Effect of sorghum flour addition on in vitro starch digestibility, cooking quality and consumer acceptability of durum wheat pasta

Whole grain sorghum is a valuable source of resistant starch and polyphenolic antioxidants and its addition into staple food like pasta may reduce the starch digestibility. However, incorporating nondurum wheat materials into pasta provides a challenge in terms of maintaining cooking quality and consumer acceptability. Pasta was prepared from 100% durum wheat semolina (DWS) as control or by replacing DWS with either wholegrain red sorghum flour (RSF) or white sorghum flour (WSF) each at 20%, 30%, and 40% incorporation levels, following a laboratory-scale procedure. Pasta samples were evaluated for proximate composition, in vitro starch digestibility, cooking quality, and consumer acceptability. The addition of both RSF and WSF lowered the extent of in vitro starch digestion at all substitution levels compared to the control pasta. The rapidly digestible starch was lowered in all the sorghum-containing pastas compared to the control pasta. Neither RSF or WSF addition affected the pasta quality attributes (water absorption, swelling index, dry matter, adhesiveness, cohesiveness, and springiness), except color and hardness which were negatively affected. Consumer sensory results indicated that pasta samples containing 20% and 30% RSF or WSF had acceptable palatability based on meeting one or both of the preset acceptability criteria. It is concluded that the addition of wholegrain sorghum flour to pasta at 30% incorporation level is possible to reduce starch digestibility, while maintaining adequate cooking quality and consumer acceptability.

An issues paper: the roots/routes of Australian architecture: elements of an alternative architectural history

The dynamism and mobility of architects in their approach to architecturaldesign practice provides a context that emphasises that architecture, likeculture, is not static or rooted in place, but is intricately configured throughthe dual processes of locality and mobility – both physical and theoretical. Theproduction of architecture in Australia, as in other immigrant-rich societies,provides a case for reinforcing the theory that architectural mobility and travelare integral to the architecture of place.This issues paper sets out to re-examine the contribution of geo-culturalinfluences upon Australia’s architectural lineage and considers a diverse rangeof themes across an equally broad timeframe; British colonial transpositions; thedissemination of Modernism in Australia; the latent contribution of mid-twentiethcentury European émigré architects; and the secreted history of Australia’sAsian architecture. Common to all, however, is the notion of architecturaltranslation as a process of influences transmitted, transposed or adapted toother contexts. It uses Australia as the focus from which to consider how globalcriticism, ideas and theories have travelled and continue to travel transverselyacross time and place, from the late-eighteenth century well into the twenty-first.This paper investigates translations through narratives, processes, networks andtraces of architectural manifestations and begins to draw lines of influence.

Who cooks from scratch and how do they prepare food

Purpose – There is increasing interest in the domestic preparation of food and with the postulated health benefits of “cooking from scratch”. The purpose of this paper is to examine the demographic and food preparation associations of this term in order to examine its operational value. Design/methodology/approach – A national online survey was conducted during 2012 in Australia among 1,023 domestic food providers, half of whom were men. Questions were asked about cooking from scratch, demographic characteristics, food preparation practices and interest in learning about cooking. Findings – Three quarters of the sample reported they often or always “cooked from scratch” (CFS). More women than men always CFS; fewer 18-29 year olds did so often or always but more of the over 50s always did so; fewer single people CFS than cohabiting people. No statistically significant ethnic, educational background or household income differences were found. High levels of cooking from scratch were associated with interest in learning more about cooking, greater use of most cooking techniques (except microwaves), meat and legume preparation techniques, and the use of broader ranges of herbs, spice, liquids/ sauces, other ingredients and cooking utensils. Research limitations/implications – In future work a numerical description of the frequency of cooking from scratch should be considered along with a wider range of response options. The data were derived from an online panel from which men were oversampled. Caution is required in comparisons between men and women respondents. The cross-sectional nature of the sample prevents any causal attributions from being drawn from the observed relationships. Further replication of the findings, especially the lack of association with educational background should be conducted. Originality/value – This is the first study to examine the associations of demographic characteristics and cooking practices with cooking from scratch. The findings suggest that cooking from scratch is common among Australian family food providers and signifies interest in learning about cooking and involvement in a wide range of cooking techniques.

Multichannel biomedical time series clustering via hierarchical probabilistic latent semantic analysis

Biomedical time series clustering that automatically groups a collection of time series according to their internal similarity is of importance for medical record management and inspection such as bio-signals archiving and retrieval. In this paper, a novel framework that automatically groups a set of unlabelled multichannel biomedical time series according to their internal structural similarity is proposed. Specifically, we treat a multichannel biomedical time series as a document and extract local segments from the time series as words. We extend a topic model, i.e., the Hierarchical probabilistic Latent Semantic Analysis (H-pLSA), which was originally developed for visual motion analysis to cluster a set of unlabelled multichannel time series. The H-pLSA models each channel of the multichannel time series using a local pLSA in the first layer. The topics learned in the local pLSA are then fed to a global pLSA in the second layer to discover the categories of multichannel time series. Experiments on a dataset extracted from multichannel Electrocardiography (ECG) signals demonstrate that the proposed method performs better than previous state-of-the-art approaches and is relatively robust to the variations of parameters including length of local segments and dictionary size. Although the experimental evaluation used the multichannel ECG signals in a biometric scenario, the proposed algorithm is a universal framework for multichannel biomedical time series clustering according to their structural similarity, which has many applications in biomedical time series management.

Transition from paper to electronic nursing documentation in residential aged care: an actor network theory analysis

Objectives: To examine the role of technology when introduced into the specific setting of residential aged care and then analyse the associated changes to this complex socio-technical network of human and technology actors on the introduction of this technology using the rich lens of Actor Network Theory. Methods: An exploratory qualitative single case study was conducted. The specific focus being the implementation of a nursing information system in an aged care context, i.e. the transition from paper-based nursing documentation to electronic nursing documentation. A series of 19 semi structured interviews with facility managers, nursing coordinators, and the nursing and care staff were conducted. The collected data were analysed using standard qualitative techniques such as thematic analysis and a priori themes were developed from the application of Actor Network Theory. Results: A priori themes coupled with emergent themes served to highlight the impact of a disruptive technology solution into a complex context. Conclusion: An Actor Network Theory analysis enables a rich theoretical lens to be used to examine the introduction of a disruptive technology into a complex context. On such examination critical success factors were identified as well as key barriers. Moreover, people issues were found to be central to the success of such a solution.

Simulation-based baggage handling system merge analysis

This paper details the investigation into the design and control of merging bottlenecks of conveyor-based baggage handling systems, encompassing the merging control algorithm and the impact of the merge's physical layout. A methodology for the analysis of simulation model results is presented. Results show that the layout of the merge influences bag throughput and when the physical configuration is in a preferred position, input variance has no effect on bag throughput performance. These results have potential application to other material handling systems, such as those used in manufacturing and warehousing.
