Tuff life: Bioalteration in volcaniclastic rocks from the Ontong Java Plateau

We report microscopic textural, geochemical, isotopic, and biomolecular evidence for microbial alteration of glass shards in a 337.7 m thick sequence of poorly sorted vitric and lithic tuffs recovered during Leg 192 of the Ocean Drilling Program on the Ontong Java Plateau. Petrographic analysis has revealed the highest density and variety of exceptionally preserved microbial alteration textures in the glass shards, when compared to previous studies of glassy pillow basalt margins from ocean crust and ophiolites. Two textural types of microbial alteration are commonly observed: tubular and granular. Tubular textures are characterized by well‐preserved, micron‐scale, tubular to vermicular, channel‐like features with both smooth and scalloped walls that commonly extend from a granular alteration interface rimmed by clay into unaltered glass. These channels are highly convoluted or twisted and in some instances bifurcate. Detailed scanning electron microscopy (SEM) images reveal the presence of delicate filaments and desiccated thin films with morphologies suggestive of a biogenic origin within the channels. Granular textures appear as solid bands, semicircles, or irregular patches of individual and/or coalesced spherical bodies with irregular protrusions into fresh glass. Microprobe X‐ray element maps show elevated levels of carbon, nitrogen, phosphorous, and potassium associated with the microbial alteration features. Bulk‐rock carbon isotope ratios of disseminated carbonates in tuffs preserving fresh glass are depleted (<−9‰), suggesting biologic fractionation. The presence of nucleic acids within the microbial alteration features has been confirmed though staining with ethidium bromide, a stain that specifically binds to double‐stranded DNA and RNA. The presence of DNA/RNA suggests that the biogenic features may be relatively recent and that microbes may be currently active.
Conservation Targets in South American Temperate Forests

An important near-term goal of the international conservation agenda is to double the average percentage of land area currently protected in each nation to 10%. The effectiveness of this initiative is evaluated in endemic-rich temperate forests of southern Chile, where 29% of the regional land is under protection. Here biodiversity continues to be at risk because the areas of highest biodiversity remain largely unprotected and are immersed in a heavily managed anthropogenic matrix.
Online harassment

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings Online harassment and cyberbullying is on the increase in the workplace. Cyberbullying can be anonymous, widespread and permanently online. This causes much mental stress and distress for the victim, leading to a reduction in personal resources such as time and energy while they deal with the threat. This leads to decreased motivation, reduced job satisfaction, and potential intent to leave the company. This effect is gendered, with females more likely to report higher perceived stress and job dissatisfaction than males. Companies need to have comprehensive and transparent gender-specific policies in place to reduce workplace stress and increase employee job satisfaction. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.
Improving Stroke Documentation on a Stroke Unit

The aim of this project is to improve adherence of stroke documentation per stroke protocols on a stroke unit at an acute hospital setting through nursing education and EPIC modifications. A comprehensive retrospective data collection was done to determine the inconsistencies of nursing documentation per organizational protocols. Firstly, a randomized sample of 163 stroke patients (Site 1 = 98; Site 2 = 65) was generated for retrospective data collection. For this project, the main focus was Site 1 (n = 98). The sample from Site 1 consisted of 4 types of stroke patients, which were patients who either received alteplase (TPA= 19); did not receive alteplase (NTPA= 34); had Intracerebral Hemorrhagic Stroke (ICH= 30); or were suspected of stroke/ Transient Ischemic Attack (TIA= 15). Next, stroke chart audits were done to determine whether or not the nursing documentation was consistent per stroke protocol. The goal of this retrospective data analysis was to recognize areas where there are charting inconsistencies; lacks of adherence to the organization’s stroke protocols, and recommend interventions to improve nursing stroke documentation. Results from this retrospective data analysis demonstrate the need to educate nurses on the importance of accurate and consistent documentation along with the legal implications if non- compliant with standard protocols. In addition, there is a need to modify EPIC to enforce stroke protocols and increase nurses’ compliance rates.
Evolving subglacial water systems in East Antarctica from airborne radar sounding

