Ashurst, C., & Hodges, J. (2010). Exploring business transformation: the challenges of developing a benefits realization capability. Journal of Change Management , 10 (2), 217-237.

The successful management of change continues to be a major issue for organizations. This article draws on rich qualitative data to provide evidence of issues faced by organizations as they try to realize benefits from investments in IT-enabled change, and as they try to develop and enhance their benefits realization capability. Several of these issues are not effectively covered by previous research, for example managing the overall portfolio of change initiatives and how to develop the capacity of the organization for benefits realization. The research also provides empirical evidence that supports the theoretical propositions from dynamic capability theory that routines (practices) are often similar across different organizations, and that organizations go through a number of stages in developing competences. A further contribution of the research is to develop an enhanced model of an organizational competence, which has important implications for the action required to develop competences.
Imes Discussion Paper Series Institute for Monetary and Economic Studies Bank of Japan Extracting Market Expectations from Option Prices : Case Studies in Japanese Option Markets Extracting Market Expectations from Option Prices: Case Studies in Japanese Option Markets

A b s t r a c t This paper focuses on the recently developing financial derivatives markets, and examines the usefulness of option prices as an information variable for monetary policy implementation. A set of option prices provides us with information on the whole probability distribution of the future values of underlying assets. Such information enables us to examine the development of market expectations. The paper estimates a time series of implied probability distributions from daily option prices on stock prices and long term government bond futures. The estimation is done for a sample of daily closing prices for the following three periods: (i) the period of collapsing bubble in stock market in 1989-90; (ii) the period of record low stock prices in 1992-94 1 ; and (iii) the period of increasing anxiety in the market about a possible deflationary spiral in 1995.

UvA-DARE Search for dark matter annihilation in the Wolf-Lundmark-Melotte dwarf irregular galaxy with H.E.S.S.

We search for an indirect signal of dark matter through very high-energy γ rays from the Wolf-Lundmark-Melotte (WLM) dwarf irregular galaxy. The pair annihilation of dark matter particles would produce Standard Model particles in the final state such as γ rays, which might be detected by ground-based Cherenkov telescopes. Dwarf irregular galaxies represent promising targets as they are dark matter dominated objects with well-measured kinematics and small uncertainties on their dark matter distribution profiles. In 2018, the five-telescopes of the high energy stereoscopic system observed the dwarf irregular galaxy WLM for 18 hours. We present the first analysis based on data obtained from an imaging atmospheric Cherenkov telescope for this subclass of dwarf galaxy. As we do not observe any significant excess in the direction of WLM, we interpret the result in terms of constraints on the velocity-weighted * Corresponding authors. cross section for dark matter pair annihilation h σ v i as a function of the dark matter particle mass for various continuum channels, as well as the prompt γγ emission. For the τ þ τ − channel, the limits reach a h σ v i value of about 4 × 10 − 22 cm 3 s − 1 for a dark matter particle mass of 1 TeV. For the prompt γγ channel, the upper limit reaches a h σ v i value of about 5 × 10 − 24 cm 3 s − 1 for a mass of 370 GeV. These limits represent an improvement of up to a factor 200, with respect to previous results for the dwarf irregular galaxies for TeV dark matter search. DOI: 10.1103/PhysRevD.103. 102002
Artificial Intelligence-Based Prediction of Crude Oil Prices Using Multiple Features under the Effect of Russia–Ukraine War and COVID-19 Pandemic

The effect of the COVID-19 pandemic on crude oil prices just faded; at this moment, the Russia–Ukraine war brought a new crisis. In this paper, a new application is developed that predicts the change in crude oil prices by incorporating these two global effects. Unlike most existing studies, this work uses a dataset that involves data collected over twenty-two years and contains seven different features, such as crude oil opening, closing, intraday highest value, and intraday lowest value. This work applies cross-validation to predict the crude oil prices by using machine learning algorithms (support vector machine, linear regression, and rain forest) and deep learning algorithms (long short-term memory and bidirectional long short-term memory). The results obtained by machine learning and deep learning algorithms are compared. Lastly, the high-performance estimation can be achieved in this work with the average mean absolute error value over 0.3786.

