Biting Behaviour

AbstractThe development of adverse behaviour in group–housed growing/ finishing pigs with intact tails was studied in a straw–flow housing system and in a part–slatted system with a commercial enrichment object. Food intake, body weight and behaviour were monitored over the finishing period, with tail biting outbreaks defined as an occasion where three or more pigs within a group had freshly damaged tails and tail biting behaviour was ongoing. Data from the two systems were analysed to identify tail–biting outbreaks and behavioural changes over time. Levels of pig manipulation were higher in the part–slatted system. Over time, pigs in both systems showed reduced interest in the enrichment provided, but not in each other. Despite the presence of the enrichment device, tail biting occurred in all groups in the part–slatted system, but only 1/12 groups in the straw–flow system. The amount of time occupied by manipulation of the enrichment provided was very significantly higher for straw than for the commercial object. Better design of enrichment strategies is therefore needed and should be based on species–relevant requirements.

This study identifies interplay between the localization processes and formal as well as informal institutions in a specific context. Particularly the changes over time in institutions and localization processes are in focus. A longitudinal study of institutional changes in local management has been conducted from 1997 to 2002 among local CEOs, chief accountants and production managers in a Danish SME, using mainly qualitative methods. Data have been compared to primary data from similar companies in Estonia, Latvia and Lithuania. The study has resulted in establishing a model for comparing interplay between localization processes in SMEs and the formal and informal institutions in different transition and post‐transition economies.

Abstract Aging is associated with numerous changes at all levels of biological organization. Harnessing this information to develop measures that accurately and reliably quantify the biological aging process will require longitudinal modeling and incorporation of systems level approaches. We will describe applications of network modeling for longitudinal multi-system biomarker data. Using data from the Baltimore Longitudinal Study of Aging (BLSA) we are able to generate systems level models of biological and physiological function, and then demonstrate how these networks change with age. We will also link systems-level aging changes to hallmarks of aging, including epigenetic alterations, senescence, mitochondrial dysfunction, and proteostasis. Given the complexity of the biological aging process, modeling of systems dynamics over time will both lead to the development of better biomarkers of aging, and also inform our conceptualization of how alterations at the molecular level propagate up levels of organization to eventually influence morbidity and mortality risk.

Based on data from the Bangor Longitudinal Study of Ageing (BLSA) 1979–1999, this paper examines changes over time in the intergenerational relationships of older people (aged 65+ in 1979). The analysis uses quantitative and qualitative data to discuss changes from 1979–1999 for those respondents who survived in the community to 1999. It looks at mothers’ and fathers’ relationships with their adult children, grandmother and grandfather relationships with grandchildren and relationships between aunts and uncles with nieces and nephews. It identifies four different patterns of intergenerational relationships showing how the rural employment structure impacts on family structure, migration and support patterns.

The purpose of this study was to examine patterns in high school career and technical education (CTE) coursetaking by gender and race/ethnicity across two cohorts of students over time. Using high school transcript data from the Education Longitudinal Study of 2002 (ELS:2002) and the High School Longitudinal Study of 2009 (HSLS:09), we examined participation in CTE both overall and disaggregated by field of study. While there were some differences by gender and race/ethnicity in overall CTE participation, disaggregating by field of study revealed wide variation in participation rates in each field. We found large and sustained differences in participation across CTE fields of study by gender as well as pronounced patterns by race/ethnicity, with some changes over time. Overall, these gender and racial/ethnic differences were notable because they persisted even after controlling for other potential explanatory factors.

Abstract Background Lean is commonly adopted in healthcare to increase quality of care and efficiency. Few studies of Lean involve staff-related outcomes, and few have a longitudinal design. Thus, the aim was to examine the extent to which changes over time in Lean maturity are associated with changes over time in care-giving, thriving and exhaustion, as perceived by staff, with a particular emphasis on the extent to which job demands and job resources, as perceived by staff, have a moderated mediation effect. Method A longitudinal study with a correlational design was used. In total, 260 staff at 46 primary care units responded to a web survey in 2015 and 2016. All variables in the study were measured using staff ratings. Ratings of Lean maturity reflect participants’ judgements regarding the entire unit; ratings of care-giving, thriving, exhaustion and job demands and resources reflect participants’ judgements regarding their own situation. Results First, over time, increased Lean maturity was associated with increased staff satisfaction with their care-giving and increased thriving, mediated by increased job resources. Second, over time, increased Lean maturity was associated with decreased staff exhaustion, mediated by decreased job demands. No evidence was found showing that job demands and job resources had a moderated mediation effect. Conclusion The results indicate that primary care staff may benefit from working in organizations characterized by high levels of Lean maturity and that caregiving may also be improved as perceived by staff.

A novel approach to data extraction and synthesis was used to explore the connections between research priorities, understanding and practice improvement associated with family bereavement in the context of the potential for organ donation. Conducting the review as a qualitative longitudinal study highlighted changes over time, and extraction of citation-related data facilitated an analysis of the interaction in this field. It was found that lack of ‘communication’ between researchers contributes to information being ‘lost’ and then later ‘rediscovered’. It is recommended that researchers should plan early for dissemination and practice improvement to ensure that research contributes to change.
