求解非稳定对流占优水质模型的非标准Galerkin有限元法

在求解非稳定地下水溶质运移模型时,若对流项占优,则模型表现出双曲方程的特性.针对这种特性.采用非标准Galerkin有限元方法进行求解是解决这类问题的有效途径.分别采用Wavelet-Galer-kin有限元方法、迎风有限元方法和特征有限元方法对强对流溶质运移模型进行了求解,并将其结果与标准Galerkin有限元和解析解进行对比.结果表明:标准Galerkin有限元方法会产生强烈的数值振荡;Wavelet-Galerkin有限元方法的时空定位效果好;迎风有限元方法能够有效降低数值振荡现象,但迎风因子对解的影响较大,而且会带来时间延迟;特征有限元方法能够提高解的精度.故可以认为特征有限元方法是求解强对流地下水溶质运移模型的首选方法.

Drawdown due to Temporally Varying Pumping Discharge: Inversely Estimating Aquifer Parameters

A ramp kernel method is proposed for accurately calculating the drawdown due to any temporal variation in pumping discharge. The use of the ramp kernels assumes the linear variation between the two consecutive measured pumping discharges. The prior studies assume a rectangular variation between the two consecutive measured pumping discharges. In the rectangular variation, a uniform pumping rate is assumed during a time span. An analytical equation for calculating the ramp kernel is derived. An optimization method is used with the proposed ramp kernels for inversely estimating the aquifer parameters from drawdown due to an arbitrary unsteady pumping discharge. Unlike the prior methods, the proposed method accurately identifies the parameters even when the sampling interval for the drawdown and pumping discharge is longer than that needed for assuming a linear variation. The proposed method outperforms the prior method. Application of the proposed method is illustrated using examples.     

Love in psychotherapy.

Relational and intersubjective concepts are used to present new ideas about love in psychotherapy. Love is a fundamental creative and propulsive force in therapy. Therapy is a mutually loving process addressing the problematic of love. The therapist's subordinated subjectivity has importance in this experience. Developed but inhibited love occurs in many patients as a result of loving but flawed parenting. As actualization of love progresses during therapy, so does actualization of self. The actualization of love proceeds through 3 successive stages: desire, belief, and hope. The struggle for recognition is fundamental to these developments. The role of love in therapy is theorized on the basis of philosophical, sociological, and psychoanalytic ideas. A case report demonstrates the above approach.

Housing Law Is Dead. Long Live European Housing Law?

The U.K. discipline of housing law is closely linked to the advice needs of individuals and local councils who have many housing responsibilities. This interdisciplinary study supports people in need of housing, particularly assisting access to social housing, often owned by councils. In France similar groups are supported by a strongly expressed right to housing, which is a principle of constitutional value. However, the French local government is too small and fragmented to support U.K.-type responsibility and stronger rights of other local people can block access to social housing. European influences mean that the U.K. has imported a series of ideas that could mean less access to social housing for people in need and the U.K. discipline of housing law is more complex, diffused, and difficult to promote as a study unit. French legal study suggests European trends: primarily public law, not empirical and oriented to construction, although this is improving. Several ideas for new European legal subject groupings are suggested, particularly rights. The right to housing might be currently ineffective in France but it is unavoidable because of pervasive European use. The discipline of the U.K. housing law is threatened, but such lawyers could create new disciplines adapting its traditional strengths to new European groupings.     

The value of a comparative perspective: Theoretical comment on Pearce et al. (2005).

J. M. Pearce, D. N. George, M. Haselgrove, J. T. Erichson, and M. Good (2005) (see record 2005-13804-017) report that damage to the hippocampus does not impair either delay conditioning, a biconditional discrimination, or a series of complex visual and spatial discriminations that require feature binding, but does impair trace conditioning and the ability to perform a working and reference memory maze task. The J. M. Pearce et al. study highlights the value of a comparative perspective and the value of appreciating the multiple ways in which animals can solve tasks, which together will provide a deeper understanding of the function of the hippocampus.

