Holding parties responsible at election time: Multi-level, multi-party government and electoral accountability

This paper highlights the crucial role played by party-specific responsibility attributions in performance-based voting. Three models of electoral accountability, which make distinct assumptions regarding citizens' ability to attribute responsibility to distinct governing parties, are tested in the challenging Northern Ireland context - an exemplar case of multi-level multi-party government in which expectations of performance based voting are low. The paper demonstrates the operation of party-attribution based electoral accountability, using data from the 2011 Northern Ireland Assembly Election Study. However, the findings are asymmetric: accountability operates in the Protestant/unionist bloc but not in the Catholic/nationalist bloc. This asymmetry may be explained by the absence of clear ethno-national ideological distinctions between the unionist parties (hence providing political space for performance based accountability to operate) but the continued relevance in the nationalist bloc of ethno-national difference (which limits the scope for performance politics). The implications of the findings for our understanding of the role of party-specific responsibility attribution in performance based models of voting, and for our evaluation of the quality of democracy in post-conflict consociational polities, are discussed. 

Does antenatal education prepare fathers for their role as birth partners and for parenthood?

A systematic review of the literature was undertaken to explore fathers' opinions and views on antenatal education and its effectiveness in preparing them for their role as birth partners and for parenthood. The findings are categorised under four key themes: outnumbered, excluded, anxious and uncertain, and preparedness. While research suggests that most fathers want to support their partners and be involved in the pregnancy, labour and birth of their baby, they are less likely to attend antenatal classes than women. While fathers who attend antenatal education classes value them, their experiences are not always as positive or helpful in preparing them for their role as birth partners or in parenthood. It was highlighted that men are more likely to feel unprepared when complications at birth arise. A common finding was that men would welcome the opportunity to focus on their individual needs.

Slug-dependent upregulation of L1CAM is responsible for the increased invasion potential of pancreatic cancer cells following long-term 5-FU treatment

BACKGROUND: Pancreatic adenocarcinoma is a lethal disease with 5-year survival of less than 5%. 5-fluorouracil (5-FU) is a principal first-line therapy, but treatment only extends survival modestly and is seldom curative. Drug resistance and disease recurrence is typical and there is a pressing need to overcome this. To investigate acquired 5-FU resistance in pancreatic adenocarcinoma, we established chemoresistant monoclonal cell lines from the Panc 03.27 cell line by long-term exposure to increasing doses of 5-FU.

RESULTS: 5-FU-resistant cell lines exhibited increased expression of markers associated with multidrug resistance explaining their reduced sensitivity to 5-FU. In addition, 5-FU-resistant cell lines showed alterations typical for an epithelial-to-mesenchymal transition (EMT), including upregulation of mesenchymal markers and increased invasiveness. Microarray analysis revealed the L1CAM pathway as one of the most upregulated pathways in the chemoresistant clones, and a significant upregulation of L1CAM was seen on the RNA and protein level. In pancreatic cancer, expression of L1CAM is associated with a chemoresistant and migratory phenotype. Using esiRNA targeting L1CAM, or by blocking the extracellular part of L1CAM with antibodies, we show that the increased invasiveness observed in the chemoresistant cells functionally depends on L1CAM. Using esiRNA targeting β-catenin and/or Slug, we demonstrate that in the chemoresistant cell lines, L1CAM expression depends on Slug rather than β-catenin.

CONCLUSION: Our findings establish Slug-induced L1CAM expression as a mediator of a chemoresistant and migratory phenotype in pancreatic adenocarcinoma cells.

Parenthood and Open Adoption: an Interpretative Phenomenological Analysis

This book explores what it is like to be involved in contemporary open adoption, characterised by varying forms of contact with birth relatives, from an adoptive parent point of view.

The author’s fine-grained interpretative phenomenological analysis of adopters’ accounts reveals the complexity of kinship for those whose most significant relationships are made, unmade and permanently altered through adoption. MacDonald distinctively connects adoption to wider sociological theories of relatedness and personal life, and focuses on domestic non-kin adoption of children from state care, including compulsory adoption. The book also addresses current child welfare concerns, and suggestions are made for adoption practice. The book will be of interest to scholars and students with an interest in adoption, social work, child welfare, foster care, family and sociology.

