This paper presents the evaluation of a program designed to improve transfer outcomes for community college students pursuing an engineering degree. The program, the Engineering Admissions Partnership Program (E-APP), was designed to improve the navigational success of community college transfer students through connections to the university. These connections include coordinated academic advising, peer-mentoring, campus visits, and online social and professional networks. The objective of the study is to determine the efficacy of the E-APP and its interventions, which will be measured by increased participation rates and increased university retention rates for E-APP participants. Outcome data for the students are analyzed …


Does Lecture Capture Make A Difference For Students In Traditional Classrooms, Amber Settle, Lucia Dettori, Mary Jo Davidson Jun 2011

Does Lecture Capture Make A Difference For Students In Traditional Classrooms, Amber Settle, Lucia Dettori, Mary Jo Davidson

Amber Settle

The College of Computing and Digital Media (CDM) at DePaul University has recorded thousands of courses using an in-house system called Course Online (COL) since 2001. These recordings are available not only to students enrolled in online CDM courses, but also to students in traditional classrooms at CDM. In this study we analyzed survey responses and grade data to determine whether traditional students found COL recordings to be a valuable substitutional tool and whether the recordings had any impact on student performance. We found that a large majority of traditional CDM students find the recordings useful and believe that they …


The European Court Of Human Rights Ruling Against The Policy Of Keeping Fingerprints And Dna Samples Of Criminal Suspects In Britain, Wales And Northern Ireland: The Case Of S. And Marper V United Kingdom, Katina Michael Dec 2010

The European Court Of Human Rights Ruling Against The Policy Of Keeping Fingerprints And Dna Samples Of Criminal Suspects In Britain, Wales And Northern Ireland: The Case Of S. And Marper V United Kingdom, Katina Michael

Associate Professor Katina Michael

In England, Wales and Northern Ireland, the Police and Criminal Evidence Act 1984 (the PACE) contained powers for the taking of fingerprints, and samples in the form of deoxyribonucleic acid (DNA). In 2001, Section 64(1A) of the PACE was substituted with Section 82 of the Criminal Justice and Police Act. The change to legislation meant that a suspect of a crime would have their fingerprints and samples permanently stored on the police national computer (PNC) even after having been acquitted. This paper critically analyses the circumstances of the landmark case of S. AND MARPER V. THE UNITED KINGDOM in two …


The Legal, Social And Ethical Controversy Of The Collection And Storage Of Fingerprint Profiles And Dna Samples In Forensic Science, K. Michael Jun 2010

The Legal, Social And Ethical Controversy Of The Collection And Storage Of Fingerprint Profiles And Dna Samples In Forensic Science, K. Michael

Associate Professor Katina Michael

The collection and storage of fingerprint profiles and DNA samples in the field of forensic science for non-violent crimes is highly controversial. While biometric techniques such as fingerprinting have been used in law enforcement since the early 1900s, DNA presents a more invasive and contentious technique as most sampling is of an intimate nature (e.g. buccal swab). A fingerprint is a pattern residing on the surface of the skin while a DNA sample needs to be extracted in the vast majority of cases (e.g. at times extraction even implying the breaking of the skin). This paper aims to balance the …


Acetate Retention And Metabolism In Thehyporheic Zone Of A Mountain Stream, Michelle A. Baker Jan 1999

Acetate Retention And Metabolism In Thehyporheic Zone Of A Mountain Stream, Michelle A. Baker

Michelle A. Baker

An in situ acetate injection was used to determine the influence of labile dissolved organic carbon (DOC) availability on microbial respiration in the hyporheic zone of a headwater stream. We added bromide as a conservative tracer and acetate as an organic substrate to the hyporheic zone of Rio Calaveras, New Mexico, via an injection well. Tracer was observed in four of eight capture wells. Three of the four wells showed increases in bromide without concurrent increases in acetate concentration, suggesting 100% acetate retention. One well had 38% acetate retention. Pore velocity and acetate retention were negatively correlated, suggesting hydrologic control …
