Culture, Motivational Attributes and Employees’ Perception towards CSR Practices: Evidence From Pakistan
Authors: Jabeen Sultana , Siddiqui Danish Ahmed
Published: December 2019

The purpose of this paper is to analyze the employees–corporate social responsibility (CSR) relationship by studying the influence of two cultural values – collectivism and masculinity –on the formation of CSR perceptions. We adopted theoretical framework proposed by Hur and Kim (2017), in which Hofstede’s cultural framework was proposed to explain the effect of the cultural values on employees’ perceptions of CSR practices with the mediatory role of motivational attributions. To establish this framework empirically on Pakistan, a survey questionnaire was used to collect data from 190 employees’ in Pakistan. Data analysis was performed using SEM and CFA. The results indicate that collectivistic (masculine) values were positively (negatively) related to perceptions of CSR. Furthermore, intrinsic attributions of CSR initiatives mediate the positive relationship between collectivism and CSR perceptions and the negative relationship between masculinity and CSR perceptions. These findings suggest that managers must seek to understand employees’ cultural characteristics and the attributions of CSR motivations in order to engage them in driving CSR practices effectively and displaying a positive image of organization.

Authors: Magalhães Costa Eliana Auxiliadora , Moreira Lícia Lígia , Gusmão Maria Enoy Neves
Published: December 2019

Objetivos: Descrever a incidência de infecção do sítio cirúrgico (ISC) em seguimento após alta em hospital dia (HD) e comparar esses indicadores com dados de hospitais convencionais. Método: Estudo de coorte histórica composto de 74.213 pacientes operados e monitorados num HD de Salvador (BA), entre 2012 e 2017. Resultados: No período estudado, o sistema de vigilância do HD monitorou 85,1% dos pacientes após a alta e foi identificada incidência total de ISC de 0,3%, com variação de 0,2 a 0,4% entre os anos, taxas estatisticamente menores do que as reportadas para ISC em regime de internação hospitalar. Conclusão: Os indicadores de ISC revelados neste estudo ratificam que a modalidade da assistência cirúrgica ambulatorial porta menor risco de aquisição de infecção para os pacientes operados, quando comparados com os dados de infecção cirúrgica de pacientes em hospitais convencionais. Entretanto, torna-se indispensável um sistema de seguimento dos pacientes após a alta, no sentido de evitar a subnotificação e os sub-registros dos dados de ISC, pois na ausência de ambos se podem ocultar riscos e identificar taxas irreais

Published: December 2019

The oral hygiene of individuals with Parkinson disease (PD) is markedly impaired by difficulties in toothbrushing due to motor impairment and tremors. Additionally, it appears that other features associated with PD have an impact on the quality of oral health. Objective: this cross-sectional observational study characterized the oral health condition of individuals with PD. Methods: fifty individuals with PD, aged 53 to 94 years, users of medication for such condition were examined. The research participants had their oral cavities examined to assess prosthetic use and need; index of Decayed, Missing and Filled Teeth (DMFT); Community Periodontal Index (CPI); Periodontal Attachment Loss (PAL); and oral mucosa. In addition, a questionnaire was applied to obtain personal data, general health, and oral health. The data were analyzed using descriptive statistics. Results: a high prosthetic use was observed in the upper arch (92%), while the lower arch revealed high prosthetic need (66%). The DMFT index showed a high number of missing teeth, CPI showed a prevalence of 43% of dental calculus, and PAL revealed 28% of attachment loss of 4-5 mm. The most frequent findings in the assessment of oral mucosa were denture stomatitis and inflammatory fibrous hyperplasia. Conclusion: PD patients refer xerostomia and present high number of missing teeth, a minority of healthy teeth, and oral lesions, representing a target population for specialized oral health care.

Published: December 2019

Objetivo: identificar o conhecimento de pais/responsáveis sobre como proceder em caso de traumatismo dentário. Método: pesquisa com desenho observacional descritivo realizada por meio de questionários impressos entregues a 80 pais/responsáveis por crianças atendidas nas disciplinas de Clínica Infantil e Ortodontia I e II da Faculdade Avantis. A análise dos dados foi realizada de forma descritiva e com os testes Qui-Quadrado e Exato de Fisher. Resultados: a prevalência de pais que nunca receberam orientações sobre como porceder perante um traumatismo dentário foi de 75%, associando-se às respostas das perguntas: se saberiam como acondicionar o dente (p=0,001) e se já presenciaram alguma situação de trauma dental (p=0,047). As variáveis socioeconômicas escolaridade e renda e a autopercepção sobre o que fazer em uma situação de traumatismo dentário não se associaram a ter recebido informação sobre como proceder perante um traumatismo dentário, segundo o autorrelato dos responsáveis. A maioria dos pais das crianças nunca receberam informações e não sabem como proceder em caso de um possível traumatismo dentário. Conclusão: ter recebido informação sobre como proceder diante de um traumatismo dentário está associado a já ter presenciado situação de traumatismo dentário e a saber como acondicionar o dente para levar no dentista.

