Factors influencing the coexistence of bromeliad-dwelling chironomids on Ilha do Cardoso, Brazil
Creators: name: Letaw, Alathea Diana
Publisher: name: University of British Columbia
Year: 2016

description: Species interactions can influence the spatial distribution of organisms and the composition of local communities. To investigate how interactions influence the coexistence of invertebrates living in bromeliad phytotelmata, I combined methodological development and empirical exploration with the aim of understanding: 1) Which species in a community show signs of strong interactions, 2) Whether predators influence the outcome of competitive interactions and 3) Whether equalizing or stabilizing interactions between species change depending on context. To detect interactions between species given observational field data, I designed a method of finding negative co-occurrence patterns (using checkerboard units) between species based on their abundances in nature. Using this method, I found that three chironomid (Diptera: Chironomidae) species showed very strong negative co-occurrence patterns, suggesting that they experience net negative interactions (e.g. competition) or habitat filtering. Next, I performed a predator-addition experiment to assess the importance of predators in mediating the coexistence of the three chironomid species. Three predator species were added to bromeliads containing the three chironomid species. Although field observations suggested that at least one chironomid species should improve performance in the absence of predators, there was only a slight differential response to predators. Furthermore, one species of chironomid was competitively superior to the others in both the presence and absence of predators. We suspect that differing habitat preferences and the presence of other prey may be more important to coexistence than the presence or absence of predators alone. Finally, I performed an experiment to assess how habitat and ontogeny affect the outcome of competition between the two most common chironomid species. When reared at the same body size, the two chironomids exhibited a stable relationship that we term here asymmetric equivalence: in one species experiences the world neutrally but the other does not. However, when species differed in their ontogenetic stage, the asymmetric equivalence disappeared. Taking all three studies together, I found that competition, but not predation, is an important factor in chironomid coexistence, but that differences in context lead to different coexistence outcomes.

description: We propose to correlate transmittance maps and spectral-density maps of planar junctions, in order to analyze quantitatively and in detail spin-dependent transport calculations. Since spectral-density maps can be resolved with respect to atom, angular momentum, and spin, the resulting correlation coefficients reveal unequivocally, e.g., which layers or which orbitals determine the tunnel conductances. Our method can be used for transport calculations within the Landauer-Büttiker formalism. Its properties and features will be discussed by means of a pure bcc Fe(001) lead as well as an extensively studied Fe(001)/MgO/Fe(001) planar tunnel junction.

description: In 2017, the UK Government published Transforming Children and Young People’s Mental Health Provision: A Green Paper (Department for Education & Department of Health, 2017), making clear that their intention is to place schools at the forefront of a national strategy to improve the mental wellbeing of children. The Special Educational Needs and Disability Code of Practice (SEND CoP; Department for Education & Department of Health, 2015) includes Social, Emotional and Mental Health as one primary area of SEND, emphasising a graduated approach to intervention, beginning with high-quality teaching. Taken together, the clear implication is that schools should arrange provision to promote children’s wellbeing at the universal level, not just at the targeted and specialist levels. With its emphasis upon evidence-based actions, the New Economics Foundation’s (NEF’s) Five Ways to Wellbeing (Aked et al., 2008) is proposed here as a framework for organising provisions. Relevant evidence-based programs, as well as strategies and procedures, are presented, each of which is universally applicable, relevant across primary and secondary phases, and linked to the NEF’s Five Ways.

description: We present high resolution imaging of the low order (J=1 and 2) CO line emission from the z = 3.93 submillimeter galaxy (SMG) MM18423+5938 using the Expanded Very Large Array, and optical and near-IR imaging using the Canada-France-Hawaii Telescope. This SMG with a spectroscopic redshift was thought to be gravitationally lensed given its enormous apparent brightness. We find that the CO emission is consistent with a complete Einstein ring with a major axis diameter of ~ 1.4", indicative of lensing. We have also identified the lens galaxy as a very red elliptical coincident with the geometric center of the ring and estimated its photometric redshift z~1.1. A first estimate of the lens magnification factor is m~12. The luminosity L'_CO(1-0) of the CO(1-0) emission is 2.71+/-0.38 x10^11/m K km s^-1 pc^2, and, adopting the commonly used conversion factor for ULIRGs, the molecular gas mass is M(H_2) = 2.2 x10^11/m M_sol, comparable to unlensed SMGs if corrected by m ~ 12. Our revised estimate of the far-IR luminosity of MM18423+5938 is 2 x10^13/m < L_FIR < 3 x10^14/m L_sol, comparable to that of ULIRGs. Further observations are required to quantify the star formation rate in MM18423+5938 and to constrain the mass model of the lens in more detail.

