Published: May 2019

ABSTRACTThe goal of this study was to evaluate factors causing low recovery of Campylobacter during regulatory sampling following acidified sodium chlorite (ASC) treatment of broiler carcasses and subsequent carry‐over into neutralizing buffered peptone water (nBPW) rinses. Solution alkalinity was shown to positively correlate with the presence of un‐reduced chlorite anion in the recovery broth, implying that low recovery of Campylobacter from rinses may be due to residual chlorite, an oxidizing agent. To demonstrate the susceptibility of Campylobacter to residual chlorite, three strains were inoculated into pH = 7.5 nBPW with or without addition of sodium chlorite and stored for 24 hr at 4 °C prior to culturing. Microbial counts from the solutions indicated that residual chlorite can decrease recovery by up to 4 log CFU/mL relative to controls. Acceptable recovery of Campylobacter from nBPW rinses containing residual chlorite may require development of a suitable neutralizing agent in the nBPW recovery medium.Practical applicationsRecovery of viable Campylobacter spp. from broiler carcasses following antimicrobial treatment with acidified sodium chlorite may potentially be compromised when using nBPW as the recovery medium. At neutral or slightly alkaline pH, residual sodium chlorite, an oxidizing species, is not reduced by thiosulfate present in nBPW, and demonstrates antimicrobial effects on Campylobacter. Development of a suitable alternative to thiosulfate as a reducing agent in the recovery medium may be required in to provide optimal conditions for recovery of Campylobacter.
On the Effectiveness of Loan‐to‐Value Regulation in a Multiconstraint Framework
Authors: GRODECKA ANNA 
Published: May 2019

AbstractModels in the infinite horizon macro‐housing literature often assume that borrowers are constrained exclusively by the loan‐to‐value (LTV) ratio. Motivated by the Swedish microdata, I explore an alternative arrangement where borrowers are constrained by a collateral constraint and by a debt‐service‐to‐income ratio. While stricter LTV limits are often considered as a measure to tackle the rise in household indebtedness, I find that policy designed to lower the maximum permissible LTV ratio may actually leave the debt‐to‐GDP ratio unchanged and increase housing prices in equilibrium if borrowers are bound by two constraints at the same time.
Do Stronger Patents Stimulate or Stifle Innovation? The Crucial Role of Financial Development

AbstractThis study explores the effects of patent protection in a research and development (R&D)‐based growth model with financial frictions. We find that whether stronger patent protection stimulates or stifles innovation depends on credit constraints faced by R&D entrepreneurs. When credit constraints are nonbinding (binding), strengthening patent protection stimulates (stifles) R&D. The overall effect of patent protection on innovation follows an inverted‐U pattern. By relaxing the credit constraints, financial development stimulates innovation. Furthermore, patent protection is more likely to have a positive effect on innovation under a higher level of financial development. We consider cross‐country panel regressions and find supportive evidence for this result.

AbstractThe skin surface structure of squamate reptiles varies greatly among species, likely because it plays a key role in a range of tasks, such as camouflage, locomotion, self‐cleaning, mitigation of water loss and protection from physical damage. Although we have foundational knowledge about squamate skin morphology, we still know remarkably little about how intraspecific variation in skin surface structure translates to functional variation. This gap in our understanding can be in part traced back to: (i) our lack of knowledge on how body size determines skin surface structure; and (ii) the lack of means to perform high‐throughput and detailed analysis of the three‐dimensional (3D) anatomy of reptilian skin surfaces in a non‐destructive manner. To fill this gap, we explored the possibilities of a new imaging technique, termed gel‐based stereo‐profilometry, to visualize and quantify the 3D topography of reptilian skin surface structure. Using this novel approach, we investigated intra‐specific and intra‐individual variation in the skin surface morphology of a focal lizard species, Anolis cristatellus. We assessed how various characteristics of surface topography (roughness, skew and kurtosis) and scale morphology (area, height, width and shape) scale with body size across different body regions. Based on an ontogenetic series of A. cristatellus males, we show that skin roughness increases with body size. Skin patches on the ventral body region of lizards were rougher than on the dorsum, but this was a consequence of ventral scales being larger than dorsal scales. Dorsal surface skew and kurtosis varied with body size, but surfaces on the ventral skin showed no such relationship. Scale size scaled isometrically with body size, and while ventral scales differed in shape from dorsal scales, scale shape did not change with ontogeny. Overall, this study demonstrates that gel‐based stereo‐profilometry is a promising method to rapidly assess the 3D surface structure of reptilian skin at the microscopic level. Additionally, our findings of the explanatory power of body size on skin surface diversity provide a foundation for future studies to disentangle the relationships among morphological, functional and ecological diversity in squamate reptile skin surfaces.

