PERHATIAN INVESTOR DAN LIKUIDITAS SAHAM PERUSAHAAN PUBLIK DI BURSA EFEK INDONESIA

Signifikannya geliat internet di Indonesia membuat kontribusi internet (Google) sebagai media perantara penyampaian informasi ke publik menjadi sarana yang semakin diminati. Hal ini menjadi relevan karena andil internet terhadap perkembangan ekonomi Indonesia juga tercatat sebagai determinan yang penting. Oleh sebab itu, penelitian ini bermaksud menguji peran Internet yang dapat dianalogikan sebagai representasi dari perhatian investor, dan menghubungkannya dengan likuiditas saham perusahaan publik yang diperdagangkan di Bursa Efek Indonesia (BEI). Dengan menggunakan basis teori asimetri informasi, penelitian ini juga mengkaji secara empiris upaya mitigasi terhadap kesenjangan informasi antara investor terinformasi (informed) vs. investor tidak terinformasi (uninformed). Secara operasional, penelitian ini menggunakan sampel dari 82 perusahaan publik di BEI dengan periode waktu pengamatan bulanan dari bulan Januari 2013 sampai dengan Desember 2017. Dengan karakteristik dan struktur data panel, maka penelitian ini menggunakan analisis regresi panel dengan jumlah data sebesar 4,920 observasi (perusahaan-bulan). Analisis yang digunakan juga menerapkan fixed-effect model (FEM) pada level perusahaan (firm-FE) dan tahun (Month-FE), yang disertai dengan clustered SE guna mengantisipasi potensi overestimasi pada nilai standard error (SE). Hasil penelitian menunjukkan bahwa terdapat asosiasi yang positif antara perhatian investor yang diwakili oleh GSV (Google Search Volume) dengan likuiditas saham perusahaan, TV (Trading Volume). Implikasi dari temuan ini menunjukkan bahwa stakeholder (investor) dapat mempergunakan informasi publik yang tersedia dan didistribusikan melalui internet untuk mereduksi tingkat asimetri informasi yang terjadi antara informed vs. uninformed investor di pasar modal.
The Epeak – Eiso relation revisited with Fermi GRBs - Resolving a long-standing debate?

We used a sample of GRBs detected by Fermi and Swift to reanalyze the correlation discovered by Amati et al. (2002) between Epi, the peak energy of the prompt GRB emission, and Eiso, the energy released by the GRB assuming isotropic emission. This correlation has been disputed by various authors, and our aim is to assess whether it is an intrinsic GRB property or the consequence of selection effects. We constructed a sample of Fermi GRBs with homogeneous selection criteria, and we studied their distribution in the Epi-Eiso plane. Our sample is made of 43 GRBs with a redshift and 243 GRBs without a redshift. We show that GRBs with a redshift follow a broad Epi-Eiso relation, while GRBs without a redshift show several outliers. We use these samples to discuss the impact of selection effects associated with GRB detection and with redshift measurement. We find that the Epi-Eiso relation is partly due to intrinsic GRB properties and partly due to selection effects. The lower right boundary of the Epi-Eiso relation stems from a true lack of luminous GRBs with low Epi. In contrast, the upper left boundary is attributed to selection effects acting against the detection GRBs with low Eiso and large Epi that appear to have a lower signal-to-noise ratio. In addition, we demonstrate that GRBs with and without a redshift follow different distributions in the Epi-Eiso plane. GRBs with a redshift are concentrated near the lower right boundary of the Epi-Eiso relation. This suggests that it is easier to measure the redshift of GRBs close to the lower Epi-Eiso boundary. In this context, we attribute the controversy about the reality of the Amati relation to the complex nature of this relation resulting from the combination of a true physical boundary and biases favoring the detection and the measurement of the redshift of GRBs located close to this boundary.
Charged black holes in string-inspired gravity II. Mass inflation and dependence on parameters and potentials

