description: OBJECTIVE: In light of growing debate over whether and how early life educational experiences alter late-life cognitive trajectories, this study sought to more thoroughly investigate the relationship between educational attainment and rates of late-life cognitive decline in a racially, ethnically, and educationally diverse population. METHOD: Older adults (N = 3,435) in the community-based Washington Heights-Inwood Columbia Aging Project were administered neuropsychological tests of memory, language, visuospatial function, and processing speed at approximate 24-month intervals for up to 18 years. Second-order latent growth curves estimated direct and indirect (through income) effects of educational attainment on rates of global cognitive decline separately in individuals with low (0-8 years) and high (9-20 years) educational attainment. RESULTS: More years of education were associated with higher cognitive level and slower cognitive decline in individuals with low or high educational attainment. The association between having more than 9 years of education and exhibiting slower cognitive decline was fully mediated by income. Although having additional years of education up to 8 years was also associated with higher income, this did not explain associations between education and cognitive change in the low-education group. CONCLUSIONS: Early education (i.e., up to 8 years) may promote aspects of development during a sensitive period of childhood that protect against late-life cognitive decline independent of income. In contrast, later education (i.e., 9 years and beyond) is associated with higher income, which may influence late-life cognitive health through multiple, nonmutually exclusive pathways.

description: The controlled catalytic functionalization of alkanes via the activation of C–H bonds is a significant challenge. Although C–H activation by transition metal catalysts is often suggested to operate via intermediate σ-alkane complexes, such transient species are difficult to observe due to their instability in solution. This instability may be controlled by use of solid/gas synthetic techniques that enable the isolation of single-crystals of well-defined σ-alkane complexes. Here we show that, using this unique platform, selective alkane C–H activation occurs, as probed by H/D exchange using D₂, and that five different isotopomers/isotopologues of the σ-alkane complex result, as characterized by single-crystal neutron diffraction studies for three examples. Low-energy fluxional processes associated with the σ-alkane ligand are identified using variable-temperature X-ray diffraction, solid-state NMR spectroscopy, and periodic DFT calculations. These observations connect σ-alkane complexes with their C–H activated products, and demonstrate that alkane-ligand mobility, and selective C–H activation, are possible when these processes occur in the constrained environment of the solid-state.

Essays in international portfolio choice and monetary policy
Creators: name: Yu, Changhua
Publisher: name: University of British Columbia
Year: 2012

description: Empirical evidence shows that equity home bias is a prevailing fact for most countries, but standard international monetary business cycle models with nominal bonds hardly generate equity home bias for plausible preference parameter values. By incorporating inflation-indexed bonds, I show in chapter 2 that international monetary business cycle models can explain home bias in equities. Inflation-indexed bonds can hedge real exchange rate risk and domestic equities serve as a hedge against domestic labor income risk conditional on real exchange rates. Moreover, this chapter accounts for counter-cyclical movements of net foreign asset positions. These results are robust in environments either with complete markets or with incomplete markets. How does international financial market integration alter international risk sharing? Chapter 3 develops a tractable center-periphery model with portfolio choice to investigate this issue. I compare three stages of financial integration. The first stage is financial autarky. The second stage is the central country becomes financially integrated with peripheral countries, but there is no financial integration between peripheral countries. The third stage is all financial markets are integrated into each other. From financial autarky to partial financial integration, volatility of consumption in all countries drops. From partial financial integration to full financial integration, volatility of consumption in peripheral countries decreases; however, consumption volatility rises in the central country when the central country is relatively large. When peripheral countries are large, the degree of international risk-sharing for all countries increases in the process of financial integration. What's the optimal monetary policy in an economy with financial frictions? Chapter 3 investigates optimal monetary policies in a dynamic stochastic general equilibrium model with sticky prices, sticky wages and credit-market imperfections. Credit frictions distort allocations and prices, and generate large volatility of aggregate variables via the financial accelerator. Policy-makers can take advantage of a debt deflation channel to push down volatility of endogenous variables through the financial decelerator. In the optimized linear interest rate rule, interest rate decreases in asset prices but the response is quantitatively small. This optimized rule exhibits high persistence. Within a class of simple linear interest rate rules, a strict inflation-targeting rule has a larger welfare loss.

