Smart Logistics in Industry 5.0
Given the importance of human centricity, resilience, and sustainability, the emerging concept of Industry 5.0 has pushed forward the research frontier of the technology-focused Industry 4.0 to a smart and harmonious socio-economic transition driven by both humans and technologies, where the role of the human in the technological transformation is predominantly focused on. The core elements of Industry 5.0 show that following the technology-centric transition of Industry 4.0, the societal, environmental, and human perspectives require more attention, which will yield significant impacts on logistics operations and management. For instance, the personalization of demands implies a personalized delivery system. Incorporating customers into the design requires highly intelligent CPS and system integration. Human–machine interaction triggers the interaction of various topics such as safety, human behavior, etc. Thus, there exist various challenges and approaches to addressing smart logistics issues in Industry 5.0.

Plug-in Electric Vehicles in Germany
The adoption of plug-in electric vehicles in Germany is actively supported by the German Federal Government. Under its National Plattform for Electric Mobility, Chancellor Angela Merkel set an initial goal in 2010 to deploy one million electric vehicles on German roads by 2020. Initially, the government did not provide subsidies to promote sales of plug-in electric vehicles, however, by the end of 2014 it was recognized that the country was well behind the set sales targets. A purchase bonus scheme was approved in 2016, but premium cars were not eligible to the incentive. In order to meet the climate targets for the transport sector, in 2016 the government set the goal to have from 7 to 10 million plug-in electric cars on the road by 2030, and 1 million charging points deployed by 2030. In June 2020, and as a result of the economic impact of the COVID-19 pandemic, the government approved a recovery plan which included €8 billion to promote electric vehicle adoption and deployment of charging infrastructure. The purchase bonus for all-electric cars was raised temporarily from €6,000 to €9,000 for cars costing less than €40,000. There are lower bonuses for the purchase of plug-in hybrids, used cars and for leasing. The additional bonus will be available until the end of 2025. The initial one million goal was achieved in July 2021. The stock of plug-in electric vehicles in Germany is the largest in Europe, and (As of July 2021), there were 1 million plug-in electric vehicles on the road, including buses and commercial vehicles. The German fleet in use consists of 54% all-electric vehicles and 46% plug-in hybrids. (As of December 2019), Germany had a stock of 21,890 light-duty electric commercial vehicles, the second largest in Europe after France. (As of March 2020), the country had 27,730 public charging stations. The plug-in electric car segment market share was 1.58% in 2017 and 1.9% in 2018. The segment market share rose to 3.10% in 2019, and despite the global strong decline in car sales brought by the COVID-19 pandemic, the uptake rate achieved a record 13.6% in 2020. (As of January 2021), the stock of German plug-in electric cars on the road totaled 588,944 units, representing 1.2% of all registered passenger cars, up from 0.5% the previous year. In 2019, Germany surpassed Norway as Europe's top selling country market in terms of annual sales, and with a record volume of 394,632 plug-in passenger cars registered in 2020, up 263% from 2019, Germany listed for a second year running as the best selling European plug-in market. Both years, the German market led both the fully electric and plug-in hybrid segments. The only country that outsold Germany in 2020 was China.

Karhunen–Loève Theorem
In the theory of stochastic processes, the Karhunen–Loève theorem (named after Kari Karhunen and Michel Loève), also known as the Kosambi–Karhunen–Loève theorem is a representation of a stochastic process as an infinite linear combination of orthogonal functions, analogous to a Fourier series representation of a function on a bounded interval. The transformation is also known as Hotelling transform and eigenvector transform, and is closely related to principal component analysis (PCA) technique widely used in image processing and in data analysis in many fields. Stochastic processes given by infinite series of this form were first considered by Damodar Dharmananda Kosambi. There exist many such expansions of a stochastic process: if the process is indexed over [a, b], any orthonormal basis of L2([a, b]) yields an expansion thereof in that form. The importance of the Karhunen–Loève theorem is that it yields the best such basis in the sense that it minimizes the total mean squared error.

Post-Materialism
In sociology, post-materialism is the transformation of individual values from materialist, physical, and economic to new individual values of autonomy and self-expression. The term was popularised by political scientist Ronald Inglehart in his 1977 book The Silent Revolution, in which he discovered that the formative affluence experienced by the post-war generations was leading some of them to take their material security for granted and instead place greater importance on non-material goals such as self-expression, autonomy, freedom of speech, gender equality and environmentalism. Inglehart argued that with increasing prosperity, such post-material values would gradually increase in the publics of advanced industrial societies through the process of intergenerational replacement. Post-materialism is a tool in developing an understanding of modern culture. It can be considered in reference of three distinct concepts of materialism. The first kind of materialism, and the one in reference to which the word post-materialism is used most often, refers to materialism as a value-system relating to the desire for fulfillment of material needs (such as security, sustenance and shelter) and an emphasis on material luxuries in a consumerist society. A second referent is the materialist conception of history held by many socialists, most notably Marx and Engels, as well as their philosophic concept of dialectical materialism. The third definition of materialism concerns the philosophical argument that matter is the only existing reality. The first concept is sociological, the second is both philosophical and sociological, and the third is philosophical. Depending on which of the three above notions of materialism are being discussed, post-materialism can be an ontological postmaterialism, an existentialistic postmaterialism, an ethical postmaterialism, or a political-sociological postmaterialism, which is also the best known.

