When Labour and Capital Collude: The Varieties of Welfare Capitalism and Early Retirement in Europe, Japan and the USA. CES Germany & Europe Working Papers, No. 00.4, 2000

The institutionalisation of early retirement has become a universal feature of postwar industrial economies, though there are significant cross-national variations. This paper studies the impact of different types of welfare regimes, production systems and labour relations on early exit from work. After an analysis of the main trends, the paper discusses the costs and benefits of early retirement for the various actors — labour, capital and the state — at different levels. The paper outlines both the "pull” and "push” factors of early exit. It first compares the distinct welfare state regimes and private occupational pensions in their impact on early retirement. Then it looks at the labour-shedding strategies inherent to particular employment regimes, production systems and financial governance structures. Finally, the impact of particular industrial relations systems, and especially the role of unions is discussed. The paper finds intricate "institutional complementarities” between particular welfare states, production regimes and industrial relations systems, and these structure the incentives under which actors make decisions on work and retirement. The paper argues that the "collusion” between capital, labour and the state in pursuing early retirement is not merely following a labour-shedding strategy to ease mass unemployment, but also caused by the need for economic restructuration, the downsizing pressures from financial markets, the maintenance of peaceful labour relations, and the consequences of a seniority employment system.

Capacity mechanisms. A credibility test for the Energy Union? EPC Policy Brief, 11 June 2015

Recently, few aspects of the debate surrounding energy have been as divisive as capacity markets. After having given a green light to a capacity remuneration scheme in the UK in 2014, the EU Commission is now considering starting a sector inquiry in several member states. This paper aims at shedding some light on what capacity markets are about and what are the EU-specific implications, arguing that the debate is ill framed within a market context still focused on conventional power generation, and making the case for a coordinated approach to solve the fallacies of the present system.

Taboo Language and Illness Online: The Use of Specific Emoticons and Graphic Signs to Talk about HIV/AIDS in South Africa

South Africa is one of the countries most affected by HIV/AIDS: According to 2014 UNAIDS data 6.8 million South Africans live with HIV/AIDS, which means a 18.9% prevalence rate among adults (15-49 years old). Despite this strong presence of HIV/AIDS in South African society it remains relatively stigmatized and is not openly talked about. The silence about HIV/AIDS maintained in everyday conversations and the superstitions associated with this illness have led to the creation of a taboo language. This study aims at shedding light on how South African users resort to specific emoticons and graphic signs to talk about HIV/AIDS online. For this purpose 368 Facebook status updates and comments concerning HIV/AIDS and its side effects were analysed. All participants, aged 14-48, lived at the moment of data collection in Cape Town, in the Cape Flats area. The online conversations investigated are mainly in English mixed with Afrikaans and/or Xhosa. The emoticons and graphic signs in most cases display a graphic depiction of the physical (and mental) effects of the illness. These linguistic and semiotic practices employed on Facebook provide insight into how Capetonian users, on the one hand, express solidarity and sympathy with people suffering from HIV/AIDS. On the other hand, the emoticons and graphic signs are used to label and position people affected by HIV/AIDS. Thus, in the South African context social network sites have become an important space and means for communicating HIV/AIDS issues.

Computation in Non-Classical Foundations?

The Church-Turing Thesis is widely regarded as true, because of evidence that there is only one genuine notion of computation. By contrast, there are nowadays many different formal logics, and different corresponding foundational frameworks. Which ones can deliver a theory of computability? This question sets up a difficult challenge: the meanings of basic mathematical terms (like "set", "function", and "number") are not stable across frameworks. While it is easy to compare what different frameworks say, it is not so easy to compare what they mean. We argue for some minimal conditions that must be met if two frameworks are to be compared; if frameworks are radical enough, comparison becomes hopeless. Our aim is to clarify the dialectical situation in this bourgeoning area of research, shedding light on the nature of non-classical logic and the notion of computation alike.

