It has been widely recognised that the participation of residents is a significant issue in contemporary urban heritage conservation. However, studies confirm that the reasons behind residents' engagement are still difficult to assess, particularly in emerging countries. This paper aims to evaluate the factors that incite or prevent residents from participating in built heritage rehabilitation in the old city of Constantine, by applying the motivation-opportunity-ability (MOA) model.

A questionnaire-based survey was used to collect information from the residents. The collected data were then analysed using the structural equation model (SEM).

The findings show that the most significant factors affecting residents' participation were related to their motivations and abilities. Interestingly, factors related to the opportunities did not influence participation. Thus, autonomous rehabilitation according to the residents' motivation and abilities is more likely to be adopted.

These findings are limited to the selected sample, and some variables have been eliminated through the SEM analysis.

However, as a first attempt to study residents' participation in built heritage rehabilitation in Constantine, the paper proposes a different perspective for assessing participation by considering its means and ends simultaneously. The paper also provides guidance to local decision-makers to improve the legal framework by implementing factors that encourage residents' involvement in sustainable heritage management.

This paper aims to investigate the heritage management of the Algerian medinas subject to standardized safeguarding plans, referring only to the general community model, and then ignoring their particularities. Two medinas were selected as a case study: Annaba and Constantine.

Several methodologies of a descriptive historical issue and an exploratory study approach were used to determine the physical and cultural values of the two medinas. The objective is to see to what extent the medinas can be claimed as a place of affirmation and diffusion of urbanity.

On the basis of the results obtained, this work aims to articulate the tangible and intangible heritage as two inseparable dimensions to rethink the heritage of the Algerian medinas, taking into account the specificities and peculiarities of each of them.

This paper responds to an identified need to examine the issue of identity as a new approach that depends on the available characteristics of the historic center and the way in which planners and decision-makers use these resources as a guideline for implementing a new vision of safeguarding.

This study is addressing the widespread transformation activities made to government-built housing intended for low income urban households. These unauthorised self-help transformation activities indicate not only people's willingness to become actively involved in the housing process but also demonstrate the potential for low income families to invest to improve their living conditions. In this paper we examine the changes made to the internal layouts of multi-story walk-up flats in the recently implemented satellite town of "Ali Mendjeli" in Constantine which is one of the newly adopted solutions to ease Constantine saturated city centre, and also to respond to an acute housing shortage. These transformation activities have an effect on dwelling size, cultural norms, and internal maintenance. A survey has been conducted in selected projects and socio-economic data has been collected from a sample of dwellings. The findings of the study point to the factors, which encourage these transformations, help to understand the motives and means used by the residents in the transformation procedure, find out the characteristics of these transformations, and assess means, which can be used to plan for future transformations in proposed housing schemes. Thus, this paper tends to understand the alterations carried out by the users, and to propose recommendations in order to attenuate this phenomenon.

This article aims to clarify the link between heritage and development, focussing on how this wealth can be a resource for the promotion of tourism in the villages of the Oued Labiod valley in the Aures and reduce their backwardness.

The paper opted for a qualitative empirical study, through interviews and direct observations. The data were supplemented by literature searches. The collected data were then analysed to obtain results.

The results show that the problem of the heritage of historic villages can no longer be reduced to the contemporary phenomenon of decay and physical mutations of traditional buildings. It is a more complex issue that encompasses major concerns requiring curious, comprehensive and constitutive solutions.

Due to the particularity of the architecture and the specificity of the topography and climate of the study area, the results of the research may not be generalisable and are limited to the chosen example.

The document offers advice to local actors to ensure that heritage properties are taken into consideration in all development policies and determines that the success of these projects depends on the involvement of the local population and the improvement of the legal framework.

As the first study on the issue of sustainable tourism development of the cultural heritage of the Oued Labiod valley, the document proposes new ways of development that respect the historical values and authenticity of the heritage and involve the inhabitants.

The Ottoman cultural legacy in Algeria is made up of a diverse range of architectural structures. The Algerian government strategy in connection with the Ottoman old buildings is to restore them into museums. This study will attempt to present a contrastive analysis between two old palaces being under restoration (refurbishment), and the goal is to propose a museum route by calculating the ambiance aimed at circulating the rooms by visitors.

The authors analyzed the architectural components of the various entities by observing in situ and taking measurements for a single case study to get a sense of the results for the mid-season (spring and fall). The configuration was next evaluated by modeling the space syntax and combining it with a simulation of daylight luminance, for the period when the authors could not make measurements on-site. The ultimate goal is to combine these findings to suggest the ideal in-route for the future museum.

This research allowed the authors to propose a museum itinerary adapted to the new vocation of the palaces, which considers the daylight as an element of composition in the spaces of circulation.

The paper proposes solutions to a flow management problem encountered in several similar palaces converted into museums.

