Kindergrundrechte
Authors: Hepp Christine
Published: January 2022

Children are only explicitly mentioned in the Basic Law as the subject of the norm and the object of parental care. The thesis explores both the existence and formulation of fundamental rights in relation to children according to the case law of the Federal Constitutional Court as well as the underlying fundamental rights dogmatics of the Court. In this way, an overall picture of the current constitutional status of the child in Germany is established. The study aims to shed light on the controversy in the points that have been insufficiently addressed so far and to resolve underlying misunderstandings. Finally, it serves to clarify the constitutional status of children in Germany.

Published: January 2022

The organisation and competences in the field of aviation security in Germany are fragmented. In order to develop proposals for a possible reform of the organisation and performance of tasks, the current system of aviation security was comprehensively analysed with special regard to passenger and baggage controls. For this purpose, the current situation was recorded and compared with the situation in other countries. The study took into account the perspectives of all relevant stakeholders in the field of aviation security (e.g. aviation security authorities, airport operators, airlines, aviation security companies). Based on these results, possible reform proposals were developed.
Die Strafbarkeit der Fluchthilfe
Authors: Trinh Julia
Published: January 2022

Currently, legal migration is barely impossible, which is why refugees regularly place themselves in the hands of so-called smugglers. These smugglers usually act for their own profit. They lead the refugees along dangerous routes, some of which also lead across the Mediterranean Sea, and can therefore be considered criminals. They shall be countered with the criminal offense of § 96 German Residence Law. However, the legislator's intention goes astray since private flight helpers, who act out of solidarity, are also criminalized. Given this grievance, the author points out the dogmatic weaknesses of § 96 German Residence Law and presents a proposal for an urgently needed reform of this so-called smuggling offence.
„Nun geht der Unsinn an“
Authors: Thielsen Jill
Published: January 2022

Die Studie fokussiert Texte, die häufig unter den aus Wertungshandlungen entstandenen Termini ‚Unsinns-‘ und ‚Nonsenspoesie‘ rubriziert werden, und problematisiert die damit verbundene Tendenz zur Homogenisierung literarischer Artefakte, die zwar similäre ästhetische Verfahren erkennen lassen, aber aus disparaten Kontexten stammen. Auf Basis semiotischer Analysen von z. B. Peritexten und mit Bezug auf literatursoziologische Theorieangebote fragt sie dagegen, wie Texte, die vor dem Hintergrund eines zum Publikationszeitpunkt geltenden Literaturparadigmas als deviant gelten, in den literarischen Kommunikationsprozess eingespeist werden und welche rekurrenten Semantiken und Funktionen sich anhand kommunikativer Rahmungen extrapolieren lassen.
Introduction
Authors: Aspray Silvianne
Published: January 2022

This introduction makes the case that the avowedly anti-metaphysical stance of many reformers is itself a metaphysical position and proposes a method by which to investigate it. It argues that question ‘What was the metaphysics of the Reformation?’ cannot be addressed using purely historical methods. Instead, it proposes a philosophical-theological approach, suggesting that understandings of being and of causality constitute a useful heuristic lens through which to read Reformation sources with a view to understanding their implied metaphysics. It also outlines the aims of the book and the rationale for focussing on Vermigli as a case study.

Why Song in Verlaine’s Verse is Always Already Beyond the Nation
Authors: Dayan Peter
Published: January 2022

The poems Verlaine published up to 1886 contain very frequent references to song, and many references to the nation. But only three poems refer to both; and in all three cases, the relationship between song and the nation is presented as necessarily archaic, belonging to a lost monarchic time. For Verlaine, in his own time, the poet must keep song and the nation strictly separate. Song must be a transnational ideal, always identified with the pure azure of the sky, always already beyond the nation. This ideal song is divorced from the real, audible popular songs that Verlaine knew, sang, and occasionally evokes in his poetry. Those popular songs are national in the sense that they are in a specific national language. Precisely for that reason, he refuses to dignify them with the title of song, ‘chanson’ or ‘chant’. Verlaine’s transnational idealism, expressed in his concept of wordless, transnational song, turns out to be inseparable from his violent misogyny. He wanted to see his wife as pure song, as pure as the azure of the sky; when she turned out to have a voice in a national language, his love turned to violent revenge.
Johanna Müller-Hermann’s Lied der Erinnerung: Austria, America, and Beyond
Authors: Ronyak Jennifer
Published: January 2022

