Unemployment, labor costs, and recessions: implications for the inflation outlook

Economists have been arguing about the connection between unemployment and infl ation for decades. Critics claim that the connection is unreliable and leads policymakers astray, while others argue that the relationship is useful for forecasting. We examine the more direct connections between elevated unemployment levels and the rate of increase in wage and labor costs, more generally. We fi nd that wage and labor cost growth has declined markedly following recent recessions. It has again declined sharply in the most recent recession. We also fi nd that compensation typically remains subdued during the initial phases of recent recoveries. This is again the case in the current recovery, making labor costs a significant restraining force on inflation going forward.Recessions ; Inflation (Finance) ; Inflation targeting

From green to ethical consumers: What should you change in your advertisement to motivate them to buy ethical products?

This article introduces a two-dimensional model that aims to capture the complexity of motives of contemporary ethical consumers. The framework identifies four broad motivations for ethical consumption: Self-actualization, Hedonic, Conformity and Self-Orientation. To illustrate how the framework may be used, we present the results of two exploratory studies; the first examining the motivations of self-identifying ethical consumers (173 consumers from 27 nationalities), and the second analysing the primary motivating message of a set of 23 advertisements for ethical products from eight different countries. Our results indicate that while all four categories of motivation are salient to consumers, advertisers in our sample tended to focus their message on only one category of motivations (selfactualization)

From Green to Ethical Consumers: What Really Motivates Consumers to Buy Ethical Products?

Ethical consumers have evolved from boycotting to consuming and ethical consumption has attracted much attention from marketing researchers recently. Several studies have been conducted to understand what motivates consumers to buy certain ethical products such as fair trade, eco-friendly or animal-friendly. While a number of disparate, and primarily descriptive, studies have identified motivations of ethical consumers towards an array of different products and in a variety of contexts, researchers are yet to develop a more generalizable framework for understanding ethical consumption motivations. In this paper, we present a framework of four universal motivations to explain why consumers buy ethical products

A serological investigation of caseous lymphadenitis in four flocks of sheep

A double antibody sandwich ELISA developed by ID-DLO, Lelystad to detect Corynebocterium pseudotuberculosis infection was used on 329 sheep from four pedigree Suffolk flocks in which clinical cases of caseous lymphadenitis (CLA) had occurred. At subsequent necropsy, typical CLA lesions were seen in 133 sheep, and the diagnosis was confirmed on culture. Lesions were most commonly seen in lungs (n = 46), parotid lymph nodes (n = 44), prescapular lymph nodes (n = 38) and mediastinal lymph nodes (n = 31). The sensitivity of the ELISA test for detecting culture-positive sheep was 0.88, while the specificity of the test was 0.55. The antibody ELISA detected 87.5 per cent of sheep that had CLA lesions restricted to internal organs only. It was concluded that the ELISA test has a valuable role in detecting sheep with both clinical and subclinical CLA

Cyclin D1 and p16 expression in recurrent nasopharyngeal carcinoma

Abstract Background Cyclin D1 and p16 are involved in the regulation of G1 checkpoint and may play an important role in the tumorigenesis of nasopharyngeal carcinoma (NPC). Previous studies have examined the level of expression of cyclin D1 and p16 in primary untreated NPC but no such information is available for recurrent NPC. We set out in this study to examine the expression level of cyclin D1 and p16 in recurrent NPC that have failed previous treatment with radiation +/- chemotherapy. Patients and methods A total of 42 patients underwent salvage nasopharyngectomy from 1984 to 2001 for recurrent NPC after treatment failure with radiation +/- chemotherapy. Twenty-seven pathologic specimens were available for immunohistochemical study using antibodies against cyclin D1 and p16. Results Positive expression of cyclin D1 was observed in 7 of 27 recurrent NPC specimens (26%) while positive p16 expression was seen in only 1 of 27 recurrent NPC (4%). Conclusion While the level of expression of cyclin D1 in recurrent NPC was similar to that of previously untreated head and neck cancer, the level of p16 expression in recurrent NPC samples was much lower than that reported for previously untreated cancer. The finding that almost all (96%) of the recurrent NPC lack expression of p16 suggested that loss of p16 may confer a survival advantage by making cancer cells more resistant to conventional treatment with radiation +/- chemotherapy. Further research is warranted to investigate the clinical use of p16 both as a prognostic marker and as a potential therapeutic target

Automorphisms of Real 4 Dimensional Lie Algebras and the Invariant Characterization of Homogeneous 4-Spaces

The automorphisms of all 4-dimensional, real Lie Algebras are presented in a comprehensive way. Their action on the space of $4\times 4$, real, symmetric and positive definite, matrices, defines equivalence classes which are used for the invariant characterization of the 4-dimensional homogeneous spaces which possess an invariant basis.Comment: LaTeX2e, 23 pages, 2 Tables.

A constraint on antigravity of antimatter from precision spectroscopy of simple atoms

Consideration of antigravity for antiparticles is an attractive target for various experimental projects. There are a number of theoretical arguments against it but it is not quite clear what kind of experimental data and theoretical suggestions are involved. In this paper we present straightforward arguments against a possibility of antigravity based on a few simple theoretical suggestions and some experimental data. The data are: astrophysical data on rotation of the Solar System in respect to the center of our galaxy and precision spectroscopy data on hydrogen and positronium. The theoretical suggestions for the case of absence of the gravitational field are: equality of electron and positron mass and equality of proton and positron charge. We also assume that QED is correct at the level of accuracy where it is clearly confirmed experimentally

Control of primary productivity and the significance of photosynthetic bacteria in a meromictic kettle lake.

During 1986 planktonic primary production and controlling factors were investigated in a small (A0 = 11.8 · 103 m2, Zmax = 11.5 m) meromictic kettle lake (Mittlerer Buchensee). Annual phytoplankton productivity was estimated to ca 120 gC · m–2 · a–1 (1,42 tC · lake–1 · a–1). The marked thermal stratification of the lake led to irregular vertical distributions of chlorophylla concentrations (Chla) and, to a minor extent, of photosynthesis (Az). Between the depths of 0 to 6 m low Chla concentrations (< 7 mg · m–3) and comparatively high background light attenuation (kw = 0,525 m–1, 77% of total attenuation due to gelbstoff and abioseston) was found. As a consequence, light absorption by algae was low (mean value 17,4%) and self-shading was absent. Because of the small seasonal variation of Chla concentrations, no significant correlation between Chla and areal photosynthesis (A) was observed. Only in early summer (June–July) biomass appears to influence the vertical distribution of photosynthesis on a bigger scale. Around 8 m depth, low-light adapted algae and phototrophic bacteria formed dense layers. Due to low ambient irradiances, the contribution of these organisms to total primary productivity was small. Primary production and incident irradiance were significantly correlated with each other (r2 = 0.68). Although the maximum assimilation number (Popt) showed a clear dependence upon water temperature (Q10 = 2.31), the latter was of minor importance to areal photosynthesis
