P16: Report on a Dementia Prevention Workshop Organized through Multidiscipline Intervention: An Examination of Intervention Approach through the Evaluation of Group Reminiscence Method and Mental Aspect

Objective:This is a report of a workshop for local residents organized by university researchers in various fields with the aim to develop a dementia prevention method. The five academic fields involved in the project are Health & Sports, Psychology, Food Nutrition, Music, and Nursing.Methods:Dementia Prevention Workshop took place once a week between October 2021 and July 2022 except for some intervals due to surges in Covid-19 infection cases. Dual task exercises were conducted at each session, followed by groupworks by researchers of Psychology, Nutrition, Music, and Nursing Science taking turns. Psychologists facilitated the understanding of assertion, nutritionists held lectures on food life designed for dementia prevention, musicians played instruments, and nurses intervened through the Group Reminiscence Method. The Nursing Science experts conducted evaluations at the beginning and the end of each session using SF-36 and CES-D and checked the participants’ mood before and after the reminiscence session with Japanese UWIST mood adjective checklist (JUMACL).Results:16 participants took the measurement after the workshop, and their average age (SD) was 72.9 (5.5). In the overall evaluation, the participants’ motor ability improved(p<.05), and they retained cognitive functions. In SF-36, no statistically significant differences were observed before and after the classroom. Compared to the data from 2017, the scores in the social aspect were lower. In CES-D, the scores significantly worsened after the workshop, with some participants’ scores exceeding 16 points, which is the depression cutoff point. In JUMACL, the Tense Arousal (TA) related to the arousal state and the Energetic Arousal (EA), which is supposedly related to intellectual activities, both improved after the session.Conclusion:In a single evaluation before and after a group reminiscence session, the state of relaxed concentration with a suggested connection with intellectual activities, but the overall evaluation result throughout the workshop project suggested the need to reinforce the approach to the mental aspect because of some participants observed with decreased scores in the mental aspects with depressive tendency. We will establish an intervention plan by also incorporating the impact of Covid-19-related depression.

The Impact of Nursing Handover on Nurses’ Mood

Objective: To estimate the impact of nursing handover on nurses’ mood after the end of the nursing shift report. Methods: A cross-sectional, repeated-measures design study involving a diary questionnaire was conducted during November - December 2019. Data were collected from 125 nurses working in a public hospital in Northern Greece. 375 diaries were returned. Mood change was measured using the UWIST Mood Adjective Checklist instrument that describes three mood factors (Hedonic Tone, Tense Arousal and Energetic Arousal). Results: A significant change in nurses’ mood before and after the nursing handover was reported and more specifically, an increase in positive and a decrease in negative mood state was observed. A change in all mood groups - Hedonic Tone, Tense Arousal and Energetic Arousal was also identified. Nurses with many years of experience who work in internal medicine, increased their Hedonic Tone (P=0.001) and decreased their Tense Arousal (P=0.005). Conclusion: The benefits of nursing handover are long established and is suggested as the most appropriate period of time for nurses to achieve emotional change before leaving from work. Nurses are advised to use the nursing handover as an opportunity to psychologically disengage from work and increase their positive mood.

Strength of excitation and insomnia as mediated by mood dimensions.

The main goal of our study was to demonstrate the relationship between the strength of excitation (SE) as one of the basic central nervous system (CNS) properties and insomnia, and to determine the role of the mood components as mediators of this relationship. We hypothesized that SE directly and indirectly via arousal-related mood dimensions may be related to insomnia. The study involved 149 people, 85 women and 64 men, aged 18 to 60 (M = 30.11, SD = 11.43) selected from the general population using snowball sampling. The basic properties of the CNS were diagnosed using Pavlovian Temperament Survey. Mood was assessed using the Polish adaptation of UWIST Mood Adjective Checklist. To evaluate insomnia symptoms Athens Insomnia Scale in its Polish adaptation was used. SE negatively correlated with insomnia (no significant correlations between strength of inhibition and mobility and insomnia). All CNS properties positively correlated with hedonic tone (HT) and energetic arousal (EA), and negatively with tense arousal (TA) as mood dimensions. HT and EA were negatively correlated with insomnia but TA positively correlated with insomnia. Both EA and TA served as mediators in the relationship between SE and insomnia. The results indicated the relationship between SE and insomnia as well as between SE and EA and TA as mood dimensions related to arousal. Mediation analysis suggests that both EA and TA may serve as mediators of the relationship between SE and insomnia. However, the results of the mediation analysis require careful interpretation.