We investigate the relation between the existence of mass inflation and model parameters of string-inspired gravity models. In order to cover various models, we investigate a Brans-Dicke theory that is coupled to a U(1) gauge field. By tuning a model parameter that decides the coupling between the Brans-Dicke field and the electromagnetic field, we can make both of models such that the Brans-Dicke field is biased toward strong or weak coupling directions after gravitational collapses. We observe that as long as the Brans-Dicke field is biased toward any (strong or weak) directions, there is no Cauchy horizon and no mass inflation. Therefore, we conclude that to induce a Cauchy horizon and mass inflation inside a charged black hole, either there is no bias of the Brans-Dicke field as well as no Brans-Dicke hair outside the horizon or such a biased Brans-Dicke field should be well trapped and controlled by a potential.
Herschel SPIRE-FTS observations of RCW 120

Context. The expansion of Galactic H II regions can trigger the formation of a new generation of stars. However, little is know about the physical conditions that prevail in these regions. Aims. We study the physical conditions that prevail in specific zones towards expanding H II regions that trace representative media such as the photodissociation region, the ionized region, and condensations with and without ongoing star formation. Methods. We use the SPIRE Fourier Transform Spectrometer (FTS) on board Herschel to observe the H II region RCW 120. Continuum and lines are observed in the 190-670 mu m range. Line intensities and line ratios are obtained and used as physical diagnostics of the gas. We used the Meudon PDR code and the RADEX code to derive the gas density and the radiation field at nine distinct positions including the PDR surface and regions with and without star-formation activity. Results. For the different regions we detect the atomic lines [NII] at 205 mu m and [CI] at 370 and 609 mu m, the (CO)-C-12 ladder between the J = 4 and J = 13 levels and the (CO)-C-13 ladder between the J = 5 and J = 14 levels, as well as CH+ in absorption. We find gas temperatures in the range 45-250 K for densities of 10(4) - 10(6) cm(-3), and a high column density on the order of N-H similar to 10(22) cm(-2) that is in agreement with dust analysis. The ubiquitousness of the atomic and CH+ emission suggests the presence of a low-density PDR throughout RCW 120. High-excitation lines of CO indicate the presence of irradiated dense structures or small dense clumps containing young stellar objects, while we also find a less dense medium (N-H similar to 10(20) cm(-2)) with high temperatures (80-200 K).
Black soliton in a quasi-one-dimensional trapped fermion-fermion mixture

Employing a time-dependent mean-field-hydrodynamic model we study the generation of black solitons in a degenerate fermion-fermion mixture in a cigar-shaped geometry using variational and numerical solutions. The black soliton is found to be the first stationary vibrational excitation of the system and is considered to be a nonlinear continuation of the vibrational excitation of the harmonic oscillator state. We illustrate the stationary nature of the black soliton, by studying different perturbations on it after its formation.
Comparative Analysis of Intravenous Ceftriaxone and Ciprofloxacin for the Treatment of Bacterial Peritonitis in Liver Cirrhosis

The Purpose of the current study to Evaluate the efficacy of intravenous ciprofloxacin with ceftriaxone for the treatment of bacterial peritonitis in patients of liver cirrhosis at PIMS Hospital Islamabad from January 2021 to June 2021 at Department of Medicine . A total of 260 patients of liver cirrhosis were selected for this study. Patients were randomly allocated in two groups (Group A and B). Patients aged 13 to 60 years of both genders with established liver cirrhosis, diagnosed on ultrasound abdomen were included in this study. Patients with hemorrhagic or malignant ascites, peritonitis, tuberculosis peritonitis, hepatocellular carcinoma and diabetes mellitus were excluded from study. In group A, 130 patients were given intravenous ciprofloxacin 200mg 12 hourly and in group B 130 patients on ceftriaxone 1g 12 hourly. Treatment was given for 5 days and efficacy of treatment was determined by means of evaluating clinical symptoms. The mean age of the patients in group A was 43.4±10.4 years and in group B was 44.2±10.2 years. In group A there were 90(70%) patients and 95(73.3%) patients in group B in whom spontaneous bacterial peritonitis was settled down. The Result of the current study suggest that Intravenous is as effective as ceftriaxone in the treatment of spontaneous bacterial peritonitis in cirrhotic patients. Keywords: liver cirrhosis, ciprofloxacin, bacterial peritonitis, ceftriaxone
Topological Data Analysis of m-Polar Spherical Fuzzy Information with LAM and SIR Models

