Conversational Systems in Machine Learning from the Point of View of the Philosophy of Science—Using Alime Chat and Related Studies

This essay discusses current research efforts in conversational systems from the philosophy of science point of view and evaluates some conversational systems research activities from the standpoint of naturalism philosophical theory. Conversational systems or chatbots have advanced over the decades and now have become mainstream applications. They are software that users can communicate with, using natural language. Particular attention is given to the Alime Chat conversational system, already in industrial use, and the related research. The competitive nature of systems in production is a result of different researchers and developers trying to produce new conversational systems that can outperform previous or state-of-the-art systems. Different factors affect the quality of the conversational systems produced, and how one system is assessed as being better than another is a function of objectivity and of the relevant experimental results. This essay examines the research practices from, among others, Longino’s view on objectivity and Popper’s stand on falsification. Furthermore, the need for qualitative and large datasets is emphasized. This is in addition to the importance of the peer-review process in scientific publishing, as a means of developing, validating, or rejecting theories, claims, or methodologies in the research community. In conclusion, open data and open scientific discussion fora should become more prominent over the mere publication-focused trend.
Development of Composite Scaffolds Based on Cerium Doped-Hydroxyapatite and Natural Gums—Biological and Mechanical Properties

Hydroxyapatite (HAp) is a ceramic material composing the inorganic portion of bones. Ionic substitutions enhance characteristics of HAp, for example, calcium ions (Ca2+) by cerium ions (Ce3+). The use of HAp is potentialized through biopolymers, cashew gum (CG), and gellan gum (GG), since CG/GG is structuring agents in the modeling of structured biocomposites, scaffolds. Ce-HApCG biocomposite was synthesized using a chemical precipitation method. The obtained material was frozen (–20 °C for 24 h), and then vacuum dried for 24 h. The Ce-HApCG was characterized by X-Ray diffractograms (XRD), X-ray photoemission spectra (XPS), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), and energy dispersive spectroscopy (EDS). XRD and FTIR showed that Ce-HApCG was successfully synthesized. XRD showed characteristic peaks at 2θ = 25.87 and 32.05, corresponding to the crystalline planes (0 0 2) and (2 1 1), respectively, while phosphate bands were present at 1050 cm−1 and 1098 cm−1, indicating the success of composite synthesis. FESEM showed pores and incorporated nanostructured granules of Ce-HApCG. The mechanical test identified that Ce-HApCG has a compressive strength similar to the cancellous bone’s strength and some allografts used in surgical procedures. In vitro tests (MTT assay and hemolysis) showed that scaffold was non-toxic and exhibited low hemolytic activity. Thus, the Ce-HApCG has potential for application in bone tissue engineering.
When Reality Monitoring Fails: The Role of Imagination in Stereotype Maintenance

Research on reality monitoring (the process by which people distinguish memories of real events from memories of imagined events) suggests that the occurrence of imagined events can inflate the perceived frequency of corresponding real events. When the availability of real events is assessed, reality monitoring apparently fails to exclude some events that were only imagined. We conducted two experiments to examine how such failures in reality monitoring can contribute to the maintenance of social stereotypes. When subjects imagined members of occupational groups in the initial experiment, they tended to incorporate stereotyped traits into their imaginations, with specific traits determined by the contexts being imagined. This result suggests that imagined events do correspond with stereotype-confirming real events. In the second experiment, subjects read sentences that presented traits (stereotyped and nonstereotyped) in association with occupations with uniform frequency. They also imagined members of each occupation in situations relevant to particular stereotypic traits, but without presentation of the traits. In subsequent judgments of presentation frequency, subjects overestimated their exposure to stereotypic occupation-trait combinations, which replicated earlier studies. More important, subjects further overestimated the presentation frequency of imagined stereotypic combinations, which indicated the failure of subjects to distinguish their self-generated images from actual presentations. These results confirmed that stereotype-based imaginings can lead to inflated association of groups with their stereotypic traits. Such imaginal confirmation of social stereotypes may contribute to the self-perpetuating nature of these beliefs.

