Early empirical studies of exchange rate determinants demonstrated that fundamentals-based monetary models were unable to outperform the benchmark random walk model in out-of-sample forecasts while later papers found evidence in favor of long-run exchange rate predictability. More recent theoretical works have adopted a microeconomic structure; a utility-based new open economy macroeconomic framework and a rational expectations present value model. Some recent empirical work argues that if the models are adjusted for parameter instability, it is a good predictor of nominal exchange rates while others use aggregate idiosyncratic volatility to generate good predictions. This latest research supports the idea that fundamental economic variables are likely to influence exchange rates especially in the long run and further that the emphasis should change to the economic value or utility based value to assess these macroeconomic models.

Understanding how agents formulate their expectations about Fed behavior is important for market participants because they can potentially use this information to make more accurate estimates of stock and bond prices. Although it is commonly assumed that agents learn over time, there is scant empirical evidence in support of this assumption. Thus, in this paper we test if the forecast of the three month T-bill rate in the Survey of Professional Forecasters (SPF) is consistent with least squares learning when there are discrete shifts in monetary policy. We first derive the mean, variance and autocovariances of the forecast errors from a recursive least squares learning algorithm when there are breaks in the structure of the model. We then apply the Bai and Perron (1998) test for structural change to a forecasting model for the three month T-bill rate in order to identify changes in monetary policy. Having identified the policy regimes, we then estimate the implied biases in the interest rate forecasts within each regime. We find that when the forecast errors from the SPF are corrected for the biases due to shifts in policy, the forecasts are consistent with least squares learning. © 2014 Elsevier B.V.

This article deals with two concerns in achieving greater accountability in social reports: the lack of completeness of reporting, and the lack of credibility of reports. The article focuses, in particular, on the role of social audits in improving the completeness and credibility of reporting, thereby reducing the audit expectations gap. We suggest that this gap arises due to an over-emphasis on the validity of performance data at the expense of addressing completeness and credibility, both of which, we argue, require stakeholder involvement. The article reviews recent guidelines aimed at ensuring that companies produce reports that are complete in all material respects including those produced by the Global Reporting Initiative and the Federation des Experts Comptables Europeens, focusing particularly on AccountAbility's AA1000 Standard and AA1000S Assurance Standard. Finally, the article considers the development of a practical approach to social audit following principles increasingly being incorporated into developing assurance guidelines aimed at reducing the audit expectations gap.

Objectives:  The first objective of this study was to identify the knowledge, skills and attributes (KSAs) that employers seek in newly graduated dietitians. The second objective was to compare the KSAs that employers seek in newly graduated dietitians to the Deakin University Graduate Attributes and to the Dieticians Association of Australia (DAA) Competencies in order to determine if there is a mismatch.

Methods:   Views were gathered from a combination of group and individual in-depth, semistructured interviews with 19 employers from a range of employment settings and sorted into an existing framework using the DAA Competencies and the Deakin University Graduate Attributes. Data from taped interviews were transcribed and sorted into a table of generic skills and a KSAs matrix.

Results
: Employers sought graduates who had practical knowledge of dietetics and the workplace, Key skills sought included communication, interpersonal, work management and information technology skills. Key attributes sought were the ability to be a team player, to demonstrate some insight into one's own limitations, to demonstrate an appropriate level of initiative, and to be flexible and adaptable. There was a large overlap between the KSAs identified by employers as being important and those that have been identified by the DAA and Deakin University. However, there were some areas of mismatch. The University and employers valued information technological skills, whereas the DAA did not state these as a competency. The University and the industry employers were concerned about the global perspective, but the DAA and the clinical employers were not.

Conclusions: The results of this study show a large overlap between the KSAs valued by the profession, the University and the employers.

In contrast to other studies of students in online environments, which examine the skills and attitudes that students bring to an online university learning environment, we are interested in the expectations with which students come to online university study. Four expectational barriers, which arise from students’ background and cultural history, are identified as being: who is responsible for learning, who is responsible for student interaction with content, who is responsible for the use of appropriate learning strategies and who is responsible for required ancillary skills. There is a discussion of how these barriers arise and how one might attempt to manage the students’ expectations and ameliorate their effects.

Developing relevant and innovative University courses is a complex and often difficult task. This is particularly true when developing environmental science courses as the banner of environmental science has the potential to include an extremely vast array of subject material and course content. Added to this is the diversity of students entering these courses, and their associated course expectations and aspirations. A third component that cannot be ignored when developing courses includes employer demands and expectations of graduates at course completion. As tertiary educators we therefore have the challenge of developing innovative environmental science courses that are academically challenging, but meet the expectations of students, staff and potential future employers. To ensure that we meet this challenge it is vital that we determine the expectations of all relevant parties (students, staff, and potential employers) and develop our courses accordingly.  Here we report on the 'student expectations' component of this. To determine student expectations we conducted a survey of all commencing first year environmental science students. The survey asked students to provide information on drivers for course selection, preferred learning styles, the importance of different approaches to teaching, subject interest areas and employment aspirations. Our results found that environmental science students have a preference for fieldwork and hands-on experience and are very supportive of teaching that combines different teaching methods. On-line teaching was not supported by commencing environmental science students. Commencing students showed a very strong interest in key subject areas of environmental science such as Wildlife, animal conservation, national and marine parks, conservation and marine Wildlife; however, some of the critical areas of environmental science such as population statistics, social sciences and chemistry did not attract the same level of interest. Most commencing students had some idea on where they would like to gain employment on course completion. Knowledge relating to student expectations is Vital, particularly when designing courses, developing specific unit content and undertaking marketing and course information sessions. With this knowledge we can be confident that students enrolling in environmental science will, to a large extent, have their expectations met.

