Authors: Loría Valverde Jose Loría Valverde , Noguera Bonilla Priscilla Noguera Bonilla , Calderón Ramírez Guillermo
Published: July 2022

La brecha espacial respecto a la cobertura total de los servicios en salud sigue distanciada de los umbrales ideales de accesibilidad y disponibilidad. Esto está relacionado con la inequidad espacial, que no deja de ser una desigualdad evitable y no justificable. Este artículo tiene como objetivo identificar la accesibilidad espacial de la población de ocho sectores de salud a la nueva Sede de Área de Salud Guápiles (SASG) de Costa Rica, en el año 2020, a partir del análisis espacial de criterios geográficos divididos en distancia y tiempo recorridos respecto a la sede, y la influencia del crecimiento de la mancha urbana en el área de estudio. Los resultados muestran que, solo cuatro de ocho sectores en estudio presentan en promedio más del 60% de su población dentro de la cobertura media o ideal de accesibilidad de acuerdo con los indicadores propuestos, mientras que, la expansión urbana tiene una alta probabilidad de mantenerse o incluso crecer en el área de estudio. Se concluye que, incluir criterios geográficos como los analizados brindan oportunidades y herramientas para la planificación de los servicios de salud en Costa Rica, específicamente, en la toma decisiones ajustadas a la realidad, equidad y dinámica socio espacial de las Áreas de Salud.

Published: July 2022

A Geografia e a Religião têm uma relação intemporal. Enquanto o estudo das religiões tem suscitado a atenção de grande círculo de investigadores das áreas da Sociologia, Antropologia, Filosofia, História, em especial a Teologia, a Geografia tem permanecido mais discreta. Todavia, tendo em conta esta diversidade de interesses e perspetivas, concebemos a pergunta de partida deste artigo: que contribuições tem dado Geografia no domínio da Religião? A partir de uma abordagem em forma de ensaio reflexivo, o objetivo deste trabalho é o de sistematizar analiticamente a produção bibliográfica de cariz geográfico do mundo anglófono, em especial para as fontes bibliográficas primárias produzidas durante o séc. XX, com foco nas décadas de 60, 70 e 80.

Introducción y objetivo: el vértigo es un síntoma frecuente en la población adulta, pero mucho menos habitual en niños y adolescentes. Mientras que la etiología del vértigo se ha establecido con suficiente evidencia científica en adultos, el diagnóstico en la edad pediátrica no se ha descrito con la misma fuerza por una menor casuística. Los objetivos de este artículo son evaluar la prevalencia y características clínicas de los trastornos vestibulares en niños y adolescentes y realizar una revisión bibliográfica de los últimos estudios epidemiológicos al respecto. Método: nuestro estudio es observacional, retrospectivo, no aleatorizado y realizado en el servicio de Otorrinolaringología del Hospital General Universitario de Castellón. Incluimos 20 pacientes con edades comprendidas entre 18 meses y 20 años, que consultaron por alteraciones en el equilibrio a lo largo de 2 años (2017-2018). Resultados: la migraña vestibular (45%) fue el cuadro más frecuente en nuestra serie, seguido del vértigo paroxístico benigno de la infancia (30%). La enfermedad de Ménière, la neuritis vestibular o la paroxismia vestibular, fueron cuadros menos frecuentes. Conclusiones: el vértigo en niños y adolescentes es una queja relativamente común, pese a estar subestimado en la práctica clínica. Se trata de una patología de bastante importancia puesto que supone un problema que puede influir en el aprendizaje, concentración e, incluso, en la capacidad lectora. Aunque las causas más frecuentes de vértigo en la edad pediátrica son la migraña vestibular y el vértigo paroxístico de la infancia, las etiologías son muy numerosas. Por otro lado, la historia clínica y la exploración otoneurológica son esenciales en el diagnóstico de trastornos vestibulares infantiles. Y, por último, las pruebas de imagen son necesarios en aquellos pacientes sugestivos de centralidad al presentar clínica neurológica, cefaleas persistentes, o traumatismo craneoencefálico previo.

