Dimensioning a Call Center: Simulation or Queue Theory?
Authors: Bouzada Marco Aurélio Carino
Published: August 2018

The objective of this paper is to establish a dichotomy - opposing analytical methods (such as Queue Theory) to experimental methods (such as Simulation) and discussing their adequateness to complex operations - set up in the matter of dimensioning the handling capacity of a large brazilian call centers company. The literature related to the application of such methods at call centers is reviewed, and the way the question is treated nowadays by the company is described. Then an experimental approach is suggested to be implemented as an alternative methodology to deal with the issue, instead of the analytical method in use. The results obtained are used to justify the adequacy of the experimental approach to the modern call centers operation, as long as it is possible to have the model closer to reality. The main implication points to a better understanding of the operation achieved with the new approach

Authors: Graeml Alexandre Reis , Balbinot Zandra , Csillag João Mário
Published: August 2018

This paper presents the results of a study about the impact of the Internet and other information technologies on supply chain management, as perceived by managers in the field. Two almost identical surveys were applied to 105 Brazilian manufacturing companies, three years apart from one another, aiming to depict changes on managers' perceptions over time. Answers to the questions were organized and presented in bar graphs segmented based on the year and the companies' size. Several analyses were then possible, which helped to understand how the scenario evolved over time and to depict trends for the future.Answers to the questions were organized and presented in bar graphs segmented by year and company size. Several analyses were possible, which enlightened us as to how the scenario evolved from 2003/2004 to 2006/2007 and provided data with which to project trends for the future
Establishing the relationship between logistics complexity and supply chain objectives and decision areas in large companies operating in Brazil
Authors: Wanke Peter , Correa Henrique Luiz , Hijjar Maria Fernanda
Published: August 2018

This paper reports an attempt to explore the relationships between logistics complexity and supply chain management (SCM) objectives and decision areas in large manufacturing companies operating in Brazil. Literature review is conducted, followed by survey research data (using a sample of 108 large companies operating in Brazil) analysis using cluster analysis, factor analysis and binary logistic regression. Results suggest that the level of logistics complexity of companies is a driver of management choices in supply chain objectives and decision areas, confirming our initial proposition that a contingency approach for supply chain management would be more appropriate than the "best practice" one. At the end of the article some further conclusions are drawn and opportunities for further research are discussed.

Authors: Martins Ricardo Silveira , Xavier Wescley Silva , De Souza Filho Osmar Vieira , Martins Guilherme Silveira
Published: August 2018

The research reported in this paper, looks at the internal processes of Brazilian small and medium-sized enterprises (SMEs) concerning the transport decision. SME represent over 99% of the formal enterprises in Brazil. The sample size was 400 industrial companies (with up to 100 employees) of Brazilian manufacturing sector. The results indicated that shippers do not use transportation as an opportunity to create competitive advantages. In addition, to get the needed services, Brazilian SMEs tend to buy transport services, readily available, without concerns for future transactions and more stringent and systematic criteria for the selection and evaluation of the service.
Supply chain mapping initiatives in the Brazilian automotive industry: challenges and opportunities
Authors: Miyake Dario Ikuo , Torres Junior Alvair Silveira , Favaro Cleber
Published: August 2018

Leading manufacturers that have advanced in the streamlining of internal processes are realising that the accomplishment of further performance gains implies stretching the deployment of process improvement efforts beyond their boundaries. In this context, there is a growing interest in extending mapping activities to inter-plant and inter-firm levels. However, research on the conditions under which such an initiative has actually been tackled in industry is still incipient. Based on multiple-case study method, this paper discusses some supply chain (SC) mapping initiatives undertaken in the Brazilian automotive industry. The study examines the major motivations, difficulties, and outcomes observed in the cases, as well as the methodological approach adopted in their realisation. The cases reveal that despite its intrinsic complexity, the SC mapping process provides invaluable opportunities to strengthen the SC capabilities. However, its adoption as a formal management method with strategic implications will depend on clearer understanding of its relevance and potentials.