description: We explore the discovery potential of W' and Z' boson searches for various SU(2) x SU(2) x U(1) models at the Large Hadron Collider (LHC), after taking into account the constraints from low energy precision measurements and direct searches at both the Tevatron (1.96 TeV) and the LHC (7 TeV). In such models, the W' and Z' bosons emerge after the electroweak symmetry is spontaneously broken. Two patterns of the symmetry breaking are considered in this work: one is SU(2)_L x SU(2)_2 x U(1)_X to SU(2)_L x U(1)_Y (BP-I), another is SU(2)_1 x SU(2)_2 x U(1)_Y to SU(2)_L x U(1)_Y (BP-II). Examining the single production channel of W' and Z' with their subsequent leptonic decays, we find that the probability of detecting W' and Z' bosons in the considered models at the LHC (with 14 TeV) is highly limited by the low energy precision data constraints. We show that observing Z' alone, without seeing a W', does not rule out new physics models with non-Abelian gauge extension, such as the phobic models in BP-I. Models in BP-II would predict the discovery of degenerate W' and Z' bosons at the LHC.

description: Die vorliegende Arbeit befasst sich mit den Fragestellungen, welche Stärken und Schwächen der Rekrutierungsprozess der Lernenden der Justiz des Kantons Bern aufweist und welche Optimierungsmassnahmen sich davon ableiten lassen. Mittels vier qualitativen Experteninterviews mit Berufsbildenden wurde ein Überblick zum derzeitigen Rekrutierungsprozess verschafft. Dabei standen die vier Teilprozesse des Personalauswahlprozesses Anforderungsanalyse, Stellenanzeige, Personalmarketing und Auswahlverfahren im Fokus. Zum Teilprozess Personalmarketing wurde aufgrund der Ergebnisse der Experteninterviews eine zusätzliche quantitative Umfrage mit den derzeitigen Lernenden der Justiz durchgeführt. Die Ergebnisse beider Datenerhebungen zeigen, dass in allen vier Teilprozessen Stärken vorhanden sind. So werden Anforderungen definiert, in den Stellenanzeigen alle wichtigen Informationen aufgeführt und passend dargestellt. Für die Veröffentlichung der Stellen-anzeigen werden zudem geeignete Kanäle gewählt. Als Auswahlverfahren wird in einem ersten Schritt eine Vorabauswahl basierend auf den erhaltenen Bewerbungen vollzogen. An-schliessend erfolgt ein multimodales Interview. Neben den Stärken weist jeder Teilprozess auch Schwächen auf. So werden die Anforderungen lediglich intuitiv ermittelt, ohne standardisiertes Verfahren. Die Stellenanzeigen setzten kaum visuelle Reize wie beispielsweise mit einem Video. Die eingesetzten Personalmarketingmassnahmen zeigen zudem nicht die gewünschte Wirkung. Grund dafür ist, dass die Justiz meist unter dem Namen des Kantons Bern als Arbeitgeber läuft und die Massnahmen nicht die passende Zielgruppe ansprechen. Die im Auswahlverfahren eingesetzten Instrumente sind zudem ebenfalls nicht standardisiert. Für die Optimierung des Rekrutierungsprozesses wird daher unteranderem das Einsetzen von standardisierten und validierten Verfahren – wie beispielsweise der Fleishman Job Analysis Survey – empfohlen. Zudem sollten die bestehenden Personalmarketingmassnahmen den Zielgruppen angepasst sowie mit weiteren justizspezifischen Massnahmen wie beispielsweise einem Informationsanlass erweitert werden.

