Developing A Strategy For Synergy Between Home And Church To Increase Youth Engagement And Faith Formation At Barriere Adventist Church, Timoteus Nagy
Developing A Strategy For Synergy Between Home And Church To Increase Youth Engagement And Faith Formation At Barriere Adventist Church, Timoteus Nagy
Doctor of Ministry Projects
Problem
There was no intentional synergistic relationship between the home and the church at the Barriere Adventist Church. As a result, church leaders often expressed discouragement when they saw teens become disengaged with church and spirituality. They suggested that the root problem of this symptom was the lack of cooperation between the two faith-forming institutions in keeping young people engaged and growing in their faith. As a pastor, I saw this deficiency and our urgent need for change.
Method
A six-month action research strategy was designed and delivered at the Barriere Adventist Church. Twenty members from every generational cohort were …
Inactive Metallopeptidase Homologs: The Secret Lives Of Pseudopeptidases, Peter Lyons
Inactive Metallopeptidase Homologs: The Secret Lives Of Pseudopeptidases, Peter Lyons
Faculty Publications
Inactive enzyme homologs, or pseudoenzymes, are proteins, found within most enzyme families, that are incapable of performing catalysis. Rather than catalysis, they are involved in protein-protein interactions, sometimes regulating the activity of their active enzyme cousins, or scaffolding protein complexes. Pseudoenzymes found within metallopeptidase families likewise perform these functions. Pseudoenzymes within the M14 carboxypeptidase family interact with collagens within the extracellular space, while pseudopeptidase members of the M12 "a disintegrin and metalloprotease" (ADAM) family either discard their pseudopeptidase domains as unnecessary for their roles in sperm maturation or utilize surface loops to enable assembly of key complexes at neuronal synapses. …

School of Biological and Marine Sciences
In addition to well-known effects on species ecophysiology, phenology, and distributions, climate change is widely predicted to impact essential ecosystem services such as decomposition and nutrient cycling. While temperature and soil moisture are thought to influence litter decomposition, elucidating consistent soil process responses to observed or predicted shifts in climate have proven difficult to evidence. Here we investigated how aspect (i.e., north-south orientation), a natural model for variation in soil temperature, influenced soil physico-chemical conditions and decomposition of two standardised litter types (Green tea and Rooibos teabags) in Pole-facing (PF) and Equator-facing (EF) roadside verges spanning a 3000 km and …
The North–South Divide? Macroalgal Functional Trait Diversity And Redundancy Varies With Intertidal Aspect, Axelle Amstutz, Louise B. Firth, Andy Foggo, John I. Spicer, Mick E. Hanley
The North–South Divide? Macroalgal Functional Trait Diversity And Redundancy Varies With Intertidal Aspect, Axelle Amstutz, Louise B. Firth, Andy Foggo, John I. Spicer, Mick E. Hanley
School of Biological and Marine Sciences
Background and Aims Marine macroalgae (‘seaweeds’) are critical to coastal ecosystem structure and function, but also vulnerable to the many environmental changes associated with anthropogenic climate change (ACC). The local habitat conditions underpinning observed and predicted ACC-driven changes in intertidal macroalgal communities are complex and probably site-specific and operate in addition to more commonly reported regional factors such as sea surface temperatures. Methods We examined how the composition and functional trait expression of macroalgal communities in SW England varied with aspect (i.e. north–south orientation) at four sites with opposing Equator- (EF) and Pole-facing (PF) surfaces. Previous work at these sites …

