The purpose of this research was to investigate the relationship between patient experience and satisfaction and patient loyalty utilizing Halodoc and Alodokter. Direct and indirect impacts between study variables are among the topics that have been investigated. A cross-sectional research approach was employed in this study, which combined quantitative descriptive analysis with an analytic survey. The research included 500 patients who used Halodoc and another 500 individuals who used Alodokter as part of their treatment. The study sample consisted of 286 individuals, including 143 patients who used Halodoc and 143 patients who used Alodokter, who were selected using the proportionate sampling method. An association between patient experience and patient satisfaction was found to be significant (p-value 0.0000.05), while an association between patient experience and patient loyalty was found to be significant (p-value0.0000.05). As an added bonus, there was a direct relationship between customer happiness and customer loyalty, with a p-value of 0.0000.05. The indirect impact of patient experience on patient loyalty and patient satisfaction as a mediator, however, was shown to be statistically significant (p-value = 0.000 0.05) and was found to be significant. This research suggests that telemedicine services are being used more often in health agencies during the COVID-19 pandemic because of the potential advantages it provides, such as its efficiency and the impact it has on patient happiness and loyalty, according to the findings.

Published: July 2021

Introduction: Neuroanatomy is considered as difficult subject as it consists mostly of complicated microscopic structures. However, understanding of the subject structure is very important for nursing students to know its functions and dysfunctions for enhancing nursing practices. To date, teaching neuroanatomy relies heavily on illustrations and the most common way is by using PowerPoint slides, but teachers are often faced with dilemma on how to use illustrations effectively. Therefore, this study was conducted to assess the effectiveness of different ways of presenting neuroanatomy illustrations in PowerPoint slides on nursing students’ short[1]term learning memory.
Methods: The quasi-experimental study was conducted at Faculty of Nursing and Public Health, Khesar Gyalpo University of Medical Sciences of Bhutan between June 2020 and November 2020 by comparing an Experimental (n= 70) and a Control group (n= 69) of first year nursing students for their ability to answer questions based on those seven-way slides. Independent sample t-test was used for statistical analysis.
Results: Significant difference was found at 95% CI between the performance of the Experimental and Control groups regarding Way 1 (Sequencing of labels) and Way 6 (Magnifying from the original structure) of presentation (tWay 1(135.99) = 2.695, p= .008, d = .458, 95% CI = [0.059, .385]; tWay 6(135.61) = 2.351, p= .020, d = .399, 95% CI = .031, .355], respectively).
Conclusions: The use of different ways like sequencing the labels and magnifying from the original structure of presenting illustration in PowerPoint slides are found to be helpful in increasing short[1]term memory in students.

Published: July 2021

Due to the large disposal of locally industrial wastes and the shortage of natural resources, turning industrial by-products into green artificial materials has been attracting many researchers in the world. Following this trend, this study evaluated the potential application of self-produced artificial sand (AS) in the production of green mortar. The AS was produced by the alkali-activated method using a mixture of 36.4% fly ash, 36.4% slag, 3.5% 10M NaOH solution, 11% Na2SiO3 solution, and 12.7% water. The mortar mixtures were designed based on the densified mixture design algorithm with the incorporation of the AS as the substitution of natural sand (NS) by 0 – 100 wt.% (interval of 20%). The engineering properties of the mortar samples in both fresh and hardened states were evaluated through the tests of workability, compressive strength (CS), water absorption (WA), and shrinkage/ expansion. The experimental results showed that the mortar sample incorporating 20% of AS to replace NS performed superior engineering properties in comparison to other samples. Further increasing the AS content generally caused a negative impact on the mortar’s performance. Increasing AS content beyond 20% systematically decreased the CS while both WA and expansion were increased noticeably. However, the properties of the green mortar produced for this study satisfied all of the requirements of the official Vietnamese standards. Thus, the research results further confirmed a great potential in producing green mortar using AS to either partially or fully replacement of NS. In addition, the use of AS greatly contributes to not only saving natural resources but also limiting the negative effects on the environment due to the exploitation and use of naturally sourced materials.

