Journal of Adolescence, EarlyView.ABSTRACT Introduction The cultural normativeness hypothesis suggests that helicopter parenting might be less problematic in Chinese cultures, which strongly value intensive parental involvement. Chinese helicopter parenting might show positive associations with both problematic (i.e., conflict) and beneficial (i.e., support) aspects of youth‐parent ...

Informing DSGE Models Through Dynamic Factor Models
Journal of Applied Econometrics, EarlyView.ABSTRACT Structural dynamic factor models (SDFM) represent a reliable tool to inform the construction of dynamic stochastic general equilibrium (DSGE) models. The reason is that the log‐linear solution of a DSGE model has a factor structure which ensures consistency between the representations of the two models.

Journal of Environmental Quality, EarlyView.Abstract Closed depressions in post‐glacial landscapes can accumulate phosphorus (P) due to repeated flooding and become hotspots for P loss when underlain by subsurface (tile) drainage. Soil P mapping is routinely based on the interpolation of samples from a 1‐ha grid, which may miss closed depressions and underestimate soil P levels leading to ...

A Nordhaus–Gaddum Problem for the Spectral Gap of a Graph
Journal of Graph Theory, EarlyView.ABSTRACT Let G $G$ be a graph on n $n$ vertices, with complement G¯ $\bar{G}$. The spectral gap of the transition probability matrix of a random walk on G $G$ is used to estimate how fast the random walk becomes stationary. We prove that the larger spectral gap of G $G$ and G¯ $\bar{G}$ is Ω(1∕n) ${\rm{\Omega }}(1\unicode{x02215}n)$.

Evolutions of Omni‐Channel Fulfillment Performance: An In‐Depth Case Study in Grocery Retailing
Journal of Operations Management, EarlyView.ABSTRACT The rapid adoption of omni‐channel strategies has prompted grocery retailers to reconfigure their back‐end fulfillment operations to efficiently and effectively meet the demands of online and offline retail channels. Viewing back‐end fulfillment operations in omni‐channel grocery retail as a complex adaptive system, we present an eight‐year ...

Is volume index of gdp per capita stationary in oecd countries? panel stationary tests with structural breaks [PDF]
The purpose of this paper is to investigate whether volume index of GDP per capita is stationary for 24 OECD countries during the period 1970 to 2006. We utilize a panel stationary tests that allow for multiple structural breaks, developed by Carrion-i ...
