Abstract
Purpose
This research proposes a viable method of slab and shore load computation for the partial striking technique utilized in high-rise construction projects to optimize the use of horizontal formwork. The proposed Partial Striking Simplified Method (PSSM) is designed to be utilized by industry practitioners to schedule the construction operations of casting floors in order to control the formwork costs incurred throughout the completion of a project.
Design/methodology/approach
The article presents the PSSM for calculating slab and shore loads in multi-story building construction. It introduces the concept of “clearing before striking,” where shore supports are partially removed after a few days of pouring fresh concrete. The PSSM procedure is validated through numerical analysis and compared to other simplified approaches. Additionally, a user-friendly Python program based on the PSSM procedure is developed to explore the capability of the PSSM procedure and is used to study the variations in slab load, shoring level, concrete grade and cycle time.
Findings
The study successfully developed a more efficient and reliable method for estimating the loads on shores and slabs using partial striking techniques for multi-story building construction. Compared to other simplified approaches, the PSSM procedure is simpler and more precise, as demonstrated through numerical analysis. The mean of shore and slab load ratios are 1.08 and 1.07, respectively, which seems to have a slight standard deviation of 0.29 and 0.21 with 3D numerical analysis. The Python program developed for load estimation is effective in exploring the capability of the proposed PSSM procedure. The Python program's ability to identify the floor under maximum load and determine the specific construction stage provides valuable insights for multi-story construction, enabling informed decision-making and optimization of construction methods.
Practical implications
High-rise construction in Indian cities is booming, though this trend is not shared by all the country's major metropolitan areas. The growing construction sector in urban cities demands rapid construction for efficient utilization of formwork to control the construction costs of project. The proposed procedure is the best option to optimize the formwork construction cost, construction cycle time, the suitable formwork system with optimum cost, concrete grade for the adopted level of shoring in partaking and many more.
Originality/value
The proposed PSSM reduces the calculation complexity of the existing simplified method. This is done by considering the identical slab stiffness and identical shore layout for uniform load distribution throughout the structure. This procedure utilizes a two-step load distribution calculation for clearing phase. Initially, the 66% prop load of highest floor level is distributed uniformly over the lower interconnected slabs. In the second step, the total prop load is removed equally from all slabs below it. This makes the load distribution user-friendly for the industry expert.

Abstract
Purpose
A recent United Nations (2021) report stated that education needs to be concerned with enhancing human relationships with the natural world if we are to work toward building a sustainable future. This paper proposes that educational practices underpinned by an ecological orientation in mid-century Aotearoa offer insights for educators looking to enhance human connection with nature. It also argues that ecological thinking has implications for how research in the history of education might be carried out.
Design/methodology/approach
The article responds to recent calls in history of education for researchers to attend to the intertwined ecologies of living and material worlds in research approaches by Maria Tamboukou (2020) and Karin Priem (2022). It conducts a close analysis of a 1952 nature diary, encountered in the national archive, written by a 9-year-old pupil on the West Coast of the South Island. The analysis attends to the human–nature interactions the diary records, and to the resonance of the text in the context of post-war curriculum changes.
Findings
Post-war nature study in Aotearoa New Zealand built on an aim to nurture children’s connections with nature and to place. Analysis of an entry from the 1952 nature diary highlights these connections and demonstrates the possibilities for a reframing of human–nature relationships that emerge with an ecological orientation in education. These findings speak to urgent contemporary concerns with environmental sustainability and human–nature relationships.
Originality/value
The paper draws on educational philosophy and theory (Fesmire, 2012; Nicol, 2014) alongside recent conversations in the history of education (Priem, 2022; Grosvenor and Priem, 2022; Tamboukou, 2020) to consider human–nature relationality at the heart of ecological thought. It outlines an approach to archival research that is ecologically oriented, generating openness and receptivity to the material world.

Abstract
Purpose
With the current developments within the sphere of Internet of Things (IoT) technology, many conventional articles are all being fitted with smart functionalities, ranging from chairs, beds, shoes and caps to underwear. Bags which are utility as well as fashion items have not been left out of this smart craze, albeit to a less popular degree. The purpose of this study is to fill the research gap on the subject of smart bags research and applications and to contribute to the general discourse on IoT.
Design/methodology/approach
This study adopts literature search and database review, concept mapping as well as synthesis methodologies. Relevant literature form databases such as Web of Science, Google Scholar and Bing Scholar were interrogated. Manual sifting was done to eliminate papers that do not fit the set inclusion criteria. Literature on smart bags was organized into structured frameworks using concept mapping methodology. Applying a synthesis methodology enabled an exploration of the different technological trends in smart bag research and their areas of application.
Findings
The study identified about 15 different smart bag applications and functionalities. Discussed in this study is a classification of bags based on a number of points such as way of carrying, size, utility and fabrication materials. Also discussed are the description of what constitute a smart bag, relevant technologies for smart bag design and engineering and subsequently the current trends in smart bag applications. This study also discovered that the air travel industry tend to have some difficulties with this smart bag technologies, specifically with their built-in batteries.
Practical implications
The results of this study will provide researchers and other stakeholders with key information about existing problems and opportunities in smart bag research and applications. This will go a long way to help in guiding future research as well as policymaking in smart bag design and application.
Originality/value
To the best of the authors’ knowledge, this is the first review on the subject of smart bags even though smart bag research and commercial product design continue to gain momentum in recent years.
