Entrepreneurial orientation, learning orientation, and innovation in small and medium enterprises

From the resource-based perspective, entrepreneurial orientation and market orientation are two separate but complementary strategic orientations that emphasize the business philosophy and behavior in proactively detecting industrial environment, including market information and competitors strategy, in order to innovate and respond to the customers needs timely. Empirical studies have separately discussed the variables of entrepreneurial orientation and market orientation in relation to firm-level innovation performance. However, there is limited research simultaneously examined the direct effect of entrepreneurial orientation and market orientation on innovation performance, especially individual-level innovation performance. Scholars have suggested that future research may examine strategic human resource practices to explore if organizational factors may enhance or diminish the entrepreneurial orientation on innovation. Both entrepreneurial orientation and market orientation still require organizational learning practices to facilitate higher-order learning and innovation. Although scholars are interested in figuring out if additional moderator variables simultaneously affect market orientation and entrepreneurial orientation on firm performance, limited empirical studies have existed. An organization with high degree of entrepreneurial orientation and market orientation still require learning orientation mechanism to create an environment where mutually beneficial relationships between employees and their organizations to facilitate learning and innovation. Therefore, learning orientation may make an organization innovate effectively. As a result, the overall purpose of this study is to assess the influence learning orientation on relationships between entrepreneurial orientation, market orientation and individual-level job related performance variable, employee innovative behaviors.
Sensors on speaking terms: Schedule-based medium access control protocols for wireless sensor networks

Wireless sensor networks make the previously unobservable, observable. The basic idea behind these networks is straightforward: all wires are cut in traditional sensing systems and the sensors are equipped with batteries and radio’s to virtually restore the cut wires. The resulting sensors can be placed closely to the phenomenon that needs monitoring, without imposing high wiring costs and careful engineering of the position of the devices. Sensors can even be attached to mobile objects. As a result, monitoring can be done more efficiently and at higher sensing resolution compared to traditional sensor systems. Yet, these are not the only advantages of wireless sensor networks. We —as user of the wireless sensor network– are not interested in constant streams of sensor readings, but we are more interested in the interpretation of the sensor readings. This is exactly the big potential of wireless sensor networks. Due to intelligence, added locally to the wireless sensors, and collaboration between the individual sensors, the network by itself can carry out complex tasks related to observing. To achieve these goals, wireless sensors must be ”on speaking terms” i.e. the nodes must be able to exchange information. The aim of this thesis is to provide a set of communication rules —commonly known as medium access control (MAC) protocol– that organizes efficient communication through a shared wireless medium and is well suited for the inherent characteristics of wireless sensor networks. The MAC protocol determines when a wireless sensor transmits its sensor information and is thereby in control of one of the most energy consuming components in the wireless sensor hardware architecture. The lifetime of the battery operated wireless sensors is thus heavily dependant on the efficiency of the MAC protocol. This thesis provides a self-organizing, schedule-based medium access approach. In general, this class of medium access is recognized for its energy-efficiency and robustness against high peak loads. These aspects are required by wireless sensor networks. Its drawbacks are message delay, over-provisioning and required time synchronization between wireless sensors. In our approach, wireless sensors analyse local medium usage and autonomously choose when to access the medium i.e. transmit. In the analysis, medium usage of second order neighbours is also taken into account. Therefore, our approach does not suffer from the well-known hidden terminal problem, and additionally, the wireless medium is spatially reused without energy-wasting conflicts. The medium access schedule of wireless sensors is adjusted when —e.g. due to mobility of nodes– conflicting schedules exist. The correctness of the general medium access control protocol is
Long-term safety and efficacy of fluticasone/formoterol combination therapy in asthma.

BACKGROUND
The long-term safety of a new asthma therapy combining fluticasone propionate and formoterol fumarate (fluticasone/formoterol; flutiform(®)) was assessed.


METHOD
In an open-label study, mild to moderate-severe asthmatics (≥12 years; N=472) were treated twice daily with fluticasone/formoterol 100/10 μg (n=224) or 250/10 μg (n=248) for 6 months (n=256) or 12 months (n=216). The primary and secondary objectives were the long-term safety and efficacy of fluticasone/formoterol, respectively.


