Measured and Perceived Physical Fitness, Intention, and Self-Reported Physical Activity in Adolescence  [PDF]
Timo Jaakkola, Tracy Washington
Advances in Physical Education (APE) , 2011, DOI: 10.4236/ape.2011.12004
Abstract: Objective: The aim of this study was to investigate the associations among measured physical fitness, perceived fitness, intention towards future physical activity and self-reported physical activity through junior high school years. Methods: Study participants included 122 Finnish students who were 13 years old during Grade 7. The sample was comprised of 80 girls and 42 boys from 3 junior high schools (Grades 7-9). During the autumn semester of Grade 7, students completed fitness tests and a questionnaire analyzing self-perception of their physical fitness. The questionnaire delivered at Grade 8 included intention towards future physical activity. At Grade 9 students’ self-reported physical activity levels. Results: Structural Equation Modelling revealed an indirect path from physical fitness to self-reported physical activity via perceived physical fitness and intention towards future physical activity. The model also demonstrated a correlation between perceived physical fitness and physical activity. Squared multiple correlations revealed that perceived physical fitness explained 33 % of the actual physical fitness. Conclusions: The results of this study highlight the role of physical and cognitive variables in the process of adoption of physical activity in adolescence.
Use of Augmented Reality Methods to Support Legal Conflicts in the Planning Process for Wind Turbines Using the Example of the Landscape Conservation Area “Eulenkopf and Surroundings”  [PDF]
Timo Wundsam, Sascha M. Henninger
Energy and Power Engineering (EPE) , 2014, DOI: 10.4236/epe.2014.611030
Abstract: The world’s growing energy demand poses a serious problem. At the same time fossil fuels are finite, which we must work against. Therefore, the Federal Government of Germany has set itself the goal to push forward the use of renewable energy in order to completely do without the generation of nuclear energy by 2023. There are, however, no specific guidelines from the European Directive on the promotion of electricity from renewable energy sources for the internal electricity market regarding how high each share of the different production method should be and, above all, which specific aim should be achieved by the share of wind energy. Nevertheless, it presents a crucial step toward a nuclear phaseout and a concomitant change of course of the Federal Government of Germany in the spring of 2011 regarding the expansion of renewable energy, taking the nuclear catastrophe in Fukushima into account. Using new legal planning approaches, also including the area of Rhineland-Palatinate, opportunities should be provided to make previously protected land available for setting up facilities for the generation of renewable energy. However, it is important to examine the legal situation regarding the installation of these kinds of constructions more detailed, as no general statements can be made. This will be illustrated using the example of the landscape conservation area “Eulenkopf and surrounding area” in the district of Kaiserslautern. The stated goal of the Social Democrat/Green coalition of the federal state government of Rhineland-Palatinate is to considerably expand the generation of electricity from renewable energy sources so that by 2030 at least the entire electricity demand can be covered by those. Due to the enormous potential of wind power, it is therefore necessary to quintuple its share of electricity generation by 2020, compared to 2011 numbers. In order to achieve the desired political objectives, by 2030 the number of turbines has to be increased to around 2650, representing a capacity of 7500 MW. This increase gives reason for boundary conditions to manage the generation of wind energy to be adjusted. This is intended to facilitate management and simultaneously minimise negative effects, such as the “sprawling” of wind turbines.
