Kiosks in retailing: the quiet revolution

Kiosks have the potential to be a significant application of IT in retailing, information provision and service delivery. This article discusses and analyses the application of kiosks as a channel for in-store service delivery. For these kiosks a taxonomy that characterises kiosks by their function: inform, interact, transact and relate is proposed. Eight case study examples of in store kiosks are analysed in using a framework that includes environment, task, audience, and technology. Included are: kiosks used by Halifax, Daewoo, Argos, Ikea, Debenhams, GNER, Sainsbury’s. and Boots. Both the taxonomy and the framework provide a basis for further analysis of the role of kiosks in service delivery, by allowing analysis and discussion of individual kiosks to be contextualised within a wider framework. </p

Online kiosks: the alternative to mobile technologies for mobile users

Online kiosks have the potential to be a significant alternative to mobile technologies in retailing, information provision and service delivery. This article describes the development and use of different types of online kiosk in contexts where users are on the move and away from fixed technologies. A case study of a major UK airport terminal is used to illustrate different types of kiosk applications. Comparisons are made with mobile phone technologies. Online kiosks have a niche in allowing access to information, services and e-commerce technologies for all potential consumers. However, they also have a much wider role in self-managed, self-service delivery of information, services, goods and relationships to consumers on the move.</p

What is the future for undergraduate dissertations?

This article argues that the changing nature of the dissertation experience, and its associated supervision calls for more detailed attention to the development of dissertation supervisors. Dissertations have always played a major role in student learning. The following themes constitute the kernel of the article: the role of the dissertation in the student’s learning experience, managing the link between theory and practice, digitization of information resources, research methodologies and design, and finally, the implications for the role of the supervisor. It is suggested that without an awareness of the changing nature of the dissertation experience, and a more proactive approach to supervisor development, there may be serious degradation of the dissertation experience and outcomes.</p

The Nefarious Nexus of Noncoding RNAs in Cancer

The past decade has witnessed enormous progress, which has seen the noncoding RNAs (ncRNAs) turn from the so called dark matter RNA to critical functional molecules, influencing most physiological processes in development and disease contexts. Many ncRNAs interact with each other and are part of networks that influence the cell transcriptome and proteome and consequently the outcome of biological processes. The regulatory circuits controlled by ncRNAs have become increasingly more relevant in cancer. Further understanding of these complex network interactions and how ncRNAs are regulated, is paving the way for the identification of better therapeutic strategies in cancer

A microRNA feedback loop regulates global microRNA abundance during aging

Expression levels of many microRNAs (miRNAs) change during aging, notably declining globally in a number of organisms and tissues across taxa. However, little is known about the mechanisms or the biological relevance for this change. We investigated the network of genes that controls miRNA transcription and processing during C. elegans aging. We found that miRNA biogenesis genes are highly networked with transcription factors and aging-associated miRNAs. In particular, miR-71, known to influence life span and itself up-regulated during aging, represses alg-1/Argonaute expression post-transcriptionally during aging. Increased ALG-1 abundance in mir-71 loss-of-function mutants led to globally increased miRNA expression. Interestingly, these mutants demonstrated widespread mRNA expression dysregulation and diminished levels of variability both in gene expression and in overall life span. Thus, the progressive molecular decline often thought to be the result of accumulated damage over an organism's life may be partially explained by a miRNA-directed mechanism of age-associated decline.</jats:p

Assessment of the performance of the Chilbolton 3-GHz Advanced Meteorological radar for cloud-top height retrieval

The Chilbolton 3-GHz Advanced Meteorological Radar (CAMRa), which is mounted on a fully steerable 25 metre dish, can provide three-dimensional information on the presence of hydrometeors. We investigate the potential for this radar to make useful measurements of low-altitude liquid water cloud structure. In order to assess the cloud-height assignment capabilities of the 3-GHz radar, low-level cloud-top heights were retrieved from CAMRa measurements made between May and July 2003 and compared with cloud-top heights retrieved from a vertically pointing 94-GHz radar that operates alongside CAMRa. The average difference between 94-GHz and 3-GHz radar derived cloud-top heights is shown to be -0.1±0.4 km. In order to assess the capability of 3-GHz radar scans to be used for satellite-derived cloud-top height validation, Multi-angle Imaging SpectroRadiometer (MISR) cloud-top heights were compared with both 94-GHz and 3-GHz radar retrievals. The average difference between 94-GHz radar and MISR cloud-top heights is shown to be 0.1±0.3 km while the 3-GHz radar and MISR average cloud-top height difference is shown to be –0.2±0.6 km. In assessing the value of the CAMRa measurements, the problems associated with low reflectivity values from stratiform liquid water clouds, ground clutter, and Bragg scattering resulting from turbulent mixing are all addressed. We show that in spite of the difficulties, the potential exists for CAMRa measurements to contribute significantly to liquid water cloud-top height retrievals leading to the production of twodimensional transects (i.e. maps) of cloud-top height

Making Immigrants into Criminals: Legal Processes of Criminalization in the Post-IIRIRA Era

