Abstract

Using the Correct Pattern of Consumption to achieve stable and optimal patterns of consumption and use of resources, not only can increase productivity but also can increasing possibility of a successful crossing of probable future economic downturns. Productivity means using least resources most effectively to achieve growth and prosperity in all concerning aspects. The Main Objective of This Study was to investigate factors influencing the productivity of employees with regard to the mediator role of Correct Pattern of Consumption variable. The statistical population includes all government employees in Kermanshah that among them a sample of 371 individuals was selected by The Stratified approach using the Cochran formula. For Collecting Data, questionnaire was used. Based on the research literature, a model showing influence of selected variables has been tested using LISREL software. The results showed that all factors have significant and positive effects on the productivity. Considering this relationship, and taking indirect correct pattern of consumption Mediator variable into account there are significant and substantial effects. Amount of the model fit indexes (GFI=1, AGFI=0/98) demonstrate suitability of the research model.

Abstract

Considering the importance of fish consumption in provision of nutritious food for community as well as increasing per capita consumption, factors affecting the fish consumption behavior in Sari were prioritized in the present study. For this purpose, a field research was performed using a questionnaire on 266 consumers household. Beside descriptive statistical analysis by Spss19 software, inferential analysis on nonparametric statistics was done. Factors which their average score was more than 3 were identified as the main factors and using the Friedman`s test with the possibility of (<0.001) prioritizing of effective factors were determined. The results showed that quality and freshness, hygiene of Store, properties and nutritional value, trust in seller, price, species, taste, availability, the size of fish and consumption convenience were respectively among the main factors which affect consumer’s behavior in Sari. The majority of consumers (93.6 %) did not have the tendency to consume packed fish (non-canned) and instead have a great interest to use fresh fish. In conclusion, planning to increase people`s awareness in recognizing fresh fish, close monitoring of fish suppliers, decreasing of production costs and prices, easing the access by establishing standard retail markets as well as public awareness regarding the fish nutritional value can be considered as approaches for planners and activists in the field of fisheries for increasing per capita consumption and social health.

Abstract

Kangan is one of the cities in the Bushehr province in the south of Iran. Arabic language is the second language used by people after Farsi. Most of Kangan residents came from Abadan and Khoramshahr to Bushehr since the Iran and Iraq War.And, notwithstanding many years of their migration still kept the structures and words of Arabic language. This study put the emphasis on the accent of these migrants.
The purose of the study is to identify the rules and caracteristics of this arabic accent and its alterations and also identifying the syntax and semantics and intonation. This study is a descriptive and field study. Findings reveals that this accent is like other arabic varieties is come from the Arabic Language and many of its words come from Arabic. Some times we can feel the changes such as metathesis, and reducion and other changes. Too, rgarding syntax there is a visinity between the Kangan Arabic variety and Arabic Language.

