Feather pecking in domestic chicks: its relation to dustbathing and foraging

Feather pecking is a serious problem in poultry housing, as it may lead to feather damage, injuries and even mortality. We tested predictions of the two prevalent hypotheses claiming that feather pecking is related to dustbathing and foraging, respectively. Forty-two groups of 30 laying hen chicks, Gallus gallus domesticuswere reared in pens with a slatted floor. Access to sand as a dustbathing substrate and straw as a foraging substrate was varied between groups. The rate of feather pecking was measured in early development up to week 7. The provision of a sand area did not prevent the chicks from developing high rates of feather pecking that caused injuries. Chicks that had access to sand from day 10 showed higher rates of feather pecking than chicks that had access to sand from day 1. The provision of straw to chicks that had developed high rates of feather pecking led to a decrease in this behaviour. Chicks that could use both sand and straw from day 1 on did not show high rates of feather pecking, and no injuries were observed in these groups. There was no significant difference in dustbathing activity between housing conditions characterized by high or low rates of feather pecking. On the other hand, foraging activity was inversely related to the rate of feather pecking, and the occurrence of feather pecking could be delayed from week 4 to week 7 by postponing procedures that led to changes in foraging behaviour. In conclusion, the results show that the presence of an appropriate substrate for dustbathing does not prevent domestic chicks from developing feather pecking. On the other hand, housing conditions that promote foraging behaviour are effective in reducing and preventing feather pecking.Copyright 1997 The Association for the Study of Animal Behaviour1997The Association for the Study of Animal Behaviour

Attitudes to cardiovascular health promotion among GPs and practice nurses.

BACKGROUND: Cardiovascular health promotion is an important element of national health strategy, but doubts have been raised about current methods, and attitudes among general practice staff are ambivalent. OBJECTIVES: We aimed to assess attitudes to cardiovascular health promotion, opinions about efficacy and perceptions of skills in lifestyle counselling in GPs and nurses from the same practices. METHOD: A questionnaire survey of 107 GPs and 58 practice nurses from 19 group practices (100% response rate). RESULTS: Practice nurses were seen to have the main responsibility for cardiovascular health promotion. Although attitudes to health promotion were generally positive, lack of training in lifestyle counselling was perceived to be a problem. Few responders believed that they were very influential in helping people change their lifestyles. Beliefs about the effectiveness of lifestyle counselling were mixed, with cigarette smoking, physical inactivity and obesity being seen as difficult to change. Beliefs in the effectiveness of lifestyle counselling were associated with positive attitudes towards health promotion and greater confidence in training. No association between personal health behaviour and attitudes towards health promotion were observed. CONCLUSIONS: It is recognized that health promotion involves more than the provision of simple information and advice, but GPs and practice nurses lack confidence in lifestyle counselling skills. The attitudes of health professionals are crucial to the implementation of prevention strategies and require regular review.

Subordinate superb fairy-wrens (Malurus cyaneus) parasitize the reproductive success of attractive dominant males.

Explanations of cooperative breeding have largely focused on the indirect benefits philopatric offspring gain from investing in kin. However, recent molecular studies have revealed that in many species subordinates provision unrelated offspring. This has led to the re-evaluation of the direct and indirect benefits of helping behaviour. In this study, we used microsatellite genotyping to assess the extra-group reproductive success of subordinate superb fairy-wrens (Malurus cyaneus), a species with extremely high rates of extra-group paternity. Extra-group subordinate males sired 10.2% (193 out of 1895) of all offspring sampled between 1993 and 2000 and 21.4% (193 out of 901) of all illegitimate offspring sired by known males. The extra-group success of subordinates was greatly influenced by the attractiveness of their dominant male. Subordinates of attractive dominants sired more extra-group young than did average dominants. Evidence suggests that mate choice in superb fairy-wrens is error-prone and subordinates can gain direct reproductive benefits through parasitizing the reproductive success of attractive dominants.

Community adjustment of mobile people with learning difficulties after total hospital closure: a preliminary report.

