The blackmailer and the sodomite: Oscar Wilde on trial
Authors: Bristow Joseph
Published: December 2015

On 25 May 1895, Oscar Wilde went to jail after three humiliating trials – the first was Wilde’s failed suit against the Marquess of Queensberry who libelled him for ‘posing as a sodomite’; and the subsequent two involved the Crown’s prosecution of Wilde for committing acts of gross indecency with other men. This article revisits the trials by looking at sources that paint a rather different picture from the influential one that Ed Cohen and Alan Sinfield established in the 1990s. First, it shows that the prosecution persuaded the jury that it was far worse for Wilde to have committed sodomy on two young blackmailers (who also engaged in male prostitution) than the kinds of extortion of which, as they freely admitted, they were culpable. Secondly, the discussion suggests that it is unreasonable to claim that the trials defined the modern identity of the male homosexual.
An Examination of the Prior Use of E-Learning Within an Extended Technology Acceptance Model and the Factors That Influence the Behavioral Intention of Users to Use M-Learning
Authors: Abramson Jonathan , Dawson Maurice , Stevens Jeffery
Published: December 2015

The purpose of this empirical study was to test specific factors of behavioral intention to use m-learning in a community college setting using a modified technology acceptance model and antecedent factors suggested by the researcher’s review of the literature. In addition, the study’s purpose was to expand understanding of behavioral intention to use m-learning and to contribute to the growing body of research. This research model was based on relevant technology acceptance literature. The study examines the significance of “prior use of e-learning” and correlation with the behavioral intention to use m-learning. Existing models have looked at prior use of e-learning in other domains, but not specifically m-learning. Other models and studies have primarily looked at the prior use of e-learning variable as a moderating variable and not one that is directly related to attitude and behavioral intention. The study found that there is a relationship between prior use of e-learning and behavioral intention to use m-learning. This research direction was proposed by Lu and Viehland.

Bone marrow adipose tissue (MAT) accounts for up to 70% of bone marrow volume in healthy adults and increases further in clinical conditions of altered skeletal or metabolic function. Perhaps most strikingly, and in stark contrast to white adipose tissue, MAT has been found to increase during caloric restriction (CR) in humans and many other species. Hypoleptinemia may drive MAT expansion during CR but this has not been demonstrated conclusively. Indeed, MAT formation and function are poorly understood; hence, the physiological and pathological roles of MAT remain elusive. We recently revealed that MAT contributes to hyperadiponectinemia and systemic adaptations to CR. To further these observations, we have now performed CR studies in rabbits to determine whether CR affects adiponectin production by MAT. Moderate or extensive CR decreased bone mass, white adipose tissue mass, and circulating leptin but, surprisingly, did not cause hyperadiponectinemia or MAT expansion. Although this unexpected finding limited our subsequent MAT characterization, it demonstrates that during CR, bone loss can occur independently of MAT expansion; increased MAT may be required for hyperadiponectinemia; and hypoleptinemia is not sufficient for MAT expansion. We further investigated this relationship in mice. In females, CR increased MAT without decreasing circulating leptin, suggesting that hypoleptinemia is also not necessary for MAT expansion. Finally, circulating glucocorticoids increased during CR in mice but not rabbits, suggesting that glucocorticoids might drive MAT expansion during CR. These observations provide insights into the causes and consequences of CR-associated MAT expansion, knowledge with potential relevance to health and disease.
On the optimal stopping problems with monotone thresholds
Authors: Tamaki Mitsushi
Published: December 2015

As a class of optimal stopping problems with monotone thresholds, we define the candidate-choice problem (CCP) and derive two formulae for calculating its expected payoff. We apply the first formula to a particular CCP, i.e. the best-choice duration problem treated by Ferguson et al. (1992). The recall case is also examined as a comparison. We also derive the distribution of the stopping time of the CCP and find, as a by-product, that the best-choice problem has a remarkable feature in that the optimal probability of choosing the best is just the expected value of the (proportional) stopping time. The similarity between the best-choice duration problem and the best-choice problem with uniform freeze studied by Samuel-Cahn (1996) is recognized.
A note on the simulation of the Ginibre point process
Authors: Decreusefond Laurent , Flint Ian , Vergne Anais
Published: December 2015