The Effect of Low Frequency Sound on Heart Rate Variability and Subjective Perception: A Randomized Crossover Study.

Background: Vibroacoustic therapy (VAT) uses low-frequency sound, often combined with listening to music, for therapeutic purposes. However, the impact of low-frequency vibration (LFV) on physiological functions and subjective perception is relatively unknown. Methods: We conducted a randomized cross-over study with the aim of comparing the effect of constant LFV of 40 Hz, its amplitude modulation, and the placebo condition on heart rate variability (HRV), stress perception (measured by visual analogue scales for stress) and mood (measured by UWIST Mood Adjective Check List). Results: Research experiments with various interventions (constant LFV with sound of nature (river in forest), amplitude modulation of the same LFV with sounds of nature and sounds of nature without LFV) were realised involving 24 participants. It was found there was an effect on HRV, stress perception and mood after the interventions. However, there were only seldomly experienced, and mostly nonsignificant, differences between the intervention conditions, so the effects may be attributed to factors other than LFV. Conclusions: Large scale experimental studies are needed to verify the preliminary findings and to explore various coinciding factors that may have influenced the results of this study, e.g., type of autonomic nervous system. We propose that the effect of LFV exposure may differ when combined with listening to music, and this hypothesis should be investigated in future studies.

Stuck in painful time: perception of time by individuals with eating disorders depending on their mood

Introduction: Eating disorders still pose a formidable challenge to health care professionals. The suffering of eating-disordered individuals may be profound, with the main contributing factors being low self-esteem, guilt and depression, a sense of hopelessness, and loneliness. The objective of the study was to determine how patients with eating disorders perceive time, and in particular whether their experience of time differs from that of healthy individuals. Another goal was to examine the relationship between the mood of the subjects and their time perspective. Materials and methods: The subjects were 30 women with eating disorders and 30 age-matched healthy female controls. The three measures applied were: the Time Metaphors Questionnaire by Małgorzata Sobol-Kwapińska, the Time Perspective Inventory by Philip Zimbardo, and the UWIST Mood Adjective Checklist (UMACL) by Gerald Matthews et al. Results: As expected, statistical analyses revealed that women with eating disorders were characterised by a more negative perception of time than healthy subjects. The study also confirmed the expected correlations between positive and negative time perceptions and mood. Conclusion: The results appear to have a considerable scholarly and practical value, and should be used in the psychotherapy of eating-disordered individuals focusing on existential aspects, including in particular topics regarding the experience of time by sufferers.

Influences of Lavender Essential Oil Inhalation on Stress Responses during Short-Duration Sleep Cycles: A Pilot Study.

Lavender essential oil (LEO) was reported to improve sleep quality. We investigated the influence of aromatherapy by testing the effects of LEO on stress responses during a short-duration sleep in a single-blind, randomized, crossover trial. The subjects were twelve healthy adults who were nonsmokers without any known disease and who were not prescribed medications, and nine of these completed the study. After the subjects had fallen asleep, they were sprayed with LEO using an aroma diffuser. Before and after 90 min of sleep, α-amylase, chromogranin A (CgA), and cortisol levels in saliva were measured as objective stress indicators, and the Japanese version of the UWIST Mood Adjective Checklist was used as a subjective indicator. A comparison of changes before and after sleep, with and without LEO, revealed that the cortisol level did not significantly change; however, α-amylase (p < 0.05) and CgA (p < 0.01) levels significantly decreased after LEO inhalation. A mood test indicated no change in mood before and after sleep, with or without LEO. Since α-amylase and CgA reflect the sympathetic nervous system response, these results indicate that LEO aromatherapy during a short-duration sleep cycle suppresses the stress response, especially that of the sympathetic nervous system.

