Can the onset of type 2 diabetes be delayed by a group-based lifestyle intervention? A randomised control trial

This study was a randomised control trial with a waiting control group. It was designed to evaluate the effectiveness of a 6-month, group-based diabetes prevention programme, The Healthy Living Course and assess whether participation in the programme led to changes in modifiable risk factors for type 2 diabetes among an already at-risk pre-diabetic population. Individuals designated at risk for diabetes by their general practitioners (GPs) were screened using an Oral Glucose Tolerance Test. Volunteers (N = 307) with pre-diabetes were assigned to an intervention or wait-control group in the ratio of approximately 2 : 1. The sample was pre-tested on biochemical, anthropometric and self-report behavioural, cognitive and mood variables and post-tested either at the end of the educational/support-based lifestyle programme or the end of the wait period. The intervention group significantly improved their diabetes knowledge, motivation to change, positive affect, healthy eating and activity levels and showed significantly greater reductions in weight, body mass index, waist circumference, diastolic blood pressure and fasting plasma glucose in comparison with controls. The intervention group also changed their diagnostic status from pre-diabetes to non-diabetes at a greater rate than the wait group (43% vs. 26%) who received standard care from their GPs.     

Does delayed onset muscle soreness affect the biomechanical variables of the drop vertical jump that have been associated with increased ACL injury risk? A randomised control trial

IntroductionDelayed onset muscle soreness (DOMS) and Anterior Cruciate Ligament (ACL) injuries are both prevalent in sport. It is currently unknown whether DOMS increases ACL injury risk.AimThis study aimed to provide preliminary insight on whether DOMS affects ACL injury risk by investigating whether DOMS affects the biomechanical variables of the DVJ that have been identified as risk factors for future ACL injury.MethodsThis was a randomised control trial involving 32 active individuals aged 18–35 years, with no history of ACL injury. Participants underwent two sessions of force-plate testing and 3D motion analysis of the drop vertical jump (DVJ). The DVJ was chosen as it has been investigated prospectively for association with future ACL injury. Initial testing was followed by randomisation to DOMS or control group. The DOMS group underwent a DOMS-inducing exercise protocol, the control group did not. Both groups were re-tested 48 h after initial testing. Five variables of the DVJ that have been associated with future ACL injury were chosen for analysis - peak knee flexion angle, peak vertical ground reaction force, ground contact time, peak knee abduction angle & peak knee abduction moment. Between-group differences were compared using a two-way mixed analysis of variance; alpha level set to 0.05.ResultsDOMS was successfully induced in all participants of the DOMS group however no statistically significant group x time interactions were found for any of the five variables analysed.ConclusionsDOMS did not affect the biomechanical variables of the DVJ that have been associated with future ACL injury. By extension, this may suggest that DOMS might not affect ACL injury risk. However, it is also possible that certain attributes of the DVJ meant that any effect of DOMS was simply unable to be quantified, even if an effect existed. All considered, our position is that conclusion cannot be drawn from this study alone on whether DOMS affects ACL injury risk. Further research is required.     

Can there be a science of the symbolic?

Science means not just 'knowing', but knowing verified by replicability. Science is particularly hard to bring to depth psychology because the individual uniquenesses that can't be repeated are what make people most deeply themselves. Everyone, including the analytic investigator, however, has a science, in the sense of a world-view that is replicated by experience. Jung offered hermeneutics as an alternative mode to science for getting to know the psychological subject. But as Heidegger emphasized, hermeneutics always begins with the projection of a world-view, i.e., the science of the would-be interpreter. In the analytic situation, dialogue is available to test the world-view and enlarge its horizon, in accord with Gadamer's expansion of hermeneutics, 'the classical discipline concerned with the art of understanding texts', into a method of inquiry open to the possibilities of otherness. An example is given from an analytic training seminar, in which the author began by projecting his version of the theory of psychological types onto the dream material a candidate offered in response to the seminar. A dialogue with the candidate ensued which enabled the teacher to correct his original, somewhat rigid, application of his scientific viewpoint. In such a dialogue, psyche emerges as the final interpreter of what is, generating hypotheses that can fruitfully be applied to the understanding of other cases.     

On the generality of the displaywide contingent orienting hypothesis: Can a visual onset capture attention without top-down control settings for displaywide onset?

