Concurrent validity of the differential ability scales and the Woodcock-Johnson-III Tests of Cognitive Abilities for young children
No full textPlan BValidation studies assess how comparable intelligence instruments are with regard to the cognitive abilities they assess. Results derived from such studies are used to make inferences as to how instruments are similar and different regarding the abilities that they are designed to measure. This paper is a review and critical analysis of literature related to the validity of two intellectual assessment instruments often used with young children, the Differential Ability Scales (DAS) and the Woodcock-Johnson-Third Edition Tests of Cognitive Abilities (WJ-III COG). Topics covered in the literature review include issues regarding the assessment of young children, the importance of test validity, and the theoretical foundations of each instrument, as well as their practical use with young children. The purpose of this paper is to propose a study examining the concurrent validity of the DAS and WJ-III COG when used with a sample of young children receiving special education services for speech and language delays
Wealth, income, earnings and the statistical mechanics of flow systems
No full textThis paper looks at empirical data from economics regarding wealth, earnings and income, alongside a flow model for an economy based on the general Lotka-Volterra models of Levy & Solomon. The data and modelling suggest that a simple economic system might provide a tractable model for giving an exact statistical mechanical solution for an 'out of equilibrium' flow model. This might also include an exact mathematical definition of a 'dissipative structure' derived from maximum entropy considerations. This paper is primarily a qualitative discussion of how such a mathematical proof might be achieved.wealth; earnings; income; entropy; lotka; volterra; dissipative

Treść i dynamika objawienia imienia Bożego w Księdze Wyjścia Część I: Analiza narracji Wj 3,16–24,18
No full textThe article addresses the significance of the formulas of the Divine Name: יְהוָה, אֶהְיֶה אֲשֶׁר אֶהְיֶה, and אֶהְיֶה (Exod 3:14–15). Referring to the narrative character of the Book of Exodus and assuming that the ambiguous formulas of the Divine Name in the initial part of the story are elements of a deliberate literary strategy, the author proposes interpreting these formulas using a narrative method. An analysis of two narrative sections of the Book of Exodus (3:16–18:27; 19:1–24:18) reveals that God, whose presence is initially depicted as concealed, is later portrayed, through the presentation of the Name formulas, as manifesting His presence through active intervention. The narrated events, in which YHWH acts on behalf of the Israelites against their enemies (Exod 3:16–18:27) and subsequently leads them to covenantal commitment (Exod 19:1–24:18), present God-YHWH as being. This notion clearly aligns with the declaration embedded in the Name formulas.Artykuł podejmuje zagadnienie znaczenia formuł imienia Bożego: יְהוָה, אֶהְיֶה אֲשֶׁר אֶהְיֶה oraz אֶהְיֶה (Wj 3,14-15). Odwołując się do narracyjnego charakteru Księgi Wyjścia oraz przyjmując założenie, że niejednoznaczne formuły imienia Bożego w początkowej części opowieści stanowią element przemyślanej strategii literackiej, autor proponuje tłumaczenie tych formuł za pomocą metody narratywnej. Przeprowadzona analiza dwóch fragmentów narracji Księgi Wyjścia (3,16–18,27; 19,1–24,18) pozwala zauważyć, iż Bóg, którego obecność na początkowym etapie opowieści zaprezentowana zostaje jako niejawna, wraz z przedstawieniem formuł imienia, ukazany zostaje jako manifestujący swoją obecność w aktywnym działaniu. Opowiedziane wydarzenia, w których JHWH jest podmiotem działającym na rzecz Izraelitów przeciw ich wrogom (Wj 3,16–18,27), a następnie doprowadzającym ich do zawarcia przymierza (Wj 19,1–24,18), ukazują Boga-JHWH jako będącego, co w czytelny sposób koresponduje z deklaracją zawartą w formułach imienia
No evidence that severity of stroke in internal carotid occlusion is related to collateral arteries
No full textBackground/AimThe neurological effects of internal carotid artery (ICA) occlusion vary between patients. The authors investigated whether the severity of symptoms in a large group of patients with ipsilateral or/and contralateral ICA occlusion at presentation with ocular or cerebral ischaemic symptoms could be explained by patency of other extra or intracranial arteries to act as collateral pathways.MethodsThe authors prospectively identified all patients (n = 2881) with stroke, cerebral transient ischaemic attack (TIA), retinal artery occlusion (RAO), and amaurosis fugax (AFx) presenting to our hospital over five years, obtained detailed history and examination, and examined the intra and extracranial arteries with carotid and