Shift In Algal Blooms From Micro‐ To Macroalgae Around China With Increasing Eutrophication And Climate Change, Yuan Feng, Yonglong Xiong, Jm Hall‐Spencer, Kailin Liu, John Beardall, K Gao, Jingke Ge, Juntian Xu, G Gao
School of Biological and Marine Sciences
Blooms of microalgal red tides and macroalgae (e.g., green and golden tides caused by Ulva and Sargassum) have caused widespread problems around China in recent years, but there is uncertainty around what triggers these blooms and how they interact. Here, we use 30 years of monitoring data to help answer these questions, focusing on the four main species of microalgae Prorocentrum donghaiense, Karenia mikimotoi, Noctiluca scintillans, and Skeletonema costatum) associated with red tides in the region. The frequency of red tides increased from 1991 to 2003 and then decreased until 2020, with S. costatum red tides exhibiting the highest rate …
Perioperative Oxygenation—What's The Stress?, Joseph Larvin, Mark Edwards, Daniel S. Martin, Martin Feelisch, Michael P.W. Grocott, Andrew F. Cumpstey
Perioperative Oxygenation—What's The Stress?, Joseph Larvin, Mark Edwards, Daniel S. Martin, Martin Feelisch, Michael P.W. Grocott, Andrew F. Cumpstey
Peninsula Medical School
Oxygen is the most used drug in anaesthesia. Despite such widespread use, optimal perioperative oxygen administration remains highly controversial because of concerns about the competing harms of both hyperoxia and hypoxia. Notwithstanding a Cochrane review concluding that routinely administering a fractional inspired oxygen concentration (FiO2) >0.6 intraoperatively might increase postoperative morbidity and mortality, the World Health Organization (WHO) currently recommends all anaesthetised patients receive 0.8 FiO2 during and immediately after surgery to reduce surgical site infections. Results from the largest trial available at the time of these two reviews (suggesting long-term survival may be worse with high …
Emigration Of Post-Spawned Twaite Shad Alosa Fallax, An Anadromous And Iteroparous Fish, In A Highly Fragmented River, Mark I.A. Yeldham, J. Robert Britton, Charles Crundwell, Peter Davies, Jamie R. Dodd, Andrew D. Nunn, Randolph Velterop, Jonathan D. Bolland
Emigration Of Post-Spawned Twaite Shad Alosa Fallax, An Anadromous And Iteroparous Fish, In A Highly Fragmented River, Mark I.A. Yeldham, J. Robert Britton, Charles Crundwell, Peter Davies, Jamie R. Dodd, Andrew D. Nunn, Randolph Velterop, Jonathan D. Bolland
School of Biological and Marine Sciences
Anthropogenic barriers are widely known to negatively impact the spawning migrations of anadromous fishes, by delaying or preventing passage upstream. Although the impacts of barriers on emigrating post-spawned adults are less well studied, they could potentially impact the fitness and subsequent return rates of iteroparous species. In this study, passive acoustic telemetry was used to track the emigrations of 53 twaite shad Alosa fallax in the River Severn basin in their first spawning migration a year after being tagged, giving insights into their emigration movements and the impacts of anthropogenic weirs on these movements. A. fallax began their emigrations after …
Inconsistent Bioreceptivity Of Three Mortar Mixes In Subtidal Sites, Jessica R. Bone, Alice E. Hall, Rick Stafford, Roger J.H. Herbert
Inconsistent Bioreceptivity Of Three Mortar Mixes In Subtidal Sites, Jessica R. Bone, Alice E. Hall, Rick Stafford, Roger J.H. Herbert
School of Biological and Marine Sciences
Concrete is extensively used in coastal engineering and development which, in addition to its high carbon footprint, threatens intertidal habitats and ecosystems. Eco-engineering addresses this by designing habitat features into coastal infrastructure. The chemical bioreceptivity of cement has been shown to vary, but ordinary Portland cement is generally considered to be the least bioreceptive. In this study, we compare two low carbon mortars (a natural, single source cement (VP), and an ordinary Portland cement/ ground granulated blast furnace slag blend (GGBS)) with an ordinary Portland cement-based control mix (OPC). The three mortars were made into smooth blocks which were secured …
Transgressive Gene Expression And Expression Plasticity Under Thermal Stress In A Stable Hybrid Zone, Lindsey C. Schwartz, Vanessa L. González, Ellen E. Strong, Manuela Truebano, Thomas J. Hilbish
Transgressive Gene Expression And Expression Plasticity Under Thermal Stress In A Stable Hybrid Zone, Lindsey C. Schwartz, Vanessa L. González, Ellen E. Strong, Manuela Truebano, Thomas J. Hilbish
School of Biological and Marine Sciences
Interspecific hybridization can lead to myriad outcomes, including transgressive phenotypes in which the hybrids are more fit than either parent species. Such hybrids may display important traits in the context of climate change, able to respond to novel environmental conditions not previously experienced by the parent populations. While this has been evaluated in an agricultural context, the role of transgressive hybrids under changing conditions in the wild remains largely unexplored; this is especially true regarding transgressive gene expression. Using the blue mussel species complex (genus Mytilus) as a model system, we investigated the effects of hybridization on temperature induced gene …
