Groups' warmth is a personal matter: Understanding consensus on stereotype dimensions reconciles adversarial models of social evaluation
2020
Abstract As proponents of two theories of social evaluation, we disagree whether people spontaneously differentiate societal groups' conservative-progressive beliefs (distinct claim of the agency-beliefs-communion or ABC model) or warmth/communion (distinct claim of the stereotype content model or SCM). Our adversarial collaboration provides one way to resolve this debate. Examining people from four continents who differentiated groups in their country (N = 2356), we found lower consensus on groups' warmth/communion compared to agency/~competence and beliefs (Studies 1–4). Consensus on groups' warmth/communion was lower because people differed in self-rated agency and beliefs, and they infe…
Validation study of an evaluation scale of ‘perceived social justice’ in the primary and secondary education
2018
La evaluación educativa se ha basado fundamentalmente en el éxito académico. Sin embargo, estudios recientes han valorado estudiar la percepción que el propio alumnado tiene sobre otros aspectos como, por ejemplo, el de la justicia social. Así pues, el objetivo general de nuestro trabajo es el diseño de un instrumento que permita evaluar la percepción que crea el alumnado sobre justicia social educativa (JSP-E) a partir de las interacciones y relaciones que se establecen entre alumnado y profesorado. El constructo “Justicia Social Percibida en la Educación" se incluye dentro de la dimensión de equidad del modelo de evaluación de instituciones y sistemas educativos definido en Jornet (2012) …
RIE : revista de investigación educativa
2018
Se revisa la evolución, situación actual y perspectivas de las revistas de investigación sobre educación, haciendo énfasis sobre las publicadas en español. Metodología: Se utiliza la estructura de la metodología DAFO (debilidades, amenazas, fortalezas y oportunidades), que ha demostrado ser una técnica muy eficaz para analizar y formular estrategias de acción que conduzcan a la mejora de un producto o servicio. Resultados: Se identifican las principales debilidades, amenazas, fortalezas y oportunidades de las revistas de investigación en educación, señalando los elementos fundamentales, internos y externos, que influyen sobre su desarrollo y calidad. Discusión: Se presentan conclusiones sob…
Nomograph for rapid technical and economic assessment of solar thermal systems for DHW production
2012
Abstract Different types of tools, software and empirical methods to size and assess the performance of solar thermal systems are available today. A quick and easy-to-use graphical tool is proposed here. It is based on a single diagram, called a nomograph, which embeds technical and economic information, allowing the optimisation of the size and performance of a solar thermal system starting from the main input parameters, such as the specific costs of the system and the auxiliary fuel. The optimal surfaces are calculated as a function of the fuel cost through several regressions made on data from the application of the F-Chart method for a set of system configurations. The authors have fou…
WORKING CAPITAL AS AN ENTERPRISE VALUE ASSESSMENT TOOL
2019
The valuation of an entity in off-exchange transactions involves the use of different techniques. Nevertheless, none of them guarantees the most accurate result. Therefore, it is very difficult to choose one evaluation method. Both investors, corporate managers, financial professionals, portfolio managers, and securities analysts should have a basic understanding of the process of evaluating companies. To that end, professionals recommend evaluating a company’s financial reports to detect its financial position and solvency. According to the methods of financial analysis, working capital is one of the solvency ratios, which describes the value of resources that remain after the company’s cu…
Sorafenib perpetuates cellular anti-cancer effector functions by modulating the cross talk between macrophages and natural killer cells.
2012
Alternatively polarized macrophages (Mϕ) shape the microenvironment of hepatocellular carcinoma (HCC) and temper anticancer immune responses. We investigated if sorafenib alters the HCC microenvironment by restoring classical macrophage polarization and triggering tumor-directed natural killer (NK) cell responses. In vivo experiments were conducted with sorafenib (25 mg/kg)-treated C57BL/6 wildtype as well as hepatitis B virus (HBV) and lymphotoxin transgenic mice with and without HCC. Monocyte-derived Mϕ or tumor-associated macrophages (TAM) isolated from HCC tissue were treated with sorafenib (0.07-5.0 μg/mL) and cocultured with autologous NK cells. Mϕ and NK cell activation was analyzed …
Using privacy-transformed speech in the automatic speech recognition acoustic model training
2020
Automatic Speech Recognition (ASR) requires huge amounts of real user speech data to reach state-of-the-art performance. However, speech data conveys sensitive speaker attributes like identity that can be inferred and exploited for malicious purposes. Therefore, there is an interest in the collection of anonymized speech data that is processed by some voice conversion method. In this paper, we evaluate one of the voice conversion methods on Latvian speech data and also investigate if privacy-transformed data can be used to improve ASR acoustic models. Results show the effectiveness of voice conversion against state-of-the-art speaker verification models on Latvian speech and the effectivene…
Simultaneous screening and quantification of aminoglycoside antibiotics in honey using mixed-mode liquid chromatography with quadrupole time-of-fligh…
2018
An analytical method based on liquid chromatography with quadrupole time-of-flight mass spectrometry has been developed for the simultaneous determination of six aminoglycoside antibiotics in honey. The sample pretreatment included extraction with aqueous trichloroacetic acid followed by solid-phase extraction on Strata-X polymeric reversed phase cartridges. Liquid chromatography separation was performed on an Obelisc R zwitterionic type mixed-mode column. An ionBooster™ heated electrospray source was used and showed enhanced ionization efficiency in comparison to a conventional electrospray source. The observed signal enhancement ranged from 3- (neomycin) to 16-fold (gentamicin C1). A data…
Genetic contribution in sporadic thoracic aortic aneurysm? Emerging evidence of genetic variants related to TLR-4-mediated signaling pathway as risk …
2015
Abstract Sporadic thoracic aortic aneurysms (TAA) and dissections are one of the major causes of morbidity and mortality worldwide, especially in those older than 65 years. The presentation of TAA is varied and often silent. Thus, sporadic TAA detection is often fortuitous, with identification occurring during a routine physical examination or during an unrelated medical evaluation. Once suspected, confirmation by imaging clinical approaches is needed to allow the choose of the unique treatments for TAA, namely the surgery procedures, including elective surgery or endovascular repair before the onset of catastrophic and fatal complications, such as dissection or rupture. At present, there a…
Investing in Sports Facilities: The Italian Situation Toward an Olympic Perspective. Confidence Intervals for the Financial Analysis of Pools
2015
Given the current economic crisis, there is a lack of investments also for public sport facilities, which are vital to the urban quality of the city and the quality of life of its citizens. The situation is serious in Italy, especially after the failure of public policies for funding of major events (World Cup, 1990; Winter Olympics, 2006). Some recent laws (147/2013) have revived the sector with particular atten-tion to the medium size facilities but have neglected the small structures that represent the basic activities. In case of the latter, a convergence of objectives is needed between public administrations and private investors. Therefore, public au-thorities should think in terms of…
