Mixed Effects Models for Recurrent Events Data with Partially Observed Time-Varying Covariates: Ecological Momentary Assessment of Smoking
Authors: Rathbun Stephen L. , Shiffman Saul 
Published: September 2015

SummaryCigarette smoking is a prototypical example of a recurrent event. The pattern of recurrent smoking events may depend on time-varying covariates including mood and environmental variables. Fixed effects and frailty models for recurrent events data assume that smokers have a common association with time-varying covariates. We develop a mixed effects version of a recurrent events model that may be used to describe variation among smokers in how they respond to those covariates, potentially leading to the development of individual-based smoking cessation therapies. Our method extends the modified EM algorithm of Steele (1996) for generalized mixed models to recurrent events data with partially observed time-varying covariates. It is offered as an alternative to the method of Rizopoulos, Verbeke, and Lesaffre (2009) who extended Steele's (1996) algorithm to a joint-model for the recurrent events data and time-varying covariates. Our approach does not require a model for the time-varying covariates, but instead assumes that the time-varying covariates are sampled according to a Poisson point process with known intensity. Our methods are well suited to data collected using Ecological Momentary Assessment (EMA), a method of data collection widely used in the behavioral sciences to collect data on emotional state and recurrent events in the every-day environments of study subjects using electronic devices such as Personal Digital Assistants (PDA) or smart phones.
Parsimonious Covariate Selection with Censored Outcomes
Authors: DiRienzo Albert Gregory 
Published: September 2015

Summary
A new objective methodology is proposed to select the parsimonious set of important covariates that are associated with a censored outcome variable Y; the method simplifies to accommodate uncensored outcomes. Covariate selection proceeds in an iterated forward manner and is controlled by the pre-chosen upper bound for the number of covariates to be selected and the global false selection rate and level. A sequence of working regression models for the event given a covariate set is fit among subjects not censored before y and the corresponding process (through y) of conditional prediction error estimated; the direction and magnitude of covariate effects can arbitrarily change with y. The newly proposed adequacy measure for the covariate set is the slope coefficient resulting from a regression (with no intercept) between the baseline prediction error process for the intercept-only model and that process corresponding to the covariate set. Under quite general conditions on the censoring variable, the methods are shown to asymptotically control the false selection rate at the nominal level while consistently ranking covariate sets which permits recruitment of all important covariates from those available with probability tending to 1. A simulation study confirms these analytical results and compares the proposed methods to recent competitors. Two real data illustrations are provided.
Innovation Policy for Grand Challenges. An Economic Geography Perspective
Authors: Coenen Lars , Hansen Teis , Rekers Josephine V. 
Published: September 2015

AbstractGrand challenges such as climate change, ageing societies and food security feature prominently on the agenda of policymakers at all scales, from the EU down to local and regional authorities. These are challenges that require the input and collaboration of a diverse set of societal stakeholders to combine different sources of knowledge in new and useful ways – a process that has occupied the minds of economic geographers looking at innovation in recent decades. Work in economic geography has in particular examined infrastructural, capability, network and institutional challenges that may be found in different types of regions. How can these insights improve researchers' and policymakers' understanding of the potential for innovation policies to address grand challenges? In this paper, we review these insights and then identify areas that push economic geographers to go beyond their previous focus and interests, notably by considering innovation policy in light of transformational rather than mere structural failures.
The Power Dynamics of Mandated Network Administrative Organizations
Authors: Saz‐Carranza Angel , Salvador Iborra Susanna , Albareda Adrià 
Published: September 2015

AbstractIn understanding what drives the development of network administrative organizations (NAOs) in mandated networks, power bargaining is central. The authors execute a comparative longitudinal case study of NAOs in two policy‐mandated networks. The article focuses specifically on the role of power in these developments and concludes that differences in NAO development arise from power dependencies, which are attributable in part to sector characteristics. It is proposed that mandated network members’ greater interdependence and greater dependence on external nonmembers, as well as whole network dependence on external actors, partly determine mandated networks’ NAO design. These networks will have larger and more capable NAOs (with more staff), accept sharing control of the NAO executive with the mandating party, and have broader responsibilities.
Efficient Coflow Scheduling Without Prior Knowledge
Authors: Chowdhury Mosharaf , Stoica Ion 
Published: September 2015

