Art and the Body Image: about Self and Stereotypes

Today's man is socially absorbed by problematic body issues and everything that this means and involves. Literature, publicity, science, technology and medicine compound these issues in a form of this theme that has never been seen before. In the artistic framework, body image is constantly suffering modifications. Body image in sculpture unfolds itself, assuming different messages and different forms. The body is a synonym of subject, an infinite metaphorical history of our looks, desires, that leads one to interrogate his/her image and social and sexual relations. These are understood as a manifestation of individual desires freed from a moral and social imposition. It attempts a return to profound human nature before we are turned into a cloning industry. In thisstudy it isimportant for usto understand in which form doessculpture reflect body image as a sociocultural and psychological phenomenon within the coordinates of our time. To understand how they represent and what artists represent in sculpture as a multiple and complex structure of human sexuality. Today, the sculptural body, expanding its representation, no longer as a reproduction of the corporal characteristics, presents the body in what it possesses of most intimate, unique, human and real, that moves, reacts, feels, suffers and pulsates, a mirror of us all.

The Return of Institutions. On the Latest Change in the Research on Social and Economic Development

The paper describes the latest change in the research on social and economic development of states. This change is characterized mainly by a strong emphasis put on the role of institutions as key instruments of reducing the development gap between countries. It is argued that in the years after 1989 institutions have disappeared from mainstream academia and major intellectual debates because of: (1) the widespread belief in global convergence of capitalism and (2) the modernization theory which prevailed in the social science in the 1990s. The article indicates that institutions were once again brought into focus as a result of (1) a wider debate about the institutional sources of growth and development sparked by Acemoglu and Robinson’s Why Nations Fail, (2) the beginning of the global economic crisis of 2008 triggered by the fall of American investment bank Lehman Brothers (3) diversified consequences of the economic crisis seen all over Europe and the USA which illustrate (4) the institutional varieties of capitalism.

Ratios and indicators that determine return on equity

This study aims to investigate factors that may affect return on equity (ROE). The ROE is a gauge of profit generating efficiency and a strong measure of how well the management of a firm creates value for its shareholders. Firms with higher ROE typically have competitive advantages over their competitors which translates into superior returns for investors. Therefore, seems imperative to study the drivers of ROE, particularly ratios and indicators that may have considerable impact. The analysis is done on a sample of 90 largest non-financial companies which are components of NASDAQ-100 index and also on industry sector samples. The ordinary least squares method is used to find the most impactful drivers of ROE. The extended DuPont model’s components are considered as the primary factors affecting ROE. In addition, other ratios and indicators such as price to earnings, price to book and current are also incorporated. Consequently, the study uses eight ratios that are believed to have impact on ROE. According to our findings, the most relevant ratios that determine ROE are tax burden, interest burden, operating margin, asset turnover and financial leverage (extended DuPont components) regardless of industry sectors.

Searching for return: How Google search engine query data can beat the market

Throughout the last years technologic improvements have enabled internet users to analyze and retrieve data regarding Internet searches. In several fields of study this data has been used. Some authors have been using search engine query data to forecast economic variables, to detect influenza areas or to demonstrate that it is possible to capture some patterns in stock markets indexes. In this paper one investment strategy is presented using Google Trends’ weekly query data from major global stock market indexes’ constituents. The results suggest that it is indeed possible to achieve higher Info Sharpe ratios, especially for the major European stock market indexes in comparison to those provided by a buy-and-hold strategy for the period considered.

Macroeconomic rates of return of public and private investment : crowding-in and crowding-out effects

Using annual data from 14 European Union countries, plus Canada, Japan and the United States, we evaluate the macroeconomic effects of public and private investment through VAR analysis. From impulse response functions, we are able to assess the extent of crowding-in or crowding-out of both components of investment. We also compute the associated macroeconomic rates of return of public and private investment for each country. The results point mostly to the existence of positive effects of public investment and private investment on output. On the other hand, the crowding-in effects of public investment on private investment vary across countries, while the crowding-in effect of private investment on public investment is more generalised.

Pairs trading in the UK equity market: risk and return

In this paper, we provide the first comprehensive UK evidence on the profitability of the pairs trading strategy. Evidence suggests that the strategy performs well in crisis periods, so we control for both risk and liquidity to assess performance. To evaluate the effect of market frictions on the strategy, we use several estimates of transaction costs. We also present evidence on the performance of the strategy in different economic and market states. Our results show that pairs trading portfolios typically have little exposure to known equity risk factors such as market, size, value, momentum and reversal. However, a model controlling for risk and liquidity explains a far larger proportion of returns. Incorporating different assumptions about bid-ask spreads leads to reductions in performance estimates. When we allow for time-varying risk exposures, conditioned on the contemporaneous equity market return, risk-adjusted returns are generally not significantly different from zero.

