This is a very dull book. Like a dictionary, it contains only facts: facts that are not readily to be found elsewhere. People who are important in the study of caves and karst are known for what they ...did, what they wrote and whom they influenced. But as individuals they are often no more than a name. They may perhaps be recognized for other aspects, as a King perhaps, or a novelist or a famous doctor. Some, like Darwin or Freud, have changed the world in other ways~but very many had only normal quiet lives during which they also explored, studied or wrote about caves. It is they whose wider lives are difficult to trace and it is 4634 of them who are recorded here, with information from birth certificates, obituaries, unpublished letters and mentions by other people. It is their wider lives that help to show them as real people. In some cases their interest in caves was a part of their professional lives. In many others it provides stimulation and relaxation in otherwise busy lives. But in every case it was the same person and the same brain that enjoyed both~and it was both that made them the people they were. It is only from the biographical sources recorded here, that each person can be understood.
In the knowledge economy, the 'creative industries' are recognised as a new paradigm. They are industries which use creativity as an intangible asset to generate wealth. The creative industries are ...described as 'evolving' and their outcomes frequently categorised as 'intangibles'. The thesis outlines what I term a creative industries approach to the engagement of visual artists with industry. The artist-in-industry program, a component of New Possibilities for Paper, was established with an explicit brief to generate creative products and contained an implicit agenda to breed intellectual capital. It was conceived as a means of crossfertilising hitherto siloed sectors -- an arts environment with entrenched attitudes towards the subsidy, proprietorship and authority of creativity and the traditionally conservative paper industry. Establishing creative industries characteristics and indicators to describe and measure creative industries operation in this program required careful consideration, with the characteristics and indicators selected able to recognise trends or changes. The analysis of the seven partnerships confirmed that the artistin-industry program is a creative industries approach upon which future programs between visual artists and the paper industry could be constructed. The research found that the creative industries processes in most need of being addressed, if visual artists are to maximise their benefits, included an understanding and utilisation of intellectual property, knowledge of commercialisation processes and a positive attitude towards commercialisation. For paper companies that invest in R&D, there is recognition that potential tangible and intangible benefits can result from engaging in such partnerships. Additionally, a partnership in which the artist's role (or service) is focused on the industry's customers and contributes to employee knowledge was seen as being of greatest value to the paper industry.
There is limited knowledge about cancer patients' experiences of uncertainty while waiting for genome sequencing results, and whether prolonged uncertainty contributes to psychological factors in ...this context. To investigate uncertainty in patients with a cancer of likely hereditary origin while waiting for genome sequencing results, we collected questionnaire and interview data at baseline, and at three and 12 months follow up (prior to receiving results). Participants (
= 353) had negative attitudes towards uncertainty (
= 4.03, SD 0.68) at baseline, and low levels of uncertainty at three (
= 8.23, SD 7.37) and 12 months (
= 7.95, SD 7.64). Uncertainty about genome sequencing did not change significantly over time

Semi-structured interviews revealed that while participants were motivated to pursue genome sequencing as a strategy to reduce their illness and risk uncertainty, genome sequencing generated additional practical, scientific and personal uncertainties. Some uncertainties were consistently discussed over the 12 months, while others emerged over time. Similarly, some uncertainty coping strategies were consistent over time, while others emerged while patients waited for their genome sequencing results. This study demonstrates the complexity of uncertainty generated by genome sequencing for cancer patients and provides further support for the inter-relationship between uncertainty and anxiety. Helping patients manage their uncertainty may ameliorate psychological morbidity.
