'Work and Emancipatory Practice: Towards a Recovery of Human Beings' Productive Capacities,'

This article argues that productive work represents a mode of human flourishing unfortunately neglected in much current political theorizing. Focusing on Habermasian critical theory, I contend that Habermas’s dualist theory of society, on account of the communicative versus instrumental reason binary which underpins it, excludes work and the economy from ethical reflection. To avoid this uncritical turn, we need a concept of work that retains a core emancipatory referent. This, I claim, is provided by Alasdair MacIntyre’s notion of ‘practice’. The notion of ‘practice’ is significant in suggesting an alternative conception of human productivity that is neither purely instrumental nor purely communicative, but rather both simultaneously, a form of activity which issues in material products and yet presumes a community of workers engaged in intersubjective self-transformation. However, we can endorse MacIntyre’s notion of ‘practice’ only if we reject his totalizing anti-modernism and insist on the emancipatory potentialities of modern institutions.

Evaluation and outcome of patients with chronic non-productive cough using a comprehensive diagnostic protocol

Background-Asthma, post-nasal drip syndrome (PNDS), and gastrooesophageal reflux (GOR) account for many cases of chronic non-productive cough (CNPC). Each may simultaneously contribute to cough even when clinically silent, and failure to recognise their contribution may lead to unsuccessful treatment.

Methods—Patients (all lifetime non-smokers with normal chest radiographs and spirometric measurements) referred with CNPC persisting for more than three weeks as their sole respiratory symptom underwent histamine challenge, home peak flow measurements, ear, nose and throat (ENT) examination, sinus CT scanning, and 24 hour oesophageal pH monitoring. Treatment was prescribed on the basis of diagnoses informed by investigation results.

RESULTS—Forty three patients (29 women) of mean age 47.5 years (range 18-77) and mean cough duration 67 months (range 2-240) were evaluated. On the basis of a successful response to treatment, a cause for the cough was identified in 35 patients (82%) as follows: cough variant asthma (CVA) (10 cases), PNDS (9 cases), GOR (8cases), and dual aetiologies (8 cases). Histamine challenge correctly predicted CVA in 15 of 17 (88%) positive tests. ENT examination and sinus CT scans each had low positive predictive values for PNDS (10 of 16 (63%) and 12 of 18 (67%) positive cases, respectively), suggesting that upper airways disease frequently co-exists but does not always contribute to cough. When negative, histamine challenge and 24 hour oesophageal pH monitoring effectively ruled out CVA and GOR, respectively, as a cause for cough.

CONCLUSION—This comprehensive approach aids the accurate direction of treatment and, while CVA, PNDS and GOR remain the most important causes of CNPC to consider, a group with no identifiable aetiology remains.

PREDICTION OF NETILMICIN DISPOSITION IN NEONATES

Multiple regression analyses of data from 33 neonates who received netilmicin therapy showed that concurrent treatment with other drugs (Drg), creatinine clearance (CL(cr)), gestational age (GA), and an apgar score of less than 6 at 1 min (Agl') were significant determinants of netilmicin clearance. Apparent volume of distribution was significantly affected by postnatal age (PNA), gender, the presence of ascites and/or oedema (A/O), and whether or not the neonate was small for gestational age (SGA). The following formulae were obtained: CL (ml min-1 kg-1) = -0.108 - 0.210 (Drg) + 0.152(CL(cr)) + 0.019(GA) -0.128(Agl') (multiple R = 0.725, p