description: Motion along semi-infinite straight line in a potential that is a combination of positive quadratic and inverse quadratic functions of the position is considered with the emphasis on the analysis of its quantum-information properties. Classical measure of symmetry of the potential is proposed and its dependence on the particle energy and the factor $\mathfrak{a}$ describing a relative strength of its constituents is described; in particular, it is shown that a variation of the parameter $\mathfrak{a}$ alters the shape from the half-harmonic oscillator (HHO) at $\mathfrak{a}=0$ to the perfectly symmetric one of the double frequency oscillator (DFO) in the limit of huge $\mathfrak{a}$. Quantum consideration focuses on the analysis of information-theoretical measures, such as standard deviations, Shannon, Rényi and Tsallis entropies together with Fisher information, Onicescu energy and non--Gaussianity. For doing this, among others, a method of calculating momentum waveforms is proposed that results in their analytic expressions in form of the confluent hypergeometric functions. Increasing parameter $\mathfrak{a}$ modifies the measures in such a way that they gradually transform into those corresponding to the DFO what, in particular, means that the lowest orbital saturates Heisenberg, Shannon, Rényi and Tsallis uncertainty relations with the corresponding position and momentum non--Gaussianities turning to zero. A simple expression is derived of the orbital-independent lower threshold of the semi-infinite range of the dimensionless Rényi/Tsallis coefficient where momentum components of these one-parameter entropies exist which shows that it varies between $1/4$ at HHO and zero when $\mathfrak{a}$ tends to infinity. Physical interpretation of obtained mathematical results is provided.

Educational Psychology and the Dissemination of Evidence to Professional Practice
Creators: name: Sedgwick, A.

Publisher: name: School of Psychology, University of East London
Year: 2021

description: The purpose of this reflective practice paper is twofold: firstly, to review the concepts of evidence-based practice (EBP) and practice-based evidence (PBE) within the discipline of educational psychology and, secondly, to consider how research evidence can be effectively disseminated to inform educational psychologists’ (EPs’) professional practice. The unique contribution that EPs can make to the evidence base is described before exploring the extent to which EPs’ general practice is based on the best available scientific evidence. Finally, a dissemination plan is outlined that includes a discussion regarding the critical role of Implementation Science (Blase et al., 2012). The paper concludes that, although sparse, the existing literature suggests EPs are not basing their practice on well-evidenced techniques. Also, effective dissemination must include Implementation Science if sustainable changes are to be made at an organisational level.

description: The magnetic form factor of YbInNi4 has been determined via the flipping ratios R with polarized neutron diffraction and the scattering function S(Q,w) was measured in an inelastic neutron scattering experiment. Both experiments were performed with the aim to determine the crystal-field scheme. The magnetic form factor clearly excludes the possibility of a \Gamma7 doublet as the ground state. The inelastic neutron data exhibit two, almost equally strong peaks at 3.2 meV and 4.4 meV which points, in agreement with earlier neutron data, towards a \Gamma8 quartet ground state. Further possibilities like a quasi-quartet ground state are discussed.

Testing inhabitant agency in interactive architecture : a user-centered design and research approach
Creators: name: Costa Maia, Sara
Publisher: name: University of British Columbia
Year: 2016

description: This thesis assembled, tested and demonstrated an inhabitant-centered approach for research and design in Interactive Architecture (IA). It takes an initial step in addressing a critical gap in the field concerning the lack of empirical evidence to support IA’s fundamental claims, especially regarding inhabitant experience. The approach focused on investigating the question of whether inhabitant experience of interactive architecture (IA), presumably dependent on different models of interaction, could support one of the primordial rationales for the social relevance of IA. The rationale states that IA holds the potential to empower inhabitants in participating in the continuous formation of their environment. However, there is no published evidence to date to corroborate the statement’s validity. In fact, very little research has been done to date on inhabitant experience of interactive spaces in general, hindering our ability to justify its use or to properly ground design decisions. Therefore, this thesis presents an exploratory investigation, set to form the basis for the study of agency and empowerment in IA, and aiming to demonstrate an approach to tackle the problem of user-centered design and research in the field. An extensive literature review is thus conducted, from the concept of agency in the social sciences to an overview of the pertinent literature on interaction. Finally, an approach is demonstrated to generate empirical evidences regarding agency in IA. For that, an IA space is designed (comprehending four different models of interaction), assembled and tested, grounded on two user-centered design studies. The first study was an anticipated experience diary study, where 17 participants reported their imagined daily experience with an IA concept. The second study was a user experience survey where 30 participants inhabited and experienced the assembled IA space. This thesis successfully demonstrated a user centered approach for evaluating interaction in IA design concepts, especially with regard to the possibility of fulfilling one of IA’s many untested claims, making explicit the problems and opportunities observed along the process.

