Collaboration Versus Cheating

We outline how we detected programming plagiarism in an introductory online course for a master's of science in computer science program, how we achieved a statistically significant reduction in programming plagiarism by combining a clear explanation of university and class policy on academic honesty reinforced with a short but formal assessment, and how we evaluated plagiarism rates before SIGand after implementing our policy and assessment.Comment: 7 pages, 1 figure, 5 tables, SIGCSE 201

Engineering Students’ Perception of Academic Dishonesty at an American University in the Middle East

This study surveys engineering students’ perception of academic integrity at a private American university in the Middle East. The survey included questions on plagiarism, inappropriate collaboration, cheating on exams, copyright violations, and complicity in academic dishonesty. The study showed that more than one-third of the students were not aware that the university has a student academic integrity code. The gender appears to affect the students’ perception of academic dishonesty, as the female students perceived more frequent cheating than males. Also, about 10% of the female students, compared to about 30% of the male students, see no relationship between morality and academic integrity. The main reason why students cheat was because they had little time to do the work without seeking unauthorized help and because they perceive cheating as a form of collaborative work. Students believed that one of the most effective ways in reducing incidences of academic dishonesty is using more proctors during exams

Study of flow boiling characteristics of R134a in annulus of enhanced surface tubing

The paper presents an experimental study of the flow-boiling heat-transfer characteristics of R12 and R134a in the annulus of a horizontal enhanced-surface-tubing evaporator. The test section has an inner-tube bore diameter of 17.5 mm, an envelope diameter of 28.6 mm and an outer smooth tube of 32.3 mm inside diameter. The ranges of heat flux and mass velocity covered in the tests were 5–25 kW/m2 and 180–290 kg/m2/s, respectively, at a pressure of 365 kPa. In order to establish the flow regime conditions at the inlet to the test section, the test rig allows for the visualization of refrigerant flow through the preheater. The experiments show two regions of heat transfer: a nucleate boiling region where the heat transfer depends mainly on heat flux, and a forced convective region where the heat transfer depends only on the refrigerant flow rate

Faculty perception of engineering student cheating and effective measures to curb it

© 2019 IEEE. Engineering faculty were surveyed on issues related to academic dishonesty by students affiliated with their college at an American university located in the United Arab Emirates. The survey addressed perceived frequency of plagiarism, unauthorized collaboration, cheating, copyright violations and complicity in academic integrity. As expected, the majority of the faculty think that dishonesty is more common in-of-class work compared to proctored exams. They think that applying tougher penalties and using more proctors are the most effective methods in decreasing academic dishonesty. The authors believe that it would be helpful if faculty members follow the university\u27s policy on cheating rather than make up their own rules in order to have consistent approach in dealing with academic dishonesty violations across the whole university. Ideally, the best way to combat dishonest acts at an institution is by educating students through seminars and workshops about the virtues of academic integrity and the benefits it brings to society. But until our campuses become free of dishonest behavior by students, some practical measures should be undertaken by the faculty to safeguard the institution against unethical behavior by students. For example, faculty members are recommended to either make their own assignments or modify the end-of-chapter problems from textbooks because students may have access to solution manuals. They are encouraged to give different homework problems and projects from one semester to another since students may have access to graded past work. While test banks provided to faculty by publishers may be used as a guide when creating exams, problems from such sources should not be put verbatim on exams by faculty because they are often available for purchase by students on the internet. Furthermore, the weight of-of-class assignments relative to the total course grade should be a small fraction of the total weight to discourage students from cheating on homework. Wireless signal jamming devices can combat some acts of e-cheating that utilizes the internet by disrupting communication between a smart phone and the cell-phone base station

DNA damage induced during mitosis undergoes DNA repair synthesis.

Understanding the mitotic DNA damage response (DDR) is critical to our comprehension of cancer, premature aging and developmental disorders which are marked by DNA repair deficiencies. In this study we use a micro-focused laser to induce DNA damage in selected mitotic chromosomes to study the subsequent repair response. Our findings demonstrate that (1) mitotic cells are capable of DNA repair as evidenced by DNA synthesis at damage sites, (2) Repair is attenuated when DNA-PKcs and ATM are simultaneously compromised, (3) Laser damage may permit the observation of previously undetected DDR proteins when damage is elicited by other methods in mitosis, and (4) Twenty five percent of mitotic DNA-damaged cells undergo a subsequent mitosis. Together these findings suggest that mitotic DDR is more complex than previously thought and may involve factors from multiple repair pathways that are better understood in interphase

Desain Dan Implementasi Sistem Penyusunan Jadwal Asisten Praktikum Pada Laboratorium Komputer Sekolah Tinggi Manajemen Informatika Dan Komputer (STMIK) Pradnya Paramita Malang Menggunakan Algoritma Genetika

Scheduling at the College of Information Management and Computer Pradnya Paramita Malang (STIMATA) is a routine that is always done at every turn of the semester. One of the scheduling assistant in the laboratory. Currently scheduling lab assistant in STIMATA is still done manually. Students who wish to register as a lab assistant, must submit a schedule of lectures and lab courses specialization are available. Coordinator / Lab administration then choose which of the candidates for an assistant who register to be placed in the laboratory according to the specialty. However, if the schedule constraints often occur in conjunction with the lab assistant lecture schedule as a student STIMATA. Therefore we need a system that can automatically schedule the deployment assistant fast and easy and can solve problems in the manufacturing schedule. Genetic algorithm is a method often used in the search for the best solution of the many solutions, especially in the case of scheduling. Therefore, it is expected through the facility / application might help solve the problems at the lab assistant schedule preparation STIMATA as a case study in to provide the optimum solution using a genetic algorithm

A symmetry for vanishing cosmological constant

Two different realizations of a symmetry principle that impose a zero cosmological constant in an extra-dimensional set-up are studied. The symmetry is identified by multiplication of the metric by minus one. In the first realization of the symmetry this is provided by a symmetry transformation that multiplies the coordinates by the imaginary number i. In the second realization this is accomplished by a symmetry transformation that multiplies the metric tensor by minus one. In both realizations of the symmetry the requirement of the invariance of the gravitational action under the symmetry selects out the dimensions given by D = 2(2n+1), n=0,1,2,... and forbids a bulk cosmological constant. Another attractive aspect of the symmetry is that it seems to be more promising for quantization when compared to the usual scale symmetry. The second realization of the symmetry is more attractive in that it is posible to make a possible brane cosmological constant zero in a simple way by using the same symmetry, and the symmetry may be identified by reflection symmetry in extra dimensions.Comment: Talk in the conference IRGAC 2006, 2nd International Conference on Quantum Theories and Renormalization Group in Gravity and Cosmology, Barcelon
