A modest/immodest proposal: Reciprocal foster families

In this article we describe the concept of reciprocal foster families a strength-based approach to helping families in poverty. This approach focuses on the resources that all families have to offer each other. The goal of reciprocal foster families approach is to restrict the role of professionals and develop trust in the intuitive wisdom of natural networks of people and families as they help each other succeed in times of difficulty.     

The cyclopean eye vs. the sighting-dominant eye as the center of visual direction

In three experiments, competing hypotheses concerning the center of visual direction were examined with the stimuli used in the Card test which requires a subject to position the card with a hole so that a target can be seen. Each experiment used six right- and six left-sighting-eye subjects. In Experiment 1, the aperture and the target were collinear with the sighting eye. The mean apparent locations of the aperture when the target was fixated, and of the target when the aperture was fixated, were consistent with only the cyclopean-eye hypothesis; that is, the 95% confidence intervals of these means contained the predicted values from the cyclopean-eye hypothesis but not those from the sighting-eye hypothesis. In Experiment 2, subjects moved the card from the side of the nonsighting eye, and in 88% of the trials it was stopped when the nonsighting eye viewed the target. In Experiment 3, the target was viewed through the aperture with both the sighting and nonsighting eye in six different stimulus arrangements. The 95% confidence intervals of all 12 mean apparent locations of the targets contained the predicted values from the cyclopean-eye hypothesis but none of those from the sighting-eye hypothesis. These results are compatible with the cyclopean-eye hypothesis, and we therefore conclude that the sighting eye is not the center of visual direction.     

Effects of medical resonance therapy music on patients with psoriasis and neurodermatitis—A pilot study

Stress medicine has shown that emotional disharmony can be a substantial factor for skin diseases. The harmonisation of the emotional status and a corresponding reduction of stress hormones by the Medical Resonance Therapy Music^® (MRT-Music) as shown in other studies (1,2,3,4) inspired us to investigate its benefits for patients with psoriasis vulgaris and neurodermatitis (neurodermatitis constitutionalis atopica). Over a period of 14 days we measured the parameters of blood pressure, heart rate, stimulus to scratch and the degree of sickness in two, respectively four groups of 68 patients in total: two experimental groups (psoriasis/neurodermatitis) and two control gropus. All patients received the normal treatment of our hospital, the experimental groups were additionally treated with 3 × 30 minutes of MTR-Music per day, while the controls were asked to somehow relax during this time. In the experimental groups the measurements showed to somehow relax during this time. In the experimental groups the measurements showed a reduction of blood pressure and heart rate and revealed an enhanced reduction of the stimulus to scratch and an enhanced reduction in the degree of sickness. Interestingly the effects of MRT-Music were stronger with the psoriasis patients than with the neurodermatitis patients. The results of this pilot study convinced us to offer the treatment with the Medical Resonance Therapy Music to all our patients.     

Cannabinoid Agonists and Antagonists Modulate Lithium-induced Conditioned Gaping in Rats

Considerable evidence indicates that conditioned gaping in rats reflects nausea in this species that does not vomit. A series of experiments evaluated the potential of psychoactive cannabinoid agonists, delta-9-THC and HU-210, and non-psychoactive cannabinoids, Cannabidiol (CBD) and its dimethylheptyl homolog (CBD-dmh), to interfere with the establishment and the expression of conditioned gaping in rats. All agents attenuated both the establishment and the expression of conditioned gaping. Furthermore, the CB1 antagonist, SR-141716, reversed the suppressive effect of HU-210 on conditioned gaping. Finally, SR-141716 potentiated lithium-induced conditioned gaping, suggesting that the endogenous cannabinoid system plays a role in the control of nausea.     

