It is noted that the optimal systems of radical free enterprise and radical socialism are extremes of intellectualising science. Each excludes the thought of the other. Since both theories are logically consistent, each has a compelling intellectual support base. However, both theories are flawed insofar as they make the economic reality an independent functioning entity isolated from the concepts of interdependence and broader individual and social entities. Each simplifies reality – one defines all reality in the individual while the other defines all reality in the society. The simplicity of the intellectual framework of both is the flaw which arises from using Occam′s Razor too freely in simplifying complexity. It is argued that a system that explicitly incorporates and recognises individual freedom and societal values is preferable to all other systems that are assumed to be “value free”. This could be one explanation for the emergence of the Islamic system in different corners of the world.

In 1979, twenty‐five hundred years of monarchy came to an abrupt end in Iran. Since the establishment of the Islamic Republic, the new regime has weathered internal uprisings, a costly war with Iraq, and international sanctions. It is interesting to learn the extent to which economic adversities faced by Iran have been ideologically driven. In order to assess this phenomenon, this paper utilizes a framework of analysis laid out by the scholarship of Islamic economics. In section I, the paper discusses some economic forces which underlay the 1979 tumult. Subsequently, a discussion of the new economic and social order is given. An assessment is made in the final section.

Macro models are being developed in Islamic economics literature. These models, in general, follow the program of Islamization of knowledge and combine the genuine characteristics of Islamic economics with the tools of mainstream economics. The founding leader of Millî Görüs movement in Turkey, Necmettin Erbakan, and a group of Islamic intellectuals, had developed an economic program known as the just system. This paper aims to attempt to model the just economic system (the JES) with appropriate econometric techniques.

This paper models the macroeconomics of the JES with linear equations and conducts a series of simulations to identify its outputs. Based on the closed economy assumption, this paper describes the production function with a government share, defines a charitable foundation sector, exclude the speculation motive in money demand. Savings are transferred into investments without interest. This paper also develops an econometric simultaneous-equation model of the JES.

According to the results obtained from the selected simulation scenarios, this paper concludes that the macroeconomic JES works well and produces desirable outputs as it was stated in the original program.

In future studies, the econometric estimations of the JES can be made. By adding more equations to the simple model, a medium or large scale JES macroeconomic model can be developed.

The JES can now be a source of economic policy designs.

The model can be used to address socioeconomic objectives.

It is the only Islamic economic model that has been ever developed in Turkey. The notion of the JES has not been subjected to enough economic analysis and as far as it is known, it has not yet been modeled and simulated.

This study aims to carry out numerical modeling to predict aerodynamic noise radiation from four different Savonius rotor blade profile.

Incompressible unsteady reynolds-averaged navier-stokes (URANS) approach using gamma–theta turbulence model is conducted to obtain the time accurate turbulent flow field. The Ffowcs Williams and Hawkings (FW-H) acoustic analogy formulation is used for noise predictions at optimal tip speed ratio (TSR).

The mean torque and power coefficients are compared with the experimental data and acceptable agreement is observed. The total and Mono+Dipole noise graphs are presented. A discrete tonal component at low frequencies in all graphs is attributed to the blade passing frequency at the given TSR. According to the noise prediction results, Bach type rotor has the lowest level of noise emission. The effect of TSR on the noise level from the Bach rotor is investigated. A direct relation between angular velocity and the noise emission is found.

The savonius rotor is a type of vertical axis wind turbines suited for mounting in the vicinity of residential areas. Also, wind turbines wherein operation are efficient sources of tonal and broadband noises and affect the inhabitable environment adversely. Therefore, the acoustic pollution assessment is essential for the installation of wind turbines in residential areas.

This study aims to investigate the radiated noise level of four common Savonius rotor blade profiles, namely, Bach type, Benesh type, semi-elliptic and conventional. As stated above, numbers of studies exploit the URANS method coupled with the FW-H analogy to predict the aeroacoustics behavior of wind turbines. Therefore, this approach is chosen in this research to deal with the aeroacoustics and aerodynamic calculation of the flow field around the aforementioned Savonius blade profiles. The effect of optimal TSR on the emitted noise and the contribution of thickness, loading and quadrupole sources are of interest in this study.

