Abstract:

The patterns of spatial distribution and abundance were investigated for moth assemblages in the eucalypt woodlands of the Sydney Basin. A total of 228 species of Lepidoptera, distributed among 25 families, were recorded from three national parks located on the perimeter of the Sydney metropolitan region.From within the eucalypt woodland habitat of the Sydney Basin, the study investigated the spatial variation of night-flying Lepidoptera present at several different scales of observation, from the trap level through to across the landscape. Assemblages varied with spatial scale, with uniformity occurring across the landscape as a whole, however becoming patchy at finer spatial scales. Multivariate and turnover analysis indicated that although heterogeneity of abundance and richness may vary significantly depending on spatial scale, sites and national parks contained their own unique suite of species in comparison to one another.The structure of the assemblages of moths in the eucalypt woodlands of the Sydney Basin can vary, and is dependant on the level of spatial scale of observation. Further study needs to be conducted at a range of temporal scales to ascertain the presence of patterns in the Lepidoptera communities in the Sydney region in order to contribute to the development of suitable conservation strategies in the Sydney Basin.

Abstract:

Field experiments, with 125 watt Mercury-Vapour light-traps, are described in this Thesis. Catches of moths in water traps arranged in a circular mosaic pattern around the light-trap were distributed bivariate normal. Comparisons between the bivariate mean moth vector and the mean wind vector suggested that the wind vector determined the distribution of moths around the light-trap. In light winds, less than 1 metre/second, moths were randomly distributed around the trap. In stronger winds the direction of moth displacement from the trap was associated with the direction component of the mean wind velocity. A second experiment with light and water traps was used to estimate the effective light-trap radius. Two light-traps, surrounded by water traps, were separated by up to 25 metres on different evenings. When one light-trap was downwind of another the catch was significantly greater in the downwind trap. However, in crosswind conditions the two catches were similar. Bivariate methods were used to estimate that the effective trap radius was between 10 and 25 metres. A further experiment, using multivariate correlation and regression analysis, found that air temperature, windspeed and moonlight affected light-trap catches. An algorithm is described to enable the calculation of moonlight illuminance. Increased windspeed and increased moonlight illuminance tended to decrease the light-trap catch, however, increased air temperature was associated with an increase in light-trap catch. These effects varied depending on family and species. A final experiment used a remote sensing technique to estimate light-trap efficiency. A 10 cubic metre volume around the light-trap was observed using a video camera. Moth tracks recorded were classified into New Arrivals, Passers By and Local Flights. The number of these tracks was compared to the lighttrap catch so that efficiency estimates could be obtained. Results suggested that at ground level, 125 watt Mercury-Vapour light-traps are only 20 % efficient within this 10 cubic metre volume.

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico
O acompanhamento de saÃde da crianÃa nos primeiros anos de vida Ã essencial, uma vez que, alteraÃÃes no desenvolvimento neuromotor e comportamento do sono podem ser detectados pelos profissionais, que amenizam situaÃÃes de risco por meio de intervenÃÃes precoces. Com este estudo, objetivou-se avaliar o comportamento do sono e o desenvolvimento motor da crianÃa de 12 a 18 meses de idade, por meio de Infant Sleep Questionnaire (ISQ) - versÃo brasileira e Alberta Infant Motor Scale (AIMS); verificar a associaÃÃo das variÃveis sociodemogrÃficas e educacionais do cuidador e neonatais com os escores finais do Infant Sleep Questionnaire (ISQ) - versÃo brasileira e da AIMS. Este estudo Ã transversal e quantitativo, realizado no AmbulatÃrio de Pediatria de um hospital de referÃncia, em Fortaleza- CE, Brasil e em domicÃlio. Sua amostra Ã composta por 50 crianÃas e 50 cuidadores, no perÃodo de abril a outubro de 2014. A captaÃÃo dos participantes ocorreu com a busca direta em prontuÃrios/documentos ou contato com os pais e profissionais do serviÃo; aplicou-se, para isso, um instrumento de caracterizaÃÃo dos participantes, o ISQ - versÃo brasileira e a AIMS, aprovado pelo ComitÃ de Ãtica em Pesquisa sob o protocolo nÂ 422.103. Os cuidadores, em sua maioria, sÃo do sexo feminino (92%), com mÃdia de idade de 29 anos e maioria entre 25-34 anos (50%), uniÃo estÃvel (44%). Em relaÃÃo Ãs crianÃas, predominou o sexo feminino (58%), idade gestacional entre 35-41 semanas, nascidas a termo (84%), entre 12Â e 13Â mÃs de idade cronolÃgica (36%), mÃdia de 14,58 meses. Identificou-se, na classificaÃÃo do comportamento do sono das crianÃas, segundo os escores finais do ISQ - versÃo brasileira, a prevalÃncia de normalidade (escore<12) em 29 (58%) crianÃas. A maioria dos cuidadores (62%) apontou que suas crianÃas nÃo apresentavam problemas para dormir. Verificou-se associaÃÃo significante entre o escore final do ISQ - versÃo brasileira- e o critÃrio do avaliador (p=0,000). Em relaÃÃo Ã avaliaÃÃo do desenvolvimento motor, os escores finais da AIMS resultaram desempenho normal (70%), suspeito (20%) e atÃpico (10%). Identificou-se associaÃÃo estatisticamente significante entre escores finais do ISQ - versÃo brasileira com idade do cuidador (p=0,022) e pontuaÃÃo do Apgar no quinto minuto de vida (p=0,049); escores finais da AIMS com Idade Gestacional (p=0,013) e Idade cronolÃgica (p=0,001). Os escores finais da AIMS e os escores finais do ISQ - versÃo brasileira - nÃo apresentaram significÃncia estatÃstica (p=0,240). Concluiu-se que o comportamento do sono e desenvolvimento motor grosso na idade de 12 a 18 meses nÃo se apresentaram diretamente associados na maioria das variÃveis. PorÃm, ressalta-se que fatores parentais, ambientais e orgÃnicos sÃo determinantes ativos nesse processo, e essa relaÃÃo com o sono adequado permite a atividade cerebral atuar a favor do desenvolvimento.
The health monitoring of the child in the first years of life is essential, since alterations in the neuromotor development and sleep behavior can be detected by the professionals, who ameliorate risk situations through early interventions. The aim of this study was to evaluate the sleep behavior and motor development of the 12- to 18-month-old child using the Infant Sleep Questionnaire (ISQ) and the Alberta Infant Motor Scale (AIMS). To verify the association of the sociodemographic and educational variables of the caregiver and neonates with the final scores of the Infant Sleep Questionnaire (ISQ) - Brazilian version and AIMS. This cross-sectional and quantitative study was carried out at the Pediatric Outpatient Clinic of a reference hospital in Fortaleza, CE, Brazil, and at home. Its sample is made up of 50 children and 50 caregivers, from April to October 2014. Participants were approached by direct search of medical records or contact with parents and professionals of the service; For this purpose, an instrument for the characterization of the participants, ISQ - Brazilian version and AIMS, approved by the Research Ethics Committee under protocol No. 422.103. Most caregivers are female (92%), with a mean age of 29 years and the majority between 25-34 years (50%), stable union (44%). Among females, females predominated (58%), gestational age between 35-41 weeks, born full term (84%), between 12 and 13 months of chronological age (36%), mean of 14.58 Months. The prevalence of normality (score <12) in 29 (58%) children was determined according to the final ISQ (Brazilian version), in children's sleep behavior classification. Most caregivers (62%) reported that their children had no sleep problems. There was a significant association between the final ISQ score (Brazilian version) and the criterion of the evaluator (p = 0.000). Regarding the motor development evaluation, the AIMS final scores resulted in normal (70%), suspect (20%) and atypical (10%) performance. A statistically significant association between final ISQ scores - Brazilian version with caregiver's age (p = 0.022) and Apgar scores at the fifth minute of life (p = 0.049); Final AIMS scores with gestational age (p = 0.013) and chronological age (p = 0.001). The final AIMS scores and final ISQ scores (Brazilian version) did not present statistical significance (p = 0.240). It was concluded that sleep behavior and gross motor development at the age of 12 to 18 months were not directly associated with most variables. However, it is emphasized that parental, environmental and organic factors are active determinants in this process, and this relationship with adequate sleep allows the brain activity to act in favor of development.

