Childhood predictors of adult criminality: are all risk factors reflected in childhood aggressiveness?

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 3 2002
L. Rowell Huesmann
Background Early aggressive behaviour is one of the best predictors of adult criminality. Aim To assess the degree to which family background variables, parental beliefs and behaviour and child intelligence predict child aggression and adult criminality. Method Data were used from the Colombia County Longitudinal Study, a longitudinal study of 856 children in third grade in New York, in 1959,60. Adult measures of criminal behaviour, child measures taken at age eight, child peer-nominated aggression, child's peer-nominated popularity, child's IQ and parental measures at eight years were used. Results Aggressive children were less intelligent, less popular, rejected more by their parents, had parents who believed in punishment, were less identified with their parents' self-image and were less likely to express guilt. As adults, more aggressive children with parents who were less well educated, experienced more marital disharmony and who seldom attended church were most at risk for arrest. However, after the effect of early aggression was controlled, most effects disappeared and only parents having a strong belief in punishment added significantly to risk of arrest by age 30; the only fact that then reduced the risk of arrest was having parents who attended church often. Both parental authoritarianism and child IQ reduced the risk of conviction for arrested children. Discussion Level of aggression at age eight is the best predictor of criminal events over the next 22 years. A clear implication is that the risk for criminality is affected by much that happens to a boy before he is eight years old. Preventive interventions need to target risk factors that appear to influence the development of early aggression. Copyright © 2002 Whurr Publishers Ltd. [source]


The role of competence level in the self-efficacy,skills relationship: an empirical examination of the skill acquisition process and its implications for information technology training

INTERNATIONAL JOURNAL OF TRAINING AND DEVELOPMENT, Issue 2 2009
James P. Downey
The role of computer training has long been critical in organizations as reliance on technology for strategic advantage increases in importance. How to most effectively conduct such training has clear implications for organizations. This study examines one area of training which is not well understood: the role that competence level plays in the self-efficacy,competence relationship (if indeed it plays a role at all) during skill acquisition. Two opposing conceptual positions are presented from the literature, one that suggests the relationship between self-efficacy and competence will be stronger early in the skill acquisition process (when competence is minimal), the other suggesting the strength of the relationship will be stronger at mastery. Using a sample of over 600 and structural equation modeling, the relationship between self-efficacy and competence for six different computing application domains is tested by dividing respondents in each domain in half, according to competence level. Results empirically demonstrate that level of competence makes a significant difference in the domains, that those higher in ability typically have a stronger relationship with self-efficacy. Results also show that the relationship is weaker for those new to the application and those who have mastered the application. The important implications for training are discussed. [source]


Assessing the dietetic needs of different patient groups receiving enteral tube feeding in primary care

JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 3 2002
S. M. Madigan
Abstract Aim To examine the nature of all contacts between adult tube-fed patients and the dietetic service and to refine the current dietetic protocols to reflect the findings of the study with a view to improving patient care. Methods All adult patients referred to the Community Nutrition and Dietetic Service within a 6-month period were included in the study. Using a proforma developed from a retrospective case-note analysis, data were collected on the complications that prompted more frequent contacts than the department protocol. Data were analysed using the Statistical Package for the Social Sciences. Results The most common indication for home enteral feeding in this group of adult patients was a swallowing disorder resulting from a cerebrovascular accident (59.5%) followed by cancer (21.5%). There was a trend for cancer patients to need more intervention compared with those patients with other medical conditions. A significant difference was observed in the total contacts and telephone calls given to those patients in there own homes (P=0.019) and there was a trend towards more domicilary visits with this group. Conclusions The department protocols have been revised to include a planned review within 2,6 weeks of initial dietetic assessment in the community for those patients who were identified to have the greatest need. More intensive dietetic monitoring has clear implications for dietetic services in the community. [source]


Structural characteristics of university engineering students' conceptions of energy,

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 5 2002
Xiufeng Liu
This study examined structural characteristics of university engineering students' conceptions of energy elicited through paragraph writing and their relations with categories of their conceptions specific to energy in solution processes identified through interviews. We found that structures of students' conceptions are characterized primarily by characteristic, example-of/type-of, and lead-to types of relations, and these relations correspond with categories of students' conceptions. More specifically, categories of students' conceptions are exclusively related to energy transformation, and students failed to apply the notion of energy conservation demonstrated in structures of their conceptions to explain the temperature change in solution processes. It is concluded that although paragraph writing and interviews solicit different student conceptions, the conceptions identified from the two sources are related and paragraph writing tends to provide a more holistic picture of students' conceptions. This conclusion has clear implications for science curriculum development and instruction. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 423,441, 2002 [source]


