Comparative assessment of the average failure rate of the basic elements of pneumatic systems has been presented. Structure oftechnical systems failures to ensure safety of technological processes involving protective gas has been described. Decisive influence of operating conditionsand parameters of protective gas industrial purity on safety of technological processes has been revealed.Regardless of the complexitylevel of the system, the occurrence of many kinds of failure is caused by negative impact of large-scale and subjective factors associated with the absence of objective monitoring of protective gasindustrial purity. Design, construction and operation of technical systems ensuring safety of technological processes involving protective gas is often based onprinciples typical for technological processes, not taking into account the specific features of operation of objects of protection.

This chapter examines the scaling and diffusion of green entrepreneurship between 1980 and the present. It explores how entrepreneurs and business leaders promoted the idea that business and sustainability were compatible. It then examines the rapid growth of organic foods, natural beauty, ecological architecture, and eco-tourism. Green firms sometimes grew to a large scale, such as the retailer Whole Foods Market in the United States. The chapter explores how greater mainstreaming of these businesses resulted in a new set of challenges arising from scaling. Organic food was now transported across large distances causing a negative impact on carbon emissions. More eco-tourism resulted in more air travel and bigger airports. In other industries scaling had a more positive impact. Towns were major polluters, so more ecological buildings had a positive impact.

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

The yips are a set of conditions associated with intermittent motor disturbances that affect precision movement, especially in sports. Specifically, skilled golfers suffer from the yips, although its clinical characteristics and pathophysiology have not been well-studied. We surveyed skilled golfers to characterize their yips-related symptoms, to explore potential confounding factors associated with the yips. Golfers’ demographic information, golfing-career-related history, musculoskeletal status and manifestations of the yips are surveyed. Among the 1576 questionnaires distributed, 1457 (92%) responses were received, of which 39% of golfers had experienced the yips. The median age and golfing careers were 48 and 28 years, respectively. Golfers who had experienced the yips were older and had longer golfing careers and more frequent musculoskeletal problems than those without experience of the yips. The multivariate logistic regression analysis revealed that a longer golfing career and musculoskeletal problems were independent factors associated with yips experience. More severe musculoskeletal problems were associated with higher odds of experiencing the yips. A positive association between the yips and musculoskeletal problems was also observed. The yips have similar characteristics to task-specific movement disorders, with a detrimental effect caused by excessive repetition of a routine task. These findings support the notion that the yips are a type of task-specific dystonia.

Aim: To explore Vietnamese–Australian children’s proficiency and use of Vietnamese and English and identify associated factors that are related to demographics, language practices, language ideologies, and language management. Methodology: Vietnamese–Australian parents ( n = 151) completed a questionnaire (in English or Vietnamese) regarding their child’s language proficiency and use, demographic details and a range of factors as conceptualized by Spolsky’s language policy theory: language practices; language ideologies; and language management. Data and analysis: Bivariate analyses (Pearson’s correlation and analysis of variance) and multiple regression models were conducted to explore associations between language proficiency and use and associated factors and identify the most significant factors. Findings/conclusions: Factors associated with children’s Vietnamese language proficiency (oral/written) included: demographic factors; language practices; language ideologies; and language management. In contrast, children’s English language proficiency (oral/written) was linked to demographic factors and language practices. Children’s Vietnamese language use was not significantly correlated with demographics but rather with language practices, language ideologies, and language management. Children’s home language use and proficiency did not have a negative impact upon their English proficiency. Originality: This study is the first to consider factors associated with Vietnamese–Australian children’s language proficiency and use. Significance/implications: Demographic factors, language practices, language ideologies, and language management were associated with children’s language proficiency and use. The results can be used by parents, educators, policy-makers, speech–language pathologists and other professionals to support Vietnamese–Australian and multilingual children around the world to develop and maintain their home and majority languages.

