The Methods of Information Management in the Space of the Current Scientific Discourse: Recommendations for Public Sector Organisations
Authors: Baran Michał
Published: October 2024

Objectives: The information age constantly poses new challenges for management specialists. Such a circumstance encourages to creative considerations on how to overcome these challenges. The dynamics of changes taking place in the organisational environment and the response to them, which is formulated by the scientific community, is then an interesting subject of research. The author adopts the thesis that it is possible to identify certain common elements of the ongoing discourse, which determine its current character, adequate to the challenges of the present day. The presented analysis includes a study of examples of invoking information management methods in publications from recent years.
Research Design & Methods: The qualitative text analysis – especially one based on the method of binary oppositions – was used in the considerations. The use of this method makes it possible to indicate examples of common denominators connecting the publications that were the subject of the research.
Findings: As the result of the conducted research, the dimension of directing the discourse to the context of using the latest IT technologies to improve internal processes and, on the other hand, to increase the scope of interorganisational integration was revealed. Another dimension of the discourse turned out to be the reference to information management methods in the context of using IT to change the role and importance of the human factor, but also to autonomise and automate the production system.
Implications / Recommendations: Based on the conducted analyses, recommendations were formulated that will make it easier for public sector organisations to implement their missions within the context of identified dimensions. However, it is necessary to implement changes consistent with the detected trends shaping the interorganisational information exchange network.
Contribution / Value Added: It was found out that in the face of the changing level of complexity of the environment and the dynamically growing level of inter-organisational integration, the public sector must ensure its ability to engage in ongoing processes. This requires the introduction of appropriate system and organisational solutions as well as the development of analytical competences, taking into account the potential of artificial intelligence and other advanced information technologies.

TERRITORIAL PUBLIC SELF-MANAGEMENT (TPSM) AS A MECHANISM TO DEVELOP THE TERRITORY IN MODERN CONDITIONS
Authors:   Perm State University, Mukhin Mikhail A. , Urasova Anna A. ,   Perm State University
Published: October 2024

The article deals with problems occurred in implementing territorial public self-government in the regions of Russia in modern conditions. The basis of the study was to consider the main forms of interaction between the TPSM and the local authorities, the choice of which depends both on the peculiarities of the subject’s development and on the complexity of the mechanisms used to implement this interaction. Methodologically the work was grounded on the comparative analysis of the organization and development of the TPSM Institute at the regional level, which allowed the authors to formulate a conclusion with regard to systemic problems in the TPSM organization, the advantages in cooperation with state and municipal authorities. Here we state the absence of one person responsible for the activities of the TPSM body of state power, the lack of reliable statistical data on the TPSM in the Russian Federation, making it impossible to determine the level of development of this direct democracy form, and as a result to develop a state policy in this sphere. In addition, a significant difficulty in the implementation of TPSM is the lack of a unified approach to the processes of the organization and development of TPSM, which leads to a variety of forms of TPSM organization and development in the regions and municipalities.

Authors:   Legislative Assembly of Perm Krai, Braun Elena A.
Published: October 2024

Remote work was given some regulatory grounds quite recently, but now we can say that its scope is quite extensive. The draft contract for freelance work is very modern and sets a new breakthrough in the development of labor legislation. Today the legislator has not defined criteria that restrict the use of remote work in a partic-ular field of employment. Thus, we can assume that this draft contract is applicable for work in state bodies. Public authorities under the article on state power and other state bodies with the authority and the legislature, for example, electoral Commis-sion, audit chamber of the Russian Federation, etc. The purpose of this article is to define the conditions and limits of the use of telework in government agencies, to develop possible recommendations on the use of remote labor relations in state bodies.The review of the regulatory framework in reforming the approaches to public administration and scientific debate that allows one to confirm or refute the thesis about the possibility of teleworking in the government is the main purpose of this article.

