This study focuses in testing the power of reciprocity and leadership as collective action incentive structures and cooperation economic benefits in explaining collective action initiation in the context of a post-communist transition economy. The paper is based on a structured survey targeting Albanian export-oriented farmers. Different from most previous studies, this paper uses both regression analysis and machine learning procedure which is better suited for analysing non-linear relationships. The empirical findings are at odds with common sense that non-cooperation is the (...) dominant strategy, because the presence of tolerant reciprocators and leadership resources provide promising incentive structures for collective action development. KEYWORDS: Albania, collective action, collective action benefits, incentive structures, leadership, power, reciprocity. (shrink)

Abstract: This paper argues that a central explanatory role for the concept of Umwelt in theoretical biology is to be found in developmental biology, in particular in the effort to understand development as a goal-directed and adaptive process that is controlled by the organism itself. I will reach this conclusion in two (interrelated) ways. The first is purely theoretical and relates to the current scenario in the philosophy of biology. Challenging neo-Darwinism requires a new understanding of the various components involved (...) in natural selection processes. An important prerequisite for the explanation is the ability to understand development in a teleological way. Here, the concept of Umwelt plays a crucial role: if organisms are responsible for generating adaptive variation in specific environments, we need a theory that explains the context-dependent nature of adaptively oriented processes. The Umwelt is thus a central element in determining the goal that an adaptive process pursues. The second path in my analysis also has a historical dimension. I will present Karl Ernst von Baer’s reflections on teleological development and his influence on von Uexküll's thinking. I will present various ideas developed by von Baer, such as the distinction between Ziel and Zweck and the use of musical metaphors, which can help to understand development teleologically and give von Uexküll’s theory a central place in this framework.

The overwhelming majority of Albania’s urban population is located in Tirana, a city with a very dynamic socio-spatial reality, resulting as an entry point for people from various origins, including multicultural rural societies, and has significant concentrations of finance and other economic activities. Urban areas demonstrate the dynamics that impact society from many angles, including those related to technology, economics, demographics, and culture, via a diverse and changed perspective. Since 1991, there has been a growing separation between classes, genders, and (...) regions, as well as between individuals and vulnerable groups, due to a lack of social protection and governmental measures for these groups and individuals, and the unrestricted power of the free market. Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions. In order to comprehend the change over time and transition patterns of Tirana from sites of production to places of consumption, the process method is modified by concentrating on the main stakeholders. The background of enhancing cities’ mobility and competitiveness demonstrates the interaction between different social groups and different living patterns in Tirana. The study also shows the socio-spatial pattern of the new city. The significant level of social fragmentation in Tirana is evident from analysis that only investigated a certain percentage of the city’s social groupings. The new master plans predicted in the city will help to overcome the issue. (shrink)

The incorporation of thermal insulation materials into building walls is a novel strategy for reducing heating and cooling energy consumption. Nowadays, the issues of energy production, consumption, and energy storage have become global problems. Furthermore, the thermal insulation of buildings increases the thermal comfort of residential premises in order to save energy. The use of several kinds of thermal insulation materials is required in the construction sector. This paper compares the thermal and moisture performance of two different types of walls. (...) The buildings taken under consideration are located in two different Tirana neighborhoods, close to each other sharing similar climate parameters. Depending on the presence of thermal insulation, two types of walls were taken into consideration. A wall in which thermal insulation is not present and a wall with a ventilated façade system, are considered. Thermal insulation in the second case is made with rock mineral cotton. In order to obtain the most accurate results, pertinent temperature and humidity, measurements were made at several spots along the walls. The comparative analysis was performed using special measuring instruments. The temperature and moisture level in the internal walls and the temperatures of the external walls, at various spots on the walls, were taken into consideration, along with the layers of the relevant walls in both cases. The aim of this paper is to experimentally study the thermal performance of walls with various types of thermal insulation, including the ventilated façade system, as well as walls without thermal insulation. The purpose of the study is also to show how the technical and architectural methods utilized during construction affect the moisture and temperature fluctuations of the perimeter walls. (shrink)

Disputes about the causal structure of natural selection have implications for teleosemantics. Etiological, mainstream teleosemantics is based on a causalist view of natural selection. The core of its solution to Brentano’s Problem lies in the solution to Kant’s Puzzle provided by the Modern Synthesis concerning populational causation. In this paper, I suggest that if we adopt an alternative, statisticalist view on natural selection, the door is open for two reflections. First, it allows for setting different challenges to etiological teleosemantics that (...) arise if a statisticalist reading of natural selection is right. Second, by providing a different solution to Kant’s Puzzle based on individual causes of evolution, statisticalism promotes a different answer to Brentano’s Problem, what I label as Agential Teleosemantics.

