User Review-Based Change File Localization for Mobile Applications

In the current mobile app development, novel and emerging DevOps practices (e.g., Continuous Delivery, Integration, and user feedback analysis) and tools are becoming more widespread. For instance, the integration of user feedback (provided in the form of user reviews) in the software release cycle represents a valuable asset for the maintenance and evolution of mobile apps. To fully make use of these assets, it is highly desirable for developers to establish semantic links between the user reviews and the software artefacts to be changed (e.g., source code and documentation), and thus to localize the potential files to change for addressing the user feedback. In this paper, we propose RISING (Review Integration via claSsification, clusterIng, and linkiNG), an automated approach to support the continuous integration of user feedback via classification, clustering, and linking of user reviews. RISING leverages domain-specific constraint information and semi-supervised learning to group user reviews into multiple fine-grained clusters concerning similar users' requests. Then, by combining the textual information from both commit messages and source code, it automatically localizes potential change files to accommodate the users' requests. Our empirical studies demonstrate that the proposed approach outperforms the state-of-the-art baseline work in terms of clustering and localization accuracy, and thus produces more reliable results.Comment: 15 pages, 3 figures, 8 table

mFish Alpha Pilot: Building a Roadmap for Effective Mobile Technology to Sustain Fisheries and Improve Fisher Livelihoods.

In June 2014 at the Our Ocean Conference in Washington, DC, United States Secretary of State John Kerry announced the ambitious goal of ending overfishing by 2020. To support that goal, the Secretary's Office of Global Partnerships launched mFish, a public-private partnership to harness the power of mobile technology to improve fisher livelihoods and increase the sustainability of fisheries around the world. The US Department of State provided a grant to 50in10 to create a pilot of mFish that would allow for the identification of behaviors and incentives that might drive more fishers to adopt novel technology. In May 2015 50in10 and Future of Fish designed a pilot to evaluate how to improve adoption of a new mobile technology platform aimed at improving fisheries data capture and fisher livelihoods.

The Digitalisation of African Agriculture Report 2018-2019

An inclusive, digitally-enabled agricultural transformation could help achieve meaningful livelihood improvements for Africa’s smallholder farmers and pastoralists. It could drive greater engagement in agriculture from women and youth and create employment opportunities along the value chain. At CTA we staked a claim on this power of digitalisation to more systematically transform agriculture early on. Digitalisation, focusing on not individual ICTs but the application of these technologies to entire value chains, is a theme that cuts across all of our work. In youth entrepreneurship, we are fostering a new breed of young ICT ‘agripreneurs’. In climate-smart agriculture multiple projects provide information that can help towards building resilience for smallholder farmers. And in women empowerment we are supporting digital platforms to drive greater inclusion for women entrepreneurs in agricultural value chains

The Impact of Regulatory Changes on the Development of Mobile Medical Apps

Mobile applications are being used to perform a wide variety of tasks in day-to-day life ranging from checking email, to controlling your home heating. Application developers have recognized the potential to transform a smart device into a medical device, by using a mobile medical application i.e. a mobile phone or a tablet. When initially conceived these mobile medical applications performed basic functions e.g. BMI calculator, accessing reference material etc.; however, increasing complexity offers clinicians and patients a range of functionality. As this complexity and functionality increases, so too does the potential risk associated with using such an application. Examples include any applications that provide the ability to inflate and deflate blood pressure cuffs, as well as applications that use patient-specific parameters and calculate dosage or create a dosage, plan for radiation therapy. If an unapproved mobile medical application is marketed by a medical device organization, then they face significant penalties such as receiving an FDA warning letter to cease the prohibited activity, fines and possibly face criminal conviction. Regulatory bodies have finalized guidance intended for mobile application developers to establish if their applications are subject to regulatory scrutiny. However, regulatory controls appear contradictory with the approaches taken by mobile application developers who generally work with short development cycles and very little documentation and as such, there is the potential to stifle further improvements due to these regulations. The research presented as part of this paper details how by adopting development techniques such as agile software development, mobile medical application developers can meet regulatory requirements whilst still fostering innovation

Supporting ‘Good Habits’ through User-Led Design of Food Safety Applications – Findings from a Survey of Red Meat Consumers

