Ideal-perception consistency and regulation of best friends: Associations With attachment anxiety and avoidance

Do people use ideal standards to evaluate and regulate their best friends? The current research examines whether the Ideal Standards Model captures dynamics in friendships, and what role attachment orientations play in these dynamics. Greater discrepancies between perceptions of best friends and ideal standards (low ideal-perception consistency) on the warmth/trustworthiness (Studies 1–3) and status/resources (Study 2) dimensions were associated with greater regulation attempts of best friends on these dimensions. Low ideal-perception consistency on the attractiveness/vitality dimension was not associated with regulation on this dimension (Study 2). Additionally, all studies illustrated that attachment avoidance was associated with lower ideal-perception consistency and, in turn, greater regulation attempts. By contrast, attachment anxiety was associated with higher regulation attempts of best friends, not because of lower ideal-perception consistency, but because of greater relationship maintenance motivations (Study 2) and an acute sensitivity to daily reductions in ideal-perception consistency (Study 3).

Analyzing the Mediating Effect of Psychological Resilience on the Relationship between COVID-19 Fear and Happiness

Background / purpose – Psychological resilience is considered a factor that can support teachers’ adaptation to rapidly changing situations such as COVID-19, and in turn help to reduce the fear they may experience. The current study aims to examine the effect of COVID19 fear on happiness through the mediating effect of psychological resilience based on teachers' perceptions. Materials / methods – The study was designed according to the relational survey model, and was conducted with the participation of 346 teachers. Research data were collected through online surveys. The study used the Sobel, Aroian, and Goodman tests to test the significance of the effect of the mediator variables between the dependent and independent variables Results – The results of the study showed that teachers’ fear of COVID-19 significantly affected their happiness level. However, it was found that fear related to COVID-19 significantly predicted resilience and teachers’ resilience level had a significant effect on their happiness. Conclusion – Fear and resilience associated with COVID-19 have a significant impact on happiness. In addition, psychological resilience was found to have a mediating effect on the relationship between fear and happiness associated with COVID-19. The findings of this study will lead the other researchers to expand their studies to assess other behavioral variables, such as apathy and depression that might influence the relationship between fear of covid, resilience and happiness.
First-Principles Study on the Adsorption Characteristics of Corrosive Species on Passive Film TiO2 in a NaCl Solution Containing H2S and CO2

The adsorption characteristics of corrosive anions (Cl−, HS−, S2−, HCO3− and CO32−) on TiO2 of TC4 titanium alloy in a NaCl solution containing H2S and CO2 were studied by density functional theory (DFT). The stable adsorption configuration of each corrosive species on the TiO2 (110) surface was obtained by geometric optimization, and the electronic structure and interface binding energy were calculated and analyzed. The results showed that the optimal adsorption positions of Cl−, HS−, S2−, HCO3−and CO32− on TiO2 (110) were all bridge positions. There was a strong charge interaction between the negatively charged Cl, S and O atoms in Cl−, HS−, S2−, HCO3− and CO32− and the positively charged Ti atoms of TiO2. The interface bonding was mainly caused by charge movement from around Ti atoms to around Cl, O, S atoms. The energy levels were mainly caused by the electron orbital hybridization of Cl-3p5, S-3p4, O-2p4 and Ti-3d2. All adsorption configurations were chemical adsorption. The order of influence of the five ions on the stability of TiO2 was S2− > CO32− > Cl− > HS− > HCO3−. Finally, a novel corrosion mechanism was proposed to illustrate the dynamic evolution processes of pits.
Protective effect of probiotics and ascorbic acid on bile duct ligation-induced chronic hepatic encephalopathy in rats

