Statistical Ring Opening Metathesis Copolymerization of Norbornene and Cyclopentene by Grubbs’ 1st-Generation Catalyst

Statistical copolymers of norbornene (NBE) with cyclopentene (CP) were prepared by ring-opening metathesis polymerization, employing the 1st-generation Grubbs’ catalyst, in the presence or absence of triphenylphosphine, PPh3. The reactivity ratios were estimated using the Finemann-Ross, inverted Finemann-Ross, and Kelen-Tüdos graphical methods, along with the computer program COPOINT, which evaluates the parameters of binary copolymerizations from comonomer/copolymer composition data by integrating a given copolymerization equation in its differential form. Structural parameters of the copolymers were obtained by calculating the dyad sequence fractions and the mean sequence length, which were derived using the monomer reactivity ratios. The kinetics of thermal decomposition of the copolymers along with the respective homopolymers was studied by thermogravimetric analysis within the framework of the Ozawa-Flynn-Wall and Kissinger methodologies. Finally, the effect of triphenylphosphine on the kinetics of copolymerization, the reactivity ratios, and the kinetics of thermal decomposition were examined.
The impact of the economic crisis on Spanish university libraries

espanolEl presente trabajo tiene como objetivo examinar el impacto de la crisis financiera en las bibliotecas de las universidades publicas espanolas. Para alcanzar este proposito se han analizado los datos de personal, los datos economicos, y los referidos a los servicios prestados por las 47 bibliotecas universitarias publicas durante el periodo 2008 a 2014. El analisis de los datos nos lleva a aseverar, a nivel global, las siguientes consideraciones: estas bibliotecas han experimentado una reduccion en los efectivos de personal y en los gastos de adquisiciones de recursos de informacion, mientras que el volumen del prestamo domiciliario ha seguido una evolucion similar al del numero de estudiantes matriculados. Tanto el prestamo interbibliotecario como el numero de dias que permanecieron abiertas las bibliotecas durante estos anos tambien han disminuido. El gasto en recursos electronicos, realizado por las bibliotecas y los consorcios bibliotecarios, se ha incrementado en el periodo estudiado a expensas del gasto en monografias y en revistas en soporte papel. En este nuevo entorno economico, consideramos que los gestores bibliotecarios deben disenar acciones orientadas al establecimiento de estrategias que aseguren una oferta de servicios eficientes y de calidad para los usuarios. EnglishThe scope of this study is to examine the impact of the financial crisis on the libraries of Spanish public universities. For this purpose, data from staff, finances, and services provided by the 47 public university libraries during 2008-2014 have been analyzed. Overall, the analysis of the data leads us to assert the following observations: these libraries have experienced a reduction in staff and expenditures for the purchase of information resources, whereas the volume of library lending has matched the evolution of student enrollment. Both interlibrary lending and the number of days that libraries were open during this period have decreased. Expenditures on electronic resources made by libraries and library consortia have increased in the period under study to the detriment of expenditures on monographs and printed journals. In this new economic environment, we consider that library managers should design actions for establishing strategies to ensure efficient and high-quality services to users.
Organizational climate and investigation performance in the Norwegian police: A qualitative study

The present study aimed to identify organizational climate dimensions that are salient for police investigation performance and to explicate the mechanisms of the relationship between organizational climate and investigation performance. We conducted 38 semistructured interviews with participants at three job levels of police investigative work (chiefs of police, n = 11, senior investigating officers, n = 14, detectives, n = 13) in 11 Norwegian police districts. We analyzed the interview data by using a model of organizational climate based on the competing values framework (Quinn & Rohrbaugh, 1983). Two types of climate, human relations climate and rational goal climate, were perceived to enhance investigation performance. The findings indicate that a human relations climate enhances investigation performance by developing collective human capital and by supporting internal and external cooperation and coordination of resources. Moreover, the findings suggest that a rational goal climate increases investigation performance by encouraging planning, goal setting, and task focus.
Health service accreditation reinforces a mindset of high-performance human resource management: lessons from an Australian study.

