Scaling Up: The Validation of Empirically Derived Scheduling Rules on NVIDIA GPUs
Embedded systems augmented with graphics processing units (GPUs) are seeing increased use in safety-critical real-time systems such as autonomous vehicles. The current black-box and proprietary nature of these GPUs has made it difficult to determine their behavior in worst-case scenarios, threatening the safety of autonomous systems. In this work, we introduce a new automated validation framework to analyze GPU execution traces and determine if behavioral assumptions inferred from black-box experiments consistently match behavior of real-world devices. We find that the behaviors observed in prior work are consistent on a small scale, but the rules do not stretch to significantly older GPUs and struggle with complex GPU workloads.Bachelor of Scienc
Simultaneous Multithreading Applied to Real Time (Artifact)
Existing models used in real-time scheduling are inadequate to take advantage of simultaneous multithreading (SMT), which has been shown to improve performance in many areas of computing, but has seen little application to real-time systems. The SMART task model, which allows for combining SMT and real time by accounting for the variable task execution costs caused by SMT, is introduced, along with methods and conditions for scheduling SMT tasks under global earliest-deadline-first scheduling. The benefits of using SMT are demonstrated through a large-scale schedulability study in which we show that task systems with utilizations 30% larger than what would be schedulable without SMT can be correctly scheduled. This artifact includes benchmark experiments used to compare execution times with and without SMT and code to duplicate the reported schedulability experiments

Infant feeding as a transgressive practice in the context of HIV in the UK: A qualitative interview study
HIV transmission risk via breastfeeding is greatly reduced by antiretroviral therapy but is not zero. Current UK guidelines recommend exclusive formula feeding; however, women can breastfeed if they meet certain criteria. We examine the narrative accounts of mothers with HIV (pregnant or recently given birth) who navigated divergent cultural and national policy norms regarding infant feeding.
Mothers with HIV, the majority of whom in the UK are of Black African ethnicity, face a complex decision regarding infant feeding, which has implications for their sense of identity, belonging and citizenship. While the UK has one of the lowest breastfeeding rates globally, breastfeeding is normalised across African and Asian cultures. However, HIV remains stigmatised and formula feeding could signal one's HIV-positive status. Our participants made difficult trade-offs to mitigate the variety of threats they faced, and both feeding options (breast or formula) felt transgressive, with immense hazards involved for these intersectionally-disadvantaged women

Analisis Faktor Determinan Yang Mempengaruhi Pelaksanaan Budaya Keselamatan Pasien di Rumah Sakit Umum Daerah Mgr. Gabriel Manek, Svd Atambua
Budaya keselamatan pasien merupakan produk dari nilai, sikap,
kompetensi dan pola perilaku individu dan kelompok yang menentukan komitmen
dan kemampuan suatu budaya organisasi pelayanan kesehatan terhadap
program keselamatan pasien. Dampak dari budaya keselamatan pasien yang
kurang di rumah sakit adalah menurunnya tingkat kepercayaan masyarakat
terhadap pelayanan kesehatan. Organisasi kesehatan dunia mengestimasi
bahwa di Asia orang menerima lebih dari 5 kali injeksi/tahun dan 50% dari
tindakan injeksi tersebut tidak aman. Sekitar 4% pasien mengalami adverse
event selama dirawat di rumah sakit, 70% berakhir dengan kecacatan
sementara, sedangkan 14% berkahir dengan kematian. Sedangkan Institute of
Medicine mencatat sebanyak 44.000-98.000 orang meninggal per tahunnya di
Amerika Serikat yang disebabkan oleh kesalahan medis. Dan untuk Indonesia
dalam rentang waktu 2006-2011 Komite Keselamatan Pasien Rumah sakit
melaporkan adanya sejumlah 877 insiden terkait keselamatan pasien. WHO
mengembangkan empat kategori faktor yang sangat berhubungan dengan
penyebab insiden keselamatan pasien yaitu : kategori faktor budaya organisasi,
kategori faktor kerja tim, kategori faktor individu, dan kategori faktor lingkungan
kerja.
