What Do Groups Learn from Their Worldliest Members? Direct and Indirect Influence in Dynamic Teams

This study investigated the consequences of temporary membership changes for itinerant members (who leave their group of origin temporarily to visit a foreign work group) and indigenous members of those origin and foreign groups. We tested the hypothesis that itinerant members' unique knowledge and experience can be transferred from the group where it originated to another group engaged in the same activities. Results showed that all members produced more unique ideas after itinerant members returned to their group of origin than before they left or while they were away; however, the ideas of itinerant members were significantly less likely to be utilized by the group in an essay on group work. After their return, itinerant members were perceived as highly involved in group activity, but also more argumentative, and although they produced more unique ideas than indigenous members, their essay contributions were perceived as less valuable. As a result, itinerant group members had less direct influence after changing groups than they did prior to the membership change.     

Diagnosing Oppositional Defiant Disorder Using the Anxiety Disorders Interview Schedule for DSM-IV: Parent Version and the Diagnostic Interview Schedule for Children

The purpose of this study was to determine whether the Anxiety Disorders Interview Schedule for DSM–IV: Parent Version (ADIS–P) is a valid diagnostic tool for the assessment of Oppositional Defiant Disorder (ODD) in youth. Although there is considerable evidence that the ADIS–P is effective in diagnosing anxiety disorders in youth, no studies have yet examined its validity in assessing ODD. In contrast, a number of studies support the Diagnostic Interview Schedule for Children–Version IV (DISC–IV) as a reliable and valid tool in the assessment of ODD. In the present study, the ADIS–P and DISC–IV ODD modules were administered in a counterbalanced order to the parents of a clinical sample of 106 children between 7 and 14?years of age referred for the treatment of ODD. It was hypothesized that the ODD module of the ADIS–P would be valid as determined by its concurrent and convergent validity with the DISC–IV, the Behavior Assessment System for Children (BASC) Aggression and Conduct Problems scales, and the Disruptive Behavior Disorders rating scale (DBD). Results demonstrated that ADIS–P ODD diagnoses had moderate agreement with DISC–IV ODD diagnoses (κ?=?.46, p?<?.001) and that Pearson correlations of ADIS symptom counts with questionnaire scales were similar in magnitude with correlations of DISC–IV symptom counts with the same questionnaires. Overall, findings suggest that clinicians and researchers can use the ADIS–P as an empirically-supported diagnostic interview for assessing children’s oppositional problems.     

Jesus the Teacher

One of the strongest portraits of Jesus in the Gospels is that of a teacher (Lee, 1988).¹ Other than the title “Lord,” people call Jesus “Teacher” more often than any other epithet in the New Testament, and often with a great deal of respect and admiration (Mark 10:17; Matt 22:16).² Jesus also calls himself a “teacher.” In the story of the preparation for the Last Supper, for example, Jesus instructs his disciples to find a room for the paschal meal and to tell the owner that “the teacher” has need of it (Mark 14:14; Matt 26:18; Luke 22:11). Apart from the portrayal of him as an infant, the earliest picture we have of him is the episode of the 12-year-old Jesus amazing the teachers in the temple with his learning (Luke 2:46-47). Other depictions include the itinerant Jesus teaching multitudes (Matt 5–7), individuals (John 3 and 4), adversaries (Luke 15), and disciples (Mark 4:10-20, 33–34; 7:17-23; 10:10-11,23-31). He teaches in the temple (Matt 26:55; Mark 1117; John 7:14), in synagogues (Matt 4:23; Mark 6:2; Luke 4:15; John 6:59), in houses (Mark 7:17-18; 9:28), from a boat (Luke 5:3), on the hillside (Matt 5:1-2), at a well (John 4:7-30), at table (Luke 7:36-50),on the road (Luke 24:13-32), and by the shore (Mark 2:13; 4:1). In other words, Jesus teaches people wherever he is and wherever they are. In fact, Matt 26:55 evidences that Jesus taught on a daily basis. Today, in the Western world this traveling teacher is considered the most famous pedagogue (Highet, 1950, 190). With these thoughts in mind, let's (1) examine the words used to specify “teacher” in the ancient world and show how Jesus both corresponds to and differs from the perceptions this title implies, (2) suggest some teaching methods used by Jesus, and (3) propose a way modern teachers can learn from him.     

