Acquisition Strategy For Innovation Under Competence-Destroying Change: Empirical Study—Pharmaceutical Company's Biotechnology Company Acquisition, Joo Tae Sung Jun 2025

Acquisition Strategy For Innovation Under Competence-Destroying Change: Empirical Study—Pharmaceutical Company's Biotechnology Company Acquisition, Joo Tae Sung

Dissertations and Theses Collection (Open Access)

In response to declining R&D productivity and successive patent cliffs, pharmaceutical companies are increasingly acquiring biotechnology firms to sustain innovation. These acquisitions often occur under conditions of competence-destroying change, where the acquirer's chemistry-based knowledge base does not overlap with the biotechnology expertise of the target, challenging traditional theories that emphasize absorptive capacity and knowledge similarity.
This study introduces therapeutic knowledge, defined as the acquirer’s expertise in specific disease areas, as a distinct and critical dimension that interacts with both chemistry-based and biotechnology-based knowledge. Using a dataset of 212 observations across therapeutic areas from 80 acquisitions, the analysis uncovers an inverted …


Woofs And Warbles: The Influence Of Urban Dog Walking On Birdsong, Grace Phillips Jun 2025

Associations Between Vitamin D Deficiency And Sociodemographic Factors, Lifestyle Behaviors, And Metabolic Conditions: A Cross-Sectional Study From The Hnnhs In Greece, Asmae Mohamad Sadek Jun 2025

Associations Between Vitamin D Deficiency And Sociodemographic Factors, Lifestyle Behaviors, And Metabolic Conditions: A Cross-Sectional Study From The Hnnhs In Greece, Asmae Mohamad Sadek

Theses

Vitamin D deficiency (VDD) is a widespread global health concern associated with various sociodemographic, lifestyle, dietary, and metabolic factors. While previous studies examined VDD in Greece, few provided a comprehensive analysis across multiple determinants using representative national data. This study aimed to assess the prevalence and predictors of VDD among Greek adults and to examine its associations with sociodemographic, dietary, behavioral, and metabolic variables using data from the Hellenic National Nutrition and Health Survey (HNNHS). A cross-sectional analysis was conducted among 978 adults (≥19 years) from the HNNHS. Serum 25-hydroxyvitamin D [25(OH)D] concentrations < 20 ng/mL were defined as deficient and ≥20 ng/mL as normal. The median age of participants was 40.2 years, and 62.0% were female. The overall prevalence of VDD was 46.0%, with the highest rate observed among adults aged ≥60 years (62.2%). VDD was significantly associated with older age (p < 0.001), retirement status (62.9% among retired; p < 0.001), low and sedentary physical activity (32.7% and 32.6% vs. 50.8% among highly active; p < 0.001), higher HDL (median 52.0 vs. 49.0 mg/dL among VDD vs Normal; p = 0.001), elevated serum calcium (median 9.4 vs. 9.2 mg/dL among VDD vs Normal; p = 0.020), and lower insulin levels (median 7.5 vs. 8.0 μIU/mL among VDD vs Normal; p = 0.044). Dietary intake (total energy and macronutrients) and body composition were not significantly associated with VDD. In the multivariate model, significant independent predictors of VDD included being retired (AOR = 2.383; 95% CI: 1.596–3.558; p < 0.001), having higher serum calcium levels (AOR = 1.563; 95% CI: 1.078–2.266; p = 0.019), and higher HDL levels (AOR = 1.016; 95% CI: 1.005–1.027; p = 0.001). Physical activity level was also a key determinant; participants classified as sedentary or low active had significantly higher odds of deficiency compared to highly active individuals (AOR = 0.468; 95% CI: 0.319–0.690; p < 0.001). This counterintuitive result may be influenced by factors such as increased indoor physical activity, and warrants further investigation. Dietary intake and body composition were not significantly associated with VDD. The findings underscore the importance of incorporating sociodemographic and lifestyle factors into prevention strategies. Interventions should particularly focus on older adults, retired individuals, even if they have higher HDL and calcium levels, and are physically active.

