A quick method to compute sparse graphs for traveling salesman problem using random frequency quadrilaterals
Authors: Wang Yong
Published: February 2019

Traveling salesman problem (TSP) is extensively studied in combinatorial
optimization and computer science. This paper gives a quick method to
compute the sparse graphs for TSP based on the random frequency
quadrilaterals so as to reduce the TSP on the complete graph to the TSP on
the sparse graphs. When we choose N frequency quadrilaterals containing an
edge e to compute its total frequency, the frequency of e in the optimal
Hamiltonian cycle will be bigger than that of most of the other edges. We
fix N to compute the frequency of each edge and the computation time of the
quick method is O(n2). We suggest two frequency thresholds to trim the edges
with the frequency below the two frequency thresholds and generate the
sparse graphs for TSP. The experimental results show we compute the sparse
graphs for these TSP instances in the TSPLIB.
A fast learn++.NSE classification algorithm based on weighted moving average
Authors: Shen Yan , Zhu Yuquan , Du Jianguo , Chen Yong
Published: February 2019

Current researches of incremental classification learning algorithms mainly
focus on learning from data in a stationary environment. The incremental
learning in a non-stationary environment (NSE), where the underlying data
probability distribution changes over time, however, has received much less
attentions despite the abundant real applications have generated the
long-term and cumulative big data in NSE. Thus, the incremental learning in
NSE has gradually received extensive attentions. Nevertheless, the popular
incremental classification learning algorithms currently for NSE such as SEA
and DWM generally place strict restrictions on the changes. These algorithms
can only deal with gradual drift and noncyclical and no new category
situations. Therefore, it is highly necessary to develop a novel efficient
incremental classification learning algorithm for the gradually cumulative
big data in complex NSE. The recently proposed Learn++.NSE algorithm is an
important research achievement in this field. However, the vote weight of
each base-classifier of the Learn++.NSE depends on its whole error rates in
the environments experienced. Therefore, the classification learning
efficiency of the Learn++.NSE should be further improved. A novel fast
Learn++.NSE algorithm based on weighted moving average (WMA-Learn++.NSE) is
presented in this paper, which computes the weighted average of error rates
using the sliding window technology to optimize the weight calculation. By
only using the recent classification error rates of each base-classifier
inside the sliding window to calculate the vote weight, the WMA-Learn++.NSE
accelerates the compute of vote weight and improves the efficiency of
classification learning. The verification experiments and performance
analyses on both synthetic and real data set are presented in this paper.
The experimental results show that the WMA-Learn++.NSE can achieve a higher
execution efficiency compared to the Learn++.NSE in getting the equivalent
classification correct rate.

Authors: Wang Zhanzhong , Zhao Liying , Cao Ningbo , Chen Mingtao
Published: February 2019

With the growing presence of hazardous materials in daily life, a large
number of institutions and scholars have been paying close attention to this
field, providing new directions for exploring hazardous materials
distribution patterns. This paper employs two fuzzy random variables,
transportation cost and risk, to put forward a bi-level minimum objective
programming model with a chance measure constraint within a specified chance
level. The lower level is to seek minimum transportation costs and the upper
level is for minimum risk. The model presented in this article
simultaneously designs the hybrid algorithm, which is the combination of the
fuzzy random simulation with the genetic algorithm. In the end, a smallscale
instance is given to account for the efficiency of the presented model and
algorithm, and the best distribution solution is presented.

Authors: Zhong Yihua , Lv Xiaodie , Bao Min , Li Lina , Yang Yan
Published: February 2019

In order to realize Digital Oil Field, some key problems need to be improved,
esp. accurate and automatic prediction of oilfield development indexes which
may be resolved by designing of intelligent prediction system. With the
shortcoming of inference of system designed by us, automatic inference
problem for a complicated intelligent prediction system was improved using
pattern recognition method. First, intelligent prediction system and the
methods as well as principles of pattern recognition were introduced. Then
the framework of intelligent prediction system based on pattern recognition
was formulated by using technologies and methods of human-computer
interface, fuzzy processing and pattern recognition. Secondly, the knowledge
base was extended as augmented knowledge base with introducing credibility
to measure uncertainty of knowledge. Particularly, the methods and
principles of pattern recognition were used to design two recognizers and
one inferring machine. Moreover, the method of selecting predictive model
based on reasoning of pattern recognition was presented by coupling them and
intelligent prediction system. Finally, the design of improving intelligent
prediction system of oilfield development indexes was simulated. Simulation
result shows that improved system may automatically realize to select
optimal prediction model by computer according to different reservoirs and
different development stages. The results obtained in this thesis will
helpful to design for intelligent prediction system.
Mining negative sequential patterns from frequent and infrequent sequences based on multiple level minimum supports
Authors: Qiu Ping , Jiang Xiaoqi , Hao Feng , Xu Tiantian , Dong Xiangjun
Published: February 2019

