Sammler*innen
Authors: Eybl Martin
Published: September 2022

Wien durchlief im Jahrhundert der Aufklärung eine dynamische soziale und wirtschaftliche Entwicklung. In einem rasant wachsenden Markt von Musikalien, Instrumenten und Musikunterricht wurde das Sammeln von Musik zusammen mit den zugehörigen geselligen Praktiken zu einem strategischen Mittel, den angestammten sozialen Rang zu behaupten oder einen neuen, höheren Rang zu gewinnen. Martin Eybl untersucht am Beispiel von Sammler*innen dieses sich neu etablierende Forum gesellschaftlicher Kommunikation über Musik. Er beleuchtet damit ein Feld der unausgesetzten Auseinandersetzung zwischen erster und zweiter Gesellschaft, zwischen Aristokratie und Bürgertum.
Historic Preservation as Change Management: Methods in Context
Authors: Scheurmann Ingrid
Published: September 2022

Ingrid Scheurmann discusses the significance of heritage preservation in high-density metropolises and analyses relevant historical theories and practices of conservation, repair and change management. She focuses on concepts like "Reparaturgesellschaft" (repair society, Wilfried Lipp 1993) and The Burra Charter (Icomos Australia, 1999) and their pleas for implementation of change mangement and participation processes within diverse urban contexts. The text highlights value-based questions and aspects of sustainability within the overall context of climate change and the need for transdiciplinary and transnational ideas for an understanding of preservation as a repair-, prevention- and modification-culture.

Interdiscourse Theory and the Analysis of Collective Symbols
Authors: Parr Rolf
Published: September 2022

Rolf Parr first outlines some basic premises of interdiscourse theory, which form the constitutive framework for the analysis of collective symbols. In a second step, he presents the system of collective symbols characteristic for Western Europe. It plays a major role in the perception of metropolises as well as in the images of metropolises communicated by the media and politics. Subsequently, a concrete example is discussed in order to illustrate the analysis of collective symbols and to illustrate the specific effectiveness of this analysis for metropolitan research. The chapter ends with some references to other concepts and Methods of metropolitan studies.
Urban Modelling: Quantitative and Qualitative Approaches
Authors: Gönsch Jochen , Gurr Jens Martin
Published: September 2022

Jochen Gönsch and Jens Martin Gurr focus on the role of models in understanding and managing urban complexity. A primer on quantitative models from the operations research community shows their advantages and disadvantages. By contrast, from the perspective of literary urban studies, texts are discussed as qualitative models, and a novel on spatial and temporal layers in the Ruhr region serves as a case study on modelling complexities in a literary text. Finally, the role of models in both approaches is compared. The essay thus highlights intersections, transfers and complementarities between quantitative and qualitative models.
Fan Fiction Genres
Authors: Goldmann Julia Elena
Published: September 2022

What if James T. Kirk and Spock had a baby, left the Enterprise and moved to New Vulcan to live happily ever after? Fan fiction plots like this are a strong testament of fans' endless creativity. Not only do the authors invent their own storylines but they have developed a generic definition of content across fandoms according to the relationship present in the text. Classification is therefore profoundly related to gender and sexuality. Julia Elena Goldmann examines these generic structures and formulaic patterns comparatively in Star Trek and Supernatural fan fiction. She also focuses on the interplay of the concepts of gender, sexuality, relationships and depictions of family in these texts.

»Raus aus dem Silodenken!« So lautet ein Bonmot zur besseren Steuerung öffentlicher Prozesse. Verwaltung, Politik, Wirtschaft, Wissenschaft und Zivilgesellschaft sind zu neuen Kooperationen aufgerufen. Doch wie lässt sich intersektorales Arbeiten fassbar machen? Für Stadt- und Raumplanung ist Storytelling dabei ein zentrales Steuerungsinstrument. Christian Horn betrachtet dazu in fünf Fallstudien Projekte der Internationalen Bauausstellung Thüringen und des Quartier de l'Innovation in Montréal. Aufbauend auf soziologischen, betriebswirtschaftlichen, literatur- und kulturwissenschaftlichen Ansätzen liefert er ein offenes Akteursmodell als Alternative zum klassischen Verwaltungshandeln.
Das Messianische
Authors: Rungelrath Hendrik
Published: September 2022

Die Begriffe des Messias und des Messianischen werden im Werk des italienischen Philosophen Giorgio Agamben in verschiedenste Zusammenhänge eingespannt. Wie kann eine theologische Rezeption seine Untersuchungen aufgreifen? Und kann sich Theologie grundlagentheoretisch von diesem Messianischen her verstehen? In einer systematischen Analyse des Gebrauchs des Begriffsregisters in Agambens Werk geht Hendrik Rungelrath den Verbindungen des messianischen Diskurses unter anderem zur Philosophie der Kunst, der Potenzialität oder der Sprache nach. Im Hinblick auf die performative Dimension des Messianischen legt er dabei Konturen einer messianisch bestimmten Theologie frei.

