Understanding the key drivers of and technology related issues associated with going multi-channel

A multi-channel retail strategy is viewed by many academics and practitioners to be the success model for most retailers. Yet, while there are many drivers of, and advantages related to, using multiple channels to sell products and services to customers likewise there are numerous technology-related issues. Despite this, the multi-channel retailing literature provides little empirical insight into these technology-related constraints. Moreover, there is a lack of multi-channel retailing research which explores the impetuses behind retailers adding new channels to go multi-channel, especially in the context of the UK retail sector. To contribute to gaps in the literature this study utilises a case study research strategy to examine the key motivations behind, and technology-related issues associated with, multi-channel retail strategic implementation, in the setting of the UK retail sector. Three UK based retailers (Boots, Screwfix and Bettys) are used which have different approaches to, and are at different stages of, adopting a multi-channel retail strategy. In addition, they have different backgrounds such as size, product range, sector and type. Consequently, the use of these three different retailers enables exploration of the drivers behind, and technological problems associated with, implementing a multi-channel retail strategy in the context of store and Internet/catalogue retailers. Case analysis reveals novel themes which are not identified, or not clearly recognised, in the literature. These include that key drivers behind retailers going multi-channel are to increase sales, and, meet the needs of the multi-channel shopper. Indeed, customers want to shop via multiple channels and therefore, these retailers have no choice but to go multi-channel if they are to meet customer needs. However, while at a strategic level these motivations were similar across the case study retailers, they also differed. For example, Screwfix added a store channel to enable customers to purchase products and receive them instantly. In contrast, Boots added an Internet channel to drive footfall in-store and increase store sales. Boots were also adding an Internet channel since it provided them with a marketing channel, which, going forward, was likely to replace other communications channels. The findings from this study also reveal that retailers encounter major technology-related issues when adding new, and using multiple, channels. These problems stem from the need to re-design existing logistics and IT infrastructure to offer a seamless, integrated offer to the customer. For instance, to leverage the brand and marketing mix consistently across all channels, and, to implement ‘click and collect’ (i.e. where customers purchase a product in one channel and collect it in another). Also, due to the need to use innovative marketing techniques, in particular, social media. Importantly, this study highlights that these technology-related multi-channel retailing constraints often have a ‘softer’ side. Technology-related problems are frequently intertwined with cultural, engagement and financial/staff resource related issues. This suggests a need for retailers to find entwined solutions to both technology and non- technology related issues to effectively implement a multi-channel retail strategy

The influence of ship motion of manual control skills

The effects of ship motion on a range of typical manual control skills were examined on the Warren Spring ship motion simulator driven in heave, pitch, and roll by signals taken from the frigate HMS Avenger at 13 m/s (25 knots) into a force 4 wind. The motion produced a vertical r.m.s. acceleration of 0.024g, mostly between 0.1 and 0.3 Hz, with comparatively little pitch or roll. A task involving unsupported arm movements was seriously affected by the motion; a pursuit tracking task showed a reliable decrement although it was still performed reasonably well (pressure and free moving tracking controls were affected equally by the motion); a digit keying task requiring ballistic hand movements was unaffected. There was no evidence that these effects were caused by sea sickness. The differing response to motion of the different tasks, from virtual destruction to no effect, suggests that a major benefit could come from an attempt to design the man/control interface onboard ship around motion resistant tasks

Computational analysis of the LRRK2 interactome.

LRRK2 was identified in 2004 as the causative protein product of the Parkinson's disease locus designated PARK8. In the decade since then, genetic studies have revealed at least 6 dominant mutations in LRRK2 linked to Parkinson's disease, alongside one associated with cancer. It is now well established that coding changes in LRRK2 are one of the most common causes of Parkinson's. Genome-wide association studies (GWAs) have, more recently, reported single nucleotide polymorphisms (SNPs) around the LRRK2 locus to be associated with risk of developing sporadic Parkinson's disease and inflammatory bowel disorder. The functional research that has followed these genetic breakthroughs has generated an extensive literature regarding LRRK2 pathophysiology; however, there is still no consensus as to the biological function of LRRK2. To provide insight into the aspects of cell biology that are consistently related to LRRK2 activity, we analysed the plethora of candidate LRRK2 interactors available through the BioGRID and IntAct data repositories. We then performed GO terms enrichment for the LRRK2 interactome. We found that, in two different enrichment portals, the LRRK2 interactome was associated with terms referring to transport, cellular organization, vesicles and the cytoskeleton. We also verified that 21 of the LRRK2 interactors are genetically linked to risk for Parkinson's disease or inflammatory bowel disorder. The implications of these findings are discussed, with particular regard to potential novel areas of investigation

Development and test of video systems for airborne surveillance of oil spills

Five video systems - potentially useful for airborne surveillance of oil spills - were developed, flight tested, and evaluated. The systems are: (1) conventional black and white TV, (2) conventional TV with false color, (3) differential TV, (4) prototype Lunar Surface TV, and (5) field sequential TV. Wavelength and polarization filtering were utilized in all systems. Greatly enhanced detection of oil spills, relative to that possible with the unaided eye, was achieved. The most practical video system is a conventional TV camera with silicon-diode-array image tube, filtered with a Corning 7-54 filter and a polarizer oriented with its principal axis in the horizontal direction. Best contrast between oil and water was achieved when winds and sea states were low. The minimum detectable oil film thickness was about 0.1 micrometer

Icing and De-Icing of a Propeller with Internal Electric Blade Heaters

An investigation has been made in the NACA Cleveland icing research tunnel to determine the de-icing effectiveness of an experimental configuration of an Internal electric propeller-blade heater. Two atmospheric Icing conditions and two propeller operating conditions were Investigated, In experiments with unheated blades and with heat applied to the blades both continuously and cyclically. Data are presented to show the effect of propeller speed., ambient air temperature and liquid-water concentration, and the duration of the heat-on and cycle times on the power requirements and de-Icing performance of the blade heaters. The extent of ice-covered area on the blades for various icing ax4 operating conditions has been determined. The largest iced area was obtained at the higher ambient-air temperatures and at low propeller speed. The ohord.wise extent of Icing In practically every case was greater than that covered by blade heaters. Adequate de-icing in the heated area with continuous application of heat was obtained with the power available but a maximum power, input of 1250 watts per blade was insufficient for cyclic de-Icing for the range of conditions investigated. Blade-surface temperature rates of rise of 0.2 to 0.7 F per second were obtained and the minimum cooling period for cyclic de-icing was found to be approximately 2-1/2 times the heating period

Using an ontology for interoperability and browsing of museum, library and archive information

Ontologies play an important part in the development of the future ‘semantic web’; the CIDOC conceptual reference model (CRM) is an ontology aimed at the cultural heritage domain. This paper describes a Concept Browser, developed for the EU/IST-funded SCULPTEUR project (semantic and content-based multimedia exploitation for European benefit environment (programme IST-2001-no. 35372); May 2002 to May 2005), which is able to access different museum information systems through a common ontology, the CRM. The development of this Concept Browser has required mappings from the legacy museum database systems to the CRM. The crucial process of creating the mappings is described, using the C2RMF catalogue (EROS) and library databases as a case study
