The Impact of Maternal BMI on Time of Transvaginal Cervical Imaging
Authors: Azeem Nabila , Starnes Victoria , Chen Katherine , El-Sharaiha Rand , Russell Kirsten , Van Hook James , Khurshid Nauman
Published: July 2024

Introduction: Ultrasound is an integral part of obstetrical care and obesity has been shown to decrease the accuracy of ultrasound examination in high-risk pregnancy (Tsai et al, 2015). Obesity decreases the fidelity of ultrasound, as decreased visualization is seen with increasing depth of abdominal adipose tissue (Paladini, 2009). While maternal obesity has been shown to detrimentally impact anatomical ultrasound, the effects of obesity on the performance of transvaginal ultrasound are unclear. Our aim was to evaluate if obesity has an effect on the time required to obtain transvaginal cervical length.

Methods: Retrospective chart review between January 2016-January 2022 identified patients with cervical shortening (<2.5 cm) at the time of mid-trimester anatomical ultrasound scans. Scans were performed at the Maternal Fetal Medicine Department at Promedica Toledo Hospital between 16- and 24-weeks gestation. Patient BMI was recorded at the time of ultrasound and divided into obese (BMI ≥ 30 kg/m²) and non-obese (BMI ≤ 30 kg/m²) categories. Time to complete transvaginal ultrasound imaging was recorded in both patient populations and compared.

Results: 216 patients met study criteria. Out of the 216, 89 (41%) were obese and 127 (59%) were non-obese. Average BMI of all participants was 29.2 ± 7.4 kg/m². Average time spent on ultrasound for patients with BMI <30 was 13:36 ± 01:28 and for BMI >30 15:34 ± 01:48 (p=0.46). There was no statistical difference between obese and non-obese patients and transvaginal scanning time > 10 minutes (OR 1.24, 95% CI 0.719-2.13, p=0.44)

Discussion: Our results suggest that the time to obtain cervical length measurements via transvaginal ultrasounds is similar between obese and non-obese patients. Time necessary to perform endovaginal ultrasonography of the cervix does not appear to be affected by maternal BMI. Since length of time necessary to complete transvaginal cervical length measurement does not appear to be affected by maternal BMI, our results suggest that additional scheduling time does not need to be allocated for obese patients. Other investigators have shown that early incorporation of transvaginal assessment of fetal anatomy in obese women improved the rate of survey completion and demonstrated earlier completion of the fetal anatomic evaluation (Toscano et al, 2021). This study encourages the further use of transvaginal ultrasound in obese, obstetrical patients.
CVD Case Series: Screening and Risk Reduction
Authors: Woldemichael Ruth , Graves Cornelia R. , Hameed Afshan
Published: July 2024

Undetected cardiovascular disease is one of the leading causes of complications during pregnancy in the United States. Maternal mortality reviews indicate that lack of suspicion and delays in diagnosis are the primary drivers of CVD-related mortality. Purpose of this study is to examine the effect of implementing the CVD (Cardiovascular Disease) Risk Assessment tool developed by the California Maternal Quality Care Collaborative (CMQCC) team in 2018.

Eligibility of patients in the case series was determined through CVD risk screen score of 4 or higher using a standardized stool adopted from the CMQCC. The patient was scored at the point of hospital entry. Factors used in scoring included symptoms, vitals and risk factors. Patients who scored positive were sent for further work up. This included in-depth analysis of other significant clinical factors influencing patient presentation and subsequent management.

The CV patient cases presented in this case series illustrate the benefits of early identification and implementation of standardized CVD risk assessment. There are significant benefits in early use of the CV screening tool contributing to mortality risk reduction including continued close antenatal surveillance, postpartum follow-up, and continued collaborative multidisciplinary care.

Patients with risk factors underwent continued surveillance and received appropriate specialized follow-up that allowed for improved maternal outcomes.

Proper implementation of CVD risk assessment tool for patients who are at-risk of development of CVD in pregnancy can effectively reduce adverse maternal outcomes related to cardiac disease.