"Monasterio de Sal" : Om elbasens introduktion i flamencovärlden via Carles Benavent

Flamenco guitarist Paco de Lucía, taking advantage of the ongoing cultural revolution in Spain during the seventies decided to break from tradition by shaping ”Nuevo Flamenco” through flamenco-jazz ensemble ”Paco de Lucía Sextet”. Within its repertoire, the first regular flamenco bass-line: ”Monasterio de Sal”. Electrical bassist Carles Benavent would have a key role in this development, a trait seldom found in academical works of musicology. The aim of the present thesis is to partially fill this void while shedding some light on the revolutionary contributions of Benavent. In order to do so, studying relevant literature, listening to phonograms comparatively, transcribing/analyzing ”Monasterio de Sal” and interviewing Mr. Benavent himself were used as main methods. The conclusion has been drawn that there was barely any electrical bass in flamenco before Benavent and that his work with de Lucía (and later others) would entirely reform the way electric bass was perceived from within and outside this genre of music. It is of no less interest to observe that Benavents main influences for this endeavor were the principal figures of contemporary jazz-bass (Jaco Pastorius) and flamenco-guitar (Paco de Lucía) respectively, infusing ”Monasterio de Sal”, with meaningful historical value.

Hodgkin's lymphoma cell lines express a fusion protein encoded by intergenically spliced mRNA for the multilectin receptor DEC-205 (CD205) and a novel C-type lectin receptor DCL-1

Classic Hodgkin's lymphoma (HL) tissue contains a small population of morphologically distinct malignant cells called Hodgkin and Reed-Sternberg (HRS) cells, associated with the development of HL. Using 3'-rapid amplification of cDNA ends ( RACE) we identified an alternative mRNA for the DEC-205 multilectin receptor in the HRS cell line L428. Sequence analysis revealed that the mRNA encodes a fusion protein between DEC-205 and a novel C-type lectin DCL-1. Although the 7.5-kb DEC-205 and 4.2-kb DCL-1 mRNA were expressed independently in myeloid and B lymphoid cell lines, the DEC-205/DCL-1 fusion mRNA (9.5 kb) predominated in the HRS cell lines ( L428, KM-H2, and HDLM-2). The DEC-205 and DCL-1 genes comprising 35 and 6 exons, respectively, are juxtaposed on chromosome band 2q24 and separated by only 5.4 kb. We determined the DCL-1 transcription initiation site within the intervening sequence by 5'-RACE, confirming that DCL-1 is an independent gene. Two DEC-205/DCL-1 fusion mRNA variants may result from cotranscription of DEC-205 and DCL-1, followed by splicing DEC-205 exon 35 or 34-35 along with DCL-1 exon 1. The resulting reading frames encode the DEC-205 ectodomain plus the DCL-1 ectodomain, the transmembrane, and the cytoplasmic domain. Using DCL-1 cytoplasmic domain-specific polyclonal and DEC-205 monoclonal antibodies for immunoprecipitation/Western blot analysis, we showed that the fusion mRNA is translated into a DEC-205/DCL-1 fusion protein, expressed in the HRS cell lines. These results imply an unusual transcriptional control mechanism in HRS cells, which cotranscribe an mRNA containing DEC-205 and DCL-1 prior to generating the intergenically spliced mRNA to produce a DEC-205/DCL-1 fusion protein.

Pollination ecology of the Australian cycad Lepidozamia peroffskyana (Zamiaceae)

