<p class="emsd-body"><span lang="EN-GB">In order to make our lifestyles sustainable, changing our consumption patterns is fundamental. Hence, we need to better understand who the “consumers” are and to consider them as an active actor to directly engage for ensuring effective policies. In order to support a resource-light society, production and consumption need to be considered through an integrated system view; within this, consumers play an important role as co-acting subjects. Almost every activity in private life involves a form of consumption aimed at satisfying the subject’s needs and often regarded through an economic lens. Sustainable development is not about abolishing private consumption, but rather about making it environmentally, socially and individually sustainable in its design, organization and realization, also involving ideas of simplicity or renunciation. In this paper, we will assess the status quo of the German and European debates on Consumer Research Policies and discuss the idea to link sustainability research and consumer research – where a strategic relation is currently missing. Within that discussion, an evidence-based and obligatory consumer research strategy in Germany and Europe would represent a significant improvement. A system view perspective is necessary to take into consideration the impressive amount of diversity, and to elaborate realistic economic and consumer policies. Therefore, we propose nine steps for understanding the role of the consumer in implementing sustainable development from a scientific and political perspective. The limitations of this paper are thus a result of the very diverse and often unclear policies and agendas produced by governments. The implementation of the proposed innovative research agenda for a future-orientated and sustainability-based consumer research is not free from challenges. Still, the paper suggests the first steps towards this direction. After a critical discussion of the current EU and German consumer and sustainability policies, nine differentiated and substantial ways to integrate and ameliorate them are proposed.</span></p>

Full textAbstract:
In recent years, computer-based simulations have been used to enhance production processes, and sustainable industrial strategies are increasingly being considered in the manufacturing industry. In order to evaluate the performance of a gasification process, the Life Cycle Thinking (LCT) technique gathers relevant impact assessment tools to offer quantitative indications across different domains. Following the PRISMA guidelines, the present paper undertakes a scoping review of gasification processes’ environmental, economic, and social impacts to reveal how LCT approaches coping with sustainability. This report categorizes the examined studies on the gasification process (from 2017 to 2022) through the lens of LCT, discussing the challenges and opportunities. These studies have investigated a variety of biomass feedstock, assessment strategies and tools, geographical span, bioproducts, and databases. The results show that among LCT approaches, by far, the highest interest belonged to life cycle assessment (LCA), followed by life cycle cost (LCC). Only a few studies have addressed exergetic life cycle assessment (ELCA), life cycle energy assessment (LCEA), social impact assessment (SIA), consequential life cycle assessment (CLCA), and water footprint (WLCA). SimaPro® (PRé Consultants, Netherlands), GaBi® (sphere, USA), and OpenLCA (GreenDelta, Germany) demonstrated the greatest contribution. Uncertainty analysis (Monte Carlo approach and sensitivity analysis) was conducted in almost half of the investigations. Most importantly, the results confirm that it is challenging or impossible to compare the environmental impacts of the gasification process with other alternatives since the results may differ based on the methodology, criteria, or presumptions. While gasification performed well in mitigating negative environmental consequences, it is not always the greatest solution compared to other technologies.

"PSXII-20 Use of Statistical Process Control to Evaluate the Effect of Isoquinoline Alkaloids Supplementation on Productive Performance of Growing-Finishing Pigs."

Full textAbstract:
Abstract Statistical process control (SPC) is a statistical method that can be used to evaluate the production variation in swine operations, thus facilitating decision making. The objective of this study was to evaluate the effect of plant-derived isoquinoline alkaloids (IQs) supplementation on production performance of growing-finishing pigs by using SPC.The experiment was carried out in a commercial swine integration in Spain. Historical control (calibration) data was compiled from 2017 to June 2020. During this period, all animals received a standard commercial diet. During the treatment period, which started in July 2020 and lasted until February 2021, all pigs were fed the standard diet supplemented with 1 kg/t feed of a plant-based IQ product (Phytobiotics Futterzusatzstoffe GmbH, Eltville, Germany), from day 70 of life until slaughter. Data recorded during both, historical control and treatment periods included feed conversion ratio (FCR), average daily gain (ADG, g/d), average daily feed intake (ADFI, g/d), cost of medicines (Euro/pig), runts (%) and mortality rate (%). SPC tools were used to monitor the previously described performance parameters. CUSUM control charts were obtained for all parameters and for each nutritional and health cluster to show the evolution or the changes of each parameter. The results showed that pigs supplemented with IQs had a lower FCR, increased ADG and reduced cost in medications as compared to the control period (p ≤ 0.05; Table 1). SPC methods were successfully implemented to evaluate the effect of IQs supplementation on growth performance of grow-finish pigs. The results of the study indicated that IQs supplementation improved FCR and ADG, whereas the cost of medication was significantly reduced. Therefore, IQs supplementation in pigs from day 70 of life until slaughter could be a good strategy to improve the efficiency and profitability of the production system.