Penelitian ini mengeksplorasi kehidupan anak berkonflik dengan hukum (ABH/anak pelaku tindak kejahatan) pada aspek kehidupan mereka dari latar belakang ekonomi, lingkungan sosial, dan peer group dominasi maskulin. Studi ini menganalisis fokus kajian melalui elaborasi konsep penting dari Bourdieu, seperti habitus primer sekunder, doxa, heterodoxa, kapital, arena, dan dominasi maskulin. Studi kualitatif ini menggali data dari informan ABH dan beberapa petugas di LPKA Palembang. Pengumpulan Data melalui wawancara mendalam dan observasi. Sementara, analisis data secara interaktif melalui reduksi, display data, dan penarikan kesimpulan. Latar belakang ekonomi keluarga ABH sebagian besar berasal dari kelas sosial bawah dan lingkungan kurang mendukung dalam pengembangan karakter positif ABH. Posisi habitus primer ABH ini merupakan lingkungan negatif. Dalam hal ini, lingkungan sosial dan peer group menjadi referensi dalam proses pembentukan identitas sebagai habitus sekunder. Perilaku tindak kejahatan merupakan perwujudan heterodoxa ABH di luar arena mainstream (doxa). Lingkungan sosial dan peer group menjadi kapital sosial dan kapital budaya bagi ABH dalam arena kejahatan. Perspektif Bourdieu terkait gender pada masalah ini adalah konteks dominasi maskulin yang kuat. Hasil studi ini menunjukkan mayoritas ABH laki-laki. Sementara, perempuan dan anak perempuan lebih terlihat sebagai korban.

Artikel ini menelaah asal penciptaan perempuan dan mitos menstrual taboo, di mana merupakan akar historis pemahaman misoginis dalam Islam. Metode penelitian ini menggunakan kajian pustaka dengan pendekatan kajian tematik tafsif bi ar-ra’yi dalam perspektif gender dan analisis deskriptif-eksploratif. Hasil penelitian menunjukkan pemahaman tentang mitos-mitos di luar Islam pada era Jahiliyyah yang berpengaruh pada penafsiran ulama klasik yang terkesan misoginis terhadap perempuan. Kajian teks suci ini menunjukkan perempuan tidak diciptakan dari tulang rusuk bengkok. Hal ini melihat makna نفس (nafs) dalam berbagai konjugasi kata yang terulang 295 kali dalam al-Qur’an. Kata tersebut tidak hanya memiliki makna Adam secara spesifik, tetapi punya arti luas sebagai bangsa (ras). Sementara, mitos menstrual taboo memunculkan pemahaman menstrual creations. Hal ini dulu nampak tabu dan mendiskriditkan perempuan, berbeda dengan masa kini yang menjadikan bagian dari mode dan gaya hidup sehingga living ibadah sebagai bagian dari menstrual taboo.
[The article talks the creation of women and the menstrual taboo myth that is the misogynistic understanding in al-Qur’an and Hadis interpretation. The method uses a library document with a gender issue and descriptive-exploratory analysis on tafsir bi al-ra’yi. The paper finds the history of pre-Islamic myths era in taking effect for classical scholars on exegeses of Misogynist perspective. The study of exegeses for al-Qur’an and hadis is not talking about the creation women from a crooked rib. It puts the meaning of the word ‘نفس’ (nafs) in 295 various conjugations. The word is not in meaning man “Adam” on specifically but has a big meaning in people generally sex. Meanwhile, the menstrual taboo myth sees for living menstrual creation.

