Authors: Laksana Dek Ngurah Laba , Seso Maria Angelina 
Published: August 2019

Tujuan dari penulisan ini adalah untuk mengembangkan desain pembelajaran kontekstual spirit meda mazi di kelas rendah. Model pembelajaran kontekstual merupakan pembelajaran yang dilakukan oleh guru, untuk mengaitkan antara materi yang diajarkan dengan situasi dunia nyata siswa dan mendorong siswa membuat hubungan antara pengetahuan yang dimiliki dengan penerapannya dalam kehidupan mereka sehari-hari baik lingkungan pribadi, sosial dan budayanya. Spirit meda mazi merupakan ungkapan dalam bahasa Bajawa yang artinya duduk bersama untuk membicarakan sesuatu yang bermanfaat (bermusyawarah). Pengumpulan data penulisan ini dengan pendekatan deskriptif melalui wawancara, observasi dan riview literatur. Berdasarkan wawancara yang dilakukan dengan para guru di SDI Malanuza, bahwa dalam implementasi penerapan model pembelajaran kotentekstual yang berbasis spirit meda mazi guru masih mengalami kesulitan, yaitu dalam mengkaji materi. Karena tidak semua materi pembelajaran dapat diterapkan dengan menggunakan model pembelajaran ini. Model pembelajaran yang berbasis kontekstual spirit meda mazi saat ini baru diterapkan di dua Kecamatan yang ada di Kabupaten Ngada yaitu Kecamatan Golewa dan Kecamatan Golewa Selatan khususnya di sekolah dasar. Pembelajaran yang berbasis kontekstual spirit meda mazi ini dikembangkan berdasarkan hal-hal yang berkaitan dengan pelajaran di sekolah dengan hal-hal yang dipelajari di lingkungan masyarakat. Pembelajaran yang berbasis kontekstual spirit meda mazi yang diterapakan di kelas rendah sangat membantu guru pada saat menjelaskan materi pelajaran. Karena pada pembelajaraan guru dapat menggunakan bahasa keseharian siswa yaitu bahasa daerah yang dapat membantu guru untuk menjelaskan materi sehingga siswa dapat lebih mudah untuk memahami materi yang diajarkan.

Published: August 2019

Abstract
The objective of the present study was to determine the seasonal changes in boar semen quality by the assessment of sperm membrane integrity, analysis of chromatin structure, assessment of oxidative stress and of apoptotic changes in spermatozoa. Semen from 16 boars (172 ejaculates) was investigated. The males were aged between 7 months and 7 years. Semen was extended with BTS diluent and stored at +17°C. During seven days of storage, the semen was subjected to standard evaluation and novel methods for semen assessment. In the autumn-winter period, the semen had higher evaluations than in the spring-summer period, but only sperm membrane integrity examination showed significantly lower (P≤0.01) percentage of moribund spermatozoa and the semen had a significantly (P≤0.05) lower (by 0.5%) percentage of sperm with damaged chromatin. Examination performed after 7-day storage showed significantly (P≤0.01) higher percentage of live spermatozoa and with high mitochondrial membrane potential for the autumn-winter period. The level of apoptotic cells was significantly (P≤0.01) lower for the autumn-winter period. Examination of sperm membrane integrity after 7 days of storage showed a lower (P≤0.05) percentage of moribund spermatozoa for the autumn-winter period. In our opinion, novel methods for sperm assessment may be used to monitor new parameters of sperm function.

Published: August 2019

Abstract
The aim of this study was to test the effect of the animal to feeding place ratio on behavior of meat goats during gestation. In one group (FP-1.0; n=10) every goat had a single feeding place while in the other group (FP-0.5; n=10) two goats had to share one feeding place. Behaviors were analyzed with the continuous sampling method for 24 h for each animal. Social dominance index was used by ranking individuals as low-, medium- and high-ranking according to withdrawal and displacement behaviors. Total daily feeding duration decreased (P=0.001) from 5.2 h to 4.2 h by reducing feeding place. Feeding duration was neither affected by social rank (P=0.362) nor its interaction with feeding place (P=0.159). Feeding frequency was higher in FP-0.5 than FP-1.0 (P=0.001). Low-ranking goats had a higher feeding frequency (P<0.001). Resting duration (lying and standing) decreased in medium- and low-ranking goats in FP-0.5 (P=0.001) while all rank categories were similar in FP-1.0. Competition behaviors increased (P=0.001) in medium- and low-ranked goats in FP-0.5 but were similar between rank categories in FP-1.0. Feeding place and social rank had an effect (P≤0.009) on some of the agonistic behaviors. Agonistic interactions such as displacement, butting and ignoring were affected by the interaction of feeding place and social rank (P≤0.005). In conclusion, the reduction of the number of feeding places from 1.0 to 0.5 per goat in pregnant hornless Boer goats negatively affected feeding, competition, resting and aggressive behaviors, whereas low-ranking animals suffered more from competition and aggression behaviors.
Effects of Soybean Meal Fermented by Lactobacillus Species and Clostridium butyricum on Growth Performance, Diarrhea Incidence, and Fecal Bacteria in Weaning Piglets