The concept of m-polar spherical fuzzy sets (mPSFS) is a combination of m-polar fuzzy sets (mPFS) and spherical fuzzy sets (SFS). An mPSFS is an optimal strategy for addressing multipolarity and fuzziness in terms of ordered triples of positive membership grades (PMGs), negative membership grades (NMGs), and neutral grades (NGs). In this study, the innovative concept of m-polar spherical fuzzy topology (mPSF-topology) is proposed for data analysis and information aggregation. We look into the characteristics and results of mPSF-topology with the help of several examples. Topological structures on mPSFSs help with both the development of new artificial intelligence (AI) tools for different domain strategies and the study of different kinds of uncertainty in everyday life problems. These strategies make it possible to recognise and look into a situation early on, which helps professionals to reduce certain risks. In order to address various group decision-making issues in the m-polar spherical fuzzy domain, one suggestion has been to apply an extended linear assignment model (LAM) along with the SIR method known as superiority and inferiority ranking methodology in order to analyze road accident issues and dispute resolution. In addition, we examine the symmetry of optimal decision and perform a comparative study between the research carried out using the suggested methodology and several existing methods.
Effects of L-Citrulline Supplementation on Endothelial Function and Blood Pressure in Hypertensive Postmenopausal Women

Aging and menopause are associated with decreased nitric oxide bioavailability due to reduced L-arginine (L-ARG) levels contributing to endothelial dysfunction (ED). ED precedes arterial stiffness and hypertension development, a major risk factor for cardiovascular disease. This study investigated the effects of L-citrulline (L-CIT) on endothelial function, aortic stiffness, and resting brachial and aortic blood pressures (BP) in hypertensive postmenopausal women. Twenty-five postmenopausal women were randomized to 4 weeks of L-CIT (10 g) or placebo (PL). Serum L-ARG, brachial artery flow-mediated dilation (FMD), aortic stiffness (carotid-femoral pulse wave velocity, cfPWV), and resting brachial and aortic BP were assessed at 0 and 4 weeks. L-CIT supplementation increased L-ARG levels (Δ13 ± 2 vs. Δ−2 ± 2 µmol/L, p < 0.01) and FMD (Δ1.4 ± 2.0% vs. Δ−0.5 ± 1.7%, p = 0.03) compared to PL. Resting aortic diastolic BP (Δ−2 ± 4 vs. Δ2 ± 5 mmHg, p = 0.01) and mean arterial pressure (Δ−2 ± 4 vs. Δ2 ± 6 mmHg, p = 0.04) were significantly decreased after 4 weeks of L-CIT compared to PL. Although not statistically significant (p = 0.07), cfPWV decreased after L-CIT supplementation by ~0.66 m/s. These findings suggest that L-CIT supplementation improves endothelial function and aortic BP via increased L-ARG availability.
Evaluation of Cardiovascular Effects of Methylphenidate in Children with Attention-deficit Hyperactivity Disorder

Objective: In patients with attention-deficit hyperactivity disorder (ADHD), methylphenidate (MPH) treatment may lead to serious cardiac problems. Therefore, this study was undertaken to assess cardiac effects and electrocardiographic (ECG) changes regarding risks of ventricular arrhythmia occurring after initiation of MPH treatment in ADHD patients. Method: Thirty patients (mean age: 8.9±1.93 years) diagnosed with ADHD and 41 healthy subjects (mean age: 9.78±3.07 years) were included in this study blood pressures, heart rates, and ECGs of the patients were evaluated before and third month of treatment. ECG parameters including QRS, QT, corrected QT interval (QTc), QTdispersion (QTdis), Tp-Te, Tp-Te dispersion, and Tp-Te/QTc ratio were also assessed. Results: Untreated patients with ADHD and healthy subjects had similar systolic blood pressures and heart rates, although ADHD patients had higher diastolic blood pressures. An increase in heart rates, systolic and diastolic blood pressures was observed in the patient group in third month of treatment. Prior to MPH treatment, patients with ADHD and control subjects were compared in terms of ECG parameters: QRS, QT, QTc, QTdis, Tp-Te, Tp-Te dispersion, Tp-Te/QTc ratio but without any intergroup difference. Following MPH treatment, QRS, QT, QTc, QTdis did not change in the patient group but significant increases were observed in Tp-Te, Tp-Te dispersions, Tp-Te/ QTc ratios. Conclusion: Use of the MPH in ADHD patients is associated with alterations in ECG parameters, heart rates, diastolic and systolic blood pressures. Assessment of ECG parameters such as Tp-Te, Tp-Te dispersions, Tp-Te/QTc ratios may prove more beneficial for evaluating the risk of ventricular arrythmia in pediatric patients with ADHD.
Ultrasensitive nanoelectromechanical mass detection

