Abstract
Few will complain that 1974 has not been an eventful year; in a number of significant respects, it has made history. Local Government and National Health Services reorganizations are such events. This is indeed the day of the extra‐large authority, massive monoliths for central administration, metropolitan conurbations for regional control, district councils corresponding to the large authorities of other days; and in a sense, it is not local government any more. As in other fields, the “big batallions” acquire greater collective power than the total sum of the smaller units, can wield it more effectively, even ruthlessly, but rarely appearing to take into account the masses of little people, the quiet people, who cannot make themselves heard. As expected, new names of authorities are replacing the old; new titles for departments and officers, ambitious and high‐sounding; a little grandiose for the tongues of ordinary folk. Another history‐making event of 1974, in the nature of a departmental transfer but highly significant for the course of future events as far as work in the field is concerned, was handing over of the personal health services—health of expectant mothers, babies, children, domiciliary midwifery, the school health services and their mainly medical and nursing personnel—from local health authorities to the newly created area health authorities. The public health departments over fifty years and more had created them, built them up into the highly efficient services they are. If anything can be learned from the past, new authorities are always more expensive than those they replace; they spend freely and are lavish with their accommodation and furnishings. In their first few months of existence, the new bodies have proved they are no exception. News of their meetings and activities in many areas is now scanty; even local newspapers which usually thrive on Council news—or quarrels—seem to have been caught on the wrong foot, especially in the small towns now merged into larger units. The public are relatively uninformed, but this doubtless will soon be rectified.

Abstract
This paper assesses the strength of the evidence on the impact of the physical environment on mental health and well‐being. Using a systematic review methodology, quantitative and qualitative evaluative studies of the effect of the physical environment on child and adult mental health published in English between January 1990 and September 2005 were sought from citation databases. The physical environment was defined in terms of built or natural elements of residential or neighbourhood environments; mental health was defined in terms of psychological symptoms and diagnoses. A total of 99 papers were identified. The strength of the evidence varied and was strongest for the effects of urban birth (on risk of schizophrenia), rural residence (on risk of suicide for males), neighbourhood violence, housing and neighbourhood regeneration, and neighbourhood disorder. The strength of the evidence for an effect of poor housing on mental health was weaker. There was a lack of robust research, and of longitudinal research in many areas, and some aspects of the environment have been very little studied to date. The lack of evidence of environmental effects in some domains does not necessarily mean that there are no effects: rather, that they have not yet been studied or studied meaningfully.

Abstract
Purpose
This review aims to provide synoptic documentation on acclaimed anecdotal plant-based remedies used by Latin America and the Caribbean (LAC) communities to manage COVID-19. The theoretical approaches that form the basis for using the anecdotally claimed phytotherapies were reviewed against current scientific evidence.
Design/methodology/approach
In this paper plant-based remedies for managing COVID-19 were searched on social and print media to identify testimonies of people from different communities in LAC countries. Information was extracted, evaluated and reviewed against current scientific evidence based on a literature search from databases such as Journal Storage (JSTOR), Excerpta Medica Database (EMBASE), SpringerLink, Scopus, ScienceDirect, PubMed, Google Scholar and Medline to explore the scientific basis for anecdotal claims.
Findings
A total of 23 medicinal plants belonging to 15 families were identified as phytotherapies used in managing COVID-19 in LAC communities.
Originality/value
The plant-based remedies contained valuable phytochemicals scientifically reported for their anti-inflammatory, antiviral, antioxidant and anticancer effects. Anecdotal information helps researchers investigate disease patterns, management and new drug discoveries. The identified acclaimed plant-based remedies are potential candidates for pharmacological evaluations for possible drug discovery for future pandemics.

Abstract
Purpose
Because of the shortage of energy, the development of green and reliable energy is particularly important. As a green and clean energy, wind power is widely used. As the core component of wind power generation, it is particularly important to choose generators with high reliability. Switched reluctance machine is widely used as generators because of its strong fault tolerance and high reliability. Therefore, this paper aims to propose a power converter and its control strategy to improve the efficiency of switched reluctance generators.
Design/methodology/approach
In this paper, a full-bridge power converter (FBPC) instead of the asymmetric half-bridge power converter (AHBPC) is adopted to drive the switched reluctance generator (SRG) system. Compare the FBPC with the AHBPC, the FBPC has several advantages including low cost and modularization, and operation process of SRG winding current direction is variable.
Findings
The results show that the SRG system can keep smooth operation by the FBPC with relatively high efficiency.
Originality/value
The FBPC is suitable to drive the SRG system. Meanwhile, this paper introduces two excitation modes of the FBPC as three-phase three-beat mode and six-phase six-beat mode. When the six-phase six-beat control strategy is adopted, the dead band time of the converter can be avoided. At the same time, the SRG has higher efficiency.

Abstract
Purpose
This paper aims to propose an effective method to verify poles polarities of switched reluctance motors (SRMs). Different from the ways of detection poles polarities by permanent magnet in SRMs, the difference of self-inductance between different winding connections is used to verify the pole polarity.
Design/methodology/approach
First, the winding connections with the forward and reverse series are proposed. The magnetic circuit models are established to analyze the flux linkage of different winding connections. Then, according to the difference of inductance characteristics, including the self-inductance and the mutual inductance affected by the adjacent poles, it is theoretically feasible to verify the polarity of each pole. Finally, the proposed method is verified by the simulation and experiment on a six-phase SRM.
Findings
First, compared to the reverse series, the forward series can produce larger self-inductance when one phase is excited at the same current excitation, which can be used to verify the poles polarities of one phase with different winding connection. Second, the mutual inductance can be used to distinguish the winding connections. Third, the difference of the maximum self-inductance of the winding, which is composed of two adjacent windings, can be used to verify the polarities of the adjacent poles.
Originality/value
This paper proposes an effective method to verify poles polarities of SRMs.

Abstract
Children must rely on adults to provide the economic and human resources essential to assure their well-being and development, because it is the adults in their families, communities, and the halls of government who determine the nature and magnitude of resources that reach children (e.g., Bronfenbrenner, 1979; Haveman & Wolfe, 1994). In view of this dependence of children on adults, this chapter has three main goals. The first is to portray the extent to which children in the United States and other selected rich countries experience limited access to economic resources, compared to the adults in each country. The second is to focus on key family circumstances of children which reflect human resources available in the home and which influence the level of economic resources that parents have available to provide for their children. The third is to draw attention to differences among the race, ethnic, and immigrant groups that are leading the demographic transformation of rich countries around the world.

Abstract
Purpose
Labor process theory explains that employers prefer technology and systems over employees for efficiency gains. However, the mechanisms explaining the influence of technology and systems on different work-related employee outcomes are still a question mark. The purpose of this study is to test a mediation mechanism explaining how workforce analytics influence the work fulfillment experience of employees through work volition.
Design/methodology/approach
This study collected dyadic data from 55 HR managers and 350 employees serving in 55 different subsidiaries of Multinational Corporations in Pakistan.
Findings
The statistical results demonstrate that workforce analytics negatively affect fulfillment at work. However, work volition may reduce the negative relationship between workforce analytics and fulfillment at work. This study also found a significant but negative relationship between work volition and fulfillment at work.
Originality/value
This study found that integrating the use of workforce analytics with the work volition of employees is critical for positive employee outcomes.
