A SIMPLE ANALYSIS OF ACREAGE RESPONSE TO SOME AGRICULTURAL PROGRAMS

The purpose of this paper is twofold: (a) To analyze the effect of some common agricultural programs on the planted area of a crop. This will be done with the framework of a simple model mostly by graphical methods. (b) To comment on an estimative procedure by which a support price, which is linked to acreage restrictions, is transformed to an "effective support price." Three programs will be analyzed, namely, unlinked support price, link support price and diversion payment.Agricultural and Food Policy, Crop Production/Industries,

COMPOUND WORDS IN ENGLISH

Language is a means of communication which is used by living beings to communicate with each other. There are many important components in language to create a successful communication, such as sound, sentence, meaning, and etc. One of the components is word. Word can be considered as a complex part in language since it has many different forms. Compound word, for example, is a word which is formed through one of the word-formation processes by combining one lexical item with another and thus produces a new word with a new meaning. This paper investigates the types of English compounds and the lexical categories which are resulted from the process of compounding. The first results showed that the types of English compounds are endocentric, exocentric, and copulative compounds. The second results showed that the lexical categories resulted from the process of compounding are noun compound, verb compound, and adjective compound. Based on the results, the researcher hopes that readers can gain deeper insight and knowledge on English compound words

TEACHERS PERCEPTIONS ON THE USE OF THE COMMUNICATIVE LANGUAGE TEACHING APPROACH IN THE ENGLISH CLASSROOMS

In teaching English, many teachers employ different approaches in order to make the teaching and learning process successfully delivered to students. One of the approaches which is oftenly used is the Communicative Language Teaching (CLT) approach. This research aims to investigate the teachers perceptions on the use of CLT in English classrooms. This qualitative study used personal interview method to collect the data. Five REAL English teachers at IONs International Education were chosen as the subjects of this research. The results showed that the teachers had positive responses towards the use of this approach. There were also several different perceptions on the weaknesses, difficulties, and criteria on applying it. The researcher hopes that this research can be beneficial to readers, particularly English teachers who wish to seek out the perceptions on the use of CLT approach in teaching students.DOI: doi.org/10.24071/ijiet.2019.03010

Speech Acts in EFL Classrooms

Speech act is a functional unit in the form of an act which helps humans understand or accomplish things with words in communication. This research was aimed to find out and analyse the types of speech acts which were performed by teachers and students in English as a Foreign Language (EFL) classrooms. The researcher employed the speech act theory from Cruse (2000) to analyse and interpret the research results. Qualitative research was applied in this research due to the data source was from the teaching and learning activities in naturalistic environments in English classrooms. The subjects of this research were teachers and students in REAL Equivalent English classrooms. The results showed that there were three types of speech acts found in the interactions between the teachers and students, namely locutionary act, illocutionary act, and perlocutionary act. Locutionary act was performed when teachers and students uttered expressions with no certain intentions. Illocutionary act, on the other hand, was performed when the expressions contained certain intentions to listeners. Perlocutionary act was performed when the listeners showed responses and acted as feedback to the speakers’ utterances. By conducting this research, the researcher hopes that it can give more insights to readers regarding to the study of speech act theory in pragmatics field.

GRAIN RESERVES AND PRICE STABILIZATION

This staff paper describes research on grain reserve stocks as a means of achieving price stability. It is assumed that price stabilization is desirable and the question of desirability is not investigated in this study. The paper is divided into two parts: Part I: Concept and Measurement of Price Instability and a Model of Price-Stocks relations Part II: A Model of Optimal Buffer Stocks for Price Stabilization -- Theory and ComputationCrop Production/Industries, Demand and Price Analysis,

Xampling in Ultrasound Imaging

Recent developments of new medical treatment techniques put challenging demands on ultrasound imaging systems in terms of both image quality and raw data size. Traditional sampling methods result in very large amounts of data, thus, increasing demands on processing hardware and limiting the exibility in the post-processing stages. In this paper, we apply Compressed Sensing (CS) techniques to analog ultrasound signals, following the recently developed Xampling framework. The result is a system with significantly reduced sampling rates which, in turn, means significantly reduced data size while maintaining the quality of the resulting images.Comment: 17 pages, 9 Figures.

Isotopic values of plants in relation to water availability in the Eastern Mediterranean region

Plant C and N isotope values often correlate with rainfall on global and regional scales. This study examines the relationship between plant isotopic values and rainfall in the Eastern Mediterranean region. The results indicate significant correlations between both C and N isotope values and rainfall in C3 plant communities. This significant relationship is maintained when plant communities are divided by plant life forms. Furthermore, a seasonal increase in C isotope values is observed during the dry season while N isotope values remain stable across the wet and dry seasons. Finally, the isotopic pattern in plants originating from desert environments differs from those from Mediterranean environments because some desert plants obtain most of their water from secondary sources, namely water channeled by local topographic features rather than direct rainfall. From these results it can be concluded that water availability is the primary factor controlling C and N isotope variability in plant communities in the Eastern Mediterranean

The status of Portulaca oleraceal in Tenerife, the Canary Islands

La recolección de material perteneciente a Portulaca oleracea y especies afines en Tenerife y algunas otras islas del archipiélago reavivó nuestro interés en este complejo poliploide. Con la intención de homogeneizar el tratamiento de los taxones relacionados a Portulaca oleracea L., se propone elevar el rango subespecífico de alguno de ellos a rango específico. Se describe por primera vez para la ciencia Portulaca canariensis. El estudio de Portulaca oleracea y especies afines en Tenerife y otras islas del archipiélago revelan los siguientes hechos: a. Tres niveles de ploidía (diploide, tetraploide y hexaploide) están presentes en las islas, b. Se observaron poblaciones simpátricas de especies diploides, de tetraploides, de tetraploides más hexaploides, de hexaploides y de diploides más tetraploides y hexaploides y c. Las especies tetraploides fueron las más frecuentes, seguidas de las diploides, siendo las hexaploides las menos frecuentes. Los resultados de los recuentos cromosómicos concuerdan con los estudios previos realizadosFollowing a comprehensive collection of Portulaca oleracea-related species in Tenerife and a few other Canary Island renewed interest this polyploidy complex led to another progress in its investigations. In order to equalize the treatment of the taxa related to Portulaca oleracea L., its subspecies are raised to the specific rank. A new species, P. canariensis is described. Our study of the Portulaca oleracea-related species found in Tenerife and a few other Canary Island reveal the following facts: a. The three ploidy levels (diploids, tetraploids, and hexaploids) are well represented there, b. Sympatric populations of diploid plus diploid, tetraploids plus tetraploids, tetraploids plus hexaploids, hexaploids plus hexaploids, and diploid plus tetraploid plus hexaploid were discovered there and c. The most frequent species found were tetraploid, then the diploid and the least were hexaploids. Chromosome count followed our findings in previous studies

Su alcune piante nuove delle Isole Pelagie

On some new plants to Pelagic islands (Straits of Sicily) \u2013 Fifteen vascular plants belonging to the families Aizoaceae, Amaryllidaceae, Asteraceae, Brassicaceae, Euphorbiaceae, Myoporaceae, Orobanchaceae, Oxalidaceae, Portulacaceae and Solanaceae are reported as new to one or both the major Pelagic islands. With the exception of Narcissus serotinus and Orobanche minor, they are non-native plants, probably of recent human introduction, mostly in areas heavily modified by man. Myoporum insulare, widely used for reforestation and for ornament, occurs also in sub and semi-natural environments
