Authors: C. J. Timna , D. Chandrika
Published: December 2017

Abstract:

Background: Hearing  plays  a  valid  role  in  speech  development  in  children. Otitis media with effusion is one among the commonest causes of hearing loss in children especially below 12 years. It is defined as the presence of fluid in the middle ear without signs or symptoms of acute ear infection

Methods: A prospective study was carried out in Lourdes Hospital, Kochi, over a period of 1 year from January 2013 to December 2013. Thirty patients with chronic middle ear effusion  below the age of 12 years were selected for the study.

Results: of the 30 patients  59.5% of patients were in the age group of 5-7 years of age, 16.6 % of patients were in the age group of 9-11 years of age .13.3%  of patients  each were in  the age group of 3-5 years and 7-9 years of age.Among  the 30 patients ,60% were male children and 40% patients were female children.Among the 30 patients , 40% of them had grade 3 adenoid hypertrophy ,33.3% of them had grade 2 adenoid  hypertrophy and  30% of them had grade 4 adenoid hypertrophy and none had grade 1 adenoids. majority of them had grade 3 adenoid hypertrophy by endoscopic assessment.Among  the 30 patients ,66.6 % of them had eustachian tube blockade by the adenoid mass and  33.4% of  them didn’t have eustachian tube blockade.  100% of them  with eustachian tube blockade found to have fluid on doing myringotomy  and  there was  20% of chance of absence of  fluid ,if there is absence of  eustachian tube blockade.

            Significant association was found between  type B tympanogram and presence of fluid on myringotomy .92.5% of patients with type B tympanogram had fluid on myringotomy . 57.1 % of patients with type C tympanogram  had fluid on doing myringotomy.There were 2 patients with grade 4 adenoid hypertrophy ,without eustachian tube blockade with  bilateral type C tympanogram and  there  was  bilateral dry tap on myringotomy. This reveals that type B tympanogram  and  eustachian tube blockade  better predictor of  otitis media with effusion   than grade of adenoid hypertrophy.

Conclusion:

    The present  study  showed that  chronic middle ear effusion was found to be most common  in the age group of  3-5  years of age group and  relatively common in the male children. Tympanogram type B was found to be  strongly associated with fluid on myringotomy .All the children with chronic middle ear effusion in the study group were found to have  ,grade 3 grade 2,and grade 4  adenoid hypertrophy in the  descending order of frequency.Grade 3 adenoid hypertrophy was present in majority of  the children in the study group .Lateral  adenoid hypertrophy ,abutting on the nasopharyngeal orifice of Eustachian tube was present in majority of children. Eustachian tube obstruction was found to be strongly  associated with  fluid on myringotomy and grommet insertion

Published: December 2017

Fungus is a rare cause of rhinosinusitis in children. Its incidence has been reported as ranging between 13.5 and 28%. Fungus balls are extramucosal tangled masses of fungal hyphae. It commonly involves just one paranasal sinus. Most commonly maxillary sinus is involved and occasionally sphenoid sinus. Concha bullosa is one of the most common anatomical variations in the nasal cavity, with a frequency of reporting ranging from 14-53.6%. There are very few case reports in which Concha bullosa was affected with fungus ball. In this case report 13 years female child presented with complaints of swelling right cheek. The patient underwent endoscopic sinus surgery and there was involvement of concha bullosa and sphenoid sinus with fungus ball. Fungus was confirmed on microscopic examination and culture. Fungus ball is a rare presentation of fungal rhinosinusitis. It should be considered in enlarged middle turbinate with heterogenous opacity on CT. The diagnosis should be confirmed by microscopy or culture.
Anthropological Aspects of the Relation Between Pastorinhas of Tapera and the «Street»
Authors: Jácome Graziela Armelao
Published: December 2017

