Published: April 2022

The purpose of the study was to measure the efficiency level of using the budget of public service agencies where one of the government agencies that has implemented financial management of public service agencies is the Universitas Negeri Malang. The object of research is the Faculty of Economics Universitas Negeri Malang by measuring the level of budget efficiency in 2018-2020. The data from this study are internal data, which only comes from the State University of Malang which is obtained directly with documentation. The data obtained at the data collection stage is then processed by calculating the activity output achievement, efficiency, and efficiency value using the formula in the Minister of Finance Regulation Number 214/PMK.02/2017. The results of the study show that the implementation of the Faculty of Economics Universitas Negeri Malang budget during 2018-2020 has been carried out efficiently. The implementation of the 2018 budget in the fairly efficient category, the implementation of the 2019 budget in the efficient category and the implementation of the 2020 budget in the very efficient category. Factors that affect the efficiency of the budget implementation are the percentage of realized activity outputs and the percentage of budget realization. The realization of high activity output achievements and low budget realization will result in efficient budget execution. The implication of this research is that the Faculty of Economics Universitas Negeri Malang must make various efficiency efforts in the years to come by optimizing an increase in the number of activities carried out compared to the number of planned activities, but with efficient use of the budget.

The reason behind this research is the low mathematical ability of the students in geometry. They think that geometry is difficult to comprehend, so that we need a lesson from the teacher in order to make students interested in studying geometry. In order to create interesting learning, teachers need to see students' thinking. Therefore, this research aims to determine students’ thinking ability in solving quadrilateral using Polya’s problem solving steps associated with level descriptors of Van Hiele. This research employed qualitative descriptive study. The subjects of this research were 2 students from each level of visualization, analysis, informal deduction, and 1 student from level of rigor. The initial step of this research was determining the research subject by administering a test, then proceeded by giving a geometry practice test and interviews. The results showed that the students at the visualization and informal deduction both met the indicators of planning, solving, and explaining problems coherently, students at the level of informal deduction also fulfilled the indicators involving previously acquired knowledge to solve problems, the students at the analys level could not fulfill the indicators of analys level, and the students at the rigor level fulfilled one indicator which was using logic in the step of implementing plan.
A retrospective cohort study evaluating demographic and clinical characteristics associated with use of seclusion in a London psychiatric intensive care unit
Authors: Mark Isabel , Bell Darren , Lewis William , Gleeson Siobhan , O'Brien Aileen
Published: March 2022

Seclusion is generally regarded as an important tool for aggression management in those admitted to a psychiatric intensive care unit (PICU). Nevertheless, it remains controversial with concerns regarding the ambiguity of who meets the threshold for seclusion. This study provides a
detailed analysis of those who met the threshold and were secluded, whilst admitted to a London PICU, identifying key demographic features and clinical characteristics associated with seclusion use. All PICU admissions were examined over a one-year period (10 January 2020 – 9 January
2021). Data were collected retrospectively from patient electronic records. 125 patients met inclusion criteria for analysis, of whom 49 (39.2%) had been secluded during their admission and 76 (60.8%) had not. Those secluded included a higher proportion of patients with Black ethnicity (p
= 0.004). A higher proportion of those secluded had been in employment prior to admission with fewer reporting long-term sick leave (p = 0.048). Seclusion was associated with a longer mean admission time (p = 0.02). Those requiring seclusion received higher doses of benzodiazepines
during their admission (p = 0.009). Illicit drug use and forensic history were not found to be factors associated with seclusion use, in contrast to previous studies. Findings indicate that, within this cohort, seclusion is mostly associated with patient demographics and severity of
illness.
Ley de refuerzo del respeto de los principios republicanos en Francia. ¿El regreso del asimilacionismo?
Authors: Georgeault Léna
Published: March 2022

Este artículo estudia la evolución de las prácticas de la República francesa en materia de integración desde principios de siglo XIX hasta la actualidad, con la nueva ley titulada «ley de refuerzo del respeto de los principios republicanos» de 24 de agosto de 2021. Se aportan perspectivas históricas y legales que esclarecen los fundamentos y los objetivos de la praxis francesa. A través de este trabajo se intenta demostrar que el asimilacionismo, fundamentado en el proyecto republicano de unificación de la nación, es un modelo que está resurgiendo parcialmente tras un paréntesis liberal favorable a las reivindicaciones de las minorías. Para llevar a cabo este objetivo, se aborda, en primer lugar, el marco ideológico en el que nace el asimilacionismo; en segundo lugar, se analiza la forma en que ese modelo se fue imponiendo antes de su declive a partir de los años sesenta; y, finalmente, se discute si la nueva ley marca el retorno del asimilacionismo.