Authors: Rashed Chourdhury Abul Anam , Azeem Abdullahil , Halim Zaheed
Published: August 2018

Supply chain management emphasizes the overall and long-term benefit of all parties on the chain through cooperation and information sharing. Recently, information sharing is attaining the concentration of the researchers. Majority of the previous work is on the individual effect of information and knowledge sharing on performance. This paper aims to focus on the combined consequence of information and knowledge sharing on supplier's operational performance through supplier-buyer relationship. A conceptual model was formulated based on previous literature. A questionnaire based survey was performed. Data from 30 Bangladeshi Readymade Garments Industry were collected through interview and mail survey. The content validity, construct validity, and reliability are tested. Path Analysis is performed for the identification of the validity of the model. The findings show that information sharing is a prerequisite for knowledge sharing and the close supplier-buyer relationship is a vital factor for escalating the supplier's operational performance.
Measuring Logistics Performance: the Effectiveness of Mmog/Le as Perceived by Suppliers in the Automotive Industry
Authors: Graeml Alexandre Reis , Peinado Jurandir
Published: August 2018

In spite of logistics having grown in importance lately, which included the discussion of concepts such as integrated logistics and supply chain management in the business agenda, little has been discussed about how to measure logistics performance. This paper analyzes the perception of logistics professionals about the effectiveness of MMOG/LE (Materials Management Operating Guideline/Logistics Evaluation), which is a set of recommendations regarding logistics and materials management that was created by the automotive industry to be used by those comprising its supply chain. The respondents, who were naturally all from the automotive industry (they were suppliers of large vehicle assemblers with industrial plants located in Brazil), had been previously trained on this logistics performance evaluation tool in order to implement it in their organizations. They filled in an email survey with Likert scale questions, early in 2008. Among other findings of the research, it was noticed that the impact of the MMOG/LE recommendation is stronger with respect to activities that had not been previously addressed by quality norms and recommendations. Most respondents also considered that their organizations were already efficient in integrating their activities with their customers (car assemblers) but rarely with their suppliers, which was acknowledged to be the bottleneck of their logistics systems.
Quality Certification Label: the Case of the Pioneering Indication of Origin in Brazil
Authors: Schmidt Carla Maria , Saes Maria Sylvia Macchione
Published: August 2018

In the region of Vale dos Vinhedos, RS it is inserted a network formed by wineries, grape growers, hotels and restaurants. Collective actions occur in the network, standing out the Indication of Origin Label of fine wines. This certification of quality affected several actors, since the consequences of the label for the different actors involved are unknown. Thus, in this study, the implications of the certification for the grape growers and wineries were identified, through interviews and questionnaires. The main results point to a scenario of value creation in the viticulture network. The label has a positive impact on the sales of fine and common wines of the wineries. It was also identified that the certification shows a positive influence on the income of the region's producers. The research demonstrates that the profits existent in networks overcome the risks and costs of such collective systems.
Optimal product/customer mix selection as a strategic tool for cross-functional integration
Authors: De Figueiredo João Neiva , Mayerle Sergio Fernando , Donato Felipe Simas
Published: August 2018

Cross-functional integration is a necessity as operations become ever more important for the formulation and implementation of overall company strategy. Despite the abundance of theoretical studies extolling the advisability of smooth intra-company interfacing, the operations strategy literature has not been as prolific regarding tools to increase this desired integration. This paper develops an uncomplicated multi-period analytical model that helps increase coordination of the engineering, purchasing, marketing, and sales areas among themselves and with manufacturing by focusing on the overall company objective of maximizing contribution to profits. The paper begins describing the theoretical underpinnings of production and operations processes as they relate to the strategy of the firm, presents the model, and then expands its scope to include interfaces with other functional areas of the firm. The methodology is based on a two-stage multi-period optimization model for aggregate production planning encompassing component supply management and final assembly. This methodology expands the concept of Sales and Operations Planning (S&OP) through a linear programming model that uses cost and profit contribution data to select the optimal product and customer mix. The sensitivity of results to costing and pricing data leads to increased cross-functional coordination. An illustrative application improving the medium-term operations strategy of a Brazilian OEM manufacturer is presented.

Authors: Martins Ricardo Silveira , De Souza Filho Osmar Vieira , Pereira Susana Carla Farias , Di Serio Luiz Carlos
Published: August 2018