Abstract

Introduction and Literature Review: Reducing energy consumption and greenhouse gas emissions to alleviate the effects of global warming have become a worldwide necessity. This matter has significant importance in Iran, because Iran has the seventh ranking position of global greenhouse gas emissions and its rate of growth is above global average. Building construction sector is experiencing a fast-paced growth in developing countries, like Iran, due to growth of economy and rapid urbanization. A large number of buildings are being built for residential, commercial and office purposes every year. Built environments are responsible for about 40 percent of energy consumption in Iran and it is generally approved that the greatest portion of built environment is dedicated to residential use. Energy consumed in producing and processing building materials and in the processes of building a house, is usually calculated using embodied energy concept. Until recently, it was generally accepted that the energy used during the occupation of a building represented a much higher proportion than its embodied energy; thus, great efforts were put into reducing energy use in this phase. New and improved technologies have reduced the operational energy through a variety of solutions, including energy-efficient equipment and appliances, improved insulation levels, low energy lighting, heat recovery systems, the provision of solar hot water systems, photovoltaic panels for generation of electricity, and other renewable technologies. However, these measures often imply an increase in materials use and energy demand for their production, which explains the growing importance of other phases in the total life cycle. According to the global literature, embodied energy of a building accounts for one third to one fifth of the total life cycle energy consumption of a specific building. However as the global trend for the new developments moves toward the zero energy/carbon buildings, the importance of the embodied energy increases. In fact embodied energy is one of the leading parameters in assessing building’s environmental performance, because in building projects, vast amounts of building materials are needed which consume great amounts of embodied energy and thus have negative effect on environment. With this preamble, improving energy efficiency of the existing dwelling stock of urban regions will increasingly be part of achieving sustainable development in future. Although this aspect of achieving sustainable development has been the subject of many global practices in recent years and global literature is almost rich in the calculations and analysis of embodied energy and life cycle energy consumption, this matter has been neglected almost completely in Iran and those few studies conducted focusing on energy in urban planning and designing fields, are mainly concentrating on transportation sector. Thus the main goal of this study is analyzing the sustainability of urban residential sector with focusing on embodied energy consumption. Methodology: In this regard, residential sector in Shiraz Metropolitan has been divided into seven different dwelling types including central-yard houses, attached terrace houses (one story houses, two story and three story houses), apartments (which are buildings of four story and above), villas and declined houses. Gathering raw data in this study was challenging, considering the fact that house building in Iran is far from industrialized and prefabricated building is really limited. Unfortunately there is no data available on the average material consumption of different dwelling types in Iran and the only study similar to this was done focusing on building structures. Using this only available data, we built our data bank in Microsoft Office excel and then focused on computing average embodied energy via multiplying embodied energy of common building materials extracted from a report conducted in the University of Bath titled “Embodied Carbon: The Inventory of Carbon and Energy (ICE)” into average material consumption based on building structures. Another point we had to take into account was the unit of the available data; while embodied energy of materials were presented in gigajoules per square meter, average material consumptions of dwellings were presented in different units from square meters, to cubic meters, kilograms and blocks. So using density of materials we established a second data base with similar units. Normalizing this raw data through dividing average embodied energy of residential dwelling by dwelling area we calculated the capitation of embodied energy for each dwelling. Afterwards we prioritized embodied energyconsumption of dwelling types from lowest embodied energy capitation to the highest as follows: brick and wood structures with about 3 GJ/m^2 embodied energy, clay brick concrete structures, clay brick steel structures, brick concrete structures, brick and iron structures, and at last brick steel structures with about5.35 GJ/m^2 embodied energy Results: To be sure of the validity of these comparisons analysis of variances (ANOVA) and Post Hoc Tests (Least significant difference- LSD) have been applied to these data in IBM SPSS statistics 19, and the result has been positive. Then collected data were shifted from structure types to dwelling types and we found out that central-yard houses with 3.6 GJ/m^2 embodied energy per capita are the most energy efficient dwelling types. After this type in sequence lay one-story terrace houses (4.21GJ/m^2 ), apartments (4.26GJ/ m^2 ), two story terrace houses (4.67GJ/m^2 ), declined houses (4.81GJ/m^2 ), villas (4.84GJ/m^2 ), and three story terrace houses (5.21GJ/m^2 ). Discussion and Conclusion: This paper highlights the need to use location-specific data in the development of building assessment schemes and the issues related to the use of embodied energy assessment for the building sector. Absence of localized data base on building material consumption on the basis of dwelling type and lack of data on cradle to grave embodied carbon and energy of common building materials were the most important obstacles in this research. On the basis of international research, paint, bitumen, platevirgin, sheet Galvanized-virgin, steel, ceramics, primary glass, iron bars, lime, cement, and common brick are the most energy intensive materials. So on account of lack of localized data, we used international embodied energy of common building materials (cradle-to-gate) to calculate embodied energy of different dwelling types. Despite of major shortcomings in data base, noteworthy conclusions have been deducted from this work which are summarized as follows: traditional form of housing in Shiraz which is known as central yard houses in this paper with brick and wood structures (in which there is a yard in the center of the block and the residential parts are located at its periphery) are the most sustainable form of housing according to this research criteria and case study. This may owe its accomplishment to the low embodied energy of common materials used in this type of housing which we may call the most environmental friendly form of housing in Shiraz. Furthermore there is a substantial lack of data on embodied energy and carbon of materials in general, and in particular on the embodied energy and carbon of buildings to be able to do an entire evaluation of buildings in their life long period. So to do a complete research in building sector (life cycle assessment), including embodied energy, gray energy, operational energy, induced energy, Demolition/Recycling Energy, and retrofit energy are unavoidable.