Authors: Carol Pinheiro  , Sulekha Rani Rugmini  , Alagurajan Krishnaveni  , Lakshmi Rajeev Thuruthiyath
Published: July 2022

BACKGROUND

The rapid physical growth and development in adolescence are associated with increased nutritional needs and this depends on the dietary pattern and eating habits of the adolescents. Adolescence is also a period of increased vulnerability to obesity which is not only linked to food intake but also due to a lack of physical activity in the growing years. Dietary habits that are established during adolescence are often sustained till adulthood. Hence the purpose of the study was to understand the prevalence of unhealthy dietary practices among adolescents that could enable schools to create a health-promoting culture by teaching healthy food choices and creating awareness of the ill effects of unhealthy dietary practices.

METHODS

A cross-sectional study was conducted using a semi-structured questionnaire among adolescents in the age group 15 to 17 years in a panchayat in Kerala. The socio-demographic characteristics, the family details and dietary practices were recorded, height and weight were measured, and BMI was calculated and ELIZ health pathway for adolescents (EPHA) was used for categorising the study participants. A diet score was also calculated to estimate the prevalence of unhealthy dietary practices among adolescents.

RESULTS

The prevalence of inadequate consumption of fruits was 60.9 % and inadequate consumption of vegetables was 36.9 %. Based on the dietary score, 36.7 % had poor dietary habits and 36.6 % had good dietary habits. A significant association was found between the type of school, occupation of mother, educational status of parents, type of family and inadequate consumption of fruits and vegetables.

CONCLUSIONS

An unhealthy lifestyle does not just appear in adulthood, it stems from practices children develop during their childhood and adolescence. Awareness regarding the risk factors of non-communicable diseases should be provided to children to enable primordial and primary prevention as powerful tools to prevent these diseases in future.

Introducción: El bienestar es un constructo importante cuyos determinantes asociados deben ser identificados para comprender con mayor profundidad los procesos para envejecer de forma saludable. El estudio del impacto de la fragilidad en el bienestar de las personas mayores requiere incorporar los dominios físico, psicológico y social. Así, el adulto mayor frágil puede definirse a partir de la fragilidad física, junto con la soledad como fragilidad social. Este estudio propone un modelo para estudiar el impacto de la fragilidad física y la soledad sobre el bienestar de las personas mayores, diferenciando entre control, autonomía, placer y autorrealización. Métodos: Se realizó un estudio de carácter transversal con una muestra de 13569 personas mayores provenientes de la encuesta SHARE, para estimar un modelo de ecuaciones estructurales en el que se contemplaban los efectos de la fragilidad y la soledad en el bienestar (cuestionario CASP), controlado por el género, la edad y la salud percibida. Resultados: El modelo final contemplaba el efecto del género sobre el indicador de fuerza de prensión de fragilidad. Los resultados mostraron un ajuste adecuado del modelo a los datos y consiguieron explicar un 80.1% de la varianza de control, un 48.6% de la de autonomía, un 43.6% de la de placer y un 61.3% de la varianza de autorrealización. Conclusiones: La soledad y la fragilidad presentaron efectos diferenciales en función del componente de bienestar. Se discuten las implicaciones de dichos efectos en el desarrollo de intervenciones.

Authors: Iswantoro Adhi , Ariana I Made , Syuhri Muhammad
Published: July 2022

Now the demand for fuel oil has increased, this can cause fuel oil reserves to be depleted. To reduce the use of fuel oil, alternative energy is needed. One alternative energy that can be used to reduce fuel oil consumption is LPG (Liquid Petroleum Gas). The use of alternative fuels for LPG in diesel engines is done by converting diesel engines into dual fuel. This research aims to determine the effect of using dual fuel that are LPG-Diesel fuel on engine performance including power, torque, fuel consumption, emissions, vibration and noise. The research was conducted using a Yanmar TF 85 MH engine at 2000 RPM engine speed with variations in loading of 1000, 1500, 2000, 2500, and 3000 watts, and dual fuel with variations in injector openings of 3ms, 4ms, 5ms. Based on the research results, the use of LPG in dual fuel system with installing ECU (Electronic Control Unit) converter-kit, can replace diesel fuel oil consumption up to 93%. In the use of dual fuel there is an average decrease in power and torque of up to 1.95% if using only diesel fuel have average power up to 2.32 kW and torque up to 11.09 Nm. When using dual fuel there is a decrease in specific fuel oil consumption by up to 44% when using only diesel fuel have average fuel oil consumption up to 414.15 g/kWh. The maximum NOx emission produced is 1.83 g/kWh for a 3ms gas injector opening, 1.48 g/kWh for a 4ms gas injector opening, and 1.81 g/kWh for a 5ms injector opening. The maximum vibration generated is 33.2 m/s² for a 3ms injector opening, 31.4 m/s² for a 4ms injector opening, 27.46 m/s² for a 5ms injector opening, and when used only Diesel Fuel is 32.8 m/s2. The maximum noise generated is 92.33 dBA for 3ms injector opening, 92.43 dBA for 4ms injector aperture, 93.20 dBa for 5ms injector aperture, and 91.73 dBa when using diesel oil only.

