Nicola Andria et les origines de la psychiatrie moderne Une contribution historiographique
No full textFrFrancesco Nicola Maria Andria (Massafra – 1747; Naples – 1814), auteur malheureusement presque complètement inconnu aujourd’hui, déploya son activité de professeur à l’Université de Naples, occupant divers enseignements: Histoire Naturelle, Médecine Théorique et Pratique, Pathologie, Agriculture. Il publie des oeuvres appréciées et examinées dans diverses parties d’Europe. En Andria, recherche et didactique s’inscrit dans un seul projet de re-fondation de la science médicale, que le «philosophe de Parthénope» méditait dès le commencement: former la nouvelle génération des médecins philosophes était partie intégrant de ce plan ambitieux. Nous avons besoin d’une médicine qui soit philosophique en combinant les résultats des recherches dans les domaines des différentes disciplines dont elle se sert, à orienter les efforts vers un but unique: l’homme est «l’oeuvre la plus merveilleuse de la main de l’Omnipotent», «convertie en une machine matérielle», principalement par le réductionnisme mécaniste. C’est pourquoi, si le but de la science est celui de protéger l’homme (voici la grande nouveauté de Andria), objectif principal semble être la pratique d’une médicine ni chimique, ni mécanique, mais d’une médicine “à l’èchelle humaine”, morale dans le traitement de ces patients qui souffrent de troubles mentaux. En Andria, la pathogénie de ces troubles est certainement organique, mais peut aussi s’enraciner dans des raisons psycho-émotionnelles. Il devient, donc, promoteur d’une thérapie morale comme moderne psychothérapie. Il insiste sur les avantages que la “médicine gentille” peut ammener aux patients, dont «aliénations mentales» peuvent être traitées avec methodus, à partir de ceux qu’on appellerait aujourd’hui les données anamnestiques; c’est à dire les souvenirs, principalement de l’enfance et des relations familiales, ainsi que les relations scolaires dans l’enfant.EnFrancesco Nicola Maria Andria (Massafra – 1747; Naples – 1814), author unfortunatelyalmost unknown nowadays, carried out his activity of teacher at the University of Naples, holding various subject: Natural History, Theoretical and Practical Medicine, Pathology, Agriculture. He published works, which were appreciated and reviewed in different parts of Europe. In Andria, investigation and teaching are inscribed in a unique project of medical science re-foundation, which the «philosopher of Partenope» meditated from the beginning: forming the new generation of medical philosophers was an integral part of this ambitious plan. It’s needed a medicine which is philosophical in combining the results of investigations in the areas of the several disciplines he uses, in addressing the efforts towards a unique end: the man is «the most wonderful Work from the hand of the Almighty», «converted in a material machine», mainly by the mechanistic reductionism. So that, if the aim of science is to protect the man (here stands the great Andria’s innovation), the main aim appears to be the practice of a medicine neither chemical nor mechanical, but a medicine “on a human scale”, moral in treating those patients suffering from mental disorders. In Andria, the pathogenesis of such disorders is certainly organic, but may also be rooted in psycho-emotional reasons. Hence, he becomes the promoter of a moral therapy as a modern psychotherapy. He insists on the advantages that the “kind medicine” may bring to patients, whose «mental alienations» can be treated with methodus, starting from those we would define today as anamnestic data, the memories, mainly of childhood and family relationships, besides the school relationships in the child.ItFrancesco Nicola Maria Andria (Massafra – 1747; Napoli – 1814), autore purtroppo oggi quasi del tutto sconosciuto, svolse la sua attività di cattedratico presso l’Università di Napoli, ricoprendo vari insegnamenti: Storia Naturale, Medicina Teoretica e Pratica, Patologia, Agricoltura. Pubblicò opere apprezzate e recensite in varie parti d’Europa. In Andria, ricerca e didattica s’inscrivono in un unico progetto di ri-fondazione della scienza medica, che il «filosofo di Partenope» meditò fin dall’inizio: formare la nuova generazione dei medici filosofi era parte integrante di questo ambizioso disegno. Occorre una medicina che sia filosofica nel coniugare i risultati delle ricerche negli ambiti delle varie discipline di cui si serve, nel dirigere gli sforzi verso un fine unico: l’uomo è «l’Opera più stupenda della mano dell’Onnipotente», «convertita in una macchina materiale», principalmente dal riduzionismo meccanicistico. Ragion per cui, se scopo della scienza è tutelare l’uomo (qui è la grande novità dell’Andria), obiettivo primario risulta essere la pratica di una medicina né chimica, né meccanica, ma di una medicina “a misura d’uomo”, morale nel curare quei pazienti che soffrono di disturbi mentali. In Andria, la patogenesi di questi disturbi è certamente di carattere organico, ma può altresì radicarsi in ragioni psicoemotive. Egli si fa quindi promotore di una terapia morale quale moderna psicoterapia. Insiste sui vantaggi che la “medicina gentile” può recare ai pazienti, le cui «alienazioni mentali» sono curabili con methodus, a partire da quelli che oggi diremmo i dati anamnestici e cioè i ricordi, principalmente dell’infanzia e delle relazioni familiari, oltreché nel bambino di quelle scolastiche

Models for Forest Growth and Mortality: Linking Demography to Competition and Climate
No full textThe Earth’s forests are of great economic, ecological, and social importance, and
sustaining them is paramount for mitigating climate change. To successfully sus-
tain forests we must understand their internal demographic dynamics and their
relationship to climate. In this thesis, I developed methods for investigating forest
dynamics and understanding their relationship to climate. I applied these methods
to data from the Alberta boreal forest and the oak forests of the Eastern United
States. First, dendrochronological methods were used to develop a retrospective
data set from the Alberta mixedwood boreal. This data was used to estimate white
spruce mortality and construct mortality models based on either recent growth or
competition. Both models classify dead or live spruce with 75% accuracy, indi-
cating the potential of using more easily available competition data. Second, I
developed a quantitative approach for predicting Alberta mixedwood demogra-
phy as a function of tree size and competition predictors using a size-structured
integral projection model (IPM). Two models were defined, one with competitive
structure, and one without. Model projections were tested using independent data,
and results show that the IPM with competitive structure better predicts annual
size distribution. Implementation of the IPM presents technical challenges: IPMs
must be numerically discretized, and the choice of integration scheme may lead to
accuracy or efficiency loss. I analyzed several quadrature schemes for representa-
tive IPMs in the third part of the thesis. Results show that the midpoint method is
often sufficient, but an Adjusted Gauss-Legendre method leads to higher accuracy.
