Published: May 2017

In the northeastern part of Brazil, located 90% within the semi-arid region of the country, we can find areas that present quite peculiar characteristics, amongst these the Caatinga. This biome is characterized by the floristic composition formed of dry forest and in this semi-arid environment there is an increase in the supply of resources during the rainy season. This is a region lacking in research, particularly in the State of Paraíba, where no survey studies of social wasp were carried out yet. Social wasps are an important predator of plagues species. The objective of this study was to conduct a survey of the community of social wasps (Polistinae species) that inhabit in the neotropical dry forest of Paraiba, in the municipalities of Sumé and Prata, and to compare the richness and abundance of wasps located in areas of Caatinga with those inhabiting areas intercropping plantation with organic farming. The present study sampled 10 Polistinae species distributed in six genera. Two new species were registered for the state. The comparison between the community of social wasps of the Caatinga There was not statistical difference in the richness and abundance between the natural vegetation and organic intercropping. This means that agroecosystem attracted community of Polistinae, promoting the maintenance of social wasps in anthropic environmental and favoring the biological control.

Authors: Safrida Elysa Nur , Nurani Neti , Julia Madarina
Published: May 2017

Background Central obesity has been associated with a high risk of insulin resistance. Waist circumference and waist-to-height ratio are anthropometric indices for determining central obesity and have been associated with increased blood pressure, cholesterol, and insulin levels. In adults, fat distribution around the waist is a valid predictor of glycated hemoglobin (HbA1c)levels, and is currently recommended by experts as a diagnostic tool for diabetes. Central obesity measurement has advantages over fasting blood glucose and oral glucose tolerance tests, as it is simple and inexpensive to perform.Objective To assess for correlations between HbA1c level and waist circumference as well as waist-to-height ratio and to assess factors potentially associated with HbA1c levels in overweight and obese adolescents.Methods This cross-sectional study was done in four junior high schools in Yogyakarta, which were obtained by cluster sampling. Overweight and obese students who were generally healthy were included in the study. Subjects underwent waist circumference and waist-to-height ratio measurements, as well as blood tests for HbA1clevels.Results Sixty-seven children participated in the study, with 48 girls (71.6%) and 19 boys (28.4%). Waist circumference and HbA1c levels were not significantly associated (r=0.178; P=0.15). However, waist-to-height ratio and HbA1c levels had a weak positive correlation (r=0.21; P=0.04). Linear regression analysis revealed that waist-to-height ratio had a significant association with HbA1c level (P=0.02), but age, sex, and nutritional status did not.Conclusion Waist-to-height ratio is correlated with HbA1c levels in overweight and obese adolescents.

Published: May 2017

This study assesses the geotechnical characteristics of lateritic soil and sawdust ash lime (SDAL) mixtures. Preliminary tests were carried out on the natural soil sample for identification and classification purposes. The sawdust was mixed with lime for stabilization in the ratio 2:1. This mixture was thereafter added to the lateritic soil in varying proportions of 2, 4, 6, 8 and 10% by weight of soil. Addition of SDAL increased values of Optimum Moisture Content (OMC) from 17.0% at 0% SDAL to 26.5% at 10% SDAL by weight of soil, also, values of Maximum Dry Density (MDD) decreased from 2040 kg/m3 at 0% SDAL to 1415 kg/m3 at 10% SDAL. Values of Unconfined Compressive Strength (UCS) increased from 38.58 kN/m2 at 0% SDAL to highest value of 129.63 kN/m2 at 6% SDAL. The values of liquid limits and plasticity index of the soil were effectively reduced with the addition of the SDAL, from 54.0% at 0% SDAL to 49.0% at 10% SDAL and from 13.7% at 0% SDAL to 12.5% at 10% SDAL respectively. It was therefore concluded that the sawdust ash lime (SDAL) mixture can serve as a cheap soil stabilizing agent for poor lateritic soil.
ANALYSIS OF NEIGHBOURING NOISE DISTURBANCE IN RECEIVING ROOM
Authors: Hejl Jaroslav
Published: May 2017

