The religious attitudes of students in Adventist high schools in the Solomon Islands and Vanuatu

Hay, Anthony L., n/a January 1991 (has links)
This study investigates those factors which influence the development and formation of religious attitudes in students. While there is an increasing body of knowledge and indepth research evolving regarding this field of study there is little done in the Third World and it is the first done on students at Betikama, Kukudu and Aore Adventist High Schools. It is an "ex post facto" study and examines the effects of a number of variables-- school, age, gender, level of schooling, religion, parent's religion, religious practices, parent's schooling, country of citizenship, student future plans, number of years at school, the type of school, school life and school climate-- on the religious attitudes of students attending selected high schools. The significance of the study lies in attempting to identify those factors which assist in the development of propitious religious attitudes in students. The modus operandi of the schools in the study is to encourage students to adopt a world view and lifestyle that is consistent with the tenets and practises of Christianity as espoused by Seventh-day Adventistism. It is the purpose of this study to contribute to the identification of factors which would assist in the achieving of this objective. Those variables which were most significant in the formation of attitudes toward religion were related to the School Climate and School Life as perceived by the students. Other findings related to variables investigating Student Background, Personal Characteristics, Student Religious Practices, and Family Background. These results apparently found some variables to be significant while others appeared not to be as significant. The research seems to suggest that educators and administrators must be aware of the influence of various school experiences on the development of religious attitudes in students. If they want to succeed in their objectives, then school programmes, school curriculum, extra-curricula activities, teaching methods and teacher example should promote student worth, through such aspects as fair treatment, consistency, seeing students as individuals and nuturing caring environments. Further research may include identification of factors which seem to override the importance of gender and age on the religious attitudes of the students in the study. It may also be worthwhile to identify those facets of school life and climate which are most conducive to the development of positive attitudes toward religion.

The teaching of English as a second language in the Cook Islands : an analysis

Hermann, Upokoina Mataturua E Te Au, n/a January 1993 (has links)
The demands imposed on teachers who are L2 speakers of English, in the Teaching of English as a Second Language (TESL) have had far-reaching consequences. In these situations, the consequences are compounded when the teacher is a L3 speaker of English teaching English to students who are predominantly L2/L3 speakers. Such consequences were explicitly stated in a number of reports, reviews and observations (Elley, 1979; Chamberlain, 1987; Laws and Horsley, 1988; The Ministerial Taskforce, 1989) and others. Issues relating to quality of education and quality of English teaching were frequently addressed and questioned. The author's experience as a teacher of English, Head of the English Department at Titikaveka College and English Adviser for secondary schools led to a growing concern and need to delve into these problems at both the primary and secondary levels. In the absence of research in this important area, the author sought to conduct investigation in four schools. The author was further motivated to conduct research as a result of a number of recent changes within the education system. Major concerns were firstly, the introduction of the Grade 6 National Examination in 1991; secondly, the change-over from the South Pacific English Option paper to a full New Zealand English paper in the New Zealand School Certificate (NZSC) Examination in 1989; and finally, the introduction of the New Zealand Bursary Examination in 1992. The question foremost in the author's mind was how adequately were the schools equipped to implement such changes given an array of major constraints. In this study, it is hypothesised that, most of the problems related to TESL in the Cook Islands stem primarily, and mainly from the poor quality of teachers in the classroom. This does not deny the existence of problems which emanate from other factors which impact on TESL, such as the language policy and curriculum, the adequacy or inadequacy of teaching resources, and whether indeed they are appropriate and the kinds of teaching methods which prevail. These are all acknowledged as contributing factors. The argument presented in this study, is that, while these are contributing factors, they are considered not as important as the teacher factor. The thrust of this thesis recognises the teacher as the most important classroom resource, the "key" factor which ultimately determines the quality and indeed the success or failure of an education system. This is true in the particular context of the Cook islands where teaching-learning resources, by its broadest definition, are very limited. In terms of the quality of the teacher's resourcefulness, this in turn is determined by his/her level of education and the kind of training received. Underlying the thesis presented is the contention that if the teacher is well-educated and highly-trained, then teaching and learning for the child make the possibility of attaining Level IV, the highest stage in Beeby's paradigm more likely. That is, teaching which stresses meaning and understanding, problem solving and creativity and the catering of individual differences (Beeby 1966: 72). Needless to say, the converse is more likely to happen, where and when teachers have had very limited education, inadequate and inappropriate training. In accordance with the purpose as outlined in Chapter 1, this study comprises 6 chapters and a conclusion. Chapter 1 discusses the nature of the problem from a number of interrelated dimensions, which have to varying degrees impacted on the teaching of ESL in the Cook Islands. The chapter concludes by stressing the purpose and relevance of the study in terms of educational, economic and social significance. Chapter 2 reviews and discusses, from a historical perspective, the literature as it relates firstly to the teaching of English in the Pacific but more specifically the teaching of English in the Cook Islands. The chapter then discusses the theoretical development and research in the teaching and learning of ESL in an attempt to arrive at a theoretical framework. Chapter 3 presents the research instruments and procedures used to gather and analyse the data. In the main, office sources, classroom observations, questionnaires and interviews formed the basis for eliciting data. Chapter 4 draws together the major findings of the study. The limited size of the sample placed some restrictions on the analysis of results derived from this study. Nevertheless, the analysis identified some significant trends upon which conclusions can be drawn. The last two chapters, Chapter 5 and Chapter 6 deal with the interpretative aspects of the study with the intention of arriving at valid recommendations to the problems identified. In summary, the study found that the teacher in the Cook Islands context is the key factor in the process of teaching and learning of ESL. When the teacher is well-educated and adequately trained, then the possibility of quality teaching and meaningful learning becomes a reality for the student.

