mHealth Interventions to Reduce Physical Inactivity and Sedentary Behavior in Children and Adolescents: Systematic Review and Meta-analysis of Randomized Controlled Trials
Authors: Baumann Hannes , Fiedler Janis , Wunsch Kathrin , Woll Alexander , Wollesen Bettina
Published: March 2022

Background

Children and adolescents increasingly do not meet physical activity (PA) recommendations. Hence, insufficient PA (IPA) and sedentary behavior (SB) among children and adolescents are relevant behavior change domains for using individualized mobile health (mHealth) interventions.

Objective

This review and meta-analysis investigated the effectiveness of mHealth interventions on IPA and SB, with a special focus on the age and level of individualization.

Methods

PubMed, Scopus, Web of Science, SPORTDiscus, and Cochrane Library were searched for randomized controlled trials published between January 2000 and March 2021. mHealth interventions for primary prevention in children and adolescents addressing behavior change related to IPA and SB were included. Included studies were compared for content characteristics and methodological quality and summarized narratively. In addition, a meta-analysis with a subsequent exploratory meta-regression examining the moderating effects of age and individualization on overall effectiveness was performed.

Results

On the basis of the inclusion criteria, 1.3% (11/828) of the preliminary identified studies were included in the qualitative synthesis, and 1.2% (10/828) were included in the meta-analysis. Trials included a total of 1515 participants (mean age (11.69, SD 0.788 years; 65% male and 35% female) self-reported (3/11, 27%) or device-measured (8/11, 73%) health data on the duration of SB and IPA for an average of 9.3 (SD 5.6) weeks. Studies with high levels of individualization significantly decreased insufficient PA levels (Cohen d=0.33; 95% CI 0.08-0.58; Z=2.55; P=.01), whereas those with low levels of individualization (Cohen d=−0.06; 95% CI −0.32 to 0.20; Z=0.48; P=.63) or targeting SB (Cohen d=−0.11; 95% CI −0.01 to 0.23; Z=1.73; P=.08) indicated no overall significant effect. The heterogeneity of the studies was moderate to low, and significant subgroup differences were found between trials with high and low levels of individualization (χ21=4.0; P=.04; I2=75.2%). Age as a moderator variable showed a small effect; however, the results were not significant, which might have been because of being underpowered.

Conclusions

Evidence suggests that mHealth interventions for children and adolescents can foster moderate reductions in IPA but not SB. Moreover, individualized mHealth interventions to reduce IPA seem to be more effective for adolescents than for children. Although, to date, only a few mHealth studies have addressed inactive and sedentary young people, and their quality of evidence is moderate, these findings indicate the relevance of individualization on the one hand and the difficulties in reducing SB using mHealth interventions on the other.

Comparison of the Mental Burden on Nursing Care Providers With and Without Mat-Type Sleep State Sensors at a Nursing Home in Tokyo, Japan: Quasi-Experimental Study (Preprint)
Authors: Itoh Sakiko , Tan Hwee-Pink , Kudo Kenichi , Ogata Yasuko
Published: March 2022

BACKGROUND

Increasing need for nursing care has led to the increased burden on formal caregivers, with those in nursing homes having to deal with exhausting labor. Although research activities on the use of internet of things devices to support nursing care for older adults exist, there is limited evidence on the effectiveness of these interventions among formal caregivers in nursing homes.

OBJECTIVE

This study aims to investigate whether mat-type sleep state sensors for supporting nursing care can reduce the mental burden of formal caregivers in a nursing home.