Scholarship on musical settings of Walt Whitman’s When Lilacs Last in the Dooryard Bloom’d has only briefly looked into one of the most ambitious pieces composed on the poem in the earlier twentieth century: the Austrian woman composer Johanna Müller-Hermann’s orchestral cantata Lied der Erinnerung, premiered in Vienna in 1930. Through the piece has not remained in the repertoire, seen in light of its original context the cantata was a rich site for negotiating a complex terrain of ‘American’, ‘Austrian’, and ‘universal’ concepts. Through her structural decisions involving Whitman’s poem, her attempts to have the work reach American audiences, her use of borrowed melodies, and claims made in the work’s program notes, Müller-Hermann situated the work carefully between these competing frames while seeking to achieve critical success as a woman composer. The Whitmanesque vision of America that Müller-Hermann created would have also had a politically charged significance in both Austria and the U.S. in the period surrounding the work’s premiere.
Conceptualising Post-Transition Disappearances
Authors: Payne Leigh A. , Ansolabehere Karina
Published: January 2022

This chapter establishes a holistic approach to understanding disappearances in post-transition countries. It considers the historical repertoires of disappearance that emerge during periods of authoritarian rule and armed conflict. It further argues that four logics behind disappearances in those situations continue into the post-transition. These include the clandestine logic, or hiding crimes against humanity from domestic and international scrutiny. Those disappearances also tend to involve marginalised populations; a ‘disposable people’ logic creates framing devices that transform citizens into those without rights or visibility. A political-economy logic emerges with cheap and exploitable workers, who are disappeared when their labour utility is exhausted; those with economic and political power commit these atrocities with impunity. The logic of ambiguous loss becomes a form of social control. Grieving processes are blocked when relatives lack certainty that the person is gone. They further lack the necessary evidence of death and wrongdoing to pursue redress. These four logics together, the project contends, explain why disappearances previously studied only in authoritarian or armed conflict contexts prevail also in the post-transition.
My Promise to Look for You
Authors: Herrera Lulú , Cuellar Paula Cuellar
Published: January 2022

Lulú Herrera tells her story of the search for her disappeared husband, eight-year-old son, and two brothers-in-law. In the process, Herrera discovered others searching for the disappeared and with them she became a founding member of the organisation Forces United for Our Disappeared in Coahuila, Mexico. She realised how invisible these disappearances are even when the numbers are so high. Indeed, they were unknown to her before her own life was transformed by disappearance. She was forced to become a different person to be able to carry out the search. A search that continues for her family members and those of others in Coahuila.
The Legal Framework on Disappearances in Mexico: From Demands to the Law and Back to Demands
Authors: Serrano Sandra , de Pina Ravest Volga
Published: January 2022

This chapter explains that the General Law on Disappearances in Mexico is a legal change achieved by a broad mobilisation of families of victims of disappearance in a challenging context of persistent violence in the country. The Law helps to improve the relevant standards related to searching for disappeared persons, guaranteeing the rights of the victims’ families, furthering the investigation of forced disappearance caused by the government and/or individuals, as well as creating the institutional structures focused on the search for persons. Despite this, the law’s innovative advances coexist alongside previous institutional mechanisms that perpetuate practices contrary to the rights of victims and their families, which risk neutralising the Law. Accordingly, the chapter focuses on the promotion of legal mobilisation strategies in countries, such as Mexico, which accept normative and institutional changes without worrying about their enforcement, since, in practice, new provisions clash with previously created structures that have similar legal authority but greater decision-making power, and are, thus, better able to exercise that authority.
Systematic Recurrence of Murders and Disappearances in Democratic Brazil
Authors: Weichert Marlon Alberto
Published: January 2022