Sobre la formación del jurista del siglo XXI (un retablo más o menos utópico con Bolonia como fondo)
Authors: Martín Rebollo Luis
Published: March 2022

luis.martin@unican.es

El presente trabajo pretende ser una reflexión personal acerca de la formación del jurista en la Universidad; sobre lo que se «puede» y lo que se «debe» enseñar o aprender. El autor defiende que más que conocimientos concretos –aunque algunos sean siempre necesarios– lo importante es aprender a moverse por un Ordenamiento plural, asumir los valores que subyacen en él, entender los aspectos centrales o generales sin descender a detalles marginales y aprender a razonar y a exponer oralmente o por escrito una proposición o pensamiento. Esa perspectiva subjetiva, como cualquier otra, está condicionada por lo que se pretenda que sea el objetivo a conseguir, es decir, las finalidades de la enseñanza (si directamente profesional o más generalista). Luego, sea cual sea esa finalidad, la formación está condicionada por los medios y condiciones ambientales: la organización de la universidad y los planes de estudio, pero, por encima de todo, por quienes sean los profesores, lo que abre un debate posterior acerca de su propia selección y formación ante el que el autor se muestra crítico y, en cierto modo, resignado.
Using Digital Storytelling and Game-Based Learning to Increase Student Engagement and Connect Theory with Practice
Authors: Gillespie Bruce
Published: April 2022

Research shows that high levels of engagement help students learn more effectively, feel better about their learning, and improve retention rates. One reason why students report low engagement is a perceived disconnect between theory (what they learn in class) and practice (what happens in the outside world). This paper reports on the results of a small-scale SoTL experiment that increased engagement in a first-year journalism course through the creation of a bespoke interactive web series composed of short videos and choose-your-own-adventure games that immersed students in real-world scenarios. It also offers reflections on the opportunities and challenges of using digital games and storytelling for learning and opportunities for engaging students as partners.

Síndrome hemolítico urémico atípico en lactantes con mutaciones genéticas: Reporte de 3 casos
Authors: Loza Reyner , Arias Fernando , Ynguil Angelica , Rodríguez Nathalie , Neyra Víctor
Published: March 2022

El síndrome hemolítico urémico atípico (SHUa) es una entidad clínica considerada rara; sin embargo, es la causa más común de insuficiencia renal aguda en niños. Esta enfermedad se acompaña de anemia hemolítica microangiopática, trombocitopenia, retención nitrogenada y afectación de la función renal, por lo que representa alta morbilidad y compromiso sistémico. Se reportan tres casos de SHUa en lactantes que presentaron pródromos respiratorios, diarrea, anemia hemolítica y trombocitopenia, con pérdida de función renal. Estos casos mostraron que dicha patología está asociada a mutaciones en los genes: CFH (Complemento Factor H), MCP (Membrana Cofactor Proteín), CFHR1 (Complemento Factor H-Related Proteín1), CFHR5 (Complemento factor H-Related Protein 5) y el gen C3 (Complemento component 3). Los genes CFH y MCP se encontraron afectados en dos de los casos, mientras que el tercer caso mostró una mutación nueva no reportada en el gen C3. Estos resultados evidencian que estas mutaciones están presentes en el Perú, por lo que se debe investigar y establecer medidas de prevención para reducir el alto riesgo de morbilidad y mortalidad que presentan los niños portadores SHUa.
Allergy to the iodinated contrast media – the clinical and immunological aspects – a literature review
Authors: Jenerowicz Dorota , Kanabaj Krzysztof , Adamski Zygmunt , Czarnecka-Operacz Magdalena
Published: March 2022

