Participation of members in the majlis taklim is very much needed to make a program successful and run according to the goals that have been set, both the participation of members in planning, implementing, and evaluating. However, during this new normal period, some members did notparticipate much in the majlis taklim that had been held, unlike the case before the new normal. In writing this thesis the type of research used is field research. The method of data collection is observation, interviews, and documentation. There are two types of information in this research, namely key informants and supportinginformants. , and the supporting informants are the majlis taklim officials. Based on the results of the research conducted, it is known that the participation of members in the majlis taklim during the new normal period is still relatively low, in contrast to the period before the New Normal. This can be seen from the forms of member participation, be it from planning, implementing, evaluating, monitoring, and supervising the Taklim Majlis, such as attendance or involvement participation, funding participation, staff participation, opinion sharing participation, monitoring participation, motivational participation is still low, not all members activelyparticipate in the activities of the taklim assembly. And the inhibiting factors for member participation in this taklim assembly are economic factors, and work factors, economic factors, educational factors, age factors, length of stay factors. This is seen from the results of observations and interviews that the author did.

Authors: Sulastri Endang , Andriyani Lusi , Zein Achmad Mudjahid
Published: May 2023

Voter participation in an election is often a measure of election success. The higher the level of participation, the higher the public's trust in the election process and the stronger the legitimacy of the elected leader. The City of South Tangerang, which has participated in the regional elections three times until the last election in 2020, has had an interesting experience regarding voter participation. In the previous regional elections, namely in 2010 and 2015, voter participation was never more than 60%. In the 2010 elections, voter participation only reached 56.9%, and in the 2015 elections even decreased to only 56.8%. This number is very far from the average target for regional election participation. In 2020 elections were held during a pandemic, and there was concern that voter participation would decline further. In fact, voter participation rose to 60.48%. From the initial survey, it was found that the KPU of South Tangerang City before the election was worried that participation would decline, so they developed a strategy to increase voter participation. This study aims to determine the strategy for increasing voter participation carried out by the KPU of South Tangerang City in the 2020 elections and to find out the challenges, obstacles, and supporting strengths. The theory used in this study is the theory of voter participation from Hungtinfton, Verba, and Kaats, as well as findings in journals related to strategies for increasing participation. The research method uses a qualitative approach with a descriptive method. Data collection techniques through interviews and documentation. Data analysis: qualitative based on Miles and Huberman. Test the Validity of the Data using Triangulation. The result research showed that the KPU of South Tangerang City, in an effort to increase the level of political participation, used a strategy with the P Process model by starting to use vision and mission analysis, identifying problems, formulating strategies by making activities plans, implementing strategies through socialization with five types of activities: competitions, virtual meetings, print journalism, social media and distribution of visual aids for socialization purposes. All implementations are monitored and evaluated both in the middle and at the end of the activities.

Differential expression of CDKN2A in cancer of the cervix.
Authors: Mamoor Shahan
Published: May 2023

Almost all cervical cancers are caused by infection with high-risk human papillomaviruses (HPVs) (1-3); the transcriptional features that distinguish the gene expression programs of HPV-induced cancers from that of other solid tumors resulting from non-viral abrogation of tumor suppression remain incompletely defined. We mined published microarray datasets (4, 5) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the most common type of cervical cancer, cervical squamous cell carcinoma. We found significant differential expression of the gene encoding cyclin dependent kinase inhibitor 2A, CDKN2A, when comparing tumor tissue from the human cervix to the tissue of origin. CDKN2A mRNA was present at significantly higher quantities in tumors of the cervix as compared to normal tissues from the cervix. Analysis of human survival data revealed that expression of CDKN2A in tumors of the cervix was correlated with overall survival in patients with cervical cancer. CDKN2A expression changes may be important for the initiation or progression of cancer of the cervix in humans.
The Political Economy of Foreign Aid in African States
Authors: Opalo Ken Ochieng'
Published: May 2023

This chapter describes the political economy of foreign aid in African states using the specific example of Uganda. The chapter presents two core arguments. First, that African states have been able to retain their agency and relative policy autonomy despite high levels of aid dependence. This can be explained by donors’ motivations for giving aid (e.g., foreign policy, ideational commitment to fighting poverty, self-interested tied aid, etc.) and African states’ ability to position themselves as important trusted allies to donors. Second, that unpacking donors’ domestic institutional and political motivations for giving aid increases understanding of why donors and multilateral organizations often fail in their efforts to leverage foreign aid for specific ends.

