    Full Text Available A distinctive feature of patients with ankylosing spondylitis is the formation of hip ankylosis in an extremely unfavorable functional position combined with upset of sagittal balance of the body along with a thoracolumbar kyphosis. Treatment of these patients poses considerable technical difficulties and is often associated with complications. The authors report a clinical case of a female 40 years old patient with confirmed rhizomelic spondylitis. The patient mainly complained of fixed malposition of the right lower extremity (hip ankylosis in extreme 1450 flexion and 1500 abduction combined with a severe fixed spine deformity (thoracic kyphosis 920, lumbar lordosis 170. Considering significant sagittal balance disorder it was decided to go for a two-stage procedure. Total hip arthroplasty of the right joint was performed at the first stage. At the second stage the authors corrected thoracolumbar spinal deformity by Th12 (type PSO 4 and L2 (type PSO 3 wedge resections and converging resected vertebral bodies by a multilevel fixation system with transpedicular support elements. The interval between the stages was 11 months. Two-stage treatment of this patient al-lowed to avoid adverse postoperative complications and to achieve a significant functional improvement in one year after treatment started. The sum of points before and after the treat-ment amounted respectively to 46 and 79 on Harris Hip Score, 17 and 38 points on Oxford Hip Score (OHS. To summarize, comprehensive treatment with planning of all subsequent steps prior to hip replacement is the method of choice for avoidance of postoperative complications in patients with ankylosing spondylitis accompanied by a significant upset of sagittal balance.

    To examine clinical and functional correlates of self-reported difficulty in climbing up or climbing down stairs in older adults. Cross-sectional survey. Community sample. Older adults (N=310; mean age, 79.7 y; 62% women), without disability or dementia. Not applicable. Clinical and functional status as well as activity limitations (able to perform activities of daily living [ADLs] with some difficulty). Of the 310 subjects, 140 reported difficulties in climbing up and 83 in climbing down stairs (59 both). Self-reported difficulty in climbing up stairs was associated with hypertension, arthritis, and depressive symptoms. Difficulty in climbing up stairs was also associated with poor balance and grip strength as well as neurologic gait abnormalities. Subjects with difficulty climbing down stairs had more falls. Both activities were associated with leg claudication, fear of falling, non-neurologic gait abnormalities, and slow gait. Examined individually, self-reported difficulty climbing down stairs captured a wider spectrum of ADL limitations than climbing up stairs. However, combined difficulty in both phases of stair climbing had a stronger association with activity limitations (vs no difficulty; odds ratio, 6.58; 95% confidence interval, 3.35-12.91) than difficulty in any one phase alone. Self-reported difficulty in climbing up and down stairs revealed commonalities as well as differences in related clinical correlates. Difficulty in both climbing up and down stairs should be separately assessed to better capture clinical and functional status in older adults.

    Students in middle school tend to display emotional and behavioural difficulties (EBDs) compared to other forms of psychopathology. Early identification of EBDs is therefore a priority in order to prevent the chronic co-morbidity with other forms of psychopathology which may affect students' academic achievement. Assessment of EBDs has been traditionally undertaken via proxy reporting; but psychometrically rigorous instruments are needed so that children and adolescents can report on their own emotions and behaviours. Such need increases in the Omani context given the lack of EBDs adequate assessment instruments. In the current study the factor structure of the Arabic self-report version of the Strengths and Difficulties Questionnaire (A-SDQ) was examined in a sample of 815 middle school students (mean age=14 years). The study tested the SDQ original five-factor model which received considerable empirical support. Responses on the A-SDQ were compared to responses obtained via proxy reports from teachers and parents through confirmatory factor analyses (CFAs). Results showed a reasonable fit for the three informant forms. Nevertheless, there were differences in item loadings across the three informant forms. Additionally, participants' self-report responses were tested for invariance across gender. CFAs provided support to the invariance hypothesis for item loadings, indicating that the items were similarly valid indices of the five factors for males and females. Factor correlations, factor variances and item residuals were not invariant across gender.

    Insulinomas are functional neuroendocrine pancreatic tumors rarely encountered in pediatric pathology. Insulinomas are usually solitary and sporadic, but may occur in association with multiple endocrine neoplasia type 1. Whipple's triad-hypoglycemia, simultaneous compatible adrenergic and/or neurological signs, and relief of symptoms upon the administration of glucose-remains the fundamental diagnostic tool. We report a case of insulinoma in an 11-year-old boy with malnutrition and mild psychic retardation. History revealed neuroglycopenic symptoms associated with hypoglycemia that returned to normal values after glucose intravenous infusion; before admission in our unit, the levels of circulating insulin, as well as the abdominal ultrasound and abdominal computed tomography scan, were reported within normal range. During hospitalization in our service, the glycemic curves showed recurring low values associated with low glycated hemoglobin, positive fasting test, and elevated C-peptide. The pancreatic ultrasound was inconclusive, but the magnetic resonance imaging revealed a high signal focal area with a diameter of 1 cm, located in the tail of pancreas. Conventional enucleation of the lesion prompted a spectacular normalization of glucose metabolism and the alleviation of the main clinical symptoms. The child had a favorable evolution in the clinical follow-up, presenting with weight gain and progressive remission to complete disappearance of most symptoms-except for the mental impairments. Although in our case Whipple's triad was apparent from the beginning, the diagnosis was delayed due to the failure of conventional imaging methods in locating the tumor. Weight loss and mental impairment contributed to the diagnosis pitfalls. Pediatricians should be aware of confusing and nonspecific symptoms, especially when children with insulinoma present mental or neurological retardation. Despite the existence of medical regimens, surgery remains the gold standard for the

    Full Text Available Background and Objectives: People with Williams syndrome (WS have been reported by their carers to have problems with attention, anxiety and social relationships. People with WS have been shown to report their anxieties. This study extends our knowledge of how people with WS see themselves in terms of behaviour and social relationships. Methods: A survey using self and parent report forms of the Strengths and Difficulties Questionnaire. Results: Both parents and individuals with WS (N = 31 reported difficulties in emotional disorder and hyperactivity symptoms and strengths in prosocial behaviours such as altruism and empathy. They disagreed about peer problems. Conclusions: People with WS understand some but not all of their difficulties. In particular they fail to recognize their social difficulties which may lead them to be vulnerable to exploitation.

A prospective case-control pilot study. Twenty-two participants were recruited in the study: 10 patients with reported hearing difficulty, normal audiometry, and a clinical diagnosis of APD; and 12 normal age-matched controls with no reported hearing difficulty. All participants completed the validated Amsterdam Inventory for Auditory Disability questionnaire, a hyperacusis questionnaire, a speech in babble test, and a TEOAE suppression test using contralateral noise. Patients had significantly worse scores than controls in all domains of the Amsterdam Inventory questionnaire (with the exception of sound detection) and the hyperacusis questionnaire (P correction. Strong correlations were observed between self-reported symptoms of difficulty hearing speech in noise and speech in babble test results in the right ear (ρ = 0.624, P = .002), and between self-reported symptoms of hyperacusis and TEOAE suppression test results in the right ear (ρ = -0.597 P = .003). There was no significant correlation between the two tests. A strong correlation was observed between right ear speech in babble and patient-reported intelligibility of speech in noise, and right ear TEOAE suppression by contralateral noise and hyperacusis questionnaire.

    The parent-report Strengths and Difficulties Questionnaire (SDQ-P) is a widely used scale that assesses children's and adolescents' strengths and difficulties. The present study applied this scale to Italian adolescents and compared the current results with previous Chinese findings and the United Kingdom norm. Participants were 422 Italian parents and their adolescent children. Parents and adolescents answered the parent-report and the self-report SDQ, respectively. Results showed that the five-factor first-order model was better than other competing models. Cronbach's alpha of emotional problems, conduct problems, hyperactivity, peer problems, prosocial behavior, and total difficulties was .63, .52, .69, .51, .59, and .77 respectively for mother-report measure, and .67, .48, .67, .46, .55, and .79 respectively for father-report measure. Parent-adolescent agreements ranged from low to medium, whereas mother-father agreements were large. Parents did not rate boys and girls as well as early-adolescence and mid-adolescence differently. Italian parents rated their adolescent children to have lower levels of hyperactivity, peer problems, total difficulties, and higher levels of prosocial behavior than Chinese parents; and Italian mothers rated their adolescent children to have lower levels of hyperactivity than United Kingdom parents. In conclusion, the current findings suggest both strengths and inadequacies of the SDQ-P for Italian adolescents.

    Background There is an increased prevalence of reading and related difficulties in children of dyslexic parents. In order to understand the causes of these difficulties, it is important to quantify the risk factors passed from parents to their offspring. Method 417 adults completed a protocol comprising a 15-item questionnaire rating reading and related skills and a scale assessing ADHD symptoms; 344 completed reading, nonword reading and spelling tests. Results A confirmatory factor analysis with four factors (Reading, Word Finding, Attention and Hyperactivity) provided a reasonable fit to the data. The Reading Factor showed robust correlations with measured literacy skills. Adults who reported as dyslexic, or rated their reading difficulties as more severe, gained lower scores on objective measures of literacy skills. Although the sensitivity of the new scale was acceptable, it tended to miss some cases of low literacy. Conclusions Self-report scales of reading and of attention difficulties are useful for identifying adults with reading and attention difficulties which may confer risks on their children of related problems. It is important for research following children at family risk of dyslexia to be aware of these effects. Copyright © 2012 John Wiley & Sons, Ltd. PMID:22271419

    Full Text Available OBJECTIVE: To describe the degree of difficulty that HIV-infected patients have with therapy treatment. INTRODUCTION: Patients’ perceptions about their treatment are a determinant factor for improved adherence and a better quality of life. METHODS: Two cross-sectional analyses were conducted in public AIDS referral centers in Brazil among patients initiating treatment. Patients interviewed at baseline, after one month, and after seven months following the beginning of treatment were asked to classify and justify the degree of difficulty with treatment. Logistic regression was used for analysis. RESULTS: Among 406 patients initiating treatment, 350 (86.2% and 209 (51.5% returned for their first and third visits, respectively. Treatment perceptions ranged from medium to very difficult for 51.4% and 37.3% on the first and third visits, respectively. The main difficulties reported were adverse reactions to the medication and scheduling. A separate logistic regression indicated that the HIV-seropositive status disclosure, symptoms of anxiety, absence of psychotherapy, higher CD4+ cell count (> 200/mm³ and high (> 4 adverse reaction count reported were independently associated with the degree of difficulty in the first visit, while CDC clinical category A, pill burden (> 7 pills, use of other medications, high (> 4 adverse reaction count reported and low understanding of medical orientation showed independent association for the third visit. CONCLUSIONS: A significant level of difficulty was observed with treatment. Our analyses suggest the need for early assessment of difficulties with treatment, highlighting the importance of modifiable factors that may contribute to better adherence to the treatment protocol.

  1. Diagnosing companies in financial difficulty based on the auditor’s report

    Directory of Open Access Journals (Sweden)

    Robert Zenzerović

    2016-04-01

    Full Text Available The approach used in this paper expands on existing research that focuses on devising prediction models for companies experiencing financial difficulties and which in turn serves as a criteria-based diagnosis tool for distinguishing healthy companies from those facing seriously financial difficulties. It draws on auditors’ reports on company financial statements that emphasize a company’s ability to continue as a going concern as the main criterion used to distinguish companies experiencing financial difficulties from companies that are not. Two closely-related hypotheses were tested in this paper. First, the authors tested the hypothesis that an auditor’s report accompanied by an explanatory paragraph pointing out issues associated with the going concern assumption is the proper criterion for differentiating companies experiencing financial difficulties from those that are not. Second, the central assumption that is tested relates to a combination of financial ratios whereby authors presume that an appropriate combination of financial ratios is a good analytical tool for distinguishing companies experiencing serious financial difficulties from those that are not. Research results conducted among 191 companies listed on the Zagreb Stock Exchange confirm both hypotheses. The LRA model – a diagnosis tool for identifying companies with financial problems, was also derived using logistic regression analysis. The statistical adequacy and quality of the model was tested using measures like Nagelkerke R2, type 1 and type 2 errors that appear when calculating the classification ability of the model. All measures indicated that model was statistically sufficient and validated its use as a diagnosis tool in recognizing the companies facing financial difficulties.

Cross-sectional probability sample. Chicago, IL. There were 2,983 black, Hispanic, and white adults. Outcomes included self-reported sleep duration and difficulties. Discrimination, including racial and nonracial everyday and major experiences of discrimination, workplace harassment and incivilities, and other stressors were assessed via questionnaire. In models adjusted for sociodemographic characteristics, greater exposure to racial (β = -0.14)) and nonracial (β = -0.08) everyday discrimination, major experiences of discrimination attributed to race/ethnicity (β = -0.17), and workplace harassment and incivilities (β = -0.14) were associated with shorter sleep (P discrimination attributed to race/ethnicity and sleep duration (β = -0.09, P Racial (β = 0.04) and non-racial (β = 0.05) everyday discrimination and racial (β = 0.04) and nonracial (β = 0.04) major experiences of discrimination, and workplace harassment and incivilities (β = 0.04) were also associated with more (log) sleep difficulties, and associations between racial and nonracial everyday discrimination and sleep difficulties remained after adjustment for other stressors (P Racial/ethnic differences in sleep duration and difficulties were not significant after adjustment for discrimination (P > 0.05). Discrimination was associated with shorter sleep and more sleep difficulties, independent of socioeconomic status and other stressors, and may account for some of the racial/ethnic differences in sleep.

    1996-03-13

    This work explores the hypothesis that Service Difficulty Reports (SDR - primarily inspection reports) are related to Accident Incident Data System (AIDS - reports primarily compiled from National Transportation Safety Board (NTSB) accident investigations). This work sought and found relations between equipment operability reported in the SDR and aviation safety reported in AIDS. Equipment is not the only factor in aviation accidents, but it is the factor reported in the SDR. Two approaches to risk analysis were used: (1) The conventional method, in which reporting frequencies are taken from a data base (SDR), and used with an aircraft reliability block diagram model of the critical systems to predict aircraft failure, and (2) Shape analysis that uses the magnitude and shape of the SDR distribution compared with the AIDS distribution to predict aircraft failure.

    Delayed revelation of congenital diaphragmatic hernias (CDH) is not uncommon and can represent 5-30% of total CDHs. Time before diagnosis may be prolonged, sometimes to the adult period. Respiratory and gastrointestinal symptoms are frequent but not specific. The clinical presentation of delayed CDH may thus mislead the practitioner. Diagnosis can be approached and/or confirmed by plain radiography. Outcome is usually favorable after surgery. We report two cases of delayed CDH and we discuss the difficulty of diagnosis.

    Full Text Available The aim of the present study was to investigate the epidemiology of psychological problems in adolescents in five provinces of Tehran, Khorasan Razavi, Isfahan, East Azerbaijan and Fars in Iran.In the present cross-sectional and descriptive - analytical study, 5171 adolescents aged 12 to 17 years were selected through multistage cluster sampling method from Tehran, Isfahan, Fars, Khorasan Razavi and East Azarbaijan provinces. The self-report form of Strengths and Difficulties Questionnaire (SDQ was used to obtain the demographic data of each adolescent. Descriptive analysis and 95% confidence interval were used to investigate the relationship between scores of the SDQ questionnaire and demographic factors.Based on the results, the highest prevalence of psychological problems in the five provinces was related to conduct problems (24%, and the lowest prevalence was related to social problems (5.76%. Also, comparison of 95% confidence interval of prevalence of psychological problems between the two genders suggested a significant difference only in emotional problems of the self-report version of the SDQ between the two genders. The result revealed no significant difference in the psychological problems of the self-report version of the SDQ between the two age's groups and between the middle and high school graduates (p≤0.05. Among the 5 provinces, Fars allocated the highest rates of conduct problems (28.4, hyperactivity problems (21.5% and overall criterion problems (17.3%; Esfahan had the highest rates of emotional problems (9.1% and problems with peers (8.1%; and Khorasan Razavi had the highest rates of social problems (7.6%.In this study, the highest prevalence of psychological problems in the five provinces was related to conduct problems, and the lowest prevalence was related to social problems. It was determined that girls have more emotional problems than boys. Also, no significant difference was found in the psychological problems of 12

    The utility of parent and teacher reports for screening 3 types of bilingual preschoolers (English-first language [L1]/Mandarin-second language[L2], Mandarin-L1/English-L2, or Malay-L1/English-L2) for language difficulty was investigated in Singapore with reference to measures of reliability, validity, sensitivity, and specificity in an English-medium kindergarten setting. The index tests were teachers' ratings of the English language ability of 5-year-olds (N = 85) on the Bilingual Language Assessment Battery (BLAB): Preschool Teacher Report (Pua, Lee, & Rickard Liow, 2013) and parents' ratings of their child's home language ability (N = 78 English-L1, Mandarin-L1, or Malay-L1) on the BLAB: Preschool Parent Report (Pua, Lee, & Rickard Liow, 2013). The reference standards were objective measures of single-word receptive vocabulary (80 items) and expressive vocabulary (140 items) in the child's L1 and L2, as proxies for language ability. BLAB Teacher Reports for the English receptive and expressive subscales showed concurrent validity for all 3 bilingual groups, as well as generally high sensitivity and specificity. In contrast, BLAB Parent Reports for L1 receptive ability failed to show significant correlations with the objective measures of receptive vocabulary. Subjective teacher ratings may be an effective method of screening bilingual preschoolers for language difficulty, thereby prompting referral to clinicians.

    A synthetic model of scheduled-commercial U.S. aviation fatalities was constructed from linear combinations of the time-spectra of critical systems reporting using 5.5 years of Service Difficulty Reports (SDR){sup 2} and Accident Incident Data System (AIDS) records{sup 3}. This model, used to predict near-future trends in aviation accidents, was tested by using the first 36 months of data to construct the synthetic model which was used to predict fatalities during the following eight months. These predictions were tested by comparison with the fatality data. A reliability block diagram (RBD) and third-order extrapolations also were used as predictive models and compared with actuality. The synthetic model was the best predictor because of its use of systems data. Other results of the study are a database of service difficulties for major aviation systems, and a rank ordering of systems according to their contribution to the synthesis. 4 refs., 8 figs., 3 tabs.

    Full Text Available Within the context of a turbulent economic environment with impact on the vulnerability of the public sector entities, the stakeholders’ needs of information are focussed on the assessment of liquidities and their solvency, on the sustenability of service offerring, as well as on the capacity of the entities to answer a dynamic environment in terms of cost, quality and continuity. In this respect, the current study has as objective to identify the difficulties of reporting the financial position into the public sector in Romania. In order to reach the proposed objective, an interpretative research methodology was used. The results of this study has pointed out that the prevalence of divergences between the national view versus IPSAS in terms of reporting the financial position into the public sector limits the informational value and its relevance both for the management of the entities and their stakeholders.

    Clinicians encounter patients who report experiencing hearing difficulty (HD) even when audiometric thresholds fall within normal limits. When there is no evidence of audiometric hearing loss, it generates debate over possible biomedical and psychosocial etiologies. It is possible that self-reported HDs relate to variables within and/or outside the scope of audiology. The purpose of this study is to identify how often, on a population basis, people with normal audiometric thresholds self-report HD and to identify factors associated with such HDs. This was a cross-sectional investigation of participants in the Beaver Dam Offspring Study. HD was defined as a self-reported HD on a four-item scale despite having pure-tone audiometric thresholds within normal limits (hearing assessments, relevant factors such as sociodemographic and lifestyle factors, environmental exposures, medical history, health-related quality of life, and symptoms of neurological disorders were also examined as possible risk factors. The Center for Epidemiological Studies-Depression was used to probe symptoms associated with depression, and the Medical Outcomes Study Short-Form 36 mental score was used to quantify psychological stress and social and role disability due to emotional problems. The Visual Function Questionnaire-25 and contrast sensitivity test were used to query vision difficulties. Of the 2783 participants, 686 participants had normal audiometric thresholds. An additional grouping variable was created based on the available scores of HD (four self-report questions), which reduced the total dataset to n = 682 (age range, 21-67 years). The percentage of individuals with normal audiometric thresholds who self-reported HD was 12.0% (82 of 682). The prevalence in the entire cohort was therefore 2.9% (82 of 2783). Performance on audiological tests (distortion product otoacoustic emissions and word-recognition tests) did not differ between the group self-reporting HD and the group

    Despite documented effects on fetal brain development, little is currently known about the relationship between maternal pregnancy hypertension and child neuropsychological outcomes. This brief report examined the association between maternal hypertension during pregnancy and children's social cognition and executive functioning when children were 18 months, 3 years, and 4.5 years. A community sample of 501 families (23 hypertensive mothers; 478 nonhypertensive) was recruited when children were newborns. Social cognition (including theory of mind [ToM]) and executive functioning (EF) were measured using a battery of age-appropriate standardized and/or observational tasks. Information on pregnancy and prenatal factors were measured via maternal report when children were newborns. After controlling for prenatal and demographic covariates, the presence of hypertension difficulties during pregnancy was associated with all measures of social cognition, ToM, and EF. A secondary analysis comparing the hypertension group (n = 23) to a nonhypertensive matched control group (n = 23) supported the effect of pregnancy hypertension on children's social-cognitive and EF development. Future studies using obstetrical records are encouraged based on these preliminary findings.

  13. The Positive Facet of Self-compassion Predicts Self-reported Use of and Attitudes toward Desirable Difficulties in Learning

    Full Text Available Previous research found that introducing difficulties and challenges during learning has desirable outcomes. With the present work, we investigated the question how the use of and the attitudes toward such learning strategies (so-called desirable difficulties are related to self-compassion, a concept that describes the tendency to be understanding and kind to oneself when confronted with negative experiences. Evidence suggests self-compassion to be linked to less fear of failing, and further to higher control beliefs and mastery goals in learning. Given that applying desirable difficulties in self-regulated learning implies increased challenges, and further, a higher likelihood to experience a feeling of failing, we expected that the use of desirable difficulties increases with levels of self-compassion. We tested this hypothesis in an online study (N = 136 in which self-compassion and the self-reported use of and attitudes toward strategies of desirable difficulties were assessed via respective questionnaires. Results of a correlation analysis yielded first evidence for our idea. Decomposing self-compassion into a positive and a negative facet showed that the positive, but not the negative, facet is positively correlated with attitudes toward and the use of desirable difficulties. Additionally, a regression analysis showed that the positive but not the negative facet predicted attitudes toward and use of desirable difficulties, when entering both facets simultaneously as predictors. Practical implications for learners are discussed.

    A previous study reported that children with poor motor skills, classified as having motor difficulties (MD) or Developmental Coordination Disorder (DCD), produced more errors in a motor response inhibition task compared to typically developing (TD) children but did not differ in verbal inhibition errors. The present study investigated whether these groups differed in the length of time they took to respond in order to achieve these levels of accuracy, and whether any differences in response speed could be explained by generally slow information processing in children with poor motor skills. Timing data from the Verbal Inhibition Motor Inhibition test were analyzed to identify differences in performance between the groups on verbal and motor inhibition, as well as on processing speed measures from standardized batteries. Although children with MD and DCD produced more errors in the motor inhibition task than TD children, the current analyses found that they did not take longer to complete the task. Children with DCD were slower at inhibiting verbal responses than TD children, while the MD group seemed to perform at an intermediate level between the other groups in terms of verbal inhibition speed. Slow processing speed did not account for these group differences. Results extended previous research into response inhibition in children with poor motor skills by explicitly comparing motor and verbal responses, and suggesting that slow performance, even when accurate, may be attributable to an inefficient way of inhibiting responses, rather than slow information processing speed per se.

    Full Text Available Background: Oral health has strong biological, psychological, and social projections, which influence the quality of life. Thus, developing a common vision and a comprehensive approach to address children′s social, emotional, and behavioral health needs is an integral part of the child and adolescent′s overall health. Aim: To assess and compare the behavior and emotional difficulties among 15-year-olds and to correlate it with their dentition status based on gender. Study Settings and Design: A cross-sectional questionnaire study among 15-year-old schoolgoing children in six private schools in Dilsukhnagar, Hyderabad, India. Materials and Methods: The behavior and emotional difficulties were assessed using self-reported Strengths and Difficulties Questionnaire (SDQ. The dentition status was recorded by the criteria given by the World Health Organization (WHO in the Basic Oral Health Survey Assessment Form (1997. Statistical Analysis: Independent Student′s t-test was used for comparison among the variables. Correlation between scales of SDQ and dentition status was done using Karl Pearson′s correlation coefficient method. Results: Girls reported more emotional problems and good prosocial behavior and males had more conduct problems, hyperactivity, peer problems, and total difficulty problems. Total decayed-missing-filled teeth (DMFT and decayed component were significantly and positively correlated with total difficulty, emotional symptom, and conduct problems scale while missing component was correlated with the hyperactivity scale and filled component with prosocial behavior. Conclusion: DMFT and its components showed an association with all scales of SDQ except for peer problem scale. Thus, the oral health of children was significantly influenced by behavioral and emotional difficulties; so, changes in the mental health status will affect the oral health of children.

    Full Text Available Osteomas are benign bone tumors which arise from the cortex or medulla of craniofacial and jaw bones. They are usually asymptomatic or present as slow-growing painless masses. Larger lesions may present with aesthetic (facial asymmetry and functional disturbances (jaw deviation, difficulty in breathing, pain, and sensory deficits. This paper highlights a case of solitary peripheral osteoma composed of a compact bony mass arising from the lower border of the mandible in an adult female patient. The lesion presented with discomfort during deglutition, which was attributed to impingement of muscles of the oral cavity floor, including the anterior belly of digastric muscle.

    Full Text Available Multimorbidity receives increasing scientific attention. So does the detrimental health impact of adverse childhood experiences (ACE. Aetiological pathways from ACE to complex disease burdens are under investigation. In this context, the concept of allostatic overload is relevant, denoting the link between chronic detrimental stress, widespread biological perturbations and disease development. This study aimed to explore associations between self-reported childhood quality, biological perturbations and multimorbidity in adulthood.We included 37 612 participants, 30-69 years, from the Nord-Trøndelag Health Study, HUNT3 (2006-8. Twenty one chronic diseases, twelve biological parameters associated with allostatic load and four behavioural factors were analysed. Participants were categorised according to the self-reported quality of their childhood, as reflected in one question, alternatives ranging from 'very good' to 'very difficult'. The association between childhood quality, behavioural patterns, allostatic load and multimorbidity was compared between groups.Overall, 85.4% of participants reported a 'good' or 'very good' childhood; 10.6% average, 3.3% 'difficult' and 0.8% 'very difficult'. Childhood difficulties were reported more often among women, smokers, individuals with sleep problems, less physical activity and lower education. In total, 44.8% of participants with a very good childhood had multimorbidity compared to 77.1% of those with a very difficult childhood (Odds ratio: 5.08; 95% CI: 3.63-7.11. Prevalences of individual diseases also differed significantly according to childhood quality; all but two (cancer and hypertension showed a significantly higher prevalence (p<0.05 as childhood was categorised as more difficult. Eight of the 12 allostatic parameters differed significantly between childhood groups.We found a general, graded association between self-reported childhood difficulties on the one hand and multimorbidity, individual

    Cameron and Cameron's reanalysis of published data in 2002 indicates children being raised in a home environment with at least one homosexual parent report some negative consequences. However, a closer look at the information presented suggests (especially in the absence of control groups) that the negative consequences documented do not constitute major psychological trauma. Rather, they are more in the nature of the teasing and bullying that plagues any child who comes from a home that may be atypical in any fashion.

    Angiosarcoma is a rare primary malignant mesenchymal tumor of the liver. The prognosis of hepatic angiosarcoma is poor with an average life expectancy of 6 months after diagnosis. Diagnosing hepatic angiosarcoma is challenging because of nondiagnostic liver biopsy or specious history and radiologic presentation. We report 2 cases with hepatic angiosarcoma which were diagnosed histopathologically in the native liver after liver transplant. One of 2 patients was lost to follow-up, and another patient died of relapsing hepatic angiosarcoma 18 months after the liver transplant.

    2011-01-01

    There are two types of vitamin D dependent rickets (VDDR) that cause rickets in children. Vitamin D dependent rickets type 1 (VDDR-I) is caused by an inborn error of vitamin D metabolism, which interferes with renal conversion of calcidiol (25OHD) to calcitriol (1,25(OH)2D) by the enzyme 1alpha-hydroxylase. Vitamin D dependent rickets type 2 (VDDR-II) is caused by a defect in the vitamin D receptor (VDR). We report cases of two African children affected by VDDR-I and VDDR-II, respectively. Establishing an early diagnosis of these genetic forms of rickets is challenging, especially in developing countries where nutritional rickets (NR) is the most common variety of the disease. A prompt diagnosis is necessary to initiate adequate treatment, resolve biochemical features and prevent complications, such as severe deformities that may require surgical intervention.