Authors: Shöngarth-Carías Roberto Ernesto , Pastrana-Sánchez Ricardo Antonio
Published: December 2019

El trabajo de investigación consistió en la recopilación de la Magnitud Límite Estelar (MALE) de Tegucigalpa, además de un dato adicional de Talanga, a fin de tener una referencia rural de comparación. Las magnitudes límites para la ciudad de Tegucigalpa desde diferentes ubicaciones arrojaron resultados de 2.98 (baja debido a contaminación lumínica en la zona), 3.56, 3.58 y 3.76. El promedio de la magnitud observada fue de 3.53 con una desviación estándar de 0.41. La mediana es de 3.56. Estos resultados nos indican que el cielo de Tegucigalpa es de cuarta magnitud en la escala de Bortle. Las condiciones en Talanga, cielo rural, mejoran hasta 4.68, lo que podría estimarse de una quinta magnitud, considerados cielos de transición entre periurbano y urbano. Las condiciones meteorológicas impidieron crear un registro estacional, particularmente sólo durante los meses de noviembre y enero se tuvieron condiciones reales de observación de buena calidad. En marzo se observa un cielo despejado, pero con condiciones de bruma debido a la quema de bosques que rodean la ciudad.

Authors: Cardona Amaya José Manuel
Published: December 2019

La palabra matrimonio como una fi gura jurídica ocupó un lugar importante en las relaciones civiles de la época colonial hondureña, sirviendo como el primer paso formal antes de la celebración del matrimonio y, por lo tanto, con sufi ciente peso legal para justifi car el inicio de un proceso dado su incumplimiento. En el presente artículo se explora la evolución de la validez jurídica de la palabra de matrimonio en los años finales de aplicación del derecho indiano en las colonias españolas, específi camente en la jurisdicción de la villa de Tegucigalpa y su Alcaldía Mayor. Para la investigación se utilizó el Fondo de la Alcaldía Mayor contenido en el Archivo Nacional de Honduras, encontrándose cinco casos referentes al objeto de estudio.
Propuesta de tipo Penal de desaparición forzada de Personas como Conducta Crimen de Lesa Humanidad para el Código Penal Costarricense
Authors: Salgado Mejía Rafael Andree
Published: December 2019

El propósito de este trabajo es analizar cómo se encuentra tipificado el crimen de lesa humanidad en el Código Penal de Costa Rica, con el objetivo de determinar si la desaparición forzada como conducta de crimen de lesa humanidad se encuentra bajo los parámetros internacionales de la definición de desaparición forzada. Asimismo, se demostrará que no se puede tipificar la desaparición forzada como delito y como conducta de crimen de lesa humanidad en un único tipo penal. Si bien es cierto, se hará alusión a principios, sentencias y normas, la postura epistemológica a utilizar será el formalismo jurídico porque nos centraremos en la normativa nacional e internacional. Finalmente, se harán algunas propuestas para tipificar la desaparición forzada como conducta de crimen de lesa humanidad en el Código Penal de Costa Rica.
Análisis filosófico-conceptual de la figura del neoconstitucionalismo como una clase de iusnaturalismo
Authors: Chavarría Lara Sebastián
Published: December 2019

Es un lugar común en las discusiones iusfilosóficas de nuestra época, afirmar que el neoconstitucionalismo se distingue de manera importante del tradicional derecho natural. El objetivo de esta investigación trabajo consiste en desvanecer las tesis que sustentan dicha creencia. Se sostiene, en cambio, que el neoconstitucionalismo puede ser entendido como una especie de la gran familia de iusnaturalismos que han aparecido a lo largo de la historia de la cultura jurídica occidental. Y, respecto del vetus iusnaturalismo, se demuestra que el neoconstitucionalismo se distingue únicamente por vía de las diferencias específicas dentro del genus iusnaturalismo.
Migrar y seguir cuidando: experiencias de mujeres migrantes de Nicaragua y Guatemala
Authors: Hernández Cordero Ana Lucía , Romea Martínez Ana Cristina
Published: December 2019