Authors: Mariam Elahjal
Published: July 2024

Celiac disease (CD) is a popular autoimmune disorder induced by gluten-containing foods and other environmental, and genetic factors. Every individual's red blood cell expresses over two million ABO blood-type antigens. Furthermore, the stomach and small intestine are major expression sites for the ABH antigens. This study was intended to assess the distribution of ABO and Rh blood types in Libyan patients with celiac disease as well as compare between CD and healthy control groups regarding complete blood count parameters. Samples from 250 CD patients and 45 healthy control groups represented by 80 males (27.1%) and 215 females (72.9%) were enrolled in the study. The samples of CD were collected from patients who attended the gastroenterology outpatient clinic at Tripoli University Hospital (TUH) for follow-up. Two hundred and fifty blood samples were serologically screened for ABO, and Rh antigens using a tube agglutination test. Another group of healthy subjects (n = 45) and CD patients (n = 45) were analyzed for CBC test. The findings showed that the most observed ABO blood group among celiac patients was blood group O 129 (51.6%), followed by blood group A 80 (32%), and Rh-positive 222 (88.8%). Furthermore, the heritable proportion was 33%, with 21% classified as first-degree and 12% as second-degree hereditary. Additionally, the result of the independent Sample (T) test to compare RBCs, HGB, HCT, and NUT levels in blood between CD patients and healthy control showed that there were significant differences in the RBCs, HGB, and HCT counts with p-value = 0.034, <0.001, and <0.001 respectively. In contrast, Mann-Whitney U test results revealed significant differences in the PLT, MCV, MCH, and MCHC counts with p-value = <0.001, and for LYM with p-value = 0.003. Future studies on these simple inflammatory markers can guide us in predicting the diagnosis and prognosis.

Key Factors Affecting the Success of Construction Multi Project Management
Authors: Budiman Arief , Wiguna I Putu Artama
Published: July 2024

Simultaneous management of multiple projects has become a trend in the field of energy, oil and gas construction project management over the past decade. This situation is driven by the high market demand and need for fossil fuels, which also stresses project management discipline to improve its performance and efficiency in managing multiple projects simultaneously. Nevertheless, concurrent execution of multiple construction projects often leads to stretched the project durations and cost due to suboptimal resource management, which may become a boomerang and increase project costs. The objective of this study is to identify factors and indicators that contribute to the successful management of multiple projects. Although multi-project management has been extensively studied, there is still a dearth of studies analyzing the elements that make construction multi-project management successful, particularly in the energy, oil, and gas sectors. This research is a case study of an EPCIC company that uses multi-project management and operates in the oil and gas sector. Through purposive sampling techniques, a total of 58 executives from national oil and gas contractors with significant work experience participated in this study through a questionnaire survey. The PLS-SEM approach has revealed that the positive predictor factors influencing the success/performance of multi-project management are resource allocation, teamwork quality, multi-project management competency, and project manager assignment. Flexible and intelligent resource allocation management in multi-project cycles affected by uncertainty is a critical factor.

Authors: Din Cari , MacInnis Martin
Published: July 2024

As part of a large exercise physiology laboratory (lab) reform project, we used blended learning to support graduate teaching assistants and lab technicians in developing their pedagogical knowledge and create an entry point to reflective conversations about teaching and learning. Because self-paced asynchronous online modules can enable reflective and self-determined learning, this asynchronous professional development course is punctuated with reflective questions for the instructional team preparing to teach reformed exercise physiology labs. Asynchronous course content was shared via short videos, podcasts, and readings. We debriefed this self-paced, SoTL-informed course together, in-person. This social debriefing kicked off our weekly synchronous reflective conversations about teaching and learning in a community of practice. Developing a shared language for talking about teaching, enabling student learning, practicing effective teaching, and beginning to contemplate teaching philosophies were described by graduate teaching assistants as notable aspects of this blended learning journey. Lab technicians described discovering SoTL and discussing learning challenges as helpful to their teaching.

Published: July 2024

Responses to the transition to online learning during the pandemic underscores the importance of faculty engagement in professional development (PD) to enhance their teaching practices. However, the creation and offering of PD opportunities does not always lead to faculty engagement. Using a change management perspective (the ADKAR framework), this paper examines the facilitators and barriers to instructor engagement in a self-paced, online PD program addressing instructional skills for managing students’ experiences of test anxiety in the classroom. Seven university faculty members participated in focus groups to share their experiences of a pilot PD program in the program. The focus group data were deductively analyzed using the ADKAR framework. Key themes were identified, corresponding to the outcomes of ADKAR: awareness, desire, knowledge, ability, and reinforcements. Findings emphasized the value of considering PD as a change project, while also recognizing staff well-being as a significant factor that impacts engagement with the change process.

