Do native bees have the potential to promote interspecific pollination in introduced Impatiens species?
Authors: Ugoletti Paola , Reidy Darren , Jones Michael B. , Stout Jane C.
Published: April 2019

Artificial introductions of non-native species by humans can remove geographical barriers between species. In the absence of reproductive barriers, closely related introduced taxa may be able to hybridize, resulting in the formation of novel genotypes. These may be more suited to the new environment than either of their parent taxa, and have the potential to become more invasive. We investigated potential reproductive barriers between the non-native invasive Impatiens glandulifera and its less aggressive non-native congener I. balfourii. We examined behaviour of pollinators, including their foraging preferences and whether they switched from one species to the other. Moreover, conspecific and interspecific artificial crosses were performed between these species and seed production and the germination success of hybrid seeds were assessed.Both I. balfourii and I. glandulifera had relatively long flowering periods which mostly overlapped. Insect visitors were observed to switch from flowers of one species to the other during a single foraging bout, confirming that natural pollen transfer between species is possible. Artificial interspecific pollination resulted in the production of seeds, suggesting the presence of incomplete reproductive barriers between the two species. However, hybrid seeds mostly failed to germinate making the production of invasive hybrids unlikely. Nevertheless, because of the prolific reproductive output of these species we would not exclude the possibility that some viable hybrid seeds could be formed and become established. Further investigation of the fitness of hybrid seeds is required as hybridisation may allow Impatiens to exploit different ecological niches.
Experimental pollinator decline affects plant reproduction and is mediated by plant mating system
Authors: Lundgren Rebekka , Lazáro Amparo , Totland Ørjan
Published: April 2019

There is growing concern that current pollinator decline will affect the reproduction of plant species, potentially driving a decline in plant population densities. We experimentally tested whether a reduction in flower visitation caused a reduction in fertilization rate in several species, and whether any reduction in fecundity of species depends on their degree of reproductive dependence on pollinators and their attractiveness for pollinators. We recorded visitation rate, fertilization rate, seed weight, flower size and density of nineteen insect-pollinated perennial herbs inside thirty 2 x 2 m dome-shaped cages covered with fishnet (experimental plots) and in thirty control plots in a Norwegian hay meadow. We used a bagging experiment to estimate the ability of the study species to produce seeds in the absence of pollinators. The visitation rate for fifteen of nineteen study species was lower inside cages than outside and only three of the fifteen species showed significantly reduced fertilization rates in the experimental plots. The magnitude of reduction in fertilization rate was positively related to the degree of pollinator dependence, but not to their attractiveness for pollinators or to the reduction in visitation rate. Seed weight was not affected by the experiment. The lack of an overall effect of reduced pollinator visitation on fertilization rate suggests that some species may be robust to a pollinator decline that could increase pollen limitation on plant reproduction. Our results suggest that species with greater pollinator dependence are more vulnerable to pollinator loss.
Spring foraging resources and the behaviour of pollinating insects in fixed dune ecosystems
Authors: O'Rourke Aoife T. , Fitzpatrick Una , Stout Jane C.
Published: April 2019

In temperate climates, foraging resources for pollinating insects are especially important in early spring when animals emerge from hibernation and initiate annual life cycles. One habitat, protected under EU law, which provides resources for a range of pollinating insects, but has received little research attention, is fixed (grey) dunes. Fixed dunes often contain creeping willow (Salix repens, Salicaceae), which may be an important early season resource for obligate flower visitors. We examined the springtime activity of flower visitors in fixed dune ecosystems in relation to sugar concentration and composition in nectar, composition of essential amino acids in pollen, and floral abundance. We also investigated whether the presence or absence of S. repens influenced the abundance and species richness of three obligate flower visiting guilds (solitary bees, bumblebees and hoverflies) in eight sites along the eastern and southern coasts of Ireland.
Higher insect visitation rates were observed to species whose nectar contained greater concentrations of glucose and fructose. Solitary bee visitation rates were related to % Essential Amino Acid (EAA) in pollen and floral species richness. Ulex europeaus, and S. repens were the most abundant flowering species, but visitation rates were not related to floral abundance. Higher abundances of bumblebees and hoverflies were discovered at sites where S. repens was present. This study raises further questions about the nutritional requirements and preferences of obligate flower visitors in fixed dune ecosystems in spring time.