Experiments carried out to investigate the reproductive ecology of the Australian cycad Lepidozamia peroffskyana (Regal, Bull. Soc. Imp. Nat. Mosc. 1857, 1: 184) revealed that this species is pollinated exclusively by host-specific Tranes weevils (Pascoe 1875). The weevils carry out their life cycle within the tissues of the male cones but also visit the female cones in large numbers. Female cones from which insects ( but not wind) were excluded had a pollination rate that was essentially zero. In contrast, female cones from which wind ( but not insects) were excluded had a pollination rate comparable with naturally pollinated cones. Assessment of Tranes weevil pollen load indicated that they are effective pollen-carriers. No other potential insect pollinators were observed on cones of L. peroffskyana. Sampling of airborne loads of cycad pollen indicated that wind-dispersed grains were not consistently recorded beyond a 2-m radius surrounding pollen-shedding male cones. The airborne load of cycad pollen in the vicinity of pollination-receptive female cones was minimal, and the spatial distribution of the coning population indicated that receptive female cones did not usually occur close enough to pollen-shedding male cones for airborne transfer of pollen to explain observed natural rates of seed set. These multiple lines of evidence suggest that wind-once considered the only pollination vector for cycads and other gymnosperms-plays only a minimal role in the pollination of L. peroffskyana, if any at all. The global diversity of insects associated with cycads suggests that some lineages of pollinating beetles may have been associated with cycad cones since Mesozoic times.

Human cytomegalovirus: clinical aspects, immune regulation, and emerging treatments

After initial infection, human cytomegalovirus remains in a persistent state with the host. Immunity against the virus controls replication, although intermitent viral shedding can still take place in the seropositive immunocompetent person. Replication of cytomegalovirus in the absence of an effective immune response is central to the pathogenesis of disease. Therefore, complications are primarily seen in individuals whose immune system is immature, or is suppressed by drug treatment or coinfection with other pathogens. Although our increasing knowledge of the host-virus relationship has lead to the development of new pharmacological strategies for cytomegalovirus-associated infections, these strategies all have limitations-eg, drug toxicities, development of resistance, poor oral bioavailability, and low potency. Immune-based therapies to complement pharmacological strategies for the successful treatment of virus-associated complications should be prospectively investigated.

The role of neurotransmission and the Chopper domain in p75 neurotrophin receptor death signaling

The role of p75 neurotrophin receptor (p75(NTR)) in mediating cell death is now well charaterized, however, it is only recently that details of the death signaling pathway have become clearer. This review focuses on the importance of the juxtamembrane Chopper domain region of p75(NTR) in this process. Evidence supporting the involvement of K+ efflux, the apoptosome (caspase-9, apoptosis activating factor-1, APAF-1, and Bcl-(xL)), caspase-3, c-jun kinase, and p53 in the p75(NTR) cell death pathway is discussed and regulatory roles for the p75(NTR) ectodomain and death domain are proposed. The role of synaptic activity is also discussed, in particular the importance of neutrotransmitter-activated K+ channels acting as the gatekeepers of cell survival decisions during development and in neurodegenerative conditions.

Long-term persistence of multi-drug-resistant Salmonella enterica serovar Newport in two dairy herds

Objective - To evaluate the association between maintaining joint hospital and maternity pens;and persistence of multi-drug-resistant (MDR) Salmonella enterica serovar Newport on 2 dairy farms. Design - Observational study. Sample Population - Feces and environmental samples from 2 dairy herds. Procedure - Herds were monitored for fecal shedding of S enterica Newport after outbreaks of clinical disease. Fecal and environmental samples were collected approximately monthly from pens housing sick cows and calving cows and from pens containing lactating cows. Cattle shedding the organism were tested serially on subsequent visits to determine carrier status. One farm was resampled after initiation of interventional procedures, including separation of hospital and maternity pens. Isolates were characterized via serotyping, determination of antimicrobial resistance phenotype, detection of the CMY-2 gene, and DNA fingerprinting. Results - The prevalence (32.4% and 33.3% on farms A and B, respectively) of isolating Salmonella from samples from joint hospital-maternity pens was significantly higher than the prevalence in samples from pens housing preparturient cows (0.8%, both farms) and postparturient cows on Farm B (8.8%). Multi-drug-resistant Salmonella Newport was isolated in high numbers from bedding material, feed refusals, lagoon slurry, and milk filters. One cow excreted the organism for 190 days. Interventional procedures yielded significant reductions in the prevalences of isolating the organism from fecal and environmental samples. Most isolates were of the C2 serogroup and were resistant to third-generation cephalosporins. Conclusions and Clinical Relevance - Management practices may be effective at reducing the persistence of MDR Salmonella spp in dairy herds, thus mitigating animal and public health risk.