METHODS

This was a quasi-experimental study at a nursing home in Tokyo, Japan. The study participants were formal caregivers who cared for residents in private rooms on the fourth and fifth floors of the nursing home. In the intervention group, formal caregivers took care of residents who used sleep state sensors on the fourth floor of the nursing home. The sleep state sensors were mat types and designed to detect body motion such as the frequency of toss and turning and to measure heartbeat and respiration. One sensor was placed on a bed in a private room. When body motion is detected, the information is instantly displayed on a monitor at a staff station. In addition, the mental condition of the formal caregivers was measured using a validated self-reported outcome measure—the Profile of Mood States (POMS), Short-Form, 2nd edition. Formal caregivers in both groups received the POMS at baseline, midpoint (week 4), and endpoint (week 8) to identify changes in these domains. The primary outcome was the difference in total mood disturbance (TMD) of the POMS at baseline and week 8.

RESULTS

Of the 22 eligible formal caregivers, 12 (intervention group) utilized sleep state sensors for 8 weeks. The remaining 10 formal caregivers (control group) provided nursing care as usual. As for the primary outcome of the difference between TMD at baseline and week 8, TMD in the intervention group improved by –3.67 versus 4.70 in the control group, resulting in a mean difference of –8.37 (95% CI –32.02 to 15.29; P=.48) in favor of the intervention.

CONCLUSIONS

The present 8-week study showed that sleep state sensing for elderly residents might not be associated with reduced mental burdens on formal caregivers in nursing homes.

Published: March 2022

BACKGROUND

A large proportion of the prison population experiences substance use disorders (SUDs), which are associated with poor physical and mental health, social marginalization, and economic disadvantage. Despite the global situation characterized by the incarceration of large numbers of people with SUD and the health problems associated with SUD, people in prison are underrepresented in public health research.

OBJECTIVE

The overall objective of the PriSUD (Diagnosing and Treating Substance Use Disorders in Prison)-Nordic project is to develop new knowledge that will contribute to better mental and physical health, improved quality of life, and better life expectancies among people with SUD in prison.

METHODS

PriSUD-Nordic is based on a multidisciplinary mixed method approach, including the methodological perspectives of both quantitative and qualitative methods. The qualitative part includes ethnographic fieldwork and semistructured interviews. The quantitative part is a registry-based cohort study including national registry data from Norway, Denmark, and Sweden. The national prison cohorts will comprise approximately 500,000 individuals and include all people imprisoned in Norway, Sweden, and Demark during the period from 2000 to 2019. The project will investigate the prison population during three different time periods: before imprisonment, during imprisonment, and after release.

RESULTS

PriSUD-Nordic was funded by The Research Council of Norway in December 2019, and funding started in 2020. Data collection is ongoing and will be completed in the first quarter of 2022. Data will be analyzed in spring 2022 and the results will be disseminated in 2022-2023. The PriSUD-Nordic project has formal ethical approval related to all work packages.

CONCLUSIONS

PriSUD-Nordic will be the first research project to investigate the epidemiology and the lived experiences of people with SUD in the Nordic prison population. Successful research in this field will have the potential to identify significant areas of benefit and will have important implications for ongoing policy related to interventions for SUD in the prison population.

A Cognitive Behaviour Therapy Chatbot (Otis) for Health Anxiety Management: Pilot Study (Preprint)
Authors: Goonesekera Yenushka , Donkin Liesje
Published: March 2022

BACKGROUND

An increase in health anxiety was observed during the COVID-19 pandemic. However, due to physical distancing restrictions and a strained mental health system, people were unable to access support to manage health anxiety.

OBJECTIVE

The aim of this study was to investigate the feasibility, acceptability, engagement and effectiveness of a cognitive behaviour therapy-based chatbot (Otis) as an early health anxiety management intervention for adults in New Zealand.

METHODS

Users were asked to complete a 14-day programme run by Otis, a primarily decision-tree based chatbot on Facebook Messenger. Health anxiety, general anxiety, intolerance of uncertainty, personal wellbeing and quality of life were measured pre-intervention, post-intervention, and at a 12-week follow-up. Pearson’s correlations were conducted to investigate the associated changes in the outcomes over time. Semi-structured interviews and written responses in the self-report questionnaires and Facebook Messenger were thematically analysed.

