Abstract

Purpose

Using critical disaster studies and state theory, we assess the disaster aid platform named Lebanon Reconstruction, Reform and Recovery Framework (3RF) that was put in place by international donors in the aftermath of the Beirut Port Blast in August 2020, in order to examine the effectiveness of its inclusive decision-making architecture, as well as its institutional building and legislative reform efforts.

Design/methodology/approach

The paper uses the case study approaach and relies on two original data sets compiled by authors, using desk reviews of academic literature and secondary data, in addition to 24 semi-structured expert interviews and participant observation for two years.

Findings

The aid platform appears innovative, participatory and effectively functioning toward recovery and reform. However, in practice, the government dismisses CSOs, undermines reforms and dodges state building, whereas the 3RF is structured in incoherent ways and operates according to conflicting logics, generating inertia and pitfalls that hinder effective participatory governance, prevent institutional building, and delay the making of projects.

Research limitations/implications

The research contributes to critical scholarship as it addresses an important research gap concerning disaster aid platforms’ institutional design and governance that are under-studied in critical disaster studies and political studies. It also highlights the need for critical disaster studies to engage with state theory and vice-versa.

Practical implications

The research contributes to evaluations of disaster recovery processes and outcomes. It highlights the limits of disaster aid platforms’ claims for participatory decision-making, institutional-building and reforms.

Originality/value

The paper amplifies critical disaster studies, through the reflexive analysis of a case-study of an aid platform.

Abstract

Purpose

This paper aims to study the after-effects of the crises hit by the Lebanese population and the solutions implemented to alleviate the ensuing problems on resource sharing in Lebanese libraries.

Design/methodology/approach

Questionnaire to academic libraries. Nine libraries in Lebanon offer resource sharing services; all nine are academic. A self-administered questionnaire was sent to these nine libraries; eight responded. A semi-quantitative approach was used to analyze the responses. The questionnaire was administered through Microsoft Forms. The form was designed to include dichotomous questions for the sake of quantitative analysis and a short answer format that allowed responders to provide additional details. American University of Beirut Data. The access services department at the American University of Beirut Jafet Library compiles on a daily basis interlibrary loan statistics. The compiled data were divided into two groups: duration of two fiscal years prior to June 2020; and from June 2020 to June 2022. June 2020 was used as a cutoff date after which the interlibrary loan initiatives in response to COVID-19 were implemented. The services that were analyzed were RSCVD, OCLC WorldShare ILL profiled groups, Emergency Temporary Access Service for HathiTrust members and Open Access Services from vendors.

Findings

Libraries in Lebanon were able to continue providing resource-sharing services with a minimal budget due to four major initiatives and through the help of the international resource-sharing community.

Originality/value

Limited publication about inter library loan in Lebanese Libraries. The pandemic hit economies worldwide; however, Lebanon got hit by three synergetic crises, and the initiatives were instrumental in drastically reducing resource sharing expenditure without affecting the interlibrary loan fill rate.

The purpose of this paper is to check the feasibility of using biomaterial such as of Phragmites-Australis (PA) in cement paste to achieve sustainable building materials.

Abstract

Purpose

The purpose of this paper is to check the feasibility of using biomaterial such as of Phragmites-Australis (PA) in cement paste to achieve sustainable building materials.

Design/methodology/approach

In this study, cement pastes were prepared by adding locally produced PA fibers in four different volumes: 0%, 0.5%, 1% and 2% for a duration of 180 days. Bottles and prisms were subjected to chemical shrinkage (CS), drying shrinkage (DS), autogenous shrinkage (AS) and expansion tests. Besides, prism specimens were tested for flexural strength and compressive strength. Furthermore, a mathematical model was proposed to determine the variation length change as function of time.

Findings

The experimental findings showed that the mechanical properties of cement paste were significantly improved by the addition of 1% PA fiber compared to other PA mixes. The effect of increasing the % of PA fibers reduces the CS, AS, DS and expansion of cement paste. For example, the addition of 2% PA fibers reduces the CS, expansion, AS and DS at 180 days by 36%, 20%, 13% and 10%, respectively compared to the control mix. The proposed nonlinear model fit to the experimental data is appropriate with R2 values above 0.92. There seems to be a strong positive linear correlation between CS and AS/DS with R2 above 0.95. However, there exists a negative linear correlation between CS and expansion.

