description: We propose a one-loop radiative Majorana-type neutrino-mass matrix without any kind of additional symmetries by introducing two leptoquark-like bosons only. In this scenario, we show that the anomaly appearing in the process $b\to s\ell\bar\ell$ can be explained without any conflicts against various constraints such as lepton-flavor violations, flavor-changing neutral currents, oblique parameters $ΔS,\ ΔT$, and the Drell-Yan process. We make the predictions for the flavor-violating lepton-pair production ($eμ$, $eτ$, and $μτ$) at the LHC, as well as the cross sections for pair production of these leptoquark-like bosons.

description: Brown dwarfs display Jupiter-like auroral phenomena such as magnetospheric H$α$ emission and coherent radio emission. Coherent radio emission is a probe of magnetospheric acceleration mechanisms and provides a direct measurement of the magnetic field strength at the emitter's location, both of which are difficult to access by other means. Observations of the coldest brown dwarfs (spectral types T and Y) are particularly interesting as their magnetospheric phenomena may be very similar to those in gas-giant exoplanets. Here we present 144 MHz radio and infrared adaptive optics observations of the brown dwarf WISEP J101905.63+652954.2 made using the LOFAR and Keck telescopes respectively. The radio data shows pulsed highly circularly polarised emission which yields a rotation rate of $0.32\pm0.03$ hr$^{-1}$. The infrared imaging reveals the source to be a binary with a projected separation of $423.0\pm1.6$ mas between components of spectral type T5.$5\pm0.5$ and T7.$0\pm0.5$. With a simple "toy model" we show that the radio emission can in principle be powered by the interaction between the two dwarfs with a mass-loss rates of at least $25$ times the Jovian value. WISEP J101905.63+652954.2 is interesting because it is the first pulsed methane dwarf detected in a low radio-frequency search. Unlike previous gigahertz-frequency searches that were only sensitive to objects with kiloGauss fields, our low-frequency search is sensitive to surface magnetic fields of $\approx 50$ Gauss and above which might reveal the coldest radio-loud objects down to planetary mass-scales.

description: Introduction
HAVIC MED Novel 2 Test -- Videos, Metadata and Annotation was developed by the Linguistic Data Consortium (LDC) and is comprised of approximately 6,200 hours of user-generated videos with annotation and metadata.
To advance multimodal event detection and related technologies, LDC developed, in collaboration with NIST (the National Institute of Standards and Technology), a large, heterogeneous, annotated multimodal corpus for HAVIC (the Heterogeneous Audio Visual Internet Collection) that was used in the NIST-sponsored MED (Multimedia Event Detection) task for several years. HAVIC MED Novel 2 Test is a subset of that corpus, specifically, a collection of videos, metadata and annotation for the HAVIC project originally released to support the 2015 Multimedia Event Detection tasks.
Data
The data consists of videos of various events (event videos) and videos completely unrelated to events (background videos) harvested by a large team of human annotators. Each event video was manually annotated with a set of judgments describing its event properties and other salient features. Background videos were labeled with topic and genre categories.
All video files are in .mp4 format (h.264), with varying bit-rates and levels of audio fidelity and video resolution. Metadata and annotation for the videos are stored in a .tsv file.

description: We measure the 4.5 $μ$m thermal emission of five transiting hot Jupiters, WASP-13b, WASP-15b, WASP-16b, WASP-62b and HAT-P-22b using channel 2 of the Infrared Array Camera (IRAC) on the {\sl Spitzer Space Telescope}. Significant intrapixel sensitivity variations in Spitzer IRAC data require careful correction in order to achieve precision on the order of several hundred parts per million (ppm) for the measurement of exoplanet secondary eclipses. We determine eclipse depths by first correcting the raw data using three independent data reduction methods. The Pixel Gain Map (PMAP), Nearest Neighbors (NNBR), and Pixel Level Decorrelation (PLD) each correct for the intrapixel sensitivity effect in Spitzer photometric time-series observations. The results from each methodology are compared against each other to establish if they reach a statistically equivalent result in every case and to evaluate their ability to minimize uncertainty in the measurement. We find that all three methods produce reliable results. For every planet examined here NNBR and PLD produce results that are in statistical agreement. However, the PMAP method appears to produce results in slight disagreement in cases where the stellar centroid is not kept consistently on the most well characterized area of the detector. We evaluate the ability of each method to reduce the scatter in the residuals as well as in the correlated noise in the corrected data. The NNBR and PLD methods consistently minimize both white and red noise levels and should be considered reliable and consistent. The planets in this study span equilibrium temperatures from 1100 to 2000~K and have brightness temperatures that require either high albedo or efficient recirculation. However, it is possible that other processes such as clouds or disequilibrium chemistry may also be responsible for producing these brightness temperatures.