Color aesthetics: A transatlantic comparison of psychological and physiological impacts of warm and cool colors in garden landscapes

Evidence shows green space exposure has beneficial impacts on psychological and physiological wellbeing. However, aesthetic differences in color use in cultivated garden landscapes on wellbeing remains unexplored. This study investigates how warm and cool colored garden landscapes affect psychological and physiological wellbeing and how responses differ geographically.Our between subjects design used USA and UK participants exposed to videos of static garden landscapes consisting of (a) warm colors, (b) cool colors and (c) control images. Measures of subjective psychological wellbeing (UWIST Mood Adjective Checklist (MACL)) and biometrics of stress using the Empatica E4 watch (Heart rate; Heart Rate Variability (HRV); Skin Temperature; Galvanic Skin Response (GSR) and Photoplethysmography) were obtained to ascertain if warm and cool colored cultivated garden landscapes affected psychological and physiological responses.Results showed statistical differences between locations in psychological and physiological wellbeing. USA participants experienced increases in hedonic tone and decreases in perceived stress after viewing warm and cool colored garden landscapes, a result not found in UK participants. Physiological indicators show geographical differences with beneficial effects of warm colors in the USA, shown in HRV and GSR measures relative to control. The UK sample presented mixed evidence regarding positive effects of warm and cool colored garden landscapes on physiological measures.These findings show stronger psychological and physiological responses to color in the US sample compared to a UK sample, suggesting geographic disparities in these responses to plant color. This should be further explored to understand color choice for landscape design to optimize outdoor settings that maximize wellbeing.

Changes of Mood and Cognitive Performance before and after a 100 km Nighttime Ultramarathon Run.

Ultramarathons are becoming an increasingly popular endurance sport. Year after year, the demands on athletes’ skills and endurance increase. Ultramarathons are particularly taxing on athletes’ psychological functioning. This study assessed the relationships between taking part in a nighttime ultramarathon and changes in mood and cognitive functioning. The study included 20 experienced runners aged 26–57 (M = 37.29; SD = 7.94) who had M = 7.08, SD = 5.41 (range 3–44) years of experience running. There were 18 men and 2 women. The mood states were measured twice, just before the start of the run and shortly after crossing the finish line, using the Polish version of the UMACL UWIST Mood Adjective Checklist by Mathews, Chamberlain, and Jones. To assess cognitive functioning, the Stroop Color and Word Test and “Forward digit span” subtest from the Wechsler Adult Intelligence Scale were used. We observed statistically significant changes in the mood of the runners: tense arousal, associated with the experienced stress, was significantly higher before the run than immediately after the finish. Moreover, we observed an improvement in cognitive functioning after finishing the 100 km run on both of the trials on the Stroop color word test and on the forward digit span test.

Cycling Without Age: Assessing the Impact of a Cycling-Based Initiative on Mood and Wellbeing.

Objective: Cycling Without Age is a global initiative in which trained volunteers take adults living in care homes or supported housing environments out on specially designed trishaws. Despite its global success, there is limited research on the effect the initiative has on the older adults taking part. The current study therefore assessed changes in mood and wellbeing to determine whether there were short-term benefits of participation. Methods: Forty-nine older adults (69% female; 67–100 years old (M = 84.1, SD = 7.6)) living in care homes and supported housing environments were recruited; 35 participants completed all measures and comprise the analytical sample. Participants completed the Warwick-Edinburgh Mental Wellbeing Scale and UWIST Mood Adjective Checklist immediately before a ride (baseline); they repeated the measures on completion of the ride (follow-up). Participants also completed baseline and follow-up measures on a day in which they did not go on a ride. Mixed ANOVA compared differences in baseline and follow-up mood and wellbeing scores on ride and no ride days. Results: For all mood and wellbeing measures, there were significant interactions between day (ride or no ride) and measurement occasion (baseline or follow-up). Analyses revealed significant improvement in mood and wellbeing at follow-up on ride days versus no ride days. Conclusion: Short-term positive changes in mood and wellbeing were reported as a result of participation in the Cycling Without Age initiative for older adults in care home and supported living environments. Further research is needed to explore the longevity of benefits and longer-term changes.

The Mental Health Benefits of Purposeful Activities in Public Green Spaces in Urban and Semi-Urban Neighbourhoods: A Mixed-Methods Pilot and Proof of Concept Study.

