Problems in Protection of Information in a Multiuser On-Line System

The file system for the Moore School Problem Solving Facility of the University of Pennsylvania provides multiple files for various users and allows users to store, retrieve and update information in the files. The working environment when using the file system is on-line, multiple-access and real time. In this kind of environment there exists problems which do not arise in a batch process or in a single-access online environment. One of the problems that arises in using a file system in such an environment is that whenever a user makes changes in a particular file, he may cause other users, who are simultaneously accessing the same file to obtain erroneous information. The objective of this thesis is to provide a solution to the above problem

Swiping Your Life Away Failing to find love through Dating Apps

This essay focuses on examining the dating experience and interactions in the age of digital technology, specifically where social disempowered users of dating applications tend to reinforce systemic social oppression. This research draws from literature about communication ethics, critical theory studies, digital media studies and includes personal observations and experiences. Even though some apps have allowed minorities; the LGBTQ community, people of color (POC) and other groups, to interact in a platform where they share common interests, there are still some dating apps which are more mainstream. Dating within the same platform where ethical communication and intent has been swayed to a hook up culture online where people run high risks of safety and damage communication ties with other potential partners. Through meeting with strangers, the potential for physical abuse rises and communication strains are at a high rate through the use of dating apps. Besides the communication and personal risks aspects that face disenfranchised communities, I also highlight in this paper the dangers of safety and privacy issues associated with location- based geosocial networking smartphone applications also known as “GSN apps” (Rice et al 1) and the ethical implications of data mining. My research process includes peer review articles that address angles of experience and risk from different minority groups as well as the general public. I examine studies about particular apps such as Grindr, Tinder, Chispa and Bumble where the authors highlight some of the dangers associated with data mining and data sharing by the use of GSN apps. I also include the voices of participants, highlighting their experiences while using the given dating application. This essay highlights how systems of oppression such - racism, sexism, classism and misogyny have carried over into the digital age, where; POC and the LGBT community have been victims of discrimination based on sexual orientation, stereotypes and assumptions about ethnicity. During a three-week period, I conducted interviews and a focus group with college students, including POC and LGBT community members in California, about their experiences using dating apps such as, Tinder, Grindr, Bumble and Chispa. The insight from interviews, plus my observation and articulation with recent scholar work create the foundation for this study. Growing up in the age of technology where the use of dating apps has grown over the years I wanted to understand its purpose in the college sphere, I began to indulge in the use of dating apps and engaged in conversations with friends and peers about the use of a dating app in hopes of creating connections. These conversations sparked my interest in dating apps and the way they are used by adults and young adults, specifically in a college campus while thinking about the implications of data collected by dating app companies from its users

Design of the Data Description Language Processor

The Data Description Language (DDL) is a language for describing the structure of data, and expressing transformations that are to be performed on that data. The DDL Processor is a set of computer programs which interprets DDL statements and generates a computer program to perform the specified transformations. Together the DDL and its Processor provide a utility which can be used to perform jobs such as creating new data bases, reorganizing or extracting data from existing data bases, moving data to different storage devices, interfacing files between different programming languages, or between different operating systems. This report documents the design of the DDL Processor. Special features of the design include the use of special purpose internal languages, compiler-compiler techniques, bootstrapping methods, and a descriptor tree which aids in the parsing of input data

Research on Automatic Program Generation

Automatic Program Generation Research has been conducted under Contract N00014-67-A-0216-0014, since 1971. The objective of the research has been to provide software generation directly from user specifications. Initially, the research concentrated on a specific application, of generating file conversion programs. A first report on this subject was authored by Diane Pirog Smith, in December 1971, titled, An Approach to Data Description and Conversion . Subsequently, a software system for automating this function was implemented by Jesus A. Ramirez and described by him in a report titled, Automatic Generation of data conversion-programs Using A Data Description Language (DIL) . Currently, the objective of the research has been broadened to develop a user language and a software system for automatic generation of business oriented programs. This technical report contains a collection of three papers intended to summarize the results of past research and the direction of current research. The first paper, by Ramirez, Rin and Prywes is a summmary of Dr. Ramirez\u27s report and dissertation cited above. The second paper, titled, An Overview of a System for Automatic Generation of File Conversion Programs by. N. Adam Rin and Maxine Brown is intended to provide a more user oriented view based on their experience in utilization of the system developed by Ramirez. There have been many research activities and a large number of papers in this area. The third paper, Automatic Generation of Software Systems: A Survey, by N. Prywes serves to relate the research underway at the University of Pennsylvania, to the many recent and current activities in this field. It also aims to clearly define short and long term objectives and methodologies

