No full textMinidonta flammulina n. sp. (Fig. 2) MATÉRIEL- TYPE. — Holotype et paratypes 1-7 (MNHN), paratypes 8-9 (BPBM 259289). LOCALITÉ- TYPE. — Mangareva. Ganhutu, 23°04,6’S, 134°56,6’W, terrain découvert herbeux sous cocotiers, sol très léger, sablonneux, 17.IX.1997. ÉTYMOLOGIE. — Par ses flammules de couleur roux sur fond clair, l’espèce ressemble en miniature aux espèces du genre Flammulina (Charopidae). Le nom est utilisé en apposition. DESCRIPTION (HOLOTYPE) Coquille grande pour le genre, globuleuse déprimée, à spire modérément élevée (H/D = 0,622), formée de six tours, régulièrement convexes, séparés par une suture profonde. Protoconque d’1,5 tour environ, en apparence lisse, mais avec des traces de costulation axiale au voisinage de la suture. Transition protoconque/téléoconque indistincte. Sculpture de la téléoconque constituée de côtes primaires épaisses, peu élevées, au nombre de 109 sur le dernier tour, espacées de 75-85 µm; microsculpture de costules secondaires serrés, couvrant toute la surface de la coquille, même au niveau des côtes primaires, espacées de 5-6 µm sur les deux premiers tours de téléoconque, usés ou obsolètes sur les deux derniers tours, croisant de très fins filets spiraux avec lesquels elles forment un réseau à mailles carrées. Ombilic étroit, occupant 17,6 % du diamètre. Ouverture en croissant de lune, péristome légèrement prosocline, non continu. Barrières aperturales s’étendant sur un quart de tour environ: trois lamelles pariétales, intervalle entre Pr1, la plus haute, et la suivante (Pr3) près du double de celui qui sépare les deux autres; Pr2 absente, Pr1 et Pr3 en forme de feuillet recourbé, Pr4 plus basse; une très forte lamelle columellaire; quatre lamelles palatales, P1 très réduite, une trace entre P1 et P2, et une autre entre P2 et P3. Couleur non uniforme, flammules brun foncé sur fond clair, blanc crayeux. Certains individus présentent une trace de lamelle pariétale dans l’intervalle entre Pr3 et Pr4; la trace palatale entre P1 et P2 est très constante, celle entre P2 et P3 peut manquer et une troisième peut être présente entre P3 et P4. Dimensions H = 1,84 mm; D = 2,96 mm. Dimensions moyennes de dix individus adultes (holotype et paratypes) et intervalles (Tableau 4): H = 1,57 mm (1,40-1,84); D = 2,64 (2,44-2,96); rapport D/U = 7,25 (5,69-9,00); nombre de côtes sur le dernier tour = 108,8 (92-129). REMARQUES Le système de barrières aperturales de Minidonta flammulina est présent chez plusieurs autres espèces de Minidonta des Gambier (M. micra, M. taunensis, M. vallonia), qui en diffèrent par une taille moindre, un ombilic plus ouvert, et/ou l’absence de maculations (Tableau 3). L’étroitesse de l’ombilic rappelle en fait M. taravensis, qui diffère par sa sculpture plus grossière, ses tours très convexes, à suture très profonde, et la présence de Pr2 dans l’intervalle correspondant chez M. flammulina au grand intervalle séparant Pr1 et Pr3; la morphologie particulière de Pr3, en forme de feuillet recourbé, individualise cependant les deux espèces vis à vis des autres Minidonta des Gambier. Il est possible que les dispositifs aperturaux des deux espèces soient dérivés l’un de l’autre, soit par simplification (perte de Pr2 chez M. flammulina) soit par complexification (acquisition de Pr2 chez M. taravensis).Published as part of Abdou, Ahmed & Bouchet, Philippe, 2000, Nouveaux gastéropodes Endodontidae et Punctidae (Mollusca, Pulmonata) récemment éteints de l'archipel des Gambier (Polynésie), pp. 689-707 in Zoosystema 22 (4) on pages 694-696, DOI: 10.5281/zenodo.539986
Eritrean, Ethiopian, Somali and Sudanese Communities in Western Australia
No full textDepression has been identified as a significant global health problem. However, to date, there has been little research into the most appropriate strategies to use in the prevention of depression. There is even less research about the understanding that people of culturally and linguistically diverse backgrounds have of the conditions encompassed by the term ‘depression’, (or more culturally and linguistically specific representations of unhappiness) and of the ways in which these conditions may be prevented.
