Design: the quintessential business transaction

The fundamental structures that underpin business activities must evolve and change in order to equip companies to thrive in a market whose characteristics are increasing competition and instability. The incremental advances in applied computing technology and business methodologies which focus on improving one aspect of company operations ignore the need for an underlying structure and model through which to engage any and all functions in a consistent and integrated fashion. Indeed, many exacerbate the problem through closed architectures, isolationist views of entity data storage and rigid methodologies imposed on the company that employs them. The Product Model proposed fulfils that role. It is a model of the processes and entities that a company uses to conduct its business, at all levels and across all departments. Two other concepts are exposed: product model data and the design history record. Product model data are the values of instances of product model entities and relations, created to represent a particular design, artefact or object. The design history record captures the data and functions used in a transaction and the order and context in which they are used. To exercise these concepts, a software suite was written, the Glasgow Utility for Integrated Design, Guide. It supports the definition of a proud model and its subsequent use in the creation of product model data. Each interaction with the system is recorded, thus capturing the design history record, which can subsequently be processes to various advantageous ends. The major such uses are for re-use of part information in other designs and the extraction of design best practice with which to augment the company's design methodology. It is a comprehensive record, since all business processes are supported by, and can be transacted through Guide. Guide has been used to validate the adequacy of the product model and has established many benefits through its use. Applications in many spheres are possible; engineering has been the primary focus for exemplars and case studies. The development was carried out under the scrutiny of constant validation and testing in live situations with several industrial partners. Guide is built on industry standard tools and uses relational database technology to store frame-based representations of entities, methods and relationships. The design of project plans is carried out on the same platform used to support the project itself; the design data are not dissociated from the project controlling mechanism. Resources, including staff, are engaged according to requirements and audit mechanisms allow for constant re-evaluation of the project development. Control and communication mechanisms support applications in an extended enterprise environment and the distribution of resources that this entails

Polymorphisms of an Innate Immune Gene, Toll-Like Receptor 4, and Aggressive Prostate Cancer Risk: A Systematic Review and Meta-Analysis

Background: Toll-like receptor 4 (TLR4) is one of the best known TLR members expressed on the surface of several leukocytes and tissue cells and has a key function in detecting pathogen and danger-associated molecular patterns. The role of TLR4 in the pathophysiology of several age-related diseases is also well recognized, such as prostate cancer (PCa). TLR4 polymorphisms have been related to PCa risk, but the relationship between TLR4 genotypes and aggressive PCa risk has not been evaluated by any systematic reviews. Methods: We performed a systematic review and meta-analysis of candidate-gene and genome-wide association studies analyzing this relationship and included only white population. Considering appropriate criteria, only nine studies were analyzed in the meta-analysis, including 3,937 aggressive PCa and 7,382 controls. Results: Using random effects model, no significant association was found in the ten TLR4 SNPs reported by at least four included studies under any inheritance model (rs2737191, rs1927914, rs10759932, rs1927911, rs11536879, rs2149356, rs4986790, rs11536889, rs7873784, and rs1554973). Pooled estimates from another ten TLR4 SNPs reported by three studies also showed no significant association (rs10759930, rs10116253, rs11536869, rs5030717, rs4986791, rs11536897, rs1927906, rs913930, rs1927905, and rs7045953). Meta-regression revealed that study type was not a significant source of between-study heterogeneity. Conclusions: TLR4 polymorphisms were not significantly associated with the risk of aggressive PCa

The Multicultural Classroom as a Comparative Law Site: A United Kingdom Perspective

This chapter studies the impact of the recent multicultural approach to comparative legal studies on comparative law teaching, with a focus on British debates and literature. I will argue that the multicultural turn of (comparative) legal teaching, reflected for example in a greater diversity of teaching techniques, a greater emphasis on minority issues and law &… disciplines, responds to a multiplicity of motivations. Pedagogically, it is a response to the increasingly diverse backgrounds of students and their differing intellectual starting-points. Pragmatically, it is a means to boost students’ employability and intellectual versality in a job market that now values “cultural awareness skills”. Finally, conceptually, it is a tool designed to unravel the pluralistic nature of law. From these diverse drivers to the multicultural turn in (comparative) legal teaching, it is possible to identify similarities with other recent trends of globalisation and internationalisation of legal education. However, this article will submit that differences remain. Having analysed these differences, I will go on to argue and reveal that in them lie the core features of a multicultural approach to legal teaching and its intrinsic connections to comparative law, as the multicultural classroom itself becomes a comparative law site

First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signalto- noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars over a fraction of a hertz and several spin-down values. In this paper we describe a narrow-band search of 11 pulsars using data from Advanced LIGO’s first observing run. Although we have found several initial outliers, further studies show no significant evidence for the presence of a gravitational wave signal. Finally, we have placed upper limits on the signal strain amplitude lower than the spin-down limit for 5 of the 11 targets over the bands searched; in the case of J1813-1749 the spin-down limit has been beaten for the first time. For an additional 3 targets, the median upper limit across the search bands is below the spin-down limit. This is the most sensitive narrow-band search for continuous gravitational waves carried out so far

