Contributions of representational distinctiveness and stability to memory performance and age differences

ABSTRACT Long-standing theories of cognitive aging suggest that memory decline is associated with age-related differences in the way information is neurally represented. Multivariate pattern similarity analyses enabled researchers to take a representational perspective on brain and cognition, and allowed them to study the properties of neural representations that support successful episodic memory. Two representational properties have been identified as crucial for memory performance, namely the distinctiveness and the stability of neural representations. Here, we review studies that used multivariate analysis tools for different neuroimaging techniques to clarify how these representational properties relate to memory performance across adulthood. While most evidence on age differences in neural representations involved stimulus category information , recent studies demonstrated that particularly item-level stability and specificity of activity patterns are linked to memory success and decline during aging. Overall, multivariate methods offer a versatile tool for our understanding of age differences in the neural representations underlying memory.
Effects of bulb types and plant growth regulators on the growth and flowering of tuberose (Polianthes tuberosa L.)

Plant growth regulators have significant role in modifying the growth and flowering of plants. An experiment was conducted at the Landscaping Section of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from March to October, 2018 to investigate the effects of bulb types and plant growth regulators on growth and flowering of tuberose. The two-factor experiment consisted of two bulb types viz., single (S1) and double (S2), and different levels of plant growth regulators viz., = control (T0), GA3 @ 200 ppm (T1), GA3 @ 400 ppm (T2), NAA @ 100 ppm (T3) and NAA @ 300 ppm (T4). The experiment was laid out in Randomized Complete Block Design with three replications. Bulb types and plant growth regulators had significant effects on almost all the parameters under study. The highest flower yield (25.35 t/ha) of tuberose was recorded from the double bulb while the lowest flower yield (22.53 t/ha) of tuberose was obtained from single bulb. The highest flower yield (26.10 t/ha) of tuberose was obtained from GA3 @ 400 ppm, whereas, the lowest flower yield (12.20 t/ha) was recorded from control treatment. Combined treatment of double bulb with GA3 @ 400 ppm gave the highest flower yield (28.91 t/ha) of tuberose while combined treatment of single bulb with control treatment provided the lowest flower yield (14.63 t/ha). Therefore, double bulb along with the application of GA3 @ 400 ppm was found to be better in respect of growth and flowering of tuberose.
IMPACT OF SOCIAL MEDIA USE ON COMMUNITY PSYCHOLOGY AND ITS IMPLICATIONS IN COUNSELING

Social media is a communication tool that is commonly used by everyone in today's technological era. Excessive use of social media will cause addiction, and have an impact on people's psychology. This article aims to reveal data on the impact of social media addiction on the psychology of society and its implications for counseling. The research uses qualitative research methods, especially phenomenology. The research instrument is the researcher himself, and for data collection using in-depth interviews and observation. The research respondents are the people of West Sumatra with male and female sexes aged 15 to 50 years. The data analysis technique is using Miles and Huberman data analysis with the following steps; data reduction, data display, and conclusion drawing/verification. The results of the study found that the psychological impact of social media addiction generally affects people's cognitive and emotions. The positive impact is cognitive, namely increasing insight and thinking skills, as well as giving birth to various creative ideas. The negative impact is causing forgetfulness, panic, dead-end thoughts, lack of logical thinking. Emotionally the positive impact of using social media by the community is to create happiness, optimism, motivation, enthusiasm, enthusiasm. The negative impact is causing anxiety, despair, sadness, resentment, anger and frustration. The results of this study have implications for counseling, namely preventively developing counseling techniques that aim to reduce social media addiction. Curatively, it can develop counseling techniques that can improve brain function and reduce anxiety levels.
Association between Perceived Organizational Politics and Intentions to Quit: Mediating Role of Emotional Exhaustion

1. Ph. D Scholar, Department of Management Sciences, COMSATS University, Islamabad, Pakistan 2. Assistant Professor, Department of Applied Psychology, NUML, Islamabad, Pakistan 3. Postdoctoral Research Fellow, School of Management, Jiangsu University, Zhenjiang, Jiangsu, China PAPER INFO ABSTRACT Received: March 14, 2021 Accepted: June 05, 2021 Online: June 10, 2021 This research investigates proposed associations between the perceived organizational politics on intentions to quit and emotional exhaustion. A sample of faculty members (N=220) from five higher education commission approved public sector universities of Islamabad participated. Data were collected by using non-probability sampling technique i.e. convenient. Participants provided information on socio-demographic variables and self-reported questionnaires on study variables. Psychometric properties of the study variables were found satisfactory. Regression analysis through statistical package for social sciences was carried out to test the hypotheses. Results indicated perceived organizational politics significantly related to intentions to quit, as well as to emotional exhaustion. Emotional exhaustion was also found to be positively related to intentions to quit. Further, emotional exhaustion partially mediated the relationship between perceived organizational politics and intentions to quit. Findings suggested that perceived organizational politics emotionally exhausts faculty members of the universities, leading them to have intentions to quit their jobs. Universities need to identify perceived organizational politics in the work environment and efforts need to be focused on addressing this phenomenon.

