Comparison of Transfer Learning Using VGG16, MobileNetV2, and ResNet50 for Pornography Image Detection
No full textThe rapid growth of digital technology is vital for the Indonesian Scout to reach and interact with its members. The National Indonesian Scout (Kwarnas) uses the “Ayo Pramuka” social media application to support this. However, such platforms risk exposing users, especially teenagers, to harmful content like pornography. This research applies Computer Vision and Transfer Learning Convolutional Neural Networks (CNNs) to detect pornographic images automatically. The objective is to identify the CNN model (VGG16, MobileNet V2, ResNet 50) with the highest detection accuracy and determine the impact of color space preprocessing. The method includes two stages first, image preprocessing by converting RGB images to HSV and YCbCr second, feature extraction using pre-trained CNNs with freezing and fine-tuning. A dataset of 4060 images was used for training and testing. Without preprocessing, VGG16 achieved the best accuracy of 99.01%. When RGB images were converted to HSV, ResNet 50 produced the highest accuracy of 99.51%. The findings show that combining color space transformation and Transfer Learning CNN significantly improves pornographic content detection in the “Ayo Pramuka” Application, enhancing safe digital engagement for Indonesian Scouts
A scaling-relation for disc galaxies: circular-velocity gradient versus central surface brightness
No full textFor disc galaxies, a close relation exists between the distribution of light and the
shape of the rotation curve. We quantify this relation by measuring the inner circular-
velocity gradient dRV (0) for spiral and irregular galaxies with high-quality rotation
curves. We find that dRV (0) correlates with the central surface brightness μ0 over
more than two orders of magnitude in dRV (0) and four orders of magnitudes in μ0.
This is a scaling-relation for disc galaxies. It shows that the central stellar density of a
galaxy closely relates to the inner shape of the potential well, also for low-luminosity
and low-surface-brightness galaxies that are expected to be dominated by dark matter.
Key words: dark matter – galaxies: kinematics and dynamics – galaxies: structure
Macroeconomic adjustment, stabilization, and growth in reforming socialist economies : analytical and policy issues
No full textCurrent attempts at reform in Eastern European countries raise important issues of macroeconomic management in the transition from central planning to a market or mixed economy. This paper develops simple models, reviews empirical evidence and discusses policy issues associated with traditional socialist economies and those undergoing reform. Those issues involve inflation, growth, money overhang, disequilibrium in goods and labour markets and interactions between stabilization and growth.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Economic Stabilization,Municipal Financial Management
Who is going to save the final girl? the politics of representation in the films halloween and the silence of the lambs
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Inglês: Estudos Linguísticos e Literários, Florianópolis, 2014Abstract: This dissertation aims at analyzing female representations in two film productions of the North American horror cinema, specifically of its subgenre slasher films, namely Halloween, directed by John Carpenter (1978) and The Silence of the Lambs, directed by Jonathan Demme (1991). My main theoretical framework is film, representation, gender, feminist and queer theories (Butler, 1990, 1993; Clover, 1989; Dika, 1985, Halberstam, 1995; Hall 1973, 1997; Mulvey, 1975, 1981; 2006; Rockoff, 2006; Weedon, 1995). My hypothesis is that the figure of the final girl, in the two films selected for analysis, is not progressive as suggested by the author Carol Clover in her work Men, Women and Chainsaws (1989). On the contrary, the two female characters are represented, in the narrative, as subjugated by the patriarchal system that has been conventionalized in the slasher subgenre. In order to provide arguments for my hypothesis, I analyze general aspects of both form and content of the two films, as well as specific scenes, using the cinematic elements of mise-en-scène, props, characterization, editing and lighting in order to obtain relevant results for my research.Esta tese de doutorado objetiva analisar as representações femininas em duas produções cinematográficas do cinema de horror Norte-americano, especificamente do seu subgênero slasher films, intituladas Halloween, dirigido por John Carpenter (1978) e The Silenceof the Lambs, dirigido por Jonathan Demme (1991). Para tal análise, eu utilizo como referencial teórico as teorias de estudos de cinema, representação, gênero, feministas e queer (Butler, 1990, 1993; Clover, 1989; Dika, 1985; Halberstam, 1995; Hall, 1973, 1997; Halberstam, 1995; Mulvey, 1975; 1981; 2006; Rockoff, 2006; Weedon, 1995) para compor os meus argumentos. A minha hipótese consiste no fato de que a figura da final girl não é inovadora como sugere a autora Carol Clover em sua obra Men, Women and Chainsaws (1989). Ao contrário, a personagem feminina é representada na narrativa como subjugada pelo sistema patriarcal que se convencionou em filmes do gênero. Para a investigação da minha hipótese, foram feitas análises gerais dos filmes propostos, tanto considerando suas formas quanto conteúdos, bem como a de cenas específicas, utilizando-se dos elementos de cinema tais como mise-èn-scene, elementos de cena, caracterização de personagens, edição e luz a fim de obter resultados relevantes para a minha pesquisa
