description: With the enormous population growth and the ever-increasing use of various electronic devices in modern life, the proper disposal of the “Waste Electrical and Electronic Equipment” (WEEE) has been of paramount importance. The pervasive use of social media by customers has made governments and businesses use these platforms as a rich source of data to extract intelligence on consumer opinions. However, some scholars doubt the sufficiency of social media data concerning the design of a comprehensive list containing all influential factors on consumer behavior toward the proper treatment of WEEE. Thus, a mixed method of quantitative (by analyzing about 2,500,000 tweets from Twitter) and qualitative approaches (i.e. a literature thematic analysis followed by a three-phased Delphi method) has been adopted. Due to consumers’ different behavior based on their local status, the experts have been split into two different panels from developed and developing countries. They have also been provided with the findings from the literature along with the results from Twitter data analysis. The findings have revealed that economic incentives play a pivotal role in both categories. People in developing countries usually have concerns regarding socio-economic and socio-political issues, while in developed nations higher levels of influential factors exist, including proximity, suitability and ease of access, and so forth. The truth is that in order to have a green and pollution-free world, the whole world, whether developed or developing, must take joint steps to create public welfare, peace of mind and world peace. Otherwise, unilateral actions of countries will not have their desired effectiveness.

description: This paper presents a unified geometric framework for the statistical analysis of a general ill-posed linear inverse model which includes as special cases noisy compressed sensing, sign vector recovery, trace regression, orthogonal matrix estimation, and noisy matrix completion. We propose computationally feasible convex programs for statistical inference including estimation, confidence intervals and hypothesis testing. A theoretical framework is developed to characterize the local estimation rate of convergence and to provide statistical inference guarantees. Our results are built based on the local conic geometry and duality. The difficulty of statistical inference is captured by the geometric characterization of the local tangent cone through the Gaussian width and Sudakov minoration estimate.

description: This report summarizes the work developed under NET-Fuels WP4 (Sustainability and carbon sink assessment) Task 4.1 (Ensure reproducibility, transparency, and comparability of the sustainability assessment) in the period 01/11/2022 to 31/10/2023. Task 4.1 involves the creation of a common ground among the partners and a framework for sustainability assessments. In order to coordinate planned activities and foster communication and discussion among partners on preliminary and critical decisions, a document was created and shared among all partners. The document (which all partners had access to and could edit) served to have a shared virtual place where questions and concerns could be asked and answered. Along with the document, working sessions were held with all or part of the partners to work on specific issues.
The insights from the meetings, and the information shared and discussed in the shared document, are organized and summarized in this document. The task goal is to create a common knowledge base on which to build the next steps of the project. One among the objectives is to anticipate and answer questions and resolve any doubts that may later be obstacles to the progress of the planned activities.
In this document, a description of the framework for sustainability assessments is presented, including system boundaries, reference biofuel production systems, time horizon of the analysis, preliminary definition of the functional units, preliminary identification and selection of scenarios, preliminary decision about impact categories.
description: In this report, a summary of the main decisions is given in the following way:

NET-Fuels product system includes the exploitation of farm/forestry biomass and residual biomass, and generation of synthetic methane, oxygen, TCR crude bio-oil, hydrogen, biochar (with subsequent generation of immaterial carbon credits).
Target audiences include large industrial stakeholders and SMEs, the research community, and policy makers.
An ethnographic study of the NET-Fuels project and stakeholders mapping is to be integrated to the perspective system dynamic model.
Different time horizons will be used in the study, to have a prediction of the effects of the introduction of NET-Fuels technology but maintaining a certain degree of confidence in the data.
It was decided to use a product-oriented approach, and commensurate everything with the production of a given amount of synthetic methane.
Different scenarios and product system variations have been identified.
Protecting Police Officers Against Burnout: Final Report

Publisher: name: Griffith University
Year: 2018

description: Police officers play a significant role within society; however, their roles can be highly challenging and stressful. Continued exposure to stress is a risk factor for burnout, and prior research suggests that police officers are at high risk of burnout and work disengagement. First responder organisations place a large emphasis on interventions and resources promoting psychological wellbeing, and the management of psychosocial risks, known as psychosocial safety climate. This project aligns with the QPS’s strategic objective to “future-proof the workforce” by investigating the resources which protect police officers from burnout and work disengagement. Research suggests particular stress mindsets (beliefs about the nature of the stress response) may be important for physical and psychological wellbeing and performance. The current project investigated if relationships existed between officer perceptions of psychosocial safety climate, burnout and work engagement. The Griffith University research team investigated the protective role of stress mindsets in those relationships. This project provides practical insight into the protective role of stress mindsets and discusses the potential these findings have in protecting officers from the outcomes of burnout and work disengagement.

