The design of this study is a descriptive study using quantitative data. In this study, the population identified consists of 204 4th year students of the School of Education, Faculty of Social Science and Humanities who attended the Bachelor of Technology with Education in Mechanical Engineering (SPPJ), Buildings (SPPQ), Electrical and Electronic (SPPR) and Living Skills (SPPH). A total of 180 samples were identified based on sampling formula and the instrument used was a set of questionnaire with reliability value of α = 0.86 which contained 48 items in part B based on multiple intelligence and respondent demographic in part A. The study data was processed using Statistical Package for Social Sciences SPSS version 25 to get the results of the study in the form of descriptive analysis like percentage, frequency, mean score and standard deviation while inference analysis with independent T-test to find mean difference between gender. The findings show that each student has more than one intelligence for each respondent and the intelligence of Naturalist, Intrapersonal, Verbal Linguistics and Kinestatic Body is the dominant intelligence of the students. In addition, the findings showed that there was no significant difference between the multiple intelligences and the gender of the students. In conclusion, intelligence varies by individual and is unrelated to gender and intelligence can be enhanced through education and experience.

In an increasingly knowledge-based society, social cohesion can be built through government policy, such as open access to the similar resources required for all groups. Reflecting on the setting, this study emphasizes the social resources that exist within the community itself. In this sense, it referred to kinship relations between the two religious’ groups, namely Catholicism and Islam. By using a qualitative approach and the concept of social cohesion, this study found that the two religious groups who are living together as one community in the inland or rural in West Manggarai district have the same family background. In consequence, the social obligations that they receive solely based on it, regardless of religious differences. This study, therefore, concluded that the background of the same family relationships contributes to creating social cohesion in society.

Published: September 2019

Earnings is an indicator of corporate performance evaluation. This study examines the role of leverage and corporate governance on earnings quality in banking companies in Indonesia. The results of the study indicate that higher leverage reduces the Earnings Quality. The high level of leverage indicates that the company has a large burden to pay off debt, so that it influences financial performance, especially profits. This model is consistent with previous empirical research. The age of firm, the proportion of commissioners’ board and the number of audit committees as the implications of Corporate Governance have no significant effect on earnings quality. This research model is not consistent with the results of previous studies on the effect of corporate governance on Earnings Quality.

It is important for politicians to have a good argumentative skill. For state leaders, the ability to think logically, to use rhetoric, and to argue systematically, scientifically, sharply, and eloquently is very crucial. The year 2019 is the political year for Indonesia. Political campaigns leading to the presidential and the legislative election, both in national and regional levels, will happen in 2019. The focus of this research is to investigate the depth and breadth of the arguments stated by the presidential candidates and how those arguments are presented. The research substantial data source is in the form of speech transcript of the recorded video of the first-round presidential debate by two pairs of president and vice-president candidates. The research data were the debate arguments found in the video transcript and the contexts surrounding them. The data gathering method used observation by employing recording and note-taking techniques. After the data were gathered, they were selected and classified based on their types for further analysis. The analysis method was distributional method and content analysis. Both data analysis methods were applied to yield significant results of the study. The results showed that there are simple patterns of argument containing claim, subclaim, data, and warrant. The orders of elements of arguments might be varied. The research results also showed that there were various pragmatic meanings found in the arguments used by the president and vice-president candidates. The results of the study which was analyzed using the critical pragmatic perspective reflect how far the candidates were concerned with the marginalized, the underprivileged, and the subjugated people.