Hereditary Hemochromatosis
The environment and the human genome are closely entangled and many genetic variations that occur in human populations are the result of adaptive selection to ancestral environmental (mainly dietary) conditions. However, the selected mutations may become maladaptive when environmental conditions change, thus becoming candidates for diseases. Hereditary hemochromatosis (HH) is a potentially lethal disease leading to iron accumulation mostly due to mutations in the HFE gene. Indeed, homozygosity for the C282Y HFE mutation is associated with the primary iron overload phenotype. However, both penetrance of the C282Y variant and the clinical manifestation of the disease are extremely variable, suggesting that other genetic, epigenetic and environmental factors play a role in the development of HH, as well as, and in its progression to end-stage liver diseases. Alcohol consumption and dietary habits may impact on the phenotypic expression of HFE-related hemochromatosis. Indeed, dietary components and bioactive molecules can affect iron status both directly by modulating its absorption during digestion and indirectly by the epigenetic modification of genes involved in its uptake, storage and recycling. Thus, the premise of this review is to discuss how environmental pressures led to the selection of HFE mutations and whether nutritional and lifestyle interventions may exert beneficial effects on HH outcomes and comorbidities.

Aesthetic Education in Chinese Schools
Since the promulgation of the first school education regulations in the early 20th century, Chinese school aesthetic education has gone through its first century of history. Six stages of development have been formed in this century of vicissitudes, namely, the budding period, the starting period, the salvation movement period, the tortuous development period, the reconstruction period, and the modernization period of the new era. Aesthetic education in Chinese schools places a prominent place on “establishing, cultivating and clarifying morality”, emphasizes the role of “beauty” in “goodness”, and follows the aesthetic guideline of “unity of beauty and goodness”. Art education and its practical activities are the main content of school aesthetic education. The formation mechanism, laws, and characteristics of the sustainable development of school aesthetic education in China are summarized from the perspective of the century-old school aesthetic education policy, which is of theoretical guidance for the study of the future development of school aesthetic education in China.

Pointing-Out Instruction
The pointing-out instruction (ngo sprod) is the direct introduction to the nature of mind in the Tibetan Buddhist lineages of Mahāmudrā and Dzogchen. In these traditions, a "root guru" gives the "pointing-out instruction" in such a way that the disciple successfully recognizes the nature of mind. The tradition of conferring such instructions outside the context of formal empowerment (Sanskrit: abhiṣeka) is unique to the Kagyu and Nyingma lineages. Whether or not such instructions are valid without the formal empowerment has historically been a point of contention with the more conservative Gelug and Sakya lineages. The pointing-out instruction is often equated with the fourth formal vajrayana empowerment.

Jackson Family
The Jackson family is an important and influential American family of singers that has garnered prominence in the music industry, originated from Gary, Indiana. Performing as members of The Jackson 5 and as solo artists, the children of Joseph Walter and Katherine Esther Jackson were very successful in the field of popular music from the late 1960s onwards. As a group, the eldest sons Jackie, Tito, Jermaine, Marlon, Michael, and later with the inclusion of Randy. The members who managed to be solo icons in music are Michael Jackson and Janet Jackson. The Jackson 5 became known as the "First Family of Soul" (a title first held by the Five Stairsteps). The continued success of Michael and Janet's careers as solo artists led the Jacksons to become known as the "Royal Family of Pop". All nine of the Jackson siblings have gold records to their credits with La Toya holding the distinction of being the first Jackson sister to attain one (awarded by France's SNEP for "Reggae Night", a song she co-wrote for Jimmy Cliff), and now to Janet Jackson for being the first black woman to receive the Billboard Icon Award. The Jackson family has been the subject of controversy linked to the Jordan Chandler Case. But the most controversial facts of Jackson's private life are accusations made by his sons against family patriarch Joseph Jackson claiming that he was harassed by his father as a child. Despite these circumstances and other problems, the Jacksons continued to be one of the most influential families in the United States and in recent years some family members have been honored for their work; in 1997 The Jackson 5 was inducted to the Rock and Roll Hall of Fame. Michael would follow the group to the hall in 2001. The Jacksons, Michael and Janet all received stars on the Hollywood Walk of Fame in 1980, 1984 and 1990 respectively. Joseph was recognized as "the best musical businessman of all time" by the city of Cleveland in 2002. In 2009 a new series from A&E entitled The Jacksons: A Family Dynasty premiered documenting the Jackson brothers dealing with the sudden loss of Michael and preparing for a Jackson 5 Reunion tour. The most popular member of the Jackson family was Michael Jackson, known as the King of Pop and died in June 2009, due to a cardiac arrest.
