Incentives and constraints for archeological tourism: a case study in Spain

ABSTRACT Archeological tourism has great potential for development in numerous destinations. However, literature on archeotourism is scarce and empirical data are very limited. This paper analyzes the incentives to participate in archeotourism and, following the Dual Factor Theory, examines how incentives and constraints may affect the intention to participate in archeotourism in Spain. Data were collected from 521 domestic tourists. An exploratory factor analysis revealed 6 dimensions of incentives: core archeological attraction, aspects that favour the acquisition of historic-cultural knowledge, archeotourism development of the destination, participatory archeological activities, extra archeological attraction and leisure activities. A multiple regression analysis showed that, except leisure activities, all dimensions are crucial incentives for behavioural intention. However, for the oldest age groups, in addition to leisure activities, participatory archeological activities and extra archeological attractions are also not key incentives. On the other hand, among the constraints analyzed, only intrapersonal barriers significantly affect tourists’ intentions.
Novel summation formulas for Jacobi and Gegenbauer polynomials

Thermal equilibrium of a two-dimensional model of mobile point-like charges with pair logarithmic interactions, immersed in a fixed neutralising background, is exactly solvable at a special coupling constant. Assuming gauge invariance of the statistical mechanics and the requirement of local charge neutrality in the bulk regime of the system, the exact solution implies explicit expressions for inverse elements of an infinite interaction matrix. This result is equivalent to new summation formulas over upper index for bilinear products of Jacobi and Gegenbauer polynomials which are complementary to standard completeness relations involving lower indices for these polynomials. We go beyond the physical input and derive multi-variable generalizations of the summation formulas.
Clay‐Graphene Nanoplatelets Functional Conducting Composites

An approach to functionalize graphene‐based materials has been developed by assembling graphene nanoplatelets (GNP) with clay minerals. Under convenient sonomechanical treatment, clay–GNP mixtures may produce very stable water dispersions in particular using sepiolite fibrous clay. While in the absence of clay a rapid decantation of GNP in water is observed, in the presence of sepiolite the resulting dispersions remain stable during months without syneresis effects. Rigid but flexible self‐supported films are easily obtained by filtering of these dispersions. As the electrical percolation threshold corresponds to sepiolite/GNP composites of 0.5:1 in weight, doping these systems with multiwalled carbon nanotubes (MWCNTs) significantly enhances their electrical conductivity. The particular microporosity of the sepiolite component allows interactions with molecules, such as organic dyes, as well as polymers, such as biopolymers, opening the way to functional materials for advanced applications due to their inherent conductivity afforded by the GNP and MWCNTs carbonaceous components. In fact, using very small amount of MWCNT together with GNP can obtain composites with significant electrical conductivity, maintaining the enhanced mechanical properties, at a lower cost.
Effects of Multi-Axial Compression on the Mechanical and Fretting Wear Properties of Ti-45Nb Alloys

Biocompatible β-type Ti-45Nb alloy with a low elastic modulus is promising in alleviating the stress shielding effect of Ti-based hard-tissue replacement implants. In this work, the ultra-fine-grained (UFG) microstructures with different grain sizes were prepared by multi-axial compression (MAC) processing of Ti-45Nb alloys, and the mechanical properties and the fretting wear properties of Ti-45Nb alloys in different grain sizes were investigated. The results show that the yield strength and ultimate tensile strength of the sample processed by 27 passes MAC increase by 76% and 91%, respectively, with an elongation of more than 9%. After MAC processing, the friction coefficient and volume wear rate gradually decrease. In addition, before MAC processing, the Ti-45Nb sample shows a wear mechanism of severe adhesive wear, oxidative wear and fatigue delamination; while after MAC processing, the wear mechanism switches to abrasive wear and slight adhesive wear with slight oxidative wear, indicating that grain refinement helps to improve the anti-fretting properties of Ti-45Nb alloys.
Inequality, autocracy, and sovereign funds as determinants of foreign portfolio equity flows