Tujuan dari penelitian ini adalah untuk mengetahui faktor determinan yang
mempengaruhi pelaksanaan budaya keselamatan pasien di Rumah sakit Umum
Daerah Mgr. Gabriel Manek SVD Atambua. Penelitian ini merupakan rancangan
penelitian kuantitatif mengunakan desain cross sectional yang dianalisis dengan
regresi linear berganda. Responden pada penelitian ini sebanyak 127
responden.
Hasil penelitian, pada univariat di dapatka hasil distribusi frekwensi budaya
organisasi, tim kerja, individu, lingkungan kerja dan budaya keselamatan pasien
berada pada kategori baik, ini menggambakan semakin tinggi budaya organisasi,
kerja tim, individu dan lingkungan kerja maka akan semakin baik budaya
keselamatan pasien di Rumah sakit. Uji pearson corelation diperoleh hasil
hubungan budaya organisasi dengan budaya keselamatan pasien p=0,000 dan
memiliki hubungan yang kuat dengan nilai corelation coefision 0,829. Hubungan
kerja tim dengan budaya keselamatan pasien p=0,000 dan memiliki hubungan
yang kuat dengan nilai corelation coefision 0,868. Hubungan Individu dengan
budaya keselamatan pasien p=0,000 dan memiliki hubungan yang kuat dengan
nilai correlation coefficient 0,856. Hubungan lingkungan kerja dengan budaya
keselamatan pasien p=0,000 dan memiliki hubungan yang kuat dengan nilai
correlation coefficient 0,863. Ini menjelaskan bahwa budaya keselamatan pasien
merupakan upaya untuk meningkatkan ketepatan identifikasi pasien,
peningkatan komunikasi yang efektif, peningkatan keamanan obat, tepat lokasi
prosedur operasi, pengurangan risiko infeksi terkait pelayanan kesehatan dan
pengurangan risiko pasien jatuh melalui budaya organisasi, kerja tim, individu
dan lingkungan kerja baik. Sedangkan analisis multivariat menggunakan uji
regresi linear berganda didapatkan persamaan Y = 40,842 + 1,007(Faktor Kerja
tim) + 1,042 (Faktor Lingkungan kerja). Nilai constanta positif menunjukkanviii
pengaruh positif variabel independen yaitu variabel kerja tim dan variabel
lingkungan kerja. 1,007 merupakan nilai koefisien regresi variabel kerja tim
terhadap budaya keselamatan pasien, yang artinya jika variabel kerja tim
mengalai kenaikan satu satuan maka budaya keselamatan pasien akan
mengalami peningkatan 1,007. Dan 1,042 merupakan nilai koefisien regresi
variabel lingkungan kerja terhadap budaya keselamatan pasien, yang artinya jika
variabel lingkungan kerja mengalai kenaikan satu satuan maka budaya
keselamatan pasien akan mengalami peningkatan 1,042.
Terdapat hubungan yang signifikan antara faktor budaya organisasi, kerja
tim, individu dan lingkungan kerja terhadap budaya keselamatan dan faktor yang
paling dominan mempengaruhi budaya keselamatan pasien di Rumah sakit Mgr.
