description: Abstract Background Measures to assess neighborhood environments are needed to better understand the salient features that may enhance outdoor physical activities, such as walking and bicycling for transport or leisure. The purpose of this study was to derive constructs to describe neighborhoods using both primary (neighborhood audit) and secondary (geographic information systems) data. Methods We collected detailed information on 10,770 road segments using an audit and secondary data. The road segment sample was randomly split into an exploratory (60%) and validation sample (40%) for cross-validation. Using the exploratory sample (n = 6,388), seven a priori constructs were assessed separately (functionality, safety, aesthetics, destinations, incivilities, territorality, social spaces) by urbanicity using multi-group confirmatory factor analysis (CFA). Additionally, new a posteriori constructs were derived using exploratory factor analysis (EFA). For cross-validation (n = 4,382), we tested factor loadings, thresholds, correlated errors, and correlations among a posteriori constructs between the two subsamples. Two-week test-retest reliability of the final constructs using a subsample of road segments (n = 464) was examined using Spearman correlation coefficients. Results CFA indicated the a priori constructs did not hold in this geographic area, with the exception of physical incivilities. Therefore, we used EFA to derive a four-factor solution on the exploratory sample: arterial or thoroughfare, walkable neighborhood, physical incivilities, and decoration. Using CFA on the validation sample, the internal validity for these a posteriori constructs was high (range 0.43 to 0.73) and the fit was acceptable. Spearman correlations indicated the arterial or thoroughfare factor displayed near perfect reliability in both urban and rural segments (r = 0.96). Both the physical incivilities factor and the walkable neighborhood factor had substantial to near perfect reliability in both urban and rural segments (r = 0.77 to 0.78 and r = 0.79 to 0.82, respectively). The decoration factor displayed moderate reliability in urban segments (r = 0.50; 95% CI: 0.38–0.60) and lower reliability in rural segments (r = 0.39; 95% CI: 0.25–0.52). Conclusion The results of our analyses yielded four reliably and objectively measured constructs that will be used to explore associations with physical activity in urban and rural North Carolina. These constructs should be explored in other geographic areas to confirm their usefulness elsewhere.

description: This paper explores the relationship between the inner economical structure of communities and their population distribution through a rank-rank analysis of official data, along statistical physics ideas within two techniques. The data is taken on Italian cities. The analysis is performed both at a global (national) and at a more local (regional) level in order to distinguish "macro" and "micro" aspects. First, the rank-size rule is found not to be a standard power law, as in many other studies, but a doubly decreasing power law. Next, the Kendall and the Spearman rank correlation coefficients which measure pair concordance and the correlation between fluctuations in two rankings, respectively, - as a correlation function does in thermodynamics, are calculated for finding rank correlation (if any) between demography and wealth. Results show non only global disparities for the whole (country) set, but also (regional) disparities, when comparing the number of cities in regions, the number of inhabitants in cities and that in regions, as well as when comparing the aggregated tax income of the cities and that of regions. Different outliers are pointed out and justified. Interestingly, two classes of cities in the country and two classes of regions in the country are found. "Common sense" social, political, and economic considerations sustain the findings. More importantly, the methods show that they allow to distinguish communities, very clearly, when specific criteria are numerically sound. A specific modeling for the findings is presented, i.e. for the doubly decreasing power law and the two phase system, based on statistics theory, e.g., urn filling. The model ideas can be expected to hold when similar rank relationship features are observed in fields. It is emphasized that the analysis makes more sense than one through a Pearson value-value correlation analysis.

description: Hong-Ou-Mandel (HOM) interference between independent photon sources (HOMI-IPS) is the fundamental block for quantum information processing, such as quantum gate, Shor's algorithm, Boson sampling, etc. All the previous HOMI-IPS experiments were carried out in time-domain, however, the spectral information during the interference was lost, due to technical difficulties. Here, we investigate the HOMI-IPS in spectral domain using the recently developed fast fiber spectrometer, and demonstrate the spectral distribution during the HOM interference between two heralded single-photon sources, and two thermal sources. This experiment can not only deepen our understanding of HOMI-IPS in the spectral domain, but also be utilized to improve the visibility by post-processing spectral filtering.