OBJECTIVE To investigate whether an accreditation program facilitates healthcare organizations (HCOs) to evolve and maintain high-performance human resource management (HRM) systems. DESIGN Cross-sectional multimethod study. SETTING AND PARTICIPANTS Healthcare organizations participating in the Australian Council on Healthcare Standards Evaluation and Quality Improvement Program (EQuIP 4) between 2007 and 2011. MAIN OUTCOME MEASURES Ratings across the EQuIP 4 HRM criteria, a clinical performance measure, surveyor reports (HRM information) and interview data (opinions and experiences regarding HRM and accreditation). RESULTS Healthcare organizations identified as high performing on accreditation HRM criteria seek excellence primarily because of internal motivations linked to best practice. Participation in an accreditation program is a secondary and less significant influence. Notwithstanding, the accreditation program provides the HCO opportunity for internal and external review and assessment of their performance; the accreditation activities are reflective learning and feedback events. CONCLUSIONS This study reveals that HCOs that pursue highly performing HRM systems use participation in an accreditation program as an opportunity. Their organizational mindset is to use the program as a tool by which to reflect and obtain feedback on their performance so to maintain or improve their management of staff and delivery of care.
The revised two-factor Study Process Questionnaire: R-SPQ-2F.

AIM To produce a revised two-factor version of the Study Process Questionnaire (R-SPQ-2F) suitable for use by teachers in evaluating the learning approaches of their students. The revised instrument assesses deep and surface approaches only, using fewer items. METHOD A set of 43 items was drawn up for the initial tests. These were derived from: the original version of the SPQ, modified items from the SPQ, and new items. A process of testing and refinement eventuated in deep and surface motive and strategy scales each with 5 items, 10 items per approach score. The final version was tested using reliability procedures and confirmatory factor analysis. SAMPLE The sample for the testing and refinement process consisted of 229 students from the health sciences faculty of a university in Hong Kong. A fresh sample of 495 undergraduate students from a variety of departments of the same university was used for the test of the final version. RESULTS The final version of the questionnaire had acceptable Cronbach alpha values for scale reliability. Confirmatory factor analysis indicated a good fit to the intended two-factor structure. Both deep and surface approach scales had well identified motive and strategy subscales. CONCLUSION The revision process has resulted in a simple questionnaire which teachers can use to evaluate their own teaching and the learning approaches of their students.

In this review, applications in medicine that are revolutionizing the way surgeries are carried out, disrupting prosthesis and implant markets as well as dentistry will be presented. The relatively new field of bioprinting, that is printing with cells, will also be briefly discussed.
Predicting the revolving door phenomenon among patients with schizophrenic, affective disorders and non-organic psychoses.

OBJECTIVE The aim of the study was to identify the variables that predict the revolving door phenomenon in psychiatric hospital at the moment of a second admission. METHODS The sample consisted of 3,093 patients who have been followed during 5 to 24 years after their first hospital admission due to schizophrenia, and affective or psychotic disorders. Those who had had four or more admissions during the study period were considered as revolving door patients. Logistic regression analyses were used to assess the impact of gender, age, marital status, urban conditions, diagnosis, mean period of stay on the first admission, interval between the first and second admissions on the patterns of hospitalization. RESULTS The variables with the highest predictive power for readmission were the interval between first and second admissions, and the length of stay in the first admission. CONCLUSIONS These data may help public health planners in providing optimal care to a small group of patients with more effective utilization of the available services.
Correlations Decrease with Propagation of Spiking Activity in the Mouse Barrel Cortex

Propagation of suprathreshold spiking activity through neuronal populations is important for the function of the central nervous system. Neural correlations have an impact on cortical function particularly on the signaling of information and propagation of spiking activity. Therefore we measured the change in correlations as suprathreshold spiking activity propagated between recurrent neuronal networks of the mammalian cerebral cortex. Using optical methods we recorded spiking activity from large samples of neurons from two neural populations simultaneously. The results indicate that correlations decreased as spiking activity propagated from layer 4 to layer 2/3 in the rodent barrel cortex.
Modelling Emergence

Emergence is defined as a process which cannot be described by a fixed model, consisting of invariant distinctions. Hence emergence must be described by a metamodel, representing the transition of one model to another one by means of a distinction dynamics. The dynamics of distinctions is based on the processes of variation and selection, resulting in an invariant distinction, which constrains the variety of and thus defines a new system. A classification of emergence processes is proposed, based on the following criteria: amount of variety, internality/ externality of variation and selection, number of levels, and contingency of constraint. It is argued that traditional formal and computational models are incapable of representing the more general types of emergence, but that it is possible to generalize them on the basis of the dynamics of distinctions.
Family Matters: Justice Gender and Female Litigant Success in Family Law Cases in the Supreme Court of Canada

ABSTRACT As the first empirical study of family law cases at the Supreme Court of Canada, this study explores potential factors that lead to female litigant success in family law cases. This study seeks to further our understanding of areas of law that, in particular, impact women and families. Analyzing the universe of decisions in family law cases decided by the Supreme Court of Canada from 1982 to 2008, I find support for justice gender affecting female litigant success in family law cases. The results suggest that female justices tend to support female litigants more often than their male colleagues, and that certain legal factors are also determinants of Supreme Court decisions in family law cases. Female litigants enjoy high rates of success at the Supreme Court of Canada, with both justice-specific and case-specific factors as driving forces in decision-making.
SimPack: A Generic Java Library for Similarity Measures in Ontologies

