description: Many new physics models contain a neutral scalar resonance that can be predominantly produced via gluon fusion through loops. In such a case, there could be important effects of additional particles, that in turn may hadronize before decaying and form bound states. This interesting possibility may lead to novel signatures with double peaks that can be searched for at the LHC. We study the phenomenology of double peak searches in diboson final states from loop induced production and decay of a new neutral spin-0 resonance at the LHC. The loop-induced couplings should be mediated by particles carrying color and electroweak charge that after forming bound states will induce a second peak in the diboson invariant mass spectrum near twice their mass. A second peak could be present via loop-induced couplings into $gg$ (dijet), $γγ$ and $Zγ$ final states as well as in the $WW$ and $ZZ$ channels for the case of a pseudo-scalar resonance or for scalars with suppressed tree-level coupling to gauge bosons.

Gravity at cosmological distances: Explaining the accelerating expansion without dark energy
Creators: name: Harada, Junpei
Publisher: name: arXiv

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Three theoretical criteria for gravitational theories beyond general relativity are considered: obtaining the cosmological constant as an integration constant, deriving the energy conservation law as a consequence of the field equations, rather than assuming it, and not necessarily considering conformally flat metrics as vacuum solutions. Existing theories, including general relativity, do not simultaneously fulfill all three criteria. To address this, a new gravitational field equation is proposed that satisfies these criteria. From this equation, a spherically symmetric exact solution is derived, which is a generalization of the Schwarzschild solution. It incorporates three terms: the Schwarzschild term, the de Sitter term, and a newly discovered term, which is proportional to $r^4$ in a radial coordinate, that becomes significant only at large distances. The equation is further applied to cosmology, deriving an equation for the scale factor. It then presents a solution that describes the transition from decelerating to accelerating expansion in a matter-dominated universe. This is achieved without the need for negative pressure as dark energy or the positive cosmological constant. This provides a novel explanation for the current accelerating expansion of the universe.

description: Because of a perceived (and real) risk of repressive action, some survey questions are sensitive in more autocratic countries while less so in more democratic countries. Yet, survey data on potentially sensitive topics are frequently used in comparative research despite concerns about comparability. To examine the comparability of politically sensitive questions, I employ a multilevel analysis with more than 228,000 respondents in 37 African countries to test for systematic bias when the survey respondents believe (fear) that the government, rather than an independent research institute, has commissioned the survey. The findings indicate that fear of the government induces a substantial and significant bias on questions regarding trust, approval and corruption perceptions in more autocratic countries, but not in more democratic countries. In contrast, innocuous, apolitical questions are not systematically influenced by regime type.
An Assessment of Woreda Capacity: the Case of Gindeberet and Abuna Gindeberet Woredas in Oromia National Regional State
Creators: name: Fekadu, Telaye

Year: 2012

description: This research assesses woreda capacity in Gindeberet and Abuna Gindeberet Woreda of West Shoa Zone Oromia National Regional State since the implementation of District Level Decentralization Program. To this end, the research has assessed the human resource, financial, managerial, facility capacity as well as the extent to which enabling work environment and community participation is available. In order to achieve these objectives, qualitative and quantitative research approaches were used. Furthermore, to generate qualitative and quantitative data primary and secondary sources were employed. Key informant interview, questionnaires, and focus group discussions were used as primary sources whereas financial and human resource reports and other relevant documents were used as secondary sources. Both probability and non-probability sampling techniques were employed. The finding of the study indicated that the capacity building program which was launched to address the problem of rural woredas has not brought about significant changes or could not bring about the desired change though there are some improvements in terms of community participation, service delivery and responsiveness to customers. It has also empowered woreda civil servants to provide decisions on their own. However, constraints of resources and its utilization, lack of conducive work condition, lack of strong political leadership and commitment, and lack of governance system have been identified as factors responsible for the ineffectiveness of the program. Accordingly, the study found out among other things, problem of adequate and competent human resources as well as lack of managerial capacity. Furthermore, woredas have limited financial and human resource autonomy as well as lack autonomy to set priority and targets. Besides, low revenue generating capacity has forced woredas to heavily rely on block grant from the regional government. Moreover, the overall work environment was not conducive and attractive as inter alia organizational structures were unclear, unstable and complex as well as there was weak coordination and communication among local governance actors. The level of the participation of the community in matters affecting their life was found not to the desired level. It is therefore, generally recommended that for the capacity building effort to be materialized and achieve the desired objectives, there is a need to fulfill the following conditions that enhances the successful implementation of the program, viz. availability of resources and proper utilization, strong political leadership and commitment, enabling work environment and the governance system has to be improved

