description: This paper focuses on the impact of psychological wellbeing on the change perceived after a travel experience by young students. Wellbeing is investigated as a consequence and not as an antecedent of travel, though literature assumes the subjectivity of the travel experience. Expanding on existing literature, it is hypothesized that ‘change through travel’ is a three-dimensional concept: travellers may feel changed in their relationship with themselves, the other and the natural environment. In 2015 a survey was designed to explore the impact of wellbeing on change as a benefit from travel and a questionnaire administrated in a Dutch university. PCA confirmed the hypothesis and showed threedimensionality of change. Logistic regression models assessed the impact of wellbeing on change. Results suggest that four out of six wellbeing components (positive relations to others, autonomy, purpose in life, self-acceptance) influence the dimensions of change. Implications of these results for academics and professionals are discussed.

description: It is well known that there are resonant states with complex energy for the supercritical Coulomb impurity in graphene. We show that opening of a quasiparticle gap decreases the imaginary part of energy, |ImE|, of these states and stabilizes the system. For gapless quasiparticles with strong Coulomb interaction in graphene, we solve the Bethe-Salpeter equation for the electron - hole bound state and show that it has a tachyonic solution for strong enough coupling α=e^2/κ\hbar v_F leading to instability of the system. In the random-phase approximation, the critical coupling is estimated to be α_c =1.62 and is an analogue of the critical charge in the Coulomb center problem. We argue that the excitonic instability should be resolved through the formation of an excitonic condensate and gap generation in the quasiparticle spectrum.

description: Raman imaging on the edges of single layer micromechanical cleavage graphene (MCG) was carried out. The intensity of disorder-induced Raman feature (D band at ~1350 cm-1) was found to be correlated to the edge chirality: it is stronger at the armchair edge and weaker at the zigzag edge. This shows that Raman spectroscopy is a reliable and practical method to identify the chirality of graphene edge and to help in determination of the crystal orientation. The determination of graphene chirality is critically important for fundamental study as well as for applications.

description: It is well known that the twin boundary (TB) spacing plays an important role in controlling the strength of twinned metallic nanopillars. One of the reasons attributed to this strengthening behaviour is the force exerted by the TBs on dislocations. Since the TBs exert repulsive force on dislocations and the plasticity in nanopillars is surface controlled, it is interesting to know whether the TB position from the nanowire surface has any effect on the strength of twinned nanopillars. Using atomistic simulations, here we show that the TB position significantly influences the strength of twinned nanopillars. Atomistic simulations have been performed on nanopillar containing one and two TBs and their position is varied within nanopillar from the center to the surface. The results indicate that in nanopillar containing a single TB, the strength is maximum when the TB is located at the center of the nanopillar and it decreases as the TB is shifted towards the nanopillar surface. On the other hand in nanopillar containing two TBs, the maximum strength is observed when the twin boundaries are placed at distance of one fourth or one fifth the pillar size from the surfaces and it decreases when TBs are moved on either side. The present study demonstrates that the mechanical properties of the twinned nanopillars can be controlled by carefully tailoring the position of the TBs within the nanopillars.

description: The morphological evolution of voids at the unpassivated surfaces and the sidewalls of the single crystal metallic films are investigated via computer simulations by using the novel mathematical model developed by Ogurtani relying on the fundamental postulates of irreversible thermodynamics. The effects of the drift-diffusion anisotropy on the development of the surface morphological scenarios are fully explored under the action of the electromigration (EM) and capillary forces (CF), utilizing numerous combination of the surface textures and the directions of the applied electric field. The interconnect failure time due to the EM induced wedge shape internal voids and the incubation time of the oscillatory surface waves, under the severe instability regimes, are deduced by the novel renormalization procedures applied on the outputs of the computer simulation experiments.