The study aims to raise questions on the museum, and to preserve such heritage from neglect by giving it a new life more adapted to the needs of the Algerian society.

The authors believe that this contribution will be a creative solution for issues related to the operation of palaces that have been converted into museums.

Massive amounts of data, manifesting in various forms, are being produced on the Web every minute and becoming the new standard. Exploring these information sources distributed in different Web segments in a unified way is becoming a core task for a variety of users’ and companies’ scenarios. However, knowledge creation and exploration from distributed Web data sources is a challenging task. Several data integration conflicts need to be resolved and the knowledge needs to be visualized in an intuitive manner. The purpose of this paper is to extend the authors’ previous integration works to address semantic knowledge exploration of enterprise data combined with heterogeneous social and linked Web data sources.

The authors synthesize information in the form of a knowledge graph to resolve interoperability conflicts at integration time. They begin by describing KGMap, a mapping model for leveraging knowledge graphs to bridge heterogeneous relational, social and linked web data sources. The mapping model relies on semantic similarity measures to connect the knowledge graph schema with the sources' metadata elements. Then, based on KGMap, this paper proposes KeyFSI, a keyword-based semantic search engine. KeyFSI provides a responsive faceted navigating Web user interface designed to facilitate the exploration and visualization of embedded data behind the knowledge graph. The authors implemented their approach for a business enterprise data exploration scenario where inputs are retrieved on the fly from a local customer relationship management database combined with the DBpedia endpoint and the Facebook Web application programming interface (API).

The authors conducted an empirical study to test the effectiveness of their approach using different similarity measures. The observed results showed better efficiency when using a semantic similarity measure. In addition, a usability evaluation was conducted to compare KeyFSI features with recent knowledge exploration systems. The obtained results demonstrate the added value and usability of the contributed approach.

Most state-of-the-art interfaces allow users to browse one Web segment at a time. The originality of this paper lies in proposing a cost-effective virtual on-demand knowledge creation approach, a method that enables organizations to explore valuable knowledge across multiple Web segments simultaneously. In addition, the responsive components implemented in KeyFSI allow the interface to adequately handle the uncertainty imposed by the nature of Web information, thereby providing a better user experience.

The purpose of this paper is to illustrate three types of basis functions and their asymptotic forms defined over the patch to model the unknown currents.

A rigorous calculation of a microstrip structure that contains isotropic and anisotropic substrates via Galerkin's method is presented. The dyadic Green's functions of the problem are efficiently determined by the (TM, TE) representation.

The resonant frequency of a rectangular microstrip patch antenna using these different asymptotic basis functions is investigated. The effect of uniaxial anisotropy in the resonant frequency is presented for these asymptotic currents.

Comparisons are made, and show that the utilization of the asymptotic basis function provides a significant improvement in the computation time over the exact form in the evaluation of the resonant frequency of a microstrip patch antenna. Convergent solutions are in good agreement with the exact sinusoid basis function without edge condition and with those obtained from literature.

Improvements to health and safety at work constantly involve organizational changes (OCs). However, the OC initiatives often fail at achieving their intended goals despite efforts to draw knowledge from various disciplines, such as sociology, psychology and information sciences, to guide the change implementation. This paper proposes a temporality approach to manage the resistance during an OC project based on the capitalization of the actors' behaviors (i.e. alignment/resistance) for successful OC implementation.

Employees in an industrial company (N = 186) undergoing an OC answered a questionnaire survey. The statistical analysis approach was used to measure the influence of the constructs of the proposed temporality capitalization approach on the OC conduct.

Results indicate that the considered constructs have positive and significant correlations with OC development. It has also been found that the employees' alignment is highly correlated with the opportunities they might gain from the OC.

The proposed temporality capitalization approach shows that providing the employees with clear objectives is not sufficient to support the change, and it is suggested that the change management has to move a step further and seek to target the perspectives of the employees to energize them around the OC and maximize their alignment.

In this paper, change management is approached through the temporality capitalization that confirms the importance of monitoring the change development through the alignment. In other terms, the curve of the adaptation of the change receivers matters and should attract more attention rather than the change implementation speed.

This paper initially presents the results of the analysis of a non linear on/off control system which is capable of generating a pulse width modulation (PWM). This technique can be used to design PWM choppers that can be dedicated to regulate fluctuating power supplies (photovoltaic, wind turbines, etc.). However, since the PWM losses mainly depend on the switching frequency, thus, the determination of an optimal frequency is required. Indeed, on the one hand, we seek to operate at high frequencies to reduce the residual noise by filtering. On the other hand, there is a limitation of the switching frequency due to the physical switching elements properties. Therefore, a compromise has to be made in order to determine an optimal switching frequency that minimizes the switching power losses. The main objective of this work is to present a technique that enables to sizing the chopper parameters based on the minimizing of the switching losses. An illustrative example of the proposed technique for sizing a PWM chopper is presented.
