Business process management in small business : a case study

Small Businesses account for a significant portion of the Australian business sector. With Business Process Management (BPM) gaining prominence in recent decades as a means of improving business performance, it would seem to only be a matter of time before it gains momentum within the Small Business sector. One may even question why it has not already achieved more traction within the sector. This case study involves a BPM initiative to develop process infrastructure in an establishing Small Business. It explores whether mainstream BPM tools, techniques and technologies can be applied in a Small Business setting. The chapter provides a background to the case organisation, outlines the activities undertaken in the BPM initiative and distils key observations drawn from participation in the initiative and consultation with stakeholders. Based on the case study experiences, a number of implications are identified for further consideration by the BPM discipline as it continues to address the question of how it can become more widely adopted amongst Small Businesses.

A hypothesis test using bias-adjusted AR estimators for classifying time series in small samples

A new test of hypothesis for classifying stationary time series based on the bias-adjusted estimators of the fitted autoregressive model is proposed. It is shown theoretically that the proposed test has desirable properties. Simulation results show that when time series are short, the size and power estimates of the proposed test are reasonably good, and thus this test is reliable in discriminating between short-length time series. As the length of the time series increases, the performance of the proposed test improves, but the benefit of bias-adjustment reduces. The proposed hypothesis test is applied to two real data sets: the annual real GDP per capita of six European countries, and quarterly real GDP per capita of five European countries. The application results demonstrate that the proposed test displays reasonably good performance in classifying relatively short time series.

Keyword field-free conjunctive keyword searches on encrypted data and extension for dynamic groups

We consider the following problem: a user stores encrypted documents on an untrusted server, and wishes to retrieve all documents containing some keywords without any loss of data confidentiality. Conjunctive keyword searches on encrypted data have been studied by numerous researchers over the past few years, and all existing schemes use keyword fields as compulsory information. This however is impractical for many applications. In this paper, we propose a scheme of keyword field-free conjunctive keyword searches on encrypted data, which affirmatively answers an open problem asked by Golle et al. at ACNS 2004. Furthermore, the proposed scheme is extended to the dynamic group setting. Security analysis of our constructions is given in the paper.

On secure multi-party computation in black-box groups

We study the natural problem of secure n-party computation (in the passive, computationally unbounded attack model) of the n-product function f G (x 1,...,x n ) = x 1 ·x 2 ⋯ x n in an arbitrary finite group (G,·), where the input of party P i is x i  ∈ G for i = 1,...,n. For flexibility, we are interested in protocols for f G which require only black-box access to the group G (i.e. the only computations performed by players in the protocol are a group operation, a group inverse, or sampling a uniformly random group element). Our results are as follows. First, on the negative side, we show that if (G,·) is non-abelian and n ≥ 4, then no ⌈n/2⌉-private protocol for computing f G exists. Second, on the positive side, we initiate an approach for construction of black-box protocols for f G based on k-of-k threshold secret sharing schemes, which are efficiently implementable over any black-box group G. We reduce the problem of constructing such protocols to a combinatorial colouring problem in planar graphs. We then give two constructions for such graph colourings. Our first colouring construction gives a protocol with optimal collusion resistance t < n/2, but has exponential communication complexity O(n*2t+1^2/t) group elements (this construction easily extends to general adversary structures). Our second probabilistic colouring construction gives a protocol with (close to optimal) collusion resistance t < n/μ for a graph-related constant μ ≤ 2.948, and has efficient communication complexity O(n*t^2) group elements. Furthermore, we believe that our results can be improved by further study of the associated combinatorial problems.

Securing multicast groups in ad hoc networks

We propose a reliable and ubiquitous group key distribution scheme that is suitable for ad hoc networks. The scheme has self-initialisation and self-securing features. The former feature allows a cooperation of an arbitrary number of nodes to initialise the system, and it also allows node admission to be performed in a decentralised fashion. The latter feature allows a group member to determine the group key remotely while maintaining the system security. We also consider a decentralised solution of establishing secure point-to-point communication. The solution allows a new node to establish a secure channel with every existing node if it has pre-existing secure channels with a threshold number of the existing nodes.