Aim. The aim of this paper is to analyse and review the currently available evidence and research with regard to allergy to the iodinated contrast media, which still remains an important, albeit rare, clinical complication.
Material and Methods. We performed our research using the PubMed search engine provided by the National Centre for Biotechnology Information, having inserted ‘iodinated contrast media’, ‘allergy’, ‘adverse reactions’ as the keywords.
Results. Even though the modern iodinated contrast media are much safer than those used in the past, adverse reactions still occur in up to 1–3% of patients undergoing radiological procedures. Their range varies from skin changes, such as a macular rash, prurigo or urticarial, to the more severe multisystemic reactions including anaphylactic shock. The underlying mechanisms are still investigated and are not fully comprehended, although the most frequently accepted explanations include a systemic inflammatory reaction associated with increased histamine and tryptase levels, activation of memory T cells and both direct and indirect damage to the vascular epithelium. The significance of classic allergy tests has not yet been fully established. The associated known risk factors are of various character and researchers have come with different, occasionally contradicting results regarding patients’ age and gender, however, other factors have been more clearly described, and include concomitant conditions and medications.
Conclusions. The aforementioned data emphasizes the importance of clinical aspects of allergy to the iodinated contrast media for every practicing physician, as more and more medical specialties benefit from the advantages of modern vascular imaging.

Efficient Operations of Micro-Grids with Meshed Topology and Under Uncertainty through Exact Satisfaction of AC-PF, Droop Control and Tap-Changer Constraints
Authors: Bragin Mikhail A. , Yan Bing , Kumar Akash , Yu Nanpeng , Zhang Peng
Published: March 2022

Micro-grids’ operations offer local reliability; in the event of faults or low voltage/frequency events on the utility side, micro-grids can disconnect from the main grid and operate autonomously while providing the continued supply of power to local customers. With the ever-increasing penetration of renewable generation, however, the operations of micro-grids become increasingly complicated because of the associated fluctuations of voltages. As a result, transformer taps are adjusted frequently, thereby leading to the fast degradation of expensive tap-changer transformers. In the islanding mode, the difficulties also come from the drop of voltage and frequency upon disconnecting from the main grid. To appropriately model the above, the nonlinear AC power flow constraints are necessary. Computationally, the discrete nature of tap-changer operations and the stochasticity caused by renewables add two layers of difficulty on top of a complicated AC-OPF problem. To resolve the above computational difficulties, the main principles of the recently-developed "l1-proximal" Surrogate Lagrangian Relaxation are extended. Testing results based on 9-bus system demonstrate the efficiency of the method to obtain the exact feasible solutions for micro-grid operations thereby avoiding approximations inherent to existing methods, while demonstrating that through the optimization, 1. the number of tap changes is drastically reduced, and 2. the method is capable of handling networks with meshed topologies.

Published: March 2022

In the context of all-digital radar systems, phase-modulated continuous wave (PMCW) based on pseudorandom binary sequences (PRBSs) appears a prominent candidate modulation scheme for applications such as autonomous driving. Among the reasons for that are its simplified transmitter architecture and lower linearity requirements, e.g., compared to orthogonal-frequency division multiplexing radars, as well as its high velocity unambiguity and multiple-input multiple-output operation capability that are characteristic of digital radars. For appropriate operation of a PMCW radar, choosing a PRBS whose periodic autocorrelation function (PACF) has low sidelobes and high robustness to Doppler shifts is paramount. In this sense, this article performs an analysis of Doppler shift tolerance of the PACFs of typically adopted PRBSs in PMCW radar systems supported by simulation and measurement results. To accurately measure the Doppler-shift-induced degradation of PACFs, peak power loss ratio (PPLR), peak sidelobe level ratio (PSLR), and integrated-sidelobe level ratio (ISLR) were used as metrics. Furthermore, to account for effects on targets whose ranges are not multiples of the range resolution, oversampled PACFs are analyzed.
ANALISIS KINERJA SIMPANG EMPAT NONONGAN DENGAN PENGGUNAAN WAKTU SINYAL DOUBLE CYCLE PADA PENERAPAN CONTRA FLOW BUS LANE
Authors: Setiono Setiono , Yulianto Budi
Published: March 2022

