No full textEcosystem Indicators and Landscape Ecology Metrics as a Tool to Evaluate Sustainable Land Planning in ICZM
No full textIn the frame of Integrated Coastal Zone Management (ICZM)
planners need tools to design and assess a sustainable state for the coast. Sustainability
and progress indicator have to be integrated to identify improvements
in the state of coastal zones as a result of ICZM implementation [1].
There are two useful approaches in order to take into account, system property,
complexity and evolution, and integrating humans and bio-geospheres:
system ecology (and ecosystem health concepts, as defined in [2]) and landscape
science and ecology (as defined for example in [3–7]). The holistic approach in
the context of human-nature relations is the real challenge of modern landscape
ecology. It regards the background of increasing environmental problems and
the discussion about sustainability [4] and for sustainability planning [8].
In the paper, it is proposed a brand new synthetic ecosystem indicator suited to
monitoring regeneration plans of coastal zones: the Land Eco-Biodiversity. In order
to have more benchmarks in assessing the state of implementation of a strategy, the
plan, as well as from an ecosystemic point of view, is measured from a landscape
point of view through Landscape Ecology indexes. In fact, the fragmentation of the
landscape is part of the resource efficiency indicators defined by Eurostat in the
context of monitoring the main objectives defined in the Europe 2020 strategy in the

Comparison between Physical Activity and Stress-Related Lifestyle between Orthorexic and Non-Orthorexic University Students: A Case–Control Study
No full text(1) Background: The literature regarding orthorexia nervosa (ON) has well documented the association with other mental disorders, such as obsessive-compulsive and eating disorders. However, the research has not taken into account stress-related behavior and the conduction of physical activity (PA), both structured and unstructured. (2) Methods: In this cross-sectional study, 165 students of the University of Parma (92 females and 74 males) aged between 18 and 49 years old (mean = 24.62 ± 4.81) were consecutively recruited. The ORTO-15 questionnaire was used to divide the total sample into a group without orthorexia (score > 40) and a group with orthorexia (score < 40). All subjects completed the P Stress Questionnaire, and specific items were extrapolated from the Eating Habits Structured Interview (EHSI) to investigate lifestyle, including structured and unstructured PA. (3) Results: Subjects with orthorexia represented 83% of the total sample and reported higher levels of stress-related risk behaviors (i.e., sense of responsibility (t = -1.99, p = 0.02), precision (t = -1.99, p = 0.03), stress disorders (t = -1.38, p = 0.05), reduced spare time (t = -1.97, p = 0.03), and hyperactivity (t = -1.68, p = 0.04)) and a higher frequency of PA (i.e., hours spent training in structured PA, daily (t = -1.68, p = 0.05), weekly (t = -1.91, p = 0.03), and monthly (t = -1.91, p = 0.03), the tendency to carry out physical exercise even if tired (t = -1.97, p = 0.02), and to adhere to unstructured PA (i.e., moving on foot or by bike rather than using transport (t = 1.27, p = 0.04)). (4) Conclusions: The results confirmed the presence of hyperactivity at a motor and behavioral level in people with orthorexia. Further studies are necessary to highlight the causality between ON, stress, and physical activity but it may be possible to hypothesize that "obsessive" physical exercise may not generate the benefits generally known by the literature
A Framework for Sustainable Land Planning in ICZM : Cellular Automata Simulation and Landscape Ecology Metrics
No full textIn the paper, we present a Planning Framework for Integrated Coastal Zone Management (ICZM). The points of strength of the framework are the following:- It is an iterative and participatory process;- It is scenario-based and model-based;- It uses a Spatial Decision Support System (SDSS) as enabling infrastructure;- The SDSS is "powered" by open data and data systematically updated by public bodies.The theoretical starting point is ICZM requires decision support tools to cope with knowledge from multiple sources, interdisciplinarity and multiple scales (e.g., spatial, temporal or organizational) [1]. The 2007 Integrated Maritime Policy for the European Union [2] is a key document to understand the relationship between coastal and marine information and policy implementation. It shows that it is necessary to develop a marine-coastal Decision Support System [3, 4] based on indicators and indices (aggregations of indicators into a synthetic representation), use of Geographic Information Systems, models and multicriteria assessment of scenarios [5, 6]. The system of indices is used to describe the complexity of a coastal system: geo-ecological level, land processes, human society, economy, and coastal uses at multiple scales [5, 7]. Multicriteria assessment is a tool to support social and environmental decisions in the perspective of sustainability and strategic planning [8-11].During the design phase of the SDSS components (basic data, indicators and models), it was performed a review of the Land Use/Land Cover change simulation models. The output of the review was the choice of SLEUTH model [12]. The framework was tested on a study area (Veneto Region - Italy). In the test we coupled SLEUTH with Fragstats [13] for the analysis of landscape ecology metrics
Multidimensional Assessment of Orthorexia Nervosa: A Case-Control Study Comparing Eating Behavior, Adherence to the Mediterranean Diet, Body Mass Index, Psychological Symptoms, and Autonomic Arousal
No full textBackground: The research on orthorexia nervosa (ON) has thoroughly outlined the connection between it and various mental disorders, including obsessive-compulsive disorders and eating disorders, in addition to stress. However, research has not considered psychophysical stress and other measures of psychophysical health, such as adherence to the Mediterranean diet. Methods: This cross-sectional and case-control research involved 63 students from the University of Parma, aged between 18 and 49 years. The ORTO-15 questionnaire was utilized to categorize the entire sample into two groups: one without orthorexia (score > 35) and another with orthorexia (score < 35). All subjects were assessed with the Psychophysiological Stress Profile (PSP) and completed the Eating Disorder Inventory-3 (EDI-3) and the Symptom Checklist-90-Revised (SCL-90-R). In addition, they were interviewed using the PREDIMED questionnaire to assess adherence to the Mediterranean Diet, and their body mass index (BMI) was calculated. Results: Subjects with orthorexia represented 38.10% of the total sample and reported a higher BMI than controls, although the PREDIMED score did not show a difference in adherence to the Mediterranean diet. The EDI-3 highlighted emotional dysregulation and hypercontrol in students with orthorexia, and a dissociation between subjective and objective measures of stress emerged. Particularly, the psychophysiological parameters of skin conductance, heart rate, and heart rate variability showed greater reactivity to stressful stimuli, but no difference was noted in psychological symptoms. Conclusions: These findings confirmed the presence of alterations in eating behavior in people with orthorexia as well as a higher BMI. It was hypothesized that hypercontrol might favor the perception of psychological well-being at a subjective level, although inadequate management of stress emerged at an objective psychophysiological level. Further studies are needed to highlight the causality between ON, hypercontrol, diet, and psychophysical stress, given that students with orthorexia present a dysregulation of emotions associated with greater autonomic arousal
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
