An overview of polarimetric sensing techniques and technology with applications to different research fields

This paper analyses the meaning of astronomical alignments of Structure 44 from Yaxchilan, Mexico. The lack of direct solar referents calls for a more integrative approach in which archaeoastronomy is supplemented by the research fields of archaeology, epigraphy and iconography. The designation of Structure 44 as an otoot (dwelling, house) building allows us to conceptualize it as a type of animate entity which is linked with the representation of the figure of the Starry Deer Caiman, one of the Maya Milky Way constellations.

A Current

The article formulates main questions related to the concept of context. The issue of context is considered as a current-day interdisciplinary field of research. There are many definitions of context in dictionaries and in various humanities (including scientific disciplines). In connection with that issue various methodological approaches arise in the humanities, which can be designated by the umbrella term “contextual”. By the example of one of such approaches to the sociological poetics of the “Bakhtin’s circle”, the author substantiates the possibility of creating an interdisciplinary classification of contextual approaches. That classification may include scientific developments of different years and research fields, including: philosophical hermeneutics, a number of approaches to the Russian and foreign literary theory (M.M. Bakhtin, Yu.M. Lotman, B.M. Eichenbaum, F. Moretti, A. Compagnon, etc.), intellectual history, discourse analysis, etc.

The University

El momento que viven las universidades ecuatorianas, se caracteriza por la búsqueda de una mejora significativa en el campo académico, investigativo y de vinculación con la comunidad. La intervención de algunas universidades por parte del CES, ha sido una medida que se constituye en oportunidad para lograr cubrir las expectativas de la sociedad y de las instancias superiores encargadas de velar por el desarrollo de la Academia. Las deficiencias encontradas develaron las causas principales que aquejan a estas comunidades: el pobre desarrollo de la investigación. En este marco, el presente trabajo se constituye en un tema pertinente, al proyectar una propuesta que se sustenta en la necesidad de formación de la docencia universitaria en el ámbito de la investigación. El análisis que se realiza a la propuesta, tiene un enfoque social pensado en función del servicio que presta la Universidad a la colectividad en aras de responder a la sociedad que concomitante al progreso mundial, apuntala su economía en el desarrollo del conocimiento. Considerar una estrategia para el desarrollo de las competencias investigativas en los docentes universitarios, ayudará a fortalecer la función investigativa, consecuentemente, se generará y crearán condiciones que permitan transferir tecnologías tendientes a mejorar las condiciones de vida del sector. Palabras claves: Docencia universitaria, competencia investigativa, investigación, universidad, estrategia Social view of the strategy for the formation of the research competence in the university professor Abstract The Ecuadorian universities are changing today and that is characterized by the search for a significant improvement in the academic and research fields and the link with the community. The intervention of some universities by the CES has been a measure which constitutes an opportunity to meet the society’s expectations and those of the higher level authorities to ensure the development of the university. The deficiencies found uncovered the main causes affecting these communities: the poor development of research. In this context, the present work constitutes a relevant topic, to project a proposal that is based on the need for training in the field of researching the university teachers. The analysis of the proposal has a social approach, which functions through the service provided by the University to the community in order to respond to the global society concomitant progress that seeks the development of knowledge while developing the world economy. To consider a strategy for the researching competence development in university teachers will help strengthening the researching function. Consequently, it will generate and create conditions for transferring technologies aimed at improving the living conditions of the teachers.

Heterocyclic Derivatives

: Over the last decades, several heterocyclic derivatives compounds have been synthesized or extracted from natural resources and have been tested for their pharmaceutical activities. Xanthene is one of these heterocyclic derivatives. These compounds consist of an oxygen-containing central heterocyclic structure with two more cyclic structures fused to the central cyclic compound. It has been shown that xanthane derivatives are bioactive compounds with diverse activities such as anti-bacterial, anti-fungal, anti-cancer, and anti-inflammatory as well as therapeutic effects on diabetes and Alzheimer. The anti-cancer activity of such compounds has been one of the main research fields in pharmaceutical chemistry. Due to this diverse biological activity, xanthene core derivatives are still an attractive research field for both academia and industry. This review addresses the current finding on the biological activities of xanthene derivatives and discussed in detail some aspects of their structure-activity relationship (SAR).

