The Right to Die Debate: The Demonization of Dr. Kevorkian and the Creation of a Moral Panic Surrounding Physician-Assisted Suicide in the United States

The Right to Die Debate is a recent but highly controversial moral matter. In particular, physician-assisted suicide (PAS) is an issue that has been evaded by the medical community for years. As of 1990, most states had never encountered the issue before and therefore did not have any laws in place to prohibit PAS (Strate et. al, 2005). Dr. Jack Kevorkian, a retired pathologist from Royal Oak Michigan was the first to publicly address PAS. He brought the issue into the limelight through a bizarre and crude series of assisted deaths that had a lasting impact on not only the Right to Die Debate as whole, but on public policy and both federal and state governmental agendas. This study focuses on the way in which the media, in particular the New York Times (NYT) has portrayed Dr. Jack Kevorkian as incompetent, morally culpable and in an overall negative light in the past twenty years. Applying Stanley Cohen’s 1972 theory of moral panic, a content analysis of NYT media publications between 1990 and 1999 supports Cohen’s theory and reveals that the media has created a moral panic surrounding Kevorkian. This has in turn led to public policy that prevents both terminally ill individuals and their doctors from having a desirable choice; that of voluntary euthanasia and PAS.

Jack's Bay (the architecturalisation of memory)

Jack's Bay (the architecturalisation of memory) is a key work of the author's exhibition Lightsite, which toured Western Australian galleries from February 2006 to November 2007. It is a five-minute-long exposure photographic image captured inside a purpose-built, room-sized pinhole camera which is demountable and does not have a floor. The work depicts octogenarian Jack Morris, who for forty years held the professional salmon fishing license in the hamlet of Bremer Bay, on the SE coast of Western Australia. The pinhole camera-room is sited within sand dunes new Jack's now demolished beachside camp. Three generations of Jack's descendents stand outside the room - from his daughter to his great grand children. The light from this exterior landscape is 'projected' inside the camera-room and illuminates the interior scene which includes that part of the sand dune upon which the floorless room is erected, along with Jack who is sitting inside. The image evokes the temporality of light. Here, light itself is portrayed as the primary medium through which we both perceive and describe landscape. In this way it is through the agency of light that we construct our connectivity to landscape.

Jack's Bay

Jack's Bay expands understandings of the role of photographic media in the representation of landscapes. It does so by combining architectural construction with B&W photographic processing techniques. A purpose-built room-sized camera obscura is first constructed over a portion of the landscape to be recorded. Photosensitive paper is applied to the interior wall surfaces and is exposed to the inverted light entering a small aperture. These photographs are subsequently developed within the camera itself and consequently 'suffer' embellishments and aberrations from the makeshift darkroom conditions. In this way the specificity of both the landscape and the event of its recording are registered in the final image. Many images were destroyed in the process. The idea of the work is to help the viewer reflect on the role media plays in our understanding of landscape and to thus question the means by which they themselves record and interpret landscape representations.

Interfacing Jack and anybody : towards anthropometric musculoskeletal digital human modeling

Virtual prototyping emerges as a new technology to replace existing physical prototypes for product evaluation, which are costly and time consuming to manufacture. Virtualization technology allows engineers and ergonomists to perform virtual builds and different ergonomic analyses on a product. Digital Human Modelling (DHM) software packages such as Siemens Jack, often integrate with CAD systems to provide a virtual environment which allows investigation of operator and product compatibility. Although the integration between DHM and CAD systems allows for the ergonomic analysis of anthropometric design, human musculoskeletal, multi-body modelling software packages such as the AnyBody Modelling System (AMS) are required to support physiologic design. They provide muscular force analysis, estimate human musculoskeletal strain and help address human comfort assessment. However, the independent characteristics of the modelling systems Jack and AMS constrain engineers and ergonomists in conducting a complete ergonomic analysis. AMS is a stand alone programming system without a capability to integrate into CAD environments. Jack is providing CAD integrated human-in-the-loop capability, but without considering musculoskeletal activity. Consequently, engineers and ergonomists need to perform many redundant tasks during product and process design. Besides, the existing biomechanical model in AMS uses a simplified estimation of body proportions, based on a segment mass ratio derived scaling approach. This is insufficient to represent user populations anthropometrically correct in AMS. In addition, sub-models are derived from different sources of morphologic data and are therefore anthropometrically inconsistent. Therefore, an interface between the biomechanical AMS and the virtual human model Jack was developed to integrate a musculoskeletal simulation with Jack posture modeling. This interface provides direct data exchange between the two man-models, based on a consistent data structure and common body model. The study assesses kinematic and biomechanical model characteristics of Jack and AMS, and defines an appropriate biomechanical model. The information content for interfacing the two systems is defined and a protocol is identified. The interface program is developed and implemented through Tcl and Jack-script(Python), and interacts with the AMS console application to operate AMS procedures.

