The concern driving current debate on agricultural extension is increasingly that of how to help farmers learn how to deal with the complex world around them responsibly and profitably, in such a way that the extension worker is ancillary. This article seeks to deconstruct and provide a more reasoned assessment of agricultural extension services through a reflection on development paradigms, adult education, individual empowerment, and institutional pluralism. By calling into question the underlying ethical dimensions of agricultural extension, it is possible to develop an alternative paradigm and thereby generate new insights into it. The article concludes that the raison d'être of agricultural extension today must be to create an ethical basis which ensures that extension practices are more inclusive and thus responsive to the needs of farmers and other rural populations, integrating individual expectations into the wider socio-economic, cultural, political, and geographical environment.  相似文献

Knowing and understanding company objectives will not help employees solve every work-related problem, but, in the long run, such knowledge will contribute to more efficient and productive operations.  相似文献

The maintenance of welfare state policies requires citizen support for the provision of a social safety net through taxation and redistribution. Research has shown that a diverse political polity presents a risk to the welfare state; however, Canada bucks the trend and does not see citizen support for economic redistribution decline in response to immigration-based population diversity. Using Canada as our case, we argue that scholars of welfare state politics and redistribution should turn their attention to other sources of population heterogeneity in an effort to better understand how different political cleavages affect citizens’ redistributive preferences. We use an online experimental survey to manipulate the in-group identity of 500 Canadians. The survey enables respondents to identify with other in-group identities along regional, linguistic, income-group, and urban/rural characteristics. Our results find that while Canadians do have a strong baseline preference for redistributive behaviour, regional and linguistic cleavages moderate this outcome.  相似文献

In the aftermath of the Arab uprisings Foreign Terrorist Fighters (FTFs) have emerged as a significant security challenge. Since the 1980s and the Soviet occupation of Afghanistan the notion of a ‘foreign fighter’ has been closely linked, if not synonymous, with those ideologically or religiously motivated individuals who have travelled to join conflicts in Islamic lands. This article will explore the contemporary FTF movement, offering a comparison of Afghanistan in the 1980s and Syria in the contemporary period. It will explore the international community’s expansive responses to the challenge of FTFs, with special focus on the role of the United Nations.  相似文献

The recent formation of a United Kingdom and Irish working group, the Body Fluids Forum (BFF), highlighted the need to investigate different working practices prior to any inter-laboratory comparison work and identification of best practice. Various dilutions of semen were seeded onto swabs and cloth samples for each BFF member laboratory to test using their standard techniques. The results showed that the detection of acid phosphatase on swabs is best achieved using direct testing rather than on an extract from the swab. Extraction methods for spermatozoa require a balance to be achieved between using a sufficient volume of water to ensure optimal release and minimal volume to ensure a concentrated extract. PSA tests were investigated and found to be more sensitive than Choline. DNA profiles were obtained from samples in which no spermatozoa had been detected during microscopic examination.  相似文献

Abstract: Recently a small sampled cadaver study (n = 4) suggested that the human eyeballs are placed closer to the orbital roof and lateral orbital wall as first reported in the anatomical literature many years previously. This contrasts with central positioning of the eyeball within the orbit as advocated by the facial approximation literature. Given the limits of such small samples, this study re-examined globe position in nine new cadavers to help clarify which relationship is accurate. The results essentially confirm prior empirical findings except that the mean lateral divergences from the orbit center were found to be larger—the eyeball was found to be “displaced” 1.4 mm superiorly and 2.4 mm laterally. Medians calculated across all 13 cadavers from this study and the above-mentioned recent report refine these measurements to 1.4 and 2.3 mm respectively. Globe projection values were identical to those observed for living individuals (c. 16 mm).  相似文献
