People watching : a case study of teacher observation culture and social learning spaces in Dubai private schools
No full textStudent enrolment and fee revenue in international private schools are at an all-time high around the world. Private international schools in Dubai are among the highest in volume and most competitive in this global market. As a result of this, teacher accountability and observation culture has become the norm. Recent studies report teacher frustration with many of these formal observation systems and question their impact on continued teacher professional development. As many international schools operate as social learning spaces within which informal professional development often takes place between teachers, this study aims to understand the impact that formal teacher observation culture has on social learning. The study was designed with a mixed-method approach, using quantitative survey data to gain an overview of the observation culture in Dubai, combined with informal interviews to understand the lived experience of these teachers.
The results from the study substantiated the existence of this formal observation culture with many teachers reporting regular formal visits from Senior Leadership and variations in feedback from informal discussion to pay related judgments and ratings. This practice was often completed in preparation for visits by the KHDA, the regulating body responsible for the annual inspection of Dubai private schools. The study also confirmed that these schools operate as social learning spaces within which teachers contribute to mutual professional development in a variety of informal social practices. The formal observation systems adopted by the schools often had an impact on some of the key elements in social learning spaces such as staff relationships.
There is substantial evidence to suggest that schools need to rethink their approach to teacher observation to correct what has become a stressful and toxic observation culture in the Dubai private school industry. As evidence has shown that teachers often place more value on informal social learning from their peers, more opportunities should be put in place to allow these to foster with less emphasis placed on pre-planned, artificial lesson observations in preparation for the annual school inspection

David Zimmer Christmas letter
No full textThis Christmas letter written November 30, 1999, by David Zimmer is titled "Season's Greetings from the last of the Red-Hot-Santas!" It features an illustration of Santa Claus with a guitar, and a summary of Zimmer's year.
David Zimmer (1929-2005) was born in Harrisburg, Ohio. He enlisted in the U.S. Army and served for two years during the Korean War at the Brooke Army Medical Center in San Antonio, where he performed in drag for wounded soldiers. After the war, he returned to Ohio. Zimmer performed as Dolly Divine, a name inspired by the song "Hello Dolly." In 1964, he established the Berwick Ball with Orn Huntington, another important early gay activist in Central Ohio. The Ball began as a formal Halloween costume ball that provided a safe space to gather and enjoy drag shows for the gay community each year; over the years, it grew into an annual Halloween tradition and an important fundraiser for the AIDS movement and other charities. During the 1970s, Zimmer was also known for hosting lavish parties at his Harrisburg home. In 1989, he moved to the German Village area of Columbus where he remained active in the community. During the 1990s, Zimmer continued to perform in and out of drag and commissioned costume designer Dick Frank to make elaborate outfits. Zimmer worked for Huntington National Bank for 39 years and was a member of the Harrisburg United Methodist Church, Veterans of Foreign Wars and the German Village Society

The identification of, and studies on, a FMRF-NH2-related peptide from the nematode Haemonchus contortus
No full textIndirect immunocytochemistry was used to identify neurones in Haemonchus contortus that exhibited immunoreactivity to the polyclonal antisera KYSALMFamide (code: BL). It was possible to identify major neurones in the central and motor nervous system of H.contortus that showed BL-like immunoreactivity (SLI), and this pattern of immunoreactivity was also obtained in Ascaris suum. Preabsorption of BL(IV) using FMRFamide-related peptides (FaRPs) abolished SLI in H.contortus in the following decreasing order of potency; AF2>AF1=FLRFamide>FMRFamide. These studies provided evidence that the BL antisera was detecting FaRP-like epitopes in the nervous system of this parasite that had some structural homology to AF2.BL antisera was used in a standard radioimmunoassay, and was found to cross react preferentially with FaRPs terminating in Leu-Arg-Phe-NH2. The antisera was subsequently used in a RIA to monitor purification of FaRPs from acid: methanol extracts of H.contortus using reverse phase high performance liquid chromatography. Six areas of SLI were resolved and one FaRP was isolated. It was unequivocally identified as AF2 (KHEYLRFamide). A second non-immunoreactive peptide, QPIEYTYIamide was also identified.The role of AF2 in the nervous system of nematodes was investigated using A.suum as a model organism. It was found that AF2 potentiated the contractions elicited by acetylcholine (ACh) on Ascaris muscle strips by 140±22% and increased the Emax of a concentration-response curve to ACh to 114±6% of the control response. AF2 also increased the relaxation rate of ACh elicited contractions from 0.19±0.04 g. sec-1 in the absence of AF2 to 0.45±0.14 g. sec-1 in the presence of the peptide, an increase of 236%.It is suggested that one action of AF2 is to increase the rate and strength of nematode muscular contractions by modulating the effect of an endogenous neurotransmitter, and that this modulation may be linked to the peptide inhibiting cAMP, or potentiating the protein kinase C pathways.</p