Inter-coflow scheduling improves application-level communication performance in data-parallel clusters. However, existing efficient schedulers require a priori coflow information and ignore cluster dynamics like pipelining, task failures, and speculative executions, which limit their applicability. Schedulers without prior knowledge compromise on performance to avoid head-of-line blocking. In this paper, we present Aalo that strikes a balance and efficiently schedules coflows without prior knowledge.
Aalo employs Discretized Coflow-Aware Least-Attained Service (D-CLAS) to separate coflows into a small number of priority queues based on how much they have already sent across the cluster. By performing prioritization across queues and by scheduling coflows in the FIFO order within each queue, Aalo's non-clairvoyant scheduler reduces coflow completion times while guaranteeing starvation freedom. EC2 deployments and trace-driven simulations show that communication stages complete 1.93X faster on average and 3.59X faster at the 95th percentile using Aalo in comparison to per-flow mechanisms. Aalo's performance is comparable to that of solutions using prior knowledge, and Aalo outperforms them in presence of cluster dynamics.
The role of IL‐33 and mast cells in allergy and inflammation
Authors: Saluja Rohit , Khan Mahejibin , Church Martin K. , Maurer Marcus 
Published: September 2015

AbstractInterleukin‐33 (IL‐33) is a member of the interleukin‐1 (IL‐1) cytokine family. It is preferentially and constitutively expressed in different structural cells such as epithelial cells, endothelial cells, and smooth muscle cells. During necrosis of these cells (after tissue injury or cell damage), the IL‐33 that is released may be recognized by different types of immune cells, such as eosinophils, basophils and, especially, mast cells. IL‐33 needs the specific receptor ST2 (membrane‐bound receptor) and Interleukin‐1 receptor accessory protein heterodimer for its binding, which instigates the production of different types of cytokines and chemokines that have crucial roles in the exacerbation of allergic diseases and inflammation. IL‐33 and mast cells have been influentially associated to the pathophysiology of allergic diseases and inflammation. IL‐33 is a crucial regulator of mast cell functions and might be an attractive therapeutic target for the treatment of allergic and inflammatory diseases. In this review, we summarize the current knowledge regarding the roles of IL‐33 and mast cells in the pathogenesis of allergies and inflammation.
Comparison of different approaches on example-based learning for novice and proficient learners

Published: September 2015

AbstractThis study examined the effectiveness of two example-based instructional procedures. One procedure examines the effect of example-problem pairs when they are simultaneously presented to a participant. The other procedure involved studying an example and then removing it and having the participant solve a similar problem. Participants were assigned randomly to two above procedures. Cognitive load
effects and learning outcomes were assessed. The results indicate that in the low prior knowledge group, learners who were simultaneously given examples and problems performed more effectively and efficiently, and reported significantly lower cognitive load than those who learned from example-problem pairs. In the high prior knowledge group, no significant difference was observed between the two procedures. This study provides empirical support for the process of learning from examples and problems simultaneously. It suggests that the effectiveness of certain instructional procedures in example-based learning depends upon the level of a learner’s prior knowledge.

Abstract

Background
The lizards of the family Agamidae are one of the most prominent elements of the Australian reptile fauna. Here, we present a genomic resource built on the basis of a wild-caught male ZZ central bearded dragon Pogona vitticeps.

Findings
The genomic sequence for P. vitticeps, generated on the Illumina HiSeq 2000 platform, comprised 317 Gbp (179X raw read depth) from 13 insert libraries ranging from 250 bp to 40 kbp. After filtering for low-quality and duplicated reads, 146 Gbp of data (83X) was available for assembly. Exceptionally high levels of heterozygosity (0.85 % of single nucleotide polymorphisms plus sequence insertions or deletions) complicated assembly; nevertheless, 96.4 % of reads mapped back to the assembled scaffolds, indicating that the assembly included most of the sequenced genome. Length of the assembly was 1.8 Gbp in 545,310 scaffolds (69,852 longer than 300 bp), the longest being 14.68 Mbp. N50 was 2.29 Mbp. Genes were annotated on the basis of de novo prediction, similarity to the green anole Anolis carolinensis, Gallus gallus and Homo sapiens proteins, and P. vitticeps transcriptome sequence assemblies, to yield 19,406 protein-coding genes in the assembly, 63 % of which had intact open reading frames. Our assembly captured 99 % (246 of 248) of core CEGMA genes, with 93 % (231) being complete.