description: We study the intrinsic spin Hall effect of a Dirac Hamiltonian system with ferromagnetic exchange coupling, a minimal model combining relativistic spin-orbit interaction and ferromagnetism. The energy bands of the Dirac Hamiltonian are split after introducing a Stoner-type ferromagnetic ordering which breaks the spherical symmetry of pristine Dirac model. The totally antisymmetric spin Hall conductivity (SHC) tensor becomes axially anisotropic along the direction of external electric field. Interestingly, the anisotropy does not vanish in the asymptotic limit of zero magnetization. We show that the ferromagnetic ordering breaks the spin degeneracy of the eigenfunctions and modifies the selection rules of the interband transitions for the intrinsic spin Hall effect. The difference in the selection rule between the pristine and the ferromagnetic Dirac phases causes the anisotropy of the SHC, resulting in a discontinuity of the SHC as the magnetization, directed orthogonal to the electric field, is reduced to zero in the ferromagnetic Dirac phase and enters the pristine Dirac phase.

title: A Phenomenographic Study on On-reserve First Nations, Metis and Inuit Students' Experiences in a One-year College Transition Programme
Creators: name: Condappa, Charmaine
Publisher: name: University of Liverpool Repository
Year: 2019

description: In an age when access to higher education is expanding, the literature shows that First Nations, Métis, and Inuit (FNMI) students are underrepresented. Those who manage to enter university experience challenges that hinder their success. Consequently, transitional programmes have been set up to support FNMI students as they move from high school to higher education institutions. To better understand the challenges of transitioning, I decided to embark on a phenomenographic study that explores six on-reserve Canadian FNMI students’ conceptions of their learning experiences in their community college. In addition, the study also examines two of their teachers’ perceptions of the students’ experiences as they prepared them for university. The findings show that some students adopted approaches to learning that do not define or characterize who they are as learners, but instead reflect how they coped with teaching and learning in their environment. These approaches, conceptualised in phenomenography as surface and deep approaches, are not truly the way that FNMIs are as learners. Surface and deep approaches do not mirror the cultural perspectives and holistic experiences evident in an indigenous view of learning. The surface approach (learning as primarily reproductive) refers to those who see learning as based on that, which is extrinsic to the real purpose of the task. By contrast, the deep approach (learning as primarily seeking meaning) is associated with students’ intentions to understand and engage in meaningful learning, focusing on principles, and using strategies that are appropriate for creating meaning.

Peygamber’in Hayatına Dair Stratejik ve Siyasî Bir Okuma” ismiyle kazandırılan çalışmadır. Eserde Hz. Peygamber’in hayatı siyasi ve stratejik açıdan değerlendirilerek onun evrensel misyonu ve nebevi liderliğinin günümüz Müslümanları için örneklik oluşturabilme imkânları ortaya konmaya çalışılmıştır. Modern dönemde Müslüman toplumlar ağır bir sosyal, kültürel ve ekonomik bunalım içerisinde bulunuyorlar. Bunun nedeni de derin bir epistemolojik kriz yaşamalarıdır. Bunu aşmanın bir yolu da Hz. Peygamber’in hayatını yücelterek ve sıradanlaştırarak değil, onun yaşamını modern bilgi ve tecrübelerden de yararlanarak yeniden okumaktan geçmektedir. Bunu da taklidin esaretinden kurtulmuş, sorunların zamanın değişmesinden değil, zihinlerin tembelliğinden kaynaklandığını idrak eden özgür bilinçler yapacaktır. Bu bilinç; hayata anlam ve misyon kazandıran ahlâkî ve varoluşsal gayelere sahip, kendinden emin ve dengeli bir benliktir.

description: We study the winding number susceptibility < I^2> in a superfluid system and the topological susceptibility < Q^2> in QCD. We argue that both correlation functions exhibit similar structures, including the generation of the contact terms. We discuss the nature of the contact term in superfluid system and argue that it has exactly the same origin as in QCD, and it is related to the long distance physics which cannot be associated with conventional microscopical degrees of freedom such as phonons and rotons. We emphasize that the conceptual similarities between superfluid system and QCD may lead, hopefully, to a deeper understanding of the topological features of a superfluid system as well as the QCD vacuum.

