Objective

To examine demographic and clinical characteristics associated with diagnostic delay in psoriatic arthritis (PsA).

Methods

We characterized a retrospective, population-based cohort of incident adult (≥ 18 yrs) patients with PsA from Olmsted County, Minnesota, from 2000–2017. All patients met the classification criteria. Diagnostic delay was defined as the time from any patient-reported PsA-related joint symptom to a physician diagnosis of PsA. Factors associated with delay in PsA diagnosis were identified through logistic regression models.

Results

Of the 164 incident PsA cases from 2000 to 2017, 162 had a physician or rheumatologist diagnosis. Mean (SD) age was 41.5 (12.6) years and 46% were female. Median time from symptom onset to physician diagnosis was 2.5 years (IQR 0.5–7.3). By 6 months, 38 (23%) received a diagnosis of PsA, 56 (35%) by 1 year, and 73 (45%) by 2 years after symptom onset. No significant trend in diagnostic delay was observed over calendar time. Earlier age at onset of PsA symptoms, higher BMI, and enthesitis were associated with a diagnostic delay of > 2 years, whereas sebopsoriasis was associated with a lower likelihood of delay.

Conclusion

In our study, more than half of PsA patients had a diagnostic delay of > 2 years, and no significant improvement in time to diagnosis was noted between 2000 and 2017. Patients with younger age at PsA symptom onset, higher BMI, or enthesitis before diagnosis were more likely to have a diagnostic delay of > 2 years, whereas patients with sebopsoriasis were less likely to have a diagnostic delay.
Fortunato de Selgas y San Julián de los Prados. La síntesis del debate de la restauración monumental en España a principios del siglo XX
Authors: García Cuetos María Pilar
Published: February 2021

La actuación de Fortunato de Selgas en San Julián de los Prados, Oviedo, sintetiza el debate sobre la restauración monumental en España a principios del siglo XX. Integra elementos de la restauración estilística, limitada por el racionalismo arqueológico, el avance de las teorías italianas de la restauración histórica y boitiana y la influencia de la estética ruinista y de la llamada sinceridad arqueológica. Unas fotografías inéditas de 1932 nos devuelven la imagen perdida de la iglesia tras la intervención y nos permiten conocer uno de los ejemplos más interesantes de la restauración española de principios del siglo XX, desgraciadamente alterado por intervenciones posteriores.
La cultura urbana como espectáculo: la experiencia de modernidad en la Exposición Internacional de Barcelona 1929
Authors: Rodríguez Granell Ana
Published: February 2021

Este artículo propone una mirada renovada sobre la Exposición Internacional de Barcelona 1929 a través de su cultura material y visual, los pabellones comerciales, sus atracciones y la configuración de su espacio para analizar cómo el diseño del evento se interrelaciona con varias dinámicas inscritas en la cultura urbana y a la experiencia de modernidad. Veremos así la centralidad que cobran las experiencias sensitivas, cómo el régimen visual del evento se relaciona con la circulación de saberes en el siglo XIX o que vínculos establece el consumo con la creación de nuevos espacios urbanos, nuevas formas de entretenimiento y estilos modernos como el Art Déco. El objetivo será visualizar el alcance del evento de 1929 en la concreción de culturas urbanas asociadas a la irrupción de la sociedad de consumo que se intuyeron en 1888.

Concevoir une formation en ligne à partir d’une étude sur les enjeux interculturels des ingénieurs
Authors: Le Forestier Mélanie
Published: February 2021

