Perceptions of quality in higher education : a comparative study of Turkish and Australian business academics

Finding a common definition of ‘quality’ in studies of quality and quality improvement in higher education institutions is very important. This study identifies the views of a key stakeholder group, academics, with reference to their beliefs (what is currently occurring) and their attitudes (what ought to be occurring) in relation to quality in their departments. The focus of this paper is on the collection of data from 64 business administration academics in Turkish universities. Face-to-face interviews were conducted using an instrument titled ‘Quality in Accounting Education Survey’. The questionnaire was developed by Watty and is based on the conceptions of quality framework, developed by Harvey and Green. The results are compared with the beliefs and attitudes of Australian accounting academics as reported in an earlier paper by Watty. The findings show that academics from Turkey adopt the perspective of quality as excellent or élitist, both in their beliefs (current situation perception) and in their attitudes (desired situation perception). This compares with the findings that Australian academics’ attitudes reflect a quality perspective as fitness for purpose in the current situation and beliefs that reflect a transformational quality perspective as the desired situation (what ought to be).

Inflation and quality dispersion

One questionable aspect of price posting with directed search is the strong commitment by sellers to commit to the advertised terms of trade. In this paper I explore the welfare implications of assuming that sellers cannot commit and vary the quality of their output ex post according to realized demand. I show that such lack of commitment translates into lower participation by buyers, lower average quality, and a consumption-equivalent loss of 0.3% of annual GDP.

Lifetime and fleece quality traits associated with the occurrence of entangled mohair staples

Staple entanglement in mohair fleeces occurs when adhesions form between longer and faster growing fibres and shorter and slower growing fibres. This results in accentuated crimp of the longer fibres and an "apparently" reduced staple length. The appearance in the fleece of Angora goats of staple entanglements can lead to the downgrading of the mohair to poorer style and shorter length grades, resulting in up to 60% price reductions. This study examined how staple entanglement score (SES) is related to lifetime factors of Angora goats, and how this relationship can be explained by variations in animal size and fleece attributes. SES was scored using a five-point scale: 5, long free fibres easily separated as no adhesions; 4, some adhesions between fibres; 3, some effort to separate fibres as many adhesions; 2, many adhesions, staple fibres entangled, shortening of staple; 1, very entangled and shortened staple. Measurements were made over 9 shearing periods on a population of Angora castrated males (wethers) goats representing the current range and diversity of genetic origins in Australia, including South African, Texan and interbred admixtures of these and Australian sources. Data on genetic origin, sire, dam, date of birth, dam age, birth weight, birth parity, weaning weight, live weight, fleece growth and fleece attributes were recorded. Two restricted maximum likelihood (REML) models were developed to relate SES with age, animal lifetime factors, fleece quality attributes and live weight. One model allowed fleece quality and live weight traits in the model and the other excluded these traits. Staple entanglement was almost eliminated in mohair harvested from goats shorn every 3. months but was common in mohair from goats shorn twice or once per year. SES was less in goats of Texan genetic background, and was generally less in winter grown mohair. SES was higher for mohair with low fibre curvature (FC, 10°/mm) and a high clean washing yield (CWY, 90%) compared with mohair with low FC and lower CWY (80%), and compared with all mohair with high FC (18°/mm). The response of SES to shearing regime, genetic background, shearing season, age of goat and a response to dam age were almost identical whether or not an adjustment was made for CWY and FC. There was a moderate amount of variability due to sires and individuals. We can conclude that a large part of these effects observed, namely breed, dam age, sire, and a component of the FC and CWY effects, are genetic. Mohair producers can manage the genetic effects by careful selection of sires, especially avoiding those with low CWY or high FC, and avoiding sires with higher levels of staple entanglement or that have produced progeny with higher levels of staple entanglement. Also, unidentified environmental effects are affecting staple entanglement, although a lack of a live weight change effect on entanglement indicates that this effect might not be due to nutrition. © 2013 Elsevier B.V.

Evaluating irradiation dose for sterility induction and quality control of mass-produced fruit fly Bactrocera tryoni (Diptera : Tephritidae)

The sterile insect technique has been routinely used to eradicate fruit fly Bactrocera tryoni (Froggatt) incursions. This study considers whether fly quality in a mass-rearing facility can be improved by reducing irradiation doses, without sacrificing reproductive sterility. Pupae were exposed to one of five target irradiation dose ranges: 0, 40-45, 50-55, 60-65, and 70-75 Gy. Pupae were then assessed using routine quality control measures: flight ability, sex ratio, longevity under nutritional stress, emergence, and reproductive sterility. Irradiation did not have a significant effect on flight ability or sex ratio tests. Longevity under nutritional stress was significantly increased at 70-75 Gy, but no other doses differed from 0 Gy. Emergence was slightly reduced in the 50-55, 60-65, and 70-75 Gy treatments, but 40-45 Gy treatments did not differ from 0 Gy, though confounding temporal factors complicate interpretation. Reproductive sterility remained acceptable (> 99.5%) for all doses--40-45 Gy (99.78%), 50-55 Gy (100%), 60-65 Gy (100%), and 70-75 Gy (99.99%). We recommend that B. tryoni used in sterile insect technique releases be irradiated at a target dose of 50-55 Gy, providing improved quality and undiminished sterility in comparison with the current 70-75 Gy standard while also providing a substantial buffer against risk of under dosing.

