Relationship between laboratory-measured variables and heart rate during an ultra-endurance triathlon

The aim of the present study was to examine the relationship between the performance heart rate during an ultra-endurance triathlon and the heart rate corresponding to several demarcation points measured during laboratory-based progressive cycle ergometry and treadmill running. Less than one month before an ultra-endurance triathlon, 21 well-trained ultra-endurance triathletes (mean +/- s: age 35 +/- 6 years, height 1.77 +/- 0.05 in, mass 74.0 +/- 6.9 kg, (V) over dot O-2peak = 4.75 +/- 0.42 1 center dot min(-1)) performed progressive exercise tests of cycle ergometry and treadmill running for the determination of peak oxygen uptake ((V) over do O-2peak), heart rate corresponding to the first and second ventilatory thresholds, as well as the heart rate deflection point. Portable telemetry units recorded heart rate at 60 s increments throughout the ultra-endurance triathlon. Heart rate during the cycle and run phases of the ultra-endurance triathlon (148 +/- 9 and 143 +/- 13 beats center dot min(-1) respectively) were significantly (P < 0.05) less than the second ventilatory thresholds (160 +/- 13 and 165 +/- 14 beats center dot min(-1) respectively) and heart rate deflection points (170 +/- 13 and 179 +/- 9 beats center dot min(-1) respectively). However, mean heart rate during the cycle and run phases of the ultra-endurance triathlon were significantly related to (r = 0.76 and 0.66; P < 0.01), and not significantly different from, the first ventilatory thresholds (146 +/- 12 and 148 +/- 15 beats center dot min(-1) respectively). Furthermore, the difference between heart rate during the cycle phase of the ultra-endurance triathlon and heart rate at the first ventilatory threshold was related to marathon run time (r = 0.61; P < 0.01) and overall ultra-endurance triathlon time (r = 0.45; P < 0.05). The results suggest that triathletes perform the cycle and run phases of the ultra-endurance triathlon at an exercise intensity near their first ventilatory threshold

Microhardness mapping and the hardness-yield strength relationship in high-pressure diecast magnesium alloy AZ91

Microhardness maps of cross-sections of high-pressure diecast test bars of AZ91 have been determined. Specimens with rectangular cross-sections, 1, 2 and 3 mm thick, or with a circular cross-section 6.4 mm in diameter, have been studied. The hardness is generally higher near the edges in all specimens, and more so near the corners of the rectangular specimens. The hardness at the center of the castings is generally lower, due to a coarser solidification microstructure and the concentration of porosity. The evidence confirms that the surface of the castings is harder than the core, but it does not support the concept of a skin with a sharp. and definable boundary. This harder layer is irregular in hardness and depth and is not equally hard on opposite sides of the casting. The mean hardness obtained by integrating the microhardness maps over the entire cross-section increased with decreasing thickness of the bars, and was found to be in good correlation with each bar's yield strength.

Quality-of-life in children and adolescents with cystic fibrosis managed in both regional outreach and cystic fibrosis center settings in Queensland

To assess the health-related quality-of-life (HRQOL) of children/adolescents with cystic fibrosis (CF) and compare HRQOL in children managed by cystic fibrosis outreach service (CFOS) with those treated in a cystic fibrosis center (CFC). To compare HRQOL of children with CF in Queensland with previously published HRQOL data from the United States and examine the relationship between HRQOL scores and pulmonary function. Study design: Participants were children/adolescents with CF and their parents managed by the Royal Children’s Hospital Queensland at a CFC or CFOS. Two HRQOL surveys were used: PedsQL™ and Cystic Fibrosis Questionnaire (CFQ). Results: There were 91 CFC and 71 CFOS participants with similar demographics. PedsQL™ total summary score was statistically higher in CFOS, P = .05. There was no significant difference in CFQ scores between groups. Queensland parents reported lower HRQOL for their children compared with US parents (P

SMEs in a globalised world:survival and growth strategies on Europe's geographical periphery

This insightful book shows how small and medium enterprises (SMEs) from some of the traditionally less dynamic peripheral economies of the 'old' EU - namely Ireland, Italy, Portugal and Spain - have responded to the twin challenges of globalisation and industrial restructuring. Through a series of unique case studies the contributing authors discuss how these economies, and in particular the SME sector, can be transformed. The book begins by examining the key drivers of the globally competitive SME sector in the EU, before moving on to explore the relationship between multinational enterprises (MNEs), SMEs and industrial development. The authors investigate important policy implications and provide lessons for SME development and growth. With empirical and theoretical contributions on SMEs in both the manufacturing and the services sectors, this essential book will be invaluable for researchers and policymakers in small business economics and management. Postgraduate students of entrepreneurship, business economics, industrial economics and European studies will appreciate this unique set of insights.

