Reducing the use of insecticides is an important issue for agriculture today. Sowing wildflower strips along field margins or within crops represents a promising tool to support natural enemy populations in agricultural landscapes and, thus, enhance conservation biological control. However, it is important to sow appropriate flower species that attract natural enemies efficiently. The presence of prey and hosts may also guide natural enemies to wildflower strips, potentially preventing them from migrating into adjacent crops. Here, we assessed how seven flower traits, along with the abundance of pollen beetles (Meligethes spp., Coleoptera: Nitidulidae) and true weevils (Ceutorhynchus spp., Coleoptera: Curculionidae), affect the density of parasitoids of these two coleopterans in wildflower strips sown in an oilseed rape field in Gembloux (Belgium). Only flower traits, not host (i.e. pollen beetles and true weevils) abundance, significantly affected the density of parasitoids. Flower colour, ultraviolet reflectance and nectar availability were the main drivers affecting parasitoids. These results demonstrate how parasitoids of oilseed rape pests react to flower cues under field conditions. Similar analyses on the pests and natural enemies of other crops are expected to help to develop perennial flower mixtures able to enhance biological control throughout a rotation system. [less ▲]

Introduction: The lateral elbow tendinopathy is a common injury in tennis players and physical workers. The Patient- Rated Tennis Elbow Evaluation (PRTEE) Questionnaire was specifically designed to measure pain and functional limitations in patients with lateral epicondylitis. The aims were to adapt the PRTEE questionnaire into French (PRTEE-F) and to evaluate the reliability and validity of this translated version of the questionnaire . Methods: The PRTEE was translated and cross-culturally adapted into French according to international guidelines. To assess the reliability and validity of the PRTEE-F, 115 participants were asked twice to fill in the PRTEE-F, and once the DASH and the SF-36. Internal consistency (using Cronbach’s alpha), test-retest reliability (using intraclass correlation coefficient (ICC), standard error of measurement and minimal detectable change), and convergent and divergent validity (using the Spearman’s correlation coefficients respectively with the DASH and with some subscales of the SF-36) were assessed. Results: The PRTEE was translated into French without any problems. PRTEE-F showed a good test-retest reliability for the overall score (ICC 0.86) and for each item (ICC 0.8-0.96) and a high internal consistency (Cronbach’s alpha 1⁄4 0.98). The correlation analyses revealed high correlation coefficients between PRTEE-F and DASH (convergent validity) and, as expected, a low or moderate correlation with the divergent subscales of the SF-36 (discriminant validity). There was no floor or ceiling effect. Discussion and Conclusions: The PRTEE questionnaire was successfully cross-culturally adapted into French. The PRTEE-F is reliable and valid for evaluating French-speaking patients with lateral elbow tendinopathy. [less ▲]

Background: The Victorian Institute of Sport Assessment-Patella (VISA-P), originally developed in English, assesses the severity of patellar tendinopathy symptoms. To date, no French version of the questionnaire exists. Objectives: The aim of our study was to translate the VISA-P into French and verify its psychometric properties. Methods: The translation and cultural adaptation were performed according to international recommendations in 6 steps: initial translation, translation merging, back translation to the original language, use of an expert committee to reach a prefinal version, test of the prefinal version, and expert committee appraisal of a final version. Afterward, the psychometric properties of the final French version (VISA-PF) were assessed in 92 subjects, divided into 3 groups: pathological subjects (n = 28), asymptomatic subjects (n = 22), and sports-risk subjects (n = 42). Results: All members of the expert committee agreed with the final version. On a scale ranging from 0 to 100, with 100 representing an asymptomatic subject, the average SD scores on the VISA-PF were 53 17 for the pathological group, 99 2 for the healthy group, and 86 14 for the sports-risk group. The test-retest reliability of the VISA-PF was excellent, with good internal consistency. Correlations between the VISA-PF and divergent validity of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) were low, and the correlation coefficient values measured between the VISA-PF scores and converged items of the SF-36 were higher. Conclusion: The VISA-PF is understandable, valid, and suitable for French-speaking patients with patellar tendinopathy. [less ▲]

Introduction: The Victorian Institute of Sport Assessment – Achilles tendinopathy questionnaire (VISA-A) evaluates the clinical severity of Achilles tendinopathy. The aim of this study was to translate the VISA-A into French and to study the reliability and validity of this French version, the VISA-AF.Method: The VISA-A was translated into French to produce the VISA-AF using a validated methodology in six steps. Thereafter, several psychometric properties of this French version such as test–retest reliability, internal consistency, construct validity and floor and ceiling effects were evaluated. Therefore, we recruited 116 subjects, distributed into 3 groups: pathological patients (n=31), at-risk athletes (n=63) and healthy people (n=22). Results: The final version of the VISA-AF was approved by an expert committee. On a scale ranging from 0 to 100, the average scores of the VISA-AF obtained were 59 (± 18) for the pathological group, 99 (± 1) for the healthy group and 94 (± 7) for the at-risk group. The VISA-AF shows excellent reliability, low correlations with the discriminant subscales of the SF-36 and moderate correlations with the convergent subscales of the SF-36. Conclusions: The French version of the VISA-A is equivalent to its original version and is a reliable and valid questionnaire for French- speaking patients with Achilles tendinopathy. [less ▲]

