The Non-Waivability Principle: Possible Derogations From Collective Bargaining And Re-Assessment Of Individual Bargaining In Assisted Procedures, Elena Gramano, Silvio Sonnati

Comparative Labor Law & Policy Journal

This article examines the evolving landscape of Italian labour law, with a focus on the principle of non-waivability and its gradual adaptation to demands for flexibility and competitiveness. Traditionally, the Italian labour law framework has been characterised by a strong non-waivability regime, which protects employees from negotiating away their rights due to inherent power imbalances vis-à-vis employers. However, recent regulatory developments have facilitated a shift towards both collective and individual agreements that allow deviations from statutory provisions, including to the detriment of employees. The article analyses the implications of this trend, exploring key regulatory models that enhance the role of …

Waiver Of Statutory Employment Rights In The United Kingdom, Hugh Collins

Comparative Labor Law & Policy Journal

The common law endorses the principle of freedom of contract, but, with few exceptions, Parliament has explicitly prevented straightforward waivers of statutory employment rights. Nevertheless, for the sake of promoting settlements of claims by employees, it is surprisingly easy for individual employees to enter into agreements to compromise claims for breach of those rights without appropriate safeguards such as independent advice and freedom from pressure. Moreover, employers’ lawyers have demonstrated considerable ingenuity in finding ways to avoid the application of employment rights either by manipulations of employment status or by seeking contractual agreements on the facts of the case that …

Relaxation Of Mandatory Rules Through Collective And Individual Agreements In Japanese Labour Law, Ryuichi Yamakawa

Comparative Labor Law & Policy Journal

This article analyses the legal situation in Japan regarding the relaxation of or deviation from mandatory regulations in labour law through collective and individual agreements. Although many statutory labour laws in Japan have a mandatory effect over individual employment contracts, several statutory provisions provide that such mandatory regulations can be relaxed through collective agreements under certain circumstances, as is the case in other industrialised countries. However, Japan’s situation is unique insofar as the relaxation is permissible through collective agreements concluded by non-union (individual) representatives of a majority of employees in the absence of union representatives who have been elected by …

Derogability By Collective Agreements In Germany And The Presumption, Eva Kocher

Comparative Labor Law & Policy Journal

The promotion of derogability clauses, which allow collective agreements to deviate from statutory protection to the detriment of employees, has been an issue in the political debate on German labour law for some 20 years. While such derogability clauses can effectively allow for flexibility at the company or sectoral level, there are differing views on their suitability for promoting collective bargaining. This article highlights the paradox of such derogability clauses: They are legitimised by the presumption of fairness that underpins collective autonomy; at the same time, they create incentives for employers that challenge the very presumption of fairness. All in …

Derogability From Swedish Statutory Labour Law, Birgitta Nyström

Comparative Labor Law & Policy Journal

The possibility for the social partners to derogate from statutory legislation in the area of labour and employment law is an important characteristic of the so-called “Swedish model” for industrial relations and labour market regulation. With a system built on collective bargaining and collective agreements, and where legislation in the labour law area was rather scarce until the 1970s, freedom for the social partners is a core element. The possibility to derogate from certain parts of statutory labour law by collective agreements also gives room to adapt rules for different kinds of businesses and trades. Sweden is a member of …

University Placed-Based Community Engagement And Adult Learners: A Field Report In Mutual Flourishing, Elisabeth Stevens, Kate Witvliet, Abbie Lipsker, Craig Mattson

University Faculty Publications and Creative Works

Although higher education increasingly focuses on both community engagement and adult learners, community-engaged research rarely considers them together. This article bridges the gap in the literature between undergraduate adult learners and community engagement. Providing one example of a partnership that considers adult learners as necessary partners for community engagement, Calvin University’s 49507 Initiative is a place-based community educational project in southeast Grand Rapids, Michigan, focusing on the goals and needs of adult learners in the 49507 zip code and adjacent neighborhoods. Through 12 focus groups in the community, adult residents discussed their interests in higher education, identified barriers to higher …

