15Md158: Excavations and Lithic Analysis of a Late Archaic/Early Woodland Lithic Workshop Site in Meade County, Kentucky.

This thesis describes archaeological investigations carried out at 15Md158, a prehistoric lithic workshop site in Meade County, Kentucky. Although there has been a wide range of diagnostic projectile points as well as some late radiocarbon dates recovered from the site had been identified as a mostly Late Archaic special purpose site where mostly late-stage lithic reduction took place. The goals of this project were to develop a more secure chronology for the site, document a change in the use of the site in order to relate it to changes in mobility patterns of those who utilized the site, and document if different areas of the site were used for different stages of the lithic reduction process. In order to answer these questions a series of five test units were excavated in the areas of the site that contained the greatest densities of lithic artifacts. The artifact assemblage that was collected was subjected to a production trajectory analysis that was used to look for vertical and horizontal patterning. The artifact assemblage from 15Md158 was found to reflect a long production trajectory, meaning that the full range of the lithic reduction process took place at this site. This study was not successful in finding vertical or horizontal patterning in the artifact assemblage, although it was successful in developing a more secure chronology for the site. The investigation found that the site was most heavily utilized during the Late Archaic and Early Woodland periods. Furthermore, this study found that the site may be associated with a network of lithic manufacturing sites in the region that were used for the specialized manufacture of trade and ritual artifacts from Wyandotte, a blue-gray chert which was heavily traded during the time periods the periods that the site was utilized

Rationale for Utilization of Hydrogel Rectal Spacers in Dose Escalated SBRT for the Treatment of Unfavorable Risk Prostate Cancer

In this review we outline the current evidence for the use of hydrogel rectal spacers in the treatment paradigm for prostate cancer with external beam radiation therapy. We review their development, summarize clinical evidence, risk of adverse events, best practices for placement, treatment planning considerations and finally we outline a framework and rationale for the utilization of rectal spacers when treating unfavorable risk prostate cancer with dose escalated Stereotactic Body Radiation Therapy (SBRT)

'Is your city pretty anyway?' Perspectives on graffiti and the urban landscape

Drawing on survey and focus group research completed in New Zealand in 2009 this article examines young peoples’ perspectives on graffiti and tagging. The results further demonstrate that graffiti writing is an activity invested with considerable cultural meaning by many of those engaged in it and that their understanding of graffiti is considerably at odds with prevailing political, media and policy discourse that sees it purely in terms of criminal damage and antisocial behaviour. While graffiti can be conceptualised as an alternative way of ‘reading’ urban space, the results of this study show that writers recognised that graffiti had damaging consequences and was inappropriate in some contexts. Graffiti was not simply nihilistic destructive behaviour but one in which perceptions of criminality were leavened by aesthetic judgements and the allure and excitement of potential local celebrity

Would you use it with a seal of approval? Important attributes of 2,4-dinitrophenol (2,4-DNP) as a hypothetical pharmaceutical product

Background2,4-Dinitrophenol (2,4-DNP) is an effective but highly dangerous fat burner, not licensed for human consumption. Death cases reported for 2,4-DNP overdose, particularly among young adults, have raised concerns about the ineffective regulatory control, lack of education and risks associated with impurity, and the unknown concentration of 2,4-DNP purchased on the Internet.MethodsUsing a sequential mixed method design and based on a hypothetical scenario as if 2,4-DNP was a licensed pharmaceutical drug, first we conducted a qualitative study to explore what product attributes people consider when buying a weight-loss aid. Focus group interviews with six females and three males (mean age = 21.6 ± 1.8 years) were audiorecorded, transcribed verbatim, and subjected to thematic analysis. Sixteen attributes were identified for the Best–Worst Scale (BWS) in the quantitative survey with 106 participants (64% female, mean age = 27.1 ± 11.9 years), focusing on 2,4-DNP. Demographics, weight satisfaction, and risk for eating disorder data were collected.ResultsIn contrast to experienced users such as bodybuilders, our study participants approached 2,4-DNP cautiously. Attributes of 2,4-DNP as a hypothetical weight-loss drug comprised a range of desirable and avoidable features. Of the 16 selected attributes, BWS suggested that long-term side effects were the most and branding was the least important attribute. Effectiveness and short-term side effects were also essential. Those in the >25 year group showed least concerns for legality. Neutral BWS scores for cost, treatment, degree of lifestyle changes required, and specificity required for the hypothetical weight-loss drug to be effective were likely caused by disagreement about their importance among the participants, not indifference.ConclusionWith advances in research, 2,4-DNP as a pharmaceutical drug in the future for treating neurodegenerative diseases and potentially for weight loss is not inconceivable. Caution is warranted for interpreting the BWS scores. Owing to the difference in what data represent at individual vs. population levels, with pooled data, the method correctly identifies attributes by which most people are satisfied but misrepresents attributes that are individually very important but not universally agreed. Whilst this may be an advantage in marketing applications, it limits the utility of BWS as a research tool

The daily association between affect and alcohol use: a meta-analysis of individual participant data

Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess affect and the number of alcoholic drinks consumed. Results indicate that people are not more likely to drink on days they experience high negative affect, but are more likely to drink and drink heavily on days high in positive affect. People self-reporting a motivational tendency to drink-to-cope and drink-to-enhance consumed more alcohol, but not on days they experienced higher negative and positive affect. Results were robust across different operationalizations of affect, study designs, study populations, and individual characteristics. These findings challenge the long-held belief that people drink more alcohol following increases in negative affect. Integrating these findings under different theoretical models and limitations of this field of research, we collectively propose an agenda for future research to explore open questions surrounding affect and alcohol use.The present study was funded by the Canadian Institutes of Health Research Grant MOP-115104 (Roisin M.

The development and preliminary psychometric properties of the Values Wheel

© 2019 Association for Contextual Behavioral Science Background: In Acceptance and Commitment Therapy (ACT), personal values function as motivational guideposts for behavior change and adaptive functioning. The continued empirical progress of this process-based therapy necessitates the development and evaluation of measures of values-directed behavior. This study reports on the preliminary psychometric properties of the Values Wheel: a new psychometric instrument designed and manufactured to provide an idiographic and weighted index of clients’ values-directed behavior. Method: One hundred fifty adults attended an assessment session on an individual basis to complete a values card sort task, Values Wheel and questionnaire measures of positive mental health, psychological distress and ACT processes. To investigate temporal stability, 39 participants completed two subsequent assessment sessions – each separated by a two-week interval. Results: The Values Wheel demonstrated evidence of temporal stability with large correlations between the scores obtained on the three occasions. Correlations with indices of valued living provided preliminary support for the measure's construct validity, whereas criterion-related validity was partially supported by correlations with positive mental health and stress. Conclusions: These findings provide preliminary support for the psychometric properties of the Values Wheel. Notwithstanding this study's limitations, the Values Wheel may hold potential as a measure of values-directed behavior with a broad scope of application in diverse contexts and languages