Do I Sound Anxious? Emotional Arousal Is Linked To Changes In Vocalisations In Domestic Chicks (Gallus Gallus Dom.), Sarah A. Collins, Katherine Herborn, Kenneth J. Sufka, Lucy Asher, Ben Brilot
Do I Sound Anxious? Emotional Arousal Is Linked To Changes In Vocalisations In Domestic Chicks (Gallus Gallus Dom.), Sarah A. Collins, Katherine Herborn, Kenneth J. Sufka, Lucy Asher, Ben Brilot
School of Biological and Marine Sciences
A major goal in animal welfare science is the development of methods that quantify or ‘read-out’ current affective states in freely behaving animals. In mammalian models, changes in acoustic parameters within vocalisations have been linked to differences in emotional arousal, although there are very few studies showing changes in vocalisations that act as indicators of valence (positive or negative affect). Currently, there are very few studies on vocal indicators of emotion in birds. To determine the link between acoustic parameters within vocalisations and emotion in domestic chicks (Gallus gallus dom.), we used a well-validated paradigm that purports to elicit two …
Integration Of Attractive And Defensive Phytochemicals Is Unlikely To Constrain Chemical Diversification In A Perennial Herb, Hanna Eriksdotter Thosteman, Katherine Eisen, Hampus Petrén, Sotiria Boutsi, Loretta Pace, John M. Halley, Consuelo M. De Moraes, Mark C. Mescher, James Buckley, Magne Friberg
Integration Of Attractive And Defensive Phytochemicals Is Unlikely To Constrain Chemical Diversification In A Perennial Herb, Hanna Eriksdotter Thosteman, Katherine Eisen, Hampus Petrén, Sotiria Boutsi, Loretta Pace, John M. Halley, Consuelo M. De Moraes, Mark C. Mescher, James Buckley, Magne Friberg
School of Biological and Marine Sciences
Diversification of plant chemical phenotypes is typically associated with spatially and temporally variable plant–insect interactions. Floral scent is often assumed to be the target of pollinator-mediated selection, whereas foliar compounds are considered targets of antagonist-mediated selection. However, floral and vegetative phytochemicals can be biosynthetically linked and may thus evolve as integrated phenotypes. Utilizing a common garden of 28 populations of the perennial herb Arabis alpina (Brassicaceae), we investigated integration within and among floral scent compounds and foliar defense compounds (both volatile compounds and tissue-bound glucosinolates). Within floral scent volatiles, foliar volatile compounds, and glucosinolates, phytochemicals were often positively correlated, and …
The Embryonic Thermal Environment Has Positive But Weak Effects On Thermal Tolerance Later In Life In The Aquatic Invertebrate Gammarus Chevreuxi, Honor Haskett, Luke Gill, John I. Spicer, Manuela Truebano
The Embryonic Thermal Environment Has Positive But Weak Effects On Thermal Tolerance Later In Life In The Aquatic Invertebrate Gammarus Chevreuxi, Honor Haskett, Luke Gill, John I. Spicer, Manuela Truebano
School of Biological and Marine Sciences
Recent evidence suggests that the adult phenotype is influenced by temperatures experienced in early life. However, our understanding of the extent to which the embryonic environment can modulate thermal tolerance later in life is limited, owing to the paucity of studies with appropriate experimental designs to test for this form of developmental plasticity. We investigated whether the thermal environment experienced during embryonic development affects thermal limits in later life. Embryos of the estuarine amphipod Gammarus chevreuxi were incubated until hatching to 15 °C, 20 °C and 25 °C, then reared under a common temperature. Using thermal ramping assays, we determined …
Invasive Macroalgae In Native Seagrass Beds: Vectors Of Spread And Impacts, Louise Firth, Andy Foggo, Thomas Watts, Antony Knights, Stacey Deamicis
Invasive Macroalgae In Native Seagrass Beds: Vectors Of Spread And Impacts, Louise Firth, Andy Foggo, Thomas Watts, Antony Knights, Stacey Deamicis
School of Biological and Marine Sciences
Background and AimsWorldwide, invasive species are spreading through marine systems at an unprecedented rate with both positive and negative consequences for ecosystems and the biological functioning of organisms. Human activities from shipping to habitat damage and modification are known vectors of spread, although biological interactions including epibiosis are increasingly recognized as potentially important to introduction into susceptible habitats.MethodsWe assessed a novel mechanism of spread – limpets as transporters of an invasive alga, Sargassum muticum, into beds of the seagrass Zostera marina – and the physiological impact of its invasion. The association of S. muticum with three limpet species and other …