S6k1 Modulates Stat3 Activation To Promote Resistance To Radiotherapy In Lung Cancer, Ali Calderon-Aparicio, Noelle Francois, Tyler Grenda, Shan Xu, Olugbenga Okusanya, Jun He, Nicole L Simone

Department of Radiation Oncology Faculty Papers

Radiotherapy is a mainstay in the management of locally advanced lung cancer; however, intrinsic and acquired radioresistance contribute to poor prognosis. S6K1, a serine/threonine kinase, regulates cell growth, protein synthesis, and survival, and is increased in tumors, which is linked to enhanced survival under therapeutic stress, including radiation. The mechanisms, however, are not fully understood. This study investigates the role of S6K1 in lung cancer radioresistance and the mechanisms involved. Intrinsic radioresistance in lung cancer cells was associated with increased S6K1 activation. Pharmacologic inhibition or genetic deletion of S6K1 enhanced radiosensitivity both in vitro and in vivo, highlighting the therapeutic …

Empowering Neurodiverse Talent In Cybersecurity Through Fair And Inclusive Ai Education, Sheikh Rabiul Islam, Yansi Keim, Mohiuddin Ahmed, Maanak Gupta, Ingrid Russell, Mahmoud Abdelsalam

Research outputs 2022 to 2026

Cybersecurity demands creativity, persistence, and sharp pattern recognition—strengths frequently reported among neurodivergent people (e.g., autism, ADHD, dyslexia). Yet AI-driven hiring pipelines can systematically disadvantage neurodivergent applicants by misreading communication styles or valuing narrow proxies of “fit.” Demand for cybersecurity talent is growing, and experts note that neurodiverse individuals are both underrepresented and highly valuable to security teams. However, progress remains uneven without targeted educational interventions [1]. We present a curricular module that simultaneously (a) centers neurodiversity as a strength in the cybersecurity workforce and (b) trains students to audit and redesign AI hiring systems using open-source fairness and explainability toolkits …

Effect Of Degree Of Saturation On The Liquefaction Resistance Of Non-Plastic And Low-Plastic Soils, Kayla Rae Sorenson

Dissertations and Theses

Liquefaction and cyclic softening of fine-grained soils pose a significant hazard during earthquakes, yet the cyclic behavior of transitional soils such as silts remains poorly understood. Existing empirical liquefaction evaluation frameworks and ground improvement techniques are largely developed for sands and are not directly applicable to silts, particularly beneath existing infrastructure where conventional mitigation methods are often impractical or cost prohibitive. This knowledge gap is critical in regions such as the Pacific Northwest, where young, loosely deposited silts are prevalent and susceptible to seismic loading.

Microbially induced desaturation (MID) has emerged in recent years as a promising, minimally invasive ground …

Evaluating The Implementation Of Oregon's Dsm-5-Informed Autism Eligibility Revisions: Interest-Holder Perspectives And Policy Implications, Bradley Josef Hendershott

Dissertations and Theses

Under the Individuals with Disabilities Education Act (IDEA), states establish their own autism spectrum disorder (ASD) eligibility criteria, resulting in substantial interstate variation and frequent misalignment with medical diagnostic standards. In 2019, Oregon revised its ASD eligibility criteria by directly incorporating DSM-5 diagnostic criteria, reflecting proponents' theory of action that this alignment would improve conceptual clarity, identification accuracy, and coherence across educational and medical systems. While an early implementation study documented generally positive early effects reported by evaluators, no research has systematically examined whether the DSM-5 alignment achieved its anticipated effects, how the revised criteria function after multiple years of …

Remnant Cholesterol And Atherosclerotic Cardiovascular Disease Risk In Populations With Different Low-Density Lipoprotein Cholesterol Elevations: A Prospective Cohort Study, Hong Zheng, Guanlin Chen, Zhenyu Huo, Yulong Lan, Yuxian Wang, Peng Fu, Weiqiang Wu, Haixiang Zheng, Kuangyi Wu, Zegui Huang, Dan Wu, Shouling Wu, Youren Chen

