Uppermost Ordovician and Silurian geology of north-west Peary Land, North Greenland
Authors: Hurst J.M
Published: June 2021

In 1978 mapping was concentrated in the area of Peary Land, between J. P. Koch Fjord and Odins Fjord, south of a line connecting Nordpasset with Harebugt and the western end of Frederick E. Hyde Fjord (fig. 11 and map l). Prior to this season the Silurian geology of the area was largely unknown. Previous investigations of the platform sediments of Peary Land (Koch, 1923; Troelsen, 1949, 1956; Jepsen, 1971) had mainly concentrated on the older Lower Palaeozoic and Precambrian rocks of southern Peary Land. The only comprehensive account of the Lower Palaeozoic rocks of the platform (including Silurian) of Peary Land, by Peel & Christie (1975) and Christie & Peel (1977) was based on a single composite section in the Børglum Elv district, north of Jørgen Brønlund Fjord (fig. 11). A localised detailed study of a Silurian carbonate buildup in the Børglum Elv region (Mayr, 1976) is the only other aspect of Silurian geology studied in the whole area.
Precambrian–Silurian geology of the G.B. Schley Fjord region, eastern Peary Land, North Greenland
Authors: Christie R.L , Ineson J.R
Published: June 2021

A structurally complex region of mainly sedimentary rocks lies north-east of the exposures of Silurian flysch in eastern Peary Land, in the vicinity of G. B. Schley Fjord (map l). South-easterly structural and sedimentary trends follow the edge of the flysch belt in a general way, so that older rocks tend to be exposed north-eastwards, towards the coast. An irregular outcrop pattern results, however, principally from numerous major and minor faults that cut the land in virtuaIly all directions. Three and possibly more geological sequences are present: (l) Precambrian rocks, comprising both sedimentary and volcanic types; (2) late Precambrian? to Silurian, beginning with a dolomite formation and ending with flysch sandstone; and (3) late Palaeozoic and younger rocks, forming part of the Wandel Sea Basin which occurs as down-faulted sedimentary outliers in the older terrains. The latter sequence is described by H~kansson, this report. Prior to the present field season, the principal geological investigation of the G. B. Schley Fjord region was that by J. C. Troelsen, a member of the Danish Peary Land Expedition (1947-1950). Troeisen (1956a) established the presence of several of the rock units discussed below. Additional remarks were published by Troelsen (1956b) and Peel, Dawes & Troelsen (1974).
Carboniferous to Tertiary development of the Wandel Sea Basin, eastern North Greenland
Authors: Håkansson E
Published: June 2021

This paper presents a report on the first systematic mapping in the northem half of the Wandel Sea Basin carried out in 1978. Due to unfavourable weather conditions along the north-east coast of Peary Land, only 20 days of actual fieldwork were achieved. The Wandel Sea Basin comprises a series of Carboniferous to Paleocene rocks in eastern North Greenland (Dawes & Soper, 1973). Previous visits to the northem part of the basin have been very brief (Koch, 1929a; Troelsen, 1950, 1956; Håkansson & Heinberg, 1977) and only in the southern part is the basin known in any detail (Dawes, 1976).
Nagssugtoqidian tectonics at the western end of the Itivdleq shear zone, West Greenland
Authors: Nash D
Published: June 2021

From field work, centred around the settlement of Itivdleq, a pieture of the Nagssugtoqidian deformation in thjs area is presented (fig. 1). Major structure-forming movements occurred under high-grade metamorphic conditions (amphibolite-facies) and are divided into two stages. During the second stage a swarm of basic dykes, the Kangamiut dykes, were emplaced.
Controls of metamorphic grade in shear belts
Authors: Grocott J
Published: June 2021

