How police officers in England and Wales learn to construct and report 'official reality'

This research examines the way police officers learn to make sense of, and report, 'official reality'. 100 in-depth, tape recorded interviews were carried out with police officers at various stages of service including probationers, Tutor Constables, Trainers and a group of experienced officers. Full transcripts of the interviews were prepared and then subjected to a close-grained, qualitative analysis in which various themes were identified. The results were then subjected to a statistical technique known as logistic regression. The findings reveal, inter alia, that an officer's interpretation of incidents will change with experience. Probationers at first treat incidents as self-contained legal 'texts' with semiosis limited to consideration of 'points to prove'. Later they begin to take into consideration contextual factors. More experienced officers introduce experiential or 'intertextual' factors into their semiosic activity so that their interpretation includes not just synchronic but diachronic elements. Various 'interpretive communities' are identified linked to structural groupings within the policing institution and impacting on the way incidents are interpreted and reported. Police culture[s] is shown to largely determine what elements of an incident are seen as salient and what are ignored. Officers develop socio-spatial cognitive frameworks during their Tutor Constable attachments made up of detailed local knowledge and historical practices which shape the way they approach incidents, and interact with the public. The substantive criminal law was found to offer little guidance to patrol officers who utilise normative and evaluative conceptual frameworks grounded in personal and family value systems. Law is used by police officers to legitimise decisions arrived at through a parallel process of decision-making that is grounded in police operational culture.

The present findings support a social constructionist theory of the semiotic encounter in which the patrol officer is not a passive observer of events, but constructs a version of 'reality' from various potential interpretations.
Improving Student Comprehension Skills through the Use of Reading Strategies.

This study describes a program designed to increase student academic performance through the use of reading strategies. The targeted population consists of third and fourth grade students in three separate communities located in northern Illinois. All three communities are part of one major metropolitan area, and the status of family income ranges from low to middle levels. Although students continually meet state standards in reading, there is an expectation by district administrators that the students should be reading at higher levels. Evidence that there is room for improvement in this area includes state assessment, comprehension testing, and teacher observation. Analysis of probable cause data reveals that lack of phonetic/decoding skills and vocabulary, curricular changes, lack of parental involvement, minimal prior knowledge, increased bilingual population, developmental difficulties, low self-esteem, and a decreased value of literacy in the home results in low reading skills. Inconsistencies in teacher training and the selection of activities in the reading curriculum contribute to deficiencies in student reading. A review of the solution strategies suggested by the professional literature, combined with an analysis of the settings resulted in the following interventions: teacher training, introduction of reading strategies, monitoring student progress, and the practice of guided reading. Results indicated that the majority of the targeted students revealed an improvement in their ability to comprehend text. Appendixes contain numerous charts of standardized test scores; entrance and exit interview questions; a checklist; the teacher survey; and consent fnrmq.

Comprehensive Transcriptome Profiling Reveals Long Noncoding RNA Expression and Alternative Splicing Regulation during Fruit Development and Ripening in Kiwifruit (Actinidia chinensis)

Genomic and transcriptomic data on kiwifruit (Actinidia chinensis) in public databases are very limited despite its nutritional and economic value. Previously, we have constructed and sequenced nine fruit RNA-Seq libraries of A. chinensis “Hongyang” at immature, mature, and postharvest ripening stages of fruit development, and generated over 66.2 million paired-end and 24.4 million single-end reads. From this dataset, here we have identified 7051 long noncoding RNAs (lncRNAs), 29,327 alternative splicing (AS) events and 2980 novel protein-coding genes that were not annotated in the draft genome of “Hongyang. ” AS events were demonstrated in genes involved in the synthesis of nutritional metabolites in fruit, such as ascorbic acids, carotenoids, anthocyanins, and chlorophylls, and also in genes in the ethylene signaling pathway, which plays an indispensable role in fruit ripening. Additionally, transcriptome profiles and the contents of sugars, organic and main amino acids were compared between immature, mature, and postharvest ripening stages in kiwifruits. A total of 5931 differentially expressed genes were identified, including those associated with the metabolism of sugar, organic acid, and main amino acids. The data generated in this study provide a foundation for further studies of fruit development and ripening in kiwifruit, and identify candidate genes and regulatory elements that could serve as targets for improving important agronomic traits through marker assisted breeding and biotechnology.
The implications of emotional security theory for understanding and treating childhood psychopathology