The field of the philosophy of biology is flourishing in its aim to evaluate and rethink the view inherited from the previous century ---the Modern Synthesis. Different research areas and theories have come to the fore in the last decades in order to account for different biological phenomena that, in the first instance, fall beyond the explanatory scope of the Modern Synthesis. This thesis is anchored and motivated by this revolt in the philosophy of biology. -/- The central target in (...) this context is the possibility of naturalizing teleology, a classical nightmare for the history of biology itself. This requires, principally, understanding the causes of teleological explanations without assuming an unfashioned backward causation of sorts. As the riddles of teleological explanations are about their temporal dimension, I analyze different temporal scales of biological processes: evolutionary, developmental, and physiological. -/- The first one is the one defended in the context of the Modern Synthesis. As expected, one of the aims of this thesis is to evaluate the adequacy of an evolutionary account of teleological explanation. The scrutiny is negative. Evolutionary explanations in the context of the Modern Synthesis lack the necessary causal roots to naturalize teleology. Concerning the physiological scale, a long tradition pushed up by Kant and the organicist movement in the 20th century allows us to better understand how teleological explanations can be naturalized in physiological process. The key notions in this temporal scale are self-organization and the recursive, looped character of physiological process. While the physiological scale may be suitably accounted by contemporaries views, such as Autonomous Systems Theory, different central teleological phenomena remain unexplained from a purely physiological perspective. In particular, different issues concerning the (adaptive) construction of organism ---such as plasticity, robustness, variation, novelty, inheritance--- deserve an ontogenetic analysis. -/- The principal aim of this thesis is to provide a theory of teleological development that falls beyond the Modern Synthesis' framework and is prompted by different insights from the history of biology. I call it Agential Teleosemantics. It rests on two central pillars. First, that developmental processes, beyond any gene-centered stance, can be understood in informational terms; i.e. developmental processes are about the interaction of developmental resources conveying biological information. The second ingredient is agentivity, namely the idea that development is regulated by an agentive system according to the adaptiveness of the phenotypic outcomes produced. The role of agency in Agential Teleosemantic is equivalent to the role of genes in the Modern Synthesis: it is responsible for explaining the order and the adaptive complexity in the living realm. -/- The second target of this thesis regards the possibility of naturalizing intentional explanations in cognitive science. The central project involved in such an aim is known as teleosemantics. Classical teleosemantics however is etiological: it explains the teleofunctions of representational systems in terms of evolutionary processes. The different disputes in the contemporary philosophy of biology provide two insights to analyze teleosemantics in cognitive science. First, the challenges against the Modern Synthesis must be extended to the evolutionary approach of etiological teleosemantics. Second, as Agential Teleosemantics suggests an alternative source for teleofunctions ---ontogeny, I offer an attempt to integrate Agential Teleosemantics into cognitive science in order to provide an alternative teleosemantic project to understand intentional explanations in cognitive science.

In this paper, I will conduct three interrelated analyses. First, I will develop an analysis of various concepts in the history of biology that used to refer to individual-level phenomena but were then reinterpreted by the Modern Synthesis in terms of populations. Second, I argue that a similar situation can be found in contemporary biological theory. While different approaches reflect on the causal role of developing organisms in evolution, proponents of the Modern Synthesis avoid any substantial change by reinterpreting and (...) explaining individual-level phenomena from a population perspective. Finally, I will approach this debate by advocating the statistical reading of natural selection, which holds that explanations by natural selection are statistical. I will argue that the above historical conceptual reinterpretations belong to a new explanatory strategy developed by the Modern Synthesis based on population thinking. The reinterpretation of concepts at the individual level is part of the explanatory framework of the Modern Synthesis and the empty role of development within this framework. Moreover, the statistical perspective adopted here allows for the integration of two explanatory models: population-statistical and individual-causal. Finally, I will argue that this pluralistic framework can help to define the explanatory scope of the different biological approaches in order to achieve a coherent integration of development into evolution without rejecting population thinking.

The foundations of biology have been a topic of debate for the past few decades. The traditional perspective of the Modern Synthesis, which portrays organisms as passive entities with limited role in evolutionary theory, is giving way to a new paradigm where organisms are recognized as active agents, actively shaping their own phenotypic traits for adaptive purposes. Within this context, this article raises the question of whether contemporary biological theory is undergoing a cognitive revolution. This inquiry can be approached in (...) two ways: from a theoretical standpoint, exploring the centrality of the cognitive sciences in current theoretical biology; and from a historical perspective, examining the resemblance between the current state of theoretical biology and the Cognitive Revolution of the mid-20th century. Both inquiries yield affirmative answers, though important nuances will be emphasized. The cognitive sciences' explanatory framework is employed to elucidate the agentic characteristics of organisms, establishing a clear parallelism between the Cognitive Revolution and the present state of theoretical biology.

Explanatory Externalism states that the only adaptive force in evolution is natural selection. Explanatory Externalism is a central thesis of the Modern Evolutionary Synthesis. The etiological theory of natural selected-effect functions also advocates Explanatory Externalism. According to this theory, natural selection is the process responsible for determining the proper natural functions of traits. However, I will point out several challenges to Explanatory Externalism that are proposed primarily by developmental biology and its various subfields. Based on these challenges, this paper will (...) argue why biological functions cannot be fully explained by the selected-effect theory, i.e., that a theory of biological functions must adopt some kind of Explanatory Internalism. At the end of this paper, I will discuss whether or not Explanatory Internalism entails a pluralistic view of biological functions, and how this discussion is related to the different explanations of fit and diversity found in evolutionary biology.

Hospitals must have adequate lighting so that medical personnel can do their duties and attend to the requirements of patients and visitors. A comfortable recuperation environment may be created with the aid of good lighting. The relationship between daylighting and artificial lighting and their role in the design process will be mentioned. Specific areas of the hospital will be under adequate lighting analysis. The areas taken into consideration are entrance and waiting areas, circulation areas, operating theatres and clean rooms, wards (...) and bedrooms, ancillary areas, restaurant and kitchen, and exterior lighting. Some of these areas are also analyzed regarding the case study of the Military Hospital (University Trauma Hospital) of Tirana Albania. The purpose of this paper is to compare different lighting standards, the EU standards, and the Albanian ones. Solutions can be provided for lighting systems, starting from luminaries and lamps, to lighting controls and lighting management systems, from the early stage of design. The architect is the enabling partner to develop meaningful lighting solutions for all areas of healthcare facilities. (shrink)

