The Role of Myths in Shaping Cultural Values

The Role of Myths in Shaping Cultural Values

Myths play a vital role in shaping the cultural values of societies by providing frameworks for understanding the world, establishing moral codes, and reinforcing social norms. Through narratives, rituals, and shared experiences, myths convey the beliefs, values, and ideals that define various cultures.

Explanation and Frameworks

At their core, myths serve as explanations for natural phenomena and social customs, offering narratives that codify collective memories and wisdom passed through generations. For instance, as highlighted in various sources, myths help explain essential life questions, such as creation, existence, morality, and the human experience, thus providing a meaningful framework through which societies understand their reality[1][3][7]. The imaginative power of myths makes them memorable, crystallizing complex ideas into enduring narratives.

Moreover, myths articulate ethical values and societal norms. For example, the Greek myths reflect notions of heroism, morality, and the human condition, establishing standards of behavior for individuals within the society[2][4]. The archetypal characters in these stories often exemplify virtues like bravery and wisdom, serving as models for personal conduct[9]. Consequently, individuals are influenced by these narratives, navigating their lives with guidance from the ideals represented within the myths.

Reinforcement of Social Norms

Myths also play a significant role in justifying and legitimizing social norms and hierarchies. Many cultures have creation myths that link their legal and social structures to divine origins, thereby granting authority to their laws and customs. For instance, ancient legal systems often posited that their laws were divinely ordained, with myths validating their existence[7][8]. This connection between myth and law fosters a sense of order and stability, reinforcing communal beliefs and practices that shape everyday life.

In addition to upholding social order, myths can also reflect and respond to societal changes. As societies evolve, myths often adapt, incorporating contemporary issues and concerns while retaining their foundational narratives. This evolution illustrates how myths not only resonate with the cultural context of their time but also actively shape cultural values by reflecting the aspirations, fears, and moral dilemmas of the society[5][8].

Cultural Heritage and Collective Identity

The transmission of myths through oral and written traditions plays a crucial role in preserving cultural heritage. By recounting these stories, societies maintain a link to their past, fostering a sense of identity and continuity[3][8]. Myths serve as vessels for cultural memories, helping individuals understand their origins and place within a larger narrative. They create an 'us versus them' mentality that can unify members of a community while simultaneously distinguishing one culture from another[8].

Furthermore, the themes prevalent in myths often express the collective psyche of a culture, reflecting societal values and interpersonal relationships. The narratives encapsulate what a society holds dear and warn against vices that threaten communal harmony, thus aligning individual behavior with collective expectations[2][4][9]. By engaging with these myths, individuals cultivate a personal identity intertwined with their cultural values and heritage.

Moral Guidance and Educational Value

Myths frequently provide moral guidance, offering cautionary tales that highlight the consequences of certain behaviors. These stories emphasize the importance of virtues while cautioning against hubris, greed, and other vices. They function as a moral compass for societies, illustrating behaviors to emulate or avoid[3][8]. For example, in many myths, heroic figures endure trials that test their virtues, reinforcing the idea that personal growth is often achieved through overcoming challenges.

Moreover, myths have a valuable educational aspect, as they encapsulate the knowledge and beliefs of a culture in narrative form. They serve as a means of instruction, imparting lessons about life and existence and ensuring that cultural values are transmitted to future generations[6][7]. The integration of moral lessons within myths ensures that they remain relevant, adapting to contemporary values while retaining their historical significance.

Conclusion

In conclusion, myths are a fundamental element in shaping cultural values, providing a narrative framework that explains existence, establishes moral codes, and reinforces societal norms. They serve as a bridge between past and present, uniting communities through shared stories and collective identities. By studying myths, we gain insight into the complexities of human experience and the enduring ideals that shape cultures across time and space. Thus, the influence of myths continues to resonate in contemporary society, reminding us of the profound ways in which these narratives guide and reflect our values and beliefs.

What are fiscal policies?

 title: 'All About Fiscal Policy: What It Is, Why It Matters, and Examples'

Fiscal policies are governmental strategies involving the use of spending and taxation to influence the economy. These policies are primarily implemented to manage economic activity, particularly during times of recession or inflation. Governments employ fiscal policy to achieve economic goals such as promoting growth, reducing unemployment, and controlling inflation.

Key components of fiscal policy include adjusting tax rates and government spending levels. For example, during a recession, the government may lower taxes and increase spending to stimulate demand and economic activity. Conversely, in times of inflation, it may raise taxes or reduce spending to cool down an overheated economy[1][2][4][5][6].

