The effects of land-use development policies on forest management
Cunha-e-Sá, Maria A.; Franco, Sofia F.This paper develops a model of a forest owner operating in an open-city environment, where the rent for developed land is increasing concave in nearby preserved open space and is rising over time reflecting an upward trend in households’ income. Thus, our model creates the possibility of switching from forestry to residential use at some point in the future. In addition it allows the optimal harvest length to v...
Forest management in an urbanizing landscape
Cunha-e-Sá, Maria A.; Franco, Sofia F.This paper aims at building a theoretical framework to examine the impact of development pressure on private owner’s forest management practices, namely, on regeneration and conversion cut dates. As the rent for developed land is rising over time, our model creates the possibility of switching from forestry to residential use at some point in the future, thus departing from the Faustmann’s traditional setup. Co...

Urban containment: An effective tool for environmental protection?
Cunha-e-Sá, Maria A.; Franco, Sofia F.This paper examines the effectiveness of urban containment policies to protect forestland from residential conversion and to increase the provision of forest public goods in the presence of irreversible investments and policy uncertainty. We develop a model of a single landowner that allows for switching between competing land uses (forestry and residential use) at some point in the future. Our results show tha...
The uneasy case for lower parking standards
Cutter, W. Bowman; Franco, Sofia F.Minimum parking requirements are the norm for urban and suburban development in the United States (Davidson and Dolnick (2002)). The justification for parking space requirements is that overflow parking will occupy nearby street or off-street parking. Shoup (1999) and Willson (1995) provides cases where there is reason to believe that parking space requirements have forced parcel developers to place more parkin...
Urban deforestation and urban development
Cunha-e-Sá, Maria A.; Franco, Sofia F.; Rosa, RenatoThis paper has developed a model of a single forest owner operating with perfect foresight in a dynamic open-city environment that allows for switching between alternative competing land uses (forest and urban use) at some point in the future. The model also incorporates external values of an even-aged standing forest in addition to the value of timber when it is harvested. Timber is exploited based on a multip...
Drawbacks of ovarian ablation with goserelin in women with breast cancer.
Franco, Sofia; Lupa, Paula; Guerra, Carlos; Pereira, Luís; Oliveira, Carlos F deIn the last few years, ovarian ablation with GnRH agonists has been used as first-line adjuvant therapy in pre and perimenopausal breast cancer. These drugs suppress ovarian function in the hypothalamic-pituitary axis and they have adverse effects in other end-organs. A retrospective study was conducted on 35 premenopausal women, with breast cancer, and treated with goserelin, in order to investigate the effect...
Natural history of fetal pyelocaliectasia.
Franco, Sofia; Carvalho, G; Antunes, A; Brito, M; Morais, C; Barros, J SIt is estimated that genitourinary anomalies comprise 20% of all antenatally detected fetal anomalies, and pyelocaliectasia is the most common one. Detection of antenatal dilatation of the urinary tract does not always indicate postnatal urinary tract obstruction or even a significant genitourinary anomaly. Most cases will improve spontaneously, representing a temporary physiologic impedence and do not require ...
Uterine tumor resembling ovarian sex-cord tumor.
Franco, Sofia; Andrade, M João; Silva, Teresa S; Guerra, Carlos; De Oliveira, CarlosUterine tumors resembling ovarian sex-cord tumors are rare and few cases are published in the literature. The authors describe a recently diagnosed one. The clinical features consisted of: abnormal vaginal bleeding and enlargement of the uterus, which allowed confusion with several types of uterine pathology: benign or malignant one; the diagnosis is exclusively histopathological. These tumors have a benign bio...