To solve the management tasks related to further development of enterprises and to provide them with necessary assistance and support, to improve their activi-ties one should have information on the current distribution structure of enterprises depending on the number of employees. The aim of the study is to analyze regulari-ties and trends in characterizing the distribution of different numbers of workers in the enterprises and workers there. We use official statistical information as input data. The research was based on the analysis of weights of enterprises with a certain number of employees in the total number of enterprises and weights of workers employed in such enterprises in the total number of employees. It has been shown that high quality approximation of the original data provides power and exponential monotonically decreasing function respectively. It was found that the enterprises with 5 employees and less dominate among the enterprises employing up to 250 people. It is established that from 2010 to 2013 the proportion of these enterprises has increased.
Excluding Life and Insurance Benefits from Insolvent Estates: A Comparative Study of South Africa, England and Wales, and the United States of America
Authors: Mabe Zingapi , Mbiriri Edith
Published: October 2024

In South Africa, two principles apply to the exclusion of certain assets from an insolvent estate. First is the common-law principle that even the desperate insolvent is entitled to the basic necessities of life. Hence his entitlement to keep certain assets and to protect assets belonging to third parties. Secondly, the "creditor advantage" principle requires the trustee of the insolvent estate to collect assets to benefit the creditors of the estate. One of the assets excluded from the insolvent estate is the life and disability insurance policy benefits of the insolvent. These benefits are excluded, however, only if the beneficiary is the insolvent and the exclusion will not apply where the beneficiary is a third party such as a solvent spouse. However, section 21 of the Insolvency Act 24 of 1936 vests the assets of the solvent spouse in the trustee of the insolvent estate upon the latter's sequestration. This vesting is out of sync with the principle aimed at protecting assets belonging to third parties. In England and Wales a trust is created to protect the insurance policy benefits of a spouse or child of the bankrupt but does not extend to any other third party. In the United States of America the proceeds of a life insurance policy benefit will form part of the estate if the bankrupt owned it before the bankruptcy began or if the debtor acquired or became entitled to it within 180 days after the filing date. Where the debtor nominated a third party as the beneficiary of an unmatured policy, the power of appointment becomes part of the estate of the debtor. As the nominated third party acquires only an inchoate expectation, the third party's expectation of that unmatured life insurance policy benefit forms part of the bankrupt estate. This paper compares the treatment of life and disability insurance benefits in insolvent estates in South Africa with the position in England and Wales and the United States of America to establish whether there are lessons to be learnt which may assist in modelling an insolvency law process for South Africa which will consider the affected members of society.

Published: October 2024

The structural and magnetic properties of iron-cobalt alloys (FeCoV) were compared to those of electrical steel alloys. The latter are widely used for the ferromagnetic cores of electric motors. However, the as-cast and rolled FeCoV alloys, which were analysed, showed enhanced magnetic properties compared to electrical steel alloys. Moreover, since they can be cast directly into the final shape of the rotor’s main structure (excluding the pole shoes, which must be laminated) for a wound-rotor synchronous electric motor, the production becomes more cost-effective and energy-efficient. In addition, the performance of the electric motor is improved in terms of mechanical output power and energy efficiency.
Shifting Trade Ties of the United States and China with Their Partner Countries: Changes Over the Five Years of Turbulence
Authors:   CMASF, Gnidchenko Andrey ,   IEF RAS,   HSE University
Published: October 2024

