Poems of Sheikh Muhammad al-Ghaly Ba
No full textThis volume contains seven poems handwritten by Muhammad al-Ghāli Ba. According to the author's son, Mountaga Ba, the poems were probably composed in the mid-1970s a time when the author lived in Mauritania, while working at the country's national radio station and serving as a special counsel to then president Moktar Ould Daddah (1924–2003). The poems adress various issues. The first is a call to action addressed to the Mauritianian youth, urging them to join in the collective work for the development of the country. The second poem is a hagiography on Ceerno Ahmad Nene Ba of Kaedi (Mauritania). The poem eulogizes the virtues of the patron. The third describes the event of Sharif Muhammad al-Habib's visit to the region of Fuuta region (Senegal), namely the village of Pate Galo. The fourth poem contains greetings and expresions of love addressed to the author's friends in the town of Kaedi. The fifth poem is a remembrance about good times. The author reminisces and praises the qualities of a woman named Jaari.The sixth poem describes one afternoon journey of the author. The seventh poem is a mournful praisesong in which the author laments the loss of a cherished person.Ce volume contient sept poèmes manuscrits de Muhammad al-Ghāli Ba.

Modern Biotechnology in New Zealand: Further Analysis of Data from the Biotechnology Survey 1998/99
No full textThe New Zealand Government has indicated a strong interest in fostering innovation and aims to concentrate on selected areas where New Zealand may be able to develop a new comparative advantage. One such area is biotechnology, which would build on New Zealand's existing comparative advantage in the primary sector dairy, forestry, meat, wool and horticulture). This paper aims to fill some of the gaps in our knowledge of biotechnology and innovation processes in New Zealand. It is based on the 1998/99 survey of modern biotechnology activity in New Zealand conducted by Statistics New Zealand in 2000. The survey was commissioned by the Ministry of Research, Science and Technology (MORST) mainly in order to produce statistics on the present position of the industry for planning purposes. The findings reported in this paper are based on further analysis of the survey data conducted by the author on behalf of MORST. Data are presented on the number, type and characteristics of enterprises involved in biotechnology in New Zealand. The paper presents data on enterprises that conduct R&D into modern biotech processes and includes analysis of the rate of innovation by biotech respondents compared to OECD estimates. Comparisons are also made between data from the New Zealand and Canadian biotech surveys
Factors affecting expansion success of bird populations in human-transformed environments: the marsh harrier Circus aeruginosus in the Ebro Valley
No full text[eng] Change in species geographic ranges is a natural phenomenon, but the rate and magnitude of such change has significantly increased due to anthropogenic causes. The rate at which a population spreads/contracts through space is a function of the rates of population growth and dispersal, coupled with density-dependence. Human-induced environmental changes can lead to variation in density-independent components of local birth or death rates through deterministic process (e.g. impoverishment/increase of habitat and food resources), thus pushing populations toward positive/negative growth. Moreover, spatial range constraints, such as dispersal, and density-dependence may also limit population growth and range expansion, beyond environmental characteristics. The main goal of this thesis is to explore the role played by ecological factors such as habitat and food availability, spatial range constraints and density-dependence in the expansion of a species through human-transformed environments. For this purpose, I use as a study model an expanding population of the marsh harrier living in an agricultural landscape of the Ebro Valley (northeastern peninsular Spain). Results obtained in this thesis suggest that environmental factors, sociability, dispersal constraints and density-dependent mechanisms may play an important role in the distribution of a species. Marsh harrier breeding numbers had been greatly reduced in previous decades (1960-1980) mainly due to organochlorine pesticides, drainage of wetlands and direct persecution. Thus, at least part of their increase in recent decades may represent population recovery following reductions in organochlorine use and direct persecution. However, the species may also have benefited from the spread of human-made structures such as artificial ponds and reservoirs related to agricultural intensification, for breeding and from their surrounding herbaceous crops for hunting. At a local scale, individual variation in density-dependence for productivity and settlement patterns may have favoured dispersal of some individuals to new empty habitat patches, while others aggregated around traditional areas. However, at a large scale (i.e., across peninsular Spain), the breeding population of marsh harriers seems to be spatially constricted beyond environmental variables. This result indicates that potential habitat for marsh harriers still exists for further expansions in the Iberian Peninsula (at least at the spatial resolution of our analyses, which does not allow us to consider smaller scale processes that may restrict the species distribution such as local food abundances or pesticides). Potential consequences of this expansion for other species should be considered in order to properly conserve biodiversity in a world of change.