The aims of this study were to develop and validate an instrument to quantitatively assess the handedness of basketballers in basketball tasks (Basketball Handedness Inventory, BaHI) and to compare it with their handedness in daily activities by the Edinburgh Handedness Inventory (EHI). The participants were 111 basketballers and 40 controls. All subjects completed the EHI and only basketballers filled in the BaHI. To validate the BaHI, a voluntary subsample of basketballers repeated the BaHI. Exploratory and confirmatory factor analyses supported a two-factor model. Our results show that: (i) Handedness score (R) in daily actions did not differ between basketball players (R by EHI = 69.3 ± 44.6) and the control group (R by EHI = 64.5 ± 58.6); (ii) basketballers more frequently favored performing certain sport tasks with the left hand or mixed hands (as highlighted by R by BaHI = 50.1 ± 47.1), although their choice was primarily the right hand in everyday gestures; and (iii) this preference was especially true for athletes at the highest levels of performance (R by BaHI of A1 league = 38.6 ± 58.3) and for those playing in selected roles (point guard’s R = 29.4 ± 67.4). Our findings suggest that professional training induces handedness changes in basketball tasks. The BaHI provides a valid and reliable measure of the skilled hand in basketball. This will allow coaches to assess mastery of the ball according to the hand used by the athlete in the different tasks and roles.

The Specialty That Deals With Investigation Of Failures And Performance Problems In The Geotechnical Environment Is Known As Forensic Geotechnical Engineering. It Involves Scientific And Jurisprudence Related Investigations And Evaluation To Analyze The Causes Of Structural Distress That Originate From Geodomain. Forensics In The Geo-Domain Encompass An Extensive Array Of Topics With Specific Emphasis In Geotechnical Related Fields. Mostly, They Apply To Failures After They Occur. Such Analysis And The Evaluation Of Selected Remedial Measures, Along With Their Effectiveness And Economy, Are Normally Subjected To Judicial Scrutiny. A Case History Is Presented Where Forensic Engineering Was Effectively Utilized To Identify, Investigate, And Remediate The Problem As Well As Assist In Litigation.

Agency theory is the dominant theory of shareholder activism and argues that activist investors function as external governance monitors. Agency theory predicts that activist investors will tend to target firms who exhibit governance and performance problems. However, given limited resources and time, activist investors must often decide between selecting targets with particularly strong agency and performance problems and those where their activism efforts are most likely to succeed. Social movement scholars point out that, in social movement contexts, the corporate opportunity structure affects when and where activism is likely to arise. We draw on insights from social movement scholarship and agency theory to advance a theory of heterogeneity in shareholder activism. We argue that an activist’s access to power and resources shapes its target selection, particularly the activist’s preference for targeting firms with greater agency problems or where contextual factors favor chances of success. Whereas more powerful activists are able to wield their power as effective governance monitors against firms with substantial agency problems, less powerful activists must strategically select targets of opportunity by choosing firms where contextual factors improve their odds of success. We test these propositions using an innovative relational approach that can simultaneously incorporate firm traits, activist identities, and endogenous dynamics.

Пианист Пауль Витгенштейн, желая расширить и обновить свой концертный репертуар, внес в XX веке существенный вклад в фортепианную литературу для левой руки. В 1929–1930 годах он заказывает фортепианный концерт сначала Морису Равелю, а затем Сергею Прокофьеву. Это оказалось возможным благодаря наследству, полученному пианистом после смерти отца — сталелитейного магната Карла Витгенштейна. Если Равелю удалось, хоть и не полностью, удовлетворить потребности заказчика, то Прокофьеву было вовсе отказано в исполнении его музыки. Одной из главных причин неудачи Прокофьева можно считать творческий кризис конца зарубежного периода, когда композитор находился в поисках нового музыкального языка — «новой простоты». В статье прослеживается и сравнивается судьба этих произведений; устанавливаются причины сравнительной невостребованности концерта Прокофьева исполнителями; анализируется композиция, фортепианная фактура и техника, оркестровка. Освещены биографические факты из жизни Пауля Витгенштейна, а также непростые отношения между заказчиком и композиторами. In the twentieth century, the one-armed pianist Paul Wittgenstein made a significant contribution to piano literature for the left hand, which was due to his wish to broaden and update his concert repertoire. In 1929–1930 he ordered a left-handed piano concerto first to Maurice Ravel and then to Sergei Prokofiev. It was possible through the inheritance that Wittgenstein received after the death of his father, the steel magnate Karl Wittgenstein. While Ravel was able to meet the client’s needs, though not completely, Prokofiev was completely denied the performance of his music. One of the main reasons for Prokofiev’s failure might be the creative crisis of the end of the foreign period, when the composer was in search of a new musical language — “the new simplicity”. The article traces and compares the destiny of these piano concertos, specifying the reasons for the relative lack of demand for Prokofiev’s left-handed concerto on behalf of performers. The article also analyzes music, piano texture and technique, form, orchestration of the lefthanded concertos. Special attention is paid to biographical facts from Paul Wittgenstein’s life, as well as uneasy relationship between the client and the composers.

Associative Computation is characterized by intertwining of search by content and data parallel computation. An algebra for associative computation is described. A compilation based model and a novel abstract machine for associative logic programming are presented. The model uses loose coupling of left hand side of the program, treated as data, and right hand side of the program, treated as low level code. This representation achieves efficiency by associative computation and data alignment during goal reduction and during execution of low level abstract instructions. Data alignment reduces the overhead of data movement. Novel schemes for associative manipulation of aliased uninstantiated variables, data parallel goal reduction in the presence multiple occurrences of the same variables in a goal. The architecture, behavior, and performance evaluation of the model are presented.