Full textAbstract:
Abstract Despite many years of research and great advances in the field, acute myeloid leukemia (AML) still remains one of the most challenging battle fields in the context of hematologic malignancies treatment. Although AML patients initially respond to conventional chemotherapy, a complete remission is rarely achieved and 5-year survival rates remain low especially in elderly patients. Hence, there is a pressing need for novel effective strategies for AML treatment to prevent relapse and treat minimal residual disease (MRD). The use of recombinant bispecific antibodies (bsAbs) for retargeting effector T lymphocytes towards cancer cells is recently emerging as a promising immunotherapeutic approach for tumor treatment. This class of small molecules is designed to bind simultaneously to a pre-defined tumor-associated antigen (TAA) on tumor cells and the activating CD3 complex on T cells. The cross-linkage of immune effector cell and tumor cell leads to a tumor-specific T cell activation and efficient target cell killing independently of the T cell receptor specificity. However, due to their low molecular mass, bsAbs have a short life span in vivo and consequently have to be continuously administrated to patients over prolonged time spans of several weeks to achieve clinical responses. As an alternative to continuous exogenous infusions of short-lived Abs we examined the use of engineered bone marrow-derived human mesenchymal stem cells (hMSCs) as cellular vehicles for the constant production and secretion of a fully humanized anti-CD33-anti-CD3 bsAb that targets the surface molecule CD33, which is widely overexpressed on AML blasts. Our studies demonstrate that gene-modified hMSCs are effective in releasing the bsAb at sufficient amounts to activate and redirect both human primary CD4+ and CD8+T cells from healthy donors against AML cells expressing varying levels of the CD33 antigen, leading to an efficient T cell-mediated tumor cell killing at low effector to target cell ratios and Ab concentrations. Most importantly, we could demonstrate that patient-derived T cells were able to suppress autologous AML blasts upon Ab-mediated cross-linkage over prolonged period of time without being affected by the presence of the modified hMSCs. Additional improvement of this system was achieved by the artificial expression of T cell co-stimulatory 4-1BB ligand (CD137L) on the hMSCs surface. The additional co-stimulatory signal provided by the engineered hMSCs resulted in an enhanced T cell proliferation, a higher pro-inflammatory cytokine release, and consequently in a more pronounced specific tumor cell killing already at earlier time-points. Taken together, our data could demonstrate that continuous in situ delivery of the anti-CD33-anti-CD3 bsAb by genetically modified hMSCs facilitates efficient activation of T cells for specific and efficient killing of AML blasts over prolonged period of time. Furthermore, as promising perspective of this approach for future in vivo application we are currently investigating on the development of biocompatible synthetic scaffolds as transplantable biomaterial-based production platforms for genetically engineered hMSCs as locally confined vehicle of immunotherapeutics. The implantation of these small engineered devices would ensure that the delivery of the anti-cancer agents can be controlled and stopped after tumor clearance by removing the scaffold at a desired time point. In this way, administration of ex vivo gene-modified hMSCs embedded in appropriate scaffolds would result in a continuous in situ production of recombinant Abs for effective and persistent levels of these therapeutic agents over time with low risk of side effects.

Full textAbstract:
Cultural Excavations by Nadezhda Venediktova were published in late autumn 2021, at the time most suitable for philosophical speculations. This way of thinking brings us close to a collapse that might equally turn out productive or catastrophic. Its anaemic academic manner stands out among full-blooded well-crafted literature of saturated and inspiring reality. Pandemic or not, we seek to know whether there is a need to distinguish between various cultures if at the end of the day people are still people. The author does not provide the answer but rather invites us to join a sophisticated mental game in fine textual decorations. And readers will walk away a little confused about simplicity of binary oppositions, and straightforwardness of the logic that a bored visitor so happily lays their hands on, eager and happy to get down to work. The book evolves around the topic of meeting thyself in different cultural surroundings. Sunlit essays bear the imprint of the bitter rationalism of the French enlightenment coupled with a weathered love of personal presence in the world. In her latest work, Nadezhda Venediktova ‘ambitiously comments on life’s creative abilities’. Vivid sketches entitled Passions for Europe may take place by a nameless lake in Zurich but remind readers of Michel Houellebecq’s concrete jungle, of Spengler’s mathematics. But nothing here speaks of The Decline of the West, under the author’s thoughtful gaze Europe comes to life fresh and real — a proverbial sphynx with its intriguing riddles. The author’s underworld meetings with the world literature alternate with colorful Italian landscapes. Vibrant images of friends are so true to life that remind of the immortality of soul. The soul of Europe is truly immortal and found across the continent — Italy, Britain, Austria, Germany, France, Greece, Switzerland, Spain — gave their name to the chapters but cannot be reduced to a dusty catalogue. Nadezhda Venediktova presents European countries through effortless florid metaphors. This what happens when Europe looks into the author’s soul, though it might look otherwise from an outside perspective.