description: Abstract – The wireless arena has been experiencing exponential growth in the last couple of years. In twenty- first century, due to recent advances in sensor and wireless communication technologies have enabled a new generation of massive-scale Wireless sensor network (WSN) and is not-too-distant future when miniature, low-cost sensors may be literally sprayed onto walls, roads, or machines, creating a digital skin that can observe a variety of interested physical phenomena. Due to the severe energy constraint of a sensor node, network architectures and protocol are important aspects in the design of Wireless sensor network due to their big impact on the energy consumption. Since last couple of years to prolong the network lifetime of a tiny sensor node various researchers have proposed a number of energy efficient routing protocols. Up till now, their performance superior or worse cannot be inspected without any suspicion by conventional techniques because of their transformed behavior in different environments. The aspire of this research is to evaluate the performance among energy efficient routing protocols in Wireless sensor networks (WSNs) based on metrics Overhead, Delay, Packet Delivery Ratio (PDR) and Congestion over Energy consumption and Network lifetime. The current research work can be utilized to guide protocol designing, application-specific protocol selection and modification of the existing routing protocols in Wireless sensor networks. Simulations between Energy Efficient Cluster based Data Gathering Protocol ECDGP and Energy Efficient Data Collection Protocol-Tree Based EEDCP-TB confirms their results in term of Overhead, Delay, Packet Delivery Ratio (PDR) and Congestion on Energy consumption and Network lifetime.

description: Das Ziel dieser Arbeit ist die Analyse und Entwicklung einer Aktor-Bibliothek in Rust. Existierende Aktor-Bibliotheken in Rust verletzen grundlegende Regeln des Aktor-Modells, wodurch diese in nicht allen Anwendungsfällen verwendet werden können. Des Weiteren existiert keine strukturierte Arbeit zu der Entwicklung einer Aktor-Bibliothek in Rust. Die in dieser Arbeit entwickelte Bibliothek entspricht einerseits den Ideen des Aktor-Modells, andererseits wird die Erarbeitung und die durchlaufene Analyse der Bibliothek durch diese Arbeit dokumentiert. In einem ersten Schritt wird das Aktor-Modell und grundlegende Spracheigenschaften von Rust eingeführt, bevor das Design der entwickelten Aktor-Bibliothek vorgestellt und getroffene Design-Entscheidungen beschrieben und begründet werden. Darauffolgend werden die Implementationen der relevantesten Komponenten der Bibliothek beschrieben und anhand von Code-Beispielen erklärt. Des Weiteren wird das Design und die Implementation eines Test-Frameworks für Aktoren präsentiert, das das Testen von Aktoren erleichtern soll. Anhand der Implementation eines Praxisbeispiels wird die entwickelte Aktor-Bibliothek mit Java Akka durch Code-Vergleiche und Benchmarks verglichen. Hierbei wird gezeigt, dass die Verwendung der entwickelten Bibliothek mit einem vergleichbar gleich großen Code-Aufwand zu denselben und mitunter besseren Ergebnissen führen kann. Abschließend werden vorhandene Einschränkungen der entwickelten Bibliothek und deren Auswirkungen beschrieben.

description: We provide a quantum algorithm for simulating the dynamics of sparse Hamiltonians with complexity sublogarithmic in the inverse error, an exponential improvement over previous methods. Specifically, we show that a $d$-sparse Hamiltonian $H$ acting on $n$ qubits can be simulated for time $t$ with precision $ε$ using $O\big(τ\frac{\log(τ/ε)}{\log\log(τ/ε)}\big)$ queries and $O\big(τ\frac{\log^2(τ/ε)}{\log\log(τ/ε)}n\big)$ additional 2-qubit gates, where $τ= d^2 \|{H}\|_{\max} t$. Unlike previous approaches based on product formulas, the query complexity is independent of the number of qubits acted on, and for time-varying Hamiltonians, the gate complexity is logarithmic in the norm of the derivative of the Hamiltonian. Our algorithm is based on a significantly improved simulation of the continuous- and fractional-query models using discrete quantum queries, showing that the former models are not much more powerful than the discrete model even for very small error. We also simplify the analysis of this conversion, avoiding the need for a complex fault correction procedure. Our simplification relies on a new form of "oblivious amplitude amplification" that can be applied even though the reflection about the input state is unavailable. Finally, we prove new lower bounds showing that our algorithms are optimal as a function of the error.