Teaching is a noble profession which requires special skills for the transformation of
knowledge from teaching domain to the learning domain. This profession requires deep
knowledge, dedication in teaching, encouragement, and control over the activities of the learning domain, providing the knowledge to the learning domain, teaching the discipline ,behavior and smart skills as out of box teaching subjects. The teacher has to continuously upgrade himself in discharging the knowledge because whatever he has learned in his learning domain might be outdated. The Knowledge is always updating and it is the responsibility of all the teachers to update their knowledge so that they can effectively transform the same to the learning domain. The knowledge transformation in technical subject needs a rather different methodology than the traditional classroom based teaching. The subject like Software Engineering needs a different method of teaching than the traditional classroom based teaching. In this subject the learning domain should be active in looking into the various aspects of the software development. In this subject, the traditional classroom based teaching
does not transform the knowledge to the learning domain because the learning domain cannot follow the subject since the domain does not have any idea about the subject. This paper explains the need for active teaching in software engineering where in the learning domain has to be active than the teaching domain. The teaching domain has to concentrate on various concepts which are supposed to be given to the learning domain and guide the learning domain how to get the knowledge, effective use of the available technology and its adoption at the right place. The objective of this paper is how to convert the learning domain into smart learning domain. This paper strongly recommends the case study based teaching and learning practice than the traditional unidirectional classroom teaching.

Published: July 2021

Grain sorghum production has expanded during the off-season when rainfall oscillates and becomes insufficient. Aiming to obtain better adapted cultivars, breeding programs have sought new combinations of hybrids with earliness, high grain yield, and ideal plant height for harvesting. This study aimed to estimate de combining ability of grain sorghum lines, proposing a breeding strategy, to identify hybrids gathering high yield, earliness, and desired plant height. Thirty-six hybrids from crosses of 12 lines were evaluated at two sites in the Brazilian region known as Cerrado biome. The evaluated traits were: days to flowering, plant height, and grain yield. For the diallel analysis, Method 4 of Griffing adapted to partial diallel was adopted. By combining ability analysis, we identified promising lines to be used as parents to obtain more yielding, early, and ideal height hybrids. The findings allowed us to propose a breeding strategy, in which complex crosses should be performed to gather favorable alleles in new restorer and male-sterile lines. The hybrids 7, 9, 19, and 22 are the most suitable for growing in the evaluated sites.

Highlights:

Combining ability analysis allows the identification of promising parents to be used in grain sorghum breeding program.

Favorable alleles for each trait are contained in different parents, which makes gene pyramiding a necessary strategy to simultaneously gathering earliness, plant height suitable for harvesting, and high yield in a single hybrid.

To improve the R lines, the cross between M2 (good donor for shorter height) x M5 (good donor for earliness) should be performed, and the hybrid resulting from M2xM5 can be crossed with the M4 line (good donor for high grain yield).

The hybrid generated by the cross F1-B x F4-B (high earliness) should be crossed with the hybrid derived from F6-B x F5-B (shorter height), and the hybrid resulting should be crossed with the hybrid generated by F2-B x F3-B (high grain yield).

Published: July 2021

It is important to look for alternative substrates to replace non-renewable resources such as peat used in growing media in horticulture. The aim of this work was to evaluate if the compost of pear and apple pomace could be used as an alternative to a commercial substrate for the production of tomato seedlings. Two experiments were carried out on trays with alveoli of 100 cm3 (experiment 1) and 30 cm3 (experiment 2). In experiment 1, three substrates were used: commercial substrate (CS), mixture of CS and pomace compost (CS+C) and pure compost (C). In experiment 2 a fourth treatment with a mixture of compost and perlite (C+P) was incorporated. The obtained results indicate that the development of the seedlings using CS+C and CS as a substrate was similar in cells of 100 cm3 and higher in cells of 30 cm3. In addition, the growth of seedlings on C+P in relation to CS showed similar or higher values in some variables. These results indicate that it would be feasible to replace the use of non-renewable resources such as peat in the production of tomato seedlings by a product obtained from a residue.

Tomato seedling growth was evaluated on trays with 100 cm3 alveoli and 30 cm3 alveoli on different substrates mixtures: commercial substrate (CS), mixture of CS and pomace compost (CS+C), pure compost (C) and mixture of compost and perlite (C+P).