A global view on star formation: The GLOSTAR Galactic plane survey

Context. The Central Molecular Zone (CMZ), a ∼200 pc sized region around the Galactic Centre, is peculiar in that it shows a star formation rate (SFR) that is suppressed with respect to the available dense gas. To study the SFR in the CMZ, young stellar objects (YSOs) can be investigated. Here we present radio observations of 334 2.2 μm infrared sources that have been identified as YSO candidates. Aims. Our goal is to investigate the presence of centimetre wavelength radio continuum counterparts to this sample of YSO candidates which we use to constrain the current SFR in the CMZ. Methods. As part of the GLObal view on STAR formation (GLOSTAR) survey, D-configuration Very Large Array data were obtained for the Galactic Centre, covering −2° < l < 2° and −1° < b < 1° with a frequency coverage of 4–8 GHz. We matched YSOs with radio continuum sources based on selection criteria and classified these radio sources as potential H II regions and determined their physical properties. Results. Of the 334 YSO candidates, we found 35 with radio continuum counterparts. We find that 94 YSOs are associated with dense dust condensations identified in the 870 μm ATLASGAL survey, of which 14 have a GLOSTAR counterpart. Of the 35 YSOs with radio counterparts, 11 are confirmed as H II regions based on their spectral indices and the literature. We estimated their Lyman continuum photon flux in order to estimate the mass of the ionising star. Combining these with known sources, the present-day SFR in the CMZ is calculated to be ∼0.068 M⊙ yr−1, which is ∼6.8% of the Galactic SFR. Candidate YSOs that lack radio counterparts may not have yet evolved to the stage of exhibiting an H II region or, conversely, are older and have dispersed their natal clouds. Since many lack dust emission, the latter is more likely. Our SFR estimate in the CMZ is in agreement with previous estimates in the literature.
Retention of Prey Genetic Material by the Kleptoplastidic Ciliate Strombidium cf.

from the cryptophyte prey Teleaulax amphioxeia have been shown to keep their functionality for several days in the ciliate Strombidium cf. basimorphum. To investigate the potential retention of prey genetic material in this ciliate, we applied a molecular marker speciﬁc for this cryptophyte prey. Here, we demonstrate that the genetic material from prey nuclei, nucleomorphs, and ribosomes is detectable inside the ciliate for at least 5 days after prey ingestion. Moreover, single-cell transcriptomics revealed the presence of transcripts of prey nuclear origin in the ciliate after 4 days of prey starvation. These new ﬁndings might lead to the reconsideration of the mechanisms regulating chloroplasts retention in Strombidium ciliates. The development and application of molecular tools appear promising to improve our understanding on chloroplasts retention in planktonic protists.

We investigate the role of ENSO climate patterns on global economic conditions. The estimated model is based on a rich and novel monthly dataset for 20 economies, capturing 80.2% of global output (based on 2021 IMF data) over the period 1999:01 to 2022:03. The empirical evidence from an estimated global vector autoregression with local projections (GFAVLP) model links an El Ni˜no (EN) shock with higher output and inﬂation, corresponding with lower global economic policy uncertainty (GEPU). While a shock to the world oil and food price is inﬂationary, a food price shock leads to elevated GEPU, more so during a LN shock. A main ﬁnding is that an increase of the food price can be a source of global vulnerability. The ﬁndings indicate that the weather shock impact on global economic conditions is dependent on the climate state. Our result undermines existing studies connecting climate change and economic damage via statistical approach.
Bayesian inference for non-anonymous growth incidence curves using Bernstein polynomials: an application to academic wage dynamics

Abstract The paper examines the question of non-anonymous Growth Incidence Curves (na-GIC) from a Bayesian inferential point of view. Building on the notion of conditional quantiles of Barnett (1976. “The Ordering of Multivariate Data.” Journal of the Royal Statistical Society: Series A 139: 318–55), we show that removing the anonymity axiom leads to a complex and shaky curve that has to be smoothed, using a non-parametric approach. We opted for a Bayesian approach using Bernstein polynomials which provides confidence intervals, tests and a simple way to compare two na-GICs. The methodology is applied to examine wage dynamics in a US university with a particular attention devoted to unbundling and anti-discrimination policies. Our findings are the detection of wage scale compression for higher quantiles for all academics and an apparent pro-female wage increase compared to males. But this pro-female policy works only for academics and not for the para-academics categories created by the unbundling policy.

We suggest the rst large-scale international comparison of labor supply elasticities for 17 European countries and the US, separately by gender and marital status, with measurement di¤erences netted out by using a harmonized empirical approach and comparable data sources. We nd that own-wage elasticities are relatively small and much more uniform across countries than previously considered. Nonetheless, such di¤erences do exist, and are found not to arise from di¤erent tax-bene t systems, wage/hour level or demographic compositions across countries, suggesting genuine differences in work preferences across countries. Furthermore, three other important results for welfare analysis are consistent across countries: the extensive (participation) margin dominates the intensive (hours) margin; for singles, this leads to larger labor supply responses in low-income groups; and income elasticities are extremely small everywhere. Finally, the results for cross-wage elasticities in couples are opposed between regions, consistent with complementarity in spousesleisure in the US versus substitution in their household production in Europe.

