    During the last decades, the increase in the rate of children and adolescents that are overweight or obese is alarming and it is related with a lower social competency, and low self-esteem. A transversal study was conducted with a representative sample of 292 students enrolled in years 8 and 9 at secondary school (13.05±0.97 years) in the city of Jaen, Spain. Girls wanted a thinner figure than boys (P < .001). Regarding self-esteem we observed statistically lower values in the case of girls (P < .000) as compared to their male counterparts. Regarding the BMI, students with a healthy weight have a statistically higher self-esteem score than students that are overweight and these have a slightly higher score than those that are obese. Positive correlation exists between the perceived silhouette and the desired silhouette (r=.485) and a negative correlation between the BMI and self-esteem (r=-.248). It is necessary to plan actions aimed as reinforcing and increasing self-esteem, focusing on the group of girls and the group of young adults with overweight and obesity problems.

    Full Text Available Screening for kidney diseases by urinalysis in school children is being conducted in many parts of the world with inexpensive tools such as urinary dipsticks. We conducted this study to know the prevalence of asymptomatic proteinuria in school children (age group 12-14 years in Kashmir valley as no previous study is available. After applying exclusion criteria, 2068 children were screened for proteinuria by dipstick method. Another test was performed in the children with abnormal findings in the first sample with dipstick of the same brand, after a period of one-month. These children were also assessed by timed urine collection (i.e., 24 h urinary protein. In the first dipstick test, the prevalence of proteinuria in the studied population was 6.2% which persisted in 2.17% after second dipstick examination. No child in the studied group was found to have glycosuria. In our study, no statistically significant association was found between proteinuria and gender, body mass index, or hypertension. In our study, the prevalence of persistent proteinuria in school children (age group 12-14 years in Kashmir valley was almost similar to the studies conducted in different parts of the world.

    In this study, the authors compared differences in sexual risk attitudes and intentions for three groups of youth (experimental program, n = 90; attention control, n = 80; and nonparticipant control, n = 634) aged 12-14 years. Two student groups participated with their parents in programs focused on strengthening family interaction and prevention of sexual risks, HIV, and adolescent pregnancy. Surveys assessed students' attitudes and intentions regarding early sexual and other health-risk behaviors, family interactions, and perceived parental disapproval of risk behaviors. The authors used general linear modeling to compare results. The experimental prevention program differentiated the total scores of the 3 groups (p < .05). A similar result was obtained for student intentions to avoid sex (p < .01). Pairwise comparisons showed the experimental program group scored higher than the nonparticipant group on total scores (p < .01) and on students' intention to avoid sex (p < .01). The results suggest this novel educational program involving both parents and students offers a promising approach to HIV and teen pregnancy prevention.

    Full Text Available Marijuana initiation during adolescence, and early adolescence in particular, is associated with adverse health consequences. Our study used 2005-2014 data from the annual, cross-sectional National Survey on Drug Use and Health to study the prevalence and correlates of marijuana initiation, use, and marijuana use disorder (MUD; abuse or dependence among 12- to 14-year olds living in civilian US households (n = 84 954. Examined correlates included age, sex, race/ethnicity, poverty status, metropolitan status, year of survey, depression, tobacco use, alcohol use, and fighting at school. Sex differences in the correlates of lifetime use and past year marijuana initiation were tested via interaction. Lifetime prevalence of marijuana use was 5.5%; 3.2% reported past year initiation. About 1 in 6 (16.8% past year initiates progressed to MUD within 12 months of first use. Although men had higher prevalence of lifetime use than women, past year initiation did not differ by sex. On examining the sex*race/ethnicity interaction effects, findings determined that non-Hispanic black and Hispanic men had higher prevalence estimates of ever using marijuana and incidence of past year initiation as compared with non-Hispanic white men; these race/ethnicity differences were not found among women. Identifying correlates of initiation and progression to MUD among young adolescents is critical to improve prevention and treatment program targets.

    Full Text Available A retrospective study was made of sports injuries occurring in physical education classes in 51 junior and senior high schools in Israel during a period of 14 months (2000-2002. The survey covered a total population of 11439 students aged 12 to 18, 52% male, 48% female. The aim of the study was to assess the incidence, types and risk factors involving sports injuries among students in physical education classes. Physical education teachers were asked to complete questionnaires recording injuries that occurred during their lessons. Data included: socio-demographic parameters (gender, age, height and weight of the injured students, area and type of injury, time of injury during the class, type of sport activity, previous injuries, assessment of sport capabilities and performance. A total of 192 injuries were recorded in the survey (1.70%. Male and female students had fairly similar injury rates (49% female, 51% male. 12-14 year old students showed the greatest number of injuries (52%. The ankle was the most common site of injury in both genders (48% mostly involving ankle sprain. Athletics was the most common sport involving injury (38%. 45% of injuries were reported to occur in the start of the class, whereas 26% of injuries were repeat injuries. This survey showed that the incidence of injuries during supervised physical education classes in high schools in Israel is relatively low and is similar to that of other Western countries.

    This paper describes the decision-making process used by the forecasters in the National Meteorological Center`s (NMC`s) Meterolological Operations Division and in Weather Forecast Offices of the National Weather Service to provide the successful forecasts of the superstorm of 12-14 March 1993. This review illustrates (1) the difficult decisions forecasters faced when using sometimes conflicting model guidance, (2) the forecasters` success in recognizing the mesoscale aspects of the storm as it began to develop and move along the Gulf and East Coasts of the United States, and (3) their ability to produce one of the most successful heavy snow and blizzard forecasts ever for a major winter storm that affected the eastern third of the United States. The successful aspects of the forecasts include the following. (1) Cyclogenesis was predicted up to 5 days prior to its onset. (2) The unusual intensity of the storm was predicted three days in advance, allowing forecasters, government officials, and the media ample time to prepare the public, marine, and aviation interests to take precautions for the protection of life and property. (3) The excessive amounts and areal distribution of snowfall were prediceted two days in advance of its onset. (4) An extensive number of blizzard watches and warnings were issued throughout the eastern United States with unprecedented lead times. (5) The coordination of forecasts within the National Weather Service and between the National Weather Service, private forecasters, and media meteorologists was perhaps the most extensive in recent history.

    To ensure the oral health of a population, clinicians must deliver appropriate dental services, and local communities need to have access to dental care facilities. However, establishment of this infrastructure must be based on reliable information regarding disease prevalence and severity in the target population. The aims of this study were to measure the incidence of dental caries in school children aged 12-14 throughout Qatar, including the influence of socio-demographic factors. A cross-sectional study was conducted in Qatar from October 2011 to March 2012. A total of 2113 children aged 12-14 were randomly selected from 16 schools located in different geographic areas. Three calibrated examiners using World Health Organization (WHO) criteria to diagnose dental caries performed the clinical examinations. Data analyses were subsequently conducted. The mean decayed, missing, and filled teeth index values were respectively 4.62 (±3.2), 4.79 (±3.5), and 5.5 (±3.7), for 12, 13, and 14 year-old subjects. Caries prevalence was 85%. The mandibular incisors and canines were least affected by dental caries, while maxillary and mandibular molars exhibited the highest incidence of dental caries. Dental caries were affected by socio-demographic factors; significant differences were detected between female and male children, where more female children showed dental caries than male children. In addition, children residing in semi-urban areas showed more dental caries than in urban areas. Results indicated that dental caries prevalence among school children in Qatar has reached critical levels, and is influenced by socio-demographic factors. The mean decayed, missing, and filled teeth values obtained in this study were the second highest detected in the Eastern Mediterranean region.

    2015-01-01

    Full Text Available Studies have shown that a positive attitude towards physical education (PE is in connection with students' engagement in PE classes and with the development of an active lifestyle. The objective of this study was to examine attitudes of early adolescent age students towards physical education, as well as to examine whether such attitudes vary with regard to gender, grade they attend and students' engagement in sport and physical exercises in extracurricular activities. The research was conducted on the sample of 531 students from 6th to 8th grade. The instrument Student's Attitudes toward Physical Education - SATPE was used to measure student's attitude towards PE. A special questionnaire was used to collect data on gender, grade and engagement in sport and physical exercising outside school. The results have shown that students have positive attitudes of moderate intensity towards physical education. MANOVA has shown that male students have more positive attitudes than female students, as well as that positivity of attitudes declines with age. Likewise, it was shown that students with more positive attitudes towards PE are more often engaged in physical exercises outside school. The connection between the attitude towards PE and involvement in organized sport was not confirmed. The paper presents suggestions for further research of students' attitude towards PE and its connection with physical activity of students.

    The aim of the study was to examine the relationships between various psychosocial factors and depressive symptoms in early adolescence. A representative sample of 2,465 12-14-year-old adolescents comprising 50.8% girls and 49.2% boys, with a mean age of 13.7 years, was recruited in two counties in Norway. The participation rate was 88.3%. Depressive symptoms were measured by the Mood and Feelings Questionnaire (MFQ). Correlations between the total sum of stressful events/daily hassles and the total sum of MFQ were moderately high, rs = .49 and rs = .53, respectively. Depressive symptoms were more strongly correlated with school-related stress among boys than girls, whereas the correlation between daily hassles and depressive symptoms was higher for girls than boys. The results of univariate analyses showed significantly higher mean total MFQ scores among adolescents not living with both natural parents, those who had moved more than twice and those with more than 3 siblings orhaving fewer than 2 close friends. Further, adolescents from Third World societies and adopted adolescents, those from lower SES groups, having unemployed parents or living in coastal areas had higher mean depressive symptom scores. The results of multiple regression analyses yielded the following six significant predictors of total MFQ scores in order of importance: Sum of daily hassles and sum of stressful life events, gender, number of friends, ethnicity and mother's employment status. Altogether, these variables accounted for 43% of the total variance in MFQ scores. It is concluded that these psychosocial predictors should be addressed when assessing depressive symptoms in early adolescence. The findings of the study are discussed in view of previous research in the field and their clinical significance.

    The present study is a detailed evaluation of age at smoking initiation among university male students in Kuwait based on a random sample of 664 students selected from all students during 1993. The Acturial Life Table analysis revealed that almost one tenth of the students initiated cigarette smoking between ages 16 and 17 with the rate of initiation increasing rapidly thereafter and reaching 30% by age 20 and almost 50% by the time they celebrate their 24th birthday. The most important environmental risk factor positively associated for smoking initiation was observed to be the history of smoking among siblings with a relative risk of 1.4. Compared to students of medicine and engineering, the students of other faculties revealed a higher risk in smoking initiation with an RR = 1.77 for sciences and commerce and 1.61 for other faculties (arts, law, education and Islamic studies). The analysis revealed a rising generation trend in cigarette smoking. There is a need for reduction of this trend among young adults in Kuwait and throughout other countries in the region.

    Objective: To determine the frequency of dental erosion in 12-14 years school children and its association with dietary habits. Study Design: Observational cross-sectional analytical study. Place and Duration of Study: Fatima Jinnah Dental College, Karachi, from January to June 2010. Methodology: School children aged between 12 - 14 years were included in this study. Dental erosion was detected by visual examination. Aself-developed questionnaire was used to assess the dietary habits of children. Acidic diet was considered a diet that has an acidic pH. The amount of consumption of acidic drinks and food per week was categorized into low consumption (1 - 7 times / week) and medium consumption (8 - 21 times / week). Chi-square test was applied to see any statistical difference between diet and tooth erosion at 95 percent CI. Results: The Results showed a high frequency of (46 percent) dental erosion in children, which was significantly higher (p < 0.001) in children with more acidic diet. Conclusion: This study highlights the impact of dietary habits on the prevalence of dental erosion in children. Acidic diets need to be controlled in frequency to prevent dental erosion. (author)

    Full Text Available Strive for peace with everyone? Hebrews 12:14 in perspective. What sounds like a simple exhortation in Hebrews 12:14 has caused a great deal of discussion amongst biblical scholars. Does the writer of Hebrews command his hearers to strive for peace with everyone everywhere, or is he exhorting them to strive for peace with all the members of their faith ommunity? Both interpretations have arguments for and against. The main arguments of both interpretations are the interpretation of the place of this exhortation in Hebrews, the meaning of the preposition μετά + genitive and the nuance of εἰρήνη within this context. This article tries to determine to whom the writer of Hebrews is referring with πάντων in 12:14 by doing thorough exegesis of this verse, and by so doing evaluating biblical scholar’s interpretation of πάντων. From this analysis certain implications are drawn for the first hearersand believers today.

    Full Text Available Depressive disorders are the most typical disease affecting many different factors of humanity. University students may be at increased risk of depression owing to the pressure and stress they encounter. Therefore, the purpose of this study is comparing the level of depression among male and female athletes and non-athletes undergraduate student of private university in Esfahan, Iran. The participants in this research are composed of 400 male and female athletes as well as no-athletes Iranian undergraduate students. The Beck depression test (BDI was employed to measure the degree of depression. T-test was used to evaluate the distinction between athletes and non-athletes at P≤0.05. The ANOVA was conducted to examine whether there was a relationship between level of depression among non-athletes and athletes. The result showed that the prevalence rate of depression among non-athlete male undergraduate students is significantly higher than that of athlete male students. The results also presented that level of depression among female students is much more frequent compared to males. This can be due to the fatigue and lack of energy that are more frequent among female in comparison to the male students. Physical activity was negatively related to the level of depression by severity among male and female undergraduate students. However, there is no distinct relationship between physical activity and level of depression according to the age of athlete and nonathlete male and female undergraduate students. This study has essential implications for clinical psychology due to the relationship between physical activity and prevalence of depression.

    Malocclusion, the body posture, and the breathing pattern may correlate, but this issue is still controversial. The aim of the study was to examine the relationship between the type of malocclusion, the body posture, and the nasopharyngeal obstruction in 12-14-year-old children. The study group consisted of 76 orthodontic patients (35 boys, 41 girls) aged 12-14 years (mean age, 12.79 years [SD, 0.98]). All the patients were examined by the same orthodontist (study model and cephalometric radiograph analysis), the same orthopedic surgeon (body posture examined from the front, the side, and the back), and the same otorhinolaryngologist (anterior and posterior rhinoscopy and pharyngoscopy) in a blind manner. The prevalence of a poor body posture and a nasopharyngeal pathology was high in the present study. In total, 48.7% of the orthodontic patients had a kyphotic posture and 55.3% a rib hump in the thoracic region. The nasopharyngeal pathology was diagnosed in 78.9% of the patients. The patients with the kyphotic posture had a higher mandibular plane angle (MP-SN) and a lower sagittal position of the mandible SNB angle. A deeper overbite correlated with shoulder and scapular asymmetry. The kyphotic posture was diagnosed in 55.0% of the patients with the nasopharyngeal pathology. The sagittal body posture was related to the vertical craniofacial parameters and hypertrophy of the tonsils and/or the adenoids. The study showed no relationship between the degree of crowding, the presence of a posterior cross bite, orthopedic parameters, and a breathing pattern.

    The aim of this study was to explore the modification of stereotypes and myths regarding aging among third-year nursing students before and after undergoing an Aging Nursing course. A within-subject repeated-measures descriptive study was conducted. The Negative Stereotypes Questionnaire about Aging (CENVE) was used. The overall prevalence of negative stereotypes was 62.0% pre-intervention (P1) and 12.3% post-intervention (P2) measured; these values were 63.5% (P1) and 9.2% (P2) for the health factor, 43.1% (P1) and 4.9% (P2) for the motivation and social factors and 58.3% (P1) and 3.8% (P2) for the character-personality factor. Paired Student's t tests confirmed that the differences were statistically significant. There was a high prevalence of negative stereotypes toward aging among the nursing students, even though they had conducted clinical practice and were in their third year. The course was demonstrated to be effective in modifying these stereotypes. The proper training of future professionals markedly contributes the dispensation of proper care and the eradication of ageism, which remains prevalent in the healthcare system.

    In this article the well-known passage in Joshua 10:12-14 is critically investigated within the context of the pericope of Joshua 10. A literary critical investigation shows, inter alia, that the oldest version of the pericope probably was a heroic saga of Joshua’s campaign, with the miraculous intervention of YHWH having been “written into” the narrative at a later stage. During the latter process a poetic fragment, the original of which is lost to us, was interpreted literally, thus creating a miracle account. This miracle account serves the main focus of the pericope: YHWH alone makes possible the impossible for his people.

    The Fourth International MELODI Workshop is organized by STUK - Radiation and Nuclear Safety Authority in Helsinki, Finland, on 12-14 September 2012. The workshop offers an update of recent low-dose research issues, and an opportunity to participate in the MELODI Low Dose Research Platform, a major step in the long term goals that the European Low-Dose Risk research intends to achieve. The main goal of MELODI is to develop and maintain a Strategic Research Agenda (SRA) in the field of low-dose radiation research, and to actively promote its implementation. DoReMi Network of Excellence funded by the European Commission is supporting the setting up of the Platform and addressing some of its research needs. In line with one of the main SRA goals, a major aim of the workshop was to set all topics in an interdisciplinary context. The Workshop abstracts cover plenary lectures as well as poster presentations related to topical discussions in breakout sessions. The theme of the first day 'Low dose risk research - state of the art' provides an introduction to the MELODI activities and the SRA and an update on recent epidemiological studies and dosimetric aspects of low dose studies. Potential implications of cardiovascular disease risk for radiation protection are also addressed. Discussion on the state-of-the art of MELODI SRA took place in three break-out groups addressing epidemiological approaches, cancer mechanisms and models and infrastructures and knowledge management. The second day 'Emerging scientific challenges' features the development of science and novel technologies, covering topics such as epigenetics, systems biology, stem cells as well as biomarkers that could be potentially used in molecular epidemiological studies. The associated breakout sessions explore the roadmap for future research, covering themes on biomarkers and biobanks, non-cancer effects, as well as low dose dosimetry and dose concept. The third day 'Integrating the research' provides

  19. Rac1 modification by an electrophilic 15-deoxy Δ12,14-prostaglandin J2 analog

    Directory of Open Access Journals (Sweden)

    S.B. Wall

    2015-04-01

    Full Text Available Vascular endothelial cells (ECs are important for maintaining vascular homeostasis. Dysfunction of ECs contributes to cardiovascular diseases, including atherosclerosis, and can impair the healing process during vascular injury. An important mediator of EC response to stress is the GTPase Rac1. Rac1 responds to extracellular signals and is involved in cytoskeletal rearrangement, reactive oxygen species generation and cell cycle progression. Rac1 interacts with effector proteins to elicit EC spreading and formation of cell-to-cell junctions. Rac1 activity has recently been shown to be modulated by glutathiolation or S-nitrosation via an active site cysteine residue. However, it is not known whether other redox signaling compounds can modulate Rac1 activity. An important redox signaling mediator is the electrophilic lipid, 15-deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2. This compound is a downstream product of cyclooxygenase and forms covalent adducts with specific cysteine residues, and induces cellular signaling in a pleiotropic manner. In this study, we demonstrate that a biotin-tagged analog of 15d-PGJ2 (bt-15d-PGJ2 forms an adduct with Rac1 in vitro at the C157 residue, and an additional adduct was detected on the tryptic peptide associated with C178. Rac1 modification in addition to modulation of Rac1 activity by bt-15d-PGJ2 was observed in cultured ECs. In addition, decreased EC migration and cell spreading were observed in response to the electrophile. These results demonstrate for the first time that Rac1 is a target for 15d-PGJ2 in ECs, and suggest that Rac1 modification by electrophiles such as 15d-PGJ2 may alter redox signaling and EC function.

    15-Deoxy-delta12,14-prostaglandin J2 (15d-PGJ2) is a potent ligand for peroxisome proliferators-activated receptor γ (PPARγ). However, its various effects independent of PPARγ have recently been observed. The effect of 15d-PGJ2 on neuronal cells is still controversial. We investigated its effect on neuronal cells (N18D3 cells). When N18D3 cells were treated with 15d-PGJ2, the viability was not changed up to 8 μM, but decreased at higher than 8 μM. The expressions of survival signals, such as p85a phosphatidylinositol 3-kinase, phospho-Akt, and phospho-glycogen synthase kinase-3 beta (Ser-9), slightly increased up to 8 μM, however, decreased at higher than 8 μM. The levels of free radicals and membrane lipid peroxidation and the expression of c-Jun N-terminal Kinase increased in a dose-dependent manner, especially at higher than 8 μM. However, the expressions of death signals, such as cytosolic cytochrome c, activated caspase-3, and cleaved poly(ADP-ribose) polymerase, decreased up to 8 μM, however, increased at higher than 8 μM. In the study to evaluate whether low dose of 15d-PGJ2, up to 8 μM, had protective effect on oxidative stress-injured N18D3 cells, compared to the cells treated with only 100 μM H 2 O 2 , the pretreatment with 8 μM 15d-PGJ2 increased the viability and the expressions of the survival signals, but decreased them of the death signals. These results indicate that 15d-PGJ2 could be a neuroprotectant or a neurotoxicant, depending on its concentration. Therefore, some specific optimum dose of 15d-PGJ2 may be a new potential therapeutic candidate for oxidative stress-injury model of neurodegenerative diseases

    Introduction Traditionally, Emergency Medical Services (EMS) educators have divided the pediatric population into age groups to assist in targeting their clinical and didactic curriculum. Currently, the accrediting body for paramedic training programs requires student exposure to pediatric patients based entirely on age without specifying exposure to specific pathologies within each age stratification. Identifying which pathologies are most common within the different pediatric age groups would allow educators to design curriculum targeting the most prevalent pathologies in each age group and incorporating the physiologic and psychological developmental milestones commonly seen at that age. Hypothesis It was hypothesized that there are unique clusterings of pathologies, represented by paramedic student primary impressions, that are found in different age groups which can be used to target provider education. This is a retrospective review of prospectively collected data documented by paramedic students in the Fisdap (Field Internship Student Data Acquisition Project; Saint Paul, Minnesota USA) database over a one-year period. For the purposes of this study, pediatric patients were defined arbitrarily as those between the ages of 0-16 years. All paramedic student primary impressions recorded in Fisdap for patients aged 0-16 years were abstracted. Primary impression by age was calculated and graphed. The frequency of primary impression was then assessed for significance of trend by age with an alpha ≤.05 considered significant. The following primary impressions showed clinically and statistically significant variability in prevalence among different pediatric age groups: respiratory distress, medical-other, abdominal pain, seizure, overdose/poisoning, behavioral, and cardiac. In patients less than 13 years old, respiratory and other-medical were the most common two primary impressions and both decreased with age. In patients 5-16 years old, the prevalence of

    Full Text Available Emotions are an integral part of “classroom life” and are experienced in teacher-student interactions quite often (Hosotani & Imai-Matsumura, 2011. The present study focuses on teachers’ emotions in classrooms. Its purpose is to establish which emotions are expressed by teachers in their interactions with students, the triggering situations of the two most frequent emotions, and their level of intensity and suitability. Teachers’ emotions were observed by students of primary education during their practical experience work, in grades one to five. They used a scheme constructed for observing different aspects of emotions. The observations of 108 teachers in 93 primary schools from various Slovenian regions were gathered. The results show that primary school teachers express various pleasant and unpleasant emotions, with unpleasant emotions prevailing. The average frequency of teachers’ emotion expression decreased from grade one to five. Anger was the most frequently expressed emotion (N = 261, followed by joy (N = 151. Teachers’ anger and joy were triggered in different situations: anger predominantly when students lacked discipline and joy predominantly in situations of students’ academic achievement. The intensity of expressed anger and joy was moderate in all five grades, while the assessed suitability of these two emotions was high.

    To explore the ageing stereotypes held by health students and faculty members in three health science schools in Chile. This cross-sectional study surveyed 284 students and faculty members from the dental, physical therapy and speech therapy schools of the University of Talca, Chile. A validated 15-question questionnaire about negative stereotypes was used (CENVE). The questions were divided into three categories: (i) health, (ii) social factors and motivation and (iii) character and personality. The scores for each category were grouped into the following categories: (i) positive, (ii) neutral and (iii) negative. Negative stereotypes were compared across genders, socio-economic status levels, classes, positions (student or faculty member) and schools. The majority of the participants held neutral stereotypes towards ageing, followed by positive perceptions. No differences were detected between the genders, schools or classes. While most of the students had neutral perceptions about ageing, the faculty's perceptions were rather positive (p = 0.0182). In addition, people of lower-middle socio-economic status held more positive stereotypes about ageing than the participants of high and middle status (p = 0.0496). Stereotypes about ageing held by health-related students and faculty members appear to be rather neutral. The stereotypes seem to be better among students with some clinical experience, students of lower socio-economic status and faculty members. © 2013 John Wiley & Sons A/S and The Gerodontology Society.

    2017-09-01

    The purpose of this study is to compare similarities and differences in the attitudes toward aging among college students from Taiwan and the United States; 128 Taiwanese students and 124 U.S. students participated in this study. The findings indicate that the majority of students from both countries viewed aging as consisting primarily of physical changes. The differences are the U.S. students' drawings showing physical decline along with hospitals, nursing homes, or death, whereas Taiwanese students presenting physical decline as getting wrinkles, wearing glasses, or needing aid devices. U.S. students associated aging with grandparents-grandchildren relationships, whereas more Taiwanese students thought aging related to spousal relationships. This study adds to the existing literature that demonstrates the strong influence of different cultures on students' attitudes toward aging. Further, knowledge derived from this study can be used in gerontology courses for both students and professors to lessen or correct ageist stereotypes over time.

    Full Text Available In many Business Schools today, accounting academics have been introduced to the concept of sustainabilitythat challenges the dominant 20th century way of doing business. In these schools, it is now reasoned that thepurpose of business may be better achieved if it involves taking decisions that recognize the holisticeconomic, social and environmental consequences of those decisions. Simply justifying decisions on the basisthat shareholders’ wealth will be maximized is now thought by many to be inadequate. We argue that this newperspective should not be taught to accounting students. Rather we argue that (following Aristotle studentsshould be exposed to arguments that encourage them to develop the virtue of “unfettered vigor”, comingfrom intelligent personal choice, which will help them recognize that “good living”, by themselves and theirdescendants, is dependent on the sustainable business perspective being adopted in society.

    To evaluate changes in empathy and perceptions as well as game experiences among student pharmacists participating in an aging simulation game. First-year student pharmacists participated in an aging simulation game. Changes were measured pre/post-activity using the Kiersma-Chen Empathy Scale (KCES) and Jefferson Scale of Empathy--Health Professions Scale (JSE-HPS) for empathy and the Aging Simulation Experience Survey (ASES) for perceptions of older adults' experiences and game experiences. Wilcoxon signed rank tests were used to determine changes. One hundred fifty-six student pharmacists completed the instruments. Empathy using the KCES and JSE-HPS improved significantly. Of the 13 items in the ASES, 9 significantly improved. Simulation games may help students overcome challenges demonstrating empathy and positive attitudes toward elderly patients.

