The purpose of this paper is to explore how people differently create meaning from photos taken by either a lifelogging camera (LC) (i.e. automatic capture) or a mobile phone camera (MC) (i.e. manual capture). Moreover, the paper investigates the different changes in the interpretative stance of lifelog photos and manually captured photos over time to figure out how the LC application could support the users’ iconological interpretation of their past.

A 200-day longitudinal study was conducted with two different user groups that took and reviewed photos taken by either a LC or a MC. The study was structured in two phases: a photo collection phase, which lasted for five days (Day 1‒Day 5), and a three-part semi-structured interview phase, which was conducted on Days 8, 50 and 200.

Results revealed that the interpretative stance of the LC group changed greatly compared to the MC group that kept a relatively consistent interpretative stance over time. A significant difference between the two groups was revealed on Day 200 when the lifelog photos provoked a more iconological and less pre-iconographical interpretative stance. This stance allowed the viewers of lifelog photos to systemically interpret the photos and look back upon their past with different viewpoints that were not recognized before.

This paper contributes to further understand the dynamic change in interpretative stance of lifelog photos compared to manually captured photos through a longitudinal study. The results of this study can support the design guidelines for a LC application that could give opportunities for users to create rich interpretations from lifelog photos.

The aim of the study is to conduct a thematic review of assessment tools and types of activities in the application of robotics to autistic students during the period 1996–2021 using Web of Science and Scopus. The sample consisted of 119 documents.

Nowadays, emerging technologies have become increasingly prevalent across various fields of knowledge. In this regard, robotics is being increasingly applied in the educational environment. The characteristics of this tool are the ones that best suit the needs of autistic students.

Results reveal that 16.80% of the studies used automatic measurement systems, whilst 15.96% of the studies used user observation and recording techniques. As for the tasks, 37.80% were focussed on imitation tasks. Amongst the practical implications is the need to include tasks that could be developed collaboratively in the regular classroom.

With this research, it is intended to disseminate in the scientific community what are the characteristics that should have the interaction activities between a robot and autistic students. In addition, the type of tool needed to evaluate the improvements in the interaction is proposed.

A shock capturing scheme is presented for the equations of isentropic flow based on upwind differencing applied to a locally linearized set of Riemann problems. This includes the two‐dimensional shallow water equations using the familiar gas dynamics analogy. An average of the flow variables across the interface between cells is required, and this average is chosen to be the arithmetic mean for computational efficiency, leading to arithmetic averaging. This is in contrast to usual ‘square root’ averages found in this type of Riemann solver where the computational expense can be prohibitive. The scheme is applied to a two‐dimensional dam‐break problem and the approximate solution compares well with those given by other authors.

The purpose of this paper is to describe miscommunication about the ubiquitous term “supply chain visibility” (SCV), to propose a precise definition for it and identify its salient characteristics.

A literature search was conducted to describe the widespread use of the term SCV and the miscommunication that occurs surrounding its use. The proposed definition and the salient characteristics of SCV are original conceptual contributions.

The study finds that the term SCV is widely used in the supply chain management and logistics communities Many vendors, third party logistics providers, transportation and other companies profess to have or provide it, yet SCV remains one of the top issues consistently mentioned in surveys of supply chain management professionals. This occurs in part because of the confusion surrounding its meaning.

Usage of the term SCV is ubiquitous and a complete review of all sources is not possible, revealing over 348,000 sources from internet and academic database searches. Only selected, key results are from these sources are reported. The proposed definition for and characterization of SCV are the author's conceptual contributions, open to discussion and debate.

A precise definition of SCV along with its important attributes helps to promote consistent understanding, interpretation and to clarify communications, especially between vendors and logistics service providers.

The proposed definition is new, as well as the discussion of its important attributes and implications.

The purpose of this paper is to assess examples of digital recordkeeping practice in the Australian state of New South Wales (NSW) and determine whether the discipline is tipping into a period where digital recordkeeping will change for the better, or whether it is tipping into digital oblivion. After assessing numerous case studies and examples, the paper also seeks to recommend some small but significant steps that can be taken to stem the tide and improve digital recordkeeping practices.

