Three new species of Tubificinae, Oligochaeta, from two plateau lakes in Southwest China

Three new species of Tubificinae (Naididae, Oligochaeta), Varichaetadrilus vestibulatus n. sp., Aulodrilus apeniatus n. sp., and Ilyodrilus mesoprostatus n. sp., are reported from Fuxian Lake and Xingyun Lake of Yunnan Province, Southwest China. V. vestibulatus differs from its allies by possessing modified spermathecal chaetae and thinner cylindrical penial sheaths. A. apeniatus is unique in the genus by having no penis. I. mesoprostatus is distinguishable from congeners by its prostate glands joining middle portion of atria and having concave, cone-shaped cuticular penial sheaths. Twenty-eight species of freshwater oligochaetes have hitherto been recorded from Yunnan Province, including five endemic species from three plateau lakes.

Uniformity of karyotypes in Ligularia (Asteraceae : Senecioneae), a highly diversified genus of the eastern Qinghai-Tibet Plateau highlands and adjacent areas

Ligularia, a highly diversified genus in the eastern Qinghai-Tibet Plateau and adjacent areas, was chosen as a suitable subject in which to study speciation patterns in this 'hot spot' area at the chromosomal level. Chromosome numbers and karyotypes were studied in 23 populations of 14 species, most of which are endemic to this area. The basic number x = 29 was confirmed for all species. Ligularia virgaurea was found to have diploid and triploid cytotypes, 2n = 58 and 87. Other species are only diploid, with 2n = 58. The karyotypes of all populations within any species, and all species spanning most sections and covering most of the morphological range in Ligularia, are very similar to each other, belonging to type 2A according to Stebbin's classification. This karyotype was also found in its close allies, e.g. Cremanthodium, Ligulariopsis, Parasenecio, and Sinacalia. Aneuploid reduction of chromosome number from 2n = 60 to 58 and karyotypic variation was found in Ligularia and its allies. Such a chromosomal pattern with few polyploids infers that variation of karyotype structure at the diploid level seems to be the predominant feature of chromosomal evolution in this group and sympatric speciation via hybridization and polyploidization has played a minor role in its species diversity.

Moral shielding: A grounded theory of integrity maintenance in multidisciplinary teams

Using a classic grounded theory methodology (CGT), this study explores the phenomenon of moral shielding within mental health multidisciplinary teams (MDTS). The study was located within three catchment areas engaged in acute mental health service practice. The main concern identified was the maintenance of a sense of personal integrity during situational binds. Through theoretical sampling thirty two practitioners, including; doctors, nurses, social workers, occupational therapists, counsellors and psychologists, where interviewed face to face. In addition, emergent concepts were identified through observation of MDTs in clinical and research practice. Following a classic grounded theory methodology, data collection and analysis occurred simultaneously. A constant comparative approach was adopted and resulted in the immergence of three sub- core categories; moral abdication, moral hinting and pseudo-compliance. Moral abdication seeks to re-position within an event in order to avoid or deflect the initial obligation to act, it is a strategy used to remove or reduce moral ownership. Moral gauging represents the monitoring of an event with the goal of judging the congruence of personal principles and commitments with that of other practitioners. This strategy is enacted in a bid to seek allies for the support of a given moral position. Pseudo-compliance represents behaviour that hides desired principles and commitments in order to shield them from challenge. This strategy portrays agreement with the dominant position within the MDT, whilst holding a contrary position. It seeks to preserve a reservoir of emotional energy required to maintain a sense of personal integrity. Practitioners who were successful in enacting moral shielding were found to not experience significant emotional distress associated with the phenomenon of moral distress; suggesting that these practitioners had found mechanisms to manage situational binds that threatened their sense of personal integrity.

Challengers to provisional republicanism: the official republican movement, people’s democracy and the Irish republican socialist party, 1968–98

The Provisional IRA and its political wing Sinn Féin have attracted by far the greatest scholarly interest of all the players in the Northern Irish conflict. This emphasis is perfectly legitimate, given the centrality of the Provos to so many turning-points in the conflict, from the collapse of Stormont in the early 1970s to the hunger strikes of the following decade and the ceasefires which were followed by the Belfast Agreement. My project, however, looks at political groups that at one time or another challenged the Provos for leadership of the militant, anti-state constituency in Northern Ireland (chiefly based in the Catholic working class). Although never as large or influential as the Provisional republicans, groups such as the Official IRA and the Irish Republican Socialist Party sometimes had a discernible impact on the course of events which is overlooked by most studies, and often pioneered ideas and tactics that were later adopted by the Provos themselves. The idea that republicans should embrace political action and work in broad campaigning alliances was promoted by the IRSP and socialist groups such as People’s Democracy before it was taken up by Gerry Adams and his allies, while the Official IRA supported the principle of a settlement based on democratization of the Northern Irish state, which was later accepted by Sinn Féin in the form of the Belfast Agreement. The goal of my research is to provide a novel perspective on the conflict in Northern Ireland, while engaging with theoretical debates about its character.

