Human Trafficking for sexual exploitation in Europe. Towards a true “EU approach”?

La presente tesi analizza il reato di traffico di esseri umani in Europa, con particolare attenzione al fenomeno dello sfruttamento sessuale. La ricerca è stata condotta in parte nell’ambito del progetto “FIDUCIA. New European crimes and trust-based policy” (www.fiduciaproject.eu). La tesi è composta da 5 capitoli. Il primo capitolo introduce il reato di tratta di esseri umani, a livello globale e, successivamente, nello specifico, in Europa. Vengono presentati i fattori determinanti e le origini del fenomeno. Inoltre, ne vengono fornite le definizioni e le principali caratteristiche, in linea con i più importanti documenti internazionali sul tema. Il capitolo si chiude con una panoramica statistica, che affronta anche le criticità della raccolta di dati relativi ai reati. Il secondo capitolo analizza l’approccio correntemente adottato a livello domestico ed europeo contro la tratta. Le misure vengono presentate prima dal punto di vista teorico; successivamente ne vengono forniti esempi concreti, ad esempio convenzioni internazionali, direttive, ma anche progetti di ricerca, collaborazioni internazionali tra autorità ed ONG. Il terzo capitolo si concentra sulla tratta a fini di sfruttamento sessuale. Vengono analizzati il potenziale legame con la prostituzione, e l’approccio europeo. Segue un approfondimento dei modelli legali implementati a livello europeo ed uno studio comparato di cinque paesi membri, rappresentativi dei vari modelli di regolamentazione della prostituzione (Italia, Belgio, Polonia, Germania e Svezia). Il quarto capitolo raccoglie le interviste condotte con diversi esperti che si occupano di contrasto alla tratta: ONG italiane e straniere, referenti nazionali anti-tratta di Italia, Belgio e Germania, FRONTEX, membri del Parlamento Europeo. Nelle conclusioni, vengono proposte prima una valutazione complessiva del quadro attuale, e poi alcune raccomandazioni ai governi nazionali e agli organismi sopranazionali. In particolare, visto l’obiettivo di un contrasto omogeneo e coordinato della tratta (per sfruttamento sessuale specificamente) a livello europeo, si ritiene che un modello regolamentare uniforme della prostituzione negli stati membri possa contribuire a migliorare uniformità ad efficacia dell’approccio europeo alla tratta.

Behavioral expression of emotions and non-invasive assessment of physiological correlates in dogs (Canis familiaris)

The aim of this thesis was to validate the use of infrared thermography (IRT) to non-invasively measure emotional reactions to different situations in pet dogs (Canis familiaris). A preliminary test, aimed to evaluate the correlation between eye-temperature and rectal temperature in dog, was performed. Then, in three different situations, negative (veterinary visit), positive (palatable food rewards), and mildly stressing followed by mildly positive (separation from and reunion with the owner), variations in heat emitted from lacrimal caruncle (referred to as eye temperature) were measured with an infrared thermographic camera. In addition, heart rate and heart rate variability parameters were collected using a non-invasive heart rate monitor designed for human use and validated on dogs. All experiments were video recorded to allow behavioral coding. During the negative situation dogs’ level of activity and stress related behaviors varied across compared to the baseline and dogs showed an increase in eye temperature despite having a significant decrease in the level of activity. The positive situation was characterized by a peak in eye temperature and mean HR and dogs engaged in behaviors indicating a positive arousal, focusing on food treats and tail wagging but there were not variations in HRV during stimulation but only an increment in SDNN immediately after the stimulus. In the separation from and reunion with the owner dogs’ eye temperature and mean HR did not vary neither in the stressful nor in the positive situations, RMSSD increased after the positive episode, SDNN dropped during the two stimulations and it increased after the stimulations. During the separation from the owner dogs were mainly directed to the door or to the experimenter while during the reunion with the owner dogs were focused mainly on the owner and on the environment, exhibiting safe base effect. A different approach was used to assess the welfare of shelter dogs. Dogs were implanted with a telemeter and after implantation dogs were housed in sequence in four different situations lasting 1 week: alone, alone with toys and a stretch cot for sleeping, with an unknown, spayed, female, and alone with a daily 2-hours interaction with an experimenter. Two different approaches were tried: partially random extracted fragments from every week, behaviors from 8 a.m. to 4 p.m. were continuous during baseline and the female situation. Results showed different reactions by dogs to the different situations and interestingly not all enrichments were enjoyed by the dogs improving their welfare. Overall results suggest that IRT may represent a useful tool to investigate emotional reactions in dogs. Nevertheless, further research is needed to establish the specificity and sensivity of IRT in this context and to assess how different dogs’ characteristics, breed, previous experience and the valence and arousal elicited by the stimulus could influence the magnitude and type of the response. The role of HRV in understanding emotional valence and the one of telemeters in understanding long-term effects on sheltered dogs’ welfare is also discussed.