Herbal medicine has been used for the management of complications of diabetes. The purpose of this paper is to examine the anti-diabetic effects of Achillea millefolium extract on diabetic rats.

To this aim, 32 male Wistar rats were randomly assigned into four groups in which each group comprised eight rats. The four experimental groups were as follows: control group, diabetic control (DC) group (STZ; 50 mg/kg), diabetic rats, receiving 250 mg/kg hydro-alcoholic extract of the A. millefolium (DAM) and diabetic rats, receiving 5 mg/kg glibenclamide (DG). After 21 days of the treatment course, tissues of the kidney and blood samples were collected for histopathological, biochemical and molecular analysis.

The concentration of malondialdehyde (MDA) and glucose serum were markedly reduced in the DC group while significantly increased in DG and DAM groups (1.11 ± 0.57 to 19.4 ± 3.5 and 17.8 ± 1.2 p = 0.002 and 325 ± 0.18 to 223 ± 0.11 and 211 ± 0.32 p = 0.02, respectively). Also, the activities of glutathione peroxidase (GPx) and superoxide dismutase (SOD) were markedly reduced in the DC group while significantly increased in DAM and DG groups (9.1 ± 2.21 to 18.7 ± 3.81 and 14.9 ± 3.1 p = 0.03 and p = 0.02, respectively). The concentrations of creatinine, blood urea nitrogen (BUN) and urea were substantially decreased in DAM and DG groups as compared with the DC group (0.49 ± 0.02 to 0.27 ± 0.01 and 0.25 ± 0.01 p = 0.01, 15.6 ± 2.1 to 7.2 ± 0.68 and 8.6 ± 1.2 p = 0.02 and 114 ± 9.4 to 59.8 ± 5.2 and 64 ± 5.2 p = 0.03, respectively). Also, Bcl-2-associated X protein (BAX) expression was significantly decreased in DAM and DG groups as compared with the DC group (1.3 ± 0.32 to 0.91 ± 0.03 and 0.93 ± 0.02 p = <0.01) and Bcl-2 expression were significantly increased in DAM and DG groups as compared with the DC group (0.42 ± 0.05 to 0.88 ± 0.07 and 0.85 ± 0.06 p = 0.01).

Diabetes led to degenerative damages in the kidney of rats and increased the mRNA level of Bax, while treatment with A. millefolium could protect the kidney tissue against diabetes complications and increased the mRNA expression of Bcl-2. This study indicated that A. millefolium extracts not only improves renal function as a result of anti-oxidant activity but also modulates some biochemical factors in diabetic rats.

The purpose of this paper is to analyze HRM practices in Iran in view of underlying cultural, political and economic factors.

The paper is organized in three major parts. The first part deals with HRM concept and Iranian social context. The second part presents methodology and data analysis. The third part discusses results and illustrates HRM practices in Iranian organizations. The study involves in‐depth interviews with four Iranian managers and data collected from 82 respondents through Likert‐type questionnaires (n=82, rate of response=44 per cent).

The findings in the paper shed light on the main HRM functions in the Iranian public sector. Staffing is marked by pervasiveness of networking, entitlement, compliance with Islamic/revolutionary criteria and high job security. Compensation is described by features such as fixed pay, ascription/seniority‐based reward, and hierarchical pay structure. Training and development programs are found to be unplanned and spontaneous. Finally, the paper shows that the appraisal function receives little attention and tends to be based on subjective and behavioral criteria.

The paper shows that the study is limited in terms of HRM functions, sector and sample size. Further research may make comparison between large/state‐owned and small/private organizations.

The findings in the paper might be valuable for MNEs, NGOs, international negotiators, expatriate managers, investors and those who are concerned with this part of the world.

The paper presents a convenient approach in assessing HRM variations. The combination of qualitative and quantitative data provides a thick description of HRM enriched by secondary data and previous research. Given some commonalities between Iran and other developing countries, the findings might be of potential interest in comparative studies dealing with management transferability.