Goodluck Jonathan, The Champion of Women in the Contemporary Nigeria, 2010-2015: An Appraisal
Authors: Ibekwe Juliet Chinenye , Chidiobi Okechukwu Christian
Published: September 2022

The meteoric ascendency of Dr. Goodluck Ebele Jonathan to the office of the number one citizen of Nigeria is not just seen by many as providential but could be also termed as a journey of grace. The Goodluck Jonathan’s led administration spanned from 2010 to 2015. He was elected as the 7th democratic president of Nigeria in 2011 general/ Presidential election for a four year tenure which ended in 2015 and in which he failed the bid to be reelected. The administration of President Goodluck Jonathan was characterized or bedeviled by severe criticism, a development which contributed largely to his exit in 2015 after just a tenure in office. These criticisms were apparently predicated on a number of pertinent national issues which were economic, socio-political and even religious in nature. The worst being the inability of the government to combat the upsurge in Boko Haram menace, their failure to rescue the alleged abducted Chibok Girls as well as massive cases of corruption among top public office holders and the presumed laissez-faire attitude of the president in addressing the ugly development. In spite of these avalanche of criticisms however, one major area of interest in which the Jonathan’s administration was greatly commended even by the international community was on women empowerment. The administration was adjudged to have performed well above international average of 20%, and it is in view of this that the idea behind this paper is conceived, to appraise the effort of the president in enhancing the status of the Nigerian women. Jonathan appointed many women into positions of authorities and provided avenues by which a good number of them were elected into political offices. There was also empowerment programs such as skill acquisitions and micro-credit loan schemes meant to alleviate the sufferings of the ordinary women and put smiles on their faces. Although this administration could not realize the 5% affirmative action plan recommended as benchmark in Beijing, China in 1985, it is however good to know that about 33% of this well above international average was said to have been achieved. These and a few related issues were discoursed in this paper. Feminist theory was adopted as a theoretical framework to explain the gender based discrimination against women and therefore focuses on promotion of women’s rights and interests. In view of this, measures that could help to end this unhealthy practices and that can free women from the shackles of age-long domination of men were thus suggested.

Published: September 2022

The phenomenon of addiction to the use of social media on the Internet has become noticeably prevalent among young people and adolescents. Therefore, this study sought to find out whether there is a direct relationship between Internet addiction, psychological alienation, and emotional relationships, and whether there are statistically significant differences in (internet addiction, psychological alienation, emotional relationships) due to the economic level, and Whether there are statistically significant differences attributed to gender and educational qualification in both electronic communication addiction, emotional relationships, and psychological alienation, in addition to spreading awareness among families about the danger of excessive use of electronic means of communication on adolescents and youth and clarifying the psychological, social and behavioral problems resulting from it. The current study released on the descriptive survey method, and the study sample included (74) respondents from young people and adolescents of both sexes in the Makkah region. A questionnaire was developed to collect the data needed for this study by reviewing the relevant literature. The questionnaire consisted of two parts: the first section included demographic data for the sample members, namely gender, social status, educational level, economic level, and the number of hours of internet use per day. The second section included the next main themes of the study: The first axis: addiction to electronic media; the second axis: the impact of Internet addiction on the behavior of individuals (emotional behavior); the third axis: the impact of Internet addiction on the occurrence of psychological alienation among adolescents and young adults. Among the most important findings of the study is the existence of a direct relationship between the study variables (internet addiction, psychological alienation and emotional relationships), meaning that the greater the internet addiction, the greater the psychological alienation and emotional relationships, and vice versa. The study recommended holding training courses for parents on how to deal with children in light of the globalization of the Internet, providing oversight from a specialist to combat Internet products and markets, and providing control and control programs.
The Importance of Parent/Child Communications About Children’s Savings Accounts for Developing a College-Bound Identity
Authors: Zheng Haotian , Elliott William , O'Brien Megan
Published: September 2022

Children’s Savings Accounts (CSAs) not only can help children and families to pay for expenses related to postsecondary education but also produce positive social and psychological effects, such as children’s college-bound identity. In this sense, CSAs provide a rich context for parent and child to communicate about college and ultimately for children to co-construct a college-bound identity with parents. This study examines the relationship between parent/child communication about participation in CSA and children’s college-bound identity. Using data from 506 parent/child dyads participating in the Promise Scholars CSA, we examine if parent/child communications about their CSA are associated with a stronger college-bound identity, an important predictor of future academic success. Propensity score weighting is performed to minimize the impact of selection bias. Multiple imputations are performed to handle missing data. We find evidence of higher college-bound identity scores among communicator dyads compared to non-communicator dyads and the comparison group. We also find that the difference in college-bound identity scores is not statistically significant between non-communicator dyads and the comparison group. Given this finding, CSA programs may consider interventions that may facilitate parent/child communications about their CSA as a way of encouraging children to form a college-bound identity. Further, we posit that parent/child communications about CSA are another important way for programs to understand engagement as most programs aim to increase college attendance. Until recently, CSA programs have often narrowly understood engagement as whether families make contributions or not.

