Perubahan Budaya Organisasi dari Universitas Pembelajaran ke Universitas Penelitian di Universitas Lampung
Authors: Rosalia Feni
Published: July 2019

Universitas Lampung (Unila) adalah salah satu Perguruan Tinggi Negeri di Indonesia yang memiliki visi menjadi 10 (sepuluh) perguruan tinggi terbaik di Indonesia pada tahun 2025. Dari Universitas Pembelajaran menuju Universitas Penelitian Unila dituntut memiliki budaya organisasi yang jelas. Sebagai sebuah organisasi perguruan tinggi, dalam menjalankan aktivitas Unila tidak terlepas dari adanya perubahan budaya. Jika mengarah pada budaya meneliti, Unila dituntut untuk menyediakan keunggulan kompetitif yang strategis terkait budaya meneliti tersebut. Unila harus memperbanyak penelitian atau publikasi ilmiah untuk menuju Universitas Penelitian. Tujuan yang ingin di capai dalam penelitian ini adalah mengetahui budaya organisasi di Unila serta mengetahui proses perubahan budaya, dari Universitas Pembelajaran kepada Universitas Penelitian. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif karena penelitian ini bertujuan untuk menjelaskan berbagai kondisi, situasi, atau variabel yang timbul dari objek penelitian. Populasi dan sampel dalam penelitian ini adalah Tenaga Pendidik Universitas Lampung. Teknik pengumpulan data yang digunakan adalah kuisioner. Teknik analisis data menggunakan analisa univariat dan bivariat yang di peroleh dari hasil kuisioner. Hasil penelitian menunjukkan bahwa budaya organisasi Universitas Lampung sudah mengarah pada perubahan budaya dari Universitas Pembelajaran ke Universitas Penelitian. Namun perubahan tersebut belum tercapai maksimal, karena budaya organisasi dalam hal kepemimpinan, kebijakan, sarana dan prasarana, serta pendanaan masih mengalami banyak kendala. Walaupun budaya meneliti tenaga pendidik meningkat namun tidak menyeluruh, karena hanya terbatas pada beberapa fakultas saja. Tim peneliti merekomendasikan pada perubahan budaya organisasi sebagai ujung tombak terciptanya maksimalisasi budaya meneliti di Universitas Lampung.
Encountering Evil: The Evil-god Challenge from Religious Experience
Authors: Lancaster-Thomas Asha
Published: July 2019

It is often thought that religious experiences provide support for the cumulative case for the existence of the God of classical monotheism. In this paper, I formulate an Evil-god challenge that invites classical monotheists to explain why, based on evidence from religious experience, the belief in an omnipotent, omniscient, omnibenevolent god (Good-god) is significantly more reasonable than the belief in an omnipotent, omniscient, evil god (Evil-god). I demonstrate that religious experiences substantiate the existence of Evil-god more so than they do the existence of Good-god, and, consequently, that the traditional argument from religious experience fails: it should not be included in the cumulative case for the existence of Good-god.
Electrolytic colouring of anodized aluminium on tin basis
Authors: Šopová Barbora , Zemanová Matilda
Published: July 2019

The aim of the study was to find parameters of electrolytic colouring on tin basis to form uniform black coatings on anodized aluminium. A two steps electrolytic process consisting of aluminium anodization in a sulphuric acid electrolyte and colouring in tin acidic electrolyte was used. Among parameters influencing the colouring process, AC colouring voltage, composition of the counter electrode and agitation of the colouring electrolyte were studied. Spectrocolorimetry was applied to analyse the quality of the colouring. Thickness of the coloured and sealed anodized specimens was also evaluated. Optimal parameters for uniform colouring of anodized specimens were found. Unfortunately, colouring electrolyte on tin basis is susceptible to oxidation which negatively influences the colouring.

Published: July 2019

The aim of the research was to prepare and characterize hydrotalcite synthesized under different preparation conditions. The most common hydrotalcite preparation is the co-precipiaton method. The preparation process strongly influences the catalytic properties of hydrotalcite; therefore, optimal conditions have to be determined. During the study, seven samples of the catalyst were prepared in the pH range from 8 to 12 and the synthesis temperature range from 25 to 55 °C. Based on several catalyst properties, optimal synthesis pH 10 was found. Ideal temperature of the preparation was determined to be 35 °C, but the temperature does not have a significant effect on the catalyst properties.