The purpose of the study was to highlight the factors associated with violence against women and girls and how they can benefit from therapy. The study was guided by the following objectives: to establish the factors associated with the occurrence of violence, determining the effectiveness of therapy in dealing with survivors of violence, exploring factors influencing or blocking effectiveness of therapy. A cross sectional research design was used in which questionnaires, an interviewing guide, focus group discussion and psychological assessment scale were used to collect study data. A sample of 75 women and girls was purposively selected from health facilities, counselling centres, chief camps, police station, NGOs and CBOs within Kibra Constituency. All respondents were females aged 18 years and above. The findings showed that all the respondents (100%) had been exposed to violence. The respondents who reported physical abuse were 30%, sexual abuse was reported by 10%, psychological and emotional abuse was reported by 16%, financial coercion was reported by 15%, neglect of children and duty by 13%, and verbal assault was reported by 16%.  Further, the results showed that the most common victims of violence are expectant mothers and children who are under the care of irresponsible persons. The most reported people to perpetrate violence were cited to be men. The responses given by the respondents as factors that trigger violence are: Previous assaults (61%), cultural expectations (61%), alcohol abuse and other drugs (49%), poor communication skills (49%), poor problem solving skills (49%), perpetrator outstretched demands on resources (49%), infidelity(37%), unemployment (37%), peer pressure (37%), frustration emanating from blocked goals (24%), childlessness (24%) and  personality traits (12%). Violence against women and girls impact negatively on their lives. The most common negative impact mentioned are depression by 75 respondents, children suffering cited by 65 respondents, family disintegration cited by 56 respondents, non-productivity, physical injury, and anxiety respectively cited  by 46 respondents. The survivors of violence have knowledge of where they can access help in order to cope with the consequences of violence. Of the 75 respondents, 75 of them said that counselling is very helpful. Perseverance is another coping mechanism mentioned by 75 respondents. Separation and keeping quite are strategies mentioned by 65 respondents. Going to hospital is another support and help available mentioned by 56 respondents. The respondents who opted for spiritual intervention were 47 while those who opted to start a business for sustainability were 38. Those who preferred sharing with significant others as a coping mechanism were 28. Last but not least, 18 women indicated that support groups are helpful in dealing with violence. The study recommended that women and girls should be empowered financially and policies put into place to curb violence. The government and other stakeholders should partner to support women and girls to overcome violence in the society.

The use of external labour such as temporary agency workers in the general workforce has increased in recent decades, but comparatively little is known about their impact within the aged care workforce. This article analyses quantitative data from a census of aged care facilities and a large-scale survey of their workforce regarding the use and impact of temporary agency workers on internal workers. It demonstrates that employing temporary agency workers helps address labour shortages generally and skill shortages in particular. However, it has a negative impact on the job satisfaction of internal personal care workers – a predictor of an increase in intention to leave. In contrast, there was little impact on internal nurse satisfaction. The use of temporary agency workers could therefore create a paradox: increasing personal care worker numbers in the short term, but negatively impacting on their retention in the long term. Given the need for an expanded and sustainable aged care workforce, this finding has important implications for organisations, policy and unions.

The challenges to fulfill the demand for a safe food supply are dramatically increasing. Mycotoxins produced by certain fungi cause great economic loss and negative impact on the sustainability of food supplies. Moreover, the occurrence of mycotoxins at high levels in foods poses a high health threat for the consumers. Biological detoxification has exhibited a high potential to detoxify foodstuffs on a cost-effective and large scale. Lactic acid bacteria showed a good potential as an alternative strategy for the elimination of mycotoxins. The current review describes the health and economic impacts associated with mycotoxin contamination in foodstuffs. Moreover, this review highlights the biological detoxification of common food mycotoxins by lactic acid bacteria.

Multiple empirical studies have revealed significant pandemic effects of COVID-19 on mental health in various populations. This study aimed to analyze the incidences of posttraumatic stress disorder (PTSD) and adjustment disorder (AjD) in national healthcare in 2018–2020 in one of the European countries—Lithuania—and estimate the effect of the COVID-19 pandemic on PTSD and AjD incidences in 2020. The national healthcare registry was used for estimations of diagnosis of PTSD, AjD, and major depressive disorder (MD). The study revealed that stress-related disorders PTSD and AjD are diagnosed rarely, resulting in a considerable gap between the expected prevalence and incidences of these diagnoses in healthcare in Lithuania. Moreover, a significant decline in mental disorders incidence in healthcare in 2020, in comparison to 2018 and 2019, was found, revealing that the COVID-19 pandemic had a negative impact on access to healthcare services and increased barriers for mental disorders treatment. The study indicates that major developments in building up knowledge about the effects of trauma and life stressors on mental health are needed in Lithuania and other countries to increase awareness about stress-related disorders and improve care for trauma survivors, in particular in the context of the pandemics or other large-scale disasters.
