Structure, Self-Regulating Sequences, and Institutional Third Parties in Therapy: The Veterans Administration as a Model

This article examines the structural organization and sequences of interaction among therapists, institutions, and patients and their families that contribute to the problem of institutional dependence. Our contention is that when patients have become dependent on an institution for the livelihood and/or for the stability it represents, they are only one part of a systemic relationship characterized structurally by enmeshed boundaries, and sequentially by self-regulating feedback loops. We use this premise to outline the nature of the enmeshed transactions in patient-therapist, patient-institution, and therapist-institution relationships. Family interfaces with this triad are also addressed. Sequentially, we outline the interactions among patient, family, therapist, and institution that lead to hierarchical incongruities. These sequences tend to produce self-regulating feedback loops that perpetuate and maintain the structure of the system and its patterns of interaction. The final part of this article demonstrates how we strategically use a therapy team to manipulate the hierarchical incongruities and, hence, the recursive complementarity, that characterize the interactions between and among the members of this suprasystem. Besides manipulating the role of the therapist through team intervention, we also present several paradoxical and structural interventions that have been helpful when institutions have become third parties to therapy.     

Dual-coding, context-availability, and concreteness effects in sentence comprehension: an electrophysiological investigation.

Event-related potentials were recorded in 2 experiments while participants read sentences in a word-by-word congruency judgment task. Sentence final words were either congruent, semantically anomalous (Experiments 1 and 2), or neutral (Experiment 2) with respect to sentence context. Half of all final words referred to concrete and half to abstract concepts. A different scalp distribution of the N400 to concrete and abstract final words was found for anomalous and neutral, but not congruent sentences. Although the interaction of context and concreteness is consistent with the context-availability model, the differential scalp distribution of effects for concrete and abstract words, as well as larger context effects for concrete words, was interpreted as being more consistent with an extended dual-code account of semantic processing.     

Relative contributions of envelope maxima and minima to comodulation masking release

Comodulation masking release (CMR) is a phenomenon that demonstrates the sensitivity of the auditory system to across-frequency differences in the temporal modulation pattern of a complex waveform. In this paper, we review briefly some of the data on the physical parameters that affect CMR and describe models that have been proposed to account for CMR -- namely, models based upon envelope equalization/cancellation, across-frequency envelope correlation, and “dip listening”. The present literature is ambiguous with regard to the relative importance of energy in the peak and dip regions of the waveform envelope. We therefore performed a series of experiments to investigate this issue. In the first experiment, we examined CMR for signals that resulted either in a uniform increment or in uniform decrement in the masking noise centred on the signal frequency. This was accomplished by using a 20-Hz-wide noise band centred on 700 Hz as both the masker and as the signal, adjusting the phase angle between the signal and masker to either 0° (increment) or 180° (decrement). Conditions were examined where either zero, one, two, four, or six comodulated flanking bands were present. Results indicated positive CMRs for all conditions in which a comodulated flanking band was present. CMR increased as the number of flanking bands increased for intensity increments, but not for intensity decrements. The remaining experiments examined conditions where signals were present only in masker peaks, or only in masker dips. The results of these experiments indicated relatively large CMRs when the signal occurred in dip regions, but no CMR when the signal occurred in peak regions. Whereas some of the results of the above experiments would be difficult to account for in terms of the dip listening hypothesis of CMR, the present findings did indicate that the stimulus cues that give rise to CMR appear to be derived primarily from the dip regions of the masking noise.     

Does salary discussion hurt the developmental performance appraisal?

The “split roles of performance appraisal” perspective introduced by H. H. Meyer and associates in 1965 (H. H. Meyer, E. Kay, J. R. P. French, Jr. Harvard Business Review, 43, 123–129) argues that discussing salary has a negative impact on the developmental aspects of performance appraisal (PA). This research provides the first empirical evaluation of that proposition. Of key interest is the relationship between salary discussion and process characteristics (e.g., participation), content characteristics (e.g., work planning), and the outcomes (e.g., utility) of PA. Also, several contingency factors are investigated to see if they moderate the impact of discussing salary. The results indicate that salary discussion has either no impact or a positive impact on PA process, content, and outcomes. Of the five contingency factors, only performance level has a consistent moderating impact. Low performers, compared to high performers, evidence a stronger positive relationship between salary discussion and key PA variables.     

Invigorating ��Nanoethics��: Recommendations for Improving Deliberations in Taiwan and Beyond

Nanotechnology is the new(est) star in the high technologies sky. While nanotechnologies remain technologies of promise and potential, a growing number of nano-materials and nano-particle-reliant products are being produced. And although a growing number of academic, policy and industry reports are exploring nanotechnologies, there are very few genuine ethical assessments of nanotechnologies as they exist and might evolve in the coming years. Many questions have yet to be answered about the nature, development, and social and commercial deployment of nanotechnologies and what that means for the human condition and the preservation of our core values. We argue that the early and potentially risky nature of this interdisciplinary science does not justify a blinkered focus on risk assessment and management to the detriment of deep and ranging ethical evaluations. Much improved ethics evaluations must be undertaken, particularly in Taiwan where very little has happened despite grand expectations for, and funding of, the science. In this paper, we uncover the development imperatives for nanotechnologies, demonstrate the paucity of genuine nanoethics exercises, outline key questions for stakeholders undertaking nanoethics exercises to consider, and we articulate some preliminary actions for Taiwan (and other similarly situated jurisdictions).     

Socioeconomic and psychological correlates of postpartum depression at 6 months in Dhaka,Bangladesh

To current study aimed to estimate the point prevalence and identify correlates of postpartum depression (PPD) in a sample of mothers in Dhaka. A total of 235 participants from low- and middle-SES neighbourhoods in Dhaka completed the Edinburgh Postnatal Depression Scale (EPDS) and other assessments of socioeconomic and psychological factors at 24 weeks postpartum. Regression models were fit to explore potential correlates of PPD. The estimated prevalence of high PPD risk in the current sample is 24.3%. In multivariable linear regression models, recent life events, perceived stress and household resources (e.g., access to cooking gas, telephone, furniture, electricity, television, etc.) were significantly associated with PPD. The association of social support with PPD when controlling for other variables was sensitive to the choice of social support measure, highlighting an important methodological issue. The point prevalence of PPD among poor, urban mothers in Bangladesh ranges from 12.3 to 28.5%, with psychological risk factors and household resources as strong correlates.
