Passing the test of motherhood? Self‐esteem development and birth experience in the transition to motherhood : A longitudinal mixed methods study in …
2022
Aims To investigate women's childbirth experiences and their relation to self-esteem development in the postpartum year. Design A mixed methods study. Methods Women (N = 125) completed survey questionnaires regarding their self-esteem and childbirth experiences at three time points in 2020–2021: third trimester of pregnancy (T1), 4–8 weeks postpartum (T2) and 1 year postpartum (T3). The survey results were analysed using qualitative thematic and quantitative path analyses with latent change factors. The open-ended answers of the women who demonstrated a change in self-esteem between T2 and T3 were then compared. The STROBE checklist was used as the reporting guideline. Results The quantitat…
Synthesis and Structure-Affinity Relationships of Spirocyclic Benzopyrans with Exocyclic Amino Moiety
2019
σ1 and/or σ2 receptors play a crucial role in pathological conditions such as pain, neurodegenerative disorders, and cancer. A set of spirocyclic cyclohexanes with diverse O-heterocycles and amino moieties (general structure III) was prepared and pharmacologically evaluated. In structure-activity relationships studies, the σ1 receptor affinity and σ1:σ2 selectivity were correlated with the stereochemistry, the kind and substitution pattern of the O-heterocycle, and the substituents at the exocyclic amino moiety. cis-configured 2-benzopyran cis-11b bearing a methoxy group and a tertiary cyclohexylmethylamino moiety showed the highest σ1 affinity ( Ki = 1.9 nM) of this series of compounds. In…
Ku teorii recytacji. Interdyscyplinarny charakter badań nad sztuką recytacji
2016
Artykuł zawiera przegląd stanowisk badawczych w odniesieniu do sztuki recytacji. Autorka wskazuje na recytację jako na zjawisko, którego rozumienie wymaga podejścia interdyscyplinarnego, uwzględniającego punkty widzenia wielu dyscyplin badawczych, jak chociażby językoznawstwa, literaturoznawstwa, teatrologii oraz estetyki. W perspektywie badawczej tych dwóch pierwszych dyscyplin recytacja ukazuje się jako sztuka wykonawcza, sztuka interpretacji zależna od literackiego tekstu. Perspektywa teatrologiczna z kolei ukazuje recytację w odniesieniu do teatru i sztuki aktorskiej. Jeżeli recytacja jest częścią mówienia scenicznego, to nie należy jej przeciwstawiać sztuce aktorskiej, lecz uznać, iż d…
Research literature clustering using diffusion maps
2013
We apply the knowledge discovery process to the mapping of current topics in a particular field of science. We are interested in how articles form clusters and what are the contents of the found clusters. A framework involving web scraping, keyword extraction, dimensionality reduction and clustering using the diffusion map algorithm is presented. We use publicly available information about articles in high-impact journals. The method should be of use to practitioners or scientists who want to overview recent research in a field of science. As a case study, we map the topics in data mining literature in the year 2011. peerReviewed
Bilevel heat exchanger network synthesis with an interactive multi-objective optimization method
2012
Abstract Heat exchanger network synthesis (HENS) has been an active research area for more than 40 years because well-designed heat exchanger networks enable heat recovery in process industries in an energy- and cost-efficient manner. Due to ever increasing global competition and need to decrease the harmful effects done on the environment, there still is a continuous need to improve the heat exchanger networks and their synthesizing methods. In this work we present a HENS method that combines an interactive multi-objective optimization method with a simultaneous bilevel HENS method, where the bilevel part of the method is based on grouping of process streams and building aggregate streams …
An examination of nonresponse in a study on daily family life: I do not have time to participate, but I can tell you something about our life
2012
The aim of this study was to look at the issue of nonresponse and self-selection bias in the context of a family study on daily family life. Data on the participating families and refusers were gathered as part of the wider Palette study in which questionnaires and diaries were used as data collection methods. On the basis of these data (N = 208 participating families and 119 refuser families), we profile the families left outside the study. The parents who declined to participate in the Palette study were asked to fill in a short refusal form, which included questions concerning their family background and reasons for refusal, and they were also asked to write freely about their everyday l…
Opportunity Discovery and Creation in Cloud Computing
2013
Cloud computing provides opportunities for firms selling or using cloud services. However, little is known about how entrepreneurs discover or create these opportunities for cloud computing. In this study, we found that the opportunities discovered in cloud computing were related to the development of software for a particular need. By contrast, created opportunities were developed under conditions of technological uncertainty, at a time when the market did not yet exist. It appears that created opportunities, if successful, bring long-term competitive advantages, whereas discovered opportunities are more easily copied and exploited by competitors. peerReviewed
Anticipation as Platform Power : The Temporal Structuring of Digital Everyday Life
2023
This article explores anticipation as a temporal structure in digital platforms. It contributes to the growing research of platformisation of everyday life by focusing on temporality as a central dimension of platform power, a key mechanism tying participants by structuring intimacies, socialities, and relations that platforms enable and engender. The article shows how the temporality of foreboding, prospecting and speculating about one’s own and other’s social media presence and actions permeates the user experience. Studying media diaries and interviews with participants from different social and occupational groups (politicians, actors, the unemployed, undocumented migrants), the article…
La aplicación del derecho extranjero en iberoamérica y la unión europea: : paralelismos desde la diferencia
2021
The potential application of a foreign law constitutes the logical outcome of any Private International Law? system. However, and despite its relevance, this issue lacks a common answer in the EU. In contrast to this, the analysis of the solutions drafted in Latin America as regards this issue grants a novel dimension to the European situation on this issue as well as highlights a meritorious reality that shows a high and very relevant degree of harmonization
E-Sports y brecha de género: la percepción de las profesionales españolas
2019
The present paper aims to identify the causes of under-representation of women in E-sports. According to a genre perspective, interest in videogames at the amateur level is quite similar. However, in its professional level, female participation becomes very limited. The fact that physical effort is irrelevant (a requirement for ?traditional sports?) could be considered a variable that would negatively affect greater to equality in the conditions of access and participation of women in electronic sports. Against any predictions, the data on the presence of women are elocuent: few women, with much lower wages than men to remunerate same skills, and a general complaint by the female profession…