Introduction: The femoropatellar syndrom is one of the most common knee problem observable. The Kujala Anterior Knee Pain Scale (AKPS) is a questionnaire used to examine the subjective symptoms, such as the functional limitations and the anterior knee pain. Objective: The aims of the study were to translate and cross-culturally adapt the AKPS questionnaire into French and to evaluate the reliability and validity of this translated version of the questionnaire (AKPS- F). Patients : 101 patients with femoropatellar syndrom. Methods: The translation and the inter-cultural adaptation of the questionnaire has been adopted through the international recommendations highlighting 6 different steps : initial translation, translations synthesis, translation back to the original language, committee of experts, test of the pre-final version and the approval from the expert’s committee. Indeed the French version obtained, the participants have filled twice the AKPS with an interval of 7 days, and the Short Form Health in order to evaluate the psychometric properties (the internal coherence, the test-retest fidelity and the built validity). Results:The AKPS shows a high level of fidelity in the test-retest with a score of 0.97. The French translation also has a high internal coherence score with 0.87. The Kujula shows a great correlation with a part of the converging sub-scales from the SF36. There is a low/average correlation noticeable with the diverging sub-scales. There is no floor/ceiling effect. Discussion and conclusions: This study shows that AKPS-F is reliable and valid for the French patients suffering from a femoropatellar syndrom and can therefore be used. [less ▲]

The whitemouth croaker, Micropogonias furnieri, is a long-lived fish of high commercial importance in the Western Atlantic Ocean. Here, we used stable isotope ratios of carbon, sulfur and nitrogen and isotopic niche metrics (SIBER) to study feeding habits and track habitat use by whitemouth croakers in Guanabara Bay, an estuary in Rio de Janeiro state, Brazil. Our results highlighted size-related habitat segregation, with small juvenile (< 30 cm) fishes residing mostly inside estuaries, while large adult (> 60 cm) fishes feed mainly in Continental Shelf (CS) waters. Medium adult fishes (30-60 cm) appear to feed in multiple coastal and CS habitats. Moreover, their feeding ecology showed strong temporal differences, linked with seasonal and, to a lesser extent, inter-annual variation in oceanographic features of the ecosystem in which they live. Overall, these differences in ecological features suggest that (1) adult and juvenile whitemouth croakers should be treated as different components of the food web and (2) the conservation of these habitats should be prioritized to better manage and sustain the coastal fisheries in Guanabara Bay.

Introduction: Patellar tendinopathy (PT) is commonly observed in jumping sports. Even if its biomechanic is somewhat explored, no information is known about the muscle strength profile of these patients. Objective: To determine if there exists a specific profile of patients suffering from a PT. Patients: 43 patients (29+/-9.8 y.o) suffering from PT were recruited. To be eligible, the patients must not have suffered from any other traumatic or micro-traumatic injury than the PT on the pathologic limb. Methods: After a physical examination, the tendon damage was assessed by ultrasounds examination. The patients were then tested on an isokinetic dynamometer and the maximum torque (per unit of mass, MTm) developed by the quadriceps and the hamstrings were recorded for various angular velocities. After each test, a visual analog scale (VAS) was used to estimate the pain felt by the patients. Results: No significant correlation was found between the MTm and the demographic variables. The difference in MTm between the healthy and the pathological limbs was significant only at a rate of 60°/s, for both the quadriceps and the hamstrings. Lastly, the VAS score showed that the most intense pain was experienced after the eccentric test. Conclusions: There is no clear patient strength profile emerging from the isokinetic test. This stresses the importance for the clinicians to make testing and to apply a personalized treatment to each patient. Finally, the isokinetic eccentric testing of the quadriceps can be used to induce a mechanical stress on the tendon for a reliable pain assessment. [less ▲]