The Ginibre point process (GPP) is one of the main examples of determinantal point processes on the complex plane. It is a recurring distribution of random matrix theory as well as a useful model in applied mathematics. In this paper we briefly overview the usual methods for the simulation of the GPP. Then we introduce a modified version of the GPP which constitutes a determinantal point process more suited for certain applications, and we detail its simulation. This modified GPP has the property of having a fixed number of points and having its support on a compact subset of the plane. See Decreusefond et al. (2013) for an extended version of this paper.
Poisson superposition processes
Authors: Crane Harry , Mccullagh Peter
Published: December 2015

Superposition is a mapping on point configurations that sends the n-tuple into the n-point configuration , counted with multiplicity. It is an additive set operation such that the superposition of a k-point configuration in is a kn-point configuration in . A Poisson superposition process is the superposition in of a Poisson process in the space of finite-length -valued sequences. From properties of Poisson processes as well as some algebraic properties of formal power series, we obtain an explicit expression for the Janossy measure of Poisson superposition processes, and we study their law under domain restriction. Examples of well-known Poisson superposition processes include compound Poisson, negative binomial, and permanental (boson) processes.
Randomisation and recursion methods for mixed-exponential Lévy models, with financial applications
Authors: Mijatović Aleksandar , Pistorius Martijn R. , Stolte Johannes
Published: December 2015

We develop a new Monte Carlo variance reduction method to estimate the expectation of two commonly encountered path-dependent functionals: first-passage times and occupation times of sets. The method is based on a recursive approximation of the first-passage time probability and expected occupation time of sets of a Lévy bridge process that relies in part on a randomisation of the time parameter. We establish this recursion for general Lévy processes and derive its explicit form for mixed-exponential jump-diffusions, a dense subclass (in the sense of weak approximation) of Lévy processes, which includes Brownian motion with drift, Kou's double-exponential model, and hyperexponential jump-diffusion models. We present a highly accurate numerical realisation and derive error estimates. By way of illustration the method is applied to the valuation of range accruals and barrier options under exponential Lévy models and Bates-type stochastic volatility models with exponential jumps. Compared with standard Monte Carlo methods, we find that the method is significantly more efficient.
On degenerate sums of m-dependent variables
Authors: Janson Svante
Published: December 2015

It is well known that the central limit theorem holds for partial sums of a stationary sequence (Xi) of m-dependent random variables with finite variance; however, the limit may be degenerate with variance 0 even if var(Xi) ≠ 0. We show that this happens only in the case when Xi – EXi = Yi – Yi–1 for an (m − 1)-dependent stationary sequence (Yi) with finite variance (a result implicit in earlier results), and give a version for block factors. This yields a simple criterion that is a sufficient condition for the limit not to be degenerate. Two applications to subtree counts in random trees are given.
Market Exposure and Endogenous Firm Volatility over the Business Cycle
Authors: Decker Ryan A. , D'Erasmo Pablo N. , Moscoso Boedo Hernan
Published: December 2015

We propose a theory of endogenous firm-level risk over the business cycle based on endogenous market exposure. Firms that reach a larger number of markets diversify market-specific demand shocks at a cost. The model is driven only by total factor productivity shocks and captures the observed countercyclity of firm-level risk. Using a panel of US firms we show that, consistent with our theoretical model, measures of market reach are procyclical, and the counter-cyclicality of firm-level risk is driven by those firms that adjust their market exposure, which are larger than those that do not.

Rational Inattention to News: The Perils of Forward Guidance
Authors: Gaballo Gaetano
Published: December 2015

This paper studies the social value of information about the future. In a stylized OLG model, agents need to forecast the future price level, they observe the current price and perceive with idiosyncratic noise the expectation announced by a more informed authority. When forward guidance communication is loose, the market becomes a main source of information about the future. Reliance on market information amplifies the impact of shocks on prices, which increases ex ante uncertainty and worsens agents' forecasting ability, harming social welfare. However, an appropriate policy can convert the perils of the announcement in opportunities. (JEL D83, E13, E52, E62, H63)
As diversas formas de ofertar valor para o cliente em sistemas de serviços
Authors: Scanfone Leila , Torres Junior Noel , Gosling Marlusa De Sevilha
Published: December 2015