In the post-transition period, Brazil has experienced extremely high levels of lethal violence, perpetrated by both criminal groups and public security forces, which has primarily targeted poor black youths. Despite this high level of violence in a democracy, state agencies persist in their failure to carry out effective measures to reduce and prevent systematic death and disappearance, and to investigate and prosecute homicides and disappearances that victimise this population. Evidence of summary execution and enforced disappearance, moreover, indicate that the Brazilian state is also responsible for a significant portion of these crimes. In response, public authorities have recently adopted a public discourse of crime prevention that exempts police from being held accountable for killing criminal suspects and even encouraging the murder of those criminal suspects during police operations. This chapter argues that the systematic death and disappearance of these civilian populations may be seen conceptually as a crime against humanity, as defined in the Rome Statute. While prior to 2019 it was possible to argue that the killing of poor black youths constituted a policy of omission, after that year evidence suggests that Brazilian security agents have crossed a threshold into actively committing a systematic crime against humanity against citizens.
A New Generation of Disappearances: Gangs and the State in El Salvador
Authors: Méndez María José
Published: January 2022

Around 17,000 Salvadorans have disappeared in the third decade of the post-conflict period (2010-2020). This number more than doubles the estimated 8,000 people who disappeared during the Salvadoran Civil War (1980-1992). Despite its astounding scale, the phenomenon of disappearance in El Salvador has garnered little attention from the international community and has yet to be fully examined. This chapter redresses this invisibility by contrasting a top-down and a bottom-up view on the phenomenon. According to state government officials, disappearances primarily occur at the hands of the Mara Salvatrucha and Barrio 18 gangs. Those inhabiting the peripheries of El Salvador and suffering the deep psychological impact of having a missing relative also hold transnational gangs responsible. However, they connect the phenomenon to abuses by state forces and to complex entanglements between state agents and gangs. Drawing on fieldwork conducted in El Salvador in 2018, this chapter argues that the new generation of disappearances in El Salvador must be analysed in relation to a broader continuum of state violations and state-criminal relations. It also points to the crucial need to engage the perspectives of relatives of the disappeared to make fuller sense of the phenomenon

But it wasn't revealed the prerequisites for the growth of the petroleum industry and the military and industrial complex. The results of the study represent practical recommendations for the industrial development strategies.
Listening to music in the context of developing and encouraging creative thinking in upper elementary school students
Authors: Živković Vesna
Published: January 2022

The subject Music Culture, and especially the subject area Listening to Music, with its carefully designed procedures, methods, and activities, enables the enrichment of the spiritual aspect of the student's personality, as well as its harmonious development. Music is a source of positive emotions, pleasure and aesthetic experience, and is one of the favorite student activities. The paper discusses the problem of whether listening to music encourages and develops creative thinking in students. The sample included students in the fifth, sixth, and seventh grades of primary school (N = 108). Creative thinking was measured by a modified Torrance test of creative thinking. During the testing, the experimental group was exposed to the influence of auditory examples provided by the curriculum, while the control group performed the test without the presence of an auditory stimulus. The results of the research showed statistically significant differences between the control and experimental groups, which confirms that listening to music encourages and develops creative thinking in students.

This paper aims to point out the possibilities of applying the project model of work in the teaching of mathematics. Based on the results of previous research on this issue, as well as recommendations from the Program of teaching and learning for the first cycle of primary education, a model of project-based learning of content on measurement and measures is presented, which can serve to support teachers in organizing and affirming project-oriented teaching mathematics.
The predictive effects of students' perception of teaching practices in TV instruction on students' self-efficacy
Authors: Plazinić Ljiljana
Published: January 2022