The frequency of each symptom domains according to Goodman's cutoff points and 90th percentile and the mean score in each subscale were determined.Results:The 90th percentile cutoff points were somewhat different from those of the previous reports. Using Goodman's cutoff points, the prevalence of symptom domains was relatively high. For example, 13.7 percent of the adolescents studied had total scores equal to 20 or more. There were significant correlations between different subscales and their constituting questions.Conclusion:Self-report form of SDQ is a valuable tool in the screening of adolescent psychopathologies. Frequency of majority of the symptom domains seems to be higher in the adolescents in Tehran urban areas.

    To provide estimates for the prevalence of parent-reported speech-language difficulties in U.S. children, and to describe the levels of health care access and material hardship in this population. We tabulated descriptive and bivariate statistics using cross-sectional data from the 2007 and 2011/2012 iterations of the National Survey of Children's Health, the 2005/2006 and 2009/2010 iterations of the National Survey of Children with Special Health Care Needs, and the 2004 and 2008 panels of the Survey of Income and Program Participation. Prevalence estimates ranged from 1.8% to 5.0%, with data from two of the three surveys preliminarily indicating increased prevalence in recent years. The largest health care challenge was in accessing care coordination, with 49%-56% of children with parent-reported speech-language difficulties lacking full access. Children with parent-reported speech-language difficulties were more likely than peers without any indications of speech-language difficulties to live in households experiencing each measured material hardship and participating in each measured public benefit program (e.g., 20%-22% experiencing food insecurity, compared to 11%-14% of their peers without any indications of speech-language difficulties). We found mixed preliminary evidence to suggest that the prevalence of parent-reported speech-language difficulties among children may be rising. These children face heightened levels of material hardship and barriers in accessing health care.

    A specific overlap between Asperger syndrome (AS) and nonverbal learning difficulties (NLD) has been proposed, based on the observation that, as a group, people with AS tend to have significantly higher verbal IQ (VIQ) than performance IQ (PIQ), one of the core features of NLD. The primary aim was to assess the longer term outcome of NLD--broken down into persistent and transient forms. The present study of 68 individuals was performed in the context of a larger prospective longitudinal study to late adolescence/early adult life of 100 boys with AS. Using self- and parent-report measures, we studied the longer term outcome of the NLD (defined as VIQ > PIQ by 15 points) as regards social communication, repetitive behaviour, attention, and executive function (EF) was studied. Three subgroups were identified: (1) Persistent NLD (P-NLD), (2) Childhood "only" NLD (CO-NLD) and (3) Never NLD (NO-NLD). The P-NLD group had the worst outcome overall. The CO-NLD group had better reported EF scores than the two other AS subgroups. There were no differences between the subgroups regarding social communication, repetitive behaviour, or attentional skills. Low PIQ increased the risk of ADHD symptoms. In the context of AS in males, P-NLD carries a relatively poor outcome, particularly with regard to self-reported EF. However, CO-NLD appears to entail a significantly better outcome. The results underscore the importance of analysing the cognitive profile both at diagnosis and after several years, so as to be able to formulate a realistic prognosis.

    Managing stairs is a challenging activity of daily living (ADL) for older people. This study aims to examine the association between visual impairment and difficulty in managing stairs among older people living alone and those living with others. A population-based cross sectional study was conducted in rural Malaysia from 2007 till 2008. Seven hundred and sixty five older people aged 60 years and over underwent eye examination for visual impairment. Visual acuity criteria were used to define visual impairment. Presenting visual acuity was assessed using a standard metric Snellen Chart of E type. Difficulty in managing stairs was measured according to a question drawn from the Barthel Index which asks "do you need help in climbing stairs". Overall, the prevalence of difficulty in managing stairs among older people in our population was 135 (18.3%, 95% CI 15.7-21.2). After adjusting for important confounders the odds ratio (OR) for visual impairment and difficulty in managing stairs among older people living alone was 5.04 (95% CI 2.27, 10.62). Among older people living with others, the adjusted OR for visual impairment and difficulty in managing stairs was 3.10 (95% CI 1.52, 6.80). In a sample of older people aged 60 years and over, those living alone with visual impairment had greater difficulty in managing stairs than those living with others. Identification of these groups of older people is useful for targeting interventions. Copyright © 2012 Elsevier Inc. All rights reserved.

  12. Resting Heart Rate Variability Predicts Self-Reported Difficulties in Emotion Regulation: A Focus on Emotional Clarity and Impulse Control

    Directory of Open Access Journals (Sweden)

    DeWayne P Williams

    2015-03-01

    Full Text Available The Model of Neurovisceral Integration suggests that vagally mediated heart rate variability (vmHRV represents a psychophysiological index of inhibitory control and thus, is associated with emotion regulation capacity. Over the past decade, growing empirical evidence supports this notion, showing that those with higher resting vmHRV can regulate and control negative emotions more adequately. However, to our knowledge, no study has previously examined how resting vmHRV may relate to everyday perceived difficulties in emotion regulation. The present study attempts to examine such relationship in 183 undergraduate students (98 female, 60 minority, mean Age = 19.34. Resting vmHRV was collected during a 5-minute resting baseline period, and everyday difficulties in emotion regulation were assessed using the Difficulties in Emotion Regulation Scale (DERS. Controlling for potential confounds (including both trait anxiety and rumination, results revealed a negative relationship between resting vmHRV and DERS such that lower resting vmHRV was associated with greater difficulties in emotional control, especially a lack of emotional clarity and impulse control, as indicated by the respective subscales of the DERS. These findings provide further evidence for the Neurovisceral Integration Model, suggesting that emotional control and autonomic regulation share neural networks within the brain. Moreover, the present study extends prior research by highlighting two distinct facets of emotion regulation (impulse control and emotional clarity that should be of particular interest when investigating the link between emotion regulation, resting vmHRV, and related health outcomes including morbidity and mortality.

    Abstract Background A prospective cohort study was set up to investigate a possible association between antibiotic prescribing and antibiotic resistance of E. coli urinary tract infection in the community. Participation of patients with urinary tract infection was obtained through an opt-out methodology. This short paper reports on the acceptability of the opt-out recruitment approach. Methods Participating practices (22) were requested to send a urine sample from all patients presenting with symptoms of urinary tract infection. Upon receipt of the sample in the laboratory, a letter explaining the study, an opt-out form and a freepost envelope were sent to all adult patients. A website with additional information and including an \\'opt-out\\' button was set up for the study. Results A total of 1362 urine samples were submitted by the 22 participating practices representing 1178 adult patients of whom 193 actively responded to the letter: 142 opted out by letter, 15 through the website, 2 by phone and 12 sent the letter back without indication, making a total of 171 patients or 14.5% opt-out; the remaining 22 patients (1.9%) explicitly opted in. The total group consisted of 80% women and the mean age was 50.9 years (sd 20.8). No significant differences were found between patients who participated and those who opted out in terms of age, gender or whether the urine sample was positive or not. Conclusions Overall the opt-out method was well received and participation in the study reached 85.5%. The low number of complaints (2) indicates that this is a generally acceptable method of patient recruitment. The 14.5% opt-out shows that it effectively empowers patients to decline participation. The similarity between patients opting out and the rest of the patients is reassuring for extrapolation of the results of the study.

    Background: Child and adolescent psychiatry has benefited from the application of self-report questionnaires because it is short, less costly and easy to apply. So we select the Strengths and Difficulties Questionnaire (SDQ) and evaluate the agreement between the self-report and parent report form. Materials and Methods: Subjects were 1934 Adolescents, 11-18 years old. After obtaining the samples consent, SDQ parent rated form and self-rated form were filled. The collected data were analyzed using the STATA statistical package version 9. Results: The adolescents obtained higher total difficulty scores than their parents, but it was not significant (P = 0.203). Boys had higher total difficulty scores than girls by parent informant (P = 0.001), but by self-report girls had higher total difficulty scores than boys (P = 0.42). 11-14 years had higher total difficulty scores by parent report than self-report (P = 0.42), but 15-18 years had higher total difficulty scores by self-report than parent report (P = 0.36). Conclusion: SDQ self-rating from adolescents may contribute better to the diagnostic process in the clinical setting. PMID:24250700

    Full Text Available Thirty-eight radiation safety reports for brachytherapy equipment were evaluated to determine the current status of brachytherapy units in Korea and to assess how radiation oncology departments in Korea complete radiation safety reports. The following data was collected: radiation safety report publication year, brachytherapy unit manufacturer, type and activity of the source that was used, affiliation of the drafter, exposure rate constant, the treatment time used to calculate workload and the HVL values used to calculate shielding design goal values. A significant number of the reports (47.4% included the personal information of the drafter. The treatment time estimates varied widely from 12 to 2,400 min/week. There was acceptable variation in the exposure rate constant values (ranging between 0.469 and 0.592 (R-m2/Ci·hr, as well as in the HVLs of concrete, steel and lead for Iridium-192 sources that were used to calculate shielding design goal values. There is a need for standard guidelines for completing radiation safety reports that realistically reflect the current clinical situation of radiation oncology departments in Korea. The present study may be useful for formulating these guidelines.

    Four cases of idiopathic chondrolysis of the hip in three white girls and one Maori girl are reported. The authors stress the causes why a disease with characteristic clinical and radiographic appearances and normal biochemical findings presents diagnostic difficulties. It is suspected that idiopathic chondrolysis is a metabolic disorder of chondrocytes, triggered by environment circumstances in susceptible individuals. Idiopathic chondrolysis is probably one of the most common causes of coxarthrosis in women.

  18. Obtaining large-scale funding for empowerment-oriented qualitative research: a report from personal experience.

    Padgett, Deborah K; Henwood, Benjamin F

    2009-06-01

    Obtaining funding for qualitative research remains a challenge despite greater openness to methodological pluralism. Such hurdles are presumably compounded when the proposed study employs empowerment theory, rendering it susceptible to charges of elevating ideology over rigor. This article draws on the authors' experience in securing large-scale funding for an empowerment-oriented qualitative study of homeless mentally ill adults. Lessons learned include the importance of weaving empowerment theory into the proposal's "argument," and infusing empowerment values into study protocols while simultaneously paying close attention to rigorous and transparent methods. Additional benefits accrue from having prior relationships with study sites and being willing to revise and resubmit proposals whenever possible. Though representing a fraction of all externally funded projects in the United States, qualitative research has tremendous untapped potential for success in this competitive arena-success that need not entail surrendering a commitment to empowerment values.

    1995-12-01

    This report summarizes the technical progress made in the past three years on CRADA No. 1078, Molecular Engineering of Polymer Alloys. The thrust of this CRADA was to start with the basic ideas of PRISM theory and develop it to the point where it could be applied to modeling of polymer alloys. In this program, BIOSYM, Sandia and the University of Illinois worked jointly to develop the theoretical techniques and numerical formalisms necessary to implement the theoretical ideas into commercial software aimed at molecular engineering of polymer alloys. This CRADA focused on developing the techniques required to make the transition from theory to practice. These techniques were then used by BIOSYM to incorporate PRISM theory and other new developments into their commercial software.

    Loss, failure and desertion are those words, which better describe the most frequent difficulties incurred by teenagers, and their relation to the school environment, and indicate, as well, the lack of connection between individual aspirations and school achievements obtained. Despite the likelihood of school difficulties throughout the entire educational career, from the kindergarten to the college, we are able to recognize certain specific "disturbances" which come out during the adolescence, basically relating to the school experiences. School failure, school desertion and school abandonment are, in fact, issues mainly discussed in coincidence with the beginning of the adolescent age and the attending of the high school. The aetiopathogenesis of school discomfort is mostly determined by more than only one factor: psychological, physical, cognitive and environmental aspects, all together, contribute in various ways, to the rise and persisting of the above described problems. Suggesting a univocal characterization of the adolescent with school difficulties, is indeed a hard task, since school failure is not an exclusive feature of only one kind of personality or the expression of only one type of conflict. Once identified the individuals more subject to risk, and the warning signs of actual uneasiness, it is important therefore to intervene timely and in different ways in order to avoid the worsening or the excessive extension of the school difficulties and of their frequent and serious consequences on the teenagers' individual and domestic well-being. Such type of prevention definitely belongs to the Adolescent Medicine, and must be developed on different levels, by involving not only the teenagers, but also their families, the school, and the whole social environment in which the teenagers live and with which they interact.

    2011-01-01

    Construal of the self as independent or interdependent in relation to others has been found to correlate significantly with social anxiety symptom ratings, raising concerns about possible cultural bias in these measures for Asian Americans. To investigate the validity of self-reported social anxiety symptoms, we examined the role of ethnicity in the associations among social anxiety, self-construal, and adaptive social functioning in a sample of 229 Asian- and European American college students. Results revealed that ethnicity moderated the relationship between self-construal and social anxiety such that interdependent self-construal was associated with higher social anxiety only for first generation Asian Americans. However, there were no significant ethnic differences in the associations between social anxiety self-reports and several measures of social functioning.

    2010-09-01

    Self-reports of the ability to engage in instrumental activities of daily living (IADLs) among older adults are known to be related to personality traits. However, self-reports are sometimes discrepant with performance-based IADL assessments, and little is known about personality associations with objective functionality or with poor insight about functional deficits. This study examined the NEO Personality Inventory-Revised profiles associated with (a) self-report of functional problems, (b) functional errors evidenced on performance-based IADL assessment, and (c) discrepancies between self-report and performance. Participants were 65 community-dwelling individuals ranging in age from 60 to 87 years. The results showed that self-report of IADL problems are associated with higher neuroticism and lower conscientiousness, actual IADL difficulties with higher neuroticism and lower agreeableness and openness to experience, underreporting of problems with higher conscientiousness, and overreporting of problems with higher extraversion and neuroticism. These relationships were partly mediated by age, education, and cognitive status. When unique personality associations with self-report and performance were examined, neuroticism and agreeableness, respectively, emerged as the strongest predictors.

  4. The strengths and difficulties questionnaire as a predictor of parent-reported diagnosis of autism spectrum disorder and attention deficit hyperactivity disorder.

    Directory of Open Access Journals (Sweden)

    Ginny Russell

    Full Text Available The Strengths and Difficulties Questionnaire (SDQ is widely used as an international standardised instrument measuring child behaviour. The primary aim of our study was to examine whether behavioral symptoms measured by SDQ were elevated among children with autism spectrum disorder (ASD and attention deficit hyperactivity disorder (ADHD relative to the rest of the population, and to examine the predictive value of the SDQ for outcome of parent-reported clinical diagnosis of ASD/ADHD. A secondary aim was to examine the extent of overlap in symptoms between children diagnosed with these two disorders, as measured by the SDQ subscales. A cross-sectional secondary analysis of data from the Millennium Birth Cohort (n = 19,519, was conducted. Data were weighted to be representative of the UK population as a whole. ADHD or ASD identified by a medical doctor or health professional were reported by parents in 2008 and this was the case definition of diagnosis; (ADHD n = 173, ASD n = 209, excluding twins and triplets. Study children's ages ranged from 6.3-8.2 years; (mean 7.2 years. Logistic regression was used to examine the association between the parent-reported clinical diagnosis of ASD/ADHD and teacher and parent-reported SDQ subscales. All SDQ subscales were strongly associated with both ASD and ADHD. There was substantial co-occurrence of behavioral difficulties between children diagnosed with ASD and those diagnosed with ADHD. After adjustment for other subscales, the final model for ADHD, contained hyperactivity/inattention and impact symptoms only and had a sensitivity of 91% and specificity of 90%; (AUC = 0.94 (95% CI, 0.90-0.97. The final model for ASD was composed of all subscales except the 'peer problems' scales, indicating of the complexity of behavioural difficulties that may accompany ASD. A threshold of 0.03 produced model sensitivity and specificity of 79% and 93% respectively; AUC = 0.90 (95% CI, 0.86-0.95. The

    Full Text Available This study evaluated whether adolescents who report having been bullied, being bullies, or report both being a bully and being bullied experience more sleep difficulties than children uninvolved in bullying. The study drew upon cognitive theories of insomnia, investigating whether the extent to which young people report worrying about bullying can moderate associations between victimization and sleep difficulties. Participants were 5420 adolescents who completed a self-report questionnaire. Pure Victims (OR = 1.72, 95% CI [1.07, 2.75], Pure Bullies (OR = 1.80, 95% CI [1.16, 2.81], and Bully-Victims (OR = 2.90, 95% CI [1.17, 4.92] were all more likely to experience sleep difficulties when compared to uninvolved young people. The extent to which young people reported worrying about being bullied did not moderate the links between victimization and sleep difficulties. In this way, bullying is clearly related to sleep difficulties among adolescents but the conceptual reach of the cognitive model of insomnia in this domain is questioned.

  8. Desirable Difficulties in Vocabulary Learning.

    Science.gov (United States)

    Bjork, Robert A; Kroll, Judith F

    2015-01-01

    In this article we discuss the role of desirable difficulties in vocabulary learning from two perspectives, one having to do with identifying conditions of learning that impose initial challenges to the learner but then benefit later retention and transfer, and the other having to do with the role of certain difficulties that are intrinsic to language processes, are engaged during word learning, and reflect how language is understood and produced. From each perspective we discuss evidence that supports the notion that difficulties in learning and imposed costs to language processing may produce benefits because they are likely to increase conceptual understanding. We then consider the consequences of these processes for actual second-language learning and suggest that some of the domain-general cognitive advantages that have been reported for proficient bilinguals may reflect difficulties imposed by the learning process, and by the requirement to negotiate cross-language competition, that are broadly desirable. As Alice Healy and her collaborators were perhaps the first to demonstrate, research on desirable difficulties in vocabulary and language learning holds the promise of bringing together research traditions on memory and language that have much to offer each other.

  11. Development of a self-reporting tool to obtain a Combined Index of Severity of Fibromyalgia (ICAF*

    Directory of Open Access Journals (Sweden)

    Esteve-Vives Joaquim

    2010-01-01

    Full Text Available Abstract Background Fibromyalgia is a syndrome with heterogeneous symptoms. The evaluation in the clinical setting usually fails to cover the complexity of the syndrome. This study aims to determine how different aspects of fibromyalgia are inter-related when measured by means of a self-reporting tool. The objective is to develop a more complete evaluation model adjusted to the complexity and multi-dimensional nature of the syndrome. Methods Application was made of the Fibromyalgia Impact Questionnaire, the Hospital Anxiety and Depression Scale, the Brief Pain Inventory, the Fatigue Assessment Scale, the Health Assessment Questionnaire, the General Health Questionnaire (GHQ-28, the Chronic Pain Coping Inventory, the Arthritis Self-efficacy Scale and the Sleep Quality Scale. An assessment was made, on the basis of clinical interviews, case histories and specific tests, of the patient sociodemographic data, comorbidity, physical exploration and other clinical indexes. An exploratory factor analysis was made, with comparisons of the clinical index scores in extreme groups of patients. Results The ICAF composed of 59 items was obtained, offering four factors that explain 64% of the variance, and referred to as Emotional Factor (33.7%, Physical-Activity (15%, Active Coping (9% and Passive Coping (6.3%. A t-test between the extreme scores of these factors in the 301 patients revealed statistically significant differences in occupational status, medically unexplained syndromes, number of tender points, the six-minutes walk test, comorbidity and health care costs. Conclusions This study offers a tool allowing more complete and rapid evaluation of patients with fibromyalgia. The test intrinsically evaluates the emotional aspects: anxiety and depression, and their impact upon social aspects. It also evaluates patient functional capacity, fatigue, sleep quality, pain, and the way in which the patient copes with the disease. This is achieved by means of a

    2012-10-01

    Albanian is an Indo-European language with a shallow orthography, in which there is an absolute correspondence between graphemes and phonemes. We aimed to know reading strategies used by Albanian disabled children during word and pseudoword reading. A pool of 114 Kosovar reading disabled children matched with 150 normal readers aged 6 to 11 years old were tested. They had to read 120 stimuli varied in lexicality, frequency, and length. The results in terms of reading accuracy as well as in reading times show that both groups were affected by lexicality and length effects. In both groups, length and lexicality effects were significantly modulated by school year being greater in early grades and later diminish in length and just the opposite in lexicality. However, the reading difficulties group was less accurate and slower than the control group across all school grades. Analyses of the error patterns showed that phonological errors, when the letter replacement leading to new nonwords, are the most common error type in both groups, although as grade rises, visual errors and lexicalizations increased more in the control group than the reading difficulties group. These findings suggest that Albanian normal children use both routes (lexical and sublexical) from the beginning of reading despite of the complete regularity of Albanian, while children with reading difficulties start using sublexical reading and the lexical reading takes more time to acquire, but finally both routes are functional.

    2012-01-01

    Carpal tunnel syndrome (CTS) may be overlooked in the absence of typical sensory symptoms. Two patients with CTS lacked the attendant sensory symptoms but experienced difficulties performing a pinching action behind the back (manipulation of the buckle of a baby sling or the hook of a brassiere), a mode of pinching that required wrist flexion. The causative mechanism was probably exacerbation of a latent weakness of the intrinsic muscles of the thumb by wrist flexion, in which the strength of the extrinsic flexors of the thumb and index finger were decreased due to loosening of the tendons. Such symptoms, induced by a specific wrist position, may be help to diagnose a latent weakness in the intrinsic muscles of the thumb, present in patients with CTS.

  3. Potential usefulness of CTC detection in follow up of prostate cancer patients. A preliminary report obtained by using Adnagene platform

    2013-12-01

    Full Text Available Objective: Prostate cancer (PCa represents one of the most important medical problems for males, being the second major cause of cancer death. Routinely, PCa patients are followed up with both periodic evaluation of serum PSA levels and imaging. Recently, alternative laboratory methods were proposed for PCa patients’ monitoring, with contrasting results. Aim of the present study was to evaluate the usefulness of a new commercially CE-IVD kit for detection of prostate circulating tumour cells. Our intention was to verify the Adnagene platform usefulness to identify patients with disease progression, whatever treatment ongoing, in order to modify the therapeutic process even before treatment failure is evident with imaging methods. Materials and Methods: Twenty-one patients were enrolled and subdivided into three groups: n = 10 high risk tumor PCa patients; n = 6 low risk PCa patients; n = 5 sbjects without any signs of PCa. AdnaTest Prostate Cancer kit was used for enrichment and molecular characterization of prostate circulating tumour cells. Results: Healthy subjects (with BPH and patients without metastases resulted as negative, while 3 out of 10 high risk PCa patients were positive at least for one molecular marker like PSA, while only two showed positivity for PSMA mRNA. Our results indicate that the test specificity is 100% and the sensitivity is 100%; of course the sample is too small to give it statistical validity. In detail we verified that only the “not responder” patients resulted positive for AdnaTest. Conclusions: The present preliminary report provides evidence that isolation and detection of circulating tumour cells (CTCs is feasible and it may be useful in the follow-up of patients with advanced prostate cancer. If the results of this preliminary study would be confirmed by a large prospective cohort study, it could be demonstrated that this test is a rapid diagnostic method, based on the analysis of a blood sample and

As a result, the morphologic right ventricle lies to the left of the morphologic left ventricle and becomes the systemic ventricle. The morphologic right ventricle gives rise to the aorta, which is anterior of the pulmonary artery. As a result of discordance at both the atrioventricular (AV and the great vessel level, physiologic blood flow remains normal. It was shown that the decreased RV functions are related with increased mortality rates in long term follow up. Most of these patients have RV failure due to abnormal pressure load of systemic RV, imbalance between O2 supply and myocardial demand and development of systemic AV valvular regurgitation in most of the patients. Therefore, the most important and difficult point in the follow up of these patients is evaluation of RV functions and degree of systemic AV valve regurgitation. In this review, we discussed the difficulties in the diagnosis and treatment of these patients in the light of a typical TGA case.

    Social and emotional loneliness negatively impact several areas of health, including sleep. However, few comprehensive population-based studies have evaluated this relationship. Over 12,000 students aged 21-35 years who participated in the student survey for higher education in Norway (the SHoT study) were assessed. Loneliness was assessed using the Social and Emotional Loneliness Scale. Difficulty initiating and maintaining sleep (DIMS) was assessed by a single-item subjective response on the depression scale of the Hopkins Symptoms Checklist (HSCL-25). Social loneliness was associated with more serious DIMS (unadjusted proportional odds-ratio [OR] = 2.69, 95% CI = 2.46-2.95). This association was attenuated following adjustment for anxiety (adjusted OR = 1.92, 95% CI = 1.75-2.10) and depression (adjusted OR = 1.48, 95% CI = 1.34-1.63), however was not substantially altered when all demographics and psychological distress were accounted for (fully adjusted OR = 1.46, 95% CI = 1.30-1.63). Emotional loneliness was also associated with more serious DIMS (unadjusted proportional OR = 2.33, 95% CI = 2.12-2.57). Adjustment for anxiety (adjusted OR = 1.96, 95% CI = 1.78-2.15) and depression (adjusted OR = 1.64, 95% CI = 1.48-1.80) attenuated, but did not extinguish this relationship in the fully adjusted model (adjusted OR = 1.22, 95% CI = 1.09-1.31). Mediation analyses revealed that the social loneliness-DIMS association was fully attributed to psychological distress, while the emotional loneliness-DIMS association was only partially mediated, and a direct association was still observed. Associations between social and emotional loneliness and subjective DIMS were embedded in a larger pattern of psychological distress. Mitigating underlying feelings of loneliness may reduce potentially deleterious effects on sleep health and psychological wellbeing in young adults.

    This study examined adults' self-reported understanding and formatting preferences of medical statistics, confidence in self-care and ability to obtain health advice or information, and perceptions of patient-health-care provider communication measured through dual survey modes (random digital dial and mail). Even while controlling for sociodemographic characteristics, significant differences in regard to adults' responses to survey variables emerged as a function of survey mode. While the analyses do not allow us to pinpoint the underlying causes of the differences observed, they do suggest that mode of administration should be carefully adjusted for and considered.

Pretende-se destacar as características clínicas, discutindo as implicações do diagnóstico precoce para a evolução dos pacientes. DESCRIÇÃO DO CASO: Uma adolescente com diagnóstico de tricotilomania "pura" e outra menina cujo quadro estava associado ao transtorno obsessivo-compulsivo. Embora com o tratamento, a evolução de ambas tenha sido favorável, houve demora significativa para estabelecer o diagnóstico e encaminhá-las a um serviço de saúde mental, com prejuízos escolares e sociais. COMENTÁRIOS: A tricotilomania difere dos quadros benignos e transitórios de arrancar cabelos observados nos primeiros anos de vida e ainda é subdiagnosticada. A vergonha dos sintomas observada nos portadores e o desconhecimento por parte dos profissionais de saúde contribuem para essa situação. O quadro pode ser grave, particularmente se acompanhado de tricofagia. Profissionais da saúde precisam identificar o transtorno precocemente e encaminhar as crianças para tratamento especializado antes das possíveis complicações clínicas e repercussões psicossociaisOBJECTIVE: To report two cases of trichotillomania, an underdiagnosed psychiatric disorder that may be associated with important social and clinical problems. The clinical features will be highlighted considering the implications of early diagnosis on patients' outcome. CASE DESCRIPTION: An adolescent with isolated trichotillomania and another girl whose symptoms were associated with obsessive-compulsive disorder are described. Although both patients presented a favorable outcome with treatment, there was a significant delay in establishing the diagnosis and in referring them to a mental health service, leading to negative impact in educational and social domains.

    1991-06-01

    Student teachers who are recent migrants to Australia from non-English-speaking countries experience difficulties in mathematics method courses and in teaching practice, but there are no published reports of research into their difficulties. This paper reports on a preliminary investigation into how students with limited English skills perceive their problems and how they think courses could be adapted to meet their needs. Information was obtained from a questionnaire, by conversation with individual students, by observation of micro-teaching sessions and teaching practice, and from a student counsellor. The factor which most concerned the repondents to the questionnaire was the difficulty which pupils might have in understanding their speech. The results of the study highlight the present lack of resources to provide intensive training for student teachers in the use of specifically mathematical English. The teacher education course was identified as the only vehicle available to them for improving their English.