This study presents the first comprehensive analysis of anthropogenic debris on the riverbanks of the Ciliwung River, covering upstream to downstream areas. The mean of debris found in each measurement was 32.79 ± 15.38 items/m2 with a weight of 106.00 ± 50.23 g/m2. Plastic debris accounted for over 50 % of all litter items identified and represents 55 % by weight, signifying a significantly high prevalence compared to global studies examining litter along riverbanks. The majority of the plastics found originated from Single-use applications and were predominantly made from Styrofoam. This investigation demonstrated the importance of actions …
Victim Of Changes? Marine Macroalgae In A Changing World, Mick E. Hanley, Louise B. Firth, Andy Foggo
Victim Of Changes? Marine Macroalgae In A Changing World, Mick E. Hanley, Louise B. Firth, Andy Foggo
School of Biological and Marine Sciences
Background Marine macroalgae (‘seaweeds’) are a diverse and globally distributed group of photosynthetic organisms that together generate considerable primary productivity, provide an array of different habitats for other organisms, and contribute many important ecosystem functions and services. As a result of continued anthropogenic stress on marine systems, many macroalgal species and habitats face an uncertain future, risking their vital contribution to global productivity and ecosystem service provision. Scope After briefly considering the remarkable taxonomy and ecological distribution of marine macroalgae, we review how the threats posed by a combination of anthropogenically induced stressors affect seaweed species and communities. From there …

