Magneto-acoustic resonance in a non-uniform current carrying plasma column

The forced radial magneto-acoustic oscillations in a plasma column with nonuniform mass density and temperature are investigated. It turns out that the oscillations have a resonant character similar to that of the magneto-acoustic oscillations in a uniform plasma column. The properties of the axial and azimuthal components of the oscillating magnetic field are discussed in detai

On re-normalization in the theory of weak turbulence in plasmas

The paper compares the methods of re-normalization introduced by the Dupree—Weinstock theory of turbulence with those in the theories of Kadomtsev, Rudakov and Tsytovich. It is shown to what extent they are equivalen

Organic retailing development in Europe

Overall development The organic retailing sector in Europe profited from the positive organic food market developments in 2007. The organic retail sector in Europe represents app. 5 – 25% of the total organic market country by country. In most countries, the organic retail sector grew proportionally to the general organic market. Organic retail sector has gained more significance in some Southern and Eastern European and Scandinavian countries. New enterprises or branches of specialized organic retailers emerge on a nearly constant basis in Europe

Neuromodulation to Enhance Attention Training in Socially Anxious Adolescents

Anxiety and its disorders are prevalent and impairing in adolescents, often following a chronic course, and are associated with heightened prospective risk of depressive disorders, substance use disorders, and suicidal behaviors. Traditional interventions such as cognitive behavioral therapy (CBT) have yielded response rates that highlight the critical need to examine treatment outcome moderators in underrepresented populations (i.e., Latino youth), as well as identify and evaluate innovative and alternative interventions that are brief, efficacious, and grounded in neuroscience. In a series of three manuscripts, this dissertation project presents findings on moderators of CBT outcomes in Latino youth (Chapter II) and explores novel and alternative treatments for social anxiety by targeting neural processes subserving attention to social threat in socially anxious youth (Chapters III and IV). Findings from Chapter II highlight the implications for selecting treatment targets and delivery format in the treatment of anxiety disorders in Latino youth, and the need to identify optimal ways to involve less acculturated Latino parents when receiving parent-involved CBT to maximize treatment outcomes. Findings from Chapter III support the feasibility and acceptability of attention bias modification (ABM) and transcranial direct current stimulation (tDCS) as novel treatment modalities. Lastly, while findings from Chapter IV did not provide evidence of an enhancement effect of tDCS on state anxiety levels or neural processes subserving attention to social threat, it provides further support for the feasibility of using tDCS as an augment to ABM in older adolescents with elevated social anxiety. It also suggests that later stage attentional processes involved in the regulation and control of attention might be malleable in response to ABM and/or tDCS. The collection of manuscripts presented in this portfolio provide insights into the treatment of youth anxiety, for both traditional approaches (i.e., CBT) and innovative and alternative approaches (i.e., ABM and tDCS). It further highlights the importance of advancing understanding of mechanisms of change in both traditional and novel treatments for youth anxiety

How the organic retailers cope with the economic downturn

During 2009, the organic market experienced an overall slowdown in growth, but no dramatic decline - Markets hardest hit by economic downturn: UK - Markets, where the organic shops were not doing very well: CZ, HU, Switzerland - Therefore important: Try new concepts: organic+fair, organic+regional, organic to go, shop and eat, organic+glamou

Who are the Elis of Today? Examining the Adults Present During the Religious Identity Development of Catholic-Raised Youth

Given that a large percentage of former-Catholic adults report leaving the Church before reaching adulthood, and the percentages of Catholic-raised youth retaining their religious identity into adulthood are decreasing, a pressing question currently facing the modern Catholic Church is how to minister to, and retain, Catholic-raised adolescents into adulthood. Current religious and secular literature suggests that adults (both parental and non-parental) may play a crucial role in youths’ religious identity development. However, who these adults are and how their presence influences the experience of growing up Catholic is unexplored in the current literature. In depth oral history narrative interviews were conducted with 24 Catholic-raised young adults; 12 who identify as Currently-Catholic and 12 who identify as Previously-Catholic. During these interviews, participants were asked to describe their experiences growing up Catholic and how they arrived at their current religious identity. Participants were also asked to focus their narrative on the adults they believe played a role in their religious identity development. Transcribed interviews were coded using modified grounded theory open coding strategies. Results include a list of adults present during the religious identity development process of Catholic-raised youth and themes related to characteristics and behaviors common to these adults. In addition, comparisons were drawn between types of adults, adult characteristics and adult behaviors between the two religious identity groups. In total, the 24 participants described 275 adults (M = 12.54 per participants, range = 3-20) during their interviews. Qualitative analysis fit these adults into six adult types: family adults, parish adults, school adults, religious event adults, large groups/communities of adults, and other adults (i.e., adults not met in any of the previous five settings). When discussing the adults present in their religious identity narratives, the characteristics participants felt influenced their religious identity development fell into four thematic categories: intelligence/lacking knowledge, engaging/ unengaging personality, approachable/unapproachable, and authentic/ disingenuous. Finally, behaviors participants felt influenced their religious identity development fell into six thematic categories: provided unconditional support versus conditional support, facilitated/had discussions about religion versus lacked/discouraged religious conversations, taught about the Catholic religion versus taught incorrect religious information, did or did not model a Catholic lifestyle, respected or disrespected other religions, and connected youth to Catholic experiences/people versus negative connections to Catholic activities. Quantitative analysis using the Mann-Whitney-U test found Currently-Catholic mentioned a significantly higher median number of religious event adults than their Previously-Catholic counterparts. Currently-Catholics also mentioned a significantly higher median number of adults who exhibited the authentic personality characteristic while Previously-Catholic participants mentioned a significantly higher median number of adults who exhibited the unapproachable personality characteristic. Currently-Catholic participants mentioned significantly higher median numbers of adults who exhibited the positive behavior: facilitated/ had discussions about religion. Previously-Catholic participants mentioned significantly higher median numbers of adults who exhibited the negative behaviors: provided conditional support, lacked/discouraged religious conversations, did not model a Catholic lifestyle, and negative connections to Catholic activities. This dissertation aimed to add to the limited literature regarding the religious identity formation of Catholic-raised youth, inform educational ministry and outreach strategies, and discuss the applicability and similarities of secular supportive adult behaviors in a religious setting