    Full Text Available Background. Gastric volvulus refers to a torsion of all or part of the stomach that may cause an obstruction of the foregut. The clinical symptoms of gastric volvulus range from asymptomatic to life-threatening and thus must be rapidly diagnosed. However, the presenting symptoms of gastric volvulus vary widely, which may cause diagnosis to be delayed or missed. Objective. Describe varying presentations of gastric volvulus (including a case report of a rare presentation, pathophysiology of the entity, and how to diagnose/treat the phenomenon. Design/Method. Article review and case presentation. Results. Our patient was taken to the operating room for a gastropexy and G-tube placement. During surgery, the stomach was redundant and large, but not currently torsed, consistent with intermittent organoaxial volvulus. There are several approaches to classifying gastric volvulus as well as different theories on how to treat the volvulus based on type and degree of rotation that this article aims to detail more thoroughly. Conclusion. There are a growing number of case reports describing gastric volvulus, which had historically been viewed as a rare finding. The presenting symptoms of gastric volvulus commonly mimic other, more benign newborn diagnoses, and thus can be difficult to diagnose. We present our patient as well as an article review of other cases to highlight the diverse presentations of gastric volvulus so this potentially devastating disease can be diagnosed quickly with prompt treatment initiation.

    Full Text Available Objective : To analyze aspects related to the diagnostic difficulty in patients with bacterial spondylodiscitis. Methods : Cross-sectional observational study with retrospective data collected in the period from March 2004 to January 2014.Twenty-one patients diagnosed with bacterial spondylodiscitis were analyzed. Results : Women were the most affected, as well as older individuals. Pain in the affected region was the initial symptom in 52% of patients, and 45.5% of the patients had low back pain, and those with dorsal discitis had back pain as the main complaint; the patients with thoracolumbar discitis had pain in that region, and only one patient had sacroiliac discitis. The average time between onset of symptoms and treatment was five months. The lumbar segment was the most affected with 11 cases (52%, followed by thoracolumbar in 24%, dorsal in 19% of cases and a case in the sacroiliac segment. Only seven patients had fever. Pain in the affected level was coincidentally the most common symptom. Conclusions : Early diagnosis of bacterial spondylodiscitis remains a challenge due to the nonspecific signs and symptoms reported by the patient and the wide variability of laboratory results and imaging. The basis for early diagnosis remains the clinical suspicion at the time of initial treatment.

    Referenced as both supporting and weakening the case for parenting by homosexuals, 57 life-story narratives of children with homosexual parents published by Rafkin in 1990 and Saffron in 1996 were subjected to content analysis. Children mentioned one or more problems or concerns in 48 (92%) of 52 families. Of the 213 scored problems, 201 (94%) were attributed to the homosexual parent(s). Older daughters in at least 8 (27%) of 30 families and older sons in at least 2 (20%) of 10 families described themselves as homosexual or bisexual. These findings are inconsistent with propositions that children of homosexuals do not differ appreciably from those who live with married parents or that children of homosexuals are not more apt to engage in homosexuality.

    2016-01-01

    We found calcified pulmonary nodules in a middle-aged female mummy discovered from 350-yr-old Joseon tomb of Korea. In the CT scan, we found six radiopaque nodules in right lung, through the levels of thoracic vertebrae 1 to 6. We also found presumptive pleural adhesions in right thoracic cavity of CT images. We re-confirmed radiological findings by our post-factum dissection on the same mummy. By the differential diagnosis, we speculate that the radiopaque calcification nodules and associated pleural adhesion could have been caused by tuberculosis. This is the first-ever report on the pulmonary tuberculosis identified in archaeologically obtained, pre-modern Korean samples. PMID:26770051

    Microsaccades are involuntary, small-magnitude saccadic eye movements that occur during attempted visual fixation. Recent research has found that attention can modulate microsaccade dynamics, but few studies have addressed the effects of task difficulty on microsaccade parameters, and those have obtained contradictory results. Further, no study to date has investigated the influence of task difficulty on microsaccade production during the performance of non-visual tasks. Thus, the effects of task difficulty on microsaccades, isolated from sensory modality, remain unclear. Here we investigated the effects of task difficulty on microsaccades during the performance of a non-visual, mental arithmetic task with two levels of complexity. We found that microsaccade rates decreased and microsaccade magnitudes increased with increased task difficulty. We propose that changes in microsaccade rates and magnitudes with task difficulty are mediated by the effects of varying attentional inputs on the rostral superior colliculus activity map.

    Leading models of sexual dysfunction, such as those proposed by Masters and Johnson (1970), Barlow (1986), and Janssen, Everaerd, Spiering, and Janssen (2000), emphasize the role of anxiety and self-monitoring in the development and persistence of sexual difficulties. These models have considerable explanatory power, but focus on the intrapersonal factors that yield anxiety and self-monitoring. Accounting for the interpersonal context in which sexual activity occurs is also likely to be important. For example, anxiety and self-monitoring may arise from negative, yet accurate, predictions about how one's partner will respond to one's own sexual functioning difficulties. The current studies describe the development and validation of the Response to Sexual Difficulties Scale (RSDS), which was designed to assess how one expects one's partner to respond to one's own sexual difficulties (RSDS-Own Difficulties) and how one expects oneself to respond to one's partner's sexual difficulties (RSDS-Partner Difficulties). Study 1 established the initial reliability and construct validity of the RSDS-Own Difficulties in a sample of adults in committed relationships (N = 59). Study 2 further examined the construct and discriminant validity of the RSDS Own Difficulties and Partner Difficulties in a sample of heterosexual couples (N = 87). Results indicated that both measures had strong internal consistency and were not redundant with measures of mood or personality. Scores on the RSDS-Own Difficulties and Partner Difficulties were strongly associated, indicating that reports of one's own response to one's partner's difficulty matched the partner's assessment of the reaction. RSDS scores predicted sexual functioning, relationship satisfaction, sexual satisfaction, and sexual communication. The RSDS may, then, provide a useful means of assessing the role of interpersonal factors in the development and persistence of sexual difficulties.

  10. Likelihood of obtaining Structured Interview of Reported Symptoms (SIRS) and SIRS-2 elevations among forensic psychiatric inpatients with screening elevations on the Miller Forensic Assessment of Symptoms Test.

    2016-12-01

    The Miller Forensic Assessment of Symptoms Test (M-FAST) was designed as a screening measure for feigned psychiatric symptoms. When M-FAST Total Scores are elevated (raw score ≥6), the test manual recommends follow-up with a more comprehensive measure of feigning, such as the widely used and researched Structured Interview of Reported Symptoms (SIRS) or the revised version of the test (SIRS-2). The purpose of the current study was to evaluate how often M-FAST screening elevations are associated with subsequent elevations on the SIRS or SIRS-2. The sample included archival data from 100 forensic psychiatric inpatients who obtained M-FAST Total Score elevations ≥6 during screening and were subsequently administered the SIRS (that was also rescored using SIRS-2 criteria). Among examinees who elevated the M-FAST over the recommended cutoff, 66.0% met standard SIRS feigning criteria, 42% met SIRS-2 criteria for feigning, and 81.0% obtained at least 1 SIRS/SIRS-2 elevation in the Probable Feigning range or higher. These results are consistent with the M-FAST manual guidelines, which support the use of the ≥6 M-FAST cutoff score to screen for potential feigning (but not as an independent marker of feigning). A higher M-FAST cutoff score of ≥16 was associated with subsequently meeting full SIRS criteria for feigning in 100.0% of protocols. Because the SIRS criteria were designed to have very low false positive rates, these findings indicate that more confident assertions about feigning can be made when elevations reach this level on the MFAST.

    The impact of kidney donation on the ability to change or initiate health or life insurance following donation is unknown. To quantify this risk, we surveyed 1046 individuals who donated a kidney at our center between 1970 and 2011. Participants were asked whether they changed or initiated health or life insurance after donation, and if they had any difficulty doing so. Among 395 donors who changed or initiated health insurance after donation, 27 (7%) reported difficulty; among those who reported difficulty, 15 were denied altogether, 12 were charged a higher premium and 8 were told they had a preexisting condition because they were kidney donors. Among 186 donors who changed or initiated life insurance after donation, 46 (25%) reported difficulty; among those who reported difficulty, 23 were denied altogether, 27 were charged a higher premium and 17 were told they had a preexisting condition because they were kidney donors. In this single-center study, a high proportion of kidney donors reported difficulty changing or initiating insurance, particularly life insurance. These practices by insurers create unnecessary burden and stress for those choosing to donate and could negatively impact the likelihood of live kidney donation among those considering donation.

    This study examined whether economic difficulties are associated with subsequent disability retirement while controlling for covariates. Survey data among middle-aged employees of the City of Helsinki in 2000-2002 were linked with the Finnish Centre for Pensions register data on all-cause disability retirement among women (n=4816) and men (n=1354) until the end of 2010. Additionally, disability retirement due to musculoskeletal diseases and mental disorders (ICD-10) was examined among women. Frequency in difficulties paying pills and buying food and clothes, and covariates (occupational class, income, housing tenure, and work- and health-related covariates) were self-reported at baseline. Hazard ratios (HR) and their 95% confidence intervals (95% CI) were calculated from Cox regression analysis. Frequent economic difficulties were associated with all-cause disability retirement after adjusting for age among both women (HR=2.11; 95% CI 1.63-2.73) and men (HR=2.69; 95% CI 1.65-4.41). Adjustment for covariates somewhat attenuated the associations, but they remained. Economic difficulties were also associated with disability retirement due to both mental disorders (HR=3.29; 95% CI 1.98-5.46) and musculoskeletal diseases (HR=1.85; 95% CI 1.24-2.75) among women. Adjustments made a minor contribution to the risk of disability retirement due to mental disorders, whereas the risk of disability retirement due to musculoskeletal diseases reduced after considering socioeconomic circumstances. Conclusions: economic difficulties are independently associated with disability retirement. Thus, they should be considered in attempts to tackle early exit from the labour market due to disability. © 2015 the Nordic Societies of Public Health.

  14. Framing difficulties in quantum mechanics

    Modir, Bahar; Sayre, Eleanor C

    2016-01-01

    Students' difficulties in quantum mechanics may be the result of unproductive framing and not fundamental inability to solve the problems or misconceptions about physics content. We observed groups of students solving quantum mechanics problems in an upper-division physics course. Using the lens of the epistemological framing, we investigated four frames in our observational data: algorithmic math, conceptual math, algorithmic physics, and conceptual physics. We then used our framework to seek an underlying structure to the long lists of published difficulties that span many topics in quantum mechanics. We mapped descriptions of published difficulties into errors in epistemological framing and resource use. We analyzed descriptions of students' problem solving to find their frames, and compared students' framing to framing (and frame shifting) required by problem statements. We found three categories of error: mismatches between students' framing and problem statement framing; inappropriate or absent transiti...

    Full Text Available Zach Radcliff, Allison Baylor, Bruce Rybarczyk Department of Psychology, Virginia Commonwealth University, Richmond, VA, USA Abstract: Sleep is a critical component of healthy development for youth, with cascading effects on youth’s biological growth, psychological well-being, and overall functioning. Increased sleep difficulties are one of many disruptions that adopted youth may face throughout the adoption process. Sleep difficulties have been frequently cited as a major concern by adoptive parents and hypothesized in the literature as a problem that may affect multiple areas of development and functioning in adopted youth. However, there is limited research exploring this relationship. Using a biopsychosocial framework, this paper reviews the extant literature to explore the development, maintenance, and impact of sleep difficulties in adopted youth. Finally, implications for future research and clinical interventions are outlined. Keywords: adoption, sleep, youth

    2015-01-01

    Based on recent studies regarding the advantages of flapless immediate implants on the maintenance of the soft tissue architecture (especially at papillae level) in those situations where it is necessary to extract an anterior tooth, this case report describes a clinical procedure designed to replace a hopeless central incisor (2.1) showing root resorption adjacent to an implant-supported crown (1.1), whose gingival margin is 2 mm coronal regarding the hopeless tooth to be replaced. After the extraction of the hopeless tooth (2.1), a flapless immediate implant was placed. The implant-bone gap was then filled with bone substitute and a palatal connective tissue graft was placed ad modum saddle extending at buccal level from apical to the mucogingival line, sealing the socket and extending until 6 mm at palatal level ad modum saddle. This procedure allowed symmetry of the soft tissue margins between the two implants (1.1 and 2.1) to be obtained as well as the preservation of the inter-implant papillae (1.1).

    2015-01-01

    Boundary conditions (BCs) are considered as an important topic that advanced physics under- graduates are expected to understand and apply. We report findings from an investigation of student difficulties using boundary conditions (BCs) in electrodynamics. Our data sources include student responses to traditional exam questions, conceptual survey questions, and think-aloud interviews. The analysis was guided by an analytical framework that characterizes how students activate, con- struct, execute, and reflect on boundary conditions. Common student difficulties include: activating boundary conditions in appropriate contexts; constructing a complex expression for the E&M waves; mathematically simplifying complex exponentials and checking if the reflection and transmission co- efficient are physical. We also present potential pedagogical implications based on our observations.

    Full Text Available Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning.

    2014-06-01

    Full Text Available Reports of functional problems are common among Veterans who served post-9/11 (more than 25% report functional difficulties in at least one domain. However, little prospective work has examined the risk and protective factors for functional difficulties among Veterans. In a sample of recently separated Marines, we used stepwise logistic and multiple regressions to identify predictors of functional impairment, including work-related problems, financial problems, unlawful behavior, activity limitations due to mental health symptoms, and perceived difficulty reintegrating into civilian life. Posttraumatic stress disorder symptoms assessed both before and after military separation significantly predicted functional difficulties across all domains except unlawful behavior. Certain outcomes, such as unlawful behavior and activity limitations due to mental health symptoms, were predicted by other or additional predictors. Although several forms of functioning were examined, the list was not exhaustive. The results highlight a number of areas where targeted interventions may facilitate the reintegration of military servicemembers into civilian life.

    In contrast to yeast, bacteria have a wide substrate spectrum. Certain bacteria can convert xylose into ethanol. Thermo-anaerobic bacterium ethanolicus and its mutants can also hydrolyse oligomeric xylane and produce alcohol. An elegant and simple process to obtain pentose and pentosane from ligno-cellulose is the steam pressure extraction process, in which the hemi-cellulose can be obtained by prewashing after brief steam pressure treatment between 170 and 210degC. By controlling the parameters of temperature and time, the hemicellulose yield can be optimized and the production of sugar decay products can be minimised. The batch fermentation of a polymer beech wood xylane after integrated hydrolysis and sterilisation gave an ethanol concentration of 5.3 g/litre after 94 hours.

    Difficulty and complexity are important factors that occur in every test questions. These two factors will also affect the reliability of the test. Hence, difficulty and complexity must be considered by educators during preparation of the test questions. The relationship between difficulty and complexity is studied. Complexity is defined as the level in Bloom's Taxonomy. Difficulty is represented by the proportion of students scoring between specific score intervals. A chi-square test of independence between difficulty and complexity was conducted on the results of a continuous assessment of a third year undergraduate course, Probability Theory. The independence test showed that the difficulty and complexity are related. However, this relationship is small.

    2016-09-01

    Dysplasia epiphysealis hemimelica, also known as Trevor's disease, is a rare developmental disorder with osteocartilagenous overgrowth of the epiphysis or epiphyseal equivalent. The condition bears similarities to osteochondroma in terms of its radiographic appearance, but differs in its pathobiology and geographic occurrence. Unlike the metaphyseal occurrence of osteochondromata, it arises from the epiphysis. The clinical presentation is wide and varied, but mechanical symptoms and deformities predominate. Early reports of the condition suggested involvement of the lower limbs only. However, since then, numerous reports have indicated a more generalized distribution. Difficulties in management and recurrence rates seem to hinge on whether its origin is intra-articular or extra-articular. A new classification system to include these parameters is discussed.

    Full Text Available The National Senior Certificate examination is the most important school examination in South Africa. Analysis of learners’ performance in Mathematics in this examination is normally carried out and presented in terms of the percentage of learners who succeeded in the different bands of achievement. In some cases item difficulties are presented – item refers to the subsection of each examination question. Very little attention is paid to other diagnostic statistics, such as the discrimination indices and item difficulties taking into consideration partial scores examinees achieve on items. In this article we report on a study that, in addition to the usual item difficulties, includes a discrimination index of item difficulties taking into account partial scores examinees achieved. The items, considered individually, are analysed in relation to the other items on the test. The focus is on the topic sequences and series and the data were obtained from a stratified sample of the marked scripts of the candidates who wrote the National Senior Certificate examination in Mathematics in November 2010. Rasch procedures were used for the analysis. The findings indicate that learners perform differently on subsections of topics, herein referred to as items, and that focusing on scores for full topics potentially mask these differences. Mathematical explanations are attempted to account for difficulties learners exhibit in these subsections, using a hierarchy of scale. The findings and our analysis indicate that a form of measurement-driven testing could have beneficial results for teaching. Also, for some items the difficulty obtained from the work of examinees runs counter to the commonly perceived wisdom that an examination ought to be structured in such a way that the less difficult items are at the start of a topic. An explanatory device anchored around the construct of ‘familiarity with problem types through repeated productive practice’ is

    2011-01-01

    Full Text Available Background: Hemisphericity or individual difference in the preference to use the left or the right hemispheric mode of information processing has been associated with various emotion-related differences. For example, the right hemisphericity has been linked with inhibition of emotional expression, feeling of tension, greater impulsivity etc. These observations suggest that right hemisphericity may be associated with greater difficulties in regulating emotions. However, direct empirical tests of such theoretical proposition are very thin. Aim: In view of this, the present study aims to investigate how and to what extent individual difference in hemispheric preference relate to emotion regulation. Materials and Methods: Thirty-two right-handed male subjects in the age range 18 to 20 years were assessed on self-report measures of hemispheric preference and emotion regulation difficulties. The correlation between dimensions of hemispheric preference and difficulties in regulating emotions was computed. A series of stepwise multiple regression analyses were also done to explore the relative significance of various dimensions of hemispheric preference in predicting emotion regulation difficulties. Results: The findings revealed that in general a preference for the right hemispheric mode of information processing was associated with greater emotion regulation difficulties. The correlation analysis indicated that while impulse control difficulties and difficulties in engaging goal directed behavior was associated with preference for almost all the right hemispheric mode of information processing, the nonacceptance of emotional responses and limited access to emotion regulation was related to preference for only global/synthetic (a right hemispheric mode of information processing. Similarly, the lack of emotional clarity facet of emotion regulation difficulties correlated significantly with a preference for the emotional mode of information processing

    Abdu Mohammed Al-Mekhlafi

    2011-07-01

    Full Text Available The role of grammar instruction in an ESL/EFL context has been for decades a major issue for students and teachers alike. Researchers have debated whether grammar should be taught in the classroom and students, for their part, have generally looked upon grammar instruction as a necessary evil at best, and an avoidable burden at worst. The paper reports a study undertaken to investigate the difficulties teachers face in teaching grammar to EFL students as well as those faced by students in learning it, in the teachers' perception. The study aimed to find out whether there are significant differences in teachers' perceptions of difficulties in relation to their gender, qualification, teaching experience, and the level they teach in school, thus providing insights into their own and their students' difficulties. Mean scores and t-test were used to interpret the data. The main findings are reported with implications.

    Semenova, O A; Machinskaya, R I

    2015-01-01

    A total number of 172 children aged 10-12 were electrophysiologically and neuropsychologically assessed in order to analyze the influence of the functioning of brain regulatory systems onto the voluntary regulation of cognitive performance during the preteen years. EEG patterns associated with the nonoptimal functioning of brain regulatory systems, particularly fronto-thalamic, limbic and fronto-striatal structures were significantly more often observed in children with learning and behavioral difficulties, as compared to the control group. Neuropsychological assessment showed that the nonoptimal functioning of different brain regulatory systems specifically affect the voluntary regulation of cognitive performance. Children with EEG patterns of fronto-thalamic nonoptimal functioning demonstrated poor voluntary regulation such as impulsiveness and difficulties in continuing the same algorithms. Children with EEG patterns of limbic nonoptimal functioning showed a less pronounced executive dysfunction manifested only in poor switching between program units within a task. Children with EEG patterns of fronto-striatal nonoptimal functioning struggled with such executive dysfunctions as motor and tactile perseverations and emotional-motivational deviations such as poor motivation and communicative skills.

    2013-12-01

    Respiratory difficulties and breathing disorders in achondroplasia are thought to underlie the increased risk for sudden infant death and neuropsychological deficits seen in this condition. This review evaluates literature regarding respiratory dysfunctions and their sequelae in patients with achondroplasia. The limited number of prospective studies of respiratory disease in achondroplasia means that observational studies and case series provide a large proportion of the data regarding the spectrum of respiratory diseases in achondroplasia and their treatments. Amongst clinical respiratory problems described, snoring is the commonest observed abnormality, but the reported incidence of obstructive sleep apnoea (OSA) shows wide variance (10% to 75%). Reported treatments of OSA include adenotonsillectomy, the use of CPAP, and surgical improvement of the airway, including mid-face advancement. Otolaryngologic manifestations are also common. Respiratory failure due to small thoracic volumes is reported, but uncommon. Mortality rate at all ages was 2.27 (CI: 1.7-3.0) with age-specific mortality increased at all ages. Sudden death was most common in infants and children. Cardiovascular events are the main cause of mortality in adults. Despite earlier recognition and treatment of respiratory complications of achondroplasia, increased mortality rates and other complications remain high. Future and ongoing evaluation of the prevalence and impact of respiratory disorders, particularly OSA, in achondroplasia is recommended. Crown Copyright © 2013. Published by Elsevier Ltd.

    2012-01-01

    Density has been reported as one of the most difficult concepts for secondary school students (e.g. Smith et al. 1997). Discussion about the difficulties of learning this concept has been largely focused on the complexity of the concept itself or student misconceptions. Few, if any, have investigated how the concept of density was constituted in…

    Our study aimed to determine how age- and disease-related difficulties were associated with attitudes and beliefs about driving self-regulation in men and women in the baby boomer and older generations. Three hundred and ninety-nine men (n=204) and women (n=195) aged between 48 and 91 years participated in a cross-sectional study of Australian drivers. Demographic characteristics and measures of driving confidence, driving difficulty and driving self-regulation; perceptions of visual, physical and cognitive capacity; and attitudes and beliefs about driving were obtained. Driving self-regulation in men and women was explained by different mechanisms. For men, self-report of visual and cognitive difficulties and poor driving confidence predicted driving self-regulation. For women, negative attitudes toward driving mediated the associations found between health-related difficulties and driving self-regulation. Barriers to driving self-regulation were not associated with the driving self-regulatory practices of men or women. Regardless of generation, women reported poorer driving confidence, greater driving difficulty and more driving self-regulation than men. We concluded that age- and disease-related difficulties are related to increasing driving self-regulation in mature men and women. These results indicate that different pathways are needed in models of driving self-regulation for men and women regardless of generational cohort. Copyright © 2017 Elsevier Ltd.

    Full Text Available Purpose—the focus of this article is to explore difficulties that are encountered by students during the first term at university. It is well known that students can have various problems in learning English and make mistakes in grammar, vocabulary, and pronunciation. The native language of a learner affects learning and using English. Speaking and e-listening are the skills that are more common on an everyday basis than reading and writing. Moreover, these skills are more difficult to master. English vocabulary presents another problem for language learners. Albeit, at the university level students study English for Specific Purposes (ESP, in other words, the foreign language for their future profession, and they might face particular difficulties in their studies of ESP. Design/methodology/approach—the research paper adopts the qualitative research approach. The questionnaire on learner perceptions of difficulties in e-learning was administered to students of three different specializations. Students’ self-assessments of achievements or failures were analysed. Findings. The results indicated that perceptions of difficulties to adapting to university studies depended on their chosen specialization. The findings show that undergraduates of all three investigated specializations encounter the same difficulties, but to a different degree. In other words, there are no significantly specific difficulties due to the complexity of the professional vocabulary that students must learn. The ratings of Psychology, Social Work and Public Policy and Management students reveal higher mean values and wider range of Standard Deviations than reported by other researchers (Berman, Cheng, 2001. The results obtained imply that Lithuanian learners are more positive than their foreign counterparts. Computations of Pearson’s correlations coefficients demonstrate that there are some good correlational relationships within each specialization. Research

    Swallowing difficulties are common and can affect patients' ability to take solid oral dosage forms, thus compromising medication adherence. Strategies developed by patients to overcome such difficulties while taking medicines have seldom been described. To determine prevalence and characteristics of swallowing difficulties among primary care patients attending their community pharmacies; to explore strategies developed by patients to overcome their difficulties, and health professionals' awareness of these problems. Prospective study with a semi-structured questionnaire in random community pharmacies located in two Swiss regions. In each pharmacy, an interviewer asked 16 questions to each consecutive patient (18 years and older) with a prescription for at least 3 different solid oral forms. Quantification of number of patients with swallowing difficulties and detailed description of difficulties. Among 122 pharmacies, 59 (48 %) accepted to join the study and 410 patients were enrolled. Thirty-seven patients (9.0 %) reported ongoing swallowing difficulties, while 55 patients (13.4 %) reported past difficulties. For the majority of patients, difficulties occurred at each single dose (83.7 %), with a single medication (59.8 %) and lasted for less than 12 months (53.8 %). Number of tablets was not the main trigger. Swallowing difficulties impaired extremely daily life in 12 % of the patients. Intentional non adherence (23 % of patients) and altering the oral dose formulation were the most common and potentially harmful strategies used by patients to overcome their swallowing difficulties. According to the patients, pharmacists and physicians rarely inquired about their swallowing difficulties. We report a fairly high prevalence of swallowing difficulties in polypharmacy patients attending their community pharmacies. Pharmacists have to interview patients on their swallowing difficulties in a more systematic way, support patients in finding solutions and refer them to

    In this study we tried to improve the erythromycin ethylsuccinate obtaining, having in view to separate the erythromycin ester by crystallization in water. The erythromycin acylation and the erythromycin ethylsuccinate crystallization were realized, following the next steps: 1. the acylation of the erythromycin with a methylene chloride solution of monoethylsuccinyl chloride, at 25-28 degrees C for 3 hours in the presence of NaHCO3; 2. the transfer of the erythromycin ethylsuccinate from methylene chloride solution in acetone solution by distillation of mixture methylene chloride: acetone 1:1 at 25-28 degrees C; 3. erythromycin ethylsuccinate separation by crystallization in water at pH = 8-8.5 and 5 degrees C for 90 minutes. The quality control for the erythromycin ester was performed according to the Xth edition of Romanian Pharmacopoeia standards using national standard for erythromycin ethylsuccinate and national standard for erythromycin with an activity of 1: 937 U and 2.02% humidity. The Micrococcus luteus ATCC 9341 was used as a test microorganism and a thin layer cromatography was performed for qualitative control. 13.1 g of erythromycin ethylsuccinate were obtained with an output of the process of 82.02%. Using water for the separation of erythromycin ethylsuccinate the output of the process is greater (82.02%) than in case of using petroleum ether (74.14%) or hexane (80.25%). The thin layer cromatography revealed an Rf = 0.56 and the microbiological activity of the erythromycin ethylsuccinate was 98.7% compared with the standard. Using water instead of hexane or petroleum ether is gainful for the separation of erythromycin ethylsuccinate from the reaction medium. The obtained erythromycin ethylsuccinate corresponds to the Xth edition of Romanian Pharmacopoeia standards. So, the raw materials consumption is decreased, the costs are cut down, the obtained product purity is high and the output of the process is greater.

    2017-03-01

    Full Text Available The objective of this article is to analyze some of the difficulties of academic writing at postgraduate level, reported in certain studies within the framework of the cognitive functions concept developed by Reuven Feuerstein and other works, which allow to evidence the possible relationship between these two phenomena. To do this, we explored the conceptual framework of cognitive functions and mental operations, based on the theory of Feuerstein, et al. (1994; later, it was performed a synthesis of the difficulties described by Carlino (2007, Slafer (2009 and Hernández (2009; finally, it was established evidence of the relationship between cognitive functions and difficulties in academic writing. The results show that the different difficulties evidenced in the writing processes at postgraduate level have their source in the cognitive deficits presented in each phase of the mental act (entry, elaboration and output. It is concluded that the difficulties in academic writing recorded in the studies have a close link with cognitive functions of the elaboration and output stages of thought, even though they are only associated with the input phase.

