The outcomes of various modes of administration may be summarized as follows:
  • 1 Under both ministerial and departmental control, the prior experience and predispositions of the Minister were critical factors affecting the colleges. Under departmental control, the background and attitudes of senior officers within the department were also important. Various instances of this were cited.
  • 2 There tended to be proportionately fewer dismissals of principals or resignations in protest by them under departmental control than when colleges were controlled by Ministers of the Crown or governing councils. Several reasons for this trend were suggested.
  • 3 Under all systems of control the colleges were subject from time to time to direct or indirect political pressure. For example, there were instances in which parents invoked or attempted to invoke political pressure to save their sons from expulsion from a college. Such pressures played a part in the dismissal or resignation of several principals.
  • 4 Another factor which led to the resignation of two principals who were directly responsible to a Minister was the belief that their jurisdiction had been transgressed by another senior public servant.
  • 5 Under departmental control a principal was likely to be caught up in intradepartmental politics. The fortunes of the college depended somewhat upon his success in this arena.
  • 6 In determining the policies and practices to be adopted on the college farm, a principal generally had greater freedom under Education Department control than under Agriculture Department control. On the other hand, teaching practices were generally subject to closer departmental supervision in the former case than in the latter.
  • 7 One problem with any system of control is that of maintaining a balance between continuity in policy on the one hand and sensitivity to demands for change on the other. In general, control over the colleges by government departments or governing councils tended to be conservative in emphasis, to stress continuity. By contrast, where control was directly exercised by Ministers of the Crown and where there were relatively frequent changes in incumbency of the relevant portfolio, continuity in policy was less assured.
  • 8 The life of advisory committees was typically marked by early enthusiasms and influence in dealing with urgent matters of policy. After these matters had been dealt with there was generally a decline in activity and influence, growing disillusion among members, and eventually reconstitution or replacement of the committee.

A simple method for analyzing nitrite in urine has been developed to confirm and quantify the amount of nitrite in potentially adulterated urine samples. The method involved separation of nitrite by capillary electrophoresis and direct UV detection at 214 nm. Separation was performed using a bare fused silica capillary and a 25 mM phosphate run buffer at a pH of 7.5. Sample preparation consisted of diluting the urine samples 1:20 with run buffer and internal standard, and centrifuging for 5 min at 2500 rpm. The sample was hydrodynamically injected, then separated using -25 kV with the column maintained at 35 degrees C. The method had upper and lower limits of linearity of 1500 and 80 microg/mL nitrite, respectively, and a limit of detection of 20 microg/mL. The method was evaluated using the National Committee for Clinical Laboratory Standards (NCCLS) protocol (Document EP10-A2), and validated using controls, standards, and authentic urine samples. Ten anions, ClO-, CrO4(-2), NO3-, HCO3-, I-, CH3COO-, F-, SO4-, S2O8(-2), and Cl-, were tested for potential interference with the assay. Interferences with quantitation were noted for only CrO4(-2) and S2O8(-2). High concentrations of Cl- interfered with the chromatography. The method had acceptable accuracy, precision, and specificity.  相似文献

Reported is a case of an assault causing extensive blunt force injuries in which the clinical, radiologic, and postmortem findings were all consistent with death resulting from brain damage arising from the assault. The assailant was charged with murder. Subsequent full neuropathologic (including histologic) examination revealed the unsuspected finding of a widespread meningoencephalitis but no evidence of significant traumatic brain damage. The contributions of the infective process and of the trauma to death were felt to be unclear and a guilty plea to attempted murder was accepted. This case highlights the importance of a full neuropathologic examination, including histology, in cases of trauma to the head, even when the cause of death may initially appear obvious.  相似文献

Really Responsive Regulation seeks to add to current theories of enforcement by stressing the case for regulators to be responsive not only to the attitude of the regulated firm but also to the operating and cognitive frameworks of firms; the institutional environment and performance of the regulatory regime; the different logics of regulatory tools and strategies; and to changes in each of these elements. The approach pervades all the different tasks of enforcement activity: detecting undesirable or non-compliant behaviour; developing tools and strategies for responding to that behaviour; enforcing those tools and strategies; assessing their success or failure; and modifying them accordingly. The value of the approach is shown by outlining its potential application to UK environmental and fisheries controls. Putting the system into effect is itself challenging but failing to regulate really responsively can constitute an expensive process of shooting in the dark.  相似文献

The objective of this paper is to determine the effects of farm tractorisation on output and human labour employment on Punjab farms in India. The residts seem to suggest that, this far, the use of tractors has resulted in higher output and more employment. The authors believe that the threat from farm tractorisation is not all that great; the use of tractors is likely to be confined to certain areas only, and there too, any displacement of labour should be possible to control through appropriate public policies.  相似文献
