Research performance and the organizational effectiveness of universities

Purpose The purpose of this paper is to test Shattock’s legacy reputation thesis that non-leading universities in the UK face insuperable resource barriers to entering the leading group. Design/methodology/approach Employing regression analysis, the authors examine whether prioritizing research performance is a viable strategy for non-leading UK universities aiming to improve their organizational effectiveness. The dependent variable, organizational effectiveness, is measured by the annual Guardian rankings of universities. The main independent variable, research performance, is measured using “research power” (“RP”). RP is derived from the UK Research Excellence Framework. Findings For 2008-2014, the authors find that changes in research performance impacted university rankings. However, the authors also find that changes to the rankings are largely confined to non-leading universities and have not led to these institutions breaking into the group of leading universities. Therefore, Shattock’s thesis is supported. Practical implications Failing to maintain research performance can have significant negative consequences for the rankings of non-leading universities. Originality/value This is the first study that examines the relationship between the research performance of universities in the UK with a measure of their overall organizational effectiveness

A multilevel analysis of the use of individual pay-for-performance systems

Compensation systems such as individualized pay for performance (I-PFP) schemes for employees represent an important approach to aligning employer-employee interests. However, the adoption of I-PFP is much less common in many countries than in the USA. Employing a multi-level analysis of over 4,000 firms in 26 countries, we explore determinants of its adoption. At the country level we distinguish between cultural and institutional (labor regulation institutions) influences. At the firm level, we distinguish firms that view HR as strategically important and firms that are foreign-owned. On the one hand, our findings indicate that both cultural and institutional effects at country level significantly influence the adoption of I-PFP. On the other hand, senior managers’ agency counts. We find the effect of labor regulation on I-PFP to be mediated by its effects on labor union influence and we find the effects of culture on I-PFP to be entirely mediated by labor regulation and (country level) union influence

‘We treat them all the same’: the attitudes, knowledge and practices of staff concerning old/er lesbian, gay, bisexual and trans residents in care homes

On the basis of a survey of 187 individuals, including service managers and direct care staff, we propose three related arguments. First, whilst employees’ attitudes generally indicate a positive disposition towards LGBT residents, this appears unmatched by the ability to recognise such individuals and knowledge of the issues and policies affecting LGBT people. Statements such as, ‘We don’t have any [LGBT residents] at the moment’ and ‘I/we treat them all the same’ were common refrains in responses to open-ended questions. They suggest the working of heteronormativity which could deny sexual and identity difference. Second, failure to recognise the distinct health and social care needs of LGBT residents means that they could be subject to a uniform service, which presumes a heterosexual past and cisgender status (compliance with ascribed gender), which risks compounding inequality and invisibility. Third, LGBT residents could be obliged to depend largely on the goodwill, knowledge and reflexivity of individual staff (including people of faith) to meet care and personal needs, though such qualities were necessary but not sufficient conditions for inclusion and no substitute for collective practices (involving commitment to learn about LGBT issues) that become integral to care homes’ everyday functioning. A collective approach is key to advancing inclusion, implementation of legal rights to self-expression and securing equality through differentiated provision.Peer reviewedFinal Accepted Versio

Genome-wide association, prediction and heritability in bacteria with application to Streptococcus pneumoniae

Whole-genome sequencing has facilitated genome-wide analyses of association, prediction and heritability in many organisms. However, such analyses in bacteria are still in their infancy, being limited by difficulties including genome plasticity and strong population structure. Here we propose a suite of methods including linear mixed models, elastic net and LD-score regression, adapted to bacterial traits using innovations such as frequency-based allele coding, both insertion/deletion and nucleotide testing and heritability partitioning. We compare and validate our methods against the current state-of-art using simulations, and analyse three phenotypes of the major human pathogen Streptococcus pneumoniae, including the first analyses of minimum inhibitory concentrations (MIC) for penicillin and ceftriaxone. We show that the MIC traits are highly heritable with high prediction accuracy, explained by many genetic associations under good population structure control. In ceftriaxone MIC, this is surprising because none of the isolates are resistant as per the inhibition zone criteria. We estimate that half of the heritability of penicillin MIC is explained by a known drug-resistance region, which also contributes a quarter of the ceftriaxone MIC heritability. For the within-host carriage duration phenotype, no associations were observed, but the moderate heritability and prediction accuracy indicate a moderately polygenic trait.Peer reviewe

