description: We present the largest sample of high-mass star-forming regions observed using submillimetre imaging polarimetry. The data were taken using SCUBA in conjunction with the polarimeter on the JCMT in Hawaii. In total, 16 star forming regions were observed, although some of these contain multiple cores. The polarimetry implies a variety of magnetic field morphologies, with some very ordered fields. We see a decrease in polarisation percentage for 7 of the cores. The magnetic field strengths estimated for 14 of the cores, using the corrected CF method, range from <0.1 mG to almost 6 mG. These magnetic fields are weaker on these large scales when compared to previous Zeeman measurements from maser emission, implying the role of the magnetic field in star formation increases in importance on smaller scales. Analysis of the alignment of the mean field direction and the outflow directions reveal no relation for the whole sample, although direct comparison of the polarimetry maps suggests good alignment (to at least one outflow direction per source) in 7 out of the 15 sources with outflows.

description: Data-driven machine-learning for predicting instantaneous and future fault-slip in laboratory experiments has recently progressed markedly due to large training data sets. In Earth however, earthquake interevent times range from 10's-100's of years and geophysical data typically exist for only a portion of an earthquake cycle. Sparse data presents a serious challenge to training machine learning models. Here we describe a transfer learning approach using numerical simulations to train a convolutional encoder-decoder that predicts fault-slip behavior in laboratory experiments. The model learns a mapping between acoustic emission histories and fault-slip from numerical simulations, and generalizes to produce accurate results using laboratory data. Notably slip-predictions markedly improve using the simulation-data trained-model and training the latent space using a portion of a single laboratory earthquake-cycle. The transfer learning results elucidate the potential of using models trained on numerical simulations and fine-tuned with small geophysical data sets for potential applications to faults in Earth.

Colloidal two-dimensional metal chalcogenides: Realization and application of the structural anisotropy

description: Due to the spatial confinement, two-dimensional metal chalcogenides display an extraordinary optical re-sponse and carrier transport ability. Solution-based synthesis techniques such as colloidal hot injection and ion exchange provide a cost-effective way to fabricate such low-dimensional semiconducting nanocrystals. Over the years, developments in colloidal chemistry made it possible to synthesize various kinds of ultrathin colloidal nanoplatelets, including wurtzite- and zinc blende-type CdSe, rocksalt PbS, black phosphorus-like SnX (X=S or Se), hexagonal copper sulfides, selenides and even transition metal dichalcogenides (TMD) like MoS2. By altering experimental conditions and applying capping ligands with specific functional groups, it is possible to accurately tune the dimensionality, geometry and consequently the optical prop-erties of these colloidal metal chalcogenide crystals. Here, we review recent progresses in the syntheses of two-dimensional colloidal metal chalcogenides (CMCs) and property characterizations based on optical spectroscopy or device-related meas-urements. The discoveries shine a light on their huge prospect for applications in areas such as photovoltaics, optoelectronics and spintronics. In specific, the formation mechanisms of two-dimensional CMCs are discussed. The growth of colloidal nano-crystals into a two-dimensional shape is found to require either an intrinsic structural asymmetry or the assist of coexisted ligand molecules, which act as lamellar double-layer templates or "facet" the crystals via selective adsorption. By performing optical characterizations and especially ultrafast spectroscopic measurements on these two-dimensional CMCs, their unique electronic and excitonic features are revealed.

Generation mechanism of terahertz coherent acoustic phonons in Fe

Publisher: name: My University
Year: 2016
Subjects: cond-mat.mtrl-sci

description: © 2016 American Physical Society. We use femtosecond time-resolved hard x-ray scattering to detect coherent acoustic phonons generated during ultrafast laser excitation of ferromagnetic bcc Fe films grown on MgO(001). We observe the coherent longitudinal-acoustic phonons as a function of wave vector through analysis of the temporal oscillations in the x-ray scattering signal. The width of the extracted strain wave front associated with this coherent motion is ∼100 fs. An effective electronic Grüneisen parameter is extracted within a two-temperature model. However, ab initio calculations show that the phonons are nonthermal on the time scale of the experiment, which calls into question the validity of extracting physical constants by fitting such a two-temperature model.

