Performance of three generations of Asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840) domestication result of nursery phase one
Authors: Kusmini Irin Iriana , Radona Deni
Published: August 2019

In order to the success of domestication programs of Asian redtail catfish is necessary to evaluate the level of change in each generation produced. This study aimed to evaluate the performance of growth and survival rate on three populations from each generation spawned of Asian redtail catfish (G-1, G-2 and G-3). The study was conducted experimentally used completely randomized design (CRD) with 3 treatments and 3 replications from May to July 2017. The origin of the post larvae of Asian redtail catfish was the modified seeds from mass spawning of Asian redtail catfish of Cirata population. G-1 was the population resulted from the spawning of the oldest broodstock, G-2 was a population resulted from spawning  of the first generation broodstock and G-3 was the resulted from spawning of the second generation broodstock. Spawning process was conducted in the same time. The age of the seeds was one week old after hatching with total length of 0.8-1.0 cm and body weight of 0.0082 ± 0.0001 g. The Asian redtail catfish seeds were reared in the aquarium with dimension of 70 cm 50 cm x 40 cm and equipped with recirculation system. Each aquarium was stocked seed with a density of  2,000 individual 100 L-1 of water. During rearing process (15 days), fish were fed at satiation with frequency of three times per day.  Feed was adjusted to mouth opening of larvae. Initially, larvae on 1 to 7 days of rearing process were fed with artemia and after that fed with tubifex. The result showed that the highest growth and survival rate performance (P<0.05) were obtained in Asian redtail catfish seed (G-3) with a value of 1.64 ± 0.02 cm and 53.42 ± 8.86%, respectively. Postlarvae of Asian redtail catfish from third generaton of domesticated (G-3) can increase fish productivity.

The quality of feed can be improved by fermenting feedstuffs and supplementing with feed additives. This study aims to determine the effect of supplementation of Lumbricus sp. extract in fermented feed on growth performance, body chemical composition, and milkfish hepatosomatic index. Milkfish with an initial weight of 17.80 ± 0.20 g head-1, rearing with a density of 20 fish per hapa net measuring 1 m3 by 24 pieces. Hapa net is installed in a pond with a water level of ± 60 cm. Research was design in completely randomized design with two factors. The first-factor was supplementation method, namely Lumbricus sp. which sprayed on feed and mixed with feed ingredients. The second factor was the dose of Lumbricus sp. extract, namely 0, 100, 200 and 300 mL kg-1 of feedstuffs. The fish was reared for 50 days and fed with 5% of fish biomass per day with feeding frequency of 3 times i.e., morning, afternoon and evening. The results showed that the supplementation Lumbricus sp. extract has no significant effect on all parameters (P>0,05).  However, the level dose of Lumbricus sp. extract supplementation in feed has a significantly effect (P<0.05) on absolute growth, relative growth, feed efficiency, and hepatosomatic index, but no significant effect (P>0,05) on survival and chemical composition of milkfish body. The best best of absolute growth (16.94±4.0 g), relative growth (48.71±5.77%), feed efficiency (40.74±10.3 %), and hepatosomatic index (1.5 ± 0.17) were found in the experiment of supplementation Lumbricus sp. extract mixed with feedstuffs at a dose of 300 mL kg1.

Color blindness test is one way to find out whether a person has color blindness or not, is usually done with the Ishihara method. This Ishihara method is a method where when running a test with this method, the patient is usually faced with a book containing a circle pattern (disk) with many points of various colors and sizes in it. The circle pattern is usually 14, 24 and 38 dishes. Tests like this are usually done in health agencies, one of which is the Cahaya Insani Clinic in Garut, West Java. The process of implementing a color-blind test is still done manually where people who want to do a color-blind test must come directly to the clinic, making people who did color-blind tests had to be willing to wait a long time to be able to do a color-blind test. In addition to these problems, the lack of knowledge and understanding of the community regarding color blindness, makes people less aware of the importance of color-blinding tests early on. Therefore, a media is needed that can do color blindness tests quickly and easily, coupled with information about color blindness that can provide insight to the community. Mobile based application Android is one of the right media to make it easy for people to obtain information. Starting from this, then made an Android-based color blindness test application to make it easier for people to do color blindness tests anytime and anywhere, and can used as a medium of information about color blindness.