Exploring the Stability of Fe–Ni Alloy Nanoparticles Exsolved from Double-Layered Perovskites for Dry Reforming of Methane

Exsolution is emerging as a promising route for the creation of nanoparticles that remain anchored to the oxide support, imparting remarkable stability in high temperature chemical processes such as dry reforming of methane. This process takes place at temperatures around 850 °C, which causes sintering-related issues in catalysts prepared using conventional impregnation methods, which could be overcome by using exsolution functionalized oxides. In this work, FeNi3 alloy nanoparticles exsolved from Sr2FexNi1-xMoO6-δ double-layered perovskites were evaluated as a dry reforming catalyst, paying special attention to structure–activity relationships. Our results indicate that increasing the Ni content favors the nanoparticle dispersion, eventually leading to increased CO2 and CH4 conversions. The exsolved nanoparticles presented remarkable nanoparticle size (ca. 30 nm) stability after the 10 h treatment, although the formation of some phase segregations over the course of the reaction caused a minor decrease in the nanoparticle population. Overall, the results presented here serve as materials processing guidelines that could find further potential use in the design of more efficient (electro)catalysts in other fuel production or energy conversion technologies.
Antimicrobial Properties of Strontium Functionalized Titanium Surfaces for Oral Applications, A Systematic Review

The aim of this systematic review was to assess the current scientific evidence of the antimicrobial potential of strontium (Sr) when used to functionalize titanium (Ti) for oral applications. Out of an initial list of 1081 potentially relevant publications identified in three electronic databases (MEDLINE via PubMed, Scopus, and Cochrane) up to 1 February 2021, nine publications based on in vitro studies met the inclusion criteria. The antimicrobial potential of Sr was investigated on different types of functionalized Ti substrates, employing different application methods. Nine studies reported on the early, i.e., 6–24 h, and two studies on the late, i.e., 7–28 days, antimicrobial effect of Sr, primarily against Staphylococcus aureus (S. aureus) and/or Escherichia coli (E. coli). Sr-modified samples demonstrated relevant early antimicrobial potential against S. aureus in three studies; only one of which presented statistical significance values, while the other two presented only the percentage of antimicrobial rate and biofilm inhibition. A relevant late biofilm inhibition potential against S. aureus of 40% and 10%—after 7 and 14 days, respectively—was reported in one study. Combining Sr with other metal ions, i.e., silver (Ag), zinc (Zn), and fluorine (F), demonstrated a significant antimicrobial effect and biofilm inhibition against both S. aureus and E. coli. Sr ion release within the first 24 h was generally low, i.e., below 50 µg/L and 0.6 ppm; however, sustained Sr ion release for up to 30 days, while maintaining up to 90% of its original content, was also demonstrated. Thus, in most studies included herein, Sr-functionalized Ti showed a limited immediate (i.e., 24 h) antimicrobial effect, likely due to a low Sr ion release; however, with an adequate Sr ion release, a relevant antimicrobial effect, as well as a biofilm inhibition potential against S. aureus—but not E. coli—was observed at both early and late timepoints. Future studies should assess the antimicrobial potential of Ti functionalized with Sr against multispecies biofilms associated with peri-implantitis.
Lender Monitoring and the Efficacy of Managerial Risk-Taking Incentives

Firms provide convexity in managers' compensation plans (vega) to induce risk-averse managers to pursue risky, positive net present value projects. The resulting alignment of managers' and shareholders' incentives creates conflicts with lenders, who face an increased risk of default when managers pursue risky investments. We hypothesize that lenders would respond by stepping up their monitoring and threatening foreclosure to inhibit managers from acting on their vega incentives. Strong lender monitoring should, thus, reduce the efficacy of vega incentives. We test this hypothesis in a unique setting, where lenders purchase credit insurance, reduce their exposure to downside risk, and lower their monitoring. Afterward, we find a stronger association between vega incentives and the firms' risky investments. We contribute to the literature by showing that strong lender monitoring reduces the effectiveness of vega incentives and, thus, of the compensation mechanisms that boards of directors put in place to resolve manager-shareholder conflicts.