The relationship between metamorphic grade and deformation is examined for shear belts occurring in Precambrian shields. A particular case, where isotherms have fallen continuously relative to an originally horizontal datum surface, for some time prior to the initiation of the shear belt and throughout its life, is examined in detail. Such behaviour of isotherms appears to be common. A type of syn-tectonic metamorphic boundary occurring within shear belts and not coinciding with a strain gradient is discussed in detail. Such boundaries are called active facies boundaries, as mineral assemblages on each side tend to maintain perfect equilibrium with metamorphic conditions during deformation. The orientation of active facies boundaries depends on the vertical displacement rate. In ductile thrust zones horizontal gradients in metamorphic conditions can be set up, and folIowing erosion once active facies boundaries may be exposed. The metamorphic history of rocks in such zones will vary vertically, and, under certain circumstances, laterally. A model is set up to predict these variations, and is applied to the northem boundary of the Ikertoq shear belt, western Greenland.
An interpretation of irregular dyke form in the Itivdleq shear zone, West Greenland
Authors: Nash D
Published: June 2021

Around the settlement of Itivdleq the general form of the Kangamiut dykes varies according to whether the intrusions occur within or outside the pre-dyke Itivdleq shear zone (fig. 1; Nash, this volume). Outlined below is an interpretation of the origin and development of the different dyke forms in the shear zone and some brief remarks on the significance of the results.
Nagssugtoqidian granulite facies metamorphism in the Holsteinsborg region, West Greenland
Authors: Davidson L.M
Published: June 2021

The rocks of the Holsteinsborg district were subjected to conditions of granulite facies metamorphism throughout and for some time after the period of ductile Nagssugtoqidian deformation. Within this span of time the pressure and temperature conditions did not remain stable and may be shown to have varied considerably. Zoning of Al in orthopyroxene coexisting with garnet, and of Mg and Fe in coexisting orthopyroxene and garnet, and clinopyroxene and garnet are interpreted as evidence of gradual cooling folIowing the peak of metamorphism. Zoning of Ca and AI in coexisting c1inopyroxene and plagioclase is interpreted as an indication of decreasing pressure. The assemblage orthopyroxene, sillimanite and quartz was stable during the peak of Nagssugtoqidian metamorphism and is considered to indicate extreme conditions, approaching 900·C, 9.5 kbar. Pyroxene thermometry suggests that peak temperatures exceeded 800 C.
Rb-Sr isotope evidence on the age of the Nagssugtoqidian orogeny in West Greenland, with remarks on the use of the term 'Nagssugtoqidian'
Authors: Kalsbeek F
Published: June 2021

According to the original definition, the Nagssugtoqidian orogeny took place after the intrusion of the Kangamiut dykes in West Greenland (Ramberg, 1948). Two of these dykes have been dated recently and gave a Rb-Sr whole-rock isochron age of 1950 ± 60 m.y.* (Kalsbeek et al., 1978). On the basis of petrographic and (isotope-) chemical criteria it was argued that this age dates the intrusion of the dykes and not a much later metamorphism, and this conclusion is supported by other lines of evidence (see Kalsbeek et al., 1978). A lower age limit for the Nagssugtoqidian metamorphism is given by K-Ar biotite ages in the range of 1600-1800 m.y. (e.g. Larsen & Møller, 1968). The post-dyke Nagssugtoqidian metamorphism thus took place between c. 2000 and c. 1800 m.y., perhaps continuing to c. 1600 m.y.
Comments on protection of geological sites in Greenland
Authors: Ellitsgaard-Rasmussen K
Published: June 2021

Greenland is a large land with unique arctic nature which also offers just as unique opportunities to the geologist. The rocks range from the very oldest Precambrian to the most recent glacial deposits. The degree of weathering is minimal and fresh outcrops can be studied nearly everywhere. Greenland has attracted scientists from all over the worId for many years and has become a centre of international geological research.
Gravity and rock densities in the Ilímaussaq area, South Greenland
Authors: Forsberg R , Rasmussen K.L
Published: June 2021

Early gravity measurements in South Greenland (Kejlsø, 1958; J. Olsen, personal communication) indicated a large positive Bouger anomaly around Narssaq. Newer terrain-corrected gravity data obtained by the Geodetic Institute as part of regional surveys in the Julianehåb and Godthåb regions showed this anomaly to be approximately over the Ilimaussaq alkaline intrusion. The anomaly is interesting not only because of its size, but also due to the lack of similar anomalies over other Gardar intrusions, such as the Igaliko complex.
Rb/Sr age of the Kap Washington Group, North Greenland, and its geotectonic implications
Authors: Larsen O , Dawes P.R , Soper N.J
Published: June 2021