RESULTS

29 participants completed the trial by providing outcomes measures at both post-intervention and follow-up. Although an average decrease in health anxiety did not reach significance at post-intervention (P=.55) or follow-up (P =.08), qualitative analysis demonstrated that participants perceived benefiting from the intervention. Significant improvement in general anxiety, personal wellbeing, and quality of life was associated with the use of Otis at post-intervention and follow-up. Anthropomorphism, Otis’ appearance and delivery of content facilitated the use of Otis. Technical difficulties and high performance and effort expectancy were in contrast, barriers to acceptance and engagement of Otis.

CONCLUSIONS

Otis may be a feasible, acceptable, and engaging means of delivering CBT to improve anxiety management, quality of life and personal wellbeing but not a significant reduction in health anxiety.

Published: March 2022

Background and objectives

Sodium-glucose transporter 2 (SGLT2) inhibitor–induced uric acid lowering may contribute to kidney-protective effects of the drug class in people with type 2 diabetes. This study investigates mechanisms of plasma uric acid lowering by SGLT2 inhibitors in people with type 2 diabetes with a focus on urate transporter 1.

Design, setting, participants, & measurements

We conducted an analysis of two randomized clinical trials. First, in the Renoprotective Effects of Dapagliflozin in Type 2 Diabetes study, 44 people with type 2 diabetes were randomized to dapagliflozin or gliclazide for 12 weeks. Plasma uric acid, fractional uric acid excretion, and hemodynamic kidney function were measured in the fasted state and during clamped euglycemia or hyperglycemia. Second, in the Uric Acid Excretion study, ten people with type 2 diabetes received 1 week of empagliflozin, urate transporter 1 blocker benzbromarone, or their combination in a crossover design, and effects on plasma uric acid, fractional uric acid excretion, and 24-hour uric acid excretion were measured.

Results

In the Renoprotective Effects of Dapagliflozin in Type 2 Diabetes study, compared with the fasted state (5.3±1.1 mg/dl), acute hyperinsulinemia and hyperglycemia significantly reduced plasma uric acid by 0.2±0.3 and 0.4±0.3 mg/dl (both P<0.001) while increasing fractional uric acid excretion (by 3.2%±3.1% and 8.9%±4.5%, respectively; both P<0.001). Dapagliflozin reduced plasma uric acid by 0.8±0.8 during fasting, 1.0±1.0 in hyperinsulinemic-euglycemic state, and 0.8±0.7 mg/dl during hyperglycemic conditions (P<0.001), respectively, whereas fractional uric acid excretion in 24-hour urine increased by 3.0%±2.1% (P<0.001) and 2.6%±4.5% during hyperinsulinemic-euglycemic conditions (P=0.003). Fractional uric acid excretion strongly correlated to fractional glucose excretion (r=0.35; P=0.02). In the Uric Acid Excretion study, empagliflozin and benzbromarone both significantly reduced plasma uric acid and increased fractional uric acid excretion. Effects of combination therapy did not differ from benzbromarone monotherapy.

Conclusions

In conclusion, SGLT2 inhibitors induce uric acid excretion, which is strongly linked to urinary glucose excretion and is attenuated during concomitant pharmacologic blockade of urate transporter 1.

Classification of hazardous areas - natural gas installations
Authors: Almeida Julio Cézar de , Sardá Alexandre Pescador , Oliveira Hermes Stefano Ferreira de
Published: March 2022

An explosive atmosphere can be created by a gas or vapor, dust or even fibers. Methane-based risks dominate the gas generation and distribution sector. The probability that any hazard exists in fuel concentration is determined by the specifics of the system under consideration. For example, a natural gas vent line is much more likely to contain this hazard than a lube oil line - unless, of course, the oil line flange joint is leaking. In this work we present the global assessment of the risks of explosion that inevitably involves the definition and classification of hazardous areas with natural gas due to the presence of explosive atmospheres.