This study aimed to evaluate the importance of wild bee and feral honeybee visits for cotton production on conventional and organic farms. Experiments were conducted in Brazil, on a conventional cotton farm in Mato Grosso state in the Amazon biome and on an organic farm in Paraíba state in the Caatinga biome. On the conventional farm, bee assemblage and cotton production were measured near to and far from natural vegetation. Bee richness, fibre fraction, seed number and yield (Kg/ha) were higher by 57.14, 1.95, 17.77 and 18.44% respectively in plots near natural vegetation, but bee abundance did not vary with distance to natural vegetation. On the organic farm, because the cropping area is surrounded by natural vegetation, pollination deficit was evaluated using an exclusion experiment where cotton production of flowers bagged to prevent bee visitation (spontaneous self-pollination) was compared to production of flowers open to bee visitation (open pollination). Open pollinated flowers had higher average boll weight, fibre weight and seed number. Although cotton is not directly dependent on bee pollination, bees increased cotton production on the organic farm by more than 12% for fibre weight and over 17% for seed number. Our data confirm the importance of maintaining communities of pollinators on cotton farms, especially for organic production.
Identification of Plant Species for Crop Pollinator Habitat Enhancement in the Northern Prairies
Authors: Robson Diana Bizecki
Published: April 2019

Wild pollinators have a positive impact on the productivity of insect-pollinated crops. Consequently, landowners are being encouraged to maintain and grow wildflower patches to provide habitat for important pollinators. Research on plant-pollinator interaction matrices indicates that a small number of “core” plants provide a disproportionately high amount of pollen and nectar to insects. This matrix data can be used to help design wildflower plantings that provide optimal resources for desirable pollinators. Existing interaction matrices from three tall grass prairie preserves in the northern prairies were used to identify core plant species that are visited by wild pollinators of a common insect-pollinated crop, namely canola (Brassica napus L.). The wildflower preferences of each insect taxon were determined using quantitative insect visitation and floral abundance data. Phenology data were used to calculate the degree of floral synchrony between the wildflowers and canola. Using this information I ranked the 41 wildflowers that share insect visitors with canola according to how useful they are for providing pollinators with forage before and after canola flowers. The top five species were smooth blue aster (Symphyotrichum laeve (L.) A. & D. Löve), stiff goldenrod (Solidago rigida L.), wild bergamot (Monarda fistulosa L.), purple prairie-clover (Dalea purpurea Vent.) and Lindley’s aster (Symphyotrichum ciliolatum (Lindl.) A. & D. Löve). By identifying the most important wild insects for crop pollination, and determining when there will be “pollen and nectar gaps”, appropriate plant species can be selected for companion plantings to increase pollinator populations and crop production.
Introduction to Special Issue of the Journal of Pollination Ecology on Crop Pollination Deficits
Authors: Gemmill-Herren Barbara , Biesmeijer Koos
Published: April 2019

While it is well recognised that pollination is an ecosystem service of vital importance to human well-being through its role in food production, it is still remarkable how little is known, on a crop-by-crop basis, about this role, and the extent and causes of declines in the service. Without better documentation of the specific contribution of pollination to crop yields, there have been mounting - and justified - questions about how relevant pollination may be to agricultural development and food security. In addition, the vast majority of studies of pollination services to crops have been carried out in Europe and North America; and certainly the problems we know to impact pollinators most severely – a high dependence on agricultural chemicals and monocropped landscapes offering little diet diversity to pollinators – are typical features of industrialised, Northern hemisphere agriculture.
Pollination deficit in open-field tomato crops (Solanum lycopersicum L., Solanaceae) in Rio de Janeiro state, Southeast Brazil