the present work studies the ways how the residents of the rural community of Tapera, located in the county of Conceição do Mato Dentro/MG, and, at the same time involved or members of their most relevant cultural movement the Pastorinhas, identify the street. Based in the analysis about the «street» proposed by Henri Lefebvre, in The Urban Revolution, in which he presents arguments in behalf and against the street, the work identifies , within the Pastorinhas of Tapera, members defending booth points of view and highlights that, by rule, the opposition to the street is justified by the fact that is dangerous for children. However, instead of such divergence leading to «silence» defined by Lefebvre as a result of the repression imposed by those against the street, Better this way isn’t it? As in Tapera, the people stays in the street observes that the children, Pastorinhas and «street» can live in equilibrium.

Aspectos Antropológicos da Relação entre Pastorinhas da Tapera e a ‘Rua’

O presente trabalho estuda formas como moradores da comunidade rural denominada Tapera, localizada no Município de Conceição do Mato Dentro/MG, e, ao mesmo tempo envolvidos ou integrantes de seu movimento cultural mais importante, as Pastorinhas, identificam a ‘rua’. Com base na análise sobre ‘rua’ proposta por Henri Lefebvre, em A revolução urbana, na qual apresenta argumentos a favor da e contra a rua, o trabalho identifica, no seio das Pastorinhas da Tapera, integrantes defendendo um e outro ponto de vista e ressalta que, em regra, a oposição à ‘rua’ se justifica pelo fato de ela ser lugar de ameaça para crianças. No entanto, em vez de tal divergência conduzir ao “silêncio” definido por Lefebvre como resultado da repressão imposta por aqueles que são contra a rua, Melhor assim, né? Pois, na Tapera, o povo fica na rua observa que, à luz daqueles em nome dos quais se argumenta contra a ‘rua’, as crianças, Pastorinhas e ‘rua’ podem conviver equilibradamente.
The "Artifacts" of the ribeirinhos of Rio Mapuá, Marajó-PA, Brazil
Authors: Costa Eliane Miranda
Published: December 2017

it is proposed to discuss the relationship of the artifacts made by the riverside of the Mapuá river with the way of life of these peoples. Mapuá is one of the most extensive rivers in the municipality of Breves, archipelago of Marajó (PA). Along its length are its communities, formed by families, living in isolated houses and grouped in villages. Accompanying the dynamics of these communities, I mapped different artifacts produced by ribeirinhos with materials taken from the forest and used in various ways in everyday life. With a methodological combination involving the bibliographical survey and the field research, I show that the set of artifacts produced by the riverside mediate their relationship with the environment, with each other, with others and with materiality. They are artifacts that form their material and archaeological patrimony, a concept that contributes to demonstrate that the form of appropriation of this category can not do without the way of life of the traditional populations in the contemporary world.

Os “Artefatos” dos ribeirinhos do Rio Mapuá, Marajó-PA, Brasil

Propõe-se discutir a relação dos artefatos – objetos artesanais – confeccionados pelos ribeirinhos do rio Mapuá, com o modo de vida desses povos. O Mapuá é um dos rios mais extensos do município de Breves, arquipélago de Marajó, Estado do Pará. Ao longo de sua extensão encontram-se suas comunidades, formadas por famílias que moram em casas isoladas e agrupadas em vilas. Acompanhando a dinâmica dessas famílias, mapeei diferentes artefatos por elas construídos a partir de produtos retirados da floresta e utilizados de várias formas na vida cotidiana. São objetos que para elas formam seu patrimônio material e caracterizam-se como estratégias do saber-fazer e das relações estabelecidas com o meio ambiente amazônico. Neste texto trabalho com uma combinação metodológica que envolve a análise qualitativa do levantamento bibliográfico e da pesquisa de campo, com foco para a fotografia, observação e entrevistas com interlocutores envolvidos com a temática investigada.
La repercusión económico-contable de la baja del socio en la sociedad cooperativa: la incidencia de la NIC 32