description: Abstract

Transformational leadership is crucial for achieving project success in the UAE, a region characterized by rapid economic growth and cultural diversity, which adds complexity to project management. Leaders who embrace this style in the UAE power sector are known for inspiring and motivating their teams by cultivating a shared vision, encouraging innovation, and empowering team members to take ownership of their responsibilities. The UAE power sector is the second largest in the Middle East after Saudi Arabia, where projects are often large-scale and multifaceted; transformational leadership proves especially effective in project-based companies where organizational success depends on the successful completion of projects. By fostering an environment of trust, collaboration, and ongoing improvement, these leaders can navigate the challenges posed by the UAE's fast-paced and competitive market, ensuring that projects are delivered on schedule and within Budget and surpass expectations in quality and stakeholder satisfaction. This research was conducted to meet these objectives by employing an online survey via Google Forms between January 2024 and June 2024. The data from this response was processed quantitatively and analyzed by IBM SPSS. Correlation studies were conducted to find the significance of transformational leadership and five key project success factors. The study's findings indicated that transformational leadership in the UAE extends far beyond the successful delivery of projects by playing a pivotal role in stakeholder satisfaction and post-project benefit realization.
title: Nonstandard Employment and the Risk of Divorce in South Korea

description: Despite a persistent increase in South Korea’s divorce rate, our understanding of the economic determinants of divorce in South Korea is very limited. In particular, the relationship between nonstandard employment and divorce has received little attention, even though the number of nonstandard employees has rapidly increased in recent years. This paper examines the extent to which one’s employment type is associated with marital dissolution in South Korea, using nationally representative longitudinal data (the Korea Welfare Panel Study from 2007 to 2013). Results from discrete-time hazard models show that for men, the odds of divorce of nonstandard workers are estimated to be around 1.82 times the odds of standard employees. However, the risk of divorce for the self-employed is not statistically different from that of standard workers. In contrast, for women, employment type is not associated with divorce. These findings indicate that men’s employment quality and labor market status are still more important for marital stability than women’s in a context characterized by a strong male-breadwinner norm and rigid gender division of labor. This study contributes to the literature on economic determinants of marital dissolution by documenting gender differences in the relationship between various employment types and the risk of divorce in South Korea. Findings of this study will also have important implications for family policies in South Korea.

description: We present a calculation of the grand canonical partition function of a serial metallic island system by the imaginary-time path integral formalism. To this purpose, all electronic excitations in the lead and island electrodes are described using Grassmann numbers. Coulomb charging energy of the system is represented in terms of phase fields conjugate to the island charges. By the large channel approximation, the tunneling action phase dependence can also be determined explicitly. Therefore, we represent the partition function as a path integral over phase fields with a path probability given in an analytically known effective action functional. Using the result, we also propose a calculation of the average electron number of the serial island system in terms of the expectation value of winding numbers. Finally, as an example, we describe the Coulomb blockade effect in the two-island system by the average electron number and propose a method to construct the quantum stability diagram.

description: Infiltration of diffusing particles from one material to another where the diffusion mechanism is either normal or anomalous is a widely observed phenomena. When the diffusion is anomalous we find interesting behaviors: diffusion may lead to an averaged net drift from one material to another even if all particles eventually flow in the opposite direction, or may lead to a flow without drift. Starting with an underlying continuous time random walk model we solve diffusion equations describing this problem. Similar drift against flow is found in the quenched trap model. We argue that such a behavior is a general feature of diffusion in disordered systems.

description: This study analyses perceived risks in international tourism and looks at how several key indicators contribute to the individuals’ perception of risk in international travel. The purpose of this article is twofold: firstly, to explore the primary risk dimensions associated with international travel; and secondly, to investigate whether sociodemographic variables and past travel experience influence perceived risks. To achieve these purposes, a scale of perceived risks was previously tested using a sample of 530 respondents. An exploratory factor analysis was conducted and a scale of five factors of perceived risks towards travelling internationally was obtained, namely: physical risk, destination risk, value-time risk, personal concerns and inconveniences. This study also revealed that perceptions of risk involved while travelling internationally vary according to personal characteristics, such as gender, age and level of education, as well as past travel experience. Theoretical and practical implications are also discussed.

