Open Journal of Leadership (OJL) , 2013, DOI: 10.4236/ojl.2013.21002
Abstract: This study investigates the relationship between the leadership styles exhibited by almost 50% of the total population of public school principals (N= 651) in Lebanonand their attitudes and the level of use of technology for educational purposes in their schools. Datawerecollected by surveying school principals via two questionnaires. Moreover, one teacher from each participant public school (N=651) completed a questionnaire pertaining to the level of use of technology in the school. Findings suggest the existence of positive correlation between the autocratic leadership styles of school principals and their negative attitudes towards the use of ICT for educational purposes. In addition, the results of the study accentuate another positive correlation existing between principals’ attitudes towards the use of ICT for educational purposes and the level of its use by their teachers in schools. Recommendations for further research and implications for school leadership and training programs are provided.

Abstract: Justificación y objetivos: Entre las onicodistrofias, la onicomicosis es la afección más frecuente. Esta infección no solo representa un problema estético para el paciente, sino que puede afectar sus actividades diarias. Para el dermatólogo se hace indispensable realizar el diagnóstico diferencial, por lo que el laboratorio de micología médica es de gran ayuda para este propósito. En cuanto a los agentes etiológicos incriminados, los dermatofitos son los más frecuentes; sin embargo, otros hongos filamentosos no dermatofitos se han aislado, cuya sensibilidad a los antimicóticos es menor. En este trabajo se estudió la frecuencia de las onicomicosis diagnosticadas en el laboratorio de Micología Médica de la UCR durante cuatro a os, según edad y sexo de los pacientes, así como agentes etiológicos identificados. Métodos: Se incluyó a todos los pacientes que solicitaron el servicio de acción social que brinda la sección de Micología Médica, Facultad de Microbiología, Universidad de Costa Rica, entre enero del 2007 a diciembre del 2010 y que presentaban alteraciones ungueales sospechosas de onicomicosis. Se registró la edad y sexo de los pacientes y las muestras se procesaron por examen directo y cultivo. Resultados: Se procesaron 431 muestras de u as, el 85,4% eran de pie y el 14,6% de mano, la edad promedio de los pacientes fue de 49 a os, el 64% eran mujeres y el 36% eran hombres. En el 73,4% se diagnosticó onicomicosis, ya sea por examen directo positivo y cultivo positivo, o solo con el examen directo, de las cuales 89,4% eran u as de pie y 10,6% u as de manos. De las u as de los pies se aisló más frecuentemente Trichophyton rubrum y en segundo lugar Fusarium spp. En u as de manos C. albicans fue el agente etiológico más frecuente. Conclusión: En el diagnóstico de las onicomicosis se debe considerar tanto la clínica como los hallazgos de laboratorio. En la población estudiada se identificaron dermatofitos, levaduras y hongos filamentosos no dermatofitos, lo que es importante tener en cuenta por las implicaciones en la elección del tratamiento.

The Spin-Charge-Family Theory Is Explaining the Origin of Families, of the Higgs and the Yukawa Couplings  [PDF]

Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.46113
Abstract:

The (extremely efficient) standard model of the elementary particles and fields makes several assumptions, which call for explanations. Any theory offering next step beyond the standard model must explain at least the existence and properties of families and their members and correspondingly the existence of the scalar Higgs and the Yukawa couplings, which in this model take care of masses of fermions and weak bosons and influence the decaying properties of families. The spin-charge-family theory [1-11] is offering a possible explanation for the assumptions of the standard model—for the appearance of families and their members (for the charges of a family members), for the gauge fields, for the scalar fields—interpreting the standard model as its low energy effective manifestation. The spin-charge-family theory predicts at the low energy regime two decoupled groups of four families of quarks and leptons. The predicted fourth family waits to be observed, while the stable fifth family is the candidate to form the dark matter. In this paper properties of families are analysed. The appearance of several scalar fields, all in the bosonic (adjoint) representations with respect to the family groups, while they are doublets with respect to the weak charge, is presented, their properties discussed, it is explained how these scalar fields can effectively be interpreted as the standard model Higgs and the Yukawa couplings. The spin-charge-family

