A touching movement : force control turns machining robots into universal tools

ABB has written a new chapter in the book of robot applications. While in the past it had been a tedious and time-consuming effort to program a robot for delicate fine-tuning operations, robots can now learn how to best manage such tasks themselves. This innovative approach can reduce overall programming times by up to 80 percent for robots used to grind castings, vastly improving productivity levels. With ABB’s new Flex Finishing system featuring RobotWare Machining FC (force control), one of the last real barriers to productivity improvement in this sector has been lifted.

Rapid on-line control to reaching is preserved in children with congenital spastic hemiplegia: evidence from double-step reaching performance

This study aimed to investigate the integrity of on-line control of reaching in congenital spastic hemiplegia in light of disparate evidence. Twelve children with and without spastic hemiplegia (11-17 years old) completed a double-step reaching task requiring them to reach and touch a target that remained stationary for most trials (viz nonjump trial) but unexpectedly displaced laterally at movement onset for a minority of trials (20%: known as jump trials). Although children with spastic hemiplegia were generally slower than age-matched controls, they could account for target perturbation at age-appropriate levels shown by a lack of interaction effect on movement time and nonsignificant group difference for time to reach trajectory correction on jump trials. Our data suggest that at a group level, on-line control of reaching may be age-appropriate in spastic hemiplegia. However, our data also highlight the need to experimentally acknowledge the considerable heterogeneity of the spastic hemiplegia population when investigating motor cognition.

Dannevirke’s fashion capital: The fashion and Silvalyne Gowns

Although not known as a ‘fashion capital’, for young emigrant Norman Alexander, Dannevirke in 1927 was a style opportunity waiting to be served. This paper takes as its case study, the work of Alexander through his Dannevirke-based fashion company ‘Silvalyne Gowns’ and his High Street retail outlet ‘The Fashion’. New Zealand’s fashion design history has been increasingly interrogated over the past decade, and often gives privilege to those who have found success overseas, or who were primarily located in New Zealand’s main centers. Only occasionally does research touch on smaller towns and the role they too played in New Zealand’s fashion history. By placing emphasis on a smaller, less well-known town this paper seeks to redress this balance and open up enquiry about how the town and the country may also be positioned alongside the better-known fashion centers.

Collapse: Clouds of affective dust

All objects emerge from a cloud of activities, virtual pressures and situated encumbrances that precede their status as finished things. Once emerged, traces of their history linger in the object, signposting a range of past and future potentials that are largely inaccessible – or just unnoticed. Objects, in short, always shimmer with connections beyond themselves, through which they are part of ecologies that render them both meaningful and active. We would call this shimmering their ‘abstract life’. However, this life is rarely identified overtly, and tends to linger in the background, rendering their shimmering vitality more mute than manifest. This paper is interested in how that abstract life can become palpably evident though various forms of collapse, where a fallout throws a kind of dust into the lingering cloud – offering visibility, or material presence, to the otherwise largely invisible, abstract life of things. We will touch upon a series of examples, from the World Trade Centre collapse in the attacks of 2001, to the collapse of computational operations and perceptual models. These examples will lead toward experiments in image making – specifically through using panorama software applications on the iPhone – in which a collapse of the programmed panoramic logic creates ‘glitches’, throwing into question the status of the image and their relationship to perception, amongst other things. These experiments will be discussed in order to demonstrate how collapse might operate as a specific technique inside diverse creative practices (from image making to making architecture). By generating clouds of affective dust, related techniques can bring the abstract ‘life’ of objects flickering into the foreground, allowing the agency of the inanimate to shine.

Singaporean Parents’ Views of Their Young Children’s Access and Use of Technological Devices

Debates continue about the access young children have to technological devices, given the increasingly accessible and available technology in most developed countries. Concerns have been expressed by parents/caregivers and researchers, and questions have been raised about possible risks and benefits of these devices on young children who, in some instances, may be accessing these devices daily. Levin (2013) states that it is as if children are being remote controlled by the scripts of others (television, videos, electronic toys) which undermine children’s abilities to create their own learning scripts. This study investigated 1,058 parents’/caregivers’ views of their children’s (aged below 7 years) access and time spent on technology devices. Parents’/caregivers’ views on risks and benefits associated with the use of the emerging touch screen devices were also sought. The context for this research was Singapore which, according to a survey in 2012 by Ericsson, has one of the highest usage rates of smartphones and touchscreen devices in the world. The findings may help researchers, parents/caregivers and teachers to further their understanding of young children’s development in the twenty-first century.

