description: Lucrarea de față, explorează peisajul urban al Focșaniului prin combinarea unei analize obiective a principalelor elemente urbane cu percepția rezidenților. Studiul subliniază semnificația calității peisajului urban în asigurarea unui oraș sustenabil și funcțional, în special în contextul tendințelor globale de urbanizare, unde peste 55% din populația lumii trăiește în zone urbane, un procent care se estimează că va ajunge la 68% până în 2050.  Cercetarea utilizează o metodologie complexă, incluzând fișe de observații pentru evaluarea mediului fizic, sondaje pentru captarea percepției rezidenților și analiza rețelei de actori pentru evaluarea rolurilor și responsabilităților actorilor urbani cheie. Evaluarea se concentrează pe cinci componente majore: infrastructura rutieră, clădirile rezidențiale, spațiile verzi, clădirile cu valoare culturală și zona industrială. Fiecare element este analizat pe baza unor criterii structurate, utilizând o scală Likert de cinci puncte pentru a asigura consistență și obiectivitate în colectarea datelor.  Rezultatele arată că Focșaniul este într-un proces de transformare urbană, dar se confruntă cu provocări semnificative. De exemplu, districtul Sud dispune de o infrastructură relativ bună, în timp ce ANL Democrați și Obor necesită îmbunătățiri semnificative în ceea ce privește calitatea drumurilor, iluminatul stradal și serviciile publice. Spațiile verzi variază ca și calitate a întreținerii, parcurile recent renovate obținând scoruri mai mari, în timp ce parcurile mai vechi, precum Parcul Teatrului și Robert Schuman, suferă de pe urma neglijenței. Zonele industriale prezintă contrasturi clare, unele fiind bine întreținute și funcționale, în timp ce altele sunt abandonate și deteriorate, afectând negativ peisajul urban.  Analiza rețelei de actori arată că rezidenții percep autoritățile locale ca fiind principalele responsabile de gestionarea urbană, inclusiv de eliminarea deșeurilor, întreținerea infrastructurii și îngrijirea spațiilor verzi. Studiul sugerează intervenții cheie, precum extinderea spațiilor verzi urbane, restaurarea patrimoniului cultural, modernizarea infrastructurii publice și promovarea investițiilor

description: The dried flower buds of Magnolia biondii Pamp (herbal name, Xin-Yi) are a traditional Chinese medicine with a long history of clinical use in the treatment of allergic rhinitis and sinusitis. However, the constituents responsible for its antiallergic effects remain clearly unidentified. In the present study, totally 33 lignans were obtained from M. biondii. Among them, two novel furofuran lignans (1 and 2), two novel tetrahydrofuran lignans (3 and 4), and other 16 known lignans were isolated first time from M. biondii. The antiallergic effects of compounds 1-33 on mouse bone marrow-derived mast cells (BMMCs) degrunaliton were evaluated and results showed that compounds 7, 8, 13, 15 and 18 could significantly inhibited β-hex release on BMMCs. The results proved that furofuran and tetrahydrofuran lignans were the main constituents in M. biondii and their antiallergic effects were related with suppressing mast cell activation.

description: The mesosphere and lower thermosphere (MLT) region is dominated globally by dynamics at various scales: planetary waves, tides, gravity waves, and stratified turbulence. The latter two can coexist and be significant at horizontal scales less than 500 km, scales that are difficult to measure. This study presents a recently deployed multistatic specular meteor radar system, SIMONe Peru, which can be used to observe these scales. The radars are positioned at and around the Jicamarca Radio Observatory, which is located at the magnetic equator. Besides presenting preliminary results of typically reported large-scale features, like the dominant diurnal tide at low latitudes, we show results on selected days of spatially and temporally resolved winds obtained with two methods based on: (a) estimation of mean wind and their gradients (gradient method), and (b) an inverse theory with Tikhonov regularization (regularized wind field inversion method). The gradient method allows improved MLT vertical velocities and, for the first time, low-latitude wind field parameters such as horizontal divergence and relative vorticity. The regularized wind field inversion method allows the estimation of spatial structure within the observed area and has the potential to outperform the gradient method, in particular when more detections are available or when fine adaptive tuning of the regularization factor is done. SIMONe Peru adds important information at low latitudes to currently scarce MLT continuous observing capabilities. Results contribute to studies of the MLT dynamics at different scales inherently connected to lower atmospheric forcing and E-region dynamo related ionospheric variability.