Published: December 2017

En aras al principio de adhesión voluntaria y abierta, las cooperativas presentan singularidades en torno a la figura del capital social, que las diferencia de otras entidades mercantiles. Dichas peculiaridades comportan un tratamiento contable especial del capital cooperativo. Las normas internacionales de contabilidad prevén la calificación contable del capital cooperativo como pasivo financiero o como fondo propio, según la regulación legal y/o estatutaria del derecho de baja del socio. Este planteamiento se ha traspuesto al derecho contable de la Unión Europea y de España, afectando a un buen número de cooperativas europeas, incidiendo en su imagen financiera. En este trabajo tratamos las peculiaridades contables que emanan de la posibilidad de la baja del socio en el marco de la normativa contable internacional, nacional y los últimos posicionamientos de organismos reguladores.Recibido: 12 junio 2017Aceptado: 14 octubre 2017Publicación en línea: 22 diciembre 2017

Authors: Marmarà Danika , Marmarà Vincent , Hubbard Gill
Published: December 2017

Background and Purpose: Translating, adapting, and piloting Champion’s Health Belief Model Scale for Mammography Screening (CHBMS-MS) and Revised Illness Perception Questionnaire (IPQ-R) among Maltese women. Methods: The Maltese questionnaire (Maltese Breast Screening Questionnaire [MBSQ]) was developed through 9 steps. Bilingual women (n = 15) completed MBSQ at 2 time points. Results: During forward-backward translations (Steps 1–4), 4 English controversial terms were raised. Twelve experts agreed on terminologies during adaptation process (Step 5). Following face validity (n = 6; Step 6), 3 items were deleted. Following reconciliation (Step 7) and proofreading (Step 8), MBSQ consisted of 121 items. Pilot testing (Step 9) showed positive correlation (CHBMS-MS = .87, IPQ-R = .85; p < .001); high Cronbach’s alpha (CHBMS-MS = .93, IPQ-R = .92); overall acceptable internal consistency (CHBMS-MS = .69–.83, IPQ-R = .75–.93); and acceptable test–retest reliability correlations: CHBMS-MS (Maltese = .62–.76; English = .61–.84), IPQ-R (Maltese = .63–.82; English = .61–.91; p < .001). Conclusions: Maltese and English scale items demonstrated high reliability and validity preliminary values.
MOLECULAR IDENTIFICATION OF SARCOPTES SCABIEI VAR. CUNICULI FROM SURABAYA AND MALANG REGIONS OF EAST JAVA

Published: December 2017

Scabies is a zoonotic skin disease caused by Sarcoptes scabiei mites. As an emerging/re-emerging parasitic disease, scabies represents a significant global threat to both human and animal health. Numerous cases of scabies in Indonesia have been reported, which support research on the prevalence of S. scabiei. However, most such studies have involved conventional morphological studies, with limited molecular diagnostic studies. The purpose of the present study was the genetic characterization of S. scabiei var. cuniculi in domestic rabbits to generate baseline genotypic data. S. scabiei var. cuniculi was isolated and identified from scabies-infected rabbits from the Surabaya and Malang regions of East Java. Molecular identification was performed using Polymerase Chain Reaction (PCR) using specific primers targeting the COX1 gene. We performed COX1 PCR using rabbit isolates of S. scabiei from Indonesia. To the best of our knowledge, no such study had been reported previously. This study was performed in the Laboratory of Veterinary Parasitology, Faculty of Veterinary Medicine and the Tropical Disease Diagnostic Center Laboratory, Universitas Airlangga. The results with agarose gel electrophoresis revealed a 289 bp PCR product amplified from the DNA of S. scabiei isolates from both Surabaya and Malang in accordance with the expected COX1 amplicon size, that indicated a single band 289 bp in length, demonstrating specific detection of S. scabiei var. cuniculi from Surabaya and Malang using COX1 primers. The results were consistent with the calculated amplicon size based on primer positions within the COX1 locus, with the forward primer spanning nucleotides 61–94, and the reverse primer spanning nucleotides 331–350 ( 350 − 61 = 289 bp).  PCR genotyping of the isolates yielded an identical nucleotide length of 289 bp. Further studies are required to sequence the amplified fragments for homology assessment.

