Multimodal Summarization with Guidance of Multimodal Reference
Authors: Zhu Junnan , Zhou Yu , Zhang Jiajun , Li Haoran , Zong Chengqing , Li Changliang
Published: June 2020

Multimodal summarization with multimodal output (MSMO) is to generate a multimodal summary for a multimodal news report, which has been proven to effectively improve users' satisfaction. The existing MSMO methods are trained by the target of text modality, leading to the modality-bias problem that ignores the quality of model-selected image during training. To alleviate this problem, we propose a multimodal objective function with the guidance of multimodal reference to use the loss from the summary generation and the image selection. Due to the lack of multimodal reference data, we present two strategies, i.e., ROUGE-ranking and Order-ranking, to construct the multimodal reference by extending the text reference. Meanwhile, to better evaluate multimodal outputs, we propose a novel evaluation metric based on joint multimodal representation, projecting the model output and multimodal reference into a joint semantic space during evaluation. Experimental results have shown that our proposed model achieves the new state-of-the-art on both automatic and manual evaluation metrics. Besides, our proposed evaluation method can effectively improve the correlation with human judgments.

Published: June 2020

The microstructure and performances of GH4169 nickel (Ni)-based alloy were studied after adding the elements rhenium (Re) and tungsten (W) and then conducting heat treatment. The alloy containing the element rhenium showed less δ phase after heat treatment. For both alloys containing the element tungsten and the GH4169 alloy without any element, the δ phase and rectangular carbide were all precipitated after the heat treatment. The creep rupture life of the alloy added with the element rhenium was higher than that of the alloy added with the element tungsten at a high temperature. When a mixture of 75% sodium sulfate (Na2SO4) and 25% sodium chloride (NaCl) was applied at 950°C under the same conditions, the thermal corrosion resistance of the nickel-based alloy containing rhenium was obviously better than that of the nickel-based alloy containing tungsten. The hot-corrosion resistance of the GH4169 alloy without adding any element was slightly better than that of the alloy with tungsten.
Failure analysis of historic vertical breakwaters, part 1: Wick
Authors: Allsop Nigel William Henry , Bruce Tom
Published: June 2020

Many historic breakwaters failed early in their life, leaving little information by which to analyse or understand their failures. As part of a wider analysis of ‘old breakwaters’, the first author has analysed the ‘stability’ of example breakwaters using analytical methods developed over the past 20 years with co-researchers. This analysis is illustrated by three case studies, the first covered in this paper and the second two in the companion paper: Wick (designed by Thomas Stevenson, failed 1870–1877)—Alderney (damaged even during construction, lost its outer length 1865–1889)—and Dover (still shows high stability after 110 years). In these case studies, representative cross-sections have been derived from historical records, as have the approach bathymetry. Representative wave conditions are transformed to the breakwater toes, including depth-limiting and impulsive breaking effects. Empirical formulae developed during and since the PROVERBS (Probabilistic Design Tools for Vertical Breakwaters) project have been used to explore the incidence of wave impact loads, the main momentum loads and the impulsive loads. Factors of safety against sliding and/or overturning have been determined for each example over a range of representative wave conditions and compared with reality.
The role of particle shape on hydraulic conductivity of granular soils captured through Kozeny–Carman approach
Authors: Nguyen T. T. , Indraratna B.
Published: June 2020

Previous studies indicate that particle shape plays an important role in the hydraulic conductivity (k) of granular materials, often represented through the Kozeny–Carman (KC) concept. Several recent studies have improved the accuracy of the KC approach using the particle-size distribution (PSD) to estimate the specific surface area of particles but overly simplifying the effect of particle shape. This current study innovatively adopts the micro-computed tomography technique to compute particle shape parameters of different granular materials (e.g. glass beads, sand and crushed gravel) and then incorporate these parameters into the KC equation to estimate k more accurately, which is then validated with experimental data. The results indicate that k varies significantly according to different particle shapes even if the same mean porosity and PSD are retained. Particles that are less spherical and rounded have a larger fluid–particle contact area (i.e. larger shape factor), hence a smaller hydraulic conductivity. The study suggests a shape factor of 1·28–1·52 for natural sand and 1·84–2·1 for crushed sand and gravel can be used for KC method to estimate k while a porosity-dependent equation is proposed to estimate the tortuosity for different shaped materials.

