Nuclear magnetic resonance characterization of metabolite disorder in orange trees caused by citrus sudden death disease

Citrus sudden death (CSD) is a new disease of sweet orange and mandarin trees grafted on Rangpur lime and Citrus volkameriana rootstocks. It was first seen in Brazil in 1999, and has since been detected in more than four million trees. The CSD causal agent is unknown and the current hypothesis involves a virus similar to Citrus tristeza virus or a new virus named Citrus sudden death-associated virus. CSD symptoms include generalized foliar discoloration, defoliation and root death, and, in most cases, it can cause tree death. One of the unique characteristics of CSD disease is the presence of a yellow stain in the rootstock bark near the bud union. This region also undergoes profound anatomical changes. In this study, we analyse the metabolic disorder caused by CSD in the bark of sweet orange grafted on Rangpur lime by nuclear magnetic resonance (NMR) spectroscopy and imaging. The imaging results show the presence of a large amount of non-functional phloem in the rootstock bark of affected plants. The spectroscopic analysis shows a high content of triacylglyceride and sucrose, which may be related to phloem blockage close to the bud union. We also propose that, without knowing the causal CSD agent, the determination of oil content in rootstock bark by low-resolution NMR can be used as a complementary method for CSD diagnosis, screening about 300 samples per hour.

Lessons learned from stakeholders in a facilitation intervention targeting neonatal health in Quang Ninh province, Vietnam

BACKGROUND: In northern Vietnam the Neonatal health - Knowledge Into Practice (NeoKIP, Current Controlled Trials ISRCTN44599712) trial has evaluated facilitation as a knowledge translation intervention to improve neonatal survival. The results demonstrated that intervention sites, each having an assigned group including local stakeholders supported by a facilitator, lowered the neonatal mortality rate by 50% during the last intervention year compared with control sites. This process evaluation was conducted to identify and describe mechanisms of the NeoKIP intervention based on experiences of facilitators and intervention group members. METHODS: Four focus group discussions (FGDs) were conducted with all facilitators at different occasions and 12 FGDs with 6 intervention groups at 2 occasions. Fifteen FGDs were audio recorded, transcribed verbatim, translated into English, and analysed using thematic analysis. RESULTS: Four themes and 17 sub-themes emerged from the 3 FGDs with facilitators, and 5 themes and 18 sub-themes were identified from the 12 FGDs with the intervention groups mirroring the process of, and the barriers to, the intervention. Facilitators and intervention group members concurred that having groups representing various organisations was beneficial. Facilitators were considered important in assembling the groups. The facilitators functioned best if coming from the same geographical area as the groups and if they were able to come to terms with the chair of the groups. However, the facilitators' lack of health knowledge was regarded as a deficit for assisting the groups' assignments. FGD participants experienced the NeoKIP intervention to have impact on the knowledge and behaviour of both intervention group members and the general public, however, they found that the intervention was a slow and time-consuming process. Perceived facilitation barriers were lack of money, inadequate support, and the function of the intervention groups. CONCLUSIONS: This qualitative process evaluation contributes to explain the improved neonatal survival and why this occurred after a latent period in the NeoKIP project. The used knowledge translation intervention, where facilitators supported multi-stakeholder coalitions with the mandate to impact upon attitudes and behaviour in the communes, has low costs and potential for being scaled-up within existing healthcare systems.

The importance of considering the evidence in the MTP 2014 Amendment debate in India - unsubstantiated arguments should not impede improved access to safe abortion

With the objective to improve access to safe abortion services in India, the Ministry of Health and Welfare, with approval of the Law Ministry, published draft amendments of the MTP Act on October 29, 2014. Instead of the expected support, the amendments created a heated debate within professional medical associations of India. In this commentary, we review the evidence in response to the current discourse with regard to the amendments. It would be unfortunate if unsubstantiated one-sided arguments would impede the intention of improving access to safe abortion care in India.

Gendering men: implications for gender equality

This paper provides an overview of the main questions about men’s involvement in policies and practices toward gender equality and the key debates and issues that arise from them. It argues for the importance of locating this issue in the context of the limitations and potential of gender mainstreaming and an understanding of the gendered nature of the state and the social construction of men’s gender interests. It articulates the case for encouraging men’s involvement in gender equality, whilst being conscious of the dangers of involving men, and outlines a strategy to work through the dilemmas and tensions.