Abstract

Consumer behavior is a controversial and challenging issue including people, what, why and how they buy, as well as marketing and combination of marketing and market. In contemporary, man is not considered as merely a consumer of the created-value by the producers, but has rather an undeniable role in production cycle and through this seeks to gain identity, imagination, sense, value and experience. Thus, regarding the significance of the topic and the fewer research conducted, present study examined the impact of consumption values on purchase intention. In terms of aim, this study is applied and in terms of data collection procedures it is descriptive using correlation. For collecting data, a standard questionnaire were used and the data was analyzed through statistical. Statistical population and sample size were users of two Iranian mobile operators, HamrahAval and Irancell. Sample Size was determined using indefinite population formula. Results indicated that the consumption value of services provided by the mobile operators affects customers' purchase intention. In addition, among consumption values factors, functional and conditional values have significant effects on purchase intention; however, the impact of social, emotional and epistemic values on purchase intention was not confirmed.

Abstract

In the last two decades, several approaches to the theory of word formation have emerged which are sometimes quite different in spirit. In contrast to the lexicalist approaches, the theory of Distributed Morphology claims that the complex structure of a word is created in the same way as is the complex structure of a phrase or sentence. Focusing on complex agentive adjectives, the present study argues that there is aparallel between syntactic structure of simple sentences and morphological structure of synthetic compounds in Persian. For this, first the structure of simple sentences will be briefly examined within the framework of Distributed Morphology, before returning to the derivation of compounds. Then, it will be argued that the same hierarchy of lexical and functional projections, including tense and aspect projections, can be found in the morphological structure of agentive adjectives. Finlly, based on the theoretical and empirical considerations provided in the previous sections, the traditional view on the word-formation of agentive adjectives will be totally rejected.On the basis of this analysis, pairs like “dars-xān” (educating) and “dars-xānde” (educated) are both agentive adjectives which just differ in the tense feature and the presence/absence ofAspect Projection, no matter whether the verbal stem is present or past.

Abstract

This study analyzes the structure and mechanism of derivational adverbs in standard Persian with a cognitive approach. Based on this approach historical changes and appearing new categories in a language originate in the mind and cognition of the speakers. The birth of an adverb in a language bears some cognitive mechanisms in the mind. The importance of an adverb is due to this fact that it is the sole category that can be an adverb by nature or to be an adjective with the function of adverb or it is a category-functional linguistic element. Therefore, a linguistic item can be always an adverb by nature or be derived from adjectives which are derivational adverb. In comparison to other categories of a language like noun, verb, adjective, proposition- which are basic and primary categories, an adverb can be said to be a secondary category since in most cases it is derived from adjectives by derivation. In a sentence, adverb is just a grammatical function which modifies the sentence or the verb. This research will study the cognitive process of derivational adverbs in Persian which are formed by adding the suffix “aneh” to a root.

Abstract

This paper attempts to investigate the Persian morphological system in the framework of Lexical Morphology Model (Kiparsky, 1982). The main goal of this research is to study the efficacy of the model in analyzing the Persian data. Having introduced the Lexical Morphology, some data which are counterexamples to the model at first sight, will be discussed. It will be shown that on the basis of different syntactic, semantic and cognitive criteria there is some kind of conformity between the data and the Lexical Morphology Model; although it is asserted that the efficacy of the model to analyze the English data (the language on which the model is designed) is more than its efficacy in Persian. In addition, the author suggests that in order to cope with some inadequacy that Kiparsky’s model encounters to analyze idioms (listed syntactic objects) the model should be revised by a loop connecting the syntax level to lexicon. Therefore, idioms are firstly formed in syntax, after lexicalization they will return to syntax. It seems that this loop makes the model much more efficient.

Abstract

Syntactic movement is one of the most attractive parts of the Universal Grammar which has conserved its importance from the starting models of this theory to its recent models; and there have been a lot of explanations for the operations of this syntactic process in the language structures of different languages. Despite many efforts of Persian linguists, many issues of Universal Grammar, especially in minimalist approach, are still unexplored in the Persian language.
In this paper, we will have a more detailed investigation of the syntax of Persian sentences and the complexities of this kind of movements, on the basis of Minimalism. Regarding this objective, we will introduce some unique and distinguishing properties of downward movements and will study four types of downward movements in Persian language, from which downward movements of the heads of Agreement, Tense and Negation projections can be mentioned.
It seems that, accepting the possibility of syntactic downward movements, there will be better explanations for the syntax of Persian sentences and the positions of functional nodes in the hierarchical organization of Persian sentences in their derivation.

