Nutrient Intake and Physical Exercise as Modulators of Healthy Women
Cumulative evidence demonstrates that healthy nutrient intake and regular physical exercise are both powerful lifestyle strategies that modulate lifelong health through their ability to improve body composition, musculoskeletal health, sex steroid hormones, sleep quality, and physical and cognitive performance, as well as to prevent chronic diseases across the lifespan, especially in women. While the benefits of nutrition and physical exercise are commonly studied separately, the integration of nutrition and physical exercise has the potential to produce greater benefits in women than strategies focusing only on one or the other. Studying the specificities of women in response to interventions is of the utmost importance for providing optimal healthcare and aids the design of guidelines that are better suited for women. A better knowledge regarding nutrient intake and physical exercise and their interaction in women is therefore needed. This Special Issue entitled ânutrient intake and physical exercise as modulators of healthy womenâ will comprise manuscripts that highlight this integrational approach as a potential modulator of lifelong outcomes in women

COVID-19 Outbreak and Beyond
The COVID-19 pandemic drastically changed our lifestyle when, on 30 January 2020, the World Health Organization declared the coronavirus disease outbreak a public health emergency of international concern. Since then, many governments have introduced unprecedented containment measures, hoping to slow the spread of the virus. International research suggests that both the pandemic and the related protective measures, such as lockdown, curfews, and social distancing, are having a profound impact on the mental health of the population. Among the most commonly observed psychological effects, there are high levels of stress, anxiety, depression, and post-traumatic symptoms, along with boredom and frustration. At the same time, the behavioral response of the population is of paramount importance to successfully contain the outbreak, creating a vicious circle in which the psychological distress impacts the willingness to comply with the protective measures, which, in turn, if prolonged, could exacerbate the populationâs distress. This book includes: i) original studies on the worldwide psychological and behavioral impact of COVID-19 on targeted individuals (e.g., parents, social workers, patients affected by physical and mental disorders); ii) studies exploring the effect of COVID-19 using advanced statistical and methodological techniques (e.g., machine learning technologies); iii) research on practical applications that could help identify persons at risk, mitigate the negative effects of this situation, and offer insights to policymakers to manage the pandemic are also highly welcomed
Globalizing the Library
Globalizing the Library focuses on the globalization of information and the library in the period following the Second World War. Providing an examination of the ideas and aspirations surrounding information and the library, as well as the actual practices and actions of information professionals from the United States, Britain, and those working with organizations such as Unesco to develop library services, this book tells an important story about international history that also provides insight into the history of information, globalization, and cultural relations. Exploring efforts to help build library services and train a cohort of professional librarians around the globe, the book examines countries in Asia, Africa, and the Pacific during the period of the Cold War and decolonization. Using the ideas of âlibrary diplomacyâ and âlibrary imperialismâ to frame Anglo-American involvement in this work, Laugesen examines the impact library development work had on various countries. The book also considers what might have motivated nations in the global South to use foreign aid to help develop their library services and information infrastructure. Globalizing the Library prompts reflection on the way in which library services are developed and the way professional knowledge is transferred, while also illuminating the power structures that have shaped global information infrastructures. As a result, the book should be essential reading for academics and students engaged in the study of libraries, development, and information. It should also be of great interest to information professionals and information historians who are reflecting critically on the way information has been transferred, consumed, and shaped in the modern world
A systemic approach to the prevention and management of the causes of Hotel Environmental Sustainability Strategy Execution Failure (HESSEF)
Thesis (MEng)--Stellenbosch University, 2022.ENGLISH ABSTRACT: Our world is at risk due to unprecedented anthropogenic global warming leading to climate
change. From pre-industrial period (1850-1900) to 2006-2015, global mean surface (land and
ocean) temperature (GMST) and mean land surface air temperature (MSAT) respectively
increased by 0.87°C and 1.53°C, leading to increasing occurrence of severe natural disasters.
Hotels (184 thousand with 17 million hotel rooms in 2018) enable significant economic growth
and social progress within international tourism, the third largest industry in the world. In 2018,
this industry was worth USD 1.7 trillion, contributed 10.4 per cent to worldâs Gross Domestic
Product (GDP), cared for 1.4 billion tourists, and employed 319 million persons (one in ten
jobs).
Unfortunately, hotels also have negative environmental impacts and account for one to two
per cent of the five per cent global carbon dioxide emitted by the tourism industry. Hotels
hence contribute to the global warming and climate change.