Negative sequential patterns (NSP) are critical and sometimes much more
informative than positive sequential patterns (PSP) in many intelligent
systems and applications. However, the existing NSP algorithms do not allow
negative items being contained in an element except the NegI-NSP algorithm,
which can obtain many meaningful sequences with negative items in an
element. NegI-NSP, however, hasn?t considered the following problems: (1) it
uses a single minimum support to all size sequences, which is unfair to a
long size sequence; (2) it only mines NSP from PSP, not from infrequent
positive sequences (IPS), which also contain many useful NSP. So we propose
an efficient algorithm, named MLMS-NSP, to mine NSP based on multiple level
minimum supports (MLMS) from PSP and IPS. Firstly, MLMS scheme is proposed
by assigning different minimum supports to sequences with different sizes.
Secondly, IPS are constrained by combining MLMS, and then the NSP is
obtained from these IPS. Finally, experimental results show that the
MLMS-NSP algorithm can effectively mine NSP from IPS, and the time efficiency
is higher than using single minimum support.
A new evaluation model for uncertain traffic pollution control planning under the risk attitudes of the decision maker
Authors: Wei Ming , Li Yun , Sun Bo , Wang Jianning
Published: February 2019

The purpose of this work is to address a new multi-attribute decision making
evaluation model for uncertain traffic pollution control program, by
considering the preference of each decision maker to different programs. An
interval mapping function was introduced to specify the risk attitudes of
the decision maker, which can dissect the original problem to decision
problems of traditional values. The proposed model can quantitatively
analyze how the risk attitudes of the decision makers affect efficiency ranking
for different plans. Case studies performed on the four plans showed that the
optimistic ranking of the four plans is the same as that of the neutral
situation, but there is a significant difference with the results of
pessimistic situation.

The primary goal of this paper is to develop fuzzy stabilizer theory in
BL-algebras. Two types of fuzzy stabilizers are introduced and their related
properties are given. Also, the relationships between fuzzy stabilizers and
several fuzzy filters are discussed. Finally, by means of fuzzy stabilizers,
it is proven that the collection of all fuzzy filters in BL-algebras forms a
residuated lattice. These results will provide a solid algebraic foundation
for the consequence connectives in fuzzy logic.
Local view based cost-sensitive attribute reduction
Authors: Li Jingzheng , Chen Xiangjian , Wang Pingxin , Yang Xibei
Published: February 2019

In traditional cost-sensitive attribute reduction, the variation of decision
cost is referred to as a global difference of costs because the considered
decision cost is the variation of sum of decision costs over all objects.
However, such reduction does not take the variation of decision costs of
each object into account. To solve this problem, a local view based
cost-sensitive attribute reduction is introduced. Firstly, through
considering the variation of decision costs of single object if the used
attributes change, a local difference of costs is presented. Secondly, on the
basis of the fuzzy decision-theoretic rough set model, a new significance
function is given to measure the importance of attribute. Finally, the
experimental results illustrate that by comparing the traditional reduction,
the proposed local view can decreases both global and local differences of
costs effectively on several UCI data sets.
Topology and semantic based topic dependency structure discovery
Authors: Zhao Anping , Manandhar Suresh , Yu Lei
Published: February 2019

As an important enabler in achieving the maximum potential of text data
analysis, topic relationship dependency structure discovery is employed to
effectively support the advanced text data analysis intelligent application.
The proposed framework combines an analysis approach of complex network and
the Latent Dirichlet Allocation (LDA) model for topic relationship network
discovery. The approach is to identify topics of the text data based on the
LDA and to discover the graphical semantic structure of the intrinsic
association dependency between topics. This not only exploits the
association dependency between topics but also leverages a series of
upper-level semantic topics covered by the text data. The results of
evaluation and experimental analysis show that the proposed method is
effective and feasible. The results of the proposed work imply that the
topics and relationships between them can be detected by this approach. It
also provides complete semantic interpretation.
RDF keyword search using multiple indexes
Authors: Lin Xiaoqing , Zhang Fu , Wang Danling , Cheng Jingwei
Published: February 2019