In this paper, we track the shifts in economic ties of the United States and China with partner countries in the context of commodity and service trade. We propose the grouping of major partner countries and regions: China, the US, North America (excluding the US), Europe, ASEAN, Chip 4 alliance countries (South Korea, Japan, Taiwan), India, and other countries. The dynamics of trade ties is broken down into three stages: active phase of the US-China trade war (July 2018 – January 2020); post-COVID recovery of the global economy (February 2020 – January 2022); geopolitical turbulence (February 2022 – present). Regarding commodity trade, we document the changes in trade ties of the US and China with key groups of partner countries during each stage; apart, we examine the US trade in services with partner countries. A steady decline in commodity trade between the US and China was observed only during the third stage, while the drop during the trade war had turned out to be temporary. Trade in services between the US and China started to fall a bit earlier, during the second stage. At the third stage, the US commodity trade deficit with China declines in parallel with an increase in the commodity trade deficit with ASEAN, the Chip 4 alliance, and North America (partly due to reexported Chinese goods). In 2020, China has reached a record share in global commodity exports (about 16%) and continues to hold strong. We propose the short list of countries and regions that may have the strong impact on growth and restructuring of world trade in the long term, in particular: China, ASEAN, North America, Russia, and India. The list relies on the following facts: retention of China’s extraordinary position in world trade even under the increasing pressure from the West; active integration and exceptional trade connectivity of ASEAN countries; significant efforts by the US to reintegrate North America and reshoring high-tech production back to the continent; Russia’s very high interest in developing cooperation within BRICS and decentralizing international payments; the rise of India as a major sales market.
EU Sanctions Policy toward Russia after February 2022: Major Transformation Trends
Authors:   MGIMO University, Timofeev Ivan , Chupriyanova Polina ,   Russian International Affairs Council
Published: October 2024

The EU sanctions policy against Russia has been under transition since February 2022. The dramatic increase of Russian persons and sectors of economy under sanctions indicates quantitative changes of the EU's approach. On the other hand, these transformations are of qualitative nature. Qualitative changes include the revision of the EU's position on the use of secondary restrictions, as well as visible shifts in sanctions’ enforcement. At the same time, these transformations are poorly reflected in the academic literature. The purpose of the article is to fill in these gaps, as well as to address the research questions on the key changes in the EU's approach to implementing sanctions policy against Russia after February 2022 and the dynamics and features of these changes. RIAC databases on sanctions and analysis of the EU normative documents on the policy of sanctions are the main tools of empirical observations.
Lenguaje y grupos sociales. Algunas observaciones sobre el programa intencional en ontología social
Authors:   Universidad Nacional de Mar del Plata, Paolicchi Leandro
Published: October 2024

En el siguiente trabajo se examina la explicación de Raimo Tuomela acerca de la aparición de los hechos sociales básicos. En esa propuesta, los componentes elementales de una ontología social se deben a la “intencionalidad colectiva” compartida por diferentes actores. Si bien Tuomela hace alusión al lenguaje presente en algunas formas de intencionalidad, su reconstrucción está orientada a otras formas de generar hechos sociales que supuestamente no lo incluirían o serían más básicas que las generadas por esa praxis. En este escrito se sostendrá, por el contrario, que no es posible eludir al lenguaje como principal mecanismo de generación de fenómenos elementales de la socialidad en ninguna instancia. Una vez que el lenguaje ocupa su lugar como principal instrumento de coordinación de la acción, creador de grupos sociales y desarrollo de una ontología social, muchas de las distinciones del programa intencionalista pierden relevancia desde un punto de vista ontológico.

The theoretical investigation of the interaction of elastic planar harmonic waves in a material whose nonlinear properties are described by the Murnaghan elastic potential is presented. A review of the methods for analytical study of the wave process is provided. The methodology for studying transverse and longitudinal waves is described. Using the perturbation method for transverse waves, results are presented for the simultaneous propagation of two types of waves: vertically and horizontally polarized. The corresponding equations are written, and the distortion of the respective wave profiles is analyzed. It has been established that because of the nonlinear wave interaction, the transverse waves gradually transform into their third harmonics. With different initial intensities of waves of different polarization, energy is transferred from the powerful wave to the weaker wave. Numerical studies were conducted using values of effective constants for a range of nanocomposite materials. For longitudinal waves, the simultaneous propagation of waves with separate consideration of quadratic and cubic nonlinearity was investigated. Various cases of harmonic wave interaction were studied based on cubic equations of motion. The method of slowly varying amplitudes was sequentially used. The obtained equations, the first integrals of these equations, and the conservation law for four interacting waves are analyzed. Truncated and full evolutionary equations were obtained, and the Manley-Rowe relations were recorded. This research method assumes weak variability of the amplitudes and phases of waves over one period of the oscillatory process. The field of application of such wave research includes several problems in nonlinear optics and plasma physics. Considering cubic nonlinearity is also necessary for the study of internal and surface waves in a fluid. Similarly to how wave triplets can form in quadratically nonlinear media through three-wave interaction, four-wave interaction occurs in cubically nonlinear media, with the formation of wave quadruplets under certain conditions.