Literacy as a complex activity: deconstructing the simple view of reading

LITERACY, Issue 2 2008
Morag Stuart
Abstract The Rose Review into the teaching of early reading recommended that the conceptual framework incorporated into the National Literacy Strategy Framework for Teaching , the Searchlights model of reading and its development , should be replaced by the Simple View of Reading. In this paper, we demonstrate how these two frameworks relate to each other, and show that nothing has been lost in this transformation from Searchlights to Simple View: on the contrary, much has been gained. That nothing has been lost is demonstrated by consideration of the underlying complexity inherent in each of the two dimensions delineated in the Simple View. That much has been gained is demonstrated by the increased understanding of each dimension that follows from careful scientific investigation of each. The better we understand what is involved in each dimension, the better placed we are to unravel and understand the essential, complex and continual interactions between each dimension which underlie skilled reading. This has clear implications for further improving the early teaching of reading. [source]


Patient priorities of care in rheumatology outpatient clinics: a qualitative study

MUSCULOSKELETAL CARE, Issue 4 2007
Vicky Ward PhD
Abstract Objective:,To provide more understanding of what rheumatoid arthritis (RA) patients want and need from an outpatient visit. Methods:,25 patients who experienced care in a nurse practitioner clinic (n = 10), junior doctor clinic (n = 9) or consultant clinic (n = 6) in a large teaching hospital in West Yorkshire were interviewed about their perceptions and experiences of care. Interviews were approximately 11/2 hours in duration and were carried out in a neutral environment by a research nurse. Interview data were subjected to atheoretical content analysis, which resulted in the identification of emergent themes. Results:,Five main themes emerged from the analysis of interview data: 1) patients want to be communicated to clearly and effectively and value positive relationships with practitioners. These help to give patients confidence in the care they are receiving; 2) patients want to feel in control of their condition and tend to refuse interventions as a way of gaining control; 3) patients want to be given clear explanations during consultations, and want information in oral and written forms; 4) patients want to be able to access practitioners between scheduled appointments as a way of gaining reassurance; and 5) patients want to feel valued by society through having their difficulties appreciated and understood by others. Conclusion:,This research adds to the body of evidence on what patients want from their rheumatology care, and each theme has clear implications for future practice.

Tropical-cyclone intensification and predictability in three dimensions

THE QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY, Issue 632 2008
Nguyen Van Sang
Abstract We present numerical-model experiments to investigate the dynamics of tropical-cyclone amplification and its predictability in three dimensions. For the prototype amplification problem beginning with a weak-tropical-storm-strength vortex, the emergent flow becomes highly asymmetric and dominated by deep convective vortex structures, even though the problem as posed is essentially axisymmetric. The asymmetries that develop are highly sensitive to the boundary-layer moisture distribution. When a small random moisture perturbation is added in the boundary layer at the initial time, the pattern of evolution of the flow asymmetries is changed dramatically, and a non-negligible spread in the local and azimuthally-averaged intensity results. We conclude, first, that the flow on the convective scales exhibits a degree of randomness, and only those asymmetric features that survive in an ensemble average of many realizations can be regarded as robust; and secondly, that there is an intrinsic uncertainty in the prediction of maximum intensity using either maximum-wind or minimum-surface-pressure metrics. There are clear implications for the possibility of deterministic forecasts of the mesoscale structure of tropical cyclones, which may have a major impact on the intensity and on rapid intensity changes. Some other aspects of vortex structure are addressed also, including vortex-size parameters, and sensitivity to the inclusion of different physical processes or higher spatial resolution. We investigate also the analogous problem on a ,-plane, a prototype problem for tropical-cyclone motion. A new perspective on the putative role of the wind--evaporation feedback process for tropical-cyclone intensification is offered also. The results provide new insight into the fluid dynamics of the intensification process in three dimensions, and at the same time suggest limitations of deterministic prediction for the mesoscale structure. Larger-scale characteristics, such as the radius of gale-force winds and ,-gyres, are found to be less variable than their mesoscale counterparts.