Controversy over the Pinnacle Islands Revisited

谷呈陽, Erick Gutierrez Macias Unknown Date (has links)
The persistent Pinnacle Islands controversy has been often observed from several perspectives, such as historical entitlements, territorial sovereignty prerogatives, maritime rights to exploit natural recourses, and strategic affairs. The importance of this dispute lies in the contextual necessities and interests of the governments from China, Japan, and Taiwan. Likewise, the United States implications and interests beneath the dispute have also been manifested. In this case, the Japan-U.S. strategic alliance serves as a framework for the Washington policy maintenance in East Asia. In the meantime, International Public Law as an alternative to solve the Pinnacles controversy has failed. Under those circumstances, an armed conflict among the parties is possible, yet the United States military presence can prevent them.

Linking Hydroperiod with Water Use and Nutrient Accumulation in Wetland Tree Islands

Wang, Xin 06 May 2011 (has links)
Many large terrestrial ecosystems have patterned landscapes as a result of a positive feedback system between vegetation communities and environmental factors. One example is tree island habitats in the Florida Everglades. Although they only occupy a small portion of the Everglades landscape, tree islands are important features as the focus of nutrient accumulation and wildlife biodiversity in the Everglades ecosystem. The hardwood hammock community on the elevated head of tree island habitats can accumulate high phosphorus concentration in the otherwise P-limited Everglades ecosystem. In this dissertation, I examined two hypotheses derived from the chemohydrodynamic nutrient accumulation model, which suggests that high transpiration of tree island hammock plants is the driving force for nutrient accumulation in tree island soil. According to this model, I hypothesized that tree islands with lower dry season transpiration should have less phosphorus accumulated than the tree islands with higher dry season transpiration. By examining the water use and nutrient status from 18 tree islands in both slough (perennially wet) and prairie (seasonally wet) locations, I was able to compare water availability and nutrient accumulation in slough and prairie tree islands with different marsh hydroperiods. Chapter 1 uses elemental and stable isotope analysis to look at water stress and nutrient concentration in tree island plants. I showed that the prairie tree island plants suffer from drought stress during the dry season, when the marshes in the prairies dry out. Prairie tree islands also have lower soil and plant P concentration than the slough tree islands. Moreover, I showed that foliar N isotope ratio serves as a stable proxy for community level P availability for tree island plants, and prairie tree island plants have less P available than slough tree island plants. In Chapter 2, I showed that the satellite imagery derived normalized difference water index (NDWI) provides a robust indicator of community level canopy water content of these tree islands. NDWI, used as a proxy for water status, was positively related to foliar N isotope ratio, which suggests that water availability is linked to nutrient availability in the tree island hardwood hammock plant communities. These findings are consistent to the chemohydrodynamic nutrient accumulation model. In Chapter 3, I used sap flow sensors on individual trees to provide a real-time measurement of plant transpiration. I showed that tree island plant transpiration is affected by multiple factors including weather fluctuations, marsh water depth regulated by local water management, and canopy structure of different tree islands. Overall, my dissertation establishes a link between tree island plant water use and nutrient accumulation. It could be potentially important for future restoration plan of tree islands and Everglades hydrological management.

