Invoking a cartesian product structure on social states: new resolutions of Sen's and Gibbard's impossibility theorems

The purpose of this article is to introduce a Cartesian product structure into the social choice theoretical framework and to examine if new possibility results to Gibbard's and Sen's paradoxes can be developed thanks to it. We believe that a Cartesian product structure is a pertinent way to describe individual rights in the social choice theory since it discriminates the personal features comprised in each social state. First we define some conceptual and formal tools related to the Cartesian product structure. We then apply these notions to Gibbard's paradox and to Sen's impossibility of a Paretian liberal. Finally we compare the advantages of our approach to other solutions proposed in the literature for both impossibility theorems.

Brazilian strepsiptera (Insecta) parasitizing vespidae, with the description of three new species of Xenos rossius, 1793 (Stylopidae)

Num lote de 10 vespas, estilopizadas, gentilmente cedidas para estudo pelo Dr. R. L. Araujo, de S. Paulo, os A. A., identificaram 5 espécies do gênero Xenos Rossius (Família Stylopidae): Xenos bohlsi Hoffmann, descrita do Paraguai e Xenos bonairensis Brèthes, descrita da Argentina, e 3 consideradas novas, que são aqui descritas.

A new species of Pseudoxenus Saunders, 1872, and a new record of Myrmecolax Incautus Oliveira & Kogan, 1959: (Strepsiptera, Insecta)

Os A. A. descrevem Pseudoxenus inclusus sp. n., baseados em uma fêmea e centenas de triungulinideos, encontrados parasitando Ammophila sp., proveniente de Corrego do Itá, Espírito Santo, Brasil. O encontro de um outro exemplar de Myrmecolax incautus Oliveira & Kogan, 1959, permitiu aos AA. complementar a descrição desta espécie, cujo holótipo está muito danificado.

The Paranuclear corpuscles in poikilothermic vertebrates: description of a new species of Pirhemocyton in Iguana iguana of Venezuela, with remarks on the nature of these organisms and their relation to applied parasites

This paper discusses the relations between the genera Toddia and Pirhemocyton, describing certain cytochemical reactions that clarify their nature, and discussing the position of these organisms as being of a parasitic or viral nature. A new species of Pirhemocyton is described form Iguana iguana from Mamo, Marapa (Dto. Federal) of Venezuela; characterized by rectangular globoids with rounded borders. Attempts at experimental infections of other genera of lizerds indicate that the new species, Pirhemocyton iguanae, is specific to the natural host, Iguana iguana. The course of the parasitemia in the lizard is described.

Two new serovars of Salmonella: S. Natal and S. potengi, isolated from fluvial water in Natal, Rio Grande do Norte State, Brazil

Two new serovars of Salmonella from estuary waters of potengi river in Natal, Rio Grande do Norte, were isolated. They were named S. natal (9,12: z4, z24:-) and S. potengi (18;z: -). Both types belong to the subgenus I, or subspecies 1, thought they showed atypical behaviour (KCN +).

Wyeomyia forcipenis, new species of mosquito (Diptera: Culicidae) from Rio de Janeiro, Brazil

Wyeomyia forcipenis sp.n. is described from specimens caught in Jacarepaguá. State of Rio de Janeiro, Brazil. The male genitalia and the chaetotaxy of the pupa and larva are figured. This species is close to Wy. bourrouli (Lutz, 1905), being distinguished particularly by the shape of the hind plate of the phallosome.

New measurements of energy expenditure and physical activity in chronic kidney disease.

The accurate estimation of total daily energy expenditure (TEE) in chronic kidney patients is essential to allow the provision of nutritional requirements; however, it remains a challenge to collect actual physical activity and resting energy expenditure in maintenance dialysis patients. The direct measurement of TEE by direct calorimetry or doubly labeled water cannot be used easily so that, in clinical practice, TEE is usually estimated from resting energy expenditure and physical activity. Prediction equations may also be used to estimate resting energy expenditure; however, their use has been poorly documented in dialysis patients. Recently, a new system called SenseWear Armband (BodyMedia, Pittsburgh, PA) was developed to assess TEE, but so far no data have been published in chronic kidney disease patients. The aim of this review is to describe new measurements of energy expenditure and physical activity in chronic kidney disease patients.

Culex siphanulatus, a new species of mosquito from the coast of Rio de Janeiro State, Brazil (Diptera: Culicidae)

Culex siphanulatus, sp. n. is described from specimens collected in bromeliads of the coast of Rio de Janeiro State, Brazil. The description includes illustrations of female, male genitalia and chaetotaxy of pupa and larva. This species is easily distinguished from the others of subgenus Microculex and does not belong to any of the four series proposed for the grouping of its species.

A new Culicoides of the stigmalis group (Diptera: Ceratopogonidae)

Notes are presented on the three known Neotropical species of the Culicoides stigmalis group of boodsucking midges: alvarezi Ortiz, fluviatilis (Lutz), stigmalis Wirth, and on deanei n.sp., which is described from the state of Rio de Janeiro, Brazil. A diagnosis is given for the group, as well as a key for identification and comparative phtographs of the female wings.

The new role of the mass media in the construction of sport and Olympic values

This paper was presented in the International Symposium on Toward the Creation of New-Sport Cultures, undertaken in Osaka, Japan, in January 28, 1996. The main purpose is to make an interpretation of the cultural values of sport and Olympism in contemporary society, considering the enormous influence that the media have on them.

New evidence of the real interest rate parity for OECD countries using panel unit root tests with breaks

This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q2-1998:Q4. The econometric methods applied consist of combining the use of several unit root or stationarity tests designed for panels valid under cross-section dependence and presence of multiple structural breaks. Our results strongly support the fulfillment of the weak version of the RIRP for the studied period once dependence and structural breaks are accounted for.

A new species of culex (Melanoconion) from atlantic tropical system of Souther Brazil (Diptera: Culicidae)

The male adult of Culex (Melanoconion) anoplicitus, a new species from Southern Tropical Atlantic System of Brazil, South America, is described and illustrated. Identification may be made by characteristic morphological aspects of genitalia which are peculiar to this species.
