Statewide Administration of the CRAFFT Screening Tool: Highlighting the Spectrum of Substance Use

Background: Adolescent alcohol and drug use in the United States are associated with negative consequences spanning multiple domains. Much of the public health surveillance of these behaviors relies on self-report survey data. These data frequently takes the form of frequency or prevalence data for specific substances, which may not provide a complete picture of use. Objectives: This study analyzes a state-level survey that includes the CRAFFT screening tool. The study's goal is to elucidate the spectrum of substance use severity across a large segment of substance-using adolescents attending schools in the state of Indiana and to assess the contribution of a variety of predictor variables to the variance between users falling into each category of use severity. Methods: Data were collected in 2011 from 168,801 adolescents, of whom 25,204 met the inclusion criteria for this study. The authors utilize multinomial logit analyses to highlight variables, including sociodemographic data, poly-drug use, and risk/protective behavior scales, associated with each category of use. Results: Seriousness of use is not uniform across substance-using adolescents; 49% were categorized as nonproblem users, 33% as problem users, and 18% as dependent users. Risk and protective factors predict adolescents’ severity of substance use, but do not do so uniformly. Poly-drug use is a significant predictor of problem use and dependent use as well. Conclusions: The CRAFFT may provide a more nuanced perspective of adolescent substance use than frequency/prevalence data alone; the authors describe the implications derived from these data and analyses to the adolescent prevention and treatment systems.
Incremental learning of complex temporal patterns

A neural model for temporal pattern generation is used and analyzed for training with multiple complex sequences in a sequential manner. The network exhibits some degree of interference when new sequences are acquired. It is proven that the model is capable of incrementally learning a finite number of complex sequences. The model is then evaluated with a large set of highly correlated sequences. While the number of intact sequences increases linearly with the number of previously acquired sequences, the amount of retraining due to interference appears to be independent of the size of existing memory. The model is extended to include a chunking network which detects repeated subsequences between and within sequences. The chunking mechanism substantially reduces the amount of retraining in sequential training. Thus, the network investigated here constitutes an effective sequential memory. Various aspects of such a memory are discussed.
Relief mapping of non-height-field surface details

The ability to represent non-height-field mesostructure details is of great importance for rendering complex surface patterns, such as weave and multilayer structures. Currently, such representations are based on the use of 3D textures or large datasets of sampled data. While some of the 3D-texture-based approaches can achieve interactive performance, all these approaches require large amounts of memory. We present a technique for mapping non-height-field structures onto arbitrary polygonal models in real time, which has low memory requirements. It generalizes the notion of relief mapping to support multiple layers. This technique can be used to render realistic impostors of 3D objects that can be viewed from close proximity and from a wide angular range. Contrary to traditional impostors, these new one-polygon representations can be observed from both sides, producing correct parallax and views that are consistent with the observation of the 3D geometry they represent.
Quand une forme de travail en cache une autre. Le travail social n’est pas taylorisable

Les gestionnaires du social auraient reussi a tayloriser les services sociaux. L'analyse des pratiques permet de refuter cette proposition, car la relation observee entre le producteur et l'usager des services constitue un espace de creation d'informations qui sont, dans certains cas, reinvesties dans les rapports sociaux pour alimenter des interventions novatrices. Des parametres essentiels de la taylorisation n'ont pu etre verifies. Le rejet de la these de la taylorisation n'induit pas l'adhesion a des affirmations volontaristes qui attribuent aux praticiens une capacite generalisee d'echapper aux contraintes installees par des gestionnaires tentes par l'autoritarisme.
Change and continuity in a help-seeking problem gambling population: A five-year record *

This paper provides an overview of some trends among problem gamblers seeking help through the BreakEven/Gambler's Help problem gambling counselling services in Victoria, Australia, between July 1995 and June 2000. Data presented are drawn from details collected on clients at registration, assessment, and all other client contacts to form a Problem Gambling Services minimum data set (MDS). Analysis of the MDS shows a number of noteworthy trends towards continuity or change. A major element of continuity is the ability of the service to attract women, who constitute around 50% of the clients for the period. Major changes include the increasing trend towards presentation of clients at an earlier stage in their "career" as problem gamblers. Also identified is persistence or change in client characteristics, such as gender differences in gambling activity and problem type and level. In addition, a range of other factors are explored, such as level of debt and its associated characteristics, the characteristics of people committing crimes to finance their gambling, and the differences between people presenting for counselling and problem gamblers in the community.
Examining the role of inspiration in contemporary work organisations