Research outputs 2022 to 2026

Background: Low-density lipoprotein cholesterol (LDL-C) and remnant cholesterol (RC) are risk factors for atherosclerotic cardiovascular disease (ASCVD). However, the extent to which differences in RC levels affect ASCVD risk in populations with varying degrees of LDL-C elevation remains unclear. This study aimed to investigate whether RC can provide additional risk stratification value across different sexes, ages, and elevated LDL-C statuses. Methods: This study included 12 743 elevated LDL-C participants (LDL-C ≥3.4 mmol/L) and 50 073 age- and sex-matched non-elevated LDL-C controls from the Kailuan Study. Elevated LDL-C participants were categorized by RC levels into <0.5, 0.5 to <1.0, and ≥1.0 mmol/L subgroups. Kaplan-Meier curves and Cox proportional hazards models were used to assess the relationship between RC levels and ASCVD risk across different sexes, ages, and high LDL-C statuses. Results: During a median follow-up of 12.8 years, 1686 elevated LDL-C participants (13.2%) and 5252 non-elevated LDL-C participants (10.5%) developed ASCVD. In the borderline-high LDL-C group (3.4 ≤ LDL-C < 4.1 mmol/L), those with the lowest RC levels showed no significant risk difference compared with controls (hazard ratio [HR], 1.03 [95% CI, 0.93-1.13]), and this pattern remained consistent across different sexes and ages. In contrast, in the high LDL-C group (LDL-C ≥4.1 mmol/L), even when RC was at the lowest level, ASCVD risk remained significantly higher than that of controls (HR, 1.20 [95% CI, 1.02-1.41]). CONCLUSIONS: In the borderline-high LDL-C population, those with the lowest RC levels showed no significant risk difference compared with controls, and this pattern remained consistent across different sexes and age subgroups. In the high LDL-C population, even when RC was at the lowest level, ASCVD risk remained significantly higher than that of controls.

Validating Uas-Based Ndvi Data With Satellite Landsat Imagery For Bald Eagle Habitat Prediction In The Del Rio Springs Ecosystem, Noah Morales, Ronny Schroeder, Elise Anderson

Student Works

Vegetation health is commonly assessed using the Normalized Difference Vegetation Index (NDVI), which can be derived from multispectral sensors operating at different spatial resolutions. Validating NDVI products across sensor platforms is essential to determine their reliability for environmental monitoring and habitat assessment. This research compares NDVI derived from moderate-resolution satellite imagery and high-resolution unmanned aircraft system (UAS) imagery collected over the same study area. Landsat imagery, provided through the joint USGS–NASA mission, was used to represent satellite-based vegetation patterns, while high-resolution multispectral data were acquired using a MicaSense sensor mounted on a UAS to capture fine-scale vegetation detail.

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest malignancies, with a 5-year survival rate of just 13%. While the development and early clinical use of small molecules targeting oncogenic KRAS mutations, key drivers of PDAC, have shown promise, resistance to these targeted therapies remains a significant challenge. We recently identified Syndecan-1 (SDC1), a highly expressed heparan sulfate proteoglycan, as a critical KRAS effector protein that promotes nutrient salvage and tumor growth. Here, we report the development of a human-specific monoclonal antibody (anti-SDC1 mAb) that inhibits PDAC cell proliferation in vitro and suppresses PDAC tumor growth in vivo. Mechanistically, …

Triple-negative breast cancer (TNBC) exhibits heterogeneous treatment responses, yet molecular subtypes based on predefined biological pathways show limited prognostic value. We introduce tumor-specific total mRNA expression (TmS), a pathway-agnostic deconvolution metric derived from matched RNA/DNA sequencing, as a robust stratification tool. Analyzing 575 TNBC patients across Western and East Asian populations, TmS outperforms established subtypes in predicting chemotherapy outcomes, stratifying patients into high TmS with favorable prognosis and low TmS with poor prognosis. Stromal enrichment with immune exclusion emerges as a universal feature of chemotherapy-resistant low-TmS tumors across all cohorts. Population-specific features distinguish Asian cohorts: high-TmS tumors exhibit cell cycle-driven …