Full textAbstract:
The aim of this research was to contribute to the growing body of academic literature regarding older women's stories of ageing. The initial impetus for the thesis came out of the disparity I observed between the way old women were often portrayed and the way older ageing was being lived by women I knew. Six women were recruited using an age range of 65 years and over and an association with a particular community organisation as recruitment guides. Two methods of data collection were used: diaries and semi-structured interviews. A qualitative narrative approach was taken to the data collection and analysis. The analysis revealed that the women viewed their ageing in a positive light. They constructed themselves as family orientated, as being and having friends and as active, independent participants within their own lives. Participants had clear ideas and expectations surrounding what they wanted from community participation and life in general. They spoke of the expectations of others and how these expectations sometimes lead to ageism and discrimination. Despite this it was apparent that being older had brought with it, for them, confidence, freedom, self-awareness and assertiveness. In short, these women required, actively sought, and usually accomplished, control of their own lives which involved places to go, people to see, things to do and most importantly the right to make their own choices.

Die Psychologie der Lebensspanne und die Soziologie des Lebensverlaufs betonen die Bedeutung von Kontexten für den Erwerb individueller Fähigkeiten und die Entwicklung im Leben. In Übereinstimmung mit diesen konzeptionellen Annahmen zeigen Studien, dass verschiedene Kontexte die Entwicklung individueller Bereiche beeinflussen. Jedoch ist wenig darüber bekannt, wie kontextuelle Faktoren in der zweiten Lebenshälfte Wohlbefinden formen und wie Wohlbefinden in diesen Lebensphasen von sich schnell verändernden Kontexten beeinflusst wird. In dieser Dissertation werden unter Anwendung des Ökosystemischen Ansatzes von Bronfenbrenner drei Kontexte unterschiedlicher Proximität untersucht, in die die Entwicklung des individuellen Wohlbefindens eingebettet ist. Als erster Kontext wird die vielfältige Ökologie des Lebens und Sterbens in den ehemaligen Regionen Ost- und Westdeutschland herangezogen, um herauszufinden wie dieses Makrosystem Wohlbefinden in den letzten Lebensjahren gestaltet. Als zweiter Kontext wird die Bedeutung des Exosystems von Gesundheitseinrichtungen in Landkreisen (z.B. Anzahl stationärer Pflegereinrichtungen) auf Wohlbefindensverläufe am Lebensende beleuchtet. Als dritten Kontext untersuchen wir, wie das Mikrosystem sozialer Ökologien und Situationen momentanes, affektives Wohlbefinden gestaltet, sowie Altersunterschiede in diesen Assoziationen. Gemeinsam zeigen die drei Studien dieser Dissertation, dass Ökologien auf regionaler, dienstleistender und sozialer Kontextebene Entwicklung von Wohlbefinden in der zweiten Lebenshälfte beeinflussen. Diese Arbeit zeigt, dass Kontexte sowohl kognitives als auch affektives Wohlbefinden und innerhalb des letzteren sowohl Valenz und Aktivierung beeinflussen, und untersucht länger- und kurzfristige Kontext-Wohlbefindens-Assoziationen in späteren Lebensphasen. Die Ergebnisse liefern erste Vorschläge für Interventionen und veränderbare regionale Faktoren für die Erhaltung oder Verbesserung von Wohlbefinden.Lifespan psychology and life course sociology have long acknowledged the role of context for individual functioning and development throughout life. Consistent with these conceptual notions, empirical studies show that various contextual factors influence development of individual-level outcomes. However, we know little about how contextual factors shape individual-level well-being and how well-being is influenced by fast changing contexts in the second half of life. Applying Bronfenbrenner’s model of human ecology as the overarching theoretical frame, this dissertation examines three sets of contexts that differ in the degree of proximity in which individual well-being and its development is embedded in. As a first context, the multifaceted ecology of living and dying in former regions of East and West Germany is used to investigate how the macrosystem shapes individual well-being in the last years of life. For a second context, the role of the exosystem of county-level health care features (e.g., number of inpatient care facilities) on late-life trajectories in well-being is examined. As a third context, we examine how the microsystem of social ecologies and situations influences momentary affective well-being and how these associations differ across age. Jointly, the three studies in this dissertation show that regional, service, and social ecologies profoundly shape development in well-being during the second half of life. To conclude, this dissertation shows that these contexts influence both cognitive and affective components of well-being, among the affective domain two facets (valence and arousal), and investigates long-term and short-term contextwell- being associations in later life phases. Results provide initial suggestions for interventions and malleable regional factors to maintain or improve well-being.

