An interpretative phenomenological analysis of prisoners’ experience of riotous behaviour in an adult male prison

Purpose – Prison violence generates much public interest with concerns for the financial costs, staff safety and public safety. The purpose of this paper is to explore the experience of riotous behaviour from the perspective of prisoners in a maximum secure adult prison. It also seeks gather information and to generate discussion on areas for future research. Design/methodology/approach – A purposive sampling method and in-depth semi-structured interviews were carried out. Interpretative phenomenological analysis identified super ordinate themes and related sub-themes within the participants’ narratives. Emergent themes were then considered in relation to the theories and concepts that underpinned and connected them. Findings – Super ordinate themes emerged centred around the subject of social processing and relationships. Prisoners emphasised the role of prisoner-staff relationships in feeling valued as part of the social structure and considered riotous behaviour the best method of communication at that.
Typologies of Children in Foster Care for Reasons Other than Abuse or Neglect

In Kansas, 45% of foster care placements occur for reasons besides child abuse or neglect. Yet little is known about their critical characteristics. By learning more about these cases, policies and practices can be tailored accordingly. This research utilized a statewide random sample (n = 254) of target children entering care in 2005. Two-step cluster analysis was used to generate typologies. Comparisons were made relative to child, parent/caretaker, and child welfare service variables. The analyses yielded five distinct clusters: infants, preschoolers, grade-schoolers, adolescents without prior abuse/neglect, and adolescents with a history of abuse/neglect. Our findings indicate that these cases represent a variety of individuals with different service needs, only a minority of whom fit the structures traditionally designed for abuse/neglect cases.
What do people expect from robots?

The study presented in this paper explores people perception of robots, with a particular focus on domestic use. We addressed issues related to positive and negative attitudes toward robots, needs for domestic robots as well as preferences in terms of appearance and interaction modalities. We used a combined qualitative and quantitative approach using interviews and questionnaires. In total, 240 people participated in our survey. Results indicate that a large proportion of participants have a very positive attitude towards robots. They expect concrete help for a variety of tasks from these devices. They prefer a small machine and they would like to interact with robots using speech.
“THERE'S NO SUCH THING AS A GAY HERO”

In comparing print media coverage of the Greg Louganis and Magic Johnson HIV-positive / AIDS announcements, there is strikingly different treatment of the two men. Specifically, the authors determined whether the athlete is framed as a hero, victim, or carrier with regard to his HIV-positive status. Johnson is unequivocally framed as a hero in the vast majority of articles. By contrast, Louganis almost never is framed solely as a hero and often is framed as being a carrier. The authors use the model of the confessional as developed by Foucault, combined with sin and redemption models presented by Payne and Mercuri and by Messner and Solomon, to analyze how media framings differ specifically by the sexual identities of the athletes. They argue that the dominant and accepted norms of sexuality are enforced and (re)produced by the media in this way.
Measurement of Response Sets

This report presents defensible procedures for measuring Acquiescence and Social Desirability along with scales to measure these variables. Such scales are only slightly related; each is related to both test and non-test behavior. Such scales should be useful: (1) as marker variables in personality research, (2) as “response set” controls when studying the predictive validity of content variance of inventories, and (3) as measures of reliable characteristics of individuals.
The scopolamine model of dementia: determination of central cholinomimetic effects of physostigmine on cognition and biochemical markers in man

Administration of the muscarinic antagonist scopolamine has been proposed as a pharmacological model for Alzheimer's disease. We have attempted to characterize the cognitive deficits produced by the administration of scopolamine (0.2 and 0.4 mg intra muscularly) to normal volunteers. We have also demonstrated reversal of these deficits by the cholinesterase inhibitor physostigmine (1.2 mg intramuscularly). Physostigmine also elevated subjects' plasma ACTH levels, a marker of central cholinergic activity. In the cognitive study, we found that scopolamine impaired subjects' performance on verbal learning, spatial learning and choice reaction time. These changes were associated with subjective sedation as measured by analogue rating scales. Physostigmine attenuated the impairment in verbal learning and reduced subjective sedation. In the biochemical study we examined the effects of the same drug regimes on plasma ACTH levels. Physostigmine administered with a peripherally active cholinergic antagonist (glycopyrrolate 0.2 mg intramuscularly) produced a rise in ACTH level which reached a peak 30 min after drug administration. Such a rise was not apparent when the physostigmine was coadministered with scopolamine. These results suggest that cognitive and neuroendocrine indices of central cholinergic activity such as these may be useful in determining the effectiveness of potential new therapeutic agents for Alzheimer's disease.
How African American Adolescents Manage Depression