Abstract:

Heliolithine moth larvae are serious agricultural pests causing hundreds of millions of dollars in agricultural damage annually. Mating disruption, a behavioral method of control of adult male sexual response to female pheromones, has been successfully administered in the field for many years, yet the underlying mechanisms that account for mating disruption are poorly understood. Habituation, a form of nonassociative learning, has been implicated as one possible mechanism that effects male moth behavior during the application of mating disruption strategies. To substantiate the claim that habituation can play a role in mating disruption, data were collected on five of habituation's classic characteristics: (1) The existence of a negatively accelerated relationship between trials and response strength; (2) Spontaneous recovery of response strength; (3) A long-term reduction in male moth pheromonal response strength; (4) More rapid reduction of response strength and greater spontaneous recovery of response with less intense stimuli; (5) Learning associated with a highly specific stimuli will not generalize to exceedingly dissimilar stimuli. Results of this study clearly indicate that all five characteristics related to habituation were present. Specifically, males, repeatedly exposed to pheromones of conspecifics, display a decrease in response strength. Response reduction and spontaneous recovery were both found to be greater with less complex stimuli. Long-term habituation was successfully demonstrated for up to 96 hours post habituation training. Most importantly, it was found that males, habituated to one blend, demonstrated little habituation when exposed to a second blend. Additionally, it was found that a substantial amount of individual differences in responsiveness to habituation training exists between males of this species. The findings of this study indicate two major points. First, habituation can be used as part of an effective integrated pest control strategy. However, because there is a substantial amount of individual differences in habituation susceptibility, some male moths may experience greater reproductive success. Further, because the males did not generalize habituation across the two stimuli presented in this study, there is concern that if all known pheromone components of this species are not used in field applications, males will habituate to the applied pheromone but not individual females.

