Spatiotemporal and weather effects on the reproductive success of piping plovers on Prince Edward Island, Canada.

Piping plovers (Charadrius melodus sp.) rank among North America's most endangered shorebird species, facing compounding environmental challenges that reduce habitat availability and suppress recruitment and survival rates. Despite these challenges, research on the direct effects of climate variability and extremes on their breeding ecology remains limited. Here, we employ a spatiotemporal modelling approach to investigate how location, nest timing and weather conditions influence reproductive success rates in a small breeding population of C. m. melodus in Prince Edward Island (PEI), Canada from 2011 to 2023. Analysis of 40 years of monitoring records from a subset of nesting sites revealed that flooding and predation have been persistent sources of reproductive failures in this population, with unexplained losses increasing in recent years. Contrary to our hypotheses, our modelled results did not support a negative impact of extreme high temperatures and strong precipitation events on reproductive outcomes. Instead, we identified a positive effect of T MAX and no effect of strong precipitation, perhaps due to limited exposure to extreme high temperatures (>32°C) and context-specific risks associated with precipitation-induced flooding. However, trends in regional climate change are likely to increase exposure to-and the influence of-such factors in the near future. Our models also identified spatiotemporal variability in apparent hatch success over the study period, as well as worse hatch outcomes across popular beachgoing regions and for delayed nesting attempts. While our results offer preliminary insights into factors affecting breeding success in this population, further research will be imperative to enhance understanding of constraints on recruitment. To this end, we encourage the collection and analysis of additional time-series data of prey populations, human activities, fine-scale weather data and predator/flood risks associated with each nest on PEI.

The effect of terrain on the fine-scale genetic diversity of sub-Antarctic Collembola: A landscape genetics approach.

Biodiversity patterns are shaped by the interplay between geodiversity and organismal characteristics. Superimposing genetic structure onto landscape heterogeneity (i.e., landscape genetics) can help to disentangle their interactions and better understand population dynamics. Previous studies on the sub-Antarctic Prince Edward Islands (located midway between Antarctica and Africa) have highlighted the importance of landscape and climatic barriers in shaping spatial genetic patterns and have drawn attention to the value of these islands as natural laboratories for studying fundamental concepts in biology. Here, we assessed the fine-scale spatial genetic structure of the springtail, Cryptopygus antarcticus travei, which is endemic to Marion Island, in tandem with high-resolution geological data. Using a species-specific suite of microsatellite markers, a fine-scale sampling design incorporating landscape complexity and generalised linear models (GLMs), we examined genetic patterns overlaid onto high-resolution digital surface models and surface geology data across two 1-km sampling transects. The GLMs revealed that genetic patterns across the landscape closely track landscape resistance data in concert with landscape discontinuities and barriers to gene flow identified at a scale of a few metres. These results show that the island's geodiversity plays an important role in shaping biodiversity patterns and intraspecific genetic diversity. This study illustrates that fine-scale genetic patterns in soil arthropods are markedly more structured than anticipated, given that previous studies have reported high levels of genetic diversity and evidence of genetic structing linked to landscape changes for springtail species and considering the homogeneity of the vegetation complexes characteristic of the island at the scale of tens to hundreds of metres. By incorporating fine-scale and high-resolution landscape features into our study, we were able to explain much of the observed spatial genetic patterns. Our study highlights geodiversity as a driver of spatial complexity. More widely, it holds important implications for the conservation and management of the sub-Antarctic islands.

The gendered behaviors displayed by Disney protagonists.