Older Adults Catch Up to Younger Adults on Cognitive Tasks After Extended Training
Authors: Das Priyam , Steyvers Mark
Published: May 2023

Cognitive decline often accompanies natural aging, which results in younger adults outperforming older adults, on average, on tasks requiring attention, memory, or mental flexibility skills. This performance gap between age groups persists even after people train on these tasks, but it remains unclear whether the gap persists when individuals, rather than groups, are compared at different training levels. In this paper, we analyzed 9,923 users between 18-90 years old (63\% over 60) who performed a variety of cognitive tasks on an online cognitive training platform. We quantified an older adult’s potential to catch up to, or perform as well as, a younger adult. We found that the probability of catching up to someone decades younger increases with differential amounts of training on a variety of cognitive tasks. These findings suggest that age-related performance deficits can be overcome with additional training.
Goal-dependent use of temporal regularities to orient attention under spatial and action uncertainty
Authors: Echeverria-Altuna Irene , Nobre Anna C. , Boettcher Sage
Published: May 2023

The temporal regularities in our environments support the proactive anticipation of relevant events. In visual attention, one outstanding question is whether temporal expectations must be linked to locations or motor plans to facilitate behaviour. To test this, we developed a task for manipulating temporal expectations and task relevance of stimuli, while stimulus location and responding hand remained uncertain. Targets were defined by colour on a trial-by-trial basis and had distinct temporal probability structures. They appeared equiprobably in one of two concurrent streams (on the left and right) and required a localisation response. Across two experiments, participants were faster and more accurate at detecting temporally expected targets than unexpected targets. We conclude that temporal expectations learned incidentally from temporal regularities can be called upon in a goal-driven manner to guide behaviour. Moreover, visual temporal attention can facilitate performance in the absence of concomitant spatial or motor expectations in dynamic contexts.
Spurious prospective effects of mindfulness on anxiety and depressive symptoms: Reanalysis of a meta-analytic cross-lagged panel analysis
Authors: Sorjonen Kimmo , Melin Bo
Published: May 2023

A recent meta-analysis claimed decreasing prospective effects of acting with awareness and non-reacting, two facets of dispositional mindfulness, on subsequent anxiety and depressive symptoms. However, the meta-analytic cross-lagged effects were estimated while adjusting for a prior measurement of the outcome variable and it is known that such adjusted cross-lagged effects may be spurious due to correlations with residuals and regression to the mean. We fitted competing models on the same meta-analytic data and found prospective effects of the mindfulness facets on anxiety and depressive symptoms to be spurious. It is important for researchers to be aware of limitations of adjusted cross-lagged effects, meta-analytically estimated or not, in order not to overinterpret findings.
Diverse Adolescents’ Transcendent Thinking Predicts Young Adult Psychosocial Outcomes via Brain Network Development
Authors: Gotlieb Rebecca , Yang Xiao-Fei , Immordino-Yang Mary Helen
Published: May 2023

Developmental scientists have long described mid-adolescents’ emerging capacities to make deep meaning about the social world and self, here called transcendent thinking, as a hallmark developmental stage. In this 5-year longitudinal study, sixty-five 14-18yr-old youths’ proclivities to grapple psychologically with the ethical, systems-level and personal implications of social stories, predicted future increases in the coordination of two key brain networks: the default-mode network, involved in reflective, autobiographical and free-form thinking, and the executive control network, involved in effortful, focused thinking; findings were independent of IQ, ethnicity, and socioeconomic background. This neural development predicted late-adolescent identity development, which predicted young-adult self-liking and relationship satisfaction, in a developmental cascade. The findings reveal a novel predictor of mid-adolescents’ neural development, and suggest the importance of attending to adolescents’ proclivities to engage agentically with complex perspectives and emotions on the social and personal relevance of issues, such as through civically minded educational approaches.
Puzzling out graphic codes
Authors: Morin Olivier
Published: May 2023

This response takes advantage of the diverse and wide-ranging series of comments to clarify some aspects of the target paper, and flesh out other aspects. My central point is a plea to take graphic codes seriously as codes, rather than as a kind of visual art or as a by-product of spoken language; only in this way can the puzzle of ideography be identified and solved. In this perspective, I argue that graphic codes do not derive their expressive power from iconicity alone (unlike visual arts), and I clarify the peculiar relationship that ties writing to spoken language. I then discuss three possible solutions solutions to the puzzle of ideography. I argue that a learning account still cannot explain why ideographies fail to evolve, even if we emancipate the learning account from the version that Liberman put forward; I develop my preferred solution, the “standardization account”, and contrast it with a third solution suggested by some comments, which says that ideographies do not evolve because they would make communication too costly. I consider, by way of conclusion, the consequences of these views for the future evolution of ideography.