Authors: Lu Hongfang , Huang Kun , Fu Lingdi , Zhang Zhihao , Wu Shijuan , Lyu You
Published: December 2017

Due to poor ventilation conditions in the tunnel, if gas pipeline leaks, the consequence of the accident will be more serious. Therefore, before the emergency repair, gas in the tunnel needs to be excharged so as not to explode during the repair process. Therefore, it is necessary to study the ventilation of gas in the tunnel. Based on the computational fluid dynamics (CFD) theory and taking the Yanyingshan tunnel section of China-Myanmar pipeline as an example, this paper uses Fluent software to establish the leakage model of the gas pipeline and fan model in the tunnel and analyzes the influence of different fan locations and number of fans on gas concentration. It can be concluded that: (1) the use of press-in method makes it more efficient to discharge gas out of the tunnel. (2) In order to make ventilation efficient, the fan should be arranged in a higher position and needs to be at a distance from the top of the tunnel. (3) Parallel use of two fans has better ventilation effect than single fan.

A busca por desenvolvimento econômico e energético levou o governo federal brasileiro, em pleno período de ditadura militar, a avançar para o norte do país, onde se constatou um relevante potencial hidroelétrico presente na região. A UHE de Balbina-AM representa uma das várias intervenções políticas organizadas e implementadas como promessas de progresso para a Amazônia. Tal construção foi concebida sob diversas problemáticas, muitas das quais questionáveis até os dias de hoje, isso porque ocorreram modificações sociais, ambientais e econômicas no entorno do reservatório construído. Nesta pesquisa realizou-se um estudo onde foi possível demonstrar e analisar as transformações ocorridas no entorno do Reservatório da Usina Hidrelétrica de Balbina, tendo por finalidade entender como se organiza o atual espaço geográfico. Para a pesquisa foi utilizado o método geossistêmico usando como metodologia: as coletas de campo, imagens de satélite para elaboração de mapas, pesquisa bibliográfica e documental, além de visitas aos institutos que colaboraram com informações complementares. Através da pesquisa foi possível identificar as modificações na paisagem e o processo de desterritorialização dos Waimiri- atroaris ocasionados pela implementação do projeto da UHE de Balbina, além é claro no que diz respeito às novas formas de uso e ocupação do solo. Os resultados também demonstram que mesmo com os grandes impactos ocorridos pela construção e implantação da usina, a água do reservatório contribuiu para a formação de novas territorialidades ocasionando as transformações socioespaciais em seu entorno.

Augmentation of Well Productivity Using Slant and Horizontal Wells
Authors: Joshi S. D.
Published: December 2017

This paper presents an equation to calculate the productivity of horizontal wells and a derivation of that equation using potential fluid flow theory. This equation may also be used to account for reservoir anisotropy and well eccentricity (i.e., horizontal well location other than mid-height of a reservoir). The theoretical predictions were used to calculate the effective well bore radius and the effective skin factors of horizontal wells. Laboratory experiments using an electrical analog were also conducted. The present laboratory experimental data and also the laboratory data available in the literature show good agreement with the theoretical equation, indicating its accuracy.

The paper also compares vertical, slant, and horizontal well productivity indices, assuming an equal drainage area. In addition, the comparison also assumes an equal reservoir contact area for slant and horizontal wells. The results show that in a 100 ft (30.48 m) thick reservoir, horizontal well productivities are 2 to 5 times greater than unstimulated vertical or slant well productivities, depending upon reservoir anisotropy. Conversely, in a 400 ft (122 m) thick reservoir, slant wells perform better than horizontal wells if vertical permeability is less than the horizontal permeability.

