EVALUATING THE EFFICIENCY PROGRESS WITH TECHNOLOGY IN A SPANISH HOTEL CHAIN

ABSTRACTThis paper analyzes the changes in the total factor productivity index of a Spanish hotel chain in the period from 2007 to 2010 with the purpose of identifying efficiency patterns for the chain in a period of financial crisis. The data envelopment analysis (DEA) Malmquist productivity index was used to estimate productivity change in 38 hotels of the AC chain. Results reveal AC hotels' efficiency trends and, therefore, their competitiveness in the recession period; they also show the changes experienced in these hotels' total productivity and its components: technological and efficiency changes. Positive efficiency changes were due to positive technical efficiency rather than technological efficiency. The recession period certainly influenced the performance of AC Hotels, which focused on organizational changes rather than investing in technology.

A blockmodel study of managerial hierarchies, verbal networks, and organizational culture in four hospitals

This study demonstrates and applies a social network methodology for studying the dynamics of hierarchies in organizations. Social network (blockmodel) analysis of verbal networks in four hospitals contrasted hierarchical and structurally equivalent partitions of the sociomatrices of frequent ties and perceptions of organizational culture. It was found that the verbal networks in these organizations follow a center periphery pattern rather than a hierarchical logic and that perceptions of culture vary more by verbal network than by formal hierarchy. The perceptions of culture of central groups in one organization are much like those of peripheral groups in another. In all four hospitals, structurally equivalent social networks are more important in predicting subcultures than are hierarchical groupings and hierarchy has a limited impact on the development of verbal networks. These findings suggest the value of an amoeba rather than a pyramid metaphor in interpreting the cultures and relational structures of organizations.

A coesão de grupo dentro de uma organização

RESUMO: Na organização do tecido empresarial a sociedade contemporânea alcança o seu sucesso mediante a Coesão do Grupo. A Coesão de Grupo é hoje decisiva para qualquer organização. Um grupo começa quando as pessoas se juntam pelo desejo de pertencer a esse mesmo grupo, para ajudar e contribuir para o bem-estar dessa própria equipa. A Coesão no seio do Grupo é fundamental para se alcançarem resultados positivos. Para Weinberg e Gould (2001) “a Coesão relacionada à tarefa reflecte o grau em que os membros de um grupo trabalham juntos para alcançar objectivos comuns”. A Coesão interna aumenta se a equipa trabalha em busca dos mesmos objectivos com uma entrega total e absoluta em todo o trabalho que realizam. Quanto maior a cordialidade e a confiança transmitida e criada no meio do grupo, consequentemente maior será a Coesão e a produtividade da equipa. Com a Coesão de Grupo existe uma relação de interdependência, em termos de trabalho, nos elementos do grupo. O modelo de Coesão de Grupo acentua as semelhanças entre cada elemento e oferece também a oportunidade de participarem em todas as decisões. A Coesão de Grupo permite ainda que os membros permaneçam juntos, que os membros confiem e sejam leais uns aos outros e que também se sintam seguros. Torna-se determinante frisar que a Coesão permite que os membros se tornem influenciados pelo grupo em si, o que aumenta significativamente a satisfação dos seus membros e, à medida que o trabalho se desenvolve, que a interacção entre os membros do grupo se intensifique. Só assim se consegue provocar, manter e consolidar a Coesão dentro da organização. ABSTRACT: In the organization of business, the contemporary society achieves its success through group cohesion. The Group Cohesion is very important today, for any organization. A group begins when people come together by the desire to belong, to help and contribute to the welfare of own team. The Cohesion within a team is central to achieving positive results. To Weinberg and Gould (2001) “related to task Cohesion reflects the degree to which the group members work together to achieve common goals”. The Cohesion within the Group increases if the team works toward the same objectives, with a total and absolute in all the work they do. The greater the friendship and trust created and transmitted through the group, consequent greater Cohesion and team productivity. With the Group Cohesion there is a relationship of interdependence, in terms of labor among group members. With the group cohesion there is something similar between the group members and also the opportunity to participate in all decisions. The Cohesion of the Group allows members to stay together, that the members trust and be loyal to each other and also feel safe. I can only stress that Cohesion allows members to become influenced by the group itself, which increases the signification and satisfaction of its members, as the work develops, and that the interaction between group members to intensify. Only thus could lead to, maintain and strengthen the Cohesion within the organization.

A gestão do conhecimento na administração pública municipal em Curitiba com a aplicação do método OKA - Organizational Knowledge Assessment

O presente artigo objetiva analisar como a gestão do conhecimento se manifesta na administração pública da Prefeitura Municipal de Curitiba; para tanto, buscou-se a aplicação do método Organizational Knowledge Assessment (OKA), criado pelo Banco Mundial e organizado pela Escola Nacional de Administração Pública (Enap). No que tange aos procedimentos metodológicos, utilizou-se o estudo de caso como instrumento de pesquisa e coleta dos dados. Como resultado, identificaram-se o processo de avaliação organizacional, indicando as similaridades e distinções do desenvolvimento do método de cada área-fim, e a importância de implantar sistematicamente um processo de avaliação aliado ao planejamento da organização pública com estratégias para disseminar, compartilhar e aplicar o conhecimento produzido.

