Motor development research has had a rich history over the 20th century with a wide array of scientists contributing to a broad and deep body of literature. Just like the process of development, progress within the field has been non-linear, with rapid periods of growth occurring after the publication of key research articles that changed how we conceptualized and explored motor development. These publications provided new ways to consider developmental issues and, as a result, ignited change in our theoretical and empirical approaches within the field of motor development and the broader field of developmental psychology. In this paper, we outline and discuss six pioneering studies that we consider significant in their impact and in the field’s evolution, in order of publication: Halverson, 1931; Wild, 1938; Gibson & Walk, 1960; Connolly, Brown, & Bassett, 1968; Thelen & Fisher, 1982; Thelen & Ulrich, 1991. We have limited this review to empirical papers only. Together, they offer insight into what motor development research is, where it came from, why it matters, and what it has achieved.

In 1989, Clark and Whitall asked the question, “What is motor development?” They were referring to the study of motor development as an academic research enterprise and answered their question primarily by describing four relatively distinct time periods characterized by changes in focus, theories or concepts, and methodology. Their last period was named the process-oriented period (1970–1989). In hindsight, it seems clear that their last period could be divided into two separate historical time periods: the information-processing period (1970–1982) and the dynamical systems period (1982–2000). In the present paper, we briefly revisit the first three periods defined by Clark and Whitall, and expand and elaborate on the two periods from 1970 to the turn of the century. Each period is delineated by key papers and the major changes in focus, theories or concepts, and methodology. Major findings about motor development are also described from some papers as a means of showing the progression of knowledge.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.


Organizational contradictions and process studies offer interwoven and complementary insights. Studies of dialectics, paradox, and dualities depict organizational contradictions that are oppositional as well as interrelated such that they persistently morph and shift over time. Studies of process often examine how contradictions fuel emergent, dynamic systems and stimulate novelty, adaptation, and transformation. Drawing from rich conversations at the Eighth International Symposium on Process Organization Studies, the contributors to this volume unpack these relationships in more depth. The chapters explore three main, connected themes through both conceptual and empirical studies, including (1) offering insight into how process theorizing advances understandings of organizational contradictions; (2) shedding light on how dialectics, paradoxes, and dualities fuel organizational processes that affect persistence and transformation; and (3) exploring the convergence and divergence of dialectics, paradox, and dualities lenses. Taken together, this book offers key insights in order to inform persistent, contradictory dynamics in organizations and organizational studies.

Rural development research integrates numerous theoretical and empirical studies and has evolved over the past few decades. However, few systematic literature reviews have explored the changing landscape. This study aims to obtain an overview of rural development research by applying a bibliometric and visual analysis. In this paper, we introduce four computer-based software tools, including HistCite™, CiteSpace, VOSviewer, and Map and Alluvial Generator, to help with data collection, data analysis, and visualization. The dataset consists of 6968 articles of rural development research, which were downloaded from the database Web of Science. The period covers 1957 to 2020 and the analysis units include journals, categories, authors, references, and keywords. Co-occurrence and co-citation analysis are conducted, and the results are exported in the format of networks. We analyze the trends of publications and explore the discipline distribution and identify the most influential authors and articles at different times. The results show that this field of study has attracted progressively more scholars from a variety of research fields and has become multidisciplinary and interdisciplinary. The changing knowledge domains of rural development research also reflect the dynamics and complexity of rural contexts.

Будучи одним из самых самобытных музыкантов начала ХХ века, Комитас претворил в своем искусстве ряд характерных для этого времени художественных идей, наиболее примечательные из которых связаны с музыкальным фольклоризмом и с понятием хронотопа. Блистательное композиторское мастерство Комитаса выводило его очень далеко за пределы привычных представлений о жанре фольклорной обработки. Глубокое проникновение в дух и законы родной музыкальной речи позволяло ему широко применять методы полифонической обработки народных мелодий, активно развивать фактуру сопровождения, которая в ряде случае приобретала самостоятельную художественную ценность. Самобытность песен и хоров Комитаса в ряде случаев определяется связью с восточным миросозерцанием, для которого в сравнении с европейским менталитетом характерно особое восприятие времени и пространства. При этом наибольший интерес представляют те образцы, где раскрывается сопричастность к категориям всеобщей материи и вечности. Особенно широко представлено в творчестве Комитаса погружение в природную сферу с растворением в ней человеческого начала. Восхождение к надвременным категориям композитор чаще всего совершает, когда делает основой сочинений фольклорные мелодии, пришедшие из толщи времен и запечатлевшие в себе устойчивые, коренные черты народного характера. Особым достижением Комитаса является то, что он не ограничивается претворением пантеистического и надвременного как отдельных сущностей. В ряде сочинений композитор дает их в соединении, чему опять-таки способствовали особенности восточного понимания хронотопа. Being one of the most original musicians of the early 20th century, Komitas has put into his art a number of typical for this time of artistic ideas, the most notable of which are associated with the musical folklorism and with the concept of the chronotope. His brilliant compositional skills took him far beyond the usual ideas about the genre of folklore processing. A deep insight into the spirit and laws of his native musical speech allowed him to widely apply the methods of polyphonic processing of folk melodies, actively develop the texture of accompaniment, which in some cases acquired an independent artistic value. The identity of Komitass songs and choirs is in some cases determined by the connection with the Eastern worldview, which is characterized by a special perception of time and space in comparison with the European mentality. At the same time, the most interesting are the samples, which reveal participation in the categories of universal matter and eternity. Especially widely represented in the works of Komitas deep immersion in the natural sphere with the dissolution of the human principle in it. The ascent to supra-temporal categories the composer often does, when making the basis of the works of folk tunes, came from strata of the times and depicting in a sustainable, indigenous features of the national character. A special achievement of Komitas is that it is not limited to the implementation of the pantheistic and supra-temporal as separate entities. In a number of works the composer gives them in conjunction, which again contributed to the features of the Eastern understanding of the chronotope.