Previous research suggests that the portrayal of male and female protagonists in Disney animations may be changing over time. The current study examined the portrayal of gendered behaviors displayed within some of Disney's most successful animated feature length films, including those beyond the Disney princess franchise. Extending the scope of the Disney animated films analyzed was important because both young girls and young boys report little personal interest in male characters within the Disney princess animations. This suggests that it is important to look beyond the Disney princess franchise to understand the gendered behaviors displayed by potentially influential male Disney protagonists. The current study also considered a greater number of masculine and feminine behaviors as well as some gender-neutral traits which had yet to be incorporated. A quantitative content analysis of 39 Disney protagonists from films released between 1937 and 2021 was conducted. The results revealed that male and female protagonists were statistically higher in feminine than masculine traits. Female protagonists from the earliest animations were the most feminine. However, there was no statistical difference in the gendered portrayals of females in the animations released in the 1990s and those released from 2009 to 2021 suggesting some continued stereotyping in females' profiles. Alternatively, male characters were more feminine relatively consistently across time-points. This study concludes that Disney is persistently portraying stereotyped female protagonists, and this could have implications on young females' behavioral profiles. However, the extent to which feminine traits are being celebrated when displayed by male protagonists needs to be examined, as well as the potential relationship between such messages and boys' behaviors and children's conceptualizations of gender more broadly.

Seasonal Dynamics of Various Scab-Causing Streptomyces Genotypes Among Potato Fields on Prince Edward Island.

Potato common scab is an important bacterial plant disease caused by numerous Streptomyces species and strains. A better understanding of the genetic diversity and population dynamics of these microorganisms in the field is crucial to develop effective control methods. Our research group previously studied the genetic diversity of scab-causing Streptomyces spp. in Prince Edward Island, one of Canada's most important potato-growing provinces. Fourteen distinct Streptomyces genotypes were identified and displayed contrasting aggressiveness toward potato tubers. To better understand the distribution and occurrence of these genotypes over time under field conditions, the population dynamics were studied in nine commercial potato fields throughout a growing season. A comparative genomic-driven approach was used to design genotype-specific primers and probes, allowing us to quantify, using quantitative polymerase chain reaction, the abundance of each of the 14 genotypes in field soil. Thirteen of the previously identified genotypes were detected in at least one soil sample, with various frequencies and population sizes across the different fields under study. Interestingly, weakly virulent genotypes dominated, independent of time or location. Among them, three genotypes accounted for more than 80% of the genotypes' combined population. Although the highly virulent genotypes were detected in lower relative abundance than the weakly virulent ones, an increase in the highly virulent genotypes' population size was observed over the growing season in most fields. The results will ultimately be useful for the development of targeted common scab control strategies.

The Rurikids: The First Experience of Reconstructing the Genetic Portrait of the Ruling Family of Medieval Rus' Based on Paleogenomic Data.

The Rurikids were the reigning house of Rus', its principalities and, ultimately the Tsardom of Russia, for seven centuries: from the IX to the end of the XVI century. According to the Primary Chronicle (the Tale of Bygone Years), the main chronicle of Rus', the Rurik dynasty was founded by the Varangian prince Rurik, invited to reign in Novgorod in 862, but still there is no direct genetic evidence of the origin of the early Rurikids. This research, for the first time, provides a genome-wide paleogenetic analysis of bone remains belonging to one of the Rurikids, Prince Dmitry Alexandrovich (?-1294), the son of the Grand Prince of Vladimir Alexander Yaroslavich Nevsky (1221-1263). It has been established that his Y chromosome belongs to the N1a haplogroup. Most of the modern Rurikids, according to their genealogies, belonging to the N1a haplogroup, have the most similar variants of Y chromosomes to each other, as well as to the Y chromosome of Prince Dmitry Alexandrovich. Genome-wide data of the medieval and modern Rurikids unequivocally indicates that they belong to the N1a haplogroup of the Y chromosome, starting at least from the XI century (since the time of Prince Yaroslav the Wise). All the other alleged Rurikids, both ancient and modern, being carriers of other haplogroups (R1a, I2a), possess high heterogeneity of the sequence of Y chromosomes, meaning that we cannot confirm their common ancestry. The most probable ancestors of Prince Dmitry Alexandrovich in the male line were the men who left the burial ground Bolshoy Oleny Island on the coast of the Kola Peninsula about 3,600 years ago. The reconstruction of the genome of Prince Dmitry Alexandrovich indicates the contribution of three ancestral components to his origin: (1) the early medieval population of the east of Scandinavia from the island of Oland, (2) representatives of the steppe nomadic peoples of the Eurasian steppes of the Iron Age or the early medieval population of central Europe (steppe nomads from the territory of Hungary), and (3) the ancient East-Eurasian component. Reliable statistics were also obtained when the Scandinavians were replaced with the Medieval Russian Slavic populations of the XI century. Thus, for the first time, we have shown the complex nature of interethnic interactions in the formation of the nobility of medieval Rus' on the example of the ancient Rurikid.

