BackgroundAttention deficit hyperactivity disorder is clinically diagnosed; however, quantitative analysis to statistically analyze the symptom severity of children with ADHD via the measurement of head movement is still in progress. Studies focusing on the cues that may influence the attention of children with ADHD in classroom settings, where children spend a considerable amount of time, are relatively scarce. Virtual reality allows real-life simulation of classroom environments and thus provides an opportunity to test a range of theories in a naturalistic and (...) controlled manner. The objective of this study was to investigate the correlation between participants’ head movements and their reports of inattention and hyperactivity, and to investigate how their head movements are affected by different social cues of different sensory modalities.MethodsThirty-seven children and adolescents with and without ADHD were recruited for this study. All participants were assessed for diagnoses, clinical symptoms, and self-reported symptoms. A virtual reality-continuous performance test was conducted under four conditions: control, no-cue, visual cue, and visual/audio cue. A quantitativecomparison of the participants’ head movements was conducted in three dimensions using a head-mounted display in a VR classroom environment. Task-irrelevant head movements were analyzed separately, considering the dimension of movement needed to perform the VR-CPT.ResultsThe magnitude of head movement, especially task-irrelevant head movement, significantly correlated with the current standard of clinical assessment in the ADHD group. Regarding the four conditions, head movement showed changes according to the complexity of social cues in both the ADHD and healthy control groups.ConclusionChildren and adolescents with ADHD showed decreasing task-irrelevant movements in the presence of social stimuli toward the intended orientation. As a proof-of-concept study, this study preliminarily identifies the potential of VR as a tool to understand and investigate the classroom behavior of children with ADHD in a controlled, systematic manner.

Quantitative assessments of when infectious disease outbreaks end are crucial, as resources targeted towards outbreak responses typically remain in place until outbreaks are declared over. Recent improvements and innovations in mathematical approaches for determining when outbreaks end provide public health authorities with more confidence when making end-of-outbreak declarations. Although quantitative analyses of outbreaks have a long history, more complex mathematical and statistical methodologies for analysing outbreak data were developed early in the 20th century and continue to be refined. Historically, such (...) methodologies focused primarily on factors affecting the early and middle phases of an outbreak, with less attention given to determining how and when outbreaks end. This review discusses mathematical modelling methods from the last 20 years that have been developed for determining the ends of infectious disease outbreaks, and considers factors that affect the accuracy of such determinations. When disease surveillance systems provide timely and representative data to inform models, the timings of end-of-outbreak declarations can be fine-tuned to allow outbreaks to be declared over quickly and with a low risk of being incorrect. Premature declarations that outbreaks are over can undermine earlier achievements in disease control and may result in a resurgence of cases, but unnecessary delays in declaring outbreaks over can cause significant economic and social harm. Appropriate declarations that balance the benefits of relaxing control measures against the risk of a surge in cases allow public health resources to be conserved (and economic and social pressures to be reduced) while limiting the potential for additional transmission.

Zhi 李贄, also named ( hao 號) Zhuowu 卓吾 (1527–1602), and argues that he articulates a coherent and compelling vision of a good life focused on the expression of genuine feelings distinctive to each individual. Through a study of literary texts and terms of art he refers to in his critical essay “On the Child-like Heart-mind” ( Tongxin Shuo 童心說), as well as the metaphors and images he fleshes out throughout his writings, I characterize Li’s ethical vision and show that (...) it is rooted in a particular loose and accommodating conception of human nature and centered on the simple and intuitive act of daily maintaining the birthright of our “child-like heart-mind.”.

In this paper, we investigate a new model theoretical tree property (TP), called the antichain tree property (ATP). We develop combinatorial techniques for ATP. First, we show that ATP is always witnessed by a formula in a single free variable, and for formulas, not having ATP is closed under disjunction. Second, we show the equivalence of ATP and [Formula: see text]-ATP, and provide a criterion for theories to have not ATP (being NATP). Using these combinatorial observations, we find algebraic examples (...) of ATP and NATP, including pure groups, pure fields and valued fields. More precisely, we prove Mekler’s construction for groups, Chatzidakis’ style criterion for pseudo-algebraically closed (PAC) fields, and the AKE-style principle for valued fields preserving NATP. We give a construction of an antichain tree in the Skolem arithmetic and atomless Boolean algebras. (shrink)