Understanding why interparental difficulties pose a risk to children in families experiencing domestic violence is an urgent task for ameliorating childhood psychopathology, particularly in light of the paucity of knowledge on the unfolding mediating mechanisms and the potentiating and protective conditions that underlie the multiplicity of pathways between domestic violence and child maladjustment. Toward addressing this significant gap, this paper examines how the emotional security theory (EST) may foster advances in our understanding of the genesis, course, and treatment of children's psychological problems in families experiencing domestic violence. Following an overview of the theoretical assumptions and significance of translating the emotional security theory to high-risk contexts, we address how children's difficulties in preserving security may emerge in the face of domestic violence and accompanying forms of severe family adversity, and illustrate the implications of emotional insecurity for childhood psychopathology in homes characterized by domestic violences. In the final section, we address how the EST may be useful in informing public policy and intervention initiatives designed to reduce the burden of mental illness.This research was supported by a National Institute of Mental Health award (R01 MH071256) to Patrick T.

Comparative evaluation of the effects of different photoablative laser irradiation protocols on the gingiva of periodontopathic patients.

OBJECTIVE We aimed at quantifying the presence of periodontopathogens in gingival biopsies from periodontitis patients treated with different photoablative lasers (diode GaAs, Er:YAG, Nd:YAG, and CO(2) lasers) and histologically analyzing their effects on the gingiva. BACKGROUND DATA Substantial evidence indicates that intracellular location of periodontal bacteria in the gingival epithelium may contribute to chronic periodontitis. METHODS Sixteen adult subjects with chronic periodontitis were subjected to conventional scaling/root planing and topical chlorhexidine, and immediately laser-irradiated on the inner and outer free gingiva. Small gingival biopsies were subjected to real-time polymerase chain reaction and cytofluorescence to identify periodontopathogens; tissue damage and endothelial ICAM-1 expression were assessed by histological and immunofluorescence analyses. RESULTS High DNA levels of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Treponema denticola, Prevotella intermedia, and Ekenella corrodens, were detected in all samples. Nd:YAG and diode lasers were capable of eradicating periodontopathogenic bacteria endowed within gingival epithelial cells outside periodontal pockets, without causing connective tissue damage and microvessel rupture. They also reduced ICAM-1 immunolabelling by the vascular endothelium. Conversely, Er:YAG lasers induced marked microvessel rupture and bleeding and failed to completely and selectively ablate the infected gingival epithelium, whereas CO(2) laser caused heat-induced coagulation of the lamina propria. CONCLUSIONS This study indicates that periodontopathogens can persist within cells outside the pocket epithelium, despite conventional periodontal treatment. Nd:YAG and diode lasers are able to eradicate intra- and extracellular bacteria from these sites, suggesting that they can be considered suitable devices to improve the clinical outcome of periodontal disease.
Quantitative morphometrical characterization of human pronuclear zygotes.

BACKGROUND Identification of embryos with high implantation potential remains a challenge in in vitro fertilization (IVF). Subjective pronuclear (PN) zygote scoring systems have been developed for that purpose. The aim of this work was to provide a software tool that enables objective measuring of morphological characteristics of the human PN zygote. METHODS A computer program was created to analyse zygote images semi-automatically, providing precise morphological measurements. The accuracy of this approach was first validated by comparing zygotes from two different IVF centres with computer-assisted measurements or subjective scoring. Computer-assisted measurement and subjective scoring were then compared for their ability to classify zygotes with high and low implantation probability by using a linear discriminant analysis. RESULTS Zygote images coming from the two IVF centres were analysed with the software, resulting in a series of precise measurements of 24 variables. Using subjective scoring, the cytoplasmic halo was the only feature which was significantly different between the two IVF centres. Computer-assisted measurements revealed significant differences between centres in PN centring, PN proximity, cytoplasmic halo and features related to nucleolar precursor bodies distribution. The zygote classification error achieved with the computer-assisted measurements (0.363) was slightly inferior to that of the subjective ones (0.393). CONCLUSIONS A precise and objective characterization of the morphology of human PN zygotes can be achieved by the use of an advanced image analysis tool. This computer-assisted analysis allows for a better morphological characterization of human zygotes and can be used for classification.
Cognitive Team Diversity and Individual Team Member Creativity: A Cross-Level Interaction

We theorized and tested the conditions under which cognitive team diversity is positively related to individual team member creativity. Hierarchical linear modeling results using 316 employees on 68 teams from Chinese companies indicated that a team member’s creative self-efficacy moderated the relationship between cognitive team diversity and individual creativity: this relationship was positive only when creative self-efficacy was high. Further, “transformational leadership” moderated the relationship in such a way that cognitive team diversity was positively related to individual creativity only when transformational leadership was high.
Working Memory Encoding Delays Top–Down Attention to Visual Cortex