This paper is focused on analysis of neighboring noise as a disturbance agent. This problematics is closely connected with psychoacoustics or more generally with psychology. Therefore, methodology of research is based primarily on listening tests and questionnaires. The main research question lies in evaluation of difference of low/medium/high pitch noise on acoustic comfort of users. For purpose of this a method of auralization was introduced. The model was created by ODEON software and source noises were virtually reproduced through different partition walls. The virtual records in receiving room were accordingly replayed within listening tests. Results have shown that it is not easy to define one exact formula and answers depend on exact sounds and even there is not agreement through all of respondents. It should be mentioned that amount of respondents is too small for any definite statements. However, there is non-obvious and unexpected inclination to evaluated multi-layered light-weight structures as subjectively worse than adequately insulating concrete wall – at least from results obtained in this test. The possible explanation is an unnatural frequency spectrum of resulting sounds which are perceived as more disturbing despite they have lower sound pressure levels then in case of structure from reinforced concrete.
Resorting to Internet: A look at university students’ problematic Internet use through meaning in life, self-efficacy and self-esteem
Authors: Aydın Betül
Published: May 2017

Internet can be used in a maladaptive way to escape from or compensate perceived inadequacies or the problems experiencing in daily life. In relation to this, in this study the relationship of meaning in life, self-efficacy and self-esteem to problematic Internet use was examined. Furthermore, the role of meaning in life, self-efficacy and self-esteem in predicting problematic Internet use was investigated. The study was carried out 410 university students (280 females and 130 males) attending the different grades of various departments in a school of education in Rize, Turkey. In the study, Sociodemographic Data Form, Problematic Internet Use Scale, Meaning in Life Questionnaire, General Self-Efficacy Scale and Rosenberg Self-Esteem Scale were used as data collection instruments. The data were analyzed through SPSS 15.0 version and descriptive statistics, Pearson product-moment correlation coefficient and multiple linear regression analysis were utilized in the analysis. Results showed that presence of meaning in life (r=-.26, p<.01), self-efficacy (r=-.36, p<.01) and self-esteem (r=-.29, p<.01) are negatively and significantly correlated to problematic Internet use, on the contrary, search for meaning’s relationship was found in a positive way (r=.21, p<.01). Besides, presence of meaning in life, search for meaning in life and self-efficacy emerged as significant predictors of problematic Internet use. By discussing these results in line with the relevant literature, directions were given for further studies.
Effects of Traditional Advertising and Social Messages on Brand-Building Metrics and Customer Acquisition

Published: May 2017

This study examines the relative effectiveness of traditional advertising, impressions generated through firm-to-consumer (F2C) messages on Facebook, and the volume and valence of consumer-to-consumer (C2C) messages on Twitter and web forums for brand-building and customer acquisition efforts. The authors apply vector autoregressive modeling to a unique data set from a European telecom firm. This modeling approach allows them to consider the interrelations among traditional advertising, F2C impressions, and volume and valence of C2C social messages. The results show that traditional advertising is most effective for both brand building and customer acquisition. Impressions generated through F2C social messages complement traditional advertising efforts. Thus, thoroughly orchestrating traditional advertising and a firm's social media activities may improve a firm's performance with respect to building the brand and encouraging customer acquisition. Moreover, firms can stimulate the volume and valence of C2C messages through traditional advertising that in turn influences brand building and acquisition. These findings can help managers leverage the different types of messages more adequately.

Increasing evidence suggest that consumption of high-fat diet (HFD) can impact the maturation of brain circuits, such as during adolescence, which could account for behavioral alterations associated with obesity. In the present study, we used behavioral sensitization to amphetamine to investigate the effect of periadolescent HFD exposure (pHFD) in rats on the functionality of the dopamine (DA) system, a central actor in food reward processing. pHFD does not affect responding to an acute injection, however, a single exposure to amphetamine is sufficient to induce locomotor sensitization in pHFD rats. This is paralleled by rapid neurobiological adaptations within the DA system. In pHFD-exposed animals, a single amphetamine exposure induces an increase in bursting activity of DA cells in the ventral tegmental area (VTA) as well as higher DA release and greater expression of (tyrosine hydroxylase, TH) in the nucleus accumbens (NAc). Post-synaptically, pHFD animals display an increase in NAc D2 receptors and c-Fos expression after amphetamine injection. These findings highlight the vulnerability of DA system to the consumption of HFD during adolescence that may support deficits in reward-related processes observed in obesity.