Mars delivery service - development of the electro-mechanical systems of the Sample Fetch Rover for the Mars Sample Return Campaign

This thesis describes the development of the Sample Fetch Rover (SFR), studied for Mars Sample Return (MSR), an international campaign carried out in cooperation between the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). The focus of this document is the design of the electro-mechanical systems of the rover. After placing this work into the general context of robotic planetary exploration and summarising the state of the art for what concerns Mars rovers, the architecture of the Mars Sample Return Campaign is presented. A complete overview of the current SFR architecture is provided, touching upon all the main subsystems of the spacecraft. For each area, it is discussed what are the design drivers, the chosen solutions and whether they use heritage technology (in particular from the ExoMars Rover) or new developments. This research focuses on two topics of particular interest, due to their relevance for the mission and the novelty of their design: locomotion and sample acquisition, which are discussed in depth. The early SFR locomotion concepts are summarised, covering the initial trade-offs and discarded designs for higher traverse performance. Once a consolidated architecture was reached, the locomotion subsystem was developed further, defining the details of the suspension, actuators, deployment mechanisms and wheels. This technology is presented here in detail, including some key analysis and test results that support the design and demonstrate how it responds to the mission requirements. Another major electro-mechanical system developed as part of this work is the one dedicated to sample tube acquisition. The concept of operations of this machinery was defined to be robust against the unknown conditions that characterise the mission. The design process led to a highly automated robotic system which is described here in its main components: vision system, robotic arm and tube storage.

L’efficacia del protocollo di Askling nel return to play del calciatore post lesione muscolare agli Hamstring: revisione sistematica della letteratura

Background: Gli infortuni muscolari generano grande preoccupazione nella medicina sportiva e costituiscono la più frequente causa di assenza dal campo nel calcio. Nello specifico , a causa dei gesti tecnici caratteristici di questo sport, le HSI (lesioni muscolari agli Hamstring) sono le più frequenti nei calciatori, costringendoli all’assenza dal campo più di qualsiasi altro infortunio. Il protocollo di Askling è uno degli studi più popolari e riconosciuti nella riabilitazione delle HSI. Obiettivi: L’obiettivo della revisione sistematica è valutare l’efficacia del protocollo di Askling nel RTP del calciatore post lesione muscolare agli Hamstring. Questo contributo, quindi, discuterà gli attuali concetti clinici riguardanti la riabilitazione delle HSI, analizzando trial clinici randomizzati che confrontino gli effetti del protocollo di Askling con altri protocolli.

 Materiali e Metodi: Nella selezione degli articoli, sono state indagate le seguenti banche dati: “PubMed”, “PEDro” e “Cochrane Library”. Una volta realizzato il PICOS, questo è stato convertito nelle parole chiave pertinenti all’argomento di interesse della revisione. Sono stati presi in esame unicamente studi RCTs, di qualsiasi anno di pubblicazione e lingua, reperibili in modalità Full Text attraverso il servizio proxy offerto dall’Università di Bologna. Gli studi per essere inclusi devono avere un punteggio PEDro score > 5. Risultati: Il tempo medio del Return To Play è stato ridotto di 23 giorni, da 51 (C-Protocol) a 28 giorni (L-Protocol). Non vi è però alcuna differenza significativa tra i gruppi per i tassi di re-injury entro 2 mesi, da 2 a 6 mesi e da 6 a 12 mesi.
 Conclusioni: Emerge dalla letteratura che un protocollo riabilitativo costituito principalmente da esercizi che prediligono l’allungamento muscolare risulta più efficace di un protocollo convenzionale nel ridurre il tempo trascorso dall'infortunio all'allenamento completo senza restrizioni e/o al match play.

Modelli Stocastici per la valutazione di un Total Return Swap

L’obiettivo del presente lavoro di tesi è quello di derivare la valutazione di un Total Return Swap (TRS) utilizzando la modellistica stocastica che sta alla base dello studio del pricing di derivati finanziari. I contratti di tipo swap, la cui origine è collocata intorno agli anni ’70, prevedono lo scambio di flussi tra due parti, definiti sulla base del sottostante. In particolare, un Total Return Swap è un derivato finanziario che prevede lo scambio periodico di pagamenti definiti rispetto alla gamba di performance del sottostante e alla gamba di interesse. L’elaborato è composto da un’introduzione alle nozioni matematiche preliminari alla costruzione di un modello di mercato utile a derivare il pricing di un derivato (i.e. Teoria di non arbitraggio, esistenza di una misura martingala e le condizioni sotto le quali questa è unica). Nel secondo capitolo, vengono presentate le definizioni finanziarie necessarie alla descrizione di tali prodotti (e.g. Tassi d’interesse spot e Tassi forward). Nel corso della tesi viene presentata una rassegna della modellistica per l’evoluzione dei tassi descritti da dinamiche di volta in volta più complesse, e.g. Modello di Vasicek, modello di Dothan e approccio di Heath-Jarrow-Morton (HJM). In tale contesto, sono state derivate le formule di valutazione ad Accrual e a Net Present Value (NPV) per il TRS sfruttando la teoria di non arbitraggio, la cui principale differenza diviene dal considerare o meno l’attualizzazione tramite il fattore di sconto stocastico dei flussi di cassa previsti tra le due parti del contratto. Nell’ultimo capitolo, viene presentata un’analisi delle due modalità di pricing effettuata su due TRS rispettivamente su basket di azioni e basket di indici.
