Abstract
In the UK alone, approximately £2,000 million is spent each year on cutting fluids and oils. This is merely the cost of purchasing the material and does not include the sizeable sum required to pay for disposal of used fluids or any additives needed to support the fluids while in use.

Abstract
This study develops a method to estimate the probability density function of the Federal Risk Management Agency’s (RMA’s) net income from reinsuring crop insurance for corn, wheat, and soybeans. When calibrated using 1997 data, results from the advocated method show that in 1997 there was a 5% probability RMA would have had to reimburse at least $1 billion to insurance companies, and the fair value of RMA’s insurance services to insurance firms in 1997 was $78.7 million.

Abstract
Purpose
In working towards a sustainable campus of public universities, energy consumption behaviour assessment is one of the several issues that requires attention by the facilities manager. Information on energy consumption behaviour is needed to determine potential energy savings. The purpose of this study is to assess energy consumption behaviour for student accommodations in Malaysian public universities.
Design/methodology/approach
This study focuses on developing energy consumption behaviour models (ECBMs) and assesses the potential energy savings. The “energy culture” framework consolidated with multiple regression analysis is used to strengthen the development of ECBMs. A self-administrated survey involving 1,009 respondents in selected public universities was carried out.
Findings
The result shows that five factors from the energy culture framework contribute to energy consumption behaviour, namely, building regulation, environmental concern, education, social marketing and direct factors (device and activities). These factors are included in the model for predicting energy consumption levels. The results show that there is a 78 per cent difference in energy consumption between the observed and predicted data.
Practical implications
This study indicates a high potential energy saving among students of Malaysian public universities.
Originality/value
The model was tested against the overall students among Malaysian public universities. In future, the model can be tested within hostel accommodations. The present assessment revealed the potential energy saving among the hostel buildings and sets the target regarding which building has a potential to reduce energy. It also helps the facilities managers to come up with strategies for programmes and energy policy in public universities.

Abstract
This study estimates the probability density function of the government’s net income from reinsuring crop insurance for corn, wheat, and soybeans. Based on 1997 data, it is estimated there is a 5% probability that the government will need to reimburse at least $1 billion to insurance companies, and that the fair value of the government’s reinsurance services to insurance firms equals $78.7 million. In addition, various hedging strategies are examined for their potential to reduce the government’s reinsurance risk. The risk reduction achievable by hedging is appreciable, but use of derivative contracts alone is clearly no panacea.

Abstract
Purpose
The purpose of this study was to determine the effects of chickpea (Cicer arietinum) protein hydrolysates prepared at two degrees of hydrolysis (DH) on lipoprotein profile and on oxidant status in cholesterol-fed rats.
Design/methodology/approach
Eighteen male Wistar rats (220 ± 10 g) were divided into three groups and fed for 30 days a diet containing 20 per cent casein supplemented with 1 per cent cholesterol and 0.5 per cent cholic acid. During the experimentation, the first and the second groups received daily by gavage 250 mg of chickpea protein hydrolysates/rat at DH = 8 per cent (CPH8) and DH = 17 per cent (CPH17), respectively. The third group, named control group (CG), received water under the same conditions.
Findings
Serum total cholesterol concentrations were reduced in CPH8 (p < 0.0073) and CPH17 (p < 0.0004) groups versus CG. This reduction corresponded to a lower very-low-density lipoprotein (VLDL)-cholesterol (p < 0,0019). CPH17 reduced low-density lipoprotein- and high-density lipoprotein (HDL)-cholesterol (p < 0.0001) but increased apolipoprotein A4 (p < 0.002) concentrations and lecithin-cholesterol acyltransferase activity (p < 0.0001). APOA1 remained unchanged in the treated groups. Liver total and esterified cholesterol contents were twofold lower in both treated groups versus CG. CPH8 increased triacylglycerols and phospholipids (p < 0.0001) contents, while CPH17 decreased those of unesterified cholesterol (p < 0.0016). Compared with CG, CPH8 and CPH17 reduced serum (p < 0.0001) and lipoprotein hydroperoxides by stimulating paraoxonase activity (p < 0.0001). However, only CPH17 treatment reduced serum, VLDL- and HDL-malondialdehyde contents and improved glutathione peroxidase activity (p < 0.061).
Originality/value
Thus, chickpea protein hydrolysates and especially hydrolysed at DH = 17 per cent may have a great potential for use as a nutraceutical to reduce hypercholesterolaemia and, by consequence, oxidative stress. Therefore, the degree of enzymatic hydrolysis has a significant influence on the production of potent bioactive peptides.