Dissertation (PhD(Agric))--Stellenbosch University, 2003.
ENGLISH ABSTRACT: The codling moth, Cydia pomonella (L.) has been a major pest of pome fruits since before the turn of the last century. However, despite its high economic profile little is known about the bionomics and . behaviour of this pest in apple orchards in South Africa, information required for the development of a sustainable integrated management programme. In field trials there was contingency between the time of year and the upper and lower half of the tree. First generation moths laid significantly more eggs in the bottom half of the tree while second and third generation moths laid significantly more eggs in the top half of the tree. The preferred oviposition sites on Granny Smith (GS) and Golden Delicious (GD) cultivars, in order of preference, were leaves, fruit and wood. More eggs were laid on the fruit ofGS spurs (35.6 %) than on those ofGD spurs (10.7 %). On fruit spurs there was a significant increase in the number of eggs on GD leaves and GS fruit over the season, whereas the number of eggs on GS leaves and GD fruit remained constant. On branches there was an increase in the number of eggs on GD and GS leaves, but not on the fruit or wood. The preferred oviposition site on the fruit was the fovea of the stalk insertion and the rounded cheek area surrounding the fovea. The distribution within different fruit bearing classes (1 - 4 fruit per spur) was random only for one fruit per spur, while on the other spur classes clustering occurred. In laboratory studies of the embryonic and immature stages there was a linear relationship between rate of development and constant temperatures of 15, 17,20,25 and 30·C ± l·C. The lower threshold temperatures for embryonic, larval and pupal development were 11.1, 7.9, 9.9°C respectively. The degree-days required to complete embryonic, larval and pupal development were 80.5, 345, and 279 respectively. The response of the different stages to constant temperatures was similar to that under fluctuating temperatures. At temperatures below 16°C or abouve 27°C moths did not mate and few eggs were laid. Moth longevity decreased with increasing temperature. There was seasonal variation in longevity and oviposition at constant and fluctuating temperatures. Summer adults produced significantly more eggs than spring adults at constant temperatures. At a constant temperature of2S·C and fluctuating temperatures there were five distinct larval instars. The similarity between the mean head capsule width and ranges for each instar reared on fruit of different stages of development at fluctuating temperatures indicates that fruit development and temperature have little influence on mean head capsule width. From sleeve-cage studies in the orchard there was no significant difference in the fecundity of spring and summer moths. In the beginning of October spring moths produced significantly fewer eggs than in November. Egg mortality increased from 8.2 %in spring to 21.2 %in summer. Failure of 1st instar larvae to penetrate the fruit ranged from 4.9 % to 19.5 %, while mortality oflarvae from egg hatch to emergence from the fruit ranged from 29.7 % to 42.9 %. Mortality of 5th instar larvae after emerging from the apples ranged from 0 % to 8.7 % and pupal mortality from 0 % to 3.5 %. On large 27-year old trees more overwintering larvaewere found on Golden Delicious (13.9) than on Granny Smith trees (5.7), with over 70 % oflarvae being found in pruning wounds on both cultivars. On small 7-year old Golden Delicious and Granny Smith trees the mean number oflarvae was 0.5 and 2.0 per tree. A combined mating disruption and insecticide control programme reduced codling moth resistant populations to levels requiring a minimum to no insecticide intervention for several seasons. The efficacy of a pheromone based strategy, number of pheromone treatments, number of dispenserslha and level of insecticide intervention required are strongly influenced by prevailing weather conditions. Fruit infestation in orchards under a mating disruption programme and under an insecticide programme were greater along the borders compared to the interior. The presence of horticultural mineral oil on the leaves and branches did not have a detrimental effect on oviposition nor was there any significant ovicidal effect. A significant ovicidal effect was obtained when applied after oviposition. In field trials, insecticides with lower levels of efficacy than the primary insecticide, azinphos-methyl, provided acceptable control when successfully incorporated into a spray programme which followed a policy of alternation of insecticides across generations. The least variation in the number of degree-days between biofix and first egg hatch of the spring flight was when the second trap catch (Biofix 2) was used as the biofix. A biofix based on the first evening when the temperature reached or exceeded 1TC at 18:00 after first trap catch also showed less variation than when the biofix was based on first trap catch. The mean number of degree-days accumulated between Biofix 2 and first egg hatch was found to be 139.1 ° D. The number of degreedays between the first and second flight biofixes varied between 531.2 and 488.87°D with a mean of 508.1°D.
AFRIKAANSE OPSOMMING: Kodlingmot (Cydia pomonella) is reeds sedert die vorige eeu 'n sleutelplaag van kemvrugte. Ten spyte van die hoë ekonomiese profiel, is daar min kennis betreffende die bionomie en gedrag van hierdie plaag in appelboorde in Suid-Afrika. Hierdie inligting is noodsaaklik vir die ontwikkeling van 'n volhoubare geïntegreerde bestuursprogram. Tydens veldproewe is 'n korrelasie tussen die tyd van die jaar en eierlegging in die boonste of onderste helfte van bome gevind. Eerste-generasie motte het betekenisvol meer eiers in die onderste helfte van die bome gelê, terwyl tweede- en derde-generasie motte meer eiers in die boonste helfte van die bome gelê het. In toenemende volgorde was die voorkeur eierleggingsposisies op Granny Smith (GS) en Golden Delicious (GD) appels die blare, vrugte en hout. Meer eiers is op vrugte van GS spore (35.6%) as op dié van GD spore (10.7%) gelê. Op vrugspore was daar 'n betekenisvolle toename in aantal eiers op GD blare en GS vrugte deur die seisoen, terwyl die getal eiers op GS blare en GD vrugte konstant gebly het. Op takke was daar 'n toename in aantal eiers op GD en GS blare, maar nie op vrugte of hout nie. Die voorkeur eierleggingsposisie op vrugte was die fovea van die steelaanhegting en die wang rondom die fovea. Die verspreiding tussen verskillende vrugdraende klasse (1 - 4 vrugte per spoor) was slegs in die een-Vrug-per-spoorklas ewekansig, terwyl daar in die ander spoorklasse groepering voorgekom het. In laboratoriumstudies van embrioniese en onvolwasse stadia is 'n lineêre verband tussen ontwikkelingskoers en konstante temperature van 15, 17,20,25 en 30°C±I°C gevind. Die onderste drempel-temperature vir embrioniese, larwale en papie-ontwikkeling was onderskeidelik II. 1°C, 7.f?C en 9.9°C. Graaddae benodig vir voltooiing van embrioniese, larwale en papie-ontwikkeling was onderskeidelik 80.5,345 en 279. Die respons van verskillende stadia by konstante temperature het ooreengestem met hul respons onder wisselende temperature. Motte het nie gepaar nie en min eiers is gelê by temperature onder 16°C of bo 27°C. Die lewensverwagting van motte het afgeneem met toename in temperatuur. Seisoenale variasie in . lewensverwagting en eierlegging het voorgekom by konstante sowel as wisselende temperature. By konstante temperature het somer-volwassenes betekenisvol meer eiers as lente-volwassenes geproduseer. By 'n konstante temperatuur van 25°C, sowel as by wisselende temperature, het vyf duidelik onderskeibare larwale instars voorgekom. Die ooreenkoms tussen die gemiddelde kopkapsulewydte en wydte-reeks vir elke instar wat op vrugte van verskillende stadiums van ontwikkeling by wisselende temperature geteel is, dui daarop dat vrugontwikkeling en temperatuur weinig invloed op gemiddelde kopkapsule-wydte het. Tydens mou-hok studies in die boord is geen betekenisvolle verskil in die fekunditeit van lente- en somer-motte waargeneem nie. Vroeg in Oktober het lente-motte betekenisvol meer eiers as in November geproduseer. Eiermortaliteit het van 8.2% in die lente tot 21.2% in die somer toegeneem. Faling van 1ste instar larwes om vrugte te penetreer het van 4.9% tot 19.5% gewissel, terwyl mortaliteit van larwes vanaf uitbroei tot uitkoms uit die vrug van 29.7% tot 42.9% gewissel het. Mortaliteit van Sde instar larwes na uitkoms uit die vrug het van 0% tot 8.7% gewissel, en papie-mortaliteit van 0% tot 3.5%. Op groot, 27-jaar oue bome is meer oorwinterende larwes op Golden Delicious (13.9) as op Granny Smith (5.7) gevind, en meer as 70% van die larwes op beide kultivars is op snoeiwonde gevind. Op klein, 7-jaar oue bome was die gemiddelde aantallarwes op Golden Delicious en Granny Smithbome 0.5 en 2.0 onderskeidelik. 'n Gekombineerde paringsontwrigting- en insekdoder beheerprogram het weerstandbiedende kodlingmot-populasies verminder tot 'n vlak waar minimum tot geen insekdoder-toedienings vir verskeie seisoene gemaak is. Die effektiwiteit van 'n feromoon-gebaseerde strategie, aantal feromoonbehandelings, aantal vrystellers/ha en vlak van insekdoder-toediening word sterk deur heersende weersomstandighede beïnvloed. Die rande het hoër vruginfestasie as die middel getoon in boorde onder paringsontwrigting sowel as boorde onder insekdoder-programme. Die teenwoordigheid van minerale olie op blare en takke het geen nadelige effek op eierlegging gehad nie en dit het geen betekenisvolle eierdodende effek gehad nie. Indien die olie ná eierlegging toegedien is, is daar wel 'n betekenisvolle eierdodende effek waargeneem. Tydens veldproewe het insekdoders met laer effektiwiteit as die primêre insekdoder, azinfos-metiel, aanvaarbare beheer verskaf indien dit suksesvol geïnkorporeer is in 'n spuitprogram deur 'n beleid van afwisseling van insekdoders oor generasies. Die kleinste variasie tussen die aantal graaddae tussen biofix en eerste uitbroei van eiers is gevind indien die tweede lokvalvangs as biofix gebruik is. 'n Biofix gebaseer op die eerste aand na die eerste lokval vangste wat die temperatuur 17°Cofhoër was teen 18:00, het ook 'n kleiner variasie getoon as die eerste lokvalvangs. Die aantal graaddae tussen die tweede en derde vlug biofix het tussen 531.2 en 488.87°D gewissel, met 'n gemiddelde van 508.1°D.

Abstract:

Parents are the most affective human environmental resources to children. Although the influences from parents continue even after parents passed away, very young children (up to age 3) get the biggest impact from their parents. According to children's independency to parents, parents ' psychological well-being determines children's emotional-social development. However, in parenting stress, chi ldren also have their own influence to parents in the family context. Regarding parenting stress, many studies have been dedicated to defining the occurrence, co-occurrence, and predictors of parenting stress of parents in various conditions. This longitudinal research conducted from surveys with 20 I Early Head Start families reexamines the stressors and tests measures to find the most effective identifying variables. Also, the aim of this study is whether fathers' and mothers' parenting stress is different or similar with a child at the ages of I 0 months and 36 months. From the results of this study, stressors, parenting stress, and child attachment were related and influenced each other. Because the amount of fathers' and mothers' parenting stress was different, and because parenting stress was affected by different stressors according to parents' gender, the Early Head Start program should consider the differences in parenting stress due to the gender of parents. Additionally, as the children grew, the relations among stressors, parenting stress, and child attachment changed. Children 's development can change all circumstances including parents' physical and psychosocial well-being. Further studies need to identify additional sources of parenting stress and the impact of intervention programs on the stressors affecting families raising young children. Also, the Early Head Start program had an effect on the context of parenting stress, so results may have implications for staff of the program.

These effects varied depending on family and species. A final experiment used a remote sensing technique to estimate light-trap efficiency. A 10 cubic metre volume around the light-trap was observed using a video camera. Moth tracks recorded were classified into New Arrivals, Passers By and Local Flights. The number of these tracks was compared to the lighttrap catch so that efficiency estimates could be obtained. Results suggested that at ground level, 125 watt Mercury-Vapour light-traps are only 20 % efficient within this 10 cubic metre volume.

