An Examination of Volunteer Motivation in Credit Unions: Informing Volunteer Resource Management

Volunteer recruitment and retention is a problem that most credit unions experience. Research suggests that knowledge of volunteer motivation can inform volunteer management strategies. This paper uses a survey approach to determine whether current volunteers in credit unions in Northern Ireland are more motivated by the actual act of volunteering, by the output from the volunteering activity (including altruism) or because the volunteering activity increases their human capital value. Altruistic reasons are found to be the most influential, with the act of volunteering also scoring highly. This knowledge should inform volunteer recruitment programmes and internal appraisal processes as management can reinforce messages that provide positive feedback to volunteers on the social benefits being achieved by the credit union. This will further motivate current volunteers, ensuring retention. When motivation was analyzed by volunteer characteristics we found that older volunteers, retired volunteers and volunteers who are less educated are more motivated in their role. There was little evidence that individuals volunteer to improve their human capital worth.

IMMUNOCYTOCHEMICAL AND RADIOIMMUNOMETRICAL DEMONSTRATION OF SEROTONIN-IMMUNOREACTIVITIES AND NEUROPEPTIDE-IMMUNOREACTIVITIES IN THE ADULT-RAT TAPEWORM, HYMENOLEPIS-DIMINUTA (CESTODA, CYCLOPHYLLIDEA)

Standard indirect immunocytochemical techniques have been interfaced with confocal scanning laser microscopy (for whole-mount preparations) and epifluorescence microscopy (for cryosections) to investigate the occurrence and distribution of serotoninergic and peptidergic nerve elements in adult H. diminuta. Serotonin (5-HT)-immunoreactivity (IR) was widespread throughout the worm, occurring in the paired cerebral ganglia, transverse commissure, the 10 longitudinal nerve cords and in a plethora of small nerve fibres of the peripheral nervous system. An abundance of serotoninergic nerve cell bodies was found in association with the lateral nerve cords. The genital atrium and accessory reproductive ducts were richly innervated with serotoninergic nerve fibres. Thirty-five antisera to 20 vertebrate regulatory peptides and 1 invertebrate peptide (FMRFamide) were used to screen the worm for neuropeptide IR. Immunostaining was obtained with antisera raised to pancreatic polypeptide (PP), peptide YY (PYY), neuropeptide Y (NPY), substance P (SP), peptide histidine isoleucine (PHI), xenopsin (XP) and FMRFamide. The most extensive pattern of IR occurred with antisera to PP and PYY, IR being evident in the cerebral ganglia, transverse commissure, longitudinal nerve cords and in small nerve fibres that ramified throughout the parenchyma. A series of bipolar nerve cell bodies between the median nerve cords displayed PP/PYY-IR. The distribution of FMRFamide-IR was reminiscent of the PP/PYY pattern but was less extensive. Comparison of the serotoninergic and peptidergic nervous systems has revealed general similarities and some distinct differences, especially with regard to the distribution of immunoreactive nerve cell bodies. Quantitative data are presented on the levels of PP-, SP-, PHI-, and gastrin-releasing peptide (GRP)-immunoreactivities demonstrable in acid-alcohol extracts of whole worms. The highest level of peptide IR determined was recorded for PP.

Catalysing open innovation through publicly funded R&D: A Comparison of University and Company-based research centres

Public funding of university and company-based R&D centres of excellence is widespread both in core and more peripheral regions. What is less well-known is whether these R&D centres can catalyse multi-directional, multi-actor and iterative innovation. Based on data from a real-time monitoring study, this article explores the development of 18 R&D centres’ external connections. University-based R&D centres establish more new connections than company-based centres and are more likely to be interacting with small or micro-firms. However, there is a general bias towards links with larger firms; micro, small and medium-sized enterprises also are less likely to be involved in collaborative R&D with research centres than other types of relationships. The results suggest the potential for R&D centres to act as a catalyst for open innovation but emphasise the need to ensure that the focus of the R&D being conducted is relevant to the needs of smaller firms.