Synaptic Plasticity and Learning in Animal Models of Tuberous Sclerosis Complex
Timo Kirschstein
Neural Plasticity , 2012, DOI: 10.1155/2012/279834
Abstract: Tuberous sclerosis complex (TSC) is caused by a mutation of either the Tsc1 or Tsc2 gene. As these genes work in concert to negatively regulate the mammalian target of rapamycin (mTOR) kinase which is involved in protein translation, mutations of these genes lead to a disinhibited mTOR activity. Both the clinical appearance of this condition including tumors, cognitive decline, and epileptic seizures and the molecular understanding of the mTOR signaling pathway, not only involved in cell growth, but also in neuronal functioning, have inspired numerous studies on learning behavior as well as on synaptic plasticity which is the key molecular mechanism of information storage in the brain. A couple of interesting animal models have been established, and the data obtained in these animals will be discussed. A special focus will be laid on differences among these models, which may be in part due to different background strains, but also may indicate pathophysiological variation in different mutations. 1. Introduction Tuberous sclerosis complex (TSC) is an inherited disease caused by a heterozygous germ line mutation of either the Tsc1 or Tsc2 gene that is manifested in early childhood. The pathological hallmark of this disorder is the development of hamartomas (benign tumors) arising in a number of organs including the central nervous system [1, 2]. In the brain, TSC lesions typically comprise of cortical tubers, subependymal nodules, and giant cell astrocytomas [3, 4].Hence, common symptoms related to brain lesions are epileptic seizures, mental retardation, multiple neuropsychological impairments, and even autism [5–9]. Consequently, the significant neuropsychiatric morbidity caused by this condition has inspired a number of groups worldwide to study the underlying pathomechanisms aiming to improve our functional understanding of both gene products, named hamartin (Tsc1) and tuberin (Tsc2). These proteins act in concert as a guanosine triphosphate-activating protein (GAP) towards the small G protein Rheb, which is the key regulator of the mammalian target of rapamycin (mTOR) signaling [10, 11]. Since hamartin and tuberin negatively regulate mTOR activity, which in turn phosphorylates and thereby activates important translation factors such as p70 S6 kinase 1 (S6K1) and eukaryote initiation factor 4E-binding protein (eIF4E-BP), a major role of the TSC-mTOR signaling pathway has been suggested for tumorigenesis, and both genes were initially recognized as tumor suppressors [12]. However, increasing evidence has been provided that this pathway is also
A mechanistic model of infection: why duration and intensity of contacts should be included in models of disease spread
Timo Smieszek
Theoretical Biology and Medical Modelling , 2009, DOI: 10.1186/1742-4682-6-25
Abstract: We present an exposure-based, mechanistic model of disease transmission that reflects heterogeneities in contact duration and intensity. Based on empirical contact data, we calculate the expected number of secondary cases induced by an infector (i) for the mechanistic model and (ii) under the classical assumption of a constant per-contact transmission probability. The results of both approaches are compared for different basic reproduction numbers R0.The outcomes of the mechanistic model differ significantly from those of the assumption of a constant per-contact transmission probability. In particular, cases with many different contacts have much lower expected numbers of secondary cases when using the mechanistic model instead of the common assumption. This is due to the fact that the proportion of long, intensive contacts decreases in the contact dataset with an increasing total number of contacts.The importance of highly connected individuals, so-called super-spreaders, for disease spread seems to be overestimated when a constant per-contact transmission probability is assumed. This holds particularly for diseases with low basic reproduction numbers. Simulations of disease spread should weight contacts by duration and intensity.Research has shown that the arrangement of potentially contagious contacts among the individuals of a society is a determining factor of disease spread: Both the repetition and the clustering of contacts diminish the size of an outbreak compared to a random mixing model [1-3]. Further, the epidemic threshold is low if the degree distribution shows a high dispersion [4,5]. In contrast to the vast body of literature that exists on the importance of network structure, only little emphasis has been put on the quality of such potentially contagious contacts, i.e. how long they last and how intensive they are. In fact, mathematical models and computer simulations of disease propagation often assume a constant per-contact transmission probability
Dealing with Ecological Objectives in the Monsu Planning System
Pukkala,Timo;
Silva Lusitana , 2004,
Abstract: the article describes some approaches to incorporate ecological objectives into numerical forest planning when using the monsu software. monsu first simulates alternative treatment schedules for all stands in the planning area, over a user-specified planning horizon. it then seeks the best combination of stands' treatment schedules using numerical optimisation. management objectives are included in the optimisation model either as objective variables or constraints. the ecological variables that monsu can calculate - and which can therefore be considered in optimisation - include (1) ordinary but ecologically oriented forest characteristics such as deadwood volume and area of old forest, (2) a special biodiversity score calculated for the forest, and (3) a set of landscape metrics. landscape metrics are variables that measure the sizes, shapes, relative arrangement and connectivity of habitat patches as well as their total area. the most recent development of monsu has concentrated on the use of landscape metrics, which measure the forest?s ecological quality at the landscape level. a proper scale of ecological planning depends on the size of the territory of the species considered, and it seems that most of the keynote species have rather large territories and therefore require forest rather than stand level evaluations of ecological quality.