Damage Modeling of Saturated Rocks in Drained and Undrained Conditions

A new anisotropic damage model is proposed to describe the mechanical and poromechanical behavior of brittle rocks in drained and undrained conditions. Although phenomenological, the model is based on physical grounds of micromechanical analysis. Induced damage is represented by a second rank tensor, which is related to the density and orientation of microcracks. Damage evolution is related to propagation of the microcracks. The effective elastic compliance of the damaged material is obtained from a specific form of the Gibbs free enthalpy function. Irreversible damage-related strain due to residual opening of microcracks after unloading is also captured. The originality of our approach is that a poromechanical model of a saturated medium is constructed by extension of the mechanical model for dry material using micromechanical relationships. All the model parameters are determined from triaxial compression tests performed on dry material. The proposed model is applied to coupled poromechanical tests performed on typical brittle rock in saturated conditions. Comparison between test data and numerical simulations shows overall good agreement. The model proposed is able to describe the main features of poromechanical behavior related to microcracks induced in brittle geomaterials.     

Diversity and leadership.

Comments on the six articles contained in the special issue of the American Psychologist (January 2007) devoted to leadership, written by W. Bennis (see record 2006-23492-002); S. J. Zaccaro (see record 2006-23492-003); V. H. Vroom and A. G. Yago (see record 2006-23492-004); B. J. Avolio (see record 2006-23492-005); R. J. Sternberg (see record 2006-23492-006); and R. J. Hackman and R. Wageman (see record 2006-23492-007). The current authors express concern that the special issue failed to include attention to issues of diversity and intersecting identities as they pertain to leadership. A Special Issue Part II on Diversity and Leadership is being proposed to (a) advance new models of leadership, (b) expand on existing leadership theories, and (c) incorporate diversity and multiple identities in the formulation of more inclusive leadership research and theory. The goal of this special issue will be to revise our theories of leadership and our understanding of effective leadership to include gender, racial/ethnic minority status, sexual orientation, and disability status.

Leadership and attachment theory.

Comments on the six articles contained in the special issue of the American Psychologist (January 2007) devoted to leadership, written by W. Bennis (see record 2006-23492-002); S. J. Zaccaro (see record 2006-23492-003); V. H. Vroom and A. G. Yago (see record 2006-23492-004); B. J. Avolio (see record 2006-23492-005); R. J. Sternberg (see record 2006-23492-006); and R. J. Hackman and R. Wageman (see record 2006-23492-007). The current authors opine that the inclusion of attachment theory in the study of leadership could strengthen leadership theories as a whole.

Case Study of Fluvial Modeling of River Responses to Dam Removal

A plan was made to remove Matilija Dam on the Ventura River. With dam removal, the delta in the reservoir and the downstream channel were expected to undergo major changes in morphology. The FLUVIAL-12 model was employed to simulate reservoir and river channel responses after dam removal. As a first step, the model was calibrated using the Ventura River data to establish its validity. In calibration, the model was used to simulate the fluvial processes starting from the time of dam completion. The simulated sediment deposition above the Matilija Dam matches closely with the deposits measured by the U.S. Bureau of Reclamation. A large amount of sediment was stored in the reservoir; some of the stored sediment would be transported downstream after dam removal. An important consequence of dam removal is the major increase of sediment release to the river channel downstream. The sediment supply to the downstream reach is not only from the stored sediment in the reservoir but also from natural sediment inflow from the upstream watershed. Therefore, sediment supply to the downstream reach will exceed the natural sediment flow before the dam presence. This situation tends to overload the downstream reach with sediment, resulting in excessive deposition. The amount of sediment release from the area above the removed dam is closely related to the changes in reservoir morphology. It is necessary to model changes in the channel bed profile and channel width during erosion in order to determine the amount of sediment removal. The amount of sediment release may not be simulated using an erodible-bed model but it may be determined using an erodible boundary model.     

Cropland Measurement Using Thematic Mapper Data and Radiometric Model

To halt erosion and desertification, it is necessary to quantify resources that are affected. Necessary information includes inventory of croplands and desert areas as they change over time. Several studies indicate the value of remote sensor data as input to inventories. In this study, the radiometric modeling of spectral characteristics of soil and vegetation provides the theoretical basis for the remote sensing approach. Use of Landsat Thematic Mapper images allows measurement of croplands in Saudi Arabia, demonstrating the capability of the approach. The inventory techniques and remote sensing approach presented are potentially useful in developing countries.