Abstract

Adopting a theory and data-based research via introducing natural morphology theory, this article, tries to study inflectional system of Persian language on the basis of congruity –system principle which is one of the components of dependent-system theory. The authors have stated unique features of inflectional affixes. Then, on the basis of five properties of this principle (occurrence of categorical systems and categories, occurrence of base form inflection or stem inflection, separate or combined symbolization of categories, number and manner of formal distinctions in the paradigm, occurrence of marker types related to the categorical system involved, and presence or absence of inflectional classes), the congruity of inflectional affixes of the Persian language has been measured. For this purpose these affixes have been analyzed in three macro classes: noun, verb, and adjective. On the basis of this principle adjective affixes are more congruous and uniform, but noun affixes are less natural.

Abstract

According to The Richness of the Base (ROTB) in Optimality Theory, there is no limitation on the input and linguistic variation in this theory which is defined as permutation of constraints. Assuming Sorani Kurdish verbal form to be more intact than those of Ardalani and Kalhori dialects, it is treated as the proto-form and, following OT principles, and by showing different constraint permutaions, an instance of variation among these three dialects is put forth. To do so, having interviewed 10 native speakers of Sorani, Ardalani and Kalhori each, and having obtained an audio corpus, the authors consider the Sorani form as an input, putting it into different constraint tableaux, and different constrains permutation resulted which is thought to be the reason of variation. In Kalhori and then in Ardalani more markedness constrainsts are active than in Sorani. OT can deal with the variation perceived in verb forms in Kurdish dialects well.

Shopping Mall Success in Terms of Factors Affecting on Customers' Shopping Welfare



Abstract
This paper presents a model to explain the role of the welfare of shopping customers is conducted on the success of commercial complexes in the country. Based on data collection, the present study is considered as descriptive. Before collecting the data through questionnaire, and so as to check the validity and reliability of the study, a pre-test was taken. Moreover, to assess the validity of the study, the diagnostic validity (DV) using an average variance extracted (AVE) was first calculated and the composite reliability (CR) was then applied to determine the reliability. Therefore, first the researchers reviewed the research literature, then, statistical sample of the population who were the customers of five commercial complexes in Tehran, were selected and the research hypotheses were tested using structural equations and regressions. The findings indicate a significant impact of variables of Functionality, ease of shopping and entertainment on shopping welfare and significant impact of variableof shopping welfare on complex commercial success, but the impact of the variables of Security and self-congruity on shopping welfare are not approved.

Abstract

The study of the syntax of the Iranian languages has gained few attentions and Sogdian in this case is not an exception. Due to the fact that the Sogdian texts are recognized as translations of other languages, the scholars have a disinclination to pay attention to the syntax of these texts.  Determining the scale of the influence of the syntax of the source languages from one hand and the distinction between the various types of this language on the other hand needs to be proved by studying and comparing the similar constructions in different type of this language variations. This essay studies and classifies the complement verbs of two major Sogdian modal verbs: s’c- and k’m-. In the previous studies on their syntax, the use of complement has been generally considered just by infinitive. This study shows that the complement of these verbs is more diverse than what was previously thought. The use of various types of infinitive and also different moods of verbs in the subordinate sentences are the other types of their complements. The verb sʼc- has less frequency in the texts other than Buddhist ones, and the variety of its complements is less than kʼm-, but the frequency of kʼm- in Christian and Buddhist texts is relatively equal and provides the ability to compare and analyze the difference of these two language types.

Abstract

The purpose of the present research is to investigate the formation of locative nouns in Persian which are not semantically similar in spite of their resemblance in functions. The suffix "-zâr" in Persian, for instance, indicates both the concept of location and multiplicity of something: "golzâr and lâlehzâr". The other suffixes of location, however, do not bear this semantic property. It's worth mentioning that along with the above mentioned process, two other processes of "compounding" and "derivation-compounding" are also investigated here. Thus, the authors in the present research have attempted to investigate these semantic constraints which are dominant on such suffixes, using the achievements of cognitive morphology such as categorization theory, conceptualization and configuration. Eventually, the authors attempt to introduce the cognitive potentials contributing to the formation and usage of these locative forms

Abstract

This paper aims to study some Muslim economists’ views towards pre- suppositions of demand theory in economics, benefiting from the method of analyzing rational behaviors, as well as considering the epistemology of utility. In economics in general and Islamic economics in particular, there not only exists a sharp difference in utility - as a basis for demand theory, but also, there are some vital differences in recognizing utility. Considering the differences here influences theorization of demand in Islamic economics.

