Development debates have been greatly influenced by the growth consensus: the conventional wisdom that economic growth should be the primary priority for less-developed countries (LDCs) because it most effectively improves the well-being of the world’s poor. We compare the impact of growth to other independent variables in an unbalanced panel analysis of up to 109 LDCs and 580 observations across six time points (1980, 1985, 1990, 1995, 2000, and 2003). Our dependent variables include caloric consumption, infant survival probability, one-to-five year survival probability, female life expectancy, and male life expectancy. First, we find that gross domestic product (GDP) has significant positive effects on caloric consumption, female life expectancy, and male life expectancy. Second, GDP does not have robust effects on infant and one-to-five survival probabilities. Third, fertility, urbanization, and secondary school enrollment have larger effects than GDP in the majority of models. The more powerful effects of fertility, urbanization, and secondary schooling cannot simply be attributed to an indirect effect of GDP. Fourth, we find that dependency variables do not have robust significant effects. Fifth, over time, GDP has become much less effective at improving caloric consumption and infant and one-to-five survival. We infer that there are serious limitations to concentrating exclusively on economic growth to improve well-being in LDCs. 相似文献

This article argues that, despite environmental issues climbing higher on the political agenda and considerable recent policy activity, rhetoric is not matched by reality in our efforts to manage the Australian environment. We integrate the imperatives emerging from the policy and sustainability literatures and from actual policy, with detailed work on wildlife conservation in Victoria's Central Highlands. Our analysis demonstrates that, rather than undertaking the more intensive policy and 'adaptive management' that is needed, governments are often doing less and may actually be 'taking their hands of their wheel'. Some public policy and administration implications of the emerging policy field of sustainability are illustrated. 相似文献

The polymerase chain reaction (PCR) method of specific gene amplification was used in casework to synthesize millions of copies of the polymorphic second exon of the human leukocyte antigen (HLA)-DQ alpha (or DQA1) locus from a variety of evidence samples. The HLA-DQ alpha allelic variants in the amplified deoxyribonucleic acid (DNA) were determined in a rapid non-radioactive test by hybridization to sequence-specific oligonucleotide probes in both the dot-blot and reverse dot-blot formats. This genetic typing system has been subjected to blind proficiency testing; the performance of this test in the analysis of experimentally mixed samples was also evaluated. As of August 1990, over 250 cases have been tested and more than 2000 individual evidence (bloodstains, semen stains, individual hairs, bone fragments, and tissue sections) and reference samples have been analyzed. The first 198 of these cases are summarized in this paper; in 65% of the cases with conclusive results a suspect was included, and in 35%, all suspects were excluded. Individual cases as well as some of the general issues relating to forensic science analysis and this genetic typing system are discussed. The high rate of exclusion reported here combined with the ability of PCR to type old evidence samples suggests the relevance of this genetic test for postconviction review; two cases in which the convicted suspect was excluded are discussed. 相似文献

An improved method has been developed for the reliable classification of different C1R genetic variant forms from human serum or plasma. The method combines the use of neuraminidase-digested samples followed by monodimensional isoelectric focusing in the pH range 5 to 8 followed by immunoblotting. The method yields a simple pattern, with one major band in homozygote and two major bands in heterozygote cases. 相似文献

The terminology of “civil society” has gained currency in recent discussions of democratic movements around the globe. Although
less grandiose in its implications than claims about the “end of history,” this terminology does suggest a certain universality
in human experience. We argue that this claim of universality is warranted, but also problematic. We establish the relevance
of our argument in reference to the literatures in African and Indian studies.
We note first that the common employments of the concept ignore the theoretical and historical specificity of civil society:
civil society is used to label any group or movement opposed to the state, regardless of its intent or character, or used
so generically that it is indistinguishable from the term “society.” Instead, we argue that civil society is a sphere of social
life, involving a stabilization of a system of rights, constituting human beings as individuals, both as citizens in relation
to the state and as legal persons in the economy and the sphere of private association.
Thus, we link the wide resonance of the concept to its embeddedness in the logic of liberal capitalist society and the capitalist
global division of labor. This conception allows us to see that, although the emergence of a sphere of civil society involves
at least minimal democranization and is supportive of struggles for further democratization, the status of democracy is also
made quite problematic by the tensions endemic to liberal capitalism and the processes of uneven development within international
capitalism. Our usage also allows us to distinguish more clearly movements dedicated to the construction of civil society
from those that may count actually as counter-civil society movements.

Alcoholism and drug addiction affects the entire family. At least 22 million Americans have been raised in an alcoholic environment. Parental alcoholism and/or addiction can have profound emotional and psychological scars on the children. These homes are often characterized by emotional and or physical insecurity, loneliness, terror and inconsistency. The children from these homes often are extremely insecure have low self-esteem, and have a variety of emotional problems. Adolescents from addictive homes are over-represented in juvenile court as status offenders, delinquents and abuse and neglect cases. This article will discuss this issue and implications for the juvenile justice system and personnel working with these youth 相似文献