Tumor mutation profiling (MP) is often conducted on tissue from biopsies conducted for clinical purposes (diagnostic tissue). We aimed to explore the views of patients with cancer on who should own ...tumor biopsy tissue, pay for its storage, and decide on its future use; and determine their attitudes to and predictors of undergoing additional biopsies if required for research purposes. In this mixed methods, cross-sectional study, patients with advanced solid cancers enrolled in the Molecular Screening and Therapeutics Program (n = 397) completed a questionnaire prior to undergoing MP (n = 356/397). A subset (n = 23) also completed a qualitative interview. Fifty percent of participants believed they and/or relatives should own and control access to diagnostic tissue. Most (65.5%) believed the government should pay for tissue preparation. Qualitative themes included (1) custodianship of diagnostic tissue, (2) changing value of tissue across time and between cultures, (3) equity regarding payment, and (4) cost-benefit considerations in deciding on additional biopsies. Policy and regulation should consider patient perspectives. Extension of publicly funded health care to include tissue retrieval for clinical trials should be considered.
Increased Arctic air temperatures and evaporative fluxes have coincided with more frequent and destructive high‐latitude wildfires. Arctic fires impact ecosystems and people, especially at the ...community‐level by degrading air quality, destroying agriculture, and threatening life and property. Central Eastern Interior (CEI) Alaska is one such region that has recently experienced the effects of wildfire activity related to warming air temperatures. To improve our ability to identify fire weather events and assess their potential for extreme outbreaks at actionable lead times relevant to fire weather forecasters and managers, new metrics and approaches need to be established and applied toward understanding the physical mechanisms underlying such wildland fire characteristics. Our study uses a new, regional atmospheric circulation metric, the Alaska Blocking Index (ABI), to describe midtropospheric air pressure around Alaska, which is subsequently related to CEI fire weather conditions at the Predictive Service Area (PSA) scale in climatological and extreme events frameworks. Of note, during years of high fire activity, Build‐Up Index (BUI) values tend to be anomalously high during the duff and drought phases across the CEI PSAs, though comparatively lower BUI values are still associated with high fire activity in the Tanana Zone‐South (AK03S) PSA. Likewise, extreme BUI values are strongly tied to high ABI values and well‐defined upper‐air ridging circulation patterns in the duff and drought periods. The statistical skill of mean daily ABI values in the 6–10 day period preceding extreme duff period BUI values is modest (τ2 > 14%) in the Upper Yukon Valley (AK02) PSA, a hotbed of wildland fire activity. Extremes in ABI and CEI BUI often occur in tandem, yielding regional predictability of upper‐air weather patterns and extremes and underlying surface weather conditions, by statistical and/or dynamical forecast models, imperative for local community and governmental organizations to effectively manage and allocate Alaska's fire weather resources.
This study applies a new version of the Alaska Blocking Index (ABI) and an existing surface weather metric, the Build‐Up Index (BUI), toward understanding atmospheric conditions that shape Central Eastern Interior Alaska's fire activity through the four phases—wind, duff, drought and diurnal—of the annual fire season.
During hibernation, thirteen-lined ground squirrels (
) regularly cycle between bouts of torpor and interbout arousal (IBA). Most of the brain is electrically quiescent during torpor but regains ...activity quickly upon arousal to IBA, resulting in extreme oscillations in energy demand during hibernation. We predicted increased functional capacity of brain mitochondria during hibernation compared with spring to accommodate the variable energy demands of hibernation. To address this hypothesis, we examined mitochondrial bioenergetics in the ground squirrel brain across three time points: spring (SP), torpor (TOR), and IBA. Respiration rates of isolated brain mitochondria through complex I of the electron transport chain were more than twofold higher in TOR and IBA than in SP (
< 0.05). We also found a 10% increase in membrane potential between hibernation and spring (
< 0.05), and that proton leak was lower in TOR and IBA than in SP. Finally, there was a 30% increase in calcium loading in SP brain mitochondria compared with TOR and IBA (
< 0.01). To analyze brain mitochondrial abundance between spring and hibernation, we measured the ratio of copy number in a mitochondrial gene (
) vs. a nuclear gene (
) in frozen cerebral cortex samples. No significant differences were observed in DNA copies between SP and IBA. These data show that brain mitochondrial bioenergetics are not static across the year and suggest that brain mitochondria function more effectively during the hibernation season, allowing for rapid production of energy to meet demand when extreme physiological changes are occurring.
