Judean pithoi of Iron Age Eretz Israel

The excavation and analysis of pottery is an important element in the archaeology of Eretz Israel and in the development of assemblages which are representative of selected strata. The developments in ceramic research over the last century and a half have revealed that there are common characteristics among the pottery produced in a country in a single period of time. There are, however, decided differences between the pottery of various geographical regions. The character and history of the Southern Kingdom of Judah is reflective of the various geographical zones of the country through which the ubiquitous nature of ceramics provides a useful indicator of time periods and, to a degree, locales and consequently usage. This study has attempted, through statistical analysis to typologize pithoi according to dating periods and to isolate them as being predominantly from one particular area or another. Included also is an ethno-archaeological approach to pottery technology as a means to better understanding the character and role of the ceramics industry in light of the fragility and frequent replacement of pottery within a culture. This constant demand for new supplies allows for a relatively swift change in typoIogical development. Thus the typological advantages of pottery have firmly established it as the principal source of chronology for the historic and late prehistoric periods in Eretz Israel. In order to appreciate the circumstances in which the pithos developed the analysis takes into consideration the political and geographical environment of the Iron Age, ceramic traditions, the manner and means of manufacture of the pithos and also alternate means of storage. In light of these factors, as revealed at nineteen sites within four geographical zones, a number of pithos types are set forth as being representative of Judah in the Iron Age

Effective Instructional Strategies Utilized in Successful and High Performing Secondary Schools in the Southern Region of Mississippi

The schools in the United States have implemented measures intended to close the achievement gap for over fifty years (Solomon, 2009). The mandates handed down by the federal government cannot be altered. Therefore, schools are required to determine specific measures that increase student academic success. Prior research has demonstrated that schools can be successful if effective leadership at the district, school, and classroom level was present (Gregory, 2003; Johnson, Livingston, & Schwartz, 2000). At the classroom level, it was the leadership of the individual teacher to determine the creation of innovative techniques aimed at academic success of all students (Farr & Teach for America, 2010). The purpose of this quantitative study was to determine the effect that specific researched based instructional methods, assessments, and student learning methods had on student academic achievement as measured by school accountability rankings. The study included seven high performing and 15 successful secondary schools in south Mississippi that were located in districts that had a minimum of 70% of its student body that received free or reduced lunch. Data was collected using a purposeful, voluntary survey. Based upon the findings of this study, no significant differences were found in the instructional practices, assessments, or student learning methods utilized by the teachers at high poverty successful schools and high poverty, high performing schools. For this study, findings indicated that the teachers from the identified schools utilized research based instructional strategies such as practice on a specific skill, vocabulary, and checking for understanding. In addition, the findings indicated that the teachers used technology to aid in their instruction. Finally, the teachers noted the positive results in student achievement that resulted from being under the supervision of a visible effective principal. As an effective instructional leader, it is the principal who ultimately determined the culture for the school, and for a school to be successful that culture must be focused on teaching and learning

The use of jargon in education, 1920-1990

The Use of Jargon in Education: 1920-1990 provides a qualitative study based on communication theory was conducted on every issue of selected education journals at ten-year intervals from 1920 to 1990. Ninety preselected vocabulary words were the specific jargon terms evaluated in this study. Content analysis was the methodology for this study. The use of these terms was defined, quantified, tabulated, and graphed and similar terms and/or uses were identified. The ninety preselected vocabulary words were used 12,716 times for all five codes. Code 5 was deleted since it was for a different meaning than the one identified in this study. The jargon was used 5,399 times for codes 1 through 4 inclusive. Fourteen of the ninety jargon terms were not found in any issue of the sample. Nine of the jargon terms were found in only one journal in one decade. Only one of the preselected terms, ability grouping, was found in all decades and appeared 417 times as nineteen different terms/phrases with essentially constant context. The most prevalent jargon term, reform, appeared 809 times. The context of reform evolved from consolidation in the early decade to decentralization in the 1970\u27s differentiation and local empowerment in the 1980\u27s and 1990. No specific guidelines or criteria for reform were given in the literature. The use of jargon in education is a problem where it is not used consistently. This inconsistency limits how people within the profession communicate with each other and also how those professionals communicate with others

The effects of an integrated exercise and recreation therapy intervention on breast cancer survivors

Researchers investigated effects of a 20-week integrative intervention (IIG) assessing the physical and psychosocial health of breast cancer survivors. This retrospective study included 70 survivors randomized into 4 groups: IIG, exercise only (EX), recreation therapy only (RT), or control group (CO) and assessed at baseline, week 8, and post intervention. Three days a week the IIG exercised at low to moderate-intensity 60 minutes, and recreation therapy 30 minutes, EX did exercise only, RT did recreation therapy only and the control group, no intervention for the first 8 weeks. Following week 8 assessments, all groups received IIG intervention. Results revealed that the IIG promoted positive changes in cardiorespiratory function (p= .001), muscular fitness (p≤.0005), fatigue (p≤.0005), and quality of life (p= .001) within the first 8 weeks of a 20-week rehabilitation program. In conclusion, a combined exercise and psychosocial intervention promotes improvements in physiological and psychological needs of breast cancer survivors