Workaholism as Discretionary Time Investment at Work: An Experience-Sampling Study

Adopting an operational definition of workaholism as discretionary investment of considerable time at work, the purpose of the present study was to test hypotheses regarding the cognitive aspect of workaholism, as well as the positive and negative/addictive views of this construct. The study employed an experience‐sampling method (ESM), using a sample of 65 full‐time employees who completed the ESM forms at four random times during the day for one week. Results indicated that workaholism was associated with continued cognitive engagement with work, accompanied by a preference for work over leisure activity and higher positive affect during work activity than during leisure activity. No significant differences were found between workaholics and non‐workaholics with regard to the likelihood of performing work‐related activities during leisure activity, or in the levels of physical discomfort and negative affect during the weekend. These results highlight the utility of an operational framework for studying the variety of workaholism correlates. Theoretical and applied implications are discussed. A partir d’une définition opérationnelle de l’addiction au travail comme étant un investissement sans contrôle d’un temps considérable consacré au travail, cette recherche s’est donné comme objectif de mettre à l’épreuve des hypothèses relatives à la dimension cognitive de l’addiction au travail, ainsi que les aspects positifs et négatifs (addictifs) de ce concept. Cette recherche a exploité la méthode de l’échantillonnage des expériences (ESM) à partir d’un échantillon composé de 65 salariés à plein‐temps qui ont rempli la feuille de recueil des données quatre fois par jour au hasard pendant une semaine. Les résultats ont montré que l’addiction au travail était liée à un engagement cognitif permanent vis‐à‐vis du travail, associéà une plus forte attirance pour le travail que pour les loisirs et à un état affectif plus fortement positif lors du travail qu’à l’occasion des activités de loisirs. On n’a pas trouvé de différences significatives entre les drogués du travail et les autres en ce qui concerne la probabilité de réaliser des activités relevant du travail pendant les loisirs, ou dans le niveau d’inconfort physique et le poids des affects négatifs pendant le week‐end. Ces résultats montrent l’utilité d’un schéma opérationnel dans l’étude de la diversité des phénomènes reliés à l’addiction au travail. Les implications théoriques et pratiques sont examinées.     

Infants’ grip strength predicts mu rhythm attenuation during observation of lifting actions with weighted blocks

Research has established that the body is fundamentally involved in perception: bodily experience influences activation of the shared neural system underlying action perception and production during action observation, and bodily characteristics influence perception of the spatial environment. However, whether bodily characteristics influence action perception and its underlying neural system is unknown, particularly in early ontogeny. We measured grip strength in 12‐month‐old infants and investigated relations with mu rhythm attenuation, an electroencephalographic correlate of the neural system underlying action perception, during observation of lifting actions performed with differently weighted blocks. We found that infants with higher grip strength exhibited significant mu attenuation during observation of lifting actions, whereas infants with lower grip strength did not. Moreover, a progressively strong relation between grip strength and mu attenuation during observation of lifts was found with increased block weight. We propose that this relation is attributable to differences in infants’ ability to recognize the effort associated with lifting objects of different weights, as a consequence of their developing strength. Together, our results extend the body's role in perception by demonstrating that bodily characteristics influence action perception by shaping the activation of its underlying neural system.     

Sample size determination for at test given at value from a previous study: A FORTRAN 77 program

When uncertain about the magnitude of an effect, researchers commonly substitute in the standard sample-size-determination formula an estimate of effect size derived from a previous experiment. A problem with this approach is that the traditional sample-size-determination formula was not designed to deal with the uncertainty inherent in an effect-size estimate. Consequently, estimate-substitution in the traditional sample-size-determination formula can lead to a substantial loss of power. A method of sample-size determination designed to handle uncertainty in effect-size estimates is described. The procedure uses thet value and sample size from a previous study, which might be a pilot study or a related study in the same area, to establish a distribution of probable effect sizes. The sample size to be employed in the new study is that which supplies an expected power of the desired amount over the distribution of probable effect sizes. A FORTRAN 77 program is presented that permits swift calculation of sample size for a variety oft tests, including independentt tests, relatedt tests,t tests of correlation coefficients, andt tests of multiple regressionb coefficients.