Abstract:

The roles of ocelli and octopamine in regulating the onset, intensity, and duration of cabbage looper moth flight activity were examined. This was achieved by studying the flight activity of control, sham, and anocellate moths with and without octopamine treatment. Sham and anocellate moths were produced by cauterization in last-instar larvae, of ocellar primordial cells for anocellate moths, and of non-involved cells for sham moths. Flight activity of moths was monitored by a computerized actograph under normal light (LD) conditions, under advanced-sunset, and under constant dark (DD) conditions to determine the effect of ocelli on flight activity. The role of octopamine was investigated by treating the three groups of moths topically with octopamine dissolved in dimethyl sulfoxide (DMSO) and with DMSO alone, and comparing flight activity before and after treatment. Results support a combined role for ocelli and the compound eyes in determining flight initiation times, and a role for ocelli in determining flight intensity. These roles were more pronounced in males than in females. It was found that the cauterization operation itself decreases flight activity in sham moths. No evidence was found that supports the existence of an octopamine effect on flight activity in any of the groups of moths when octopamine is topically applied.

Abstract:

The Moth Detroit StorySLAM is one of many storytelling events staged in urban bar environments. Unlike the increasingly aged audiences attending the National Storytelling Festival and similar story festivals, the Detroit StorySLAM consistently yields at capacity crowds of college students and young professionals. Participants were informally interviewed during the September, October, and November slams of 2010 and the January 2011 slam. In addition to conducting these interviews, the researcher was a participant observer—throwing her name into the hat and being twice called to the stage. Data are presented as a thick description organized according to Richard Bauman's 6 situational factors of the performance event. Until now questions about the nature and meaning of storytelling have been largely considered from the storyteller's perspective. By redirecting those questions to the listeners, this study reveals the ethos of hundreds of story enthusiasts—an undisputed admiration for the revelation of authentic, individual truths.

It is conThe oriental fruit moth, Grapholita molesta, is one of the main pests of peach trees worldwide. Plant volatiles are a promising technique to attract G. molesta under mating disruption conditions. In my thesis I have characterized the response of olfactory receptor neurons (ORN) to pheromone and plant odors by means of single-sensillum electrophisiology. I then used this information to determine that a previously reported pheromone-plant synergism does not result from pheromone-plant interactions at the ORN level. I have compared several plant volatile blends previously tested in Australia and China, and have found that none of them attracted moths in the field, but they synergized pheromone responses in the laboratory. Finally, I investigated the role of plant blends and alcohols on the response to unnatural pheromone blend ratios or overdosed pheromone concentrations. With these studies we hopefully advanced on basic and applied aspects of the olfactory neuroethology of this species.

Abstract:

Artificial light at night (ALAN) is becoming a greater threat to nocturnal species. Aside from the overall increase in light output, replacing outdated monochromatic street lighting with light-emitting diode (LED) lights with a broad emission spectrum could raise this issue more. However, studies evaluating the effect of artificial lights on nocturnal species, such as moths, are scarce. This study examines any variations in moth attraction as well as any other sex-based behavioural differences (mating behaviour – wing fanning, trajectory-circular movement, overall movement time) between male and female moths in the presence of warm-white light. This study used warm-white light LED (2718 K) and Galleria mellonella moth, reared in the lab and completed the experiment under standardised conditions in an enclosed setting. I found the male moths (100%) were significantly (p = 0.024) attracted to warm-white light LED compare to female moths (37%). While other behaviours such as wing fanning, circular movement, overall moving time, and favoured light illuminance for rest weren't significantly different (p > 0.05). In the future, it will be important to investigate the effects of warm-white light LED with different lower CCT (< 2718K) on moths, as well as the sex differences in their behaviour both in a controlled and an open environment. This will help authorities to decide on outdoor lighting systems in different countries and continents.

Full text

Abstract:

Nitric oxide (NO) is a gaseous, unconventional chemical messenger suggested to play a fundamental role in olfaction. This thesis focuses on the role of NO in a primary olfactory center, the antennal lobe (AL) of the moth, Manduca sexta (M. sexta), to understand how NO affects olfactory-guided behavior. Studies in M. sexta report that NO is produced upon odor stimulation and has profound effects at the physiological level, but little is known about its significance to behavior. The central hypothesis examined in this thesis is that NO functions as a neuromodulator of olfactory-guided behavior in a circadian fashion. This hypothesis is examined in the following three studies: The first study questions whether basal levels of NO fluctuate with the light cycle. M. sexta are nocturnal animals that actively engage in odor-seeking behaviors at night. Using an NO sensor, NO concentrations were measured in the AL, optic lobe, and the remainder of the brain during subjective day and subjective night. NO concentrations are higher in the AL and optic lobes at night, suggesting that NO is likely involved in olfactory-guided behavior. The second inquiry focuses on developing a technique to manipulate NO levels in the AL and whether a specific behavior is affected. Using the proboscis extension reflex, olfactory conditioning is used to ask three questions: (1) does NO affect odor detection, (2) does NO affect discrimination between odorants, and (3) does NO affect learning and memory? Results indicate that NO affects short-term memory but does not affect odor detection, or discrimination between dissimilar odorants. The third inquiry examines the role of NO in memory and circadian time. It asks: (1) is there an optimal time of day for learning and memory, and (2) does the role of NO in memory change depending on the time of olfactory conditioning? Results indicate that NO in memory is modulated by circadian time. Taken together, these results suggest a unique functional role for NO in olfactory-guided behavior with two main conclusions: (1) NO modulates short-term memory in the AL, and (2) NO may be important for the circadian regulation of memory.

Abstract:

Introduction: Successful storage of memory can be divided into three fundamental processes: encoding, consolidation and retrieval. During encoding, information is acquired e.g. in a learning session of an experiment. New mnemonic traces are formed in the brain. When the information needs to be remembered e.g. at the retrieval session of an experiment, memory needs to be recovered. Since encoding does not lead to instantaneous permanent storage of the learned material, a form of memory stabilization is necessary. A person’s freshly acquired memory is initially fragile until the memory trace is reinforced through a process of consolidation. While learning and retrieval must occur during wakefulness, memory consolidation can occur during sleep. One question that is still under debate in sleep literature is whether a period of sleep, in comparison to wakefulness, significantly and persistently benefits the consolidation of recently and explicitly acquired declarative information (such that memory retrieval after a period of sleep is significantly better than retrieval after a period of wakefulness). A further problem regarding the benefit of sleep for memory is the discrepancy between functional and behavioral findings: Sleep associated changes are possibly a covert process and changes on the anatomical level are not necessarily congruent with behavioral results. Another question concerns memory consolidation in the long run. In humans, the medial temporal lobe, especially the hippocampus, is an important brain structure involved in declarative memory retrieval. Through the process of consolidation, declarative memory has been found to become independent of the hippocampus over time. Yet, human imaging studies investigating memory retrieval for a longer period of time (several months) are scarce. Another gap of knowledge lies in the role of the hippocampus. Several different hypotheses about its role exist: The multiple trace theory, established by Nadel and Moscovitch (1997), states that personally experienced episodes stay hippocampus dependent, whereas semanticized memories become independent over time. O’Keefe et al. (1978) proposed that the hippocampus is permanently accessed for spatial memory retrieval. According to Eichenbaum (2000), the hippocampus binds new information coupled with an episode into a network of existing memory traces. This thesis focuses on long-term memory. The major focus lies on declarative memory, whereas the minor focus lies on non-declarative memory. All five studies of this thesis investigate declarative memory and the last study (study 5) additionally investigates non-declarative memory. Study 1: Objective: To investigate the relation between episodic (declarative) memory and sleep versus sleep deprivation on the functional and behavioral level. The aim is to do the investigation on a time scale of 2 ½ months. Methods: The analysis was based on a between-group (factor: sleep / wake), within-subject (factor: autobiographical task / spatial task) design. Each subject learned two episodic memory tasks (word associations): an autobiographical task and a spatial task. Brain activity (using a 3T MRT) and behavioral performances were measured at 3 times: 1) Immediately after learning; 2) after a night of sleep/wake and two recovery nights of sleep; 3) 2 ½ months after learning. Results: No sleep related changes in hippocampal activation could be concluded from the neuroimaging results. Supporting this, behavioral results (free recall) showed no difference between sleep and sleep deprivation groups. Recall results showed no difference between the sleep group and the sleep deprivation group. Study 2: Presuming that sleep supports hippocampus dependent declarative memory, but given the results of study 1, it was important to investigate the role of the hippocampus. Objective: This study focused on the role of the hippocampus in declarative memory retrieval, given the different hypotheses (mentioned above) about its role. Methods: Using a between-group design, hippocampal involvement during free recall at an early stage after encoding was compared between sequential, spatial and autobiographical learning strategies. (Study 2 was not a sleep-study). Free recall performance of concrete nouns was measured on the functional as well as behavioral level. Results: Not all episodic memory traces depended equally on the hippocampus when information was retrieved in free recall: Whereas recall of autobiographical memory relied on the hippocampus after consolidation, recall of spatially and sequentially associated information did not. Functional conjunction analyses showed that brain areas mutually involved in all tasks tested, were: the precuneus (medial parietal cortex), medial occipital gyrus and superior parietal lobe (SPL). Studies 3 – 5: The specific mechanisms underlying the process of memory consolidation are still not clarified. It has been suggested that a positive effect of sleep on memory occurs when a sensitive set of requirements is met, although to date, pinpointing the exact requirements has not been possible from sleep literature. Study 3: Objective: The question to be answered was: Is the type of retrieval, that is, cued recall or recognition, crucial for an effect of sleep on declarative memory? Methods: The following parameters were applied: i) Cued recall and recognition as the type of retrieval test; ii) Circadian rhythm: Learning either in the morning or in the evening; iii) The retention period between learning and the post-conditional test was kept constant at 12 hours; iv) Interference learning was used; v) The learning material was restricted to non-sense syllables. Results: A beneficial effect of sleep on memory retrieval 12 hours after learning non-sense syllables occurred only when syllables were tested via cued recall. However, results were influenced by circadian rhythm effects with better test scores in the morning than in the evening. Study 4: Objective: Same as in study 3, but controlling for the circadian rhythm effects by using nap sleep instead of nocturnal sleep. Methods: Circadian rhythm effects were controlled by choosing a 60 minute nap sleep paradigm, in which encoding and retrieval both took place at the same time of day (in the afternoon), for both the sleep and wake conditions. The two types of retrieval in relation to nap sleep and wakefulness were examined: cued recall and recognition. The following parameters were applied: i) Cued recall and recognition for the type of retrieval test; ii) Circadian rhythm: Learning in the afternoon; iii) The retention period between learning and the post-conditional test was kept constant at three hours (including a 60 minute nap or time spent awake); iv) Interference learning was used; v) The learning material consisted of concrete German nouns. Results: subjects did not perform significantly better after a period of napping compared to a period of wakefulness, neither for words tested via cued recall nor words tested via recognition. A sleep benefit on the behavioral level did not show to be specific to the type of retrieval test. Study 5: Objective: To examine whether a sleep benefit occurs between a critical period of 12 to 144 hours post learning. In addition to declarative memory, the relation between sleep and procedural memory is tested, using a motor sequence (finger tapping) task. Methods: Subjects learned a procedural and a declarative task. The following parameters were applied: i) Free recall for the declarative and procedural retrieval tests; ii) In contrast to the other studies, total sleep deprivation and daytime wakefulness were used as wake condition iii) The retention period between learning and testing was 12, 72 or 144 hours (3 groups); iv) Interference learning was not used for the declarative task (a main and new motor sequence task were learned); v) The learning material was restricted to non-sense syllables. Results: No beneficial post-learning effect of sleep could be detected in the declarative and procedural tasks over the retention interval of up to six days. Results of study 5 demonstrated that sleep after learning did not lead to better performance of motor skills than wakefulness after learning. Conclusion: From the results of the five studies of this thesis, it can be concluded that declarative and procedural memories are consolidated equally well over a period of wakefulness compared to a period of sleep. The type of retrieval, circadian rhythm, retention period, interference, and the type of material might all contribute to a set of variables influencing the benefit of sleep on memory. It can also be assumed that the human brain is capable of compensating a night of sleep deprivation without significant behavioral deficits during retrieval of verbal declarative and motor skill tasks, whether memory is tested shortly after encoding (a few hours), after days or after months.

Abstract:

Curative colorectal cancer (CRC) treatment affords longer survival but its effects can be debilitating. Current evidence focuses on long-term outcomes of treatment, which leaves a knowledge gap on how patients fare within the acute timeframe (within six months of treatment). A systematic review of the literature highlighted a research gap, therefore a prospective observational study was conducted to understand the acute impact of curative CRC treatment on patients' physical activity, sedentary behaviour, functional status, and quality of life (QoL). Study results suggest that the acute timeframe provides an opportunity to improve patients' physical activity, sedentary behaviour, functional status, and QoL.

Abstract:

Childhood undernutrition remains a public health problem in slums in Nairobi, yet little is known about current childcare practices, particularly child eating and maternal feeding behavior and their impact on child growth. Treatment options for malnutrition in this setting involve the use of sweet, high energy ready to use foods (RUF), which have the potential to displace home foods, but few studies have assessed this. This thesis therefore aimed to quantify high-risk caring practices in children aged 6-24 months and how these vary with nutrition status. The effects of RUF on meal frequency and eating and feeding behavior were also assessed. The programme of research was underpinned by the following research questions: • What are the commonest modifiable risk factors for undernutrition found in children and how does this pattern vary with nutrition status? • Do ready to use foods displace complementary foods in moderately undernourished children? • Do ready to use foods affect eating and feeding behaviour? Preliminary studies were carried out to test the feasibility of using observations to assess childcare practices. Caregivers of children aged between 6 and 24 months were recruited in Wagha town, a semi urban area in Lahore, Pakistan and in selected slums in Nairobi, Kenya. A structured observation guide was used to collect information on caregiver child interactions during mid-morning meals in Pakistan and lunch time meals in Kenya. A description of childcare practices in the household, specifically dietary practices, feeding behaviour and hygiene practices were assessed by asking the following questions: Who feeds the child? How is the child fed? What is the child fed and how often? What are the hygiene practices of caregivers? Thirty meal observations, 11 in Pakistan and 19 in Kenya, were carried out in homes, while 11 meals were observed in day-care centres in Nairobi. Eating and feeding behaviours varied between cultures. Compared to caregivers in Kenya, caregivers in Pakistan offered more encouragement during meals. In Kenya, encouragement was mainly in response to food refusal and undernourished children were more likely to show aversive eating behaviour. Caregivers would respond to this behaviour by either restraining the child or simply leaving them alone. In day-care centres, laissez faire feeding was common as children were left to feed themselves with little or no assistance. Poor hygiene practices were also common, especially in Kenya where caregivers did not wash their hands before feeding their children. Meal observations were not representative as only one meal could be observed and they were also not practical because of insecurity in the slums. Based on these findings, a cross sectional study carried out in seven health facilities was designed. Caregivers of children aged 6-24 months were recruited from health facilities in two stages. In the first stage, undernourished children (weight for age or weight for length below - 2 Z scores or length for age below -3 Z scores) were quota sampled either from outpatient therapeutic or supplementary feeding programs based on severity and supplementation status between February and August 2015. Undernourished children were recruited from well-baby clinics during growth monitoring. Between July and August 2016 healthy children (weight for age above-2 Z scores) were also recruited from well-baby clinics at the same health facilities. For both groups, child anthropometric measurements were taken and information on sociodemographic, hygiene breastfeeding frequency, meal frequency, dietary diversity, child eating and caregiver feeding behaviour collected using a structured interview guide. Among children receiving ready to use foods, information on child interest in food, food refusal and caregiver force-feeding was also collected for both family meals and ready to use food meals. We recruited 415 children (54.5% female), over half (58.6%) of whom were undernourished. Caregivers and their children came from disadvantaged backgrounds characterized by low parental education. They also lacked access to basic hygiene and sanitation facilities. There was no association between nutrition status and hygiene as nearly all children came from households that lacked piped water (83.6%) and shared toilets (82.9%). Compared to healthy children, undernourished children were more likely not to be breastfeeding (undernourished 11.5%; healthy 5.2% P=0.002) and to receive plated meals at a low frequency (undernourished 12.2%; healthy 26.2% P=0.002). Diets offered were mainly carbohydrate based and there was no association between dietary diversity and nutrition status. Close to one third of children showed low interest in food 25.8% (107) and high food refusal 22.5% (93). Force-feeding was also relatively common 38.5% (155). Compared to healthy children, undernourished children were more likely to show low interest in food (undernourished 34.2%; healthy 14.0% P < 0.001) and high food refusal (undernourished 30.9%; healthy 10.5% P < 0.001); and their mothers were more likely to be anxious about feeding them (undernourished 20.6%; healthy 6.4% P < 0.001). Within the undernourished group, 49.4% had either low interest in food or high food refusal or both. Force-feeding was common in both groups, with a non-significant trend towards more force-feeding in the undernourished infants (undernourished 41.4%; healthy 34.5% P=0.087). Children were more likely to be force-fed if they had low interest in food (odds ratio[95% CI] 3.72 [1.93 to 7.15] P < 0.001) or high food refusal (4.83[2.38 to 9.78] P < 0.001), after controlling for maternal anxiety and child nutrition status. Children appeared to prefer RUF to home foods which is good for treatment compliance, but it may have a negative impact on intake of home foods. Although a single sachet of RUF appeared not to displace family meals in moderately undernourished children, actual energy intake was not measured in this study and these findings are therefore inconclusive. Children in slum areas in Nairobi are exposed to many risk factors which puts them at risk of infection and undernutrition and provision of ready to use foods as a treatment option does not address the underlying problem. There is therefore a need for poverty alleviation strategies which will lead to improved access to hygiene facilities and better environmental conditions. Measures to improve access and utilization of safe nutritious foods as well as mother-child interactions during meals are also required. A better understanding of child care practices and underlying factors that influence them is also required for the design of effective and sustainable interventions in this setting.

Abstract:

Semiochemicals are chemicals used to communicate. Animals tend to use these e.g. to locate food sources or to find a suitable mate. In this study, the sex pheromone of the Indian meal moth, Plodia interpunctella, was analysed. Since this is an economically important species, it is mass-reared in labs and science centers worldwide for experimental purposes. A culture of these moths was brought into the lab at Lund University for studies and has after that served as a model species demonstrating up-wind pheromone-mediated male flight in different courses held by the university. As years went by, the culture got less successful in up-wind flights, most probably because of inbreeding and bottleneck effects, and therefore, a new culture was taken in. This study focuses on using various experiments to see if there was a behavioral and/or physiological difference between the two cultures. Results show a significant difference in behavioral traits (frequency of calling behavior in females and in male up-wind flights) but not in physiological traits (female pheromone production or male antennal response). This study discusses some effects of mass-reared lab cultures.

Abstract:

Control of the citrus pest, false codling moth (FCM), Thaumatotibia leucotreta Meyrick (Lepidoptera: Tortricidae) is crucial for the South African citrus industry. The economic losses and phytosanitary status of this pest, coupled with increased consumer awareness and demands, has created a need for effective, IPM-compatible control measures for use against the soil-dwelling life stages of FCM. Promising developments in the field of microbial control through the use of entomopathogenic fungi (EPF) and entomopathogenic nematodes (EPNs) have highlighted the need for research regarding pupation biology, behaviour and survival of FCM, as a good understanding of biology of the target organism is an important component of any biological control programme. The aim of this study was to improve the current understanding of FCM pupation habits through the manipulation of soil texture class, ground cover, shading, soil compaction, air temperature, and soil moisture in the laboratory. These findings would then be used to aid the biological control programmes using EPF and EPNs against FCM in the soil. Three soil texture classes (sandy loam, silt loam and silty clay loam) were obtained from orchards for use in the study. FCM larvae were allowed to drop into the soil of their own accord and the pupation behaviour that followed was then captured on film with pupae formed in the soil being kept in order to measure adult eclosion. In general, very few abiotic factors had a clear influence on FCM pupation. Larval wandering time and distance was short, but also variable between individuals. Distance did increase when soils were moist. Pupation depth was shallow, with pupal cocoons generally being formed on the soil surface. Depth of pupation was less than one centimetre for all abiotic conditions, with little burrowing into soil. Eclosion success was higher for sandier soils when these were dry and uncompacted, but the addition of both moisture and soil compaction increased FCM eclosion success. FCM was sensitive to desiccation when the soils were dry and temperature limits of 15 °C and 32 °C had a strongly negative impact on eclosion success. Preferences for particular abiotic conditions were limited to only certain moisture conditions when interacting with soil texture class and a preference for pupating in soil when it is available. Limited preference was found for particular soil textures despite this having a strong influence on eclosion success, but individuals did appear to pupate in close proximity to one another. Viable direct habitat manipulation for FCM control could not be identified. These results and all of the abiotic variables measured have important implications for EPF and EPN application, survival and persistence in the soil in order to improve the ability of these biological control agents to control FCM. These are discussed in each chapter.

Abstract:

Purpose: The objective was to study how sedentary behaviour (SB) and physical activity (PA)change during a 6-months multimodal lifestyle intervention including a Multimodal Lifestyle Intervention, a Multimodal Lifestyle and Medical food intervention and a control subgroup, for people with prodromal Alzheimer's disease (AD). Further, the aim was to explore the predictive value of outcome expectancies and self-efficacy beliefs on level of PA in the two intervention subgroups. Methods: A secondary analysis of existing data (n=66) from MIND-AD trial with a descriptive evaluation design was conducted. Descriptive and non-parametric statistical analysis were used for between- and within groups analysis. To explore the predictive value of a model with self-efficacy and outcome expectancies at baseline on PA at 6 months, regression analysis was conducted. Effect size was calculated for between-group and withingroup differences. Results: Objectively measured PA increased in the Multimodal Intervention subgroup. SB did not change during the intervention. Outcome expectancies for that impact of exercise is beneficial for health in the long run increased during the intervention. Participants higherinitial outcome expectancies for the impact of exercise would lead to less AD-related difficulties predicted higher PA level at 6 months. Self-efficacy for exercise or outcome expectancies for the impact of exercise on AD-related difficulties did not change during the intervention. Conclusions: PA increased in the Multimodal Intervention subgroup. This difference could not be shown with PA measured by questionnaire which indicates that objective measurements are better suited to measuring PA in people with prodromal AD than subjective measurements. Increased outcome expectancies for that impact of exercise arebeneficial for health in the long run demonstrate the participants strengthened intentions to improve their long-term health. Increasing outcome expectancies to manage AD-related difficulties can be an important part of interventions targeting PA in people with prodromal AD.