Effects of Charge Location on the Absorptions and Lifetimes of Protonated Tyrosine Peptides in Vacuo

Nearby charges affect the electronic energy levels of chromophores, with the extent of the effect being determined by the magnitude of the charge and degree of charge-chromophore separation. The molecular configuration dictates the charge chromophore distance. Hence, in this study, we aim to assess how the location of the charge influences the absorption of a set of model protonated and diprotonated peptide ions, and whether spectral differences are large enough to be identified. The studied ions were the dipeptide YK, the tripeptide KYK (Y = tyrosine; K = lysine) and their complexes with 18-crown-6-ether (CE). The CE targets the ammonium group by forming internal ionic hydrogen bonds and limits the folding of the peptide. In the tripeptide, the distance between the chromophore and the backbone ammonium is enlarged relative to that in the dipeptide. Experiments were performed in an electrostatic ion storage ring using a tunable laser system, and action spectra based on lifetime measurements were obtained in the range from 210 to 310 nm. The spectra are all quite similar though there seems to be some changes in the absorption band between 210 and 250 nm, while in the lower energy band all ions had a maximum absorption at similar to 275 nm. Lifetimes after photoexcitation were found to shorten upon protonation and lengthen upon CE complexation, in accordance with the increased number of degrees of freedom and an increase in activation energies for dissociation as the mobile proton model is no longer operative.

‘Proficiscere, anima Christiana’: Gerontius and German mysticism

The popularity in Britain of Elgar's _The Dream of Gerontius_ was triggered by the successful reception of the work in Germany in December 1901 and May 1902. By examining some of the writings on Elgar by German critics in this period, I explain that what may have particularly have appealed to German audiences was the composer's engagement with mysticism, something that as well as being a distinct strand of German theology since medieval times had acquired a new popularity among German artists in a number of fields as part of a reaction to the materialism of Wilhelmine Germany. Through a reading of the work that takes into account both its Catholic theology and ideas of mysticism more generally, I propose that the two Parts of the work should be conceived as taking place simultaneously, rather than successively, and that the work is thus best understood as belonging to the genre of epic rather than drama. ©2013 The Royal Musical Association

Identification, expression, and DNA sequence of the GDP-mannose biosynthesis genes encoded by the O7 rfb gene cluster of strain VW187 (Escherichia coli O7:K1)

The O7-specific lipopolysaccharide (LPS) in strains of Escherichia coli consists of a repeating unit made of galactose, mannose, rhamnose, 4-acetamido-2,6-dideoxyglucose, and N-acetylglucosamine. We have recently cloned and characterized genetically the O7-specific LPS biosynthesis region (rfbEcO7) of the E. coli O7:K1 strain VW187 (C. L. Marolda, J. Welsh, L. Dafoe, and M. A. Valvano, J. Bacteriol. 172:3590-3599, 1990). In this study, we localized the gnd gene encoding gluconate-6-phosphate dehydrogenase at one end of the rfbEcO7 gene cluster and sequenced that end of the cluster. Three open reading frames (ORF) encoding polypeptides of 275, 464, and 453 amino acids were identified upstream of gndEcO7, all transcribed toward the gnd gene. ORF275 had 45% similarity at the protein level with ORF16.5, which occupies a similar position in the Salmonella enterica LT2 rfb region, and presumably encodes a nucleotide sugar transferase. The polypeptides encoded by ORFs 464 and 453 were expressed under the control of the ptac promoter and visualized in Coomassie blue-stained sodium dodecyl sulfate-polyacrylamide gels and by maxicell analysis. ORF464 expressed GDP-mannose pyrophosphorylase and ORF453 encoded a phosphomannomutase, the enzymes for the biosynthesis pathway of GDP-mannose, one of the nucleotide sugar precursors for the formation of the O7 repeating unit. They were designated rfbMEcO7 and rfbKEcO7, respectively. The RfbMEcO7 polypeptide was homologous to the corresponding protein in S. enterica LT2, XanB of Xanthomonas campestris, and AlgA of Pseudomonas aeruginosa, all GDP-mannose pyrophosphorylases. RfbKEcO7 was very similar to CpsG of S. enterica LT2, an enzyme presumably involved in the biosynthesis of the capsular polysaccharide colanic acid, but quite different from the corresponding RfbK protein of S. enterica LT2.

Segregation Preferences of Urban and Rural 16-year-olds in Northern Ireland

Sectarian violence in the Northern Ireland is often perceived to be mostly confined to cities. The aim of this paper is to explore statistically what factors contribute to segregation preferences among young people living in rural and urban areas, using the 2005–2009 Young Life and Times (YLT) survey – an annual attitudes survey of 16-year-olds. The findings show that religious and national identities are the strongest predictors of segregation preferences among 16-year-olds, regardless of where they live and what background they have. Those living in rural areas of Northern Ireland are more supportive of residential, workplace and educational segregation than those living in more urban areas. This research highlights the need for government policy to take rurality into account. Nevertheless, some variables significantly determine segregation preferences regardless of where respondents live, such as attendance of segregated schools, being female, or strength of national and religious identity. Consequently, policy initiatives should continue to address the effect of segregation, especially in relation to education, and future research exploring social class and gender is recommended. In conclusion, the perception of the violent ‘urban spaces’ and the ‘peaceful countryside’ has to be challenged.