Published: August 2019

Abstract
Fermented soybean meal (FSBM) has been widely investigated as a nutritional strategy for reducing the use of fish meal (FM) and antibiotic growth promoters. Microbial fermentation by using bacteria can increase the bioavailability of nutrients and reduce the levels of antinutritional factors in soybean meal (SBM). In this study, we evaluated whether FSBM produced from Lactobacillus species and Clostridium butyricum improves growth performance, diarrhea incidence, and fecal bacteria in weaning piglets. Eighty-four crossbred male piglets with an average initial body weight of 8.36±0.63 kg were randomly allotted to 3 dietary treatments consisting of 7 replicate stalls with 4 piglets each. The dietary treatments were: (1) 3% FM in the diet; (2) 5% FSBM in the diet; and (3) 3% FM in the diet plus 4 mg/kg antibiotic growth promoters (AGP). We determined that growth performance was unaffected in FSBM-fed weaning piglets compared with a FM group. Similar to the AGP group, FSBM supplementation significantly reduced diarrhea incidence in weaning piglets. The number of fecal Lactobacillus species significantly increased in 28-day-old FSBM-fed weaning piglets compared with the other groups. Compared with AGP, FSBM has the highest inhibitory effect on the number of fecal Enterobacteriaceae at 28 d old. Furthermore, serum immunoglobulin G and immunoglobulin A levels in FSBM-fed weaning piglets significantly increased at the same age. These results together indicate that FSBM can replace FM in the diets of weaning piglets without affecting growth performance. Furthermore, similar to AGP, FSBM could improve diarrhea incidence, fecal bacteria, and immunoglobulin levels in weaning piglets. Therefore, SBM fermented by Lactobacillus species and C. butyricum demonstrated high potential for development as swine feed ingredients.
Aldosterone rapidly activates p-PKC delta and GPR30 but suppresses p-PKC epsilon protein levels in rat kidney

Published: August 2019

Abstract

Objectives. Aldosterone rapidly enhances protein kinase C (PKC) alpha and beta1 proteins in the rat kidney. The G protein-coupled receptor 30 (GPR30)-mediated PKC pathway is involved in the inhibition of the potassium channel in HEK-239 cells. GPR30 mediates rapid actions of aldosterone in vitro. There are no reports available regarding the aldosterone action on other PKC isoforms and GPR30 proteins in vivo. The aim of the present study was to examine rapid actions of aldosterone on protein levels of phosphorylated PKC (p-PKC) delta, p-PKC epsilon, and GPR30 simultaneously in the rat kidney.

Methods. Male Wistar rats were intraperitoneally injected with normal saline solution or aldosterone (150 µg/kg body weight). After 30 minutes, abundance and immunoreactivity of p-PKC delta, p-PKC epsilon, and GPR30 were determined by Western blot analysis and immunohisto-chemistry, respectively.

Results. Aldosterone administration significantly increased the renal protein abundance of p-PKC delta by 80% (p<0.01) and decreased p-PKC epsilon protein by 50% (p<0.05). Aldosterone injection enhanced protein immunoreactivity of p-PKC delta but suppressed p-PKC epsilon protein intensity in both kidney cortex and medulla. Protein abundance of GPR30 was elevated by aldosterone treatment (p<0.05), whereas the immunoreactivity was obviously changed in the kidney cortex and inner medulla. Aldosterone translocated p-PKC delta and GPR30 proteins to the brush border membrane of proximal convoluted tubules.