Framing pension reform in the news: Traditional versus social media
Authors: Heijkant Linda van den , Selm Martine van , Hellsten Iina , Vliegenthart Rens
Published: July 2022

Social media are increasingly important in the news menu of media users. Differences in news production processes between traditional and social media may lead to differences in how political and social issues are depicted, and this may, eventually, have consequences for the information that reaches citizens about an issue. Against this background, this study compares content across the two media types to examine whether and how the framing of a sociopolitical issue differs between newspaper articles and posts on social media. The empirical analyses are based on a content analysis of newspaper articles (n = 414) and social media messages (n = 2,771) conducted in the context of the socially contested issue of raising the retirement age in the Netherlands. Findings suggest that different content production processes can still lead to similar outcomes as both media types emphasize problems with (instead of solutions to) the retirement age issue. Our findings also confirm differences across traditional and social media, although these differences are substantially relatively small. While traditional news media emphasize conflict-related frames more often than social media, social media present more frame diversity in solutions.

Success Factors in Equity Crowdfunding – Evidence from Crowdcube
Authors: Du Lisha , Bartholomae Florian , Stumpfegger Eva
Published: July 2022

Equity crowdfunding has been gaining more and more relevance as an alternative way for entrepreneurs to raise capital. This paper examines the impact of retained equity, business angel backing, grants and intellectual property rights on the success of equity crowdfunding. Using data from Crowdcube, one of the leading equity crowdfunding platforms in the world, we obtain 473 pitches within the period from March 2017 to February 2020. We apply three empirical methods to analyse our data set: logistic regression, multiple linear regression and negative binomial regression. By running univariate test and several regression analyses, we find that retained equity has a significantly negative impact on funding success; also, the support of business angels helps entrepreneurs to achieve a funding success. While winning grants is more likely to attract investors, there is no direct evidence associated with funding success. Furthermore, it turns out that intellectual property rights are not relevant for funding success. In an extension, we re-examine our analysis in the light of the Corona crisis by analysing 95 pitches from March to November 2020. We find no structural changes in relevance of the success factors.
A compact quad element MIMO antenna for LTE/5G (sub-6 GHz) applications
Authors: Singh Ajit Kumar , Mahto Santosh Kumar , Sinha Rashmi
Published: July 2022

In this paper, a compact I shaped monopole radiator with a dimension of 24 × 22 × 1.6 mm3 is proposed. The monopole radiator achieved an impedance bandwidth of 1.46 GHz (4.06–5.52 GHz) using partial ground plane. Further to cover the sub-6 GHz spectrum (3.4–3.6 GHz) for future 5G communications, a four-element multi-input multi-output (MIMO) antenna configuration is designed by utilizing the single element antenna. The operation bandwidth of 2.27 GHz (3.37–5.64 GHz) is enhanced by using a tapered microstrip feed line. Isolation is increased upto 40 dB over the operating band (3.37–5.64 GHz) by using a modified rectangular stub in the partial ground plane. This stub also provides a decoupling path and consequently limited amount of current couples to the neighbouring element due to surface waves. The modified stub suppress the surface waves and the near fields reducing the coupling between the antennas keeping it below −10 dB for the whole desired frequency range. Therefore, the proposed MIMO antenna achieved wide bandwidth of (3.37–5.64 GHz) and minimum isolation between antenna elements 1 & 4 is −10 dB in 3.4–3.6 GHz frequency band, whereas −15 dB between 3.8 and 5.64 GHz frequency band. The suggested MIMO antenna is designed on a FR4 substrate with a dielectric constant of 4.4 and a loss tangent of 0.02 and a 0.45λ
0 × 0.45λ
0 dimension. In terms of the envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), isolation between the ports, and channel capacity loss (CCL), the proposed antenna’s diversity performance characteristics are investigated and the obtained values are 0.04, 9.98, ±3, −11, −15 dB, 0.10 bits/s/Hz respectively. The antenna prototypes have been fabricated, and the measurements and simulations have been found to be in close agreement. Therefore, the proposed MIMO antenna covers n77/n78/n79 for 5G (sub-6 GHz) and LTE bands of 42/43/46.