RAPID analysis of variable stiffness beams and plates: Legendre polynomial triple‐product formulation

Numerical integration techniques are commonly employed to formulate the system matrices encountered in the analysis of variable stiffness beams and plates using a Ritz based approach. Computing these integrals accurately is often computationally costly. Herein, a novel alternative is presented, the Recursive Analytical Polynomial Integral Definition (RAPID) formulation. The RAPID formulation offers a significant improvement in the speed of analysis, achieved by reducing the number of numerical integrations that are performed by an order of magnitude. A common Legendre Polynomial basis is employed for both trial functions and stiffness/load variations leading to a common form for the integrals encountered. The Legendre Polynomial basis possesses algebraic recursion relations that allow these integrals to be reformulated as triple‐products with known analytical solutions, defined compactly using the Wigner (3j) coefficient. The satisfaction of boundary conditions, calculation of derivatives and transformation to other bases is achieved through combinations of matrix multiplication, with each matrix representing a unique boundary condition or physical effect, therefore permitting application of the RAPID approach to a variety of problems. Indicative performance studies demonstrate the advantage of the RAPID formulation when compared to direct analysis using Matlab's ‘integral’ and ‘integral2’. Copyright © 2017 John Wiley & Sons, Ltd.
Intensity mapping of H-alpha, H-beta, [OII] and [OIII] lines at z<5

Intensity mapping is now becoming a useful tool to study the large-scale structure of the universe through spatial variations in the integrated emission from galaxies and the intergalactic medium. We study intensity mapping of the H-alpha6563A, [OIII]5007A, [OII]3727A and H-beta4861A lines at 0.8<z<5.2. The mean intensities of these four emission lines are estimated using the observed luminosity functions (LFs), cosmological simulations, and the star formation rate density (SFRD) derived from observations at z<5. We calculate the intensity power spectra and consider the foreground contamination of other lines at lower redshifts. We use the proposed NASA small explorer SPHEREx (the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) as a case study for the detectability of the intensity power spectra of the four emission lines. We also investigate the cross correlation with the 21-cm line probed by CHIME (the Canadian Hydrogen Intensity Mapping Experiment), Tianlai experiment and SKA (the Square Kilometer Array) at 0.8<z<2.4. We find both the auto and cross power spectra can be well measured for the four lines at z<3, especially for the H-alpha, [OIII] and [OII] lines. Finally, we estimate the constraint on the SFRD from intensity mapping, and find we can reach accuracy higher than 7% at z<4, which is better than usual measurements using the LFs of galaxies.
The effect of the prolonged competitive season on semi-elite female volleyball players’ physical performance

Despite the literature on the changes in the physical performance characteristics of elite female athletes during the competition period, up to this date, there was no study of the physical performances of both the aerobic and anaerobic contented of the semi- elite female volleyball players over the competitive season. For this reason, this study was carried out in order to determine the effect of prolonged competitive season on semi-elite female volleyball players' physical performance. Volunteer 47 athletes were recruited from same group of division III in Turkey Women Volleyball League. During competitive season, athletes took part in an official match and 3-4 training seasons per week. Body mass, VO 2 max, 20m sprint, agility, vertical jumping, explosive power, aerobic and anaerobic power were assessed before and after 22-week competitive season. Normality data was primarily tested with Shapiro-Wilk and evaluated with Wilcoxon test because of abnormal distribution. There was significant improvement in VO 2 max (2.26%), 20 m sprint time (2.1%), agility (1.6%), vertical jump (2.99%), explosive power (3.5%), maximal anaerobic power (6.35%), whereas decrease in minimum (-5.8%) and average anaerobic (-30.66%) power (p<0.05), but decrease in body mass wasn't significant. This study indicated that prolonged competitive season had negative effect on anaerobic capacity and positive effect on agility, sprint, VO 2 max, vertical jumping and explosive power in the semi-elite female volleyball players.
The International Archives of the Photogrammetry , Remote Sensing and Spatial Information Sciences