description: We present a picture of star formation around the HII region Sh2-235 (S235) based upon data on the spatial distribution of young stellar clusters and the distribution and kinematics of molecular gas around S235. We observed 13CO(1-0) and CS(2-1) emission toward S235 with the Onsala Space Observatory 20-m telescope and analysed the star density distribution with archival data from the 2MASS survey. Dense molecular gas forms a shell-like structure at the south-eastern part of S235. The young clusters found with 2MASS data are embedded in this shell. The positional relationship of the clusters, the molecular shell and the HII region indicates that expansion of S235 is responsible for the formation of the clusters. The gas distribution in the S235 molecular complex is clumpy, which hampers interpretation exclusively on the basis of the morphology of the star forming region. We use data on kinematics of molecular gas to support the hypothesis of induced star formation, and distinguish three basic types of molecular gas components. The first type is primordial undisturbed gas of the giant molecular cloud, the second type is gas entrained in motion by expansion of the HII region (this is where the embedded clusters were formed), and the third type is a fast-moving gas, which might have been accelerated by winds from the newly formed clusters. The clumpy distribution of molecular gas and its kinematics around the HII region implies that the picture of triggered star formation around S235 can be a mixture of at least two possibilities: the "collect-and-collapse" scenario and the compression of pre-existing dense clumps by the shock wave.

description: The evolving landscape of financial markets demands the integration of advanced technologies and quantamental paradigms like market simulations and artificial intelligence. This study explores the use of agent-based interactive discrete event trading simulations to analyze financial market scenarios and detect anomalies. The research involves various market fees and synthetic competition between exchanges, utilizing an inter-market spread arbitrage machine for price stability. This approach enables the observation of anomalies related to spreads, execution speed, traded volumes, liquidity, order execution probability, and agent decision-making influence. This study could serve as a valuable tool for financial institutions and regulatory authorities in strategic decision-making concerning financial market challenges.

description: © 2016 American Physical Society. We image local structural rearrangements in soft colloidal glasses under small periodic perturbations induced by thermal cycling. Local structural entropy S2 positively correlates with observed rearrangements in colloidal glasses. The high S2 values of the rearranging clusters in glasses indicate that fragile regions in glasses are structurally less correlated, similar to structural defects in crystalline solids. Slow-evolving high S2 spots are capable of predicting local rearrangements long before the relaxations occur, while fluctuation-created high S2 spots best correlate with local deformations right before the rearrangement events. Local free volumes are also found to correlate with particle rearrangements at extreme values, although the ability to identify relaxation sites is substantially lower than S2. Our experiments provide an efficient structural identifier for the fragile regions in glasses and highlight the important role of structural correlations in the physics of glasses.

Subjects: subject: AI Systems

description: The rapid advancement of Artificial Intelligence (AI) technologies has sparked a discussion within organisations, questioning whether regulatory frameworks like the European Artificial Intelligence Act (EU AI Act) pose obstacles or opportunities for innovation and growth. In response to this ongoing discourse, this paper introduces a comprehensive lifecycle model tailored for high-risk AI systems. On the basis of a literature review, state-of-the-art Machine Learning (ML)/AI and software development lifecycles were identified to establish a foundational framework. By examining the requirements of the AI Act, specific to high-risk AI systems, actionable steps were extracted and integrated into the lifecycle. The resulting framework was developed iteratively, incorporating adaptations from identified lifecycles and mapping essential compliance steps. Expert interviews provided valuable insights for refinement, leading to a universal and future-proof lifecycle. The proposed framework not only ensures compliance with regulatory standards but also fosters innovation and development in the AI landscape.

description: We present results of the investigation of the giant radio pulses (GRPs) generation rate from 5 radio pulsars (B0301+19, B0950+08, B1112+50, B1133+16, and B1237+25) and anomalous intensity pulses generation rate from B0809+74. All data used were obtained with Large Phased Array radio telescope of Pushchino Radio Astronomy Observatory at 111~MHz from 2012 to 2021. In addition to analysis of the rate of generation of bright pulses, we analyze the distribution of bright pulses in the phase of the pulsar period and search for clusters of bright pulses - several bright pulses emit in adjacent pulsar periods. It is found that pulsars B0301+19, B1112+50, B1133+16, and B1237+25 demonstrate different generation rates and generation of clusters. Pulsar B1112+50 more often than others studied pulsars generates GRPs cluster. The longest cluster of GRPs containing four single pulses is detected from this pulsar. GRPs from studied pulsars are distributed along the longitudes of the main components of average pulses of these pulsars. This distribution is 1.5-2 times narrower than the phase distribution of non-giant pulses. It is found that the distance between the components of the average GRP profile and the distance between the components of the average non-giant profile differ substantially for pulsars with multicomponent average profiles.