The Kap Washington Group is a bedded suite of rhyolitic lavas and tuffs that forms the northernmost rock province of Greenland (Dawes & Soper, 1973). The volcanic group borders on the north the Palaeozoic North Greenland fold belt from which it is separated by the southerly-dipping Kap Cannon thrust (fig. 38). K/Ar whole-rock age determinations of 34.9±5.3 m.y. and 32.3±3.2. m.y. on somewhat mylonitised lava samples were earlier regarded as giving an approximate minimum age of vo1canic consolidation and a maximum age of the Kap Cannon thrusting (Dawes & Soper, 1971). This note reports on Rb/Sr isotopic work that dates the Kap Washington Group, the five samples proeessed suggesting an age of about 63 m.y. Thus the general age of extrusion and con olidation of the vo!canie pile is eonsidered to be earlie t Tertiary.

Ceratopea (Gastropoda) from Washington Land, western North Greenland
Authors: Peel J.S , Yochelson E.L
Published: June 2021

Ceratopea unguis is described from the Nunatami Formation of Washington Land, western North Greenland, confirming a late Canadian (Iate Early Ordovician) age. A correlation is thus established between the Nunatami Formation and the Wandel Valley Formation of Peary Land, eastern North Greenland, which also yields C. unguis.
Ground magnetic investigations in the Godthåbsfjord region, southern West Greenland
Authors: Thorning L
Published: June 2021

As a continuation of aeromagnetic surveys (Thorning, 1976, 1977) and subsequent fieldwork (Thorning et al., 1978), ground magnetic investigations were carried out in the Godthåbsfjord region. More detailed work concentrated on specific magnetic anomalies located during the airborne surveys (Mielby & Svendsen, this report). Fig. 23 indicates the areas visited during summer 1978.
Field work on the Nagssugtoqidian boundary north of Angmagssalik and Tertiary igneous rocks of Kialineq and Kap Gustav Holm, East Greenland
Authors: Myers J.S , Austrheim H , Gill R.C.O , Gorman B.E , Rex D.C
Published: June 2021

Work was carried out from the 80 ton cutter Tycho Brahe using 16 ft inflatable rubber dinghies between 24th July and 31st August 1978. In addition, the Nagssugtoqidian boundary was mapped westwards from Kangerdlugssuatsiaq to the inland ice cap by Bell 204 helicopter and part of the Kialineq region was mapped from a Piper Navajo aircraft (fig. 28). The Nagssugtoqidian boundary was examined on the north shore of Kangerdlugssuatsiaq and a section through the northem part of the Nagssugtoqidian mobile belt was mapped along the shores of the upper part of Sermilik by rubber dinghy. Part of the Angmagssalik charnockite complex was examined in detail around Angmagssalik and Kap Dan. The Tertiary plutonic centres of Kialineq and Kap Gustav Holm were mapped in detail as well as the coastal dyke swarm in these regions, and samples were collected from all the main plutonic units for petrology and isotope studies.
The status of the Neoglacial in western Greenland
Authors: Kelly M
Published: June 2021

The evidence relating to the Neoglacial history of the western sector of the Greenland lee Sheet is critically examined. It is concluded that glacierisation began to increase about 3000-3500 B.P. from a significantiy smaller extent than at present, but that in general this does not appear to have reached its maximum until the recent post-1000 B. P. advances. What little reliable evidence there is of greater early Neoglacial events ean be considered to represent local, anomalous developments. It is emphasised that this model should be regarded as a working hypothesis which will be modified by future work.
The tholeiitic and komatiitic affinities of the Malene metavolcanic amphibolites from Ivisârtoq, southern West Greenland
Authors: Hall R.P
Published: June 2021

The chemistry of a suite of representative samples of the various Malene amphibolite Iithologies from Ivisârtoq has been analysed by X-ray fluorescence (XRF) techniques. The major element chemistry of the amphibolites is very variable and is compared to that of amphibolites from other Archaean terrains and to modem basaltic lavas. Pillow-structured and intercalated homogeneous horizons prevail among the amphibolites of Ivisârtoq. These predominant units comprise a suite which ranges chernically from abyssal tholeiite through to basaItic and pyroxenitic komatiite in character, and chromium and nickel contents are in accordance with this classification. The well preserved pillow structures indicate that these rocks originated as subaqueous basic and ultrabasic lavas, and include the first reported ultramafic pillows in the Archaean of southern West Greenland.