The effect of uniform lighting on face identity processing is little understood, despite its potential influence on our ability to recognize faces. Here, we investigated how changes in uniform lighting level affected face identification performance during face memory tests. Observers were tasked with learning a series of faces, followed by a memory test where observers judged whether the faces presented were studied before or novel. Face stimuli were presented under uniform bright or dim illuminations, and lighting across the face learning (...) and the memory test sessions could be the same or different. This led to four experimental conditions: Bright/Dim ; Bright/Bright; Dim/Bright; and Dim/Dim. Our results revealed that incongruent lighting levels across sessions significantly reduced sensitivity to faces and introduced conservative biases compared to congruent lighting levels. No significant differences in performance were detected between the congruent lighting conditions and between the incongruent lighting conditions. Thus, incongruent lighting deteriorated performance in face identification. These findings implied that the level of uniform lighting should be considered in an illumination-specific face representation and potential applications such as eyewitness testimony. (shrink)

Aggleton & Brown rightly point out the shortcomings of the medial temporal lobe hypothesis as an approach to anterograde amnesia. Their broader perspective is a necessary corrective, and one hopes it will be taken very seriously. Although they correctly note the dangers of conflating recognition and recall, they themselves make a similar mistake in discussing familiarity; we suggest an alternative approach. We also discuss implications of their view for an analysis of retrograde amnesia. The notion that there are two routes (...) by which the hippocampus can reactivate neuronal ensembles in the neocortex could help us understand some currently puzzling facts about the dynamics of memory consolidation.

Diffusion models are widely-used and successful accounts of the time course of two-choice decision making. Most diffusion models assume constant boundaries, which are the threshold levels of evidence that must be sampled from a stimulus to reach a decision. We summarize theoretical results from statistics that relate distributions of decisions and response times to diffusion models with time-varying boundaries. We then develop a computational method for finding time-varying boundaries from empirical data, and apply our new method to two problems. The (...) first problem involves finding the time-varying boundaries that make diffusion models equivalent to the alternative sequential sampling class of accumulator models. The second problem involves finding the time-varying boundaries, at the individual level, that best fit empirical data for perceptual stimuli that provide equal evidence for both decision alternatives. We discuss the theoretical and modeling implications of using time-varying boundaries in diffusion models, as well as the limitations and potential of our approach to their inference. (shrink)

Most modern evangelicals classify the Abrahamic covenant as unconditional. But the label is ambiguous. A review of the covenant passages strongly suggests that the blessings promised to Abraham were conditioned on his obedience – making the covenant, in this sense, conditional. On the other hand, once Abraham obeyed God’s commands, the covenant became prophetically guaranteed – and is, in this sense, unconditional.The nuance is more than theological trivia, for God’s dealings with Abraham have profound implications for us. Abraham received imputed (...) righteousness by faith, without conditions of obedience. But his justification did not guarantee him historic/prophetic prominence. That flowed from his submission to Yahweh. I suggest that these twin principles are universal, applying to believers of every age.All scripture quotations are from the New American Standard Bible unless otherwise indicated.

