The Role of Ventral Striatal Dopamine in Reward Valuation Sensitivity
Creators: name: Oppler, Scott Hunter
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Striatal dopamine (DA) has been extensively implicated in reward related processes. We assessed striatal DA variations and delay discounting (DD) behavior in humans by investigating two functional polymorphisms in genes associated with striatal DA signaling. First, the DA transporter (DAT), which is the primary mediator of DA clearance in the striatum; a variable nucleotide repeat polymorphism in the DAT gene is associated with variation in DAT expression, with the 9 repeat variant yielding greater DAT expression relative to longer repeats. Second, a single nucleotide polymorphism in the DA D2 receptor (DRD2) gene linked to variation in striatal DRD2 availability, with the “T” variant showing greater DRD2 availability relative to “C” variants. We assessed intertemporal monetary reward choice behavior using a DD task and investigated whether these genetic variations could account for significant inter-individual variance in DD behavior. Among emerging adults (ages 18-25), we observed a significant DAT×DRD2 interaction effect on the sensitivity of intertemporal choice to reward magnitude that followed an inverted U-shaped function of genetically predicted tonic striatal DA. Those with genetically predicted intermediate DA showed greater reward sensitivity relative to those with predicted high and low DA phenotypes. These results suggest that striatal DA signaling modulates reward-related decision-making in emerging adults.

description: We present photometric redshift estimates for galaxies used in the weak lensing analysis of the Dark Energy Survey Science Verification (DES SV) data. Four model- or machine learning-based photometric redshift methods -- ANNZ2, BPZ calibrated against BCC-Ufig simulations, SkyNet, and TPZ -- are analysed. For training, calibration, and testing of these methods, we construct a catalogue of spectroscopically confirmed galaxies matched against DES SV data. The performance of the methods is evaluated against the matched spectroscopic catalogue, focusing on metrics relevant for weak lensing analyses, with additional validation against COSMOS photo-zs. From the galaxies in the DES SV shear catalogue, which have mean redshift $0.72\pm0.01$ over the range $0.3

description: The multiferroic compound CuO exhibits low temperature magnetic properties similar to antiferromagnetic iron oxides, while the electronic properties have much more in common with the high $T_c$ cuprate superconductors. This suggests novel possibilities for the ultrafast optical excitation of magnetism. On the basis on atomistic spin dynamics simulations, we study the effect of phonon-assisted multimagnon absorption and photodoping on the spin dynamics in the vicinity of the first-order phase transition from collinear to spin-spiral magnetic order. Similar as in recent experiments, we find that for both excitations the phase transition can proceed on the picosecond timescale. Interestingly, however, these excitation mechanisms display very distinct dynamics. Following photodoping, the spin system first cools down on sub-ps timescales, which we explain as an ultrafast magnetocaloric effect. Opposed to this, following phonon-assisted multimagnon excitation the spin systems rapidly heats up and subsequently evolves to the noncollinear phase even under the influence of isotropic exchange interactions alone.

description: The European Virtual Observatory Euro-VO has been coordinating European VO activities through a series of projects co-funded by the European Commission over the last 15 years. The bulk of VO work in Europe is ensured by the national VO initiatives and those of intergovernmental agencies. VO activities at the European level coordinate the work in support of the three "pillars" of the Virtual Observatory: support to the scientific community, take-up by the data providers, and technological activities. Several Euro-VO projects have also provided direct support to selected developments and prototyping. This paper explains the methodology used by Euro-VO over the years. It summarizes the activities which were performed and their evolutions at different stages of the development of the VO, explains the Euro-VO role with respect to the international and national levels of VO activities, details the lessons learnt for best practices for the coordination of the VO building blocks, and the liaison with other European initiatives, documenting the added-value of European coordination. Finally, the current status and next steps of Euro-VO are briefly addressed.

