Innovation success: What is the role of innovation strategies?

The objective of this paper is to explore the role played by firms' strategies during innovation process and its effects on innovation success. We argue that firm's innovative decisions not only concern how much innovation effort to make but, more especially, what kind of innovation objectives to pursue, which refer to strategic decisions taken at the level of the firm. Our econometric analysis is based on a sample of 3,919 manufacturing and services firms taken from the Spanish Technological Innovation Panel (PITEC) for the period 2008â€“2012. Firstly, applying a principal component analysis we identified a diverse range of innovation strategies (no strategy, unfocused, market, production, cost and environmental and regulatory strategy). Secondly, after controlling positive skewness of the dependent variables a generalized linear model is used to exanimate the impact of these innovation strategies. Our empirical results reveal some relevant aspects. Firstly, firms that do not have a well-defined innovation strategy experience fewer probability of being a successful innovative firm. Secondly, firms that do have an innovation strategy, but not focused on any specific orientation, have enhanced innovation success, but less than that of firms with an oriented strategy. Finally, the results also show that there is a good fit between an oriented strategy pursued by firms and their innovation success.

Rotating Scroll Vacuum Pump

Rotating vacuum pumps used 1n various f1elds have been required to have high performance, compactness, low noise/vlbration. Although, a sl1d1ng vane type has been popular as a rotary vacuum pump, the authors paid attention to the possibllity of a scroll vacuum pump satisfy1ng these requirements. Scroll machines have very good character1st1cs, i.e. low noise/vibration, mechan~c01l s1mplificat1on, fewer parts as compared w1th sliding vane type machines. The authors have attemped to develop a scroll vacuum pump. A rotating mechanism was employed 1nstead of an orb1ting mechanism from the point of v1ew of load pattern and very good sealing characteristics. Adopt1ng the rotating mechanism, the radial seal1ng mechan1sm is particularly easy and effective due to the stationary seal line. A spiral w1th zero top clearance volume and a compact Oldham coupl1ng were adopted. An ultimate v01cuum pressure of 1x1o4 Torr for oil flooded operat1on was achieved at 1AOO rpm. This paper describes the authors design philosophy concerning the scroll shape, Oldham coupling, and oil sealing mechanism. Also, the experimental results are presented. INTRODUCTION Vacuum pumps have been used in varlous fields, sem1-conductor device, new advanced mater1als, nuclear fusion, etc. Recently, due to the extensive applicat1ons in these f1elos, vacuum pumps have been required to meet var1ous demands. An 01l-sealed rotary vacuum pump is a most typical one used in the pressure range above medium vacuum, and high performance, compact s1ze, easy maintenance, low noise, and low vibration are required of lt. Whereas sl1ding vane rotary vacuum pumps are widely used today, the authors have attempted to develop a scroll vacuum pump to respond to the above demands. The scroll machines have two types. One is an orbi.t1ng type w1th one scroll f1xed and the other orbiting aga1nst it. The other type is a rotat1ng type Wl th two scrolls rotat1ng i.n the same direction as each other. An orb1t~ng type has already been developed as a refrigeration compressor in a1r condltloning equipment. Only one orbit~ng type is seen as the vacuum pump 1n reference(1),(? ), the rotat1ng type scroll vacuum pump wh1ch has been descr1bed here 1s the world's f1rst. The scroll machines have such attract~ve features as : good sealing characteristics, low v1brat1on and no~se, mechanical simpllcity, fewer p01rts, and so on. And the seal1ng technique 1n the rotat1ng scroll type is easler than in the orb~t1ng type.
OTP system with third party trusted authority as a mediator

One Time Password is one of the preferable security techniques to do online transaction. If the security level is compared, it shows the need of improvement in its transaction methods and medium. In this paper, two authorities are considered viz. bank domain itself and third party as a trusted authority. Third party authority will have its own secrete key based on its own considered attributes. This key will be combined with user attribute key to form encrypted key. This key will be stored in temp database till session time is available. Here the two new concepts are added as to use third party secrete key and storing this key into temp database for predefined session time only. After these stages only main database can be accessed. It will increase the security level to make secure online transaction.