The research presented in this thesis examines the role of inspiration in contemporary work organisations by exploring various meanings attributed to the term inspiration in organisational settings. This research is based on the interpretive philosophical paradigm concerned with understanding of the social world as it is at the level of subjective experience and utilises philosophical hermeneutics as a methodological approach of elucidating inspiration in organisational contexts; whereas philosophical hermeneutics emphasises the importance of conditions in which pre-understanding of inspiration evolves sufficiently to draw technical conceptions of inspiration in organisational settings. The material for developing a progressive understanding of inspiration has been provided by hermeneutic interviews carried out with volunteers at different levels of organisational hierarchy from three participating organisations to identify the various meanings of inspiration and their use, as well as gain a richer understanding how inspiration affects people at work. The findings stemming from participants' accounts were then used to conceptualise inspiration in organisational settings. The results of the study indicate that inspiration is significant to the context of contemporary work organisations and is often intentionally sought out at all organisational levels. The account on inspiration created in this study signifies that currently use of inspiration in organisational contexts lacks theoretical underpinning, wherein inspiration is often merely used in a flexible lexical way to add either clarity or ambiguity to any communication, depending on its context. Overall, having explored inspiration in organisational settings, this study has identified it as an emerging concept, which fundamentally exists and is recognised in contemporary work organisations. The developed conceptualisations of inspiration allow for the rethinking of various aspects of organisational contexts and leadership and motivation theory in particular. The theoretical underpinning for inspiration laid out in this study can be used as a basis for future research.
Anthriscifolcine A, a C18-diterpenoid alkaloid

The title compound, C26H39NO7, which was isolated from Delphinium anthriscifolium var. majus, has a lycoctonine carbon skeleton containing four six-membered rings (A, B, D and E) and three five-membered rings (C, F and G). Rings A, B and E adopt chair conformation, while ring D adopts a boat conformation. Rings C and F adopt envelope conformations.
Tunnel Vector: A New Routing Algorithm with Scalability

Routing algorithms such as Distance Vector and Link States have the routing table size as Omega (n), where n is the number of destination identifiers, thus providing only limited scalability for large networks when n is high. As the distributed hash table (DHT) techniques are extraordinarily scalable with n, our work aims at adapting a DHT approach to the design of a network- layer routing algorithm so that the average routing table size can be significantly reduced to O (log n) without losing much routing efficiency. Nonetheless, this scheme requires a major breakthrough to address some fundamental challenges. Specifically, unlike a DHT, a network-layer routing algorithm must (1) exchange its control messages without an underlying network, (2) handle link insertion/deletion and link-cost updates, and (3) provide routing efficiency. Thus, we are motivated to propose a new network-layer routing algorithm, Tunnel Vector (TV), using DHT-like multilevel routing without an underlying network. TV exchanges its control messages only via physical links and is self-configurable in response to linkage updates. In TV, the routing path of a packet is near optimal while the routing table size is O(log n) per node, with high probability. Thus, TV is suitable for routing in a very large network.
Geographers Count: A Report on Quantitative Methods in Geography

Abstract This report is drawn from a project funded to better support the teachers of quantitative methods in UK social science. In it we identify the types of quantitative methods taught in the geography curricula for UK schools and universities, and discuss attitudes towards those methods amongst students and teachers. We argue that geography has benefitted from its position at the intersection of the sciences, social sciences and humanities, retaining a quantitative component. Consequently, levels of basic numeracy and data handling have remained relatively high, leaving the discipline well placed to respond to the call for greater quantitative training within the social sciences in the UK. However, we also suspect that the typical levels of quantitative training in university human geography courses are not sufficiently high to compete on the international stage. As the title suggests, our report is focused on geography. However we raise issues germane to other disciplines including what actually we mean by quantitative methods, what should be taught in a twenty-first century curriculum, how to meaningfully embed those methods in the substantive themes and teaching of a discipline, and whether more should be expected as a minimum standard of quantitative competence than the existing Quality Assurance Agency benchmarks require.
Modeling Skip-Grams for Event Detection with Convolutional Neural Networks

Convolutional neural networks (CNN) have achieved the top performance for event detection due to their capacity to induce the underlying structures of the k -grams in the sentences. However, the current CNN-based event detectors only model the consecutive k -grams and ignore the non-consecutive k - grams that might involve important structures for event detection. In this work, we propose to improve the current CNN models for ED by introducing the non-consecutive convolution. Our systematic evaluation on both the general setting and the domain adaptation setting demonstrates the effectiveness of the non-consecutive CNN model, leading to the significant performance improvement over the current state-of-the-art systems.
WLC35-6: Relay-Assisted Spatial Multiplexing in Wireless Fixed Relay Networks