Published: April 2019

More than 70% of world’s crops benefit from biotic pollination, and bees are their main pollinators. Despite the fact that some of these insects have been broadly studied, understanding the interactions between plant crops and their pollinators with a local scale approach is necessary when aiming to apply proper protective and management measures to pollinators and their respective crops. In this context, we analyzed the pollination status of open-field tomato crops (Solanum lycopersicum L.), regarding fruit-set, visitation rate and the quality of fruits. We recorded the formation of fruits through spontaneous self-pollination and open-pollination, and the occurrence of pollinators in 24 areas of open-field tomato crops. We performed experiments of apomixis, spontaneous self-pollination, manual cross pollination and supplemental cross pollination (simulating the pollinator behavior) in a greenhouse. The fruit quality was evaluated according to circumference, weight, volume and number of seeds. Higher production of fruits after open-pollination compared to spontaneous self-pollination indicates the importance of pollinators to increment productivity of S. lycopersicum in the study area. The circumference and the number of seeds from tomatoes of the greenhouse plantation did not differ between spontaneous self-pollination and the manual cross pollination. In the open-field crops the number of seeds was higher for fruits resulting from open-pollination. Our results indicate that the importance of bees is mainly related to the increase in fruit production, thus incrementing the productivity of tomato crops.production, thus incrementing the productivity of tomato crops.

Canola crop productivity is benefited by bee pollination and it has been shown that bee communities can be affected by landscape composition. The aim of this study was to analyse the bee community and its relationship to canola seed production in agricultural areas. The density, abundance and richness of floral visitors of Brassica napus cultivar Hyola 61 in six commercial fields in southern Brazil were studied, and their relationships with seed production and the ratio of semi-natural, forested and agricultural areas surrounding the crops were examined. It was observed that canola fields of southern Brazil are surrounded by a homogeneous landscape dominated by agricultural areas. The survey of bees detected a low abundance and richness of native bees in contrast to the high abundance of Apis mellifera. Except for a negative correlation between the abundance of honey bees and the proportion of forested areas within a 2000 m radius from the field (R = -0.90; P = 0.012), no other correlations were found among bee abundance and richness and landscape composition. Although there was not a relationship between A. mellifera and seed set, there was a positive correlation between insect density and seed weight per plant (R = 0.87; P = 0.024). As honey bees were the most captured insect (79%), much of the pollination in this system was probably achieved by honey bees.
Citizen scientists document geographic patterns in pollinator communities
Authors: Parker Alison J , Thomson James D
Published: April 2019

It is widely recognized that plants are visited by a diverse community of pollinators that are highly variable in space and time, but biologists are often unable to investigate the pollinator climate across species’ entire ranges. To study the community of pollinators visiting the spring ephemerals Claytonia virginica and Claytonia caroliniana, we assembled a team of citizen scientists to monitor pollinator visitation to plants throughout the species’ ranges. Citizen scientists documented some interesting differences in pollinator communities; specifically, that western C. virginica and C. caroliniana populations are visited more often by the pollen specialist bee Andrena erigeniae and southern populations are visited more often by the bombyliid fly Bombylius major. Differences in pollinator communities throughout the plants’ range will have implications for the ecology and evolution of a plant species, including that differences may affect the male fitness of individual plants or the reproductive success of plant populations, or both.
Low overnight temperatures delay ‘Hass’ avocado (Persea americana) female flower opening, leading to nocturnal flowering
Authors: Pattemore David Errol , Buxton Max N , Cutting Brian T , McBrydie Heather M , Goodwin Robert Mark , Dag Arnon
Published: April 2019