Fine-mapping identifies multiple prostate cancer risk loci at 5p15, one of which associates with TERT expression

Associations between single nucleotide polymorphisms (SNPs) at 5p15 and multiple cancer types have been reported. We have previously shown evidence for a strong association between prostate cancer (PrCa) risk and rs2242652 at 5p15, intronic in the telomerase reverse transcriptase (TERT) gene that encodes TERT. To comprehensively evaluate the association between genetic variation across this region and PrCa, we performed a fine-mapping analysis by genotyping 134 SNPs using a custom Illumina iSelect array or Sequenom MassArray iPlex, followed by imputation of 1094 SNPs in 22 301 PrCa cases and 22 320 controls in The PRACTICAL consortium. Multiple stepwise logistic regression analysis identified four signals in the promoter or intronic regions of TERT that independently associated with PrCa risk. Gene expression analysis of normal prostate tissue showed evidence that SNPs within one of these regions also associated with TERT expression, providing a potential mechanism for predisposition to disease

Stable isotope food-web analysis and mercury biomagnification in polar bears ( Ursus maritimus )

Mercury (Hg) biomagnification occurs in many ecosystems, resulting in a greater potential for toxicological effects in higher-level trophic feeders. However, Hg transport pathways through different food-web channels are not well known, particularly in high-latitude systems affected by the atmospheric Hg deposition associated with snow and ice. Here, we report on stable carbon and nitrogen isotope ratios, and Hg concentrations, determined for 26, late 19th and early 20th century, polar bear ( Ursus maritimus ) hair specimens, collected from catalogued museum collections. These data elucidate relationships between the high-latitude marine food-web structure and Hg concentrations in polar bears. The carbon isotope compositions of polar bear hairs suggest that polar bears derive nutrition from coupled food-web channels, based in pelagic and sympagic primary producers, whereas the nitrogen isotope compositions indicate that polar bears occupy > fourth-level trophic positions. Our results show a positive correlation between polar bear hair Hg concentrations and δ 15 N. Interpretation of the stable isotope data in combination with Hg concentrations tentatively suggests that polar bears participating in predominantly pelagic food webs exhibit higher mercury concentrations than polar bears participating in predominantly sympagic food webs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73930/1/j.1751-8369.2009.00114.x.pd

Rapid Discovery and Structure-Activity Relationships of Pyrazolopyrimidines that Potently Suppress Breast Cancer Cell Growth via SRC Kinase Inhibition with Exceptional Selectivity over ABL Kinase

Novel pyrazolopyrimidines displaying high potency and selectivity toward SRC family kinases have been developed by combining ligand-based design and phenotypic screening in an iterative manner. Compounds were derived from the promiscuous kinase inhibitor PP1 to search for analogs that could potentially target a broad spectrum of kinases involved in cancer. Phenotypic screening against MCF7 mammary adenocarcinoma cells generated target-agnostic structure–activity relationships that biased subsequent designs toward breast cancer treatment rather than to a particular target. This strategy led to the discovery of two potent antiproliferative leads with phenotypically distinct anticancer mode of actions. Kinase profiling and further optimization resulted in eCF506, the first small molecule with subnanomolar IC₅₀ for SRC that requires 3 orders of magnitude greater concentration to inhibit ABL. eCF506 exhibits excellent water solubility, an optimal DMPK profile and oral bioavailability, halts SRC-associated neuromast migration in zebrafish embryos without inducing life-threatening heart defects, and inhibits SRC phosphorylation in tumor xenografts in mice

Synaptopathies: Dysfunction of Synaptic Function Confirmed rare copy number variants implicate novel genes in schizophrenia

Abstract Understanding how cognitive processes including learning, memory, decision making and ideation are encoded by the genome is a key question in biology. Identification of sets of genes underlying human mental disorders is a path towards this objective. Schizophrenia is a common disease with cognitive symptoms, high heritability and complex genetics. We have identified genes involved with schizophrenia by measuring differences in DNA copy number across the entire genome in 91 schizophrenia cases and 92 controls in the Scottish population. Our data reproduce rare and common variants observed in public domain data from >3000 schizophrenia cases, confirming known disease loci as well as identifying novel loci. We found copy number variants in PDE10A (phosphodiesterase 10A), CYFIP1 [cytoplasmic FMR1 (Fragile X mental retardation 1)-interacting protein 1], K + channel genes KCNE1 and KCNE2, the Down's syndrome critical region 1 gene RCAN1 (regulator of calcineurin 1), cell-recognition protein CHL1 (cell adhesion molecule with homology with L1CAM), the transcription factor SP4 (specificity protein 4) and histone deacetylase HDAC9, among others (see http://www.genes2cognition.org/SCZ-CNV). Integrating the function of these many genes into a coherent model of schizophrenia and cognition is a major unanswered challenge