    Residential aged care is an increasingly important health setting due to population ageing and the increase in age-related conditions, such as dementia. However, medical education has limited engagement with this fast-growing sector and undergraduate training remains primarily focussed on acute presentations in hospital settings. Additionally, concerns have been raised about the adequacy of dementia-related content in undergraduate medical curricula, while research has found mixed attitudes among students towards the care of older people. This study explores how medical students engage with the learning experiences accessible in clinical placements in residential aged care facilities (RACFs), particularly exposure to multiple comorbidity, cognitive impairment, and palliative care. Fifth-year medical students (N = 61) completed five-day clinical placements at two Australian aged care facilities in 2013 and 2014. The placements were supported by an iterative yet structured program and academic teaching staff to ensure appropriate educational experiences and oversight. Mixed methods data were collected before and after the clinical placement. Quantitative data included surveys of dementia knowledge and questions about attitudes to the aged care sector and working with older adults. Qualitative data were collected from focus group discussions concerning medical student expectations, learning opportunities, and challenges to engagement. Pre-placement surveys identified good dementia knowledge, but poor attitudes towards aged care and older adults. Negative placement experiences were associated with a struggle to discern case complexity and a perception of an aged care placement as an opportunity cost associated with reduced hospital training time. Irrespective of negative sentiment, post-placement survey data showed significant improvements in attitudes to working with older people and dementia knowledge. Positive student experiences were explained by in

    Full Text Available This study undertook a five month qualitative investigation into technology use amongst twelve high school social studies students in two different sites in the Midwestern United States. This study examined students’ use of technology and its relationship to three dimensions of citizenship in a global age: understand global events, issues, and perspectives, participate in global networks to communicate and collaborate with global audiences, and advocate on global problems and issues to think and act globally. Collecting data through semi-structured student interviews, online-threaded discussions and document analysis, I triangulated findings, and employed a qualitative approach. The study finds a relationship between student participants’ use of technology and their serving as engaged citizenship in a global age. In using technology, students accessed international news and information, joined global networks to communicate and collaborate with global audiences, and produced digital content for international audiences.

    Strategies to build a larger workforce of physicians dedicated to research on aging are needed. One method to address this shortage of physician scientists in geriatrics is short-term training in aging research for early-stage medical students. The authors examined the effects of two summer research training programs, funded by the National Institutes of Health, on medical students' attitudes toward aging, using the Carolina Opinions on Care of Older Adults (COCOA). The programs combined mentored research, didactics, and some clinical exposure. In a sample of 134 participants, COCOA scores improved significantly after completion of the research training program. There was a significant interaction of gender, such that female students had higher baseline scores than males, but this gender difference in COCOA scores was attenuated following the program. Four of the six COCOA subscales showed significant improvement from baseline: early interest in geriatrics, empathy/compassion, attitudes toward geriatrics careers, and ageism.

    Full Text Available In this study, two researchers explored student learning preferences in online courses. They used the scholarship of teaching and learning process as a research model, and embedded a web-based survey and online focus groups in the online courses they were teaching. After collecting data, the researchers conducted multiple logistic regression analyses to test their hypothesis that a relationship existed between some student factors and student preferences for types of online learning activities. The results of the data analysis revealed a statistically significant relationship between student age and student preference for certain types of online learning activities. Older students in the study indicated a much stronger preference for videos of the professor lecturing, while younger students tended to prefer more interactive learning strategies. Focus group comments from the older students provide insights into some of the reasons why they found watching video lectures to be helpful for their learning, and comments from younger students illustrate how they learn best in online courses. The researchers offer suggestions for online instructors based on the findings of this study, and they explain why online instructors may find the scholarship of teaching and learning research process especially helpful for both teaching and research efforts.

    As part of an effort by the Lunar Data Node (LDN) we are restoring data returned by the Apollo Dust, Thermal, and Radiation Engineering Measurements (DTREM) packages emplaced on the lunar surface by the crews of Apollo 11, 12, 14, and 15. Also commonly known as the Dust Detector experiments, the DTREM packages measured the outputs of exposed solar cells and thermistors over time. They operated on the surface for up to nearly 8 years, returning data every 54 seconds. The Apollo 11 DTREM was part of the Early Apollo Surface Experiments Package (EASEP), and operated for a few months as planned following emplacement in July 1969. The Apollo 12, 14, and 15 DTREMs were mounted on the central station as part of the Apollo Lunar Surface Experiments Package (ALSEP) and operated from deployment until ALSEP shutdown in September 1977. The objective of the DTREM experiments was to determine the effects of lunar and meteoric dust, thermal stresses, and radiation exposure on solar cells. The LDN, part of the Geosciences Node of the Planetary Data System (PDS), operates out of the National Space Science Data Center (NSSDC) at Goddard Space Flight Center. The goal of the LDN is to extract lunar data stored on older media and/or in obsolete formats, restore the data into a usable digital format, and archive the data with PDS and NSSDC. For the DTREM data we plan to recover the raw telemetry, translate the raw counts into appropriate output units, and then apply calibrations. The final archived data will include the raw, translated, and calibrated data and the associated conversion tables produced from the microfilm, as well as ancillary supporting data (metadata) packaged in PDS format.

    Full Text Available ABSTRACT   Introduction: Basic Health Research 2013 showed Dental Caries Index in school age student in West Java was lower than the expected target, with occlusal surface as most affected part. The purpose of this study was to determine the risk status of dental caries in school age student by using cariogram analysis. Methods: Observational research. Study was conducted on 30 student aged 11-12 years with caries high risk on occlusal surfaces. Purposive sampling was taken from students of SDN Cikawari and SDN Mekarjaya Bandung Regency with high DMF-S index. Inclusion criteria: male and female, aged 11-12 years, good systemic health, SDN Mekarjaya and SDN Cikawari Bandung Regency students. Exclusion criteria: suffering from systemic disorder, currently in long-term antibiotic therapy, orthodontic appliance usage. Case history, eating habits and intake of fluoride, caries experience, salivary volume and buffering capacity of each sample was examined using cariogram examination method. Results: The cariogram analysis showed 43% chance of caries avoidance. Diet control was 23.3%, includes two factors: sugary foods and eating frequency. Bacteria control was 11.9% by evaluating both bacterial factors (the amount of plaque and the bacteria Streptococcus mutans. Vulnerability control was 14.4%, including caries prevention by the continuation of fluorine program and other conditions control that affect salivary secretions. Conclusion: Based on cariogram analysis found that all samples who had occlusal surfaces caries were at a high risk category, but still having moderate potential of avoiding new caries occurrence by controlling risk factors.

    Full Text Available In this study, researchers wished to ascertain whether there were age (three- and four-year old, sibling (with or without older siblings, and sex (male and female differences in the use of relational aggression in preschool students as rated by peers and teachers. In order to answer this research question, two 2 × 2 × 2 factorial ANOVA procedures with the relational aggression composite score as the dependent variable on the PSBS-P and PSBS-T were used for peer and teacher assessment, respectively, of relational aggression. Results revealed that in the peer ratings of preschool students' relationally aggressive behavior, there was an disordinal age by sibling interaction, in which four-year-old children with siblings were significantly more likely to be rated by their peers as using relational aggression than three-year-old children without siblings. In the teacher ratings of preschool students' relationally aggressive behavior, a main effect for age was observed. Teachers rated four-year old children as evidencing significantly higher levels of relational aggression as compared to three-year-olds. No sex differences were observed in the use of relational aggression either at age three or age four in this sample. Implications for these findings are presented.

    The Optical Network Testbeds Workshop 2 (ONT2), held on September 12-14, 2005, was cosponsored by the Department of Energy Office of Science (DOE/SC) and the National Aeronautics and Space Administration (NASA), in cooperation with the Joint Engineering Team (JET) of the Federal Networking and Information Technology Research and Development (NITRD) Program's Large Scale Networking (LSN) Coordinating Group. The ONT2 workshop was a follow-on to an August 2004 Workshop on Optical Network Testbeds (ONT1). ONT1 recommended actions by the Federal agencies to assure timely development and implementation of optical networking technologies and infrastructure. Hosted by the NASA Ames Research Center in Mountain View, California, the ONT2 workshop brought together representatives of the U.S. advanced research and education (R&E) networks, regional optical networks (RONs), service providers, international networking organizations, and senior engineering and R&D managers from Federal agencies and national research laboratories. Its purpose was to develop a common vision of the optical network technologies, services, infrastructure, and organizations needed to enable widespread use of optical networks; recommend activities for transitioning the optical networking research community and its current infrastructure to leading-edge optical networks over the next three to five years; and present information enabling commercial network infrastructure providers to plan for and use leading-edge optical network services in that time frame.

    Fever is an important part of the host defense response, yet fever can be detrimental if it is uncontrolled. We provide the first evidence that 15-deoxy-Delta12,14-prostaglandin J2 (15d-PGJ2), an endogenous ligand for peroxisome proliferator-activated receptor gamma (PPARgamma), can attenuate the febrile response to lipopolysaccharide (LPS) in rats via an action on the brain. Furthermore, we show that PPARgamma is expressed in the hypothalamus, an important locus in the brain for fever generation. In addition, 15d-PGJ2 and its synthesizing enzyme (PGD2 synthase) were present in rat cerebrospinal fluid, and their levels were enhanced in response to systemic injection of LPS. The antipyretic effect of 15d-PGJ2 was associated with reduction in LPS-stimulated cyclooxygenase-2 expression in the hypothalamus but not in p44/p42 mitogen-activated protein kinase phosphorylation or in the expression of the PPARgamma. Thus it is likely that there is a parallel induction of an endogenous prostanoid pathway in the brain capable of limiting deleterious actions of the proinflammatory prostaglandin E2-dependent pathway.

    The present study investigated characteristics of the relative age effect (RAE) among a general sample of Japanese elementary and junior high school students. Japan applies a unique annual age-grouping by birthdates between April 1 and March 31 of the following year for sport and education. Anthropometric and physical fitness data were obtained from 3,610 Japanese students, including height, weight, the 50-m sprint, standing long jump, grip strength, bent-leg sit-ups, sit and reach, side steps, 20-m shuttle run, and ball throw. We examined RAE-related differences in these data using a one-way analysis of variance by comparing students with birthdates in the first (April-September) versus second (October-March of the following year) semesters. We observed a significant RAE for boys aged 7 to 15 years on both anthropometric and fitness data, but a significant RAE for girls was only evident for physical fitness tests among elementary school and not junior high school students. Thus, a significant RAE in anthropometry and physical fitness was evident in a general sample of school children, and there were RAE gender differences among adolescents.

    Using the Longitudinal Surveys of Australian Youth (LSAY) data, this paper aimed to examine if, and to what extent, demographic factors predict students' participation in science over the age of 16 (post-16). While all the students participating in this study are attending Australian schools, the comprehensiveness of these datasets, together with inclusion of studies from around the world provides a useful reference point for an international audience. Over 7000 students are included in the analysis of this paper. Characteristics of focus in this paper include groups who have been identified as being underrepresented in past studies including Indigenous students, those from lower-socio-economic status (SES) backgrounds, sex differences and immigrants. Among the factors tested, Indigenous status was the strongest negative predictor of post-16 science participation. SES was also a relatively strong predictor of post-16 science participation. Compared to students categorised with an Australian-ancestry, first-generation and foreign-background students were more likely to participate in post-16 science. The findings of this study contribute to existing research on debates about equity and trends in science participation.

    Full Text Available Introduction: Along with the rising life expectancy, there occurs an increased interest in geriatric care and in assessment of life quality in elderly persons. This study sought to examine the effects of physical activity on the quality of life in students of the University of the Third Age (UTA. Another purpose was to determine correlations between physical activity at a young age and the level of health state and physical activity at the time of the research as well as assessing the effects of socio-demographic factors on the quality of life in elderly individuals. Material and methods: The study included 138 UTA students (113 females and 25 males aged 50 and above from Warminsko-mazurskie region. The questionnaire consisting of two parts was applied as a research tool. The first part included the authors’ own questionnaire with general questions as well as questions regarding physical activity levels at a young age and at the time of the research. The second part was made up of the standardised WHOQOL-BREF questionnaire (shorter version of WHOQOL which was used to assess the subjects’ quality of life. Results: No significant differences between physical activity levels at a young age and at the time of the research were noted (p < 0.05. Self-evaluation of both life quality and heath state was significantly higher in individuals engaged in vigorous and moderate physical activity (p < 0.05 than in the other group. Conclusions: Physical activity of UTA students determines their quality of life and health state. Socio-demographic factors such as sex, age and a place of living influence the scores regarding the quality of life in WHOQOL-BREF domains.

    In courses where topics are sensitive or even considered taboo for discussion, it can be difficult to assess students' deeper learning. In addition, incorporating a wide variety of students' values and beliefs, designing instructional strategies and including varied assessments adds to the difficulty. Journal entries or response notebooks can highlight reflection upon others' viewpoints, class readings, and additional materials. These are useful across all educational levels in deep learning and comprehension strategies assessments. Journaling meshes with transformative learning constructs, allowing for critical self-reflection essential to transformation. Qualitative analysis of journals in a death and dying class reveals three transformative themes: awareness of others, questioning, and comfort. Students' journal entries demonstrate transformative learning via communication with others through increased knowledge/exposure to others' experiences and comparing/contrasting others' personal beliefs with their own. Using transformative learning within gerontology and geriatrics education, as well as other disciplined aging-related courses is discussed.

  15. Increasing the emotional engagement of first year mature-aged distance students: Interest and belonging

    2014-08-01

    Full Text Available This research followed 19 mature-aged distance students through their first semester of undergraduate study. The analysis of interviews and video diaries presented in this paper focuses on two key elements of emotional engagement: interest and belonging. Findings highlight the importance of interest triggered by personal preferences and experiences. Interest led to enjoyment, increased behavioural engagement with greater time and effort expended, and improved cognitive engagement in terms of depth and breadth of learning. In contrast, there was less evidence of the social side of emotional engagement, belonging. Participants felt little connection to the university, but connecting with fellow students through face-to-face courses and online forums was important for some to reduce their sense of isolation. However, distance study was not for all. The findings highlight the need for staff to consider emotional engagement when designing and delivering the curriculum and when interacting with students, particularly in the all-important first year.

    Exposure of cells to a wide variety of chemoprotective compounds confers resistance to a broad set of carcinogens. For a subset of the chemoprotective compounds, protection is generated by an increase in the abundance of protective enzymes, such as glutathione S-transferases (GSTs). In the present study, we developed a cell culture system that potently responds to phenolic antioxidants and found that antitumor prostaglandins (PGs) are potential inducers of GSTs. We screened primary hepatocytes and multiple cell lines for inducing GST activity upon incubation with the phenolic antioxidant (tert-butylhydroquinone) and found that rat liver epithelial RL34 cells most potently responded. Based on an extensive screening of diverse chemical agents on the induction of GST activity in RL34 cells, the J2 series of PGs, 15-deoxy-Delta(12,14)-prostaglandin J2 (15-deoxy-Delta(12,14)-PGJ2) in particular, were found to be potential inducers of GST. Enhanced gene expression of Class pi GST isozyme (GSTP1) by 15-deoxy-Delta(12,14)-PGJ2 was evident as a drastic elevation of the mRNA level. Hence, we examined the molecular mechanism underlying the 15-deoxy-Delta(12, 14)-PGJ2-induced GSTP1 gene expression. From functional analysis of various deletion mutant genes, we found that the 15-deoxy-Delta(12, 14)-PGJ2 reponse element was localized in a region containing a GSTP1 enhancer I (GPEI) that consists of two imperfect phorbol 12-O-tetradecanoylphorbol-13-acetate response elements. When the GPEI was combined with the minimum GSTP1 promoter, the element indeed showed an enhancer activity in response to 15-deoxy-Delta(12, 14)-PGJ2. Point mutations of either of the two imperfect 12-O-tetradecanoylphorbol-13-acetate response elements in GPEI completely abolished the enhancer activity. Gel mobility shift assays demonstrated that 15-deoxy-Delta(12,14)-PGJ2 specifically stimulated the binding of nuclear proteins including the transcription factor c-Jun, but not Nrf2, to GPEI.

  1. 15-Deoxy-Δ12,14-prostaglandin J2 inhibits macrophage colonization by Salmonella enterica serovar Typhimurium.

    Directory of Open Access Journals (Sweden)

    Michelle M C Buckner

    Full Text Available 15-deoxy-Δ(12,14-prostaglandin J2 (15d-PGJ2 is an anti-inflammatory downstream product of the cyclooxygenase enzymes. It has been implicated to play a protective role in a variety of inflammatory mediated diseases, including rheumatoid arthritis, neural damage, and myocardial infarctions. Here we show that 15d-PGJ2 also plays a role in Salmonella infection. Salmonella enterica Typhimurium is a Gram-negative facultative intracellular pathogen that is able to survive and replicate inside phagocytic immune cells, allowing for bacterial dissemination to systemic sites. Salmonella species cause a wide range of morbidity and mortality due to gastroenteritis and typhoid fever. Previously we have shown that in mouse models of typhoid fever, Salmonella infection causes a major perturbation in the prostaglandin pathway. Specifically, we saw that 15d-PGJ2 production was significantly increased in both liver and feces. In this work we show that 15d-PGJ2 production is also significantly increased in macrophages infected with Salmonella. Furthermore, we show that the addition of 15d-PGJ2 to Salmonella infected RAW264.7, J774, and bone marrow derived macrophages is sufficient to significantly reduce bacterial colonization. We also show evidence that 15d-PGJ2 is reducing bacterial uptake by macrophages. 15d-PGJ2 reduces the inflammatory response of these infected macrophages, as evidenced by a reduction in the production of cytokines and reactive nitrogen species. The inflammatory response of the macrophage is important for full Salmonella virulence, as it can give the bacteria cues for virulence. The reduction in bacterial colonization is independent of the expression of Salmonella virulence genes SPI1 and SPI2, and is independent of the 15d-PGJ2 ligand PPAR-γ. 15d-PGJ2 also causes an increase in ERK1/2 phosphorylation in infected macrophages. In conclusion, we show here that 15d-PGJ2 mediates the outcome of bacterial infection, a previously unidentified

    Students enter introductory astronomy classes with ideas about the universe that are often misaligned with accepted scientific beliefs. In this presentation we will describe the results from a multi-semester study of urban minority students’ ideas in an introductory astronomy course. We use in-depth student interviews, homework assignments, lab responses, and exams to identify pre-instructional ideas. We also examine the resilience of alternate conceptions to modification through instruction. In this presentation we focus on students’ ideas with regards to the Big Bang, the age of the Universe, and the expansion of the Universe over time. We find that a significant fraction of students enter our astronomy courses with alternate conceptions, including that the Big Bang refers to an explosion from a small, single point in space, that there is no evidence for the Big Bang, that there is a center to our Universe, that the Universe expands into pre-existing matter, and that the Universe has either a much smaller or much larger age than its accepted age. Some of these alternate conceptions are relatively easy to overcome through active learning (for example, whether there is a center to the Universe), while others are more resistant to change (for example, whether the Universe expands into pre-existing matter). Also see our presentations on student ideas of structure and distances (Camarillo et al.) as well as the overview of our methodology (Coble et al.).

    With the aging of the population comes a greater need for geriatric and gerontology teaching. However, there is currently a dearth of investigations on the impact of different educational methodologies for teaching in this area early in medical courses. The present study aims to determine the impact of two educational strategies on the topic "Geriatrics and Gerontology" ("experiencing aging" and "myths of aging") as compared to a control group (no intervention) on the attitudes, empathy and knowledge of first year medical students. An intervention-based study in education was conducted at the beginning of the first year of a medical course. Students submitted to educational strategies were compared against students with no intervention. The two strategies were: "Experiencing Aging" - also known as the "aging game" (simulation of the disabilities and physiological changes of aging), and "Myths of Aging" - a knowledge discussion based on a "quiz show", questioning common myths about aging. All students were assessed on their attitudes towards older persons (Maxwell-Sullivan, UCLA attitudes), empathy (Maxwell-Sullivan), knowledge on facts and positive view about aging (Palmore), and cognitive knowledge. Data were analysed using Student's t, Chi-squared or ANOVA tests. A total of 230 students were assessed. The "experiencing aging" intervention was associated with improvement in empathy but worsening of attitude. The "myths of aging" intervention was associated with an improved attitude overall and positive view about aging but with no change in empathy towards older persons. Educational strategies can influence the attitudes and empathy of students, leading to different outcomes. These data highlight the importance of assessing the outcomes of educational strategies in medical teaching to ascertain in what manner (how), situations (when) and settings (where) these activities should be introduced.

    The aim of this study was to evaluate sleep habits of nurses, medical students, and physicians and to explore whether they are influenced by age, sex, shift work, and caffeine consumption. The questionnaire was derived from the MEDSleep Survey. A total of 453 respondents were surveyed: second-year medical students (130); physicians at the postgraduate study program (68); specialists (162); nurses (93). Results of our study indicate that hours of sleep needed for feeling rested depends on age and gender. Younger respondents and women in the study need longer sleep to feel rested (7.5 hours and more) than older ones and males who need less than 7.5 hours of sleep. Among medical professionals a need for sleep differs related to work demands and work schedule. Nurses need more sleep than physicians (chi2 = 38.57, p trouble staying awake while listening to lectures or learning (chi2 = 9.37, p = 0.009), and while driving a car (chi2 = 14.56, p = 0.001).

A statistically significant relationship was found between the number of assertive behaviors occurring while listening to fast tempo music and grades and between difference scores and grades. Difference scores were obtained by subtracting the number of assertive behaviors occurring while listening to fast tempo music from those while listening to slow tempo music. Discriminant function analysis showed the number of assertive behaviors when listening to fast tempo music and difference scores were predictive of membership by grade. The higher the more assertive behaviors were emitted when listening to fast tempo music.

    A new generation of optical networking services and technologies is rapidly changing the world of communications. National and international networks are implementing optical services to supplement traditional packet routed services. On September 12-14, 2005, the Optical Network Testbeds Workshop 2 (ONT2), an invitation-only forum hosted by the NASA Research and Engineering Network (NREN) and co-sponsored by the Department of Energy (DOE), was held at NASA Ames Research Center in Mountain View, California. The aim of ONT2 was to help the Federal Large Scale Networking Coordination Group (LSN) and its Joint Engineering Team (JET) to coordinate testbed and network roadmaps describing agency and partner organization views and activities for moving toward next generation communication services based on leading edge optical networks in the 3-5 year time frame. ONT2 was conceived and organized as a sequel to the first Optical Network Testbeds Workshop (ONT1, August 2004, www.nren.nasa.gov/workshop7). ONT1 resulted in a series of recommendations to LSN. ONT2 was designed to move beyond recommendations to agree on a series of “actionable objectives” that would proactively help federal and partner optical network testbeds and advanced research and education (R&E) networks to begin incorporating technologies and services representing the next generation of advanced optical networks in the next 1-3 years. Participants in ONT2 included representatives from innovative prototype networks (Panel A), basic optical network research testbeds (Panel B), and production R&D networks (Panels C and D), including “JETnets,” selected regional optical networks (RONs), international R&D networks, commercial network technology and service providers (Panel F), and senior engineering and R&D managers from LSN agencies and partner organizations. The overall goal of ONT2 was to identify and coordinate short and medium term activities and milestones for researching, developing, identifying

    Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010-11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45 ± 1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (pObese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

    NASA participates in a wide variety of educational activities including competitive events. There are competitive events sponsored by NASA and student teams which are mentored by NASA centers. This participation by NASA in public forums serves to bring the excitement of aerospace science to students and educators. A new competition for highschool-aged student teams involving projects in microgravity has completed two pilot years and will have national eligibility for teams during the 2002-2003 school year. A team participating in the Dropping In a Microgravity Environment will research the field of microgravity, develop a hypothesis, and prepare a proposal for an experiment to be conducted in a microgravity drop tower facility. A team of NASA scientists and engineers will select the top proposals and those teams will then design and build their experiment apparatus. When the experiment apparatus are completed, team representatives will visit NASA Glenn in Cleveland, Ohio for operation of their facility and participate in workshops and center tours. Presented in this paper will be a description of DIME, an overview of the planning and execution of such a program, results from the first two pilot years, and a status of the first national competition.

    Approximately 50% of cats admitted to Australian shelters are kittens, and 26% of dogs are puppies, and, particularly for cats, euthanasia rates are often high. Cats can be pregnant by 4 months of age, yet the traditional desexing age is 5-6 months, and studies in Australasia and Nth America reveal that only a minority of veterinarians routinely perform early age desexing (EAD) of cats or dogs, suggesting they are not graduating with these skills. This study aimed to describe the attitudes of veterinary teaching staff in Australian and New Zealand universities towards EAD, and to determine if these changed from 2008 to 2015. It also aimed to identify students' practical exposure to EAD. Most (64%) of the 25 participants in 2015 did not advocate EAD in their teaching and, in their personal opinion, only 32% advocated it for cats. Concerns related to EAD cited by staff included anesthetic risk, orthopedic problems, hypoglycemia, and, in female dogs, urinary incontinence. Those who advocated EAD cited benefits of population control, ease of surgery and behavioral benefits. Only three of the eight universities provided a majority of students with an opportunity to gain exposure to EAD procedures before graduation, and in two of these, most students had an opportunity to perform EAD. In conclusion, most veterinary students in Australia and New Zealand are not graduating with the knowledge or skills to perform EAD, and have little opportunity while at university to gain practical exposure. Welfare agencies could partner with universities to enable students to experience EAD.

    This cross-sectional study investigated self-esteem in relation to age, gender, ethnicity, and risk behaviors among a sample of nonmainstream students. Participants were 149 students in the 6th to 12th grades from two nonmainstream schools (one charter and one alternative school). Self-esteem and youth risk behaviors were determined by using a modified version of the Rosenberg Self-Esteem Scale (Rosenberg, 1965) and the National Alternative High School Youth Risk Behavior Survey (Grunbaum et al., 1999), respectively. Results indicated that nonmainstream students with high self-esteem were more likely to engage in their first sexual experience and to begin marijuana use later in life. African American students reported having their first sexual experience at an older age, but having more sexual partners than did Latino students. The implications of these findings are discussed.

Email was also the most frequently cited preferred eHealth delivery platform, with 86% (43/50) of students selecting it. Facebook was preferred by the second greatest proportion of students (40%, 20/50). Most college freshmen have concerns about an array of weight gain prevention topics and are generally open to the possibility of receiving eHealth interventions designed to address their concerns, preferably via email compared with popular social media platforms. These preliminary findings offer a foundation to build upon when it comes to future descriptive investigations focused on behavioral weight gain prevention among college freshmen in the digital age. ©Courtney M Monroe, Gabrielle Turner-McGrievy, Chelsea A Larsen, Karen Magradey, Heather M Brandt, Sara Wilcox, Beth Sundstrom, Delia Smith West.