Horizontal wells perform significantly better than vertical wells in reservoirs with gas cap and/or bottom water. This study reports an equation to compare horizontal and vertical well gas coning tendencies.

The results indicate that horizontal wells are suitable for reservoirs which are thin, show high vertical permeability or exhibit gas and water coning problems. The equations reported in this paper should be useful in an initial evaluation of a horizontal well drilling proposal.
Efficiency Improvement of a Rotary Gas Separator by Parametric Study and Gas/Liquid-Flow Analysis
Authors: Derakhshan Shahram , Riahi Fazel , Bashiri Mohamad
Published: December 2017

In this study, a gas/liquid flow has been numerically investigated in a rotary gas separator (RGS) to improve the performance of the RGS. One-phase flow and then two-phase flow were analyzed in an inducer, which is the main component of the RGS. A parametric study showed that reduced blade thickness and a higher number of blades increased the inducer's head. However, an inducer with two blades generated greater head. Higher inlet-flow temperature (by inlet preheating) improved operation conditions, especially in lower flows. In addition, smaller bubble sizes led to a lower head. Alternately, the changes are not significant, and results are close and similar in smaller sizes. In the next step, the performance of the designed RGS was analyzed by computational fluid dynamics (CFD) and validated with available experimental data. Then, the effect of the quantity of the gas-output ports on the RGS's efficiency was studied. As a result, the system with four ports was suggested as optimal. Moreover, results showed that increasing the length of the separator zone leads to increasing the efficiency until reaching an optimal length equal to the length of the inducer zone. Finally, the effect of the blade number was studied for various rated points.
Were valuable art works an economic form of money during the German Third Reich Period and its aftermath?
Authors: Gentle Paul , Giliberti Marco
Published: December 2017

This examines the special use of art works as a store of value in Germany during the Third Reich era. Some Jews were able to buy their freedom, as the fascists closed in. Then as the Third Reich fell, some escaping fascists used art works to secure freedom outside of Germany. One of the characteristics of money is a store of value. When confidence in a currency is present, the more conventional form of money takes precedence. A respected, economic form of currency and coin has all three elements of money: medium of exchange, store of value and unit of account. This last trait is especially absent when using various art works as money, as there is no agreed upon unit of account with such different art. Furthermore, art works could not qualify as a medium of exchange, since only a very small amount of the population was involved in this way of dealing in art during the stressed times for the Third Reich.
Evolution of Host Target Cell Specificity During HIV-1 Infection
Authors: Council Olivia D. , Joseph Sarah B.
Published: December 2017

Background: Many details of HIV-1 molecular virology have been translated into lifesaving antiviral drugs. Yet, we have an incomplete understanding of the cells in which HIV-1 replicates in untreated individuals and persists in during antiretroviral therapy.

Methods: In this review we discuss how viral entry phenotypes have been characterized and the insights they have revealed about the target cells supporting HIV-1 replication. In addition, we will examine whether some HIV-1 variants have the ability to enter cells lacking CD4 (such as astrocytes) and the role that trans-infection plays in HIV-1 replication.

Results: HIV-1 entry into a target cell is determined by whether the viral receptor (CD4) and the coreceptor (CCR5 or CXCR4) are expressed on that cell. Sustained HIV-1 replication in a cell type can produce viral lineages that are tuned to the CD4 density and coreceptor expressed on those cells; a fact that allows us to use Env protein entry phenotypes to infer information about the cells in which a viral lineage has been replicating and adapting.

Conclusion: We now recognize that HIV-1 variants can be divided into three classes representing the primary target cells of HIV-1; R5 T cell-tropic variants that are adapted to entering memory CD4+ T cells, X4 T cell-tropic variants that are adapted to entering naïve CD4+ T cells and Mtropic variants that are adapted to entering macrophages and possibly other cells that express low levels of CD4. While much progress has been made, the relative contribution that infection of different cell subsets makes to viral pathogenesis and persistence is still being unraveled.
Evaluation of the Coping Through Football Project: Physical Activity and Psychosocial Outcomes
Authors: Friedrich Bettina , Mason Oliver John
Published: December 2017

Background:

Football is increasingly used as an adjunct intervention for people with mental problems, intended to improve their mental, physical and social health.