Since SPARQL has been the standard language for querying RDF data, keyword
search based on keywords-to-SPARQL translation attracts more intention.
However, existing keyword search based on keywords-to-SPARQL translation
have limitations that the schema used for keyword-to-SPARQL translation is
incomplete so that wrong or incomplete answers are returned and advantages
of indexes are not fully taken. To address the issues, an inter-entity
relationship summary (ER-summary) is constructed by distilling all the
inter-entity relationships of RDF data graph. On ER-summary, we draw circles
around each vertex with a given radius r and in the circles we build the
shortest property path index (SP-index), the shortest distance index
(SD-index) and the r-neighborhoods index by using dynamic programming
algorithm. Rather than searching for top-k subgraphs connecting all the
keywords centered directly as most existing methods do, we use these indexes
to translate keyword queries into SPARQL queries to realize exchanging space
for time. Extensive experiments show that our approach is efficient and
effective.
Calibrating linear continuous-time dynamical systems via perturbation analysis
Authors: Weng Peter , Phoa Frederick
Published: February 2019

This work considered the continuous-time linear dynamical systems described
by the matrix differential equations, and aimed at studying the perturbation
analysis via solving perturbed linear dynamical systems. In specific, we
solved Riccati differential equations and continuous-time algebraic Riccati
equations with finite and infinite times respectively. Moreover, we stated
some assumptions on the existence and uniqueness of the solutions of the
perturbed Riccati equations. Similar techniques were applied to the
discrete-time linear dynamical systems. Two numerical examples illustrated
the efficiency and accuracy.
OLAP on multidimensional text databases: Topic network cube and its applications
Authors: Zhang Zhiyuan , Wang Hong , Feng Xingjie
Published: February 2019

Multidimensional text data contains both structured attributes and
unstructured text. Unlike the traditional numerical data, it is not
straightforward to apply online analytical processing on multidimensional
text data. Although some OLAP methods such as topic cube have been proposed
in order to effectively utilize its structured information and valuable text
data, these methods cant tell the relations of topicwords. Considering that
topics usually consist of several subtopics and each subtopic usually
contains some topic words, we here use a topic network manner, in which
related topic words are connected, to express the complex relations of
topics. This paper introduces a new concept of topic network cube to perform
OLAP analysis on multidimensional text databases. Firstly, we propose a
method called GL-LDA based on Gibbs sampling outputs of Labeled LDA to
measure the relations between topic words. Secondly, we give a storagemodel
of topic network cubewhich can efficiently generate topic network using
GL-LDA. Thirdly, we show how to perform OLAP analysis on topic network cube.
Experimental results show that we can analyze multidimensional text
databases in different granularity easily and effectively using just a few
simple SQL statements, and the output network provides rich and useful
information of topics.
New trends in the international political dynamics of natural gas trade
Authors: Stanojevic Petar , Misev Gordana
Published: February 2019

The paper analyses the global natural gas market in the context of the
identification of influential international factors or phenomena that will
determine trends in the next foreseeable period. Natural gas is an energy
source that, in addition to renewable energy sources, shows a high and
continuous growth trend. Almost all countries possess certain means to
produce electricity (including renewable energy sources) or obtain it from
the immediate environment, while gas and oil are energy products that all
countries use but do not have. Trends related to these two energy sources
and the factors that influence the creation of their market are numerous and
complex. The authors present some important aspects and approaches to energy
security issues related to global energy challenges, as well as the risks
and threats that the world is exposed to today and in the future. The
authors conclude that natural gas as the energy of the future is recording
increasing consumption, which requires a profound analysis of trends in this
area.
Parliamentary assembly as a model for the revitalisation of the united nations general assembly
Authors: Gordanic Jelica
Published: February 2019