En-gendering theatre in Eritrea : the roles and representations of women in the performing arts
No full textThis thesis is a first attempt at writing a modern theatre historiography of Eritrea, with emphasis on the roles and representations of women. It covers a period of some fifty years, from the late 1930s to 1991, the year of the country's de facto independence. The study is divided into three major sections; Part One providing the context of theatre in Eritrea, Part Two dealing with the emergence of modern Eritrean theatre arts, and Part Three covering the rise of the fighter performing arts during the thirty-year liberation struggle against Ethiopia.
After an introduction to Eritrean history and theatre arts as well as the theoretical framework of the study, Chapter 1 examines women's roles and representations in Eritrean societies and selected traditional performing arts as the
matrix onto which modern performance practices are built.
Chapter 2 starts with a portrayal of early urban women performers in the late 1930s and early 1940s as singers and krar-players in local drinking houses, followed by the gradual expansion of Eritrean theatre arts under the British
Military Administration. Thereafter the establishment of three well-known Eritrean theatre associations is examined, with Chapter 3 focusing on the Asmara Theatre Association, Mahber Theatre Asmara, whose work was eventually brought to a halt by the rise of the Ethiopian Derg regime. An investigation into the cultural troupes of the two liberation movements, the Eritrean Liberation Front
(ELF) and the Eritrean People's Liberation Front (EPLF) is dealt with in Part Three.
Chapter 4 outlines theatre work in the ELF, while Chapters 5-7 present details of EPLF performing arts. Chapter 5 begins with early performance activities until
the strategic retreat in 1978/79, followed by Chapter 6 with an analysis of drama work after the reorganisation of the Division of Culture. Chapter 7 covers theatre
activities in mass organisations and supporting departments and outlines cultural developments during the final years of the liberation war. In conclusion, major trends and directions in post-independence Eritrean theatre arts are summarised as they continue to negotiate recent socio-political problems and developments
"Joining the End to the Beginning" Divine Providence and the Interpretation of Scripture in the Teaching of Irenaeus, Bishop of Lyons
No full textIn this dissertation, the author argues that Irenaeus, Bishop of Lyons in the second century, reads the scriptures as the living proclamation of the Creator by which he creates and forms human flesh and blood. The scriptural narrative originates in God’s creation of all things ex nihilo and traces the movement of humanity toward its eschatological perfection in the incarnate, crucified, and risen Christ. Thus, the author argues that, for Irenaeus, the scriptures are as anthropological as they are theological. The biblical narrative possesses a continuity that is rooted in the substance of the human body. The very body that was created out of the dust in Adam, preserved from the flood in Noah, catechized by the law in Abraham and Moses, and became accustomed to the Spirit in the prophets is assumed by the Son of God from the Virgin Mary, crucified on the tree of the cross, and raised from the grave. The author maintains that Irenaeus views the scriptures as a single narrative describing precisely that flesh and blood given at the eucharistic altar in the fellowship of the church. Irenaeus reads the scriptures, not only in an intimate relationship with the creation of all things in the beginning and their recapitulation in Christ, but also in accord with an ecclesial dimension. The biblical narrative describes the identity of the baptized, who are joined to the body of Jesus through the baptismal and eucharistic life of the church. From this perspective, the author insists that the meaning of the scriptures, for the second century bishop, is not merely rational, moral or mystical, but truly ontological
The challenge of feminism in Kenya : towards an Afrocentric worldview
No full textThis study deals with African women's literature, and specifically creative writing by Kenyan women, in the context of feminism and Afrocentricity. In the words of Obioma Nnaemeka (1995) critics of African women's literature have tended to rename, misname or silence women's voices in an attempt to make them fit into a feminist! Afrocentricity either or mould. This thesis argues that when attention is paid to African women
themselves, and the cultures from which and within which they write, it is clear that they embrace both feminism and Afrocentricity. By feminism I refer to African women's vision and activism for sexual equality and women's liberation while by Afrocentricity I am thinking of their commitment and pride in their African cultures and
traditions.
