Exploring the experience of the pioneers of change

The world of work with Western society appears to be undergoing a major change. The literature has described this phenomenon as a change from an industrialbased economy to a knowledge-based economy. This change will represent a complete transformation of the world of work; some suggest that everything we have come to accept and know as normal will change. Our present society seems to be in a period of transition. It is a time with many challenges and problems, many of which cannot be solved with thinking patterns from an old industrial-based economy. A fundamental shift in thinking patterns consistent with a new emerging world of work must take place. This change in thinking represents a fundmental shift from traditional and linear ways of seeing the world (worldview), to more holistic ways of seeing the world. In this investigation the word paradigm was used to define how people see their world. A paradigm shift is defined as a change in how a person sees their world: a change from an old to new or different way of viewing the world. Those individuals who are the first to shift their paradigm are called paradigm pioneers. These individuals do not only shift their ways of seeing the world, but they also begin to act and behave in ways consistent with the new paradigm. Thus far the research literature has adequately described the concepts of paradigms and paradigm shifts. However, little is known regarding how people actually and eventually make a shift. As it will be important for each individual to make a personal paradigm shift, then it will be extremely valuable to learn more about the process itself. The purpose of this investigation was to explore these issues in more detail and specifically, describe the experience of paradigm shifts and explore the experience of paradigm pioneers. A qualitative research methodology involving in-depth interviews was used to investigate the experiences of four participants identified as paradigm pioneers. It is interesting to note that the participants in this study did not describe an allencompassing paradigm shift. In fact, each participant, defined a paradigm shift in several different ways. They did relate several examples of paradigm shifts. However, even among these examples, there was a high degree of variability. The findings of this investigation centered upon the participants' experience as pioneers. Each pioneer shared many of the same qualities, the first quality of which described how these pioneers dealt with change. I called this a change-sense quality. The pioneers viewed change in an open and positive manner, and were also aware of change taking place in their world. Finally, they displayed an understanding of change, and a bias to take positive action in the face it. The participants also shared an inner quality. The four pioneers demonstrated a personal purpose and vision, and were selfdirected individuals. They also had an innate curiosity which translated into a love of learning. They also displayed a quality where relationships with others were highly valued. Relationships were important to the pioneers because they played a support role to help them deal with the challenges of being a pioneer. Pioneers also valued relationships because, they relied on others to make change happen. The above mentioned qualities enabled pioneers to be effective in a changing world of work. The findings from this investigation have many implications for research and practice. First, the concept of paradigms and paradigm shifts must be further researched. A great deal more must be learned in order to better understand the kind of shift individuals must make to be effective in the new world of work. Second, the qualities displayed by pioneers are important for all members of the world of work to develop. The qualities shared by pioneers appeared to represent an enduring set of traits that can possibly help individuals deal more positively with uncertainty and rapid change taking place in today's North American world of work.

The production of school numbers (1871-1931): contributions to a critical approach to statistical sources in History of Education

This article intends to contribute to the reflection on the Educational Statistics as being source for the researches on History of Education. The main concern was to reveal the way Educational Statistics related to the period from 1871 to 1931 were produced, in central government. Official reports - from the General Statistics Directory - and Statistics yearbooks released by that department were analyzed and, on this analysis, recommendations and definitions to perform the works were sought. By rending problematic to the documental issues on Educational Statistics and their usual interpretations, the intention was to reduce the ignorance about the origin of the school numbers, which are occasionally used in current researches without the convenient critical exam.

Air Pollution and Mortality in Latin America The Role of Education

Background: People with less education in Europe, Asia, and the United States are at higher risk of mortality associated with daily and longer-term air pollution exposure. We examined whether educational level modified associations between mortality and ambient particulate pollution (PM(10)) in Latin America, using several timescales. Methods: The study population included people who died during 1998-2002 in Mexico City, Mexico; Santiago, Chile; and Sao Paulo, Brazil. We fit city-specific robust Poisson regressions to daily deaths for nonexternal-cause mortality, and then stratified by age, sex, and educational attainment among adults older than age 21 years (none, some primary, some secondary, and high school degree or more). Predictor variables included a natural spline for temporal trend, linear PM(10) and apparent temperature at matching lags, and day-of-week indicators. We evaluated PM(10) for lags 0 and I day, and fit an unconstrained distributed lag model for cumulative 6-day effects. Results: The effects of a 10-mu g/m(3) increment in lag 1 PM(10) on all nonextemal-cause adult mortality were for Mexico City 0.39% (95% confidence interval = 0.131/-0.65%); Sao Paulo 1.04% (0.71%-1.38%); and for Santiago 0.61% (0.40%-0.83%. We found cumulative 6-day effects for adult mortality in Santiago (0.86% [0.48%-1.23%]) and Sao Paulo (1.38% [0.85%-1.91%]), but no consistent gradients by educational status. Conclusions: PM(10) had important short- and intermediate-term effects on mortality in these Latin American cities, but associations did not differ consistently by educational level.