The COVID-19 pandemic forced school closures worldwide. TV instruction became one of the main distance-learning modalities across the globe. Given the scarce evidence of effects of TV instruction on students and broad evidence that quality of teaching is a vital factor of students' achievements and motivational beliefs, the main objective of this study is to examine the relationship between the perceived quality of TV teaching practices and one of the most important student outcomes - academic self-efficacy. Sample consisted 1904 primary and lower secondary students. We constructed two measures of self-efficacy: a general measure of student's selfefficacy with regard to the subject and a situational measure of self-efficacy towards the current TV lesson. Students' perception of teaching practices was measured by a composite scale made of ten statements. We conducted regression and mediation analysis in order to identify potential mediation of general self-efficacy in the given subject. Students' perception of teaching practices was found to be a significant predictor that explained 40.55% of the variance of situational self-efficacy towards the current lesson, and the 14% of total effect was mediated by general students' self-efficacy. The results indicate that, even in the indirect and asynchronous TV instruction, teachers can nurture student self-efficacy towards current lessons and tasks by creating a supportive environment, providing clear representation of knowledge, emphasizing the relevance of the learning content by linking the new material and concepts to the students' life experiences and prior knowledge, and by giving challenging tasks to enhance students' engagement.
Trends in primary school teachers' experience over the first year of the COVID-19 pandemic in Serbia: A narrative analysis
Authors: Mićić Katarina , Kovács-Cerović Tünde , Vračar Selena
Published: January 2022

The purpose of the study is to explore the experiences shared by primary school teachers in three waves of data collection. Teachers' narratives about their experiences of schooling during the COVID-19 pandemic were elicited online. In three instances, a total of 116 participants were prompted to narrate in story and letter genres, providing 233 narratives. We conducted the values analysis and additionally analysed data statistically in order to compare the values teachers expressed at three key turning points for education in the first year of the COVID-19 pandemic in Serbia. Altogether, three major values and nine value codes were identified. This multi-genre three-wave approach provided a nuanced and comprehensive picture of teachers' most important impressions, concerns, and strategies in the new reality, in particular as the emphasis changed over the course of one year of the pandemic. Teachers who took part in the first wave mostly focused on health and prevention issues, their duties, the workload, and the strategies for coping with the new normal. In the second wave, as the threat eased, teachers expressed increased awareness of schooling related issues. Teachers' narratives in the third wave primarily focused on the learning process and outcomes. Based on the conducted analyses, the paper draws policy recommendations.

A sense of order in mathematics
Authors: Diehl Digby
Published: January 2022

For the past ten years educators have been engaged in an important controversy over the place of mathematics in the elementary school curriculum. This cont roversy has raised several fundamental questions about the nature of mathematics as a body of intellectual inquiry and about the effectiveness of methods of teaching mathematics. More significantly, it has cast serious doubt on the way in which all subjects are being taught in American schools today. From a different view, however, it has also caused us to review the basic purposes of education in America and to see whether our teaching methods and our subject curriculums now fulfill the basic educational needs of students.

Because of changes in the elementary school mathematics program, in-service education for teachers of the elementary school has been recognized in recent years as a necessity by many teachers, administrators, and college personnel. The Arithmetic Teacher has from time to time reported on in-service programs conducted in various places. In the November, 1963, issue of The Arithmetic Teacher the editor of “Focal point” raised a number of questions about in-service programs.2 Persons interested in reacting to the questions were invited to submit their responses to him.3
Research Commentary: A Gap-Gazing Fetish in Mathematics Education? Problematizing Research on the Achievement Gap
Authors: Gutiérrez Rochelle
Published: January 2022

A substantial amount of research in mathematics education seeks to document disparities in achievement between middle-class White students and students who are Black, Latina/Latino, First Nations, English language learners, or working class. I outline the dangers in maintaining an achievement-gap focus. These dangers include offering little more than a static picture of inequities, supporting deficit thinking and negative narratives about students of color and working-class students, perpetuating the myth that the problem (and therefore solution) is a technical one, and promoting a narrow definition of learning and equity. I propose a new focus for research on advancement (excellence and gains) and interventions for specific groups.
How Mathematicians Determine if an Argument Is a Valid Proof
Authors: Weber Keith
Published: January 2022

The purpose of this article is to investigate the mathematical practice of proof validation—that is, the act of determining whether an argument constitutes a valid proof. The results of a study with 8 mathematicians are reported. The mathematicians were observed as they read purported mathematical proofs and made judgments about their validity; they were then asked reflective interview questions about their validation processes and their views on proving. The results suggest that mathematicians use several different modes of reasoning in proof validation, including formal reasoning and the construction of rigorous proofs, informal deductive reasoning, and examplebased reasoning. Conceptual knowledge plays an important role in the validation of proofs. The practice of validating a proof depends upon whether a student or mathematician wrote the proof and in what mathematical domain the proof was situated. Pedagogical and epistemological consequences of these results are discussed.