description: Background: Breast disorders may be noncancerous (benign) or cancerous (malignant). Breast cancer is by far the most frequent cancer among women with an estimated 1.67 million new cancer cases diagnosed in 2012.breast cancer is the leading reproductive cancer in Ethiopia with an estimated 12956 new cases and7089 deaths in 2012. Knowing the magnitude and associated factors of breast abnormality will help the government and other actors implementing strategies for early detection and minimization of breast abnormality occurrences in the community leading to reduced incidence of breast cancer. Objectives: The aim of this study is to assess the magnitude and associated factors of breast abnormalities among women in selected health centers in Addis Ababa city. Methods: The study was done in Addis Ababa, Ethiopia. The study population was all women above age of 18 attending the selected health centers at the time of the study. The study was conducted between April 1 and April 31, 2018. A facility based cross-sectional study design was employed. The total sample size of the study was 1173. Health centers were selected from sub cities proportionally based on their population size by simple random sampling technique. Data was collected using interview method and presence or absence of breast abnormality was determined by self-reporting of participants. Data was entered into Epi-info version7.1, cleaned and exported to SPSS v21 for analysis. Result: According to this study the magnitude of breast abnormality among women above the age of 18 in Addis Ababa city is 51(4.63%). Based on this analysis age ≥45yrs has odds ratio of 5.4[AOR =5.409(1.196-24.460)]. The odds ratio for first degree relative with breast abnormality history is 9.44[AOR = 9.435(3.123 - 28.508)]. Similarly the odds ratio for previous history of breast abnormality is 10.99[AOR = 10.991(3.051 - 39.599)]. Age at menstruation also have odds ratio for both ages 12 – 13yrs and > 13yrs [AOR = 0.120(0.023 -0.622), 0.128(0.028 - 0.591)]. respectively. Odds ratio for Women who breast fed is [AOR= 0.103(0.031 - 0.343)]. Conclusion: Magnitude of breast abnormality is 51(4.63%). Breast abnormality were found to be significantly associated with age above 44yrs, first degree relative breast abnormality history, previous history of breast abnormality age at menarche and exposure to breast feeding.

description: The subject of the dissertation is the analysis of modern trends in the design of sustainable ski destinations. In addition, the effects of the climate crisis on the industry are being recorded. The 3-5 Pigadia ski resort of Naoussa is used as a case study. Ski tourism is on the one hand an important part of the global tourism product and on the other hand it is an extremely volatile and influential industry. Initially, a bibliographic research was conducted on the subject, followed by a field research on the subject of the case study. A qualitative analysis of the data obtained from the research followed. Finally, suggestions were given for the improvement of the current situation in the example of the case study. The research showed that the climate crisis is the biggest threat to the design of sustainable ski destinations. In addition, competition in the industry pushes companies to take innovative interventions to ensure their survival. The 3-5 Pigadia ski resort is at a critical crossroads as it needs to be modernized and adapted to the new data.

description: Generating evidence on the use, effectiveness, and safety of new cancer therapies is a priority for researchers, health care providers, payers, and regulators given the rapid pace of change in cancer diagnosis and treatments. The use of real-world data (RWD) is integral to understanding the utilization patterns and outcomes of these new treatments among patients with cancer who are treated in clinical practice and community settings. An initial step in the use of RWD is careful study design to assess the suitability of an RWD source. This pivotal process can be guided by using a conceptual model that encourages predesign conceptualization. The primary types of RWD included are electronic health records, administrative claims data, cancer registries, and specialty data providers and networks. Careful consideration of each data type is necessary because they are collected for a specific purpose, capturing a set of data elements within a certain population for that purpose, and they vary by population coverage and longitudinality. In this review, the authors provide a high-level assessment of the strengths and limitations of each data category to inform data source selection appropriate to the study question. Overall, the development and accessibility of RWD sources for cancer research are rapidly increasing, and the use of these data requires careful consideration of composition and utility to assess important questions in understanding the use and effectiveness of new therapies.

