Female Ph.D. Completion: How Field of Study Moderates the Predictive Relationships Between Social and Academic Interactions With Faculty, Research Productivity and Degree Completion

The purpose of this study was to seek further understanding of how field of study moderated the predictive relationships between social interactions with faculty, academic interactions with faculty, research productivity, and female Ph.D. students\u27 degree completion. A survey was conducted to collect data on the participants\u27 degree completion, satisfaction with social and academic interactions with faculty, research productivity as well as their field of study. The sample included 412 female former Ph.D. students in various fields at a large, public research university in the mid-Atlantic region who were enrolled between 1993 and 2004. Logistic regression analyses were conducted to see if (1) field of study moderated the predictive relationships between social and academic interactions with faculty, research productivity and degree completion, and if (2) social and academic interactions with faculty and research productivity had predictive utility on degree completion. The results indicated that (1) field of study had no moderator effect on the predictive relationships between social and academic interactions with faculty, research productivity, and degree completion, and (2) none of the predictor variables predicted degree completion

The Effects of Messages on Environmental Behavior

Over the past few decades environmental awareness and education have increased without a corresponding increase in pro-environmental behavior. Recent research on public service announcements and social marketing theory indicate that positive injunctive with positive descriptive norms are most effective in increasing proenvironmental behavior. The current study focused on the impact of different types of environmental messages on promoting recycling behavior in college students. Over 250 recycling actions were measured in the experiment. It was hypothesized that the positive injunctive with positive descriptive statement would be most effective in causing more university students to recycle. The findings, although not statistically significant, suggest that an educational based statement may be more effective on behavior than an emotional statement. One strength of this study is the ability to measure behavior directly and compare it to students’ behavioral intentions

Exertional evaluation for BT

Bronchial thermoplasty (BT) had been reported to improve the symptoms of severe asthma. However, the exertional responses of BT based on the mechanisms have not been elucidated. A 57-year-old man and a 60-year-old woman underwent BT due to intractable severe asthma. We evaluated the therapeutic effects of BT using cardiopulmonary exercise testing (CPET). After BT, the exercise time during CPET substantially prolonged reducing exertional dyspnea in the former (good), but not in the latter (poor). In the good responder, the high air remaining in the lung after expiration (i.e., inspiratory tidal volume minus expiratory tidal volume) during CPET decreased after BT. In contrast, in the poor responder, the high air remaining after expiration during exercise was not obtained before BT. Further investigations are necessary to confirm that the presence or absence of the exertional wasted ventilation on CPET may be informative to evaluate the therapeutic effects of BT

Psychosocial functioning in patients with treatment-resistant depression after group cognitive behavioral therapy

<p>Abstract</p> <p>Background</p> <p>Although patients with Treatment Resistant Depression (TRD) often have impaired social functioning, few studies have investigated the effectiveness of psychosocial treatment for these patients. We examined whether adding group cognitive behavioral therapy (group-CBT) to medication would improve both the depressive symptoms and the social functioning of patient with mild TRD, and whether any improvements would be maintained over one year.</p> <p>Methods</p> <p>Forty-three patients with TRD were treated with 12 weekly sessions of group-CBT. Patients were assessed with the Global Assessment of Functioning scale (GAF), the 36-item Short-Form Health Survey (SF-36), the Hamilton Rating Scale for Depression (HRSD), the Dysfunctional Attitudes Scale (DAS), and the Automatic Thought Questionnaire-Revised (ATQ-R) at baseline, at the termination of treatment, and at the 12-month follow-up.</p> <p>Results</p> <p>Thirty-eight patients completed treatment; five dropped out. For the patients who completed treatment, post-treatment scores on the GAF and SF-36 were significantly higher than baseline scores. Scores on the HRSD, DAS, and ATQ-R were significantly lower after the treatment. Thus patients improved on all measurements of psychosocial functioning and mood symptoms. Twenty patients participated in the 12-month follow-up. Their improvements for psychosocial functioning, depressive symptoms, and dysfunctional cognitions were sustained at 12 months following the completion of group-CBT.</p> <p>Conclusions</p> <p>These findings suggest a positive effect that the addition of cognitive behavioural group therapy to medication on depressive symptoms and social functioning of mildly depressed patients, showing treatment resistance.</p

Dyspnea and the Varying Pathophysiologic Manifestations of Chronic Obstructive Pulmonary Disease Evaluated by Cardiopulmonary Exercise Testing With Arterial Blood Analysis

Background: Patients with chronic obstructive pulmonary disease (COPD) show varying mechanisms of exertional dyspnea with different exercise capacities.Methods: To investigate the pathophysiologic conditions related to exertional dyspnea, 294 COPD patients were evaluated using cardiopulmonary exercise testing (CPET) with arterial blood analyses, with the patients classified into two groups according to their exercise limitation: the leg fatigue group (n = 58) and the dyspnea group (n = 215). The dyspnea group was further subdivided into four groups based on peak oxygen uptake (V°O2 in mL/min/kg): group A (&lt; 11), group B (11 to &lt; 15), group C (15 to &lt; 21), and group D (≥21).Results: In the dyspnea group, group A (n = 28) showed the following findings: (i) the forced expiratory volume in 1 s was not correlated with the peak V°O2 (p = 0.288), (ii) the arterial oxygen tension (PaO2) slope (peak minus resting PaO2/ΔV°O2) was the steepest (p &lt; 0.0001) among all subgroups, (iii) reduced tidal volume (VT) was negatively correlated with respiratory frequency at peak exercise (p &lt; 0.0001), and (iv) a break point in exertional VT curve was determined in 17 (61%) patients in group A. In these patients, there was a significant negative correlation between bicarbonate ion (HCO3-) levels at peak exercise and VT level when the VT-break point occurred (p = 0.032). In group D (n = 46), HCO3- levels were negatively correlated with plasma lactate levels (p &lt; 0.0001). In all subgroups, the HCO3- level was negatively correlated with minute ventilation. The dyspnea subgroups showed no significant differences in the overall mean pH [7.363 (SD 0.039)] and Borg scale scores [7.4 (SD, 2.3)] at peak exercise.Conclusions: During exercise, ventilation is stimulated to avoid arterial blood acidosis and hypoxemia, but ventilatory stimulation is restricted in the setting of reduced respiratory system ability. These conditions provoke the exertional dyspnea in COPD. Although symptom levels were similar, the exertional pathophysiologic conditions differed according to residual exercise performance; moreover, COPD patients showed great inter-individual variability. An adequate understanding of individual pathophysiologic conditions using CPET is essential for proper management of COPD patients