The encoding of information from one event into working memory can delay high-level, central decision-making processes for subsequent events [e.g., Jolicoeur, P., & Dell'Acqua, R. The demonstration of short-term consolidation. Cognitive Psychology, 36, 138–202, 1998, doi:10.1006/cogp.1998. 0684]. Working memory, however, is also believed to interfere with the deployment of top–down attention [de Fockert, J. W. , Rees, G. , Frith, C. D. , & Lavie, N. The role of working memory in visual selective attention. Science, 291, 1803–1806, 2001, doi:10.1126/science.1056496]. It is, therefore, possible that, in addition to delaying central processes, the engagement of working memory encoding (WME) also postpones perceptual processing as well. Here, we tested this hypothesis with time-resolved fMRI by assessing whether WME serially postpones the action of top–down attention on low-level sensory signals. In three experiments, participants viewed a skeletal rapid serial visual presentation sequence that contained two target items (T1 and T2) separated by either a short (550 msec) or long (1450 msec) SOA. During single-target runs, participants attended and responded only to T1, whereas in dual-target runs, participants attended and responded to both targets. To determine whether T1 processing delayed top–down attentional enhancement of T2, we examined T2 BOLD response in visual cortex by subtracting the single-task waveforms from the dual-task waveforms for each SOA. When the WME demands of T1 were high (Experiments 1 and 3), T2 BOLD response was delayed at the short SOA relative to the long SOA. This was not the case when T1 encoding demands were low (Experiment 2). We conclude that encoding of a stimulus into working memory delays the deployment of attention to subsequent target representations in visual cortex.
Context-theoretic Semantics for Natural Language: an Overview

We present the context-theoretic framework, which provides a set of rules for the nature of composition of meaning based on the philosophy of meaning as context. Principally, in the framework the composition of the meaning of words can be represented as multiplication of their representative vectors, where multiplication is distributive with respect to the vector space. We discuss the applicability of the framework to a range of techniques in natural language processing, including subsequence matching, the lexical entailment model of Dagan et al. (2005), vector-based representations of taxonomies, statistical parsing and the representation of uncertainty in logical semantics.
Organic acids and iron translocation in maize genotypes.

Translocation of Fe was studied in WF9 (Fe-efficient) and ys(1)/ys(1) (Fe-inefficient) maize (Zea mays L.) genotypes. Iron-deficient WF9 translocated more Fe to the tops than Fe-deficient ys(1)/ys(1). Malate and citrate contents of root saps increased nearly 2-fold and aconitate increased over 4-fold in both genotypes as Fe of nutrient solutions increased from 0.1 to 3 milligrams per liter. Relative acid contents in root saps were as follows: malate > aconitate > citrate. Citric acid concentrations in stem exudates were nearly the same as in root sap. Malic acid concentrations were considerably lower in exudates than in root saps, and only a trace of aconitic acid was detected in the exudates. The concentration of Fe was 7-fold higher in exudate of WF9 than in exudate of ys(1)/ys(1) and the concentration of exudate P was about the same for both genotypes.Electropherograms of WF9 stem exudates showed that (59)Fe moved toward the anode as (59)Fe-citrate. Exudates of ys(1)/ys(1) contained insufficient (59)Fe to produce radiographs. When (59)Fe was added in vitro to ys(1)/ys(1) stem exudate, the (59)Fe moved as (59)Fe-citrate, indicating that sufficient citric acid was present in the exudate to chelate the Fe. Effectiveness of citric, isocitric, trans-aconitic, and malic acids in moving (59)Fe electrophoretically in acetate, citrate, isocitrate, trans-aconitate, and malate buffers was studied. Malic, acetic, and trans-aconitic acids were ineffective in moving Fe from the origin. Citric acid moved Fe anodically whenever present on the electropherogram and successfully competed with the other acids for Fe.Results with ys(1)/ys(1) roots indicate an absence of an efficient mechanism for transporting Fe from cortical cells to the xylem. If Fe can reach the xylem stream, the ys(1)/ys(1) genotype should be as efficient as WF9 in moving Fe to the leaves.
Alternating Projections and Douglas-Rachford for Sparse Affine Feasibility