A criação, a coprodução e a cocriação são modelos de oferta de valor para o cliente amplamente apresentados na literatura de operações, de marketing e de serviços. Contudo, existem lacunas quanto ao entendimento das especificidades de cada modelo e ao modo como as organizações podem aplicá-los. Posto isto, à luz das teorias de criação de valor, o objetivo deste trabalho é elucidar estes três modelos de oferta de valor por meio da apresentação, análise e discussão de três sistemas de serviços de informação sobre trânsito. Para tal, a partir da triangulação dos dados obtidos em sites, revistas, fóruns e blogs especializados e por meio de observação direta, buscou-se identificar como a oferta de valor é implementada em cada serviço estudado. Os resultados apontaram diferenças significativas entre os modelos quanto ao papel do cliente, às formas de interação e às possibilidades de realização de valor pelos os atores envolvidos no processo de serviço.

Published: December 2015

Os objetivos do estudo foram traduzir para o idioma português, realizar a adaptação transcultural e identificar as propriedades psicométricas do Behavioral Regulation in Exercise Questionnaire – Version 3 (BREQ-3) para uso em adultos brasileiros. O questionário original foi traduzido de acordo com recomendações internacionais. Um comitê de juízes foi formado para analisar as versões traduzidas do questionário. O comitê utilizou como critério de análise as equivalências semântica, idiomática, cultural e conceitual. A versão final do questionário traduzido foi administrada em uma amostra de 1041 adultos (55% homens) praticantes de exercício físico da área metropolitana da cidade de Londrina, Paraná com idades ≥ 18 anos. Para identificar as propriedades psicométricas iniciais foi realizada análise fatorial exploratória e, na sequência, análise fatorial confirmatória. Para análise da consistência interna de cada fator associado à motivação para a prática de exercício físico foi empregado coeficiente alfa de Cronbach. Após discretas modificações apontadas no processo de tradução, o comitê de juízes considerou que a versão para o idioma português do BREQ-3 apresentou equivalências semântica, idiomática, cultural e conceitual. A análise fatorial confirmou a estrutura de seis fatores originalmente proposta, mediante indicadores estatísticos equivalentes à χ2/gl = 1,91, ao GFI = 0,938, AGFI = 0,954 e RMSR = 0,059 (IC95% 0,051-0,069). O alfa de Cronbach apresentou coeficientes entre 0,67 e 0,87. Concluindo, a tradução, a adaptação transcultural e as qualidades psicométricas do BREQ-3 foram satisfatórias, o que viabiliza sua aplicação em futuros estudos no Brasil.
Gaussian Limits for a Fork-Join Network with Nonexchangeable Synchronization in Heavy Traffic
Authors: Lu Hongyuan , Pang Guodong
Published: December 2015

We study a fork-join network of stations with multiple servers and nonexchangeable synchronization in heavy traffic under the first-come-first- served (FCFS) discipline. Tasks are only synchronized if all the tasks associated with the same job are completed. Service times of parallel tasks of each job can be correlated. We jointly consider the number of tasks in each waiting buffer for synchronization with the number of tasks in each parallel service station and the number of synchronized jobs. We develop a new approach to show a functional central limit theorem for these processes in the quality-driven regime, under general assumptions on arrival and service processes. Specifically, we represent these processes as functionals of a sequential empirical process driven by the sequence of service vectors for each job’s parallel tasks. All of the limiting processes are functionals of two independent processes, i.e., the limiting arrival process and a generalized Kiefer process driven by the service vector of each job. We characterize the transient and stationary distributions of the limiting processes.
The Open-Ended Approach Framework
Authors: Munroe Lloyd
Published: December 2015

