Eldercare, immigration, and health care in Italy: How the Italian state creates and mitigates inequality
Authors: Meyer Patti 
Published: June 2015

AbstractThis article considers the role of the Italian state as both a source of inequality and an institution that mitigates inequality. Fieldwork completed in Genoa in 2010 focused on the intersection of immigration policies, care work needs, and the informal economy revealed in the lives of immigrant in‐home care workers. Genoa, the largest city in the region of Liguria, is the “oldest” city in Europe, in that 33 percent of the population is now older than 60 years of age. In Esping‐Andersen's typology, Italy's Mediterranean‐familialist‐style welfare regime is characterized by a high dependence on family members to provide care, few state‐supported services for elders, and a shortage of policies that reconcile care and work. This combination places the burden of care for family elders on female relatives, thus perpetuating gender inequalities. In Italy, the relatives of the elder needing care often shift their burden onto low‐wage immigrant laborers. In households employing care workers in Genoa, examining how Italian state policies regarding eldercare maintain ethnic, class, and gender inequalities illustrates how state forces influence private realities. In addition, the well‐established practice of regional autonomy has transformed the Italian national health care system, as it is manifest in the region of Liguria, into a sociocultural institution that mitigates inequality in health care access as it serves both citizens and immigrants. However, this institution also supports unequal working conditions in that it supports informal economic activity by maintaining the health of the low‐wage, immigrant workforce critical to the well‐being of the elders of this region.

Published: June 2015

AbstractGreen fluorescent protein (GFP) has become an invaluable tool in biological research. Many GFP variants have been created that differ in brightness, photostability, and folding robustness. We have created two hybrid GFP variants, Envy and Ivy, which we placed in a vector for the C‐terminal tagging of yeast proteins by PCR‐mediated recombination. The Envy GFP variant combines mutations found in the robustly folding SuperfolderGFP and GFPγ, while the Ivy GFP variant is a hybrid of GFPγ and the yellow‐green GFP variant, Clover. We compared Envy and Ivy to EGFP, SuperfolderGFP and GFPγ and found that Envy is brighter than the other GFP variants at both 30°C and 37°C, while Ivy is the most photostable. Envy and Ivy are recognized by a commonly used anti‐GFP antibody, and both variants can be immunoprecipitated using the GFP TRAP Camelidae antibody nanotrap technology. Because Envy is brighter than the other GFP variants and is as photostable as GFPγ, we suggest that Envy should be the preferred GFP variant, while Ivy may be used in cases where photostability is of the utmost importance. The GenBank Accession No. for Envy is KM891731, for Ivy is KM891732 and for the yeast optimized GFPγ described in this paper is KM891733. Copyright © 2015 John Wiley & Sons, Ltd.
Boric acid destabilizes the hyphal cytoskeleton and inhibits invasive growth of Candida albicans
Authors: Pointer Benjamin R. , Boyer Michael P. , Schmidt Martin 
Published: June 2015

AbstractExposure of Candida albicans to sub‐lethal concentrations of boric acid (BA) restricts the dimorphic fungus to its yeast morphology and prevents the formation of invasive hyphae on solid substrates. Exposure to BA causes a rapid and reversible disappearance of polarisome and Spitzenkörper in growing hyphae. In BA‐treated hyphae of C. albicans, actin quickly reorganizes from cytoplasmic cables to cortical patches and cell wall growth switches from an apical to an isotropic pattern. As a result of the cytoskeletal changes, the hyphal tips broaden and directional growth of hyphae ceases in the presence of BA. An analysis of homozygous deletion strains showed that mutants with constitutive or enhanced hyphal growth (tup1, nrg1, ssn6, rbf1) are BA‐sensitive, demonstrating that cellular morphology is a major determinant of BA tolerance. The screening of deletion mutants also showed that deficiencies of the main activator of hyphal gene expression, Efg1, and the Rim101‐signalling cascade, leading to Efg1 activation, cause BA resistance. Taken together, the data presented show that the selective inhibitory effect on BA on C. albicans hyphae is rooted in a disruption of apical cytoskeletal elements of growing hyphae.