This paper presents a graphene-based antenna array for terahertz (THz) applications. The suggested antenna array has four radiating square shaped patches fed by a coplanar waveguide (CPW) technique. The proposed antenna array operates at the three frequencies with operational bandwidths of 1.173–1.210 THz (at 1.19 THz), 1.270–1.320 THz (at 1.3 GHz), and 1.368–1.346 THz (at 1.4 GHz). The total area of the antenna array is reported as 1000 × 1000 µm2, printed on a Silicon substrate with a thickness of 20 µm and a dielectric constant of ϵ

r
 = 11.9. To enhance the structure’s performance and optimize the feeding network, a parametric analysis was performed using the FDTD technique. Furthermore, the key properties of the proposed antenna array, such as resonance frequency, peak gain, and radiation efficiency, may be changed by adjusting the chemical potentials of the graphene in the antenna array. The use of graphene’s chemical potential tuneability yields exceptional results comparing to the recent research outputs, with a peak gain and radiation efficiency of 10.45 dB and 70%, respectively. These results show the performance of the suggested design for constructing antenna arrays for use in THz applications.
Genealogies of reflexivity: register formations and the making of affective workers
Authors: Del Percio Alfonso
Published: July 2022

How has the ability to express reflexivity, including regulating affect, come to be part of the bundled self that workers are required to be? This paper offers a rigorous genealogical analysis of the multiple histories of knowledge and power that have informed the emergence and shaping of ‘reflexive registers,’ or socially typified ways of speaking and reflecting about oneself that stand for morally marked models of selfhood. It takes as a starting-point programs documented in my ethnography of employability programs in London, UK where workers of all sorts are asked to learn to examine their personalities and to express their feelings. It then draws on original historiographical and ethnographic data that allows documentation of the logics and circumstances informing the emergence and development of reflexivity as a resource for employability. It argues for an interdisciplinary understanding of reflexivity and its communicability that theorises the workers as products of history, capital, and affect.
Introduction: language, work and affective capitalism
Authors: Dlaske Kati , Del Percio Alfonso
Published: July 2022

This special issue contributes to scholarship on language and affective economy by exploring the role played by affect in shaping work and workers under current configurations of capitalism. We take as a starting point the observation of increased valorisation and instrumentalisation of affect in the contemporary phase of capitalism. In this editorial introduction to the special issue, we set the scene by first outlining our questions, aims and objectives. Subsequently, we situate the contribution made by this issue in a larger social theorisation of affect and capitalism, particularly the notion of affective capitalism, and reflect on how this theorisation can contribute to sociolinguistic scholarship on work. The introduction concludes with an outline of the articles in this special issue, highlighting the way, empirically and conceptually, each article contributes to our understanding of the intersections between language, work and affective capitalism.
The behavior of piled rafts in soft clay: Numerical investigation
Authors: Elsawwaf Mostafa , Shahien Marwan , Nasr Ahmed , Magdy Alaaeldin
Published: July 2022

