Support for Freshmen at a Mass-University Program - The Cascaded Blended Mentoring Project

This paper describes a new mentoring project that is being carried out at the Faculty of Psychology at the University of Vienna. The general objective of this project is to help freshmen to manage the demands that come with mass-studies like Psychology. Senior students act as mentors for a group of freshmen by sharing the experiences and knowledge they already gained in their studies. The project is currently in its pilot phase and will start for the main test phase in fall 2007

Behavior of self-propelled acetone droplets in a Leidenfrost state on liquid substrates

It is demonstrated that non-coalescent droplets of acetone can be formed on liquid substrates. The fluid flows around and in an acetone droplet hovering on water are recorded to shed light on the mechanisms which might lead to non-coalescence. For sufficiently low impact velocities, droplets undergo a damped oscillation on the surface of the liquid substrate but at higher velocities clean bounce-off occurs. Comparisons of experimentally observed static configurations of floating droplets to predictions from a theoretical model for a small non-wetting rigid sphere resting on a liquid substrate are made and a tentative strategy for determining the thickness of the vapor layer under a small droplet on a liquid is proposed. This strategy is based on the notion of effective surface tension. The droplets show self-propulsion in straight line trajectories in a manner which can be ascribed to a Marangoni effect. Surprisingly, self-propelled droplets can become immersed beneath the undisturbed water surface. This phenomenon is reasoned to be drag-inducing and might provide a basis for refining observations in previous work

Maine Monthly Overdose Report for November 2021

During November there were a total of 773 fatal and nonfatal overdoses, including 64 (8%) confirmed and suspected fatal overdoses and 709 (92%) nonfatal overdoses. The proportion of fatal to nonfatal overdoses decreased from 9% to 7% between January and November. Deduplicated data derived from multiple statewide sources were compiled to reach these totals. These sources include nonfatal overdose incidents reported by hospital emergency rooms (ED), emergency medical service (EMS) responses without transport to the ED; overdose reversals reported by law enforcement; and overdose reversals reported by community members or agencies receiving state-distributed naloxone. There are an unknown number of private overdose reversals that were not reported and an unknown number of the community-reported reversals that may have overlapped with emergency response by EMS or law enforcement

Maine Monthly Overdose Report for July 2022

This report documents suspected and confirmed fatal and nonfatal drug overdoses in Maine during July 2022 as well as for the period January-July 2022. During July, the proportion of fatal overdoses averaged 7.9% of total overdoses. Monthly proportions of 2022 fatalities have fluctuated from a low of 5.3% in May 2022 to a high of 8.0% in April. During the first seven months of 2022, the average number of overdoses per month was approximately 836 (57 fatal and 779 nonfatal incidents )

Maine Monthly Overdose Report for December

During December 2021, there were 769 nonfatal and fatal overdoses in Maine, including 718 (93%) nonfatal and 51 (7%) confirmed or suspected fatal overdoses. The proportion of fatal to nonfatal overdoses decreased from 9% to 7% of total overdoses between January and December. Deduplicated data derived from multiple statewide sources were compiled to reach these totals: nonfatal overdose incidents reported by hospital emergency rooms (ED), emergency medical service (EMS) responses without transport to the ED, overdose reversals reported by law enforcement, and overdose reversals reported by community members or agencies receiving state-distributed naloxone. There are also an unknown number of private overdose reversals that were not reported, and an unknown number of the community-reported reversals that may have overlapped with emergency response by EMS or law enforcement

Maine Cumulative Monthly Overdose Report for January through May 2022

The proportion of fatal overdoses averaged 7% of total overdoses over the course of 2021 (Table 1) and has stayed at that level during the first five months of 2022 as a whole, although the monthly proportion of fatalities fluctuated from a low of 6% in January and May to 8% in April. During the first five months of 2021, the average number of overdoses per month was 658 (49 fatal and 609 nonfatal cases). During the first five months of 2022, the average number of overdoses per month was 792 (53 fatal and 739 nonfatal cases). The proportion of fatalities in January–May 2022 (266) is 9.0% higher than the first five months of 2021 (244)

Maine Monthly Overdose Report for August 2022

This report documents suspected and confirmed fatal and nonfatal drug overdoses in Maine during August 2022 as well as for the period January 2021–August 2022. During August, the proportion of fatal overdoses averaged 6.8% of total overdoses. Monthly proportions of 2022 fatalities have fluctuated from a low of 5.1% in May 2022 to a high of 8.0% in April. During the first eight months of 2022, the average number of overdoses per month was approximately 852 (58 fatal and 794 nonfatal incidents)

Maine Monthly Overdose Report for June 2022

This report documents suspected and confirmed fatal and nonfatal drug overdoses in Maine during June, 2022 as well as for January-June 2022

Maine Monthly Overdose Report for October 2021

During October there were a total of 870 fatal and nonfatal overdoses, including 60 (7%) confirmed and suspected fatal overdoses and 810 (93%) nonfatal overdoses. The proportion of fatal to nonfatal overdoses has decreased from 9% to 7% between January and October. Deduplicated data derived from multiple statewide sources were compiled to reach these totals. They include nonfatal overdose incidents reported by hospital emergency rooms (ED), emergency medical service (EMS) responses without transport to the ED; overdose reversals reported by law enforcement; and overdose reversals reported by community members or agencies receiving state-distributed naloxone. There are also an unknown number of private overdose reversals that were not reported and an unknown number of the community-reported reversals that may have overlapped with emergency response by EMS or law enforcement

Hash Tables for Embedded and Real-time systems

Common collection objects such as hash tables are included in modern runtime libraries because of their widespread use and efficient implementation. While operating systems and programming languages continue to improve their real-time features, common implementations of hash tables and other collection objects are not necessarily suitable for real-time or embedded-systems. In this paper, we present an algorithm for managing hash tables that is suitable for such systems. The algorithm has been implemented and deployed in place of Java’s Hashtable class. We present evidence of the algorithm’s performance, experimental results documenting our algorithm’s suitability for real-time, and lessons learned from migrating this data structure to real-time and embedded platforms