Published: January 2022

This article details the design and implementation of a professional development model called Learning Trajectory-Based Lesson Study focused on issues of equity, identity, and agency. We developed the Vertical Articulation to Unpack the Learning Trajectory (VAULT) tool to orient teachers’ instructional planning toward an asset-based view of students’ mathematics competencies. We examined teachers’ use of the VAULT to plan, implement, and debrief on student strategies for one spatial reasoning task in elementary, middle, and high school classrooms. The VAULT facilitated intentional planning for a progression of anticipated strategies and equitable access to instruction. Teachers demonstrated an asset-based view of all student thinking independent of grade-level expectations.
Embodied Micro-Transitions
Authors: Yagi Junichi
Published: January 2022

Employing multimodal conversation analysis, this article examines a single episode of interaction taken from a studio session, during which two musicians check a chord progression. It illustrates how intra-activity micro-transitions are solely achieved through embodied actions. The detailed analysis reveals (a) how the suspension of “playing-along” is occasioned to exhibit participants’ orientation to auditory objects whose “turning-on” makes relevant disengagement from other interactional involvements; and (b) how the temporal complexities of multiactivity are contingently managed in exclusive order, explicating (c) members’ embodied practices for working around the organizational constraints of the auditory objects.

FROM LINGUISTIC FEATURES TO CULTURAL PATTERNS
Authors: Agersnap Anne , Johansen Kirstine Helboe
Published: January 2022

This article discusses the concept of reading and presents a method thatcombines distant and close reading, while drawing on insights fromcomputational humanities. Focusing on basic features in language, distantreading allows for the construction of new types of text. By close reading thesetexts, it is possible to analyse cultural patterns across individual texts. Thismethod of reading is illustrated by two cases stemming from a project basedon a corpus of 11,955 Danish sermons. The first case begins with a distantreading of gendered pronouns in the corpus. The second case begins with adistant reading of named agents.*
The experience of converting former industrial sites to housing facilities
Authors: Vasileva Alina
Published: January 2022

The subject of this research is the process of converting former industrial sites to residential facilities. The object is the housing stock of Moscow. The author explores the theoretical aspects of reproduction of housing stock, giving special attention to conversion of the category of industrial buildings to residential category, which expands the quantitative characteristics of the housing stock. Analysis is conducted on the statistical data of conversion of industrial sites to residential facilities, as well as the available examples of redevelopment of the industrial sites. The conclusion is made that the housing stock is an interlink between many life spheres and the development of its characteristics is required on a permanent basis, which in essence is the reproduction of housing stock through reconstruction, modernization or total building renovation. The implementation of such method as conversion of former industrial sited into residential facilities would contribute to the expansion of the real estate market and increase in the number of residential units, minimizing many issues in the housing stock. The author proves the feasibility of solving issues in the housing stock of the city through conversion of former industrial sites to housing facilities. The novelty of this research lies in the fact that many authors view such method as the solution of disused former industrial buildings, rather than from the perspective of minimization of issues in the housing stock.
Experiment on longitudinal aerodynamic characteristics of flying wing model with plasma flow control