Suicide among soldiers and social contagion effects: An interrupted time-series analysis.

BACKGROUND: Suicide has become an increasingly concerning problem among soldiers in recent years. Previous research has hypothesized that media-related social contagion effects, termed "Werther effects," may contribute to military suicide numbers. Unfortunately, there is limited empirical knowledge on such social contagion effects in soldiers. We contribute to the literature by investigating this phenomenon in the context of a specific historical suicide case, allowing us to provide a longitudinal assessment: Crown Prince Rudolf, heir to the Imperial throne of the Austro-Hungarian Empire, who died by suicide in January 1889. His death was a well-known news story that shook the monarchy to its foundations. Notably, soldiers of the late nineteenth century were an especially vulnerable portion of the population, proven by the fact that the Austro-Hungarian military had one of the highest suicide rates at the time compared to other European countries. METHODS AND RESULTS: An interrupted time-series analysis, relying on annual military suicide rates between 1873 and 1910, indicated a significant increase in the suicide rate the year of Rudolf's death, a pattern consistent with a social contagion effect. In fact, time series analysis estimated that there were about 30 excess suicides per 100,000 population within the year of Rudolf's death. Additionally, we identified a substantial change in the trend after Rudolf's death, pointing to a long-term decrease in military suicide rates. The latter was not observed in the general population but appeared to be unique to soldiers. DISCUSSION: Although we are very careful when interpreting causal effects with our historical data, we discuss the latter finding by questioning whether a change in military culture, that is, the establishment of better conditions for soldiers in the aftermath of Rudolf's suicide, contributed to decreasing suicide numbers. Although tentative, these findings are also highly relevant for the study of military suicide today.

Protecting mental health in quarantine: Exploring lived experiences of healthcare in mandatory COVID-19 quarantine, New South Wales, Australia.

Objectives: In response to the COVID-19 pandemic, Australia implemented mandatory hotel quarantine for returned international travellers from March 2020-November 2021. Healthcare was rapidly transformed and scaled up to facilitate delivery of face-to-face and virtual healthcare within quarantine facilities. We sought to understand, from the patient perspective, what a virtual model of healthcare may need to be aware of to respond to, protect, and mitigate people's mental health within a 'public health protection' context of quarantine. Design: Qualitative study design using in-depth semi-structured interviews exploring experiences of the virtual model of healthcare in quarantine. Setting: Special Health Accommodation (SHA) quarantine facilities following Australian Federal and New South Wales (NSW) State quarantine policy, NSW, Australia. Participants: 25 returned international travellers aged 18 years or older of any COVID-19 status who quarantined within SHA between October 2020-March 2021. Results: Participants identified three broad areas of concern. Firstly, their potential to transmit COVID-19, that created anxiety for all participants. Secondly, the effects of losing personal freedoms in quarantine to protect the wider Australian community. Thirdly, many participants entered quarantine during intense biographical moments in their lives, compounding the stress of their experience. Participants felt lost within the 'faceless' quarantine administrative system they navigated prior to their actual arrival in Australia and during their mandated quarantine period. This cumulative experience compromised their expectations and experiences of person-centred care once in quarantine. Conclusions: Quarantine has been a critical public health measure for managing COVID-19 in Australia. The pandemic provides opportunities to learn from quarantine implementation. Participants struggled to separate healthcare provision from the broader quarantine systems and processes. Due to this confusion, blame was directed at healthcare providers for many, and in some cases all difficulties, including those encountered getting into and once within quarantine. Valuable lessons can be learnt from engaging with patients' perspectives to adapt and strengthen future quarantine to deliver responsive, person-centred healthcare.