description: Let ${\cal N}_{c_1,...,c_t}$ be the variety of polynilpotent groups of class row $(c_1,...,c_t)$. In this paper, first, we show that a polynilpotent group $G$ of class row $(c_1,...,c_t)$ has no any ${\cal N}_{c_1,...,c_t,c_{t+1}}$-covering group if its Baer-invariant with respect to the variety ${\cal N}_{c_1,...,c_t,c_{t+1}}$ is nontrivial. As an immediate consequence, we can conclude that a solvable group $G$ of length $c$ with nontrivial solvable multiplier, ${\cal S}_nM(G)$, has no ${\cal S}_n$-covering group for all $n>c$, where ${\cal S}_n$ is the variety of solvable groups of length at most $n$. Second, we prove that if $G$ is a polynilpotent group of class row $(c_1,...,c_t,c_{t+1})$ such that ${\cal N}_{c'_1,...,c'_t,c'_{t+1}}M(G)\neq 1$, where $c'_i\geq c_i$ for all $1\leq i\leq t$ and $c'_{t+1}>c_{t+1}$, then $G$ has no any ${\cal N}_{c'_1,...,c'_t,c'_{t+1}}$-covering group. This is a vast generalization of the first author's result on nilpotent covering groups (Indian\ J.\ Pure\ Appl.\ Math.\ 29(7)\ 711-713,\ 1998).

description: Background. Hearing aid technology has proven successful in the rehabilitation of hearing loss, but its performance is still limited in difficult everyday conditions characterized by noise and reverberation. Objectives. Introduction to the current state of hearing aid technology and presentation of the current state of research and future development. Methods. Current literature is analyzed and several specific new developments are presented. Results. Both objective and subjective data from empirical studies show the limitation of current technology. Examples of current research show the potential of machine-learning based algorithms and multi-modal signal processing for improving speech processing and perception, of using virtual reality for improving hearing device fitting and of mobile health technology for improving hearing-health services. Conclusions. Hearing device technology will remain a key factor in the rehabilitation of hearing impairment. New technology such as machine learning, and multi-modal signal processing, virtual reality and mobile health technology will improve speech enhancement, individual fitting and communication training.

description: Within the model of rectangular potentials and different effective masses of electrons in different elements of plane two-barrier resonance tunnel structure there is developed a theory of spectral parameters of quasi-stationary states and active conductivity for the case of mono-energetic electronic current interacting with electromagnetic field. It is shown that the two-barrier resonance tunnel structure can be utilized as a separate or active element of quantum cascade laser or detector. For the experimentally studied In$_{0.53}$Ga$_{0.47}$As/In$_{0.52}$Al$_{0.48}$As nano-system it is established that the two-barrier resonance tunnel structure, in detector and laser regimes, optimally operates (with the biggest conductivity at the smallest exciting current) at the quantum transitions between the lowest quasi-stationary states.

description: L’articolo parte dalla questione della definizione di «classico» riguardo ai prodotti narrativi destinati a giovani lettori e sulla sua legittimità, passando in esame i tre modi con cui si sono avvicinati i giovani lettori al mondo della cultura: l’avvicinamento alla cultura classica; l’avvicinamento ai «classici» della letteratura colta e, infine, la riscrittura e/o il riuso di racconti esemplari. La conclusione mostra una persistente ambivalenza: da un lato, la continuità con il passato, e con istanze didascaliche, mentre dall’altro, gli autori hanno maturato una piena consapevolezza di sé e del loro ruolo di scrittori tout court, quand’anche si rivolgano ad un pubblico particolare. In questa prospettiva, l’autore è finalmente libero di costruire i suoi viaggi, sollecitando la risposta ludica del suo lettore. -------------------------- The paper starts from the definition of «classic» referring to literature for children and from its legitimacy; then, it analyses the three kinds, usually, diffused to bring young readers closer to cultural universe: the approach to ancient literature and mythology; the approach to literary masterpieces and, finally, writing back important novels. Summing up, there is a persistent ambivalence: on one side, there is a clear continuity with the past and with a didactic attitude; on the other, the authors have, finally, become conscious of their intellectual, without any reference to their privileged target. In this perspective, the novelist is finally free to describe his/her travels and to encourage playing habits in his/her readers.

