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

Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction.  相似文献

The authors examined the associations between observed classroom management and teacher-child relationships with individual children during kindergarten and Grade 1. We used a sample of nonstruggling and struggling readers and their teachers in rural schools in the Southeastern United States to examine whether gender and struggling reader status explained associations between classroom management and conflictual or close teacher-child relationships. After controlling for child- and teacher-level characteristics, results from multilevel model analyses indicated that stronger classroom management was significantly related to less teacher-rated conflict, but was not related to teacher-rated closeness. Gender was a significant moderator, with boys who were in classrooms with lower levels of classroom management having poorer teacher-child relationships as rated by their teachers. Struggling reader status was not a significant moderator of the association between classroom management and teacher-child relationships.  相似文献

Many mathematics teachers opt for a strictly teacher‐centred curriculum and/or instructional strategy. Given the well‐documented evidence noting the benefits of student‐centred instruction, it is easy to see that teacher‐centred learning on its own cannot best meet the needs of students. On the other hand, some teachers, aware of the importance of a student‐centred mathematics curriculum, adopt an exclusively student‐centred approach to curriculum and instruction. What is less obvious is that this approach can put some students who belong to certain ethnic groups at a disadvantage. Hence, to be more inclusive, mathematics educators need to take a balanced instructional approach. This paper outlines an inclusive instructional strategy that resembles the structure of and exemplifies the values promoted by the Aboriginal model of the Medicine Wheel.  相似文献

In the present study the efficacies of therapy with insulin, sulphonylurea or insulin + metformin on NIDDM patients are compared. One group which was on a definite dose of insulin therapy, but with uncontrolled diabetes was treated by doubling the insulin dose, a second group whose diabetes was not controlled by glibenclamide was switched over to another sulphonylurea viz; glimepiride and a third group whose diabetes was not controlled by insulin therapy was switched over to a combination therapy with insulin +metformin. After recording their initial blood parameters all the groups were treated as above for 3 months, and the parameters were again determined. The fasting blood sugar and serum lipids of the first group were controlled significantly, but the values were far above normal range. However HDL Cholesterol and atherogenic index were near normal range. In glimepiride treated group, none of the parameters showed any amelioration. In the combined therapy group, control of blood sugar and atherogenic index was more or less the same as for group 1, but hyperlipidemia remained slightly above that of the same. From the findings we can infer that in long term diabetes treatment higher doses of insulin and combined therapy with insulin and metformin may be more beneficial than with low doses of insulin or sulfonyl urea alone  相似文献

Decentralisation of educational planning continues to be a major concern in India. The District Primary Education Programme (DPEP) is one of the recent efforts in this direction. This paper closely scrutinises various steps initiated under the DPEP to promote decentralisation of educational planning in India. The analysis in this paper shows that the DPEP initiatives have succeeded in overcoming existing constraints on decentralisation by developing planning machinery and competency and by ensuring resource availability at the district level. The DPEP experience also shows that centralised decision making in certain areas in the initial stages may become necessary to promote decentralisation efforts in the long-run. However, to sustain the decentralisation process, it is important to progressively reduce the domains of centralised decision making.  相似文献

Three experiments investigated 3‐, 4‐, and 5‐year‐olds' (= 240) understanding that their future or “grown‐up” preferences may differ from their current ones (self‐future condition). This understanding was compared to children's understanding of the preferences of a grown‐up (adult‐now condition) or the grown‐up preferences of a same‐aged peer (peer‐future condition). Children's performance across all three conditions improved significantly with age. Moreover, children found it significantly more difficult to reason about their own future preferences than they did to reason either about an adult's preferences or the future preferences of a peer. These results have important implications for theories about future thinking and perspective‐taking abilities, more broadly.  相似文献