    2014-03-01

    A very important increase in the costs of the edition of scientific journals has taken place in Venezuela, due to difficulties in obtaining imported free acid paper and other materials used for handling documents. Like other journals, Investigaci6n Clinica has been considering switching completely to a digital publication format; however there are several reasons that prevent us to doing it at this time: the journal is distributed in printed form to many national institutions, which do not have immediate access to digital information. In addition, there exists a commitment of shipment of printed issues for some international indices and in exchange with other national and foreign journals, whose printed format we receive. Another important aspect is that our University maintains a weak technological platform that makes difficult the immediacy required for the interchange with authors and consulted referees of received papers; and there is a latent danger of limitations in the use of digital technologies, due to current national politic problems. Consequently, we need to continue with the printed format, but must reduce the amount of printed issues, so as not to limit the number of papers published in each edition. Nevertheless, there is an ever increasing number of contributions from foreign researches and Investigaci6n Clinica has been recently included in two new international indices, the SEIIC from Argentina and the Infobase Index from India, reasons that obligate us to maintain our levels of excellence and commitment to our authors and readers.

    Full Text Available Introduction: The lowered temporal meninges and/ or anterior sigmoid sinus are contiditions that can determine surgical difficulties in performing mastoidectomy. Objective: To correlate in the tomography the extent of the prolapse of the sigmoid sinus and of temporal meninges with the surgical difficulty in the mastoidectomy. Method: The tomographic measurements of prolapse sigmoid and of temporal meninges were correlated with the presence or non-presence of the surgical difficulty observed during the mastoidectomy procedure in patients with ostomatoiditis chronic (n=30. Form of study: Contemporary cohort transverse. Results: In 10 patients were observed surgical difficulty distributed as: due to prolapse of the sigmoid sinus (n = 2 or temporal meninges prolapse (n = 7 or both (n = 1. In patients in which the surgical difficulty was due to sigmoid sinus prolapse, the tomography distance of the anterior border of the sigmoid sinus to posterior wall of external auditory canal was lower than 9 mm. In patients in which surgical difficulty was due to temporal meninges prolapse, the tomographic distance to the upper plane of the petrous bone was 7 mm. Conclusion: The computerized tomography distance between the temporal meninges and the upper plane of the petrous bone 7 mm and the distance of the anterior border of the sigmoid sinus to posterior wall of external auditory canal was lower than 9 mm are predictive to the surgical difficulties to perform mastoidectomy.

    Full Text Available In research we investigated the difficulties faced by Slovenian high school students when choosing a university programme. A theoretical taxonomy of career decision making difficulties proposed by Gati, Krausz and Osipow was examined with Career decision making difficulties Questionnaire which was translated into Slovenian language and adapted to the context of choosing a university programme. The questionnaire was administrated to a sample of 179 fourth grade high school students. The results showed that students in general face small to medium difficulties when choosing a university programme. They have the greatest difficulties in the fields of general indecisiveness, disfunctional beliefs, and lack of information about existing university programmes, and the smallest in the fields of external conflicts and lack of motivation. In general there were no important differences in difficulties between boys and girls. The exception was the field of lack of motivation, where girls reported fewer difficulties than boys. Determined students reported fewer difficulties than undetermined. When comparing the empirical structure of high school students' difficulties when choosing the university programme to theoretical taxonomy of career decision making difficulties, we found more differences than similarities.

    The aims of the present study were to investigate whether being subjected to bullying and witnessing bullying at the workplace was associated with concurrent sleep difficulties, whether frequently bullied/witnesses have more sleep difficulties than occasionally bullied/witnesses, and whether there were associations between being subjected to bullying or witnessing bullying at the workplace and subsequent sleep difficulties. A total of 3,382 respondents (67 % women and 33 % men) completed a baseline questionnaire about their psychosocial work environment and health. The overall response rate was 46 %. At follow-up 2 years later, 1671 of those responded to a second questionnaire (49 % of the 3,382 respondents at baseline). Sleep difficulties were measured in terms of disturbed sleep, awakening problems, and poor quality of sleep. Bullied persons and witnesses reported more sleep difficulties than those who were neither bullied nor witnesses to bullying at baseline. Frequently bullied/witnesses reported more sleep difficulties than respondents who were occasionally bullied or witnessing bullying at baseline. Further, odds ratios for subsequent sleep difficulties were increased among the occasionally bullied, but not among witnesses. However, the associations weakened when adjusting for sleep difficulties at baseline. Being subjected to occasional bullying at baseline was predictive of subsequent sleep difficulties. Witnessing bullying at baseline did not predict sleep difficulties at follow-up.

    2016-01-01

    We discuss an investigation exploring students' difficulties with equations involving resistance, capacitance and inductance. We find that introductory physics students have great difficulty understanding, e.g., how the resistance of an ohmic resistor can be written in terms of the potential difference across it and the current through it, but it does not change when the potential difference across the resistor is varied. Similar confusions arose in problems relating to capacitors and inductors. We discuss these difficulties with equations in the context of introductory physics students' performance on questions about circuit elements both in the free-response and multiple-choice formats.

    2010-06-01

    Full Text Available We aimed, along the text, to bring a reflection upon learning difficulties based on Socio-Historical Theory, relating what is observed in schools to what has been discussed about learning difficulties and the theory proposed by Vygotsky in the early XX century. We understand that children enter school carrying experiences and knowledge from their cultural group and that school ignores such knowledge very often. Then, it is in such disengagement that emerges what we started to call learning difficulties. One cannot forget to see a child as a whole – a student is a social being constituted by culture, language and specific values to which one must be attentive.

    2012-12-01

    Feeding difficulties are common in children with cerebral palsy and have an effect on growth, nutritional state, general health, social interaction and behaviour and developmental outcomes. Many factors have an effect on feeding ability. Identification of these factors and amelioration of their impact on feeding difficulties is essential to promote adequate growth and nutrition. Appropriate assessment and management is best achieved by a multiprofessional team skilled in the care of children with cerebral palsy and feeding impairments. Feeding difficulties must be considered within the wider context of family and social circumstance.

    Many students enrolled in introductory mechanics courses have difficulties with understanding the concept of static equilibrium. Some of these difficulties are related to the concept of force in the context of tension in massless strings. We identify three kinds of misconceptions: Students' beliefs that the angle of the string and proximity to the object are related to the tension. Students also use incorrect compensation arguments to reason about situations where both the angle and proximity change simultaneously. These difficulties were identified during investigations conducted in laboratory and lecture sessions at three universities in the United States and Mexico.

    Full Text Available Abstract Background Difficulty sleeping is common among patients with fibromyalgia (FM; however, its impact on health-related quality of life (HRQoL is not well understood. The aim of the current study was to assess the burden of sleep difficulty symptoms on HRQoL among patients with FM. Methods The current study included data from the 2009 National Health and Wellness Survey (N=75,000, which is a cross-sectional, Internet-based survey representative of the adult US population. The prevalence of sleep difficulty symptoms among patients with FM (n=2,196 were compared with matched controls (n=2,194, identified using propensity-score matching. Additionally, the relationship between the number of sleep difficulty symptoms (none, one, or two or more and HRQoL (using the SF-12v2 was assessed using regression modeling, controlling for demographic and health history variables. Results Of the 2,196 patients with FM, 11.2% reported no sleep difficulty symptoms, 25.7% reported one sleep difficulty symptom, and 63.05% reported two or more sleep difficulty symptoms. The prevalence of sleep difficulty symptoms was significantly higher than matched controls. Patients with one and two sleep difficulty symptoms both reported significantly worse HRQoL summary and domain scores relative to those with no sleep difficulty symptoms (all p Conclusions Among the FM population, sleep difficulty symptoms were independently associated with clinically-meaningful decrements in mental and physical HRQoL. These results suggest that greater emphasis in the treatment of sleep difficulty symptoms among the FM population may be warranted.

    Full Text Available For several years now, noticeable has been a significant increase in the interest of psychologists – practitioners and scientists, of parents and teachers in the issues of dyslexia, dyscalculia, and other developmental disorders. Specific learning difficulties constitute one of the most prevalent causes of reporting children to psychological and pedagogic outpatient departments. The results of the performed studies enable inter- and intra-group comparisons as well as a global analysis of the structure of intellectual development in children with various learning difficulties. This leads to interesting conclusions and allows for comprehensive scientific discussions. The subject of the article is presentation of the results of studies and conclusions formulated according to them, about the structure of intellectual development of children with learning difficulties diagnosed in two psychological-pedagogic outpatient departments in Lublin region (Psychological-Pedagogic Outpatient Department No 5 in Lublin and PsychologicalPedagogic Outpatient Department No 2 in Zamość. Analysed were the results of the WISC-R scale obtained by schoolchildren from forms IV-VI of elementary schools and junior secondary schools in Lublin and schools of Zamość county. As scholastic difficulties constitute quite a comprehensive term, generally perceived as problems in acquisition of information and mastering school skills, in our study we take into account the following three groups of schoolchildren: with developmental dyslexia, intelligence lower than average, and specific disorders in arithmetic skills. The performed analyses are aimed at familiarization with the developmental level of the schoolchildren’s cognitive functions and their intellectual skills structure based on a three-factor analysis. Our studies continue earlier analyses, including more comprehensive research areas with larger groups.

    To describe assistance from helpers and use of assistive technology and environmental modification by community-dwelling people with difficulties in activities of daily living (ADLs) and instrumental activities of daily living (IADLs). Cross-sectional study using the 2004 Medicare Current Beneficiary Survey. Community. Nationally representative sample of 14,500 Medicare beneficiaries (mean age, 71.5 y; 55% female; 49% currently married; 68% living with others; 84% white). Not applicable. Self-reported difficulty with ADLs and IADLs; uses of help, assistive technology, and/or environmental modification. Difficulties were reported most frequently for heavy housework, walking, and shopping; money management, shopping, and light housework were reported as activities most often needing a helper. Walking, bathing, and toileting were activities most often needing uses of assistive technology. Bathroom modifications were the most commonly reported environmental modification. Results from a logistic regression showed that advancing age was the primary factor associated with increasing use of helpers and assistive technology or both for difficult activities. Uses of helpers, assistive technology, and environmental modification are common but vary by type of ADL and/or IADL and age. Focused studies regarding uses of help and access to assistive technology and environmental modification appear needed to support community living. Public education about methods and types of accommodations appears needed and may substitute for or augment guidance from care providers.

    A qualitative approach was used to interview 23 Sudanese refugees residing in Brisbane, Australia. Semi-structured interviews were conducted to examine the participants' pre-migration, transit and post-migration experiences. Refugees reported traumatic and life-threatening experiences during the pre-migration and transit phases, and difficulties with resettlement during the post-migration phase. Nevertheless, participants reported using a number of coping strategies across all phases, including: reliance on religious beliefs, cognitive strategies such as reframing the situation, relying on their inner resources, and focusing on future wishes and aspirations. Social support also emerged as a salient coping strategy. The findings are useful for mental health professionals as they highlight the difficulties experienced by refugees across phases of migration as well as strategies they use to manage these traumas and stresses.

    Wellness of people with mental illness is increasingly a public health priority. This study examined factors associated with difficulties receiving medical care in adults with mental illness. In a sample of 1,670 adults with mental illness, we assessed difficulties in accessing medical care and stigma. A total of 465 (28%) participants reported difficulties in accessing medical care; 211 (13%) attributed difficulties in access to stigma. Lack of comprehensive medical care coverage and mental health symptoms were associated with increased odds of perceived difficulties in accessing medical care; personal empowerment was negatively associated with perceived difficulties attributed to stigma; education was positively associated. The findings highlight unmet need for medical care in this population and the need to recognize stigma as a barrier medical care. Interventions to empower patients and educate medical providers about wellness for people with serious mental illness could help to reduce barriers.

  9. Identifying predictors of physics item difficulty: A linear regression approach

    Full Text Available Large-scale assessments of student achievement in physics are often approached with an intention to discriminate students based on the attained level of their physics competencies. Therefore, for purposes of test design, it is important that items display an acceptable discriminatory behavior. To that end, it is recommended to avoid extraordinary difficult and very easy items. Knowing the factors that influence physics item difficulty makes it possible to model the item difficulty even before the first pilot study is conducted. Thus, by identifying predictors of physics item difficulty, we can improve the test-design process. Furthermore, we get additional qualitative feedback regarding the basic aspects of student cognitive achievement in physics that are directly responsible for the obtained, quantitative test results. In this study, we conducted a secondary analysis of data that came from two large-scale assessments of student physics achievement at the end of compulsory education in Bosnia and Herzegovina. Foremost, we explored the concept of “physics competence” and performed a content analysis of 123 physics items that were included within the above-mentioned assessments. Thereafter, an item database was created. Items were described by variables which reflect some basic cognitive aspects of physics competence. For each of the assessments, Rasch item difficulties were calculated in separate analyses. In order to make the item difficulties from different assessments comparable, a virtual test equating procedure had to be implemented. Finally, a regression model of physics item difficulty was created. It has been shown that 61.2% of item difficulty variance can be explained by factors which reflect the automaticity, complexity, and modality of the knowledge structure that is relevant for generating the most probable correct solution, as well as by the divergence of required thinking and interference effects between intuitive and formal

    2014-12-01

    Within mathematics curricula, algebra has been widely recognized as one of the most difficult topics, which leads to learning difficulties worldwide. In Indonesia, algebra performance is an important issue. In the Trends in International Mathematics and Science Study (TIMSS) 2007, Indonesian students' achievement in the algebra domain was significantly below the average student performance in other Southeast Asian countries such as Thailand, Malaysia, and Singapore. This fact gave rise to this study which aims to investigate Indonesian students' difficulties in algebra. In order to do so, a literature study was carried out on students' difficulties in initial algebra. Next, an individual written test on algebra tasks was administered, followed by interviews. A sample of 51 grade VII Indonesian students worked the written test, and 37 of them were interviewed afterwards. Data analysis revealed that mathematization, i.e., the ability to translate back and forth between the world of the problem situation and the world of mathematics and to reorganize the mathematical system itself, constituted the most frequently observed difficulty in both the written test and the interview data. Other observed difficulties concerned understanding algebraic expressions, applying arithmetic operations in numerical and algebraic expressions, understanding the different meanings of the equal sign, and understanding variables. The consequences of these findings on both task design and further research in algebra education are discussed.

    The optimal age for assessing language difficulties in premature children remains unclear. To determine the most predictive and earliest screening tool for later language difficulties on children born preterm. A prospective population-based study in the Loire Infant Follow-up Team LIFT SUBJECTS: All children born language items of Brunet Lezine test at 24months, and the "Epreuves de Repérage des Troubles du Langage" (ERTL) at 4years. After 5years, the kindergarten teacher evaluated the vocabulary, grammar and pronunciation capacities of the child in comparison with the classroom performances. Among 1957 infants enrolled at discharge, 947 were assessed by their teacher with 12.2% (n=116) of language difficulties. Full data at all time points were available for 426 infants. The area under curve of the receiver operator characteristic curve obtained for the ASQ communication scale at 18months was significantly lower (0.65±0.09) than that obtained at 24months (0.77±0.08) and the languages items of Brunet Lezine test at 24months (0.77±0.08), and the ERTL at 4years (0.76±0.09). The optimal cut-off value for ASQ communication at 24months is ≤45 [sensitivity of 0.79 (95%CI: 0.70-0.86); specificity of 0.63 (95%CI: 0.59-0.66)]. The Ages & Stages Questionnaire communication scale at 24 corrected months appears as an acceptable test at an early time point to identify preterm children at risk of later language difficulties.

    Increased childhood adversity may be affect adult fertility, however, the mechanism through which this occurs is unclear. Menstrual cycle abnormalities are predictive of fertility difficulties, and stress influences menstrual cycle characteristics. Here, we assess whether adverse childhood experiences (ACEs) are associated with fertility difficulties and menstrual cycle dysregulation, offering a plausible mechanism for the link between lifetime stress and fertility. From April 2012 to February 2014, 742 pregnant and non-pregnant women aged 18-45 years residing in southeastern Louisiana provided information on childhood adversity and reproductive history. Associations between ACEs and fertility difficulties and menstrual cycle patterns were evaluated. As the number of ACEs increased, risk of fertility difficulties and amenorrhea increased (RR = 1.09, 95% CI 1.05-1.13 and RR = 1.07, 95% CI 1.04-1.10, respectively), while fecundability decreased [fecundability ratio (FR) = 0.97, 95% CI 0.95-1.00]. Compared to women with no adversity, women in the high adversity group were more likely to experience both infertility and amenorrhea (RR = 2.75, 95% CI 1.45-5.21 and RR = 2.54, 95% CI 1.52-4.25, respectively), and reduced fecundability (FR = 0.75, 95% CI 0.56-1.00). Although similar patterns were seen for menstrual cycle irregularity, associations were diminished. Associations did not materially change following adjustment for age, body mass index, race, education, smoking and income. Results are constrained by the self-report nature of the study and the limited generalizability of the study population. To our knowledge, this is the first study to present evidence of a link between childhood stressors, menstrual cycle disruption and fertility difficulties. The effect of childhood stress on fertility may be mediated through altered functioning of the HPA axis, acting to suppress fertility in response to less than optimal reproductive circumstances.

    Most of the children having Specific Language Impairment (SLI) exhibit pragmatic difficulties that are often overlooked while their communication skills are being evaluated. Identifying pragmatic needs in such children can be lengthy and indeterminate as many of such children don't quite "fit" into a definite diagnostic category. This study aimed at identifying and clarifying the nature of pragmatic difficulties in a group of children with Specific Language Impairment by comparing their pragmatic skills with those of a group of normally developing children using a simple Pragmatic Screening protocol hoping that this would aid in reaching a better understanding of the nature of pragmatic difficulties in such children. The present study examined the pragmatic profiles of 60 age and gender matched native Cairo-Egyptian Arabic speaking children (with age range 4-6 years old). The children were divided into two groups; Group A and Group B. Group A included 30 children with normal language development whereas Group B included 30 children who had been previously diagnosed as having Specific Language Impairment. For each subject, history taking followed by audiological and psychometric evaluation to rule out the existence of any hearing difficulties or mental deficiency was performed. Afterwards, each child under study was subjected to the Arabic Pragmatic Screening tool [1]. For each child, the screening was scored by three readers; average scores were obtained and statistically analyzed. All the values obtained by the control group were found to be significantly higher than those obtained by the SLI group except for some non-verbal paralinguistic skills where non-significant differences were found between the two groups. Through the ROC curve, cut off level for Total Pragmatic Score (TPS) was found to be less than or equal to 78.16, i.e. 4-6 year old children with a TPS equal to or less than 78.16 were considered to have pragmatic difficulties.

    Although gait and balance difficulties often occur together in Parkinson's disease (PD) patients, it is believed that they are actually two eparate symptoms. However, there are no simple tests to distinguish them. We have developed the self-administered Barrow Neurological Institute (BNI) question to distinguish between gait and balance issues in PD and it was tested in 102 consecutive PD patients. The responses were compared with those of the walking and balance question (item # 2.12) of the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS), and the MDS-UPDRS motor examination and its subsets such as gait and postural stability (PS). Fifty-five patients reported balance difficulty on the BNI question and 64 reported walking and balance difficulty on the MDS-UPDRS question. Of the patients who reported balance difficulty on the BNI question, 74.5% had a PS score ≥2 and 25.4% fell at least three times per month. Of the patients who reported walking and balance difficulty on the MDS-UPDRS question, only 59.4% had a PS score ≥2 and only 10.9% fell three or more times per month. These statistically significant results suggest that the BNI question is better able to detect balance difficulty and its associated falls in PD and can be a supplement to the MDS-UPDRS or a stand-alone question to evaluate balance difficulty and its associated falls in PD.

    Full Text Available Objective. Report prevalence of functioning difficulties and disabilities among Mexican adolescent women 15-17 years old and identify differences in characteristics of those with and without a functioning difficulty or disability Materials and methods. Using data from the National Survey of Boys, Girls and Women in Mexico 2015 we estimated prevalence of functioning difficulties and disability and used chi square tests for independence and logistic regression to explore associations between this condition and various characteristics. Results. Of Mexican adolescent women 15-17 years old, 11.1% had a functioning difficulty or disability. The group of domains of functioning difficulty and disability with by far the highest prevalence was socio-emotional and behavioral functioning difficulties or disability with 8.6%. Being employed, rural residence and self-reported depression symptoms were associated with having functioning difficulties or disability. Conclusions. This survey constitutes an important initial step in collecting data on functioning difficulty and disability in Mexico although larger samples should be studied.

    Full Text Available Contemporary psychological and pedagogical studies pay special attention to the socialization of physically impaired children, inclusive education and methods of providing such children with a safe environment to assist in their development. However, difficulties in interpersonal communication experienced by children with health impairments have remained beyond the research scope. The authors conducted a comparative analysis of communication difficulties in typically developed teenagers aged 12-13 years (n = 100 and the problems faced by their peers with visual (n = 30, auditory (n = 30, speech (n = 25 and motor (n = 15 impairments. Actual communication difficulties in teenagers were studied in two ways: the subjective component of impaired communication was registered through a content analysis of a sentence completion test and the objective manifestations of impaired communication were identified through expert evaluation of children’s communicative behavior (educators and psychologists who had been in close contact with the teenagers acted as experts. First, the authors identified typical standard communication problems that were characteristic of teenagers aged 12-13 years, that is, problems with aggression, tolerance, the ability to admit wrongdoing and make concessions, empathy, self-control, self-analysis and self-expression in communication. Second, typical communication difficulties characteristic of physically impaired children were revealed: failure to understand meaning; feelings of awkwardness and shame of oneself; expectations of a negative attitude toward oneself; gelotophobia; and manifestations of despotism, petulance and egotism as defensive reactions in situations of impaired communication. Third, the authors described specific communication difficulties in teenagers with auditory, visual, speech and motor impairments.

    Reading is a multi-sensory and multi-cognitive task, and its difficulties (e.g., dyslexia) are not a unitary disorder. There are probably a variety of manifestations that relate to the actual site of impairment. A randomized, pre-test/post-test nonequivalent-groups design was conducted over 4 months with three groups aged between 6 and 8 years. One group comprised 76 participants (34 boys, 42 girls) with reading difficulties and altered sensory fusion (RD+ASF), a second group was made up of 123 students (59 boys, 64 girls) with reading difficulties but without altered sensory fusion (RD), and a third group comprised 81 participants (39 boys, 42 girls) who were young readers (RL) without reading delay, paired with the RD group on reading level. The experimental groups received intervention in the skills of control, stimulus recognition, and phonological awareness during a 4-month period. Both pre-test and post-test measures of errors in reading mechanics and reading routes (word and pseudo-word) were obtained. Poorer results in mechanics and reading routes of the RD+ASF group suggest that the effectiveness of the intervention depended on the characteristics of the groups and on the presence of sensory fusion deficits in the RD students.

  7. Adjusting game difficulty level through Formal Concept Analysis

    Gómez-Martín, Marco A.; Gómez-Martín, Pedro P.; Gonzâlez-Calero, Pedro A.; Díaz-Agudo, Belén

    In order to reach as many players as possible, videogames usually allow the user to choose the difficulty level. To do it, game designers have to decide the values that some game parameters will have depending on that decision. In simple videogames this is almost trivial: minesweeper is harder with longer board sizes and number of mines. In more complex games, game designers may take advantage of data mining to establish which of all the possible parameters will affect positively to the player experience. This paper describes the use of Formal Concept Analysis to help to balance the game using the logs obtained in the tests made prior the release of the game.

    There has been a growing interest in developing behavioral tasks to enhance temporal acuity as recent findings have demonstrated changes in temporal processing in a number of clinical conditions. Prior research has demonstrated that perceptual training can enhance temporal acuity both within and across different sensory modalities. Although certain forms of unisensory perceptual learning have been shown to be dependent upon task difficulty, this relationship has not been explored for multisensory learning. The present study sought to determine the effects of task difficulty on multisensory perceptual learning. Prior to and following a single training session, participants completed a simultaneity judgment (SJ) task, which required them to judge whether a visual stimulus (flash) and auditory stimulus (beep) presented in synchrony or at various stimulus onset asynchronies (SOAs) occurred synchronously or asynchronously. During the training session, participants completed the same SJ task but received feedback regarding the accuracy of their responses. Participants were randomly assigned to one of three levels of difficulty during training: easy, moderate, and hard, which were distinguished based on the SOAs used during training. We report that only the most difficult (i.e., hard) training protocol enhanced temporal acuity. We conclude that perceptual training protocols for enhancing multisensory temporal acuity may be optimized by employing audiovisual stimuli for which it is difficult to discriminate temporal synchrony from asynchrony.

    This study drew on the relational turbulence model to investigate how the interpersonal dynamics of military couples predict parents' reports of the reintegration difficulty of military children upon homecoming after deployment. Longitudinal data were collected from 118 military couples once per month for 3 consecutive months after reunion. Military couples reported on their depressive symptoms, characteristics of their romantic relationship, and the reintegration difficulty of their oldest child. Results of dyadic growth curve models indicated that the mean levels of parents' depressive symptoms (H1), relationship uncertainty (H2), and interference from a partner (H3) were positively associated with parents' reports of military children's reintegration difficulty. These findings suggest that the relational turbulence model has utility for illuminating the reintegration difficulty of military children during the postdeployment transition.

    This study examined victimisation, substance misuse, relationships, sexual activity, mental health difficulties and suicidal behaviour among adolescents with sexual orientation concerns in comparison to those without such concerns. 1112 Irish students (mean age 14 yrs) in 17 mixed-gender secondary schools completed a self-report questionnaire with standardised scales and measures of psychosocial difficulties. 58 students (5%) reported having concerns regarding their sexual orientation. Compared with their peers, they had higher levels of mental health difficulties and a markedly-increased prevalence of attempted suicide (29% vs. 2%), physical assault (40% vs. 8%), sexual assault (16%vs. 1%) and substance misuse. Almost all those (90%) with sexual orientation concerns reported having had sex compared to just 4% of their peers. These results highlight the significant difficulties associated with sexual orientation concerns in adolescents in Ireland. Early and targeted interventions are essential to address their needs.

    Children who have experienced deprivation as a result of orphanage care during early development are at increased risk for a number of cognitive, emotional, and social difficulties (MacLean, 2003). This study examined the neuropsychological and behavioral profile of internationally adopted children with language difficulties, one of the most common cognitive challenges (Behen et al., 2008). In addition to neuropsychological testing, fMRI was utilized to examine activation patterns during expressive fluency and receptive language tasks. In comparison to internationally adopted children without language difficulties and nonadopted controls, participants with language difficulty had worse performance on tasks of verbal memory and reasoning, academic skills, and working memory. Behaviorally, all internationally adopted participants, regardless of language ability, had more parent-reported hyperactivity and impulsivity compared with controls. The fMRI tasks revealed reduced activation in traditional language areas in participants with language difficulty. The impact of early adverse experience on later development is discussed.

  12. Student Difficulties with the Dirac Delta Function

    2014-01-01

    The Dirac delta function is a standard mathematical tool used in multiple topical areas in the undergraduate physics curriculum. While Dirac delta functions are usually introduced in order to simplify a problem mathematically, students often struggle to manipulate and interpret them. To better understand student difficulties with the delta function at the upper-division level, we examined responses to traditional exam questions and conducted think-aloud interviews. Our analysis was guided by an analytical framework that focuses on how students activate, construct, execute, and reflect on the Dirac delta function in physics. Here, we focus on student difficulties using the delta function to express charge distributions in the context of junior-level electrostatics. Challenges included: invoking the delta function spontaneously, constructing two- and three-dimensional delta functions, integrating novel delta function expressions, and recognizing that the delta function can have units.

  13. Students’ difficulties with integration in electricity

    2011-06-01

    Full Text Available This study investigates the common difficulties that students in introductory physics experience when solving problems involving integration in the context of electricity. We conducted teaching-learning interviews with 15 students in a second-semester calculus-based introductory physics course on several problems involving integration. We found that although most of the students could recognize the need for an integral in solving the problem, they failed to set up the desired integral. We provide evidence that this failure can be attributed to students’ inability to understand the infinitesimal term in the integral and/or failure to understand the notion of accumulation of an infinitesimal physical quantity. This work supports and extends previous research on students’ difficulties with integration in physics.

    Full Text Available Patients with deep neck infections present challenging airways for an anesthesiologist . Ludwig’s angina is potentially lethal, rapidly spreading cellulitis involving the floor of the mouth and neck. Without aggressive management it often results in life th reatening upper airway obstruction. Securing the airway remains the top priority in treatment of Ludwig’s angina. Although awake fibreoptic intubation remains the ideal method for securing the airway, but it is not available in every set up, so all feasibl e options of securing the airway should be prepared. We present a case successfully managed at our hospital with a brief review of airway management options.