Facilitating a culture of responsible and effective sharing of cancer genome data

Rapid and affordable tumor molecular profiling has led to an explosion of clinical and genomic data poised to enhance the diagnosis, prognostication and treatment of cancer. A critical point has now been reached at which the analysis and storage of annotated clinical and genomic information in unconnected silos will stall the advancement of precision cancer care. Information systems must be harmonized to overcome the multiple technical and logistical barriers to data sharing. Against this backdrop, the Global Alliance for Genomic Health (GA4GH) was established in 2013 to create a common framework that enables responsible, voluntary and secure sharing of clinical and genomic data. This Perspective from the GA4GH Clinical Working Group Cancer Task Team highlights the data-aggregation challenges faced by the field, suggests potential collaborative solutions and describes how GA4GH can catalyze a harmonized data-sharing culture.

An alteration in the levels of populations of CD4+ Treg is in part responsible for altered cytokine production by cells of aged mice which follows injection with a fetal liver extract.

We have shown previously that a fetal sheep liver extract (FSLE) containing significant quantities of fetal ovine gamma globin chain (Hbgamma) and LPS injected into aged (>20 months) mice could reverse the altered polarization (increased IL-4 and IL-10 with decreased IL-2 and IFNgamma) in cytokine production seen from ConA stimulated lymphoid cells of those mice. The mechanism(s) behind this change in cytokine production were not previously investigated. We report below that aged mice show a >60% decline in numbers and suppressive function of both CD4(+)CD25(+)Foxp3(+) Treg and so-called Tr3 (CD4(+)TGFbeta(+)), and that their number/function is restored to levels seen in control (8-week-old) mice by FSLE. In addition, on a per cell basis, CD4(+)CD25(-)Treg from aged mice were >4-fold more effective in suppression of proliferation and IL-2 production from ConA-activated lymphoid cells of a pool of CD4(+)CD25(-)T cells from 8-week-old mice than similar cells from young animals, and this suppression by CD25(-)T cells was also ameliorated following FSLE treatment. Infusion of anti-TGFbeta and anti-IL-10 antibodies in vivo altered Treg development following FSLE treatment, and attenuated FSLE-induced alterations in cytokine production profiles.

Temperature-induced sex reversal is not responsible for sex-ratio distortions in grayling Thymallus thymallus or brown trout Salmo trutta.

On the basis of the experiments carried out over various years, it was concluded that (1) grayling Thymallus thymallus and brown trout Salmo trutta are resistant to temperature-induced sex reversal at ecologically relevant temperatures, (2) environmental sex reversal is unlikely to cause the persistent sex ratio distortion observed in at least one of the study populations and (3) sex-specific tolerance of temperature-related stress may be the cause of distorted sex ratios in populations of T. thymallus or S. trutta.

National energy policies of the Federal Republic of Germany and Canada in the 1970s and 1980s: are economic and/or environmental concerns responsible for change?

The thesis presents a comparison of the national energy policies of the Federal Republic of Germany and Canada from 1973 until the late 1980s. The purpose of this paper is to analyze whether economic and/or environmental concerns were responsible for changes in the· West-German and Canadian national energy policies. Furthermore, the feasibility of implementing a soft energy path in West-Germany and Canada is examined. For better comprehension of the policy-making process and implemented changes in the national energy policies of the two states, the West-German and Canadian parliamentary systems and the political cultures were compared. For the analysis, several events with international impact were taken as guidelines. Furthermore, based on statistical data, the West-German and Canadian energy production and consumption were analyzed. With reference to these results the degree of the de facto changes in the national energy policies were analyzed. In addition, the thesis discusses the possibilities which a soft energy path offers to both national governments to renounce themselves from the dependencies on a few energy resources. The thesis reveals that changes in the West-German and Canadian national energy policies, in their energy production and consumption are correlated to various world events. In particular, governmental reponses security of energy supply by the two international oil crises of 1973 and 1979/1980 demonstrate that changes in the West-German and Canadian national energy policies were implemented in reaction to economic concerns than environmental ones. With the policies "away from oil" and "off oil", the West-German and Canadian government implemented the i i substitution of oil through various diverse energy supply resources. However, energy savings concepts and policies were initiated through the first oil crisis in 1973. The world recessions in 1975 and 1982 had no 'profound impacts on the agenda of West-German and Canadian energy policies. As a consequence of the stagnation or the negative growth of the world economic market, changes in their energy production and consumption can be perceived. However, the West-German and Canadian energy production and consumption intensified with the augmentation of the world economy. During the period of study, environmental concerns were taken into account in the energy policy agendas of the Federal Republic of Germany and Canada but they were not of primary concern. wi thin the decade of. the 1980s notably more environmental considerations were taken into account in the energy policies of the two states. The two nuclear reactor accidents in 1979 and 1986 sharpened to various degrees West-German and Canadian public discourse of present energy supply mix and attitude towards energy production and consumption. The statistical data reflects yet no changes in the energy policies in regard to the position of nuclear power. However, in the next several years possible changes can be observed through statistical data, because the planning, the construction and possible phase out of nuclear power requires several years. Finally, the thesis reveals that the implementation of a soft energy path requires profound changes in the consumer behaviour. As several studies indicate, a soft energy path is technological and economically feasible for the Federal Republic of Germany and Canada, its implementation remains to be a political decision.