Object Registration Techniques For 3D Particle Tracking
Authors: Hendriksen Luuk Antonie , Sciacchitano Andrea , Scarano Fulvio
Published: July 2024

Image based 3D particle tracking is currently the most widely used technique for volumetric velocity measurements. Inspecting the flow-field around an object is however, hampered by the latter, obstructing the view across it. In this study, the problem of measurement limitations due to the above is addressed. The present work builds upon the recent proposal from Wieneke and Rockstroh (2024), whereby the information of the occluded lines of sight can be incorporated into the particle tracking algorithm. The approach, however, necessitates of methods that accurately evaluate the shape and position of the object within the measurement domain. Methods of object marking and the following 3D registration of a digital object model (CAD) are discussed. For the latter, the Iterative Closest Point (ICP) registration algorithm is adopted. The accuracy of object registration is evaluated by means of experiments, where marking approaches that include physical and optically projected markers are discussed and compared. Three objects with growing level of geometrical complexity are considered: a cube, a truncated wing and a scaled model of a sport cyclist. The registered CAD representations of the physical objects are included in aerodynamic experiments, and the flow field is measured by means of large-scale particle tracking using helium filled soap bubbles. Three operating regimes are studied and compared: monolithic, partitioned and object-aware (OA) monolithic. The results indicate that object registration enables a correct reconstruction of particle tracers and strongly reduces the domain clipping typical of the monolithic approach. Furthermore, the dynamical use of all views in the OA monolithic method offers clear benefits compared to the partitioned approach, namely a lower occurrence of ghost particles. Finally, the combined visualization of the object and the surrounding flow pattern offers means of insightful data inspection and interpretation, along with posing a basis for PIV data assimilation at the fluid-solid interface.
Data-Driven Diagnosis Of Measurement Biases For Filtered Rayleigh Scattering
Authors: Warner Evan , Byun Gwibo , Lowe Todd
Published: July 2024

This work focuses on the data mining of a filtered Rayleigh scattering (FRS) database to diagnose the source(s) of measurement biases experienced in these applied measurements in harsh environments. Qualitative statistical analysis is performed to assess modeled-to-measured signal disagreements. This qualitative analysis shows that the signal model converges to measured signals as the non-dimensional thermodynamic parameter, termed the Y-parameter for Rayleigh scattering analysis, decreases. To perform a quantitative assessment, these FRS datasets were processed for Y-parameter and compared to known values derived from reference measurements of the corresponding flow fields. Residuals between the FRS results and the reference values were plotted as a histogram, which showed that there is a region of "least-bias" corresponding to Y-parameter less than 1. Root cause assessment of bias sources suggests that the key contributing factor is uncertainty in the modeled Rayleigh-Brillouin scattering signal for air when Y-parameter is greater than 1.
Automatic Setup And Calibration Of A Robotic-PIV System Using Fiducial Markers
Authors: Michaux Frank , Brunn André , Willert Christian , Kallweit Stephan
Published: July 2024

The use of industrial robots allows the precise manipulation of all components necessary for setting up a large-scale particle image velocimetry (PIV) system. The known internal calibration matrix of the cameras in combination with the actual pose of the industrial robots and the calculated transform from the fiducial markers to camera coordinates allow the precise positioning of the individual PIV components according to the measurement demands. In addition, the complete calibration procedure for generating the external camera matrix and the mapping functions for e.g. dewarping the stereo images can be automatically determined without further user interaction and thus the degree of automation can be extended to nearly 100%. This increased degree of automation expands the applications range of PIV systems, in particular for measurement tasks with severe time constraints.
Low Volume Gas-Flow Seeding For Highly Resolved Velocimetry Of The Boundary Layer
Authors: Möller Christoph , Geschwindner Christopher , Dreizler Andreas
Published: July 2024