Highlights

Seedling development using CS+C and CS as substrates was similar in cells of 100 cm3 and higher in cells of 30 cm3.

Seedling growth on C+P in relation to CS, showed similar or higher values for some variables such as root dry weight, shoot dry weight, stem diameter and shoot height.

In 30 cm3 cell trays of the compost and perlite treatment (3:1 v/v), obtained seedling quality would enable a high post-transplant survival percentage.

Pear and apple pomace compost may be an alternative to a commercial substrate containing peat for tomato seedlings production (Lycopersicon esculentum Mill.).

Published: July 2021

Analysis of emission allowances prices has important environmental and political connotations. This article aimed to identifying the possible variables that may influence their behaviour and studied their relationship with fundamental factors: energy (Brent petroleum, Gas, Coal) and economy (Industrial Production Index, Baltic Dry Index, Purchasing Managers Index). With the objective of analyzing possible mutual interactions, Multivariate VAR or Error Correction Models (VECM), were applied. The information analysed derived from different sources (World Bank, Sendeco2 and various financial websites). The results obtained showed, not only the influence of past prices on the emission allowances actual price, but also the interaction with energetic and economic variables.

Highlights

Estimation of time series interrelations through VAR models.

There is relationship of the emission allowances price with their past values.

The energy variables are factors important to also explain the behavior of the emission allowances price.

The economic variables are hardly significant except for the Dry Baltic Index.

Authors: Holguín-Peña Ramon Jaime , Medina-Hernández Diana , Vázquez-Islas Grecia , Nieto-Navarro Francisco , Puente Edgar Omar
Published: July 2021

Certified-organic farming systems in Baja California Peninsula and Northwest Mexico are nationally and globally recognized, especially due to the production of vegetables and aromatic herbs under protected agriculture systems. Based on the background of some species of the flora of Baja California Sur (BCS) to inhibit a diversity of microorganisms, the effect of 22 medicinal plants of the region was explored to know the in vitro activity against the fungus Fusarium oxysporum f. sp. basilici isolated from basil (Ocimum basilicum L.). The plants processed as crude ethanolic and aqueous extracts were analyzed in duplicate (three replicates) evaluating the inhibition of mycelial growth and spore germination. In mycelial inhibition test, all plants extracts (1000 mg L-1) showed an effectiveness of 11 to 40% to inhibit F. oxysporum. The most effective plant extracts according to 50% effective inhibition dose (ED50), were Larrea tridentata, Hymenoclea monogyra and Lippia palmeri with an ED50 of 220, 303 and 3000 mg L-1, respectively. Tukey’s PostHoc tests indicated that H. monogyra and L. tridentata are ten times (ED50 <300 mg L-1) more effective than L. palmeri (ED50 3000 mg L-1). In addition, the dose-response trend analyzes according to the logarithmic-logistic model (drc packages), showed the maximum slope values ​​between 100 and 1000 mg L-1. In the spore germination inhibition tests, most ethanolic extracts (5000 mg L-1) showed an effectiveness between 21 and 80%. The results of this study demonstrated that the inhibitory potential of these plants used in BCS traditional medicine are a viable alternative for the control of F. oxysporum f. sp. basilici in organic basil production systems.
Highlights

22 medicinal native plants from the Baja California peninsula can effectively inhibit (in vitro) oxysporum f. sp. basilica.

The most effective species were Larrea tridentata, Hymenoclea monogyra and Lippia palmeri with a mycelial growth inhibition (ED50) of 220, 300 and 3000 mg L-1, respectively.

In vitro effectiveness of Fusarium-growth inhibition of medicinal plants of BCS were in ED50 ranges from 220 to 3000 mg L-1.

Creosote bush (L. tridentata) extract at a dose of 5000 mg L-1 can inhibit the fungal sporulation by up 80%.

The ethanol-aqueous extract of the medicinal plants of BCS have the potential to be used for long-term control of the fusariosis disease in basil.

