Bronze Age moss fibre garments from Scotland – the jury’s out

In the light of recent discoveries of early to middle Bronze Age burials with mats and fibrous material in Scotland, for example at Langwell farm and Forteviot, it was deemed timely to re-evaluate earlier finds of this period, several of which were discovered and initially reported on nearly a century ago. As part of this research it was noted that three Bronze Age finds from the old literature were reported as clothing or shrouds made of hair moss (Polytrichum commune). Three of these are reassessed here, with a detailed re-examination of the “hair moss apron” from North Cairn Farm. Technological analysis of this find showed no evidence for the twining previously reported and SEM fibre analysis shows that it is unlikely to be hair moss or indeed Bronze Age. However, there is other evidence for hair moss artefacts from other British Bronze Age and Roman contexts. These suggest it is possible that hair moss fibre was used in Scotland in the Bronze Age, but that the North Cairn Farm fibrous object should no longer be considered among this evidence

Workplace Flexibility Practices in SMEs: Relationship with Performance via Redundancies, Absenteeism, and Financial Turnover

This workplace flexibility study uses primary data on private sector small and medium-sized enterprises (SMEs) in Lancashire, United Kingdom, collected in 2009 during the recent “credit crunch” recession. Key features include: (1) objective measures of SME performance; (2) a focus on the previously relatively neglected relationship between workplace flexibility practices (WFPs) and three SME performance indicators, namely, redundancies, absenteeism, and financial turnover; and (3) a timely contribution to research on SMEs. Numerical, functional, and cost WFPs analyses, via zero-inflated Poisson and linear regressions, control for SME and market characteristics. Despite SMEs having limited resources, the results show a significant section of SMEs to be innovative and entrepreneurial organizations, embracing advancements in employment relations regarding employee discretion, training, participative working arrangements, and/or job security. Moreover, results indicate that WFPs have the potential to assist SMEs in responding to periods of constrained demand. Flexitime and job sharing are associated with low permanent-employee redundancies. Training, job security, and family-friendly practices relate to low absenteeism with reductions of up to six annual days per worker. Job security and profit-related pay are associated with high financial turnover. Staff pay-freeze links with high financial turnover, but to the detriment of redundancies and absenteeism, whereas management pay-cuts or management pay-freeze relate to low financial turnover. On a cautionary note, spending cuts, often enforced by policymakers, may be of limited benefit to SMEs, and thus other approaches would appear more fruitful

PastPlace: the historical gazetteer service from the people who brought you A Vision of Britain through Time

The PastPlace API offers a simple web service, responding to a variety of queries by returning information from the same database as underlies the Vision of Britain web site, in a range of structured formats. These queries can be typed into a web browser as URLs, and the response viewed in the browser. However, the queries would more usually be sent by another server on the web, and the response processed by that server. That server might itself be creating web pages for use by the general public, but it might also be a cataloguing or records management system, using our API as a name authority. This poster is the first public description of the servic

THE EFFECT OF FOOD-SAFETY RELATED INFORMATION ON CONSUMERS' PREFERENCE: THE CASE OF BSE OUTBREAK IN JAPAN

This study analyzes consumers' responses to food-safety related information by evaluating if Japanese consumers have undergone a structural change in their preferences for meat due to the BSE outbreak in the country. The axiom of revealed preference is utilized to test the stability of preference in Japanese meat consumption. The matrix of weak form of revealed preference (WARP) is partitioned and Kruskal-Wallis statistics are derived to evaluate whether the switches of preference are transitory or due to a structural change. Empirical results show that Japanese meat demand has undergone a structural change, synchronized with the BSE outbreak in Japan in mid-September 2001.Food Consumption/Nutrition/Food Safety,

Does high involvement management improve worker wellbeing?

