Analysis of Trade and Employment in Manufacturing Industry Using Panel Data Method

The increasing importance of unemployment in the world economies has led to investigation of impact of foreign trade on employment. In this respect there are several studies concerning employment impact of foreign trade. In this study, employment impact of foreign trade is estimated with panel data analysis using annual data of 22 manufacturing industries of Turkish economy according to two digit level of NACE Rev. 1.1 classification for the period of 2003-2008. Since the dataset has both cross-sectional and time series elements, fixed effects estimators and random effects estimators were used for the estimation of models. Results of this study show that while production has positive and wages have negative and significant impact on employment, foreign trade has no significant impact on employment for the period of analyzed. This implies that impact of wages and production on employment consistent with economic theory and the measures of foreign trade policies to improve employment are insufficient in the period of analyzed.Exports; Imports; Employment; Panel data analysis; manufacturing industry

Relationship of hemoxygenase-1 and prolidase enzyme activity with oxidative stress in papillary thyroid cancer

Aim: Recent studies associate thyroid cancer with oxidative stress. We aim to clarify the relation between papillary thyroid cancer, oxidative stress, hemoxygenase-1, prolidase enzymes and investigate the availability of these enzymes as markers for diagnosis, success of treatment, and follow-up. Methods: Thirty-one patients with papillary thyroid carcinoma and 25 healthy control subjects were included in this study. Hemoxygenase-1, prolidase (oxidant stress indicator), malondialdehyde, protein carbonyl, and superoxide dismutase (an indicator of antioxidant defense system) were measured pre-operatively and 30 days after thyroidectomy. Results: There was a significant decrease in serum levels of malondialdehyde and superoxide dismutase (p <0.001 for both) after thyroidectomy in papillary thyroid carcinoma group. In addition, there was a significant difference in the postoperative serum levels of prolidase, malondialdehyde, protein carbonyl, and superoxide dismutase between papillary thyroid carcinoma and control groups (p =0.024, p <0.001, p =0.002, and p =0.016, respectively) beside significant difference of malondialdehyde, protein carbonyl, hemoxygenase-1, and superoxide dismutase pre-operative serum levels (p <0.001, p =0.003, p =0.006, and p =0.025, respectively). Conclusion: When the unquestionable role of oxidative stress in the pathogenesis of cancer is considered, in the future it is expected to associate parametric changes in the serum of patients caused by oxidative stress to papillary thyroid cancer.