The Schwarmgeister: The Development of Ecclesiastical Doctrine Through Schismatic Movements

Throughout the Christian story, Church doctrine and ecclesiology have been shrouded in controversy. From the Council of Nicea in 325, when are early Church fathers debated about the Trinity of Christ all the way to the modern day with Vatican II theological controversies have been important in the molding of Christian doctrine on the structure, role, and function of the Church. What makes those controversies different from the ones I treat in my thesis is that the previously mentioned controversies did not lead to schismatic divisions in the Church. The Donatist controversy and Luther's theological battle with Karlstadt were major movements that endangered the unity of the Church. These controversies propagated crucial writings and teachings in two major areas. The first area is the spiritual power and validity of the sacraments. Second is the role, function, and ecclesiology of the Church, with particular attention to the authority of the ministry. I want to demonstrate that these controversies refined the Church's thinking on sacramental issues such as baptism and Eucharist, as well as address the question of who has the power in the Church? And to what extent do they have the power to press reforms?

Primary school music

Primary teaching and music qualifications - a rare combination, not only in New Zealand today but in primary schools the world over for more than a decade. Helen Stowasser (1993) writes of 'insecure music teachers' and questions the adequacy of teacher education courses. The Arts in the New Zealand Curriculum states: 'The arts develop the artistic and
aesthetic dimensions of human experience. They contribute to our intellectual ability and to our social, cultural and spiritual understandings. They are an essential element of daily living and of lifelong learning' [the italics are mine]. If our Ministry of Education truly believes this and wants
to ensure that the music discipline is adequately taught, then there are some issues to be addressed, such as recruitment of musically capable teachers; acceptable standards of professional expertise in music; content, length and timing of pre-service programmes; and making provision for teachers' ongoing development.

Critical analysis of action research-based inservice teacher education : four case histories

Changing the nature of institutionalised education is the central theme of the thesis. The potential for radical changes to classroom teaching and to inservice teacher education is considered through four curriculum and teaching reform projects structured by action -research. The problems explored through the thesis are at the levels of teaching, institutional and research practices. It is argued that the professional activity of teachers, administrators, consultants, teacher educators and researchers can be understood to be tightly bound and determined by rules for acceptable professional ways of acting which are often unquestioned and unexamined by educators themselves. It is further argued that institutionalised education is dominated by ways of thinking and acting that are inherently individualistic. The thesis analyses the ideological character of this 'individualistic1 structuring of educational practice, identifying belief systems that hold the lived reality of educators and students in place. The thesis endeavours to show that the bureaucratic character of institutionalised education primarily serves and maintains the interests of dominant groups. The thesis examines the possibilities for radical reform in classroom teaching, the support teachers need when embarking on curriculum and teaching change processes, and the possible outcomes of such reform. The thesis also examines the interaction between the institutional practices of schools, universities and regional offices in the Ministry of Education in Victoria, Australia on these reform processes in classrooms. Finally, the thesis examines the potential of action research as a research and educative process in the professional development of educators who are both critically aware of the ideological nature of institutionalised education and committed to collective social action. From the analyses of the four action research projects the thesis concludes that action research has the potential to transform institutionalised education when its own practice is firstly, developed as a liberating pedagogy and not as research projects structured by individualistic and paternalistic interests; secondly, is driven by a commitment to the political struggle for equity and social justice; and thirdly, is itself an expression of communitarian work. The thesis concludes that the transformative processes associated with action research under these conditions hold the promise of democratising the 'individualistic' character of institutional education.

Variables influencing the mathematics performance of first-year tertiary students : a case study

The need to understand which factors most strongly affect performance in first-year mathematics programs at Khon Kaen University (KKU), in North Eastern Thailand, provided the main focus of the study which is described. First-year mathematics students in the 1990-1991 academic year, from four KKU faculty groups (Medicine and Nursing, Agriculture, Science and Education, and Engineering) were involved in this study. Research literatures addressing variables which were likely to influence performance in early tertiary mathematical study, and variables associated with difficulties in learning mathematics at the transition from upper secondary school to tertiary studies, were reviewed. The first major aim of the study was to identify the variables which were good predictors of first-year mathematics performance at KKU. Results from stepwise multiple regression analyses indicated that the following predictor variables were statistically significant and entered the regression equations for most Faculty groups: School Mathematics Achievement, Self-Esteem, Study Habits in Mathematics, and Faculty of Study. Other predictor variables that sometimes entered regression equations (depending on the Faculty group) were Socio-Economic-Status, Mathematics Language Competence, Mathematics Confidence, Attitude Towards Mathematics, and Gender. Depending on Faculty group, the statistically significant variables accounted for between 11% and 74% of scores on fist-year KKU mathematics examinations. The predictor variables contributed much more to the variance of scores on first-semester mathematics examinations than to the variance of scores on second-semester mathematics examinations. It was also found that scores on the Direct Entry Examination Mathematics test (administered by KKU) and the School Mathematics Achievement test (developed and administered by the author) had stronger correlations with first-year KKU mathematics performance than did scores on the National Entry Examination Mathematics tests (administered by the Thai Ministry of University Affairs). Scores on the three pre-university mathematics achievement test instruments were better predictors of first-semester mathematics performance than of second-semester mathematics performance. It was found that the mean Mathematics Confidence of male students was statistically significantly higher than that of female students, but there were no statistically significant gender differences in Mathematics Misplaced Confidence. Only about 30% of the main sample ( 30% of the male and 30% of the female sample groups) had appropriate confidence in mathematics, that is, they thought their answers were correct when they were, in fact, correct, and they thought they were wrong when they were, in fact, incorrect. So far as Faculty performance differences were concerned, Engineering students had the highest Mathematics Confidence scores, followed by the Medicine and Nursing group of students and the Science and Education group students. Agriculture students had the lowest mean Mathematics Confidence score. No statistically significant differences occurred in Mathematics Misplaced Confidence between different Faculty groups. The second main aim of the study was to investigate why many first-year students experienced difficulties in coping with their mathematics units. A small group of senior secondary mathematics teachers, university mathematics lecturers, and first-year mathematics students were interviewed during the first semester of the 1990-1991 academic year. Interviews were conducted by the author according to a questionnaire format, and were aimed at identifying factors causing difficulty in the transition from senior secondary to university mathematical study. The analysis of the quantitative data together with the interview data indicated that the major sources of difficulty were associated with: (a) students' mathematical abilities; (b) curriculum content; (c) course organisation; (d) students' study habits; (e) instructional styles; and (f) assessment procedures. The results of the investigation are discussed in the light of the relevant literature and related research. The study concludes with recommendations which are addressed to mathematics teachers and education administrators in senior secondary schools in Thailand, to the Thai Ministry of Education, and to the KKU Department of Mathematics.

