The NBA (National Basketball Association) is going through a transition process in its way of practice, planning, and comprehension of the game. With the exponential growth of the data that has been collected, detailed statistical analyses have been conducted for each part of the game. This has been overwhelming exploited in a way never seen before, especially when dealing with the three-point shot. In this paper, we are interested in characterizing NBA’s gameplay over time to identify trends and success factors. In particular, this study aims: (i) to identify which factors were crucial for teams’ regular season success in the past and understand the factors that are more relevant to succeed in the present day; and (ii) to group seasons and regular season winning teams into clusters of common characteristics and gameplay behavior. Historical events and trends help us to understand how teams were successful in past regular seasons, how they played, and how their style of play has changed. Leading to a better comprehension of the game. The game-related statistics of the NBA’s regular seasons, from 1979-80 to 2018-19, were analyzed using principal component analysis, cluster analysis, and LASSO regression. It is possible to identify three main Eras that we define as the Classic Era of the NBA (1980–1994), the Transitional Era of the NBA (1995–2013), and the Modern Era of the NBA (since 2013). As the results of this study make a historic analysis of the NBA, indicating the three eras of NBA regular seasons since the introduction of the three-point line, their playing styles, and their respective factors for success, this present research may be the base study that will help researchers better investigate the NBA, its past, present, and future.

With the intent of summing up the past research on ecodesign and making it more accessible, we gather findings from 106 existing review articles in this field. Five research questions on terminology, evolution, barriers and success factors, methods and tools, and synergies, guide the clustering of the resulting 608 statements extracted from the reference. The quantitative analysis reveals that the number of review articles has been increasing over time. Furthermore, most statements originate from Europe, are published in journals, and address barriers and success factors. For the qualitative analysis, the findings are grouped according to the research question they address. We find that several names for similar concepts exist, with ecodesign being the most popular one. It has evolved from “end-of-pipe” pollution prevention to a more systemic concept, and addresses the complete life cycle. Barriers and success factors extend beyond the product development team to management, customers, policymakers, and educators. The number of ecodesign methods and tools available to address them is large, and more reviewing, testing, validation, and categorization of the existing ones is necessary. Synergies between ecodesign and other research disciplines exist in theory, but require implementation and testing in practice.

ABSTRACT Multiwavelength monitoring of Mrk 335 with Swift between 2007 and 2019 are used to construct annual spectral energy distributions (SEDs) and track year-to-year changes. Non-contemporaneous archival data prior to 2007 are used to build a bright state SED. In this work, the changes are examined and quantified to build the foundation for future SED modelling. The yearly SEDs trace a downward trend on the average, with the X-ray portion varying significantly and acquiring further lower values in the past two years when compared to the optical/UV portion of SED. The bolometric Eddington ratios derived using optical/UV to X-ray SEDs and the calculated X-ray luminosities show a gradual decrease over the monitoring period. Changes in the parameters over time are examined. Principal component analysis suggests that the primary variability is in the X-ray properties of Mrk 335. When looking at the broader picture of Mrk 335 and its behaviour, the X-rays, accounting most of the variability in the 13-yr data, are possibly driven by physical processes related to the corona or absorption whereas the modest optical–UV variations suggest their origin within the accretion disc. These results are consistent with the previous interpretation of Mrk 335 using the timing analyses on the monitoring data and spectral modelling of deep observations.

We analyze the network of cross-border bank lending connections among countries from 1977 to 2018. The network includes core countries that lend money and peripheral countries that borrow money from core countries. In nowadays highly connected banking network, financial crisis that start from a country can spread to other countries very fast and cause global affects. We use principal component analysis (PCA) to find the influential lending (core) countries in this network over the years and clusters of borrowing (peripheral) countries related to these impactful core countries. We find three clusters of peripheral countries, with some constant and some changing members over time. This can be a sign of changes in the financial or political interactions among countries. The changes in the role of core countries and how these roles get affected by the important financial crisis in the past decades is investigated. Among 31 of core countries, 7 countries have a partially or constantly important role in the network including France, United Kingdom, United States, Japan, Germany, Chinese Taipei and Switzerland.

The traditional calendar had a great importance in the village’s life in the past because it indicated the optimal time for plowing and sowing, for the sheep to go to the pasture, the days favorable for collecting medical herbs, weddings, etc. But over time, it has undergone countless changes caused by various factors. First of all, it is about the role of science and its intense development since in the modern era, which had in the transformation of the traditional calendar into one of a more symbolic character. Secondly, it is about changing the political context: Bessarabia becomes the Moldovan Soviet Socialist Republic as part of U.S.S.R. and is subjected to ideological policies according to the instructions issued by Moscow, which aimed to Russify and denationalize the occupied peoples and form a new soviet consciousness. Last but not least, we must take into account the economic policy of U.S.S.R., which translated into life by applying a planned economy and, in general, a centralized planning in all spheres of life. Obviously, in such conditions, a large part of our ancestral traditions have not been passed down to us.

