The influence of grandparents’ social class on children’s aspirations     

Vanessa Moulton  Eirini Flouri  Heather Joshi  Alice Sullivan 《British Journal of Sociology of Education》2017,38(4):500-517

Social class mobility from grandparent to grandchild is a relatively neglected topic. Grandparents today are often healthier and more active, and have longer relationships with their grandchildren than in previous generations. We used data from the UK’s Millennium Cohort Study (n = 8570) to investigate the influence of maternal and paternal grandparents’ social class on the aspirations of children at age seven. Using path analysis and controlling for family income, mother’s and father’s education, lone motherhood, and child’s ethnicity and gender, we found very small direct effects from the paternal grandmother’s social class to the grandchild’s classed aspirations, and small, indirect effects, via parents’ class, of grandparents’ class on child’s classed aspirations. Multi-group analyses found few differences by ethnicity and gender. There was no evidence that, at this age, mixed-class parentage raises the aspirations of working-class children (the ‘sunken middle-class’ hypothesis).  相似文献   

Diurnal variation in serum glucose,pyruvate, lactate and lactate dehydrogenase levels under different environmental temperatures     

S. K. Bansal  H. N. Pandey  A. Bansal  L. D. Joshi 《Indian journal of clinical biochemistry : IJCB》1992,7(2):179-184

Circadian rhythm of serum glucose, pyruvate, lactate and lactate dehydrogenase (LDH) was studied in normal healthy young volunteers at the onset (I Group, 7 cases) and peak (II Group, 8 cases) of winters in India with highly varied temperature. There was a significant difference, in the circadian rhythm of glucose, pyruvate and lactate dehydrogenase (LDH) of the two groups. A clockwise shift was observed in acrophase except in serum lactate, which is related to the energy demand in association with time qualified changes in diurnal activity of the individuals and change in photoperiod.  相似文献   

Some biochemical markers in various neoplasms: A multivariate analysis     

Bhawana Nigam  S. P. Joshi  Seema Nagar  Rajesh Chavan  D. Pendharkar 《Indian journal of clinical biochemistry : IJCB》1996,11(2):124-128

The analysis of biochemical parameters in 162 patients with various neoplastic disorders along with 50 normal subjects showed significant rise in serum alkaline phosphatase and lactate dehydrogenase as compared to normal subjects. 21 patients with other monoclonal gammopathies which include infection and immunological diseases were also studied. Parameters such as serum calcium, uric acid, total protein, albumin and globulin were also analyzed in 42 (26%) cases of multiple myeloma, 27 (17%) cases of gastro-intestinal malignancies, 22 (14%) cases of urogenital malignancies, 11 (6%) cases of carcinoma breast, 4 (2%) cases of bone tumors, 21 (12%) cases of other monoclonal gammopathies, including 7 (4%) cases of infection and 14 (8%) cases of immunological diseases. The results indicate use of enzymes alkaline phosphatase and lactate dehydrogenase in neoplastic disorders.  相似文献   

Study of adenosine deaminase activity in various arthritic conditions     

R. Kumar  S. B. Pachori  G. K. Senger  Satyanand  L. D. Joshi 《Indian journal of clinical biochemistry : IJCB》1994,9(2):72-74

Aim of present study was to compare the adenosine deaminase (ADA) activity in various types of arthritis conditions with synovial effusion. No. significant difference was observed in ADA activity in serum of control and study groups but results have shown a definite pattern of ADA activity in synovial fluid in various arthritic conditions. The highest value of ADA activity was observed in synovial fluid of patients with tubercular arthritis followed by rheumatoid, septic, osteo and post traumatic arthritis. Thus measurement of ADA activity in synovial fluid can be used as a parameter of differential diagnosis of arthritis specially tubercular in initial stages.  相似文献   

Are preservice teachers prepared to teach struggling readers?   总被引：1，自引：0，他引：1  

Erin K. Washburn  R. Malatesha Joshi  Emily Binks Cantrell 《Annals of dyslexia》2011,61(1):21-43

Reading disabilities such as dyslexia, a specific learning disability that affects an individual’s ability to process written language, are estimated to affect 15–20% of the general population. Consequently, elementary school teachers encounter students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language processing difficulties. However, recent evidence may suggest that teacher preparation programs are not providing preservice teachers with information about basic language constructs and other components related to scientifically based reading instruction. As a consequence preservice teachers have not exhibited explicit knowledge of such concepts in previous studies. Few studies have sought to assess preservice teachers’ knowledge about dyslexia in conjunction with knowledge of basic language concepts. The purpose of the present study was to examine elementary school preservice teachers’ knowledge of basic language constructs and their perceptions and knowledge about dyslexia. Findings from the present study suggest that preservice teachers, on average, are able to display implicit skills related to certain basic language constructs (i.e., syllable counting), but fail to demonstrate explicit knowledge of others (i.e., phonics principles). Also, preservice teachers seem to hold the common misconception that dyslexia is a visual perception deficit rather than a problem with phonological processing. Implications for future research as well as teacher preparation are discussed.  相似文献   