Shifting Loyalties: World War I and the Conflicted Politics of Patriotism in the British Caribbean

This dissertation examines how the crisis of World War I impacted imperial policy and popular claims-making in the British Caribbean. Between 1915 and 1918, tens of thousands of men from the British Caribbean volunteered to fight in World War I and nearly 16,000 men, hailing from every British colony in the region, served in the newly formed British West Indies Regiment (BWIR). Rousing appeals to imperial patriotism and manly duty during the wartime recruitment campaigns and postwar commemoration movement linked the British Empire, civilization, and Christianity while simultaneously promoting new roles for women vis-à-vis the colonial state. In Jamaica and Trinidad and Tobago, the two colonies that contributed over seventy-five percent of the British Caribbean troops, discussions about the meaning of the war for black, coloured, white, East Indian, and Chinese residents sparked heated debates about the relationship among race, gender, and imperial loyalty.

To explore these debates, this dissertation foregrounds the social, cultural, and political practices of BWIR soldiers, tracing their engagements with colonial authorities, military officials, and West Indian civilians throughout the war years. It begins by reassessing the origins of the BWIR, and then analyzes the regional campaign to recruit West Indian men for military service. Travelling with newly enlisted volunteers across the Atlantic, this study then chronicles soldiers' multi-sited campaign for equal status, pay, and standing in the British imperial armed forces. It closes by offering new perspectives on the dramatic postwar protests by BWIR soldiers in Italy in 1918 and British Honduras and Trinidad in 1919, and reflects on the trajectory of veterans' activism in the postwar era.

This study argues that the racism and discrimination soldiers experienced overseas fueled heightened claims-making in the postwar era. In the aftermath of the war, veterans mobilized collectively to garner financial support and social recognition from colonial officials. Rather than withdrawing their allegiance from the empire, ex-servicemen and civilians invoked notions of mutual obligation to argue that British officials owed a debt to West Indians for their wartime sacrifices. This study reveals the continued salience of imperial patriotism, even as veterans and their civilian allies invoked nested local, regional, and diasporic loyalties as well. In doing so, it contributes to the literature on the origins of patriotism in the colonial Caribbean, while providing a historical case study for contemporary debates about "hegemonic dissolution" and popular mobilization in the region.

This dissertation draws upon a wide range of written and visual sources, including archival materials, war recruitment posters, newspapers, oral histories, photographs, and memoirs. In addition to Colonial Office records and military files, it incorporates previously untapped letters and petitions from the Jamaica Archives, National Archives of Trinidad and Tobago, Barbados Department of Archives, and US National Archives.

Dispersal and Integration in Female Chimpanzees

In chimpanzees, most females disperse from the community in which they were born to reproduce in a new community, thereby eliminating the risk of inbreeding with close kin. However, across sites, some females breed in their natal community, raising questions about the flexibility of dispersal, the costs and benefits of different strategies and the mitigation of costs associated with dispersal and integration. In this dissertation I address these questions by combining long-term behavioral data and recent field observations on maturing and young adult females in Gombe National Park with an experimental manipulation of relationship formation in captive apes in the Congo.

To assess the risk of inbreeding for females who do and do not disperse, 129 chimpanzees were genotyped and relatedness between each dyad was calculated. Natal females were more closely related to adult community males than were immigrant females. By examining the parentage of 58 surviving offspring, I found that natal females were not more related to the sires of their offspring than were immigrant females, despite three instances of close inbreeding. The sires of all offspring were less related to the mothers than non-sires regardless of the mother’s residence status. These results suggest that chimpanzees are capable of detecting relatedness and that, even when remaining natal, females can largely avoid, though not eliminate, inbreeding.

Next, I examined whether dispersal was associated with energetic, social, physiological and/or reproductive costs by comparing immigrant (n=10) and natal (n=9) females of similar age using 2358 hours of observational data. Natal and immigrant females did not differ in any energetic metric. Immigrant females received aggression from resident females more frequently than natal females. Immigrants spent less time in social grooming and more time self-grooming than natal females. Immigrant females primarily associated with resident males, had more social partners and lacked close social allies. There was no difference in levels of fecal glucocorticoid metabolites in immigrant and natal females. Immigrant females gave birth 2.5 years later than natal females, though the survival of their first offspring did not differ. These results indicate that immigrant females in Gombe National Park do not face energetic deficits upon transfer, but they do enter a hostile social environment and have a delayed first birth.