Measuring emotional expression with the Linguistic Inquiry and Word Count

The Linguistic Inquiry and Word Count (LIWC) text analysis program often is used as a measure of emotion expression, yet the construct validity of its use for this purpose has not been examined. Three experimental studies assessed whether the LIWC counts of emotion processes words are sensitive to verbal expression of sadness and amusement. Experiment 1 determined that sad and amusing written autobiographical memories differed in LIWC emotion counts in expected ways. Experiment 2 revealed that reactions to emotionally provocative film clips designed to manipulate the momentary experience of sadness and amusement differed in LIWC counts. Experiment 3 replicated the findings of Experiment 2 and found generally weak relations between LIWC emotion counts and individual differences in emotional reactivity, dispositional expressivity, and personality. The LIWC therefore appears to be a valid method for measuring verbal expression of emotion.     

Itinerant surfaces with spin-orbit couplings,correlations and external magnetic fields: exact results

We analyze, in exact terms, multiband 2D itinerant correlated fermionic systems with many-body spin-orbit interactions, and in-plane external magnetic fields. Even if such systems with broad applicability in leading technologies are non-integrable, we set up an exact solution procedure for them, which is described in details. Casting the Hamiltonian in positive semidefinite form, the technique leads to the ground state, and also characterises the low lying excitation spectrum.     

Surface tension measurement of undercooled liquid Ni-based multicomponent alloys

The surface tensions of liquid ternary Ni–5%Cu–5%Fe, quaternary Ni–5%Cu–5%Fe–5%Sn and quinary Ni–5%Cu–5%Fe–5%Sn–5%Ge alloys were determined as a function of temperature by the electromagnetic levitation oscillating drop method. The maximum undercoolings obtained in the experiments are 272 (0.15T _L), 349 (0.21T _L) and 363?K (0.22T _L), respectively. For all the three alloys, the surface tension decreases linearly with the rise of temperature. The surface tension values are 1.799, 1.546 and 1.357?N/m at their liquidus temperatures of 1719, 1644 and 1641?K. Their temperature coefficients are ?4.972?×?10^–4, ?5.057?×?10^?4 and ?5.385?×?10^?4?N/m/K. It is revealed that Sn and Ge are much more efficient than Cu and Fe in reducing the surface tension of Ni-based alloys. The addition of Sn can significantly enlarge the maximum undercooling at the same experimental condition. The viscosity of the three undercooled liquid alloys was also derived from the surface tension data.     

Frequency of word usage and perceived word difficulty: Ratings of Kučera and Francis words

Twenty-four judges estimated the conceptual difficulty level of 870 five-letter words, using a 5-point scale. The words were selected from three word-frequency categories (1, 5–10, and 50–3,562/million) based on the word counts provided by Ku?era and Francis (1967). The ratings were reliable. Tables in this paper list the means and standard deviations of the ratings for each word. Reaction time (RT) for valid word identification was tested in 20 subjects, using four sets of 50 words designed to test the effects of word frequency and word difficulty. RT was longer for more difficult words when word frequency was held constant. A word-frequency effect on RT was present when difficulty was held constant. The relationship of the results to subjective estimates of word familiarity is discussed.     

A criterion for determining the optimum value of twist in the topological model

In previous works, in which the topological model has been applied to martensitic phase transformations, the value of twist angle ω was determined based on the habit plane-(HP) matching method, where the physical realization of the so-predicted interfacial defect networks may require reorientations of defect line directions by short-range diffusion, though no long-range diffusion was needed. In the present work, a novel criterion for determining the optimum value of twist is proposed so that the predicted interface defects are not only able to fulfil the function of fully accommodating the coherency strains arising on the terrace plane, but also capable of reaching the required position at the HP without long- or short-range diffusions. A numerical analysis for an Fe–20Ni–5Mn alloy is demonstrated based on the newly proposed criterion, and the predictions so obtained are in good agreement with the results provided by the phenomenological theory and experimental measurements.     