The problem of creep of a solid-fuel rocket engine under the action of its own weight when stored in a vertical position is considered. The purpose of the work is to study the stress-strain state of the engine, to determine the areas of localization of stresses and strains, in particular, radial tensile and tangential stresses at the cylinder-shell interface. The engine is modeled as a hollow cylinder with a circular cross-section made of a linear isotropic thermo-rheologically simple viscoelastic material supported on the lateral surface by a three-layer elastic shell. The relaxation function of the cylinder material under uniaxial tension is represented by the sum of exponents, and the volumetric deformation is assumed to be elastic. The problem is solved using the Schapery approach, which reduces the viscoelastic problem to an elastic problem with time-varying moduli. The problem transformed in this way is solved by the finite element method. A quadrilateral isoparametric element is used. The distributions of current and time-steady-state stresses and creep strains at certain points in the engine volume are investigated. It is established that the maximum stresses in the cylinder are localized in the vicinity of the corner points of the cylinder-shell boundary, where a singularity of stresses occurs in the linear formulation. In the same areas, the maximum values of tensile radial and tangential stresses are reached, which are dangerous from the point of view of charge detachment from the casing. Significant values of axial compressive stress occur in the lower support part of the cladding. The largest are the shear deformations of the cylinder along the contact boundary with the cladding. The creep curves at the cylinder points at room temperature are plotted. The estimation of the characteristic creep settling time is given.

In the modern inertial sensors based on the bulk acoustic waves propagation, the change of the polari­za­ti­on vector through a certain finite length of the waveguide, is proposed to determine the angular velocity. It is caused by Coriolis dispersion due to the action of the inertial forces of rotational motion. Among the important issues of calculation of reflected and refracted waves in rotational motion, one can mention joined wave­gui­des, reflec­tion from a non-orthogonal boundary, etc. So, the problem of the incidence and ref­lec­tion of Coriolis- dispersed harmonic waves on the surface of an elastic half-space at an arbitrary angle of pro­pagation plays the key role. Research in this regard besides the study of the effect of Coriolis dis­per­si­on in reflected waves, includes also piezoelectric and thermal material properties of waveguides. In the ma­thematical modelling the authors of [6] consider the general solutions for mechanical and electrical quan­tities in the some way as in the non-rotating classical case of elastodynamics and thermo­electro­elasticity. In our opinion, the general solutions for incident and reflected waves should be built on the basis of fun­da­­mental solutions for quasi-longitudinal and quasi-transverse waves, propagating in the unbounded ro­ta­ting medium. In the statement of the problem, it should be assumed in advance, that the incident and ref­lec­ted waves are formed by two coupled components of displacements, that is, such waves have elliptical polarization.
Approximate averaged bounded synthesis for a parabolic process with two switching points

Published: October 2024

In this paper we analyze the problem of the optimal bounded control with semi-definite quality criterion for parabolic process with rapidly oscillating coefficients on finite time interval. The case when optimal control goes out both on lower, and on upper restriction, that is has two switch-points is considered. Our aim is to build a synthesized control which is practically preferable to program one. But after Fourier method application such a control will contain coefficients which are expressed by series and, in addition, it irregularly depends on small parameter ε. Thus, for practical application it is natural to restrict infinite series by finite sums and to get rid of dependence on a small parameter using average procedure. So, besides the law of optimal synthesis also approximate averaged feedback control, which provides control system behavior that is close to optimal one and thus has a series of advantages from the practical application point of view, is proposed and proved. The efficiency of approximate averaged control construction procedure consisted of cutting to finite sums of series in optimal control and replacing of Fourier coefficients nonregular depended on small parameter by corresponding average values is illustrated by an example of controlled system for parabolic process. We compare the properties of the averaged control and the sequence of optimal controls calculated at the different values of the small parameter. For comparison, we use the switching points of optimal control and averaged control, deviation between optimal control and averaged control, the difference in the values of the quality criterion on optimal control and averaged control. In considered example the precision of quality criteria value on approximate control has ε-order and for sufficiently small ε the precision is one order better then ε.

