description: With the rapid development of the Internet, online customer reviews (OCR) have become an important part of online shopping platforms that provides a wealth of information. In this paper, I proposed two different models to predict the helpfulness of an OCR using the data from online electronics review at Amazon.com. I built a random forest classifier using content, readability and metadata of the reviews and reached a 75% of accuracy. I also found that the most helpful feature in this model is the star-rating of the review. The other models proposed in this paper are deep learning NLP models like LSTM and BERT. These models can help us solve the “cold start” problem of text mining. Based on the research, online shopping platforms could use the helpfulness prediction to pre-rank the review, which could benefit both the platform itself and their customers.

description: We present the combined analysis of the metal content of 83 objects in the redshift range 0.09-1.39, and spatially-resolved in the 3 bins (0-0.15, 0.15-0.4, >0.4) R500, as obtained with similar analysis using XMM-Newton data in Leccardi & Molendi (2008) and Baldi et al. (2012). We use the pseudo-entropy ratio to separate the Cool-Core (CC) cluster population, where the central gas density tends to be relatively higher, cooler and more metal rich, from the Non-Cool-Core systems. The average, redshift-independent, metal abundance measured in the 3 radial bins decrease moving outwards, with a mean metallicity in the core that is even 3 (two) times higher than the value of 0.16 times the solar abundance in Anders & Grevesse (1989) estimated at r>0.4 R500 in CC (NCC) objects. We find that the values of the emission-weighted metallicity are well-fitted by the relation $Z(z) = Z_0 (1+z)^{-γ}$ at given radius. A significant scatter, intrinsic to the observed distribution and of the order of 0.05-0.15, is observed below 0.4 R500. The nominal best-fit value of $γ$ is significantly different from zero in the inner cluster regions ($γ= 1.6 \pm 0.2$) and in CC clusters only. These results are confirmed also with a bootstrap analysis, which provides a still significant negative evolution in the core of CC systems (P>99.9 per cent). No redshift-evolution is observed when regions above the core (r > 0.15 R500) are considered. A reasonable good fit of both the radial and redshift dependence is provided from the functional form $Z(r,z)=Z_0 (1+(r/0.15 R500)^2)^{-β} (1+z)^{-γ}$, with $(Z_0, β, γ) = (0.83 \pm 0.13, 0.55 \pm 0.07, 1.7 \pm 0.6)$ in CC clusters and $(0.39 \pm 0.04, 0.37 \pm 0.15, 0.5 \pm 0.5)$ for NCC systems. Our results represent the most extensive study of the spatially-resolved metal distribution in the cluster plasma as function of redshift.

description: This study examines how irregular surfaces and debonding affect jute/epoxy composites. The study used micromechanics and finite element (FE) analysis to investigate properties such as elastic modulus in the longitudinal (E1) and transverse (E2) directions, major (ν12) and minor (ν21) Poisson’s ratios, and interfacial stresses (σ1, σ2, and τ12, τ23, τ13). The FE models were validated using experimental and analytical results, which showed good agreement. Then, the FE model was extended to analyse the influence of different fibre volume fractions (Vf) on jute/epoxy composites with varied irregular surfaces (IRS%) and debonding (DBS%). The interfacial stress was compared across these variables. DBS% caused significant variation in E2 and σ2, while IRS% led to out-of-shear stresses that crossed the threshold. An increase in IRS% and DBS% at a constant fibre volume fraction did not significantly affect E1. However, increasing Vf from 10–70% increased E1 by 168%. E2, on the other hand, decreased with Vf by 63–68%. Both IRS% and DBS% had a significant influence on interfacial stresses.

