Authors: Fajrin Jauhar , Hariyadi Hariyadi , Marchelina Nadella
Published: July 2018

Sebagai bahan bangunan yang relatif masih baru, komposisi bahan penyusun bata non-bakar masih menjadi topik yang menarik untuk diteliti. Pada beberapa studi sebelumnya upaya mencari komposisi optimum campuran bata non bakar menggunakan metode eksperimen yang mengevaluasi pengaruh sebuah faktor dalam satu kali eksperimen atau yang dikenal dengan istilah single factor experiment. Kelemahan dari metode eksperimen ini adalah kesimpulan yang dihasilkan hanya terkait dengan satu faktor yang diamati itu saja. Sementara dalam kenyataannya, hasil dari sebuah proses tidak hanya dipengaruhi oleh satu faktor saja melainkan dipengaruhi oleh banyak faktor termasuk interaksinya. Studi ini dilakukan untuk mencari komposisi optimum bahan penyusun bata non bakar dengan menerapkan metode respon permukaan (Response Surface Method). Proses analisa data dilakukan dengan menggunakan software Minitab 17. Hasil penelitian menunjukan bahwa proporsi bahan yang menghasilkan kuat tekan paling optimal adalah semen (21,034%), pasir (28,9651%) dan tanah liat (50%), yang mampu menghasilkan bata non bakar dengan kuat tekan rata-rata sebesar 50.22 kg/cm2. Hasil penelitian ini juga merekomendasikan sebuah persamaan umum untuk memprediksi kuat tekan bata non bakar apabila menggunakan ketiga komposisi bahan tersebut, yaitu: y=-5,56x1+0,141x2+0,541x3+0,214x1 x2+0,0473x1 x_x-0,307x2  dengan x1, x2 dan x3 masing-masing adalah proporsi semen, pasir dan tanah liat.

Kabupaten Pacitan dikenal dengan “Kota 1001 Goa” dan salah satu ikonnya adalah Goa Gong. Ketersediaan fasilitas parkir yang memadai merupakan salah satu faktor yang menentukan tingkat kunjungan wisatawan. Bertambahnya jumlah wisatawan berpengaruh terhadap volume parkir. Penelitian ini bertujuan untuk mengevaluasi fasilitas parkir di Objek Wisata Goa Gong dan memberikan alternatif penanganan masalah fasilitas parkir dan aksesibilitas untuk pengembangan Objek Wisata Goa Gong. Data primer diperoleh dengan melakukan survei lapangan yang dilaksananakan pada hari Sabtu dan Minggu, berupa data nomor plat kendaraan, waktu kendaraan masuk dan waktu kendaraan keluar area parkir. Data sekunder diperoleh dari instansi terkait berupa data volume parkir tahun 2011-2016. Prediksi volume parkir tahun 2022 dilakukan dengan metode regresi berdasarkan data volume parkir tahun 2011-2016.Berdasarkan hasil analisis data, indeks parkir rata-rata di area parkir Objek Wisata Goa Gong tidak terlalu tinggi, tetapi pada jam-jam tertentu indeks parkir mencapai lebih dari 70 %. Jika indeks parkir lebih dari 70 %, pengguna parkir akan kesulitan dalam memperoleh ruang parkir. Hasil prediksi volume parkir pada tahun 2022 mencapai 20868 kendaraan untuk sepeda motor, 19776 kendaraan untuk mobil, dan 6120 untuk bus. Prioritas penanganan masalah adalah penambahan kapasitas parkir termasuk penyediaan fasilitas pendukung lainnya, misalnya pemisahan pintu masuk dan keluar area parkir, pemasangan mesin/pintu parkir otomatis pada pintu masuk dan keluar area parkir, pembuatan zebra cross serta penyediaan angkutan untuk wisata. Penerapan manajemen parkir dan penegakan peraturan yang tegas juga diperlukan dalam upaya pengembangan Objek Wisata Goa Gong.

