While previous research in career studies has highlighted the positive impact of several leadership behaviors on followers’ work and career success, less is known about how the emergent topic of inclusive leadership shapes followers’ task performance. Using an inclusive leadership approach and job demands-resources theory, we developed a novel sequential mediation model in which inclusive leadership indirectly facilitates followers’ performance through self-initiating behavior and work motivation. Specifically, we aimed to investigate whether inclusive leaders encourage followers to show enhanced task performance through strengths use and work engagement.

A representative sample of 278 Dutch employees from diverse organizations was surveyed at three different time points.

The results of structural equation modeling evidenced that inclusive leadership was indirectly related to follower task performance, initially through the utilization of strengths and subsequently through work engagement over time. When leaders exhibited behaviors that were inclusive in nature, they encouraged their followers to make use of their strengths at work. Such leadership actions boosted the work engagement of their followers and led to enhanced task performance.

We develop and test a novel sequential mediation model that explores how inclusive leadership fosters improved task performance among followers by promoting the utilization of strengths and subsequent work engagement. This sheds light on the mechanisms through which inclusive leadership contributes to follower performance, a crucial indicator in shaping sustainable career trajectories.

Strengths-based professional development has been associated with positive outcomes in academia and in the organizational workplace. Students pursuing their doctoral degrees in the biomedical sciences in the US are often on graduate assistantships, where they experience an academic component to their training integrated with an employee-like existence. The individual who serves as their academic and research advisor is often their supervisor, who pays their stipend. The traditional training structure poses unique challenges and may be accompanied by stress, burnout and imposter phenomenon. The purpose of this study is to utilize a strengths-based approach to equip students with essential personal and professional skills that build self-awareness and self-confidence further preparing them for their future in the scientific workforce.

The authors developed and implemented a novel strengths-based professional development cohort program for doctoral students in the biomedical sciences at a research-intensive (R1) institution. The program was designed to create a supportive and inclusive space for participants (n = 18) to explore their identity as a student and scientists and to develop and leverage their talents for more effective and strategic use. Program outcomes were evaluated through a mixed methods case study design using a post-program Likert-based survey (n = 10 participants) and participant interviews (n = 13). Explanatory sequential design was used in the interpretation of the findings.

The results show that the program had a positive impact on students’ perceptions of themselves as scientists, as well as on their self-efficacy, self-confidence and interpersonal interactions in the research setting.

This strengths-based professional development program demonstrates immense potential as a model to equip students with self-awareness and a new foundation of essential skills needed to supplement their technical and scientific training for their future careers in the team-based workplace.

This study demonstrates how professional development programming can complement scientific training by equipping students with self-awareness and other lifelong skills to navigate feelings of imposter phenomenon and interpersonal relationships in the team-based workplace.

One of the often-employed building constituents in the construction sector is concrete, which involves hydration of cement, leading to the generation of carbon footprints during its production. Also, massive amount of natural aggregate is illegally mined, which poses serious environmental issues along with ecological misbalance. Researchers are in continuous search of appropriate substitutes to mitigate those challenges and develop innovative concrete mix. Consequently, depletion of natural resources, the disturbances to the environmental and ecological imbalance will reduce. The purpose of this study is to develop a Portland Slag Cement based novel sustainable concrete incorporating Alccofine and Recycled Refractory Brick as fractional replacement of cement and fine aggregate, respectively and evaluate its destructive, non-destructive and microstructural properties.

M25 grade of concrete adopting 0.45 water-binder proportion, with diverse percentage of Alccofine as fractional substitution of cement and 20% of recycled refractory brick (RRB) as fine aggregate, has been cast and evaluated for diverse mechanical strength following a curing of 7, 14 and 28 days. Scanning electron microscopic analysis has been carried out to study the microstructural changes in the specimens.

Supplementary use of Alccofine enhanced normal compressive strength of sustainable concrete mix blended with Portland Slag Cement by a large amount at all levels of 7, 14 and 28 days of curing. Test results indicated development of a favourable high-strength sustainable concrete mix by substituting cement with Alccofine.

This manuscript has demonstrated the possibility of developing sustainable concrete blends by incorporating Alccofine 1203 and RRB as partial replacement of Portland Slag Cement and natural fine aggregate, respectively. The strength and potential of concrete incorporating RRB for wider and special application in adverse environmental conditions having higher thermal gradient, as RRB is a valuable waste from high temperature kiln and furnaces. Alccofine 1203 has been included in the concrete mix as an alternative to Portland Slag Cement to improve the mechanical strength properties and durability of concrete intended for adverse environmental application.

