A Story Told

How do we educate our future generations about topics that are difficult to discuss? Oftentimes, children ask us questions that make us think, How do I respond to this? It is essential for our young generations to understand the history of racism, its present manifestations, and solutions and methods of action in order for a bright and revolutionary future. It is not always a simple task for children to comprehend such intricate topics. However, through text and pictures in storybooks, children can better grasp the concepts of such subject matter. A Story Told shares the story of young children in an elementary setting who face concerns around racism when coming into school on a day-to-day basis. Eight-year-old Olivia must encounter difficulties of being one of few children in her grade who appear to be different on the outside from her fellow classmates. Olivia tells the story of her family and educators, and brings light to her friends,classmates, and teachers about racism. As this story is framed around the elementary-aged audience, all members of society can learn something from it

An Investigation of Social Skills and Antisocial Behaviors of At-Risk Youth: Construct Validation of the Home and Community Social Behavior Scales

The major purpose of this dissertation was to investigate the construct validity of a new parent rating scale, the Home and Community Social Behavior Scales (HCSBS), that was used to measure the social skills and antisocial behaviors of at-risk youth in Northern Utah. The results indicate that the HCSBS possesses strong internal consistency with high alphas. Convergent validity with both teacher ratings and student self-ratings of social competence and antisocial behavior appeared slight. Discriminant validity was indicated by the near zero correlations between the HCSBS and the KTEA. The instrument appeared able to detect group differences as indicated by the large and clinically significant effect size differences between at-risk and non-at-risk sample mean scores, as well as a 92.37 correct classification percentage. Finally, the factor analysis of the HCSBS suggested four social competency factors and three antisocial behavior factors, which were extremely similar to the results obtained for the teacher version of the instrument. Directions for future research, as well as implications and limitations of the current study, are noted

Common Dimensions of Social Skills of Children and Adolescents: A Review and Analysis of the Literature

Previous research in the area of social skills of children and adolescents has resulted in confusion over the number and name of empirically derived dimensions. While much work has been done to derive empirically based taxonomies of child and adolescent problem behaviors, such is not the case for positive social behaviors. The present study conducted an extensive review, analysis, and synthesis of over two decades of factor analytic research on child and adolescent social skills to derive an empirically based taxonomy. Results suggest five dimensions that occurred in over one third of the studies: Peer Relations, Self-Management, Academic, Cooperation, and Assertion. The most common social skills associated with these dimensions are presented. It is advised that clinicians and researchers begin employing this taxonomy to: (a) provide a nomenclature by which to refer to the five positive social skill patterns, (b) identify dimensions on which children or adolescents may have deficits, (c) design interventions to increase the occurrence of these skills, all of which have been empirically related to important social outcomes, (d) measure the effects of interventions, and (e) aid in theory development

Reported Benefits of Yoga in Middle Schools: A Review of the Literature

Middle school is a time of adjustments in youth: physical, intellectual, and social changes often result in stress. Middle school students are vulnerable to academic, behavioral, and mental health problems. Yoga is an Indian discipline practiced for health and relaxation. School-based yoga programs are becoming increasingly common given their potential benefits for students. We conducted a literature review of studies of middle school-based yoga programs, focusing on the reported benefits for students. We identified and retrieved 12 studies from electronic databases including Education Resources Information Center, PsycINFO, and Google Scholar that met inclusion criteria; (a) examined the benefits of yoga as the primary intervention conducted in a middle school setting with students ages 10 to 15 years old, (b) was published by June 2022, (c) was reviewed either by a journal editorial board or by a student’s dissertation or thesis committee, (d) was available in English, and (e) a full text copy was available. Results of studies were synthesized by clustering findings into common domains. Study results suggested that middle school-based yoga interventions showed mental health, executive functioning, physical, social, and academic benefits for students. Yoga also showed benefits for middle school students who were stressed, anxious, or depressed, and those at risk. We provide considerations for those contemplating the implementation of yoga in middle schools

Principal torus bundles of Lorentzian S-manifolds and the {\phi}-null Osserman condition

The main result we give in this brief note relates, under suitable hypotheses, the {\phi}-null Osserman, the null Osserman and the classical Osserman conditions to each other, via semi-Riemannian submersions as projection maps of principal torus bundles arising from a Lorentzian S-manifold.Comment: 9 pages, no figur

First record of Ribes uva-crispa L. (Grossulariaceae) from the Madonie Mts., a new species of the Sicilian flora.