description: Abstract
                Background
                A model for statewide dissemination of evidence-based treatment (EBT) for traumatized youth was piloted and taken to scale across North Carolina (NC). This article describes the implementation platform developed, piloted, and evaluated by the NC Child Treatment Program to train agency providers in Trauma-Focused Cognitive Behavioral Therapy using the National Center for Child Traumatic Stress Learning Collaborative (LC) Model on Adoption & Implementation of EBTs. This type of LC incorporates adult learning principles to enhance clinical skills development as part of training and many key implementation science strategies while working with agencies and clinicians to implement and sustain the new practice.
                Methods
                Clinicians (n = 124) from northeastern NC were enrolled in one of two TF-CBT LCs that lasted 12 months each. During the LC clinicians were expected to take at least two clients through TF-CBT treatment with fidelity and outcomes monitoring by trainers who offered consultation by phone and during trainings. Participating clinicians initiated treatment with 281 clients. The relationship of clinician and client characteristics to treatment fidelity and outcomes was examined using hierarchical linear regression.
                Results
                One hundred eleven clinicians completed general training on trauma assessment batteries and TF-CBT. Sixty-five clinicians met all mastery and fidelity requirements to meet roster criteria. One hundred fifty-six (55%) clients had fidelity-monitored assessment and TF-CBT. Child externalizing, internalizing, and post-traumatic stress symptoms, as well as parent distress levels, decreased significantly with treatment fidelity moderating child PTSD outcomes. Since this pilot, 11 additional cohorts of TF-CBT providers have been trained to these roster criteria.
                Conclusion
                Scaling up or outcomes-oriented implementation appears best accomplished when training incorporates: 1) practice-based learning, 2) fidelity coaching, 3) clinical assessment and outcomes-oriented treatment, 4) organizational skill-building to address barriers for agencies, and 5) linking clients to trained clinicians via an online provider roster. Demonstrating clinician performance and client outcomes in this pilot and subsequent cohorts led to legislative support for dissemination of a service array of EBTs by the NC Child Treatment Program.

description: Kuranishi structures were introduced in the 1990s by Fukaya and Ono for the purpose of assigning a virtual cycle to moduli spaces of pseudoholomorphic curves that cannot be regularized by geometric methods. Starting from the same core idea (patching local finite dimensional reductions) we develop a theory of topological Kuranishi atlases and cobordisms that transparently resolves algebraic and topological challenges in this virtual regularization approach. It applies to any Kuranishi-type setting, e.g. atlases with isotropy, boundary and corners, or lack of differentiable structure.

Confidence regions for repeated measures ANOVA power curves based on estimated covariance
Creators: name: Stewart, Paul
Publisher: name: BioMed Central Ltd
Year: 2013

description: Abstract Background Using covariance or mean estimates from previous data introduces randomness into each power value in a power curve. Creating confidence intervals about the power estimates improves study planning by allowing scientists to account for the uncertainty in the power estimates. Driving examples arise in many imaging applications. Methods We use both analytical and Monte Carlo simulation methods. Our analytical derivations apply to power for tests with the univariate approach to repeated measures (UNIREP). Approximate confidence intervals and regions for power based on an estimated covariance matrix and fixed means are described. Extensive simulations are used to examine the properties of the approximations. Results Closed-form expressions are given for approximate power and confidence intervals and regions. Monte Carlo simulations support the accuracy of the approximations for practical ranges of sample size, rank of the design matrix, error degrees of freedom, and the amount of deviation from sphericity. The new methods provide accurate coverage probabilities for all four UNIREP tests, even for small sample sizes. Accuracy is higher for higher power values than for lower power values, making the methods especially useful in practical research conditions. The new techniques allow the plotting of power confidence regions around an estimated power curve, an approach that has been well received by researchers. Free software makes the new methods readily available. Conclusions The new techniques allow a convenient way to account for the uncertainty of using an estimated covariance matrix in choosing a sample size for a repeated measures ANOVA design. Medical imaging and many other types of healthcare research often use repeated measures ANOVA.

description: Background: Throughout history touch has played a central role in medicine1. Clinical technology, AI systems and virtual consultations introduced during the pandemic have reduced opportunities for students to learn the value of touch 2.
 In response, Imperial College School of Medicine (ICSM) designed a novel, interdisciplinary session as part of the MBBS curriculum. This presentation highlights how the session improved student confidence during clinical examinations and showcases why teaching early years students the importance of therapeutic touch is beneficial 3.

