Authors: Wang Shiow-Luan , Hou Yung-Tsung , Kankham Sarawut
Published: August 2019

The proliferation of Internet technology and balance of composition in major feature of many visual products have been advantageous for businesses and changed the distribution channels through which industries reach their consumers. The intensive development of Internet technology and the increasing popularity of online shopping have further changed customers’ purchasing behaviors and the methods by which companies disseminate their video advertisements. The main research question that this study intends to answer is, “What do users do when a YouTube advertisement appears? Do they avoid or confront them?” The aim of this study is to explore the perceptions and related behaviors of international purchasing and consumers’ trust of YouTube advertisements. Statistical analyses focus on the demographics of a sample population in Thailand. The findings are based on data obtained by a questionnaire, the results of which were analyzed by t-test and multiple regression. The results indicate that YouTube advertising has a significant effect on behavioral trends. Moreover, the subjects in the sample reported that they are more likely to avoid YouTube ads than confront them. The study subjects have low satisfaction with YouTube advertising, and males have significantly lower satisfaction than females. This study also analyzes the reliability of trust perception toward purchasing. The results indicate that the reliability is greater than 90% at an α level of 5% and a 95% confidence interval.

Published: August 2019

Some immune escape mutants of H9N2 virus and the corresponding mutations in hemagglutinin (HA) have been documented, but little is known about the impact of a single mutation on the antigenicity and pathogenesis of H9N2. In this study, seven critical sites in HA associated with the antigenicity were identified and the effects of a HA mutation (N166D) derived from a H9N2 escape mutant (m3F2) were investigated. Although N166D did not significantly affect viral replication in Madin–Darby canine kidney (MDCK) cells and viral shedding in the larynx and cloaca of chicken, N166D attenuated the pathogenesis of the virus in mice. Compared to the rescued RgPR8-H9_166D, RgPR8-H9_166N caused greater body weight loss and higher viral titers in the lungs of the infected mice. Moreover, hemagglutination inhibition (HI) assay for the sera from the chickens infected with wild type H9N2 and mutant m3F2 showed that N166D mutation could result in weak antibody response in chickens. Considering the field strains of H9N2 with N166D mutation are frequently isolated in the countries with H9N2 vaccination, the findings that the single mutation in HA, N166D, affected both the antigenicity and pathogenesis of H9N2 highlight the significance of surveillance on such mutation that may contribute to the failure of H9N2 vaccination in the field.

Published: August 2019

In order to build a good and secure society, people should believe in civic engagement and participation. Citizenship education should begin at a very young age and continue into adulthood as a process of lifelong learning. Hence, the present paper aims at examining the extent to which EFL textbooks at secondary level are civically oriented using a descriptive content analysis. It is also meant to identify how the concept of the "good citizen" is implemented through course units of the textbook.  The paper will draw important implications for syllabus designers, and teachers.  Policy makers are also required to incorporate an effective implementation approach of civic education in Moroccan National textbooks so that future generations will be aware of their rights, responsibilities and their full commitment toward the community at large.
THE POETICS OF REALISM AND THAT OF SOCIALIST REALISM
Authors: Sulko Lirim
Published: August 2019

When discussing the poetics of realism, we consider the fact that the indisputable dominant literary genre is the novel which, since the 18th century, in the context of  romantization, turned out to be a suitable form for expressing the basic contradiction of romantization, the one between  the individual and  the community, where the hero is a direct expression of the archetype of the  romantic individual. Later, in the nineteenth century, the novel became the main literary genre in Western literature as well, which, through the development of the psychological novel (the non-psychological, pre-psychological novel, is only a form of epic or satire) becomes an expression of the individualist vocation characterizing western civilization, when the latter has finally passed from the traditional (holistic) society to modern (individualist) society. Even in the poetics of socialist realism, the novel remains the most favorite lyrical genre (in addition to poems and lyrical poetry) being directly linked to the base  paradigm of the communist regime, which was the creation of a 'New Man’.

