Excess energy intake is recognised as a strong contributing factor to the global rise of being overweight and obese. The aim of this paper was to investigate if oral sensitivity to complex carbohydrate relates to ad libitum consumption of complex carbohydrate foods in a sample group of female adults. Participants’ ((n 51 females): age 23·0 (sd 0·6) years (range 20·0–41·0 years); excluding restrained eaters) sensitivity towards maltodextrin (oral complex carbohydrate) and glucose (sweet taste) was assessed by measuring detection threshold (DT) and suprathreshold intensity perception (ST). A crossover design was used to assess consumption of two different iso-energetic preload milkshakes and ad libitum milkshakes – (1) glucose-based milkshake, (2) maltodextrin-based milkshake. Ad libitum intake (primary outcome) and eating rate, liking, hunger, fullness and prospective consumption ratings were measured. Participants who were more sensitive towards complex carbohydrate (maltodextrin DT) consumed significantly more maltodextrin-based milkshake in comparison with less-sensitive participants (P = 0·01) and this was independent of liking. Participants who had higher liking for glucose-based milkshake consumed significantly more glucose-based milkshake in comparison with participants with lower hedonic ratings (P = 0·049). The results provide support regarding the role of the oral system sensitivity (potentially taste) to complex carbohydrate and the prospective to overconsume complex carbohydrate-based milkshake in a single sitting.

Background: Mindfulness-based cognitive therapy (MBCT) has evidence of efficacy in a range of populations, but few studies to date have reported on MBCT for treatment of anxious and depressive symptoms in Parkinson's disease (PD). Aims: The aim of this study was to examine the efficacy of modified MBCT in reducing symptoms of anxiety and depression and improving quality of life in PD. Method: Thirty-six individuals with PD were randomly assigned to either modified MBCT or a waitlist control. Changes in symptoms of anxiety, depression and quality of life were compared at group level using generalized linear mixed models and at individual level using reliable change analysis. Results: At post-treatment, there was a significant reduction in depressive symptoms for people undertaking modified MBCT at both group and individual levels compared with controls. There was no significant effect on anxiety or quality of life at the group level, although significantly more people had reliable improvement in anxiety after modified MBCT than after waitlist. Significantly more waitlist participants had reliable deterioration in symptoms of anxiety and depression than those completing modified MBCT. Most participants stayed engaged in modified MBCT, with only three drop-outs. Discussion: This proof-of-concept study demonstrates the potential efficacy of modified MBCT as a treatment for depressive symptoms in Parkinson's disease and suggests further research is warranted.

The Coleman Report

For this History of Education Quarterly Policy Forum, we look at the historical significance of the 1966 Coleman Report from several different perspectives. The four main essays published here originated as presentations for a session on “Legacies of the Coleman Report in US Thought and Culture” at the History of Education Society annual meeting in Providence, Rhode Island, in November 2016. Presenters for that session— Zoë Burkholder, Victoria Cain, Leah Gordon, and Ethan Hutt—went on to participate in an HES-sponsored session entitled “Currents in Egalitarian Thought in the 1960s and 1970s: The Coleman Report in American Politics, Media, and Social Science” at the Organization of American Historians meeting in New Orleans in April 2017. Thinking that their reflections on the reception and influence of the Coleman Report in different contexts would be of broad interest to HEQ readers, we asked members of the panel to comment on each other's papers and revise them for this Forum. We then invited Harvey Kantor of the University of Utah and Robert Lowe of Marquette University to write an introduction summarizing the origins and findings of the Coleman Report, along with their own assessment of what the presenters’ essays teach us about its long-term significance. What follows are Kantor and Lowe's Introduction, “What Difference Did the Coleman Report Make?,” together with substantive essays by Zoë Burkholder of Montclair State University, Victoria Cain of Northeastern University, Leah Gordon of Amherst College, and Ethan Hutt of the University of Maryland.

This article describes how disrupting the activities of suspected violent extremists has become an increasingly significant construct in the policy and practice of the Prevent strand of UK Counter-Terrorism. Informed by empirical data collected during semi-structured interviews with police officers involved in conducting disruptions and members of the communities where these occurred, blended with a limited amount of field observation, the analysis documents how and why a logic of disruption has assumed increasing prominence in counter terrorism work. In respect of police interventions in particular, implementing disruptions, rather than pursuing fully-fledged prosecutions, represents a pragmatic way of reconciling increasing demand with limited resources, as well as managing some of the difficulties of translating intelligence into legal evidence. Conceptualized in this way, the analysis positions disruption as a distinctive mode of crime prevention; one premised upon logics of near-event interdiction. As such, it is understood as rather different in its operations and functions to other forms of “early intervention” that are increasingly prominent in much contemporary crime prevention policy. By focusing upon how specific Prevent interventions are implemented and performed this analysis makes a particular contribution to our knowledge of counter terrorism work. This reflects the fact that most previous studies of Prevent and other countering violent extremism programs have provided analyses of community perceptions and reactions to policing and the policy frame, rather than the configuration of the interventions themselves.

In summer, 2011, we investigated suspected glyphosate-resistant (GR) kochia in three chem-fallow fields (designated F1, F2, F3, each farmed by a different grower) in southern Alberta. This study characterizes glyphosate resistance in those populations, based on data from dose–response experiments. In a greenhouse experiment, the three populations exhibited a resistance factor ranging from 4 to 6 based on shoot biomass response (GR50 ratios), or 5 to 7 based on survival response (LD50 ratios). Similar results were found in a field dose–response experiment at Lethbridge, AB, in spring 2012 using the F2 kochia population. In fall 2011, we surveyed 46 fields within a 20-km radius of the three chem-fallow fields for GR kochia. In the greenhouse, populations were screened with glyphosate at 900 g ae ha−1. Seven populations were confirmed as GR, the farthest site located about 13 km from the three originally confirmed populations. An additional GR population more than 100 km away was later confirmed. Populations were screened for acetolactate synthase (ALS)–inhibitor (thifensulfuron : tribenuron) and dicamba resistance in the greenhouse, with molecular characterization of ALS-inhibitor resistance in the F1, F2, and F3 populations. All GR populations were resistant to the ALS-inhibiting herbicide, but susceptible to dicamba. ALS-inhibitor resistance in kochia was conferred by Pro197, Asp376, or Trp574 amino acid substitutions. Based upon a simple empirical model with a parameter for selection pressure, calculated from weed relative abundance and glyphosate efficacy, and a parameter for seedbank longevity, kochia, wild oat, and green foxtail were the top three weeds, respectively, predicted at risk of selection for glyphosate resistance in the semiarid Grassland region of the Canadian prairies; wild oat, green foxtail, and cleavers species were predicted at greatest risk in the subhumid Parkland region. This study confirms the first occurrence of a GR weed in western Canada. Future research on GR kochia will include monitoring, biology and ecology, fitness, mechanism of resistance, and best management practices.

A newly designed, 100 mm2, silicon drift detector has been installed on an aberration-corrected scanning transmission electron microscope equipped with an ultra-high resolution pole piece, without requiring column modifications. With its unique, windowless design, the detector’s active region is in close proximity to the sample, resulting in a dramatic increase in count rate, while demonstrating an increased sensitivity to low energy X-rays and a muted tilt dependence. Numerous examples of X-ray energy dispersive spectrometry are presented on relevant materials such as AlxGa1−xN nanowires, perovskite oxides, and polycrystalline CdTe thin films, across both varying length scales and accelerating voltages.