The Tablet PC: A Complete Teaching Studio

The Tablet PC is a flexible teaching tool. It can be used to increase the lecturer’s productivity in note taking and in assignment marking. It can be used in the lecture room with increased interaction. With a few minor accessories it can be used to record all aspects of a lecture or presentation. It can also be used to record short topic segments that can be used as references or summaries by students. Containing the abilities of both a tablet device with multi touch, a pen interface for accurate drawing and handwriting and with the power of a full PC, it is a complete teaching studio.

Deficient cognitive control fuels children's exuberant false allegations.

In eyewitness studies as in actual investigations, a minority of children generate numerous false (and sometimes incredulous) allegations. To explore the characteristics of these children, we reinterviewed and administered a battery of tasks to 61 children (ages 4-9 years) who had previously participated in an eyewitness study where a man broke a "germ rule" twice when he tried to touch them. Performance on utilization, response conflict (Luria tapping), and theory of mind tasks predicted the number of false reports of touching (with age and time since the event controlled) and correctly classified 90.16% of the children as typical witnesses or exuberant (more than 3) false reporters. Results of a factor analysis pointed to a common process underlying performance on these tasks that accounted for 49% of the variability in false reports. Relations between task performance and testimony confirmed that the mechanisms underlying occasional intrusions are different from those that drive persistent confabulation and that deficient cognitive control fuels young children's exuberant false reports.

Exploring the later life relationship between adults with cerebral palsy and their non-disabled siblings

 Purpose: Adults with moderate or severe cerebral palsy often require significant lifetime support from family and formal services. The aim of this study was to use a life course approach to explore how previous life experiences impact on the later life relationships of people with moderate to severe cerebral palsy aged 40 years and over and their non-disabled siblings. Method: Twelve adults with moderate to severe cerebral palsy and 16 of their non-disabled siblings were interviewed twice to explore their relationships. Constructivist grounded theory method was used to analyse the data. Results: Four themes were identified as important in understanding these later life sibling relationships: sharing childhood experiences, contact in adulthood, diminishing parental role and increasing support needs. Conclusions: The life course approach indicated that siblings' growing up together was important for the development and maintenance of emotional closeness later in life. Emotional closeness and familial obligation were important factors in motivating siblings with and without cerebral palsy to maintain or re-establish contact with each other in adulthood. Maintenance of sibling relationships in later life is dependent on health, proximity and the ability to keep in contact with each other.Implications for RehabilitationAs adults with severe cerebral palsy live longer, their relationships with non-disabled siblings often take on increased importance and particularly as their parents may be no longer able to provide support.Service providers have a role in helping ageing siblings with and without disability to maintain and build their relationships, for example, by supporting geographically distant siblings to keep in touch.Service providers have a role in supporting the person with a disability and their siblings to make plans for the future. © 2014 Informa UK Ltd.

Disenchantments of secularism: the West and India

This Chapter is an exercise in comparative secularism. In this chapter I will be concerned basically with a critique of Western conceptions of secularism, beginning with Hegel’s invention of a particular reading of secularism that, through imperialist literature, gave a preeminent direction to the ideology of the less-religiously orientated Indian nationalists during their drawn-out independence struggle. My main concern will be to contrast the Western debates on ‘the secular’, particularly in its recent permutations or attempted revisions as a response to the crisis of modernity, with the current Indian debates—where ‘ the secular; has all but been hijacked by the Hindu Right—and to show—reversing Hegel’s trajectory—what impact the latter could have on the former. There is some evidence of this already occurring, particularly in Charles Taylor’s work and travels wherein he does make some gestures towards looking at non-Western experiences of secularism (which is taken more or less to be synonymous with secularization). There are severe limitations to this overture however, and the chapter hopes to sound a word of caution on the kind of excitement over which Taylor seems to have become something of a celebrity in the academe. Even more disappointingly, one does not find a similar emphatic approach or opening to non-Western experiences and rethinking of the secular in the works of other modernists; and I point to Habermas and Žižek as my examples, who I touch on, albeit very briefly. This lack or lacuna makes both the discourse of modernity and the supplementary critique of secularism much the poorer for it.

Touching space: Using motion capture and stereo projection to create a "virtual haptics" of dance

This paper describes the work of a group of artists in Australia who used real-time motion capture and 3D stereo projection to create a large-scale performance environment in which dancers seemed to "touch" the volume. This project re-versions Suzanne Langer's 1950s philosophy of dance as "virtual force" to realize the idea of a "virtual haptics" of dance that extends the dancer's physical agency literally across and through the surrounding spatial volume. The project presents a vision of interactive dance performance that "touches" space by visualizing kinematics as intentionality and agency. In doing so, we suggest the possibility of new kinds of human-computer interfaces that emphasize touch as embodied, nuanced agency that is mediated by the subtle qualities of whole-body movement, in addition to more goal-oriented, task-based gestures such as pointing or clicking. © 2010.