Traffic jams and accidents on urban roads are a challenge for the city government in carrying out traffic management and engineering efforts. The intersection is the meeting point of various traffic movements from each intersection approach that has the potential to cause traffic jams and accidents. One of the traffic management and engineering efforts carried out by the Surakarta City Government is by providing public transportation services for Batik Solo Trans in serving the movement of people's journeys. The implementation of the contra flow bus lane on Jalan Brigjen Slamet Riyadi, Surakarta City is part of the Surakarta City Government's efforts to provide a reliable public transportation system. However, the implementation of the contra flow bus lane has an impact on the performance of signalized intersections along Jalan Brigjen Slamet Riyadi, one of which is the Nonongan Empat Junction. This study aims to streamline the timing of the APILL signal by using a double cycle at the Simpang Empat Nonongan. Evaluation of intersection performance uses a simulation modeling approach with the VISSIM simulation program. The results of the Base output performance of the VISSIM simulation model with the existing signal time are compared with the VISSIM simulation model scenario using a double cycle signal time. The use of double cycle signal time shows the intersection performance is more effective than using the existing signal time. Intersection delays decreased by 13.6% for the morning rush hour and 18.8% for the afternoon rush hour.

Decay of a Roman age pine wood studied by micro magnetic resonance imaging, diffusion nuclear magnetic resonance and portable nuclear magnetic resonance
Authors: Stagno Valeria , Capuani Silvia
Published: March 2022

Wood is a hygroscopic biodegradable porous material widely used by men in the past to create artworks. Its total preservation over time is quite rare and one of the best preservation modalities is waterlogging. Observing the anatomy of waterlogged archaeological wood could also be complicated because of its bacterial degradation. However, the characterization of wood morphology and conservation state is a fundamental step before starting any restoration intervention as it allows to extract information about past climatic conditions and human activities. In this work, a micro-invasive approach based on the combined use of high-resolution magnetic resonance imaging (MRI) and diffusion-nuclear magnetic resonance (NMR) was tested both on a modern and an ancient pine wood sample. Furthermore, a completely non-invasive analysis was performed by using portable NMR. This multi-analytical NMR approach allowed to highlight the effect of decay on the wood microstructure, through alterations in the pores size, tortuosity, and images contrast of the ancient pine compared to the modern one. This work pointed out the different but complementary multi-parametric information that can be obtained by using NMR and tested the potential of high-field MRI and low-field portable NMR in the detection of wood diagnostic features.
Digital Twin: a new perspective for cultural heritage management and fruition
Authors: Gabellone Francesco
Published: March 2022

This paper describes the example of an interesting distance visit approach carried out during the COVID-19 emergency, applied to an underground oil-mill in the town of Gallipoli (Puglia, Italy). The limitations of access for people with disabilities and the complete closure of Italian museums during the emergency have suggested the development of an immersive platform, in the broader perspective of using the output in accordance to digital twin perspectives. Then a tool to support an innovative visit method has been realized: a virtual visit assisted by a real remote guide, hereinafter referred to as “Live-Guided Tour” with e-learning functionality. All this has been made possible starting from a three-dimensional model of an underground oil-mill, from which we extracted the stereoscopic scenes. The stereoscopy is very important for the overall success of the project, because this aspect influences the level of interest, the immersion and the ability to generate emotion and wonder. To the best of Author’s knowledge, this is the only system available today for a shared virtual visit for an inaccessible context, which implements many features of a VR visit in a multi-user and multi-platform environment.

Published: March 2022

In the field of Cultural Heritage, the interdisciplinary and multi-technique approach to the study of ancient artifacts is widely used, providing more reliable and complementary results. To study these great value objects, non-invasive approach is always preferred, although micro-invasive techniques may be necessary to answer specific questions. In this work, a study based on both non-invasive and micro-invasive techniques in a two-step approach was applied as a powerful tool to characterize materials and their layering, as well as to get a deeper understanding of the artistic techniques and the conservation history. The object under study is an ancient Egyptian wooden statuette, belonging to the collections of the Museo Egizio of Torino. Analyses were performed at the Centro Conservazione e Restauro “La Venaria Reale” (CCR), starting from non-invasive multispectral and X-ray imaging on the whole object in order to obtain information about the technique of assembly and on some aspects of the constituents materials, and subsequently, non-invasive XRF analysis and FT-IR, SEM-EDX and optical microscopy on micro-samples. This work is intended to lay the groundwork to the study of other wooden objects and statuettes belonging to the same funerary equipment, with the definition of a measuring protocol to study the most significant aspects of the artistic technique.
Feasibility and performance analysis in 3D printing of artworks using laser scanning microprofilometry
Authors: Mazzocato Sara , Marchioro Giacomo , Daffara Claudia
Published: March 2022