The research objective is verifying the strategic alignment of supply practices between automakers and suppliers in the Brazilian automotive supply chains. It makes an exploratory-descriptive study of objectives, using quantitative/qualitative procedures and inductive reasoning. The concept used for analyzing the alignment of practices was based on Vachon et al. (2009). The main conclusion of this study is that suppliers and automakers seem to align their supply strategy, giving support to a desirable situation of single chain project. The subsidiary conclusion is the lack of relationship between intensity of the link and misalignment in these companies. The main contributions are the analysis of the relationship established in tiers that are the furthest removed from the focal companies; identification of practices that support the expansion of a new model of arrangements implemented by automakers in Brazil; and understanding of the processes that companies have adopted in order to manage their supply chains and the implications of these activities for the competitiveness of both the company and the supply chain as a whole.
Analysis of CSR in Midsize Retail: Application of the Quazi Aand O’brien Model
Authors: Filgueiras João Luis Melo , De Oliveira Marcelo Gonçalves , Neto Francisco César de Castro , Da Silva Filho José Carlos Lazaro
Published: August 2018

Originally a response to environmental pressures, the paradigm of corporate social responsibility (CSR) has become a socioenvironmental strategy. The study was centered around the question: according to the two-dimensional model of Quazi and O’Brien, what is the socioenvironmental perspective of the midsize retail supermarket industry in Fortaleza? The study design was exploratory and quantitative. Information was gathered from the managers of 14 midsize supermarkets in Fortaleza using a closed structured questionnaire containing 25 items based on the model of Quazi and O’Brien. Using exploratory factorial analysis, the sampled companies were found to be clustered in the “modern view” quadrant of the model.
Optimality Theory, Language Typology, and Universalist Metrics
Authors: Russom Geoffrey
Published: August 2018

In Russom (2011), I defended a universalist hypothesis that the constituents of poetic form are abstracted from natural linguistic constituents: metrical positions from phonological constituents, usually syllables; metrical feet from morphological constituents, usually words; and metrical lines from syntactic constituents, usually sentences. An important corollary to this hypothesis is that norms for realization of a metrical constituent are based on norms for the corresponding linguistic constituent. Optimality Theory provides a universalist account of relevant linguistic norms and deals effectively with situations in which norms conflict, employing ranked violable rules. Language Typology provides a universalist account of relevant syntactic norms. In this paper I integrate these independently grounded methodologies and use them to explain the distribution of constituents within the line, identifying a variety of important facts that seem to have escaped previous notice. Universalist claims are tested against meters from each of the major language types: subject-verb-object (SVO), subject-object-verb (SOV) and verb-subject-object (VSO). My findings are incompatible with the claim that “lines are sequences of syllables, rather than of words or phrases” (Fabb, Halle 2008: 11).
Attributing John Marston’s Marginal Plays
Authors: Freebury-Jones Darren , Tarlinskaja Marina , Dahl Marcus
Published: August 2018

John Marston (c. 1576–1634) was a dramatist of the Elizabethan and Jacobean periods, known for his satirical wit and literary feuds with Ben Jonson. His dramatic corpus consists of nine plays of uncontested authorship. This article investigates four additional plays of uncertain authorship which have been associated with Marston: Lust’s Dominion; Histriomastix; The Family of Love; and The Insatiate Countess. The internal evidence for Marston’s hand in these four texts is examined and an analysis made of the potential divisions of authorship. The essay provides a survey of Marston’s individual style by testing vocabulary; prosody; collocations of thought and language; and versification habits within both his acknowledged plays and the contested texts, in comparison to plays written by other authorship candidates.
Testing by Competitors in Enforcement of Product Standards
Authors: Plambeck Erica L. , Taylor Terry A.
Published: August 2018

Firms have an incentive to test competitors’ products to reveal violations of safety and environmental standards, in order to have competitors’ products blocked from sale. This paper shows that testing by a regulator crowds out testing by competitors, and can reduce firms’ efforts to comply with the product standard. Relying on competitor testing (i.e., having the regulator test only to verify evidence of violations provided by competitors) is most effective in large or concentrated markets in which firms have strong brands and high quality, and for standards that are highly valued by consumers. Under those conditions, firms tend to test competitors’ products and exert high compliance effort. Conversely, unless compliance is highly valued by consumers, a firm with low quality does not draw testing from competitors, and so does not comply. Enforcing a product standard through competitor testing encourages entry by such low-quality, noncompliant firms and can reduce quality investment by incumbents. Stripping offending products of labels (such as “Energy Star”), instead of blocking them from the market, eliminates the problem of entry by low-quality, noncompliant firms, but may reduce incumbents’ compliance efforts.

Residual hip dysplasia: Is there a place for hip shelf operation?
Authors: Terjesen T.
Published: August 2018

Purpose

After modern acetabular osteotomies were introduced, hip shelf operations have become much less commonly used. The aims of this study were to assess the short-term and long-term outcome of a modified Spitzy shelf procedure and to compare the results with those of periacetabular osteotomy (PAO).