Research outputs 2022 to 2026

Objectives: Previous studies have confirmed that biological age (BA) acceleration is associated with single cardio-renal–metabolic diseases (CRMDs), typically including type 2 diabetes mellitus, cardiovascular disease, and chronic kidney disease. However, its association with progression to cardio-renal–metabolic multimorbidity (CRMM, coexistence of ≥2 CRMDs) and subsequent mortality remains unexplored. Methods: Using the multi-state model, we analyzed 278,927 UK Biobank participants free of CRMDs at baseline to investigate the association between BA acceleration—measured by phenotypic age (PhenoAge) and Klemera–Doubal method age (KDMAge)—and CRMM progression trajectory, from health to the first CRMD and then to CRMM and death. BA acceleration was the residual from …

Does Pollination By Non-Flying Mammals Contribute Substantially To Fruit Set Of Banksia (Proteaceae)? A Test In Four Species With Contrasting Floral Traits, Stanislaw K. Wawrzyczek, Robert A. Davis, Siegfried L. Krauss, Susan E. Hoebee, Ryan D. Phillips

Research outputs 2022 to 2026

Pollination by non-flying mammals (NFMs) is thought to be associated with cryptic, dull coloured, strongly scented flowers. In Western Australia, various Banksia species exhibit these traits, suggesting adaptation to primary pollination by NFMs, particularly the marsupial honey possum (Tarsipes rostratus). Here, we compare floral visitation rates and assess contribution to fruit set of NFMs and other pollinators in four species of Banksia with contrasting floral traits. Camera trap-based surveys revealed that honeyeater birds visited all species equally and were more frequent visitors than NFMs to the brightly coloured, unscented flowers of B. sessilis and B. splendida. By contrast, NFMs were …

Research outputs 2022 to 2026

Circulating tumour DNA (ctDNA) is a promising biomarker for personalised oncology. However, its clinical utility is limited by detection sensitivity, particularly in early-stage disease. T-Oligo Primed Polymerase Chain Reaction (TOP-PCR) is a commercial amplification approach utilising an efficient “half-adapter” ligation design and a single-primer-based PCR strategy. This study evaluated the clinical value and application of cell-free DNA (cfDNA) pre-amplification. cfDNA amplification with TOP-PCR preserved DNA size profiles and resulted in a 22 bp size increase due to the half-adaptor ligation. Gene target amplification rates varied, showing lower efficiency for the GC-rich TERT promoter amplicon and higher efficiency for the BRAF …

Spring Field Report, March–May 2025, W. Ross Silcock Jun 2025

Spring Field Report, March–May 2025, W. Ross Silcock

Nebraska Bird Review

Perhaps the most important takeaway this spring is the continuing phenomenon of large numbers of species with early spring arrival dates. Although about half as many as 2024, there were 64 examples of either tied or new early arrival dates, most obviously of insectivores such as swifts, flycatchers, vireos, swallows, pipits, longspurs, and 10 warbler species. Among these, record or near-record early were Whip-poor-will, Black-necked Stilt, Marbled Godwit, Black Tern, Olive-sided Flycatcher, Purple Martin, Rock Wren, Gray Catbird in central, Spotted Towhee in north and west, and Hooded Warbler.

Following along logically perhaps with early arrival dates were a number …

School of Medicine Publications

Recent high-throughput sequencing technologies have discovered various polymerase II transcribed transcripts. The majority of them are non-protein-coding, understudied, and poorly conserved. Noncoding transcripts are categorized based on their location in the genome and the direction in which they are transcribed; these categories classify a noncoding transcript as either antisense, intergenic, or divergent. The RNAs belonging to divergent classes consist of two transcripts, transcribed in sense and antisense direction, generated from the same promoter or locus. Multiple environmental and genetic cues can determine the regulation of these transcripts. One of the well-known signaling molecules, estrogen, has been shown to play a …

When Trees Disappear: Understory Successional Implications Of Sudden Oak Death And High-Severity Wildfire In Big Sur, California, Sam J. Balthazard Jun 2025

When Trees Disappear: Understory Successional Implications Of Sudden Oak Death And High-Severity Wildfire In Big Sur, California, Sam J. Balthazard

Master's Theses

The rapidly emerging disease sudden oak death, caused by the non-native pathogen Phytophthora ramorum, is transforming coastal California forests by driving extensive mortality of tanoak (Notholithocarpus densiflorus) and increasing fire severity. As a novel disturbance, sudden oak death and its interaction with wildfire may catalyze unexpected shifts in successional trajectories and reconfigure forest understory communities. Furthermore, how tanoak influences the forest understory and how its decline might reshape understory dynamics remain poorly understood. We hypothesize that disease alone and the compounding disturbances of disease and wildfire alter successional dynamics, and that the potential functional extinction of N. …