description: The CL/P are the most common and easily recognizable craniofacial malformations with a complex etiology that  requires the involvement of genetic and environmental components.
The analysis of the genetic component shows more than 14 loci and genes  involved in the onset of the disease.
I’ve selected and investigated some of the possible candidate genes for CL/P.
MYH14 gene, that maps on chromosome 19, on the OFC3 locus, and shows a strong homology with MYH9 gene. 
I’ve also investigated TP63 and MID1 genes, that are responsible respectively for EEC syndrome and Opitz syndrome, both of them presenting cleft. I’ve also decided to investigate JAG2 because TP63 product regulates the this gene, and both of them are component of the Notch signalling pathway.
I’ve, also,  studied the MKX and LMO4 genes. MKX is an important development regulator that is highly expressed in palatal mesenchyme, and map in the region responsible for Twirler mutation that  cause  cleft in mouse.
LMO4 is necessary for neural tube development and cooperating with Grhl3, promotes cellular  migration during morphogenetic events like “in utero” cleft healing. 
Low folate levels and high levels of homocysteine  increase the risk of cleft, genes involved in their metabolism may be of interest in cleft occurrence. I’ve decided to investigate BHMT and CBS genes  coding for enzymes involved in homocysteine metabolism. I’ve also investigated BHMT2 gene that maps close to BHMT and presents with him  a 73% of homology.
I’ve performed a linkage analysis using SNPs mapping  in the genes and their boundaries, for each gene, for MKX and LMO4 I’ve also performed a sequencing analysis. 
My results for MID1 and CBS genes support the hypothesis of a possible role of these genes in cleft.
I’ve found borderline association values for JAG2, MKX and LMO4 genes.

description: Preserving functional health and quality-of-life in old age is a major goal and global challenge in public health. The high rate of sedentary behavior that is characteristic of the older adult population exacerbates impairments of physiological and structural systems that are typically seen in the aging process. Achieving an understanding of the profound influence of physical activity on all aspects of health in old age is the driving force behind the emergence of "physical activity in old age" as a growing area of research. Accumulated evidence implies that being physically active and exercising is far superior to other optimal aging facilitators. Yet this area of research faces numerous constraints and obstacles. This commentary addresses some of these challenges, primarily the heterogeneity of the aging process, which induces both inter- and intra-individual differences among aged individuals, heterogeneity in assessment tools, unjustified inclusion/exclusion criteria and insufficient recruitment strategies, difficulties in implementing research results in real-world conditions, and rudimentary exploitation of innovative technology. We explain the importance of establishing a network of multidisciplinary scientists and stakeholders to propose consensus-based goals and scientifically evidenced wide-ranging plans for dealing with these challenges. In addition, we suggest work directions for this network.

description: We theoretically analyzed inelastic effects in the electron transport through molecular junctions originating from electron-vibron interactions. The molecular bridge was simulated by a periodic chain of identical interacting hydrogen-like atoms providing a set of energy states for the electron tunneling. To avoid difficulties inevitably arising when advanced computational techniques are employed to study inelastic electron transport through multilevel bridges, we propose and develop a semiphenomenological approach. The latter is based on the Buttiker's dephasing model within the scattering matrix formalism. The advantage of the proposed approach is that it allows to analytically study various inelastic effects on the conduction through molecular junctions including multilevel bridges. Here, we apply this approach to describe features associated with electron energy transfer to vibrational phonons which appear in the inelastic tunneling spectra of electrons. In the particular case of a single level bridge our results agree with those obtained by self-consitent calculations carried out within the nonequilibrium Green's functions method validating the usefulness of the suggested approach.

description: Purpose: to quantify the mRNA levels of MMP-3, MMP-9, VEGF and Survivin in peripheral blood and the serum levels of CA-125, Ca19-9 in women with and without endometriosis and to investigate the performance of these markers to differentiate between deep and ovarian endometriosis.
Methods: a case controls study enrolled a series of 60 patients. Twenty controls have been matched with 20 cases of ovarian and 20 cases of deep endometriosis. Univariable and multivariable performance of serum CA125 and CA19-9, mRNA for Survivin, MMP9, MMP3 and VEGF genes have been evaluated by means of ROC curves and logistic regression respectively. 
Results: No difference in markers concentration were detected between ovarian and deep endometriosis. In comparison with controls serum CA19 and CA125 yielded the better sensitivity followed by mRNA for Survivin gene (81.5%, 51.9% and 7.5% at 10% false positive rate respectively).  Multivariable estimated odds of endometriosis yielded a sensitivity of 87% at the same false positive rate.
Conclusions: A combination of serum and molecular markers could allow a better diagnosis of endometriosis.