BACKGROUND: African American (AA) adolescents with depression face serious negative outcomes. Despite racial/ethnic disparities in treatment utilization, few studies have explored how AA adolescents manage their depression. OBJECTIVE: To describe common ways AA adolescents manage depressive symptoms through relationships with people in their lives. DESIGN: Qualitative descriptive methods were used to analyze the narratives of 22 AA young adults who had been depressed as adolescents and 5 AA adolescents in treatment for depression. RESULTS: A typology describing the varied ways AA adolescents manage their depressive symptoms through interactions with other people was constructed and labeled Being With Others. The five categories in the typology are keeping others at bay, striking out at others, seeking help from others, joining in with others, and having others reach out. CONCLUSIONS: Clinicians might use the Being With Others typology to guide discussions related to detecting, assessing, and treating AA adolescents with depression.
Design and performance of a Ku-band 6-bit MMIC phase-shifter

This paper describes design consideration and performance of a Ku-band monolithic phase shifter utilizing 0.25-¿m PHEMT switches. The developed 6-bit phase shifter demonstrates an overall phase deviation less than 1.5 rms and an insertion loss variation less than 0.35 dB rms from 12 to 15 GHz. For all 64 states, the insertion loss is measured to be 9 dB and the VSWR is less than 1.4. The chip size of the monolithic phase shifter is 3.1 mm × 1 mm.
Further Support for Responsibility in Different Obsessive-Compulsive Symptoms in Turkish Adolescents and Young Adults

Abstract According to the cognitive model, an inflated sense of responsibility is an important cognitive mediator both in the development and maintenance of obsessive-compulsive disorder (OCD). Empirical findings assign differential roles to responsibility in different kinds of obsessive-compulsive (OC) symptoms. However, findings that suggested a different function for responsibility revealed the need for an operational definition of responsibility and its multi-factorial structure. Few studies have examined the role of responsibility in OC symptoms in adolescents. The present study therefore aimed to explore responsibility concerns and to evaluate the relationship between responsibility dimensions and obsessive-compulsive symptom subgroups in two samples of adolescents and university students in a developing non-Western country. The findings suggested that the Responsibility Attitude Scale had a bifactorial structure, responsibility being based on self-dangerousness and prevention. Adolescents reported more responsibility in prevention and self-dangerousness than university students. The results appear to contribute to the symptom differentiation of OC behaviour by highlighting the importance of both dimensions of responsibility for checking symptoms, responsibility based on danger prevention for cleaning and, finally, responsibility based on self-dangerousness for obsessive thinking. Replication with clinical samples and different methodologies are encouraged.
Meanings of Aboriginal gambling across New South Wales, Australia

A social perspective of gambling explains gambling as a consequence of the social, structural and cultural environment in which gamblers live. In the Australian Indigenous context the social perspective is important, given the significance of community and family ties. This paper aims to explore meanings of Aboriginal gambling across New South Wales (NSW), Australia. Taking an interpretivist stance, semi-structured interviews were conducted with 13 knowledgeable Indigenous Australians, key elected and nominated state representatives. Meanings of Aboriginal gambling included the collective activity of gambling within social networks in the hope of a win. More problematic meanings of gambling were always gambling to win, chasing losses and continual financial distress which appeared to reduce social network bonds. Contrasting problem gambling with recreational gambling revealed that some Indigenous gamblers use their existing cultural and kin relationships on which many of their social networks are based to gamble together in a controlled recreational manner.
Comments on "modeling TCP reno performance: a simple model and its empirical validation"

In this Comments, several errors in Padhye et al., 2000, are pointed out. The more serious of these errors result in an over prediction of the send rate. The expression obtained for send rate in this Comments leads to greater accuracy when compared with the measurement data than the original send rate expression in Padhye et al.
Third-Order Tensors as Operators on Matrices: A Theoretical and Computational Framework with Applications in Imaging

Recent work by Kilmer and Martin [Linear Algebra Appl. , 435 (2011), pp. 641--658] and Braman [Linear Algebra Appl. , 433 (2010), pp. 1241--1253] provides a setting in which the familiar tools of linear algebra can be extended to better understand third-order tensors. Continuing along this vein, this paper investigates further implications including (1) a bilinear operator on the matrices which is nearly an inner product and which leads to definitions for length of matrices, angle between two matrices, and orthogonality of matrices, and (2) the use of t-linear combinations to characterize the range and kernel of a mapping defined by a third-order tensor and the t-product and the quantification of the dimensions of those sets. These theoretical results lead to the study of orthogonal projections as well as an effective Gram--Schmidt process for producing an orthogonal basis of matrices. The theoretical framework also leads us to consider the notion of tensor polynomials and their relation to tensor eigentupl.
Dissociation and Meditation