Paleobiological inferences from paleopathological occurrences in the Arctic ceratopsian Pachyrhinosaurus perotorum.

As a key tool for understanding how animals lived in the past, paleopathology informs us about the lives and deaths of fossil animals. We identify paleopathologies within an assemblage of bones of the pachyrostran centrosaurine Pachyrhinosaurus perotorum, an Arctic ceratopsian. More than 1,000 bones of this dinosaur were collected from the Prince Creek Formation of North Slope, Alaska from fossil sites along the Colville River. Our survey shows the occurrence of paleopathology to be very low and comparable to other populations of horned dinosaurs from the lower latitudes, suggesting that the ancient Arctic environment did not impose intense hardships on these dinosaurs greater than in other environments, as expressed by paleopathological modification of the skeleton. This result may be due to the more equable mean annual temperatures in the Arctic region during the Cretaceous. Also of interest, the frequency of occurrence of paleopathology in the Arctic Pachyrhinosaurus population is very low compared to populations of fossil and historic quadrupedal artiodactyls that are recognized as long distance wanderers.

The life of the prince of anatomists Jean Riolan, Jr. (the Younger) (1577-1657).

For the first time in the history of anatomy, the important French anatomist Jean Riolan, Jr., clarifies several conditions that anatomy adepts should accomplish during their preparation in his work Anthropographia. Anatomists should be physically, mentally, culturally, and ethically ready for their work. The anatomy teacher should consider three rules: have experience in anatomical dissection, have the essential knowledge and approach to dissection, and use a suitable teaching method.

Indigenous Saccharomyces cerevisiae Could Better Adapt to the Physicochemical Conditions and Natural Microbial Ecology of Prince Grape Must Compared with Commercial Saccharomyces cerevisiae FX10.

Indigenous Saccharomyces cerevisiae, as a new and useful tool, can be used in fermentation to enhance the aroma characteristic qualities of the wine-production region. In this study, we used indigenous S. cerevisiae L59 and commercial S. cerevisiae FX10 to ferment Prince (a new hybrid variety from Lion Winery) wine, detected the basic physicochemical parameters and the dynamic changes of fungal communities during fermentation, and analyzed the correlations between fungal communities and volatile compounds. The results showed that the indigenous S. cerevisiae L59 could quickly adapt to the specific physicochemical conditions and microbial ecology of the grape must, showing a strong potential for winemaking. Compared with commercial S. cerevisiae FX10, the wine fermented by indigenous S. cerevisiae L59 contained more glycerol and less organic acids, contributing to a rounder taste. The results of volatile compounds indicated that the indigenous S. cerevisiae L59 had a positive effect on adding rosy, honey, pineapple and other sweet aroma characteristics to the wine. Overall, the study we performed showed that selection of indigenous S. cerevisiae from the wine-producing region as a starter for wine fermentation is conducive to improving the aroma profile of wine and preserving the aroma of the grape variety.

Prince Rupert's Drops: An analysis of fragmentation by thermal stresses and quench granulation of glass and bubbly glass.

When volcanic eruptions involve interaction with external water (hydrovolcanism), the result is an ash-rich and energetic volcanic plume, as illustrated dramatically by the January 2022 Tonga eruption. The origin of the high explosive energy of these events remains an important question. We investigate this question by studying Prince Rupert's Drops (PRDs)-tadpole-shaped glass beads formed by dripping molten glass into water-which have long fascinated materials scientists because the great strength of the head contrasts with the explosivity of the metastable interior when the tail is broken. We show that the fragment size distribution (FSD) produced by explosive fragmentation changes systematically with PRD fragmentation in air, water, and syrup. Most FSDs are fractal over much of the size range, scaling that can be explained by the repeated fracture bifurcation observed in three-dimensional images from microcomputed tomography. The shapes of constituent fragments are determined by their position within the original PRD, with platey fragments formed from the outer (compressive) shell and blocky fragments formed by fractures perpendicular to interior voids. When molten drops fail to form PRDs, the glass disintegrates by quench granulation, a process that produces fractal FSDs but with a larger median size than explosively generated fragments. Critically, adding bubbles to the molten glass prevents PRD formation and promotes quench granulation, suggesting that granulation is modulated by heterogeneous stress fields formed around the bubbles during sudden cooling and contraction. Together, these observations provide insight into glass fragmentation and potentially, processes operating during hydrovolcanism.

