Aptauja ir veikta projekta "Ekonomiskais, politiskais un juridiskais ietvars Latvijas tautsaimniecības potenciāla saglabāšanai un konkurētspējas pieauguma veicināšanai pēc pandēmijas izraisītas krīzes (reCOVery-LV)" ietvaros. Aptaujas mērķis ir novērtēt kā sabiedrība uztver valsts politikas atbilstību krīzes radītām sekām. Aptaujas rezultāti tika izmantoti zinātniskā raksta un monogrāfijas sagatavošanai.

Physiotherapists’ validating and invalidating communication before and after participating in brief cognitive functional therapy training : Test of c…
2021
Objective The aim of this study was to investigate physiotherapists’ validating and invalidating communication, before and after brief Cognitive Functional Therapy (CFT) training that included a session on validation skills. Associations between validation/invalidation and the characteristics of the interviews and physiotherapists were also explored. Methods Eighteen physiotherapists treating patients with low back pain participated in the study. The study had a within-group design in which validation and invalidation for physiotherapists were rated before and after training using a reliable observational scale. We also collected data on interview length and physiotherapists’ and patients’ …
International Assessment Surveys of Educational Achievement in Developing Countries : Why Education Economists Should Care
2015
International audience; This paper reviews the most known international assessment studies that are conducted in the context of poor countries and highlights the lack of empirical evidence on the degree to which the contents of the tests really match countries' curricula. To illustrate, the paper evaluates the sensitivity of an international testing instrument by comparing the responses of students in two consecutive grades on the same battery of tests. Using propensity score matching to control for student and teacher characteristics, the results show that the tests are not grade sensitive, which raises the question of the validity of many empirical works that are based on similar instrume…
Utility of Alternative Effect Size Statistics and the Development of a Web-Based Calculator: Shiny-AESC
2018
Alternative displays of effect size statistics can enhance the understandability and impact of validity evidence in a variety of applied settings. Arguably, the proliferation of alternative effect size statistics has been limited due to the lack of user-friendly tools to create them. Common statistical packages do not readily produce these alternative effect sizes and existing tools are outdated and inaccessible. In this paper, I introduce a free-to-use web-based calculator (https://dczhang.shinyapps.io/expectancyApp/) for generating alternative effect size displays from empirical data. This calculator requires no mathematical or programming expertise, and therefore, is ideal for academics …
Estudio de variación en el uso de atenuación I: Hacia una descripción de patrones dialectales y sociolectales de la atenuación en español
2020
Resumen La atenuación es un fenómeno pragmático de gran complejidad que se ha convertido en objeto de estudio priorizado en las últimas décadas, en las que se ha abordado, especialmente, desde disciplinas que trabajan con el habla, como la pragmática y el análisis del discurso. Uno de los aspectos menos trabajado en relación con las estrategias de atenuación en español, no obstante, es la variabilidad sociopragmática y geolectal en usos y recursos de atenuación. Este último es el cometido fundamental de este trabajo -que se complementa con la investigación presentada en el artículo de Albelda y Cestero (en este mismo volumen, 2020)-, en el que se pretende dar cuenta del estado actual de la …
The price of safety: food deprivation in early life influences the efficacy of chemical defence in an aposematic moth
2018
Aposematism is the combination of a primary signal with a secondary defence that predators must learn to associate with one another. However, variation in the level of defence, both within and between species, is very common. As secondary defences influence individual fitness, this variation in quality and quantity requires an evolutionary explanation, particularly as it may or may not correlate with variation in primary signals. The costs of defence production are expected to play a considerable role in generating this variation, yet studies of the cost of chemical defence have focused on species that sequester their defences, while studies in species that produce them de novo are scarce. …
Incidentality on a continuum: A comparative conceptualization of incidental news consumption
2020
This article seeks to contribute to theorizing the dynamics of incidental news consumption. Through an analysis of 200 semi-structured interviews with people in Argentina, Finland, Israel, Japan, and the United States, we show that intentionality in news consumption can be viewed on a continuum, which goes from deliberately setting apart time to access the news on specific outlets to skimming through unsought-for news on social and broadcast media, with intermediate practices such as respondents setting up an environment where they are more or less likely to encounter news. Drawing on structuration theory, this article conceptualizes incidental news in the context of the wider media environ…
The effects of two-way communication and chat service usage on consumer attitudes in the e-commerce retailing sector
2018
In e-commerce retailing (e-retailing), where competitors are only one click away and prices are easy to compare, providing superior customer service and reciprocal communication via a company’s website are important aspects of attracting and retaining customers. One increasingly popular solution to improve customer service is a “live chat” interface that allows consumers to have real-time conversations online with customer service agents. As the literature on the impacts of real-time communication via live chat is currently very limited, this study develops and tests a model that demonstrates the moderating effects of a chat service on the relationship between two-way communication (i.e., a…
Digital advertising around paid spaces, e-advertising industry’s revenue engine : A review and research agenda
2017
We develop and describe a framework for research in a particular segment of digital advertising. Internet Advertising Paid Slots and Spaces (IAPS) is a neologism and work almost like a stock exchange for buying and selling advertising in various formats on designated spaces around web and make a significant contribution to Internet advertising revenues. These paid spaces were found to encompass diverse areas of Internet advertising that include search engine marketing, social media advertising and display advertising. Given the complexity of the modern digital advertising eco system, this literature review seeks to provide clarity, up-to-date knowledge and ongoing insights into Internet adv…