Methods

In all, 44 patients (55 hips) with developmental dysplasia of the hip and residual dysplasia had a modified Spitzy shelf operation. Mean age at surgery was 13.2 years (8 to 22). Indication for surgery was a centre-edge angle < 20° with or without hip pain. Outcome was evaluated using duration of painless period and survival analysis with conversion to total hip arthroplasty (THA) as endpoints.

Results

Preoperative hip pain was present in 46% of the hips and was more common in patients ≥ 12 years at surgery (p < 0.001). One year postoperatively, 93% of the hips were painless. Analysis of pain in hips with more than ten years follow-up showed a mean postoperative painless period of 20.0 years (0 to 49). In all, 44 hips (80%) had undergone THA at a mean patient age of 50.5 years (37 to 63). Mean survival of the shelf procedure (time from operation to THA) was 39.3 years (21 to 55).

Conclusions

The Spitzy operation had good short and long-term effects on hip pain and a 30-year survival (no THA) of 72% of the hips. These results compare favourably with those of PAO and indicate that there is still a place for the shelf procedure in older children and young adults.
Proximal femoral growth disturbance in developmental dysplasia of the hip: What do we know?
Authors: Weinstein S. L. , Dolan L. A.
Published: August 2018

Background

Proximal femoral growth disturbance (PFGD) can be the most devastating complication of the treatment of development dysplasia of the hip. The reported incidence ranges from 0% to 73%. The condition involves varying degrees of growth disturbances of the femoral capital epiphysis, the physeal plate or both.

Purpose

This manuscript will discuss normal growth and development of the hip, the blood supply to the upper end of the femur, pathological and radiographic changes, classifications used to describe PFGD and, most importantly, the potential causes of these growth disturbances and the authors’ strategies for avoiding PFGD.
Closed reduction in late-detected developmental dysplasia of the hip: Indications, results and complications
Authors: Wicart P. , Seringe R. , Glorion C. , Brassac A. , Rampal V.
Published: August 2018

Purpose

The aim of the study was a review of the literature in order to evaluate the results and complications of closed reduction in late-detected developmental dysplasia of the hip (DDH).

Methods

This study consisted of an analysis of the literature relative to late-detected DDH treatment options considering hip congruency, rates of re-dislocation and of avascular necrosis.

Results

Gradual closed reduction (Petit-Morel method) appears to be an effective method concerning joint congruency restitution. Dislocation relapse and avascular necrosis are more efficiently prevented with closed versus open reduction. The tendency for spontaneous correction of acetabular dysplasia decreases if closed reduction is performed after 18 months of age. Patient age at the beginning of traction should be considered for the prognosis, with a lower rate of satisfactory results showing after the age of 3 years.

Conclusion

In our opinion, the Petit-Morel method is a suitable treatment option for children aged between six months and three years with idiopathic DDH.
Correlation and regression analysis of the body measurements of the Doro Ncanga Buffalo (Bubalus bubalis) reared extensively in the Savanna of Mount Tambora Dompu Regency, Indonesia

Published: August 2018

The objectives of the present study were examined the correlation and regression of body measurements of the Doro Ncanga buffaloes in the Savanna of Mount Tambora Dompu Regency, Indonesia. A total of 339 animals were used in this study. In female, body weight (BW) was found to be significantly (p<0.05) correlated with body length (BL), the degree of correlation increased from 0-6 (r=0.319) to 13-24 months (r=0.394), thereafter decreased at >36 months (r=0.160). The BW was not significantly correlated with height at wither (HW) for all 5 age groups. However, BW and heart girth (HG) were highly correlated (p<0.01) between age groups 0-6 (r=0.967) and >36 months (r=0.978). The BL was significantly (p<0.01) correlated with HW from 0-6 to 13-24 months of age, except for 25-36 months of age. The correlation between BL and HG was highly significant (p<0.01) at 0-6 (r=0.427) and 13-24 (0.371) months of age, then decreased with the increase of age. The HW had no strong correlation with HG  at all groups. Regression model of BW changes with HG was predictable with R2 values ranged from 0.896 to 0.957. In male, BW had a strong correlations with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). The BL and HW were not highly correlated with BW at all groups. However, BW was significantly (p<0.01) correlated with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). Their R2 values were 0.958 and 0.945, respectively. A highly significant (p<0.01) correlations were also observed between BL and HW for age groups 0-6 months (r=0.677)and 7-12 months (0.462). The  R2 values were 0.458 and 0.214 for the two different age groups, respectively. The estimates of coefficient of determinations and predictive equations show that HG alone could be used to predict BW of female and male Doro Ncanga buffalo at different age groups.
Effectiveness of poultry litter amendments on bacterial survival and Eimeria oocyst sporulation
Authors: Soliman Essam S. , Sallam Nahla H. , Abouelhassan Eman M.
Published: August 2018