 Summary of Work: ICSM Phase 1a (Year 1) students within their first month of the MBBS course attended a blended 4-part series ‘Autonomy and Touch’, which included;
 Ethical principles of touch and consent, Historical perspectives, Therapeutic touch in clinical practice, The use of touch in allied health professional roles , Student peer-peer examination

 Students were asked to complete a pre and post course confidence survey on the following themes: gaining consent, examining someone unknown, how a person feels when they are examined, respect for patient diversity and recognition of how examination techniques differ between healthcare professions.

 Summary of Results: 203 students took part in the post-session questionnaire.
 All 5 questions showed an improvement in confidence rating, with the highest improvements seen in how a person feels (when being examined) and respect for patient diversity. There was an improvement of 20.33% and 15.41% respectively of students choosing the highest confidence rating for these questions.

 Discussion and Conclusion: Imperial College School of Medicine recognise that the ‘Autonomy and Touch’ session benefits students in the early stages of the MBBS programme, preparing them for a career in clinical practice and improving their relationships with patients and peers. Incorporating this peer-based learning session into the curriculum has improved student confidence in examination technique and allows students to empathise from a patients’ perspective.

Real estate surfaces appraisal

description: In the appraisal of the market value of the properties are applied two important surface indexes: the market surface ratio of the secondary surfaces and the ratio of the site value to total value (allocation method). The measure of both these indexes can be revealed difficult: the data collection of the surface trade ratio in the market can get different results and in practice often the valuer refolds on the fixed coefficients brought in the handbooks and in the circulars of the public administration; the appraisal of the ratio of the site, especially in the central zones and for ancient buildings, where besides the incidence is higher, is developed extrapolating the ratios from the peripheral zones for new building or falling back on the publications of real estate sector. For the market comparison methods are proposed a series of test of surface trade ratio and land value ratio to foresee the effect on the appraisal result.

Cost-effectiveness of using the Cervex-Brush (broom) compared to the elongated spatula for collection of conventional cervical cytology samples within a high-burden HIV setting: a model-based analysis
Creators: name: Chibwesha, Carla J
Publisher: name: BioMed Central
Year: 2015

description: Abstract Background From 2010 to 2014, approximately 2 million Pap smears from HIV-infected women were submitted to the South African National Health Laboratory Services (NHLS) through the national cervical cancer screening programme. The objective of this analysis was to determine whether using the plastic Cervex brush (“broom”) would be a cost-effective approach to improve cytology specimen quality as compared to the wooden spatula used currently. Methods A decision analysis model was built using the expected adequacy rates for samples collected with the spatula (<$0.02) and broom ($0.23) and the probability of detecting cervical dysplasia. NHLS data was used for testing volumes and rates of HIV-positivity, suitability of specimens, and presence of endocervical cells. Expected positivity of Pap smears in HIV-infected women (73 %), odds ratios of the effectiveness of the broom (OR: 1.57), and improved sensitivity when endocervical cells present (OR: 1.89) are from literature. NHLS costs were used for the collection devices and conventional cytology ($4.89). Cost of clinic visit is from WHO CHOICE ($8.36). Results In 2010, 80 % of specimens submitted to NHLS were adequate for evaluation; in 2014, only 54 % met the same criteria. For HIV-infected women, according to the guidelines model, using the wooden spatula costs $6.25 million per year, $16.79 per woman tested. Under intended practice, for each additional HSIL case detected among HIV-infected women, the South African cervical cancer screening programme could save $13.64 (95 % CI: $13.52 to $13.76) by using the broom as its standard of care collection device through increased collection of endocervical cells and consequent reduction in repeat Pap smears. Conclusion Under a wide range of parameters tested using a simulation model, the more expensive plastic broom could save the South African cervical cancer screening programme money and increase detection of high-grade cervical dysplasia in HIV-infected women compared to the current wooden spatula.

description: Nanodot deposition on a side surface of a rectangular sample and digital image correlation are used to quantify the in-plane strain fields associated with the propagation of a shear band in a PdNiP bulk metallic glass,induced by rolling. Within the resolution of the method related to an average inter-dot distance of 100 nm, deformation is found to be highly localized at the shear bands, while alternating areas with a size of 100 - 400 nm with opposite local shear strains are found. This phenomenon substantiates a local stick-slip nature of shear band propagation during the metallic glass deformation, even during rolling.

