Approach-avoidance of facial affect is moderated by the presence of an observer-irrelevant trigger

This study examined whether approach-avoidance related behaviour elicited by facial affect is moderated by the presence of an observer-irrelevant trigger that may influence the observer's attributions of the actor's emotion. Participants were shown happy, disgusted, and neutral facial expressions. Half of these were presented with a plausible trigger of the expression (a drink). Approach-avoidance related behaviour was indexed explicitly through a questionnaire (measuring intentions) and implicitly through a manikin version of the affective Simon task (measuring automatic behavioural tendencies). In the absence of an observer-irrelevant trigger, participants expressed the intention to avoid disgusted and approach happy facial expressions. Participants also showed a stronger approach tendency towards happy than towards disgusted facial expressions. The presence of the observer-irrelevant trigger had a moderating effect, decreasing the intention to approach happy and to avoid disgusted expressions. The trigger had no moderating effect on the approach-avoidance tendencies. Thus the influence of an observer-irrelevant trigger appears to reflect more of a controlled than automatic process

FISH mapping and molecular organization of the major repetitive sequences of tomato

This paper presents a bird's-eye view of the major repeats and chromatin types of tomato. Using fluorescence in-situ hybridization (FISH) with Cot-1, Cot-10 and Cot-100 DNA as probes we mapped repetitive sequences of different complexity on pachytene complements. Cot-100 was found to cover all heterochromatin regions, and could be used to identify repeat-rich clones in BAC filter hybridization. Next we established the chromosomal locations of the tandem and dispersed repeats with respect to euchromatin, nucleolar organizer regions (NORs), heterochromatin, and centromeres. The tomato genomic repeats TGRII and TGRIII appeared to be major components of the pericentromeres, whereas the newly discovered TGRIV repeat was found mainly in the structural centromeres. The highly methylated NOR of chromosome 2 is rich in [GACA](4), a microsatellite that also forms part of the pericentromeres, together with [GA](8), [GATA](4) and Ty1-copia. Based on the morphology of pachytene chromosomes and the distribution of repeats studied so far, we now propose six different chromatin classes for tomato: (1) euchromatin, (2) chromomeres, (3) distal heterochromatin and interstitial heterochromatic knobs, (4) pericentromere heterochromatin, (5) functional centromere heterochromatin and (6) nucleolar organizer regio

The Impact Of Economic Factors On The Relationships Between Psychological Contract Breach And Job Behaviors: A Meta-Analysis

Purpose The purpose of this paper is to explore the macro-economic factors that may moderate the psychological contract breach and work outcome relationship. Design/methodology/ approach This study conducted a meta-analysis based-on data from 95 studies. Findings The study revealed that the inflation rate and the unemployment rate of a country moderated the association among employee psychological contract breach, job performance and turnover. Research limitations/ implications The availability of more detailed macro-economic data against the PCB and outcome relationship for other countries and studies examining the impact of micro-economic data for psychological contract breach and outcome relationship would provide a better understanding of the context. Social implications Employment policies to capture the impact of macro-economic circumstances as discussed. Originality/value The paper contributes to understanding the impact of macro-economic indicators on the relationships among psychological contract breach, job performance and turnover

In-dept sequence analysis of the tomato chromosome 12 centromeric region: indentification of a large CAA block and characterization of pericentromere retrotranposons