Leading terms of Artin L-series at negative integers and annihilation of higher K-groups
Creators: name: Nickel, Andreas
Publisher: name: Universität Regensburg
Year: 2010
Subjects: subject: 510 Mathematik

description: Let L/K be a finite Galois extension of number fields with Galois group G. We use leading terms of Artin L-series at strictly negative integers to construct elements which we conjecture to lie in the annihilator ideal associated to the Galois action on the higher dimensional algebraic K-groups of the ring of integers in L. For abelian G our conjecture coincides with a conjecture of Snaith and thus generalizes also the well known Coates-Sinnott conjecture. We show that our conjecture is implied by the appropriate special case of the equivariant Tamagawa number conjecture (ETNC) provided that the Quillen-Lichtenbaum conjecture holds. Moreover, we prove induction results for the ETNC in the case of Tate motives h0(Spec(L))(r), where r is a strictly negative integer. In particular, this implies the ETNC for the pair (h0(Spec(L))(r),M), where L is totally real, r < 0 is odd and M is a maximal order containing Z[ 1/2 ]G, and will also provide some evidence for our conjecture.

description: Let $H$ be a Krull monoid with finite class group $G$. Then every non-unit $a \in H$ can be written as a finite product of atoms, say $a=u_1 \cdot \ldots \cdot u_k$. The set $\mathsf L (a)$ of all possible factorization lengths $k$ is called the set of lengths of $a$. If $G$ is finite, then there is a constant $M \in \mathbb N$ such that all sets of lengths are almost arithmetical multiprogressions with bound $M$ and with difference $d \in Δ^* (H)$, where $Δ^* (H)$ denotes the set of minimal distances of $H$. We show that $\max Δ^* (H) \le \max \{\exp (G)-2, \mathsf r (G)-1\}$ and that equality holds if every class of $G$ contains a prime divisor, which holds true for holomorphy rings in global fields.

description: Within the framework of the unrestricted time-dependent density functional theory, we present for the first time an analysis of the relativistic Coulomb excitation of the heavy deformed open shell nucleus $^{238}$U. The approach is based on Superfluid Local Density Approximation (SLDA) formulated on a spatial lattice that can take into account coupling to the continuum, enabling self-consistent studies of superfluid dynamics of any nuclear shape. We have computed the energy deposited in the target nucleus as a function of the impact parameter, finding it to be significantly larger than the estimate using the Goldhaber-Teller model. The isovector giant dipole resonance, the dipole pygmy resonance and giant quadrupole modes were excited during the process. The one body dissipation of collective dipole modes is shown to lead a damping width $Γ_\downarrow \approx 0.4$ MeV and the number of pre-equilibrium neutrons emitted has been quantified.