Aim: Broilers' optimum performance in response to their genetic potential depends on litter environment which is ideal for bacterial survival and coccidian oocyst sporulation. An in vitro evaluation was conducted for the effectiveness of superphosphate, meta-bisulfide, and charcoal litter amendments in minimizing Escherichia coli O157:H7 and Salmonella Typhimurium survival, Eimeria oocyst count, and sporulation.

Materials and Methods: Three groups of 16 litter trays were prepared and inoculated with E. coli O157:H7, S. Typhimurium, and Eimeria non-sporulated oocyst. A set of four trays in each group was designed for each one of the chemical amendments. A total of 720 litter samples were collected and examined for bacterial counts, Eimeria oocyst count, and sporulation during the experimental period (35 days).

Results: Litter moisture and pH revealed a highly significant (p<0.001) reduction in all treated litter trays compared to control. Total bacterial count (TBC), total Enterobacteriaceae count, and S. Typhimurium count showed a highly significant (p<0.001) reduction in meta-bisulfide-treated trays compared to other amendments and positive control. Meanwhile, Eimeria oocyst count and sporulation revealed a highly significant (p<0.001) reduction in superphosphate, meta-bisulfide, and charcoal-treated trays, respectively. Temperature revealed a highly significant (p<0.001) weak positive correlation with pH of all inoculated trays, a highly significant (p<0.001) weak negative correlation with moisture percentage of E. coli O157:H7 and S. Typhimurium inoculated trays, and a highly significant (p<0.001) weak negative correlation with TBC. Meanwhile, relative humidity revealed significant (p≤0.005) weak positive correlation with moisture percentage of E. coli O157:H7 inoculated trays.

Conclusion: The study concluded that regular usage with periodical reapplication of litter amendments as meta-bisulfide or superphosphate in poultry farms is one of the indispensable managemental and preventive measures for minimizing bacterial survival and inhibiting Eimeria oocyst maturation and sporulation.

Keywords: charcoal, Eimeria, Escherichia coli, litter, meta-bisulfide, Salmonella, superphosphate.
Thyrotoxic hepatitis
Authors: Pikulev Dmitrij V. , Klemenov Aleksej V.
Published: August 2018

In most cases, liver pathology in hyperthyroidism is confined to asymptomatic changes in laboratory indices, while clinical signs are much rarer. Three clinical variants of liver pathology in patients with hyperthyroidism can be differentiated: drug-induced hepatitis that develop in response to administration of thyrostatic agents (mainly propylthiouracil); concomitant autoimmune liver diseases (autoimmune hepatitis, primary biliary cirrhosis), and hepatopathies as a direct manifestation of thyrotoxicosis (thyrotoxic hepatitis). Thyrotoxic hepatitis is a rare condition difficult to diagnose. The variety of etiological factor of liver pathology in hyperthyroidism, universal clinical symptoms, and the lack of specific histological markers make it difficult to make a correct diagnosis.
A clinical case of Graves’ disease complicated with severe thyrotoxic hepatitis, the edema-ascites syndrome and hyperbilirubinemia is reported. The patient was diagnosed with thyrotoxic hepatitis after all other reasons for liver pathology have been ruled out. The concomitant thyrogenic myocardiodystrophy, cardiomegaly and atrial fibrillation required ruling out the diagnosis of cardiogenic liver injury and made diagnosing more difficult. Normalization of the thyroid status in patients receiving mercazolyl therapy was accompanied by alleviation of clinical symptoms of hepatitis and the positive dynamics of the indices of liver function tests.
A brief review of the data on clinical variants and mechanisms of liver injury in patients with thyrotoxicosis is presented.