Published: March 2022

In this study we sought to develop a non-destructive test that uses the propagation of acoustic waves to characterize the stiffness and hardness of flat glasses. For this purpose, three different glass samples were investigated by using acoustic waves resulting from the impact caused by a steel sphere in free fall on the samples surface. As a result, it was found that the glass samples have different vibration frequency and this behavior is associated to the Young’s modulus and microhardness, values. The values calculated by the ultrasonic transmission method indicated that the increase in stiffness is related to the appearance ofamplitude peaks in the acoustic signal of the samples, attesting to the possibility of the method for characterizing the mechanical properties of glasses used in civil building.
Public procurement in construction: international practice
Authors: Gusakova Elena A. , Pavlov Alexander S.
Published: March 2022

Introduction. The distribution and receipt of design and construction orders is a most important element in the construction life cycle. It is of considerable interest to study the rules governing the distribution of state orders and the practice of their application in various countries. This article examines the experience of the leading world economies accumulated in the bidding for construction projects.

Materials and methods. The authors studied original legal documents on the organization of tenders for construction works in several countries, as well as in international organizations. The tender rules of the USA, France, Germany, New Zealand, Japan, China are considered. Materials of reviews and scientific researches, conducted by other scientists, are also used and summarized.

Results. The principal methods for organizing tenders for construction and design works were identified as a result of analysis of regulatory documents. The authors have found many common approaches and methods used to assure equal and responsible relations between the state customer and the construction contractor.

Conclusions. It has been established that a number of methods, widely used abroad, are practically not used in Russia, for example, competitive negotiations and two stage tendering. On the contrary, a foreign reader may think that some provisions of the Russian legislation are strange, for example, initial contract price setting by the customer or electronic document management rules in the federal law.

Product-based and knowledge-based sustainable living practices: The case of IKEA
Authors: Yurt Canberk , Deniz Deniz
Published: March 2022

Sustainable living is a key concept for eco-friendly lifestyles in consumer societies. Two major sustainable living solutions are based on knowledge and product. Their roles and impacts on sustainable living are controversial. Despite offering innovative approaches to sustainability solutions, products are consumption-dependent. On the contrary, knowledge-based solutions are resource-intensive, while technically resources are limited. This research analyzed the advantages and disadvantages of knowledge-based and product-based sustainable living solutions through a survey regarding environmental sensitivity and sustainable lifestyles from a specific local market. This study highlighted IKEA as the case. From the consumer’s point of view, some IKEA sustainable living dimensions are more knowledge-based, yet the rest of them are product-based. For holistic sustainable living solutions, the combination of the two is crucial. The findings of this study suggest strategies to increase individual and corporate awareness of sustainable living practices from knowledge and product perspectives. In this respect, this study is valuable for IKEA and other companies to revise their strategies in promoting sustainable living and guide sustainable consumer behavior.

Contemporaneous Emotion Regulation Theoretical Models: A Systematic Review
Authors: Cremades Camila Florencia , Garay Cristian Javier , Etchevers Martín Juan , Muiños Roberto , Peker Graciela Mónica , Gómez Penedo Juan Martín
Published: March 2022

Background: Emotions and their regulation are a phenomenon present in everyday life. Despite its relevance and growing interest, a consensual and univocal definition has not yet been reached. Objective: This paper aims to review contemporary theoretical models of emotion regulation, looking for agreements and divergences between authors. It seeks to identify the main processes considered when working with emotional dysregulation. Method: Our team conducted a systematic review in the form of a narrative synthesis following the guidelines of the PRISMA statement. The database used were SCOPUS, PUBMED, and Dialnet. We included articles published between 2018 and 2020, which have been peer-reviewed in indexed scientific journals, whose central theme was the theoretical presentation of the construct of emotional regulation. We excluded articles that conceptualized only one dimension of the construct focused on specific populations and empirical studies without a theoretical conceptualization of the construct. The information was systematized in a table identifying authors' information, country of institutional affiliation, main characteristics of the given definition of emotion regulation, regulation skills mentioned, and underlying theoretical frameworks. Results: We identified ten different theoretical frameworks that propose models of emotion regulation. The main components found in the definition were the complexity of the construct, goal orientation, intra- or interpersonal regulation, the proposal of moderators, and its voluntary character. Discussion: There is a consensus on the use of emotion regulation strategies to adapt to environmental demands, achieve goals and increase well-being. We identify that people's learning history is an important factor in the development of emotional regulation skills. In addition, context and personality traits are proposed as moderators of the therapeutic efficacy of interventions focused on emotional regulation. Further studies along these lines would favor the implementation of preventive interventions and the personalization of treatments.

