Career decision making, stability and actualization of career intentions: The case of entrepreneurial intentions

Career counselors are often concerned with stability and likelihood of implementation of clients’ career intentions. It is often assumed that the status in career decision making (CDM) is one likely indicator, yet empirical support for this assumption is sparse. The present study focused on entrepreneurial career intentions (EI) and showed that German university students (N = 1,221), with high EI can be found in very different empirically derived CDM statuses that range from pre-concern to mature decidedness. Longitudinal analyses (n = 561) showed that career choice foreclosure (high decidedness/low exploration) related to more EI stability and that mature decidedness (high decidedness/high exploration) amplified effects of EI on opportunity identification, a form of EI actualization. The results imply that CDM statuses are useful to estimate stability and actualization of career intentions.

The influence of the valence of events on the intention superiority effect over the life-course

According to the intention superiority effect, people remember more future intentions than past events. Moreover, several studies have shown a facilitation of retrieving positive compared to negative or neutral events. The aim of the present study was to investigate the influence of age on the intention superiority effect for positive, negative and neutral events. We asked a group of young and a group of older adults to report their future intentions and their memories of past events from a specific time-window (i.e., day, week or year). Additionally, we prompted them to rate each intention/memory as positive, negative or neutral. The results showed more positive than negative or neutral future and past events in both age-groups and more negative events of young adults compared with reported negative events of older adults. Critically, there was an intention superiority effect for positive events in both age-groups, but only in the “year” time-window. These results suggest that the retrieval of positive future events is facilitated, at least for a large time-perspective, and independent of age-effects.

Sharp neck injuries in suicidal intention

Sharp neck injuries in suicidal intention often present as serious emergency situations with the need for an immediate diagnosis and treatment. We report our study of the clinical evolution of this emergency condition. This study investigates the cases of sharp neck injuries in suicidal intention treated at our institution between 2000 and 2010. Patient records were collected in a retrospectively reviewed and analyzed database. The current literature was compared to our findings. We found 36 cases (10 female and 26 male). The neck injuries were superficial and profound in 16 and 20 patients, respectively. Twenty-two patients were seen by the Head and Neck surgeon. A surgical neck exploration was necessary in 19 cases. Tracheal, laryngeal, pharyngeal and vascular injuries were found in one, five, three and three cases, respectively. The hospital stay ranged from 1 to 47 days. All the patients underwent emergency psychiatric assessment and were subsequently referred for psychiatric treatment. One patient died in the emergency room from an additional arterial injury to the wrist. Sharp neck injuries in suicidal intention treated with an interdisciplinary medical, surgical and psychiatric emergency assessment and treatment have low mortality and morbidity.

Explaining car drivers' intention to prevent road-traffic noise: An application of the Norm Activation Model

Strengthening car drivers’ intention to prevent road-traffic noise is a first step toward noise abatement through voluntary change of behavior. We analyzed predictors of this intention based on the norm activation model (i.e., personal norm, problem awareness, awareness of consequences, social norm, and value orientations). Moreover, we studied the effects of noise exposure, noise sensitivity, and noise annoyance on problem awareness. Data came from 1,002 car drivers who participated in a two-wave longitudinal survey over 4 months. Personal norm had a large prospective effect on intention, even when the previous level of intention was controlled for, and mediated the effect of all other variables on intention. Almost 60% of variance in personal norm was explained by problem awareness, social norm, and biospheric value orientation. The effects of noise sensitivity and noise exposure on problem awareness were small and mediated by noise annoyance. We propose four communication strategies for strengthening the intention to prevent road-traffic noise in car drivers.

Solitaire™ with the Intention for Thrombectomy as Primary Endovascular Treatment for Acute Ischemic Stroke (SWIFT PRIME) trial: protocol for a randomized, controlled, multicenter study comparing the Solitaire revascularization device with IV tPA with IV tPA alone in acute ischemic stroke.

RATIONALE Early reperfusion in patients experiencing acute ischemic stroke is critical, especially for patients with large vessel occlusion who have poor prognosis without revascularization. Solitaire™ stent retriever devices have been shown to immediately restore vascular perfusion safely, rapidly, and effectively in acute ischemic stroke patients with large vessel occlusions. AIM The aim of the study was to demonstrate that, among patients with large vessel, anterior circulation occlusion who have received intravenous tissue plasminogen activator, treatment with Solitaire revascularization devices reduces degree of disability 3 months post stroke. DESIGN The study is a global multicenter, two-arm, prospective, randomized, open, blinded end-point trial comparing functional outcomes in acute ischemic stroke patients who are treated with either intravenous tissue plasminogen activator alone or intravenous tissue plasminogen activator in combination with the Solitaire device. Up to 833 patients will be enrolled. PROCEDURES Patients who have received intravenous tissue plasminogen activator are randomized to either continue with intravenous tissue plasminogen activator alone or additionally proceed to neurothrombectomy using the Solitaire device within six-hours of symptom onset. STUDY OUTCOMES The primary end-point is 90-day global disability, assessed with the modified Rankin Scale (mRS). Secondary outcomes include mortality at 90 days, functional independence (mRS ≤ 2) at 90 days, change in National Institutes of Health Stroke Scale at 27 h, reperfusion at 27 h, and thrombolysis in cerebral infarction 2b/3 flow at the end of the procedure. ANALYSIS Statistical analysis will be conducted using simultaneous success criteria on the overall distribution of modified Rankin Scale (Rankin shift) and proportions of subjects achieving functional independence (mRS 0-2).