description: Agile organisations address changes with ease and speed. These changes are tackled through the concept of ongoing agility, using a sense-respond process, composed of sensing, decision-making, and acting. Increasingly, however, unexpected events require a different agility response. In this study, we propose and empirically examine how improvisational agility – conceptualised as organisation improvisational capability, the ability to sense and respond to unexpected events with speed and creativity – is a type of agility better suited for unanticipated events. Specifically, we focus on the improvisational agility sense-respond process. Using four exploratory cases, we find that organisations can leverage existing ongoing agility mechanisms for improvisational agility and, through learning, can leverage improvisational agility in ongoing agility. We also explain how different components of information management capability support improvisational agility, depending on the unexpected events and the need for speed or creativity.
Fusion rules for the Temperley-Lieb algebra and its dilute generalisation
Creators: name: Belletête, Jonathan
Publisher: name: arXiv
Year: 2015
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The Temperley-Lieb (TL) family of algebras is well known for its role in building integrable lattice models. Even though a proof is still missing, it is agreed that these models should go to conformal field theories in the thermodynamic limit and that the limiting vector space should carry a representation of the Virasoro algebra. The fusion rules are a notable feature of the Virasoro algebra. One would hope that there is an analogous construction for the TL family. Such a construction was proposed by Read and Saleur [Nucl. Phys. B 777, 316 (2007)] and partially computed by Gainutdinov and Vasseur [Nucl. Phys. B 868, 223-270 (2013)] using the bimodule structure over the Temperley-Lieb algebras and the quantum group Uq(sl2). We use their definition for the dilute Temperley-Lieb (dTL) family, a generalisation of the original TL family. We develop a new way of computing fusion by using induction and show its power by obtaining fusion rules for both dTL and TL. We recover those computed by Gainutdivov and Vasseur and new ones that were beyond their scope. In particular, we identify a set of irreducible TL- or dTL-representations whose behavior under fusion is that of some irreducibles of the CFT minimal models.

description: Many natural systems are difficult to predict because of how their behaviour in the past influences how they behave in the future. This is referred to as memory. These complex systems come in all shapes and sizes ranging from weather patterns, the signals in your brain, and even to interacting quantum particles. Despite the surprising diversity in where complex processes appear in nature, they share much in common because they all have memory. This thesis shows that accounting for the hidden memory in complex systems allows us to better describe consciousness, build new energy-efficient materials, and understand quantum mechanics.

Niangara Free-tailed Bat Mops niangarae French: Tadaride de Niangara / German: Niangara-Bulldogfledermaus / Spanish: Mops de Niangara Other common names: Niangara Mops Bat, Niangaran Mops Bat Taxonomy. Mops niangarae J. A. Allen, 1917, “Niangara, northeastern Belgian Congo [= DR Congo].” Although some consider Mops niangarae to be a subspecies or synonym of either M. congicus or M. trevori, its skull apparently differs from both these species, so it is provisionally retained as a distinct species pending formal revision of the M. congicus / trevori group. Monotypic. Distribution. Known only from type locality in extreme NE DR Congo. Descriptive notes. Head—body 91 mm,tail 34 mm, ear 22 mm, forearm 52 mm (type specimen). Fur is short, uniform rusty brown above, with no grizzling or spots; underside yellowish brown, paler and more yellowish on chest, apparently lacking contrasting mid-ventral markings or flank-stripe, as these are not mentioned in type description. Upper lip has more than seven well-defined wrinkles on each side and many spoon-hairs. Wings and uropatagium are dark brown. Ears are dark brown; type description mentioned ears being separate without interaural band of skin connecting inner margins, but subsequent inspection of holotype suggests that this apparent absence is an artefact of specimen preparation, and in fact an interaural band lacking cartilaginous support but bearing a broad, low erectile crest is present. Tragus is minute; antitragus is small and low. Anterior palate is closed and basisphenoid pits are deep and large. As is typical for Mops, cusps on M” have third ridge reduced. Habitat. The type locality of the Niangara Free-tailed Bat is represented by a mosaic of lowland rainforest and grassland savanna. Food and Feeding. No information. Breeding. No information. Activity patterns. Niangara Free-tailed Bats are nocturnal and apparently roost in the hollows of trees. Movements, Home range and Social organization.