Geological reconnaissance in the Caledonian foreland of eastern North Greenland with comments on the Centrum Limestone
Authors: Peel J.S
Published: June 2021

During the latter half of the 1979 field season, geological reconnaissance was undertaken in eastern North Greenland (fig. 30), in the foreland to the Caledonian mountain chain, as a preliminary to mapping programmes planned for 1980. The principal aim of the reconnaissance was to study a cross-section from Danmark Fjord to Romer Sø (fig. 30) in Kronprins Christian Land and to establish a local stratigraphy suitable for map compilation. In addition, the northern part of Valdemar Gliiekstadt Land (fig. 30) was visited to investigate reports of Ordovician and Silurian strata in an area whieh preliminary mapping during 1978 had indicated as earliest Cambrian and Precambrian.

The challenge that has often occurred in recent years is making access to education using a different learning process path. The presence of technology now provides solutions to problems that often occur such as communication, accessing information, and business or cooperation. Blockchain is a technology that develops an evaluation model for itineraries in the learning process, both individually and in bulk. Currently the Edublocs project has been designed and implemented, which combines elements of peer-to-peer learning and the teaching team. The aim of the Edublocs project is to simplify the process of designing and implementing a system for recording activity results through blockchain technology. This ongoing project is in the process of evaluation. Conforming to some design elements as well as experimental implementation in the context of higher education enables us to further indicate the sustainability and relevance of the application of blockchain technology in education.

Гастроезофагеальна н. ексно хвороба (ГЕРХ) – од-не з найпоширеніших, потенційно небезпечних гаст-роентерологічних захворювань, яке, за визначенням Всесвітньої організації охорони здоров’я (ВООЗ), вважається хворобою ХХІ століття.Вивчення особливостей тканин ротової порожнини при різних соматичних захворюваннях, зокрема на тлі ГЕРХ, має велике діагностичне значення та сприяє кращому розумінню патогенетичних механізмів їх взаємозв’язку, який свідчить не тільки про н. екснфічні відношення між ротовою порожни-ною та кишечною трубкою, але і про тісний рефлек-торний та гуморальний зв’язок слизової оболонки по-рожнини рота, шлунку та кишечника. Відомо, що у патогенезі захворювань ротової порожнини важливу роль посідає зростання інтенсивності перекисне оки-слення ліпідів (ПОЛ) та недостатній рівень активно-сті антиоксидантного захисту клітин (АОЗ). Саме аномальне утворення продуктів ПОЛ виступає поча-тковим етапом молекулярних пошкоджень клітин.Нами було проведено дослідження по вивченню стану перекисного окислення ліпідів (ПОЛ) та антиоксида-нтного захисту клітин (АОЗ) та розробці профілак-тичного комплексу для попередження розвитку за-хворювань ротової порожнини при н. ексн, шляхом моделювання н. ексн у щурів. В результаті було зроблено висновок, що сукупність гастроезофагеаль-ної н. ексної хвороби та карієсогенного раціону має негативний вплив на антиоксидантний та про-тизапальний захист організму, натомість застосу-вання лікувально-профілактичного комплексу призво-дить до покращення показників антиоксидантного захисту клітин.