Authors: Bhakat Champak
Published: August 2019

The raw milk quality has increasing importance for producer and consumer as it is directly related to processing, production and price. The aim of present study was to determine the relationship among intramammary infection (IMI) and raw milk parameters in Jersey crossbred cows. Total 24 lactating Jersey crossbred cows were randomly selected and representative animal wise morning milk samples were collected in monthly interval for four month. The level of somatic cell count (SCC) and milk parameters (fat (%), solid non-fat (%) and pH) was estimated from the collected sample. Test day milk yield for individual animals was also recorded and then the data obtained were statistically analyzed. A significant (P<0.01) negative correlation of Log10SCC with test day milk yield, fat and SNF percentage was found, while, milk pH was highly positive correlated with Log10SCC in milk. The mean±SE values of milk yield, fat and SNF were significantly (P<0.01) lower in subclinical infected group except for SCC and pH, which were higher in subclinical infected group. It can be concluded that IMI and higher SCC adversely affect the milk production and raw milk quality parameters and these parameters can be used as useful indicator as complimentary to SCC to monitor udder health and for early diagnosis of subclinical mastitis at dairy farm.Keywords: Intramammary Infection, Jersey crossbred, Raw milk Parameter, Relationship

Published: August 2019

We studied the synthesis of fluorine-bearing species by the irradiation of CO ice containing a small proportion of CH3F at 10 K with vacuum ultraviolet (VUV) light and energetic electrons. Photolysis of the ice sample with VUV light with a wavelength of 121.6 nm produced mainly fragments of CH3F, whereas both carbon oxides and fragments of CH3F were generated by irradiation with broadband VUV light. In contrast, electron irradiation of a similar ice sample generated not only those products observed in the photolysis experiments, but also complex organic hydrocarbons and fluorinated (carbon) oxides. This observation of the distinctive effect of the formation of different products by different excitation sources provides an insight into the energetic processes occurring in interstellar icy dust grains.

We present EMPIRE, an IRAM 30 m large program that mapped λ = 3–4 mm dense gas tracers at ∼1–2 kpc resolution across the whole star-forming disk of nine nearby massive spiral galaxies. We describe the EMPIRE observing and reduction strategies and show new whole-galaxy maps of HCN(1−0), HCO+(1−0), HNC(1−0), and CO(1−0). We explore how the HCN-to-CO and IR-to-HCN ratios, observational proxies for the dense gas fraction and dense gas star formation efficiency, depend on host galaxy and local environment. We find that the fraction of dense gas correlates with stellar surface density, gas surface density, molecular-to-atomic gas ratio, and dynamical equilibrium pressure. In EMPIRE, the star formation rate per unit dense gas is anticorrelated with these same environmental parameters. Thus, although dense gas appears abundant in the central regions of many spiral galaxies, this gas appears relatively inefficient at forming stars. These results qualitatively agree with previous work on nearby galaxies and the Milky Way’s Central Molecular Zone. To first order, EMPIRE demonstrates that the conditions in a galaxy disk set the gas density distribution and that the dense gas traced by HCN shows an environment-dependent relation to star formation. However, our results also show significant (±0.2 dex) galaxy-to-galaxy variations. We suggest that gas structure below the scale of our observations and dynamical effects likely also play an important role.

Developing predictive methods to forecast the impacts of existing and emerging invasive species is of critical importance to biodiversity conservation. However, invader impacts are context-dependent, making reliable and robust predictions challenging. In particular, it is unclear how temporal variabilities in relation to temperature regime shifts influence invader ecological impacts. In the present study, we quantify the functional responses of three coexisting freshwater fishes: the native freshwater River Goby Glossogobiuscallidus, and the non-native Mozambique Tilapia Oreochromismossambicus and Western Mosquitofish Gambusiaaffinis, under two temperature treatments using chironomid larvae as prey. This was used along with fish abundance data to determine temporal differences in ecological impacts of each fish species between seasons (i.e. at two corresponding temperatures). All three fish species exhibited potentially population-destabilizing Type II functional responses. Their maximum feeding rates were consistently higher in the warm temperature treatment, whereas attack rates tended to be reduced. Non-native Mozambique Tilapia had the highest maximum feeding rate under both temperature treatments (18 °C and 25 °C), followed by the non-native Western Mosquitofish and lastly the native River Goby, suggesting greater per capita impacts on native prey by non-native fishes. The predatory fish abundances differed significantly according to season, with native River Goby and non-native Mozambique Tilapia generally more abundant than non-native Western Mosquitofish. By multiplying functional response maximum feeding rates with abundances of each fish species across the seasonal gradient, the relative impact potential of non-native Mozambique Tilapia was consistently higher compared to that of native gobies. Western Mosquitofish impacts were less apparent, owing to their low abundances. We demonstrate how seasonal temperature fluctuations affect the relative impact capacities of introduced species and the utility of consumer functional response and the relative impact potential metric in impact forecasting.

