Predictors of painkiller dependence among people with pain in the general population

Aims: Self-medication with painkillers is widespread and increasing, and evidence about influences on painkiller dependence is needed to inform efforts to prevent and treat problem painkiller use. Design: Online questionnaire survey. Participants: People in the general population who had pain and used painkillers in the last month (n=112). Measurements: Pain frequency and intensity, use of over-the-counter and prescription painkillers, risk of substance abuse (SOAPP scale), depression, anxiety, stress, alexithymia, pain catastrophizing, pain anxiety, pain self-efficacy, pain acceptance, mindfulness, self-compassion, and painkiller dependence (Leeds Dependence Questionnaire). Findings: In multiple regression, the independent predictors of painkiller dependence were prescription painkiller use (ß 0.21), SOAPP score (ß 0.31), and pain acceptance (ß -0.29). Prescription painkiller use mediated the influence of pain intensity. Alexithymia, anxiety and pain acceptance all moderated the influence of pain. Conclusions: The people most at risk of developing painkiller dependence are those who use prescription painkillers more frequently, who have a prior history of substance-related problems more generally, and who are less accepting of pain. Based on these findings, a preliminary model is presented with three types of influence on the development of painkiller dependence: a) pain leading to painkiller use, b) risk factors for substance-related problems irrespective of pain, and c) psychological factors related to pain. The model could guide further research among the general population and high risk groups, and acceptance-based interventions could be adapted and evaluated as methods to prevent and treat painkiller dependence.The Leonardo Da Vinci Lifelong Learning Programme funded Joana Duarte’s graduate research placement at the University of Derb

Identifying Student Success at a Land Grant Institution

Many higher education institutions use admission criteria to match students with the educational requirements of the institution, thereby increasing the level of success of their students and allocating limited enrollment space in some cases. This study uses two different approaches to identify the affect students’ background characteristics have on first year cumulative GPA, and whether differences exist in the impact of high school grades on success in their first year in college between high schools in the state of Washington. Results show that students’ particular high schools systematically perform better or worse than the model predicts, holding the other characteristics of the students constant including their high school GPA. This suggests the same GPA from different schools is indicating different levels of preparedness, either reflecting different curriculum available or taken by a student, or grade inflations differences across schools.Higher education, inflation, student success, Teaching/Communication/Extension/Profession, I23,

CONSUMER POTATO DEMAND

Changes in consumer demographics, socioeconomic conditions, lifestyles, food tastes, and health and nutrition concerns have been associated with shifting food purchase patterns. This article focuses on potato purchase decisions and consumption, using a sample of Washington households. The results suggest that potato purchases are affected by factors such as product quality and price but not availability of point-of-purchase information. Reported changes in fresh and processed potato consumption appeared to be related to concerns with health and nutrition and demand for convenience. These findings have implications for the potato industry in developing new products and marketing strategies.Demand and Price Analysis,

An atlas of emission line fluxes of planetary nebulae in the 1150-3200 A region

Emission line fluxes for 28 planetary nebulae are presented. The nebulae were chosen to cover a wide range of excitation classes, apparent diameters, location in the sky, and types of central stars. All objects were observed in the low dispersion mode of the IUE spectrographs, using the large entrance aperture

The Effects of Zinc Sulphate, Manganese Sulphate, and Iron Sulphate on the Lead Storage Cell.

The lead storage battery as it is used today is made up of the pasted type plates of lead dioxide, the anode, and sponge lead, the cathode, and wooden or hard rubber separators, which serve to insulate these from one another. In manufacturing these, it is desirable to keep them free from impurities

Multi-color carrier-envelope-phase stabilization for high-repetition-rate multi-pulse coherent synthesis

Using a zero-offset carrier-envelope locking technique, we have synthesized an octave-spanning composite frequency comb exhibiting 132-attosecond timing jitter between the constituent pulses over a one-second observation window. In the frequency domain, this composite comb has a modal structure and coherence which are indistinguishable from those of a comb that might be produced by a hypothetical single mode locked oscillator of equivalent bandwidth. The associated phase stability enables the participating multi-color pulse sequences to be coherently combined, representing an example of multi-pulse synthesis using a femtosecond oscillator