description: We investigate higher spin AdS$_{3}$ gravity with real split forms of complex A$_{N}$ B$_{N}$, C$_{N}$ and D$_{N}$ Lie algebras. This is done by linking $SO(1,2)$ spin multiplets with splitted root systems using Tits-Satake diagrams of real forms. Unlike $SL(N,R)$, we show that the orthogonal families have two different higher spin (HS) spectrums: vectorial and spinorial. We find amongst others that the spinorial spectrum has an isolated spin j$_{\mathcal{N}}$ given by $\mathcal{N}\left(\mathcal{N}+1\right)/2$ for $SO(\mathcal{N},1+\mathcal{N})$ and $\mathcal{N} \left( \mathcal{N}-1\right) /2$ for $SO(\mathcal{N},\mathcal{N})$. We implement these results into the computation of the HS partition functions in these gravity theories and identify the individual contributions of the higher spin fields; valuable to manoeuver the HS-BTZ black hole partition function

description: Recently, many results on the computational complexity of sorting algorithms were obtained using Kolmogorov complexity (the incompressibility method). Especially, the usually hard average-case analysis is ammenable to this method. Here we survey such results about Bubblesort, Heapsort, Shellsort, Dobosiewicz-sort, Shakersort, and sorting with stacks and queues in sequential or parallel mode. Especially in the case of Shellsort the uses of Kolmogorov complexity surprisingly easily resolved problems that had stayed open for a long time despite strenuous attacks.

description: This study explored how a scenario-based (SB), one-semester professional development program influenced the instructional practices of preservice early childhood mathematics teachers. The participants completed a 15-week program in which they engaged with modeled in-class teaching experience and subsequently answered a number of questions that prompted them to consider possible ways of reacting in similar, everyday interactions with children. The findings indicate that the SB activities enhanced the teachers’ perceived instructional practices and their motivation to use student-centered instruction when teaching early mathematical concepts to children. By contrast, results indicate that the preservice teachers developed lower scores on the teacher-centered practices construct after their engagement in the SB professional program. This research inspired the recommendation that early childhood teachers should find balance in focusing on direct math content with supporting children’s self-efficacy and emotional development through child-centered instruction.

description: We present a surface trap which allows for studying the coherent interaction of ultracold atoms with evanescent waves. The trap combines a magnetic Joffe trap with a repulsive evanescent dipole potential. The position of the magnetic trap can be controlled with high precision which makes it possible to move ultracold atoms to the surface of a glass prism in a controlled way. The optical potential of the evanescent wave compensates for the strong attractive van der Waals forces and generates a potential barrier at only a few hundred nanometers from the surface. The trap is tested with Rb Bose-Einstein condensates (BEC), which are stably positioned at distances from the surfaces below one micrometer.

description: On a grassland field with sandy soils in Northeast Germany (Brandenburg), vegetation indices from multi-spectral UAV-based remote sensing were used to predict grassland biomass productivity. These data were combined with soil pH value and apparent electrical conductivity (ECa) from on-the-go proximal sensing serving as indicators for soil-borne causes of grassland biomass variation. The field internal magnitude of spatial variability and hidden correlations between the variables of investigation were analyzed by means of geostatistics and boundary-line analysis to elucidate the influence of soil pH and ECa on the spatial distribution of biomass. Biomass and pH showed high spatial variability, which necessitates high resolution data acquisition of soil and plant properties. Moreover, boundary-line analysis showed grassland biomass maxima at pH values between 5.3 and 7.2 and ECa values between 3.5 and 17.5 mS m−1. After calibrating ECa to soil moisture, the ECa optimum was translated to a range of optimum soil moisture from 7% to 13%. This matches well with to the plant-available water content of the predominantly sandy soil as derived from its water retention curve. These results can be used in site-specific management decisions to improve grassland biomass productivity in low-yield regions of the field due to soil acidity or texture-related water scarcity.
INVESTIGAȚII GEOMORFOLOGICE ASUPRA GROHOTIȘURILOR SUPRARĂCITE GRANITICE DE PE VALEA JIEȚULUI DIN MUNȚII PARÂNG

