IFPOC Symposium:Discovering antecedents and consequences of complex change recipients' reactions to organizational change.

IFPOC symposium: Discovering antecedents and consequences of complex change recipients' reactions to organizational change Chairs: Maria Vakola (Athens University of Economics and Business) & Karen Van Dam (Open University) Discussant: Mel Fugate (American University, Washington, D.C) State of the art Organisations are required to continuously change and develop but there is a high failure rate associated with change implementation success. In the past two decades, change researchers have started to investigate change recipients' reactions to change recognizing the crucial role of these reactions for successful change. This symposium aims at identifying and discussing the complex processes that underlie the relationships among antecedents, reactions and outcomes associated with organizational change. New perspective / contributions This symposium consists of five studies that extend our knowledge in the field by (i) providing an analysis of change recipients' reactions going beyond the dichotomous approaches (acceptance or resistance) (ii) revealing understudied antecedents-reactions and reactions-consequences patterns and relationships (iii) shedding light on the role of contextual factors i.e team climate and individual factors i.e emotion regulation on the adaptation to change. This symposium is based on a combination of both quantitative (i.e diary, survey) and qualitative (i.e interviews) research methodology. Research / practical implications This symposium aims to increase our understanding of the complex processes associated with change recipients' reactions to change. Discovering how these reactions are created and what are their results may reveal important contingencies that can explain how positive organizational outcomes during times of change can be stimulated which is beneficial for both researchers and practitioners

Legacy pollutants are declining in Great Skuas (Stercorarius skua) but remain higher in Faroe Islands than in Scotland

To monitor environmental pollutants in Faroese biota, samples from a top predator were analysed and put into a spatial and temporal context. Analysis of 20 Great Skua eggs sampled in 2012 from the Faroe Islands showed >70 % lower concentrations of legacy persistent organic pollutants (POPs) than in samples analysed in 1977. The 2012 Faroese eggs showed higher concentrations than for eggs in Shetland from about the same period (2008). Eggshells were analysed for sub-lethal effects but there were no detectable effects of legacy POP levels on eggshell colour or thickness. A temporal decline in legacy POPs would indicate a reduction in the general pollutant levels present in the environment as has been shown in other areas of the North Atlantic, but there are significant geographic differences in POPs levels likely due to differences in diet resulting in significantly different exposures on a relatively limited spatial scale

Illicit drug use and cerebral microbleeds in stroke and transient ischemic attack patients

Background: Cerebral microbleeds (CMB) signal cerebral small vessel disease and are associated with ischemic stroke (IS) incidence, recurrence, and complications. While illicit drug use (IDU) is associated with cerebral small vessel disease, the association between CMB and IDU is understudied. We sought to delineate differences in vascular risk factors between IDU and CMB and determine the effect of this relationship on outcomes in IS/transient ischemic attack (TIA) patients. Methods: We included 2001 consecutive IS and TIA patients (years 2009-2018) with a readable T2*gradient-echo MRI sequence. CMB rating followed standardized guidelines and CMB were grouped topographically into lobar, deep or infratentorial. IDU data (history and/or urine toxicology) was available for 1746 patients. The adverse composite outcome included pneumonia, urinary tract infection, deep venous thrombosis or death during hospitalization. Good functional outcome was defined as modified Rankin scale score < 3 and ambulatory on discharge. Univariate analysis was used to assess vascular risk factors and multivariable logistic regression was used to characterize the IDU/CMB relationship on outcomes. Results: We observed IDU in 13.8 % (n=241), and CMB in 32.9% (n=575, 53.8% lobar, 27.3% deep and 18.8% infratentorial). Patients with IDU and at least one CMB were older (53.6±10.5 vs. 56.9±11.5, p=0.04), had a lower BMI (28.1±5.9 vs. 26.6±4.4, p=0.04), and were more likely to have had a previous IS/TIA (25.1% vs. 41.9%, p=0.01). IDU trended higher for those with severe CMB (10+) compared with those without CMB and 1-9 CMB (25% [n=9] vs 14.3% [n=1171] and 12.1% [n=65] respectively; p=0.07) without individual drug deviations from this pattern. Adverse and good functional outcomes were observed in 177 and 905 total patients, respectively. No significant interaction was observed between IDU and CMB with either adverse or functional composite outcomes. Conclusion: IDU prevalence was high in our urban study population, and showed a borderline association with increasing CMB burden. Patients with CMB and IDU history were older and more likely to have had a previous IS/TIA. Further studies are required to clarify the clinical consequences related to the relationship between IDU and CMB.Author Disclosures: B. Petrie: None. H. Lau: None. F. Cajiga-Pena: None. S.