description: The QCD corrections to electroweak parameters depend on the renormalization scheme and scales used to define the top-quark mass. We analyze these dependences for the W-boson mass predicted via Delta r to O(alpha alpha_s) and O(alpha alpha_s^2) in the on-shell and MS-bar schemes. These variations provide us with a hint on the magnitude of the unknown higher-order QCD effects and contribute to the theoretical error of the prediction.
Rethinking Archetypal Branding: Investigating the Effects of Authenticity and Flawed Archetypes on Brand Attachment, Self-Congruence and Purchase Intent
Creators: name: Roberts, Paige
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This thesis examines and explores the effect of the inclusion of authenticity and flaws in Jungian archetypal advertising on consumer self-congruence, brand attachment, and purchase intent. I quantitatively examine whether the introduction and exploitation of "humanistic" flaws related to a brand's existing hero archetype can enable a brand to achieve an increased actual self-brand congruence or increased brand attachment, potentially leading to increased purchase intent. I used two surveys to quantitatively examine the impact of authenticity and flaws in hero archetype advertising on brand attachment, self-congruence and purchase intent among a convenience sample of Millennial college students, primarily aged 18-24, to help explore and understand the resonance of archetypal advertising techniques with Millennial (18-34 year-old) consumers and determine whether authenticity allows archetypal branding to resonate on a deeper level with Millennials. By assessing the impact of the inclusion of authenticity and flaws on Jungian archetypal advertising, I define its potential effectiveness in strengthening brand attachment and purchase intent, and discuss implications for future archetypal advertising and branding efforts.
Protecting the Peace Without Protecting Civilians: The UN Capstone Doctrine and the Prevention of Genocide
Creators: name: Gombar, Alexandra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Perhaps the most shocking aspect of both the Rwandan and Bosnian genocides is not simply that such large-scale violence could occur, but that it could occur under the direct watch of United Nations peacekeeping forces, prompting several questions. Why did UNAMIR and UNPROFOR fail to protect the targets of genocide and ethnic cleansing? Was it due to factors specific to their staff, to the conflicts themselves or to the state of international politics in the 1990s? Or rather, did UNAMIR and UNPROFOR fail because of factors inherent to the UN system that would preclude almost any mission from being successful?
Careful analysis of UN doctrine as expressed in its official documents; the memoirs of UN officials, including UNAMIR and UNPROFOR commanders; and the work of peacekeeping, UN and genocide scholars suggests that the failure of UNAMIR and UNPROFOR to effectively address the Rwandan and Bosnian genocides were not isolated instances. Rather, I argue that these failures were the result of systemic problems within UN peacekeeping, including the Capstone Doctrine, which enshrines the principles of consent, impartiality and non-use of force as the guiding values of peacekeeping. Complications with these principles were exacerbated by wider problems within the UN system, including its access to resources; bureaucratic inefficiencies related to disputes between UN officials, communications and resource allocation; and politics within the UN Security Council (UNSC), which made member states reluctant to commit adequate troops and resources to peacekeeping missions.

description: We show that a decorated knot concordance $C$ from $K$ to $K'$ induces a homomorphism $F_C$ on knot Floer homology that preserves the Alexander and Maslov gradings. Furthermore, it induces a morphism of the spectral sequences to $\widehat{HF}(S^3) \cong \mathbb{Z}_2$ that agrees with $F_C$ on the $E^1$ page and is the identity on the $E^\infty$ page. It follows that $F_C$ is non-vanishing on $\widehat{HFK}_0(K, τ(K))$. We also obtain an invariant of slice disks in homology 4-balls bounding $S^3$. If $C$ is invertible, then $F_C$ is injective, hence $\dim \widehat{HFK}_j(K,i) \le \dim \widehat{HFK}_j(K',i)$ for every $i$, $j \in \mathbb{Z}$. This implies an unpublished result of Ruberman that if there is an invertible concordance from the knot $K$ to $K'$, then $g(K) \le g(K')$, where $g$ denotes the Seifert genus. Furthermore, if $g(K) = g(K')$ and $K'$ is fibred, then so is $K$.

description: The evolution and escape of the martian atmosphere and the planet's water inventory can be separated into an early and late evolutionary epoch. The first epoch started from the planet's origin and lasted $\sim$500 Myr. Because of the high EUV flux of the young Sun and Mars' low gravity it was accompanied by hydrodynamic blow-off of hydrogen and strong thermal escape rates of dragged heavier species such as O and C atoms. After the main part of the protoatmosphere was lost, impact-related volatiles and mantle outgassing may have resulted in accumulation of a secondary CO$_2$ atmosphere of a few tens to a few hundred mbar around $\sim$4--4.3 Gyr ago. The evolution of the atmospheric surface pressure and water inventory of such a secondary atmosphere during the second epoch which lasted from the end of the Noachian until today was most likely determined by a complex interplay of various nonthermal atmospheric escape processes, impacts, carbonate precipitation, and serpentinization during the Hesperian and Amazonian epochs which led to the present day surface pressure.