How do you like wind farms? Understanding people’s preferences about new energy landscapes with choice experiments
Creators: name: Vecchiato, Daniel
Publisher: name: Aestimum
Year: 2014

description: This study aims at understanding people’s preferences about wind energy in order to foster the installation of new power plants in Italy. The application of a choice experiment allowed the willingness to pay to be estimated for the following attributes: wind turbines position, turbine height, number of turbines per wind farm and minimum distance of the farm from houses/coast. According to our results the majority of people perceive wind energy positively and prefer offshore wind farms. People recognise the importance of preserving landscape and think that wind turbines do not improve its beauty. In this respect the installation of new wind farms can be considered a second-best solution in terms of landscape preservation, but a ﬁrst-best solution if other aspects are taken into account.

description: We show that initially localized and uncorrelated two-particles quantum wavepackets evolving in a one-dimensional discrete lattice become strongly entangled while drifting under the action of an harmonic AC field resonant with doubled Bloch oscillations promoted by a static DC field. Although partial entanglement is achieved when the AC field is resonant with the single-particle Bloch oscillations, it is strongly limited by the survival of anti-correlated unbounded states. We further show that the phase dependence of the wavepacket centroid velocity is similar to the semiclassical behavior depicted by a single-particle. However, the drift velocity exhibits a non-trivial non-monotonic dependence on the interaction strength, vanishing in the limit of uncorrelated particles, that unveils its competing influence on unbounded and bounded states.

description: We provide a systematic way of dimensional reduction for $(4+2n)$-dimensional $U(N)$ supersymmetric Yang-Mills (SYM) theories ($n=0,1,2,3$) and their mixtures compactified on two-dimensional tori with background magnetic fluxes, which preserve a partial ${\mathcal N}=1$ supersymmetry out of full ${\mathcal N}=2,3$ or $4$ in the original SYM theories. It is formulated in an $\mathcal N=1$ superspace respecting the unbroken supersymmetry, and the four-dimensional effective action is written in terms of superfields representing $\mathcal N=1$ vector and chiral multiplets, those arise from the higher-dimensional SYM theories. We also identify the dilaton and geometric moduli dependence of matter Kähler metrics and superpotential couplings as well as of gauge kinetic functions in the effective action. The results would be useful for various phenomenological/cosmological model buildings with SYM theories or D-branes wrapping magnetized tori, especially, with mixture configurations of them with different dimensionalities from each other.

description: In recent years, the media impact of the damage from electromagnetic fields generated by high voltage power lines on human health has grown considerably. Hence, judges increasingly require the assessment of the compensation concerning the land depreciation for the “perception” of the health risk from land market operators, regardless of the land use and the ascertainment of the health damage. The aim of this paper is the assessment of the “perceptive” devaluation of the Apulia agricultural lands in the presence of high voltage power lines and for different crop systems, in order to present a methodological approach that could support the experts appointed by judges. The analysis clearly shows that the perception of the risk of damage to human health is strongly felt by land market operators, causing an average devaluation of 33% and even up to 50% for greenhouses and farm buildings.

description: Most modern astrophysical datasets are multi-dimensional; a characteristic that can nowadays generally be conserved and exploited scientifically during the data reduction/simulation and analysis cascades. Yet, the same multi-dimensional datasets are systematically cropped, sliced and/or projected to printable two-dimensional (2-D) diagrams at the publication stage. In this article, we introduce the concept of the "X3D pathway" as a mean of simplifying and easing the access to data visualization and publication via three-dimensional (3-D) diagrams. The X3D pathway exploits the facts that 1) the X3D 3-D file format lies at the center of a product tree that includes interactive HTML documents, 3-D printing, and high-end animations, and 2) all high-impact-factor & peer-reviewed journals in Astrophysics are now published (some exclusively) online. We argue that the X3D standard is an ideal vector for sharing multi-dimensional datasets, as it provides direct access to a range of different data visualization techniques, is fully-open source, and is a well defined ISO standard. Unlike other earlier propositions to publish multi-dimensional datasets via 3-D diagrams, the X3D pathway is not tied to specific software (prone to rapid and unexpected evolution), but instead compatible with a range of open-source software already in use by our community. The interactive HTML branch of the X3D pathway is also actively supported by leading peer-reviewed journals in the field of Astrophysics. Finally, this article provides interested readers with a detailed set of practical astrophysical examples designed to act as a stepping stone towards the implementation of the X3D pathway for any other dataset.