Effects of Changes in the Everglades on Two Indicator Species: Sigmodon Hispidus and Oryzomys Palustris

Fernandes, Miguel V 21 July 2011 (has links)
The Everglades, a wetland ecosystem unique to southern Florida has been degraded by the loss of nearly half of its area to urban and agricultural development as well as by alterations to Florida’s hydrology. Modifications to the flow of water to the Everglades have altered the remaining portion of the Everglades. Most prominent among these changes in the remaining Everglades is the loss of tree islands with a disproportionately greater loss of larger tree islands. Despite their significance as “keystone habitats”, our understanding of how changes to Everglades tree islands will affect fauna is poor. In the work presented, 16 study tree islands of Rock Reef Pass, Everglades National Park, Homestead, FL, were classified into three size classes (large, medium and small) and used animal capture histories collected between February 1994 and December 2005 to investigate the relationship between tree island size classes and indirect indicators of adult female hispid cotton rat (Sigmodon hispidus) and marsh rice rat (Oryzomys palustris) fitness and reproduction. Adult female S. hispidus and O. palustris body weights were used as an indicator of adult female fitness and compared among tree island size classes. The proportions of reproductively active females, the proportions of captures of individuals in the juvenile age class and the number of juveniles per female were used as indirect indicators of female reproduction and compared among island size classes. Animal capture histories were also used to perform multi-state mark-recapture analyses, where sates were defined as three island size classes, to draw inferences about state-specific rates of survival and state transition probabilities for Oryzomys palustris and Sigmodon hispidus as a function of the most salient features of the Everglades ecosystem, namely, its tree islands and its seasonal wet and dry periods. Specifically, Akaike’s, information criterion (AIC) was used to make inferences about factors influencing survival and transition probabilities by comparing the relative fit among models where survival and transition rates are described as functions of tree island size classes and as a function of environmental variables that distinguish seasonal periods (monthly water levels, total monthly rainfall, mean air temperature, days dry, days inundated). The probabilities of individuals remaining within the same island size class were interpreted as an indirect indicator of size-class specific tree island use. Results indicated that greater proportions of S. hispidus adult females were reproductively active and had higher fitness on larger islands than females on smaller islands. The body weights of S. hispidus adult females, the proportions of individuals in the juvenile age class and the number of juveniles per female, were positively correlated with tree island area while the proportions of reproductively active S. hispidus females were not. When compared among tree island size classes, S. hispidus females recaptured on the same large island weighed more than females recaptured on the same and medium or small island suggesting that females with greater fitness are found on larger tree islands. The proportions of reproductively active S. hispidus females and of individuals in the juvenile age class were greater on larger tree islands than on smaller islands, although the number of juveniles per females did not differ among tree islands. The results also indicated that differences in the fitness and reproductive condition of O. palustris females are not as distinct among females on different size tree islands. The body weights O. palustris adult females, the proportions of juveniles and the number of juveniles per female were not correlated with island area, while the proportions of reproductively active females were negatively correlated with tree island area. The body weights of O. palustris adult females recaptured on the same large tree island were higher than those of females on smaller islands while the proportions of females that were reproductively active and the proportions of captures of juveniles were higher on small islands than on large islands. Mark-recapture analysis provided evidence that overall, Sigmodon hispidus survival rates were higher on larger islands than on smaller islands. Evidence was not found that Oryzomys palustris survival rates differed among size classes, perhaps due to the limited spatial scale of this study relative to the spatial sale of O. palustris habitat use. Both species’ survival probabilities differed between seasons with Oryzomys palustris having higher survivorship during wet seasons and Sigmodon hispidus during the dry season. Both Oryzomys palustris and Sigmodon hispidus were more likely to remain on large island than on smaller islands.