Differentiable Processing of Objects, Associations, and Scenes within the Hippocampus
Authors: Dalton Marshall A. , Zeidman Peter , McCormick Cornelia , Maguire Eleanor A.
Published: August 2018

The hippocampus is known to be important for a range of cognitive functions, including episodic memory, spatial navigation, and thinking about the future. However, researchers have found it difficult to agree on the exact nature of this brain structure's contribution to cognition. Some theories emphasize the role of the hippocampus in associative processes. Another theory proposes that scene construction is its primary role. To directly compare these accounts of hippocampal function in human males and females, we devised a novel mental imagery paradigm where different tasks were closely matched for associative processing and mental construction, but either did or did not evoke scene representations, and we combined this with high-resolution functional MRI. The results were striking in showing that different parts of the hippocampus, along with distinct cortical regions, were recruited for scene construction or nonscene-evoking associative processing. The contrasting patterns of neural engagement could not be accounted for by differences in eye movements, mnemonic processing, or the phenomenology of mental imagery. These results inform conceptual debates in the field by showing that the hippocampus does not seem to favor one type of process over another; it is not a story of exclusivity. Rather, there may be different circuits within the hippocampus, each associated with different cortical inputs, which become engaged depending on the nature of the stimuli and the task at hand. Overall, our findings emphasize the importance of considering the hippocampus as a heterogeneous structure, and that a focus on characterizing how specific portions of the hippocampus interact with other brain regions may promote a better understanding of its role in cognition.

Mixed problem for the singular partial differential equation of parabolic type
Authors: Makhnei O.V.
Published: August 2018

The scheme for solving of a mixed problem is proposed for a differential equation \[a(x)\frac{\partial T}{\partial \tau}= \frac{\partial}{\partial x} \left(c(x)\frac{\partial T}{\partial x}\right) -g(x)\, T\] with coefficients $a(x)$, $g(x)$ that are the generalized derivatives of functions of bounded variation, $c(x)>0$, $c^{-1}(x)$ is a bounded and measurable function. The boundary and initial conditions have the form $$p_{1}T(0,\tau)+p_{2}T^{[1]}_x (0,\tau)= \psi_1(\tau), q_{1}T(l,\tau)+q_{2}T^{[1]}_x (l,\tau)= \psi_2(\tau), $$ $$T(x,0)=\varphi(x), $$ where $p_1 p_2\leq 0$, $q_1 q_2\geq 0$ and by $T^{[1]}_x (x,\tau)$ we denote the quasiderivative $c(x)\frac{\partial T}{\partial x}$. A solution of this problem seek by the reduction method in the form of sum of two functions $T(x,\tau)=u(x,\tau)+v(x,\tau)$. This method allows to reduce solving of proposed problem to solving of two problems: a quasistationary boundary problem with initial and boundary conditions for the search of the function $u(x,\tau)$ and a mixed problem with zero boundary conditions for some inhomogeneous equation with an unknown function $v(x,\tau)$. The first of these problems is solved through the introduction of the quasiderivative. Fourier method and expansions in eigenfunctions of some boundary value problem for the second-order quasidifferential equation $\big(c(x)X'(x)\big)' -g(x)X(x)+ \omega a(x)X(x)=0$ are used for solving of the second problem. The function $v(x,\tau)$ is represented as a series in eigenfunctions of this boundary value problem. The results can be used in the investigation process of heat transfer in a multilayer plate.

The paper deals with research of convergence for one of the generalizations of continued fractions -- branched continued fractions of the special form with two branches. Such branched continued fractions, similarly as the two-dimensional continued fractions and the branched continued fractions with two independent variables are connected with the problem of  the correspondence between a formal double power series and a sequence of the rational approximants of a function of two variables.

Unlike continued fractions, approximants of which are constructed unambiguously, there are many ways to construct approximants of branched continued fractions of the general and the special form. The paper examines the ordinary approximants and one of the structures of figured approximants of the studied branched continued fractions, which is connected with the problem of correspondence.

We consider some properties of approximants of such fractions, whose partial numerators are positive and alternating-sign  and partial denominators are equal to one. Some necessary and sufficient conditions for figured convergence are established. It is proved that under these conditions from the convergence of the sequence of figured approximants it follows the convergence of the sequence of ordinary approximants  to the same limit.
Advancement on the study of growth analysis of differential polynomial and differential monomial in the light of slowly increasing functions
Authors: Biswas T.
Published: August 2018

