Carbohydrate-based templates for synthetic vaccines and drug delivery

Methyl tetra-O-allyl, and tetra-O-[2-(tetrahydro-2H-pyranyl)oxy.-3-oxapentyl glucosides, and tetra-O-(cyanoethyl)galactosyl azide were converted into derivatives containing linkers with terminal carboxylic acid functionalities at the anomeric position and bearing four arms with phthaloyl- or BOC-protected terminal amino groups. These molecules were suitable for use in solid-phase peptide synthesis and for the preparation of dendrimers, containing multiple copies of peptides. (C) 2001 Elsevier Science Ltd.

Telemedicine and clinical genetics: establishing a successful service

There is a surprising lack of published experience on the use of videoconferencing in clinical genetics. Patients were randomly allocated to either a telegenetic (cases) or face-to-face (control) conventional clinic. The telegenetic consultation was done by videoconferencing, using ISDN lines at 384 kbit/s. Evaluation by the doctor and counsellor took place immediately after each appointment. The patient was asked to evaluate the appointment by telephone questionnaire about four weeks after the event. Forty-two patients were invited to participate and 33 (79%) returned their consent forms. Four patients declined to participate and were seen in ordinary face-to-face clinics. Preliminary results showed that the assessment of the telegenetics consultations by doctors, counsellors and patients was very favourable, and they responded positively when asked if they would be happy to use telemedicine in the future. For use in selected consultations, videoconferencing does appear to fulfil a useful role in clinical genetics.

Videoconferencing in the Queensland health service

Videoconferencing was introduced in the Queensland health service in 1995. By the end of 1999, there were more than 150 videoconferencing units in health facilities around the state. Six audits of videoconferencing usage were conducted using similar methodology at six-month intervals from November 1997 to May 2000. Between November 1997 and November 1999, the number of calls more than doubled, from 566 to 1378. Hours of usage almost trebled, from 671 to 1724. The average duration of calls remained similar, at about I h 12 min. The proportion of calls involving more than two sites (multipoint videoconferences) increased from 44% to 65%. The majority of the activity was for education (including training). Videoconferencing was also used for administration and clinical care. Mental health staff were the heaviest users, but use by health professionals from other specialty areas increased during the study period. The Queensland health service has realized a number of important benefits from telehealth.

Curriculum development for professional ethics in Australian human service university programmes

Australian academics and practitioners in the human services are particularly susceptible to social, political and economic influences in respect of their relevance, viability and operations. In fact, it can be argued that the impact of these influences has placed human service practitioners and academics in a perpetual state of vulnerability. Australian universities have been challenged to make their programmes more relevant and viable to the community at large, and practitioners face increasing workloads with limited resources based on restricted fiscal allocation, and the changing relationship between government and service providers. Drawing on interview data from twenty-one (n = 21) practitioners, this article highlights their identified problems regarding the notion of professionalism in the human services with a particular focus on ethical dilemmas in human service practice. Gleaning these details will be a basis for recommending necessary professionalethics curricula content in human services programmes offered in Australian universities. Moreover, while the research data is Australian based, the authors contend that the universal theories and principles underpinning human service practice justify the significance and value of the data as an important source for international consideration in curriculum development of human service academic programmes.

Credibility and staff conduct make or break bank customer service quality

Service quality is assessed by customers along the dimensions of staff conduct, credibility, communication, and access to teller services. Credibility and staff conduct emerge as the highest loading first-order factors. This highlights the significance of rectifying mistakes while keeping customers informed, and employing branch staff that are responsive and civilized in their conduct. Discovery of a valid second-order factor, namely, overall customer service quality, underscores the importance of providing quality service across all its dimensions. For example, if the bank fails to rectify mistakes and keep customers informed but excels in all other dimensions, its overall customer service quality can still be rated poorly.

Equity in regional service provision

Most transportation agencies stipulate that an important planning goal is to provide equitable and just public transport services. However, who is to be served and the type of service that should be provided has been ambiguous. This paper develops a methodology for examining equity in the provision of public transportation services. An approach for identifying areas in need of public transport is developed based upon the use of socio-demographic and economic information. Public transport need is then related to levels of access to service. This approach makes it possible to establish the degree to which public transport services may be considered equitable in relation to need and suitable access. A detailed analysis of the southeast Queensland region of Australia illustrates how this approach may be used to inform public transport decision making.