The protein MSTO1 has been localized to mitochondria and linked to mitochondrial morphology, but its specific role has remained unclear. Lactate stress test and myopathological results suggest mitochondrial dysfunction. In patient fibroblasts, MSTO1 mRNA and protein abundance are decreased, mitochondria display fragmentation, aggregation, and decreased network continuity and fusion activity. Short‐term silencing of MSTO1 in HeLa cells reproduced the impairment of mitochondrial morphology and dynamics observed in the fibroblasts without damaging bioenergetics. At variance with a previous report, we find MSTO1 to be localized in the cytoplasmic area with limited colocalization with mitochondria. MSTO1 interacts with the fusion machinery as a soluble factor at the cytoplasm‐mitochondrial outer membrane interface. After plasma membrane permeabilization, MSTO1 is released from the cells. MSTO1 likely has a physiologically relevant role in mitochondrial morphogenesis by supporting mitochondrial fusion.§

Published: May 2017

BACKGROUND AND OBJECTIVE:

Survival of extremely preterm (EP; <28 weeks’ gestation) infants has increased over the last 2 decades. Equivalent reductions in developmental morbidity in early childhood have not been consistently reported. The aim of this study was to determine trends in neurodevelopmental outcomes at 8 years of age of children born EP (22–27 completed weeks’ gestation) over the past 2 decades.

METHODS:

Population-based cohorts of all EP survivors born in the state of Victoria, Australia in 1991–1992, 1997, and 2005 were recruited at birth. At 8 years of age, general intelligence (IQ), academic achievement, and neurosensory status were assessed. Major neurosensory disability was defined as any of moderate or severe cerebral palsy, IQ <−2 SD relative to term controls, blindness, or deafness.

RESULTS:

Rates of major neurosensory disability were similar in all eras (1991–1992, 18%; 1997, 15%; 2005, 18%), as were rates of IQ <−2 SD, cerebral palsy, blindness, and deafness. Mean z scores for IQ were similar across eras, but there was some evidence that scores for academic achievement were lower in 2005 than in 1997, and the odds of having academic problems were higher in 2005 than in both earlier eras. These outcomes were not explained by differences in known perinatal care or sociodemographic variables between eras.

CONCLUSIONS:

Contrary to expectations, rates of major neurosensory disability have not improved, and academic performance is poorer at early school age in 2005 than in earlier eras for EP children born in the state of Victoria, Australia.

*** Profile of elderly admitted to a physical therapy center as a function of seasonality ***AIMS: To analyze the profile and the prevalence of diseases in elderly patients admitted to a physical therapy center in a medium-sized Brazilian city located in a subtropical zone in two different seasons of the year.METHODS: A cross-sectional study assessed the medical records of patients treated during summer and winter months in 2011. Medical records of male and female elderly patients (aged over 60 years) were included, and those without information on present medical diagnosis were excluded. Age and sex and both current and previous diagnostic records were analyzed. The chi-square test was used for the comparative analysis of the profile of the elderly patients for both seasons.RESULTS: Seventy-one medical records were analyzed. The mean age was 69.2±8.1 years and 48 (70.4%) patients were female. There was a higher prevalence of trauma-orthopedic diseases (60.6%). The greatest number of admissions was in winter (62.0%). At the time of referral, there were 17 cases (63.0%) of trauma-orthopaedic diseases in summer and 26 (59.1%) in winter; 3 cases (11.1%) of rheumatologic diseases in summer and 10 (22.7%) in winter; 5 cases (18.5%) of neurologic disorders in summer and 4 (9.1%) in winter; and 2 cases (7.4%) of postoperative complications in summer and 4 (9.1%) in winter (p=0.64).CONCLUSIONS: There was a greater demand for referrals of elderly patients to the physical therapy center in winter than in summer, with a predominance of female patients in both seasons. The most prevalent causes of referral were related to trauma-orthopaedic diseases, but there was no significant difference in the frequency of diagnoses according to season. Knowledge about the profile of the elderly admitted to physical therapy centers is important for targeting actions at this age group, conducting information, prevention, and health promotion campaigns.