City meeting places: Brisbane's Hungry Jack's and Melbourne's Flinders Street Station

When arranging a place to meet in Brisbane, it has become almost second nature to say, “I’ll meet you outside Hungry Jack’s,” which is located in Queen Street Mall. In Melbourne, the common saying is, “I’ll meet you under the clocks,” which refers to the row of clocks above the main entrance to Flinders Street Railway Station. The saying “I’ll meet you under the clocks” is loaded with memory and history for most Melbournians—from WWII farewells to after school meetings. The clocks, and the station, have become part of the symbolic culture of the city. A feature of these two sites is the diversity of people who arrange to meet there, ranging from business people, tourists, teenagers, lovers, families to local schoolchildren. These two spaces cross boundaries of exclusion and enable people to feel as though they belong the city. While it seems appropriate for people to arrange to meet at a railway station, it is interesting that many people who meet at Flinders Street Station do not travel by train to arrive there: some walk; some take the tram and then walk; others arrive by bus. Similarly, most of the many people who arrange to meet outside Hungry Jack’s in Brisbane do not intend to enter the store...

Ergonomic assessment of hospital bed moving using DHM Siemens JACK

While the indirect and direct cost of occupational musculoskeletal disorders (MSD) causes a significant burden on the health system, lower back pain (LBP) is associated with a significant portion of MSD. In Australia, the highest prevalence of MSD exists for health care workers, such as nurses. The digital human model (DHM) Siemens JACK was used to investigate if hospital bed pushing, a simple task and hazard that is commonly associated with LBP, can be simulated and ergonomically assessed in a virtual environment. It was found that while JACK has implemented a range of common physical work assessment methods, the simulation of dynamic bed pushing remains a challenge due to the complex interface between the floor and wheels, which can only be insufficiently modelle

Reproductive biology of mangrove jack (Lutjanus argentimaculatus) in northeastern Queensland, Australia

Lutjanus argentimaculatus is an Indo-Pacific species that inhabits riverine, coastal and offshore reef habitats. An investigation of the reproductive biology of Lutjanus argentimaculatus in northeastern Queensland waters (Australia) was undertaken between 1999 and 2002. Individuals in inshore estuarine and freshwater riverine habitats were mostly immature whereas those captured in offshore reef waters were predominantly mature. Males matured at a smaller size than females, with the length-at-50%-maturity (Lm50) for males estimated to be 470.7 mm fork length (FL) and 531.4 mm FL for females. The spawning season in northeastern Queensland was mostly during the austral spring-summer and peaked in December. The presence of ripe female fish and occurrence of postovulatory follicles in histological sections provided evidence that spawning activity was more pronounced during the full and third quarter moon phases. Lutjanus argentimaculatus were highly fecund with estimates of up to 4 x 106 ova per spawning event. Immature fish concentrated in inshore areas where they were targeted by recreational fishers whereas, in offshore areas, commercial fishers caught predominantly larger, mature fish.

Biology, Management and Genetic Stock Structure of Mangrove Jack, (Lutjanus argentimaculatus) in Australia.

This project has contributed to the ecologically sustainable management of mangrove jack in Australia by providing comprehensive information on its biology, habitat requirements, population parameters and stock structure. Specifically, the project has resulted in an enhanced understanding of the life history of Australian mangrove jack, the levels of exploitation in its local fishery and the likely existence of a single genetic stock throughout Queensland.