Negotiated Management as a Tool to Achieve Social Control over Political Protest and Social Movement Organizations
Authors: Lynn Tamara J.
Published: September 2022

Social movement scholars describe negotiated management as a process of collaboration between those in power and those in resistance.  For this research, content analysis and critical discourse analysis are used to evaluate questionnaire responses from law enforcement agencies in communities where competing grassroots political organizations engaged in political protest.  Findings indicate that law enforcement exercise different levels of social control toward those least likely to engage in, or submit to, a negotiated management model of policing. I argue that responses toward organizations, as reported in questionnaire responses, demonstrates a structural permanence of social control.  Negotiated management between the state and competing grassroots political organizations is a tool used to achieve informal control.  Organizations that fail – or choose not – to engage in informal social control of their members risk escalated force by police agencies that seek compliance.  Results of this research increase understanding of law enforcement responses to political protest groups.
Soicial Factors and Citizens' Perception of the Police
Authors: Pullin Mark
Published: September 2022

Research examining citizen perception of the police have typically looked at expanded views of how the police interact in the community. By narrowing the focus to encompass two principles that associate citizen satisfaction with and perceptions of the police, this paper will include areas that influence satisfaction directly from citizens toward police officers themselves. Moreover, recent research stresses the importance of police/citizen relationships for positive outcomes to occur after interaction.  Research regarding race and ethnicity of the citizen is reviewed as well as youth and age to provide context for this article. Demographic variables have been shown to have an impact of citizen perception of the police thus affecting how they view the police and government agencies. Police literature is reviewed as to how these demographics contribute to neighborhood level changes in attitudes toward police officers. Community policing literature and the effects it has on neighborhood social cohesion and collective efficacy is also included. This will lead into a discussion of neighborhood social cohesion and collective efficacy and their impact on citizen perceptions of the police.

Published: September 2022

Objectives

Hepatocellular carcinoma (HCC) is difficult to diagnose early and progresses rapidly, making it one of the most deadly malignancies worldwide. This study aimed to evaluate whether salivary glycopattern changes combined with machine learning algorithms could help in the accurate diagnosis of HCC.

Methods

Firstly, we detected the alteration of salivary glycopatterns by lectin microarrays in 118 saliva samples. Subsequently, we constructed diagnostic models for hepatic cirrhosis (HC) and HCC using three machine learning algorithms: Least Absolute Shrinkage and Selector Operation, Support Vector Machine (SVM), and Random Forest (RF). Finally, the performance of the diagnostic models was assessed in an independent validation cohort of 85 saliva samples by a series of evaluation metrics, including area under the receiver operator curve (AUC), accuracy, specificity, and sensitivity.

Results

We identified alterations in the expression levels of salivary glycopatterns in patients with HC and HCC. The results revealed that the glycopatterns recognized by 22 lectins showed significant differences in the saliva of HC and HCC patients and healthy volunteers. In addition, after Boruta feature selection, the best predictive performance was obtained with the RF algorithm for the construction of models for HC and HCC. The AUCs of the RF-HC model and RF-HCC model in the validation cohort were 0.857 (95% confidence interval [CI]: 0.780–0.935) and 0.886 (95% CI: 0.814–0.957), respectively.

Conclusions

Detecting alterations in salivary protein glycopatterns with lectin microarrays combined with machine learning algorithms could be an effective strategy for diagnosing HCC in the future.
Technical and health governance aspects of the External Quality Assessment Scheme for the SARS-CoV-2 molecular tests: institutional experience performed in all clinical laboratories of a Regional Health Service
Authors: Di Gaudio Francesca , Brunacci Giuseppina , Contino Flavia , Gallo Alessia , Centineo Fabio
Published: September 2022

Objectives

Since December 2019, the worldwide public health has been threatened by a severe acute respiratory syndrome caused by Coronavirus-2. From the beginning, a turning point has been the identification of new cases of infection, in order to minimize the virus spreading among the population. For this reason, it was necessary introducing a panel of tests able to identify positive cases, which became crucial for all countries.