Dans cet article, nous présenterons le processus de conception d’une formation en ligne appelée POMI (Préparer et Optimiser sa Mobilité Internationale) destinée à des élèves-ingénieurs, mais qui peut être transposée dans d’autres contextes de formation. Le principal objectif pédagogique est d’accompagner les apprenants dans le développement d’une démarche interculturelle en s’appuyant sur leur expérience de mobilité internationale, obligatoire en formation d’ingénieur. La particularité de ce projet a été d’articuler ce travail d’ingénierie pédagogique à une recherche visant à identifier, au préalable, les besoins spécifiques des formations d’ingénieur en matière d’interculturalité. Nous proposons donc une conceptualisation du développement interculturel dans un modèle de « démarche interculturelle » qui a permis de construire un dispositif de formation adapté aux enjeux interculturels rencontrés par les ingénieurs professionnels. En première partie d’article, nous préciserons la façon dont nous nous saisissons du champ de l’interculturalité et comment cela nous a permis de proposer une conceptualisation de ce que nous appelons une démarche interculturelle dans un contexte ingénieur. Nous montrerons ensuite comment le modèle de démarche interculturelle a servi à construire le scénario et le cheminement pédagogique du dispositif POMI. La formation étant toujours en cours de construction, nous conclurons l’article en présentant la pédagogie privilégiée et qui correspond à celle que nous proposons aux enseignants et responsables pédagogiques qui souhaitent intégrer la dimension interculturelle dans leur pratique enseignante.

Natural rubber foam is used in industries as a gasket and insulation product. Dimensional expansion of specimen is the crucial problem of rubber foam specimen, especially in the automotive parts assembly. This work aims to understand the behavior of natural rubber foam (NRF)/carbon composites on microstructure and properties of NRF before being used. Carbon was synthesized from durian bark which was the agricultural waste that had the potential for using as reinforcing filler. The result showed the fast sulfur vulcanization rate with small bubble size at high amount of carbon. In addition, the young modulus of NRF/carbon composites increased with increasing carbon content.
Innovative Surface Technologies to Create Protective Functional Coatings on Light Metal Alloys
Authors: Hou Feng Yan , Mardon Ian , Dong Jun Zhe , Goode Chris
Published: February 2021

Weight reduction in automotive and aerospace components can improve energy efficiency, reduce emissions, and increase performance. The adoption of light metals such as aluminium, magnesium and titanium alloys, is essential to these performance improvements; however, these alloys require protective surface coatings to prevent corrosion and resulting mechanical failures during service life. Traditional protective coatings for light-weight materials can be costly in terms of energy, raw materials, and environmental sustainability. New durable coating approaches are required to allow light-weight materials to be fully exploited in high performance applications. Novel Cirrus HybridTM coatings, a recent innovation in surface finishing, can protect a wide range of light metal alloy components using a sustainable, non-toxic process. Cirrus HybridTM coating technology deposits a thin-film, inorganic coating that bonds tightly to the light-metal alloy substrate. The process is energy efficient, does not rely on hazardous chemicals, and is up to 5 times thinner than traditional coatings for light metals. A Cirrus HybridTM coating provides excellent anti-corrosion, scratch, and wear properties, along with superior tribological, electrical, and optical performance. This paper updates the art of these innovative new coating technologies for reducing weight in industrial components without compromising functionality or performance.
Effects of 1,2-Dihydro-2,2,4-Trimethyl-Quinoline (TMQ) Antioxidant on the Marshall Characteristics of Crepe Rubber Modified Asphalt
Authors: Bahruddin  , Wiranata Arya , Malik Alfian
Published: February 2021

The use of natural rubber-like crepe rubber as an asphalt additive is very susceptible to aging. Aging on asphalt crepe rubber can occur during the mixing process or its use for the road. Studies on the prevention of aging on asphalt are still being developed to produce asphalt resistance to aging and have good performance in preventing deformation. Some studies that have been done are the addition of other additives such as antioxidants. This study aims to study the effect of adding crepe rubber and the antioxidant 1,2-dihydro-2,2,4-trimethyl-quinoline (TMQ) to the Marshall characteristics of rubber asphalt. Preparation of the rubber asphalt sample begins with making crepe rubber, which is by milling raw natural rubber in the form of a cup lump using a creeper. The crepe rubber product contains dry rubber content of more than 95%. Then the crepe rubber masticated using an open mill to soften and form it with 2 mm thickness. Then the crepe rubber is melted at 200 °C before being mixed with asphalt, heated to 165 °C. The crepe rubber content in the asphalt mixture is made 10%, and during the mixing process, the TMQ was added with contents of 0%, 1%, 2%, 3% w/w. The rubber asphalt samples were then tested for their penetration and marshall characteristics, using ASTM D5 and ASTM D6927 standards. The test results show that the addition of the TMQ can improve the penetration properties and stability of the rubber asphalt in holding the load. However, the addition of the TMQ of more than 2% causes a decrease in the rubber asphalt's stability properties. The best results were obtained by adding 2% TMQ with 68.7 dmm penetration and optimum asphalt content of 5.50%. Results of the marshall test for the sample are marshall stability 1403.96 kg, void filled aggregate (VFA) 75.90%, void in a mixture (VIM) 3.07%, void mineral aggregate (VMA) 15.34%, flow 3.370 mm, and marshall quotient (MQ) 420.8 kg/mm.