The Listening to Diverse Voices: multicultural mental health promotion research project, a collaboration between Murdoch University and the East Metropolitan Population Health Unit, funded by Healthway, investigated these issues within a number of minority communities and in consultation with service providers in Perth, Western Australia, during the period 2001-2004. The objectives of the research were to identify cultural differences in understandings and experiences of ‘depression’ and appropriate ways of dealing with such issues.
The research used focus groups and interviews to explore understandings of social and emotional well-being and of ‘depression’ among members of a number of communities in Perth. These included Sudanese, Somali, Eritrean, Ethiopian, Croatian, Bosnian and Chinese communities and also Indigenous Australians. The information in this document however pertains only to the Horn of Africa communities in the study. Service providers too were canvassed for their concerns and experiences. Participants came from a variety of ethnic and class backgrounds, and while some entered Australia under the ‘skilled migrant’ category, many came under the ‘humanitarian program’ and had experienced life in refugee camps in other parts of the world before coming to Australia. Over 200 people participated in the research.
Because of cultural sensitivities, separate focus groups were conducted with men, women and young people for some communities. Within the Sudanese community separate focus groups were conducted with North and South Sudanese and, within the Ethiopian community, separate focus groups were undertaken with Oromo men and women. In the Eritrean community Arabic speaking men and Tigre speaking men participated in separate focus groups. Most focus groups, apart from those with youth, were conducted by bilingual facilitators, in community languages, and were then transcribed verbatim and translated. Some focus groups and all interviews were conducted in English.
It is important to note that the use of such groupings does not imply internal homogeneity of individuals, experiences, perspectives or concerns.
All interviews and focus groups were undertaken using a semi-structured, standardised schedule. Interview and focus group questions were designed to elicit participants’ understandings of mental health, social and emotional well-being, depression, causes of depression and recommendations for appropriate treatments and/or interventions. Interviews and focus groups were taped, transcribed and translated, where necessary, and the transcripts studied for common themes. These themes were then taken back to the communities for comment, and the summaries adapted according to this further feedback. While it is not claimed that the participants are ‘representative’ of the communities of which they are members, the research team feels confident that the issues identified are among the most common concerns of these communities.
The most significant finding was that issues seen by communities as likely to cause emotional (or mental) distress, are social and settlement issues, rather than being biomedical in nature, or being seen as the result of pre-arrival trauma (although this was one factor identified). The result of this is that while some of the issues may be dealt with from within a ‘population health’ perspective and organisation, most are outside population health parameters. Therefore this information is being provided to a wider audience in the hope that other government departments, non-government organisations and individuals will also take action to address some of these issues.
This document contains brief summaries of the various issues identified by the Horn of Africa communities as leading to what Westerners might call ‘depression’ and their suggestions for solutions. Our commitment to hearing the voices of these communities themselves is reflected in our use of direct quotations taken from the interviews and focus groups. We also provide profiles of the communities, including historical and cultural information and a brief history of arrival in Western Australia. This document provides information about the new and emerging communities from the Horn of Africa. Horn of Africa.

Sculpture axiale constituée de côtes sigmoïdes, lamelleuses, espacées de 90 µm environ, au nombre de 77 sur le dernier tour, et de très fins costules très serrés, au nombre de six à huit par intervalle entre les côtes principales; microsculpture spirale indistincte, mais dont le croisement avec les costules axiaux produit une très fine réticulation. Ouverture semicirculaire, péristome non continu, prosocline, pourvue d’une lamelle pariétale simple, très basse, visible aussi loin que l’on peut observer dans l’ouverture.