The present review focuses on the benzothiazoles with potential activities that are now in development.
Special issue on Decision Support Systems for Medical Applications

Applications such as medical imaging depend strongly on the computer aided decision support systems for disease diagnosis and treatment planning. This applies an extra pressure on the computer based systems to provide highly accurate results within less convergence time. Soft computing techniques are widely preferred for such applications because of its numerous advantages. Though theoretically proven, these methodologies are rarely used in practice in real time scenario. This is mainly due to the various existing gaps between the theoretical and practical cases of soft computing approaches. This special issue stands as a bridge to unify the theoretical and practical concepts of soft computing techniques in the context of medical imaging applications. The focus of the special issue is on throwing new seeds of soft computing techniques for feasible application in the medical field.
An Investigation into the Expectations of the Recruiters and the Preparedness of the Management Graduates for Effective On-Job Performance

The key distinguishing factor which makes a professional course unique and distinct from any other stream of education is the focus on the application of the program in real life which is simply understood as employment. Recruiters and academic institutions attempt to work in tandem such that the product (fresh graduates from the program) is prepared and ready to get on board. This paper explores recruiters’ expectations vis-a-vis fresh management graduates with a specific emphasis on self-awareness quotient of fresh recruits and its impact on the performance of the students on job. It further brings forth the self-awareness levels of the final year management graduates on the set of skills considered essential for effective on-job performance of fresh management recruits across a range of sectors—manufacturing to services.
Limited Utility of Magnetic Resonance Imaging in Determining the Primary Site of Disease in Patients With Inconclusive Endometrial Biopsy

Objective: To evaluate the utility of preoperative magnetic resonance imaging (MRI) in determining whether primary disease site is cervical or endometrial in patients with inconclusive preoperative endometrial biopsy. Methods: We retrospectively identified all patients who underwent pelvic MRI and who had a preoperative diagnosis of cervical or endometrial cancer at MD Anderson Cancer Center between 1990 and 2006. The subset in which endometrial biopsy did not clarify the primary disease site was analyzed. Magnetic resonance imaging results were compared with postoperative histopathologic findings. Results: A total of 168 patients who underwent MRI who had a preoperative diagnosis of cervical or endometrial cancer were identified. Of these patients, 51 had an inconclusive endometrial biopsy. Magnetic resonance imaging suggested an endometrial primary tumor without cervical invasion in 28 patients, of whom 21 (75%) actually had such a tumor and 7 had an endometrial primary tumor with cervical invasion. Magnetic resonance imaging suggested an endometrial primary tumor with cervical invasion in 3 patients, all of whom had such a tumor. Magnetic resonance imaging suggested a cervical primary tumor in 6 patients, of whom 5 had such a tumor and 1 had an endometrial primary tumor without cervical invasion. Magnetic resonance imaging was inconclusive (did not clarify primary disease site or no lesion visualized) in 14 (27%) of 51 patients, 6 of whom had an endocervical primary tumor or an endometrial tumor with cervical involvement. Overall, preoperative MRI was either inaccurate or unhelpful in 22 (43%) of 51 patients. Conclusion: Preoperative MRI in patients with inconclusive endometrial biopsy is inaccurate or unhelpful in nearly half of patients.
Association between commercial and traditional sugar-sweetened beverages and measures of adiposity in Costa Rica

Abstract Objective Increasing trends in the consumption of commercial sugar-sweetened beverages (SSB) have occurred in parallel with rising levels of obesity in Latin America, but data showing the relationship between these SSB and obesity are limited. The current study examined the association between commercial and traditional SSB and measures of adiposity in Costa Rica. Design A cross-sectional analysis was conducted in which the exposure, SSB intake, was defined as frequency of daily servings of ‘fresco’ (a traditional home-made beverage), fruit drink (commercially available SSB), soda and fruit juice (made from fruits at home). Multivariate linear regression was used to estimate associations between SSB intake and BMI, waist-to-hip ratio and skinfold thickness. Setting Central Valley, Costa Rica. Subjects Controls (n 2045) of a case–control study on diet and heart disease in Costa Rica. Results Fresco, fruit drink, soda and fruit juice were consumed ≥1 time/d by 47 %, 14 %, 4 % and 14 % of the population, respectively. One serving/d of soda, fruit drink and fresco was associated with 0·89, 0·49 and 0·21 kg/m2 higher BMI, respectively (all P < 0·05). Fruit drink (≥1 serving/d) was associated with higher waist-to-hip ratio (P = 0·004), while soda and fresco were associated with higher skinfold thickness (P = 0·02 and 0·01, respectively). Associations with fruit juice intake were modest and not statistically significant. Other factors associated with higher BMI were higher income and less education, smoking and physical inactivity (all P < 0·05). Conclusions Increasing intake of commercially available SSB could be in part responsible for the high prevalence of obesity among Hispanic adults.
Universal test complexity of field-programmable gate arrays