description: We consider the problem of counting the set of $\mathscr{D}_{a,b}$ of Dyck paths inscribed in a rectangle of size $a\times b$. They are a natural generalization of the classical Dyck words enumerated by the Catalan numbers. By using Ferrers diagrams associated to Dyck paths, we derive formulas for the enumeration of $\mathscr{D}_{a,b}$ with $a$ and $b$ non relatively prime, in terms of Catalan numbers.

description: Protected area management is hindered by the different perspective that institutional stakeholders have on the main, in some cases, contrasting objectives to be reached. In order to get satisfying solutions, it is needed that the structure of the preferences among stakeholders be sufficiently known and defined. In this paper, the choice modelling approach is used to assess the importance of conflicting rival objectives, referring as a case study to the coastal protected area along the Tyrrhenian coast of Italy named “Salina di Tarquinia”. Results show that stakeholders prefer a centralized regime of management, probably to overcome all contrasts that numerous authorities having a right on this area usually exercised in the recent past.

description: Abstract Background Several studies have demonstrated a link between young people’s sexual behavior and levels of parental monitoring, parent-child communication, and parental discipline in Western countries. However, little is known about this association in African settings, especially among young people living in high poverty settings such as urban slums. The objective of the study was to assess the influence of parental factors (monitoring, communication, and discipline) on the transition to first sexual intercourse among unmarried adolescents living in urban slums in Kenya. Methods Longitudinal data collected from young people living in two slums in Nairobi, Kenya were used. The sample was restricted to unmarried adolescents aged 12–19 years at Wave 1 (weighted n = 1927). Parental factors at Wave 1 were used to predict adolescents’ transition to first sexual intercourse by Wave 2. Relevant covariates including the adolescents’ age, sex, residence, school enrollment, religiosity, delinquency, and peer models for risk behavior were controlled for. Multivariate logistic regression models were used to assess the associations of interest. All analyses were conducted using Stata version 13. Results Approximately 6 % of our sample transitioned to first sexual intercourse within the one-year study period; there was no sex difference in the transition rate. In the multivariate analyses, male adolescents who reported communication with their mothers were less likely to transition to first sexual intercourse compared to those who did not (p < 0.05). This association persisted even after controlling for relevant covariates (OR: ≤0.33; p < 0.05). However, parental monitoring, discipline, and communication with their fathers did not predict transition to first sexual intercourse for male adolescents. For female adolescents, parental monitoring, discipline, and communication with fathers predicted transition to first sexual intercourse; however, only communication with fathers remained statistically significant after controlling for relevant covariates (OR: 0.30; 95 % C.I.: 0.13–0.68). Conclusion This study provides evidence that cross-gender communication with parents is associated with a delay in the onset of sexual intercourse among slum-dwelling adolescents. Targeted adolescent sexual and reproductive health programmatic interventions that include parents may have significant impacts on delaying sexual debut, and possibly reducing sexual risk behaviors, among young people in high-risk settings such as slums.
Does Exclusion of Extreme Reporters of Energy Intake Reliably Make Results Less Biased in Nutrition Studies?

description: The study of energy intake (EI) is of vital interest in nutrition/obesity research. Methods to measure EI are roughly divided into several types: (respiratory) indirect calorimetry, doubly-labeled water (DLW), direct observation and self-reporting. Self-reported energy intake is convenient method, however, it is well known to be error-prone. To address the issue of rEI, several methods have been invented. Among them Goldberg cutoff is broadly used to exclude implausible reporters of EI. However, whether or not the use of this procedure actually reduces bias has not been evaluated in empirical studies and no formal theoretical foundation (i.e., mathematical proof) for claiming that it does so has been shown. In this study, we demonstrate whether applying Goldberg cutoff to a dataset reliably reduces bias in nutrition/obesity studies through the analysis of two independent data sources: Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy (CALERIE) Phase 2 and The Interactive Diet and Activity Tracking in American Association of Retired Persons (IDATA).