Cities and towns are expanding and thriving as a result of urbanization, which also significantly changes the local climate. One of the most significant phenomena associated with urbanization is the Urban Heat Island (UHI) effect. This phenomenon is increasingly being studied worldwide. The paper aims to investigate the UHI phenomenon in the metropolitan area of Tirana, Albania. It analyses the impact of the UHI on four specific locations in Tirana, its causes and mitigation measures, as well as variations in surface (...) temperature, CO2 emissions, and relative humidity. The regions are measured and observed using a specific instrument such as the Testo 435. Considering the mean surface temperature variations between urban and rural regions ranging from 28.4°C to 33.7 °C, CO2 emissions from 302.9 ppm to 416.2 ppm, and relative humidity from 34.1% to 41.2%, it is found that the UHI impact in Tirana is significant. The lack of green spaces, high building density, urban patterns, building materials used, transport, and energy use are the main contributors to the UHI in central Tirana. Increasing green spaces, using reflective materials, and promoting sustainable urban design are some of the mitigation techniques suggested to reduce the UHI effect in Tirana. (shrink)

This paper is going to deal with water absorption in different types of wood such as: pine, oak, beech, and fir. The amount of water absorbed by these types of wood is known as water absorption and it is determined using the material's initial state and after their immersion in water. The major goal of this study is to explain the effects of water absorption in hardwood materials and to demonstrate the changes that will take place in them over the (...) course of 48 hours. Water can be absorbed by wood in a variety of ways, as a liquid, or as an atmospheric vapor. Despite the fact that wood can absorb other liquids and gases, water is the most important. Because of its hygroscopicity, wood, whether as part of a living tree or as a material, always contains moisture. The experiment will be focused on the selection of different types of wood (most popular in the Albanian context), analyzing their water absorption and moisture level. The wooden samples will be submerged in water for 24 and 48 hours in order to obtain the appropriate results. Their moisture level and water level due to capillarity will be analyzed too. The purpose of the study is to follow the behavior of wooden frames in different environments. (shrink)

Structuralism can be defined as an important concept of using “units” as elements of form and space-giving, where the whole form is made not only up of a “texture”, a certain flexible grid, or an algorithm of shape-giving, but it depends also on the relationships created and how people use it. The hypothesis of this study is that “Modular Construction” can also have an aesthetically pleasing outlook and that modular housing can definitely have increasing importance in the future. Modular housing (...) due to its cheap, and manufactural way of construction can be replicable in various locations. Structuralism and Modular Construction have been at the core of the Modernist movement. Although postmodernism marked the decline of modular construction adopting methods known for a more close sense of place, vernacular, and locality, which differs from the ubiquitous model of modernism, it is the universality of space and habitation seen since the times of Hippodamus Grid, Japanese Tattami systems, and rational universal space in housing known in Europe that make grid and modular design an excellent system in obtaining, rationality, functionality, flexibility, and energy efficiency, including quick construction and possibility for replication. In this regard, modular construction has a future, especially in times of crisis and economic instability. (shrink)

The use of modular construction technology has emerged as a promising solution to the challenges of the construction industry all over the world. This paper examines the new horizons and opportunities that modular construction technology offers not only in the Albanian context but also in some European countries. The paper provides an overview of the status of Albania's construction market and emphasizes the advantages of modular construction technology, including quicker construction, lower costs, and better quality control. Unfortunately, prefabricated constructions are (...) not very present Albanian construction industry, and it is not given the proper attention due to lack of infrastructure, organizational purposes, and lack of proper experience. The paper also examines the challenges associated with the implementation of modular construction technology in Albania, exploring the history of prefabricated constructions, also including regulatory barriers, lack of awareness, and the need for skilled labor. Finally, the paper concludes by suggesting strategies to overcome these challenges and promote the adoption of modular construction technology in Albania, such as targeted government policies, education and training programs, and partnerships between industry stakeholders.

The foundation of a building connects the main body superstructure to the ground. Every form of foundation and footing have a unique application in a given location for a certain weather condition. Understanding the foundation work is crucial for carrying out building activities. Due to the variety of structures they support, foundations are frequently built in different subsoil conditions and are exposed to static loads. The proper evaluation of soil-bearing capacity is fundamental to the construction of various buildings. One of (...) the quick, easy, and affordable ways to determine soil carrying capacity is the plate load test. The effect of subsoil conditions on the test results is assessed and analyzed in thorough parametric investigations. An overview of axial static and dynamic plate load testing will be given in this study. This article presents detailed processes and schematics. In an effort to highlight the differences and shared characteristics of the results, computational test results of the static load plate test and the dynamic load plate test are contrasted. A load cell, a steel plate, a hydraulic actuator mounted on a big truck to apply a load, a load cell to measure the load, and one or more linear variable displacement transformers to measure the vertical displacements make up the test setup. The maximum thrust load that should be applied to a fixed or stationary actuator when it is not moving is known as a "static load depending on the actuator's static load capacity, we can determine what a safe load is. The maximum thrust load that should be applied to the actuator while it is moving is known as a dynamic load. Dynamic load capacity refers to how much force an actuator can exert when driven and extending or retracting. With each method's benefits and drawbacks considered, it can be determined that using them in various situations and agreeing to the confrontation of these tests for the purpose of comparing results is the best course of action in order to have a base that satisfies the construction standards.