Non linear Mixed Effects Models: Bridging the gap between Independent Metropolis Hastings and Variational Inference
Authors: Karimi Belhal
Published: July 2018

Variational inference and MCMC methods have been two popular methods in order to sample from a posterior distribution. Whereas the former extends the computation feasibility to higher dimension, the latter takes advantage of nice convergence properties to the exact posterior distribution. In this work we'll draw the parallel between a famous MCMC scheme called the Independent Metropolis Hastings and Variational inference. We'll explain our work on both Linear and Non-linear Gaussian cases. In the non linear case, a new proposal will be introduced motivated by a faster convergence of the Markov chain.

Pakistan's Development — The Role of Government and Private Enterprise
Authors: Swadesh R. Bose
Published: July 2018

In the 1960's Pakistan's economy started generating rates of growth of over 5 per cent per year—higher than those observed in many other underdeveloped countries including its neighbours. Industry is growing rapidly. Exports are increasing by over 7 per cent per year. Perhaps more significant, many believe, an agricultural revolution is underway. Some observers consider this to be remarkable and a model of development in the non-socialist world. However, the brief growth experience of the 1960's, after the long stagnation during the 1950's, can hardly be a basis for definitive conclusions about long-run development. Observation of a longer period and evidence of certain basic conditions are necessary for such extrapolation. The dependence on foreign aid continues to be large and the domestic saving rate is relatively low. It is too early to talk of self-sustaining growth. How and why Pakistan could achieve this development and what it signifies for the country's future growth is surely of interest. Yet apart from some spotty reviews of progress, mainly from official sources, no systematic and comprehensive study of Pakistan's development process explaining its mechanism had been available. Dr. Papanek's book on Pakistan's development [13] is an important contribution in this field. The author analyses the factors that led to development in the past, and drawing upon that experience, suggests policies that would accelerate future development. He tries to explain how the saving rate was raised in a poor country of traditional agriculture, where industrial investors came from, how agricultural output could be increased at a high rate, and what role government and private initiative played in this development. Any analysis of the role of government and private enterprise has ideological overtones, and the reader of Dr. Papanek's book is definitely aware of his in¬dividual predilections. This does not, however, reduce the worth of the book.
Mitä on toisen kielen sujuvuus? Näkökulmia kognitiivisen ja puhetuotoksen sujuvuuden tutkimuksesta
Authors: Olkkonen Sanna , Peltonen Pauliina
Published: July 2018

In this review article, we combine two approaches to the study of second language (L2) fluency: cognitive fluency and utterance fluency. The former concentrates on cognitive processing and its limitations, whereas the latter involves analyzing fluency-related features from speech samples. Despite theoretical links, the research traditions associated with the approaches have been relatively separate. In addition to providing an overview of the two approaches, the similarities and differences between them are illustrated with results related to one aspect of (dis)fluency, repetitions. Bringing together results related to cognitive and utterance fluency highlights the usefulness of combining different viewpoints in L2 fluency research and demonstrates the need for further interdisciplinary dialogue to gain a comprehensive picture of L2 fluency. Together, the results of studies emphasizing different aspects of L2 fluency also have important implications for L2 fluency assessment.

An extended Chinese remainder system
Authors: Nguyen Thinh D.
Published: July 2018

Chinese remainder theorem is a widely-known result in number theory proven by Euler, according to Wikipedia. The proof actually yields an efficient method to solve a modular system with pair-wise coprime moduli. With a little improvement, we are able to extend the method to non-coprime moduli (by using lcm, gcd to manipulate each pair of moduli). Now, to add more flavor to this well-studied problem, we extend each modular congruence to a multi-choice one. With the system consisting of multi-choice congruence like this, how efficient can your algorithm solve it? We show that if one has ever loved reading Prasolov's books including geometry, number, discere maths, then one can move on reading several words below to deduce that this extended problem is not an easy one.