Published: March 2022

The paper presents the results of a study of the phytoplankton of small Lake Vendyurskoe (south of Karelia) in the spring ice period, in summer and autumn seasons of 2020. The dynamics of quantitative and structural indices of lake algae during the trout farm operation is considered in comparison with the indices of previous years. For the studied seasons of 2020 there were identified 122 taxa of algal flora belonging to 8 divisions. The structure of algocenoses can be characterized by rich species diversity and quantitative development as diatom green structure with golden algae insertions. In autumn the representatives of cyanobacteria were encountered en masse in some areas. Phytoplankton abundance in the spring ice period varied within 612 thousand cells/l - 2188 thousand cells/l, the biomass reached 2.9 mg/l with a minimum value of 0.1 mg/l. Phytoplankton abundance for the studied summer period of 2020 averaged 2216±796 thousand cells/l with a maximum value of 3986 thousand cells/l, the average biomass in the lake did not ex-ceed 1.325±0.504 mg/l. Phytoplankton abundance in autumn averaged 4934±1665 thousand cells/l with a maximum value of 7832 thousand cells/l; biomass averaged 5.8±1.5 mg/l with a maximum value of 7.9 mg/l. According to the eco-logical and geographical characteristics, most representatives of the algal flora found in the lake are widespread freshwater organisms belonging to the planktonic flora and preferring a neutral reaction of the environment. The Shannon index increased from 2.8 in the center of the lake to 3.3 in the trout farming area, which indicates good species diversity. The Sorensen index of 0.8 revealed the homogeneity between phytoplankton communities in different areas of the lake. Most of the identified types of saprobity indices belong to the representatives of the

β-mesosaprobic and oligo-beta-mesosaprobic zones (up to 78% of the total number of identified indicator species). The saprobity index corresponded to the 2nd class of water purity (pure, α-oligosaprobic), which is due to the species composition of the dominant phytoplankton complex, however, the biomass indicates that the lake belongs to the 3rd class of water purity (satisfactorily clean, β-mesosaprobic).

The sturgeon fish populations in the main reservoirs of the country are in a crisis. Efficiency of natural reproduction of these fish species is extremely low and currently the replenishment of populations is mainly achieved due to artificial breeding. Beluga, one of the sturgeon fish species living in the Caspian basin, is classified as endangered, being in particularly difficult circumstances. Over the past hundred years its abundance has undergone fluctuations due to the natural and anthropogenic factors. Due to the sharp reduction in the volume of artificial reproduction by fish hatcheries of the Lower Volga and the threat of species extinction there was carried out the research of the quality of beluga juveniles of different ages cultivated in artificial environment. Morphophysiological parameters of beluga juveniles of different ages cultivated in cages and ponds are investigated. The concentration of hemoglobin in the studied groups ranged from 56.3 to 70.3 mg/l (the data were within the reference values), which indicates an increased level of metabolism. Low values of the erythrocyte sedimentation rate in different growing conditions (from 4.5 – 6.4 mm/h) were noted, which indicates the absence of inflammatory or pathological processes in the body of hydrobionts. Concentration of total whey protein in the studied groups was also within the physiological norm. As a result of the studies, it can be concluded that such parameters as total protein, cholesterol, glucose and β-lipoproteins are not affected by age, but mainly depend on fish nutrition. The obtained analysis of sturgeon morphophysiological indicators (grown in different conditions) complements the missing information for monitoring the physiological state of these valuable representatives of aquaculture, adjusting biological standards of cultivation and the technological processes in the ponds and industrial complexes.

