Examining the Role of Homework Compliance in Acceptance-Enhanced Behavior Therapy for Trichotillomania
No full textBetween-session therapy homework is a key component of cognitive-behavioral therapies, yet its role in trichotillomania treatment remains understudied. The present study examined the associations between homework compliance and treatment outcomes in acceptance and commitment therapy (ACT) enhanced behavior therapy (AEBT) for trichotillomania. Participants included 35 adults with trichotillomania who participated in a 12-week randomized controlled trial of AEBT. Therapists documented patient homework assignment completion and rated homework adherence after each session. Trichotillomania symptom severity was assessed posttreatment and at 6-month follow-up. Higher overall homework completion rate and therapist-rated homework adherence predicted lower trichotillomania symptom severity at posttreatment and follow-up. These findings were consistent for homework compliance during early and late treatment phases and for both ACT and behavior therapy–based homework assignments. A stronger therapeutic relationship strengthened the positive effects of homework compliance on symptom reduction. Higher automatic pulling moderated the association between overall homework completion and better outcomes. Predictors of higher homework compliance included higher therapeutic relationship quality, younger age, and lower anxiety. These findings underscore the importance of between-session homework in trichotillomania treatment and support the inclusion of both ACT and behavior therapy assignments. Interventions to promote homework compliance could enhance the efficacy of AEBT and lead to greater symptom improvements
The Past as Prologue: How Historic Relations with the Federal Government Encouraged Foundations of Resilience and Autonomy for the Metlakatla Indian Community During the COVID-19 Pandemic
Get PDFHistoric relationships with the federal government, converged with the strong cultural heritage, autonomy and self-reliance of the Metlakatla Indian Community (MIC) created foundations for strategic resilience during the COVID-19 pandemic. Sentinel milestone events impacting the MIC during the 19th, 20th, and 21st centuries, initiated by the President of the United States, Congress, and the Federal Courts, are analyzed in the context of their impact and support of evolving tribal-centered development and enaction of protections for the MIC
How Does Fiscal Decentralization Shape Corruption?
Get PDFIn this paper, I offer a comprehensive review of the impact of fiscal decentralization on corruption. Corruption has been a big hindrance to development, it undermines the inflow of foreign direct investment and even affects education. The literature on fiscal decentralization and corruption has conventionally argued that fiscal autonomy for local officials lowers corruption whereas most recent papers have found that fiscal decentralization increases corruption. I identify four possible pathways through which fiscal decentralization affects corruption and address possible reasons for the difference in findings in the literature. Understanding the mechanisms through which fiscal decentralization shapes corruption at the national and local levels may help policy makers design governance structures that enhance accountability and improve public service delivery, reducing corruption’s harmful impacts on investment and development

Seeding Rate, Planting Date, and Herbicides for Dormant Seeded Safflower in Utah
Get PDFDryland crop production in the Intermountain West is largely limited by the amount of precipitation received. Increasing dryland safflower (Carthamus tinctorius L.) production yields in a semi-arid climate is possible with a dormant planting but is not well understood. A two-year (2020-22) project was designed to gain an understanding of the effects of variety, seeding rate, and planting date, on dormant seeded safflower. Chemical weed control options for safflower were also evaluated. One study, conducted at three Utah State University research farms near Blue Creek, Clarkston, and Kaysville, UT, evaluated four varieties, S-208, S-333, 7325 and Hybrid-446, seeded at five rates and planted in the fall and spring. Safflower was sown at 6.7 (spring only), 13.5, 20.2, 26.9, 33.6, and 40.4 (fall only) kg ha-1. Fall seeded safflower had lower plant densities but an increase in pods per plant when comparing identical seeding rates of both planting dates. At Kaysville, all four varieties displayed an increase in seed yield with fall planting during both years of the study. Seed quality differed in oil content among varieties with Hybrid-446 being lower (32-34%). Planting at lower seeding rates tended to result in higher seed oil content. Greatest yields for fall planting were achieved with a seeding rate of 20.2 kg ha-1. Another experiment conducted at Blue Creek and Clarkston, UT, evaluated chemical weed control options. Treatments comprised of herbicide(s) used, timing of application and rate applied. In general, fall applications gave the same, and at times better, control of Russian thistle (Salsola tragus L.), prickly lettuce (lactuca serriola L.), kochia (Bassia scoparia L.) and volunteer wheat (Triticum aestivum L.), compared to spring applications. Overall, liquid ethalfluralin or the highest rates of sulfentrazone (280 to 560 g ha-1) applied in the fall, demonstrated reasonable control of weeds. Greatest yields (515 kg ha-1) came from plots treated with highest rates of sulfentrazone following planting in the fall. Results suggest an optimal seeding rate of 20.2 kg ha-1, with ethalfluralin or sulfentrazone effectively managing weeds. Compared to spring, fall planting will have reduced stand establishment, but increased pods plant-1, which may result in increased yield