Organizing System for AYA Resource and Services: Descriptive Schema for Categorizing Resources for the AYA Cancer Population
Creators: name: Lowry, Kathleen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This Master’s project documents the development of a system for organizing or categorizing resources, aimed to serve the population of Adolescent and Young Adult cancer patients (AYAs). Historically, the AYA population has been under-researched (Smith et al., 2012), with cancer steadily reported as a leading cause of death, behind suicide, for AYAs (Heron, 2019). As recent as 2010, research really began to focus on identifying the unmet needs for the population and addressing the gaps in medical care. The research identified a vulnerable subgroup of the AYA population, while conclusively revealing unaddressed needs and inconsistencies in care among all AYA cancer patients in the US. The focus on the development of a system for organizing resources or services, aimed specifically at addressing the research-identified obstacles and gaps in AYA cancer patient care in the US. The results of this Master’s project are intended to be generalizable across platforms and organizations.

description: The over-dense environments of protoclusters of galaxies in the early Universe (z>2) are expected to accelerate the evolution of galaxies, with an increased rate of stellar mass assembly and black hole accretion compared to co-eval galaxies in the average density `field'. These galaxies are destined to form the passive population of massive systems that dominate the cores of rich clusters today. While signatures of accelerated growth of galaxies in the SSA22 protocluster (z=3.1) have been observed, the mechanism driving this remains unclear. Here we show an enhanced rate of galaxy-galaxy mergers could be responsible. We morphologically classify Lyman-break Galaxies (LBGs) in the SSA22 protocluster and compare these to those of galaxies in the field at z=3.1 as either active mergers or non-merging using Hubble Space Telescope ACS/F814W imaging, probing the rest-frame ultraviolet stellar light. We measure a merger fraction of 48+/-10 per cent for LBGs in the protocluster compared to 30+/-6 per cent for the field. Although the excess is marginal, an enhanced rate of mergers in SSA22 hints that galaxy-galaxy mergers are one of the key channels driving accelerated star formation and AGN growth in protocluster environments.

description: Spatially and temporally varying selection can maintain genetic variation within and between populations, but it is less well known how these forces influence divergence between closely related species. We identify the interaction of temporal and spatial variation in selection and their role in either reinforcing or eroding divergence between two closely related Mimulus species. Using repeated reciprocal transplant experiments with advanced generation hybrids, we compare the strength of selection on quantitative traits involved in adaptation and reproductive isolation in Mimulus guttatus and Mimulus laciniatus between two years with dramatically different water availability. We found strong divergent habitat-mediated selection on traits in the direction of species differences during a drought in 2013, suggesting that spatially varying selection maintains species divergence. However, a relaxation in divergent selection on most traits in an unusually wet year (2019), including flowering time, which is involved in pre-zygotic isolation, suggests that temporal variation in selection may weaken species differences. Therefore, we find evidence that temporally and spatially varying selection may have opposing roles in mediating species boundaries. Given our changing climate, future growing seasons are expected to be more similar to the dry year, suggesting that in this system climate change may actually increase species divergence.
Wirtschaftliche Unternehmen und soziales Engagement: Eine qualitative Forschungsarbeit zum sozialen Engagement von wirtschaftlichen Unternehmen aus Sicht der Sozialen Arbeit

description: «The Purpose of Business is Business» – Milton Friedman  Dieser Satz des Ökonomen Milton Friedman hat für lange Zeit die Wirtschaft geprägt. Doch im Jahr 2022 lässt sich daran zweifeln, ob dies noch zeitgemäss ist. Wirtschaftliche Unternehmen sind in den letzten Jahren vermehrt im sozialen oder ökologischen Bereich tätig und realisieren neben ihrem Kerngeschäft soziale Projekte, unterstützen durch Spenden oder Lancieren eigene nachhaltige Produktlinien. In der vorliegenden Bachelorarbeit wird deshalb aus der Perspektive der Sozialen Arbeit der Blick auf die sozialen Engagements von wirtschaftlichen Unternehmen gerichtet. Dabei wird untersucht, welche Formen von sozialem Engagement in NPOs bis anhin ausgeübt werden, wie wirksam die Zusammenarbeit zwischen NPOs und wirtschaftlichen Unternehmen ist und welche Voraussetzungen für die Umsetzung der sozialen Engagements erfüllt sein müssen. Dies wird mittels einer qualitativen Forschung untersucht, in welcher leitfadengestützte Interviews verwendet werden. Insgesamt werden fünf Interviews durchgeführt, drei davon mit Führungspersonen aus wirtschaftlichen Unternehmen und zwei mit Führungspersonen aus sozialen Organisationen. Im Rahmen der Bachelorarbeit wird aufgezeigt, dass die wirtschaftlichen Unternehmen und die Soziale Arbeit ähnliche Voraussetzungen für eine Zusammenarbeit miteinander nennen. Dennoch distanzieren sich die NPOs von gewissen Unternehmen, deren Engagement nicht glaubhaft ist. In diesem Zusammenhang wird deutlich, dass sich die Soziale Arbeit weder für, noch gegen soziale Engagements von Unternehmen ausspricht. Diese Bachelorarbeit gibt damit Anlass zur grundsätzlichen Auseinandersetzung mit der Thematik in der Sozialen Arbeit.

