia estadística significativa para especies maderables, estaciones y épocas, excepto cuando se compara medias de estación de invierno con primavera. La Gbpc promedio fue 1,419 y varió de 1,578 a 1,339, que permitió con la ecuación de Pérez et al., estimar el CHE para Puerto Maldonado 13,19 %, Lima 15,17 % y Huánuco 12,77 %.</p>

Applying Variance Analysis to Understand California Hospitals' Expense Recovery Status by Patient Groups
Authors: Bai Ge 
Published: December 2015

SYNOPSIS
I apply variance analysis, a management accounting tool, to examine California hospitals' expense recovery status in 2012, as compared with 2004, for three mutually exclusive groups of patients. For every $100 total operating expense incurred in 2012, as compared with those incurred in 2004, California hospitals received $3.2 more from public programs (a $0.7 rate effect and a $2.6 proportion effect), $3.0 more from private programs (a $7.8 rate effect and a −$4.8 proportion effect), and $2.2 less from uninsured patients (a −$3.1 rate effect and a $1.0 proportion effect). These results imply that (1) hospitals were able to charge increasingly higher prices to private insurers, and (2) hospitals received less revenue from uninsured patients, a possible consequence of the passage of California's Hospital Fair Pricing Act in 2006. My study highlights the applicability of variance analysis in understanding the temporal change in financial status for patient groups in the hospital industry.
The Role of Account Subjectivity and Risk of Material Misstatement on Auditors' Internal Audit Reliance Judgments
Authors: Bhattacharjee Sudip , Maletta Mario J. , Moreno Kimberly K. 
Published: December 2015

SYNOPSIS
Using a field-based questionnaire, we examine how auditors simultaneously use client-level misstatement risk (inherent risk and control risk) with account subjectivity when utilizing internal audit. We contend that auditor use of internal audit will reflect a balance of the costs and benefits of using internal audit. Prior audit research has primarily focused on lower and higher risk conditions, with relatively few studies examining the implications of moderate risk on internal audit use. Data on actual audits from an instrument administered to external auditors reveal significant differences in reliance decisions across lower, moderate, and higher misstatement risk levels. Results reveal that increases in account subjectivity have no effect on auditors' internal audit reliance when risk of material misstatement is at lower levels. However, auditors increase their internal audit reliance when account subjectivity increases across moderate misstatement risk. Finally, our results suggest that auditors decrease their internal audit reliance when account subjectivity increases across higher misstatement risk. By examining these risk variables in combination, we provide insight into the complexities associated with external auditors' internal audit usage. This research could be of interest to practitioners and academics by providing insight into how multiple risk factors may be combined when utilizing internal audit.
A Robust Approach For Acoustic Noise Suppression In Speech Using ANFIS
Authors: Martinek Radek , Kelnar Michal , Vanus Jan , Bilik Petr , Zidek Jan 
Published: December 2015

Abstract
The authors of this article deals with the implementation of a combination of techniques of the fuzzy system and artificial intelligence in the application area of non-linear noise and interference suppression. This structure used is called an Adaptive Neuro Fuzzy Inference System (ANFIS). This system finds practical use mainly in audio telephone (mobile) communication in a noisy environment (transport, production halls, sports matches, etc). Experimental methods based on the two-input adaptive noise cancellation concept was clearly outlined. Within the experiments carried out, the authors created, based on the ANFIS structure, a comprehensive system for adaptive suppression of unwanted background interference that occurs in audio communication and degrades the audio signal. The system designed has been tested on real voice signals. This article presents the investigation and comparison amongst three distinct approaches to noise cancellation in speech; they are LMS (least mean squares) and RLS (recursive least squares) adaptive filtering and ANFIS. A careful review of literatures indicated the importance of non-linear adaptive algorithms over linear ones in noise cancellation. It was concluded that the ANFIS approach had the overall best performance as it efficiently cancelled noise even in highly noise-degraded speech. Results were drawn from the successful experimentation, subjective-based tests were used to analyse their comparative performance while objective tests were used to validate them. Implementation of algorithms was experimentally carried out in Matlab to justify the claims and determine their relative performances.
Les francs-maçons à l'Orient de Douai (1800-1851) : Description sociale d'un groupe en mouvement
Authors: Roland Ed. 
Published: December 2015