Propósito: La crisis de cuidados que afecta a países europeos como España ha desencadenado, en los últimos 10 años, un aumento de flujos migratorios femeninos procedentes de Guatemala y Nicaragua, entre otros. Estas mujeres migran para ocuparse de la atención a personas dependientes al mismo tiempo que dejan a sus familias en sus países de origen dando lugar a las llamadas familias transnacionales. El objetivo de este artículo es reflexionar sobre las estrategias que las migrantes utilizan para mantener el vinculo afectivo con sus seres queridos, y entonces continuar con sus labores de cuidados. Metodología: Con base en una metodología cualitativa, durante los años 2009 al 2016 hemos realizado entrevistas en profundidad a guatemaltecas y nicaragüenses que han migrado a España con el objetivo de trabajar y que siguen en comunicación con sus familias en sus ciudades de origen. Resultados: El análisis del material empírico refleja en primer lugar que las mujeres centroamericanas están migrando hacia España para dedicarse al empleo de hogar y los cuidados, en segundo lugar que la separación física de sus familias no es un impedimento para continuar con sus tareas de cuidado, en tercer lugar que importancia de las nuevas tecnologías de información y comunicación para el establecimiento de una proximidad relacional a través de las fronteras. Implicaciones: Este artículo pretende aportar nuevas informaciones a las dinámicas de mujeres centroamericanas en España, que se caracterizan por ser un colectivo migrante relativamente novedoso y por ende, poco estudiado hasta el momento.

Authors: Barbosa R. R. , Carvalho M.
Published: December 2019

A clear and direct guide for the design of a solar heating system is presented herein, focused on industrial applications. This guide focuses on the design of solar water heating systems for nonresidential applications. The importance of considering climatic conditions throughout the year is highlighted herein, along with reliable solar radiation data. Solar heating water systems are essential for the diversification of the Brazilian energy matrix and rationalization of the energy resources available. The system is initially dimensioned without the consideration of losses. Then, the required procedure to calculate thermal losses is described, and it is verified that the main losses occur in solar collectors and storage. After careful consideration of the hot water consumption profile and the results obtained in the calculation of the main thermal losses, the storage volume was doubled to guarantee the satisfaction of energy demands.
COMPARISON BETWEEN SINGLE AND DOUBLE INTEGRAL TRANSFORMATION SOLUTIONS OF HEAT CONDUCTION IN SOLID-STATE ELECTRONICS
Authors: Correa L. M. , Chalhub D. J. N. M.
Published: December 2019

The design of modern electronic devices has been dealing with challenges on thermal control. In this work, it is proposed two different ways of modeling the temperature field in Solid State Electronics (SSE) using integral transforms, with several heat generations in the domain of the microchip and external convection. Two proposed approaches solve the heat conduction formulation on the SSE using the Classical Integral Transform Technique (CITT): One performing a single transformation (CITT-ST) and the other performing a double transformation (CITT-DT). Both methodologies are compared and achieved similar results. The simpler analytical solution by CITT-DT contrasts with a complex and cumbersome analytical manipulation of CITT-ST. The results show that CITT-ST is more efficient to obtain the solution, requiring a lower truncation order, for the problem of heat conduction in Solid State Electronics even though it has a more complex formulation.
It Takes Two to Say ‘Hi’: Evaluating College Teacher/Student Greetings in Kuwait
Authors: Algharabali Nada A. , Akbar Rahima S. , Taqi Hanan A.
Published: December 2019

As mundane and empty expressions as they may seem, greetings are necessary social behavior for the establishment and maintenance of interpersonal relationships no matter what setting they occur in or who the interlocutors are. We hypnotized that greeting behaviors may especially be beneficial with college students in academic contexts. With a socio-pragmatic perspective in mind, the present study investigates the importance of caring classroom behavior between college students and teachers. Quantitative analysis elicited from online questionnaires analyzed via SPSS in search of significance across variables, such as gender, age, and social status, showed both students and teachers strongly believe that exchanging greetings are a crucial part of classroom interaction as it leads to the overall success of the relationship between them. In an era of achievement-oriented education, students are expected to pave their way efficiently towards potential professional levels needed in the job market. It is therefore essential that research exploring, even the most mundane aspects of teacher/student interaction, helps in tailoring to the students’ needs and interests.

Authors: Benali Asmae , El Asri Bouchra
Published: December 2019

Day after day, the number of mobile applications deployed on cloud computing continues in increasing because of smartphone capabilities improvement. Cloud computing has already succeeded in the web-based application, for that reason, the demand for context-aware services provided by cloud computing increases. To customize a cloud service that takes into account the consumer requirements, which depend on information change, it brings to light many recent challenges to cloud computing about environment-aware, location-aware, time-aware. The cloud provider, moreover, has to manage personalized applications and the constraints of mobile devices in matters of interaction abilities and communication restrictions. This paper proposes a strategy for selecting automatically an appropriate cloud environment that runs out whole requirements, defines a configuration for the associated cloud environment and able to easily adapt to the change of the environment on either the user or the cloud side or both. This process builds on the principles of dynamic software product lines, Agent-oriented software engineering, and the MAPE-k model to select and configure cloud environments according to the consumer needs and the context change.