The purpose of this article is to compare several street typologies (distributed from center to suburb) in Tirana, Albania while taking into consideration pedestrian behavior on these pathways. The streets "Myslym Shyri," "Bllok," "Kombinat" (an extension of Kavaja's Street), and "Ana Komnena" (formerly "Fusha e Aviacionit") will be the primary focus of this study. The following variables will be taken into account such as pedestrian behaviors, street identity, dissatisfaction, walking distance when shifting to another zone, effects of greenery on pedestrians, (...) time spent, points of interest, frequency, pavement quality, preferred walking periods, gathering places, utilization of benches, ambulant sellers, impact of vegetation and greenery, water basins, preference for public transportation, and road signs. Direct observations and a questionnaire will be used to determine the accurate information. The study should provide recommendations as guidance for municipalities and stakeholders to better understand the behavior of pedestrians in Tirana’s context. The streets that pedestrians frequent the most include the "Bllok" area and "Myslym Shyri" Street. The pedestrian resident population on "Myslym Shyri" street, which is dominated by people of all ages, including children, youth, and the elderly, has a slight advantage over the "Bllok" neighborhood. Furthermore, there is a wide variety of urban elements on Ana Komnena Street (formerly known as "Fusha e Aviacionit"). Meanwhile, the pedestrians on Kombinati’s street suffer a little bit more because of the traffic congestion and vehicle pollution. (shrink)

Extruded polystyrene (XPS) otherwise known as a thermoplastic polymer has a closed cell structure and is often stronger, with a higher mechanical performance. XPS is a pressed material and is sold in different thicknesses ranging from 2 cm to 10 cm, thus having a weight that varies from 28 to 45 kg/m3 due to the force and pressure exerted on it. In general, XPS material has very low thermal conductivity and is resistant to bending. This material obtains typical values of (...) thermal conductivity between 0.025 and 0.040 W/m∙K., which means that it is ideal for surfaces that have to withstand weight, continuous traffic, etc. It is also resistant to moisture absorption and has a homogeneous density. Other characteristics of the material are good acoustic properties, easy assembly, and high durability over time. It should always be kept in mind that the surface where the thermal insulation will be applied must be leveled, cleaned, and dried. Primer is applied, before placing the thermal insulation on the surface. Then, XPS boards are placed on the surface, adhering to the corresponding mortar. This paper will deal with different cases of application of XPS tiles in the city of Tirana. A closer look at the resistance of this material from the day of application until today will be analyzed. The results during the observations showed high thermal stability of the material and no mold surface. EPS Expanded Polystyrene, otherwise known by the Dow Chemical trademark name STYROFOAM, is a lightweight product made from expanded plastic beads. It was first discovered by Eduard Simon in 1839 in Germany. EPS in its composition has 95% air and only about 5% plastic. This material is used because of its excellent properties, including good thermal insulation, good protective properties, and extremely lightweight. EPS is inert in nature and therefore does not result in any chemical reaction. EPS is durable, strong, and lightweight and can be used as an insulated panel system for facades, walls, roofs, and floors, as floating material in marine construction, and as a lightweight filler in road and railway construction. Different examples from the city of Tirana, of buildings where XPS and EPS materials are applied, are going to be analyzed, drawing conclusions. (shrink)

Acoustic pollution is one of the main pollutants nowadays but it is not considered of great importance in the construction field, despite some studies showing that most of acoustic pollution is produced by buildings under construction and roads with high traffic. The aim of the paper is to compare the noise levels at different time of the day in two different buildings which have different characteristics and different construction materials. The goal is to understand how well sound isolated civil buildings (...) are and how engineers have calculated the noise levels based on the specific area. The buildings are located at “Zogu Zi”, Tirana, Albania. The case study area is an area that consistently harvests noise from heavy traffic. The impact of the noise and the sound insulation materials in the wellbeing of the inhabitance is going to be analyzed too. The aim of this paper is displaying a comparative study on the actual noise levels generated by this area. It indicates the acoustic properties of the current building materials followed by a more suitable soundproof insulation. (shrink)

The aim of this paper is to make a comparison between different streets typology (with a distribution from center to suburb) specified in Tirana, taking into account the pedestrians' behavior on these streets. This paper will primarily focus on the following streets: “Myslym Shyri” street, “Bllok” area, “Kombinat” area, (an extension of Kavaja’s Street), and also “Ana Komnena” street (former “Fusha e Aviacionit”). The pedestrian actions, likeness, dissatisfaction, walking distance while transferring to another zone, greenery effects on pedestrians, time spent, (...) points of interest, level of frequency, pavement quality, the favorite time for walking, meeting points, benches usage, ambulant sellers, vegetation and greenery impact, water basins, public transport preference, and road signs are some of the topics to be addressed in this paper. Determination of these data will be made by employing a questionnaire and direct observation. The study should provide recommendations as guidance for municipalities and stakeholders to better understand the behavior of pedestrians in Tirana. The “Bllok” area and “Myslym Shyri” Street are the most frequented streets by pedestrians. “Myslym Shyri” street has a slight edge over the “Bllok” area and is populated by different categories of pedestrians involving children, youth, middle ages, and the elderly. Ana Komnena Street (former "Fusha e Aviacionit") is not lacking any urban components. Meanwhile, the pedestrians on Kombinati’s street suffer a little bit more because of the traffic jam and vehicle pollution. (shrink)

The city of Kruja dates back to its existence in the 5th and 6th centuries. In the inner city are preserved great historical, cultural, and architectural values that are inherited from generation to generation. In the city interact and coexist three different typologies of dwellings: historic buildings that belong to the XIII, XIV, XV, XIII, XIX centuries (built using the foundations of previous buildings); socialist buildings dating back to the Second World War until 1990; and modern buildings which were built (...) from 1990 onwards. According to the questionnaires, the creation of mathematical models applied to each category will result in contradictory attitudes but also fairy ones based on different percentages. There are underlined 5 quality of life indicators(questions) from a total of 30 questions of the questionnaire, which are involved in mathematical regression and are statistically significant with a significance level p<5% (with a reliability of 95%), which interact for all three categories of buildings. The quality of life indicators: dwelling area, heating mode during winter, level of dwelling improvement, time spent in the dwelling, and monthly electricity payments, are the main actors who will be compared in order to draw conclusions. According to the statistical calculations trend, it is noted that the socialist buildings category does not directly participate in the debate between historic and modern buildings by means of the quality of life indicators (questions).

