The Asymmetric Fundamental Transformation

This paper examines how asymmetries between partners in the ability to appropriate the returns from collaboration affect governance choices and investment patterns. We consider multiple pairs of upstream and downstream firms, where firms must collaborate to improve product components. We show that when there are significant initial asymmetries in appropriability, components are easily redeployable and market size is sufficiently large for asymmetries to be exploited, then there exists a Pareto-inferior equilibrium where unstructured collaboration between independent firms breaks down. As a result, some pairs may be better off formalizing their relationship or integrating. All organizational forms (unstructured and structured partnerships, and integration) can co-exist in equilibrium, despite all pairs being identical ex ante and facing the same environment. The relationship is symbiotic: more hierarchical modes of governance exert a positive externality over less hierarchical modes, which allows the latter to be sustained.
Sustained lung inflation at birth for preterm infants at risk of respiratory distress syndrome: The proper pressure and duration.

BACKGROUND Variations exist among the administered pressure and duration of sustained lung inflation (SLI) in the delivery room (DR). We aimed to evaluate the appropriate pressure and duration needed for SLI in preterm infants with respiratory distress syndrome. METHODS We prospectively randomized 100 preterm (<32 weeks) infants to receive either conventional therapy of continuous positive airway pressure (CPAP) at 5 cm H2O, or four groups of CPAP plus a single maneuver of SLI at four regimens based on administered pressures and durations; P20D20 (Pressure of 20 cm H2O for a duration of 20 seconds), P20D10 (20 cm H2O for 10 seconds), P15D20 (15 cm H2O for 20 seconds), and P15D10 (15 cm H2O for 10 seconds) using a T-piece ventilator. The primary outcome was the need for endotracheal intubation (ETT) in the DR. Broncho-alveolar lavage (BAL) was obtained from intubated infants for interleukin-10 (IL-10) assessment. RESULTS SLI decreased the need for ETT in the DR (21% versus 55%, p < 0.01) compared to conventional therapy. ETT requirement was significantly lower in P20D10 (20%), P15D20 (20%), and P15D10 (20%) groups, but not P20D20 (25%) compared to the conventional group (55%, p < 0.05). Group P20D20 had significant higher BAL levels of IL-10 [713.8 (IQR 611-874) versus 535.4 (IQR 480-563) pg/ml, p < 0.05] compared to the conventional group, and to other SLI groups. Pneumothorax was not significantly different among studied groups. CONCLUSION SLI for a pressure and duration ≥20 cm H2O for 20 seconds is not superior to lower pressures for shorter duration and may be injurious to lungs.
Analysis of supplier selection methods through conceptual module and empirical study

Supplier selection is considered as the most important step in the course of supply chain management, which helps in reducing the costs, improve the quality and deliver the products on time, thereby sustaining the intense pressure in the present global competing environment. Many researchers have done their research on supplier selection and evaluation, the processes which determine the success of any supply chain and proposed new ideas and methods for the same. Around 225 articles from various journals have been reviewed. Based on the research in the previous literature, all the papers have been classified into three categories – conceptual approach, empirical study and analytical models. In this paper, we present a review of the past literature on supplier selection from 134 articles which include only the categories of conceptual approach and empirical study.
Course and Predictors of Suicidality Over the First Two Years of Treatment in First-Episode Schizophrenia Spectrum Psychosis

The objective of this study was to investigate the course of suicidal behavior over the first 2 years of comprehensive, integrated treatment in two groups of patients with DSM-IV first episode schizophrenia spectrum psychosis, where one group was recruited through an early detection program. We have previously shown that the rate of severe suicidal behavior was lower in the earlier detected group than in the other. First episode schizophrenia is a high risk period for suicidality, but we found low rates of completed suicides and suicide attempts in both groups after 2 years in treatment, with no between-groups differences. Severe suicidality (plans and attempts) was predicted by drug abuse, dissatisfaction with life and severe suicidality at start of treatment.
Vivid, full-color aluminum plasmonic pixels

