The Impact of Training on Labour Mobility

The paper investigates the impact of different types of training on the mobility expectations of workers, using two new data sets, one of individuals the other of firms. The innovation is that the data incorporate measures of the degree of transferability of training, improved information on the sources of sponsorship, and judgements about the aims and outcomes of training. We find that most training episodes produce some transferable skills and that most transferable training is paid for by employers. Overall, training appears to have little impact on mobility. It has no impact on mobility in 3 out every 5 cases; the remaining cases are split equally between those where training increases and those where it decreases mobility. We estimate the determinants of mobility outcomes using an ordered probit analysis. Consistent with theory, we find that training is more likely to lead to lower mobility when it is less transferable to other firms, sponsored by firms, and where it has objectives and outcomes aimed at increasing the identification of employees with corporate objectives

Getting the measure of training: A report on training statistics in Britain

Despite the prominence of work-based training in British national policy debate, published statistics fail to give solid data on training volume or quality. The Labor Force Survey, commonly used to give a picture of increasing training, shows proportions of training over any 4-week period rose from 10.8 percent in 1985 to 15.2 percent in 1994. Closer analysis indicates that, spread over all employees, average time spent on off-the-job training was 39 minutes per week per employee in 1985 and 40 minutes in 1994. Use of proxy interviewing techniques makes reliability of the participation rate questionable. Current surveys provide little useful information about trends in training quality and none about trends in training sponsorship. Proposed typologies of training are based on training quantity, quality, and sponsorship. To develop this proposition, two surveys have been conducted--one focused on individuals, the other on employing organizations--to examine the quantity and quality of employee training in Britain and show the occurrence of much undetected training through teach-yourself methods. The individual survey included interviews with a random sample of 1,539; the employer survey received responses from 149 of 742 large employers and 313 of 1,570 small employers. Findings indicated the following: 34 percent of training is certified; over 80 percent of employees believe they are getting transferable skills; 63 percent of employers fully fund training; the majority of employees felt the aim of training was to improve their skills for doing their job; and relatively few felt their mobility would be affected by their training.

Oviposition Site Selection by the Dengue Vector Aedes aegypti and Its Implications for Dengue Control

Controlling the mosquito Aedes aegypti is of public health importance because, at present, it is the only means to stop dengue virus transmission. Implementing successful mosquito control programs requires understanding what factors regulate population abundance, as well as anticipating how mosquitoes may adapt to control measures. In some species of mosquitoes, females choose egg-laying sites to improve the survival and growth of their offspring, a behavior that ultimately influences population distribution and abundance. In the current study, we tested whether Ae. aegypti actively choose the containers in which they lay their eggs and determined what cues are most relevant to that process. We also explored whether females select containers that provide the most food for their larval progeny. Surprisingly, egg-laying females were most attracted to sites containing other immature Ae. aegypti, rather than to sites containing the most food. We propose that this behavior may contribute to density-dependent competition for food among larvae and play a larger role than previously thought in regulating Ae. aegypti populations. We recommend that accounting for, and even taking advantage of, this natural behavior will lead to more effective strategies for dengue prevention

Investigation of hospital discharge cases and SARS-CoV-2 introduction into Lothian care homes

Background The first epidemic wave of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Scotland resulted in high case numbers and mortality in care homes. In Lothian, over one-third of care homes reported an outbreak, while there was limited testing of hospital patients discharged to care homes. Aim To investigate patients discharged from hospitals as a source of SARS-CoV-2 introduction into care homes during the first epidemic wave. Methods A clinical review was performed for all patients discharges from hospitals to care homes from 1st March 2020 to 31st May 2020. Episodes were ruled out based on coronavirus disease 2019 (COVID-19) test history, clinical assessment at discharge, whole-genome sequencing (WGS) data and an infectious period of 14 days. Clinical samples were processed for WGS, and consensus genomes generated were used for analysis using Cluster Investigation and Virus Epidemiological Tool software. Patient timelines were obtained using electronic hospital records. Findings In total, 787 patients discharged from hospitals to care homes were identified. Of these, 776 (99%) were ruled out for subsequent introduction of SARS-CoV-2 into care homes. However, for 10 episodes, the results were inconclusive as there was low genomic diversity in consensus genomes or no sequencing data were available. Only one discharge episode had a genomic, time and location link to positive cases during hospital admission, leading to 10 positive cases in their care home. Conclusion The majority of patients discharged from hospitals were ruled out for introduction of SARS-CoV-2 into care homes, highlighting the importance of screening all new admissions when faced with a novel emerging virus and no available vaccine

SARS-CoV-2 Omicron is an immune escape variant with an altered cell entry pathway

Vaccines based on the spike protein of SARS-CoV-2 are a cornerstone of the public health response to COVID-19. The emergence of hypermutated, increasingly transmissible variants of concern (VOCs) threaten this strategy. Omicron (B.1.1.529), the fifth VOC to be described, harbours multiple amino acid mutations in spike, half of which lie within the receptor-binding domain. Here we demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273. These data were mirrored by a substantial reduction in real-world vaccine effectiveness that was partially restored by booster vaccination. The Omicron variants BA.1 and BA.2 did not induce cell syncytia in vitro and favoured a TMPRSS2-independent endosomal entry pathway, these phenotypes mapping to distinct regions of the spike protein. Impaired cell fusion was determined by the receptor-binding domain, while endosomal entry mapped to the S2 domain. Such marked changes in antigenicity and replicative biology may underlie the rapid global spread and altered pathogenicity of the Omicron variant

Improving productivity - Opening the black box.

Hourly productivity levels in the UK still remain behind those in some competitor countries. The government devotes much policy attention to enhancing productivity and continues to emphasise its five drivers—investment, innovation, skills, enterprise, and competition. This article argues that it is investment broadly defined that is the key to sustained productivity improvement. The emphasis should be on improving productivity simultaneously with improving the quality of production. Only thus will the gains be widely shared. In achieving these aims there are two prerequisites for policy-makers. The first is to ensure better coordination of policy than appears to be currently achieved by the present departmental structures in Whitehall. The second is to recognize fully the long and complex chain of causation that can be triggered by pulling on one policy lever. Such complexity can only be fully understood by more research on what actually goes on inside the black box of the organization