RESULTS
In total, 413 (87.5%) patients completed the study (of which 175 participated for 12 months). Adverse events (AEs) were reported by 174 patients (36.9%): 67 (29.9%) in the 100/10 μg group and 107 (43.1%) in the 250/10 μg group. The most common AEs (>2%) were nasopharyngitis, dyspnea, pharyngitis, and headache; the majority were mild to moderate. Only 18 (3.8%) patients reported AEs considered study drug-related. Five patients per group experienced 12 serious AEs; none was study medication-related. Asthma exacerbations were reported by 53 patients (11.2%): 46 mild to moderate and nine severe. Clinical laboratory tests and vital signs showed no abnormal trends or clinically important or dose-response-related changes. The efficacy analyses showed statistically significant improvements at every time point throughout the study period at both doses.


CONCLUSION
Fluticasone/formoterol had a good safety and efficacy profile over the 6- and 12-month study periods.
Media as social partners: the social nature of young children's learning from screen media.

Television has become a nearly ubiquitous feature in children's cultural landscape. A review of the research into young children's learning from television indicates that the likelihood that children will learn from screen media is influenced by their developing social relationships with on-screen characters, as much as by their developing perception of the screen and their symbolic understanding and comprehension of information presented on screen. Considering the circumstances in which children under 6 years learn from screen media can inform teachers, parents, and researchers about the important nature of social interaction in early learning and development. The findings reviewed in this article suggest the social nature of learning, even learning from screen media.
Effectiveness of sports massage for recovery of skeletal muscle from strenuous exercise.

OBJECTIVE
Sport massage, a manual therapy for muscle and soft tissue pain and weakness, is a popular and widely used modality for recovery after intense exercise. Our objective is to determine the effectiveness of sport massage for improving recovery after strenuous exercise.


DATA SOURCES
We searched MEDLINE, EMBASE, and CINAHL using all current and historical names for sport massage. Reference sections of included articles were scanned to identify additional relevant articles.


STUDY SELECTION
Study inclusion criteria required that subjects (1) were humans, (2) performed strenuous exercise, (3) received massage, and (4) were assessed for muscle recovery and performance. Ultimately, 27 studies met inclusion criteria.


DATA EXTRACTION
Eligible studies were reviewed, and data were extracted by the senior author (TMB). The main outcomes extracted were type and timing of massage and outcome measures studied.


DATA SYNTHESIS
Data from 17 case series revealed inconsistent results. Most studies evaluating post-exercise function suggest that massage is not effective, whereas studies that also evaluated the symptoms of DOMS did show some benefit. Data from 10 randomized controlled trials (RCTs) do, however, provide moderate evidence for the efficacy of massage therapy. The search identified no trend between type and timing of massage and any specific outcome measures investigated.


CONCLUSIONS
Case series provide little support for the use of massage to aid muscle recovery or performance after intense exercise. In contrast, RCTs provide moderate data supporting its use to facilitate recovery from repetitive muscular contractions. Further investigation using standardized protocols measuring similar outcome variables is necessary to more conclusively determine the efficacy of sport massage and the optimal strategy for its implementation to enhance recovery following intense exercise.
Qualities of exemplary nurse leaders: perspectives of frontline nurses.

AIM
 This paper reports on a study that looked at the characteristics of exemplary nurse leaders in times of change from the perspective of frontline nurses.


BACKGROUND
 Large-scale changes in the health care system and their associated challenges have highlighted the need for strong leadership at the front line.


METHODS
 In-depth personal interviews with open-ended questions were the primary means of data collection. The study identified and explored six frontline nurses' perceptions of the qualities of nursing leaders through qualitative content analysis. This study was validated by results from the current literature.


RESULTS
 The frontline nurses described several common characteristics of exemplary nurse leaders, including: a passion for nursing; a sense of optimism; the ability to form personal connections with their staff; excellent role modelling and mentorship; and the ability to manage crisis while guided by a set of moral principles. All of these characteristics pervade the current literature regarding frontline nurses' perspectives on nurse leaders.