The γ-tocopherol-like family of N-methyltransferases: A taxonomically clustered gene family encoding enzymes responsible for N-methylation of monoterpene indole alkaloids

The plant family Apocynaceae accumulates thousands of monoterpene indole alkaloids (MIAs) which originate, biosynthetically, from the common secoiridoid intermediate, strictosidine, that is formed from the condensation of tryptophan and secologanin molecules. MIAs demonstrate remarkable structural diversity and have pharmaceutically valuable biological activities. For example; a subunit of the potent anti-neoplastic molecules vincristine and vinblastine is the aspidosperma alkaloid, vindoline. Vindoline accumulates to trace levels under natural conditions. Research programs have determined that there is significant developmental and light regulation involved in the biosynthesis of this MIA. Furthermore, the biosynthetic pathway leading to vindoline is split among at least five independent cell types. Little is known of how intermediates are shuttled between these cell types. The late stage events in vindoline biosynthesis involve six enzymatic steps from tabersonine. The fourth biochemical step, in this pathway, is an indole N-methylation performed by a recently identified N-methyltransfearse (NMT). For almost twenty years the gene encoding this NMT had eluded discovery; however, in 2010 Liscombe et al. reported the identification of a γ-tocopherol C-methyltransferase homologue capable of indole N-methylating 2,3-dihydrotabersonine and Virus Induced Gene Silencing (VIGS) suppression of the messenger has since proven its involvement in vindoline biosynthesis. Recent large scale sequencing initiatives, performed on non-model medicinal plant transcriptomes, has permitted identification of candidate genes, presumably involved, in MIA biosynthesis never seen before in plant specialized metabolism research. Probing the transcriptome assemblies of Catharanthus roseus (L.)G.Don, Vinca minor L., Rauwolfia serpentine (L.)Benth ex Kurz, Tabernaemontana elegans, and Amsonia hubrichtii, with the nucleotide sequence of the N-methyltransferase involved in vindoline biosynthesis, revealed eight new homologous methyltransferases. This thesis describes the identification, molecular cloning, recombinant expression and biochemical characterization of two picrinine NMTs, one from V. minor and one from R. serpentina, a perivine NMT from C. roseus, and an ajmaline NMT from R. serpentina. While these TLMTs were expressed and functional in planta, they were active at relatively low levels and their N-methylated alkaloid products were not apparent our from alkaloid isolates of the plants. It appears that, for the most part, these TLMTs, participate in apparently silent biochemical pathways, awaiting the appropriate developmental and environmental cues for activity.

Anticipated Guilt and Ethical Consumption: The Moderating Role of Consumers’ Socially Responsible Consumption Behaviour

Recent research in the marketing literature has indicated that, while consumers’ interests in ethical products are growing, demand for such products still remains weak. Previous research has indicated that anticipated guilt can have a positive effect on ethical consumption. Thus, the objective of the current study is to investigate the moderating role of consumers’ socially responsible consumption behaviour (SRCB) on the relationship between anticipated guilt and ethical consumption. Specifically, the current study hypothesizes that, when viewing a guilt ad, high (vs. low) SRCB individuals will generate higher, ethical purchase intentions, willingness to pay an ethical premium, and attitudes toward an ethical brand. The findings from the two experimental studies indicate that, when viewing a guilt ad for an ethical product, high SRCB individuals are willing to pay a higher ethical premium and generate more favourable brand attitudes than low SRCB individuals. However, when viewing a non-guilt ad, high SRCB individuals did not differ from low SRCB individuals in their willingness to pay an ethical premium or brand attitudes. Further, consumers’ socially conscious self-identity was explored as a mediator of these effects. By understanding the moderating role that SRCB plays in the relationship between anticipated guilt and ethical consumption, this paper intends to assist marketers in understanding for which consumers a guilt appeal is an appropriate strategy in marketing ethical products.