Ensuring fire safety in polymeric materials, which are inherently flammable but widely used in various industries, is of
significant societal and economic importance. This study is part of a broader effort to understand polymer combustion
and flame retardant effectiveness at a fundamental level. A major focus is the behavior of polymers burning along a
vertical wall, a configuration chosen to study the release of flammable gases during pyrolysis, which contributes to
the self-sustaining combustion reaction of a fire. This process occurs predominantly near the polymer surface within
the boundary layer, requiring detailed analysis to evaluate flame retardant effectiveness. Our experimental setup
replicates polymer pyrolysis using a flame-wall interaction burner with a vertical jet and a small inlet to mimic the
release of flammable gases. The primary challenge in this setup is the introduction of seeding particles for Particle
Image Velocimetry (PIV) measurements at low volume flow rates, which is complicated by reflections from the wall
and the small flow scale relative to the main flow. To address this problem, we have developed a novel piezo-based
ultrasonic seeder capable of controlled seeding at extremely low flow rates, thereby improving the accuracy of PIV
measurements in non-reactive configurations. This seeder uses a piezo ring to excite a perforated metal membrane,
forming uniform aerosol droplets. The design ensures a steady supply of particles, which is critical for evaluating
boundary layer conditions. Our results demonstrate the seeder’s ability to maintain sufficient seeding density in the
low volume flow region, facilitating detailed velocimetry analysis. The innovative seeder design proves effective in
overcoming the limitations of conventional methods and provides new insights into polymer combustion processes
and the role of flame retardants.
Validating Volumetric Measurements Using Helium-Filled Soap Bubbles in a Turbulent Boundary Layer And Wake Of An Axisymmetric Body Of Revolution
Authors: Manovski Peter , Loveday Dominic , Paul Deepthi , Silva Charitha De , Giacobello Matteo , Hutchins Nicholas , Marusic Ivan
Published: July 2024

This study focuses on the validation of a volumetric measurement technique to characterize the turbulent boundary layers (TBL) and wake of a slender axisymmetric body. Specifically, Lagrangian Particle Tracking (LPT) was employed to analyse a TBL subjected to an adverse pressure gradient (APG) and transverse curvature at the tail of an axisymmetric body, with a Reynolds number based on model length of 3.95×10 6 . For the LPT method, a seeding rake with 100 nozzles was used to disperse helium-filled soap bubbles (HFSB), which served as tracers. These tracers were illuminated by high-powered LED arrays, allowing their motion to be captured by three high-speed cameras at acquisition rates up to 20 kHz. A key aspect of this research was using shadowgraphy to measure the diameter of the bubbles exiting the nozzles and obtaining their statistical variations across the various nozzles in the seeding rake. The study identified that the diameter of bubbles averaged 0.45 mm, indicating a state of near-neutral buoyancy. The LPT results were then obtained using the shake-the-box (STB) tracking alogirthm, while ensemble bin-averaging of the scattered particle tracks was used to obtain turbulence statistics on a regular grid. To validate the LPT results, comparisons were made with time-resolved 2D Particle Image Velocimetry (TR-PIV) and highly resolved hot-wire anemometry. This comparative analysis revealed good agreement of the mean profiles across the methodologies, highlighting the robustness and accuracy of the LPT technique. While the turbulence levels in the outer layer were well captured by the LPT, some discrepancies were observed near the wall in both PIV and LPT data, indicating limitations in capturing small-scale phenomena. The implications of these findings, particularly in understanding the complex 3D flow effects of such TBLs and the resulting wake flow field are discussed.
Turbulent Channel Flow Diagnostics By Means Of Shake-The-Box (STB): Flow Structures And Sublayer Profiles
Authors: Kriegseis Jochen , Leister Robin , Rockstroh Thomas , Beslac Radomir , Frohnapfel Bettina
Published: July 2024

Time-resolved Shake-the-Box (STB) experiments have been conducted in the channel-flow facility at the Institute of Fluid Mechanics (ISTM) at f = 30 kHz repetition rate to study the near-wall velocity field at a viscous Reynolds number of Reτ = 350 (centerline velocity Ucl = 8.4 m/s, channel half-height h = 12.6 mm, viscous unit δv ≈ 36 μm) to testify the STB method for the applicability to provide high-resolution velocity information of the given flow field including the sublayer region of the channel flow. In addition to the extraction of Lagrangian particle tracks and corresponding Eulerian iso-surfaces of vortical structure the major emphasis of the study centers around an evaluation of the resulting near wall velocity profile. Particularly, it is discussed how the choice of data-processing steps and strategies affects the resulting velocity estimates in the immediate vicinity of the wall, where the major impact for the current study has been identified to result from image-arithmetic efforts during data pre-processing. The achieved results are discussed and further compared with direct numerical simulations (DNS) of similar Reτ and earlier experimental efforts at ISTM of the same flow configuration by means of stereoscopic particle image velocimetry (stereo PIV) and a laser-Doppler velocimetry profile sensor (LDV-PS). Finally, future perspectives of the experimental efforts for near-wall shear flow measurements are outlined on the grounds of the achieved insights.
Near-Wall Flow Features In ZPG-TBL At Various Reynolds Numbers Using Dense 3D Lagrangian Particle Tracking
Authors: Schröder Andreas , Schanz Daniel , Geisler Reinhard , Godbersen Phlipp , Agocs Janos , Simhan Abhijna R.
Published: July 2024

