TINGKAH LAKU LOBSTER PASIR (Panulirus homarus) YANG DIPELIHARA PADA SHELTER BERBEDA
Authors: Lesmana Dudi , Sri Mumpuni Fia
Published: November 2022

Efforts are being made to reduce the high rate of cannibalism by using shelters in their maintenance of cages. Shelters are needed as a hiding place for moulting of lobsters, as well as expanding the living area. The aims of this study was to determine the behavior of spiny lobster including the frequency of molting and the level of cannibalism. This research took place in July–October 2021, at the Vocational School, IPB University. The design used in this research was a completely randomized design (CRD) using 4 treatments and 3 replications. The treatments in this study consisted of rearing of lobster with box-hole brick shelter (A), rearing of lobster with round hole brick shelter (B), rearing of lobster with pipe shelter (C) and rearing of lobster without shelter (K). The molting frequency of lobsters reared with box-hole shelters tended to be higher (60.0%) than other treatments but not significantly different (P>0.05). The percentage of cannibalism in lobsters reared without shelters / control (47.67%) tended to be higher than lobsters reared in batako shelters.

Published: November 2022

Background: Currently, there is little evidence to guide clinical management of pregnancies after stillbirth. Our study aims to evaluate the pregnancy outcome in pregnant women with a previous stillbirth, by applying a standardized protocol for etiologic investigations and subsequent treatment of the underlying etiology. Methods: A retrospective cohort study on a group of 100 women with history of stillbirth, occurred in single pregnancy between 2005 and 2021, was performed. All patients were followed up in their subsequent pregnancies (n = 153) in a tertiary university hospital. During the preconception period causes of stillbirth were investigated and a correction of modifiable risk factors was encouraged with a multidisciplinary approach. Data about pregnancy management, obstetric complications, gestational age at delivery, mode of delivery and neonatal outcomes were collected. Results: The analysis of previous stillbirth revealed that, by using the ReCoDe classification, the most common identifiable causes of death were fetal growth restriction (21%), placental abruption (11%) and “other placenta insufficiencies” (26.7%), whereas 15.8% of stillbirth was unexplained. Out of 153 subsequent pregnancies, 131 (85.62%) resulted in live births, 15 (9.8%) in a first trimester miscarriage, and 7 (4.57%) in second trimester miscarriage; no cases of stillbirth recurrence occurred. Obstetric complications in subsequent pregnancies included gestational diabetes (21.4%), gestational hypertensive disorders (6.1%), intrahepatic cholestasis of pregnancy (3.8%), fetal growth restriction (7.6%) and preterm birth (19.8%). The mean gestational age at delivery was 38 weeks with a mean birth weight of 2886.63 g. Conclusions: Our experience is encouraging as reflecting good outcomes in terms of live birth rate in the subsequent pregnancies, with no cases of recurrence. These results are probably due to extensive preconception investigations with a multidisciplinary approach. A preconception evaluation is, thus, essential to improve maternal and fetal outcome in case of history of stillbirth, aiming to minimize the risk of recurrence.

The Gift of a Lifetime: The Hospital, Modern Medicine, and Mortality
Authors: Hollingsworth Alex , Karbownik Chris , Thomasson Melissa , Wray Anthony
Published: November 2022

The past century witnessed a dramatic improvement in public health, the rise of modern medicine, and the transformation of the hospital from a fringe institution to one essential to the practice of medicine. Despite the central role of medicine in contemporary society, little is known about how hospitals and modern medicine contributed to this health transition. In this paper, we explore how access to the hospital and modern medicine affects mortality. We do so by leveraging a combination of novel data and a unique quasi-experiment: a large-scale hospital modernization program introduced by The Duke Endowment in the early twentieth century. The Endowment helped communities build and expand hospitals, obtain state-of-the-art medical technology, attract qualified medical personnel, and refine management practices. We find that access to a Duke-supported hospital reduced infant mortality by 10%, saving one life for every $20,000 (2017 dollars) spent. Effects were larger for Black infants (16%) than for White infants (7%), implying a reduction in the Black-White infant mortality gap by one-third. We show that the effect of Duke support persisted into later life with a 9% reduction in mortality between the ages of 56 and 65. We further provide evidence on the mechanisms that enabled these effects, finding that Endowment-supported hospitals attracted higher-quality physicians and were better able to take advantage of new medical innovations.