Is it about energy?! This paper consists of the analysis of the construction of the Fierza's dam, built on the Drin river bed in 1978. During the study of the dam construction scheme and later during the design of the projects, various problems were taken into account, such as the geological conditions of the area where the hydropower plants were erected, the construction materials, the most suitable solution for the type of dam, the auxiliary works, their construction, sequence and time. (...) For centuries, the world's water resources have been developed to benefit mankind. The construction of dams in order to create reservoirs has served many purposes. These are some common uses such as water supply, hydroelectric power, flood control, irrigation, and navigation. The dams are also used to regulate the flow of water in rivers. Water can be released from the reservoir during drier seasons to support wildlife and the environment downstream, and to provide a resource for human uses. Dams have long been viewed as a symbol of human ingenuity and among them is the Fierza's dam, one of the greatest achievements in Albania. During the period of the construction of the dam, Albania was in difficulty to finance the design and the implementation of such works that envisaged large dams. Regardless of everything, the small state of Albania managed to build magnificent hydropower works with great economic value and a high technical and scientific level, such as Fierza's hydropower plant. This paper aims to show the importance of the construction of Fierza's dam in the production of energy in the country with an annual average output of 1,330 GWh. Also, the importance of Fierza, besides energy production, relates to the capacity of its lake, which regulates the annual inflows, increasing the efficient use throughout the cascade. (shrink)

Many countries in Eastern Europe, during the 1960–1970s, as well as Albania responded to the growing demand for new houses utilizing the emerging trends for industrialization of the construction process and mass construction of prefabricated residential buildings based on large-panel prefabricated RC elements. During the 1970s large-panel buildings spread throughout the country and became the main type of construction in the Albanian cities such as Shkodër, Tirana, Durrës, Elbasan, Berat, etc. Most of these buildings have five or six stories and (...) comprise different modules, the number of which depends on the urban and architectonic projects. The construction technology of these types of buildings included only the construction of prefabricated reinforced concrete material and did not take into account the energy performance of these structures. Since the moment of construction, only in the last year, several interventions have been made in different cities where a layer of polystyrene has been placed on the external walls of these buildings in order to enhance their thermal insulation. The aim of this paper is to improve the thermal performance of these buildings by introducing a comparison of their initial situation as they are today and how their performance would be if innovative technologies and materials were applied. The study is going to analyse the thermal performance of the existing buildings, by means of the thermal camera in the city of Kamez, located in Tirana, which has been chosen as a key study. Furthermore, the data obtained from the MEEC application are gathered, in order to compare the previous, the existing situation and the proposed intervention. The results may be used by municipalities of different cities, not only in the Albanian context, either where interventions have been made to improve their performance, or for municipalities where thermal regulation policies have not been yet implemented for these types of buildings. The existing situation of the buildings according to the calculations, showed a poor thermal performance, regardless of the fact that they are already equipped with thermal insulation building envelope. They have to be requalified in order to be categorized as a building with high thermal performance. (shrink)

This article presents information about facades, their thermal insulating role in buildings in Albania. The façade in construction is one of the necessary factors to ensure a longer life of the buildings and indoor thermal comfort. Façade systems are composed of different materials, which provide a protective effect during the life of the building. The article will focus on the characteristic materials used in Albania for the construction of facades and the main materials used from the year 2000 up to (...) today. The article will be informative, statistical, and comparative in order to draw conclusions. Nowadays building facades are again becoming one of the main subjects of discussion, undoubtedly due to the increasing importance of the building envelope in relation to energy consumption. In the 90s, minimal attention was paid to the efficiency and quality of facades; everything was done strictly in relation to residency requirements. But, during this last decade, Albania experienced a construction boom, with a series of good new buildings, which are accompanied by progress in the architectural style and in the techniques of building materials usage. However, the advantages of façade systems in construction are not only to make the building long-lasting. The function of facades always undergoes changes and advances over time, in terms of their impact on the temperature fluctuations inside the building or energy storage. (shrink)

This paper will provide information about the concrete brand produced in the factory for the prefabricated elements and the comparison of the results given by the test of resistance to compression and the results of the test of the hammer impact of the sclerometer. The idea and the need to conduct this study arose for 2 main reasons: first, from the poor results often obtained from sclerometer impact to the elements in the field, despite the compression resistance test with cubic (...) samples taken in the concrete cast and the carrot test directly on the element assembled in the building provides good results. Secondly, to have a connection between the values of the concrete brand resulting from the pressure resistance test with a press performed in the laboratory and the impact test with the sclerometer hammer which is often performed in the field under different conditions. The sclerometer impact tests will be performed on each cube sample before it is broken, in the press, and the sclerometer impact tests will be performed on the concrete elements from which the cube sample was taken on the day that this sample will be destroyed. The predicted results are relatively close values related to the age between14th day and the 28th day of the concrete maturity, as determined by the manual of the sclerometer that the study is going to use, and other values for the other days (1, 3,7,14,28). But in fact, just like in the field tests done before, it is noticed that the results obtained from the blows with the sclerometer hammer are weak. The aim of the paper is to find a logical connection between the results of these 2 types of tests. This study will contain information on the composition of the concrete produced in the IXHEM SHPK factory (ltd) located in Durres-Albania, the brands of concrete on different days for different elements, and the comparison of the results between the 2 methods mentioned above.