    2017-11-01

    The purpose of this systematic review was to examine influences affecting sleep behavior in traditional-age college students and to advocate for improved sleep behavior assessments. A literature search of CINAHL, MEDLINE, and PubMed databases was performed using the search terms "college students" and "sleep" in the title that were published in English from 1978 to 2016. The circadian clock is reset in traditional-age college students leading to delayed sleep times. Newly realized autonomy and increased use of technology also prevent traditional-age college students from obtaining sufficient sleep. Insufficient sleep experienced by these students has been linked to insulin resistance, hypertension, diabetes, weight gain, and stress. Sleep insufficiency increases the risk for pedestrian, motor vehicle, and domestic and occupational injuries. Insufficient sleep may result in poor academic performance influencing subsequent health outcomes. Evidence supports the need for nurse practitioners and other healthcare providers to incorporate systematic sleep behavior assessments to improve health outcomes among traditional-age college students. ©2017 American Association of Nurse Practitioners.

    The hypothesis that exposure to ionizing radiation accelerates the aging process has been actively investigated at ABCC-RERF since 1958, when longitudinal cohort studies of the Adult Health Study (AHS) and the Life Span Study (LSS) were initiated. In their 1975 overall review of aging studies related to the atomic bomb (A-bomb) survivors, Finch and Beebe concluded that while most studies had shown no correlation between aging and radiation exposure, they had not involved the large numbers of subjects required to provide strong evidence for or against the hypothesis. Extending LSS mortality data up to 1978 did not alter the earlier conclusion that any observed life-shortening was associated primarily with cancer induction rather than with any nonspecific cause. The results of aging studies conducted during the intervening 15 years using data from the same populations are reviewed in the present paper. Using clinical, epidemiological, and laboratory techniques, a broad spectrum of aging parameters have been studied, such as postmortem morphological changes, tests of functional capacity, physical tests and measurements, laboratory tests, tissue changes, and morbidity. With respect to the aging process, the overall results have not been consistent and are generally thought to show no relation to radiation exposure. Although some preliminary results suggest a possible radiation-induced increase in atherosclerotic diseases and acceleration of aging in the T-cell-related immune system, further study is necessary to confirm these findings. In the future, applying the latest gerontological study techniques to data collected from subjects exposed 45 years ago to A-bomb radiation at relatively young ages will present a new body of data relevant to the study of late radiation effects.

    The hypothesis that ionizing radiation accelerates natural aging has been under investigation at the Atomic Bomb Casualty Commission since 1959. Postmortem observations of morphologic and chemical changes, tests of functional capacity, physical tests and measurements, clinical laboratory tests, tissue changes, morbidity, and mortality have all been examined by ABCC investigators interested in this hypothesis. These studies have been beset with conceptual difficulties centered on the definition and measurement of aging. An empirical approach early led to the calculation of an index of physiologic age as a linear combination of age-related tests of various organ systems. Most studies have been negative but have not involved the large numbers that might be required to provide strong evidence for or against the hypothesis. Mortality, however, has been examined on the basis of a large sample and over the period 1950-1972 had provided no support for the hypothesis of radiation-accelerated aging. Ionizing radiation dose, of course shorten human life, but its life-shortening effect appears to be the result of specific radiation-induced disease, especially neoplasms. The hypothesis is now much less attractive than it was 10-20 years ago but still has some value in stimulating research on aging. The experience of the A-bomb survivors provides an unusual opportunity for a definitive test of the hypothesis. (auth.)

    Reasons for referring school-age children to occupational therapy mainly relate to handwriting problems. However, there are no validated tools or reference values for assessing handwriting in francophone children in Canada. This study aimed to adapt and validate the writing tasks described in an English Canadian handwriting assessment protocol and to develop reference values for handwriting speed for francophone children. Three writing tasks from the Handwriting Assessment Protocol-2nd Edition (near-point and far-point copying and dictation) were adapted for Québec French children and administered to 141 Grade 1 ( n = 73) and Grade 2 ( n = 68) students. Reference values for handwriting speed were obtained for near point and far point copying tasks. This adapted protocol and these reference values for speed will improve occupational therapy handwriting assessments for the target population.

    The population of mature age students entering university nursing programs has steadily increased in both Australia and worldwide. The objective of the literature review was to explore how mature age students perform academically and to analyse the factors associated with their academic performance in nursing programs. A literature search was conducted in the following databases: CINAHL, ProQuest, Medline, Cochrane, Mosby's Index, Joanna Briggs Institute (JBI), and Scopus. Twenty-six (26) research papers published between 2000 and 2014 have met the selection criteria of this review. The key themes identified include; 1) ambiguity in definition of mature age and academic success, 2) age and academic success, 3) intrinsic factors (life experiences, emotional intelligence, and motivation and volition), and 4) extrinsic factors (peer, academic and family support; and learning style, components of the modules and mode of delivery). Current literature provides evidence that mature age nursing students perform at a higher level within the methodological issues discussed in this paper. Future research is warranted to advance the understanding of the complex relationship between extrinsic and intrinsic factors of mature age students and their academic success in higher education. Nursing educators will benefit from novel evidence, ideas and opportunities to explore and implement in nursing education.

    Beliefs in the paranormal were rated stronger in younger as compared to elderly adults by Emmons and Sobal in 1981, and sex correlates of paranormal beliefs appeared to be stronger in women than in men by Irwin in 1994. This research studied possible linkages between age and sex with a comparative analysis between results of Vitulli and Luper's 1998 survey among undergraduate students and data from elderly men (M = 72 yr., SD = 9.2, n = 21) and women (M = 69.3 yr., SD = 7.7, n = 55). Crawford and Christensen's 1995 12-item Extrasensory Perception Survey was administered to elderly persons living in apartment complexes and private homes, participating in activities in a recreation center, or attending a continuing-education seminar. A 2 x 2 multivariate analysis of variance from responses on the 12-item survey showed that undergraduate men and elderly women had the highest ratings on paranormal beliefs. The self-selecting characteristics of a segment of the elderly sample led to a post hoc univariate analysis of variance by partitioning that sample into those who were attending a continuing-education seminar versus all other elderly persons. Summated ratings (total scores) for this survey showed main effects for these subsamples and for sex. Sex and age differences were discussed in the context of the hypothesis of social marginality.

    Emotional intelligence (EI) is an important personality trait in healthcare professionals and students. This study aims to identify gender, age or culture differences in trait EI scores between student radiographers across four countries. The short form of the trait EI questionnaire (TEIQue-SF) was used to collect data from first year radiography students in Australia, Hong Kong, Ireland and the United Kingdom. Global EI and Sociability scores of the first year radiography students were in keeping with published norm data in terms of gender differences, however, Self-Control and Emotionality scores did not follow the gender-based norms. Statistically significant differences in Global EI (p = 0.02), Wellbeing (p = 0.002) and Sociability (p = 0.003) were found with Western versus Asian cultures being a key factor. This study highlights a number of EI findings of importance to health-related professional programmes and the potential impact of cultural background on this key personality trait. - Highlights: • Emotional intelligence is a key trait for healthcare professionals and healthcare students. • Gender, age and culture impact on trait emotional intelligence scores of radiography students. • Differences in trait emotional intelligence scores exist between Western and Asian radiography students.

    The aim of this qualitative study was to measure the effect of a specifically designed orientation re-enactment DVD used to facilitate dental hygiene students transition from the classroom to a Residential Aged Care Facility (RACF) service-learning placement with less personal anxiety and more confidence in their role during the placement. Final year students (n = 47) were randomly allocated to one of 17 RACFs on the NSW, Central Coast, Australia. All students were then randomly allocated to a two-group study with the active group assigned to view the DVD prior to their placement. Students who viewed the DVD were asked not to discuss the content with students who were assigned to the control group. Post-placement focus groups were organized, recorded and transcribed verbatim. Data were collated, analysed and unitized into emergent themes. Representative quotes are presented in the results. The study was informed by 4 years of previous quantitative and qualitative process evaluation of the RACF programme. Focus group discussions identified that those students who had seen the DVD reported a shorter timeframe to successfully transition from the classroom to the RACF and stated that the DVD provided them with a realistic expectation of the RACF environment and their role in the placement experience. The orientation DVD reduced student anxiety and improved student confidence in their role during the placement by providing a realistic orientation of the RACF environment. © 2015 John Wiley & Sons A/S.

Only three of the eight universities provided a majority of students with an opportunity to gain exposure to EAD procedures before graduation, and in two of these, most students had an opportunity to perform EAD. In conclusion, most veterinary students in Australia and New Zealand are not graduating with the knowledge or skills to perform EAD, and have little opportunity while at university to gain practical exposure. Welfare agencies could partner with universities to enable students to experience EAD.

    Full Text Available The characteristics of Information and Communication Technologies (ICT and their implementation at the global level have led to significant changes in different areas, especially institutional ones. This article presents the results of a research study whose purpose was to learn the level of digital competence of university students of education and to verify whether the variables of gender and age have any influence on it. A quantitative methodology was used, with a non-experimental, descriptive and inferential method, and the digital questionnaire was employed as an instrument for collecting information on the dimensions of knowledge and management of ICTs as well as attitudes towards them. The data were analysed based on a comparison of means, using non-parametric tests. The results show that the sample studied self-evaluated negatively their knowledge of ICT concepts, considered positive their management of devices, tools and services, and showed a very positive attitude toward technology. Regarding the variables studied, significant differences were found in favour of men in relation to knowledge and management, and in favour of older subjects with regard to attitude.

    Full Text Available Dental enamel is the end product of amelogenesis, which can be considered to take place in"nthree interrelated phases. When this complex sequence of cytological and physicochemica! events"ndisrupted by genetic or environmental factors, the function of the ameloblasts may be disrupted"npermanently or temporarily. The result shows qualitative and quantitative defects that may range from a"ncomplete absence of enamel or a slight discoloration. The aim of this study was to determine the"nprevalence of enamel defects by DDE index in a randomly selection group of 1637 students age 7-12"nyears old in Isfahan (0.2-0.3 PPMF". Enamel defects were present on one or more teeth in 27% of the"ncases. The most common affected tooth was the central maxillary and then first molar of maxilla. The"nmost common affected surfaces were buccal. Hypoplastic defects were found in first molar; however"npremolar and canine were affected by diffuse white lines opacity.

    Although the relationships between economic conditions and biological variables over the past two centuries in Poland are reasonably well-documented, the influence of economic and political disruptions, including nutritional privation, during the years immediately before, during and shortly after World War II (WWII) has received less attention. This paper considers the association between age at menarche and body size of university students born before, during and after WWII and father's level of education, a commonly used indicator of family economic status in Poland. Subjects were 518 university students surveyed between 1955 and 1972, birth years 1931 through 1951. The sample was divided into three birth cohorts: before (n=237), during (n=247) and after (n=34) WWII. Age at menarche was compared among birth cohorts, and by weight status and father's level of education. Age at menarche increased slightly but significantly among women born during WWII (14.4 yrs) compared to those born before (14.2 yrs) and after (13.9 yrs) the war. Controlling for year of birth and age of the student, age at menarche was significantly earlier in overweight (13.42±0.35 yrs) than in normal weight (14.33±0.06 yrs) and thin (14.54±0.21 yrs) women. Adjusted mean ages at menarche in small samples of overweight women did not differ by father's level of education, and were earlier than corresponding ages of thin and normal weight women. Adjusted mean ages at menarche did not differ between thin and normal weight women with fathers having primary or no education, but were slightly later in thin than in normal weight women with fathers having a vocational, secondary or higher education. Although age at menarche was associated with father's level of education, young adult weight status was a somewhat more important correlate. Copyright © 2017 Elsevier B.V. All rights reserved.

    Nutrition plays an important role in the elderly stage of life. A proper proportion of the individual nutritional ingredients in a diet may positively impact the ageing body. This positive influence consists in slowing down the undesired and unfavourable physiological alterations leading inevitably to the general weakness of the body. The aim of the paper was to perform a qualitative analysis with the Starzyńska scoring system for diets, the daily food rations (DFR), among students of the University of the Third Age at the Koszalin University of Technology (Poland). The studied materials consisted of the 7-day current records made by 79 students (16 males and 63 females) of the University of the Third Age at the Koszalin University of Technology and the measurements of body weight, height and waistline. The records were qualitatively evaluated with Starzyńska's test. It was found that approximately half of the students were overweight or obese. The majority consumed the recommended number of meals. About 44% of the students consumed animal protein with all meals. Milk and cheese were ingested daily with at least two meals by approximately 11% of the students. Fruit and vegetables are eaten on a daily basis by about 60% of the students. Almost 40% ate wholegrain bread, groats, and dried legumes. The statistical analysis of the means for the points of individual indicators did not reveal any statistically significant difference between women and men (p>0.05). Approximately ¾ of the evaluated diets were inaccurately formulated and required radical modification. The low frequency of animal protein, milk and cheese, wholegrain bread, groats and dried legume consumption may result in deficiencies in certain nutrients. Nutritional education is recommended, focusing on the correct way to formulate meals. The recorded level of overweight and obesity in the students indicates a need for a quantitative assessment of consumption considering, among others, the energy input

    To examine whether television viewing, computer game playing or book reading during meals predicts meal skipping with the aim of watching television, playing computer games or reading books (media meal skipping). A cross-sectional study was conducted using a standardized self-administered questionnaire. Analyses were controlled for age, gender and BMI. Data were obtained from a random sample of adolescents in Flanders, Belgium. Seven hundred and ten participants aged 12, 14 and 16 years. Of the participants, 11.8 % skipped meals to watch television, 10.5 % skipped meals to play computer games and 8.2 % skipped meals to read books. Compared with those who did not use these media during meals, the risk of skipping meals in order to watch television was significantly higher for those children who watched television during meals (2.9 times higher in those who watched television during at least one meal a day). The risk of skipping meals for computer game playing was 9.5 times higher in those who played computer games weekly or more while eating, and the risk of meal skipping in order to read books was 22.9 times higher in those who read books during meals less than weekly. The more meals the respondents ate with the entire family, the less likely they were to skip meals to watch television. The use of media during meals predicts meal skipping for using that same medium. Family meals appear to be inversely related to meal skipping for television viewing.

    Educational graduates should have good competencies to compete in the 21st century. Integrated learning is a good way to develop competence of students in this century. Besides that, literacy skills are very important for students to get success in their learning and daily life. For this reason, integrated science learning and literacy skills are important in 2013 curriculum. However, integrated science learning and integration of literacy in learning can’t be implemented well. Solution of this problem is to develop adaptive contextual learning model by integrating digital age literacy. The purpose of the research is to determine the effectiveness of adaptive contextual learning model to improve competence of grade VIII students in junior high school. This research is a part of the research and development or R&D. Research design which used in limited field testing was before and after treatment. The research instruments consist of three parts namely test sheet of learning outcome for assessing knowledge competence, observation sheet for assessing attitudes, and performance sheet for assessing skills of students. Data of student’s competence were analyzed by three kinds of analysis, namely descriptive statistics, normality test and homogeneity test, and paired comparison test. From the data analysis result, it can be stated that the implementation of adaptive contextual learning model of integrated science by integrating digital age literacy is effective to improve the knowledge, attitude, and literacy skills competences of grade VIII students in junior high school at 95% confidence level.

    More and more, interest in the way data is displayed on screen has increased, especially with the increase in the number of people using e-text for learning purposes. So, this requires more focus on factors that affect screen legibility. Text display factors, such as font size, line length and font type, have an impact on reading online. Two font types [Arabic Traditional and Simplified Arabic] in four different sizes [10, 14, 16 and 18] are measured using Arabic text. On-line processes were measured using reading-aloud technique. Accuracy of reading was also measured by the average of errors that students made when reading the text, while reading speed was tested by the time it took students to read the text. However, results indicated that Arabic text in font size 10 is not readable to students aged 10 to 12. On the other hand, font sizes sixteen and eighteen are more readable than any smaller-sized font, the averages of error size 18 improve in all font types, while age has a significant impact on reading speed. Simplified Arabic font is reported as readable to students aged 10-12, especially in sizes 14 and 18.

    Tryptophan can be metabolized via 5-hydroxytryptamine=serotonin to melatonin by a series of 4 enzymes in pineal body. Lack of serotonin in body fluid in the brain during daytime can lead to several psychiatric disorders, while shortage of plasma-melatonin at night can be related to sleep disorders. The Morning-Evening (M-E) questionnaire and the original questionnaire including questions on sleep habits, mental symptoms, and contents of meals were administered to 1055 infants aged 0-6 yrs, 751 students attending an elementary school, and 473 students attending junior high school in Kochi City (33 degrees N). The index of tryptophan taken at breakfast (Trp-Index) was calculated as tryptophan amount per one meal based on the tryptophan included in each 100 g of the foods and a standard amount of food per one meal. A significant positive-correlation between M-E scores and Trp-Index was not shown by relatively older students, aged 9-15 yrs (Pearson's test, r=0.044-0.123, p=0.071-0.505), whereas a significant positive correlation was shown by infants and young elementary school students aged 0-8 yrs (r=0.180, 0.258, phigh quality of sleep, and indirectly good mental health, presumably, through the metabolism of tryptophan to serotonin in daytime and further to melatonin at night.

    To describe whether an action research approach can be used to build capacity of residential aged care facility staff to support undergraduate nursing students' clinical placements in residential aged care facilities, using development of an orientation programme as an exemplar. Aged care facilities are unpopular sites for nursing students' clinical placements. A contributing factor is the limited capacity of staff to provide students with a positive placement experience. Strategies to build mentor capability to shape student placements and support learning and teaching are critical if nursing students are to have positive placements that attract them to aged care after graduation, an imperative given the increasing care needs of the ageing population worldwide. Action research approach employing mixed-methods data collection (primarily qualitative with a quantitative component). Aged care facility staff (n = 32) formed a mentor group at each of two Tasmanian facilities and met regularly to support undergraduate nursing students (n = 40) during placements. Group members planned, enacted, reviewed and reflected on orientation procedures to welcome students, familiarise them with the facility and prepare them for their placement. Data comprised transcripts from these and parallel student meetings, and orientation data from student questionnaires from two successive placement periods (2011/2012). Problems were identified in the orientation processes for the initial student placements. Mentors implemented a revised orientation programme. Evaluation demonstrated improved programme outcomes for students regarding knowledge of facility operations, their responsibilities and emergency procedures. Action research provides an effective approach to engage aged care facility staff to build their capacity to support clinical placements. Building capacity in the aged care workforce is vital to provide appropriate care for residents with increasing care needs. © 2016 John

    2014-09-29

    This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=-0.19; pbody mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016) and lower levels of self-esteem (r=-0.17, pbody dissatisfaction (F=4.79; p=0.030; η(2)=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η(2)=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the non-practitioners group.

It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the nonpractitioners group.

    Older adults living in residential aged care facilities (RACFs) often experience limited opportunities for social connection despite close proximity to peers, which has implications for mental health and quality of life (QoL). The introduction of large-scale undergraduate health student placements in RACFs may enhance opportunities for meaningful engagement through social connection, although this remains unexplored. This research explores whether interpersonal encounters between health students and RACF residents influence residents' opportunities for social connection and QoL. A mixed methods design was employed which included questionnaire data from residents, and qualitative interview data from residents, family members and RACF staff. Data were collected during and after student placements to allow for an in-depth exploration of residents, family members and staff perspectives. Forty-three participants (28 residents, 10 staff and five family members) were recruited during 2014. Overall, many residents had clinical levels of depression, mild cognitive impairment and multiple morbidities, however reported moderate-to-good QoL. Thematic analysis was undertaken on interview transcripts, and three themes emerged: (i) social isolation and loneliness fostered by residents' age-related conditions, (ii) students expand socially supportive connections beyond the RACF and (iii) meaning making by sharing health experiences, which was found to help renegotiate older adults' pervasive narrative of vulnerability. Supported and structured health student placements in RACFs enable older adults to participate in meaningful encounters with younger people. These encounters focus on sharing health experiences and address long-standing issues of isolation and loneliness by providing opportunities for social connection. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Full Text Available It has been reported that bone marrow-derived mesenchymal stem cells (BMSCs have capacity to migrate to the damaged liver and contribute to fibrogenesis in chronic liver diseases. 15-Deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2, an endogenous ligand for peroxisome proliferator-activated receptor gamma (PPARγ, is considered a new inhibitor of cell migration. However, the actions of 15d-PGJ2 on BMSC migration remain unknown. In this study, we investigated the effects of 15d-PGJ2 on the migration of BMSCs using a mouse model of chronic liver fibrosis and primary mouse BMSCs. Our results demonstrated that in vivo, 15d-PGJ2 administration inhibited the homing of BMSCs to injured liver by flow cytometric analysis and, in vitro, 15d-PGJ2 suppressed primary BMSC migration in a dose-dependent manner determined by Boyden chamber assay. Furthermore, the repressive effect of 15d-PGJ2 was blocked by reactive oxygen species (ROS inhibitor, but not PPARγ antagonist, and action of 15d-PGJ2 was not reproduced by PPARγ synthetic ligands. In addition, 15d-PGJ2 triggered a significant ROS production and cytoskeletal remodeling in BMSCs. In conclusion, our results suggest that 15d-PGJ2 plays a crucial role in homing of BMSCs to the injured liver dependent on ROS production, independently of PPARγ, which may represent a new strategy in the treatment of liver fibrosis.

    2013-10-01

    Full Text Available The paper describes the results of a study of functions of argumentation in solving conflicting situations of social interaction, with the participation of younger students (III and IV grade, middle school students (V and VII grade and high school students (X classes, 211 students overall. The starting point of the research was the idea that distress occurring in a contradictory situation, does not relieve externally, but requires a structural analysis of the situation and a decision from the subject. The hypothesis of the study was the assumption that the argument used by the subject in a situation, can have opposite functions: a real change in the situation or a formal removal of contradictions in order to reduce stress. The author notes that overcoming the contradictions is linked inevitably to the need to clarify the rules of interaction between the parties, and this in turn puts the subject under certain psychological risk (the risk of criticism, disapproval or punishment, the risk of loss of secondary benefits of ambiguous situation, etc. that impede productive action in a contradictory situation.

    Full Text Available

    Aim: The aim of this study was to find out at what age children start smoking, as well as their tobacco habits and risk perceptions according to the different school-age groups.

    Methods: A cross-sectional survey was carried out in 2007; it involved around 1700 students of the Catania province, in Southern Italy. The students filled in a structured tobacco questionnaire. They did it anonymously in the classrooms. Main outcome measures were initiation of smoking, smoking habits, number of cigarettes smoked per day and risk perception.

    Results: From the first year of the primary school to the last year of the high school the proportion of daily smokers increased from 0.0% to 11.8% for girls and from 0.8% to 12.7% for boys. For both genders the initiation of smoking habits occurred mainly at age 10 to 13. Finally, girls had a better risk perception.

    Conclusions: Studying young people’s tobacco habits over time gives an understanding of when preventive measures have to be implemented. In order to influence smoking attitudes, these preventive interventions must be put in place before children start experimenting tobacco.

    Full Text Available The article provides results of the research on eating behavior and diet peculiarities of students belonging to various age groups, who studied at secondary schools in the villages and district centers of Lviv Region. It was found that students of different age groups (grades have certain eating behavior peculiarities, though none of them corresponds to the model of balanced nutrition. In particular, students of 1-4 grades mainly consumed specially cooked food 4-5 times a day at home, did not always eat their entire serve, and often had snacks in between the main meals, eating vegetables/fruits, and bakery. Their behavior during food intake is agitated and unfocused. Eating behavior of secondary school students had the following peculiarities: the majority of students ate 3 times a day and were likely to ignore breakfasts, consumed food cooked for the whole family and did at home, did not always eat all of the offered serve. Instead, at schools they had frequent snacks consisting of vegetables/fruit, bakery, and sweets. With regard to seniors, their eating behavior had its own peculiarities. They were primarily related to active physiologic increase in body growth and weight, the need to spend the whole academic day at school, spend more time on homework, as well as help parents around the house. This research group had 9.7% of persons who had an adequate meal 6 times a day. However, the diet was unbalanced, since most meals where consumed in the afternoon, as well as during evening and night hours. We should also note, that students of 9-11 grades more often than other age groups in the research, ate at school canteens and public catering establishments, ate all of the food offered to them, were calm and attentive during food intake and had the largest number of snacks in between the main meals. What concerns their diet, it did not correspond to the characteristics of the balanced one, when it comes to consuming products required for the

    The undertaken research aimed at determining the frequency of deliberate self-injurious behaviour (D-SIB) among the students of secondary schools and also the analysis of the frequency of repeated Non-Suicidal Self-Injury (NSSI) occurrences in accordance with DSM-5 criteria in reference to the age and sex in the studied population. The data was collected via survey method according to the questionnaire prepared in compliance with the criteria DSM-5 and Self-Harm Inventory. The study included randomly selected students: 1193 boys and 1027 girls in Bialystok aged 12 and 19 (average age ± SD:16.8 ± 1.65). Statistical analysis of the data was carried out using the application Statistica 10.0 PL, StatSoft. These results indicate that D-SIB and NSSI affect both sexes. In the studied group 8.3 % of students engage in deliberate self-injurious behaviour. The percentage of NSSI was 4.8% (6.3% in the group of boys, 3.2 % among girls; p(Chi2)=0.01). Self-cutting was most common among 15-year-old pupils ((D-SIB:14.75%; NNSI:8.1%). The majority of respondents (82% of girls and 74% of boys) revealed that as a result of self-injury behaviour they experience relief. Conducting further research in the area of NSSI seems to be crucial due to chronicity and prevalence as well as the fact that numerous repeated self-injuries bringing relief or causing positive state of mind might indicate a mechanism similar to an addiction syndrome in adolescence.

    The success of university students depends on their ability to utilize time properly and completely. Students are required to learn to manage time so that they are able to apply the same degree of efficiency in the profession they choose after completing their education. This descriptive, cross-sectional study was conducted to determine nursing and midwifery students' time management skills in terms of their age, gender, and anxiety levels. The study population consisted of 1002 students, of which 584 students were selected for sampling. A Student Information Form, Time Management Inventory, and State-Trait Anxiety Inventory were used to collect data. Among the students, 89.9% were female, and the average age was 20.58 years (SD = 2.10). The average score of the Time Management Inventory was 87.79 (SD = 11.78), the mean score of the State Anxiety Inventory was 40.11 (SD = 10.84), and that of the Trait Anxiety Inventory was 43.95 (SD = 7.98). Nursing and midwifery students' time management skills are at mid-level point. Female students were able to manage time better than male students and the time management skills of the students decreased as the anxiety level increased. Copyright © 2012 Elsevier Ltd.