Well-Being on Prince Edward Island, Canada: a Statistical Case-Study of Well-Being Related Community Factors.

This research continues the advances in applied positive psychology by measuring and exploring the factors which contribute to the happiness among people living in Prince Edward Island (PEI), Canada. This research provides a province-wide account of subjective well-being (SWB), which is defined as a person's cognitive and affective evaluation of his or her life, by answering the questions: What is the measurable level of well-being of individuals in PEI? What are the relationships between community factors and components of well-being in PEI? Which quality of life factors most influence individual's emotions and life satisfaction in PEI? Participation was voluntary, anonymous, and included just over 1% of the adult population of residents (n = 1381). Data was collected online between October and November 2020. Demographic variables were collected and analyzed using variance of mean scores from three self-reported well-being measures, Satisfaction with Life Scale, Positive and Negative Effect Schedule, and the World Health Organization's (brief) Quality of Life Scale. Regression analysis was used to investigate contributions to well-being. Findings uncovered inequity in well-being among minority populations including, LGBT, gender diverse, Indigenous, disabled, and those living under the poverty line. This study provides a deeper understanding that Islanders view psychological health and healthy environment as important aspects of quality of life influencing their well-being. Results build on existing theories on the influence of income, age, and education have on well-being. Finally, the research provides a starting point and methodology for the continuous measurement and tracking of both the affective and cognitive accounts of well-being on PEI, or in other communities, provinces, or islands. This research provides insight into happiness as an indicator of how our society is performing and adds momentum towards the adoption of sustainable development goals, such as national happiness.

Factors that influence regional resilience planning in Central Karoo, South Africa.

Applied in various disciplines, the concept of resilience has become a catchword in academic and policy discourse across the world. Despite the rapidly growing interest, there is a dearth of literature on resilience in the context of rural areas. To contribute towards extending the existing knowledge, this article analyses factors that influenced the low levels of incorporation of regional resilience in the plans (spatial development frameworks [SDFs]) that guide planning and development in a rural region of Central Karoo, South Africa. The study that the article draws upon revolved around qualitative interviews conducted with seven key informants who were knowledgeable about social, economic and environmental challenges as well as planning and development in the Central Karoo region. The semi-structured interviews were conducted through the online platform of Microsoft Teams. Against the background of low levels of incorporation of regional resilience in the plans that have a bearing on planning and development in the Central Karoo region, it was discovered that the lack of knowledge, financial and human resource constraints and a lack of synergy between different stakeholders were the main reasons for the inadequate incorporation of regional resilience in the subject SDFs. To improve this state of affairs, it is recommended that the stakeholders in the region be empowered on matters pertaining to regional resilience. In terms of empirical research, it is recommended that future studies go beyond the analysis of the content of plans in the manner of this article and analyse the actual regional resilience of rural areas.