This article analyzes the effect of several economic, environmental and social determinants for the per capita demand for water in Libya. Besides prices, income and population size, the article reflects the impact of urban population size, the temperature, summer temperature, and precipitation. The article also explores why the current per capita residential water demand in the urban areas is about more than in the other areas in Libya. In this study, the econometric model based on E-views method, instrumental-variable procedures, the ARDL model and the demand equation are applied. The co-integration analysis has shown a significant positive effect of temperature on water demand over the short and long term with partial flexibility of long-term temperature (5.44). Also, there is a positive relationship between rainfall and water demand in the long term and its less impact in the short term. There is a significant positive relationship between urban population and water demand. The greater urban population is greater the water demand and vice versa, partial flexibility of the urban population in the long term is at 0.23. On the other hand, there is a significant negative effect of income on water demand. Therefore, water demand is inflexible to changes in income. The study demonstrated that there is a negative effect on water price in relation to water demand. The estimated long-term variable of water value is 220.98, indicates that if the water price increases by 100%, the demand for water will go down by 221%.

The workplace-readiness of the Malaysian graduates is unarguably an issue that the local employers and the Higher Education Providers (HEPs) have a consensus upon. It has been reported by the Malaysian Employers’ Federation that more often than not the disability or handicap lies in the poor communicative ability of the graduates who failed to impress their future employers despite their sterling academic performance. One of the hiring criteria for the future employers is that these graduates must be trained to be more verbally competent and eloquent. Hence, this study attempts to conduct a performance analysis of a group of local undergraduates in their English Exit Test (EET) that is made up of written and spoken assessments for them to be workplace-compliant. However, the result has indicated that the test-takers tend to be inhibited when it comes to expressing themselves verbally, which has resulted in a dismal performance in the speaking component. As such, it is a cause for concern to rectify the situation and figure out the solutions to tackle their weak performance. This study also analyses the different performance between the Engineering as opposed to the Hotel Management and Tourism undergraduates, in which a slight difference in their achievement of grades was found. The five dissimilar disciplines of speaking tasks also recorded a difference in their score means achieved by the test takers, which could suggest that treatments are in need to be tailored for those weak performers

Conversion of CO2 to High Value Products
Authors: Nath Nibedita
Published: September 2019

Due to human activities and rapid industrialization, the amount of CO2 emitted into the atmosphere increases by the day. It is an environmental pollutant and is indirectly responsible for causing climate change and global warming. Thus, research has been carried out for the conversion of CO2 into value added chemicals. However, CO2 is a chemically-inert and thermodynamically-stable molecule; thus, external energy should be supplied or a suitable catalyst should be designed for their conversion into useful chemical. Methanol, dimethyl ether, higher alcohols, methyl, formic acid, formaldehyde, organic carbonates, etc. are the different chemicals that are prepared from CO2. CO2 is an environmentally friendly raw material as it is nontoxic, abundant, and economical. A lot of research has been carried out on the reaction using CO2 as a raw material. This chapter mainly focused on synthesis of various chemicals from CO2 as a raw material.

Characterization of dredged sediments: a first guide to define potentially valuable compounds – the case of Malmfjärden Bay, Sweden
Authors: Ferrans Laura , Jani Yahya , Gao Ling , Hogland William
Published: September 2019

Abstract. Millions of tons of bottom sediments are dredged annually all over the world. Ports and bays need to extract the sediments to guarantee the navigation levels or remediate the aquatic ecosystem. The removed material is commonly disposed of in open oceans or landfills. These disposal methods are not in line with circular-economy goals and additionally are unsuitable due to their legal and environmental compatibility. Recovery of valuables represents a way to eliminate dumping and contributes towards the sustainable extraction of secondary raw materials. Nevertheless, the recovery varies on a case-by-case basis and depends on the sediment components. Therefore, the first step is to analyse and identify the sediment composition and properties. Malmfjärden is a shallow semi-enclosed bay located in Kalmar, Sweden. Dredging of sediments is required to recuperate the water level. This study focuses on characterizing the sediments, pore water and surface water from the bay to uncover possible sediment recovery paths and define the baseline of contamination in the water body. The results showed that the bay had high amounts of nitrogen (170–450 µg L−1), leading to eutrophication problems. The sediments mainly comprised small size particle material (silt, clay and sand proportions of 62 %–79 %, 14 %–20 %, 7 %–17 %, respectively) and had a medium–high level of nitrogen (7400–11 000 mg kg−1). Additionally, the sediments had little presence of organic pollutants and low–medium concentration of metals or metalloids. The characterization of the sediments displays a potential use in less sensitive lands such as in industrial and commercial areas where the sediments can be employed as construction material or as plant-growing substrate (for ornamental gardens or vegetation beside roads).

