What can the lit lab do for you? a qualitative analysis of high school literacy lab participants
The purpose of the study is to document the changes in student progress, motivation, and achievement. The specific aim is to see what happens when students replace a traditional study hall with small group guided instruction in a literacy lab. Motivation profiles, goal setting, and reflection are all analyzed. The focus group of students demonstrated changes in how they viewed themselves as learners and in their academic endeavor to achieve goals. The implications for teaching in a literacy lab environment are discussed
Nachbauprobleme bei Apfelkulturen
Bei wiederholtem Anbau von Obstbäumen am gleichen Standort wird häufig verminderter Wuchs und reduzierter Ertrag beobachtet. Dieses Phänomen wird als Nachbauproblem oder Bodenmüdigkeit bezeichnet. Auch Schweizer Apfelproduzenten sind davon betroffen. Die ACW untersucht mögliche Ursachen
The effects of short-term fasting on quality of life and tolerance to chemotherapy in patients with breast and ovarian cancer: a randomized cross-over pilot study
Background This pilot trial aimed to study the feasibility and effects on
quality of life (QOL) and well-being of short-term fasting (STF) during
chemotherapy in patients with gynecological cancer. Methods In an
individually-randomized cross-over trial patients with gynecological cancer, 4
to 6 planned chemotherapy cycles were included. Thirty-four patients were
randomized to STF in the first half of chemotherapies followed by normocaloric
diet (group A;n = 18) or vice versa (group B;n = 16). Fasting started 36 h
before and ended 24 h after chemotherapy (60 h-fasting period). QOL was
assessed by the FACIT-measurement system. Results The chemotherapy-induced
reduction of QOL was less than the Minimally Important Difference (MID; FACT-G
= 5) with STF but greater than the MID for non-fasted periods. The mean
chemotherapy-induced deterioration of total FACIT-F was 10.4 ± 5.3 for fasted
and 27.0 ± 6.3 for non-fasted cycles in group A and 14.1 ± 5.6 for non-fasted
and 11.0 ± 5.6 for fasted cycles in group B. There were no serious adverse
effects. Conclusion STF during chemotherapy is well tolerated and appears to
improve QOL and fatigue during chemotherapy. Larger studies should prove the
effect of STF as an adjunct to chemotherapy. Trial registration This trial was
registered at clinicaltrials.gov: NCT01954836
ENTRAP and its potential interaction with European networks
AbstractENTRAP comprises a pan-European cooperation of leading scientific institutions and regulatory bodies in the field of nuclear-waste characterization and its quality assurance for the safe disposal of radioactive waste. Here, the scope of this cooperation is presented and explained and links or interfaces for a potential collaboration with partners fulfilling tasks of IDG-TP are pursued
Neoliberalism as a Political Rationality: Australian Public Policy Since the 1980s
Since the 1980s, a remarkable transformation has occurred in the rationale that informs public policy in Australia. This transformation reflects a fundamental change in the way national economies and populations are conceived by policy makers and has led to the emergence of new strategies of governance as a consequence. We argue that this change of direction in Australian public policy may be best thought of as a specific neoliberal political rationality. The first section of the paper outlines changes to conceptions of the economy and subjectivity which are associated with neoliberalism as a political rationality. The second part of the paper examines the articulation and implementation of neoliberalism in Australia over the last couple of decades
Tony Blair and John Howard: comparative predominance and 'Institution Stretch' in the UK and Australia
It has recently been argued that the UK premier enjoys a level of executive power unavailable to US presidents, but how does he or she compare to another prime minister operating within a broadly similar system? Commonalities of intra-executive influence and capacity exist under the premierships in the UK and Australia. Discrete institutional constraints and deviations are evident, but trends and similarities in resource capacity can be clearly identified. These include: the growth of the leaders' office; broadening and centralising of policy advice and media operations; and strengthening of the role and function of ministerial advisers. I contend that this amounts to 'institution stretch', with new structures, processes and practices becoming embedded in the political system by the incumbents. © 2007 The Author.

Power Versus Affiliation in Political Ideology
Posited motivational differences between liberals and conservatives have historically been controversial. This motivational interface has recently been bridged, but the vast majority of studies have used self-reports of values or motivation. Instead, the present four studies investigated whether two classic social motive themes—power and affiliation—vary by political ideology in objective linguistic analysis terms. Study 1 found that posts to liberal chat rooms scored higher in standardized affiliation than power, whereas the reverse was true of posts to conservative chat rooms. Study 2 replicated this pattern in the context of materials posted to liberal versus conservative political news websites. Studies 3 and 4, finally, replicated a similar interactive (ideology by motive type) pattern in State of the State and State of the Union addresses. Differences in political ideology, these results suggest, are marked by, and likely reflective of, mind-sets favoring affiliation (liberal) or power (conservative). </jats:p
A New Method to Address Unmet Needs for Extracting Individual Cell Migration Features from a Large Number of Cells Embedded in 3D Volumes
Background: In vitro cell observation has been widely used by biologists and pharmacologists for screening molecule-induced effects on cancer cells. Computer-assisted time-lapse microscopy enables automated live cell imaging in vitro, enabling cell behavior characterization through image analysis, in particular regarding cell migration. In this context, 3D cell assays in transparent matrix gels have been developed to provide more realistic in vitro 3D environments for monitoring cell migration (fundamentally different from cell motility behavior observed in 2D), which is related to the spread of cancer and metastases. Methodology/Principal Findings: In this paper we propose an improved automated tracking method that is designed to robustly and individually follow a large number of unlabeled cells observed under phase-contrast microscopy in 3D gels. The method automatically detects and tracks individual cells across a sequence of acquired volumes, using a template matching filtering method that in turn allows for robust detection and mean-shift tracking. The robustness of the method results from detecting and managing the cases where two cell (mean-shift) trackers converge to the same point. The resulting trajectories quantify cell migration through statistical analysis of 3D trajectory descriptors. We manually validated the method and observed efficient cell detection and a low tracking error rate (6%). We also applied the method in a real biological experiment where the pro-migratory effects of hyaluronic acid (HA) were analyzed on brain cancer cells. Using collagen gels with increased HA proportions, we were able to evidence a dose-response effect on cell migration abilities. Conclusions/Significance: The developed method enables biomedical researchers to automatically and robustly quantify the pro- or anti-migratory effects of different experimental conditions on unlabeled cell cultures in a 3D environment. © 2011 Adanja et al.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