The paper analyses the revitalization of the General Assembly of the United
Nations in the context of the establishment of the Parliamentary Assembly, a
potentially new organ within the UN system. The United Nations system deals
with the lack of democratic capacity. Establishment of the Parliamentary
Assembly which consisted of the citizens of UN members could eliminate the
lack of democratic capacity and improve the entire UN structure. The author
analyzes the possibilities of establishment of the Parliamentary Assembly,
its potential jurisdiction and examines its potential contribution to the
revitalization of the General Assembly. The paper points out that the
establishment of the Parliamentary Assembly can contribute to the
actualization of the agenda, improve the quality of resolutions and reduce
the number of repetitive resolutions of the General Assembly. Moreover, it
could achieve an indirect impact on democratization and transparency of the
work of the Security Council. The author considers funding and the
composition of the Parliamentary Assembly as possible threats for the
establishment of this organ. These facts also represent the threats for the
process of revitalization of the General Assembly. The author concludes the
potential establishment of the Parliamentary Assembly can contribute to the
revitalization of the General Assembly to a certain extent. The key answer
in the revitalization of the General Assembly is a revision of the United
Nations Charter.
Tooth movement rate and anchorage lost during canine retraction: A maxillary and mandibular comparison
Authors: da C. Monini Andre , Gandini Luiz G. , Vianna Alexandre P. , Martins Renato P. , Jacob Helder B.
Published: February 2019

Objectives:

To investigate the canine retraction rate and anchorage loss during canine retraction using self-ligating (SL) brackets and conventional (CV) brackets. Differences between maxillary and mandibular rates were computed.

Materials and Methods:

Twenty-five subjects requiring four first premolar extractions were enrolled in this split-mouth, randomized clinical trial. Each patient had one upper canine and one lower canine bonded randomly with SL brackets and the other canines with CV brackets but never on the same side. NiTi retraction springs were used to retract canines (100 g force). Maxillary and mandibular superimpositions, using cephalometric 45° oblique radiographs at the beginning and at the end of canine retraction, were used to calculate the changes and rates during canine retraction. Paired t-tests were used to compare side and jaw effects.

Results:

The SL and CV brackets did not show differences related to monthly canine movement in the maxilla (0.71 mm and 0.72 mm, respectively) or in the mandible (0.54 mm and 0.60 mm, respectively). Rates of anchorage loss in the maxilla and in the mandible also did not show differences between the SL and CV brackets. Maxillary canines showed greater amount of tooth movement per month than mandibular canines (0.71 mm and 0.57 mm, respectively).

Conclusions:

SL brackets did not show faster canine retraction compared with CV brackets nor less anchorage loss. The maxillary canines showed a greater rate of tooth movement than the mandibular canines; however, no difference in anchorage loss between the maxillary and mandibular posterior segments during canine retraction was found.
Correction of Unilateral Condylar Hyperplasia and Posterior Open Bite with Proportional Condylectomy and Fixed Orthodontic Treatment
Authors: Ha Sang-Woon , Choi Jin-Young , Baek Seung-Hak
Published: February 2019

A 29-year-old female patient with unilateral condylar hyperplasia (UCH) of the left side presented with facial asymmetry, maxillary transverse occlusal plane (MXTOP) cant, posterior open bite, and Class III relationship. Treatment consisted of proportional condylectomy of the left condyle for management of UCH, and fixed orthodontic treatment with intrusion of the left maxillary molars to correct the MXTOP cant and remaining chin point deviation (CPD). Proportional condylectomy with a 14-mm resection of the left condylar head improved the CPD from 11.5 mm to 7.8 mm and resolved the posterior open bite on the left side. However, it produced a Class II relationship on the right and left sides, posterior open bite on the right side, and anterior open bite. Fixed orthodontic treatment with 1.8-mm intrusion of the left maxillary molars using miniscrews corrected the MXTOP cant from 3.5 mm to 1.7 mm, reduced the remaining CPD from 7.8 mm to 3.7 mm, produced counterclockwise rotation of the mandible, and resolved the posterior open bite on the right side and the anterior open bite. After 16 months of total treatment, normal overbite/overjet and Class I relationship were obtained. Treatment results were well maintained after 5 years of retention. For the correction of UCH, it is important to determine the amount of condylar head resection and accurately simulate the correction of CPD and MXTOP cant through intrusion of the maxillary molars.
Estrategia para la implementación de la educación mediática en escuelas públicas de nivel básico / Strategy for the Implementation of the Media Literacy in Basic Level Public Schools
Authors: Guerrero Linares Deyra Melina
Published: February 2019