Renegotiation‐proof mechanism design with imperfect type verification
Authors: Silva Francisco
Published: August 2019

I consider the interaction between an agent and a principal who is unable to commit not to renegotiate. The agent's type affects only the principal's utility. The principal has access to a public signal, correlated with the agent's type, that can be used to (imperfectly) verify the agent's report. I define renegotiation‐proof mechanisms and characterize the optimal one. The main finding of this paper is that the optimal renegotiation‐proof mechanism induces pooling at the top, i.e., types above a certain threshold report to be the largest type, while types below the threshold report truthfully.

Authors: Suryaman Suryaman , Mulyono Herri
Published: August 2019

In this paper, we present a digital application developed to prevent teachers’ absenteeism in a private university in Indonesia. In particular, we evaluated the development and the application of an Android-based attendance management system (AAMS) to monitor teachers’ attendance and their teaching activity at a private university in the capital city of Jakarta, Indonesia. Adopting a design-based research approach, we observed the development procedure and interviewed three end-users of the application, i.e. teachers. The findings of the study revealed the potential use of AAMS as a digital tool to prevent absenteeism among university teachers. The three main challenges were highlighted during the application of AAMS, including the processing time duration and system error, the reporting and analytics issues, and the input manipulation. Furthermore, a recommendation is offered on the basis of the findings.

Authors: Xue Xiao Wei , Wang Chun Xu , Li Yong , Han Shun , Liu Shao Zun , Yuan Wu Hua
Published: August 2019

Hot deformation behavior of as-cast 300M steel was investigated in the temperature range of 850-1200°C and strain rate range of 0.01-10 s-1 using Gleeble-3800 thermo-mechanical simulator. Based on the true stress-strain curves corrected for friction, flow stress behavior and deformation mechanism were analyzed, and the constitutive model of as-cast 300M steel was established based on the Arrhenius model and Zener-Hollomon parameter (Z). The microstructure after deformation was observed by Olympus GX51 microscope. The experimental results show that the flow stress of as-cast 300M steel decrease with the increase of deformation temperature and the decline of strain rate. The dynamic recrystallization is more likely to occur at higher temperatures and lower strain rates. By regression analysis, the hot deformation activation energy (Q) of the as-cast 300M steel was calculated to be 360.332 kJ/mol. Microstructure evolution is greatly affected by deformation temperature and strain rate. The dynamic recrystallized grain size increases with the enhancement of deformation temperature and the decrease of strain rate.
Genomics meets immunity in pancreatic cancer: Current research and future directions for pancreatic adenocarcinoma immunotherapy
Authors: Bowers Jacob S. , Bailey Stefanie R. , Rubinstein Mark P. , Paulos Chrystal M. , Camp E. Ramsay
Published: August 2019

Pancreatic adenocarcinoma (PDAC) remains a formidable disease that needs improved therapeutic strategies. Even though immunotherapy has revolutionized treatment for various solid tumor types, it remains largely ineffective in treating individuals with PDAC. This review describes how the application of genome-wide analysis is revitalizing the field of PDAC immunotherapy. Major themes include new insights into the body’s immune response to the cancer, and key immunosuppressive elements that blunt that antitumor immunity. In particular, new evidence indicates that T cell-based antitumor immunity against PDAC is more common, and more easily generated, than previously thought. However, equally common are an array of cellular and molecular defenses employed by the tumor against those T cells. These discoveries have changed how current immunotherapies are deployed and have directed development of novel strategies to better treat this disease. Thus, the impact of genomic analysis has been two-fold: both in demonstrating the heterogeneity of immune targets and defenses in this disease, as well as providing a powerful tool for designing and identifying personalized therapies that exploit each tumor’s unique phenotype. Such personalized treatment combinations may be the key to developing successful immunotherapies for pancreatic adenocarcinoma.