We describe the application of nanoelectromechanical systems (NEMS) to ultrasensitive mass detection. In these experiments, a modulated flux of atoms was adsorbed upon the surface of a 32.8 MHz NEMS resonator within an ultrahigh-vacuum environment. The mass-induced resonance frequency shifts by these adsorbates were then measured to ascertain a mass sensitivity of 2.53×10^–18 g. In these initial measurements, this sensitivity is limited by the noise in the NEMS displacement transducer; the ultimate limits of the technique are set by fundamental phase noise processes. Our results and analysis indicate that mass sensing of individual molecules will be realizable with optimized NEMS devices.
Quantifying and identifying the overlapping community structure in networks

It has been shown that the communities of complex networks often overlap with each other. However, there is no effective method to quantify the overlapping community structure. In this paper, we propose a metric to address this problem. Instead of assuming that one node can only belong to one community, our metric assumes that a maximal clique only belongs to one community. In this way, the overlaps between communities are allowed. To identify the overlapping community structure, we construct a maximal clique network from the original network, and prove that the optimization of our metric on the original network is equivalent to the optimization of Newman’s modularity on the maximal clique network. Thus the overlapping community structure can be identified through partitioning the maximal clique network using any modularity optimization method. The effectiveness of our metric is demonstrated by extensive tests on both artificial networks and real world networks with a known community structure. The application to the word association network also reproduces excellent results.
Defects and Geometry in Condensed Matter Physics

This book describes the key role played by thermally excited defects such as vortices, disclinations, dislocations, vacancies and interstitials in the physics of crystals, superfluids, superconductors, liquid crystals and polymer arrays. Geometrical aspects of statistical mechanics become particularly important when thermal fluctuations entangle or crumple extended line-like or surface-like objects in three dimensions. In the case of entangled vortices above the first-order flux lattice melting transition in hightemperature superconductors, the lines themselves are defects. A variety of theories combined with renormalization-group ideas are used to describe the delicate interplay among defects, statistical mechanics and geometry characteristic of these problems in condensed matter physics. This indispensible guide has its origins in Professor Nelson’s contributions to summer schools, conference proceedings and workshops over the past twenty years. It provides a coherent and pedagogic graduate-level introduction to the field of defects and geometry.
Antibiotic Residues in Tiger Shrimp (Penaeus monodon)

Tiger shrimp (Penaeus monodon Fabricius) from Bangkok, Thailand, were examined for antibiotic residues. Samples were purchased monthly from open markets between October 1990 and October 1991. The standard four plate test was used for antibiotic detection during October 1990 through April 1991. Later on, Bacillus subtilis in peptone free media, and B. stearothermophilus were included. Overall, 8.4 per cent of the 1,461 samples tested were positive. The incidence rate of antibiotic residues each month varied from O to 37 per cent. Identification of antibiotics from 21 positive samples carried out using HPLC showed that oxolinic acid (OA) and oxytetracycline (OTC) were present in 12 and 9 samples, respectively. The concentrations of the drugs were 0.02-2.25 mg·l·1 for OA and 0.06-0.42 mg·J·1 for OTC.
Dispersion and polarization conversion of whispering gallery modes in nanowires

We investigate theoretically the optical properties of nano-wires (NWs) with cross sections having either discrete or cylindrical symmetry. The material forming the wire is birefringent, showing a different dielectric response in the plane and along the axis of the wire, which is typically the case for wires made of wurtzite materials, such as ZnO or GaN. We look for solutions of Maxwell's equations having the proper symmetry. The dispersions and the linewidths versus angle of incident light for the modes having high momentum in the cross-section plane, so called whispering gallery modes, are calculated. We put a special emphasis on the case of hexagonal cross sections. The energy positions of the modes for a set of azimuthal quantum numbers are shown. We demonstrate the dependence of the energy splitting between TE and TM modes versus birefringence. The polarization conversion from TE to TM with increase in the axial wave vector is discussed for both cylindrical and discrete symmetries.
Explaining Drivers’ Support for Tolls and their Toll Avoidance Behavior