Reprogenetics, Genetic Tools and Reproductive Risk: Attitudes and Understanding Among Ethnic Groups in Israel
Authors: Simonstein Frida , Mashiach‐Eizenberg Michal 
Published: June 2015

AbstractThe present study investigated a possible relationship between the attitudes toward genetic technologies and the understanding of genetics, reproduction, and reproductive risk among Israeli Arabs and Israeli Jews. The study included 203 respondents, who answered a structured self‐report questionnaire. They were recruited using a snowball method, which increased the participation of Israeli Arabs in the sample, although the sample was not representative of the Israeli population as a whole (there were more Arabs and fewer men). The respondents in this study expressed a positive attitude toward genetic technologies, but were less in favor of using genetic tools for non‐medical purposes. Respondents of both groups were not knowledgeable of genetics; however, they scored higher on the items related to reproductive risk, which suggests that some awareness about genetic risk exists in both sectors of the Israeli population. Nevertheless, Israeli Arabs were less positive than Israeli Jews regarding the application of genetic tools. Moreover, although an understanding of genetics correlated positively with the attitude among Arabs, it did not affect the attitude of Jews, who remained very positive, regardless of their level of understanding. This result suggests that other social and cultural factors, besides understanding, might be at work among these two major ethnic sectors. Further studies that integrate educational, social, and cultural aspects among ethnic sectors of the population are required to improve health services and genetic counselling in Israel and in other countries.

Background Convention dictates that an axillary view be obtained when evaluating proximal humerus fractures (PHF). However, the axillary view is frequently omitted because of pain and technical considerations. Furthermore, its diagnostic utility is unclear in this setting. Questions/Purposes The purpose of this study was to (1) determine the rate of obtaining an adequate axillary X-ray and complete shoulder series at a level I trauma center, (2) understand the cost of ordering and attempting an axillary radiograph, and (3) determine if axillary radiographs influence the management of PHF. Patients and Methods PHF treated between 2009 and 2011 that were ordered for an AP, scapular Y, and axillary view was identified. The types of radiographs actually obtained were recorded. The cost of obtaining three views and a single view of the shoulder with X-ray was determined. Lastly, three surgeons reviewed 42 PHF, both with and without an axillary view (AV), and treatment recommendations were compared. Results 30% of PHF in this series had an adequate axillary view, and 14% received a complete trauma series. No factors could be identified that were associated with successfully obtaining an axillary view. Reviewers demonstrated substantial intraobserver reliability (κ = 0.759–0.808) regarding treatment recommendations for PHF with and without the axillary view. The addition of the AV had minimal influence on treatment recommendations. Conclusion Considering that the axillary view for PHF is painful, labor-intensive, costly, and does not appear to provide additional diagnostic value, orthopedic surgeons can consider foregoing the use of the axillary view when evaluating and treating PHF, particularly if other advanced imaging is utilized.
Capillary Curves for Ex‐situ Washing of Oil‐Coated Particles

Published: June 2015

AbstractThe oil removal efficiency for the ex situ extraction of bitumen from oil sands, or ex situ washing of oil‐contaminated sand and related processes is determined by the balance of forces at the oil/water and solid/fluid interfaces. The objective of this work is to estimate the balance of forces at the interface using dimensionless numbers, and their use in evaluating and engineering ex situ soil washing processes. To this end, bitumen was removed from bitumen‐coated sand particles using a two‐step process. In the first step, the particles were mixed with a suitable solvent (toluene) used, primarily, to reduce the viscosity of bitumen. The particles were then mixed with water or an aqueous surfactant solution capable of producing low interfacial tensions with the solvent‐bitumen mixture. The fraction of oil retained after washing was evaluated as a function of interfacial tension, solvent/bitumen ratio, mixing time, mixing velocity, and particle size. These ex situ washing conditions were normalized using dimensionless film and particle‐based Weber and Capillary numbers. The fraction of oil retained by the particles was plotted against these dimensionless numbers to generate capillary curves similar to those used in enhanced oil recovery. These curves reveal the existence of a critical film‐based Weber number and a particle‐based Capillary number that can be used in the design or evaluation of soil washing processes. The film‐based Weber number also explained literature data that associates interfacial tension with the removal of oil from oil‐based drill cuttings, as well as field observations on the role that particle size plays on the removal of oil in soil washing operations.
Managing for quality aged residential care with a migrant workforce
Authors: Ngocha-Chaderopa Nyemudzai Esther , Boon Bronwyn 
Published: June 2015

