Spatial and temporal pulse shaping for lateral and depth resolved two-photon excited fluorescence contrast

We report combined temporal and spatial laser pulse shaping to perform lateral and depth dependent two-photon excited fluorescence of dyes. For generating the specific spatially and temporally phase tailored pulses a temporal pulse shaper and a subsequent spatial pulse shaper are employed. Simultaneous spatial and temporal shaping is presented for two-photon excited fluorescence by applying temporal third order phase functions on spatially different light field components. Moreover, the prospects of spatial shaping are demonstrated by applying various lateral two-photon fluorescence pattern. In particular, a depth dependent excitation of different dyes is performed which leads to a high axially resolved fluorescence contrast. The introduced spatial and temporal shaping technique provides new perspectives for biophotonic imaging applications

A Place for the Church within Professional Psychology

There are various reasons why Christian psychologists may resist fully participating in a church community. Among these are historic tensions between science and religion, the complexity of multiple role relationships, cynicism related to clients\u27 negative experiences in religious communities, and differing perspectives on attributions and human nature. Despite these obstacles, there are compelling reasons for psychologists to remain involved in church. Eight of these reasons are described--clustered into professional, relational, and transformational domains--and implications discussed

Satisfaction with Clinical Training in Christian Psychology Doctoral Programs: Survey Findings and Implications

Perceptions of clinical training at seven explicitly Christian doctoral programs in clinical psychology were assessed with a satisfaction survey. A total of 228 students, 128 alumni, and 34 faculty completed the online questionnaire that entailed 20 satisfaction items. Factor analysis revealed three factors: Supervision and Support, Clinical Placements, and Professional Development. Of these, Supervision and Support received the highest satisfaction ratings and Professional Development the lowest. Overall, clinical training was perceived quite positively by respondents, and more highly than research training ratings reported in a previous study. Alumni and faculty reported greater satisfaction than current students

Energy relaxation and triplet formation

We combined femtosecond (fs) VIS pump–IR probe spectroscopy with fs VIS pump–supercontinuum probe spectroscopy to characterize the photoreaction of the hexacoordinated Al(tpfc-Br8)(py)2 in a comprehensive way. Upon fs excitation at ∼400 nm in the Soret band, the excitation energy relaxes with a time constant of (250 ± 80) fs to the S2 and S1 electronic excited states. This is evident from the rise time of the stimulated emission signal in the visible spectral range. On the same time scale, narrowing of broad infrared signals in the C=C stretching region around 1500 cm−1 is observed. Energy redistribution processes are visible in the vibrational and electronic dynamics with time constants between ∼2 ps and ∼20 ps. Triplet formation is detected with a time constant of (95 ± 3) ps. This is tracked by the complete loss of stimulated emission. Electronic transition of the emerging triplet absorption band overlaps considerably with the singlet excited stateabsorption. In contrast, two well separated vibrational marker bands for triplet formation were identified at 1477 cm−1 and at 1508 cm−1. These marker bands allow a precise identification of triplet dynamics in corrole systems

The Vibrational Spectrum of the hydrated Alanine-Leucine Peptide in the Amide region from IR experiments and First Principles Calculation

We have combined infrared (IR) experiments with molecular dynamics (MD) simulations in solution at finite temperature to analyse the vibrational signature of the small floppy peptide Alanine-Leucine. IR spectra computed from first- principles MD simulations exhibit no distinct differences between conformational clusters of alpha-helix/beta-sheet-like folds with different orientations of the bulky leucine side chain. All computed spectra show two prominent bands, in good agreement with the experiment, that are assigned to the stretch vibrations of the carbonyl and carboxyl group, respectively. Variations in band widths and exact maxima are likely due to small fluctuations in the backbone torsion angles

Efficient chaining of seeds in ordered trees

We consider here the problem of chaining seeds in ordered trees. Seeds are mappings between two trees Q and T and a chain is a subset of non overlapping seeds that is consistent with respect to postfix order and ancestrality. This problem is a natural extension of a similar problem for sequences, and has applications in computational biology, such as mining a database of RNA secondary structures. For the chaining problem with a set of m constant size seeds, we describe an algorithm with complexity O(m2 log(m)) in time and O(m2) in space

Technology and Independent Practice: Survey Findings and Implications

Today’s rapid rate of technology change introduces both opportunities and challenges for psychologists. A Technology and Practice Questionnaire was sent to 1000 psychologists in independent practice, half of whom were contacted by e-mail and the other half by U.S. mail. A total of 237 of the 433 deliverable surveys sent by U.S. mail were returned (54.7% response rate), but only 49 of the 458 deliverable surveys sent by e-mail (12.9% response rate). Respondents were asked to rate the frequency of 51 behaviors in their practice and to indicate whether the behavior is ethical. The results suggest a relatively low rate of technology use among independent practitioners and a high degree of ethical uncertainty regarding the use of various technologies in practice. Implications for training and practice are considered

Feasibility Study of Back2School, a Modular Cognitive Behavioral Intervention for Youth With School Attendance Problems

There is large heterogeneity among youth with school attendance problems (SAPs). For this reason, protocols for the treatment of SAPs need to be flexible. Back2School (B2S) is a new manual-based, modular transdiagnostic cognitive behavioral intervention to increase school attendance among youth with SAPs. It also aims to increase the self-efficacy of these youth and their parents. B2S includes evidence-based modules addressing youth anxiety, depression, and behavior problems, together with modules focused on parent guidance and school consultation. The current study examined the feasibility of evaluating B2S in an randomized controlled trial and acceptability of the B2S program in a non-randomized trial, including both qualitative and quantitative data, in preparation for a randomized controlled trial of its effectiveness. Youth, parents, and teachers completed questionnaires at baseline, post-intervention, and follow-up. School attendance data were collected from school registers. Twenty-four youth with a SAP (defined as more than 10% absenteeism during the last 3 months) were recruited from primary and lower secondary schools in Aarhus Municipality, Denmark. Their parents also participated in B2S. Two of the 24 families withdrew during the intervention, after sessions two and six respectively. Of the remaining 22 families, 19 (86%) completed all 10 sessions. Parents and youth rated their satisfaction with B2S as high, and high levels of satisfaction were maintained 1 year after the intervention. Teacher satisfaction was lower than that of youth and parents, but the majority found the school's participation in the intervention helpful. Preliminary evaluation of intervention outcomes showed significant increase in school attendance and decrease in psychological symptoms, as well as a significant increase in self-efficacy for both youth and parents. Based on this feasibility data, adaptations were made to the B2S manual and study procedures prior to commencement of a randomized controlled effectiveness trial. The main adaptation to the manual was to increase school consultation. The main procedural adaptation was to broaden recruitment. Furthermore, it was necessary to increase level of staffing by psychologists because treatment delivery was more time consuming than expected.Pathways through Adolescenc

The use of frequency diagrams in the survey of resistance to pesticides in ticks in southern Africa

A method whereby resistance data can be analysed by means of frequency distributions is described. This method established that Rhipicephalus appendiculatus and R. evertsi evertsi show either little or only developing resistance to the pesticides chlorfenvinphos and dioxathion. Boophilus spp., however, show more instances and higher levels of resistance to these 2 pesticides.This article has been scanned in colour with a HP Scanjet 5590; 300dpi.