A study is described in which 50 residents of a hospital for people with learning difficulties were assessed immediately before and 1 year after moving into two types of community provision; purpose-built campuses or small homes in residential streets. Measures were taken of residents' adaptive and unwanted behaviours and of aspects of their lifestyles. The results report the changes in these measures that were found for both campus and small home residents.

Empirical data for the purpose of multidimensional analysis of alcohol delinquency-related behaviour.

With the aim of determining the differences, if any, between voluntarily admitted alcohol-dependent patients and those treated in a forensic hospital with regard to criminal behaviour caused by alcohol, a study was conducted within a clinical section to analyse 41 patients confined under the provisions of the German Penal Code (StGB, section 64) and 55 patients who were admitted voluntarily. There is virtually no difference in the patterns of delinquency of the two groups; plain theft, fraud, defalcation and damage of property are predominant. This however, does not apply to acts of killing, which were exclusively found in patients who were treated in a forensic hospital, the frequency of delinquency being predominant in the latter group. According to anamnesis, a comprehensive list of questions containing more than 400 items as well as a series of test-psychological investigations, a psychic profile is elaborated by means of significant data or showing a tendency towards significance. In accordance with the result of operationalised diagnostics, only 51.2 per cent of the patients of confinement showed a primary alcohol dependence. As far as the other patients of the group (who had been wrongly confined within the meaning of the law) were concerned, the predominant diagnosis was a disturbed personality with accompanying alcohol abuse, whereas in the group of voluntarily admitted patients the proportion of primary alcohol dependence was 81.8 per cent.

Receipt of psychotropic medication by people with intellectual disability in residential settings.

Previous studies have reported that the rate of prescription of antipsychotic medication for people with intellectual disability is far in excess of the expected prevalence of psychoses for this population. Recent research identifying factors which predict the use of psychotropic medication suggests that challenging behaviour may play a key role in determining the receipt of antipsychotic medication. The present study reports the prevalence of psychoactive medication receipt for 500 people with intellectual disability living in different forms of residential provision in the UK. Variables which predict the receipt of psychotropic medication are also identified. The results show differences between forms of residential provision in rates of medication receipt. Analyses of predictors of psychotropic medication receipt suggest that, whilst the receipt of antidepressants is predicted by symptoms of mental ill health, the receipt of both antipsychotics and hypnotics/anxiolytics is predicted by variables related to challenging behaviour.

Provision of services for mentally handicapped children in the Witwatersrand area.

Childhood mental retardation is defined as significantly subaverage general intellectual functioning existing together with difficulty in adaptive behaviour, manifesting during the period from birth to 18 years. We addressed the issues of diagnosis, placement and management of the mentally handicapped child in the Witwatersrand area and surveyed facilities available for them. According to our calculations, facilities were adequate for 69.7% white, 26% Indian, 9.3% coloured and only 7.6% black children. Urgent attention must be given to providing more care for these children, especially those with profound mental retardation. A special class in a regular school is the most appropriate environment for the mildly to moderately retarded group.

Condom-promotion programme among slum-dwellers in Chandigarh, India.

This study describes high-risk behaviour and condom usage in inhabitants of an urban slum in the Union Territory of Chandigarh, which has a population of about 20,000. A cohort of 375 participants was followed-up before and after an intervention. Half of the married but only one-eighth of the unmarried slum dwellers were using condoms regularly. One-quarter of the study subjects practised high-risk behaviour and this was higher among unmarried (44.88%) than married participants (18.7%). An intervention involving education on condom use and provision of free condoms increased the condom usage rate from 31.73% in the pre-intervention phase to 60% in the postintervention phase.

What is action research and can it promote change in primary care?

Improving the quality of health care is an international priority. However, research has shown that methods of altering clinician's behaviour or implementing organizational change are often ineffective. Action research has been used successfully to facilitate change and improve service provision in industry, education and more recently in health care. In this paper, action research methodology and why it should be successful in promoting change are outlined. Recently published studies using action research in the primary health care team setting in the UK are discussed. They demonstrate that action research improves clinical care, teamwork, communication and administration. It also encourages practice teams to audit their work and identify their educational needs. The main problems encountered were the amount of time and effort required to maintain collaboration with participants, staff turnover and completing the research process in a short time scale. Action research should be a useful means of improving quality in health care and could be used more widely. In the UK, government strategy has called for individual- and team-based development plans based on individual learning needs. Action research could be a useful method of transforming these from theory to practice.