AbstractGiven the growing demand for aged residential care facilities in Western industrialised economies, the adequate staffing of these facilities is a growing concern. Increasingly migrant care workers are being employed to fill the local labour shortfall. In this paper we present findings of a qualitative study exploring how managers of aged residential care facilities work to ensure consistent delivery of quality care through their migrant care workers. The issues raised by the 16 managers cluster around three themes: communication and language barriers; racism by residents, families and managers; and underemployment of tertiary qualified migrant care workers. In addition to issues of quality care delivery, concerns around migrant employee well-being are seen to be difficult to avoid.
Acquirer Valuation and Acquisition Decisions: Identifying Mispricing Using Short Interest
Authors: Ben-David Itzhak , Drake Michael S. , Roulstone Darren T. 
Published: June 2015

AbstractWe use short interest as an investor-based measure of over- or undervaluation that distinguishes between the misvaluation and Q-theories of mergers. Using this measure, we find that misvaluation is a strong determinant of merger decision-making. Firms in the top quintile of short interest are 54% more likely to engage in stock acquisitions and 22% less likely to engage in cash acquisitions. Stock (but not cash) acquirers have higher short interest than their targets. Overall, our results suggest that the previously documented underperformance of stock acquirers and the overperformance of cash acquirers can be explained by misvaluation, as captured by short interest.
The Effects of Securities Class Action Litigation on Corporate Liquidity and Investment Policy
Authors: Arena Matteo , Julio Brandon 
Published: June 2015

AbstractThe risk of securities class action litigation alters corporate savings and investment policy. Firms with greater exposure to securities litigation hold significantly more cash in anticipation of future settlements and other related costs. The result is due to firms accumulating cash in anticipation of lawsuits and not a consequence of plaintiffs targeting firms with high cash levels. The market value of cash is lower for firms exposed to litigation risk. Corporate investment decisions are also affected by litigation risk, as firms reduce capital expenditures in response. Our results are robust to endogeneity concerns and possible spurious temporal effects.
Religion and Stock Price Crash Risk
Authors: Callen Jeffrey L. , Fang Xiaohua 
Published: June 2015

AbstractThis study examines whether religiosity at the county level is associated with future stock price crash risk. We find robust evidence that firms headquartered in counties with higher levels of religiosity exhibit lower levels of future stock price crash risk. This finding is consistent with the view that religion, as a set of social norms, helps to curb bad-news-hoarding activities by managers. Our evidence further shows that the negative relation between religiosity and future crash risk is stronger for riskier firms and for firms with weaker governance mechanisms measured by shareholder takeover rights and dedicated institutional ownership.
Dividend Yields, Dividend Growth, and Return Predictability in the Cross Section of Stocks
Authors: Maio Paulo , Santa-Clara Pedro 
Published: June 2015

AbstractThere is a generalized conviction that variation in dividend yields is exclusively related to expected returns and not to expected dividend growth, for example, Cochrane’s (2011) presidential address. We show that this pattern, although valid for the aggregate stock market, is not true for portfolios of small and value stocks, where dividend yields are related mainly to future dividend changes. Thus, the variance decomposition associated with the aggregate dividend yield has important heterogeneity in the cross section of equities. Our results are robust to different forecasting horizons, econometric methodology (long-horizon regressions or first-order vector autoregression), and alternative decomposition based on excess returns.
Social-psychological evidence for the effective updating of implicit attitudes
Authors: Mann Thomas C. , Cone Jeremy , Ferguson Melissa J. 
Published: June 2015

