Contractor key competitiveness indicators: A China study

A proper method to assess contractor competitiveness is important both for assisting clients in the selection of proper contractors and for assisting contractors in the development of more competitive bidding strategies. Previous studies have identified various indicators for assessing contractor competitiveness, and several assessment methods have been introduced. Nevertheless, these studies are limited because they are unable to tell which indicators are more important in different market environments. This paper identifies the key competitiveness indicators �KCIs� for assessing contractor competitiveness in the Chinese construction market. An index value is used to indicate the relative significance of various competitiveness indicators based on which KCIs are identified. The data applied in this study are from a survey of the construction industry in mainland China. The research findings provide valuable information for both existing businesses and the construction professionals who plan to compete for construction works in the Chinese market. The study provides useful references for further studies that compare the KCIs used in the Chinese construction industry and those used in other construction industries.

Reforming the House of Lords: difficult but not impossible

Despite apparent cross-party and public support, Nick Clegg’s plan to reform the House of Lords is dead. This article asks what explains its demise and analyses whether comprehensive Lords reform is ever likely to get off the ground in the future.

Radical Conservatism

In 1938, Yugoslav sculptor Oscar Nemon arrived in Britain, having fled the Nazi invasion of Brussels, where he was living with Magritte. He was part of the European avant-garde that came to the UK as a refugee. Shortly thereafter, Nemon proposed a bold architectural plan to construct a temple of universal ethics in London and was in correspondence over this with central figures in Britain. After the war, he became know for his portrayal of figures like Churchil, culminating in a bust of Margaret Thatcher that is currently at the Tory HQ. Shown at Castlefield Gallery in 2013-2014, Radical Conservatism was an exhibition that explored the space between these two moments and asked whether these two terms are really antithetical. In the British context in particular, where the European avant-garde never really took hold, a kind of reactionary modernism has always defined a culture wary of revolution. But today more than ever, with the left increasingly holding on to the past of the welfare state as an ideal, and the right quietly revolutionising our world through neoliberal reforms, the paradigms of radicalism and conservatism need to be redefined. Can conservatism be seen as a radical position in itself? If art is defined by a movement towards the new - could 'holding on to the past' stubbornly be seen as a critical position, now that neo-liberalism has forced a far more radical shift in politics than the left has managed in a long time? Curated by Pil and Galia Kollectiv, featuring work by Chris Evans, IRWIN, Pil and Galia Kollectiv, Joseph Lewis, Patrick Moran, Oscar Nemon and Public Movement and a symposium with contributions from Professor Alun Rowlands and Robert Garnett.

Enriching enterprise resource planning systems for strategic advantage: a semiotic motivated approach

Enterprise Resource Planning is often endorsed as a means to facilitate strategic advantage for businesses. The scarcity of resources is the method by which some businesses maintain their position. However, the ubiquitous trend towards the adoption of Enterprise Resourcing Planning systems coupled with market saturation makes the promise of advantage less compelling. Reported in this paper is a proposed solution based upon semiotic theory that takes a typical Enterprise Resource Planning deployment scenario and shapes it according to the needs of people in post-implementation contexts to leverage strategic advantage in different ways.

Towards a model-based integration of co-registered electroencephalography/functional magnetic resonance imaging data with realistic neural population meshes

Brain activity can be measured with several non-invasive neuroimaging modalities, but each modality has inherent limitations with respect to resolution, contrast and interpretability. It is hoped that multimodal integration will address these limitations by using the complementary features of already available data. However, purely statistical integration can prove problematic owing to the disparate signal sources. As an alternative, we propose here an advanced neural population model implemented on an anatomically sound cortical mesh with freely adjustable connectivity, which features proper signal expression through a realistic head model for the electroencephalogram (EEG), as well as a haemodynamic model for functional magnetic resonance imaging based on blood oxygen level dependent contrast (fMRI BOLD). It hence allows simultaneous and realistic predictions of EEG and fMRI BOLD from the same underlying model of neural activity. As proof of principle, we investigate here the influence on simulated brain activity of strengthening visual connectivity. In the future we plan to fit multimodal data with this neural population model. This promises novel, model-based insights into the brain's activity in sleep, rest and task conditions.