The 3D Lagrangian particle tracking method Shake-The-Box (STB) and, subsequently, the data assimilation method FlowFit3 have been applied to measure the flow field in a narrow wall-parallel volume inside the nearwall region of a zero-pressure-gradient (ZPG) turbulent boundary layer (TBL) flow at various Reynolds numbers. The STB experiments have been conducted in the 1m- wind tunnel facility of DLR in Göttingen at relatively high particle image densities (~0.07 ppp) using µm-sized DEHS particles and high-repetition pulse laser at up to 38.1 kHz. The results show that the chosen methodology is able to volumetrically resolve almost all features of the flow inside the viscous sub-, buffer- and lower logarithmic- layer in space and time at Reynolds numbers up to Re θ = 5,455. The gained data consists of time-series of spatially well resolved 3D velocity, acceleration and pressure fields, as well as a huge amount of long Lagrangian particle trajectories. Selecting the viscous sublayer part of the measurement volume provides time-series of the 2D distribution of both components of the instantaneous wall-shear stresses w,x/z . The resulting data are used for conditional and time-resolved 3D analyses of coherent structures, rare (e.g. back flow) events and two-point space-timecorrelations.
Towards High-Speed And High-Resolution Real-Time Optical Flow Particle Image Velocimetry
Authors: Pimienta Juan , Aider Jean-Luc
Published: July 2024

One of the major advantages of Optical Flow PIV (Particle Image Velocimetry) algorithms over Cross-Correlation PIV is their scalability leading to potentially very high computational speeds. This is confirmed in this study using different GPUs (Graphics Processor Unit) and different image sizes. The other advantage is the possibility of obtaining dense velocity fields of up to one vector per pixel. It is well known that particle seeding plays a crucial role in the results of standard particle image velocimetry based on cross-correlation algorithms. Its influence on the quality of the optical flow algorithm is not as well established. In this article the influence of particle concentration is quantified by introducing a criterion considering the proportion of “active” pixels in a snapshot. It is shown that it is possible to optimize particle concentration to maximize the percentage of active pixels, leading to better spatial resolution, down to one vector per pixel. The principle is validated on a vortex-free flow and applied to the complex 3D flow downstream a backward-facing step.
In-line PIV Using a Schlieren System
Authors: Raffel Markus , Heintz Alexander , Braukmann Johannes N. , Wolf C. Christian , Heineck James T.
Published: July 2024

"The article describes recent tests and developments of PIV recording and evaluation techniques that take advantage of strong forward scattering of tracer particles by in-line recording set ups. By collimating the light of a low-power light source between a pair of schlieren mirrors the observation area is increased to more than 350 mm. The same setup allows for schlieren recording of density gradients. The in-line imaging arrangements have a relatively high background intensity level on which brighter particle images can be detected. Ideally this background is constant in time such that it can be removed through subtraction.
The use of forward scattering has a significant influence on the required pulse energy of the light source used. Typically, sufficient illumination is achieved with about 1% of the pulse energy that would normally be used for a conventional orthogonal PIV arrangement employing a laser light sheet.

Re-Generation: The Missional Imperative of Christian Schooling
Authors: Pearce Cameron , Prior Chris
Published: July 2024

We live in a time where the Christian church and our Christian faith have been pushed to society's peripherals. Operating in environments that are increasingly secular, where consumerism abounds, it can be easy to define Christian schooling in almost oppositional terms. There is another way. What if those of us involved in Christian schooling were to reimagine Christian education through a shared missional lens grounded in the foundation of the Missio Dei (God's Mission)? The potential of the missional lens for Christian schooling is considerable. It grounds the Christian school movement, and the identity of the teacher, in the larger biblical narrative. Additionally, with each generation invited to engage in mission in a way that is contextual, it allows for a multiplicity of ways to participate in the outworking of God's mission within the context and setting in which each school has been placed.
Improving Financial Policy Compliance and Internal Control at Adventist Schools in Thailand: Recommendations from Stakeholders
Authors: Chulkasate Catherine , Hamra Wayne
Published: July 2024

This research study examined concerns about financial policy compliance and internal control mentioned in General Conference Auditing Service audit reports at four Seventh-day Adventist schools in Thailand. It focused on how to resolve recurring violations of denominational financial policies and improve control of accounting and administrative functions. A total of 32 in-depth interviews of external and internal stakeholders were conducted to search for practical ways to deal with common compliance and internal control problems. A key finding was a need to share policy compliance and management letters with school boards and financial staff, respectively, to facilitate rapid resolution of problems. Local contexts should be considered when implementing policies and internal controls. Given significant variations in laws and customs, higher organizations should study how to thoughtfully apply good governance principles in local situations.

