Growing Problem Solvers provides four original, related, classroom-ready mathematical tasks, one for each grade band. Together, these tasks illustrate the trajectory of learners’ growth as problem solvers across their years school mathematics.

Fringe benefits compensation offered by employers has grown rapidly over the past 50 years. Research in this area has been primarily limited to hourly and salaried employees. This study examines employer-based fringe benefits compensation of real estate agents and brokers. A model is developed that jointly estimates the income, hours worked, and fringe benefits compensation. The findings indica...

While a stated goal of minimum wage increases is to benefit low-income workers, some employers are not obligated to provide at least minimum wages to all employees. U.S. farm employers comprise one of these groups. Employees of large farms and H2-A workers (temporary nonimmigrant workers lawfully admitted to perform temporary or seasonal agricultural services) are protected by minimum wage legi...

BACKGROUND Although burnout is viewed as a syndrome rooted in the working environment and organizational culture, the role of the learning environment in the development of resident burnout remains unclear. We aimed to evaluate the association between burnout and the learning environment in a cohort of Belgian residents. METHODS We conducted a cross-sectional online survey among residents in ...

The discussion about the long-run evolution of labor productivity in Switzerland is awed because the available data on the input of labor is incoherent and incomplete. It is the aim of this paper to establish a consistent aggregate series of total hours worked covering 195

OBJECTIVES This study describes the toxicokinetics, pulmonary function, and subjective ratings of discomfort in volunteers experimentally exposed to turpentine vapour (a mixture of monoterpenes). The results were compared with similar exposure to single monoterpenes to look in the toxicokinetics and acute effects for signs of interactions between the monoterpenes. METHODS Eight male volunteer...

modeling and analysis of future prices has been hot topic for economic analysts in recent years. traditionally, the complex movements in the prices are usually taken as random or stochastic process. however, they may be produced by a deterministic nonlinear process. accuracy and efficiency of economic models in the short period forecasting is strategic and crucial for business world. nonlinear ...

Human exposure to mechanical vibration may represent a significant risk factor for exposed workers in the agricultural sector. Also, noise in agriculture is one of the risk factors to be taken into account in the evaluation of workers' health and safety. One of the major sources of discomfort for the workers operating a tractors is the noise to which they are exposed during work. The aim of thi...

Economic debates over minimum wage policy are typically premised on the assumption that raising a binding wage floor must reduce long-run employment if the affected markets are competitive and complete. It is shown here to the contrary that employment effects of raising the minimum are indeterminate if competitive employers incur person-specific labor costs, which vary with the number of employ...

The release of Enovid in 1960, the first birth control pill, afforded U. S. women unprecedented freedom to plan childbearing and their careers. This paper uses plausibly exogenous variation in state consent laws to evaluate the causal impact of the pill on the timing of first births and extent and intensity of women’s labor-force participation. The results suggest that legal access to the pill ...
