The Evolution of Strategic Emerging Industry: The Earlier Stage and the Shake-Out Phenomenon

The industrial landscape is becoming increasingly complex and dynamic, with innovative technologies stimulating the emergence of new industries. Literatures searching life cycle always describe a smooth pattern of emergence over time in which the number of firms in an industry increases, hits a peak, decreases as a result of a shakeout, and then stabilizes as the industry reaches maturity. When these findings applied to the strategic emerging industry the life cycle curve need modified according the industries' characteristics. This paper introduces an alternative pattern of evolution of strategic emerging industries in the earlier stage. Two phases are added in the process and the time axis extended into five phases. During the earlier stage, an industry experiences a sharp decrease in the number of firms - a "mini shakeout" - before increasing again, reaching a final peak and undergoing a major shakeout as described in the extant literature. We then propose a conceptual model that highlights the role of unexpected factors, the internal factors and strategic importance of the emerging industry to the firm in determining its likelihood of exit from the industry.
In vitro and in vivo degradation of bioabsorbable PLLA spinal fusion cages.

The in vitro and in vivo degradation of poly-L-lactic acid cages used as an adjunct to spinal arthrodesis was investigated. In the in vitro experiments cages were subjected to aging up to 73 weeks in phosphate-buffered solution (pH 7.4) at 37 degrees C. Inherent viscosity, crystallinity, and mechanical strength were determined at different time points. In the in vivo study, the poly-L-lactic acid cages were packed with bone graft and implanted in the L3-L4 spinal motion segment of 18 Dutch milk goats. At 12, 26, and 52 weeks, the motion segments were isolated and poly-L-lactic acid samples retrieved. On evaluation, the in vivo implanted cages showed an advanced decline in inherent viscosity compared to the cages subjected to in vitro degradation experiments. At 6 months of implantation, the geometrical shape and original height of 10 mm was maintained during 6 months of follow up. This finding fits well with the observation that mechanical strength was maintained for a period of 6 months in vitro. At 12 months, the poly-L-lactic acid cage had been disintegrated into multiple fragments with signs of absorption. Despite the high-load-bearing conditions, the poly-L-lactic acid cage allowed interbody fusion to occur without collapse of the cage.
Co-existence of learners and stayers maintains the advantage of social foraging

Question: To what extent can learning facilitate group formation in a social forager? Model features: An individual-based simulation model is used to explore frequency- and density-dependent interactions between mobile learners and non-selective stayers that forage in a patchy resource environment. Key assumption: Foraging efficiency peaks at intermediate group sizes. Conclusions: Frequency-dependent interplay between mobile learners and sedentary stayers represents a general mechanism of group formation that maintains the advantage of social foraging. When rare or at moderate frequencies, learners redistribute and aggregate in groups of optimal size. This enhances the foraging performance of both learners and stayers. When the learning strategy dominates in the population, group size dynamics become unstable, resource intake for learners drops, and stayers do best. The strategies mutually benefit from each other and may potentially co-exist.
Feather pecking in laying hens

Feather pecking (FP), pecking at and pulling out the feathers of conspecifics, is an unwelcome behaviour with both welfare and economic implications for the laying hen (Sedlackova et al., 2004). It is painful, increases a bird’s susceptibility to further pecking and cannibalism, and is considered an indicator of reduced welfare in both victim and performer (Bestman & Wagenaar, 2003). FP is thought to be a form of redirected behaviour, and there are studies linking it variously with feed/ground pecking, dust-bathing, or socially related pecking (Su et al., 2005). The development of FP is also related to environmental factors such as flock size, stocking density, floor substrate availability, light intensity, diet, temperature and access to elevated perches, as well as endogenous characteristics such as sex, age and reactions to frustration or stress (Sedlackova et al., 2004; Bestman & Wagenaar, 2003). The increased risk of FP in alternative housing systems, which otherwise have a number of welfare advantages over battery systems, is one of the main barriers to their widespread adoption (Sedlackova et al., 2004). Advances in the understanding and prevention of FP are thus of considerable welfare significance for laying hens.
Alcohol-related problems among black, Hispanic and white men: the contribution of neighborhood poverty.