The contingent orienting hypothesis (Folk, Remington, & Johnston, 1992) states that attentional capture is contingent on top-down control settings induced by task demands. Past studies supporting this hypothesis have identified three kinds of top-down control settings: for target-specific features, for the strategy to search for a singleton, and for visual features in the target display as a whole. Previously, we have found stimulus-driven capture by onset that was not contingent on the first two kinds of settings (Yeh & Liao, 2008). The current study aims to test the third kind: the displaywide contingent orienting hypothesis (Gibson & Kelsey, 1998). Specifically, we ask whether an onset stimulus can still capture attention in the spatial cueing paradigm when attentional control settings for the displaywide onset of the target are excluded by making all letters in the target display emerge from placeholders. Results show that a preceding uninformative onset cue still captured attention to its location in a stimulus-driven fashion, whereas a color cue captured attention only when it was contingent on the setting for displaywide color. These results raise doubts as to the generality of the displaywide contingent orienting hypothesis and help delineate the boundary conditions on this hypothesis.     

Depression as a proxy of negative affect? A critical examination of the use of the CES-D in type 2 diabetes

ObjectivesRecent research suggests depression as measured by self-endorsed symptoms lists is associated with poor health outcomes in chronic illness. Yet, it is probable that these lists of symptoms reflect other concepts such as general distress or negative affect when used as dimensions.MethodsTo test for this hypothesis, we explored associations of the Centre of Epidemiological Studies-Depression, Radloff ([CES-D], 1977) with disease severity in diabetes and how trait negative affect from the Profile of Mood States ([POMS]; Usala & Hertzog, 1989; adaptation by Cohen et al., 1995) impact these associations in a sample of 502 people with type 2 diabetes.ResultsWe found that the CES-D included two dimensions of negative and positive experience. Each CES-D component was independently linked to disease severity. However, controlling for trait negative affect suppressed the correlation between the CES-D negative experience component and disease severity. Item-level analyses revealed that the negative experience component of the CES-D bore an emotional tone of sadness but not anger.ConclusionsWhen using the CES-D, distinguishing positive and negative components is necessary. Self-reported depression symptoms from the CES-D have no incremental validity over negative affect.     

Can Persistence be a Matter of Convention?

This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can, though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence” some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology of persistence—are revealed.     

Can the “Stripping of the Boss” be More Than a Joke?

In January 2011, uprisings and demonstrations broke out in Egypt, and the reverberations of the revolution are felt up to this day. The events that lead President Hosni Mubarak to resign were violent, disturbing, and definitely serious, but at the same time they were fuelled by and caused a plethora of jokes and funny slogans which circulated among the protesters. Previous studies on the functions of humour have suggested that among other things, humour can be used to enhance group cohesion by lifting up the spirits or to attack the (political) enemy by sharp sarcasm, the duality of which is captured in the metaphors of a shield and a sword. The present article builds upon “Stripping the Boss: The Powerful Role of Humor in the Egyptian Revolution 2011” by Helmy and Frerichs (2013), offering another perspective on the functionality Egyptian political jokes grounded in the current sociological approaches to humour. It aims to argue that humour as an ambiguous phenomenon is unreliable in reaching serious aims and thus cannot be conceptualised as a predictably functioning tool in conflicts, although it can sometimes give insights into the functioning of a society as a mirror of the social reality.     

Can the doctrine of just military intervention survive Iraq?

The disastrous consequences of the US-led invasion of Iraq in 2003 appear to discredit just war theories that justify military intervention in sovereign states in the name of human rights. It is possible, however, to identify factors that distinguish a defensible military intervention from the kind pursued in Iraq, and to incorporate these into a doctrine of humanitarian military intervention that would not have permitted the Iraq invasion. This improved doctrine stands in contrast to the militant interventionist doctrine that endorsed the invasion – a variant referred to here as the doctrine of just anti-totalitarian war (JAW). In order to critique the JAW doctrine and distinguish it from the improved doctrine, I examine critically the JAW-supporters' attempt to make sense of what went wrong in Iraq, and propose an alternative diagnosis. It is this alternative diagnosis that grounds a defense of moderate versions of the doctrine of just military intervention, which I seek in turn to render ‘Iraq-proof’. My Iraq-proof refinement is expressed in a list of injunctions. These require, among other things, critical interrogation of the moral standing of intervening powers and greater attention to the legitimate grievances of adversaries in regions targeted for intervention. They would also permit military intervention only in moral emergencies, and usually only to establish safe havens and protect relief supplies.     

Can the dual-route cascaded computational model of reading offer a valid account of the masked onset priming effect?

