Group Invariant Global Pooling

Much work has been devoted to devising architectures that build group-equivariant representations, while invariance is often induced using simple global pooling mechanisms. Little work has been done on creating expressive layers that are invariant to given symmetries, despite the success of permutation invariant pooling in various molecular tasks. In this work, we present Group Invariant Global Pooling (GIGP), an invariant pooling layer that is provably sufficiently expressive to represent a large class of invariant functions. We validate GIGP on rotated MNIST and QM9, showing improvements for the latter while attaining identical results for the former. By making the pooling process group orbit-aware, this invariant aggregation method leads to improved performance, while performing well-principled group aggregation

EFEKTIVITAS PENDAMPINGAN DAN PEMBERIAN MAKANAN TAMBAHAN (PMT) PADA ANAK PENDERITA STUNTING DI KELURAHAN SEMANGGI PROVINSI JAWA TENGAH

Abstrak: Kelurahan Semanggi memiliki total anak penderita stunting tertinggi di Kota Surakarta Jawa Tengah yaitu sebesar 18,5 %. Tercatat terdapat 9 anak penderita stunting yang mayoritas faktor penyebabnya antara lain tingkat kemiskinan yang tinggi, lingkungan yang kurang bersih, dan kurangnya pengetahuan mengenai gizi penunjang pertumbuhan anak. Salah satu solusi yang dapat dilakukan adalah dengan pemberian makanan tambahan (PMT) dan sosialisasi. Metode sosialisasi door to door digunakan dalam program ini, dimana anggota pengabdi mendatangi rumah keluarga yang memiliki anak penderita stunting. Kegiatan ini bertujuan untuk membantu meningkatkan tumbuh kembang anak yang terlanjur mengalami stunting. Hasil pelaksanaan kegiatan PMT yang dilakukan sebanyak tiga kali menunjukkan terjadi peningkatan berat badan secara bertahap. Hasil kegiatan juga menunjukkan terjadinya peningkatan kesadaran orang tua terhadap gizi anak yang harus terpenuhi yaitu sebesar hampir 100%. Melalui kegiatan sosialisasi dan pemberian makanan tambahan ini, dapat membantu Dinas Kesehatan Kota dalam mengedukasi masyarakat supaya penanganan stunting khususnya di Kelurahan Semanggi, Kecamatan Pasar Kliwon Kota Surakarta dapat segera teratasi.Abstract: Semanggi Village has the highest total stunting children in Surakarta City of Central Java which is 18.5%. There are 9 children with stunting, the majority of which are the causes, including high poverty rates, a less clean environment, and lack of knowledge about nutrition supporting child growth. One solution that can be done is by supplemental feeding (PMT) and socialization. Door to door method is used in this program, where members visit the homes of families who have stunted children. This activity aims to help increase the growth and development of children who have stunting. The results of the implementation of PMT activities carried out three times showed a gradual increase in weight. The results of the implementation of PMT activities carried out three times showed a gradual increase in weight. The results of the activity also showed an increase in parental awareness of child nutrition that must be fulfilled by almost 100%. Through this socialization and supplemental feeding activities, it can help the City Health Office in educating the community so that the handling of stunting, especially in Semanggi Village, Kliwon Market District of Surakarta City can be resolved immediately

Manejo terapéutico y comorbilidades del paciente con dependencia a opiáceos, en programa de terapia sustitutiva: Estudio PROTEUS

Resumen Objetivo Analizar la necesidad de realizar un estudio epidemiológico de pacientes dependientes de opiáceos centrado en conocer más sus tratamientos, comorbilidades médicas y psiquiátricas. Material y métodos Se examinó la necesidad de tener datos disponibles en nuestro medio sobre el manejo clínico de estos pacientes, el tipo de tratamiento y las posibles comorbilidades. No existen datos completos, representativos de los pacientes españoles. Por ello se seleccionó una muestra representativa a nivel nacional, a partir de la población de pacientes dependientes de opiáceos en programas de mantenimiento con agonistas opiáceos que acudían a los centros asistenciales de drogodependencias. Resultados El estudio final incluyó una población representativa de 624 pacientes dependientes a opiáceos en programas de mantenimiento con agonistas, procedentes de 74 centros de asistencia al dependiente de opiáceos de toda España. Conclusiones Se conocen poco los datos sobre la comorbilidad psicopatológica y médica y los tratamientos farmacológicos en pacientes dependientes de opiáceos. Es necesario realizar un estudio epidemiológico amplio que actualice la realidad de la práctica clínica habitual del paciente dependiente de opiáceos en España (manejo terapéutico, comorbilidades, etc.) valore la gravedad de su adicción, la repercusión sobre el tipo de tratamiento, la presencia de patología dual y las repercusiones médicas. Abstract Background The purpose of this study was to analyze the need for an epidemiological study of opiate-dependent patients aiming to improve the knowledge about their treatment and medical and psychiatric comorbidities. Matherial and methods Data on clinical management, treatment type, and comorbidities in Spain were examined. There are no comprehensive data, representative of the Spanish patients. Therefore, a national representative sample was selected from opiate-dependent patients ongoing replacement therapy programs, attending care centers for opiatedependent patients. Results The representative sample included 624 opiate-dependent patients ongoing opiate replacement therapy programs from 74 drug-dependent rehabilitation centers in Spain. Conclusions Data on therapeutic management and psychiatric and medical comorbidities in opiate-dependent patients are not well known. There is a need for a comprehensive epidemiological study to update the reality of clinical practice of opioiddependent patients in Spain (therapeutic management, comorbidities, etc.) assessing the severity of their addiction, the impact on the type of treatment, the presence of dual pathology and medical implications