We identify new country characteristics that influence cross ‐ border equity flows: income inequality, autocracy, and sovereign wealth funds. Using 149 source countries and 34 Organisation for Economic Co ‐ operation and Development (OECD) host countries for 2002 – 2013, we find that OECD host countries receive higher foreign portfolio investment (FPI) inflows from source countries with high income inequality and source countries with a sovereign wealth fund, but lower inflows from autocratic source countries. We argue that concentrated wealth in a society, overseas investments for the benefit of future generations, and political regimes influence FPI. These variables have been understudied though they provide valuable indicators for policy makers and investors. We supplement our core analysis with realistic interactions between these new variables and with the increasing importance of tax havens. Our results hold throughout a variety of robustness checks. the transaction cost between host and source countries. We estimate the models with clustered standard errors, by host country and year, to provide consistent standard errors and appropriate coefficient test statistics.
Relationship between biological age, body dimensions and cardiorespiratory performance in young soccer players

Background: During adolescence, performance in competitive sport is influenced not only by the levels of physical activity, but also by the biological state and body dimensions. Objective: The purpose of our study was to compare cardiorespiratory performance between groups with different biological age in male adolescent soccer players. Methods: Eighty-eight young soccer players (age = 15.9 ± 0.5 years, body height = 176.1 ± 5.6 cm, body weight = 65.4 ± 7.2 kg) performed a vita-maxima protocol on a treadmill. Starting speed was 6 km/h and inclination 1.4%, which were increased linearly every minute, to 11 km/h and to 3.5% respectively (first 5 minutes). Then we increased inclination by 2% every minute until exhaustion. The effect of the biological age on functional indices was examined based on two grouping methods. First, the participants were classified into sub-groups by their morphological (or developmental) age, which is an expression of biological age and evaluates the developmental state of specific body dimensions (body height, body weight, shoulder width, lower arm girth, and hand circumference). Then, from anthropometric and body composition measures three clusters were created, according to the participants' developmental state. For both grouping methods, the groups were: late-maturing, average-maturing, early-maturing. Results: Based on the morphological age grouping method, biologically more advanced athletes achieved greater cardiorespiratory performance (late-maturing: 337 ± 33 W, average maturing: 363 ± 48 W, early maturing: 386 ± 43 W) with higher oxygen uptake (late-maturing: 3529 ± 336 ml/min, average-maturing: 3798 ± 436 ml/min, early-maturing: 3983 ± 541 ml/min) and oxygen pulse (late-maturing: 18.1 ± 1.8 ml/beat, average-maturing: 19.6 ± 2.5 ml/beat, early-maturing: 20.8 ± 2.8 ml/beat). There were no differences in time spent on the treadmill, maximal lactic acid levels, relative power, maximal heart rate, respiratory rate, tidal volume, relative maximal oxygen uptake, maximal ventilation. There were significant differences in weight, plastic index and muscle mass between all the three groups. Differences in cardiorespiratory indices between groups of different maturity status were larger when we grouped the athletes based on cluster analysis compared to the morphological age-based grouping method. Conclusions: During growth and maturation Body dimensions and body (and muscle) mass significantly affect maximal oxygen uptake in young athletes. The inclusion of body composition components in addition to body dimensions increases the explanatory power of biological age on cardiorespiratory performance.
Study of Elastic Behavior of Polylactic Acid with Yanchama Fibers Composite Simulated as Elastic Orthotropic Material

ABSTRACT A new biocomposite material based on polylactic acid (PLA) with meshes of Yanchama fibers is introduced. This bio-based composite was fabricated by compression molding and film-staking process. This new biocomposite material was tested by tensile tests in different directions and was numerically simulated. The composite was simulated as an elastic orthotropic material. The nine constants of elastic orthotropic behavior are calculated from modules of Young measured experimentally. The experiment results and simulations are the same. The results show that the mechanical behavior of the PLA-Yanchama composite under different load solicitudes can be predicted if it is simulated as an orthotropic elastic material.
Contactless Determination of Electric Field in Metal–Insulator–Semiconductor Interfaces by Using Constant DC-Reflectivity Photoreflectance

