Questioning the Notion of Feminine Leadership: A Critical Perspective on the Gender Labelling of Leadership

GENDER, WORK & ORGANISATION, Issue 3 2000
Yvonne Due Billing
Traditionally, leadership has been equated with masculinity. Managerial jobs, at least in business and on senior levels, have been defined as a matter of instrumentality, autonomy, result-orientation, etc. something which is not particularly much in line with what is broadly assumed to be typical for females. Today, however, there seems to be a broad interest in leadership being more participatory, non-hierarchical, flexible and group-oriented. These new ideas on leadership are often seen by students of gender as indicating a feminine orientation. This article argues that it is necessary to critically discuss the whole idea of gender labelling leadership as masculine or feminine and suggests that we should be very careful and potentially aware of the unfortunate consequences when we use gender labels. Constructing leadership as feminine may be of some value as a contrast to conventional ideas on leadership and management but may also create a misleading impression of women's orientation to leadership as well as reproducing stereotypes and the traditional gender division of labour.

Climate change-driven forest fires marginalize the impact of ice cap wasting on Kilimanjaro

GLOBAL CHANGE BIOLOGY, Issue 7 2005
Andreas Hemp
Abstract The disappearing glaciers of Kilimanjaro are attracting broad interest. Less conspicuous but ecologically far more significant is the associated increase of frequency and intensity of fires on the slopes of Kilimanjaro, which leads to a downward shift of the upper forest line by several hundred meters as a result of a drier (warmer) climate since the last century. In contrast to common belief, global warming does not necessarily cause upward migration of plants and animals. Here, it is shown that on Kilimanjaro the opposite trend is under way, with consequences more harmful than those due to the loss of the showy ice cap of Africa's highest mountain. [source]

Working More Productively: Tools for Administrative Data

HEALTH SERVICES RESEARCH, Issue 5 2003
Leslie L. Roos
Objective. This paper describes a web-based resource (http://www.umanitoba.ca/centres/mchp/concept/) that contains a series of tools for working with administrative data. This work in knowledge management represents an effort to document, find, and transfer concepts and techniques, both within the local research group and to a more broadly defined user community. Concepts and associated computer programs are made as "modular" as possible to facilitate easy transfer from one project to another. Study Setting/Data Sources. Tools to work with a registry, longitudinal administrative data, and special files (survey and clinical) from the Province of Manitoba, Canada in the 1990,2003 period. Data Collection. Literature review and analyses of web site utilization were used to generate the findings. Principal Findings. The Internet-based Concept Dictionary and SAS macros developed in Manitoba are being used in a growing number of research centers. Nearly 32,000 hits from more than 10,200 hosts in a recent month demonstrate broad interest in the Concept Dictionary. Conclusions. The tools, taken together, make up a knowledge repository and research production system that aid local work and have great potential internationally. Modular software provides considerable efficiency. The merging of documentation and researcher-to-researcher dissemination keeps costs manageable. [source]

Climate change and its impact on the forests of Kilimanjaro

AFRICAN JOURNAL OF ECOLOGY, Issue 2009
Andreas Hemp
Abstract Cloud forests are of great importance in the hydrological functioning of watersheds in subhumid East Africa. However, the montane forests of Mt. Kilimanjaro are heavily threatened by global change impacts. Based on an evaluation of over 1500 vegetation plots and interpretation of satellite imagery from 1976 and 2000, land-cover changes on Kilimanjaro were evaluated and their impact on the water balance estimated. While the vanishing glaciers of Kilimanjaro attract broad interest, the associated increase of frequency and intensity of fires on the slopes of Kilimanjaro is less conspicuous but ecologically far more significant. These climate change-induced fires have lead to changes in species composition and structure of the forests and to a downward shift of the upper forest line by several hundred metres. During the last 70 years, Kilimanjaro has lost nearly one-third of its forest cover, in the upper areas caused by fire, on the lower forest border mainly caused by clearing. The loss of 150 km2 of cloud forest , the most effective source in the upper montane and subalpine fog interception zone , caused by fire during the last three decades means a considerable reduction in water yield. In contrast to common belief, global warming does not necessarily cause upward migration of plants and animals. On Kilimanjaro the opposite trend is under way, with consequences more harmful than those due to the loss of the showy ice cap of Africa's highest mountain. [source]

Use of nitrocellulose films for affinity-directed mass spectrometry for the analysis of antibody/antigen interactions

RAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 18 2001
Shuqing Sun
Combination of affinity extraction procedures with mass spectrometric analyses is termed affinity-directed mass spectrometry, a technique that has gained broad interest in immunology and is extended here with several improvements from methods used in previous studies. A monoclonal antibody was immobilized on a nitrocellulose (NC) membrane, allowing the corresponding antigen to be selectively captured from a complex solution for analysis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS). This method was also used to rapidly determine the approximate binding region responsible for the antibody/antigen interaction. The tryptic fragments of antigen protein in buffer were applied to the antibody immobilized on NC film and allowed to interact. The NC film was then washed to remove salts and other unbound components, and subjected to analysis by MALDI-TOFMS. Using interferon-,2a and anti-interferon-,2a monoclonal antibody IgG as a model system, we successfully extracted the antigen protein and determined the approximate binding region for the antigen/antibody interaction (i.e., the tryptic fragment responsible).