Differentiated, rather than shared, strategies for time-coordinated action in social and non-social domains in autistic individuals
Authors: Bloch Carola , Viswanathan Shivakumar , Tepest Ralf , Jording Mathis , Falter-Wagner Christine , Vogeley Kai
Published: November 2022

Autism spectrum disorder (ASD) is a neurodevelopmental condition with a highly heterogeneous adult phenotype that includes social and non-social behavioral characteristics. The link between the characteristics assignable to the different domains remains unresolved. One possibility is that social and non-social behaviors in autism are modulated by a common underlying deficit. However, here we report evidence supporting an alternative concept that is individual-centered rather than deficit-centered. Individuals are assumed to have a distinctive style in the strategies they adopt to perform social and non-social tasks with these styles presumably being structured differently between autistic individuals and typically-developed individuals. We tested this hypothesis for the execution of time-coordinated (synchronized) actions. Participants performed (i) a social task that required synchronized gaze and pointing actions to interact with another person, and (ii) a non-social task that required finger-tapping actions synchronized to periodic stimuli at different time-scales and sensory modalities. In both tasks, synchronization behavior differed between ASD and TD groups. However, a principal component analysis of individual behaviors across tasks revealed associations between social and non-social features for the TD persons but such cross-domain associations were strikingly absent for autistic individuals. The highly differentiated strategies between domains in ASD are inconsistent with a general synchronization deficit and instead highlight the individualized developmental heterogeneity in the acquisition of domain-specific behaviors in ASD. We propose a cognitive model to help disentangle individual-centered from deficit-centered effects in other domains. Our findings reinforce the importance to identify individually differentiated phenotypes to personalize autism therapies.
The coupling between cosmic expansion and gravity causes the accelerated expansion
Authors: lin li xiao
Published: November 2022

There exists a new coupling effect between cosmic expansion and gravity. With this new gravitational coupling, we can simply explain the phenomenon of accelerated expansion of the universe. The calculation results are in full agreement with the cosmological measurements. This proves that the new gravitational coupling is the dark energy. Dark energy does not exist. This theoretical model brings about a new coupling constant for the coupling effect. The value of this coupling constant can be measured by measuring the cosmic redshift at the inflection point of the expansion speed of the universe.

IntroductionPeer review of target volume is recommended as an important step for ensuring high quality radiotherapy. The Royal College of Radiologists considers gynecological cancers as one of the sites where peer review of individual target volumes is required. We report results of an on-demand peer review system for gynecological cancers in our institute. MethodsPeer review was planned for gynecological cancer cases planned for curative intent radiotherapy. On demand peer review was conducted by two senior clinical oncologists specializing in gynecological cancers after segmentation was completed by junior clinical oncologists. Peer review discussions were recorded prospectively in an electronic database. In the present study, data of patients planned from radiotherapy between 15th September 2021 - September 2022 is audited. The compliance to the audit process, proportion of patients requiring major and minor modifications in target volumes, direction of changes noted as well as factors influencing the changes have been reported.ResultsIn the study period, 230 patients underwent planning for curative intent radiotherapy and 204 (88.3%) patients had at least one peer review. Major target volume changes were required in 108 patients, with the majority of changes reported in the nodal CTV. Analysis of P-charts showed a rapid change in proportion of patients requiring major modifications with stabilization at the end of 3 months to 38.2% and 28% for nodal and primary CTV respectively. Modifications were primarily required in the para-aortic and common iliac region for nodal CTV. Multivariable analysis showed that major modifications were associated with the use of extended field radiotherapy and use of radical radiation in non-cervical primaries. ConclusionAn on-demand peer review system was feasible and resulted in clinically meaningful changes in 53% of patients.
Diagnostic Techniques in the Pandemic
Authors: Castillo Nicolas
Published: November 2022