Las transformaciones que actualmente experimentan la cultura y la comunicación, producto del acelerado desarrollo de la tecnología y de la sociedad de la interacción, obligan a revisar la manera en que niños y adolescentes son educados. Ya no basta con dotarlos de conocimientos para que se desenvuelvan en lo social y en lo laboral, sino que necesitan aprender a vivir y a cuidarse a sí mismos en un entorno de medios digitales y de internet, donde construyen gran parte de su realidad e identidad. Por este motivo, el propósito del presente estudio fue diseñar una estrategia para la implementación de la educación mediática en instituciones educativas públicas de nivel básico del área metropolitana de Monterrey, mediante un diagnóstico de competencias mediáticas en materia de seguridad como un posible primer paso para su aplicación a nivel nacional. La investigación fue de carácter descriptivo, de corte cuasiexperimental y con una metodología mixta. Para recolectar la información se utilizó una encuesta. A partir del total de escuelas públicas primarias de la zona conurbada, se calculó una muestra de 298 planteles, específicamente con estudiantes de cuarto, quinto y sexto grado de primaria. Asimismo, se realizó un cuasiexperimento con tres grupos de control y con tres de tratamiento, con los cuales se aplicaron técnicas de educación popular, como problematización, entrevista simple y video para el cambio social. Los resultados recabados permitieron dibujar el siguiente perfil de hábitos: 95 % de los 15 830 alumnos encuestados emplean redes sociales durante casi dos horas al día, principalmente en casa, por las tardes y en un dispositivo móvil (celular o tableta). Asimismo, 73 % de los participantes indicó que empezaron a emplear estas redes entre los 6 y los 8 años de edad, y que sus portales favoritos son YouTube, Facebook y WhatsApp, donde comparten fundamentalmente videos, fotografías, imágenes y música. Igualmente, de cada 10 niños y adolescentes, 3 no conocen los riesgos que existen en esas plataformas, 4 no saben de las medidas preventivas que deben tomar en ellas, y 6 interactúan en redes solos sin supervisión. Entre los factores que determinan las estadísticas están la escasez de contenidos en dicha materia en los programas académicos, así como que ambos padres trabajen. Por  último, se puede afirmar que las competencias en materia de seguridad se incrementaron en los tres grupos intervenidos gracias a la educación mediática, por lo que se recomienda que se incorpore a las escuelas públicas primarias a través de una estrategia transversal que involucre a los tres poderes de gobierno, los medios de comunicación nuevos y tradicionales, y un plan piloto en las aulas.
La justificación pragmática del liberalismo de John Dewey
Authors: Otero Angelini Diego Alejandro
Published: February 2019

En este artículo presento una reconstrucción de dos argumentos de John Dewey para justificar la democracia liberal. Para hacerlo, primero realizo, en las dos primeras secciones, una exposición de las premisas de los argumentos para, en la tercera sección, mostrar en qué modo la democracia liberal cumple con las condiciones y necesidades planteadas. La primera vía de argumentación está relacionada con la posibilidad de generar las mejores condiciones de indagación para los individuos. Esta vía, que denomino antropológica, me conduce a explicar la naturaleza social del conocimiento humano. La segunda vía, que llamo política, está fundamentada en la concepción de la política que realiza Dewey en The Public and its Problems. Ahí, Dewey reflexiona sobre la comprensión de la política como el ámbito donde surgen intereses que tienen repercusiones públicas. La democracia liberal, como mostraré, es la organización política que permite de mejor modo cumplir con los fines propios de la política y genera las mejores condiciones de indagación para que los individuos puedan prosperar.

Animals that produce offspring are only one deer in 2016, while other animals have no offspring. The utilization of wildlife in TSLHBL is for research, photo taking, visuals and animal attractions. Keywords: ex-situ conservation, wildlife conservation, wildlife parks lembah hijau
Towards a computational prediction for the tumor selective accumulation of paramagnetic nanoparticles in retinoblastoma cells
Authors: Johansen R.J. , Bukhvostov A.A. , Ermakov K.V. , Kuznetsov D.A.
Published: February 2019