Good similarity measures are central for techniques such as retrieval, matchmaking, clustering, data-mining, ontology translations, automatic database schema matching, and simple object comparisons. Measures for the use with complex (or aggregated) objects in ontologies are, however, rare, even though they are central for semantic web applications. This paper ﬁrst introduces SimPack, a library of similarity measures for the use in ontologies (of complex objects). The measures of the library are then experimentally compared with a similarity “gold standard” established by surveying 94 human subjects in two ontologies. Results show that human and algorithm assessments vary (both between people and across ontologies), but can be grouped into cohesive clusters, each of which is well modeled by one of the measures in the library. Furthermore, we show two increasingly accurate methods to predict the cluster membership of the subjects providing the foundation for the construction of personalized similarity measures.
THE MAGNETIC FIELD TOWARD THE YOUNG PLANETARY NEBULA K 3-35

K 3-35 is a planetary nebula (PN) where H2O maser emission has been detected, suggesting that it departed from the proto-PNe phase only some decades ago. Interferometric VLA observations of the OH 18 cm transitions in K 3-35 are presented. OH maser emission is detected in all four ground state lines (1612, 1665, 1667, and 1720 MHz). All the masers appear blueshifted with respect to the systemic velocity of the nebula and have different spatial and kinematic distributions. The OH 1665 and 1720 MHz masers appear spatially coincident with the core of the nebula, while the OH 1612 and 1667 MHz ones exhibit a more extended distribution. We suggest that the 1665 and 1720 masers arise from a region close to the central star, possibly in a torus, while the 1612 and 1667 lines originate mainly from the extended northern lobe of the outflow. It is worth noting that the location and velocity of the OH 1720 MHz maser emission are very similar to those of the H2O masers (coinciding within 0.″1 and ∼ 2 km s−1, respectively). We suggest that the pumping mechanism in the H2O masers could be produced by the same shock that is exciting the OH 1720 MHz transition. A high degree of circular polarization (> 50%) was found to be present in some features of the 1612, 1665, and 1720 MHz emission. For the 1665 MHz transition at ∼ +18 km s−1 the emission with left and right circular polarizations (LCP and RCP) coincide spatially within a region of ∼ 0. ″03 in diameter. Assuming that these RCP and LCP 1665 features come from a Zeeman pair, we estimate a magnetic field of ∼ 0.9 mG within 150 AU from the 1.3 cm continuum peak. This value is in agreement with a solar-type magnetic field associated with evolved stars.
Requirements traceability state-of-the-art: A systematic review and industry case study

Requirements traceability enables software engineers to trace a requirement from its emergence to its fulﬁllment. In this paper we examine requirements traceability deﬁnitions, challenges, tools and techniques, by the use of a systematic review performing an exhaustive search through the years 1997–2007. We present a number of common deﬁnitions, challenges, available tools and techniques (presenting empirical evidence when found), while complementing the results and analysis with a static validation in industry through a series of interviews.
The park and the commons: vernacular spaces for everyday participation and cultural value

ABSTRACT Public parks were first established in the UK in the newly industrialised cities of Manchester and Salford, as nineteenth century cultural strategies for public health, regulation and education responding to moral anxieties about the changing conditions of everyday life. This article looks at public parks as vernacular spaces for everyday participation, drawing on empirical research, including ethnographic fieldwork, household interviews and focus groups, and community engagement conducted for the Manchester-Salford ecosystem case study of the ‘Understanding Everyday Participation – Articulating Cultural Value’ (UEP) project [Miles & Gibson, 2016. Everyday participation and cultural value. Cultural Trends, 5(3), 151–157]. It considers narratives of participation [Miles, 2016. Telling tales of participation: Exploring the interplay of time and territory in cultural boundary work using participation narratives. Cultural Trends, 5, 182–193], which reveal how parks are valued and recognised as community assets and spaces for both tolerance and distinction, where different communities can meet, become visible, and perform shared and distinct cultural identities [Low et al., 2005. Rethinking Urban Parks, Public Space and Cultural Diversity. Austin: University of Texas Press]. It draws on the conceptual device of ‘the commons’, defined as a dynamic and collective resource that stands in tension with commodified and privatised space [Gidwani & Baviskar, 2011. Urban Commons Review of Urban Affairs: Economic & Political Weekly, Volume XLVI No. 50 December 10, 2011. http://www.epw. in/journal/2011/50/review-urban-affairs-review-issues-specials/urban-commons.html]. , to explore how parks present opportunities for civic participation through contemporary processes of ‘commoning’ [Linebaugh, 2014. The Magna Carta Manifesto: Liberties and Commons for All. Berkeley: University of California Press]. I argue that parks are also subject to contemporary forms of enclosure through social exclusion and physical closure, which impact on the likely success of current policy imperatives for community asset transfer and alternative management models.
A systematic review of evidence for the appropriateness of neonatal screening programmes for inborn errors of metabolism.

