Linking Entrepreneurial Orientation and Firm Performance: The Role of Organizational Learning Capability and Innovation Performance
2013
This research contributes to the entrepreneurial orientation (EO)–performance literature by offering a wider picture that includes two intermediate steps: organizational learning capability (OLC) and innovation performance. This study also provides an explanation of intra-industry firm performance differences by focusing on EO. We use structural equation modeling to test the hypotheses on a data set from Italian and Spanish ceramic tile producers. The results support our conceptual model and demonstrate its usefulness in explaining differences in intra-industry firm performance. Findings suggest that OLC and innovation performance should be enhanced by managers in order to boost the positiv…
Implementation Activities and Organizational Sensemaking
2008
Corporate change initiatives trigger a series of activities aimed at implementing change. It is often assumed that successful implementation requires consistent action based on a shared understanding of the changes among employees. This article examines how implementation activities affect individual and organizational sensemaking processes and thereby contribute to a shared understanding and consistent change action. Based on inductive analyses of longitudinal data, the study suggests that many implementation activities focus predominantly on further planning and creating a cognitive understanding among change recipients prior to any action. Although participation in planning activities f…
Towards a network-based view of effective entrepreneurial ecosystems
2021
AbstractWe conceptualize entrepreneurial ecosystems as fundamentally reliant on networks and explore how and under what conditions inter-organizational networks lead an entrepreneurial ecosystem to form and evolve. It is widely accepted that entrepreneurial ecosystems possess a variety of symbiotic relationships. Research has focused considerable efforts in refining the structure and content of resources found within these networked relationships. However, merely focusing on actor-level characterizations dilutes the notion that social relationships change and are complex. There has been little conceptual treatment of the behavioral and governance factors that underpin how quality interactio…
Extending the international new venture phenomenon to digital platform providers : A longitudinal case study
2018
People increasingly interact with services enabled by digital platforms. This has been a consequence of the digitalization of artifacts, which has transmuted traditional businesses into digital forms. With the increasing digitalization and modularization of services, digital platforms have given many digital service providers possibilities to scale globally, and to rapidly transcend national borders by serving multi-sided markets. However, we still know very little about how digital platform providers actually internationalize their services, or how they make their platforms available for global markets. In this paper, we contribute to the increasing literature on digital-based INVs, examin…
Qualitative Longitudinal Research in Health Research: A Method Study
2022
Abstract Background Qualitative longitudinal research (QLR) comprises qualitative studies, with repeated data collection, that focus on the temporality (e.g., time and change) of a phenomenon. The use of QLR is increasing in health research since many topics within health involve change (e.g., progressive illness, rehabilitation). A method study can provide an insightful understanding of the use, trends and variations within this approach. The aim of this study was to map how QLR articles within the existing health research literature are designed to capture aspects of time and/or change. Methods This method study used an adapted scoping review design. Articles were eligible if they were wr…
Personality and Labour Market Income: Evidence from Longitudinal Data
2010
This study contributes to the literature on how personality is rewarded in the labour market by examining the relationship between personality and labour market income. Our results suggest that adulthood extraversion is positively associated with income when education, work experience, and unemployment history, measured prospectively from longitudinal data, are controlled for. In addition, childhood constructiveness indicating active and well-controlled behaviour has a positive association with income in adulthood.
Children and partners of patients with recurrent respiratory papillomatosis have no evidence of the disease during long-term observation.
2006
Summary Objective Recurrent respiratory papillomatosis (RRP) is the most common benign neoplasm affecting the larynx and upper respiratory tract. The aim of our study was to investigate whether children and partners of patients with RRP develop the same disease and to determine whether there is an impact of pregnancy on the course of RRP. Patients and methods Thirty-eight of 42 patients with RRP were accepted for a multicenter prospective study in Germany in 21.06.83–12.03.90. Mean follow-up duration was 15.3 ± 1.8 years. The data of partners of patients with RRP was collected during the period of observation and then updated via interviews in January 2006. Twenty-nine children and four gra…
[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].
2008
Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…
Simultaneous laser generation and laser ultrasonic detection of the mechanical breakdown of a coating–substrate interface
2001
Abstract The present study deals with information that could be obtained by real-time contactless monitoring of the normal displacement, due to the propagation of the longitudinal waves generated by nanosecond pulsed laser irradiation, through a transparent and porous ceramic coating deposited on a metallic substrate. These displacements were recorded in real-time at the rear surface of the specimens using a laser heterodyne interferometer and were correlated with the different steps of laser/material interaction (thermoelastic interactions, fracture of the coating–substrate interface and coating expulsion). An analytical model was developed to establish a relation between the longitudinal …
Survival time and differences between dementia with Lewy bodies and Alzheimer’s disease following diagnosis: a meta-analysis of longitudinal studies.
2019
Objective: To synthesize the evidence across longitudinal studies comparing survival in dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Methods: We conducted a systematic review and meta-analysis of studies comparing survival in clinically diagnosed DLB to AD. Longitudinal cohort studies were identified through a systematic search of major electronic databases from inception to May 2018. A random effects meta-analysis was performed to calculate survival time and relative risk of death. Results: Overall, 11 studies were identified including 22,952 patients with dementia: 2029 with DLB (mean diagnosis age 76.3; 47% female) compared with 20,923 with AD (mean diagnosis age 77.2; 6…
