Pregnancy postponement and childlessness leads to chronic hypervascularity of the breasts and cancer risk

Epidemiologists have established that women with small families, and particularly nulliparae, are prone to develop breast cancer later in life. We report that physiological mammary hypervascularity may be an intermediate reason against the background that breast-core vascularity is normal in pregnancy but pathological in the vascularisation of cancer. We examined breast ‘core’ vascularity in nulliparae during their potential reproductive life and in parous women after their last birth but before their menopause. Fifty clinically normal pre-menopausal non-pregnant women (100 breasts) were studied daily for one ‘luteal positive’ menstrual cycle. Their parity history varied from zero to five babies. Under controlled domestic conditions each wore a special electronic thermometric bra to automatically record breast ‘core’ temperature changes as a measure of mammary tissue blood flow. In the nulliparae there was a rise of breast vascularity throughout reproductive life. In the parous women, a year or so after each birth, breast vascularity was reset at a lower level than before the pregnancy; thereafter, as in nulliparae, there was progressive increase in mammary vascularity until the menopause

Technological and Personal Problem Solving Styles: Is there a Difference?

This paper from Tain-Fung Wu of the National Changhua University, and Rodney L. Custer and Michael J. Dyrenfurth of the University of Missouri, covers problem solving in technology education. More specifically, the authors present a study that looks at similarities and differences in technological and personal problem solving. Research questions, method, and findings are presented.Â

Technological and Personal Problem Solving Styles: Is there a Difference?

Problem solving, and technological problem solving in particular, is clearly a critical survival skill in our technologically advanced world. Government, business, vocational and technology education leaders have increasingly called for more emphasis on higher-order thinking skills and problem solving in both general and technological areas. The American technology education profession has identified problem solving as the technological method (Savage & Sterry, 1990). Authors outside technology education have also suggested that both general and technology teachers would be well advised to focus on enhancing problem solving skills. Given this, the authors sought to examine several key aspects of problem solving in more depth. Of these, the first was problem solving style. Problem-solving style is defined as a tendency to respond in a certain way while addressing problems and not as the steps employed in actually solving the problem. It has been operationally defined by Heppner (1988) in terms of three distinct dimensions which can be measured by the Problem Solving Inventory (PSI). Collectively, these dimensions (problem-solving confidence, approach/avoidance, and personal control) comprise problem-solving style. Although many educators claim to address problem solving, if the increasing frequency of mention in the literature is to be believed, the portion of citizens who have developed adequate problem solving capabilities is insufficient. It is no coincidence that this inadequacy is occurring at the same time when our society is experiencing a decrease in technological literacy. This problem is all the more critical given that the pace of technological growth is escalating (Dyrenfurth, 1991; Johnson, 1989). Target Audience: 2-4 Year College Faculty/Administrator

A doctorate that works: Non-traditional populations served on both sides of the Atlantic

The innovation imperative faced by western business and industry, as well as by both non-governmental and governmental organizations is well recognized. Business and governmental leaders, economists and educators have all spoken about this urgency. To that end, the institutions represented by the authors have independently evolved doctoral programs on both sides of the Atlantic, to prepare research-informed and technologically-capable leaders for business, industry, and public service.Our nations employ an entire continuum of technologically capable people tasked to generate value in their economies. This continuum consists of growing numbers of people ranging from semi-skilled operatives to exceptionally capable engineers, scientists and leaders at the doctoral level. The focus of this paper is at the high end of this continuum and to describe the characteristics of the population targeted and served by the non-traditional doctoral programs. It is hoped that by drawing attention to this growing population and its importance that this will stimulate the development of additional programs that address this critical need.Educational programs addressing each of the worker groups along the skill continuum are well established, that is, except for those at the doctoral level who wish to pursue and advance their career along technological leadership trajectories in business, industry, and public service. This latter group has not been well served by traditional PhD programs that generally are designed to develop people seeking a career in academia. In the United Kingdom, 98% of the Doctorate graduates are employed in non-academic roles, however the traditional PhD degrees are geared towards preparing researchers for entry into academia. This percentage is similarly high in the USA.But, what are the characteristics of the unserved population which would benefit from a technologically-focused business and industry doctorate? This paper was generated to present the characteristics of people actually served by three such doctoral programs, each at different institutions, and each at different stages of program development: One in its initial launch year, one operating for over six years and one operating since 1974. • XXX University, a mid-western land grant institution in the USA, has developed and gained both institutional and state approval to offer such a doctorate. In securing such approval, an extensive needs assessment was conducted, and this was followed by a soft-start pilot program. Subsequent to these two activities, a proper first cohort was recruited and enrolled. Each of these steps was carefully documented and the characteristics of each of the students involved were researched. • XXX University, in the UK, is in its 6th year of operation, having recruited 5 cohorts and graduated the first one. The lessons learnt from the employment destinations of that first cohort are insightful for those considering the creation of such programs as well as for industry wishing to recruit doctoral graduates from this University/degree. • XXX University, a western land grant institution in the USA, is in its 45th year of operation with multiple graduates. Its records provide evidence over time as to the characteristics of those who pursue such industry-oriented non-traditional doctoral degrees. The purpose of this paper is to present the characteristics of this new population in order to describe it and to derive information that will be useful in guiding further program development to serve such populations even better in terms of both content and accessibility/delivery methods.Among the key characteristics that will be summarized include demographics, age, gender, work experience, employer categories, career goals, specific programmatic goals, barriers to entry into a doctoral program, e.g., residency, and other relevant variables. Subsequently the implications of this population’s characteristics will be presented using the categories of: 1. Content important to build into industry-facing doctoral programs, 2. Delivery methods suitable for enrollees in such programs, 3. Instructional approaches and designs effective in serving such enrollees, 4. Advisement mechanisms and support systems needed to support such enrollees, and, 5. Recruitment strategies to attract the right talent/individuals to the program in order to enhance the capacity of the company/industry/agency where they will find employment OR that is already employing them.</div
