uando el famoso modisto parisiense Paul Poiret abandonó los corsés y el estilo abullonado de la Belle Époque en favor de una apariencia más esbelta y ágil, inspirado en parte por las bailarinas de los ballets rusos, se produjo una revolución de la moda que tuvo muchas
consecuencias inesperadas. Abandonar los rellenos parecía un golpe a favor de la libertad del sexo femenino. Por otra parte, como diría la robusta soprano Frances Alda en sus memorias Hombres,
mujeres y tenores, las dietas y el ejercicio se volvieron parte de la rutina diaria de las mujeres que
deseaban mantenerse en forma y a la moda. En 1920, el deporte se volvió sexy. Por primera vez las mujeres deportistas, como la tenista Suzanne Leng, seis veces campeona en Wimbledon, se volvieron modelos de conducta para otras mujeres.
Los atuendos adecuados para el esquí, la equitación y el tenis dominaban las páginas de las revistas de moda. Esta elegante esquiadora que parece ser un autorretrato con cabello oscuro, fue pintado para la portada de la revista de modas alemana Die Dame.
This analysis of a borderline case in the threshold of the depressive position was written one year after the publication ofMelanie Klein’s “Envy and Gratitude” (1957) and is an application of the theory of envy and a study of splitting processes through projective identification With clinical material from one week of a young man’s analysis, the author shows how the reconstruction of good internal objects and a surge towards the integration of the ego is intimately linked to the danger of fragmentation of the ego and objects.
This brief clinical paper sets out to demonstrate a critical week in the third year of the analysis of a borderline schizoid case. The material represents the culmination of certain lines of work during the previous year aimed at demonstrating psychic reality to the patient but also stands as the beginning of a period of six months characterized by marked clinical improvement outside the analysis and the most dogged resistance to any further advance within the consulting-room.
In this chapter, you will learn about and use the new features in C#
2.0, including generics, iterators, anonymous methods, partial types, static classes, nullable types, and limiting access to properties, as well
as delegate covariance and contravariance.
Probably the most exciting and most anticipated new feature in
C# 2.0 is generics, which provide you with quick and easy
type-safe collections. So, let's start there.
Type safety is the key to creating code that's easy to maintain. A type-safe language (and framework) finds bugs at compile
time (reliably) rather than at runtime (usually after you've shipped the
product!). The key weakness in C# 1.x was the absence of generics , which enable you to declare a general collection (for
example, a stack or a list) that can accept members of any type yet will
be type-safe at compile time.
In Version 1.x of the framework, nearly all the collections were
declared to hold instances of System.Object, and because
everything derives from System.Object, these collections could hold
any type at all; that is, they were not type-safe.
Remote Method Invocation (RMI) framework is a powerful, easy-to-use,
and robust framework for building distributed applications.
Its ideal for a wide variety of mid-range
applications that dont fit into the Enterprise
JavaBean (EJB) model, dont require the
cross-language capabilities of either CORBA or web services, and
dont use a web browser for a client.
RMIs ease of use is legendary. But ease of use gets
you only so far. In this chapter, I will outline a number of best
practices that will enable you to take an ordinary RMI application
and turn it into one that performs well, is easy to maintain, and
will be useful for years to come.
Because of space considerations, Ive chosen to
focus on three basic areas: marshalling and unmarshalling objects,
making applications more robust, and improving application
is a generic term for gathering data
from one process and converting it into a format that can be used
either for storage or for transmission to another process
(correspondingly, unmarshalling involves
taking the converted data and recreating the objects). In RMI,
marshalling is done either via serialization or externalization.
Marshalling and unmarshalling occupy a strange role in designing a
distributed application. On the one hand, the means by which you
perform marshalling and unmarshalling is a technical detail: once
youve decided to send information to another
process, how you do so shouldnt be a primary design
consideration. On the other hand, its a very
important technical detail, and the way you do it can often make or
break an application.