description: Background: International research has established that children and adolescents are at high risk for being exposed to violence. A systematic review published in 2023 recommended six child and adolescent self-report violence against children (VAC) measures, based on their psychometric properties, in a systematic COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) review. However, the degree of overlap and heterogeneity was not part of the analysis. Objective: To compare the six measures with respect to item overlap and differences concerning specification of exposure dimensions. Method: A content analysis of the original 174 items resulted in a reduction to 38 unique items. These items were organized visually in a co-occurrence circle using an adapted version of Fried’s R code. Furthermore, a pairwise comparison of event lists was performed using the Jaccard index. Results: There was a modest overlap among the six measures. Only one item was present in all six measures, only two items were present in four measures, and 78% of the items were present in just one or two measures. The overall overlap between the six measures was 25%. Conclusions: The lack of overlap among measures reflects a heterogeneity of definitions and purposes. It also impedes progress in research, as comparisons between various studies are difficult to make in a valid and reliable way. The lack of consensus also delays efficient political initiatives, because solid, consensual knowledge about the prevalence of VAC does not exist. Violence against children (VAC) is a high political and professional priority. A recent systematic review recommended six self-report measures based on their psychometric qualities.The VAC items were very diverse. A content analysis reduced the original 174 items to 38 unique items. A Jaccard index showed an overlap of 25%.The lack of consensus in definitions and applied measures impedes progress in research and delays important political, prophylactic initiatives.

The Hidden Power of Superheroes: The Ability of Superhero Movies to Influence Political Attitudes

Year: 2018

description: Although the literature on superheroes has expanded in recent years, it has neglected to examine whether superhero movies can affect political views. This oversight is regrettable given the recent surge in the popularity of superhero movies that engage directly with political issues such as The Dark Knight (2008), Iron Man 3 (2013), and Captain America: Civil War (2016). After a lengthy historical exploration of superheroes and a thematic analysis of these superhero movies – which collectively demonstrate that superheroes are an enduring cultural phenomenon as well as provide the theoretical underpinnings of their ability to effect attitudinal change – this study used a two-wave panel experiment to evaluate the extent to which superhero movies could cause attitudinal change. Ultimately, this study found that a significant percentage of participants changed their views on various policies related to the war on terror including torture, mass surveillance, military spending, and foreign intervention as a result of watching these superhero movies. These findings demonstrate that further research in this area is essential, particularly so long as superhero movies continue to receive critical and popular acclaim.
Religion & the Dictator Game Online Study

Year: 2022

description: Does religion promote prosocial behaviour? Despite numerous publications that seem to answer this question affirmatively, divergent results from recent meta-analyses and pre-registered replication efforts suggest the issue is not yet settled. Additional uncertainty lingers around whether (a) the effects of religious cognition on prosocial behaviour obtain through implicit cognitive processes, explicit cognitive processes, or both; and (b) whether religious cognition increases generosity only among people disinclined to share with anonymous strangers. Here we propose two experiments designed to address these concerns. In Experiment 1 we will seek to replicate Shariff and Norenzayan’s demonstration of the effects of implicit religious priming on Dictator Game offers to anonymous strangers; unlike Shariff and Norenzayan, however, we will use an online environment where anonymity is virtually assured. In Experiment 2, we will introduce a “taking” option to allow greater expression of baseline selfishness. In both experiments, we will seek to activate religious cognition implicitly and explicitly. Finally, we will use multiple methods to meta-analyse all available experiments that test the effect of religious priming on Dictator Game transfers. Our results will provide new insight into an important interdisciplinary issue, and guidance on how best to activate religious cognition in the laboratory.

description: A vast literature on the theory and phenomenology of Two-Higgs-Doublet models (2HDM) exists since long. However, the present situation demands a revisit of some 2HDM properties. Now that a 125 GeV scalar resonance has been discovered at the LHC, with its couplings to other particles showing increasing affinity to the Standard Model Higgs-like behavior, the 2HDM parameter space is more squeezed than ever. We briefly review the different parametrizations of the 2HDM potential and discuss the constraints on the parameter space arising from the unitarity and stability of the potential together with constraints from the oblique electroweak $T$-parameter. We also differentiate the consequences of imposing a global continuous U(1) symmetry on the potential from a discrete $Z_2$ symmetry.