This paper aims to investigate the bond strength of metakaolin-based geopolymer mortar with cement mortar.

The mortar-mortar bond strength is assessed by slant shear and split tensile tests; pure shear strength is evaluated by Mohr’s criterion for result validation. Metakaolin-based geopolymer mortar is cast over the cured cement mortar specimen with two levels of surface roughness: smooth or grooved interface. The influence of the alkaline solution to metakaolin ratio on geopolymer bond strength is studied. Compressive strength, ultrasonic pulse velocity, permeability and flow table tests are also performed.

The paper’s findings are highlighted as follows: (1) strong mortar-mortar bond properties achieved for geopolymer mortar in all tests and conditions and validated by Mohr’s criterion and pure shear, (2) a lower alkaline solution to metakaolin ratio achieves higher bond strength to Portland cement mortar and (3) geopolymer mortar has higher compressive strength and ultrasonic pulse velocity than cement mortar at all curing ages; additionally, it is more flowable and less permeable.

The full replacement of Portland cement with metakaolin, a more sustainable cementitious material, will contribute to the decarbonization of the construction industry.

Limited research has been carried out on the bond strength of metakaolin-based geopolymer mortar to Portland cement mortar. Also, computing the pure shear using Mohr’s circle criterion of metakaolin-based geopolymer to validate the results can be considered original.

This study aims to investigate the relationships between various frontline management (FLM) styles, human resource management system (HRM) system strength and employees' helping behaviours as a form of organisational citizenship behaviours (OCBs). The research also examines the moderating role of workgroup loyalty in the association between HRM system strength and employees' helping behaviours.

The research uses survey data collected from 315 government workers in Malaysia. Structural equation modelling (SEM) was employed to test the hypothesised relationships.

Two FLM styles, “policy enactor” and “employee coach,” positively predict employees' helping behaviour. However, the “organisational leader” FLM style did not significantly lead to employees' helping behaviour. HRM system strength significantly mediates the relationship between the three FLM styles and employee helping behaviours. Finally, workgroup loyalty significantly moderates the relationship between HRM system strength and employees’ helping behaviours as OCB.

With a wealth of literature demonstrating the importance of FLMs in the implementation of HRM and a growing body of literature demonstrating the robust nature of the “system strength” argument, human resource (HR) practitioners are increasingly able to focus their attention on the way the system and FLMs contribute to employee outcomes and organisational performance. Our results indicate that HRM system strength does indeed enhance the impact of FLM styles on employee helping behaviours.

The originality of this paper is that it acknowledges and empirically examines the heterogenous nature of FLM styles, through signalling theory in enacting HRM policies and links the growing FLM literature to the HRM system strength research. These concepts have also been tested for the first time in a Malaysian context.

The development of high-strength engineered cementitious composite (ECC) gains a significant leap in structural engineering. Engineers have been looking for new formulations that combine outstanding compressive strength with increased flexural resistance. This research focuses on the main characteristics, techniques and prospective applications of high-strength ECC. The proposed work explores the composition of such concrete, emphasizing the use of novel additives, fiber reinforcements and optimal particle packing to produce excellent mechanical characteristics and demonstrating how high-strength ECC contributes to incorporate sustainability by potentially lowering the need for supplemental reinforcing and resulting in a lower environmental effect.

This research involves on studying the composition of high-strength ECC and geopolymer-based ECC, the use of novel additives, fiber reinforcements and optimal particle packing. It examines the capacity of high-strength ECC to sustain high loads with an allowable deformation without any catastrophic collapse. It discusses the sustainability aspects of high-strength ECC and its potential alternative as geopolymer-based ECC.

High-strength ECC offers an excellent compressive strength while also providing increased flexural capacity. Employment of copper slag (CS) as a filler material for the production of ECC results in 28.92% lower cost, when compared to the mix developed using conventional river sand. Whereas in the case of geopolymer-based ECC, the cost of production was found to be 31.92% lower than that of the conventional.

High-strength ECC is developed using conventional river sand and industrial by-product, CS as a filler material. The combination of achieving higher compressive strength with an increased use of industrial by-products leads to the development of sustainable high strength ECC. The potential use of high-strength ECC reduces the need for supplementary reinforcing and increases the structural lifetime, resulting in a lower environmental impact.

While the career literature does acknowledge that personal strengths may function as protective factors that increase the likelihood of positive career outcomes, the topic of strengths has predominantly been studied in the context of career guidance for adolescents and young adults. However, the evolution of strengths persists throughout the entire career and individuals’ awareness and inclination to leverage their strengths change when aging. This paper aims to examine strengths over the (career) lifespan.