Drought Resilience and Legacy Effects in Two Forest Tree Species on Loess Plateau of China: Growth and Water-Use Efficiency Under Different Drought Conditions
Get PDFAs droughts become more frequent and severer, understanding tree resilience and its role in mediating drought legacy effects (LEs) is critical for predicting forest ecosystem responses to future droughts and informing forest management. Both Pinus tabuliformis and Populus davidiana are widely distributed in the Loess Plateau region of western China and play important roles in provision of ecosystem services. In this study we quantified the LEs and resilience, including resistance (Rt) and recovery (Rc), of radial growth (BAI, basal area increment) and intrinsic water use efficiency (iWUE) of the two species, determined the external and internal factors influencing Rt and Rc, and disentangled the respective contribution of Rt and Rc to LEs in the these two tree species. We found either negative or positive legacy effects in BAI (LEBAI) and iWUE (LEiWUE) in both species, mostly lasting for 1–3 years. Species differences were only detected in LEiWUE during the severer drought event. But species variation in resilience did not differ. P. tabuliformis exhibited lower Rt but higher Rc than P. davidiana. Tree diameter and drought intensity were negatively correlated with Rt and Rc; whereas tree age and growth variability positively influenced both resilience components. In P. tabulaeformis, the influence of Rt was stronger on LE than on Rc during the milder droughts, whereas during the severer droughts LE was affected by Rc. The reversed patterns of the effects were exhibited by P. davidiana. Our findings help advance current understanding on the factors driving resilience and how trees use different resilience strategies under different drought conditions to alleviate negative LEs
Assessment of \u3ci\u3ePopulus tremuloides\u3c/i\u3e (Michx) Mechanical Characteristics for Glulam Production
No full textThis project aimed to document the mechanical properties, the bonding, and joint performance of trembling aspen to improve its use in Engineered wood products. It also aimed to study the bending characteristic and investigate the failure behavior of full-size beams made of trembling aspen. Non-destructive and destructive tests were conducted on lamellae of trembling aspen (Populus tremuloides Michx) following the ASTM D198. Full-size beams were manufactured following the manufacturing principles outlined in the CSA-0122, the standard for glulam production in Canada, to evaluate the performance of finger jointing, block-shear and delamination, and to establish the glulam\u27s bending strength. Mechanical tests on trembling aspen assessed a 5th percentile value of 13.8 MPa in tension, and 40.9 MPa in bending with a mean modulus of elasticity of 10,343 MPa. The relationship between dynamic and static modulus of elasticity was analyzed and showed a strong correlation, with low relative error, and its feasibility for machine stress rating. The test conducted on the finger joint shows a characteristic value of bending strength of 31.8 MPa. The block-shear and delamination align with the requirement from the standards CSA-0122. The investigation of the bending performance on the glulam made of trembling aspen achieved a mean strength resistance of 30.3 MPa, once modified to be compared with the values from the standard, is lower than the MOR value required from the standard. In addition to the mean modulus of elasticity determined of 9013 MPa, it is also lower than the value from the standard

300-900 MHz Midband Array Design for the Lunar Farside Technosignatures and Transients Telescope
No full textThe Lunar Farside Technosignature & Transients Telescope (LFT3), planned as an ultra-high frequency (UHF) phased array near the lunar antipode, is introduced as a pioneering mission capitalizing on recent advancements in analog beamforming. LFT3\u27s midband array specifically leverages a described analog beamformer to achieve critical baseline measurements, enabling observations of astrophysical phenomena free from terrestrial interference. The authors describe the development of a wideband, low-power analog beamformer suitable for lunar-based radio astronomy, evaluating the primary architectures: a combiner tree, Rotman lens, Butler matrix, Nolen matrix, and Blass matrix. Each approach is analyzed in terms of performance, complexity, reliability, and suitability for implementation on a space-secured lunar lander. Measurements and comparative analysis highlight distinct trade-offs, revealing that a Blass matrix incorporating true time delays offers the highest reliability, lowest complexity, and minimal component count, making it optimal for low-power lunar operations
Development and Implementation of Compact LET Joints for Origami-Based Deployable Arrays
No full textLamina emergent torsion (LET) arrays are not area efficient and exhibit significant parasitic motion. This makes them unsuitable for use in highly compact applications such as origami-based deployable arrays. This work presents a compact variation of the conventional LET array which resolves these issues. A method for fabricating these compact LET arrays, or C-LETs, from carbon fiber-reinforced polymer is given. Deflection and stress models for C-LETs are shown, and initial steps taken toward validating these models. A prototype origami-based deployable reflectarray incorporating C-LETs demonstrates that they provide the desired motion while maximizing the usable area of the array