description: EBV was the first human oncogenic virus identified. It was discovered in tumour cells isolated from Burkitt’s lymphoma tissue by Sir Anthony Epstein and Dr Yvonne Barr in 1964. Some years after its discovery, EBV was shown to be able to transform normal leukocytes into lymphoblastoid cell lines (LCLs). Since then, EBV has been found to be associated with many malignancies originating from lymphocytes or epithelial cells (Burkitt’s lymphoma, post-transplant and HIV-associated lymphomas, Hodgkin’s lymphoma, T-cell lymphoma, extra-nodal nasal-type natural killer/T-cell lymphoma, nasopharyngeal cancer, and a subset of gastric cancers), contributing to 1.5% of all cancer cases worldwide and approximately 200,000 new cases every year. However, this virus is found in more than 90% of healthy adults worldwide, indicating that EBV infection alone is not enough to cause cancer. The specific geographical distribution of some EBV-associated malignancies (such as Burkitt’s lymphoma in equatorial Africa and nasopharyngeal cancer in East Asia) indicates that the development of an EBV-associated neoplasm requires different environmental and genetic co-factors, of which only some are currently known. In this Special Issue, we present a collection of 26 papers (9 research papers and 17 reviews) covering a range of topics related to EBV infection in cancer patients. These fall into three general areas: (1) EBV-encoded genes; (2) EBV and immune responses; and (3) EBV-associated malignancies and EBV-targeted therapies. In this Special Issue, we aim to further elucidate the role of EBV infection in EBV-driven malignancies by reviewing the literature and reporting new findings addressing some of the unanswered questions in the field of EBV

description: Inclusion of spin-dependent interactions in graphene in the vicinity of the Dirac points can be posed in terms of non-Abelian gauge potentials. Such gauge potentials being surrogates of physical electric fields and material parameters, only enjoy a limited gauge freedom. A general gauge transformation thus in general changes the physical model. We argue that this property can be useful in connecting reference physical situations, such as free particle or Rashba interactions to non-trivial physical Hamiltonians with a new set of spin-orbit interactions, albeit constrained to being isoenergetic. We analyse different combinations of spin-orbit interactions in the case of monolayer graphene and show how they are related by means of selected non-Abelian gauge transformations.

description: Motivated by recent experiments probing anomalous surface states of Dirac semimetals (DSMs) Na$_3$Bi and Cd$_3$As$_2$, we raise the question posed in the title. We find that, in marked contrast to Weyl semimetals, the gapless surface states of DSMs are not topologically protected in general, except on time-reversal-invariant planes of surface Brillouin zone. We first demonstrate this in a minimal $4$-band model with a pair of Dirac nodes at ${\bf k}=(0,0,\pm Q)$, where gapless states on the side surfaces are protected only near $k_z=0$. We then validate our conclusions about the absence of a topological invariant protecting double Fermi arcs in DSMs using a K-theory analysis for space groups of Na$_3$Bi and Cd$_3$As$_2$. Generically, the arcs deform into a Fermi pocket, similar to {the surface states of a topological insulator (TI), and this can merge into the} projection of bulk Dirac Fermi surfaces as the chemical potential is varied. We make sharp predictions for the doping-dependence of the surface states of a DSM that can be tested by ARPES and quantum oscillation experiments.

description: The common colon cancer drug CPT-11 and its active metabolite SN-38 have a dose-limiting side effect of severe diarrhea in patients. The dose-limiting side effects of CPT-11 arise when the metabolite SN-38G is reactivated in the intestines by β-glucuronidases (GUS) from bacteria. Previous work found selective inhibitors that bind to a loop region near the active site in different species and are effective in alleviating CPT-11 induced diarrhea in mice. The GUS from Bacteroides dorei does not have this loop. We sought to kinetically characterize the processing of SN-38G by this GUS and compare it with other GUS enzymes from common bacteria. We found that GUS from B. dorei was less effective than enzymes from other bacteria, however it did process SN-38G with a Km of 21±2 μM and a kcat of 5.9±0.2 s-1. Therefore, new inhibitors may need to be designed that do not require an active site loop for have maximal chemotherapeutic effectiveness against CPT-11 induced diarrhea. We also attempted to characterize the response and growth of Escherichia coli in the glucuronidated forms of Diclofenac and estriol. From this, we determined that higher than 25 μM and 100 nM of substrate, respectively are necessary to maintain growth.

