Farmer adaptive behavior and risk management in EU agriculture

<p>Risk and risk management are essential elements of agriculture and affect the wellbeing of farm households. Farmers react to production, market and institutional risks and challenges by taking measures on or off the farm. Such risk management measures are often costly and have implications for up- and downstream industries as well as the environment. The risk exposure of European farms is increasing. For example, climate change will increase the frequency and magnitude of extreme weather events like droughts, heatwaves and heavy rainfalls that potentially have detrimental effects on agricultural production. Thus, the adaptive capacity and risk management options in European agriculture need to be improved. Policy shall support this process. Policies are needed to support a diversity of risk management solutions and not only focus on a few solutions. Strategies to cope with risk often go beyond the level of the individual farm. Cooperation, learning and sharing of risks play a vital role in European agriculture and shall be strengthened. Thus, coordinated policies targeting beyond the individual farm and considering all the stakeholders involved in the risk management strategies are needed to ensure their effective implementation. Moreover, policies need to facilitate to take full advantage of the rapid technological progress and improved data availability (e.g. based on satellite imagery) to develop a wider set of risk management strategies.</p>

Wrist-mounted IMU data towards the investigation of free-living human eating behavior - the Free-living Food Intake Cycle (FreeFIC) dataset

<p><strong>Introduction</strong></p> <p>The Free-living Food Intake Cycle (FreeFIC) dataset was created by the <a href="http://mug.ee.auth.gr">Multimedia Understanding Group</a> towards the investigation of <em>in-the-wild</em> eating behavior. This is achieved by recording the subjects&rsquo; meals as a small part part of their everyday life, unscripted, activities. The FreeFIC dataset contains the <span class="math-tex">\(3D\)</span> acceleration and orientation velocity signals (<span class="math-tex">\(6\)</span> DoF) from <span class="math-tex">\(22\)</span> in-the-wild sessions provided by <span class="math-tex">\(12\)</span> unique subjects. All sessions were recorded using a commercial smartwatch (<span class="math-tex">\(6\)</span> using the Huawei Watch 2&trade; and the MobVoi TicWatch&trade; for the rest) while the participants performed their everyday activities. In addition, FreeFIC also contains the start and end moments of each meal session as reported by the participants.</p> <p><strong>Description</strong></p> <p>FreeFIC includes <span class="math-tex">\(22\)</span> in-the-wild sessions that belong to <span class="math-tex">\(12\)</span> unique subjects. Participants were instructed to wear the smartwatch to the hand of their preference well ahead before any meal and continue to wear it throughout the day until the battery is depleted. In addition, we followed a self-report labeling model, meaning that the ground truth is provided from the participant by documenting the start and end moments of their meals to the best of their abilities as well as the hand they wear the smartwatch on. The total duration of the <span class="math-tex">\(22\)</span> recordings sums up to <span class="math-tex">\(112.71\)</span> hours, with a mean duration of <span class="math-tex">\(5.12\)</span> hours. Additional data statistics can be obtained by executing the provided python script <em>stats_dataset.py</em>. Furthermore, the accompanying python script <em>viz_dataset.py </em>will visualize the IMU signals and ground truth intervals for each of the recordings. Information on how to execute the Python scripts can be found below.</p> <pre><code># The script(s) and the pickle file must be located in the same directory. # Tested with Python 3.6.4 # Requirements: Numpy, Pickle and Matplotlib # Calculate and echo dataset statistics $ python stats_dataset.py # Visualize signals and ground truth $ python viz_dataset.py</code></pre> <p>FreeFIC is also tightly related to Food Intake Cycle (FIC), a dataset we created in order to investigate the <em>in-meal</em> eating behavior.