With an increasing proportion of older people in the Australian population and increasing health and longevity, paid work after the age of 65 years may become an option or a necessity in the future. The focus of this research is on Australian women of the baby boom generation, their working futures, and the work-retirement decision. This is explored both from the viewpoint of women and from a social policy perspective. The research draws on Considine�s model of public policy, futures studies, and Beck�s concept of risk society. The research comprises three studies. Using focus group research, Study 1 explored the views of Australian women of the baby boom generation on work after the age of 65 years. Study 2 aimed to explore current thinking on the research topic in Australia and overseas. Computer-mediated communication involving an Internet website and four scenarios for the year 2020 were used for this study. Study 3 consists of the analysis of quantitative data from the Healthy Retirement Project, focusing on attitudes towards retirement, retirement plans, and the preferred and expected age of retirement. The importance of choice and a work � life balance emerged throughout the research. Women in high-status occupations were found to be more likely to be open to the option of continuing paid work beyond age 65 than women in low-status jobs. However, the women were equally likely to embrace future volunteering. The research findings suggest that policies for an ageing female workforce should be based on the values of inclusiveness, fairness, self-determination, and social justice, and address issues of workplace flexibility, equality in the workplace, recognition for unpaid community and caring work, opportunities for life-long learning, complexity and inequities of the superannuation system, and planning for retirement. Further, providing a guaranteed minimum income for all Australians should be explored as a viable alternative to the current social security system.

After pervading Western Europe for more than twenty years, early retirement trends reversed in the mid-1990's when activation policies re-converted existing incentives to extend working life (EWL). This study investigates the institutional conditions explaining the cross-national variation of activation policies' outcomes in the Netherlands, Germany, and Italy between the mid-1990's and 2009. Revoking existing benefits for diffused and uncertain advantages, these policies faced harsh opposition from the coalitions (labour and capital organizations) interested in keeping the costs of early exit externalized for their members (older workers and their employers). In this study the central research question is: to what extent has the effectiveness of activation policies been affected by the organizational articulation of the externalization coalitions? The articulation of these coalitions is framed according to the affinities coupling protection, production and partnership institutions. From an actor-centered perspective, the EWL re-conversion is depicted as a sequential game. Under irresistible environmental pressure, the state first interact with social partners to retrench welfare incentives and then to encourage HRM strategies to retain older workers. The higher is the organizational articulation of labour and capital, the more interactions tend to be framed in social governance modes that, discouraging opportunistic actions, convey the EWL reconversion from the strategy of the state into the companies' HRM. In these cooperative modes social partners are thus expected to not hinder but to support the adoption of retrenchment and retaining policies. Being the articulation the highest in the Netherlands, lower in Germany and the lowest in Italy, the effectiveness of activation policies is expected to follow the same pattern. This hypothesis is tested using Event History Analysis on data drawn from the third wave of the SHARE in a two-stage research design estimating the effectiveness of retrenchment and retaining policies. The main findings show that social partners mediated the EWL re-conversion, promoting the effectiveness of activation in the Netherlands and hindering it among their members more in Italy than in Germany.

