Copernicus observations of Betelgeuse and Antares

Copernicus observations of the M-supergiants, alpha Ori and alpha Sco, are presented. The MgII h and k resonance lines are strongly in emission in both stars. The k line is highly asymmetric in both stars but the h line is symmetric. Upper limits for several other resonance lines are given for alpha Ori. The possibility is explored that the k line asymmetry is caused by overlying resonance lines of MnI and FeI formed in the cool circumstellar gas shells around these stars. Observations of the MnI 4030-4033 A lines are used to show that circumstellar shell absorption is too weak to explain the asymmetry. It is suggested that the absorption occurs in a cool turbulent region between the base of the circumstellar shell and the top of the chromosphere

State-Corporate Crime and the Process of Capital Accumulation: mapping a global regime of permission from Galicia to Morecambe Bay

This paper seeks to develop the principal concerns of the state-corporate crime literature by drawing connections between two incidents that occurred 15 months apart: the sinking of the oil tanker the Prestige in Galicia in November 2002 and the killing of 24 Chinese migrant workers at Morecambe Bay in the North West of England in February 2004. It begins by introducing the key features of the two cases, before exploring how they might be described and understood as state-corporate crimes. It then identifies a tendency within the literature to analyse state-corporate crimes as ‘moments of rupture’ in the regulatory relationship. Seeking to move beyond such ‘moments of rupture’, the paper argues for an understanding of regulatory relationships as part of a broader regime of permission that seeks the smooth and uninterrupted accumulation of capital. It thus identifies the ‘process’ that must be analysed as a process of capital accumulation. This process is illustrated by focussing on the spheres of production and distribution in this story of capital accumulation. In the course of describing the complex ‘regime of permission’, the paper uncovers a structure of impunity that generally enables the most powerful architects and beneficiaries of state-corporate crime to sustain a process of capital accumulation

Measuring dispositional cancer worry in China and Belgium: a cross-cultural validation

Dispositional cancer worry (DCW) is the uncontrollable tendency to dwell on cancer independent of relevant stimuli (e.g., diagnosis of the disease). Past research has suggested that DCW has two underlying dimensions: severity and frequency. Available measures of DCW severity and frequency were translated and validated in two countries: China and Belgium. Participants (N = 623) completed translated scales, as well as measures of general dispositional worry, cancer fear, and perceived risk. In both locations, DCW measures were reliable (Cronbach's alphas ranged from .78 - .93) and demonstrated strong convergent, divergent, and concurrent validity. Severity and frequency factors loaded as expected in exploratory factor analysis. Future research should pursue longitudinal tests of DCW's predictive validity and explore DCW in theoretical models predicting the relationship between worry and cancer prevention and early detection behaviors

Perencanaan Desain Tapak Jasa Lingkungan Wisata Alam Di Hutan Lindung Gunung Mahawu

The main objective of this study is to develop a site design for planning the development and management of natural tourism environmental services that are harmonious and harmonious with the natural environmental conditions in the Mount Mahawu Protection Forest by describing the potential, potential distribution and site analysis of each potential natural tourist attraction object. This research began in March to May 2023. The data used in this study were secondary data and primary data. Survey methods namely observation and inventory are used to obtain primary data in the form of biophysical data on research locations, types of potential natural tourist attraction objects as well as information on flora and fauna obtained at potential ODTW points determined by purposive sampling. Secondary data was obtained from a literature study as well as data from related institutions, namely the Forest Management Unit V of the Regional Forestry Service of North Sulawesi Province. The results showed that there were 6 forms of Land Mapping Unit (LMU) and 7 Land Utilization Types (LUT). The level of feasibility of developing ODTW potential consists of low to high categories. The high potential category is in LMU V and VI. LMU II is in the medium category class, LMU I, III and IV are in the medium and low categories. Alternatives to developing management space consist of business space covering an area of 522.663 Ha and public space of 53.265 Ha or 9.25% of the total site area by considering ecological, policy, technical and socio-cultural aspects

Perceptual properties of feedback stimuli influence the feedback‐related negativity in the flanker gambling task