Published: July 2021

Argentina is the second largest peanut (Arachis hypogaea L.) exporter in the world. The main peanut pest in our country is the two-spotted spider mite (Tetranychus urticae Koch 1836). To date, there is no validated method to quantify this pest. The aim of this work was to develop and validate a logarithmic diagrammatic scale to assess damage by the two-spotted spider mite in peanut. In 2015-16, 200 leaflets were collected from a plot infested with the pest. Damaged leaf area (DLA) was calculated using SisCob software. Six-, seven-, eight- and nine-class scales were proposed. Mean values for each class and scale were obtained with 2-LOG. Leaflets were analyzed by 13 raters who used the four proposed scales. Precision and accuracy were determined by simple linear regression between the DLA and estimated damaged leaf area. Reproducibility was determined by linear regression between estimates of raters combined in pairs. The seven-class scale was the best validated one for all the parameters. Most raters showed constant deviations and overestimated DLA, whereas only one rater presented systematic deviations. This seven-class scale is the first developed and validated one to evaluate two-spotted spider mite damage to peanut in Argentina.

Highlights

According to the validation results, the seven-class diagrammatic scale was the best one in terms of accuracy, precision and reproducibility with values above 0.80, 0.75 and 0.75 respectively.

The scales are useful tools for pest assessment, fundamental parameters for integrated pest management.

The seven-class scale is the first one developed and validated for evaluating damage by the two-spotted spider mite in peanut crop in Argentina.

With this scale a loss function will be calculate which will allow the estimation of the EIL of this pest.

Published: July 2021

Tomatoes are affected by fungi of the genera Fusarium and Alternaria, reducing the quantity and quality of the fruit.Since plant extracts are an alternative for the control of phytopathogenic fungi, the antifungal effect of Salmea scandens extracts was evaluated against Fusarium oxysporum and Alternaria solani and the functional groups of the chemical constituents were identified.The aqueous extracts were obtained by three techniques (soxhlet, assisted ultrasound and maceration) and three solvents (water, acetone and ethyl ether), these were evaluated against F. oxysporum in poisoned medium and A. solani in tomato fruit. The functional groups were identified by the Fourier Transform Infrared Spectroscopy (FTIR) technique. The best extraction technique for S. scandenswas soxhlet with all three solvents. Maceration-acetone extracts at concentrations of 4000 and 5000 ppm showed increased antifungal activity against F. oxysporum and A. solani. The FTIR analysis confirmed the presence of carboxylic acids, aldehydes, ketones and aromatic compounds as the possible responsible for the antifungal activity.S. scandensextracts have a high potential to be used as a preventive treatment in the control of F. oxysporum and A. solani.

Highlights

The highest mass/volume extraction efficiency yield was with the soxhlet technique using water as a solvent.

Extracts obtained by maceration-acetone technique, caused the strongest Fusarium oxysporum inhibition.

The maceration-acetone extract at 5000 ppm, showed higher inhibition of A. solani mycelial growth than the commercial fungicide Hymexazol.

Authors: Eck Christopher J. , Layfield K. Dale , DiBenedetto Catherine A. , Gore Jason
Published: July 2021

The COVID-19 pandemic forced educators to move course delivery to online learning with little or no advanced training. One of the immediate concerns of the online course delivery was readiness in using the synchronous learning tools available to school districts. Additionally, moving all students to online learning environments presented a challenge for those teachers who knew little about accessibility tools. The purpose of this study was to assess the awareness and self-perceived competence levels of SBAE teachers in South Carolina related to synchronous online instruction and application of accessibility tools during the COVID-19 pandemic. The majority of the teachers indicated they used Google Meet as the institution's synchronous delivery platform. Of those using Google Meet, their ability to use the mobile application to start meetings and use virtual backgrounds was low. The second most used synchronous delivery platform was Zoom. Some of the skill gaps SBAE teachers listed while using Zoom included breakout rooms, the polling feature, and removing unwanted participants. SBAE teachers reported very low competence in using accessibility features provided in Microsoft Word and PowerPoint applications. Recommendations included future in-service training for SBAE teachers in using advanced levels of Zoom, Google Meet, and WebEx features. Also, training for SBAE teachers on the importance of accessibility and the tools provided is warranted. Faculty teaching educational technologies in pre service programs for SBAE teachers are also encouraged to adapt curricula to support these skills.
SVM: Object Detection using Rotation-Invariant and Fisher Discriminative Convolutional Neural Networks
Authors: Pavithra V. , Kannan R.
Published: July 2021

