Harmonization of Communication in Professional Setting
2020
The 21st century has introduced many changes in modern workplaces which have become multilingual and multicultural. The present paper sheds light on selected aspects of workplace discourse, revealing that backstage communication in a professional setting plays a very significant role in establishing and maintaining effective subject-bound transaction and/or interaction between the partners involved in communication. The theoretical framework of the paper is designed to consider recent contributions in professional communication research supported by some seminal theoretical writings on linguistic ecology that explore the role of language in natural interactions that occur among people worki…
Cooperative banks and reactions to the crisis: organizational models, governance, strategies
General and special education teachers’ knowledge about reading comprehension processes and instructional practices
2022
AbstractThe study investigated teachers’ knowledge of reading comprehension processes and reading comprehension instruction. The study was carried out among teachers (N = 65) in Estonia. The content analysis classified qualitative data from semi-structured interviews as quantitative data. The results showed that teachers’ content knowledge about reading comprehension processes and pedagogical knowledge of reading comprehension instruction were considerably variable yet mostly limited. Special education teachers (n = 37) mentioned a wider range of reading strategies than classroom teachers (n = 28). When describing how to support struggling readers, significant differences emerged between th…
Emigracja a proces uczenia się małżonków
2022
Wstąpienie Polski do struktur Unii Europejskiej zapoczątkowało emigrację poakcesyjną Polaków, dla której charakterystyczne było pojawienie się nowych kierunków wyjazdów emigracyjnych. Jednym z najbardziej popularnych stała się Wielka Brytania. Wyjazd emigracyjny jest wydarzeniem znaczącym w biografii człowieka i całej jego rodziny. W świetle koncepcji Agnieszki Bron (2000, 2006), wiąże się on z licznymi napięciami, ambiwalencją, poczuciem bezradności i zawieszenia (tzw. floating), a jednocześnie jest wydarzeniem o potencjale edukacyjnym. Celem badań uczyniono wyjaśnienie procesu uczenia się małżonków doświadczających emigracji. Przeprowadzono badania biograficzne z wykorzystaniem autobiogra…
Understanding the price drivers of successful apps in the mobile app market
2016
In this paper, we take the perspective of app developers. Specifically, based on a sample of top paid apps from three major app stores, i.e., App Store, Google Play, and Blackberry World, we construct a hedonic price model to examine the role of relevant factors in price formation in the app market. Our results suggest a strong evidence of two-sided market effects. In fact, the lower price charged for apps operating as two-sided markets reflect the strategy of subsidising users, due to the positive cross-side externalities they exert on valuable third parties. Surprisingly, the effects of trialability, in-app purchase and mechanisms to build reputation are not significant in the context of …
Data from: The influence of slavemaking lifestyle, caste and sex on chemical profiles in Temnothorax ants: insights into the evolution of cuticular h…
2016
Chemical communication is central for the formation and maintenance of insect societies. Generally, social insects only allow nest-mates into their colony, which are recognized by their cuticular hydrocarbons (CHCs). Social parasites, which exploit insect societies, are selected to circumvent host recognition. Here, we studied whether chemical strategies to reduce recognition evolved convergently in slavemaking ants, and whether they extend to workers, queens and males alike. We studied CHCs of three social parasites and their related hosts to investigate whether the parasitic lifestyle selects for specific chemical traits that reduce host recognition. Slavemaker profiles were characterized…
Data from: Macro- and microgeographic genetic structure in an ant species with alternative reproductive tactics in sexuals
2011
The genetic structure of social insect populations is influenced by their social organisation and dispersal modes. The ant Hypoponera opacior shows diverse reproductive behaviours with regular cycles of outbreeding via winged sexuals and inbreeding via within-nest mating wingless sexuals that reproduce by budding. This unusual life cycle should be reflected in the genetic population structure and we studied this on different scales using microsatellites. On a macrogeographic scale, populations were considerably structured and migration rates within the Chiricahuas were higher than those in-between mountain ranges. On a local scale, our analyses revealed population viscosity through dependan…
Data from: The evolutionary dynamics of adaptive virginity, sex-allocation and altruistic helping in haplodiploid animals
2017
In haplodiploids, females can produce sons from unfertilized eggs without mating. However, virgin reproduction is usually considered to be a result of a failure to mate, rather than an adaptation. Here we build an analytical model for evolution of virgin reproduction, sex-allocation, and altruistic female helping in haplodiploid taxa. We show that when mating is costly (e.g. when mating increases predation risk), virginity can evolve as an adaptive female reproductive strategy. Furthermore, adaptive virginity results in strongly divergent sex-ratios in mated and virgin queen nests (‘split sex ratios’), which promotes the evolution of altruistic helping by daughters in mated queen nests. How…
Un ecosistema malalt: la lluita contra la resistència a antibiòtics des d’una perspectiva global
2013
La produccio antropogenica d'antibiotics ha provocat una malaltia dels ecosistemes microbians de dimensio planetaria, la repercussio mes immediata de la qual per a l'home es la intractabilitat de les infeccions. La comprensio del fenomen i les possibilitats d'intervencio requereixen nous metodes conceptuals, analitics i tecnologics.