Since the election of June 2009, the Islamic Republic of Iran has witnessed a huge crisis with the outburst of street protests and demonstrations, challenging its validity. Indeed, it has been so intense that it has shaken the whole Islamic Republic for the first time since the 1979 Iranian revolution. What has happened since the disputed election was an upheaval few had anticipated, an opening of Pandora's box, with millions daring to question the, Velayate Fagih, the most important constituent of the Islamic Republic. This postelection period has created a “revolutionary”’ potential that has so far been met with repressive force and violence on the part of the ruling elites leaving no leverage for compromise. Of course, in the 30 years since the revolution, the Islamic Republic's power structures have faced factionalism. These recent developments demonstrate how deeply rooted run the contradictions and differences between the various groups. This upheaval has thrown all sorts of questions into the air: could Iran remain as a Republic? Or would Iran turn into a God's Kingdom, ever more dictatorial in its approach? Or would the splits within the ruling elites continue to crack the fabric of the regime? Will there be a similar schism to that which took place during the Constitutional Revolution in the early 20th century when a leading member of the clergy, Noori, was finally hanged in July 1909 for being openly against reform? Finally, what is the possibility of change beyond the Islamic Republic in Iran?

This paper aims to explore the level of productivity of Islamic banks specifically in selected Southeast Asian Countries from the period 2006 to 2014. Besides, this study also investigates the potential determinants of bank-specific characteristics and macroeconomic conditions that may influence the productivity of banking sector.

The present study gathers data on the 29 Islamic banks from Southeast Asian countries, namely, Brunei, Indonesia and Malaysia. The productivity level of the Islamic banks is evaluated using the data envelopment analysis-based Malmquist productivity index method. The authors then used a panel regression analysis framework based on the ordinary least square to identify potential determinants.

The domestic and foreign Islamic banks have exhibited progress in total factor productivity change solely attributed to the increase in efficiency change (EFFCH) which were mainly managerial rather than scale related. Foreign-owned banks have been slightly more productive compared to their domestic-owned bank counterparts, attributed to a higher EFFCH but insignificantly different. Furthermore, capitalisation, liquidity and world financial crisis determinants have significantly influenced productivity level of Islamic banks.

The study on the productivity of Islamic banking is still in its formative stage. To date, very limited study has been conducted to examine the productivity level in Southeast Asian, which is a strong regional hub for Islamic banking. This study intends to fill the gaps with a specific focus on the productivity level, specifically narrowing down to Southeast Asian countries in the domestic and foreign Islamic banking sector.

This paper presents a reflection on the effectiveness of using drones in the technical inspection of building facades, as a practical alternative to more expensive and heavier conventional means. In order to verify this assumption qualitatively, a number of field tests are presented and discussed.

The first stage consisted of a literature review. The analysis initially investigated drone technology. Then, an insight into some general applications in Civil Engineering was compiled, focusing in particular on the Construction Industry (CI), as well as the scope of building envelope inspections. In the second stage, field tests with drones were performed and the resulting data was appraised in order to get facade pathologies diagnosis as accurate as possible.

Through this study, the adaptability and versatility of using drones were checked. Thus, it has been confirmed that drone technology is an effective and promising alternative methodology to support technical inspection and diagnosis of building envelope pathologies. In fact, drones seem to be a worthwhile tool for supporting certain Civil Engineering activities–particularly when displaying a multirotor configuration, loading high-definition (HD) cameras, for both stills photography and video.

As the main goal of this approach was simply a qualitative assessment of evidence on the advantages of using drones compared with conventional means, other kinds of comparative analysis were not discussed in depth. However, this and other potential restrictive issues may represent an opportunity to push more developments. A deeper knowledge of data handling and clear procedures for the use of drones could be very valuable for the CI and for building envelope inspections.

In investigating this subject, this research can offer valuable input to enable a greater awareness of the use of drones in the technical inspection of buildings, particularly in hard-to-reach locations, to the detriment of conventional means. In these circumstances, this methodology can bring great benefits, particularly from an environmental impact point of view, since the resources used are much lower. In addition, a very reliable diagnosis can be achieved more quickly, and at a much lower cost.

The introduction of a standard for drone inspection practice is still at an early stage, with initial steps being taken in an apparently well-focused effort to achieve consolidation. Research studies of this kind may have an important role to play in drawing the stakeholders' attention to the benefits of using this technique, particularly for those working in the building usage phase.