This paper describes a pedagogical framework that teachers can use to support students who are engaged in solving open-ended problems, by explaining how two Japanese expert teachers successfully apply open-ended problems in their mathematics class. The Open-Ended Approach (OPA) framework consists of two main sections: Understanding Mathematical Knowledge and Applying Mathematical Knowledge. The sections were cross-analyzed with students’ responses to provide a comprehensive analysis of how teachers use various techniques to support students. It is proposed that teachers can use this framework to create an environment that promotes learning with open-ended as well as other open problems in their mathematics classroom. The OPA framework can contribute to teacher education, the design of mathematics curricula and to educational research.
Patterns of Parental Involvement in Selected OECD Countries: Cross-National Analyses of PISA
Authors: Hartas Dimitra
Published: December 2015

Using data from the Programme for International Student Assessment (PISA), patterns of parental involvement were examined in selected OECD countries. The findings showed that, irrespective of educational qualifications, parents were frequently involved in their children’s learning at the start of primary school and at age 15. Cross-national analyses showed that a high percentage of parents were frequently involved in various ways with their children’s learning, with some OECD countries showing parental involvement to be very common. Less instrumental, more subtle forms of parental involvement such as parent-child conversations about topical social issues emerged as the strongest predictor for continuing parental literacy support at age 15. These findings have important implications for understanding patterns and forms of parenting and for guiding family policy to consider cultural, economic and educational explanations about the nature of parental involvement in children’s education.
A COMPARATIVE STUDY OF AHP, ELECTRE III & ELECTRE IV BY EQUAL OBJECTIVE & SHANNON’S ENTROPY OBJECTIVE & SAATY’S SUBJECTIVE CRITERIA WEIGHTING IN A PRIVATE SMALL HYDROPOWER PLANTS INVESTMENTS SELECTION PROBLEM
Authors: Saracoglu Burak Omer
Published: December 2015

Private small hydropower plant investments are more challenging than medium and large private hydropower plant investments when considering engineering analysis. One of the necessary tasks is the selection of the most appropriate private small hydropower investment amongst several alternatives. Brokerage, consultancy and private investor activities are a few examples of these kinds of real world activities. There are many multi-criteria decision making (MCDM) or multiple-criteria decision analysis (MCDA) methods, and different researchers prefer different methods This research study investigates three methods at once for the same problem: Analytic Hierarchy Process (AHP), Elimination and Choice Translating Reality (ELECTRE) III and ELECTRE IV. A comparative investigation is conducted on one simple unique selection model for all three methods. This unified model has seven objective factors (catchment area, project runoff, net head, flow rate, firm energy, secondary energy, investment cost). An additional comparison is also made on the criteria weighting amongst equal objective, Shannon’s Entropy objective and Saaty’s subjective criteria weighting. The simplistic unified model is structured in three levels. There are seven alternatives in the pre-development investment stage. The Super Decisions software and the ELECTRE III-IV software are implemented in this study. The pairwise comparisons of factors results in an inconsistency value of 0,09511 which is 7th in the Saaty's AHP weighting. The Shannon’s Entropy objective weighting represents a difference in the rate of the expert decision maker’s evaluations ranging between -67% and 671%. The equal weighting represents a rate change between -64% and 626%. Both approaches can't represent human judgments (here only one expert decision maker) well in this model. Fortunately, the same alternative (Alternative 3) ranks first. These findings promise that further studies on this subject can give some clues for the development of an autonomous computer based intelligent decision support system. Some observed pros and cons of these methods are also presented in this study. The observations and critical issues are presented during modeling, application, evaluation and analysis to help researchers, consultants, and readers in the small hydropower investments research and practical fields.

The portrayal of people with disabilities in Moroccan proverbs and jokes
Authors: Karimova Gulnara Z. , Sauers Daniel A. , Dakka Firdaousse
Published: December 2015

The depiction of physical impairments in popular culture reflects as well as moulds public perception and attitudes towards people with disabilities. The vast body of literature has been devoted to the analysis and documentation of images of disabilities on the Internet, literary fiction, films, advertisements and television programming in the western societies, but there has been less attention directed towards exploring the representation of people with disabilities in popular culture in nonwestern societies. This article explores how people with disabilities are portrayed in Moroccan popular culture, especially in jokes and proverbs. The study utilized faceto-face semi-structured interviews for collecting qualitative data regarding the status of people with disabilities in Moroccan popular culture. Convenience sampling was used in the research. Our findings suggest that the dominant themes of Moroccan popular culture replicate stereotypical images of people with impairment in western popular culture as ‘pitiable or pathetic’, ‘sinister or evil’, ‘laughable’, as a ‘burden’, ‘non-sexual’ and ‘unable to participate in daily life’. Although all these themes can be traced in the instances of Moroccan popular culture, the theme of sexuality of people with disabilities seems to prevail.