Authors: Tan Fengmei , Zheng Silin , Wu Hongyan , Nie Lixia , Li Wenhua , Li Liping
Published: December 2019

Introduction: The study investigated the risk factors of phlebitis associated with infusion by peripheral intravenous catheter (PIVC).

Methodology: Hospitalized adults (n = 506) were placed with PIVCs by trained nurses. Rates of phlebitis were noted according to PIVC gauge, insertion site, and dwell time; and type and volume of infusion solution.

Results: The development of phlebitis appeared to be significantly associated with the size of the outer diameter of the PIVC. The rate of phlebitis among patients given a hypertonic infusion solution was significantly higher; and also associated with infusion volume. There was no difference in phlebitis development among insertion sites, and dwell times among these sites were comparable.

Conclusion: The risk of phlebitis increased with the PIVC size and volume of infusion solution, and use of a hypertonic solution. The recognition of risk factors and standardized intervention may reduce the occurrence of phlebitis associated with PIVC use.
Mechanical behavior of particle-reinforced polyurethane composites for load-bearing drives
Authors: Porąbka Anna , Archodoulaki Vasiliki-Maria , Laska Jadwiga
Published: December 2019

Two series of polyurethane composites were prepared using NDI- and MDI-based prepolymers and common polyol. NDI-based polyurethane is generally resistant to mechanical wear and rebound-resilient whereas MDI-based PU has cushioning and vibration damping features, and both types can be used as a matrix for load-bearing composites. The objective of this study was to compare the mechanical properties of composites containing 5% vol. of ceramic particles prepared with the use of the mentioned PU systems, and unmodified commercial materials. The effect of various ceramic particles on physical and mechanical properties was studied. The results showed that the mechanical properties changed in comparison to reference materials: E’ improved, and impact strength performed favorably in certain materials. Both the tensile strengths and the elongations at break of the composites were found to decrease with the content of ceramic particles; however, the hardness increased gradually. Since ceramic particles offer better stiffness and hardness, the selected composites could be a viable alternative to the pure commercial PUs available in the industry.
INFLUENCE OF STRUCTURAL-PHASE CONDITION ON
THE MECHANICAL-TRI BOLOGICAL PROPERTIES OF Ti3SiC2
COATINGS OBTAINED BY THE DETONATION METHOD
Authors: BUITKENOV Dastan , RAHADILOV Bauyrzhan , SAGDOLDINA Zhuldyz , KANTAI Nurgamit , KANTAI Nurgamit
Published: December 2019

The article provides the results of the research of the structure and properties of powder coatings based on
titanium carbosilicide Ti3SiC2 obtained by detonation spraying on the surface of tool steel U9/У9 (equivalent
to N9). Micro-indentation methods and abrasive wear tests for mechanical and tribological properties of
Ti3SiC2 based coatings were conducted. The microstructure of the coating has a layered structure. The border
between the coating and the base has a characteristic crinkled appearance. It was determined that the phase
composition of the coatings changes during detonation spraying is a result of the decomposition of Ti3SiC2
powder into titanium carbide and titanium carbosilicide (secondary phases). Selected consolidation conditions
ensure the formation of a Ti3SiC2/TiC composite material. The influence of the second phase content (TiC,
TiO2) on the properties of coatings was studied. Studies of the microhardness of samples with coatings showed
that, in the entire range of annealing temperatures, the microhardness of the Ti3SiC2/TiC composite material
increases compared to the coating before annealing. It was found that the maximum microhardness of the
Ti3SiC2/TiC composite material after annealing at a temperature of 800 ○C is explained by an increase in the
content of the Ti3SiC2 phase. It was established that, during detonation spraying of Ti3SiC2 powders, a coating
with a higher microhardness and wear resistance is formed.
EFFECT OF PRESSURE AND SLIDING SPEED ON THE FRICTION
COEFFICIENT OF POLYURETHANE ELASTOMERS (EPUR)
OF DIFFERENT HARDNESS DURING THEIR FRICTION
ON STEEL WHEN LUBRICATING WITH GREASE
Authors: CAPANIDIS Dymitry , SOKOLSKA Justyna
Published: December 2019