Usage and Impact of Controlled Vocabularies in a Subject Repository for Indexing and Retrieval
Timo Borst
Liber Quarterly : The Journal of European Research Libraries , 2012,
Abstract: Since 2009, the German National Library for Economics (ZBW) supports both indexing and retrieval of Open Access scientific publications like working papers, postprint articles and conference papers by means of a terminology web service. This web service is based on concepts organized as a ‘Standard Thesaurus for Economics’ (STW), which is modelled and regularly published as Linked Open Data. Moreover, it is integrated into the institution’s subject repository for automatically suggesting appropriate key words while indexing and retrieving documents, and for automatically expanding search queries on demand to gain better search results. While this approach looks promising to augment ‘off the shelf’ repository software systems in a lightweight manner with a disciplinary profile, there is still significant uncertainty about the effective usage and impact of controlled terms in the realm of these systems. To cope with this, we analyze the repository’s logfiles to get evidence of search behaviour which is potentially influenced by auto suggestion and expansion of scientific terms derived from a discipline’s literature.
De pendel, de kloof en de kliniek.Leendert Bouman (1869-1936) en de ‘psychologische wending’ in de Nederlandse psychiatrie
Timo Bolt
Studium : Tijdschrift voor Wetenschaps- en Universiteits-Geschiedenis , 2010,
Abstract: The pendulum, the gap, and the clinic. Leendert Bouman (1869-1936) and the ‘psychological turn’ in Dutch psychiatry In recent historical literature, the Dutch psychiatrist Leendert Bouman (1869-1936) is named ‘the godfather of psychological psychiatry’. He is regarded as one of the exponents of a shift or ‘pendulum’ movement from a biological-materialistic to a psychological, phenomenological orientation in the Dutch psychiatry of the Interbellum. As a professor of the orthodox calvinist Vrije Universiteit of Amsterdam, he explicitly opposed a ‘soul-less’, biological-reductionist psychiatry. In addition, he played an important part in the introduction and spread of new ‘psychological’ theories and especially Karl Jaspers’ phenomenology in the Netherlands. It is one-sided and misleading, however, to refer to Bouman as a ‘psychological’ psychiatrist. Most of his scientific work was of a neurological and biological nature. He did not see biological (or nomothetic) and psychological (or idiographic) approaches as mutually exclusive, but as necessarily complementary. In this he followed Jaspers’ distinction between and complementary use of the causal connections of psychic life (explanatory psychology) and meaningful psychic connections (psychology of meaning). Boumans pluralist orientation was rooted in his fundamentally clinical attitude toward psychiatry. In his view, a psychiatrist was in the first place a clinician. In the clinic, he stressed, a psychiatrist has to view and examine each individual patient in his bio-psycho-social totality. The case of Bouman illustrates that the history of psychiatry is by far richer and more complicated than is suggested by the standard account of that history being characterized by a pendulum movement and a one-dimensional struggle between ‘somatic’ and ‘psychological’ schools. It also suggests that the interaction between theory and clinical practice should be emphasized as an important dynamic factor in the history of psychiatry – next to or even above the dichotomy between ‘biology’ and ‘psychology’.
Governance of protected areas in the Arctic
Timo Koivurova
Utrecht Law Review , 2009,
Abstract: This article analyzes what has been achieved in the Arctic cooperation process – now functioning as the Arctic Council – as regards protected areas in the region. Specifically, the research examines how the work in two of the working groups of the Arctic Council has evolved – the Conservation of Arctic Flora and Fauna (CAFF) and the Protection of the Arctic Marine Environment (PAME). Of particular interest here is CAFF’s Circumpolar Protected Area Network (CPAN), which is designed to coordinate the protected area policies of the Arctic states in their Arctic regions. The main goal of the article is to examine what kinds of functions CPAN is meant to achieve and to discuss whether the project has met its goals. An additional focus is the most recent development in the Arctic Council in the field of marine protected areas (MPAs), which were adopted as one priority action for another working group of the Council, the Protection of the Arctic Marine Environment. All of the developments discussed are evaluated by first identifying the trajectories of protected area activities in the Arctic Council and then discussing the possible ways forward. One salient consideration here is whether normative platforms other than the Arctic Council are better equipped to promote the work on protected areas in the Arctic and what type of policy focus for protected areas could be assumed in the Council.
The EU’s Mediterranean Policies after the Arab Spring: Can the Leopard Change its Spots?
Timo Behr
Amsterdam Law Forum , 2012,
Abstract: For more than two decades, the EU has played a pivotal role in the Mediterranean and North Africa. Although it never yielded the hard power of the United States, the EU’s soft power and its deep social, political and economic ties with the countries of the southern and eastern Mediterranean have provided it with considerable sway in Mediterranean affairs. Through its Euro-Mediterranean Partnership, first launched in 1995, the EU promoted the vision of an open and integrated Mediterranean region that was organically tied to and politically oriented towards the EU.