description: Grohotisurile suprarăcite sunt forme de relief periglaciar, situate la alitudini de sub 2000 m, care prezintă particularitatea de a adăposti permafrost de altitudine joasă. Mecansimul care le conferă caracterul de "suprarăcite" este efectul de șemineu, reprezentat de o circulație sezonală a aerului în interiorul grohotișurilor. Aceste forme de relief sunt intens studiate la scară europeană, cu precădere în Alpii Francezi, unde a și fost observat fenomenul pentru prima oară. Grohotișurile de pe Valea Jiețului din Munții Parâng au fost studiate cu scopul de a demonstra existența altor situri potențiale care ar găzdui permafrost pe teritoriul României, pe lângă cel de la Detundata Goală. Studiul prezintă o importanță semnificativă deoarece cercetările asupra grohotișurilor suprarăcite din Carpați sunt puțin numeroase, fiind astfel posibilă contribuirea la domeniul de cercetare prin introducerea unui nou astfel de sit. În ceea ce privește metodologia, pentru identificarea posibilelor anomalii termice au fost utilizați senzori de temperatură montați în interiorul grohotișurilor, cât și în exteriorul acestora, rezultatul demonstrând o diferență de până la 3 grade Celsius între temperatura aerului din interiorul grohotișurilor și cel din exterior. Pentru măsurarea vitezei curentului ce caracterizează efectul de șemineu, s-a folosit un anemometru montat în interiorul grohotișului care a identificat perioade cu circulație mai intensă. Pentru monitorizarea circulației efectului de șemineu au mai fost efectuate zboruri cu drona termală care au arătat zonele de evacuare ale aerului mai cald. Măsurătorile geofizice prin intermediul ERT au confirmat prezența unor zone cu rezistivitate electrică mare, valorile fiind comparabile cu acelea găsite la situri din Munții Alpi, unde a fost confirmată prezența permafrostului.

Prin urmare, concluziile studiului susțin un posibil nou sit pe teritoriul țării  care ar putea găzdui permafrost de altitudine joasă, lucru ce implică viitoare cercetări și pentru confirmarea permafrostului în cadrul sitului.

description: Poor academic performance is known to be linked to the tendency to procrastinate. The latter is thought to reflect deficits in effort regulation and study time management (i.e. learning-related resources), but some recent results have suggested that it could stem from psychological inflexibility. The main objective of the present study was thus to ascertain whether effort regulation, study time management, and psychological (in)flexibility predict variations in French students’ academic procrastination. The results of an online survey among 259 first-year humanities and social sciences students revealed that 42.4% of the variance in procrastination was predicted by effort regulation and study time management, and 4% by psychological inflexibility. There was also a negative relationship between academic performance and procrastination. These results are discussed in terms of the usefulness of implementing interventions at the start of university to promote academic success and student wellbeing.