Conclusions
The quality of the P. vitticeps assembly is comparable or superior to that of other published squamate genomes, and the annotated P. vitticeps genome can be accessed through a genome browser available at https://genomics.canberra.edu.au
Value systems and centrality of religiosity as predictors of non-religious and religious coping with stress in early adulthood.
Authors: Krok Dariusz 
Published: September 2015

Aim of the studyThe aim of the current study is to investigate whether values and the centrality of religiosity could be good predictors of non-religious and religious coping styles in early adulthood. Although previous research suggests that values and religious dimensions might be related to coping styles, their precise character remains unexplained.Subject or material and methodsResearch participants included 209 people (111 women and 98 men), randomly recruited in southern parts of Poland. Their ages ranged from 20 to 40 years, with a mean age of 28.4 years (SD = 6.44). All participants filled in the four questionnaires: The Scheler Values Scale, The Centrality of Religiosity Scale, The Coping Inventory for Stressful Situations, and The Brief RCOPE Scale.ResultsAesthetic, truth, and moral values were positively associated with task-oriented coping, while hedonic and vital values were positively linked to emotion-oriented and avoidance-oriented styles. As regards religious coping styles, vital, aesthetic, truth, and moral values were positively connected to positive coping. Negative coping was positively related to hedonic values, but negatively linked to sacred values. The centrality of religiosity dimensions were positively related to emotion-oriented coping, avoidance-oriented coping, social diversion, and positive religious coping.DiscussionValues and the centrality of religiosity dimensions turned out to be predictors for coping styles. The meanings made on a basis of important values and religious beliefs help individuals better understand the situation and find means of overcoming its negative consequences.ConclusionsValues and religiousness serve as a meaning system that enables individuals to interpret difficult events and effectively cope with distress caused by these events.

IntroductionAim of the study: The evaluation of the usefulness of the PSDRS in detecting affective disorders. Examination of the correlation of depressed mood states with cognitive disorders in patients at an early stage of cerebral stroke. Attempt at a comparison of the effectiveness of detecting depressive and cognitive disorders with the application of selected clinical scales.Material and MethodsThe examination included 43 patients within the first week after cerebral stroke. It was carried out with the application of two screening scales: Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA) and two scales for the evaluation of the degree of depressiveness: Post-stroke Depression Scale (PSDRS) and Beck Depression Inventory (BDI).ResultsA significant, negative correlation of the results of the PSDRS and MoCA scales was shown. Depressed moods in patients after cerebral stroke in a significant way statistically correlated with the disorders in the selected cognitive skills: visual and spatial functions, memory, attention functions and abstracting ability.ConclusionsThe PSDRS and MoCA scales proved to be more effective tools of the evaluation of depressive and cognitive disorders in patients at an early stage after cerebral stroke, than it was observed in the case of conventionally applied MMSE and BDI scales. The examination results additionally prove a significant dependence between mood and the efficiency of cognitive functions in this group of patients. With the weakening of cognitive functioning, also the patients’ mood became depressed.
Made-by-hand: [Re]valuing traditional (Japanese) textile practices for contemporary design
Authors: Parry-Williams Tim 
Published: September 2015

Abstract
Textiles touch all our lives – from the cradle to the grave – and serve increasingly diverse purposes. Historically, and as one of the first industrialized commodities, the skill and knowledge required to construct fabrics to clothe and furnish has dominated cultures worldwide. Contemporary Japanese textile design draws on countless traditions of often ancient but sustained craft practices. These traditions both respond to and employ the natural condition of things, exercising heightened and honed sensibilities to material know-how. Discussed through the discipline of woven textiles and, in particular, ‘traditional’ Japanese production systems, this article seeks to identify the location and distribution of both practical and aesthetic expertise in textile making and its transferable value for contemporary practices. The article presents case studies of surviving vernacular ‘cottage’ industries, where highly organized systems of knowledge exchange, spanning agricultural fibre production to direct technical instruction in thread making, ensure effective engagement with and ‘management’ of very specific materiality. The notion of intangible cultural property will be discussed in the context of inherited knowledge and how traditional social hierarchies and knowledge systems have served to nurture and perpetuate the sharing of skills and understanding through generations of textile makers and making.
Joining in and dropping out: Hand-stitching in spaces of social interaction
Authors: Shercliff Emma 
Published: September 2015