Le but de cette étude a été de recenser et de dénombrer les francs-maçons douaisiens durant la première moitié du 19e siècle puis de décrire cette population maçonnique sous ses différents angles et ceci en prenant en compte les évolutions survenues au cours de la période considérée.
L'histoire sociale de la Loge de Douai présente un mouvement progressif qui s'est opéré au fil des ans dans le recrutement : repli géographique sur l'environnement urbain immédiat, importance croissante des notables locaux, augmentation régulière de la moyenne d'âge, représentation toujours accrue des métiers du négoce et baisse régulière du nombre et de l'influence des «inactifs», rentiers et propriétaires au profit des catégories sociales les plus dynamiques, ce mouvement de longue durée étant marqué par une rupture brutale qui voit la Loge rajeunir considérablement ses effectifs et recruter dans des catégories sociales nettement plus modestes à partir de 1844.
Il reste maintenant à rechercher les conséquences éventuelles de cette rupture sur le fonctionnement de la Loge et à étudier l'action des francs-maçons dans la vie de leur cité.
La mobilité des mineurs du charbonnage du Bois-du-Cazier (1900-1945)
Authors: Chapelle-Dulière Jacqueline 
Published: December 2015

Deze studie toont aan hoe groot, in een eerste stadium, de mobiliteit van de mijnwerkers van Bois-du-Cazier wel was, hoe gemakkelijk zij hun verblijf aldaar korter maakten, voor een tijd weggingen, en verder hoe weinig jongeren nog mijnwerker wilden worden. In het begin van de eeuw wil de mijnwerker veel verdienen ; naar een andere mijn gaan om meer te verdienen is dan ook gewoon. Zo is de mijnwerker bijna een reiziger van beroep.
Na de crisis van 1929 en meer nog tijdens de oorlog verandert de mobiliteit naar de omgeving in labiliteit binnen de mijn : de mentaliteit is veranderd. Het gaat er nu om ontsnappen aan werk dat als niet valoriserend beschouwd wordt en dat men alleen nog uit strikte noodzaak aanvaardt. Men gaat naar de mijn werken in de hoop zo snel mogelijk ander werk te vinden. Het gaat in wezen om de ontmoediging van de mijnwerker die niet langer de achting van de bevolking geniet.
Application of a Regenstrief RELMA V.6.6 to Map Russian Laboratory Terms to LOINC
Authors: Kopanitsa G. 
Published: December 2015

SummaryBackground: Manual mapping of laboratory data to Logical Observation Identifiers Names and Codes (LOINC) requires a major effort. Application of the LOINC mapping assistant RELMA V.6.6 can reduce the effort required for mapping. The goal of the paper is to perform a semi-automated mapping of Russian laboratory terms to LOINC.Methods: A semi-automated mapping of the 2563 terms from two clinics in Russia was performed. The first step was automatic mapping using RELMA V.6.6 and LOINC V.2.48 Russian translation by Yaroslavl state medical academy. The second step was a manual expert mapping. To evaluate the correctness of mapping all the mapped terms were reviewed by two experts.Results: The paper presents the results of semi-automatic mapping of Russian laboratory terms to LOINC. Two clinics (A and B) and a laboratory service participated in the project. The following results were achieved: mapping of 86% terms from Clinic A and 87% from Clinic B. It has to be mentioned that 99% of terms used in 2014 were mapped. In total 2398 out of 2563 were mapped.Discussion: The required effort was reasonable and the price of mapping and maintenance was considered as relatively low in comparison to manual methods.Conclusion: RELMA V.6.6 and LOINC V.2.48 offer the opportunity of a low effort LOINC mapping even for non-English languages. The study proved that the mapping effort is acceptable and mapping results are on the same level as the manual mapping.