description: Microvariability consists in small time scale variations of low amplitude in the photometric light curves of quasars, and represents an important tool to investigate their inner core. Detection of quasar microvariations is challenging for their non-periodicity, as well as the need for high monitoring frequency and high signal-to-noise ratio. Statistical tests developed for the analysis of quasar differential light curves usually show either low power or low reliability, or both. In this paper we compare two statistical procedures that include several stars to perform tests with enhanced power and high reliability. We perform light curve simulations of variable quasars and non-variable stars, and analyze them with statistical procedures developed from the F-test and the analysis of variance. The results show a large improvement in the power of both statistical probes, and a larger reliability, when several stars are included in the analysis. The results from the simulations agree with those obtained from observations of real quasars. The high power and high reliability of the tests discussed in this paper improve the results that can be obtained from short and long time scale variability studies. These techniques are not limited to quasar variability; on the contrary, they can be easily implemented to other sources such as variable stars. Their applications to future research and to the analysis of large field photometric monitoring archives can reveal new variable sources.

description: This study provides insights into the decision-making process archivists and librarians undergo when considering incorporating crowdsourcing elements into a digital project. The research was conducted via semi-structured interviews with eight American archivists and librarians that have conducted a crowdsourcing project. The study found that these professionals chose crowdsourcing as a tool for a variety of reasons and, while they discussed many challenges associated with crowdsourcing, they believed their projects a success. The study establishes four suggestions that will help library and archives managers be better prepared to manage and access the viability of potentially incorporating crowdsourcing elements into their digital projects.

description: We study an inhomogeneous three-orbital Hubbard model for the Cu-substituted iron pnictides using an extended real-space Green's function method combined with density functional calculations. We find that the onsite interactions of the Cu ions are the principal determinant of whether an electron dopant or a hole dopant is caused by the Cu substitution. It is found that the Cu substitution could lead to a hole doping when its onsite interactions are smaller than a critical value, as opposed to an electron doping when the interactions of Cu ions are larger than the critical value, which may explain why the effects of Cu substitution on the carrier density are entirely different in NaFe$_{1-x}$Cu$_x$As and Ba(Fe$_{1-x}$Cu$_x$)$_2$As$_2$. We also find that the effect of a doping-induced disorder is considerable in the Cu-substituted iron pnictides, and its cooperative effect with electron correlations contributes to the orbital-selective insulating phases in NaFe$_{1-x}$Cu$_x$As and Ba(Fe$_{1-x}$Cu$_x$)$_2$As$_2$.

description: Vorliegende Bachelorarbeit ist Beratungen im Kontext von Ambivalenz, Gewalt und Trauma in familiären Beziehungen gewidmet und fokussiert die psychosoziale Beratung chronifiziert gewaltbetroffener Personen unter Mitberücksichtigung des Schutzbedarfs mitbetroffener Kinder. Sämtliche Fragestellungen werden auf Basis aktueller Fachliteratur bearbeitet. Die Kernfragen sind, ob Opferberatungsstellen sowohl dem Beratungsbedarf chronifiziert gewaltbetroffener Personen als auch dem Schutzbedarf mitbetroffener Kinder gerecht werden können und wenn ja, wie. Die Fragestellung reifte im Kontext von praktischen Erfahrungen auf einer Opferberatungsstelle, wonach bei häuslicher Gewalt oft Kinder mitbetroffen sind, jedoch kaum Schutzmassnahmen greifbar scheinen. Die Arbeit stellt einleitend den Auftrag von Opferberatungsstellen gegenüber von häuslicher Gewalt betroffenen Personen vor. Anschliessend werden die Fragen nach den Beratungsbedarf chronifiziert gewaltbetroffener Personen einerseits und dem Schutzbedarf mitbetroffener Kinder andererseits beantwortet. Für die Beratung gewaltbetroffener Personen wird eine deutungssensible und traumasensible, motivierende Gesprächsführung erörtert. Betreffend den Schutzbedarf der Kinder wird aufgrund der bei häuslicher Gewalt bestehenden strukturellen Kindeswohlgefährdung argumentiert, dass eine Meldung an die Kindes- und Erwachsenenschutzbehörde indiziert ist. Auf Basis dieser Erkenntnisse wird ein Beratungsprozess vorgeschlagen, der Professionelle unterstützen soll, von häuslicher Gewalt Betroffene auf ihrem Veränderungsprozess zu begleiten und zugleich am Schutz der im gewalttätigen Familiensystem lebenden Kinder zu arbeiten.