Service guarantees: A strategic mechanism to minimise customers' perceived risk in service organisations

Service offerings are largely intangible in nature. Customers are thus unable to assess the purchase outcome prior to experience, rendering the risk of possible customer dissatisfaction very high. It is argued that the concept of service guarantees proposed by services management theory can be effectively utilised to reduce the perceived risk of dissatisfaction for the customer in service organisations. Additionally, it is suggested that service guarantees force management to undertake activities which elevate the superiority of the organisation in the eyes of the customer and, thus, the opportunity to transform one-time customers into loyal ones. The purpose of this paper is twofold: first, to illustrate how customers’ behavioural intentions can be influenced by the use of a service guarantee; and second, to outline a systematic process that can help service business managers to develop and implement an effective service guarantee. This research highlights the numerous benefits available to service organisations by utilising the service guarantee as a strategic tool. Some of the important management implications are also outlined.

Congenital thyrotoxicosis in premature infants

OBJECTIVES Graves' disease (GD) complicates 0.1% to 0.2% of pregnancies, but congenital thyrotoxicosis is rare occurring in one in 70 of these pregnancies independent of maternal disease status. Antenatal prediction of affected infants is imprecise; however, maternal history, coupled with a high maternal serum TSH receptor binding immunoglobulin index (TBII) predict adverse neonatal outcome. Mortality is reported to be as high as 25% in affected infants and would therefore be expected to be higher in premature infants. This study illustrates that in sick, premature, extreme low birth weight (ELBW) or intrauterine growth retarded (IUGR) infants, the diagnosis maybe overlooked especially in the absence of antenatal risk assessment and management of thyrotoxicosis in this setting is complex. DESIGN and PATIENTS The records of premature neonates born at the three main maternity units in Brisbane, between January 1996 and July 1998 diagnosed with congenital thyrotoxicosis were reviewed. Data were recorded on gestational age, birth weight (B Wt), maternal thyroid history and current status, and neonatal course. Thyroid function and TBII status was assessed using standard biochemical assays. RESULTS Seven neonates from five pregnancies were identified (four female, three male). Mean gestational age was 30 week (25-36 week) and median B Wt was 1.96 kg (0.50-2.62 kg). Only one mother received formal antenatal counselling by a paediatric endocrine service and had a TBII (54%) measured prior to delivery. Three of five mothers had elevated TBII measured after diagnosis in their offspring (57%, 65%, 83%) and in one mother, a TBII was not performed. All mothers were biochemically euthyroid at delivery. Mean age at diagnosis was 9 days (1-16 days) and mean age at commencement of treatment was 12 days (7-26 days). Two infants received propylthiouracil and five received a combination of carbimazole and propranolol. Pour became biochemically hypothyroid, in three this resolved with cessation of the antithyroid drug (ATD), and one required ongoing T4 supplementation. Only one infant required treatment for cardiac failure and there were no deaths in this cohort. CONCLUSIONS This is a large series of extremely small and premature infants with neonatal thyrotoxicosis. Presentation was nonspecific. The diagnosis was delayed because of low birth weight, prematurity, multiple birth and/or an unrecognized maternal history of Graves' disease. The treatment of neonatal thyrotoxicosis was difficult in these extreme law birth weight infants yet no infant died and significant morbidity was confined to high output cardiac failure in one infant. With antenatal recognition of past or active Graves' disease, assessment of maternal TSH receptor binding immunoglobulin index prior to delivery and postnatal monitoring of cord TSH and venous fT4 and TSH on days 4 and 7 rapid treatment of affected infants may have further reduced neonatal morbidity.

Service quality and consumers' experience: Towards an interpretive approach

As marketers and researchers we understand quality from the consumer's perspective, and throughout contemporary service quality literature there is an emphasis on what the consumer is looking for, or at least that is the intention. Through examining the underlying assumptions of dominant service quality theories, an implicit dualistic ontology is highlighted (where subject and object are considered independent) and argued to effectively negate the said necessary consumer orientation. This fundamental assumption is discussed, as are the implications, following a critical review of dominant service quality models. Consequently, we propose an alternative approach to service quality research that aims towards a more genuine understanding of the consumer's perspective on quality experienced within a service context. Essentially, contemporary service quality research is suggested to be limited in its inherent third-person perspective and the interpretive, specifically phenomenographic, approach put forward here is suggested as a means of achieving a first-person perspective on service quality.

Cash, customers, and care: The experience and meaning of differential payment for high care places in aged care facilities

The introduction of new asset/income tested charges for high care residents was the 1997-98 Commonwealth government policy response to concerns about financing residential aged care. This in-depth study of residents, families, staff and managers in three aged care facilities explores issues of equity, access and empowerment arising when some residents pay more for the same level of care and amenity. The study reports little evidence of financial contributions affecting access to high care places and the delivery of care, the potential for differential access to amenities such as single rooms linked to the extra payments, and no evidence of a sense of empowerment linked to payment of the new charges. The complexity of current financial arrangements, access to appropriate financial advice at the time of entry, and the potential for an informal two tier system in relation to the allocation Of amenities are identified as developing policy issues.