Wrist-mounted IMU data towards the investigation of in-meal human eating behavior - the Food Intake Cycle (FIC) dataset

<p><strong>Introduction</strong></p> <p>The Food Intake Cycle (FIC) dataset was created by the <a href="http://mug.ee.auth.gr">Multimedia Understanding Group</a> towards the investigation of <em>in-meal</em> eating behavior. The FIC dataset contains the triaxial acceleration and orientation velocity signals (<span class="math-tex">\(6\)</span> DoF) from <span class="math-tex">\(21\)</span> meal sessions provided by <span class="math-tex">\(12\)</span> unique subjects. All meals were recorded in the restaurant of Aristotle University of Thessaloniki using a commercial smartwatch, the Microsoft Band <span class="math-tex">\(2\)</span>&trade; for ten out of the twenty-one meals and the Sony Smartwatch <span class="math-tex">\(2\)</span>&trade; for the remaining meals. In addition, the start and end moments of each food intake cycle as well as of each micromovement are annotated throughout the FIC dataset.</p> <p><strong>Description</strong></p> <p>A total of <span class="math-tex">\(12\)</span> subjects were recorded while eating their launch at the university&rsquo;s cafeteria. The total duration of the <span class="math-tex">\(21\)</span> meals sums up to <span class="math-tex">\(246\)</span> minutes, with a mean duration of <span class="math-tex">\(11.7\)</span> minutes. Each participant was free to select the food of their preference, typically consisting of a starter soup, a salad, a main course and a desert. Prior to the recording, the participant was asked to wear the smartwatch to the hand that he typically uses in his everyday life to manipulate the fork and/or the spoon. A GoPro&trade; Hero <span class="math-tex">\(5\)</span> camera was already set at the table of the participant using a small, <span class="math-tex">\(23\)</span> cm in height, tripod facing the participant, including both the food tray and upper body part in it&rsquo;s field of view. The purpose of video recording was to obtain ground truth data by manually annotating the IMU sequences based on the video stream. Participants were also asked to perform a clapping hand movement both at the start and end of the meal, for synchronization purposes (as this movement is distinctive in the accelerometer signal). No other instructions were given to the participants. It should be noted that the FIC dataset does not contain instances related with liquid consumption or eating without the fork, knife and spoon (e.g. eating directly with hands). The accompanying python script <em>viz_dataset.py </em>will visualize the IMU signals and food intake cycle (i.e., bite) ground truth intervals for each of the recordings. Information on how to execute the Python scripts can be found below.</p> <pre><code class="language-python"># The script(s) and the pickle file must be located in the same directory. # Tested with Python 3.6.4 # Requirements: Numpy, Pickle and Matplotlib # Visualize signals and ground truth $ python viz_dataset.py</code></pre> <p>FIC is also tightly related to FreeFIC, a dataset we created in order to investigate the <em>in-the-wild </em>eating behavior.

Data from: Multimodal in situ datalogging quantifies inter-individual variation in thermal experience and persistent origin effects on gaping behavior among intertidal mussels (Mytilus californianus)

In complex habitats, environmental variation over small spatial scales can equal or exceed larger-scale gradients. This small-scale variation may allow motile organisms to mitigate stressful conditions by choosing benign microhabitats, whereas sessile organisms may rely on other behaviors to cope with environmental stresses in these variable environments. We developed a monitoring system to track body temperature, valve gaping behavior, and posture of individual mussels (Mytilus californianus) in field conditions in the rocky intertidal zone. Neighboring mussels' body temperatures varied by up to 14°C during low tides. Valve gaping during low tide and postural adjustments, which could theoretically lower body temperature, were not commonly observed. Rather, gaping behavior followed a tidal rhythm at a warm, high intertidal site; this rhythm shifted to a circadian period at a low intertidal site and for mussels continuously submerged in a tidepool. However, individuals within a site varied considerably in time spent gaping when submerged. This behavioral variation could be attributed in part to persistent effects of mussels' developmental environment. Mussels originating from a wave-protected, warm site gaped more widely, and they remained open for longer periods during high tide than mussels from a wave-exposed, cool site. Variation in behavior was modulated further by recent wave heights and body temperatures during the preceding low tide. These large ranges in body temperatures and durations of valve closure events - which coincide with anaerobic metabolism - support the conclusion that individuals experience "homogeneous" aggregations such as mussel beds in dramatically different fashion, ultimately contributing to physiological variation among neighbors.

Data from: Has gene expression neofunctionalization in the fire ant antennae contributed to queen discrimination behavior?