description: Adsorption of hydrogen atoms on a single graphite sheet (graphene) has been investigated by first-principles electronic structure means, employing plane-wave based, periodic density functional theory. A reasonably large 5x5 surface unit cell has been employed to study single and multiple adsorption of H atoms. Binding and barrier energies for sequential sticking have been computed for a number of configurations involving adsorption on top of carbon atoms. We find that binding energies per atom range from ~0.8 eV to ~1.9 eV, with barriers to sticking in the range 0.0-0.2 eV. In addition, depending on the number and location of adsorbed hydrogen atoms, we find that magnetic structures may form in which spin density localizes on a $\sqrt{3}{x}\sqrt{3}{R}30^{\circ}$ sublattice, and that binding (barrier) energies for sequential adsorption increase (decrease) linearly with the site-integrated magnetization. These results can be rationalized with the help of the valence-bond resonance theory of planar $π$ conjugated systems, and suggest that preferential sticking due to barrierless adsorption is limited to formation of hydrogen pairs.

description: Wenngleich eine allgemeine Definition des Begriffs Krankheit nicht gelingt, so ist vielen Krankheitsbildern gemeinsam, dass Betroffene objektiv Einschränkungen hinsichtlich ihres Wohlbefindens wahrnehmen und Bereitschaft zeigen, diesen entgegen zu wirken. Nicht nur bei zivilisationsbedingten Erkrankungen, sondern im Zusammenhang mit einer Großzahl chronischer Erkrankungen, werden Bewegung und Sport sowohl zur Prophylaxe wie auch als wesentliche Therapieunterstützung angesehen. Dies betrifft bspw. Herz-Kreislauferkrankungen, Diabetes, Osteoporose sowie neurologische Erkrankungen, zu denen Parkinson als zweithäufigste neurodegenerative Erkrankung zählt. In Deutschland sind ca. 200.000 Menschen von Parkinson betroffen, verbunden mit einer deutlichen, maßgeblich demografisch verursachten jährlichen Steigerung. Bewegungstherapuetischen Maßnahmen, wie sie häufig verordnet werden, steht der Mensch entgegen: Trägheit, Verzweiflung, Resignation, offensichtliche Ausweglosigkeit sind nur einige Motive, die dazu führen, dass nach einem initalen Aufbruch das eigenständige Festhalten an regelmäßiger Bewegung ausbleibt und damit unweigerlich die Spirale der gefühlten und nachweisbaren Verschlechterung des Gesundheitszustands in Gang gebracht wird. Die hier vorgestellte Anwendung ist für das Zielkrankheitsbild Parkinson entwickelt. Den Erkrankten werden kontinuierlich Motivationsimpulse, sich zu bewegen, mittels kurzweiliger Videosequenzen gegeben. Die Videos wurden von dem selbst an Parkinson erkranktem Schauspieler und Komiker Markus Maria Profitlich und der Diplomsportlehrerin sowie Gymnastik- und Tanzpädagogin Ingrid Profitlich in Szene gesetzt. Erweitert ist die Anwendung mittels eines völlig neuartigen, universellen und gleichermaßen einfachen Spiels, um zusätzliche Anreize zum Ausführen der Bewegungsübungen zu schaffen. Die Applikation ist seit Oktober 2022 auf der Plattform App Store (Apple) und seit Mai 2023 auf der Plattform Google Play frei verfügbar.

description: © 2014 ACM. We present a simple method to solve spherical harmonics moment systems, such as the the time-dependent PN and SPN equations, of radiative transfer. Themethod, which works for arbitrary moment order N, makes use of the specific coupling between the moments in the PN equations. This coupling naturally induces staggered grids in space and time, which in turn give rise to a canonical, second-order accurate finite difference scheme. While the scheme does not possess TVD or realizability limiters, its simplicity allows for a very efficient implementation in MATLAB. We present several test cases, some of which demonstrate that the code solves problems with ten million degrees of freedom in space, angle, and time within a few seconds. The code for the numerical scheme, called StaRMAP (Staggered grid Radiation Moment Approximation), along with files for all presented test cases, can be downloaded so that all results can be reproduced by the reader.