After Sr doping, the Fermi level was found to move further upwards when compared with the parent compound Bi2Se3, which is consistent with the low carrier density in this system. The topological surface state was clearly observed, and the position of the Dirac point was determined in all doped samples. The surface state is well separated from the bulk conduction bands in the momentum space. The persistence of separated topological surface state combined with small Fermi energy makes this superconducting material a very promising candidate for the time reversal invariant topological superconductor

description: The existence of abortion counseling and therapeutic assistance with pregnancy decision-making is a relatively novel development, growing out of a particular cultural and political context in the United States. This thesis examines the ways that America’s “self-help therapeutic culture” is impacting the meanings of abortion in both the public and private spheres. Qualitative analysis of archival counseling resources and of semi-structured interviews with pro-life and pro-choice professionals provides insight into how therapeutic culture provides ways of undertaking support for unplanned pregnancies. These approaches are reshaping on-the-ground abortion politics by creating new grounds for claims-making. This thesis has begun to explore the kinds of political implications that therapeutic culture has as it is intertwined with pregnancy decision-making services.

description: In a multi-input-multi-output (MIMO) communication system there is a necessity to limit the power that the output antenna amplifiers can deliver. Their signal is a combination of many independent channels, so the demanded amplitude can peak to many times the average value. The orthogonal frequency division multiplexing (OFDM) system causes high peak signals to occur because many subcarrier components are added by an inverse discrete Fourier transformation process at the base station. This causes out-of-band spectral regrowth. If simple clipping of the input signal is used, there will be in-band distortions in the transmitted signals and the bit error rate will increase substantially. This work presents a novel technique that reduces the peak-to-average power ratio (PAPR). It is a combination of two main stages, a variable clipping level and an Adaptive Optimizer that takes advantage of the channel state information sent from all users in the cell. Simulation results show that the proposed method achieves a better overall system performance than that of conventional peak reduction systems in terms of the symbol error rate. As a result, the linear output of the power amplifiers can be minimized with a great saving in cost.
Investigating the Role of FoxA1 and FoxA2 as Candidate Transcriptional Regulators of Sox9 in Intestinal Crypt Stem Cells

description: Two stem cell states have been identified within the crypts of the small intestine: ‘quiescent’ and ‘active’. SOX9, a transcription factor encoded from the Sox9 gene has been hypothesized to be the master regulator between these ‘active’ (low expression of SOX9) and ‘reserve’ (high expression of SOX9) intestinal stem cell states. Therefore, putative cis-regulatory sequences upstream of the SOX9 promoter have been analyzed through TRANSFAC© to determine potential candidates for up-regulation of SOX9 in quiescent and active stem cells. Preliminary results indicate that FOXA1and A2 represent potential transcriptional regulators of the SOX9 gene. This hypothesis has been supported by immunohistochemistry, qRT-PCR analysis, and ChIP-sequencing demonstrating that FOXA1/2 co-expresses in cells that express high levels of SOX9 within the intestinal crypt. These studies provide further understanding of how stem cell identity is normally regulated in the cells of the intestinal crypt.

description: Foam concrete has attracted attention worldwide because of its light weight and enhanced insulating properties as a building material. Pore features in foam concrete play an important role in affecting its compressive strength and insulation properties. Therefore, quantitative description of relationships between pore features heat conductivity and compressive strength is the main aims of this thesis. To accomplish the aims, theoretical method is employed to deduce the heat conductivity, and experimental method is used to justify its compressive. Further, Matlab and Python program are programmed to depict the random pore distribution, and then finite element method is employed to calculate its compressive based on the pore distribution.

description: We present preliminary results of the spectral analysis on the radial distributions of the star formation history in both, a galaxy merger and a spiral isolated galaxy observed with MaNGA. We find that the central part of the isolated galaxy is composed by older stellar population ($\sim$2 Gyr) than in the outskirts ($\sim$7 Gyr). Also, the time-scale is gradually larger from 1 Gyr in the inner part to 3 Gyr in the outer regions of the galaxy. In the case of the merger, the stellar population in the central region is older than in the tails, presenting a longer time-scale in comparison to central part in the isolated galaxy. Our results are in agreement with a scenario where spiral galaxies are built from inside-out. In the case of the merger, we find evidence that interactions enhance star formation in the central part of the galaxy.