    The cyclopentenonic prostaglandin 15-deoxy-{Delta}{sup 12,14}-PG J{sub 2} (15d-PGJ{sub 2}) is a metabolite derived from PGD{sub 2}. Although 15d-PGJ{sub 2} has been demonstrated to be a potent ligand for peroxisome proliferator activated receptor {gamma} (PPAR{gamma}), the functions are not fully understood. In order to examine the effect of 15d-PGJ{sub 2} on histone acetyltransferases (HATs), several lines of cell including mouse embryonic fibroblast (MEF) cells were exposed to 15d-PGJ{sub 2}. Three types of HAT, p300, CREB-binding protein (CBP), and p300/CBP-associated factor (PCAF), selectively disappeared from the soluble fraction in time- and dose-dependent manners. Inversely, HATs in the insoluble fraction increased, suggesting their conformational changes. The decrease in the soluble form of HATs resulted in the attenuation of NF-{kappa}B-, p53-, and heat shock factor-dependent reporter gene expressions, implying that the insoluble HATs are inactive. The resultant insoluble PCAF and p300 seemed to be digested by proteasome, because proteasome inhibitors caused the accumulation of insoluble HATs. Taken together, these results indicate that 15d-PGJ{sub 2} attenuates some gene expressions that require HATs. This inhibitory action of 15d-PGJ{sub 2} on the function of HATs was independent of PPAR{gamma}, because PPAR{gamma} agonists could not mimick 15d-PGJ{sub 2} and PPAR{gamma} antagonists did not inhibit 15d-PGJ{sub 2}.

Characteristics of lung inflammation, airway hyper-reactivity (AHR, mucus exacerbation, and lung remodeling in sensitized A/J mice treated or not with 15d-PGJ2 were assessed. 15d-PGJ2 treatments were carried out systemically or topically given via subcutaneous injection or intranasal instillation, respectively. Analyses were carried out 24 h after the last allergen provocation. Irrespective of the route of administration, 15d-PGJ2 significantly inhibited the peribronchial accumulation of eosinophils and neutrophils, subepithelial fibrosis and also mucus exacerbation caused by either OVA or HDM challenge. The protective effect of 15d-PGJ2 occurred in parallel with inhibition of allergen-induced AHR and lung tissue production of pro-inflammatory cytokines, such as interleukin (IL-5, IL-13, IL-17, and TNF-α. Finally, 15d-PGJ2 was found effective in inhibiting NF-κB phosphorylation upon HDM challenge as measured by Western blotting. In conclusion, our findings suggest that 15d-PGJ2 can reduce crucial features of asthma, including AHR, lung inflammation, and remodeling in distinct murine models of the disease. These effects are associated with a decrease in lung tissue generation of pro-inflammatory cytokines by a mechanism related to downregulation of NF-κB phosphorylation.

    Proliferation of vascular smooth muscle cells (VSMCs) is induced by various mitogens through activation of extracellular signal-regulated protein kinase (ERK) pathway. We recently reported that peroxisome proliferator-activated receptor (PPAR)γ activators such as 15-deoxy-Δ 12,14 -prostaglandin J2 (15-d-PGJ2) and thiazolidinediones (TZDs) activated MEK/ERK pathway through phosphatidylinositol 3-kinase (PI3-K) and induced proliferation of VSMCs. However, the precise mechanisms of PPARγ activators-induced activation of PI3-K/ERK pathway have not been determined. We examined whether transactivation of growth factor receptor is involved in this process. Stimulation of VSMCs with 15-d-PGJ2 or TZDs for 15 min induced phosphorylation of ERK1/2 and Akt. 15-d-PGJ2- or TZDs-induced phosphorylation of ERK1/2 and Akt was inhibited by AG1478, an inhibitor of epidermal growth factor receptor (EGF-R) as well as AG1295, an inhibitor of platelet derived growth factor receptor (PDGF-R). 15-d-PGJ2-induced phosphorylation of both EGF-R and PDGF-R. GM6001, a matrix metalloproteinase inhibitor, and PP2, a Src family protein kinase inhibitor, suppressed 15-d-PGJ2- and TZDs-induced phosphorylation of EGF-R and PDGFβ-R as well as activation of ERK1/2 and Akt. PDGFβ-R was co-immunoprecipitated with EGF-R, regardless of the presence or absence of 15-d-PGJ2. These data suggest that 15-d-PGJ2 and TZDs activate PI3-K/ERK pathway through Src family kinase- and matrix metalloproteinase-dependent transactivation of EGF-R and PDGF-R. Both receptors seemed to associate constitutively. This novel signaling mechanisms may contribute to diverse biological functions of PPARγ activators

    Highlights: ► 15d-PGJ{sub 2} decreased IL-13 mRNA transcription and secretion in activated T cells. ► IL-13 inhibition by 15d-PGJ{sub 2} is independent of PPAR-γ. ► The nuclear factor-κB mediates the 15d-PGJ{sub 2}-dependent down regulation of IL-13. -- Abstract: Interleukin (IL)-13 is a cytokine produced by activated CD4{sup +} T cells that plays a critical role in promoting allergic responses and tumor cell growth. The 15-deoxy-Δ{sup 12,14}-prostaglandin J{sub 2} (15d-PGJ{sub 2}) is a natural ligand for the nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR-γ), a known regulator of anti-inflammatory activities. We determined the effects of 15d-PGJ{sub 2} on IL-13 expression in the Jurkat E6.1 T-cell line and in peripheral blood mononuclear cells. Semi-quantitative reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay revealed that treatment of activated T cells with 15d-PGJ{sub 2} significantly decreased IL-13 mRNA transcription and secretion, respectively. This inhibition by 15d-PGJ{sub 2} was independent of PPAR-γ since treatment with GW9662, an irreversible antagonist of the nuclear receptor, produced no effect. Our data also revealed the involvement of nuclear factor-κB in mediating 15d-PGJ{sub 2}-dependent down regulation of IL-13 expression. Collectively, these results demonstrate the potential of 15d-PGJ{sub 2} in attenuating expression and production of IL-13 in activated T cells.

  8. 15-Deoxy-Δ12,14-Prostaglandin J2 regulates leukemia inhibitory factor signaling through JAK-STAT pathway in mouse embryonic stem cells

    Embryonic stem (ES) cells are genetically normal, pluripotent cells, capable of self-renewal and differentiation into all cell lineages. While leukemia inhibitory factor (LIF) maintains pluripotency in mouse ES cells, retinoic acid and other nuclear hormones induce neuro-glial differentiation in mouse and human ES cells in culture. Peroxisome-proliferator-activated receptors (PPARs) are ligand-dependent nuclear receptor transcription factors that regulate cell growth and differentiation in many cell types. However, the role of PPARs in the regulation of ES cell growth and differentiation is not known. In this study, we show that LIF induces proliferation and self-renewal of mouse D3-ES cells in culture. However, treatment with 15-Deoxy-Δ 12,14 -Prostaglandin J 2 (15d-PGJ2), a natural ligand for PPARγ, or all-trans retinoic acid (ATRA) results in a dose-dependent decrease in proliferation and self-renewal in D3-ES cells. Immunoprecipitation and Western blot analyses showed that LIF induces tyrosine phosphorylation of JAK1, TYK2 and STAT3 in 30 min and treatment with 15d-PGJ2 or ATRA results in a dose-dependent decrease in LIF-induced phosphorylation of JAK1 and STAT3 in D3-ES cells. However, treatment of D3-ES cells with Ciglitazone or 15d-PGJ2 for 48 h in culture resulted in a dose-dependent increase in PPARγ protein expression. These results suggest that PPARγ agonists regulate LIF signaling through JAK-STAT pathway leading to growth and self-renewal of ES cells

    Concerns around organisational learning culture limit nursing student placements in aged care settings to first year experiences. Determine the impact of an extended staff capacity building program on students' experiences of the organisational learning culture in the aged care setting. Pre and post-test design. A convenience sample of first, second and third year Bachelor of Nursing students attending placements at three residential aged care facilities completed the Clinical Learning Organisational Culture Survey. Responses between the group that attended placement before the program (n = 17/44; RR 38%) and the group that attended following the program (n = 33/72; RR 45%) were compared. Improvements were noted in the areas of recognition, accomplishment, and influence, with decreases in dissatisfaction. Organisational investment in building staff capacity can produce a positive learning culture. The aged care sector offers a rich learning experience for students when staff capacity to support learning is developed.

    The assessment of quality of life (QoL) among elderly people is of great importance when preparing health care programmes for this social group. Many researchers indicate that poor health is less frequently observed in senior citizens who display levels of physical activity (PA) prescribed by WHO. The aim of the study was to investigate the relationship between the level of PA among students of the University of the Third Age (U3A) and their self-assessment concerning their QoL. The research sample consisted of 131 students from three U3A in West Pomeranian Voivodeship in Poland. PA was assessed with the aid of a short Polish version of the International Physical Activity Questionnaire (IPAQ). The assessment of QoL was conducted with the use of a Polish version of the WHO Quality of Life--BREF instrument (WHOQOL-BREF). The present study has shown that highly active U3A students declare high QoL in the psychological and social domains more often than other respondents. The level of PA recommended by WHO has a positive impact on the perceived QoL. Possible differences are visible mostly in the assessment of different domains of life in relation to the presented levels of PA. Copyright© by the National Institute of Public Health, Prague 2015.

    2017-06-01

    This research aimed at identifying student profiles of perceptions by means of a clustering method using a validated questionnaire. These profiles describe students' attraction to science and technology (S&T) studies and careers as a variable driven by school S&T self-concept and interest in school S&T. In addition to three rather predictable student profiles (confident enthusiast, average ambitious, and pessimistic dropout), the fourth fairly well-populated profile called confident indifferent was produced. Our second and third research questions allowed us to describe each profile in terms of the instructional methods to which their population was exposed (including the degree to which they were actively involved) and the instructional methods to which they would like more exposure. An analysis of the evolution of the profiles' population over time is also presented. The results suggest that pedagogical variety and active involvement in the decision to pursue S&T are important. The perception of the utility and importance of S&T both in and out of school may also play an important role in these decisions. Minor pedagogical preferences were also found in certain age groups.

    Recent reports show a sharp increase in smoking rates among girls. We describe prevalence of cigarette smoking and susceptibility to cigarette smoking among female students aged 13 to 15 years in Vietnam and examine the associated factors. We used data from female secondary school students aged 13 to 15 years (grades 8-10) from the 2007 Global Youth Tobacco Survey that was conducted in 9 provinces in Vietnam. We used multivariate logistic regression analysis to determine associations between independent variables with smoking status and susceptibility to smoking. Prevalence of cigarette smoking among girls was 1.2% (95% confidence interval [CI], 0.9-1.5), and 1.5% (95% CI, 1.2-1.9) of girls were susceptible to smoking. Having friends who smoke was the strongest predictor of both smoking status and susceptibility to smoking. Attendance at school classes that described the harmful effects of smoking had significant effects in reducing cigarette smoking. Girls who were exposed to billboard cigarette advertising were more likely to be susceptible to smoking than were those who had not seen advertisements. Our findings highlight the need for pursuing school-based intervention programs in Vietnam and for countering tobacco advertising and marketing practices that target young women.

    2009-03-01

    This study applied self-determination theory to investigate the effects of students' autonomous motivation and their perceptions of teacher autonomy support on need satisfaction adjustment, learning achievement, and cardiorespiratory fitness over a 4-month personal conditioning unit. Participants were 253 urban adolescents (121 girls and 132 boys, ages = 12-14 years). Based on a series of multiple regression analyses, perceived autonomy support by teachers significantly predicted students'need satisfaction adjustment and led to learning achievement, especially for students who were not autonomously motivated to learn in physical education. In turn, being more autonomous was directly associated with cardiorespiratory fitness enhancement. The findings suggest that shifts in teaching approaches toward providing more support for students' autonomy and active involvement hold promise for enhancing learning.

    Full Text Available Breast cancer is the major cause of cancer death in women worldwide. The most common site of metastasis is bone. Bone metastases obstruct the normal bone remodeling process and aberrantly enhance osteoclast-mediated bone resorption, which results in osteolytic lesions. 15-deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2 is an endogenous ligand of peroxisome proliferator-activated receptor gamma (PPARγ that has anti-inflammatory and antitumor activity at micromolar concentrations through PPARγ-dependent and/or PPARγ-independent pathways. We investigated the inhibitory activity of 15d-PGJ2 on the bone loss that is associated with breast cancer bone metastasis and estrogen deficiency caused by cancer treatment. 15d-PGJ2 dose-dependently inhibited viability, migration, invasion, and parathyroid hormone-related protein (PTHrP production in MDA-MB-231 breast cancer cells. 15d-PGJ2 suppressed receptor activator of nuclear factor kappa-B ligand (RANKL mRNA levels and normalized osteoprotegerin (OPG mRNA levels in hFOB1.19 osteoblastic cells treated with culture medium from MDA-MB-231 cells or PTHrP, which decreased the RANKL/OPG ratio. 15d-PGJ2 blocked RANKL-induced osteoclastogenesis and inhibited the formation of resorption pits by decreasing the activities of cathepsin K and matrix metalloproteinases, which are secreted by mature osteoclasts. 15d-PGJ2 exerted its effects on breast cancer and bone cells via PPARγ-independent pathways. In Balb/c nu/nu mice that received an intracardiac injection of MDA-MB-231 cells, subcutaneously injected 15d-PGJ2 substantially decreased metastatic progression, cancer cell-mediated bone destruction in femora, tibiae, and mandibles, and serum PTHrP levels. 15d-PGJ2 prevented the destruction of femoral trabecular structures in estrogen-deprived ICR mice as measured by bone morphometric parameters and serum biochemical data. Therefore, 15d-PGJ2 may be beneficial for the prevention and treatment of breast cancer

    To estimate the mean age of sexual intercourse debut (SID) and associated family and individual factors in 14-19-year-olds of both sexes in the 32 states of Mexico in 2007. A cross-sectional study was conducted of a representative sample of 9,893 students aged between 14 and 19 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire. Logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (95%CI) by category: no SID, SID at 10-15 years and SID at 16-19 years. The national mean age of SID was 16 years, being 15 years for boys (95%CI: 15.88-16.11) and 16 years for girls (95%CI: 15.26-15.42). Factors associated with SID in boys were disadvantaged socioeconomic level (OR=0.66; 95%CI: 0.46-0.94), living with parents (OR=0.65; 95%CI: 0.56-0.75), less offensive communication between parents and boys/girls (OR=0.66; 95%CI: 0.57-0.77), and high social self-esteem (OR=1.68; 95%CI: 1.35-1.77). Factors associated with SID in girls were traditional gender beliefs (OR=0.49; 95%CI: 0.32-0.74), high depressive symptoms (OR=1.88; 95%CI: 1.19-2.99), and high family self-esteem (OR= 0.50; 95%CI: 0.38-0.65). In Mexico, SID occurred early in boys. In addition, the findings of this study show that in Mexico, the age of SID and associated factors differ in boys and girls. The age of SID is strongly influenced by gender and cultural beliefs. Copyright © 2015 SESPAS. Published by Elsevier Espana. All rights reserved.

    To analyze the secular trends of height among Chinese students aged 17 in different ethnic minorities from 1985 to 2010. A total of 18 Chinese ethnic minorities' students, including Mongolian, Hui, Uygur, Zhuang, Korean, Tibetan, Miao, Buyi, Dong, Bai, Tujia, Hani, Dai, Lisu, Wa, Nakhi, Tu and Qiang as subjects were sampled from the 1985, 1995, 2000, 2005 and 2010 Chinese National Surveys on Students' Constitution and Health. The heights of 17 years old people by gender in various ethnic minorities were analyzed and compared. From 1985 to 2010, the increments of adult heights increased significantly in many ethnic minorities' boys. In 2010, the average height of boys aged 17 years in each minority group was higher than 162 cm and was higher than 170 cm among boys from Hui, Mongolian and Korean groups. The ethnics with height growth rates of more than 2 cm per decade in boys were Hui (2.64 cm/decade) and Dong (2.05 cm/decade) and the ethnics with height growth rates of more than 1 cm per decade were Korean (1.99 cm/decade), Tibetan (1.90 cm/decade), Hani (1.80 cm/decade) and the other 9 minority groups. The average height of girls aged 17 years in each minority group was higher than 150 cm in 2010. The heights showed an upward trend in 15 minority groups, but with different degrees. The ethnics with height growth rates of more than 1 cm per decade were Hui (1.56 cm/decade) and Korean (1.29 cm/decade). The increments that were significant between 1985 and 2010 were Hui (3.89 cm), Korean (3.23 cm), Dong (2.35 cm) and the other 6 minority groups (Pminority groups during the past 25 years, but there was an obvious disequilibrium among various ethnic minorities. We should pay more attention to the minority groups with poor growth and give them more help. Meanwhile, we should also pay attention to the negative effects of the secular growth trend on those minority groups with fast increasing adult height.

    This study examined the association between social media and sleep duration among Canadian students aged 11-20. Data from 5242 students were obtained from the 2015 Ontario Student Drug Use and Health Survey, a province-wide, school-based survey that has been conducted every two years since 1977. We measured the respondents' sleep duration against the recommended ranges of 9-11 h per night at 11-13 years of age, 8-10 h at 14-17 and 7-9 h per night for those aged 18 years or more. Overall, 36.4% of students met or exceeded the recommended sleep duration and 63.6% slept less than recommended, with 73.4% of students reporting that they used social media for at least one hour per day. After adjusting for various covariates, the use of social media was associated with greater odds of short sleep duration in a dose-response manner (p for linear trend fashion among Canadian students aged 11-20. ©2018 Foundation Acta Paediatrica.

    Full Text Available The monitoring and recording of the individual characteristics of children are very important for the development of quality education. Also the views of the teachers about the differences in the development, the potentials and the affinities of the children in the early school period are especially important. The quality education process in the modern school should be adapted to the individual potentials of the children. The children are individuals with their own integrity and characteristics. (Johnston and Halocha, 2010. They have individual pace and develop individual approaches in the learning process. This individual pace in the development of the children requires the teachers to regularly monitor and record the individual characteristics and differences of the children, monitoring the children’s interests, planning instruction which will adapt to the different learning approaches and the different pace of progress of the students.Setting out from this paradigm, this paper, which is based on a realized research, aims to offer findings about the treatment of the individual characteristics of the early school-age children in our country. According to this, we carried out a research in four primary schools in Skopje, which showed us that the teachers lack the appropriate conditions and possibilities to monitor and record the individual characteristics and the specific differences of the students in the early school period.

    Many intervention efforts targeting student drinking were developed to address US college students, which usually involves underage drinking. It remains unclear, if research evidence from these interventions is generalizable to university and college students of legal drinking age, e.g., in Europe. To evaluate the effectiveness of a translated and adapted version of the eCHECKUP TO GO, applied as stand-alone web-based electronic screening and brief intervention (e-SBI), in German university students at risk for hazardous drinking. A fully automated web-based two-arm parallel-group randomized controlled trial was conducted. Participants were randomized to an e-SBI or assessment-only (AO) condition. The current paper analyzed students with baseline AUDIT-C scores ≥3 for women and ≥4 for men (sample at baseline: e-SBI [n=514], AO [n=467]; 3-month follow-up: e-SBI [n=194], AO [n=231]; 6-month follow-up: e-SBI [n=146], AO [n=200]). The primary outcome was prior four weeks' alcohol consumption. Secondary outcomes were frequency of heavy drinking occasions, peak blood alcohol concentration, and number of alcohol-related problems. Mixed linear model analyses revealed significant interaction effects between groups and time points on the primary outcome after 3 and 6months. Compared to students in the AO condition, students in the e-SBI condition reported consuming 4.11 fewer standard drinks during the previous four weeks after 3months, and 4.78 fewer standard drinks after 6months. Mixed results were found on secondary outcomes. The results indicate that evidence on and knowledge of web-based e-SBIs based on US college student samples is transferable to German university students of legal drinking age. However, knowledge of what motivates students to complete programs under voluntary conditions, although rare, is needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To explore demographic differences in awarded marks of the final clinical placement in a physiotherapy undergraduate programme. Retrospective analysis of clinical placement assessment marks. A London university offering clinical placements throughout South East England. 333 physiotherapy students entering physiotherapy training between 2005 to 2009. Marks awarded following assessment using a clinical placement assessment form. The mean mark (SD) for age were standard entry 71 (7.4) vs. mature entry 72 (7.99) (ns); for gender male 72 (8.45) vs. female 71 (7.21) (ns); and ethnicity White British 72 (7.71) vs. ethnic minority 70 (7.01) (p=0.023). No interaction effects were observed between the independent variables and only ethnicity demonstrated a statistically significant effect (mean difference (MD) 2.4% 95%CI 0.5 to 4.3, F=5.24, p=0.023). This difference was maintained in most subcategories. Significant differences were observed for the interpersonal section (MD 2.21% 95%CI 0.14 to 4.28, F=4.409, p=0.03), the clinical reasoning section (MD 2.39% 95%CI 0.53 to 4.25, F=6.37, p=0.012) and the treatment section (MD 2.93 95%CI 1.10 to 4.83, F=9.198, p=0.003). Physiotherapy students from minority ethnic backgrounds were awarded a significantly lower mark than their white majority peers in final clinical placements, although the difference was small. Potential reasons are considered, with the strongest recommendation being for further enquiry into the potential relationship between ethnicity and success in undergraduate physiotherapy education.

    As in many advanced societies, the age at first birth and the rate of post-menopausal pregnancies in Israel are constantly increasing. Since Israeli university students are the most likely population to postpone parenthood, this study aims at evaluating their awareness of: (i) women's age-related fertility decline; (ii) age-dependent success rates of IVF technology and (iii) medical procedures allowing late and post-menopausal pregnancies. Israeli undergraduate students (n= 410), attending four academic institutions and studying in different fields, completed a structured questionnaire in the 2009/2010 academic year. Students overestimated women's chances of spontaneous pregnancy in all age groups, whereas women's chances of achieving a live birth following IVF treatment were overestimated only for ages 40 years and above. Regarding both spontaneous and IVF pregnancies, success rates of very late pregnancies (beyond 45 years and after menopause) were greatly overestimated. Only 11% of the students knew that genetic motherhood is unlikely to be achieved from the mid-40s onward, unless using oocytes frozen in advance. The findings demonstrate entrenched fertility myths among Israeli students, particularly the false belief in the possibility of late (beyond 35 years) and very late genetic motherhood. This can be explained by technological 'hype' and favorable media coverage of very late pregnancies. Since this may culminate in involuntary childlessness, it is highly important to increase the awareness of the Israeli public on the subject of fertility. However, as our sample is not representative of the Israeli student population, our findings should be tested in future studies.

    Drawing on a 2-wave longitudinal sample spanning 40 years from childhood (age 12) to middle adulthood (age 52), the present study was designed to examine how student characteristics and behaviors in late childhood (assessed in Wave 1 in 1968) predict career success in adulthood (assessed in Wave 2 in 2008). We examined the influence of parental socioeconomic status (SES), childhood intelligence, and student characteristics and behaviors (inattentiveness, school entitlement, responsible student, sense of inferiority, impatience, pessimism, rule breaking and defiance of parental authority, and teacher-rated studiousness) on 2 important real-life outcomes (i.e., occupational success and income). The longitudinal sample consisted of N = 745 persons who participated in 1968 (M = 11.9 years, SD = 0.6; 49.9% female) and 2008 (M = 51.8 years, SD = 0.6; 53.3% female). Regression analyses and path analyses were conducted to evaluate the direct and indirect effects (via education) of the predictors on career success. The results revealed direct and indirect influences of student characteristics (responsible student, rule breaking and defiance of parental authority, and teacher-rated studiousness) across the life span on career success after adjusting for differences in parental SES and IQ at age 12. rd (c) 2015 APA, all rights reserved).

    Critical thinking is an important characteristic to develop in respiratory care students. We used the short-form Watson-Glaser Critical Thinking Appraisal instrument to measure critical-thinking ability in 55 senior respiratory care students in a baccalaureate respiratory care program. We calculated the Pearson correlation coefficient to assess the relationships between critical-thinking score, age, and student performance on the clinical-simulation component of the national respiratory care boards examination. We used chi-square analysis to assess the association between critical-thinking score and educational background. There was no significant relationship between critical-thinking score and age, or between critical-thinking score and student performance on the clinical-simulation component. There was a significant (P = .04) positive association between a strong science-course background and critical-thinking score, which might be useful in predicting a student's ability to perform in areas where critical thinking is of paramount importance, such as clinical competencies, and to guide candidate-selection for respiratory care programs.

    Alcohol use, reasons for use, and consequences of use continue to be a major concern in college student populations. This is especially true for students of legal drinking age who may experience different reasons for and greater negative consequences of alcohol use than students under 21 years old. Although multiple studies have used person-centered approaches to understand motivations for and ultimately prevent alcohol use, few have identified multiple typologies of reasons for alcohol use. The current study used latent class analysis to identify homogeneous subtypes of reasons for alcohol use and how classification was associated with alcohol-related consequences in college students aged 21 years old and older (N = 2300) from the 2013 Indiana College Substance Use Survey. Four profiles of reasons for alcohol use emerged across males and females: social drinkers, feel good drinkers, relaxed escaping drinkers, and emotion coping drinkers. Although the likelihood of consequences differed across gender, the emotion coping drinkers were more likely to experience all negative consequences, suggesting that it was a high-risk class. In general, this pattern of risk continued with the feel good drinkers and female relaxed escaping drinkers. These results can help optimize college substance use prevention and intervention efforts to (1) identify and understand characteristics of high- and low-risk student drinkers and (2) tailor the content of interventions to those specific profiles resulting in more effective approaches to reducing alcohol use.

    The purpose of this paper is twofold: to validate the properties of the Italian version of the Baller Identity Measurement Scale (i.e., BIMS-IT), a self-report questionnaire based on the athletic and academic identities; and to investigate differences in psychosocial factors such as gender, age, type of sport, and competition level. The dimensionality of the BIMS-IT was explored by means of the exploratory factor analysis, considering the scale's internal consistency too (Confirmatory Factor Analysis). Results related to exploratory and confirmatory factor analysis supported a model of measurement composed of two correlated factors: the athletic and academic identities and affectivity related to identities. For both factors, differences emerged between age, and competition level sub groups. In particular, higher identity scores emerged for ≤ 24 years old student-athletes with respect to their age counterparts. National sub-elite student-athletes reported lower identity values than those of national elite and international levels. Results suggest that the Italian version of the BIMS-IT is psychometrically robust and could be adopted for empirical uses. The higher identity scores reported by younger and higher competition level participants suggest a correspondent higher involvement into the student-athlete role. However, BIMS-IT represents a distinct model with respect to the original American BIMS, determining the need of further research on the student-athletes' identity to better clarify any socio-cultural contest effects.