Published: May 2019

In the current study, we strategically link the work–family literature to employee creativity, a construct seen as a linchpin for organizational success, through family‐supportive supervision based on the concept of reciprocity of interdependent exchanges within social exchange theory. In Study 1 (N = 188), based on data with a one‐month lag between two assessments, we demonstrate that family‐supportive supervision is an explanatory leadership behaviour that connects broader leadership styles (i.e., leader–member exchange) to employee creativity. In Study 2, we further unpack the theoretical exchange processes at work to better address the leadership–creativity black box. With a sample of 251 participants, surveyed at two time points, we leverage a motivational process model and demonstrate that meaningfulness and intrinsic motivation mediate the relationship between family‐supportive supervision and creativity. These findings provide insight into the motivational mechanisms involved in the social exchange process and implications for inciting employee creativity through family‐supportive supervision.Practitioner points

We demonstrate that family‐supportive supervision is an important driver of constructs of strategic importance (e.g., motivation, creativity) to many organizations.

We provide practitioners with a focused opportunity for intervention to promote creativity given that leaders can be trained to engage in family‐supportive behaviours.

We provide evidence that should encourage practitioners to start thinking about processes related to sustaining creativity.
A Meta‐Analysis of Friendship Qualities and Romantic Relationship Outcomes in Adolescence
Authors: Kochendorfer Logan B. , Kerns Kathryn A. 
Published: May 2019

Romantic relationships are one of the most significant interpersonal ties in adolescence, thus understanding factors that may contribute to their formation and quality are important. The current meta‐analysis focuses on links between friendship quality and romantic relationship outcomes for adolescents up to 18 years. In a series of meta‐analyses (k = 28 studies, N's = 946–4,040), friendship qualities were not related to romantic involvement. However, we did find robust evidence of continuity between friendship qualities and romantic relationship qualities. Additionally, adolescents experienced more negative quality in their romantic relationships than in their friendships. These findings suggest that friendships have implications for adolescents’ romantic relationships, although more research is needed on specific quality associations, and the mediators of these relations.
The Mediating Role of Multiple Group Identities in the Relations between Religious Discrimination and Muslim‐American Adolescents’ Adjustment

AbstractDespite increasing anti‐Muslim sentiments, the implications of religious discrimination for Muslim‐American adolescents’ well‐being remain understudied. Drawing on the rejection identification and disidentification models, we examined the mediating role of multiple group identities (i.e., religious and national) in the cross‐sectional associations between individual‐level religious discrimination and internalizing and externalizing problems among 13‐ to 18‐year‐old (M = 16.7 years, SD = 1.6) Muslim‐American adolescents with immigrant backgrounds. Moreover, building on the attributional ambiguity perspective, we examined the moderating role of group‐level religious discrimination in the form of Islamophobia. Religious identity did not mediate the relations between individual‐level discrimination and internalizing and externalizing problems, and these relations did not depend on youths’ perceptions of Islamophobia. However, individual‐level discrimination was associated with American identity, depending on perceptions of Islamophobia. In turn, adolescents’ Muslim and American identities were linked to less internalizing and externalizing problems. Implications of our findings for the development of programs and policies are discussed.

AbstractThe familial placements of Cyrtandromoea Zoll. and Wightia Wall., two small and enigmatic South‐East Asian genera, have long been controversial in Lamiales. Here we adopt a two‐step approach to resolve their phylogenetic relationships. We initially reconstructed a large‐scale phylogeny of Lamiales using six chloroplast markers (atpB, matK, ndhF, psbBTNH, rbcL, and rps4). The results showed that both Cyrtandromoea and Wightia emerged in the LMPO clade, including Lamiaceae, Mazaceae, Phrymaceae, Paulowniaceae, and Orobanchaceae. Based on the second set of six chloroplast markers (atpB, matK, ndhF, rbcL, rps16, and trnL‐F) and two nuclear ribosomal regions (external transcribed spacer and internal transcribed spacer) for the analyses focusing on the LMPO clade, our results revealed that Cyrtandromoea was consistently nested within Phrymaceae, whereas Wightia was supported as sister to Phrymaceae by the chloroplast DNA dataset or sister to Paulowniaceae by the nuclear ribosomal DNA dataset. Morphological and anatomical evidence fully supports the inclusion of Cyrtandromoea in Phrymaceae, and an updated tribal classification is done for Phrymaceae with five tribes, that is, Cyrtandromoeeae Bo Li, Bing Liu, Su Liu & Y. H. Tan, trib. nov., Diplaceae Bo Li, Bing Liu, Su Liu & Y. H. Tan, trib. nov., Leucocarpeae, Mimuleae, and Phrymeae. The conflicting phylogenetic position of Wightia indicated by different genome markers results in difficulty placing the genus in either Phrymaceae or Paulowniaceae. Considering the distinct morphological differences between Wightia and other families in the LMPO clade, we here propose a new family, Wightiaceae Bo Li, Bing Liu, Su Liu & Y. H. Tan, fam. nov., to accommodate it, which is the 26th family recognized in Lamiales.