OBJECTIVE We examined the cross-sectional relationships between race/ethnicity, neighborhood poverty and alcohol-related problems among black, Hispanic and white male drinkers. Test hypotheses were that black and Hispanic men living in more impoverished neighborhoods would report increased numbers of alcohol-related problems than comparable white men. METHOD Study hypotheses were tested in a sample of 744 black, Hispanic and white men participating in the 1992 National Alcohol Follow-up Survey. Study hypotheses were analyzed using generalized linear model regression analysis. RESULTS Neighborhood poverty had a greater effect on alcohol-related problems in black than in white men, partially supporting our hypothesis. Black men living in more impoverished neighborhoods reported greater numbers of alcohol-related problems than comparable white men; there were no race differences among more affluent men. Neighborhood poverty had little effect on alcohol-related problems in Hispanic men. CONCLUSIONS Findings suggest that, giving unfavorable economic conditions, black men will report greater numbers of alcohol-related problems than comparable white men.
POSTPARTUM RESOLUTION TIME OF PROTEINURIA IS A GOOD PREDICTOR FOR POOR MATERNAL OUTCOMES IN PREECLAMPSIA

Results: The mean resolution time of proteinuria was 3 days; 3.5 days in the SPE group and 2.1 days in the NSPE group (p=0.002). The resolution time of proteinuria had a good predictive value for poor maternal outcome with an ROC-AUC of 0.73 (95% CI 0.59–0.88; p=0.002), the sensitivity and specificity were 62.5% and 80.2%, respectively. Proteinuria lasted longer than 3 days related with a higher risk of poor maternal outcomes. The ROCAUC value of the resolution time of proteinuria for severe preeclampsia was found to be 0.70 (95% CI 0.61–0.80; p = 0.001). The sensitivity and specificity were 72.1% and 63.5%, respectively. Amount of proteinuria at diagnosis had a statistically significant relationship with the presence of proteinuria at discharge (OR 2.70; 97.5% CI 1.32–6.02; p = 0.0096).
Activity of (+)-cyclaradine (Sch 31172) against herpes simplex virus in vitro and in vivo

(+)-Cyclaradine (Sch 31172) is the carbocyclic derivative of adenosine arabinoside (9-beta-D-arabinofuranosyladenine). Because it is not deaminated by deaminase in serum, as is adenosine arabinoside, (+)-cyclaradine is about 2 to 5 times more active in vitro against herpes simplex virus. (+)-Cyclaradine has in vitro activity nearly equivalent to that of phosphonoformate but is significantly less active than acycloguanosine (acyclovir; ACV), trifluorothymidine, or 9-(1,3-dihydroxy-2-propoxymethyl)guanine. The absolute ratios of in vitro activities are difficult to determine because of variability among virus strains, inoculum size, and dependence on the tissue culture cell line in which the comparative test is carried out. (+)-Cyclaradine is active against TK-, ACV-resistant mutants. In the guinea pig model of vaginal herpes simplex virus infection, (+)-cyclaradine is only slightly less active than ACV when both molecules are nearly equivalently bioavailable; thus, the large difference in activity seen in vitro is not reflected in this in vivo model system.
Oportunidades de innovación divergentes: ¿es el territorio importante?

En este trabajo investigamos si existen diferencias regionales en las oportunidades para la innovacion en Argentina y que caracteristicas regionales explican estas diferencias. Utilizando datos a nivel firma de la Encuesta Nacional de Innovacion 2004, asi como informacion agregada correspondiente a las jurisdicciones del pais, aplicamos un modelo multinivel a fin de evaluar las fuentes regionales de las oportunidades para innovar de las firmas industriales argentinas. Los resultados indican que si bien la efectividad del gasto en innovacion es mayor en las jurisdicciones centrales que en el resto del pais, las diferencias regionales se reducen notablemente si se controla por la heterogeneidad en la conducta individual de las empresas. Estas pequenas diferencias regionales en las oportunidades de innovacion estan asociadas principalmente a diferencias en la demanda externa que enfrentan las jurisdicciones. En el articulo discutimos algunas de las razones que podrian explicar nuestros resultados y las implicancias para la investigacion futura y la politica.
Classification of cardiotocographic records by neural networks