description: Aufgrund zunehmender Stressproblematik in der Arbeitswelt wird in der vorliegenden Bachelorarbeit untersucht, wie sich nach sechs Wochen Atemarbeit die kurzfristig kognitivemotionalen Stressfolgen von Mitarbeitenden der Baloise Versicherung AG, die ein erhöhtes Stresserleben aufweisen, verändern. Um die Fragestellung beantworten zu können, nahmen 12 Mitarbeitende für sechs Wochen an einem wöchentlich angebotenen Atemtraining der Baloise teil. Zusätzlich wendeten sie die Atemarbeit in diesem Zeitraum täglich fünf Minuten selbständig an. Nach Abschluss dieser sechs Wochen fanden qualitative Interviews statt, die mittels fokussierter Interviewanalyse ausgewertet wurden. Mithilfe eines Items zum Stresserleben wurde zusätzlich ein quantitativer Vorher-nachher Vergleich gewährleistet. Wie sich zeigt, treten grösstenteils positive Veränderungen auf, wobei Veränderung im Nervositätserleben hervorstechen. Atemarbeit dient somit als geeignetes Instrument, kognitiv-emotionalen Stressfolgen entgegenzuwirken. Weitere Einflussfaktoren wie Sport oder eine Ernährungsumstellung sollten trotzdem nicht vernachlässigt werden. Aufgrund der geringen Besuchenden-Anzahl des Atemtrainings vor Beginn der Untersuchung wurde zudem evaluiert, wie Mitarbeitende zukünftig zum Besuch des Atemtrainings motiviert werden können. Wie die Ergebnisse zeigen, ist die Motivierung durch Vorgesetzte, das betriebliche Gesundheitsmanagement oder durch bestehende Kursteilnehmende möglich. Weitere Motivationsaspekte sind vermehrte Bewerbungsmassnahmen über das betriebsinterne Intranet, die Darlegung positiver Auswirkungen der Atemarbeit sowie ein grösserer Spielraum betreffend Zeitraum und Sprache, in der das Atemtraining angeboten wird.

Hippocampus (Brain)

description: The hippocampal formation is composed of separate anatomical regions interconnected to form a circuit, and investigating abnormal hippocampal function is most revealing at the level of these regions. Until recently, regional analysis of the hippocampal formation could be performed only in animals or in human postmortem tissue. Here, we report a method using functional magnetic resonance imaging that evaluates the hippocampal regions in vivo, and we use this method to study elderly with normal memory, with isolated memory decline, and with probable Alzheimer's disease (AD). Although age-related memory decline occurs commonly, the cause of this decline remains unknown, with disagreement as to whether this decline represents one or more etiologies. Analysis revealed two distinct patterns of regional dysfunction among elderly with isolated memory decline--one pattern similar to that found in elders with AD, involving all hippocampal regions, and a second pattern with dysfunction restricted to only one hippocampal region, the subiculum. These results offer direct evidence of hippocampal dysfunction associated with memory decline in the elderly, and implicate both predementia AD and non-AD processes as possible underlying causes

description: A search for narrow, high-mass resonances decaying to electron or muon pairs has been performed using pp collision data collected at sqrt(s) = 7 TeV by the CMS experiment in 2011. The data sample corresponds to an integrated luminosity of approximately 5 inverse femtobarns. The event yields observed in the signal regions are consistent with predictions of the standard model backgrounds, and upper limits on the cross section times branching fraction for a resonance decaying to dileptons are extracted from a shape analysis of the dilepton invariant mass distribution. The resulting mass limits at 95% confidence level are 2330 GeV for the Z' in the Sequential Standard Model, 2000 GeV for the superstring-inspired Z'(psi) resonance, 890 (540) GeV for the Stueckelberg extension Z'(St) with the mass parameter epsilon = 0.06 (0.04), and 2140 (1810) GeV for Kaluza--Klein gravitons with the coupling parameter k/Mbar(Pl) of 0.10 (0.05). These limits are the most stringent to date.