Abstract:

Breast cancer is a devastating disease that affects thousands of women every year influencing their psychological and physical well-being for many years after being diagnosed. The goal of the current study was to determine if there are distinct trajectories of functioning among breast cancer patients in the domains of negative psychological adjustment, positive psychological adjustment, and physical adjustment. This was accomplished using growth mixture modeling. Another goal of this study was to determine whether demographic, medical, and psychosocial variables were able to distinguish among the trajectories. The study combined women from two samples spanning 10 years providing a sample size of 376 women diagnosed and treated for breast cancer. These women were recruited to participate in a 10-week cognitive behavioral stress management intervention and were either randomized to the 10-week experimental condition or a one-day control group. It was hypothesized that distinct trajectories would emerge for each of the domains and that psychosocial variables (i.e., social support, benefit finding, and emotional approach coping) would distinguish among the trajectories. This study was able to statistically identify multiple classes or trajectories of adjustment, consistent with findings reported by Helgeson and colleagues (2004) and Donovan and colleagues (2007). It is difficult to say, however, whether these classes differ in clinically significant ways. The present study also provides a cautionary note to researchers who intend to use growth mixture modeling to identify different trajectories of functioning and the limitations associated with this statistical technique. First, it is important to start this process with strong empirical or theoretical support for the possibility of different classes or trajectories. Without this foundation it becomes difficult to justify why a certain number of classes were chosen. Another limitation of this statistical approach is that there is not a standard method for determining the best number of classes. There are conflicting opinions among researchers in the field about the best fit index to use when the multiple fit indices do not converge. A serious issue related to this is the fact that classes are used for interpreting results and drawing conclusions and inferences. Therefore, clinicians using GMM must be careful when deciding on the number of classes and the clinical inferences drawn from these analyses. Further research needs to be conducted validating these statistical techniques.

Abstract:

A traça das crucíferas, Plutella xylostella (L.) (Lepidoptera: Plutellidae), é uma das pragas mais importantes de Brassicaceae no Brasil e no mundo, causando sérios danos em repolho, couve-flor e couve comum, entre outras. O objetivo desta pesquisa foi estudar os parâmetros populacionais e a resposta comportamental de P. xylostella criada por dezoito gerações, utilizando três variedades: Brassica oleracea var. acephala couve manteiga hibrida HS-20, B. oleracea var. italica couve brócolis Piracicaba e B. oleracea var. capitata repolho Bob Cat. Para condução dos experimentos foram separados três lotes de pupas de P. xylostella da criação mantida no laboratório, no qual foram utilizadas apenas folhas de couve para sua manutenção. Cada lote foi mantido em substrato diferente, ou seja, a criação inicial foi dividia em três populações tendo como variável o substrato alimentar e de oviposição utilizado na criação (couve, brócolis ou repolho). Com os dados biológicos de P. xylostella foram estimados os parâmetros populacionais de tabela de vida de fertilidade a cada três gerações, comparando-se as cultivares testadas em relação ao desenvolvimento, sobrevivência e reprodução da praga. Além disso, lotes de insetos oriundos de cada substrato de criação foram separados a cada três gerações para realização de testes de dupla e múltipla chance de escolha (preferência para alimentação e oviposição). Os parâmetros populacionais de P. xylostella indicam que as brassicáceas testadas permitem o crescimento populacional do inseto nos respectivos hospedeiros. O comportamento de seleção hospedeira na fase pré-imaginal e imaginal de P. xylostella não é afetado pela experiência alimentar e de oviposição nos substratos testados até a geração F18.
The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the most important pests of Brassicaceae in Brazil and worldwide, causing serious damage to cabbage, cauliflower and kale common, among others. The aim of this research was to study the population parameters and the behavioral response of P. xylostella reared for eighteen generations, using three varieties: Brassica oleracea var. acephala - cabbage hybridizes HS-20, B. oleracea var. italica - Piracicaba broccoli and B. oleracea var. capitata - cabbage Bob Cat. To conduct the experiments were separate three batches of DBM from pupae held in the laboratory setting, in which only kale leaves were used for maintenance. Each batch was kept at different substrate, namely the initial rearing was divided into three populations having as variable the feeding and oviposition substrate used in rearing (kale, broccoli, and cabbage). With biological data of P. xylostella were estimated the population parameters of fertility life table every three generations, comparing the tested cultivars in relation to the development, survival and reproduction of the pest. Moreover, lots of insects derived from each rearing substrate were separated every three generations for performing dual choice and multiple-choice tests (preference for feeding and oviposition). The population parameters of P. xylostella indicate that brassicas tested allow the insect population growth in their hosts. The host selection behavior in pre-imaginal and imaginal stage of P. xylostella is not affected by food and oviposition experience on substrates up to F18 generation.

Abstract:

Cette thèse considère l'apprentissage de motifs récurrents dans la perception multimodale. Elle s'attache à développer des modèles robotiques de ces facultés telles qu'observées chez l'enfant, et elle s'inscrit en cela dans le domaine de la robotique développementale.Elle s'articule plus précisément autour de deux thèmes principaux qui sont d'une part la capacité d'enfants ou de robots à imiter et à comprendre le comportement d'humains, et d'autre part l'acquisition du langage. A leur intersection, nous examinons la question de la découverte par un agent en développement d'un répertoire de motifs primitifs dans son flux perceptuel. Nous spécifions ce problème et établissons son lien avec ceux de l'indétermination de la traduction décrit par Quine et de la séparation aveugle de source tels qu'étudiés en acoustique.Nous en étudions successivement quatre sous-problèmes et formulons une définition expérimentale de chacun. Des modèles d'agents résolvant ces problèmes sont également décrits et testés. Ils s'appuient particulièrement sur des techniques dites de sacs de mots, de factorisation de matrices et d'apprentissage par renforcement inverse. Nous approfondissons séparément les trois problèmes de l'apprentissage de sons élémentaires tels les phonèmes ou les mots, de mouvements basiques de danse et d'objectifs primaires composant des tâches motrices complexes. Pour finir nous étudions le problème de l'apprentissage d'éléments primitifs multimodaux, ce qui revient à résoudre simultanément plusieurs des problèmes précédents. Nous expliquons notamment en quoi cela fournit un modèle de l'ancrage de mots acoustiques
This thesis focuses on learning recurring patterns in multimodal perception. For that purpose it develops cognitive systems that model the mechanisms providing such capabilities to infants; a methodology that fits into thefield of developmental robotics.More precisely, this thesis revolves around two main topics that are, on the one hand the ability of infants or robots to imitate and understand human behaviors, and on the other the acquisition of language. At the crossing of these topics, we study the question of the how a developmental cognitive agent can discover a dictionary of primitive patterns from its multimodal perceptual flow. We specify this problem and formulate its links with Quine's indetermination of translation and blind source separation, as studied in acoustics.We sequentially study four sub-problems and provide an experimental formulation of each of them. We then describe and test computational models of agents solving these problems. They are particularly based on bag-of-words techniques, matrix factorization algorithms, and inverse reinforcement learning approaches. We first go in depth into the three separate problems of learning primitive sounds, such as phonemes or words, learning primitive dance motions, and learning primitive objective that compose complex tasks. Finally we study the problem of learning multimodal primitive patterns, which corresponds to solve simultaneously several of the aforementioned problems. We also details how the last problems models acoustic words grounding

Abstract:

Children with Autism Spectrum Disorder (ASD) have difficulties with social interaction that affect their early learning through play. Systematic reviews were conducted on the effectiveness of Social Stories™ (SS™), Self Video Modelling (SVM) and Peer Video Modelling (PVM) to teach social behaviour to such children. Study 1 compared their effectiveness for teaching three core play skills to 18 young children with ASD: initiating play, turn taking and finishing play; using a counterbalancing design across skills and play materials so that each participant received each intervention. At intake, participants’ ages, Vineland Adaptive Behavior Scale and PLS-3 scores were assessed. The three core skills were observed with good interobserver (97.3%) and procedural (100%) reliability and quantified using a specifically designed scale. The social validity of target skills and interventions was assessed using a Likert scale. All interventions showed evidence of significant improvement. Non-parametric repeated measures ANOVA and post-hoc Wilcoxon tests showed that SVM was superior to SS™ and PVM. Such superiority was evident for initiating play and turn taking but not for finishing play. There was no significant association between the intake variables and either the degree of change between baseline and post-intervention or the post-intervention scores themselves for SS™. Change following SVM was positively related to the Vineland composite score and its motor skills domain score. Post-intervention scores for SVM were positively related to the Vineland composite scores and its communication, daily living and motor skills domain scores as well as all three PLS-3 scores. Change following PVM was related to the Vineland maladaptive score. The target skills and interventions had high social validity. Study 2 showed that more sustained intervention over time resulted in improvement for those who did less well initially. Overall, the research provides encouraging evidence that these interventions are effective in teaching play behaviours to young children with ASD.

Abstract:

Bumblebees have undergone dramatic declines both in Britain and further afield during the last century. Bumblebees provide a crucial pollination service to both crops and wild flowers. For these reasons, they have received a great deal of research attention over the years. However, the ecology of wild bumblebee nests and the interactions between nests and other species, particularly vertebrates has been somewhat understudied. This is largely due to the difficulty in finding sufficient nests for well replicated study and a lack of appropriate methods of observation. Here, methods for locating bumblebee nests were trialled. It was found that a specially trained bumblebee nest detection dog did not discover nests any faster than people who had received minimal instruction. Numbers of nest site searching queens provide a reliable indication of suitable nesting habitat (i.e. places where nests are more likely to be found). In order to investigate aspects of bumblebee nesting ecology wild nests were observed by filming or regular observations by either researchers or members of the public. Some buff-tailed bumblebee (Bombus terrestris) nests were collected and all the bumblebees were genotyped to identify any foreign individuals. A review of British mammalian dietary literature was conducted to identify those that predate bumblebees. Great tits (Parus major) were filmed predating bumblebees at nests and it was clear from the literature and observations that badger (Meles meles), pine martens (Martes martes) and hedgehogs (Erinaceus europaeus) predate bumblebee nests, as well as the wax moth (Aphomia sociella). No evidence for predation by any other vertebrate species was found. Behaviours recorded included parasitism by Psithyrus, apparent nectar theft and possible usurpation by true bumblebees, egg-dumping by foreign queens and drifting and drifter reproduction by foreign workers. These events may cause harm to colonies (for example, through horizontal transmission of pathogens, or exploitation of the host nest’s resources). Alternatively where for example, usurpation by true bumblebees, egg-dumping or drifting is successful, these alternative reproductive strategies may increase the effective population size by enabling a single nest to produce reproductives of more than one breeding female. These data found that wild buff-tailed bumblebees (B. terrestris) nests with a greater proportion of workers infected with Crithidia bombi were less likely to produce gynes than those with fewer infected workers. Gyne production also varied dramatically between years. There is a growing body of evidence that a class of frequently used insecticides called neonicotinoids are negatively impacting bumblebees. An experiment was conducted using commercial colonies of buff-tailed bumblebees (B. terrestris) which were fed pollen and nectar which had been treated with the neonicotinoid imidacloprid at field realistic, sub-lethal levels. Treated colonies, produced 85-90% fewer gynes than control colonies. If this trend is representative of natural nests feeding on treated crops, for example, oilseed rape and field beans or garden flowers, then this would be expected to cause dramatic population declines. In this thesis methods for locating bumblebee nests have been tested, new behaviours have been identified (for example, egg-dumping by queens and predation by great tits) and estimations for rates of fecundity and destruction by various factors have been provided. Doubt has been cast over the status of some mammals as predators of bumblebee nests and estimates for gyne production, nest longevity, etc, have been given. More work is needed, especially observations of incipient nests as this is when the greatest losses are thought to occur.

Abstract:

Chez les insectes où les males chantent en chorus, l’interférence locale de signaux impose des contraintes majeures à des femelles qui doivent évaluer les mâles individuellement. Les mâles subis des difficultés pour évaluer la compétitivité de leurs voisins et pour montrer clairement aux femelles les caractéristiques de leurs propres chants. J’ai analysé différents aspects de cette problématique chez deux espèces acoustiques : chez la sauterelle ephippiger et une pyrale nocturne qui émettent leurs signaux au sein de regroupements. Nos expériences ont mis en évidence certains mécanismes comportementaux permettant aux femelles de localiser les meuliers males et d’autres permettant aux mâles de se communiquer efficacement et percevoir leur environnement acoustique
In acoustic insects where males sing in choruses, local signal interference may present major difficulties for females evaluating and individual males. Males too may be prevented from assessing the competitivity of their neighbors as well as from advertising the characteristics of their own signals to females in a clear manner. Moreover, the background noise from local signals may prevent both sexes from perceiving other sounds in the environment, e.g. predator cues. I studied these problems at several levels in two acoustic insect species: in which males broadcast their advertisement songs while remaining in dense clusters. The experiments revealed behavioral mechanisms with which females can identify favored males and others with which males can communicate effectively

Abstract:

Les lesions cerebrals per traumatismes craniencefàlics són la causa més freqüent de defunció en els accidents de trànsit en els que estan implicats vehicles de dues rodes. Malgrat la provada eficàcia de l'ús del casc per amortir les lesions en cas d'accidents, molts adolescents i joves no el fan servir o fan un ús incorrecte.
El principal objectiu d'aquesta investigació és identificar les variables que millor prediuen l'ús del casc entre els adolescents. En la recerca es combinen la metodologia quantitativa i qualitativa i consta de dues fases. A la primera fase participen 876 estudiants de secundària (46,8% nois) amb edats compreses entre 14 i 18 anys. A la segona fase, s'estudien quatre casos d'adolescents que han patit un accident greu circulant amb ciclomotor i que no portaven el casc o feien un ús incorrecte. Els resultats suggereixen que l'edat i la influència social són les variables més rellevants per predir l'ús continuat del casc entre els adolescents. De l'estudi se'n deriven estratègies d'intervenció per incrementar l'ús del casc entre els dolescents.
The cerebral injuries as a result of cranio-encephalic traumatism are the most frequent cause of death in two-wheel vehicle accidents. In spite of the proven effectiveness of the use of the helmet to deaden injuries in the event of accidents, many teenagers and youngsters do not use it or use it incorrectly. The main goal of this research is to identify the variables that best predict the use of the helmet among adolescents. The research combines the use of quantitative and qualitative methodology and consists of two phases. 876 secondary students (46,8% boys) between 14 and 18 took part in the 1st phase. The 2nd phase consists in the study of 4 cases of teenagers who have suffered severe moped accidents while driving without helmet or using it incorrectly. The results suggest that the age and the social influence are the most relevant variables to predict the regular use of the helmet among the teenagers. The study results in intervention strategies to increase the use of the helmet among adolescents.