*** Oxidative stress in patients with type 2 diabetes mellitus treated with metformin ***AIMS: To evaluate oxidative stress parameters in patients with type 2 diabetes mellitus treated with metformin, relating these values to its side effects, plasma levels, glycemic control, diabetic complications, lipid profile, and the influence of pharmacotherapeutic follow-up.METHODS: Patients with type 2 diabetes mellitus, on metformin and in pharmacotherapeutic follow-up for four months, were evaluated. The pharmacotherapeutic follow-up consisted in providing information and answering patients’ questions about medication and disease. In addition, administration times, dosages, and presence or absence of side effects related to the use of metformin were verified. Glycemic and lipid profile, oxidative stress (superoxide dismutase and malondialdehyde) and plasma metformin were evaluated. Pearson’s correlation and Spearman’s correlation were performed to evaluate the relationship between the variables at the beginning of the study. The independent t-test and Mann-Whitney U test were used to assess the difference between the groups with and without diabetic complications. The range of values between the beginning and  end of the study was evaluated using Student’s t-test or Wilcoxon U test. The significance level was set at 5%.RESULTS: The initial sample consisted of 49 patients aged 59±9 years with a body mass index of 29.8±5.1 kg/m2, who have had diabetes for a median time of 36 months (interquartile range of 1-240) and have been on metformin for a median time of 36 months (interquartile range of 1-180). Twenty-five patients left the study between the second and fourth meetings. Malondialdehyde levels differed between before and after pharmacotherapeutic follow-up, being positively correlated with blood glucose, glycohemoglobin, and triglyceride level, and negatively correlated with metformin and superoxide dismutase. Blood glucose, glycohemoglobin, and malondialdehyde levels increased, whereas metformin levels decreased in the group with diabetic complications, and there was a correlation between malondialdehyde and the number of diabetic complications per patient.CONCLUSIONS: In this sample of patients with type 2 diabetes mellitus treated with metformin, oxidative stress was more pronounced in those with poor glycemic control and diabetic complications.

Endophthalmitis is one of the most important complications after cataract surgery and in case event can cause many symptoms, such as severe decrease in eyesight and/or even the loss of vision. Employing methods to reduce this problem is very important. The aim of this study was to evaluate the effect of intracameral cefuroxime after cataract surgery on corneal endothelial cell counts and its morphology.

Methods

In this study, 32 eyes of 30 patients underwent endothelial cell count and morphology assessment by ConfoScan III device before and 1 month after cataract surgery. All patients undertaken cataract surgery by one surgeon and by one method. Intracameral cefuroxime (1 mg/0.1 ml) was used as prophylaxis of postoperative endophthalmitis at the end of operation.

Results

In this study, the rate of corneal endothelial cell loss 1 month after cataract surgery was 8.4%, and the rate of endothelial cells polymegathism before and after cataract surgery did not differ statistically. During the follow-up period, there were no cases of endophthalmitis or other complications.

Conclusion

With regard to the importance of the intracameral cefuroxime in a reduction in the rate of endophthalmitis after cataract surgery and that harmful effects on the endothelial cells were not seen, this method can be considered as a suitable method for endophthalmitis prophylaxis.