DESIGN PROPOSITIONS AND PROCESS STEPS FOR CURRICULUM DESIGN IN PROFESSIONAL HIGHER EDUCATION

Recent projections published by the EU show that in the years up to 2025, half of the jobs will require high level qualifications, while 65% of children entering primary school will be working in occupations that do not yet exist [1]. This implies higher demands on professionals as their tasks are becoming increasingly complex [2]. Higher education has to prepare students for this challenging future. Next to professional skills, higher education is expected to educate on problem solving, reasoning, decision making and creativity to ensure that professionals can flexibly adjust to rapid changes in their environment [3]. It is irrelevant to focus on the transfer of knowledge, rather on how students can use this information in their profession. It has been argued that students have to learn in an authentic context to facilitate better transfer for the student [4, 5, 6, 7] while learning knowledge, attitudes and skills in an integrated way [8]. To date, most literature focuses on the design of single courses and general pedagogical principles but fails to inform on how to practically designing complete outcome based curricula on professional higher education level (EQF level 5 and 6). Our proposal wants to bridge this gap through design science research [9, 10] at a university of applied sciences in Belgium. We asked the following question: How do we design supported and sustainable curricula that are directed towards learning outcomes? We developed 4 design propositions leading to 8 process steps that guide professionals towards developing future proof sustainable curriculum. Our process of implementation integrates well established insights from the literature as well as own field tested propositions in our process-steps of curriculum design. Doing so, we connect practice and academia through the development of actionable knowledge grounded in the empirical evaluation of how designs work in the field [10]. The process-steps where tested within several professional training programs (bachelor, postgraduate, .) in our institution.
Hydrostatic pressures effect on structure stability, electronic, optical and elastic properties of rutile VO2 doped TiO2 by density functional theory investigation

The hydrostatic pressures impact on structural stability, electronic, optical and elastic properties of Ti1−xVxO2 (x = 0, 0.25, 0.5, 0.75, 1) are studied by using the density functional theory (DFT)+U. The calculated results show that the lattice parameter, cell volume and the bond length of d Ti − O and dV−O are all decreased linearly as the concentration of V increases. As the pressure increases, these results are not changed. It is worth noting that the structure of Ti0.25V0.75O2 has the highest static refractive index n0, and Ti0.75V0.25O2 has high reflectivity at 20 GPa, respectively. The highest static refractive index n0 is 5.677 5, and the reflectivity value is 84.388% at 1.774 eV (698.98 nm). After discussion, it is concluded that the synthetic materials of Ti0.75V0.25O2 and Ti0.25V0.75O2 under the condition of 20 GPa maybe suitable as a high visible light reflective coating material and useful kind of high refractive index film materials for optical coatings, respectively.
Volatility modeling and prediction: the role of price impact

In this paper, we are interested in exploring the role of price impact, derived from the order book, in modeling and predicting stock volatility. This is motivated by the market microstructure literature that examines the mechanics of price formation and its relevance to market quality. Using a comprehensive dataset of intraday bids, asks, and three levels of market depths for 148 stocks in the Shanghai Stock Exchange from 2005 to 2016, we find substantial intraday impact from incoming bid and ask limit and market orders on stock prices. More importantly, the permanent price impact at the daily level is a significant determinant of stock volatility dynamics as suggested by the panel VAR estimation. Furthermore, when we augment traditional volatility models with the time series of daily price impact, the augmented models produce significantly more accurate volatility predictions at the one-day ahead forecasting horizon. These volatility predictions also offer economic gains to a mean-variance utility investor in a portfolio setting.
Optical gain beyond Hakki-Paoli. a new power tool for reliability of laser diodes

Simpler procedures for gain measurements in commercial laser diodes are introduced. They fully agree with the results of the popular Hakki-Paoli method, greatly extend its application range and remove those practical constraints that reserve practical gain measurement to the sole device designer and manufacturer. The aim of the paper is to propose the new method for reliability studies, to support and address the investigation of Failure Physics of semiconductor lasers. Some recent puzzling case histories are also summarized, that did not benefit of the new method. Their role is to point out how many unsuspected, and even unexplained physical phenomena may affect a technology that is not yet really assessed.
FDI, Institutional Quality, and Bribery: An Empirical Examination in China

