Konsep Diri Wanita Model Fashion Show di Pekanbaru

A woman\u27s life fashion show models synonymous with glamorous lifestyle, nightlife, and even sex. In order to meet the demands and lifestyle as a model, they often do things - negative things like, into prostitution "or being a mistress" This situation results in the emergence of a negative assessment of the community of women who worked as a model, even though it can not be in jendralisis. Departing from this condition researchers are interested to know how the woman\u27s self concept models fashion show in Pekanbaru. This study aims to determine the dimensions of the internal and external dimensions of the model woman fashion show in Pekanbaru.This study uses qualitative research with phenomenological approach. Subjects consisted of five informants, who were selected through key informant named mas Raymond as the supreme mentor administrators Putri Indonesia Riau representatives, using techniques snowball technique. The study used data collection techniques of observation, interviews, and research documentation. To achieve the validity of the data in this study, researchers used the extension of participation and triangulation. The research shows the internal dimensions of the model woman fashion show in Pekanbaru, self-identity that is a model woman, some of the informants came from poor families, life changed since the model works better established with the result being a mistress. Actors themselves that promiscuity and environmental influences make a drastic change. Self receiver is aware of the bad deeds, received negative comments from the public. Dimensions of the external female models fashion show in Pekanbaru. Physical self, perfect for the main requirement of a model. Moral ethical self, refusing to be grateful, not to close themselves to God. causing properties or characters that are easily affected by the surrounding environment . Self always perform imaging and lies. Self family , very close to the family , very supportive in the profession as a model . Social self is not arrogant if you meet someone who is known , friendly , nice , easy to make friends. But other things with friends in the profession (model ) , do have a sense of competition and jealousy

Quantum correlation games

A new approach to play games quantum mechanically is proposed. We consider two players who perform measurements in an EPR-type setting. The payoff relations are defined as functions of correlations, i.e. without reference to classical or quantum mechanics. Classical bi-matrix games are reproduced if the input states are classical and perfectly anti-correlated, that is, for a classical correlation game. However, for a quantum correlation game, with an entangled singlet state as input, qualitatively different solutions are obtained. For example, the Prisoners' Dilemma acquires a Nash equilibrium if both players apply a mixed strategy. It appears to be conceptually impossible to reproduce the properties of quantum correlation games within the framework of classical games

A Study on the Ability in Writing Narrative Text by the Second Year Students of SMA Negeri 1 Tualang Perawang

This decriptive research was conducted to find out the writing ability in narrative text. The sample of this research was 60 participants from the second year students of SMA Negeri 1 Tualang Perawang by using cluster random sampling technique. The instruments used in this research was writing test. The data were analyzed by calculating students' score individually and finding out the mean score by using SPSS version 23.0. The data were presentated by using table and bar graph. The researche findings showed that the students's writing ability was in Poor Category (39.12). So, it was suggested that the students should be more active in taking part in writing activities not only during learning activities in the classroom but also outside the classroom. Then, teacher need motivate the students to do more practice in writing esspecially in narrative text

Faktor-Faktor Produksi yang Berpengaruh dalam Usahatani Cengkeh di Desa Puulemo Kecamatan Lembo Kabupaten Konawe Utara

This study aims to determine the influence of clove farming production factors in the village of Puulemo Kecamatan Lembo District Konawe Utara. The data collected in this study is using primary data and secondary data primary data obtained from direct interviews with farmers by using questionnaires. The sampling method is simple random sampling, with the number of farmers as many as 60 samples. The analysis used in this study is to use Cobb-Douglas function analysis to make it easier to make guesses then the equation is converted into a linear form. Independent variable of labor, fertilizer and per hectare land area The results showed that labor variable (X1) and fertilizer (X2) together and significantly effect on clove production in Puulemo Village Kecamataan Lembo regency of Konawe Utara at a level of α =0,0

Analyzing three-player quantum games in an EPR type setup

We use the formalism of Clifford Geometric Algebra (GA) to develop an analysis of quantum versions of three-player non-cooperative games. The quantum games we explore are played in an Einstein-Podolsky-Rosen (EPR) type setting. In this setting, the players' strategy sets remain identical to the ones in the mixed-strategy version of the classical game that is obtained as a proper subset of the corresponding quantum game. Using GA we investigate the outcome of a realization of the game by players sharing GHZ state, W state, and a mixture of GHZ and W states. As a specific example, we study the game of three-player Prisoners' Dilemma.Comment: 21 pages, 3 figure

Revisiting special relativity: A natural algebraic alternative to Minkowski spacetime

Minkowski famously introduced the concept of a space-time continuum in 1908, merging the three dimensions of space with an imaginary time dimension $i c t$, with the unit imaginary producing the correct spacetime distance $x^2 - c^2 t^2$, and the results of Einstein's then recently developed theory of special relativity, thus providing an explanation for Einstein's theory in terms of the structure of space and time. As an alternative to a planar Minkowski space-time of two space dimensions and one time dimension, we replace the unit imaginary $i = \sqrt{-1}$, with the Clifford bivector $\iota = e_1 e_2$ for the plane that also squares to minus one, but which can be included without the addition of an extra dimension, as it is an integral part of the real Cartesian plane with the orthonormal basis $e_1$ and $e_2$. We find that with this model of planar spacetime, using a two-dimensional Clifford multivector, the spacetime metric and the Lorentz transformations follow immediately as properties of the algebra. This also leads to momentum and energy being represented as components of a multivector and we give a new efficient derivation of Compton's scattering formula, and a simple formulation of Dirac's and Maxwell's equations. Based on the mathematical structure of the multivector, we produce a semi-classical model of massive particles, which can then be viewed as the origin of the Minkowski spacetime structure and thus a deeper explanation for relativistic effects. We also find a new perspective on the nature of time, which is now given a precise mathematical definition as the bivector of the plane.Comment: 29 pages, 2 figure