On differentiability and analyticity of positive definite functions

We derive a set of differential inequalities for positive definite functions based on previous results derived for positive definite kernels by purely algebraic methods. Our main results show that the global behavior of a smooth positive definite function is, to a large extent, determined solely by the sequence of even-order derivatives at the origin: if a single one of these vanishes then the function is constant; if they are all non-zero and satisfy a natural growth condition, the function is real-analytic and consequently extends holomorphically to a maximal horizontal strip of the complex plane.

Influence of HIV positive status on sexual behavior among males

OBJECTIVE: To compare HIV seronegative (HIV-) and HIV seropositive (HIV+) males in terms of sexual behavior with female and male partners of different types. METHOD: Cross-sectional study. From August 1994 to February 1995, a sample of 236 respondents (150 HIV- and 86 HIV+) recruited from public health centers in the State of S. Paulo (Brazil), answered a questionnaire, including questions on demographic aspects, HIV and AIDS related knowledge, sexual orientation, use of alcohol and other drugs, sexual behavior with regular and casual female and male partners, and perceived risk of HIV infection. Sexual behavior with regular and casual female and male partners within the previous three months, was investigated. RESULTS: A lower proportion of HIV+ engaged in sexual contact with regular female partners (p < .01) and in vaginal intercourse with this type of partner (p < .01). A lower proportion of HIV+ engaged in overall sexual activity (p < .001) and reported lower frequency of penetrative sexual practices (p < .05). A high level of condom use with female and male partners was identified with no significant differences being found between the two serostatus groups. Some risky sexual behavior was identified, however, especially with regular partners, suggesting that some men were continuing to practice unsafe sex. CONCLUSIONS: The high level of condom use identified suggests that safer sex advice has been taken up. Condom use was not universal, however, and some men continue to place themselves at risk, especially with regular partners. Prevention programs should strive not only to encourage HIV- to practice safer sex, but also to encourage HIV+ to do so in order to prevent further transmission of the virus.

Paleomagnetic study of the Great Foum Zguid dyke (southern Morocco): A positive contact test related to metasomatic processes

When a paleomagnetic pole is sought for in an igneous body, the host rocks should be subjected to a contact test to assure that the determined paleopole has the age of the intrusion. If the contact test is positive, it precludes the possibility that the measured magnetization is a later effect. Therefore, we investigated the variations of the remanent magnetization along cross-sections of rocks hosting the Foum Zguid dyke (southern Morocco) and the dyke itself. A positive contact test was obtained, but it is mainly related with Chemical/Crystalline Remanent Magnetization due to metasomatic processes in the host-rocks during magma intrusion and cooling, and not only with Thermo-Remanent Magnetization as ordinarily assumed in standard studies. Paleomagnetic data obtained within the dyke then reflect the Earth magnetic field during emplacement of this well-dated (196.9 +/- 1.8 Ma) intrusion.

Positive Solutions of the Dirichlet Problem for the One-dimensional Minkowski-Curvature Equation

We discuss existence and multiplicity of positive solutions of the Dirichlet problem for the quasilinear ordinary differential equation-(u' / root 1 - u'(2))' = f(t, u). Depending on the behaviour of f = f(t, s) near s = 0, we prove the existence of either one, or two, or three, or infinitely many positive solutions. In general, the positivity of f is not required. All results are obtained by reduction to an equivalent non-singular problem to which variational or topological methods apply in a classical fashion.

Positive solutions of fourth order problems with clamped beam boundary conditions

n this paper we make an exhaustive study of the fourth order linear operator u((4)) + M u coupled with the clamped beam conditions u(0) = u(1) = u'(0) = u'(1) = 0. We obtain the exact values on the real parameter M for which this operator satisfies an anti-maximum principle. Such a property is equivalent to the fact that the related Green's function is nonnegative in [0, 1] x [0, 1]. When M < 0 we obtain the best estimate by means of the spectral theory and for M > 0 we attain the optimal value by studying the oscillation properties of the solutions of the homogeneous equation u((4)) + M u = 0. By using the method of lower and upper solutions we deduce the existence of solutions for nonlinear problems coupled with this boundary conditions. (C) 2011 Elsevier Ltd. All rights reserved.

Society and technological evolution: challenges and opportunities

Starting from the assumption that, the organizational learning process influences, in a positive way, the innovative environment and that it shows positive effects on individual, group and organizational performance, this paper deals with the analysis of companies that provide knowledge-intensive products. Referring to the initial information obtained through an adequate survey that is still being performed since May 2009, the main goal is to identify the ways to an organizational learning, measure its importance and identify the effects on the social and economic development. Our reflexion study handles two Portuguese knowledge-rich-organizations, based on the metropolitan area of Lisbon. The paper has the following methodological structure: in the first chapter we will make a theoretical contextualization about the organizational learning; in the second chapter we will handle the data recovered using the SPSS statistics software and, afterwards, presenting the main results. Finally, starting from the main conclusions achieved, we willgive clues to an ongoing reflection.
