THE 'CYCLE OF DOING COERCION': AN ETHNOGRAPHY ON THE USE OF FORCE AND VIOLENCE IN BOTH A PRISON AND AN ASYLUM

This thesis firstly introduces the normative approach to power and Coercion on the landing selectively addressing the literatures of prison sociology, and policing . Then it presents the interactionist approach adopted. In the substantive part of the thesis it will outline the \u2018organization of the use-of-force in practice\u2019. Chapter 5 focuses on what officers do when they routinely patrol the wing, either in calm and boring situations or during more violent situations that may or may not lead to the start of what is here called and reconstructed as the \u2018Cycle of doing coercion\u2019 (that I also call the\u2019 Cycle of the use-of-force and violence\u2019 or simply \u2018the Cycle\u2019). Both Chapter 6 and 7 will instead focus on the emergency squad intervention on the wing. Lastly,Chapter 8 is methodologically oriented and deals selectively only with few relevant methodological and ethical issues that have emerged doing this particular ethnography in a custodila complex in Italy

Epitaxial growth and thermodynamic stability of SrIrO3/SrTiO3 heterostructures

Obtaining high-quality thin films of 5d transition metal oxides is essential to explore the exotic semimetallic and topological phases predicted to arise from the combination of strong electron correlations and spin-orbit coupling. Here, we show that the transport properties of SrIrO3 thin films, grown by pulsed laser deposition, can be optimized by considering the effect of laser-induced modification of the SrIrO3 target surface. We further demonstrate that bare SrIrO3 thin films are subject to degradation in air and are highly sensitive to lithographic processing. A crystalline SrTiO3 cap layer deposited in-situ is effective in preserving the film quality, allowing us to measure metallic transport behavior in films with thicknesses down to 4 unit cells. In addition, the SrTiO3 encapsulation enables the fabrication of devices such as Hall bars without altering the film properties, allowing precise (magneto)transport measurements on micro- and nanoscale devices.Comment: 5 pages, 3 figure

Insects as feed for farmed poultry: Are italian consumers ready to embrace this innovation?

The inclusion of insects as a protein source in feed production is not only related to technical, economical, and normative restrictions but is also affected by consumer acceptance. In this study, we evaluated consumers’ attitudes, intention to purchase and eat, and willingness to pay for meat obtained from a farmed duck fed with insect-based meal or a live insect diet. We conducted a survey among a sample of 565 consumers to test the effects of information about the benefits of using insects as feed on consumers’ attitudes towards animal-based products fed with insects. Providing information on the sustainability and nutritional benefits of using insects as feed increased both attitude towards and intention to purchase and eat meat products made from animals fed with insects. In the treatment group, we found a significant reduction from 21.9 to 14.0% in those who wanted to be compensated for buying a duck fed with an insect-based meal and an increase in those willing to pay the same price—from 64.9 to 72.7%. The information treatment significantly increased the intention to eat such products, suggesting that increasing consumers’ knowledge might help in reducing the fears and misconceptions around the topic of using insects as a feed source

Evaluation of carcass and meat traits of Muscovy duck fed with black soldier fly partially defatted meal

The aim of this study was to evaluate the carcass characteristics and breast meat quality in Muscovy duck (Cairina moschata domestica) fed different inclusion levels of a partially defatted black soldier fly larva (BSF) meal. A total of 256 Muscovy ducklings (average live weight, LW: 71.32\ub12.70 g) were reared from day 3 to day 48 and randomly allotted in 32 pens (8 replicates/treatment). Four different diets were formulated with increasing substitution level of corn gluten meal with BSF larva meal (0, 3, 6 and 9%; BSF0, BSF3, BSF6 and BSF9, respectively) and divided in 3 feeding phases: starter (1-14 days), grower (14-35 days) and finisher (35-48 days). At day 48, 2 animals/replicate were slaughtered and dissected to determine their carcass yields. The weights of spleen, bursa of Fabricius, liver, heart and abdominal fat were recorded. Breast and thigh muscles were then excised from 16 ducks/treatment and weighted. Ultimate pH (pHu) and L*, a*, b* colour values were then measured on breast muscle. The collected data were tested by means of oneway ANOVA evaluating the effect of dietary BSF inclusion level by polynomial contrasts. Significance was declared at P<0.05. The inclusion of BSF did not affect final LW (2,515.68\ub192.42 g on average). Hot and cold carcass weights showed a quadratic response (P<0.05) to increasing BSF larva meal, with a minimum corresponding to BSF6; however, refrigeration losses were not affected by treatments. Weight of spleen, bursa of Fabricius, liver and heart did not differ among treatments. The weight of abdominal fat showed a quadratic response to increasing BSF meal with a minimum corresponding to BSF6 group (P<0.05). Breast and thigh yields, pHu and L*, a*, b* colour values did not differ among groups. With the exception of BSF6, the inclusion of BSF meal did not affect meat traits and carcass characteristics, confirming the potential use of BSF meal in Muscovy duck diets

Apparent digestibility of insect protein meals for rainbow trout

Insect meals are considered to be promising future ingredients for aquaculture feeds. In past feeding trials in rainbow trout, insect meals were included in diets only on the basis of their nutrients content and energy density without taking into account their biological availability due to the lack of their digestible values. Apparent digestibility (ADC) provides good indication of the bioavailability of nutrients and energy thus providing rational basis for the correct inclusion of feedstuffs. The aim of this research was to assess, in an in vivo trial on rainbow trout, the ADC of five full fat insect meals: one Tenebrio molitor (TM), two Hermetia illucens obtained through two different process (HI1 and HI2), one Musca domestica (MD), and one Alphitobius diaperinus (AD). Fish were fed a high-quality reference diet (R) and test diets obtained mixing the R diet with each of the test ingredients at a ratio of 70:30. Diets contained 1% celite as inert marker. Fish were fed to visual satiety twice a day and faecal samples collected using a continuous automatic device. Faeces were freeze dried and frozen (-20 \ub0C) until analyses. The ADC of dry matter, crude protein and ether extract of each insect meal diet were calculated. ADC for dry matter varied between 70.07 (HI1) and 80.85 (TM). ADC for protein was above 84% in all treatments and resulted the highest in MD, TM and AD treatments. Ether extract apparent digestibility significantly differed among diets with the highest value reported for TM treatment. All treatments reported values higher than 96%. Observed differences could be due to the insect species and meal treatment but in general, tested insect meals were highly digestible for rainbow trout. The results from this research could be useful to optimize the diet formulation