The problem of finding a vector with the fewest nonzero elements that satisfies an underdetermined system of linear equations is an NP-complete problem that is typically solved numerically via convex heuristics or nicely-behaved nonconvex relaxations. In this work we consider elementary methods based on projections for solving a sparse feasibility problem without employing convex heuristics. It has been shown recently that, locally, the fundamental method of alternating projections must converge linearly to a solution to the sparse feasibility problem with an affine constraint. In this paper we apply different analytical tools that allow us to show global linear convergence of alternating projections under familiar constraint qualifications. These analytical tools can also be applied to other algorithms. This is demonstrated with the prominent Douglas-Rachford algorithm where we establish local linear convergence of this method applied to the sparse affine feasibility problem.
Deriving concept hierarchies from text

Abstract : This paper presents a means of automatically deriving a hierarchical organization of concepts from a set of documents without use of training data or standard clustering techniques. Instead, salient words and phrases extracted from the documents are organized hierarchically using a type of co-occurrence known as subsumption. The resulting structure is displayed as a series of hierarchical menus. When generated from a set of retrieved documents, a user browsing the menus is provided with a detailed overview of their content in a manner distinct from existing overview and summarization techniques. The methods used to build the structure are simple, but appear to be effective: a smallscale user study reveals that the generated hierarchy possesses properties expected of such a structure in that general terms are placed at the top levels leading to related and more specific terms below. The formation and presentation of the hierarchy is described along with the user study and some other informal evaluations. The organization of a set of documents into a concept hierarchy derived automatically from the set itself is undoubtedly one goal of information retrieval. Were this goal to be achieved, the documents would be organized into a form somewhat like existing manually constructed subject hierarchies, such as the Library of Congress categories, or the Dewey Decimal system. The only difference being that the categories would be customized to the set of documents itself. For example, from a collection of media related articles, the category "Entertainment" might appear near the top level; below it, (amongst others) one might find the category "Movies", a type of entertainment; and below that, there could be the category "Actors & Actresses", an aspect of movies. As can be seen, the arrangement of the categories provides an overview of the topic structure of those articles.
LiV3O8/Polytriphenylamine Composites with Enhanced Electrochemical Performances as Cathode Materials for Rechargeable Lithium Batteries

LiV3O8/polytriphenylamine composites are synthesized by a chemical oxidative polymerization process and applied as cathode materials for rechargeable lithium batteries (RLB). The structure, morphology, and electrochemical performances of the composites are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, galvanostatic discharge/charge tests, and electrochemical impedance spectroscopy. It was found that the polytriphenylamine particles were composited with LiV3O8 nanorods which acted as a protective barrier against the side reaction of LiV3O8, as well as a conductive network to reduce the reaction resistance among the LiV3O8 particles. Among the LiV3O8/polytriphenylamine composites, the 17 wt % LVO/PTPAn composite showed the largest d100 spacing. The electrochemical results showed that the 17 wt % LVO/PTPAn composite maintained a discharge capacity of 271 mAh·g−1 at a current density of 60 mA·g−1, as well as maintaining 236 mAh·g−1 at 240 mA·g−1 after 50 cycles, while the bare LiV3O8 sample retained only 169 and 148 mAh·g−1, respectively. Electrochemical impedance spectra (EIS) results implied that the 17 wt % LVO/PTPAn composite demonstrated a decreased charge transfer resistance and increased Li+ ion diffusion ability, therefore manifesting better rate capability and cycling performance compared to the bare LiV3O8 sample.
Exploring the Reasons for Using Electric Books and Technologic Pedagogical and Content Knowledge of Taiwanese Elementary Mathematics and Science Teachers.

This study highlights trends and features of E-books and their versatility of this tool in elementary educational settings. There has been little quantitative research employed to examine teachers’ reasons for using or not using E-books. The purpose of this study was to examine elementary school mathematics and science teachers’ reasons for using or not using E-books and to assess how the use of E-books relates to TPACK among Taiwanese teachers. The survey was developed based on an overview of discussions from prior research related to the benefits and drawbacks of using E-books. The results show the percentages for four reasons for using E-books were high, and low for four reasons for not using E-books. The teachers’ perceptions of E-books’ usefulness and ability to increase motivation and interaction were significantly different according to gender and the perceptions of E-books’ ability to increase interaction were significantly different according to teaching experience. Elementary science teachers demonstrated significantly higher TPACK than elementary mathematics teachers. There was no significant difference found in TPACK according to gender, except for in teachers’ technological knowledge. Teachers who had more years of teaching experience demonstrated significantly higher TPACK than the teachers who had fewer years of teaching experience. The results of this study can provide researchers, policy makers, and school administrators with a better understanding of elementary school teachers’ perspectives.