We applied photoreflectance (PR) spectroscopy for contactless determination of the electric field strength at buried interfaces in metal–insulator–semiconductor (MIS) structures. The PR is an all-optical version of an electromodulated reflectance spectroscopy. The tradeoff of this adoption is that this requires an additional feedback system to eliminate background problems induced by scattered pump light and/or photoluminescence. A microcomputer-based feedback system has been developed for this elimination. Despite the very tiny signal intensity, we successfully attained a sufficiently good signal–noise ratio to determine the electric field strength in oxide-based MIS interfaces that exhibits a large, unwanted photoluminescence signal. The field strength was evaluated to be ca. 0.25 kV/cm.
The Detoxification of Heavy Metals in the Phosphate Tailing-contaminated Soil through Sequential Microbial Pretreatment and Electrokinetic Remediation

ABSTRACT In this paper, the heavy metals (HMs) in the phosphate tailing-contaminated soil were detoxified using the microbial pretreatment in combination with electrokinetic remediation (EKR). This study provides compelling evidence that the sequential usage of the bioleaching and electrokinetics is superior to the individual method for the detoxification of Pb, Cu, Zn, Cd, and As from the contaminated soil. In the sequential system, the detoxification efficiency of Zn was the highest and that of As was the lowest. Except the element As, the detoxification efficiencies of HMs in the sequential system were generally higher than that using the single biological treatment and EKR technique. Bioleaching, generation of the passivation, and migration direction of the ions are concluded as the factors attributable to the final results; and, the initial increase in the inoculation doping of Thiobacillus ferrooxidans considered has no obvious impact on improving the final detoxification efficiency rates.
Synthesis and characterization of poly(arylene ether ketone)s with 3,6-diphenyl-9H-carbazole pendants using C–N coupling reaction

3,6-Diphenyl-9H-carbazole pendants are grafted herein to poly(arylene ether ketone)s (PAEKs) via the Ullmann C–N coupling reaction. To the best of our knowledge, this is the first time that PAEKs containing a carbazole pendant (Cz) have been synthesized through the Ullmann C–N coupling reaction. The high molecular weights of PAEK-Cz (PAEKs with 3,6-diphenyl-9H-carbazole pendants) are inherited from their precursors, owing to the high reactivity of their monomers. The obtained PAEK-Cz-x polymers exhibit good solubility in most common organic solvents and excellent thermal stabilities, with the 5% weight loss temperatures for all products being above 598°C under a nitrogen atmosphere. The glass transition temperatures are all above 199°C and can be controlled by adjusting the feed ratio of monomers. The polymer membranes obtained by the casting method are tough and thus have strong potential for practical applications.
Dynamic analysis of OWT foundation with large diameter monopile under transient storm loading

ABSTRACT To investigate the stability of monopile foundation under dynamic loading, a comprehensive numerical model for the analysis of offshore wind turbines (OWT) foundation under a general transient storm loading is presented in this study. The dynamic stiffness and soil deformation around the large-diameter monopile is simulated using this method. During the numerical analysis, a dynamic boundary surface model of soil is derived instead of the empirical strength degradation. Along the axis direction of the monopile, an intensive study about deformation law of the seabed soil is analysed, moreover, some parameters which may affect the OWT stability and the dynamic stiffness are discussed. Some conclusions can be drawn that the dynamic stiffness and the lateral displacement of the monopile foundation can be obviously improved by increasing the buried depth than the diameter, and the proposed failure mode can well describe the failure law of soil around the monopile due to the dynamic loading.
Dynamic remodeling of presynaptic endoplasmic reticulum is coordinated through actin and microtubule crosstalk and contributes to defective stimulus-response in Spinal Muscular Atrophy