Two-dimensional collision –at higher secondary level     

A. W. Joshi  Vijayshri 《Resonance》2006,11(3):69-79

The treatment of two-dimensional collision of bodies in textbooks at various levels was examined. It is found that while many books do not mention impact parameter at all, some books show it in a diagram, though they do not include it in the mathematical treatment that follows. In this article, the importance of impact parameter is highlighted and a simple treatment which does not go beyond the higher secondary level is developed. A simple experiment is suggested.  相似文献   

Oxidative Stress-Induced Response of Some Endogenous Antioxidants in Schizophrenia     

Gora Dadheech  Praveen Sharma  Shiv Gautam 《Indian journal of clinical biochemistry : IJCB》2012,27(3):278-283

Reactive oxygen species (ROS) formed in various metabolic reactions cause unlimited damage by attacking and oxidizing the macromolecules. An arsenal of antioxidant substances neutralizes these ROS at various sites of their metabolic cascade, and if disequilibrium exists between the pro and antioxidant system, oxidative stress persists. The present study was undertaken in schizophrenia, to highlight the response and role of some endogenous antioxidants viz. reduced glutathione (GSH), bilirubin, total proteins, albumin and uric acid in scavenging the ROS. The effect of severity of disease, age factor, and substance abuse was also studied. In all, 50 schizophrenics and 50 age and sex-matched controls were enrolled in the present study. Fasting blood samples were drawn for estimating malondialdehyde (MDA), GSH, bilirubin, total proteins, albumin and uric acid in both the groups. The results were statistically analyzed by Z-test and correlated using correlation coefficient (r). The study shows reduction in MDA levels and decline in the level of endogenous antioxidants, but within the normal range. Chronic schizophrenics were at a higher risk of oxidative stress and age and substance abuse seems to worsen the situation.  相似文献   

Mentoring partnerships in a community technology centre: A constructionist approach for fostering equitable service learning     

Yasmin B. Kafai  Shiv Desai  Kylie A. Peppler  Grace M. Chiu  Jesse Moya 《Mentoring & Tutoring: Partnership in Learning》2013,21(2):191-205

Mentoring programmes have gained increasing popularity in institutions of higher education to support undergraduates in community service or outreach efforts. Many of these programmes partner mentors with inner‐city youth, providing assistance in underserved communities while mentors gain experiences that connect theory and practice. Here we report on two years of fieldwork in a Community Technology Centre that created mentoring partnerships in which 36 liberal arts undergraduates engaged with local youth to design, create, and build technology projects involving graphics, video, music, and animation. We analysed over 200 field notes, which described their mentoring interactions over eight weeks and conducted exit interviews about their mentoring experiences. Our results indicate that mentors participated not just as more knowledgeable peers but also as facilitators, advisors, observers and, most importantly, as learners in this process. In the interviews, nearly all mentors reviewed assumptions about their own learning and mentoring, in addition to reflections about social issues. We discuss the importance of these findings for conceptualising mentoring as a partnership by creating more equitable interactions in service learning initiatives. We also address the role of constructionist activities in facilitating learning opportunities for both mentors and mentees.  相似文献   

Changes in serum lipids in normal and diabetic guinea pigs on feeding Phaseolus aureus (Green gram)     

Anurag Srivastava  L. D. Joshi  S. P. Singh 《Indian journal of clinical biochemistry : IJCB》1989,4(1):50-57

Normal and alloxan induced diabetic guinea pigs were kept on whole seed diet of green gram for 4 weeks. Serum total lipids were found to be significantly decreased in both normal and diabetic guinea pigs (P <0.001)—Both free and esterified fractions of cholesterol were found to be lowered significantly in diabetic animals (P<0.05; <0.01, respectively), whereas only esterified fraction was reduced significantly in case of normals (P<0.05). Significant lowering of triglyceride levels (P<0.01) was also noticed in both normal as well as diabetic guinea pigs while phospholipids remained almost unaffected. Green gram feeding decreased the total cholesterol / phospholipid ratio from 0.630 to 0.625 in normal and from 1.039 to 0.850 in diabetic guinea pigs indicating its antiatherogenic nature.  相似文献