description: The origin of rapid rotation in massive stars remains debated, although binary interactions are now often advocated as a cause. However, the broad and shallow lines in the spectra of fast rotators make direct detection of binarity difficult. In this paper, we report on the discovery and analysis of multiplicity for three fast-rotating massive stars: HD25631 (B3V), HD191495 (B0V), and HD46485 (O7V). They display strikingly similar TESS light curves, with two narrow eclipses superimposed on a sinusoidal variation due to reflection effects. We complement these photometric data by spectroscopy from various instruments (X-Shooter, Espadons, FUSE...), to further constrain the nature of these systems. The detailed analyses of these data demonstrates that the companions of the massive OB stars have low masses (~1Msol) with rather large radii (2-4 Rsol) and low temperatures (<15 kK). These companions display no UV signature, which would exclude a hot subdwarf nature, but disentangling of the large set of X-Shooter spectra of HD25631 revealed the typical signature of chromospheric activity in the companion's spectrum. In addition, despite the short orbital periods (P=3-7d), the fast-rotating OB-stars still display non-synchronized rotation and all systems appear young (<20Myr). This suggests that, as in a few other cases, these massive stars are paired in those systems with non-degenerate, low-mass PMS companions, implying that fast rotation would not be a consequence of a past binary interactions in their case.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Review of literature shows that the consumption of bottled water is increasing all over the world, especially in the developing economies, the increment is more substantial. Research results also show that the factors that influence the consumers' buying behavior of bottled water varies culturally and geographically. Consequently, the objective of the current study is to examine the factors behind customer consumption behavior of bottled water and to understand how they make their choices among the many brands available. The current study employed quantitative research approach and utilized correlational and descriptive research design and cross-sectional survey method of data collection using a self-report questionnaire. The participants (n = 171) of the study are residents of Addis Ababa and were selected using convenience sampling technique. The Statistical Package for Social Sciences Software has been employed for data analysis using statistical techniques such as descriptive statistics, t-test, ANOVA, Pearson's correlation and linear hierarchical regression. Bivariate correlation analysis indicated that occupation, belief, convenience, HQ, price and EKAS have statistically significant relationship with CB of respondents. Variance analysis of consumption behavior of BW against the categories of demographic variables (gender, season, age, education, occupation and monthly income) showed no significant variances were retained. Hierarchical regression analysis showed that the factors that predict the consumption behavior of BW are occupational background, price, packaging designs and EKAS with statistical significance of p = 0.05. Despite some limitations in the sampling and data collection processes, the result might provide practical and theoretical experience to the existing knowledge of consumption behavior of bottled water as well as other similar products.
Why are Quasiperiodic Eruptions only Found in Low-Mass Galaxies?

Publisher: name: arXiv
Year: 2023
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: I consider the current sample of galaxy nuclei producing quasiperiodic eruptions (QPEs). If the quasiperiod results from the orbital motion of a star around the central black hole, the dearth of associated black hole masses $\gtrsim 10^6\msun$ places tight constraints on models. It disfavours those assuming wide orbits and small eccentricities, because there is ample volume within pericentre to allow significantly more massive holes in QPE systems than are currently observed. If instead the orbiting star is assumed to pass close to the black hole, the same lack of large black hole masses strongly suggests that the stellar orbits must be significantly eccentric, with $1 - e \lesssim {\rm few}\times 10^{-2}$. This favours a tidal disruption near-miss picture where QPEs result from repeated accretion from an orbiting star (in practice a white dwarf) losing orbital angular momentum to gravitational radiation, even though this is not assumed in deriving the eccentricity constraint. Given the tight constraints resulting from the current small observed sample, attempts to find QPE systems in more massive galaxies are clearly important.

description: The second-order phase transition into a hidden order phase in URu$_2$Si$_2$ goes along with an order parameter which is still a mystery, despite 30 years of research. However, it is understood that the symmetry of the order parameter must be related to the symmetry of the low lying local electronic $f$-states. Here we present results of a novel spectroscopy, namely core-level non-resonant inelastic x-ray scattering (NIXS). This method allows for the measurement of local high-multipole excitations and it is bulk sensitive. The observed anisotropy of the scattering function unambiguously shows that the 5$f$ ground state wave function is composed mainly, but essentially not purely, of the $Γ_1$ with majority $J_z$ =$|4\rangle$ + $|-4\rangle$ and/or $Γ_2$ singlet states.

