Emancipatory education for Palestine: the power of teacher leadership

This paper arises from the author’s doctoral studies in educational leadership at the University of Cambridge under the supervision of Dr David Frost. It provides an account of the introduction of the non-positional approach to teacher leadership as a vehicle for emancipatory education in her school in Ramallah, Palestine. The paper analyses the way in which the author has adopted the UK-based, and internationally embraced, teacher-led development work (TLDW) framework, and adapted it to the local socio-cultural and educational context. Through this teachers have been enabled to develop practice and build local knowledge for improved student outcomes. The TLDW methods and tools have enabled the development of emancipatory pedagogic features among teachers and staff that include collaboration, dialogue, reflection and action for change. Interim results indicate enhanced agency, empowerment and transformation among programme participants. The paper concludes with an outline of the practical implications for professional development, organisational change and policymaking. The case is made for a locally relevant, problem-based and cost-effective educational change strategy that is favourable to such disadvantaged and under-resourced educational settings.
Phenolic Content and Antimicrobial activities of Date Palm (Phoenix dactylifera L.) Fruits and Leaves

This study aimed to investigate total phenolic content (TPC) and antibacterial activities of different extracts recovered from Date Palm fruit and leaves using various solvents, including methanol, ethanol and water. The results showed that the highest phenolic content was found in Leaf Methanol extract, followed by Leaf Ethanol extract, and then followed by Seed Methanol extract (74.4 mg/g, 67.3 mg/g, and 64.7 mg/g respectively). Whereas, the date methanol extract had the lowest phenolic content (5 mg/g). The study was also scrutinized to find the antibacterial inhibitory property in the leaves and fruits of date palm against four bacterial species ( E.coli , Staphylococcus aureus , Bacillus subtilis , and Pseudomonas aeruginosa ) by using the well diffusion method and minimum inhibitory concentration (MIC). Date leaves extracts showed inhibitory effect on the growth of Staphylococcus aureu s and Bacillus subtilis and resistance to Pseudomonas aeruginosa and E.coli . MIC of methanol and ethanol (70%) leaves extract were 100 mg/ml and 250mg/ml for S. aureus and B. subtilis respectively, however, all the bacteria have resistance to date fruits extracts.
Effect of Citrullus colocynthis (Cucurbitaceae) agglutinin on the life table parameters of Apomyelois ceratoniae (Lepidoptera: Pyralidae)

A Castanea crenata agglutinin (abbreviated as CCA) was extracted and purified from bitter apple, Citrullus colocynthis L. , to determine its effects on the demographic parameters of Apomyelois ceratoniae Zeller. Two groups of first larval instars were reared on an artificial diet containing 2% (w/w) of CCA and control diets until emergence of adults. Two Sex MS-chart life table software was used to analyze data and calculate life table parameters. Developmental times of larvae in control and CCA diets showed statistical differences for male, female except for third and fourth larval instars. It was found that A. ceratoniae larvae fed on control had a survival of 18 days but individuals fed on CCA diet survived for 12 days. The highest fecundity values of individuals fed on control and CCA diets were obtained at the age of 30 and 27 days, respectively. Adult longevity, pre-oviposition period, oviposition period and mean fecundity of A. ceratoniae fed on control were higher than those of individuals fed on CCA diet. The probabilities of a newborn egg surviving to age 28 days were 0.42 and 0.3 for control and CCA, respectively. Each female started egg laying on day 22 for control and 25 for CCA. Life expectancies of a newly laid egg were 29 days for control and 26 days for CCA treatment. Life table parameters except for mean generation time showed statistical differences between control and CCA treatments. These results demonstrated the negative effects of CCA on life table parameters of A. ceratoniae that might lead to a promising and alternative way to suppress population increase and damage caused by A. ceratoniae.
A set-cover-based approach for inexact graph matching

Network querying is a growing domain with vast applications ranging from screening compounds against a database of known molecules to matching subnetworks across species. Graph indexing is a powerful method for searching for queries in a large database of graphs. Most graph indexing methods to date tackle the exact matching (isomorphism) problem, limiting their applicability to specific instances in which such matches exist. Here we provide a novel graph indexing method to cope with the more general, inexact matching problem. Our method, SIGMA, builds on approximating a new variant of the set-cover problem that concerns overlapping multi-sets. We extensively test our method and compare it to a layman approach and to the state-of-the-art Grafil. We show that SIGMA outperforms both, providing higher pruning power in all the tested scenarios.
Do You Have A Friend ? : The Impact Of Personal Knowledge Of Someone With Aids On Attitudes Towards Aids 2004

