INHIBITORS. Effect of additives on protective properties of effluent of coke by‐product It was found that the waste water or effluent of a coke by‐products factory contains substances having protective properties in neutral media. Inhibitors such as the Russian KKh (coke over by‐product) have been prepared from such. In the present work the effect of various additives has been investigated. Test samples used were of carbon and low‐carbon steels. They were thoroughly degreased and polished with emery paper, then placed in a desiccator with sulphuric acid for some days. The tests were made at room temperature in media of pH 5 to 8. Rate of corrosion was determined by the weight method; in addition to which the adsorption of ions at the surface of the corroding metal was also studied with the use of radioactive isotopes, P32, S35 and Ca45. The results are recorded and tabulated under the headings: effect of certain passivators, of carbon dioxide, of various chemical additives and of ion adsorption. Carbon dioxide was found to be a very effective additive; also zinc sulphate. It is proposed therefore that, in order to reduce boiler scale and corrosion, the KKh‐1 (effluent) should be treated with carbon dioxide and used as return water in water‐cooling systems of coke by‐product factories.

Analyses the economic system slice‐wise, taking the main economic activities for a year together. Within this slice the development of the economic activities is characterized by plus or minus signs according to an increase or decrease of the activities. This yearly sequence of plus and minus signs is taken as a pattern. Analyses these economic patterns according to cybernetic and economic criteria. Sign‐equivalent patterns are taken together as groups. The chronological development of these groups gives the profiles of the economy. The development of profiles is quite concordant with the business cycle of the economy in question.

Studies show that the twenty-first-century construction industry needs reskilling and upskilling tools to train large numbers of the workforce for better-integrated project delivery. Evidence shows that digitisation via the fourth industrial revolution (4IR) technology can play a critical role in reskilling and competency demand. Attempting to use digital technology may have had some challenges. Studies about the perceived hindrances facing Nigeria's built environment professionals (BEP) reskilling and upskilling needs in the workplace via 4IR technologies are scarce. Thus, the study investigated the perceived encumbrances facing Nigeria's BEP training needs and proffered measures to improve their performance in the workplace via 4IR technologies.

The researchers engaged BEP in Lagos and Abuja, Nigeria. Regarding the data collection, a qualitative research design was adopted. The study achieved saturation after 32 virtual interviews. A thematic analysis was adopted for the collected data.

The study shows that using 4IR for reskilling and upskilling will enhance integrated project delivery. But the level of usage in training needs is low. Findings identified the various ways reskilling and upskilling could be achieved. Also identified are the major built environment areas that require 4IR training. Findings highlighted possible encumbrances facing the use of 4IR technologies by Nigerian BEP for reskilling and upskilling needs in the workplace and proffered feasible measures to improve 4IR usage for training needs.

The study is restricted to the perceived encumbrances and proffers measures to improve BEP reskilling and upskilling needs via 4IR technologies via a qualitative method. Future research is required to validate the findings and test the proposed framework that emerged from the study.

The study confirms that reskilling and upskilling measures are required at all skill levels and may lead to economic growth. The paper would advance Nigerian higher educational accreditation agencies and various BEP regulatory bodies to review the curriculum and incorporate 4IR as a component or module.

The thematic network analysis and proposed framework could be utilised to stimulate Nigeria's BEP reskilling and upskilling needs in the workplace via 4IR technologies. It would stir main stakeholders, especially government policymakers, to facilitate programmes to improve 4IR technologies usage.

Research on transparency has been concerned mainly with external transparency, leaving internal transparency understudied. In particular, there is a lack of empirical research on the relationship between internal transparency and organizational resilience. This paper aims at investigating how internal transparency impacts organizational resilience in a public entity. It also examines how (quality) management systems impact internal transparency, and thus organizational resilience.

The research is based on semi-structured interviews covering the relevant topics. A total of 32 interviews were undertaken between January and May 2018.

The findings indicate that internal transparency contributes to better preparedness to adverse conditions by enhancing the ability to cumulate, locate and share knowledge. Similarly, management systems improve internal transparency through the enhancement of communication flow, use of indicators and accretion of a database.

The paper is the first, as evident from the literature review, to investigate how internal transparency impacts organizational resilience. Hence, it sheds light on a very important aspect of the effective management of quality, risk and reliability. It is also one of the first papers to examine the mediating role of (quality) management systems in organizational resilience.

The objective of this study was to extend prior research by examining subordinate–superior information asymmetry as an intervening variable linking budgetary participation and slack. The results indicate two offsetting effects of participation on slack. A significant negative indirect relation between participation and slack was found to act through information asymmetry. Thus, managers reveal private information during the budget process, reducing information asymmetry which subsequently reduces budget slack. These results provide evidence about the inability of past research to confirm a consistent direct relation between budget participation and budget slack.