Ikan nila (Oreochromis niloticus) dan ikan komet (Carassius auratus) adalah komoditas ikan konsumsi dan ikan hias air tawar yang paling banyak dibudidayakan masyarakat Indonesia. Namun keberadaan bahan pencemar seperti nonilphenol dapat mengancam produktivitas kegiatan budidaya ikan tersebut karena dapat menyebabkan gangguan perkembangan bahkan kematian khususnya pada tahap awal perkembangan ikan (early development stage). Penelitian ini bertujuan untuk mengetahui tingkat toksisitas akut median lethal concentration (LC50) nonilphenol pada larva ikan nila dan ikan komet. Penelitian dilakukan di laboratorium Balai Penelitian dan Pengembangan Budidaya Ikan Hias (BPPBIH) Depok. Penelitian terdiri atas uji mencari nilai kisaran (range finding test/RFT) dan dilanjutkan dengan uji akut. Level konsentrasi nonilphenol diatur berdasarkan deret logaritmik di mana untuk RFT menggunakan konsentrasi 0,01; 0,10; dan 1,00 mg/L; sedangkan level konsentrasi nonilphenol untuk uji akut ditentukan dari hasil RFT. Hasil analisis probit menujukkan nilai LC50 nonilphenol pada jam ke-96 pada larva ikan nila dan ikan komet berturut-turut berada pada konsentrasi nonilphenol 0,33 dan 0.10 mg/L. Sementara kematian 100% (LC100) larva ikan nila dan ikan komet pada jam ke-96 masing-masing berada pada konsentrasi 0,61 dan 0,50 mg/L. Merujuk pada kriteria toksisitas bahan dari Komisi Pestisida Departemen Pertanian, maka hasil penelitian ini menunjukkan bahwa nonilphenol tergolong dalam bahan berbahaya dengan daya racun yang sangat tinggi.Nile tilapia (Oreochromis niloticus) and comet goldfish (Carassius auratus) are the major fresh water fish commodities in Indonesia used for both consumption and ornamental fish. However, production of the fish threatened by the presence of nonylphenol which can interfere with early development stage. Research objectives were to evaluate acute toxicity of nonylphenol to larval of nile tilapia and comet goldfish and to compare median lethal concentration (LC50). Research was carried out in the RDIOF, Depok. Experiments consisted of range finding test/RFT and accute test. Nonylphenol concentrations of RFT were 0.01, 0.10, and 1.00 mg/L. The results showed that LC50-96 hours of tilapia and comet were 0.33 and 0.10 mg/L respectivelly. Total mortality (LC100-96 hours) for tilapia and comet were 0.61 and 0.50 mg/L respectivelly. These results of nonylphenol concentrations, according to toxic level criteria by The Department of Agriculture’s Pesticide Commission, is categorized as dangerous goods with very high level of toxicity.

Uczynki miłosierdzia względem ciała i duszy. Historia i praktyka
Authors: Gryz Krzysztof
Published: May 2017

Wspomaganie biednych i potrzebujących uczynił Kościół ważnym elementem swojego posłannictwa, jako odpowiedź na wyraźny nakaz realizacji przykazania miłości bliźniego dany przez Chrystusa. Obowiązek okazywania czynnej miłości bliźniemu został wyrażony w katechizmowej formule uczynków miłosierdzia co do ciała i co do duszy. Artykuł analizuje zarówno genezę powstania tej formuły, jak również jej historyczną interpretację na przestrzeni wieków.Uczynki miłosierdzia co do ciała zostały wyraźnie sformułowane przez samego Chrystusa w kontekście nauki o sądzie ostatecznym, zapisanej w Ewangelii św. Mateusza 25, 31–40, natomiast uczynki co do duszy znajdują swoje biblijne uzasadnienie w różnych miejscach Ewangelii. W III wieku Orygenes w duchu egzegezy alegorycznej interpretował uczynki miłosierdzia wymienione w Ewangelii Mateusza także jako wezwanie do pomocy w duchowych potrzebach człowieka, a za nim na Zachodzie czynił tak św. Augustyn. W ten sposób stopniowo rodziła się lista siedmiu uczynków co do duszy.Klasyczną interpretację moralną uczynków miłosierdzia podał św. Tomasz z Akwinu, ustalając, w jakich warunkach są one ścisłą powinnością moralną. W późniejszym okresie w praktykowaniu miłosierdzia podkreślano takie elementy jak: osobiste doświadczenie Bożego miłosierdzia jako wezwanie do pomocy innym (św. Faustyna), dowartościowanie człowieka w jego godności (św. Jan Paweł II) oraz w ostatnim czasie troska o ludzi wykluczonych, czyli pozbawionych możliwości własnego rozwoju (papież Franciszek).
Formuły trynitarne we wschodnich i zachodnich modlitwach eucharystycznych
Authors: Królikowski Janusz
Published: May 2017