Albania is part of the emerging economies of the Western Balkan region. Polis University is one of the pioneering institutions in the field of architecture, built environment, and city sciences that represents innovative methodologies and concepts for educational and scientific purposes. Nowadays, many constructions in Albania involve a wide range of different materials. The building envelope is one of the main elements that provide protection from the outside environment but also the required thermal comfort for the inhabitants. The necessary balance (...) must be archived between energy efficiency and the durability of buildings. This paper will focus on the thermal performance and materials composition of two different types of masonry walls, a constituent part of Polis University's main building. The study will be based on an experiment using specific instruments to diagnose these typologies of wall composition. The results are further analyzed and compared. Specific instruments such as the thermal camera (Testo 882), U-value(Testo 435-2), and “Silverline Digital Moisture Meter” (from POLIS Energy lab) are engaged. The collected data are further interpreted through graphs, tables, and diagrams for both cases. It is observed that ventilated facades perform much better than standard facades, therefore their usage is strongly recommended. (shrink)

Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions. In order to comprehend the change over time and transition patterns of Tirana from sites of production to places of consumption, the process method is modified by concentrating on the main stakeholders. The background of enhancing cities’ mobility and competitiveness demonstrates the interaction between different social groups and different living patterns in Tirana. The study also shows the socio-spatial pattern of the new city. The significant level of social fragmentation in Tirana is evident from analysis that only investigated a certain percentage of the city’s social groupings. The new master plans predicted in the city will help to overcome the issue. (shrink)

This paper presents information about the moisture content and temperature level of brick walls in Tirana, Albania. The buildings whose walls have been studied were built in two different eras, throughout the twentieth century, and in more recent times. Given that during the second half of the twentieth century, Albania has been isolated from most of Europe and the West, and consequently the new architectural ideologies of the time, have not had the proper implementation there, the paper focuses on the (...) characteristic types of bricks used in Albania, the functions for which they are used, and their effectiveness in achieving comfort (thermal, moisture content control) during the two time periods mentioned above. Depending on the functions bricks perform in the walls studied in this paper, the walls are separated into two main groups: Walls in which bricks have structural role (red silicate brick walls, white silicate brick walls) and walls in which bricks do not have structural role (concrete block walls, holed brick walls). For all the types of bricks mentioned above, indoor moisture content and temperature measurements have been performed in all four cardinal directions. For the walls in which the bricks have a structural function, moisture measurements have been performed in all the facades of the buildings, because moisture in the bricks of these types of buildings, being a very important factor, directly affects the structural performance of the elements. The aim of the paper is to show the differences in moisture and temperature levels of the walls of these buildings, depending on the engineering and architectural techniques used during the building process, the use of insulation, and the masonry composition.

Metaphor plays a central role in changing the architectural process. In order to better appreciate the nature of architectural creativity, generating more positive forms and volumes is required. Exists many conclusions which demonstrate that metaphors plays an important role shaping the design creativity. The aim of this paper is about understanding the exact role of the metaphor in architecture design from the concept of Aristotle to nowadays. Essentially it is the process by which most of the ideas come into being. (...) Metaphors structure our understanding and perceptions. They make our thoughts more interesting and more vivid. There are similar distinct uses of metaphor in architectural criticism, which is often heavily reliant on metaphor both as a form of expression and a tool of analysis. There is a dimension of meanings attached to the various uses of metaphor, ranging from the ornamental view at one hand to the rational view at the other [1].Metaphors role in the ecological design is essential and necessary. Architects use a variety of methods and techniques to enrich the architectural language. This process is accomplished with the infiltration of metaphors as a literary figure. By adopting the models of nature, there is a chance to work more sustainably and produce more sustainable products. Is this the paradigm shift we have been looking for? Maybe biomimicry and nature could be super metaphors in order to develop sustainable design. This paper should take in consideration also the metaphor as a tool implemented into design reflecting either positive or negative reactions. This theory should be explained by concrete examples. The working metaphor in the design process is another important issue to be judged. The aim of this paper is to demonstrate that architectural metaphors corporate in coherent ways with architectonic language shaping its functionality. Metaphor helps to perceive things from a different perspective that is new to us, changing and bringing new ideas. Architectural metaphors can be found everywhere also in the Albanian case. It is very evident how metaphor stretches architectural functionality. (shrink)

This paper determines the acoustic properties of external wall building materials composition. Noise pollution is one of the main pollutants nowadays but it is not considered of great importance in the construction field, despite some studies showing that greater acoustic pollution is produced by buildings under construction. The study consists of analysing two different types of buildings equipped with a different type of external masonry composition in terms of building materials. The buildings are located at “21 Dhjetori” street, Tirana, Albania. (...) Furthermore, the case study area is treated as an area that consistently harvests noise. The impact of noise pollution on the existing building materials is going to be analyzed. Those milestones will provide information regarding the noise levels, a comparison of the actual level of noise production (outdoor and indoor areas), sound transmission, and sound diminution, as well as the implementation of acoustic materials in order to improve the quality of life of the inhabitants. The selected area has the highest norms of acoustic pollution in the city according to the studies implemented by Determination of acoustic properties of building materials is an important task gaining higher importance due to the demand for suitable construction materials, located in places with high levels of noise and places with heavy traffic, such as in urban areas. The aim of this paper is to display a comparative study of the actual noise levels generated by this area. It indicates the acoustic properties of the current building materials followed by a more suitable soundproof insulation. (shrink)