Unpicking antecedents of CRM adoption: a two-stage model

Most CRM work focuses on consumer applications. This paper addresses the operational adoption issues facing the organisation deploying CRM practices. There are a plethora of challenges facing organisations when adopting CRM. Previous research is limited to either examining the CRM adoption process at an individual/employees level or an organisational level. Hence, in this paper the myriad of organisational, marketing and technical antecedents that seem to impinge upon employee perceptions and organisational implementation of CRM are structured in a two-stage model. Using a stratified sample of ten organisations across four sectors, seven hypotheses are tested on data collected from 301 practitioners. A two-stage model is analysed using structural equation modelling. Findings reveal that CRM implementation relates to employee perceptions of CRM. This paper deepens our understanding of organisational practices to adopt CRM, so as an organisation properly profits from the expected benefits of CRM.

THE ROLE OF THE SUPERIOR COLLICULUS IN PREDATORY HUNTING

Combining the results of behavioral, neuronal immediate early gene activation, lesion and neuroanatomical experiments, we have presently investigated the role of the superior colliculus (SC) in predatory hunting. First, we have shown that insect hunting is associated with a characteristic large increase in Fos expression in the lateral part of the intermediate gray layer of the SC (Wig). Next, we have shown that animals with bilateral NMDA lesions of the lateral parts of the SC presented a significant delay in starting to chase the prey and longer periods engaged in other activities than predatory hunting. They also showed a clear deficit to orient themselves toward the moving prey and lost the stereotyped sequence of actions seen for capturing, holding and killing the prey. Our Phaseolus vulgaris-leucoagglutinin analysis revealed that the lateral SCig, besides providing the well-documented descending crossed pathway to premotor sites in brainstem and spinal cord, projects to a number of midbrain and diencephalic sites likely to influence key functions in the context of the predatory behavior, such as general levels of arousal, motivational level to hunt or forage, behavioral planning, appropriate selection of the basal ganglia motor plan to hunt, and motor output of the primary motor cortex. In contrast to the lateral SC lesions, medial SC lesions produced a small deficit in predatory hunting, and compared to what we have seen for the lateral SCig, the medial SCig has a very limited set of projections to thalamic sites related to the control of motor planning or motor output, and provides conspicuous inputs to brainstem sites involved in organizing a wide range of anti-predatory defensive responses. Overall, the present results served to clarify how the different functional domains in the SC may mediate the decision to pursue and hunt a prey or escape from a predator. (C) 2010 IBRO.

The Schenberg spherical gravitational wave detector: the first commissioning runs

Here we present a status report of the first spherical antenna project equipped with a set of parametric transducers for gravitational detection. The Mario Schenberg, as it is called, started its commissioning phase at the Physics Institute of the University of Sao Paulo, in September 2006, under the full support of FAPESP. We have been testing the three preliminary parametric transducer systems in order to prepare the detector for the next cryogenic run, when it will be calibrated. We are also developing sapphire oscillators that will replace the current ones thereby providing better performance. We also plan to install eight transducers in the near future, six of which are of the two-mode type and arranged according to the truncated icosahedron configuration. The other two, which will be placed close to the sphere equator, will be mechanically non-resonant. In doing so, we want to verify that if the Schenberg antenna can become a wideband gravitational wave detector through the use of an ultra-high sensitivity non-resonant transducer constructed using the recent achievements of nanotechnology.

