Fertility, Family, and Human Migrations

2019

The aim of this course is to introduce students to the relationship between demographic change, economic growth, and human well-being. Nothing is more fundamental to our experience whether as individuals, as family members and in society, as death, birth, and our physical place in the world. While those basic features of human life have remained a constant feature of our existence, the nature of the economic and social forces that determine the character of these interactions have changed considerably over time. The topics covered in the course illustrate examples of how human societies have wrestled with demographic problems both in history and at present. We study these topics through an …

Upper Caraş River (Danube watershed) fish populations fragmentation – technical rehabilitation proposal

2017

Abstract We propose a technical solution for fish movement based on the flow of water over a spill threshold. Such barriers are common in the Danube system. The proposed system has a range of operating components which are easily detachable from the spill threshold, are resistant to corrosion and will not harm the fish. In fact, if designed to complement swimming abilities of target fish, it should provide adequate passage for both adults and juveniles. If implemented correctly, the design may offer a solution to help displaced fish recolonize upstream habitats.

Etnografie del contemporaneo. Una introduzione siciliana

2016

The metalessic manipulation of space / time and its chronological relationships, the construction of competitive narratives between local and global, that according to the dominant rhetoric would produce unequivocal locality, defined in its relational and contextual aspects, are at the base of the "neo modern" society "Which becomes a field of cultural contestation and construction of the ethnorami of the neighborhood. The locality is a historical product and "the stories through which the localities emerge are eventually subject to the dynamics of the global" 9.

Determination of 60 Migrant Substances in Plastic Food Contact Materials by Vortex-Assisted Liquid-Liquid Extraction and GC-Q-Orbitrap HRMS

2021

A GC-HRMS analytical method for the determination of 60 migrant substances, including aldehydes, ketones, phthalates and other plasticizers, phenol derivatives, acrylates, and methacrylates, in plastic food contact materials (FCM) has been developed and validated. The proposed method includes migration tests, according to Commission Regulation (EU) 10/2011, using four food simulants (A, B, C, and D1), followed by vortex-assisted liquid–liquid extraction (VA-LLE) and GC-Q-Orbitrap HRMS analysis in selected ion monitoring (SIM) mode, with a resolving power of 30,000 FWHM and a mass accuracy ≤5 ppm. The method was validated, showing satisfactory linearity (R2 ≥ 0.98 from 40 to 400 …

Tracking migration of black‐headed buntings Emberiza melanocephala reveals the Iranian Plateau as an ecological barrier along the Indo‐European flyway

2021

The black-headed bunting is one of the few species that migrate along the Indo-European flyway, and its migration routes and phenology are poorly understood. We provide the first individual-based year-round tracking study describing route choice and timing of black-headed buntings migrating from a breeding site in Croatia to a 6000 km distant non-breeding region in Maharashtra, central India. To evaluate landscapes important for the black-headed bunting migration, we quantified land covers and climates along the migration corridor. Stopover areas during the post-breeding migration were concentrated in four distinct regions: the Balkan Peninsula, central Anatolia, along with the Zagros mount…

Diel variability in counts of reef fishes and its implications for monitoring

2006

Studies of reef fish assemblages in space rarely consider the effects of temporal variability on spatial comparisons, and when they do, usually examine timescales of months to years. The nature of fish monitoring surveys is such that particular locations may be surveyed at one time of day, and surveys designed to establish the degree of spatial variability in assemblages may be confounded if the order of sampling within treatments is not randomised with respect to time of day. In this study, we tested the degree of temporal variability in temperate reef fish counts at the same sites in New Zealand and Italy, within and between days. Repeated counts separated by months returned quite differe…

International Student Migration in Finland

2021

There is increasing attention on the retention of international students with many stakeholders desiring to keep international students for long-term economic growth. This study examines the factors affecting international students to stay in Finland five years after initial enrolment with particular focus on the role graduation plays in students staying or leaving. Tracking 11 (years) entering cohorts for five years across national (Finland) data registries, we found evidence of an inverse relationship between graduation, degree type, and the probability of staying; higher the degree level of graduation, the decrease in probability an international student stays. We conclude that while gra…

Intra-regional mobility of PhD students in the European Union : the outcomes of region-making policy?

2022

This paper examines the flow of intra-European Union (EU) students for doctoral (PhD) studies to identify reasons for differences in international student mobility and migration (ISM) among member states. Rather than conceptualising intra-EU PhD student ISM only through push–pull forces, we theorise the intra-EU PhD ISM is associated with relative levels of national resources or levels of capital. We investigate the intra-EU PhD ISM through dyadic country pairings allowing the use of Gravity models to estimate the effect of variables associated with stocks of capital ascribed to a country to the change in the number of PhD students. The findings of this study indicate while there is asymmet…

Habiter la jungle de Calais

2017

Mentre la politica di smantellamento dei campi di migranti continua, Éléonore Bully ripensa alle condizioni di vita nella "giungla di Calais" prima della sua distruzione nel 2016. Lei dimostra che, nonostante la precarietà dell'insediamento, le pratiche dei migranti ne hanno fatto un luogo di socievolezza e vita quotidiana dignitosa. Alors que la politique de démantèlement des campements de migrants se poursuit, Éléonore Bully revient sur les conditions d’habitat dans la « jungle de Calais » avant sa destruction en 2016. Elle montre que, malgré la précarité de l’installation, les pratiques des migrants en ont fait un lieu de sociabilité et de vie quotidienne digne.