При цьому переломи нижньої щелепи займають друге місце по частоті серед усіх переломів щелепно-лицевої ділян-ки.Найчастіше переломи щелепно-лицевої ділянки у ді-тей трапляються у періоди 6-7 років – час початку відвідування школи, 12-14 років – значне зростання фізичної активності, участі у спортивних змаганнях та тренуваннях, 16-18 років – хуліганські травми. За даними наукових джерел, частота виникнення пере-лому різних відділів нижньої щелепи варіюється.Мета даного дослідження. Підвищення ефективно-сті лікування переломів кута нижньої щелепи у дітей 6-8 років шляхом визначення оптимального місця для фіксації мініпластин за допомогою аналізу комп’ютерних томограм.Матеріали та методи дослідження. Нами було про-ведено аналіз історій хвороб дітей з переломами ку-тів нижньої щелепи, які лікувались шляхом остеоси-нтезу у щелепно-лицевих відділеннях міських лікарень м. Дніпро за період з 2012 по 2020 роки. Проведений нами аналіз 23 томограм дітей 6-8 років виявив мак-симально близьке розташування нижньощелепного каналу у 100 % випадків. Після вивчення ортопанто-мограм та комп’ютерних томограм обстежених ді-тей із змінним прикусом нами було розроблено власну методику фіксації мініпластини. Нами було запропо-новано та відпрацьовано методику фіксації мініпла-стини по зовнішній косій лінії з чотирма точками свердління для гвинтів в безпечних зонах.Одним із основних етапів успішного лікування пере-ломів кута нижньої щелепи у дітей 6-8 років мето-дом остеосинтезу являється обґрунтування розта-шування гвинтів для фіксації мініпластин.

У час стрімкої гаджетизації дітей, в тому числі і дошкільного віку, мотиваційним кроком є залучення мобільних додатків для поліпшення кратності та якості гігієнічних навичок. На ринку представлені рі-зновікові, мультифункціональні мобільні додатки, такі як: Dental Care APP, Oral-B APP, CavityFree 3D, Sonicare for kids. Вони не тільки мають просвітниць-ку функцію, а й надають рекомендації при введені не-обхідних даних.Мета дослідження. Оцінити рівень гігієни ротової порожнини дітей та поліпшити її шляхом застосу-вання спеціалізованих мобільних додатків.Матеріали і методи дослідження. Нами проведено огляд різних мобільних додатків для операційних сис-тем Android та IOS, із функцією навчання санітарної стоматологічної грамотності, та вибрано найбільш ефективні. Задля визначення ефективності викорис-тання мобільних додатків із метою поліпшення гігіє-ни ротової порожнини ми визначали рівень гігієни за індексами Грін-Верміліона та Podshadley, Haley при першому візиті, через 1, 3 та 6 місяців у 73 дітей ві-ком 6 років, що проживають на Буковині. Ми сфор-мували 2 групи: основну – діти, які під час чищення зубів використовували мобільні додатки, та порівня-льну – діти, які під час чищення зубів не використову-вали мобільні додатки. Дітям обох груп дано рекоме-ндації щодо вибору засобів та предметів гігієни, про-ведено навчання гігієні.Результати. Результати опитування вказують на недостатню увагу дітей до гігієни ротової порожни-ни: двічі на добу чистять зуби тільки половина рес-пондентів, зранку – кожна п’ята дитина обох груп. Перед сном доглядає за ротовою порожниною майже кожна третя дитина.Аналіз гігієни ротової порожнини на момент обстеження показав низький рівень гігієни ротової порожнини. За отриманими нами даними індекса Грін-Верміліона в дітей основної та порівняльної груп виявлена задовільна гігієна ротової порожнини. Се-реднє значення гігієнічного індекса в дітей основної підгрупи через місяць застосування мобільних додат-ків під час чищення зубів становило 0,54±0,03 бали, що на 56,80 % нижче показників групи порівняння (p1˂0,05). Отримані результати вказують на добру гігієну ротової порожнини і утримуються на такому ж рівні і у віддалені терміни. У динаміці спостере-ження через 1 місяць за індексом Podshadley, Haley стан гігієни ротової порожнини в дітей основної групи був добрий і становив 0,47±0,03 балів. Вірогідна відмінність порівняно з вихідним станом та добрий рівень гігієни спостерігалися також у віддалені тер-міни.Висновки. Упровадження в практику щоденного чи-щення зубів у дітей мотивуючих чинників, таких як мобільні додатки з функцією санітарного стомато-логічного навчання, дає можливість суттєво поліп-шити гігієну ротової порожнини, що підтверджу-ється вірогідно нижчими показниками гігієнічного ін-дексу у віддалені терміни.
Small Rural Schools: Unique Challenges, Unequal Treatment -- A Policy Analysis
Authors: Atkinson V. Sue
Published: June 2021