Food safety : maximising impact by understanding the food business context

In Australia there are 5.4 million cases of food-borne illness annually which costs the community $1.2 billion per annum (Department of Health and Ageing 2006). As a co-regulator in food safety, local government has a significant interest in ensuring adherence to good food safety practices. This research project involved focus groups or interviews with food business operators and young food handlers to explore their food safety understanding, attitudes, practices and the organisational culture in which they participated. By its nature qualitative research is not intended to provide definitive generalizable findings. Rather the advantage of a small sample size qualitative study is to provide depth rather than breadth. Thus the findings here provide insight into the complexities and nuances of food safety regulation in a manner which a large scale quantitative study could not.

Measurement of small ions near a busy motorway

Combustion sources are well-known sources of electrical ions (Howard, J.B. et al. 1973). Motor vehicles emissions are one of the main sources of ions in urban environments. The presence of charged particles in motor vehicle emissions has been known for many years (Kittelson, 1986; Yu et al, 2004; Jung and Kittelson, 2005). Although these particles are probably charged by the attachment of air ions, there is very little information on the nature, sign and magnitude of the small ions (diameter < 1.6 nm) emitted by motor vehicles and/or present by the sides of roads.

Community arts in early childhood

Community arts can take many forms, including murals, installations, festivals and performances. The work can be produced by artists solely, by artists working with community groups, or by community groups. Community arts can be on a grand-scale covering whole streets, parks or even towns, or small- scale, such as a mosaic in the corner of a play area. It can be extremely impacting and a permanent fixture, or fragile and small and designed to blow away in the wind. But, common to all these different forms of community arts are the criteria that community arts are made in, for and/or by, the local community.

Determining gas sampling timelines for estimating emissions in small chamber incubation experiments

A laboratory experiment was set up in small chambers for monitoring greenhouse gas emissions and determining the most suitable time for sampling. A six-treatment experiment was conducted, including a one week pre-incubation and a week for incubation. Timelines for sampling were 1, 2, 3, 6 and 24 hours after closing the lid of the incubation chambers. Variation in greenhouse gas fluxes was high due to the time of sampling. The rates of gas emissions increased in first three hours and decreased afterward. The rates of greenhouse gas emissions at 3 hours after closing lids was close to the mean for the 24-h period.

A benzothiadiazole end capped donor–acceptor based small molecule for organic electronics

A benzothiadiazole end-capped small molecule 3,6-bis(5-(benzo[c][1,2,5] thiadiazol-4-yl)thiophen-2-yl)-2,5-bis(2-butyloctyl)pyrrolo[3,4-c]pyrrole-1, 4(2H,5H)-dione (BO-DPP-BTZ) using a fused aromatic moiety DPP (at the centre) is designed and synthesized. BO-DPP-BTZ is a donor-acceptor-donor (D-A-D) structure which possesses a band gap of 1.6 eV and exhibits a strong solid state ordering inferred from ∼120 nm red shift of the absorption maxima from solution to thin film. Field-effect transistors utilizing a spin coated thin film of BO-DPP-BTZ as an active layer exhibited a hole mobility of 0.06 cm 2 V-1 s-1. Solution-processed bulk heterojunction organic photovoltaics employing a blend of BO-DPP-BTZ and [70]PCBM demonstrated a power conversion efficiency of 0.9%.

Small firms and health and safety harmonisation : potential regulatory effects of a dominant narrative

Small firms are popularly viewed as resistant to complying with regulation. Harmonisation of Australia’s state-based work health and safety regimes is a significant regulatory change. In this article, we consider the likely responses of small firms to work health and safety harmonisation and argue that a range of choices are open to small firm owner-managers. These choices are shaped by individuals’ world views and are influenced by elements in the firms’ context. A significant element is the public narrative of work health and safety harmonisation, which can be understood by using discourse and sense-making concepts. Our analysis of small firm owner-manager choices takes into account small firms’ embeddedness in their regulatory context and the influence on organisational decision-making of the narrative of work health and safety harmonisation. The dominant narrative is arguably silent on the benefits of the work health and safety regulatory change and therefore the response of small firms is likely to be avoidance or minimalism. Non-compliance could be the result due to poor awareness of opportunities arising from this regulatory change.