‘None of my other teachers know my face/emotions/thoughts’: digital technology and democratic assessment practices in higher education physical education

ABSTRACT Digital technology and its use within democratic pedagogy has been an under-researched area in physical education (PE) and higher education (HE). Furthermore, we know little about how democratic assessment methods are experienced by students in HE. As such, this article explores student perceptions and experiences of democratic assessment practices through video narratives in HE PE and how these video narratives allowed students to demonstrate their learning. Using student responses from an e-questionnaire, the findings discuss how the video narratives elevate students’ self-awareness, generate emotive and affective responses, elicit performative acts and provide an authentic assessment experience. In particular, the consideration of a student’s environment is presented as a novel finding in comparison to previous literature. The authors discuss these findings in relation to teachers’ democratic practices and video narratives as a vehicle for supporting authentic assessment experiences.
Mesenchymal Stem Cells in Sepsis: From Basic Research to Clinical Application

Sepsis is a life-threatening organ dysfunction caused by a deregulated host response to infection, and is the most common cause of death in the intensive care unit. Although the pathogenesis of sepsis has made substantial progress, the current clinical treatment of sepsis is basically symptomatic treatment, including the infusion of antibiotics and catecholamine, and no effective conventional treatment has been found. The focus of research is Mesenchymal Stem Cells (MSCs). It can be a novel therapeutic tool to treat sepsis. MSCs have the characteristics of anti-inflammatory, antibacterial, anti-apoptosis, regulating immunity, and tissue and organ repair. The pre-clinical research and a few clinical phase I studies are reviewed to review the current
Teacher Trainees Readiness for E-learning in Colleges of Education in Ghana

Using the Unified Theory of Acceptance and Use of Technology, the study investigated college students’ readiness for online learning from seven colleges of education in Ghana’s Volta and Oti Regions (UTAUT). The study focused on college students’ eLearning readiness and their perceptions of eLearning in Ghana. The descriptive phenomenological research design was used in this study. Using the convenience sampling technique, seven colleges were chosen from a pool of forty-six colleges of education. The participants were interviewed through WhatsApp and Telegram chats. For this study, the phenomenological data analysis process developed by Colaizzi was used. The findings were organized into the following themes: Adaptability Struggle, The New Digital Divide, A shift in teacher professional development, A shift in teacher professional development, Interactivity, and Time Management. According to the findings, colleges used Google Classroom, WhatsApp, Edmodo, and Telegram for learning and teaching. It was discovered that students face internet connectivity issues, accessibility issues, poor time management, adaptability challenges, technical support issues, high cost of internet bundle challenges with smart devices, and disruption as a result of the need to assist with other domestic activities. Due to the numerous challenges associated with online learning, college students suggest that the teaching and learning should be done in conjunction with face-to-face learning (blended learning) or suspended entirely.
The Measurement of Service Quality at Linow Lake Tourist Attraction Using Servqual Method

The tourism industry sector in North Sulawesi is currently getting more attention by the government. Linow lake is one of the busiest and visited tourist attraction. The tourism industry must apply the concepts, regulations and guidelines in tourism development in order to be able to maintain and increase the number of tourist visits which will lead to economic benefits for the tourism industry and local communities. In Tomohon city itself, there are so many natural tourist attractions which as beautiful as Linow Lake. In order for tourists to feel satisfied and want to visit the Linow lake on the next day, the quality of service cannot be overlooked. For this reason, measurement of service quality was carried out using five dimensions, Tangible, Reliability, Assurance, Responsiveness, and Empathy. It will be measured to 100 respondents, how the expectations and perceptions of tourists about the service quality at Linow Lake tourist attractions. Measurements were carried out by using servqual method, which calculates the difference between the expectations and perceptions of tourists consisting of 22 questions. The result of the analysis showed a positive value of 0.17, which means that the service quality at Linow Lake tourist attractions has exceeded the expectations of visitors. However, one dimension, responsiveness, gets a negative value, and it is expected that the management can improve the quality of its services in terms of response speed, especially on busy visitor days.
Anticoagulant Activity of Mangrove (Avicennia alba) Leaves Extract in Vitro