The masked onset priming effect (MOPE) refers to the empirical finding that target naming is faster when the target (SIB) is preceded by a briefly presented masked prime that starts with the same letter/phoneme (suf) than when it does not (mof; Kinoshita, 2000, Experiment 1). The dual-route cascaded (DRC) computational model of reading (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001) has offered an explanation for how the MOPE might occur in humans. However, there has been some empirical discrepancy regarding whether for nonword items the effect is limited to the first-letter/phoneme overlap between primes and targets or whether orthographic/phonological priming effects occur beyond the first letter/phoneme. Experiment 1 tested these two possibilities. The human results, which were successfully simulated by the DRC model, showed priming beyond the first letter/phoneme. Nevertheless, two recent versions of the DRC model made different predictions regarding the nature of these priming effects. Experiment 2 examined whether it is facilitatory, inhibitory, or both, in order to adjudicate between the two versions of the model. The human results showed that primes exert both facilitatory and inhibitory effects.     

How can the impact of implementation intentions as a behaviour change intervention be improved?

Interventions requesting individuals to form implementation intentions, specific plans regarding how and when to enact behaviour, have been shown to be effective in changing a wide range of health, social, and organisational behaviours. A small proportion of studies have sought to identify, within full-factorial designs, under what circumstances and for whom implementation intention-based interventions are most effective. This review covers this issue. A number of potential moderators of the effects of implementation intentions on behaviour were identified (intentions, motivation type, collaboration, plan reminders, goal type, plan type, conscientiousness, perfectionism, procrastination, stress). Of these, the strength of one's intentions have been tested, and supported, most often as a moderator of implementation intention effects. For some of these moderators (e.g., conscientiousness, goal difficulty) the results were contradictory but for others the results were more consistent (e.g., motivation type, plan reminders). Additional moderators might be identified by comparing effects of implementation intentions across studies.     

Can intelligence be estimated from drawings of a man?

There has been some disagreement as to whether intelligence can be estimated reliably and validly from the Goodenough-Harris Draw-A-Man Test (DAM). In order to assess the DAM, 21 graduate students in psychology administered the Harris DAM and either the WISC or Stanford-Binet (S-B) to 158 “normal” children. Discrepancy scores between the DAM and the S-B or WISC indicated that the DAM IQ tends to be below, at times considerably, IQs obtained from individual scales. Moreover, the DAM seemed to be virtually useless in making discriminations among children of average and superior intelligence. The Harris scoring system was not found to be more discriminating than the original Goodenough, and the results provided little encouragement for the practice of estimating intelligence from a child's DAM.     

Can there be a Uniform Application of Direct Reference?

There are two interpretations of what it means for a singular term to be referentially direct, one truth-conditional and the other cognitive. It has been argued that on the former interpretation, both proper names and indexicals refer directly, whereas on the latter only proper names are directly referential. However, these interpretations in fact apply to the same singular terms. This paper argues that, if conceived in purely normative terms, the linguistic meaning of indexicals can no longer be held to make these terms referentially indirect under the second interpretation. This result is then generalized to proper names, by ascribing them a normative meaning as well.     

Can blindness to response-compatible stimuli be observed in the absence of a response?

Blindness to response-compatible stimuli is the finding that targets are identified less accurately when presented during the planning or execution of a congruent response (e.g., right arrow presented during a right keypress) versus an incongruent response (e.g., right arrow presented during a left keypress). Accounts of this effect suggest the planning and execution of a response are critical to its observation. Five experiments investigated whether a blindness effect would be observed in the absence of a planned response. Results suggest that a planned response is not necessary to observe a content-specific blindness effect and that the blindness effect may actually comprise both an action-related component and a symbolic component that is distinct from the action-planning system.     

Can a right to health care be justified by linkage arguments?

Linkage arguments, which defend a controversial right by showing that it is indispensable or highly useful to an uncontroversial right, are sometimes used to defend the right to health care (RHC). This article evaluates such arguments when used to defend RHC. Three common errors in using linkage arguments are (1) neglecting levels of implementation, (2) expanding the scope of the supported right beyond its uncontroversial domain, and (3) giving too much credit to the supporting right for outcomes in its area. A familiar linkage argument for RHC focuses on its contributions to the right to life. Among the problems with this argument are that it requires a positive conception of the right to life that is not uncontroversial and that it only justifies the subset of RHC that seeks to prevent loss of life. A linkage argument for RHC with better prospects claims that a well-realized right to health care enhances the realization of a number of uncontroversial rights.