Das, Madhurima. "Development Of A Multi-Construct Framework For Assessing Work-Life Balance : Validation And Its Applicability In the Indian Context." Thesis, 2012. http://etd.iisc.ernet.in/handle/2005/2558.
Full textAbstract:
Introduction
Work-Life Balance is an area of interest to both researchers and organizations who strive to understand the various facets of work, life and work-life. For an individual and society today, balance is of paramount interest affected by the personality aspects, family aspects, support scenario, organizational culture and the existence of policies and their usage at the organizational level. The changing aspirations of individuals with time, across economies have made this a global issue . In India, the rapid urbanization in major cities and the manner in which individuals are embracing a 24*7 work environment, makes it crucial to understand Work-Life balance in a holistic and contextual manner. The efforts of the government and the organization along with the individual drive determines how the scales tilt in this strive for Work-Life balance.
Literature Review
The gamut of literature shows that Work-Life balance has been studied across countries and industries. Work-Life balance as an issue has been explored from both an organizational and individual perspective. The impact of demographic aspects like gender, age, education, marital status, family type, children and care taking responsibility have been delineated, along with personality aspects like leadership and motivation. Support has been delved into, both at family level and at organizational level; coupled with the impact of mentoring and networking. Researchers have worked towards understanding policies at the organizational level that help an individual attain Work-Life balance, along with individual philosophy and family culture. Work-Life balance attained by an individual is exhibited in their behavior towards their team and organization; the loyalty and commitment exhibited by them. It is evident in the satisfaction they experience and their positive attitude towards work. The positive impact on their families is also evident, in terms of the time they are able to spend with their family. While the literature looks at various aspects, the view is an isolated one and there is a need for a holistic and multi-construct understanding of Work-Life Balance.
Research Objectives and Methodology
The ensuing gaps from literature lead to the objectives of the study. The specific objectives of the study are:
1 To evolve and validate a multi-construct model of Work-Life Balance (WLB) in the Indian Context
2 To identify and relate organizational, individual and family factors affecting WLB.
3 To critically analyze the role of gender, organizational policies, self efficacy and organization type in understanding work-life issues
4. To suggest ways and means of mitigating WLB in the Indian context.
The various variables in the study were identified and the information framework was put in place. The preliminary study and the pilot study helped to finalise the questionnaire for the main study. The questionnaire comprised of two sections: Part B: My Perceptions of My Home and Work. Random sampling, coupled with the snowballing technique was the sampling technique adopted. The questionnaires were mostly administered in a face to face format; and in some cases, it was done over email as the respondents found that more convenient. The total sample of the study was 426 respondents 248 from public organizations, 118 from private organizations and 60 from entrepreneurial organizations. The data thus collected was subjected to statistical analyses.
Major Findings
First part of the analysis was carried out to establish the validity and the reliability of the questionnaire. This was done through factor analysis and by calculating the Cronbach's alpha. The factors analysis shows that the explanatory factors that emerge significant are aspects of culture, leadership and support; along with motivation towards family and work; including aspects of mentoring and networking. The mediating factors that emerge important revolve around aspects of Work-Life issues and impact of conflict; awareness and benefit of organizational policies; the perception of policy usage and individual thought. The output factors that emerge with high scores are the team and organizational engagement, impact of organizational support on work and family; the perception of work, the satisfaction with job and career and the citizenship behaviour exhibited.
To understand how different the groups, categorised by age, education, children, marital status, gender, family type, care taking responsibility and the organization type public, private and entrepreneurial, are on the factors; manova and t test was carried out. The groups emerge significantly different in terms of their understanding of organizational culture and involvement in networking. The way they view organizational support and the role of mentoring, how they view family support and responsibilities at home. How confident individuals feel about handling challenges and how satisfied they felt with their jobs and career, also differ between the groups. The next step in analysis involved understanding the experience of Work-Life balance and the individual impact of the explanatory, mediating and interaction factors on the various output factors of team and organizational engagement, the positive impact of policies on family, the perception of work, the job and career satisfaction experienced and the citizenship proactive behavior exhibited by the individual. Apriori models based on literature were developed and regression analysis was carried out. Many of the models emerged insignificant showing that Work as a phenomena cannot be understood through isolated factors. For this, a full model was developed with explanatory, mediating and interaction factors (explanatory*mediating) and their causal impact on the output factors was studied. It was seen that the model for team and organizational engagement emerged the strongest with the factors explaining 69% of the model. The results of the full model showed that different factors had major impacts on different output aspects. It was seen that organizational culture, self efficacy and family values and the motivation towards work, interacting with the existence and awareness of policies have the greatest impact on team and organizational engagement. The support seniors/boss, perceived stress and networking interacting with the usage effect of organizational policies have the greatest impact on organizational policy
positive impact on family. Organizational culture, perceived stress and networking interacting with the existence and awareness of organizational factors have the greatest impact on work perception. Job and career satisfaction is impacted the most by the motivation towards work, organizational policy existence, awareness and benefit and organization focus leadership interacting with the usage effect of policies. Finally, it is seen that networking, perceived stress and support from seniors and boss interacting with perceived stress have the greatest impact on citizenship proactive behavior. We thus see that Work Life balance is a multi-dimensional phenomena and its' comprehensive understanding is attained through multiple constructs.
Conclusion
This study provides a holistic understanding of Work Life Balance and is understood by looking at aspects of organizational culture, leadership, motivation, networking, mentoring, and support factors at both the organizational and the family level. The mediating role of organizational policies their existence, awareness and benefit and the usage effects on an individual; along with the role of self efficacy and family values and individuals' perception of stress becomes important. The experience of Work Life balance is understood through various behaviors exhibited team and organizational engagement shown by the individual, the positive impact of policies on family, the perception of work, the job and career satisfaction experienced and the citizenship proactive behavior exhibited by the individual. The comparison across groups and organization types public, private and entrepreneurial, show the importance of individual thought in mitigating Work Life issues. This study makes contributions at the theoretical level by developing and validating a multi-construct model for WLB. The study highlights the importance of organizational culture, organizational policies and the role of mentoring and networking that the organizations and managers need to delve into. This study entails scope in terms of extension of the model across organizations and cities in India and the development of a WLB measurement scale.

AbstractIdeally, life cycle sustainability assessment (LCSA) consists of life cycle assessment (LCA), life cycle costing (LCC) and social life cycle assessment (S-LCA) based on a joint technical model. For an integrated and consistent LCSA, however, this is not enough. Therefore, in this work, a coherent indicator selection based on the Sustainable Development Goals (SDGs) as well as an integration of the impact categories/indicators with the help of multi-criteria decision analysis is conducted. The chosen method PROMETHEE does not allow full compensation of the sustainability indicators, which reflects a possible view on sustainability. The SDG-based approach is compared with a classical approach where the weighting is based on the three sustainability dimensions. Both are tested on comparison case study of a 6 MW pressurized electrolyser located in three European countries, i.e. Spain, Germany and Austria, to illustrate the difference of industrial hydrogen production in industrialized countries with different structures of electricity markets.

Abstract The course of the disease is highly variable, and the spine does not always fuse completely as the disease may stay limited to the SI joints and the lower lumbar spine in some patients. Spinal structural damage seems to progress most rapidly when patients are 30–39 years of age. In women the spine fusion (ankylosis) tends to progress more slowly, and neck, anterior chest wall, and limb joint involvement may be the main or prominent manifestation. There is no cure yet for AS, but most patients can be very well managed with increasingly more effective medications and life-long programs of regular physical exercises. In general, most people do well and continue to live normal and productive lives, although some may have to modify their lifestyle or their work environment. There is a need for early disease detection, more effective anti-inflammatory treatment with biologics, as well management and prevention of comorbid conditions.