Published: December 2015

En este trabajo presentamos un panorama de la industria turística mexicana que incluye un análisis de las tendencias y la competitividad del sector en el contexto de la aplicación del Programa Nacional de Pueblos Mágicos. Se desarrolla un modelo econométrico con el fin de analizar el comportamiento del gasto de los visitantes a los Pueblos Mágicos del Estado de Guanajuato. Los coeficientes del modelo son estimados con una base de datos de la Secretaría de Turismo del Estado de Guanajuato. La información se generó a partir de una encuesta aplicada en los cinco Pueblos Mágicos de esa entidad en el año 2013. El modelo nos permite calcular elasticidades de los factores de impacto y generar niveles de referencia de gasto en diferentes escenarios. El modelo se plantea como una regresión log-lineal con variables explicativas que capturan características sociodemográficas y de hábitos de viaje. Tomando en cuenta los resultados del modelo, se discuten estrategias para estimular el crecimiento de la demanda turística en estos Pueblos Mágicos.

Published: December 2015

Anatomic alterations caused by incisal guide wear, even being small, cause the aspect of an aged smile. The objective of this clinical case is to report a highly conservative esthetical treatment, performed through the association of in-office bleaching and resin composite veneers. In-office bleaching was performed with 35% hydrogen peroxide, and in the following week minimal invasive resin composite veneers were implemented on upper incisors and canines. In the next appointment, finishing and polishing were performed with abrasive discs and silicon carbide brushes. The results were considered highly satisfactory, determining a younger aspect of the patient’s smile. Resin composite veneers are still an excellent alternative for esthetical reanatomization of anterior teeth, being capable to generate optimized results with low costs and time.

Published: December 2015

Objective: To evaluate the effects of 1% and 2.5% sodium hypochlorite (NaOCl) solutions at different periods of time on the composition of gutta-percha cones using Energy Dispersive Spectroscopy (EDS).Material and Methods: 110 master gutta-percha points were divided into 3 control groups and 8 experimental groups. Cones were immersed in 1% and 2.5% NaOCl for 30 minutes, 6, 12, 24 hours. Then, composition of the samples was analyzed by EDS. Statistical analysis was performed using the ANOVA and Tukey tests (p<0.05).Results: There was an increase of oxygen in experimental groups, and decrease of zinc when NaOCl was used, concentration and time-dependent.Conclusions: The disinfection with NaOCl solution causes alterations in the composition of gutta-percha cones. These modifications in gutta-percha structure might change important characteristics, increasing the risk of leakage and consequently failure of root canal treatment.

ABSTRACTObjective:This study evaluated the hardness and modulus of elasticityof the dentin bond interface using total-etch (Single Bond /SB) and self-etch (Clearfil SE Bond/CSEB) adhesives associated with Nd:YAG Laser irradiation through the unpolymerized adhesives.Material and Methods: The occlusal surfaces of 12 human third molars were ground until superficial dentin was exposed. A standardized circular cavity was performed on the occlusal surface. Specimens were sectioned in the mesio-distal direction, and the 24 hemi-crowns were divided into four groups: Group SB/Control - SB + polymerization; Group SB/Laser - SB + Nd:YAG laser (174.16J/cm2/60s/non-contact) + polymerization; Group CSEB/Control – CSEB + polymerization; Group CSEB/Laser - CSEB + Nd:YAG laser (174.16J/cm2/cm2/60s/non-contact) + polymerization. Composite were placed in the cavities and polymerized. The specimens were immersed in distilled water and stored in an oven at 37ºC for 24h and then submitted to nanoindentation in a Nano Indenter® XP appliance. Results: The results were submitted to ANOVA, Tukey’s test and Student's-t test (p < 0.05). Conclusão: It was concluded that the application of the Nd:YAG laser in both adhesive systems did not changed the hybrid layer hardness; however, it increases the modulus of elasticity in the hybrid layer for both adhesives tested and it maybe preserves the integrity of the adhesive interface and its durability. Clinical relevance: The application of Nd:YAG laser prior to photopolymerization of adhesive systems can increase the modulus of elasticity in the hybrid layer and may contribute to stress distribution in the adhesive interface during the polymerization preserving the integrity of the adhesive interface and its durability.