Significance Full-color displays are typically fabricated using a combination of chromatic materials of various types, introduced into an addressable pixel-based electronic device. Here we show that brightly colored, highly vivid pixels, directly suitable for RGB displays, can be fabricated using periodic areas of Al nanorods in each pixel. Both nanorod length and spacing are critically important in achieving strong and spectrally distinct scattering signatures across the visible spectrum. This use of a low-cost, abundant metal for achieving full-spectrum coloration is compatible with complementary metal-oxide semiconductor manufacturing methods and directly applicable to current liquid crystal display technology. Aluminum is abundant, low in cost, compatible with complementary metal-oxide semiconductor manufacturing methods, and capable of supporting tunable plasmon resonance structures that span the entire visible spectrum. However, the use of Al for color displays has been limited by its intrinsically broad spectral features. Here we show that vivid, highly polarized, and broadly tunable color pixels can be produced from periodic patterns of oriented Al nanorods. Whereas the nanorod longitudinal plasmon resonance is largely responsible for pixel color, far-field diffractive coupling is used to narrow the plasmon linewidth, enabling monochromatic coloration and significantly enhancing the far-field scattering intensity of the individual nanorod elements. The bright coloration can be observed with p-polarized white light excitation, consistent with the use of this approach in display devices. The resulting color pixels are constructed with a simple design, are compatible with scalable fabrication methods, and provide contrast ratios exceeding 100:1.
On Continuous Distributions and Parameter Estimation in Probabilistic Logic Programs (Over continue verdelingen en het schatten van parameters in probabilistische logische programma's)

In the last decade remarkable progress has been made on combining statistical machine learning techniques, reasoning under uncertainty, and relational representations. The branch of Artificial Intelligence working on the synthesis of these three areas is known as statistical relational learning or probabilistic logic learning. ProbLog, one of the probabilistic frameworks developed, is an extension of the logic programming language Prolog with independent random variables that are defined by annotating logical facts with probabilities. The separation of the logical and probabilistic part of the model is based on the distribution semantics. Driven by the demand for models that are able to handle continuous values and can be automatically optimized on training data, this thesis introduces several algorithms and extensions to the ProbLog language. Continuous-valued data arise naturally in robotics, human activity recognition and bio-medical applications. Moreover, the models used are complex and the available data is often noisy and incomplete. Hence tuning a model towards the specifics of the environment can hardly be done manually. This poses two crucial challenges for probabilistic programming languages such as ProbLog: processing continuous values and being able to learn from training data. This thesis makes four main contributions to the field of probabilistic logic learning. Hybrid ProbLog is an extension for ProbLog with continuous facts that allows for exact inference. Distributional Programs combine elements of ProbLog, Hybrid ProbLog and CP-Logic into a very expressive language for dealing with continuous distributions. A sampling-based inference algorithm is used to answer conditional queries, while the deterministic information in the program guides the sampling process. LFE-ProbLog is able to learn the parameters of a ProbLog program from queries and proofs, while LFI-ProbLog is optimized to learn the parameters from partial interpretations. Together they cover the standard learning settings considered in PLL. All learning approaches have been evaluated in several relational real-world domains.
A normally closed MEMS micro reed switch with fill in liquid metal micro hinge structure

This study has successfully designed and implemented the first normally-closed (NC) micro reed switch (Fig.1). The NC-type reed switch consists three separate metal structures (hinge, movable pad/spring, and fixed-pad) and is assembled by an attractive magnetic force exerted by an out-of-plane magnetic field. Furthermore, as applying a strong enough in-plane magnetic field, the spring is deformed by repulsive magnetic force to separate the pads and turn-off the switch (Fig.2). Merits of this NC reed switch: (1) liquid-metal to ensure electrical connection at hinge, (2) UV-gel fixed hinge structure, and (3) magnetized repulsive actuating mechanism. Experiment demonstrates a typical fabricated NC reed switch with driving magnetic field of near 160Gauss (G), and releasing at near 150G. The contact resistance is between 0.2-5Ω. The contact resistance variation is near 13% under a 20G excitation.
Raman spectra of synthetic 'braggite', (Pd,Pt,Ni)S

Abstract Raman spectra of synthetic 'braggite' ((Pd,Pt,Ni)S) vary systematically with changes in Pt/Pd ratios, but this change is less pronounced than in 'cooperite' ((Pt,Pd,Ni)S). Compared to 'vysotskite' (ideally PdS), the incorporation of Pt leads to broadening of bands but the spectra of 'vysotskite' and 'braggite' are similar, and spectra of 'cooperite' and the 'braggite/vysotskite' solid-solution series are sufficiently different to facilitate distinction of these platinum group minerals by Raman spectroscopy.
The Service Recovery Paradox in a Call-Center Context: Compensation and Timeliness in Recovering Mobile Customers