Abstract
The scale and pace of hand-stitching match those of the body, grounding cognitive and emotional experiences of solitude or sociality in a tangible process. The hand–eye–mind coordination required cultivates a distinctive form of attention to the self. On the one hand, as a private, contemplative activity, the slow rhythms of hand-stitching allow an individual to carve out time and space for introspective reflection. A collective stitching practice on the other hand, with fragmented tasks of short duration and frequent changes of colour, structures a very different space. In this article I draw on my experiences of joining an embroidery group to explore the simultaneity of social, cultural and physical processes in stitching practices, speech patterns and group dynamics. Finding that embodied knowledge of the craft includes patterns of social and physical interaction – or separation, I propose that hand-stitching practices can suggest alternative ways of thinking about how we create and occupy personal and social spaces.
Semper’s Jumper: Hard softness and soft hardness in archi-textile design
Authors: JeffEries Tom , JeffEries Tom 
Published: September 2015

Abstract
This article contributes to an ongoing interdisciplinary dialogue between architectural and textile/fashion design. Over the past decade architectural theory has re-engaged with the ideas proposed by Gottfried Semper in the 1850s to explore new definitions of how material practices can be understood and articulated, particularly that architecture can be seen as the concretization of textile form and pattern. The article discusses three iterations of the architectural column, introducing themes of scale, material language, constructional method and formal representation and brings together the body, space, structure, form and ornament. COLUMN 1 is a highly decorated concrete structural version, which is hard throughout, but suggests softness by its reference to textile (armature is sleeve). COLUMN 2 is essentially an architectural garment. It uses seamless purl and plain knitting with ribs at either end. It is a soft tactile textile covering to a hard base (armature and sleeve). COLUMN 3 moves away from visual ornament and explores the structural 3D form of knitted textile. The structure is entirely soft. This iteration opens up possibilities for architectural forms that explore the unique properties of seamless knitting, with its inherent strength and elasticity. There is the potential when the form is soft to challenge a perception that architecture is ‘fixed’ and to develop architectural forms that can, through post-construction processes or smart materiality, later become hard (sleeve is armature). The research brings together through practice architectural and textile/fashion references. Their further development through digital approaches, innovative materiality and construction opens up a craft/design dialogue and interdisciplinary discourse in the exploration and realization of novel textile-informed architecture.
Craft in unexpected places
Authors: Macbeth Penny , Barber Claire 
Published: September 2015

Abstract
Within the shifting territories of craft practice, the handmade has become a relational form of contemporary activity that transforms our understanding of place through a hands-on, minds-on process of collectivemaking. The conceptual significance of craft is activated through a chance encounter with the handmade in daily life. During the article we aim to explore the confluence between crafting, social engagement, volunteering and the realms of education and creative practice that we have both experienced first hand. What will be revealed will be the voices of practitioners collectively exploring cloth’s potential as a metaphor for consciousness, carrier of narrative and catalyst for community empathy and cohesion. This will be informed by an enquiry into historical forms of communal crafting drawn from archival research at the Imperial War Museum London and Foundling Hospital Collection housed at the Foundling Museum in London and a primary case study of the workshop ‘Desconocida – Unknown – Ukjent’. We employ a method used in object-based research: a value system that can be applied to the consideration of cloth as an object of study – namely, the locational, iconographical, archival, aesthetic and transferral. Focusing particularly on the transferral and locational, we will examine the significance of the handmade gesture in particular artistic, political and social contexts. These visual and textual narratives will inform our perception of ‘Craft in unexpected places’ and bring visibility to a selection of craft interventions by making links between the wide-reaching possibilities for craft-based practices and their expressive potential within the social and political landscapes they inhabit.
Redrawing craft: Archival sources and the mark in the work of artist Danica Maier
Authors: Renton Lucy 
Published: September 2015

Abstract
‘Stitch & Peacock’, the title of this recent exhibition by UK-based American artist Danica Maier, at The Collection and Usher Gallery, Lincoln, alludes equally to the craft, the imagery and the subversive messages hidden in her drawings for this show. The result of a seven month residency by Maier, the exhibition is the latest in a series of invitations to contemporary artists by curator Ashley Gallant to respond to objects held in the archives, as a means of presenting new perspectives on historic artefacts. Maier chose a Jacobean crewel work bedspread and a range of sixteenth- and seventeenth-century samplers, and by making work in response to these fragile objects, develops a dialogue that allows her to repeat and refract the textiles through the lens of drawing, and to make critical comparisons and equivalences between the stitch, the pixel and the drawn mark. Through her juxtapositions and reworkings, she asks us to reflect on the social context of the original female makers; to speculate on their potentially supressed frustrations, and their subversive power. Her wider drawing practice also critically invokes notions of labour, craft and technology, through her mining of a variety of archives.