Published: December 2015

The temporomandibular joint (TMJ) plays an important role in the function of stomatognathic system. The acronym TMD – Temporomandibular disorder – is a general term for a series of signs and symptoms involving the masticatory muscles, TMJ, and associated structures. TMDs have a multifactorial etiology despite that many controversies still exist on this subject. Structural factors as trauma, malocclusion, systemic hypermobility, oral parafunctions, and emotional conditions (stress, anxiety, and depression) may trigger TMDs appearance. Objective: This study aimed to evaluate the signs and clinical symptoms of TMDs in patients treated at the School of Dentistry of the Institute of Science and Technology of São José dos Campos – UNESP - SP. Material and Methods: Fifty patients, both genders, aged between five and thirteen years were examined through muscle palpation and auscultation. Intra and extraoral examinations were performed, observing occlusion interference, denture type, protrusion or retrusion of the mandible, open bite or crossbite, edge-to-edge bite relation, midline shifts, limitation of mouth opening, and mandible shift during mouth opening and closing. Anamnesis comprised questions on the child’s habits and symptoms noticeable by the parents or legal guardians, information on the child’s personality and mood. Results: The obtained data were analyzed through percentage and qualitative analysis. Conclusion: It can be concluded that children exhibited signs and symptoms of TMDs, but TMDs presence cannot be affirmed in the studied sample; stress or altered behavior influenced on the presence of the signs and symptoms in the TMJ area Keywords Temporomandibular joint; Mixed dentition; Primary dentition; Temporomandibular joint dysfunction syndrome.

Published: December 2015

ABSTRACTObjective: This in vitro study aimed to compare the degree of root roughness in human teeth after using hand curettes, stainless steel, and diamond ultrasound tips. Material and Methods: The scaling was performed on the root surface of 36 human teeth previously standardized and randomly divided into three groups (n = 12). The roughness degree was measured with the aid of a rugosimeter, before and after the scaling, through readings perpendicular and parallel to the scaling direction. The statistical analysis comprised Wilcoxon and Kruskal-Wallis tests (p < 0.05). The qualitative and visual complementation of the results was performed by scanning electronic microscopy. Results: The scaling executed with hand curettes increased root roughness (before - Ra median = 0.1583 µm; after = 0.7783 µm; before - Rz median =1.667 µm; after = 7.350 µm). The degree of root roughness also increased when stainless steel ultrasound (before - Ra median = 0.1483 µm; after = 0.3933 µm; before- Rz median = 1.567 µm; after = 4.333 µm) and diamond tips were used (before - Ra median = 0.1800 µm; after = 2.457 µm; before - Rz median = 1.850 µm; after = 18.58 µm). Conclusion: The superficial roughness significantly increased in all groups.  The scaling with diamond tips promoted the greatest root roughness than hand curettes and ultrasound tips. Keywords: Dental biofilm; Dental scaling; Periodontics; Superficial roughness.

Published: December 2015

The cultivation in greenhouse and containers culminated with the necessity to use substrates with formulations as well as distinguished chemical and physical characteristics, the last ones assuming a key role in cultivation of horticultural plants. The aim of this study is to present results of physical and chemical analyses of substrates forwarded to an commercial laboratory (Laboratório de Substratos para Plantas - UFRGS) for the last three years, aiming to establishing a panorama of the substrates area and comparing them with reference values cited in the literature. In this period were performed 307 physical and 479 chemical analyses, which were the basis for this study. Physical analyses performed were the density in dry basis and the water retention curve (total porosity, air space, available water and remaining water). Chemical analyses were the electrical conductivity (EC) and the pH. The main results concerning physical characteristics, demonstrate that the substrates present wide range of density in dry basis and may be used for different sized containers; however most substrates analyzed is out of ideal range for the other physical characteristics of the substrate. For the chemical characteristic the substrates in cultivation in southern Brazil are mostly alkaline and the electrical conductivity of the substrates in cultivation is very diverse, with considerable number of samples above the recommended.
Soberanía nacional y soberanías provinciales ante la Corte Suprema de Justicia. Argentina, siglo XIX
Authors: Zimmermann Eduardo
Published: December 2015