[cat] En aquesta tesi s’analitza el paper que desenvolupen factors ecològics com l’hàbitat i la disponibilitat d’aliments, les limitacions espacials i la denso-dependència en l’expansió d’una espècie en ambients transformats per l’home. S’utilitza com a model d’estudi l’arpella Circus aeruginosus en una zona agrícola de la Península Ibèrica, a la part oriental de la Vall de l’Ebre. Els resultats d’aquesta tesi indiquen que tant els factors ambientals, de sociabilitat, les limitacions dispersives i els mecanismes de denso-depèndecia poden jugar un paper important en la distribució d’una espècie. La població d’arpella s’havia reduït en dècades anteriors (1960-0980) degut principalment a l’assecament i contaminació de les zones humides on criava, a l’ús de pesticides i a la persecució directa per part de l’home. Si bé, part de l’augment que la població ha experimentat en els darrers anys podria ser degut a la recuperació de la seva població després de la reducció en l’ús d’organoclorats i en la seva persecució per part d l’home, l’espècie també s’hauria beneficiat en els darrers anys de l’increment d’estructures artificials, com embassaments i basses de reg artificials relacionades amb l’agricultura, e l’espècie utilitza per nidificar i dels cultius herbacis del voltant per caçar. A escala local, la variació individual en els efectes de la denso-dependència en la productivitat i patrons d’assentament, podrien haver afavorit la dispersió d’alguns individus a noves localitats buides, mentre altres individus amb una resposta diferent a la densitat s’agregaven al voltant de zones ja ocupades. A escala de la Península Ibèrica, l’àrea de distribució de l’arpella encara es veuria limitada, per factors espacials diferents al clima i al tipus d’hàbitat, indicant que encara hi hauria hàbitat potencial per a l’espècie (com a mínim a la resolució espacial de les nostres anàlisi, que no permeten considerar processos a escala local). Les possibles conseqüències de l’expansió d’aquesta i altres espècies haurien de ser considerades per tal de conservar adequadament la biodiversitat en l’actual escenari de canvi global
Social Identity and Navajo High School Students: Is a Strong Social Identity Important in the School Context?
No full textIn this paper, we explore the concept of identity. We do this by suggesting that one\u27s identity self-concept is multi-dimensional (personal, social, & cultural). Before examining the question in the title, we distinguish between these constructs. We then describe social identity theory and illustrate its utility by examining Navajo high school students\u27 positive and negative ability beliefs about school and how social identity theory might explain the results. We conclude by pointing to the need for more research in this important area of study, particularly in terms of the need for similar research with other cultural groups
Longitudinal analysis of serum neutralization of SARS-CoV-2 Omicron BA.2, BA.4, and BA.5 in patients receiving monoclonal antibodies
No full textThe emergence of Omicron sublineages impacts the therapeutic efficacy of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monoclonal antibodies (mAbs). Here, we evaluate neutralization and antibody-dependent cellular cytotoxicity (ADCC) activities of 6 therapeutic mAbs against Delta, BA.2, BA.4, and BA.5. The Omicron subvariants escape most antibodies but remain sensitive to bebtelovimab and cilgavimab. Consistent with their shared spike sequence, BA.4 and BA.5 display identical neutralization profiles. Sotrovimab is the most efficient at eliciting ADCC. We also analyze 121 sera from 40 immunocompromised individuals up to 6 months after infusion of Ronapreve (imdevimab + casirivimab) or Evusheld (cilgavimab + tixagevimab). Sera from Ronapreve-treated individuals do not neutralize Omicron subvariants. Evusheld-treated individuals neutralize BA.2 and BA.5, but titers are reduced. A longitudinal evaluation of sera from Evusheld-treated patients reveals a slow decay of mAb levels and neutralization, which is faster against BA.5. Our data shed light on antiviral activities of therapeutic mAbs and the duration of effectiveness of Evusheld pre-exposure prophylaxis