Antepartum fetal monitoring based on the classical cardiotocography (CTG) is a noninvasive and low-price tool for checking fetal status. Its introduction in the clinical routine limited the occurrence of fetal problems leading to a reduction of the precocious child mortality. Nevertheless very poor indications on fetal pathologies can be inferred from the actual CTG analysis methods, either they consist of the clinician eye inspection or of automatic algorithms. A relevant amount of this unsatisfactory performance resides on the weakness of methods used for classifying fetal conditions and generate a risk alarm during pregnancy. In the paper three neural classifiers are proposed to discriminate among fetal behavioral states and among normal and pathological fetal conditions, on the basis of CTG recordings. All classifiers are fed by indexes extracted from fetal heart rate signal. Results show very promising performance towards the prediction of fetal outcomes on the set of collected FHR signals.
A case study of teachers' professional learning: Becoming a community of professional learning or not?

This paper describes a school's participation in a project designed to support critical reflection of teachers' beliefs about best practice in early childhood education, and how these beliefs and practices intersected with shifting policies and trends in the broader early childhood field. The "Professional Learning" Project (PL project), was conducted in collaboration with a local university. As the project unfolded, multiple influences were found to affect its ultimate outcomes, including the tensions associated with day-to-day classroom commitments and varying levels of willingness to engage in what were at times confronting and challenging discussions. As a result, engagement, collaboration and participation ebbed and flowed. metropolitan primary school, to reflect on their early childhood practice, at a time when there were changing policies and practices at the national level. Berrivale Primary School conducted this process in partnership with a local university with which it had a well-established relationship. A feature of this partnership was the allocation of a university colleague to the school whose role was to build equitable, respectful relationships and collaboration for mutual benefit. It was through this relationship that the Professional Learning Project (PLP) reported in this case study was developed. The deputy school principal and two university researchers were the co-facilitators of the project that spanned one and a half years. The aim of the PLP was to facilitate Kindergarten to Year 3 teachers' exploration of their perceptions, knowledge and understanding of early childhood pedagogy; the extent to which these matched national policies and agendas; and the development of a shared view amongst staff of effective early childhood practice. The outcome for the school was to be a process that facilitated professional development for staff, and a policy statement outlining principles of practice and guidelines for implementation at various ages and stages from Kindergarten to Year 3. The university researchers facilitated the professional learning experiences and acted as participant observers in the project. In this paper, we provide background and contextual information, a description of the methodology, and a discussion of key findings of the collaborative project. Background and context
Analysis on interference of DS-UWB signal to narrowband systems

The power of ultra-wideband (UWB) signals has an extremely large frequency bandwidth which is a potential interference to narrow band systems. So UWB systems must obey the rules of frequency management of FCC when share frequency resources with traditional narrowband systems. It's presented the analysis of power spectral density (PSD) of direct sequence code UWB (DS-UWB) signals and some key factors of interference power of DS-UWB signals. It's studied that the relationship between envelop of DS-UWB PSD and energy spectral density (ESD) of pulse waveform and that among continuous and disperse components of PSD, modulated sequences and pulse repetition frequency (PRF). It's shown that some pseudo-random codes with suitable properties and parameters can reduce the interference power of DS-UWB signals to narrowband systems. Simulations have been done to prove it in this paper
Pancreas Transplantation in African American Patients Using Basiliximab Induction