Abstract The article examines the conquest of the County of Tripoli by the Mamelukes in 1289, and the reaction of various Middle Eastern ethnoreligious groups to this event. Along with the Monophysite perspective (the Syriac chronicle of Bar Hebraeus’ Continuator and the work of the Coptic historian Mufaddal ibn Abi-l-Fadail), and the propagandist texts of Muslim Arabic panegyric poets, we will pay special attention to the historical memory of the Orthodox (Melkite) and Maronite communities of northern Lebanon. The contemporary of these events — the Orthodox author Suleiman al-Ashluhi, a native of one of the villages of the Akkar Plateau — laments the fall of Tripoli in his rhymed eulogy. It is noteworthy that this author belongs to the rural Melkite subculture, which — in spite of its conservative character — was capable of producing original literature. Suleiman al-Ashluhi’s work was forsaken by the following generations of Melkites; his poem was only preserved in Maronite manuscripts. Maronite historical memory is just as fragmented. The father of the Modern Era Maronite historiography — Gabriel ibn al-Qilaʿî († 1516) only had fragmentary information on the history of his people in the 13th century: local chronicles and the heroic epos that glorified the Maronite struggle against the Muslim lords that tried to conquer Mount Lebanon. Gabriel’s depiction of the past is not only biased and subject to aims of religious polemics, but also factually inaccurate. Nevertheless, the texts of Suleiman al-Ashluhi and Gabriel ibn al-Qilaʿî give us the opportunity to draw conclusions on the worldview, educational level, political orientation and peculiar traits of the historical memory of various Christian communities of Mount Lebanon.

The ambition of this book is to combine different bodies of scholarship that in the past have been interested in (1) providing social/structural analysis of financial elites, (2) measuring their influence, or (3) exploring their degree of persistence/circulation. The final goal of the volume is to investigate the adjustment of financial elites to institutional change, and to assess financial elites’ contribution to institutional change. To reach this goal, the nine chapters of the book introduced here look at financial elites’ role in different European societies and markets over time, and provide historical comparisons and country and cross-country analysis of their adaptation and contribution to the transformation of the national and international regulatory/cultural context in the wake of a crisis or in a longer term perspective.

For the past several decades, scholars have stressed that the genius of John Henry Newman remained underappreciated among his Roman Catholic contemporaries, and in order to find the true impact of his work, one must look to the century after his death. This book takes direct aim at that assumption. Examining a host of overlooked evidence from England and the European continent, Newman’s Early Legacy tracks letters, recorded conversations, and obscure and unpublished theological exchanges to show how Newman’s 1845 Essay on the Development of Christian Doctrine influenced a cadre of Catholic teachers, writers, and Church authorities in nineteenth-century Rome. The book explores how these individuals then employed Newman’s theory of development to argue for the definability of the new dogma of the Immaculate Conception of Mary during the years preceding the doctrine’s promulgation in 1854. Through numerous twists and turns, the narrative traces how the theory of development became a factor in determining the very language that the Roman Catholic Church would use in referring to doctrinal change over time. In this way, Newman’s Early Legacy uncovers a key dimension of Newman’s significance in modern religious history.

This book is about the ways in which humans have been bound affectively to the material world in and over time; how they have made, commissioned, and used objects to facilitate their emotional lives; how they felt about their things; and the ways certain things from the past continue to make people feel today. The temporal and geographical focus of ...


Anticorruption in History is the first major collection of case studies on how past societies and polities, in and beyond Europe, defined legitimate power in terms of fighting corruption and designed specific mechanisms to pursue that agenda. It is a timely book: corruption is widely seen today as a major problem, undermining trust in government, financial institutions, economic efficiency, the principle of equality before the law and human wellbeing in general. Corruption, in short, is a major hurdle on the “path to Denmark”—a feted blueprint for stable and successful statebuilding. The resonance of this view explains why efforts to promote anticorruption policies have proliferated in recent years. But while the subjects of corruption and anticorruption have captured the attention of politicians, scholars, NGOs and the global media, scant attention has been paid to the link between corruption and the change of anticorruption policies over time and place. Such a historical approach could help explain major moments of change in the past as well as reasons for the success and failure of specific anticorruption policies and their relation to a country’s image (of itself or as construed from outside) as being more or less corrupt. It is precisely this scholarly lacuna that the present volume intends to begin to fill. A wide range of historical contexts are addressed, ranging from the ancient to the modern period, with specific insights for policy makers offered throughout.

Background: Research is limited in evaluating the mechanisms responsible for infant growth in response to different protein-rich foods; Methods: Targeted and untargeted metabolomics analysis were conducted on serum samples collected from an infant controlled-feeding trial that participants consumed a meat- vs. dairy-based complementary diet from 5 to 12 months of age, and followed up at 24 months. Results: Isoleucine, valine, phenylalanine increased and threonine decreased over time among all participants; Although none of the individual essential amino acids had a significant impact on changes in growth Z scores from 5 to 12 months, principal component heavily weighted by BCAAs (leucine, isoleucine, valine) and phenylalanine had a positive association with changes in length-for-age Z score from 5 to 12 months. Concentrations of acylcarnitine-C4, acylcarnitine-C5 and acylcarnitine-C5:1 significantly increased over time with the dietary intervention, but none of the acylcarnitines were associated with infant growth Z scores. Quantitative trimethylamine N-oxide increased in the meat group from 5 to 12 months; Conclusions: Our findings suggest that increasing total protein intake by providing protein-rich complementary foods was associated with increased concentrations of certain essential amino acids and short-chain acyl-carnitines. The sources of protein-rich foods (e.g., meat vs. dairy) did not appear to differentially impact serum metabolites, and comprehensive mechanistic investigations are needed to identify other contributors or mediators of the diet-induced infant growth trajectories.