Background and purpose: Hepatic encephalopathy (HE) is a brain dysfunction caused by acute and chronic hepatic failure. The pathogenesis of HE is unknown, although small intestinal bacterial overgrowth associated with chronic liver damage, hyperammonemia, and oxidative stress are considered major factors for HE. Effective lowering of circulating ammonia and neuroinflammation is the main strategy for preventing and treating HE in cirrhosis. In the present study, the protective effect of probiotics (Lactobacillus plantarum and Bacillus clausii) and ascorbic acid in combination was assessed in bile duct ligation (BDL)-induced chronic HE in rats. Experimental approach: Sprague Dawley rats were divided into five groups (n = 6). All groups were subjected to double ligation of the bile duct and fed a hyperammonemia diet, except group I (normal control). Groups III and IV were treated with a low and high dose of combination therapy, respectively, while group V was given lactulose. Four weeks post ligation, behavioral, biochemical, and neurochemical parameters were measured. The liver and brain were dissected for histopathology and protein analyses. Findings / Results: Combination therapy reduced plasma AST, ALT, ALP, and ammonia levels and attenuated hepatic inflammation/fibrosis in cirrhotic rats. Furthermore, combination therapy significantly improved behavioral parameters and restored the antioxidant enzyme activity. Histological changes were observed in the brain and liver of BDL animals. Conclusion and implications: The additive impact of probiotics and ascorbic acid on BDL-induced chronic HE in rats was mediated by a reduction in ammonia and oxidative stress, implying the therapeutic potential of combination therapy in HE.

Machining feasibility and Sustainability study associated with air pressure, air flow rate, and nanoparticle concentration in Nanofluid minimum quantity lubrication-assisted hard milling process of 60Si2Mn steel

In recent years, more efficient hard machining processes have notably increased in demand for higher productivity but environmental friendliness. High hardness and strength as well as the enormous amount of cutting temperature are still the biggest obstacles. Nanofluid minimum quantity lubrication (NFMQL)–assisted hard machining has become a feasible and promising solution to overcome these problems. The work presents the experimental study on the effects of air pressure (5, 6, and 7 bar), air flow rate (150, 200, and 250 L/min), and Al2O3 nanoparticle concentration (0.5, 1.0, and 1.5%) on minimum quantity lubrication (MQL) hard milling process of 60Si2Mn (50÷52HRC) using vegetable oil as the based fluid. Box–Behnken experimental design and ANOVA analysis were employed to investigate the influences and interaction effects of input parameters on cutting forces, surface roughness, and surface microstructure. This study will be used for selecting the optimum air pressure, air flow rate, and Al2O3 nanoparticle concentration for efficient cooling lubrication performance of MQL in sustainable hard machining. The obtained results show that the optimal values for air pressure and nanoparticle concentration. For Q = 200 L/min, the optimal p is 6.0 bar and the optimal nanoparticle concentration (NC) is 0.9%. For Q = 250 L/min, the optimal p is 5.2 bar, and the optimal NC is 1.2%. Furthermore, using air flow rate Q = 250 L/min gives better results than Q = 200 L/min, but the selection will be depended on the specific equipment conditions.
First report of three novel Bartonella species isolated in rodents and shrews from nine provinces of Thailand

Background and Aim: Bartonella spp. are Gram-negative zoonotic bacteria that are transmitted to humans by several types of animal hosts, including rodents. Several studies have been conducted on the prevalence of Bartonella infections in rodents. However, the risk of rodent-associated Bartonella spp. infection in humans remains unclear. This study aimed to estimate the prevalence and genetic heterogeneity of Bartonella spp. in rodents and shrews from nine provinces of Thailand using culture and molecular techniques. Materials and Methods: A total of 860 blood samples from rodents and shrews across nine provinces of Thailand were collected from January 2013 to June 2016. Bartonella spp. were isolated from all samples using conventional culture techniques and polymerase chain reaction. Phylogenetic tree analysis was used to align the Bartonella sequences obtained from this study. Results: The prevalence of Bartonella spp. in rodents and shrews was 11.5% (99/860, 95% confidence interval: 9.38–13.64%). The following nine species of Bartonella were detected: Bartonella tribocorum, Bartonella rattimassiliensis, Bartonella queenslandensis, Bartonella elizabethae, Bartonella chanthaburi spp. nov., Bartonella satun spp. nov., Bartonella coopersplainsensis, Bartonella ranong spp. nov., and Bartonella henselae. The prevalence of Bartonella-positive animals differed significantly among provinces. Conclusion: To the best of our knowledge, the three novel Bartonella spp. isolated from rodents and shrews across Thailand were detected for the first time in this study. Further studies on the epidemiology of Bartonella infection in rodents and its interaction with human health should be conducted in accordance with the Thai government’s “One Health” approach to humans, animals, and the environment.
The Impact of Information and Communication Technology Capability on the Competitive Advantage of Small Businesses