Methods

As a Regional Reference Centre, the CRQ Laboratory (Regional Laboratory for the Quality Control) developed and conducted an External Quality Assessment (EQA) panel of assay, so as to evaluate the quality of real-time reverse transcription polymerase chain reaction (PCR), which were used by 62 Sicilian laboratories, previously authorized to issue certificates for the COVID-19 diagnosis, on behalf of the Public Health Service.

Results

The qualitative performance test was based on pooled samples with different viral loads of SARS-CoV-2 or human Coronavirus OC43. 75% of the participating laboratories tested all core samples correctly, while the remaining 25% interpreted incorrectly the EQA exercise samples matching negatively the standards required.

Conclusions

Subsequent inspection visits confirmed the issue of incorrect positive and negative certifications for COVID-19 by private and public laboratories, despite the possession of the authorization requirements currently provided for by current regulations, with a significant impact on the SSR.
Effect of pressurized hot water extraction and esterification on the moisture properties and decay resistance of Scots pine (Pinus sylvestris L.) sapwood
Authors: Kyyrö Suvi , Altgen Michael , Belt Tiina , Seppäläinen Hanna , Brischke Christian , Heinze Petra , Militz Holger , Rautkari Lauri
Published: September 2022

Pressurized hot water extraction (HWE) treatment has the benefit of simultaneous extraction of hemicellulose-based carbohydrates and modification of the solid phase, but it does not drastically improve wood durability. However, removing hemicelluloses from the wood by HWE treatment creates water-filled spaces in the cell walls which could be filled with modification agent in order to improve the properties of the wood. Without drying, modification agent can be added into the saturated wood via diffusion. The esterification of wood with citric acid (CA) improves resistance to biological deterioration but increases brittleness. However, combining CA esterification with additional chemicals that form links with CA can mitigate brittleness. This study investigated esterification as a method for modifying HWE treated wood. HWE treatment with CA solution (4% w/v) was applied at 120 °C for 3 h to Scots pine (Pinus sylvestris L.) sapwood specimens. The specimens were further modified by diffusion with CA and starch derivatives followed by curing. The applied method changed the moisture properties and chemical composition of the wood. The results showed successful wood bulking. The investigated method slightly improved decay resistance to Coniophora puteana and Trametes versicolor but did not change resistance to Rhodonia placenta.
Effect of substrate temperature on structural, optical, and photoelectrochemical properties of Tl2S thin films fabricated using AACVD technique
Authors: Daraz Umar , Ansari Tariq Mahmood , Arain Shafique Ahmad , Mansoor Muhammad Adil , Mazhar Muhammad
Published: September 2022

Thin films of thallium sulphide (Tl2S) were grown on the FTO surface at three different temperatures (500°C, 550°C, and 600°C) using the aerosol-assisted chemical vapor deposition approach. A thallium diethyldithiocarbamate (Tl[CNS2(C2H5)3]) complex was used as a single-source precursor in tetrahydrofuran (THF) solvent under an inert atmosphere of argon in all deposition experiments. The impact of deposition temperature on structural, morphological, and optical properties of Tl2S thin films was explored using different experimental techniques such as X-ray diffraction (XRD), field-emission scanning electron (FESEM) microscopy, and UV-visible spectrophotometry. XRD analysis specifies that crystallite size varies from 120 to 90 nm with the increase in temperature from 500°C to 600°C. FESEM results revealed that Tl2S films were grown as hexagonal, petals, and marigold flower-like particles at 500°C, 550°C, and 600°C, respectively. UV-visible spectrophotometric analysis shows a decrease in band gap energies with temperature: 1.92 eV at 500°C, 1.72 eV at 550°C, and 1.42 eV at 600°C. The photoelectrochemical measurement in terms of linear sweep voltammetry confirms that the temperature variation has a significant effect on the photoconversion efficiency of Tl2S thin films, and photocurrent density increases from 0.56 to 0.76 mA·cm−2 when the temperature is increased from 500°C to 600°C.