Regalado V. Hughes Avenue Corp. And The Department Of Housing Preservation And Development Of The City Of New York

All Decisions

In this HP proceeding, the tenant moved for civil contempt and civil penalties against the landlord for failing to comply with a consent order to correct HPD violations, including those for mold and lead-based paint. The court granted the tenant's motion, finding the landlord in civil contempt for non-compliance with the order. The landlord's arguments, including a vague superintendent's affirmation and an unauthenticated D.H.P.D. repair bill, were insufficient to rebut the presumption that violations persisted. The court imposed a $350 per day fine, payable to the tenant, until outstanding "C" and "B" violations are corrected, and referred the calculation of …

17 Pennsylvania Avenue Hdfc V. Ventura

All Decisions

In this holdover proceeding concerning an HDFC, the Civil Court of the City of New York granted the tenant's motion for summary judgment, dismissing the case. The landlord sought to evict the long-term tenant, alleging good cause based on consistent failure to pay rent. However, after applying DRIE credits, the landlord's records only showed three months of unpaid rent totaling $1,500 from 2020. The court, citing precedent and emphasizing the affordable housing purpose of HDFCs, found that this minor, unpursued debt from several years prior did not constitute good cause for eviction. The tenant's counterclaim for harassment was severed.

PURPOSE: Low-grade serous ovarian carcinoma (LGSOC) is a distinct form of ovarian cancer characterized by younger patient age and relative chemoresistance. The GOG281/LOGS trial (NCT02101788) investigated the efficacy of the MEK inhibitor trametinib compared with physician's choice standard-of-care (SOC) in patients with LGSOC with persistent/recurrent disease. The study demonstrated significantly improved progression-free survival (PFS) in the trametinib-treated arm.

EXPERIMENTAL DESIGN: Two hundred and sixty patients with recurrent/persistent LGSOC were enrolled and randomly assigned in GOG281. We performed molecular analysis of 170 patients with available tumor specimens, comprising whole-exome sequencing and phospho-ERK (pERK) IHC, to identify biomarkers of clinical benefit from …

Optimization of prophylactic vaccine regimens to elicit strong, long-lasting immunity is an urgent need highlighted by the COVID-19 pandemic. Stronger vaccine immunogenicity is frequently reported in individuals living in high-income countries compared to individuals living in low- and middle-income countries. While numerous host genetic and immune factors may influence vaccine responses, geographic restrictions to vaccine effectiveness may also be influenced by the intestinal microbiota, which modulates host immune systems. However, the potential role of the gut microbiota on responses to HIV-1 vaccines has not yet been explored. We analyzed the bacteriome by targeted 16S sequencing and the virome by virus-like …

Animals must balance behavioral goals with the energetic costs of movement. How such trade-offs are implemented algorithmically during natural behavior, and how they adapt to changing energetic constraints, remains poorly understood. Here we show that larval zebrafish adjust their motor strategies during prey hunting to minimize energy expenditure. Using high-speed video tracking and 3D computational fluid dynamics simulations, we quantified the energy costs (in Joules) of different movement types across three developmental stages. While the structure of discrete movement types ("bouts") remained stable with age, their selection probabilities changed depending on their energetic cost, such that more expensive bouts were …

Accurate Interpretation Of Within-Host Dissemination Using Barcoded Bacteria, Rachel T Giorgio, My T Le, Ting Zhang, Caitlyn L Holmes, Karthik Hullahalli

2020-Current year OA Pubs

Bacterial dissemination across tissues is a critically important process influencing infection outcomes. Monitoring within-host dissemination is challenging because conventional measures of bulk bacterial burden cannot distinguish between lineages that are shared between tissues and those that replicate locally. This limitation can be overcome using barcoded bacteria, where deep sequencing of the barcode locus and comparisons of barcodes between tissues define which lineages spread within the host. Numerous studies have used barcoded bacteria to generate high-resolution maps of dissemination. However, since multiple cells in the infectious inoculum can contain identical barcodes, inferences about dissemination can be confounded when distinct lineages from …
