Diseño de un módulo de capacitación sobre el estrés laboral en personal comercial operativo del sector financiero

Curso de Especial Interés: Management de Gestión HumanaEl objetivo del presente trabajo es diseñar un programa de identificación para la prevención primaria del estrés laboral en la población de adultos que trabajan en las áreas administrativas y operativas comerciales del sector financiero, en la ciudad de Bogotá, zona sur occidente. Para esto se hizo una exhaustiva revisión teórica, la cual permitió identificar las variables que se ven afectadas con el estrés laboral específico para estos cargos. Para el desarrollo del programa se tuvo en cuenta el modelo demanda-control de Vega (2001) en el que afirma que el estrés surge de las demandas psicológicas laborales y las características del trabajo, versus la toma de decisiones y las habilidades para hacerle frente a estas demandas. El programa fue diseñado para aprender a identificar signos y síntomas propios del estrés laboral que tienen mayor impacto en este tipo de cargos laborales, en el que se enseñan las generalidades del estrés, el estrés laboral, signos y síntomas, factores de riesgos, factores protectores y una serie de recomendaciones que se le hacen a los participantes del programa para que la primera intervención ante la presencia de estos signos y síntomas sea realizada por ellos mismos y por la empresa de la que hacen parte.El estrés, el detonante de las enfermedades en el siglo XXI.

Cluster Analysis of Smart Metering Data - An Implementation in Practice

The introduction of smart meter technology is a great challenge for the German energy industry. It requires not only large investments in the communication and metering infrastructure, but also a redesign of traditional business processes. The newly incurring costs cannot be fully passed on to the end customers. One option to counterbalance these expenses is to exploit the newly generated smart metering data for the creation of new services and improved processes. For instance, performing a cluster analysis of smart metering data focused on the customers’ time-based consumption behavior allows for a detailed customer segmentation. In the article we present a cluster analysis performed on real-world consumption data from a smart meter project conducted by a German regional utilities company. We show how to integrate a cluster analysis approach into a business intelligence environment and evaluate this artifact as defined by design science. We discuss the results of the cluster analysis and highlight options to apply them to segment-specific tariff design

The role of trunk training for physical fitness and sport-specific performance. Protocol for a Meta-Analysis.

The trunk (core) muscles are involved in daily functions (i. e., stabilizing the body in everyday tasks) and force generation of the limbs during athletic tasks such as kicking, throwing, or running. Even though trunk training is a popular means for improving physical fitness and athletic performance, the direct relationship of improved trunk function (i.e., stability, strength, or endurance), fitness and sport-specific performance is not conclusive. The aim of this proposed review is to evaluate the effects of trunk training on physical fitness and sport-specific performance, and to examine potential subject-related (e.g., age, sex) and trunk training-related moderator variables (e.g., training period, training frequency) for performance changes. We will conduct a systematic literature search in Web of Science, MEDLINE (via EBSCO) and SportDiscus. Relevant papers will be screened independently by two reviewers in two stages: (1) title and abstracts and (2) the full text of the remaining papers. A third reviewer will resolve possible disagreements. Data extraction and risk of bias of the included studies will be performed in addition to the PEDro scoring to judge the quality of the studies. A meta-analysis will be conducted to determine the efficacy of trunk training to increase physical fitness and sport-specific performance measures. In addition, subgroup univariate analyses were computed for subject-related (i.e., age, sex, performance level) and training-related moderator variables (i.e., training period, training frequency, training sessions, session duration). The results of this proposed systematic review and meta-analysis will assess the effects of trunk training on physical fitness and sport-specific and identify which subject-related and training-related moderate variables of trunk training modality might be beneficial for performance gains. This knowledge has potential importance for athletes and coaches in sports.publishedVersio

