Fetal primary small bowel volvulus is extremely rare but represents a serious life-threatening condition needing emergency neonatal surgical management to avoid severe digestive consequences. We report a case of primary small bowel volvulus with meconium peritonitis prenatally diagnosed at 27 weeks and 4 days of gestation during threatened premature labor with reduced fetal movements. Ultrasoun...

The principal focus of this study is on the measurement and analysis of labor learnings in Pakistan. The study at the aggregate economy level focus on the labor productivity movements and at large-scale manufacturing level focus on the cost structure, with isolating the contribution of the learning curve. The analysis of S-shaped curve suggests that learnings are only below one half of aggregat...

Democracies depend on countervailing power. Opposition to authoritarian regimes requires large-scale counter-mobilization. Labor organization—be it in the form of unions or social movements—is often key to both. But by most measures labor power is decreasing just when corporate power appears to be increasing. Union membership, electoral and lobbying pressure, and protest, the indicators we gene...

In this paper, we compare the effects of machine pooling and labor chaining by means of a simulation study. In this study, the independent variables are: (1) the level of machine pooling (no. of jobs that can be produced in more than one cell), (2) the level of labor chaining (no. of workers able to work in more than one cell), and (3) labor utilization/machine utilization. The dependent variab...

We examine the sources of aggregate labor productivity movements and convergence in the U.S. states from 1963 to 1989. Productivity levels vary widely across sectors and across states, as do sectoral output and employment shares. The main finding is the diverse performance of sectors regarding convergence. Using both cross-section and time series methods, we find convergence in labor productivi...