For this purpose, a conceptual analysis was made of the interplay between age and strengths application within the work environment, based on a narrative review of both empirical and conceptual literature on strengths and lifespan (career) development.

Based on lifespan development theory and results from studies that investigate the relationship between age and strengths, it can be expected that the prominence, awareness and use of strengths, as well as the active engagement in strengths development increase with age. Also, based on the corresponsive principle it is proposed that strengths prominence is reciprocally related to the awareness, use and development of strengths. Implications for future research and practice are discussed.

Whereas positive psychology has contributed to research on career development by its focus on healthy functioning, human potential and well-being the implications from theorizing and research on strengths for the career-lifespan are still relatively unclear. This paper develops testable propositions regarding the relationship between age and strengths and discusses implications for the types of organizational support for strengths that workers of different ages might need.

This study was aimed at clarifying the post-fire shear strength of self-drilling screws and the load-bearing capacity of single overlapped screwed connections using steel sheets and self-drilling screws. The self-drilling screws for shear tests were made of high-strength, martensitic-stainless and austenitic stainless-steel bars.

Shear loading tests were conducted on self-drilling screws to obtain basic information on post-fire shear strength. Tensile tests were conducted on the screwed connections to examine the transition of failure modes depending on the test temperature after experiencing the heating and cooling procedures.

The post-fire shear strengths and reduction factors of self-drilling screws of each steel grade were quantified. Furthermore, heated temperature-dependent sheet bearing failure, net sheet failure and screw shear failure modes were observed for the screwed connections.

The transition of the failure modes of the screwed connection could be explained using the equations of the post-fire shear strength proposed in this study. The basic experimental data required to evaluate the post-fire shear strength of screws were obtained.

This paper aims to clarify the efficient process of the machine learning algorithms implemented in the ready-mix concrete (RMC) onsite. It proposes innovative machine learning algorithms in terms of preciseness and computation time for the RMC strength prediction.

This paper presents an investigation of five different machine learning algorithms, namely, multilinear regression, support vector regression, k-nearest neighbors, extreme gradient boosting (XGBOOST) and deep neural network (DNN), that can be used to predict the 28- and 56-day compressive strengths of nine mix designs and four mixing conditions. Two algorithms were designated for fitting the actual and predicted 28- and 56-day compressive strength data. Moreover, the 28-day compressive strength data were implemented to predict 56-day compressive strength.

The efficacy of the compressive strength data was predicted by DNN and XGBOOST algorithms. The computation time of the XGBOOST algorithm was apparently faster than the DNN, offering it to be the most suitable strength prediction tool for RMC.

Since none has been practically adopted the machine learning for strength prediction for RMC, the scope of this work focuses on the commercially available algorithms. The adoption of the modified methods to fit with the RMC data should be determined thereafter.

The selected algorithms offer efficient prediction for promoting sustainability to the RMC industries. The standard adopting such algorithms can be established, excluding the traditional labor testing. The manufacturers can implement research to introduce machine learning in the quality controcl process of their plants.

Regarding literature review, machine learning has been assessed regarding the laboratory concrete mix design and concrete performance. A study conducted based on the on-site production and prolonged mixing parameters is lacking.

The purpose of this study was to examine how well a strength-based program grounded in positive psychology principles can advance the practical critical thinking skills of those pursuing the teacher training course.

This study used a single-group pre-test post-test design with 35 teacher-trainees from the Bachelor of Education course. The two-and-a-half-week strength-based program used the values in action survey to identify strengths. Pre- and post-test scores, measured with the Cornell Critical Thinking Test – Level Z, underwent Statistical Package for Social Sciences analysis including paired samples t-test for subcomponent and overall composite analysis.

Analysis of the pre- and post-test scores demonstrated a statistical significance in the critical thinking scores obtained by the teacher-trainees. Post-test scores were consistently significant. Out of the elements of critical thinking, induction, meaning, observation and credibility were more prominent. Deduction and assumption identification were also having a significant effect.

Most critical thinking programs focus on evaluating specific teaching methods for improving critical thinking skills. In education, positive psychology studies often center on students’ well-being, attention spans and academic success, aligning with wellness programs. Despite the importance of strengths in positive psychology, there is a lack of research on using a strength-based approach to boost critical thinking skills. This study aims to enhance teacher-trainees’ critical thinking by leveraging their individual strengths, moving away from traditional instructional strategies.