Authors: Urminská Barbora , Derco Ján , Zakhar Ronald , Korpicsová Adriana
Published: July 2019

Natural or synthetic zeolites have unique physical, chemical and structural properties that predetermine their use in many processes, including wastewater treatment. This study presents the results of our preliminary research in the field of nitrogen and phosphorus removal using adsorption and adsorptive ozonation with natural and modified zeolites. Iron-modified zeolite was the most efficient for the removal of ammonium nitrogen by adsorption. Phosphorus removal efficiency using adsorption was relatively low and natural zeolite was not suitable for the phosphorus removal at all. Ozone had no significant impact on the removal efficiency. Regeneration of loaded zeolites with ozone has also been studied. This method was partly efficient but it needs be further examined.
Budget transparency innovation in the Czech local government
Authors: Sedmihradská Lucie
Published: July 2019

Budget transparency innovations bring new extent and forms of transparency. The aim of the article is to explore the diffusion of budget explorers, that is, a budget transparency innovation extremely popular in the Czech Republic, and to evaluate their impact on voluntary budget information disclosed.

Careful mapping of the diffusion using a survey of budget explores in 72 former Czech district towns and media analysis shows that the key success factor was its convenience for politicians, as it is attractive, easy to implement and up-to-date demonstration of their transparency. Budget explorers are nowadays a standard extension to accounting software, and their usage is evaluated in several government transparency competitions.

The major benefit of the budget explorers is that they made for the first time publicly available detailed public financial information, changed the standard of best practice and drew some public attention. At the same time, they, unfortunately, narrowed the scope of the budget transparency debate by omitting the importance of the draft budget and introduction of performance measurement.
Local Political Business Cycles and Administration Spending in Polish Local Governments
Authors: Olejnik Łukasz Wiktor
Published: July 2019

Subject and purpose of work: The purpose of this article is to verify the hypothesis of the occurrence of political business cycles at the self-governmental level in Poland.

Materials and methods: The article presents a quantitative analysis of expenditures on remuneration in the administration of Polish self-governments at the county (district) level (in the period 2007–2018) and at province (regional) level (in the period 1999–2018) with the use of Arellano-Bond and LSDVC estimators.

Results: The panel data analysis makes it possible to conclude that in Polish self-governments cyclical fluctuations of expenditure on remuneration can be observed. The increase in salaries depends on the power of the ruling coalition as well as unemployment and the output gap in a region. In the case of provinces and counties, also the increase of investment expenditures significantly affects the increase of salaries.

Conclusions: The results of the estimation of models clearly point to the presence of cyclical distortions in remuneration in public administration, which are caused by the upcoming elections.
Nectar and pollen production in ornamental cultivars of Prunus serrulata (Rosaceae)
Authors: Strzałkowska-Abramek Monika
Published: July 2019

Planting ornamental species can help to create pollinator-friendly habitats. In the present study the flowering phenology and floral reward (nectar and pollen) in two cultivars of Prunus serrulata (‘Kanzan’ and ‘Amanogawa’) were evaluated in 2014-2015 in the city of Lublin (south-east Poland). On average, the onset of flowering of P. serrulata occurred in the first ten days of April (‘Kanzan’) or at the end of April (‘Amanogawa’), and lasted 8-17 days. In each year of the study, P. serrulata ‘Kanzan’ started flowering 11-18 days earlier than P. serrulata ‘Amanogawa’. The double flowers of P. serrulata ‘Kanzan’ offered only tiny amounts of nectar and pollen. The total mass of sugars was 0.59 mg per flower and that of pollen 0.08 mg per flower. The semi-double flowers of P. serrulata ‘Amanogawa’ produced 4.5 mg of sugars per flower and 0.17 mg of pollen per flower. The frequency of pollinator visits to flowers was low in P. serrulata ‘Amanogawa’ and very low in P. serrulata ‘Kanzan’. Therefore, if pollinator-friendly arrangements are made in urban areas, these cultivars should not be planted.

Published: July 2019

The aim of our work was to assess the direction of change taking place in the forests of the regional directorates of State Forests (rdSF) based on measurable indicators used to assess sustainable development. Based on a synthetic index (Z), changes in the years 1993−2013 were evaluated for individual directorates. We identified the regions with the highest and lowest rates of change in terms of sustainable development dynamics. The analysis was performed using spatiotemporal variables and the main criterion for selecting the diagnostic variables was their availability and comparability over the analysed period. The rdSF variation was assessed with the synthetic index (Z), using the method of zero unitarisation. In 1993−2013, favourable changes over time were indeed recorded, reflecting the progress in implementing practices supporting sustainable development in forestry. However, large differences exist between the regional managements in this respect. For the analysed period, the most favourable conditions from the perspective of sustainable forest management were maintained in rdSF Kraków, rdSF Białystok and rdSF Toruń, while the least desirable conditions were found in rdSF Zielona Góra, rdSF Piła and rdSF Warsaw. The greatest rates of beneficial change, on the other hand, were found in rdSF Szczecin, rdSF Kraków and rdSF Wrocław. In turn, the lowest rates of change of the synthetic index (Z) were observed in the directorates of Katowice, Piła and Łódź. In summary, measurable indicators of sustainable development are a good instrument for measuring the pace of change in sustainable forestry. They are an effective tool for assessing and reporting progress over time and should also be used when planning and implementing development strategies.
Spirocercosis in Dogs in Israel
Authors: Geva N. , Štrkolcová G.
Published: July 2019