Published: February 2021

The material of FA Nagan Raya (FANR) is the alternative base material in geopolymer generated from the power plantation, Nagan Raya, Acheh, Indonesia. It was recorded that the volume of FANR material is abundant in the landfill so that it impacted on the environment. It was due to there was no investigation to evaluate the waste of FANR to be a material in the concrete. This study interested to evaluate the material of FANR to be a base material in the geopolymer referring to the analyses of XRF, XRD, SEM, FTIR, and TGA. The results showed that the material of FANR was rich in Si and Al content that contributed to the mechanical properties. While the chemical content of Ca contributed to the setting time in the geopolymer system. The XRD analysis showed that the FANR particle and binder of a geopolymer were categorized as the crystalline material. It was supported by the FTIR analysis that showed the good chemical bond of Si-O-Si and Si-O-Al. The SEM analysis showed that the particle shape of FANR was a sphere with the misty surface. This particle shape caused the absorption of a more alkaline solution to maintain the workability in the fresh geopolymer. It was supported by the analysis of TGA that showed more water in the FANR geopolymer binder. It concluded that the material of FANR is eligible to be used as the base material in the geopolymer system.

Published: February 2021

As the world population continues to increase, so does the demand for raw materials to produce basic needs of the human race. One of the areas where this pressing demand for means of production is evident is in the production of concrete materials for building construction and infrastructure. The source of constitutive materials for concrete production, such as cement and aggregates are fast shrinking across the nations of the earth, and there is an urgent need for substitutes that will guarantee the availability of this essential material to the built environment sector of the economy. One of the trending approaches is the adoption of waste materials as a replacement for some of the constitutive materials of concrete. This research reviews past works on the use of recycled plastic waste and periwinkle shells for the production of lightweight aggregate concrete. The results of this review showed that the adoption of a reduced percentage of waste plastic in concrete leads to acceptable strengths for lightweight concrete, economy, efficient energy and excellent crack resistance. The use of periwinkle shell is beneficial for satisfactory strengths for normal aggregate concrete and for lightweight aggregate concrete, excellent resistance to heat and economy. This approach is sustainable as a means of recycling and will facilitate the actualization of the sustainable development goal “Responsible Production and Consumption”, (SDGs 12). There is a perspective that combining these two waste materials will lead to improvement towards achieving sustainable concrete.
Kameradan Yansıyanlar: Thomas Glavinic'in Kameralı Katil Romanı Örneğinde Toplum ve Medya İlişkisi
Authors: KIRGIZ Şenay
Published: February 2021