Polyurethanes (PUR) are widely used for some elements of machinery and equipment, including in motorized
shock-absorbing nodes and technical seals that can work in various operating conditions. The article presents
the results of tribological investigations of polyurethane elastomers (EPUR) with different hardness (75, 83,
and 93 °Sh A), which cooperated with steel in assembly lubrication conditions (mixed friction) with two
types of grease (showing low and high adhesion to steel), with variable values of unit pressure p and sliding
speed v. For the research, a rotary plan for two variables (p and v) was applied at five levels of their value.
Based on the results of the tests of particular associations, the regression functions of the form of the second
degree polynomial were determined, enabling the development of results in the form of spatial and contour
diagrams. Based on the results of tribological tests, recommendations for designers dealing with the design
and construction of friction junctions and seals in which polyurethane elastomers cooperating with steel
elements can be used.
THE EFFECT OF RESIDUAL STRESS ON THE LOAD BEARING
CAPACITY OF PVD COATED SURFACES – PART 2
Authors: CHRONOWSKA-PRZYWARA Kinga , KOT Marcin , SZCZĘCH Marcin
Published: December 2019

The article presents the results of modelling tests of the coating-substrate systems subjected to a contact
load using a spherical diamond indenter with a 20 μm tip radius. Systems with 1 to 5 μm thick CrN coatings
deposited on X5CrNi18-10 austenitic steel substrate were analysed. Systems without residual stress as well
as with introduced 2 and 5 GPa compressive residual stresses were analysed. The article presents the effect of
coating thickness on substrate deformations at load range up to 1 and 3 N. The evolution of maximum radial
stress in the substrate and the range of substrate plastic deformation for the assumed coating thicknesses
were also analysed. Modelling results showed a strong relation between maximum critical force and relative
coating thickness. The maximum radial stresses in the substrate in a case of systems with a thin 1 μm coating
are much smaller than for thicker 5 μm coating, referring to the relative coating thickness. However, the
analysis of substrate yielding showed that, for thin 1 and 2 μm coatings, substrates deform plastically at 0.01
and 0.03 N, respectively, while the 5 μm coating prevent plastic deformations up to load 0.32N.

Pinus sylvestris L. var. cretacea Kalen. In The ”Kreidova Flora” Branch of Ukrainian Steppe Nature Reserve: Current State and Conservation Measures
Authors: Spinova Yuliia , Kuchma Tetyana , Vyshenska Iryna
Published: December 2019

The "Kreidova Flora" (Cretaceous Flora) branch of Ukrainian Steppe Nature Reserve was created in 1988 to protect unique cretaceous vegetation, including pine forests on chalk. The Standing Committee of the Berne Convention in 2018 added these forests to the list of endangered habitats as “G3.4G Pinus sylvestris forest on chalk in the steppe zone“. For the last 40 years, the area covered with pine trees has doubled, but there are threats of invasive plants, periodical fires and other losses as a result of military actions since 2014. Satellite remote sensing data (Landsat archive) were used to analyze the distribution patterns and disturbances over 40-year period. The assessment of the stability and risks in this habitat shows its rareness, narrow prevalence, poor reproduction, very high (R> 83%) danger of destruction, and strong sensitivity to the environmental changes. Special set of monitoring and conservation measures are considered to provide successful protection of the habitat as a part of Emerald network.

Ciências da educação: especificidade epistemológica, objetividade e prática pedagógica
Authors: Devechi Catia Piccolo Viero , Bisol Benedetta
Published: December 2019

O artigo busca discutir as ciências da educação a partir de duas compreensões existentes nas discussões acadêmicas sobre o assunto: a ideia de enxugamento do estudo de tais ciências em favor do treinamento de habilidades necessárias para a prática educacional e em contraponto, a defesa da importância dessas ciências para a formação de educadores capazes de uma compreensão mais fundamentada da complexidade do fenômeno educacional, seja como processo individual, seja do ponto de vista social. Destaca dois momentos significativos na história do estudos pedagógicos através da referência a dois autores clássicos, a saber, Herbart e Dewey, analisando as questões de princípios, formatos e finalidades das ciências da educação no contexto atual, levando em conta as transformações sócio-política-econômicas mais recentes e o seu significado para a organização do sistema educacional, também nos seus aspectos pedagógicos. Conclui que se defendemos que a educação não tem apenas finalidades mercadológicas, mas também sociais, culturais e humanas, as ciências da educação deveriam se voltar para as demandas do mundo da vida, podendo encontrar na conversação discursiva a possibilidade de continuar cumprindo com o seu papel diante dos desafios sempre novos da formação humana.
What’s love got to do with it? improving the effect of marriage education
Authors: Chalmers Jennifer Harley
Published: December 2019