ASSESSING THE PERFORMANCE OF THE PUBLIC SECTOR

ANNALS OF PUBLIC AND COOPERATIVE ECONOMICS, Issue 1 2009
Pierre Pestieau
ABSTRACT,:,One is used to hearing harsh statements about inefficient public services. It is not surprising to see public sector performance questioned. What is surprising is that what is meant by performance, and how it is measured, does not seem to matter much to either the critics or the advocates of the public sector. The purpose of this paper is to suggest a definition, and a way to measure the performance of the public sector or rather of its main components. Our approach is explicitly rooted in the principles of welfare and production economics. We will proceed in four stages. First of all we present what we call the ,performance approach' to the public sector. This concept rests on the principal-agent relation that links a principal, i.e., the State, and an agent, i.e., the person in charge of the public sector unit, and on the definition of performance as the extent to which the agent fulfils the objectives assigned by the principal. The performance is then measured by using the notion of productive efficiency and the ,best practice' frontier technique. In the second stage we move to the issue of measuring the performance of some canonical components of the public sector (education, health care and railways transport), assuming that there is no constraint as to data availability. The idea is to disentangle the usual confusion between conceptual and data problems. In the third stage, we move to real world data problems. The question is then given the available data, whether it makes sense to assess and measure the performance of such public sector activities. The final stage is devoted to explaining performance or rather lack thereof. This exercise has clear implications for public policy. Finally we argue that when the scope is not components but the entirety of the public sector, one should restrict the performance analysis to outcomes and not relate them to inputs. [source]


What a difference a year makes: How immediate and anniversary media reports influence judgements about earthquakes

ASIAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 3 2002
Jodie Cowan
Research suggests that the content of newspaper and television reports about natural disasters, such as earthquakes, affects people's fatalistic judgements about these disasters. The present paper contains two studies, Study 1 and Study 2. Study 1 examined features in newspaper reports written at two time points following two major earthquakes: immediately after the earthquakes and a year following the earthquakes. These reports showed several features about the earthquakes: in reports immediately after the earthquakes, the reports were concerned about earthquake agency and general damage; and in reports written a year following the earthquakes, the reports portrayed specific damage and lessons. Study 2 examined the influence of these features on students' (n = 160) estimates of the extent of damage, attributions for damage and judgements of the preventability of the damage. With excerpts presenting specific damage and lessons, participants gave lower estimates of damage, judged damage to be more preventable and attributed the damage more to building design than with earthquake agency and general damage descriptions of the same earthquakes. These findings have clear implications for the way the media and civic education programs present information on earthquakes and other disasters. [source]


Phylogenetic relationships of the spider family Tetragnathidae (Araneae, Araneoidea) based on morphological and DNA sequence data

CLADISTICS, Issue 2 2009
Fernando Álvarez-Padilla
The monophyly of Tetragnathidae including the species composition of the family (e.g., Are Nephila and their relatives part of this lineage?), the phylogenetic relationships of its various lineages, and the exact placement of Tetragnathidae within Araneoidea have been three recalcitrant problems in spider systematics. Most studies on tetragnathid phylogeny have focused on morphological and behavioral data, but little molecular work has been published to date. To address these issues we combine previous morphological and behavioral data with novel molecular data including nuclear ribosomal RNA genes 18S and 28S, mitochondrial ribosomal RNA genes 12S and 16S and protein-coding genes from the mitochondrion [cytochrome c oxidase subunit I (COI)] and from the nucleus (histone H3), totaling ca. 6.3 kb of sequence data per taxon. These data were analyzed using direct optimization and static homology using both parsimony and Bayesian methods. Our results indicate monophyly of Tetragnathidae, Tetragnathinae, Leucauginae, the "Nanometa clade" and the subfamily Metainae, which, with the exception of the later subfamily, received high nodal support. Morphological synapomorphies that support these clades are also discussed. The position of tetragnathids with respect to the rest of the araneoid spiders remains largely unresolved but tetragnathids and nephilids were never recovered as sister taxa. The combined dataset suggests that Nephilidae is sister to Araneidae; furthermore, the sister group of Nephila is the clade composed by Herennia plus Nephilengys and this pattern has clear implications for understanding the comparative biology of the group. Tetragnathidae is most likely sister to some members of the "reduced piriform clade" and nephilids constitute the most-basal lineage of araneids. [source]