    During the past five decades there has been an increased in the prevalence of obesity and over weight, also in physical inactivity and /or low cardiorespiratory fitness within the population in school age from diverse regions of the planet, including Bogota-Colombia. The general objective of this study was to compare the physical condition and the levels of physical activity from students who belonged to two curriculum programs of the Public Schools Network from Bogota, one of which includes two sessions per week, each session of 90 minutes of physical activity. We developed a research of unlike cross-sectional groups. There were 178 children evaluated from the regular curriculum and 170 kids belonging to the program 40 x 40. The physical condition was evaluated applying the protocol of high priority from the ALPHA -Fitness test Battery. The weight, height, body mass index, the waist circumference, the standing long jump, the handgrip in both hands and the motor fitness 20 meter shuttle run test were developed under standardized conditions. The Global School Health Survey (GSHS) was used to evaluate the levels of AF. No significant statistical differences were founded between P-40x40 and the regular curriculum regarding: weight, height, the body mass index, the waist circumference, the handgrip in both hands and the explosive strength in lower limbs. Nevertheless the cardiorespiratory fitness was significantly lower within de P-40x40. In conclusion the participation in the curricular program 40 x 40 was not associated with better levels of physical condition. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

A cross-sectional study was carried out in a representative sample of youth aged 16 and 18 years (N=2983) in 8 voivodeships in Poland. The frequency of five atherosclerosis risk factors and their coexistence (≥3) was examined using self-reported questionnaires, in relation to gender, age and school type. Logistic regression analyses were used to assess the influence of the variables (gender, age and school type) on odds ratios of risk factor coexistence. Low physical activity was the most common risk factor, statistically more frequent in students from Basic Vocational Schools than in other school types (pSchools there was also the highest percentage of cigarette smokers (pSchools. The highest risk factor accumulation (≥3) was observed among students from Basic Vocational Schools (40%), significantly more frequent in girls than boys (47.5% and 37.5% respectively). Multivariable analyses show that students from Basic Vocational Schools had twice the odds (OR=2.25, pcoexistence of risk factors for atherosclerosis as compared with students from General Upper Secondary Schools, girls had almost twice as many occurrences (OR=1.83, pschool types requires precise definition of priority health promotion activities depending on school type. 2.

    Full Text Available Objective: Handedness is the most prominent behavioral asymmetry in human. The term of hand preference points to prefer hand or functional asymmetry in manual tasks. The items were considered in this study were: the comparison of handedness between normal and congenitally deaf students the effects of age, sex, and pressure on using right hand for unimanual tasks on handedness the frequency of left-handers among student’s families, the influence of hand preference on English language capabilities, and the point of view of people rather to left-handers have been investigated. Materials & Methods: This cross-sectional comparative study was conducted on 760 students including 380 normal students and 380 deaf students with congenital severe or profound sensory-neural hearing loss from 12 to 18 years of age by that were selected purposefully, completing Edinburg handedness inventory in Tehran. The students didn’t have any confirmed diseases or neurological disorders, except hearing loss in deaf student. Data were gathered through the completion of the Edinburg Handedness Inventory by the students. The student’s aural records and also the confirmation of the audiologist in the deaf schools were considered in order to determine the kind and degree of hearing loss. Results: The prevalence of left-handedness among normal (9.7% and deaf (10.3% students were near to each other, and there was no significant difference between them (P=0.901, z=-1.24. The prevalence of left-handedness was higher in boys rather than girls, but there was no significant influence of sex and age on results (P>0.05. The family and/or teacher pressure for using right hand was 16.0% in normal students and 5.0% in deaf students, and they didn’t report any strict pressure or severity regard this mater. The frequency of left-handers was higher among family of normal students (22.6% than deaf students (13.2%, and the difference between them was significant statistically (P=0

    Objectives: To determine the vaccination status for hepatitis B and knowledge, attitude and practice (KAP) regarding hepatitis B and C among medical students of Karachi and to evaluate the effects of gender and age on the responses, regarding vaccination and KAP for Hepatitis B and C. Methods: This cross sectional study was conducted in 7 medical colleges/ universities of Karachi. Convenient sampling was used to collect the information. Questionnaire regarding awareness about prevention, transmission, diagnosis, treatment and vaccination availability for hepatitis B and C was completed from each individual. In addition, vaccination status of hepatitis B and the awareness of students regarding post exposure prophylaxis was also documented. One thousand five hundred and nine students participated in this study. Results: The mean age of medical students (1509) was 20.35 +- 1.72 years. Female participants were 1075 (71.2%) and 937 62.1%) of the respondents were studying in public institutions. Eighty five percent of the respondents indicated that they were aware of availability of a vaccine for hepatitis B. Only 57.1% medical students showed excellent knowledge regarding the route of spread of hepatitis B and C. Students showing good knowledge of treatment procedures for hepatitis B and C were 48.2%. Half of the respondents (49.8%) showed good knowledge regarding spread of hepatitis by dental procedures. Seventy six percent of participating medical students did not have any knowledge about the post exposure prophylaxis for hepatitis B and C. Seventy four percent indicated that the hepatitis patients should not be isolated. Seventy nine percent of the students reported that they were vaccinated for hepatitis B and 70.6% of them were completely vaccinated (3 doses). About half of the respondents (49.4%) indicated that they were screened for hepatitis B and only 27.1% were screened for hepatitis C. Half of the students reported that they have had needle pricks in their

    The development of a method is described for the preparation and purification of (5,6,8,9,11,12,14,15(n)-/sup 2/H)arachidonic acid (/sup 2/H/sub 8/-AA). The /sup 2/H/sub 8/-AA was chemically synthesised by the selective reduction of 5,8,11,14-eiconsatetraynoic acid (ETYA) with deuterium gas. Using reversed-phase partition chromatography on a Lipidex 5000 column support, it was shown that: (1) The reaction products could readily be separated from each other to yield /sup 2/H/sub 8/-AA of greater than 98% mass purity by gas chromatography. (2) Closely related C20 cis-ethylenic fatty acids differing only in the degree of unsaturation are efficiently separated. The resolution increases exponentially on saturation of double bonds. (3) Commercially available (5,6,8,9,11,12,14,15(n))octatritium-labelled arachidonic acid (/sup 3/H/sub 8/-AA) was readily purified. Both (/sup 3/H/sub 8/)- and (1-/sup 14/C)arachidonic acid (/sup 14/C-AA) co-chromatographed with /sup 2/H/sub 8/-AA. (4) The mass spectra of the methyl ester and trimethylsilyl ester of the purified /sup 2/H/sub 8/-AA showed molecular ions at m/e 326 and 384, respectively.

    Electrical conductivity (σ), differential scanning calorimetry (DSC), and X-ray diffraction (XRD) measurements of n-C x H (2x+1) OSO 3 Li (x= 12, 14, 16, 18, and 20) crystals were performed as a function of temperature. In addition, σ, DSC, and XRD observations of n-C x H (2x+1) OSO 3 Na and n-C x H (2x+1) OSO 3 K (x= 12, 14, 16, 18, and 20) crystals were carried out for comparison. DSC results of the salts revealed several solid-solid phase transitions with large entropy changes (ΔS). For n-C 18 H 37 OSO 3 Li and n-C 20 H 41 OSO 3 Li salts, each melting point produced a small ΔS mp value compared with the total entropy change in the solid phases (ΔS tr1 +ΔS tr2 ). Additionally, Li + ion diffusion was detected in the highest temperature solid phases. For K salts, larger σ values were detected for potassium alkylsulfates compared with those reported for alkyl carboxylate. 7 Li NMR spectra of n-C 18 H 37 OSO 3 Li crystals recorded in the low-temperature phase showed large asymmetry parameters, suggesting the Li + ions are localized at asymmetric sites in the crystals

  1. Use of the Hage framework for theory construction: Factors affecting glucose control in the college-aged student with type 1 diabetes.

    This article describes the Hage framework for theory construction and its application to the clinical problem of glycemic control in college-aged students with type 1 diabetes. College-aged students with type 1 diabetes struggle to self-manage their condition. Glycated hemoglobin (HbA1c), if controlled within acceptable limits (6-8%), is associated with the prevention or delay of serious diabetic complications such as kidney and cardiovascular disease. Diabetes educators provide knowledge and skills, but young adults must self-manage their condition on a daily basis, independent of parents. The Hage framework includes five tasks of theory construction: narrowing and naming the concepts, specifying the definitions, creating the theoretical statements, specifying the linkages, and ordering components in preparation for model building. During the process, concepts within the theory were revised as the literature was reviewed, and measures and hypotheses, foundational to research, were generated. We were successful in applying the framework and creating a model of factors affecting glycemic control, emphasizing that physical activity, thought of as a normal part of wellness, can be a two-edged sword producing positive effect but also serious negative effects in some college-aged students with type 1 diabetes. Contextual factors important to self-management in college-aged students are emphasized. The Hage framework, already used to a small extent in nursing curricula, deserves more attention and, because of its generic nature, may be used as a template for theory construction to examine a wide variety of nursing topics.

    Tobacco use is the world's leading cause of preventable morbidity and mortality, resulting in nearly 6 million deaths each year (1). Smoked tobacco products, such as cigarettes and cigars, are the most common form of tobacco consumed worldwide (2), and most tobacco smokers begin smoking during adolescence (3). The health benefits of quitting are greater for persons who stop smoking at earlier ages; however, quitting smoking at any age has health benefits (4). CDC used the Global Youth Tobacco Survey (GYTS) data from 61 countries across the six World Health Organization (WHO) regions from 2012 to 2015 to examine the prevalence of current tobacco smoking and desire to quit smoking among students aged 13-15 years. Across all 61 countries, the median current tobacco smoking prevalence among students aged 13-15 years was 10.7% (range = 1.7%, Sri Lanka to 35.0%, Timor-Leste). By sex, the median current tobacco smoking prevalence was 14.6% among males (range = 2.9%, Tajikistan to 61.4%, Timor-Leste) and 7.5% among females (range = 1.6%, Tajikistan to 29.0%, Bulgaria). In the majority of countries assessed, the proportion of current tobacco smokers who desired to quit smoking exceeded 50%. These findings could be used by country level tobacco control programs to inform strategies to prevent and reduce youth tobacco use (1,4).

    To assess medical students' and house staff's knowledge and personal and professional perceptions of age-related fertility and fertility preservation before and after an educational intervention. Pre-/post intervention survey. University-based medical center. Medical students and house staff. An educational session on age-related fertility decline and elective fertility preservation. Knowledge scores and perceptions assessed immediately before and after the intervention. Sixty-five surveys were administered. Of the 53 respondents, 71.7% were married or in a committed relationship; 89.4% reported that they were delaying childbearing, with career and/or education being the most frequently listed reason (85.7%); 39.5% indicated that they had both personal and professional interest in fertility preservation but identified finances (62.5%) and time (59.4%) as barriers; 86.9% indicated previous exposure, with formal education (80.0%) and social media (40.0%) being the most common sources. Mean scores on a six-question knowledge-based assessment improved significantly following the presentation (54.6 ± 19.0% vs. 78.1 ± 16.0%), as did the number of participants who indicated that they might now recommend elective oocyte cryopreservation to others (71.1% vs. 54.3%). After the intervention, 97.8% thought that it was important for medical professionals to be informed about age-related fertility decline and elective oocyte cryopreservation. Despite professional and personal interest, knowledge of age-related fertility decline and elective fertility preservation is limited among medical students and house staff. This study highlights the need for formal education across all levels of training and specialties, with even brief interventions being of potential benefit.

    The absorption spectra of microcrystalline salts of cis-[Cr(cycb)(O 2 CO)] + (cycb=rac-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) have been measured between 13,000 and 50,000 cm -1 at temperatures down to 2 K. The vibrational intervals of the electronic ground state were extracted by recording emission and far-IR spectra. The zero-phonon line in the sharp-line absorption spectrum splits into two components by 144 cm -1 . The nine electronic bands due to spin-allowed and spin-forbidden transitions were assigned. Using the observed transitions, a ligand-field analysis has been performed to probe the ligand-field properties of carbonato group in the chromium(III) complex. It is found that the carbonato oxygen has moderately strong σ- and π-donor properties toward chromium(III) ion

  14. A mixed-age science collaborative between elementary and high school physics students: A study of attitude toward school science and inquiry skill

    Science.gov (United States)

    Blain, Mary Perron

    Grade three students had significant improvements in inquiry ability and attitude toward school science as a function of their participation in mixed-age dyads completing inquiry-based science experiments with a high school physics partner. The social interaction between the 'more capable other' (Vygotsky, 1978) with the grade three student in the mixed-age problem solving team indicates a contributing factor in this improvement. This study employed a quasi-experimental design with intact groups of non-random assignment. The non-parametric Wilcoxon test (p = 0.025) was used to analyze scores for each academic achievement group for significant differences pre- and post-collaborative in "Inquiry" skill and "Attitude" toward school science scores. Three grade three classrooms from one elementary school and one high school physics class from the same school district were involved in the study. The high school physics class teamed with one intact grade three class as the mixed-age dyad performing the "hands-on" experiments (treatment). The two grade three classes teamed as same-age peer dyads (comparison group) to perform the same experiments on the same day. Using methods patterned after the way scientists investigate their world, the dyads performed experiments considered for future grade three national assessments (NAEP, 1994), i.e. "Which paper towel holds the most water?"; "Which magnet is stronger?"; "Which type of sugar, cubed or loose, dissolves best in warm water?" Trained raters scored the written lab reports using standardized scoring guides and characteristic benchmark responses to determine the "Inquiry" skill score for each subject. The "Attitude" toward school science score for each subject was determined from the Likert scale survey, Individual and Group Attitudes Toward Science and the open-ended Sentence Completion Test (SCT) (Piburn & Sidlick, 1992). Three raters scored the SCT survey for each subject. This study showed that for a grade three student

    Objectives The present study sought to characterize the degree of general satisfaction with life and degree of satisfaction on four domains: health, physical capacity, mental capacity and social involvement, and to determine the characteristics of self-reports of individuals enrolled on the program in relation to their psychological well-being focusing on the dimensions: autonomy, personal growth, control, positive relationships with others, purpose, personal acceptance and generativity, and to analyse the effect of time studying on level of well-being. Method A total of 140 elderly students of a University for the Third Age took part in the study. The Global Satisfaction With Life Scale and the Self Development Scale (with six psychological well-being subscales) were applied. Continuous variables for the two groups were compared using the Mann-Whitney test. Spearman’s correlation coefficient was used to analyze the relationship among numeric variables. Internal consistency of the instrument scales was analysed by calculating Cronbach’s alpha coefficient. Results Results showed that students who had attended the University of the Third Age for six months or longer had a higher level of satisfaction with life and greater psychological adjustment compared with new entrants to the same institution. Conclusion The study results confirmed the positive effects of continuing education on the well-being of elderly and its contribution to successful aging. PMID:29213747

    2015-12-01

    For decades, role-play and simulation exercises have been utilized for learning and policy decision making. While the power of Model UN simulations in building first-person experience and understanding of complex international issues is well known, the effectiveness of simulations for inspiring citizen engagement in scientific public-policy issues is little studied. My work hypothesizes that climate-change negotiation simulations can enhance students' scientific literacy and policy advocacy. It aims to determine how age and gender influence the responsiveness of students to such simulations. During the 2015 fall semester, I am conducting World Climate exercises for fellow graduate and undergraduate students at San Francisco State University. At the end of the exercise, I will have collected the responses to an anonymous questionnaire in which the participants indicate age and gender. The questionnaire asks participants to describe their hopes and fears for the future and to propose public and personal actions for achieving a strong climate change agreement. I am tracking differences to determine whether participants' age and gender correlate with particular patterns of feeling and thinking. My future research will aim to determine whether and how strongly the World Climate Exercise has affected participants' actual policy engagement. This work will also reflect on my experiences as a World Climate facilitator. I will describe the facilitation process and then discuss some of my observations from the sessions. I will specify the challenges I have encountered and suggest strategies that can strengthen the learning process. World Climate is a computer-simulation-based climate change negotiations role-playing exercise developed by Climate Interactive in partnership with the System Dynamics Group at the MIT Sloan School of Management.

    Interdependent self-construal, collective self-esteem, age, and gender were used to predict attitudes toward seeking professional psychological help among a sample of junior high, high school, and college students in Taiwan (N = 594). Self-construal, collective self-esteem, and help-seeking attitudes were measured by the Self-Construal Scale (T. M. Singelis, 1994), the Collective Self-Esteem Scale Revised (R. Luhtanen & J. Crocker, 1992), and the Attitudes Towards Seeking Professional Psychological Help Scale (E. H. Fischer & J. L. Turner, 1970), respectively. By using stepwise regression, each of the independent factors with the exception of age significantly predicted the dependent variable, professional psychological help-seeking attitudes. Implications for counseling and future research are addressed.

    2008-12-01

    The Association of Southeast Asian Nations (ASEAN) has made tobacco use prevention a primary health issue. All ASEAN countries except Indonesia have ratified the World Health Organization Framework Convention on Tobacco Control (WHO FCTC), the world's first public health treaty on tobacco control. Global Youth Tobacco Survey (GYTS) data were collected from representative samples of students in school grades associated with ages 13-15 in Cambodia, Indonesia, Laos (Vientiane), Malaysia, Myanmar, Philippines, Singapore, Thailand and Vietnam (Hanoi). Current cigarette smoking ranged from less than 5% (Vietnam and Cambodia) to 20.2% in Malaysia. Current use of tobacco products other than cigarettes was less than 10% in all countries. Boys were significantly more likely than girls to smoke cigarettes or use other tobacco products. Exposure to second-hand smoke in public places was greater than 50%, direct pro-tobacco advertising exposure was greater than 75% and over 10% of students were exposed to indirect advertising. Over 60% of students who currently smoked cigarettes wanted to stop, but 80% who tried to quit in the year prior to the survey failed. Efforts to reduce the current and projected harm caused by tobacco use in the ASEAN countries are urgently needed. ASEAN countries need to expand their national comprehensive tobacco prevention and control programs and enforce those laws already passed. Without this effort little reduction can be expected in the burden of chronic diseases and tobacco-related mortality.

    Schools can implement evidence-based sun protection policies that guide practices to help protect children from harmful sun exposure. This national study assessed the relationship between the existence and comprehensiveness of written policies and the comprehensiveness of sun protection practices. The impact of school demographics on the strength of the relationship was also examined, as was the possibility that 'SunSmart' membership would have an additional impact on practices, beyond having any formal policy. In 2011-12, staff members of 1573 schools catering to primary-age students completed a self-administered survey about sun protection policies and practices (response rate of 57%). Results showed that schools with a written policy had more comprehensive practices than schools without a written policy. The relationship between having a written policy and sun protection practices was stronger for remote schools compared with metropolitan and regional schools, and for schools catering to both primary and secondary students compared with primary students only. In addition, policy comprehensiveness was associated with practice comprehensiveness, and SunSmart membership was indirectly related to practice comprehensiveness via policy comprehensiveness. These results indicate that written policies relate to practice comprehensiveness, but the strength of the association can vary according to the characteristics of the organization.

    The aim of the study was to identify personal resources, including health-related resources, sense of self-efficacy, attitude to life (optimism/pessimism) and self-assessment, and to determine their relationship with satisfaction with life in members of the Universities of the Third Age (U3As) in Poland. The impact of sociodemographic factors was analyzed. The study included 320 participants of U3As; their mean age was 67.5 years and the vast majority of them were women (92.5%). The study was a screening test based on a diagnostic survey using validated scales, Satisfaction with Life Scale (SWLS), Life Orientation Test (LOT-R) and Generalized Self-Efficacy Scale (GSES), and a survey of own design. Men showed significantly higher mean SWLS scores than women. SWLS scores were found to correlate significantly with LOT-R ( r =0.411; P <0.001) and GSES scores ( r =0.451; P <0.001). The respondents' financial situation had a significant impact on their scores in all scales: SWLS ( P <0.001), LOT-R ( P <0.001) and GSES ( P <0.001). Educational attainment of the respondents showed a significant correlation with SWLS ( P =0.004) and GSES ( P =0.011). In the process of preparation for successful aging, particular emphasis should be placed on the continuous development of an individual, as it leads to the improvement of their socioeconomic status. Also, promoting positive personality traits and responsibility for one's own life, including health, is of vital importance. The study is particularly important for the early identification of individuals at risk of unsuccessful aging.

    Partial cross-section measurements of (n,n'γ) reactions on natCu were carried out at TUNL using monoenergetic neutrons at six energies of En = 6, 8, 10, 12, 14, 16 MeV. These studies were performed to provide accurate cross-section data on materials abundant in experimental setups involving HPGe detectors used to search for rare events, like the neutrino-less double-beta decay of 76Ge. Spallation and (α,n) neutrons are expected to cause the largest source of external background in the energy region of interest. At TUNL pulsed neutron beams were produced via the 2H(d,n)3He reaction and the deexcitation γ rays from the reaction natCu(n,xγ) were detected with clover HPGe detectors. Cross-section results for the strongest transtions in 63Cu and 65Cu will be reported, and will compared to model calculations and to data recently obtained at LANL with a white neutron beam.

    Tobacco use is a leading preventable cause of morbidity and mortality, with nearly 6 million deaths caused by tobacco use worldwide every year (1). Cigarette smoking is the most common form of tobacco use in most countries, and the majority of adult smokers initiate smoking before age 18 years (2,3). Limiting access to cigarettes among youths is an effective strategy to curb the tobacco epidemic by preventing smoking initiation and reducing the number of new smokers (3,4). CDC used the Global Youth Tobacco Survey (GYTS) data from 45 countries to examine the prevalence of current cigarette smoking, purchase of cigarettes from retail outlets, and type of cigarette purchases made among school students aged 13-15 years. The results are presented by the six World Health Organization (WHO) regions: African Region (AFR); Eastern Mediterranean Region (EMR); European Region (EUR); Region of the Americas (AMR); South-East Asian Region (SEAR); and Western Pacific Region (WPR). Across all 45 countries, the median overall current cigarette smoking prevalence among students aged 13-15 years was 6.8% (range = 1.7% [Kazakhstan]-28.9% [Timor-Leste]); the median prevalence among boys was 9.7% (2.0% [Kazakhstan]-53.5% [Timor-Leste]), and among girls was 3.5% (0.0% [Bangladesh]-26.3% [Italy]). The proportion of current cigarette smokers aged 13-15 years who reported purchasing cigarettes from a retail outlet such as a store, street vendor, or kiosk during the past 30 days ranged from 14.9% [Latvia] to 95.1% [Montenegro], and in approximately half the countries, exceeded 50%. In the majority of countries assessed in AFR and SEAR, approximately 40% of cigarette smokers aged 13-15 years reported purchasing individual cigarettes. Approximately half of smokers in all but one country assessed in EUR reported purchasing cigarettes in packs. These findings could be used by countries to inform tobacco control strategies in the retail environment to reduce and prevent marketing and sales of

    Given the pressure that educators and policy makers are under to achieve academic standards for students, understanding the relationship of academic success to various aspects of health is important. The international Health Behavior in School-Aged Children (HBSC) questionnaire, being used in 41 countries with different school and grading systems, has contained an item assessing perceived school performance (PSP) since 1986. Whereas the test-retest reliability of this item has been reported previously, we determined its convergent and discriminant validity. This cross-sectional study used anonymous self-report data from Austrian (N = 266), Norwegian (N = 240), and Canadian (N = 9,717) samples. Students were between 10 and 17 years old. PSP responses were compared to the self-reported average school grades in 6 subjects (Austria) or 8 subjects (Norway), respectively, or to a general, 5-category-based appraisal of most recent school grades (Canada). Correlations between PSP and self-reported average school grade scores were between 0.51 and 0.65, representing large effect sizes. Differences between the median school grades in the 4 categories of the PSP item were statistically significant in all 3 samples. The PSP item showed predominantly small associations with some randomly selected HBSC items or scales designed to measure different concepts. The PSP item seems to be a valid and useful question that can distinguish groups of respondents that get good grades at school from those that do not. The meaning of PSP may be context-specific and may have different connotations across student populations from different countries with different school systems. © 2012, American School Health Association.

    The study evaluated the validity and reproducibility of the food consumption section of the questionnaire Food Intake and Physical Activity of School Children (Web-CAAFE), an Internet-based software for the qualitative measurement of food consumption by recalling the previous day. A total of 390 students in grades 2 to 5 (7 to 15 years) of a semi-integral public school participated in the study. The validity was tested by comparing the report in the Web-CAAFE and the direct observation of food consumed in the school in the previous day. The reproducibility was evaluated in a sub-sample of 92 schoolchildren, by comparing repeated reports in the Web-CAAFE on the same day. Probabilities of accuracy in the Web-CAAFE report in relation to the observation (matches, omissions and intrusions and respective 95% confidence intervals) among seven food groups were estimated through multinomial logistic regression. The average for the match rate was 81.4% (variation: 62% sweets and 98% beans); for the omission rate was 16.2% (variation between 2.1% dairy products and 28.5% sweets); for the intrusion rate was 7.1% (variation between 1.3% beans and 13.8% cereals). Sweets, cereals and processed foods, snack foods and fried foods simultaneously exhibited higher rates of omission and intrusion. Students 10 years of age or older had lower probabilities of intruding food items. There were no significant variations in the accuracy of the report between repeated measures. The Web-CAAFE was a valid and reliable instrument for the evaluation of food consumption, when applied to students in grades 2 to 5 of public schools.

    There have only been a few publications focussing on how the curriculum Q7 "medicine of aging and the elderly" is implemented at German medical schools. In order to stimulate discussion about the implementation of Q7 the authors present the results of a survey of medical students of the Charité - Universitätsmedizin Berlin. The aim of the survey was to identify items that contribute to a good course and thus improve the quality of lectures and courses in geriatric medicine with the overall aim to encourage more students to become geriatricians after their studies. Medical students from the fifth clinical semester were interviewed in anonymous form following each course using standardized questionnaires for organizational and didactic topics. Factor analysis, proof of reliability, descriptive statistics and correlation analysis were performed as statistical methods. The proof of reliability of questionnaires showed good internal consistency with Cronbachs alpha values of 0.88 (seminars), 0.91 (lectures) and 0.92 (bedside teaching). The overall response rate was very high (95.3%, n = 803 questionnaires). The ratings for questionnaire items in the three teaching formats (i.e. seminars, lectures, bedside teaching) ranged mostly from good to very good. In the correlation analysis across all three teaching formats clear communication of learning objectives, the treatment of topics according to their own expectations and the learning experience were rated as most relevant overall. The evaluation results indicate a high level of satisfaction with the curriculum of geriatrics at the Charité, which can therefore be recommended across faculties taking into account the criteria named.

    Boarding school student aged 13-18 need to eat nutritious meals which contains proper calories, vitality and nutrients for appropriate development with a specific end goal to repair and upkeep the body tissues. Furthermore, it averts undesired diseases and contamination. Serving healthier food is a noteworthy stride towards accomplishing that goal. However, arranging a nutritious and balance menu manually is convoluted, wasteful and tedious. Therefore, the aim of this study is to develop a mathematical model with an optimization technique for menu scheduling that fulfill the whole supplement prerequisite for boarding school student, reduce processing time, minimize the budget and furthermore serve assortment type of food each day. It additionally gives the flexibility for the cook to choose any food to be considered in the beginning of the process and change any favored menu even after the ideal arrangement and optimal solution has been obtained. This is called sensitivity analysis. A recalculation procedure will be performed in light of the ideal arrangement and seven days menu was produced. The data was gathered from the Malaysian Ministry of Education and schools authorities. Menu arranging is a known optimization problem. Therefore Binary Programming alongside optimization technique and “Sufahani-Ismail Algorithm” were utilized to take care of this issue. In future, this model can be implemented to other menu problem, for example, for sports, endless disease patients, militaries, colleges, healing facilities and nursing homes.