Next, I examined whether chimpanzees use condition- and phenotype-dependent cues in making dispersal decisions. I examined the effect of social and environmental conditions present at the time females of known age matured (n=25) on the females’ dispersal decisions. Females were more likely to disperse if they had more male maternal relatives and thus, a high risk of inbreeding. Females with a high ranking mother and multiple maternal female kin tended to disperse less frequently, suggesting that a strong female kin network provides benefits to the maturing daughter. Females were also somewhat less likely to disperse when fewer unrelated males were present in the group. Habitat quality and intrasexual competition did not affect dispersal decisions. Using a larger sample of 62 females observed as adults in Gombe, I also detected an effect of phenotypic differences in personality on the female’s dispersal decisions; extraverted, agreeable and open females were less likely to disperse.

Natural observations show that apes use grooming and play as social currency, but no experimental manipulations have been carried out to measure the effects of these behaviors on relationship formation, an essential component of integration. Thirty chimpanzees and 25 bonobos were given a choice between an unfamiliar human who had recently groomed or played with them over one who did not. Both species showed a preference for the human that had interacted with them, though the effect was driven by males. These results support the idea that grooming and play act as social currency in great apes that can rapidly shape social relationships between unfamiliar individuals. Further investigation is needed to elucidate the use of social currency in female apes.

I conclude that dispersal in female chimpanzees is flexible and the balance of costs and benefits varies for each individual. Females likely take into account social cues present at maturity and their own phenotype in choosing a settlement path and are especially sensitive to the presence of maternal male kin. The primary cost associated with philopatry is inbreeding risk and the primary cost associated with dispersal is delay in the age at first birth, presumably resulting from intense social competition. Finally, apes may strategically make use of affiliative behavior in pursuing particular relationships, something that should be useful in the integration process.

Addressing time intervals

One of the fundamental questions regarding the temporal ontology is what is time composed of. While the traditional time structure is based on a set of points, a notion that has been prevalently adopted in classical physics and mathematics, it has also been noticed that intervals have been widely adopted for expre~sion of common sense temporal knowledge, especially in the domain of artificial intelligence. However, there has been a longstanding debate on how intervals should be addressed, leading to two different approaches to the treatment of intervals. In the first, intervals are addressed as derived objects constructed from points, e.g., as sets of points, or as pairs of points. In the second, intervals are taken as primitive themselves. This article provides a critical examination of these two approaches. By means of proposing a definition of intervals in terms of points and types, we shall demonstrate that, while the two different approaches have been viewed as rivals in the literature, they are actually reducible to logically equivalent expressions under some requisite interpretations, and therefore they can also be viewed as allies.

The Analogical Peacock Hypothesis: The Sexual Selection of Mind-Reading and Relational Cognition in Human Communication

This integrative review presents a novel hypothesis as a basis for integrating two evolutionary viewpoints on the origins of human cognition and communication, the sexual selection of human mental capacities, and the social brain hypothesis. This new account suggests that mind-reading social skills increased reproductive success and consequently became targets for sexual selection. The hypothesis proposes that human communication has three purposes: displaying mind-reading abilities, aligning and maintaining representational parity between individuals to enable displays, and the exchange of propositional information. Intelligence, creativity, language, and humor are mental fitness indicators that signal an individual’s quality to potential mates, rivals, and allies. Five features central to the proposed display mechanism unify these indicators, the relational combination of concepts, large conceptual knowledge networks, processing speed, contextualization, and receiver knowledge. Sufficient between-mind alignment of conceptual networks allows displays based upon within-mind conceptual mappings. Creative displays communicate previously unnoticed relational connections and novel conceptual combinations demonstrating an ability to read a receiver’s mind. Displays are costly signals of mate quality with costs incurred in the developmental production of the neural apparatus required to engage in complex displays and opportunity costs incurred through time spent acquiring cultural knowledge. Displays that are fast, novel, spontaneous, contextual, topical, and relevant are hard-to-fake for lower quality individuals. Successful displays result in elevated social status and increased mating options. The review addresses literatures on costly signaling, sexual selection, mental fitness indicators, and the social brain hypothesis; drawing implications for nonverbal and verbal communication.