Until recently, the author was in Scotland, where professional registration in social work extends to students and involves criminal record checks prior to acceptance into a course of study. She is now teaching at Deakin University in Australia, which places a high priority on making higher education available to persons and groups who have traditionally been excluded, both through the provision of courses through off campus (distance education) study mode and an innovative and culturally sensitive mode of provision for indigenous Australians. One result of our attempts to redress social exclusion is that, on occasion, we discover that some of our students are incarcerated. There are important logistical issues which may emerge as a consequence of accepting prisoners into a program of social work education. However, it would seem that the inclusion of prisoners is symbolic of a fundamental difference in philosophy with programmes of social work education in countries where there is a strong expectation that social work educators act as gatekeepers to the profession, especially in respect of students with criminal convictions. This in tum reflects an expectation among social work educators in Australia that it may be more appropriate for professional associations or registration bodies to determine whether or not a graduate with a criminal record is suitable for employment as a professional social worker. In some settings, a prior criminal record is not a barrier to being an effective service provider, as well as international differences in understandings of the social work role and employment
destinations of social work graduates.

Research consistently demonstrates the strategic benefits of providing quality in service delivery (Tse and Wilton 1988; Anderson and Zeithaml 1984). However, to deliver a quality service, it is first necessary to determine the level of quality expectations that consumers have for a particular service industry. This paper examines whether quality expectations vary across services based on their degree of total intangibility. A controlled, repeated measures design is utilised, whereby subjects are each asked to evaluate three services that vary in their degree of intangibility. Contrary to past findings, results indicate that consumer expectations for service quality do not vary with the level of intangibility of the service.

This paper focuses on the continuing worldwide phenomenon of homogenisation of audit rules, regulation and procedures between the government and private sectors. The observations are informed by Pusey’s (1991) criticisms of ‘economic rationalism’ as the driving mechanism behind public sector reforms in Australia. The presumed superiority of commercial audit is questioned in association with the work of Hopwood (1983, 1998), Otley and Pierce (1996) and, Power (1992, 1994, 1995, 1996, 1997) that contextualise the role of audit. In the private sector audit there continues to be an ‘expectations gap’ arising from commercial pressures and a rhetorical support for the public interest. It is contended that audit quality in the public sector is driven by a different perception of public interest that has been eroded with the advent of economic rationalism. The consequent emergence of a public sector audit ‘expectations gap’ is an amalgam of new components particular to the government audit environment and, aspects of the private ‘expectations gap’ which have been transplanted into the public domain.

While research has focussed on the current and potential role of the practice nurse (PN) in Australia, the acceptability of this role by consumers has not been investigated. In 2002, two independent studies were carried out into consumer perceptions of PNs. A discussion between the two groups of researchers at the inaugural National Practice Nurse Conference in 2003, identified significant similarities in the findings of these studies. This article reports the combined findings as they relate to consumers' desire for access to the health practitioner of their choice, and their concern that PNs may assume a gatekeeping role. These perceptions may have significant impact on the acceptance of PNs across Australia.

We have entered the age of the contingent or temporary worker, the consultant and the subcontractor. Workers are expected to be pliable and tractable; to “fit in.” Being made redundant is also an area where modern workers are expected to be flexible and resilient. However, when these so-called “flexible” workers are told their job no longer exists, the accompanying sense of rejection and alienation can be excruciating. Stories of being made redundant were collected during an exploratory, qualitative study, using Heideggerian phenomenology as the methodological vehicle to capture the lived experiences of those affected. Focused, in-depth interviews were conducted with the ten respondents; nine men and one woman. The stories shared suggest that being made redundant is an alienating experience with respondents sharing feelings of powerlessness, shock, betrayal, shame and social isolation. Unfortunately, those having experienced redundancy were also not as resilient as is routinely assumed. They did not “bounce back” unchanged, but reported significant negative outcomes including fear for the future, underemployment, family disruptions and an erosion of trust. Recommendations are made orienting organisations towards a more human process of redundancy.

The "babyboomer" generation, those who were born between 1946 and 1965, account for over 30% of the population in Australia, and it is no surprise that the government is concerned about the financial implications for future healthcare costs. While many babyboomers are more financially secure than previous generations have been on account of compulsory superannuation contributions made over the past 15 years, there are still some who are financially vulnerable and expect to rely on government pensions and welfare assistance. Changes to family structures and job security also mean that those who are less financially secure will need social support. Using an ecological framework model , we explored the retirement expectations and experiences of some Australian babyboomers through focus groups and individual interviews to identify key issues and their plans to address these issues. Four main themes are reported in this paper: retirement attitudes and expectations, finances, health, and food. The results suggested that for many persons retirement equated freedom. Little future planning was undertaken for retirement other than contributing to superannuation schemes, and expectations were reported in general terms, such as wanting to remain independent and healthy and to have time to socialize and travel.
