Does consideration of future consequences moderate the relationship between aggression and alcohol use in adolescents? Results from the United Kingdom

Background: An increasing body of literature suggests that those who give greater consideration to the future consequences (CFC) of their present behaviours are at a reduced risk of negative health outcomes. The present study examined whether CFC moderated the relationship between four domains of aggression and alcohol use in adolescents in the United Kindgom. Methods: Participants were 1058 adolescents from Northern Ireland. Participants completed questionnaires assessing: Anger; Hostility; Verbal Aggression; Physical Aggression; Consideration of Future Consequences; and alcohol use. Results: In line with extant research males scored significantly higher than females on measures of verbal and physical aggression, with no significant gender differences observed for other dependent measures. Results also revealed that CFC moderated the relationship between aggression and alcohol use, but only for females. Conclusions: These findings add to the increasing body of literature examining the temporal-health relationship. However more work is needed to help untangle the gender-specific effects.

Selection Power and Selection Labor for Information Retrieval

This study examines the relation between selection power and selection labor for information retrieval (IR). It is the first part of the development of a labor theoretic approach to IR. Existing models for evaluation of IR systems are reviewed and the distinction of operational from experimental systems partly dissolved. The often covert, but powerful, influence from technology on practice and theory is rendered explicit. Selection power is understood as the human ability to make informed choices between objects or representations of objects and is adopted as the primary value for IR. Selection power is conceived as a property of human consciousness, which can be assisted or frustrated by system design. The concept of selection power is further elucidated, and its value supported, by an example of the discrimination enabled by index descriptions, the discovery of analogous concepts in partly independent scholarly and wider public discourses, and its embodiment in the design and use of systems. Selection power is regarded as produced by selection labor, with the nature of that labor changing with different historical conditions and concurrent information technologies. Selection labor can itself be decomposed into description and search labor. Selection labor and its decomposition into description and search labor will be treated in a subsequent article, in a further development of a labor theoretic approach to information retrieval.

Reparation or retribution: an investigation into regulatory compliance in planning

It is an axiom of good planning practice that procedure is informed by up-to-date research. Consequently, it is surprising to discover that there remains a dearth of specialised planning-enforcement literature relating to theory and implementation. In this paper an evaluation is given of the effectiveness of planning enforcement in Britain by reviewing existing legislative mechanisms and strategies employed by officials. Theoretical perspectives are drawn upon to suggest how the system might be improved through attention to the structural factors underpinning it.

Historians and their duties

We need to specify what ethical responsibility historians, as historians, owe, and to whom. We should distinguish between natural duties and (non-natural) obligations, and recognize that historians' ethical responsibility is of the latter kind. We can discover this responsibility by using the concept of “accountability”. Historical knowledge is central. Historians' central ethical responsibility is that they ought to tell the objective truth. This is not a duty shared with everybody, for the right to truth varies with the audience. Being a historian is essentially a matter of searching for historical knowledge as part of an obligation voluntarily undertaken to give truth to those who have a right to it. On a democratic understanding, people need and are entitled to an objective understanding of the historical processes in which they live. Factual knowledge and judgments of value are both required, whatever philosophical view we might have of the possibility of a principled distinction between them. Historians owe historical truth not only to the living but to the dead. Historians should judge when that is called for, but they should not distort historical facts. The rejection of postmodernism's moralism does not free historians from moral duties. Historians and moral philosophers alike are able to make dispassionate moral judgments, but those who feel untrained should be educated in moral understanding. We must ensure the moral and social responsibility of historical knowledge. As philosophers of history, we need a rational reconstruction of moral judgments in history to help with this.

Analytical calculation of far infrared spectra of ice in terms of a molecular model