Spirocerca lupi is a nematode causing spirocercosis disease that affects mostly carnivores and especially canidae. The life cycle of S. lupi includes a coprophagous beetle as an obligatory intermediate host and a variety of facultative paratenic hosts. In Israel, spirocercosis is considered to be a serious condition with a variety of clinical signs comprising a great risk to canine populations. The diagnosis at an early infective stage is unreliable and the vast majority of infected dogs are diagnosed only when the disease has advanced. In advanced stages of the disease, treatment is difficult and there is a high risk for complications. A study was carried out to compare the prevalence of S. lupi in the central region of Israel with a previous investigation and by that consequently try to estimate the efficacy of preventative treatment used nowadays in Israel. The study was done by the use of two different methods: looking for the infective larvae (L3) in the main intermediate host in Israel, Ontophagus sellatus, and searching for the eggs of S. lupi by performing flotation methods on faecal samples. Beetles and faecal samples were collected from four different locations in the winter and summer of 2017, 2018, and 2019. According to the literature review and collection of data from case studies, the prevalence of spirocercosis is increasing in Israel, despite the negative results from the dissections of beetles and faecal samples.

Authors: Ničová K. , Schwarzbacherová V. , Galdíková M. , Holečková B.
Published: July 2019

Acetamiprid, that is known as the commercial formulation Mospilan® 20SP is the part of the neonicotinoid insecticide group and is widely used against various pests. In our study we assessed the potential clastogenic effects of Mospilan® in human peripheral blood lymphocytes in vitro using a chromosome aberration test. The lymphocytes were treated with acetamiprid in the concentration range of 5, 10, 25 and 50 µg.ml−1 for 24 and 48 h. After 24 h exposure, the insecticide induced statistically significant higher levels of chromosome aberrations from the concentration of 10 µg.ml−1 (P < 0.05 and P < 0.001) and a significant decrease in mitotic index (MI) at the concentrations of 25 and 50 µg.ml−1 (P < 0.05 and P < 0.01), respectively. After a 48 h exposure, we found a dose dependent increase in the percentage of chromosome aberrations at all concentrations (P < 0.05; P < 0.01 and P < 0.001) and a decrease in MI at concentrations of 25 and 50 µg.ml−1 (P < 0.05 and P < 0.01). Our results indicated that neonicotinoid insecticide formulations containing acetamiprid may have potential cytotoxic and genotoxic effects.

Published: July 2019

Different chemicals can have genotoxic effects on the body, as confirmed by chromosome damage detection. Using conventional cytogenetic analysis and fluorescence in situ hybridization, we tested the extent of chromosome damage caused by the acetamiprid-based insecticide Mospilan 20SP on bovine peripheral blood lymphocytes at concentrations of, 2.5, 5, 25 and 50 µg.ml−1 after a 24 h incubation period. During the experiment, the presence of unstable aberrations—chromosomal and chromatid breaks and gaps—were detected by conventional cyto-genetic analysis. With increasing insecticide concentrations, we observed a statistically significant increase in chromosome damage frequency after 24 hours of exposure. Fluorescence in situ hybridization was used to detect stable structural aberrations; whole-chromosome painting probes for bovine chromosomes 1 and 7 (BTA 1 and BTA 7) were used for this purpose. As a result of exposure to the insecticide, neither BTA 1/BTA 7 translocations nor other types of translocations were observed.

Authors: Strapáč I. , Bedlovičová Z. , Baranová M.
Published: July 2019

In this study we examined the dried fruiting bodies of Morchella esculenta, collected in the area of the coal and biomass based thermal power plant in Vojany from the nearby Bahoň marsh, in the Slovak Republic. The area is characterized by a high environmental burden, especially because of air pollutant emissions from the power plant operation. Twenty-three (23) chemical elements were found in the dried fruiting bodies after microwave-assisted sample preparation using an Inductively Coupled Plasma Mass Spectrophotometer ICP-MS AGILENT 7500c system. The mercury content was determined employing a special AMA 254 apparatus intended for the determination of Hg directly in dry powdered fruiting bodies without microwave digestion. The content of toxic elements expressed in mg.kg−1 DW (dry weight) were as follows: Hg 0.048—0.052 (RSD—Relative Standard Deviation = 4.80 %); Cd 4.543—6.169 (RSD = 3.35 %); Pb 0.261—0.291 (RSD = 2.67 %); As 0.455—0.469 (RSD = 5.79 %); Cr 1.585—1.616 (RSD = 2.33 %); and Ni 8.166—9.276 (RSD = 3.03 %). The contents of cadmium, nickel and mercury exceeded the hygiene limits, while the contents of arsenic and lead approached the hygiene limits. Due to the high levels of toxic elements, the fruiting bodies collected in the location are not suitable for culinary purposes. The mushroom Morchella esculenta acts as an accumulator of toxic elements from the environment in which it grows and can be considered as an indicator of environmental pollution.