The challenge of managing aquatic connectivity in a changing climate is exacerbated in the presence of additional anthropogenic stressors, social factors, and economic drivers. Here we discuss these issues in the context of structural and functional connectivity for aquatic biodiversity, specifically fish, in both the freshwater and marine realms. We posit that adaptive management strategies that consider shifting baselines and the socio-ecological implications of climate change will be required to achieve management objectives. The role of renewable energy expansion, particularly hydropower, is critically examined for its impact on connectivity. We advocate for strategic spatial planning that incorporates nature-positive solutions, ensuring …

Amplifying Pcr Productivity And Environmental Sustainability Through Shortened Cycling Protocols, Matthew Pedlar, Matthew J. Emery, Philip J. Warburton
School of Biological and Marine Sciences
Since its inception in the 1980s, advancements in PCR technology using improved thermal cyclers, engineered DNA polymerases and commercial master mixes, have led to increased PCR productivity. Despite these advancements, PCR cycling protocols have largely remained unchanged over the same period. This study aimed to systemically evaluate the effect of reduced PCR cycling parameters on amplicon production. The 1466bp fragment from the 16S rRNA gene present in low-, medium- and high-CG bacteria was amplified using three commercially available PCR master mixes. The shortest cycling parameters required to successfully amplify the 16S fragment from all bacteria and master mixes comprised 30-cycles …
Shifting The Focus From Species To Individuals In Invasion Biology: Individual Differences In Jumping Behaviour, Aaron Jessop, Miguel Barbosa, Michael Morrissey
Shifting The Focus From Species To Individuals In Invasion Biology: Individual Differences In Jumping Behaviour, Aaron Jessop, Miguel Barbosa, Michael Morrissey
School of Biological and Marine Sciences
Dispersal is critical to population persistence, colonization and connectivity which are all critical components of invasive success. While individual propensity to disperse varies within populations, the underlying mechanisms promoting individual dispersal remain unclear. Collectively, dispersal is influenced by the environment and individual phenotype. Here we investigated individual dispersal propensity in the Trinidadian guppy, Poecilia reticulata, and related individual variation in dispersal behaviour to phenotype and social/environmental conditions. Namely, we addressed the effect of sex ratio (social/environmental factor) on the tendency for individuals to disperse across physical barriers via jumping behaviour. Jumping is vital for the dispersal of many aquatic species …

Electrochemical Based Quantification Of Bacterial Growth In Media Using Square Wave Voltammetry And Low Cost Screen Printed Electrodes, Simon Peter Whelan, Shirin Naserikarimvand, Zari Tehrani, Martin Peacock, Owen Guy, David Gethin
School of Geography, Earth and Environmental Sciences
A novel method for determining the yield of bacterial growth using square wave voltammetry and screen printed electrodes is described here. This procedure was shown to be a reliable and accurate way to quickly determine the level of bacterial growth within culturing media and these results suggest that the combination of such sensors and the application of square wave voltammetry is suitable for applications such as within a bioreactor where the rapid determination of bacterial growth may be necessary.

Blood From A Stone: Do The Trace Metals Of Sperm Whale Coproliths Reveal A Contribution From Squid Haemolymph?, Steven J. Rowland, Robert Clough, Paul A. Sutton, George H. Rowland
School of Geography, Earth and Environmental Sciences
Background: Ambergris is a coprolith produced by some sperm whales (∼1 %). It has been hypothesised that the metals in ambergris derive from the haemolymph of squid in the whale diet (mainly copper). However, few data exist. We report analysis of 10 trace metals in each of 50 ambergris samples by inductively coupled plasma-mass spectrometry. Main Findings: Acid digests of the samples contained ∼5 to >6880 µg g−1 air-dried weight total metals; mainly of iron (present in ∼90 % of samples, 38), copper (∼95 % of samples, 40), zinc (93 % of samples, 39) and cadmium (∼95 % of …
Guidelines For Protecting And Promoting Decapod Crustacean Welfare In Research, Mark Briffa
Guidelines For Protecting And Promoting Decapod Crustacean Welfare In Research, Mark Briffa
School of Biological and Marine Sciences
The decapod order contains ~15,000 species, including crabs, lobsters, crayfish, prawns, and shrimps. The idea that these animals might experience pain was long dismissed because they were thought to respond to noxious stimuli and tissue damage purely by nociceptive reflex—a position questioned by Sherwin (2001). Later experimental studies demonstrated that their responses were complex, long-lasting, and largely consistent with criteria for pain that had been produced initially for vertebrates (Elwood 2019). While the nature and extent of potential sentience in decapods remains an active area of research, these animals were recently recognized as sentient for the purposes of UK law, …