The problems and challenges of rural education, made yet more challenging by the persistence of rural poverty, remain largely out the public eye but in need of policy solutions. Rural schools face inequities in the form of discrimination under current Title I funding allocation formulas, and school reform efforts to date have been a poor fit for rural districts. Nevertheless, students in rural schools achieve high test scores and a graduation rate approaching that of suburban schools, but attend college at much lower rates. Rural areas, and hence rural schools, face challenges of declining population and school enrollment, consolidation pressures, and an eroding economic base that is both a cause and an effect of youth out-migration. The problems of rural areas and rural schools are stereotyped, ignored, or exploited by policymakers. Consequently, rural schools are under-served by current education policies and initiatives, and their students left behind. This policy analysis concludes with recommendations aimed at multiple stakeholders to work toward revitalizing rural schools and communities.

Three-Factor and Five-Factor Models: Implementation of Fama and French Model on Market Overreaction Conditions
Authors: Sembiring Ferikawita M.
Published: June 2021

Objective - Previous research by this author has stated that the market overreaction phenomenon occurs in the Indonesian capital market and the CAPM (Capital Asset Pricing Model) is able to explain portfolio returns. However, CAPM is still debated along with the emergence of the other asset pricing models, such as the multifactor model proposed by Fama and French. The aim of this research is to test the ability of that model to explain the returns of portfolios formed under market overreaction conditions.

Methodology/Technique - The data used in this study is the same as that of the previous research, which includes winner and loser portfolio data formed in market overreaction conditions, particularly on the Indonesian Stock Exchange, between July 2005 and December 2015. The multifactor models used include a three-factor model consisting of the factors of market, firm size, firm value, and a five-factor model with the added factors of profitability and investment. To obtain more accurate results, GARCH econometric models were also used in addition to standard test models for obtaining unbiased results.

Findings - This research concludes that market factors (Rm-Rf), firm size (SMB), and firm value (HML), are able to explain the winner and loser portfolio returns well. However, when the factors of profitability (RMW) and investment (CMA) are added into the three-factor model, the RMW and CMA explained the returns negatively and inconsistently when the GARCH model is implemented.

Novelty – These results imply that the three-factor model is more accurate than the five-factor model, contrary to the previous findings of Fama and French.

Firm Value, Firm Size and Income Smoothing
Authors: Pradipta Arya , Susanto Yulius Kurnia
Published: June 2021

Objective - Income smoothing is a form of earnings manipulation to show that the company's performance is good. Income smoothing can be detrimental to investors, because investors do not know the real financial position and fluctuations of the company. Management of the company engage in income smoothing because investors tend to focus only on the amount of profit reported without regard to the process of generating profits. The purpose of this research is to obtain empirical evidence about the effect of firm value and size on income smoothing.

Methodology/Technique - The sample of the research includes manufacturing companies listed on the Indonesian Stock Exchange from 2014-2016. The samples were determined using a purposive sampling method and there are 51 companies that meet the criteria used. This research uses a logistic regression method for data analysis.

Findings - The results of the research show that the effect of firm value on income smoothing is positive and significant. Meanwhile, the effect of firm size on income smoothing is negative and significant. Companies that create value in the eyes of investors will try to retain their investors by engaging in income smoothing. Income smoothing will convince investors to invest in the company. Meanwhile, large companies that are convinced that investors will continue to invest do not typically engage in income smoothing.

Novelty – This study proves that, in the context of agency theory, the principal's desires are not often aligned with the wishes of management which can give rise to agency costs, one of which occurs as a result of income smoothing. Further, firm size can minimize opportunist income smoothing actions.

Type of Paper - Empirical.

Keywords: Income Smoothing; Firm Value; Firm Size; Agency Theory.

Commitment in WAQF Development through Cross-Sector Collaboration between Islamic Financial Institutions and State Islamic Religious Councils: Innovative Strategy of Value-Based Intermediation for Sustainability
Authors: Ibrahim Siti Sara Binti , Noor Abd Halim Mohd , Ismail Shafinar , Arshad Roshayani , Don Mohd Ali Muhamad
Published: June 2021

Objective - Islamic Financial Institutions (IFIs) are founded upon principles of encouraging economic wellbeing for the betterment of society. Despite this, fresh measures are required to ascertain the sustainability of IFIs due to the deterioration recorded in annual rate growth levels that has slumped to 8.2% in 2016, compared to 24.2% in 2011. Similarly, waqf, which aims to contribute to socio-economic growth, appears to underperform due to inefficient management and lack of resources from State Islamic Religious Councils (SIRCs) in Malaysia. Therefore, growing attention is given to adding value to related operations so as to continuously expand without undermining their obligation towards societal welfare.