Published: July 2019

Introduction: Osteoporosis is a chronic metabolic disease with multifactorial etiology. One of possible osteoporosis causes may be impairment of osteoclasts function which leads to increased bone resorption. This may be a result of many metabolic changes. It is believed that changes of folate-methionine metabolism in osteoporosis play an essential role in the etiology of this disease.

Objective: The aim of this study was to examine how polymorphisms of SLC19A1 and FOLR3 genes may play the key role in folate-methionine pathway and influence on the etiology of osteoporosis.

Results: The statistically overrepresentation of mutated GG genotype of FOLR3 (rs11235449) was observed in the control group compared to the osteopenia (34.9% in osteopenia vs. 37.8% in controls, p=0.025, OR=0.61). As to the SLC19A1 (rs3788200) polymorphism we have noted the statistically significant over-representation of wild-type GG genotype (35.8% vs. 26.2%, p=0.046, OR=1.57) and overrepresentation of wild-type G allele (56.9% vs. 50.2%, p=0.061, OR=1.31) in osteopenia group if compared to the controls.

Conclusions: In our study we shown the protective role of mutated GG genotype of FOLR3 (rs11235449) polymorphism to osteopenia progress and possible role of wild-type GG genotype and wild-type G allele of SLC19A1 (rs3788200) polymorphism in osteopenia development.

Published: July 2019

Industrial hemp (Cannabis sativa L.) attracts increasing interest of growers, in relation to both industrial and medical purposes. Construction is the most promising area of the economy for hemp, and specifically, the fast-growing production of insulation and bio-composite materials.

The most significant factors affecting the final yield of hemp seeds and biomass include: climatic factors, i.e. influence of weather conditions that determines the content of cannabinoids in plants; genetic predisposition of the variety used as well as agrotechnical factors. The article provides information on the botanical characteristics of fiber hemp, hemp cultivation area, Polish monoecious varieties of industrial hemp, hemp's agricultural requirements, including: the demand for macroelements (nitrogen, phosphorus, potassium, calcium); choice of soil, pioneer crop, and field preparation; sowing timing and density; harvest time; water conditions; heat and light requirements for hemp. The review article is focused mainly on the results of studies carried out at the Institute of Natural Fibres and Medicinal Plants, data of the Agency for Restructuring and Modernization of Agriculture (ARiMR), Research Centre for Cultivar Testing (COBORU), European Industrial Hemp Association (EIHA), published in 2008 - 2018.

Published: July 2019

The number of recreational athletes completing a Half-Ironman triathlon has increased exponentially in recent years. However, there is a lack of research on how to train for this kind of an event. The purpose of this study was thus to analyse triathletes’ changes in performance and body composition following a triathlon-specific training period. Fourteen male amateur triathletes completed a 7-week period of general training and a 13-week period of specific training for a Half-Ironman triathlon. Anthropometric measures and performance tests were carried out to assess the effects of the specific training program. Results showed that the pre-test value of VO2max for cycling was inversely correlated not only with the percentage of change in cycling performance, but also with the percentage change in several variables of running performance. In swimming, inverse correlations were observed between the time of the first 800 m test and the time percentage change for this test, but not with the percentage change in the performance of other segments of the race. Moreover, the somatotype component of endomorphy and the fat mass percentage of the first anthropometry were highly correlated with the percentage change in VO2max in the run segment. These results highlight the importance of providing individualised training, considering that the same training program had a different impact on recreational triathletes belonging to the same group. Amateur athletes with higher initial performance levels probably need a greater amount of training to achieve improved adaptation.

