Blood zinc protoporphyrin, serum total protein, and total cholesterol levels in automobile workshop workers in relation to lead toxicity: Our experience     

Suneesh Kumar Pachathundikandi  Earaly Thomas Varghese 《Indian journal of clinical biochemistry : IJCB》2006,21(2):114-117

Blood zinc protoporphyrin (ZPP), serum total protein (TP), and total cholesterol (TC) levels in automobile workshop workers in relation to lead toxicity were analysed. In the present study, automobile workshop workers (healthy male workers at an age between 28 and 35 from four major automobile workshops in Kottayam, Kerala State, India) and the control (male healthy adults at an age between 28 and 35 residing at Aymanam, a distant village at Kottayam District, Kerala having reduced or no chance of lead exposure) displayed significant difference in blood lead (BPb) and blood ZZP (BZPP) level. The mean value of BPb in automobile workshop workers was 15.76±0.33 μg/dl, while in the control it was 8.20±0.15 μg/dl. In automobile workshop workers, the mean value of BZPP was 34.2±0.62 μg/dl. The control group exhibited a mean of 11.5±0.22 μg/dl. Automobile workshop workers exhibited significant increase in BZPP was corresponding to the increase in BPb level. The total protein levels estimated in automobile workshop workers showed significant decrease compared to control individuals, but was within the reference range of healthy individuals. The mean value of TP level in automobile workshop workers and control was 6.9±0.13 g/dl and 7.71±0.18 g/dl, respectively. There was no significant difference in blood haemoglobin (BHb) level among the automobile workshop workers and control. The serum TC level in automobile workshop workers showed significant decrease compared to the control individuals, but was with in the reference range of healthy individuals. The mean level of serum TC in automobile workshop workers was 162.00±3.44 mg/dl and the same in control was 172.86±4.32 mg/dl. The present study affirms occupational lead toxicity in automobile workshop workers and its effect on serum protein and cholesterol levels.  相似文献   

Opportunity knocks     

Thomas B. Åstebro 《Research Policy》2005,34(9):1404-1418

Research on technological opportunity has typically focused on the impact of broad industry characteristics on R&D intensity of firms. This study complements such approaches by examining the impact of a multidimensional vector that measures technological opportunity on independent inventors’ decisions to patent and commercialize inventions. Using data from 559 inventions and controlling for demand, appropriability, and competitive conditions, we found two of four tested dimensions of technological opportunity - technical performance and technical uncertainty - to be significant and important determinants of the likelihood of commercialization. Technical feasibility appears important in affecting patenting but unimportant in affecting commercialization. Technical significance carries a negative, although insignificant, sign conditioning commercialization.  相似文献   

Factors affecting journal submission numbers: Impact factor and peer review reputation     

Thomas E. Gaston  Francesca Ounsworth  Tessa Senders  Sarah Ritchie  Emma Jones 《Learned Publishing》2020,33(2):154-162

Previous research has found that researchers rank journal reputation and impact factor (IF) amongst the key selection criteria when choosing where to submit. We explored the actual effect upon submission numbers of several possible factors. We retrieved 10 years of submission data from over a thousand journals, as well as data on IF, retractions, and other factors. We performed statistical analysis and identified correlations. We also undertook case study research on the 55 most significant submission decreases. We found a statistically significant correlation between changes in IF, ISI percentage ranking, and changes in submissions numbers in subsequent years. We also found a statistically significant effect on submission numbers in the year following the publication of a retraction. Our case studies identified other factors, including negative feedback on the peer review process. Our findings regarding IF confirm previous indications about the significance of IF on submissions. We explain the correlation with retractions through the concept of ‘peer review reputation’. These results indicate that editors and publishers need to focus on a journal's peer review practices, as well as a journal's IF, if they are to maintain and grow submissions.  相似文献   

The lamaze certified childbirth educator: standards of practice     

Lothian JA 《The Journal of perinatal education》2007,16(1):29-31

A student in a Lamaze Childbirth Educator Program expresses concern that some Lamaze Certified Childbirth Educators (LCCE educators) do not teach classes that reflect Lamaze standards. In this column, the ethical and professional standards of the LCCE educator and the challenges the childbirth educator experiences while practicing in the current maternity-care environment are presented and discussed. Lamaze International's Code of Ethics for Lamaze Certified Childbirth Educators provides guidance when dealing with these challenges.  相似文献   

Screening of phonological awareness in the early elementary grades: an IRT approach     

Vloedgraven JM  Verhoeven L 《Annals of dyslexia》2007,57(1):33-50

The purpose of the present study was to explore the possibilities for the assessment of growth in phonological awareness of children in kindergarten and first grade. Phonological awareness was measured using four sets of items involving rhyming, phoneme identification, phoneme blending, and phoneme segmentation. The results of an exploratory factor analysis and analyses conducted within the framework of item response theory showed one latent ability to underlie the different sets of items, which nevertheless differed in difficulty. Analyses in terms of the children’s ability further showed the phonological awareness measures to be sensitive to growth. The amount of information supplied by the different sets of items depended on the children’s level of ability. The conclusion that it is possible to accurately monitor the development of children’s phonological awareness in the early elementary grades appears to be justified, and this possibility opens up new perspectives for the early screening for reading problems and dyslexia.  相似文献   

Time for inclusion?     

Matthew Krehl Edward Thomas  Benjamin Jay Whitburn 《British Journal of Sociology of Education》2019,40(2):159-173

This article examines the constraints of modern temporality which are antithetical to the careful consideration that working with diverse learners requires for the development of inclusive, democratic education. We take up the conceptual construct of time to explore how it mediates systemic practices that impact policy positions of inclusion in initial teacher education and schooling. Our analysis demonstrates that temporality shapes the possibilities of inclusive practice within which a dominant agenda of compliance frames classroom complexities – both in schooling and higher education environments – into fragmented and preconceived responses to challenging situations. Education systems position educators in risk discourses concentrated on compliance and performance, in part through an emphasis that is placed on the diagnosis of learner differences and subsequent compartmentalised responses. Through schisms in modern time, we demonstrate the ways in which inclusion, like other educational demands, may be supported through a diffraction in time rather than subjugated to it.  相似文献

A Multipart Project Planning and Tracking Exercise     

Thomas R. Robbins 《Decision Sciences Journal of Innovative Education》2019,17(2):104-125

Project Management is an important skill for business students to develop. Although project‐oriented activity is very common, the success rate for projects is poor. Many projects fail due to poor planning. This article describes a multipart class exercise used to teach elements of a project management methodology to undergraduate and graduate business students. Over the course of the eight‐part exercise, student teams iteratively develop a project plan and Gantt chart, an initial and detailed project charter, a variance analysis model, and a status report. Students are taught an iterative top‐down planning process using a technique we term the ODW (Objectives–Deliverables–Workplan) model. Students are introduced to Microsoft Project and use the tool to develop a project plan that becomes part of a more detailed Project Charter. In the final stages of the exercise, students collect results, update their plan, and produce a project status report.  相似文献