    We previously reported that 15-deoxy-Δ 12,14 -prostaglandin J 2 (15d-PGJ 2 ), the most potent agonist for peroxisome proliferator-activated receptor γ (PPARγ), induces apoptosis of human chondrosarcoma cell line OUMS-27. The current study aimed to explore the mechanism of 15d-PGJ 2 -induced apoptosis and inhibition of cell proliferation in OUMS-27 cells. The preliminary results of cDNA microarray analysis showed the down-regulation of anti-apoptotic Bcl-xL and up-regulation of pro-apoptotic Bax in the process of 15d-PGJ 2 -induced apoptosis. These changes were further confirmed at mRNA and protein levels by RT-PCR and Western blot analysis, respectively. Among cyclin-dependent kinase inhibitors, p21 was induced and up-regulated by 15d-PGJ 2 , but p16 and p27 were not changed, suggesting that the involvement of p21 in inhibition of cell proliferation. Activation of caspase-3 by 15d-PGJ 2 was partly, but not completely, blocked by PPARγ antagonist (GW9662) suggesting the 15d-PGJ 2 exerted its effect by PPARγ-dependent and -independent pathways. Interestingly, immunohistochemical study on human chondrosarcoma samples revealed that Bcl-xL is frequently expressed by tumor cells. The results of the current study suggest that the potential ability of 15d-PGJ 2 in regulation of cell cycle and inhibition of Bcl-xL expression might be beneficial in the development of novel pharmacological agents for chondrosarcoma

    Full Text Available Pregnancy is a complex immunological state in which a bias towards T helper 2 (Th2 protects the fetus. Evidence suggests that proinflammatory cytokines increase the risk of poor neonatal outcome, independently of the direct effect of preterm labour. The anti-inflammatory prostaglandin 15-deoxy-Δ12,14-Prostaglandin J2 (15dPGJ2 inhibits nuclear factor Kappa B (NF-κB in amniocytes and myocytes in vitro and is a ligand for the chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2 receptor. Here we examine the Th1:Th2 cytokine bias in pregnancy and whether 15dPGJ2 could be used to inhibit the production of the proinflammatory cytokines through inhibition of NF-κB while simultaneously promoting Th2 interleukin 4 (IL-4 synthesis via CRTH2 in T helper cells. Peripheral blood mononuclear cells (PBMCs from women at 28 weeks, term pre-labour, term labour as well as non-pregnant female controls were cultured with 15dPGJ2 or vehicle control and stimulated with phorbol myristyl acetate (PMA/ionomycin. The percentage of CD4+ cells producing interferon gamma (IFN-γ and tumor necrosis factor alpha (TNF-α in response to PMA/ionomycin was significantly reduced in pregnancy. 15dPGJ2 reduced IFN-γ and TNF-α production in stimulated T helper cells, but did not alter IL-4 production in CRTH2+ve cells. 15dPGJ2 also reduced phospho-p65 in stimulated PBMCs. In summary, 15dPGJ2 suppresses the Th1 response of PBMCs during pregnancy and active labour whilst maintaining the Th2 response suggesting a therapeutic benefit in reducing neonatal morbidity in inflammation-induced PTL.

  10. Seroprevalence of Trypanosoma cruzi Infection in Students at the Seven-Fourteen Age Range, Londrina, PR, Brazil, in 1995

    Full Text Available Seropositivity for Chagas disease was evaluated in 834 children aged between 7 and 14 from the Municipal Teaching System in the district of Londrina, State of Paraná. A seroprevalence rate of 0.1% was found through the use of an indirect immunofluorescent test and an enzyme-linked immunosorbent assay. This low rate of seroprevalence provides evidence that the vectorial transmission of Chagas disease has been eliminated in Londrina. The main reason for the elimination of vectorial transmission of Trypanosoma cruzi infection, as evaluated by serological tests, may be a remarkable change in the economic structure of the northern region of Paraná in the 1960's. At that time coffee production was almost completely replaced by soy beans, wheat and grazing in the rural areas. This change deeply affected the rural ecology and caused an exodus of the population from rural to urban areas as well as a decrease in the total number of the population of that region. The measures introduced for controlling the disease through the Program of Chagas Disease Control established by the Fundação Nacional de Saúde of the Brazilian Ministry of Health, certainly, had a positive impact on the reduction of American trypanosomiasis prevalence in the area under study. However, it does not seem that this was the most relevant factor responsible for the elimination of vectorial transmission of Chagas disease in Londrina.

    Truancy among adolescents may negatively affect the achievement of academic goals. The aim of the study was to investigate the prevalence and correlates of school truancy in the Association of Southeast Asian Nations (ASEAN) member states. The analysis included 28 419 school children aged 13-15 years from seven ASEAN member states that participated in the Global School-based Student Health Survey (GSHS) between 2007 and 2013. The overall prevalence of past 30 day truancy across six ASEAN countries (excluding Brunei) was 24.8%; ranging from below 20% in Myanmar, Thailand, and Vietnam to more than 30% in Brunei Darussalam, Indonesia, and the Philippines. In multivariable logistic regression analysis, socio-demographic factors (older age, being male, the experience of hunger), externalising behaviour (tobacco use, alcohol use, having been in a physical fight, being bullied, having sustained an injury), and lack of protective social-familial factors (lack of peer support and lack of parental or guardian support) were found to be associated with truancy. High rates of truancy were found in ASEAN member states calling for interventions aimed to reduce truancy considering identified associated factors.

    The aim of this study was to assess suicidal ideation and associated factors in school-going adolescents in the Association of Southeast Asian Nations (ASEAN) member states. The analysis included 30,284 school children aged 13-15 years from seven ASEAN countries that participated in the cross-sectional global school-based student health survey (GSHS) between 2007 and 2013. The overall prevalence of suicidal ideation in the past 12 months across seven ASEAN countries was 12.3%, significantly higher in girls (15.1%) than boys (9.3%). Among seven ASEAN countries with the highest prevalence of suicidal ideation was in the Philippines (17.0%) and Vietnam (16.9%) and the lowest in Myanmar (1.1%) and Indonesia (4.2%). In multivariable logistic regression analysis, female gender, older age (14 or 15 years), living in a lower middle income country, having no friends, loneliness, bullying victimisation, having been in a physical fight in the past 12 months, lack of parental or guardian support, tobacco use and having a history of ever got drunk were associated with suicidal ideation. Different rates of suicidal ideation were observed in ASEAN member states. Several risk factors for suicidal ideation were identified which can help guide preventive efforts.

    This paper aims to estimate the prevalence of cigarette smoking among students in Vietnam ages 13-15 and examines its relationship with compositional and contextual factors. The data used in this paper were obtained from the 2007 Global Youth Tobacco Survey conducted in nine provinces in Vietnam. A multilevel logistic regression model was applied to analyse the association between the current incidence of cigarette smoking and factors on both the individual and school level. The prevalence of cigarette smoking among students was 3.3% overall. The prevalence of smoking among male students (5.9%) was higher than that among females (1.2%). Parental smoking was a significant risk factor for smoking among the students. Having a friend who smoked was the strongest predictor of smoking status among the study subjects. We have demonstrated that school-level factors appeared to impact the prevalence of cigarette smoking among students ages 13-15. This paper highlights the importance of utilising an extensive range of actions to prevent students from using tobacco in Vietnam. These actions should include providing specific curricula for students that address both individual characteristics and the school environment. Further, prevention programmes should also target both parental- and peer-smoking issues.

    Prostaglandin metabolite 15-Deoxy-Δ 12,14 -prostaglandin J2 (15d-PGJ2) is known to inhibit a number of pro-inflammatory cytokines as well as being a ligand for nuclear receptor PPARγ. We investigated the ability of 15d-PGJ2 to inhibit TNF-α gene expression through mechanisms that involve histone modification. Pretreatment with 15d-PGJ2 (10 μM) inhibited LPS-stimulated TNF-α mRNA in THP-1 monocytes or PMA-differentiated cells to nearly basal levels. A specific PPARγ ligand, GW1929, failed to inhibit LPS-induced TNF-α mRNA expression nor did a PPARγ antagonist, GW9662, alter the repression of TNF-α mRNA in LPS-stimulated cells pretreated with 15d-PGJ2 suggesting a PPARγ-independent inhibition of TNF-α mRNA in THP-1 cells. Transfection studies with a reporter construct and subsequent treatment with 15d-PGJ2 demonstrated a dose-dependent inhibition of the TNF-α promoter. Additional studies demonstrated that inhibition of histone deacetylases with trichostatin A (TSA) or overexpression of histone acetyltransferase CBP could overcome 15d-PGJ2-mediated repression of the TNF-α promoter, suggesting that an important mechanism whereby 15d-PGJ2 suppresses a cytokine is through factors that regulate histone modifications. To examine the endogenous TNF-α promoter, chromatin immunoprecipitations (ChIP) were performed. ChIP assays demonstrated that LPS stimulation induced an increase in histone H3 and H4 acetylation at the TNF-α promoter, which was reduced in cells pretreated with 15d-PGJ2. These results highlight the ability of acetylation and deacetylation factors to affect the TNF-α promoter and demonstrate that an additional important mechanism whereby 15d-PGJ2 mediates TNF-α transcriptional repression by altering levels of acetylated histone H3 and H4 at its promoter

    College students have been the focus of many studies on suicidal ideation with or without suicidal behavior. Little attention has been given to their non-college-attending peers on these issues. We examined the 12-month prevalence and mental health treatment of suicidal ideation with or without suicidal behavior among college students aged 18-25 years and their non-college-attending peers in the United States. We assessed data from 135,300 persons aged 18-25 years who participated in the 2008-2013 National Surveys on Drug Use and Health. Descriptive analyses and multivariate logistic regression models were applied. Compared with full-time college students, high school students, those not enrolled in a school or college, and part-time college students were more likely to attempt suicide with a plan (model-adjusted prevalence = 0.67% vs 1.09%, 1.06%, and 1.07%, respectively). The mental health treatment rate among full-time college students with suicidal ideation with or without suicidal behavior was similar to the rates among the other 3 counterparts. The effects of race/ethnicity and serious mental illness on receipt of mental health treatment were significantly larger among those who did not perceive unmet treatment need than among those who perceived unmet treatment need (P = .019 and P = .001, respectively). Compared to full-time college students, non-college-attending young adults and part-time college students were at higher risk for attempting suicide with a plan. Suicide prevention and intervention strategies should emphasize increasing access to mental health treatment among both college students with suicidal ideation with or without suicidal behavior and their non-college-attending peers (particularly among minorities and those who seem to be at low risk because they are without serious mental illness and report no need for mental health treatment). © Copyright 2016 Physicians Postgraduate Press, Inc.

  19. Mobility, Mood and Place—Co-Designing Age-Friendly Cities: A Report on Collaborations between Older People and Students of Architecture

    Directory of Open Access Journals (Sweden)

    Iain Scott

    2017-08-01

    Full Text Available Mobility, Mood and Place explores how places can be designed collaboratively to make pedestrian mobility easy, enjoyable and meaningful for older people. The built environment often excludes marginalised groups such as older people, single mothers and others with special needs. ‘Co-design’ is emerging as an important approach in architectural and urban design, which diversifies stakeholder participation and representation. Participatory co-design approaches can include such stakeholders so as to address their priorities and ensure that other stakeholders empathise with their perspective. This can enhance students’ methodological flexibility and empathy. This paper critically reflects on architecture students’ experiences, together with older adults (including stroke-survivors and those with dementia, in producing co-design research on age-friendly environments and offers some methodological insights. It also discusses competing objectives between a co-design research project that involved students of architecture and landscape design on post-graduate academic programmes. Finally, the paper will offer contributions to architects interested in designing places that take into account the needs of older people.

    To assess the trend of sex disparity in hemoglobin concentration and prevalence of anemia among Chinese school-aged children from 1995 to 2010. Data were collected from 360 866 children aged 7, 9, 12, 14, and 17 years during 4 cross-sectional surveys (1995, 2000, 2005, and 2010) of the Chinese National Surveys on Students Constitution and Health. Shifts in hemoglobin concentration distributions were compared by sex. Average shifts and sex differences were calculated with quantile regression models. Logistic regression was used to estimate the prevalence odds ratio of sex for prevalence of anemia in different surveys. The mean hemoglobin concentration increased among Chinese children between 1995 and 2010, from 132.7 to 138.3 g/L in boys, and from 127.7 to 132.3 g/L in girls. The prevalence of anemia decreased from 18.8% in 1995 to 9.9% in 2010. It was higher in rural than urban children among all age groups. The prevalence odds ratios of girls versus boys for anemia increased in both urban and rural areas over time. Hemoglobin concentration and prevalence of anemia improved among Chinese school-aged children over time. Hemoglobin concentration improved faster in boys than girls and as a result the relative prevalence of anemia in girls compared with boys increased. Sex-specific preventive guidelines and public health policies for childhood anemia are needed in China. Copyright © 2017 Elsevier Inc. All rights reserved.

    Our study is the first to describe the prevalence and correlates (demographics, body mass index [BMI], sedentary behaviors, and physical activity) of high school youth who report active videogame playing (active gaming) in a U.S. representative sample. The National Youth Physical Activity and Nutrition Study of 2010 provided data for this study. Active gaming was assessed as the number of days in the 7 days prior to the survey that students in grades 9-12 (14-18 years of age) reported participating in active videogames (e.g., "Wii™ Fit" [Nintendo, Kyoto, Japan], "Dance Dance Revolution" [Konami, Osaka, Japan]). Students reporting ≥1 days were classified as active gamers. Logistic regression was used to examine the association among active gaming and demographic characteristics, BMI, sedentary behaviors, and physical activity. Among 9125 U.S. high school students in grades 9-12 surveyed, 39.9 percent (95 percent confidence interval=37.9 percent, 42.0 percent) reported active gaming. Adjusting for covariates, the following characteristics were positively associated (Pblack, non-Hispanic race/ethnicity; being overweight or obese; watching DVDs >0 hours/day; watching TV >0 hours/day; and meeting guidelines for aerobic and muscle-strengthening physical activity. Four out of 10 U.S. high school students report participating in active gaming. Active gamers tend to spend more time watching DVDs or TV, meet guidelines for physical activity, and/or be overweight or obese compared with nonactive gamers. These findings may serve to provide a baseline to track active gaming in U.S. youth and inform interventions that target sedentary behaviors and/or physical activity.

    Care provided by student doctors and nurses is well received by patients in hospital and primary care settings. Whether the same is true for aged care residents of nursing homes with mild cognitive decline and their family members is unknown. To investigate the perspectives of aged care residents with mild cognitive decline and their family members on interdisciplinary student placements in two residential aged care facilities (RACF) in Tasmania. A mixed methods design was employed with both qualitative and quantitative data collected. All participants were interviewed and completed a questionnaire on residents' quality of life, during or after a period of student placements in each facility (October-November, 2012). Qualitative data were coded for themes following a grounded theory approach, and quantitative data were analysed using SPSS. Twenty-one participants (13 residents and 8 family members) were recruited. Four themes were identified from the qualitative data and included (i) increased social interaction and facility vibrancy; (ii) community service and personal development, (iii) vulnerability and sensitivity (learning to care) and (iv) increased capacity and the confidence of enhanced care. Residents' quality of life was reported to be mostly good in the presence of the students, despite their high care needs. Residents with mild cognitive decline and their family members perceive a wide array of benefits of student provided care in RACFs including increased social interaction. Future quantitative research should focus on whether changes in care occur for residents as a result of student involvement. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    To determine the sexual behavioral pattern, consequences, and adopted solutions among senior secondary schools students in Ojo military barracks, Lagos. This was a cross-sectional study of 400 senior secondary schools students in Ojo military barracks, Lagos, selected using a multistage sampling technique. Data was collected using pre-tested, self-administered semi-structured questionnaires. Data was analysed using statistical package for social sciences version 17. Tests of statistical significance were carried out using χ2-test, and a p-value of sexual intercourse and were influenced mainly by peer pressure (p=0.0000). Their age at first sexual intercourse ranged between 10-19 years. Ten (6.5%) of the respondents (all males) had their sexual debut with a commercial sex worker. More girls 41 (56.2%) than boys 12 (14.8%), were forced into sexual intercourse (p=0.0000). Over half of the sexually active respondents had at least two sexual partners for either sex. Findings from this study have shown that young people living in the barracks indulged in sexual activity at very early ages and engaged in risky sexual behavior. We therefore recommend an improved multi-sectoral approach in reproductive health and sexually transmitted infections including HIV/AIDS education.

    The aim of the present study was to explore the prevalence of adult attention deficit hyperactivity disorder (ADHD) in young adult Iranian students and to examine gender, birth order, socioeconomic status (SES), and history of ADHD as potential predictors of adult ADHD. A total of 387 young adult students (mean age: 19.6 years; 66.3% females) completed the Adult ADHD Self-Report Scale-V1.1 symptom checklist to assess current symptoms of ADHD and the Wender Utah Rating Scale to assess symptoms of ADHD in childhood and adolescence. Experts' ratings were based on Wender-Reimherr Interview. Self-rated and expert-rated prevalence rates were 16.5% and 13.4%, respectively. Past symptoms of ADHD were correlated with current symptoms. Childhood ADHD, current hyperactivity, and disorganization predicted current ADHD. Among a sample of Iranian students, the prevalence rates of ADHD were higher than estimated rates worldwide. Data also show child ADHD to be associated with adult ADHD; gender, age, birth order, and SES did not seem to influence current symptomatology.

    2017-07-01

    Full Text Available Recently, concerns have been raised about the potential effect of head-neck junction damage products at the local and systemic levels. Factors that may affect this damage process have not been fully established yet. This study investigated the possible correlations among head-neck junction damage level, implant design, material combination, and patient characteristics. Head-neck junctions of 148 retrieved implants were analysed, including both ceramic-on-ceramic (N = 61 and metal-on-metal (N = 87 bearings. In all cases, the male taper was made of titanium alloy. Damage was evaluated using a four-point scoring system based on damage morphology and extension. Patient age at implantation, implantation time, damage risk factor, and serum ion concentration were considered as independent potential predicting variables. The damage risk factor summarises head-neck design characteristics and junction loading condition. Junction damage correlated with both implantation time and damage factor risk when the head was made of ceramic. A poor correlation was found when the head was made of cobalt alloy. The fretting-corrosion phenomenon seemed mainly mechanically regulated, at least when cobalt alloy components were not involved. When a component was made of cobalt alloy, the role of chemical phenomena increased, likely becoming, over implantation time, the damage driving phenomena of highly stressed junctions.

    Full Text Available Abstract Background Although social environments may influence alcohol-related behaviours in youth, the relationship between neighbourhood socioeconomic context and effectiveness of school-based prevention against underage drinking has been insufficiently investigated. We study whether the social environment affects the impact of a new school-based prevention programme on alcohol use among European students. Methods During the school year 2004-2005, 7079 students 12-14 years of age from 143 schools in nine European centres participated in this cluster randomised controlled trial. Schools were randomly assigned to either control or a 12-session standardised curriculum based on the comprehensive social influence model. Randomisation was blocked within socioeconomic levels of the school environment. Alcohol use and alcohol-related problem behaviours were investigated through a self-completed anonymous questionnaire at baseline and 18 months thereafter. Data were analysed using multilevel models, separately by socioeconomic level. Results At baseline, adolescents in schools of low socioeconomic level were more likely to report problem drinking than other students. Participation in the programme was associated in this group with a decreased odds of reporting episodes of drunkenness (OR = 0.60, 95% CI = 0.44-0.83, intention to get drunk (OR = 0.60, 95% CI = 0.45-0.79, and marginally alcohol-related problem behaviours (OR = 0.70, 95% CI = 0.46-1.06. No significant programme's effects emerged for students in schools of medium or high socioeconomic level. Effects on frequency of alcohol consumption were also stronger among students in disadvantaged schools, although the estimates did not attain statistical significance in any subgroup. Conclusions It is plausible that comprehensive social influence programmes have a more favourable effect on problematic drinking among students in underprivileged social environments.

    2016-01-01

    The multiple social and performance demands placed on college/university singers could put their still developing voices at risk. Previous ambulatory monitoring studies have analyzed the duration, intensity, and frequency (in Hz) of voice use among such students. Nevertheless, no studies to date have incorporated the simultaneous acoustic voice quality measures into the acquisition of these measures to allow for direct comparison during the same voicing period. Such data could provide greater insight into how young singers use their voices, as well as identify potential correlations between vocal dose and acoustic changes in voice quality. The purpose of this study was to assess the voice use and estimated voice quality of college/university singing students (18–24 y/o, N = 19). Ambulatory monitoring was conducted over three full, consecutive weekdays measuring voice from an unprocessed accelerometer signal measured at the neck. From this signal were analyzed traditional vocal dose metrics such as phonation percentage, dose time, cycle dose, and distance dose. Additional acoustic measures included perceived pitch, pitch strength, LTAS slope, alpha ratio, dB SPL 1–3 kHz, and harmonic-to-noise ratio. Major findings from more than 800 hours of recording indicated that among these students (a) higher vocal doses correlated significantly with greater voice intensity, more vocal clarity and less perturbation; and (b) there were significant differences in some acoustic voice quality metrics between non-singing, solo singing and choral singing.

    To examine the effectiveness of a "cardiopulmonary resuscitation song" in improving the basic life support skills of secondary school students. This pre-test/post-test control design study enrolled secondary school students from two middle schools randomly chosen in Córdoba, Andalucia, Spain. The study included 608 teenagers. A random sample of 87 students in the intervention group and 35 in the control group, aged 12-14 years were selected. The intervention included a cardiopulmonary resuscitation song and video. A questionnaire was conducted at three-time points: pre-intervention, one month and eight months post-intervention. On global knowledge of cardiopulmonary resuscitation, there were no significant differences between the intervention group and the control group in the trial pre-intervention and at the month post-intervention. However, at 8 months there were significant differences with a p-value = 0.000 (intervention group, 95% CI: 6.39 to 7.13 vs. control group, 95% CI: 4.75 to 5.92), F(1,120)=16.644, p=0.000). In addition, significant differences about students' basic life support knowledge about chest compressions at eight months post-intervention (F(1,120)=15.561, p=0.000) were found. Our study showed that incorporating the song component in the cardiopulmonary resuscitation teaching increased its effectiveness and the ability to remember the cardiopulmonary resuscitation algorithm. Our study highlights the need for different methods in the cardiopulmonary resuscitation teaching to facilitate knowledge retention and increase the number of positive outcomes after sudden cardiac arrest.

    The purpose of this study was to understand the diet, drinking, and smoking behaviors of university students and to analyze the health behaviors that could be a risk factor for non-communicable diseases (NCDs) in order to contribute to the promotion of NCD prevention in youth. The survey was carried out using a questionnaire with closed questions including items about health behaviors. The subjects surveyed were students of 10 universities on the main island of Japan (1,196 valid responders). The score for the nutritional balance was significantly low in the group living alone for both students in their teens and 20s. For the frequency of not eating breakfast, results suggest that living alone and increase in age are related to the lack of breakfast for both males and females. Teenage males living alone tended to lack in consideration for the intake of animal fat than those not living alone. The females showed a higher tendency to eat sweets and snacks during the day than the males. For the males who living alone, results suggest that they tended to have a higher or equal alcohol intake to females in their 20s and males in their 20s not living alone even when they are underage. Males in their 20s tended to have a higher amount and frequency of smoking than other groups regardless of their living arrangement. Accumulation of health behavior that could be a risk for NCDs was found in some of the groups, such as males living alone.

All students were examined for gingival index (GI) and plaque index (PI), information about oral hygiene habits was recorded. Only 29.8 % had healthy gingiva, 38.5 % had mild gingivitis, 31.4 % had moderate gingivitis, and 0.3 % had severe gingivitis. The difference between both genders was not statistically significant P > 0.05. 36.8 % of the examined students never brushed their teeth. Average gingival index (GI) and average plaque index (PI) were 0.77 and 0.61 respectively. Fair oral hygiene with mild to moderate gingivitis is highly prevalent among Tafelah school children. This study indicated that oral health status among schoolchildren in Tafelah is poor and needs to be improved. Long-term school based oral health education programme is highly recommended.

To do so three measurement scales (Technological Origin - OTE, Adoption Profile - PAD and Innovator Behavioral Style - ECI were used and to identify the causal relationships among concepts, attitudes and processes of technology adoption among students. The data analysis choice was based on structural equation model (SEM variance based approach or partial least squares (PLS-SEM using the SmartPLS 2.0 software. The general model was tested, comprised by the constructs of the three scales and then a variable which characterizes the respondent’s generation was introduced as moderator. As a result it is possible to state that for the concepts of Digital Native and Digital Immigrant are lacking empirical foundations, simply serving as a rhetorical figure, of easy acceptance and assimilation, but unable to substantiate the existence of a phenomenon or generations effect on the process of diffusion and technology adoption, unlike what is commonly proposed in the literature.

    To identify the factors that influence decisions made by health professionals when assessing the pain of native English speaking and children whose English is an additional language. Pain assessment in children is often poorly executed following acute injury. Whilst a range of pain assessment tools have been developed, little guidance is provided for assessing pain in children with English as an additional language. Factorial survey design. Twenty minor injuries unit nurses and 20 children's nursing students participated in an electronic survey to make judgements on 12 scenarios describing a child attending a minor injuries unit following an incident, accompanied by a parent. Respondents had to decide the most important form of pain assessment, and whether they would ask a parent or an interpreter to assess the pain of the child. An open-ended question asked about the difficulties found in making a judgement. Observation of the child's behaviour was the most common pain assessment reported. The visual analogue scale was significantly associated with children with proficient English. Respondents were significantly more likely to involve parents in the assessment if they could speak English well compared to parents with poor English skills. Moreover, nursing students were significantly more likely than registered nurses to call for support from an interpreter. Thematic analysis identified three themes related to difficulties with pain assessment: contrasting approaches, differing perceptions of pain and overcoming challenges. The reduced ability to communicate between child, parent and healthcare professional highlights the need to identify forms of assessment based on individual cases. The number of children with English as an additional language has seen a marked rise over the last decade. In situations where communication ability is reduced, assessment of pain should be tailored to meet the needs of the child. This may require timely access to interpreter services

For n-C {sub 18}H{sub 37}OSO{sub 3}Li and n-C {sub 20}H{sub 41}OSO{sub 3}Li salts, each melting point produced a small ΔS{sub mp} value compared with the total entropy change in the solid phases (ΔS{sub tr1}+ΔS{sub tr2}). Additionally, Li {sup +} ion diffusion was detected in the highest temperature solid phases. For K salts, larger σ values were detected for potassium alkylsulfates compared with those reported for alkyl carboxylate. {sup 7}Li NMR spectra of n-C {sub 18}H{sub 37}OSO{sub 3}Li crystals recorded in the low-temperature phase showed large asymmetry parameters, suggesting the Li {sup +} ions are localized at asymmetric sites in the crystals.