The aim of this paper is to establish how Information and Communication Technology (ICT) capability has no effect on competitive advantage through the entrepreneurial orientation and organizational agility of Indonesian SMEs in the apparel retail sector. The study is based on resources that cannot be directly converted into the competitive advantage of companies but must instead be subjected to an entrepreneurial process and offer new insights into the use of ICT as a valuable corporate resource. The paper is based on a quantitative approach using a population comprising apparel retailers from traditional markets in Jakarta, Indonesia. The sample was obtained using random sampling. The survey was conducted among 462 small businesses across five traditional apparel markets managed by PD. Pasar Jaya. The data were processed using Structural Equation ModelingPartial Least Squares. The results show that ICT capability has no significant effect on competitive advantage, although it does have a significant effect on entrepreneurial orientation and organizational agility. Organizational agility and entrepreneurial orientation have a significant effect on competitive advantage, thus indicating that ICT capability in small businesses cannot be directly converted into a competitive advantage. The finding of the research is that ICT capability is able to create competitive advantage in small businesses but only when present in conjunction with entrepreneurial orientation and organizational agility.
Cryptocurrencies Intraday High-Frequency Volatility Spillover Effects Using Univariate and Multivariate GARCH Models

Over the past years, cryptocurrencies have drawn substantial attention from the media while attracting many investors. Since then, cryptocurrency prices have experienced high fluctuations. In this paper, we forecast the high-frequency 1 min volatility of four widely traded cryptocurrencies, i.e., Bitcoin, Ethereum, Litecoin, and Ripple, by modeling volatility to select the best model. We propose various generalized autoregressive conditional heteroscedasticity (GARCH) family models, including an sGARCH(1,1), GJR-GARCH(1,1), TGARCH(1,1), EGARCH(1,1), which we compare to a multivariate DCC-GARCH(1,1) model to forecast the intraday price volatility. We evaluate the results under the MSE and MAE loss functions. Statistical analyses demonstrate that the univariate GJR-GARCH model (1,1) shows a superior predictive accuracy at all horizons, followed closely by the TGARCH(1,1), which are the best models for modeling the volatility process on out-of-sample data and have more accurately indicated the asymmetric incidence of shocks in the cryptocurrency market. The study determines evidence of bidirectional shock transmission effects between the cryptocurrency pairs. Hence, the multivariate DCC-GARCH model can identify the cryptocurrency market’s cross-market volatility shocks and volatility transmissions. In addition, we introduce a comparison of the models using the improvement rate (IR) metric for comparing models. As a result, we compare the different forecasting models to the chosen benchmarking model to confirm the improvement trends for the model’s predictions.
Dynamic Optical Power Measurements and Modeling of Light-Emitting Diodes Based on a Photodetector System and Photo-Electro-Thermal Theory

Optical measurements based on integrating sphere are primary suitable for steady-state measurements and unsuitable for dynamic real-time measurements. This paper presents an alternative method using the combination of a photodetector system and the dynamic photo-electro-thermal theory for real-time optical measurements. It is demonstrated that the voltage output of a photodetector can be correlated to the optical power in real time. Such method has been successfully applied to analyze a phosphor-converted white light-emitting diode (PC white LED) using an extended dynamic model with separate calculations of optical power from the blue LED chips and phosphor layer. Both calculated and practical results are included to confirm the validity of the new method.
Radiosurgery for multiple brain metastases using volumetric modulated arc therapy: a single institutional series

Background Patients with brain metastases (BM) live longer due to improved diagnosis and oncologic treatments. The association of volumetric modulated arc therapy (VMAT) and image-guided radiation therapy (IGRT) with brain radiosurgery (SRS) allows complex dose distributions and faster treatment delivery to multiple lesions. Materials and methods This study is a retrospective analysis of SRS for brain metastasis using VMAT. The primary endpoints were local disease-free survival (LDFS) and overall survival (OS). The secondary outcomes were intracranial disease-free survival (IDFS) and meningeal disease-free survival (MDFS). Results The average number of treated lesions was 5.79 (range: 2–20) per treatment in a total of 113 patients. The mean prescribed dose was 18 Gy (range: 12–24 Gy). The median LDFS was 46 months. The LDFS in 6, 12, and 24 months was for 86%, 79%, and 63%, respectively. Moreover, brain progression occurred in 50 patients. The median overall survival was 47 months. The OS in 75%, 69%, and 61% patients was 6, 12, and 24 months, respectively. IDFS was 6 and 24 months in 35% and 14% patients, respectively. The mean MDFS was 62 months; it was 6 and 24 months for 87% and 83% of patients. Acute severe toxicity was relatively rare. During follow-up, the rates of radionecrosis and neurocognitive impairment were low (10%). Conclusion The use of VMAT–SRS for multiple BM was feasible, effective, and associated with low treatment-related toxicity rates. Thus, treatment with VMAT is a safe technique to plan to achieve local control without toxicity.

