Those who are detained or have their supervision revokedbefore trial are more likely to go to prison, and for longerperiods

Those who encounter the court system are guaranteed equal treatment under the Constitution, but is this always the case? Does being detained before trial affect a person’s likelihood of going to prison? In new research that examines the cases of more than 90,000 federal defendants, James C. Oleson and his colleagues find that those released before trial were far less likely to be sent to prison if convicted, and if they were, for far shorter periods than those who were not released or who had their pretrial supervision revoked. He argues that this sort of sentencing disparity should be of interest to federal prosecutors and judges alike

Rituals Upon Celluloid: The Need For Crime and Punishment in Contemporary Film

Most members of the public lack first-hand experience with the criminal justice system; nevertheless, they believe that they possess phenomenological knowledge about it. In large part, the public’s understandings of crime and punishment are derived from television and film, which provide modern audiences with a vision of institutions that are normally occluded from view. While public rituals of punishment used to take place on the scaffold, equivalent moral narratives about crime and punishment now occur on film because modern punishment is imposed outside of the public gaze. Yet because crime films distort what they depict, the public’s view of crime and punishment may not correspond to social realities. Thus, instead of building social solidarity as Adam Smith, Émile Durkheim, and Kai Erikson suggest, mass media may actually increase the public’s fear of crime, increase rates of offending, and fuel a cycle of punishment-as-entertainment and penal populis

A High Power Solar Electric Propulsion - Chemical Mission for Human Exploration of Mars

Recently Solar Electric Propulsion (SEP) as a main propulsion system has been investigated as an option to support manned space missions to near-Earth destinations for the NASA Gateway spacecraft. High efficiency SEP systems are able to reduce the amount of propellant long duration chemical missions require, ultimately reducing the required mass delivered to Low Earth Orbit (LEO) by a launch vehicle. However, for long duration interplanetary Mars missions, using SEP as the sole propulsion source alone may not be feasible due to the long trip times to reach and insert into the destination orbit. By combining an SEP propulsion system with a chemical propulsion system the mission is able to utilize the high-efficiency SEP for sustained vehicle acceleration and deceleration in heliocentric space and the chemical system for orbit insertion maneuvers and trans-earth injection, eliminating the need for long duration spirals. By capturing chemically instead of with low-thrust SEP, Mars stay time increases by nearly 200 days. Additionally, the size the of chemical propulsion system can be significantly reduced from that of a standard Mars mission because the SEP system greatly decreases the Mars arrival and departure hyperbolic excess velocities (V(sub infinity))

Medical Students’ Experiences of Part-Time Hospital Work: A Qualitative Study

This qualitative study explored the experiences of medical science students of part-time hospital work. Twenty-four participants from Guilan University of Medical Sciences in Rasht, Iran were recruited purposively from the fields of nursing (10 students), surgery (4 students), laboratory sciences (4 students), radiology (3 students), and anesthesiology (3 students). Data were collected through semi-structured face-to-face interviews and were analyzed through conventional content analysis. Data analysis identified three main themes and eight sub-themes: perceived personal benefits (effective learning, improved self-confidence, financial gain), organizational outcomes (operational benefits, unprofessional care delivery), unpleasant clinical environment (job burnout, financial strains, academic discouragement). The data indicate that part-time hospital work, although fostering learning and providing income, also poses challenges such as burnout for the student. Healthcare authorities, managers, and policy makers can use these findings to improve the effectiveness of students’ part-time work in hospital

Coronary Care Unit Nurses’ Experiences of Care Management Self-Efficacy: A Qualitative Content Analysis

Recognizing various aspects of the self-efficacy concept in specialized medical units such as intensive care units (ICUs) and coronary care units (CCUs) has the potential to help nurses improve their quality of care. Therefore, we conducted a qualitative content analysis study in 2018 in hospitals of the Guilan Province, northern Iran, to help explain nurses’ perceptions of self-efficacy in care management within CCU wards. Thirty-four semi-structured interviews were conducted with nurses from CCUs. Using Graneheim and Lundman’s (2004) analytical techniques, we extracted three main themes and nine sub-themes from the data: decline in self-efficacy (e.g., time constraint, high work pressure, emotional stresses, and loss of motivation); care development (e.g., experience-based care, knowledge-based care, and personal capability); and organizational challenges (e.g., weak management and unavailable physician). Our findings suggest that decreases in nurse self-efficacy (and resulting weak care management) could be prevented by establishing clear plans and enrolling nurses into appropriate training courses. The constant development of knowledge and experience alongside supportive supervisors and physicians are also effective in improving nurses’ self-efficacy

Innovative interstellar explorer

An interstellar "precursor" mission has been under discussion in the scientific community for at least 30 years. Fundamental scientific questions about the interaction of the Sun with the interstellar medium can only be answered with in situ measurements that such a mission can provide. The Innovative Interstellar Explorer (IIE) and its use of Radioisotope Electric Propulsion (REP) is being studied under a NASA "Vision Mission" grant. Speed is provided by a combination of a high-energy launch, using current launch vehicle technology, a Jupiter gravity assist, and long-term, low-thrust, continuous acceleration provided by an ion thruster running off electricity provided by advanced radioisotope electric generators. A payload of ten instruments with an aggregate mass of ~35 kg and requiring ~30 W has been carefully chosen to address the compelling science questions. The nominal 20-day launch window opens on 22 October 2014 followed by a Jupiter gravity assist on 5 February 2016. The REP system accelerates the spacecraft to a "burnout" speed of 7.8 AU per year at 104 AU on 13 October 2032 (Voyager 1's current speed is ~3.6 AU/yr). The spacecraft will return at least 500 bits per second from at least 200 AU ~30 years after launch. Additional (backup) launch opportunities occur every 13 months to early 2018. In addition to addressing basic heliospheric science, the mission will ensure continued information on the far-heliospheric galactic cosmic ray population after the Voyagers have fallen silent and as the era of human Mars exploration begins
