The perception of management accounting in the Portuguese lodging industry

The perception of management accounting (MA) in the management of Portuguese hotels is a very interesting area of research, because it is important to be aware of the needs of hoteliers. Most hotels have been changing their management, so MA has changed too. A lot of MA techniques are concerned with the preparation of specialized information. MA techniques that are currently being used by different types of Portuguese hotels have been studied, and the importance given to them was investigated. One of the conclusions of the research is that MA techniques are used in Portuguese hotels especially for decision-making. A diversified use of MA in Portuguese hotels was found. However, it should be noted that when the decisions are made with the help of the subordinates, there is a greater use of MA techniques

Schizophrenic active neutrinos and exotic sterile neutrinos

We implement a schizophrenic scenario for the active neutrinos in a model in which there are also exotic right-handed neutrinos making a model with a local U(1)_(B-L) anomaly free. Two of right-handed neutrinos carry B-L=-4 while the third one carries B-L=5.Comment: I, A. C. B. Machado, apologize for having submitted the wrong file before.

Additional symmetries and solutions of the dispersionless KP hierarchy

The dispersionless KP hierarchy is considered from the point of view of the twistor formalism. A set of explicit additional symmetries is characterized and its action on the solutions of the twistor equations is studied. A method for dealing with the twistor equations by taking advantage of hodograph type equations is proposed. This method is applied for determining the orbits of solutions satisfying reduction constraints of Gelfand--Dikii type under the action of additional symmetries.Comment: 21 page