Subglacial lakes in East Antarctica can be separated into four categories specified by radar reflection properties. Definite lakes are brighter than their surroundings by at least 2 dB (relatively bright) and are both consistently reflective (specular) and have a reflection coefficient greater than –10 dB (absolutely bright). Dim lakes are relatively bright and specular but not absolutely bright, indicating nonsteady ice dynamics. Fuzzy lakes are both relatively and absolutely bright but not specular, and may indicate saturated sediments or “swamps”. Indistinct lakes are absolutely bright and specular but no brighter than their surroundings. Lakes and the different classes of lakes are not arranged randomly throughout Antarctica but are clustered around ice divides, ice stream onsets, and prominent bedrock troughs, with each cluster demonstrating a different characteristic-lake-classification distribution. The lake-classification algorithm expands on previous studies and demonstrates a novel and improved way to characterize ice-water interactions in East Antarctica (Peters et al., 2005; Tabacco et al., 2006).
Radiocarbon in Dissolved Organic and Inorganic Carbon From the Central North Pacific

Radiocarbon measurements are reported for dissolved organic carbon (DOC) and inorganic carbon (DIC) from seawater samples collected from the Alcyone-5 cruise in the central North Pacific Ocean in 1985. Differences between the UV-radiation techniques used here and those reported by Williams, Oeschger and Kinney (1969) to oxidize and recover the DOC from sea water are presented. UV unoxidizable DOC in these samples is discussed in a separate publication (Druffel, Williams & Suzuki, 1989). We briefly discuss the penetration of the bomb 14C signal into the DOC and DIC pools. The temporal variability of Δ 14C in DIC in surface samples taken every 2–3 days is presented. Concentrations of total dissolved free (FAA) plus combined (hydrolyzable) amino acids (THAA) and total dissolved carbohydrates (TCHO) measured in the same water samples are also reported. Our main aim is to present the chemical and isotopic data from samples collected during the Alcyone-5 cruise. Detailed interpretation is published elsewhere.

Trace metal contamination in a Mediterranean coastal pond (Acquatina, Puglia)

1 - As the interface between land and sea, transitional areas are often negatively impacted by anthropic activities. This impact is the result of many processes, including direct input of pollutants which accumulate in both sediments and aquatic organisms. 2 - The aim of this paper is to identify trace metal (As, Cd, total Hg and Pb) contamination in the Acquatina pond (Apulia, Italy), using sediment and fish (A. boyeri, C. labrosus, D. annularis, D. dentex,, D. sargus, D. vulgaris, E. encrasicholus, G. paganellus, L. ramada, M. surmuletus, S. salpa, S. solea) as descriptors. Sampling was carried out in three stations (South, Central and North) and four seasons (summer and autumn 2007, winter and spring 2008). Fish metal concentrations were correlated with a15N values, which is an indicator of their trophic position. 3 - Both sediment and fish trace metal concentrations were compared with regulatory limits. Results showed that trace metal concentrations in sediment were comparable to levels found in moderately contaminated areas. The North station was more contaminated, probably because of freshwater discharges through the Giammatteo channel. 4 - Within ichthyofauna, higher metal levels were found in demersal fish. A significant relationship between trace metal and a15N was found only in total Hg in demersal fish.
Atlantic Ocean Circulation at the Last Glacial Maximum: Inferences from Data and Models

This thesis focuses on ocean circulation and atmospheric forcing in the Atlantic Ocean at the Last Glacial Maximum (LGM, 18-21 thousand years before present). Relative to the pre-industrial climate, LGM atmospheric CO₂ concentrations were about 90 ppm lower, ice sheets were much more extensive, and many regions experienced significantly colder temperatures. In this thesis a novel approach to dynamical reconstruction is applied to make estimates of LGM Atlantic Ocean state that are consistent with these proxy records and with known ocean dynamics. Ocean dynamics are described with the MIT General Circulation Model in an Atlantic configuration extending from 35°S to 75°N at 1° resolution. Six LGM proxy types are used to constrain the model: four compilations of near sea surface temperatures from the MARGO project, as well as benthic isotope records of [delta]¹⁸O and [delta]¹³C compiled by Marchal and Curry; 629 individual proxy records are used. To improve the fit of the model to the data, a least-squares fit is computed using an algorithm based on the model adjoint (the Lagrange multiplier methodology). The adjoint is used to compute improvements to uncertain initial and boundary conditions (the control variables). As compared to previous model-data syntheses of LGM ocean state, this thesis uses a significantly more realistic model of oceanic physics, and is the first to incorporate such a large number and diversity of proxy records. A major finding is that it is possible to find an ocean state that is consistent with all six LGM proxy compilations and with known ocean dynamics, given reasonable uncertainty estimates. Only relatively modest shifts from modern atmospheric forcing are required to fit the LGM data. The estimates presented herein succesfully reproduce regional shifts in conditions at the LGM that have been inferred from proxy records, but which have not been captured in the best available LGM coupled model simulations. In addition, LGM benthic [delta]¹⁸O and [delta]¹³C records are shown to be consistent with a shallow but robust Atlantic meridional overturning cell, although other circulations cannot be excluded.
Revisiting Peter Macklem's old dream through the PRISm of lung volumes