description: We investigate boundary dynamics of orbifold conformal field theory involving T-duality twists. Such models typically appear in contexts of non-geometric string compactifications that are called monodrofolds or T-folds in recent literature. We use the framework of boundary conformal field theory to analyse the models from a microscopic world-sheet perspective. In these backgrounds there are two kinds of D-branes that are analogous to bulk and fractional branes in standard orbifold models. The bulk D-branes in T-folds allow intuitive geometrical interpretations and are consistent with the classical analysis based on the doubled torus formalism. The fractional branes, on the other hand, are `non-geometric' at any point in the moduli space and their geometric counterparts seem to be missing in the doubled torus analysis. We compute cylinder amplitudes between the bulk and fractional branes, and find that the lightest modes of the open string spectra show intriguing non-linear dependence on the moduli (location of the brane or value of the Wilson line), suggesting that the physics of T-folds, when D-branes are involved, could deviate from geometric backgrounds even at low energies. We also extend our analysis to the models with SU(2) WZW fibre at arbitrary levels.

description: A major impediment in treating substance use disorder (SUD) is craving following exposure to drug-associated environmental cues. Exposure to a cocaine-predictive context can trigger the retrieval of cocaine-associated memories. When cocaine-associated memories are recalled, they become unstable and need to be reconsolidated to persist. Memory reconsolidation is dependent on several mechanisms, including de novo protein synthesis and synaptic plasticity. Manipulations that disrupt unstable cocaine memories or impede their reconsolidation have been shown to reduce drug-seeking behavior; however, little is known about the mechanisms regulating drug memory strength. Therefore, understanding the neurobiological mechanisms of drug memory maintenance remains of great importance, with the long-term goal of identifying treatment approaches to prevent cocaine relapse. To that end, this thesis evaluated the roles of 2-arachidonoglycerol (2-AG) and anandamide (AEA) in contextual drug-memory reconsolidation using an instrumental model of context-induced cocaine relapse. The 2-AG and AEA systems were probed by enzyme inhibitor manipulations that targeted 2-AG or AEA synthesis or

Chapter Two outlines the design and methodology of the experiments in this study. Chapter Three describes the behavioral effects of enzyme inhibitor manipulation. Chapter Four includes a summary of the findings and discusses their significance in the context of the literature on memory reconsolidation. Overall, this thesis provides evidence in support of the argument that 2-AG, but not AEA, signaling in the BLA regulates contextual cocaine-associated memory strength. This outcome suggests that 2-AG may be a viable therapeutic target for relapse prevention in individuals with cocaine use disorder.

description: This scoping review examines the breadth of literature on intervention approaches targeting health disparities associated with allostatic load. The allostatic load framework provides a foundation for understanding the impact of chronic stress on health outcomes and disparities. While aspects of the framework have been well studied, targeted approaches to addressing health disparities remain under-explored.The review includes selected studies from both high-income countries (HICs) and low/middle-income countries (LMICs) to illustrate meaningful interventions in different settings. Carroll et al.’s U.S.-based study demonstrated allostatic load reduction through Cognitive Behavioral Therapy and Tai Chi Chih, while Zeng Jie Ye et al.’s China-based study explored supportive-expressive group therapy’s impact on psychological and physiological outcomes in metastatic breast cancer patients.The uploaded materials include key articles referenced in the review, covering HIC and LMIC contexts, as well as works cited by the authors. Additionally, the query process deriving these materials are supported the PRISMA flow diagram. Collated materials are referenced in relevant tables supporting the review’s findings.The findings highlight a substantial gap in research on interventions addressing allostatic load-associated health disparities. Future studies should focus on systematic intervention analyses to develop effective strategies for reducing the global burden of disease and mortality linked to allostatic load.

description: Mehrwert-Anwendungen auf Basis intelligenter Messsysteme sollen die Digitalisierung der Energiewende akzeptanzbasiert vorantreiben. Als Mehrwert-Anwendungen können im privaten Elektrizitätssektor nicht-energiewirtschaftlich relevante Zusatz-Leistungen verstanden werden, die eine weitere Systemkomponente in der Infrastruktur des intelligenten Messsystems erfordern. Ein Beispiel hierfür liefert das optionale Energiemanagement. In dieser Arbeit wird zunächst die Methodik der „Segmentalen Geschäftsmodell-Evaluation“ (SGME) vorgestellt. Anschließend wird diese auf die Evaluation von Mehrwert-Anwendungen angewendet. Als Ergebnis zeigt sich für die Mehrwert-Anwendung „Energiemanagement“, dass von allen betrachteten Kundensegmenten vor allem Prosumer mit Wärmepumpe und ohne Batteriespeicher mögliche Zielkunden sind, aber auch Haushalte mit Wärmepumpe ohne Erzeugungs- und Speichertechnologien relevant sind. Das über alle betrachteten Kundensegmente dieser Mehrwert-Anwendung ermittelte Marktpotenzial von 329 Mio. €/a dürfte durch die Verbreitung von Wärmepumpen zunehmen. Die Nachrüstung bestehender PV-Anlagen mit Batteriespeichern würde sich hemmend auf das Marktpotenzial auswirken, da sich hierdurch der durch die Mehrwert-Anwendung „Energiemanagement“ erzielbare monetäre Kundennutzen reduziert.