OSPAR-metodikk og plastanalyse av strandsøppel fra Nordre Langåra og Akerøya

Prosjektleder Inger Lise Nerland BråteMer strandsøppel ble registrert på Akerøya (fra 2018) fra Ytre Hvaler, enn Nordre Langåra (fra 2019) fra Indre Oslofjord, men det er usikkert om disse tallene er robuste nok til å konkludere med at Akerøya har større plastbelastning enn Nordre Langåra. Mesteparten av avfallet, målt i antall, som ble funnet i både indre og ytre Oslofjord var fiskerirelatert, og mye av dette var såkalte «dollyropes». Den nest mest vanlige kategorien var uidentifiserbare plastbiter som trolig har mange diffuse kilder. Det var polyetylen (PE) og polypropylen (PP) som dominerte på begge strendene. Dette kan skyldes at disse polymertypene er de mest produserte og brukte plasttypene, samt at de som oftest flyter i sjøvann. Mesteparten av søpla fra ytre Hvaler ble antatt å ha norsk opphav, men av det utenlandske avfallet antas det å være bidrag fra 43 land. OSPAR-metodikken er svært verdifull og på nåværende tidspunkt det beste verktøyet vi har for å registrere strandsøppel for å se på mengde og komposisjon av strandsøppel i Nordøst-Atlanteren. Det er likevel flere forbedringspunkter ved OSPAR-metodikken; blant annet foreslås det å inkludere vekt for de ulike kategoriene, samt inter-kalibrere rydding mellom strender for å harmonisere metoden.Handelens MiljøfondpublishedVersio

Análisis mediante elementos finitos de cargas de impacto sobre el irradiador de Cobalto 60 de la Escuela Politécnica Nacional del Ecuador.

En el presente trabajo se determinó el posible agrietamiento en los muros estructurales y efectos en el funcionamiento del Irradiador Gamma Panorámico Categoría IV con Fuente de Cobalto 60 que se encuentra en el interior del Edificio n.º 7 de la Escuela Politécnica Nacional (EPN), en Quito. El estudio consistió en analizar el impacto de una parte del techo que está sobre el irradiador de la instalación denominada “CASAMATA”, puesto que gracias a un estudio previo de esta estructura se demostró que es vulnerable debido a sus características, construcción y deterioro a lo largo del tiempo. El estudio se realizó en función de requisitos de normas de análisis y evaluación de estructuras existentes, mediante la utilización del software denominado “SAP2000” para la modelación del irradiador. Se realizaron seis modelaciones con diferentes características en cuanto a hormigón y acero de refuerzo para determinar el comportamiento de la estructura bajo los casos asumidos. De los resultados obtenidos mediante SAP2000 se observó que en algunos lugares del irradiador se tienen valores mayores a los máximos permitidos en el American Concrete Institute 349 (ACI 349), correspondientes a la deformación unitaria del hormigón el cual es de 0.003 m/m. Además, los requisitos de resistencia señalados en la misma norma, no cumplieron con los parámetros establecidos, lo cual provoca que exista un peligro radiológico debido a que la cámara de radiación no cumpliría con el blindaje para la cual fue diseñada y liberaría una tasa de dosis mínima de 1.13x106 [mSv/año]The present work determines the possible cracking in the structural walls and effects on the operation of the Category IV Panoramic Gamma Irradiator with Cobalt 60 Source, which is located inside Building No. 7 of the National Polytechnic School (EPN) in Quito. The analysis consisted of an alleged (supposed) impact of a roof section that is on the irradiator in the facility called “CASAMATA”, since a previous study of this structure showed that it is vulnerable due to its characteristics, construction, and deterioration throughout the time. The study was carried out based on the requirements of analysis and evaluation standards of existing structures by using the software called SAP2000 for modeling the irradiator. Six models with different characteristics in terms of concrete and reinforcing steel were made to determine the behavior of the structure under the assumed cases. From the results obtained through SAP2000, it was observed that in some places of the irradiator there are values greater than the maximum allowed in the American Concrete Institute 349 (ACI 349) corresponding to the unitary deformation of the concrete, which is 0.003 m/m. In addition, the resistance requirements indicated in the same standard did not meet the established parameters, which causes a radiological hazard because the radiation chamber would not comply with the shielding for which it was designed and would release a minimum dose rate of 1.13x106 [mSv/year]

A research framework for projecting ecosystem change in highly diverse tropical mountain ecosystems

