Gestão por Perversão: A crise econômica invade o Ambiente Organizacional e abre as portas ao Assédio
Authors: Azevedo Ismael De Mendonça
Published: November 2016

A crise econômica torna a expectativa de vida financeira de uma organização algo incerto como também o ambiente interno da organização se torna instável e inseguro. Com o intuito de se manterem vivas, ativas e representativas, as organizações não perdem a audácia no momento em lançam novas metas para seus colaboradores, por vezes inalcançáveis, haja vista a instabilidade econômica. O objetivo deste trabalho é relatar a percepção das experiências de assédio moral vivenciadas por uma equipe de trabalhadores terceirizados de uma Instituição Bancária Federal. Para alcançar esse objetivo, revisou-se a bibliografia que define o clima organizacional e o assédio moral. A coleta de dados foi efetuada a partir de conversas informais com membros da equipe atuante no estado do Rio Grande do Norte, bem como observação e leitura de e-mails enviados e recebidos pelos mesmos com seus superiores diretos e indiretos. Finalizando com uma reflexão da perversão trazida pela crise ao ambiente organizacional.
A Gravidez não planejada de mulheres atendidas no pré-natal das Unidades Básicas de Saúde
Authors: Rodrigues Clícia Dias Da Silva , Lopes Arianna Oliveira Santana
Published: November 2016

A gravidez não planejada é toda a gestação que não foi programada, ou que foi causada por uma necessidade insatisfeita de contracepção. Os desdobramentos de sua ocorrência, atualmente são considerados grandes demandas para a saúde pública, principalmente entre as mulheres mais jovens e nas famílias em vulnerabilidade social (FINOTTI, 2015). Tendo em vista estes aspectos, o objetivo deste estudo foi  averiguar os aspectos relacionados a gravidez não planejada em mulheres atendidas no pré-natal, apresentando a importância da atuação do enfermeiro no tocante a prevenção, orientação e controle, em unidades de saúde de cidades da região sudoeste da Bahia. Trata-se de um estudo exploratório e descritivo com corte transversal analítico, cuja abordagem é quantitativa, onde os dados serão oriundos da aplicação de um questionário estruturado, dividido em 20 questões, que versam sobre as características socioeconômicas e demográficas, e da história contraceptiva e gestacional da mulher. A pesquisa transcorreu entre os meses de julho e setembro de 2016, frente a uma amostra de 100 mulheres gravidas. A análise dos dados do estudo foi realizada de forma descritiva, utilizando a tabulação de dados, com média, desvio padrão, porcentagem e frequência através do programa Excel 2013 que em seguida foram submetidos ao software SPSS 23.0. Para tanto, um cálculo amostral foi realizado baseando-se no erro amostral de 5% e no nível de confiança de 90%, dentre as mulheres entrevistadas. O resultado desse estudo evidencia que as mulheres que apresentam gravidez indesejada, em sua grande maioria, utilizavam métodos contraceptivos de forma equivocada, fato que causou a gravidez. Além disso, aponta-se para uma precária participação das mulheres no planejamento familiar e também na visitação das equipes de saúde da família. Esse estudo conclui assim, que essa utilização errônea dos métodos contraceptivos estão relacionados diretamente com a falta de informação e desconhecimento sobre o método, devido a aspectos socioeconômicos, bem como a ineficiência do sistema de saúde e suas instituições, que não conseguem fornecer a instrução necessária a população feminina sobre a prevenção da gravidez não planejada.