The study of attitudes towards those with AIDS is relatively recent. Most studies have examined attitudes concerning health and medical concerns. Little research has focused on attitudes toward social and behavior concerns. The few that have focused on such attitudes have employed relatively small samples collected primarily out of convenience. The studies that have used national samples have primarily addressed public policy issues. Using national data from the 1988 General Social Survey, this paper examines the effects of personal knowledge about the AIDS virus and other attitudinal variables on four dimensions of social and behavioral concern for those with AIDS in American society. Sociodemographic variables, which prior studies have demonstrated as important predictors of attitudes toward AIDS, are included as controls in this research that presents findings from a multivariate analysis. Results suggests that the impact of personal knowledge of someone with AIDS does not strongly lead to more supportive attitudes regarding the rights of people with AIDS, except when the economic costs of AIDS care is concerned. Directions for future research are presented and discussed.
Dynamics of Growth, Poverty and Inequality: A Panel Analysis of Regional Data from Thailand and the Philippines

Using panel data for provinces compiled from household expenditure microdata, the present paper empirically investigates the relationships among growth, poverty and inequality in Thailand and the Philippines. The empirical model avoids the potential bias due to the fact that the entire distribution of individual-level consumption changes over time and empirical variables for growth, poverty and inequality are often compiled from the consumption distribution. The system generalized method of moments estimation results strongly suggest that inequality reduced the growth rate of per-capita consumption, and that differences in inequality explain a substantial portion of the Philippine–Thai difference in growth and poverty reduction since the late 1980s.

Does participatory water management contribute to smallholder incomes? Evidence from Minle County, Gansu Province, P.R. China

Since the early 1990s, the Chinese water sector has undergone an important institutional reform that has shifted major responsibilities in irrigation management from the government toward water users, organized in so-called Water User Associations (WUAs). Such participatory water management is not only assumed to increase water use efficiency, but also to stimulate the incomes of member households. This study aims to provide empirical evidence of the impact of participatory water management on WUA performance and farmer incomes, using data collected for the year 2007 among 317 households and 35 WUAs in Minle County, Gansu Province. We find that having democratically elected leaders has a positive effect on WUA performance, by increasing investment levels and improving canal quality. Participation in decision making, however, has a significant negative impact on canal quality and does not affect other WUA performance indicators. Two aspects of WUA performance, investment levels and financial health, are found to have a positive impact on the farm income of member households, while water use per mu has a significant negative impact on farm incomes. We find evidence that households belonging to better performing WUAs increase their farm incomes at the expense of non-farm income. The resulting net impact of participatory water management on total household income is not significant for the households in our sample.
Photosynthetic production in the central Arctic Ocean during the record sea-ice minimum in 2012

Abstract. The ice-covered central Arctic Ocean is characterized by low primary productivity due to light and nutrient limitations. The recent reduction in ice cover has the potential to substantially increase phytoplankton primary production, but little is yet known about the fate of the ice-associated primary production and of the nutrient supply with increasing warming. This study presents results from the central Arctic Ocean collected during summer 2012, when sea-ice extent reached its lowest ever recorded since the onset of satellite observations. Net primary productivity (NPP) was measured in the water column, sea ice and melt ponds by 14CO2 uptake at different irradiances. Photosynthesis vs. irradiance (PI) curves were established in laboratory experiments and used to upscale measured NPP to the deep Eurasian Basin (north of 78° N) using the irradiance-based Central Arctic Ocean Primary Productivity (CAOPP) model. In addition, new annual production has been calculated from the seasonal nutrient drawdown in the mixed layer since last winter. Results show that ice algae can contribute up to 60% to primary production in the central Arctic Ocean at the end of the productive season (August–September). The ice-covered water column has lower NPP rates than open water due to light limitation in late summer. As indicated by the nutrient ratios in the euphotic zone, nitrate was limiting primary production in the deep Eurasian Basin close to the Laptev Sea area, while silicate was the main limiting nutrient at the ice margin near the Atlantic inflow. Although sea-ice cover was substantially reduced in 2012, total annual new production in the Eurasian Basin was 17 ± 7 Tg C yr−1, which is within the range of estimates of previous years. However, when adding the contribution by sub-ice algae, the annual production for the deep Eurasian Basin (north of 78° N) could double previous estimates for that area with a surplus of 16 Tg C yr−1. Our data suggest that sub-ice algae are an important component of the productivity in the ice-covered Eurasian Basin of the central Arctic Ocean. It remains an important question whether their contribution to productivity is on the rise with thinning ice, or whether it will decline due to overall sea-ice retreat and be replaced by phytoplankton.
RETREATMENT OF ROOT CANAL FILLINGS PERFORMED WITH A CALCIUM SILICATE BASED ROOT CANAL SEALER AND GUTTA-PERCHA WITH DIFFERENT ROOT CANAL SOLVENTS