Authors: Yauri Indriani , Nash Robyn , Ramsbotham Joanne
Published: July 2018

Background: Utilizing expert panel in content validity evaluations of new constructed educational packages in the nursing context have not been described well.Objective: to describe the use of expert panel in a content validity evaluation of a new clinical reasoning educational package.Methods: Five senior nursing academics participated in the study. The prospective panellists were selected based on their relevant professional expertise, including teaching experience, relevant academic qualifications, and practice experience in the Indonesian context. The specifically constructed feedback instrument consisted of 31 items encompassing an overview of the educational-intervention model, the student’s workbook and the teacher’s guide. A Likert scale was used to evaluate the relevance, clarity and feasibility of the educational intervention package. The review was conducted over a period of approximately five weeks. Numerical data were analysed using the Content Validity Index (CVI) method. Both Item (I-CVI) and Scale (S-CVI) levels were calculated. An I-CVI of ≥.78 and an S-CVI of ≥.90 are determined. Panellists’ written comments were also sought. Thematic analysis was undertaken to analyse the qualitative data. Findings were used to inform decisions about whether to retain, modify or eliminate each item.Results: The I-CVI scores for each sub-scale (relevance, clarity and feasibility) was ≥.93.The S-CVI for the educational overview, teacher and student’s guides was ≥.95. Accordingly, the average proportion of expert agreement on the educational-intervention package was .98. The package as a whole (and the three individual components: overview, teacher’s and student’s guides) was shown to have excellent content validity. Comments from the panellists are focus on the teacher’s preparation before using the educational package. Thus, no further improvement on the educational package was required.Conclusion: Utilizing expert panel content validity and critically evaluating their recommendations can result in a more relevant, clear and feasible educational intervention, leading for a more effective clinical reasoning educational approach for student nurses.

Effect of the Critic’s Group Status and Length of Stay on Intergroup Sensitivity Effect
Authors: Mantara Angga Yuni
Published: July 2018

This study aims to determine the effect of group membership (outgroup, Ex-outgroup) and length of stay (long, short) to intergroup sensitivity effect (ISE). Earlier ISE studies only focused on outgroup and ingroup critics, and showed that outgroup critics tend to be rejected and perceived more negative than ingroup critic. This quasi-experiment study further examined critics from outgroup and ex-outgroup (N = 185, Mage = 21,58). ISE is measured by the degree of likeability, constructiveness, negativity, and agreeableness to critic from outgroup and ex-outgroup. We predict that critic from outgroup will reveal a stronger ISE than ex-outgroup critic who had stayed longer in Indonesia. The results showed that there are significant effects of group membership status to agreeableness, and length of stay to constructiveness. Furthermore, the interaction between the critic and length of stay affects only occurred when the speaker’s length of stay is short.
Open Science in Data-Intensive Psychology and Cognitive Science
Authors: Paxton Alexandra , Tullett Alexa Mary
Published: July 2018

Today, researchers can collect, analyze, and share more data than ever before. Not only does increasing technological capacity open the door to new data-intensive perspectives in cognitive science and psychology (that is, research that takes advantage of complex or large-scale data to understand human cognition and behavior), but increasing connectedness has sparked exponential increases in the ease and practice of scientific transparency. The growing open science movement encourages researchers to share data, materials, methods, and publications with other scientists and the wider public. Open science benefits data-intensive psychological science, the public, and public policy, and we present recommendations to improve the adoption of open science practices by changing the academic incentive structure and by improving the education pipeline. Despite ongoing questions about implementing open-science guidelines, policymakers have an unprecedented opportunity to shape the next frontier of scientific discovery.

Authors: Holt Nicola Jane , Furbert Leah , Sweetingham Emily
Published: July 2018

The current research sought to replicate and extend work suggesting that coloring can reduce anxiety, asking whether coloring can improve cognitive performance. In two experiments undergraduates (N = 47; N = 52) colored and participated in a control condition. Subjective and performance measures of mood and mindfulness were included: an implicit mood test (Experiment 1) and a selective attention task (Experiment 2) along with a divergent thinking test. In both experiments coloring significantly reduced anxiety and increased mindfulness compared with control and baseline scores. Following coloring participants scored significantly lower on implicit fear, than the control condition, and significantly higher on selective attention and original ideation. Coloring may not only reduce anxiety, but also improve mindful attention and creative cognition.
Explore/exploit tradeoff strategies in a resource accumulation search task
Authors: Sang Ke , Todd Peter M. , Goldstone Robert , Hills Thomas
Published: July 2018

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation tradeoffs by using a novel card selection task. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants’ behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants’ results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.
Challenges of IS Research Translation: a Study of Tensions between ICT Innovation and Conservative Bureaucracies
Authors: Hasan Helen , Connery Andrew , Crawford Kate
Published: July 2018