Prophetic Critiques of Colonial Agricultural Schemes: The Case of Alinesitoué Diatta in Vichy Senegal
Authors: Baum Robert M.
Published: November 2016

This article examines the prophetic movement of Alinesitoué Diatta, focusing on her teachings related to Diola agriculture and French colonial development plans. By looking at her teachings in relation to rice agriculture and French support of a new cash crop, peanuts, one can see both the religious significance of agriculture in Diola society and the importance of religious sources of indigenous knowledge about agricultural innovations. Her opposition to Vichy French agricultural initiatives contributed to their decision to arrest and exile her to Timbuctou, where she died of scurvy within a year of her deportation.
The Life and Experiences of Sa`id Ibn Hayatu, a Mahdist Leader: New Findings from the Buea Archive
Authors: O’Rourke Harmony , Salau Mohammed Bashir
Published: November 2016

This article examines records from the Buea National Archives in Cameroon to illuminate our understanding of Shaykh Sa`id ibn Hayatu’s experience in exile after he was arrested for allegedly planning to overthrow the colonial regime in Northern Nigeria in 1923. Although previous studies have analyzed Sa`id’s activities and biography, this article is the first publication to present information from Buea, the site of his exile from 1924 to 1945. These documents provide details on Sa`id’s household in Buea, the family’s financial situation, Sa`id’s primary complaints while in exile, letters from Sa`id to the colonial administration and contacts in Northern Nigeria, as well as correspondence among colonial officials about Sa`id and Mahdism. Evidence from this new archival source helps to answer two questions that have puzzled historians of West Africa for several decades, namely why Sa`id’s detainment lasted so long and what conditions finally ended his and his dependents’ isolation. This article argues that British perceptions of Mahdist danger facing Northern Nigeria after 1924 significantly influenced the contours of Sa`id’s exile, as did their perceptions of him as a symbol of the potent history and legacy of Mahdism in the region. The article also suggests that tensions between, on the one hand, Northern Nigerian officials facing real and imagined Mahdist threats and, on the other hand, administrators in Buea who personally encountered Sa`id on a regular basis, framed colonial state policies regarding the length and termination of Sa`id’s exile.
Secrets of West African Slave Ancestry: Fante Strategies of Silence and the Didactic Narrative in Ghanaian Literature
Authors: Smith Victoria Ellen
Published: November 2016

Akan customary law prohibits mention of slave ancestry and it is publicly claimed that indigenous slavery has been forgotten. In practice, customary law enables inheritance to be contested on grounds of slave ancestry and the descendants of slaves are stigmatized. In response, strategies of silence conceal knowledge. The example given is Ntam Kɛse, a reminiscent oath that sanctions communication between Fante family members by providing the metacommunicative instruction not to tell nonmembers. This locates the memory of indigenous slavery in Bellman’s “paradox of secrecy.” The thesis of this article is that strategies such as oath taking are being disrupted by nonmembers and that Ghanaian literature offers a solution to engagement with the taboo subject. It is argued that works by Kwadwo Opoku-Agyemang, Ama Ata Aidoo, and Ebow Daniel are didactic because they develop an understanding of West African slave ancestry by representing the history of indigenous slavery as a secret.

Authors: Lantos Csaba , Jenes Barnabás , Bóna Lajos , Cserháti Mátyás , Pauk János
Published: November 2016

This is the first study to report an efficient anther culture (AC) method for spelt wheat, which has an increasing importance not only in applied research but also in organic farming and changing nutritional standards. In this study, an efficient AC protocol has been described for ‘GK Fehér’ spelt wheat. The number of AC-derived embryo-like structures (ELS) was 62.2/100 anthers, from which we were able to regenerate 30.6 green plantlets per 100 anthers. The percentage of green plantlets production was 89.0% among the regenerated plantlets, while the phenomenon of albinism was restricted (3.8/100 anthers). Altogether, from AC of ‘GK Fehér’ 306 green plantlets were producedin vitroand 241 plants were acclimatized to the greenhouse conditions. Based on ploidy level analyses, 83 spontaneous doubled haploid (DH) plants were produced (8.3 DH plants/100 anthers), so the percentage of spontaneous rediploidization was 34.4%. The spontaneous DH plants produced fertile spikes, while a few seeds were harvested from seven partially fertile plants.