description: Tensors are used to describe complex physical processes in many applications. Examples include the distribution of stresses in technical materials, acting forces during seismic events, or remodeling of biological tissues. While tensors encode such complex information mathematically precisely, the semantic interpretation of a tensor is challenging. Visualization can be beneficial here and is frequently used by domain experts. Typical strategies include the use of glyphs, color plots, lines, and isosurfaces. However, data complexity is nowadays accompanied by the sheer amount of data produced by large-scale simulations and adds another level of obstruction between user and data. Given the limitations of traditional methods, and the extra cognitive effort of simple methods, more advanced tensor field visualization approaches have been the focus of this work. This survey aims to provide an overview of recent research results with a strong application-oriented focus, targeting applications based on continuum mechanics, namely the fields of structural, bio-, and geomechanics. As such, the survey is complementing and extending previously published surveys. Its utility is twofold: (i) It serves as basis for the visualization community to get an overview of recent visualization techniques. (ii) It emphasizes and explains the necessity for further research for visualizations in this context.

description: We report a development of a new fast surface-based method for numerical calculations of solvation energy of biomolecules with a large number of charged groups. The procedure scales linearly with the system size both in time and memory requirements, is only a few percent wrong for any molecular configurations of arbitrary sizes, gives explicit value for the reaction field potential at any point, provides both the solvation energy and its derivatives suitable for Molecular Dynamics simulations. The method works well both for large and small molecules and thus gives stable energy differences for quantities such as solvation energies of molecular complex formation.

description: In this paper we consider the effect of self-localization of a quantum impurity in Bose-Einstein condensate. Space correlation function of the impurity is evaluated with the help of the imaginary-time path integral approach. Employing the Feynman's variational method we calculate the impurity correlation function as well as the energy of the system associated with the impurity. The effect of self-localization predicted before within Gross-Pitaevskii approach is recovered by our treatment. The strong coupling regime with negative ground state energy is reached by variational method, and corresponding correlation function is calculated.

description: Ultrafast supercontinuum generation crucially depends on the dispersive properties of the underlying waveguide. This strong dependency allows for tailoring nonlinear frequency conversion and is particularly relevant in the context of waveguides that include geometry-induced resonances. Here, we experimentally uncovered the impact of the relative spectral distance between the pump and the bandgap edge on the supercontinuum generation and in particular on the dispersive wave formation on the example of a liquid strand-based photonic bandgap fiber. In contrast to its air-hole-based counterpart, a bandgap fiber shows a dispersion landscape that varies greatly with wavelength. Particularly due to the strong dispersion variation close to the bandgap edges, nanometer adjustments of the pump wavelength result in a dramatic change of the dispersive wave generation (wavelength and threshold). Phase-matching considerations confirm these observations, additionally revealing the relevance of third order dispersion for interband energy transfer. The present study provides additional insights into the nonlinear frequency conversion of resonance-enhanced waveguide systems which will be relevant for both understanding nonlinear processes as well as for tailoring the spectral output of nonlinear fiber sources.

description: This study employed a concurrent embedded design to compare the accounting curricula of selected universities in Africa, America, Asia, and Europe, guided by International Education Standards (IES) 2, 3, 4, and 5. Fourteen universities from different continents were conveniently selected, and a descriptive content analysis was conducted to analyse the undergraduate accounting program contents. The findings reveal that the accounting education in selected African universities aligns with IES 2, 3, 4 and other universities, countering claims of inferiority. However, the universities’ curricula in Africa lack practical job-related competencies (IES 5) due to limited opportunities for experiential learning. Disparities exist in the emphasis on IES competencies, potentially leading to imbalanced development among graduates. African universities prioritise employment-oriented education, while those in America, Asia, and Europe emphasise professional progression. Recommendations include enhancing ethics and professional values, allocating more curriculum space for ethical behaviour promotion, and creating room for practical skills acquisition to facilitate students’ application of learned concepts and facilitate potential remediation.
The Neptune Trojans - a new source for the Centaurs?

