Portfolio management is widely used by large government agencies and nonprofits, but it rarely discussed in public administration scholarship. tools can illuminate groups of projects that should be considered as priority investments highlighting the relationship risk to outcomes. This article explores historical theoretical reasons for neglect portfolio management, then proposes using update a ...

Pileups of screw dislocations against an inclined bimetallic interface are considered. It is assumed that differently oriented pileups are either under the same remote uniform loading, or under the same resolved shear stress along the pileup direction for any orientation of the interface. The distributions of dislocations and the lengths of pileups are substantially different for differently or...

This paper presents an empirical study to explore how firms invest in their IT infrastructure to support strategic flexibility. It investigates how IT infrastructure capabilities relate to strategic flexibility, how firms build flexibility into their IT investment decisions, and how the firms use IT to support strategic flexibility. Our cases indicate that different types of needed flexibility ...

An important issue in qualitative spatial reasoning is the representation of relative directions. In this paper we present simple geometric rules that enable reasoning about the relative direction between oriented points. This framework, the oriented point algebra OPRAm, has a scalable granularity m. We develop a simple algorithm for computing the OPRAm composition tables and prove its correctn...

in order to understand the impact of layer-wise scanning direction in the selective laser sintering process, test coupons were manufactured for mechanical testing from duraform™ polyamide powder. the effects of laser energy density, varying between 0.003 and 0.024 j/mm 2 were examined in test specimens rotated 90º through the z axis. sls machines do not always facilitate ‘cross-hatching’ of lay...

We present an ambiguous motion paradigm that allows us to quantify the influence of aspects of form relevant to the perception of apparent motion. We report on the role of bar element orientation in motion paths. The effect of orientation differences between bar elements in a motion path is small with respect to the crucial role of the orientation of bar elements relative to motion direction. M...

Cell shape has long been thought to be the main cue for spindle positioning in mitotic cells, but new evidence suggests that, in the context of an epithelium, tricellular junctions encode positional information that helps orient mitotic spindles.

this study intends to propose a modern model in the field of human resources (hr) strategic management through designing human resources’ competence framework. based on this strategic orientation of organization on human resources management system has been investigated considering the mediating role of competence approach in central bank of the islamic republic of iran. in order to implement a...