Published: November 2016

The male-specific DNA markers are very useful in molecular sexing of non-flowering plants and seeds of dioecious species. In this paper we identified ten Y chromosome-specific RAPD primers suitable for identification of male plants in three Cannabaceae species with sex chromosomes (Humulus lupulus, XX/XY; H. japonicus, XX/XY1Y2; Cannabis sativa, XX/XY). Basing on the nucleotide sequence of the OPJ-09 RAPD product we developed the HJY09 SCAR marker, which is very efficient in sexing of Japanese hop.
Ozone Effect On the Properties of Aramid Fabric
Authors: Wang Yan , Wiener Jakub , Militky Jiri , Mishra Rajesh , Zhu Guocheng
Published: November 2016

The limitation of aramid fiber is its surface property, which results in its very poor interfacial adhesion to most of commercial resins. In order to improve the surface property of the aramid fiber, ozone treatment was carried out in this work. The aramid fabrics were evaluated in terms of surface morphology, wicking effect, tensile property, and ball bursting test. The results showed that the surface morphology of aramid fabrics did not undergo an obvious change; the wicking effect increased slightly with an increase in ozone treatment time; the tenacity and elongation of aramid fibers and fabrics did not significant change after ozone treatment, but the tenacity and elongation of aramid yarns showed significant improvement after ozone treatment, and increased with the increase of ozone treatment time; the ball bursting load and penetration displacement had a slight increase as well after ozone treatment. Therefore, ozone treatment could be one method to improve the surface property of the aramid fiber.
A Time-Stepping DPG Scheme for the Heat Equation
Authors: Führer Thomas , Heuer Norbert , Sen Gupta Jhuma
Published: November 2016

We introduce and analyze a discontinuous Petrov–Galerkin method with optimal test functions
for the heat equation. The scheme is based on the backward Euler time stepping and uses an ultra-weak
variational formulation at each time step. We prove the stability of the method for
the field variables (the original unknown and its gradient weighted by the square root
of the time step) and derive a Céa-type error estimate. For low-order approximation spaces
this implies certain convergence orders when time steps are not too small in comparison with mesh sizes.
Some numerical experiments are reported to support our theoretical results.
Factorized Schemes of Second-Order Accuracy for Numerically Solving Unsteady Problems
Authors: Vabishchevich Petr N.
Published: November 2016

Schemes with the second-order approximation in time are considered for numerically solving the Cauchy problem
for an evolutionary equation of first order with a self-adjoint operator.
The implicit two-level scheme based on the Padé polynomial approximation
is unconditionally stable. It demonstrates good asymptotic properties in time
and provides an adequate evolution in time for individual harmonics of the solution (has spectral mimetic (SM) stability).
In fact, the only drawback of this scheme is the necessity to solve
an equation with an operator polynomial of second degree at each time level.
We consider modifications of these schemes, which are based on solving equations with operator polynomials of first degree.
Such computational implementations occur, for example,
if we apply the fully implicit two-level scheme (the backward Euler scheme).
A three-level modification of the SM-stable scheme is proposed. Its unconditional stability
is established in the corresponding norms. The emphasis is on the scheme, where the numerical algorithm
involves two stages, namely, the backward Euler scheme of first order at the first (prediction) stage
and the following correction of the approximate solution using a factorized operator.
The SM-stability is established for the proposed scheme. To illustrate the theoretical results of the work,
a model problem is solved numerically.