Tweetable abstract In the 1960s, Peter Macklem and, later, Sonia Buist shared the vision of a marker to identify smokers who will progress to COPD based on small airway function assessment [1–3]. While this discussion has continued, the unmet need of prediction remains the same. Tweetable abstract In healthy asymptomatic smokers with normal FEV1/FVC, abnormal CT lung volumes that reflect small airway dysfunction and emphysema could be used as a biomarker to identify susceptible smokers at increased risk of progressing to COPD https://bit.ly/3XZDj1s
Regional Exploration Targeting Model for Gangdese Porphyry Copper Deposits

An exploration targeting model for Gangdese porphyry copper deposit in Tibet, China, is constructed based on (i) the age of porphyry intrusions within Gangdese magmatic arc; (ii) the regional‐scale normal E–W, N–S and N–E striking faults; and (iii) comprehensive anomalously high concentrations of Cu‐Mo‐Au‐Ag‐Pb‐Zn. These targeting elements are derived from geological map and geochemical dataset, and are integrated by weights of evidence with the aid of geographic information system (GIS). The resulting prospectivity for porphyry copper deposits delineated by posterior probability demonstrates that the target areas extend along the Yaluzangbujiang River and contain the two large deposits, Qulong and Chongjiang, located in the eastern and central part of the Gangdese belt, respectively. These results indicate that the proposed exploration targeting model is a potential tool to map regional‐scale mineral prospectivity. The target areas with high values of favorability, especially where high concentrations of Cu‐Mo‐Au‐Ag‐Pb‐Zn are present, are the potential areas for finding undiscovered porphyry copper deposits.
Desarrollo turístico y comunidad local. Valoraciones y expectativas de los residentes de Ilhéus-BA, Brasil

Tourism Development and Local Community. Appraisals and Expectations of the Residents of Ilheus/BA, Brazil. The aim of this research was to build an analytical scenario based on the appraisals and expectations of tourism by the inhabitants of the city of Ilheus-BA The collected data showed that Ilheus' population expects the growing of tourism and that its benefits are distributed. However, this community is neither prepared to deal with the resulting effects of the activity, nor wishes to have significant changes of their ordinary life. Due to the lack of maturity of the local tourism, the managers still face a scenario with few problems to be solved.
Wavy Lineaments on Europa: Fracture Propagation into Combined Nonsynchronous and Diurnal Stress Fields

Understanding the processes that have operated on Europa and the manner in which they may have changed through time is fundamental to understanding the satellite's geology and present-day habitability. Previous studies have shown that lineament patterns on Europa can be explained by accumulation of tensile stress from slow nonsynchronous rotation (NSR), while the cycloidal planforms of other Europan lineaments can be explained if fractures propagate through a diurnally changing tensile stress field. We find that fractures propagated into combined diurnal and NSR stress fields can be "wavy" in planform for NSR stress accumulated over ~2 to 8 of ice shell rotation and average propagation speeds of approx. 1 to 3 m/s. The variety of Europa's observed lineament planforms from cycloidal, to wavy, to arcuate can be produced by accumulation of NSR stress relative to the diurnal stress field. Varying proportions of these stress mechanisms plausibly may be related to a time-variable (slowing) NSR rate.
Influence of bedding dip on glacial erosional landforms, uinta mountains, usa

Abstract We explore the relationships amongst bedding dip, basin aspect, and glacial landforms using field observations and analyses of the northwestern inta ountains of tah. We examine basins on opposing sides of three ice divides in which quartzite beds of the Mount Watson Formation maintain a near constant dip. These areas provide contrasting relationships between ice flow and bedding dip directions while holding rock type and climate constant. We map the occurrence of three glacial erosional landforms: cliffs showing evidence of quarrying, scoured surfaces polished by abrasion, and overdeepenings. Cliffs and overdeepenings are more common in basins where bedding dips up‐basin, while scoured surfaces are more prevalent where bedding dips down‐basin. The significance of jointing in controlling glacial erosional forms is well established and we propose that bedding, as well as joints, dictates the geometry of quarried blocks and influences the spatial patterns of process dominance. Where bedding dips up‐basin, the geometry of pre‐existing weaknesses favours quarrying creating both cliffs and overdeepenings. In contrast, where bedding dips down‐basin, block geometry does not favour the creation of overdeepenings via quarrying and exposed bedding planes are subjected to glacial abrasion, producing scoured surfaces.
New evidence on the slip rate, renewal time, and late Holocene surface displacement, southernmost San Andreas Fault, Mecca Hills, California