description: Combinatory logic synthesis is a new type-based approach towards automatic synthesis of software from components in a repository. In this thesis we show how the type-based approach can naturally be used to exploit taxonomic conceptual structures in software architectures and component repositories to enable automatic composition and configuration of components, and also code generation, by associating taxonomic concepts to architectural building blocks such as, in particular, software connectors. Components of a repository are exposed for synthesis as typed combinators, where intersection types are used to represent concepts that specify intended usage and functionality of a component. An algorithm for solving the type inhabitation problem in combinatory logic - does there exist a composition of combinators with a given type? - is then used to automate the retrieval, composition, and configuration of suitable building blocks with respect to a goal specification. Since type inhabitation has high computational complexity, heuristic optimizations for the inhabitation algorithm are essential for making the approach practical. We discuss particularly important (theoretical and pragmatic) optimization strategies and evaluate them by experiments. Furthermore, we apply this synthesis approach to define a method for software connector synthesis for realistic software architectures based on a type theoretic model. We conduct experiments with a rapid prototyping tool that employs this method on complex concrete ERP- and e-Commerce-systems and discuss the results.

description: This paper investigates the geometry of compact stellar objects via Noether symmetry strategy in the framework of curvature-matter coupled gravity. For this purpose, we assume the specific model of this theory to evaluate Noether equations, symmetry generators and corresponding conserved parameters. We use conserved parameters to examine some fascinating attributes of the compact objects for suitable values of the model parameters. It is analyzed that compact objects in this theory depend on the conserved quantities and model parameters. We find that the obtained solutions provide the viability of this process as they are compatible with the astrophysical data.

description: Astrophysical searches for gamma rays are one of the main strategies to probe the annihilation or decay of dark matter particles. We present a new class of distinct sub-GeV spectral features that generically appear in kinematical situations where the available center-of-mass energy in such processes is just above threshold to produce excited meson states. Using a Fisher forecast with realistic astrophysical backgrounds, we demonstrate that for upcoming experiments like e-ASTROGAM and ComPair these signals can turn out to be the smoking gun in the search for particle dark matter.

description: Die Dissertation entstand im Rahmen der Wissenschaftlichen Flankierung des TransKiGs-Projekts , das zur Optimierung des Übergangs vom Elementar- in den Primarbereich in insgesamt 5 Bundesländern etabliert wurde, und beinhaltete folgende Ziele: 1. Die Entwicklung und Validierung eines Beobachtungsinstruments zur Erfassung bereichsübergreifender sowie bereichsspezifischer Prozessqualitätsaspekte, das sowohl für den Elementar- als auch den Primarbereich normiert ist (Transitionsinstrument). 2. Auf Basis der im Rahmen der Entwicklung und Validierung des Instrumentes erfassten Ergebnisse einen Einblick in die institutionenspezifische Prozessqualität von Kindertageseinrichtungen und Grundschulen zu ermöglichen, um mögliche Gemeinsamkeiten und Unterschiede sichtbar zu machen und Ansatzpunkte für (gemeinsame) Fort- und Weiterbildungsmaßnahmen aufzuzeigen. 3. Das Instrument als Orientierungshilfe zur Strukturierung und Systematisierung von Reflexionsprozessen für Praktikerinnen handhabbar und nutzbar zu machen, damit es als Selbst- und Teamqualifizierungstool dienen kann. Als Grundlage für die Entwicklung des Instrumentes diente ein bereits für den Elementarbereich validiertes Beobachtungsverfahren mit dem bereichsübergreifende und sprachförderrelevante Prozessqualitätsaspekte erfasst werden können (DO-RESI). Dieses Verfahren wurde an den Primarbereich kontextspezifisch adaptiert, sowie um Items ergänzt, die zusätzlich die Förderrelevanz in Bezug auf die Bildungsbereiche Mathematik und Naturwissenschaft zu erfassen vermögen (DO-RESI-E-KiGs). Die messmethodische Überprüfung des so entwickelten Verfahrens ergab, dass das Transitionsinstrument sowohl im Elementar- als auch im Primarbereich die förderrelevante Prozessqualität hinreichend objektiv, reliabel und valide misst. Die mit dem Instrument erfasste Prozessqualität zeigte für die an TransKiGs beteiligten Kindertageseinrichtungen und Grundschulen ein relativ ähnliches Bild, wobei für beide Institutionen mittelmäßige bis gute bereichsübergreifende Werte, dagegen aber eher minimale bis mittelmäßige Ergebnisse in Bezug auf die bereichsspezifische Prozessqualität festgestellt werden konnte. Daran anknüpfend wurden im Rahmen der Dissertation erste Schritte unternommen, um das Transitionsinstrument DO-RESI-E-KiGs für Pädagoginnen als Selbst- und Teamqualifizierungstool zur eigenständigen Reflexion förderrelevanter Situationen nutzbar zu machen.