High performance scanning is a routine part of the digital photogrammetric production workflow. Modern scanners offer geometric precision similar to analytical plotters and high quality CCD sensors capable of faithfully capturing the information in the aerial photograph at 12 bits per channel to provide excellent dynamic range and tonal set-up. Modern practice is typically based on scanning positive or negative roll films. One of the critical requirements of the best scanners is high optical resolution at very high speed, motivated by the desire to complete roll-film scans overnight. Currently this can be done on the Leica DSW600 Digital Scanning Workstation for black and white photography owing to its industry fastest scan times of 2 minutes per 23 x 23 cm frame. No scanner can yet do this for a 500 foot colour roll. Recent improvements attempt to extend this performance on the DSW to colour, while at the same time improving image quality and control. Leica Geosystems has undertaken a number of innovations aimed at these goals, including: large format 12-bit sensor; novel LED illumination system, to increase amount and uniformity of light, enlarge the illuminated area to maximize scanning speed, reduce cost and improve reliability; coatings on stage plate and cover glass to eliminate Newton Rings; higher performance linear encoders to optimise geometric integrity; software refinements, including ease-of-use features and JPEG2000. These advances are incorporated in a new model, the DSW700, but most are available to users of existing scanners by means of a well defined upgrade program.
Metastatic potential in clonal melanoma cells is driven by a rare, early-invading subpopulation

Metastasis occurs when tumor cells leave the primary tumor site and disseminate to distal organs. Most cells remain in the primary tumor, however, the circumstances that allow certain cells to drive this dissemination remain unclear. Here, we show that rare, highly invasive melanoma cells can appear even within clonal cell lines due to non-genetic fluctuations. These differences were intrinsic to the cells independent of their external context, and were marked by transiently high levels of SEMA3C expression. The invasive subpopulation drove dissemination of tumor cells to distal locations in a mouse model of melanoma. The transcription factor NKX2.2 emerged as a regulator of the proportion of invasive cells. There was an overall tradeoff between proliferation and invasion in single cells. Our results suggest that phenotypes like metastasis can be the result of intrinsic differences between single cells. Anti-rat secondary antibody was used 1:500 dilution for 20 minutes at room temperature with gentle rotation to mix the cells. Cells were washed with FACS buffer and resuspended in FACS buffer. Cells were sorted on FACSJazz Sorter or MoFlo Astrios Sorter at the Flow Cytometry Core Laboratory The Sorted cells were collected in 15ml conical tubes, pelleted, resuspended in fresh media and plated on tissue culture treated 24 or 6 well plates (Falcon brand, Thermo Fisher Scientific). Cells were allowed to recover overnight and used for various assays. Histology Core. 6 microns sections were placed on positively charged SuperFrost Plus Slides Fisher Scientific) and immediately fixed in 4% formaldehyde for 10 min at room temperature. Slides were washed twice in PBS and stored in 70% ethanol in LockMailer microscope slide jars at 4°C. For staining, slides were removed from 70% ethanol and transferred to a LockMailer jar containing Wash Buffer (2X SSC, 10% formamide) for 1-2 minutes and treated with 1000µl 8%SDS for 1 minute. Slides were tipped on the side to remove the 8%SDS and transferred to Wash Buffer for 2 minutes. 50µl staining solution was prepared for each slide by adding 1µl of the probe in the hybridization buffer (10% dextran sulfate, 2X SSC, 10% formamide). After the addition of staining solution, a cover slip was added on the slide and slides were stored in a humidified chamber at 37°C overnight. Next day, slides were transferred to a LockMailer jar containing Wash Buffer for 2 washes of 30 minutes each at 37°C. During the second wash, DAPI (1:10000) was added. Slides were removed from Wash Buffer and transferred to a LockMailer jar containing 2X SSC for 1 minute. Next, 50µl 2X SSC was added to the slide, secured with a coverslip and sealed using rubber cement (Elmer) and allowed to dry before imaging.
Appendix: 3D Shape Generation and Completion through Point-Voxel Diffusion

We present additional generation metrics in Table 1, following PointFlow [9]. We report coverage (COV), which measures the fraction of point clouds in the reference set that are matched to at least one point cloud in the generated set. We further report minimum matching distance (MMD), which measures for each point cloud in a reference set, the distance to its nearest neighbor in the generated set. Note that these generation metrics can vary depending on implementation and do not necessarily correlate to generation quality, as discussed in [9]. Table 2 includes generation results on Airplane, Chair, Car compared with the voxel-diffusion model, Vox-Diff, as described in the main paper, evaluated using the 1-NN metric. By generating less noisy point clouds, PVD significantly outperforms Vox-Diff.