description: In der vorliegenden Tagebuch- und Interviewstudie (N=20) wurde untersucht, welche individuellen und tätigkeitsbezogenen Einflussfaktoren auf die Wahl des Arbeitsortes im Kontext der mobil-flexiblen Arbeit entscheidend sind. Zur Beantwortung der Fragestellung wurden niedrig mobile Personen mit hoch mobilen Personen kontrastiert. Die wichtigsten personenbezogenen Einflussfaktoren waren eine verbesserte Work-Life-Balance, Flexibilität, Autonomie und der Wegfall der Pendelzeit. Im Rahmen der Tagebuchstudie wurde der Einfluss von fünf Tätigkeitsarten auf die Wahl des Arbeitsortes untersucht. Wie zu erwarten war, wählten Arbeitnehmende für kommunikative Arbeiten das Büro und für konzentrierte Arbeiten das Homeoffice als Arbeitsort. Die Ausnahme bildeten Videokonferenzen, welche besonders bevorzugt zu Hause durchgeführt wurden. Es war auch die Tätigkeitsart, die niedrig mobile Personen zum grössten Anteil im Homeoffice erledigten. Typisch im Homeoffice waren auch Einzelarbeiten. Die Sequenzen an konzentrierter Einzelarbeit waren bei den untersuchten Personen signifikant länger im Homeoffice als im Büro. Typisch im Büro war der informelle Austausch. Da die konzentrierte Einzelarbeit mit spontanem Austausch im Spannungsfeld steht, muss von Arbeitnehmenden in Absprache mit dem Team eine vorsichtige Abwägung der Arbeitsortwahl vorgenommen werden. Zudem sollten Organisationen Mobilitätsprofile verschiedener Berufsgruppen definieren, um eine nachhaltige mobil-flexible Arbeitsweise zu unterstützen.

description: Gas-based time projection chambers (TPCs) have been shown to be highly sensitive X-ray polarimeters having excellent quantum efficiency while at the same time achieving large modulation factors. To observe polarization of the prompt X-ray emission of a Gamma-ray burst (GRB), a large area detector is needed. Diffusion of the electron cloud in a standard TPC could be prohibitive to measuring good modulation when the drift distance is large. Therefore, we propose using a negative ion TPC (NITPC) with Nitromethane (CH3NO2) as the electron capture agent. The diffusion of negative ions is reduced over that of electrons due to the thermal coupling of the negative ions to the surrounding gas. This allows for larger area detectors as the drift distance can be increased without degrading polarimeter modulation. Negative ions also travel ~200 times slower than electrons, allowing the readout electronics to operate slower, resulting in a reduction of instrument power. To optimize the NITPC design, we have measured gas gain with SciEnergy gas electron multipliers (GEMs) in single and double GEM configurations. Each setup was tested with different gas combinations, concentrations and pressures: P10 700 Torr, Ne+CO2 700 Torr at varying concentrations of CO2 and Ne+CO2+CH3NO2 700 Torr. We report gain as a function of total voltage, measured from top to bottom of the GEM stack, and as a function of drift field strength for the gas concentrations listed above. Examples of photoelectron tracks at 5.9 keV are also presented.

description: Objective: To determine the inter-rater reliability of a modification of the Memorial Sloan-Kettering (MSK) Staging for HIV-associated cognitive impairment. Methods: Data were abstracted on neurologic, neuropsychological, and functional status on 100 individuals participating at four sites in the Northeast AIDS Dementia (NEAD) Consortium cohort study, a longitudinal study of predictors of cognitive impairment in HIV-infected individuals. Neuropsychological performance was defined 1) based on the neuropsychologist’s global impression and 2) solely based on neuropsychological test scores. Raters at each site used the abstracted data to assign an MSK stage to each subject blind to any identifying information. Inter-rater reliability was assessed using kappa statistics. Agreement between computer-generated ratings and site-generated ratings was also assessed. Results: Kappa statistics for pair-wise agreement among the sites regarding MSK stage ranged from 0.70–0.91, representing good to excellent agreement between sites. Agreement between computer-generated ratings and site-generated ratings was in the good to excellent range (0.62–0.79). Conclusions: The authors have modified the MSK rating scale and developed a reliable instrument that can be used in multicenter studies. This instrument will be useful in staging HIV-dementia in future longitudinal studies and will be valuable in increasing accuracy of clinicopathologic studies.