Abstract
WE have now to regard Indexing from quite another standpoint. Hitherto we have been assuming it to be undertaken from a co‐operative point of view, as in the case of Poole's Index and also in that of the Review of Reviews. In special work, the greater the magnitude of the task, as in the instance of Science as a whole, and any large divisions of Science, the more likely is co‐operative effort to be required, but speaking generally special indexes are largely the result of individual effort. It is here that that discrepancy in execution, allusion to which has been made earlier, becomes so manifest. It is my principal object to show how these contradictory methods, the natural result of several minds working on no fixed or settled plan, may be avoided. No space, therefore, will be wasted on detailing these inconsistencies, for the reader's and student's interests will be better served by the more positive method of pointing out how to index on a fixed and settled system. As in the previous section practical illustrations will appear later on to demonstrate this.

Abstract
THE recent Home Office Return showing the names of all places in the British Isles in which the Public Libraries Acts have been adopted, and supplying the statistical information regarding issues, income and expenditure, etc., is an interesting testimony to the extent to which the Public Library has entered into the life of the community. The summary of the statistics (which are for the year ending 31st March, 1911) gives the following results. The population of the places in which the Acts have been adopted is 26,370,582; the total number of volumes in the libraries is 10,995,115 (of which 3,366,549 are in reference libraries); the total issue is 54,690,222; and the total expenditure is £814,932. These figures vary considerably from other recent surveys, but this is caused by the method of compilation of the Return. Duly recorded reference issues are included, for example, and no allowance is made for the millions of unrecorded references. According to this Return there are six library systems in the British Islands issuing over one million volumes per annum. These systems are as follows:—

Abstract
This article examines the work of Carter G. Woodson (1875-1950) and Mary Ritter Beard (1876-1958), two early 20th century historians and educators who dedicated their professional lives to the study and advancement of Black history and women’s history respectively. In addition to their historical research and prolific publishing, Woodson and Beard devoted significant time and energy advocating an inclusive historical narrative in US schools and colleges. This work focuses on three of their primary goals: (1) challenging and correcting the accuracy of the historical record, (2) using history as a tool for mitigating racial and gender stereotypes, and (3) bringing women’s history and Black history to the public. The article concludes with a discussion of the relevance and usefulness for contemporary educators of strategies used by Beard and Woodson as they sought to correct the historical record and develop curriculum that would engage all students.

Abstract
Purpose
There is evidence that spirituality at the workplace has positive effects on work outcomes, and there are different models conceptualizing the construct. To date, there is no discussion highlighting how digitalization is affecting workplace spirituality and vice versa. The present review tries to close this gap by discussing the psychological dynamics in light of digitalization and spirituality in the context of work.
Design/methodology/approach
This is a conceptual discussion based on an extensive narrative review. The conceptual design is further tested with a real-life case study.
Findings
The result is a model that may guide future research, which consists of the four highly interdependent domains, namely psychology (with the dimensions of emotion, cognition and behavior), digitalization (with the dimensions of platforms, data and algorithms), spirituality (with the dimensions of meaning, self-transcendation and belonging), as well as the workplace (with the dimensions of work tasks, location, community and culture and values). The discussion includes implications for the future of work, suggestions for management decisions and potential future research directions.
Originality/value
To date, there are many discussions about digital transformation and a limited amount of them have invested in analyzing psychological dimensions. The application to spirituality and the workplace – especially when the two are combined – is almost wholly absent, which makes the present discussion both innovative and original.

Abstract
Purpose
This study aims to investigate whether firms purchase directors' and officers' liability (D&O) insurance when the country-level economic policy uncertainty (EPU) is high.
Design/methodology/approach
This study uses D&O insurance data from Chinese listed firms between 2003 and 2019 to conduct regression analyses to examine the association between D&O insurance and EPU.
Findings
The results show that government EPU, despite being an exogenous factor, increases the likelihood of firms' purchasing D&O insurance, and this effect is more pronounced when firms are exposed to great share price crash risk and high litigation risk, suggesting that firms intend to purchase D&O insurance possibly due to the accentuated stock price crash risk and litigation risk associated with EPU. In addition, the results indicate that the effect of EPU on the D&O insurance purchase decision is moderated by the provincial capital market development and internal control quality.
Practical implications
The study highlights the role of uncertain economic policies in shareholder approval of D&O insurance purchases.
Originality/value
The study enriches the literature on the determinants of D&O insurance purchases by documenting novel evidence that country-level EPU is a key institutional factor shaping firms' decisions to purchase D&O insurance.