Exactitud y precisión de los métodos dentales para estimar la edad basados en la transparencia de la dentina radicular / Accuracy and Precision o Dental Methods to Estimate Age Based Transparenc o Root Dentin / Exatidão e precisão dos métodos odontológicos para estimar a idade com base na transparência da dentina radicular

Introducción: este trabajo buscó determinar la exactitud y precisión de los métodos dentales para estimar la edad, basados en la transparencia de la dentina radicular. Materiales y métodos: estudio transversal de tipo comparativo en el que se evaluaron 90 dientes unirradiculares de una muestra peruana de 90 cadáveres adultos masculinos. En cada diente se midió la altura de la periodontosis, altura radicular y longitud de la transparencia de la dentina radicular. Con estas medidas se hallaron las edades dentales de acuerdo con los métodos de Prince-Ubelaker, Ubelaker-Parra y Vilcapoma, y se compararon los resultados entre sí y con la edad cronológica (edad real). Debido a la normalidad de los datos y a su homocedasticidad, se utilizó la prueba de Pearson, el Anova de un factor para muestras relacionadas y la prueba de Tukey. La exactitud se evaluó mediante las diferencias entre las edades cronológicas y las estimadas por cada método, y la precisión se obtuvo del análisis de confiabilidad y repetibilidad, mediante diagramas de Bland-Altman. El nivel de significancia fue 0.05. Resultados: las exactitudes y precisiones fueron de 0.15-0.14, 2.18-2.07, 3.5-3.11 y 9.92-9.82 para los métodos de Vilcapoma, Ubelaker-Parra, Prince-Ubelaker para masculinos blancos y Prince-Ubelaker para para masculinos negros, respectivamente. Conclusiones: el método de Vilcapoma tuvo mayor exactitud y precisión para estimar la edad.

Objective: To determine the accuracy and precision of dental methods for age estimation based on transparency of root dentin. Materials and Methods: Transversal study of comparative type where 90 uniradicular teeth of a Peruvian sample of 90 male adult corpses were evaluated. In each tooth was mea-sured: height of periodontosis, root height and height of transparency of root dentin. With these mea-surements the dental ages were found according to the methods of Prince-Ubelaker, Ubelaker-Parra and Vilcapoma, comparing the results with each other and with the chronological age (real age). Due to the normality of the data and its homocedasticity, the Pearson test, the one-factor Anova for related samples and the Tukey test were used. Accuracy was evaluated by differences between chronological and esti-mated ages for each method and accuracy was obtained from reliability and repeatability analysis using Bland-Altman diagrams. The significance level was 0.05. Results: Accuracy and precision were 0.15-0.14, 2.18-2.07, 3.5-3.11 and 9.92-9.82 for the Vilcapoma, Ubelaker-Parra, Prince-Ubelaker for white males and Prince-Ubelaker for black males, respectively. Conclusions: The Vilcapoma method had greater accuracy and precision in estimating age.

Conclusões: o método Vilcapoma foi mais preciso e exato na estimativa da idade.

Age-Friendly Cities and Older Indigenous People: An Exploratory Study in Prince George, Canada.

Cities around the world are responding to aging populations and equity concerns for older people by developing age-friendly communities plans, following the World Health Organization's guidelines. Such plans, however, often fail to account for the wide diversity of older people in cities, with the result that some older people, including Indigenous older people, do not see their needs reflected in age-friendly planning and policies. This article reports on a study involving 10 older First Nations and Métis women in the city of Prince George, Canada, comparing the expressed needs of these women with two age-friendly action plans: that of the city of Prince George, and that of the Northern Health Authority. Four main categories were raised in a group discussion and interview with these women at the Prince George Native Friendship Centre: availability of health care services, accessibility and affordability of programs and services, special roles of Indigenous Elders, and experiences of racism and discrimination. There are many areas of synergy between the needs expressed by the women and the two action plans; however, certain key areas are missing from the action plans; in particular, specific strategies for attending to the needs of Indigenous and other older populations who often feel marginalized in health care and in age-friendly planning.

Establishing a robust chimeric antigen receptor T-cell therapy program in Australia: the Royal Prince Alfred Hospital experience.