description: A universal secondary relaxation process, known as the Johari-Goldstein (JG) $β$-relaxation process, appears in glass formers. It involves all parts of the molecule and is particularly important in glassy systems because of its very close relationship with the $α$-relaxation process. However, the absence of a J-G $β$-relaxation mode in colloidal glasses raises questions regarding its universality. In the present work, we study the microscopic relaxation processes in Laponite suspensions, a model soft glassy material, by dynamic light scattering (DLS) experiments. $α$ and $β$-relaxation timescales are estimated from the autocorrelation functions obtained by DLS measurements for Laponite suspensions with different concentrations, salt concentrations and temperatures. Our experimental results suggest that the $β$-relaxation process in Laponite suspensions involves all parts of the constituent Laponite particle. The ergodicity breaking time is also seen to be correlated with the characteristic time of the $β$-relaxation process for all Laponite concentrations, salt concentrations and temperatures. The width of the primary relaxation process is observed to be correlated with the secondary relaxation time. The secondary relaxation time is also very sensitive to the concentration of Laponite. We measure primitive relaxation timescales from the $α$-relaxation time and the stretching exponent ($β$) by applying the coupling model for highly correlated systems. The order of magnitude of the primitive relaxation time is very close to the secondary relaxation time. These observations indicate the presence of a J-G $β$-relaxation mode for soft colloidal suspensions of Laponite.

description: With the wide spread of online review platforms, online reviews and star ratings have been widely used by customers to determine the quality of business. However, overall star rating is not once-for-all measurement in summarizing the review because review writers are likely to differ in how would they evaluate different aspects of the restaurants. In this paper, we attempted to predict the rating a reviewer will assign mainly based on the review text as well as other features derived from the Yelp review dataset. We created dictionaries to identify the  combinations on sentence level and incorporated these new features. Our model achieved a fairly high level accuracy (84.61%). The contribution of aspect-related features was also discussed.

description: This paper investigates the frequency control of multi-machine power systems subject to uncertain and dynamic net loads. We propose distributed internal model controllers that coordinate synchronous generators and demand response to tackle the unpredictable nature of net loads. Frequency stability is formally guaranteed via Lyapunov analysis. Numerical simulations on the IEEE 68-bus test system demonstrate the effectiveness of the controllers.

description: Spatially and temporally varying selection can maintain genetic variation within and between populations, but it is less known how these forces influence divergence between closely related species. We identify the interaction of temporal and spatial variation in selection and their role in either reinforcing or eroding divergence between two closely related Mimulus species. Using repeated reciprocal transplant experiments with advanced generation hybrids, we compare the strength of selection on quantitative traits involved in adaptation and reproductive isolation in Mimulus guttatus and Mimulus laciniatus between 2 years with dramatically different water availability. We found strong divergent habitat mediated selection on traits in the direction of species differences during a drought in 2013, suggesting that spatially varying selection maintains species divergence. However, a relaxation in divergent selection on most traits in an unusually wet year (2019), including flowering time which is involved in pre-zygotic isolation, suggests that temporal variation in selection may weaken species differences. Therefore, we find evidence that temporally and spatially varying selection may have opposing roles in mediating species boundaries. Given our changing climate, future growing seasons are expected to be more similar to the dry year, suggesting that in this system climate change may actually increase species divergence.