Retinoblastoma is a malignant growth affecting retina. An original combination of modified Non-Markov and Gompertzian computational approaches is proven of being a reliable tool for prediction of tumor selective accumulation of the bivalent metal isotopes (25Mg, 43Ca, 60Co, 67Zn, …) — releasing nanoparticles in human retinoblastoma cells. This mathematical model operates with a starting point of the discriminative drug uptake caused by a gap-like distinction between the neighboring malignant and normal cell proliferation rates. This takes into account both pharmacokinetic and pharmacodynamic peculiarities of PMC16, fullerene-C60 based nanoparticles, known for their unique capabilities for a cancer-targeted delivery of paramagnetic metal isotopes followed by an essential chemotherapeutic effect. Being dependent on a tumor growth rate but not on the neoplasm steady state mass, a randomized level of drug accumulation in retinoblastoma cells has been formalized as a predictive paradigm suitable to optimize an ongoing PMC16 preclinical research.

Radionuclide therapy (RNT) is an effective modality for treating multiple metastases in patients with cancer. The list of malignancies that can be managed with RNT expands with the arrival of novel tumoritropic radiopharmaceuticals (RP). A versatile delivery platform capable of carrying various therapeutic and diagnostic radionuclides, as well as vector molecules needed to achieve sufficient specificity to tumor cells and ensure therapeutic efficacy may hold great promise for radiation therapy. The aim of this work was to assess the performance of a delivery system based on the original dendrimer. The dendrimer demonstrated low toxicity in mice (LD50 was 779 ± 111 mg/kg). To study the specificity of the dendrimer to tumor cells and its therapeutic efficacy, we used a nanostructure (NS) composed of the dendrimer itself, the RGD peptide and 188Re (188Re-NS). Lewis lung carcinoma LLC1 was used as a tumor model. The biodistribution analysis revealed that the compound effectively accumulated in the tumor demonstrating a tumor-to-normal ratio >1 (relative to healthy organs and tissues) and retention time of at least 6 hours. Injections of 185 MBq/kg 188Re-NS caused a statistically significant inhibition of tumor growth (p < 0.05) by day 7 following the injection (Т/С = 5%), which remained stable for 6 days. Our findings suggest that the proposed dendrimer is a promising platform for RP delivery.

Authors: Kurapov P.B. , Bakhtenko E.Yu.
Published: February 2019

Due to chemical stability, low toxicity, and relative simplicity of synthesis/modification techniques, gold nanoparticles (NP) enjoy a wide range of biomedical applications, including in vitro diagnostics, targeted drug delivery, contrast-enhanced radiation therapy, and photothermal therapy. The high ratio of the gold NP surface area to their volume facilitates design of complex nanoplatforms for various therapeutic and diagnostic purposes. Unique electrical and optical properties of gold NP known as surface plasmon resonance assist medical diagnosis. In this work we look at the basic methods for gold NP synthesis and modification, including the so-called green chemistry, talk about the pharmacological aspects of their application and highlight their potential as diagnostic agents. We believe that due to their unique properties, gold-based nanoplatforms for targeted drug delivery and theranostics have indisputable advantages over other nanoparticles.

Nous avons jumelé les données liées aux décès (2009 à 2013) tirées des statistiques de l’état civil et des données socioéconomiques de CensusPlus de 2011 à l’échelle de l’aire de diffusion ou de la circonscription sanitaire afin d'étudier les taux de mortalité normalisés selon l’âge (TMNA) et les disparités des TMNA concernant les blessures non intentionnelles et leurs sous-types, notamment les blessures liées aux chutes chez les aînés (65 ans et plus) et les blessures liées au transport, ainsi que le suicide chez les jeunes (15 à 24 ans), ce dernier étant considéré comme une forme de blessure intentionnelle. Nous avons étudié les disparités spatiales et les disparités selon le sexe et nous avons mesuré les disparités relatives et absolues entre les zones moins favorisées et les zones plus favorisées en fonction des quintiles de revenu, de scolarité, d’emploi, de défavorisation matérielle et de défavorisation sociale.

Résultats

Notre étude a mis en évidence d’importantes différences entre les sexes en matière de taux de mortalité attribuable au suicide chez les jeunes, à des blessures liées aux chutes chez les aînés et à des blessures liées au transport, les hommes affichant des taux de mortalité beaucoup plus élevés que les femmes. Nous avons également observé des variations spatiales notables dans les TMNA pour l’ensemble des blessures non intentionnelles à l’échelle de la province. En général, la population vivant dans des zones où les revenus étaient faibles et où la défavorisation matérielle était importante a affiché des taux de mortalité plus élevés que la population vivant dans des zones favorisées.