Avocado (Persea americana) has synchronously protogynous flowers: flowers open first in female phase before closing and opening the next day in male phase. Cultivars are grouped based on whether the flowers typically first open in female phase in the morning (type A), or in the afternoon (type B). However, it is known that environmental factors can alter the timing of flower opening, with cold temperatures being shown to affect the timing of flowering. The aim of this study was to investigate how low spring temperatures in New Zealand affect the flowering cycle of commercial avocado cultivars, focusing primarily on the receptive female phase of ‘Hass’, a type A cultivar. Time-lapse photography was used to assess flower opening times of ‘Hass’ over three years. Decreasing minimum overnight temperatures were associated with a delay in the timing of ‘Hass’ female flower phases and resulted in nocturnal flowering of both male and female phase flowers.  We recorded insects visiting female flowers at night, and some nocturnal flower visitors collected were carrying avocado pollen. Our study suggests that nocturnal pollination needs to be considered for avocados grown in temperate regions. Furthermore, as the timing of the female phase of ‘Hass’ varied significantly with overnight temperature, the activity patterns of potential pollinators need to be considered to ensure adequate pollinator activity across the range of times in which ‘Hass’ flowers are receptive.
Movements of floral parts and roles of the tooth on the column wall of Bulbophyllum praetervisum (Orchidaceae) flower in pollination by Dacini fruit flies (Diptera: Tephritidae)
Authors: Tan Keng Hong , Tan Lin Tze
Published: April 2019

Bulbophyllum is the largest genus of the orchid family, with about 2000 species that are mainly pollinated by flies. Flowers of many Bulbophyllum species under the Sections Sestochilos and Beccariana specifically attract Dacini fruit flies, Bactrocera and Zeugodacus species, as pollinators. Non-nectar producing and non-resupinate solitary flowers of Bu. pratervisum emit specific and pleasant floral fragrances to specifically attract and reward male fruit flies. Slippery surfaces on their lateral sepals aid in pollination. Although pollinia removal by male fruit flies has been observed frequently, deposition of pollinia to complete pollination (by two males of Ba. albistrigata and Z. caudatus) has only been observed recently. Field observations show two previously unreported movements of floral parts – a) petals and medial sepal during daily closing and reopening of flowers, and b) the spring-loaded and hinged lip during removal and deposition of pollinia by a male fruit fly. Additionally, a third (novel) movement has been observed, either when the flower closes for the night to protect the stigma, or after a fly has deposited the pollinia onto the stigma, the 'acute tooth' on each column wall folds inwards specifically to secure the newly deposited pollinia.
Busier bees: increasing nest traffic in commercial bumblebee colonies
Authors: Martin Callum Douglas , Toner Callum , Fountain Michelle , Brown Mark
Published: April 2019

Commercially-reared bumblebee colonies contribute to the pollination of crops globally. If the efficiency of commercial colonies at providing pollination services could be increased, it would have implications for agricultural outputs. Commercial colonies are sold with an internal nectar reservoir on which bees can forage from within the nest. Nectar stores in naturally-produced nectar pots of colonies can affect forager recruitment and activity outside the nest. Thus, it is possible that artificial nectar reservoirs could impact the foraging activity of colonies. To investigate this, commercial Bombus terrestris audax colonies were placed in a university parkland campus. Colonies were split into three treatment groups: those with (1) access to an unaltered nectar reservoir; (2) access to a diluted reservoir; and (3) no reservoir access. Foraging observations were made for all colonies over a 19-day period. The mass of each colony was measured and demographic data were collected. Colonies with diluted reservoirs had 131% and 39% more bees entering and leaving than colonies with no reservoir access and unaltered reservoirs respectively. Both treatments with access to a nectar reservoir gained more mass, had a higher proportion of pollen foraging bees, and had more workers, males, larvae and pupae, than colonies with no access to a reservoir. These results demonstrate that manipulating the availability and concentration of internal nectar reservoirs of commercial B. terrestris colonies significantly affects the number of bees entering and leaving the colony. Dilution of the nectar reservoir could be a strategy for increasing the pollination services commercial colonies provide to crops. Further research in commercial crops is required before such a strategy could be implemented on farms.
Implications of Updating Digital Literacy – A Case Study in an Optometric Curriculum

Published: April 2019

Aim/Purpose: The aim of this project was to explore a method to enable an updated under-standing of digital literacy to be implemented in curricula in an environment of an existing, but outdated, understanding of digital literacy.
.
Background: The changing healthcare environment increasingly emphasizes the importance of digital literacy skills; therefore academics in the optometry discipline at Deakin University sought to better understand where digital literacy skills were taught in their program, and whether delivery was implicit or explicit.