>himeric antigen receptor (CAR) T-cell therapy is a novel approved cancer treatment that has shown remarkable efficacy in the treatment of patients with relapsed leukemia and lymphoma. Implementation of CAR T-cell therapy in a hospital setting requires careful and detailed planning because of the complexities in delivering this specialist service. A multi-disciplinary approach with dedicated funding is required to meet clinical, scientific, logistic and regulatory requirements. Tisagenlecleucel was the first approved CAR T-cell therapy in Australia. The treatment has been made available to Australian patients in specialist public hospitals through federal and state funding. Royal Prince Alfred Hospital (RPAH) is one of Australia's oldest tertiary referral public health care institutions and was approved for the provision of CAR T-cell therapy service in 2019. A multi-disciplinary clinical program has been established for the collection and cryopreservation of donor cells shipped for manufacturing as well as for the receipt, storage and administration of CAR T-cell therapy and patient management. The program encompasses a Therapeutic Goods Administration-accredited apheresis unit and a state-of-the-art facility for cell processing, cryopreservation and storage. The program's clinical expertise extends to hematology, oncology, intensive care, pharmacy, neurology and radiology services with direct experience in managing patients receiving CAR T-cell therapies. The introduction of CAR T-cell therapies at RPAH was a complex undertaking facilitated by the existing infrastructure and clinical expertise.

The Coleoptera of the Province of Prince Edward Island, Canada: 295 new records from Lindgren funnel traps and a checklist to species.

The Coleoptera fauna of the province of Prince Edward Island has long been one of the most poorly known jurisdictions in Canada, with fewer than half the number of species recorded in the neighbouring provinces of New Brunswick and Nova Scotia. If much of the difference in species richness was due to less intensive sampling of the province compared to other parts of Atlantic Canada it was predicted that surveys with semiochemical-baited traps would detect many previously undetected species. Lindgren funnel traps were baited with longhorn beetle pheromones and host volatiles and placed in the canopy and understory of coniferous and deciduous trees at the Valleyfield, New Harmony, Auburn, and Brookvale Demonstration Woodlots during the summers of 2018 and 2019. Two hundred and ninety-five species of Coleoptera are newly recorded from Prince Edward Island from 53 families. One of these, the Palaearctic Pityophagusferrugineus (Linnaeus, 1760) is reported for the first time from North America and Canada. The families Lycidae, Derodontidae, Lymexylidae, Sphindidae, Cucujidae, Ripiphoridae, Salpingidae, and Nemonychidae are newly recorded for the province. A checklist of the Coleoptera of Prince Edward Island is provided.

Effect of Cultivar, Plant Spacing and Harvesting Age on Yield, Characteristics, Chemical Composition, and Anthocyanin Composition of Purple Napier Grass.

Purple Napier grass is a semi-dwarf, purple-leaved Napier grass. The purple color is anthocyanins. Anthocyanin is classified as a group of flavonoids. It has antioxidant properties. The objective of this study was to determine the effect of plant spacing and harvesting age on the forage yield, morphological characteristics, chemical composition, and anthocyanin composition of purple Napier grass. An experiment was conducted to determine the effect of plant spacing and harvesting age on the forage yield, morphological characteristics, chemical composition, and anthocyanin composition of purple Napier grass when grown on a sandy soil. The cultivars were Napier Pakchong 1 (Pennisetum purpureum × Pennisetum americanum cv. Pakchong 1) and purple Napier grass (Pennisetum purpureum "Prince"), with plant spacings of 50 × 50, 50 × 75, and 75 × 75 cm, and the harvesting ages were 45, 60, and 75 days. The experiment was a 2 × 3 × 3 factorial layout in a randomized complete block design with four replications, for a total of 72 plots, each 5 × 5 m. The purple Napier grass had a higher number of tillers per plant than the Napier Pakchong 1 grass. The LSR value (leaf/stem ratio) was influenced by the interaction of cultivar × plant spacing × harvesting age. The purple Napier grass planted at 75 × 75 cm for 45 days had the highest LSR value. The crude protein of the purple Napier grass, the grass planted at 75 × 75 cm, and the grass for 45 days were significantly higher than the other treatments. The purple Napier grass planted at 75 × 75 cm for 45 days had the highest (p < 0.05) anthocyanin content. It was concluded that purple Napier grass planted at 75 × 75 cm for 45 days would contain the proper number of tillers per plant, LSR value, chemical composition for ruminants, and the highest anthocyanin composition.