Year: 2010
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The fact that the Centaurs are the primary source of the Short Period Comets is well established. However, the origin of the Centaurs themselves is still under some debate, with a variety of different source reservoirs being proposed in the last decade. In this work, we suggest that the Neptune Trojans (together with the Jovian Trojans) could represent an additional significant source of Centaurs. Using dynamical simulations of the first Neptune Trojan discovered (2001 QR322), together with integrations following the evolution of clouds of theoretical Neptune Trojans obtained during simulations of planetary migration, we show that the Neptune Trojan population contains a great number of objects which are unstable on both Myr and Gyr timescales. Using individual examples, we show how objects that leave the Neptunian Trojan cloud evolve onto orbits indistinguishable from those of the known Centaurs, before providing a range of estimates of the flux from this region to the Centaur population. With only moderate assumptions, it is shown that the Trojans can contribute a significant proportion of the Centaur population, and may even be the dominant source reservoir. This result is supported by past work on the colours of the Trojans and the Centaurs, but it will take future observations to determine the full scale of the contribution of the escaped Trojans to the Centaur population.

description: Cellulases are industrially important enzymes, e.g., in the production of bioethanol, in pulp and paper industry, feedstock, and textile. Thermostability is often a prerequisite for high process stability and improving thermostability without affecting specific activities at lower temperatures is challenging and often time-consuming. Protein engineering strategies that combine experimental and computational are emerging in order to reduce experimental screening efforts and speed up enzyme engineering campaigns. Constraint Network Analysis (CNA) is a promising computational method that identifies beneficial positions in enzymes to improve thermostability. In this study, we compare CNA and directed evolution in the identification of beneficial positions in order to evaluate the potential of CNA in protein engineering campaigns (e.g., in the identification phase of KnowVolution). We engineered the industrially relevant endoglucanase EGLII from Penicillium verruculosum towards increased thermostability. From the CNA approach, six variants were obtained with an up to 2-fold improvement in thermostability. The overall experimental burden was reduced to 40% utilizing the CNA method in comparison to directed evolution. On a variant level, the success rate was similar for both strategies, with 0.27% and 0.18% improved variants in the epPCR and CNA-guided library, respectively. In essence, CNA is an effective method for identification of positions that improve thermostability.

description: In this paper the question about statistical properties of block--hierarchical random matrices is raised for the first time in connection with structural characteristics of random hierarchical networks obtained by mipmapping procedure. In particular, we compute numerically the spectral density of large random adjacency matrices defined by a hierarchy of the Bernoulli distributions $\{q_1,q_2,...\}$ on matrix elements, where $q_γ$ depends on hierarchy level $γ$ as $q_γ=p^{-μγ}$ ($μ>0$). For the spectral density we clearly see the free--scale behavior. We show also that for the Gaussian distributions on matrix elements with zero mean and variances $σ_γ=p^{-νγ}$, the tail of the spectral density, $ρ_G(λ)$, behaves as $ρ_G(λ) \sim |λ|^{-(2-ν)/(1-ν)}$ for $|λ|\to\infty$ and $0

description: Ionic liquids (IL) and aqueous ionic liquids (aIL) are attractive (co-)solvents for biocatalysis due to their unique properties. On the other hand, the incubation of enzymes in IL or aIL often reduces enzyme activity. Recent studies proposed various aIL-induced effects to explain the reduction, classified as direct effects, e.g., local dehydration or competitive inhibition, and indirect effects, e.g., structural perturbations or disturbed catalytic site integrity. However, the molecular origin of indirect effects has largely remained elusive. Here we show by multi-μs long molecular dynamics simulations, free energy computations, and rigidity analyses that aIL favorably interact with specific residues of Bacillus subtilis Lipase A (BsLipA) and modify the local structural stability of this model enzyme by inducing long-range perturbations of noncovalent interactions. The perturbations percolate over neighboring residues and eventually affect the catalytic site and the buried protein core. Validation against a complete experimental site saturation mutagenesis library of BsLipA (3620 variants) reveals that the residues of the perturbation pathways are distinguished sequence positions where substitutions highly likely yield significantly improved residual activity. Our results demonstrate that identifying these perturbation pathways and specific IL ion-residue interactions there effectively predicts focused variant libraries with improved aIL tolerance.