A poco de instaladas las nuevas instituciones de la justicia federal (Corte Suprema de Justicia de la Nación y juzgados de sección en las provincias) durante la presidencia de Bartolomé Mitre, se planteó en 1865 un caso judicial que volvería a poner en disputa las relaciones entre la Nación y las provincias, entre las fuerzasde la centralización y la descentralización política, entre concepciones de soberanía nacional y soberanías provinciales, que habían chocado una y otra vez desde la primera mitad del siglo. Esa disputa alimentaba las distintas interpretaciones que se hacían del régimen federal que, aparentemente estabilizado tras la reforma constitucional de 1860, continuaría siendo desafiado por los levantamientos provinciales a lo largo de esa década y la siguiente.

J Strength Cond Res 30(8): 2361–2368, 2016—The purpose of this study was to perform a systematic review and meta-analysis of controlled trials to determine the effect of strength training programs on the running economy (RE) of high-level middle- and long-distance runners. Four electronic databases were searched in September 2015 (PubMed, SPORTDiscus, MEDLINE, and CINAHL) for original research articles. After analyzing 699 resultant original articles, studies were included if the following criteria were met: (a) participants were competitive middle- or long-distance runners; (b) participants had a V̇o
2max >60 ml·kg−1·min−1; (c) studies were controlled trials published in peer-reviewed journals; (d) studies analyzed the effects of strength training programs with a duration greater than 4 weeks; and (e) RE was measured before and after the strength training intervention. Five studies met the inclusion criteria, resulting in a total sample size of 93 competitive, high-level middle- and long-distance runners. Four of the 5 included studies used low to moderate training intensities (40–70% one repetition maximum), and all of them used low to moderate training volume (2–4 resistance lower-body exercises plus up to 200 jumps and 5–10 short sprints) 2–3 times per week for 8–12 weeks. The meta-analyzed effect of strength training programs on RE in high-level middle- and long-distance runners showed a large, beneficial effect (standardized mean difference [95% confidence interval] = −1.42 [−2.23 to −0.60]). In conclusion, a strength training program including low to high intensity resistance exercises and plyometric exercises performed 2–3 times per week for 8–12 weeks is an appropriate strategy to improve RE in highly trained middle- and long-distance runners.

Focusing on the critical solution of problematic human resource management situations (staff retention, outlook predictions, wages justification, etc.), nowadays agricultural company managers should perceive the antecedents of normatively committed man power as well as their hierarchical dependence. The mentioned hierarchy describes the nature and conditions of employee’s formal commitment to an organization; besides guarantees the validity of the appropriate leadership logic. Scientific problem statement – how to hierarchically classify the antecedents of an employee’s normative commitment. The research objective declared – practicing the Decision trees technique to reveal hierarchical dependence (according to the strongly normatively committed groups of respondents). The research methods applied: scientific literature analysis, synthesis and generalization, as well as exploratory and confirmatory analysis. The latter method identified the hierarchical interactions of the normatively committed man power antecedents. In this article outlined hierarchical interactions among antecedents of an employee’s normative commitment undoubtedly reveal organizational behaviors of individuals, therefore taking into account the strongest motivators of formal commitment are also recommended to be involved into human resource management practice of agricultural companies.