Abstract

The present study, using some morphological Persian constructions, explores Morphological Doubling Theory (Inkelas and Zoll 2005, henceforth MDT) and its essential claim as regards resulting reduplication when the morphology calls twice for a constituent of a given semantic description. In contrast to the previous theories and approaches categorizing reduplication as phonological duplication, MDT categorizes it generally as reduplication of given morpho- semantic features. To answer the research question and know whether the formation of Persian reduplicated constructions are explainable and justifiable in MDT framework or not, using two categories of semantic and morphotactic evidence, some Persian data are analyzed in MDT framework. Semantic evidence such as root allomorphoy, synonym constructions, echo reduplication, medial full reduplication and antonym constructions together with morphotactic evidence such as ezafe vowel, indifference-ke construction, interfix, linker or enclitic and melodic overwriting are some pieces of used evidence for exploring MDT framework in the studied constructions in Persian. The present study, with a descriptive-analytic method, has been carried out by studying some Persian data gathered through people’s daily natural conversations, written works on Persian morphology and authors’ intuition. Analyzing the gathered data reveals that adopting MDT, in addition to presenting a comprehensive description and analysis of Persian reduplication, makes it possible to describe and study the structure and semantic of the reduplicated constructions that were not appropriately analyzable previously.

Abstract

In Arabic language and literature, sometimes words with different meanings and parsing are used in a single meaning. Since the language of the Qur'an is also Arabic, it can be seen that some words in different verses signify one and the same meaning.  Knowing the synonymy  of words is very important in achieving the meaning of these words in the Qur'an, and of course this importance is very evident in the discussion of translation. In the meantime, what is necessary is to what extent the translators have been diligent in recognizing these synonymous words, in presenting their correct meanings, and of course translating correctly? Accordingly, the present study has tried to examine the four words " Khatm, Tabe, Sarf and Gholf " in a descriptive-analytical method, in conjunction with the word Ghalb, and to examine and evaluate the meaning provided by the translators in question. The findings indicate that, firstly, knowing the words with the same meaning can be of great help in providing a correct translation of these words in different verses. Secondly, in the study of the synonymy of the words " Khatm, Tabe, Sarf and Gholf " it was obtained that these words in connection with the word Ghalb express a single meaning.

Abstract

A laboratory dryer used for a thin layer of  165 g Thompson orange slices with three thickness levels of 2, 4 and 6 mm, five different temperatures of  40, 50, 60, 70 and 80 °C and three air speed levels of 0.5, 1 and 2 m/s were employed to find the best dried and minimum energy consumption. This experiment was done in a complete randomized block design with the factorial treatments performed in three replicates. The energy consumption for drying thin slices of orange was calculated accordingly. The analysis of results showed that the lowest and highest drying energy consumption were 3.35 kWh (for 2 mm slice thickness and 40 °C)  and 15.2 kWh (for 6 mm slice thickness and 70 °C), respectively.

Abstract

Internal thermal conditions and cooling load of the buildings intensely depend on outdoor conditions. Outdoor conditions of the building are not constant during a day, so assumption of constant thermal conditions for indoor is not proper. It seems that using adaptive temperature panels proportional to the variations of outdoor conditions decreases the energy consumption in comparison with constant temperature cooling panels. In this paper the effects of adaptive temperature metal panels are investigated on energy consumption of the buildings and thermal comfort conditions of the occupants. Results of hourly analysis show that, in Tehran with maximum relative humidity of 65%, in buildings with north and south orientations, we do not need cooling systems in nearly 10 hours of a day, in remains we can provide thermal comfort conditions by radiant ceiling cooling panels with natural ventilation and without any anxiety about condensation on the panels. However, in buildings with east or west orientations we do not need to air conditioning and cooling systems in only 7 hours of a day. In these buildings condensation is inevitable in some intervals of system operation during a day. In these periods, we can decrease the probability of condensation by using mechanical ventilation. Results also demonstrate that cooling energy consumption is decreased of 29 to 45% depending on the orientation of building.