Solid waste management: the barriers to sustainability on remote islands

Chirico, Jennifer M. 14 November 2011 (has links)
Waste generation rates continue to grow around the world, creating a need for more comprehensive waste management strategies to meet sustainability needs. Remote islands are profoundly affected by the growth in waste and have a critical need to develop policy that addresses their unique characteristics, such as limited land space for waste disposal, higher per capita waste generation rates due to tourism, and lack of opportunities for interstate waste transport. This case study investigated one Hawaiian County's collaborative approach to adopting a new solid waste management policy. Ostrom's Institutional Analysis and Development Framework (IAD) was utilized to examine the facilitating and impeding institutional factors that affect the adoption of more sustainable waste management approaches on remote islands. The impeding factors that created barriers to sustainability included blueprint models, lack of financial incentives, financial cost, infrastructure, exclusion from waste services, remoteness, and illegal dumping. Facilitating factors were environmental concerns and exemplary waste examples by other communities. Recommendations are provided for addressing these barriers and using the available opportunities to work toward greater sustainable resource management on remote islands.

New methods of mass analysis with quadrupoles with added octopole fields

Moradian, Annie 05 1900 (has links)
Mass selective axial ejection of ions and mass analysis with a stability island with linear quadrupoles with added octopole fields are described. With mass selective axial ejection, quadrupoles with 2.0% and 2.6% added octopole fields have been tested and compared to a conventional quadrupole. The effects of trapping ions at different q values, excitation voltage, scan direction, balanced and unbalanced rf voltages on the rods, and dc applied between the rods have been investigated. The highest scan speeds and highest resolution are obtained with resonant excitation and ejection at high q (q = 0.8). With axial ejection, the quadrupole with a 2.0% added octopole field provides mass resolution and ejection efficiencies similar to a conventional rod set. Quadrupole, dipole and simultaneous dipole-dipole excitation between the x and y rod pairs were compared and no advantage was found with quadrupole or dipole-dipole excitation. The effects of scan speed were investigated and a resolution at half height of about 1600 is possible at scan speeds up to 5000 Th/s. Mass analysis using islands of stability was investigated with a quadrupole with2.0% added octopole field. The island of stability is formed with auxiliary excitation. The experiments confirm the predictions of the simulations. With the resolving dc applied to the quadrupole so that the Mathieu parameter a>0, conventional mass analysis with applied rf and dc and no auxiliary excitation is possible. In this case use of an island of stability yields similar peak shape and resolution. However with the polarity of the resolving dc reversed so that a<0, only very low resolution can be obtained; the added octopole prevents conventional mass analysis. By using a stability island when a<0, the resolution is substantially improved.