Published: June 2020

Juice blending is one of the methods that can improve the nutritional quality of juices. The aim of this study was to evaluate the quality of juice product produced from blends of watermelon fruit pulp juice and baobab fruit pulp powder. This study was also aimed at promoting the use
of underutilized African baobab and leverage on the benefits that can be derived from blending these two wonderful plant resources. Four blend
ratios and codes of 100:0 (W100), 80:20 (W80B20), 60:40 (W60B40) and 50:50 (W50B50)
were developed for watermelon fruit pulp juice and baobab fruit pulp powder, respectively. The physicochemical attributes, mineral composition, microbiological and sensory attributes of the samples were analyzed using standard methods. The increase in baobab fruit pulp powder concentration in watermelon fruit pulp juice increased the titratable acidity (0.24 to 0.48 %), total sugar content (6.0 to7.85 oBrix),
total solid (1.30 to 1.37 %), viscosity (473.67 to 730.30 cP), Vitamin C
(126.25 to 236.70 mg/100 mL), Vitamin A (18.67 to 80.33 mg/100 mL), calcium (1.97 to 3.46 %), potassium (1.09 to 2.07 %) and iron (3.10 to 4.43 ppm) contents, while decreasing the pH (5.19 to 4.08), total viable
count (4.0×104 to 2.0×102 cfu/mL), yeast and mould count (3.2×104 to 0.0×100
cfu/mL) as well as sensory attributes whose values ranged from 3.80 to 7.60 on a 9-point hedonic scale. Therefore, blending watermelon fruit pulp juice and baobab fruit pulp powder has the ability to enhance the physicochemical , micronutrient content, microbiological and sensory characteristics of the samples.

Objectives: The aim of the present study was to compare the perception of caregivers regarding the oral health status of children and adolescents with cerebral palsy (CP) and those with typical development. Study Design: Study group (SG) was composed of 35 children and adolescents with a clinical diagnosis of CP and their caregivers. Control group (CG) was composed of 35 individuals with typical development (matched with the SG for age, sex and caries activity) and their caregivers. Questionnaire was administered to caregivers addressing the oral health of individuals under their care. Caries activity, dmft/DMFT index, visible plaque index (VPI) and occlusal characteristics were determined. Results: Statistically significant differences were found in the perceptions of dental problems (p = 0.004) and gingival bleeding (p = 0.013). Individuals in SG whose caregivers perceived dental problems had a higher mean VPI (50.84 ± 5.11%) than those in CG (27.97 ± 6.50%). The mean dmft/DMFT in the SG was 2.77 ± 3.20. Class II molar relationship, overjet and anterior open bite were more prevalent in the SG. Conclusion: Caregivers of children/adolescents with CP perceive more oral problems, such as visible plaque, gingival bleeding and malocclusion, than caregivers of children/ adolescents with typical development.

Published: June 2020

Os processos tradicionais de purificação do biodiesel são onerosos e lentos, gerando grandes volumes de efluentes para atender os parâmetros de qualidade exigidos pela legislação. Este trabalho avalia os efeitos de novas combinações para a síntese de líquidos iônicos (LI’s) sobre a eficiência do solvente na remoção de impurezas do biodiesel de soja. Os LI’s análogos a base de cloreto de colina, sintetizados com a mistura eutética de glicerol, etilenoglicol e trietilenoglicol, foram usados para lavar o biodiesel pré-purificado em diferentes razões. O LI L9 composto por cloreto de colina, glicerol e trietilenoglicol (1:2:1), teve a maior eficiência (98,05%) quando usado na razão R2 (1:1), com um tempo ótimo de lavagem de 60 minutos. O biodiesel bruto também foi purificado com o novo solvente e apresentou uma boa eficiência mesmo quando reutilizado, em conformidade com a RANP 45/2014.
O direito à integração do trabalho e o sindicalismo no Mercosul

Published: June 2020

A busca por expansão e desenvolvimento da economia fez com que os países se aglutinassem em Blocos Regionais para ter maior poder de barganha no desenrolar das atividades comerciais. O cenário da regionalidade, marcado pela livre circulação de bens, mercadorias e capitais, originariamente se mostra relutante a assumir uma face que também se traduza em bem-estar social para as populações diretamente envolvidas, o que ameaça pontualmente o futuro da proteção das relações de trabalho. A partir daí, a pesquisa se utiliza do método dedutivo para perpassar os desafios do sindicalismo no Mercosul a fim de concluir que o movimento tem apresentado importantes propostas para enfrentar a relação capital-trabalho na atual conjuntura econômica, trazendo significativas contribuições para o direito à integração do trabalho no âmbito do Bloco Econômico formado pelos países do Cone Sul. O estudo se mostra relevante porque o fortalecimento da atuação sindical no Mercosul possibilita a internacionalização da disputa entre a apropriação dos meios de produção e a justa distribuição da riqueza socialmente produzida.
Direito à saúde no Brasil: parâmetros normativos para densificação de um conteúdo mínimo
Authors: Almeida Luiz Antônio Freitas de
Published: June 2020