Meta-analytic research on the effect of marriage and relationship education (MRE) over the past forty years has identified only a small overall effect size on relationship quality measures within experimental-design studies. In an effort to increase the effect size of marriage education, this study introduced a new educational objective and measure within an eight-session, group-format course. The curriculum focused on developing habits to increase feelings of romantic love as a way to improve marital adjustment (Four Gifts of Love Class, FGL). Eleven couples (N = 22) residing in the Philippines were randomly assigned to FGL (G1) or delayed FGL-control (G2). The results demonstrated a large effect size on measures of marital adjustment (d = 1.11, p < .01) and romantic love (d = 0.68, p < .05). In addition, after G2 completed FGL, their gains matched the gains of G1, and the gains were sustained at the three follow-up periods.

Published: December 2019

The present study aims to examine inter-individual differences in adaptive number knowledge in secondary school students. Adaptive number knowledge is defined as a well-connected network of knowledge of numerical characteristics and arithmetic relations. Substantial and relevant qualitative differences in the strategies and expression of adaptive number knowledge have been found in primary school students still in the process of learning arithmetic. We present a study involving 879 seventh-grade students that examines the structure of individual differences in adaptive number knowledge with students who have completed one year of algebra instruction. Results of a latent profile analysis reveal a model that is similar than was previously found in primary school students. As well, arithmetic fluency and the development of arithmetic fluency are strong predictors of adaptive number knowledge latent profile membership. These results suggest that adaptive number knowledge may be characteristic of high-level performance extending into secondary school, even after formal instruction with arithmetic concludes.
Pragmática transcendental y filosofía social: Karl Otto Apel, Jürgen Habermas y la nueva fundamentación de la Teoría Crítica
Authors: Ortega Esquembre César
Published: December 2019

El objetivo de este artículo es defender que la pragmática transcendental ofrece la fundamentación normativa de la teoría crítica como teoría de la acción comunicativa. Para ello se expondrá en primer lugar el problema de la normatividad en la Teoría Crítica de la sociedad. Tras describir la forma que adquiere esta teoría tras el giro lingüístico operado por Jürgen Habermas, se reconstruirán en tercer lugar los elementos fundamentales de la pragmática transcendental apeliana y habermasiana. En cuarto y último lugar se mostrará que este modelo constituye la fundamentación normativa de la nueva teoría crítica.

The aim of this paper is to argue that transcendental pragmatics constitutes the normative foundation of critical theory, understood as theory of communicative action. To that end, the issue of normativity within Critical Theory discussions is first exposed. After describing the form this theory takes from the linguistic turn carried out by Jürgen Habermas, key elements of Karl Otto Apel´s and Jürgen Habermas´ transcendental pragmatics are thirdly reconstructed. Fourth paragraph shows that this model operates as the normative foundation of the new critical theory.
La centralidad ética del discurso
Authors: Damiani Alberto Mario
Published: December 2019

El objetivo del presente trabajo es explicar la relación entre las nociones de discurso y acción en un marco pragmático trascendental. El trabajo comienza con una presentación de la primera noción y de la idea de pretensión de validez. Luego son examinadas algunas objeciones a la justificación última de la ética, formulada por Apel. La conclusión es que es posible una respuesta a esas objeciones mediante la diferenciación entre dos niveles de la relación entre discurso y acción: un nivel fáctico y uno trascendental.

The aim of this paper is to explain the relation between the notions of discourse and action in a transcendental-pragmatic frame. The paper begins with a presentation of the first notion and the idea of validity claim. After that, some objections to Apel's ultimate justifications of ethic are examined. The conclusion is that an answer to these objections is possible throw the difference between two levels of the relation between discourse and action: a real level and a transcendental one.
A new Throne-Amulet from Hedeby
Authors: Kalmring Sven
Published: December 2019

In 2017 a throne-amulet made from bone, once retrieved from the diggings of harbour excavation 1979/80 in Hedeby, was committed to the Wikinger Museum Haithabu. It constitutes the second specimen known from the site and fits well into the larger group of throne-amulets known from south-eastern Scandinavia. The academic discussion of these amulets as devotional pagan objects either in connection with the worship of Óðinn or else as thrones of vǫlur is controversial. The piece from Hedeby harbour does not seem to depict the typical block-chair, though, but is about the first indication for the existence of Viking-age barrel-chairs used continuously until Early modernity.
The Guilty Feminist Army
Authors: Diddams Natalie
Published: December 2019