Coronaviruses (CoV) are a group of enveloped, single-stranded (positive-sense) RNA viruses belonging to the nidoviral order, family Coronaviridae. They are an important family of pathogens that affect the human respiratory system can produce clinical pictures ranging from the common cold, with seasonal pattern in winter, to more serious ones such as those produced by severe acute respiratory syndrome (SARS) and Near East respiratory syndrome (MERS-CoV) viruses and the latter responsible for the great global pandemic, SAR-Cov2, which causes the COVID-19 disease that has spread worldwide with very efficient transmission and a higher case fatality rate than seasonal influenza. Diagnostic tools for the detection and monitoring of COVID-19 have become an indispensable requirement to quantify the number of cases around the world and from this point to be able to take the corresponding sanitary and political measures to give a forceful response to the outbreaks that are appearing. Testing is vital clinical diagnostic tool, and the techniques available so far have been based on detection of viral genes (such as RT-PCR reference technique), detection of antibodies and detection of viral antigens.Diagnosis has enormous potential in the fight against diseases and in obtaining better health outcomes in the population. The Covid-19 pandemic focused on the preparedness needed to assess, analyze and identify the different variables of health care. With the extensive use of quantitative reverse transcription-PCR (RT-PCR) technology, it is now possible to provide accurate and timely laboratory diagnostic test results to public health experts and other stakeholders in a robust manner. This contrasts sharply with the last influenza pandemic in 2009, in which diagnosis in many clinical settings was based primarily on clinical observations, resulting in an underestimation of the actual number of deaths caused by pandemic influenza A (H1N1) 2009 virus.Several studies worldwide show that diagnostic tests are an indispensable tool in clinical practice. First, because they provide critical information at every step of the patient pathway: from prognosis, preventive studies (screening), diagnosis to monitoring disease progression and predicting responses to treatment. And also because they play an increasingly important role in providing personalized, cost-effective, value-based healthcare. Even so, the value of diagnostic information is often not fully recognized by health systems. Diagnostic research and development helps develop products and solutions that lead to more patient-centered, outcome-based care. This helps enable healthcare professionals to make the right diagnoses at the right time.
Generalizability of control across cognitive and emotional conflict
Authors: Straub Elisa , Schiltenwolf Moritz , Dignath David , Kiesel Andrea
Published: November 2022

People can learn to control their thoughts and emotions. The scientific study of control has been conducted mostly independently for cognitive and emotional conflicts. However, recent theoretical proposals suggest a close link between emotional and cognitive control processes. Indeed, mounting evidence from clinical sciences, social and personality psychology and developmental neuroscience suggests that the ability to control thoughts and behavior goes hand in hand with the ability to control emotions. Yet, the precise interface between control over cognition and emotions remains controversial. The present study investigates the question whether control is a ´general-purpose´ mechanism or rather a set of domain-specific mechanisms. Following previous research, we tested participants’ control in a cognitive and an emotional Stroop task and assessed the Congruency Sequence Effect which has been taken as a marker of cognitive or (implicit) emotional control, respectively. Going beyond previous research, we asked how control in one domain (e.g., cognitive) interacts with control in the other domain (e.g., emotional) on a trial-by-trial basis. Four experiments (N = 259) presented participants with a task-switching design that intermixed cognitive and emotional conflicts. This procedure produced significant Congruency Sequence Effects across cognitive-emotional domains, suggesting that control can interact across domains. However, effect sizes of within-domain Congruency Sequence Effects were twice as large, indicating that control is also domain-specific. These results neither support the ´general-purpose´ account nor the domain-specificity hypothesis of control. Rather, a hybrid account fits the data best, which also reconciles previous behavioral and neurophysiological findings, suggesting domain-general and specific processes.
Too old to be a diversity hire. Choice bundling shown to increase gender-diverse hiring decisions fails to increase age diversity.
Authors: Jolles Daniel , Juanchich Marie , Piccoli Beatrice
Published: November 2022

Past research has shown that people are more likely to make the decision to hire candidates whose gender would increase group diversity when making multiple hiring choices in a bundle (i.e., when selecting multiple team members simultaneously) compared to making choices in isolation (i.e., when selecting a single team member). However, it is unclear if this bundling effect extends to age diversity and the selection of older candidates, as older workers are often the target of socially-acceptable negative stereotypes and bias in recruitment, leaving them unemployed for longer than their younger counterparts. Across four preregistered experiments (total n = 2,624), we tested if the positive effect of bundling on group diversity for women extends to older workers. We find evidence of bias against older job candidates in hiring decisions and demonstrate that choice bundling fails to increase the selection of older candidates. We discuss the theoretical implications and need for greater understanding of age as a diversity characteristic to support the design of interventions that meet the challenges of an aging workforce.
More than two intuitions