Fixed relays are expected to be a part of future infrastructure-based wireless networks. Besides coverage extension, such relays can form advanced architectures due to the flexibility in their power expenditure and physical size. This paper explores the potential benefits of multi-antenna relays for spatial multiplexing of independent data sources sending data to a common multi-antenna destination such as a base station or an access point. Overall, the system resembles a horizontally coded layered space-time architecture. In particular, we consider zero forcing decision feedback (ZF-DF) type MIMO receivers and study their outage performance under various (non-selective and selective) digital relaying protocols. For diversity relaying protocol, we propose two schemes, Joint ZF-DF and Parallel ZF-DF, for joint processing (combining and decoding) of the direct user signals and the signal from the relay. We show that with the proposed selective diversity relaying protocols and joint ZF-DF processing, the outage probability of the system can be decreased significantly.
The National Media and Things Genetic

Issues related to genetics and genetic technology have gained a great deal ofattention from researchers, policy makers, the press, and even some consumers. This article focuses on how one ofthese actors—the U.S. elite press—has developed a discourse around these issues. This discussion centers on the framing of articles, the sources used by reporters, and the differences between genetics as they relate to food and to medicine. Over 2,700 articles from the New York Times (1971-2001) and theWashington Post (1977-2001) have been analyzed. It is found that scientists and medical issues were much more likely to be framed as progressive than were articles on food or ones in which government officials were quoted. In addition, a more indepth analysis ofarticles pertaining to protests and demonstrations between 2000 and 2001 is presented.
A novel approach for high speed wireless pre-fall detection multisensory system

Enhancing the living standards of elderly people is important, and providing them with proper care at the time of emergency is necessary. Unintentional falls often result in an emergency situation for seniors. A novel approach based on efficient pre-fall detection is used to develop a system with smart wireless sensors that provide monitoring and protection for seniors and patients from a fall occurrence. This paper demonstrates an efficient, low cost and high speed sensory system for monitoring and detecting falls before occurring. The system is designed to fit in medical settings where communication between individual patients and control monitoring room is provided to enhance patient safety. The sensory network considers data collected from tri-axial accelerometers to detect and classify the type of fall that is about to happen. Pre-fall detection and classification is done through an integrated logic that constantly evaluates filtered acceleration data from the sensors and by calculating the tilt angle of the body. The fall decision suggested from the system will lead to deployment of a safety device to protect sensitive human body areas in elders such as hips, the brain, and the neck. The approach presented here was implemented with 10 subjects for several fall and normal activity scenarios. A Freescale ZSTAR3 system with wireless tri-axial accelerometers and ZigBee network (2.4GHZ) capability was used. Software was written to filter the white noise, while detecting the desirable “fall” signals, and making decision about the pre-fall detection and classification. The tilt angle and phase shift between the pulse wave (prior to the fall event) and the pulse magnitude were analyzed to diagnose the characteristics of the fall. The classification determined the direction of the fall occurrence. Results presented here show that this approach allows enough time for deployment of an integrated protection system.
The InfoPad Multimedia Terminal: A Portable Device for Wireless Information Access

The architecture of a device that is optimized for wireless information access and display of multimedia data is substantially different than configurations designed for portable stand-alone operation. The requirements to reduce the weight and energy consumption are the same, but the availability of the wireless link, which is needed for the information access, allows utilization of remote resources. A limiting case is when the only computation that is provided in the portable terminal supports the wireless links or the I/O interfaces, and it is this extreme position that is explored in the InfoPad terminal design. The architecture of the InfoPad terminal, therefore, can be viewed as essentially a switch which connects multimedia data sources in the supporting wired network to appropriate InfoPad output devices (e.g., video display), and connects InfoPad input devices to remote processing (e.g., speech recognizer server) in the backbone network.
FACILITATING INTEGRATED SERVICE DELIVERY VIA NETWORKING FORUMS: LESSONS FROM A CASE STUDY