A field-programmable gate array (FPGA) can implement arbitrary logic circuits in the field. In this paper we consider universal test such that when applied to an unprogrammed FPGA, it ensures that all the corresponding programmed logic circuits on the FPGA are fault-free. We focus on testing for look-up tables in FPGAs, and present two types of programming schemes; sequential loading and random access loading. Then we show test procedures for the FPGAs with these programming schemes and their test complexities. In order to make the test complexity for FPGAs independent of the array size of the FPGAs, we propose a programming scheme called block-sliced loading, which makes FPGAs C-testable.
The Relationship Between Product Placement And the Performance of Movies

ABSTRACT Star power, genre, sequel, and word of mouth (WOM), are among the critical factors affecting a film's box-office success. The current study added a new wrinkle to the WOM factor, analyzing whether advertising in the form of product placements in films affected consumer enjoyment of the movie, and, in turn, whether the related positive or negative WOM about the film affected box-office revenues. The authors investigated the relationship between product placements and the performance of 122 movies released between 2000 and 2007 and found that product placements had both helpful and harmful consequences. Product placements exhibited a positive relationship with movie revenues, but when used in excess (i.e., more than 44 placements per movie) the relationship with revenues turned negative.
To GEE or Not to GEE: Comparing Population Average and Mixed Models for Estimating the Associations Between Neighborhood Risk Factors and Health

Two modeling approaches are commonly used to estimate the associations between neighborhood characteristics and individual-level health outcomes in multilevel studies (subjects within neighborhoods). Random effects models (or mixed models) use maximum likelihood estimation. Population average models typically use a generalized estimating equation (GEE) approach. These methods are used in place of basic regression approaches because the health of residents in the same neighborhood may be correlated, thus violating independence assumptions made by traditional regression procedures. This violation is particularly relevant to estimates of the variability of estimates. Though the literature appears to favor the mixed-model approach, little theoretical guidance has been offered to justify this choice. In this paper, we review the assumptions behind the estimates and inference provided by these 2 approaches. We propose a perspective that treats regression models for what they are in most circumstances: reasonable approximations of some true underlying relationship. We argue in general that mixed models involve unverifiable assumptions on the data-generating distribution, which lead to potentially misleading estimates and biased inference. We conclude that the estimation-equation approach of population average models provides a more useful approximation of the truth.
Investors' Payout-form Preference and Taxes

We find regularly cash-dividend-paying firms in the U.S. have a price premium compared to regularly stockrepurchasing firms in the early 1970s, but this premium turns into a discount by the mid-to-late 2000s. The premium (discount) is related to the differential tax burden on dividends and capital gains. It is not related to the excess market return. This evidence supports the investor-rationality assumption underlying Miller and Modigliani’s (1961) theory and shows that the marginal investor is not tax-exempt as Miller and Scholes (1978) propose. Managers’ subordination of investors’ taxes indicated in the surveys of Brav et al. (2005, 2008) is sub-optimal. JEL classification: G35; G11
Performance Evaluation and Analysis of Vanishing Point Detection Techniques

Vanishing point detection algorithms based on a Gaussian sphere representation have been employed in a variety of computer vision systems, for extracting 3D line orientations as a first step towards object detection. Typically, these algorithms have been applied to imagery with strong perspective effects and with little noise or texture, resulting in good solutions for line orientations. However, these algorithms can fail if perspective effects are weak, or if texture edges are predominant; they also fail to take advantage of knowledge about the objects to be detected. In this paper, two new techniques for robust vanishing point detection on the Gaussian sphere are presented; primitive-based vanishing point analysis and interpretation plane error modeling. The performance of these methods, along with two other existing methods from the literature, are quantitatively evaluated and compared for the task of building detection in complex aerial imagery.
Influence of Age on Antibody Response and Persistence Following Immunization With MenAfriVac

Background. A meningococcal group A conjugate vaccine, PsA-TT (MenAfriVac), developed through the Meningitis Vaccine Project and manufactured by the Serum Institute of India, Ltd, was tested in multiple clinical trials conducted mainly in Africa. The impact of age at which subjects were vaccinated on immune response and persistence postimmunization with PsA-TT was the main focus of the current analysis. Methods. Subjects who were vaccinated with a single dose of 10 µg of PsA-TT at 12–23 months or 22–33 months of age in study A conducted in Mali and The Gambia; at 2–10 years, 11–17 years, or 18–29 years of age in study B conducted in Mali, The Gambia, and Senegal; and at 14–18 weeks, 9–12 months, or 12–18 months of age in study C conducted in Ghana are included in the current analysis. Immunogenicity was measured by group A serum bactericidal antibody (SBA) titer with baby rabbit complement. Results. Significant differences in SBA titers were found among the age groups in studies B and C both 28 days and 1 year postimmunization. A significant difference in SBA titers between age groups 12–23 months and 22–33 months was only observed 1 year postimmunization in study A. Antibody titers remained at similar levels from 1 to 2 years postimmunization for subjects vaccinated at 12–23 months in study A and at 9–12 months or 12–18 months of age in study C. Conclusions. Subjects immunized at different ages had different postimmunization immune responses as measured by SBA titers. Toddlers tended to have higher immune responses than infants. This pattern persisted at least 1 year postimmunization. Clinical Trials Registration. ISRCTN78147026 (study A), ISRCTN87739946 (study B), and ISRCTN82484612 (study C).
Design, Synthesis, Biological Evaluation, and Docking Study of Acetylcholinesterase Inhibitors: New Acridone‐1,2,4‐oxadiazole‐1,2,3‐triazole Hybrids