    Background Schools have been identified as an important place in which to support adolescent emotional health, although evidence as to which interventions are effective remains limited. Relatively little is known about student and staff views regarding current school-based emotional health provision and what they would like to see in the future, and this is what this study explored. Methods A random sample of 296 English secondary schools were surveyed to quantify current level of emotional health provision. Qualitative student focus groups (27 groups, 154 students aged 12-14) and staff interviews (12 interviews, 15 individuals) were conducted in eight schools, purposively sampled from the survey respondents to ensure a range of emotional health activity, free school meal eligibility and location. Data were analysed thematically, following a constant comparison approach. Results Emergent themes were grouped into three areas in which participants felt schools did or could intervene: emotional health in the curriculum, support for those in distress, and the physical and psychosocial environment. Little time was spent teaching about emotional health in the curriculum, and most staff and students wanted more. Opportunities to explore emotions in other curriculum subjects were valued. All schools provided some support for students experiencing emotional distress, but the type and quality varied a great deal. Students wanted an increase in school-based help sources that were confidential, available to all and sympathetic, and were concerned that accessing support should not lead to stigma. Finally, staff and students emphasised the need to consider the whole school environment in order to address sources of distress such as bullying and teacher-student relationships, but also to increase activities that enhanced emotional health.

    We examined the prevalence and associations between behavioral and identity dimensions of sexual orientation among adolescents in the United States, with consideration of differences associated with race/ethnicity, sex, and age. We used pooled data from 2005 and 2007 Youth Risk Behavior Surveys to estimate prevalence of sexual orientation variables within demographic sub-groups. We used multilevel logistic regression models to test differences in the association between sexual orientation identity and sexual behavior across groups. There was substantial incongruence between behavioral and identity dimensions of sexual orientation, which varied across sex and race/ethnicity. Whereas girls were more likely to identify as bisexual, boys showed a stronger association between same-sex behavior and a bisexual identity. The pattern of association of age with sexual orientation differed between boys and girls. Our results highlight demographic differences between 2 sexual orientation dimensions, and their congruence, among 13- to 18-year-old adolescents. Future research is needed to better understand the implications of such differences, particularly in the realm of health and health disparities.

    Empirical research about late sexual debut and its consequences is limited, and further research is needed. To explore how students who had not had intercourse by the age of 18 years differed in terms of sociodemographic factors, physical and psychological health, sexual behavior, and history of sexual abuse from those who had. This is a cross-sectional survey involving 3,380 Swedish 18-year-olds. Descriptive analyses were used to investigate different types of sexual behavior. Ordinal data concerning alcohol consumption, self-esteem, sexual and physical abuse, parental relationships, sense of coherence, and health were analyzed, and multiple regression was carried out to identify the most important factors associated with no sexual debut. Just under a quarter of the adolescents had not had oral, anal, or vaginal sex by the age of 18 years, and they comprised the index group. They were characterized by being more likely to have caring fathers, parents born outside Europe, lower pornography consumption, lower alcohol and tobacco consumption, less antisocial behavior, and above all lower sexual desire (sometimes, adjusted odds ratio [aOR] 3.8; never/seldom, aOR 13.3) and fewer experiences of sexual abuse (aOR 25.5). Family structure and culture matters when it comes to the age of sexual debut. Adolescents with no sexual debut at 18 years of age seemed to live a more stable and cautious life than more sexual experienced peers, exemplified by fewer antisocial acts, less smoking and alcohol/drug consumption, less sexual desire, and less experience of sexual abuse.

    Full Text Available In various countries there are studies aimed at characterizing social representations on aging, but little is known about their relations with other representations. The present study proposes to characterize those relations through the notion of representational systems. An exploratory survey has been conducted with 151 Italian undergraduate students. They have completed evocation tasks about seven social objects linked to aging and also rated the distances among them. Distance ratings went through similarity analysis, while a prototypical analysis was carried out for aging and three objects: death, health and family. The results indicate possible content connections among representation elements and suggest a conjunction relationship between aging and family. The notion of representational systems opens possibilities for more refined representational characterizations.Há pesquisas em diversos países sobre representações sociais sobre envelhecimento, mas pouco se sabe sobre suas relações com outras representações. O presente estudo visa caracterizar essas relações através da noção de sistema representacional.

As avaliações de distância passaram por análise de similitude, enquanto que análises prototípicas foram realizadas para envelhecimento e três objetos: morte, saúde e família. Os resultados indicam possíveis conexões de conteúdos entre elementos das representações e sugerem uma relação de conjunção entre envelhecimento e família. A noção de sistemas representacionais abre possibilidades para o refinamento de caracterizações representacionais.

    Full Text Available Purpose. Effectiveness of nonpharmacological multicomponent prevention delivered by trained volunteers (medical and psychology students, targeted at delirium risk factors in geriatric inpatients, was assessed at an internal medicine ward in Poland. Patients and Methods. Participants were recruited to intervention and control groups at the internal medicine ward (inclusion criteria: age ≥ 75, acute medical condition, basic orientation, and logical contact on admission; exclusion criteria: life expectancy < 24 hours, surgical hospitalization, isolation due to infectious disease, and discharge to other medical wards. Every day trained volunteers delivered a multicomponent standardized intervention targeted at risk factors of in-hospital complications to the intervention group. The control group, selected using a retrospective individual matching strategy (1 : 1 ratio, regarding age, gender, and time of hospitalization, received standard care. Outcome Measures. Hospitalization time, deaths, falls, delirium episodes, and antipsychotic prescriptions were assessed retrospectively from medical documentation. Results. 130 patients (38.4% males participated in the study, with 65 in the intervention group. Antipsychotic medications were initiated less frequently in the intervention group compared to the control group. There was a trend towards a shorter hospitalization time and a not statistically significant decrease in deaths in the intervention group. Conclusion. Nonpharmacological multicomponent intervention targeted at delirium risk factors effectively reduced length of hospitalization and need for initiating antipsychotic treatment in elderly patients at the internal medicine ward.

    Full Text Available Introduction: Obesity may be a risk factor for mineralisation and bone structure disorders, contrary to a common belief in its protective effects on bone tissue. Aim: The aim of the study was to assess the relationship between selected risk factors and obesity indicators and bone mass in obese children. Material and methods: The study included 80 children aged between 7 and 10 years with excessive body weight (60 obese and 20 overweight; the reference group included 37 children with body weight appropriate for height. All patients underwent physical examination with anthropometric measurements. Parents were asked to complete a questionnaire. The average daily intake of selected nutrients was analysed using Dieta 2 software package. Densitometry (dual-energy X-ray absorptiometry, DXA was performed in all children to evaluate bone mass. Results: Obese and overweight children had statistically significantly higher total body BMD and total body BMD Z-score compared to control group. Most DXA parameters (except from volumetric bone mineral density were positively correlated with body weight, height and waist circumference. A significant positive correlation was found between physical activity and total body BMD. There was a negative correlation between the average daily intake of proteins, carbohydrates, magnesium and phosphorus in obese children and most DXA parameters (p < 0.05. Conclusions: Bone mass in obese children is positively affected by somatic features (body weight, height, waist circumference and body composition and physical activity, and negatively affected by increased intake of proteins, carbohydrates, phosphorus and magnesium. The calculated volumetric mineral bone density may reflect the actual bone mineral density and prevent DXA overestimation in obese children.

    Full Text Available OBJECTIVE: To assess the frequency of drug use among Brazilian college students and its relationship to gender and age. METHODS: A nationwide sample of 12,721 college students completed a questionnaire concerning the use of drugs and other behaviors. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST-WHO criteria were used to assess were used to assess hazardous drug use. A multivariate logistic regression model tested the associations of ASSIST-WHO scores with gender and age. The same analyses were carried out to measure drug use in the last 30 days. RESULTS: After controlling for other sociodemographic, academic and administrative variables, men were found to be more likely to use and engage in the hazardous use of anabolic androgenic steroids than women across all age ranges. Conversely, women older than 34 years of age were more likely to use and engage in the hazardous use of amphetamines. CONCLUSIONS: These findings are consistent with results that have been reported for the general Brazilian population. Therefore, these findings should be taken into consideration when developing strategies at the prevention of drug use and the early identification of drug abuse among college students.OBJETIVO: Avaliar a prevalência do uso de drogas entre universitários brasileiros, assim como sua relação com gênero e idade.

    Full Text Available Background: The concept of active ageing has been gaining prominence in the Nordic countries and beyond. This has been reflected in policy papers in Norway and other Nordic nations. Aims: The aim of this article is to analyse the topic of active ageing in five Norwegian White Papers (2002 to 2015 and discuss those policy documents in context of relevant research literature. Methods: A qualitative document analyses is employed focusing on how active ageing, and ageing in general, is described and which concepts are employed. No ethical approval was needed. Findings: The general theme of ageing and the specific theme of active ageing are increasingly prominent in the Norwegian White Papers studied. In all documents, some assumptions regarding ageing and active ageing seem implicit, such as independence being more important than (interdependence. ‘Productive’ activities like participation in working life are stressed, while others, like reading, watching TV or watching children playing in the street, are ignored. Conclusions: The policy documents demonstrate that the topic of active ageing is growing in importance. The documents increasingly seem to stress ‘productive’ activities – those related to working life, voluntary work or sports and physical training. They exclude activities that are meaningful for many older people, like watching their grandchildren play or reading books. Implications for practice: Practitioners in older people’s care could consider reflecting on: Government documents dealing with their own practice The prevalent concept of active ageing The trend of active ageing as a facilitating or hindering factor for good care work How present discourse on active ageing may influence their attitude towards frail older persons How they wish to relate to active ageing in their own practice

    The USNRC Office of Nuclear Regulatory Research has developed a program for nuclear plant aging research (NPAR) to achieve an understanding of nuclear plant aging, its potential effects on safety, and methods for its detection and mitigation, sufficient for addressing safety and regulatory issues and supporting regulatory decisions on issues. Specifically, the NRC has aggressive research and regulatory programs associated with aging effects on piping, steam generators, containments, structures, and electrical and mechanical systems and components. In addition to safety assessment for the original license period for nuclear power plants, this aging information will be extremely useful in providing technical bases for efficient and effective regulation associated with possible license extension. This paper discusses the major activities of USNRC sponsored aging research program and recommends an approach to manage and handle aging at nuclear power plants

Objective: To explore how students who had not had intercourse by the age of 18 years differed in terms of sociodemographic factors, physical and psychological health, sexual behavior, and history of sexual abuse from those who had. Materials and methods: This is a cross-sectional survey involving 3,380 Swedish 18-year-olds. Descriptive analyses were used to investigate different types of sexual behavior. Ordinal data concerning alcohol consumption, self-esteem, sexual and physical abuse, parental relationships, sense of coherence, and health were analyzed, and multiple regression was carried out to identify the most important factors associated with no sexual debut. Results: Just under a quarter of the adolescents had not had oral, anal, or vaginal sex by the age of 18 years, and they comprised the index group. They were characterized by being more likely to have caring fathers, parents born outside Europe, lower pornography consumption, lower alcohol and tobacco consumption, less antisocial behavior, and above all lower sexual desire (sometimes, adjusted odds ratio [aOR] 3.8; never/seldom, aOR 13.3 and fewer experiences of sexual abuse (aOR 25.5.

    Social influence occurs when an individual's thoughts or behaviours are affected by other people. There are significant age effects on susceptibility to social influence, typically a decline from childhood to adulthood. Most research has focused on negative aspects of social influence, such as peer influence on risky behaviour, particularly in adolescence. The current study investigated the impact of social influence on the reporting of prosocial behaviour (any act intended to help another person). In this study, 755 participants aged 8-59 completed a computerized task in which they rated how likely they would be to engage in a prosocial behaviour. Afterwards, they were told the average rating (in fact fictitious) that other participants had given to the same question, and then were asked to rate the same behaviour again. We found that participants' age affected the extent to which they were influenced by other people: children (8-11 years), young adolescents (12-14 years) and mid-adolescents (15-18 years) all significantly changed their ratings, while young adults (19-25 years) and adults (26-59 years) did not. Across the three youngest age groups, children showed the most susceptibility to prosocial influence, changing their reporting of prosocial behaviour the most. The study provides evidence that younger people's increased susceptibility to social influence can have positive outcomes. © 2018 The Authors.

    The idea of gerontogenes is in line with the evolutionary explanation of ageing as being an emergent phenomenon as a result of the imperfect maintenance and repair systems. Although evolutionary processes did not select for any specific ageing genes that restrict and determine the lifespan...... of an individual, the term ‘gerontogenes’ primarily refers to any genes that may seem to influence ageing and longevity, without being specifically selected for that role. Such genes can also be called ‘virtual gerontogenes’ by virtue of their indirect influence on the rate and process of ageing. More than 1000...... virtual gerontogenes have been associated with ageing and longevity in model organisms and humans. The ‘real’ genes, which do influence the essential lifespan of a species, and have been selected for in accordance with the evolutionary life history of the species, are known as the longevity assurance...

    Full Text Available The emerging concept of successful aging is based on evidence that in healthy individual when they get aged, there are  considerable variations in physiological functions alteration. Some people exhibiting greater, but others very few or no age related alteration. The first is called poor aging and the later is called successful pattern of aging (Lambert SW, 2008. Thus, in the simple words the successful aging concept is define as an opportunity of old people to stay  active and productive condition despite they get aged chronologically. Aging itself might be defined as the progressive accumulation of changes with time associated with or responsible for the ever-increasing susceptibility to disease and death which accompanies advancing age (Harman D, 1981. The time needed to accumulate changes is attributable to aging process. The marked emerging questions are how does aging happen and where does aging start? To answer these questions and because of the complexity of aging process, there are more than 300 aging theories have been proposed to explain how and where aging occured and started respectively. There are too many to enumerate theories and classification of aging process. In summary, all of these aging theories can be grouped into three clusters: 1. Genetics program theory, this theory suggests that aging is resulted from program directed by the genes; 2. Epigenetic theory, in these theory aging is resulted from environmental random events not determined by the genes; 3. Evolutionary theory, which propose that aging is a medium for disposal mortal soma in order to avoid competition between organism and their progeny for food and space, did not try to explain how aging occur, but possibly answer why aging occur (De la Fuente. 2009. Among the three groups of aging theories, the epigenetic theory is useful to explain and try to solve the enigma of aging which is prominently caused by internal and external environmental influences

    The aim of this study was to examine the relationship between self-reported leisure time physical inactivity frequency and sedentary behaviour and lifestyle correlates among school children in the Association of Southeast Asian Nations (ASEAN) region. The analysis included 30,284 school children aged 13-15 years from seven ASEAN countries that participated in the Global School-based Student Health Survey (GSHS) between 2007 and 2013. The measure asked about overall physical activity, walking or biking to school, and on time spent sitting. Overall, the prevalence of physical inactivity was 80.4%, ranging from 74.8% in Myanmar to 90.7% in Cambodia and sedentary behaviour 33.0%, ranging from 10.5% in Cambodia and Myanmar to 42.7% in Malaysia. In multivariate logistic regression, not walking or biking to school, not attending physical education classes, inadequate vegetable consumption and lack of protective factors (peer and parental or guardian support) were associated with physical inactivity, and older age (14 and 15 years old), coming from an upper middle income country, being overweight or obese, attending physical education classes, alcohol use, loneliness, peer support and lack of parental or guardian supervision were associated with sedentary behaviour. In boys, lower socioeconomic status (in the form of having experienced hunger) and coming from a low income or lower middle income country were additionally associated with physical inactivity, and in girls, higher socioeconomic status, not walking or biking to school and being bullied were additionally associated with sedentary behaviour. In conclusion, a very high prevalence of leisure physical inactivity and sedentary behaviour among school going adolescents in ASEAN was found and several factors identified that may inform physical activity promotion programmes in school-going adolescents in ASEAN.

    To determine the prevalence, magnitude and transient patterning of Relative Age Effects (RAEs) according to sex and stroke event across all age-groups at the Australian National age swimming Championships. Repeated years of cross-sectional participation data were examined. Participants were 6014 unique male (3185) and female (2829) swimmers (aged 12-18 years) who participated in Freestyle (50, 400m) and/or Breaststroke (100, 200m) at the National age swimming Championships between 2000-2014 (inclusive). RAE prevalence, magnitude and transience were determined using Chi-square tests and Cramer's V estimates for effect size. Odds Ratios (OR) and 95% Confidence Intervals (CI) examined relative age quartile discrepancies. These steps were applied across age-groups and according to sex and each stroke event. Consistent RAEs with large-medium effect sizes were evident for males at 12-15 years of age respectively, and with large-medium effects for females at 12-14 respectively across all four swimming strokes. RAE magnitude then consistently reduced with age across strokes (e.g., Q1 vs. Q4 OR range 16year old males=0.94-1.20; females=0.68-1.41). With few exceptions, by 15-16 years RAEs had typically dissipated; and by 17-18 years, descriptive and significant inverse RAEs emerged, reflecting overrepresentation of relatively younger swimmers. Performance advantages associated with relative age (and thereby likely growth and maturation) are transient. Greater consideration of transient performance and participation in athlete development systems is necessary. This may include revising the emphasis of sport programmes according to developmental stages and delaying forms of athlete selection to improve validity. Copyright © 2018 Sports Medicine Australia.

    The hypothesis that radiation may accelerate aging phenomenon has been studied extensively, using the population of A-bomb survivors. In this paper, non-specific radiation-induced premature aging is discussed with a review of the literature. Cardiac lipofuscin, papillary fibrosis, aortic extensibility, hexamine/collagen ratio in the skin and aorta, testicular changes, giant hepatic cell nucleus, and neurofibril changes have so far been studied pathologically in the context of A-bomb radiation. Only testicular sclerosis has been found to correlate with distance from the hypocenter. Suggestive correlation was found to exist between the hexamine/collagen ratio in the skin and aorta and A-bomb radiation. Grip strength and hearing ability were decreased in the group of 100 rad and the group of 50-99 rad, respectively. The other physiological data did not definitely correlate with A-bomb radiation. Laboratory data, including erythrocyte sedimentation rate, α and β globulin levels, phytohemagglutinin reaction, T cell counts, erythrocyte glycophorin-A, the incidence of cerebral stroke, ischemic heart disease, and cataract were age-dependent and correlated with A-bomb radiation. These findings indicated that the occurrence of arteriosclerosis-related diseases, changes in immunological competence, and some pathological and physiological findings altered with advancing age, suggesting the correlation with A-bomb radiation. In general, it cannot be concluded that there is a positive correlation between A-bomb radiation and the premature aging. (N.K.) 51 refs

    Living status (e.g., living with family or alone) may affect dietary habits. We compared nutritional adequacy according to living status and the frequency of eating out-of-home foods in young Japanese women. Female dietetic students (aged 18-20 years; n = 4,017) participated in a cross-sectional multicenter study, which was conducted in 85 dietetic schools in 35 of 47 prefectures in Japan. Habitual dietary intake was assessed with a validated diet history questionnaire. Nutritional adequacy was determined based on the Dietary Reference Intakes for Japanese, 2015, for two goals: preventing non-communicable chronic disease (a tentative dietary goal for preventing lifestyle-related diseases [DG] that tracks five nutrients) and avoiding insufficient intake of mainly vitamins and minerals (estimated average requirement [EAR] that tracks 14 nutrients). Women living with their family were less likely to meet DG nutrient levels, but more likely to meet EAR nutrient levels compared with those living alone. In contrast, women living alone had more inadequate nutrients with EAR and fewer nutrients with not-meeting DG than those living with families. A higher frequency of eating out-of-home was significantly associated with a higher prevalence of not-meeting DG nutrient levels only in the women living with their family. The prevalence of nutritional adequacy varied based on living status. In addition, women living with their family and those with a high frequency of eating out-of-home foods had the highest prevalence of not-meeting DG. Effective ways of improving dietary quality among young Japanese women differ by living status. Copyright © 2017 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

    This study sought to investigate the concept of wellness in high school students and in particular whether such variables as gender, age and life satisfaction impact on adolescent wellness. Data were collected from a sample of 240 high school students. Each of these subjects completed a basic demographic form along with the Adolescent Form of the Well[G1] ness Star Scale and Life Satisfaction Scale.  Data were analyzed with descriptive analysis, t-test and[G2] [G3]  oneway ANOVA. Results of these analyses failed to reveal significant differences between groups based on the variables of age, gender and life satisfaction about total wellness. The results suggested meaningful differences in social and physical subscales between genders. According to results, females have higher score on social subscale while males have higher score on physical subscale. The results also suggested a meaningful difference [G4] in social subscale among age groups. The finding showed that [G5] social subscale scores of students become lower with the increase in age[G6] . At the same time, no meaningful differences were found among different life satisfaction level in terms of subdimension of wellness. The findings were further examined in light of recent research and implications for counseling with adolescent s

Las actividades físicas de tiempo libre se consideran en la actualidad una necesidad para todos los seres humanos que posibilita calidad de vida y creación de un estilo de vida en la población, que benefician al hombre en su capacidad física, en la salud, en la economía, en los niveles de comunicación, en el desarrollo humano, tiene además un carácter preventivo de algunos de los males que aquejan a la sociedad. En los adolescentes se presenta un marcado interés en lo motor, por actividades que se presten al auto-examen, a la superación y a la competencia, así como se produce un afianzamiento de las posibilidades de participación en equipos deportivos. A través de la observación de las actividades física recreativas en el tiempo libre de los adolescentes, la realización de encuestas y entrevistas se comprobó que carecen de ser de la preferencia de ellos, son reiterativas y carecen de divulgación; Esto conlleva a que estos adolescentes emplee su tiempo libre en la realización de actividades que poco aportan a su educación y formación de su personalidad, por lo que proponemos un conjunto de actividades físico recreativas para contribuir a la ocupación del tiempo libre en los adolescentes de edades de 12-14 años de la circunscripción 184 del Consejo Popular Hermanos Cruz del municipio de Pinar del Río. Este trabajo será de utilidad y de servicio a los actores sociales de la circunscripción y adolescentes.

      Sometimes, a moment can announce the end of an age. The gold market is like that. Within two transaction days, the gold slumped by 13%and saw a 25%tumble from the high point in August 2011. According to the classic investment theory, a 20%-above decline means the shift from“a bull”to“a bear”market.   The super bear market of gold has lasted a dozen years. But the bull-to-bear shift was completed within only 20 minutes. Wall Street’s analysts and ordinary Chinese people had different understandings to the golden age.   Expecting a bear market, Wall Street continuously dumped gold, resulting in a diving of gold price. Seeing the benefits, leisure Chinese madams made a gold rush, causing a slight bounce of gold price. On April 23, renowned investment bank Goldman Sachs suspended the short sale. So,“Chinese aunts”beating back Wall Street’s analysts became the hottest topic online for the time being.   What are the decisive factors for the crash of gold price? Will the gold market complete a real bull-to-bear shift? Will the golden age of gold be farther or nearer?

    Full Text Available The present article deals with value orientations and their role in men’s lives, particularly, in young people’s lives. This notion was introduced by the American theoretical sociologist T. Parsons, one of the creators of modern theoretical sociology. The scientist made an attempt to construct the structural and analytical theory of social action, combining personal interests (needs and aims and situation, it takes place in. The issue of value orientations remains acute for psychology. Herein we have considered several most important works, relating to the considered issue. Age aspects of young people’s value orientations are of peculiar interest to us. When analyzing this phenomenon, one should take into consideration the psychological formations, inhere for a certain age. In fact every age has its unique structure, which may change when passing from one development stage to another. Basing on this fact, we’ve considered the values, depending on the age features of the youth, relying upon the works of the scientists, working with different categories of the youth, such as: teenagers, students, children of different nationalities. It is not surprising that most scientists have come to the conclusion that the chief role in value orientation belongs to a family, originates in relations with parents and teachers. The positive reinforcement to the future develops throughout life in accordance with a lifestyle of a family, society and political situation in a state.Life orientations as a type of value orientations show different types of young people’s preferences. Value structure of its consciousness has its own specific character, depending on the age peculiarities. The dynamics of the transition from one age to another is accompanied with the reappraisal of values, eventually, influencing the life strategy of the future generation

The most importantgoal in upper blepharoplasty for aging is correcting the drooping upper eyelid skin, and inthis process, the surgeon may or may not create a double eyelid fold. The pros and cons haveto be fully discussed with the patient, but the author personally prefers creating a doublefold unless the patient refuses, because it is efficient in correcting and preventing furtherdrooping of the skin. In most patients, the brow is elevated to compensate for the droopingeyelid, and when the drooping is corrected, brow ptosis may ensue. The surgeon has to preparefor these consequences before performing the procedure, and estimate the exact amountof skin to be excised. In the elderly, the skin and the orbicularis oculi muscle is thin, with adecreased amount of subcutaneous fat and retro-orbicularis oculi fat, and in most cases,excision of the skin alone is enough to correct the deformity. Removing large portions ofsoft tissue may also prolong the recovery period. Unlike younger patients, the lower skinflap should not be stretched too much in the elderly, as it may create an aggressive lookingappearance. A few wrinkles in the lower flap should remain untouched to create a naturallook. In this article, the author’s own methods of performing an aging blepharoplasty aredescribed specifically, with a step-by-step guide and surgical tips.

    The purpose of the study was to assess skeletal age using MP3 and hand-wrist radiographs and to find the correlation amongst the skeletal, dental and chronological ages. One hundred and sixty North-Indian healthy children in the age group 8-14 years, comprising equal number of males and females were included in the study. The children were radiographed for middle phalanx of third finger (MP3) and hand-wrist of the right hand and intra oral periapical X-ray for right permanent maxillary canine. Skeletal age was assessed from MP3 and hand-wrist radiographs according to the standards of Greulich and Pyle. The dental age was assessed from IOPA radiographs of right permanent maxillary canine based on Nolla's calcification stages. Skeletal age from MP3 and hand-wrist radiographs shows high correlation in all the age groups for both sexes. Females were advanced in skeletal maturation than males. Skeletal age showed high correlation with dental age in 12-14 years age group. Chronological age showed inconsistent correlation with dental and skeletal ages.