The Imprinted Retrotransposon-Like Gene PEG11 (RTL1) Is Expressed as a Full-Length Protein in Skeletal Muscle from Callipyge Sheep

peer-reviewedMembers of the Ty3-Gypsy retrotransposon family are rare in mammalian genomes despite their abundance in invertebrates and some vertebrates. These elements contain a gag-pol-like structure characteristic of retroviruses but have lost their ability to retrotranspose into the mammalian genome and are thought to be inactive relics of ancient retrotransposition events. One of these retrotransposon-like elements, PEG11 (also called RTL1) is located at the distal end of ovine chromosome 18 within an imprinted gene cluster that is highly conserved in placental mammals. The region contains several conserved imprinted genes including BEGAIN, DLK1, DAT, GTL2 (MEG3), PEG11 (RTL1), PEG11as, MEG8, MIRG and DIO3. An intergenic point mutation between DLK1 and GTL2 causes muscle hypertrophy in callipyge sheep and is associated with large changes in expression of the genes linked in cis between DLK1 and MEG8. It has been suggested that over-expression of DLK1 is the effector of the callipyge phenotype; however, PEG11 gene expression is also strongly correlated with the emergence of the muscling phenotype as a function of genotype, muscle type and developmental stage. To date, there has been no direct evidence that PEG11 encodes a protein, especially as its anti-sense transcript (PEG11as) contains six miRNA that cause cleavage of the PEG11 transcript. Using immunological and mass spectrometry approaches we have directly identified the full-length PEG11 protein from postnatal nuclear preparations of callipyge skeletal muscle and conclude that its over-expression may be involved in inducing muscle hypertrophy. The developmental expression pattern of the PEG11 gene is consistent with the callipyge mutation causing recapitulation of the normal fetal-like gene expression program during postnatal development. Analysis of the PEG11 sequence indicates strong conservation of the regions encoding the antisense microRNA and in at least two cases these correspond with structural or functional domains of the protein suggesting co-evolution of the sense and antisense genes

Impacts of tidewater glacier advance on iceberg habitat

Icebergs in proglacial fjords serve as pupping, resting and molting habitat for some of the largest seasonal aggregations of harbor seals (Phoca vitulina richardii) in Alaska. One of the largest aggregations in Southeast Alaska occurs in Johns Hopkins Inlet, Glacier Bay National Park, where up to 2000 seals use icebergs produced by Johns Hopkins Glacier. Like other advancing tidewater glaciers, the advance of Johns Hopkins Glacier over the past century has been facilitated by the growth and continual redistribution of a submarine end moraine, which has limited mass losses from iceberg calving and submarine melting and enabled glacier thickening by providing flow resistance. A 15-year record of aerial surveys reveals (i) a decline in iceberg concentrations concurrent with moraine growth and (ii) that the iceberg size distributions can be approximated as power law distributions, with relatively little variability and no clear trends in the power law exponent despite large changes in ice fluxes over seasonal and interannual timescales. Together, these observations suggest that sustained tidewater glacier advance should typically be associated with reductions in the number of large, habitable icebergs, which may have implications for harbor seals relying on iceberg habitat for critical life-history events

First Measurement of A_N at sqrt(s)=200 GeV in Polarized Proton-Proton Elastic Scattering at RHIC

We report on the first measurement of the single spin analyzing power (A_N) at sqrt(s)=200GeV, obtained by the pp2pp experiment using polarized proton beams at the Relativistic Heavy Ion Collider (RHIC). Data points were measured in the four momentum transfer t range 0.01 < |t| < 0.03 (GeV/c)^2. Our result, averaged over the whole t-interval is about one standard deviation above the calculation, which uses interference between electromagnetic spin-flip amplitude and hadronic non-flip amplitude, the source of A_N. The difference could be explained by an additional contribution of a hadronic spin-flip amplitude to A_N.Comment: 13 pages, 5 figures. New values of polarization errors. Final version submitted to Phys. Lett.

First Measurement of Proton-Proton Elastic Scattering at RHIC

The first result of the pp2pp experiment at RHIC on elastic scattering of polarized protons at sqrt{s} = 200 GeV is reported here. The exponential slope parameter b of the diffractive peak of the elastic cross section in the t range 0.010 <= |t| <= 0.019 (GeV/c)^2 was measured to be b = 16.3 +- 1.6 (stat.) +- 0.9 (syst.) (GeV/c)^{-2} .Comment: 9 pages 5 figure