Authors: Abbas Aumber , Abbas Saleem , Wang Xianli
Published: November 2016

Nanoporous copper (NPC), a representative type of nanostructured materials, holds an extensive ability to generate propitious potential for a broad range of highly promising applications. Especially, with the advancement in fabrication techniques, NPC with numerous special and superior properties, such as unique pore structure, large surface-to-volume ratio, enlarged specific surface area, and high electrical and thermal conductivities, has boosted the interest to explore its electrochemical properties and extended its promising applications in energy, sensing, actuation, and catalytic systems. Therefore, timely updates of such a type of material are highly demanding and appealing for a broad audience. This review summarizes the latest advances in the development of NPC with a special focus on synthesis methods and state-of-the-art electrochemical applications such as electrocatalysts, sensors, and energy conversion/storage systems. The important scientific disputes and future research directions are also presented.
CYP2D6 variability in populations from Venezuela
Authors: Moreno Nancy , Flores-Angulo Carlos , Villegas Cecilia , Mora Yuselin
Published: November 2016

CYP2D6 is an important cytochrome P450 enzyme that plays an important role in the metabolism of about 25% of currently prescribed drugs. The presence of polymorphisms in the CYP2D6 gene may modulate enzyme level and activity, thereby affecting individual responses to pharmacological treatments. The most prevalent diseases in the admixed population from Venezuela are cardiovascular and cancer, whereas viral, bacterial and parasitic diseases, particularly malaria, are prevalent in Amerindian populations; in the treatment of these diseases, several drugs that are metabolized by CYP2D6 are used. In this work, we reviewed the data on CYP2D6 variability and predicted metabolizer phenotypes, in healthy volunteers of two admixed and five Amerindian populations from Venezuela. The Venezuelan population is very heterogeneous as a result of the genetic admixture of three major ethnical components: Europeans, Africans and Amerindians. There are noticeable inter-regional and inter-population differences in the process of mixing of this population. Hitherto, there are few published studies in Venezuela on CYP2D6; therefore, it is necessary to increase research in this regard, in particular to develop studies with a larger sample size. There is a considerable amount of work remaining before CYP2D6 is integrated into clinical practice in Venezuela.

Fungi are a group of microbes that are found with
particular incidence in the indoor environment. Their direct
toxicity or capability of generating toxic compounds
has been associated with a large number of adverse health
effects, such as infectious diseases and allergies. Given
that in modern society people spend a large part of their
time indoors; fungal communities’ characterization of this
environmental compartment assumes paramount importance
in the comprehension of health effects. House dust is an easy to obtain, time-integrative matrix, being its use
in epidemiological studies on human exposure to environmental
contaminants highly recommended. Furthermore,
dust can carry a great variety of fungal content that undergoes
a large number of processes that modulate and
further complexify human exposure. Our study aims to
identify and quantify the fungal community on house dust
samples collected using two different methodologies (an
approach not often seen in the literature): active (vacuum
cleaner bags) and passive sampling (dust settled in petri
dishes). Sampling was performed as part of the ongoing
6 × 60 × 6 Project in which six houses from Covilhă (Portugal),
with building dates representative of six decades,
were studied for a period of sixty days.

Synthesis and characterization of 1,3,4-thiadiazole-2,5-dithio crown ethers
Authors: Çiçek Baki , Onbaşıoğlu Zekai
Published: November 2016

Hetero-crown ethers (ligands I–IV) containing 1,3,4-thiadiazole-2,5-dithiol (bismuthiol) were synthesized and fully characterized. The ligands were prepared by a nucleophilic substitution (SN2) reaction of the appropriate ethylene glycol dihalide derivatives with 1,3,4-thiadiazole-2,5-dithiol dipotassium salt under highly diluted conditions, and subsequent ring closure. Complexation constants and selectivity factors for these heterocyclic ligands in dichloromethane or chloroform were determined by ion-pair extraction from an aqueous solution containing Ag+, Ca2+, Zn2+, Fe3+, Cr3+, Co2+, Cd2+, Mg2+, Pb2+, Ni2+, Cu2+, Mn2+, Na+ and K+. These ligands could be applied as metal sensors and used to separate metals from various mixtures.