The use of the large-scale integrated sensor (LSI) to estimate energy expenditure

The relationship between activity counts from the large-scale integrated sensor (LSI), placed at the hip and ankle, and heart rate-estimated energy expenditure was examined in three nonobese males during three conditions: normal morning activities, a 1-mi walk, and a 2-mi walk. Results showed that estimated caloric expenditure was related to activity counts for both monitoring placements, with correlations between counts and energy expenditure exceedingr=.90. These results show that energy expenditure in the activities sampled can be reliably estimated using activity monitors.This research was supported in part by a grant provided by The John D. and Catherine T.

The roles of dispositional optimism and pessimism in hiv disease progression

Relationships between dispositional optimism and pessimism and the course of HIV infection, determined by changes in viral load and CD4 counts, were studied in a longitudinal cohort of 412 patients on antiretroviral therapy (ART). Multiple regression analyses controlling for baseline levels of disease status, ethnicity, and depressive symptoms demonstrated that higher pessimism at baseline was associated with higher viral load at follow-up (average of 18 months later). Optimism at baseline had a curvilinear relationship with CD4 counts at follow-up. Moderate levels of optimism at baseline predicted the highest CD4 counts at follow-up. Although optimism and pessimism were associated with specific health behaviors (e.g., ART adherence, cigarette use, drug use, dietary practices), none of these behaviors mediated the optimism/pessimism effects. The biologic and behavioral mediators of associations of personality variables with the course of treated HIV infection deserve continued investigation.     

Comparison of the RT3 Research Tracker and Tritrac R3D accelerometers

This study compared the RT3 Research Tracker accelerometer to the Tritrac R3D accelerometer in both laboratory and field settings and tested the hypothesis that the RT3 records higher physical activity counts and smaller standard deviations than the R3D. The RT3 is relatively new and untested and its concurrent validity with existing instruments and physical activity needs to be assessed before being used in research. In this study the RT3 had higher average recordings of physical activity counts in all of the nine testing situations than the R3D. However, in terms of agreement between the instruments, the RT3 might be 582 below or 1,236 above (activity counts) the R3D in assessing physical activity. These results do not establish that the RT3 is more consistently measuring higher physical activity counts than the R3D. Comparing vector magnitude with oxygen consumption and heart rate across the 0% grade testing conditions indicated that the RT3 and R3D are sensitive to changes in various intensities of level ambulation. When the 5%, 10%, and 15% grade on the treadmill protocols were analyzed, low correlations between oxygen consumption and heart rate with vector magnitude responses were found for both the RT3 and R3D. Differences in agreement between the RT3 and R3D did not vary in any systematic way over the range in testing conditions which substantiates that the RT3 and R3D accelerometers are sensitive on flat surfaces but are insensitive to changes in grade.     

Joint custody and the preschool child

A longitudinal study of 25 families, with children aged 14 months-5 years, in joint custody, is reported. Varying motivations that lead divorcing parents to undertake and sustain joint custody are discussed, together with the stresses and gratifications of these arrangements for the parents and children. Findings are that where both parents are motivated primarily by interest in the child, where the parenting is sensitive and where the child is shielded from interparental conflict, young children do well. Such families were not the majority in this study. Significant differences emerged in the adjustment of the 1–3 age group as compared with the 3–5 age group which point to greater difficulties for the 3–5-year-olds.     

Towards a critical psychology of human–animal relations

This article argues that critical psychological engagement with the field of human–animal relations is largely absent, but of potential significance, and begins to outline more concretely what such a perspective might contribute, especially as a form of social psychology. The article provides a brief overview of the emerging psychology of human–animal relations and the extent to which it emphasises situated human–animal interactions in real‐world settings, including from the standpoint of animal participants. Recent elaborations of the “animal turn” outside of the discipline of psychology are considered, as they place fresh emphasis on human–animal interaction and interdependence and might further extend the boundaries of what counts as relations that matter in critical and social psychology. These foundations are argued to offer an invitation to critical psychology to engage more fully in the study of human–animal relations and enliven it as a result.     