Published: August 2019

The study developed a screening schedule for teachers to describe the abilities of children with severe disabilities. teachers were trained in the use of such an assessment procedure. Both the schedule as well as the training were evaluated. Results indicated that the schedule can be regarded as adequate for future use as teachers found it easy to use and applicable to their situation. Scoring the schedule requires more practice and training as this is a more advanced skill. Specific issues had an effect on the results, e.g, the teachers' familiarity with the type of disability observed, their qualifications and experience.
Interaction between a teacher and the non-speaking as well as speaking children in the classroom
Authors: Popich Elsa , Alant Erna
Published: August 2019

This study examined the verbal interactions which occurred between a teacher and two groups of children (children who were non-speaking as well as children who were speaking). Descriptive data, generated by analysing ten lessons, suggested that the teacher's interaction with the children who were non-speaking differed, in terms of quantity and quality. She directed approximately 10% less interaction at each of the three non-speaking children, when compared with the number of interactions that she directed at each of the five speaking children. However, she did not spend an equal amount of time interacting with each of the non-speaking children. Her interaction with the non-speaking children was dominated by questions, attention directing and requesting. Verbalization types, such as answering and imitating did not occur at all in the teacher's interaction with the non-speaking children. This implies that the non-speaking children's learning experiences in the classroom differed from the speaking children's learning experiences. Possible reasons for these discrepancies were proposed, namely that the teacher's attitudes, skill and knowledge played a role, but the non-speaking children's lack of access to communication was also considered to be a factor in determining the amount and type of interaction.

In hierdie studie is die invloed van veroudering op die spraakdiskriminasievermoe van bejaarde gehoorapparaatgebruikers ondersoek. 'n Opname-metode is gebruik en dertig proefpersone, met dieselfde graad van perifere gehoorafname, is in twee groepe van vyftien persone elk verdeel. Groep 1 het bestaan uit bejaarde gehoorapparaatgebruikers wat geen of geringe spraakdiskriminasieprobleme ervaar, terwyl Groep 2 ernstige spraakdiskriminasieprobleme ervaar. 'n Verskeidenheid toetse, naamlik die Sintetiese Sinsidentifikasietoets, die Verspringende Spondeewoordtoets en die aanbieding van monosillabiese woorde tesame met 'n ipsi-kompeterende spraakboodskap, is gebruik om hul spraakdiskriminasievermoe in verskillende luistersituasies te bepaal. 'n Selfevaluasieskaal is ook deur die bejaardes voltooi.Die resultate van hierdie studie toon dat die verouderingsproses en die effek hiervan op veral sentrale ouditiewe prosessering, bydra tot die kompleksiteit en uiteenlopendheid van bejaarde gehoorapparaatgebruikers se spraakdiskriminasieprobleme. Die resultate beklemtoon verder die noodsaaklikheid van volledige intervensieprogramme vir bejaarde gehoorapparaatgebruikers.
Clinical training of undergraduate communication pathology students in the neonatal assessment and neonate-caregiver interaction in South Africa

Developing an undergraduate clinical training module in Early Communication Intervention (ECI) that provides sufficient opportunity for students' learning experiences, and that allows contextually relevant and ethically accountable services to clients, as well as the dissemination of the latest scientific findings to both students and clients, poses a significant challenge. The article describes the development of a clinical training block and the development of an appropriate instrument for the assessment of neonatal communication skills that was used in this student practical. A qualitative research approach, employing a series of formative assessments, was used to refine the instrument. The results indicated changes in the content and use of the neonatal assessment instrument regarding the approach to infant and caregiver risk assessment; caregiver beliefs about neonatal capabilities; newborn state observation; caregiver training; language, cultural and age barriers; collaboration with nurses; kangaroo mother care; involvement of caregivers during the assessment; and adolescent mothers. The results confirmed the need for the ongoing refinement of an instrument to ensure quality training of students in the difficult field of neonatal assessments and neonate-caregiver interaction. The results also highlighted to the importance of initiating ECI services before birth in communities at risk for infant neglect and abuse, and the close relationship between ECI service delivery and student training.
Measuring entrepreneurial attitudes inter-culturally: Is it possible?
Authors: Boshoff A. B. , Hoole C.
Published: August 2019

Non-portability of constructs is seen as a potential problem in international research. Studying attitudes as an approach to understanding entrepreneurs is seen as potentially profitable in order to understand members of this entrepreneurs. The construct validity of the Entrepreneurial Attitude Orientation Scale (as adapted) when used on a South African sample is psychometrically examined by means of Exploratory and Confirmatory Factor Analysis. It is found that the factor structure differs from that established on a North American sample. Portability of constructs embodied in measuring instruments seems to be a significant problem when research is contemplated on an international scale.
An economic case for regulating against the use of non-deposit carrying glass containers of beverage in South Africa
Authors: Hosking S.
Published: August 2019