Primary structure of a Thomsen-Friedenreich-antigen-specific lectin, jacalin [Artocarpus integrifolia (jack fruit) agglutinin]. Evidence for the presence of an internal repeat

Jacalin [Artocarpus integrifolia (jack fruit) agglutinin] is made up of two types of chains, heavy and light, with M(r) values of 16,200 +/- 1200 and 2090 +/- 300 respectively (on the basis of gel-permeation chromatography under denaturing conditions). Its complete amino acid sequence was determined by manual degradation using a 4-dimethylaminoazobenzene 4'-isothiocyanate double-coupling method. Peptide fragments for sequence analysis were obtained by chemical cleavages of the heavy chain with CNBr, hydroxylamine hydrochloride and iodosobenzoic acid and enzymic cleavage with Staphylococcus aureus proteinase. The peptides were purified by a combination gel-permeation and reverse-phase chromatography. The light chains, being only 20 residues long, could be sequenced without fragmentation. Amino acid analyses and carboxypeptidase-Y-digestion C-terminal analyses of the subunits provided supportive evidence for their sequence. Computer-assisted alignment of the jacalin heavy-chain sequence failed to show sequence similarity to that of any lectin for which the complete sequence is known. Analyses of the sequence showed the presence of an internal repeat spanning residues 7-64 and 76-130. The internal repeat was found to be statistically significant.

Composición química de la biomasa verde del pasto Guinea (Panicum maximum, Jack), CV Colonial, con diferentes niveles de inclusión de urea. Finca Santa Rosa, sabana Grande, Managua

Se llevó a cabo un estudio con el objetivo de determinar el mejoramiento de la composición química de la biomasa verde y tratada con Urea como proceso de amonificación. El pasto utilizado fue el Guinea (Panicum maximum, Jacq) CV Colonial el cual se encontraba en etapa de plena maduración (75 días). Durante el mes de septiembre del 2011 se realizó un corte de uniformidad para proceder al muestreo durante el mes de noviembre en la Finca Santa Rosa, Universidad Nacional Agraria. Managua, Nicaragua.Los tratamiento consistieron en cuatro niveles de plicación de Urea; 0, 1, 3 y 5 % en base al forraje verde a tratar, diluido en 0.5 lt de agua, y almacenados en bolsas de polietileno durante 21 días a temperatura ambiente.El diseño utilizado fue un DCA (Diseño completo al Azar) con tres repeticiones. Las variables de estudio para cada tratamiento fueron,porcentajes de; materia seca, proteína cruda, fibra ácido detergente (FAD), fibra neutro detergente (FND) y cenizas. Se realizaron análisis de varianza (ANDEVA) y separaciones de medias, usando Tukey (P<0.05). Para el análisis estadístico las variables codificadas en porcentajes se transformaron, según, 2 arco seno p (Dos veces Arco seno de la raíz cuadrada de la proporción).Se encontró diferencias significativas (P≤ 0.05) para las variables Materia seca (MS), Proteína Cruda (PC)y, Cenizas (CEN), no encontrando diferencias estadísticas ( P > 0.05) para las variables Fibra Neutro Detergente (FND) y Fibra Ácido Detergente FAD).El porcentaje de materia seca vario desde 48.04 % hasta 24.30 % para 0 y 5 % de Urea respectivamente. La PC pasó de 3.36 % para el tratamiento sin Urea a 8.37 % cuando se aplicó 5 % de Urea mientras la CEN aumento de 7.85 % a 8.60 % para 0 y 3 % de urea. La FDN y FAD aunque no presentaron diferencias estadísticas para los tratamientos evaluados, fue mejorado (disminución del contenido fibroso) con el tratamiento 5% de Urea. Se concluye que el tratamiento de 5 % de Urea es el más recomendado para la amonificación de forraje verde del pasto guinea (Panicum maximum, Jacq) CV Colonial. Con estos resultados se confirma que con el uso de esta tecnología se evidencia la transformación de materiales maduros de baja o nula calidad en alimentos que provean nutrientes al animal durante las épocas críticas