Small firms, the paid maternity leave debate in Australia and the business case

Purpose The purpose of this paper is to examine the management of maternity leave in small firms and particularly to explore the perceived costs and benefits of paid maternity leave (PML). PML is a universal right in some countries (i.e. the UK), but not in Australia where most private sector female employees only have access to 12 months unpaid maternity leave. It also aims to explore how the business case for (or against) PML is constructed in small firms. Design/methodology/approach The study was limited to smaller firms operating in the business services sector in the same regional area. Semi‐structured interviews were conducted with eight employers and female employees in six of these firms. Analysis by theme was undertaken within and across interview transcripts. Findings Not one of these small firm employers offered PML and the cost of doing so was not considered to outweigh the benefits already realised through the (legislated) unpaid maternity leave scheme. In these firms maternity leave was managed in an informal way with notions of flexibility – give and take – characterising what happens. Originality/value The paper addresses the lack of research on access to family‐related leave policies in small firms. Employer and employee views of the issue are drawn upon, the latter not often being heard. The paper contributes to understanding the construction of the business case for a specific issue in smaller firms and human resource management from a resource‐based view more generally in smaller firms.

Understanding financial information used to assess small firm performance : an Australian qualitative study

Purpose The purpose of this paper is to investigate the reality of financial and management accounting in a small group of small firms. Specifically, from the owner's perspective, an exploration is undertaken to see what financial information is collected, how it is used (or not) to make business decisions and evaluate the firm's performance, and the role played by the accountant in that process. Design/methodology/approach A phenomenological paradigm underpins this exploratory study. Semi‐structured interviews were undertaken with the owners of ten small firms, where the focus was on understanding what happens in an organisational setting, as opposed to theory and textbook practice. Findings The qualitative data supported prior research in other countries. The in‐depth analysis revealed a very basic understanding of accounting information and problems with the financial literacy amongst these small firm owners. Accounting reports were not widely produced or used, so an informal assessment, such as how much cash was in the bank, was the primary means of assessing business performance. Accountants were used for taxation services, although some owners sought more general business advice. Originality/value An understanding is developed of why there might be a gap between textbook rhetoric and reality of accounting practice in small firms. The conclusion is that accounting textbooks need to include more information about the reality of financial management in small firms.

The effectiveness of workshops as managerial learning opportunities

Purpose The purpose of this paper is to examine the effectiveness of workshops as a learning tool for small business owner‐managers (SBO‐Ms). It aims to concentrate on workshops delivered over 18 months from January 2007 to July 2008 as part of several publicly‐funded small business development programmes in two Australian local government areas (LGAs). Design/methodology/approach Effectiveness is measured in terms of meeting the overarching learning needs and expectations of participants in the context of the programme goals. The paper analyses data gathered from workshop participants either post‐workshop, in later focus groups or through a questionnaire as well as additional feedback from participants and the organisers' reflections. The thematic analysis is organised through an analogy of “going shopping”, where the SBO‐M shopper is buying “learning” when they attend a workshop. Findings Understanding motivation to participate or the “what's in it for me” is important as SBO‐Ms tend to be reluctant, resist or fail to engage with externally sponsored business support initiatives. Workshops were valued for the “space” they create to reflect on practice. For many SBO‐Ms, content “comes alive” with discussion while networking helps reduce the isolation SBO‐Ms can feel. Practical implications The shopping analogy suggests workshops must cater for purposeful shoppers as well as browsers, while interaction with others in the workshop is critical to realising the value of workshops. Originality/value Knowing whether, and how, workshops deliver learning can help to better target and refine these types of support initiatives to ensure they provide positive outcomes for individuals, organisations and economies.