<p>Queen discrimination behavior in the fire ant <i>Solenopsis invicta</i> maintains its two types of societies: colonies with one (monogyne) or many (polygyne) queens, yet the underlying genetic mechanism is poorly understood. This behavior is controlled by two supergene alleles, <i>SB</i> and <i>Sb,</i> with ~600 genes. Polygyne workers, having either the <i>SB/SB</i> or <i>SB/Sb </i>genotype, accept additional <i>SB/Sb</i> queens into their colonies but kill <i>SB/SB</i> queens. In contrast, monogyne workers, all <i>SB/SB</i>, reject all additional queens regardless of genotype. Because the <i>SB</i> and <i>Sb</i> alleles have suppressed recombination, determining which genes within the supergene mediate this differential worker behavior is difficult. We hypothesized that the alternate worker genotypes sense queens differently because of the evolution of differential expression of key genes in their main sensory organ, the antennae. To identify such genes, we sequenced RNA from four replicates of pooled antennae from three classes of workers: monogyne <i>SB/SB</i>, polygyne <i>SB/SB,</i> and polygyne <i>SB/Sb</i>. We identified 81 differentially expressed protein-coding genes with 13 encoding potential chemical metabolism or perception proteins. We focused on the two odorant perception genes: an odorant receptor<i> SiOR463</i> and an odorant binding protein <i>Si</i><i>OBP12</i>. We found that <i>SiOR463</i> has been lost in the <i>Sb</i>-genome. In contrast, <i>SiOBP12</i> has an <i>Sb</i>-specific duplication, <i>SiOBP12b'</i>, which is expressed in the <i>SB/Sb</i> worker antennae, while both paralogs are expressed in the body. Comparisons with another fire ant species revealed that <i>SiOBP12b'</i> antennal expression is specific to <i>S. invicta</i> and suggests that queen discrimination may have evolved, in part, through expression neofunctionalization.</p>

A QUESTIONNAIRE FOR THE ASSESSMENT OF VIOLENT BEHAVIORS IN YOUNG COUPLES: THE ITALIAN VERSION OF DATING VIOLENCE QUESTIONNAIRE (DVQ)

<p>&nbsp;In the last years, intimate partner violence (IPV) became a relevant problem for community and for social life, particularly in young people. Its correct assessment and evaluation in the population is mandatory. Our objectives were: Confirm factor structure of Dating Violence Questionnaire (DVQ) and investigate its convergent and divergent validity. The DVQ along with other personality measures were filled by a sample of 418 university students (Females = 310) of average age of 23 y.o. (SD = 4.71). A subsample of participants (223 students) consented in being involved also in retest and filled also the Revised Eysenck Personality Questionnaire (short form) and a brief scale for describing the behavior of the (past) partner after the breaking of the relationship (BRS). The 8-factor structure, with respect to the two other competing models, reported better fit indexes and showed significant correlations with other personality measures. Personality traits, both Neuroticism and Psychoticism, correlated with Sexual Violence, while Detachment correlated only with Neuroticism and Coercion, Humiliation and Physical Violence correlated with only Psychoticism. Extraversion did not report significant relationships with any of the 8 DVQ factors. Also the predictive validity of DVQ was satisfactory with the partner violent reaction to the break of relationship predicted positively predicted by Coercion (b = 0.22) and by Humiliation (b = 0.20) and negatively by Emotional Punishment (b = -0.18). The present results indicate a good factor structure of the questionnaire, and interesting correlations with personality traits, allowing to identify psychological aspects with a predisposing role for anti-social aggressive behaviors. Further studies will be aimed at ascertaining other possible determinants of intimate partner violence and the weight of cultural aspects.</p>

On the Understandability of Semantic Constraints for Behavioral Software Architecture Compliance: A Controlled Experiment

<p>Software architecture compliance is concerned with the alignment of implementation with its desired architecture and detecting potential inconsistencies. The study is specifically concerned with behavioral architecture compliance. That is, the focus is on semantic alignment of implementation and architecture. In particular, the study evaluates three representative approaches for describing semantic constraints in terms of their understandability, namely natural language descriptions as used in many architecture documentations today, a structured language based on specification patterns that abstract underlying temporal logic formulas, and a structured cause-effect language that is based on Complex Event Processing. We conducted a controlled experiment with 190 participants using a simple randomized design with one alternative per experimental unit.</p>