There is growing reliance on road tolls for revenue and for highway congestion management. However, there is limited research, in the U.S. context, on how drivers change their behavior in response to tolls. But experiences in Europe and Asia find that drivers respond to tolls through a variety of behavioral shifts. Such behaviors have implications for the revenue generating capabilities of tolls as well as the effectiveness of tolls as a traffic management tool. This research applies the Theory of Planned Behavior to examine drivers’ behavioral responses to tolls. We connect a preference for tolls as a funding source, ability to pay, and perceptions of toll benefits to the support for tolls, and, subsequently, to a number of toll avoidance responses. We examine the following toll avoidance behavior: changing home or employment location; changing commute; avoiding travel to destinations that require tolls; and telecommuting or working from home. Using data from a 2014 survey of drivers in the Hampton Roads region of Virginia, conducted nine months after toll implementation, we find that a higher willingness to pay decreases the likelihood of toll avoidance behavior and that the preference for tolls over taxes and the timing of travel impact willingness to pay, as well as race of the driver. Age, gender, education, and race influence toll avoidance behavior. Our findings suggest social justice be considered when developing a toll system, especially the impact on short-term and long-term toll avoidance behaviors.
NP - 07 - O Efeito da covid-19 sobre os indicadores de pobreza brasileiros e as políticas de mitigação : uma discussão inicial

As estratégias para a erradicação da pobreza constituem o ponto de partida para a agenda de desenvolvimento socioeconômico. A razão para isso reside na importância da pobreza como um indicador de bem-estar contemporâneo de uma sociedade e de seu efeito propagador de choques adversos ao longo dos anos e entre as gerações. De uma forma mais específica, a conexão entre a pobreza atual e a futura pode se dar a partir de uma série de mecanismos. A literatura especializada reconhece que os choques adversos in utero e na primeira infância afetam os resultados econômicos (desempenho escolar, renda e saúde, por exemplo) destes mesmos indivíduos na sua vida adulta. Ademais, as condições de vida dos pais podem ser decisivas para a saúde e o desenvolvimento humano dos filhos, unindo de forma perversa as gerações. No caso brasileiro, estima-se que a pobreza dos pais constitui o principal fator de propagação de choques negativos, contribuindo para a deterioração da saúde das crianças e para o aumento na incidência do trabalho infantil, entre outros.
Optimising the K Dark Filter for the Kunlun Infrared Sky Survey

Abstract The Kunlun Infrared Sky Survey will be the first comprehensive exploration of the time varying Universe in the infrared. A key feature in optimising the scientific yield of this ambitious research programme is the choice of the survey passband. In particular, the survey aims to maximally exploit the unique thermal and atmospheric conditions pertaining to the high Antarctic site. By simulating the expected signal-to-noise for varying filter properties within the so-called ‘K DARK’ 2.4 μm window, filter performance can be tuned and best-case designs are given covering a range of conditions.
An assessment of the dietary habits among road cyclists competing in amateur races

Abstract From year to year, practicing various sports by amateur athletes is becoming more and more popular. One of such sports is road cycling. To achieve very good sports performance athletes should pay attention not only to physical activity but also to proper nutrition and hydration of the body. The aim of the study was to assess amateur cyclists' dietary habits, especially nutrition and hydration, including assessment of the regularity of eating meals, type of consuming products and fluid intake preferences. The study recruited 41 men aged 23–75 years (43.76 ± 13.25) participating in amateur race road cycling. To obtain information about nutrition and hydration, an original questionnaire was used. Out of all participants, 65.9% declared that they pay attention to their diet, and as many as 75.6% indicated that they eat meals regularly. The vast majority (43.9%) of the cyclists declared consuming four meals a day. Most of the cyclists consumed meat products several times a week—73.2% and dairy products—43.9%. The participants most often chose only one portion of fruit (41.5%) and vegetables (31.7%) during the day. The vast majority of cyclists consumed 3 L of fluids on a training day—51.2%. It turned out that all of the athletes hydrated during training: before it was 68.3% and after training—92.7%. We conclude that the amateur cyclists pay a lot of attention to their nutrition and hydration. During the day, most athletes eat an appropriate amount of meals on a regular basis and drink the right amount of fluids. However, eating of dairy, fruits and vegetables, or hydrating before exercising is insufficient.