The study of social movements is currently one of the most active research fields in Latin American sociology. This article maps the vast literature on Latin American social movements (LASMs) from the late 1980s to the present. After briefly discussing how scholars have conceptualized LASMs, it presents seven influential approaches: structuralism, political economy, political context, organizational fields, “new social movements,” frames and emotions, and transnational activism. Then it discusses some works that zero in on the specificity of LASMs. It closes with a brief summary of the five coming chapters, each of which is devoted to a specific social movement “family”: labor, women’s, student, indigenous, and anti-globalization.

Genetic Detection

The Exopalaemon carinicauda could be a useful crustacean laboratory animal in many research fields. We newly established an inbred line of Exopalaemon carinicauda named EC4 inbred line by brother×sister mating and keeping to F11 generation. Trends in heterozygosity in the process of producing EC4 inbred line were examined through the characterization of polymorphisms based on gene frequencies of SNP and EST-SSR loci. The results demonstrated that the number of alleles (N), observed heterozygosity (Ho), expected heterozygosity (He), and polymorphism information content (PIC) gradually decreased with the increase of inbreeding generations. The genetic detection results indicated that 9 (29.03%, 9/31) of the SNP loci and 15 (32.61%, 15/46) of the EST-SSR loci were homozygous in F11 generation of EC4 inbred line. The variation of the growth-related traits, the immune responses, and antioxidant status were described in experimental full-sibling inbred populations of E. carinicauda at five levels of inbreeding coefficient (F=0.785, F=0.816, F=0.859, F=0.886, F=0.908) under controlled laboratory conditions. The body weight, body length, and survival rate in EC4 inbred line of all generations were less than the control population. Inbreeding affected the antibacterial activity, phenoloxidase (PO) activity, and superoxide dismutase (SOD) which decreased at the eleventh generation of EC4 inbred line. This study demonstrated that inbreeding had a negative effect on the economic traits and immune response, but our inbred line was established successfully until F11 and confirmed by genetic detection using SNP and EST-SSR loci.

Emerging Themes

Tourism and landscape are broad and complex scientific research fields, as is the synergy between them has given rise to a volume of articles diverse in nature, subject matter and methodology. These difficulties mean that, at present, there is no complete theoretical framework to support this tourism and landscape research, nor complete knowledge of its structure and organization. This motivates the present work, which constitutes the first attempt at mapping this research topic by applying bibliometric techniques using VOSviewer and Science Mapping Analysis Software Tool (SciMAT) software. A total of 3340 articles from journals indexed in Web of Science were analyzed. The results obtained confirm that interest in the study of these concepts has been growing, especially in the last decade. The main contribution of this work lies in the identification of work themes that were basic to the construction of the field but that are currently in decline, such as “cultural heritage” and other themes important to the field that should continue to be dealt with, such as “national parks” or “geotourism”. The transversal nature of sustainability that appears in the network of keywords related to currently emerging themes, such as “planning” and “environment”, is also highlighted and reinforced.

Customers Perspective

AbstractReturns are an inconvenient problem in the mail-order business, not only for the merchant but also for the customer. With an estimated return rate of 50% in the fashion sector, the seller has to deal with the expense of restocking and possibly reprocessing, the buyer, who must reship the return, and the environment. We do not consider returns to be generally bad, but rather an explicit, integral part of the online business model. Therefore, we investigate potentially suitable measures to avert or avoid returns in the pre-purchase, purchase, and post-purchase phases. We look at current and technological developments in return management and the most critical drivers for fashion assortment returns. The measures we investigate deliver a holistic view of the issue and target all three purchase phases. The resulting measures were assessed via an online questionnaire with 8393 participants (customers of a German fashion online retailer) to impact customer satisfaction using Kano’s method. There are clear measures that promise high customer satisfaction (such as 360° view) and a clear hierarchy regarding monetary and non-monetary measures. By applying a new method, the segmented Kano perspective, we found different customer segments, which are different in their expectations towards returns. That allowed us to conclude dynamics regarding return management. This assessment is followed by discussing the results, conclusions, and indications for further research fields.
