The Role of International Entrepreneurial Orientation in Successful Internationalization from the Network Capability Perspective

Purpose/Research Question: In general, networks have played a role in improving innovation, and early-stage companies adopt an entrepreneurial orientation to secure competitiveness. In other words, the companies would like to penetrate global markets due to the CEO’s international entrepreneurial orientation. In addition, by utilizing their networks, the companies would like to improve their international performance. Relatively few studies have been devoted to investigating the empirical relationships between entrepreneurial orientation, networks, and international performance. In particular, technology-based firms are one of the best samples. Therefore, this study aims to explore the characteristics of the firms and then investigate comprehensively and empirically the relationships between international entrepreneurial orientation, networks, and international performance, based on data from technology-based firms in South Korea. Design/Methodology/Approach: The study analyzes data from technology-based small and medium-sized enterprises (SMEs) using structural equation modeling (SEM). It assumes that networks will play a moderating role in the relationships between international entrepreneurial orientation and international performance. We carried out the survey after conducting interviews with CEOs of SMEs. Findings/Results: International entrepreneurial orientation has a significant effect on international performance. Moreover, the stronger the networks that SMEs have with other stakeholders such as universities, industries, and technoparks, the higher their international performance. With stronger networks, tech-based SMEs have easier access to useful technologies and hence better international performance. Research Limitations/Implications: There are some limitations to this study. First of all, the study relied heavily on quantitative methods, such as surveys. This approach is inadequate for considering individuals’ in-depth opinions. Therefore, future research utilizing both qualitative and quantitative measures needs to be carried out. Second, this study has some academic limitations. In fact, this study considered restricted factors regarding innovation and networks; thus it is necessary to evaluate other variables such as environmental factors (e.g., regulations or support policies) that might be significantly associated with networks and innovation hereafter. Finally, due to the fact that this study was focused on SMEs, it is difficult to generalize the above results. However, this study implies that stronger network ties improve international performance, thus SMEs must establish and reinforce networks to improve the performance.
andDissertations 2011 3 D geometry compression with Holoimage

Holoimage is a technique that is capable of compressing 3D geometry scans into 2D images. The main goal of this thesis was to develop a way to compress 3D geometry coming from a structured light scanner into a manageable format. Structured light scanners have made the acquisition and display of 3D data simple. Recently an area of 3D scanning has emerged called realtime 3D scanning, which allows for the capture, reconstruction, and display to be realized in 3D. With these advancements comes the challenge of working with the large volume of data that comes from such a scanner. In an uncompressed format, these realtime 3D scanners can have data rates surpassing 400 MB/s. For realtime applications, this amount is unmanageable, thus a method to compress the data must be found. Holoimage is a technique that was developed to compress data from such a scanner, converting the raw 3D geometry into 2D images which can then be compressed using 2D image compression techniques. This conversion from 3D to 2D is achieved through a virtual structured light scanner, which is similar to an actual structured light scanner with some key differences. In the virtual system, traditional sources of error such as lighting, camera properties, and system calibration can be controlled to provide an ideal scanning system. Thus, unlike traditional structured light systems, Holoimage does not suffer from disadvantages such as the inability to measure discontinuous surfaces or surfaces with large step height variations. Also, the Holoimage technique is constructed in such a way that all of the steps are pixel operations, thus it can be run on parallel hardware such as a graphics processing unit (GPU).
Perceived Intelligence and Protégée Effect in a Techable Agent Software

Studies have shown that the “teachable agent” paradigm, i.e. “learning-by-teaching” using teachable virtual agents in educational software, benefits learning by increasing students’ sense of responsibility and supporting metacognition (see for instance Schwartz et al. (2009) and Biswas et al. (2005)). The “protégée effect” is a theoretical concept that describes the beneficial factors of the teachable agent paradigm in that the student makes larger learning efforts when the goal is to teach an agent than when the goal is to learn for themselves (Chase, Chin, Oppezzo & Schwartz, 2009). The authors hypothesize that the following three mechanisms lead to the increased effort of learning: a feeling of responsibility towards the teachable agent, an adoption of an incrementalist view of knowledge, and a protection of their ego since it is the agent that is tested for its learning and potentially fails.
Mechanics of Crystalline Nanowires: An Experimental Perspective