The author describes a quick and reliable method of testing rust preventives which employs chemicals tagged with radioactive tracers. He includes also a note on handling and health hazards so that the necessary precautions can be taken when using the technique.

The purpose of this paper is to identify, classify and analyse temporality in information systems development (ISD) literature.

The authors address the temporality and ISD research gap by using a framework – which classifies time into three categories: conceptions of time, mapping activities to time and actors relating to time. The authors conduct a systematic literature review which investigates time in ISD within the Senior Scholars' Basket, Information Technology & People (IT&P), and top two information systems conferences over the past 20 years. The search strategy resulted in 9,850 studies of which 47 were identified as primary papers.

The results reveal that ISD research is ill equipped for contemporary thinking around time. This systematic literature review (SLR) contributes to ISD by finding the following gaps in the literature: (1) clock time is dominant and all other types of time are under-researched; (2) contributions to mapping activities to time is lacking and existing studies focus on single ISD projects rather multiple complex ISD projects; (3) research on actors relating to time is lacking; (4) existing ISD studies which contribute to temporal characteristics are fragmented and lack integration with other categories of time and (5) ISD methodology papers lack contributions to temporal characteristics and fail to acknowledge and contribute to time as a multifaceted interrelated concept.

This work has developed the first SLR on temporality in ISD. This study provides a starting point for ISD researchers and ISD practitioners to test commonly held temporal assumptions of ISD researchers and practitioners.

In less than a decade to sustainable development goals (SDGs) there is a threat of household waste emanating from sub-urban sprawl especially in developing countries. Private approaches with government-enabling environments have been proved a successful platform for urban services such as housing provision and telecommunication in developing cities. Still private solid waste management (PSWM) seems different in Nigeria. Therefore, this paper aims to investigate the possible perceived hindrances facing PSWM organisations and proffer feasible policies to enhance sustainable clean and healthy cities.

Seven communities within Benin City sub-urban environs were adopted as the study area to accomplish the research’s objectives via a phenomenology type of qualitative research design. The study analysed the collated data from the knowledgeable participants via a thematic approach.

Lax legislative, absence of institutional framework, inadequate economic motivation, inadequate technical operations, among others, emerged as the encumbrances faced by PSWM firms. Wastes dumped along unethical locations such as streets, roads, uncompleted buildings, culverts and drainage channels, and undeveloped plots emerged as the encumbrance outcomes. Findings show that proffering feasible policy solutions to tackle identified hindrances can promote the achievement of SDGs across semi-urban locations in Nigeria.

This research is restricted to urban household waste management by PSWM within Nigeria. Also, the study identified the challenges and proffer policy solutions to enhance improved clean environment within the sub-urban and urban cities.

As part of this study’s implications, results from this research intend to guide government policymakers and PSWM firms to encourage collaboration in designing appropriate strategic and educational programmes for the householders (customers) in sub-cities. It will be achieved via feasible policies that are tailored towards achieving sustainable health and environment-friendly sub-urban locations.

This paper intends to enhance proper PSWM and create sustainable cities via collaboration. Also, the paper engaged key stakeholders via a qualitative research design to proffer possible solutions to the menace of sub-urban and urban household waste management.

Globally, prefabrication in housebuilding has evolved as an innovative approach to attain sustainability and affordability. However, the SC, including non-producers and producers, of prefabricated housebuilding projects is still not perceptually aligned, hindering innovation diffusion. This paper investigates the contemporary industry perspective on PHB for conceptualisation, market share and growth, innovation diffusion and the producer's role in the context of New Zealand.

An exploratory qualitative research design was chosen to learn the perceptual stance of the industry. A semi-structured survey was conducted, followed by interviews with selected supply chain participants, who were producers and non-producers and had relevant experience in the PHB industry.

This study reports the common terminologies used by supply chain members, with justification and explanation. Further, the perceived market share and growth of the PHB industry are obtained and compared with subsequent studies to determine the capability and capacity. The perception of the diffusion of PHB by type is reported to portray the overall trend of the industry. In the last, the role of producers as the suppliers of PHB projects is investigated to establish the stakeholder positional criticality.

This study can help researchers and practitioners gain insight into the PHB industry from a multi-dimensional perspective. This study is a potential first step to formalise the policy, programme, strategies and action plan for the uptake of the PHB in the New Zealand.

PHB diffusion in the supply chain perspective, considering multi-dimensional aspects, has not been considered in previous studies as government agencies produce most of the literature. This academic research establishes the theoretical linkage towards PHB diffusion and reports the current status.