description: We construct global F-theory GUT models on del Pezzo surfaces in compact Calabi-Yau fourfolds realized as complete intersections of two hypersurface constraints. The intersections of the GUT brane and the flavour branes as well as the gauge flux are described by the spectral cover construction. We consider a split S[U(4) x U(1)_X] spectral cover, which allows for the phenomenologically relevant Yukawa couplings and GUT breaking to the MSSM via hypercharge flux while preventing dimension-4 proton decay. General expressions for the massless spectrum, consistency conditions and a new method for the computation of curvature-induced tadpoles are presented. We also provide a geometric toolkit for further model searches in the framework of toric geometry. Finally, an explicit global model with three chiral generations and all required Yukawa couplings is defined on a Calabi-Yau fourfold which is fibered over the del Pezzo transition of the Fano threefold P^4[4].

description: In this work, we investigate the dynamical stability of pre-formed Neptune Trojans under the gravitational influence of the four giant planets in compact planetary architectures, over 10 Myr. In our modelling, the initial orbital locations of Uranus and Neptune (aN) were varied to produce systems in which those planets moved on non-resonant orbits, or in which they lay in their mutual 1:2, 2:3 and 3:4 mean-motion resonances (MMRs). In total, 420 simulations were carried out, examining 42 different architectures, with a total of 840000 particles across all runs. In the non-resonant cases, the Trojans suffered only moderate levels of dynamical erosion, with the most compact systems (those with aN less than or equal 18 AU) losing around 50% of their Trojans by the end of the integrations. In the 2:3 and 3:4 MMR scenarios, however, dynamical erosion was much higher with depletion rates typically greater than 66% and total depletion in the most compact systems. The 1:2 resonant scenarios featured disruption on levels intermediate between the non-resonant cases and other resonant scenarios, with depletion rates of the order of tens of percent. Overall, the great majority of plausible pre-migration planetary architectures resulted in severe levels of depletion of the Neptunian Trojan clouds. In particular, if Uranus and Neptune formed near their mutual 2:3 or 3:4 MMR and at heliocentric distances within 18 AU (as favoured by recent studies), we found that the great majority of pre-formed Trojans would have been lost prior to Neptune's migration. This strengthens the case for the great bulk of the current Neptunian Trojan population having been captured during that migration.

description: The global road network is expanding at an unprecedented rate, threatening the persistence of many species. Yet, even for the most endangered wildlife, crucial information on the distance up to which roads impact species abundance is lacking. Here we use ecological threshold analysis to quantify the road-effect zone (REZ) for the critically endangered western chimpanzee (Pan troglodytes verus). We found: (1) the REZ extends 5.4 km (95% CI [4.9–5.8 km]) from minor roads and 17.2 km (95% CI [15.8–18.6]) from major roads, the latter being more than three times wider than a previous estimate of the average REZ for mammals; and (2) only 4.3% of the chimpanzees’ range is not impacted by existing roads. These findings reveal the high sensitivity and susceptibility of nonhuman primates to roads across West Africa, a region undergoing rapid development, and can inform the implementation of more effective guidelines to mitigate road impacts.

description: Mixing of a passive scalar in the peripheral region close to a wall is investigated by means of accurate direct numerical simulations of both a three-dimensional Couette channel flow at low Reynolds numbers and a two-dimensional synthetic flow. In both cases, the resulting phenomenology can be understood in terms of the theory recently developed by Lebedev and Turitsyn [Phys. Rev. E 69, 036301, 2004]. Our results prove the robustness of the identified mechanisms responsible for the persistency of scalar concentration close to the wall with important consequences in completely different fields ranging from microfluidic applications to environmental dispersion modeling.

description: The New Year is a time for celebration. It is a time filled with high hopes and new possibilities. It is a time for reflection and a time for setting goals and aspirations for the months that follow. As we dive deeper into 2025, I've decided that one of my professional goals (for 2025 and beyond) will be to minimize my interaction with commercial academic publishers and to more fully support non-profit and community-led alternatives. This post attempts to explain why.