A judicialização do direito à saúde é um fenômeno crescente no Brasil. Os casos difíceis versam sobre medicamentos e tratamentos não incluídos nas políticas do sistema único de saúde – SUS, tema que foi enfrentado pelo Supremo Tribunal Federal no Recurso Extraordinário n. 566.471/RN. A resposta judicial ineludivelmente perpassará por uma ponderação, que deve passar pela estrutura analítica da norma da proporcionalidade e seus testes. Contudo, para uma maior racionalidade jurídica advinda da maior objetivação da ponderação, é importante acrescentar o conteúdo mínimo como padrão que define o grau de deferência e o ônus de argumentação do Estado. Nessa linha de pensamento, com o uso do método técnico-jurídico, o artigo oferece os parâmetros normativos para auxiliar na definição do conteúdo mínimo do direito à saúde no Brasil. Antes, porém, será preciso verificar a compreensão de conteúdo mínimo dada pelo Comitê de Direitos Econômicos, Sociais e Culturais da Organização das Nações Unidas.
O direito a um emprego na zona do euro. Uma proposta de estabilização
Authors: Arjona-Sánchez Miguel José
Published: June 2020

A batalha pelo desenvolvimento efetivo do direito ao trabalho representa a necessidade de realização de políticas econômicas para alcançar o pleno emprego. Após as exitosas experiências dos new dealers e do keynesianismo, a Curva de Philips erigiu a necessidade de manter uma taxa de desemprego natural que garantisse o controle da inflação. É uma questão que paulatinamente passou a ser prevista nos tratados da União Europeia. No entanto, a reconsideração monetária inaugurada após o Nixon shock possibilitou uma relação distinta entre ambos os parâmetros, conforme havia sido definida pelos teóricos do “trabalho garantido”, transformando o pleno emprego em uma ferramenta de controle inflacionário, que interessa especialmente para a Eurozona, devido aos seus déficits estruturais.
Indiscipline in South African Schools: the Parental / Community Perspective
Authors: Wolhuter Charl C. , van der Walt Johannes L.
Published: June 2020

South Africa is struggling with the problem of indiscipline in schools. The issue of indiscipline in South African schools has been subjected to research for almost two decades. This research has revealed that learner (in)discipline in a school is related to six sets of factors, namely learner-related factors, teacher-related factors, school-related factors, education system-related factors, parent-related factors, and society-related factors. All of these factors have now been researched in respect to the situation in South Africa, with the exception of the parent / community factor. The aim of this article is to report on research that was done regarding this outstanding factor with regard to learner (in)discipline in South African schools. The constructivist-interpretivist approach was employed, in order to recast information gleaned from available international literature into a theoretical framework. The South African context was then analysed by using the theoretical framework. It was found that within the parental-community factor in determining the state of learner-discipline in schools four sub-factors can be distinguished, namely parental style, parental model for example, family stress and parent-school relations. These have definite life-philosophical underpinnings, which are also outlined in analysing and interpreting the South African situation.

Published: June 2020

The article discusses the gender aspects of health, proceeding from the assumption that taking them into account is likely to increase the effectiveness of motivational measures in the field of forming healthy lifestyles. The methodological basis of this paper is the concept of health promotion supported by WHO that is based on intersectoral and interdisciplinary approaches. It incorporates both a certain system of values, primarily active involvement of people in maintaining their health, and a set of state activities, among which motivating people to healthy lifestyles is important. Behavioral economics as an area of an interdisciplinary research on decision-making substantiates the mechanisms that should be used, among other things, to achieve the goals of healthcare policy, and to solve such problems of modern society as lack of physical activity, tobacco and alcohol abuse, and unhealthy diet.Gender approach that includes gender aspects in the process of analyzing the situation and making political decisions aimed at improving population health becomes a precondition for increasing the effectiveness of motivational measures taken in the interests of promoting the health of citizens. The results of the surveys on the impact of behavioral factors on the health status of the population of Russia conducted by the Russian statistical agency (Rosstat) in 2013 and 2018 were used as a source of empirical data. They made it possible to identify both the differences and the similarities of women and men with regard to behavior motives concerning certain parameters of a healthy lifestyle, namely physical activities and diet. The authors conclude that, despite the importance of using measures aimed at changing behavior, sustainable overcoming of gender stereotypes depends on the intersection of behavioral and socio-economic determinants of health and healthy behavior.