Published: May 2019

AbstractBackgroundHypokalemia is of clinical relevance in cattle. Different mostly empirical treatment options are suggested.Hypothesis/ObjectivesTo evaluate if oral administration of potassium influences the plasma concentration, the intracellular concentration in erythrocytes and in muscle, renal excretion of potassium, and to assess if there are differences in the efficacy of the potassium formulations.AnimalsThirty cows with hypokalemia (plasma concentration <3.5 mmol/L) were systematically allocated to 3 treatment groups (10 cows/group).MethodsThe cows received 52 g of potassium in different formulations: group B—potassium chloride bolus (release over 12 hours); group G—potassium propionate gel (release over 2 hours); and group S—potassium chloride solution (immediately available). Potassium concentrations were repeatedly measured in plasma, erythrocytes, muscle, and urine using ICP‐OES.ResultsPlasma potassium concentrations for all preparations increased within 30 minutes and the increase lasted for 12 hours. The concentrations of potassium in the erythrocytes and in the muscle, renal potassium excretion, and total urine volume were not affected by administration of any product. There were no differences between the treatments groups. The feed intake increased in 50% of cows within 2 hours after potassium application, which may contribute to the increase of plasma potassium concentration.Conclusions and Clinical ImportanceAll the studied potassium formulations are equally effective to treat hypokalemia in dairy cows for over 12 hours but do not influence intracellular concentration or renal excretion of potassium. The plasma potassium concentration should be reevaluated after 12 hours.

AbstractDonor human milk (DHM) is recomended as the best alternative when use of mothers' own milk is not a feasible option. Kenya has not yet established human milk banks (HMBs) for provision of safe DHM, which is free from any physical, chemical, microbiological contaminants or pathogens. This study aimed to establish the perceptions on donating and using DHM, and establishing HMBs in Kenya. Qualitative data were collected through 17 focus group discussions, 29 key informant interviews, and 25 in‐depth interviews, with women of childbearing age, community members, health workers, and policy makers. Quantitative interviews were conducted with 868 mothers of children younger than 3 years. Descriptive analysis of quantitative data was performed in STATA software, whereas qualitative interviews were coded using NVIVO and analysed thematically. Majority of them had a positive attitude towards donating breast milk to a HMB (80%) and feeding children on DHM (87%). At a personal level, participants were more willing to donate their milk to HMBs (78%) than using DHM for their own children (59%). The main concerns on donation and use of DHM were personal dislikes, fear of transmission of diseases including HIV, and hygiene concerns. Ensuring safety of DHM was considered important in enhancing acceptability of DHM and successful establishment of the HMBs. When establishing HMBs, Kenya must take into consideration communication strategies to address the main concerns raised regarding the quality and safety of the DHM. The findings will contribute to the development of HMB guidelines in Kenya and other African contexts.

AbstractSouthern right whales (SRW), Eubalaena australis, have reoccupied historically important winter habitat ranges (calving grounds) in recent years along the southern Australian coast. Here we present findings of increased abundance of SRW at Fowlers Bay, South Australia, a previous shore‐based whaling station. This study investigates: SRW inter‐ and intraseasonal trends in relative abundance; changes to the relative proportion of the southwestern subpopulation represented by SRW at Fowlers Bay; distribution; and occupancy. Sighting and photo identification data were collected during annual aerial (1993–2016) and vessel surveys (2014–2016). The total number of female and calf pairs was 3 during 1993–2003 and 63 during 2004–2014. Despite high variability in annual relative abundance, the rate of mean increase from 1993 to 2016 (29.0%/yr, 95% CI = 0, 54.2) exceeded the maximum biological rate for the species (6%–7%/yr). Peak relative abundance was recorded in July and August. SRW at Fowlers Bay represent an increasing proportion of the southwestern subpopulation (range = 0.9%–7.4%). Mean occupancy was 23 d (range = 1–75) for female and calf pairs and 2 d (range = 1–15) for unaccompanied adults. Reduced sightings in 2015 and 2016 demonstrate plasticity in SRW abundance at Fowlers Bay. Research into the movement and connectivity of SRW is needed to understand drivers of habitat dispersal in Australia.
Bloodmeal analysis in Culicoides midges collected near horses, donkeys and zebras in the Eastern Cape, South Africa