Undersökning av utökade användningsområden för Lotsbroverkets slam / Examination of expanded uses for the sewagesludge that is produced in Lotsbroverket

Lindfors, Elin January 2012 (has links)
Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed. In theliterature it is found that the risk of human exposure to these substances is low if thesludge is treated appropriately. Suggested appropriate treatment of the plant's sludge isthermophilic digestion whereby also pathogens are killed.The soil of the Aland Islands has a high content of phosphorus. Since 1995 there is anenvironmental program to which currently 95% of the island's farmers are connected.The program controls the use of fertilizers i.e. by setting maximum permitted levels ofphosphorus. Since sewage sludge contains relatively much phosphorus it may be alimitation of the use of sewage sludge on agricultural land of the Aland Island. That iswhy it would be suitable to use the sludge with a different fertilizer in order to obtainthe proper fertilizing properties.In Europe, the use of sewage sludge in agriculture is relatively widespread. Severalcountries have less strict laws regarding the sludge content than the Aland Islands.Because large amounts of fruits and vegetables annually are imported into the island,there is reason to believe that the population already consumes products grown onsludge treated soils. Several of the farmers on the Aland Islands are currently scepticalin terms of using sewage sludge in agriculture, mainly due to uncertainties in the sludgecontent. Regarding the certification of Lotsbroverket in accordance with the Swedishcertification system REVAQ no barriers have been found. To ensure that a certificationis possible, however, further investigations are required.

The Urban Heat Islands Analysis : Factors of Building Surface, Green Area and Lighting

Liu, Hanyue, Liu, Qian January 2012 (has links)
Summary The development of urbanization and industrialization has improved the comfort level and the quality of human’s life effectively. But at the same time, it also caused many global environment problems, such as air pollution, greenhouse effect and urban heat island (UHI).  The environment cannot keep the balance because of lots of industrial activities, anthropogenic heat and building surface effect. Almost 3 billion people, who are living in cities, have to face this situation, and the quantity is still increasing. The authors use literature research methodology, case study, comparative study and trend analysis study while writing. UHI have a harmful effect (such like photochemical smog and increasing energy use) on urban ecological environment, daily life and health. As the product of urbanization and industrialization, UHI has become one of the most important climate issues. Urban green space is helpful to reduce urban heat islands. London has a better urban green space system to face UHI and Hong Kong still has a long way to improve the green environment for reduce UHI. This article consider that roof greening is a suitable method to help Hong Kong gets rid of urban heat islands. And the lighting and population could indicate the level of urbanization, also can reflect the effect of urban heat islands preliminary. Over-capitalized lighting will exacerbate urban heat islands.

Neologismen der 90er Jahre ? Kenntnis und Einstellungen unter Deutschsprecher/innen aus Kitchener-Waterloo

Schmidt, Martin January 2006 (has links)
In 2004, the Institut für Deutsche Sprache published the neologism dictionary "Neuer Wortschatz: Neologismen der 90er Jahre im Deutschen", which contains new words that entered the German language during the 1990s (for example "Elchtest" and "Handy"). Based on this dictionary this master's thesis examines to what extent those new words have reached the vocabulary of German speakers in the German language island of Kitchener-Waterloo, Ontario. Moreover, it describes the attitudes of the local speakers of German towards these new words. <br /><br /> First, the term <em>neologism</em> is defined, different types of neologisms are presented and a review of research on German neologisms in general is given. Second, the historical background of the German speakers in Kitchener-Waterloo is described. The focal point of this thesis, however, is on the methodology of the study and on the results of the actual research coming from a data collection amongst German speakers of Kitchener-Waterloo. On the one hand, the focus of the analysis is on the question to what extent this language change in the German language in Europe has reached them. Hence knowledge and usage of the neologisms are examined. On the other hand, the focus is on the attitudes the interviewees have towards these new words. Both aspects are compared to the result of the same study administered to German speakers, who lived during the 1990s in Germany. Hence knowledge and attitudes of the Canadian German speakers can be compared to those of speakers in Germany. <br /><br /> The results show that the participants from Germany knew more neologisms than those from Kitchener Waterloo. Concerning attitudes, both groups showed a slightly positive attitude towards the neologisms with interesting differences regarding certain types of neologisms.