AbstractRecent findings in social psychology show how implicit affective responses can be changed, leading to strong, fast, and durable updating. This work demonstrates that new information viewed as diagnostic or which prompts reinterpretations of previous learning produces fast revision, suggesting two factors that might be leveraged in clinical settings. Reconsolidation provides a plausible route for making such reasoning possible.
Trade-offs between the accuracy and integrity of autobiographical narrative in memory reconsolidation
Authors: Montemayor Carlos 
Published: June 2015

AbstractLane et al. propose an integrative model for the reconsolidation of traces in their timely and impressive article. This commentary draws attention to trade-offs between accuracy and self-narrative integrity in the model. The trade-offs concern the sense of agency in memory and its role in both implicit and explicit memory reconsolidation, rather than balances concerning degrees of emotional arousal.
How do we remember traumatic events? Exploring the role of neuromodulation
Authors: Ortu Daniele 
Published: June 2015

AbstractThe seemingly puzzling datum that behavior decreases after punishing stimulation while individuals are still able to remember traumatic episodes is discussed in relation to dopaminergic and noradrenergic neuromodulation. The described mechanisms may contribute to an understanding of how occurrences of learning reconsolidation yield different outcomes across intra- and extra-therapeutic settings.
How does psychotherapy work? A case study in multilevel explanation
Authors: Roache Rebecca 
Published: June 2015

AbstractMultilevel explanations abound in psychiatry. However, formulating useful such explanations is difficult or (some argue) impossible. I point to several ways in which Lane et al. successfully use multilevel explanations to advance understanding of psychotherapeutic effectiveness. I argue that the usefulness of an explanation depends largely on one's purpose, and conclude that this point has been inadequately recognised in psychiatry.
Deconstructing the process of change in cognitive behavioral therapy: An alternative approach focusing on the episodic retrieval mode
Authors: Staniloiu Angelica , Zaretsky Ari E. 
Published: June 2015

AbstractLane et al. view the process of memory reconsolidation as a main ingredient of psychotherapeutic change. They ascertain that in cognitive behavioral therapy (CBT) high priority is given to the “semantic structure.” We argue that memory-related mechanisms of change in CBT are more nuanced than the target article presents. Furthermore, we propose to partially shift the focus from the process of reconsolidation to the retrieval operations.
Focus on emotion as a catalyst of memory updating during reconsolidation
Authors: Stein Maria , Rohde Kristina Barbara , Henke Katharina 
Published: June 2015

AbstractWe share the idea of Lane et al. that successful psychotherapy exerts its effects through memory reconsolidation. To support it, we add further evidence that a behavioral interference may trigger memory update during reconsolidation. Furthermore, we propose that – in addition to replacing maladaptive emotions – new emotions experienced in the therapeutic process catalyze reconsolidation of the updated memory structure.
Memory reconsolidation and psychotherapeutic process
Authors: Liberzon Israel , Javanbakht Arash 
Published: June 2015

AbstractLane et al. propose a heuristic model in which distinct, and seemingly irreconcilable, therapies can coexist. Authors postulate that memory reconsolidation is a key common neurobiological process mediating the therapeutic effects. This conceptualization raises a set of important questions regarding neuroscience and translational aspects of fear memory reconsolidation. We discuss the implications of the target article's memory reconsolidation model in the development of more effective interventions, and in the identification of less effective, or potentially harmful approaches, as well as concepts of contextualization, optimal arousal, and combined therapy
Multiple traces or Fuzzy Traces? Converging evidence for applications of modern cognitive theory to psychotherapy
Authors: Reyna Valerie F. , Landa Yulia 
Published: June 2015