A presente revisão sistemática teve o objetivo de investigar a contribuição dos estudos de neuroimagem na investigação do priming semântico (PS) avaliado através de tarefas de decisão lexical em artigos publicados entre 2001 até setembro de 2017. Foram incluídos estudos com tarefas de decisão lexical com estímulos visuais e auditivos. A revisão resultou em 19 artigos, os quais mostraram o efeito de PS em uma diversa rede de áreas cerebrais (lobo frontal e temporal, giro cingulado, área motora suplementar e córtex parietal). A identificação de ativação nestas redes variou em função do intervalo entre estímulos utilizado. Os dados sugerem que ambos hemisférios estão envolvidos no efeito de PS, com o hemisfério esquerdo apresentando um papel mais robusto. Diminuição da ativação no giro temporal medial esquerdo foi associada ao efeito de PS automático. Esta mesma área apareceu relacionada ao efeito de PS com longos intervalos entre os estímulos, juntamente com o giro frontal inferior esquerdo e o córtex cingulado anterior. Um forte papel do hemisfério esquerdo nas tarefas de PS pode ser observado, especialmente do giro temporal medial esquerdo. Sua ativação foi modulada pelos curtos ou longos intervalos entre estímulos sendo mais ativação associada com longos intervalos.

African mahogany is an exotic specie and its cultivation has increased in Brazil due to the high value of its timber on the international market. Nutrition with nitrogen is an important factor for species with high biomass production and specific studies on this species are essential. The present study aimed to assess the initial growth of African mahogany plants submitted to nitrogen fertilization. The experiment was set up and carried out in a greenhouse, with 7 dm3 plastic pots using a oxisoil sampled from the surface layer. A completely randomized experimental design was used with five treatments and six replications. The treatments consisted of five N levels: 0, 40, 80, 120 and 160 mg dm-3, using urea as the source. The following were assessed at 180 days: height, stem diameter, leaf, stem, root and total dry matter, N content in the leaves in the African mahogany leaves. The African mahogany seedlings had high N demand and responded positively to the N used and the growth variables was positive with increase in N level. However, as it presented increasing linear effect, the N level can not be estimated, that would provide the maximum initial development for this plant species.

Published: September 2019

Invasive plants may present allelopathic substances that interfere with the germination and initial development of seedlings of various species. The objective of this study is to evaluate the physiological quality of cabbage and tomato seeds in the presence of different concentrations of purple nutsedge extract. The seeds were left to germinate in different substrates. Individual experiments were performed for both species. Five concentrations (0, 25, 50, 75 and 100%) of aqueous extract obtained from tubers of Cyperus rotundus were used. The seeds of each species were placed to germinate in three types of substrates (sand, commercial, and paper). Germination, normal seedlings, abnormal seedlings, non-germinated seeds, germination speed index, and accelerated aging were evaluated. A completely randomized experiment with a 3 × 5 factorial design (three substrates and five concentrations of purple nutsedge extract) was conducted with four replications. For the substrates, the means were compared by Tukey test at 5% probability. Polynomial regression analyses were carried out for concentrations of purple nutsedge extract. Cyperus rotundus exerts allelopathic effects on the germination of tomato and cabbage seeds. As the concentration of the tuber extract increases, the inhibitory effect increases, thus reducing germination and seed vigor in the different substrates. The commercial substrate for tomato and the paper substrate for cabbage may minimize the allelopathic effects of Cyperus rotundus extract during germination of seeds.
Effect of the Rhizospheric Micro-organisms of Some Fabaceaes and Peat Substratum on the Growth of Carob Tree (Ceratonia siliqua L.)