Sakramenty chrztu i Eucharystii stanowią centrum liturgii Kościoła, gdyż są uroczystą celebracją tajemnicy wiary oraz wskazują na te treści, które stanowią kluczowy punkt odniesienia dla życia wszystkich wierzących. Fakt ten widać przede wszystkim w tym, że od samego początku istnienia Kościoła obrzędy chrztu i Eucharystii stanowią pierwsze i najważniejsze świadectwo wiary w Trójcę Świętą oraz są wyznaniem tej wiary. Ta ogólna obserwacja wyznacza perspektywę niniejszego studium, w którym pokazujemy, w jaki sposób w liturgii następowała pewna ewolucja wiary w Trójcę Świętą i jak doszło do utrwalenia tej wiary w obecnej liturgii. W niniejszym studium dokonujemy więc przeglądu formuł trynitarnych, które można znaleźć w liturgiach wschodnich i zachodnich, aby pokazać, w jaki sposób wyrażają się w nich treści trynitarne. W odniesieniu do liturgii zachodnich zwracamy szczególną uwagę na liturgię rzymską i liturgię gallikańską, które wyraźnie oddziaływały na siebie w dziejach, a obecna liturgia rzymska jest rezultatem tego oddziaływania. Pośrednim efektem rozwoju formuł trynitarnych oraz pobożności o charakterze trynitarnym jest także liturgiczne święto Trójcy Przenajświętszej, które mimo pewnych początkowych trudności zajęło na trwałe miejsce w liturgii Kościoła. Przeprowadzone analizy pokazują przede wszystkim, że liturgia Kościoła jest ważnym świadectwem wiary trynitarnej oraz szkołą jej przeżywania w kluczu soteriologicznym. Lepsze odczytanie propozycji liturgicznej mogłoby przyczynić się do ożywienia wiary trynitarnej i wydobycia jej znaczenia egzystencjalnego.
Bóg i mass media w orędziach papieża Benedykta XVI na Światowe Dni Środków Społecznego Przekazu
Authors: Misztal Wojciech
Published: May 2017

Na ważne i interesujące nauczanie papieża Benedykta XVI składają się m.in. orędzia na Światowy Dzień Środków Społecznego Przekazu. Orędzia te pozwalają zapoznać się z właściwym Benedyktowi XVI rozumieniem odniesień między Bogiem i nowoczesnymi środkami przekazu myśli, komunikacji. To papieskie rozumienie zarazem stanowi wskazanie, jak do mediów podchodzić, jak z nich korzystać obecnie i w przyszłości. W opracowaniu uwzględniono papieską prezentację związków między Bogiem i współczesną cywilizacją, obraz Boga w omawianych orędziach oraz rozumienie mediów jako wielorako pozytywnie z Nim związanych.
Przepowiadanie do ludzi w podeszłym wieku
Authors: Sławiński Henryk
Published: May 2017

Wiele uwagi poświęca się w homiletyce i przepowiadaniu dzieciom. Nieproporcjonalnie mało uwagi poświęca się natomiast osobom starszym. Niniejsze opracowanie uzupełnia ten brak. Najpierw podjęta jest próba opisu, kim są ludzie starsi, następnie omówione jest ich miejsce w życiu parafialnym. W dalszej kolejności podjęta jest analiza ludzi starszych jako audytorium kościelnego przepowiadania. W konsekwencji omówione są najważniejsze kwestie egzystencjalne, które dotyczą tej grupy słuchaczy, sposób i okoliczności przepowiadania do nich oraz postawa głosiciela wobec takiego audytorium.
Argumenty na nieistnienie Boga wobec teo-ontologii trynitarnej
Authors: Strumiłowski Jan
Published: May 2017