Asymptotic Skewness in Exponential Family Nonlinear Models

In this article, we give an asymptotic formula of order n(-1/2), where n is the sample size, for the skewness of the distributions of the maximum likelihood estimates of the parameters in exponencial family nonlinear models. We generalize the result by Cordeiro and Cordeiro ( 2001). The formula is given in matrix notation and is very suitable for computer implementation and to obtain closed form expressions for a great variety of models. Some special cases and two applications are discussed.

Visualization of spirography-based objective measures in Parkinson's disease

Objective: To investigate whether advanced visualizations of spirography-based objective measures are useful in differentiating drug-related motor dysfunctions between Off and dyskinesia in Parkinson’s disease (PD). Background: During the course of a 3 year longitudinal clinical study, in total 65 patients (43 males and 22 females with mean age of 65) with advanced PD and 10 healthy elderly (HE) subjects (5 males and 5 females with mean age of 61) were assessed. Both patients and HE subjects performed repeated and time-stamped assessments of their objective health indicators using a test battery implemented on a telemetry touch screen handheld computer, in their home environment settings. Among other tasks, the subjects were asked to trace a pre-drawn Archimedes spiral using the dominant hand and repeat the test three times per test occasion. Methods: A web-based framework was developed to enable a visual exploration of relevant spirography-based kinematic features by clinicians so they can in turn evaluate the motor states of the patients i.e. Off and dyskinesia. The system uses different visualization techniques such as time series plots, animation, and interaction and organizes them into different views to aid clinicians in measuring spatial and time-dependent irregularities that could be associated with the motor states. Along with the animation view, the system displays two time series plots for representing drawing speed (blue line) and displacement from ideal trajectory (orange line). The views are coordinated and linked i.e. user interactions in one of the views will be reflected in other views. For instance, when the user points in one of the pixels in the spiral view, the circle size of the underlying pixel increases and a vertical line appears in the time series views to depict the corresponding position. In addition, in order to enable clinicians to observe erratic movements more clearly and thus improve the detection of irregularities, the system displays a color-map which gives an idea of the longevity of the spirography task. Figure 2 shows single randomly selected spirals drawn by a: A) patient who experienced dyskinesias, B) HE subject, and C) patient in Off state. Results: According to a domain expert (DN), the spirals drawn in the Off and dyskinesia motor states are characterized by different spatial and time features. For instance, the spiral shown in Fig. 2A was drawn by a patient who showed symptoms of dyskinesia; the drawing speed was relatively high (cf. blue-colored time series plot and the short timestamp scale in the x axis) and the spatial displacement was high (cf. orange-colored time series plot) associated with smooth deviations as a result of uncontrollable movements. The patient also exhibited low amount of hesitation which could be reflected both in the animation of the spiral as well as time series plots. In contrast, the patient who was in the Off state exhibited different kinematic features, as shown in Fig. 2C. In the case of spirals drawn by a HE subject, there was a great precision during the drawing process as well as unchanging levels of time-dependent features over the test trial, as seen in Fig. 2B. Conclusions: Visualizing spirography-based objective measures enables identification of trends and patterns of drug-related motor dysfunctions at the patient’s individual level. Dynamic access of visualized motor tests may be useful during the evaluation of drug-related complications such as under- and over-medications, providing decision support to clinicians during evaluation of treatment effects as well as improve the quality of life of patients and their caregivers. In future, we plan to evaluate the proposed approach by assessing within- and between-clinician variability in ratings in order to determine its actual usefulness and then use these ratings as target outcomes in supervised machine learning, similarly as it was previously done in the study performed by Memedi et al. (2013).