IN THIS PAPER, I DISCUSS THE AFFECTIVE POTENTIAL OF LAUGHTER IN THE HUGELY POPULAR COMEDY PODCAST SERIES; THE GUILTY FEMINIST. SPECIFICALLY, I EXPLORE HOW THE SOUNDS OF LAUGHTER – AS DISSEMINATED BY THE PODCAST – CAN LEAD TO EXPLOSIONS OF EMOTION IN THE PUBLIC SPHERE; SETTING THE BODY IN MOTION AND LEADING TO NEW WAYS OF THINKING, FEELING AND BEING. WHILE THESE PUBLIC EXPLOSIONS OF EMOTION CAN BE TRANSGRESSIVE, I POSTULATE THAT THEY CAN ALSO RELIEVE SOME OF THE TENSION CREATED BY THE NEGATIVE AFFECTS SWIRLING AROUND FEMINISM, WHICH, ACCORDING TO AHMED, “IS ALWAYS ASSUMED TO BE BRINGING OTHERS DOWN” (AHMED, 2010:65). USING GUATTARI’S IDEAS ON THE PRODUCTION OF SUBJECTIVATION, I ARGUE THAT THESE EXPLOSIONS CAN INTENSIFY THE EMERGENCE OF A GLOBAL, INTERSECTIONAL FEMINIST COMMUNITY, PROVOKING A CONSIDERATION OF HOW PODCASTS SUCH AS THE GUILTY FEMINIST COULD EXTEND OUR UNDERSTANDING OF THE USE OF TECHNOLOGY AND ONLINE ACTIVISM WITHIN CONTEMPORARY FEMINISMS.
Exploring the Affective Politics of Political Beauty
Authors: Landau Friederike
Published: December 2019

TO UNDERSTAND THE INTRICATE INTERCONNECTION BETWEEN POLITICS AND AFFECTS, I EXAMINE A PERFORMANCE OF THE BERLIN-BASED ARTIST COLLECTIVE ZENTRUM FÜR POLITISCHE SCHÖNHEIT (CENTER FOR POLITICAL BEAUTY, ZPS), IN WHICH ARTIST ACTIVISTS STAGED A HORSEBACK RIDE TO FASTEN A MANIFESTO OF TEN THESES OF POLITICAL BEAUTY ON THE FAÇADE OF THE GERMAN BUNDESTAG. INTERCONNECTING THEORIES OF POLITICAL DIFFERENCE (MARCHART 2010), WHICH DIFFERENTIATE BETWEEN THE ONTOLOGICAL REALM OF ‘THE POLITICAL’ AND ONTIC REALIZATIONS OF ‘POLITICS’, AND POLITICAL THEORIES OF AFFECT, I APPROACH THE AFFECTIVE DIMENSIONS OF POLITICAL DIFFERENCE AS AFFECTIVE POLITICS. BUILDING ON BARGETZ’S (2014) “POLITICAL GRAMMAR OF FEELINGS”, I SITUATE THE PERFORMANCE’S TEMPORARY INSTITUTIONS AND INTERRUPTIONS OF ‘POLITICS’ AND ‘THE POLITICAL’, AS WELL AS ‘FEELING POLITICS’ AND ‘POLITICS OF FEELING’ RESPECTIVELY, AS AFFECTIVE ENCOUNTERS TO EXPERIENCE OR ENACT POLITICAL BEAUTY. POLITICAL BEAUTY, IN AN ANTAGONISTIC FRAMEWORK THAT FOREGROUNDS CONTINGENCY, CONFLICT AND ABSENCE, MOBILIZES AFFECTS AS INHERENTLY AMBIVALENT AND CONTENTIOUS. AS A CHALLENGE TO THE DIAGNOSIS OF AN INEVITABLE POST-POLITICAL CONDITION, I DISCUSS THE POTENTIAL OF POLITICAL BEAUTY AS AFFECTIVE POLITICS TO POTENTIALLY RE-POLITICIZE POLITICS. BORROWING FROM DERRIDA (1994), I CONDUCT A SPECTRAL READING OF ZPS’ TEN THESES AND CARVE OUT THREE ANALYTICAL VIGNETTES – BEAUTY, VITALITY AND LONGING – TO CONCEPTUALIZE POLITICAL BEAUTY AS OSCILLATING BETWEEN THE DESIRE AND HOPE FOR POLITICAL CHANGE, WHICH CAN NEVER BE FULLY SATISFIED, AND A DISMISSAL OF (POLITICAL) UGLINESS AND DEATH. IN THE END, POLITICAL BEAUTY ESCAPES A DEFINITION BECAUSE IT IS, AFTER ALL, NOTHING BUT AN IMPOSSIBLE PROJECT FOR POLITICS AND AFFECTS OF AN UNKNOWN FUTURE.

