TEACHER EFFICACY, JOB SATISFACTION, AND ALTERNATIVE CERTIFICATION IN EARLY CAREER SPECIAL EDUCATION TEACHERS
The number of special education students continues to rise, creating the need for additional special education teachers. Alternative certification programs have dealt with the special education teacher shortage, but not the question of teacher quality. Most teachers entering classrooms from alternative certification programs have little or no formal education in methodology or behavior management, but have commensurate responsibilities as their more experienced colleagues.
The intent of this quantitative study was to examine 222 special education teachers’ sense of self-efficacy and job satisfaction in 21 central Kentucky school districts. The focus was the relation among special education teacher’s degree of efficacy in the early years of their careers (zero to five), degree of job satisfaction, and their certification type in special education (alternative vs. traditional).
The secondary purpose was to examine the interrelation among teacher efficacy, number of years in the profession, degree of job satisfaction, gender, type of classroom, and area of certification in special education. The degree of teacher self-efficacy is linked to increased student outcomes and achievement, extent of planning, implementation of new ideas, enthusiasm, commitment, and increased patience with struggling students.
The Teacher Sense of Efficacy Scale was utilized to measure teacher efficacy. The Brayfield Rothe Job Satisfaction Index (1951) as modified by Warner (1973) was employed to measure the affective factors of job satisfaction. A demographic questionnaire developed by the researcher gathered information from the respondents.
The study hypothesis assumed that teacher efficacy, specifically teacher self-efficacy, was lower in early career special education teachers who were pursuing or had recently completed certification through alternative programs. Analysis of the data indicates there is no significant difference between special education teachers who have completed alternative certification programs and their traditionally certified counterparts in terms of their degree of self-efficacy. Responses from the Job Satisfaction Survey indicated both groups of special education teachers are satisfied with their jobs
Dancing with dirt and wires; reconciling the embodied and the digital in site responsive collaborative practice
Acknowledging the practitioner-researcher model and collaboration inherent to twenty-first-century contemporary performance practices, this co- authored chapter is offered as an extension of an ongoing collaboration between two dance artists and a photographer working in outdoor performance under the project enter & inhabit. The writing process and resulting chapter moves between a reflection on process, a document of practice and a theorisation around live and digital composition, thus inviting a reconsideration of the relationship between the real and the virtual
everything is at once: Reflections on embodied photography and collaborative process
In discussion with his co-collaborators, dance artists Natalie Garrett Brown and Amy Voris, this interview explores the photographic process of Christian Kipp, landscape and dance photographer, as he reflects on his experience of working on the Enter & Inhabit project. The questions asked by Garrett Brown and Voris were generated through movement and reflective writing in response to the photographic collection exhibited as part of the 2011 Dance and Somatic Practices Conference, Coventry, UK. In particular, the article explores the interrelationship between the somatic-informed movement practices and performance score creation of Garrett Brown and Voris and the sensorial play of Kipp’s photography. Co-authored by Garrett Brown, Kipp and Voris, this collection of questions and responses seeks to continue rather than merely document the Enter & Inhabit collaborative process

Recent Developments: The Uniform Arbitration Act
Since 1983, this annual Article 2 has been prepared to provide a survey of recent developments in the case law interpreting and applying the various state versions of the Uniform Arbitration Act3. The purpose is to promote uniformity in the interpretation of the U.A.A. by developing and explaining the underlying principles and rationales courts have applied in recent cases.
A novel widespread cryptic species and phylogeographic patterns within several giant clam species (Cardiidae: Tridacna) from the Indo-Pacific Ocean
Giant clams (genus Tridacna) are iconic coral reef animals of the Indian and Pacific Oceans, easily recognizable by their massive shells and vibrantly colored mantle tissue. Most Tridacna species are listed by CITES and the IUCN Redlist, as their populations have been extensively harvested and depleted in many regions. Here, we survey Tridacna crocea and Tridacna maxima from the eastern Indian and western Pacific Oceans for mitochondrial (COI and 16S) and nuclear (ITS) sequence variation and consolidate these data with previous published results using phylogenetic analyses. We find deep intraspecific differentiation within both T. crocea and T. maxima. In T. crocea we describe a previously undocumented phylogeographic division to the east of Cenderawasih Bay (northwest New Guinea), whereas for T. maxima the previously described, distinctive lineage of Cenderawasih Bay can be seen to also typify western Pacific populations. Furthermore, we find an undescribed, monophyletic group that is evolutionarily distinct from named Tridacna species at both mitochondrial and nuclear loci. This cryptic taxon is geographically widespread with a range extent that minimally includes much of the central Indo-Pacific region. Our results reinforce the emerging paradigm that cryptic species are common among marine invertebrates, even for conspicuous and culturally significant taxa. Additionally, our results add to identified locations of genetic differentiation across the central Indo-Pacific and highlight how phylogeographic patterns may differ even between closely related and co-distributed species
Meningococcal, influenza virus, and hepatitis B virus vaccination coverage level among health care workers in Hajj
