Collaborative creativity in requirements engineering: analysis and practical advice

Requirements engineering (RE) often entails interdisciplinary groups of people working together to find novel and valuable solutions to a complex design problem. In such situations RE requires creativity in a form where interactions among stakeholders are particularly important: collaborative creativity. However, few studies have explicitly concentrated on understanding collaborative creativity in RE, resulting in limited advice for practitioners on how to support this aspect of RE. This paper provides a framework of factors characterising collaborative creative processes in RE. These factors enable a systematic investigation of the collaboratively creative nature of RE. They can potentially guide practitioners when facilitating RE efforts, and also provide researchers with ideas on where to focus when developing methods and tools for RE. © 2013 IEEE.

Literature, museums, and national identity; or, why are there so many writers' house museums in Britain?

Writers’ houses constitute the largest and oldest segment of historic house museums dedicated to famous persons in the United Kingdom. Litterateurs tend to ascribe ‘lit houses’ to the ineffable magic of readers’ connections to writers. By contrast, my analysis deploys the analytic of cultural politics to suggest that writers’ house museums can more fully be understood as assertions of national identity. The elision of language with national distinction is subliminal in everyday life, but can be brought to prominence by historicising the nations of the British Isles, and the practice of writing in English.

Association between participation in outpatient cardiac rehabilitation and self-reported receipt of lifestyle advice from a healthcare provider: results of a population-based cross-sectional survey

We test the hypothesis that the odds of self-reported receipt of lifestyle advice from a health care provider will be lower among outpatient cardiac rehabilitation (OCR) nonattendees and nonreferred patients compared to OCR attendees. Logistic regression was used to analyse cross-sectional data provided by 65% (4971/7678) of patients aged 20 to 84 years discharged from public hospitals with a diagnosis indicating eligibility for OCR between 2002 and 2007. Among respondents, 71% (3518) and 55% (2724) recalled advice regarding physical activity and diet, respectively, while 88% (592/674) of smokers recalled quit advice. OCR attendance was low: 36% (1764) of respondents reported attending OCR, 11% (552) did not attend following referral, and 45% (2217) did not recall being invited. The odds of recalling advice regarding physical activity and diet were significantly lower among OCR nonattendees compared to attendees (OR 0.34, 95% CI 0.21, 0.56 and OR 0.33, 95% CI 0.25, 0.44, resp.) and among nonreferred respondents compared to OCR attendees (OR 0.10, 95% CI 0.07, 0.15 and OR 0.17, 95% CI 0.14, 0.22, resp.). Patients hospitalised for coronary heart disease should be referred to OCR or a suitable alternative to improve recall of lifestyle advice that will reduce the risk of further coronary events.

Maternal dietary intake and physical activity habits during the postpartum period: associations with clinician advice in a sample of Australian first time mothers

BACKGROUND: Numerous health benefits are associated with achieving optimal diet and physical activity behaviours during and after pregnancy. Understanding predictors of these behaviours is an important public health consideration, yet little is known regarding associations between clinician advice and diet and physical activity behaviours in postpartum women. The aims of this study were to compare the frequency of dietary and physical activity advice provided by clinicians during and after pregnancy and assess if this advice is associated with postpartum diet and physical activity behaviours.

METHODS: First time mothers (n = 448) enrolled in the Melbourne InFANT Extend trial completed the Cancer Council of Australia's Food Frequency Questionnaire when they were three to four months postpartum, which assessed usual fruit and vegetable intake (serves/day). Total physical activity time, time spent walking and time in both moderate and vigorous activity for the previous week (min/week) were assessed using the Active Australia Survey. Advice received during and following pregnancy were assessed by separate survey items, which asked whether a healthcare practitioner had discussed eating a healthy diet and being physically active. Linear and logistic regression assessed associations of advice with dietary intake and physical activity.

RESULTS: In total, 8.6 % of women met guidelines for combined fruit and vegetable intake. Overall, mean total physical activity time was 350.9 ± 281.1 min/week. Time spent walking (251.97 ± 196.78 min/week), was greater than time spent in moderate (36.68 ± 88.58 min/week) or vigorous activity (61.74 ± 109.96 min/week) and 63.2 % of women were meeting physical activity recommendations. The majority of women reported they received advice regarding healthy eating (87.1 %) and physical activity (82.8 %) during pregnancy. Fewer women reported receiving healthy eating (47.5 %) and physical activity (51.9 %) advice by three months postpartum. There was no significant association found between provision of dietary and/or physical activity advice, and mother's dietary intakes or physical activity levels.