The article presents the results of a study of employment in the Russian media. Given the global trend of feminization of the media, the issues of professional self-realization, salary and career growth were analyzed through the prism of gender. The research tools included, firstly, a mass questionnaire of media workers holding both creative and administrative positions; secondly, a series of in-depth structured interviews with experts experienced in working as journalists and editors-in-chief; heads of journalistic associations; owners and founders of publications; heads of HR services of media structures; and thirdly, analysis of statistics relating to the editorial corps of editions at the municipal, regional and national levels — in the latter case the data on leading news agencies and Internet resources were analyzed. The study confirmed the trend of feminization, which is based on the socio-political (reducing the influence of the media and, consequently, lower salaries) and technological aspects (spread of information technology, forcing traditional media to compete with social media, saving on staff and reducing the quality of materials). Dissatisfied with the decline in income and in the prestige of the profession men were replaced by women, that was facilitated by a marked increase in the accessibility of journalistic education. The size of salaries depends on decisiveness of the media, on region, and also on the topics that a journalist is engaged in; in general, the willingness of women to work for a lower salary is forced. Precarious employment that is widespread in the industry deprives workers of social protection, while most of them are young women. The article examines the so-called “glass ceilings”: the more influential the media, the less often it is led by a woman. At the same time, only a quarter of the respondents acknowledge the presence of gender discrimination in their industry, and most of them are women. This is partly due to the prevalence among journalists of both sexes of traditional ideas about the distribution of the social roles of men and women in family and in society.
Gender stereotypes in digital society: modern tendencies
Authors: Khasbulatova Olga A. , Smirnova Inna N.
Published: June 2020

The relevance of this article is determined by the sustainable reproduction of gender stereotypes in various areas of Russian society. It is shown that gender stereotypes act as part of a person’s motivational complex and, under certain conditions, become a barrier to its development. The purpose of the study is to determine the nature, functions and mechanisms of the impact of gender stereotypes on the life strategies of an individual in a digital society. Offering a typology of personal life strategies, the authors consider a system for transmitting gender stereotypes in preschool and school education. They consider two types of life strategies: the development strategy and the strategy of everyday life. The development strategy refers to the behavior of individuals, which corresponds to the rejection of dependent moods, focus on continuing education and professional success, creative use of their personal potential. The strategy of everyday life involves a focus on solving not long-term, but life’s immediate problems, as well as a high degree of dependence of an individual on the social support of the state. Using the example of content analysis of preschool children’s literature, as well as textbooks of primary, secondary and high school, the authors show that the set of professions and family roles represented in the studied content forms and broadcasts gender stereotypes about professions, occupations, and social roles. High degree of the influence of gender stereotypes on the choice of a profession is a barrier to the development of personality and has a negative impact on the quality of women’s human capital. The state and society may face the problem of a significant part of women abandoning the development strategy in favor of the daily life strategy. The results of the study can be used in the work of Federal and local authorities, in implementation of the Federal projects «Digital Economy» and «Education», as well as in scientific works on this issue.
Wybrane problemy metodologiczne dotyczące badań bezpieczeństwa
Authors: Sztumski Janusz
Published: June 2020

Podejmując rozważania nad bezpieczeństwem, trzeba na wstępie możliwie dokładnie określić znaczenie tego słowa oraz dokonać jego konkretyzacji. Albowiem słowo „bezpieczeństwo” używane bez określenia jego znaczenia jest tylko pojęciowym tworem, który nie ma desygnatu istniejącego w materialnym świecie. A do konkretyzacji tego słowa konieczne jest wskazanie, kogo lub czego ma ono dotyczyć.

Bezpieczeństwo dowolnego obiektu — w szerokim tego słowa znaczeniu, czyli podmiotowym lub przedmiotowym będące przedmiotem badań — wynika z takiego jego aktualnego stanu istnie-jącego w danym miejscu i czasie, w  którym nie dostrzegamy żadnych dla niego zagrożeń.