Research limitations/implications

The PA used in this study was obtained from one specific location. This can exhibit a limitation as soil type may affect PA properties. Also, one method was used to treat the PA fibers.

Practical implications

The utilization of PA fibers in paste may well reduce the formation of cracks and limit its propagation, thus using a biomaterial such as PA in cementitious systems can be an environmentally friendly option as it will make good use of the waste generated and enhance local employment, thereby contributing toward sustainable development.

Originality/value

To the authors best knowledge, there is hardly any research on the effect of PA on the volume stability of cement paste. Therefore, the research outputs are considered to be original.

The purpose of this paper is to examine the use of phragmites australis ash (PAA) in cementitious systems to achieve sustainable construction.

Abstract

Purpose

The purpose of this paper is to examine the use of phragmites australis ash (PAA) in cementitious systems to achieve sustainable construction.

Design/methodology/approach

In this paper, the properties of mortar containing PAA as partial cement replacement are determined. The PAA is produced through slow burning in a closed system to minimize the CO2 emission. A total of four mortar mixes are prepared with PAA replacement levels ranging from 0% to 30% by weight. The water to binder and the proportions of binder to sand are 0.55 and 1:3 by weight, respectively. The properties tested are density, compressive strength, flexural strength, ultrasonic pulse velocity, water absorption by total immersion and capillary rise. Testing is conducted at 1, 7, 28 and 90 days.

Findings

While there is a decrease in strength as the amount of PAA increases, there is strong indication of pozzolanic reaction in the presence of PAA. This is in agreement with the results reported by Salvo et al. (2015), where they found noticeable pozzolanic activities in the presence of straw ash, which is rich in SiO2 and relatively high K2O content. At 90 days of curing, there is a decrease of 5% in compressive strength at 10% PAA replacement. However, at 20% and 30% replacement, the reduction in compressive strength is 23% and 32%, respectively. The trend in flexural strength and ultrasonic pulse velocity is similar to that in compressive strength. The water absorption by total immersion and capillary rise tends to increase with increasing amounts of PAA in the mix. There seems to be a linear relationship between water absorption and compressive strength at each curing age.

Research limitations/implications

The Phragmites australis plant used in this investigation is obtained from one location and this present a limitation as the type of soil may change the properties. Also one method of slow burning is used. Different burning methods may alter the composition of the PAA.

Practical implications

This outcome of this research will contribute towards sustainable development as it will make use of the waste generated, reduce the amount of energy-intensive cement used in construction and help generate local employment in the area where the Phragmites australis plant grows.

Originality/value

To the best knowledge of the authors, the ash from the Phragmites australis plant has not been used in cementitious system and this research can be considered original as it examines the properties of mortar containing PAA. Also, the process of burning in a closed system using this material.

Abstract

Purpose

The destruction of armed confrontations – ranging from chronic armed conflicts to full-scale wars – leads to enormous loss of human lives and causes wide-scale devastation. They also leave deep and lasting traumas in the minds of those whose lives are torn apart because of a conflict. Memorialisation of conflict-affected sites plays an invaluable part in post-trauma recovery and can contribute to the reconciliation of different groups involved in a conflict as these sites are representatives of communities' collective memory, identity and a source of unity and resilience. This paper aims to investigate post-trauma recovery and reconciliation processes through the phenomena of memorialisation. It aims to answer how and if the memorialisation of sites of pain can contribute to the recovery and reconciliation of affected communities and serve as examples for other people around the world.

Design/methodology/approach

The documentation of such processes and the lessons learnt can offer valuable information for conducting similar exercises in other settings ravaged by a conflict. To achieve this, a review of literature on trauma, memory, memorialisation and difficult heritage was conducted, while the memorialisation processes from different cases such as Hiroshima and Nagasaki (1939–1945), Beirut (1975–1990) and Sarajevo's Vijecnica and Mostar Bridge (1992–1995) were analysed.

Findings

It was identified that the potential of memorialisation for post-trauma recovery and reconciliation is vast. However, if these processes can “heal” or “hurt” depend largely on who the stakeholders are; how the site and events are interpreted and presented; how pre/post-conflict relationships and dynamics are harnessed; how symbolic meanings (old and new) are [re]interpreted; the spatial-temporal nature of the site and those interacting with it; and the intended and perceived messages. Altogether, memorialisation of conflict-affected sites is a political and continuous process that should take into consideration all those directly and indirectly involved, the dynamics between them and all the symbolic meanings acquired and attributed to the site.