Objective:

The aim of this study is to evaluate psychosocial outcomes and physical activity in participants of “Coping Through Football” (CTF), a London-based football intervention for people who receive secondary mental health care.

Methods:

In a one group pre-post study design, participants completed self-report measures on physical activity and mental well-being at baseline (i.e. when joining the intervention), and at 6 months and 12 months thereafter. Perceived quality of life was measured using the WHOQOL-BREF which assess domains such as physical health, psychological well-being, social relationships and environment. The Rosenberg Self-esteem scale was used to measure self-esteem in the participants. Self-reported physical activity (vigorous activity, moderate activity, walking and sitting) was assessed using the short form of the International Physical Activity questionnaire (IPAQ).

Results:

For the 6 months follow up, data was available for 72 participants; at 12 month follow up data was available for 32 participants. Levels of vigorous activity doubled between baseline (102.98 min/week) and the short term follow up (196.85 min/week) as well as between baseline (117.26 min/week) and the one year follow up (248.23 min/week). For moderate activity, we find similar results with an improvement from 78.13 min/week at baseline to 149 min/week at the short term follow up and an increase from 87.74 min/week at baseline to 209.61 min/week. Increases on psychosocial measures were more modest, reaching significance at only the 6 month time point. There were no statistically significant changes with regard to the time spent sitting or walking at either the 6 or the 12 month follow up.

Conclusion:

While the impact on psychosocial measures was only moderate, the increase in physical activity in participants encourages the use of adjunct football interventions for people with mental health problems as a means to increase physical activity levels.

Published: December 2017

This study aimed to investigate the effects of ferrihydrite (Fh) nanoparticle loading on the physicochemical properties of polysulfone (PSf) membranes fabricated via the phase inversion method. The morphologies and physicochemical properties of prepared Fh and PSf/Fh mixed matrix membranes (MMMs) were characterized using transmission electron microscopy (TEM), X‐ray diffraction analysis (XRD), Fourier transmission infra‐red (FTIR), scanning electron microscopy (SEM), atomic force microscopy (AFM), pure water flux analysis, contact angle measurement, and membrane porosity analysis. FTIR study indicated that a new O‐H band was formed when Fh was added into the membrane matrix. SEM analysis showed the formation of typical asymmetric membrane structures with elongated fingerlike and looser porous layers. Increasing the loading of Fh significantly enhanced membrane pure water flux from 230.2 L/m2•h (M‐Fh 0%) to 726.6 L/m2•h (M‐Fh 15.3%), attributed to the improved membranes structures, membranes wettability, surface roughness, and overall porosity. The findings suggest incorporation of Fh into PSf membranes improves physicochemical properties of the membranes which are applicable for water/wastewater treatment.

Authors: Manyatshe Alusani , Fosso‐Kankeu Elvis , van der Berg Divan , Lemmer Nico , Waanders Frans , Tutu Hlanganani
Published: December 2017

About 44 surface water samples were collected in the wet and dry seasons around mining areas near the city of Potchefstroom in South Africa, and physicochemical parameters were analyzed to assess the speciation of pollutants and impact on dispersion potential. It was found that concentrations of the trace elements measured decreased significantly during the dry season. High concentrations of trace elements during the wet season were correlated to high effluents from anthropogenic sources which were flowing into the surface water. Aqueous metal speciation in both seasons was conducted using the PHREEQC geochemical modelling code. The seasonal variation of species observed was due to changes in the physicochemical quality of water between the two seasons. Collected data indicated that high percentages of Ca and Mg were present as free hydrate species, whereas the Fe, Cd, As, and U were mostly present as carbonate or hydroxide species.
A Novel Approach for Fully Automated, Personalized Health Coaching for Adults with Prediabetes: Pilot Clinical Trial (Preprint)
Authors: Everett Estelle , Kane Brian , Yoo Ashley , Dobs Adrian , Mathioudakis Nestoras
Published: December 2017