A longitudinal cross-country study of entrepreneurial orientation

As recent research documents, there has been an impressive effort of studying the entrepreneurial orientation construct and its nomological role. However, most research has been very context specific and based on the analyses of cross-sectional information. We study causal performance effects from entrepreneurial orientation and its key dimensions in two economic contexts–developed and emerging markets. Gathering data on a sample of 94 firms in developed market context and 108 in emerging market context at two time-points we explore our hypotheses. The results suggest that in a developed economy entrepreneurial orientation has a positive impact on firm performance, whereas in the emerging market context this effect is negative. Furthermore, we assess the contribution of each dimension to the aggregate construct and reveal the importance of risk-taking in both contexts. Finally, we highlight the role of environmental dynamism and explain its varying effect

Firm-level strategic orientation and performance: a synthesis and extension of the knowledge base on entrepreneurial, market and learning orientation

Should a firm stay focused or should it rather adopt a broader strategic perspective? This dissertation summarizes and extends the existing knowledge base on entrepreneurial, market, and learning orientation. Building on multiple theoretical perspectives, empirical evidence from prior studies, as well as on survey and archival data collected in two economic contexts, performance effects from individual orientations, their dimensions and combinations are explored. Results reveal that the three strategic orientations are highly interrelated and that their relationship to firm performance is more complex than previously assumed.

The Entrepreneurial Theory of the Firm and the Theory of the Entrepreneurial Firm

The entrepreneurial theory of the firm argues that entrepreneurship, properly understood, is a crucial but neglected element in explaining the nature and boundaries of the firm. By contrast, the theory of the entrepreneurial firm presumably seeks not to understand the nature and boundaries of "the firm" in general but rather to understand a particular type of firm: one that is entrepreneurial. This paper is an attempt to reconcile the two. After briefly delving for the concept of entrepreneurship in the work of Schumpeter, Kirzner, and (especially) Knight, the paper makes the case for the entrepreneurial theory of the firm. In such a theory, the firm exists as the solution to a coordination problem in a world of change and uncertainty, including Knightian or structural uncertainty. Taking a historical or developmental perspective, the paper then examines the changing nature of the entrepreneurial coordination problem over the life-cycle. In this formulation, "the entrepreneurial firm" is a nascent firm or proto-firm facing a problem of coordinating systemic change in economic capabilities. Lacking (by definition) adequate guidance from existing systems of rules of conduct embedded in markets or organizations, the entrepreneurial firm typically relies on a form of organization Max Weber called charismatic authority. In the end, although there is no such thing as a non-entrepreneurial firm, firms that must solve coordination problems in a world of novelty and systemic change ("entrepreneurial firms") are perhaps the purest case of the entrepreneurial theory of the firm.

Evaluation of the causal pathways through which subjective norms influence mammography intention and stage of change in a national sample of women veterans

Few studies have investigated causal pathways linking psychosocial factors to each other and to screening mammography. Conflicting hypotheses exist in the theoretic literature regarding the role and importance of subjective norms, a person's perceived social pressure to perform the behavior and his/her motivation to comply. The Theory of Reasoned Action (TRA) hypothesizes that subjective norms directly affect intention; while the Transtheoretical Model (TTM) hypothesizes that attitudes mediate the influence of subjective norms on stage of change. No one has examined which hypothesis best predicts the effect of subjective norms on mammography intention and stage of change. Two statistical methods are available for testing mediation, sequential regression analysis (SRA) and latent variable structural equation modeling (LVSEM); however, software to apply LVSEM to dichotomous variables like intention has only recently become available. No one has compared the methods to determine whether or not they yield similar results for dichotomous variables. ^ Study objectives were to: (1) determine whether the effect of subjective norms on mammography intention and stage of change are mediated by pros and cons; and (2) compare mediation results from the SRA and LVSEM approaches when the outcome is dichotomous. We conducted a secondary analysis of data from a national sample of women veterans enrolled in Project H.O.M.E. (H&barbelow;ealthy O&barbelow;utlook on the M&barbelow;ammography E&barbelow;xperience), a behavioral intervention trial. ^ Results showed that the TTM model described the causal pathways better than the TRA one; however, we found support for only one of the TTM causal mechanisms. Cons was the sole mediator. The mediated effect of subjective norms on intention and stage of change by cons was very small. These findings suggest that interventionists focus their efforts on reducing negative attitudes toward mammography when resources are limited. ^ Both the SRA and LVSEM methods provided evidence for complete mediation, and the direction, magnitude, and standard errors of the parameter estimates were very similar. Because SRA parameter estimates were not biased toward the null, we can probably assume negligible measurement error in the independent and mediator variables. Simulation studies are needed to further our understanding of how these two methods perform under different data conditions. ^