There is a need to curb hotelsâ carbon dioxide emissions with appropriate strategies. However,
properly formulated strategies do not guarantee effective execution.
Strategy Execution (SE) is difficult to achieve and execution failure is possible. The execution
of Hotel Environmental Sustainability Strategies (HESS) is not an exception. A Hotel
Environmental Sustainability Strategy Execution (HESSE) paradigm shift and behaviour
change, with subsequent habits of effectiveness are hence required.
The aim of this study is to address the following research problem:
âThere is no model that can assist hotel practitioners (HP) and academics with a systemic
approach to the prevention and management of the causes of Hotel Environmental
Sustainability Strategy Execution Failure (HESSEF).â
The primary objective of the study is the development of the Seven Habits of Effective HESSE
(7HoE HESSE) model to address this problem. In support to the primary objective, a number
of secondary objectives are pursued. First, the world sustainability challenges and initiatives
are described. Second, the challenges of environmental sustainability within the context of
hotel management are understood and opportunities for improvement are identified. Third, the
challenges of HESSE are understood. Fourth, the escalation of HESSEF is analyzed and
possible HESSE paradigm shift and behaviour change for systemic HESSE enhancement are
studied. Fifth, the 7HoE HESSE model for HESSE systemic enhancement is conceptualized
and operationalized. Sixth, the model is verified. Seventh, the model is validated through face to-face structured interview of HP and feedback used for the model improvement.
The 7HoE HESSE model is described by HP as the way forward for sustainability as it provides
a good approach towards sustainability. HP highly appreciated the model describing it as a
great tool, highly suitable to the hospitality industry, interesting model, straight-forward, easy
to understand and well structured with appropriate monitoring HESSE processes. HP
expressed high willingness to experience the 7HoE HESSE model which properly summarizes
and contextualizes their reality. They are willing to experience the model as they believe it will
be very useful for favouring collaboration and commitment of all hotel stakeholders. They
expressed the views that the model could ensure successful execution of sustainability
projects in the hotel industry.AFRIKAANSE OPSOMMING: Die planeet word bedreig deur ongekende vlakke van aardverwarming wat lei tot
klimaatsverandering. Die gemiddelde Land en Oseaan temperature of the wel (GMST), sowel
as gemiddelde Land en Atmosfeer temperatuur of te wel (MSAT) het onderskeidlik met 0.87
grade celcuis en 1.53 grade celcuis toegeneem sedert die pre-industrieële periode (1850-
1900). Klimaatsverandering gee aanleiding tot natuur rampe.
Die hotel industrie het ân positiewe impak op ekonomies groei en sosiale ontwikkeling. Daar is
tans nie minder as 184 duisend hotelle and 17 miljoen hotel kamers. Toerisme was pre-Covid
die derde grootste industrie ter wĂȘreld en was in 2018 USD 1.7 triljoen werd. Die industrie was
verantwoordelik vir 10.4 persent van die wĂȘreld se Bruto Nasionale Produk, en het werk
verskaf aan 319 miljoen mense (een uit elke 10 werk geleenthede op aarde).
Hotelle het ongelukkig ook ân baie negatiewe impak op die omgewing en is verantwoordelik
vir tot 40 present van alle CO2 wat deur die toerisme bedryf geproduseer word. Dit is dus baie
belangrik vir hotelle om strategieë. te onwikkel wat hierdie potensiele nagatiewe impak kan
verlaag.
Strategie Uitvoering (SU) in die algemeen is moeilik en mislukking is baie moontlik. Die uitvoer
van ân Hotel Omgewings Volhoubaarheid Strategie (HOVS) is nie ân uitsondering nie. ân
Paradigma skuif en gedragsverandering is dus noodsaaklik om effeftiewe HOVS Uitvoering
(HOVSU) te verseker. Dit is dus verdermeer nodig om effektiewiteits gewoontes te kweek.
Die oogmerk van hierdie studie is om die volgende navorsingsprobleem aan te spreek:
âDaar bestaan tans geen model wat Hotel Operateurs (HO) en akademici kan bystaan om
deur middel van ân systematiese benadering die oorsake van Hotel Omgewings
Volhoubaarheid Strategie Uitvoerings Mislukking (HOVSUM) te verminder en te bestuur nie.â
Die primĂȘre doelwit van die studie is die ontwikkeling van ân gedragsveranderingsmodel wat
sal aanleiding gee tot die kweek van Sewe HOVSU gewoontes (7HoE HESSE). In
ondersteuning tot die primĂȘre doelwit is ân aantal sekondĂȘre doelwitte geformuleer. Eerstens
is die aard en omvang van die planeet se volhoubaarheidsuitdagins en inisiatiewe beskyf.