The approach is based on the authors' experiences and observations of recordkeeping practice in NSW.

Digital records and recordkeeping are at a critical juncture across all business environments. The tremendous benefits that digital records and recordkeeping can realise are in danger of being offset by significant threats, complexities and costs. All individuals, organisations and business environments need to take small steps now to start to make digital recordkeeping achievable and to make long‐term digital record sustainability possible.

The case studies presented in this paper provide both positive and negative digital recordkeeping scenarios for practitioners to consider. The paper also makes a number of practical suggestions that all recordkeeping environments can reflect on to tip the balance in favour of achievable and sustainable digital recordkeeping.

The paper is of value to all practitioners seeking to implement and sustain effective digital records management.

We describe an automatic classroom capture system that detects and records significant (stable) points in lectures by sampling and analyzing a sequence of screen capture frames from a PC used for presentations, application demonstrations, etc. The system uses visual inspection techniques to scan the screen capture stream to identify points to store. Unlike systems that only detect and store slide presentation transitions, this system detects and stores significant frames in any style of computer‐based lecture using any program. The system is transparent to the lecturer and requires no software or training. It has been tested extensively on lectures with multiple applications and pen‐based annotations and has successfully identified “significant” frames (frames that represent stable events such as a new slide, bullet, figure, inked comment, drawing, code entry, application entry etc.). The system can analyze over 20000 frames and typically identifies and stores about 100 significant frames within minutes of the end of a lecture. A time stamp for each saved frame is recorded and will in the future be used to compile these frames into a jMANIC multimedia record of the class.

This paper aims to examine the effectiveness of organizational information technology (IT)-based and non-IT-based knowledge transfer mechanisms (KTMs) for the retention of different types of knowledge from mobile experts. It differentiates among four types of knowledge loss (KL), namely, conscious knowledge (i.e. individual explicit knowledge that can be codified); codified knowledge (i.e. explicit knowledge captured at the social level); automatic knowledge (i.e. implicit individual knowledge); and collective knowledge (i.e. implicit knowledge embedded in the organization).

A research framework connecting the organizational knowledge retention (KR) cycle to KL is developed and an exploratory analysis is conducted using data from two case studies in the Canadian federal public service. Findings are confirmed using a third government agency.

Without the right processes in place for organizational knowledge retrieval and reuse, the KR cycle is not complete, leading to KL. The lack of available social KTMs for the conversion of individual to social objectified knowledge leads to KL. KTMs shortcomings increase the risk of automatic and objectified KL.

Exploratory results demonstrate that KL does not always equate to lack of KR. Implementing knowledge-specific organizational KTMs is important to encourage the retention of individual knowledge at the social level. Propositions and a framework are developed for future research.

Mobile experts hold valuable knowledge at high risk of being lost by organizations. This paper provides managers with a set of guidelines to develop a knowledge-specific strategy focused on KTMs that increase KR and mitigate KL.

This paper challenges the assumption that KL only results from poor retention and studies both retention and loss to identify additional types of unintentional loss that occur when individual knowledge is not converted to social knowledge.

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

THE automatic flight control system (AFCS) for the Concorde has been jointly developed by Elliott‐Automation Ltd. and SFENA (Société Francaise pour la Navigation Aérienne) for the production aircraft. Elliott carry the overall design responsibility and the equipment will be supported in the field by both Elliott and SFENA. The pitch axis of the autopilot and flight director, the autothrottle, all aspects of the control of speed, all pilot/ AFCS interfaces and the landing display are Elliott responsibilities for the pre‐production and production aircraft, while SFENA are responsible for the three‐axis autostabiliser, azimuth axes of the autopilot and flight director, electric trim system and the flight test instrumentation for the AFCS. The Bendix Corporation participated in the programme for the prototype aircraft with the design and manufacture of the azimuth axes of the autopilot and flight director, and the electric trim system.