For the first time L. danuvii has been found with plants of agricultural importance (Malus domestica Borkh., Pyrus sp. and Rubus idaeus L.). Additionally, this nematode species has been found for the first time in localities with relatively dry conditions (on the tops of the hills), which are distant from banks of rivers – biotopes from which it has been recorded previously.
Investigating social support patterns of single mothers from a social network perspective
Authors: Lumino Rosaria , Ragozini Giancarlo , Vitale Maria Prosperina
Published: November 2016

In the present study, we discuss how social network analysis approach can be fruitful exploited to study social support within family studies. An ego-centred network approach is adopted within a case study about social support networks of low income single mothers living in a city of southern Italy. We address three main issues. First, we aim to describe and explore the structure of social relationships that single mothers activate in order to obtain different kind of supports. Second, we investigate the main factors that affect the amount and variety of resources embedded in the single mothers’ support networks. Third, we analyse the relationship between the received social support embedded in the ego network and the support perceived by mothers. Beyond the description of composition and structure of ego-centred networks through network measures and factorial methods, a series of regression models was estimated to assess factors explaining received and perceived support of single mothers.
Women’s Social Capital in Academia: A Personal Network Analysis
Authors: Barthauer Luisa , Spurk Daniel , Kauffeld Simone
Published: November 2016

Developmental networks are ego-centered networks, and were found to be beneficial for career success and advancement. Especially in academia, the benefits of developmental networks are critical due to limitations in career stability, and its up-or-out character. Overall, they facilitate career success and advancement by providing access to social capital, which is more or less attainable depending on certain structural network characteristics. Diverging access to social capital for women and men is well known, however, little is known about developmental networks of female and male academic staff. Therefore, this study investigated cohesion and brokerage as indicators for access to social capital to explore gender differences. The sample consisted of n = 594 ego-networks of PhDs and postdocs, working at German universities and research institutes. Cohesion was measured by density and degree; brokerage by effectiveness and constraint. Results revealed that based on Coleman’s cohesion theory (1988, 1990), female researchers showed less access to social capital through less dense networks, but bigger ones implying more social capital. Moreover, based on Burt’s brokerage theory (1992, 2005), female researchers showed, against our assumptions, more brokerage social capital by showing greater effectiveness, and less constraint. Results provide insight into men’s and women’s access to social capital.
Diffusion of Islam in the United States: Comparative Personal Conversion Social Networks
Authors: Erin Şakin
Published: November 2016

Conversion is one of the ways in which religion diffuses in society. Different than other diffusions, such as adopting a new technology or a fad, religious adoption can be riskier since it entails a life changing transition thereby making it a complex contagion. This study investigates whether Islam diffuses through weak ties or strong ties. By comparing conversion cases in Michigan, where there is a larger Muslim community, and Kentucky, where there is a less tangible Muslim community, I argue Islam is more likely to diffuse through what I call recessive or dominant weak ties in Michigan, whereas it is more likely to diffuse through strong ties in Kentucky. I collected personal social networks of 18 individuals who converted to Islam living in Michigan and 12 living in Kentucky. I found the research participants through mosques located in several cities in Michigan, including Ann Arbor, Ypsilanti, Flint, Detroit, Dearborn, and Canton, and two cities in Kentucky: Lexington and Louisville. Having investigated a set of egocentric conversion networks from both Michigan and Kentucky, I found that the existence of a Muslim community and how it is perceived by mainstream society is an ultimate factor in determining the strength of a tie to other Muslims. Thus, Islam is more likely to diffuse through weak ties where there is a Muslim community, but it is more likely to diffuse through strong ties where there is no such community.
A Personal Network Approach in Mixed-Methods Design to Investigate Transnational Social Protection
Authors: Bilecen Başak
Published: November 2016