This research aims to investigate the applicability and performance of piled rafts in soft clay. This aim has been achieved by studying how the pile length, pile number, raft-soil relative stiffness, and presence of a sand cushion beneath the raft would affect piled raft settlement, differential settlement, and load sharing. Piled rafts have been numerically simulated using PLAXIS 3D software. Experimental testing results were used to verify the numerical simulation. The portion of the load carried by the piles to the total applied load was represented by the load sharing ratio (GPR). The results indicated that with increasing pile length and number, settlement and differential settlement decreased. It was also noticed that with increasing raft-soil relative stiffness, the differential settlement decreased. The GPR decreased with increasing thickness and relative density of the sand cushion, whereas it increased with increasing pile length and number. This increase in GPR was 13.7, 36, and 58% with an increase in pile length to diameter ratio from 10 to 30 for the number of piles 4, 9, and 16, respectively. Additionally, the raft-soil relative stiffness was observed to have a marginal effect on the GPR.
Language teachers as eco-activists: From talking the talk to walking the walk
Authors: Maley Alan
Published: July 2022

The climate crisis has received a great deal of attention of late, yet its root causes go back to the last century and beyond. Also going back many years have been efforts to address the roots of the climate crisis. These efforts include the work of language teachers to research, create, trial, and share materials and pedagogical strategies for educating and mobilizing teachers, students, and other stakeholders to address the beliefs and practices that have led our species to the precipice of irredeemable disaster. This article seeks to serve as an annotated repository of works and collective wisdom of the author and colleagues, both near and far, as to how language teaching can accomplish its joint tasks of both facilitating student enjoyment of and expertise in their languages, and at the same time engaging students in fulfilling their responsibility as citizens of their home country and the world, a responsibility that has only grown more urgent due to the climate crisis. This repository is the result of 50 years of research, not with blinded control groups and statistical analysis (valuable though those methods can be), but of naturalistic investigation. The repository divides into three sections: Inspiration, Information, and Implementation. Strategies and ways that teachers have found useful for growing their own and their students’ knowledge of the causes of and possible solutions to the climate crisis are considered. The article ends with a poem by the author which addresses the important question of the role of the teacher in the classroom and beyond.

Composite sections are found to be a novel technique in modern day scenario of construction. This stands tall than the ordinary and conventional type of constructions. Columns as a structural element play a vital role in structural frame. This research comments on the behavior of composite columns. The main objective of this study is to analyze the behavior of steel-encased concrete composite columns as experimentally under axial compression and the mode of failure under ultimate failure and yield point. The steel-concrete composite system combines the formability and rigidity of reinforced concrete with the ductility and strength of structural steel to meet the demand for earthquake-resistant constructions. Three specimens were chosen for this study: one was a composite column, the other two were ordinary RC columns and structural steel columns. The raw materials' natural properties are assessed. As a result, material testing for cement, fine aggregate, and coarse aggregate was completed, as well as a concrete mix design. A comparative analysis of the local and post-local buckling behavior of different composite sections has been studied and the column sections have been designed according to Eurocode 4 (ENV 1994) to determine the plastic resistance of the section. These three specimens underwent compression test and the results are tabulated and compared. The corrosion resistance and fireproof nature (resistance to fire at higher temperatures) that are transmitted into the member are related to the steel being encased within the concrete. These are the two major drawbacks of any steel construction combined with an earthquake-resistant structure. Rather than a traditional steel construction, earthquake structures benefit from this type of load handling capabilities. The portion can be used before it completely collapses if proper design factors are taken into account.
Securitising the Present through the Prism of the Past: State-Building and the Legacy of Interventions in Kosovo and Serbia
Authors: Distler Werner
Published: July 2022

In this article, the author argues that political actors in Kosovo and Serbia, together with international actors from the UN, NATO, and the EU, have developed strategies of political communication in which the threat or promise of external intervention in Southeast European processes of state-building and state consolidation have been deeply inscribed. Based on a critical security studies theoretical framework, especially pragmatist securitisation, the author illustrates such “securitised state-building” with speech acts on interethnic violence, the Kosovo army, and NATO intervention commemorations. While securitised language does not necessarily lead to violence, actors with communicative strategies of segregation, confrontation, and even violence have proven more likely to be favoured by the governing mode of “securitised state-building”. Such a mode thereby may shape regional processes of de- and re-territorialisation in the future, too.
Vitamin Sea against Corruption: Informality and Corruption through the Interdisciplinary Lens
Authors: Buchenau Klaus , Frey Barbara , Jović Jovana , Lecić Miloš , Matković Damjan , Olaru Vasile Mihai
Published: July 2022