Government decisions before and during the First World War and the living standards in Germany during a drastic natural experiment

The First World War hit Germany severely, particularly the agricultural sector, because the outbreak came unexpected and its duration exceeded all expectations. Many resources necessary for agricultural production were required by the war economy and led to shortages and shrinking supplies. Many agricultural laborers were drafted and the blockade imposed by the allies prevented Germany from a great deal of imports. As a consequence, the nutritional situation was devastating, particularly after 1916, and hit all groups of the German society. The period under observation provides one of most drastic natural experiments in the 20th century. This study uses anthropometric data from German soldiers who served in the Second World War to trace living standards between the 1900s and the 1920s. In contrast to other approaches, this paper is able to distinguish between social groups by occupation, religious denominatio\n, regional origin, and city size. The results suggest that although all social strata were hit by famine conditions, the height of farmers, urban citizens, Catholics, and especially individuals born in the highly integrated food-import regions along the coast and the banks of the Rhine declined most.

Faire parler les morts. Sur Jan Karski et la controverse Lanzmann-Haenel

The Second World War has inspired many French novelists since 1945. Yet, very few of these novels have been harshly criticized by either historians or other critics, Les Bienveillantes (2006) by Jonathan Littell and Jan Karski (2009) by Yannick Haenel being two notable exceptions. This article revisits the controversy between the novelist Yannick Haenel and the critic and film-maker Claude Lanzmann. First, it shows that the important questions raised by Lanzmann are not void of ambiguity, notably because key terms at the heart of this controversy (truth, fiction or even history) were used loosely. Second, this article compares the documentary Le Rapport Karski (2010) to other texts written by Karski and to the full transcription of the interview he gave to Lanzmann in 1978: it shows how Lanzmann's 2010 documentary distorts Karski's testimony to make it comply with historical perspectives that most historians would agree with today. Finally, the author of this article regrets that this controversy did not allow the debate to move beyond the military non-intervention of the Allies.