description: Der Begriff Digital Rights Management (DRM) umfasst Richtlinien, Techniken und digitale Werkzeuge, mit denen die Nutzung digitaler Inhalte eingeschränkt, gesteuert und kontrolliert werden kann. Im Wesentlichen werden dabei Technologien von Rechteinhaber:innen zur Zugangs- und Nutzungssteuerung sowie Verfolgung von Rechtsverstößen und gegebenenfalls sogar zur differenzierten Abrechnung digitaler Inhalte angewendet. Herkömmliche DRM-Systeme bestehen hauptsächlich aus Software und stützen sich auf softwarebasierte IT-Sicherheit. Um die IT-Sicherheit von DRM-Systeme auszuweiten, können Hardwarekomponenten eingesetzt werden. Die Kombination aus software- und hardwarebasierter IT-Sicherheit wird als Trusted Computing (TC) bezeichnet und ermöglicht Rechteinhaber:innen völlig neue Szenarien. Um die Möglichkeiten von DRM mit TC zu erforschen bzw. diese zu demonstrieren, wurde im praktischen Teil dieser Arbeit eine technische und organisatorische Maßnahme prototypisch umgesetzt, mit der es einem Auftraggeber-System möglich ist, mit einer definierten Lizenz (bzw. DRM-Policy) sensible proprietäre Daten an ein Auftragnehmer-System zu senden, sodass dieses die sensiblen Daten nur auf eine Art und Weise verwenden kann, wie die Lizenz es vorgibt. Zur Umsetzung der Systeme wurde ein kryptografischer Coprozessor - genannt Trusted Platform Module (TPM) - verwendet. Das TPM verfügt über weitreichende kryptografische Funktionalitäten und bietet eine hardwarebasierte IT-Sicherheit. Das Gesamtsystem wurde somit als zweiteiliges System, ein Auftraggeber-System und ein Auftragnehmer-System, umgesetzt. Im theoretischen Teil der Arbeit wird zuerst auf DRM und anschließend auf TC eingegangen. Besonders einige wichtige Funktionalitäten des TPM, welche in das System integriert wurden, werden erläutert. Des Weiteren wird auch das abhörsichere Kommunikationsprotokoll Hypertext Transfer Protocol Secure (HTTPS) vorgestellt und erklärt. HTTPS wird verwendet für den geschützten Datenaustausch zwischen den beiden Teilsystemen. Wie das Gesamtsystem inklusive der beiden Teilsystemen umgesetzt wurde, sowie welche Features es bietet und wie es funktioniert wird auch in einem Kapitel präsentiert und erläutert. Abschließend werden die positiven und negativen Aspekte des Systems sowie eine auf eigener Meinung beruhende Schlussfolgerung präsentiert.

Spin-orbit coupling and anisotropic exchange in two-electron double quantum dots

Publisher: name: Universität Regensburg

Subjects: subject: 530 Physik

description: The influence of the spin-orbit interactions on the energy spectrum of two-electron laterally coupled quantum dots is investigated. The effective Hamiltonian for a spin qubit pair proposed in Baruffa et al. [Phys. Rev. Lett. 104, 126401 (2010)] is confronted with exact numerical results in single and double quantum dots in zero and finite magnetic field. The anisotropic exchange Hamiltonian is found quantitatively reliable in double dots in general. There are two findings of particular practical importance: (i) the model stays valid even for maximal possible interdot coupling (a single dot), due to the absence of a coupling to the nearest excited level, a fact following from the dot symmetry. (ii) In a weak-coupling regime, the Heitler-London approximation gives quantitatively correct anisotropic exchange parameters even in a finite magnetic field, although this method is known to fail for the isotropic exchange. The small discrepancy between the analytical model (which employs the linear Dresselhaus and Bychkov-Rashba spin-orbit terms) and the numerical data for GaAs quantum dots is found to be mostly due to the cubic Dresselhaus term.

Using the data from XMM-Newton, we located the short bursts by Bayesian blocks algorithm. The short bursts' duration distributions for three sources were fitted by two lognormal functions. The spectra of shorter bursts ($< 0.2~\rm s$) and longer bursts ($\geq 0.2~\rm s$) can be well fitted in two blackbody components model or optically thin thermal bremsstrahlung model for SGR 0501+4516. We also found that there is a positive correlation between the burst luminosity and the persistent luminosity with a power law index $γ= 1.23 \pm 0.18 $. The energy ratio of this persistent emission to the time averaged short bursts is in the range of $10 - 10^3$, being comparable to the case in Type I X-ray burst.

description: For the past twelve years, cold plasmas (i.e., weakly ionized gas) have been positioned as a breakthrough technology for treating cancer thanks to their antitumor properties. The innovation of ad hoc plasma sources and personalized protocols appears crucial to treat cancers with a very poor prognosis. This is the case for cholangiocarcinoma (CCA), a biliary tract cancer, whose treatment with cold plasma is envisioned but requires the innovation of catheters and endoscopic devices for local therapies. Before conducting clinical trials, the performances and limitations of cold plasma endoscopy must be evaluated in terms of safety for both the patient and clinician as well as in terms of therapeutic efficacy. These objectives are pursued in the present work, in which a transferred plasma catheter is used, powered by 8-10 kV, 1-2 μs wide, 5-10 kHz repeated pulses, allowing guided streamers to be transferred over lengths of at least 2 m. In a first step, the catheter is utilized without the duodenoscope and directly inserted into an artificial model reproducing the topography and the electrical response of the biliary tree. This model allows to validate the technical feasibility of the technology and to demonstrate the absence of electrical and thermal risks. Indeed, the voltage and current deposited are as low as 3.98 V and 1.19 mA (RMS values) respectively, while the temperature locally increases from 23°C to 27 °C. In a second step, the catheter is inserted into the duodenoscope, the whole being applied to a porcine anatomical model. After passing through the esophagus, stomach and duodenum, the distal part of the duodenoscope is placed at the entrance to the papilla so that the catheter can easily enter the choledoc and then the common bile duct. Interestingly, the electrical power values deposited are of the order of 100 mW especially because the current values are at least 10 times higher. These more elevated values of electrical parameters but also electromagnetic effects are discussed considering physical aspects like eddy currents. The absence of electrical and thermal risks is demonstrated and consolidated by the IEC standards for medical devices. In a third time, we demonstrate that the cold plasma catheter can induce antitumor effects on in vitro experimental models of human CCA. The methodology proposed in this article validates the relevance of cold plasma endoscopy as a potential local treatment for cholangiocarcinoma and allows bridging cognitive and patient-oriented research.

