A Pilot Study of Bibliotherapy to Reduce Alcohol Problems among Patients in a Hospital Trauma Center

Because alcohol use plays a major role in many injuries that require hospital care, there is increasing interest in developing interventions to address alcohol problems among emergency department and trauma center patients. The aim of the current study was to extend past research on brief interventions by investigating the use of a self-help manual to treat problem drinkers in a hospital trauma center. Forty injured patients who were either intoxicated at the time of injury or screened positive for harmful drinking were randomly assigned to receive either a brief assessment and a self-help booklet with no more than 5 minutes clinician contact (bibliotherapy) or brief assessment only. Follow-up data obtained five months after hospital discharge indicated that patients in both conditions made significant reductions in drinking and associated negative consequences. There was a trend toward further treatment-seeking among those in the bibliotherapy condition (40% versus 13%). Results suggest that the provision of self-help materials to treat problem drinkers identified in a hospital trauma setting may not bring about behavior change beyond that observed following hospitalization and an assessment of drinking. Caution in the interpretation of results is warranted due to the small sample size

Manual for the Motivational Interviewing Skill Code (MISC)

Over years of using MISC 1 we have learned much about which categories were redundant or unreliable, and also about which processes are most important to the effectiveness of MI. The MISC has also helped us to clarify the points at which skill acquisition in MI is more challenging. Based on this experience, we have developed Version 2.0, which is intended to improve on the original MISC in reliability, efficiency, and relevance to training and clinical practice. A disadvantage of revising an instrument, of course, is that one must start over in demonstrating its reliability and validity. Although many strong features of MISC 1.0 have been retained, we have also made substantive changes that we believe will further strengthen this instrument. In the interim, while we are studying the characteristics of this new version, it may be desirable for some purposes to continue using MISC 1, which has known psychometric properties. Section A outlines the significant changes that have been introduced with MISC 2.0 and the rationale for these changes

Effect of Preanalytical Processing of ThinPrep Specimens on Detection of High-Risk Human Papillomavirus by the Aptima HPV Assay

Two important preanalytical protocols performed on liquid-based cytological specimens, namely, automated cytology processing and glacial acetic acid (GAA) treatment, may occur prior to the arrival of specimens in a molecular diagnostics laboratory. Ninety-two ThinPrep vials previously positive for high-risk human papillomavirus (HPV) via the Cervista HPV HR test were preselected and alternated with 92 previously negative ThinPrep vials. The specimen set was processed in a consecutive fashion by an automated cytology processor without fastidious decontamination precautions. Carryover potential was subsequently assessed by performance of the Aptima HPV assay on aliquots from reprocessed ThinPrep vials. All previously negative ThinPrep vials yielded a negative result following routine automated cytology processing, despite close proximity to known-positive ThinPrep vials. In separate experiments, aliquots from 236 ThinPrep vials were forwarded for tandem analysis with and without GAA treatment. Data from GAA- and mock-treated specimens generated by Aptima HPV were compared to correlate data generated by Cervista. A 99.2% concordance of Aptima HPV results from GAA-treated and mock-treated specimens was noted. This result differed from the concordance result derived from Cervista (91.5%; P \u3c 0.0002). Of the initially positive Cervista results, 21.9% reverted to negative following GAA treatment; the correlate value was 2.7% for Aptima HPV (P = 0.01). While deleterious effects of GAA treatment on genomic DNA were noted with Cervista (P = 0.0015), GAA treatment had no significant effects on Aptima HPV specimen signal/cutoff ratios or amplification of internal control RNA (P ≥ 0.07). The validity of an Aptima HPV result is independent of GAA treatment and routine automated cytology processing

Client Commitment Language During Motivational Interviewing Predicts Drug Use Outcomes

