When land parcel boundaries are surveyed for purposes of registration in most southern African countries, the cadastral survey records and diagrams prepared have to be examined and approved by the Surveyor General first before they can be registered in the Deeds Registries. For such records to be approved, their quality must conform to requirements stipulated in relevant acts and regulations. Where regulatory requirements are not met, the records are rejected and returned for corrections and resubmission. From a cross-organizational context, poor quality documents lodged upstream have the effect of congesting examination processes downstream as records are rejected and returned backwards due to quality failure. The paper proposes a quality performance measurement model to analyze quality performance in land administration work processes. The developed model is tested on 2 survey examination and approval sites and 3 deeds registration sites in Namibia, Zimbabwe and South Africa. Based on below expected quality results obtained at one of the sites, a root cause analysis was conducted to establish recurring and underlying causal factors upon which quality improvement strategies can be built on. 相似文献

The present liability system for managing environmental risks has had huge transaction costs through the courts with limited funds actually utilized for compensation (except to the lawyers) and cleanup of wastes. This paper discusses the use of insurance coupled with well-specified standards as an alternative to the current system. It illustrates the potential for the use of these policy tools in the context of two environmental risk management problems: providing liability protection to contractors involved in asbestos removal and protecting commercial property lenders and owners from liabilities associated with environmental contamination. 相似文献

A two period model of the training decision is analysed using a human capital approach. The segmented labour market model where training opportunities distinguish entrants is compared with a competitive structure with homogeneous entrants. The main conclusions in the paper are the clear effects of training wages and the different effects in the two market structures of both wages and employment prospects in the unskilled market on training. 相似文献

Alternative land management practices, including agroforestry, help to maintain levels of soil organic matter (SOM) and can facilitate soil carbon (C) sequestration for mitigating atmospheric CO2 emissions. This study quantified C inputs and determined the changes of the soil C pool in a 19-year-old Gliricidia sepium alley cropping system, studied at two fertiliser levels (tree prunings only [? N], and tree prunings plus chicken manure [+ N]), and was compared to a sole crop system. Carbon input from tree prunings ranged from 455 to 457 g C m? 2 y? 1, whereas C inputs from crop residues were similar between alley- and sole crops ranging from 121 to 159 g C m? 2y? 1. The soil organic C (SOC) pool in the alley crop was 16–23% higher than the sole crop. In the 19th year of alley farming, SOC was significantly higher (p < 0.05) in the alley crop (3.2%) compared to the sole crop (2.4%), and was also greater compared to that at the time of establishment of the agroforestry system (2.8%). Gross SOC turnover to a 20-cm depth ranged from 12 to 14 years in the + N and ?N alley crops compared to 49 and 50 years in the + N and ?N treatments for the sole crops. Residue stabilisation efficiency in the alley crops was 39% and 55% in + N and ?N treatments respectively. 相似文献

Targeting Conservation Investments in Heterogeneous Landscapes: A Distance-Function Approach and Application to Watershed Management 总被引:4,自引:0,他引:4

To achieve an environmental objective at least cost, decision makers must integrate information about spatially variable biophysical and economic conditions. Although the biophysical attributes that contribute to an environmental outcome are often known, the way in which these attributes interact to produce the outcome is often unknown. We introduce a nonparametric conservation targeting approach that relies on distance functions to cost-efficiently allocate conservation funds. We apply the approach empirically to the case of conservation contracting for water-quality objectives. The contract portfolios derived from the application have many desirable properties, including intuitive appeal and robust performance across plausible parametric scoring measures. 相似文献

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and nonagricultural commodities. A dynamic climate module is integrated into an economy‐wide model containing a detailed zonal level agricultural structure. This coupled climate‐economic model is used to evaluate the effects of climate variability on prospective irrigation and infrastructure investment strategies, and the ensuing country‐wide economy. The linkages between the dynamic climate module and the economic model are created by the introduction of a climate‐yield factor (CYF), defined at the crop level and varied across Ethiopian zones. Nine sets of variable climate (VC) data are processed by the coupled model, generating stochastic wet and dry shocks, producing an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country's future welfare under all investment strategies when climate variability is ignored. The coupled model ensemble is further utilized for risk assessment to guide Ethiopian policy and planning. 相似文献

This paper examines the class dynamics of food sovereignty in Mexico and Ecuador. It argues that the nature of contemporary demands for food sovereignty is heavily influenced by the outcomes of peasant movements’ historical and ongoing internal class dynamics. Processes of class differentiation within peasant organizations in both countries have led to the interests of certain classes predominating over or at the expense of others. Despite La Vía Campesina's projection of ‘unity in diversity’, incorporating sometimes conflicting class interests into the movement is particularly challenging. As such, class analysis must be brought back into debates around food sovereignty in order to gauge (and potentially further) the movement's transformative potential. 相似文献

Despite growing interest in emotions, organizational scholars have largely ignored the moral emotion of schadenfreude, which refers to pleasure felt in response to another’s misfortune. As a socially undesirable emotion, it might be assumed that individuals would be hesitant to share their schadenfreude. In two experimental studies involving emotional responses to unethical behaviors, we find evidence to the contrary. Study 1 revealed that subjects experiencing schadenfreude were willing to share their feelings, especially if the misfortune was perceived to be deserved (i.e., resulting from unethical behaviors). Study 2 extends this work by incorporating schadenfreude targets of different status (CEO versus employee). Consistent with the “tall poppy syndrome,” subjects were more willing to share schadenfreude concerning high status targets than low status targets when the perceived severity of the target’s misconduct was low. This status effect disappeared at higher levels of perceived deservingness, however. Reported willingness to share schadenfreude was strongest at these levels but did not differ significantly between high and low status targets. These findings build on the social functional account of emotions, suggesting that sharing schadenfreude may signal normative cues to others regarding workplace behaviors that are deemed to be unethical. 相似文献