description: We present the first experimental study of unpinning a spiral wave of excitation using a circularly polarized electric field. The experiments are conducted in the Belousov-Zhabotinsky(BZ) reaction, and the system is modeled using the Oregenator model. The mechanism of unpinning in the BZ reaction differs from that in the physiological medium. We show that the wave unpins when the electric force opposes the propagation of the spiral wave. We developed an analytical relation of the unpinning phase with the initial phase, the pacing ratio, and the field strength and verified the same.

description: Ever since the invention of Bell Laboratories Layer Space-Time (BLAST) in mid 1990s, the focus of MIMO research and development has been largely on pushing the limit of spectral efficiency. While massive MIMO technologies laid the foundation of high spectrum efficiency in 5G and beyond, the challenge remains in improving energy efficiency given the increasing complexity of the associated radio systems. With the substantial negative implications of climate change looming ever closer, minimizing energy use is a key dimension of achieving sustainability and is of paramount importance for any future technology. Thus, every aspect of future extreme MIMO system design, implementation, and operation will be scrutinized to maximize energy efficiency. An analysis of the massive MIMO 5G radio energy consumption at different loads leads to qualitative energy efficiency design goals for emerging extreme MIMO systems. Following this, we focus on novel operational and component technology innovations to minimize energy consumption.

description: We investigate the electrical conductivity and thermoelectric effects in topological crystalline insulators in the presence of short- and long-range impurity interactions. We employ the generalized Boltzmann formalism for anisotropic Fermi surface systems. The conductivity exhibits a local minimum as doping varies owing to the Van Hove singularity in the density of states originated from the saddle point in the surface states band structure. Suppression of the interband scattering of the charge carriers at high-energy Dirac points results in a maximum in the electrical conductivity. Whenever the Fermi level passes an extremum in the conductivity, Seebeck coefficient changes sign. In addition, it is revealed that profound thermoelectric effects can be attained around these extrema points.

description: Today, there is huge growth in the field of information technology. One of the problems that has caught the eye of science is the analysis of data, and in particular, the analysis of graphs in order to detect anomalies. There is extensive literature devoted to the detection of anomalies in non-attributed graphs, however, there are not many studies for anomaly detections in attributed graphs. This study is a novel proposal, which uses a simple, effective, and understandable methodology for anomaly detection in attributed static graphs. Theoretically, the methodology can be applied to each attributed graph, which follows a particular style: when the nodes’ attributes are a natural language and there can be a substance at the intersection of the attributes between the two nodes. Before reaching the methodology phase, the general process of discovering knowledge from data is examined, reference is made to basic concepts of graph theory, while the relevant literature and the existing methodologies for anomaly detection in static graphs are analyzed. Then, the specific methodology and the results are presented. Finally, the interpretation of the results, the future work, and the conclusions regarding the strength of the aforementioned study are formulated.

description: Quantum algorithms for simulating electronic ground states are slower than popular classical mean-field algorithms such as Hartree-Fock and density functional theory, but offer higher accuracy. Accordingly, quantum computers have been predominantly regarded as competitors to only the most accurate and costly classical methods for treating electron correlation. However, here we tighten bounds showing that certain first quantized quantum algorithms enable exact time evolution of electronic systems with exponentially less space and polynomially fewer operations in basis set size than conventional real-time time-dependent Hartree-Fock and density functional theory. Although the need to sample observables in the quantum algorithm reduces the speedup, we show that one can estimate all elements of the $k$-particle reduced density matrix with a number of samples scaling only polylogarithmically in basis set size. We also introduce a more efficient quantum algorithm for first quantized mean-field state preparation that is likely cheaper than the cost of time evolution. We conclude that quantum speedup is most pronounced for finite temperature simulations and suggest several practically important electron dynamics problems with potential quantum advantage.

description: The boundary Weyl anomalies live on a codimension-1 boundary, $\partial {\cal M}$. The entanglement entropy originates from infinite correlations on both sides of a codimension-2 surface, $Σ$. Motivated to have a further understanding of the boundary effects, we introduce a notion of reduction entropy, which, guided by thermodynamics, is a combination of the boundary effective action and the boundary stress tensor defined by allowing the metric on $\partial {\cal M}$ to fluctuate. We discuss how a reduction might be performed so that the reduction entropy reproduces the entanglement structure.