Employees exposed to high involvement management (HIM) practices have higher subjective wellbeing, fewer accidents but more short absence spells than “like” employees not exposed to HIM. These results are robust to extensive work, wage and sickness absence history controls. We present a model which highlights the possibility of higher short-term absence in the presence of HIM because it is more demanding than standard production and because multi-skilled HIM workers cover for one another’s short absences thus reducing the cost of replacement labour faced by the employer. We find direct empirical support for the assumptions in the model. Consistent with the model, because long-term absences entail replacement labour costs for HIM and non-HIM employers alike, long-term absences are independent of exposure to HIM.health; subjective wellbeing; sickness absence; job satisfaction; high involvement management; high performance work system

"The trauma of competition": the entry of Air Products Inc. into the industrial gases business in Britain and continental Europe 1947-1970

The British Oxygen Company (BOC) had a virtual monopoly on the supply of industrial gases (e.g. oxygen and acetylene) on the British market through the 1950s, when it was finally challenged by an American-based company, Air Products. Air Products Limited (APL) was able to undercut BOCs position, overcoming high barriers to entry to gain significant market share in this sector, which shares some features of network industries. Factors in this success included conditions imposed by the Board of Trade, APL’s innovations, BOC’s slow response, and favourable market conditions. APL’s success had implications for the internationalisation of the industrial gases industry

Relational Identities and Other-Than-Human Agency in Archaeology

Relational Identities and Other-than-Human Agency in Archaeology explores the benefits and consequences of archaeological theorizing on and interpretation of the social agency of nonhumans as relational beings capable of producing change in the world. The volume cross-examines traditional understanding of agency and personhood, presenting a globally diverse set of case studies that cover a range of cultural, geographical, and historical contexts. Agency (the ability to act) and personhood (the reciprocal qualities of relational beings) have traditionally been strictly assigned to humans. In case studies from Ghana to Australia to the British Isles and Mesoamerica, contributors to this volume demonstrate that objects, animals, locations, and other nonhuman actors also potentially share this ontological status and are capable of instigating events and enacting change. This kind of other-than-human agency is not a one-way transaction of cause to effect but requires an appropriate form of reciprocal engagement indicative of relational personhood, which in these cases, left material traces detectable in the archaeological record. Modern dualist ontologies separating objects from subjects and the animate from the inanimate obscure our understanding of the roles that other-than-human agents played in past societies. Relational Identities and Other-than-Human Agency in Archaeology challenges this essentialist binary perspective. Contributors in this volume show that intersubjective (inherently social) ways of being are a fundamental and indispensable condition of all personhood and move the debate in posthumanist scholarship beyond the polarizing dichotomies of relational versus bounded types of persons. In this way, the book makes a significant contribution to theory and interpretation of personhood and other-than-human agency in archaeology.https://cupola.gettysburg.edu/books/1141/thumbnail.jp

Actin, α-actinin, and tropomyosin interaction in the structural organization of actin filaments in nonmuscle cells

During the spreading of a population of rat embryo cells, approximately 40% of the cells develop a strikingly regular network which precedes the formation of the straight actin filament bundles seen in the fully spread out cells. Immunofluorescence studies with antibodies specific for the skeletal muscle structural proteins actin, α-actinin, and tropomyosin indicate that this network is composed of foci containing actin and α-actinin, connected by tropomyosin-associated actin filaments. Actin filaments, having both tropomyosin and α-actinin associated with them, are also seen to extend from the vertices of this network to the edges of the cell. These results demonstrate a specific interaction of α-actinin and tropomyosin with actin filaments during the assembly and organization of the actin filament bundles of tissue culture cells. The three-dimensional network they form may be regarded as the structural precursor and the vertices of this network as the organization centers of the ultimately formed actin filament bundles of the fully spread out cells

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments

TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins. To assess the activity of apple (Malus domestica) pollen TGase on the functional properties of actin and tubulin, TGase was prepared from apple pollen by hydrophobic interaction chromatography and assayed on actin and tubulin purified from the same cell type. The enzyme catalysed the incorporation of putrescine in the cytoskeleton monomers. When tested on actin filaments, pollen TGase induced the formation of high-molecular-mass aggregates of actin. Use of fluorescein– cadaverine showed that the labelled polyamine was incorporated into actin by pollen TGase, similar to with guinea pig liver TGase. The pollen TGase also reduced the enzyme activity and the binding of myosin to TGase-treated actin filaments. Polymerization of tubulin in the presence of pollen TGase also yielded the formation of high molecular mass aggregates. Furthermore, the pollen TGase also affected the binding of kinesin to microtubules and reduced the motility of microtubules along kinesincoated slides. These results indicate that the pollen tube TGase can control different properties of the pollen tube cytoskeleton (including the ability of actin and tubulin to assemble and their interaction with motor proteins) and consequently regulate the development of pollen tubes
