    Notes: Influence and persuasion are related, fundamental constructs in interpersonal communication. Both display the relationship qualities of interdependence, bidirectionality, reciprocity, and multiple levels of analysis. Yet, empirical validation of these relationship qualities is lacking, largely due to an absence of appropriate methods and statistical procedures. This article uses the family social relations model (SRM) to test for the personal relationship qualities of influence and persuasion in the family decision-making context of buying a new car. New relationship measures of influence and persuasion were developed because, historically, measures have been at the individual level. The sample size of 110 families proved sufficient for stable parameter estimates. The results uncovered patterns in the relationship qualities of influence and persuasion across 3 decisions families make when buying a new car (i.e., how much to spend, car model choice, final decision). The findings confirm that both influence and persuasion are truly relational. The novel use of the model across decisions allowed the patterns of relationships among family members to be compared, and demonstrated the importance of the relationship qualities of influence and persuasion in decision making. Predictions were examined across decisions as well so as to check the consistency of hypotheses. The results provide further insight into the meaning of influence and persuasion, and of SRM terms.

    Notes: The current methodological policy in Psychophysiology stipulates that repeated-measures designs be analyzed using either multivariate analysis of variance (ANOVA) or repeated-measures ANOVA with the Greenhouse–Geisser or Huynh–Feldt correction. Both techniques lead to appropriate type I error probabilities under general assumptions about the variance-covariance matrix of the data. This report introduces mixed-effects models as an alternative procedure for the analysis of repeated-measures data in Psychophysiology. Mixed-effects models have many advantages over the traditional methods: They handle missing data more effectively and are more efficient, parsimonious, and flexible. We described mixed-effects modeling and illustrated its applicability with a simple example.

    Notes: The increase in sheet resistance of indium–tin–oxide (ITO) films on polyethylene terephthalate with increasing tensile strain is reported. The increase in resistance is related to the number of cracks in the conducting layer which depends upon applied strain and film thickness. We propose a simple model that describes the finite but increasing resistance in the cracked ITO layer in terms of a small volume of conducting material within each crack. © 2000 American Institute of Physics.

    Notes: The K1 capsule, an α(2,8)-linked polymer of sialic acid, is an important virulence determinant of invasive Escherichia coli. The 17-kb kps gene cluster of E. coli K1 encodes the information necessary for capsule expression at the cell surface. Two proteins, KpsM and KpsT, play a role in the transport of capsular polysaccharide across the cytoplasmic membrane, utilizing the energy from ATP hydrolysis. They belong to the ATP-binding cassette superfamily of transport proteins. In this study, we purified KpsT in its native form and show that the purified protein is able to bind ATP, undergo an ATP-dependent conformational change and hydrolyze ATP. Protease accessibility studies demonstrate the in vivo interaction between KpsM and KpsT.

    Notes: Abstract –  Objectives:  The aim of this study was to explore differences in behaviour (characteristics and opinions) among general dental practitioners (GDPs), using either a fixed (Fx) or an individualized recall interval (Iv) between successive routine oral examinations (ROEs).Methods:  In the year 2000, data were collected by means of a written questionnaire sent to a random stratified sample of 610 dentists of whom 521 responded, of which 508 (83%) were used for analysis.Results:  Two groups of GDPs were distinguished based on their answer to the question: ‘Do you apply for all patients a fixed recall interval between two successive ROEs?’ Fifty-one per cent of the GDPs (n = 257) applied Fxs for all patients, generally for a period of 6 months. Ivs were applied by 49% (n = 251) of GDPs, depending on the determination of specific patient characteristics. Logistic regression analysis showed that GDPs applying Fxs also used fixed periods between successive bitewing radiographs for all patients. Furthermore, dentists applying Ivs required more time to conduct an ROE, partly because of a more extensive periodontal screening. GDPs applying Fxs, adhered more to the opinion that a fixed recall regime (every 6 months, as existed before 1995) should be re-introduced, whereas the GDPs in support of Ivs were more in favour to support the opinion that the ROE is ‘an excellent instrument for effective, individualized oral care’.Conclusions:  Dutch GDPs differ in the way they deal with the determination of recall interval frequency. These are also specific differences in performance and opinions regarding ROE. With the changing prevalence of oral diseases and the skewed distribution within populations, further research is advocated on consistent decision making to determine the most appropriate recall policy in preventing oral disease.