CONCLUSION
 This study identified characteristics of nurse leaders that allowed them to effectively assist and support frontline nurses in the clinical setting.


IMPLICATIONS FOR NURSING MANAGEMENT
 The findings are of significance to leaders in the health care system and in the nursing profession who are in a position to foster development of leaders to mentor and encourage frontline nurses.
More frequent vaginal orgasm is associated with experiencing greater excitement from deep vaginal stimulation.

INTRODUCTION
Research indicated that: (i) vaginal orgasm (induced by penile-vaginal intercourse [PVI] without concurrent clitoral masturbation) consistency (vaginal orgasm consistency [VOC]; percentage of PVI occasions resulting in vaginal orgasm) is associated with mental attention to vaginal sensations during PVI, preference for a longer penis, and indices of psychological and physiological functioning, and (ii) clitoral, distal vaginal, and deep vaginal/cervical stimulation project via different peripheral nerves to different brain regions.


AIMS
The aim of this study is to examine the association of VOC with: (i) sexual arousability perceived from deep vaginal stimulation (compared with middle and shallow vaginal stimulation and clitoral stimulation), and (ii) whether vaginal stimulation was present during the woman's first masturbation.


METHODS
A sample of 75 Czech women (aged 18-36), provided details of recent VOC, site of genital stimulation during first masturbation, and their recent sexual arousability from the four genital sites.


MAIN OUTCOME MEASURES
The association of VOC with: (i) sexual arousability perceived from the four genital sites and (ii) involvement of vaginal stimulation in first-ever masturbation.


RESULTS
VOC was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites. VOC was also associated with women's first masturbation incorporating (or being exclusively) vaginal stimulation.


CONCLUSIONS
The findings suggest (i) stimulating the vagina during early life masturbation might indicate individual readiness for developing greater vaginal responsiveness, leading to adult greater VOC, and (ii) current sensitivity of deep vaginal and cervical regions is associated with VOC, which might be due to some combination of different neurophysiological projections of the deep regions and their greater responsiveness to penile stimulation.
Early bond strength of two resin cements to Y-TZP ceramic using MPS or MPS/4-META silanes

For cementation of yttrium-stabilized tetragonal zirconium polycrystal (Y-TZP) ceramic frameworks, protocols of surface-conditioning methods and available cements vary, resulting in confusion among clinicians regarding selection and effects of different conditioning methods on cement adhesion. This study evaluated the effect of two silanes (3-trimethoxysilylpropylmethacrylate (MPS) and 3-trimethoxysilylpropylmethacrylate/4-methacryloyloxyethyl trimellitate anhydride methyl methacrylate (MPS/4-META) on the adhesion of two resin-based cements (SuperBond and Panavia F 2.0) to Y-TZP ceramic and compared several protocols with those indicated by the manufacturer of each of these cements. Disks of Y-TZP ceramic (LAVA, 3M ESPE) (n = 60) were divided into six experimental groups (n = 10 per group) and treated as follows: (1) silica coating (SC) + MPS silane + SuperBond; (2) SC + MPS/4-META + silane + SuperBond); (3) SC + MPS silane + Panavia F 2.0); (4) SC + MPS/4-META silane + Panavia F 2.0); (5) no conditioning + MPS/4-META silane + Super-Bond (SuperBond instructions); and (6) 50-μm Al2O3 conditioning + Panavia F 2.0 (Panavia F 2.0 instructions). The specimens were subjected to shear-bond testing after water storage at 37°C for 3 months in the dark. Data were analyzed by analysis of variance and Tukey’s HSD (α = 0.05). After silica coating, the mean bond strength of SuperBond cement was not significantly different between MPS and MPS/4-META silanes (20.2 ± 3.7 and 20.9 ± 1.6 MPa, respectively), but the mean bond strength of Panavia F 2.0 was significantly higher with MPS silane (24.4 ± 5.3 MPa) than with MPS/4-META (12.3 ± 1.4 MPa) (P < 0.001). The SuperBond manufacturer’s instructions alone resulted in significantly higher bond strength (9.7 ± 3.1 MPa) than the Panavia F 2.0 manufacturer’s instruction (0 MPa) (P < 0.001). When silica coating and silanization were used, both SuperBond and Panavia F 2.0 cements demonstrated higher bond strengths they did when the manufacturers’ instructions were followed. With SuperBond, use of MPS or MPS/4-META silane resulted in no significant difference when the ceramic surface was silica coated, but with Panavia F 2.0, use of MPS silane resulted in a significantly higher bond strength than use of MPS/4-META. Use of chairside silica coating and silanization to condition the zirconia surface improved adhesion compared with the manufacturers’ cementation protocols for SuperBond and Panavia F 2.0 resin cements.
ACQUISITION BASED ON OPENCV FOR CLOSE-RANGE PHOTOGRAMMETRY APPLICATIONS