After a service failure, customers want to be treated with fairness. They expect the firm to perform quickly without having to wait for the failure resolution. The primary goal of this study is to investigate whether the service recovery paradox (SRP) exists. In addition, the study also explores whether timeliness and compensation can influence it and whether gender differences occur. SRP appears as an important phenomenon to both academics and practitioners because it is seen as an opportunity to achieve higher levels of customer satisfaction through effective service recovery processes. An empirical study of mobile telecommunications customers' complaints, in a call center setting, validated the influence of timeliness and compensation on SPR. It was also found that no differences between men and women were noted on the above relations. Managers must understand that quick failures resolution and compensation will not only enhance customer satisfaction but also prevent potential switching behavior.
Clostridium difficile Infection: A Multicenter Study of Epidemiology and Outcomes in Mechanically Ventilated Patients

Objectives:Clostridium difficile is a leading cause of hospital-associated infection in the United States. The purpose of this study is to assess the prevalence of C. difficile infection among mechanically ventilated patients within the ICUs of three academic hospitals and secondarily describe the influence of C. difficile infection on the outcomes of these patients. Design:A retrospective cohort study. Setting:ICUs at three teaching hospitals: Barnes-Jewish Hospital, Mayo Clinic, and Creighton University Medical Center over a 2-year period. Patients:All hospitalized patients requiring mechanical ventilation for greater than 48 hours within an ICU were eligible for inclusion. Interventions:None. Measurements and Main Results:A total of 5,852 consecutive patients admitted to the ICU were included. Three hundred eighty-six (6.6%) patients with development of C. difficile infection while in the hospital (5.39 cases/1,000 patient days). Septic shock complicating C. difficile infection occurred in 34.7% of patients. Compared with patients without C. difficile infection (n = 5,466), patients with C. difficile infection had a similar hospital mortality rate (25.1% vs 26.3%, p = 0.638). Patients with C. difficile infection were significantly more likely to be discharged to a skilled nursing or rehabilitation facility (42.4% vs 31.9%, p < 0.001), and the median hospital (23 d vs 15 d, p < 0.001) and ICU length of stay (12 d vs 8 d, p < 0.001) were found to be significantly longer in patients with C. difficile infection. Conclusions:Clostridium difficile infection is a relatively common nosocomial infection in mechanically ventilated patients and is associated with prolonged length of hospital and ICU stay, and increased need for skilled nursing care or rehabilitation following hospital discharge.
A Study of 4G Network for Security System

In this paper there is an overview of some standards and security models which are implemented in such an IP-based and heterogeneous networks and we also present some security models in an open environment and finally we obtain that as a result of the nature of 4G networks there are still more security holes and open issues for expert to notice. Our survey shows that a number of new security threats to cause unexpected service interruption and disclosure of information will be possible in 4G due mainly to the fact that 4G is an IP-based, heterogeneous network. Other than that, it tells about the security issues and vulnerabilities present in the above 4G standards are discussed. Finally, we point to potential areas for future vulnerabilities and evaluate areas in 4G security which warrant attention and future work by the research and advanced technology industry.
Semantic analysis of EO-1 hyperion hyperspectral data

In this paper we propose a new method for unsupervised data model discovery in hyperspectral data, by adopting the Latent Dirichlet Allocation (LDA) text modeling tool. The proposed method relies on defining a representation of hyperspectral data that allows LDA analysis, by defining a correspondence between hyperspectral profiles and visual words. As such, we can use Latent Dirichlet Allocation as a method for discovery of latent (intrinsic and natural) meaningful grouping of the spectral bands. Based on the model parameters we propose several use scenarios for hyperspectral data analysis, allowing us to identify semantically meaningful structures in the observed scene. Experiments using the proposed method were carried on an EO-1 Hyperion data set imaging an agricultural area in Romania, acquired in June 2009.