The procurement of inoculum for bioassays with target spot, a significant disease in cotton and soybeans, caused by Corynespora cassiicola can be hindered by the low production of conidia on artificial culture media. The study aimed to determine whether mechanical stress on the mycelium and exposure to ultraviolet-C (UV-C) radiation for varying durations could enhance conidial production in C. cassiicola isolates. Eight isolates from cotton and soy were used, grown in V8 juice medium. After five days of incubation in a climate-controlled chamber, each isolate either underwent mycelium scraping or remained unscraped and was subsequently exposed to UV-C radiation for either 1.0, 1.5 or 2.0 min, in comparison to a control group with zero UV exposure time. Following these procedures, conidial suspensions from each isolate were obtained and quantified (conidia per mL) using a Neubauer chamber The ISO 3S and ISO 4S isolates were found to produce more conidia than the other isolates, regardless of whether they were subjected to mycelium scraping or exposure to UV-C radiation. For most isolates, exposure to UV-C radiation for 1.0-1.5 min led to increased conidium production. Generally, it was not feasible to discern differences in conidial production with respect to the mycelium scraping process. Nevertheless, exposure to UV-C radiation for 1.0 min can be used to induce conidium production in C. cassiicola isolates.

Pakistan’s Energy infrastructure is not well developed, rather it is considered to be underdeveloped and poorly managed. Currently the country is facing severe energy crisis. Despite of strong economic growth and rising energy demand during past decade, no serious efforts have been made to install new capacity of generation. The use of various power sources like generators, UPS, solar system with DC power lines and DC loads as well as with UPSs for their requirements is most common in the country. Nowadays the most common system is DC loads with batteries and solar chargers. The basic drawback of DC system is the voltage regulation for DC home appliances, whenever batteries are fully charged the light intensity of lamps and speed of fans increased and may also damage appliance. While decrease in battery decreased the light intensity of lamps and speed of fans. For this problem a system automatic voltage regulator for DC appliance based on Arduino has been made. It is based on buck boost converter technology, when battery fully charged this does not allow excessive voltage to loads and maintain the desired voltage, when voltage of battery decreased the system increases the voltage to desired level.
En defensa del orden: la cultura profesional de la policía en la Segunda República, 1931-1936
Authors: Vaquero Martínez Sergio
Published: July 2024

La policía constituyó un agente sociopolítico insustituible en el acontecer de la Segunda República. La mayoría de especialistas identifican como causa primordial de su comportamiento el arraigo generalizado de una mentalidad autoritaria y castrense contraria al régimen republicano. Cuestionando dicha idea, el siguiente artículo analiza la cultura policial de aquella época: los discursos, valores, representaciones, identidades, símbolos y prácticas que configuraron su saber profesional y su particular construcción de la realidad. Se defiende que dicha cultura albergaba dos subculturas: una militarizada mayoritaria, otra civil minoritaria, así como algunos atributos característicos de una concepción más profesional y democrática del oficio.
Psiquiatría, derecho penal y peligrosidad social en la Segunda República
Authors: Campos Ricardo
Published: July 2024

Este trabajo analiza los argumentos psiquiátricos y jurídicos que sustentaron la existencia de la peligrosidad social de los enfermos mentales, anormales e inadaptados. Asimismo se estudia cómo durante la Segunda República la convergencia entre psiquiatras y juristas fue decisiva en la creación de espacios como el Instituto de Estudios Penales (1932) y el Servicio de Biología Criminal (1933) en los que compartían responsabilidades, así como en la promulgación de la Ley de Vagos y Maleantes (1933) dirigida a combatir comportamientos considerados potencialmente peligrosos por medio de la prevención y la aplicación de medidas de seguridad de carácter rehabilitador.
«Hablemos ya de conciliación»: Valentín Ortigosa y su crítica al proyecto de pacificación en América, 1813-1823
Authors: Rodríguez Tapia Andrea
Published: July 2024