Published: September 2019

Intensive exploitation of sand quarry sites inevitably results in near total destruction of plant cover and soil degradation. The damage done is so important that without human intervention, soil scarification and vegetable return to growth may take several decades. In order to conduct a site rehabilitation programme successfully reforestation through the plantation of a native species such as the carob tree (Ceratonia siliqua) should be the appropriate choice. Because of their facilitation effect, the spontaneous leguminous plants present in the site, specifically Lotus creticus, Retama monosperma and L. creticus associated with R.monosperma can be used as nurse plants. Our assumption is that they possess a rhizosphere rich in microorganisms, which may positively impact the growth of carob. To this end, a study is conducted in order to: a) estimate the diversity of arbuscular mycorrhiza fungi (AMF) living underneath the spontaneous leguminous plants of the site; b) determine their combined effect with other microsymbionts (i.e., total bacteria and actinobacteria) on the growth of the carob tree; c) draw a comparison with carob grown in bare soil and in sterile soil mixed with peat regarding its growth parameters and mineral nutrition. The trees were grown in plastic pots under greenhouse conditions and, after 12 months, the results have shown that, against all odds, the soils of R. monosperma and L. criticus associated with R. monosperma do not significantly influence the growth of the tree whereas the impact of the soil of L. creticus is outright negative. On the other hand, peat improves the root and aerial growth of the tree, which shows in leaves number, branch number and capacity of nutrition in nitrogen. Because a little richer in actinobacteria, bare soil increases the length of the aerial parts and improves the tree’s phosphorus uptake.
“Cancer in the family” and genetic testing: implications for life insurance
Authors: Lynch Elly L , Doherty Rebecca J , Gaff Clara L , Macrae Finlay A , Lindeman Geoffrey J
Published: September 2019

The potential for discrimination when applying for insurance can be of concern for individuals with a family history of cancer or of a genetic disorder and who are considering genetic counselling or genetic testing. The actual incidence of “genetic discrimination”, however, is not known, despite considerable media coverage of this issue.

The clinical details required by insurers have received less attention. We obtained primary application and personal statement forms used by 21 different underwriters of voluntary life insurance and found substantial differences in the information requested about family history and genetic testing.

All insurance applications, however, contained a duty of disclosure that would require revealing the result, if known by the applicant, of a genetic test in a family member. Therefore, decisions made by family members can affect insurance applications, and people considering genetic testing may also need to consider the implications of the results for other family members.

Health practitioners should balance the potential benefits of appropriate genetic testing against potential restriction to life and income‐protection insurance when advising people about genetic testing.
Evidence‐based guidelines for fixing broken hips: an update
Authors: Chilov Michael N , Cameron Ian D , March Lyn M
Published: September 2019

Objective: To update evidence‐based guidelines for the treatment of proximal femoral fractures published in the Journal in 1999.

Data sources: Systematic literature search of MEDLINE, CINAHL and EMBASE from January 1996 to September 2001 and the Cochrane Database of Systematic Reviews (most recent issue searched — Issue 2, 2002).

Study selection: Randomised controlled trials and meta‐analyses of all aspects of acute‐care hospital treatment and rehabilitation of proximal femoral fractures among subjects aged 50 years and over with proximal femoral fractures not associated with metastatic disease or multiple trauma.

Data extraction: All studies were read independently by two reviewers. Reviewers recorded individual study results, and an assessment of study quality and treatment conclusions according to Cochrane Collaboration protocols. If necessary, a third review was performed to reach consensus.

Results: 93 new studies were identified and 82 met our inclusion criteria. Recommendations for thromboprophylaxis, anaesthesia, surgical fixation of fractures and nutritional status have been altered to incorporate new evidence. Recommendations have been added regarding postoperative blood transfusion, the management of subtrochanteric fractures, and the type of surgical swabs which should be used.