During a post-election TV interview that aired mid-November 2016, then President-Elect Donald Trump claimed that there are millions of so-called “criminal aliens” living in the United States: “What we are going to do is get the people that are criminal and have criminal records, gang members, drug dealers, we have a lot of these people, probably two million, it could be even three million, we are getting them out of our country or we are going to incarcerate.” This claim is a blatant misrepresentation of the facts. A recent report by the Migration Policy Institute suggests that just over 800,000 (or 7 percent) of the 11 million undocumented individuals in the United States have criminal records. Of this population, 300,000 individuals are felony offenders and 390,000 are serious misdemeanor offenders — tallies which exclude more than 93 percent of the resident undocumented population (Rosenblum 2015, 22-24).[1] Moreover, the Congressional Research Service found that 140,000 undocumented migrants — or slightly more than 1 percent of the undocumented population — are currently serving time in prison in the United States (Kandel 2016). The facts, therefore, are closer to what Doris Meissner, former Immigration and Naturalization Service (INS) Commissioner, argues: that the number of “criminal aliens” arrested as a percentage of all fugitive immigration cases is “modest” (Meissner et al. 2013, 102-03). The facts notwithstanding, President Trump’s fictional tally is important to consider because it conveys an intent to produce at least this many people who — through discourse and policy — can be criminalized and incarcerated or deported as “criminal aliens.” In this article, we critically review the literature on immigrant criminalization and trace the specific laws that first linked and then solidified the association between undocumented immigrants and criminality. To move beyond a legal, abstract context, we also draw on our quantitative and qualitative research to underscore ways immigrants experience criminalization in their family, school, and work lives. The first half of our analysis is focused on immigrant criminalization from the late 1980s through the Obama administration, with an emphasis on immigration enforcement practices first engineered in the 1990s. Most significant, we argue, are the 1996 Illegal Immigration Reform and Immigration Responsibility Act (IIRIRA) and the 1996 Antiterrorism and Effective Death Penalty Act (AEDPA). The second section of our analysis explores the social impacts of immigrant criminalization, as people’s experiences bring the consequences of immigrant criminalization most clearly into focus. We approach our analysis of the production of criminality of immigrants through the lens of legal violence (Menjivar and Abrego 2012), a concept designed to understand the immediate and long-term harmful effects that the immigration regime makes possible. Instead of narrowly focusing only on the physical injury of intentional acts to cause harm, this concept broadens the lens to include less visible sources of violence that reside in institutions and structures and without identifiable perpetrators or incidents to be tabulated. This violence comes from structures, laws, institutions, and practices that, similar to acts of physical violence, leave indelible marks on individuals and produce social suffering. In examining the effects of today’s ramped up immigration enforcement, we turn to this concept to capture the violence that this regime produces in the lives of immigrants. Immigrant criminalization has underpinned US immigration policy over the last several decades. The year 1996, in particular, was a signal year in the process of criminalizing immigrants. Having 20 years to trace the connections, it becomes evident that the policies of 1996 used the term “criminal alien” as a strategic sleight of hand. These laws established the concept of “criminal alienhood” that has slowly but purposefully redefined what it means to be unauthorized in the United States such that criminality and unauthorized status are too often considered synonymous (Ewing, Martínez, and Rumbaut 2015). Policies that followed in the 2000s, moreover, cast an increasingly wider net which continually re-determined who could be classified as a “criminal alien,” such that the term is now a mostly incoherent grab bag. Simultaneously and in contrast, the practices that produce “criminal aliens” are coherent insofar as they condition immigrant life in the United States in now predictable ways. This solidity allows us to turn in our conclusion to some thoughts about the likely future of US immigration policy and practice under President Trump. [1] These numbers are based on the assumption that “unauthorized immigrants and lawful noncitizens commit crimes at similar rates” (Rosenblum 2015, 22). However, there is research that provides good support that criminality among the undocumented is lower than for the foreign-born population overall (Rumbaut 2009; Ewing, Martínez, and Rumbaut 2015)

Design, characterization, and fabrication of solar-retroreflective cool-wall materials

Raising urban albedo increases the fraction of incident sunlight returned to outer space, cooling cities and their buildings. We evaluated the angular distribution of solar radiation incident on exterior walls in 17 U S. climates to develop performance parameters for solar-retroreflective walls, then applied first-principle physics and ray-tracing simulations to explore designs. Our analysis indicates that retroreflective walls must function at large incidence angles to reflect a substantial portion of summer sunlight, and that this will be difficult to attain with materials that rely on total internal reflection. Gonio-spectrophotometer measurements of the solar spectral bi-directional reflectivity of a bicycle reflector showed little to no retroreflection at large incidence angles. Visual comparisons of retroreflection to specular first-surface reflection for four different retroreflective safety films using violet and green lasers suggest their retroreflection to be no greater than 0.09 at incidence angles up to 45°, and no greater than 0.30 at incidence angles of up to 70°. Attempts to produce a two-surface retroreflector with orthogonal mirror grooves by cutting and polishing an aluminum block indicate that residual surface roughness impedes retroreflection. Ongoing efforts focus on forming orthogonal surfaces with aluminized Mylar film, a material with very high specular reflectance across the solar spectrum. We investigated (1) folding or stamping a free film; (2) adhering the film to a pre-shaped substrate; or (3) attaching the film to a flat ductile substrate, then shaping. The latter two methods were more successful but yielded imperfect right angles