The long-term outcome of pancreas transplant (PT) in African Americans (AA) using interleukin-2 receptor antibody induction has not been well documented. We retrospectively analyzed the 7-year outcomes of 45 AA and 73 white recipients of primary PT at our center. All PT were performed with enteric-systemic drainage. Basiliximab induction, tacrolimus, mycophenolic acid, and steroid maintenance were used as the primary immunotherapy. There was no difference by Kaplan-Meier analysis in patient (P = 0.94), pancreas graft (P = 0.76), or death-censored graft survival (P = 0.71) over 7 years between the AA and white groups. Clinically treated pancreas rejection episodes were slightly higher in AA than in white patients. Similarly, cytomegalovirus infection rates and comparable quality of graft function were noted in both groups over 7 years. Excellent long-term patient and pancreas graft survivals can be achieved in AA recipients of PT by using interleukin-2 receptor antibody induction and combination of tacrolimus, mycophenolic acid, and steroid maintenance.
Anti‐C1q Autoantibodies in Lupus Nephritis: Prevalence and Clinical Significance

Abstract: Recently, anti‐C1q autoantibodies have been proposed as a useful marker in systemic lupus erythematosus (SLE) since their occurrence correlates with renal involvement and, possibly, with nephritic activity. We aimed to evaluate the prevalence of anti‐C1q antibodies in patients with SLE, with and without renal involvement, and to correlate these markers' presence and levels with the activity of the disease and nephropathy. We studied 61 patients with SLE, 40 of whom had biopsy‐proven lupus nephritis; 35 patients with other connective tissue diseases; and 54 healthy controls. In addition, 18 lupus nephritis patients were followed up during the disease time course. Anti‐C1q antibodies were measured using “homemade” ELISA with high salt concentration (1 M sodium chloride). High anti‐C1q antibody titers (> 55 AU) were present in 27 of 61 (44%) SLE patients and in 4% and 0% of normal blood donors and pathologic controls, respectively. Anti‐C1q antibodies were found in 60% of patients with lupus nephritis compared with only 14% of SLE patients without nephropathy (P < 0.05). Moreover, patients who were positive for anti‐C1q antibodies had a higher European Consensus Lupus Activity Measurement (ECLAM) score (4.35 vs. 2.2); 89% of patients with active lupus nephritis showed high titers of anti‐C1q antibodies compared with 0% of patients with inactive nephritis. Anti‐C1q and anti‐dsDNA antibodies agreed in 79% of cases. Our results confirm that anti‐C1q antibodies are present in a significant percentage of SLE patients, and that their presence and levels correlate with disease activity—in particular, during renal flare‐ups.
Technik natürlich nutzen - NUI-Design in der Praxis

Was steckt hinter einer Benutzungsschnittstelle wie der des Apple iPhone, des HTC Sense oder des Microsoft Surface? Bei Natural User Interfaces (NUI) bedienen Nutzer die Oberfläche mit den Händen und knüpfen dabei an bereits vorhandenes Wissen an. Eine Studie untersuchte, wie Nutzer mit der gestenbasierten Bedienung zurechtkommen. Dabei wurde nicht nur getestet, wie leicht oder schwer einzelne MultitouchInteraktionen den Testpersonen fallen, sondern auch, ob es Unterschiede zwischen älteren und jüngeren Nutzern gibt. Das Ergebnis der Studie zeigt, dass die Bedienung von NUI-Oberflächen für Nutzer jeden Alters leicht zu verstehen ist und eine sehr niedrige Einstiegshürde hat, auch wenn diese für ältere Nutzer geringfügig höher liegt. Bei einer Erhebung nannten Nutzer am Häufigsten die gestenbasierte Bedienung auf die Frage, was sie am iPhone am meisten fasziniert. Doch was Nutzer begeistert, stellt Entwickler und Designer vor neue Herausforderungen: Multitouch, Multi-User, Objekterkennung, 360°-Interface. Anhand einer Anwendung für den Multitouch-Tisch MS Surface, zeigt der Beitrag beispielhaft, was bei der Gestaltung von NUI-Oberflächen beachtet werden muss, welche Besonderheiten zu berücksichtigen sind und welches Vorgehen bei der Entwicklung zu empfehlen ist.