Health beliefs and attitudes of HPV among Hispanic parents as predictors of intention to use the HPV vaccine

Human Papillomavirus (HPV) is the most common sexually transmitted disease in the United States. Although HPV prevalence is high in the United States, there are a limited number of research studies that focus on Hispanics, who have higher incidence rates of cervical cancer than their non-Hispanic counterparts. The HPV vaccine introduced in 2006 may offer a feasible solution to the issues surrounding high prevalence of HPV. Due to the high prevalence of HPV infection among adolescents and young adults it has been suggested that HPV vaccination begin prior to onset sexual activity and focus on non-sexually active adolescents and pre-adolescents. Consequently, it has become increasingly important to assess knowledge and awareness of HPV in order to develop effective intervention strategies. This pilot study evaluated the knowledge and health beliefs of Hispanic parents regarding HPV and the HPV vaccine using a newly developed questionnaire based on the constructs of the Health Belief Model. The sample was recruited from an ob-gyn office in El Paso, Texas. Descriptive data show that the majority of the sample was female (94.1%), Hispanic (76.5%), Catholic (64.7%), and had at least a high school education (55.9%). Chi-square analysis revealed that the following variables differed amongst parents who intended to vaccinate their child against HPV and those who did not: religion (p=0.038), perceived severity item "HPV infections are easily treated" (p=0.052), perceived benefits item "It is better to vaccinate a child against an STI before they become sexually active" (p=0.014) and perceived barriers item "The HPV vaccine may have serious side effects that could harm my child" (p=0.004). Univariate logistic regression indicated that religion (OR = 4.8, CI: 1.04, 21.8) and "The HPV vaccine may have serious side effects that could harm my child" (OR = 15.9, CI: 1.73, 145.8) were significant predictors of parental intention to vaccinate. Multivariate logistic regression, using backwards elimination, indicated that religion (OR = 7.7, CI: 1.25, 47.8) and "The HPV vaccine may have serious side effects that may harm my child" (OR = 7.6, CI: 1.15, 50.2) were the best predictive variables for parental intention to vaccinate. ^

Pregnancy intention, intimate partner violence, and the use of prenatal care in Jordan

Previous research has suggested an association between intimate partner violence and pregnancy intention status, and pregnancy intention status and the use of prenatal care services, however much of these studies have been conducted in high income countries (HIC) rather than low and middle income countries (LMIC). The objectives of this study were to examine the relationship between pregnancy intention status and intimate partner violence, and pregnancy intention status and the use of prenatal care among ever-married women in Jordan.^ Data were collected from a nationally representative sample of women interviewed in the 2007 Jordan Demographic and Health Survey. The sample was restricted to ever-married women, 15–49 years of age, who had a live birth within the five years preceding the survey. Multivariate logistic regression analyses was used to determine the relationship between intimate partner violence and pregnancy intention status, and pregnancy intention status and the use of prenatal care services.^ Women who reported a mistimed pregnancy (PORadj 1.96, 95% CI: 1.31–2.95), as well as an unwanted pregnancy (PORadj 1.32, 95% CI: 0.80–2.18) had a higher odds of experiencing lifetime physical and/or sexual abuse compared with women reporting a wanted pregnancy. Women not initiating prenatal care by the end of the first trimester had statistically significant higher odds of reporting both a mistimed (PORadj 2.07, 95% CI: 1.55–2.77) and unwanted pregnancy (PORadj 2.36, 95% CI: 1.68–3.31), compared with women initiating care in the first trimester. Additionally, women not receiving the adequate number of prenatal care visits for their last pregnancy had a higher odds of reporting an unwanted pregnancy (PORadj 2.11, 95% CI: 1.35–3.29) and mistimed pregnancy (POR adj 1.41, 95% CI: 0.96–2.07).^ Reducing intimate partner violence may decrease the prevalence of mistimed or unwanted pregnancies, and reducing both unwanted and mistimed pregnancies may decrease the prevalence of women not receiving timely and adequate prenatal care among women in this population. Further research, particularly in LMIC, is needed regarding the determinants of unintended pregnancy and its association with intimate partner violence as well as with the use of prenatal care services. ^

Value, quality, purchasing habits and repurchase intention in B2C: differences between frequent and occasional purchasers

Este estudio propone un modelo integrador de la recompra en comercio electrónico (B2C), basado en la teoría de la confirmación de expectativas, tomando como partida el modelo de Bhattacherjee extendido con el modelo de satisfacción Cronin. El modelo de investigación se ha probado con 536 compradores españoles, usando análisis multigrupo. El modelo fue capaz de explicar más del setenta por ciento de la varianza de la intención de recompra. Como resultados, la relación entre la calidad y la satisfacción es no significativa para todos los tipos de consumidores y la relación entre la utilidad y la recompra es no significativa sólo para los compradores más frecuentes. Algunas ideas para llevar a la práctica son presentadas a modo de discusión.