As a land-locked country in Southern Africa, Zambia is rich in natural resources suitable for fish production. However, aquaculture is still in its infancy with enormous potential as most of Zambia’s fish now comes from capture fisheries. The aim of this study was to review the recent progress, status, challenges, and opportunities in Zambia’s aquaculture industry while drawing some lessons from China’s aquaculture experience, focusing on policy instruments, external support, quality seeds, and the investment environment for possible adaptation. To achieve this, we reviewed the existing literature about aquaculture in Zambia. This paper starts by reviewing the overall fishery sector’s …

Low-fishmeal and protein-saving diets are two prominent nutritional strategies utilized to address challenges related to the scarcity and sustainability of protein sources in aquaculture. However, these diets have been associated with adverse effects on the growth performance, feed utilization, and disease resistance of aquatic animals. To mitigate these challenges, exogenous protease has been applied to enhance the quality of diets with lower protein contents or fishmeal alternatives, thereby improving the bioavailability of nutritional ingredients. Additionally, protease preparations were also used to enzymatically hydrolyze fishmeal alternatives, thus enhancing their nutritional utilization. The present review aims to consolidate recent research progress on …

Phenomics is the acquisition of high-dimensional data on an individual-wide scale and is proving transformational in areas of biological research related to human health including medicine and the crop sciences. However, more broadly, a lack of accessible transferrable technologies and research approaches is significantly hindering the uptake of phenomics, in contrast to molecular-omics for which transferrable technologies have been a significant enabler. Aquatic embryos are natural models for phenomics, due to their small size, taxonomic diversity, ecological relevance, and high levels of temporal, spatial and functional change. Here, we present LabEmbryoCam, an autonomous phenotyping platform for timelapse imaging of developing …

Seagrasses impact on sedimentary intertidal and subtidal ecosystems by affecting local hydrodynamics, geomorphology and sediment properties. Their influence on hydrodynamics is to reduce flow velocities in their canopies, and this leads to increased net sedimentation rates and reduction of the grain size. Most investigations of the seagrass-hydrodynamics-sediment feedback system has been carried out over silt and fine-sand beds under tide-dominated conditions, mostly in the intertidal zone. Here, we use sedimentological data from a relatively wave-exposed and subtidal seagrass (Zostera marina) meadow in the Isles of Scilly with a fine-to-medium sand bed and show that the sand within the seagrass meadow …

A growing body of critical care research draws on real-world data from electronic health records (EHRs). The bedside clinician has myriad data sources to aid in clinical decision-making, but the lack of data sharing and harmonization standards leaves much of this data out of reach for multi-institution critical care research. The Society of Critical Care Medicine (SCCM) Discovery Data Science Campaign convened a panel of critical care and data science experts to explore and document unique advantages and opportunities for leveraging EHR data in critical care research. This article reviews and illustrates six organizing topics (data domains and common data …

PURPOSE: To study the dosimetric impact of incorporating variable relative biological effectiveness (RBE) of protons in optimizing intensity-modulated proton therapy (IMPT) treatment plans and to compare it with conventional constant RBE optimization and linear energy transfer (LET)-based optimization.
METHODS: This study included 10 pediatric ependymoma patients with challenging anatomical features for treatment planning. Four plans were generated for each patient according to different optimization strategies: (1) constant RBE optimization (ConstRBEopt) considering standard-of-care dose requirements; (2) LET optimization (LETopt) using a composite cost function simultaneously optimizing dose-averaged LET (LET
RESULTS: We found that the LETopt plans consistently achieved increased LET in …

Introduction: Vestigial-like 1 (VGLL1) is a co-transcriptional activator that binds to TEA domain-containing transcription factors (TEADs). Its expression is upregulated in a variety of aggressive cancer types, including pancreatic and basal-like breast cancer, and increased transcription of VGLL1 is strongly correlated with poor prognosis and decreased overall patient survival. In normal tissues, VGLL1 is most highly expressed within placental trophoblast cells, which share the common attributes of rapid cellular proliferation and invasion with tumor cells. The impact of VGLL1 in cancer has not been fully elucidated and no VGLL1-targeted therapy currently exists.
Methods: The aim of this study was to …