Can the CAMCOG be a good cognitive test for patients with Alzheimer`s disease with low levels of education?

Background: The Cambridge Cognitive Examination (CAMCOG) is a useful test in screening for Alzheimer`s disease (AD). However, the interpretation of CAMCOG cut-off scores is problematic and reference values are needed for different educational strata. Given the importance of earlier diagnoses of mild dementia, new cut-off values are required which take into account patients with low levels of education. This study aims to evaluate whether the CAMCOG can be used as an accurate screening test among AD patients and normal controls with different educational levels. Methods: Cross-sectional assessment was undertaken of 113 AD and 208 elderly controls with heterogeneous educational levels (group 1: 1-4 years; group 2: 5-8 years; and group 3: >= 9 years) from a geriatric clinic. submitted to a thorough diagnostic evaluation for AD including the Cambridge Examination for Mental Disorders of the Elderly (CAMDEX). Controls had no cognitive or mood complaints. Sensitivity (SE) and specificity (SP) for the CAMCOG in each educational group was assessed with receiver-operator-characteristic (ROC) curves. Results: CAMCOG mean values were lower when education was reduced in both diagnostic groups (controls - group 1: 87; group 2: 91; group 3: 96; AD - group 1: 63; group 2: 62; group 3: 77). Cutoff scores for the three education groups were 79, 80 and 90, respectively. SE and SP varied among the groups (group 1: 88.1% and 83.5%; group 2: 84.6% and 96%; group 3: 70.8% and 90%). Conclusion: The CAMCOG can be used as a cognitive test for patients with low educational level with good accuracy. Patients with higher education showed lower scores than previously reported.

Verbal fluency in the detection of mild cognitive impairment and Alzheimer`s disease among Brazilian Portuguese speakers: the influence of education

Background: Verbal fluency (VF) tasks are simple and efficient clinical tools to detect executive dysfunction and lexico-semantic impairment. VF tasks are widely used in patients with suspected dementia, but their accuracy for detection of mild cognitive impairment (MCI) is still under investigation. Schooling in particular may influence the subject`s performance. The aim of this study was to compare the accuracy of two semantic categories (animals and fruits) in discriminating controls, MCI patients and Alzheimer`s disease (AD) patients. Methods: 178 subjects, comprising 70 controls (CG), 70 MCI patients and 38 AD patients, were tested on two semantic VF tasks. The sample was divided into two schooling groups: those with 4-8 years of education and those with 9 or more years. Results: Both VF tasks - animal fluency (VFa) and fruits fluency (VFf) - adequately discriminated CG from AD in the total sample (AUC = 0.88 +/- 0.03, p < 0.0001) and in both education groups, and high educated MCI from AD (VFa: AUC = 0.82 +/- 0.05, p < 0.0001; VFf: AUC = 0.85 +/- 0.05, p < 0.0001). Both tasks were moderately accurate in discriminating CG from MCI (VFa: AUC = 0.68 +/- 0.04, p < 0.0001 - VFf:AUC = 0.73 +/- 0.04, p < 0.0001) regardless of the schooling level, and MCI from AD in the total sample (VFa: AUC = 0.74 +/- 0.05, p < 0.0001; VFf: AUC = 0.76 +/- 0.05, p < 0.0001). Neither of the two tasks differentiated low educated MCI from AD. In the total sample, fruits fluency best discriminated CG from MCI and MCI from AD; a combination of the two improved the discrimination between CG and AD. Conclusions: Both categories were similar in discriminating CG from AD; the combination of both categories improved the accuracy for this distinction. Both tasks were less accurate in discriminating CG from MCI, and MCI from AD.

A review of the impact of education and prior experience on new venture performance

The importance of education and experience to the successful performance of new firms is well recognized both by management practitioners and academics. Yet empirical research to support the significance of this relationship is inconclusive. This paper discusses theories describing the relationship between education and experience and firm performance. It also analyses and classifies the differing measures of performance, education and experience, and compares the results of multiple studies undertaken between 1977 and 2000. Possible reasons for conflicting results are identified, such as lack of sound theoretical bases that relate education and experience to performance, varying definitions of the key variables and the diversity of measures used. Finally, a framework is developed that incorporates variables that interact with experience and education to influence new venture performance.

Student stress and quality of education

Today, managers are increasingly interested in knowing how the work in organizations aftects employees' health. Less common is the interest in stress erupting in the academic community - among students, faculty and administrators. The authors present a reflection paper focused on student stress. In this paper, they first examine McLean 's model of context, vulnerability and stressors. This model provides the framework for the student surveys and for the entire paper. Based on the students surveys, an assessment is made of how asma" group of students are coping with stress. The paper fina"y suggests what can be done by students, faculty, and administrators to insta" and/or improve social support systems that might reduce the harmful eftects of stress on students and thus impact the quality of education.
