Assaying parathyroid hormone (PTH) in the washing liquid after fine-needle aspiration biopsy (FNAB) seems to be a valid approach to locate parathyroid tissue. PTH-FNAB was evaluated in 47 patients with a clinical picture of primary hyper-parathyroidism (PHP) and ultrasonography (US) suggestive of parathyroid lesion. The patients were subdivided into two groups on the basis of the absence or presence of US thyroid alterations. The result of PTH-FNAB was compared with those of cytology, scintigraphy and, in 24 patients, surgical outcome. PTH-FNAB samples with a value higher than that recorded in the serum and higher than our institutional cut-off were deemed to be probable samples of parathyroid tissue. Cytology proved diagnostic for benign thyroid lesions, non-diagnostic for thyroid lesions, hyperplastic parathyroid tissue, undetermined or malignant thyroid lesions and other lesions in 45%, 30%, 17%, 4%, and 4% of cases, respectively. In 47% of cases, PTH-FNAB indicated that the sample had been taken in parathyroid tissue. In patients without US alterations, the diagnostic accuracy of PTH-FNAB was greater than that of scintigraphy. After surgery, comparison between the results of PTH-FNAB and scintigraphy, in terms of positive predictive value (PPV), revealed the superiority of PTH-FNAB; PPV was 94% for FNAB and 71% for scintigraphy, while sen-sitivity was 83% and 69%, respectively. PTH-FNAB evaluation after FNAB appears to be more diagnostic than cytology and scintigraphy. Of all the procedures used, PTH-FNAB appears to be the method of choice when the target is US suggestive and reachable. PTH-FNAB appears to be a useful method of guiding surgical intervention.  相似文献   

A typology of students in intermediate vocational education and training programmes based on student engagement factors,sociodemographic characteristics and intentions of dropping out     

Antoni Cerda‐Navarro  Francesca Salva‐Mut  Ruben Comas Forgas 《European Journal of Education》2019,54(4):635-650

The main objective of this article is to define a typology of students enrolled in intermediate vocational education and training programmes in Spain. Students were first placed in groups based on various factors related to engagement. Then, their sociodemographic characteristics were analysed. Finally, the intentions of dropping out were considered in each of the groups. The results obtained describe a typology of students consisting of five groups with different levels of engagement. Each of the groups is associated with distinct sociodemographic characteristics and shows notable differences with regards to intentions of leaving their studies. The results of this research can serve to detect and prevent drop‐outs that take place at this level by identifying at‐risk profiles and creating more adequate approaches and interventions.  相似文献

Against the grain: Reading for the challenges of collaborative digital humanities pedagogy     

Francesca Giannetti 《College & Undergraduate Libraries》2017,24(2-4):257-269

ABSTRACT

This article provides a critical review of the past five years of literature in digital humanities pedagogy and faculty-librarian collaboration, commingled with reflections on personal practice, which extend findings from the literature. Faculty-librarian partnerships in DH pedagogy reflect a rapidly evolving area of engagement calling for expertise in teaching, subject knowledge, scholarly communication, digital technologies, and DH research methodologies. Although there is a rapidly expanding body of literature on these partnerships, the challenges of the work tend to be minimized. This article expands upon commonly encountered difficulties, and it points to potential solutions and best practices.  相似文献   

A comparison of updating processes in children good or poor in arithmetic word problem-solving   总被引：2，自引：0，他引：2  

Maria Chiara Passolunghi  Francesca Pazzaglia   《Learning and individual differences》2005,15(4):257-269

This study examines the updating ability of poor or good problem solvers. Seventy-eight fourth-graders, 43 good and 35 poor arithmetic word problem-solvers, performed the Updating Test used in Palladino et al. [Palladino, P., Cornoldi, C., De Beni, R., and Pazzaglia F. (2002). Working memory and updating processes in reading comprehension. Memory and Cognition, 29, 344–354.]. The participants listened to wordlists, each comprising 12 words referring to objects or animals of different sizes. At the end of each list participants were asked to recall the 3 or 5 words denoting the smallest objects/animals in the list. Results show that poor problem-solvers recalled fewer correct words and made more intrusion errors (recall of non-target words) than good problem-solvers. Results support the hypothesis that the ability to select and update relevant, and suppress irrelevant information, is related to problem-solving, even when the influence of reading comprehension is controlled for. With reference to Baddeley's, and other recent WM models [Miyake, A., and Shah, P. (Eds.), (1999). Models of working memory: Mechanisms of active maintenance and executive control. New York: Cambridge University Press.], our results point to the idea that problem-solving relies on the central executive for processing and updating information contained in the problems.  相似文献   

