The Effects of Human Resource Management Practices on Productivity [PDF]

open access: yes
Increasingly, firms are considering the adoption of new work practices, such as problem-solving teams, enhanced communication with workers, employment security, flexibility in job assignments, training workers for multiple jobs, and greater reliance on ...

Assessing Site Productivity of Indigenous Cypress Pine Forest in Southern Queensland [PDF]

open access: yes, 1988
Site form, the expected height of a 25 cm d.b.h.o.b. tree predicted from the stand height-diameter relationship, is shown to be a practical and useful measure of site productivity in indigenous cypress pine (Callitris sp.) forests in southern Queensland.

An extended Cretaceous-Tertiary (K/T) stable isotope record. Implications for paleoclimate and the nature of the K/T boundary event [PDF]

open access: yes
In order to obtain a detailed single site record of marine productivity and temperature across the Cretaceous-Tertiary (K/T) boundary, both delta C-13 and delta O-18 values were measured in paired surface and deep water microfossil and nannofossil ...

Study of relationship between time overrun and productivity on construction sites [PDF]

open access: yesInternational Journal of Construction Supply Chain Management, 2011
The history of the construction industry worldwide is full of projects that were completed with significant time and cost overruns. In an attempt to reverse this trend, this study aims at establishing the relationship between time overrun and labour ...

Latitudinal effects on crown shape evolution

open access: yesEcology and Evolution, 2018
Large variations in crown shape are observed across the globe, from plants with wide and deep crowns to those with leaves clustered at the top. While there have been advances in the large‐scale monitoring of forests, little is known about factors driving

Optimal Forest Taxation under Private and Social Amenity Valuation [PDF]

open access: yes
This paper analyzes socially optimal forest taxation when the government has a binding tax revenue requirement. In the Faustmann model the optimal design of forest taxation consists of non-distortionary taxes, such as site productivity tax, site value ...

How do stand age and site quality shape productivity of Chinese fir plantations via stand structural pathways?

open access: yesFrontiers in Plant Science
Stand productivity in plantation forests arises from the interaction among developmental stage, site potential, and structural organization, yet the pathways through which stand age and site quality regulate productivity remain insufficiently clarified ...

Response of temperate grasslands at different altitudes to simulated summer drought differed but scaled with annual precipitation [PDF]

open access: yesBiogeosciences, 2009
Water is an important resource for plant life. Since climate scenarios for Switzerland predict an average reduction of 20% in summer precipitation until 2070, understanding ecosystem responses to water shortage, e.g. in terms of plant productivity, is of

Expanding alternate wetting and drying and improving its productivity in irrigated rice: Identification of required plant traits and suitable soil types [PDF]

open access: yes, 2010
Irrigated rice consumes two to three times more water than other cereals. The availability of water is, however, decreasing and this prompted researchers to find ways in saving water in irrigated rice fields where high yield is critical to ensure food ...