Gabriel Manek, SVD Atambua berdasarkan pemodelan regresi linear adalah tim
kerja. Kerja tim akan menjadi penentu lancar tidaknya suatu organisasi. Interaksi
dalam tim berpengaruh terhadap prilaku anggota dalam berkomunikasi dan
terbuka dalam mengungkapkan kesalahan yang terjad

Representations of the homosexuality in francophones literatures : between insults, silence, transvaluation and sexuality. areas of 'Le Flamant noir' of Berthrand Nguyen Matoko, '39 rue de Berne' (Max Lobe), 'Chuchote pas trop' and 'Portrait d'une jeu
En choisissant de travailler sur les représentations de l’homosexualité dans les pays francophones d’Afrique subsaharienne, nous poursuivions trois objectifs à portée de main. S’insurgeant contre le silence de plusieurs universitaires dudit continent à aborder la thématique de l’homosexualité dans leurs travaux scientifiques, faire de celle-ci notre réflexion s’est donc imposé à nous de façon impérative. En effet, notre premier objectif (épistémologique) était de s’intéresser à cette thématique qui demeure encore un champ quasi inexploré et inexploité en littérature en milieux francophones d’Afrique afin de réfléchir sur les problématiques que soulève cette sexualité si prégnante aujourd’hui. En d’autres termes, le désintéressement ou le manque d’intérêt du plus grand nombre a produit en nous un effet sans doute doublé et dont l’aboutissement de ce travail peut prétendre être l’écho. Signalons que si les œuvres de fictions abondent il n’en est pas ainsi des travaux scientifiques sur le sujet. L’autre but visé, cette fois-ci pragmatique, consistait à infirmer l’idée selon laquelle l’homosexualité serait une sexualité exogène à l’Afrique. Une conception qui rend plus mal à l’aise les personnes homosexuelles qui se sentent mises à part à cause de leur sexualité. Comme nous l’avons amplement montré à la lumière des travaux de Charles Gueboguo, l’homosexualité est transculturelle et donc elle a toujours existé au sein de plusieurs peuples africains. En revanche, son questionnement actuel n’est pas celui que connurent les sociétés passées. Les mœurs changent avec le temps, les hommes y compris. C’est donc une conviction pour nous de (re)donner l’estime de soi, la confiance et la considération à ces personnes marginalisées sexuellement et/ou identitairement. Ce faisant, nous avons mis l’accent sur l’acceptation, l’affirmation et la représentation de soi, de son homosexualité. Le dernier objectif est beaucoup plus personnel et il voudrait satisfaire une curiosité intellectuelle. Pourquoi cette sexualité suscite-t-elle autant de débats de nos jours, divise-t-elle des familles ou des foyers dans certains pays, pourtant si insignifiante dans l’Antiquité grecque ? L’homosexualité est-elle seulement un acte sexuel entre deux ou plusieurs personnes de même sexe ou va-t-elle au-delà de la génitalité ? Des interrogations que nos nombreuses lectures et surtout nos analyses ont permis de comprendre autrement qu’avec un regard judicateur ou une attitude intolérante envers les personnes homosexuelles.By choosing to work on representations of homosexuality in French-speaking sub-Saharan African countries, we pursued three goals at our fingertips. Insurgency against the silence of several African scholars to address the theme of homosexuality in their scientific work, to make it our reflection has therefore imposed itself on us imperatively. Indeed, our first objective (epistemological) was to take an interest in this theme, which still remains an almost unexplored and untapped field of literature in French-speaking Africa, in order to reflect on the issues raised by this highly pregnant sexuality today. In other words, the disinterest or the lack of interest of a large number (of scholars) has undoubtedly drove in us an extra motivation whose result of this work can claim to be the echo. It should be noted that while fiction works abound, this is not the case for scientific work on the subject. The other aim, this time pragmatic, was to refute the idea that homosexuality is an exogenous sexuality to Africa. An idea that makes gay people more uncomfortable and feel apart because of their sexuality. As we have amply demonstrated in the light of Charles Guebogo's work, homosexuality is transcultural and therefore it has always existed among many African peoples. However, its current questioning is not that of past societies. Morals change with time, including men. It is therefore a conviction for us to (re)store self-esteem, trust and consideration to those people who are marginalized because of their sexual orientation. In doing so, we have emphasized acceptance, affirmation and self-representation of one's homosexuality. The last goal is much more personal and it aims at satisfying an intellectual curiosity. Why does this sexuality arouse so much debate these days, divide families or homes in some countries, yet so insignificant in Greek antiquity? Is homosexuality only a sexual act between two or more people of the same sex or does it go beyond genitality? Queries that our many readings and above all our analyzes have allowed to understand otherwise than with a look judge or intolerant attitude towards homosexuals