Ensuring stable power supply and proper electric power quality while continuously managing the production, transmission and distribution of electricity is the main goal of the dispatch center of any power system, including an isolated one. Continuous management is based on an electric power regime planning process. According to its results, the dispatch center sends to the electric power industry entity the planned dispatch schedule of the power generation, transmission and consumption in an hourly (half-hour) breakdown, which has to be received by the managed entity 8–10 hours before the onset of the planned day. In the operational management of the electric power regime, the dispatch center operators on duty adjust (update) the values of the planned dispatch schedule. Active power consumption in the power system is one of the most significant parameters being updated. The possibilities of improving the accuracy of operationally forecasting active power in isolated power systems are investigated taking the Kaliningrad power system as an example. The existing power consumption forecasting methods are analyzed. The influence of power plant auxiliaries on the total active power consumption in the power system is studied. Methodological principles for operational forecasting of power consumption have been developed and proposed, which are recommended for inclusion in regulatory documents as a methodology. The proposed methodology is based on a mathematical model that takes into account the consumed power variation rate on a typical day, forecasted meteorological data and the dependence of power consumption for power plant auxiliaries on the composition of the generating equipment switched in operation.

Possible solutions of protection systems against short-circuit currents and for preventing the occurrence of emergencies depending on the power plant electric power output capacity are considered. A current limiting device for a hybrid electric power complex containing photovoltaic and wind power installations has been developed. The device physical principle consists of using two magnetically coupled reactors, the windings of which are connected in parallel to the load circuit, but oppositely in the winding magnetic flux directions. The magnetic fluxes of the reactors are mutually compensated. The power line current is strictly equally divided between the reactor windings, because the current divider effect manifests itself with exactly such connection of the windings. By using the device, the fault current peak amplitude is limited on a time interval of about 100–120 ms after disconnection of the mains circuit breaker. The steady-state fault current is limited at a level close to the rated current value. The electromagnetic processes occurring in the developed device have been studied on a computer model.

Degradation of the internal insulation electrical strength is one of the main factors leading to failures of high-voltage oil-filled transformers. To a certain extent, this is due to structural shortcomings laid down at the design stage. Correct calculation of the transformer main insulation will help ensure their reliable operation within the standard service life. The experience gained with design, manufacture and operation of high-voltage oil-filled transformers, as well as new modern manufacturing technologies generate the need to develop new methods and approaches to the calculation of their insulation structures. An approach to calculation and design of transformer insulation is proposed, which takes into account the influence of the oil channel volume on the breakdown field strength at various points of insulation, as well as electrical strength statistical characteristics when exposed to various voltage waveforms under operating conditions. Using the ANSYS MAXWELL software package, the insulation structures of power transformers were calculated. A model of a 110 kV two-winding three-phase transformer's main insulation is constructed in two 2D projections. The model takes into account the design features of the main insulation of oil-barrier type power transformers: the distance between the windings and the distance from the windings to barriers and capacitive rings. By using the proposed approach it becomes possible to achieve better calculation accuracy and take into account the transformer design features and significantly larger number of influencing factors in designing the transformer insulation.
CONSUMERS’ PERCEPTION: DISCOVERING THE “LAW OF ATTRACTION” IN ART USING EYE-TRACKING