description: We examine the practical feasibility of the experimental realization of the so-called entangled Bose-Einstein condensation (BEC), occurring in an entangled state of two atoms of different species. We demonstrate that if the energy gap remains vanishing, the entangled BEC persists as the ground state of the concerned model in a wide parameter regime. We establish the experimental accessibility of the isotropic point of the effective parameters, in which the entangled BEC is the exact ground state, as well as the consistency with the generalized Gross-Pitaevskii equations. The transition temperature is estimated. Possible experimental implementations are discussed in detail.

description: This paper examined the relationship among tourism, terrorism and broad economic aggregates. We made use of the impulse response and variance decomposition of the Vector Autoregression (VAR) on the Nigerian economy from 1995Q1 to 2012Q4. Besides the appropriate unit root and cointegration properties of the variables, the result revealed, that terrorism had negative effects on other variables of the study, especially tourism. Also, shocks in other variables are majorly caused by terrorism. The study also revealed that tourism responds positively to FDI, but its response to GDP and FDI are mixed overtime. Therefore, growth-promoting and other complimentary policies that will engender aggregate welfare improvement need to be pursued to ensure that the tourism sector sidestep the adverse consequences of terrorism.

Oltre ad un’analisi dei singoli passi degli autori citati al termine di ogni città o altro luogo geografico indicato si trova una scheda riassuntiva in cui si fa il punto dei dati che derivano dalle fonti citate, per vedere in che cosa esse sono utili per tracciare un quadro complessivo dell’abitato nell’epoca antica. Naturalmente, per procedere ad un lavoro di questo genere, si fa un costante confronto con gli altri tipi di fonti presenti, in gran parte quelle archeologiche ed epigrafiche, necessarie per la storia sociale ed istituzionale delle località in questione.  Laddove i  toponimi non indichino città, ma altri luoghi piuttosto si dedica spazio alla localizzazione geografica in situazione spesso di contraddizione tra la dottrina, non sempre recente ed aggiornata con le ultime scoperte epigrafiche, in particolare di cippi confinari. 
Scopo finale della tesi è appunto quello di verificare luogo per luogo quali progressi possano essere fatti, per definire in modo preciso da un lato la geografia fisica della regione e dall’altro la storia istituzionale e la Romanizzazione dei centri, che non fu uniforme ed organica.

description: The extraction of meson-baryon scattering parameters from lattice QCD is complicated by the necessity, in some channels, of including annihilation diagrams. We consider a strategy to avoid the need for these extremely costly and noisy contributions. The strategy is based on simulations with an isospin chemical potential which, contrary to a baryon chemical potential, has no sign problem. When the isospin chemical potential is larger than a critical value, a charged pion condensate forms. Baryons propagating in the pion condensate will have their masses modified by pion-baryon scattering parameters. Consequently these parameters can be extracted from lattice QCD simulations in an isospin chemical potential, and we detail precisely which low-energy constants using baryon chiral perturbation theory.

description: The primary aim of this dissertation to identify subgroups of patients with chronic kidney disease (CKD) who have a differential risk of progression of illness and the secondary aim is compare 2 equations to estimate the glomerular filtration rate (GFR). To this purpose, the PIRP (Prevention of Progressive Kidney Disease) registry was linked with the dialysis and mortality registries. The outcome of interest is the mean annual variation of GFR, estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. A decision tree model was used to subtype CKD patients, based on the non-parametric procedure CHAID (Chi-squared Automatic Interaction Detector). The independent variables of the model include gender, age, diabetes, hypertension, cardiac diseases, body mass index, baseline serum creatinine, haemoglobin, proteinuria, LDL cholesterol, tryglycerides, serum phoshates, glycemia, parathyroid hormone and uricemia. The decision tree model classified patients into 10 terminal nodes using 6 variables (gender, age, proteinuria, diabetes, serum phosphates and ischemic cardiac disease) that predict a differential progression of kidney disease. Specifically, age <=53 year, male gender, proteinuria, diabetes and serum phosphates >3.70 mg/dl predict a faster decrease of GFR, while ischemic cardiac disease predicts a slower decrease. The comparison between GFR estimates obtained using MDRD4 and CKD-EPI equations shows a high percentage agreement (>90%), with modest discrepancies for high and low age  and serum creatinine levels. The study results underscore the need for a tight follow-up schedule in patients with age <53, and of patients aged 54 to 67 with diabetes, to try to slow down the progression of the disease. The result also emphasize the effective management of patients aged>67, in whom the estimated decrease in glomerular filtration rate corresponds with the physiological decrease observed in the absence of kidney disease, except for the subgroup of patients with proteinuria, in whom the GFR decline is more pronounced.