    1999-01-01

    Genital actinomycosis is a rare bacterial infection affecting women of child-bearing age, which is sometimes related to the use of an IUD or an intra-vaginal pessary. Nevertheless, this relationship is at best tenous and actinomycosis is not the only bacterial infection caused by IUD use. Genital actinomycosis often occurs as a pelvic tumour which is sometimes difficult to correctly diagnose and consequently treat accordingly. Rapid diagnosis is essential in order to avoid any irreparable tissue damage. Treatment of this condition consists of a combination of antibiotics and surgery to achieve complete recovery. Three cases are described.

  20. ERRORS AND DIFFICULTIES IN TRANSLATING LEGAL TEXTS

    Directory of Open Access Journals (Sweden)

    Camelia, CHIRILA

    2014-11-01

    Full Text Available Nowadays the accurate translation of legal texts has become highly important as the mistranslation of a passage in a contract, for example, could lead to lawsuits and loss of money. Consequently, the translation of legal texts to other languages faces many difficulties and only professional translators specialised in legal translation should deal with the translation of legal documents and scholarly writings. The purpose of this paper is to analyze translation from three perspectives: translation quality, errors and difficulties encountered in translating legal texts and consequences of such errors in professional translation. First of all, the paper points out the importance of performing a good and correct translation, which is one of the most important elements to be considered when discussing translation. Furthermore, the paper presents an overview of the errors and difficulties in translating texts and of the consequences of errors in professional translation, with applications to the field of law. The paper is also an approach to the differences between languages (English and Romanian that can hinder comprehension for those who have embarked upon the difficult task of translation. The research method that I have used to achieve the objectives of the paper was the content analysis of various Romanian and foreign authors' works.

  1. DIFFICULTY OF AMENDMENT AND INTERPRETATIVE CHOICE

    Directory of Open Access Journals (Sweden)

    Andrew Coan

    2016-01-01

    Full Text Available The extreme difficulty of amending the U.S. Constitution plays a central but largely unexamined role in theoretical debates over interpretive choice. In particular, conventional wisdom assumes that the extreme difficulty of Article V amendment weakens the case for originalism. This view might ultimately be correct, but it is not the freestanding argument against originalism it is often presumed to be. Rather, it depends on contestable normative and empirical premises that require defense. If those premises are wrong, the stringency of Article V might actually strengthen the case for originalism. Or Article V might have no impact on that case one way or another. This “complexity thesis” highlights and clarifies the role that difficulty of amendment plays across a range of significant interpretive debates, including those surrounding writtenness, John Hart Ely’s representation-reinforcement theory, interpretive pluralism, and originalism as a theory of positive law. It also has important implications for the under-studied relations between statutory and constitutional interpretation and federal and state constitutional interpretation.

  2. 'Theory of mind' II: Difficulties and critiques.

    Science.gov (United States)

    Plastow, Michael

    2012-08-01

    'Theory of mind' will be further examined firstly by looking at the experimental situation that was used to put forward this notion. A fundamental difficulty regarding the failure of 'theory of mind' to account for the misunderstandings of everyday life will be discussed. Other difficulties in the experimental conceptualisation of this notion will then be studied. Critiques that have previously been made of 'theory of mind' will also be examined. 'Theory of mind' proposes an ideal of limpid understanding of the other. It is argued here that this notion of mind-reading is belied by its failure in our everyday lives. The experimental results by which this notion was proposed are neither sensitive nor specific. It is argued that there is also a fundamental error in this conception and its experimental design due to assessing a second-person phenomenon by a third-person method. Critiques of 'theory of mind' emphasise the epistemological difficulties and the fact that it is a poor explanation for the interactions of non-autistic subjects.

    2011-01-01

    People with communication impairments may face barriers to civic participation, with resulting marginalisation of individuals who wish to be actively involved. The investigation aimed to explore the experience of civically engaged adults with acquired neurological communication difficulties. Six people with acquired neurological communication difficulties were interviewed. Discussion included the definition of active citizenship, their civic involvement, motivations, related barriers and facilitators. Qualitative analysis was undertaken, with data categorised, coded and examined for recurring themes. All participants were active in disability-related organisations and four undertook wider civic roles. Motivations included activity being out with the home and wanting to effect change for themselves and the populations they represented. Disability group meetings were more positive experiences than broader community activities, which were associated with fatigue and frustration, commonly resulting from communication difficulties and unmet support needs. All participants identified a need for professional and public educational about disability and communication and made recommendations on content, methods and priority groups. For these participants civic engagement had positive and negative dimensions. Speech and language therapists should promote reduction of the barriers that impede the active citizenship rights of people with communication support needs. Civic participation may be a relevant measure of outcome in communication impaired populations.

  4. Phonetic difficulty and stuttering in English.

    Science.gov (United States)

    Howell, Peter; Au-Yeung, James; Yaruss, J Scott; Eldridge, Kevin

    2006-11-01

    Previous work has shown that phonetic difficulty affects older, but not younger, speakers who stutter and that older speakers experience more difficulty on content words than function words. The relationship between stuttering rate and a recently-developed index of phonetic complexity (IPC, Jakielski) was examined in this study separately for function and content words for speakers in 6-11, 11 plus-18 and 18 plus age groups. The hypothesis that stuttering rate on the content words of older speakers, but not younger speakers, would be related to the IPC score was supported. It is argued that the similarity between results using the IPC scores with a previous analysis that looked at late emerging consonants, consonant strings and multiple syllables (also conducted on function and content words separately), validates the former instrument. In further analyses, the factors that are most likely to lead to stuttering in English and their order of importance were established. The order found was consonant by manner, consonant by place, word length and contiguous consonant clusters. As the effects of phonetic difficulty are evident in teenage and adulthood, at least some of the factors may have an acquired influence on stuttering (rather than an innate universal basis, as the theory behind Jakielski's work suggests). This may be established in future work by doing cross-linguistic comparisons to see which factors operate universally. Disfluency on function words in early childhood appears to be responsive to factors other than phonetic complexity.

    Using everyday technology (ET) is a prerequisite for activities and participation at home and in the community. It is well known that persons with an acquired brain injury (ABI) can have limitations in activities of daily living but our knowledge of their difficulties using ET is not known. Thirty-six persons (27 men and 9 women, mean age 44 years, age range 26-60) with an ABI (2-10 years post injury) were interviewed, using the Everyday Technology Use Questionnaire (ETUQ), about their perceived difficulties using ET and how these difficulties influenced their everyday activities and their possibilities to participate at home and in the community. A majority (78%) of the persons reported difficulties using ET. The most common difficulties were related to the use of telecommunication and computers. Despite these difficulties, a majority still used most objects and services independently. Twenty-six participants (72%) perceived that their difficulties using ET influenced their everyday activities and their possibility to participate at home and in the community. The results indicate that rehabilitation following an ABI should consider whether clients' use of ET influences their activity and participation and adopt interventions accordingly. The results also indicate that difficulties using ET need to be considered in the design of community services to prevent societal barriers.

    2015-09-01

    The aim of the current study was to examine the direct and interactive effects of two types of narcissism (overt and covert) and respiratory sinus arrhythmia (RSA) reactivity on emotion regulation difficulties in 227 undergraduate students. Overt and covert narcissism and emotion regulation difficulties were assessed with self-report measures (narcissistic personality inventory (NPI)-16, hypersensitive narcissism scale (HSNS), and difficulties in emotion regulation scale (DERS)), and physiological data were measured during the baseline, stress (a public-speaking task), and recovery periods in the laboratory. Results indicated that overt narcissism was negatively related to a lack of emotional awareness and emotional clarity, whereas covert narcissism was positively related to overall emotion regulation difficulties, nonacceptance of emotional responses, impulse control difficulties, limited access to emotion regulation strategies, and a lack of emotional clarity. RSA reactivity in response to a mock job interview moderated the associations between covert narcissism (as a predictor) and overall emotion regulation difficulties and impulse control difficulties (as outcomes). This finding showed that a greater stress-induced RSA decrease may serve as a protective factor and ameliorate the effect of covert narcissism on individuals' emotion regulation difficulties.

    2013-02-01

    Full Text Available Close This study investigated teachers' perspectives of difficulties students have solving mathematical word problems and causes of those difficulties. Classroom practices and strategies teachers used in their attempts to foster student problem solving success were also studied. Participants were 70 second-fifth grade teachers from 42 different schools in a south central region of the United States. Data included analyses of interview transcriptions of teachers' responses. Findings from teachers' responses showed students' abilities to read and understand the problem was the most frequently cited difficulty; standardized testing and text difficulties were the most cited causes of those difficulties. Examination of teachers' responses to practices and strategies used in the classroom revealed the most cited practice was working the problem independently and the most cited strategy taught to students was to identify key words. This study revealed the significant role reading plays in teachers' perspectives of students' difficulties solving mathematical word problems and provided insight into practices and strategies teachers reported using to teach word problems. With attention to teacher-reported causes of difficulties and importance of this ability for students, this study also showed the impact state mandated testing has on instruction of mathematical word problems

    2017-01-01

    Fear of falling is associated with self-imposed restrictions of basic and instrumental activities of daily living (ADL/IADL), leading greater risk for functional decline and falls. The inability to independently grocery shop, a food-related IADL, negatively affects nutritional status and survival among seniors. Thus, this study examined the relationship between the fear of falling and difficulty with grocery shopping among seniors (n=98, mean age=82, 83% female), taking into account their functional capacity. Demographic profile, eating problems, physical fitness (mobility, balance, endurance, leg strength), and fear of falling (balance confidence, falls efficacy) were measured. Fifty-six percent of participants reported difficulty with grocery shopping. Those who reported difficulty had significantly lower scores for dynamic balance, balance confidence and fall efficacy compared to those who did not. This study revealed a relationship between the fear of falling and perceived difficulty with grocery shopping. Interventions should address fear of falling among the frail seniors.

    Anal fistula surgery is a commonly performed procedure. The diverse anatomy of anal fistulae and their proximity to anal sphincters make accurate preoperative diagnosis essential to avoid recurrence and fecal incontinence. De-spite the fact that proper preoperative diagnosis can be reached in the majority of patients by simple clinical ex-amination, endoanal ultrasound or magnetic resonance imaging, on many occasions, unexpected findings can be encountered during surgery that can make the oper-ation difficult and correct decision-making crucial. In this article we discuss the difficulties and unexpected find-ings that can be encountered during anal fistula sur-gery and how to overcome them.

    Full Text Available Abstract Background Previous health research has often explicitly excluded individuals from minority ethnic backgrounds due to perceived cultural and communication difficulties, including studies where there might be language/literacy problems in obtaining informed consent. This study addressed these difficulties by developing audio-recorded methods of obtaining informed consent and recording data. This report outlines 1 our experiences with securing recruitment to a qualitative study investigating alternative methods of data collection, and 2 the development of a standardised process for obtaining informed consent from individuals from minority ethnic backgrounds whose main language does not have an agreed written form. Methods Two researchers from South Asian backgrounds recruited adults with Type 2 diabetes whose main language was spoken and not written, to attend a series of focus groups. A screening tool was used at recruitment in order to assess literacy skills in potential participants. Informed consent was obtained using audio-recordings of the patient information and recording patients' verbal consent. Participants' perceptions of this method of obtaining consent were recorded. Results Recruitment rates were improved by using telephone compared to face-to-face methods. The screening tool was found to be acceptable by all potential participants. Audio-recorded methods of obtaining informed consent were easy to implement and accepted by all participants. Attrition rates differed according to ethnic group. Snowballing techniques only partly improved participation rates. Conclusion Audio-recorded methods of obtaining informed consent are an acceptable alternative to written consent in study populations where literacy skills are variable. Further exploration of issues relating to attrition is required, and a range of methods may be necessary in order to maximise response and participation rates.

    2016-12-01

    Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome (PMS) reported to affect 3-8 % of women of reproductive age and resulting in marked emotional and occupational impairment. Despite its prevalence, the etiology of PMDD is largely unknown, and patients remain mostly undiagnosed and poorly treated. It has been suggested that PMDD is a manifestation of underlying depressive disorder which is associated with the inability to regulate emotions in an adaptive manner. Therefore, we hypothesized that women with PMDD would exhibit increased difficulty with emotional regulation. A total of 648 female Israeli college students were assessed by the Premenstrual Symptoms Screening Tool (PSST) and the Difficulties in Emotion Regulation Scale (DERS). Of these women, 166 (25.6 %) met the criteria for PMS. Sixty-four (9.9 %) suffered from PMDD. More emotion regulation deficits were observed in the PMDD and PMS groups compared to the control group. Furthermore, there were more emotional regulation deficits among the predominantly psychological and mixed symptom subtype compared to the predominantly physical symptom subtype group. This is the first study to report an association between emotional dysregulation and PMDD. These findings may lead to development of more individually tailored treatment protocols focused on improving emotional regulation techniques.

    2012-08-01

    Density has been reported as one of the most difficult concepts for secondary school students (e.g. Smith et al. 1997). Discussion about the difficulties of learning this concept has been largely focused on the complexity of the concept itself or student misconceptions. Few, if any, have investigated how the concept of density was constituted in classroom interactions, and what consequences these interactions have for individual students' conceptual understanding. This paper reports a detailed analysis of two lessons on density in a 7th Grade Australian science classroom, employing the theory of Distributed Cognition (Hollan et al. 1999; Hutchins 1995). The analysis demonstrated that student understanding of density was shaped strongly by the public classroom discussion on the density of two metal blocks. It also revealed the ambiguities associated with the teacher demonstration and the student practical work. These ambiguities contributed to student difficulties with the concept of density identified in this classroom. The results of this study suggest that deliberate effort is needed to establish shared understanding not only about the purpose of the activities, but also about the meaning of scientific language and the utility of tools. It also suggests the importance of appropriate employment of instructional resources in order to facilitate student scientific understanding.

    The notion of an optimal difficulty during practice has been articulated in many areas of cognitive psychology: flow theory, the challenge point framework, and desirable difficulties. Delivering exercises at a participant's desired difficulty has the potential to improve both motor learning and users' engagement in therapy. Motivation and engagement are among the contributing factors to the success of exercise programs. The authors previously demonstrated that error amplification can be used to introduce levels of challenge into a robotic reaching task, and that machine-learning algorithms can dynamically adjust difficulty to the desired level with 85% accuracy. Building on these findings, we present the results of a proof-of-concept study investigating the impacts of practicing under desirable difficulty conditions. A control condition with a predefined random order for difficulty levels was deemed more suitable for this study (compared to constant or continuously increasing difficulty). By practicing the task at their desirable difficulties, participants in the experimental group perceived their performance at a significantly higher level and reported lower required effort to complete the task, in comparison to a control group. Moreover, based on self-reports, participants in the experimental group were willing, on average, to continue the training session for 4.6 more training blocks (∼45 min) compared to the control group's average. This study demonstrates the efficiency of delivering the exercises at the user's desired difficulty level to improve the user's engagement in exercise tasks. Future work will focus on clinical feasibility of this approach in increasing stroke survivors' engagement in their therapy programs.

    During the past two years, Investigación Clínica has undergone a substantial reduction in its funding caused by the insufficient budget allotment that the University of Zulia has received from the Venezuelan Government. The progressive increase in the number of articles contained in each issue of the journal caused its weight to exceed the established limits, affecting the distribution costs. Therefore, some adjustments to its structure and distribution are required to maintain its frequency and quality, including reducing the number of papers per issue and sacrificing free shipping to many libraries and health centers in our country and abroad. The "Instructions to Authors" will appear only in the first issue and we will keep the "Index of Authors" in the last issue of the year. Also the publishing of reprints will be limited and only will be sent to authors upon request and shipment pre-payment. Likewise, color pages fees will be canceled to the Publishers, prior to printing. For the above mentioned difficulties, we recommend our regular readers to use the website https://sites.google.com/site/revistainvestigacionesclinicas/, where all articles can be found in PDF format, as they appear in our printed edition. Despite these difficulties, all our collaborators will keep working to maintain the high standards that have characterized this journal for over 50 years, inspired by our founder, Dr. Américo Negrette.

    Full Text Available Many companies experience difficulty in implementing Just-in-Time (JIT in their manufacturing system. Based on observations, the article argues that the problem is partly due to confusion about JIT and its implications and partly due to a desire to implement JIT within an existing organisational structure. A four-level classification system is presented as a way of summarising the different degrees of JIT implementation and their difficulties.JIT philosophy has been of great interest to the manufacturers and researchers over the past few decades. JIT systems are designed to produce the goods & deliver services as and when required.JIT systems are capable to attain the far-reaching productivity and quality standards. Numerous benefits have been claimed by the firms implementing JIT across the World. Efforts are being made day-by-day to look into the benefits and their feasibility in the Manufacturing Industries. Despite the profound interest in it, the extent of implementation in India has not been satisfactory. Many firms which had benefitted from JIT systems appear to address only a few features, rather than looking into the whole philosophy of JIT. The paper attempts to address the necessary initiatives required to be taken by the Management of Indian Manufacturing Industry for the implementation of the various JIT subsets, through a survey based on previous literature. Further, it analyzes and concludes the modification of procedures and operations required for its successful implementation along with the challenges encountered during the JIT philosophy implementation.

    Translators always face dilemmas while translating source text into target text. Whether the language form is more im-portant than the real underlying meaning is constantly a controversial issue in translation. In practice, to keep the target text in the same genre and form as the source text and accurately render the original meaning from the author is highly difficult, espe-cially in literature translation. Therefore, previous research regarding difficulties in translating various languages in diverse cul-tures are to be reviewed, followed by a more specific context in which literature translations from Chinese to English and Eng-lish to Chinese are analyzed. Difficulties exposed in these translations are dealt with by experienced translators who employ vari-ous strategies. How effective these translations are in transmitting the original source language in both form and other functions are then evaluated. Moreover, the impacts that culture have on translation are further discussed. It comes to conclude that transla-tors may apply effective methods to minimize the gap between source language and target language, despite being unable to ex-actly render the meaning and form of the source text, especially when over one source language is involved.

    To develop an intervention procedure for spelling difficulties and to verify the effectiveness of the intervention program in students with lower spelling performance. We developed an intervention program for spelling difficulties, according to the semiology of the errors. The program consisted of three modules totaling 16 sessions. The study included 40 students of the third to fifth grade of public elementary education of the city of Marilia (SP), of both genders, in aged of eight to 12 years old, being distributed in the following groups: GI (20 students with lower spelling performance) and GII (20 students with higher spelling performance). In situation of pre and post-testing, all groups were submitted to the Pro-Orthography. The results statistically analyzed showed that, in general, all groups had average of right that has higher in post-testing, reducing the types of errors second semiologycal classification, mainly related to natural spelling errors. However, the results also showed that the groups submitted to the intervention program showed better performance on spelling tests in relation to not submitted. The intervention program developed was effective once the groups submitted showed better performance on spelling tests in relation to not submitted. Therefore, the intervention program can help professionals in the Health and Education to minimize the problems related to spelling, giving students an intervention that is effective for the development of the spelling knowledge.

    The present investigation examined the role of emotion regulation difficulties in predicting severity of the 3 posttraumatic stress disorder (PTSD) symptom clusters (i.e., reexperiencing, hyperarousal, avoidance) in a sample of undergraduates who reported exposure to at least 1 DSM-IV-TR Criterion A traumatic event (n = 297; 77.1% female, Mage = 20.46, SD = 4.64, range = 18-50 years). Results indicated that greater difficulties with emotional acceptance significantly predicted greater avoidance and hyperarousal symptom severity above and beyond the effects of number of trauma types endorsed and negative affect. Emotion regulation difficulties were not significantly predictive of reexperiencing symptom severity. Results from an exploratory analysis indicated that greater difficulties with emotional acceptance and greater difficulties accessing effective emotion regulation strategies when upset significantly predicted the DSM-5 negative alterations in cognitions and mood symptom cluster. These findings suggest that difficulties accepting one's emotional responses, in particular, may heighten emotional responding to and avoidance of trauma-related cues. Thus, individuals who experience such difficulties may be more likely to experience negative outcomes after experiencing a traumatic event.

    Deficits in speech perception are reported for some children with language impairments. This deficit is more marked when listening against background noise. This study investigated the speech perception skills of young children with and without language difficulties. A speech discrimination task, using non-word minimal pairs in an XAB paradigm, was presented to 20 5-7-year-old children with language difficulties and 33 typically-developing (TD) children aged between 4- to 7-years. Stimuli were presented in quiet and in background noise (babble), and stimuli varied in phonetic contrasts, differing in either place of articulation or presence/absence of voicing. Children with language difficulties performed less well than TD children in all conditions. There was an interaction between group and noise condition, such that children with language difficulties were more affected by the presence of noise. Both groups of children made more errors with one voicing contrast /s z/ and there was some indication that children with language difficulties had proportionately greater difficulty with this contrast. Speech discrimination scores were significantly correlated with language scores for children with language difficulties. Issues in developing material for assessment of speech discrimination in children with LI are discussed.

  7. Student difficulties regarding symbolic and graphical representations of vector fields

    Full Text Available The ability to switch between various representations is an invaluable problem-solving skill in physics. In addition, research has shown that using multiple representations can greatly enhance a person’s understanding of mathematical and physical concepts. This paper describes a study of student difficulties regarding interpreting, constructing, and switching between representations of vector fields, using both qualitative and quantitative methods. We first identified to what extent students are fluent with the use of field vector plots, field line diagrams, and symbolic expressions of vector fields by conducting individual student interviews and analyzing in-class student activities. Based on those findings, we designed the Vector Field Representations test, a free response assessment tool that has been given to 196 second- and third-year physics, mathematics, and engineering students from four different universities. From the obtained results we gained a comprehensive overview of typical errors that students make when switching between vector field representations. In addition, the study allowed us to determine the relative prevalence of the observed difficulties. Although the results varied greatly between institutions, a general trend revealed that many students struggle with vector addition, fail to recognize the field line density as an indication of the magnitude of the field, confuse characteristics of field lines and equipotential lines, and do not choose the appropriate coordinate system when writing out mathematical expressions of vector fields.

    2015-06-01

    Full Text Available Peripartum cardiomyopathy (PPCM is a disorder which describes initial left ventricular dysfunction and symptoms of cardiac failure between the late stages of pregnancy and the first five months after delivery. PPCM is a difficult diagnosis to make because it resembles common cardiac issues that are normally experienced during pregnancy. Clinical presentation is representative of cardiac failure and is commonly misdiagnosed until further progression. This disorder is commonly seen in some regions of the world and rare in others. Proper evaluation and rapid treatment are crucial for an effective recovery. Subsequent pregnancies should be evaluated before pursuing. The purpose of this review article is to discuss the difficulties in clinical diagnosis and provide a concise and practical approach to treatment of suspected PPCM.

  9. Exploring student difficulties with observation location

    Bryant, Jaime; Fischer, Susan M; Kustusch, Mary Bridget

    2015-01-01

    Throughout introductory physics, students create and interpret free body diagrams in which multiple forces act on an object, typically at a single location (the object's center of mass). The situation increases in difficulty when multiple objects are involved, and further when electric and magnetic fields are present. In the latter, sources of the fields are often identified as a set of electric charges or current-carrying wires, and students are asked to determine the electric or magnetic field at a separate location defined as the observation location. Previous research suggests students struggle with accounting for how a measurement or calculation depends on the observation location. We present preliminary results from a studio-style, algebra-based, introductory electricity and magnetism course exploring the extent to which students struggle with observation location by analyzing student written work involving vector addition of fields.

    2014-01-01

    Time perception has not been comprehensively examined in mathematics difficulties (MD). Therefore, verbal time estimation, production, and reproduction were tested in 13 individuals with MD and 16 healthy controls, matched for age, sex, and intellectual skills. Individuals with MD performed comparably to controls in time reproduction, but showed a tendency to be less accurate on tasks of verbal time estimation and time production. More specifically, these individuals overestimated the duration of a time interval in the verbal time estimation task and showed underproduction when required to produce a time sample. All previous significant comparisons remained significant after controlling for the effects of interval duration, working memory, attention allocation, and quantity estimation. These findings lead us to suggest that time estimation, and more specifically the "internal clock," is abnormally fast in individuals with MD. Results are discussed in terms of Meck and Church's model of temporal processing and Dehaene's triple code model for number processing.

    Full Text Available Understanding Maxwell’s equations in differential form is of great importance when studying the electrodynamic phenomena discussed in advanced electromagnetism courses. It is therefore necessary that students master the use of vector calculus in physical situations. In this light we investigated the difficulties second year students at KU Leuven encounter with the divergence and curl of a vector field in mathematical and physical contexts. We have found that they are quite skilled at doing calculations, but struggle with interpreting graphical representations of vector fields and applying vector calculus to physical situations. We have found strong indications that traditional instruction is not sufficient for our students to fully understand the meaning and power of Maxwell’s equations in electrodynamics.

    2007-01-01

    A group of seventh- and eighth-grade Italian students with low achievement (LA) in learning English as a foreign language (FL) was selected and compared to a group with high achievement (HA) in FL learning. The two groups were matched for age and nonverbal intelligence. Two experiments were conducted to examine the participants' verbal and nonverbal learning skills, such as native language reading accuracy, speed and comprehension, calculation, and attention and self-regulation. Both experiments showed that the LA group seemed at risk for reading comprehension difficulties, but its reading speed and accuracy were within the average range according to Italian norms. The results also excluded the possibility that FL learning difficulties of LA participants could be associated with a deficit in calculation. Furthermore, according to teachers' ratings, children with LA appeared at risk for attention-deficit disorder (ADD). The pattern of learning difficulties of seventh- and eighth-grade participants with LA appeared to be not completely comparable with that of high school students at risk of FL learning difficulties as described in the literature.

  20. Six-month-old infants' interaction difficulties are mirrored in their preference for perfect contingencies.

    Science.gov (United States)

    Zmyj, Norbert; Klein-Radukic, Sarah

    2015-01-01

    During the first months of life, infants switch from a preference for perfect contingent feedback to a preference for less-than-perfect contingent feedback of their own movements. This is an indicator of increasing social interest since others provide less-than-perfect contingent feedback whereas the self provides perfect contingent feedback. We presented 117 6-month-olds with real-time and delayed video feedback of self-performed leg movements and asked parents about difficulties in various socioemotional domains. It was hypothesized that the more infants prefer real-time and therefore perfect contingent feedback over 7 s delayed and therefore perceived noncontingent feedback, the more difficulties parents will report in interaction and communication with their child. Preference for real-time feedback was related to difficulties in interaction, but not to difficulties in communication. Implications of this finding for infants' socioemotional development and health are discussed.

    The first prenatal diagnosis of Pallister-Killian syndrome (PKS) was reported by Gilgenkrantz et al. in1985. Since this report, about 60 prenatal cases have been reported but both sonographic and cytogenetic diagnoses remain difficult. Although ultrasound anomalies such as congenital diaphragmatic hernia, polyhydramnios and rhizomelic micromelia in association with fetal overgrowth are very suggestive of the syndrome, they are inconstant and they may even be absent. The mosaic distribution of the supernumerary isochromosome 12p greatly increases these difficulties. No prenatal cytogenetic technique is sensitive enough to ensure prenatal diagnosis and false-negative results have been described on fetal blood, chorionic villi and amniocentesis. We report here two prenatal cases of PKS which illustrate the great variability of the fetal phenotype. In reviewing the 63 reported cases, we attempt to determine ultrasound indicators of the syndrome and to define a cytogenetic strategy. In cases where ultrasound indicators are present, our proposal is first to perform chorionic villus or placental sampling and then amniocentesis when the first cytogenetic result is normal. Fetal blood sampling is the least indicated method because of the low frequency of the isochromosome in lymphocytes. In this cytogenetic strategy, fluorescent in situ hybridization (FISH) and especially interphase FISH on non-cultured cells increases the probability or identifying the isochromosome. A misdiagnosis remains possible when ultrasound is not contributory; the identification of new discriminating ultrasound indicators would be very helpful in this context.

  9. Modelling the pelvic floor for investigating difficulties during childbirth

    Li, Xinshan; Kruger, Jennifer A.; Chung, Jae-Hoon; Nash, Martyn P.; Nielsen, Poul M. F.