Published: October 2024

This study focuses on investigating stimulated Raman scattering under self-focusing conditions and the impact of other parameters on its efficacy. Contrary to expectations, the efficiency of stimulated Raman scattering could discontinue to increase, and may rather start to decline when the input radiation power grows, because of the "absolute saturation" effect. The paper investigates the influence of this effect under self-focusing conditions using the example of a ruby laser in toluene. Calculations are given in order to characterize the indicated phenomenon based on power and Stokes component. The approaches for mitigating the impact of the "absolute saturation" effect on the process by increasing the initial radius of the incoming laser beam are being examined. A software product was developed using the Wolfram Mathematica program to enable calculations for each unique scenario. This software helps in selecting the settings to achieve the optimal parameters to ensure the highest efficiency of Raman scattering.
What Gender Theory Does Russian Social Psychology Need
Authors: Radina N.K.
Published: October 2024

Objective. The article problematizes the theoretical field of gender studies and the concept of “gender”, which are currently vulnerable in the socio-political context. The aim of the article is to determine the range of theories of Russian psychologists capable of solving topical issues in the field of gender social psychology outside of a politically conflicting discourse.
Background. According to political theory, psychological knowledge can become a guide for political practice, this area of political science is called biopolitics. The constructivist theoretical field of gender studies belongs to the field of biopolitics; in Western gender theory, the deconstruction of gender is allowed not only as a social phenomenon, but also as a change in biological sex. Moreover, the possibility of deconstructing gender and sex is currently determined by political practice, not by psychological or psychiatric indications. The use of Western gender theory and the concept of “gender” in political conflicts pushes Russian social psychology to search for a theory based on the concepts of Russian psychologists focused on the analysis of the socio-psychological reality of gender relations.
Results. The article emphasizes the impossibility of the reverse movement of science and the choice of the gender-role approach as outdated, not responding to the needs of modernity. Three theories are called productive and adequate to modern problems: the cultural-historical theory of L.S. Vygotsky, the subject-activity approach of S.L. Rubinstein, the theory of relations by V.N. Myasishchev. The concept of gender relations by I.S. Kletsina, one of the most popular modern concepts of gender in Russian psychology. Conclusions. Gender psychology is a new branch of social psychology, which turned out to be vulnerable to political initiatives in a period of socio-political instability. The search for new theoretical constructs and the educational activity of psychologists in the biopolitical field will help gender psychology overcome the crisis period.