    Notes: Abstract –Objectives: The aim of this study was to compare four methods for assessing the preferences of the dental profession for topics to be considered for the development of clinical practice guidelines.Methods:  The methods were: (1) a survey among dentists, (2) an analysis of topics discussed in dental peer groups, and (3) screening of dental journals. A fourth method was obtained from method number 3. The frequencies of the reported topics were calculated for each of the methods. For the fourth method, the number of publications per topic were plotted against the year of publication, and the slope of the linear regression line was used as an indicator. Within each of the four methods, the topics were ranked according to the frequency in which they were reported, and to the slope value. The reliability of the methods was tested by the “item-rest sum correlation”, which is the correlation of the rank positions of one method with the sum of the rank positions obtained by the remaining three methods.Results:  In using all methods, a total of 1027 topics were obtained. Reclassification resulted in 34 topics. Moderate item-rest sum correlations ranging from 0.34 to 0.48 were found for all methods, indicating that the rank order of every method moderately predicts the sum of the rank orders obtained by all other methods. The topic ‘prevention of cross-infection’ had the highest overall rank position.Conclusion:  It is concluded that the four applied methods appeared to provide a consistent ranking of potential topics. In view of the fact that the questionnaire method is generally applicable, this method should be preferred for assessing dentists' preferences for topics to be considered for the development of clinical practice guidelines.

    Molecular dynamics of a dense fluid of polydisperse hard spheres (2000)

    Notes: Slow dynamics in a fluid are studied in one of the most basic systems possible: polydisperse hard spheres. Monodisperse hard spheres cannot be studied as the slow down in dynamics as the density is increased is preempted by crystallization. As the dynamics slow they become more heterogeneous, the spread in the distances traveled by different particles in the same time increases. However, the dynamics appears to be less heterogeneous than in hard-spherelike colloids at the same volume fraction. The particles which move least far in a characteristic relaxation time and, particularly, the particles which move farthest in the same time are clustered, not randomly distributed throughout the sample. The slow dynamics (but not the statics) show strong finite size effects, suggesting that slow dynamics are correlated over distances of several diameters. We study the dynamics at three different widths of the distribution of diameters of the hard spheres. For each width, the relaxation time is the same function of the compressibility factor, suggesting that this determines the relaxation time for hard spheres. © 2000 American Institute of Physics.

    Notes: Objective To determine whether fetal response to needling resembles the fetal ‘brain sparing’ response seen with hypoxaemia.Design Prospective observational study.Setting Centre for Fetal Care, Queen Charlotte's and Chelsea Hospital, London.Population Eighty-five pregnant women undergoing invasive procedures associated with fetal prenatal diagnosis and/or management.Methods The femoral artery and the middle cerebral artery pulsatility index were measured by Doppler ultrasonography before and after 89 invasive procedures (fetal blood sampling, transfusion, bladder or cyst aspiration, shunt insertion and amniocentesis, between 17 and 36 weeks). Cases in which the fetal body was transgressed were compared with ‘control’ fetuses undergoing invasive procedures which did not directly involve needling the fetus (amniocentesis and placental cord insertion procedures).Main outcome measures Femoral artery and middle cerebral artery pulsatility index.Results The femoral artery pulsatility index rose after transgression [median change (Δ) 0.73; 95% confidence interval (CI) 0.51 to 0.98]. In contrast, there was no significant change in femoral artery pulsatility index after non-transgression procedures (mean Δ 0.28; 95% CI −0.20 to 0.76). Analysis confirmed the fall in middle cerebral artery pulsatility index after transgression procedures (median Δ−0.19; 95% CI −0.07 to −0.35), but there was also a significant fall in middle cerebral artery pulsatility index after non-transgression procedures (mean Δ−0.47; 95% CI −0.23 to −0.71).Conclusions The human fetus mounts a peripheral haemodynamic response to invasive procedures involving transgression of the fetal body, which is consistent with the brain sparing effect. However, the change in middle cerebral artery pulsatility index in both transgression and control procedures suggests that the changes and mechanisms may be more complex than previously thought.

    Notes: Aims  To assess the efficacy of buprenorphine compared with methadone maintenance therapy for opioid dependence in a large sample using a flexible dosing regime and the marketed buprenorphine tablet.Design  Patients were randomized to receive buprenorphine or methadone over a 13-week treatment period in a double-blind, double-dummy trial.Setting  Three methadone clinics in Australia.Participants  Four hundred and five opioid-dependent patients seeking treatment.Intervention  Patients received buprenorphine or methadone as indicated clinically using a flexible dosage regime. During weeks 1–6, patients were dosed daily. From weeks 7–13, buprenorphine patients received double their week 6 dose on alternate days.Measurements  Retention in treatment, and illicit opioid use as determined by urinalysis. Self-reported drug use, psychological functioning, HIV-risk behaviour, general health and subjective ratings were secondary outcomes.Findings  Intention-to-treat analyses revealed no significant difference in completion rates at 13 weeks. Methadone was superior to buprenorphine in time to termination over the 13-week period (Wald χ2 = 4.371, df = 1, P = 0.037), but not separately for the single-day or alternate-day dosing phases. There were no significant between-group differences in morphine-positive urines, or in self-reported heroin or other illicit drug use. The majority (85%) of the buprenorphine patients transferred to alternate-day dosing were maintained in alternate-day dosing.Conclusions  Buprenorphine did not differ from methadone in its ability to suppress heroin use, but retained approximately 10% fewer patients. This poorer retention was due possibly to too-slow induction onto buprenorphine. For the majority of patients, buprenorphine can be administered on alternate days.