In highly-structured public bureaucracies, such as universities, the need for stable and ordered administration conflicts with attempts at innovation and creativity. This is a particular dilemma for universities, which exist to create and share knowledge. The case presented here concerns the tensions generated where a university’s administration ignored innovative IS research findings which could translate into innovations from which they could benefit. We employ Leximancer to objectively analyse textual documents related to the case and invoke Activity Theory to make deeper sense of the phenomenon of our investigation. Identifying several contractions behind the tensions uncovered in this case, we turn to the concept of dialectic as a tool for cooperatively resolving complex contradictions. The findings concern many cultural-historical factors that present barriers to the translation of IS research into innovative practice in university administration.

The spread of hoaxes in social media has raised some concerns. Various efforts have been made by the government to minimize its distribution. However, a number of cases related to hoaxes that contain slander and hatred of the Ethnic, Religion, and Race increase over the past three years. This research seeks to find out what strategic and policy steps have been taken by the government. The results show that the government attempted to minimize the distribution of hoax by issuing a number of regulations and supporting infrastructure. That regulation is not optimal because there are some weaknesses contained in the regulation. The existing regulations only address a number of anticipatory steps that must be taken and do not address the root causes of the spread of hoax. On the other hand, the government is also not optimal in coordinating across agencies. And, the government is not optimal to provide media literacy to the community of social media users. Media Literacy is important to make media users have the ethic when interacting in cyberspace

Data from a large autopsy series were analyzed to address questions pertinent to primary age-related tauopathy (PART) and Alzheimer’s disease (AD): what factors are associated with increased severity of neurofibrillary degeneration in brains that lack neuritic amyloid plaques?; is there an association between Apolipoprotein E ( APOE) alleles and PART pathologic severity independent of amyloid- β (A β) deposits?; and, how do the stains used to detect plaques and tangles impact the experimental results? Neuropathologic data were evaluated from elderly research volunteers whose brain autopsies were performed at University of Kentucky Alzheimer’s Disease Center (UK-ADC; N = 145 subjects). All of the included subjects’ brains lacked neuritic amyloid plaques according to the CERAD diagnostic criteria and the average final MMSE score before death was 26.8±4.6 stdev. The study incorporated evaluation of tissue with both silver histochemical stains and immunohistochemical stains to compare results; the immunohistochemical stains (A β and phospho-tau) were scanned and quantified using digital pathologic methods. Immunohistochemical stains provided important advantages over histochemical stains due to sensitivity and detectability via digital methods. When AD-type pathology was in its presumed earliest phases, neocortical parenchymal A β deposits were associated with increased medial temporal lobe neurofibrillary tangles. The observation supports the NIA-AA consensus recommendation for neuropathologic diagnoses, because even these “diffuse” A β deposits signal that AD pathobiologic mechanisms are occurring. Further, the data were most compatible with the hypothesis that the APOE ɛ 4 allele exerts its effect(s) via driving A β deposition, i.e., an “upstream” influence, rather than being associated directly with A β– independent PART pathology.

Published: July 2018

The objective of the paper is to compare the level of corporate culture in Slovakia and Germany. Top managers of large transport companies were asked to participate in our research. Following the analysis, hierarchy corporate culture, with dominant features such as keeping within rules, regulations, was preferred in Slovak companies. Top Slovak managers asked for following this trend in the future. Clan corporate culture was the most used at present time as well as most preferred in following 5 years in Germany. Top German managers focused on employee's needs and employee's development. Our recommendation for top German managers is to remain in this trend. For top Slovak managers we propose to change their perception and to consider employees as a key factor. Employees are owners of new creative ideas through which enterprises can build their competitive advantage.