The “child as scientist” metaphor has been a source of many important insights about how children learn about the world. Extensive research has shown that, like scientists, children construct and test theories about the world through observation, exploration, and experimentation. What is not known, however, is whether children are similar to scientists in their employment of thought experimentation and other rationalistic processes when trying to learn about the world. Although the history of science has documented many instances of thought experiments being central to conceptual revolutions, there have been no empirical studies that ask the same question within developmental psychology. Such empirical studies are needed and warranted. Contrary to popular belief, children’s imagination is not fanciful or poorly disciplined. Instead, their imagination is constrained by knowledge of causal principles across different domains. Thus, engaging children in thought experiments should not produce unrealistic or impossible outcomes; rather, it should produce outcomes consistent with the causal structure of the world. Indeed, the consideration of hitherto unacknowledged implications of such outcomes may teach children something new about the world. This chapter reviews evidence from several studies that were not originally designed to test whether children can benefit from thought experiments but which nonetheless provide encouraging preliminary evidence of such benefit. Somewhat surprisingly, they hint that at least under some circumstances, the benefit from thought experiments may be greater than the benefit from direct observations of the world.

Summary: Borderline personality disorder (BPD) is a frequent disorder in in- and outpatient settings. However, empirical studies suggest that BPD lacks construct validity in adolescents. Problems with validity may be linked to the fact that borderline symptoms can occur in the course of normal adolescence. This study examined the factor structure of borderline symptomatology in a community-based sample of 616 adolescents (mean age = 16.9±1.5). Borderline symptomatology was assessed by the Borderline Personality Inventory (BPI), a self-report instrument for which reliability and validity have been demonstrated. An exploratory factorial analysis, which was performed on the first half of the sample, extracted six factors. They were the dissociative/psychotic symptoms factor, the substance use factor, the interpersonal instability factor, the affectivity/identity disturbances factor, the narcissistic features factor, and the impulsivity factor. This six- factor model was tested using a confirmatory factorial analysis on the second half of the sample and on the whole sample. It provided an adequate fit with the data. This factor structure captured central components of borderline symptomatology. As it differs from the one obtained in the study of the BPI in adults, these components may be specific to adolescents and reflect developmental issues rather than psychopathology.

Fernando Ortiz is recognized today as one of the most influential Latin American authors of the 20th century. Amazingly prolific, his publications written between the 1890s and the mid-1950s engage with a vast array of subjects and disciplines. Perhaps Ortiz’s most significant accomplishments were the creation of the field of Afro-Cuban studies and major early contributions to the emergent field of Afro-diasporic studies. Almost everyone else associated with similar research began their investigations decades after Ortiz and in dialogue with his work. Ortiz was one of the first to seriously examine slave and post-abolition black cultures in Cuba. His studies became central to new and more positive discourses surrounding African-derived expression in the mid-20th century that embraced it as national expression for the first time in Latin America. This essay considers Ortiz’s academic career and legacy as regards Afro-Cuban musical study beginning in the early 20th century (when his views were quite dated, even racist) and gradual, progressive changes in his attitudes. Ortiz’s work on music and dance have been underrepresented in existing academic literature, despite the fact that most of his late publications focus on such topics and are considered among his most valuable works. His writings on black heritage provide insight into the struggles within New World societies to overcome the racial/evolutionist ideologies that justified colonial subjugation. His scholarship resonates with broader debates throughout the Americas over the meanings of racial pluralism and the legacy of slavery. And his changing views over the years outline the trajectory of modern Western thought as regards Africa and race, specifically the contributions of Afro-diasporic peoples, histories, and cultures to New World societies.

Variability or dispersion plays an important role in any process and provides insight into the spread of data from some central point, usually the mean. A process with less spread is preferred over a process in which values differ greatly from the mean. Various methods are available to estimate the process dispersion by using information on the variable of interest. Certain additional variables provide good insight to estimate the process dispersion. In this paper, we propose an efficient method for the estimation of process variability by using the exponential method. The properties of the proposed method were studied. We conducted simulation and empirical studies to compare the proposed method with some existing methods of estimation of variability. The results of the numerical study show that our proposed method is better than the other methods used in the study.