Published: July 2019

The aim of this study was to compare the activity profile (external loads) during soccer-7 competition versus 6 vs 6 small-sided games ( SSGs) in U12 players. Peak velocity (Vmax), total distance completed (DT), total distance relative to match duration, the percentage of DT in acceleration (%DAC) and in deceleration (%DEA), and the percentage of DT at different speeds were recorded. Six types of SSGs were randomly implemented: without pitch orientation-delimitation and with a limit of three ball-contacts per player (3TOU), with no limit of ball-contacts (MAN), with a greater number of players as internal-offensive wildcard players (2WI) or external-offensive wildcard players (4WE); and with pitch orientation-delimitation and crossing the rival goal-line while dribbling the ball without goalkeepers (INV) or using official goalkeepers (GKP). The physical demands of SSGs were compared with the average of two soccer-7 match plays. During soccer-7 match plays a lower %DAC and %DEA (p < 0.05) were observed compared to 2WI, 4WE, INV and GKP, and to INV and GKP, respectively. The Vmax and %HI were greater (p < 0.05) in soccer-7 match plays compared to all SSGs. In conclusion, the demands imposed on U12 players during different formats of SSGs differ from the soccer-7 match play demands, presenting a low stimulation of the actions performed at high-speed and an adequate simulation of acceleration-deceleration actions.
Sagittal and Frontal Plane Gait Initiation Kinetics in Healthy, Young Subjects
Authors: Smith Andrew W. , Wong Del P.
Published: July 2019

The study purposes were to record the lower extremity sagittal and frontal joint moments and powers during gait initiation (GI); evaluate GI support moments in both planes; and analyze planar energy patterns in a group of 15 healthy, young adults. 3D motion and ground reaction force data were used to calculate support moments (SM) and joint moments and powers as well as center of mass (COM) kinematics. STEP1 had no visible SM. It appeared in STEP2 and, by STEP3, resembled that seen in steady-state gait. Joint moments demonstrated a similar development towards typical patterns over the three steps. Correlations of moment data between planes indicate that the frontal plane component of the SM acts to keep the COM centered. It is suggested that Winter’s 1980 SM definition be extended to include both a support (sagittal) component and a centering (frontal) component. Energy was calculated for individual bursts of joint powers in both planes and each step had characteristic patterns in each plane, with patterns resembling steady-state gait appearing in the third step. Test-retest reliability (ICC range: 0.796 – 0.945) was high with CV values in the sagittal plane (36.6 – 37.5%) being less variable than in the frontal plane (39.0 – 82.0%). COM kinematics revealed that acceleration peaked in STEP2 (ICC range: 0.950 – 0.980, CV < 20.0%). Data supported hypotheses regarding the dominance of the frontal plane power in STEP1, with substantial power coming from hip flexors. As well, powers in the sagittal plane were generally of larger magnitude than in the frontal plane.

The purpose of this study was to evaluate the reliability and reproducibility of the physiological and overload features of the Yo-Yo intermittent endurance test level 2 (Yo-Yo IE2) in competitive male soccer (n = 20), basketball (n = 11), and volleyball players (n = 10). The participants completed Yo-Yo IE2 tests on three separate occasions with assessment of performance, heart rate, running speed, accelerations, decelerations and body load using GPS instrumentation. The intra-class correlation coefficient index, confidence intervals and coefficients of variation were calculated to assess the reliability of the test. Intra-class correlation coefficients for test-retest trials in the total sample ranged from large to nearly perfect (total distance: 0.896; mean speed: 0.535; maximum speed: 0.715; mean HR: 0.876; maximum HR: 0.866; body load: 0.865). The coefficients of variation for distance, mean speed, HR response, as well as acceleration and deceleration scores for test-retest trials ranged from 1.2 to 12.5% with no differences observed among particular sport disciplines. The CV for shuttles performed ranged from 4.4 to 5.5% in all sports. Similar results were obtained for the three different categories of players tested. These results suggest that the Yo-Yo IE2 test appears to be a reliable alternative for evaluating the ability to perform intermittent high-intensity running in different outdoor and indoor team sports. Players may need one or two familiarization tests to ensure valid assessment of intermittent endurance capacity. It appears that the Yo-Yo IE2 test incorporates accelerations and decelerations in a consistent and reproducible fashion.
Changes in Lower-Limb Biomechanics, Soft Tissue Vibrations, and Muscle Activation During Unanticipated Bipedal Landings
Authors: Zhang Shen , Fu Weijie , Liu Yu
Published: July 2019

We aimed to explore the biomechanical differences between the anticipated drop jump and unanticipated drop landing. Twelve male collegiate basketball players completed an anticipated drop jump and unanticipated drop landing with double legs from a height of 30 cm. Kinematics, impact force, soft tissue vibrations, and electromyographic (EMG) amplitudes of the dominant leg were collected simultaneously. The anticipated drop jump showed more flexed lower limbs during landing and increased range of motion compared to the unanticipated drop landing. The anticipated drop jump also had lower impact force, lesser soft tissue vibration, and a greater damp coefficient at the thigh muscles compared with the unanticipated drop landing. Significant increases in the EMG amplitudes of the tibialis anterior, lateral gastrocnemius, rectus femoris, and biceps femoris were observed in the anticipated drop jump during the pre/post-activation and downward phases. The anticipated drop jump presented more optimized landing posture control with more joint flexion, lower impact force, less soft tissue vibrations, and full preparation of muscle activations compared with the unanticipated drop landing.