A wide variety of crystalline nanowires (NWs) with outstanding mechanical properties have recently emerged. Measuring their mechanical properties and understanding their deformation mechanisms are of important relevance to many of their device applications. On the other hand, such crystalline NWs can provide an unprecedented platform for probing mechanics at the nanoscale. While challenging, the field of experimental mechanics of crystalline nanowires has emerged and seen exciting progress in the past decade. This review summarizes recent advances in this field, focusing on major experimental methods using atomic force microscope (AFM) and electron microscopes and key results on mechanics of crystalline nanowires learned from such experimental studies. Advances in several selected topics are discussed including elasticity, fracture, plasticity, and anelasticity. Finally, this review surveys some applications of crystalline nanowires such as flexible and stretchable electronics, nanocomposites, nanoelectromechanical systems (NEMS), energy harvesting and storage, and strain engineering, where mechanics plays a key role.

Quiescin Sulfhydryl Oxidase 1 (QSOX1) Secreted by Lung Cancer Cells Promotes Cancer Metastasis

As lung cancer shows the highest mortality in cancer-related death, serum biomarkers are demanded for lung cancer diagnosis and its treatment. To discover lung cancer protein biomarkers, secreted proteins from primary cultured lung cancer and adjacent normal tissues from patients were subjected to LC/MS–MS proteomic analysis. Quiescin sulfhydryl oxidase (QSOX1) was selected as a biomarker candidate from the enriched proteins in the secretion of lung cancer cells. QSOX1 levels were higher in 82% (51 of 62 tissues) of lung cancer tissues compared to adjacent normal tissues. Importantly, QSOX1 serum levels were significantly higher in cancer patients (p < 0.05, Area Under curve (AUC) = 0.89) when measured by multiple reaction monitoring (MRM). Higher levels of QSOX1 were also uniquely detected in lung cancer tissues, among several other solid cancers, by immunohistochemistry. QSOX1-knock-downed Lewis lung cancer (LLC) cells were less viable from oxidative stress and reduced migration and invasion. In addition, LLC mouse models with QSOX1 knock-down also proved that QSOX1 functions in promoting cancer metastasis. In conclusion, QSOX1 might be a lung cancer tissue-derived biomarker and be involved in the promotion of lung cancers, and thus can be a therapeutic target for lung cancers.
Making the Coupled Gaussian Process Dynamical Model Modular and Scalable with Variational Approximations †

We describe a sparse, variational posterior approximation to the Coupled Gaussian Process Dynamical Model (CGPDM), which is a latent space coupled dynamical model in discrete time. The purpose of the approximation is threefold: first, to reduce training time of the model; second, to enable modular re-use of learned dynamics; and, third, to store these learned dynamics compactly. Our target applications here are human movement primitive (MP) models, where an MP is a reusable spatiotemporal component, or “module” of a human full-body movement. Besides re-usability of learned MPs, compactness is crucial, to allow for the storage of a large library of movements. We first derive the variational approximation, illustrate it on toy data, test its predictions against a range of other MP models and finally compare movements produced by the model against human perceptual expectations. We show that the variational CGPDM outperforms several other MP models on movement trajectory prediction. Furthermore, human observers find its movements nearly indistinguishable from replays of natural movement recordings for a very compact parameterization of the approximation.
Evidence for Selective Caching by Arctic Ground Squirrels Living in Alpine Meadows in the Yukon