Bayesian model selection and classification: application to brain tissues through T distribution

A Bayesian procedure for model selection, parameter estimation and classification, using models of non-orthogonal basis functions, is applied to the problem of T2 decay rate distributions in brain tissues. The feasibility of generating reliable synthetic images of tissue-classified pixels is examined. The work determines, for the first time, the Bayesian probability of existence of short (5-15ms) T2 component in the brain tissues, and found it to be higher than 99% for all white matter tissues and higher than 80% for all gray matter tissues except Cortical Gray . The probability of having no more than three components of decaying exponents in the Ti distributions of the brain tissues, is found to be higher than 90% for all the tissues. We arrive to these findings through the use of models which are parameterized by highly coupled parameters, and the use of multi-dimensional search in the space of these models.Science, Faculty ofPhysics and Astronomy, Department ofGraduat

Attachment theory as a conceptual framework for risk pathways in non-suicidal self-injury

This thesis examines possible risk pathways for non-suicidal self-injury using attachment theory as a conceptual framework. It proposes a model with three pathways for self-injury, which are initiated by the distal risk factors of insecure attachment to the mother, the father and peers. The research suggests that from this initial point the pathways are then developed by means of proximal risk factors: the first via stressful life events and emotional distress; the second through low self-efficacy and non-productive coping strategies and the third pathway via emotion deregulation and impulsivity. The study explores the model by empirically testing the proposed risk pathways for self-injury in young people in the community. Participants were 275 young people (aged 13-26) recruited from secondary schools, youth groups and one large university, who completed a self-report pencil and paper questionnaire. The self-report instruments were used to measure the variables of non-suicidal self-injury, self-injury motivation, attachment to parents and peers, stressful life events, depressive, anxiety and stress symptoms, self-efficacy, coping strategies, emotion regulation and impulsivity. For each of the three proposed pathways, separate multiple regressions were performed to examine the relationship between the distal risk factors of attachment to the mother, father and peers, and self-injury. The final step involved examination of the relationship between attachment and self-injury to determine any possible mediation by the proximal risk factors. The study reports on self-injury in an Australian non-clinical sample of young people. Twenty-two per cent of the sample participants reported at least one episode of self-injury. Mean age for the first episode of self-injury was 13.37 years and for the last episode 15.82 years. Of those reporting self-injury, 66 per cent told someone about their behaviour, mostly their friends, and 16.39 per cent visited a medical practitioner. The most frequent motivation for self-injury, described by 36.7 per cent of those who self-injured, was to be distracted from emotional pain by experiencing physical pain. The study reveals that the relationship between maternal attachment and self-injury was fully mediated by stressful life events, depressive symptoms, low self-efficacy and non-productive coping strategies. The relationship between paternal attachment and self-injury was partly mediated by these proximal factors. The relationship between peer attachment and self-injury was partly mediated by the above proximal factors and also by impulsivity. Unexpectedly, emotion deregulation was not related to self-injury. A number of implications are suggested by the findings. These include preparing children at the onset of adolescence to develop effective coping strategies in stressful conditions; providing information to principals, counselors and teachers on factors that may be involved in pathways to self-injury; and familiarizing adolescent leaders with resources on how to support other adolescents at risk. Clinical implications include the need for a focus among self-injuring individuals and their parents on strengthening the security of the attachment relationship: for example, by working on being open to, and aware of, negative emotions. This holds out the possibility for young people and parents to become more fully attuned to the whole spectrum of feelings, thereby facilitating more effective responses to distress.