With the touchy development of information, the multi-see information is broadly utilized in numerous fields, for example, information mining, AI, PC vision, etc. Since such information consistently has a perplexing construction, for example numerous classes, numerous viewpoints of portrayal and high measurement, how to detail a precise and solid system for the multi-see order is an exceptionally difficult assignment. In this paper, we propose a novel multi-see characterization technique by utilizing various multi-class Backing Vector Machines (SVMs) with a novel shared system. Here each multi-class SVM installs the scaling component to renewedly change the weight assignment, everything being equal, which is useful to feature more significant and discriminative highlights. Besides, we receive the choice capacity esteems to incorporate different multi-class students and present the certainty score across various classes to decide the last characterization result. Moreover, through a progression of the numerical derivation, we connect the proposed model with the reasonable issue and address it through a rotating emphasis improvement strategy. We assess the proposed strategy on a few picture and face datasets, and the test results exhibit that our proposed technique performs better compared to other cutting edge learning calculations.

Diabetes mellitus (DM) is characterized as a gathering of metabolic issues applying critical tension on human wellbeing around the world. DM is a persistent sickness portrayed by hyperglycemia and it might cause numerous inconveniences. To forestall this issue, to break down the given medical clinic dataset by directed AI technique(SMLT) with catch a few data resembles, variable ID, uni-variate examination, bi-variate and multi-variate investigation, missing worth therapies and dissect the information approval, information cleaning/getting ready and information perception will be done on the whole given dataset. Our analysis provides a comprehensive guide to sensitivity analysis of model parameters with regard to performance in prediction of diabetic patients by given attributes of dataset with evaluation of GUI based user interface diabetes attribute prediction. Additionally, it observes to lead an increase the highest accuracy in diabetic prediction of attributes by a significantly better classification report, identify the confusion matrix and to categorizing data from priority and the result shows that the effectiveness of the proposed machine learning algorithm technique can be compared with best accuracy with precision, Recall and F1 Score.
« Le traducteur est un "chercheur" d’un genre particulier »
Authors: Sécardin Olivier
Published: July 2021

Philippe Noble est traducteur littéraire. On lui doit notamment la traduction d’œuvres d’Etty Hillesum, Harry Mulisch et Cees Nooteboom. Après avoir mené une carrière à l’Université, Philippe Noble s’est engagé au service des Affaires étrangères et de la diplomatie culturelle – il a été conseiller culturel à La Haye (2000-2004) et à Vienne (2008-2011), directeur de la Maison Descartes et du Réseau franco-néerlandais. Il est aussi directeur de la collection « lettres néerlandaises » chez Actes Sud. Nous nous sommes entretenus avec lui à propos de son travail de « médiateur culturel » entre la France et les Pays-Bas. L’entretien est suivi d’une bibliographie com­plète des traductions réali­sées par Philippe Noble.
Éditions Verdier : un lieu, un projet, un trajet collectif
Authors: Van Montfrans Manet
Published: July 2021

Verdier est une maison d’édition indépendante avec un siège social à Lagrasse, dans l’Aude, et une permanence à Paris. La maison est aujourd’hui co-gérée par Colette Olive et Michèle Planel. Ensemble avec Gerard Bobillier et Benoît Rivéro (qui quittera le groupe assez vite), elles ont été à l’origine d’une aventure éditoriale extra­ordinaire. Les titres (environ 700) du catalogue édité en 2019 à l’occasion des quarante années d’existence se regroupent en cinq grandes rubriques : littérature, sciences humaines, philosophie, art, architecture et cinéma, spiritualités.

À la fondation de la maison en 1979, les éditeurs ont laissé derrière eux leur militan­tisme politique, sans pour autant renier leur volonté de contribuer à transformer sinon le monde, du moins les consciences. Le cata­logue témoigne d'une exigence sans faille ainsi que d’une extraordinaire ouverture au monde. Né en plein cœur des Corbières, Verdier a voulu se situer au croisement de différentes cultures. En font preuve les collections de traductions de plusieurs langues étrangères, dont l’arabe et l’hébreu. Le fonds comporte des textes fonda­teurs tels le Guide des égarés de Moïse Maïmonide, Les Batailles nocturnes de Carlo Ginzburg, Les récits de la Kolyma (2003) de Varlam Chalamov, mais il montre aussi l’émergence d’auteurs français importants, tels Pierre Michon et Pierre Bergounioux. 

