Psychotherapist self-disclosure and transparency in the Internet age.

All psychotherapists engage in self-disclosure with their clients. At times it may be deliberate or nondeliberate, verbal or nonverbal, and avoidable or unavoidable. Yet, modern-day Internet technologies have redefined the meaning and applications of self-disclosure and transparency in psychotherapy. Consumers of mental health services can easily access large amounts of information about their psychologists. Clients' online searches about their psychotherapists may range from normal curiosity to criminal stalking. Following an examination of these issues, three invited experts share their commentaries on the issues raised. A historical review of self-disclosure in the mental health professions and the opposition of many theorists and practitioners to its use are provided. Further, the roles of Internet social networking and online communities for psychotherapists and their clients and prospective clients are explored, along with the clinical meaning of the ever-increasing digital transparencies of psychologists, trainees, and clients. Advice is provided for how to view, understand, and consider web postings by psychotherapists, clients, and others. Implications for clinical practice and training are provided along with recommendations for how to effectively address issues of digital transparency.

Constant-Power Bit Loading for Multicarrier Systems: BER-Allocation

Adaptive bit loading algorithms are proposed for multi-channel systems in general, and orthogonal frequency division multiplexing in particular. A discrete coding-modulation adaptation is considered. Constant power allocation is assumed for all subchannels, while the bit error rate on different subchannels is unconstrained. The proposed algorithms are computationally efficient and require limited amount of feedback resources. Their performance compare favorably with other practical schemes known in the art.     

Simultaneous counter-flow of chlorinated volatile organic compounds across the saturated-unsaturated interface region of an aquifer

Concentrations of chlorinated volatile organic compounds (Cl-VOCs) at the saturated-unsaturated interface region (SUIR; depth of ∼18 m) of a sandy phreatic aquifer were measured in two monitoring wells located 25 m apart. The concentrations of the Cl-VOCs obtained above and below the water table along a 413-day period are interpreted to depict variable, simultaneous and independent movement of trichlorothene, tetrachloroethene, 1,1-dichloroethene, cis-1,2-dichloroethene, 1,1,1-trichloroethane, chloroform and 1,1-dichloroethane vapors in opposite directions across the SUIR.     

Reduced Functional Consistency of Uninterpreted Functions

A reduction of Equality Logic with Uninterpreted Functions (EUF) to Equality Logic with Ackermann's method suffers from a quadratic growth in the number of functional consistency constraints (constraints of the form x=y→F(x)=F(y)). We propose a framework in which syntactic characteristics of function instances (their signature) is used for guessing which constraints will possibly be needed for the proof. This framework can be either combined in an abstraction-refinement loop, or, in some cases, be used without refinement iterations. The framework is suitable for equivalence verification problems, which is one of the typical uses of Uninterpreted Functions. It enabled us to verify dozens of verification conditions resulting from Translation Validation that we could not prove otherwise.     

The moderating effect of risk on the relationship between planning and success

Project planning is considered to be critical for project success. However, recent literature questions whether planning has similar importance in various contexts. This paper investigates the effectiveness of planning through an analysis of 183 project manager–supervisor dyads. Results show that the level of risk moderates the impact of planning on success, and in different ways for various success measures. Practical implications of these results suggest project managers to put more emphasis on planning in high risk project situations in order to meet project efficiency, whereas project steering committees to be more involved in approving plans of low risk projects to support benefit realization.     

A note on the memory length of optimal nonlinear filters

Consider the one-dimensional filtering problem with state diffusion coefficient ^γ and observation noise coefficient ^1−γ, where is fixed. In the regime →0, we provide an example of state dynamics and a corresponding asymptotically optimal filter whose memory length is short in a strong sense. This stands in contrast with the behavior of the correlation memory length, proposed in [7], which stays bounded away from zero as →0.

Project benefit management: Setting effective target benefits

Target benefits such as “reduced operational costs” are project goals that can contribute to the long-term improvement of organizational performance following project completion. Setting effective target benefits is critical because it supports project investment decisions, clear project management direction, and thereby enhanced project and organizational performance. Based on goal setting theory, we present three studies to develop and validate a scale to measure effective target benefits. The proposed scale is comprised of three dimensions - specificity (e.g., specific target values), attainability (e.g., the capacity to realize the target benefits), and comprehensiveness (e.g., reflect the views of key stakeholders). This scale can be used by senior managers to assess proposed projects' target benefits, contributing to more informed project investment decision-making and the subsequent benefit management process. Theoretically, it can also be used as an instrument to facilitate theory development in the fields of project benefit management, strategy implementation, and organizational performance.