In the final part of the thesis I considered how climate is related to annual growth
of chestnut oak in the the Eastern United States. Previously, trees growing in
closed-canopy forests were not thought to produce ring-widths useable in climate
reconstruction. However, by employing more advanced mathematical tools I used
a network of oak forests to identify a strong enough precipitation signal to extend
the current meteorological record back 150 years. My thesis illustrates the im-
portance of careful model formulation, implementation and validation in resolving
climate and competition effects in forest dynamics

No full textForest Cover Influences the Predictions Made by Species Distribution Models: A Case Study of American hazelnut (Corylus americana)
No full textSpecies distribution models can be used to predict climate impacts on biodiversity and guide conservation efforts. However, they may not fully represent biological reality when they entirely rely on climate variables alone and neglect biological interactions. My research objective is to test if including forest cover as a quantitative proxy for shrub-canopy interactions improves the predictive ability of species distribution models. My work focuses on American hazelnut (Corylus americana) as a case-study to test this framework. American hazelnut is a good candidate species because it is widely distributed throughout the eastern temperate and northern forests of North America and is likely to interact with the full gradient of 0 to 100% forest cover. The species remains understudied regarding the determinants of its distribution, despite an excellent fossil pollen record. This project used the hazelnut fossil pollen record to model the influence of canopy cover on distribution through time and to test whether hazelnut niche has been stable over time. For distribution models of American hazelnut, I found no difference in model performance when land cover variables are included at a continental extent. However, at a regional extent I found significant increases in model performance when forest cover was included. These findings suggest that land cover can more precisely define where species habitat exists at a local level compared to climate variables alone. Distribution models developed using fossil pollen occurrences and climate simulations indicate that hazelnut has maintained a consistent niche space over the past 11,000 years before present. However, the limitations of fossil pollen data created less certainty in these results. Future work involves testing this framework on additional species to determine if these patterns are consistent across woody taxa, as well as testing if land cover datasets that are more categorically resolved and include human impacts are able to improve distribution models
Potential Sources of Error and Uncertainty in Radiocarbon Dates from North American Sites
No full textRadiocarbon dating — the process of
finding the age of a material by using the
radioactive isotope carbon-14 — is an
important tool in observing and inferring
past ecological events and changes.
However, it is not without its uncertainties.
While contamination and poor treatment in
the lab can lead to larger errors, so can
mechanisms which convert the radiocarbon
age produced by the dating process into a
calendar age for scientists to use
accordingly. There are more correlations
between uncertainty and other factors —
such as age and depth — which we will
discuss in this paper.
In addition, we are using fossil
pollen sediment core data from the Neotoma
Paleoecology Database. Many of the fossil
pollen sediment cores taken were from lakes
all over North America. Not only did we use
the sediment core radiocarbon data, but we
also used the longitude and latitude of the
sites to map the area of their respective lakes
using Google Earth Pro. We then classified
the lakes as being small, medium, or large,
according to a framework used in this paper.
The dating process, along with the
lake areas, gives us an idea of when an
ecological event occurred using the
radiocarbon date produced and whether the
change was a local or a regional event using
the area of the lake. By connecting these two
parts, we gain a clearer sense of when and
where an ecological occurrence happened.
Also, by knowing the sizes of lakes,
we can evaluate the scale of ecological
change through space and time. Therefore,
ecological change can be better understood,
which would ultimately lead to improved
predictions of past changes in different
ecosystems across North Americ
Bodies of Antithesis: Gender power relations in conflict and militarized environments
No full textThe thesis aims to unveil and challenge institutionalized gender hierarchical relations between the military and women in conflict environments. It critically examines the military as an institution inherently intertwined with conflict in periods of war and during periods of conflict. The thesis argues that the military plays a significant role in shaping and maintaining gender power structures, through institutional perceptions and spatial practices. It explores the relationship between the military and women and how institutionalized gender perceptions contribute to the widening gap between them, using Cyprus as a case study. Through the use of visual ethnography as a primary methodology, the thesis seeks to shed light and challenge the oppressive prescript narratives and power dynamics imposed on women by the military.Using Nicosia and Pyla as a case study, conflict environments where inhabitants have normalized the experiences of living with the constant presence of the military, the thesis spatializes its theoretical framework. It utilizes tools and insights gained from theoretical and artistic analyses, to make visible and challenge the gender institutional perceptions, fixed gender roles, and spatialities that feed gender hierarchical structures. The ultimate goal is to expose this issue in various existing and ongoing conflict environments. Architecture, Urbanism and Building Science