Objective. To analyze the contribution of the most immediate contextual influences (child-parent emotional communications) to the resilience of the adult family (using the samples from Belarus and Russia). Background. Understanding the role of emotional dysfunctions in parent-child relationships in the context of Russian and Belarusian cultures helps to identify the conditions for the resilience of a future adult family, which can become the basis for social family policy at the state level and improvement of the practice of psychological assistance to families.
Study design. The study was conducted online using the snowball method. Multiple regression analysis was conducted to determine the impact of dysfunction in parental families, intensity of the negative events, age of respondents and number of children on family resilience. Children's experiences of adults are illustrated by the results of projective technique.
Participants. The study involved 853 respondents (595 people from the Russian Federation, 258 from the Republic of Belarus) aged from 18 to 77 years (average age 36 ± 12 years, median = 36 years), 90,5% female.
Measurements. Family resilience was assessed using Gusarova’s et al. “Family Resilience Assessment Scale” (FRAS-RII). Dysfunctions in parental families were determined according to Kholmogorova’s et al. “Family Emotional Communications” and the projective technique of Odintsova et al. “Space of Trees and Light.” The intensity of negative events in families was assessed on a scale from 1 to 10.
Results. Dysfunctions in parental families make a significant contribution to the resilience of the future adult family (up to 20% of explained variance). Family perfectionism has a positive effect, and the elimination of emotions has a negative impact on the resilience of adult families in the context of two cultures. In Russian families of origin there is over-involvement, and in Belarusian families criticism negatively affects the resilience of respondent’s families.
Conclusions. The critical atmosphere in parental families, the high intensity of adverse events in Belarusian families, and overprotection in the parental families of Russians contribute to a decrease in families’ resilience. The presence and number of children in a family contributes to the family resilience in both countries. Culture and traditions are a solid basis for the majority of Russians and Belarusians.
Perception of Parental Attitudes and General Academic Achievement of High School Students: a Russian-Kyrgyz Study
Authors: Tikhomirova T.N. , Malykh S.B.
Published: October 2024

Objective. Cross-cultural analysis of the perception of parental attitudes and its influence on the general academic performance of high school students from Russia and Kyrgyzstan.
Background. The characteristics of parental attitudes are closely related not only to the child’s educational success during life in the family, but also to educational achievements in the future. At the same time, the sociocultural specifics of parent-child relationships, through the perception of a growing child, can change the direction and magnitude of such associations.
Study design. The characteristics of the relationship between mothers and fathers – emotional acceptance and overprotection – by high school students from two countries differing in socio-economic status are analyzed. A cross-cultural analysis of the structure of associations between the characteristics of the perception of parental attitudes and academic performance is carried out.
Participants. The study analyzed data from 528 students in grades 10–11 from Russia and Kyrgyzstan. Russian sample: 230 people (M = 17,31; SD = 0,7), 58,1% girls. Kyrgyz sample: 298 people (M = 17,21; SD = 0,7), 67,6% girls.
Measurements. Russian-language version of the questionnaire “Parental Bonding Instrument” (T.N. Tikhomirova, D.A. Gaysina, S.B. Malykh, 2021).
Results. At high school age, the perception of parental attitude has a culture-specific conditioning, most clearly expressed in the perception of emotional acceptance by the mother and the overprotective attitude of the father.
Conclusions. Given the existence of a universal model of the influence of parental attitudes on the general academic performance of high school students, cross-cultural specificity of functional associations within the model is observed, which is more characteristic of the perception of the attitudes of fathers rather than mothers.
Effects of Enzyme and Probiotic on the Growth Performance of Broiler Chickens: A Meta-Analysis
Authors: Sugiharto Sugiharto , Setiaji Asep , Adli Danung Nur , Sholikin Muhamad Misbakhul
Published: October 2024

A meta-analysis was conducted to determine the effects of enzyme and probiotic on the growth performance of broiler chickens. A collection of publications covering the years from 2009 to 2021 was compiled using several keywords, such as enzyme, growth performance, and probiotic. A total of 136 comparisons from 19 in vivo investigations were used to create the final dataset. The data were analyzed using the OpenMEE software, considering the feed additives (enzymes and probiotics) as fixed effects and individual studies as random effects. The result showed an insignificant difference (P0.05) between enzymes and probiotics in terms of improving the body weight gain, feed intake, and feed conversion ratio (FCR) of broilers. In conclusion, both probiotics and enzymes improved broiler performances, such as body weight gain, feed intake and FCR. According to the meta-analysis, the ability of enzymes and probiotics to affect broiler performances was equal.
Lógicas de blanquitud/colonialidad/modernidad en la Política Exterior Feminista del Reino de España
Authors: Carrazco López Eveling
Published: October 2024

El presente artículo plantea un análisis descolonial y antirracista de la propuesta de una cooperación feminista del Reino de España contenida en varios documentos, como el de la Política Exterior Feminista (MAEC, 2021). El artículo analiza hasta qué punto esa perspectiva feminista es “transformadora” de las realidades y las desigualdades de género de los países receptores de la cooperación y de la acción exterior. Para hacer esto me apoyaré en revisión documental, en el seguimiento de espacios donde esta política se ha discutido (de algunos de los cuales he sido parte) y en los análisis de los feminismos descoloniales, anticoloniales, antirracistas y antisistémicos, particularmente de Abya Yala.

