Given the large uncertainties regarding potential damages from climate change and the significant but also uncertain costs of reducing greenhouse emissions, the debate over a policy response is often framed as a choice of either acting now or waiting until the uncertainty is reduced. Implicit behind the “wait to learn” argument is the notion that the ability to learn in the future necessarily i...

the aim of this research was to measure the relative efficiency of forest management plans in north of iran. in order to fulfill the research, data of 12 forest management plans were collected from the financial balance sheets of shafaroud forest company during a ten years period. first of all, basic data envelopment analysis (dea) models (bcc and ccr) were used to determine the efficiency. the...

Global warming due to greenhouse effect is expected to cause major changes in climate of some regions. The change of climate is likely to have a profound effect on hydrological cycle. Evapotranspiration (ET, as the major component of hydrological cycle, will affect crop water requirement and future planning and management of water resources. This study was conducted to investigate climate chang...

Abstract. We present a Bayesian analysis for recurrent events data using a nonhomogeneous mixed Poisson point process with a dynamic subject-specific frailty function and a dynamic baseline intensity func- tion. The dynamic subject-specific frailty employs a dynamic piecewise constant function with a known pre-specified grid and the baseline in- tensity uses an unknown grid for the piecewise ...

This paper will focus on the topic of organisational change and its management from an information systems perspective. The paper will examine the issues raised during a review of the change management literature – looking at the major approaches to change management, namely, the planned, emergent and contingency approaches – as background to the issues raised in other papers in this theme of t...

Product data management is an engineering oriented information system. Engineering change request, engineering change notice, and engineering change control workflow in a product data management system are usually utilized starting from the detail product design phase. Lack of guidelines to identify configuration items and design change control workflow is one of the major reasons for not using...

one of the ways to manage human resources is performance management. with a systematic approach, this sort of management determines strategic goals, identifies indexes, collects, analyzes and reports data and ultimately improves the organization performance. performance management is a process that calls for the interaction of factors such as administrative goals, accountability standards and e...