Mitigating consumer health risks and reducing food wastage has stimulated research into mechanisms for improving consumers’ food safety knowledge and food management practice. Many studies report success, but differences in methodology and in the type and range of foods and consumers involved has made comparison and transferability of results challenging. While most studies advocate for the importance of information in consumer education, few provide detailed insight into what ‘good’ information means. Determining appropriate content, formats, and methods of delivery for different types of consumers as well as evaluating how different choices impact on consumers’ food safety knowledge and behaviour remains unclear. Within a larger research project on enhancing provenance, stability and traceability of red meat value chains, this paper presents findings from a survey of Australian red meat consumers (n=217). It identifies consumers’ food safety issues and reveals information and communication preferences that may support good safety habits with food

A STRATEGIC VIEW ON INTERTWINING DIGITAL AND PHYSICAL MATERIALITIES ACROSS LIFECYCLES OF PRODUCTS AND SERVICES

Opportunities to use virtual, augmented, and mixed reality (VAM-R) are emerging in various sectors of the economy. To seize them, managers need to develop comprehensive strategies that intertwine digital and physical forms of materiality. This paper proposes a way to assess and steer the transformations of the reality-virtuality continuum across lifecycles of products and services. Our approach identifies use cases for VAM-R according to the (1) strategic imperative, (2) physical materiality, (3) reality-virtuality assessment, (4) digital materiality, (5) information value, and (6) project portfolio. The findings result from three action research cycles in manufacturing and healthcare. For theory, we propose a framework to evaluate the reality-virtuality continuum and guide VAM-R transformations. For practice, we propose and test an artefact accessible to domain experts with different backgrounds, and a sequence of steps to assist managers in their digitalization strategies with VAM-R. Lifecycle approaches offer an alternative perspective to situational transformation, potentially improving the pervasiveness of organizational changes using information technologies

Blockchain-based Provenance Solution for Handcrafted Jewellery

Käsitsi tehtud ehete valmistamiseks kasutatakse tootmismasinate asemel inimeste kätetööd. Kui masinate poolt tehtud ehted on samasugused, odavad ja kergesti kättesaadavad, siis käsitsi valmistatud ehted on ainulaadsed ja küllaltki kallid. Seda eriti siis, kui tegemist on tuntud käsitöölise või disaineriga. Käesolev tehnoloogiaajastu on tõstnud tarbijate teadlikkust ning inimesed on valmis rohkem maksma tõestatud päritoluga toodete eest. Samuti soovivad tootjad oma töö eest saada tunnustatud ja omada selle õigusi. Praegused lahendused on pärituolu osas poolikud ning see võimaldab tarneahelal olla läbipaistmatu ning seetõttu kõrvale hiilida läbipaistvusest ning jälgitavusest. Seetõttu on hüppeliselt kasvanud võltstoodangu arv, mis toob kaasa majandusliku ja keskkondliku kahju, terviseriskid, valdkonna halva maine ning rikutud usalduse. Käesolev dissertatsioon vaatleb ja selgitab plokiahela tehnoloogial põhinevaid lahendusi ja võimalusi taustakontrolli tegemiseks ning teostab Ethereumi plokiahelal põhineva lahenduse käsitööehete päritolu kontrolliks. Uurimuse tulemus aitab kaasa taustakontrollimehhanismide arengule ning aitab seda rakendada ülemaailmse tarneahela läbispaistvamaks muutmisel.Handcrafted jewellery involves use of hand labour rather than manufacturing machinery. Unlike manufactured jewellery which is similarly crafted, cheap and easy to find, handcrafted jewellery tend to be uniquely crafted and fairly expensive, especially when it is attributed to a well known artisan or designer. The current information age has birthed a new era of conscious consumers who are willing to pay more for products with proven origins. Likewise, creators desire to be rightfully attributed and acknowledged for their work. However, the partial implementation of provenance by current solutions has encouraged opaque supply chains that hinder transparency and traceability. For this reason, there has been a rapid increase in counterfeit products, unprecedented economic loss, environmental degradation, health risks, increase in defamation cases, and broken trust. In this thesis, we review related provenance solutions using blockchain technology, identify key provenance features and implement a provenance solution for handcrafted jewellery on Ethereum blockchain. The output of this research can be used towards the development of provenance as a subject and its implementation in global supply chains