Client language from a motivational interview (MI) and drug use outcome were investigated. Interview videotapes of 84 drug abusers were coded for frequency and strength of utterances expressing commitment, desire, ability, need, readiness, and reasons to change or maintain their habit. Cluster analysis of proportion days abstinent (PDA) revealed 3 groups: high PDA at intake and follow-up (3, 6, 9, 12 months; maintainers); low intake PDA/high follow-up PDA (changers); and low intake PDA/low to moderate follow-up PDA (stragglers). Distinct group patterns emerged for commitment strength (CS) during MI. Clients dishonest in checklist self-report exhibited CS similar to stragglers. CS for client evaluation of a change plan predicted outcome PDA. CS was predicted by the strength of desire, ability, need, and reasons, but more strongly predicted outcome PDA, suggesting CS is a pathway for their influence on behavior

Spatiotemporal patterns of small for gestational age and low birth weight births and associations with land use and socioeconomic status

In addition to small for gestational age (SGA) and low birth weight at term (LBWT), critically ill cases of SGA/LBWT are significant events from outcomes and economic perspectives that require further understanding of risk factors. We aimed to assess the spatiotemporal distribution of locations where there were consistently higher numbers of critically ill SGA/LBWT (hot spots) in comparison with all SGA/LBWT and all births. We focused on Edmonton (2008-2010) and Calgary (2006-2010), Alberta, and used a geographical information system to apply emerging hot spot analysis, as a new approach for understanding SGA, LBWT, and the critically ill counterparts (ciSGA or ciLBWT). We also compared the resulting aggregated categorical patterns with proportions of land use and socioeconomic status (SES) using Spearman correlation and logistic regression. There was an overall increasing trend in all space-time clusters. Whole period emerging hot spot patterns among births and SGA generally coincided, but SGA with ciSGA and LBWT with ciLBWT did not. Regression coefficients were highest for low SES with SGA and LBWT, but not with ciSGA and ciLBWT. Open areas and industrial land use were most associated with ciLBWT but not with ciSGA, SGA, or LBWT. Differences in the space-time hot spot patterns and the associations with ciSGA and ciLBWT indicate further need to research the interplay of maternal and environmental influences. We demonstrated the novel application of emerging hot spot analysis for small newborns and spatially related them to the surrounding environment

Nitrogen cycle disruption through the application of de-icing salts on upland highways

It is hypothesized that episodic introductions of road salt severely disrupt the soil nitrogen cycle at a range of spatial and temporal scales. A field-scale study has confirmed impacts on the nitrogen cycle in soil, soil solution and river samples. There is evidence that ammonium-N retention on cation exchange sites has been reduced by the presence of sodium ions, and that ammonium-N has been flushed from the exchange sites. Increases in soil pH have been caused in naturally acidic uplands. These have enhanced mineralization of organic-N, especially nitrification, leading to a reduction in the mineralizable-N pool of roadside soils. There is evidence to support the hypothesis that organic matter content has been lowered over decades either through desorption or dispersal processes. Multiple drivers are identified that contribute to the disruption of nitrogen cycling processes, but their relative importance is difficult to quantify unequivocally. The influence of road salt on soil and soil solution declines with distance from the highway, but impacts on water chemistry in a local stream are still strongly evident at some distance from the road

Communication in the Third Dimension: Song Perch Height of Rivals Affects Singing Response in Nightingales

Many animals use long-range signals to compete over mates and resources. Optimal transmission can be achieved by choosing efficient signals, or by choosing adequate signalling perches and song posts. High signalling perches benefit sound transmission and reception, but may be more risky due to exposure to airborne predators. Perch height could thus reflect male quality, with individuals signalling at higher perches appearing as more threatening to rivals. Using playbacks on nightingales (Luscinia megarhynchos), we simulated rivals singing at the same height as residents, or singing three metres higher. Surprisingly, residents increased song output stronger, and, varying with future pairing success, overlapped more songs of the playback when rivals were singing at the same height than when they were singing higher. Other than expected, rivals singing at the same height may thus be experienced as more threatening than rivals singing at higher perches. Our study provides new evidence that territorial animals integrate information on signalling height and thus on vertical cues in their assessment of rivals