Tweendens is die omgewingsvolhoubaarheiduitdagings wat hotelle in die gesig staar beskryf.
Derderds is die problematiek aangaande HOVSU ondersoek en beskryf. Vierdens is die
verloop van HOVSUM en moontlikhede aangaande gedragsverandering en gewoonte
vorming beskryf. Die vyde sekondĂȘre doelwit was die formulering en operasionalisering van
die 7HoE HESSE model. In die sesde plek is die model geverifieer en in die sewende plek is
die model gevalideer tydens indiepte onderhoude met Hotel Operateurs en bestuurders sowel
as industrie kundiges.
Die terugvoer van beide operateurs en kundiges is besonder positief en die model word
beskryf as ân eenvoudige en prakties implementeerbare instrument om die problematiek wat
verband hou met die uitvoer van omgewingsvolhoubaarheid strategieë binne hotelle die hoof
te bied.Master
Motivations Associated with Food Choices and Eating Practices
This book is generally focused on food choice and which factors are associated with the decisions that define peopleâs eating behaviour. These factor are highly variable and include influences from the surrounding environment as well as the individual characteristics of each person. The book includes a number of chapters that address these issues from different points of view. Some explore the psychology of food choices or the cultural aspects and tradition, as well as the influence of surrounding contexts. Others focus on the role of lifestyle on eating practices and health motivations, but also the food marketing and the sensory aspects of food, as a way to incentive consumption. Finally, sustainability concerns and environmental impacts can also shape and help change peopleâs food choices.Within the chapters gathered on this book you will find key topics that apply to everyday food choices or that can help target food consumption goals towards better health, more sustainable food chains and happier life styles

Child Obesity and Nutrition Promotion Intervention
Childhood obesity continues to be a global problem, with several regions showing increasing rates and others having one in every three children overweight despite an apparent halt or downward trend. Children are exposed to nutritional, social, and obesogenic environmental risks from different settings, and this affects their lifelong health. There is a consensus that high-quality multifaceted smart and cost-effective interventions enable children to grow with a healthy set of habits that have lifelong benefits to their wellbeing. The literature has shown that dietary approaches play key roles in improving childrenâs health, not only on a nutritional level but also in diet quality and patterns. An association between the nutritional strategy and other lifestyle components promotes a more comprehensive approach and should be envisioned in intervention studies. This Special Issue entitled âChild Obesity and Nutrition Promotion Interventionâ combines original research manuscripts or reviews of the scientific literature concerning classic or innovative approaches to tackle this public health issue. It presents several nutritional interventions alongside lifestyle health factors, and outcome indicators of effectiveness and sustainability from traditional to ground-breaking methods to exploit both qualitative and quantitative approaches in tackling child obesity
A Phenomenological Study of the Experiences of School Leaders\u27 Preparation and Leadership of Inclusive and Special Education Programs
This transcendental phenomenological study describes how public school leaders experience learning and leading inclusive and special education programs. Two theories guided this study Knowlesâs adult learning theory and Mezirowâs transformative learning theory. The central research question for this study was how school leaders describe their professional experiences in leading inclusive and special education programming. The 10 participants in this study were school leaders endorsed in administration and supervision Kâ12. A criterion sampling was utilized for participant selection across three school districts in Central Virginia. The phenomenological approach was applied during data analysis. Horizontalization and coding were used to identify common themes and patterns. The data collected through interviews, participant journals, and a focus group revealed the following four major themes (and one sub-theme): Leadership Experiences Motivate Acquiring New Knowledge (with the sub-theme Leaders Identify Gaps in Their Knowledge), Developing Leadership Style Based on Self-Awareness, Leading through Experiential Learning, and Leading a Diverse School Culture Using an Inclusive Mindset. The data were analyzed to develop textural and structural descriptions to arrive at the essence of school leadersâ experiences. Results showed that school leaders lacked formal training in leading inclusive and special education, which impacted their proficiency to lead inclusive and special education programs. The study found that school leaders indicated a significant need to collaborate when making decisions for inclusive and special education programming. Implications from the study revealed school leadersâ need to receive adequate preparation before leading inclusive and special education to improve student outcomes