Study of the growth analysis of entire or meromorphic functions has generally been done through their Nevanlinna's characteristic function in comparison with those of exponential function. But if one is interested to compare the growth rates of any entire or meromorphic function with respect to another, the concepts of relative growth indicators will come. The field of study in this area may be more significant through the intensive applications of the theories of slowly increasing functions which actually means that $L(ar)\sim L(r)$ as $ r\rightarrow \infty $ for every positive constant $a$, i.e. $\underset{ r\rightarrow \infty }{\lim }\frac{L\left( ar\right) }{L\left( r\right) }=1$, where $L\equiv L\left( r\right) $ is a positive continuous function increasing slowly. Actually in the present paper, we establish some results depending on the comparative growth properties of composite entire and meromorphic functions using the idea of relative $_{p}L^{\ast }$-order, relative $_{p}L^{\ast }$- type, relative $_{p}L^{\ast }$-weak type and differential monomials, differential polynomials generated by one of the factors which extend some earlier results where $_{p}L^{\ast }$ is nothing but a weaker assumption of $L.$
A generalization of a localization property of Besov spaces
Authors: Ferahtia N. , Allaoui S.E.
Published: August 2018

The notion of a localization property of Besov spaces is introduced by G. Bourdaud, where he has provided that the Besov spaces $B^{s}_{p,q}(\mathbb{R}^{n})$, with $s\in\mathbb{R}$ and $p,q\in[1,+\infty]$ such that $p\neq q$, are not localizable in the $\ell^{p}$ norm. Further, he has provided that the Besov spaces $B^{s}_{p,q}$ are embedded into localized Besov spaces $(B^{s}_{p,q})_{\ell^{p}}$ (i.e., $B^{s}_{p,q}\hookrightarrow(B^{s}_{p,q})_{\ell^{p}},$ for $p\geq q$). Also, he has provided that the localized Besov spaces $(B^{s}_{p,q})_{\ell^{p}}$ are embedded into the Besov spaces $B^{s}_{p,q}$ (i.e., $(B^{s}_{p,q})_{\ell^{p}}\hookrightarrow B^{s}_{p,q},$ for $p\leq q$). In particular, $B_{p,p}^{s}$ is localizable in the $\ell^{p}$ norm, where $\ell^{p}$ is the space of sequences $(a_{k})_{k}$ such that $\|(a_{k})\|_{\ell^{p}}<\infty$. In this paper, we generalize the Bourdaud theorem of a localization property of Besov spaces $B^{s}_{p,q}(\mathbb{R}^{n})$ on the $\ell^{r}$ space, where $r\in[1,+\infty]$. More precisely, we show that any Besov space $B^{s}_{p,q}$ is embedded into the localized Besov space $(B^{s}_{p,q})_{\ell^{r}}$ (i.e., $B^{s}_{p,q}\hookrightarrow(B^{s}_{p,q})_{\ell^{r}},$ for $r\geq\max(p,q)$). Also we show that any localized Besov space $(B^{s}_{p,q})_{\ell^{r}}$ is embedded into the Besov space $B^{s}_{p,q}$ (i.e., $(B^{s}_{p,q})_{\ell^{r}}\hookrightarrow B^{s}_{p,q},$ for $r\leq\min(p,q)$). Finally, we show that the Lizorkin-Triebel spaces $F^{s}_{p,q}(\mathbb{R}^{n})$, where $s\in\mathbb{R}$ and $p\in[1,+\infty)$ and $q\in[1,+\infty]$ are localizable in the $\ell^{p}$ norm (i.e., $F^{s}_{p,q}=(F^{s}_{p,q})_{\ell^{p}}$).
Educación y derechos humanos a la luz de los estándares jurídicos de la diversidad sexual: Límites, resistencias y desafíos desde la experiencia socio-legislativa argentina
Authors: Arrubia Eduardo
Published: August 2018

En el mundo globalizado actual se profundiza el individualismo en el que los valores humanos están expuestos permanentemente a capitular dentro de las relaciones de mercado. En este contexto, la educación emerge como la herramienta idónea para revalorizar al sujeto como persona en sí misma y en su relación con las otras. En este sentido, el objetivo de este trabajo consiste en explorar los derechos humanos de las personas LGBTI y cómo estos derechos de la diversidad sexual operan como un enfoque analítico necesario para fomentar la tolerancia y el respeto por los otros seres a través de la educación. Para ello, se analiza la canalización del escenario internacional hacia el nivel local dentro de la República Argentina por medio de la Ley de Educación Sexual Integral Ley 26150 (2006) y se toman datos cualitativos y cuantitativos sobre la implementación de esta norma por medio de encuestas y entrevistas semiestructuradas a docentes. En este punto, se utilizan como criterios de análisis el grado de capacitación de docentes, la existencia de situaciones reales de discriminación por motivos sexuales en ámbitos educativos y la presencia de límites que provienen del entorno a la hora de aplicar estas políticas. De tal manera, se demuestra que a pesar de los avances legislativos progresistas, la aplicación cotidiana de la educación sexual presenta ciertas resistencias que provienen del entorno cultural como así también de la falta de capacitación del personal docente.
Creencias pedagógicas respecto de las dificultades específicas del aprendizaje de las matemáticas desde la perspectiva de las educadoras diferenciales en una escuela pública de Chile
Authors: Inostroza-Inostroza Fabián Andrés
Published: August 2018