This study attempts to identify the key factors inhibiting the bribery practices of multinational enterprise (MNE) subsidiaries directed at local managers in China. During the experiment, this study employs an institutional theory, identifies primary determinants on the phenomenon, and compares the main components between old versus young subsidiaries. Data were collected through a questionnaire survey and both regression and spearman rank order correlation analyses were used as statistical techniques. Through the analyses, we found that a cognitive pillar is a crucial element contributing to the inhibition of bribery practices, the enhancement of institutional quality, and the promotion of sustainable development in the emerging economy. We expect that the results will provide useful implications for MNE managers planning to invest in China and for policy makers enacting institutional environments.
Operating in a Constricted Space: Policy Actor Perceptions of Targeting to Address U.S. Health Disparities

Policy actors design and implement targeted interventions to eliminate disparities that exist between groups. Although necessary for achieving health equity, the use of targeting as a policy tool carries the potential for political backlash and social debate, which may influence whether and how policy actors use it. In this research, the authors examine policy actor perceptions regarding the use of targeting in the implementation of health policy. The authors conduct elite interviews with policy actors to better understand their work to design and implement interventions to address health disparities. Findings identify key tensions and trade-offs faced by policy actors related to targeting and reveal sociopolitical influences that shape whether and how targeted programs are considered, who receives them, and by what means they are delivered. The authors discuss the implications of the findings for the use of targeting and related marketing practices by policy actors to address health disparities and other significant public health concerns.

The Impact of Guilt on Interpersonal Relationships

Title of Thesis: THE IMPACT OF GUILT ON INTERPERSONAL RELATIONSHIPS Nadya G. Teneva, Master of Science, 2019 Thesis Directed By: Associate Professor, Edward P. Lemay Jr., Department of Psychology People feel guilt when they harm others. Research on guilt has found its mixed effects on interpersonal relationships. The current dyadic study investigates the primary hypothesis that two facets of guilt expression: sharing repair motivations and elaborating on transgression details, have offsetting effects on outcomes through their influence on victim’s perceptions. Perpetrators described an incident in which they expressed guilt to a partner (victims), and both parties completed measures regarding the incident. Results suggest that perpetrators who feel guilty expressed more repair motivations and more wrongdoing, and victims’ perceptions of the incident were connected to personal and relational outcomes. However, victims and perpetrators did not agree on perpetrators’ expressions of wrongdoing or repair motivation, suggesting that guilt may often have weak or mixed effects because it is not always accurately detected. In addition, several moderators of the links between guilt, guilt expression, and victims’ perceptions of the conflict were identified. THE IMPACT OF GUILT ON INTERPERSONAL RELATIONSHIPS
Evidence of early deglaciation (18 000 cal a bp) and a postglacial relative sea‐level curve from southern Karmøy, south‐west Norway

Based on six consistent radiocarbon dates from the isolation basins Grødheimsvatnet and Kringlemyr, we estimate a minimum deglaciation age for southern Karmøy, an island in outer Boknafjorden (south‐west Norway), of around 18 000 calibrated years before present (18k cal a bp). We use microscopic phytoplankton, macrofossils, lithostratigraphic evidence and X‐ray fluorescence data to identify the isolation contacts in the basins, and date them to 17.52–17.18k cal a bp in Grødheimsvatnet [15.57 m above present mean sea level (MSL)] and 16.19–15.80k cal a bp in Kringlemyr (11.99 m above MSL). Combining these data with previous studies, we construct a relative sea‐level (RSL) curve from 18k cal a bp until the present, which is ~3 ka longer than any previous RSL reconstruction from southern Norway. Following deglaciation, southern Karmøy has experienced a net emergence of around 16–19 m, although with significant RSL fluctuations. This includes two RSL minima well below present MSL around ~13.8 and ~10k cal a bp, and two maxima that culminated around 5–7 m above MSL during the Younger Dryas and early to mid‐Holocene, respectively. Considering eustatic sea level and modelled gravitational deformation of the geoid, we estimate a net postglacial isostatic uplift of ~120 m. © 2019 John Wiley & Sons, Ltd
Exploration of Class and Political Behavior in Croatia

In Western European countries, studies on the relationship between class position and political outlooks so far have a limited understanding of the relevance of class analysis, while in semiperipheral countries, like Croatia, research on class-related mechanisms and political behavior is modest, with a clear deficit of empirical research. The main goal of class analysis is to have the potential to explain various life outcomes primarily through explaining and exploring relationships between class position and life chances. In this article, we have employed neo-Weberian class analysis with the purpose to explore the relationship between class position and political behavior. In the article we use the concept of political behavior as a broader term that consists of individuals’ interest in politics, political efficacy, and political participation (voter turnout). We have used the data from the International Social Survey Program module Role of Government V from 2016. Analysis has shown that in Croatia, class membership is a predictor of interest in politics and political efficacy, i.e., that the members of a higher class show greater interest in politics and assess that they have a better understanding of politics. Class per se does not have a direct effect on voter turnout, but it is mediated through political efficacy and interest in politics since voting is mostly under the influence of personal interest in politics.
Filter Coatings Based on Combination of Nanomaterials for Steel Melt Filtration

