WHY DID THEY NEED TO COME NOW? COVID-19 CRISIS STRAINS RELATIONSHIPS WITH RETURNING AND VISITING COMPATRIOTS
2021
One of the first areas severely hit by the Covid-19 pandemic was international travel. In March/April, with commercial flights coming to a near halt, the governments were struggling to help their stranded citizens to return home. Extra flights and ferry trips were organised, and the opportunity to return was used by many emigrants worried about the uncertainty and the possible future development of the pandemic. This paper containing both data collected through survey and in-depth interviews with people aged 50+ in Latvia, is the first to explore the reactions of the society to repatriation policy implemented by the government of Latvia, and to explore how the Covid-19 situation has affecte…
Baltijos trynukai? Emigracija, migracija ir atsakas krizei
2021
Šiame straipsnyje nagrinėjama migracijos ir ekonominio vystymosi sankirta, kaip viena aktualiausių problemų, su kuriomis susiduria Baltijos šalys. Pasinaudojus empirine prieiga, lyginami vyriausybių veiksmai esant ekonominei 2008 metų krizei. Straipsnyje analizuojama, kaip jie išryškėjo socioekonominę dinamiką atskleidžiančioje statistikoje. Tyrime taikomi lyginamosios statistikos ir antrinių duomenų analizės metodai. Visos trys valstybės patiria panašių ateities iššūkių: visuomenės senėjimas ir gyventojų skaičiaus mažėjimas, tuo tarpu emigrantų sugrįžimas matomas kaip viena iš priemonių, galinčių padėti šias problemas spręsti. Estijoje vykstantys procesai leidžia manyti, kad jos Vyriausybe…
Ecomorphological predictors of natal dispersal distances in birds.
2008
1. Dispersal is one of the key ecological parameters but it is very difficult to quantify directly. As a consequence, empirical studies often ignore dispersal or use indirect measures. 2. Ringing data have previously been used to estimate the natal dispersal distances of 47 British passerine bird species. This provides an excellent opportunity to examine the potential of various indirect measures to predict natal dispersal distances in British birds. 3. We use a phylogenetic comparative framework and single- and multipredictor models including ecomorphological, behavioural or ecological traits to predict natal dispersal distance. 4. A multipredictor model that includes Kipp's distance (a me…
Size distribution of Daphnia longispina in the vertical profile
1997
D. longispina of the meromictic lake El Tobar is a round-headed form. It never has a helmet, but in summer a small proportion of immature individuals (0.9–1.2 mm females and males) have one or two neck teeth. The size structure of this Daphnia population, as well as the vertical distribution and migration of different size-classes, were studied in September and November of 1991 and April of 1992. The large variation in mean size and size at first reproduction, as well as the occurrence of different patterns of vertical migration are interpreted as responses to different predator situations. At the end of April, when Daphnia mortality by visually hunting predators is dominating, a typical no…
Food for flight: pre-migratory dynamics of the Lesser Kestrel Falco naumanni.
2014
Capsule The post-reproductive stage of Lesser Kestrel is crucial for migratory fuelling and survival. Aims To describe the summer pre-migratory ecology of the Lesser Kestrel in Sicily and review existing data in Southern Europe. Methods We identified the main summer roosts and then made roost counts every ten days from 2010 to 2012. We used case-sensitive modelling procedures to detect biases in counts (generalized linear mixed models), assess the annual population trends from 2005 to 2012 (TRends and Indices for Monitoring); and to model habitat preferences (generalized linear model). We sampled pellets to describe the birds’ diet during the peak month prior to migration. Results We discov…
Economic Factors of Labor Migration Analysis
2021
Population of Latvia is declining every year due to rate of natural decrease and negative rate of net migration indicators [1]. It is a topical issue since it affects stability and growth of the country.
Educational Migration Trends Review in Poland (with Particular Emphasis on the Immigration of Ukrainian Youth)
2023
This article aims to review and synthesise research on educational migration in Poland, particularly youth immigration from Ukraine. The paper collects statistical data from 2004, which allowed for the analysis of the existing trends in educational migration in Poland. The research on the largest group of foreign students – citizens of Ukraine – was reviewed, which resulted in identifying research gaps regarding student mobility in Poland, both in terms of demand and supply of educational migrations. The practical implication appears to show that the governments of the host countries, the business sector, and the academic units – due to the increase in the number of foreign students – can e…
Social Inclusion and Exclusion in the Life Stories of Deported Asylum Seekers from Finland to Iraqi Kurdistan
2018
This study explores how social inclusion and exclusion manifest as a dynamic continuum in the everyday lived realities of irregular migrants. Based on narratives of Iraqi Kurdish asylum seekers, who were eventually deported from Finland, the analysis depicts the ways in which societal structures, personal negotiations as well as relationships and social networks interplay in lives characterized by multiple locations, transitions and positions. Establishing and maintaining social contacts, belonging to various networks and being able to decide and act are primary factors that help us understand how the narrators relate to the continuum. The participants construct narratives illustrating seve…
Diel feeding periodicity, daily ration and prey selectivity in juvenile brown trout in a subarctic river
1999
Feeding of age-1 brown trout Salmo trutta in a third-order river in northern Finland was usually highest in the twilight hours and lowest around midday. Diel periodicity in food intake was less distinct and rarely significant for age-0 trout. Daily rations declined seasonally, being lowest in October, and highest in June (age-1 trout) or early August (age-0 trout). Prey selection did not differ between day and night, but differences between age classes and sampling dates were distinct. Age-0 trout preferred Ephemerella nymphs in summer and Micrasema larvae later in the season. Age-1 trout fed selectively on caddis larvae on all sample dates. Aerial insects and Baetis nymphs were avoided by …
Memory for time intervals is impaired in left hemi-Parkinson patients.
2004
The basal ganglia have been proposed as one of the neural correlates of timekeeping functions. Both encoding and memory retrieval components for time perception are impaired in Parkinson's disease (PD). The aim of our study was to investigate in hemi-Parkinsonian patients the existence of a specific alteration in memory for time depending on the affected side, to better understand the contribution of the left or right basal ganglia circuits in different components of time perception. Right and left hemi-PD patients performed a time reproduction task in which they were required to reproduce in the same session short (5 s) and long (15 s) time intervals, in off- and on-therapy condition. Whil…
