The attitudes and experiences of families with death determination in the home

The purpose of this study is to describe the attitudes and experiences of family members with respect to death determination practices for the terminally iii clients of home care agencies. A sample of family 53 members in Southeast Michigan returned survey questionnaires. The findings indicate that police and emergency medical technicians most frequently respond to the call when a person with a terminal illness has died. Fifty percent of the family members reported feeling sad, 35 percent reported feeling relieved and 18 percent of the respondents felt angry about the arrival of multiple personnel. Feelings of anger were signficantly associated with the absence of a nurse at the time of death, the use of lights and sirens, disrespectful personnel and the arrival of multiple personnel. Feelings of anger were also significantly associated with continuing thoughts of the day of death by family members. Results suggest the need to rethink state and local laws in regard to death determination and to educate those most likely to respond to families sensitively. Home care agencies and hospices should also encourage attendance by nurses at the time of death.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67059/2/10.1177_104990918900600504.pd

In vitro bond strength of treated direct-bonding metal bases

Three types of direct-bonding metal bases were used to determine the effect of five commercial surface treatments on in vitro tensile bond strength. The proprietary treatments were etching, silanation, surface activation, etching plus silanation, and etching plus surface activation. Nontreatment was used as a control. The bases were of the mesh, photo-etched, and grooved types. Bases were loaded with a no-mix adhesive to plastic substrates. The grooved base had the highest bond strength with no treatment. Etching improved the bond strength of the grooved bracket by 56%. Silanation improved the bond strength of the mesh bracket by 28%. Surface treatments did not improve the bond strength of the photo-etched bracket.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25602/1/0000149.pd

Ethical and Legal Standards for Research in Prisons

Biobehavioral research, especially that which is conducted with prisoners, has become much more closely regulated in the last 30 years. State and federal law, as well as professional standards, regulate the conduct of many types of research; in the case of prisoners, this regulation is even more stringent. However, currently no mandatory, uniform, national regulatory or oversight process exists, and many privately funded research endeavors are operating in a regulatory void. In response to this, the National Bioethics Advisory Commission has argued for the creation of a single, national, independent regulatory body to oversee all human participant research, regardless of funding source. As ethicolegal research standards evolve alongside advances in science and technology, an appreciation of the history of prisoner research and an awareness of current standards is critical to conducting ethical prison research

Burbot Early Life History Strategies in the Great Lakes

Burbot Lota lota exhibit four previously known reproductive strategies in the Great Lakes region. In this paper we review those strategies and provide evidence for a fifth one—delayed deepwater spawning. The four known, shallow‐water strategies are as follows: (1) spawning by self‐sustaining, landlocked populations, (2) spawning in tributaries in winter and the exit of larvae to a Great Lake, (3) spawning by residents in a spawning stream with access to a Great Lake, and (4) spawning on unconsolidated and rocky areas in shallow water in winter in the lake proper. Resident, landlocked populations exist in some Michigan and Wisconsin rivers (e.g., the Muskegon River in Michigan). The evidence for winter tributary spawning is the appearance of newly hatched Burbot in the St. Marys and Bark rivers during April–June. Evidence for Burbot juveniles leaving spawning streams is U.S. Fish and Wildlife Service tributory mouth trap data. The evidence for winter nearshore spawning comes from power plant monthly entrainment studies (Mansfield et al. 1983). Our proposed fifth strategy is spring and summer spawning at deep reefs, where there is probably cobble or boulder habitat. Our evidence comes from midlake reefs in Lake Michigan and offshore areas of Lake Huron: (1) we collected adult Burbot at midlake reefs in Lake Michigan, (2) we collected many Burbot larvae (many of which were newly hatched) from Lakes Michigan and Huron in June–August, and (3) we collected a Burbot egg in a PONAR grab in mid‐July from 73 m in southern Lake Huron. An important question remains, namely, which life history strategy provides the highest recruitment success for this species. It may be that adaptability ensures the survival of this important, top‐predator fish during periods of crisis (e.g., encounters with dams, Sea Lamprey Petromyzon marinus predation).Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/141895/1/tafs1733.pd