Carbon‐bonded alumina foam filters are coated using special slurries based on graphene oxide (GO), carbon nanotubes (CNTs), and alumina nanosheets. The aim of such filters is to reduce the concentration of nonmetallic inclusions in the steel melt prior to casting into the molds. To assess the purification efficiency of the coated filters, a steel casting simulator is used. After immersion for a short time into steel melts with artificially generated alumina impurities, the filters are analyzed by optical microscopy and scanning electron microscopy. In addition, the population of remaining inclusions in the treated steel is investigated by the means of a special scanning electron microscope. The results show that, compared with a reference melt where no filter is used, the nanocoated filters cause inclusion growth and the formation of new silicate inclusions. The best purification efficiency, regarding only alumina inclusions, is given by the GO–C sample, whereas the combination of GO with alumina nanosheets or CNTs deliver worse performance.
Hindcasting Magma Reservoir Stability Preceding the 2008 Eruption of Okmok, Alaska

Volcanic eruptions pose a significant and sometimes unpredictable hazard, especially at systems that display little to no precursory signals. For example, the 2008 eruption of Okmok volcano in Alaska notably lacked observable short‐term precursors despite years of low‐level unrest. This unpredictability highlights that direct monitoring alone is not always enough to reliably forecast eruptions. In this study, we use the Ensemble Kalman Filter (EnKF) to produce a successful hindcast of the Okmok magma system in the lead up to its 2008 eruption. By assimilating geodetic observations of ground deformation, finite element models track the evolving stress state of the magma system and evaluate its stability using mechanical failure criteria. The hindcast successfully indicates an increased eruption likelihood due to tensile failure weeks in advance of the 2008 eruption. The effectiveness of this hindcast illustrates that EnKF‐based forecasting methods may provide critical information on eruption probability in systems lacking obvious precursors.

Manufacturing and qualification of the QM mirror for the high-resolution spectrometer of the FLEX mission

FLORIS (FLuorescence Imaging Spectrometer) is the single High-Resolution Spectrometer instrument of the FLEX (FLuorescence EXplorer) mission, currently under development by the European Space Agency as the eighth Earth Explorer Mission. The goal of the mission is the monitoring of the chlorophyll fluorescence of plants giving information about their photosynthetic activity. Leonardo Avionics & Space System Division is the prime contractor for the FLORIS Instrument for which Media Lario is manufacturing the QM unit of the spherical mirror included in the High-Resolution Spectrometer (HRSPE), hereafter called HRM mirror. The High-Resolution Mirror is a 250-mm diameter spherical mirror with a radius of curvature of approximately 440 mm. For the mirror substrate, Leonardo has selected the Aluminium alloy AlSi40, a special alloy with 40% Silicon content, coated with a hard polishing layer of Nickel Phosphorus (NiP), deposited by electroless chemical process. The Silicon content allows this special Aluminium alloy to have the same coefficient of thermal expansion (CTE) of the NiP layer, therefore preventing thermal deformations deriving from the bimetallic effect. The mirror structure is light-weighted to approximately 2.8 kg. The required wave-front error of the mirror is better than 0.5 fringes PV, while the surface microroughness has been specified at 0.5 nm RMS due to stringent straylight requirements of the FLORIS instrument. Media Lario has been selected for the mirror development phase because of their experience in the design and manufacturing of AlSi/NiP mirrors demonstrated in the development of the Earth Observation optical payload for small satellites (called STREEGO), based on an AlSi40 TMA telescope. The manufacturing process includes precision diamond turning, optical figuring and super-polishing. The optical coating will be done by Leonardo at their thin-films facility of Carsoli, Italy. Since the recipe prescribes to pre-heat the mirror surface at 100° C, Media Lario will qualify the mirror substrate with -25/+110°C thermal cycles to ensure adequate thermal stability for the coating process.