Today, due to new technologies and seeing the tenacity with which the branch of scientific research, especially neuromarketing, advances, it is easy to understand how they have managed to bring together topics such as fine arts and eye-tracking technology. Not only did they end up with amazing results, but those results were in line with the expectations created from the very beginning by researchers from these industries and beyond. Therefore, using eye-tracking as a market research tool, it is possible to directly track and measure the observable behavior of a visual arts consumer, analyzing both his visual attention and his eye movements. The data collected for this study resulted from the exploratory research, which involves the review of several articles and specialized studies regarding the eye-tracking subject and also from the qualitative research, represented by an in-depth interview with both Romanian art consumers and artists. It has implemented an eye-tracking test, also to gather the primary data for this present study, a tool that was available on an online platform named GazeRecorder. The results illustrate the extent to which attention and the decision-making process (to purchase a painting) affect and influence how the information present in the work of fine art is related to the composition and elements that support the artwork itself. Thus, these results, not only can help analyze a painting in a much more efficient way but can also be incorporated in the future into consultancy services for artists or may represent the basis of a more appropriate and attractive form of education in art.

Mujeres en las artes del espectáculo. Condiciones laborales, demandas de derechos y activismos de género (Argentina, 2015-2020)
Authors: Bulloni María Noel , Justo von Lurzer Carolina , Liska Mercedes , Mauro Karina
Published: March 2022

Durante la última década, la discusión articulada sobre las condiciones generizadas y desiguales de trabajo productivo y reproductivo en todas las ramas de actividad social y en alianza internacional se ha traducido también en modos de organización y activismo en las artes del espectáculo. Este artículo pone en diálogo cuatro trayectorias de investigación para indagar las desigualdades de género, los procesos de debate y las demandas de derechos en torno a las condiciones laborales de las mujeres en las artes del espectáculo en Argentina a partir de 2015.
Feminización de la denominación de profesiones, títulos y oficios en francés metropolitano. Revisión bibliográfica sobre los principales puntos de debate (2002-2019)
Authors: Nazzarro Magalí
Published: March 2022

En este estudio se abordan las posturas y argumentos en torno a la denominación de profesiones, títulos y oficios en francés metropolitano durante el periodo 2002-2019, cuyo eje de debate es el valor neutro y genérico del género gramatical masculino. Dichos argumentos utilizan criterios históricos, estéticos y también ideológicos. Mientras que los detractores se focalizan en nivel puramente lingüístico, los promotores consideran la lengua como una práctica social en la cual se refleja y alimenta la asimetría representativa del masculino genérico. La Academia Francesa hace eco de esta desigualdad al oponerse a la feminización de ciertos cargos jerárquicos.
Trayectorias del sufragio femenino en Tucumán: los proyectos durante el Segundo Congreso de Municipalidades (1928)
Authors: Segura María Marta
Published: March 2022

En Argentina, la década de 1920 fue prolífica en la aparición de proyectos que bregaban por los derechos políticos de las mujeres. Los estudios de caso realizados hasta el momento nos develaron los recorridos a nivel provincial y municipal en Santa Fe y San Juan. En este mismo sentido, es el objetivo de este artículo analizar los proyectos de sufragio femenino presentados en 1928 en el Segundo Congreso de Municipalidades de Tucumán y sus protagonistas: Defensa Comunal Bandera Blanca y el gremialismo docente de la provincia, la Asociación Magisterial de Monteros y la Federación de Maestros Tucumanos.
Espectadores de cine en la obra de Woody Allen
Authors: Casado Pérez Francisco
Published: March 2022

El cine de Woody Allen siempre ha prestado especial predilección por el ritual de la sala cinematográfica y por cómo los espectadores que a ella acuden valoran y sienten las películas que ven.  El propio Woody Allen es un espectador más de las obras de otros artistas, mostrando en muchas ocasiones su veneración por ellos. Pero desde su punto de vista como creador, a lo largo de su obra, sitúa a sus personajes como espectadores en cines, museos y teatros, así como lectores de grandes obras de la literatura universal. Así, se vislumbra cómo los personajes no-artistas hacen uso de manifestaciones como el cine, la música y la radio, desde su condición de meros espectadores que usan el arte como evasión, prefiriendo en algunos casos este a la vida. Mediante el análisis centrado en los personajes de Recuerdos (Allen, 1980), La rosa púrpura del Cairo (Allen, 1985) y Días de radio (Allen, 1987) se contemplarán varios tipos de espectadores dentro de la obra del director neoyorquino: estos amalgaman las diferentes miradas que se pueden apreciar a la hora de enfrentarse a una pantalla de cine, a la obra que se disfruta y al artista que la realiza. En una época, la actual, en la que la sala de cine está perdiendo su aura en beneficio de opciones más caseras, resulta de interés observar de qué modo, entre la amargura y la nostalgia, aparecen reflejadas las miradas de varios espectadores de ficción.
Lo que la verdad esconde