Published: December 2015

Objective.We investigated the effects of chronic rheumatic and musculoskeletal symptoms on the functional status of people affected by the chikungunya (CKG) epidemic in the Calicut District, Kerala, South India in 2009.Methods.A cross-sectional house-to-house survey was conducted 18 months after the CKG epidemic to assess functional status of individuals with post-epidemic persistent pain. All respondents over age 15 years with persistent pain fitting the epidemiological case definition were included. Participants’ functional status was assessed using the Health Assessment Questionnaire-Disability Index (HAQ-DI). Factors affecting severity of HAQ-DI were analyzed by ordinal regression.Results.Of 3869 subjects interviewed, 1195 (34.3%) had a positive history of CHIKV virus infection (epidemiological or confirmed); 36.28% (624/1720) of CKG-affected individuals had persistent pain 18 months post epidemic. Mean age of those affected was 48.22 ± 15.6 years; 23.2% had no disability, while 16.2% had moderate to severe disability on the HAQ-DI. Significant factors affecting severity of disability on HAQ-DI included previous rheumatic musculoskeletal disease (OR 2.27), joint and soft-tissue involvement (OR 3.74), only joint involvement (OR 2.14), female sex (OR 1.44), diet (OR 4.73), and history of joint swelling (OR 1.72).Conclusion.Persistence of pain noted in post-CKG disease resulted in significantly deteriorated functional status of those affected.

Published: December 2015

Objective.To compare the outcomes between vascular surgery and endovascular procedures in a cohort of patients with Takayasu arteritis (TA).Methods.A retrospective cohort study was conducted of patients with TA who underwent vascular interventions at a tertiary center between 1984 and 2009. The American College of Rheumatology criteria for TA were used to select patients. Disease activity was assessed according to the Kerr criteria. Data are reported using descriptive statistics and Kaplan-Meier methods for complication rates.Results.The cohort included 66 patients with TA who underwent 119 vascular procedures (surgery 93; endovascular repair 26). The most frequent indication for vascular surgery and endovascular procedure was arm claudication (surgical group 43%, endovascular repair group 31%). In 59% of the vascular surgical procedures and in 38% of endovascular procedures, the disease was active within 1 month of intervention. The most frequent arterial lesion requiring intervention was the aorta (28%) in the vascular surgery group and the subclavian (35%) in the endovascular repair group. Early complications occurred after 15 surgeries and 4 endovascular repair procedures (p = 0.93). Late complications occurred after 34 surgical procedures and 10 endovascular repair procedures (44% vs 66%, respectively; p = 0.33). The majority of complications in both groups were restenosis. Hypertension, dyslipidemia, and higher doses of corticosteroids were associated with an increased risk of postprocedural complications and restenosis.Conclusion.In patients with TA, both open surgical and endovascular revascularization procedures are associated with high failure rates and frequent operative complications. Traditional cardiovascular risk factors, corticosteroid dose, and active disease are risk factors for restenosis after revascularization procedures.
Le management par la performance dans le secteur public local français : Un modèle plus administratif que politique
Authors: Favoreu Christophe , Carassus David , Gardey Damien , Maurel Christophe 
Published: December 2015

L’objet de cette recherche est d’analyser et de caractériser les pratiques des collectivités locales françaises dans le domaine du management de la performance. Pour ce faire, et dans un premier temps, une grille d’analyse théorique des différents modèles de gestion par la performance locale est proposée. Dans un second temps, cette grille est mobilisée et testée empiriquement afin d’appréhender la nature du modèle français de gestion par la performance locale. Les résultats de notre recherche démontrent l’existence d’un modèle français de type « administration de la performance », se traduisant par des tendances communes aux collectivités locales françaises en ce qui concerne le contenu instrumental et méthodologique, ainsi que les modes de pilotage de la performance publique. Remarques à l’intention des praticiens Les apports managériaux et pratiques de cette recherche portant sur les démarches locales de performance sont deux ordres. Premièrement, elle permet de disposer d’un cadre analytique et évaluatif de ce type de démarche, structuré non seulement autour d’outils de planification, de responsabilisation et d’évaluation, mais aussi de modalités de pilotage. Cette étude permet, deuxièmement, de connaître et de caractériser l’état des pratiques françaises en la matière, ainsi que leurs limites par rapport à des pratiques internationales plus matures. Ainsi, une collectivité locale s’engageant dans cette voie peut dès lors s’appuyer sur cette étude pour déterminer le périmètre et la structure des outils à mobiliser en fonction de la finalité suivie, qu’elle soit de de nature administrative et/ou politique.
Les motifs du partage des connaissances dans le secteur public : Le rôle de la motivation de service public
Authors: Chen Chung An , Hsieh Chih-Wei 
Published: December 2015