Access and exposure to public green space might be critical to health promotion and prevention of mental ill health. However, it is uncertain if differential health and mental health benefits are associated with undertaking different activities in public green space. We evaluated the health and wellbeing benefits of different activities in different locations of public green spaces in urban and semi-urban areas. We used a mixed-methods before-and-after design. Volunteers at three conservation sites were recruited and took part in group guided walks, practical conservation tasks or citizen science. Repeated measures one-way ANOVAs with Bonferroni correction assessed the relationship between location and activity type on change in acute subjective mood from pre- to post-activity, measured with the UWIST Mood Adjective Checklist (UWIST-MACL). Qualitative semi-structured interviews were undertaken and analysed thematically to explore participants’ perceptions about the health and wellbeing benefits of activities in public green space. Forty-five participants were recruited, leading to 65 independent observations. Walking, conservation and citizen science in public green space were associated with improved mood. Across all participants acute subjective mood improved across all domains of the UWIST-MACL. There was a significant association between reduction in stress and location (p = 0.009). Qualitatively participants reported that conservation and citizen science conferred co-benefits to the environment and individual health and well-being and were perceived as purposeful. Undertaking purposeful activity in public green space has the potential to promote health and prevent mental ill health.

Correlates and Predictors of Self-Assessments of Health and Physical Fitness Among Female Participants of University of the Third Age Classes

Abstract Introduction . We tested how female University of the Third Age (U3A) attendees evaluated their health, physical fitness, and satisfaction with health. We also examined various factors potentially underlying those self-assessments, that is objective indicators of health and physical fitness, their potential determinants (age and financial situation), and potential modifiers of self-assessment (mood, perceptive ability, and education). Material and methods . A total of 116 female participants attending U3A classes in Warsaw aged 50-88 years evaluated their health and fitness on a 100-level visual scale and their satisfaction with their health on a five-level Likert scale. Each participant completed the UWIST mood adjective checklist (UMACL) by Matthews, Chamberlain, and Jones and Yesavage’s geriatric depression scale, underwent the Fullerton fitness test, a hand grip strength test, Romberg’s test, and Ciechanowicz and Stanczyk’s attention and perception test, as well as filling out a specially designed questionnaire. Results . Self-assessments of health were found to correlate with aggravated symptoms of depression and certain components of physical fitness, but not with age or financial situation. Self-assessments of physical fitness, in turn, were strongly correlated with objective indicators of physical health and depression and less strongly with dexterity test results. General satisfaction levels, in turn, were found to be associated with long-term conditions, aggravated symptoms of depression, and financial situation. Conclusions . Overall, our results confirm that self-assessments are a moderately accurate indicator of the general health and physical fitness of elderly people: they correlated to a certain degree with more objective indicators of health/fitness but were influenced by modifying factors, particularly cognitive ones.

Affective Temperaments, Mood, and Insomnia Symptoms in a Nonclinical Sample

ABSTRACTObjective: The aim of the study was to understand the relationship between affective temperaments and insomnia symptoms and to examine mood state as a mediator in this relationship. Participants: The sample consisted of 659 adults (428 women and 231 men), aged 18–77 years old, derived from a nonclinical population. Methods: Affective temperaments were assessed using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A). Mood was measured using the UWIST Mood Adjective Checklist (UMACL). Insomnia was evaluated by the Athens Insomnia Scale. Results: We found positive correlations among anxious, cyclothymic, depressive, and irritable affective temperaments and insomnia symptoms. Negative correlation with insomnia symptoms was found for hyperthymic temperament. Energetic arousal and tense arousal, as mood dimensions, positively correlated with insomnia symptoms. Hierarchical regression analysis indicated that anxious, cyclothymic, and hyperthymic temperaments were significant predictors of insomnia symptoms. Mediation analyses indicated that anxious, cyclothymic, and hyperthymic temperaments affected insomnia symptoms, both directly and indirectly, through energetic arousal as a mediator. Conclusions: The results showed a relationship between affective temperaments and insomnia symptoms and included the role of energetic arousal, a mood state dimension, as a mediator.

