Discussions of manpower planning take place in the context either of national plans or of company plans. From time to time the view has been expressed that the coverage and the time scale of these two types of planning are so different that there is nothing in common between them. This paper considers whether, in practice, ‘manpower’ is really so different from ‘personnel’. After all, the individuals regarding whom both plans are made are the same people; in both cases the planners are concerned with the posts they are to fill, with their salaries and with their mobility.  相似文献

There has been considerable conceptual confusion about the differences between compassion fatigue and countertransference. This often results in them being treated as the same phenomena, both in the literature and clinically. This paper maintains that these are, in fact, two different concepts that derive from different sources and serve different functions. Each of these two concepts requires different kinds of interventions as well.  相似文献

This article examines the argument that gender mainstreaming offers the way forward for closing the gender pay gap. It juxtaposes research on the process of gender mainstreaming with our account of the processes involved in Australian state government Inquiries into the gender pay gap since the late 1990s. We indicate that the continuous process of analysis and response that gender mainstreaming can offer demands political will, intensive links between research and action, and adequate resources — which means that gender mainstreaming is seldom delivered in practice. We use our account of the Australian Inquiries to argue that, provided adequate political and financial resources are in place, the gender pay gap can be narrowed through the institutional mechanisms of an industrial relations system but that the regulatory approach is limited by its vulnerability to changes in industrial relations policy. The article concludes that, whatever strategy is used to narrow the gender pay gap, it must be able to show those who use and observe it that gender itself is a continuous, effortful and political process.  相似文献

Survey evidence for the Spanish population indicates that perceptions of lung cancer risk and life expectancy loss due to smoking are similar to estimates found in the United States. This paper also presents new evidence on the relative lung cancer risk for smokers, the perceived risk of lung disease for smokers, the heart disease risk for smokers, and the relative heart disease risk for smokers, all of which indicate substantial risk perceptions. Risk beliefs are particularly high for younger respondents, but are lower for better educated respondents.  相似文献

Quantitative microbial risk assessment was used to predict the likelihood and spatial organization of Mycobacterium tuberculosis ( Mtb ) transmission in a commercial aircraft. Passenger exposure was predicted via a multizone Markov model in four scenarios: seated or moving infectious passengers and with or without filtration of recirculated cabin air. The traditional exponential ( k  = 1) and a new exponential ( k  = 0.0218) dose-response function were used to compute infection risk. Emission variability was included by Monte Carlo simulation. Infection risks were higher nearer and aft of the source; steady state airborne concentration levels were not attained. Expected incidence was low to moderate, with the central 95% ranging from 10−6 to 10−1 per 169 passengers in the four scenarios. Emission rates used were low compared to measurements from active TB patients in wards, thus a "superspreader" emitting 44 quanta/h could produce 6.2 cases or more under these scenarios. Use of respiratory protection by the infectious source and/or susceptible passengers reduced infection incidence up to one order of magnitude.  相似文献

The natural South Florida system II: Predrainage ecology   总被引:2,自引:0,他引:2

The goal of the South Florida restoration process is to reestablish a sustainable ecological system that approximates the predrainage system (i.e., the system that existed before canals and water control structures were built). A critical step in the restoration process is to describe the predrainage system with sufficient detail to capture the essential landscape features (e.g., space, connectivity, patterns) that gave the region its defining character and supported its natural abundance and diversity of plants and wildlife.A previous attempt at reconstruction of predrainage (circa 1870) vegetation patterns covered only the Everglades (Davis et al., 1994) but introduced a concept of landscape mosaics that should be extended to South Florida. We propose 16 landscape units that include freshwater landscapes, upland landscapes, coastal wetlands, and estuaries (particularly Florida and Biscayne Bays), the Florida Keys and Reef Tract, and the Inner Southwest Florida Shelf.The predrainage area, because of its enormous size, supported a landscape heterogeneity that was advantageous to animals with several distinct habitat-related life strategies. Five species have been selected to illustrate different dependencies on landscape patterns in predrainage South Florida: wood stork (Mycteria americana), American alligator (Alligator mississippiensis), snail kite (Rostrhamus sociabilis), Cape Sable seaside sparrow (Ammodramus maritimus mirabilis), and pink shrimp (Penaeus duorarum). As individuals or as populations, these animals operated across several spatial and temporal scales. The predrainage system's large spatial extent and complex hydropatterns allowed wood storks and other animals with large feeding ranges to take advantage of the strongly seasonal rainfall pattern, while at the same time providing a refuge somewhere in the system for survival of all other species. Landscape heterogeneity and large spatial extent promoted the region's natural wildlife abundance and species diversity.  相似文献

Preferences for state opting out are thought of as being the expression of underpinning conflicts of states national identity, empirical evidence on its underlying behavioural processes is scarce. This paper draws upon evidence form the Basque Country to examine the support for a hypothetical opting out from the Spanish State in the light of a reformulation of [Ackerlof, G.A., Kranton, R.E., 2000. Economics and Identity. Quarterly Journal of Economics, 115, 715–753]. We use representative survey data from the Spanish Institute of Sociological Research for the Basque Country. To adjust our empirical specification to the prevalent hypothesis we employ a recursive seemingly unrelated probit approach. Our results suggest evidence for a simultaneous and endogenous influence of national identity on political preferences for the opting out of the Basque Country from Spain. We find evidence consistent with an instrumental conception of identity as motivating preferences for nation-state opting out, and status quo bias.  相似文献

The current literature on the relationship between income and environmental quality is dominated by a notion of an inverted 'U'-shaped curve between both variables. However, a key variable is missing in this kind of study: the extra-territorial environmental effects of national economies. International trade of raw materials may be a good proxy to estimate these 'environmental load displacement' effects. The present work tries to elucidate some patterns in the relationship between economic growth in affluent countries and the quantity of non-renewable materials imported from less-developed countries. The results indicate that a general de-linking between economic growth and Southern resource consumption is not occurring in the industrialized world. Thus, developed countries may be increasingly displacing the environmental costs associated with material throughput to poorer regions of the world.  相似文献