Teknolojik anlamda yaşanan her gelişme, toplum üzerinde oldukça etkili olabilmektedir. Medyada bu etkileşim neticesinde yeni bir gelişime doğru ivme kazanır. Günümüzün gazete, radyo, televizyon, dergi gibi basın yayın organları, toplumun ihtiyaçlarını karşılamayı kendine görev edinmeye başlar. Toplum medya tarafından servis edilen bu kurgusal dünyayı gerçek dünyadan ayırt edemez ve hayata bakış açısını bu kurguya göre şekillendirir. Çalışma, 1972 doğumlu Avusturyalı yazar Thomas Glavinic’in Der Kameramörder [Kameralı Katil] adlı romanını merkeze alır. Roman, paskalya tatillerini arkadaşları olan bir çift ile geçirmek için Avusturya’nın eyaleti Stirya’ya giden genç bir çift üzerine odaklanır. Başlarda normal hatta eğlenceli bir seyirde devam eden tatil süreci, bulundukları bölgede yedi ve sekiz yaşlarında olan iki kardeşin cinayete kurban gitmesi ile farklı bir boyuta taşınır. Kameralı Katil romanının medya bağlamında ele alınmasını elverişli kılan şey, romanın ilerleyen evrelerinde öğrendiğimiz üzere katilin tüm cinayet boyunca yaşananları kameraya almasıdır. Cinayet kasetinin özel bir televizyon kanalında yayınlanması ile birlikte cinayet, genç çift ve arkadaşları dâhil herkesin merakla takip ettiği kitlesel bir olaya dönüşür. Protestolar, kaseti yayınlayan özel medya kuruluşu ekseninde yaşanan etik tartışmalar ve hatta siyasi gerginliklere kadar uzanan bu süreçte, herkesin arzuladığı tek ortak şey katilin kimliğinin ortaya çıkmasıdır. Çalışmada, roman özelinde medyaya malzeme olan bir olayın, toplum ekseninde nasıl sansasyonel bir hal alabileceğini örneklemek ve sansasyonel olaylar karşısında romanın topluma, medyaya ve kamuya bakışını ölçmek amaçlanmıştır. Çalışma, metin odaklı bir yaklaşıma sahiptir.
İhtiyaçlar ve Tüketim Kültürü
Authors: SEVER Mustafa
Published: February 2021

Yaşanan süreçte teknolojinin imkânları kullanılarak iletişim araçlarından haberler, reklamlar, diziler vd. yollarla yayılan bilgi, davranış ve yaşama şekli örnekleri, toplumsal yaşamı biçimlemektedir. Çok uluslu şirketler marifetiyle gelişmiş kapitalist ülkelerin kültürü ve dolayısıyla değerler sistemi dünyada hâkim kültür şekline dönüşmektedir. Batı ülkelerinden dünya ülkelerine güler yüzlü bir eda ile sunulan tüketim kültürünün hâkimiyetindeki insanların ihtiyaçları da tabiî olmaktan anormalliğe yönelmektedir. Tabiî ihtiyaç, insanın karşılamadığı zaman bedenen ve zihnen üreticiliğinden uzaklaşacağı, kendine, ailesine ve topluma karşı ödev ve sorumluluklarını yerine getiremeyeceği yokluktur, sıkıntıdır. Kişinin istek, arzu ve özenmesiyle meydana gelen ihtiyaçlar ise, yapay ihtiyaçtır, lükstür. Yaşanılan süreçte insan, hayatını insanca, tabiî şekilde sürdürmek yerine, tüketmek için yaşayan bir varlığa dönüşmektedir. Bu süreçte çok uluslu şirketler, insanların sahip olma, tüketme, statü elde etme vd. isteklerini canlı tutarak küresel ölçekte üretilen ürünlerin tüketilmesini sağlamaktadırlar. Moda ve reklamlar yoluyla gereksiz, olmasa da olur türünden insan isteklerini, insanların temel ihtiyaçlarıymış gibi sunan ekonomik yapı, böylelikle kendi işleyişini de sağlamaktadır. Bu durum karşısında akıl, mantık, inanç ve irade sahibi her insanın ihtiyaçlarını doğru teşhis etmesi, “gönüllü basitlik yaklaşımı”nı benimsemesi gerekir. Bu yolla çevreye (insana ve tabiata) saygılı ve koruyucu etkinlikte bir tüketim gerçekleşecektir ki bu da insanî olandır. Çalışmamızda, ihtiyaç ve tüketim kültürü ilişkisinin tüketici davranışları üzerindeki etkenleri irdelenmiştir.