Ultrastructure and phylogeny of peridinioid dinoflagellates

Os dinoflagelados são um grupo muito diverso de protistas que possuem um conjunto de características pouco comuns. Os peridinióides são dinoflagelados com teca que é formada por seis séries latitudinais de placas, incluindo a série cingular e um anel incompleto de placas intercalares anteriores, embora as últimas estejam ausentes em algumas espécies de Peridiniopsis. São dinoflagelados com simetria bilateral em relação ao plano apical que contem o eixo dorso-ventral. Na série sulcal há apenas uma placa posterior que contacta com o limite ventral de duas grandes placas antapicais. Entre os peridinióides, a presença ou ausência de um poro apical e o número de placas no cíngulo são geralmente consideradas marcas filogenéticas importantes ao nível de género ou família. Actualmente, a definição de Peridinium Ehrenberg, o dinoflagelado mais comum de água doce, inclui organismos com combinações diferentes destas duas características. Trabalhos anteriores sobre a ultrastrutura e afinidade filogenética das espécies tipo de Peridinium, P. cinctum, e Peridiniopsis Lemmermann, P. borgei também sugerem a necessidade de reexaminar as relações taxonómicas dos peridinióides. Esta tese combina o estudo ultrastrutural de uma selecção de espécies com hipóteses filogenéticas baseadas nas sequências de LSU rDNA, para aumentar o nosso conhecimento das diferenças e afinidades dentro dos peridinióides. Tem como objectivo aumentar o nosso conhecimento das características individuais das células que possam levar a reconhecer sinapomorfias que possam ser usadas como marcadores dos peridinióides como um todo e dos seus subgrupos. As espécies escolhidas para exame pormenorizado foram: Peridinium palatinum Lauterborn, de um grupo com duas placas intercalares anteriores, seis placas cingulares e sem poro apical; Peridinium lomnickii Wo!oszy"ska, de um grupo com poro apical, três placas intercalares e seis cingulares; Peridiniopsis berolinensis (Lemmermann) Bourrelly, uma espécie heterotrófica com poro apical, sem placas intercalares e com seis placas cingulares; e Sphaerodinium cracoviense Wo!oszy"ska, um membro de um género de formas com teca com um tipo de tabulação marginalmente peridinióide, com um suposto poro apical e quatro placas intercalares anteriores. Peridinium palatinum difere de Peridinium e Peridiniopsis típicos, quer em características da teca, quer internas. As diferenças estimadas entre as sequências parciais de LSU rDNA de P. palatinum e a espécie próxima P. pseudolaeve, relativamente a P. cinctum são comparativamente grandes e, juntamente com a topologia da árvore filogenética, apoiam a separação de P. palatinum e formas próximas ao nível de género. Palatinus nov. gen. foi, então, descrito com as novas combinações Palatinus apiculatus nov. comb. (espécie tipo; sin. Peridinium palatinum), P. apiculatus var. laevis nov. comb. e P. pseudolaevis nov. comb.. As características distintivas de Palatinus incluem uma superfície das placas lisa ou um tanto granulosa, mas não areolada, um grande pirenóide central penetrado por canais citoplasmáticos e de onde radiam lobos plastidiais, e a presença de uma fiada microtubular homóloga à de um pedúnculo. As células de Palatinus saem da teca pela zona antapicalpos- cingular. Peridinium lomnickii apresenta tabulação semelhante às formas marinhas, produtoras de quistos calcários, do género Scrippsiella A.R. Loeblich. Para comparação, adicionámos novas observações ultrastruturais de S. trochoidea. Peridinium lomnickii tem uma combinação de características diferente de Peridinium, Peridiniopsis e Scrippsiella. As hipóteses filogenéticas baseadas em DNA colocam P. lomnickii no mesmo ramo que Pfiesteria Steidinger et Burkholder, Tyrannodinium e outras Pfiesteriaceae, com as quais partilha um "microtubular basket" e uma ligação peculiar entre duas placas do sulco. As características distintivas do novo género proposto Chimonodinium gen. ined. incluem, além da tabulação, a ausência de pirenóides, a presença de um "microtubular basket" com quatro ou cinco fiadas sobrepostas de microtúbulos associados a um pequeno pedúnculo, um sistema pusular com tubos pusulares bem definidos ligados aos canais flagelares, e a produção de quistos não calcários. Peridiniopsis berolinensis partilha várias características significativas com Pfiesteria e afins, como um "microtubular basket" com a capacidade de suportar um tubo de alimentação, quimiossensibilidade para encontrar presas apropriadas, o modo de natação junto às presas e a organização geral da célula. Hipóteses filogenéticas com base em LSU rDNA confirmam a afinidade entre P. berolinensis e Pfiesteria bem como a relação mais remota com a espécie tipo de Peridiniopsis, P. borgei. Estas razões justificam a proposta de Tyrannodinium gen. nov., uma nova Pfiesteriaceae que difere de outros membros do grupo por viver em água doce e nos pormenores da tabulação. Sphaerodinium cracoviense revelou a tabulação típica do género Sphaerodinium, que apresenta um número de placas intercalares superiores e pos-cingulares maior que o que é típico em peridinióides: 4 e 6, respectivamente. Observações em SEM mostraram uma estrutura apical diferente da dos peridinióides, e um sulco apical numa das placas fazendo lembrar a área apical de alguns woloszynskióides. Os pormenores do aparelho flagelar e do sistema pusular ligam o Sphaerodinium aos woloszynskióides em geral e ao género Baldinia em particular, mas não aos peridinióides. O volumoso estigma de S. cracoviense revelou ser extraplastidial e de um modelo único, composto por elementos que se encontram em woloszynskióides, mas nunca encontrados anteriormente juntos. A análise filogenética baseada nas sequências parciais de LSU rDNA também sugerem uma maior proximidade de S. cracoviense com os woloszynskióides do que com os peridinióides. Futuras análises pormenorizadas de dinoflagelados peridinióides, em especial entre os do numeroso grupo de espécies com poro apical, serão necessárias para clarificar as suas relações taxonómicas; e a produção de descrições melhoradas das características finas particulares das células serão um requisito para perceber a evolução dos caracteres dos peridinióides por forma a podermos identificar marcadores filogenéticos.

Islão transnacional e os fantasmas do colonialismo português

Este artigo examina a forma como as políticas colónias portuguesas de enquadramento do Islão na Guiné e em Moçambique evoluíram de uma representação do muçulmano como ameaça para uma imagem mais conciliadora, pela qual os muçulmanos poderiam ser potenciais aliados do poder português na guerra contra os movimentos nacionalistas. Sendo ambas as representações marcadas pela ambivalência, a primeira predominou até ao final da década de 50 e a segunda desenhou-se em meados dos anos 60, acompanhando o restante trajecto das guerras coloniais. As duas imagens corresponderam a diferentes formas de lidar com a dimensão transnacional do Islão e com o seu alegado impacto sobre o colonialismo português em África. O artigo analisa essas estratégias, abordando a participação que nelas teve a Igreja Católica, o aparelho central de poder e as suas ramificações locais nas colónias.