Abstract: The spin-charge-family theory is a kind of the Kaluza-Klein theories, but with two kinds of the spin connection fields, which are the gauge fields of the two kinds of spins. The SO(13,1) representation of one kind of spins manifests in d = (3 + 1) all the properties of family members as assumed by the standard model; the second kind of spins explains the appearance of families. The gauge fields of the first kind, carrying the space index m = (0,...,3), manifest in d = (3 + 1) all the vector gauge fields assumed by the standard model. The gauge fields of both kinds of spins, which carry the space index (7, 8) gaining at the electroweak break nonzero vacuum expectation values, manifest in d = (3 + 1) as scalar fields with the properties of the Higgs scalar of the standard model with respect to the weak and the hyper charge (\"\" and \"\", respectively), while they carry additional quantum numbers in adjoint representations, offering correspondingly the explanation for the scalar Higgs and the Yukawa couplings, predicting the fourth family and the existence of several scalar fields. The paper 1) explains why in this theory the gauge fields are with the scalar index s = (5,6,7,8) doublets with respect to the weak and the hyper charge, while they are with respect to all the other charges in the adjoint representations; 2) demonstrates that the spin connection fields manifest as the Kaluza-Klein vector gauge fields, which arise from the vielbeins; and 3) explains the role of the vielbeins and of both kinds of the spin connection fields.

Case Reports in Pediatrics , 2011, DOI: 10.1155/2011/307857
Abstract: The recurrence of cerebral palsy in the same family is uncommon. We, however, report on two families with two or more affected siblings. In both families, numerous potential risk factors were identified including environmental, obstetric, and possible maternal effects. We hypothesize that multiple risk factors may lead to the increased risk of recurrence of cerebral palsy in families. Intrinsic and maternal risk factors should be investigated in all cases of cerebral palsy to properly counsel families on the risk of recurrence. Recent studies of genetic polymorphisms associated with cerebral palsy are considered with reference to our observations in these two families.

Abstract: Objective. We investigated the use of miconazole among female prostitutes in Costa Rica as well as the distribution of vaginal yeasts and the susceptibility pattern to azoles of strains obtained from this population. Our intention was to relate a frequent use of miconazole to occurrence of vaginal yeasts resistant to azoles. Methods. Vaginal samples were taken from 277 patients that have previously used azoles. Vaginal swabs were obtained for direct microscopy and culture. Yeast isolates were identified by germ tube test and assimilation pattern. Susceptibility testing was determined using a tablet diffusion method. Results. The number of clinical Candida isolates (one from each patient) was 57 (20.6%). C. albicans was the predominant species (70%), followed by C. parapsilosis (12%), C. tropicalis (5.3%), C. glabrata and C. famata (3.5% each), C. krusei, C. inconspicua and C. guilliermondii (1.7% each). The majority of vaginal Candida isolates were susceptible to ketoconazole (91%), fluconazole (96.5%), and itraconazole (98%). A lower susceptibility of some isolates to miconazole (63%) was observed as compared to the other azoles tested. Moreover, the strains, nonsusceptible to miconazole, were more often obtained from patients that have used this antifungal at least four times within the last year before taking the samples as compared to those with three or less treatments (P<.01). Conclusion. An indiscriminate use of miconazole, such as that observed among female prostitutes in Costa Rica, results in a reduced susceptibility of vaginal yeasts to miconazole but not to other azoles.

Malaria Journal , 2007, DOI: 10.1186/1475-2875-6-101
Abstract: To test the efficacy of the repellent, field trials were staged in Guatemala and Peru. Repellent efficacy was determined by human-landing catches on volunteers who wore the experimental repellents, control, or 15% DEET. The studies were conducted using a balanced Latin Square design with volunteers, treatments, and locations rotated each night.In Guatemala, collections were performed for two hours, commencing three hours after repellent application. The repellent provided >98% protection for five hours after application, with a biting pressure of >100 landings per person/hour. The 15% DEET control provided lower protection at 92% (p < 0.0001). In Peru, collections were performed for four hours, commencing two hours after repellent application. The PMD/LG repellent provided 95% protection for six hours after application with a biting pressure of >46 landings per person/hour. The 20% DEET control provided significantly lower protection at 64% (p < 0.0001).In both locations, the PMD/LG repellent provided excellent protection up to six hours after application against a wide range of disease vectors including Anopheles darlingi. The addition of fixatives to the repellent extended its longevity while enhancing efficacy and significantly reducing its cost to malaria-endemic communities.In 2005, the WHO reported that 41% of malaria cases occur outside of Africa [1]. This marked a significant increase over their 2001 estimate of 13.6% [2] and reflects a growing awareness of the malaria problem beyond Africa. Greater recognition of this should encourage increased research on malaria vector control in other areas of the globe, an important consideration, as vectors in these regions generally exhibit behavior patterns that make them less susceptible to control measures shown to be effective in Africa, such as insecticide treated bednets (ITNs) and indoor residual spraying (IRS).These behaviors include tendencies to [i] outdoor resting e.g. Anopheles darlingi [3] and Anopheles d