Research on the cross-border practices that underpin the spatial dimension of personal relationships involves also the study of protective resources (e.g. care, information exchange and financial assistance). However, studies that examine such transnational practices within migrants’ personal networks face methodological challenges at both the data collection level and the data analysis level. For a comprehensive analysis of migrants’ life worlds, new methodological approaches to transnational practices and resource flows within personal networks are essential. Thus, this article aims to illustrate ways to study social protection by empirically capturing such practices. In addition to demonstrating that the combined use of personal network analysis and qualitative interviews is a fruitful approach, this study used a mixed-methods design contributing to capture the interrelationship between transnational social protection patterns and migrants’ strategies, as well as their meanings.
Makroökonomische Nachrichten und die Reaktion des 15-Sekunden-DAX: Eine Ereignisstudie zur Wirkung der ZEW-Konjunkturprognose / Announcement of Business Cycle Forecasts and the Reaction of the German Stock Market
Authors: Entorf Horst , Steiner Christian
Published: November 2016

We study the response of the German stock market index DAX to the announcement of macroeconomic business cycle forecasts. Returns are computed using high-frequency data observed for 15-second intervals. Publications of macroeconomic US indicators at 2:30 p.m. (CET) have temporary and opening of the New York Stock Exchange at 3:30 p.m. (CET) have permanent effects on the volatility of the German DAX. Moreover, the intraday volatility of the DAX index has a U-shaped form, which has also been identified for other international stock markets. Major reactions of both returns and volatility occur within the first 15 to 60 seconds after the announcement, revealing a high efficiency of the German capital market. Unanticipated shocks cause asymmetric stock market returns: “good” news lead to more pronounced reactions than “bad” news. Moreover, there is evidence of mean reversion and calm-before-thestorm effects. Finally, serial correlation of returns is found to be a potentially spurious result of non-anticipated announcements of macroeconomic news.

In simple overlapping-generation models, the young save by purchasing assets from the old, who in turn finance their consumption by spending the proceeds. If household saving of a shrinking younger generation falls short of planned, constant asset sales by the old generation, asset prices might drop. This note argues that the above asset-meltdown argument holds only in case of a strict cash-in-advance constraint in a model with sharp demarcations between periods. Here, the shrinking size of the young generation establishes a supply-side constraint for production, and the old cannot realize the planned value of asset sales so that goods prices cannot be bidden up. In a more realistic setting of simultaneous and slow changes, only some flexibility and elasticity of the financial system is needed to resolve the cash-in-advance constraint. Excess goods demand then will produce rising prices. Then, necessarily additional savings (in the form of undistributed profits) arise as a flow-of-funds effect, which in turn help to maintain asset market equilibrium. Asset prices nevertheless might fall because of rising interest rates if monetary policy reacts to inflationary tendencies (if goods-supply constraints persist). But this line of reasoning is different from the shortage-of-saving myth.
Investigation of GPS draconitic year effect on GPS
time series of eliminated eclipsing GPS satellite
data
Authors: Allahverdi-zadeh A. , Asgari J. , Amiri-Simkooei A.R.
Published: November 2016

GPS draconitic signal (351.6 ± 0.2 days) and its
higher harmonics are observed at almost all IGS products
such as position time series of IGS permanent stations.
Orbital error and multipath are known as two possible
sources of these signals. The effect of Earth shadow crossing
of GPS satellites is another suspect for this signal. Up
to now there is no serious attempt to investigate this dependence.
AMATLAB toolbox is developed and used to determine
the satellites located at the earth shadow. RINEX
observation files and precise ephemeris are imported to
the toolbox and a cylindrical model is used to detect the
shadow regions. Data of these satellites were removed
from the RINEX observation files of three IGS permanent
stations (GRAZ,ONSAandWSRT) and new RINEX observation
fileswere created. The time span of these data is about
11 years. The new and original fileswere then processed using
precise point positioning (PPP) method to determine
position time series, for further analysis. Both the original
and new time series were analyzed using the least squares
harmonic estimation (LS-HE) in the following steps. The
1st step is the validation of the draconitic harmonics signature
in the original position time series of the three stations.
The 2nd step does the same for the new time series.
It confirms that the power spectrum at the draconitic signals
decreases to some extent for the new time series. The
difference between the original and new time series (difference
between all three position quantity (X, Y and Z)) is
then analyzed in the 3rd step. Signature of the draconitic
harmonics is also observed to the differences. The results
represent that all eight harmonics of GPS draconitic period
do exist at the residuals and mainly they decrease. All of
the three stations were then processed together using the
multivariate LS-HE method. At the 4th step, the difference
of the spectral values between the original time series and
new times serieswere analyzed. Decreasing of the spectral
values at most harmonics (e.g. 1st, 2nd, 4th, 6th, 7th and 8th)
represents the effect of removing satellite observations at
shadow of the earth on draconitic harmonics. At least, five
harmonics among seven shows the amelioration of results
(draconitic error reduction) after removing the earth shadowed
data from RINEX raw data. The results show that the
draconitic year’s component of data is in part due to eclipsing
satellites.
The Personalisation of Politics at the Local Level in Poland and Selected Central and Eastern European States: A Contribution to the Research
Authors: Antkowiak Paweł , Schefs Łukasz
Published: November 2016