Originality/value

The study critically explores frameworks of memorialisation and their impact on both the built environment and communities. It contributes to the wider discussion of difficult heritage memorialisation and approaches to reflect on sites and cities emerging from crises such as conflict.

This study aims at investigating the effect of bolt hole-making processes on the post-fire behavior of S235 steel plates.

Abstract

Purpose

This study aims at investigating the effect of bolt hole-making processes on the post-fire behavior of S235 steel plates.

Design/methodology/approach

A total of nine steel plates with a single bolt hole are tested. The single bolt holes are fabricated using three different hole-making processes: drilling, waterjet and plasma. Among the nine steel plates, three fabricated specimens are control specimens and are tested at ambient temperature. The six remaining steel plates with a single bolt hole are subjected to a complete heating-cooling cycle and then monotonically loaded until failure. The six fabricated specimens are first heated up to two different temperatures 800 and 925 °C, and then cooled back to the ambient prior to loading.

Findings

The results show that after being exposed to post-fire temperatures (800 and 925 °C), the maximum decrease in strength of the S235 steel plate was 6% (at 925 °C), 14% (at 925 °C) and 22% (at 800 °C) when compared to the results of ambient specimens for waterjet, drilled and plasma bolt holes, respectively. For post-fire temperature tests, drilled and waterjet bolt hole-making processes result in having approximately the same load-displacement response, and both have larger strength and ductility than those obtained using plasma cutting.

Originality/value

This study provides preliminary data to guide the steel designers and fabricators in choosing the most suitable hole-making process for fire applications and to quantify the post-fire reduction in capacity of S235 plates.

Abstract

Purpose

The purpose of this study is to explore the human resource development (HRD) implications of perceived higher education (HEd) leadership effectiveness on academics’ quality of worklife (QWL) in the context of COVID-19. Drawing on conservation of resource theory, this study explains the mediating role of resource adequacy (RA); then this study investigates the moderating role of COVID-19-related risk perception (CRP) on the relationship between university leadership (UL) and both academics’ turnover intention (TI) and academics’ QWL.

Design/methodology/approach

This study used a quantitative research exploiting the pandemic experiences and perceptions survey, PEPS, to collect data from 300 academic staff in private and public HEd institutions in Lebanon. The analyses include the test of the mediating effect of RA as well as the moderated mediation effect of CRP through regressions, PROCESS and bootstrapping.

Findings

The findings suggest that by enhancing RA, effective UL positively influences the QWL and mitigate the TI in Lebanese HEd. Furthermore, this study found that CRP weakens the direct relationship of UL on RA and the indirect effect of UL on the QWL and TI via RA such that the relationships are weakened when COVID-19 risk perception was high rather than low.

Practical implications

The results imply that HEd HRD professionals could think of effective human resource interventions of how to maintain good working environment where academics are facilitated to acquire high level of resources which lead to improving their QWL and mitigating the negative outcome (TIs).

Originality/value

To the best of the authors’ knowledge, no research has been made to investigate the moderated mediation model of the “pandemic experience and leadership perceptions” (PEPS) in the HEd sector in Lebanon, addressing academics’ experiences in business schools. This study is unique because it was conducted during the utmost pandemic outbreak (mid academic year 2021) collecting data in real time. This research contributes to the HRD literature by showing empirical evidence of the relationships in the context of Lebanese HEd institutions.

Abstract

Purpose

Image segmentation is one of the most essential tasks in image processing applications. It is a valuable tool in many oriented applications such as health-care systems, pattern recognition, traffic control, surveillance systems, etc. However, an accurate segmentation is a critical task since finding a correct model that fits a different type of image processing application is a persistent problem. This paper develops a novel segmentation model that aims to be a unified model using any kind of image processing application. The proposed precise and parallel segmentation model (PPSM) combines the three benchmark distribution thresholding techniques to estimate an optimum threshold value that leads to optimum extraction of the segmented region: Gaussian, lognormal and gamma distributions. Moreover, a parallel boosting algorithm is proposed to improve the performance of the developed segmentation algorithm and minimize its computational cost. To evaluate the effectiveness of the proposed PPSM, different benchmark data sets for image segmentation are used such as Planet Hunters 2 (PH2), the International Skin Imaging Collaboration (ISIC), Microsoft Research in Cambridge (MSRC), the Berkley Segmentation Benchmark Data set (BSDS) and Common Objects in COntext (COCO). The obtained results indicate the efficacy of the proposed model in achieving high accuracy with significant processing time reduction compared to other segmentation models and using different types and fields of benchmarking data sets.

