A survey was conducted using standard parasitological procedures to determine the ecology of ticks on the cattle within the main campus of the University of Abuja, Nigeria. The tick specie identified were Amblyomma variegatum, Amblyomma hebraeum, 0rnithodorus moubata complex, Hyalomma truncatum, Hyalomma rufipies, Rhipicephalus decoloratus, Phipicephalus appendiculatus, and Boophilus microplus. Of the 100 cattle examined. 47(47%) of the tick examined was found on the male cow and 53(53%) were found on the female cow. In addition, 23(23%) of the observed tick are found on the leg, 20(20%) are found in the anus, 20(20%) are found on the udder, 14(14%) are found on the back while 23(23%) of the ticks are found in the ear. 31(31%) of the observed ticks were found on the bunaj specie, 24(24%) of the ticks on the Gudali, 24(24%) of the observed ticks on the Rahaji specie and 21(21%) on the wadara specie. Amblyomma hebraeum, Ornithodorus moubata Complex and Rhipicephalus dicoloratus were found more dominantly on Bunaj breed (42.9%, 55.6% and 42.9% respectively), Amblyomma variegatum and Phipicephalus appendiculatus was observed to be more dominant on Rahaji breed (infesting 33.3% and 66.7% respectively), Boophylus microplus and Hyalomma rufipe were found dominant on wadara (30% and 50% respectively). There is need to help establish baseline information on ticks ecology and occurrence in the study area which would consequently lead to increased public awareness especially to the herdsmen and in avoiding tick borne diseases, also to help in vector control formulation and to prevent the herdsmen of suffering from low productivity due to the presence of ticks, thereby leading to various weaknesses, diseases and sometimes death of the cattle. Owing to this, this study did not only identify the tick species infesting cattle but also examined the host-parasite ecology of ticks on cattle within the main campus of the University of Abuja, Nigeria.

With the success and popularity of vehicle navigation services, the demand for Pedestrian Navigation Services (PNS) has increased in recent years. PNS, while overlap in functionality with vehicle navigation services, must be designed specifically for the wayfinding and navigational needs and preferences of pedestrians. One major shortcoming of most existing PNS in outdoors is that they utilize and provide services based on road networks, resulting in PNS that do not effectively and properly track pedestrians as they usually walk on sidewalks, which have more segments and are narrower than roads. Challenges in building PNS include constructing appropriate sidewalk networks, continually tracking users in real time on sidewalks without interruption, and providing personalized routes as well as directions. In this paper, these challenges are highlighted and current trends in PNS, for both outdoors and indoors, are discussed and analyzed. A prototype PNS designed for the University of Pittsburg’s main campus sidewalk network (PNS-Pitt) is also discussed.

The University of British Columbia-Vancouver (UBC-V) implemented a campus-wide survey of faculty teaching practices and perceptions. All 11 Faculties participated, resulting in a total of 1177 responses for an overall response rate of 24%. We compared response patterns of faculty who reported spending less than 25%, between 26-50%, between 51-75%, and more than 75% of classroom time lecturing. Using this breakdown, we analysed survey responses related to in and out-of-class practices and expectations for students, use of teaching assistant time, participation in professional development opportunities, and perceptions of whether the institution valued teaching. Participants across quadrants reported employing a wide range of teaching methods irrespective of years of experience and class size. Our findings outline the range of teaching practices employed by faculty at a large research-intensive Canadian institution and may provide baseline information for institutions of similar scale and focus.

The Australian Twin Registry (ATR) is a national volunteer resource of twin pairs and higher-order multiples willing to consider participating in health, medical, and scientific research. The vision of the ATR is ‘to realize the full potential of research involving twins to improve the health and well-being of all Australians’. The ATR has been funded continuously by the National Health and Medical Council for more than 30 years. Its core functions entail the recruitment and retention of twin members, the maintenance of an up-to-date database containing members’ contact details and baseline information, and the promotion and provision of open access to researchers from all institutes in Australia, and their collaborators, in a fair and equitable manner. The ATR is administered by The University of Melbourne, which acts as custodian. Since the late 1970s the ATR has enrolled more than 40,000 twin pairs of all zygosities and facilitated more than 500 studies that have produced at least 700 peer-reviewed publications from classical twin studies, co-twin control studies, within-pair comparisons, twin family studies, longitudinal twin studies, randomized controlled trials, and epigenetics studies, as well as studies of issues specific to twins. New initiatives include: a Health and Life Style Questionnaire; data collection, management, and archiving using a secure online software program (The Ark); and the International Network of Twin Registries. The ATR's expertise and 30 years of experience in providing services to national and international twin studies has made it an important resource for research across a broad range of disciplines.