Authors: Păsăroiu Dan , Parajkó Zsolt , Mitra Noémi , Opincariu Diana
Published: July 2019

Electrical storm is defined by at least three episodes of sustained ventricular tachyarrhythmias or appropriate shocks given by implantable cardiac defibrillator devices (ICD), occurring within a period of 24 hours. In the present manuscript, we present the case of a 69-year-old female patient with previous aortocoronary bypass, who was admitted from the Emergency Department after presenting several episodes of syncope in prehospital settings and presented 4 episodes of sustained ventricular tachycardia which required electrical cardioversion. The arrhythmia disappeared after percutaneous revascularization of a chronic occlusion in the right coronary artery. In this case, the implantation of an ICD was avoided, as a reversible cause of ES has been identified and treated.

Published: July 2019

Mangroves critically require conservation activity due to human encroachment and environmental unsustainability. The forests must be conserving through monitoring activities with an application of remote sensing satellites. Recent high-resolution multispectral satellite was used to produce Normalized Difference Vegetation Index (NDVI) and Tasselled Cap transformation (TC) indices mapping for the area. Satellite Pour l’Observation de la Terre (SPOT) SPOT-6 was employed for ground truthing. The area was only a part of mangrove forest area of Tanjung Piai which estimated about 106 ha. Although, the relationship between the spectral indices and dendrometry parameters was weak, we found a very significant between NDVI (mean) and stem density (y=10.529x + 12.773) with R2=0.1579. The sites with NDVI calculated varied from 0.10 to 0.26 (P1 and P2), under the environmental stress due to sand deposition found was regard as unhealthy vegetation areas. Whereas, site P5 with NDVI (mean) 0.67 is due to far distance from risk wave’s zone, therefore having young/growing trees with large lush green cover was regard as healthy vegetation area. High greenness indicated in TC means, the bands respond to a combination of high absorption of chlorophyll in the visible bands and the high reflectance of leaf structures in the near-infrared band, which is characteristic of healthy green vegetation. Overall, our study showed our tested WV-2 image combined with ground data provided valuable information of mangrove health assessment for Tanjung Piai, Johor, Malay Peninsula.
Industrial clusters in a post-socialist country: The case of the wine industry in Slovakia
Authors: Novotná Jana , Novotný Ladislav
Published: July 2019

Research on clusters, unlike cluster initiatives, has not been comprehensively addressed in European post-socialist countries. The aim of this paper is to explore and to analyse quantitatively the spatial organisation of economic activities in the wine industry in Slovakia, and to assess it in terms of the concept of an industrial cluster. The wine industry is considered as a production sector in which location is determined by geographical factors. The research is based on a case study of a wine region located north-east of Bratislava, Slovakia. The primary identification of the cluster potential is based on the assessment of geographic conditions and statistical analyses focused on the spatial concentration of the industry within the defined area. An extensive questionnaire survey provided data for assessing the spatial organisation of economic activities and their impact on regional competitive advantage. Despite the spatial distribution of economic activities and relations among business entities affected by socialist industrialisation and post-socialist transformation, the results show that the industrial cluster was formed in the wine industry and its performance converges with the wine clusters in traditional Western European wine regions.
Reinventing Organizations: Model of Self-Organized Process Organization (SOPO)
Authors: Kopina Dmitriy
Published: July 2019

Background and Purpose: Self-organization in teams and Business Process Orientation have been subjects of many separate researches, yet there is lack of research actually joining it within a common research. The purpose of our research is to define a research model for new type of service organization - called SOPO (Self-Organised Process Organization). This model sets research base to determine SOPO’s maturity level and a self-assessment tool, helping new emergence or transitions of existing organization toward SOPO.

Methodology: We conducted a case researches in three ICT service companies, which were undergoing a transition process towards SOPO. We conducted several in-depth, un-structured and structured part of interviews with employees holding three different positions in each organization. Hereby we present the researched organisation with most explicit case.

Results: We defined the key elements of the model and tested it in a case research. Key elements are Self-Organised Work Teams (SOWT) and Business Process Orientation (BPO). Both SOWT and BPO are positively affecting level of SOPO. Level of SOPO is positively related to both, enthusiasm of personnel to work in self-organised environment and perceived Quality of Service (QS).