Optimization of energy consumption schedule of residential loads and electric vehicles
Creators: name: Yao, Enxin
Publisher: name: University of British Columbia
Year: 2016

description: In the current electrical grid, utility companies have begun to use demand side management (DSM) programs and time-of-use (TOU) pricing schemes to shape the residential load profile. However, it is difficult for the residential users to respond to the pricing signal and manually manage the operation of various household appliances. Hence, the autonomous energy consumption scheduling of residential loads and electric vehicles (EVs) is necessary for the users to benefit from the DSM programs. In this thesis, we propose different algorithms to schedule the energy consumption of residential loads and EVs, and provide ancillary services to the electrical grid. First, we study the DSM for areas with high photovoltaic (PV) penetration. Since many rooftop PV units can be integrated in the distribution network, the voltage rise issue occurs when the reverse power flow from the households to the substation is significant. We use stochastic programming to formulate an energy consumption scheduling problem, which takes into account the voltage rise issue and the uncertainty of the power generation from PV units. We propose an algorithm by solving the formulated problem and jointly shave the peak load and reduce the reverse power flow. Subsequently, we study using the EVs to provide the frequency regulation service. We formulate a problem to schedule the hourly regulation capacity of the EVs using the probabilistic robust optimization framework. Our formulation takes into account the limited battery capacity of the EVs and the uncertainty of the automatic generation control (AGC) signal. An efficient algorithm is proposed to solve the formulated problem based on duality. Last but not least, we study the market participation of an aggregator which coordinates a fleet of EVs to provide frequency regulation service to an independent system operator (ISO). The two-settlement market system (i.e., the day-ahead market (DAM) and real-time market) is considered. We analyze two types of DAMs based on the market rules of New York ISO and California ISO. We formulate a problem to determine the bid for the aggregator in the DAM using stochastic program and conditional value at risk. Efficient algorithms are proposed to tackle the formulated problem.

description: Recent experimental results [A. Rusydi et al., Phys. Rev. Lett. 97, 016403 (2006)] revealed the stability of a peculiar charge density wave (CDW) with odd period (three or five) in the coupled Cu$_2$O$_5$ spin ladders in Sr$_{14-x}$Ca$_x$Cu$_{24}$O$_{41}$, while the CDW with even period is unstable. Here we resolve this contradiction by solving the effective t-J model for the two coupled chains supplemented by the intersite interaction term V. Crucial to this finding is the novel interaction term V (responsible for the interladder repulsion between nearest neighbor holes), which is derived from the on-site Hubbard-like repulsion between electrons on the same oxygen sites but within two distinct orbitals which belong to two neighboring Cu$_2$O$_5$ ladders in the charge transfer model.

description: Il saggio ricostruisce, dopo una necessaria premessa per descrivere le principali vicende storiche, la politica educativa attuata in Bosnia Erzegovina dopo gli accordi di Dayton del 1995 che segnarono la fine delle guerre nei Balcani. Il progetto «due scuole sotto un tetto» rappresentò un passaggio che fu definito come temporaneo, ma che è tuttora in atto e che ha prodotto scuole con una netta separazione su base etnica. In questo contesto, Srebrenica, la città della Bosnia in cui nel 1995 ebbe luogo il genocidio di più di 8000 persone, diventa esempio di rinascita: il progetto Srebrenica city of hope messo in atto da Irvin Mujcic che fu profugo in Italia e che lasciò la sua città d’origine a 5 anni, per farvi ritorno ormai adulto dopo la guerra, definisce la necessità di costruire percorsi di pace, tanto nell’ambito delle politiche educative nazionali, quanto nel contesto sociale all’esterno della scuola. The essay analyzes the educational policy implemented in Bosnia and Herzegovina after Dayton agreements (1995) which marked the end of the Balkans wars. The national project «Two schools under one roof» represented a step which was defined as temporary, but which is still ongoing and which has produced schools with a clear separation on an ethnic basis. In this context, Srebrenica, the bosnian city where the genocide of more than 8000 people took place in july 1995, becomes an example of rebirth: the project «Srebrenica city of hope» implemented by Irvin Mujcic who was a refugee in Italy during the war, defines the need to build paths of peace both in the context of national educational policies and in the social context outside the school.