description: We study shared multi-processor scheduling problem where each job can be executed on its private processor and simultaneously on one of many processors shared by all jobs in order to reduce the job's completion time due to processing time overlap. The total weighted overlap of all jobs is to be maximized. The problem models subcontracting scheduling in supply chains and divisible load scheduling in computing. We show that synchronized schedules that complete each job at the same time on its private processor and shared processors, if any is actually used by the job, include optimal schedules. We prove that the problem is NP-hard in the strong sense for jobs with arbitrary weights, and we give an efficient, polynomial-time algorithm for the problem with equal weights.
The Role of Decentralization in Education and Health Services Delivery in Addis Ababa City Government: Evidence from the Case of Yeka-Sub City
Creators: name: Daresema, Abenet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Decentralized service delivery refers to the mode in which service delivery is done through delegation and devolution of power from center to local governments whereby efficiency and effectiveness are likely to be achieved. The purpose of this study was to assess the improvements in education and health services delivery in Yeka sub city of Addis Ababa city government. To realize the purpose of the study, case study research method was conducted. The study is qualitative whereby simple quantitative tools were employed so as to complement the qualitative narrations. The study primarily utilized secondary data obtained, from policy documents, constitution, proclamations, intervention plans and performance reports, etc. The study was supported with primary data obtained through interviews and questionnaires. The data results revealed that there is achievement in health and education service delivery as well as there are gaps in the services delivered. The findings of the study revealed that various functions of education and health services have been devolved to the lowest tier of government. The study has indicated that there are multiple bodies established at lower levels of government to support school and health centers activities. As a result, the services provided have expanded; there is now an increased availability and accessibility of the services in both education and health. The study also observed constraints; the constraints consider human resource, finance and facilities . Key Words concepts: service delivery, education & health, decentralization

description: The highly variable blazar OJ~287 is commonly discussed as an example of a binary black hole system. The 130 year long optical light curve is well explained by a model where the central body is a massive black hole of 18.35$\times$10$^9$ solar mass that supports a thin accretion disc. The secondary black hole of 0.15$\times$10$^9$ solar mass impacts the disc twice during its 12 year orbit, and causes observable flares. Recently, it has been argued that an accretion disc with a typical AGN accretion rate and above mentioned central body mass should be at least six magnitudes brighter than OJ~287's host galaxy and would therefore be observationally excluded. Based on the observations of OJ~287's radio jet, detailed in Marscher and Jorstad (2011), and up-to-date accretion disc models of Azadi et al. (2022), we show that the V-band magnitude of the accretion disc is unlikely to exceed the host galaxy brightness by more than one magnitude, and could well be fainter than the host. This is because accretion power is necessary to launch the jet as well as to create electromagnetic radiation, distributed across many wavelengths, and not concentrated especially on the optical V-band. Further, we note that the claimed V-band concentration of accretion power leads to serious problems while interpreting observations of other Active Galactic Nuclei. Therefore, we infer that the mass of the primary black hole and its accretion rate do not need to be smaller than what is determined in the standard model for OJ~287.

description: T-2 toxin and HT-2 toxin are mycotoxins which belong to the large group of fungal sesquiterpenes, commonly denoted as trichothecenes. They are produced by various Fusarium species. Generally, the Fusarium species invade crops under moist and cool conditions. T-2 toxin and HT-2 toxin and other trichothecenes are found in cereal grains and cereal grains products. In 2011, EFSA published a Scientific Opinion on the risks to animal and human health related to the presence of T-2 and HT-2 toxins in food and feed. Based on EFSA's opinion, the European Commission has made recommendations on indicative levels of T-2 and HT-2 toxins in cereal grains and cereal grain products intended for use as food and feed, and further needed action (Commission Recommendation 2013/165/EU). The European Commission has recommended Member States to collect reliable data on different annual levels of T-2 and HT2 toxins in order to establish a maximum level (ML) for different types of food and feed. In addition, it is recommended to gather information on various factors (weather conditions, food processing, applied agrotechnical measures) that affect high concentrations of T-2 and HT-2 toxins in cereal grains and cereal grain products in order to determine the measures needed to avoid or reduce presence of T-2 and HT-2 toxins in the products. Therefore, the Scientific Panel for Chemical Hazards who acted at Croatian Food Agency (now Croatian Agency for Agriculture and Food - HAPIH) proposed a three-year study about occurrence of T-2 and HT-2 toxins in cereals produced in the Republic of Croatia. The study was conducted in period 2017 – 2019. In that period impact of weather conditions on occurrence of T-2 and HT-2 toxins was analyzed. The results of this research were used in the preparation of this scientific report.