Conclusion: SOPO model can be used: (1) in existing companies as a blueprint for SOPO implementation, (2) to assess the maturity level of companies reinventing their organizational structure, and (3) helping SOPO organizations to structure changes toward higher service quality. SOPO model is a viable starting point in further research. Further verification of the SOPO model by a quantitative research is needed.
Current Trends in Slovak Legislation Regulating Renewable Energy Production
Authors: Beňuš Ondrej , Čeryová Dominika
Published: July 2019

Renewable energy production is one of key actions undertaken by the EU to lower its dependency on energy imports from third countries. Renewable energy is not competitive compared to fossil fuels at this moment. Under these circumstances, there is a need for an effective legal regulation. The EU has set main targets relating renewable energy use in the directive (EU) 2018/2001. Slovak policymakers have recognized these new targets. The main objective of the paper is to examine the latest changes to the Slovak legal regulation of the renewable energy production with focus on electricity production. We analyse changes made by the amendment of the Act No. 309/2009 Coll. and provide a short explanation of new instruments.

The purchasing behaviour in the market of green products is at a low level. Consumers express their concern about the future of the planet and the cleanliness of the environment, but in their conduct they do not take into account ecological criteria. There is a discrepancy between what consumers say and what they really do. A favourable attitude to the idea of environmental protection does not translate into real action. The reasons for this gap have not been sufficiently researched yet. The aim of the research is to identify the causes of attitude-behaviour gap in the market of environmentally friendly products in Poland. To achieve the goal, the desk research and surveys were applied. The research shows that green products are well evaluated by consumers, although the knowledge about them is general and partial. Only 21% of respondents indicate knowledge of the production process, certification and control of environmentally friendly products. A large group of surveyed consumers (43%) shows willingness to pay higher prices for environmentally friendly products. But only one third of respondents (32%) declares trust in such products.
The Extended Functions of Strategic Controlling in Relation to the Value Creation of Sustainable Development
Authors: Zéman Zoltán
Published: July 2019

Strategic planning is generally performed internally and particularly by the organization. Another, lesser discussed issue of non-adequate strategic planning is that corporate management is unable to outline its long term resources without it. Supporting and ensuring the feasibility of individual set-ups of this function, which is probably the most important of all, is without doubt an expanded task of strategic control. From the managers’ point of view, the time spent on managing and controlling the individual tasks is also a type of resource to be managed. The strategy is the subject of development on a regular basis – that is, also an expanded task of strategic control – and managers should always take it into consideration alongside the operational tasks, since the design, development and implementation of strategy are affected by high-risk events of the external environment. The mapping of sustainable development at the microeconomic level is part of corporate social responsibility. Sustainable development requires global thinking and action. This is reflected in the fact that, in their economic decisions, businesses should strive for the economical use of scarce resources, achieve a balance between resource development and preservation, and ensure an appropriate dialogue, the so-called “resource” of stakeholders. The aim of the paper is to demonstrate the role of controlling in sustainable development using theoretical modelling.

Published: July 2019

The East Java Gas Pipeline (EJGP) pipeline network system is an open access for transporting almost ± 310 MMSCFD of Natural Gas from fields in East Java offshore to the onshore Power Plant consumers. The deviation between the calculated and mass balance of gas stock is called the Discrepancy in which BPHMIGAS set up a maximum value of ± 0.85%. The objective of the study is to develop a verification methodology to support hydrocarbon accounting in the EJGP Pipeline Network System. The methodology will be assisted by Flow Quantity Assurance software. After obtaining sufficient data, a new baseline can be taken empirically which can be used as a reference for the maximum allowable discrepancy in the EJGP Pipeline Network System. The data used in this simulation are taken from September - October 2013 such as pipes dimension of the entire network piping system, flowrate, pressure, temperature, and the composition of natural gas. The results of verification are compared with the calculations carried out by Pertamina Gas as operators. The calculation of Discrepancy from the Operators with different tools is around 0.12%, meaning that operator calculations are acceptable. The maximum allowable discrepancy ± 0.85%, can be reviewed to be reduced according to the history of the average system discrepancy in 2017-2018 (around 0.54%). The New Shipper from Sirasun Batur Field is still more economics by using the existing pipeline network even though it bears Discrepancy / Losses up to 1% compared to building new pipes to consumers. It is found that the discrepancy is getting smaller (reducing the error) if there is a gas balance, meaning that the end consumers will take the gas according to the agreed nomination.
Teachers' Conceptions of and Lesson Plans for Teaching Controversial Issues: Limitations for Deploying Their Pedagogical Potential
Authors: Toledo Jofre Marí­a Isabel , Gazmuri Stein Renato
Published: July 2019

Teaching "controversial issues" has a high pedagogical potential for students to understand the characteristics of social conflicts and to become critical citizens. Twenty Chilean secondary education Social Studies teachers were invited to participate in a group interview and workshop to establish their conceptions of controversial issues and to design lesson plans for teaching such issues. The data showed that although teachers recognise some of the key elements that define these issues and recognise their pedagogical potential, they do not link them with learning the characteristics of social conflict and do not seek to deepen students' understanding of the actors and interests involved in such issues. The data reveal a tension between transmitting to students an interpretation of the traumatic issue in question and creating the conditions for students to analyse the different interpretations that may be in conflict. Therefore, to deploy the pedagogical potential of controversial issues, teachers need to refrain from expressing univocal truths and to question their position as owners and transmitters of knowledge.