ABSTRCT The purpose of the current paper is to compare meditational and dissociative states in terms of their effects on consciousness, attention, affect, cognition, identity, and pain sensitivity. To illustrate these dimensions of dissociation, a case example is presented of a veteran with combat-related posttraumatic stress disorder who had particularly severe dissociation symptoms. The Classical Yoga literature is reviewed to examine these dimensions as they pertain to meditational states. Although dissociative and meditational states can involve alterations in consciousness, attention, affect, cognition, identity, and pain sensitivity, the nature of changes in these two states is distinct. Applications of meditation in treatment contexts have made use of some of the powerful techniques for attention control but do not incorporate the full range of practices because of the secular setting of treatment and the goal of symptom relief. The use of meditation as a treatment for dissociation has not been systematically evaluated.
Measuring quality of life in aphasia: Results from two scales

Background: Although aphasia affects quality of life (QoL), the impact within specific domains (e.g., psychosocial, communication) is poorly understood. Moreover, the complex and multidimensional nature of QoL renders it difficult to measure accurately using a single global scale. Aims: Using two recently developed QoL scales, the Stroke and Aphasia Quality of Life Scale‐39, (SAQOL; Hilari, Byng, Lamping, & Smith, 2003a) and the American Speech Language Hearing Association's Quality of Communication Life Scale (QCL; Paul et al., 2004), this study aimed to document the domains of QoL that were most affected for participants with aphasia compared to control participants, as well as to determine the relationship between the two scales, their sub‐domains, and linguistic variables in aphasia. Methods & Procedures: The two scales were administered to a group of 19 participants with aphasia (14 male, 5 female), ages ranging from 27 to 79 years, and 19 age‐ and gender‐matched control participants. Various types and severity of aphasia were represented in the aphasia group. The performances of aphasia and control groups were compared, and correlation analyses examined the relationship between the two scales and their sub‐domains in the aphasia group only. Outcomes & Results: Compared to control participants, QoL was lower in participants with aphasia, with the communication sub‐domain of SAQOL and socialisation/activities sub‐domain of QCL being the most affected areas of functioning. Between the two scales, the communication sub‐domain of SAQOL correlated with the socialisation/activities sub‐domain and the QCL mean. Moreover, linguistic variables correlated strongly with psychosocial, communication and socialisation/activities sub‐domains of QoL. Conclusions: Measuring QoL using the SAQOL and the QCL captures different but equally important aspects of experiences of living with aphasia. When interpreted together, they provide a holistic picture of functioning in aphasia that includes broad overviews of QoL from the SAQOL and a finer‐grained analysis of communication impairments on QoL from the QCL.
‘Greenwich Observatory Time for the public benefit’: standard time and Victorian networks of regulation

Abstract The widespread adoption of standard time in Britain took more than fifty years and simple public access to a representation of it took longer still. Whilst the railways and telegraph networks were crucial in the development of standardized time and time-distribution networks, very different contexts existed, from the Victorian period onwards, where time was significant in both its definition and its distribution. The moral drive to regulate and standardize aspects of daily life, from factory work to the sale of liquor, led to time being used as a tool for control. Yet, as a tool, it was problematic, both in its own regulation and in the regulation of its distribution. Companies such as the Standard Time Company, in creating businesses out of time distribution, found themselves at the heart of discussions of time and standards, acting, as they did, as a nexus between the nation's master timekeeper, the Royal Observatory, and London public houses, Lancashire cotton mills and myriad small businesses. We can see this network both literally, in electric wires, clocks, batteries and relays, and metaphorically, transmitting Victorian moral concerns of ‘power’ and ‘intelligence’ between imperial state and individual. Naturally enough, the network itself was as contested as the message it transmitted.
Mobile Charging in Wireless-Powered Sensor Networks: Optimal Scheduling and Experimental Implementation

Wireless radio frequency (RF) energy transfer is a promising technology to provide a reliability-guaranteed power supply for wireless sensor networks. In this paper, we consider a special wireless-powered sensor network consisting of a mobile energy station that can travel through a preplanned path to charge wireless-powered sensors located in the considered area. We develop a hardware platform using off-the-shelf RF energy transfer hardware equipment to evaluate the practical performance of wireless sensor networks powered by RF energy transfer. We establish an empirical model based on our developed platform and use the empirical model to jointly optimize path planning and mobile charge scheduling for wireless-powered sensor networks. We derive the optimal policy for the mobile energy station to optimize its decisions about the path that it will travel and the subset of sensors to charge during each time period. Numerical results show that our derived policy significantly improves the performance of wireless sensor networks in different practical scenarios.
A haptic shared control algorithm for flexible human assistance to semi-autonomous robots

