Strombidinopsis species were collected from theGulf of Alaska, Gulf of Mexico, Caribbean Sea, Gulf of Maine, and Barents Sea. Six strains were conservatively placed in six species: Strombidinopsis chilorhax sp. nov.; Strombidinopsis batos sp. nov.; Strombidinopsis sphaira sp. nov.;Strombidinopsis cercionis sp. nov.;Strombidinopsis acuminatum Fauré-Fremiet, 1924; and Strombidinopsis spiniferum (Leegaard, 1915) comb. nov. Based on the characters of these species, the diagnosis of the genus Strombidinopsis was revised.

В статье рассмотрен философский аспект развития государственных программ цифровизации разных стран. Дана характеристика категории «искусственный интеллект». Показаны особенности внедрения слабого искусственного интеллекта в социальные системы, в частности, в России, Китае и странах Запада. На примере COVID-19 рассмотрено принятие обществом мер государственного принуждения. Освещены вопросы вмешательства правительств в частную жизнь, влияния искусственного интеллекта на окружающую реальность. Приведены аксиологические основания различий в реакции разных народов на необходимость исполнения распоряжений органов власти.

Abstracts The Indian summer monsoon (ISM) precipitation pattern over Indian subcontinent is looked through various high resolution speleothem oxygen (δ18O) isotope records from Mid to Late Holocene. The six cave locations distributed from central to northern India describing regional climatic conditions due to stalagmite deposition are considered. The stalagmite deposition reflects precipitation patterns by temporal variations of δ18O values. Oxygen isotope values reflect cumulative precipitation that is basically interpreted by averaged latitudinal site of inter tropical convergence zone (ITCZ). Under the Paleoclimate Modelling Intercomparison Project Phase III (PMIP3) simulation, Commonwealth Scientific and Industrial Research Organisation Mk3L version 1.0 – Part 2 (CSIRO-Mk3L-1-2) model output shows ITCZ movement from Bay of Bengal (BoB) to Arabian Sea (AS) during Mid to Late Holocene which resulted due to solar insolation changes. It reflects precipitation shift from BoB to AS as well as to core monsoon zone (CMZ) to the western Himalayas. The past millennium epoch, which consists little ice age (LIA) and middle warm period (MWP), shows large variations in 850 hPa geopotential height leading to high anomalous precipitation variability all over India during ISM. The high fluctuation in δ18O values during Mid Holocene over northern India led to drought conditions due to which Indus valley civilization vanished. The present study shows that the Himalayas received higher precipitation during late Holocene. That is basically governed by western disturbances (WD) as well as ISM. Present study summarizes that the mean annual precipitation cycle for entire epoch was roughly similar, but spatial distribution of precipitation during various epoch was quite divergent from Mid to Late Holocene. The onset of ISM was also similar but, withdrawal was comparatively unalike. Wherever, peaks of seasonal precipitation were alike over Indian subcontinent region, spatial distribution of precipitation were unlike.

The study aimed to address the management and its impact on the age and tenure cohort at a higher education institution. An overview of what constitutes the characteristics of managers as well as a discourse between leadership and management skills is provided. The study adopted a mixed method design comprising a quantitative approach for employees and a qualitative approach for line management leadership and executive management leadership. The total population for the quantitative method constituted 1874 academic and administrative employees with a targeted sample of 420. The study obtained a response rate of 312 out of 420 employees. The qualitative data collection tools for the management were semi-structured interviews and open-ended interviews of 12 out of 18 being the realised sample size. The study showed evidence of poor leadership and management qualities in relation to support, role-modelling, trust, critical decisions, and self-management which may have a negative effect on younger and new employees. The study made an original contribution to this area as it depicted a clear indication of poor role-modelling and decision-making that managers lack, conflict management skills and its implications thereof.

A cobalt(III)-catalyzed coupling of substituted acrylamides with maleimides in the presence of 30 mol% pivalic acid providing olefin-migrated succinimide derivatives in a redox-neutral manner is described. The coupling reaction was examined with various substituted acrylamides and maleimides. The scope of the C–H alkylation reaction was also examined with substituted acrylates. A possible reaction mechanism involving a five-membered cobaltocycle as a key intermediate is proposed.