Fiscal policy was significantly shaped by the ideas of economist John Maynard Keynes, who advocated for countercyclical approaches. He believed that government intervention could stabilize the economy by influencing aggregate demand through fiscal measures. This approach encourages deficit spending during downturns and surpluses during periods of growth[1][5][6].

Governments can utilize mandatory spending (such as Social Security), discretionary spending (like defense), and supplemental spending for urgent budget needs as part of their fiscal policy framework. Additionally, fiscal policy can be classified into expansionary or contractionary types, where expansionary policy aims to boost the economy, while contractionary policy seeks to reduce spending and increase taxes to combat inflation[2][3].

In summary, fiscal policies serve as vital tools for governments to maintain economic stability and promote sustainable growth[4][5][6].

How should governments build evaluation into the policy cycle?. Synthesize the recurring design principles for evaluation systems: ex ante planning, ex post review, proportional methods, stakeholder engagement, data governance, central support, and decision links. Include a practical checklist for analysts distinguishing a credible evaluation system from a compliance exercise.

Embedding evaluation throughout the policy cycle

The WHO and OECD sources converge on a simple test: evaluation should be built in from the start, carried through implementation, and then used again in later decisions, rather than treated as a one-off compliance product.[1][2]

  • Plan early and fund it. WHO calls for evaluation to be planned within the planning and budgeting cycle, with workplans and budgets identified from the outset; OECD likewise places evaluation at the inception stage through ex ante assessment.[3][4]
  • Review after implementation. OECD emphasizes monitoring, data collection, indicators, and ex post evaluation, while WHO expects findings to trigger management responses and follow-up.[5][6]
  • Use methods proportionate to the question. OECD says methods should fit the significance of the policy or regulation, and WHO describes its framework as flexible rather than fixed to one method.[7][8]
  • Engage stakeholders without compromising independence. WHO allows management-group review while preserving the evaluation team's independence, and OECD treats consultation as a way to strengthen evidence and use.[9][10]

What distinguishes a credible system from a compliance exercise

A credible system is not defined by the existence of reports alone. It is credible when evaluation is routine, proportionate, coordinated, data-informed, and visibly linked to decisions.[11][12]

  • It has a real ex ante and ex post loop, not just an end-of-cycle report.[13][14]
  • It matches analytical effort to policy significance, rather than applying the same template everywhere.[15][16]
  • It protects evaluation independence while still requiring structured stakeholder input and transparent review.[17][18]
  • It can access and share relevant data through workable governance arrangements.[19][20]
  • It has central coordination, technical guidance, and quality assurance, not just fragmented unit-level activity.[21][22]
  • It drives management, budget, or regulatory decisions through explicit follow-up and dissemination.[23][24][25]

Practical checklist for analysts

CheckWhat to look for
1. Ex ante planningIs evaluation built into planning and budgeting, with clear workplans or assessment requirements before implementation starts?[26][27]
2. Ex post reviewAre monitoring, indicators, and post-implementation evaluation required, with a management response or follow-up process?[28][29]
3. Proportionate methodsAre methods tailored to the importance and complexity of the policy question, rather than applied mechanically?[30][31]
4. Stakeholder engagementDo stakeholders contribute evidence and use, while the evaluators retain independence?[32][33]
5. Data governanceAre data production, access, sharing, and collection planned early and governed well enough to support the evaluation?[34][35]
6. Central supportIs there a central function or oversight unit that provides guidance, quality assurance, and coordination?[36][37]
7. Decision linkageDo findings feed actual decisions, such as budget choices, regulatory review, management action, or dissemination requirements?[38][39][40]

If an evaluation system fails several of these checks, it is probably serving compliance more than learning or decision-making.[41][42]

Bottom line

Across WHO and OECD, the design principles are consistent: plan early, review later, use proportionate methods, involve stakeholders, secure data access and governance, provide central support, and make the link to decisions explicit.[43][44]

What are the main types of public transportation?

 title: 'Public transport - Wikipedia'

The main types of public transportation include buses, trolleybuses, trams, and trains. Buses operate on roads, while trolleybuses utilize electricity from overhead wires. Trams are railborne vehicles that run on tracks and are commonly found in urban areas. Trains operate on dedicated tracks and can cover longer distances quickly[1][6].

In addition to these, there are other forms such as subways (metro), light rail, and cable cars. Each of these modes serves different transit needs and urban structures, providing efficient alternatives to private vehicle use[2][4].

What did SEC oversight records say about the TCR program?. Structure the report around four sections: the OIG finding that the TCR program could be further strengthened, the planned analytics and automation system, audit planning activity, and known limits in report generation functionality. Include a source table with dates and a caveats section noting where the excerpts do not establish outcomes after the planned modernization.