Images about politics take a specific form in the imagination of the electorate, eliciting specific associations and thus becoming a source of attitudes and influencing election preferences. At the same time, the increasing importance of politicians’ perceived personality traits and images has been observed. Empirical studies of politicians’ personalities provide one of the more effective tools for studying the basic features of the personalisation of politics, including at a local level. Such studies involve the measurement of citizens’ perceptions of politicians’ personality traits. This article seeks to systematise key concepts and provide an introduction to conducting advanced empirical research in this area.
Attitudes towards the Government’s Remembrance Policy in Poland: Results of an Experimental Study
Authors: Wawrzyński Patryk , Schattkowsky Ralph
Published: November 2016

The paper presents the results of an experimental study of Polish students’ attitudes towards their government’s remembrance policy (or, in other words, the intentional narration and interpretation of the past by the government). It includes four parts: a justification of why remembrance is a significant political asset in post-Communist Poland; a classification of remembrance policy instruments; a presentation of general results of the study; and a discussion of participants’ attitudes to particular policy instruments. In our assessment of the general results, we discuss three types of collected data: the results of the initial measurement of attitudes; the results of measurement after the manipulation of emotions (neutral vs. positive vs. negative) and commitment (no commitment vs. low commitment); and the results in terms of attitude change. In the section on attitudes to particular instruments, we compare participants’ support for different commemorative actions with their support for the governments’ dominant role in the popularising of remembrance narratives. The study’s results lead us to formulate three conclusions about the relationships between attitudes to the policy and Polish political culture.

lithium ion conducting polymer electrolyte is one of the essential components of modern rechargeable lithium batteries because of its good interfacial contact with electrodes and effective mechanical properties. A solid lithium ion conducting polymer blend electrolyte is prepared using poly (vinyl acetate) (PVAc) and poly (methyl methacrylate) (PMMA) polymers with different molecular weight percentages (wt%) of lithium chloride (LiCl) by the solution casting technique with tetrahydrofuran as a solvent. The polymer electrolytes were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), Thermogravimetry (TG), AC impedance spectroscopy and ionic transport measurements. XRD and FTIR studies confirm the amorphous nature of the polymer electrolyte and the complexation of salt with polymer. The thermal behavior of polymer electrolytes has been studied from DSC and TG. The highest conductivity obtained using AC impedance spectroscopy is 1.03×10−5 Scm−1 at 303 K for 70 wt%PVAc:30 wt%PMMA:0.8 wt% of LiCl polymer-salt complex. The plasticizer ethylene carbonate (EC) and nanofiller titania (TiO2) were added to the optimized high conducting blend polymer electrolyte. An enhancement in conductivity by one order of magnitude was observed for the plasticized 70 wt%PVAc-30 wt%PMMA-0.8 wt% LiCl polymer electrolyte at ambient temperature. The ionic conductivity value obtained using AC impedance spectroscopy for the plasticized 70 wt%PVAc-30 wt%PMMA-0.8 wt% LiCl polymer electrolyte was 1.03×10−4 Scm−1. The highest conductivity obtained for 70 wt%PVAc-30 wt%PMMA-0.8% LiCl-6 mg TiO2 was 4.45×10−4 Scm−1. Dielectric properties of polymer films are studied and discussed. The electrochemical stability of 1.69 V and 2.69 V was obtained for 70 wt%PVAc-30 wt%PMMA-0.8% LiCl and 70 wt%PVAc-30 wt%PMMA-0.8% LiCl-6 mg TiO2 polymer electrolytes, respectively, using linear sweep voltammetry. The value of Li+ ion transference number was estimated by the DC polarization method and was found to be 0.99 for the highest conducting 70 wt%PVAc-30 wt%PMMA-0.8 wt% LiCl-6 mg TiO2 nanocomposite polymer electrolyte.