description: This study focuses on quantification of economic impacts of tourism by measuring tourism expenditure at the national level via input-output tables which are transmitted to The European System of National and Regional Accounts (ESA 2010) and current Tourism Satellite Account (TSA) based on 2013-14 financial year data. The key findings are as follows: In the year 2013 it accounted for the sum of EUR 4.624.912 thousand. A basic parameter for its calculation is a multiplier of value added with induced effect in the amount of 1.1938. It was the production of selected foods and tobacco, production of accommodation services and catering services that contributed to the total economic value of tourism in the highest volume. Practical utilisations of results consist in creating a database performing more effective decision making process.

description: Evolution of the nonequilibrium thermodynamic entities corresponding to dynamics of the Hopf instabilities and traveling waves at a nonequilibrium steady state of a spatially extended glycolysis model is assessed here by implementing an analytically tractable scheme incorporating a complex Ginzburg-Landau equation (CGLE). In the presence of self and cross diffusion, a more general amplitude equation exploiting the multiscale Krylov-Bogoliubov averaging method serves as an essential tool to reveal the various dynamical instability criteria, especially Benjamin-Feir (BF) instability, to estimate the corresponding nonlinear dispersion relation of the traveling wave pattern. The critical control parameter, wave-number selection criteria, and magnitude of the complex amplitude for traveling waves are modified by self- and cross-diffusion coefficients within the oscillatory regime, and their variabilities are exhibited against the amplitude equation. Unlike the traveling waves, a low-amplitude broad region appears for the Hopf instability in the concentration dynamics as the system phase passes through minima during its variation with the control parameter. The total entropy production rate of the uniform Hopf oscillation and glycolysis wave not only qualitatively reflects the global dynamics of concentrations of intermediate species but almost quantitatively. Despite the crucial role of diffusion in generating and shaping the traveling waves, the diffusive part of the entropy production rate has a negligible contribution to the system's total entropy production rate. The Hopf instability shows a more complex and colossal change in the energy profile of the open nonlinear system than in the traveling waves. A detailed analysis of BF instability shows a contrary nature of the semigrand Gibbs free energy with discrete and continuous wave numbers for the traveling wave.

description: Tourist satisfaction is the most important component in the analysis of tourism behavior, since it affects the choice of destination and the purchase of products, as well as the potential decision of the tourist to revisit the destination. The purpose of this paper is to examine the satisfaction of tourists visiting the Ionian Islands in Greece, by use of quantitative methods that capture the factors influencing the satisfaction of tourists and their desire to repeat the visit, their relationship and consideration of the causes that shape tourism behavior. Research results reveal factors that affect tourist satisfaction, the relationships among these factors, the relationship between satisfaction and revisit to destination, the assessment of satisfaction by segmentation of tourists with regard to their motivation, the usability of information in satisfaction and the effect of tourism experience in travel behavior. The tourism policy recommendations arising from the research results will contribute to the diversification and enrichment of the tourism product, while also to a further enhancement in the satisfaction of tourists visiting the Ionian Islands.

description: An optimized molecular model for ammonia, which is based on a previous work of Kristoef et al., Mol. Phys. 97 (1999) 1129--1137, is presented. Improvements are achieved by including data on geometry and electrostatics from quantum mechanical calculations in a first model. Afterwards the parameters of the Lennard-Jones potential, modeling dispersive and repulsive interactions, are optimized to experimental vapor-liquid equilibrium data of pure ammonia. The resulting molecular model shows mean unsigned deviations to experiment of 0.7% in saturated liquid density, 1.6% in vapor pressure, and 2.7% in enthalpy of vaporization over the whole temperature range from triple point to critical point. This new molecular model is used to predict thermophysical properties in the liquid, vapor and supercritical region, which are in excellent agreement with a high precision equation of state, that was optimized to 1147 experimental data sets. Furthermore, it is also capable to predict the radial distribution functions properly, while no structural information is used in the optimization procedure.
title: Residents' attitudes toward tourism development and its impacts (case: Montenegro)