El espejo ha sido un motivo recurrente a lo largo de la Historia del Arte. Su iconografía ha estado asociada, además, con significados ambivalentes, cuando no directamente contradictorios, en función del momento histórico en el que se utilizaron por parte de los artistas en sus composiciones. En el siglo XX, el arte del cinematógrafo recogió con entusiasmo esta tradición convirtiéndolo en un elemento que, utilizado con sutileza, enriqueció la puesta en escena de muchísimas películas. Este trabajo pretende esbozar una aproximación al tratamiento iconográfico que el espejo ha tenido en la gran pantalla, centrando fundamentalmente su atención en el período que va desde los inicios del cine sonoro hasta la irrupción de las vanguardias cinematográfica a finales de los años cincuenta.
Dj’s@work: fiesta en cabina y sacerdotes del trance

Published: March 2022

A nadie escapa que el videoclip es una Imago Musicae abierta al experimentalismo estético, siempre presta a la caza y captura oportunista de la cita y el fragmento. Igualmente, se muestra susceptible de trazar sinergias, transferencias e interferencias con el arte moderno y el arte histórico para generar una nueva imaginería al servicio de los flamantes ídolos, necesidades y expectativas de la sociedad de consumo. En otras ocasiones, abordamos la fenomenología de las subculturas urbanas y su interrelación con los movimientos musicales y el videoclip, concretándola en cinco estudios de caso -new romantic, techno, hard rock/heavy metal, rappers y DJs- que permitieron perfilar/ratificar/establecer identificadores y claves iconográficas precisas para su reconocimiento y puesta en valor. Ahora, seguimos profundizando en la validez del método iconográfico aplicado al videoclip como género mediático creador de nuevas mitogenias e instrumento de difusión de valores, inquietudes y atributos de grandes tendencias músico-culturales desde 1981 hasta hoy. Nos detendremos en valores específicos que permiten diseccionar los factores claves para construir mitogenias particulares, sin olvidar establecer/codificar premisas ad hoc para reconocer/distinguir/poner en valor la significación del DJ en la cultura popular de nuestro tiempo. También estudiamos su iconografía, apoyándonos en los videoclips referenciales y otros productos mediáticos.

Penelitian ini bertujuan untuk mengkaji hubungan antara panggilan dan keterikatan kerja yang dimediasi oleh komitmen karir. Melalui teknik purposive sampling diperoleh 82 guru Sekolah Menengah Pertama dengan minimal masa kerja 1 tahun. Penelitian ini menggunakan instrumen Calling and Vocation Questionnaire, The Career Commitment Scale, dan Utrecht Work Engagement dengan nilai validitas dan reliabilitas yang tergolong baik. Melalui teknik analisis regresi dengan menggunakan Process Macro model mediasi 4, diperoleh hasil bahwa komitmen karir memediasi secara parsial hubungan panggilan dan keterikatan kerja. Guru yang meyakini pekerjaannya sebagai panggilan akan lebih memiliki komitmen terhadap karirnya dan menunjukkan keterikatan yang kuat dengan pekerjaannya. Guru akan tampak berenergi, antusias, berdedikasi, dan menikmati pekerjaannya. Sekolah dapat membantu guru menyadari panggilan dalam pekerjaan agar terus memiliki motivasi dalam menjalani perannya sebagai guru, penuh semangat, dan dedikasi saat bekerja.