L’aura du futur antérieur: la postmodernité et la fin de l’histoire
Authors: Lacasse Germain
Published: December 2019

Cet article analyse la comparaison que proposait Bill Readings entre l’objet-film comme représentation moderniste d’une histoire voulue universelle, et le temps cinématographique fragmenté et discontinu comme expérience postmoderne déconstruisant le grand récit de l’histoire positiviste.
Subsequent Precedence: Milton's Materialistic Reading of Ficino and Tasso
Authors: Grossman Marshall
Published: December 2019

In departing from Bill Readings' view that Milton's work inaugurated modernist history as lacking an inaugurating event, this essay engages the metaleptic articulation of origin and terminus, meaning and signifier, in some of Milton's prose and explores the rhetorical performance of Plato's idea of the icastic imagination, which convinced Milton that writing poetry is socially productive labor.
SCHRIFT/SCHREIBEN ALS TRANSGRESSION. WALTER BENJAMINS KONSTRUKTION VON GESCHICHTE(N)
Authors: Barck Karlheinz
Published: December 2019

L’auteur réévalue la pertinence des travaux de Walter Benjamin dans le contexte des débats théoriques contemporains et propose une réorientation des études sur Benjamin. S’appuyant sur l’hypothèse de l’unité historique et philosophique du « programme » de Benjamin — du « fragment théologique-politique » aux « thèses sur la philosophie de l’histoire » —, Barck réinterprète la théorie et la pratique de l’écriture benjaminiennes. La théorie du langage qui fonde sa philosophie de l’histoire étant largement influencée par les idées de Benjamin sur l’écriture (Schrift/Schreiben), Barck développe plus particulièrement les trois problématiques suivantes : le babelisme en tant qu’indice de confusion linguistique, la magie du langage et la manifestation (Darlegung) comme acte d’écriture dans l’écriture comme medium. Reprenant la terminologie de Benjamin, Barck situe sa pensée dans un contexte international et interdisciplinaire et souligne les affinités de celle-ci avec les oeuvres de Marcel Jousse, Erik E. Havelock et la Toronto School of Communication.
AHAB AS CAPITALIST, AHAB AS COMMUNIST: REVISING MOBY-DICK FOR THE COLD WAR
Authors: Murphy Geraldine
Published: December 2019

Contrasting F.O. Matthiessen's and R.W.B. Lewis's interpretations of Moby-Dick and Melville's later novels (in American Renaissance and The American Adam respectively) with Richard Chase's revisionist rebuttal (in Herman Melville: A Critical Study), the author describes literary discourse on Melville as an important site, in American Studies, to exorcise the old left and redefine liberalism in the postwar period.
L’ESPIONNAGE DE PAPIER : RÉVÉLATION & REPRÉSENTATION DE CONNAISSANCES
Authors: Bleton Paul
Published: December 2019

CULTURE AND THE HUMANITIES: SYMPTOMATOLOGIES, MOSTLY HISTORICAL, MAINLY GERMAN
Authors: Pfeiffer K. Ludwig
Published: December 2019

Against the backdrop of hermeneutics and German Romanticism, this essay traces the institutional, historical, and conceptual contours of the notion of Geisteswissenschaften. In this context, it concentrates on the conceptions of Kant, Fichte, von Humboldt, and, at greater length, on Dilthey's efforts to use a notion of Geist to meld together life, theory, and the institution. It then plots the transition from a concern with Geist to a concern with Kultur.

More Enlightened Than Thou: The Dangers of Idealizing Knowledge in the Disciplines
Authors: Cecil Wes
Published: December 2019

In the context of the university's current identity crisis, this essay analyzes the implications of creating a "post-disciplinary" university. A critical discussion of texts by Frank Lentricchia, James Sosnoski, and Judith Butler reveals the institutional and epistemological stakes of postdisciplinary views of the University structure. Against this backdrop, the essay concludes by showing how idealizing knowledge as separable from all strife leads to a systematic underestimation of the disciplines' importance for the philosophical, physical, and administrative structures that undergird the university and the disciplines themselves.
Colonialism, the Cold War Era, and Marginal Space
Authors: Tay William , Yeh Michelle
Published: December 2019

Besides proposing various possible reasons for the non-existence of a literature in English from the British Crown Colony of Hong Kong, this paper tries to explain how the Cold War and the ideological struggles between the Nationalists and the Communists allowed and promoted the growth of literary writings in Chinese. But very often these works tended to speak to the centers (China or Taiwan) from the marginal space of Hong Kong.