The miniature seasonal killifishSpectrolebiascostae, first described for the middle Araguaia River basin, has been also recorded from two areas in the middle Tocantins River basin, from where male specimens exhibit some differences in their colour pattern. Analyses directed to species delineation (GMYC and bPTP), using a fragment of the mitochondrial gene COI, strongly support two species,S.costaefrom the Araguaia River basin and a new species from the Tocantins River basin.Spectrolebiasgracilissp. n.is described on the basis of specimens collected from two localities separated by about 530 km, Canabrava River floodplains near Alvorada do Tocantins and Tocantins River floodplains near Palmeirante. Field inventories were unsuccessful in finding additional populations in the region, which is attributed to the high environmental degradation, including several large dams that have permanently inundated typical killifish habitats.Spectrolebiasgracilisis member of a clade also includingS.costae,S.inaequipinnatus, andS.semiocellatus, diagnosed by having the dorsal and anal fins in males with iridescent dots restricted to their basal portion, caudal fin in males hyaline, and caudal-fin base with two pairs of neuromasts. Within this clade, a single miniaturisation event is supported for the most recent common ancestor of the subclade comprisingS.costaeandS.gracilis, which differ from other congeners by reaching only about 20 mm standard length as maximum adult size.
Gout and the Risk of Incident Erectile Dysfunction: A Body Mass Index-matched Population-based Study
Authors: Schlesinger Naomi , Lu Na , Choi Hyon K.
Published: July 2018

Objective.

Gout is the most common inflammatory arthritis. Erectile dysfunction (ED) is common in the general population; however, evidence regarding ED among patients with gout is limited. Our purpose was to study the association between incident gout and the risk of incident ED in the general population.

Methods.

We conducted a cohort study using The Health Improvement Network, an electronic medical record database in the United Kingdom. Up to 5 individuals without gout were matched to each case of incident gout by age, enrollment time, and body mass index (BMI). Multivariate HR for ED were calculated after adjusting for smoking, alcohol consumption, comorbidities, and medication use.

Results.

We identified 2290 new cases of ED among 38,438 patients with gout (mean age 63.6 yrs) and 8447 cases among 154,332 individuals in the comparison cohort over a 5-year median followup (11.9 vs 10.5 per 1000 person-years, respectively). Univariate (matched for age, entry time, and BMI) and multivariate HR for ED among patients with gout were 1.13 (95% CI 1.08–1.19) and 1.15 (95% CI 1.09–1.21), respectively. In our sensitivity analysis, by restricting gout cases to those receiving anti-gout treatment (n = 27,718), the magnitude of relative risk was stronger than the primary analysis (multivariate HR 1.31, 95% CI 1.23–1.39).

Conclusion.

This population-based study suggests that gout is associated with an increased risk of developing ED, supporting a possible role for hyperuricemia and inflammation as independent risk factors for ED.

Objective.

Antibodies that recognize the phosphatidylserine/prothrombin complex (antiphosphatidylserine/prothrombin antibodies; aPS/PT) might reveal enhanced thrombotic risk in patients with systemic lupus erythematosus. Little is known about their association with pregnancy complications in the antiphospholipid syndrome (APS).

Methods.

We enrolled 55 patients with APS who were seeking pregnancy in 2 Italian hospitals. Antiphospholipid antibodies (aPL), including anticardiolipin antibodies, anti-β2-glycoprotein I antibodies, lupus-like anticoagulant, and aPS/PT antibodies were assessed, and the patients were prospectively followed for 24 months.

Results.

There were 65% (36/55) of the APS patients who had aPS/PT antibodies. Forty-seven pregnancies were followed, including 33 of aPS/PT+ patients. Forty-one of the 47 patients (87%) who initiated a pregnancy eventually gave birth to a child. The pregnancy duration and the mean newborn weight at delivery were significantly lower in aPS/PT+ than in aPS/PT− patients (33.1 ± 4.7 vs 36.2 ± 3.4 wks of gestation, respectively, and 2058 ± 964 g vs 2784 ± 746 g, respectively, p < 0.05). Late pregnancy complications, including intrauterine fetal death, preterm delivery, preeclampsia, and intrauterine growth restriction (IUGR), were more frequent in aPS/PT+ patients, independent of the therapy. Titers of aPS/PT IgG were significantly inversely correlated with the neonatal weight at delivery. Vascular injury, as reflected by thrombosis, fibrinoid necrosis, ischemic and hemorrhagic areas, and presence of chorangiomas characterized the IUGR placentas in the presence of aPS/PT.

Conclusion.

The aPS/PT antibodies might represent markers of aPL-related pregnancy complications, IUGR/preeclampsia in particular, and could help identify beforehand patients who may require additional treatment.
