The Girl Talk Dilemma: Can Copyright Law Accomodate New Forms of Sample-Based Music?

On Gregg Gillis’ laptop computer are thousands of files representing a vast slice of 20th and 21st century popular music.1 His digital music collection is similar to that of many music consumers: it spans a wide variety of genres and runs from the obscure to the mainstream. But Gillis is different from most music consumers in that he uses computer software to cut his digital music files into audio snippets, or samples, and then piece them together into song collages.2 Gregg Gillis is Girl Talk, a recording artist on the Illegal Art label whose music has made yearend best music lists in Time Magazine,3 Rolling Stone,4 Blender5 and Pitchforkmedia.com.6 Girl Talk has developed a strong following throughout the United States and has toured throughout Europe and Australia.7 A PC user, he was recently featured in one of the “I’m a PC” ads for Microsoft.8 But while Girl Talk has been successful, Gillis adds almost no original musical content to his recordings. Although he often alters the speed or pitch of his samples, or loops them in a continuous pattern, he does not sing or rap over his creations. Furthermore, Gillis has never sought licenses or authorization for any of the samples he uses.9 For instance, his latest album, “Feed the Animals,” includes over 300 unauthorized samples10 of artists ranging from Lil Wayne to Radiohead to Metallica to Kenny Loggins

Spotlight on Assistance Dogs-Legislation, Welfare and Research

Assistance dogs are a very diverse group of working dogs that are trained to assist humans with different types of disabilities in their daily lives. Despite these dogs' value for humankind, research on their welfare status, cognitive and behavioural capacities, selection criteria for the best fitting individuals, effective training and management practices, and genetic issues are so far lacking. This review highlights the need to address these topics and to promote progress in legal issues around assistance dogs. The topic of assistance dogs is approached comprehensively by outlining the current status of knowledge in three different dimensions: (1) the legal dimension, outlining important legal issues in the EU and Australia; (2) the welfare dimension; and (3) the dimension of research, covering assistance dog selection and training. For each of these three dimensions, we discuss potential approaches that can be implemented in the future in order to support assistance dog working performance, to protect the dogs' welfare, and to improve our knowledge about them. Additionally, there remain many legal issues, such as the presence of assistance dogs in public areas, the resolution of which would benefit both the assistance dog and the owner with disability

Dogs are not better than humans at detecting coherent motion

The ability to perceive motion is one of the main properties of the visual system. Sensitivity in detecting coherent motion has been thoroughly investigated in humans, where thresholds for motion detection are well below 10% of coherence, i.e. of the proportion of dots coherently moving in the same direction, among a background of randomly moving dots. Equally low thresholds have been found in other species, including monkeys, cats and seals. Given the lack of data from the domestic dog, we tested 5 adult dogs on a conditioned discrimination task with random dot displays. In addition, five adult humans were tested in the same condition for comparative purposes. The mean threshold for motion detection in our dogs was 42% of coherence, while that of humans was as low as 5%. Therefore, dogs have a much higher threshold of coherent motion detection than humans, and possibly also than phylogenetically closer species that have been tested in similar experimental conditions. Various factors, including the relative role of global and local motion processing and experience with the experimental stimuli may have contributed to this result. Overall, this finding questions the general claim on dogs' high performance in detecting motion

Body image perception and body composition: assessment of perception inconsistency by a new index

BACKGROUND: A correct perception of the body image, as defined by comparison with actual anthropometric analyses, is crucial to ensure the best possible nutritional status of each individual. Bioimpedance analysis (BIA) represents a leading technique to assess body composition parameters and, in particular, the fat mass. This study examined the self-perception of body image at various levels of adiposity proposing a new index. METHODS: We investigated 487 young Italian adults (mean age of males: 21.9 ± 2.4 years; mean age of females: 21.0 ± 2.2 years). Each subject could choose, on the Contour Drawing Rating Scale, the silhouette that he/she considered most resembling his/her perceived body image as well as his/her ideal body image. On each subject, we performed anthropometric measurements and determined the values of Fat mass and  út with BIA. A new index, FAIFAT (Feel fat status minus Actual fat status Inconsistency), was developed to evaluate possible fat status perception inconsistencies by BIA. RESULTS: Based on ideal and feel body image comparison, women showed higher dissatisfaction than men and preferred slimmer silhouettes. FAIFAT values indicated that the fat status perception was correct in the majority of the examined individuals and only three subjects showed a serious misperception. CONCLUSIONS: Our findings suggest that FAIFAT is an appropriate index for assessing the perceived fat status from the body image when compared with data obtained by BIA. In a population, the use of this index will allow the correct identification of groups at risk for eating disorders

A Case of Henoch-Schonlein Purpura Associated with Rotavirus Infection in an Elderly Asian Male and Review of the Literature.