We report on high statistics in-beam spectroscopy of $^{32}$Mg with a unique approach, in that two direct reaction probes with different sensitivities to the underlying nuclear structure are employed at the same time. More specifically, states in $^{32}$Mg were populated by knockout reactions starting from $^{33}$Mg and $^{34}$Si, lying inside and outside the island of inversion, respectively. The momentum distributions of the reaction residues and the cross sections leading to the individual final states were confronted with eikonal-based reaction calculations, yielding a significantly updated level scheme for $^{32}$Mg and spin-parity assignments. By fully exploiting observables obtained in this measurement, a variety of structures coexisting in 32Mg was unraveled. Comparisons with theoretical predictions based on shell-model overlaps allowed for clear discrimination between different structural models, revealing that the complete theoretical description of this key nucleus is yet to be achieved.

description: © 2016 American Physical Society. The demonstration of strong and ultrastrong coupling regimes of cavity QED with polyatomic molecules has opened new routes to control chemical dynamics at the nanoscale. We show that strong resonant coupling of a cavity field with an electronic transition can effectively decouple collective electronic and nuclear degrees of freedom in a disordered molecular ensemble, even for molecules with high-frequency quantum vibrational modes having strong electron-vibration interactions. This type of polaron decoupling can be used to control chemical reactions. We show that the rate of electron transfer reactions in a cavity can be orders of magnitude larger than in free space for a wide class of organic molecular species.

description: A general analytic spherically symmetric solution of the Bogomol'nyi equations is found. It depends on two constants and one arbitrary function on radius and contains the Bogomol'nyi-Prasad-Sommerfield and Singleton solutions as particular cases. Thus all spherically symmetric 't Hooft-Polyakov monopoles with massless scalar field and minimal energy are derived.

description: The national plan on Open Science and the Recognition & Rewards program in the Netherlands are two major driving forces in changes in publication and evaluation culture. How can the CRIS systems support these transitions? A working group is conducting a project to understand what is needed from the CRIS systems to support these changes. The key question is “Which role can or must the CRIS have in an academic world without counting, and with a huge diversity of research outputs.”

description: We study the behavior of solutions of the Helmholtz equation $(- Δ_{disc,h} - E)u_h = f_h$ on a periodic lattice as the mesh size $h$ tends to 0. Projecting to the eigenspace of a characteristic root $λ_h(ξ)$ and using a gauge transformation associated with the Dirac point, we show that the gauge transformed solution $u_h$ converges to that for the equation $(P(D_x) - E)v = g$ for a continuous model on ${\bf R}^d$, where $λ_h(ξ) \to P(ξ)$. For the case of the hexagonal and related lattices, {in a suitable energy region}, it converges to that for the Dirac equation. For the case of the square lattice, triangular lattice, {hexagonal lattice (in another energy region)} and subdivision of a square lattice, one can add a scalar potential, and the solution of the lattice Schr{ö}dinger equation $( - Δ_{disc,h} +V_{disc,h} - E)u_h = f_h$ converges to that of the continuum Schr{ö}dinger equation $(P(D_x) + V(x) -E)u = f$.

description: Peripheral venous blood was drawn from the patients in fasting state using a vasculature containing ethylenediaminetetraacetic acid (EDTA) on the morning of the second day after admission. After the blood was isolated, sampling vessels need to be reversed and mixed gently for 5-10 times to ensure the anticoagulant working, and the plasma would be centrifuged and separated as soon as possible within 30min (or stored in a refrigerator at 4℃ for centrifugation and repackaging within 2h). All blood samples were centrifuged for 10 minutes at 4°C with a centrifugal force of 1500g, then 200ul/case of the supernatant was drawn and placed in numbered EP tubes and frozen at −80°C. Blood samples were collected with no more than 3 days from the time point of stool sampling, only at baseline and every three months thereafter (provided that the patient was in good state and compliance).
BRIDGING THE GAP: INCREASING EVIDENCE-BASED PRACTICE UTILIZATION AMONG EXPERIENCED NURSES
Creators: name: Hall, Sandra Lynne
Publisher: name: Zenodo
Year: 2019