La littérature sur les motifs de partage des connaissances s’intéresse à l’importance des motivations à la fois extrinsèques et intrinsèques en matière de partage des connaissances. Cependant, pour élaborer une théorie en matière de motifs de partage des connaissances dans le secteur public, il convient de prendre en considération son contexte particulier, la principale préoccupation de l’État étant liée au service public, et non aux bénéfices. Dans la présente étude, nous intégrons dès lors la notion de motivation de service public (PSM) dans l’étude du partage des connaissances entre les agents de l’État. C’est en nous appuyant sur la théorie de la PSM que nous postulons que l’attirance pour la politique, l’attachement à l’intérêt général, la compassion et l’abnégation chez les agents de l’État peuvent les amener à partager les connaissances pour une raison sacrée : défendre l’intérêt général. C’est en se basant sur des données recueillies auprès de gestionnaires publics de niveau intermédiaire à Taïwan que les auteurs ont vérifié de manière empirique la question de savoir si la PSM était un prédicteur du partage des connaissances et nos hypothèses ont été clairement confirmées. La PSM ouvre dès lors une nouvelle voie aux chercheurs qui s’intéressent à l’étude du partage des connaissances dans le secteur public. Remarques à l’intention des praticiens En introduisant la PSM, la présente étude établit un lien entre partage des connaissances et administration publique. La fonction publique en tant que vocation amène les agents de l’État à partager leurs connaissances afin de faire progresser le savoir organisationnel et, partant, d’améliorer l’efficacité du service public. Par comparaison aux facteurs situationnels (comme l’utilisation des technologies de l’information et des récompenses), la PSM joue un rôle encore plus important dans la promotion du partage des connaissances si l’on en croit les résultats de notre recherche empirique. Il convient dès lors de prendre en considération la motivation altruiste et de la mettre en avant si l’on veut encourager le partage des connaissances dans le secteur public.
Anisotropic Sobolev Capacity with
Fractional Order
Authors: Xiao Jie , Ye Deping 
Published: December 2015

AbstractIn this paper, we introduce the anisotropic Sobolev capacity with fractional order and develop some basic properties for this new object. Applications to the theory of anisotropic fractional Sobolev spaces are provided. In particular, we give geometric characterizations for a nonnegative Radon measure μ that naturally induces an embedding of the anisotropic fractional Sobolev class into the μ-based-Lebesgue-space with 0 < β ≤ n. Also, we investigate the anisotropic fractional α-perimeter. Such a geometric quantity can be used to approximate the anisotropic Sobolev capacity with fractional order. Estimation on the constant in the related Minkowski inequality, which is asymptotically optimal as α →0+, will be provided.
Enhancing the Mesosystem for Adolescent Growth: Home-Based Parent Involvement and Guided Inquiry Activities for Parents and Children
Authors: Rillero Peter 
Published: December 2015

<p>Parent involvement in education is almost universally recognized as a positive influence on children, their academic performance, and attitudes toward school. While studies generally support these ideas, research on parental involvement is challenged by problems including a lack of agreement about what are the key aspects of parental involvement and limited research employing a theoretical model. Focusing on parental involvement as adults helping their children at home, this study had 101 sixth-grade students complete at-home guided-inquiry science activities with their parents. Levels of participation varied but were best when the activities aligned with the school curriculum and materials were readily available. Parents and students generally had positive attitudes toward the program, with parents more positive than students and female students slightly more positive than male students. Interview and survey results suggest most parents felt they helped their child learn science. Shortages of parent time and student procrastination were problems that were identified. Many parents reported learning more about their children. The majority of students indicated they would rather work on this type of homework with a parent than work alone. </p>
Effects of elastic anisotropy on acoustic-wave rectification
Authors: Tanaka Yukihiro , Nishiguchi Norihiko 
Published: December 2015

Abstract
We investigate numerically the rectification phenomena of bulk acoustic waves in an acoustic-wave rectifier composed of an elastically anisotropic material containing a periodic array of triangular holes. Paying special attention to the effects of elastic anisotropy on phonon mode coupling, we elucidate the rectification performance for quasi-longitudinal and slow transverse waves. We find that elastic anisotropy markedly improves acoustic-wave rectification in comparison with the system composed of isotropic materials, particularly for longitudinal acoustic waves.