An annotated checklist of the endemic Carabidae (Coleoptera) of Egypt
Authors: Abdel-Dayem Mahmoud S.
Published: December 2015

Endemic species are usually not very widespread in their distribution, but are only found in a particular region and nowhere else in the world. Because of this, they are of great conservation concern. A checklist of the endemic carabid beetles of Egypt was compiled and updated from published and unpublished records including long-term surveys. As far as can be ascertained, there are 39 valid carabid species and subspecies from 28 genera that are endemic to Egypt including Sinai. These represent about 16.3% of the total carabid fauna recorded from the country, and belong to five subfamilies: Brachininae, Cicindelinae, Harpalinae, Scaritinae, and Trechinae. I provide notes about type localities, depositories and distribution.
Aves, Thraupidae, Indigo Flowerpiercer Diglossa indigotica (Sclater, 1856): New country records, natural history notes, and occurrence in northwest Ecuador
Authors: Solano-Ugalde Alejandro , Brinkhuizen Dušan M.
Published: December 2015

Only old records of the Indigo Flowerpiercer Diglossa indigotica are known from Pichincha province, Ecuador. Here we report 26 sight records of this rare species at a new locality, the Bosque Protector Mashpi. These novel records confirm that the species is resident, and represent the first evidence of breeding in the country. The species seems to have a habitat preference for patches of short Ericaceous growth, but occurs locally in mossy cloud forest, typically found in low densities. Adults sang throughout the year, usually from canopy but also from inside short Ericaceous growth. The discovery of this site posses a great opportunity to further studies of this little known Choco endemic species.

The control problem of a class of hyper-redundant arms with continuum elements, with boundary measuring and control is discussed. First, the dynamic model of the continuum arm is presented. The measuring systems are based on the film sensors that are placed at the terminal sub-regions of the arm. The observers are proposed in order to reconstruct the full state of the arm. A back-stepping method is used to design a boundary control algorithm. Numerical simulations of the arm motion toward an imposed position are presented. An experimental platform shows the effectiveness of the proposed methods.
An Algorithm for Customer Order Fulfillment in a Make-to-Stock Manufacturing System

Published: December 2015

In the competitive environment, many manufacturers are increasingly focusing on designing the systems that help them to manage variable demand and supply situations. Dynamic allocation of demands is very important in case of customer order allocations. Order promising and allocation can be based on the simple sequence that enables a manufacturing company to receive orders unless there are some other priority orders. Manufacturing company can also manage allocations of supply to key customers and channels, thereby ensuring that they can meet contractual agreements and service levels in the priority that yields better profit. This paper will focus on a Maketo- Stock order fulfillment system facing random demand with random orders from different classes of customers. Available-to-promise (ATP) calculating from master production schedule (MPS) exhibits availability of finished goods that can be used to support customer order allocation. This order allocation system is adapted in MTS (make-to-stock) production model and all orders are treated according to maximization of customer service policy. It allows incoming purchase orders as well as existing inventory on hand to be selected and allocated to customer sale orders and back orders. The system then automatically allocates the available stock to the selected sales orders. We developed an integrated system for allocation of inventory in anticipation of customer service of high priority customers and for order promising in real-time. Our research exhibits three distinct features:
(1) We explicitly classified customers in groups based on target customer service level;
(2) We defined higher level of customer selection directly defined according to company strategy to develop small and medium customers;
(3) We considered backorders that manufacturing company has to fulfill in order to maximize overall customer service for certain customers.
The benefits of a granular interface over pyritic subgrade
Authors: Czerewko Mourice A. , Cross Stephen A.
Published: December 2015

Construction and improvement of the arterial highway infrastructure in the UK often encounters areas of pyritic ground. Pyrite bearing subgrades, particularly mudrocks, have a strong likelihood to be problematic due to oxidation producing both volumetric and mineralogical changes in the host deposit. Consideration of the possible adverse implications to the highway tends to be overlooked without exploring the possibilities and consequences of subgrade and earthwork material degradation. Protection to road pavements may be best achieved by the inclusion of a granular construction interface separating the pavement construction from the potentially deleterious underlying pyritic subgrade. Traditional road construction relied on an empirical approach for foundation design with inclusion of granular capping over low-strength subgrades as protection. Revision to the guidance in the last decade has introduced a performance-based approach which leaves the decision to include a granular capping with the designer. Therefore, if pyritic subgrades were present, the absence of a granular separator layer may expose the road pavement and associated structures to the consequences of ground movements and aggressive ground conditions. This paper presents three road construction cases involving pyritic mudstone subgrades to demonstrate the benefits of inert granular construction interfaces in achieving road pavement integrity.