BACKGROUND Henoch-Schönlein purpura (HSP), a small vessel vasculitis mediated by deposition of immune-complexes containing IgA in the skin, gut, and glomeruli, often presents with abdominal pain, purpuric rash in the lower extremities and buttocks, joint pain, and hematuria. The disease most commonly targets children but can affect adults who tend to have a worse prognosis. CASE REPORT We discuss a case of HSP in an elderly Chinese male who presented with severe proximal bowel inflammation, vasculitic rash, and proteinuria; he was found to have positive stool rotavirus and giardia. He improved significantly with high dose steroids. We believe rotavirus may have been a triggering event in this patient. A brief review of the literature is also presented. CONCLUSIONS This is the first case report describing a classic presentation of HSP in an adult following a rotavirus infection. HSP can cause significant morbidity and mortality in adult patients predominantly from progressive renal failure; therefore careful management and monitoring is important. GI infections seem to be a common trigger for HSP and this case report suggests that rotavirus may be part of the spectrum

-Heroines’ Journey- Emerging Story by Refugee Women during Group Analytic Music Therapy

There has been some evidence of the benefits of participating in group analytic music therapy with traumatized people. This pilot clinical project investigates the impact of a combination of narrative therapy and group analytic music therapy on refugee/newcomer women in Canada. An ongoing therapy group met for a period of 8 sessions, to share stories and feelings of past experiences and of resettlement. The focus of this group was emotional expression (verbal and musical). Musical listening, improvisation, art, writing, clay-work, and relaxation techniques were used. Several consistent themes re-emerged, including feelings around loneliness, fear guilt, and loss. The analysis of the therapy process showed many commonalities among these women and the process they were going through to deal with their feelings

Flop to Flip: Integrating Technology and Team-based Learning to Improve Student Engagement

Purpose: The first attempt to develop and instruct a new course in evidence-based practice in a physical therapy curriculum proved problematic. The purpose of this paper is to describe the method of revising this traditionally taught course using a combination of flipping the classroom, team-based learning, and technology. Methods: Working with an Instructional Design Specialist, a weekly online preparatory module was created for each content topic using a variety of multimedia learning provisions including micro learning videos (PowerPoint with voiceover), transcript of the PowerPoint, a list of vocabulary words, reading, Quizlet, Flipgrids and Concept Checks. Each week’s module was introduced with a listing of objectives, goals, time to complete tasks and a description of the in-class activities. Class began with a weekly 10-question vocabulary quiz to hold students accountable for their preparation. A short summary lecture followed. Students were then given an in-class assignment to complete either in pairs or small groups. Discussion of the assignment completed the session. Most of the assignments were submitted electronically prior to discussion for grading purposes. Several also utilized a team-based learning format. Pairs of students complete an assignment; students then convene with their group and discuss and complete the same assignment. This process facilitates a more active learning environment. Result: Students were consistently prepared for class as evidenced by their quiz performance. Informal assessment of the online preparatory modules was performed using a “One-Minute Paper” assessment. Students reported that the PowerPoint with voiceover, Quizlet, Concept Checks, and the weekly list of vocabulary terms were most helpful, whereas Flipgrids and reading were not helpful. In-class activities were interactive and facilitated deeper conversations about the content. Conclusion and Recommendations: The outcomes provided reflect student perception solely, which may have been biased by the instructor’s presence in the course. Formal assessment of changes was not possible using student performance as a measure because the course had dramatically changed from year one to year two. A more formal, scientific assessment is recommended to determine if and how course changes affected student performance

PtSi Clustering In Silicon Probed by Transport Spectroscopy

Metal silicides formed by means of thermal annealing processes are employed as contact materials in microelectronics. Control of the structure of silicide/silicon interfaces becomes a critical issue when the device characteristic size is reduced below a few tens of nanometers. Here we report on silicide clustering occurring within the channel of PtSi/Si/PtSi Schottky barrier transistors. This phenomenon is investigated through atomistic simulations and low-temperature resonant tunneling spectroscopy. Our results provide evidence for the segregation of a PtSi cluster with a diameter of a few nanometers from the silicide contact. The cluster acts as metallic quantum dot giving rise to distinct signatures of quantum transport through its discrete energy states