Methodology: This case study describes a systematic review of the optometric curriculum to first identify where and what digital literacy skills are currently being addressed in the curriculum, identify the gaps, and develop a strategy to address the gaps.

Contribution: The main outcome of this work is the development of a spiraling curriculum to support the development of digital literacy skills required in later units of the program and for clinical practice post-graduation.

Findings: Although the definition of digital literacy may be outdated, the digital literacy capabilities being addressed in the curriculum had grown as digital technology use by staff and students had expanded. This, together with the realization that students were not as digitally capable as expected, indicated that teaching digital literacy skills needed to be made overt throughout the curriculum.

Recommendations for Practitioners: The process developed through this case study provides a strong foundation for course teams, curriculum developers and educational designers to efficiently analyze digital literacy expectations in existing, accredited health-related curricula and improve the curricula by more overtly embedding digital literacy teaching into it.

Impact on Society: Graduates of the amended program of study are expected to be better prepared to undertake their future careers in a digitally enhanced and disrupted environment.

Future Research: The framework will be used to explore digital literacy teaching practices in other disciplines. A systematic evaluation will be undertaken to identify the benefits and short comings of using the framework. The elements that make up the new definition of digital literacy need to be better articulated to allow curriculum developers to be better informed as to how to interpret the framework in their context.

Emergent Change: A Network Analysis of Elementary Teachers’ Learning About English Learner Instruction
Authors: Hopkins Megan , Gluckman Maxie , Vahdani Tara
Published: April 2019

We study how a suburban U.S. district in the early stages of demographic change developed systems of support for teachers of English learners (ELs). Using district- and school-level social network and interview data, we examine elementary teachers’ EL-related professional learning opportunities, and how district and school organizational contexts enabled or constrained these opportunities. We find that the separation of language and content at the district level limited teachers’ learning opportunities, yet school leaders mitigated this separation by implementing structures that fostered norms of shared responsibility and collaborative teaching. Findings highlight the relevance of an organizational perspective for understanding how suburban districts respond to demographic change, and have implications for policymakers and practitioners with respect to creating inclusive environments for ELs.
Bucher et al. Personality traits and treatment outcomes meta-analysis
Authors: Bucher Meredith , Suzuki Takakuni , Samuel Douglas
Published: April 2019

Personality traits have been hypothesized to be clinically useful for diagnosis, client conceptualization, treatment planning, as well as for predicting treatment outcomes. Although several studies examined the relation between personality traits and specific therapy outcomes, this literature has not yet been systematically reviewed. Thus, the purpose of the current study was to investigate the relations between personality traits and various therapeutic outcomes. Traits were organized via the domains of the five-factor model to provide a common framework for interpreting effects. Across 99 studies (N=107,206), overall findings indicated that traits were systematically related to outcomes, with many specific relations congruent with theorized predictions. Generally, lower levels of neuroticism and higher levels of extraversion, agreeableness, conscientiousness, and openness were associated with more favorable outcomes. More specifically, agreeableness had positive associations with therapeutic alliance and conscientiousness was positively related to abstinence from substances suggesting these traits are likely a beneficial factor to consider at the outset of services. Personality traits also related to various outcomes differently based on moderators. For example, duration of treatment moderated links between traits and outcomes suggesting these effects are amplified over longer services. Overall results suggest that personality assessment can aid with case conceptualization by suggesting potential strengths as well as barriers to treatment.