Increased automation, globalization, and longevity demand new thinking by employers and employees regarding productivity. Throughout the life span, fuller engagement in education, and paid and unpaid productive activities can generate a wealth of benefits, including better health and well-being, greater financial security, and a more vital society. We review challenges and opportunities to advance long, healthy, and productive lives. When possible, we review inequities by gender, race, ethnicity, and other social determinants of health to reveal heterogeneity within the growing US population and workforce. We conclude with implications for research, social policy, advocacy, education, and practice.

The demand for the quick transmission of data at any point and at any location motivates researchers from the industry and academics to work for the enhancement of ad hoc networks. With time, various forms of ad hoc networks are evolved. These are MANET, VANET, FANET, AANET, WSN, SPAN, etc. The initial objective of VANET is to provide safety applications by combining them with ITS. But later, the applications of VANET are extended to commercial, convenience, entertainment, and productive applications. Similarly, connections among multiple unmanned aerial vehicles (UAV) through wireless links, architectural simplicity, autonomous behaviour of UAV, etc. motivate the researchers to use FANET in various sectors like military, agriculture, and transportation for numerous applications. Search and rescue operations, forest fire detection and monitoring, crop management monitoring, area mapping, and road traffic monitoring are some of the applications of FANET. The authors mentioned some applications in the chapter using VANET, FANET, and the combination of VANET and FANET.

This chapter describes the work of Max Planck and Albert Einstein, who were the first to propose the new “quantum ideas” that Niels Bohr used in his atom. In 1900, Planck reluctantly proposed that light energy comes in discrete lumps called “quanta”, given by his equation, E = hν. Einstein, in his annus mirabilis of 1905 proposed that there are times when light cannot be described as an electromagnetic wave but rather as a stream of particles called photons. He used this particulate model of light to explain the photoelectric effect. We recall the tragedies and triumphs of Planck's life when, in Berlin and Göttingen, we visit his residences, honorary statues and plaques, the Archives of the Max Planck Society, and his simple grave amongst those of seven other Nobel Laureates. We briefly describe Einstein's early years, his education in Zurich, his marriage to Mileva Marić, the birth of their first son Hans and then go on to visit multiple sites in Ulm, Munich, Berlin, Bern, and Zurich where his life is celebrated with plaques, monuments, statues, elaborate church windows, museums and in the flat where he and Mileva lived during the most productive time of his life.

Social enterprises are expected to contribute to the well-being of society. One way this is done is through assisting individuals to become productive citizens. For those enterprises that work with individuals with disabilities, this is accomplished through education and assistance with various daily tasks. The disability population is increasing as the population ages and faces an increased potential for disability through disease and biological events as well as higher rates of diagnosis of developmental disability throughout the life span. When coupled with the increasing integration of individuals with disabilities into the community, there is a greater need for ways by which these individuals are included and supported. While technology is prevalent in today’s society, there is little training for those working with clients and little money to purchase the technology, leading to limited access. With few purchasers, little effort is expended to enhance the accessibility of existing technology and create more productive forms of technology. To decrease the costs to society, the role of social enterprises might research the necessary technology to further develop and facilitate the engagement of individuals with disabilities into society.

The Collaborative for Academic, Social, and Emotional Learning (CASEL) has identified 5 sets of social-emotional learning (SEL) skills (the CASEL 5): self-awareness; self-management; social awareness and empathy; relationship skills; and responsible, ethical decision-making. SEL is critical for students to be able to manage their own internal stressors, navigate their social environment successfully, and then access a comprehensive curriculum. It provides students with critical life skills such as problem-solving and perspective-taking that will span well beyond their schooling years, helping them to become productive members of society. In this chapter, the authors describe how to assess a school system’s infrastructure for SEL and discuss how to implement SEL at both Tier 1 and Tier 2 levels in an urban disadvantaged school district where many students have been impacted by trauma. A case study is presented.

This chapter discusses the transition from Kant's view of the self to that deeper but more problematic conception of the self which characterized the later idealism. The transition from Kant's philosophy to the later idealism was a reflection of the spirit which determined the course of contemporary social events. Three features marked the mental life in Germany during the decades with which the eighteenth century closed and the nineteenth century opened, say from 1770 to 1805. The first feature was the great development of actual productive power in scholarship, literature, imaginative work, and the accompanying increase in the popular respect for great individuals. The second was that deepening of sentiment, that enrichment of emotional life, which characterized first the storm and stress period, and later both the classical and the romantic literatures of Germany in those decades. The third feature was that relative indifference to mere political fortunes.