Analiza poszczególnych argumentów na nieistnienie Boga pokazuje, że w różnym stopniu dotykają one kwestii metafizycznych. Niektóre wprost zakładają odmienny model metafizyczny aniżeli ten przyjmowany przez teistów. Inne wydają się nie dotykać wprost kwestii metafizycznych, a poruszają się w innej przestrzeni – na przykład egzystencjalnej. Jednakże i te w pewien sposób są zapośredniczone metafizyczne, przez co zakładają konkretny obraz Boga i konkretny model ontologiczny, który również często różni się od modelu teistycznego.Niemniej nawet w przypadku, kiedy przyjęta metafizyka i model Boga są zgodne z myśleniem teistycznym, tzn. kiedy argumenty są wymierzone w kierunku filozoficznego Absolutu, nie oznacza to, że owe argumenty posiadają swoje znaczenie także względem Boga Trójjedynego. Dogmat o Trójcy dotyczy istoty Boga, która determinuje w kontekście stwórczym konkretny model metafizyczny. Niniejszy artykuł wobec takiej zależności poddaje analizie argumenty ateistyczne w świetle teo-ontologii, pytając, czy mieszczą się one w jej modelu.
Negacja w języku teologii
Authors: Olszewski Adam
Published: May 2017

W pierwszej części artykułu prezentuję krótki przegląd tego, czym jest negacja z punktu widzenia filozofii i logiki. W drugiej części przedstawiam przykłady pięciu rodzajów negacji, które są używane w języku teologii katolickiej. Co zaskakujące, jest to wynik skomplikowanej struktury teologii.
Metody odkrycia prawdy procesowej przez sędziego w kanonicznym procesie małżeńskim
Authors: Brzemia-Bonarek Aleksandra
Published: May 2017

Niniejszy artykuł w swoich założeniach: „najpierw rzeczy pierwsze”,  ma na celu zwięzłe przypomnienie o nadrzędnej wartości kanonicznego procesu małżeńskiego jaką jest prawda obiektywna, do której, poprzez różne metody poznania intelektualnego musi dojść sędzia kościelny badający sprawę o stwierdzenie nieważności małżeństwa. Autorka wskazuje i krótko opisuje kryteria pozwalające sędziemu poznanie prawdy w procesie takie jak: pewność moralna, swobodna ocena dowodów, obiektywizm. Zwraca również uwagę na charakterystykę osoby sędziego jako badacza sprawiedliwości. W publikacji przywołane zostają cechy i postawy, które wspomagają sędziego w przepowiadaniu prawdy, ale które mogą w pewnych okolicznościach osłabić też jego obiektywizm. Tenor myśli przewijającej się w pracy jest następujący: żadne racje pastoralne nie osłabiają nakazu osiągnięcia przez sędziego prawdy obiektywnej. Ta bowiem zawiera się w fundamentalnej kodeksowej zasadzie salus animarum.

The nucleophilic substitution of the nitro group of 4-alkyl-6-nitro-4,7-dihydro-1,2,4-triazolo[5,1-c][1,2,4]triazine-7-ones on the example of interactionwith morpholine was studied. It is established that under the action of excess cycloalkylimine at room temperature the unusual easy disclosure of triazine cycle with the formation of sterically hindered hydrazones occurs which are the key intermediates for further transformations. The carrying of reaction at elevated temperatures leads to the formation of products of substitution of the nitro group with the amine and also with morpholyl hydrazones which are the products of hydrolysis of amides of hydrazones and subsequent decarboxylation. Thus, the nucleophilic substitution of the nitro group in the described triazolotriazines flows through the ANRORC mechanism.
Development of a new calcium sulfoaluminate (synthetic ye'elimite) blended PII 52.5 cement
Authors: Zhang Yu , Zhang Zuhua , Shi Chaoqi , Wang Hao , Shen Xiaodong
Published: May 2017

The aim of this paper is to examine the effect of a blending dose of calcium sulfoaluminate (synthetic ye'elimite, C4A3$) and gypsum on the hydration and hardening properties of a new ye'elimite (C4A3$) blended PII 52.5 cement. By using X-ray diffractometry, mercury intrusion porosimetry, thermogravimetry and scanning electron microscopy, it was revealed that the hydration of tricalcium silicate (C3S) is significantly retarded by the lack of gypsum; the renewed hydration of tricalcium aluminate (C3A) was retarded in cement pastes containing a high amount of C4A3$. The dosage of C4A3$ and the ratio of gypsum/C4A3$ both have a notable influence on the hydration heat, hydration products and the compressive strength and linear expansion. The cement paste containing 3% C4A3$ at gypsum/C4A3$ ratio of 2 exhibited the best performance, in terms of both high early and long-term compressive strength and acceptable linear expansion (0·04% on 300 d); the cement can therefore be adopted in industrial structures.
Strength–dilatancy relation of sand containing non-plastic fines
Authors: Xiao Y. , Xiang J. , Liu H. , Ma Q.
Published: May 2017

