Heart Rate Holter Monitoring of 6- and 7-Year Old Children with Insulin Dependent Diabetes Mellitus Cardiovascular and Short Term Metabolic Response to Exercise: A Pilot Study

Abstract

This study examined whether gender and/or training were related to the exercise-induced changes in plasma concentrations of growth hormone (GH), prolactin (PRL), triiodothyronine (T₃), and thyroxine (T₄). Twenty subjects (male and female 10-km runners; untrained males and females) ran on a treadmill for 30 win at 80% of previously determined maximum heart rate. Blood samples were taken through an indwelling catheter from an antecubital vein at ?30, 0, +15, +30 min of the test and 30 min of recovery. Reded temperature rose significantly (p < .01) at +15 and +30 min with concomitant rise in GH concentration, but PRL, T₃, and T₄ were not affected by the exercise. We concluded that a 30-min run at 80% of maximum heart rate is associated with higher concentrations of GH but not of PRL, T₃, and T₄ Neither training state nor gender affected the aforementioned results.     

Professionalization as an advocacy strategy: a content analysis of Canadian child care social movement organizations’ 2008 discursive resources

Do early childhood education and care (ECEC) professionals make good advocates? Canadian advocates have fought for better child care policies since the mid-1940s. What has happened to this advocacy with the recent increased professionalization of the ECEC sector? How does increased professionalization limit, innovate or expand advocacy strategies? This content analysis of seven Canadian child care social movement organizations’ discursive resources in 2008 examines how different types of child care social movement organizations communicated their positions to their members and the public to manage a changing economic and political climate. Preliminary findings indicate that both ECEC workforce sector associations and grassroots organizations shared common advocacy messages, played down problems associated with a market approach to child care, and framed child care as a business case in their messaging. The authors suggest this reflects a nascent discursive move towards the professionalization of Canadian child care movement advocacy messages.

Education as a mechanism for conflict resolution in Northern Ireland

How education systems operate in divided societies is an increasingly important question for academics and educational practitioners as well as for governments. The question is particularly pertinent in post‐conflict societies, where education is a key mechanism for resolving conflict between divided communities. Using Northern Ireland as a case study, this article sheds new light on the role of education in conflict resolution by examining the long‐term impact of segregated and integrated education on attitudes towards community relations and levels of contact between the Protestant and Catholic communities. The results suggest that individuals who had attended an integrated school are significantly more likely to have friends and neighbours from across the religious divide and that these friendship networks translate into a more optimistic view of future community relations. This is not the case, however, when kinship networks are considered. The evidence from Northern Ireland suggests that the education system can be a source of both conflict and cohesion depending on the nature of the school system as well as the particular source of division to be addressed.     

The Growth of International Student Enrollment at Community Colleges and Implications

An emerging trend today is the increased enrollment of international students at community colleges. International students look to American community colleges as a steppingstone to achieving an education that might otherwise be beyond their reach. They are attracted to the community college by the lower tuition costs, opportunities for guaranteed transfer to a four-year university, and the opportunity to study at a variety of geographical locations throughout the United States. The purpose of this qualitative study was to examine the reasons that international students choose to study at community colleges and to consider the implications for community colleges at a time when funding, services, and growth opportunities have been severely restricted. Suggestions for further research are also included.     

Relevant and timely learning for busy leaders

Lord Leitch was commissioned by the Chancellor in 2004 with a remit to ‘identify the UK's optimal skills mix in 2020 to maximise economic growth, productivity and social justice and to consider the policy implications of achieving the level of change required.’ In the 2006 Budget, the Chancellor asked Lord Leitch to consider how to better integrate employment and skills services at a local level. In his final report ‘Prosperity for all in the global economy – world class skills’ Leitch states the need to further improve management and leadership skills in the UK recommending that the UK should aim to be a world leader on skills by 2020. One of the key ways to maximize economic growth is through leadership of small and medium enterprise. In response to this Leitch report and in conjunction with the Sector Skills Councils, an action learning opportunity was made available for leaders in the retail and leisure sectors in Merseyside. Alongside the government also highlighted a need for skill development in ‘inspirational’ leadership in particular. To make learning and development ‘relevant and timely’ for busy leaders, action learning is often a preferred option. This paper looks at three particular aspects of using action learning with leaders in the retail and leisure sectors. Firstly, how commitment to engage with the process was created and fostered, in light of work pressures and long working hours. Secondly, the factors that encouraged each member to feel, and act upon, a sense of responsibility for each others' learning and development, rather than just their own, and, thirdly, a frank look at some of the difficulties which arose which could have threatened the effectiveness of the learning.     

A method to integrate patterned electrospun fibers with microfluidic systems to generate complex microenvironments for cell culture applications

The properties of a cell’s microenvironment are one of the main driving forces in cellular fate processes and phenotype expression invivo. The ability to create controlled cell microenvironments invitro becomes increasingly important for studying or controlling phenotype expression in tissue engineering and drug discovery applications. This includes the capability to modify material surface properties within well-defined liquid environments in cell culture systems. One successful approach to mimic extra cellular matrix is with porous electrospun polymer fiber scaffolds, while microfluidic networks have been shown to efficiently generate spatially and temporally defined liquid microenvironments. Here, a method to integrate electrospun fibers with microfluidic networks was developed in order to form complex cell microenvironments with the capability to vary relevant parameters. Spatially defined regions of electrospun fibers of both aligned and random orientation were patterned on glass substrates that were irreversibly bonded to microfluidic networks produced in poly-dimethyl-siloxane. Concentration gradients obtained in the fiber containing channels were characterized experimentally and compared with values obtained by computational fluid dynamic simulations. Velocity and shear stress profiles, as well as vortex formation, were calculated to evaluate the influence of fiber pads on fluidic properties. The suitability of the system to support cell attachment and growth was demonstrated with a fibroblast cell line. The potential of the platform was further verified by a functional investigation of neural stem cell alignment in response to orientation of electrospun fibers versus a microfluidic generated chemoattractant gradient of stromal cell-derived factor 1 alpha. The described method is a competitive strategy to create complex microenvironments invitro that allow detailed studies on the interplay of topography, substrate surface properties, and soluble microenvironment on cellular fate processes.     

Move over Nelly: lessons from 30 years of employment-based initial teacher education in England

Recruiting, preparing and retaining high-quality teachers are recurrent themes of local, national and international education agendas. Traditional university-led forms of teacher education continue to be challenged, and defended, as nations strive to secure a teaching force equipped to achieve high-quality learning outcomes for all students. One commonly adopted policy solution has been the diversification of teacher preparation routes: the alternative certification agenda. In this article, we examine the entire history of one alternative route in place in England from 1997 to 2012, the Graduate Teacher Programme. Using one example of an employment-based programme, we argue that opportunities to engineer innovative and creative spaces in the face of the current teacher preparation reform agenda need to be seized. This case study, which is contextualised in both the international debates about alternative teacher certification routes and the current policy agenda in England, demonstrates the extent to which successive administrations have failed to learn from the lessons of the past in the rush to recycle policies and claim them as their own.