Confidentiality in psychological practice: a decrepit concept?

Although the principle of confidentiality in the relationship between psychologists and client has been vaunted, and is emphasised in the Australian Psychological Society's Code of Professional Conduct (the APS code; 1994), the confidentiality of this relationship is circumscribed by the absence of legal protections, the ethical beliefs of psychologists, institutional practices, and the provisions of the APS code itself. Lack of privilege in judicial proceedings, and statutory obligations to report certain types of behaviour, mandate breaches of confidentiality in some circumstances. Ethical beliefs of psychologists may support disclosure, especially where it is believed that there is danger of serious physical harm to the client or others. Multidisciplinary teams and institutional settings require the exchange of information for optimal delivery of services. Recent amendments to the APS code may require disclosure without the client's consent when a client is believed to be suicidal. Such developments, when considered at all, are typically regarded as exceptions to a general obligation of confidentiality. However, discussion of exceptions presupposes agreement on fundamental principle: the significance of, and rationale for, confidentiality in the psychologist-client relationship. It is argued in this paper that the obligation of confidentiality has been assumed rather than vigorously analysed and empirically explored. A critical examination of this obligation is the most appropriate starting point for the rehabilitation of contemporary principles of confidentiality in the psychologist-client relationship.

Pain- and distress-reducing interventions for venepuncture in children.

OBJECTIVE: To compare the effect of eutectic mixture of local anaesthetics (EMLA) and a placebo cream on reported pain and observed distress associated with venepuncture, and to investigate effects of procedural information before and distraction during venepuncture. METHODS: Children 3-12 years of age undergoing venepuncture under five experimental and a control condition reported their pain at venepuncture on visual scales. Distress was observed when the child entered the waiting room, just before, and during venepuncture. RESULTS: Distress increased over the measurement occasions, but a distress-reducing effect of EMLA only was found at the actual venepuncture. The placebo diminished the reported pain, but the effect of EMLA was larger. Procedural information and distraction showed no effects. CONCLUSIONS: EMLA reduces pain from venepuncture. The placebo effect probably results from desirable responding. Behavioural distress is a more direct measure than self-reported pain. More sophisticated designs should be used for the provision of procedural information and distraction.

Collaboration of a dentist and speech-language pathologist in the rehabilitation of a stroke patient with dysarthria: a case study.

OBJECTIVE: To elucidate the effectiveness of the collaboration of a dentist and speech-language pathologist (SLP) in the rehabilitation of a stroke patient with dysarthria. DESIGN: A clinical case report treated in the rehabilitation hospital and dental surgery. SUBJECT: A 71-year-old Japanese man who was admitted to the rehabilitation hospital for speech rehabilitation 2 years and 5 months after a stroke. METHODS: Provision of prosthesis (palatal lift prosthesis + palatal augmentation prosthesis) for improving velopharyngeal incompetence (VPI) and articulation by dentist, and speech behavioural management by SLP including self-monitoring and bio-feedback training using the See-Scape. RESULTS: Speech behavioural management proved useful for promoting improvement in speech intelligibility to a functionally sufficient level after improving VPI by prosthesis. CONCLUSION: The collaborative efforts of the dentist and SLP in the rehabilitation of post-stroke patients with velopharyngeal incompetence should be encouraged.

Need and demand for parenting programmes in general practice.

AIMS: To establish the prevalence of behaviour problems and the level of interest in parenting programmes in a population sample of parents of children aged 2-8 years, and to assess to what extent they are associated with socioeconomic factors. METHODS: Postal survey of parents of children aged 2-8 years registered with three general practitioner surgeries; 70% response rate. RESULTS: One fifth of parents from this population sample were experiencing difficulties with their children's behaviour. While behaviour problems were more prevalent in the manual social classes, "need" was high across all social groups. Just under a fifth of parents reported prior attendance at a parenting programme and 58% expressed interest in attending in the future. Interest in attending a parenting programme was not class related, but was predicted by the age of the eldest child and the existence of behaviour problems. CONCLUSION: Behaviour problems are an important public health issue. Findings support the use of a non-selective approach to the provision of parenting programmes in the UK.