Full textAbstract:
Lobster fisheries represent some of the most iconic and valuable fisheries in the world. This chapter provides an overview of the commercial species of lobster in the families Palinuridae, Nephropidae, and Scyllaridae, commonly known as spiny, clawed, and slipper lobsters, respectively. Together, in 2015 these fisheries comprised about 14% of the economic value of crustacean fisheries globally. While the clawed lobster fisheries rank as the world’s most productive lobster fisheries, the spiny and slipper lobster fisheries are by far the most diverse. Notably, the clawed lobsters of the genera Homarus and Nephrops of the cool, temperate North Atlantic dominate world lobster production, whereas fisheries for the spiny lobster genera Panulirus, Palinurus, and Jasus and two slipper lobster genera, Thenus and Scyllarides, span much of the world’s tropical and warm temperate coastal zones. The review starts with a description of the distinguishing features of the biology and life history of the three families, including a geographic overview of their fisheries and how they are managed. Then discussed are the challenges confronting lobster fishing industries, fishery managers, and scientists in a changing ecosystem and global economy. The chapter closes by identifying directions for future research to address these challenges. Although space precludes an exhaustive review of all 27 commercial lobster fisheries recognized by the Food and Agriculture Organization (FAO), consistent and compelling themes emerge across the well-studied fisheries. Where long-term fisheries and environmental data time series have accumulated, it is evident that the geographic ranges of the productive segments of the fisheries are shifting poleward, forcing fishery scientists to reconsider long-held assumptions of stationarity common in stock assessment. These changes, in concert with the sometimes unpredictable forces of a global economy, have become a driving force for new innovations in the business and management of lobster fisheries.

Purpose: The chapter identifies the complexities of Covid-19’s impact on the economy. The empirical part presents and assesses initial reactions of inflation, industrial production, unemployment rate, Gross Domestic Product (GDP) growth rate, and shifts in the GDP expenditure structure. Design/methodology/approach: Acomplete Keynesian macroeconomic model is used to outline how the negative shock hit the economies. The model shows potential implications of the use of reactive economic policy measures. Based on the model, the empirical part provides comparative analyses of reactions of four economies of the European Monetary Union (EMU) – namely France, Germany, Italy and Spain – two non-EMU economies of Hungary and Poland, and two major large open economies: the USA and Japan. Findings: The Covid-19 pandemic has sent a universal, global shockwave with asymmetric outcomes in individual economies. Covid-19 hit all economies and struck both the demand side and – after ashort time lag – the supply side. Although interconnected, the economies have maintained notable structural differences and, therefore their autonomous reactions to negative demand and supply shocks were diverse. Practical implications: The complete macroeconomic Keynesian model allows for the conceptualization of the transmission of the Covid-19 shock on the economy’s supply and demand sides. The model is also a helpful tool in the analysis of the potential role of economic policy in reaction to the supply and demand shocks triggered by the pandemic. Originality and value: The empirical analyses unveil the eight economies’ differentiated reactions to similar counter-crisis policy measures. Their scale in all cases pushed the state back to the center of economic life. This structural shift requires attention and systematic theoretical and empirical studies.

Full textAbstract:
Sun comes into prominence as both a strong and clean energy source. Because of its being inexhaustible and creating an effect reducing import dependency, a noticeable progress has been made in solar-oriented technologies in recent years. In this regard, Germany as the pioneer in world, China whose installed solar capacity has overtaken Germany, and the USA and Japan which caught up Germany became benefited from solar energy significantly nowadays. Besides, the EU countries like Italy, England, France, Spain and Belgium are also raising their installed solar capacities.
Turkey has relatively high solar potential compared to the EU countries. However, it is not benefiting from solar energy sufficiently. Because its setup costs are still higher than other sources, solar production requires to be carried out R&D activities intensively. For these R&D activities there is a need for big budgets. Developed countries mentioned above could have been successful in allocating these budgets. Turkey as a developing country has difficulties in this respect.
The purpose of this paper is to reveal required policies and works to raise installed solar capacity and benefit more from solar energy in Turkey. In this context, primarily, policies imposed in leader countries in world with regards to benefit from solar energy will be examined. Thereafter, imposed policies and developments in Turkey until today in this respect will be mentioned. Consequently, suggestions will be made for Turkey in light of experiences of the countries that could have succeeded to benefit from solar energy by higher rates in primary sources.

Full textAbstract:
The EJ 200 engine powers the Eurofighter / Typhon combat aircraft and is being built by the four nations UK (RR), Germany (MTU), Italy (FIAT AVIO) and Spain (ITP). The engine is capable of 60 kN dry thrust and 90kN reheat thrust with a 15% built in growth potential. The specific thrust to weight ratio is ≈ 10 and the overall pressure ratio 26. MTU’s 33% work - share package contains the development of the three stage LP Compressor, the five stage HP Compressor and the Digital Engine Control Unit. This paper concentrates on the five stage axial HP Compressor. It describes the major design changes from the very first design verification engine (DVE) to a future all blisk version. It first provides a brief historical overview of the major design improvements which are then discussed in detail. The rotor concept is discussed with respect to life, weight, material and repair. The development of the casing to improve the tip clearance behaviour, the containment and the protection against titanium fire is outlined. The stator concept is described in connection with an intense cost reduction program. The HP Compressor has successfully completed testing and flight clearance has been approved for all standards. Thus far the HPC has accumulated more than 16500 hours total engine experience and over 1040 Eurofighter flights. The production engine manufacturing is in progress, with the first engine to be delivered in March 2001.