Writing and Publishing in a Blended Learning Environment to Develop Students’ Scholarly Digital Ethos     

Jay Fogleman  Mona Anne Niedbala  Francesca Bedell 《Behavioral & Social Sciences Librarian》2013,32(2):71-85

The explosive growth of clinical psychology literature has made it difficult for anyone to get a comprehensive overview of the field. Clinical psychology handbooks help alleviate this problem by providing a thorough survey of the discipline. Despite their utility for both students and librarians, no literature reviews of handbooks in clinical psychology currently exist. The present study seeks to fill this gap by selectively reviewing handbooks currently available, as well as a few "classics."  相似文献   

手工业与工业化技术:中印手工纺织业的比较     

白馥兰  董晓萍 《北京师范大学学报(社会科学版)》2017,(5)

手工业与现代技术工业化是国家生产模式的二元结构,在跨文化的视野下分析这种二元结构的发展趋势,总结得失利弊,对于考量国家现代化政策水平不无裨益。中印手工纺织业的比较正是这方面的一个研究个案。中印两国政府都曾以同样的决心改革传统手工业生产,提高现代工业化水平,加速国家现代化。两国也有差异,新中国初期实行手工业改造,鼓励工人和农民转向工业技术就业;印度则限制农村手工业的转型,在城市实施大规模的工业化。这两种努力的长期结果是大不相同的,在中国,手工业生产已缩减至小众范围,中国在现代化经济繁荣后发展起来的旅游文化产业和遗产保护工作催生了新的手工业品。在印度,目前仍有数以千万计的家庭在从事手工纺织业的劳作,支持和保护手工业及其价值观成为一种强大的政治号召,推动人们为维护社会公正和环境保护而奋斗。解读这一个案具有启示意义。  相似文献   

Individually Weighted-Average Models: Testing a Taxonomic SEM Approach Across Different Multidimensional/Global Constructs Because the Weights “Don’t Make No Nevermind”     

Herbert W. Marsh  L. Francesca Scalas 《Structural equation modeling》2018,25(1):137-159

From the time of William James, psychologists have posited individually importance-weighted-average models (IWAMs) in which weighting specific attributes by individual measures of importance improves prediction of the global outcome measures. Because IWAMs cause much confusion, we briefly review a general taxonomic paradigm and structural equation models for testing IWAMs, and demonstrate its application for 2 simulated and 3 diverse “real” data applications (multidimensional measures of self-concept, quality of life, and job satisfaction). Consistent across the real data applications and previous research more generally, there is surprisingly little support for IWAMs when tested appropriately. In these diverse tests of IWAMs we integrate new approaches such as exploratory structural equation modeling (SEM), alternative approaches to constructing latent interactions, application of bifactor models, modeling method and item-wording effects, and the juxtaposition of model evaluation in relation to goodness of fit (typically used in SEM studies) and variance explained (typically used in multiple regression tests of IWAMs).  相似文献   

NEETs in Spain: an analysis in a context of economic crisis     

Francesca Salvà-Mut  María Tugores-Ques  Elena Quintana-Murci 《International Journal of Lifelong Education》2018,37(2):168-183

This article presents the research results from a study that was conducted on Spanish youths aged 25–29 years who are neither in employment nor education and training (NEET). Their characteristics were analysed as well as the differential aspects in relation to people who are in employment, education or training. A typology of NEETs was also established based on their availability for and attitude towards employment, and the similarities and differences between the diverse subgroups were analysed. A mixed methodology was used: a quantitative perspective, which enabled a statistical and regression analysis using data that were obtained through questionnaires, and a qualitative perspective based on a biographical interview, which made it possible to focus on perceptions and processes. The results enable us to identify the common characteristics of the NEET population as well as the perceptions and determining factors of the three typologies.  相似文献   

The Role of Age and Verbal Ability in the Theory of Mind Task Performance of Subjects with Autism   总被引：30，自引：0，他引：30  

Francesca G. E. Happé 《Child development》1995,66(3):843-855

A number of studies have reported that most children with autism fail theory of mind tasks. It is unclear why certain children with autism pass such tests and what might be different about these subjects. In the present study, the role of age and verbal ability in theory of mind task performance was explored. Data were pooled from 70 autistic, 34 mentally handicapped, and 70 normal young subjects, previously tested for a number of different studies. The analysis suggested that children with autism required far higher verbal mental age to pass false belief tasks than did other subjects. While normally developing children had a 50% probability of passing both tasks at the verbal mental age of 4 years, autistic subjects took more than twice as long to reach this probability of success (at the advanced verbal mental age of 9-2). Possible causal relations between verbal ability and the ability to represent mental states are discussed.  相似文献