Investigating the Impact of Dragon Fruit Peel Waste on Starch Digestibility, Pasting, and Thermal Properties of Flours Used in Asia

As a by-product of dragon fruit consumption, dragon fruit peel (DFP) was developed into powder as a natural ingredient. Nevertheless, the effect of DFP on the physicochemical properties of flours used in Asian food processing and cooking remains unknown. In this study, starch digestibility, thermal, pasting, and physicochemical properties of DFP and flours (potato, rice, glutinous rice, and wheat) were characterized. It was found that DFP contained 65.2% dietary fiber together with phenolic compounds, betacyanins, and antioxidant activity. The results demonstrated that DFP (from 125 to 500 mg) reduced starch digestibility of flours, rapidly digestible starch, and slowly digestible starch, along with an increased proportion of undigested starch. A marked increase in phenolic compounds, betacyanins, and antioxidant activity occurred when DFP and flour were incubated for 180 min under simulated gastrointestinal digestion. The results indicate that bioactive compounds in DFP were highly bioaccessible and remained intact after digestion. Moreover, DFP exerted a significantly lower gelatinization enthalpy of flours with increasing peak viscosity and setback with decreasing pasting temperature. FTIR confirmed the decreased ratio at 1047/1022 cm−1, indicating the disruption of short-range orders of starch and DFP. These findings would expand the scope of DFP food applications and provide a knowledge basis for developing DFP flour-based products.
Comparison of Musical Expression of Distinguished and Unnamed Pianists in Tonal Tension and Attraction Models

Musical expression of piano performances by some distinguished pianists has been analyzed by the authors. In the analysis, the tonal tension and attraction models have been used, those are introduced in the literature of the generative theory of tonal music named “Tonal Pitch Spaces” by F. Lerdal. From the analysis, some specific features of their musical expression have been obtained. In this article, performances by “unnamed” pianists are analyzed in the same models and compared them to those by the distinguished pianists. By the analyses, the results are obtained, e.g. the difference between the musical expression by the distinguished pianists and that by unnamed pianists is very definite. Keywords—musical expression; tonal music theory; tonal tension; tonal attraction; multiple regression analysis

BBC and New York Times’ Coverage of the May 2021 Israeli Onslaught on Gaza: A Critical Discourse Analysis

The latest Israeli onslaught on Gaza in May 2021 demonstrated the pivotal role of the international media as an influential source of knowledge-gaining, agenda setting, and opinion shaping for various social groups and audiences. Based on theoretical constructs and analytical tools drawn from Critical Discourse Analysis (Fairclough, 1992, 1995), this study aims to analyze how the New York Times and the BBC covered the Israeli onslaught on Gaza during May 2021. I examine the main topics and key linguistic structures the two influential media outlets use in constructing Palestinian and Israeli actors and their violent actions and how such coverage contributes to the construction of a particular ideological representation of the events. The results show that the two media outlets mainly served Israel’s justifications and interests at the expense of Palestinian narrative and rights through the conflation of two main topics in their representation of the Israeli onslaught on Gaza. The Israeli war was constructed as a war against Hamas, and not against the Palestinian people. They depict the onslaught as a retaliation to Hamas’s rockets. Furthermore, the human and material losses inflicted by Israel on Gaza were framed along the lines of “there are victims on both sides”. The two topics reduce Israel’s moral and political responsibility for the massive losses in human life and destruction inflicted upon the Palestinians in Gaza. This study shows the potent role of news media in framing, legitimizing, or delegitimizing political actors and their actions and maintaining power asymmetries between different political groups.