The focus of the paper is the comparison between the two composite aluminum panels, respectively Alpolic and Durabond. The paper is going to explore their reaction when interacting with Tirana`s climatological factors and their tension strength through an experiment, in order to find out which panel displays the best performance. The construction urge is constantly evolving, especially in Tirana mostly because it is the main industrial and economical district of Albania. It is distinguished that innovative technology is being used in (...) facades of the new buildings. One of the features that finds massive use in façade coating in the city is the application of ventilated facades equipped with external aluminum composite panels. This paper is going to deal with two buildings with different typologies of external coating, including the different types of aluminum panels. The analysis will focus on identifying each panel property such as tension strength; their respond to various external factors; their thermal conductivity; and their manufacturing companies which have been selected and produced. Within this paper graphics displays of the records will be included, offering concentrated information and a high level of reliability for both aluminum composite panels. (shrink)

Concrete is one of the most intelligent and widely utilized man-made materials in the construction industry. Despite this, even high-quality concrete is susceptible to porosity, which reduces its serviceability period. Furthermore, there is an increasing need to increase longevity due to environmental exposure such as soil moisture, corrosive outside elements, or structural defects forming in the surface of concrete. The use of crystalline admixtures in concrete is one of the many approaches to reducing these risks. When crystalline admixtures come into (...) contact with water, they form thin crystals that fill pores, capillaries, and micro fractures, as a result making concrete a self-sealing material. When the concrete has dried, the crystalline particles remain dormant until they come into contact with additional water, which causes them to crystallize once more. This research aims to analyze and compare the material properties of commonly used concrete and concrete where crystalline waterproofing is present. Furthermore, experiments are conducted to evaluate each of the concrete samples: compressive strength, water permeability, and flexure strength. As a result, demonstrating the benefits or negative aspects of the use of crystalline admixture in the early stages of concrete is important. It is not yet defined, whether this is the future of cutting-edge concrete and the impact that it will have in the Albanian building market. (shrink)

Gjirokastra’s buildings occupy a special place in the housing typology of Albanian popular dwellings in the feudal period. The “popular tower" is linked with its defensive character, therefore in many cases, it takes the name of a castle or defensive tower. This paper takes into consideration a typical example of the historical fortified dwelling in a well-known city of Albania, Gjirokastra. The methodology used in order to improve the way of thinking, the way of implementing, and the way of designing (...) future dwellings is very related to the historical attitude of the dwelling. Based on the historical documentation, of the fortified dwelling a real analysis is performed according to the logic of modulations. The purpose of this paper is to create a methodology for future generations of architects in order to better engage in the design process, respecting the valuable architectural history. The modern dwellings of Gjirokastra historical-urban context must adopt the historical architectural elements, the historical manners of construction, the typical construction materials, the operational mode, and people’s lifestyle, in order to preserve the city's historical values via a modern touch. KEYWORDS: Architectural elements, historical preservation values, geometric ratios, modular. (shrink)

El objetivo de este ensayo es analizar cómo confluyen en una misma base teórica tres discursos de diferentes áreas. Uno de ellos es la ciencia, mediante el genocentrismo defendido en la síntesis moderna en Biología. Otro es el de la religión, mediante la perspectiva finalista del alma y del diseño divino, que comparten las religiones abrahámicas. Y finalmente, en la esfera político-social, donde diferentes movimientos conservadores se oponen a replantear la agenda de derechos. La confluencia teórica que nuclea a las (...) tres áreas mencionadas es un preformismo sobre los organismos. Por lo tanto, primero, veremos cómo el preformismo se encuentra presente en biología. Segundo, señalaremos dos ideas relacionadas al preformismo que subyacen tanto en la biología como en la religión. Finalmente, analizaremos cómo ambos discursos, el científico y el religioso, se encuentran presentes y empleando un rol argumentativo en debates actuales sobre derechos humanos, específicamente, relacionados al aborto ya los derechos de la población lgtbiq+. La principal conclusión es que la síntesis moderna promueve erróneamente una defensa de un preformismo genético, con connotaciones religiosas, que es usado por movimientos conservadores en el ámbito político-social.

Solutions to the urban problems of the future must assume the new reality of megacities. The inevitable technological progress must find a balance with the ‘bio-ecological' recovery of the natural environment. In the vertical bionic city, all these occur; bio intelligence and giant structures of the city are merged into a single. These structures try to survive by relying on working together as a single organism alive, as ants work in their nest. What makes them so efficient? What makes them (...) work all together? What will be the future form of our building environment? Our future habitable environment is more likely to be in a vertical built form, against the horizontal city form. There are many reasons to believe that the new vertical cities will be more sustainable than the conventional horizontal cities. If this logic is accepted as the future scenario, then the question facing all planners and architects today is: Should we take this built form and make it more socially accepted, physically habitable, and human? This paper examines some of the key implications of this scenario, and the criteria for the design and planning of our future sustainable built environment as the vertical cities in the sky.

The aim of this paper is to have a better architectonic insight over the museum of Gjergj Kastriot Skanderbeg in the city of Kruja. The history for which Albanians are proud will be the focus of this paper from its genesis until now, always seeing its architectural perspective. The castle as the last resistance of Albanians at the time of Turkish occupation will be analyzed; together with the mode of implementation of the new Museum Gjergj Kastriot Skenderbeu at the time (...) of socialism. Who were the ideas of the ideologies of the time? What were the secrets of the building design? What were the secrets of the construction of the building? What were the motivations and inspirations of the architects and the design group? The paper will contain historical dating, direct interviews with architects of the building, and authentic architectural analysis of the building. Museum of Kruja is a work that belongs not only to Albanians but all of Europe and Balkan. Today it is one of the most visited works throughout the country. (shrink)