BACKGROUND

Prediabetes is a high-risk state for the future development of type 2 diabetes, which may be prevented through physical activity (PA), adherence to a healthy diet, and weight loss. Mobile health (mHealth) technology is a practical and cost-effective method of delivering diabetes prevention programs in a real-world setting. Sweetch (Sweetch Health, Ltd) is a fully automated, personalized mHealth platform designed to promote adherence to PA and weight reduction in people with prediabetes. 

OBJECTIVE

The objective of this pilot study was to calibrate the Sweetch app and determine the feasibility, acceptability, safety, and effectiveness of the Sweetch app in combination with a digital body weight scale (DBWS) in adults with prediabetes.

METHODS

This was a 3-month prospective, single-arm, observational study of adults with a diagnosis of prediabetes and body mass index (BMI) between 24 kg/m2 and 40 kg/m2. Feasibility was assessed by study retention. Acceptability of the mobile platform and DBWS were evaluated using validated questionnaires. Effectiveness measures included change in PA, weight, BMI, glycated hemoglobin (HbA1c), and fasting blood glucose from baseline to 3-month visit. The significance of changes in outcome measures was evaluated using paired t test or Wilcoxon matched pairs test.

RESULTS

The study retention rate was 47 out of 55 (86%) participants. There was a high degree of acceptability of the Sweetch app, with a median (interquartile range [IQR]) score of 78% (73%-80%) out of 100% on the validated System Usability Scale. Satisfaction regarding the DBWS was also high, with median (IQR) score of 93% (83%-100%). PA increased by 2.8 metabolic equivalent of task (MET)–hours per week (SD 6.8; P=.02), with mean weight loss of 1.6 kg (SD 2.5; P<.001) from baseline. The median change in A1c was −0.1% (IQR −0.2% to 0.1%; P=.04), with no significant change in fasting blood glucose (−1 mg/dL; P=.59). There were no adverse events reported.

CONCLUSIONS

The Sweetch mobile intervention program is a safe and effective method of increasing PA and reducing weight and HbA1c in adults with prediabetes. If sustained over a longer period, this intervention would be expected to reduce diabetes risk in this population.

Justiciability, Access to Justice and the Development of Constitutional Law in Canada
Authors: Kennedy Gerard J , Sossin Lorne
Published: December 2017

Concentrating on Canadian experience, specifically litigation under the Canadian Charter of Rights and Freedoms (the ‘Charter’), this article seeks to reconcile the access to justice benefits of summary procedures with the government litigant's duty to act in the public interest (or as a ‘model litigant’) and uphold the rule of law. Though acknowledging the benefits that can result from the use of summary procedures to end litigation, the authors observe that compliance with strict requirements in procedural law are frequently dispensed with in the Charter context. In fact, summary procedures can have a devastating effect on the development of Charter rights. The authors ultimately posit that the government should have a duty of restraint in using summary procedures to end public law litigation, and courts should be reluctant to permit the government to preclude such litigation aimed at advancing the evolution of the Charter from reaching hearings on the merits.
The Unfolding Purpose of Fairness
Authors: Groves Matthew
Published: December 2017

The duty to observe the requirements of procedural fairness is well settled in Australian administrative law. So too is the variable content of that duty and the possibility that it may be limited or excluded by legislation expressed in suitably clear terms. One key aspect of fairness that is not yet clear is its purpose. Why do courts require those who exercise public or official power to act fairly? The question cannot be fully answered by reliance on legislative intent or reference to the common law because recourse to one or both of these possible sources of the duty to act fairly does not necessarily answer why that duty is drawn from the common law or implied as part of statutory interpretation. This article examines recent steps by courts and commentators that suggest an exploration of the purpose of fairness may be beginning to occur.