Jest to oczywiście stan idealny, ponieważ nigdy nie możemy być pewni, czy wszystkie zagrożenia spośród istniejących zostały przez nas dostrzeżone oraz czy nie pojawiły się nowe.

W artykule tym wskazuję także na to, że możliwości postrzegania zagrożeń są uwarunkowane podmiotowo, przedmiotowo i sytuacyjnie.
Metodologiczna tożsamość antropologii bezpieczeństwa. Prolegomena
Authors: Piwowarski Juliusz , Trzciński Łukasz
Published: June 2020

Całkowite bezpieczeństwo człowieka jest wyjątkowym stanem, ponieważ w dalszym ciągu dzie-limy z innymi gatunkami podstawowe cechy ukształtowane w ciągu historii naturalnej. Wyjątkowość ludzkości wynika jednak z tworzenia przez nią szeroko rozumianej kultury. Powstający nurt antro-pologii bezpieczeństwa, ma związki z badaniami nad kulturą przez antropologię fizyczną, filozo-ficzną czy religijną, ale głównie jest on związany z antropologią społeczno-kulturową, co implikuje potrzebę włączenia w nią elementów kulturoznawczych. Odnosząc się z kolei do filozoficznych pod-staw kwestii dotyczących bezpieczeństwa, antropolog bezpieczeństwa powinien koncentrować się na antropologicznych i kulturoznawczych aspektach dążeń ukierunkowanych na uzyskiwanie stanu wolności od zagrożeń. Tym samym obszarem badań dla antroposekuritologicznego nurtu nauki, który może być interpretowany jako subdyscyplina nauk o bezpieczeństwie, jest de facto całe spek-trum elementów kultury bezpieczeństwa. Kultura bezpieczeństwa stanowi zjawisko występujące w całym obszarze ogromnego dorobku kultury ludzkiej, towarzyszące rozwojowi człowieka od za-rania jego dziejów bez względu na to, czy w danym kontekście kulturowo-czasowo-przestrzennym ma tego świadomość, czy też kreuje to zjawisko i jego funkcjonowanie w sposób intencjonalny.

Authors: Gorzko Marek
Published: June 2020

Artykuł zawiera rozważania dotyczące teoretycznego znaczenia kategorii bezpieczeństwa i po-czucia bezpieczeństwa na gruncie socjologii. Pojęcia te są wykorzystywane w teoriach dotyczących różnych poziomów organizacji rzeczywistości społecznej. Krótko zostały omówione przykłady ta-kich zastosowań: a) w  implikacjach koncepcji „społeczeństwa ryzyka” U. Becka; b) jako katego-ria łącząca działania jednostkowe i własności systemu społecznego w koncepcji M. Marody oraz c) jako pojęcia przydatne do charakterystyki pewnych aspektów porządku interakcyjnego w ujęciu E. Goffmana.
Możliwość aplikacji modelu homo agens-institutionalist w badaniach Policji
Authors: Kołodziej Tomasz
Published: June 2020

Artykuł koncentruje się na możliwościach zastosowania, osadzonego w neoinstytucjonalnej perspektywie, modelu homo agens-institutionalist w badaniach Policji i policjantów. Tekst prezentuje założenia modelu zaproponowanego przez Piotra Chmielewskiego. Model ten pozwala analizować decyzje i działania funkcjonariuszy Policji jako członków organizacji działających w określonym porządku instytucjonalnym. Uwzględnia ograniczenia, które uniemożliwiają funkcjonariuszowi podejmowanie decyzji i działań w sposób całkowicie racjonalny, który charakteryzuje model homo oeconomicus. Wskazuje on ograniczenia wynikające z subiektywnego postrzegania rzeczywistości, ograniczonej wiedzy i ograniczonej zdolności przetwarzania informacji pochodzących z zewnątrz, emocji odczuwanych przez każdą osobę i jej oportunizmu. Ponadto zakłada, że każda jednostka działa umyślnie i dąży do racjonalności. Jednocześnie uwzględniony jest fakt, że każdy człowiek działa w wielu organizacjach i instytucjach. Zastosowanie prezentowanego modelu pozwala na wie-lowymiarową analizę na wszystkich poziomach — makro-, mezo- i mikrospołecznym. Umożliwia również włączenie do analiz instytucji, organizacji i poszczególnych podmiotów.