    2008-03-01

    Research has suggested that athletes involved in high-intensity sports for sustained periods have a higher probability of experiencing prolonged second stage of labour compared to non-athletes. The mechanism responsible for this complication is unknown but may depend on the relative size or tone of the pelvic floor muscles. Prolonged training can result in enlargement and stiffening of these muscles, providing increased resistance as the fetal head descends through the birth canal during a vaginal birth. On the other hand, recent studies have suggested an association between increased muscle bulk in athletes and higher distensibility. This project aims to use mathematical modelling to study the relationship between the size and tone of the pelvic floor muscles and the level of difficulty during childbirth. We obtained sets of magnetic resonance (MR) images of the pelvic floor region for a female athlete and a female non-athlete. Thirteen components of the pelvic floor were segmented and used to generate finite element (FE) models. The fetal head data was obtained by laser scanning a skull replica and a FE model was fitted to these data. We used contact mechanics to simulate the motion of the fetal head moving through the pelvic floor, constructed from the non-athlete data. A maximum stretch ratio of 3.2 was induced in the muscle at the left lateral attachment point to the pubis. We plan to further improve our modelling framework to include active muscle contraction and fetal head rotations in order to address the hypotheses that there is a correlation between the level of difficulty and the size or tone of the pelvic floor muscles.

  10. Difficulties in Parenting Hearing-Impaired Children

    Dr. Gita Movallali

    2010-06-01

    Full Text Available Background and Aim: Despite the abundance of literature about deaf children, few works specifically address the concept and practice of difficulties in parenting hearing-impaired children. The first interactions of the child are with his parents, and parents have the most important role in child improvements during early intervention programs. The main purpose of this paper was to investigate different aspects of parenting hearing-impaired children.Methods: In this article, we reviewed all aspects of parenting hearing-impaired children in papers from 1984-2009 in Medline, Scopus and Proquest and relative textbooks. The semi-professional role of parents of hearing-impaired children make them feel under excessive stress and this usually affects their other roles as fathers and mothers. Many factors including child age, type of hearing loss and parents’ individual characteristics may influence the impact of child’s hearing loss on parents.Conclusion: Parenting a hearing-impaired child is both similar and different to parenting any other child. Where there are differences, there are usually challenges too. Taking support and advice from professionals and other parents are necessary and invaluable for parents of hearing-impaired children.

  11. A Case of Undiagnosed Sleep Disorder with Hearing Difficulty and Dizziness

    2016-03-01

    Full Text Available Introduction: The aim of this case report was to investigate the relationship between sleep disorders and audio vestibular symptoms.   Case Report: A case of undiagnosed sleep disorder, presenting as a temporary auditory processing difficulty, is presented. The disorder was initially treated as sudden deafness with dizziness. A 23-year-old male patient complained of acute hearing disturbance despite normal results on pure tone audiometry. The patient was initially administered a steroid injection in the hospital. After treatment, his hearing symptoms improved only slightly and he reported balance difficulty with rightward spontaneous nystagmus. Vestibular rehabilitation was performed. We also suspected that his hearing symptom was due to an auditory processing difficulty. Despite steroid treatment and vestibular rehabilitation, neither of his symptoms improved. We subsequently identified the presence of insomnia. He was prescribed zolpidem 5 mg, which slightly improved his symptoms, and referred to a sleep specialist for further examination. Polysomnography was performed, which identified restless leg syndrome and sleep disturbance with delayed sleep phase syndrome. After pharmacological treatment, his sleep disturbance, hearing difficulty, and balance disorder completely resolved.   Conclusion: Sleep disorders may provoke reversible auditory processing difficulties. We should carefully evaluate patients for a potentially undiagnosed sleep disorder, even in patients chiefly complaining of intractable sensory dysfunction such as hearing or balance disturbance.

    AIM To investigate whether perceptions of taskdifficulty on neuropsychological tests predicted academicachievement after controlling for glucose levels anddepression.METHODS: Participants were type 1 diabeticadolescents, with a mean age = 12.5 years (23 femalesand 16 males), seen at a northwest suburban Chicagohospital. The sample population was free of comorbidclinical health conditions. Subjects completeda three-part neuropsychological battery including theDigit Symbol Task, Trail Making Test, and ControlledOral Word Association test. Following each task,individuals rated task difficulty and then completeda depression inventory. Performance on these threetests is reflective of neuropsychological status inrelation to glucose control. Blood glucose levels weremeasured immediately prior to and after completingthe neuropsychological battery using a glucose meter.HbA1c levels were obtained from medical records.Academic performance was based on self-reportedgrades in Math, Science, and English. Data wasanalyzed using multiple regression models to evaluatethe associations between academic performance,perception of task difficulty, and glucose control.RESULTS: Perceptions of difficulty on a neuropsychologicalbattery significantly predicted academicperformance after accounting for glucose control anddepression. Perceptions of difficulty on the neuropsychologicaltests were inversely correlated withacademic performance (r = -0.48), while acute (bloodglucose) and long-term glucose levels increasedalong with perceptions of task difficulty (r = 0.47).Additionally, higher depression scores were associated Potts TM et al . Perception of difficulty, glucose, and academics with poorer academic performance (r = -0.43). With the first regression analysis, perception of difficulty on the neuropsychological tasks contributed to 8% of the variance in academic performance after controlling for peripheral blood glucose and depression.

    Current methods for determining the astrometry positions of digitized photographic plates have difficulty for correctly using data from different telescopes. Factors such as scale of a plate, exposure duration, size of the plate and its quality, affect the accuracy of the results. Scanner options add their mistakes. Often, it is important to get results in prolonged time period. In such cases, we use observational data that were obtained using different telescopes. Then there is the need to balance the various data accuracy. The report provides a methodical approach. The method has been tested for some standard star fields.

    2011-01-01

    Children with specific language impairment (SLI) have often been reported to have associated behavioral, emotional and social difficulties. Most previous studies involve observations at a single time point, or cross sectional designs, and longitudinal evidence of the developmental trajectories of particular difficulties is limited. The Strengths and Difficulties Questionnaire was used to measure behavioral (hyperactivity and conduct), emotional and social (peer) problems in a sample of individuals with a history of SLI at four time points from childhood (age 7) to adolescence (age 16). A decrease in behavioral and emotional problems was observed from childhood to adolescence, although emotional problems were still evident in adolescence. In contrast, there was an increase in social problems. Reading skills and expressive language were related only to behavioral problems. Pragmatic abilities were related to behavioral, emotional and social difficulties. As a group, those with a history of SLI have poorer long term social and, to a lesser extent, emotional outcomes. In contrast, behavioral difficulties appear to decrease to normative levels by adolescence. Different aspects of early language abilities and reading skills exert different types and degrees of influence on behavioral, emotional and social difficulties. Readers will be able to: (1) understand the types of behavioral, emotional and social difficulties present in individuals with a history of SLI; (2) be familiar with the developmental trajectory of these difficulties from childhood to adolescence; and (3) understand the relationships between behavioral, emotional and social difficulties and early language and literacy ability.

    Speech/language disorders are common in the fragile X syndrome. [Howard-Peebles, 1979: Am J Hom Genet 31:214-222; Renier et al., 1983: J Ment Defic Res 27:51-59; Sparks, 1984: Birth Defects and Speech-Language Disorders, pp. 39-43; Hanson et al., 1986: Am J Med Genet 23:195-206]. Verbal paraphasias have been considered a rare feature and word-finding difficulties have seldom been reported. Here we report on ten Brazilian patients who were evaluated for speech/language disturbances and found that word-finding difficulties were present in 50% of the cases, which is a slightly higher frequency than that of clear dyspraxia. We suggest, therefore, that word-finding difficulties and verbal dyspraxia can be a common feature within the spectrum of this syndrome. Additional speech findings are discussed.

    Multiple attempts at spinal puncture may be hazardous. Accurate preoperative prediction of difficulty adds to the delivery of high quality care. This clinical trial was designed to: (i). determine the predictive performance of difficulty variables; (ii). compare senior and junior anaesthetists; (iii). develop a score to predict difficulty during the performance of spinal anaesthesia. A total of 300 patients subjected to urological procedures and scheduled for spinal anaesthesia were independently assessed and stratified according to the categories of the difficulty predictors of spinal anaesthesia into one of nine grades (0-8) and randomized according to the experience of the anaesthetist into two groups (group A, staff with more than 15 yrs' experience; group B, resident with more than 6 months but less than 1 yr in training). The number of attempts and levels, and success rate of the technique were the outcome variables. Data were analysed by multivariate analysis and receiver operating characteristic (ROC) curves. The bony landmarks of the back and the radiological characteristics of the lumbar vertebrae were two independent predictors of difficulty. Multivariate analysis indicated differences between junior and senior staff but ROC curves indicated no difference. Grade 4 was the difficulty score at or above which difficulty was expected whether or not radiological characteristics of the vertebrae were included. Spinal bony landmarks and radiological characteristics of the lumbar vertebrae are independent predictors of difficulty during spinal anaesthesia. There is no difference between senior and junior anaesthetists. Grade 4 is the difficulty score at or above which difficulty is expected.

  5. Axonal recordings from medial superior olive neurons obtained from the lateral lemniscus of the chinchilla (Chinchilla laniger).

    2013-10-30

    Interaural time differences (ITDs) are a major cue for localizing low-frequency (sounds. Sensitivity to this cue first occurs in the medial superior olive (MSO), which is thought to perform a coincidence analysis on its monaural inputs. Extracellular single-neuron recordings in MSO are difficult to obtain because (1) MSO action potentials are small and (2) a large field potential locked to the stimulus waveform hampers spike isolation. Consequently, only a limited number of studies report MSO data, and even in these studies data are limited in the variety of stimuli used, in the number of neurons studied, and in spike isolation. More high-quality data are needed to better understand the mechanisms underlying neuronal ITD-sensitivity. We circumvented these difficulties by recording from the axons of MSO neurons in the lateral lemniscus (LL) of the chinchilla, a species with pronounced low-frequency sensitivity. Employing sharp glass electrodes we successfully recorded from neurons with ITD sensitivity: the location, response properties, latency, and spike shape were consistent with an MSO axonal origin. The main difficulty encountered was mechanical stability. We obtained responses to binaural beats and dichotic noise bursts to characterize the best delay versus characteristic frequency distribution, and compared the data to recordings we obtained in the inferior colliculus (IC). In contrast to most reports in other rodents, many best delays were close to zero ITD, both in MSO and IC, with a majority of the neurons recorded in the LL firing maximally within the presumed ethological ITD range.

    Aim. This study aims to explain the main steps that characterize the implant-prosthetic rehabilitation in complex combined dental and maxillofacial trauma. Material and Methods. A 20-year-old patient reported an extensive facial trauma which also involved the alveolar process of the maxillary bone. The patient reported a maxillofacial fracture and the loss of teeth 1.3, 1.2, 1.1, and 2.1. A “Le Fort” type 2 fracture was also reported, with the malar bone involvement. After reduction and containment of bone fractures, through appropriate mounting plates, appropriate functional and aesthetic rehabilitation of the patient were replaced thanks to a temporary removable prosthesis. After 6 months, the patient performed numerous clinical investigations, aimed at a proper planning of implant-prosthetic rehabilitation of the upper dental arch. Conclusion. With the planning of the case, as well as respecting the surrounding biological structures, the surgery of implants can be carried out with the most appropriate procedure. Lastly, new dental implants with highly bioactive surfaces have been developed, providing an excellent and rapid bone integration. PMID:28392948

    The financial difficulty of dementia caregivers and its effects on mental health has gained increasing attention from researchers. The present study examines the longitudinal relationship between financial difficulty and the depressive symptoms of dementia caregivers using matching methods to account for potential selection bias. Propensity score matching methods and mixed-effects models were used to determine the effects of financial difficulty on depressive symptoms among caregivers participating in the Resources for Enhancing Alzheimer's Caregiver Health (REACH) intervention program. Propensity score matching confirmed that caregivers experiencing financial difficulty were more likely to have depressive symptoms. The results suggest that dementia caregivers require support for their financial difficulty. Future research should fully examine the complex relationship between financial difficulty and the mental health of caregivers and how this issue can be addressed through assessment and intervention methods.

    Alloimmunization against high-frequency erythrocyte antigens is a problematic situation in terms of laboratory diagnosis, transfusion and obstetrical management. We report the case of a pregnant woman alloimmunized against public Ag. We detail the difficulties of alloantibody (Ab) identification and transfusion management of the deliveries. A 29-year-old pregnant woman was hospitalized in gynecology and obstetrics departments at 36 weeks of gestation for assessment of hydrops fetalis. Antibody identification test revealed the presence of a pan-reactive antibody. Investigations realized in CNRGS (Paris) concluded in anti-GE2+anti-RH3+autoantibody. The red cell phenotype was GE: -2,3. A therapeutic interruption of the pregnancy was indicated. A program of autologous transfusion was organized with withdrawal of 2 units of blood. The 2nd pregnancy took place normally. Before delivery, an autologous blood reserve consisting of 2 red cell packs and 2 fresh frozen plasma was withdrawn and transfused after delivery. The management of anti-public alloimmunization poses several problems. The first one is of diagnostic nature with, on the one hand, the difficulty of Ab identification by the available red cell panels and, on the other hand, the possible presence of alloantibodies of transfusional or obstetric interest masked by anti-public Ab. The second is represented by transfusional care of these patients. In the absence of a national reserve of frozen rare blood, the autologous transfusion remains the only alternative. However, it can answer only a limited number of indications and only in case of moderate blood loss.

    People with developmental disorders frequently have psychiatric comorbidities and problematic emotional reactions and behaviors. We commonly calls these conditions "nizi-shougai (secondary difficulties)" in Japan. But there is no clear definition of "nizi-shougai", and it is impossible to distinguish "secondary difficulties" from the problems derived from Asperger syndrome itself. In this paper, I focus on psychiatric comorbidities and emotional difficulties of Asperger syndrome. Early detection and intervention for children with developmental disorders can prevent some kind of "secondary difficulties". Treatment for Asperger syndrome should be tailored to meet individual characteristics and needs.

    Background: The quality of academic training can best be analyzed by including the student’s perceptions. The aim of this study is to evaluate the short comings in preclinical endodontic training and also to find out key areas to stress upon for better student understanding and treatment outcome. Materials and Methods: A total of 72 structured questionnaires were distributed to the dental students who have already entered or finished clinical endodontic training in 4th year after successfully completing the preclinical endodontic course in 3rd year. The questions were focused on the list of difficulties encountered during each step of endodontics including patient consideration, access related difficulties, difficulties during working length determination, cleaning and shaping and obturation. The difficulty level for each of the questions was also rated on a scale of 1-3. About 88% of the questionnaires were returned for evaluation. The obtained answers were analyzed generating a data showing the type and level of difficulty. Results: Locating the apical constriction and controlling the length of the master cone has the highest percentage of difficulty among all the groups. Conclusions: This study helped in highlighting key areas of difficulties faced by the students. The training for students in future needs to be amended so that they are better able to manage such difficulties. PMID:26225100

    Quantum states of the electromagnetic field are of considerable importance, finding potential application in various areas of physics, as diverse as solid state physics, quantum communication and cosmology. In this paper we introduce the concept of truncated states obtained via iterative processes (TSI) and study its statistical features, making an analogy with dynamical systems theory (DST). As a specific example, we have studied TSI for the doubling and the logistic functions, which are standard functions in studying chaos. TSI for both the doubling and logistic functions exhibit certain similar patterns when their statistical features are compared from the point of view of DST. A general method to engineer TSI in the running-wave domain is employed, which includes the errors due to the nonidealities of detectors and photocounts.

  11. Perceptual discrimination difficulty and familiarity in the Uncanny Valley: More like a ‘Happy Valley’.

    Full Text Available The Uncanny Valley Hypothesis (UVH predicts that enhanced difficulty perceptually discriminating between categorically ambiguous human and humanlike characters (e.g., highly realistic robot evokes negatively valenced (i.e., uncanny experience. An ABX perceptual discrimination task and signal detection analysis was used to examine perceptual discrimination (PD difficulty along the UVH' dimension of human likeness (DHL represented using avatar-to-human morph continua. Rejecting the implicit assumption underlying the UVH' prediction, Experiment 1 confirmed that PD difficulty was lowest for categorically ambiguous (and avatar faces and, notably, greatest for human faces. Rejecting the UVH’ predicted positive relationship between greater PD difficulty and negative affective experience (i.e. assessed in terms of the UVH' familiarity dimension, Experiment 2 demonstrated that greater PD difficulty correlates with more positively rather than negatively valenced affective experience. Critically, this effect was strongest for ambiguous faces, suggesting a relationship between PD difficulty and familiarity more consistent with the metaphor happy valley. These findings are also consistent with a fluency amplification instead of the hitherto proposed hedonic fluency account of experienced affect along the DHL. Experiment 3 found no evidence to suggest that the reported asymmetry in the profile of PD along the DHL is attributable to a differential processing strategy (as in the other-race effect, i.e., processing avatars at a category and human faces at an individual level. In conclusion, these findings for static faces strongly challenge the UVH’ prediction, demonstrating no support for the UVH' assumed distribution of PD difficulty along the DHL and the predicted relationship between this and familiarity.

    Full Text Available This paper is based on a study by Joffe and Pring (2008 which investigated assessment and therapy methods used by Speech Language Therapists (SLTs in the United Kingdom for children with phonological difficulties. Joffe and Pring reported SLTs’ most favoured assessments and therapy approaches in that context. Children with speech difficulties are likely to form a considerable part of SLT caseloads in South Africa, but the choice of assessments may not be so clearcut given the linguistic diversity of the region and the fact that few assessments have been developed specifically for the SA population. Linked to difficulties with assessment, selection of intervention approaches may also pose challenges. This study aimed to investigate the methods of assessment and intervention used by SLTs in the Western Cape when working with children with speech difficulties. A questionnaire was sent to SLTs working with pre and/ or primary school- aged children. Twenty-nine clinicians of varying experience responded. The majority of SLTs (89% use informal assessment tools in combination with formal assessment. When using formal assessments, more than 50% of SLTs make modifications to better suit the population. Participants use a variety of intervention approaches, often in combination, and based on a child’s individual profile of difficulties and available resources. Forty-six percent of SLTs felt unsure about the selection of assessments and intervention for bi/multilingual children with speech difficulties. SLTs suggested that guidelines about accepted / typical speech development in the region would be helpful for their clinical practice. Clinical implications of the findings are discussed together with some suggestions for developing knowledge of children’s speech difficulties in the South African context.

  18. Obtaining Reliable Feedback for Sanctioning Reputation Mechanisms

    CERN Document Server

    Faltings, B; 10.1613/jair.2243

    2011-01-01

    Reputation mechanisms offer an effective alternative to verification authorities for building trust in electronic markets with moral hazard. Future clients guide their business decisions by considering the feedback from past transactions; if truthfully exposed, cheating behavior is sanctioned and thus becomes irrational. It therefore becomes important to ensure that rational clients have the right incentives to report honestly. As an alternative to side-payment schemes that explicitly reward truthful reports, we show that honesty can emerge as a rational behavior when clients have a repeated presence in the market. To this end we describe a mechanism that supports an equilibrium where truthful feedback is obtained. Then we characterize the set of pareto-optimal equilibria of the mechanism, and derive an upper bound on the percentage of false reports that can be recorded by the mechanism. An important role in the existence of this bound is played by the fact that rational clients can establish a reputation for...

  19. Identifying Student Difficulties with Entropy, Heat Engines, and the Carnot Cycle

    CERN Document Server

    Smith, Trevor I; Mountcastle, Donald B; Thompson, John R

    2015-01-01

    We report on several specific student difficulties regarding the Second Law of Thermodynamics in the context of heat engines within upper-division undergraduates thermal physics courses. Data come from ungraded written surveys, graded homework assignments, and videotaped classroom observations of tutorial activities. Written data show that students in these courses do not clearly articulate the connection between the Carnot cycle and the Second Law after lecture instruction. This result is consistent both within and across student populations. Observation data provide evidence for myriad difficulties related to entropy and heat engines, including students' struggles in reasoning about situations that are physically impossible and failures to differentiate between differential and net changes of state properties of a system. Results herein may be seen as the application of previously documented difficulties in the context of heat engines, but others are novel and emphasize the subtle and complex nature of cycl...

  7. CHINESE EFL UNDERGRADUATES’ ACADEMIC WRITING: RHETORICAL DIFFICULTIES AND SUGGESTIONS

    Directory of Open Access Journals (Sweden)

    Xiaoyun Bian

    2016-07-01

    Full Text Available Difficulties encountered by students in L2 academic writing has been a subject of research for several decades. However, to date, there still remains a lack of detailed and in-depth investigation into this area of interest. This qualitative study thoroughly investigated the rhetorical difficulties faced by Chinese EFL undergraduate academic writers, and collected suggestions on how to address these rhetorical issues. To be sufficiently detailed and thorough, this study divided students' difficulties into process- and product-related difficulties, and used triangulated data from supervisors' perspectives, students' perspectives, and supervisors' comments to address research questions. Although there were no strong generalizations derived from data from different perspectives and sources, the findings of this study showed supervisor perceptions of the rhetorical difficulties the students experienced were almost identical. In nature these rhetorical difficulties were culturallyembedded and genre-related issues; and the degree of difficulty experienced by each student varied. In this study, supervisors and students both suggested that, to solve rhetorical difficulties, teacher student communication should be improved. This study provided empirical evidence to contrastive rhetoric theory and socio-cultural theory. It also offered suggestions on how to strengthen future research in this area of inquiry, and how to improve academic writing teaching in L2 educational contexts.

  14. The role of sensorimotor difficulties in autism spectrum conditions

    Directory of Open Access Journals (Sweden)

    Penelope Hannant

    2016-08-01

    Full Text Available AbstractIn addition to difficulties in social communication, current diagnostic criteria for autism spectrum conditions (ASC also incorporate sensorimotor difficulties; repetitive motor movements and atypical reactivity to sensory input (APA, 2013. This paper explores whether sensorimotor difficulties are associated with the development and maintenance of symptoms in ASC. Firstly, studies have shown difficulties coordinating sensory input into planning and executing movement effectively in ASC. Secondly, studies have shown associations between sensory reactivity and motor coordination with core ASC symptoms, suggesting these areas each strongly influence the development of social and communication skills. Thirdly, studies have begun to demonstrate that sensorimotor difficulties in ASC could account for reduced social attention early in development, with a cascading effect on later social, communicative and emotional development. These results suggest that sensorimotor difficulties not only contribute to non-social difficulties such as narrow circumscribed interests, but also to the development of social behaviours such as effectively coordinating eye contact with speech and gesture, interpreting others’ behaviour and responding appropriately. Further research is needed to explore the link between sensory and motor difficulties in ASC, and their contribution to the development and maintenance of ASC.

    2015-01-01

    At least 60% of young people in the UK who are accessing youth justice services present with speech, language and communication difficulties which are largely unrecognized. The contributing reasons for this are discussed, suggesting that early language difficulty is a risk factor for other problems such as literacy difficulties and educational failure that may increasingly put the young person at risk of offending. Opportunities for identification and remediation of language difficulties before young people reach youth justice services are also outlined. To examine language skills in a sample of children in a secure children's home aged 11-17 years. A sample of 118 males were routinely assessed on four Comprehensive Evaluation of Language Fundamentals (CELF) subtests and the British Picture Vocabulary Scale (BPVS). Around 30% of the participants presented with language difficulties scoring 1.5 SD (standard deviation) below the mean on the assessments. Despite them entering the home because their vulnerability was recognized, only two participants had a previous record of language difficulties. A total of 20% of the participants had a diagnosis of mental illness, 50% had a history of drug abuse and 31% had looked-after status prior to entry to the home. Children experiencing educational or emotional difficulties need to be routinely assessed for speech, language and communication difficulties. More population-based approaches to supporting the development of oral language skills in children and young people are also supported. © 2015 Royal College of Speech and Language Therapists.

    Paul Leslie Gardner pioneered the study of student difficulties with everyday words presented in the science context (Gardner 1971); several similarly designed studies (e.g. Cassels and Johnstone 1985; Tao in Research in Science Education, 24, 322-330, 1994; Farell and Ventura in Language and Education, 12(4), 243-254, 1998; Childs and O'Farell in Chemistry Education: Research and Practice, 4(3), 233-247, 2003) have since been reported in literature. This article draws from an exploratory study of the difficulties South African High School physical science learners encounter with everyday English words when presented in the science context. The participants (1107 learners and 35 respective physical science teachers) were drawn from 35 public secondary schools in Johannesburg area of South Africa. Data were obtained through a word test to participant learners followed by group interviews but face-to-face interviews with each physical science teacher. This study has revealed that in similar ways as have been reported in each of the studies so far, South African learners also face difficulties with meanings of everyday words presented in a science context. The main source of difficulties encountered was learner inability to distinguish between the meanings of familiar everyday words as used in everyday parlance from the `new' meanings of the same everyday words when used in the science context. Interpretations of learner interview responses revealed that fewer difficulties would have been experienced by learners if science teachers generally explained the context meanings of the words as used during science teaching. The findings suggest that focusing on contextual proficiency more than on general proficiency in the language of learning and teaching (LOLT) during teaching perhaps holds more promise for enhanced learning and achievement in science.

    Full Text Available Background and objective: Prediction of intubation difficulty can save patients from major preoperative morbidity or mortality. The purpose of this paper is to assess the correlation between oro-hypo pharynx position, neck size, and length with endotracheal intubation difficulty. The study also explored the diagnostic value of Friedman Staging System in prediction cases with difficult intubation. Method: The consecutive 500 ASA (I, II adult patients undergoing elective surgery were evaluated for oro and hypopharynx shape and position by modified Mallampati, Cormack and Lehane score as well as Friedman obstructive sleep apnea classification systems. Neck circumference and length were also measured. All cases were intubated by a single anesthesiologist who was uninformed of the above evaluation and graded intubation difficulty in visual analog score. Correlation between these findings and difficulty of intubation was assessed. Sensitivity, Specificity, Positive and Negative Predictive Values were also reported. Results: Cormack-Lehane grade had the strongest correlation with difficulty of intubation followed by Friedman palate position. Friedman palate position was the most sensitive and had higher positive and negative predictive values than modified Mallampati classification. Cormack-Lehane grade was found to be the most specific with the highest negative predictive value among the four studied classifications. Conclusion: Friedman palate position is a more useful, valuable and sensitive test compared to the modified Mallampati screening test for pre-anesthetic prediction of difficult intubation where its involvement in Multivariate model may raise the accuracy and diagnostic value of preoperative assessment of difficult airway.

    2014-12-01

    Geophysics is a wonderfully diverse field of study, encompassing a variety of disciplines greatly different from one other. Even within the same discipline, various branches of study can have drastically different vocabulary and methodologies. The difficulty of breaking this "jargon" barrier is also an important reminder for scientists of how critical it is to clearly and concisely convey information. This presentation will focus on strategies that students can focus on to ease a transition between fields in geophysics. I believe that a student changing disciplines should proceed in the following steps: [1] Do a cursory literature review to find a review paper of the desired topic and work backwards through the details until a level of understanding or recognition is reached, [2] Obtain a clear physical understanding of the data and methods of the proposed study, and [3] Establish a support network through the research group or elsewhere which will recognize the areas in which the student is behind and offer remedies in a supportive and productive manner. These strategies are based on my own personal experience changing from music to geophysics in my undergrad and working on projects spanning various subdisciplines of geophysics during my Masters and PhD. It is worthwhile for research groups to spend the time to mentor students switching from other disciplines because those students will in time be able to observe the research in a different way than their peers, and easily adapt to changes of direction within the research.

    Motor deficits are linked to a range of negative physical, social and academic consequences. Haptic robotic interventions, based on the principles of sensorimotor learning, have been shown previously to help children with motor problems learn new movements. We therefore examined whether the training benefits of a robotic system would generalise to a standardised test of 'pen-skills', assessed using objective kinematic measures [via the Clinical Kinematic Assessment Tool, CKAT]. A counterbalanced, cross-over design was used in a group of 51 children (37 male, aged 5-11 years) with manual control difficulties. Improved performance on a novel task using the robotic device could be attributed to the intervention but there was no evidence of generalisation to any of the CKAT tasks. The robotic system appears to have the potential to support motor learning, with the technology affording numerous advantages. However, the training regime may need to target particular manual skills (e.g. letter formation) in order to obtain clinically significant improvements in specific skills such as handwriting.