Autonomous as well as teleoperated robots find wide applications in various environments. Their capability to accomplish complex and dynamic operations can be significantly improved by fusing human intelligence with autonomous algorithms. In this paper, we propose a haptic shared control algorithm to provide flexible human assistance for semi-autonomous mobile robots. Through the admittance and impedance models, the haptic shared controller smoothly puts together human operator inputs with robot autonomy. Further, the level of autonomy is fully determined by the operator with the grasp motion. A decomposed design has been taken for the autonomous controller of the mobile robot. The algorithm was implemented on the haptic interface omega.7 together with a QBot mobile robot, and its feasibility and efficacy have been validated by experiments.
Vertex isoperimetric parameter of a Computation Graph

Let G = (V,E) be a computation graph, which is a directed graph representing a straight line computation and S ⊂ V. We say a vertex v is an input vertex for S if there is an edge (v, u) such that v ∉ S and u ∈ S. We say a vertex u is an output vertex for S if there is an edge (u, v) such that u ∈ S and v ∉ S. A vertex is called a boundary vertex for a set S if it is either an input vertex or an output vertex for S. We consider the problem of determining the minimum value of boundary size of S over all sets of size M in an infinite directed grid. This problem is related to the vertex isoperimetric parameter of a graph, and is motivated by the need for deriving a lower bound for memory traffic for a computation graph representing a financial application. We first extend the notion of vertex isoperimetric parameter for undirected graphs to computation graphs, and then provide a complete solution for this problem for all M. In particular, we show that a set S of size M = 3k2 + 3k + 1 vertices of an infinite directed grid, the boundary size must be at least 6k + 3, and this is obtained when the vertices in S are arranged in a regular hexagonal shape with side k + 1.
Recent advances in autonomic provisioning of big data applications on clouds

Cloud computing assembles large networks of virtualised ICT services such as hardware resources (such as CPU, storage, and network), software resources (such as databases, application servers, and web servers) and applications. Big Data applications have become a common phenomenon in domain of science, engineering, and commerce. Large-scale, heterogeneous, and uncertain Big Data applications are becoming increasingly common, yet current cloud resource provisioning methods do not scale well and nor do they perform well under highly unpredictable conditions (data volume, data variety, data arrival rate, etc.). Much research effort have been paid in the fundamental understanding, technologies, and concepts related to autonomic provisioning of cloud resources for Big Data applications, to make cloud-hosted Big Data applications operate more efficiently, with reduced financial and environmental costs, reduced under-utilisation of resources, and better performance at times of unpredictable workload. Targeting the aforementioned research challenges, this special issue compiles recent advances in Autonomic Provisioning of Big Data Applications on Clouds. The special issue articles are briefly summarized.
Regional quantification of left atrial early diastolic strain in two groups of patients with mitral stenosis: normal sinus rhythm vs atrial fibrillation

Strain rate imaging (SRI) is proposed for assessing atrial function. There are limited studies on the role of SRI in assessing the left atrial (LA) function in patients with mitral stenosis (MS). We decided to assess LA early diastolic strain to evaluate LA conduit function in two groups of patients with MS.
Neuronal cell adhesion molecules and cytotactin are colocalized at the node of Ranvier

Immunocytochemical methods were used to show that Ng-CAM (the neuron- glia cell adhesion molecule), N-CAM (the neural cell adhesion molecule), and the extracellular matrix protein cytotactin are highly concentrated at nodes of Ranvier of the adult chicken and mouse. In contrast, unmyelinated axonal fibers were uniformly stained by specific antibodies to both CAMs but not by antibodies to cytotactin. Ultrastructural immunogold techniques indicated that both N-CAM and Ng- CAM were enriched in the nodal axoplasm and axolemma of myelinated fibers as well as within the nodal regions of the myelinating Schwann cell. At embryonic day 14, before myelination had occurred, small- caliber fibers of chick embryos showed periodic coincident accumulations of the two CAMs but not of cytotactin, with faint labeling in the axonal regions between accumulations. Cytotactin was found on Schwann cells and in connective tissue. By embryonic day 18, nodal accumulations of CAMs were first observed in a few medium- and large-caliber fibers. Immunoblot analyses indicated that embryonic to adult conversion of N-CAM and a progressive decrease in the amount of Ng-CAM and N-CAM occurred while nodes were forming. Sciatic nerves of mouse mutants with defects in cell interactions showed abnormalities in the distribution patterns and amount of Ng-CAM, N-CAM, and cytotactin that were consistent with the known morphological nodal disorders. In trembler (+/Tr), intense staining for both CAMs appeared all along the fibers and the amounts of N-CAM in the sciatic nerve were found to be increased. In mice with motor endplate disease (med/med), Ng-CAM and N- CAM, but not cytotactin, were localized in the widened nodes. Both trembler and med/med Schwann cells stained intensely for cytotactin, in contrast to normal Schwann cells which stained only slightly. All of these findings are consistent with the hypothesis that surface modulation of neuronal CAMs mediated by signals shared between neurons and glia may be necessary for establishing and maintaining the nodes of Ranvier.