Pauvreté des familles monoparentales. Le Canada et le Québec dans l’univers des régimes providentiels

La pauvreté monoparentale touche de nombreux pays développés au point que la monoparentalité est restée pendant longtemps associée à la pauvreté. Malgré les efforts de l’État-providence, les systèmes de protection sociale s’avèrent souvent inefficaces et inadaptés aux changements de la structure familiale et de la diversité des modes de résidence. Or, les situations des familles monoparentales ne sont pas semblables d’une société à une autre. Certaines sociétés adoptent des régimes providentiels qui offrent des conditions plutôt favorables aux familles quel que soit leur statut (monoparental ou biparental), tandis que d’autres se caractérisent par des systèmes moins égalitaires et moins favorables aux familles monoparentales. Notre thèse cherche à déconstruire le lien entre la pauvreté et la monoparentalité en poussant plus loin la réflexion sur les régimes providentiels. Le bien-être des familles monoparentales dépend des arrangements institutionnels des régimes qui assurent des ressources à travers les trois piliers que sont l’État, le marché et la famille. Certaines sociétés favorisent le pilier de l’État comme principal pourvoyeur de ressources alors que d’autres mettent l’accent sur le marché. Dans d’autres cas, la solidarité familiale est considérée comme étant fondamentale dans le bien-être des individus. Parmi ces trois piliers, il est souvent difficile de trouver la combinaison la plus appropriée pour protéger les familles monoparentales et leur assurer une certaine sécurité et une autonomie économique. Lorsque les gouvernements adoptent la politique de prise en charge des familles monoparentales, ces dernières deviennent très dépendantes de l’assistance sociale et des programmes d’aide publique. Dans un contexte libéral, les mesures d’incitation au travail qui visent les chefs de famille monoparentale ont plutôt tendance à réduire cette dépendance. Mais dans bien des cas, les familles monoparentales sont amenées à dépendre d’un revenu du marché qui ne les aide pas toujours à sortir de la pauvreté. Lorsque nous regardons le troisième pilier, celui de la famille, il s’avère souvent que les solidarités qui proviennent de cette source sont limitées et occasionnelles et nécessitent parfois une réglementation spéciale pour les dynamiser (comme c’est le cas des pensions alimentaires). L’articulation de ces piliers et leur apport au bien-être des familles monoparentales soulève une question fondamentale : Quelles sont les possibilités pour les chefs de famille monoparentale de fonder et maintenir un ménage autonome qui ne soit ni pauvre ni dans la dépendance par rapport à une seule source de revenu qui peut provenir de l’État, du marché ou de la famille ? Pour examiner cette question, nous avons procédé à des comparaisons internationales et interprovinciales à partir des données du Luxembourg Income Study (LIS). Le choix des comparaisons internationales est très utile pour situer le Québec dans un environnement de régimes providentiels avec un cadre théoriquement et conceptuellement structuré pour comprendre les politiques de lutte contre la pauvreté monoparentale. Cette recherche montre principalement que la pauvreté monoparentale est très problématique dans les régimes qui privilégient le marché comme principal pilier de bien-être. Elle l’est aussi dans certains pays qui privilégient les transferts et adoptent des politiques de prise en charge envers les familles monoparentales qui restent largement désavantagées par rapport aux familles biparentales. Par contre, certains régimes favorisent une complémentarité entre ce que peuvent tirer les familles du marché du travail et ce qu’elles peuvent tirer des ressources de l’État. Généralement, ce genre d’approche mène vers des taux de pauvreté plus faibles chez les familles monoparentales. Le Québec fait partie des sociétés où le marché représente une source fondamentale de bien-être. Toutefois, la pauvreté monoparentale est moins problématique que chez ses voisins d’Amérique du Nord. De nombreux chefs de famille monoparentale dans la province occupent des emplois à temps plein sans être désavantagés. Cependant, les chefs de famille monoparentale qui occupent des emplois à temps partiel sont largement plus exposés à la pauvreté. Pourtant, dans certaines sociétés, particulièrement aux Pays-Bas, ce statut d’emploi offre des conditions meilleures pour la conciliation travail-famille.