colour‐power transcranial Doppler ultrasound. For this analysis, all those with intracranial haemorrhage on brain imaging and cerebral events without brain imaging were excluded.ResultsAmong 2228/2397 patients with brain imaging (1713 ischaemic strokes, 401 cerebral TIAs, 193 AFx, and 90 RAO) who underwent carotid Doppler, 195 (9%) had ICA occlusion. Among those patients with cortical events, disease in potential collateral arteries (contralateral ICA, external carotid, ipsilateral or contralateral vertebral or intracranial arteries) was equally distributed among patients with severe and mild ischaemic presenting symptoms.ConclusionThe authors found no evidence that the clinical presentation associated with an ICA occlusion was related to patency of other extra or intracranial arteries to act as collateral pathways. Further work is required to investigate what determines the clinical effects of ICA occlusion
Treść i dynamika objawienia imienia Bożego w księdze Wyjścia Część II: Analiza narracji Wj 25,1-40,38
No full textThe article constitutes a continuation of the study addressing the significance of the formulas of the Divine Name: יְהוָה, אֶהְיֶה אֲשֶׁר אֶהְיֶה, and אֶהְיֶה (Exod 3:14–15). The analysis focuses on the subsequent textual material of the Book of Exodus (Exod 25:1–40:38), where YHWH is primarily portrayed as manifesting His presence in the Tabernacle, which He commands to be built as His dwelling place. Applying the method of narrative analysis to the entirety of the narrative material, the author concludes that the primary communicative aim of the book is to present God as being. This concept is signaled in the formulas of the Divine Name and confirmed throughout the narrative representation of the events. The depiction of YHWH’s presence intensifies progressively as the narrative unfolds, with God transitioning from an unknown name and imperceptible presence to being known by the name YHWH and permanently present among the Israelites.Artykuł stanowi kontynuację studium podejmującego temat znaczenia formuł imienia Bożego: יְהוָה, אֶהְיֶה אֲשֶׁר אֶהְיֶה oraz אֶהְיֶה (Wj 3,14-15). Analizie poddana zostaje dalsza partia materiału tekstualnego Księgi Wyjścia (Wj 25,1–40,38), gdzie JHWH zaprezentowany jest przede wszystkim jako manifestujący swoją obecność w przybytku, który nakazuje zbudować na mieszkanie dla siebie. Stosując metodę analizy narratywnej do całości materiału narracyjnego, autor dochodzi do wniosku, że głównym celem komunikacyjnym księgi jest ukazanie Boga jako będącego, co jest sygnalizowane w formułach imienia Bożego i potwierdzone w całej narracyjnej reprezentacji wydarzeń. Prezentacja obecności JHWH staje się coraz bardziej intensywna wraz z postępem narracji, a Bóg przechodzi od nieznanego imienia i niedostrzegalnej obecności do bycia znanym w imieniu JHWH i trwale obecnym pośród Izraelitów
Depth Control for Blind Water Jet Drilling in Bone
No full textAbstract - When surgically drilling blind holes in bone using a Water Jet (WJ), control over the resulting depth is a challenging issue of paramount concern. This thesis was part of a project aimed at replacing the awl and mallet technique used in traditional microfracture procedures with an arthroscopic high-pressure WJ instrument is capable of accurately drilling 2–4 mm deep holes in subchondral bone. The focus of this paper was to develop, analyze and evaluate concepts for ensuring the depthwise accuracy of a microfracturing WJ. Research was performed on both WJ systems and the microfracture procedure, and a thorough problem analysis detailing all concerning requirements and parameters was set up. It was determined that due to the strong non-uniformity of human bone, both spatially and between subjects, a WJ capable of monitoring the depth and implementing a closed-loop control system was needed to ensure safe and accurate drilling. To measure the depth of the hole and allow for feedback control, a flexible Nickel Titanium probe concept was devised and tested. The concept featured a 3D printed nozzle with built-in WJ orifice and depth probe, which could be extended down the hole made by the WJ by an ex-vivo actuator featurimg load and displacement sensors. When the load sensor detected a sudden rise in extension resistance, bottom contact was assumed and the hole depth was calculated based on the displacement of the probe. A proof-of-concept experiment showed the viability of using a flexible probe to measure the depth. Additionally, the algorithm produced for calculating the depth was shown to be robust against the hysteresis and backlash exhibited by the setup. When probing holes with depths of 0, 1, 2, 3, 4 and 5 mm and bore diameters of 1, 1.5, and 2 mm drilled in solid PMMA, the prototype managed an error mean of 0.00 mm with a SD of 0.19 mm. To test the probe in holes shaped as expected during microfracture surgery, a virtual interference experiment was carried out using mCT scans of WJ-drilled bones and simulated probes of varying diameters. Seven scans were probed from 4 different angles each; the results suggested that a probe with a 0.2–0.3 mm diameter was optimal in terms of traversing the hole without blockages and without risking over-penetration. Moreover, this thesis produced recommendations on carrying the project further, towards a fully integrated system capable of drilling accurate blind holes in human bone, in a closed-loop depth-controlled manner.BMEBioMechanical EngineeringMechanical, Maritime and Materials Engineerin