description: Residents’ attitudes toward tourism development and its impacts (economic, sociocultural and environmental) in case of Montenegro haven’t been analyzed before in a scientific and systematic way. The main aim of this paper is to provide a highquality base for further research bearing in mind that there is no relevant, scientific research related to this topic. For the purposes of this paper poll survey among residents in Montenegro (total 857) was conducted in 2018. Collected data were processed and analyzed by different statistical methods. Results showed that attitudes of residents depend on their place of residence. There is also a statistically significant relationship between demographic characteristics and positive and negative attitudes toward tourism impacts but the relationship is not strong. New, expanded research regarding the topic is recommended as well as the introduction of destination lifecycle analysi.

description: We describe the preparation of atom-number states with strongly interacting bosons in one dimension, or spin-polarized fermions. The procedure is based on a combination of weakening and squeezing of the trapping potential. For the resulting state, the full atom number distribution is obtained. Starting with an unknown number of particles $N_i$, we optimize the sudden change in the trapping potential which leads to the Fock state of $N_f$ particles in the final trap. Non-zero temperature effects as well as different smooth trapping potentials are analyzed. A simple criterion is provided to ensure the robust preparation of the Fock state for physically realistic traps.

description: Motivated by recent experiments on rotating Bose-Einstein condensates, we investigate a rotating, polarized Fermi gas trapped in an anharmonic potential. We apply a semiclassical expansion of the density of states in order to determine how the thermodynamic properties depend on the rotation frequency. The accuracy of the semiclassical approximation is tested and shown to be sufficient for describing typical experiments. At zero temperature, rotating the gas above a given frequency $Ω_{\rm DO}$ leads to a `donut'-shaped cloud which is analogous to the hole found in two-dimensional Bose-Einstein condensates. The free expansion of the gas after suddenly turning off the trap is considered and characterized by the time and rotation frequency dependence of the aspect ratio. Temperature effects are also taken into account and both low- and high-temperature expansions are presented for the relevant thermodynamical quantities. In the high-temperature regime a virial theorem approach is used to study the delicate interplay between rotation and anharmonicity.

description: We report a robust method of stabilizing a laser to the frequency of an atomic transition using a hollow cathode lamp. In contrast to the standard dichroic atomic vapor laser lock (DAVLL) method, which uses dichroism induced by a longitudinal magnetic field, we employ birefringence induced by a transversal magnetic field. We applied this method to the $(5s^2)\ {}^{1}S_{0} - (5s5p)\ {}^{1}P_{1}$ transition (461 nm) of Sr. Although the hollow cathode is made of ferromagnetic material, we successfully applied a magnetic field of sufficient strength to obtain an error signal with a theoretical maximum slope. This method may be applied to other hollow cathode lamps of different atomic species.

Catching Unusual Traffic Behavior using TF-IDF-based Port Access Statistics Analysis

description: Detecting the anomalous behavior of traffic is one of the important actions for network operators. In this study, we applied term frequency - inverse document frequency (TF-IDF), which is a popular method used in natural language processing, to detect unusual behavior from network access logs. We mapped the term and document concept to the port number and daily access history, respectively, and calculated the TF-IDF. With this approach, we could obtain ports frequently observed in fewer days compared to other port access activities. Such access behaviors are not always malicious activities; however, such information is a good indicator for starting a deeper analysis of traffic behavior. Using a real-life dataset, we could detect two bot-oriented accesses and one unique UDP traffic.

description: The recent discovery of superconducting interfaces in the $KTaO_3 (111)$-based heterostructures is intriguing, since a much higher superconducting critical temperature (TC ~ 2 K) is achieved compared to that in the $SrTiO_3$ heterostructures (~ 300 mK). In this paper, we report the superconducting properties of $EuO/KTaO_3 (111)$ interface as a function of the interface carrier density ($n_s$). The maximum T_C is observed to be ~ 2 K at $n_s$ ~ $1\times10^{14}$ cm-2. In addition, we show that the critical current density and the upper critical magnetic field can be effectively tuned by the back gate voltage. Interestingly, the gate dependence of the upper critical magnetic field exhibits a trend opposite to that of TC in the underdoped region, suggesting a relatively larger Cooper pairing potential.