Background

Structural abnormalities associated with osteoarthritis (OA) are found in some patients with patellofemoral pain (PFP).

Objectives

To investigate the association between early signs of OA on magnetic resonance imaging (MRI) and characteristics from self-reported measures and physical examination in patients with PFP.

Methods

This exploratory study included data from patients with PFP from a previously published cross-sectional case-control study (n = 64; 55% female; mean ± SD age, 23.4 ± 7.0 years). Structural OA features (osteophytes, bone marrow lesions, cartilage defects, Hoffa synovitis, patellar tendon abnormalities) and quantitative T2 measurements of cartilage composition were extracted from MRI. Associations between characteristics from self-reported measures (pain at rest, pain during stair walking, knee function, duration of complaints, hours of sports participation each week), physical examination (crepitus, quadriceps strength), and early MRI signs of OA were assessed.

Results

Symptom duration was associated with bone marrow lesions in the patella (odds ratio [OR] = 1.1; 95% confidence interval [CI]: 1.0, 1.2). Sports participation (hours per week) was inversely associated with patellar tendon abnormalities on MRI (OR = 0.8; 95% CI: 0.6, 1.0). Crepitus and bilateral nature of the complaints were associated with minor patellar cartilage defects (OR = 12.0; 95% CI: 2.3, 63.6 and OR = 7.6; 95% CI: 1.1, 53.8, respectively). There were no significant associations between clinical characteristics and cartilage T2 relaxation time.

Conclusion

Presence of crepitus, bilateral complaints, a long PFP symptom duration, and reduced weekly sport participation were associated with early signs of OA in a young PFP population.

Resorcinarene Cavitand Polymers for the Remediation of Halomethanes and 1,4-Dioxane

Executive summary: Porous resorcinarene-containing polymers are used to remove halomethane disinfection byproducts and 1,4-dioxane from water.

Disinfection byproducts such as trihalomethanes are some of the most common micropollutants found in drinking water. Trihalomethanes are formed upon chlorination of natural organic matter (NOM) found in many drinking water sources. Municipalities that produce drinking water from surface water sources struggle to remain below regulatory limits for CHCl3 and other trihalomethanes (80 mg L–1 in the United States). Inspired by molecular CHCl3⊂cavitand host-guest complexes, we designed a porous polymer comprised of resorcinarene receptors. These materials show higher affinity for halomethanes than a specialty activated carbon used for trihalomethane removal. The cavitand polymers show similar removal kinetics as activated carbon and have high capacity (49 mg g–1 of CHCl3). Furthermore, these materials maintain their performance in real drinking water and can be thermally regenerated under mild conditions. Cavitand polymers also outperform activated carbon in their adsorption of 1,4-dioxane, which is difficult to remove and contaminates many public water sources. These materials show promise for removing toxic organic micropollutants and further demonstrate the value of using supramolecular chemistry to design novel absorbents for water purification.
The Electronic Structure of Water: Pulling Rabbit-Ears out of a Wave Function
Authors: Liu Yu , Frankcombe Terry J. , Schmidt Timothy
Published: July 2019

The electronic structure of water is typically thought of exhibiting lone-pairs of electrons, described by some as "rabbit-ears'". This is not the universal view, and does not mesh with an interpretation based on the one-electron wavefunctions which emerge from molecular orbital theory. Here we show, by analysing the antisymmetrized wavefunction (Slater determinant) rather than the Hartree product, that the water wavefunction indeed exhibits equivalent lone pairs. The observed photoelectron spectrum is reconciled with this view in terms of a relaxation of this structure upon the loss of an electron. It is therefore shown that the lone-pair viewpoint is completely consistent with both the experimental results and the calculated wavefunction.

Published: July 2019

The preparation of biphenyl derivatives bearing amino groups via direct cross-coupling reaction is being widely explored due to its importance for many branches of the chemical industry. One of the necessary components for such a transformation are halogenated arenes. In order to make the process more economical, we focus on inexpensive and easily available aryl chlorides which usually are not considered reagents of choice for catalytic couplings. In the following short communication, we report the results of the coupling of relatively unreactive chloroaniline with a fluorinated phenylboronic acid leading to the corresponding aminobiphenyl.