Authors: G. Varela Daniella , Kupczynski Lori , Mundy Marie-Anne
Published: August 2019

Despite a healthy production of teachers, teacher attrition is a significant concern facing school administrators across the state of Texas. This study sought to determine the extent to which questions on the Exit and Principal Surveys reflect three sets of standards which guide educator preparation in Texas: Association of Teacher Educators (ATE) Standards for Teacher Educators, Texas Administrative Code (TAC) Educator Preparation Program Curriculum Standards, and Pedagogy and Professional Responsibilities (PPR) Exam Standards. This analysis provides important information about the validity of survey questions as a measure of standards compliance for educator preparation in Texas and also sought to determine if there is a difference between teacher candidates’ Exit Survey evaluation of preparation and principals’ Principal Survey evaluation of first-year teachers’ preparation. Findings indicated a clear disconnect. Recommendations are provided as contributions for future discussion on much needed educator preparation program standards reform.
The Role of Control Motivation in Germans’ and Poles’ Interest in History

Published: August 2019

Contemporary societies seem to be obsessed with history. This is reflected in the popularity of historical books, films, and reenactments. In our research, we aimed to assess the specific types of content that interest people when exploring their national histories and the psychological factors motivating such explorations. Following the two-dimensional model of social cognition that points to morality and competence as the main dimensions in individual and group perception, we distinguished interest in competence-related aspects of national history (control) from interest in historical moral actions (moral agency). Two studies performed in Poland and Germany showed that in both countries people’s interest in history is structured in a similar way, in which moral agency and control play essential roles. Additionally, in both countries people reacted to individual control threats with enhanced curiosity about the past moral agency of their nations. We discuss these results within the framework of the model of group-based control and compensatory control processes.
Stereotype Content as a Collective Memory of Place and Its Past Intergroup Relations
Authors: Winiewski Mikołaj , Bulska Dominika
Published: August 2019

The stereotyped content of outgroups denotes intergroup relations. Based on this notion, Susan Fiske and colleagues (2002, https://doi.org/10.1037/0022-3514.82.6.878) created the stereotype content model (SCM), which links two dimensions, warmth and competence, with social structure. The structure of intergroup relations is not stable in time, nor is it shaped instantly. Based on the assumptions of SCM we predict that the history of intergroup relations is in part responsible for stereotypes. In order to test the hypothesis we reanalysed five Polish nationwide, representative surveys (total N = 4834). The studies followed a similar procedure for data collection, and each study asked an open-ended question about the traits of two ethnic groups (Jews and Germans). Answers were listed and coded using competent judges. The averages of the judges’ codes were used as indicators of stereotype content and an analysis of regional differences was conducted. Several significant results were obtained and are interpreted in line with warm – competition and competence – status relations. The results show that several historical situations and events, such as pre-WWII social structure or post-war migrations and territorial changes, can be linked to contemporary stereotypes.
Understanding How and Why Spatial Segregation Endures: A Systematic Review of Recent Research on Intergroup Relations at a Micro-Ecological Scale
Authors: Bettencourt Leonor , Dixon John , Castro Paula
Published: August 2019

Social psychological research has increasingly extolled the benefits of intergroup contact as a means of promoting positive relations. However, a growing body of research suggests that formal policies of desegregation are often offset by informal ‘micro-ecological’ practices of (re)-segregation, in everyday life spaces. This paper presents a systematic literature review of recent evidence on this topic (2001-2017), outlining key findings about how, when, where, and why micro-ecological divisions are reproduced. Informal segregation can happen based on ethnicity, religion, socioeconomic status, gender, or gender and ethnicity, despite people being in a shared place. People generally maintain patterns of ingroup isolation as a result of: a) negative attitudes and stereotypes; b) ingroup identification and threat; or c) feelings of anxiety, fear and insecurity. Educational settings have been the main context studied, followed by leisure and recreational places, public urban places and public transport. The paper also identifies three areas of potential future research, highlighting the need to: (1) capitalise on methodological innovations; (2) explore systematically how, when and why the intersectionality of social categories may shape micro-ecological practices of contact and separation; and (3) understand more fully why micro-ecological patterns of segregation are apparently so persistent, as well as how they might be reduced.
Residential Satisfaction, Psychological Well-Being and Perceived Environmental Qualities in High- vs. Low-Humanized Residential Facilities for the Elderly

