The Relationship Between Laughter Intensity and Perceived Humour

There is a long history of recognizing a continuum in social signals of positive affect, with the continuum ranging from mild amusement signals to strong laughter. However there has been little systematic effort to assess what this continuum might mean. We present data that shows that incorporating intensity measures of laughter into laughter research is an important component and that there is a strong relationship between laughter intensity and humour. This may be intuitively obvious but the strength of the relationship suggests that intensity measures should be included in all laughter research.

Research in Progress: Medical Research Council United Kingdom Refractory Asthma Stratification Programme (RASP-UK)

The UK Refractory Asthma Stratification Programme(RASP-UK) will explore novel biomarker stratificationstrategies in severe asthma to improve clinicalmanagement and accelerate development of newtherapies. Prior asthma mechanistic studies have notstratified on inflammatory phenotype and theunderstanding of pathophysiological mechanisms inasthma without Type 2 cytokine inflammation is limited.RASP-UK will objectively assess adherence tocorticosteroids (CS) and examine a novel compositebiomarker strategy to optimise CS dose; this will alsoaddress what proportion of patients with severe asthmahave persistent symptoms without eosinophilic airwaysinflammation after progressive CS withdrawal. There will be interactive partnership with the pharmaceutical industry to facilitate access to stratified populations for novel therapeutic studies.

The Meaning of Drug Use among Homeless Young People:A longitudinal pathways analysis

A strong link between drug use and homelessness has long since been documented in the international literature. However, much of the research has concentrated on the direction of the relationship between drug use and homelessness, seeking to establish drug use as a cause or consequence of homelessness, with far less attention to the intersection of drug and homeless ‘careers’. This paper examines the drug and homeless pathways of young people who are participants in a qualitative longitudinal study of homeless youth in Dublin, Ireland. The findings highlight downward drug transitions as associated with exiting homelessness and continued or escalated consumption as associated with remaining homeless. Analyses of the meanings young people attach to drug use over time reveal the importance of housing as an enabler to engaging with treatment and as assisting the process of becoming and remaining drug free. Young people who remained homeless did not accept their situations, as ‘acculturation’ accounts would suggest; rather, they aspired to changing their situations. However, they also face strong barriers to accessing housing which in turn hamper their efforts to address the matter of their drug use. The implications for how the homeless/drug use ‘nexus’ is conceptualised and understood, as well as implications for policy, are discussed.

Trends and Determinants of Work-Retirement Transitions under Changing Institutional Conditions: Germany, England and Japan compared

Many governments world-wide are promoting longer working life due to the social and economic repercussions of demographic change. However, not all workers are equally able to extend their employment careers. Thus, while national policies raise the overall level of labour market participation, they might create new social and labour market inequalities. This paper explores how institutional differences in the United Kingdom, Germany and Japan affect individual retirement decisions on the aggregate level, and variations in individuals’ degree of choice within and across countries. We investigate which groups of workers are disproportionately at risk of being ‘pushed’ out of employment, and how such inequalities have changed over time. We use comparable national longitudinal survey datasets focusing on the older population in England, Germany and Japan. Results point to cross-national differences in retirement transitions. Retirement transitions in Germany have occurred at an earlier age than in England and Japan. In Japan, the incidence of involuntary retirement is the lowest, reflecting an institutional context prescribing that employers provide employment until pension age, while Germany and England display substantial proportions of involuntary exits triggered by organisational-level redundancies, persistent early retirement plans or individual ill-health.

HRM and the employment of older workers: Germany and Britain compared

This study examines Human Resource Management (HRM) policies and practices towards older workers in Britain and Germany. While it is widely suggested that older workers have to be better integrated into the labour market, youth-centric HRM is still prevalent. However, HRM is shaped by multiple and contradictory pressures from the international and national institutional environments. We test this dynamic by analysing two national surveys, the German firm panel (IAB)1 and the British Workplace and Employment Relations Survey (WERS).2 Our findings suggest that the institutional environment shapes HR policies and practices distinctively in both countries. We find that age discrimination at the workplace is more prevalent in Germany than in Britain, which can be explained by divergent institutional patterns. As a result, we argue that although both countries will have to continue fostering an age-neutral HR approach, this has to take country-specific institutional peculiarities into account.

In Deutschland mehr Vorbehalte gegenüber älteren Arbeitnehmern: ein deutsch-britischer Vergleich

Infolge steigender Lebenserwartung sowie sinkender Geburtenraten wird das Durchschnittsalter der Bevölkerung in den meisten Industrienationen in den kommenden 50 Jahren stark ansteigen. Zur gleichen Zeit scheidet nach wie vor die Mehrzahl älterer Arbeitnehmer vor Erreichen der gesetzlichen Altersgrenze aus dem Arbeitsmarkt aus. Dies hat sowohl negative Auswirkungen auf die Finanzierbarkeit sozialer Sicherungssysteme als auch langfristig auf die Verfügbarkeit qualifizierter Arbeitnehmer am Arbeitsmarkt. Nationale Regierungen verfolgen daher gegenwärtig verschiedene Maßnahmen mit dem Ziel, die Arbeitsmarktbeteiligung älterer Arbeitnehmer zu erhöhen (OECD 2006). Diese Maßnahmen werden jedoch zum Teil durch die Strategien des betrieblichen Personalmanagements konterkariert, die oft noch jugendzentristisch ausgeprägt sind und ältere Mitarbeiter bei Einstellung, Beförderung, Weiterbildung sowie bei Arbeitsplatz- und Arbeitszeitgestaltung direkt oder indirekt benachteiligen (Bellmann et al. 2003).

EGF61 polymorphism predicts complete pathologic response to cetuximab-based chemoradiation independent of KRAS status in locally advanced rectal cancer patients

BACKGROUND: Cetuximab has shown significant clinical activity in metastatic colon cancer. However, cetuximab-containing neoadjuvant chemoradiation has not been shown to improve tumor response in locally advanced rectal cancer patients in recent phase I/II trials. We evaluated functional germline polymorphisms of genes involved in epidermal growth factor receptor pathway, angiogenesis, antibody-dependent cell-mediated cytotoxicity, DNA repair, and drug metabolism, for their potential role as molecular predictors for clinical outcome in locally advanced rectal cancer patients treated with preoperative cetuximab-based chemoradiation.

METHODS: 130 patients (74 men and 56 women) with locally advanced rectal cancer (4 with stage II, 109 with stage III, and 15 with stage IV, 2 unknown) who were enrolled in phase I/II clinical trials treated with cetuximab-based chemoradiation in European cancer centers were included. Genomic DNA was extracted from formalin-fixed paraffin-embedded tumor samples and genotyping was done by using PCR-RFLP assays. Fisher's exact test was used to examine associations between polymorphisms and complete pathologic response (pCR) that was determined by a modified Dworak classification system (grade III vs. grade IV: complete response).

RESULTS: Patients with the epidermal growth factor (EGF) 61 G/G genotype had pCR of 45% (5/11), compared with 21% (11/53) in patients heterozygous, and 2% (1/54) in patients homozygous for the A/A allele (P < 0.001). In addition, this association between EGF 61 G allele and pCR remained significant (P = 0.019) in the 59 patients with wild-type KRAS.

CONCLUSION: This study suggested EGF A+61G polymorphism to be a predictive marker for pCR, independent of KRAS mutation status, to cetuximab-based neoadjuvant chemoradiation of patients with locally advanced rectal cancer.