Methodology/Technique - In responding to this issue, Value-Based Intermediation (VBI) through a cross-sector collaboration strategy has been proposed in this paper to streamline the investments of IFIs in executing their business responsibilities in a strategic manner, especially to generate sustainable socio-economic growth through waqf development projects. Nonetheless, in order to strategically perform in project collaboration for sustainability, strong commitment from IFIs and SIRCs is needed.

Findings - A significantly positive relationship was discovered between the independent variables (affective commitment, normative commitment, and continuous commitment) and organisational sustainability.

Novelty – The paper concludes with an assumption of the readiness of both organisations in effectively developing waqf projects, along with several recommendations for future studies in further contributing to the success of waqf development which will contribute to organisational sustainability.

Type of Paper - Empirical.

Effect of Stock Price Information on Timing of Share Repurchases
Authors: Chee Chong-Meng , Razak Nazrul Hisyam Bin Ab
Published: June 2021

Objective - This study investigates whether private information newly incorporated into stock price enhances performance in timing share repurchases. Methodology/Technique - Cost saving gained in share repurchases is used a proxy for performance of market-timing in share repurchases and firm-specific stock return variation is used to gauge stock price informativeness. A sample of 334 U.S. repurchasing firms are tested using panel data regression. Findings - The paper concludes that managers possess better market timing skill by obtaining more cost saving from their share repurchases when private information is reflected in stock price. Stock price informativeness may be the tool for managers to improve their market timing skill to take advantage of the stock market. Furthermore, firms with smaller size and a higher market-to-book ratios, and firms with higher cash-to-assets ratios are found to achieve more cost saving in buying back their shares indicating that these firms are able to time the market in share repurchasing. Novelty – Despite numerous previous studies focusing solely on using share repurchases announcement for computing cumulative abnormal returns in testing managerial market timing, this study contributes to the literature in several ways: (i) providing evidence relating stock price informativeness and performance of market-timing in share repurchases; (ii) developing a better timing measure constructed using actual repurchasing data; (iii) adopting a cost saving measure as the timing measure instead of cumulative abnormal return. Type of Paper - Empirical. Keywords: Managerial Learning Hypothesis; Market Timing; Stock Repurchase; Stock Price Informativeness; Firm-specific Stock Return Variation.

Rehabilitating Islamic Ethics
Authors: Swazo Norman K.
Published: June 2021

The debate between modernity and postmodernity in western discourses about law and morality calls for a similar debate in contemporary Islam. For Islam, the question is whether a rehabilitation of its classical discipline of ethics (`ilm al-akhlaq) may contribute to international morality even as it disabuses Islam of privileging Islamic jurisprudence (`ilm al-fiqh), which conceives of the Shari`ah as merely law. Islam’s strong tradition of ethical discourse is similar to the West’s classical and contemporary formulations of virtue ethics. Such a renewal constitutes a postmodern opportunity for contemporary Islam as it faces the globalization of western values and jurisprudence.

Authors: Vasilieva G.N. , Pletneva T.V. , Bornyakova E.V.
Published: June 2021

The article discusses the relevance of the implementation of lean production principles in higher education institutions and their impact on the educational process in pandemic conditions. The SQDCM format is considered as an effective model providing management by objectives, connection with safety, quality, costs, and corporate culture. Value is seen as the most important category of lean management, which serves as a basis for self -organization of faculty and staff, and students in higher education institutions. The authors pay attention to the process of lean principles’ implementation in educational process, with Udmurt State University setting an example. Since having formed the values over the recent years, Udmurt State University has been able to effectively change educational processes in the settings of epidemiological uncertainty that has arisen in pandemic in Russia and around the world. The authors conclude, that lean approaches to building a university management system allow to maintain student involvement in educational activities, to see new opportunities for interaction in organizing the educational process and to master new valuable competencies, thus, to maintain a high level of education quality.