Conclusion

Le repérage de différences importantes dans les taux de mortalité liée à des blessures intentionnelles et non intentionnelles entre les sexes et en fonction du SSE ouvre des possibilités quant à l’élaboration de stratégies de prévention ciblées pour réduire ces disparités.
Assessing the content and comprehensiveness of provincial and territorial indoor tanning legislation in Canada
Authors: Gosselin Sydney , McWhirter Jennifer E.
Published: February 2019

Introduction

Canadian provincial and territorial governments have enacted legislation in response to health risks of artificial ultraviolet radiation from indoor tanning. This legislation, which differs from jurisdiction to jurisdiction, regulates the operation of indoor tanning facilities. The content and comprehensiveness of such legislation—and its differences across jurisdictions—have not been analyzed. To address this research gap, we conducted a systematic, comprehensive scan and content analysis on provincial and territorial indoor tanning legislation, including regulations and supplementary information.

Methods

Legislative information was collected from the Canadian Legal Information Institute database and an environmental scan was conducted to locate supplementary information. Through a process informed by the content of the legislation, previous research and health authority recommendations, we developed a 59-variable codebook. Descriptive statistics were calculated.

Results

All provinces and one of three territories have legislation regulating indoor tanning. Areas of strength across jurisdictions are youth access restrictions (n = 11), posting of warning signs (n = 11), penalties (n = 11) and restrictions on advertising and marketing targeted to youth (n = 7). Few jurisdictions, however, cover areas such as protective eyewear (n = 4), unsupervised tanning (n = 4), provisions for inspection frequency (n = 4), misleading health claims in advertisements directed toward the general public (n = 2) and screening of high-risk clients (n = 0).

Conclusion

All provinces and one territory have made progress in regulating the indoor tanning industry, particularly by prohibiting youth and using warning labels to communicate risk. Legislative gaps should be addressed in order to better protect Canadians from this avoidable skin cancer risk.
Aperçu - Incidence de la mortalité par intoxication sur l’espérance de vie à la naissance au Canada (2000-2016)
Authors: Orpana Heather , Lang Justin J. , George Diana , Halverson Jessica
Published: February 2019

L’augmentation de la mortalité liée aux opioïdes a contribué à des baisses de l’espérance de vie à la naissance aux États-Unis et en Colombie-Britannique. Nous avons analysé les données nationales sur la mortalité au Canada entre 2000 et 2016 afin de déterminer dans quelle mesure les décès liés aux intoxications avaient influencé l’espérance de vie à la naissance selon le groupe d’âge et le sexe. Entre 2000 et 2016, l’espérance de vie à la naissance a augmenté de presque trois ans, mais la mortalité attribuable aux intoxications accidentelles, dont celles par opioïdes, a réduit cette hausse de 0,16 an. Même si l’espérance de vie à la naissance n’a pas globalement diminué au Canada pendant cette période, les tendances actuelles laissent présager que la crise nationale des surdoses d’opioïdes va continuer à amoindrir les gains relatifs à l’espérance de vie.

Published: February 2019

The main objectives of this research are to describe the obedience towards the regulation of timeliness financial report submission and to analyze the influence of financial performance and corporate governance structure to timelines of financial report submission. The research questions are tested by running Analysis of Variance (Anova) and two logistic regressions. Timelines (measured by dummy variable, 1 if the company comply financial report submissioni.e. before and at 31 of March, while 0 for delayed submission) is the dependent variable both in Anova and in logistic regression. The independent variables in logistic regression consist of EAT, ROA, ROE, Leverage, concentration ownership by domestic institution, number of the Board of Directors, number of the Board of Commissioners and Industry Classification. The first main result of this study is that there is an increasing of timelines obedience. This suggests that the obedience of listed companies towards the regulation of timelines is increasing form time to time. The second main result of this study is that there is an influence of profitability (ROA), leverage and corporate governance structure (ownership concentration by Domestic Institution/HI_DOM) to the probability of timelines financial report submission. The positive and negative sign of ROA and leverage respectively, suggest that higher ROA and lower leverage tend to obey the regulation of timelines. The negative sign of HI_DOM suggest that the lower ownership concentration by Domestic Institution tend to obey the regulation of timelines.