Dialogue Between Science and Spirituality: Informational Therapies

Every action, specifically the therapeutic act, is determined by our mental state: love and compassion. Positive thinking, which must lead us in our research and our acts, is based on the fact that therapeutic results are determined by a treatment of the entire human being: “Body–Mind–Spirit,” which is outstretched, according to tradition, on the four levels of consciousness: Plan 7: Body; Plan 6: Metabolism; Plan 5: Mental; Plan 4: Information (Spirituality). Within the context of a chronic condition, homeopathy practice and the use of differentiations factors have been an example of the possible patient's transformation (a journey toward the health state) and of the dialogue between science and spirituality.     

Escalating schedules of incentives increase physical activity with no differences between deposit and no-deposit groups: A systematic replication

Physical inactivity has increasingly affected public health in the United States during the COVID-19 pandemic as it is associated with chronic diseases such as arthritis, cancer, and heart disease. Contingency management has been shown to increase physical activity. Therefore, the present study sought to evaluate the effects of an escalating schedule of monetary reinforcement with a reset contingency on physical activity, as compared between 2 counterbalanced groups in which a monetary deposit of $25 was either required (deposit group) or not (no-deposit group). Twenty-five adults wore Fitbit accelerometers to monitor step counts. An ABA reversal design was used; in the 2 baseline phases, no programmed contingencies were in place for step counts. During intervention, step goals were set using a modified 70^th percentile schedule with a 7-day window: Reaching the first goal would result in $0.25, and incentives increased by $0.25 for each subsequent day in which the goal was met. Failure to reach a goal resulted in a reset of the monetary incentive value to $0.25. Ten out of 12 participants from the deposit group were determined to be responders to intervention, whereas 8 out of 13 participants from the no-deposit group were determined to be responders to intervention. Overall, there were no significant differences between the groups' step counts. However, the deposit group's intervention was cheaper to implement, which suggests that deposit contracts are a viable modification for physical activity interventions.     

Validation of the Five-Factor Model Personality Disorder Prototype Counts with the Personality Assessment Inventory

Five-factor model (FFM) personality disorder (PD) prototype scores drawn from the revised NEO-Personality Inventory (NEO-PI-R) have demonstrated strong convergent validity with clinical measures of PD (Miller in Journal of Personality, 80, 1565–1591, 2012). However, an examination of the relations between the Personality Assessment Inventory (PAI; Morey 1991), which is widely used in personality assessment research, and the FFM PD prototype “count” method, has not been conducted. The present study examines the convergent validity of the FFM borderline, antisocial, and psychopathy prototype counts with the Borderline Features (BOR) and Antisocial Features (ANT) full scales and subscales from the PAI. Furthermore, the BOR and ANT scales are correlated with all 30 NEO-PI-3 facets to empirically evaluate the rationally-selected facet scales used in the borderline, antisocial, and psychopathy PD counts. Five hundred thirty-five undergraduate students completed both the NEO-PI-3 and the PAI. The PD counts demonstrated strong convergent and discriminant validity with the PAI clinical scales. Facet-level analyses generally supported the structure of the PD count formulas, and the exceptions align with previous evidence that the Competence, Dutifulness, and Self-Discipline facets (from the Conscientiousness domain of the FFM) associate strongly with the BOR scale.     

An evaluation of evaluative personality terms: a comparison of the big seven and five-factor model in predicting psychopathology

Two personality models are compared regarding their relationship with personality disorder (PD) symptom counts and with lifetime Axis I diagnoses. These models share 5 similar domains, and the Big 7 model also includes 2 domains assessing self-evaluation: positive and negative valence. The Big 7 model accounted for more variance in PDs than the 5-factor model, primarily because of the association of negative valence with most PDs. Although low-positive valence was associated with most Axis I diagnoses, the 5-factor model generally accounted for more variance in Axis I diagnoses than the Big 7 model. Some predicted associations between self-evaluation and psychopathology were not found, and unanticipated associations emerged. These findings are discussed regarding the utility of evaluative terms in clinical assessment.