AbstractAn upsurge in African horse sickness (AHS) in the Eastern Cape, South Africa, from 2006 led to an epidemiological reassessment of the disease there. Light trapping surveys carried out near horses, donkeys and zebras in 2014–2016 collected 39 species of Culicoides midge (Diptera: Ceratopogonidae) that are potential vectors of AHS. To establish if these midges fed on equids, DNA sequences were obtained from the gut contents of 52 female midges (35 freshly blood‐fed, 13 gravid and four parous), representing 11 species collected across 11 sites. Culicoides leucostictus fed on all three equids. Culicoides bolitinos, Culicoides imicola and Culicoides magnus fed on both horses and donkeys. Culicoides onderstepoortensis fed on donkeys, and Culicoides similis and Culicoides pycnostictus fed on zebras. Bloodmeals from cows, pigs, warthogs, impalas and a domestic dog were also identified in various species, but none of the midges tested had fed on birds. These results contribute to knowledge of the vectorial capacity of several species of Culicoides with regard to AHS in the Eastern Cape and point to potential reservoir hosts, of which donkeys, zebras and domestic dogs have previously been found to harbour AHS. Blood‐fed midges were also obtained throughout winter, indicating the potential for endemic AHS in the province.

Published: May 2019

ABSTRACTAimKidney disease of unknown aetiology (CKDu) has been a health problem in the rural farming community of the North Central province of Sri Lanka since the 1990s and various environmental factors have been postulated as contributing factors for this disease. The aim of our study was to find out whether farmers undergo dehydration which would lead to concentration of urine and the water soluble potentially toxic substance in the kidney, leading to damage of the renal tubules. Therefore, we studied a sample of healthy farmers who were CKDu‐free to determine whether they were dehydrated.MethodsSample included healthy male paddy farmers of Padaviya in the Anuradhapura district. Plasma and urine osmolarity were recorded upon waking up in the morning and evening during the non‐farming and farming seasons. Basic statistics and a 2 × 2 anova was done to test the interaction of time of day with farming activity.ResultsFarmers were dehydrated according to the plasma osmolarity especially in the mornings, irrespective of whether they were farming or not. Approximately 40% of the sample also demonstrated acute dehydration at the end of the day due to farming activity as indicated by both plasma and urine osmolarity and specific gravity.ConclusionThis study revealed that the farmers of the Padaviya area were either dehydrated or at the upper limit of euhydration sometime during the day irrespective of their activities during the day.

AbstractAims and objectivesThe aims were to (a) identify how many older people with cognitive impairments are living in modified homes and (b) explore associated factors, and (c) examine the mediating effects that their caregivers’ information needs and perceptions of fall risk and other factors.BackgroundOlder people and their informal caregivers may consider implementing home modifications as an effective strategy for fall prevention. However, there is a lack of information on which older people's homes receive modifications and the various factors associated with such modifications among community‐dwelling older people with cognitive impairments.DesignThis cross‐sectional and correlational study utilises a secondary data analysis.MethodsThe data for this secondary analysis were taken from the 2015 National Online Survey of Caregivers, which includes information provided by 226 adult caregivers for older people with cognitive impairments. Descriptive analyses, hierarchical binary logistic regression and structural equation modelling were performed based on the Andersen and Newman framework of health services utilisation.ResultsOverall, 46.5% of the older people lived in modified homes. Older people's impaired activities for daily living (ADLs), caregivers’ information needs and perceptions of fall risk were all associated with home modifications (all p values<0.05). Caregivers’ information needs mediated the relationship between impaired ADLs and home modifications (indirect effect = 0.026, p < 0.05), whereas the caregivers’ perceptions of fall risk did not.ConclusionsOlder people with both cognitive and functional impairments are more likely to modify their home on behalf of care recipient's staying at home. Caregivers’ information needs should thus be prioritized when considering home modifications to facilitate caring for older people with impaired ADLs.Implication for practiceNurses and other healthcare professionals should be prepared to offer appropriate information and comprehensive assessments of older people's conditions with regard to home modifications.