Böylece eserin Türk edebiyatı ve toplumsal cinsiyet çalışmaları arasındaki yeri tespit edilmeye çalışılmıştır.
Oh Ageism Up Yours! Female Perspectives of Ageing and Punk Identities Across the Lifecourse.
Authors:   , Willmott Alison
Published: February 2021

The experience of ageing is relevant to everyone. Yet, older people in western societies are subject to cultural expectations that influence the way they act, look and spend their time. Ageing women are subject to gendered expectations throughout their lives, with the expectation to be ’age-appropriate’ expanding beyond appearance to incorporate the way that older women live their lives and the places they go. If ageing means that women are meant to restrict the way they live their lives, what is it like? Ageism and expectations of age are powerful, but there are parallel influences. The study takes the legacies and influences of punk culture as a tool for the examination of age. As a subculture characterised by an anti-authority attitude, and a resistance to convention, women who identified with punk may be better equipped to resist conforming to wider cultural expectations of ageing. The study takes a feminist, qualitative approach to explore the experiences of women aged fifty to sixty-five who identified with punk, using the theoretical framework of cultural gerontology. Nineteen women were interviewed using semi-structured interviews, and themes identified using thematic analysis. Five themes were identified: ‘Everyday Ageism’, ‘The Punk Toolkit’, ‘The Feminist Toolkit’, ‘Work and Retirement’ and ‘Health’. The research concludes that the women in the study juxtapose their ageing experiences with a punk ethos, which remains of significance across the ageing lifecourse and is drawn upon, providing a sense of continuity. Moments of conformity occur across the lifecourse but do not disrupt an innate punk ethos. However, ageist cultural pressures remain powerful and this often results in a time-consuming inner narrative, negotiating ageist notions of ‘age-appropriateness’ with punk resistance to convention and conformity. Three concepts are introduced: the ‘Punk Toolkit’, the ‘Feminist Toolkit’ and the ‘Ageist Forcefield’, alongside recommendations for their use as practical tools in the ageing lifecourse, and to facilitate further research and reflective practice.
Selected Variables and Educational Expectation Among Secondary School Students in Trinidad
Authors: Baksh Ishmael
Published: February 2021

It is generally accepted that in the United States and other modern industrial societies there is a link between formal schooling (number of years of formal education) and social mobility, though some scholars such as Anderson, Blau and Duncan, and Jencks have disputed the strength of this link. The study of educational plans (or "educational expectations") of secondary school students in such societies derives its significance in part from findings of social scientists such as Hauser and Sewell et al. that a positive relationship exists between educational expectation and educational achievement, the latter being measured by number of years of formal schooling received. In order words, the investigation of educational expectation is valuable partly because it is a predictor - albeit a somewhat crude one - of ultimate educational achievement and hence socio-econmic status.

Bishops and People: Looking for Local Religious Life in Late Antiquity
Authors: Kahlos Maijastina
Published: February 2021

The religiosity of late antique and early medieval communities in the Mediterranean world has been vigorously examined and debated. This religious life has been called (among many other terms) ‘popular Christianity,’ ‘local Christianity,’ the ‘second church,’ ‘Religion zweiter Ordnung,’ and ‘the third paganism.’ In my article, I analyse late antique religious life from the viewpoint of encounters—between the ideals of the ecclesiastical elite and the people’s local cultic practices. These practices, embedded in the local communities, varied by regions but we can see similarities in the interaction of bishops with their local population. I will show how the ecclesiastical writers portrayed local cultic practices in negative terms as another religion (‘paganism,’ ‘idolatry,’ ‘demonic/ diabolic practices’), divergent from their own (‘Christianity’), or even as a distortion beyond ‘proper’ religion (‘magic’, ‘superstition’, ‘sacrilege’). In my analysis, I discuss and test various approaches that scholars have developed to understand the tensions between the bishops and the local people: David Frankfurter (local religion), Rubina Raja and Jörg Rüpke (local lived religion), and Nicola Denzey Lewis (magic as lived religion), Lisa Kaaren Bailey (lay religion) and Lucy Grig (popular culture). My focus is on the western Mediterranean world from the fourth to sixth centuries, and the cases of polemical encounters I analyse come from the writings of North Italian, Gallic and Hispanic bishops (Paulinus of Nola, Maximus of Turin, Philaster of Brescia, Caesarius of Arles, and Martin of Braga). I also compare the North Italian, Gallic and Hispanic situations with those in North Africa depicted by Augustine of Hippo.
Relationship among the Actors and Levels of Trust in Secondary Education Centers of the Guayaquil Canton (Ecuador)
Authors: Franco Pombo Mónica Rebeca , Fernández Martínez María del Mar , Luque de la Rosa Antonio , Gutiérrez Cáceres Rafaela
Published: February 2021