Published: September 2022

Optical vortices carrying orbital angular momentum (OAM) have recently attracted increasing interest for providing an additional degree of freedom for capacity scaling in optical communications. The optical vortex generator is an essential component to facilitate OAM-enabled optical communications. Traditional devices face challenges of limited compactness, narrow bandwidth, and first-order OAM modes. Here, using the direct-binary search (DBS) optimization algorithm, we design, fabricate, and demonstrate a digitized subwavelength surface structure on silicon platform for the generation of wavelength-/polarization-/charge-diverse optical vortices. It features an ultra-compact footprint (∼3.6 × 3.6 μm2) and ultra-wide bandwidth (1480–1630 nm), supporting two polarizations (x-pol., y-pol.) and high-order OAM modes (OAM+1, OAM−1, OAM+2, OAM−2) with high purity of larger than 84%. The mode crosstalk matrix is measured in the experiment with favorable performance. When generating x-pol. OAM+1, x-pol. OAM−1, y-pol. OAM+1, and y-pol. OAM−1 mode, the crosstalk of the worst case is less than −14 dB. When generating OAM+1, OAM−1, OAM+2, and OAM−2 mode, the crosstalk between any two OAM modes is less than −10 dB, and the lowest crosstalk is about −17 dB. In addition, we also show the possibility for generating much higher-order OAM modes (e.g. OAM+3, OAM−3, OAM+4, and OAM−4) with the digitized subwavelength surface structure. The wavelength-/polarization-/charge-diverse optical vortex generator enables the full access of multiple physical dimensions (wavelength, polarization, space) of lightwaves. The demonstrations may open up new perspectives for chip-scale solutions to multi-dimensional multiplexing optical communications.

This study was performed on 200 routinely laboratory sent BFs. Cell counts and differentiation were determined with both bright-lined Neubauer Cell Counting Chamber and Sysmex XN-1000 system body fluid mode.

Results

The correlation coefficients of WBC count by two methods indicated very strong correlation (r≥0.90, p<0.0001) for any specimen except pleural fluid. According to Passing-Bablok regression analysis, Sysmex XN-1000 showed acceptable performance according to bias of the slope criteria (<±20%).

Conclusions

The XN-1000 hematological analyzer’s body fluid mode can rapidly count and identify cells, and it can be used as a simple and rapid screening method for laboratory testing of sterile body fluids, particularly in laboratories with a massive quantity of biological fluids.
Reactivity Evaluation of Harvested Class C Fly Ash
Authors: Alaibani Anfal , Riding Kyle A.
Published: September 2022

Unused Class C fly ash has been disposed of in large impoundments or landfills for many decades. Reclamation and use of this material in concrete could provide a solution to environmental challenges and alleviate shortages of fresh fly ash in some locations. This research study investigated beneficiation and the use of harvested Class C fly ash as a supplementary cementitious material (SCM) at different replacement percentages of portland cement. The reactivities of three different sources of harvested Class C fly ash were evaluated with different amounts of grinding at low and high temperature curing. Isothermal calorimetry, the R3 method, strength activity index, the modified lime-pozzolan strength test, thermogravimetric analysis, and quantitative x-ray diffraction were used to analyze the physicochemical, mineralogical, and hydration kinetics properties of the harvested ashes. While harvested Class C fly ash showed great potential for use in concrete as an SCM, limits on loss on ignition may be helpful in limiting the calcium carbonate content and giving good performance at temperatures higher than laboratory temperatures.
Physical Modeling of Coupled Thermohydraulic Behavior of Compacted MX80 Bentonite during Heating
Authors: Lu Yu , McCartney John Scott
Published: September 2022

This paper describes a tank-scale test setup and experimental methodology used to investigate coupled heat transfer and water flow processes during heating of compacted MX80 bentonite to high temperatures. Specifically, a temperature of 200°C was maintained by a cylindrical heating element at the center of a compacted bentonite layer containing an array of temperature, dielectric, and relative humidity sensors. In addition to providing an evaluation of the spatiotemporal variations in temperature, relative humidity, degree of saturation, and global volume, the coupled thermohydraulic properties of the bentonite were assessed. A wetting front was initially observed to move away from the central heater, followed by a drying process until reaching thermohydraulic equilibrium. The soil–water retention curve (SWRC) of the bentonite followed a wetting scanning path before following the primary drying path exhibiting a shift in water retention with elevated temperature. Results from the tank-scale test can be used for validation of numerical simulations of drying processes in the engineered barrier system of a high-level radioactive waste geological disposal repository and confirm that a temperature-dependent hysteretic SWRC with scanning paths is required to accurately capture the bentonite response.