Horizontal tail is eliminated from the flying wing layout for improving the low observable and aerodynamic efficiency, resulting in degrading longitudinal maneuverability and fight stability. The low speed wind tunnel test study of improving the longitudinal aerodynamic characteristics of large aspect ratio flying wing model is carried out by using plasma flow control technology. The flying wing model has a leading-edge sweep angle of 34.5° and an aspect ratio of 5.79. The reasons for deteriorating the static maneuverability and stability of the flying wing model and the mechanism of plasma control of the flow field and longitudinal aerodynamic characteristics are studied by particle image velocimetry (PIV) flow visualization and static force measurement test. The control law of plasma control of the flight maneuverability and stability of the flying wing model is studied through flight test. The fact that the flow separation of the outer wing of the flying wing model occurs earlier than the inner wing and the wing is swept back can result in the forward movement of the aerodynamic center and the deterioration of the longitudinal static stability. The shock disturbance induced by plasma can suppress the flow separation of the suction surface, thereby extending the linear section of the lift curve of the model, preventing the aerodynamic center from moving forward, and improving the longitudinal static stability. When the wind speed is 50 m/s, the plasma control improves the horizontal rudder efficiency at a high angle of attack of the flying wing model, increases the maximum lift coefficient of the model by about 0.1, and postpones the stall angle of attack by more than 4° at different rudder angles. The plasma control allows the flying model to follow the command movement better while flying, increases the flying pitch limit angle from 11.5° to 15.1°, reduces the amplitude of longitudinal disturbance motion by 2°, and reduces the oscillation attenuation time from 15 to 8 s, thereby improving the longitudinal flight maneuverability and stability of the flying wing model. It can be seen that plasma flow control technology has great potential applications in improving the flight quality of flying wing layout.

In this paper, highly correlated ab initio calculations are performed for accurately determining the electronic structures and spectroscopic features of the Λ-S and Ω low-lying electronic states of SbS . The potential energy curves for 27 Λ-S states of the first three dissociation asymptotes are constructed. Spectroscopic constants and vibrational states for all bound states are well determined. The calculated atomic states for both atoms are consistent with experimental data quite well. Several low-lying Ω electronic states are also investigated, and their respective spectroscopic constants and vibrational states are obtained and compared with those of corresponding Λ-S states, which indicates that the spin-orbit coupling effect gives rise to a minor influence on the electronic states of SbS. To verify our computational accuracy, the additional calculations for the low-lying electronic states of PS, AsS and BiS are also carried out. Our derived results are in reasonable agreement with available experimental data. In addition, vibrational spectra from the excited Ω states to the ground state of SbS are simulated, including bands of X(3/2)→X(1/2), 2(1/2)→X(1/2), 4(1/2)→X(1/2), 5(1/2)→X(1/2) and 6(1/2)→X(1/2). The X(3/2)→X(1/2) band is found in the mid-infrared region, while the others are located in the visible region.

Background:

Mitochondrial DNA copy number (mtDNA-CN) is an accessible blood-based measurement believed to capture underlying mitochondrial (MT) function. The specific biological processes underpinning its regulation, and whether those processes are causative for disease, is an area of active investigation.

Methods:

We developed a novel method for array-based mtDNA-CN estimation suitable for biobank-scale studies, called ‘automatic mitochondrial copy (AutoMitoC).’ We applied AutoMitoC to 395,781 UKBiobank study participants and performed genome- and exome-wide association studies, identifying novel common and rare genetic determinants. Finally, we performed two-sample Mendelian randomization to assess whether genetically low mtDNA-CN influenced select MT phenotypes.

Results:

Overall, genetic analyses identified 71 loci for mtDNA-CN, which implicated several genes involved in rare mtDNA depletion disorders, deoxynucleoside triphosphate (dNTP) metabolism, and the MT central dogma. Rare variant analysis identified SAMHD1 mutation carriers as having higher mtDNA-CN (beta = 0.23 SDs; 95% CI, 0.18–0.29; p=2.6 × 10-19), a potential therapeutic target for patients with mtDNA depletion disorders, but at increased risk of breast cancer (OR = 1.91; 95% CI, 1.52–2.40; p=2.7 × 10-8). Finally, Mendelian randomization analyses suggest a causal effect of low mtDNA-CN on dementia risk (OR = 1.94 per 1 SD decrease in mtDNA-CN; 95% CI, 1.55–2.32; p=7.5 × 10-4).

Conclusions:

Altogether, our genetic findings indicate that mtDNA-CN is a complex biomarker reflecting specific MT processes related to mtDNA regulation, and that these processes are causally related to human diseases.