Miami Interpretive Center

The rapid growth and diversity of the City of Miami has left its inhabitants somewhat lost in a city with much to offer. The challenge of this thesis is to provide Miami with an architectural proposal that enhances an understanding of its own urban context through both its form and function. Specifically, the Miami Interpretive Center (M.I.C.) will offer the community a research center for the study of the city, as well as a cultural and exhibition center to allow for the expression of its ever-changing character. With the use of historical context, site relationship and taking advantage of views, the M.I.C. will educate its users towards a better understanding of the city. The goal of the M.I.C. is to establish a center for the continued analysis of the city origins, and growth, while serving as a basis for future initiatives. It will invite the public to seek a new context for the investigation of the natural, urban, cultural, spiritual and political environment that formed the city while participating in the shaping of its future. ^

Organized labor and U.S. foreign policy: The Solidarity Center in historical context

During the Cold War the foreign policy of the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO), was heavily criticized by scholars and activists for following the lead of the U.S. state in its overseas operations. In a wide range of states, the AFL-CIO worked to destabilize governments selected by the U.S. state for regime change, while in others the Federation helped stabilize client regimes of the U.S. state. In 1997 the four regional organizations that previously carried out AFL-CIO foreign policy were consolidated into the American Center for International Labor Solidarity (Solidarity Center). My dissertation is an attempt to analyze whether the foreign policy of the AFL-CIO in the Solidarity Center era is marked by continuity or change with past practices. At the same time, this study will attempt to add to the debate over the role of non-governmental organizations (NGOs) in the post-Cold War era, and its implications for future study. Using the qualitative "process-tracing" detailed by of Alexander George and Andrew Bennett (2005) my study examines a wide array of primary and secondary sources, including documents from the NED and AFL-CIO, in order to analyze the relationship between the Solidarity Center and the U.S. state from 2002-2009. Furthermore, after analyzing broad trends of NED grants to the Solidarity Center, this study examines three dissimilar case studies including Venezuela, Haiti, and Iraq and the Middle East and North African (MENA) region to further explore the connections between U.S. foreign policy goals and the Solidarity Center operations. The study concludes that the evidence indicates continuity with past AFL-CIO foreign policy practices whereby the Solidarity Center follows the lead of the U.S. state. It has been found that the patterns of NED funding indicate that the Solidarity Center closely tailors its operations abroad in areas of importance to the U.S. state, that it is heavily reliant on state funding via the NED for its operations, and that the Solidarity Center works closely with U.S. allies and coalitions in these regions. Finally, this study argues for the relevance of "top-down" NGO creation and direction in the post-Cold War era.

A retrospective-longitudinal examination of the relationship between apportionment of seat time in community-college algebra courses and student academic performance

During the past decade, there has been a dramatic increase by postsecondary institutions in providing academic programs and course offerings in a multitude of formats and venues (Biemiller, 2009; Kucsera & Zimmaro, 2010; Lang, 2009; Mangan, 2008). Strategies pertaining to reapportionment of course-delivery seat time have been a major facet of these institutional initiatives; most notably, within many open-door 2-year colleges. Often, these enrollment-management decisions are driven by the desire to increase market-share, optimize the usage of finite facility capacity, and contain costs, especially during these economically turbulent times. So, while enrollments have surged to the point where nearly one in three 18-to-24 year-old U.S. undergraduates are community college students (Pew Research Center, 2009), graduation rates, on average, still remain distressingly low (Complete College America, 2011). Among the learning-theory constructs related to seat-time reapportionment efforts is the cognitive phenomenon commonly referred to as the spacing effect, the degree to which learning is enhanced by a series of shorter, separated sessions as opposed to fewer, more massed episodes. This ex post facto study explored whether seat time in a postsecondary developmental-level algebra course is significantly related to: course success; course-enrollment persistence; and, longitudinally, the time to successfully complete a general-education-level mathematics course. Hierarchical logistic regression and discrete-time survival analysis were used to perform a multi-level, multivariable analysis of a student cohort (N = 3,284) enrolled at a large, multi-campus, urban community college. The subjects were retrospectively tracked over a 2-year longitudinal period. The study found that students in long seat-time classes tended to withdraw earlier and more often than did their peers in short seat-time classes (p < .05). Additionally, a model comprised of nine statistically significant covariates (all with p-values less than .01) was constructed. However, no longitudinal seat-time group differences were detected nor was there sufficient statistical evidence to conclude that seat time was predictive of developmental-level course success. A principal aim of this study was to demonstrate—to educational leaders, researchers, and institutional-research/business-intelligence professionals—the advantages and computational practicability of survival analysis, an underused but more powerful way to investigate changes in students over time.