Suicide pact survivors: some observations.

Interviews with seven survivors of four suicide pact paris are examined. In the majority of cases the instigator is more likely to be the male member of the pair. Absence of past suicidal behaviour, and some socio-cultural aspects surround the Indian pact member, in comparison with the West. The existing legal provisions relating to criminal liability for complicity in suicide of another person are summarized. The role and attitude of the Indian Penal Code in dealing with suicide pact survivors is discussed.

Stratospheric ozone depletion and the risk of non-melanoma skin cancer in a British population.

Quantitative estimation of the increased risk of non-melanoma skin cancer (NMSC) in British people that may result from depletion of the stratospheric ozone layer is given for the present generation of British people. For adults alive today continuing ozone depletion at current rates is predicted to result in a relatively small additional lifetime risk (< 5%) of NMSC, assuming no changes in climate, time spent outdoors, behaviour or clothing habits. The lifetime risk incurred by today's children, however, is 10%-15% greater than expected in the absence of ozone depletion. However, if the production and use of substances which deplete ozone are reduced, as expected under the current provisions of the Montreal Protocol, the increased lifetime risk of skin cancer is likely to be less than this estimate. These predicted increases in risk, resulting from greater solar ultraviolet exposure, can be offset by adopting changes to behaviour during the summer months which may involve spending less time outdoors, wearing appropriate clothing including wide-brimmed hats, applying topical sunscreens, or a combination of these.

Asthma self-management education.

Asthma self-management education is a fundamental component of asthma management guidelines. Self-management education should include the provision of information, self-monitoring, regular medical review and the provision of a written asthma management plan. Implementing this form of management can be challenging, this paper reviews the evidence supporting self-management education, provides recommendations and tools for delivering asthma education and discusses the challenges and solutions to implementing these recommendations. We have discussed ways to improve communication, develop patient partnerships and tailor management to facilitate behavioural change, adherence and self-management. Health Professionals providing education and guiding self-management require training to acquire and maintain the skills necessary to deliver this form of education. Provision of this training is important and can be achieved through varied methods of achieving competence.

A survey of dementia carers: doctors' communications, problem behaviours and institutional care.

A survey of carers belonging to the Alzheimer's Disease and Related Disorders Society (ADARDS) had three aims: (i) to investigate the process of health professionals providing information to patients and carers: (ii) to determine the nature of problems burdening carers; and (iii) to examine factors associated with institutional placement. Carers reported on deficiencies in the provision of information and indicated their preferences as to how the information should be given. ADARDS, general practitioners and other health professionals were reportedly helpful, with each appearing to have a role in providing information about dementia. Multiple problem behaviours were reported by most carers, especially difficulties with communication, the need for constant supervision and disruption to personal life. Institutional care was most highly correlated with dependency problems, severity of dementia and a non-spouse carer. Implications include the need for training of doctors in communication and education about dementia with particular attention to management of dependency problems.

Individual differences in parental care and behaviour profile in the convict cichlid: a correlation study.

We examined whether individual differences in patterns of parental care relate to individual differences in situations involving novelty, risk and aggression in the convict cichlid, Cichlasoma (Archocentrus) nigrofasciatum. Individual differences in situations of novelty and risk could be summarized along two axes: Freezing versus Activity and Activity-Inspection versus Freezing. However, these factors were not independent and formed a single higher-order dimension of general activity. Parental locomotor activity was negatively correlated with the Freezing versus Activity factor in females. Males that did little brood provisioning tended to be less active in the presence of a novel fish. Individuals that spent more time near their offspring at late brood stages were less inhibited in behavioural tests. Furthermore, extreme assortative mating by body size was found (r(S)=0.91). The cichlids also spawned assortatively by the factor Freezing versus Activity and by the general activity factor (r(S)>/=0.49), but not by the factor Activity- Inspection versus Freezing or by aggressiveness.