Published: August 2019

Using the “user-centered” design perspective and the construct of design “humanization” as theoretical underpinnings, this field study verified the role of “objective” design quality of residential facilities for the elderly in the prediction of “subjective” users’ psychological responses. A sample of over-65-year-old adults (N = 114) was recruited in eleven residential facilities, which differed for the degree of “objective” design humanization (rated on the basis of a design expert assessment). Participants had to fill in a questionnaire including measures of both specific perceived environmental qualities (spatial-physical and social-relational) and more general psychological responses (such as residential satisfaction and psychological well-being). Outcomes revealed that older residents living in high-humanization structures show higher scores of residential satisfaction, psychological well-being and perceived environmental qualities than those living in low-humanization structures. Moreover, significant correlations emerged between specific perceived environmental qualities of the facility and general psychological outcomes. These results confirm the importance of design features for supporting elders’ needs and fostering their quality of life.
LASHING IN QANUN ACEH AND THE CONVENTION AGAINST TORTURE: A CRITICAL APPRAISAL
Authors: Muhammadin Fajri Matahati , Wicaksono Dian Agung , Sari Almonika Cindy Fatika , Ayutama Ola Anisa
Published: August 2019

While considered archaic to some, the Islamic Sharia applies lashing as punishment for a number of penal offences. Aceh is a special province in Indonesia with the privilege to apply some level of Islamic Sharia. Among them is to apply lashing as punishment for crimes such as fornication, gambling, consuming alcoholic beverages, and many others. Some have criticized this punishment as a violation of the prohibition against torture and cruel treatment. Based on a mix of normative and empirical research, his article will explore the relevant sources of international law and examine whether or not such a claim is true. It will be found that the Islamic Sharia version of lashing as applied in Aceh does not violate this prohibition, except in a very narrow-minded view of international law which may be an intellectual legacy of colonialism towards the world.

CAPILLARY AND MICROCIRCULATION STRUCTURE OBSERVED IN ABORIGINES AND NORTH-BORN CAUCASOIDS RESIDENTS OF RUSSISA’S EXTREME NORTH-EAST
Authors: Maksimov A I , Kharin A V
Published: August 2019

The results of the comparative analysis of morphofunctional parameters in naiL-bed skin fold capillaries in male Aborigines and north-born Caucasoids (residents of Chukotka Autonomous District) examined at rest and rerespiration test are presented in the paper. The intravital study of capillary morphometric structure and erythrocyte motion speed in arterial and venous circulation was carried out using "Capillaroscan-01" complex developed in Skolkovo innovation centre. It was found out that the structure and characteristics of microcirculation in Aborigines differed significantly from those in Europeans North natives in the 1st-2rd generation. Aborigines of Chukotka Autonomous District, as compared to Caucasoids of the same age, demonstrated bigger diameter of the arterial link at higher blood flow speed that set better conditions for erythrocyte laminar motion. Besides, it turned out that, short-term rerespiration test in confined space without carbon-dioxide adsorption, despite the evident hypoxic-hypercapnic effect, did not influence morphofunctional parameters of microcirculation of the surveyed. Apparently, the capillary microcirculation structure specific for Aboriginals provided the body surface temperature maintenance and heat conservation much better than in Caucasoids born in the north and living in the same climatic conditions.

By means of enzymoiimmunoassay and flow cytofluorometry the effect of carbon monoxide and ultraviolet (UV)-light on the expression level of the receptor complex molecules (CD95 and CD8 markers) on the membranes of human blood lymphocytes has been studied. It was stated that the carbon monoxide causes decrease of CD95 receptors on the surface immune cells during (60 ^ 90 min). However, strengthening of this effect was registered in 24 hours. It is shown that UV-light in 453 and 755 J/m2 doses provides the pro-apoptotic effect as related to the expression level of CD95 receptors of analyzed cells. After daily thermostating of modified lymphocytes, different receptiveness of CD8 molecules to carbon monoxide was revealed. Thus, in patients with initially higher levels of CD8 markers - decrease is registered, and in individuals with initially low - increase in this marker levels. The obtained data of blood lymphocytes receptor profile changes in the presence of low molecular ligand (CO) must be taken into account in the Ultraviolet Blood Irradiation-therapy in patients with different etiologies.

Study of the relationship between ventilation parameters: monitored expiratory time constant – τedyn and breathing – trigger frequency (ftrig) and time of breathing cycle (Tcy) are main goals of this article. Parameters were analyzed during last 4±2 h before weaning from ventilation in 66 patients ventilated in pressure support mode (PSV). We have found out, that there exist mathematical relationships, observed during adequate gas exchange, yet not described. Monitored parameters are represented by τedyn, ftrig and Tcy. The analysis showed close negative correlation between Tcy and ftrig (R2=0.903). This implies that each increasing of τedyn causes decreasing of ftrig and vice versa. The calculation of regression equation between τedyn and Tcy outlined that Tcy = 5.2625 * τedyn + 0.1242 (R2=0.85). Regulation of respiratory cycles by the respiratory center in the brain is probably based on evaluation of τedyn as the τedyn probably represents a regulatory element and Tcy regulated element. It can be assumed, that respiratory center can optimize the work of breathing in order to minimize energy in system patient + ventilator. The unique relationship, described above could be useful in clinical practice for development of new ventilation modes.