description: Two process tracing studies investigated how the information acquisition process in a binary choice task is influenced by the overall level of attractiveness of alternatives, by the magnitude of differences in attractiveness of alternatives, and by the dominance of one alternative. All three factors influenced the subjects’ information selection process regarding the multiattribute choice alternatives. Subjects selected more information when the attractiveness difference was small and when one of the alternatives was not dominant. Moreover, they considered more information when the choice alternatives were both unattractive. These findings were obtained when information was presented about the alternatives both numerically and nonnumerically. The experimental results were explained within a sequential sampling strategy framework.

We show that, in general, these states mix with repercussions on the electroweak physics and phenomenology. Our results will help clarify the main differences, similarities, benefits and shortcomings of the different ways one can naturally realize a composite nature of the electroweak sector of the Standard Model. We will analyze the minimal underlying realization in terms of fundamental strongly coupled gauge theories supporting the flavor symmetry breaking pattern SU(4)/Sp(4) $\sim$ SO(6)/SO(5). The most minimal fundamental description consists of an SU(2) gauge theory with two Dirac fermions transforming according to the fundamental representation of the gauge group. This minimal choice enables us to use recent first principle lattice results to make the first predictions for the massive spectrum for models of composite (Goldstone) Higgs dynamics. These results are of the upmost relevance to guide searches of new physics at the Large Hadron Collider.

description: As part of applications dealing with cardiovascular tissue engineering, drop-cast polyvinylidene fluoride (PVDF) scaffolds have been treated by cold plasma to enhance their adherence to cardiac cells. The scaffolds were treated in a dielectric barrier device where cold plasma was generated in a gaseous environment combining a carrier gas (helium or argon) with/without a reactive gas (molecular nitrogen). We show that an Ar-N2 plasma treatment of 10 min results in significant hydrophilization of the scaffolds, with contact angles as low as 52.4° instead of 132.2° for native PVDF scaffolds. Correlation between optical emission spectroscopy and X-ray photoelectron spectroscopy shows that OH radicals from the plasma phase can functionalize the surface scaffolds, resulting in improved wettability. For all plasma-treated PVDF scaffolds, the adhesion and maturation of primary cardiomyocytes is increased, showing a well-organized sarcomeric structure (α-actinin immunostaining). The efficacy of plasma treatment was also supported by real-time PCR analysis to demonstrate an increased expression of the genes related to adhesion and cardiomyocyte function. Finally, the biocompatibility of the PVDF scaffolds was studied in a cardiac environment, after implantation of acellular scaffolds on the surface of the heart of healthy mice. Seven and 28 days after implantation, no exuberant fibrosis and no multinucleated giant cells were visible in the grafted area, hence demonstrating the absence of foreign body reaction and the biocompatibility of these scaffolds.

description: We consider inverse curvature flows in the $(n+1)$-dimensional Euclidean space, $n\geq 2,$ expanding by arbitrary negative powers of a 1-homogeneous, monotone curvature function $F$ with some concavity properties. We obtain asymptotical roundness, meaning that circumradius minus inradius of the flow hypersurfaces decays to zero and that the flow becomes close to a flow of spheres.

description: Coffee husk considers as one of the agricultural waste lignocellulosic biomass that contain high

amount of cellulose. Furthermore, the aim of this work was, valorization of coffee husks to

bioethanol by using separate hydrolysis and fermentation methods which is critically used as

replacements for renewable sources of energy and to minimize environmental pollutions too.