    Full Text Available The role of alcohol on fertility remains unclear. We aimed to investigate the association between alcohol and specific alcoholic beverages consumption and the risk of difficulty getting pregnant. We used a case-control study nested within the Seguimiento Universidad de Navarra (SUN cohort, a prospective, dynamic and multipurpose cohort of 21,705 Spanish university graduates, followed biennially with mailed questionnaires. We identified 686 case-control pairs, matched for age and time in the cohort. Cases were women reporting difficulty getting pregnant. Controls did not consult due to difficulty conceiving and had at least one child during follow-up. After adjustment for potential confounders, we found no association between self-reported difficulty getting pregnant and the number of alcoholic beverages consumed per week, (Odds Ratio [OR] > 5 drinks/week vs. none = 1.04, 95% Confidence Interval [CI] = 0.72–1.51. No association between types of alcoholic beverage and difficulty conceiving (OR > 5 drinks of wine/week vs. none = 1.16, 95% CI = 0.72–1.88; OR > 5 drinks of beer/week vs. none = 1.06, 95% CI = 0.82–1.37; OR > 5 drinks of spirits/week vs. none = 1.24, 95% CI = 0.84–1.64 was observed. In conclusion, we found no association between alcohol intake and risk of consulting a physician due to difficulty conceiving. More studies are needed to clearly elucidate the effects of alcohol intake on women’s fertility. In the meantime, recommendations about alcohol intake to couples trying to conceive have to be given cautiously.

    To assess the influence of subjective word-finding difficulty on degree of engagement in social leisure activities among individuals with Alzheimer's disease (AD). Analysis of data collected from the second cohort of the Multicenter Study of Predictors of Disease Course in Alzheimer's disease. Four study sites in the United States and France. Individuals diagnosed with mild to moderate AD (N = 236). On separate questionnaires, participants were asked to 1) report whether they had trouble finding the right word when speaking (subjective word-finding difficulty) and 2) rate their frequency and enjoyment of social and nonsocial leisure activities. Objective language measures included object naming and verbal fluency. Measures of dependence, depression, cognitive status, age, sex, and education were also included as covariates in regression analyses. Fifty-two percent of the sample reported word-finding difficulty, and subjective complaints were correlated with poorer verbal fluency scores. Subjective word-finding difficulty was selectively related to social but not nonsocial activity measures. Endorsers of word-finding difficulty reported less frequency and enjoyment of social leisure activities, controlling for effects of covariates and objective word-finding ability. In contrast, lower engagement in nonsocial activities was associated with older age and higher depression scores but not with word-finding complaints. Caregivers' reports of study participants' activities corroborated these results. Individuals with AD who are aware of increasing word-finding failures are less likely to participate in and enjoy socially oriented leisure activities. This finding may have significant implications for clinical and health outcomes in AD. Failure to evaluate subjective language complaints could result in social withdrawal symptoms, threatening the individual's quality of life and increasing caregiver burden. Reduced social interaction may ultimately exacerbate language

    Full Text Available Compliance with gluten-free diet is the basic method for controlling coeliac disease in patients regardless of their age. It may be, however, challenging to follow in daily life. The prevalence of the disease (approx. 1% of European population is affected makes it an important public health problem. Aim of the study: Investigating the difficulties and obstacles related to compliance with gluten-free diet by children and adult patients living in Upper Silesia region. Material and method: The study included 30 mothers of children with coeliac disease (Group I and 30 adult coeliac disease patients (Group II. The patients kept a gluten-free diet. Data were obtained in an anonymous survey drawn up for the purpose of this study, conducted in 2010. Results: The respondents reported a very limited access to gluten-free meals in mass-catering establishments (76.7% of the participants in Group II, and 70% children at nurseries, kindergartens and schools, lack of adequate food product labelling (93% in both groups, difficulties experienced in social life (60% in Group II, difficulties experienced when travelling within Poland (76.7% in Group II and abroad (83.3% in Group II, and no existing reimbursement plan for the high diet costs (16.7% in Group I vs. 26.7% in Group II. Conclusions: 1 The necessity of compliance with gluten-free diet causes a lot of difficulties in everyday life to patients with coeliac disease and parents of children suffering from coeliac disease. Proper treatment requires their identification by the attending physician. 2 Improved food labelling as regards gluten content as well as inclusion of gluten-free meals in the menu of food-serving establishments will contribute to improved quality of life of children and adults suffering from coeliac disease. 3 Associations of patients on a gluten-free diet should continue their efforts to have high costs of this diet refunded.

    The purpose of the study was to investigate speed of processing in college students with a history of problems with language. Affected individuals (n=16) were identified through a self-reported history of language and/or reading difficulties, and compared to a group of 16 unaffected individuals. Measures of language ability and a battery of response time tasks were administered. Results showed that the affected group had lower language performance and slower response time than the unaffected group. Better language performance was associated with faster response time, and this relationship was stronger in the affected group. These findings are consistent with the literature showing that language impairment often persists into adulthood. Further investigation of the relation between processing speed and language ability may help describe vulnerabilities for adults with language problems, as well as ways to promote compensation for those vulnerabilities. Readers will (1) increase understanding of associations between processing speed and language in children and adults; (2) become familiar with a method for assessing processing speed; and (3) increase understanding of possible vulnerabilities in adults with a history of language and/or reading problems.

    The current study investigated the longitudinal, reciprocal associations between stressful events and psychological difficulties from early childhood to mid-adolescence. Child age, sex, prenatal maternal anxiety, and difficult temperament were tested as sources of sensitivity, that is, factors that may make children more sensitive to stressful life events. Analyses were based on data from 10,417 children from a prospective, longitudinal study of child development. At ages 4, 7, 9, 11, and 16 years, stressful events and psychological difficulties were measured. Prenatal anxiety was measured at 32 weeks of gestation and difficult temperament was measured at 6 months. Children exposed to stressful events showed significantly increased psychological difficulties at ages 7 and 11 years; there was consistent evidence of a reciprocal pattern: psychological difficulties predicted stressful events at each stage. Analyses also indicated that the associations between stressful events and psychological difficulties were stronger in girls than in boys. We found no evidence for the hypothesis that prenatal anxiety or difficult temperament increased stress sensitivity, that is, moderated the link between life events and psychological difficulties. The findings extend prior work on stress exposure and psychological difficulties and highlight the need for additional research to investigate sources of sensitivity and the mechanisms that might underlie differences in sensitivity to stressful events.

  4. The Prevalence of Reading Difficulties among Children in Scholar Age

    Full Text Available The study investigates the prevalence of reading difficulties among children in scholar age and analyses the socio-demographic characteristics of learners who presented reading difficulties in central Italy. A sample of 623 students 7-11 aged, was assessed with the Italian MT standardized tests. Information on gender, age, handedness, and other socio-demographic variables were also gathered. The study showed that 11% of learners presented poor comprehension skills. The reading speed difficulties were more common than the reading correctness problems: about 7% of children vs 1% were dyslexics due to slow reading. There were no significant differences regarding gender, age. However, dominant hand and the school location seemed to affect the speed difficulties and the comprehension problems. The analyses showed that attending a school located in a rural area was statistically associated with the reading difficulties. Left-handed children were more likely to be slow decoders and/or poor comprehenders. These findings may be used in the early diagnosis of poor readers. These difficulties often have a chronic progression with substantial psychosocial limitations and psychological stress, so children with reading difficulties should be identified as early as possible.

  5. No One Knows: Offenders with learning disabilities and learning difficulties.

    2009-01-01

    No One Knows is concerned about people with learning disabilities and difficulties who get into trouble with the police and who enter the criminal justice system. The terms 'learning difficulties' and 'learning difficulties' are often used interchangeably to describe people with an intellectual disability, excluding those who, for example, have dyslexia or Asperger syndrome. No One Knows, however, has adopted a more inclusive approach and has included in its remit offenders with learning disabilities as defined by the World Health Organization as well as those with a broader range of learning difficulties. Although there is some discrepancy on prevalence, it is clear that high numbers of people with learning disabilities and difficulties are caught up in the criminal justice system. Once in the criminal justice system it is unlikely that an individual with learning disabilities or difficulties will be identified or that their support needs will be met. This causes difficulties for the individual concerned and for the staff who work with them, who receive little or no training for working with this group of people. The question of whether people with learning disabilities (meaning intellectual disabilities) should be diverted from the criminal justice system is considered.

    This study aimed to determine whether age at introduction of solid foods was associated with feeding difficulties at 3 years of age. The present study was carried out using data from the Southampton Women's Survey (SWS). Women enrolled in the SWS who subsequently became pregnant were followed-up during pregnancy and postpartum, and the offspring have been studied through childhood. Maternal socio-demographic and anthropometric data and child anthropometric and feeding data were collected through interviews and self-administered questionnaires. When the children were 3 years of age, mothers/carers rated six potential child feeding difficulty questions on a four-point Likert scale, including one general question and five specific feeding difficulty questions. Age at introduction of solids as a predictor of feeding difficulties was examined in 2389 mother-child pairs, adjusting for child (age last breast fed, sex, gestation) and maternal characteristics (parity, pre-pregnancy BMI, age, education, employment, parenting difficulties, diet quality). The majority of mothers/carers (61 %) reported some feeding difficulties (general feeding difficulty question) at 3 years of age, specifically with their child eating enough food (61 %), eating the right food (66 %) and being choosy with food (74 %). Children who were introduced to solids ≥6 months had a lower risk of feeding difficulties (RR 0·73; 95 % CI 0·59, 0·91, P=0·004) than children who were introduced to solids between 4 and 6 months. No other significant associations were found. There were few associations between feeding difficulties in relation to age at introduction of solid foods. However, general feeding difficulties were less common among infants introduced to solid foods ≥6 months of age.

    This study aimed to quantify the non-hospital healthcare costs associated with language difficulties within two nationally representative samples of children. Data were from three biennial waves (2004-2008) of the Longitudinal Study of Australian Children (B cohort: 0-5 years; K cohort: 4-9 years). Language difficulties were defined as scores ≤ 1.25 SD below the mean on measures of parent-reported communication (0-3 years) and directly assessed vocabulary (4-9 years). Participant data were linked to administrative data on non-hospital healthcare attendances and prescription medications from the universal Australian Medicare subsidized healthcare scheme. It was found that healthcare costs over each 2-year age band were higher for children with than without language difficulties at 0-1, 2-3, and 4-5 years, notably 36% higher (mean difference = $AU206, 95% CI = $90, $321) at 4-5 years (B cohort). The slightly higher 2-year healthcare costs for children with language difficulties at 6-7 and 8-9 years were not statistically different from those without language difficulties. Modelled to the corresponding Australian child population, 2-year government costs ranged from $AU1.2-$AU12.1 million (depending on age examined). Six-year healthcare costs increased with the persistence of language difficulties in the K cohort, with total Medicare costs increasing by $192 (95% CI = $74, $311; p = .002) for each additional wave of language difficulties. Language difficulties (whether transient or persistent) were associated with substantial excess population healthcare costs in childhood, which are in addition to the known broader costs incurred through the education system. It is unclear whether healthcare costs were specifically due to the assessment and/or treatment of language difficulties, as opposed to conditions that may be co-morbid with or may cause language difficulties.

    The aim of this study was to determine the difficulties regarding the home care of children following haematopoietic stem cell transplantation (HSCT). The sample of the study includes the families of 73 children in a bone marrow transplant unit between 2010 and 2013, Turkey. Data were collected using a form included descriptive information and questions about the difficulties and complications of home care. Families were telephoned and problems they had encountered were recorded. Mann-Whitney U-test and the logistic regression analysis were used. The average age of the children was 10.65 ± 5.03 years, the average age was 8.89 ± 4.9 when HSCT was performed, and the average year after HSCT was 1.79 ± 0.74. 41.1% of the children underwent transplantation with diagnoses of anaemia. Primary physical problems that were found after discharge from the hospital were fever (43.8%), decreased appetite (37%), rash (34.2%) and pain (26%). Socially, 43.8% of families reported that their children had difficulties with school. Primary difficulties regarding care and follow-up were reported as skin care (34.2%) and catheter care (33.3%). In the post-transplantation period, it is important to provide information about potential problems and care to patients and families in order to increase the quality of life.

    Full Text Available Abstract Background Schizophrenia is a significantly disabling disease that affects all major areas of life. There is a lack of comprehensive synthesis of research findings on the full extent of psychosocial difficulties (PSDs experienced by people living with schizophrenia. This paper provides a systematic review of the literature concerning PSDs and their associated factors in schizophrenia. PSDs were conceptualized in accordance with the International Classification of Functioning, Disability and Health (ICF as disabilities, in particular impairments of mental functions, activity limitations and participation restrictions. Methods An electronic search using MEDLINE and PsychINFO plus a manual search of the literature was performed for qualitative and longitudinal studies published in English between 2005 and 2010 that examined PSDs in persons with schizophrenia. The ICF was used as a conceptual framework. Results A total of 104 papers were included. The most frequent PSDs addressed in the literature were not specific ones, directly linkable to the ICF categories of mental functions, activity limitations or participation restrictions, but broad areas of psychosocial functioning, such as psychopathological symptoms (53% of papers or global disability and functioning (37%. Among mental functions, the most extensively studied were cognitive functions (27% and emotional functions (27%. Within the domain of activities and participation, the most widely investigated were difficulties in relationships with others (31% and employment (20%. Of the factors associated with the intensity or course of PSDs, the most commonly identified were treatment modalities (56%, psychopathological symptoms (26%, and socio-demographic variables (24%. Medication tended to improve the most relevant PSD, but at the same time was the only consistently reported determinant of onset of PSDs (emerging as unwanted side-effects. Conclusions The present review illustrates the

    Adolescents with specific language impairment (SLI) are at a greater risk of emotional and behavioral problems compared to their typically developing (TD) peers, but little is known about their self-perceived strengths and difficulties. In this study, the self-reported social, emotional and behavioral functioning of 139 adolescents with a history of SLI and 124 TD individuals at age 16 was examined. The self-report version of the Strengths and Difficulties Questionnaire (SDQ) was used to assess their prosocial behavior and levels of peer, emotional and behavioral difficulties. Associations of these areas of functioning with gender, verbal and non-verbal skills were also investigated. Adolescents with a history of SLI were more likely than their TD peers to report higher levels of peer problems, emotional symptoms, hyperactivity and conduct problems. The majority of adolescents in both groups (87% SLI and 96% TD), however, reported prosocial behavior within the typical range. Difficulty with peer relations was the strongest differentiator between the groups, with the odds of reporting borderline or abnormally high levels of peer problems being 12 times higher for individuals with a history of SLI. Adolescents with poorer receptive language skills were also more likely to report higher levels of emotional and behavioral difficulties. The findings of this study identify likely traits that may lead to referral to services. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

    University students who report a history of reading difficulties have been demonstrated to have poorer word reading and reading comprehension skills than their peers; yet, without a diagnosed learning disability, these students do not have access to the same support services, potentially placing them at academic risk. This study provides a comprehensive investigation of first-year academic achievement for students with a history of reading difficulties (n = 244) compared to students with no such history (n = 603). We also examine reported use of metacognitive reading and study strategies and their relations with GPA. Results indicate that students with a history of reading difficulties earn lower GPA and successfully complete fewer credits compared to students with no history of reading difficulty. These patterns varied somewhat by faculty of study. Students with a history of reading difficulties also reported lower scores across multiple metacognitive reading and study strategy scales, yet these scores were not associated with their academic performance. Together, these results demonstrate the importance of identifying students with a history of reading difficulties and that commonly used study strategy inventories have limited value in predicting their academic success.

Such difficulties have been periodically reported over several decades in studies on the language abilities of children with features of ADHD, yet a comprehensive review of the literature has been lacking. This review aims to integrate evidence from several lines of research from 1979 to the present on pragmatic language difficulties in children with ADHD or symptoms of ADHD. A comprehensive search of empirical literature on pragmatic language in children with ADHD or symptoms of ADHD was conducted using PsycINFO and PubMed databases and through following up relevant references cited in articles. Literature was reviewed with respect to the nature and extent of pragmatic language difficulties in ADHD. Thirty studies met the review inclusion criteria, including recent questionnaire studies, observational studies of children's communication patterns, and studies of higher-level language comprehension and production. The studies indicate a consistent profile of pragmatic language impairments in children with features of ADHD, particularly in the areas of excessive talking, poor conversational turn-taking, and lack of coherence and organization in elicited speech. Pragmatic language difficulties are common in children with features of ADHD. These difficulties are consistent with deficits in executive function that are thought to characterize ADHD, thus providing some support for the theory that executive function contributes to pragmatic language competency. As yet there is very little empirical evidence of specific relationships between particular aspects of pragmatic language and particular domains of executive function. Given the importance of pragmatic language competency for children's social and academic functioning, pragmatic language abilities should be considered during

    A general problem of optimal information acquisition for its use in decision making problems is considered. This motivates the need for developing quantitative measures of information sources' capabilities for supplying accurate information depending on the particular content of the latter. In this article, the notion of a real valued difficulty functional for questions identified with partitions of problem parameter space is introduced and the overall form of this functional is derived that satisfies a particular system of reasonable postulates. It is found that, in an isotropic case, the resulting difficulty functional depends on a single scalar function on the parameter space that can be interpreted -- using parallels with classical thermodynamics -- as a temperature-like quantity, with the question difficulty itself playing the role of thermal energy. Quantitative relationships between difficulty functionals of different questions are also explored.

    There is controversy about how to conceptualize sexual problems in women. Our purpose in this study was to compare ICD-10 diagnoses of sexual dysfunction in women with whether or not the woman perceived she had a sexual problem, her views on its origins, and its impact on her life. Participants (N = 401, M age, 37.8 years) were consecutive attendees to general practices in London, England. Our main measures were an ICD-10 diagnosis of sexual dysfunction and the woman's own perception of a sexual problem. Based on reported symptoms and behavior, 38% of women had at least one ICD-10 diagnosis of sexual dysfunction. Prevalence fell to 18% in women who also perceived they had a problem and to 6% in women who regarded the problem as moderate or severe. A total of 73 (18%) women were assigned an ICD-10 diagnosis and agreed that they had a problem, 80 (20%) were assigned a diagnosis but reported no problem, 78 (19%) had no diagnosis but reported a sexual problem, and 170 (42%) had no diagnosis and reported no problem. For women with sexual partners, reported sexual satisfaction was lowest in those assigned an ICD-10 diagnosis who also perceived they had a problem and highest in those with no diagnosis and no perceived problem. Relationship and emotional difficulties were the most common perceived causes of sexual difficulties, whether or not an ICD-10 diagnosis was assigned. There were three aspects to sexual difficulties in women. The first concerned symptoms and behavior that clinicians used to make a diagnosis, the second was the woman's own perception that she had a sexual difficulty, and the third was her level of sexual satisfaction. All three appear to be important and may explain why published prevalence rates of sexual dysfunction and associated factors are so conflicting.

    [This paper is part of the Focused Collection on Upper Division Physics Courses.] Learning advanced physics, in general, is challenging not only due to the increased mathematical sophistication but also because one must continue to build on all of the prior knowledge acquired at the introductory and intermediate levels. In addition, learning quantum mechanics can be especially challenging because the paradigms of classical mechanics and quantum mechanics are very different. Here, we review research on student reasoning difficulties in learning upper-level quantum mechanics and research on students' problem-solving and metacognitive skills in these courses. Some of these studies were multiuniversity investigations. The investigations suggest that there is large diversity in student performance in upper-level quantum mechanics regardless of the university, textbook, or instructor, and many students in these courses have not acquired a functional understanding of the fundamental concepts. The nature of reasoning difficulties in learning quantum mechanics is analogous to reasoning difficulties found via research in introductory physics courses. The reasoning difficulties were often due to overgeneralizations of concepts learned in one context to another context where they are not directly applicable. Reasoning difficulties in distinguishing between closely related concepts and in making sense of the formalism of quantum mechanics were common. We conclude with a brief summary of the research-based approaches that take advantage of research on student difficulties in order to improve teaching and learning of quantum mechanics.

    Pediatric airway management is a priority during anesthesia, critical care and emergency medicine. The purpose of this study is to validate bedside tests that predict airway management difficulty in anesthetized children. Children under 12 years of age were recruited in a cross-sectional study to assess the value of some anthropometric measures as predictors of laryngoscopic difficulty. The patients were divided into three groups by age. Weight, height, neck circumference, BMI (body mass index), inter incisors distance thyromental distance, sternomental distance, frontal plane to chin distance (FPCD) and the Mallampati index were determined and were correlated with the CML (Cormack & Lehane classification). The incidence of difficult laryngoscopy (CML 3 or 4) was 3.58%. Factors that were significantly associated with laryngoscopic difficulty included short inter incisors distance, high FPCD, thyromental distance, sternomental distance and the Mallampati index. The FPCD/weight index exhibited a higher area under the ROC curve than any other variable considered. This study confirms that the FPCD and the FPCD/weight ratio are the most consistent predictors of laryngoscopic difficulty in pediatric patients. For patients over 6 months of age, the IID also correlated with laryngoscopic difficulty. For children who were capable of obeying simple orders, the Mallampati test correlated better with laryngoscopic difficulty than did the Mallampati test with phonation. Our results strongly suggest that skilled professionals should perform airway management in children, especially in patients with a high FPCD or a high FPCD/weight ratio.

    Purpose Research suggests a relationship between caring for a child with cancer and psychological distress in caregivers. Less evident is the role which financial difficulties might play in this relationship. We sought to determine if caring for a child with cancer was related to clinically relevant depressive symptoms among parents, whether or not financial difficulties mediated this relationship, and if financial difficulties were independently associated with symptoms of depression among parents of children with cancer. Methods Data are from 215 parents of children diagnosed with cancer or brain tumors (n=75) and a comparison group of parents of healthy children (n=140). Multiple logistic regression analyses were used to assess the factors associated with reporting clinically relevant depressive symptoms. Results Caring for a child with cancer was associated with increased odds of clinically relevant depressive symptoms in parents (OR: 4.93; 95% CI: 1.97 – 12.30), controlling for covariates. The mediating effect of financial burden on this relationship was not statistically significant. However, among parents of children with cancer, negative financial life events increased the likelihood of reporting symptoms of depression (OR: 4.89; 95% CI: 1.26 – 18.96). Conclusions Caring for a child with cancer was associated with depressive symptoms for parents. Financial difficulties were the strongest correlate of these symptoms among parents of children with cancer. Our results suggest that it may not only be the burden of caring for the child with cancer, but also the associated financial difficulties that contribute to a higher likelihood of depressive symptoms in parents.

    Spasmodic dysphonia is defined as a focal laryngeal disorder characterized by dystonic spasms of the vocal cord during speech. We described a case of a 22-year-old male patient who presented complaining of idiopathic difficulty swallowing that suddenly developed 6 months ago. The patient also reported pharyngolaryngeal pain, throat discomfort, dyspnea, and voice change. Because laryngoscopy found no specific problems, an electrodiagnostic study and videofluoroscopic swallowing study (VFSS) were performed to find the cause of dysphagia. The VFSS revealed continuous twitch-like involuntary movement of the laryngeal muscle around the vocal folds. Then, he was diagnosed with spasmodic dysphonia by VFSS, auditory-perceptual voice analysis, and physical examination. So, we report the first case of spasmodic dysphonia accompanied with difficulty swallowing that was confirmed by VFSS.

    Objective: To make intensified analysis upon the existing difficulties in early detection for the infectious diseases outbreak in China and put forward some effective measures to improve it. Methods: Field investigation and in-depth interview were applied in 23 interviewees from different-level CDC. Results:The study findings suggest that although the timeliness of outbreak detection has been improved since SARS epidemic in China, some problems still exist, such as: ① lacking syndrome surveillance; ② report quality of infectious disease should be improved; ③ difficulties of identifying the cases at lower social economic status; ④ a definite financial compensation mechanism for the operation of web-based report system is absent; ⑤ insufficient information exchange among different branches. Conclusion:Some effective measures must be taken including developing syndrome surveillance system; affording more education and training for related staff; increasing payout on surveillance and establishing an information exchange platform for early detection of disease outbreak.

    Full Text Available Prospective teachers should already be aware of possible mistakes in the textbooks and have knowledge of textbooks selection procedure and criteria. These knowledge is tried to being gained to prospective teachers at the Subject Area Textbook Analysis Course. It is important to identify the difficulties they encountered and the skills they gained from the point of implementing effectively this lesson. To research these problems, a case study was realized with 38 student teachers from Department of Secondary Science and Mathematics Education Chemistry Teaching Program at the Karadeniz Technical University Faculty of Fatih Education. Results suggest that prospective teachers gained the knowledge of research, teaching life, writing report, and analyzing textbook. Also, it was determined that they had difficulties in group working, literature reviewing, report writing, analyzing textbook, and critical analysis.

    Full Text Available [This paper is part of the Focused Collection on Upper Division Physics Courses.] We report on several specific student difficulties regarding the second law of thermodynamics in the context of heat engines within upper-division undergraduate thermal physics courses. Data come from ungraded written surveys, graded homework assignments, and videotaped classroom observations of tutorial activities. Written data show that students in these courses do not clearly articulate the connection between the Carnot cycle and the second law after lecture instruction. This result is consistent both within and across student populations. Observation data provide evidence for myriad difficulties related to entropy and heat engines, including students’ struggles in reasoning about situations that are physically impossible and failures to differentiate between differential and net changes of state properties of a system. Results herein may be seen as the application of previously documented difficulties in the context of heat engines, but others are novel and emphasize the subtle and complex nature of cyclic processes and heat engines, which are central to the teaching and learning of thermodynamics and its applications. Moreover, the sophistication of these difficulties is indicative of the more advanced thinking required of students at the upper division, whose developing knowledge and understanding give rise to questions and struggles that are inaccessible to novices.

    2009-01-01

    As children with acquired brain injuries (ABI) mature to become adolescents they develop a range of previously undetected social and emotional difficulties, which are commonly associated with executive dysfunctions. The authors wanted to determine whether visual-spatial performance is subject to age-related improvement, whether such skills can differentiate between children with ABI and healthy children and whether visual-spatial performance is a correlate of socioemotional functioning. The 'Cube analysis' and 'Dot discrimination' tests from the 'Visual Object Space Perception (VOSP)' battery and the Strengths and Difficulties Questionnaire (SDQ) were administered for 18 children, 9-15 years, with ABI and compared against 67 'healthy' children. Cube analysis scores improved significantly at approximately 10 years old in the control group. The ABI group performed the task significantly poorer than controls. Analysis indicated that visual discrimination skill did not account for performance difficulties. Visual-spatial performance was correlated with greater impact of reported difficulties on the SDQ. Visual-spatial tests are sensitive in differentiating between healthy children and children with ABI. Impairment of visuo-spatial skills may provide an index of psychosocial risk during later teenage years and adulthood.

    Full Text Available Introduction. After a mild traumatic brain injury (mTBI, individuals quickly resume driving. However, relatively little is known about the impact of mTBI on driving ability and, notably, on the perceived influence of postconcussive symptoms on driving. Hence, the objective of this study was to document the perception of driving abilities in individuals with mTBI. Method. Twenty-seven drivers with mTBI were interviewed to document their perception regarding their driving abilities. Both driving-related difficulties and compensatory strategies used to increase driving safety were documented. A mixed quantitative and qualitative analysis of the data was completed. Results. 93% of participants reported at least one difficulty perceived as having an impact on everyday activities. Most frequently named problems affecting driving were fatigue and reduced concentration. In addition, 74% of participants had adapted their driving or developed strategies to compensate for driving difficulties. Discussion/Conclusion. Postconcussive symptoms have repercussions on driving ability. However, people with mTBI tend to be aware of their difficulties and develop, over time, adaptive strategies. Preventive measures are thus warranted to increase health care professionals' awareness of the potential consequences of mTBI on driving ability and to promote guidelines for the safe resumption of driving after injury.

    Full Text Available Abstract Background The Strengths and Difficulties Questionnaire (SDQ is a practical, economic and user-friendly screening instrument of emotional and behavioural problems in children and adolescents. This study was aimed primarily at evaluating the factor structure of the Greek version of the SDQ. Methods A representative nationwide sample of 1,194 adolescents (11 to 17 years old completed the questionnaire. Confirmatory factor analysis (CFA was conducted to assess the factor structure of the SDQ. Results CFA supported the original five-factor structure. The modification of the model provided some improvements. Internal consistency was acceptable for total difficulties, emotional symptoms and prosocial behaviour scale, moderate for hyperactivity/inattention scale and inadequate for peer and conduct problems scale. Older adolescents (aged 15 to 17 years reported more hyperactivity/inattention and conduct problems than younger ones (aged 11 to 14 years and girls reported more emotional symptoms and less prosocial behaviour problems than boys. Adolescents of low socioeconomic status (SES reported more difficulties than those of medium and high SES. Conclusion The Greek SDQ could be potentially considered as a community-wide screening instrument for adolescents' emotional and behavioural problems.