description: Mit einer Mixed-Method aus Beobachtungen, Interviews und einem Online-Fragebogen untersucht diese Bachelorarbeit die Frage, wie die Selbstorganisation der Mitarbeitenden im Praxisunternehmen durch die Optimierung von bestehenden und durch die Implementierung von neuen Austausch- und Beratungsgefässen gefördert werden kann. Das übergeordnete Ziel ist, dass das Praxisunternehmen durch einen besseren Wissenstransfer adäquater auf die Herausforderungen der momentanen schnellen, komplexen und unsicheren Welt reagieren kann. Zuerst werden relevante Begriffe und Theorien zu agilen Unternehmensformen, Selbstorganisation, Wissensmanagement und Austausch- sowie Beratungsgefässen erläutert. Die Ergebnisse der Mixed-Method zeigen, dass die Dokumentation von Wissen im Unternehmen am wenigsten zur Selbstorganisation befähigt. Obwohl die Mitarbeitenden Interesse an einem Wissensaustausch haben, teilen sie tendenziell weniger individuelles Wissen aus eigener Initiative. Des Weiteren wurde kein statistisch signifikanter Unterschied zwischen den Inter- und Supervisionen hinsichtlich ihrer Befähigung zur Selbstorganisation festgestellt. Die Mittelwerte zeigen die Tendenz, dass Intervisionen weniger zur Selbstorganisation befähigen als Supervisionen. Im Diskussionsteil wird die Fragestellung damit beantwortet, dass in Austausch- und Beratungsgefässen ein Wissenstransfer erfolgt. Wird dieser verbessert, könnten die Austausch- und Beratungsgefässe die Mitarbeitenden zu mehr Selbstorganisation befähigen. Ausgehend aus den Ergebnissen und der Diskussion werden dementsprechende Handlungsempfehlungen abgeleitet, darunter die Implementierung einer Wissenslandkarte zur Lokalisierung von Wissen und Wissenslücken, die Sammlung übergeordneter Themen im Team zur Diskussion mit externen oder internen Fachpersonen und die Reflexion von Intervisionen zur Erleichterung von Feedback und Beobachtungen. Diese Handlungsempfehlungen sollen den Wissenstransfer in Austausch- und Beratungsgefässen verbessern und somit die Selbstorganisation der Mitarbeitenden fördern.

Conociendo la problemática ambiental que actualmente enfrentan los cuerpos de agua dominicanos nos abocamos a desarrollar una línea de trabajo sobre ecosistemas de agua dulce, presentando propuestas sobre la importancia de la colección de referencia de macroinvertebrados de la universidad y el uso de los macroinvertebrados en el biomonitoreo acuático. Entre 2016 y 2017 se han presentado en la comunidad científica local ponencias acerca del valor de los macroinvertebrados acuáticos y la bioindicación. Se ha organizado en Santo Domingo un taller sobre experiencias similares como las de Panamá. Se obtuvo el aval para dos tesis de licenciatura en biología y se publicó la primera lista de familias de macroivertebrados acuáticos de la isla Española. Con la aprobación del proyecto "Adaptación de los índices Biological Monitoring Working Party (BMWP) e Índice Biótico de Familias (IBF) para la República Dominicana y su uso como herramienta de monitoreo de la calidad biológica de los cuerpos de agua dulce", por el Ministerio de Educación Superior, Ciencia y Tecnología, se propone sentar las bases para la incorporación de la biota acuática en las evaluaciones ambientales. Las actividades del proyecto se realizarán con la colaboración de un colega costarricense con vasta experiencia en el área. La implantación de un sistema de monitoreo de macroinvertebrados dulceacuícolas facilitará la determinación del grado de alteración de los ríos en la República Dominicana. Se espera crear protocolos de monitoreo, guías de identificación de familias de macroinvertebrados acuáticos, así como fortalecer las colecciones de referencia y las capacidades locales en cuanto al uso de macroinvertebrados acuáticos como indicadores ambientales.