Modeling and monitoring of treated wastewater based on water quality assurance parameters
Authors: Chemistry International CI , Hassen Elias Barsenga , Asmare Abraham M.
Published: April 2019

Recently, process control in wastewater treatment plants (WWTPs) is, mostly accomplished through examining the quality of the water effluent and adjusting the processes through the operator’s experience. This practice is inefficient, costly and slow in control response. A better control of WTPs can be achieved by developing a robust mathematical tool for performance prediction. Due to their high accuracy and quite promising application in the field of engineering, Artificial Neural Networks (ANNs) are attracting attention in the domain of WWTP predictive performance modeling. This work focuses on applying ANN with a feed-forward, back propagation learning paradigm to predict the effluent water quality of the Habesha brewery WTP. Data of influent and effluent water quality covering approximately an 11-month period (May 2016 to March 2017) were used to develop, calibrate and validate the models. The study proves that ANN can predict the effluent water quality parameters with a correlation coefficient (R) between the observed and predicted output values reaching up to 0.969. Model architecture of 3-21-3 for pH and TN, and 1-76-1 for COD were selected as optimum topologies for predicting the Habesha Brewery WTP performance. The linear correlation between predicted and target outputs for the optimal model architectures described above were 0.9201 and 0.9692, respectively.
Micelle-mediated extraction of cobalt and its spectrophotometric determination in rocks, soils, sediments and sea-bed polymetallic nodules
Authors: Int Chem , Tarafder Pranab Kumar
Published: April 2019

The surfactant sensitized bottle-green complex (1:2:1) formed of cobalt-thiocyanate-cetyltrimethylammonium bromide is suitably extracted into an organic solvent, ethylacetate, at a pH range, 6-8 and the absorption measurements were carried out at 630 nm (ƛmax). The Beer’s law is obeyed in the range from 0.05 to 10 μg per mL. The molar absorptivity and Sandell’s sensitivity of the present system were found to be 2.2 x 103 L.mol-1cm-1 and 0.026 μg cm-2, respectively. No other element forms complex of similar colour with thiocyanate at this pH range. The method was applied to a number of samples like rock, soil, sediment, polymetallic nodules etc., as well as Certified Reference Materials and the values were found highly satisfactory. The interference of Fe3+ which formed a reddish complex at acidic pH (<7) was eliminated when the complex was extracted at pH 8.0. The method is highly useful for the determination of cobalt in geological samples having its concentration from μg/mL to percentage level. As the method has been made highly selective for spectrophotometric determination of cobalt, it might be applied to almost all types of geological sample of diverse matrices.

Background: Although anxiety disorders can be treated very well with cognitive behavioral therapy, there are some patients who are not yet optimally benefiting from the therapy. In recent years, noninvasive brain stimulation methods have been studied as an add-on to psychotherapy.Objectives. Is there sufficient evidence for the use of noninvasive brain stimulation in the psychotherapy of anxiety disorders?Methods. A systematic review of previous therapy studies reviewing noninvasive brain stimulation in cognitive behavioral therapy of anxiety disorders.Results. In total, only 4 randomized controlled therapeutic trials could be found and were analyzed. These studies used repetitive transcranial magnetic stimulation (rTMS) shortly before or during exposure-based behavioral therapy. The use of active stimulation compared to placebo stimulation shows a positive additional effect in the medium range.Conclusions. Initial work shows an additional benefit of rTMS in cognitive behavioral therapy for the treatment of anxiety disorders. However, further studies must show which exact stimulation parameters are best suited to make a recommendation for the treatment practice
Has Stereotype Threat Dissipated Over Time? A Cross-Temporal Meta-Analysis

Stereotype threat – the social psychological threat that arises when one is in a situation or doing something for which a negative stereotype about one’s group applies (Steele, 1997) – has been broadly studied throughout the social sciences over the past two decades (for reviews, see Lewis & Sekaquaptewa, 2016; Steele, 2010). It is a theory that is purported to explain variance in disparities between those who are negatively stereotyped in certain domains (e.g. racial-ethnic minorities in academics, women in mathematics) and those who are not (e.g. White men in academics; Steele, 2010). Studies on stereotype threat have been conducted hundreds of times, and have yielded mixed findings. Early studies tended to yield positive findings (for meta-analytic review, see Nguyen & Ryan, 2008) whereas more recent reanalysis (Zigerell, 2017) and replication attempts (e.g., Finnigan & Corker, 2016) have failed to replicate findings. These conflicting accounts call into question the robustness of the paradigm, and raise two possibilities in our minds: either the strength of the evidence was weak to begin with, or something has changed over time to reduce the likelihood of finding stereotype threat effects. We test these possibilities in a pre-registered cross-temporal meta-analysis using multiple meta-analytic techniques.
What security features and crime prevention advice is communicated in consumer IoT device manuals and support pages?