The differential roles of D-Pax2 variants in regulating Drosophila eye and bristle development

The ability to appropriately interact with the environment is crucial to an organism’s survival. The establishment of functional sensory systems, such as the bristles and eyes in Drosophila, is a critical event during the development of the organism. The transcription factor D Pax2 is involved in the differentiation of the shaft and glial cells in the developing bristle (Kavaler et al., Dev, 126:2261-2272, 1999) and of the cone and primary pigment cells in the developing eye (Fu and Noll, Genes Dev, 11:389-405, 1997). How D-Pax2 contributes to distinct differentiative pathways in different cell types is not known. Recent work by Anna Czechowski and Katherine Harmon (personal communication) identified a mutation in the D-Pax2 gene that introduced a stop codon at the end of exon 9, effectively truncating the protein. This mutation affects bristle, but not eye, development. We thus suspected regions after exon 9 are required for D-Pax2 function only in the bristles and may also be associated with alternative splicing of the D Pax2 transcript. We plan to assess the role of the carboxy terminal region of the protein by establishing transgenic lines bearing rescue constructs of D-Pax2 with either the complete coding sequence or with deletions of specific exons. To date, we have generated the first rescue construct bearing the complete coding region of the gene driven by a 3 KB upstream regulatory region of D-Pax2 and are currently generating transgenic fly lines with this construct.

Mercado de capitais e financiamento privado para o desenvolvimento

This research argues that Brazil should create conditions for long run financing of development. The end of the inflationary process is just a first step. A second step is the development of an institutional framework to offer good alternatives to investors that have long run targets, such as pension funds etc. Particularly, in the Brazilian market predominates the trade of preferred shares instead of common shares that give more prerrogatives for investors that plan to hold these shares on long term basis. This attitude turns the market more volatile and in this way corporations lose the chance of financing their projects with large amounts of capital and have to rely instead on more debt which weakens their financial strenght.

Um desafio para a regulação do mercado de assistência à saúde no Brasil: a escolha do consumidor de planos de saúde

The objective of this dissertation is to discover and to analyze the way how the consumer uses his/her perception to decide contracting a health plan, to supply elements that can serve to subsidize the State, the market and the consumers, in relation to the knowledge on the process of choice of the consumer and the decisions of purchase and contracting services of private health. The estimated one is to evidence that the brand of health plan is an important variable and decisive to the consumer contracting the service of a company that operates in these sector, because mean for the consumer security about the product, through the symbolism that the same one represents, despite the consumer not knowing to the certainty what is contracting in quality and amount. The theoretical construction is carried through using literature of anthropology of the consumption, theory of modernity, theory of the regulation, economic utilitarism, and marketing. Moreover, referential specific theoretician on the regulation of the market of health plans in Brazil. The health plan market in Brazil is anti-symmetrical and the consumer doesn¿t have knowledge technician who makes possible it to form judgment and to carry through rationality choices. Than the consumer uses to his/her decision symbolic elements that are available to his/her and supply to his/her the security that is look likes in the consumption of this kind of good. These symbolic elements related the confidence and security and are into the strong brands of the companies and are transmitted to the consumer through the mass media. In this dissertation are used as sources of data some information of the regulatory agency of the sector ¿ ANS -, a research of public opinion with health plans users and the results of the application of proper questionnaires for this research.

Universidades Corporativas: Proposiçâo de um Modelo Conceitual

The aim of the present study is to develop a Corporate University Model, that could be adapted to great national companies, contributing pragmatically to recent developments in corporate education. For this reason, a larger understanding of the phenomenon that represents the appearance of those entities in the dynamics of the managerial education process, was sought, through the study of its main characteristics, a distinction between them, academic universities and also the traditional process of corporate education, targeting a set of specific requirements for successful implementation. The study was developed with a qualitative focus, aiming to analyze the theories and models now existent, signaling to educational professionals and company executives important aspects in its execution. This led to an overview of the themes that generate new alternatives for those who need to make decisions related to the subject. A reading of the publishments on higher education in Brazil and the Brazilian university model, on managerial education and what could be found on corporate universities, was carried out. Soon after, researches were made in companies that had similar implemented models or those in the process of implementation, seeking to know its main differences, likenesses and peculiarities. Meticulous study and the attentive analysis of the whole research material collected led to the proposition of the model, which was implanted in January of 2001, in Caixa Econômica Federal.
