Long-Term Recovery from Intimate Partner Violence: Recovery and Hope.

Recovery is a preferred outcome for assessing intervention effectiveness in the context of intimate partner violence (IPV), but measurement tools are in nascent form. It is therefore unclear what the recovery potential of survivors may be. A national online survey explored the self-rated recovery progress of Australian women (n = 1116), using visual analog scales (VAS) for recovery, hope, and other demographic variables. Findings show that many women rated themselves as completely recovered (14% of the eligible sample and 22% of the women who had left their partner > 10 years previously). However, most women experienced recovery as an ongoing process of healing (81%) and some women made little recovery progress (5%). Nevertheless, 77% of women who had separated >10 years ago rated their recovery as significant (scores of >70/100). Surprisingly, hope and recovery scores were only moderately correlated. This requires further investigation to determine what impacts on hope in long-term recovery, and how subjective and objective measures of hope and recovery vary in the context of IPV. The VAS was an efficient unidimensional measure for an online survey and is proposed for use in clinical and service contexts requiring subjective measures.

Weight gain stopping/switch rules for antiretroviral clinical trials.

Obesity develops in a substantial number of people initiating and maintaining modern antiretroviral therapy. The comorbidities associated with obesity make significant weight gain and metabolic changes a major consideration in clinical trials studying different regimens' potency and safety. It is as yet unclear what role individual antiretrovirals or classes play in weight gain but the issue is a complex one for clinical trial design, especially when deciding when "too much" weight has been gained, in a context where we do not yet know if switching to alternative regimens will slow, halt or reverse weight gain or metabolic changes. In addition, clinician and trial participant opinion on acceptable weight gain may differ. We offer preliminary guidance for discussion for future antiretroviral clinical trial design.

Fairness and accountability of AI in disaster risk management: Opportunities and challenges.

Disaster risk management (DRM) seeks to help societies prepare for, mitigate, or recover from the adverse impacts of disasters and climate change. Core to DRM are disaster risk models that rely heavily on geospatial data about the natural and built environments. Developers are increasingly turning to artificial intelligence (AI) to improve the quality of these models. Yet, there is still little understanding of how the extent of hidden geospatial biases affects disaster risk models and how accountability relationships are affected by these emerging actors and methods. In many cases, there is also a disconnect between the algorithm designers and the communities where the research is conducted or algorithms are implemented. This perspective highlights emerging concerns about the use of AI in DRM. We discuss potential concerns and illustrate what must be considered from a data science, ethical, and social perspective to ensure the responsible usage of AI in this field.

The limits of direct modulation of emotion for moral enhancement.

Assuming that moral enhancement is morally permissible, I contend that a more careful theoretical treatment of emotion and the affective landscape is needed to advance both our understanding and the prospects of interventions aimed at moral enhancement. Using Douglas' proposal for the direct modulation of counter-moral emotions as a foil for discussion, I argue that the direct modulation of emotion fails to address underlying aspects of an agent's psychology that will give rise to a range of counter-moral motives beyond the emotion that is targeted. This is because the direct modulation of emotion does not accommodate the fact that an emotional episode or emotional disposition is part of a network of other dispositions and responses, against a backdrop of our having cares and goals, as well as other cognitive content that can mediate how we apprehend a situation. By focusing on emotion rather than on moral capacity as other critiques have done, I thus argue that direct modulation is likely to be ineffective, and, more positively, by drawing out patterns of connections across the affective landscape, we can better tease out what it is that we should really be targeting if we are to achieve robust and meaningful moral change.

The Dictates of Conscience: Can They Justify Conscientious Refusals in Healthcare Contexts?

In a recent article in this journal, Steve Clarke (2017) identifies two different bases for conscience-based refusals in healthcare: (1) all-things-considered moral judgments, and (2) the dictates of conscience. He argues that these two bases have distinct roles in justifying conscientious objection. However, accepting that there are these two bases, I argue that both are not able to justify conscientious objection. In particular, I argue that the second basis of the dictates of conscience cannot justify conscience-based refusal in a healthcare context. Even if someone objects in a healthcare context on the basis of the dictates of her conscience, and even if we can explain why she objects with reference to the dictates of her conscience, her objection will only be justified if she makes a judgment.

Species-specific crab predation on the hydrozoan clinging jellyfish Gonionemus sp. (Cnidaria, Hydrozoa), subsequent crab mortality, and possible ecological consequences.

Here we report a unique trophic interaction between the cryptogenic and sometimes highly toxic hydrozoan clinging jellyfish Gonionemus sp. and the spider crab Libinia dubia. We assessed species-specific predation on the Gonionemus medusae by crabs found in eelgrass meadows in Massachusetts, USA. The native spider crab species L. dubia consumed Gonionemus medusae, often enthusiastically, but the invasive green crab Carcinus maenus avoided consumption in all trials. One out of two blue crabs (Callinectes sapidus) also consumed Gonionemus, but this species was too rare in our study system to evaluate further. Libinia crabs could consume up to 30 jellyfish, which was the maximum jellyfish density treatment in our experiments, over a 24-hour period. Gonionemus consumption was associated with Libinia mortality. Spider crab mortality increased with Gonionemus consumption, and 100% of spider crabs tested died within 24 h of consuming jellyfish in our maximum jellyfish density containers. As the numbers of Gonionemus medusae used in our experiments likely underestimate the number of medusae that could be encountered by spider crabs over a 24-hour period in the field, we expect that Gonionemus may be having a negative effect on natural Libinia populations. Furthermore, given that Libinia overlaps in habitat and resource use with Carcinus, which avoids Gonionemus consumption, Carcinus populations could be indirectly benefiting from this unusual crab-jellyfish trophic relationship.