Purpose
The introduction of comprehensive tumour genomic profiling (CGP) into clinical oncology allows the identification of molecular therapeutic targets. However, the potential complexity of ...genomic results and their implications may cause confusion and distress for patients undergoing CGP. We investigated the experience of advanced cancer patients receiving CGP results in a research setting.
Methods
Semi-structured interviews with 37 advanced cancer patients were conducted within two weeks of patients receiving CGP results. Interviewees were purposively sampled based on CGP result, cancer type, age and gender to ensure diversity. Themes were derived from interview transcripts using a framework analysis approach.
Results
We identified six themes: (1) hoping against the odds; (2) managing expectations; (3) understanding is cursory; (4) communication of results is cursory; (5) genomics and incurable cancer; and (6) decisions about treatment.
Conclusion
Despite enthusiasm regarding CGP about the hope it provides for new treatments, participants experienced challenges in understanding results, and acceptance of identified treatments was not automatic. Support is needed for patients undergoing CGP to understand the implications of testing and cope with non-actionable results.

Autoantibodies play an important role in the pathogenesis of SLE, and the diverse clinical manifestations of the disease are caused by the deposition of antibody-containing immune complexes in blood vessels, leading to inflammation in the kidney, brain, and skin. Direct pathogenic effects of the autoantibodies contribute to hemolytic anemia and thrombocytopenia.
During the past 20 years, many linkage and candidate-gene studies have been performed to identify genetic factors contributing to a susceptibility to SLE. For example, haplotypes carrying the HLA class II alleles DRB1*0301 . . .
Germline genome sequencing (GS) holds great promise for cancer prevention by identifying cancer risk and guiding prevention strategies, however research evidence is mixed regarding patient ...preferences for receiving GS results. The aim of this study was to discern preferences for return of results by cancer patients who have actually undergone GS. We conducted a mixed methods study with a cohort of cancer probands (n = 335) and their genetic relatives (n = 199) undergoing GS in a research setting. Both groups completed surveys when giving consent. A subset of participants (n = 40) completed semi-structured interviews. A significantly higher percentage of probands thought people would like to be informed about genetic conditions for which there is prevention or treatment that can change cancer risk compared to conditions for which there is no prevention or treatment (93% 311 versus 65% 216; p < 0.001). Similar results were obtained for relatives (91% 180 versus 61% 121; p < 0.001). Themes identified in the analysis of interviews were: (1) Recognised benefits of GS, (2) Balancing benefits with risks, (3) Uncertain results are perceived as unhelpful and (4) Competing obligations. While utility was an important discriminator in what was seen as valuable for this cohort, there was a variety of responses. In view of varied participant preferences regarding return of results, it is important to ensure patient understanding of test validity and identify individual choices at the time of consent to GS. The nature and value of the information, and a contextual understanding of researcher obligations should guide result return.
Clinical genomic sequencing warrants the investigation and potential development of family-centered communication interventions.
Preference-sensitive family communication strategies about genomic ...testing are needed.
Support needs should be assessed specific to clinical applications of genomic testing.
This study explored family communication about undertaking genomic sequencing, and intentions to communicate pertinent heritable results to family members.
Semi-structured interviews were conducted with cancer patients (n = 53) and their relatives (n = 20) who underwent germline genome sequencing or molecular tumor testing. Interviews were audio-recorded, transcribed and analyzed using thematic analysis.
Key themes relevant to family communication about undertaking sequencing included: perceiving family member interest, delaying discussion until results were received, having shared capacity to understand and cope, and having open communication in the family. Intended communication subsequent to receiving results was affected by: disease severity, risk management options, degree of closeness in the family, sense of responsibility, and potential adverse impacts on family. Resource and support needs varied based on the complexity of test results, health professionals’ availability, and disease severity. Unique subthemes were identified for specific subgroups.
Current findings support the need to assess the impact and resource needs specific to each clinical application of genomic sequencing.
Increasingly sophisticated and complex clinical genomic sequencing warrants development of family-centered interventions and resources to facilitate preference-sensitive communication about genomic sequencing, including disseminating relevant information to family members.