The public policy of Ecuador has placed the improvement of educational quality as one of the main objectives of government management. The climate-school constructs, organizational climate, work climate, and institutional climate, are used in different environments to accentuate the importance of the relationship established between a management environment ­ factor and the quality of results in organizations.

Throughout this study, the objective has been to analyze the variations in the relationship among the actors, and the levels of trust between the actors of the school organizational climate, according to the socioeconomic level, the role played in the educational community, or the type of socio-educational center. 

The study follows a new approach of an experimental, descriptive-comparative investigation, using techniques such as the survey, the interview, and the discussion group, adjusting to the mixed methodology according to the objectives and sense of the research proposed.

In consideration of the results, we will appreciate that the relationships between the actors and the confidence levels of the actors show mostly positive indicators based on the responses of the participants in the study. However, the percentage of negative perceptions (24.34%) is a factor to consider, since it might suggest that these perceptions underlie indicators of distrust that should be taken into account for any future interventions.

In conclusion, the schools participating in this study have built a mostly positive school organizational climate, which generates favorable spaces for innovation and change processes.
Data Driven Learning and teaching of prepositions in ESL: A study of Arab learners
Authors: Alshammari Sahal R
Published: February 2021

This paper explores the effectiveness of data driven learning approach in teaching prepositions to Arab learners. English prepositions have been reported to be a typical feature to learn by the Arab ESL learners. Moreover, intermediate or advance level learners have also reported their difficulties in the usage of English prepositions; reasons might be perceptual and cultural differences bet the two language communities. Teacher trained materials prepared from online resources along with TPP corpus, the aim of the present study was to compare DDL and traditional prescriptive rule based method of grammar teaching. Two distinct classes; experimental (n = 41) and control (n = 19) groups were formed who were study English major. Standardized test was conducted as a pre-test to ensure participants equal level of proficiency in using prepositions. During the study duration for a semester, experimental group was exposed to teacher-prepared materials along with TPP to see prepositions in context. Moreover they were asked to explore further through the prepared materials to reinforce their learning from the data. A post-test was administered at the end of the course. The results showed that the experimental group outperformed the control group. It was found that learners’ active role to direct their own learning process caused this encouraging outcome and better learning experience for the learners.

La Carta Social Europea y los derechos sociales emergentes: una aproximación al derecho de acceso a la información ambiental
Authors: Martínez López-Sáez Mónica
Published: February 2021

La protección de los derechos sociales constituye, hoy en día, un fin primordial, y en Europa, la Carta Social Europea Revisada juega un papel relevante como guardiana del modelo del Estado social, como verdadera Constitución Social de Europa y como el estándar de protección más elevado de los derechos sociales, en general, y de los derechos sociales emergentes, en particular. Así, resulta de especial interés estudiar el derecho de acceso a la información ambiental como derecho social emergente derivado, en gran parte, del genérico derecho a un medio ambiente sano. Este derecho se puede definir, en términos muy simples, como el derecho del público en general a recibir información relacionada con el medio ambiente. Este derecho no es una mera exigencia del Estado social, sino que constituye un mínimo vital y necesario para la dignidad inherente al ser humano, para hacer efectivo el ejercicio de los demás derechos y libertades, dependientes, en mayor o menor medida, por el medio ambiente y la información disponible del mismo. El presente trabajo analiza la materialización y evolución normativa y jurisprudencial de este derecho así como su reconocimiento y efectividad a través de la Carta Social Europea y la interpretación que hace su órgano de control, el Comité Europeo de Derechos Sociales, aludiendo a las convergencias y divergencias entre los sistemas de protección, e impulsando la necesaria y prioritaria aplicación de la CSE en virtud del principio favor libertatis.
La recuperación de la universalidad de la asistencia sanitaria tras el Real Decreto-ley 7/2018, de 27 de julio
Authors: López Insua Belén del Mar
Published: February 2021