As a result of minimal private cost many people dispose of non-deposit bearing glass containers in ways which cause glass pollution: hazardous broken bottles and litter. This pollution imposes costs on users of the affected environment and on municipalities, which have most of the responsibility to clean up, although in South Africa the two main glass packaging producers also play a role by operating a recycling system. A case study was carried out in the Port Elizabeth area in which exploration is made of the glass that does not get recycled and an intuitive analysis is made of the costs of different options for managing recyclable glass waste. It is concluded that the case deserves further investigation for introducing legislation in South Africa making bottle deposits mandatory.
Dès les Relations avec les Parents à la Relation Conjugale: La Continuité et la Discontinuité des Modèles d’Attachement
Authors: Guedes Dilcio Dantas , Moreira Patricia Carvalho
Published: August 2019

Le but de cette étude a été de vérifier la relation entre les représentations d’attachement vis-à-vis des parents et aux partenaires lors des situations de stress relationnel. Un entretien semi-structuré focalisé sur les représentations d’attachement a repéré les représentations d’attachement des figures d’attachement de soixante adultes. Les résultats ont indiqué une certaine similitude entre les représentations d’attachement par rapport aux parents et les représentations d’attachement associées aux partenaires des individus qui ont vécu des situations de stress relationnel. Cette similitude a été plus systématique vis-à-vis de la mère et au premier partenaire amoureux. Il semble que, lorsque l’insécurité d’attachement par rapport aux parents et partenaires prévaut, les représentations d’attachement des relations vécues avec les parents peuvent être éveillées à l’occasion de stress relationnel.
O Manicômio no Cariri Cearense: Análise Arquegenealógica de sua Abertura e Fechamento
Authors: Gimbo Leda Mendes , Dimenstein Magda Diniz Bezerra , Leite Jáder Ferreira
Published: August 2019

Este artigo objetiva analisar as formações discursivas e não discursivas que possibilitaram a abertura de um hospital psiquiátrico na Região do Cariri cearense, entre os anos 1970 e 2016. Propõe o uso dos conceitos foucaultianos de arqueologia e genealogia enquanto método e estratégia de análise. A hipótese de pesquisa defendida é de que a abertura desse hospital faz parte de um processo amplo de instalação de hospitais psiquiátricos no Brasil e aponta para o internamento enquanto lógica massiva de intervenção em Saúde Mental no Brasil, que, embora segregacionista e excludente, se manteve até o final da década de 1980.
Análise Fenômeno-estrutural da Temporalidade no Primeiro ano de Vida
Authors: Ceron-Litvoc Daniela , Messas Guilherme Peres
Published: August 2019

Este artigo apresenta uma proposta fenomenológica estrutural de psicologia do desenvolvimento dos primeiros 12 meses de vida. A literatura clássica fenomenológica fomenta, nesse artigo, um aprofundamento da compreensão antropológica piagetiana do desenvolvimento. As descrições minuciosas de Jean Piaget do desenvolvimento de seus três filhos foram utilizadas como paradigma para a apresentação de uma proposta de como a temporalidade se apresenta nos 12 primeiros meses de vida. Ao constatarmos uma temporalidade em expansão, porém imatura, aprofundamos a compreensão do papel vital do contato interpessoal no primeiro ano de vida como fator constituinte de uma estrutura psíquica saudável.

Abstract. Balloons are used for various in situ measurements in the atmosphere. On turbulence measurements from rising balloons there is a potential for misinterpreting wake-created fluctuations in the trail of the balloon for atmospheric turbulence. These wake effects have an influence on temperature and humidity measurements from radiosondes as well. The primary aim of this study is to assess the likelihood for wake encounter on the payload below a rising balloon. Therefore, we present a tool for calculating this probability based on radiosonde wind data. This includes a retrieval of vertical winds from the radiosonde and an uncertainty analysis of the wake assessment. Our wake evaluation tool may be used for any balloon–gondola distance and provides a significant refinement compared to existing assessments. We have analysed wake effects for various balloon–gondola distances applying atmospheric background conditions from a set of 30 radiosondes. For a standard radiosonde we find an average probability for wake encounter of 28 %, pointing out the importance of estimating wake effects on sounding balloons. Furthermore, we find that even millimetre-sized objects in the payload can have significant effects on high-resolution turbulence measurements, if they are located upstream of the turbulence sensor.