Teaching Zambian traditional birth attendants to monitor growth of infants : evaluation of an education program

The high infant mortality in Zambia is largely attributable to malnutrition. It is exacerbated by the inability of mothers to recognise threats to nutritional status and take corrective action. Advice in ‘Health Centres’ is often inaccessible to mothers. The Traditional Birth Attendants (TBAs) work with pregnant women in local communities, and the purpose of this study was to develop and implement an educationprogram in growth monitoring and nutrition for the TBAs and then to evaluate its effects. Twenty five TBAs from two peri-urban areas of Kitwe were enrolled in this pilot study and eighteen completed the program. The researcher developed and taught a program to the TBAs over ten days. A pretest was given before the teaching program to enable the researcher to obtain information about the knowledge and skills of the TBAs. Following the teaching program the TBAs were re-tested, with the same questionnaire. Focus groups were conducted to enable the TBA to provide information on the teaching materials and the education program. The TBAs then returned to their communities and put into practice the skills and knowledge they had learned for six months. Their practice was monitored by a trained Public Health Nurse. The researcher also surveyed 38 pregnant women about their knowledge of growth monitoring and nutrition before the TBAs went into the field to work with their local communities. The same questionnaire used with the pregnant women was administered to 38 new mothers with children aged 0 to 6 months to gain information of their knowledge and skills following the work of the TBAs. The program was evaluated by assessing the extent to which TBAs knowledge and skills were increased, the knowledge and understanding of a selection of their clients and the rates of malnutrition of infants in the area under study. The results from the research clearly indicated that the teaching program on growth monitoring and nutrition given to the selected group of TBAs had a positive effect on their knowledge and skills. It was found that the teaching developed their knowledge, practical skills, evaluative skills. That they were able to give infants’ mothers sound advice regarding their children’s nutrition was revealed by the mother’s increased knowledge and the decrease in numbers of malnourished children in the study areas at the conclusion of the research. The major outcomes from the study are: that Zambian TBAs can be taught to carry out an expanded role; field experience is a key factor in the teaching program; making advice available in local communities is important; and preliminary data on the Zambian experience were generated. Recommendations are: The pilot program should be expanded with continuing support from the Health Department. Similar educational programs should be introduced into other areas of Zambia with support from the Ministry of Health. That in administering a teaching program: Sufficient time must be allocated to practical work to allow poorly educated women to attain the basic skills needed to master the complex skills required to competently reduce faltering in their communities. The teaching materials to illustrate nutritional principles for feeding programs must be developed to suite locally available foods and conditions. Methods of teaching should suit the local area, for example, using what facilities are locally available. The timing of the teaching program should be suitable for the TBAs to attend. This may vary from area to area, for example it may be necessary to avoid times traditionally given to fetching water or working in the fields. For similar reasons, the venue for the teaching program should be suitable to the TBAs. The teachers should go into the TBAs’ community rather than causing disruption of the TBAs’ day by expecting them to go to the teacher. Data should be collected from a larger group of TBAs and clients to enable sophisticated statistical analysis to complement data from this pilot program. The TBAs should be given recognition for their work and achievement. This is something which they asked for. They do not ask for payment, rather acknowledgment through regular follow up and approbation.