Spatial Economics Model Predicting Transport Volume
Authors: Lu Bo
Published: November 2016

It is extremely important to predict the logistics requirements in a scientific and rational way. However, in recent years, the improvement effect on the prediction method is not very significant and the traditional statistical prediction method has the defects of low precision and poor interpretation of the prediction model, which cannot only guarantee the generalization ability of the prediction model theoretically, but also cannot explain the models effectively. Therefore, in combination with the theories of the spatial economics, industrial economics, and neo-classical economics, taking city of Zhuanghe as the research object, the study identifies the leading industry that can produce a large number of cargoes, and further predicts the static logistics generation of the Zhuanghe and hinterlands. By integrating various factors that can affect the regional logistics requirements, this study established a logistics requirements potential model from the aspect of spatial economic principles, and expanded the way of logistics requirements prediction from the single statistical principles to an new area of special and regional economics.

Published: November 2016

In order to monitor and correct the meteorological factors of the spring gravity meter, the characteristics of the time varying gravity changes caused by meteorological factors were analyzed. Kunming GS15 gravity meter from 2007 continuous gravity observation has been carried out with the sampling rate of the pressure observation. In this study, we first compare the effects of 4 types of gravity meter and 3 different types of stations on the gravity observed seasonal gravity signals. It is indicated that the observed seasonal gravity signal of the cave is only 1/10, and there is a constant temperature and constant pressure device. Compared with the same time, the gravity signal of the gravity signal is about 100 times smaller. The influence of the pressure load of the gravity meter is tested by using the theory of pressure. The results show that only the actual value of 2cpd - 3cpd pressure load varies from -0.395 to -0.280×10-8ms-2 , and the 1cpd to 1 cpm periodic partial type gravity meter is also in accordance with the law of gravity and air pressure. And with the characteristics of time lag. In this paper, the nonlinear zero drift parameters of the linear regression model with time lag and the time series of the GS15 gravity meter are used to simulate the nonlinear zero drift parameters of the gravity meter. The results show that the gravity signal contains time lag 35 hours, and the air pressure admittance is 0.8 × 10-8ms-2/mbar. The correlation can reach 79%. The gravity changes signal and satellite gravity as well as the gravity water load signal of the land water model are the same as the gravity water load signal in the autumn as the minimum value, and the seasonal variation of the maximum value of gravity in summer.

By using the advantages of copula function to solve the related issues, this paper proposes the mechanical system reliability model based on copula function. And makes a detailed research for the serial and parallel mechanical system model and gets their reliability function respectively. Finally, the application research is carried out for serial mechanical system reliability model to prove its validity by example. Using Copula theory to make mechanical system reliability modeling and its expectation, studying the distribution of the random variables (marginal distribution) of the mechanical product’ life and associated structure of variables separately, can reduce the difficulty of multivariate probabilistic modeling and analysis to make the modeling and analysis process more clearly.