description: Polycrystalline samples of LaNi2(Ge{1-x}P{x})2 (x = 0, 0.25, 0.50, 0.75, 1) were synthesized and their properties investigated by x-ray diffraction (XRD), heat capacity Cp, magnetic susceptibility chi, and electrical resistivity rho measurements versus temperature T. These compounds all crystallize in the body-centered-tetragonal ThCr2Si2-type structure. The rho(T) measurements indicate that all compositions in this system are metallic. The low-T Cp measurements yield a rather large Sommerfeld coefficient gamma = 12.4(2) mJ/mol K^2 for x = 0 reflecting a large density of states at the Fermi energy that is comparable with the largest values found for the AFe2As2 class of materials with the same crystal structure. The gamma decreases approximately linearly with x to 7.4(1) mJ/mol K^2 for x = 1. The chi measurements show nearly temperature-independent paramagnetic behavior across the entire range of compositions except for LaNi2Ge2, where a broad peak is observed at 300 K from chi(T) measurements up to 1000 K that may arise from short-range antiferromagnetic correlations in a quasi-two-dimensional magnetic system. High-accuracy Pade approximants representing the Debye lattice heat capacity and Bloch-Gruneisen electron-phonon resistivity functions versus T are presented and are used to analyze our experimental Cp(T) and rho(T) data, respectively. The T-dependences of rho for all samples are well-described by the Bloch-Gruneisen model, although the observed rho(300 K) values are larger than calculated from this model. A significant T-dependence of the Debye temperature determined from the Cp(T) data was observed for each composition. No clear evidence for bulk superconductivity or any other long-range phase transition was found for any of the compositions studied.

description: We describe the system of massive Weyl fields propagating in a background matter and interacting with an external electromagnetic field. The interaction with an electromagnetic field is due to the presence of anomalous magnetic moments. To canonically quantize this system first we develop the classical field theory treatment of Weyl spinors in frames of the Hamilton formalism which accounts for the external fields. Then, on the basis of the exact solution of the wave equation for a massive Weyl field in a background matter we obtain the effective Hamiltonian for the description of spin-flavor oscillations of Majorana neutrinos in matter and a magnetic field. Finally, we incorporate in our analysis the neutrino self-interaction which is essential when the neutrino density is sufficiently high. We also discuss the applicability of our results for the studies of collective effects in spin-flavor oscillations of supernova neutrinos in a dense matter and a strong magnetic field.

description: Background: For people with anorexia nervosa (AN), compulsive exercise is characterized by extreme concerns about the perceived negative consequences of stopping/reducing exercise, dysregulation of affect, and inflexible exercise routines. It is associated with increased eating disorder psychopathology and poor clinical outcome. However, its relationships with two important clinical issues, quality of life (QoL) and motivation to change, are currently unknown. This study aimed to assess the cross-sectional relationships between compulsive exercise, QoL, psychological distress (anxiety and depressive symptoms, and obsessive-compulsive traits) and motivation to change in patients with AN.

Method: A total of 78 adults with AN participated in this study, which was nested within a randomized controlled trial of psychological treatments for AN. At baseline (pre-treatment), participants completed questionnaires assessing compulsive exercise, eating disorder (ED) psychopathology, QoL, psychological distress and motivation to change.

Results: Baseline correlational analyses demonstrated a moderate positive relationship between compulsive exercise and ED psychopathology, and a weak positive relationship between compulsive exercise and psychological distress. There was a moderate negative relationship between compulsive exercise and eating disorder QoL.