In this study, novel acridone‐1,2,4‐oxadiazole‐1,2,3‐triazole hybrids were designed, synthesized, and evaluated for their acetylcholinesterase and butyrylcholinesterase inhibitory activity. Among various synthesized compounds, 10‐((1‐((3‐(4‐methoxyphenyl)‐1,2,4‐oxadiazol‐5‐yl)methyl)‐1H‐1,2,3‐triazol‐4‐yl)methyl)acridin‐9(10H)‐one 10b showed the most potent anti‐acetylcholinesterase activity (IC50 = 11.55 μm) being as potent as rivastigmine. Also docking outcomes were in good agreement with in vitro results confirming the dual binding inhibitory activity of compound 10b.
A non-linear model for micropower rectifiers in UHF-band RFIDs

This paper proposes a non-linear transient model for voltage-doubler circuits. By using a novel approach to model the waveform of intermediate voltages, both the dc output voltage and power spectrum are derived. Substrate currents are included to enable accurate modelling of high power applications. The model is validated by both low and high power rectifiers in UMC CMOS 0. 18µm technology. The proposed model is in good agreement with simulations in both time and frequency domains.
Frame-based Data Factorizations

Archetypal Analysis is the method of choice to compute interpretable matrix factorizations. Every data point is represented as a convex combination of factors, i.e., points on the boundary of the convex hull of the data. This renders computation inefficient. In this paper, we show that the set of vertices of a convex hull, the so-called frame, can be efficiently computed by a quadratic program. We provide theoretical and empirical results for our proposed approach and make use of the frame to accelerate Archetypal Analysis. The novel method yields similar reconstruction errors as baseline competitors but is much faster to compute.
Flame atomic absorption spectrometric determination of Pb(II) and Cd(II) in natural samples after column graphene oxide-based solid phase extraction using 4-Acetamidothiophenol

The determination of lead and cadmium by flame atomic absorption spectrometry after solid phase extraction on graphene oxide column with use of 4-acetamidothiophenol (ATP) as chelating reagent was described. PM6 semi-empirical and PBE density functional theory methods were used to investigation of adsorption mechanism of the complexes on GO sheet. The main factors influencing the preconcentration and determination of the analytes (pH, ATP amount, eluent type and concentration, flow rate and sample volume) were examined in detail. The effect of interfering ions on the separation-preconcentration of analytes was also investigated. For Pb(II) and Cd(II) solutions of 1.0 µg L-1, the preconcentration factor was as high as 250 (under the optimized conditions). The detection limits for Pb(II) and Cd(II) were 170 and 80 ng L-1, respectively. The validity of the proposed method was checked with standard reference materials and it has been successfully applied for the determination of trace Pb(II) and Cd(II) in water, herbal and fish samples with the recoveries of 99.4-103.5%.
Visual Acuity and Stimulus‐Seeking Behavior

&NA; The classic concept of a sense organ as a passive receiver of stimulation is evolving toward a view that considers its exploratory capabilities and its implications for orientation and arousal. Recent research, for example, suggests that the pupillary response and fixation saccadic eye movements are directly implicated in processes of cortical activation. Results of this study suggest that visual acuity may also be better understood within an activation theory framework. Specifically, the position was taken that individuals with low visual acuity might be seen as persons with low preferred levels of activation who seek to reduce stimulus input to maintain activation at their preferred level. In support of this position, individuals with high uncorrected visual acuity were found to demonstrate a higher preferred level of stimulation and to produce more exciting and novel stories in response to TAT stimuli than did low‐acuity individuals.
Chest radiograph appearances 63 years after ‘plombage’ performed for cavitating tuberculosis

An 82-year-old woman had a recent routine chest radiograph when she presented with a tachycardia. This demonstrated the result of a surgical procedure performed for pulmonary tuberculosis in 1947. Examination revealed a large, left sided, vertical dorsal thoracotomy scar. In the late 1940s, single agent chemotherapy with streptomycin could not guarantee a cure …