SEC oversight records on the TCR program

The attached SEC oversight records point to four related themes: an OIG finding that the Tips, Complaints, and Referrals (TCR) program could be further strengthened, a planned modernization effort that would add analytics and automation, audit-planning work on the TCR intake and resolution system, and a functional distinction between storing data for reports and the application itself generating reports[1][2][3].

1) OIG finding: the TCR program could be further strengthened

The February 24, 2021 SEC OIG report is titled The SEC Can Further Strengthen the Tips, Complaints, and Referrals Program, which is the record supporting the finding that the TCR program could be further strengthened[4][5]. The excerpt available here does not include the full findings section, so the report title is the clearest evidence visible in the attached material[6].

2) Planned analytics and automation system

In the SEC's October 2022 Inspector General statement on management and performance challenges, the agency said that analytics and automation would be incorporated into the new TCR system[7]. The same excerpt says the agency was still assessing the application and data, conducting market research on potential technologies, and preparing a strategic plan, and it cites an SEC budget document dated March 28, 2022[8][9].

This portion of the record describes planning and modernization activity only. It does not establish what happened after the new system was implemented[10][11].

3) Audit planning activity

The SEC OIG document TCR System Audit Observations says the OIG contracted Williams, Adley & Company-DC, LLP to support engagement work intended to assist the OIG in planning an audit of the SEC's TCR intake and resolution system[12]. The excerpt does not show the final audit results, only that audit planning support work was underway[13].

Date visibility is limited in the provided excerpt, so the record can be described confidently as OIG audit-planning activity, but not dated more precisely from the excerpt alone[14].

4) Known limits in report-generation functionality

One SEC record makes a narrow functional point: it distinguishes between maintaining data that can be used to create reports and the TCR application actually creating reports[15][16]. In other words, the excerpt indicates that report-generation was not the application's role as described there, even though the data could support reports[17].

The excerpt does not say whether that limitation was later fixed, so it should be treated as a known limit in the record, not as proof of the system's final capability[18][19].

Caveats

These excerpts are enough to document the SEC's oversight record on the TCR program, but they do not establish outcomes after the planned modernization was completed[28][29]. They also leave some date and detail limits in place, especially for the audit-planning excerpt, where the provided text does not show a clear publication date[30].

The Women Quantum History Tried to Forget

Transcription

The early story of quantum physics is often told like it belonged to a few famous men, but women helped shape it from the start. H. Johanna van Leeuwen showed in her doctoral research that magnetism in solids could not be explained by classical physics alone. Laura Chalk Rowles later gave the earliest experimental test and the first confirmation of Schrödinger's wave mechanics predictions for hydrogen. Hertha Sponer became a major figure in quantum spectroscopy and molecular spectroscopy. Grete Hermann spotted an error in von Neumann's famous proof against hidden variables, long before that critique became widely known. And Sonja Ashauer completed a Cambridge thesis under Paul Dirac on electron self energy in quantum electrodynamics before her life was cut short. Their stories remind us that quantum history is not only a tale of celebrated geniuses. It is also a story of women whose work was real, important, and too often left in the shadows.

When does agency reorganization become a jurisdiction case?. Explain the USAID dismantling litigation through standing, redressability, Thunder Basin channeling, and the court's distinction between personnel related and grant related claims. Use a party by party table showing AFSA, AFGE, PSCA, and Oxfam, then map the review schemes identified in the memorandum opinion.

USAID dismantling litigation as a jurisdiction question

The memorandum opinion treats the case primarily as a jurisdiction problem: the court says it lacks subject-matter jurisdiction over AFSA’s, AFGE’s, and Oxfam’s claims, and likely lacks jurisdiction over PSCA’s claims, because the plaintiffs can show standing only for injuries tied to specific personnel or contract actions, not for a broad attack on the alleged dismantling of USAID as a whole.[1]

The key move in the opinion is to separate who is injured from what is being challenged. Personnel-related injuries may be justiciable for the employee and contractor organizations, but grant-related, website-related, and lease-related theories do not supply standing for the organizational plaintiffs, and Oxfam’s attempted third-party grantee theory also fails.[2][3][4]

Standing and redressability

For AFSA and AFGE, the court says standing exists only for personnel-related injuries affecting their members, because those are the injuries fairly traceable to the challenged conduct and capable of being redressed by relief aimed at those personnel actions.[5]