Conclusions: These results indicate compulsive exercise is moderately associated with poorer QoL and weakly associated with higher distress. Targeting compulsive exercise in the treatment of anorexia nervosa may help reduce the burden of illness and improve patients’ engagement in treatment.

description: We discuss the prospects for improved upper limits on neutrino masses that may be provided by a core-collapse supernova explosion in our galaxy, if it exhibits time variations in the neutrino emissions on the scale of a few milliseconds as suggested by recent two-dimensional simulations. Analyzing simulations of such neutrino emissions using the wavelet technique adopted in [1], we find that an upper limit m_nu ~ 0.14 eV could be established at the 95% confidence level if the time variations in emissions were to be preserved during neutrino propagation to the Earth.

description: This study investigated the relationship between education and physical activity and the difference between a physiological prediction of age and chronological age (CA). Cortical and subcortical gray matter regional volumes were calculated from 331 healthy adults (range: 19-79 years). Multivariate analyses identified a covariance pattern of brain volumes best predicting CA (R(2) = 47%). Individual expression of this brain pattern served as a physiologic measure of brain age (BA). The difference between CA and BA was predicted by education and self-report measures of physical activity. Education and the daily number of flights of stairs climbed (FOSC) were the only 2 significant predictors of decreased BA. Effect sizes demonstrated that BA decreased by 0.95 years for each year of education and by 0.58 years for 1 additional FOSC daily. Effects of education and FOSC on regional brain volume were largely driven by temporal and subcortical volumes. These results demonstrate that higher levels of education and daily FOSC are related to larger brain volume than predicted by CA which supports the utility of regional gray matter volume as a biomarker of healthy brain aging.

description: Agriculture stands as a cornerstone of Ethiopia's economy, yet persistent challenges in productivity and self-sufficiency persist, largely attributed to fragmented land cultivation and inadequate farming systems. Despite being home to a predominantly agrarian population, Ethiopia has struggled to achieve agricultural self-sufficiency, primarily due to low productivity levels. In response to this pressing issue, the Ethiopian government has implemented agricultural extension programs, leveraging communication strategies to drive transformative change. These initiatives have been instrumental in disseminating crucial information and skills to farmers since the 1950s, aiming to enhance resource utilization and technological adoption. This study delves into the pivotal role of agricultural extension in bolstering production and empowering farmers, shedding light on its evolution and impact within the Ethiopian context. Drawing on insights from Alemu (2017), Mekonnen et al. (2016), Gerba (2018), Belay (2003), and NAEP (2001), the research elucidates the multifaceted dimensions of agricultural extension services, emphasizing their significance in equipping farmers with the knowledge and tools necessary to optimize production outcomes. By synthesizing empirical evidence and policy frameworks, the study offers valuable insights into the challenges and opportunities inherent in agricultural extension programs, underscoring their potential to drive sustainable agricultural development and socioeconomic progress in Ethiopia

description: We consider the 1D Expected Improvement optimization based on Gaussian processes having spectral densities converging to zero faster than exponentially. We give examples of problems where the optimization trajectory is not dense in the design space. In particular, we prove that for Gaussian kernels there exist smooth objective functions for which the optimization does not converge on the optimum.

description: Order Geophilomorpha Pocock, 1895 Referred material. 1 specimen: MACH.20: adult of undetermined sex, incomplete specimen. Locality. MACH.20: Mexico, Chiapas, Simojovel, La Pimienta site, 17°08ʹ29ʺ N, 092°45ʹ46ʺ W. Identification. MACH.20 without head or terminal segments, body with more than 40 pairs of legs; fossil specimen match Geophilomorpha but this shows poor preservation that makes a more detailed description difficult. Referred material. 1 specimen: G.2005.147.1.1, as seen in Ross et al. (2016: 46, fig. 2). Locality. Mexico, Chiapas? Simojovel area? The origin of this material is unproven; there are no data about the exact locality or strata provided by Ross et al. (2016). Remarks. Specimen undetermined; micrograph published in Ross et al. (2016). Accordingly, the specimens resemble Geophilomorpha. Ross et al. (2016) also referred to another geophilomorph specimen, which they identified as G.2007.67.10.1 (Ross and Sheridan 2013: 55, fig. 9), but this is the same specimen G.2005.147.1.1 (even the same photo) as presented in Ross et al. (2016: 46, fig. 2).