We investigated optical scanning microprofilometry and conoscopic holography sensors as nondestructive testing and evaluation tools in archeology for obtaining an accurate 3D printed reproduction of the data. The modular microprofilometer prototype allows a versatile acquisition of different materials and shapes producing a high-quality dataset that enables surface modelling at micrometric scales from which a "scientific" replica can be obtained through 3D printing technologies. As exemplar case study, an archeological amphora was acquired and 3D printed. In order to test the feasibility and the performance of the whole process chain from the acquisition to the reproduction, we propose a statistical multiscale analysis of the surface signal of object and replica based on metrological parameters. This approach allows to demonstrate that the accuracy of the 3D printing process preserves the range of spatial wavelengths that characterizes the surface features of interest within the technology capabilities. This work extends the usefulness of the replicas from museum exposition to scientific applications.
Fire SM: new dataset for anomaly detection of fire in video surveillance
Authors: Mali Shital , Khot Uday
Published: March 2022

Tiny datasets of restricted range operations, as well as flawed assessment criteria, are currently stifling progress in video anomaly detection science. This paper aims at assisting the progress of this research topic, incorporating a wide and diverse new dataset known as Fire SM. Further, additional information can be derived by a precise estimation in early fire detection using an indicator, Average Precision. In addition to the proposed dataset, the investigations under anomaly situations have been supported by results. In this paper different anomaly detection methods that offer efficient way to detect Fire incidences have been compared with two existing popular techniques. The findings were analysed using Average Precision (AP) as a performance measure. It indicates about 78 % accuracy on the proposed dataset, compared to 71 % and 61 % on Foggia dataset, for InceptionNet and FireNet algorithm, respectively. The proposed dataset can be useful in a variety of cases. Findings show that the crucial advantage is its diversity.

Measurement of medical data and extraction of medical images with various sensory systems have become a crucial part of diagnosing and treating various diseases. In this contest measurement technology plays a key role in diagnosis. Medical experts usually use previous case studies to identify and deal with the current medical condition. In this context, an expert required to explore the large medical database to search relevant images for the required analysis. Searching such large database and retrieving an image efficiently becomes very tedious task. Therefore, this paper proposed a measurement-based image reconstruction using the refined Res-UNet Framework for Medical Image Retrieval (MIR) for managing such crucial tasks and reduce complexities. The proposed two stage framework consists of an image reconstruction using Res-UNet and index similarity matching of query image with history images. Res-UNet is a vanilla combination of ResNet50 as an encoder that gives latent information of input image, and the decoder from UNet reconstructs the image using latent information. Further, those latent features match similar image features and retrieve indexed images from the medical image database. The efficacy of proposed method was confirmed on benchmark medical image databases such as ILD and VIA/ELCAP-CT for MIR. The proposed framework outperforms the existing methods in the task of MIR.

Magnetic Resonance (MR) brain Image is very important for medial analysis and diagnosis. These images are generally measured in radiology department to measure images of anatomy as well as the general physiological process of the human body. In this process magnetic resonance imaging measurement are used with a heavy magnetic field, its gradients along with radio waves to produce the pictures of human organs. MR brain image is also used to identify any blood clots or damaged blood veins in the brain. A counterfeit neural organization is a nonlinear information handling model that have been effectively used preparation models for tackling administered design acknowledgment assignments because of its capacity to sum up this present reality issues. Artificial Neural Networks (ANN) is used to classify the given MR brain image having Benign or Malignant tumour in the brain. Benign tumours are generally not cancerous tumours. These are also not able to grow or spread in the human body. In very rare cases they may grow very slowly. Once it is eliminated, they do not come again.  On the other hand, Malignant tumours are cancer tumours. These tumour cells are grown and also easily spread to other parts of the human body. Benign also known as Harmless. These are not destructive. They either can't spread or develop, or they do as such leisurely. On the off chance that a specialist eliminates them, they don't by and large return. Premalignant In these growths, the cells are not yet harmful, however they can possibly become threatening. Malignant also known as threatening. Malignant growths are destructive. The cells can develop and spread to different pieces of the body. In our proposed framework initially, it distinguishes Wavelet Transform to separate the highlights from the picture. Subsequent to separating the highlights it incorporates tumour shape and power attributes just as surface highlights are distinguished. Finally, ANN to group the information highlights set into Benign or Malignant tumour. The main purpose as well as the objective is to identifying the tumours weather it belongs to Benign or Malignant.