This conference report combines the latest theoretical developments within the areas of corruption and informality research in Southeastern Europe from the eighteenth until the twenty-first century with a presentation of the ongoing research conducted by the Regensburg Corruption Cluster and the inputs of some of the leading experts within these fields. The authors outline a practical interdisciplinary framework for developing a historical anthropology of corruption, by integrating knowledge and methods from various disciplines, such as history, linguistics and business studies. In doing so, they show how the ideological–normativistic approaches of the so-called “anticorruption consensus” can be overcome: by lowering the analytical scale to the level of informal practices and following their evolution through historical circumstances. This report also shows the persistent difficulties in establishing “ethical universalism” in Southeastern Europe with examples ranging from eighteenth-century Phanariot rule in Wallachia to twenty-first-century corruption scandals in Serbia and Croatia.
The 1999 NATO Intervention from a Comparative Perspective: An Introduction
Authors: Ristić Katarina , Satjukow Elisa
Published: July 2022

The special issue revisits the NATO intervention in the 1998–1999 Kosovo War by bringing together comparative perspectives from the war-affected states of the former Yugoslavia, on the one hand, and countries that supported or opposed NATO, on the other. The authors in this special issue look at the mediatization of the NATO intervention and its ambivalent legacies in and beyond the Yugoslav region. They provide insights into contested processes of mobilization for or against a military intervention in the Kosovo War, focusing on the case studies of Greece, Germany, and China. Moreover, they analyze the political legacies and mnemonic practices in the aftermath of this military intervention by highlighting the opposing narratives of memory politics in Kosovo and Serbia.

Authors: Brandstötter Cornelia , Grabenweger Reinhard , Frick Eckhard , Paal Piret
Published: July 2022

Hintergründe: Bisher in der Spiritual Care (SC) Forschung angewandte Maßnahmen ermöglichen es, Spiritualität, spirituelle Bedürfnisse und persönliches Wachstum von einzelnen Studierenden bzw. Schulungsteilnehmer/-innen zu messen und zu verstehen. Die Herausforderungen und Veränderungen auf Gruppen- und Organisationsebene werden jedoch weitgehend vernachlässigt.

Frage und Ziel der Studie: Ziel war zu untersuchen, ob sich die Kluft zwischen Aus- und Weiterbildung im Bereich SC und der Umsetzung in der Praxis in den letzten zehn Jahren verringert hat; aber auch die Maßnahmen und Möglichkeiten für eine nachhaltige Veränderung auf der Grundlage von Evidenz darzustellen.

Methode: Im Rahmen eines Regenschirm Reviews führten wir eine systematische Literaturrecherche in Datenbanken (PubMed, CINAHL, Web of Science) sowie eine Handsuche in Fachzeitschriften durch. In den Jahren 01/2012 bis 01/2022 publizierte, systematische Reviews wurden eingeschlossen. Insgesamt wurden zehn Reviews zur Beantwortung der Fragestellung herangezogen. Eine auf JBI-Kriterien basierte Qualitätsanalyse und Ergebnissynthese erfolgte.

Ergebnisse: Fünf Themen wurden hervorgehoben, die eine nachhaltige Übertragung von SC in die Praxis unterstützen: (1) Zusammenarbeit mit Seelsorger/-innen (2) Lernmethoden, insbesondere Anwendung von Gelerntem (3) Vorbilder/Mentor/-innen (4) Zeit, Beziehung und Arbeitsumfeld (5) SC Schulungsmodelle und –protokolle.

Schlussfolgerungen: Die Evaluationsergebnisse als Basis für Schulungskonzepte sind essenziell für langanhaltenden Fortschritt in diesem Bereich. Nicht nur positive, sondern auch negative oder fehlende Ergebnisse bedürfen gründlicher Analyse und Anpassung.