Male arctic ground squirrels ( Spermophilus parryii ) rely on food they cached the previous year for the energy they need to compete for mates each spring. We collected cheek-pouch contents of arctic ground squirrels trapped during three summers (2000–02) as an indication of what squirrels cached. Among adults, both males and females carried material in their cheek pouches, but males did so more frequently than females (4.4% vs. 0.6% of captures). Males carried material later in the summer than females, and also carried different material (seeds and rhizomes as opposed to nesting material). These differences probably reflect different purposes of cheek-pouch contents—females carried material for immediate use, whereas males carried food for caching. Only 24 of over 100 species of vascular plants growing at our alpine study site were carried, and presumably cached, by male arctic ground squirrels. The seeds or rhizomes of one species, Polygonum viviparum , were found in over 90% of cheek-pouch contents examined, even though that species grew at relatively low density and was no more common than another species in the same genus ( Polygonum bistorta ) that was never found in cheek-pouch contents. Collectively, this evidence indicates that males are highly selective in what species they cache. Many of the species carried by arctic ground squirrels in this study have also been found in Pleistocene fossil caches from central Yukon, indicating that food preferences of this species may have remained stable over time.
Running Head: FACILITATING ATTENTIVE BEHAVIOR The Effects of a Response-Cost Program on the Classroom Behavior of Two Children with Attention Deficit /Hyperactivity Disorder

This study examines the effects of using response cost in combination with positive reinforcement procedures in helping two second grade students with attention deficit hyperactivity disorder maintain their attention in the classroom. This involved the loss of reinforcers/points contingent upon inappropriate behavior in the classroom, in addition to earning them for appropriate behavior. The Conners Teacher Rating Scale was used to assess behavior. A small plastic box which contained a digital counter on its face and a red light on top was placed on each subject's desk, and each minute a point was automatically awarded to the child on the counter display. The teacher carried a transmitter and when the student was observed to be off-task, not working, or disruptive, the desk unit was signaled, the red light on the student's desk came on, and a point was deducted. Points could be exchanges for extra computer time, school store items, or a chance to be the teacher's helper. The results indicate that measures of hyperactivity for both subjects showed significant decreases from baseline to end of treatment phases. Significant decreases also occurred in measures of conduct problems and emotional indulgence for one child. (Contains 14 references.)

Phenotypic Assays for Detection of Extended Spectrum Β-Lactamases and Carbapenemases: A Laboratory Guide for Microbiologists

This review aimed at defining and classifying extended spectrum β-lactamases, ESBLs and carbapenemases, summarizing the different phenotypic methods used to detect production of these enzymes in clinically significant gram negative bacteria and also describing the methods that discourse challenges mostly encountered during detection of these enzymes in microbiology laboratories with the purpose of formulating recommendations on best practice to screen for these enzymes. We conclude that the modified double disk synergy, MDDS is not only suitable for the confirmation of ESBL production after screening isolates with the cephalosporin/clavulanate combination disc diffusion or broth micro-dilution methods but also distinguishes ESBL production and over-expression of AmpC-derepressed mutants and as well serves as an indicator for AmpC screening. Furthermore, we suggest cefotaxime, ceftazidime and cefpodoxime (for testing using a single drug) as indicator antibiotics of choice for ESBL detection. The MDDS and cefoxitin/AmpC inhibitor combination disc method, using cloxacillin and phenylboronic acid can be used as screening tests for AmpC production and either the AmpC disc test, the disc approximation test or the modified three dimensional extract test as confirmatory tests for AmpC production. We also suggest that confirmation of carbapenemase production be done with the modified hodge test, using Klebsiella pneumoniae ATCC 700603 as the indicator organism or the modified carbapenem inactivation method. However, to differentiate between the different classes of carbapenemases, boronic acid and EDTA based methods (double-disk synergy tests and combined-disk tests) using imipenem, meropenem and ertapenem, in combination with 3-aminophenylboronic acid and ethylene diamine tetra acetic acid be used.
Levels of Cadmium, Lead, Mercury and 137caesium in Caribou ( Rangifer tarandus ) Tissues from Northern Québec