This study compares the prevalence of ixodid tick species on cattle and goats in Maputo Province. Adult ticks as well as the nymphs of three species, and only the adults of two species were collected from sets of five cattle at 21 localities throughout the province and compared with those collected from similar sets of goats at the same places. Amblyomma hebraeum adults and / or nymphs were present on cattle and on goats at all 21 localities, and 90 cattle and 22 goats were infested with adult ticks. Rhipicephalus (Boophilus) microplus adults and / or nymphs were collected from cattle at 20 and from goats at 15 localities, and 92 cattle and 34 goats were infested [Chi-square test (×2), P < 0.001]. The total length of several maturing female R. (Boophilus) microplus collected from cattle and goats exceeded 5 mm, indicating that they successfully engorge on both host species. Rhipicephalus appendiculatus adults and / or nymphs were present on cattle at 15 and on goats at 13 localities, but 28 cattle and only one goat were infested with adult ticks (×2, P < 0.001). Adult Rhipicephalus evertsi evertsi were recovered from cattle at 20 and from goats at 17 localities, and 74 cattle and 69 goats were infested. Adult Rhipicephalus simus were collected from cattle at 18 and from goats at 11 localities (Fisher's exact test, P = 0.04), and 60 cattle and 14 goats were infested (×2, P < 0.001). These findings underscore the advisability of including goats in acaricide application programmes designed for the control of tick-borne diseases in cattle at the same locality.

The development of the feeding lesions of the ixodid tick Boophilus microplus was followed throughout the parasitic life-cycle on cattle of both Zebu and European breeds, using histological techniques.The feeding lesion of this tick must be the result of an interaction between the tick and its host as it is neither the result of simple mechanical trauma, nor of lysis of the host tissues by salivary secretions of the tick alone, nor is it solely a result of an inflammatory response.The histological evidence suggests that the diet of the tick in each instar changes as the lesion develops; first, tissue fluids are available, then tissue fluids along with leucocytes which have infiltrated the lesion, and finally these two components along with whole blood.An early intense infiltration of eosinophils into the area of the mouthparts, typical of an immediate hypersensitive or anaphylactic response, was noted with European cattle on secondary and subsequent exposures to larvae. Hypersensitivity to tick infestation, which has been equated with resistance to infestation, was seen as an extreme of a normal spectrum of sensitization which results in an abnormal susceptibility.The definitive lesion was similar with all hosts studied. It consisted of a cavity containing leucocytes, predominantly neutrophils, some lymphocytes and erythrocytes in an area of heavily infiltrated collagen.It is concluded that this host-parasite relationship illustrates the concept of adaptation tolerance as proposed by Sprent (1962).It is with much pleasure that we acknowledge the continued generous financial support by the Australian Meat Research Committee (formerly the Australian Cattle and Beef Research Committee), which has made possible this project.

Academic And Social Experiences

<p>This qualitative study aimed to present baseline information about the academic and social experiences of the foreign students at the University of the Immaculate Conception (UIC). The researchers conducted a focus group discussion involving 15 of them who are currently enrolled in various programs of the university. Through an in-depth interview, it was found that most of the foreign students have known UIC via a recommendation of a friend, or the internet. Findings revealed that the existence of the foreign students in UIC is characterized both by pleasant and unpleasant experiences. The positive feedback about the UIC educational system opens a possibility for more influx of foreign students while the unpleasant experiences pose dramatic amendments in established policies of the university.</p>

<p>The  study  aimed  to  establish  baseline  information  on  the  influence  of research capability and culture on the passion for research; whether or not such influence is significant. It utilized quantitative method via descriptive correlational and analytical designs with the use of statistical tools such as Weighted Mean, Pearson r and Multiple Linear Regressions. The study reports the following: the overall level of the respondents’ research capability is average; the overall level of the respondents’ research culture is average; the overall level of the respondents’ passion for research is high; the respondents’ research capability significantly related to their passion for research; there is a significant relationship between the respondents’ research culture and their passion for research; the respondents’ capability and culture on research are significant factors to their passion for research (F=19.40; p&lt;0.05). Hence, the study inferred that any change on the level of the respondents’ research capability and culture has a corresponding effect on the level of their passion for research. Furthermore, the combined influence of 37.40% implies that 62.60% are influenced by other factors not covered in this study.</p>