Conclusions: Although there have been few significant changes to the previous recommendations, updating the guidelines has required substantial effort. The common clinical problem of hip fracture should be treated according to the most up‐to‐date evidence to achieve the best possible outcomes and optimal utilisation of limited resources. Guideline updates also require resourcing.
Vocal interactivity in crowds, flocks and swarms: implications for voice user interfaces
Authors: Moore Roger K
Published: September 2019

Recent years have seen an explosion in the availability of Voice User Interfaces. However, user surveys suggest that there are issues with respect to usability, and it has been hypothesised that contemporary voice-enabled systems are missing crucial behaviours relating to user engagement and vocal interactivity. However, it is well established that such ostensive behaviours are ubiquitous in the animal kingdom, and that vocalisation provides a means through which interaction may be coordinated and managed between individuals and within groups. Hence, this paper reports results from a study aimed at identifying generic mechanisms that might underpin coordinated collective vocal behaviour with a particular focus on closed-loop negative-feedback control as a powerful regulatory process. A computer-based real-time simulation of vocal interactivity is described which has provided a number of insights, including the enumeration of a number of key control variables that may be worthy of further investigation.

The current debates about the future of academic publishing have generated much discussion about the most appropriate way to support financially the widespread circulation of knowledge. Yet there have been debates about this since at least the 1890s. Drawing upon my historical research, I will describe how scholarly publishing has a long history of not making money. Indeed, until the mid-twentieth century, its costs were frequently sponsored (i.e. subsidised) by learned societies, by universities, by government and by private donors. It was only in the early Cold War years, in a time of expanding output of research, that mission-driven publishers began to seriously focus on sales income as a means of covering costs; and then, later, as a means of generating income. Should publishing be treated as mission, or as a means to mission? My talk will seek to untangle the historical relationship between publishing, money-making and scholarly mission.
Improvement of equivalent magnetic coupling coefficient of wireless power transfer system with multiwinding transmission coil

Published: September 2019

This article proposes a novel method of improving the overall coupling coefficient of a wireless power transfer system by using a four‐winding transformer of which two pairs of windings each are connected in parallel in the primary side and secondary side. By weakening the coupling coefficients kc between the parallel windings, the overall magnetic coupling between the primary side and secondary side of the transformer is improved. In order to confirm the validity of the proposed method, a conventional high‐kc four‐winding transmission coil and the proposed low‐kc four‐winding transmission coil are experimentally assessed. Then, the coils are introduced into a nonresonant inductive power transfer system utilizing a dual active bridge converter in order to confirm the correction of the input power factor. As a result, the overall magnetic coupling of the proposed four‐winding coils was found to be improved by 17% compared with the overall magnetic coupling of the conventional coil. Moreover, the input power factor for the entire load is corrected with the proposed four‐winding coil. Therefore, a low kc is effective in improving the overall magnetic coupling.

Background:

Rapid eye movement (REM) sleep behavior disorder (RBD) and REM sleep without atonia (RWA) have assumed much clinical importance with long-term data showing progression into neurodegenerative conditions among older adults. However, much less is known about RBD and RWA in younger populations. This study aims at comparing clinical and polysomnographic (PSG) characteristics of young patients presenting with RBD, young patients with other neurological conditions, and normal age-matched subjects.

Methods:

A retrospective chart review was carried out for consecutive young patients (<25 years) presenting with clinical features of RBD; and data were compared to data from patients with epilepsy, attention deficit hyperactivity disorder (ADHD), and autism, as well as normal subjects who underwent PSG during a 2-year-period.

Results:

Twelve patients fulfilling RBD diagnostic criteria, 22 autism patients, 10 with ADHD, 30 with epilepsy, and 14 normal subjects were included. Eight patients with autism (30%), three with ADHD (30%), one with epilepsy (3.3%), and six patients who had presented with RBD like symptoms (50%) had abnormal movements and behaviors during REM sleep. Excessive transient muscle activity and/or sustained muscle activity during REM epochs was found in all patients who had presented with RBD, in 16/22 (72%) autistic patients, 6/10 (60%) ADHD patients compared to only 6/30 (20%) patients with epilepsy and in none of the normal subjects.

