Understanding the fluctuations of perceived authenticity in cultural tourism : an investigation of Bali and Alsace contexts
2022
The marketing of cultural tourism faces a dilemma between maximizing the economic return and nurturing the culture’s social functions. It needs to attract segments driven by cultural motifs, through a differentiation based on authenticity. Perceived authenticity changes over a time, but how it does remains elusive to researchers. This research investigated fluctuations of existential authenticity in cultural tourists in Bali. Participants were purposively and conveniently-sampled among visitors of cultural attractions. It comprised two stages: qualitative for building the model, and quantitative fortesting the variables. The first employed Grounded Theory interviewing 24 visitors, found the…
Introduction to Immediate Loading in Implantology
2019
Branemark traditional recommendation was to perform implant rehabilitation in two stages: the first entry was only for implant placement; after 3–6 months of undisturbed submerged healing for mandible and maxilla, respectively, a second surgical entry would have allowed loading of the implants. The rationale behind this approach was that implant micro-movements as consequence by an inadequate primary stability, caused by functional forces at the bone-implant interface in the early wound healing stages, could have induced fibrous tissue formation rather than new bone, eventually causing clinical failure. The main request was to reduce the overall rehabilitation time from surgery to final res…
Identity Development in Adulthood: Introduction
2016
In line with Erikson’s suggestions, increasing empirical evidence substantiates that considerable identity development takes place over the course of adulthood. What then does identity development during adulthood entail? The key findings of adult identity formation from four culturally different countries, and the challenges of analyzing the complex concept of identity are discussed. Although a wide array of identity measures are available, they have not been sufficiently validated for use with middle-aged or older adults. Additionally, different measures may yield results that are not comparable across studies. More studies are needed on adult identity development in populations represent…
An optimised multi-host trematode life cycle: fishery discards enhance trophic parasite transmission to scavenging birds
2016
Overlapping distributions of hosts and parasites are critical for successful completion of multi-host parasite life cycles and even small environmental changes can impact on the parasite's presence in a host or habitat. The generalist Cardiocephaloides longicollis was used as a model for multi-host trematode life cycles in marine habitats. This parasite was studied to quantify parasite dispersion and transmission dynamics, effects of biological changes and anthropogenic impacts on life cycle completion. We compiled the largest host dataset to date, by analysing 3351 molluscs (24 species), 2108 fish (25 species) and 154 birds (17 species) and analysed the resultant data based on a number of …
Deterministic chaos and the first positive Lyapunov exponent: a nonlinear analysis of the human electroencephalogram during sleep
1993
Under selected conditions, nonlinear dynamical systems, which can be described by deterministic models, are able to generate so-called deterministic chaos. In this case the dynamics show a sensitive dependence on initial conditions, which means that different states of a system, being arbitrarily close initially, will become macroscopically separated for sufficiently long times. In this sense, the unpredictability of the EEG might be a basic phenomenon of its chaotic character. Recent investigations of the dimensionality of EEG attractors in phase space have led to the assumption that the EEG can be regarded as a deterministic process which should not be mistaken for simple noise. The calcu…
Efficacy of leukotriene receptor antagonist in chronic urticaria. A double-blind, placebo-controlled comparison of treatment with montelukast and cet…
2001
Background The cause and pathogenesis of chronic urticaria are still poorly understood. IgE-independent reactions, are common in adult patients with chronic urticaria, who have daily spontaneous occurrence of weals. H1-receptor antagonists (antihistamines) are the major class of therapeutic agents used in the management of urticaria and angioedema. Nevertheless, chronic urticaria is often difficult to treat and may not be controlled by antihistamines alone. It has been postulated that mediators other than histamine, such as kinins, prostaglandin and leukotrienes, may be responsible for some of the symptoms in urticaria which are not controlled by antihistamines. In this study, which was ran…
Effects of bioheapleaching technology utilizing metal mine emissions on fish in boreal freshwaters
2018
Emissions from metal mining activities are known to deteriorate the quality of aquatic habitats and impair the condition and reproductive potential of fish. Metal extraction by biomining methods has been considered to cause fewer emissions, but for example in Finland, the impacts of a bioheapleaching technology utilizing metal mine on the local freshwaters have been substantial. In this thesis, the impacts of the bioheapleaching mine emissions on three native fish species, brown trout (Salmo trutta) European perch (Perca fluviatilis) and whitefish (Coregonus lavaretus pallasi), were investigated. Manganese and sulphate concentrations have been elevated in the mining impacted waters, and in …
The Understanding of Human Rights and Rule of Law from the Perspective of Kohlberg’s Theory
2015
Human rights, democracy and the rule of law are considered to be the foundations of the normative order of modern societies (Habermas, 1996). Even though the universal validity of human rights is often criticized, they represent an ethical minimum consensus of the global society as conventions on human rights have been ratified by more than 150 states.
Self-esteem: An antecedent or a consequence of social support and psychosomatic symptoms? Cross-lagged associations in adulthood
2008
Abstract This study investigated the relationships of self-esteem with social support and psychosomatic symptoms in cross-lagged longitudinal data with two measurement points and a time lag of 6 years. Two hundred thirteen participants were drawn from the ongoing Jyvaskyla Longitudinal Study of Personality and Social Development, Finland. The present study focused on data collected by questionnaires at ages 36 and 42. The cross-lagged analyses of Structural Equation Modeling (SEM) indicated that high self-esteem at age 36 predicted high social support 6 years later and simultaneously, but to a lesser extent, high social support at age 36 predicted high self-esteem at age 42. In addition, lo…
¿Naturalizar la idea de justicia? Una respuesta crítica desde la teoría moral de Jürgen Habermas
2017
The aim of this paper is to study critically, with the help of Habermas´s moral theory, the current naturalistic approach to morality —which is based on both the evolutionary theory and neuroscience—. In doing so it will be explained the specifically moral use of practical reason, as Habermas propose; it will be compared this moral use with Kohlberg's postconventional stage of moral development; and it will be claimed that naturalistic approach cannot explain this stage, that can be understood as specific justice area.