Graphene-based construction materials: experimentation and application development
Creators: name: POLVERINO, SALVATORE
Publisher: name: Universit� degli studi di Genova

description: The construction sector is entering the new era of production, construction and management of Industry 4.0. The development of smart and resilient technologies focused on the user and the environment has significant potential to improve the ways of experiencing indoor and outdoor spaces. This scenario generates new opportunities to exploit innovation to create the conditions for human well-being and to contribute to the future of the Earth.
The construction sector is in a period of transition. On the one hand, there is a demand for construction with high technological content, capable of incorporating innovations at low cost, low environmental impact, low energy consumption, safe and resilient, adaptable, convertible, transformable over time and personalised; on the other hand, there is a continued reliance on traditional building approaches/solutions that only partially meet the new requirements.
In this context, the research into new materials to produce innovative construction components capable of contributing to the achievement of the above-mentioned objectives is one of the areas of contemporary development. Among them are included two-dimensional materials that owe their name to their particular structure, consisting of a single atomic layer.
The event that enabled such a reduction in the size scale was the isolation of graphene, a material with unique properties and numerous possible applications. Its potential uses are currently being studied and tested, as demonstrated by the numerous research programmes on the subject, aimed at transferring technology from research laboratories to industry.
This PhD research aims to investigate the potential applications of graphene in the field of cementitious composites and polymer-based coatings. The activities carried out included: a critical analysis of the state of the art of the most recent applications in the field of construction; the consequent choice of possible composite materials graphene and graphene-related materials based; the design and development of an experimental campaign; the proposal and final verification of the applications in the construction sector. The activities were carried out in collaboration with the Graphene Labs of the Italian Institute of Technology (IIT).

description: Frequentare la letteratura per l’infanzia e l’adolescenza educa al piacere del leggere e alla costruzione di competenze di literacy ma questa frequentazione pare essere anche una via promettente per sollecitare in bambini e bambine riflessioni intorno alle capacità di resilienza. Le ragioni sono molteplici: nutre l’immaginazione, rafforza l’alfabetizzazione letteraria ed estetica, rinsalda i comportamenti morali e offre mondi fittizi in cui giovani lettrici e lettori, catapultati in un contesto di sfide educative, possono, sebbene per via finzionale, fare pratica dei problemi della vita, imparare ad affrontare eventi abbruttenti e disumanizzanti e trarre forza dai traumi e dalle lacerazioni della propria esistenza. Nel saggio si indagano alcuni generi letterari (giallo, noir, thriller e fiabe) e le ragioni che li rendono più adatti, rispetto ad altre forme narrative, ad interpellare, provocare e interrogare i nostri paesaggi resilienti. Children’s and young adult (YA) literature cultivates the pleasure of reading and contributes to building literacy skills. However, it also seems to offer a promising contribution to discussing resilience with children. There are many reasons for this: it nourishes imagination, reinforces literary and aesthetic literacy, promotes moral beliefs and reasoning and offers fictional worlds in which young readers can become familiar with life problems, learn to face brutalising and dehumanising events and gain strength to overcome traumas and wounds in their own lives. This essay explores the literary genres, detective stories, roman noir, thrillers and fairy tales, and the reasons why these could be more appropriate than others to engage with engage with children and stimulate discussions about resiliency.

description: Il saggio intende illustrare il modello pedagogico mazziniano, sviluppato grazie alla Scuola Italiana di Londra fondata da Mazzini nel 1841, e poi diffusosi nella penisola dopo la proclamazione del Regno d’Italia. Ad una prima parte dedicata alla Scuola londinese, segue l’analisi del piccolo ma significativo campione costituito dalla “Scuola serale e festiva per adulti” di Lajatico e della “Scuola Mazzini” di Carrara, in Toscana. La prima prese vita in una realtà agricola tra le più povere della campagna toscana, la seconda in una città caratterizzata dall’atipica industria del marmo. Ciò dimostra la capacità di adattamento e penetrazione delle strutture associative mazziniane nella variegata realtà politica ed economica dell’Italia postunitaria. The essay aims to illustrate Mazzini’s pedagogical model, developed thanks to the Italian School founded in London by the republican patriot in 1841, and its spreading in Italy after the proclamation of the Kingdom in 1861. The first part, dedicated to the Italian School in London, is followed by the analysis of the small but significant sample of the "Evening school for adults" of Lajatico and the "Mazzini’s School" of Carrara, both in Tuscany. Lajatico was maybe the poorest village of the Tuscany countryside, while Carrara a city characterized by the atypical marble industry. The two experiences demonstrate both the capacities of adaptation and penetration of Mazzini’s associations in the different political and economic reality of the Kingdom of Italy.