El derecho a la salud se configura, dada su equivocada ubicación en el texto constitucional, como un principio rector de la política social y económica (artículo 43 de la CE) al que se le otorga una debilitada protección que no queda exenta de críticas. Son muchos los vaivenes que, en torno a esta materia, ha protagonizado la doctrina del Tribunal Constitucional. Sin embargo, lo cierto es que a pesar del constante tira y afloja, el derecho a la salud se ha erigido en pilar fundamental para la construcción de un constitucionalismo democrático-social que pretende dar primacía a los ciudadanos (derecho subjetivo) frente a los intereses económicos y mercantilistas propios de sociedades poco inclusivas. Por todo ello, al derecho a la salud se le otorga y reconoce (tanto en la normativa internacional, como en la comunitaria) el carácter de derecho primario y fundamental vinculado al derecho a la vida, a la integridad física y la dignidad de toda persona.  En esta línea, se sitúa el Real Decreto-Ley 7/2018, de 27 de julio, sobre el acceso universal al Sistema Nacional de Salud. Y es que, gracias a esta normativa, el derecho a la asistencia sanitaria se configura ahora como un derecho de ciudadanía, de carácter universal y no solamente ligado a la nacionalidad y a la residencia legal, por lo que el mismo se hará igualmente extensible (aunque con alguna limitación) a las personas que se encuentren irregularmente en España.

Se trata de una cuestión básica ya que en ella pueden residir las claves para saber hacia dónde deben ir dirigidas las propuestas de políticas públicas para el desarrollo de este derecho fundamental. En este proceso, además, resulta clave la necesidad de ir complejizando la cuestión. Así, se tratarán cuestiones tales como: las semejanzas y diferencias entre las nociones de vivienda y hogar; el significado de la introducción del adjetivo “digna”; sobre el por qué en sí mismo de la necesidad de añadir adjetivos al derecho. Trataremos de dilucidar medidas que permitan asegurar mecanismos para que cualquier persona tenga la posibilidad efectiva y material de acceder a un espacio en el que desarrollar una vida que merezca la pena ser vivida, independientemente de cómo se califique dicho espacio.
La responsabilidad social corporativa en Cuba ¿Nota sintónica para la prevención de riesgos en el trabajo?
Authors: Feria Galbán Karel
Published: February 2021

El presente artículo constituye un acercamiento a la responsabilidad social corporativa y su imbricación con la prevención de los riesgos laborales. Tema que ha sido poco tratado en las ciencias jurídicas teniendo mayor discusión en los ámbitos económicos y empresariales. En Cuba resulta casual y poco conocido entre los que se dedican a la investigación jurídica, no así entre los operadores que asesoran empresas, a quienes la Institución en debate les toca más de cerca, justo por las funciones que desarrollan. Es precisamente a través de esta presentación que se vinculará el trabajo de dos pilares que tienen relación directa en el asesoramiento a las personas jurídicas. De lo que se tiene y a lo que se aspira es el objetivo de esta investigación, teniendo como contexto el Derecho Laboral cubano.
The Unification of Product Life-cycle and Industry Life-cycle: A Framework for Telecom Sector in Pakistan
Authors:   Greenwich University, Karachi., Sibghatullah Amena
Published: February 2021

The purpose of this study is to propose a strategic framework using the Unified Life Cycle (ULC)model by combining Product lifecycle (PLC) and Industry life cycle (ILC). Data collection and analysis involves multi-stage qualitative methods. At first stage qualitative data was collected through interviews and focus groups while at a later part of the research qualitative data was again collected from the marketing experts (N = 100). This paper shows originality on many counts. Firstly, both PLC and ILC have shown weaknesses and limitations in earlier researches. This research has unified both PLC and ILC into one ULC combining the strengths and reducing the weakness of both life cycles. Secondly, earlier studies failed to provide any integrated strategic framework of selecting appropriate pricing strategies; using both PLC and ILC in silos. The current research provides an integrated strategic framework for pricing strategy selection using newly proposed strategic framework labelled as ULC.

