Open Borders

This chapter seeks to problematize the so-called open borders option as a means for undermining the oppressive constraints associated with socially undocumented identity. Its goal is to create conceptual space for a philosophical conversation about the legitimacy of our current system of borders and its relationship to ongoing socially undocumented oppression that is not beholden to established frameworks of the established open borders debate. First, it explores a range of reasons why one might argue that opening borders could reduce socially undocumented oppression. Second, it argues that despite this appeal of an open borders policy, such oppression could nevertheless continue to exist in an “open borders world.” Third, it argues positively that eliminating borders is not, at present, the most effective means for addressing socially undocumented oppression.

Recycle Rate

In this study, the effects of recycle on anaerobic baffled reactor performances in treating palm oil mill effluents were investigated and biokinetic parameters were also determined. Recycle-ratio effect studies were carried out at the average loading rate of 15.6 g COD/l/d with the recycle rate varied from 5 to 25 times of the fresh-feed rate. The study shows that in the current system, a recycle of more than 15 times is needed to maintain the system pH higher than 6.8 without alkalinity supplementation, and the imposition of recycle is an effective means to reduce alkalinity requirements. Moreover, the kinetic model for substrate utilization and methane production proposed by Bathakur et al. (1991) was able to show the domination of certain culture in anaerobic processes. The model was also found to predict the experimental data of the present study with good accuracy.

The Future

In the future air traffic management (ATM) system, flight crews will most likely have the option to dynamically adjust their flight path without prior approval from the ground. As a result, knowledge of intent may no longer be shared by pilots and controllers, and the potential for unforeseen conflicts as well as the need for immediate yet coordinated interventions can be expected to increase. To support such a short-term reactive approach to traffic management and separation, highly effective means of communication will be required that allow for a rapid creation and update of shared frames of reference. It is not clear that recently developed and envisioned communication media and technologies are designed with these goals in mind. A recent line of research explored the ability of two communication systems - DataLink and the Voice Control and Switching System (VSCS)—to handle communication not only in the current air traffic control system but to also support the highly flexible operations and new coordination and knowledge demands that are likely going to be part of the future ATM system. System reviews, conceptual simulations, and a pilot survey served to gather information on current and potential future experiences with these systems. The results of our research suggest that neither system is tailored to future ATM operations, and that they create new challenges even in the context of the current system.

Chronic pyelonephritis is one of the most common diseases of the kidney and accounts for a sizeable number of cases of renal insufficiency in man, however its pathogenesis requires further elucidation. Transmission electron microscopy may serve as a uniquely effective means of observing details of the nature of this disease. The present paper describes preliminary results of an ultrastructural study of chronic pyelonephritis in Macaca arctoides (stumptail monkey).The infection was induced in these experiments in a retrograde fashion by means of a unilateral catheterization of the left ureter whereby an innoculum of 10 cc of broth containing approximately 2 billion E. coli per cc and radio-opaque dye were injected under pressure (mimicing vesico-ureteric reflux).

Abstract Mentoring has long been believed to be an effective means of developing students' clinical, research, and teaching skills to become competent professionals. The American Speech-Language-Hearing Association (ASHA) has developed two online mentoring programs, Student to Empowered Professional (S.T.E.P. 1:1) and Mentoring Academic Research Careers (MARC), to aid in the development of students. This paper provides a review of the literature on mentoring and compares and contrasts mentoring/mentors with clinical supervision/preceptors. Characteristics of effective mentors and mentees are offered. Additionally, the benefits of clinical mentoring such as, teambuilding in the workplace, retention of new staff, leadership development, and improved job satisfaction are discussed.

To Receive

Background: In China, where follow-up with hospitalized attempters is generally lacking, there is a great need for inexpensive and effective means of maintaining contact and decreasing recidivism. Aims: Our objective was to test whether mobile telephone message contacts after discharge would be feasible and acceptable to suicide attempters in China. Methods: Fifteen participants were recruited from suicide attempters seen in the Emergency Department in Wuhan, China, to participate in a pilot study to receive mobile telephone messages after discharge. All participants have access to a mobile telephone, and there is no charge for the user to receive text messages. Results: Most participants (12) considered the text message contacts an acceptable and useful form of help and would like to continue to receive them for a longer period of time. Conclusions: This suggests that, as a low-cost and quick method of intervention in areas where more intensive follow-up is not practical or available, telephone messages contacts are accessible, feasible, and acceptable to suicide attempters. We hope that this will inspire future research on regular and long-term message interventions to prevent recidivism in suicide attempters.