    At the Annual Meeting of the American Academy of Dermatology in 2016, I directed the symposium entitled ‘Aging Gracefully’ for the second time. The symposium’s primary learning objective was to give the audience a framework for managing aesthetic patients. In the last decade, there has been a significant increase in the options for and availability of noninvasive and minimally invasive rejuvenation. With that has been an associated surge in interest by physicians and patients. And, as the number of procedures across the globe increases, so too do the number of aesthetically poor outcomes. Most come from practitioners doing paint-by-numbers treatment. As experts in skin biology and treatment, dermatologists should practice the highest-level cosmetic as well as general dermatology. The faculty presented information to aid practitioners how best to approach patients and formulate a cosmetic plan. The faculty discussed important considerations based on patient gender, age, and skin type. Updated information on the science of cosmeceuticals and the benefits of early noninvasive intervention was presented as were next generation devices and alternatives to standard therapies. The faculty have kindly condensed their AAD presentations for this supplement. I thank L’Oréal and the Journal of Drugs in Dermatology for giving us the opportunity to present this information to a wider audience in this e-supplement. Heidi A.

    eficaces en sus empaques.OBJECTIVES: To evaluate the prevalence of smoking among Argentine adolescents and describe its usage, factors related to taking up the habit, and exposure to second-hand smoke in the home. METHODS: A cross-sectional study conducted through an anonymous survey of students 12-18 years of age in either the 8th grade of basic education or in the second course of high school or polytechnic school. The study took place in 2002 at 239 school within five urban centers of Argentina (Ciudad Autónoma de Buenos Aires, Partidos del Gran Buenos Aires, Gran Córdoba, Gran Mendoza, and Santa Fe. The random sample was stratified by socioeconomic level and rates were calculated according to an expanded sample composed of samplings from each stage. RESULTS: The survey was completed by 11 734 students (50.5% males; 44.1% were 12-14 years of age and 56.7% were 15-18 years. In all, 30.0% of the males and 35.0% of the females were smokers at the time of the survey (22.5% in the 12-14 year age group and 40.1% in the 15-18 group. The main reason given for taking up smoking was " to see what it was like" (43.7%; 44.3% of the students who smoked did so when they felt anxious. In all, 64.5% claimed they wanted to stop and 72.5% had attempted to quit, although fewer than 8% of the smokers had gotten any professional help to do so. The overwhelming majority considered it unhealthy to smoke tobacco (93.5% and be around second-hand smoke (89.6%. Only 30.4% felt they had not received enough information on detrimental effects of smoking. More than 70% of the adolescents were living with a smoker. CONCLUSIONS: There is a high rate of smoking among Argentine students, especially females. Policies must be established that will prevent smoking initiation in secondary school. Recommendations are to prohibit tobacco-product advertising and to require stronger health warnings labels.

    Full Text Available The purpose of this study was to (a identify potential benefits for students with disabilities taking part in a physical activity program with same-age typical peers on a Midwest university campus, and (b to determine if the program impacted the students with disabilities empowerment. Empowerment theory was used to determine how transition students’ attitudes change over the course of the semester while participating in a workout buddy program with same-age college peers. The program was structured to provide a sense of empowerment to students to make their own decisions and learn for themselves so they don’t feel a lack of power in their lives. This study implemented elements of a quantitative design but a majority utilized a qualitative design based on the assumptions of the Interpretivist paradigm. The quantitative design elements focused on the analysis of two questionnaires: Sports Questionnaire; and The Perceived Control Scale Questionnaire. The analysis of the focus group data revealed the following themes as positive effects of the intervention; positive effect on empowerment, how happy the program made the students, what benefits the students gained from the program, the student’s familiarity with university students, and the environment and lastly the students ability to ask for assistance when need. Findings from the study determined that the empowerment of the students with disabilities was impacted while participating in the program. In general, the findings of gaining empowerment were similar to previous studies in that students with disabilities are able to gain empowerment from participation in fitness and recreation programs. The researcher noted during focus groups that some of the BOBW students were not confident in starting conversations with their university. Although the BOBW students felt a sense of losing empowerment with this specific instance, there was an overall positive impact on the BOBW students

A 4-year observational study using a before-after-before (A-B-A design was carried out in an English state-funded high school. School start times were changed from 8:50 a.m. in study year 0, to 10 a.m. in years 1–2, and then back to 8:50 a.m. in year 3. Measures of student health (absence due to illness and academic performance (national examination results were used for all students. Implementing a 10 a.m. start saw a decrease in student illness after 2 years of over 50% (p < 0.0005 and effect size: Cohen's d = 1.07, and reverting to an 8:50 a.m. start reversed this improvement, leading to an increase of 30% in student illness (p < 0.0005 and Cohen's d = 0.47. The 10:00 a.m. start was associated with a 12% increase in the value-added number of students making good academic progress (in standard national examinations that was significant (<0.0005 and equivalent to 20% of the national benchmark. These results show that changing to a 10:00 a.m. high school start time can greatly reduce illness and improve academic performance. Implementing school start times later than 8:30 a.m., which may address the circadian delay in adolescents' sleep rhythms more effectively for evening chronotypes, appears to have few costs and substantial benefits.

An opinion survey was sent by e-mail to all undergraduate students of a university, registering gender, age, study years, study area, smoking behavior, motivation (reason for smoking), intention to quit and tobacco law perception. 1,008 (57% females) out of 11,679 surveys were answered back. Prevalence of active smoking among respondents was 36%, without association with gender, age or years of study. However, students from scientific areas had a lower prevalence. Seventy seven percent of smokers manifested the intention to quit the habit or have started quitting already. Ninety six percent were acquainted with the tobacco law and by 73% agreed with it. Smoking is highly prevalent among university students. It is necessary to develop strategies for smoking cessation within universities that may prevent or reduce tobacco smoking among students.

    The Multiverse education group at UC Berkeley's Space Sciences Lab created the NASA-funded "Five Stars Pathway" model in which five "generations" of girls and women engage in science together in an afterschool setting, with each generation representing one stage in the pathway of pursuing a career in science, technology, engineering, or math (STEM). The five stages are: elementary-age students, middle-school-age students, undergraduate-level college students, graduate-level college students and professional scientists. This model was field-tested at two Girls Inc. afterschool locations in the San Francisco Bay Area and distributed to Girls Inc. affiliates and other afterschool program coordinators nationwide. This presentation will explore some of the challenges and success of implementing a multigenerational STEM model as well as distributing the free curriculum for interested scientists and college students to use with afterschool programs.

    Characteristics of self-harm differ across ages, but there is little work identifying age-related differences in younger people. Young people entering adolescence face emotionally and developmentally different challenges to those entering adulthood. This study investigates how Emergency Department (ED) presentations and management of self-harm differ through adolescence and early adulthood. 3782 consecutive self-harm episodes involving 2559 people aged 12-25 years were identified from an existing database of Leeds ED attendances from 2004 to 2007. Odds ratios for each of four age bands were compared to the remaining young people. The female to male ratio was 6.3:1 at 12-14 years old, decreasing with successive age groups to 1.2:1 at 22-25 years old. Self-poisoning was commoner in those under 18 years old. 18-25 year olds were more likely to self-poison with prescribed medications, mixed overdoses, alcohol or recreational drugs. 18-25 year olds more often required medical treatment for the effects of the self-harm. 12-14 year olds were more often seen urgently by ED medical staff and offered high intensity mental health aftercare. Repetition of self-harm was commonest in 12-14 year olds, although multiple repetition of self-harm was commonest in 22-25 year olds. Data were not collected on whether the aftercare offered was received. The study sample included hospital attenders only. The large excess of females over males in young people's self-harm is only true at the younger age range. Older adolescents present with more severe acts of self-harm, yet receive the lowest intensity of assessment and after care. Copyright © 2016 Elsevier B.V. All rights reserved.

    Chinese international students have become an increasingly visible presence around the globe, and interest in these students has consequently increased among universities, researchers, and policy-makers, who often see international students as a source of increased soft power. This article...... questions the idea of Chinese international students as a soft-power tool. This is done through a critical discussion of the concept of soft power and the rather limited research on educational diplomacy, demonstrating that the analytical vagueness of the concept of soft power leads to an oversimplified...... understanding of the linkage between international students and soft power. In order to provide a more nuanced understanding of this linkage, the article examines the actual overseas experience of Chinese international students and argues that the linkage between international students and soft power is highly...

    2012-06-01

    The development of new technologies has provided medical education with the ability to enhance the student learning experience and meet the needs of changing curricula. Students quickly adapt to using multimedia learning resources, but these need to be well designed, learner-centred and interactive for students to become significantly engaged. One way to ensure that students become committed users and that resources become distinct elements of the learning cycle is to involve students in resource design and production. Such an approach enables resources to accommodate student needs and preferences, but also provides opportunities for them to develop their own teaching and training skills. The aim of the medical student research project was to design and produce an electronic resource that was focused on a particular anatomical region. The views of other medical students were used to decide what features were suitable for inclusion and the resulting package contained basic principles and clinical relevance, and used a variety of approaches such as images of cadaveric material, living anatomy movies and quizzes. The completed package was assessed using a survey matrix and found to compare well with commercially available products. Given the ever-diversifying arena of multimedia instruction and the ability of students to be fully conversant with technology, this project demonstrates that students are ideal participants and creators of multimedia resources. It is hoped that such an approach will help to further develop the skill base of students, but will also provide an avenue of developing packages that are student user friendly, and that are focused towards particular curricula requirements. © Blackwell Publishing Ltd 2012.

    The burnout syndrome is characterized by professional exhaustion and has been reported in college students. The aim of this study was to estimate the prevalence of Burnout Syndrome among dentistry students from a public university, and its relationship to socio-demographic characteristics. All students (n = 300) were invited to participate. We used the Maslach Burnout Inventory-Student Version (MBI-SS). We carried out an analysis of the MBI-SS' psychometric properties. Multivariate Analysis of Variance (MANOVA) was performed, followed by Analysis of Variance (ANOVA) and Tukey's post-hoc tests to compare the mean scores of burnout dimensions. Of the 235 participants, 72.8% were women and the mean age was 21.0 ± 1.8 years. The MBI-SS was reliable and valid. Of the students, 17.0% had Burnout Syndrome. There was a significant relation between Burnout Syndrome and a student's performance during the course (F = 4.433, p students most affected were those with poor performance, those who took medication because of studies, and those with thoughts of dropping the course. We concluded that the prevalence of the syndrome among dentistry students was high, with a significant relation between the syndrome and a student's academic performance, use of medication because of studies, and thoughts of dropping the course.

    1998-01-01

    To compare admission data and academic performances of medical students younger and older than 25, and to qualify older students' experiences and perceptions in medical school. The authors reviewed 1988-1991 data for applications to the McGill University Faculty of Medicine. Data included GPAs and MCAT scores, as well as ratings for reference letters, autobiographical statements, and interviews. For those same years, the authors measured students' academic performances in the preclinical and clinical years. The authors compared the data by students' age: "younger" students, aged 17 to 24; and "older" students, aged 25 and above. All enrolled students took the Derogatis Stress Profile, and the older students participated in focus groups. The older applicants had lower GPAs and MCAT scores, but higher interview and reference letter ratings. For older accepted students, basic science course scores were lower than those of younger students, but clinical scores did not differ significantly between the groups. The two groups had similar stress levels, although older students tested lower in driven behavior, relaxation potential, attitude posture, and hostility. In focus groups, the older students spoke of learning style differences, loss of social support, and loss of professional identity. Different scores in admission criteria suggest that McGill uses different standards to select older medical students. Older students admitted under different criteria, however, do just as well as do younger students by their clinical years. A broad-based study of admission criteria and outcomes for the older student population is warranted.

    The main objective of the study was to see whether medical students use more desirable approaches to studying than general education students. Survey method was used to collect data from both the medical students and the general education students. The survey of the medical students was carried out between January and March, 2012. The survey was administered to all the medical students present in lecture halls on day of data collection, while general education students were randomly selected from four subject areas at two universities. In total, 976 medical students and 912 general students participated in the study. Of the general students, 494(54%) were boys and 418(46%)were girls with an overall mean age of 20.53±1.77 years (range: 17-27 years). The medical students' perceptions of their learning environment and their learning preferences were broadly similar to that of general education students with the exception of workload. The medical students perceived the workload to be less appropriate (Mean = 2.06±0.72) than the students in general education (Mean = 2.84±0.90). The medical students were more likely to use the deep approach to studying (Mean = 3.66±0.59) than the students in general education (Mean = 3.16±0.91). The students in general education were slightly more likely to use the organized studying (Mean = 3.44±0.90) than the medical students (Mean =3.23±0.90). Both medical students and the students in general education tended to use the surface approaches along with other approaches to studying. There was not a great difference between the medical students and the students pursuing general education with regard to perceptions of the learning environment and approaches to learning.

    Full Text Available As the life expectancy continues to increase, the cognitive decline associated with Alzheimer’s disease (AD becomes a big major issue in the world. After cellular activation upon systemic inflammation, microglia, the resident immune cells in the brain, start to release proinflammatory mediators to trigger neuroinflammation. We have found that chronic systemic inflammatory challenges induce differential age-dependent microglial responses, which are in line with the impairment of learning and memory, even in middle-aged animals. We thus raise the concept of “microglia aging.” This concept is based on the fact that microglia are the key contributor to the acceleration of cognitive decline, which is the major sign of brain aging. On the other hand, inflammation induces oxidative stress and DNA damage, which leads to the overproduction of reactive oxygen species by the numerous types of cells, including macrophages and microglia. Oxidative stress-damaged cells successively produce larger amounts of inflammatory mediators to promote microglia aging. Nutrients are necessary for maintaining general health, including the health of brain. The intake of antioxidant nutrients reduces both systemic inflammation and neuroinflammation and thus reduces cognitive decline during aging. We herein review our microglia aging concept and discuss systemic inflammation and microglia aging. We propose that a nutritional approach to controlling microglia aging will open a new window for healthy brain aging.

    In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological foundation to assess the exhibit-student interaction and allowed analysis of the influence of the characteristics of students, exhibits, and interactions on students' learning. Eight students (ages 12ndash;13 years of age) with distinct sociological characteristics participated in the study. Several findings emerged from the results. First, the characteristics of the students, exhibits, and interactions appeared to influence student learning. Second, to most students, what they did interactively (procedures) seems not to have had any direct consequence on what they learned (concept understanding). Third, the data analysis suggest an important role for designers and teachers in overcoming the limitations of exhibit-student interaction.

    Universal vaccination programmes against Hepatitis B Virus (HBV) have significantly reduced the burden of the disease; nevertheless, HBV infection remains a relevant issue for high-risk subjects, such as healthcare workers (HCWs), who may potentially be exposed to blood or body fluids. Our study evaluates the long-term duration of the immunological memory of HBV vaccination 11-23 years after primary immunization by examining the response to booster doses in HCWs and students of health disciplines at Careggi Teaching Hospital in Florence (Italy). All participants (n = 2,203) had received a complete HBV immunization course in infancy or adolescence. Blood samples were collected to measure antibody levels against the HBV surface antigen (anti-HBs); an anti-HBs titre long-term anti-HBs titres compared to those in case of vaccination performed during adolescence (titre long incubation period of the disease allows the activation of immunologic memory mechanisms, which is also true in case of low anti-HBs level. In conclusion HCWs still represent a high-risk category; it is therefore, necessary to increase efforts to protect and vaccinate these subjects.

    Full Text Available While the last century was the century of world population growth, according to demographers, the XXI century will be century of population aging. Statistics undoubtedly show that number of elderly will continue it’s growth in the future. If old age is seen as period of life with reduced physical and mental capabilities and increased disability, and demographic aging as increase of dependent population, trends are quite disturbing, at least in certain societal segments. In developed countries, this population category is no longer treated as passive or as a "burden of society" and efforts are made for better social inclusion of older people. In contrast to growing interest in this phenomenon, the concepts that define the aging of the population remained stagnant. The aim of this paper is to introduce into domestic literature the term "prospective age" as a dynamic category which is more affected with socio-historical conditions, not only with biological as traditional definition of aging suggested. Papers written by Sanderson and Scherbov offer new methodological options for study of population aging, because it takes into account the biometric rather than chronological approach. Calculation of prospective years is a simple operation that requires pair of the same number of remained life expectancy from life tables for two different periods (the year of concern is index, and the one we are comparing with is standard year, so that phrase "40s is the new 30s" or "70s the new 60s" gets scientific foundation. Average remaining years of life represent a realistic indicator suggesting increased capacity, activity and vitality of individuals, which is due to accepted demographic parameters still considered old. „Prospective threshold“ is defined as the age when life expectancy falls below 15 years (it is subjective choice made by Sanderson and Scherbov, which is also used in this paper and during the elaboration of these ideas three demographic

    Full Text Available Concept mapping is an inquiry technique that provides students at all ages with opportunities to demonstrate learning through performance. A concept map refers to a graphic/visual representation of concepts with linking connections that show various relationships between concepts (Novak & Gowin, 1984. Assessment is an ongoing process integrated with instruction across subject areas. The National Council of Teachers of Mathematics (NCTM emphasizes that assessment should focus on both the enhancement of student learning as well as serve as a valuable tool for making instructional decisions (NCTM, 2000. Assessment activities can take on a variety of forms, one being performance tasks. In this manuscript, an explanation of concept mapping is provided for learners ages 3 – 12 along with several examples of concept maps for young learners, including examples from an assessment project in the subject area of mathematics. Also presented are the numerous benefits of the concept mapping technique for both students and teachers.

Creation of the stimuli involved fifty-one older adult and forty-four college student senders who lied authentically in that their lies were spontaneous in the service of protecting a research assistant. In the main study, seventy-seven older adult and eighty-four college raters attempted to detect lies in the older adult and college senders in three modalities: audio, visual, and audiovisual. Raters of both age groups were best at detecting lies in the audiovisual and worst in the visual modalities. Overall, college students were better detectors than older adults. There was an age-matching effect for college students but not for older adults. Older adult males were the hardest to detect. The older the adult was the worse the ability to detect deception.

    One of the many challenges that face middle grade students, parents, and teachers is the student's lack of ownership of their academic achievements. Student-led conferences are a unique way to engage the student and the parent in the academic progress. Parents and teachers discuss the student's attitude toward the work, the student's work ethic in…

    Full Text Available Grade inflation is a recognized problem in higher education in the United States. Age, gender, and ethnic differences in discrepancies between student reports of their expected grade in each course and their expectations for general university grading practices were explored in a survey of 166 (mostly female participants at a small upper-division university. Results revealed that while a small minority of students agreed that grading systems in college should only include A or B grades, a large majority of students expected A or B grades. Thus, student discrepancies between their expectations for grading systems and their expected class grades were in line with expectations that they should receive inflated grades. Results also revealed statistically significant age differences in grade expectation with students older than the age of 55 expecting lower grades relative to their younger counterparts.

    Suicide in elementary school-aged children is not well studied, despite a recent increase in the suicide rate among US black children. The objectives of this study were to describe characteristics and precipitating circumstances of suicide in elementary school-aged children relative to early adolescent decedents and identify potential within-group racial differences. We analyzed National Violent Death Reporting System (NVDRS) surveillance data capturing suicide deaths from 2003 to 2012 for 17 US states. Participants included all suicide decedents aged 5 to 14 years (N = 693). Age group comparisons (5-11 years and 12-14 years) were conducted by using the χ 2 test or Fisher's exact test, as appropriate. Compared with early adolescents who died by suicide, children who died by suicide were more commonly male, black, died by hanging/strangulation/suffocation, and died at home. Children who died by suicide more often experienced relationship problems with family members/friends (60.3% vs 46.0%; P = .02) and less often experienced boyfriend/girlfriend problems (0% vs 16.0%; P suicide note (7.7% vs 30.2%; P suicide decedents with known mental health problems (n = 210), childhood decedents more often experienced attention-deficit disorder with or without hyperactivity (59.3% vs 29.0%; P = .002) and less often experienced depression/dysthymia (33.3% vs 65.6%; P = .001) compared with early adolescent decedents. These findings raise questions about impulsive responding to psychosocial adversity in younger suicide decedents, and they suggest a need for both common and developmentally-specific suicide prevention strategies during the elementary school-aged and early adolescent years. Further research should investigate factors associated with the recent increase in suicide rates among black children. Copyright © 2016 by the American Academy of Pediatrics.

  13. GENDER CONFLICTS OF STUDENTS

    Full Text Available Actuality of work. Student age has the most favourable conditions for psychological, biological and social development; however, there are reasons why such natural advantages over other social groups can be completely or partially levelled. One of them is the presence of conflicts in the life of a student, a special group, among which there are women. The causes of the emergence of gender conflicts in individual social groups and the strategies for their solution have not been sufficiently explored and require further study and, therefore, are relevant. Purpose of the article is to investigate the causes of gender conflicts among students as a separate social group and to develop measures to address them and prevent them. Methodology. The research conducted in the work is based on the analysis and generalization of the causes of the emergence of gender conflicts among students, the identification of the main sources of information that form the consciousness of children and adolescents, and also influence their attitude to gender equality. Originality. The nature of gender conflicts has been quite effectively studied for a long time. However, the scope of research is limited to the most numerous social groups, such as the family, labour collective, political and public organizations, etc. Being a dynamic and socio-demographic formation, the students perform an important function in society – it takes a direct part in the transformation of all spheres of the life activity of the society. Based on the study of the objective conditions of the social environment with certain models of socialization that form the consciousness of students from early childhood, a three-component system of influence was first proposed, which is aimed at overcoming gender inequality and preventing gender conflicts among students. At the same time, the interaction of the components of the system will allow to minimize the gender inequality index in our country

    Intelligence is related to both height and body mass index (BMI) at various stages of life. Several studies have demonstrated longitudinal relationships between these measures, but none has established whether height and intelligence, or BMI and intelligence are linked from childhood through to older age. We assessed the relations between these measures over an interval of up to 67 years using data from the 36-Day Sample, an initially-representative sample of Scottish people born in 1936, assessed at age 11 years (N = 6,291) and again at 77-78 years (N = 722). This paper focuses on the 423 participants (6.7 % of the original sample) who provided relevant data in late adulthood. Height and intelligence were significantly positively associated in childhood (β = .23) and late adulthood (β = .21-.29). Longitudinal correlations also showed that childhood intelligence predicted late-adulthood height (β = .20), and childhood height predicted late-adulthood cognitive ability (β = .12-.14). We observed no significant relationship between BMI and intelligence either in childhood or in late adulthood, nor any longitudinal association between the two in this sample. Our results on height and intelligence are the first to demonstrate that their relationship spans almost seven decades, from childhood through to late adulthood, and they call for further investigation into the mechanisms underlying this lifelong association.

    An ageing population worldwide makes it increasingly important that health students understand issues that elderly people face and can provide empathic care to them. This teaching department in an isolated rural setting developed an interprofessional learning session to assist health students to understand issues of functional loss and social isolation that can affect elderly people. The Premature Ageing Unisex Leisure (PAUL) Suit(©) was developed as part of a 1-day learning session for undergraduate health students - including students of medicine, nursing and allied health - attending clinical placement in far-west New South Wales. The suit was developed locally and can be adjusted to simulate a wide range of functional losses in the wearer. Students undertake a range of daily tasks in the community while wearing the suit in the company of a student 'carer'. Over the past 4 years, approximately 140 students have participated in the simulation. Post-simulation evaluations report that students gain a greater understanding of some functional issues associated with ageing, and of the social isolation that can be associated with these. The experiential nature of the activity leads to some powerful insights. This activity is an innovative, experiential tool to deepen students understanding of issues related to ageing This activity is an innovative, experiential tool to deepen students understanding of issues relating to ageing. The interprofessional nature of the activity is an important factor in the success of the day, and produces a wide range of shared insights. The activity also enhances the partnerships between the university, the health service and the local community. Our experience supports the value of simulation in providing a deep learning opportunity in the area of ageing and disability. © 2015 John Wiley & Sons Ltd.

    In Turkey, which is a secular, democratic nation with a majority Muslim population, euthanasia is illegal and regarded as murder. Nurses and students can be faced with ethical dilemmas and a lack of a legal basis, with a conflict of religious beliefs and social and cultural values concerning euthanasia. The aim of this study was to investigate undergraduate nursing students' attitudes towards euthanasia. The study, which had a descriptive design, was conducted with 600 students. The 1st, 2nd, 3rd, and 4th year nursing students at a school of nursing were contacted in May 2009, and 383 students (63.8% of the study population of a total of 600 students) gave informed consent. Two tools were used in accordance with questionnaire preparation rules. The majority of students were female and single (96.9%), and their mean age was 21.3 ± 1.5 years. A majority (78.9%) stated they had received no training course/education on the concept of euthanasia. Nearly one-third (32.4%) of the students were against euthanasia; 14.3% of the students in the study agreed that if their relatives had an irreversible, lethal condition, passive euthanasia could be performed. In addition, 24.8% of the students agreed that if they themselves had an irreversible, lethal condition, passive euthanasia could be performed. Less than half (42.5%) of the students thought that discussions about euthanasia could be useful. There was a significant relation between the study year and being against euthanasia (p euthanasia could be abused (p euthanasia was unethical (p euthanasia.

  12. Students' conceptions about force

    2005-01-01

    Students from a young age have developed in their own minds differing concepts of things such as all creatures having a soul. Also children see the environment and interpret what they see according to their own understanding and explanation. In particular, with regards to physics, things like light, heat, motion, structure of matter and energy are understood at the level of a child s comprehension. Most often the child s understanding varies quite differently from the actual true meaning. As a result the child is reluctant to accept any other explanation. In such situations the necessary difficulties must be tackled with care and caution pertinent to the individual. Studies at K.S.U University related to force and motion of various departments in the Faculty of Science and Letters have been investigated. After evaluations of all the findings a number of suggestions have been made to change student views and ideas

  17. The Aging Epigenome

    Booth, Lauren N.

    2016-01-01

    During aging, the mechanisms that normally maintain health and stress resistance strikingly decline, resulting in decrepitude, frailty, and ultimately death. Exactly when and how this decline occurs is unknown. Changes in transcriptional networks and chromatin state lie at the heart of age-dependent decline. These epigenomic changes are not only observed during aging but also profoundly affect cellular function and stress resistance, thereby contributing to the progression of aging. We propose that the dysregulation of transcriptional and chromatin networks is a crucial component of aging. Understanding age-dependent epigenomic changes will yield key insights into how aging begins and progresses and should lead to the development of new therapeutics that delay or even reverse aging and age-related diseases.

    Directory of Open Access Journals (Sweden)

    Sven Bocklandt

    Full Text Available From the moment of conception, we begin to age. A decay of cellular structures, gene regulation, and DNA sequence ages cells and organisms. DNA methylation patterns change with increasing age and contribute to age related disease. Here we identify 88 sites in or near 80 genes for which the degree of cytosine methylation is significantly correlated with age in saliva of 34 male identical twin pairs between 21 and 55 years of age. Furthermore, we validated sites in the promoters of three genes and replicated our results in a general population sample of 31 males and 29 females between 18 and 70 years of age. The methylation of three sites--in the promoters of the EDARADD, TOM1L1, and NPTX2 genes--is linear with age over a range of five decades. Using just two cytosines from these loci, we built a regression model that explained 73% of the variance in age, and is able to predict the age of an individual with an average accuracy of 5.2 years. In forensic science, such a model could estimate the age of a person, based on a biological sample alone. Furthermore, a measurement of relevant sites in the genome could be a tool in routine medical screening to predict the risk of age-related diseases and to tailor interventions based on the epigenetic bio-age instead of the chronological age.