After unilateral lesion of the medial forebrain bundle by 6-OHDA rats exhibit lateralized deficits in spontaneous behavior or apomorphine-induced rotations. We investigated whether such lateralization is attenuated by either deep brain stimulation (DBS) or glutamatergic neurotransmission in the inferior colliculus (IC) of Wistar rats. Intracollicular DBS did not affect spontaneous lateralization but attenuated apomorphine-induced rotations. Spontaneous lateralization disappeared after either the glutamatergic antagonist MK-801 or the agonist NMDA microinjections into the IC. Apomorphine-induced rotations were potentiated by MK-801 but were not affected by NMDA intracollicular microinjection. After injecting a bidirectional neural tract tracer into the IC, cell bodies and/or axonal fibers were found in the periaqueductal gray matter, superior colliculus, substantia nigra, cuneiform nucleus, and pedunculo-pontine tegmental nucleus, suggesting the involvement of these structures in the motor improvement after IC manipulation. Importantly, the side of the IC microinjection regarding the lesion (ipsilateral or contralateral) is particularly important, and this effect may not involve the neostriatum directly.

Climate change in Nova Scotia: temperature increases from 1961 to 2020
Authors: Garbary David J. , Hill Nicholas M.
Published: July 2022

An analysis of temperature in Nova Scotia, using climate normals for 1961-1990 and temperature records from 1961 to 2020, is presented for 16 sites across the province. These records show a slight warming trend in the first 40 years from 6.0 ± 0.5 °C (1961-1990), followed by a more significant increase in average temperature post-1990 of 1.0 °C to 6.7 ± 0.5 °C, and to 7.0 ± 0.5 in the post-1998 period. A jump in average temperature in 1998 is such that in only a few following years did the mean annual temperature fall below the average annual temperature for the previous period. A step change was coincident with La Niña events and increasing Atlantic Ocean temperatures associated with a shift of the Atlantic Multi-decadal Oscillation into a positive phase. The increase in mean monthly temperatures was more apparent in the Autumn when first frosts were later and there were fewer days with frost. This led to a significant increase in continuous frost-free days of 9.2 ± 7.9 days, with increases ranging from 0.4 to 30.6 days. Relative to other sites, Yarmouth had the smallest annual increase in mean temperature, of 0.5 °C, but this was associated with a major increase in continuous frost-free days, of 11.3. Because overall temperature change was based largely on a step change post-1998, rather than a continuous, gradual change (seen only in frost-free days), it is difficult to calculate a rate, or to predict future patterns of temperature increases. We suggest a significant influence of El Niño Southern Oscillation and Atlantic Multi-decadal Oscillation as potential contributors to the temperature increase. Increases in annual temperature and seasonality are discussed in terms of flowering phenology, including flowering in the Spring of 2021 when 31 species were blooming by the end of April.Keywords: climate change, climate normal, flowering phenology, Nova Scotia, temperature, weather
Parasitism of Brook Trout (Salvelinus fontinalis) during the first month post-emergence in streams in southwest Nova Scotia
Authors: LeBlanc Roland , MacMillan John L. , Marcogliese David J. , Cone David K.
Published: July 2022

Parasite recruitment of recently emerged fry of brook trout (Salvelinus fontinalis) in three streams in southwestern Nova Scotia was documented. In early April, fry appeared to leave the protective gravel redds parasite free but began acquiring parasites within the next 2-4 weeks, with prevalence of infections of any given species reaching 21 to 46% by mid-May. The initial infections involved 1) directly transmitted ectoparasites Gyrodactylus colemanensis and Salmincola edwardsii and 2) food-borne endoparasites (Echinorhynchus lateralis and Crepidostomum sp.). Colonizing parasites found in the first month post-emergence varied by locality: at Bangor Creek, it involved G. colemanensis, E. lateralis, and Crepidostomum sp., while at Germaine East, it involved only G. colemanensis and at Germaine North, only S. edwardsii. In each case, the initial colonizers reflected what was abundant locally and within a regional pool of 10 parasite species. Localized skin thickening and sometimes tissue erosion were evident at sites of attachment of S. edwardsii. Minor disruption of fin margins was seen with G. colemanensis. No pathology was associated with E. lateralis nor Crepidostomum sp. The predictable timing of emergence and ease of sampling fry of S. fontinalis near redds represents a convenient system with which to assess impact of initial parasitism on fish recruitment at the local level. Keywords: Echinorhynchus, Gyrodactylus, initial parasite colonization, regional parasite pool, Salmincola