Background Axonal degeneration and defects in neuromuscular neurotransmission represent a pathological hallmark in spinal muscular atrophy (SMA) and other forms of motoneuron disease. These pathological changes do not only base on altered axonal and presynaptic architecture, but also on alterations in dynamic movements of organelles and subcellular structures that are not necessarily reflected by static histopathological changes. In neurons, a highly dynamic endoplasmic reticulum (ER) network exists in the axonal and presynaptic compartment which regulates Ca2+ homeostasis and synapse maintenance. However, the mechanisms of its dynamic regulation and mechanisms of dysfunction that contribute to neurodegeneration remain elusive. Methods Using high resolution microscopy and life imaging of cultured motoneurons from wildtype and a mouse model of spinal muscular atrophy, we investigated the dynamics of the axonal endoplasmic reticulum and ribosome distribution and activation. Results These studies revealed that the dynamic remodeling of ER in axonal filopodia of cultured motoneurons depends mainly on actin cytoskeleton. In Smn -deficient motoneurons, movements of ER in filopodia seems to be more affected than in the growth cone core. In addition, ribosome assembly that happens within seconds after exposure to Brain derived neurotrophic factors (BDNF) is reduced in axon terminals of Smn -deficient motoneurons, and also the association with ER as a response to extracellular stimuli is highly disturbed. Conclusions These findings do not only define a novel function of presynaptic ER in dynamic regulation of local translation. They also implicate impaired dynamic movements of axonal and presynaptic ER as a contributor to the pathophysiology of SMA and possibly also other neurodegenerative diseases.
A Lagrangian-based Floating Macroalgal Growth and Drift Model (FMGDM v1.0): application in the green tides of the Yellow Sea

Abstract. Massive floating macroalgal blooms in the ocean have had an array of ecological consequences; thus, tracking their drifting pattern and predicting their biomass are important for their effective management. However, a high-resolution ecological dynamics model is lacking. In this study, a physical–ecological model, Floating Macroalgal Growth and Drift Model (FMGDM v1.0), was developed to determine the dynamic growth and drift pattern of floating macroalgal, based on the tracking, replication and extinction of Lagrangian particles. The position, velocity, quantity and represented biomass of particles are updated synchronously between the tracking module and the ecological module. The former is driven by ocean flows and sea surface wind, while the latter is controlled by the temperature, salinity, and irradiation. Based on the hydrodynamic models of the Finite-Volume Community Ocean Model and parameterized using a culture experiment of Ulva prolifera, which caused the largest bloom worldwide of the green tide in the Yellow Sea, China, this model was applied to simulate the green tides around the Yellow Sea in 2014 and 2015. The simulation result, distribution and biomass of green tides, was validated using remote sensing observation data and reasonably modeled the entire process of green tide bloom and its extinction from early spring to late summer. Given the prescribed spatial initialization from remote sensing observation, the model could provide accurate short-term (7–8 d) predictions of the spatial and temporal developments of the green tide. With the support of the hydrodynamic model and biological data of macroalgae, this model can forecast floating macroalgae blooms in other regions.
A Scientometric Analysis of Forty-Three Years of Research in Social Support in Education (1977–2020)

This scientometric study examines the overall research trends, publication and citation structures, authorship and collaboration patterns, bibliographic coupling, and productivity patterns in the field of social support in education. Bibliometric data consisting of 545 documents was retrieved from the Scopus database during a period of 43 years (1977–2020) on 1 January 2021. Data analysis was performed using various scientometric software including MS Excel, VOS Viewer, Biblioshiny, CiteSpace and ScientoPy. The results of the study revealed that the first publication on this topic appeared in 1977, however, the major increase was observed during 2017–2020, whereas the maximum number of publications (N = 57) in a single year was published in the year 2020. Similarly, the highest number of citations (n = 1002) were observed in the year 1995 with an average of 334 citations per document. The most productive countries were the United States (N = 194), the United Kingdom (N = 56), and Australia (N = 50 publications). Results further indicated that more than 50.7% of the research in the social support area was done in medicine. Overall, the findings of the study reveal that most of the research in the aforementioned field originated from the developed countries which can be related to the developments in the medical field. The study indicates the importance of social support in the educational context due to an increased trend of inclusion and diversity in the education field. This research is the first bibliometric study in the field of social support in education.
The presentation, recognition and diagnosis of autism in women and girls