Almost every individual is to face the challenge of the occupational choice problem at one or another time. However, students are particularly to encounter such problem while the selection of study programmes. It is widely believed, particularly by students, that selection of study programmes is the major factor, which leads the students to struggle for their desired future career. This study attempted to explore the roles of mothers, fathers, tutors, future income, future status, and societal difference by labelling all of such factors as “Influencers” on the career choice of young students. From this perspective, cross-sectional data based on primary data collection was gathered from different university students based in Karachi via a developed questionnaire and through nonprobabilistic convenience sampling. The gathered data was, subsequently, analyzed through one sample t-test and one way repeated Measure ANOVA by employing SPSS statistical package. The result of the study highlighted the relative importance of various career choice influences & that averages of variables of influence are statistically different F (4.215, 699.727)= 27.405, p<o.o5. These results could be used to make the student opt the right career path and excel in the desired domain.

Published: February 2021

The study of the relaxation of edge dislocations (ED) in metals under the action of alternating external stresses of various natures is of great practical interest for estimating of workability of structural elements and functional materials of nuclear power and thermonuclear fusion power plants. In the model of the inhomogeneous dissipative sine – Gordon equation for different values of the amplitude and frequency of the external harmonic force, as well as for different values of dislocation friction, the nonlinear dynamics of ED with fixed ends is studied numerically. The formation of breather-type solitons on the ED is shown, the maximum amplitude of which decreases with increasing dislocation friction. The resonance dependence of the kinetic energy of ED oscillations on the frequency of the external field is described. It has a maximum value for the resonant frequency and decreases with increasing numerically found resonance frequencies.

The processes of helium accumulation and thermal desorption for tungsten and tantalum coatings deposited on a stainless-steel substrate with an intermediate titanium layer were studied at various temperatures of the samples when irradiated with He+ ions to various fluences. The dependences of the concentration of captured helium and the form of the spectra of its thermal desorption into vacuum were found both on the fluence of He+ ions and on the temperature of the samples upon irradiation. Possible mechanisms for the accumulation and thermal desorption of helium, as well as the formation of defects in the crystal lattice of the samples, are discussed.

Published: February 2021

The redistribution of the flow of sputtered material of a target (cathode) between the collector and the target in a plane-parallel electrode system with an anomalous glow discharge is analyzed in the kinetic approximation. Sputtering is the result of bombardment of the target by gas ions accelerated in the near-cathode space charge layer and by fast neutral atoms formed as a result of resonant ion charge exchange. Sputtered atoms partially return to the target due to collisions with gas molecules. The formulas were obtained, which were confirmed in the experiment that makes it possible to correctly estimate the ratio of the sputtered material flows deposited on the collector and the target. The results of the work are used to calculate the parameters of the processes of coating deposition and ion cleaning of the target under conditions of the anomalous glow discharge.

Published: February 2021

The results of studying the spectral, integral, and resource characteristics of gas-discharge plasma radiation on multicomponent mixtures (cadmium diiodide with helium and xenon atoms) are presented. The creation of a gasdischarge plasma and the excitation of the components of the working mixture were carried out by a pulse-periodic (pulse repetition rate of 18…20 kHz, pulse duration ~ 150 ns) barrier discharge. Radiation in the visible spectrum of exciplex molecules of cadmium monoiodide, cadmium atoms, xenon was detected. The regularities in changes in the emission characteristics of the plasma are established depending on the repetition rate of the pump pulses, the component and quantitative composition of the mixtures. Research data is of interest for creating a gas-discharge source that radiates simultaneously in the violet, green, red, and infrared spectral ranges.