The relationship between vegetation and modern pollen assemblages on Mount Paggeo (NE Greece)

In this study, we investigated the relationship between vegetation and modern-pollen rain along the elevational gradient of Mount Paggeo. We apply multivariate data analysis to assess the relationship between vegetation and modern-pollen rain and quantify the representativeness of forest zones. This study represents the first statistical analysis of pollen-vegetation relationship along an elevational gradient in Greece. Hence, this paper improves confidence in interpretation of palynological records from north-eastern Greece and may refine past climate reconstructions for a more accurate comparison of data and modelling. Numerical classification and ordination were performed on pollen data to assess differences among plant communities that beech (Fagus sylvatica) dominates or co-dominates. The results show a strong relationship between altitude, arboreal cover, human impact and variations in pollen and nonpollen palynomorph taxa percentages.

What is social innovation? The paradigm shift and its relationship with Social Work

Innovation is a fundamental part of social work. In recent years there has been a shift in the innovation paradigm, making it easier to accept this relationship. National and supranational policies aimed at promoting innovation appear to be specifically guided by this idea. To be able to affirm this hypothesis, it is necessary to review the perception that social workers have of their duties. It is also useful to examine particular cases that show how such social innovation arises.

Sound Art and Public Engagement in the Built Environment: Reflections from an Architecture Center

This article explores the deployment of sound in architectural-curatorial and community engagement contexts through the work of PLACE, a multidisciplinary not-for-profit architecture center in Belfast, Northern Ireland. The author, who worked with PLACE and contributed to the projects discussed here, contextualizes architecture centers and their relationship with sound before examining the specific case of sound and sound art in Northern Ireland and case studies of projects delivered by PLACE. Specifically, the article evaluates two sound installation artworks and three community engagement projects for young audiences. As a means of curating urbanism and architecture, sound-art-as-public-art affords useful strategies to examine, describe or critique the environment as alternatives to traditional architecture exhibition formats. Sound’s temporality and materiality allow sound art works to exist as temporary sculptural interventions in the urban sphere, with attendant implications for public art procurement and urban acoustics. Rich territories of engagement are opened when using sound in a community participatory context.

The Changing Relationship between Supervisors and Subordinates: How Managing This Relationship Evolves over Time

Understanding how the relationship between a subordinate and manager develops over time has been a critical matter both for academics and for business. In both academic journals and industry publications, some writers have argued that the relationship is driven by perceptions of fairness and treatment, and that developing the relationship can lead to better performance. Others have argued that higher performers get better treatment and resources, which results in superior relationships with their managers. There is really no clear answer of what comes first—perceptions of fairness, satisfaction with the supervisor, or job performance—and which leads to which.

Peripheral communities of the Eastern Lau Spreading Center and Valu Fa Ridge: community composition, temporal change and comparison to near-vent communities

Western Pacific hydrothermal vents will soon be subjected to deep-sea mining and peripheral sites are considered the most practical targets. The limited information on community dynamics and temporal change in these communities makes it difficult to anticipate the impact of mining activities and recovery trajectories. We studied community composition of peripheral communities along a cline in hydrothermal chemistry on the Eastern Lau Spreading Center and Valu Fa Ridge (ELSC-VFR) and also studied patterns of temporal change. Peripheral communities located in the northern vent fields of the ELSC-VFR are significantly different from those in the southern vent fields. Higher abundances of zoanthids and anemones were found in northern peripheral sites and the symbiont-containing mussel Bathymodiolus brevior, brisingid seastars and polynoids were only present in the northern peripheral sites. By contrast, certain faunal groups were seen only in the southern peripheral sites, such as lollipop sponges, pycnogonids and ophiuroids. Taxonomic richness of the peripheral communities was similar to that of active vent communities, due to the presence of non-vent endemic species that balanced the absence of species found in areas of active venting. The communities present at waning active sites resemble those of peripheral sites, indicating that peripheral species can colonize previously active vent sites in addition to settling in the periphery of areas of venting. Growth and mortality were observed in a number of the normally slow-growing cladorhizid stick sponges, indicating that these animals may exhibit life history strategies in the vicinity of vents that differ from those previously recorded. A novel facultative association between polynoids and anemones is proposed based on their correlated distributions.