Comment une maison d’édition qui se caractérise par un fonds exigeant a-t-elle réussi à garder son indé­pendance sans faire de concessions ? Comment a-t-elle su survivre aux naufrages économiques, éviter d’être écrasée dans des reprises commerciales incer­taines ? Comment a-t-elle fait face à la transformation radi­cale de l’industrie du livre, c’est-à-dire sa fabrication, sa diffusion et sa médiatisation ? Ce sont les questions que nous avons posées à Colette Olive, dans le cadre d’un entretien visant à mettre en lumière le travail accompli durant une quarantaine d’années par cette maison d’édition singu­lière.
QUE É DEUS?
Authors: Santos Enio Rodovalho dos
Published: July 2021

Os conceitos de ciência, religiosidade e Deus são palco de reflexões desde quando o ser humano começou a usar o seu pensamento de forma racional. A humanidade, ao longo dos anos, desenvolveu várias teorias a respeito dos temas sem conseguir de fato chegar a um denominador comum. Em muitos momentos históricos, a ciência avançou em conflito com a religião. Com este trabalho, temos o objetivo de resgatar conceitos de alguns grandes cientistas da história e levantar algumas hipóteses e interpretações, no intuito de contribuir para um melhor entendimento do tema e tentar responder à célebre pergunta: o que é Deus?

Origin, transport, and retention of fluvial sedimentary organic matter in South Africa's largest freshwater wetland, Mkhuze Wetland System
Authors: Gensel Julia , Humphries Marc Steven , Zabel Matthias , Sebag David , Hahn Annette , Schefuß Enno
Published: July 2021

Abstract. Sedimentary organic matter (OM) analyses along a 130 km-long transect of the Mkhuze River from the Lebombo Mountains to its outlet into Lake St. Lucia, Africa’s most extensive estuarine system, revealed the present active trapping function of a terminal freshwater wetland. A combination of organic bulk parameters, thermal analyses, and determination of plant waxes, and their corresponding stable carbon (δ13C) and hydrogen (δD) isotopic signatures in surface sediments and local plant species enabled characterization and comparison of sedimentary OM in terms of stability, degradation status, sources, and sinks within and among the respective sub-environments of the Mkhuze Wetland System. This approach showed that fluvial sedimentary OM originating from inland areas is mainly deposited on the floodplain and Mkhuze Swamps. In contrast to samples from upstream areas, a distinctly less degraded signature characterizes the sedimentary OM in the northern section of Lake St. Lucia. Although lake sedimentary plant waxes are similar in the observed wax distribution pattern and δ13C values, they exhibit considerably higher δD values. This offset in δD indicates that lakeshore vegetation dominates plant-derived sedimentary OM in the lake, elucidating the effective capturing of OM and its fate in a sub-tropical coastal freshwater wetland. These findings raise important constraints for environmental studies assuming watershed-integrated signals in sedimentary archives retrieved from downstream lakes or offshore.
HydroSat: a repository of global water cycle products from spaceborne geodetic sensors

Published: July 2021

Abstract. Against the backdrop of global change, both in terms of climate and demography, there is a pressing need for monitoring the global water cycle. The publicly available global database is very limited in its spatial and temporal coverage worldwide. Moreover, the acquisition of in situ data and their delivery to the database are in decline since the late 1970s, be it for economical or political reasons. Given the insufﬁcient monitoring from in situ gauge networks, and with no outlook for improvement, spaceborne approaches have been under investigation for some years now. Satellite-based Earth observation with its global coverage and homogeneous accuracy has been demonstrated to be a potential alternative to in situ measurements. This paper presents HydroSat as a repository of global water cycle products from spaceborne geodetic sensors. HydroSat provides time series and their uncertainty of: water level from satellite altimetry, surface water extent from satellite imagery, terrestrial water storage anomaly from satellite gravimetry, lake and reservoir water storage anomaly from a combination of satellite altimetry and imagery, and river discharge from either satellite altimetry or imagery. These products can contribute to understanding the global water cycle within the Earth system in several ways. They can act as inputs to hydrological models, they can play a complementary role to current and future spaceborne observations, and they can deﬁne indicators of the past and future state of the global freshwater system. The repository is publicly available through http://hydrosat.gis.uni-stuttgart.de.
Collection and analysis of a global marine phytoplankton primary production dataset
Authors: Mattei Francesco , Scardi Michele
Published: July 2021