Tropical mountain ecosystems are threatened by climate and land-use changes. Their diversity and complexity make projections how they respond to environmental changes challenging. A suitable way are trait-based approaches, by distinguishing between response traits that determine the resistance of species to environmental changes and effect traits that are relevant for species\u27 interactions, biotic processes, and ecosystem functions. The combination of those approaches with land surface models (LSM) linking the functional community composition to ecosystem functions provides new ways to project the response of ecosystems to environmental changes. With the interdisciplinary project RESPECT, we propose a research framework that uses a trait-based response-effect-framework (REF) to quantify relationships between abiotic conditions, the diversity of functional traits in communities, and associated biotic processes, informing a biodiversity-LSM. We apply the framework to a megadiverse tropical mountain forest. We use a plot design along an elevation and a land-use gradient to collect data on abiotic drivers, functional traits, and biotic processes. We integrate these data to build the biodiversity-LSM and illustrate how to test the model. REF results show that aboveground biomass production is not directly related to changing climatic conditions, but indirectly through associated changes in functional traits. Herbivory is directly related to changing abiotic conditions. The biodiversity-LSM informed by local functional trait and soil data improved the simulation of biomass production substantially. We conclude that local data, also derived from previous projects (platform Ecuador), are key elements of the research framework. We specify essential datasets to apply this framework to other mountain ecosystems

Individual and culture-level components of survey response styles: a multi-level analysis using cultural models of selfhood

Variations in acquiescence and extremity pose substantial threats to the validity of cross-cultural research that relies on survey methods. Individual and cultural correlates of response styles when using two contrasting types of response mode were investigated, drawing on data from 55 cultural groups across 33 nations. Using seven dimensions of self-other relatedness that have often been confounded within the broader distinction between independence and interdependence, our analysis yields more specific understandings of both individual- and culture-level variations in response style. When using a Likert scale response format, acquiescence is strongest among individuals seeing themselves as similar to others, and where cultural models of selfhood favour harmony, similarity with others and receptiveness to influence. However, when using Schwartz’s (2007) portrait-comparison response procedure, acquiescence is strongest among individuals seeing themselves as self-reliant but also connected to others, and where cultural models of selfhood favour self-reliance and self-consistency. Extreme responding varies less between the two types of response modes, and is most prevalent among individuals seeing themselves as self-reliant, and in cultures favouring self-reliance. Since both types of response mode elicit distinctive styles of response, it remains important to estimate and control for style effects to ensure valid comparisons

Being oneself through time: bases of self-continuity across 55 cultures

Self-continuity – the sense that one’s past, present, and future are meaningfully connected – is considered a defining feature of personal identity. However, bases of self-continuity may depend on cultural beliefs about personhood. In multilevel analyses of data from 7287 adults from 55 cultural groups in 33 nations, we tested a new tripartite theoretical model of bases of self-continuity. As expected, perceptions of stability, sense of narrative, and associative links to one’s past each contributed to predicting the extent to which people derived a sense of self-continuity from different aspects of their identities. Ways of constructing self-continuity were moderated by cultural and individual differences in mutable (vs. immutable) personhood beliefs – the belief that human attributes are malleable. Individuals with lower mutability beliefs based self-continuity more on stability; members of cultures where mutability beliefs were higher based self-continuity more on narrative. Bases of self-continuity were also moderated by cultural variation in contextualized (vs. decontextualized) personhood beliefs, indicating a link to cultural individualism-collectivism. Our results illustrate the cultural flexibility of the motive for self-continuity

Beyond the ‘East-West’ dichotomy: global variation in cultural models of selfhood

Markus and Kitayama’s (1991) theory of independent and interdependent self-construals had a major influence on social, personality, and developmental psychology by highlighting the role of culture in psychological processes. However, research has relied excessively on contrasts between North American and East Asian samples, and commonly used self-report measures of independence and interdependence frequently fail to show predicted cultural differences. We revisited the conceptualization and measurement of independent and interdependent self-construals in 2 large-scale multinational surveys, using improved methods for cross-cultural research. We developed (Study 1: N = 2924 students in 16 nations) and validated across cultures (Study 2: N = 7279 adults from 55 cultural groups in 33 nations) a new 7-dimensional model of self-reported ways of being independent or interdependent. Patterns of global variation support some of Markus and Kitayama’s predictions, but a simple contrast between independence and interdependence does not adequately capture the diverse models of selfhood that prevail in different world regions. Cultural groups emphasize different ways of being both independent and interdependent, depending on individualism-collectivism, national socioeconomic development, and religious heritage. Our 7-dimensional model will allow future researchers to test more accurately the implications of cultural models of selfhood for psychological processes in diverse ecocultural contexts