The first signs of historical settlements in Tirana date back to the year 1614. These settlements and their road system belongs to the Ottoman city structure. Nowadays this historic northeast area of Tirana consists of a conglomeration of buildings that date back to different historical periods. A good part of these dwellings are informal ones, which damage the morphology of the area. This paper is considering a genuine historical basis to create an intervention model in this specific area of Tirana. (...) The total surface of the area which is rigorously analyzed is 2.08 ha. Regulatory plans that will be considered for this analysis are the regulatory plans of 1917, 1921, 1937, 1953, 1980, up to today (the existing situation of the city of Tirana). The whole area will be analyzed including the typical road system; the typical structure of the dwellings, and the typical morphology of the area. All dwellings will be filed, according to historical dating situation and the existing situation. The current local general (PPV) plan provides a radical intervention in this area which seriously damages the historical heritage of the city of Tirana. This article aims and focuses on a territorial development model recovering it and not damaging it, (in contradiction with the current regulatory plan). The new model will be clearly detailed (up-to-level plans). The city of Tirana needs historical heritage and historical identity. How can one damage such treasure which the time took care so much to create and preserve? Such allusions are to be spoken out loudly! (shrink)

Kruja is a middle-range city located in the center of Albania. The city of Kruja dates back to its existence from the V-VI century and extends to the city around the VI and IX centuries. It becomes the first capital of Albania in the XI-th century, specifically in 1190. This paper is going to deal with only two groups of buildings that are an integral part of the historical city of Kruja, the historical dwellings (XVIII century) and the socialist ones (...) (1960-1985). This paper aims to analyze through linear regressions the relation between two parameters: moisture content and temperature of the indoor walls and floors of the historic and socialist buildings in the city of Kruja. Three types of historic dwelling and three types of socialist apartments have been analyzed, relatively uniformly oriented. The measurements with specific instruments are done on the same day, for three hours. The degree of reactivity is different for both groups of buildings. The historical buildings are more sensitive to temperature rise. They respond invers to it (as the temperature rise, the level of the moisture content decreases), with a higher coefficient than socialist ones, and appear to be more efficient in reducing the level of the moisture, despite the average moisture content being higher. This paper takes into consideration also the analysis of the materials of the construction for both categories. If the level of moisture is reduced, the buildings will be improved and the quality of life indicators of the inhabitance will be improved too. (shrink)

The aim of this paper is to analyse the people behaviour in different age buildings and different buildings typology. In the city of Kruja (Albania) exists mostly three types of buildings: the historical ones (medieval), the socialist ones (which belongs to the former communist regime) and the modern buildings. Each of them has different social and physics characteristics, different energy exchange and different building materials. The influence of all these characteristics in the exchange of energy and how they reflect in (...) changing the lifestyle of Kruja’s people is going to be analysed. A questionnaire will be undertaken to understand the way of life of Kruja’s people and to draw conclusions. A comparative analysis between all these typology of buildings will be undertaken in order to understand better the behaviour of Kruja’s people lifestyle living in these buildings. Although the conditions are not good, people tend to get a high level of place attachment and loyalty to the building they are living. The biggest energy consumers are the historical buildings and socialist ones; although the bills of the electricity are smaller than the third category they consume alternative energies and have major problems with thermal bridges. The most unfriendly categories are the socialist buildings. They prefer not to socialize much in comparison with the other two categories. (shrink)

The city of Kruja (Albania)contains three types of dwellings that date back to different periods of time: the historic ones, the socialist ones, the modern ones. This paper has to deal only with the historic building's typology. The questionnaire that is applied will be considered for the development of mathematical regression based on specific data for this category. Variation between the relevant variables of the questionnaire is fairly or inverse-linked with a certain percentage of influence. The aim of this study (...) is to have better insights into the important role of building occupancy, people's lifestyle, economic level, and the quality of life of the residents in the inner medieval citadel, the physics characteristics, and the energy efficiency of the historical dwellings. The variables such as the number of residents, quality of life, the surface of the dwellings, heating instruments and time spent in the dwelling, current living conditions, monthly bills, level of satisfaction, restoration, and building improvements, interact with each other with probabilities with different positive or negative percentages.

Socialist buildings in the city of Kruja (Albania) date back after the Second World War between the years 1945-1990. These buildings were built during the time of the socialist Albanian dictatorship and the totalitarian communist regime. A questionnaire with 30 questions was conducted and 14 people were interviewed. The interviewed residents belong to a certain area of the city of Kruja. Based on the results obtained, diagrams have been conceived and mathematical regression models have been developed which will serve as (...) a base for drawing conclusions. The purpose of this study is to find a relationship that specifies the role of the inhabitants, the role of the dwellings, the physical-mechanical characteristics, and their energy efficiency, in order to improve the living conditions of the inhabitants. The independent variables interact with each other assuming positive or negative values depending on the probabilistic mathematical regression, giving different results based on the calculated data. The variables that co-exist among them are living space, quality of life, time spent at home, social interaction of residents, dwelling humidity level, dwelling orientation, satisfaction level of the inhabitants, dwelling improvements demand, and monthly electricity bills.

In De partibus animalium A1, Aristotle presents —in a darker than usual way— decisive details of the methodology he devised for his science of nature. His indications seem to point the path along which Aristotelian biology should travel. However, numerous textual and systematic difficulties have given rise to a number of conflicting interpretations, in the context of a vigorous stream of philosophical research and debate since the last third of the last century. In this stream of studies, Michael of Ephesus’s (...) commentary on PA and his views on the subject remain relatively ignored. A complex multiplicity of factors seems to support the lack of sufficient consensus among leading contemporary specialists to explicitly consider those contributions. The purpose of this paper is to examine several of these factors and, based on the evidence provided by little explored aspects of Michael’s texts, to offer arguments in favor of that consensus against a number of alternatives. I shall argue that the contributions of this late commentator deserve to be considered —mutatis mutandis— as seriously as it is done with the main ancient Greek commentaries; in particular, in the philosophical studies of those who are currently interested in that methodology or are engaged in Aristotelian biology.