Student incivility in higher education of Afghanistan: Lecturers’ perspectives

description: The study investigated lecturers’ perceptions of student incivility in higher education of Afghanistan. It examined students’ behaviors that lecturers considered uncivil as well as causes and consequences of students’ uncivil behaviors. It also explored strategies lecturers used to address student incivility and to what extent they rated the strategies effective. A survey questionnaire and interview protocols with open-ended questions were used to collect data for the study. Descriptive and inferential statistics, and thematic analysis, were utilized to analyze the data. The study revealed that the participants considered threatening, harassing comments, belittling, making waseta, complaining about a lecturer, and cheating on exams as extremely uncivil behaviors. The participants believed that society, students, lecturers, and institutions were the major sources of student incivility. They believed that student incivility had negative impacts on learning environment (e.g. interrupted the normal flow of the class), lecturers (reduced their interest in teaching), and students (e.g. made them lose their concentration). Lecturers used a number of strategies including friendly verbal reminders and talking to a student in private and in front of other students to deal with student incivility, and they suggested individual and institutional strategies to cope with students’ uncivil behaviors. The study recommends universities to develop a policy to address incivility in order to create a safe learning environment for lecturers, students, and other stakeholders.

description: An alternate form of discrete potential Boussinesq equation is proposed and its multisoliton solutions are constructed. An ultradiscrete potential Boussinesq equation is also obtained from the discrete potential Boussinesq equation using the ultradiscretization technique. The detail of the multisoliton solutions is discussed by using the reduction technique. The lattice potential Boussinesq equation derived by Nijhoff et al. is also investigated by using the singularity confinement test. The relation between the proposed alternate discrete potential Boussinesq equation and the lattice potential Boussinesq equation by Nijhoff et al. is clarified.

The foundations of flourishing and our obligations to infants
Creators: name: Joiner, GE
Publisher: name: University Of Tasmania
Year: 2023

description: In this thesis I argue that we have a moral obligation to create the kind of conditions that will assist infants to acquire the foundational brain functioning which will enable them to flourish. These conditions, according to neuroscientific evidence, include immersion in a loving, responsive environment with an enduring other. Yet, an obligation to commit to such a relationship would seem to compromise a parent's right to be a fully-developed autonomous individual themselves. Thus we are faced with a dilemma in which the rights of the child seem pitted against the rights of the parent ‚Äö- usually the mother. I suggest that a way through this impasse is to challenge some assumptions about what it takes for an adult to be a fully developed individual. In particular, the liberalist tradition has assumed that autonomy and independence are the characteristics of a fully-developed person. Feminists have largely accepted this assumption and this has often led to the conclusion that women need to adopt traditional male roles ‚Äö- as paid employment was where status and respect resided, and was the means to independence. Of course, to take on such roles women have needed to engage in work and utilize childcare. I argue that the dilemma can be resolved by rejecting the liberal model of autonomy in favour of an alternative model, according to which true maturation is found in interdependence and social affiliation. Rather than being an obstacle to one's own development, the demanding relationship involved in loving and nurturing a child will contribute to a parent's development as a fully mature individual.

description: Intercultural competencies are crucial when collaborating effectively with people in different contexts to solve shared problems. This systematic literature review analyzed the content of scientific evidence from 2016 to 2023 of the publications in the Web of Science and Scopus databases on intercultural competency development and international collaboration in higher education. First, a systematic mapping study was carried out, and then selection criteria were applied to choose the articles to be fully reviewed, leaving a remainder of 50 studies. The analysis focused on three main components: intercultural competencies, collaboration, and internationalization. The evidenced results highlight that the following predominate: (a) qualitative studies, especially case study designs in the pedagogical area; (b) the topics of intercultural competencies and collaborative learning; (c) findings related to intercultural awareness and motivation; (d) the objective of intercultural competencies to prepare the students for intercultural interactions; and (e) attitude as the leading indicator measured in the studies. This study aims to be of value to academic and scientific communities interested in internationalization, collaboration, globalization, and educational innovation.
