Smoking Restrictions, Bans Rise in Hospitality Industry

With the rise of smoking restrictions and bans in the hospitality industry the author discusses solutions that are implemented to protect the workforce and guests from involuntary smoking. Historical and societal contexts are drawn, and enforcement of smoking bans as well as their economic impact is explored in an international perspective, primarily since US researchers have propelled the research on smoking and health issues. The author illustrates that there has been no way to avoid enforcements of strict smoking restrictions, and the struggle to do so could just delay the process and waste resources.

Caring and being cared -for: Perceptions of adolescent males at -risk for school failure

This qualitative study used grounded theory methods and purposeful sampling to explore perceptions on caring and being cared-for. Twenty-four adolescent male participants, identified as at-risk for school failure, completed a two phase interview process exploring these phenomena within three relationships; the relationship with the friend, with the most caring person they knew and with the teacher they felt cared for them. ^ Each participant was asked a predetermined set of open questions in an initial semi-structured interview. In addition each participant was encouraged to explore his own reflections on caring. A second interview allowed for member checking and for the participant to continue sharing his meaning of caring and being cared-for. ^ Line by line analysis with open, axial and selective coding was applied to interview transcripts along with a constant comparative method. Results indicated that the core category integrating all other categories was attachment bonding. Participants' stories manifested characteristics of proximity seeking, secure base, safe haven and distress upon involuntary separation from an attachment figure. ^ Strategies facilitating attachment bonding were influenced by the power positions of the relational players. Participants responded positively to the one-caring when they felt cared-for. Results further indicated that participants did not need to feel a sense of belonging in order to feel cared-for. Teacher behaviors indicating openness for authentic connections with students were specific to teacher's friendliness and professional competence. Teachers who nurtured feelings of being cared-for were uncommon in the participants' educational experience. ^ The number of adolescent males leaving high school prematurely is both a personal problem and a social problem. Despite a “mask” of indifference often exhibited by adolescent males at-risk for school failure, teachers might consider the social/emotional needs of these students when implementing the curriculum. In addition, policy makers might consider the social/emotional needs of this vulnerable population when developing programs meant to foster psychological well-being and connectedness for adolescent males at-risk for school failure. ^

Optimizing the Synthesis of AZN

Azulenyl nitrone (AZN) is a bright green compound that can be used to stain different compounds, including plastics. When these stained plastics are irradiated, as they commonly are in the sterilization of medical devices, AZN changes color from green to red, constituting a permanent change. This would make obsolete the current methods of radioactive labeling and maintain the integrity of medical equipment. Although a method of synthesis is already in place, the aim was to improve the yield significantly and find a more efficient and cost-effective procedure. Last year, the procedure used resulted in 18 to 20% of AZN synthesized at the most favorable conditions. With that in mind, this year modifications were done in the hopes of improving the yield. The solvent was changed to a mixture of isopropanol and triethylamine, a stronger base, and a catalytic amount of N-tertbutyl hydroxylamine hydrochloride was used (around 4 equivalents). The reaction time was also increased to 7 days, rather than 2. After several trials, the samples were run through column chromatography and the average yield was 70%, a much more promising result than that obtained last year. There is still research to be done to improve the technicalities of the procedure, including altering the amounts of N-tertbutyl hydroxylamine hydrochloride to try and obtain similar data with fewer amounts. This portion of the research will be done in the second half of the year. In the meantime, however, a novel and more efficient method of synthesis has been established for the production of AZN that can be potentially commercialized.