Congenital cataract, an ocular disease predominantly occurring within the first decade of life, is one of the leading causes of blindness in children. However, the molecular mechanisms underlying the pathogenesis of congenital cataract remain incompletely defined. Through whole-exome sequencing of a Chinese family with congenital cataract, we identified a potential pathological variant (p.G1943E) in PIKFYVE, which is located in the PIP kinase domain of the PIKFYVE protein. We demonstrated that heterozygous/homozygous disruption of PIKFYVE kinase domain, instead of overexpression of PIKFYVEG1943E in zebrafish mimicked the cataract defect in human patients, suggesting that haploinsufficiency, rather than dominant-negative inhibition of PIKFYVE activity caused the disease. Phenotypical analysis of pikfyve zebrafish mutants revealed that loss of Pikfyve caused aberrant vacuolation (accumulation of Rab7+Lc3+ amphisomes) in lens cells, which was significantly alleviated by treatment with the V-ATPase inhibitor bafilomycin A1 (Baf-A1). Collectively, we identified PIKFYVE as a novel causative gene for congenital cataract and pinpointed the potential application of Baf-A1 for the treatment of congenital cataract caused by PIKFYVE deficiency.

Protein biomarkers have been identified across many age-related morbidities. However, characterising epigenetic influences could further inform disease predictions. Here, we leverage epigenome-wide data to study links between the DNA methylation (DNAm) signatures of the circulating proteome and incident diseases. Using data from four cohorts, we trained and tested epigenetic scores (EpiScores) for 953 plasma proteins, identifying 109 scores that explained between 1% and 58% of the variance in protein levels after adjusting for known protein quantitative trait loci (pQTL) genetic effects. By projecting these EpiScores into an independent sample (Generation Scotland; n = 9537) and relating them to incident morbidities over a follow-up of 14 years, we uncovered 130 EpiScore-disease associations. These associations were largely independent of immune cell proportions, common lifestyle and health factors, and biological aging. Notably, we found that our diabetes-associated EpiScores highlighted previous top biomarker associations from proteome-wide assessments of diabetes. These EpiScores for protein levels can therefore be a valuable resource for disease prediction and risk stratification.
RNA-seq and phytohormone analysis reveals the culm color variation of Bambusa oldhamii Munro

Published: January 2022

Background

The clumping bamboo Bambusa oldhamii Munro, known as “green bamboo”, is famous for its edible bamboo shoots and fast-growing timber. The green and yellow striped-culm B. oldhamii variety, named B. oldhamii f. revoluta W.T. Lin & J. Y. Lin, is an attractive system for researching the culm color variation of B. oldhamii.

Methods

Millions of clean reads were generated and assembled into 604,900 transcripts, and 383,278 unigenes were acquired with RNA-seq technology. The quantification of ABA, IAA, JA, GA1, GA3, GA4, and GA7 was performed using HPLC–MS/MS platforms.

Results

Differential expression analysis showed that 449 unigenes were differentially expressed genes (DEGs), among which 190 DEGs were downregulated and 259 DEGs were upregulated in B. oldhamii f. revoluta. Phytohormone contents, especially GA1 and GA7, were higher in B. oldhamii. Approximately 21 transcription factors (TFs) were differentially expressed between the two groups: the bZIP, MYB, and NF-YA transcription factor families had the most DEGs, indicating that those TFs play important roles in B. oldhamii culm color variation. RNA-seq data were confirmed by quantitative RT-PCR analysis of the selected genes; moreover, phytohormone contents, especially those of ABA, GA1 and GA7, were differentially accumulated between the groups. Our study provides a basal gene expression and phytohormone analysis of B. oldhamii culm color variation, which could provide a solid fundamental theory for investigating bamboo culm color variation.

Published: January 2022

Waste Management can be quite challenging, especially in the developing world. The challenge becomes even more complex with the growing population. City planners and decision makers are turning to technology to improve the efficiency of the waste management process. Geospatial technologies have offered a range of solutions, which have been deployed with success in waste management. This paper highlights the challenges of waste management in Port Harcourt, Nigeria, and how the Rivers State Waste Management Agency (RIWAMA) deployed the use of GIS in solving most of the challenges of identification, planning, evacuation, and transportation of wastes within the Port Harcourt metropolis. This paper looked at how this solution was deployed to solve key challenges as well as stimulate citizen participation in the waste management process. The paper concludes with a set of recommendations for expanding the potentials of its application.