Diversification of bacterial genome content through distinct mechanisms over different timescales

Bacterial populations often consist of multiple co-circulating lineages. Determining how such population structures arise requires understanding what drives bacterial diversification. Using 616 systematically sampled genomes, we show that Streptococcus pneumoniae lineages are typically characterized by combinations of infrequently transferred stable genomic islands: those moving primarily through transformation, along with integrative and conjugative elements and phage-related chromosomal islands. The only lineage containing extensive unique sequence corresponds to a set of atypical unencapsulated isolates that may represent a distinct species. However, prophage content is highly variable even within lineages, suggesting frequent horizontal transmission that would necessitate rapidly diversifying anti-phage mechanisms to prevent these viruses sweeping through populations. Correspondingly, two loci encoding Type I restriction-modification systems able to change their specificity over short timescales through intragenomic recombination are ubiquitous across the collection. Hence short-term pneumococcal variation is characterized by movement of phage and intragenomic rearrangements, with the slower transfer of stable loci distinguishing lineages

Horizontal DNA transfer mechanisms of bacteria as weapons of intragenomic conflict

Horizontal DNA transfer (HDT) is a pervasive mechanism of diversification in many microbial species, but its primary evolutionary role remains controversial. Much recent research has emphasised the adaptive benefit of acquiring novel DNA, but here we argue instead that intragenomic conflict provides a coherent framework for understanding the evolutionary origins of HDT. To test this hypothesis, we developed a mathematical model of a clonally descended bacterial population undergoing HDT through transmission of mobile genetic elements (MGEs) and genetic transformation. Including the known bias of transformation toward the acquisition of shorter alleles into the model suggested it could be an effective means of counteracting the spread of MGEs. Both constitutive and transient competence for transformation were found to provide an effective defence against parasitic MGEs; transient competence could also be effective at permitting the selective spread of MGEs conferring a benefit on their host bacterium. The coordination of transient competence with cell-cell killing, observed in multiple species, was found to result in synergistic blocking of MGE transmission through releasing genomic DNA for homologous recombination while simultaneously reducing horizontal MGE spread by lowering the local cell density. To evaluate the feasibility of the functions suggested by the modelling analysis, we analysed genomic data from longitudinal sampling of individuals carrying Streptococcus pneumoniae. This revealed the frequent within-host coexistence of clonally descended cells that differed in their MGE infection status, a necessary condition for the proposed mechanism to operate. Additionally, we found multiple examples of MGEs inhibiting transformation through integrative disruption of genes encoding the competence machinery across many species, providing evidence of an ongoing "arms race." Reduced rates of transformation have also been observed in cells infected by MGEs that reduce the concentration of extracellular DNA through secretion of DNases. Simulations predicted that either mechanism of limiting transformation would benefit individual MGEs, but also that this tactic's effectiveness was limited by competition with other MGEs coinfecting the same cell. A further observed behaviour we hypothesised to reduce elimination by transformation was MGE activation when cells become competent. Our model predicted that this response was effective at counteracting transformation independently of competing MGEs. Therefore, this framework is able to explain both common properties of MGEs, and the seemingly paradoxical bacterial behaviours of transformation and cell-cell killing within clonally related populations, as the consequences of intragenomic conflict between self-replicating chromosomes and parasitic MGEs. The antagonistic nature of the different mechanisms of HDT over short timescales means their contribution to bacterial evolution is likely to be substantially greater than previously appreciated

Genome-wide identification of lineage and locus specific variation associated with pneumococcal carriage duration.

Streptococcus pneumoniae is a leading cause of invasive disease in infants, especially in low-income settings. Asymptomatic carriage in the nasopharynx is a prerequisite for disease, but variability in its duration is currently only understood at the serotype level. Here we developed a model to calculate the duration of carriage episodes from longitudinal swab data, and combined these results with whole genome sequence data. We estimated that pneumococcal genomic variation accounted for 63% of the phenotype variation, whereas the host traits considered here (age and previous carriage) accounted for less than 5%. We further partitioned this heritability into both lineage and locus effects, and quantified the amount attributable to the largest sources of variation in carriage duration: serotype (17%), drug-resistance (9%) and other significant locus effects (7%). A pan-genome-wide association study identified prophage sequences as being associated with decreased carriage duration independent of serotype, potentially by disruption of the competence mechanism. These findings support theoretical models of pneumococcal competition and antibiotic resistance