The development of a measure of enculturation for Native American youth

Enculturation is the process by which individuals learn about and identify with their ethnic minority culture. It is distinguished from acculturation which refers to the process by which an ethnic minority individual is assimilated into the majority culture. Three studies with Native American youths are reported that describe the development of a measure of enculturation for Native American youths. Development of a measure of enculturation provides a foundation upon which to build a body of literature that focuses on strengths in a youth's life rather than on deficits. Results of the first study (n=120), a confirmatory factor analysis, indicated that cultural affinity, Native American identity, and family involvement in traditional activities adequately represent the construct of enculturation. The study also provides some convergent validity for this interpretation. The second study examines factor invariance for enculturation among youths with data from over 2 years (n=69). The factor structure was similar across time. The third study replicates the factor structure and validity analyses with a new sample (n=42). Usefulness of the measure for assessing protective factors and stressing ethnicity over simple assessment of race categories is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/117215/1/ajcpbf02510403.pd

Factores socioculturales que influyen en las usuarias de 50 años para la toma de papanicolau de un hospital nasca: Socio-cultural factors that influence 50-year-old users for papanicolau taking from a nasca hospital

Objective: The objective of this study was to determine the sociocultural factors in 50-year-old users for Pap smears at the Ricardo Cruzado Rivarola de Nasca hospital during the period December 2021 - February 2022.  Material and Methods: Observational, analytical, and prospective study. The study population is made up of 80 50-year-old users who attend the Ricardo Cruzado Rivarola hospital for Pap tests at the gynecology-obstetrics office and the sample is 67 users, selected by non-probabilistic sampling for convenience.  Results: For the first analysis, in simple and multiple regression, it was found that women with a high level of knowledge had a 384% and 382% higher frequency of having ever undergone a PAP, compared to those with a low level of knowledge.  Conclusions: The level of knowledge about the PAP has a relevant influence on having carried out a PAP; but also the women who had a high level were the ones who had the highest frequency of having done it. This added to the number of children; possibly because in the circles of women with children one of the topics to be discussed is about maternal health and within them the PAP.Objetivo: El objetivo del presente estudio fue determinar los factores socioculturales en usuarias de 50 años para la toma de Papanicolaou en el hospital Ricardo Cruzado Rivarola de Nasca durante el periodo diciembre 2021 – febrero 2022.  Materiales y Métodos: Realizamos un estudio observacional, analítica, y prospectivo. La población de estudio está constituida por 80 usuarias de 50 años que acuden al hospital Ricardo Cruzado Rivarola para controles de Papanicolaou al consultorio de ginecología-obstetricia. La muestra estuvo conformada por 67 usuarias, seleccionadas por muestreo no probabilístico por conveniencia.  Resultados: Para el primer análisis, en la regresión simple y múltiple, se encontró que las mujeres con nivel de conocimientos altos tenían 384% y 382% mayor frecuencia de haberse realizado alguna vez un PAP, en comparación a quienes tenían un nivel de conocimientos bajo. Conclusiones: El nivel de conocimiento sobre el PAP influye de una manera relevante al haberse realizado un PAP; pero además las mujeres que tuvieron mayor educación fueron las que tuvieron mayor frecuencia de haberlo realizado. Esto sumado a la cantidad de hijos; posiblemente porque en los círculos de mujeres con hijos uno de los temas a tratar es sobre la salud materna y dentro ellos el PA
