This article is concerned with the question of whether participation in the global economy leads to sustainable income growth. It examines the furniture industry of Central Java, which has grown rapidly since the financial crisis in 1997. The article shows that the exporting small and medium-sized enterprises generated substantial employment and income growth. However, this growth is not sustainable because the viability of exports has become dependent on wood which is logged illegally and risks depletion. Government and donor projects aimed at small enterprises risk driving these enterprises deeper into the race to the bottom. The article then discusses ways to avoid this, stressing the need for a coalition of public and private actors along the local–global axis. 相似文献

Metal and metalloid multi-elementary ICP-MS validation in whole blood, plasma, urine and hair. Reference values 总被引:5,自引:0,他引:5

Four multi-elementary metal and metalloid quantification methods using inductively coupled plasma mass spectrometry (ICP-MS) were developed and validated in human whole blood, plasma, urine and hair by means of a single preparation procedure for each sample. The ICP-MS measurements were performed using a Thermo Elemental X7CCT series and PlasmaLab software without a dynamic reaction cell. With this procedure 27-32 elements can be simultaneously quantified in biological matrices: Li, Be, B, Al, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Mo, Pd, Ag, Cd, Sn, Sb, Te, Ba, W, Pt, Hg, Tl, Pb, Bi, U. Whole blood, plasma and urine samples (0.4 ml each) were diluted with purified water, acid, triton X100 and butanol. Rhodium was used as internal standard. The urine sample results were corrected for enzymatic creatinine determination. Twenty-five milligrams hair samples were acid mineralized after a decontamination procedure and diluted as previously described for biological fluids. To be validated, each element had to show linearity with a correlation coefficient higher than 0.99. The intra-assay and inter-assay inaccuracy, measured as the variation coefficient, were below 5 and 10% respectively. Global performance was assessed by a quality control program. Our laboratory is a registered participant of the Institut National de Santé Publique du Québec (Sainte-Foy, Canada) inter-laboratory comparison program for whole blood, urine, and beard hair of non-occupationally exposed individuals spiked with selected elements. In our study multi-element metal and metalloid analysis was assessed for 27 elements in whole blood, 27 elements in plasma, 30 elements in urine and 32 elements in hair, from 0 to 25, or 250 to 1000 ng/ml, depending on the element. Quantification limits ranged from 0.002 ng/ml (U) to 8.1 ng/ml (Al) for whole blood, from 0.002 ng/ml (U) to 7.7 ng/ml (Al) for plasma, from 0.001 ng/ml (U) to 2.2 ng/ml (Se) for urine, and from 0.2 pg/mg (Tl) to 0.5 ng/mg (B) for hair. Normal values were determined in whole blood (n=100), plasma (n=100), urine (n=100), and hair (n=45) of healthy volunteers, leading to approximately 10,000 analyses. All results are presented and discussed. Clinical toxicology and forensic toxicology applications are also reported. ICP-MS has made significant advances in the field of clinical biology, particularly in toxicological analysis. This is due to the use of extremely effective equipment that permits better clinical and forensic toxicological analysis of metal and metalloid status of each individual patient. 相似文献

Many of the most active regions in terms of commercial paradiplomacy are home to influential nationalist movements: Scotland and Quebec are cases in point. Conversely, many rich and export-oriented regions, such as South East England in the United Kingdom or Ontario in Canada, remain less active, if at all, in this domain. Nevertheless, the influence of nationalism as a driving force behind the practice of commercial paradiplomacy by subnational entities has often been subordinated to other variables such as ‘trade openness’ (exports as part of GDP) or ‘asymmetry’ with national economic interests (export and FDI partners). This article describes the development of autonomous commercial paradiplomacy apparatuses in Quebec and Scotland by focusing on nationalism as a crucial motive, which is also partly responsible for the way such apparatuses developed, through the establishment of organizations and strategies institutionally distinct from those of the ‘rest’ of Canada and the UK. 相似文献

Although numerous writers have discussed the importance of and link between juror characteristics and juror decisions in rape trials, anempirical investigation of the relationships between these characteristics and juror verdicts has not been made. Using data obtained from a sample of 896 citizens serving as mock jurors, the principal focus of the present research was on the correlations of jurors' background characteristics and their attitudes toward rape with their decisions in a simulated rape case. Results of the study showed that the jurors' background and attitudinal variables were associated with their decisions. In addition, the pattern of the correlations was quite stable as the characteristics of the case evaluated (in terms of defendant and victim race, victim physical attractiveness, victim sexual experience, strength of evidence presented, and type of rape committed) were found to have only negligible effects on these relationships. Other tests showed that only the attitudinal variables accounted for differences in the jurors' decisionsafter characteristics of the case had been considered. Further, as compared to background data, the jurors' views of rape were the most important predictor of their decisions. Implications of the role of jurors' views of rape in jurors' decisions in rape trials and the use of rape attitudes for selecting jury members in rape cases discussed. 相似文献