This method was accomplished by four major experimental procedures, which were

pretreatment, hydrolysis, fermentation and distillation processes. There were three parameters

and 20 lab experiments exposed in the laboratory work depending on the H2SO4 concentration,

hydrolysis temperature and time in the hydrolysis step. The effect of these parameters was

analyzed using design expert soft war by CCD design. The results were show that the content

of sugars increased as the acid (H2SO4) concentration increased from 1% - 3 % and decreased

as the acid concentrations increased from 3 % up to 5%. At the optimal acid concentration (3%;

H2SO4), hydrolysis temperature (130 ℃) and hydrolysis time (70min), the sugar yield gotten

was 46.75% from the coffee husk. This sample was further investigated to produce bioethanol

and the ethanol yield from this experiment was 51.03%. Based on central composite design

ANOVA was carried out to determine the numerical significance of the quadratic response

surface model, in which the p-value of the model was less than 0.0001, which shows the model

was statistically significant. Consequently, based on this result, the designated model was

adequate to fit the data of response variable

Transmission and multiple reflection mechanisms of guided streamers propagating through grounded annular electrode and interacting with grounded surface electrode

description: The repeatable dynamics and the reversal propagation of guided streamers remains a major question of fundamental physics. In this article, trains of positive guided streamers are generated within an atmospheric pressure plasma jet supplied in helium and polarized by a high-voltage nanosecond pulse generator. The device is completed by two distant targets: a grounded annular electrode coaxially centered around the capillary through which guided streamers can propagate, and a grounded surface electrode on which they can interact. The resulting transmitted and multiple reflected guided streamers are measured combining optical characterization (fast ICCD imaging) and electrical characterization (high voltage probe and current monitors). While the electrical approach provides information on the capacitive/conductive nature of the current peaks as well as on their positive/negative value, fast ICCD imaging distinguishes whether the guided streamers are incident, reflected or transmitted. Combining these two techniques allow us to demonstrate experimentally that the reflected streamers are negative contrarily to the others. Besides, 4 types of reflections have been highlighted: a reflection (r) at the outlet of the capillary, a reflection on the grounded surface electrode (R) and two reflections (r’ and r”) observed when an incident guided streamer passes through the grounded annular electrode. The two techniques agree that the characteristic propagation times are always shorter for reflected negative streamers than for the positive ones propagating forward. Hence, for a grounded annular electrode placed 3 cm away from the high voltage electrode, propagation time is 80 ns for reflection versus 250 ns for transmission. These characteristic propagation times are even shorter when the annular electrode is brought closer to the surface electrode with velocities typically higher than 300 km/s. In addition, the intensity ratios of reflected/incident guided currents drop sharply, typically losing one decade over a counter-propagation length of only 3-5 cm. Finally, all these experimental data are utilized to build an equivalent electrical model that allow to better understand the dynamics of the guided streamers and explain their transmission and reflection modes upon their interaction with the two distant grounded electrodes.
A reanalysis of a strong-flow gyrokinetic formalism

description: We reanalyse an arbitrary-wavelength gyrokinetic formalism [A. M. Dimits, Phys. Plasmas $\bf17$, 055901 (2010)], which orders only the vorticity to be small and allows strong, time-varying flows on medium and long wavelengths. We obtain a simpler gyrocentre Lagrangian up to second order. In addition, the gyrokinetic Poisson equation, derived either via variation of the system Lagrangian or explicit density calculation, is consistent with that of the weak-flow gyrokinetic formalism [T. S. Hahm, Phys. Fluids $\bf31$, 2670 (1988)] at all wavelengths in the weak flow limit. The reanalysed formalism has been numerically implemented as a particle-in-cell code. An iterative scheme is described which allows for numerical solution of this system of equations, given the implicit dependence of the Euler-Lagrange equations on the time derivative of the potential.

description: An exploration environment and tutoring strategies were developed for the first few hours of learning the programming language LISP. In this environment, the amount of exploratory and receptive learning can be systematically manipulated. In an experimental study with three different learning conditions, learning in a basic exploration environment (without an automated tutor) was compared to learning with an automated tutor that provided help rather selectively, and with an automated tutor that provided help whenever possible. The results showed that the selective tutor condition was most effective: The students in this condition took the least time in acquiring knowledge and solving the criterion test tasks, while solving equal numbers ofthe tasks correctly.