For PSCA, the court says standing is likely limited to claims tied to its members’ contract status and working conditions, not a broad claim about USAID’s alleged dismantling.[6]

Redressability follows the same line: the requested injunctions would not redress injuries if the real complaint is about employment or contract status, because the remedy must be tailored to the plaintiff’s own injury rather than to a generalized grievance about USAID as an institution.[7]

Oxfam cannot rely on injuries to USAID grantees, and its own resource-reallocation theory is either too indirect or too close to a self-manufactured mission setback to qualify as organizational standing.[8]

Thunder Basin channeling and the review schemes the court identified

The court then applies Thunder Basin-style channeling and says the personnel-related claims are likely funneled into existing statutory schemes rather than heard first in district court.[9]

PartyClaim type the court treats as potentially cognizableStanding / jurisdiction resultReview scheme identified
AFSAPersonnel-related claims tied to members’ employment status and working conditions[10][11]Standing only for those personnel-related injuries; broad dismantling theory rejected[12][13]CSRA, FSLMRS, and Foreign Service Act[14][15]
AFGEPersonnel-related claims tied to members’ employment status and working conditions[16][17]Standing only for those personnel-related injuries; broad dismantling theory rejected[18][19]CSRA, FSLMRS, and Foreign Service Act[20][21]
PSCAContract-related claims tied to members’ PSC contracts, status, and working conditions[22][23]Likely standing only for contract-status claims; broader USAID-dismantling claims not jurisdictionally available[24][25]Contract Disputes Act, with the ordinary contracting-officer / board-or-CFC path and then Federal Circuit review[26][27]
OxfamGrant-related theories based on USAID grant terminations and effects on its work and partners[28]No standing; third-party grantee injuries and indirect resource-reallocation theory both fail[29]No separate review scheme identified because Oxfam lacks standing[30][31]

In short, the opinion maps employee and contractor disputes into separate administrative review paths, but it does not send Oxfam’s grant-related theory anywhere because Oxfam never clears the standing threshold.[32][33][34]

Personnel-related versus grant-related claims

The court draws a sharp line between personnel-related claims and grant-related claims. Personnel-related claims arise from employment or contract relationships and are channeled through the relevant statutory schemes, while grant-related claims concern USAID grant terminations, website closures, and lease transfers, which do not establish standing for these plaintiffs.[35][36]

That distinction matters because it lets the court preserve the statutory review structure for employee and PSC disputes while still rejecting a broader attempt to transform a USAID funding dispute into an all-purpose challenge to agency dismantling.[37][38]

Bottom line

As framed by the memorandum opinion, the litigation is mostly jurisdictionally barred: AFSA and AFGE are limited to personnel claims, PSCA is limited to contract-based claims and likely routed through the CDA, and Oxfam lacks standing altogether.[39][40][41]

Quantum-safe blockchain design patterns. Explore architectural patterns such as hash-based signatures, lattice cryptography, and hybrid consensus mechanisms to future-proof blockchain networks. Include performance trade-offs and case studies.

Quantum-safe blockchain design patterns

The literature in the supplied set converges on four recurring quantum-safe blockchain patterns: hash-based signatures, lattice-based cryptography, migration-oriented retrofits for existing chains, and hybrid consensus or validation designs that co-design cryptography with consensus[1][2][3]. The evidence base is mostly surveys, prototypes, and model-driven studies rather than broad deployment reports, so the findings are best treated as design guidance and not as proof of production maturity[4][5].

Executive summary

Hash-based schemes appear in the surveys as post-quantum options such as XMSS, Lamport, WOTS+, and SPHINCS+, while lattice-based schemes such as NTRU, Ring-LWE, Kyber, Dilithium, and Falcon are the most frequently mapped blockchain-oriented alternatives[6][7]. Across the sources, the core trade-off is consistent: stronger quantum resistance usually increases signature size, verification cost, storage, and bandwidth, so practical designs either minimize on-chain overhead or move some verification off the critical path[8][9][10]. Migration-oriented and hybrid designs matter because they let existing networks add quantum resistance without a full rebuild[11][12].