Anti-coagulants are substances used to prevent the formation of thromboembolism, one of the causes of cardiovascular disease. Since cardiovascular is a disease as the leading cause of death in the world, exploration of novel and more effective anticoagulant is very needed. Mangroves contain flavonoid and sulphated polysaccharide compounds that potential as anti-coagulants. This study aimed to determine the anti-coagulant activity of ethanol extract and fractions of mangrove leaves (Avicennia alba) in human blood cells in vitro. A. alba leaves were collected at Teluk Ekas, East Lombok, Indonesia. The leaves were macerated with 96% ethanol (3x24h) and then evaporated. The extract was then fractionated to obtain the n-hexane, chloroform, and residual fractions. Anti-coagulant activity of ethanol extract and the three fractions were tested in vitro to five human blood samples by the method of Lee-White and Eustrek, compared to heparin as a positive control. Phytochemical screening of the ethanol extract indicated that A. alba leaves extract contains alkaloids, tannin, saponin, flavonoids, sulphated polysaccharide, and terpenoid. The results of Lee-White method were the ethanol extract (1 mg.mL-1), and three fractions (0.5 mg.mL-1) have anti-coagulant activity. Statistical analysis showed that the anti-coagulant activity of the ethanol extract was significantly different (P<0.05) compared to the normal group and fractions and were not significantly different (P>0.05) compared to heparin. Ethanol extract and the three fractions of A. alba leaves have anti-coagulant activity in vitro. The anti-coagulant activity of ethanol extract (1 mg.mL-1) was comparable to heparin (25 IU) and was better than the three extract fractions (0.5 mg.mL-1). Further research is needed to test the anticoagulant activities of isolated sulphated polysaccharides and flavonoid that can be developed as anticoagulant agents.
Reinforcement Learning Based Truck-and-Drone Coordinated Delivery

Coronavirus disease 2019 has brought a great challenge to the supply of daily necessities and medical items for home-quarantined people. Considering the unmanned operation, agility, and use of clean energy of drones, we propose a novel truck-and-drone coordinated delivery system that does not require direct human contact during the delivery process. All final deliveries are completed by the drone while the truck acts as a movable charging station and a carrier, so that the contagion risks are reduced. Moreover, we spilt the whole delivery problem into the customer-clustering problem and the routing problems of both the truck and the drone. An encoder–decoder framework combined with reinforcement learning is created to solve the routing problems without handcrafted designed heuristics. We design the different problem contexts specific to the truck routing problem and the drone routing problem. The experimental results show that the proposed approach has good generality and can consequently be applied to problems of different scales with high time efficiency.
DOES success entail ability?

Imagine a great wave is rising and I have dashed into the sea with my surfboard. You know nothing about me: perhaps I am one of the world’s great surfers; perhaps I am a fool. What would it tell you about my abilities, if I were ride into the coast on that wave? Would it mean I am able to surf a wave like that? Does success entail ability? Call the principle that it does Success.1 When we focus on successful action, Success is compelling. Austin (1961) said that “it follows merely from the premise that [a golfer sinks a putt], that he has the ability to do it, according to ordinary English”. And indeed when someone succeeds in something, like sinking a putt or surfing a wave, one is forced to concede they were able to do that. This is what Success would lead us to expect. But when success is not yet assured, the lesson seems different. When said before the fact, the claim that I can surf that wave is strong — it says that surfing that wave is within my control. This intuition, call it the control intuition, drives against Success. Just doing something does not demonstrate it is within my control: flukes do happen. So, if the control intuition is right, success should not demonstrate ability. ∗Thanks to the participants of the Rutgers Language Workshop, and Fabrizio Cariani, Justin Khoo, Jeff King, Annina Loets, Matthew Mandelkern, Milo Phillips-Brown, Robert Stalnaker, and Barbara Vetter. Special thanks to Ginger Schultheis for comments on multiple drafts. 1I will focus exclusively on whether Success is valid for specific ability attributions which concern whether an agent is able to perform an action at a particular time (generally in the future), like lifting 200 pounds right now or hitting a bullseye on this throw. These are to be contrasted with general or generic ability ascriptions, which say that an agent has the ability to perform an action, not at a specific time, but rather in general. Mandelkern et al. (2017) argue that the semantics for generic ability ascriptions is derived by simply embedding a specific ability ascription under a generic operator.
Oral Health Status of the Refugee Population in Utah

Objectives: This aimed to identify current gaps in oral health attitudes and treatment among refugees living in Utah. The cross-sectional study was conducted at partner sites identified by the Refugee Education & Training Center, State of Utah. A convenience sample of 103 adults was recruited from the refugee communities settled in Utah. Data collection included the following elements: demographic characteristics, self-reported oral health status, attitudes, and knowledge, DMFT (decayed, missing, filled teeth), and periodontal status. Results: Clinical findings revealed pervasive oral health concerns and treatment needs. Only 14% were evaluated to have healthy periodontal conditions, while 86% of participants had a least one site of untreated decay. All participants were evaluated to be in need of treatment. Approximately 36% required prompt treatment, while 43.7% were evaluated to require urgent treatment due to pain or infection. This study also identified low levels of oral health knowledge, with only 13% answering all knowledge questions correctly. Conclusion: This study provided evidence of the extent of oral disease and decay among refugees resettled in Utah and identified the low levels of oral health knowledge in this population. Educational program, especially those evaluate cultural perception, would be a powerful avenue for improving the oral health status of refugees living in Utah.