Aim: The aim of this study was to evaluate the efficiencies of different conventional solvents on the removal of root fillings performed with MTA Fillapex root canal sealer and gutta- percha. Material and Method: Forty-five maxillary central incisors human teeth were included. Sample lengths were adjusted to 16 mm and root canal preparations were performed with K3 instruments up to 30/. 04 size. MTA Fillapex® root canal sealer and gutta percha were used to obturate the canals with cold lateral condensation technique. The teeth were stored for 1 week at 37 oC in 100% relative humidity. Specimens were randomly assigned into three groups (n:15): G1: Resosolv, G2: Endosolv E and G3: Guttasolv. 35/. 04 K3 instruments were used as the final retreatment instruments. Final irrigation was performed and root canals were dried. The teeth were split along their long axis and operating microscope at 10x magnification was used to evaluate the amount of remaining root filling material. Samples were then scored. SEM and EDS analysis were used to enhance the accuracy of evaluations. Data were subjected to statistical interpretation using Kruskal-Wallis test at a 95% confidence level ( p 0.05). Intra group comparisons showed that apical, middle and coronal thirds of each group showed no significant differences among themselves ( p >0.05). Conclusion: Root fillings performed with MTA Fillapex® and gutta percha could be retreated with the solvents used in the study. Key Words: Endodontics , Retreatment, Root Canal Therapy
Unbounded expectations and the Shooting Room

Several treatments of the Shooting Room Paradox have failed to recognize the crucial role played by its involving a number of players unbounded in expectation. We indicate Reflection violations and/or Dutch Book vulnerabilities in extant ``solutions''and show that the paradox does not arise when the expected number of participants is finite; the Shooting Room thus takes its place in the growing list of puzzles that have been shown to require infinite expectation. Recognizing this fact, we conclude that prospects for a ``straight solution" are dim.
Developing client-supplier alignment in Swedish wood supply

Historically, several different approaches have been used to foster alignment in Swedish forest operations. These approaches span from complete reliance on competitive forces in service markets, to Tayloristic management of employed workers. Which was the preferred approach has varied over time. Today, outsourcing of forest operations prevail, which combined with, relative to historical levels, few supervisors and low level of research and development efforts means that competition in the market is the primary driver of change. However, poor competition in local service markets, and increasingly complex supply chains indicate that this driver may not be sufficiently strong to on its own promote the development of more effective operations. This thesis investigates the concept of ‘harvesting operations performance’, and aims to identify ways to improve the forest industry’s supply chain by developing alignment between forest companies and harvesting contractors. Study I investigated how routinely collected follow-up data from forest machines can be used to model harvester and forwarder productivity in various conditions, and concluded that analyses of such data can help managers identify the most efficient machines for various conditions. In study II, a set of attributes of the harvesting service were identified, indicating that harvesting is a more complex service than commonly is acknowledged. Customer perceptions of contractor performance in the identified attributes were quantified, indicating substantial variation in contractor performance. Study III developed and tested a process intended to help customers of harvesting services to actively foster alignment of their employed contractors’ performance with their needs. The results from study IV, which empirically investigated benefits of alignment, suggests that if the employment of such a performance management process is successful and manages to improve alignment, increased contractor profitability and stable contractor relationships are likely to follow. A transition from market mechanisms as the primary drivers of development in Swedish harvesting operations towards more active performance management, as suggested in this thesis, will likely lead to a more positive development of operations in the future than has been the case in the recent past.
Nursing faculty and student transition to a context–based learning curriculum