In this study, a first record of Ribes uva-crispa L. (Grossulariaceae) – a new species of the Sicilian flora – from the Madonie Mts. is reported. The autochthonous and relict new population of Ribes uva-crispa L. (Grossulariaceae) is found on Mount Carbonara (Madonie Mts., North-Central Sicily), which is several hundred kilometers away from the Central Apenninic and the South Mediterranean locations of its distribution range. R. uva-crispa shows a distribution similar to other taxa extending from the Euro-Asiatic area to the mountains of North Africa with disjunct populations on the main Sicilian reliefs (Madonie and Nebrodi Mts.), testifying ancient phytogeographical connections. This noteworthy record adds a new species – as well as a new genus and new family – to the vascular flora of Sicily. Based on the morphological characters, the population found is to be referred to Ribes uva-crispa L. subsp. austro-europaeum (Bornm.) Bech var. glanduligerum (Lindberg) Maire

Response Generation in Longitudinal Dialogues: Which Knowledge Representation Helps?

Longitudinal Dialogues (LD) are the most challenging type of conversation for human-machine dialogue systems. LDs include the recollections of events, personal thoughts, and emotions specific to each individual in a sparse sequence of dialogue sessions. Dialogue systems designed for LDs should uniquely interact with the users over multiple sessions and long periods of time (e.g. weeks), and engage them in personal dialogues to elaborate on their feelings, thoughts, and real-life events. In this paper, we study the task of response generation in LDs. We evaluate whether general-purpose Pre-trained Language Models (PLM) are appropriate for this purpose. We fine-tune two PLMs, GePpeTto (GPT-2) and iT5, using a dataset of LDs. We experiment with different representations of the personal knowledge extracted from LDs for grounded response generation, including the graph representation of the mentioned events and participants. We evaluate the performance of the models via automatic metrics and the contribution of the knowledge via the Integrated Gradients technique. We categorize the natural language generation errors via human evaluations of contextualization, appropriateness and engagement of the user

Incremental Object-Based Novelty Detection with Feedback Loop

Object-based Novelty Detection (ND) aims to identify unknown objects that do not belong to classes seen during training by an object detection model. The task is particularly crucial in real-world applications, as it allows to avoid potentially harmful behaviours, e.g. as in the case of object detection models adopted in a self-driving car or in an autonomous robot. Traditional approaches to ND focus on one time offline post processing of the pretrained object detection output, leaving no possibility to improve the model robustness after training and discarding the abundant amount of out-of-distribution data encountered during deployment. In this work, we propose a novel framework for object-based ND, assuming that human feedback can be requested on the predicted output and later incorporated to refine the ND model without negatively affecting the main object detection performance. This refinement operation is repeated whenever new feedback is available. To tackle this new formulation of the problem for object detection, we propose a lightweight ND module attached on top of a pre-trained object detection model, which is incrementally updated through a feedback loop. We also propose a new benchmark to evaluate methods on this new setting and test extensively our ND approach against baselines, showing increased robustness and a successful incorporation of the received feedback

Contribution to the knowledge of Mediterranean wetland vegetation: Lemnetea and Potamogetonetea classes in Western Sicily

The freshwater aquatic vegetation of the Lemnetea and Potamogetonetea classes in Western Sicily was surveyed and analyzed. 85 lakes and small pools were investigated collecting 147 phytosociological unpublished relev\ue9s to integrate the very scarce available data (only 3 relev\ue9s). By applying statistical analyses on abundances data and on the bases of physiognomy and dominant species, two alliances (Lemnion minoris and Stratiotion) and four different coenoses have been identify for the Lemnetea class; while 11 associations, assigned to two orders (Potamogetonetalia pectinati and Callitricho hamulatae-Ranunculetalia aquatilis) and four alliances (Potamogetonion, Nymphaeion albae, Ranunculion aquatilis and Ranunculion omiophyllo-hederacei) have been recognized for the Potamogetonetea class. A new association (Junco bufonii-Ranunculetum omiophylli ass. nov.) and a new subassociation (Ranunculetum peltati ranunculetosum rionii subass. nov.) have been proposed, whereas other six vegetation units were found to be new for the study area (Potamogetono-Ceratophylletum submersi, Potamogetonetum pusilli, Ranunculetum aquatilis, Ranunculetum peltati and Ranunculetum rionii, Lemno-Callitrichetum obtusangulae). For all the coenoses recognized, new insights on the floristic composition, syntaxonomy, synphiognomy, synecology and synchorology are reported, offering a reasoned overview of the aquatic vegetation of the western sector of the main Mediterranean island