Trois individus de l’espèce-type <i>R. insolens</i> ont été récoltés à Gatavake en 1997 et 12 autres à Taravai; ils confirment les caractères de l’holotype, seul individu connu de Solem lorsqu’il a établi le genre et l’espèce: <i>Rikitea insolens</i> est caractérisée par un très grand ombilic, une lamelle pariétale unique, très forte, et de fortes côtes axiales très espacées. <i>R. tapinoptyx</i> s’en distingue aisément par la finesse des côtes axiales et l’ombilic plus étroit, et au fond c’est uniquement la barrière aperturale réduite à une lamelle pariétale qui nous conduit à la rapprocher de <i>Rikitea</i>. En fait, l’absence des premiers tours de spire ne permet même pas d’exclure que l’espèce appartienne en fait à la famille des Charopidae, classiquement considérée comme dépourvue de barrière aperturale, mais dont Solem (1983) a montré que certains genres (tels que <i>Lagivala</i>, <i>Vatusila</i>, <i>Graeffedon</i>, <i>Lauopa</i>, tous de Solem, 1983) sont pourvus de barrières aperturales bien développées. Toutefois, tous ces genres sont présents beaucoup plus à l’Ouest dans le Pacifique et le seul genre de Charopidae présent en Polynésie (Solem 1983; Preece 1995), <i>Sinployea</i> Solem, 1983, est dépourvu de barrière aperturale. L’appartenance même de <i>Rikitea insolens</i> à la famille des Endodontidae demande à être confirmée par les caractères de la sculpture de la protoconque (usée chez tous les exemplaires examinés) et n’est ici suivie que sur l’autorité de Solem (1983).</p>Published as part of <i>Abdou, Ahmed & Bouchet, Philippe, 2000, Nouveaux gastéropodes Endodontidae et Punctidae (Mollusca, Pulmonata) récemment éteints de l'archipel des Gambier (Polynésie), pp. 689-707 in Zoosystema 22 (4)</i> on page 702, DOI: <a href="http://zenodo.org/record/5399867">10.5281/zenodo.5399867</a>
The Structure of Unstable Power Systems
No full textA power system is modeled by an interaction form, the solution of which is called a settlement. By stability we mean the existence of some settlement for any preference profile. Like in other models of power structure, instability is equivalent to the existence of a cycle. Structural properties of the system like maximality, regularity, superadditivity, subadditivity and exactness are defined and used to determine the type of instability that may affect the system. A Stability Index is introduced. Loosely speaking this index measures the difficulty of the emergence of configurations that produce a deadlock. As applications we have a characterization of solvable game forms, an analysis of the structure of their instability and a localization of their stability index in case where solvability fails.Interaction Form, Effectivity Function, Stability Index, Nash Equilibrium, Strong Equilibrium, Solvability, Acyclicity, Nakamura Number, Collusion

The impact of M&A on the Nigerian financial market: a pre-post analysis
No full textThis paper examines the impact of mergers and acquisitions (M&A) on the financial performance of the Nigerian market after consolidation. The authors use data from all Nigerian banks that survived the consolidation between 2001 and 2009. Logistic regression models are structured to determine the influence of M&A activities on the financial performance of the Nigerian market. Also, the authors critically evaluate the findings by shedding the light on the
lessons other developing nations can learn from the Nigerian market. The results show that M&A have a positive influence on the financial performance of the Nigerian market. Still, M&A are not enough to achieve the wider objectives of banking sector reform. Towards this end, corporate governance reform must take place vis-à-vis consolidation exercises especially when these M&A are regulatory based rather than market based. The investigation uses a novel approach by comparing pre- and post- M&A results performance of merged banks as well as comparing these results with non-merged banks. Finally, the paper puts the results in context of the wider reform context and considers the effectiveness of the M&A as a tool for banking sector reform in developing countries. The investigation offers insights into the policy of banking consolidation which can be useful for policy makers in Nigeria and other
similar economies
Interaction Sheaves on Continuous Domains
No full textWe introduce a description of the power structure which is inherent in a strategic gameform using the concept of an interaction sheaf. The latter assigns to each open set of outcomes a set of interaction arrays, specifying the changes that coalitions can make if outcome belongs to this open set. The interaction sheaf generalizes the notion of effectivity functions which has been widely used in implementation theory, taking into consideration that changes in outcome may be sustained not only by single coalitions but possibly by several coalitions, depending on the underlying strategy choices. Also, it allows us to consider gameforms with not necessarily finite sets of outcomes, generalizing the results on solvability of game forms obtained in the finite case in Abdou and Keiding [Abdou, J., Keiding, H., 2003. On necessary and sufficient conditions for solvability of game forms. Mathematical Social Sciences 46, 243-260]