BACKGROUND Developments in screening technology and increased understanding of the natural history and treatment of inborn errors of metabolism (IEMs) have produced pressure to extend neonatal screening programmes. This review aims to assess the evidence for the appropriateness of such programmes. METHODS A formal systematic literature review was conducted. Exclusion and inclusion criteria were used to select papers for critical appraisal by pairs of reviewers. Standard criteria were used to assess the appropriateness of neonatal screening for various IEMs. Site visits were conducted to assess new technologies for newborn screening. RESULTS A total of 1866 papers were identified and 407 systematically selected for full critical appraisal. Published evidence confirmed that universal newborn screening for phenylketonuria (PKU) meets all of the screening criteria and justifies the expense and infrastructure necessary for the collection and testing of neonatal blood spots. There was insufficient evidence in the literature to assess the cost-effectiveness of screening for any other IEMs. There was reasonable evidence to support inclusion in extended neonatal screening of four other IEMs: biotinidase deficiency, congenital adrenal hyperplasia (CAH), medium-chain acyl CoA dehydrogenase (MCAD) deficiency and glutaric aciduria type 1 (GA1). CONCLUSIONS Large-scale trials of screening for biotinidase, CAH, MCAD and GA1 should be conducted, with careful evaluation to establish their clinical effectiveness and cost-effectiveness in practice. Screening for the latter two disorders would be dependent upon the use of tandem mass spectrometry (tandem MS). The application of tandem MS to newborn screening requires further evaluation. The extension of neonatal screening programmes to other IEMs is not currently justified.
Is there really a gap between aggregate productivity and technology?

The important contribution by Basu and Fernald (2002) shows that, in practice, there is a statistically significant gap between aggregate productivity and technology that can be attributed to inefficient product and labour markets. This is important, as it implies that the Solow residual is an imperfect index for aggregate technology change. We take a related approach and find that when we control for capacity utilization, time varying markup and account for externalities between industries, by employing a superior system estimator, the gap between the aggregate productivity and technology is shown to narrow considerably.
Elementary results on the binary quadratic form a^2+ab+b^2

This paper examines with elementary proofs some interesting properties of numbers in the binary quadratic form $a^2+ab+b^2$, where $a$ and $b$ are non-negative integers. Key findings of this paper are (i) a prime number $p$ can be represented as $a^2+ab+b^2$ if and only if $p$ is of the form $6k+1$, with the only exception of 3, (ii) any positive integer can be represented as $a^2+ab+b^2$ if and only if its all prime factors that are not in the same form have even exponents in the standard factorization, and (iii) all the factors of an integer in the form $a^2+ab+b^2$, where $a$ and $b$ are positive and relatively prime to each other, are also of the same form. A general formula for the number of distinct representations of any positive integer in this form is conjectured. A comparison of the results with the properties of some other binary quadratic forms is given.
Assessment of ganciclovir toxicity to experimental intracranial gliomas following recombinant adenoviral-mediated transfer of the herpes simplex virus thymidine kinase gene by magnetic resonance imaging and proton magnetic resonance spectroscopy.

Magnetic resonance imaging and in vivo localized H magnetic resonance spectroscopy were used to evaluate a gene therapy approach for treating experimental brain tumors. This approach involved the use of an adenoviral vector to transfer the herpes simplex virus thymidine kinase (HSVtk) gene into intracerebral 9L gliosarcomas in rats followed by systemic administration of the antiherpetic agent ganciclovir. Magnetic resonance imaging quantitation of changes in intracranial 9L tumor doubling times revealed a significant variation in therapeutic response. Localized H magnetic resonance spectra of 9L tumors treated with Ad.RSVtk/ganciclovir revealed a dramatic increase in the resonance intensity at 0.9-1.3 ppm, corresponding to mobile lipids and/or lactate. Changes in intracranial tumor doubling times correlated with changes in H tumor magnetic resonance spectra, suggesting that specific changes in tumor metabolite levels may be predictive of the effectiveness of this gene therapy approach.