Purpose Autistic women and girls have received comparatively less attention within clinical practice and research. Research suggests women tend to be diagnosed later than men, and are more likely to experience misdiagnosis. Design/methodology/approach This paper aims to report a narrative literature review that examines research on the presentation, recognition, and diagnosis of autistic women and girls. Findings Findings suggest that autistic females present differently to males and highlight low recognition of the female presentation of autism among the general public, in social spheres, educational, clinical and forensic settings. This lack of recognition appears to affect the likelihood of females being referred for diagnosis, the reliability of diagnostic assessments and subsequent access to support. Originality/value Recommendations for clinical practice focus on initiatives to increase awareness of the female presentation of autism, improving the diagnostic process for females, increasing female representation within autism training and for future research to support these goals.
Validation of the Italian version of the peritraumatic distress inventory: validity, reliability and factor analysis in a sample of healthcare workers

ABSTRACT Background: Peritraumatic distress as assessed by the Peritraumatic Distress Inventory (PDI), has been consistently shown to predict the development of Posttraumatic Stress Disorder (PTSD) after the exposure to a potentially traumatizing event. Objective: The present study aims to validate the Italian version of the PDI in a sample of Healthcare Workers (HCWs) exposed to COVID-19 related potentially traumatizing events. Method: N = 265 HCWs who repeatedly experienced the deaths of patients during COVID-19 emergency in Italy, were enrolled from the Azienda Ospedaliero-Universitaria Pisana (Pisa, Italy). They completed the PDI, Impact Event Scale – revised (IES-R) and the reactions to losses or upsetting events Trauma and Loss Spectrum – Self Report (TALS-SR) domain. Results: Internal consistency was good with a Cronbach’s alpha coefficient was . 874. The PDI correlated strongly with measures that was conceptually close (TALS-SR reactions to losses or upsetting events domain; r = .723, p < .001). Participants who scored above the cut-off for PTSD reported significantly higher PDI scores than those who did not (6.47 ± 5.25 vs. 19.11 ± 8.291, p < 0.001). The one-month test–retest reliability (n = 21) was excellent (ICC = .997). Finally, factor analyses revealed that the PDI exhibited a single-factor structure. Conclusions: the Italian version of the PDI showed good psychometric proprieties and may be used to detect those at risk for developing PTSD. HIGHLIGHTS Study aim: to validate the Italian version of the peritraumatic distress inventory (PDI). 265 Healthcare Workers completed the PDI the IES-R and the TALS-SR. The reliability, internal consistency validity and the temporal stability were good. The tool presented a one-factor structure.
The “Intrinsic Value” of Cultural Heritage as Driver for Circular Human-Centered Adaptive Reuse

By referring to the European Green Deal, this paper analyzes the “intrinsic value” of cultural heritage by investigating the human-centered adaptive reuse of this heritage. This implies questions such as how to improve the effectiveness of reuse, restoration, and valorization interventions on cultural heritage/landscapes and how to transform a cultural asset into a place, interpreted as a living ecosystem, to be managed as a living organism. The autopoietic characteristic of the eco-bio-systems, specifically focusing on the intrinsic versus instrumental values of cultural heritage ecosystem is discussed in detail. Specifically, the notion of complex social value is introduced to express the above integration. In ecology, the notion of intrinsic value (or “primary value”) relates to the recognition of a value that “pre-exists” any exploitation by human beings. The effectiveness of transforming a heritage asset into a living ecosystem is seen to follow from an integration of these two values. In this context, the paper provides an overview of the different applications of the business model concept in the circular economy, for a better investment decision-making and management in heritage adaptive reuse. Matera case is presented as an example of a cultural heritage ecosystem. To conclude, recommendations toward an integrated approach in managing the adaptive reuse of heritage ecosystem as a living organism are proposed.