Background: Context-based learning (CBL) a student-centered teaching and learning approach (STL) is used at the study site to teach undergraduate nursing theory. While it is widely accepted that transition to STL can be difficult, little is known about the perception of nursing faculty and students transition to CBL. The purpose of this study was to describe nursing faculty and students’ perception about their transition to CBL. Methods: An exploratory-descriptive qualitative design was undertaken to understand and describe the perception of nursing faculty and students transition to CBL as a teaching and learning strategy for undergraduate nursing theory courses. Results: Five themes emerged from the students’ data: throwing someone into an ocean, sink or swim, turning point, just doing it, and valuing. Four themes emerged from the faculty data on transition to CBL: an adaptation, trusting the CBL process, a maturing process for students, and controversies about CBL. While the transition was uncomfortable for students and faculty, over time both understood the benefits of CBL. Conclusions: Nursing as a practice discipline will best be served using a variety of teaching and learning strategies in the undergraduate education of nursing students. Based on the findings of this study, recommendations have been made to smooth the transition for faculty members and students not previously exposed to the STL approach using CBL.
Identification and Creation of Optimum Habitat Conditions for Livestock

Abstract Optimum habitat condition is a concept typically used for wildlife rather than livestock. The definition for optimal livestock habitat will vary with management objectives. Abiotic factors, such as topography, water availability, and thermal cover, affect animal performance and uniformity of grazing. Livestock usually prefer gentle slopes and avoid traveling long horizontal and vertical distances to water. Shade and nearby water are used for thermoregulation when temperatures are high, and topographic relief and woody vegetation can be used for thermal cover during cooler temperatures. Biotic factors, such as forage quality and quantity, influence spatial grazing preferences and affect animal performance. Livestock prefer areas with higher forage quality and quantity. Uniformity of grazing may be greater in homogeneous vegetation, but animal performance may be greater in heterogeneous vegetation, especially at lower stocking rates. Livestock grazing patterns have been predicted using multiple regression and other models, but their success has typically been limited to a specific site. Managers can improve livestock habitat conditions by changing abiotic attributes of the pastures, such as developing water, building structures for thermal cover, and changing biotic attributes of the pasture through burning, fertilizing, varying stocking rates, and manipulating grazing systems. Managers can also choose animals that are more adapted to specific rangeland conditions. Practices such as strategic supplementation and herding can modify livestock behavioral patterns to use more of the available habitat. The spatial and temporal variability of rangeland requires multiple management practices to optimize use of livestock habitat.
Evaluation of the Nutritional Status of Sudanese Respondents in Riyadh City, Kingdom of Saudi Arabia

Background: This study was designed to evaluate the nutritional status of randomly selected respondents (boys and girls) living in areas around Riyadh City, Kingdom of Saudi Arabia. Methods and finding: A simple random sample of 400 respondents with age between 6 and 19 years (200 boys and 200 girls) were selected randomly from sampling frame using random numbers table. Two types of data were collected; socioeconomic and anthropometric data. Data about the socioeconomic characteristics of the respondent’s families was collected through personal interview using a questionnaire. Anthropometric measurements of the respondents were taken. Food frequency and 24-hour recall method was used to evaluate their daily food intake. The respondents average daily intake of dietary fiber and copper was significantly (P ≤ 0.01) lower than that of the DRI. For boys the average daily intake of vitamin D and E and calcium was significantly (P ≤ 0.01) lower than that of the DRI and only folate for girls. Their intake of other nutrients was significantly higher than that of the DRI (unbalanced meals). 41.5% of boys and 46% of girls were underweight and 6.5% of boys and 4.5% of girls were suffered from severe malnutrition. Apart from the family monthly income, age, father’s education and mother’s work none of the hypothesized predictors of the respondent’s nutritional status were found to be significantly correlated with the respondent’s nutritional status indicators. However, mother work negatively correlated with the girl’s nutritional status. Conclusion: The study revealed that more than 40% of the respondents were overweight due to the fact that both respondents average daily intake of carbohydrates, protein and saturated and unsaturated fat was significantly higher than that of the DRI, while the amount of some vitamins and minerals was significantly lower than that of the DRI. None of the hypothesized predictors of the respondent’s nutritional status were found to be significantly and negatively correlated with the student’s nutritional status indicators except mother work.
