Trade Liberalization and Labor-Demand Elasticities: Empirical Evidence from Tunisia This paper investigates the effects of trade liberalization on labor demand elasticities. Employment demand equation is estimated by using data (1971-1996) for manufacturing industries in Tunisia. Results from empirical testing using the model find a weak support for the(More)
In this paper we analyze the trends in youth employment and unemployment in Tunisia from 1984 to 2010. Next we evaluate the labor market reforms and active labor market policies undertaken by the Tunisian government in order to assess the effectiveness of these policies. We have three main findings. First, while unemployment is primarily a youth phenomenon(More)
This paper investigates short and long-run effects of trade liberalization on employment and wages. Employment and wage equations are estimated using data (1971–96) for importable and exportable sectors in Tunisia. Causality tests show that causality is unidirectional. Wages strongly causes employment but employment does not cause wages. There is(More)
AIM To study the influence of cryoprotectant, cooling rate, and warming rate on recovery and viability of keratocytes from corneas for cryolathing. METHODS Corneas were frozen at -50 degrees C for 2 minutes either after exposure to 10% dimethyl sulphoxide in Eagle's MEM for 15 minutes at room temperature (about 22 degrees C), or without earlier exposure(More)
Rabbit corneas were perfused in vitro with an irrigation solution for 90 minutes. This was followed by 6 hours of perfusion with tissue culture medium TC199 during which endothelial function was assessed by monitoring rates of swelling during a period of perfusion in the absence of bicarbonate ions, and subsequent rates of thinning when bicarbonate ions(More)
OBJECTIVE To establish the feasibility and safety of recuperating blood absorbed by swabs used during orthopaedic surgery. STUDY DESIGN Open, prospective study. PATIENTS Included were children undergoing potentially haemorrhagic orthopaedic surgery for whom intraoperative blood salvage seemed possible. Excluded were those with contraindications for this(More)