We sequenced a continuous 326-kb DNA stretch of a microscopically defined centromeric region of tomato chromosome 12. A total of 84% of the sequence (270 kb) was composed of a nested complex of repeat sequences including 27 retrotransposons, two transposable elements, three MITEs, two terminal repeat retrotransposons in miniature (TRIMs), ten unclassified repeats and three chloroplast DNA insertions. The retrotransposons were grouped into three families of Ty3-Gypsy type long terminal repeat (LTR) retrotransposons (PCRT1¿PCRT3) and one LINE-like retrotransposon (PCRT4). High-resolution fluorescence in situ hybridization analyses on pachytene complements revealed that PCRT1a occurs on the pericentromere heterochromatin blocks. PCRT1 was the prevalent retrotransposon family occupying more than 60% of the 326-kb sequence with 19 members grouped into eight subfamilies (PCRT1a¿PCRT1h) based on LTR sequence. The PCRT1a subfamily is a rapidly amplified element occupying tens of megabases. The other PCRT1 subfamilies (PCRT1b¿PCRT1h) were highly degenerated and interrupted by insertions of other elements. The PCRT1 family shows identity with a previously identified tomato-specific repeat TGR2 and a CENP-B like sequence. A second previously described genomic repeat, TGR3, was identified as a part of the LTR sequence of an Athila-like PCRT2 element of which four copies were found in the 326-kb stretch. A large block of trinucleotide microsatellite (CAA)n occupies the centromere and large portions of the flanking pericentromere heterochromatin blocks of chromosome 12 and most of the other chromosomes. Five putative genes in the remaining 14% of the centromere region were identified, of which one is similar to a transcription regulator (ToCPL1) and a candidate jointless-2 gene. The sequence data from this study have been submitted to GenBank under accession no. AY85039

Toward closing rice telomere gaps: mapping and sequence characterization of rice subtelomere regions.

Despite the collective efforts of the international community to sequence the complete rice genome, telomeric regions of most chromosome arms remain uncharacterized. In this report we present sequence data from subtelomere regions obtained by analyzing telomeric clones from two 8.8 × genome equivalent 10-kb libraries derived from partial restriction digestion with HaeIII or Sau3AI (OSJNPb HaeIII and OSJNPc Sau3AI). Seven telomere clones were identified and contain 25¿100 copies of the telomere repeat (CCCTAAA)n on one end and unique sequences on the opposite end. Polymorphic sequence-tagged site markers from five clones and one additional PCR product were genetically mapped on the ends of chromosome arms 2S, 5L, 10S, 10L, 7L, and 7S. We found distinct chromosome-specific telomere-associated tandem repeats (TATR) on chromosome 7 (TATR7) and on the short arm of chromosome 10 (TATR10s) that showed no significant homology to any International Rice Genome Sequencing Project (IRGSP) genomic sequence. The TATR7, a degenerate tandem repeat which is interrupted by transposable elements, appeared on both ends of chromosome 7. The TATR10s was found to contain an inverted array of three tandem repeats displaying an interesting secondary folding pattern that resembles a telomere loop (t-loop) and which may be involved in a protective function against chromosomal end degradatio

Association of Adherence to a Healthy Diet with Cognitive Decline in European and American Older Adults

Aim: To examine the association between a healthy diet, assessed by the Healthy Diet Indicator (HDI), and cognitive decline in older adults. Methods: Data from 21,837 participants aged ≥ 55 years from 3 cohorts (Survey in Europe on Nutrition and the Elderly, a Concerted Action[SENECA], Rotterdam Study [RS], Nurses’ Health Study [NHS]) were analyzed. HDI scores were based on intakes of saturated fatty acids, polyunsaturated fatty acids, mono- and disaccharides, protein, cholesterol, fruits and vegetables, and fiber. The Telephone Interview for Cognitive Status in NHS and Mini-Mental State Examination in RS and SENECA were used to assess cognitive function from multiple repeated measures. Using multivariable-adjusted, mixed linear regression, mean differences in annual rates of cognitive decline by HDI quintiles were estimated. Results: Multivariable-adjusted differences in rates in the highest versus the lowest HDI quintile were 0.01 (95% CI –0.01, 0.02) in NHS, 0.00 (95% CI –0.02, 0.01) in RS, and 0.00 (95% CI –0.05, 0.05) in SENECA with a pooled estimate of 0.00 (95% CI –0.01, 0.01), I 2 = 0%. Conclusions: A higher HDI score was not related to reduced rates of cognitive decline in European and American older adults

Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory

Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-runner experiments. Our results do not support previous findings of localized excesses in the AGASA and SUGAR data. We set an upper bound on a point-like flux of cosmic rays arriving from the Galactic Centre which excludes several scenarios predicting sources of EeV neutrons from Sagittarius $A$. Also the events detected simultaneously by the surface and fluorescence detectors (the `hybrid' data set), which have better pointing accuracy but are less numerous than those of the surface array alone, do not show any significant localized excess from this direction.Comment: Matches published versio