description: We successfully synthesized polycrystalline LK-99-like ceramic samples with a solid-state-sintering method. Powder X-ray diffraction shows that the main contents are $\mathrm{Pb_{10-x}Cu_x(PO_4)_6O}$ and $\mathrm{Cu_2S}$, consistent with recent reports [arXiv:2307.12037; arXiv:2308.01192]. In some small flaky fragments, we successfully observed ``half levitation'' atop a $\mathrm{Nd_2Fe_{14}B}$ magnet. Using magnetization measurements on such small pieces, as well as on a large piece which does not exhibit the half levitation, we show that the samples ubiquitously contain weak yet definitive soft ferromagnetic components. We argue that, together with the pronounced shape anisotropy of the small fragments, the soft ferromagnetism is sufficient to explain the observed half levitation in strong vertical magnetic fields. Our measurements do not indicate the presence of the Meissner effect, nor zero resistance, in our samples, leading us to believe that our samples do not exhibit superconductivity. The precise chemical composition and the physics behind the ferromagnetic component remain outstanding questions to be addressed in future research.

title: AUTHENTIC LEADERSHIP IN NATO: AN ACTION RESEARCH STUDY
Creators: name: Hargreaves, G
Publisher: name: University of Liverpool Repository
Year: 2018

description: The study reveals a dissonance between the assessments of leadership experiences as reported by staff in the same organisation yet separated by only one managerial layer. It highlights the challenges and tensions felt as the leaders became aware of the dissonance and describes an organisational alignment initiative aimed at improving the coherence between the leadership and the organisational culture within a multinational military setting. The story reveals how leadership is often affected through previous experiences, experiences that were contextually unique, dated, fulfilling and effective at that time, yet potentially limiting and perhaps only partially effective in their current multinational leadership role. This reveals how insights and research were combined to create the catalyst for individual and organisational learning; it describes how personal development interventions were carefully crafted in order to specifically appeal to senior multinational leaders and managers. These leaders and managers were asked to confront and articulate their own values and beliefs about leadership and, in some cases, modify them in light of new learning; to become even more authentic leaders. Cognizant through academic research that leadership and organisational cultures can have a profound effect on performance (Denison and Mishra, 1995: Harris and Ogbonna, 2000), aware through staff feedback and an organisational change that will be described in detail I was deeply curious to try and discover “did the way in which leadership is practised change in some way as a consequence of the organisational culture awareness activities?

description: We present the first results from the largest H$α$ survey of star formation and AGN activity in galaxy clusters. Using 9 different narrow band filters, we select $>3000$ H$α$ emitters within $19$ clusters and their larger scale environment over a total volume of $1.3\times10^5$ Mpc$^3$. The sample includes both relaxed and merging clusters, covering the $0.15-0.31$ redshift range and spanning from $5\times10^{14}$ $M_{\odot}$ to $30\times10^{14}$ $M_{\odot}$. We find that the H$α$ luminosity function (LF) for merging clusters has a higher characteristic density $ϕ^*$ compared to relaxed clusters. $ϕ^*$ drops from cluster core to cluster outskirts for both merging and relaxed clusters, with the merging cluster values $\sim0.3$ dex higher at each projected radius. The characteristic luminosity $L^*$ drops over the $0.5-2.0$ Mpc distance from the cluster centre for merging clusters and increases for relaxed objects. Among disturbed objects, clusters hosting large-scale shock waves (traced by radio relics) are overdense in H$α$ emitters compared to those with turbulence in their intra-cluster medium (traced by radio haloes). We speculate that the increase in star formation activity in disturbed, young, massive galaxy clusters can be triggered by interactions between gas-rich galaxies, shocks and/or the intra-cluster medium, as well as accretion of filaments and galaxy groups. Our results indicate that disturbed clusters represent vastly different environments for galaxy evolution compared to relaxed clusters or average field environments.