Bolton's stress–dilatancy equation is mainly used for clean sands. It needs to be investigated whether this equation could be used for sand with non-plastic fines or not. A series of drained triaxial compress tests were conducted for the sand with non-plastic fines. It was observed from these tests that the peak-state and critical-state friction angles increased with increasing the fines content. The peak-state friction angle and maximum dilatancy angle increased with decreasing the confining pressure. It was also found that the relationship between the excess friction angle (i.e. the difference between the peak-state and critical-state friction angles) and maximum dilatancy angle was unchanged with the non-plastic fines content. This has illustrated that the Bolton's stress–dilatancy equation proposed for clean sands could still be applied to sands with non-plastic fines.
A Study on the Effects of Authentic Leadership on Job Stress, Job Satisfaction, and the Commitment to Change among Employees in Super-Deluxe Hotels
Authors:   The Tourism Sciences Society Of Korea, Byun Jae-Woo , Ko Jae-Youn
Published: May 2017

This study provides a theoretical framework for understanding the effects of authentic leadership (AL) of supervisors on hotel employee job stress (JS), job satisfaction(JSa), and commitment to change(CC). Pertinent hypotheses were tested using empirical data collected through self-administered questionnaires distributed to employees of super-deluxe hotels located in the cities of Seoul, Incheon, and Busan, as well as the provinces of Gyeonggi and Jeju between November 25th, 2015, to January 14th, 2016. Out of the 522 questionnaires distributed, 511 were collected. After removing incomplete responses, 471 valid samples were used in the final analysis. Results confirm that the AL of supervisors has a significant effect on job stress(JS) and job satisfaction(JSa). Furthermore, JS has a significant impact on JSa, JS and JSa simultaneously and all these factors influence the commitment to change (CC). It is suggested that future studies focus on developing concepts for quantitative measurement of AL, JS, JSa and CC.
Effects of Abusive Supervision on Organizational Silence Throughout the Hotel Industry
Authors:   The Tourism Sciences Society Of Korea, Paek Su-Jean , Kang Jae-Wan
Published: May 2017

The purpose of this study was to analyze the moderating effect of rank on the relationship between a supervisor's abusive supervision and the subsequent organizational silence of Super-Deluxe hotel employees. 500 responses were taken and analyzed from Super-Deluxe hotel employees while applying a structure equation model analysis and a moderating effect analysis yielded the following results: First, a supervisor's abusive supervision had a significant influence on four sub-factors which were organizational silence, acquiescent silence, defensive silence and prosocial silence. Second, employee rank moderated the relationship between a supervisor's abusive supervision and subsequent organizational silence thus supporting the research hypothesis. Results of the study confirm that a supervisor's abusive supervision increases the organizational silence of employees throughout the hotels studied. It is suggested that hotels should eliminate abusive supervision and better manage human resources according to department and rank.
Mixed and Mixing Systems Worldwide: A Preface
Authors: Donlan Seán Patrick
Published: May 2017

This issue of the Potchefstroom Electronic Law Journal (South Africa) sees the publication of a selection of articles derived from the Third International Congress of the World Society of Mixed Jurisdiction Jurists (WSMJJ). That Congress was held at the Hebrew University of Jerusalem, Israel in the summer of 2011. It reflected a thriving Society consolidating its core scholarship on classical mixed jurisdictions (Israel, Louisiana, the Philippines, Puerto Rico, Quebec, Scotland, and South Africa) while reaching to new horizons (including Cyprus, Hong Kong and Macau, Malta, Nepal, etc). This publication reflects in microcosm the complexity of contemporary scholarship on mixed and plural legal systems. This complexity is, of course, well-understood by South African jurists whose system is derived both from the dominant European traditions as well as from African customary systems, including both those that make up part of the official law of the state as well as those non-state norms that continue to be important in the daily lives of many South Africans.
