Determinants of child undernutrition in India. A micro-case study to operationalize the Capability Approach

The present research aims at shedding light on the demanding puzzle characterizing the issue of child undernutrition in India. Indeed, the so called ‘Indian development paradox’ identifies the phenomenon according to which higher level of income per capita is recorded alongside a lethargic reduction in the proportion of underweight children aged below three years. Thus, in the time period occurring from 2000 to 2005, real Gross Domestic Production per capita has annually grown at 5.4%, whereas the proportion of children who are underweight has declined from 47% to 46%, a mere one point percent. Such trend opens up the space for discussing the traditionally assumed linkage between income-poverty and undernutrition as well as food intervention as the main focus of policies designed to fight child hunger. Also, it unlocks doors for evaluating the role of an alternative economic approach aiming at explaining undernutrition, such as the Capability Approach. The Capability Approach argues for widening the informational basis to account not only for resources, but also for variables related to liberties, opportunities and autonomy in pursuing what individuals value.The econometric analysis highlights the relevance of including behavioral factors when explaining child undernutrition. In particular, the ability of the mother to move freely in the community without the need of asking permission to her husband or mother-in-law is statistically significant when included in the model, which accounts also for confounding traditional variables, such as economic wealth and food security. Also, focusing on agency, results indicates the necessity of measuring autonomy in different domains and the need of improving the measurement scale for agency data, especially with regards the domain of household duties. Finally, future research is required to investigate policy venues for increasing agency in women and in the communities they live in as viable strategy for reducing the plague of child undernutrition in India.

New associations between native parasitoids and exotic insects introduced in Italy and in Europe

The introduction of exotic species is one of the most important threats to biodiversity.This phenomenon may cause economic and environmental damage. To prevent these invasions there are institutions like EPPO. Nevertheless, the introduction of exotic pests is an increasing issue, difficult to control. Classic biological control, based on importation of natural enemies from the country of origin, has been successfully used for over 120 years, but it has also raised some criticism. My research work has focused on the study of the new associations occurring between indigenous parasitoids and three exotic pests introduced in Italy and Europe. The three target insects considered were: Cacyreus marshalli Butler (Lepidoptera: Lycaenidae), a pest of Geranium plants; Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), a plague of Castanea sp. and Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae). This ladybug has been introduced as a biological control agent, but since some years it considered as an invasive species. For C. marshalli I performed laboratory tests on acceptance and suitability of immature stages of this butterfly by Exorista larvarum (Diptera: Tachinidae) and Brachymeria tibialis (Hymenoptera: Chalcidicae). The experiments showed that these two parasitoids could be used to contain this pest. For D. kuriphilus I performed field samplings in an infested chestnut area, the samples were maintained in rearing chamber until gall wasp or parasitoids emergence. In the 3-year research many parasitoids of gall wasps were found; one of these, Torymus flavipes (Walker), was found in large number. For H. axyridis the research work included a first phase of field sampling, during which I searched indigenous parasitoids which had adapted to this new host; the only species found was Dinocampus coccinellae (Schrank) (Hymenoptera: Braconidae). Laboratory tests were performed on the wasp rearing, biology and capacity to contain H. axyridis.

La vita culturale ebraica a Candia nei secoli XIV-XVI: l'impatto dell'immigrazione sulla cultura della comunità locale

La tesi ha per oggetto la cultura ebraica cretese nei secoli XIV-XVI e, in particolare, l’influsso esercitato su di essa dalla cultura e dalle tradizioni degli ebrei sefarditi e ashkenaziti che cominciarono a stabilirsi sull’isola a partire dalla metà del Trecento. La tesi si basa da un lato su fonti amministrative e notarili e, dall’altro, sui manoscritti ebraici prodotti o portati a Candia nel periodo considerato. Il primo capitolo tratta della comunità ebraica nel primo Cinquecento e porta nuove notizie a proposito della geografia della zudeca, delle sue sinagoghe, della sua composizione sociale, dell’entità della sua popolazione e della biografia del principale leader spirituale e culturale attivo a Candia a quell’epoca: Elia Capsali. Il secondo capitolo offre una panoramica sull’immigrazione ebraica a Candia nei secoli XIV-XV. Il terzo capitolo esplora alcune particolarità della liturgia sinagogale elaborata dagli ebrei candioti sotto l’influsso della tradizione ashkenazita. Il quarto capitolo tratta di due liste di libri databili alla seconda metà del Quattrocento (Bologna, Biblioteca Universitaria, ms. 3574 B) e suggerisce di considerarle come indicative del peso che ebbero alcuni immigrati ebrei catalani nella diffusione della cultura medica sefardita a Candia. Il quinto capitolo è dedicato al medico, filosofo e astronomo Mosheh ben Yehudah Galiano, il quale visse a Candia tra la seconda metà degli anni Venti del Cinquecento e il 1543. L’ultimo capitolo tratta degli effetti provocati dall’epidemia di peste del 1592-95 all’interno della zudeca di Candia.