description: Atomic-scale engineering typically involves bottom-up approaches, leveraging parameters such as temperature, partial pressures, and chemical affinity to promote spontaneous arrangement of atoms. These parameters are applied globally, resulting in atomic scale features scattered probabilistically throughout the material. In a top-down approach, different regions of the material are exposed to different parameters resulting in structural changes varying on the scale of the resolution. In this work, we combine the application of global and local parameters in an aberration corrected scanning transmission electron microscope (STEM) to demonstrate atomic scale precision patterning of atoms in twisted bilayer graphene. The focused electron beam is used to define attachment points for foreign atoms through the controlled ejection of carbon atoms from the graphene lattice. The sample environment is staged with nearby source materials, such that the sample temperature can induce migration of the source atoms across the sample surface. Under these conditions, the electron-beam (top-down) enables carbon atoms in the graphene to be replaced spontaneously by diffusing adatoms (bottom-up). Using image-based feedback-control, arbitrary patterns of atoms and atom clusters are attached to the twisted bilayer graphene with limited human interaction. The role of substrate temperature on adatom and vacancy diffusion is explored by first-principles simulations.

description: In January 2014, the Same Sex Marriage Prohibition Act was legislated in Nigeria, inducing a steady migrational flow of queer Nigerians to the US. Using ethnographic data collected through oral history interviews and participant observation with queer Nigerian migrants who have resettled in the Greater Chicago area, this thesis seeks to illuminate that queer Nigerian migrants are subject to multiple necropolitical regimes throughout their migration experience. Initial crises in Nigeria can be linked to the state’s postcolonial insecurity and corruption. These are, then, substituted with the haunt of neoliberal capitalism and racism in the US and new tensions with queer identity politics. I argue that migration provides queer Nigerian migrants with comparatively better chances of survival than “salvation” from brutal regimes and that their continuous precarity, together with other complex socioeconomic structures surrounding their migration, becomes obscured under liberal, imperialist discourses on queer migration. To end, this thesis shows how the interlocutors forge transnational networks and perform care within these networks and their areas of residency to make “home.”

description: Background: Low birth weight is defined as birth weight of less than 2500 grams .It is a public health problem affecting 15%-20% of births worldwide. The great majority of low birth weight occurs in low and middle income countries especially in the most vulnerable population such as sub-Saharan countries which account 13% of low birth weight. The trend of low birth weight decline in Ethiopia from 14.6% in 2005 to 11% in 2011. But if these trends continue in this manner Ethiopia might not achieve the global nutrition target of low birth weight reduction by 30% in 2025. Food and nutrition are critically important to support healthy pregnancy. But food insecurity prevents many women meeting guideline for healthy eating during pregnancy. Inconsistency and little information between relationship of food insecurity and low birth weight was the rationally to study on this area. Objective: To assess the relationship between low birth weight and household food insecurity in public hospitals, Addis Ababa, Ethiopia. Methods: Unmatched case control study was conducted among mother with their term neonate in governmental hospital in Addis Ababa, Ethiopia. A total of 480 (120 cases and 360 controls) neonate was included in the study. Case was term baby weighed <2500grams and control was term baby weighed ≥2500 grams. In each selected hospital selection of case was made as case found and the next three eligible newborn was controls. The data were collected using interviewer administer structured questioner. Necessary permission to conduct the study obtained from research and ethics committee of Addis Ababa University and Addis Ababa health bureau. Data were entered into EPI data 3.1 computer programs and analyzed using STATA 14. Bivariate and Multivariate analysis was done to identify independent predictor of low birth weight using binomial and multivariate logistic regression. The adjusted odd ratio was used to determine the strength of association and corresponding CI was used to decide whether statically significant between the explanatory variable and outcome variable. Result: A total of 116 cases and 352 controls were included in the analysis. After adjusting potential confounder mothers in food insecure household were strongly associated with low birth weight AOR 3.58 CI (1.79-7.16). In addition MUAC, hypertension and age were independently associated with low birth weight with corresponding AOR of [AOR 7.7 CI (4.39-13.60)], [AOR 4.81 CI (2.33-9.93)] and [AOR 3.88 CI (1.35-11.15)]. xi Conclusion: Mothers from food insecure household were about four times more likely to give birth with low weight against their counterpart in governmental hospitals in Addis Ababa, Ethiopia. Beside hypertension, MUAC and early age were significantly associated with low birth weight. Key words: Low birth weight, Household, food insecurity, neonate, mothers.