This study aims to determine the effect of citric acid concentration and immersion time on the characteristics of pineapple cobs candy using  factorial randomized block design. The first factor was the concentration of citric acid (P): 0.2% (P1), 0.35% (P2), and 0.5% (P3), the second factor was immersion times (T): 12 hours (T1), 15 hours (T2) and 18 hours (T3). Statistical analysis used was analysis of variance and Tukey’s Honest Significant Difference at 5% level. Results showed that there was significant interaction between the concentration of citric acid and immersion times on the ash content of pineapple cobs candy. Concentration citric acid had significant effect on vitamin C content and lightness. Immersion times had significant effect on moisture content. Citric acid concentration and immersion times has significant affected on hedonic test of color, texture and taste. The best treatment was P2T1 (citric acid concentration 0.35%, immersion times 12 hours) with the characteristics ash content of 0.641%, water content of 10.966%, vitamin C content of 0.469%, lightness of 48.957, and color organoleptic value of 4.200, aroma of 5,433, texture of 5,100 and taste of 5,467.

Poly-,Per-fluorinated alkyl substances (PFAS) are versatile chemicals that were incorporated in a wide range of products. One of their most important use was in aqueous film-forming foams for fighting liquid fuel fires. PFAS compounds have recently been identified as potential environmental contaminants. In the United States there are hundreds of potential military sites with PFAS contamination. The ERDC designed and constructed a mobile treatment system to address small sites (250,000 gallons or less) and as a platform to field test new adsorptive media. The PFAS Effluent Treatment System (PETS) has cartridge filters to remove sediments and a granular activated carbon (GAC) media filter to remove organic compounds that might compete with PFAS in the ion exchange process, although it may also remove PFAS too. The last process is an ion exchange resin specifically designed to remove PFAS to a target level of 70 ng/L or less (equivalent to the US Environmental Protection Agency (EPA) Drinking Water Health Advisory). The system was tested at Hurlburt Field, a US Air Force facility in Florida and at Naval Support Activity (NSA) Mid-South in Millington, TN.

Analytical methods to rapidly detect explosive compounds with high precision are paramount for applications ranging from national security to environmental remediation. This report demonstrates two proof-of-concept electroanalytical methods for the quantification of 2,4-dinitroanisol (DNAN) and pentaerythritol tetranitrate (PETN). For the first time, DNAN reduction was analyzed and compared at a bare graphitic carbon electrode, a polyaniline-modified (PANI) electrode, and a molecularly imprinted polymer (MIP) electrode utilizing PANI to explore the effect of surface-area and preconcentration affinity on the analytical response. Since some explosive compounds such as PETN are not appreciably soluble in water (<10 μg/L), necessitating a different solvent system to permit direct detection via electrochemical reduction. A 1,2-dichloroethane system was explored as a possibility by generating a liquid-liquid extraction-based sensor exploiting the immiscibility of 1,2-dichloroethane and water. The reduction process was explored using a scan rate analysis to extract a diffusion coefficient of 6.67 x 10⁻⁶ cm/s, in agreement with literature values for similarly structured nitrate esters. Once further refined, these techniques may be extended to other explosives and combined with portable electrochemical hardware to bring real-time chemical information to soldiers and citizens alike.
Dissent in court and in literature: the brazilian technique of adding collegiate members to court and the «Minority report»
Authors: Gondim Victor Sampaio
Published: April 2022

This paper is an analysis of how the event of outvoting is seen in the Brazilian procedural order, especially regarding the introduction of a technique for expanding the number of court members, which replaced the Motions for Reconsideration in the edition of the 2015 Brazilian Code of Civil Procedure. The research is developed from the narrative lived by the character John Anderton, of the short story The Minority Report, by Philip K. Dick. The relevance of the study comes from the need to evaluate the recent, deep changes in procedural law when it comes to dissenting opinions in court. The investigation is of bibliographic-documental type, with an analogy between the literary and the legal environments, in a theoretical research with qualitative approach, descriptive and exploratory regarding the results. The conclusion is that, similarly to fiction, the new judgement technique seeks to grant the debate within courts regarding the event of outvoting, with aims at providing more rationality to trials and avoiding a merely formal approach to dissent.