Design/methodology/approach

The proposed PPSM combines the three benchmark distribution thresholding techniques to estimate an optimum threshold value that leads to optimum extraction of the segmented region: Gaussian, lognormal and gamma distributions.

Findings

On the basis of the achieved results, it can be observed that the proposed PPSM–minimum cross-entropy thresholding (PPSM–MCET)-based segmentation model is a robust, accurate and highly consistent method with high-performance ability.

Originality/value

A novel hybrid segmentation model is constructed exploiting a combination of Gaussian, gamma and lognormal distributions using MCET. Moreover, and to provide an accurate and high-performance thresholding with minimum computational cost, the proposed PPSM uses a parallel processing method to minimize the computational effort in MCET computing. The proposed model might be used as a valuable tool in many oriented applications such as health-care systems, pattern recognition, traffic control, surveillance systems, etc.

Abstract

Purpose

Faculty play a unique role in universities performing duties along the three fronts of teaching, research and service. While it might be teaching that contributes most to the bottom line of a small university, it is often research by which faculty merit is judged. This study explores the relationships between role ambiguity, role conflict and commitment (affective, normative and continuance) as mediated by job satisfaction among faculty members.

Design/methodology/approach

A sample of 133 faculty members at a US-accredited university in Lebanon served as the basis for this study. The faculty members completed a survey covering scales on role ambiguity, role conflict, commitment and job satisfaction in addition to demographic variables.

Findings

We find that a decrease in role ambiguity strengthens affective and normative commitment but weakens continuance commitment. Structural equation modeling indicates that job satisfaction partially mediates the relationship between role ambiguity and affective commitment, while not mediating the relationship between role ambiguity and normative and continuance commitments. Similar findings hold for job satisfaction as a mediator in the relationship between role conflict and commitment.

Originality/value

Based on statistical modeling, this work (1) puts forth a revised scale for organizational commitment tailored to academia and (2) provides guidance to higher education institutions in terms of the differential impacts on faculty commitment that stem from reducing role-ambiguity versus role-conflict. Managerial recommendations focus on improving normative and affective commitment through the design of policies to reduce role conflict among faculty.

Abstract

Purpose

This paper aims at shedding light on the entrepreneurs' perception towards crowdfunding as a new mean for raising capital, and their willingness to send appropriate signals to the potential fund providers/backers.

Design/methodology/approach

The research strategy is based on three methodological approaches: desk research on online sources, a map of the crowdfunding phenomenon, and a quantitative approach with a survey performed between June and December 2020. The survey covers a sample of 147 Small and Medium enterprises (SMEs) and startups, in addition to semi-structured interviews with 10 entrepreneurs.

Findings

The study reveals that between losing their work and losing part of their firms' equity, entrepreneurs are keen on sending positive signals to backers. Moreover, they are willing to adopt a new way of thinking, as their primary goal is to save their firms, their jobs, and their source of income. The research highlights the concern of entrepreneurs of losing reputation, losing intellectual property, losing control, and of becoming only shareholders in their enterprises.

Research limitations/implications

The main limitation in this paper is that no single study in Lebanon adequately covers the topic and thus extensive research has been carried out on crowdfunding across the world and analyzed in the Lebanese context.

Practical implications

Overcoming funding challenges can reduce brain drain, promote a culture of entrepreneurship, serve the economy, combat poverty, achieve more equitable society, increase the levels of expectations, and turn the flywheel. Moreover, the paper presents clear implications for the field of policy-making both in developing and developed countries.

Originality/value

Considering the serious financial disintermediation and liquidity shortage Lebanon faces, the findings of this study show how important changing entrepreneurial culture and behavior is, and the crucial role crowdfunding could play in providing funds for the SMEs that form 95% of the total business sector in Lebanon.
