An atomic commit protocol can cause long-term locking of databases if the coordinator crashes or becomes disconnected from the network. In this paper we describe how to eliminate the coordinator. This decentralized, cooperative atomic commit protocol piggybacks transaction statuses of all transaction participants onto tokens which are passed among the participants. Each participant uses the information in the tokens to make a decision of when to go to the next state of a three-phase commit protocol. Transactions can progress to ensure a uniform agreement on success or failure, even if the network is partitioned or nodes temporarily crash.

Purpose The purpose of this study is to examine the impact of coronavirus disease 2019 (COVID-19) on indigenous contractors in a developing economy with a view to enhancing their performance. Design/methodology/approach The study used a purposive sampling technique to select 37 indigenous contractors with ongoing construction contracts in Osun State, Nigeria who provided data for the study. A structured interview protocol was used to elicit the required information from the interviewees and frequency, percentage and content analysis were used for data analysis. Findings The results showed that the critical impact of COVID-19 on indigenous contractors in a developing economy is: time overrun, loss of profit and creation of dispute. Further results showed that other impacts are a disruption in supply of labour, locally sourced materials are with additional cost, the additional cost of implementing COVID-19 protocols, difficulty in sourcing imported materials and absence of new jobs with the corresponding retrenchment of workers. Practical implications The study recommended special palliatives for the indigenous contractors from the government so as to cushion the impact of the pandemic on them, thereby enhance their survival and performance. A special arbitration panel is set up in each state of the federation to look at disputes arising from the aftermath of the pandemic, this is with a view to adequately compensate indigenous contractors with genuine and properly compiled claims. inferring from the findings of the study, it suffices to say that the severity of the impact of the pandemic is very high on indigenous contractors in developing economies, as such a better preparedness strategy could lessen the impact of such pandemic in the future. Originality/value The study is an attempt to unearth the impact of COVID-19 on indigenous contractors with ongoing construction contracts in a developing economy. The study will be of value to construction stakeholders in providing the information needed to devise strategies to minimise the impact of a pandemic on indigenous contractors in future projects thereby enhance their performance.

Posidonia oceanica leaves (seagrass) are collected almost in all the Mediterranean seashores as spoils and disturbing material with additional cost for removal from the coastline. Seagrass, however, is known for its interesting properties, such as decay, fire and moisture resistance as well as insulation. Research for using this material in composing boards was initiated. This study looks into the possibility of using these waste marine plants for the production of alternative building material in the form of pressed panels. The paper describes the pretreatment of seagrass leaves before their processing for composite boards and the examination of its final product. The residence time for salts desorption was also determined. The main processes analyzed were the binder spraying and panel forming. Mechanical properties were evaluated by the standardized flexural tests. In addition, swelling properties were investigated. Results obtained from testing and observation of boards indicated that seagrass leaves are propitious for the application in construction and furniture industry.