A negative deflection in the event‐related potential is enhanced following error‐ and loss‐related feedback in decision‐making and simple gambling tasks. Researchers have assumed that the perceptual properties of the feedback stimuli are unimportant in explaining these effects. This assumption was tested in the present study through a flanker gambling task, in which the perceptual properties of the feedback were manipulated. Consistent with previous studies, loss elicited a larger feedback‐related negativity ( FRN ) than gain feedback. However, this FRN reward effect was modulated by the perceptual properties of the feedback stimuli. When gain and loss feedback were perceptually similar to each other, the enhancement of the FRN following the loss feedback was smaller compared to when the gain and loss feedback were different from each other. In addition, incongruent feedback elicited a larger FRN than congruent feedback; this FRN congruency effect was larger following gain than loss feedback. These results suggested that perceptual properties of the feedback stimuli play a role in the elicitation of the FRN .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/108013/1/psyp12216.pd

Awareness of Online Library Services and Frequency of Utilization of Online Resources during Covid- 19 Pandemic among Education Students

As the Covid-19 greatly affected the libraries, so too did the librarians\u27 attempts to reach the library users through online and remote services. These emergency reforms have offered an unexpected opportunity to re-evaluate and re-imagine current service models in order to improve the library\u27s user experience. This study looks into the awareness of online library services and the frequency of utilization of online resources among education students during the COVID 19 Pandemic. Descriptive in nature, the study utilized an online survey which was accomplished by 70 students of the College of Education. Findings revealed that respondents are fully aware of the online library services and they frequently utilize the library\u27s online resources regardless of their gender, program, and year level. Findings also showed that the higher the level of respondents’ awareness on online library services, the more frequent they utilize the online resources. As a whole, the results imply that libraries need to ensure the sustainability of their online resources and services by providing user education and supporting the users to cope-up with the changing information environment so that optimum use of information resources becomes possible during and after the pandemic

EVOLUCIÓN DE LAS DIFERENCIAS SALARIALES POR SEXO EN SEIS PAÍSES DE AMÉRICA LATINA UN INTENTO DE INTERPRETACIÓN

Este documento analiza la evolución de las diferencias más marcadas por género en los mercados laborales de seis países de América Latina. Se estudian la participación laboral, el desempleo, las oportunidades de trabajo y los ingresos durante las dos últimas décadas del Siglo XX. Los resultados en la situación de la mujer en el Mercado laboral son mixtos: por un lado, los diferenciales de salarios por hora han disminuido significativamente, y, por otro lado, el acceso de la mujer al empleo también ha disminuido relativamente al masculino. La segmentación del mercado observada no parece ser responsable las diferencias observadas en salarios por hora. Antes bien, las diferencias observadas en salarios por hora entre hombres y mujeres parecen estar asociadas con patrones de remuneración laboral al interior de sectores y al interior de ocupaciones. El análisis realizado de regresión de ingresos sugiere que los diferenciales en salarios por hora disminuyen al aumentar el capital humano, indicando que aunque es posible que todavía queden rezagos de discriminación en contra de las mujeres, esta discriminación es estadística (a la Phelps), más que basada en prejuicios contra el género femenino. El tipo de discriminación que persiste es el basado en los roles tradicionales femeninos que todavía hacen de la mujer la más responsable por la administración del hogar y el cuidado de los hijos.diferencial salarial

Switcher-random-walks: a cognitive-inspired mechanism for network exploration

Semantic memory is the subsystem of human memory that stores knowledge of concepts or meanings, as opposed to life specific experiences. The organization of concepts within semantic memory can be understood as a semantic network, where the concepts (nodes) are associated (linked) to others depending on perceptions, similarities, etc. Lexical access is the complementary part of this system and allows the retrieval of such organized knowledge. While conceptual information is stored under certain underlying organization (and thus gives rise to a specific topology), it is crucial to have an accurate access to any of the information units, e.g. the concepts, for efficiently retrieving semantic information for real-time needings. An example of an information retrieval process occurs in verbal fluency tasks, and it is known to involve two different mechanisms: -clustering-, or generating words within a subcategory, and, when a subcategory is exhausted, -switching- to a new subcategory. We extended this approach to random-walking on a network (clustering) in combination to jumping (switching) to any node with certain probability and derived its analytical expression based on Markov chains. Results show that this dual mechanism contributes to optimize the exploration of different network models in terms of the mean first passage time. Additionally, this cognitive inspired dual mechanism opens a new framework to better understand and evaluate exploration, propagation and transport phenomena in other complex systems where switching-like phenomena are feasible.Comment: 9 pages, 3 figures.