Introduction: Patellar Tendinopathies (PT) represent a very frequent disorder which incidence can reach 30-50% among jumping sports. This trouble is often rebel to classical treatment. Objective: To compare the efficacy of a single injection of RPR to a double infiltration of HA at one week interval. Patients/Methods: Thirty-three patients suffering from PT were enrolled into the study and split into two randomized groups . Eighteen patients (Group 1) have received one PRP injection and the other fifteen subjects (Group 2) received two HA infiltrations. Pain and functionality of the knee were evaluated before injection (T0), 6 weeks (T2) and 3 months (T3) after injections: pain with VAS and pressure algometer, algofunctional scores with IKDC and VISA-P questionnaires, ultrasound, isokinetic evaluation (quadriceps contractions : concentric 60°/sec (C60), concentric 240°/sec (C240), excentric 30°/sec (E30) and VAS during testing). Results: At baseline, difference existed only between groups for algometer, tendon thickness and axial hypoechoic area. In both groups, VAS, algometer, IKCD, VISA-P, VAS for isokinetic testing C60, C240 and E30 were significantly improved at T2 and T3 compared to T0. Comparison between the 2 groups showed no difference excepted for algometer, tendon thickness (T2, T3) and axial hypoechoic area (T2). Discussion and conclusions: There existed a similar improvement of the symptoms in both groups. PRP has already shown its efficacy in PT. HA should probably be a new therapeutic opportunity in this indication. Nevertheless, it should better, for further studies, to include a more homogeneous population and a longer follow-up period of time. [less ▲]

Organisms with complex life cycles are characterized by a metamorphosis that allows for a major habitat shift and the exploitation of alternative resources. However, metamorphosis can be bypassed in some species through a process called paedomorphosis, resulting in the retention of larval traits at the adult stage and is considered important at both micro- and macroevolutionary scales. In facultatively paedomorphic populations of newts, some individuals retain gills and a fully aquatic life at the adult stage (paedomorphs), while others undergo complete metamorphosis (metamorphs), allowing for a terrestrial life-stage. Because facultative paedomorphosis affects trophic structures and feeding mechanism of newts, one hypothesis is that it may be maintained as a trophic polymorphism, with the advantage to lessen intraspecific competition during the shared aquatic life-stage. Here, we tested this hypothesis combining stomach content data with stable isotope techniques, using carbon and nitrogen stable isotopes, in facultatively paedomorphic alpine newts Ichthyosaura alpestris. Both stomach content and stable isotope analyses showed that paedomorphs had smaller trophic niches and were more reliant on pelagic resources, while metamorphs relied more on littoral resources, corresponding to a polyphenism along the littoral-pelagic axis and the extension of the population's trophic niche to otherwise ‘underused’ pelagic resources by paedomorphs. Interestingly, stable isotopes revealed that the trophic polyphenism was less marked in males than in females and potentially linked to sexual activity. Although paedomorphosis and metamorphosis are primarily seen as results of tradeoffs between the advantages of using aquatic versus terrestrial habitats, this study provides evidence that additional forces, such as intraspecific trophic niche differences between morphs and trophic niche expansion, may play an important role in the persistence of this dimorphism in heterogeneous environments. Moreover, the different patterns found in males and females show the importance of considering sex to understand the evolutionary ecology of trophic polymorphisms. [less ▲]

How can new players seeking to serve nonstandard worker categories (such as project-based workers) establish themselves into labour markets that are highly institutionalized? This paper explores the case of SMart, a Belgian community-based labour market intermediary that successfully developed solutions to better represent the interests of project-based workers and secure their discontinuous careers. Using an organizational legitimacy approach, we find that labour market entry and growth involve different types of boundary-crossing when addressing the needs of workers that do not fit into established categories. However, to justify boundary-crossing, the new player must complement its pragmatic work on delivering new services and tools with conceptual (cognitive) and structural (moral) legitimation work.

My article looks at two recent Asian American texts written in the first-person plural – namely Julie Otsuka’s The Buddha in the Attic (2011) and Chang-rae Lee’s On Such a Full Sea (2014). My main goal is to show that the ambiguities and tensions generated by we narration in these two Asian American novels prove particularly apt when it comes to calling into questions essentialist views concerning the anatomy of community-building. But these two we texts are particularly interesting at a theoretical level, in that they help us challenge the orthodoxies of traditional narrative theory– among which Gérard Genette’s all-too-rigid distinction between the homo- and heterodiegetic levels in a text, or the generalized assumption, which has been notably challenged by Mieke Bal, that every act of story-telling is necessarily indebted to ‘a’ narrator, and a narrator of anthropomorphic standards at that.

The Büchi-Bruyère theorem states that a multidimensional set of non-negative integers is b-recognizable if and only if it is b-definable. This result is a powerful tool for showing that many properties of b-automatic sequences are decidable. Going a step further, first-order logic can be used to show that many enumeration problems of b-automatic sequences can be described by b-regular sequences. The latter sequences can be viewed as a generalization of b-automatic sequences to integer-valued sequences. These techniques were extended to two wider frameworks: U-recognizable multidimensional sets of non-negative integers and multidimensional beta-recognizable sets of reals. In the second case, real numbers are represented by infinite words, and hence, the notion of beta-recognizability is defined by means of Büchi automata. Again, logic-based characterizations of $U$-recognizable (resp. beta-recognizable) sets allows us to obtain various decidability results. The aim of this chapter is to present a survey of this very active research domain. [less ▲]