Authors: Kappenberg Claudia
Published: October 2024

A review of three films by Siobhan Davies, All This Can Happen (2012), The Running Tongue (2015) and Transparent (2022), and discussion of her shift from live performance to working with the still image and film. Davies’s work is described as a kind of archaeological practice with long-form choreographic projects which are underpinned by a ‘poetics of responsibility’. Offering a reservoir of images and relations and allowing for innumerable different viewing experiences, they invite audiences to see for themselves and to grasp what embodied liveness is within each instant.
Drawn to the light: Cinematic and Performative Ecologies in Stan Brakhage's Mothlight (1963) and Eiko Otake's Night with Moths (2019)
Authors: Wasserman Tina
Published: October 2024

The purpose of this essay is to explore the evocative use of moths within cinematic and performative contexts. To do so, two moving image works were chosen, each framed within in a comparative context to the other: the first, the historic and iconic masterwork of avant-garde cinema by the legendary filmmaker Stan Brakhage titled Mothlight (1963), and the second, a contemporary performance video titled Night with Moths (2019) by the interdisciplinary movement-based artist, Eiko Otake. With their attraction to light, along with their fluttering, nocturnal flights, moths seem to have a strong kinship with not only the moving images of cinema, but also with the movement focus of dance and performance. Indeed, the very presence of moths in both moving image works, invites us to witness compelling cinematic and performative collaborations that move across species and ecologies.
Odissi on Screen: A Meditation on Regional Television
Authors: Sarkar Kaustavi
Published: October 2024

This article aims to interrogate the role of the television screen in creating, re-creating, disseminating, and deconstructing the dancing body. It presents a study of the contemporary landscape of odissi dance, a nationally recognized Indian traditional art form from the eastern Indian state of Odisha, through its on-screen representation. As an odissi soloist, I register, analyze, and interpret screenic data, mainly televised interviews of dancers, live telecasts of dance festivals in Odisha, and performances recorded for the camera in the studios. I focus on content primarily broadcast on the state-owned satellite channel broadcasting in Odia, the official language in Odisha. My position is of a Sahrdaya, an observer tutored in the codes and conventions of the art form and critically responsive to the structure of emotion in the presentation. I locate the dancing body across discursive, disseminative, and choreographic renditions. This subjective positioning, I argue, democratizes the expressive ethos of odissi embodiment. Commenting on the contemporary curation of the dancing body by the state network, this essay brings larger questions around the representation of gender, sexuality, caste, and regionalism on the television screen.
¿Hacia dónde va el sistema de la seguridad social?: El mantenimiento del poder adquisitivo de los pensionistas, las expectativas en la prolongación de la vida laboral, las mejoras en el subsidio para desempleados mayores de 52 años, la equiparación entre regímenes y la esperada mejora de las prestaciones familiares

En los últimos 6 meses se han sucedido modificaciones en el ámbito de la Seguridad Social que reflejan las tendencias en la materia que quizás vayan a marcar también el camino de las reformas futuras. Se suspende la utilización del índice de revaloración de las pensiones con el fin de garantizar el mantenimiento del poder adquisitivo; se amplían los supuestos de compatibilidad de jubilación y actividad profesional, buscando la prolongación de la vida laboral, que chocan con otras modificaciones como la admisión de cláusulas de jubilación forzosa en convenios colectivos, que parece tener el fin opuesto; se amplía la protección del subsidio por desempleo a los mayores de 52 años; y se da un paso más en la convergencia de la protección social de los regímenes de la Seguridad Social.