We consider an underdeveloped feature of De Neys’s model. Decisions with multiple intuitions per option are neither trivial to explain nor rare. These decision scenarios are crucial for an assessment of the model’s generalizability and adequacy. Besides monitoring absolute differences in intuition strength, the mind might add the strengths of intuitions per choice option, leading to competing and testable hypotheses.
Does it Matter if Sport Fans “Root for the Home Team”? A Test of the Team Identification – Social Psychological Health Model
Authors: Schellenberg Benjamin J. I. , Gaudreau Patrick
Published: November 2022

The team identification-social psychological health model outlines that fans of local sport teams are more likely to experience feelings of social connectedness compared to fans of distant teams. We tested this proposition across two sufficiently-powered studies. In both studies, sport fans (Study 1 N = 291, Study 2 N = 430) completed online surveys assessing their levels of identification with a favorite sport team and social connections derived from their fandom for that team. Team localness was operationalized based on team location (Study 1) or responses to survey questions assessing team localness (Study 2). In both studies, the positive association between team identification and social connectedness was not moderated by team localness. This research contributes to the TI-SPHM and to our general understanding of fan behavior by showing that the social benefits of being a highly identified sport fan are not limited to fans of local teams.
Teaching Without Thinking: Negative Evaluations of Rote Pedagogy
Authors: Bass Ilona , Espinoza Cristian , Bonawitz Elizabeth , Ullman Tomer David
Published: November 2022

When people make decisions, they act in a way that is either automatic ("rote"), or more thoughtful ("reflective"). But do people notice when others are behaving in a rote way, and do they care? We examine the detection of rote behavior and its consequences in U.S. adults, focusing specifically on pedagogy and learning. We establish repetitiveness as a cue for rote behavior (Exp. 1), and find that rote people are seen as worse teachers (Exp. 2). We also find that the more a person’s feedback seems similar across groups (indicating greater rote-ness), the more negatively their teaching is evaluated (Exp. 3). A word-embedding analysis of an open-response task shows people naturally cluster rote and reflective teachers into different semantic categories (Exp. 4). We also show that repetitiveness can be decoupled from perceptions of rote-ness given contextual explanation (Exp. 5). Finally, we establish two additional cues to rote behavior that can be tied to quality of teaching (Exp. 6). These results empirically show that people detect and care about scripted behaviors in pedagogy, and suggest an important extension to formal frameworks of social reasoning.
'NOT A REAL PROSTITUTE’: NARRATIVE IMAGINATION, SOCIAL POLICY AND CARE FOR MEN WHO SELL SEX
Authors: Henriksen Theresa Dyrvig , Andersen Ditte , Presser Lois
Published: November 2022

The dominant cultural narrative of sex-selling involves female sellers and male buyers, consistent with governing notions of sexual desire and sexual performance more generally. Likewise, needing and receiving care is conventionally coded as feminine. Analysis of semi-structured qualitative interviews with 21 cisgender male sex sellers in Denmark leads us to consider how storylines and discursive boundaries having to do with sex work, sexuality, gender, and care shape narrative imagination in ways that inhibit the participation of male sex sellers in programs that provide the kind of care they may need. Respondents described different experiences of and pathways into sex work. However, both respondents who enjoyed selling sex as well as respondents who suffered found it difficult to imagine themselves as participants in service-providing programs. Rather, they deemed programs designed to provide care and support to sex sellers the exclusive province of women. The paper clarifies the importance of cultivating narrative imagination among male sex sellers, policymakers and care providers in order to develop and deliver more adequate policies and effective programs for male sex sellers in need of care.