Effects of Music therapy on psychological aspects of family-caregivers and care staffs in palliative care ward as a pilot study

Abstract Objective: The present study examined effects of music therapy on mood and healing sense of family-caregivers and staffs in a palliative care ward and their relationships in order to elevate well-being. Method: This study is a cross-sectional study. Participants were 25 family caregivers and staffs related to patients in a palliative care ward in Japan. The professional Jazz pianist played piano at live concert once and the audience sang in one session. Participants completed the Japanese UWIST Mood Adjective Check List (JUMACLE) consisted of Tension Arousal (TA) and Energetic Arousal (EA) pre and post music therapy, the Healing questions, and comments of this therapy only post. Results: The TA score significantly decreased from 18.3 to 14.6 (p<0.05), and the EA score significantly increased from 32.1 to 35.1 (p<0.05). The mean healing questions scores was 4.5 point of total 5 point. The healing score significantly correlated with EA (r=.46, p<.05), but not with TA. Conclusion: The music therapy focused on Jazz music decreased tension or anxiety and increased vigor or energy, and healing sense related to vigor. Music therapy in a palliative care for family-caregivers and staffs may be useful to promote their well-being.

The Effect of Dog-Assisted Intervention on Student Well-Being, Mood, and Anxiety

This novel, exploratory study investigated the effect of a short, 20 min, dog-assisted intervention on student well-being, mood, and anxiety. One hundred and thirty-two university students were allocated to either an experimental condition or one of two control conditions. Each participant completed the Warwick–Edinburgh Mental Well-Being Scale (WEMBS), the State Trait Anxiety Scale (STAI), and the UWIST Mood Adjective Checklist (UMACL) both before, and after, the intervention. The participants in the experimental condition interacted with both the dogs and their handlers, whereas the control groups interacted with either the dog only, or the handler only. The analyses revealed a significant difference across conditions for each measure, with those conditions in which a dog was present leading to significant improvements in mood and well-being, as well as a significant reduction in anxiety. Interestingly, the presence of a handler alongside the dog appeared to have a negative, and specific, effect on participant mood, with greater positive shifts in mood being witnessed when participants interacted with the dog alone, than when interacting with both the dog and the handler. These findings show that even a short 20 min session with a therapy dog can be an effective alternative intervention to improve student well-being, anxiety, and mood.

Time Perspectives Predict Mood States and Satisfaction with Life over and above Personality.

The present study aimed to test the incremental validity of Time Perspective (TP) scales in predicting satisfaction with life and mood, over and above the Big Five personality traits. It also investigated whether the new TP construct of Future Negative perspective contributed to prediction of these outcomes. Participants (N = 265) completed four measures: Satisfaction With Life Scale (SWLS), UWIST Mood Adjective Checklist (UMACL), a modified Zimbardo Time Perspective Inventory (ZTPI), and NEO-Five Factor Inventory (NEO-FFI). Results confirmed the incremental validity of TP, although Big Five dimensions were independently predictive of life satisfaction and certain mood scales. Past Negative TP was the strongest single predictor of life satisfaction. However, Future Negative TP was be the strongest mood predictor from the TP universe, after controlling for the Big Five and remaining TP dimensions. Findings suggest that TP is an important aspect of personality for understanding individual differences in well-being.

The analysis of anxiety and mood in healthy late-reproductive-stage women with regard to hormonal and genetic factors.

The purpose of this study was to determine whether anxiety and mood disorders in late-reproductive-stage women are related to the serotonin transporter and monoamine oxidase A gene polymorphisms. Research instrument used in this study were the State-Trait Anxiety Inventory and the UWIST Mood Adjective Checklist. The 44-bp VNTR polymorphism in the 5-HTT (SLC 6A4) promoter region and the 30-bp VNTR polymorphism in the MAO-A promoter region were analyzed. The study included 345 healthy Polish women in the late reproductive stage. The mean age of the participants was 42.3 ± 4.5 years. State anxiety was observed in 16.8 % of the women and trait anxiety in 14.5 %. There were no statistically significant differences in the mood and the mean levels of anxiety depending on the presence of the polymorphisms analyzed in this study. Depressed mood is frequent among healthy women in the late reproductive stage. Anxiety is definitely less common. The study did not demonstrate the relationship between the 5-HTT and MAO-A gene polymorphisms, and the severity of anxiety and mood disorders in healthy late-reproductive-stage women.