Levels of cadmium (Cd), lead (Pb) and total mercury (Hg) were assessed in samples of muscle, kidney, and liver from caribou ( Rangifer tarandus ; n = 317) harvested in two regions of northern Quebec between 1994 and 1996. Levels of 137caesium (137Cs) were also examined in muscle samples. Log concentration of the three metals varied significantly among tissues and was lowest in diaphragm muscle and highest in kidneys and liver. Mean Cd (wet weight, w.w.) concentration was 0.01 µg/g in muscle, 7.69 µg/g in kidneys and 1.13 µg/g in liver. Levels of Cd exceeded tolerance thresholds for human consumption in nearly all kidney samples and in nearly half the liver samples. Mean Pb concentration (w.w.) was 0.05 µg/g in muscle, 0.26 µg/g in kidneys and 0.95 µg/g in liver, with few samples exceeding consumption thresholds. Mean total Hg concentration (w.w.) in muscle was 0.03 µg/g, 1.26 µg/g in kidneys and 0.67 µg/g in liver, with concentrations exceeding consumption thresholds in most kidney samples and nearly half the liver samples. Regional differences occurred in log concentration of the three metals for most tissues, with the western region consistently showing higher values. Mean log Cd and Pb concentrations increased with age in kidneys, but log Pb decreased with age in muscle samples. Interactions between month of collection and sex and region also occurred for some metals in some tissues. Mean level of 137Cs in muscle samples was 94.7 Bq/kg, never exceeding the acceptable limit for human consumption.
Bioavailable Mercury in Arctic Snow Determined by a Light-Emitting mer-lux Bioreporter

The initial objective of this component of my research was to determine the bioavailability of Hg(II) in snow entering the Arctic via long-range atmospheric transport. In addition to samples for bioHg, snow samples were collected for total Hg, Me Hg, and major cation chemistry. Polar sunrise at Barrow is in late January, and the melt period begins in June. Samples were therefore collected before Polar sunrise in January and after Polar sunrise in March, May, and June 2000. BioHg was undetectable in Barrow snow in January, and total Hg concentrations were low. BioHg then increased from 0.22 ng/L (~1% of total Hg) in March to 8.8 ng/L (nearly 13% of the total Hg) in May (Fig. 2). (Rarely have the environmental samples that I have analyzed exceeded 0.5 ng/L.) Our June snow sample was taken just before the intensive snowmelt period began, so the snow was slushy but not melted. BioHg had decreased to 2.9 ng/L, which is still very high for a remote area. Furthermore, this concentration represented over 50% of the total Hg in Barrow snow. Because Barrow has sunlight 24 hours a day during the melt period, melting occurs over a relatively short time. If these concentrations of bioHg are sustained during this period, a very large pulse must be entering the ecosystem in the spring. (We will be examining the melt period more intensively in 2001; see below.) An interesting and unexpected finding was that during Polar sunrise, MeHg also increased to concentrations commonly found in boreal wetlands where it is biotically produced. The mechanism of MeHg formation in the Arctic atmosphere is as yet unknown; however, we hypothesize that it could involve the demethylation of dimethyl mercury (diMeHg) produced biogenically in the ocean.
Values as the point of a story

Stories can be powerful vehicles of persuasion, because they convince not by imparting facts and rules, but rather by encouraging the right choices through a change in values. In this article I intend to lay the conceptual foundations for a mature theory of stories for value-based argumentation. The article discusses how stories can be used in argumentation, and how values can be seen as the point, or the conclusion, of
Cadmium Exacerbates Acetic Acid Induced Experimental Colitis in Rats