La presente investigación tiene como objetivo describir las creencias pedagógicas de las personas educadoras diferenciales sobre las dificultades específicas del aprendizaje en matemáticas. Este estudio presenta un diseño cualitativo con enfoque etnográfico, en el que participaron cuatro docentes de educación especial y se emplearon como instrumentos de recolección de información la entrevista en profundidad y la observación participante. Como técnica de análisis del corpus discursivo obtenido, se utilizó el análisis cualitativo de contenido. Entre los hallazgos más relevantes se encuentran: las dificultades específicas del aprendizaje de las matemáticas corresponden a una condición intrinseca al estudiantado, que el origen de estas dificultades está asociada tanto a un problema de salud, como a metodologías inadecuadas de enseñanza de las matemáticas. Así mismo, se propone que estudiantes que poseen estas dificultades tienen un problema a nivel del razonamiento matemático, el que les impide progresar en el aprendizaje de esta asignatura escolar.
Enseñar como un “acto de amor” con métodos de enseñanza-aprendizaje no tradicionales en los entornos virtuales
Authors: Maldonado-Torres Sonia , Araujo Victoria , Rondon Oneirys
Published: August 2018

En el siguiente ensayo se aborda el concepto de “enseñar como un acto de amor” en los espacios virtuales. Trata sobre algunos métodos de enseñanza-aprendizaje no tradicionales y la incorporación de estos en los cursos virtuales que se ofrecen en las instituciones de educación superior. El objetivo es ayudar a los maestros y maestras a crear ambientes virtuales más efectivos utilizando métodos de enseñanza-aprendizaje no tradicionales que a su vez promuevan el enseñar como un “acto de amor”. Enseñar como “un acto de amor” implica que los maestros y las maestras incorporaran estos métodos de enseñanza-aprendizaje no tradicionales en los entornos virtuales, donde enfocan sus esfuerzos hacia el conocer su estudiantado y las necesidades de este mismo. Para entender estos métodos y su adaptación a los espacios virtuales se discutirán las teorías crítica y constructivista de la educación adaptándolas a los ambientes o entornos virtuales. Entre los métodos de enseñanza-aprendizaje no tradicionales que se mencionan en el ensayo están: el aprendizaje por asociación de experiencias, el aprendizaje por descubrimiento, el aprendizaje constructivista y el aprendizaje cooperativo entre otros.
Reflexiones en torno al fenómeno bullying en el contexto costarricense
Authors: Arias-Sandoval Leonel
Published: August 2018

Este ensayo tiene como objetivo reflexionar sobre el fenómeno social del bullying en el contexto costarricense, desde un enfoque holístico que considere las variadas causas que se relacionan con estos actos de violencia entre pares. El matonismo es una forma de violencia escolar, de ahí que resulte complejo dar una única explicación sobre sus causas, ya que pueden coexistir variados factores que pueden potenciarlo. Por tanto, se desprende que este es un fenómeno social complejo, multicausal y que se enmarca en una cultura escolar que se reproduce cotidianamente en las aulas o fuera de ellas. Además, tiene diferentes manifestaciones afectivas, cognitivas y socioculturales. El bullying es una construcción social multidimensional que se alimenta de la cultura del miedo, se manifiesta en abuso físico, psicológico, dominio o control y una expresión asimétrica de poder durante las interacciones sociales que se desarrollan dentro de los espacios educativos o fuera de ellos. En conclusión, todas las personas tenemos un grado de responsabilidad sobre esta problemática, el saber vivir y convivir libre de violencia, la práctica de una sana convivencia en el hogar, una educación basada en el respeto y, por último, la obligación de denunciar toda forma de maltrato o matonismo. Lo fundamental es construir ambientes respetuosos, solidarios e inclusivos desde un enfoque comunitario.
