An intertemporal pricing model for CO2 allowances: The impact of the clean development mechanism

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Finance from the NOVA – School of Business and EconomicsThe increasing global attention to greenhouse emissions and the recent creation of EU Emission Trading Scheme has clearly suggested the need of consistent methods to value projects aimed to reduce gases. This need particularly concerns companies that have to find a way to both remain profitable and conform to new legal requirements. Multiple ways of cutting emission costs are available nowadays: short term abatement measures, which primary involve switching production machinery from coal to gas; long term abatement measures, which envisage the implementation of new types of projects .e.g Clean Development Mechanism or Joint Implementation Mechanism suggested by Kyoto Protocol -. In this work we study the impact of the introduction of both kinds of policy in a pricing model for CO2 allowances

Bonaini, Top'Ivio e il gato Archivaldo: possono gli archivi essere (anche) divertenti?

L\u2019articolo affronta il tema della promozione degli archivi in quanto problema di comunicazione alla luce soprattutto delle risorse digitali disponibili. In particolare vengono valutate le ricadute dell\u2019uso del web come strumento di comunicazione archivistica a finalit\ue0 promozionali, facendo riferimento ad alcuni esempi italiani ed internazionali che rendono disponibili risorse didattiche e di supporto alla ricerca archivistica. The article deals with the promotion activities of archives as an issue of communication, in relation also to the use of digital resources. It examines the impact of the web as a tool for \u201carchival marketing\u201d, using and comparing few examples of Italian and international archival websites with their focus on teaching archives

RENMINBI INTERNATIONALIZATION, AN INTERPRETATION OF REAL CHINA ORIENTATIONS AND POSSIBLE EFFECTS FOR HONG KONG STOCK EXCHANGE MARKET

The article is a research on Chinese Political Economy, dealing about Renminbi Internationalization and its effects on Hong Kong Stock Exchange. In the article I went through the step conducted by Chinese government to internationalize its currency. Then tried to analyze real Chinese intentions and actions, examining indexes of Hong Kong market to understand what are the effects on Hong Kong finance market. Hong Kong is an ideal stage to measure perceptions of benefits underpinned to Renminbi (RMB) internationalization. In fact Hong Kong is part of People’s Republic of China as a Special Administrative Region and benefits from this situation, having particular political and economic autonomies. In particular Hong Kong has its own currency and political economy and can deal with Chinese economy from the particular position of an external insider. Hong Kong is also the first market where have been issued bonds in Renminbi and is probably going to become the most affected economy from the internationalization. I conducted an analysis of possible real benefits (or negative effects) that Hong Kong and its population could have from an internationalized RMB taking in account effects of Chinese step toward Internationalization on Hong Kong finance market. In conducting my research I found out four steps particularly representatives of RMB internationalization, for each step I analyzed Hong Kong financial market behavior and I tried to assess the effects of a definitive RMB Internationalization. I finally tried to conclude if process has to be considered and advantage or disadvantage for Hong Kong and what could be better actions for Special Administrative Region to take in order to avoid or diminish possible negative effects of RMB Internationalization process

The article examines the issues connected to the cultural character of digital archives. Aware that the timing of maturation of a cultural nature will be long and exposed the evolution of technology aims to identify how to ensure long time preservation for cultural scope and identifies main types of users and their purpose in the use of the archive

COMMON PERCEPTION OF CHINESE COOPERATION IN AFGHANISTAN

In the article I will try to define Chinese macro-strategy in investing in Afghanistan. Then, analyzing data collected on the field with an interview, I will try to examine Afghan perception of Chinese presence. After data analysis I will try to establish if Chinese strategy is useful to the picture that China wants to show of its presence in Afghanistan and what are the possible correction for doing it more efficient

Cigarette Smoke Affects ABCAl Expression via Liver X Receptor Nuclear Translocation in Human Keratinocytes

Cutaneous tissue is the first barrier against outdoor insults. The outer most layer of the skin, the stratum corneum (SC), is formed by corneocytes embedded in a lipid matrix (cholesterol, ceramide and fatty acids). Therefore, the regulation of lipids and, in particular, of cholesterol homeostasis in the skin is of great importance. ABCA1 is a membrane transporter responsible for cholesterol efflux and plays a key role in maintaining cellular cholesterol levels. Among the many factors that have been associated with skin diseases, the environmental stressor cigarette smoke has been recently studied. In the present study, we demonstrate that ABCA1 expression in human cells (HaCaT) was increased (both mRNA and protein levels) after CS exposure. This effect was mediated by the inhibition of NFkB (aldehydes adducts formation) that allows the translocation of liver X receptor (LXR). These findings suggest that passive smoking may play a role in skin cholesterol levels and thus affect cutaneous tissues functions

Studies on the biological effects of ozone: 10. Release of factors from ozonated human platelets.

In a previous work we have shown that heparin, in the presence of ozone (O3), promotes a dose-dependent platelet aggregation, while after Ca2+ chelation with citrate, platelet aggregation is almost negligible. These results led us to think that aggregation may enhance the release of platelet components. We have here shown that indeed significantly higher amount of platelet-derived growth factor (PDGF), transforming growth factor beta1 (TGF-beta1) and interleukin-8 (IL-8) are released in a dose-dependent manner after ozonation of heparinised platelet-rich plasma samples. These findings may explain the enhanced healing of torpid ulcers in patients with chronic limb ischemia treated with O3 autohaemoteraphy (O3-AHT)