Wideband far infrared (FIR) spectra of complex permittivity e(p) of ice are calculated in terms of a simple analytical theory based on the method of dipolar autocorrelation functions. The molecular model represents a revision of the model recently presented for liquid water in Adv. Chem. Phys. 127 (2003) 65. A composite two-fractional model is proposed. The model is characterised by three phenomenological potential wells corresponding to the three FIR bands observed in ice. The first fraction comprises dipoles reorienting in a rather narrow and deep hat-like well; these dipoles generate the librational band centred at the frequency approximate to 880 cm(-1). The second fraction comprises elastically interacting particles; they generate two nearby bands placed around frequency 200 cm(-1). For description of one of these bands the harmonic oscillator (HO) model is used, in which translational oscillations of two charged molecules along the H-bond are considered. The other band is produced by the H-bond stretch, which governs hindered rotation of a rigid dipole. Such a motion and its dielectric response are described in terms of a new cut parabolic (CP) model applicable for any vibration amplitude. The composite hat-HO-CP model results in a smooth epsilon(nu) ice spectrum, which does not resemble the noise-like spectra of ice met in the known literature. The proposed theory satisfactorily agrees with the experimental ice spectrum measured at - 7 degrees C. The calculated longitudinal optic-transverse optic (LO-TO) splitting occurring at approximate to 250 cm(-1) qualitatively agrees with the measured data. (c) 2004 Elsevier B.V. All rights reserved.

Dietary glycaemic index, glycaemic load and endometrial and ovarian cancer risk: a systematic review and meta-analysis.

Long-term consumption of a high glycaemic index (GI) or glycaemic load (GL) diet may lead to chronic hyperinsulinaemia, which is a potential risk factor for cancer. To date, many studies have examined the association between GI, GL and cancer risk, although results have been inconsistent, therefore our objective was to conduct a systematic review of the literature. Medline and Embase were systematically searched using terms for GI, GL and cancer to identify studies published before December 2007. Random effects meta-analyses were performed for endometrial cancer, combining maximally adjusted results that compared risk for those in the highest versus the lowest category of intake. Separate analysis examined risk by body mass index categories. Five studies examining GI and/or GL intake and endometrial cancer risk were identified. Pooled effect estimates for endometrial cancer showed an increased risk for high GL consumers (RR 1.20; 95% CI: 1.06-1.37), further elevated in obese women (RR 1.54; 95% CI: 1.18-2.03). No significant associations were observed for GI. Only two studies examined ovarian cancer and therefore no meta-analysis was performed, but results indicate positive associations for GL also. A high GL, but not a high GI, diet is positively associated with the risk of endometrial cancer, particularly among obese women. © 2008 Cancer Research UK All rights reserved.

Beckett and Performance

The recent interest in genealogical criticism in Beckett Studies, fuelled by the reading notes that Beckett compiled in the 1920’s and 1930’s, has led to a particular focus on Beckett’s formative years, and on the intersections between his work, especially the novels and early criticism, and his intellectual reading. While this has produced much valuable and fascinating matrial, perhaps it is time to return to the works themselves, and especially, to the theatre. Having just published a book on Performing Embodiment in Samuel Beckett’s Drama (London, Routledge, 2010), I would like to develop further the area of presence and performance in Beckett’s theatre. Performance studies and phenomenology have offered new ways of approaching the ontology of performance in Beckett’s theatre, and I intend to analyze this, with particular reference to specific productions of Beckett’s plays. Firstly, I want to look at some of Beckett’s own comments about particular performances / productions (for example in the Barbara Bray correspondence, Trinity College Dublin), and, secondly, to analyze from the perspective / experience of an audience member a number of performances by (mainly Anglophone) ‘Beckett actors’, including Billie Whitelaw and David Warrilow. Drawing on recent discussions of presence and performance (Jane Goodall, Cormac Power), I will offer some reflections on the complexity of presence (of persona and performer, of body and voice) and its haunting power in performances of Beckett’s drama.

Confined Site Construction: Issues Regarding Implementation of Health and Safety

The objective of this paper is to identify the various managerial constraints, difficulties and issues encountered and resulting strategies adopted, to aid in the management of the various and often complex health and safety concerns, which occur within a confined construction site. This is achieved through classifying the various managerial burdens encountered with the numerous strategies adopted, to ensure the successful management of such confined environments within the realm of health and safety. Through an extensive literature review and detailed interviews, a comprehensive insight into the health and safety concerns within a confined construction site environment is portrayed. The leading managerial strategies to the management of health and safety on confined construction sites may be listed as follows; (1) Traffic Management Plan, (2) Effective Resource Management Plan, (3) Temporary Facilities Management Plan, (4) Safe System of Work Plan, (5) Site Safety Plan, (6) Design Site Layout, (7) Space Management Plan, (8) Effective Program Management, and (9) Space Scheduling. Based on the research, it can be concluded, that through effective management of these issues identified coupled with implementing the various strategies highlighted; successful management of health and safety within a confined construction site environment is attainable.