description: Antibiotics are used in food animal husbandry in the United States for the treatment and prevention of disease and for growth promotion. Our aim was to study the potential effects of antibiotic use in animal husbandry. We isolated Staphylococcus aureus from the heads (mouth and nares) of recently-slaughtered hogs in order to compare antibiotic resistance profiles of hogs raised without antibiotics (RWA; N=115 isolates) to those raised with antibiotics, conventionally raised (CR; N=98 isolates). All hog products were obtained from the same slaughterhouse, limiting exposure differences in the hogs after leaving their respective operations. We found overall higher proportions of resistance in tested CR hog isolates than tested RWA hog isolates. A significantly higher proportion of multidrug-resistant S. aureus isolates were found from CR hogs than from RWA hogs (92% and 7.0%, respectively, p<0.0001). Additionally, CR hog isolates were significantly more often resistant to antibiotic classes sold and distributed mostly for food animals (98% in CR; 7% in RWA, p<0.0001). These findings suggest a relationship between the use of antibiotics in food animals and antibiotic resistance. This is the first study to compare S. aureus communities in recently-slaughtered hogs processed in the same slaughterhouse, but raised in different environments of antibiotic use (RWA vs. CR), in North Carolina.

Σε αυτό το πρόβλημα η αποθήκη η οποία δεν έχει ιδιόκτητο στόλο οχημάτων, νοικιάζει οχήματα προκειμένου να παραδώσει τα προϊόντα στους πελάτες. Μετά την ολοκλήρωση των παραδόσεων τα οχήματα δεν επιστρέφουν στην αποθήκη.

description: The use of annotations, referred to as assertions or contracts, to describe program properties for which run-time tests are to be generated, has become frequent in dynamic programing languages. However, the frameworks proposed to support such run-time testing generally incur high time and/or space overheads over standard program execution. We present an approach for reducing this overhead that is based on the use of memoization to cache intermediate results of check evaluation, avoiding repeated checking of previously verified properties. Compared to approaches that reduce checking frequency, our proposal has the advantage of being exhaustive (i.e., all tests are checked at all points) while still being much more efficient than standard run-time checking. Compared to the limited previous work on memoization, it performs the task without requiring modifications to data structure representation or checking code. While the approach is general and system-independent, we present it for concreteness in the context of the Ciao run-time checking framework, which allows us to provide an operational semantics with checks and caching. We also report on a prototype implementation and provide some experimental results that support that using a relatively small cache leads to significant decreases in run-time checking overhead.

The attentional boost effect of memory across modalities: Is the attentional boost effect caused by enhanced perceptual processing?
Creators: name: O'Toole, Allison
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: The attentional boost effect (ABE) refers to a phenomenon in which the usual inhibitory effects of divided attention are overcome, and the divided attention (DA) conditions perform just as well on tests of memory as the full attention (FA) conditions. This effect occurs when participants in the divided attention condition are required to monitor a distracter item and respond to its change. The perceptual encoding hypothesis states that this enhancement in memory is due to an increase in perceptual processing during encoding due to the nature of the distracter task (Swallow & Jiang, 2010, 2011, 2012). This study contains two experiments that provide evidence against the perceptual encoding hypotheses in the ABE using a crossed modality manipulation in recognition and free recall. Other explanations are considered.

description: K2-19 (EPIC201505350) is an interesting planetary system in which two transiting planets with radii ~ 7 $R_{Earth}$ (inner planet b) and ~ 4 $R_{Earth}$ (outer planet c) have orbits that are nearly in a 3:2 mean-motion resonance. Here, we present results of ground-based follow-up observations for the K2-19 planetary system. We have performed high-dispersion spectroscopy and high-contrast adaptive-optics imaging of the host star with the HDS and HiCIAO on the Subaru 8.2m telescope. We find that the host star is relatively old (>8 Gyr) late G-type star ($T_{eff}$ ~ 5350 K, $M_s$ ~ 0.9 $M_{Sun}$, and $R_{s}$ ~ 0.9 $R_{Sun}$). We do not find any contaminating faint objects near the host star which could be responsible for (or dilute) the transit signals. We have also conducted transit follow-up photometry for the inner planet with KeplerCam on the FLWO 1.2m telescope, TRAPPISTCAM on the TRAPPIST 0.6m telescope, and MuSCAT on the OAO 1.88m telescope. We confirm the presence of transit-timing variations, as previously reported by Armstrong and coworkers. We model the observed transit-timing variations of the inner planet using the synodic chopping formulae given by Deck & Agol (2015). We find two statistically indistinguishable solutions for which the period ratios ($P_{c}/P_{b}$) are located slightly above and below the exact 3:2 commensurability. Despite the degeneracy, we derive the orbital period of the inner planet $P_b$ ~ 7.921 days and the mass of the outer planet $M_c$ ~ 20 $M_{Earth}$. Additional transit photometry (especially for the outer planet) as well as precise radial-velocity measurements would be helpful to break the degeneracy and to determine the mass of the inner planet.