Mojżesz wysłannik Jahwe (Wj 1,1–14,31)
No full textThe Exodus of the Israelites from Egypt was the most important event in the history of the Chosen People. The historical and theological context of the biblical events contained in Exodus 1:1–14:31 was described.The aim of the research became the analysis and interpretation of the theological message contained in the first part of the Exodus recounting the liberation of the Israelites from Egyptian slavery (Exodus 1:1–14:31).In the analysis and exegesis of biblical texts, the intertextual method was used, as well as the historical-critical method over the issue of Moses’ mission.As a result of the study, it can be concluded that: 1) the knowledge of the God of Israel and His intentions is the key theme of the first fifteen chapters of the Exodus. Yahweh is the main protagonist of the events described in the Book of Exodus. He is their author and perpetrator; 2) the theme of the first part of the Exodus is the conflict over whom Israel is to serve; 3) the historical sources do not reflect in their entirety the facts known from the biblical account, for the reason that the Bible is not a historical chronicle, but a record of God’s revelation. Its main task is to convey theological content.The conclusions to be drawn are: 1) the revelation that was to Moses also applies to the Israelites, as well as to the Egyptians. However, the times and the manner of revelation change. God’s words are addressed to everyone, including modern people.The study conducted does not exhaust the subject of Moses’ mission to Israel. It is not a complete characterization of Moses. At the same time, it is necessary to keep in mind the further impact of the message of the Exodus on subsequent generations of Israel, as well as on modern times. The study can become a contribution to further theological reflection on the message of the Exodus.Wyjście Izraelitów z Egiptu było najważniejszym wydarzeniem w historii narodu wybranego. Został opisany kontekst historyczno-teologiczny wydarzeń biblijnych zawartych w Wj 1,1–14,31.Celem badań stała się analiza i interpretacja przesłania teologicznego zawartego w pierwszej części Księgi Wyjścia opowiadającej o wyzwoleniu Izraelitów z niewoli egipskiej (Wj 1,1–14,31).Przy analizie i egzegezie tekstów biblijnych wykorzystano metodę intertekstualną, a także historyczno-krytyczną nad zagadnieniem misji Mojżesza.W wyniku przeprowadzonych badań można stwierdzić, że: 1) poznanie Boga Izraela i Jego zamiarów jest kluczowym tematem pierwszych piętnastu rozdziałów Księgi Wyjścia. Jahwe jest głównym bohaterem wydarzeń opisanych w Księdze Wyjścia. On jest ich sprawcą i autorem; 2) tematem pierwszej części Księgi Wyjścia jest konflikt o to, komu służyć ma Izrael; 3) źródła historyczne nie odzwierciedlają w całości faktów znanych z relacji biblijnej, dlatego że Biblia nie jest kroniką historyczną, lecz zapisem objawienia Bożego. Jej głównym zadaniem jest przekaz treści teologicznej.Wnioski, jakie należy wyciągnąć to: 1) objawienie, które było do Mojżesza, dotyczą także Izraelitów, jak i do Egipcjan. Zmieniają się jednak czasy i sposób objawienia. Słowa Boga skierowane są do wszystkich, również do ludzi współczesnych.Przeprowadzone badania nie wyczerpują tematu misji Mojżesza względem Izraela. Nie jest pełną charakterystyką Mojżesza. Należy przy tym pamiętać o dalszym oddziaływaniu przesłania Księgi Wyjścia na kolejne pokolenia Izraela, a także na czasy współczesne. Badanie mogą stać się przyczynkiem do dalszej refleksji teologicznej nad przesłaniem Księgi Wyjścia
Pricing, liquidity and the control of dynamic systems in finance and economics
No full textThe paper discusses various practical consequences of treating economics and finance as an inherently dynamic and chaotic system. On the theoretical side this looks at the general applicability of the market-making pricing approach to economics in general. The paper also discuses the consequences of the endogenous creation of liquidity and the role of liquidity as a state variable. On the practical side, proposals are made for reducing chaotic behaviour in both housing markets and stock markets.dynamic, chaotic, liquidity, market-microstructure, post-keynesian