The first chapter argues that Kenyan women, in pre-colonial, colonial and post-colonial times, have been active and voiced in their stance against oppression of any kind. In the second chapter, I explore the relationship between feminism and Afrocentricity in a wider sense. I pay attention to the ways in which the two concepts have manifested themselves in Africa and her Diaspora as well as in the western world. In chapter three, domestic violence, rape, poverty, and a gender insensitive legal and judiciary
system are the dominant issues of concern to short stories writers from Kenya. In the fourth chapter, Ogot is seen as a liberal Afrocentric feminist in her call for African
women to create room for themselves within African systems of thought and practice. Chapter five, on Oludhe Macgoye, argues that to be Afrocentric is cultural rather than
racial. In Chapter six Rebeka Njau and Margaret Ogola are seen as Afrocentric while Tsitsi Dangarembga and Alice Walker are seen as Eurocentric. The thesis concludes that feminism in practice is not necessarily an occidental phenomenon. An African woman writer can be both feminist and Afrocentric
Experience and everyday environment: a group reflective strategy
No full textThe distinctiveness of this thesis lies in its use of Group and Researcher Reflection. It is a responsive and experiential study, which has two main aims: to explore the phenomenon, experience in the everyday environment, and to develop an appropriate method. The study centres round Group Reflection, which consists of a small group of local residents (in Ushaw Moor, Co Durham), who met regularly over a year, to reflect together. They met to explicate and explore their experience, particularly heightened experience, of their everyday environment, and together to recognise themes, and so reveal, develop and share their understanding. The group collected their themes under three general headings: nature, buildings and people. A report summarising this Group Reflection was produced with the group. The whole of the Group Reflection forms the basis for subsequent Researcher Reflection. This seeks alternative orderings and interpretation of the material explicated, themes and experiences, and considers their relationship to the wider literature on environmental experience. A number of alternative themes, or gatherings, are suggested: looking language, social concept, ordering regimes, person-environment engagement. Then, the concepts experience, place and dwelling are explored in the context of everyday environment, and a number of speculations are made about the possible changing nature of dwelling. The study is inspired by Phenomenology, and therefore seeks to allow the phenomenon to speak of itself: through those who have direct experience of it, and it hopes to take into account the essential entanglement of what is studied with those who study. Finally, it seeks to encourage readers to continue the reflective journey into their own exploration of experience in the everyday environment
Mapping transference : problems of African literature and translation from French into English
No full textAlthough a number of African literary works have been
translated from French into English since the middle of this
century, research and debate on their translation has remained
scanty, fragmentary, and scattered in diverse learned journals
and other short publications. This thesis seeks to broaden the
scope of research by mapping out aspects of transference in
translation in terms of analysis and transfer strategies that
have been, or could be, used. A selection of major translated
works have been compared with their originals, to give textual
examples indicative of transfer strategies.
Current issues in African literature as well as typical
features of the literature in French and English have been
explored in order to examine differences between them and English
and French literatures. The implications of these differences (at
the levels of content, cultural setting, peculiar use of English
and French, and the target audience) for translation are
considered, and a brief historical survey of the translation of
African literature provides insights into how translators have
approached, and continue to approach, literary texts as well as
cope with their target readership. Furthermore, dominant trends
in literary translation studies (mainly in the West) are explored
to determine if, and in what ways, they relate to translation
studies in Africa.
The analysis of transfer strategies focuses on the
distinctive features of francophone African literary texts,
drawing on relevant Western literary translation theories and
models, on African literary theory and criticism, as well as on
other disciplines likely contribute to an informed understanding
of the texts. Finally, a case study applies the analysis to a
text which is translated, and transfer strategies discussed