Mitochondrial diversity in Gonionemus (Trachylina:Hydrozoa) and its implications for understanding the origins of clinging jellyfish in the Northwest Atlantic Ocean.

Determining whether a population is introduced or native to a region can be challenging due to inadequate taxonomy, the presence of cryptic lineages, and poor historical documentation. For taxa with resting stages that bloom episodically, determining origin can be especially challenging as an environmentally-triggered abrupt appearance of the taxa may be confused with an anthropogenic introduction. Here, we assess diversity in mitochondrial cytochrome oxidase I sequences obtained from multiple Atlantic and Pacific locations, and discuss the implications of our findings for understanding the origin of clinging jellyfish Gonionemus in the Northwest Atlantic. Clinging jellyfish are known for clinging to seagrasses and seaweeds, and have complex life cycles that include resting stages. They are especially notorious as some, although not all, populations are associated with severe sting reactions. The worldwide distribution of Gonionemus has been aptly called a "zoogeographic puzzle" and our results refine rather than resolve the puzzle. We find a relatively deep divergence that may indicate cryptic speciation between Gonionemus from the Northeast Pacific and Northwest Pacific/Northwest Atlantic. Within the Northwest Pacific/Northwest Atlantic clade, we find haplotypes unique to each region. We also find one haplotype that is shared between highly toxic Vladivostok-area populations and some Northwest Atlantic populations. Our results are consistent with multiple scenarios that involve both native and anthropogenic processes. We evaluate each scenario and discuss critical directions for future research, including improving the resolution of population genetic structure, identifying possible lineage admixture, and better characterizing and quantifying the toxicity phenotype.

Ascidiidae Herdman, 1882 (Tunicata: Ascidiacea) on the Pacific coast of Panama.

The ascidian fauna of the Pacific coast of Panama is poorly known and only recently four species in the family Ascidiidae were reported on. Ascidia is the only known genus of Ascidiidae in Pacific Panama waters. In the present research, we describe a new species, Ascidia sideralis sp. nov., and we document the new occurrence of A. cf. gemmata and A. cf. liberata (both previously known to the West Pacific), A. archaia (a cosmopolitan species elsewhere in the Pacific), A. ceratodes (previously documented in the eastern N. Pacific), and A. sydneiensis (an Atlantic species on the east coast of Panama) in Pacific Panama waters. A tabular key for the identification of Ascidiidae on the American Pacific coast complements this study.

Gluteal fascial advancement: an innovative, effective method for treating pilonidal disease.

The ideal elective surgical procedure for pilonidal disease is debated. Simple excision and closure is commonly performed but is associated with a high incidence of wound complications and recurrence. We developed a simple modification of primary closure, which involves the elevation, mobilization, and closure of the gluteal fascia. The purpose of this study is to compare outcomes of this gluteal fascial advancement technique with standard primary closure for the treatment of pilonidal disease. We retrospectively reviewed our surgical database to include all patients who underwent surgery for pilonidal disease from 2004 to 2007. Patients who underwent primary closure (n = 66) were compared with patients who underwent gluteal fascial advancement (n = 17). Demographic data as well as recurrence and the incidence of wound complications were examined. There was a significant difference in incidence of wound breakdown (0 vs 21%), recurrence (0 vs 20%), and early wound drainage (6 vs 32%). Overall there was an 80 per cent reduction in wound complications after gluteal fascial advancement compared with primary closure. Gluteal fascial advancement is a simple modification of standard primary closure and is associated with fewer wound complications and recurrences.

Layer-by-layer assembled films of cellulose nanowires with antireflective properties.

Natural nanowires (NWs) of cellulose obtained from a marine animal tunicate display surprisingly high uniformity and aspect ratio comparable with synthetic NWs. Their layer-by-layer assembled (LBL) films show strong antireflection (AR) properties having an origin in a novel highly porous architecture reminiscent of a "flattened matchsticks pile", with film-thickness-dependent porosity and optical properties created by randomly oriented and overlapping NWs. At an optimum number of LBL deposition cycles, light transmittance reaches nearly 100% (lambda approximately 400 nm) when deposited on a microscope glass slide and the refractive index is approximately 1.28 at lambda = 532 nm. In accordance with AR theory, the transmittance maximum red-shifts and begins to decrease after reaching the maximum with increasing film thickness as a result of increased light scattering. This first example of LBL layers of cellulose NWs can be seen as an exemplary structure for any rigid axial nanocolloids, for which, given the refractive index match, AR properties are expected to be a common property. Unique mechanical properties of the tunicate NWs are also a great asset for optical coatings.