Mechanisms of hematopoietic stem cell mobilization: When innate immunity assails the cells that make blood and bone

Mobilization is now used worldwide to collect large numbers of hematopoietic stem and progenitor cells (HSPCs) for transplantation. Although the first mobilizing agents were discovered largely by accident, discovery of more efficient mobilizing agents will require a better understanding of the molecular mechanisms responsible. During the past 5 years, a number of mechanisms have been identified, shedding new light on the dynamics of the hematopoietic system in vivo and on the intricate relationship between hematopoiesis, innate immunity, and bone. After briefly reviewing the mechanisms by which circulating HSPCs home into the bone marrow and what keeps them there, the current knowledge of mechanisms responsible for HSPC mobilization in response to hematopoietic growth factors such as granulocyte colony-stimulating factor, chemotherapy, chemokines, and polyanions will be discussed together with current strategies developed to further increase HSPC mobilization.

Solution structure and characterization of the LGR8 receptor binding surface of insulin-like peptide 3

Insulin-like peptide 3 (INSL3), a member of the relaxin peptide family, is produced in testicular Leydig cells and ovarian thecal cells. Gene knock-out experiments have identified a key biological role in initiating testes descent during fetal development. Additionally, INSL3 has an important function in mediating male and female germ cell function. These actions are elicited via its recently identified receptor, LGR8, a member of the leucine-rich repeat-containing G-protein- coupled receptor family. To identify the structural features that are responsible for the interaction of INSL3 with its receptor, its solution structure was determined by NMR spectroscopy together with in vitro assays of a series of B-chain alanine-substituted analogs. Synthetic human INSL3 was found to adopt a characteristic relaxin/ insulin-like fold in solution but is a highly dynamic molecule. The four termini of this two-chain peptide are disordered, and additional conformational exchange is evident in the molecular core. Alanine-substituted analogs were used to identify the key residues of INSL3 that are responsible for the interaction with the ectodomain of LGR8. These include Arg(B16) and Val(B19), with His(B12) and Arg(B20) playing a secondary role, as evident from the synergistic effect on the activity in double and triple mutants involving these residues. Together, these amino acids combine with the previously identified critical residue, Trp(B27), to form the receptor binding surface. The current results provide clear direction for the design of novel specific agonists and antagonists of this receptor.

theta-defensins prevent HIV-1 Env-mediated fusion by binding gp41 and blocking 6-helix bundle formation

Retrocyclin-1, a 0-defensin, protects target cells from human immunodeficiency virus, type 1 (HIV-1) by preventing viral entry. To delineate its mechanism, we conducted fusion assays between susceptible target cells and effector cells that expressed HIV-1 Env. Retrocyclin-1 (4 mu M) completely blocked fusion mediated by HIV-1 Envs that used CXCR4 or CCR5 but had little effect on cell fusion mediated by HIV-2 and simian immunodeficiency virus Envs. Retrocyclin-1 inhibited HIV-1 Env-mediated fusion without impairing the lateral mobility of CD4, and it inhibited the fusion of CD4-deficient cells with cells bearing CD4-independent HIV-1 Env. Thus, it could act without cross-linking membrane proteins or inhibiting gp120-CD4 interactions. Retrocyclin-1 acted late in the HIV-1 Env fusion cascade but prior to 6-helix bundle formation. Surface plasmon resonance experiments revealed that retrocyclin bound the ectodomain of gp41 with high affinity in a glycan-independent manner and that it bound selectively to the gp41 C-terminal heptad repeat. Native-PAGE, enzyme-linked immunosorbent assay, and CD spectroscopic analyses all revealed that retrocyclin-1 prevented 6-helix bundle formation. This mode of action, although novel for an innate effector molecule, resembles the mechanism of peptidic entry inhibitors based on portions of the gp41 sequence.