Background: Increase in the incidences of inflammatory bowel disease (IBD) in developing countries is a pointer to the role metal toxicants may play in its pathogenesis. Cadmium (Cd) has been implicated in the etiology of diseases involving several tissues including the colonic mucosa. This present study aimed at investigating the effects of oral cadmium exposures on healing of acetic acid (AA)-induced colitis in rats. Methods and Findings: Male Wistar rats (100-120 g) were grouped and exposed to cadmium as follows: Control (water), Cd25 (25 ppm CdCl2), Cd50 (50 ppm CdCl2), Cd100 (100 ppm CdCl2) for four weeks. Colitis was induced by intrarectal administration of 2 ml 4% acetic acid. Rats were sacrificed and colons were resected on days 0, 3, 7 and 14 of colitis induction. Weekly body weight, diarrheal and macroscopic scores, organ weights, neutrophil/lymphocyte ratio (NLR), malondialdehyde (MDA) concentration, and regeneration in colonic tissues were studied microscopically. Cadmium significantly (p<0.05) decreased weight gain (%) at weeks 3 and 4 in Cd100 group, significantly (p<0.05) increased stool consistency scores on day 5 in Cd100 group, increased colon macroscopic scores in Cd100 group on days 3 and 7, significantly (p<0.05) increased neutrophil/ lymphocyte ratio on days 0 and 7 in Cd50 and Cd100, and colonic MDA concentrations in each of Cd25, Cd50 and Cd100 from day 3 till day 14. Colon histopathology persisted till day 14 in Cd100 group. Conclusions: These data indicate that cadmium delayed healing of acetic acid induced colitis and inflammatory pathways may be implicated.
Towards an Integrated Approach to Food Behaviour: Meat Consumption and Substitution, From Context to Consumers

Background: Human diet is increasingly acknowledged as a critical issue in global health and sustainability challenges. Aim: This article draws on meat consumption and substitution to illustrate how two features facilitate an integrated approach to understanding food behaviour: (1) framing such behaviour in a wider historical, sociocultural and environmental context; and (2) acknowledging the role that psychological processes play in consumer willingness and propensity to engage in a given diet. Conclusion: To mobilize large-scale changes towards healthier and more sustainable dietary choices, the article concludes with a call for developing conceptual, methodological and delivery tools that: (1) consider the context in which food habits take place; and (2) identify and engage with different groups of consumers.
Assessing the diversity of phytotelmic frogs along Madagascar’s east coast: Redefinition of Guibemantis bicalcaratus (BOETTGER, 1913) and revalidation of Guibemantis methueni (ANGEL, 1929)

Guibemantis bicalcaratus (Boettger, 1913) has been considered as a widespread member of the subgenus Pandanusicola of largely phytotelmic-breeding Malagasy frogs. Based on new collections from its type locality, the Malagasy island Nosy Boraha, and several other localities on Madagascar’s east coast, we revise the status of G. bicalcaratus using molecular and morphological data. Mitochondrial DNA sequences of the 16S rRNA gene demonstrate the presence of two deep genealogical lineages of Pandanusicola on Nosy Boraha. Of these, one so far has only been found on Nosy Boraha whereas the second is also present at several other localities along the central east coast of Madagascar. Specimens assigned to the two mtDNA lineages did not share alleles in sequences of the nuclear RAG1 gene except for one specimen, suggesting reduction or absence of gene flow despite sympatry, with occasional hybridization. No differences between the two lineages were found in external morphology but faint differences in color allowed us to discriminate the majority of specimens, and we therefore conclude that they should be considered as belonging to two distinct species. Based on these chromatic differences and comparison with type specimens, we assign the species present only on Nosy Boraha to Guibemantis bicalcaratus whereas the second species also occurs at Ambila, the type locality of Gephyromantis methueni Angel, 1929. We consequently resurrect this nomen as Guibemantis methueni for this species. It is likely that the two species are restricted to relatively small ranges on Madagascar’s central east coast, but due to the rudimentary knowledge on their distribution and habitat requirements we suggest a threat status of Data Deficient for both of them.