This study aims to capture students’ profiles in terms of using video-teleconferencing (VTC) applications and to identify students’ perspectives on using the video-teleconference applications as a platform for English teaching and learning during the pandemic in the English department in Universitas Riau. This mixed-method study collected data from semi-structured interviews and an online questionnaire. The entire sophomores of the English Study Program of Riau University (n=39 students) were taken as the samples of the research. An analysis model from Miles & Huberman (2007) was used as the method to analyze the collected data. The results show that the majority (56.4 %) of the students used a mobile phone as a learning device and 59% of them relied on their own internet data for learning. The students had both positive and negative perspectives on the VTC applications. Most students thought the VTC-based learning was efficient for them. However, they reported some problems such as an unsupportive learning environment, lack of equipment, and unreliable internet connections. These problems imply that universities should provide more learning facilities for students to make online learning more effective.

Internet virtual classes as a substitute for face-to-face learning are becoming common use in schools during the pandemic, which activities outside the home is restricted. SMP Tunas Bangsa has an internet hotspot to access Zoom as a virtual class while browsing activities carried out by the teachers. Diverse activities and high traffic loads cause internet traffic congestion and frequent connection failures. The hotspot requires bandwidth management and access restrictions in order to efficient internet usage. Bandwidth management is carried out by the method Per Connection Queue (PCQ), and access restrictions are carried out with the firewall mangle. Mikrotik router OS configuration in practice manages bandwidth starting with connection marks and packet marks to separate connections to the router, through the router, and from the router to the internet. The parameter used to distinguish the traffic is the IP address which is grouped in dst-address and src-address to fulfill the pcq-classifier. Meanwhile, the blocking of access to streaming activities and online games is intended so the teachers only access related to education matters. To determine the success of the configuration, the Quality of service was calculated both before and after configuration. The results of the QoS throughput parameter which increased from 4.39% to 84.99%, the delay decreased from 462.52 ms to 146.87ms, and packet loss decreased from 27.94% to 0% on the network.
Maintenance of Bilge Pump on Ship Trawl SPL IX Owned PT. Sinar Pesona Laut
Authors: Saridu Muhammad Al Mu'Min , Ziliwu Boby Wisely
Published: November 2022

A pump is a machine or device that raises liquid from a low surface to a higher surface or moves liquid from a low-pressure to a high-pressure area. A centrifugal pump is a machine or equipment used to provide energy to a fluid (liquid) based on the centrifugal force generated by a rotating impeller. So that the liquid can be moved or moved from one place to another. As it receives energy through the impeller, the fluid velocity will increase. This kinetic energy is then converted into compressive energy by the pump housing (casing) in the form of a spiral (volute) or a centrifugal pump or fixed blades (diffuser) surrounding the impeller so that the liquid exits the pump at a high speed. The maintenance method for the bilge pump auxiliary machine is carried out in 6 stages, namely, the first stage opening the filter box, the second stage removing the inner filter and filter box cover gasket, the third stage installing new anti-rust on the inside of the filter box cover, the fourth stage removing the box filter connecting faucet and the bilge pump pipeline, the fifth stage opens the connection of the pipe and the bilge pump, the sixth stage ensures that all components of the bilge pump are firmly installed and perform operational test

Published: November 2022

Turmeric (Curcuma longa) contains curcumin that can be used to improve the health as well as the immune system of the fish. The health and immune system condition of the fish can be predicted based on the hematology of the fish. A study that aims to understand the effects of turmeric addition in fish feed pellets on the hematology condition of common carp has been conducted from March to May 2022. The turmeric powder was mixed well with the feed pellets and the dosages of the turmeric powder were as follows: 0 (Control, no turmeric addition), P1 (0.5 g/kg), P2 (1 g/kg), and P3 (1.5 g/kg). The fish was reared in circular plastic containers (25 L), completed with an aerator and circulation pump) for  49 days, 15 fish/ container. During the research, the fish was fed 3 times/ day, at satiation. Samplings were conducted 2 times before the treatment was applied and by the end of the experiment (the 49th day). Results show that the addition of turmeric powder in the fish feed pellets clearly affects the hematological of the fish. Fish that was fed with turmeric-enriched pellets showed a higher percentage of lymphocyte and which means that the immunity of the fish is improved. The best treatment P3 showed 81.55% lymphocyte, 6.55% monocyte, 5.44% neutrophil, and 5.44% thrombocyte. Data obtained indicate that the fish fed with turmeric pellets perform better in hematological conditions than the fish with no turmeric-enriched pellets.

