Labor-force Participation of Married Women in Turkey: A Study of the Added-Worker Effect and the Discouraged-Worker Effect

Cataloged from PDF version of article.We analyze married women's labor-supply responses to their husbands' job loss (added-worker effect) and worsening of unemployment conditions (discouraged-worker effect). We construct six two-year pseudopanels based on the previous year's labor market outcomes using nationally representative Turkish Household Labor Force Surveys from 2005 to 2010. We find that women whose husbands involuntarily transition from employment to unemployment are more likely to participate in the labor force. We pool the six-year pseudopanels and examine the effects of aggregate employment conditions on wives' transition to the labor force. A worsening of unemployment conditions has a small discouraging effect on wives' labor-supply responses

An evaluation of three DoE-guided meta-heuristic-based solution methods for a three-echelon sustainable distribution network

This article evaluates the efficiency of three meta-heuristic optimiser (viz. MOGA-II, MOPSO and NSGA-II)-based solution methods for designing a sustainable three-echelon distribution network. The distribution network employs a bi-objective location-routing model. Due to the mathematically NP-hard nature of the model a multi-disciplinary optimisation commercial platform, modeFRONTIER®, is adopted to utilise the solution methods. The proposed Design of Experiment (DoE)-guided solution methods are of two phased that solve the NP-hard model to attain minimal total costs and total CO2 emission from transportation. Convergence of the optimisers are tested and compared. Ranking of the realistic results are examined using Pareto frontiers and the Technique for Order Preference by Similarity to Ideal Solution approach, followed by determination of the optimal transportation routes. A case of an Irish dairy processing industry’s three-echelon logistics network is considered to validate the solution methods. The results obtained through the proposed methods provide information on open/closed distribution centres (DCs), vehicle routing patterns connecting plants to DCs, open DCs to retailers and retailers to retailers, and number of trucks required in each route to transport the products. It is found that the DoE-guided NSGA-II optimiser based solution is more efficient when compared with the DoE-guided MOGA-II and MOPSO optimiser based solution methods in solving the bi-objective NP-hard three-echelon sustainable model. This efficient solution method enable managers to structure the physical distribution network on the demand side of a logistics network, minimising total cost and total CO2 emission from transportation while satisfying all operational constraints

Identification of recent tuberculosis exposure using QuantiFERON-TB Gold Plus, a multicenter study.

We investigated whether the difference of antigen tube 2 (TB2) minus antigen tube 1 (TB1) (TB22TB1) of the QuantiFERON-TB gold plus test, which has been postulated as a surrogate for the CD81 T-cell response, could be useful in identifying recent tuberculosis (TB) exposure. We looked at the interferon gamma (IFN-g) responses and differences in TB2 and TB1 tubes for 686 adults with QFT-plus positive test results. These results were compared among groups with high (368 TB contacts), low (229 patients with immune-mediated inflammatory diseases [IMID]), and indeterminate (89 asylum seekers or people from abroad [ASPFA]) risks of recent TB exposure. A TB22TB1 value .0.6 IU ml21 was deemed to indicate a true difference between tubes. In the whole cohort, 13.6%, 10.9%, and 11.2% of cases had a TB2.TB1 result in the contact, IMID, and ASPFA groups, respectively (P = 0.591). The adjusted odds ratios (aORs) for an association between a TB22TB1 result of .0.6 IU ml21 and risk of recent exposure versus contacts were 0.71 (95% confidence interval [CI], 0.31 to 1.61) for the IMID group and 0.86 (95% CI, 0.49 to 1.52) for the ASPFA group. In TB contact subgroups, 11.4%, 5.4%, and 17.7% with close, frequent, and sporadic contact had a TB2.TB1 result (P = 0.362). The aORs versus the close subgroup were 1.29 (95% CI, 0.63 to 2.62) for the frequent subgroup and 1.55 (95% CI, 0.67 to 3.60) for the sporadic subgroup. A TB22TB1 difference of .0.6 IU ml21 was not associated with increased risk of recent TB exposure, which puts into question the clinical potential as a proxy marker for recently acquired TB infection

Dislocating anterior horn of the medial meniscus.

Dislocating anterior horn of the medial meniscus was found in 15 knees of 13 patients during arthroscopic examinations done between 1992 and 1995. All of them were available for follow-up evaluation (4 by telephone). There were 11 men and 2 women (average age, 28 years; range, 17 to 49 years). Nine knees had a history of trauma. Only 1 knee had had trauma in two bilateral cases. Duration of symptoms was an average of 3.3 years (range, 3 months to 10 years). The knees were stable clinically. Arthroscopy revealed associated lesions in 13 knees; hypertrophic medial plicae, meniscal, chondral and anterior cruciate ligament (ACL) lesions predominated. Three knees had unusually hypertrophic ligamentum mucosum. Eleven of 13 knees had more than one associated lesions. Only 2 knees (2 patients) had isolated dislocating anterior horn of the medial meniscus. Only the associated lesions were treated (except for ACL lesions) and dislocating anterior horns of the medial menisci were left alone. Follow-up averaged 21 months (7 to 40 months). At follow-up, 11 knees were graded as excellent, 3 as good, and 1 as fair according to the Lysholm scale. Eight knees had minor symptoms and 6 were asymptomatic; no improvement was noted in 1 knee. Overall, 12 patients (14 knees) were satisfied with their treatment. Dislocating anterior horn of the medial meniscus is a normal anatomic variant with little or no clinical significance. When seen during arthroscopy, a significant lesion should be looked for. It is an incidental finding and should be left alone

Patellofemoral joint dynamics in patients with gonarthrosis

Objectives: Although the tibiofemoral joint has been evaluated in most of the gonarthrosis studies, the relationships between gonarthrosis and the patellofemoral joint have usually been disregarded. In this study, the dynamics of the patellofemoral joint in gonarthrosis has been evaluated. Patients and methods: Dynamic and kinematic axial computed tomography scans were obtained in 33 knees of 22 patients (19 females, 3 males; mean age 67.0 +/- 3.2; range 58 to 75 years) who were scheduled for total knee arthroplasty due to the gonarthrosis. The control group consisted of 28 knees of 14 normal volunteers (11 females, 3 males, mean age 25 +/- 4.6; range 10 to 46 years) without any knee complaints or disorders. Sulcus, congruence and patellar tilt angles were measured on axial images which were obtained in different flexion angles of the knee (0 degrees, 10 degrees, 20 degrees, 30 degrees, 40 degrees and 60 degrees), both with and without contraction of the quadriceps muscle. ANOVA and paired-t tests were used for statistical analysis. Results: Patellar tilt increased significantly in gonarthrotic patients compared to the controls (p<0.05). The congruence angle was significantly lower in patients at 0 degrees and 10 degrees of knee flexion, but higher at 20 degrees, 30 degrees, 40 degrees and 60 degrees than controls (p<0.05). The congruence angle increased significantly with the contraction of the quadriceps in controls, but no significant changes were observed in patients. Conclusion: Dynamics of the patellofemoral joint is different in patients with gonarthrosis than normal volunteers. Patellofemoral complaints following knee arthroplasties may be related to these differences