Nesta comunicação apresentamos uma pesquisa desenvolvida com uma turma do ensino médio integrado de uma escola da rede federal de ensino da cidade de Manaus. O obetivo da pesquisa foi de avaliar qual o papal exercido pelos conhecimentos prévios para elaboração de hipóteses em questõs abertas no ensino de física. Constatamos que o conhecimento prévio é uma condição necessária mas não suficiente, pois possibilitou ao alunado formularem as hipóteses embora, em sua maioria, elas não estivessem adequadas ao que é posto pela física. Isto indica que o senso comum foi o conhecimento mais utilizado para formulá-las ao invés do conhecimento científico, como esperado.

UNDERSTANDING INVESTORS’ BEHAVIOR DURING STOCK PRICE MANIPULATION: A CASE OF INDONESIA’S STOCK MARKET
Authors: Akbar Riznaldi
Published: December 2017

Penelitian ini mencoba untuk mencari pola tekstual yang berkaitan dengan perilaku investor dan sentimen selama manipulasi harga saham di Bursa Efek Indonesia. Kami mengusulkan analisis text mining untuk menunjukkan proses penggalian informasi dari berita dan media rilis Tweeter selama periode 2000 sampai 2014. Kami mengambil tiga sampel perusahaan dari PT AGIS Tbk (TMPI), PT Garda Tujuh Buana Tbk (GTBO) dan PT Bumi Resources Tbk (BUMI) yang telah ditunjukkan mengalami manipulasi harga saham. Perusahaan-perusahaan ini mengalami harga saham apresiasi abnormal dan diikuti dengan penurunan tajam dari sekitar 90 persen dalam waktu singkat. Informasi yang diekstrak dari Tweeter dan analisis sentimen memberikan bukti bahwa berita dan media rilis cenderung menghasilkan umum istilah kunci negatif seperti "terjun", "drop", dan "jatuh"; serta istilah yang terkait dengan laporan laba rugi seperti "kehilangan", "keuntungan", "bersih", "penjualan" dan "pendapatan" .Ini menunjukkan bahwa sebagian besar investor akan memiliki bias negatif dan menderita lebih ketika harga saham mengalami signifikan menurun. Hal ini juga mengungkapkan bahwa investor lebih cupet pada laporan laba rugi daripada menganalisis gambaran besar dari penilaian dasar perusahaan secara keseluruhan. Dengan demikian kita berpendapat bahwa basis pengetahuan ini dan istilah kunci dapat digunakan untuk mencerminkan karakteristik umum dari perilaku investor selama manipulasi harga saham di pasar saham Indonesia.This study attempts to search textual patterns that are associated with investor behavior and sentiment during stock price manipulation in Indonesia’s Stock Market. We propose text mining analysis to demonstrate the process of extracting information from news and media release of Tweeter over the period of 2000 to 2014. We took three sample firms of PT AGIS Tbk (TMPI), PT Garda Tujuh Buana Tbk (GTBO) and PT Bumi Resources Tbk (BUMI) that have been indicated experiencing stock price manipulation. These firms experienced an abnormal stock price appreciation and followed with a sharp decline of about 90 per cent within short period of time. The extracted information from Tweeter and sentiment analysis provide evidence that news and media releases tend to yield common negative key terms such as “plunge”, “drop”, and “fall”; as well as terms related to income statements such as “loss”, “profit”, “net”, “sales” and “revenue”.It shows us that most investors would have negative bias and suffer more when the stock price experienced a significant decline. It also reveals that investors are more short-sighted on the profit and loss statements rather than analyzing the big picture of corporate fundamental valuation as a whole. We thus argue that these knowledge bases and key terms could be used to reflect common characteristics of investor behavior during stock price manipulation in the Indonesia’s stock market.