Stone cladding techniques in Modern Architecture 1922-1942

Leggere il progetto del Moderno e le sue culture costruttive in relazione alla storia e allo sviluppo della tecnologia, consente di esplorare alcuni aspetti dell’Architettura Moderna in Europa. Oltre alla più famosa, e maggiormente studiata, triade dei materiali ‘moderni’ – l’acciaio, il calcestruzzo e il vetro – la pietra ha svolto un importante ruolo nella definizione sia dello stile che della costruzione moderna. La costruzione in pietra è stata sempre associata alla tradizione e quindi deliberatamente dimenticata dal Movimento Moderno, durante la fase cruciale della modernizzazione della società e quindi dell’architettura e della costruzione. La pietra tuttavia testimonia la delicata transizione dalla tradizionale arte del costruire alle nuove tecnologie. La ricerca ha studiato l’evoluzione delle tecniche costruttive in pietra in Francia ed in Italia, durante gli anni ’20 e ’30, in relazione alle nuove tecniche industrializzate e i linguaggi delle avanguardie. La ricerca è partita dallo studio dei manuali, delle riviste e dei progetti presentati sulle loro pagine. In Italia e in Francia il rivestimento in pietra si afferma come un sistema costruttivo ‘razionale’, dove la costruzione moderna converge lentamente verso nuove soluzioni; questo sistema ha avuto negli anni ’20 e ’30 un ruolo centrale, nel quale è stato possibile un dialogo, senza contraddizioni, tra i materiali ‘moderni’ e la pietra. L’evoluzione dalle tradizionali tecniche costruttive verso i nuovi sistemi tecnologici, ha determinato una nuova costruzione in pietra che è alla base di una modernità che non rifiuta questo materiale tradizionale, ma lo trasforma secondo i nuoci principi estetici.Reading the project of the Modern and its constructive cultures in relation to the historical conditions and the technology, allows exploring some aspects of Modern Architecture in Europe. Besides the traditional, more studied and known triad of "moderns" materials, steel, concrete and glass, the stone also played an important role, in the definition both of "modern construction and modern style". The construction in stone was always associated with the tradition and then forgotten by the Modern Movement, during the crucial phase of society’s "modernization" and therefore its architecture and construction. The stone however explains this delicate transition from the traditional art of building in stone to the new technologies. The research studies this evolution of construction techniques in stone in France and Italy during the '20s and '30s, related to the new industrialized construction and the avant-garde languages. It begins with the study of technical manuals, the reviews and the projects presented on its pages. The stone cladding, in Italy and France, grows as a model of constructive rationality, where "modern" building techniques slowly converge toward to new solutions. The modern cladding in stone during the '20s '30s has a central role, where the dialogue is possible, without contradiction, between the materials so-called "modern" and the stone. The evolution from traditional techniques to new technological systems determined a new construction in stone that is the basis of modernity and that doesn’t reject this traditional material, but transforms it according to the new aesthetic principles

Optical control of 4f orbital state in rare-earth metals

Information technology demands continuous increase of data-storage density. In high-density magnetic recording media, the large magneto-crystalline anisotropy (MCA) stabilizes the stored information against decay through thermal fluctuations. In the latest generation storage media, MCA is so large that magnetic order needs to be transiently destroyed by heat to enable bit writing. Here we show an alternative approach to control high-anisotropy magnets: With ultrashort laser pulses the anisotropy itself can be manipulated via electronic state excitations. In rare-earth materials like terbium metal, magnetic moment and high MCA both originate from the 4f electronic state. Following infrared laser excitation 5d-4f electron-electron scattering processes lead to selective orbital excitations that change the 4f orbital occupation and significantly alter the MCA. Besides these excitations within the 4f multiplet, 5d-4f electron transfer causes a transient change of the 4f occupation number, which, too, strongly alters the MCA. Such MCA change cannot be achieved by heating: The material would rather be damaged than the 4f configuration modified. Our results show a way to overcome this limitation for a new type of efficient magnetic storage medium. Besides potential technological relevance, the observation of MCA-changing excitations also has implications for a general understanding of magnetic dynamics processes on ultrashort time scales, where the 4f electronic state affects the angular momentum transfer between spin system and lattice.Comment: Manuscript (14 pages, 3 figures) and Supplementary Information (22 pages, 9 figures