Self-reported access to and quality of healthcare for diabetes : Do the severely obese experience equal access?

Background: Given reported pejorative views that health professionals have about patients who are severely obese, we examined the self-reported views of the quality and availability of diabetes care from the perspective of adults with type 2 diabetes (T2DM), stratified by body mass index (BMI). Methods: 1795 respondents to the Diabetes MILES - Australia national survey had T2DM. Of these, 530 (30%) were severely obese (BMI ≥35 kg/m2) and these participants were matched with 530 controls (BMI <35 kg/m2). Data regarding participants' self-reported interactions with health practitioners and services were compared. Results: Over 70% of participants reported that their general practitioner was the professional they relied on most for diabetes care. There were no betweengroup differences in patient-reported availability of health services, quality of interaction with health practitioners, resources and support for selfmanagement, or access to almost all diabetes services. Discussion: Participants who were severely obese did not generally report greater difficulty in accessing diabetes care.

Revisiting the relationship between marriage and wellbeing : does marriage quality matter?

This paper revisits the marriage and wellbeing relationship using variables reflecting marriage quality and data from the US, the UK and Germany. People in self-assessed poor marriages are fairly miserable and much less happy than unmarried people, even in the first year of marriages. However, people in self-assessed good marriages are even happier than the literature suggests. Women show greater range of responses to marriage quality than men. The effect of employment status and subjective health on happiness and the marriage effects on interpersonal trust and mental health change dramatically when marriage quality is controlled for. A strong link from happiness to marriage does not exist. However, happier people are more likely to stay single instead of being unhappily married, but less likely to stay single compared to being very happily married and happiness cannot predict staying single versus being pretty happily married.

Use of airflow to improve the nanofibrous structure and quality of nanofibers from needleless electrospinning

Mass production of nanofibers from needleless electrospinning shows great potential in research and development of nanofibers. However, how to improve the electrospinning performance so as to achieve high quality nanofibers is still of great challenge. In this study, airflow has been applied to optimize upward needleless electrospinning from ring spinneret. Effects of airflow speed and the position of airflow on the nanofiber quality and production rate have been investigated. It has been found that thinner and more uniform nanofibers were produced when airflow was applied to needleless electrospinning system. It also improved the collected nonwoven membrane, resulting in better nanofibrous structure of the as-spun nanofibers. Application of airflow on needleless electrospinning would further benefit the development of mass production of nanofibers from needleless electrospinning.

Auditor industry specialization, political economy and earnings quality: some cross-country evidence

Using cross-country data, we evaluate the impact of investor protection on the association between earnings quality and audits by industry specialists. Our findings show that the positive association between industry specialist auditors and earnings quality as documented in the literature is affected by the political electoral system, which reflects investor protection rights in a country. We document that audits by industry specialists are associated with higher earnings quality in countries with the proportional electoral system, reflecting weak investor protection. Our results also confirm Kwon et al.'s findings that overall there is a positive association between earnings quality and audits by industry specialists in countries with weak legal enforcement. Our findings, however, indicate that Kwon et al.'s results are valid only for countries with weak investor protection reflected by the proportional electoral system and not for countries with strong investor protection reflected by the majoritarian electoral system. These findings thus suggest that higher earnings quality of firms audited by industry specialists across countries can especially be expected when investor protection is low and legal enforcement is also weak. In addition, our research suggests that future cross-country studies could explicitly consider the role of the political electoral system of a country in evaluating corporate governance, management and accounting issues.

State-owned enterprises, competition and product quality

We consider a general oligopoly model with consumer surplus moderated quantity competition among state-owned enterprises (SOEs), where the SOEs employ workers who are members of the state-owned worker union and produce differentiated products. We show that increasing the number of SOEs would lead to an outcome in which these enterprises choose a lower level of product quality and this, in turn, results in welfare losses for the society, depending on the degree of substitutability. Our findings are consistent with the evidence from China and uncovers important linkages that exist between worker union, product quality and competition, and that have mostly been ignored in the industrial organisation, trade and development literature.