Hepcidin is a key regulator of iron metabolism and plays an important role in many pathologies. It is increased by iron administration and by inflammation, while erythropoiesis downregulates its expression. It decreases iron availability and thus contributes to anemia of chronic diseases. The aim of the study was to measure hepcidin as a marker and pathogenetic factor in ANCA-associated vasculitis (AAV). Hepcidin plasma concentration was measured by the immunological method in 59 patients with AAV and compared to patients with non-vasculitic etiology of chronic kidney disease, patients on hemodialysis (HD), with systemic lupus erythematodes (SLE) and to healthy controls and blood donors, and was correlated with the parameters of iron metabolism, inflammation, activity of the process and kidney function. Hepcidin concentration was increased in patients with AAV, SLE and HD and correlated positively with C-reactive protein, serum ferritin and creatinine, and negatively with hemoglobin and serum transferrin. In active form of AAV it correlated with the clinical scoring system (BVAS). Hepcidin can thus be considered as a pathogenetic factor of anemia in AAV and can be used for evaluation of inflammation in AAV and as an additional marker in active forms of the disease.

One reinforced beam element that experiences a shear failure is a high beam; a beam that follows a requirement based on SNI-2847-2013 standard that have the proportion of sliding span (l) and the effective height (d) not more than three. The type of collapse in high beams generally is shear failure in which the crack appears from the area around the placement, propagates and reaching the maximum value at the point of loading. Observation of crack patterns and ultimate loads can be done by several methods based on both non-linearity and linearity of materials.

Two specimens consisted of one high beam conventional reinforced concrete and one high beam concrete fiber with a dimension of 170 mm x 420 mm x 850 mm were prepared. Fiber from machine turning waste was used as coarse aggregate substitution with 100% composition in fiber concrete. Both specimens were tested in the laboratory and observed for crack patterns analysis and ultimate load achievement. The experimental test results were then compared with the numerical test results for the non-linearity properties of the material and the Strut and Tie method for the linearity properties of the material.

The ultimate high beam of conventional reinforced concrete when experiencing shear failure in the experimental method, numeric method, and strut and tie method were 310 KN, 290 KN, and 236.917 KN respectively,  whereas in the high beam fiber concrete, the ultimate load in the experimental method, numeric method, and in the strut and tie method were 280 KN, 260 KN, and 263,917 KN respectively. The biggest ratio of test results were obtained from the comparison between the numerical and the experimental methods in conventional concrete which was equal to 0.94. This showed the similarity of non-linearity properties of the material to produce adjacent test results.

The collapse of a column causes the collapse of the entire building that need a large cost for repairing. Therefore, special attention is needed when planning the columns, i.e. by providing a backup strength on columns which greater than other beams and other horizontal structural elements since there is no initial warning in a press-type of collapse. This study aims to determine the efficiency of square concrete column dimensions in case of column calculations after the revision of PBI 1971 to SNI 1991 standard both by manual calculation and using the Turbo Pascal-based application.

Calculation utilized the elastic method and ultimate method with the assumption that column conditions are similar as well as the column data is taken from the calculation of reinforced portal structures. Concrete columns are made rectangle with dimensions of size 35 x 35 cm and size 75 x 75 cm, concrete quality K 225, steel quality U24 (2400 kg / cm²), modulus of steel elasticity 2.1. 10⁶ kg / cm² and 5 cm thick of concrete blanket, with the assumption that structural analysis has been conducted for calculating the boundary and moment loads, assuming that the column conditions are similar.

In case of the ability to retain the load and moment by the column, assuming the constant area of ​​reinforcement in various dimensions, the results of the elastic method (PBI 1071) were smaller than the ultimate method (SK SNI 1991). The calculation results showed that the ultimate method was more efficient than the elastic method in terms of the efficiency of reinforcing steel use.

Nowadays, delays in project often occur and cause various losses both for service providers and users. For the contractors, delays create the project cost overruns due to project overtime and can decrease contractor credibility in the future. This study aims to analyze a project delay by minimizing the work delays earlier. The analysis of a hotel building planning regarding the cost and time delays is done qualitatively by distributing questionnaires to the contractors and processing the responses using the SPSS software. The results of the S curve analysis and 30 factors that caused the project delay were identified and indicated that there was a delay value of 1.26% with five variables that most contributed to the delay in the construction project at PT. Wijaya Kusuma Contractors, i.e. reworking due to construction errors, low coordination between contractors and stakeholders, late material delivery, and equipment shortages.