Unbreakable Resolutions as an Effective Tactic for Self-Control: Lessons From Mahatma Gandhi and a 19th-Century Prussian Prince.

Despite the relative consensus in the self-management literature that personal resolutions are not an effective stand-alone tactic for self-control, some individuals seem capable of using them to exert a remarkable level of control over their behavior. One such individual was Mahatma Gandhi, the famous Indian statesman. Gandhi often used personal resolutions-or "vows"-to commit himself to a range of challenging behaviors, such as extreme diets, sexual abstinence, and fasting. Similarly, Prince Pückler-Muskau, a celebrated 19th-Century adventurer, landscape designer and travel author, described using personal resolutions to unfailingly accomplish numerous tasks in his everyday life. In this article, we examine the historical writings of Gandhi and Pückler-Muskau concerning their use of resolutions. We describe three defining characteristics of their resolutions, which we will refer to as unbreakable resolutions, and outline Gandhi's advice for making and keeping such resolutions. Our analysis suggests that the effectiveness of unbreakable resolutions may be primarily due to the temporally extended contingencies of reinforcement associated with their use, and can be usefully interpreted from the perspective of delay-discounting and say-do correspondence models of self-control. The implications of this examination for understanding the concept of willpower and for enhancing modern research into self-control training are also discussed. Based on this analysis, we additionally offer a tentative set of guidelines on how to make and keep unbreakable resolutions.

Nasopharyngeal Carriage of Streptococcus pneumoniae Among Young Children in Haiti Before Pneumococcal Conjugate Vaccine Introduction.

BACKGROUND: Streptococcus pneumoniae, or pneumococcus, is a leading cause of morbidity and mortality in children worldwide. Pneumococcal conjugate vaccines (PCV) reduce carriage in the nasopharynx, preventing disease. We conducted a pneumococcal carriage study to estimate the prevalence of pneumococcal colonization, identify risk factors for colonization, and describe antimicrobial susceptibility patterns among pneumococci colonizing young children in Port-au-Prince, Haiti, before introduction of 13-valent PCV (PCV13). METHODS: We conducted a cross-sectional study of children aged 6-24 months at an immunization clinic in Port-au-Prince between September 2015 and January 2016. Consenting parents were interviewed about factors associated with pneumococcal carriage; nasopharyngeal swabs were collected from each child and cultured for pneumococcus after broth enrichment. Pneumococcal isolates were serotyped and underwent antimicrobial susceptibility testing. We compared frequency of demographic, clinical, and environmental factors among pneumococcus-colonized children (carriers) to those who were not colonized (noncarriers) using unadjusted bivariate analysis and multivariate logistic regression. RESULTS: Pneumococcus was isolated from 308 of the 685 (45.0%) children enrolled. Overall, 157 isolates (50.8%) were PCV13 vaccine-type serotypes; most common were 6A (13.3%), 19F (12.6%), 6B (9.7%), and 23F (6.1%). Vaccine-type isolates were significantly more likely to be nonsusceptible to ≥1 antimicrobial (63.1% vs 45.4%, P = .002). On bivariate analysis, carriers were significantly more likely than noncarriers to live in a household without electricity or running water, to share a bedroom with ≥3 people, to have a mother or father who did not complete secondary education, and to have respiratory symptoms in the 24 hours before enrollment (P < .05 for all comparisons). On multivariable analysis, completion of the pentavalent vaccination series (targeting diphtheria, pertussis, tetanus, hepatitis B, and Haemophilus influenzae type b) remained significantly more common among noncarriers. CONCLUSIONS: Nearly a quarter of healthy children surveyed in Haiti were colonized with vaccine-type pneumococcal serotypes. This baseline carriage study will enable estimation of vaccine impact following nationwide introduction of PCV13.