description: Mini keynote presentation to AHE 22 on activating internal feedback mechanisms to reduce reliance on teacher support. The conventional approach to feedback beginning with peer review followed by teacher comment, writtten or verbal, has been altered dramatically in the paradigm outlined in this powerpoint. In this presentation, we posit that feedback should begin with the student and be self-generated/regulated. Following this, peer review should follow and the feedback cycle completed with teacher comments.

description: We introduce trilayer and multilayer moiré heterostructures that cannot be viewed from the ``moiré-of-moiré" perspective of helically-twisted trilayer graphene. These ``intrinsically trilayer" moiré systems feature periodic modulation of a local quasicrystalline structure. They open the door to realizing moiré heterostructures with vastly more material constituents because they do not constrain the lattice constants of the layers. In this manuscript, we define intrinsically multilayer patterns, provide a recipe for their construction, derive their local configuration space, and connect the visual patterns to physical observables in material systems.

State Aid Rules: HEI-Industry Collaborative Research in Ireland

subject: Commercial law

description: This thesis looks at the relevance of competition law to Higher Education Institutions (HEIs) in Ireland, and at how they can avoid contravening the EU’s state aid rules when working with industry. It was not originally projected that HEIs, as providers of a public service, would be constrained by EU competition law, but increasing emphasis on commercialisation means that they more frequently fall into its ambit. HEIs in the EU are encouraged to collaborate closely with Industry through EU and Member States funded schemes. This raises the possibility that the HEI might provide the Industry collaborator with indirect State Aid by making state-funded intellectual property available to them. There is a gap in the literature on the role of competition law on the commercialisation of the results of collaborative research by HEIs and this study explores whether funding mechanisms in Ireland for HEI-Industry collaborations are consistent with EU Competition law and adhere to State Aid Rules. Further, we consider, based on published information, if the approach of Irish HEIs is comparable with other EU Member States. This study finds that Ireland’s HEIs have one of the more robust frameworks for the awareness State Aid among Member States and that Ireland, uniquely in the EU, has Soft Law instruments specifically addressing the management of IP coming out of HEI-Industry collaborations. This study recommends that funding schemes, after a trial-period to demonstrate efficacy, should apply the EU’s general block exemption as the most effective means to avoid State Aid concerns.

description: We derive upper and lower bounds on the mass-radius ratio of stable compact objects in extended gravity theories, in which modifications of the gravitational dynamics via-{\' a}-vis standard general relativity are described by an effective contribution to the matter energy-momentum tensor. Our results include the possibility of a variable coupling between the matter sector and the gravitational field and are valid for a large class of generalized gravity models. The generalized continuity and Tolman-Oppenheimer-Volkoff equations are expressed in terms of the effective mass, density and pressure, given by the bare values plus additional contributions from the total energy-momentum tensor, and general theoretical limits for the maximum and minimum mass-radius ratios are explicitly obtained. As an applications of the formalism developed herein, we consider compact bosonic objects, described by scalar-tensor gravitational theories with self-interacting scalar field potentials, and charged compact objects, respectively. For Higgs type models, we find that these bounds can be expressed in terms of the value of the potential at the surface of the compact object. Minimizing the energy with respect to the radius, we obtain explicit upper and lower bounds on the mass, which admits a Chandrasekhar type representation. For charged compact objects, we consider the effects of the Poincaré stresses on the equilibrium structure and obtain bounds on the radial and tangential stresses. As a possible astrophysical test of our results, we obtain the general bound on the gravitational redshift for compact objects in extended gravity theories. General implications of minimum mass bounds for the gravitational stability of fundamental particles and for the existence of holographic duality between bulk and boundary degrees of freedom are also considered.

description: Silicon is still a dominating element in terms of industrial applications and also fundamental research. Silicon oxides play a key role for insulator layers in integrated circuits and coatings for opto-electric devices. A microscopic understanding of the silicon-oxide structure is therefore highly demanded. New nanostructured silicon compounds showing particular physical behavior have been discovered during the last decade. So, endohedrally doped silicon clathrates are promising materials for thermo-electric applications and tailored band-gaps. The study of the interaction between the guest atoms and the host silicon network is crucial to understand changes in physical properties. Also in the view of fundamental research silicon clathrates show exciting structural and electronic phase-transitions under high pressure. Access to the structural and electronic information in bulk amorphous silicon monoxide and complex silicon compounds can be achieved by the study of absorption edges. Non-resonant inelastic x-ray scattering is a powerful tool to measure shallow absorption edges using hard x-rays. This allows the study of low energy transitions under conditions which do not permit electrons and soft x-rays. In the present work, an algorithm is presented for the proper experimental extraction of momentum-transfer dependent scattering spectra. A comparison with ab-initio calculations can contribute significantly to the understanding of the experimental spectra. Therefore, the applicability and the limits of theoretical approaches are elaborated in a study of the pure elements silicon, magnesium and sodium. Based on these methodical advances, the disproportionation of bulk amorphous silicon monoxide is analyzed and compared to the interface clusters mixture model for the SiO structure. Complex nano-structured barium doped silicon networks are examined by the survey of the barium giant dipole resonance. The first observation of different modulations of the resonance depending on the structure will be presented and future applications on high-pressure research will be highlighted.

