This study examines reviewing tendencies in CHOICE, Journal of American History, and American Historical Review in the early 1990s in order to compare their strengths and weaknesses. Among the factors assessed were the number of titles reviewed by each, the degree of overlap for 1,017 different titles that were reviewed in these journals, subject coverage in the field of American history, and timeliness. The study found that JAH reviewed 50 percent more titles than the other two journals in 1991 and had the best coverage for most subject categories in American history. AHR reviewed the fewest books in most categories and contained the least number of unique titles. Although numbers of titles reviewed in each category differed, percentage of coverage was similar within most categories in all three journals. However, several categories revealed some divergence in coverage. Reviews in CHOICE preceded reviews of the same titles in JAH and AHR by 9.3 months and 10.9 months, respectively.

Drawing on the conservation of resources (COR) theory, this study aims to assess the moderating effect of the psychological contract (PC) type (relational, transactional and balanced) on the relationship between psychological contract breach (PCB) and organizational citizenship behaviours (OCBs).

The authors administered a survey to a sample of 159 nurses working in a large public hospital. To analyse the survey data, the authors used partial least squares with SmartPLS v.3.3, a variance-based structural equation modelling technique that combines principal component analysis, path analysis and regression analysis.

This study shows that nurses counteract the loss of resources following a PCB by investing more in stronger interpersonal relationships with co-workers and patients as a way to recuperate from resource loss and gain social resources. In addition, the moderating effect of the PC type reinforces the relationship between a PCB and OCB in a way that relational and balanced PC types support OCB-I positively but negatively OCB-O. Furthermore, the transactional PC does not reinforce negatively the link between PCB and OCB-I, and the negative interacting effect on the PCB and OCB-O link is only partially supported.

The study findings are grounded on a cross-sectional research design and a convenience sampling strategy.

The results highlight the relevance of human resources management practices centred on employee involvement and participatory supervision styles for ensuring OCB display at the workplace.

The results add new evidence to COR theory by highlighting the importance of social resources as a mitigator in the relationship between nurses’ PCB and OCB towards co-workers and patients (OCB-I). Hence, the OCB-I display will vary in function of the target and the moderating effect of PC type (relational, balanced or transactional).