The Role of Morningness and Endurance in Mood and Attention During Morning and Evening Hours

Abstract. This study aimed at testing the effects of morningness-eveningness and endurance on mood and selective attention during morning and evening hours. University students (N = 80) completed the Polish version of the Morningness-Eveningness Questionnaire, the Formal Characteristics of Behaviour-Temperament Inventory, and two testing sessions scheduled during the morning and evening hours. Each testing session consisted of completing the UWIST Mood Adjective Checklist composed of three scales: energetic arousal (EA), tense arousal (TA), and hedonic tone (HT), and a computerized visual search task. Without consideration of morningness and endurance, a time-of-day effect appeared in the visual attention but not in affect: participants were more accurate and faster in the evening than in the morning. Considering morningness and endurance, neither of them influenced the selective attention but they did influence mood. Morningness influenced diurnal variations in EA and HT in such a way that from morning to evening hours, morning chronotypes showed a decrease and evening types an increase in EA and HT. During morning hours, morningness was related to higher EA and HT and lower TA, but endurance was not. During evening hours, morningness was unrelated to mood, but endurance was linked to higher EA. It is concluded that morningness and endurance impact mood differently throughout the day, with the role of morningness decreasing and the role of endurance increasing as the day progresses.

Visuospatial Ability as a Predictor of Novice Performance in Ultrasound-guided Regional Anesthesia

Visuospatial ability correlates positively with novice performance of simple laparoscopic tasks. The aims of this study were to identify whether visuospatial ability could predict technical performance of an ultrasound-guided needle task by novice operators and to describe how emotional state, intelligence, and fear of failure impact on this. Sixty medical student volunteers enrolled in this observational study. The authors used an instructional video to standardize training for ultrasound-guided needle advancement in a turkey breast model and assessed volunteers' performance independently by two assessors using composite error score (CES) and global rating scale (GRS). The authors assessed their "visuospatial ability" with mental rotation test (MRT), group embedded figures test, and Alice Heim group ability test. Emotional state was judged with UWIST Mood Adjective Checklist (UMACL), and fear of failure and general cognitive ability were judged with numerical reasoning test. High CES scores (high error rate) were associated with low MRT scores (ρ = -0.54; P < 0.001). Better GRS scores were associated with better MRT scores (ρ = 0.47; P < 0.001). Regarding emotions, GRS scores were low when anxiety levels were high (ρ = -0.35; P = 0.005) and CES scores (errors) were low when individuals reported feeling vigorous and active (ρ = -0.30; P = 0.01). An MRT predicts novice performance of an ultrasound-guided needling task on a turkey model and as a trait measure could be used as a tool to focus training resources on less-able individuals. Anxiety adversely affects performance. Therefore, both may prove useful in directing targeted training in ultrasound-guided regional anesthesia.

Development of the Emotion and Arousal Checklist (EACL)

We developed the 33-item Emotion and Arousal Checklist (EACL), which consisted of five subscales to assess emotions (Fear, Anger, Sadness, Disgust, and Happiness) and four subscales to assess arousal (Energetic arousal + Energetic arousal -, Tense arousal+, and Tense arousal -). This checklist was developed to assess psychological state, both at a given moment and during the past week. In Study 1, confirmatory factor analyses identified nine subscales, whose internal consistency was indicated by their reliability. In Study 2, the EACL's validity was demonstrated by its correlation with the State-Trait Anxiety Inventory, Multiple Mood Scale, General Arousal Checklist, Japanese UWIST Mood Adjective Checklist, and Profile of Mood States. In Study 3, changes caused by tasks that involved either reading emotion-inducing articles or performing a calculation indicated the validity of the EACL for measuring psychological state at a given moment. Further, the test-retest reliability of the EACL for assessing psychological state during the past week was confirmed. These studies confirmed the reliability and the validity of the EACL.

Differential Language Functioning of Monolinguals and Bilinguals on Positive-Negative Emotional Expression.

The present interdisciplinary research investigates the differential emotional expression between Persian monolinguals and Persian-English bilinguals. In other words, the article was an attempt to answer the questions whether bilinguals and monolinguals differ in the expression of positive and negative emotions elicited through sad and happy autobiographies and measured through UWIST Mood Adjective Checklist. The result of this pioneering work indicated no significant difference between Persian monolinguals and Persian-English bilinguals in expressing happy memories while differences were observed on sad memories. Bilinguals expressed more negative emotions in their L2 than L1. This outcome support the dominant claim that second language is the preferred language for the expression of sad emotions since it is the language of emotional detachment and distance. Further analysis on the number of words bilinguals and monolinguals used to express both sad and happy autobiographies indicated that bilinguals used more words in expressing both sad and happy autobiographies.