Abstract. Phytoplankton primary production is a key oceanographic process. It has relationships with the marine food webs dynamics, the global carbon cycle and the Earth’s climate. The study of phytoplankton production on a global scale relies on indirect approaches due to field campaigns difficulties. Modelling approaches require in situ data for calibration and validation. In fact, the need for more phytoplankton primary production data was highlighted several times during the last decades. Most of the available primary production datasets are scattered in various repositories, reporting heterogeneous information and missing records. We decided to retrieve field measurements of marine phytoplankton production from several sources and create a homogeneous and ready to use dataset. We handled missing data and added variables related to primary production which were not present in the original datasets. Subsequently, we performed a general analysis of the highlighting the relationships between the variables from a numerical and an ecological perspective. Data paucity is one of the main issues hindering the comprehension of complex natural processes. We believe that an updated and improved global dataset, complemented by an analysis of its characteristics, can be of interest to anyone studying marine phytoplankton production and the processes related to it. The dataset described in this work is published in the PANGAEA repository. DOI: https://doi.pangaea.de/10.1594/PANGAEA.932417 (Mattei and Scardi, 2021)

The night writer: The emergence of nocturnal travel writing
Authors: Stubbs Ben
Published: July 2021

In 1762, the philosopher and writer Jean-Jacques Rousseau wrote in Emile (1979) that

we are blind half our lives because of what we miss during the night. The notion that the

night can offer a broader experience and understanding of people, culture and place is

one that is particularly relevant to travel writing and travel writers, though it is a

perspective that has not been widely studied. As such, this paper will explore the

development of nocturnal travel writing. This awareness begins with the influence of

the flâneur in Paris and London. The immersed perspective of the street wanderer

inspired many writers, including Charles Dickens, who later wrote Night Walks in 1861

of his nocturnal London walking. While technology and security diminished the writers’

fascination of the night in the later 19th and 20th centuries, it has re-emerged as an

important subgenre of contemporary travel writing. There is a range of diverse

examples of nocturnal travel writing in the 21st century focusing on nature, social and

cultural lives and non-English speaking countries. These examples present an

opportunity to push the authentic boundaries of the travel writing form in an era of

gimmicks and unimaginative storytelling. As a form which draws influence from the

flâneur, psychogeography and the literary pedigree of writers such as De Quincey and

Dickens, nocturnal travel writing offers the reader a new and imaginative rendering of

the ‘other’ within different places, cultures and temporal zones.
International solidarity, volunteer tourism and travel writing: Mexico and Central America in Spanish and English
Authors: Hanley Jane
Published: July 2021

This article discusses the intersection of ethnographic, reflexive and anecdotal styles in travel writing produced out of contemporary international volunteer tourism, and analyses the impact of volunteer tourism on the production of a narrating subject and on the representation of host communities. The comparison of a primary work in Spanish (Herminia Esteban’s 2004 Un viaje solidario) with one in English (Cate Kennedy’s 2005 Sing, and Don’t Cry) allows us to better understand the specific historical, cultural and linguistic dimensions of different routes and encounters, as well as travel writing’s potential – and its limitations – in expressing a broader critique of global inequality. The texts are analysed to foreground the quotidian aspects of mobility and degree of authorial transparency regarding the terms under which volunteer activities take place. Extending from this analysis of the authors’ reflexivity, awareness and expression of critical engagement, the article explores the nature of representation in the narration of encounters between privilege and poverty, and frames these in relation to the ethical dimensions of contemporary practices of solidarity-based volunteer travel.
