Time Out of Work and Skill Depreciation

This paper investigates the role of skill depreciation in the relationship between work interruptions and subsequent wages. Using a unique longitudinal dataset, the Swedish part of the International Adult Literacy Survey, we are able to analyze changes in literacy skills for individuals as a function of time out of work. In general, we find statistically strong evidence on a negative relationship between work interruptions and skills. Our analysis suggests that depreciation of general (literacy) skills is economically significant. Our estimates imply that a full year of non-employment is associated with skill losses that are equivalent to moving 5 percentiles down the skill distribution.Work interruptions; Skill depreciation; Unemployment; Wage differentials

Time out of work and skill depreciation

This paper investigates the role of skill depreciation in the relationship between work interruptions and subsequent wages. Using unique longitudinal microdata containing information on the ability to understand and practically employ printed information, we are able to analyze changes in skills for individuals as a function of time out of work. In general, we find statistically strong evidence of a negative relationship between work interruptions and skills. Our analysis suggests that depreciation of general information-processing skills is economically significant, with a full year of non-employment being equivalent to moving 5 percentiles down the skill distribution.Work interruptions; skill depreciation; wage differentials

Forwarding a challenging task: Seven elements for capacity development for disaster risk reduction

Capacity development for disaster risk reduction is an important process to substantially reduce disaster losses, which threaten sustainable development and the achievement of the Millennium Development Goals. This paper presents seven elements for capacity development for disaster risk reduction that has been applied in practise with noteworthy results. The seven elements are: (1) Terminology, (2) Local context, (3) Ownership, (4) Capacity assessment, (5) Roles and responsibilities, (6) Mix of activities, and (7) Monitoring, evaluation and learning. Although this set of elements should not be seen as a comprehensive methodology in itself, the seven elements for capacity development for disaster risk reduction still highlight vital aspects and seem to be a both conceptually and pragmatically interesting path to follow for increasing the impact and sustainability of projects

Challenging disparities in capacity development for disaster risk reduction

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and guidelines found in available theory. The analysis of data from thirty-five qualitative semi-structured interviews reveals that there are gaps between theory and practise, as well as between the practitioners, in all seven elements identified in available theory. There is ambiguity regarding terminology, different views about the meaning of local context, ownership and capacity assessment, as well as contradicting opinions of the role and responsibilities of external partners. Focus is on training individuals, while other requisites are often ignored, and there is a general lack of understanding of what results to assess and how to monitor and evaluate projects

Skokie, the ACLU and the Endurance of Democratic Theory

ZnO nanorods (NRs) with high surface area to volume ratio and biocompatibility is used as an efficient photosensitizer carrier system and at the same time providing intrinsic white light needed to achieve cancer cell necrosis. In this letter, ZnO nanorods used for the treatment of breast cancer cell (T47D) are presented. To adjust the sample for intracellular experiments, we have grown the ZnO nanorods on the tip of borosilicate glass capillaries (0.5 mu m diameter) by aqueous chemical growth technique. The grown ZnO nanorods were conjugated using protoporphyrin dimethyl ester (PPDME), which absorbs the light emitted by the ZnO nanorods. Mechanism of cytotoxicity appears to involve the generation of singlet oxygen inside the cell. The novel findings of cell-localized toxicity indicate a potential application of PPDME-conjugated ZnO NRs in the necrosis of breast cancer cell within few minutes

Assessing electron beam sensitivity for SrTiO3 and La0.7Sr0.3MnO3 using electron energy loss spectroscopy

Thresholds for beam damage have been assessed for La0.7Sr0.3MnO3 and SrTiO3 as a function of electron probe current and exposure time at 80 and 200 kV acceleration voltage. The materials were exposed to an intense electron probe by aberration corrected scanning transmission electron microscopy (STEM) with simultaneous acquisition of electron energy loss spectroscopy (EELS) data. Electron beam damage was identified by changes of the core loss fine structure after quantification by a refined and improved model based approach. At 200 kV acceleration voltage, damage in SrTiO3 was identified by changes both in the EEL fine structure and by contrast changes in the STEM images. However, the changes in the STEM image contrast as introduced by minor damage can be difficult to detect under several common experimental conditions. No damage was observed in SrTiO3 at 80 kV acceleration voltage, independent of probe current and exposure time. In La0.7Sr0.3MnO3, beam damage was observed at both 80 and 200 kV acceleration voltages. This damage was observed by large changes in the EEL fine structure, but not by any detectable changes in the STEM images. The typical method to validate if damage has been introduced during acquisitions is to compare STEM images prior to and after spectroscopy. Quantifications in this work show that this method possibly can result in misinterpretation of beam damage as changes of material properties

An Embodied question answering system for use in the treatment of eating disorders

This paper presents work in progress on implementing an embodied question answering system, Dr. Cecilia, in the form of a virtual caregiver, for use in the treatment of eating disorders. The rationale for the system is grounded in one of the few effective treatments for anorexia and bulimia nervosa. The questions and answers database is encoded using natural language, and is easily updatable by human caregivers without any technical expertise. Matching of users' questions with database entries is performed using a weighted and normalized n-gram similarity function. In this paper we give a comprehensive background to and an overview of the system, with a focus on aspects pertaining to natural language processing and user interaction. The system is currently only implemented for Swedish

Outer Space Resources in Efficient and Equitable Use: New Frontiers for Old Principles

A regime for managing the two space resources, the physical space resources and the electromagnetic spectrum was suggested. To achieve efficiency in an international convention establishing intra- and international free trade in divisible, indefinite user rights to the complete resources should be agreed upon. A legal convention on the definition and enforcement of liability rules is also crucial for efficiency. An authority to manage space resources is needed only for those activities that interfere with a large number of other activities. The creation of an international space condominium to auction user rights to the two resources was suggested to achieve equity