Width of surface rupture zone for thrust earthquakes: implications for earthquake fault zoning

The criteria for zoning the surface fault rupture hazard (SFRH) along thrust faults are defined by analysing the characteristics of the areas of coseismic surface faulting in thrust earthquakes. Normal and strike–slip faults have been deeply studied by other authors concerning the SFRH, while thrust faults have not been studied with comparable attention. Surface faulting data were compiled for 11 well-studied historic thrust earthquakes occurred globally (5.4 ≤ M ≤ 7.9). Several different types of coseismic fault scarps characterize the analysed earthquakes, depending on the topography, fault geometry and near-surface materials (simple and hanging wall collapse scarps, pressure ridges, fold scarps and thrust or pressure ridges with bending-moment or flexural-slip fault ruptures due to large-scale folding). For all the earthquakes, the distance of distributed ruptures from the principal fault rupture (r) and the width of the rupture zone (WRZ) were compiled directly from the literature or measured systematically in GIS-georeferenced published maps. Overall, surface ruptures can occur up to large distances from the main fault ( ∼ 2150 m on the footwall and  ∼  3100 m on the hanging wall). Most of the ruptures occur on the hanging wall, preferentially in the vicinity of the principal fault trace ( >   ∼  50 % at distances  <   ∼  250 m). The widest WRZ are recorded where sympathetic slip (Sy) on distant faults occurs, and/or where bending-moment (B-M) or flexural-slip (F-S) fault ruptures, associated with large-scale folds (hundreds of metres to kilometres in wavelength), are present. A positive relation between the earthquake magnitude and the total WRZ is evident, while a clear correlation between the vertical displacement on the principal fault and the total WRZ is not found. The distribution of surface ruptures is fitted with probability density functions, in order to define a criterion to remove outliers (e.g. 90 % probability of the cumulative distribution function) and define the zone where the likelihood of having surface ruptures is the highest. This might help in sizing the zones of SFRH during seismic microzonation (SM) mapping. In order to shape zones of SFRH, a very detailed earthquake geologic study of the fault is necessary (the highest level of SM, i.e. Level 3 SM according to Italian guidelines). In the absence of such a very detailed study (basic SM, i.e. Level 1 SM of Italian guidelines) a width of  ∼  840 m (90 % probability from "simple thrust" database of distributed ruptures, excluding B-M, F-S and Sy fault ruptures) is suggested to be sufficiently precautionary. For more detailed SM, where the fault is carefully mapped, one must consider that the highest SFRH is concentrated in a narrow zone,  ∼ 60 m in width, that should be considered as a fault avoidance zone (more than one-third of the distributed ruptures are expected to occur within this zone). The fault rupture hazard zones should be asymmetric compared to the trace of the principal fault. The average footwall to hanging wall ratio (FW  :  HW) is close to 1  :  2 in all analysed cases. These criteria are applicable to "simple thrust" faults, without considering possible B-M or F-S fault ruptures due to large-scale folding, and without considering sympathetic slip on distant faults. Areas potentially susceptible to B-M or F-S fault ruptures should have their own zones of fault rupture hazard that can be defined by detailed knowledge of the structural setting of the area (shape, wavelength, tightness and lithology of the thrust-related large-scale folds) and by geomorphic evidence of past secondary faulting. Distant active faults, potentially susceptible to sympathetic triggering, should be zoned as separate principal faults. The entire database of distributed ruptures (including B-M, F-S and Sy fault ruptures) can be useful in poorly known areas, in order to assess the extent of the area within which potential sources of fault displacement hazard can be present. The results from this study and the database made available in the Supplement can be used for improving the attenuation relationships for distributed faulting, with possible applications in probabilistic studies of fault displacement hazard