description: We investigate the interrelationships among carbon performance, CEO Pay, executive compensation, financial performance and market value. Using data relating to non-financial firms from UK FTSE 350 from 2009 to 2018, our findings are fourfold. First, our results suggest that actual carbon performance is negatively associated with financial performance and market value of firms. Second, we document that self-reported carbon performance has no effect on financial performance. By contrast, we observe that self-reported carbon reduction initiatives performance has positive impact on market value. Third, our results suggest that CEO Pay, and executive compensation have positive moderating effect on the association between self-reported carbon performance and financial performance. In addition, we show that self-reported carbon performance–market value nexus is positively moderated by CEO Pay and executive compensation. Fourth, we observe that CEO Pay, and executive compensation have no moderating impact on actual carbon performance–market value nexus. Our findings demonstrate that while firms appear to employ compensation incentives to symbolically enhance their self-reported carbon performance, this does not result in actual carbon emission reduction. Our findings have key implications for policymakers.

description: We study the momentum distribution of the electrons in an extended periodic Anderson model, where the interaction, $U_{cf}$, between itinerant and localized electrons is taken into account. In the symmetric half-filled model, due to the increase of the interorbital interaction, the $f$ electrons become more and more delocalized, while the itinerancy of conduction electrons decreases. Above a certain value of $U_{cf}$ the $f$ electrons become again localized together with the conduction electrons. In the less than half-filled case, we observe that $U_{cf}$ causes strong correlations between the $f$ electrons in the mixed valence regime.

description: In previous work, the first and third authors introduced staircase tableaux, which they used to give combinatorial formulas for the stationary distribution of the asymmetric simple exclusion process (ASEP) and for the moments of the Askey-Wilson weight function. The fact that the ASEP and Askey-Wilson moments are related at all is quite surprising, and is due to Uchiyama-Sasamoto-Wadati. The ASEP is a model of particles hopping on a one-dimensional lattice of N sites with open boundaries, particles can enter and exit at both left and right borders. It was introduced around 1970 and is cited as a model for both traffic flow and translation in protein synthesis. Meanwhile, the Askey-Wilson polynomials are a family of orthogonal polynomials in one variable, they sit at the top of the hierarchy of classical orthogonal polynomials. So we have the relationship ASEP -- staircase tableaux -- Askey-Wilson moments It is well-known that Askey-Wilson polynomials can be viewed as the one-variable case of the multivariate Koornwinder polynomials, also known as the Macdonald polynomials for the type BC root system. It is natural then to ask whether one can generalize the relationships among the ASEP, Askey-Wilson moments, and staircase tableaux, in such a way that Koornwinder moments replace Askey-Wilson moments. In a recent work, we demonstrated a close connection between Koornwinder moments and the two-species ASEP (a particle model involving two species of particles with different "weights"). In this article we introduce rhombic staircase tableaux, and show that we have the relationship 2-species ASEP -- rhombic staircase tableaux -- Koornwinder moments In particular, we give formulas for the steady state distribution of the two-species ASEP and for Koornwinder moments, in terms of rhombic staircase tableaux.

description: The field of information and library science has long struggled with the lack of diversity in the workforce. In response, a number of programs have been created to encourage students of color to pursue careers within the library and information sciences. Despite this, the number of diverse individuals working in the field is still low. This paper explores instances of discrimination towards library and information science students of color and how these experiences shape their academic career and their outlook on the profession overall. Qualitative interviews were conducted with five students of color currently pursuing a master’s degree in library and information science and will be transcribed and analyzed for overarching themes. This paper intends to identify ways students of color in LIS master’s programs can be better supported.

description: Time series analysis and forecasting is an essential part of any holistic data analysis. Many prediction challenges depend on correctly assessing how the data changes over time. Several examples of time-series analyses that are traditionally seen are of univariate type, but it is hardly the case in a real-world setting. Any time series is influenced by multiple components, which includes its past and other constant or variable factors. This project is aimed at understanding multivariate time series models using the non-traditional time series analysis like clustering and sequence to sequence model using a long short-term memory architecture. The dataset on which this experiment is being applied is the Wikipedia web page traffic. The dataset contains around 145000 web pages and corresponding web page traffic from July 2015 to December 2016. Findings based on the hierarchical clustering model are presented in this study.
