Mental health problems, particularly psychotic symptoms, are associated with polycystic ovary syndrome (PCOS) which may be linked to oestrogen signalling cascade following a period of sustained high oestrogen and dysregulation of cortisol. This case report aims to demonstrate a potential link and improvement following the use of Metformin.

The paper describes a case of a female with intellectual disability who presents with psychosis coinciding with PCOS and the aetiology of this association.

The case highlights some key points and complexities encountered in diagnosing and managing an individual with mental and physical health issues and an underlay of family dynamics and insecure attachment. A treatment approach involving recommendations from and joint working between professional groups including endocrinology, is highlighted.

There are very few studies to date that link PCOS to psychosis and only a single case report describes the use of Metformin. In a patient presenting with psychosis and PCOS, the consideration of an association with hormonal changes should be made, especially in patients with changing severity of psychosis and poor response to psychiatric medication. A “multimodal” intervention package needs to be considered for optimum benefit.

This chapter considers the mobilities of families subject to child protection involvement at the threshold of the birth of a new baby. The author presents data arising from an ethnographic study of child protection social work with unborn babies. This study aimed to draw near to social work practice within the Scottish context through mobile research methods and included non-participant observations of a range of child protection meetings with expectant families. Research interviews were sought with expectant mothers and fathers, social workers and the chair persons of Pre-birth Child Protection Case Conferences. Case conferences are formal administrative meetings designed to consider the risks to children, including unborn children. This chapter focusses on the experiences of expectant parents of navigating the child protection involvement with their as yet unborn infant. The strategies that parents adopted to steer a course through the multiple possibilities in relation to the future care of their infant are explored here. Three major strategies: resistance, defeatism and holding on are considered. These emerged as means by which expectant parents responded to social work involvement and which enabled their continued forwards motion towards an uncertain future.

The electric vehicle has been viewed as a technological solution to the dual plagues of dwindling fossil fuel supplies and pollutant emissions from gasoline powered vehicles. Futurists see a world where most personal transportation is electrically powered with energy supplied by tomorrow's power plants. In that future world, automobile power sources — representing millions of uncontrollable sources of pollution and energy waste — are consolidated into fewer, manageable, generators in fixed locations. With fixed and relatively few sources of pollution, resources can be better focused to provide clean, inexpensive energy for transportation. Many people share this vision of the future but few have been able to see how it can be brought into existence. Initial attempts have focused on legislation to stimulate the development of this market. As with any new technology, the electric vehicle field has developed its own terminology. For purposes of clarity throughout mis paper please bear in mind the following definitions.

As fake news and other disinformation are spread primarily online and erode trust in experts and institutions, they challenge the role of librarians as information gatekeepers. Experts have advocated for libraries to educate the public to resist misinformation, yet libraries cannot assume sole responsibility for information literacy work. In this chapter, the authors explore several successful information literacy programs in Ukraine, whose fake news problems made global headlines in 2014, when the Russian annexation of Crimea was accompanied by a flood of crude but effective disinformation. The authors look particularly at the Learn to Discern programs established by the international non-profit organization IREX to foster information literacy using techniques grounded in interdisciplinary expertise and carefully evaluated through pilot studies and follow-up evaluations. These programs train instructors through workshops and provide them with materials. In the first program, aimed at the general public, many of the instructors were librarians, and library facilities were heavily used to deliver the public training. In the second program, information literacy was integrated into the public school curriculum and thousands of teachers were trained to deliver expertly designed materials for particular grade levels and subjects. The authors also consider the special challenges posed by the COVID-19 pandemic, both as a source for new forms of misinformation and as a disruptor of training previously delivered in tightly packed libraries and classrooms. These Ukrainian programs demonstrate the potential for fighting fake news and other misinformation on a scale far beyond what could be accomplished by individual libraries acting alone.

The purpose of this paper is to investigate the factors that influence college students’ smartphone use for academic purposes by identifying the task-technology fit (TTF) of smartphones. A research model is proposed to explain how TTF of smartphones affects college students’ perceived academic performance and smartphone use.

Online surveys were administered to college students at a South Korean university that has offered online academic services for more than five years, and 1,923 valid responses were analyzed. The study used partial least squares path modeling to evaluate the measurement model, and the bootstrapping technique to test the significance of the hypotheses.

The findings highlight that the TTF of smartphones has a direct influence on students’ perceptions of performance impact and an indirect influence on smartphone use through a precursor of utilization, such as attitude toward smartphone use, social norms and facilitating conditions.

Despite a reasonably large sample, a single cross-sectional survey has a likelihood of selection bias in the sample.

This study applies the TTF model to smartphone use among college students and suggests an effective way to motivate them to use mobile technologies for their academic activities.

The present study develops an empirical model to assess the adoption of smartphones and its effect on college students’ academic performance. Above all, the study identifies a causal relationship among TTF, precursor of utilization, smartphone use and a perceived impact on academic performance based on the development and validation of the TTF constructs of smartphones.

General strikes emerged as part of an industrial repertoire of collective action that included singular strikes. While individual strikes continue, the United States has not experienced a general strike since 1946. What conditions facilitated the selection of this tactic by American labor? Why did the general strike disappear from labor's tactical repertoire after 1946? These questions are answered through a sequential analysis of the emergence of four American general strikes beginning in 1877 through 1946. Through a repertoire of collective action lens, I identify general conditions that increased the probability of general strike emergence. These general conditions, however, were also present in cities that did not have general strikes. To move beyond general conditions, I look at how they informed the local histories and historically contingent events that resulted in the “snowball effect” through which general strikes emerged from singular ones. I propose that American general strikes disappeared after 1946 due to changes in conditions that produced the industrial repertoire of collective action, foremost, changes in patterns of state repression through the passage of the Taft-Hartley Act.

This paper seeks to document an approach to reduce scrap losses using the root cause analysis technique in a lean manufacturing environment.

The study uses lean manufacturing root cause problem solving (RCPS) technique. The study starts with the collection phase, followed by the analysis phase and ends with the solution phase. Supporting data are presented using a Pareto chart to prioritise wastage in order to be more focused for improvement. The Toyota Production System's 5‐whys analysis is performed to analyse the cause of wastages, to formulate and implement corrective actions.

The application of the 5‐whys analysis in a manufacturing industry (XYZ Corporation) provides a fact‐based and structured approach to problem identification and correction that not only reduces, but also totally eliminates defects. Corrective action has permanently eliminated the top defect, which is the “last piece material scratch” and this results in zero scrap thereafter. In this study it was also proven that with sound understanding of manufacturing coupled with possible solutions using the 5‐whys analysis the authors were not only able to eliminate waste, but also to do it with zero‐cost.

The approach documented in the paper can be extended to other areas in the manufacturing industry to help improve overall equipment efficiency, breakdown, time loss, customer complaints, etc.