CONCLUSIONS: Healthy diet and physical activity advice was received less after pregnancy than during pregnancy yet no association between receipt of advice and behaviour was observed. More intensive approaches than provision of advice may be required to promote healthy diet and physical activity behaviours in new mothers.

The provision of business advice to SMEs by external accountants

Purpose – Business advisory services are an emerging service category for external accountants in the small and medium-sized enterprise (SME) environment. The purpose of this study is to investigate determinants of SME demand for business advice, drawing on the agency theory, relational marketing and resource-based literatures.

Design/methodology/approach – The study empirically tested theoretical predictions based on an Australia-wide survey of SMEs, in which 485 firms responded to a questionnaire.

Findings – The results show that the purchase of business advice is significantly and positively associated with the perceived competence of the external accountant, but significantly and negatively associated with length of the relationship. However, the authors observe a significant positive interaction between tenure of the relationship and competence. A unique contribution of this study is the development of the understanding of the combined role of the external accountant’s competence and the tenure of the relationship. The findings indicate that SMEs require time to verify whether accountants have the competence to provide business advice, suggesting that information asymmetry and uncertainty is minimised only after SMEs have nurtured relationships with their external accountants, and after they have developed some confidence in the competence of their external accountants. At the same time, the negative association with tenure suggests that when accountants are not perceived as competent advisors, SMEs purchase less advice over time.

Research limitations/implications – The paper has important theoretical implications by augmenting agency theory, the relational marketing and the resource-based literature, and it clarifies which antecedent factors are important in explaining demand for business advisory services provided by accountants to their SME clients. In particular, the paper highlights the importance of the combined roles that the external accountant’s competence and tenure play in the SME–accountant relationship, highlighting how these two factors can overcome credence issues and ex ante information problems.

Practical implications – The findings have practical implications for government initiatives targeting support to SMEs, as the findings identify small firms and firms planning to grow as likely to gain the greatest benefit from external advice and support.

Originality/value – This study adds to the limited literature and scant theoretical discussions on the emergence of business advisory services that accountants provide to their SME clients by drawing on several theories to explain the determinants of business advice.

The effect of the apolipoprotein E genotype on response to personalized dietary advice intervention: findings from the Food4Me randomized controlled trial

BACKGROUND: The apolipoprotein E (APOE) risk allele (ɛ4) is associated with higher total cholesterol (TC), amplified response to saturated fatty acid (SFA) reduction, and increased cardiovascular disease. Although knowledge of gene risk may enhance dietary change, it is unclear whether ɛ4 carriers would benefit from gene-based personalized nutrition (PN). OBJECTIVES: The aims of this study were to 1) investigate interactions between APOE genotype and habitual dietary fat intake and modulations of fat intake on metabolic outcomes; 2) determine whether gene-based PN results in greater dietary change than do standard dietary advice (level 0) and nongene-based PN (levels 1-2); and 3) assess the impact of knowledge of APOE risk (risk: E4+, nonrisk: E4-) on dietary change after gene-based PN (level 3). DESIGN: Individuals (n = 1466) recruited into the Food4Me pan-European PN dietary intervention study were randomly assigned to 4 treatment arms and genotyped for APOE (rs429358 and rs7412). Diet and dried blood spot TC and ω-3 (n-3) index were determined at baseline and after a 6-mo intervention. Data were analyzed with the use of adjusted general linear models. RESULTS: Significantly higher TC concentrations were observed in E4+ participants than in E4- (P < 0.05). Although there were no significant differences in APOE response to gene-based PN (E4+ compared with E4-), both groups had a greater reduction in SFA (percentage of total energy) intake than at level 0 (mean ± SD: E4+, -0.72% ± 0.35% compared with -1.95% ± 0.45%, P = 0.035; E4-, -0.31% ± 0.20% compared with -1.68% ± 0.35%, P = 0.029). Gene-based PN was associated with a smaller reduction in SFA intake than in nongene-based PN (level 2) for E4- participants (-1.68% ± 0.35% compared with -2.56% ± 0.27%, P = 0.025). CONCLUSIONS: The APOE ɛ4 allele was associated with higher TC. Although gene-based PN targeted to APOE was more effective in reducing SFA intake than standard dietary advice, there was no difference between APOE "risk" and "nonrisk" groups. Furthermore, disclosure of APOE nonrisk may have weakened dietary response to PN. This trial was registered at clinicaltrials.gov as NCT01530139.