Full textAbstract:
There is increasing emphasis on improving the effectiveness of all physical assets, particularly major assets such as rotating equipment where the financial and business consequences of failure are significant. A number of approaches to asset (or maintenance) management have been proposed and attempted with varying degrees of success. Maintenance philosophies such as Total Productive Maintenance, Condition-Based Maintenance and Reliability Centered Maintenance are being heavily promoted by users and consultants alike. However, a consistent and comprehensive solution to business needs has not always resulted and implementation of these new techniques has often been only partially successful. This lack of success is often caused by the absence of a comprehensive approach to asset management that considers all aspects of the equipment life cycle. It is now beginning to be recognized that a risk-based approach offers a unique opportunity for providing an integrated perspective on the management of physical assets. Risk-based methods not only offer a powerful method for assisting in decision-making that can span from high level to lower level decisions but also provides specific tools that can be brought to bear on design, operational and maintenance needs. These methods fully support a life cycle view of assets that optimizes their effectiveness in the context of overall business goals and objectives. This paper describes the application of risk-based management and associated techniques to the life cycle of major rotating equipment in pipeline operation. A comprehensive framework consistent with best practices and international standards is established providing the basis for design, construction, operation and maintenance phases of the life cycle. Of key importance is the presentation of a decision-making process based on integrated risk that brings major value to operators of physical assets. Relevant risk-based techniques are described and evaluated for applicability to rotating equipment.

Full textAbstract:
Abstract With the ever-increasing pressure to drill wells efficiently at lower costs, the utilization of downhole sensors in the Bottom Hole Assembly (BHA) that reveal true downhole dynamics has become scarce. Surface sensors are notoriously inaccurate in translating readings to an accurate representation of downhole dynamics. The issue of 1 to 1 interpretation of surface to downhole dynamics is prevalent in all sensors and creates a paradigm of inefficient drilling practices and decision making. Intelligent mapping of downhole dynamics (IMoDD) is an analytical suite to address these inefficiencies and maximize the use of surface sensors, thus doing more with less. IMoDD features a new zeroing beyond the traditional workflows of zeroing the surface sensors related to weight and torque at the connection. A new method, Second-order Identifier of Maximum Stand-pipe-pressure: SIMS, is introduced. The method examines changes in stand-pipe pressure and identifies the point before bit-wellbore contact, using a set of conditions. The resulting calculations of weight and torque are verified with measured values of downhole weight and torque, for multiple stands of drilling in vertical, curve-lateral drilling. After the new zero, the deviation of torque-weight correlations is further examined to reveal the downhole weight changes confirmed also by the downhole sensor data. It is demonstrated that an intelligent mapping system that improves downhole characterizations would improve decision making to facilitate smoother energy transfer thus reducing Non-Productive Time (NPT) and increasing BHA life span.

Abstract In socialistic countries, customer satisfaction and the market conditions were not of high priority: Some selected parts of the market products were of satisfactory costs and quality to customers. Quality and costs of a product decide on its success in the world-wide market. The wishes and expectations of the customer for a high-quality and low-priced product continue to grow, however, with the desire for faster availability of this product. The customer determines also the delivery time and other competitive factors as the durability of the product. At present the trend goes towards shorter product life cycles, which in turn requires reduced time spent on the product development. With these complex market requirements and growing diversity of the products the engineer faces new challenges in his development tasks. It can be paraphrased as follows: In reduced lifecycles a quality-assured and advantageous product has to be developed despite increasing complexity of the design and demands for reduction of material used, manpower and monetary spending. For the solution of this complex problem the following suggestions are tested and implemented: • Structured design process for the development process, • Simultaneous work where ever possible during the development stages, • Employment of modern resources for the product development, • Use of information technology and • Implementation of rapid prototyping for models and in secondary manufacturing processes. An important research field at the Department of Mechanical Engineering Design at the Otto-von-Guericke-University Magdeburg is research and further development of productive procedures and tools for the realization of a computer integrated product development process. This process includes the effective application of technologies to produce the prototypes for presentation, producibility analysis and production. Of particular interest is the closed process chain (loop) from Solid Modeling via Rapid Prototyping and 3D-Digitizing where the entry point of this process chain depends on the needs of the application or particular interest of the innovating company. Information for faster and more competitive preparation, verification and Re-Engineering of existing and established products, which have to be adjusted to the world-market needs, will be made available. The results of this applied research offer opportunities to display new developed products for the lagging industries in the former East Germany, and furthermore arranging for necessary venture capital to produce the product, to gain information about possible suppliers and manufacturing opportunities in order to minimize the investors’ risks of an enterprise.