Conclusions. This is the first in vivo study simultaneously demonstrating that aldosterone administration rapidly elevates protein abundance of p-PKC delta and GPR30, while p-PKC epsilon protein is suppressed in rat kidney. The stimulation of p-PKC delta protein levels by aldosterone may be involved in the activation of GPR30.
Testing trade-off theory and pecking order theory under managerial overconfidence
Authors: Bukalska Elżbieta 
Published: August 2019

Abstract
We address our research to the problem of managerial overconfidence and financing behavior. The aim of the paper is, hence, to ascertain the pattern of financing decisions of overconfident managers and identify the relevant capital structure theory (trade-off or pecking order theory) that can be used to explain financing decisions of overconfident managers. We collected a sample of 145 private companies. The degree of overconfidence was distinguished by surveying the managers on overestimation, overplacement, and overoptimism. The financial data covers the period of 2010–2015. We calculated static ratios of capital structure and uncovered the determinants of capital structure. We then unveiled the target debt ratios using Fama and French methodology and identified the difference between target and actual debt ratios. We also calculated the value of deficit and the sources of financing according to Shyam-Sunder and Myers. We found that the companies managed by overconfident managers use higher value of equity and display similar debt ratios. They also utilize reverse pecking order preference—trying to use internal funds and then turning to equity. Moreover, we noted that companies managed by overconfident managers come closer to target debt ratios and implement more risky fixed assets financing strategies. The significance of our research is that we contribute to the understanding of capital structure decisions by taking into account behavioral biases and conducting comprehensive research on both static and dynamic capital structure.
Proto-Slavic Phraseology: Myth or Reality?
Authors: Walter Harry , Mokienko Valery Mikhailovich 
Published: August 2019

Abstract
The reconstruction of the Proto-Slavic vocabulary was and remains one of the priority tasks of comparative-historical Slavic studies. Different approaches to the solution of this problem are demonstrated by the monumental (although not completed) etymological dictionaries of the Proto-Slavic language, the hypothetical existence of which is recognized by most Slavists and Indo-Europeanists. Its reconstruction is performed almost exclusively on lexical material, and attempts to reconstruct the pre-Slavic phraseology are single. The method of such a reconstruction, based on a detailed account of the dialect material, was proposed in 1973 by N. I. Tolstoy. Studies in this direction make it possible to identify a zone of relative generality of Slavic phraseology, which, however, comes into contact with the Baltic and German-speaking zones. Inside such a Slavic massif, sub-zones of East Slavic-Polish phraseological interaction (often associated with the Baltic), West Slavic-Croatian-Slovenian (strongly influenced by German phraseology) and Bulgarian-Macedonian-Serbian (revealing traces of Turkic language influence) are revealed. In this general areal picture, there are many more concrete interactions, for example, a particular language specifics of the phraseology.
Instruments and rules of production and interpretation of a concise text (with special regard to normativity)
Authors: Gahér František , Števček Marek , Braxatoris Martin 
Published: August 2019

Abstract
In the production of concise texts, several instruments are used, of which two can be considered as basic: intratextual referencing (anaphora/cataphora) and the simple or complex ellipsis (ellipsis/syllepsis). However, the use of these instruments affects the unambiguity and intelligibility of the text. Certain rules for and limits to the simplification and shortening of the primary text are needed to secure the possibility of an unambiguous reconstruction of the text by the language user. However, we show that the elimination of homonymy from these texts seems to require considerable skill in the given area. Some such texts may be unintelligible even to informed experts. We delineate some basic cases of application of instruments for the streamlining of texts, with paradigmatic examples from law, including its Anglophone variants. Partly due to the nature of modern English as used in law, Anglo-American linguistics was compelled to formulate, in cooperation with legal theorists, explicit rules for the production and reconstruction of concise texts. By contrast, neither Slovak, nor Czech linguistics offers a self-contained set of such explicit rules. Using examples from law, we therefore propose explicit formulations of several rules which are used implicitly. They are the rule of the last antecedent, the rule of serial antecedents, the rule of the nearest reasonable referent, the rule of the series qualifier, the rule of unchanged topic, the rule of focus development, and the rule of repetition dominance. We argue that in the reconstruction of certain concise legal texts, the syntactic and semantic rules provided by linguistics or logic do not suffice. Therefore, it is necessary to complement them with specific methods of interpretation of legal texts.