Combining serology and molecular typing of weak D role in improving D typing strategy in Egypt

Rh discrepancies are a problem during routine testing because of partial and weak D phenotypes. Some blood units with weak and partial D expression may escape detection by serology. Limitations of serology can be overcome by molecular typing. The objective of study was to compare currently used serologic methods with molecular analysis to determine the potential application of molecular methods to improve D typing strategies and to estimate the frequency of weak D types among the Arab population.
Predictors of higher technological education graduates’ labour market entrance success

Abstract Nowadays, the successful transition of graduates from university into the world of work is one of the most important priorities of all involved stakeholders: governments, institutions of higher education, and individuals, as well as researchers. The present study analyzes the employability characteristics of higher technological education graduates, focusing on the determination of the factors which significantly affect the quality of their transition in the labour market. Original empirical data was collected through a national survey from 5183 graduates of 11 technological educational institutes (TEIs) of Greek higher education, corresponding to nine broader specialties and 51 professions. The findings of our study indicate that gender (that is, male) and postgraduate studies positively affect graduates’ employment. The interval between graduation and first employment is inversely affected by the duration of bachelor studies, as well as by having children, and appears to depend significantly on the graduate's specialty. Male graduates, parents, postgraduate degree holders, and IT graduates appear to enjoy, on average, higher wages. The match between studies and work is higher for graduates who have children, who have a high or very high bachelor degree mark, for graduates of specialties related to health, as well as for postgraduate degree holders. Relevant suggestions for further research, and the practical implications of this study, are also discussed.

Portfolio Performance Evaluation: the Case of the Portuguese Mutual Funds Market

In this work, we investigate the portfolio performance evaluation of portuguese mutual funds market. For that purpose, we used different models with daily data, where we tested different hypotheses: the existence of alphas with or without selectivity, and the existence of betas with or without timing. There are differences induced by the use of unconditional and conditional models based on non-temporal variation in profitability and risk. The results suggest that fund managers have some capacities of selectivity but not of timing. JEL classification: G11, G23.
Widening the Sphere of Influence: Using a Tool to Extend Extrapersonal Visual Space in a Patient with Severe Neglect

We report evidence that visual representations of space close to the body can be extended when a patient uses a tool to explore the environment. HB had severe neglect of left and far spatial regions which was determined more by how locations were visually perceived than by how they were represented tactilely or through proprioception. His ability to detect visual targets in left and far space was improved, however, when he held a tool. He also had limited tactile/proprioceptive knowledge about the location of his hand. These data suggest that by holding a tool, HB’s more intact representation of near, visual space could be extended to include stimuli presented at a distance from his body. This extension of space improved his detection of visual stimuli. We discuss the implications of the results for the nature of our internal representation of space.
Global branding and strategic CSR: An overview of three types of complexity

Purpose – There is general agreement that global brands should ensure that they incorporate social responsibility. To do this properly, organisations must understand what it means to be socially responsible and how they can leverage their actions. The paper proposes consideration of three distinct areas: the range of social responsibility issues, what the organisations actually do and how to leverage those corporate social responsibility (CSR) actions. This paper seeks to conceptually develop these three areas of complexity – Issue, Organisational and Communication – as it is only after organisations understand these three areas that they can effectively leverage socially responsible activities in their brands.Design/methodology/approach – This research undertakes a review and synthesis of the academic, practitioner and industry literature examining CSR and the brand, addressing the three areas of complexity – issue, organisational and communication.Findings – The research finds that within these three ar.

Using unified theory of acceptance and use of technology, empirical study is conducted on youth to identify determinants and challenges of using social networking sites for intentional social actions. Factor-level study using structural equation modelling showed that effort expectancy, social influence and facilitating condition have significant impact on intentional social action. Implications and scope for future studies are provided for further extension of this study.
Marketing and Supply Chain Management Integration: Strategic Implications for Enhancing Customer Value Proposition

This paper aims to investigate between the renewed emphasis and interests in integration of marketing and supply chain management (SCM) strategies. Providing customer service in the value chain is largely the domain of two functional areas – marketing and SCM. Collaborative integration between these functions is necessary for the firms in gaining competitive advantage. Such firms are more successful in enhancing customer value proposition. This paper shows the advantages of integration between marketing and SCM capabilities and demonstrates how such integration can leverage their strengths. The paper highlights key drivers of marketing and SCM integration and describes detailed processes and mechanisms for achieving such integration in the firms. The prior literature on marketing and SCM integration is reviewed and an evaluation framework is presented which exhibits the benefits of marketing and SCM integration and provides a basis for further empirical validation.