Published: November 2022

The Palu-Donggala earthquake that occurred on September 28, 2018 caused additional disasters in the form of liquefaction and tsunami. The tsunami that hit the coastal area of Palu Bay caused considerable damage, indicating a change in the coastline. The purpose of this study was to determine the changes in the coastline that occurred in Palu Bay, Palu City, Central Sulawesi as a result of the Tsunami. The data used in this study are Sentinel 1 satellite imagery before and after the Tsunami occurred. The coastline at each time is obtained from the extraction of Sentinel 1 satellite imagery. Analysis of shoreline change uses quantitative descriptive techniques with the help of the DSAS tool with change analysis based on the Net Shoreline Movement (NSM) method which is integrated with ArcGIS software. The results show that there has been a significant change in the coastline in Palu Bay, Palu City, Central Sulawesi. Coastline changes that occur are in the form of abrasion and accretion conditions, but are more dominated by abrasion.

Narrow barred Spanish mackerel and wolf herring is an important commodity that has commercialized intensively to fulfill the needs of the market, both domestic and export. Research has been conducted from June-August 2020 in Malacca Strait Waters. The purpose of this study is to analyze the dynamics of population parameters such as growth rate, mortality rate, exploitation rates, and recruitment patterns of narrow barred mackerel (Scomberomorus commerson) and wolf herring (Chirocentrus dorab). The sample size of spanish mackerel was taken at random from the purse seiner and gillnet catches. Data of size obtained were used for the analysis of population dynamics parameters. Some population dynamics parameters were estimated using the program FISAT II. Von Bertalanffy growth parameters of spanish mackerel were derived L and growth rate (K),for males 772.8 mm and 0.5/year and for females 979.65 mm and 1,7/year, and wolf herring was derived L and growth rate (K), for males 871.5 mm and 0.59/year and for females 1048.95 mm and 0.65/year, respectively. Total mortality (Z) of Spanish mackerel males and females was 0.61/year and 4.07/year and wolf herring males and females were 0.36/year and 1,3/year. Fishing mortality rate of Spanish mackerel (F) for males and females was 0,13/year and 3.07/year high than the natural mortality rate (M) 0.48/year and 1/year and the wolf herring fishing mortality rate for males and females was 0.16/year and 0.78/year lower than natural mortality rate (M) 0.52/year. Exploitation rate (E) of Spanish mackerel for males and females was 0.21/year and 0.75/year and wolf herring for males and females was 0.44/ year and 0,6/year, that almost full exploitation when compared with the optimum of 0.40. The recruitment pattern of Spanish mackerel for males was (14.59%) in June and for females was (26.84%) in August and wolf herring for males was (16.02) in June and for females was (28.63%) in July.

Kranji waters have potential fishing grounds for the development of large marine fisheries. Kranji fishermen often face obstacles in their fishing efforts due to a lack of information about the season and potential fishing areas. The oceanographic factor of the waters can be one of the clues to determining a good catch. The purpose of this study was to determine the condition of the oceanographic parameters of the fishing area, determine the catch rate and determine the correlation of oceanographic parameters to the catch of ring trawlers. The data used in this study were temperature, salinity, depth, current velocity and catch for 10 fishing trips. Oceanographic parameters in the Kranji fishing area for 10 fishing trips were as follows: temperature ranged from 29.9- 31.8°C, water salinity ranged from 29-31.1‰, water depth ranges from 50-70 m and the current velocity ranges from 0.09to 0.34 m/s. The variability of ring trawl production during 10 times of capture found 5 species caught. The variability and composition of purse seine catches were as follows: Tongkol Walang with a percentage of 54.42%, Tongkol Lorek with a percentage of 38.13%, belo fish with a percentage of 6.37%, juwi with a percentage of 0.53%, and the lowest. the percentage is bagong by 0.52%. The correlation of oceanographic parameters with purse seine catches is as follows: Current velocity has the highest correlation value with a correlation coefficient of 0.814. The temperature has a strong category value with a correlation coefficient of 0.756. Salinity has a negative correlation value with a value of -0.658. Depth has a strong category value with a correlation coefficient value of 0.657.