Este trabajo estudia la trayectoria del presbítero Valentín Ortigosa, analizando los textos que dedicó al tema de las insurrecciones en la América española entre 1813 y 1823. Contrario a los proyectos que buscaban la «pacificación» de aquellos territorios mediante el uso de la fuerza y las armas, y consciente de la falta de recursos materiales y humanos para reconquistar América por parte del Gobierno español, Ortigosa planteó un proyecto de «conciliación», que llevara a negociar con los americanos el establecimiento de un nuevo tipo de relación. Un proyecto que a mediano plazo implicaría el reconocimiento a las independencias a cambio de garantías comerciales y mercantiles que ofrecieran ventajas a España respecto a otras potencias.
The Northern Studies Collection of the Hokkaido University Library as the Major Repository of Sources on the History of Sakhalin and the Kuril Islands
Authors: Shchepkin Vasilii  V.
Published: July 2024

The article traces the formation and development of the Northern Studies Collection at the Hokkaido University Library, the largest collection of Japanese written sources on the history of Sakhalin and the Kuril Islands in the 17th–19th cc. in Japan and beyond. This region was involved in trade relations with Japanese merchants under the control of the Matsumae clan, and later was partly administered by the Tokugawa shogunate. The Northern Studies Collection of the Hokkaido University Library is based on written sources that were collected and copied nationwide for the compilation of an official history of Hokkaido under the auspices of the island’s governorship in the 1910s–1930s. During the preparation of the catalog in the 1970s and 1980s, the collection was also enriched with copies of many sources from other collections in Japan. Thus, the Northern Studies Collection can be used to reconstruct a map of all the centers for storing sources on the history of the region in Japan. As this extensive collection is closely related to the history of the Northern Studies Collection Department and its predecessor, the Northern Cultures Research Department of the Hokkaido University, the history of these two branches is also traced in the article.
Hukukçu Yazarın Metindeki Varlığı: Juli Zeh ve Oyun Dürtüsü
Authors: Güven Emre Bekir
Published: July 2024

Edebiyat tarihi boyunca sıkça karşılaşılan hukukçu yazarlar, Alman dilinde ve edebiyat geleneğinde “Dichterjurist” kavramını doğurmuştur. Hukuk formasyonuna sahip bu edebiyatçılar veya edebiyat formasyonuna sahip bu hukukçular, iki disiplini çeşitli boyutlarda bir araya getirmiş ve getirmektedirler. Kimi zaman E. T. A. Hoffmann ölçüsünde, kimi zaman Franz Kafka boyut ve felsefesinde, kimi zaman da Bernhard Schlink, Ferdinand von Schirach ve Juli Zeh güncelliğinde iki disiplin arasında multi ve interdisipliner bir alan ortaya çıkmıştır. Özellikle çağdaş Alman edebiyatı çerçevesinde bakıldığında, son döneme ait Dichterjuristlerin, sahip oldukları hukuk formasyonunu bilinçli olarak metinlerine hasrettikleri görülmektedir. Metnin yaratıcısı olarak yazar adeta metinde vardır ve Dichterjurist olduğunu okura hissettirmektedir.
Bu çalışma, Juli Zeh’in, Oyun Dürtüsü romanında hukukçu yazar/Dichterjurist olarak varlığını irdelemektedir. Ada ve Alev’in iki genç öğrenci olarak, oyun dürtüsüyle başlattıkları ve ceza davası ile sonuçlanan bir süreç içerisinde, kanun, hukuk ve adaletin oluşturduğu bir sistematiği, yazarın ne kapsamda ve hangi yaklaşımla ele aldığını sorgulamaktadır. Romanın yazarı olarak Juli Zeh’in dışında kurmaca katmanda, yargılamayı mahkeme hükmü formatı dışında yazma ve okura aktarma kararı alan anlatıcı, yargılamayı yöneten yargıcın kendisidir. Dolayısıyla, sadece gerçek düzleminde değil, kurmaca düzlemde de bir Dichterjurist söz konusudur. Bu olgudan hareketle, hukukçu yazarın metinde somut varlık gösterdiği hipotezine paralel olarak bu çalışma, hukuk formasyonuna sahip yazarın, hukuk sistematiğine dair bilgisini ne ölçüde ve hangi yaklaşımla edebi bir metne yansıttığını ortaya koymayı amaçlamaktadır.