description: We present the details of a method for conducting a targeted, coherent search for compact binary coalescences. The search is tailored to be used as a followup to electromagnetic transients such as Gamma Ray Bursts. We derive the coherent search statistic for Gaussian detector noise and discuss the benefits of a coherent, multi-detector search over coincidence methods. To mitigate the effects of non-stationary data, we introduce a number of signal consistency tests, including the null SNR, amplitude consistency and several $χ^{2}$ tests. We demonstrate the search performance on Gaussian noise and on data from LIGO's fourth science run and verify that the signal consistency tests are capable of removing the majority of noise transients and the search gives an efficiency comparable to that achieved in Gaussian noise.

Gauss-Bonnet Holographic Superconductors

description: We study holographic superconductors in five dimensional Einstein-Gauss-Bonnet gravity both numerically and analytically. We find the critical temperature of the superconductor decreases as backreaction is increased, although the effect of the Gauss-Bonnet coupling is more subtle: the critical temperature first decreases then increases as the coupling tends towards the Chern-Simons value in a backreaction dependent fashion. We compute the conductivity of the system, finding the energy gap, and show that the effect of both backreaction and higher curvature is to increase the gap ratio $ω_g/T_c$, thus there is no universal relation for these superconductors.

Delayed impulsive stabilisation of discrete-time systems: a periodic event-triggering algorithm
Creators: name: Zhang, Kexue

Year: 2023
Subjects: subject: Optimization and Control (math.OC)

description: This paper studies the problem of event-triggered impulsive control for discrete-time systems. A novel periodic event-triggering scheme with two tunable parameters is presented to determine the moments of updating impulsive control signals which are called event times. Sufficient conditions are established to guarantee asymptotic stability of the resulting impulsive systems. It is worth mentioning that the event times are different from the impulse times, that is, the control signals are updated at each event time but the actuator performs the impulsive control tasks at a later time due to time delays. The effectiveness of our theoretical result with the proposed scheme is illustrated by three examples.

description: La situazione pandemica ha messo in primo piano la realtà contingente dell’uomo, la sua fragilità, la realtà della malattia e della morte, la paura del contagio. La domanda su cosa sia essenziale nell’esistenza umana assume, allora, nuove forme, recuperando la tradizione filosofica e sapienziale che antiche culture hanno elaborato e che oggi, nel mondo globalizzato in cui viviamo, non appaiono meno rilevanti di ieri. Il riferimento a studiosi che hanno ripreso in tempi recenti la questione del senso della vita e della felicità può essere utile, del resto, anche sul piano pedagogico e della storia dell’educazione; la descrizione della condizione “liquida” dell’uomo contemporaneo condotta da Z. Bauman, l’analisi esistenziale di V. E. Frankl, la questione del senso della vita nella psicologia positiva di M. E. P. Seligman, e la teoria del desiderio di R. Girard sono brevemente esaminati nella loro rilevanza per la ricerca pedagogica e per la storia dell’educazione contemporanee. The pandemic situation put in the foreground the contingent condition of man, his fragility, the reality of illness and death, the fear of contagion. The question of what is essential in human existence then takes on new forms, recovering the philosophical and wisdom tradition that ancient cultures have developed and which today, in the globalized world in which we live, seem no less relevant than yesterday. The reference to scholars who have recently taken up the question of the meaning of life and happiness can also be useful in the field of pedagogy and the history of education; the description of the “liquid” condition of contemporary man by Z. Bauman, the existential analysis of V.E. Frankl, the question of the meaning of life in M. E. P. Seligman’s positive psychology, and R. Girard's theory of desire are briefly examined in their relevance for contemporary educational research and the history of education.

description: The richness of optical and electronic properties of graphene attracts enormous interest. Graphene has high mobility and optical transparency, in addition to flexibility, robustness and environmental stability. So far, the main focus has been on fundamental physics and electronic devices. However, we believe its true potential to be in photonics and optoelectronics, where the combination of its unique optical and electronic properties can be fully exploited, even in the absence of a bandgap, and the linear dispersion of the Dirac electrons enables ultra-wide-band tunability. The rise of graphene in photonics and optoelectronics is shown by several recent results, ranging from solar cells and light emitting devices, to touch screens, photodetectors and ultrafast lasers. Here we review the state of the art in this emerging field.