description: Let $G$ be a simply connected semisimple algebraic group with Lie algebra $\mathfrak g$, let $G_0 \subset G$ be the symmetric subgroup defined by an algebraic involution $σ$ and let $\mathfrak g_1 \subset \mathfrak g$ be the isotropy representation of $G_0$. Given an abelian subalgebra $\mathfrak a$ of $\mathfrak g$ contained in $\mathfrak g_1$ and stable under the action of some Borel subgroup $B_0 \subset G_0$, we classify the $B_0$-orbits in $\mathfrak a$ and we characterize the sphericity of $G_0 \mathfrak a$. Our main tool is the combinatorics of $σ$-minuscule elements in the affine Weyl group of $\mathfrak g$ and that of strongly orthogonal roots in Hermitian symmetric spaces.

description: Η ενσωμάτωση της λογοτεχνίας στην τάξη των Αγγλικών, αν και ιδιαίτερα ωφέλιμη, υφίσταται σοβαρή υποτίμηση από το Ελληνικό εκπαιδευτικό πλαίσιο. Ταυτόχρονα, η μελέτη ή η συζήτηση διαφόρων θεμάτων φύλου, όπως τα έμφυλα στερεότυπα, δεν περιλαμβάνονται στα σχολικά βιβλία του δημοτικού. Για τη δημιουργία της παρούσας μεταπτυχιακής εργασίας διεξήχθη μια σειρά από τρία δίωρα μαθήματα στην έκτη τάξη του 3ου πειραματικού δημοτικού σχολείου στον Εύοσμο της Θεσσαλονίκης. Το μυθιστόρημα Μικρές Κυρίες, της Λουίζα Μέι Άλκοτ, χρησιμοποιήθηκε ως πηγή διερεύνησης των έμφυλων στερεοτύπων στην Αμερική του 19ου αιώνα, ενώ ενθάρρυνε τους μαθητές να κάνουν παραλληλισμούς με τον σύγχρονο κόσμο. Τα μαθήματα περιλάμβαναν διάφορες δραστηριότητες δημιουργικής γραφής και θεάτρου, συζητήσεις, λεπτομερή ανάλυση ορισμένων τμημάτων του κειμένου και τη δημιουργία αφισών. Η εφαρμογή των μαθημάτων στην τάξη αποδείχτηκε ιδιαίτερα επωφελής για την προσωπική εξέλιξη των μαθητών, οι οποίοι απέκτησαν μια πιο πλήρη και ολοκληρωμένη κατανόηση των έμφυλων στερεοτύπων, ενώ παράλληλα ανέπτυξαν τις γλωσσικές τους δεξιότητες, τις ικανότητες εξαγωγής συμπερασμάτων, κριτική τους σκέψη και τη δημιουργικότητά τους
description: The incorporation of literature in the EFL classroom, though highly beneficial, is seriously underestimated in the Greek educational context. At the same time, the study or discussion of various gender issues, such as the gender stereotypes, are not included in the primary school textbooks. For the creation of this postgraduate thesis, a series of three two-hour lessons were conducted in the sixth grade of the 3rd Experimental Primary School of Evosmos in Thessaloniki. The novel Little Women, by Louisa May Alcott, was employed as a source for investigating gender stereotypes in 19th-century America and for encouraging learners to draw parallels with the contemporary world. The lessons incorporated various creative writing and drama activities, as well as discussions, a close-analysis of some parts of the text and the creation of posters. The implementation of the lessons in the classroom was proved highly advantageous for the learners’ personal growth, who gained a more complete and comprehensive understanding of gender stereotypes, while at the same time, they developed their language skills, inference abilities, critical thinking and creativity