AbstractNeurobiologically informed integration of research on memory, emotion, and behavior change in psychotherapy is needed, which Lane at al. advance. Memory reconsolidation that incorporates new emotional experience plays an important role in therapeutic change, converging with evidence for Fuzzy Trace Theory. Applications of Fuzzy Trace Theory to Cognitive Behavioral Therapy (CBT) for youth at risk for psychosis, and to other aspects of behavior change, are discussed.
Conjuring the spirit of multilateralism: Histories of crisis management during the ‘great credit crash’
Authors: SAMMAN AMIN 
Published: June 2015

AbstractIn recent years, critical scholars have emphasised how the recollection of past events as traumas can both constrain and widen the political possibilities of a present. This article builds on such research by suggesting that the management of contemporary financial crises is reliant on a ritual work of repetition, wherein prior ‘crisis’ episodes are called upon to identify and authorise specific sites and modes of crisis management. In order to develop this argument, I focus on how past crises figure within the public pronouncements of four key policymaking organisations during the financial instability of 2007–9. I find that while the Great Depression does enable these organisations to reaffirm old ways of managing crises, both it and the more recent Asian crisis are also made to disclose new truths about the evolution of multilateralism as a form of governance. In so doing, I argue, these historical narratives reveal how the management of global financial crisis depends upon a kind of ‘magic trick’. Rather than a strictly rational, historical process of problem solving, contemporary crises are instead negotiated through a contingent and self-referential conjuring of crisis-histories.
Interaction of an electron beam with whistler waves in magnetoplasmas
Authors: Gupta Ruby , Prakash Ved , Sharma Suresh C. , Vijayshri  
Published: June 2015

AbstractThe present paper studies the whistler wave interaction with an electron beam propagating through magnetized plasma. A dispersion relation of whistler waves has been derived, and first-order perturbation theory has been employed to obtain the growth rate of whistlers in the presence of parallel as well as oblique electron beam. For whistler waves propagating parallel to the magnetic field, that is, parallel whistlers, only the cyclotron resonance appears with a parallel beam, while for whistler waves propagating at an angle to the magnetic field, that is, oblique whistlers interaction with parallel beam or parallel whistlers interaction with oblique beam, the Cerenkov and the cyclotron resonances both appear. The growth rate is found to increase with an increase in the transverse component of beam velocity and with an increase in the strength of magnetic field. The whistler wave frequency decreases with an increase in the beam velocity. The obliqueness of the whistler mode modifies its dispersion characteristics as well as growth rate of the instability. For purely parallel-propagating beams, it is essential for the growth of whistler mode that the wave number perpendicular to the magnetic field should not be zero. The results presented may be applied to explain the mechanisms of the whistler wave excitation in space plasma.
Seed predation in a human-modified tropical landscape
Authors: Zambrano Jenny , Coates Rosamond , Howe Henry F. 
Published: June 2015

Abstract:Contemporary defaunation of fragmented forests potentially alters patterns of seed predation and dispersal. Alternatively, the remaining fauna may compensate for missing animals, resulting in equivalent rates of seed dispersal and predation. In the Los Tuxtlas region of southern Mexico, populations of large terrestrial fruit-eating mammals are diminished or absent from many forest remnants. This study reports fruit removal and seed predation patterns of Poulsenia armata (Moraceae), in forest fragments and a continuous forest (LTBS). Contrary to expectation, we found no differences in seed predation (mean ± SD) between LTBS (7.2 ± 1.8 seeds per station) and forest fragments (5.6 ± 1.1). However more fruits were removed in the LTBS (11.4 ± 0.9 fruits per station) than in forest fragments (8.1 ± 0.8). Animal activity, recorded by camera traps, differed between animal guild with fewer seed dispersers in forest fragments (mean = 0.43 ± 0.02 photos wk−1) than in the LTBS (mean = 0.68 ± 0.05). Fruits and seeds attracted many species of mammal (n = 12) in both habitats, indicating substantial redundancy. Remnant forest patches in the Los Tuxtlas landscape retain great ecological value, both as refuges for mammals and habitats for trees, such as P. armata.