DNA transfer by examination tools--a risk for forensic casework?

The introduction of profiling systems with increased sensitivity has led to a concurrent increase in the risk of detecting contaminating DNA in forensic casework. To evaluate the contamination risk of tools used during exhibit examination we have assessed the occurrence and level of DNA transferred between mock casework exhibits, comprised of cotton or glass substrates, and high-risk vectors (scissors, forceps, and gloves). The subsequent impact of such transfer in the profiling of a target sample was also investigated. Dried blood or touch DNA, deposited on the primary substrate, was transferred via the vector to the secondary substrate, which was either DNA-free or contained a target sample (dried blood or touch DNA). Pairwise combinations of both heavy and light contact were applied by each vector in order to simulate various levels of contamination. The transfer of dried blood to DNA-free cotton was observed for all vectors and transfer scenarios, with transfer substantially lower when glass was the substrate. Overall touch DNA transferred less efficiently, with significantly lower transfer rates than blood when transferred to DNA-free cotton; the greatest transfer of touch DNA occurred between cotton and glass substrates. In the presence of a target sample, the detectability of transferred DNA decreased due to the presence of background DNA. Transfer had no impact on the detectability of the target profile, however, in casework scenarios where the suspect profiles are not known, profile interpretation becomes complicated by the addition of contaminating alleles and the probative value of the evidence may be affected. The results of this study reiterate the need for examiners to adhere to stringent laboratory cleaning protocols, particularly in the interest of contamination minimisation, and to reduce the handling of items to prevent intra-item transfer.

Residual DNA on examination tools following use

Recent studies observing the transfer of DNA via examination tools used within forensic laboratories (scissors, forceps and gloves) have highlighted the contamination risk of such implements if protocols following their use and replacement are not adhered to. Whilst these previous studies focus primarily on the transfer of biological substances to a substrate via high-risk vectors, this investigation considers the proportion of DNA that remains on the high-risk vectors following contact with the substrate. Dried blood or touch DNA was deposited on cotton or glass substrates to create mock exhibits. Following primary contact with the deposit, the vector similarly contacted a secondary DNA-free substrate. Combinations of singular and multiple contacts were applied. Immediately following contact with the secondary substrate, the vector was sampled in order to determine the proportion of DNA-containing material remaining on the vectors following contacts. Residual DNA was detected on the vectors in most instances, with the amount retained influenced by the vector, substrates and biological substance applied. The results demonstrate the potential for inter- and intra-exhibit contamination through further contacts.

Activities between activities of focus-Relevant when assessing DNA transfer probabilities

Consideration of the indirect transfer of 'touch DNA' is increasingly becoming part of criminal investigations. Focus is often concentrated on the actions relating to the pick-up of the relevant DNA and key actions associated with transfer to the exhibit from which the sample in question was collected. There is often a time lapse between such actions. As any contact can influence the gain and/or loss of DNA, it is relevant to have an awareness of what hands touch during everyday activities in order to assist consideration of what may be occurring during potential time lapses within contemplated scenarios. To gain an appreciation of the manner and frequency of hands contacting various surfaces during everyday activities, we analysed several videos of individuals performing a variety of general activities. The findings indicate that several items are touched over a relatively short period of time. Appreciation and consideration of general activities that may have occurred between key focus activities are necessary to assess any impact these may have on what is deposited at the final collection site. The information this provides is imperative when weighting alternative transfer scenario propositions.

Digital marketing of unhealthy foods to Australian children and adolescents

The emergence of new media—including branded websites, social media and mobile applications—has created additional touch points for unhealthy food and beverage companies to target children and adolescents. The aim of this study was to perform an audit of new media for three top selling food and beverage brands in Australia. The top selling brand in three of the most advertised food and beverage categories was identified. Facebook, websites and mobile phone applications from these three brands were assessed using a combination of descriptive analyses and structured data collection during June and July 2013. Information on target audience, main focus of the activity, marketing strategies employed and connectivity were collected. Promotional activities were assessed against industry self-regulatory codes. McDonald's, Coca-Cola and Cadbury Dairy Milk were audited, with 21 promotional activities identified. These promotional activities appeared to use a number of marketing strategies, with frequent use of indirect product association, engagement techniques and branding. We identified strategic targeting of both children and adolescents. We found that while all promotional activities technically met self-regulatory codes (usually due to media-specific age restrictions) a number appeared to employ unhealthy food or beverage marketing directed to children. Brands are using engaging content via new media aimed at children and adolescents to promote unhealthy food and beverages. Given the limitations of self-regulatory codes in the context of new media, strategies need to be developed to reduce exposure of children and adolescents to marketing of unhealthy food and beverage products via these avenues.