Conclusion:

We observed that a large percentage of young patients with autism and ADHD and some with epilepsy demonstrate loss of REM-associated atonia and some RBD-like behaviors on polysomnography similar to young patients presenting with RBD.

During the rubber long-term storage in the open air and under the influence of certain temperatures, there is a real threat to the environment where environmental damages cannot be ignored. The objective of this paper is to study the mechanical properties of rubber during its processing by vulcanization after adding some materials to improve their properties. The used materials are: rubber from tires where the proportion of rubber varies from 70-78%, vulcanization granules of rubber, non-vulcanized natural NR rubber, and granulated sulphur. Curves of stress-strain of the recycled rubber are modelled at different diameters of the granules added to the materials for vulcanization removal. As result, the improvement of the mechanical properties are obtained by increasing the diameter of the granules but there a threshold which should not be exceeded.
The vibroisolation effectiveness of fiber reinforced natural composites compared to the elastomer materials produced from non-renewable resources

In this work, a number of test were carried out to evaluate the effectiveness of the vibroisolation composite consisting of a biodegradable polymer matrix (polylactid actid, PLA) and filler in the form of natural flax fibers, with a moisture content of 2.03% after drying in 80°C for 4 hours. To improve material dampening properties, PLA was plasticized with polyethylene glycol (PEG 400) and triethyl citrate (TEC). The flax fiber content of the composite was: 10, 20, 30 wt.%. Mechanical properties at bending and tensile were performed. For measurement of vibroisolation effectiveness, composite samples have been made the enable installation in the measurement system. The measuring system consisted of an unbalanced axial electric motor, resting on a steel frame placed on vibroisolators. For comparison the commercial grade vibroisolators were used. In order to evaluate the vibration damping of the system by vibroisolators, vibration engine frame vibration was forced by acceleration of the engine’s rotational speed to specific frequencies. It has been proven that the type of the plasticizer used in the composite changes the vibroisolation parameter. Also length and weight%. of the fibres results in lower material damping values.

The carbon sink capacity of the forest makes forest conservation a mitigation mechanism against climate change. Therefore, carbon sequestration studies allow to assess forest productivity and control carbon budgets. Thus, the changes in environmental parameters (carbon amount in humus and phytomass) as effect of the increase of CO2 emissions, deforestation and erosion were calculated for countries of the Central and South between 2000 and 2060 through the Spatial Mathematical Model of the Global Carbon Dioxide Cycle in the biosphere. The majority of countries show a decrease in total carbo of humus and phytomass between 2000 and 2010, which is attributed to the extreme deforestation that they suffered. Subsequently, there is a moderate increase in countries that has better polices in favour of environmental protection. Finally, in all countries an exponential increase until 2060 is observed, which is expected thanks to forest conservation, reforestation policies and the compensatory effect between the atmosphere and forests. The highest values of total carbon belong to one country in the Caribbean (Belize with 21,5%). This analysis is useful for planning environmental practices in order to increase carbon storage.
15 years of acoustic detection studies at INFN

Since the early 2000s, thanks to national, regional and European projects, a number of abyssal detectors equipped with acoustic sensors have been installed and operated by INFN in two cabled submarine research infrastructures off Eastern Sicily. The INFN’s interest in underwater acoustics arises from the need to develop an acoustic positioning system for the KN3NeT telescope and to study the possibility of neutrino acoustic detection. Theuse of innovative technologies for data acquisition and transmission systems have enabled the first long-term studies on the deep marine environment of the Ionian Sea with a variety of lines of research. Data acquired through the INFN underwater infrastructures have allowed the continuous monitoring of the underwater acoustic noise and several studies on cetacean species present in the area and on seismic sources . An overview of the main activities of INFN on detection and localization of underwater acoustic sources will be presented.