Abstract Background The objective of this study was to assess the compliance of health care workers (HCWs) employed in Hajj in receiving the meningococcal, influenza, and hepatitis B vaccines. Methods A cross-sectional survey of doctors and nurses working in all Mena and Arafat hospitals and primary health care centers who attended Hajj-medicine training programs immediately before the beginning of Hajj of the lunar Islamic year 1423 (2003) using self-administered structured questionnaire which included demographic data and data on vaccination history. Results A total of 392 HCWs were studied including 215 (54.8%) nurses and 177 (45.2%) doctors. One hundred and sixty four (41.8%) HCWs were from Makkah and the rest were recruited from other regions in Saudi Arabia. Three hundred and twenty three (82.4%) HCWs received the quadrivalent (ACYW135) meningococcal meningitis vaccine with 271 (83.9%) HCWs receiving it at least 2 weeks before coming to Hajj, whereas the remaining 52 (16.1%) HCWs received it within Conclusion The meningococcal and hepatitis B vaccination coverage level among HCWs in Hajj was suboptimal and the influenza vaccination level was notably low. Strategies to improve vaccination coverage among HCWs should be adopted by all health care facilities in Saudi Arabia.</p
Plasmodium knowlesi: Reservoir Hosts and Tracking the Emergence in Humans and Macaques
Plasmodium knowlesi, a malaria parasite originally thought to be restricted to macaques in Southeast Asia, has recently been recognized as a significant cause of human malaria. Unlike the benign and morphologically similar P. malariae, these parasites can lead to fatal infections. Malaria parasites, including P. knowlesi, have not yet been detected in macaques of the Kapit Division of Malaysian Borneo, where the majority of human knowlesi malaria cases have been reported. In order to extend our understanding of the epidemiology and evolutionary history of P. knowlesi, we examined 108 wild macaques for malaria parasites and sequenced the circumsporozoite protein (csp) gene and mitochondrial (mt) DNA of P. knowlesi isolates derived from macaques and humans. We detected five species of Plasmodium (P. knowlesi, P. inui, P. cynomolgi, P. fieldi and P. coatneyi) in the long-tailed and pig-tailed macaques, and an extremely high prevalence of P. inui and P. knowlesi. Macaques had a higher number of P. knowlesi genotypes per infection than humans, and some diverse alleles of the P. knowlesi csp gene and certain mtDNA haplotypes were shared between both hosts. Analyses of DNA sequence data indicate that there are no mtDNA lineages associated exclusively with either host. Furthermore, our analyses of the mtDNA data reveal that P. knowlesi is derived from an ancestral parasite population that existed prior to human settlement in Southeast Asia, and underwent significant population expansion approximately 30,000–40,000 years ago. Our results indicate that human infections with P. knowlesi are not newly emergent in Southeast Asia and that knowlesi malaria is primarily a zoonosis with wild macaques as the reservoir hosts. However, ongoing ecological changes resulting from deforestation, with an associated increase in the human population, could enable this pathogenic species of Plasmodium to switch to humans as the preferred host
Evolutionary relationships and divergence times among the native rats of Australia
Background The genus Rattus is highly speciose and has a complex taxonomy that is not fully resolved. As shown previously there are two major groups within the genus, an Asian and an Australo-Papuan group. This study focuses on the Australo-Papuan group and particularly on the Australian rats. There are uncertainties regarding the number of species within the group and the relationships among them. We analysed 16 mitochondrial genomes, including seven novel genomes from six species, to help elucidate the evolutionary history of the Australian rats. We also demonstrate, from a larger dataset, the usefulness of short regions of the mitochondrial genome in identifying these rats at the species level. Results Analyses of 16 mitochondrial genomes representing species sampled from Australo-Papuan and Asian clades of Rattus indicate divergence of these two groups ~2.7 million years ago (Mya). Subsequent diversification of at least 4 lineages within the Australo-Papuan clade was rapid and occurred over the period from ~ 0.9-1.7 Mya, a finding that explains the difficulty in resolving some relationships within this clade. Phylogenetic analyses of our 126 taxon, but shorter sequence (1952 nucleotides long), Rattus database generally give well supported species clades. Conclusions Our whole mitochondrial genome analyses are concordant with a taxonomic division that places the native Australian rats into the Rattus fuscipes species group. We suggest the following order of divergence of the Australian species. R. fuscipes is the oldest lineage among the Australian rats and is not part of a New Guinean radiation. R. lutreolus is also within this Australian clade and shallower than R. tunneyi while the R. sordidus group is the shallowest lineage in the clade. The divergences within the R. sordidus and R. leucopus lineages occurring about half a million years ago support the hypotheses of more recent interchanges of rats between Australia and New Guinea. While problematic for inference of deeper divergences, we report that the analysis of shorter mitochondrial sequences is very useful for species identification in rats
Evolution in Australasian Mangrove Forests: Multilocus Phylogenetic Analysis of the Gerygone Warblers (Aves: Acanthizidae)
The mangrove forests of Australasia have many endemic bird species but their
evolution and radiation in those habitats has been little studied. One genus
with several mangrove specialist species is Gerygone
(Passeriformes: Acanthizidae). The phylogeny of the Acanthizidae is reasonably
well understood but limited taxon sampling for Gerygone has
constrained understanding of its evolution and historical biogeography in
mangroves. Here we report on a phylogenetic analysis of
Gerygone based on comprehensive taxon sampling and a
multilocus dataset of thirteen loci spread across the avian genome (eleven
nuclear and two mitochondrial loci). Since Gerygone includes
three species restricted to Australia's coastal mangrove forests, we
particularly sought to understand the biogeography of their evolution in that
ecosystem. Analyses of individual loci, as well as of a concatenated dataset
drawn from previous molecular studies indicates that the genus as currently
defined is not monophyletic, and that the Grey Gerygone (G.
cinerea) from New Guinea should be transferred to the genus
Acanthiza. The multilocus approach has permitted the
nuanced view of the group's evolution into mangrove ecosystems having
occurred on multiple occasions, in three non-overlapping time frames, most
likely first by the G. magnirostris lineage, and subsequently
followed by those of G. tenebrosa and G.
levigaster
