Direct translation of mechanical force into changes in chemical behavior on a molecular level has important implication not only for the fundamental understanding of mechanochemical processes, but also for the development of new stimuli-responsive materials. In particular, detection of mechanical stress in polymers via non-destructive methods is important in order to prevent material failure and to study the mechanical properties of soft matter. Herein, we report that highly sensitive changes in photoluminescence intensity can be observed in response to the mechanical stretching of cross-linked polymer films when using stable, (pyridinophane)Cu-based dynamic mechanophores. Upon stretching, the luminescence intensity increases in a fast and reversible manner even at small strain (< 50%) and applied stress (< 0.1 MPa) values. Such sensitivity is unprecedented when compared to previously reported systems based on organic mechanophores. The system also allows for the detection of weak mechanical stress by spectroscopic measurements or by direct visual methods.<br>

RESUMENEl presente artículo es fruto de una investigación de largo alcance que busca generar discusión en torno a los desafíos contemporáneos del Trabajo Social en la construcción de alternativas de intervención social en contextos de diversidad sexual en Chile. La crisis de la norma heterosexual refleja una contemporaneidad marcada por la visibilidad de los grupos históricamente excluidos, reflejo de la sensibilización y cuestionamiento de una masculinidad dominante intrínsecamente exclusora e inalcanzable, como también de procesos de posicionamiento político y cultural de un colectivo presente, pero hasta hace poco invisibilizado, en nuestro país. A través de técnicas etnográficas y la incorporación del concepto de mercado como vehículo de visibilidad, el trabajo propone ideas coherentes con la construcción de una praxis transdisciplinar que responde a la nueva definición de Trabajo Social, en discusión a nivel mundial, como de los procesos de cuestionamiento y mudanza ciudadanos revitalizados en la última década.Palabras clave: Intervención social, diversidad sexual, trabajo social, desafíos. Diversidade sexual e intervenção social: reflexões a partir do Trabalho SocialRESUMOO presente artigo é o resultado de uma pesquisa de longo alcance que procura gerar discussão em relação aos desafios contemporâneos do Trabalho Social na construção de alternativas de intervenção social em contextos de diversidade sexual no Chile. A crise da norma heterossexual reflete uma contemporaneidade marcada pela visibilidade dos grupos historicamente excluídos, reflexo da conscientização e questionamento de uma masculinidade dominante intrinsecamente que exclui e que se apresenta como inatingível, bem como processos de posicionamento político e cultural de um coletivo presente, mas até recentemente invisível em nosso país.

Through ethnographic technics and theincorporation of the concept of market as a vehicle of visibility, this worksproposes ideas coherent with the construction of a cross-curricular praxisthat responds to the new definition of social work, globally discussed, as wellas the questioning processes and citizen movements during last decade.Keywords: Social intervention, sexual diversity, social work, challenges

This paper discusses the method used to identify the process involving fatigue cracking of samples on the basis of selected vibration signal characteristics. Acceleration of vibrations has been chosen as a diagnostic signal in the analysis of sample cross section. Signal characteristics in form of change in vibration amplitudes and corresponding changes in FFT spectrum have been indicated for the acceleration. The tests were performed on a designed setup, where destruction process was caused by the force of inertia of the sample. Based on the conducted tests, it was found that the demonstrated sample structure change identification method may be applied to identify the technical condition of the structure in the aspect of loss of its continuity and its properties (e.g.: mechanical and fatigue cracks). The vibration analysis results have been verified by penetration and visual methods, using a scanning electron microscope.

Introduction. Under the influence of globalization and regionalization; the world economic development is becoming more dynamic but contradictory at the same time; creating new challenges and threats for both individual countries and entire regions. This exacerbates the urgency of forming flexible systems of security cooperation and finding solutions to regional and global security problems. Purpose. The purpose of the paper is to systematize research on regional and global security governance and a review of the balance of geopolitical forces in Europe. Methods. The research was carried out using the following methods: analysis and synthesis – to characterize the modern mainstream of theoretical intelligence in the field of regional security; comparative analysis – to compare the structures of regional security management in different parts of the world; deductions and inductions – to form a conceptual model of global governance; tabular and visual methods – for visual presentation of the material. Results. The paper considers theoretical approaches to the interpretation of regional security. It is noted that regional security governance is a set of institutions and activities at three levels: global; regional and national. A nomenclature of different types of regional security governance structures is presented; which includes a regional balance of power and ad hoc (informal) alliances; regional coherence; regional cooperative security; regional collective defense; regional collective security; pluralistic security community. It has been recognized that regional security management is provided not only by highly specialized or formal structures; but also by multi-purpose regional organizations; which initially pursued a combination of economic and political goals with growing security targets. Conceptual options for regional security governance at the global and regional levels are systematized. Based on the analysis of the mechanisms of global management; own vision of the relationship between the subjects of global governance processes is presented. Discussion. The crisis of recent decades has shown that no single group of global governance actors can act effectively to minimize global risks; which are both a challenge for business leaders and politicians in any country. That is why it is undeniable that global issues require global governance (especially in the field of security); the main goal of which should be to ensure global stability and sustainable development.

Humankind is becoming increasingly image based. Visual culture is everywhere: it surrounds us all with still and moving images. Based on this pictorial change, working with the visual in education has the potential for engaging students in a process of self-reflection in an effort to change ways of thinking and behavior, aiming to consolidate concepts taught in classes. Nevertheless, there are key elements to consider as a set of methodologies and practices. The aim of this study is to explore multiple ways of working with the visual, within educational environments, specifically in classes taught in the second and third year of a degree in Tourism. Two examples of visual methodologies were considered for this study. An image-based exercise through the use of tourism cartoons as visual stimuli to evoke opinions and incite thoughts was fully implemented. Analysis was undertaken and the results are presented. A reflexive photography method is also proposed as another example for a visual-based exercise. The results from the cartoons exercise demonstrate that knowledge is continuously derived from the experience of the learner. The student's impressions and full comprehension of the concepts taught in a particular subject were achieved with this exercise.