At the dawn of democracy in South Africa in 1994 the government inherited a welfare system that was fragmented because of apartheid institutional arrangements. Collaboration between different government departments and organisations within civil society was almost non-existent. A silo culture was prevalent as a result of haphazard service delivery efforts, which led to ineffective and inefficient service delivery. Given the disjointed nature of service delivery within social welfare as well as other sectors of the economy, urgent measures were needed to ensure that the population benefits from well-coordinated and holistic service delivery efforts (White Paper for Social Welfare, 1997). It is in this context that the notion of integrated service delivery (ISD) became a national buzzword. There was political pressure for government departments as well as organisations within civil society to ensure that integration of services was promoted at all costs. As a part response to this call, the Department of Social Development (DSD) introduced the idea of networking forums. Several government departments and non-governmental organisations (NGOs) participate in these networking forums. Monthly meetings are held where stakeholders from different NGOs and government departments discuss and formulate coordinated responses to service delivery within particular geographical areas of operation. Thus, through these monthly meetings a platform for networking between NGOs, the DSD and other government departments is created which allows sharing of information and initiation of coordinated efforts in serving the communities within their demarcated radius of operation. This article examines how these networking forums pioneered by the DSD have been instrumental in enhancing integrated service delivery.
A new species of ladyfish, of the genus Elops (Elopiformes: Elopidae), from the western Atlantic Ocean

This paper describes Elops smithi, n. sp. , and designates a lectotype for E. saurus. These two species can be separated from the five other species of Elops by a combination of vertebrae and gillraker counts. Morphologically, they can be distinguished from each other only by myomere (larvae) or vertebrae (adults) counts. Elops smithi has 73–80 centra (total number of vertebrae), usually with 75–78 centra; E. saurus has 79–87 centra, usually with 81–85 centra. No other morphological character is known to separate E. smithi and E. saurus, but the sequence divergence in mtDNA cytochrome b (d = 0.023–0.029) between E. smithi and E. saurus is similar to or greater than that measured between recognized species of Elops in different ocean basins. Both species occur in the western Atlantic Ocean, principally allopatrically but with areas of sympatry, probably via larval dispersal of E. smithi by oceanographic currents.
Increased expression of h‐prune is associated with tumor progression and poor survival in gastric cancer

The human homolog of the Drosophila prune protein (from PRUNE, which encodes h‐prune), which interacts with glycogen synthase kinase 3, promotes cellular motility. H‐prune also interacts with nm23‐H1, a suppressor of cancer metastasis. It has been reported that stimulation of cellular motility by h‐prune is enhanced by its interaction with nm23‐H1 in breast cancer cells. In the present study, we examined the expression of h‐prune and nm23‐H1 during tumor progression in gastric cancer (GC). PRUNE mRNA was overexpressed in 12 (32%) of 38 GC cases by quantitative reverse transcription–polymerase chain reaction. PRUNE mRNA levels correlated significantly with advanced T grade, N grade and tumor stage. Immunohistochemical analysis revealed that 43 (30%) of 143 GC cases were positive for h‐prune, and h‐prune‐positive GC cases showed more advanced T grade, N grade and tumor stage than h‐prune‐negative GC cases. One hundred and twenty‐four (87%) of 143 GC cases were positive for nm23‐H1, and nm23‐H1 was expressed in almost all (42 cases, 98%) h‐prune‐positive GC cases. Many GC cases positive for both h‐prune and nm23‐H1 showed more advanced T grade, N grade and tumor stage than other type GC cases. Patients with h‐prune‐positive GC had a significantly worse survival rate than patients with h‐prune‐negative GC. These findings indicate that overexpression of h‐prune is associated with tumor progression and aggressiveness of GC. nm23‐H1 may enhance motility of cancer cells by interacting with h‐prune.

A Spatial Database Implementation for 3 D Computational Fluid Dynamics

In all domains of science, the size of data handled has reached up to an order of petabyte scale. In order to analyze and investigate a 3D computational fluid dynamics (CFD) dataset, in this work, a new system has been designed and implemented along with the traditional database management system. Multidimensional datasets require spatial operations such as spatial indices and spatial joins. The support for these operations is the key design goal. This system is specifically designed to support to handle CFD simulation datasets. Feature extractions and feature eliminations are the basic operations. The use cases show that this system can successfully process the operations. In addition, experimental results show reasonable performance.
ICT practices, social class and pedagogy in Swedish lower secondary schools

In Sweden, according to the present curriculum lower secondary schools are responsible for providing and tutoring all students in information and communication technology (ICT) as a tool in the search for knowledge and learning. In this article, it is proposed that schools have different preconditions to fulfil these obligations, depending upon how they integrate ICT into their pedagogical practices. The aim of this article is to examine the relationship among classrooms, ICT access, and pedagogy by comparing three Swedish lower secondary schools with different social compositions. The data consist of observations, interviews and policy documents. It is suggested that it is necessary to have sufficient equipment and strong pedagogy for all schools to fully use the potential of ICT as an educational, learning and teaching tool. It is concluded that the schools do not have equal opportunities to provide students with a pedagogical practice that can enable ICT skills and knowledge due to unique mandatorships and social acting spaces.