Di era big data saat ini, peran teknik data mining sangatlah dibutuhkan terkait kebutuhan pengambilan keputusan yang akurat. Algoritma decision tree telah lazim diterapkan untuk menemukan pola klasifikasi karena mudah diinterpretasikan namun harus senantiasa dievaluasi tingkat performanya. Adaboost merupakan salah satu metode untuk meningkatkan performa algoritma decision tree. Eksperimen dilakukan pada 141 sampel perusahaan yang melantai di Bursa Efek Indonesia sektor konstruksi-infrastruktur, pertambangan-perminyakan, dan sektor perbankan pada periode 2019, dengan menerapkan teknik adaboost pada decision tree dengan parameter maximum depth dan confidence yang diuji dalam enam skenario berbeda berdasarkan informasi anti-korupsi pada pengungkapan laporan tahunan perusahaan. Hasil ekperimen decision tree untuk akurasi sebesar 69,5%, AUC-optimistis 0,826, dan AUC 0,756, sedangkan rerata hasil dari enam skenario decision tree versi  adaBoost untuk akurasi sebesar 71,16%, AUC-optimistis 0,8905, dan AUC 0,744, sehingga dapat disimpulkan bahwa pengklasifikasian atas prediksi klasifikasi dengan metode adaBoost layak diterapkan sebagai upaya alternatif untuk meningkatkan tingkat performa yang lebih baik.

Badan Pusat Statistik (BPS) berperan dalam memberikan pelayanan publik untuk penyediaan data dan informasi statistik, salah satunya melalui website BPS. Kepuasan pengguna website merupakan salah satu tolak ukur dari keberhasilan penyelenggaraan pelayanan publik tersebut. Penelitian ini bertujuan untuk memperoleh gambaran persepsi, masukan, serta harapan masyarakat terhadap website BPS melalui Survei Kepuasan Pengguna Website. Data yang diperoleh dari survei tersebut dianalisis dengan menggunakan metode Customer Satisfaction Index (CSI) dan Importance and Performance Analysis (IPA). Hasil dari penelitian adalah taraf kepuasan pengunjung website BPS memiliki angka persentase sebesar 78,68%, yang termasuk kategori “Puas” dalam kriteria CSI. Namun, pada masing-masing aspek, masih terdapat gap negatif antara tingkat kepentingan dan kepuasan pengguna website. Oleh karena itu, untuk menentukan skala prioritas dalam usaha perbaikan website, digunakan metode Importance and Performance Analysis (IPA). Hasil analisis IPA menunjukkan bahwa masih terdapat lima aspek yang perlu ditingkatkan dan menjadi prioritas utama perbaikan website, yaitu: kelengkapan metadata, kesesuaian produk, kemudahan navigasi, kemudahan pencarian produk, dan kehandalan fungsi pencarian. Sementara itu, terdapat empat aspek yang sudah baik dan perlu dipertahankan yaitu: kemutakhiran produk, kemudahan memperoleh produk, ketepatan jadwal rilis dan kemudahan mengunduh produk.

Bu araştırmanın amacı, Diyarbakır ili Merkez dört ilçelerinden olan (Bağlar, Kayapınar, Sur, Yenişehir) görev yapan öğretmenlerin, sendikalara ilişkin öğretmenlerin görüş ve beklentilerini belirlemektir. Araştırma, nitel araştırma yöntemlerinden durum çalışmasıyla desenlenmiştir. Araştırmaya toplamda 21 öğretmen katılmıştır. Araştırmaya katılanlardan 14’ü bir sendika üyesi, 7’si ise herhangi bir sendika üyesi olmayan öğretmenlerden oluşmaktadır. Araştırmada veriler görüşme yolu ile elde edilmiştir. Yapılan araştırma sonucunda, öğretmenlerin sendikalara üye olmasında en önemli faktörlerin örgütlü olma durumu ve özlük haklarının korunması olduğu tespit edilmiştir. Öğretmenlerin sendikal örgütlenmeye olumsuz bakmalarında sendikaların siyaset kurumu ile olan ilişkisinin etkili olduğu ve "sendikaya üye olursam başıma neler gelir korku ve endişesinin" olduğu tespit edilmiştir. Öğretmenlerin sendikalara ilişkin olumlu görüşü arasında, sendikaların örgütsel bir yaşamın parçası olarak görüldüğü yer alırken olumsuz görüşü arasında ise sendikalar ile siyaset kurumu arasındaki ilişkinin varlığı yer almıştır. Öğretmenlerin sendikalardan en önemli beklentileri ise; sendikaların özlük haklarının korunması ve geliştirilmesi için yaptıkları çalışmaların arttırılması, sendikaların siyasi partilerin temsilcisi gibi siyaset yapmamaları gerekliliği vurgulamıştır.