continent. 1.4 (2011): 310—311. Writing Death . Jeremy Fernando, foreword by Avital Ronell. Den Haag: Uitgeverij. 2011 ISBN: 978-90-817091-0-1 Rite and ceremony as well as legend bound the living and the dead in a common partnership. They were esthetic but they were more than esthetic. The rites of mourning expressed more than grief; the war and harvest dance were more than a gathering of energy for tasks to be performed; magic was more than a way of commanding forces of nature (...) to do the bidding of man; feasts were more than a satisfaction of hunger. Each of these communal modes of activity united the practical, the social, and the educative in an integrated whole having esthetic form.(1) Jeremy Fernando’s Writing Death is a sensitive attempt at exploring the depths and heights to which the processes of mourning can take us. Death, as an absence, renders all gestures (for what is mourning but a gesture with many faces) surrounding it at once as a possibility and an impossibility. Fernando poses questions that often elude the mourner and the mourned—the same, and different—by raising the specter of subject and object; by compelling the examination of what it actually means to mourn; and most crucially, by considering the very status of possibility itself that the act of mourning foregrounds. Mourning, he reminds us, is premised upon memory (remembrance, recollection), the shadow of forgetting upon which is perpetually cast—the inextricability between memory and forgetting haunts the living more than it does the dead. And if grief has anything to do with it, mourning can quite easily be mistaken for an attempt to remember in order to forget; an attempt, in other words, to deny death, deny the one thing that confirms mortality. As if living has anything to do with it. What, then, of writing death? It becomes an unceasing process of locating—and addressing—possibility itself: the passing as possibility; loss as possibility; impossibility as, and of, naming this possibility. In confronting the passing on, it is possible, nay inevitable, to move on, move away from the site of loss, of grief. All the while, we forget, Fernando reminds us, that mourning has little to do with the dead, and a whole lot to do with the living, the mourning self. Here, he echoes Dewey’s consolidation of rituals and ceremonies, of the dead and of the living, all as parts of a larger unity, of a social, public gesture meant to sate a private need: In trying to “get over it,” are we trying to get over ourselves? Or more than that: are we trying to get over the fact that we can never quite get over ourselves? (Fernando, 77) As if guilt has anything to do with it. And “it” continues to be the point that he is driving at, driving towards. “It” is the possibility and impossibility, death and life, memory and forgetting, lost and cherished. “It” is what eludes mourning, eludes attempts to overcome grief. Nonetheless, move on, he must. And Fernando does this in fewer moves than a 12-step program—hardly therapeutic, but intellectually satisfying. Writing Death attends to some of the pertinent aspects of the act of mourning—both as gesture and as meditation: eulogy, distress (call), tears, and the question of how (beyond ritual, beyond sentimentality) to mourn. And what’s love got to do with it? Everything and nothing. Mourning, after all, is an articulation of love, but it is also one that forces the mourner to be selective, as with myth-making, in the recollection: Remembering only ever occurs in exception to memory—quite possibly in betrayal of a memory. In this way, each remembrance is a naming of that memory, a naming of something as memory, bringing with it an act of violence. (40) Mourning is thus not only an act of fictionalizing, it is also an act of reading, to continually be compelled to respond to another, all the while keeping vigil against a reconceptualization of the dead, without, therefore, misreading the dead. This can only be done, Fernando argues, by all the while “maintaining the otherness of the other. After all, one must try not to forget that one cannot be too close—space is needed—to touch.” (82) There is also tacit acknowledgement that doing so foregrounds the fact that the selectivity of memory becomes exclusive, and concretizes into a singularity, thus negating the multi-dimensionality of a life lived – and thus killing the already dead. Writing Death is framed by two eulogies—or the approximations of eulogies; approximation because both foreground and call into question the eulogy as a genre. The first is Avital Ronell’s foreword to the book, remembering Philippe Lacoue-Labarthe; the second is Fernando’s own response to the passing of a mentor, Jean Baudrillard. Both are not merely attempts to philosophize their way out of the act of mourning. Both are in fact deeply moving pieces that remind us of the emotional possibilities that may reside within any intellectual undertaking, that the latter need not be cold and devoid of feelings. And whereas Writing Death does not attempt to make any philosophical claim for humanism, the underlying wistfulness of both pieces does suggest that there is a proper place for deep-seated human response to death. We can (and the book does) intellectualize and problematize the acts of mourning and grieving, but these do not diminish the fact that we mourn and grieve. And, framing Writing Death as the two eulogies do, Jeremy Fernando perhaps finally, and inadvertently, names “It”—it is, above everything else, Human. August, 2011 Singapore NOTES (1) Dewey, John.

The second edition of H. P. Lee's The Australian Judiciary provides a timely update to this seminal text. The only definitive survey of the entire Australian judiciary, this text describes and evaluates the work, techniques, problems and the future of the different tiers of courts and judges. It discusses the role of the judiciary as the third sector of government and analyses and comments on judicial conduct, judicial independence and impartiality, the work of judges beyond the courts, the accountability of (...) judges and the dangers to judicial institutions. It is an excellent reference work which will appeal to legal scholars and practitioners throughout Australia and internationally. (shrink)

Many studies examine student self-concept during compulsory schooling but few have explored the self-concept of students in higher educational settings. The current study examined self-concept by faculty and gender among higher education students in New Zealand. Participants were 929 undergraduate students from a large New Zealand university. The results showed some differences in verbal and maths self-concept by faculty. Generally, students in faculties teaching subjects more reliant on maths skills had higher maths self-concept than those in faculties where facility in (...) verbal skills was important. The opposite results were found for verbal self-concept. No overall gender differences were found for general, academic, verbal and maths self-concept although a statistically significant difference was found for problem-solving self-concept. This finding suggests students? choice of faculty may be based on perceptions of their skills and capabilities in the various fields, irrespective of gender. (shrink)

While self-report data is a staple of modern psychological studies, they rely on participants accurately self-reporting. Two constructs that impede accurate results are insufficient effort responding and response styles. These constructs share conceptual underpinnings and both utilized to reduce cognitive effort when responding to self-report scales. Little research has extensively explored the relationship of the two constructs. The current study explored the relationship of the two constructs across even-point and odd-point scales, as well as before and after data cleaning procedures. (...) We utilized IRTrees, a statistical method for modeling response styles, to examine the relationship between IER and response styles. To capture the wide range of IER metrics available, we employed several forms of IER assessment in our analyses and generated IER factors based on the type of IER being detected. Our results indicated an overall modest relationship between IER and response styles, which varied depending on the type of IER metric being considered or type of scale being evaluated. As expected, data cleaning also changed the relationships of some of the variables. We posit the difference between the constructs may be the degree of cognitive effort participants are willing to expend. Future research and applications are discussed. (shrink)