Relationships between civil engineering students’ learning approaches and their perception of curriculum and teaching quality

BACKGROUND: Deakin University graduated its first cohort from four-year undergraduate civil engineering course/program in 2012. The internal annual Course Experience Survey, which has been running annually since 2012, targets to identify the graduating students’ learning approaches and students’ perceptions of the curriculum and teaching quality. Literature suggests that students’ learning outcomes can be achieved more efficiently when the students’ perceptions of curriculum and teaching quality are closely aligned with their learning approaches. Where the students’ approaches to learning and their perception of curriculum and teaching quality are mismatched, a series of frustrations can result for the students that may not only negatively impact their learning achievement but also their learning experience.
PURPOSE OR GOAL: This study explores the relationships between students’ learning approaches and their perception of curriculum and teaching quality in an undergraduate civil engineering program/course. This will help understand whether the curriculum and teaching quality provided by the university have actually accommodated ‘all’ enrolled students in the similar way.
APPROACH: To uncover these relationships, this study adopts questionnaire survey approach to collect response data over a two year period by asking students about their perception through a series of statements. 5-point Likert-scale questionnaire survey (strongly disagree, disagree, neutral, agree, strongly agree) is developed and responses are collected. The responses are then statistically analysed in order to uncover the relationships between students’ learning approaches and their perception of curriculum and teaching quality provided by the university.
DISCUSSION: Deep learners and surface learners had a statistically different perception of curriculum and teaching quality. These results contradict the assumption that learners will have uniform preferences on the curriculum, teaching quality and the way they deal with the demands of specific learning situations. Anecdotal belief that ‘good course/program curriculum and good teaching approaches are good for all students and vice-versa’ may not be strictly true for contemporary heterogeneous student cohorts.
RECOMMENDATIONS/IMPLICATIONS/CONCLUSION: This finding highlights the challenge for curriculum designer to design appropriate course curriculum and teaching staff to implement efficient teaching strategies that benefit both surface and deep learners, who are usually enrolled together. It may be beneficial to provide diversity and flexibility in the curriculum and teaching approaches (rather than a uniform approach). However, this may demand additional resources and may also be questioned for equity and consistency of education. It is also important to note that due to relatively a small dataset, these results may not be generalised.

Diet quality is associated with obesity and hypertension in Australian adults: a cross sectional study.

BACKGROUND: Poor diet, characterized by a low diet quality score, has been associated with greater prevelence of obesity and hypertension. However, the evidence is inconsistent across diet quality scores and by sex. The aim was to investigate the relationship between diet quality and obesity and hypertension. METHODS: Adults (n = 4908; age 45.2 ± 0.24 years) were included from the cross-sectional Australian Health Survey 2011-2013. Two 24-h dietary recalls were used to derive the dietary guideline index (DGI) and recommended food score (RFS). Logistic regression investigated relationships between diet quality score and odds ratio of obesity, hypertension and obesity-associated hypertension. RESULTS: In the highest tertile of DGI, but not RFS, individuals were less likely to be obese (men: OR 0.64, CI: 0.45, 0.92, P-trend = 0.014; women: 0.68, 0.48, 0.96, P-trend = 0.025) and to have central adiposity (men: 0.68, 0.48, 0.97, P-trend = 0.030; women: 0.53, 0.37, 0.77, P-trend = 0.001) compared with the lowest tertile. Men, but not women, in the highest tertile of DGI and RFS were less likely to be hypertensive (DGI: 0.56, 0.37, 0.85, P-trend = 0.006; RFS: 0.62, 0.41, 0.94, P-trend = 0.021) compared with the lowest tertile. In men with obesity, but not normal weight men or women, those in the highest tertile of DGI were less likely to be hypertensive (0.53, 0.36, 0.78, P-trend = 0.001) compared with the highest tertile. CONCLUSIONS: Higher diet quality, as estimated using DGI, was associated with lower odds ratio of obesity in men and women. Odds ratio of hypertension was lower in men, but not women, with a high diet quality score compared with a low score, while obesity-associated hypertension was only associated with diet quality score in men with obesity. Longitudinal studies are needed to evaluate whether diet quality predicts risk of obesity and hypertension.

Wine prices and quality eatings: a meta-regression analysis

This article examines the empirical support for the hypothesized hedonic theoretical relation between the price of wine and its quality. The examination considers over 180 hedonic wine price models developed over 20 years, covering many countries. The research identifies that the relation between the price of wine and its sensory quality rating is a moderate partial correlation of +0.30. This correlation exists despite the lack of information held by consumers about a wine’s quality and the inconsistency of expert tasters when evaluating wines. The results identify a moderate price-quality correlation, which suggests the existence of strategic buying opportunities for better informed consumers. Strategic price setting possibilities may also exist for wine producers given the incomplete quality information held by consumers. The results from the meta-regression analysis point to the absence of any publication bias, and attribute the observed asymmetry in estimates to study heterogeneity. The analysis suggests the observed heterogeneity is explained by the importance of a wine’s reputation, the use of the 100-point quality rating scale, the analysis of a single wine variety/style, and the employed functional form. The most important implication from the analysis is the relative importance of a wine’s reputation over its sensory quality, inferring that producers need to sustain the sensory quality of a wine over time to extract appropriate returns. The reputation of the wine producer is found not to influence the strength of the price quality relationship. This finding does not contradict the importance of wine producer reputation in directly influencing prices.