Multi-cell probiotic containing bacteria Nitrosomonas sp., Nitrobacter sp., and Bacillus sp. This research was conducted from March to May 2021 at the Fish Disease and Parasite Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine, Riau University. This study aimed to analyze the hematology of Asian redtail catfish reared in media that was added with probiotics periodically and to obtain the best time interval for giving probiotics to the rearing medium. The method used in this study is an experimental method by applying a Completely Randomized Design (CRD) with five treatment levels and three replications. The treatments used were the administration of probiotics at a dose of 0,01 mL/L of water with different time intervals, P0 (without treatment), P1 (5 days once), P2 (10 days once), P3: (15 days once), and P4 (20 days once). Fish were reared for 50 days. The results show that the Asian redtail catfish reared with the addition of probiotics in the rearing medium had a significant effect (P<0.05) with the best time interval being once every 5 days in the P1 treatment, seen from the total erythrocytes 2.43 x 106 cells/mm3, hematocrit level 28.67%, hemoglobin level 7.40 g/dL, total leukocytes 9.92 x 104 cells/mm3, leukocrit level 1.83%, and glucose 49.67 g /dL. Water quality during the study was still in the normal range that could support the growth of Asian redtail Catfish, namely temperature 26-27.1 C, pH 5.8-6.5, DO 6.0-7.4 mg/L, and ammonia 0.0011-6.5 0.0047 mg/L

This research was conducted in May - June 2018 by surveying and taking a sample from Malang Rapat water on the East Coast of Bintan Island, Kepulauan Riau to determine the abundance and distribution of toxic benthic dinoflagellates associated with seaweed (Sargassum sp) and seagrass (Enhalus accoroides). Samples were taken from four sampling locations which were carried out purposively by taking into account the different anthropogenic activities that occurred in each region. The results of the study found 3 genera of toxic benthic dinoflagellates, namely Gambierdiscus sp, Ostreopsis sp, and Prorocentrum sp. The highest abundance of toxic benthic dinoflagellates associated with Sargassum sp was found in station 3, which was 302.279 cells/g, and the lowest at station 4 with (133.529 cells/g), while E. accoroides has the highest abundance at station 1 which was 620.65 cells/g). The abundance of toxic dinoflagellates in Sargassum sp has a positive correlation with nitrate concentration, but on the contrary, it was negatively correlated with the concentration of nitrate and phosphate in these waters to E. accoroides. The measured water quality parameters were still within the tolerance range for the marine organism. Further research is still needed to answer the cause of these differences and whether there are any fluctuations of abundance and the specific appearance of the toxic dinoflagellate.

Indian Scad Fish (Decapterus russeli) are the most dominant small pelagic fish resources landed in the Sibolga Archipelago Fisheries Port. The production of Indian Scad Fish catches that are landed in PPN Sibolga on average fluctuates every year. Therefore, it is necessary to analyze the catch of Indian Scad Fish to control the level of exploitation and create effective fishing operations so that the utilization of Indian scad fish resources can run optimally and sustainably. This study aims to determine the percentage level of utilization of Indian scad fish (Depterrus russeli) that landed at the Sibolga Nusantara Fisheries Port, North Sumatra. This research was conducted in March – April 2022. The method used in this research is the survey method. The type of data collected is secondary data. The data analysis used includes standardization of Indian scad fish fishing gear, sustainable potential and optimum effort, total allowable catch (TAC), utilization rate, and effort. From the research results, it was found that the highest production of Indian scad fish catches in 2019 was 6,392 tons. Based on the calculation of MSY and the optimum effort in 2017-2021 of 5,934.97 tons/year, meaning that the maximum catch of Indian scad fish that can be caught is 5,934.97 tons/year and the number of allowable catches is 4,747.98 tons/year or 80% of the maximum catch and utilization rate of Indian scad fish for 5 years is 81.41%.

Red ginger contain antioxidant that can be used to enhance the immune system of fish. A study was conducted from September to December 2021 to understand the kidney structure of Pangasianodon hypophthalmus that fed with red ginger fermented pellets. The fermented red ginger juice was obtained by juicing 500 g of red ginger in 3L water, boiled and mixed with 175 ml molasses, 65 ml yogurt and 50 mg yeast and then was fermented for seven days. The fermented red ginger juice was obtained by juicing 500 g of red ginger in days. The fermented red ginger juice was mixed with fish feed pellets, namely T1 (150 mL/Kg), T2 (175 mL/Kg), T3 (200 mL/Kg), Cn (no red ginger juice and no infection), Cp (no red ginger juice and infection by A. hydrophila). The fish were reared in 30L aquaria. Fish sample was P. hypophthalmus fingerling (10-12 cm and 5-7 g), 10 fishes/aquarium. The fish were fed 3 time a day, adlibitum. In the 30th day, A. hydrophila was injected to the treated fish   (0.1.ml of 108 cells/ml, subcutan injection). In the 14th after the infection kidney sample was collected and processed for histological study. Result shown that there were differences in kidney tissue of fish in each treatment. The worst condition was obtain in Cp, while the best was in T2. The renal structure of Cp showed abnormalities such as hemorrhage, cell necrosis, enlarged Bowman's cyst, and tubular degeneration, while the T2 kidney showed mild lesions specifically haemorrhagic. This fact indicates that fermented red ginger can improve fish immunity against A. hydrophila infection