description: Evidence demonstrates that nurse engagement in evidence-based practice (EBP) results in improved patient outcomes and increased nurse satisfaction, yet many health care organizations struggle to support nurse participation in this work. A review of literature demonstrated that major barriers to EBP engagement include lack of time, EBP knowledge, and resources such as online databases, librarian assistance, and mentorship. The purpose of this project is to develop a one-year EBP Fellowship program for experienced nurses at an urban pediatric hospital. A curriculum was developed based on evidence and organizational needs, and program guidelines, outcomes, application, and budget were developed to support program implementation. Outcomes to be measured will include number of completed EBP projects, as well as change over time in EBP knowledge and self-efficacy.

description: We study the biased random walk where at each step of a random walk a "controller" can, with a certain small probability, move the walk to an arbitrary neighbour. This model was introduced by Azar et al. [STOC'1992]; we extend their work to the time dependent setting and consider cover times of this walk. We obtain new bounds on the cover and hitting times. Azar et al. conjectured that the controller can increase the stationary probability of a vertex from $p$ to $p^{1-ε}$; while this conjecture is not true in full generality, we propose a best-possible amended version of this conjecture and confirm it for a broad class of graphs. We also consider the problem of computing an optimal strategy for the controller to minimise the cover time and show that for directed graphs determining the cover time is PSPACE-complete.

description: We present a prescription for consistently constructing non-Fock coherent flavour neutrino states within the framework of the seesaw mechanism, and establish that the physical vacuum of massive neutrinos is a condensate of Standard Model massless neutrino states. The coherent states, involving a finite number of massive states, are derived by constructing their creation operator. Such a construction is the key requirement so that the oscillations of particles indeed occur. We comment on the inherent non-unitarity of the oscillation probability induced by the requirement of coherence.

A CRITICAL ANALYSIS OF IMPREST MANAGEMENT PRACTICES AMONG UNIT HEADS AND SERVICE DELIVERY IN RIVERS STATE UNIVERSITIES
Creators: name: Chinedu, Emmanuel Okoro
Publisher: name: AYDEN JOURNAL
Year: 2024
Subjects: Imprest Management, Unit Heads, Service Delivery

description: The study ascertained how imprest is managed for service delivery among unit heads in Rivers State universities. In order to achieve the purpose of the study, the researcher stated five (5) objectives, posed five (5) research questions and formulated five (5) hypotheses that guided the study. The researcher adopted a descriptive survey design. The population of the study was One Hundred and Sixty (160) Heads of Departments (HODs) and Deans in Rivers State Universities, which are Rivers State University and Ignatius Ajuru University of Education. There was no sampling as all the 160 HODs, Directors and Deans in the Rivers State Universities were used for the study. A self-structured instrument was used for collection of data. The instrument was validated by three (3) experts, two (2) Business Educators and one (1) in Measurement and Evaluation, all in Rivers State University, Port Harcourt. To test for the reliability of the instrument, the instrument was administered to thirteen (13) HODs, Directors and Deans of Business Education from Niger Delta University, Bayelsa State and after an interval of two weeks, the same instrument was administered to the same group. Cronbach Alpha formula was used to determine the internal consistency of the instrument which yielded coefficient scores of 0.76, 0.72, 0.78, 0.81 and 0.69 with an overall coefficient score of 0.75 was obtained. The data collected were analysed using weighted mean and Standard Deviation to answer the research questions while the null hypotheses were tested using z-test statistical tool at a significance level of 0.05. Based on the analysis, it was revealed that unit heads adhere to imprest receipt procedures for service delivery, unit heads adhere to imprest disbursement procedures for service delivery, unit heads adhere to imprest retirement procedures for service delivery in Rivers State Universities. It was therefore, recommended that; University management should always organize enlightenment programme for the Unit Heads to encourage them to keep on adhering to imprest reception procedures. University management should from time to time organize in-service workshop programme for the unit heads to keep on refreshing their memory on imprest disbursement procedures to improve in their duty. University management should always organize workshop programme for the unit heads to encourage them in keeping to imprest retirement procedures which will enable them to improve in their duty.