Development of the technology in the area of the cameras, computers and algorithms for 3D the reconstruction of the objects from the images resulted in the increased popularity of the photogrammetry. Algorithms for the 3D model reconstruction are so advanced that almost anyone can make a 3D model of photographed object. The main goal of this paper is to examine the possibility of obtaining 3D data for the purposes of the close-range photogrammetry applications, based on the open source technologies. All steps of obtaining 3D point cloud are covered in this paper. Special attention is given to the camera calibration, for which two-step process of calibration is used. Both, presented algorithm and accuracy of the point cloud are tested by calculating the spatial difference between referent and produced point clouds. During algorithm testing, robustness and swiftness of obtaining 3D data is noted, and certainly usage of this and similar algorithms has a lot of potential in the real-time application. That is the reason why this research can find its application in the architecture, spatial planning, protection of cultural heritage, forensic, mechanical engineering, traffic management, medicine and other sciences. * Corresponding author
Clinical performance of a multivariate index assay for detecting early-stage ovarian cancer.

OBJECTIVE
We sought to analyze the effectiveness of a multivariate index assay (MIA) in identifying early-stage ovarian malignancy compared to clinical assessment, CA 125-II, and modified American Congress of Obstetricians and Gynecologists (ACOG) guidelines among women undergoing surgery for an adnexal mass.


STUDY DESIGN
Patients were recruited in 2 related prospective, multi-institutional trials involving 44 sites. All women had preoperative imaging and biomarker analysis. Preoperative biomarker values, physician assessment of ovarian cancer risk, and modified ACOG guideline risk stratification were correlated with surgical pathology.


RESULTS
A total of 1016 patients were evaluable for MIA, CA 125-II, and clinical assessment. Overall, 86 patients (8.5%) had primary-stage I/II primary ovarian malignancy, with 70.9% having stage I disease and 29.1% having stage II disease. For all early-stage ovarian malignancies, MIA combined with clinical assessment had significantly higher sensitivity (95.3%; 95% confidence interval [CI], 88.6-98.2) compared to clinical assessment alone (68.6%; 95% CI, 58.2-77.4), CA 125-II (62.8%; 95% CI, 52.2-72.3), and modified ACOG guidelines (76.7%; 95% CI, 66.8-84.4) (P < .0001). Among the 515 premenopausal patients, the sensitivity for early-stage ovarian cancer was 89.3% (95% CI, 72.8-96.3) for MIA combined with clinical assessment, 60.7% (95% CI, 42.4-76.4) for clinical assessment alone, 35.7% (95% CI, 20.7-54.2) for CA 125-II, and 78.6% (95% CI, 60.5-89.8) for modified ACOG guidelines. Early-stage ovarian cancer in postmenopausal patients was correctly detected in 98.3% (95% CI, 90.9-99.7) of cases by MIA combined with clinical assessment, compared to 72.4% (95% CI, 59.8-82.2) for clinical assessment alone, 75.9% (95% CI, 63.5-85.0) for CA 125-II, and 75.9% (95% CI, 63.5-85.0) for modified ACOG guidelines.