Architectural patterns

  • Hash-based signatures. The surveys identify XMSS, Lamport, SDS, WOTS+, and SPHINCS+ as blockchain-relevant post-quantum schemes, and one proposal uses a hash-based commit-reveal alternative to reduce infrastructure overhead and transaction footprint[13][14].
  • Lattice-based cryptography. The surveys map NTRU, Ring-LWE, GLP, Kyber, Dilithium, and Falcon to blockchain use cases, and a lattice-cryptography preface explicitly describes lattice-based cryptography as the mainstream post-quantum route[15][16]. Applied blockchain papers in the set use NTRU and lattice signatures in prototype architectures[17][18].
  • Migration-oriented validation. An Ethereum-compatible framework retrofits existing chains with post-quantum key generation, post-quantum TLS and X.509, Falcon-512 as a second transaction signature, and three on-chain verification paths: Solidity smart contracts, a modified EVM opcode, and precompiled smart contracts[19].
  • Hybrid consensus and validation. The surveys emphasize that quantum-safe blockchain work must also address consensus, including proof-of-work vulnerability, Byzantine-agreement style protocols, proof-of-stake, BFT-style approaches, and hybrid migration designs[20][21][22].

Performance trade-offs

The benchmarking and prototype studies consistently frame performance as a three-way balance among security, throughput, and operational overhead. In the 2025 benchmarking paper, ML-DSA, Falcon, SPHINCS+, Mayo, and Cross are benchmarked for key generation, signing, and verification, then their effects are simulated for Bitcoin and Ethereum block verification[23]. In the cloud prototype, NTRU signatures and verification are reported as 1024 bytes, with key generation at 2.41 ms, signing at 1.82 ms, and verification at 1.27 ms, while lightweight hash validation stayed effectively constant from 50 to 500 transactions, remained under 5 ms per block, and saw latency rise only from 168 ms to 189 ms as nodes scaled from 50 to 500[24][25][26].

StudyWhat it reportsMain trade-off
Assessing the Impact of Post-Quantum Digital Signature Algorithms on Blockchains[27]Benchmarks key generation, signing, and verification for ML-DSA, Falcon, SPHINCS+, Mayo, and Cross, then simulates effects on Bitcoin and Ethereum block verification[28].Post-quantum security comes with measurable performance and overhead differences across signature families[29].
The Cost of Quantum Resistance: A Hash-Based Commit-Reveal Alternative for Minimizing Blockchain Infrastructure Overhead[30]Analyzes storage, bandwidth, and validation overhead from larger post-quantum signatures, then proposes a hash-based commit-reveal design to keep the transaction footprint low[31].The design goal is to reduce on-chain bloat while preserving quantum resistance[32].
Linkable Ring Signature for Privacy Protection in Blockchain-Enabled IIoT[33]Introduces a lattice-based linkable ring signature with smaller public keys and signatures, plus lower computation overhead and time cost[34].Smaller crypto objects improve efficiency, but the paper is focused on an applied IIoT setting rather than general blockchain consensus[35].

Case studies

Case studyDesign patternLesson from the paper
Quantum-resistance in blockchain networks[36]End-to-end retrofit for existing Ethereum-compatible networks using quantum entropy for key generation, post-quantum TLS and X.509, Falcon-512 for a second transaction signature, and three on-chain verification mechanisms[37][38].The lesson is that practical retrofitting of existing chains is a major design goal, especially when the alternative would require a much larger quantum-safe network stack[39][40].
A scalable post quantum secure blockchain framework with adaptive time consensus in cloud environments[41]NTRU-based post-quantum cryptography combined with adaptive PoET consensus and Lightweight Hash Validation[42].The lesson is that cryptography, consensus, and validation should be designed together if the system is to remain scalable and energy-efficient under heterogeneous cloud loads[43][44].
Research on blockchain smart contract technology based on resistance to quantum computing attacks[45]Lattice-based signatures plus an identity-agent P2P network for cross-chain authentication[46].The lesson is that lattice signatures can be paired with smart-contract-based identity management to support heterogeneous-chain communication[47].
Eliminating single points of trust: a hybrid quantum and post-quantum blockchain with distributed key generation[48]Distributed key generation, a dual-layer signature mechanism combining quantum digital signatures with classical post-quantum lattice cryptography, and delegated proof-of-stake with Borda count[49].The lesson is that hybrid designs can reduce single-point trust and target higher scalability and collusion resistance while avoiding full dependence on one quantum trust anchor[50][51].

Provenance, confidence, and gaps

The evidence set spans a 2021 lattice-cryptography preface, 2024 and 2025 surveys, and 2023 to 2026 prototype or model-based papers[52][53][54][55]. Confidence is high that hash-based and lattice-based primitives are the main quantum-safe options discussed for blockchain, and that migration and hybrid consensus are the dominant architecture responses[56][57][58][59]. The main gap is deployment evidence: the searched materials are dominated by surveys, prototypes, and model-based studies, with limited deployment evidence surfaced in these memories; the Ethereum-compatible retrofit is the closest practical case, but the supplied text does not establish broad production deployment[60][61].