    Full Text Available Black mulberry (Morus nigra is a fruit not known only for its nutritional qualities and its flavour, but also for its traditional use in natural medicine as it has a high content of active therapeutic compounds. However, this fruit is not widely produced in Spain but some trees are still found growing in the Canary Islands, particularly on the edges of the ravine. The inhabitants of these islands (Tenerife, La Gomera, La Palma, El Hierro and Lanzarote collect the fruit and prepare homemade beverages for medicinal purposes. Numerous authors have reported that type II diabetes mellitus can be controlled by taking a mixture containing black mulberry and water. Apart from that, this fruit has been used for the treatment of mouth, tongue and throat inflammations. In this study we present some characteristics of black mulberry juice (TSS, pH, titratable acidity, citric acid, lactic acid, polyphenols, anthocyanins, the potassium etc. and alcoholic beverages (alcoholic grade, pH, total acidity, volatile acidity, tannins, phenols etc. obtained from black mulberry. Moreover, we have studied the quality of liquors obtained from black mulberry in Canary Islands.

    Representation is a very important communication tool to communicate scientific concepts. Biologists produce phylogenetic representation to express their understanding of evolutionary relationships. The phylogenetic tree is visual representation depict a hypothesis about the evolutionary relationship and widely used in the biological sciences. Phylogenetic tree currently growing for many disciplines in biology. Consequently, learning about phylogenetic tree become an important part of biological education and an interesting area for biology education research. However, research showed many students often struggle with interpreting the information that phylogenetic trees depict. The purpose of this study was to investigate undergraduate students’ difficulties in reading and constructing a phylogenetic tree. The method of this study is a descriptive method. In this study, we used questionnaires, interviews, multiple choice and open-ended questions, reflective journals and observations. The findings showed students experiencing difficulties, especially in constructing a phylogenetic tree. The students’ responds indicated that main reasons for difficulties in constructing a phylogenetic tree are difficult to placing taxa in a phylogenetic tree based on the data provided so that the phylogenetic tree constructed does not describe the actual evolutionary relationship (incorrect relatedness). Students also have difficulties in determining the sister group, character synapomorphy, autapomorphy from data provided (character table) and comparing among phylogenetic tree. According to them building the phylogenetic tree is more difficult than reading the phylogenetic tree. Finding this studies provide information to undergraduate instructor and students to overcome learning difficulties of reading and constructing phylogenetic tree.

  3. Investigating Student Difficulties with Time dependence of Expectation Values in Quantum Mechanics

    Quantum mechanics is challenging even for advanced undergraduate and graduate students. In the Schr\\"odinger representation, the wave function evolves in time according to the time dependent Schr\\"odinger equation. The time dependence of the wave function gives rise to time dependence of the expectation value of observables. We have been exploring the difficulties that advanced undergraduate and graduate students have with time dependence of expectation values in quantum mechanics. We have developed and administered conceptual free response and multiple-choice questions to students to investigate these difficulties. We also interviewed 23 students individually using a think-aloud protocol to obtain a better understanding of the rationale behind students' written responses. We find that many students struggle with time dependence of expectation values of observables. We discuss some findings.

Of the qualitative descriptive research methods, the semi-structured interview technique was applied in the research. In accordance with the aim, teacher opinions about the statistics subjects were examined and analysed. Similar responses from the teachers were grouped and evaluated. The teachers stated that it was positive that middle school statistics subjects were taught gradually in every grade but some difficulties were experienced in the teaching of this subject. The findings are presented in eight themes which are context, sample, data representation, central tendency and dispersion measure, probability, variance, and other difficulties.

  5. Identifying attributes of GPU programs for difficulty evaluation

    2014-08-01

    Full Text Available General-purpose computation on graphics processing units (GPGPU has great potential to accelerate many scientific models and algorithms. However, some problems are considerably more difficult to accelerate than others, and it may be challenging for those new to GPGPU to ascertain the difficulty of accelerating a particular problem. Through what was learned in the acceleration of three problems, problem attributes have been identified that can assist in the evaluation of the difficulty of accelerating a problem on a GPU. The identified attributes are a problem's available parallelism, inherent parallelism, synchronisation requirements, and data transfer requirements. We envisage that with further development, these attributes could form the foundation of a difficulty classification system that could be used to determine whether GPU acceleration is practical for a candidate GPU acceleration problem, aid in identifying appropriate techniques and optimisations, and outline the required GPGPU knowledge.

    A dimensional approach was used to create bottom-up constructed subgroups that captured the behavioral heterogeneity in 36 Dutch-speaking children with language difficulties. Four subgroups were delineated based upon differences in cognitive ability, symbol understanding, joint attention and autism spectrum disorder related characteristics. Children with a different developmental disorder were found within a single cluster. Therefore, the results of this study suggest that bottom-up constructed subgroups might capture the heterogeneous behavioral profiles of young children with developmental difficulties in a more meaningful way. Furthermore, joint attention and symbol understanding seem important skills to assess in young children presenting with language difficulties. Copyright © 2013 Elsevier Ltd. All rights reserved.

  7. Orthogonally Evolved AI to Improve Difficulty Adjustment in Video Games

    (i.e. agents subject to fewer generations of evolution) make for easier opponents, while highly-evolved agents are more challenging to overcome. In this publication we test a new approach for difficulty adjustment in games: orthogonally evolved AI, where the player receives support from collaborating...... agents that are co-evolved with opponent agents (where collaborators and opponents have orthogonal incentives). The advantage is that game difficulty can be adjusted more granularly by manipulating two independent axes: by having more or less adept collaborators, and by having more or less adept...... opponents. Furthermore, human interaction can modulate (and be informed by) the performance and behavior of collaborating agents. In this way, orthogonally evolved AI both facilitates smoother difficulty adjustment and enables new game experiences....

    2005-01-01

    The purpose of this study was to assess pre-matriculation academic and demographic data to identify risk factors for academic difficulty and failure to graduate among veterinary students. Admissions data were compiled for 1,098 students admitted to veterinary college between 1989 and 2000 inclusive. Students were classified by (a) academic success, consisting of students who completed veterinary school within four years in the top 90% of the class or (b) academic difficulty, including students dismissed for academic reasons, students who experienced academic delay, and students who graduated with a cumulative GPA in the 10th percentile of their class. Of 1,098 admitted students, 930 (84.7%) completed veterinary school within four years in the top 90% of their class. Among students with academic difficulty, 94 (8.6%) completed veterinary school in four years in the 10th percentile, 44 (4%) experienced academic delay, and 30 (2.7%) were dismissed. Academic difficulty was associated with a low prerequisite GPA, a low GRE score, poor undergraduate institutional selectivity, and older age (> or =35 years). Students who attended three-or-more undergraduate institutions or two-year colleges prior to attending a four year institution were 1.9 times more likely to experience academic difficulty and 3.87 times more likely to fail to graduate than students who attended a four-year institution (major or small) to complete their prerequisites. These study findings may assist with early identification of students at greater risk of experiencing academic difficulty and support the consideration of cognitive selection criteria (GRE and GPA) and undergraduate institutional experience during the admissions process.

    Randomized controlled clinical trials (RCTs) are considered to be the gold standard for evidence-based medicine nowadays, and are important for directing medical practice through consistent scientific observations. Steps such as patient selection, randomization and blinding are fundamental for conducting a RCT, but some additional difficulties are presented in trials that involve surgical procedures, as is common in orthopedics. The aim of this article was to highlight and discuss some difficulties and possible limitations on RCTs within the field of surgery. PMID:27027037

    Certain aspects of numerical processing show a connection with spatial abilities. Spatial abilities may be enhanced through the practice of origami. It is possible that the development of spatial abilities will support the development of numerical processing. The goal was to investigate whether spatial and numerical skills can be developed using origami and the folding of three-dimensional shapes. During the course of the 10-wk. training program, consisting of weekly 60-min. sessions, the performance of children with mathematical difficulties showed considerable improvement in spatial and numerical tasks as compared to the control group of children with mathematical difficulties.

    Due to an absence of communication training, provider responses to patient/family spiritual distress are highly variable. Assessing spiritual and forgiveness concerns are important to ensuring quality holistic care. Cross-sectional survey data were collected from providers attending 1 of 2 continuing education courses. The survey measured the frequency and initiation of communication about spirituality and forgiveness with patients/families, the perceived difficulty in communication across topics, and preparation and resources for these discussions. Most participants (n = 124) were nurses followed by social workers with over half of providers having 10 years or more of clinical experience. Participants reported the highest level of difficulty in spiritual communication when talking with family after the death of a patient, followed by conducting a spiritual history with a patient. Facilitating forgiveness communication between parent and adult child, followed by facilitating forgiveness between partners was most difficult for all participants. Social workers reported much lower difficulty than nurses on all items of spiritual and forgiveness communication. The majority of participants indicated they were involved in spiritual and forgiveness communication. The most difficult communication included talking with family after death and facilitating forgiveness between patients and families. These findings support the importance of spiritual communication in clinical practice, and the need for clinician training in communicating about spirituality and forgiveness with patients and families. © The Author(s) 2015.

    Previous longitudinal studies have demonstrated that poor sleep may precede depression and anxiety. The current study examined the association between self-reported sleeping difficulties and new onset depression and anxiety in young women. A nationally representative sample of 9,683 young women from the Australian Longitudinal Study of Women's Health was analyzed. Women were surveyed in 2000 (aged 22 to 25 years), 2003, 2006, and 2009. Generalized estimating equations were used to examine the association between sleeping difficulties in 2000 and new-onset depression (excluding postnatal depression) and anxiety at each subsequent survey. Significant increased risk of new onset depression (odds ratio (OR)=2.6 in 2003; OR=4.4 in 2006; OR=4.4 in 2009) and anxiety (OR=2.4 in 2006; OR=2.9 in 2009) was found at each follow-up survey in women who reported sleeping difficulties "often" in 2000. Further research is needed to uncover the mechanisms underlying the link between sleep problems and mental health.

    Full Text Available Although medical facilities restrict smoking inside, many people continue to smoke outside, creating problems with second-hand smoke, litter, fire risks, and negative role modeling. In 2005, Arkansas passed legislation prohibiting smoking on medical facility campuses. Hospital administrators (N=113 were surveyed pre- and post-implementation. Administrators reported more support and less difficulty than anticipated. Actual cost was 10-50% of anticipated cost. Few negative effects and numerous positive effects on employee performance and retention were reported. The results may be of interest to hospital administrators and demonstrate that state legislation can play a positive role in facilitating broad health-related policy change.

    questions on specific difficulties in the procedure of identifying child abuse. RESULTS: The main difficulties noted by the pediatricians were disbelief in the effectiveness of the Child Support Service, non-existence or inadequate training on child-abuse issues by the pediatricians, and personal limitations. These difficulties are the same reported by the literature. Furthermore, professionals thought that in order to report the case, confirmation of the suspected abuse is needed, which contradicts the law. CONCLUSIONS: There was a lack of professional training to deal with victims of violence leading to ignorance about how to proceed in such cases. The current biomedical model is an obstacle for identifying possible cases because their signs and symptoms can be confused with other differential diagnoses. It is necessary to train pediatricians about diagnosis and procedures regarding child abuse as well as to evaluate the effectiveness of this training.

  17. Direct and indirect aggression and victimization in adolescents - associations with the development of psychological difficulties.

    2014-01-01

    Previous research has established that direct and indirect forms of aggression differ in their association with gender and type of psychological difficulties. One purpose of the present study was to test if the same applies to direct and indirect victimization. A second purpose was to study these associations not only cross-sectionally (as in most previous research) but also longitudinally. A third purpose was to test the hypotheses that there are prospective bidirectional associations not only between victimization and psychological difficulties (which has been shown in previous research), but also between aggression and psychological difficulties, and that direct and indirect forms of aggression and victimization show different associations with different types of psychological difficulties. The participants were a community sample of all students in two grades of regular school in a Swedish municipality who answered questionnaires as part of a two-wave longitudinal study with a one-year interval. The participants were 13-15 years old, and there were longitudinal data on 893 students, which represented 85% of all students. The cross-sectional associations were primarily tested by semi-partial correlations, and the longitudinal associations by hierarchical multiple regression. The results corroborated the meaningfulness of differentiating not only between direct and indirect aggression but also between direct and indirect victimization. Boys reported being more victim to direct aggression, whereas girls reported being more victim to indirect aggression. Direct aggression predicted increased conduct problems in boys, whereas indirect aggression predicted increased conduct problems in girls, and conduct problems reciprocally predicted increased direct and indirect aggression. Indirect victimization showed prospective bidirectional associations with emotional symptoms and conduct problems, suggesting the potential development of vicious cycles of escalating problems

    2003-01-01

    Mathematical competencies of 180 children were examined at 4 points between 2nd and 3rd grades (age range between 7 and 9 years). Children were initially classified into one of 4 groups: math difficulties but normal reading (MD only), math and reading difficulties (MD-RD), reading difficulties but normal math (RD only), and normal achievement in math and reading (NA). The groups did not differ significantly in rate of development. However, at the end of 3rd grade the MD only group performed better than the MD-RD group in problem solving but not in calculation. The NA and RD only groups performed better than the MD-RD group in most areas. Deficiencies in fact mastery and calculation fluency, in particular, are defining features of MD, with or without RD.

    This research verified adherence and knowledge of people with depression regarding prescribed pharmacotherapy, satisfaction with the health team and difficulties related to drug treatment. This is descriptive and cross-sectional study, with quail-quantitative approach. The study included 27 people assisted in an outpatient clinic in the interior of the state of São Paulo - Brazil. Data were collected through semi-structured interviews and review of medical records and analyzed using descriptive statistics and content analysis. It was found that 29.6% of patients were no adherent to medication and 51.9% were unaware of the dose of prescribed drugs. Impact of drug therapy in depressive symptoms on self-care, dissatisfaction with effects of psychoactive drugs, lack of support, use of multiple medications and lack of knowledge about the disorder and treatment were reported as difficulties in following drug therapy. This study shows critical factors to the promotion of patient safety in following drug therapy.

    2014-08-01

    The rate of unemployment among homeless people is estimated to exceed 80%. A high prevalence of mental illness partially explains this figure, but few studies about the relationship between employment and homelessness have focused on homeless people with mental illness. The present study explores the self-reported barriers to employment in a sample of individuals with mental illness when they were homeless. A sample of 27 individuals with mental illness and recent experiences of homelessness, who had expressed an interest in working, participated in semi-structured qualitative interviews. Inductive analysis was used to identify barriers to employment. The prominent barriers include: (1) current substance abuse, (2) having a criminal record, (3) work-impeding shelter practices, and (4) difficulties obtaining adequate psychiatric care. Individuals who have been homeless and have a mental illness report facing specific barriers associated with mental illness, homelessness, or the interaction between the two. Additional research should explore how supported housing and employment interventions can be tailored to effectively serve this group.

    2013-01-01

    Cognitive assessments and behavioral ratings of attention were used to examine the relation of inattention to math performance in children. Third grade students with math difficulties (MD; n = 17) and math and reading difficulties (MDRD; n = 35) were administered the Attentional Network Test (ANT), as well as achievement and intelligence measures. Strengths and Weaknesses of ADHD-Symptoms and Normal-Behavior-IV (SWAN-IV) Inattention ratings were collected from teachers. Two comparison groups were also recruited: a typically achieving group (n = 23) and a group that responded to a math-tutoring intervention (responders; n = 54). On the ANT, children with MD and MDRD did not perform significantly different than typically achieving children or responders on measures of alerting and orienting attention and executive control. All subgroups did demonstrate performance patterns that were expected on the ANT. However, performance across blocks of the task was inconsistent, suggesting poor reliability. There were no relations between ANT performance and SWAN-IV behavioral inattention scores, though behavioral ratings of inattention correlated significantly with math performance. Children with MD and MDRD may have more difficulty with distraction and attention to detail in contextual situations, as opposed to impulsive responding in these settings. The lack of relation between cognitive attention and math performance may suggest that either the ANT does not assess the relevant attention constructs associated with math difficulties or may parallel studies of attention deficit/hyperactivity disorder (ADHD) in which cognitive and behavioral assessments are weakly related.

    2016-05-01

    Visual-verbal paired associate learning (PAL) refers to the ability to establish an arbitrary association between a visual referent and an unfamiliar label. It is now established that this ability is impaired in children with dyslexia, but the source of this deficit is yet to be specified. This study assesses PAL performance in children with reading difficulties using a modified version of the PAL paradigm, comprising a comprehension and a production phase, to determine whether the PAL deficit lies in children's ability to establish and retain novel object-novel word associations or their ability to retrieve the learned novel labels for production. Results showed that while children with reading difficulties required significantly more trials to learn the object-word associations, when they were required to use these associations in a comprehension-referent selection task, their accuracy and speed did not differ from controls. Nevertheless, children with reading difficulties were significantly less successful when they were required to produce the learned novel labels in response to the visual stimuli. Thus, these results indicate that while children with reading difficulties are successful at establishing visual-verbal associations, they have a deficit in the verbal production component of PAL tasks, which may relate to a more general underlying impairment in auditory or phonological processing.

    2006-01-01

    In the present study, we identified patients who had difficulties learning the minimum knowledge and skills required to carry out peritoneal dialysis (PD), and we compared the outcomes in this subgroup of patients with outcomes in the general PD population. We calculated the mean learning sessions needed by our total PD population during the training period. We then assigned patients to one of two groups according to the number of learning sessions they needed. Patients who required a number of sessions equal to or less than the mean were placed in the "standard learning" group; patients who required more sessions but who reached the minimum knowledge and skills were placed in the "learning difficulties " group. We compared these two groups in terms of age, sex, diabetes status, autonomy to perform PD, family support, education level, residual renal function, and Charlson comorbidity index. Outcomes on PD included time to first peritonitis episode, peritonitis rate, percentage of patients free of peritonitis during follow-up, survival time on PD, and transfer to hemodialysis. Patients with learning difficulties were older and had more comorbidities. Outcomes on PD in the learning difficulties group were similar to those in the standard learning group, except for time to first peritonitis.

    Assessing the workload of surgeons requires technology to continuously monitor surgeons' behaviors without interfering with their performance. We investigated the feasibility of using eye-tracking to reveal surgeons' response to increasing task difficulty. A controlled study was conducted in a simulated operating room, where 14 subjects were required to perform a laparoscopic procedure that includes 9 subtasks. The subtasks could be divided into 3 types with different levels of task difficulty, calculated by the index of task difficulty (ID) proposed by Fitts in 1954. Pupillary responses of subjects in performing the procedure were recorded using Tobii eye-tracking equipment. Peak pupil dilation and movement time were compared between subtasks with different IDs as well as between fast moving and slow aiming phases within each subtask. When the task difficulty was increased, task completion time increased. Meanwhile, the subjects' peak pupil size also increased. As the entire procedure was performed continuously, we found that pupil responses were not only affected by the ID in the current subtask but also influenced by subtasks before and after. Decomposing a surgical procedure into meaningful subtasks and examining the surgeon's pupil response to each subtask enables us to identify the challenging steps within a continuous surgical procedure. Psychomotor evidence on surgeon's performance may lead to an innovation for designing a task-specific training curriculum. © The Author(s) 2015.

    Full Text Available Pregnancy causes physical and psychological changes in women, which directly affect the spouse. Thus, this study aimed at investigating the difficulties experienced by men during pregnancy, describing male reactions when facing such difficulties. This is an exploratory and descriptive study with a qualitative approach, developed in Natal / RN, Brazil. Data collection occurred from May to July 2008, with 27 men, through semi-structured interviews, after authorization n ° 176/2008 issued by the Ethics Committee of the Rio Grande do Norte Federal University. The interviews were elaborated according to Bardin’s Content Analysis. Results suggest that mood changes in pregnant women, alterations in marital life, financial hardship and access to health services are the main difficulties perceived by interviewed men. When facing such problems, respondents stated that they reacted calmly and understandingly. We concluded that the interviewees experienced difficulties resulting from their partners' pregnancy, but these did not represent an obstacle to their relationships within the family context.

    Bone/joint pain and difficulty with sexual arousal are prevalent, frequently severe, and potentially treatable in patients on maintenance hemodialysis. However, the mediators and adequacy of treatment for these symptoms have been less well studied. We sought to assess the clinical correlates and treatment of these symptoms in patients receiving chronic hemodialysis. Using the Dialysis Symptom Index, we assessed the presence and severity of bone/joint pain and difficulty with sexual arousal in 75 patients on chronic hemodialysis. Associations of demographic and clinical variables with these 2 symptoms were assessed. We also recorded the use of analgesics for bone/joint pain and, among men, phosphodiesterase-5 inhibitors for difficulty with sexual arousal. Twenty-eight patients (37%) reported bone/joint pain, of whom 20 (71%) described it as moderate to severe. Nineteen of 50 male patients (38%) reported difficulty with sexual arousal, which was described as moderate to severe by 15 (79%). Patients' demographic and clinical characteristics were not correlated with bone/joint pain. Among men, there were no correlations between patients' demographic and clinical characteristics and difficulty with sexual arousal. Only 48% of patients with bone/joint pain were receiving analgesics, while 21% of men who described difficulty with sexual arousal were receiving phosphodiesterase-5 inhibitors. Demographic, clinical, and dialysis-related variables are poorly correlated with bone/joint pain and difficulty with sexual arousal. However, these symptoms are prevalent and under-treated, which should spur efforts to assess the impact of improving provider assessment and treatment of these symptoms on patient outcomes, including health-related quality of life.

    Project-Based Learning (PBL) is considered to be an active learning methodology which can be used to develop both technical and transversal competences in engineering programs. This methodology demands a great deal of work effort from the students and also from the teachers and it requires a meticulous plan and a well-managed project as well. These activities go far beyond the normal activities in traditional lectures, enabling to outpace the difficulties that spur along the way that may be both complex and demotivating. This methodology has been implemented in the Integrated Master Degree on Industrial Engineering and Management (IEM), at one public university in Portugal, since the 2004/2005 academic year. The aim of this paper is to identify and discuss the main difficulties of the implementation of PBL, mainly from the teachers’ perspectives. Additionally, some effective strategies will be recommended to overcome such difficulties. Design/methodology/approach: The perceptions of the teachers were collected through a survey based on six main themes. The participants in the study include eight teachers from the five courses of the first semester of the first year of the IEM program involved in the 2012/2013 and 2013/2014 editions. Findings: Integration of courses in the project; student assessment; growing number of students in each team and the need of physical spaces for them; and compartmentalized knowledge has emerged as the main difficulties. To overcome these difficulties some key strategies were recommended. Originality/value: A new perspective based on course teachers' views and experiences will deepen the understanding of the problems and provide inputs for the development of strategies that may improve the effectiveness of PBL and introduce changes for its successful implementation. These strategies are intended to be transferable to other contexts, as most of the problems and constraints are common to other active learning approaches. (Author)

  8. Identifying Features of Fitness Landscapes and Relating Them to Problem Difficulty.

    Moser, I; Gheorghita, M; Aleti, A

    2016-02-29

    Complex combinatorial problems are most often optimised with heuristic solvers, which usually deliver acceptable results without any indication of the quality obtained. Recently, predictive diagnostic optimisation was proposed as a means of characterising the fitness landscape while optimising a combinatorial problem. The scalars produced by predictive diagnostic optimisation appear to describe the difficulty of the problem with relative reliability. In this study, we record more scalars that may be helpful in determining problem difficulty during the optimisation process and analyse these in combination with other well-known landscape descriptors by using exploratory factor analysis on four landscapes that arise from different search operators, applied to a varied set of quadratic assignment problem instances. Factors are designed to capture properties by combining the collinear variances of several variables. The extracted factors can be interpreted as the features of landscapes detected by the variables, but disappoint in their weak correlations with the result quality achieved by the optimiser, which we regard as the most reliable indicator of difficulty available. It appears that only the prediction error of predictive diagnostic optimisation has a strong correlation with the quality of the results produced, followed by a medium correlation of the fitness distance correlation of the local optima.

    Full Text Available The main purpose of this research was to survey the chief fifficulties found by MAPA in the implementation of traceability, also aiming to elaborate indicators, suggest proposals to solve such difficulties and contribute for the formulation of national policies. A semi-structured qualitative questionnaire, containing multiple choice questions, both open and mixed, was used. That questionnaire was sent to the certifying firms accredited by MAPA. The data obtained were tabulated by utilizing the EpiData® 3.1 software, with automatic control of range and consistency of data and afterward, analyzed by means of means of descriptive statistics, making use of the statistical software SPSS for Windows® - version 17.0. The frequent changes in the norms of new SISBOV, the disinterest and the lack of awareness of the cattle raisers for traceability were the main difficulties faced by the certifiers. Transformations on the part of MAPA summed to the mobilization of the raisers through the spread and explanations are needed to solve such difficulties. The need for adequacies inherent to incoherence and outdating of the data bank of the certifiers accredited in MAPA is stressed further.

  10. Importance and difficulties of cooperative learning application in class teaching from teachers' perspective

    2016-01-01

    Full Text Available Based on previous knowledge of cooperative learning two approaches stand out in researching the importance of cooperative learning: a the first approach tries to examine the effects, conditions and mechanisms by which educational outcomes are realized in the application of cooperative learning; and b the second approach moves the focus towards attitudes and perceptions of teachers and students on the relevance of cooperative learning. By applying descriptive-analytical technique we conducted a research aimed at examining the opinions of teachers (N=305 about the importance and difficulties in application of cooperative learning in the context of class teaching. The results show that the teachers had positive attitudes towards the importance of cooperative learning for reaching various educational goals and socio-affective and cognitive development of students. It turned out that the opinions of the teachers were not determined by the level of their education or work experience. Additionally, it turned out that the teachers' opinions about the difficulties of application in class are due more to work organization and were not assessed from the aspect of knowledge, attitudes and convictions of the participants in the teaching process. The obtained results, although generally encouraging for teaching practice indicate a need for further advancement of this segment of the teacher's work in order to understand better the value of cooperative learning and consider more critically the difficulties for its application in classroom.

Methods One hundred and thirty four subjects (aged 7-14 years with reading difficulties were referred from an educational institute in Vienna, Austria for visual assessment. Each child was given either 8Δ base-in reading spectacles (n = 51 or computerised home vision therapy (HTS (n = 51. Thirty two participants refused all treatment offered (clinical control group. A full visual assessment including reading speed and accuracy were conducted pre- and post-treatment. Results Factorial analyses demonstrated statistically significant changes between results obtained for visits 1 and 2 for total reading time, reading error score, amplitude of accommodation and binocular accommodative facility (within subjects effects (p Conclusions Reading difficulties with no apparent intellectual or psychological foundation may be due to a binocular vision anomaly such as convergence insufficiency. Both the HTS and prismatic correction are highly effective treatment options for convergence insufficiency. Prismatic correction can be considered an effective alternative to HTS.

    Full Text Available Objectives: To identify communication difficulties faced by the nursing staff and to learn the strategies developed for non-oral communication. Methods: This is a descriptive, exploratory, level I study with a quantitative approach. The sample group comprised 37 registered nurses and 63 licensed practical nurses of a private hospital who, after undergoing the ethical-legal procedures, answered a questionnaire to identify difficulties faced and strategies used in the care for hearing-impaired patients. Results: Difficulty in explaining matters of interest to the patient was reported by 66% of professionals; and 32% reported difficulties in understanding patients in their way of communicate. The strategy adopted by 100% of respondents was mimicry, followed by lip reading, used by 94% of respondents; help from a person accompanying the patient was used by 65%, and written communication by 42% of respondents. Only 1% used communication via the Brazilian Sign Language (LIBRAS. Conclusions: The difficulties found and the strategies adopted by the nursing staff in communicating with hearing-impaired patients justify the need to train these professionals to deliver a more humanized care, developing a more inclusive society for those with special needs.

    2014-02-01

    Mealtime difficulties are common in typically developing young children. Easily accessible, wide-reaching, early intervention is needed to meet demand for assistance, and prevent the development of more serious feeding and psychosocial problems. Behavioural parent training is an efficacious intervention for childhood mealtime problems, however, existing programmes are long, intensive, and costly. The current study aimed to evaluate the efficacy of a brief parenting discussion group for young children's mealtime difficulties. Eighty-six parents of 2- to 5-year-old children with mealtime difficulties participated in a randomised controlled trial of Hassle Free Mealtimes Triple P (HFMTP; Morawska & Sanders, 2012), a 2-h discussion group on positive parenting strategies specific to the mealtime context. Results of parent-report measures showed that after intervention, there were significant improvements with large effect sizes in children's mealtime behaviour, parents' mealtime practices and cognitions, and both mealtime and general parenting confidence, compared to a waitlist control group. Parents also reported high satisfaction with the programme and effects were maintained at 6-month follow-up. These results support the efficacy of a brief parenting discussion group for childhood mealtime difficulties. This low intensity format of intervention has the potential to meet the high demand for assistance with young children's mealtime difficulties.