We estimate a renewal time for large earthquakes on the southernmost San Andreas fault (SAF) of 260 ± 100 years based on new paleoseismological data and a 34 millennia slip rate of 5–8 mm/yr. Our mean recurrence interval, 260 ± 100, is longer and its variance is smaller than the 160 + 240/–93 estimate for a M ≥7 earthquake used by the Working Group on California Earthquake Probabilities (WGCEP, 1995). A smaller creep rate than on contiguous 12-km fault segments is explained by Global Positioning System data that reveals 2–4 mm/yr of creep on the recently discovered Witbaard fault that bypasses the 12-km-long North Shore strand of the SAF. Geomorphic features near an archaeological site that cross the fault allow us to measure displacements of 155 ± 25 cm based on right-lateral gully offsets by the most recent earthquake (e.g., 1690). An Indian stone ring, straddling the fault trace, is currently offset 142 ± 12 cm. The ring lies on the 12-km-long North Shore segment of the SAF that has accumulated a minimum of 30 mm of triggered slip and aseismic creep since 1969. Contrasting slip rates of 23–35 mm/yr near Indio and 5–14 mm/yr on the southernmost SAF suggest that the Coachella Valley strand may be comprised of two distinct segments. Smaller long-term strain accumulation along the southernmost segment probably reduces earthquake potential for that area.

Continental water recycling and H218O concentrations

Using a GCM fitted with tracer diagnostics, we examine how continental moisture recycling affects the stable water isotope content of precipitation, focusing on its contribution to the “noise” in the well-established relationship between temperature and δ18O. On a global basis, for temperatures between −30° and 15°C, continental recycling explains more than a third of the variability in annual δ18O that is not explained by temperature. Recycling appears almost as important as temperature in defining δ18O distributions during northern hemisphere summer.
Geological applications of Nimbus radiation data in the Middle East

Plateaus of Eocene limestone and exposed limestone escarpments, in Egypt and Saudi Arabia respectively, were indicated by cool brightness temperatures T sub B (less than 240 to 265 K) by the Nimbus 5 electrically scanning microwave radiometer (ESMR) over a 2-year period. Nubian sandstone, desert eolian sand and igneous metamorphic rocks were differentiated from these limestone areas by warm T sub B values (more than 265 to 300 K). Cool T sub B values in the form of a V were found over broad areas of the Nile Valley and in the western desert of central Egypt. Similar cool T sub B values were shown over limestone-dolomitic hills of the interior Homocline and the Hadramawt plateau of Saudi Arabia. Nimbus 5 and 6 ESMR T sub B values selectively identified intermediate dense rock types (limestone versus sandstone/granite) in the Lake Nasser region whose thermal inertia ranged from 0.035 to 0.06 cal cm to minus 2 C sec 1/2 to minus one half.
Enhancing data quality in data warehouse environments

D ecisions by senior management lay the groundwork for lower corporate levels to develop policies and procedures for various corporate activities. However, the potential business contribution of these activities depends on the quality of the decisions and in turn on the quality of the data used to make them. Some inputs are judgmental, others are from transactional systems, and still others are from external sources, but all must have a level of quality appropriate for the decisions they will be part of. Although concern about the quality of one’s data is not new, what is fairly recent is using the same data for multiple purposes, which can be quite different from their original purposes. Users working with a particular data set come to know and internalize its deficiencies and idiosyncrasies. This knowledge is lost when data is made available to other parties, like when data needed for decision making is collected in repositories called data warehouses. Here, we offer a conceptual framework for enhancing data quality in data warehouse environments. We explore the factors that should be considered, such as the current level of data quality, the levels of quality needed by the relevant decision processes, and the potential benefits of projects designed to enhance data quality. Those responsible for data quality have to understand the importance of such factors, as well as the interaction among them. This understanding is mandatory in data warehousing environments characterized by multiple users with differing needs for data quality. For warehouses supporting a limited number of decision processes, awareness of these issues coupled with good judgment should suffice. For more complex situations, however, the number and diversity of trade-offs make reliance on judgment alone problematic. For such situations, we offer a methodology that Nothing is more likely to undermine the performance and business value of a data warehouse than inappropriate, misunderstood, or ignored data quality.