Through the enhanced connectivity of physical devices, the Internet of Things (IoT) brings improved efficiency to the lives of consumers when on-the-go and in the home. However, it also introduces new potential security threats and risks. These include threats that range from the direct hacking of devicesthat could undermine the security, privacy and safety of its users, to the enslaving of IoT devices to commit cybercrime at scale, such as Denial of Service attacks. The IoT is recognised as being widely insecure, in large part, due to the lack of security features built into devices. Additionally, consumersdo not always actively use security features when available. More disconcerting is that we lack market surveillance on whether manufacturers ship products with good security features or how the importance of user-controlled security features is explained to IoT users. Our study seeks to address this gap. To do this, we compiled a database of 270 consumer IoT devices produced by 220 different manufacturers on sale at the time of the study. The user manuals and associated support pages for these devices were then analysed to provide a “consumer eye” view of the security features they provide and the cyber hygiene advice that is communicated to users. The security features identified were then mapped to the UK Government's Secure by Design Code of Practice for IoT devices to examine the extent to which devices currently on the market appear to conform to it. Our findings suggest that manufacturers provide too little publicly-available information about the security features of their devices which makes market surveillance challenging and provides consumers with little information about the security of devices prior to their purchase. On average, there was discussion of around four security features, with accountmanagement and software updates being the most frequently mentioned. Advice to consumers on cyber hygiene was also rarely provided. Finally, we found a lack of standardisation in the communication of security-related information for IoT devices among our sample. We argue for government intervention in this space to provide assurances around device security, whether this provided in a centralised ordecentralised manner.
Le travail clinique d’orientation humaniste en psycho-oncologie
Authors: Santarpia A.
Published: April 2019

Cet article illustre le travail clinique d’orientation humaniste en psycho-oncologie. Dans un premier temps, nous allons présenter les notions et les attitudes mobilisées par le clinicien dans l’écoute et la prise en charge de la souffrance du patient. La réintroduction d’un espace de réhumanisation, le travail sur la présence thérapeutique, le travail sur l’éprouvé corporel et sur les défenses psychocorporelles forment des axes particuliers à proposer au patient en fonction de sa demande. Dans un deuxième temps, le travail sur l’angoisse de mort à travers l’art sera abordé selon l’orientation humaniste (orientation transpersonnelle et existentielle) et selon une méthodologie d’analyse qualitative informatisée de la narration (logiciels Tropes et T-LAB). Ce « travail avec l’art » en psycho-oncologie sera illustré grâce à différents dispositifs (atelier de musique classique et de poésie) centrés sur les variations narratives des patients. Le « travail sur l’angoisse de mort » avec l’art peut non seulement éloigner le patient d’une narration somatique de la maladie (symptômes, plaintes, gênes et douleurs physiques), mais aussi générer des expériences corporelles agréables et une narration riche d’éléments symboliques et spirituels.
L’engagement dans la durée, quel chantier !

Comment rester vivant dans l’évolution d’un cancer au long cours, quand l’issue s’annonce fatale ? Comment vivre cela quand on est soignante, infirmière spécialisée en soins palliatifs et formatrice, et soudain propulsée comme malade atteinte d’un cancer génétique grave ? Je témoigne du chemin d’Eve avec sa psychothérapeute et de mon propre soutien de superviseuse à cette psychothérapeute. Quand les affects extrêmes affleurent, entre pulsions de vie et pulsions de mort, rage, impuissance et sursaut de vie, la contenance du contenant que représente le psychothérapeute est essentielle, en forme de poupées russes.