A student teacher's recontextualisation of teaching mathematics using ICT

In university mathematics education courses, messages about the pedagogy and content of teaching mathematics are conveyed to student teachers. During the teaching practicum, mentor teachers also have their own set of messages about mathematics teaching. My research investigates the messages conveyed to student teachers and the ways student teachers acknowledge these messages and incorporate them into their teaching using the notion of recontextualisation. The use of information and communication technology (ICT) in teaching mathematics is generally viewed positively in the university and by mentor teachers. In this paper I share some data and analysis of the messages about ICT, and how one student teacher recontextualises these messages into his own teaching of mathematics.
ARCHIVAL OBSERVATIONS OF ACTIVE ASTEROID 313P/GIBBS

We present prediscovery observations of active asteroid 313P/(2014 S4) Gibbs taken in 2003 and 2004. Sloan Digital Sky Survey observations from 2003 establish that, after 133P/Elst–Pizarro and 238P/Read, 313P is only the third main-belt active asteroid to show mass loss in different orbits. This repetitive activity is consistent with mass loss driven by the sublimation of ice. A Finson-Probstein model is used to analyze the morphology of the object, showing that the activity was continuous but declining steadily over two months of observation in 2003. Ejected dust particles are dominated by relatively large sizes with radii from ∼25 to ∼600 μm. We estimate from photometry the dust mass loss rate to be ≲ 0.2 ? > kg s−1. In contrast, Subaru telescope observations from 2004 show no evidence for mass loss and suggest a bare nucleus. The color, nucleus size, and the mass loss rates of 313P measured in 2003 are consistent with published values obtained from data taken in 2014. However, the effective cross-section was larger than in 2014 by a factor of ∼2, indicating a decline in the activity between orbits. A new orbital solution gives a 5σ upper limit to the transverse non-gravitational parameter A 2 ≲ 2.45 × 10 − 8 ? > AU day−2.
Primary chromohifomycosis of the nasal septum

Chromohyphomycosis, also known as chromoblastomycosis, is a disease that affects body areas unprotected by clothing; the lower limbs are the most affected.1 The nasal cavity is rarely affected by chromoblastomycotic lesions, and there have been only three cases described in this region.1-3 This infection is caused by a variety of fungi, which display a dark green color on the surface of culture medium due to the hyphal layer, and are almost black in depth. These fungi are called Dematiaceous and have a brownish color in the histological analysis, when stained with hematoxylin-eosin (HE). 4 Septal chromohyphomycosis is rare, and its diagnosis is based on histopathological analysis and culture.5
Radiation-induced genomic instability and bystander effects: related inflammatory-type responses to radiation-induced stress and injury? A review

Purpose : To review studies of radiation responses in the haemopoietic system in the context of radiation-induced genomic instability, bystander effects and inflammatory-type processes. Results : There is considerable evidence that cells that themselves are not exposed to ionizing radiation but are the progeny of cells irradiated many cell divisions previously may express a high frequency of gene mutations, chromosomal aberrations and cell death. These effects are collectively known as radiation-induced genomic instability. A second untargeted effect results in non-irradiated cells exhibiting responses typically associated with direct radiation exposure but occurs as a consequence of contact with irradiated cells or by receiving soluble signals from irradiated cells. These effects are collectively known as radiation-induced bystander effects. Reported effects include increases or decreases in damage-inducible and stress-related proteins; increases or decreases in reactive oxygen species, cell death or cell proliferation, and induction of mutations and chromosome aberrations. This array of responses is reminiscent of effects mediated by cytokines and other similar regulatory factors that may involve, but do not necessarily require, gap junction-mediated transfer, have multiple inducers and a variety of context-dependent consequences in different cell systems. That chromosomal instability in haemopoietic cells can be induced by an indirect bystander-type mechanism both in vitro and in vivo provides a potential link between these two untargeted effects and there are radiation responses in vivo consistent with the microenvironment contributing secondary cell damage as a consequence of an inflammatory-type response to radiation-induced injury. Intercellular signalling, production of cytokines and free radicals are features of inflammatory responses that have the potential for both bystander-mediated and persisting damage as well as for conferring a predisposition to malignancy. The induction of bystander effects and instabilities may reflect interrelated aspects of a non-specific inflammatory-type response to radiation-induced stress and injury and be involved in a variety of the pathological consequences of radiation exposures.