CONCLUSION
MIA combined with clinical assessment demonstrated higher sensitivity for early-stage ovarian malignancy compared to clinical assessment alone, CA 125-II, and modified ACOG guidelines with consistent performance across menopausal status.
Comparative Performance Study of Conventional and Islamic Banking in Pakistan

The purpose of this empirical study is to analyze and compare the performance of Islamic and conventional banking in Pakistan and to find out which of the banking stream is performing better than other. For this study, sample of 22 conventional banks and 5 Islamic banks were selected. For in-depth understanding and sound comparison, key performance indicators were divided into external and internal bank factors. The external factor analysis includes studying the customer behavior and perception about both Islamic and conventional banking. Internal factor analysis includes measure of differences in performance of Islamic and conventional banks in terms of profitability, liquidity, credit risk and solvency. Nine financial ratios were used to gauge profitability, liquidity and credit risk; and a model known as “Bank-o-meter” is used to gauge solvency. Findings suggest in terms of profitability and liquidity conventional banking leads, while in credit risk management and solvency maintenance Islamic banking dominates. Motivating factors for customers of Islamic banking are the location and Shari’a compliance, while in case of conventional banking it is wide range of products and services.
Mining Minimal Contrast Subgraph Patterns

In this paper, we introduce a new type of contrast pattern, the minimal contrast subgraph. It is able to capture structural differences between any two collections of graphs and can be useful in chemical compound comparison and building graph classification models. However, mining minimal contrast subgraphs is a challenging task, due to the exponentially large search space and graph (sub)isomorphism problems. We present an algorithm which utilises a backtracking tree to first compute the maximal common edge sets and then uses a minimal hypergraph transversal algorithm, to derive the set of minimal contrast subgraphs. An experimental evaluation demonstrates the potential of our technique for finding interesting differences in graph data.
A place-based model for understanding community resilience to natural disasters

There is considerable research interest on the meaning and measurement of resilience from a variety of research perspectives including those from the hazards/disasters and global change communities. The identification of standards and metrics for measuring disaster resilience is one of the challenges faced by local, state, and federal agencies, especially in the United States. This paper provides a new framework, the disaster resilience of place (DROP) model, designed to improve comparative assessments of disaster resilience at the local or community level. A candidate set of variables for implementing the model are also presented as a first step towards its implementation. Purchase Export
VDNet: an infrastructure-less UAV-assisted sparse VANET system with vehicle location prediction

Vehicular Ad Hoc Network (VANET) has been a hot topic in the past few years. Compared with vehicular networks where vehicles are densely distributed, sparse VANET have more realistic significance. The first challenge of a sparse VANET system is that the network suffers from frequent disconnections. The second challenge is to adapt the transmission route to the dynamic mobility pattern of the vehicles. Also, some infrastructural requirements are hard to meet when deploying a VANET widely. Facing these challenges, we devise an infrastructure-less unmanned aerial vehicle (UAV) assisted VANET system called Vehicle-Drone hybrid vehicular ad hoc Network (VDNet), which utilizes UAVs, particularly quadrotor drones, to boost vehicle-to-vehicle data message transmission under instructions conducted by our distributed vehicle location prediction algorithm. VDNet takes the geographic information into consideration. Vehicles in VDNet observe the location information of other vehicles to construct a transmission route and predict the location of a destination vehicle. Some vehicles in VDNet equips an on-board UAV, which can deliver data message directly to destination, relay messages in a multi-hop route, and collect location information while flying above the traffic. The performance evaluation shows that VDNet achieves high efficiency and low end-to-end delay with controlled communication overhead. Copyright © 2016 John Wiley & Sons, Ltd.
A clean wafer-scale chip-release process without dicing based on vapor phase etching

A new method to release MEMS chips from a wafer without dicing is presented. It can be applied whenever SOI wafers are used that are structured from both the device and the handle side using DRIE. This method enables the release of extremely fragile structures without any mechanical impact on the chips. No more dicing residues or debris are created and deposited onto the wafer. The basic idea consists of etching deep surrounding trenches on the device and the handle layer that are displaced by about 20 /spl mu/m and thus create overlapping areas. For release, the buried silicon dioxide between the overlapping areas is etched away using hydrofluoric acid vapor phase etching.