description: Today, the suburban is the predominant portion of each area. It combines the main features of urban and rural areas and it is therefore difficult to locate. Despite these difficulties, the policy makers should zone their territories and incorporate the results in the existing planning instruments. The distinction among territories is important to better orient local actions. This paper proposes aims to understand how some Italian regional legislators have defined the surrounding areas in their zoning laws and plans in force.

description: Massive black holes at galaxy center may tear apart a star when the star passes occasionally within the disruption radius, which is the so-called tidal disruption event(TDE). Most TDEs radiate with thermal emission resulted from the accretion disk, but three TDEs have been detected in bright non-thermal X-ray emission, which is interpreted as arising from the relativistic jets. Search for high-energy gamma-ray emission from one relativistic TDE (Swift J164449.3+573451) with the \textsl{Fermi} Large Area Telescope (LAT) has yielded non-detection. In this paper, we report the search for high energy emission from the other two relativistic TDEs (Swift J2058.4+0516 Swift J1112.2-8238) during the flare period. No significant GeV emission is found, with an upper limit fluence in LAT energy range being less than $1\%$ of that in X-rays. Compared with gamma-ray bursts (GRBs) and blazars, these TDEs have the lowest flux ratio between GeV emission and X-ray emission. The non-detection of high-energy emission from relativistic TDEs could be due to that the high-energy emission is absorbed by soft photons in the source. Based on this hypothesis, upper limits on the bulk Lorentz factors, $Γ\la 30$, are then obtained for the jets in these TDEs. We also search for high-energy gamma-ray emission from the nearest TDE discovered to date, ASASSN-14li. No significant GeV emission is found and an upper limit of $L(\rm 0.1-10 GeV)\le 4.4\times 10^{42}$ erg s$^{-1}$ (at $95\%$ confidence level) is obtained for the first $10^{7}$ s after the disruption.

description: Abstract Background The use of tocolytic hospitalization in antenatal care is controversial and worthy of more research. We investigated individual, institutional, and area factors that affect the use of tocolytic hospitalizations in Taiwan where fertility has rapidly declined. Methods Longitudinal data from the 1996 to 2004 National Health Insurance Research Database in Taiwan were used to identify tocolytic hospitalizations. The probit model was used to estimate factors associated with tocolytic hospitalizations. Results The decline in fertility was significantly associated with the probability of tocolytic hospitalizations. Several physician and institutional factors-including physician's age, hospital ownership, accreditation status, bed size, and teaching status-were also significantly correlated to the dependent variables. Conclusions The provision of inpatient tocolysis is influenced not only by clinical considerations but also by physician, institutional, and area factors unrelated to clinical need. Fertility declines in Taiwan may have led obstetricians/gynecologists to provide more tocolysis to make up for their lost income. If the explanation is further validated, reimbursement policies may need to be reviewed to correct for overuse of inpatient tocolysis. The correlation could also be explained by the increasing use of artificial reproductive technologies and higher social value of newborns. In addition, the physician and institutional variations observed in the study indicate potential misuse of inpatient tocolysis that warrant further investigation.

description: Since the 1970s, the cochlear implant (CI) is a widespread device to restore bad or missing hearing function. For this, electrodes which stimulate the auditory nerve fiber (ANF) are usually inserted in the scala tympani (ST). However, in case of an obstructed or ossified ST, electrode insertion becomes impeded or even impossible. Therefore, alternative locations for insertions are needed. The aim of this thesis is to compare the ANF excitation behavior between electrodes that are inserted in the scala vestibuli (SV), the other large cochlear duct, and ST-positioned electrodes. Four nerve fibers were analyzed by defining a model of the Hodgkin-Huxley type and conducting a simulation in Matlab R2021b. Anodic and cathodic threshold values were computed for each fiber and the performance of ST- and SV-positioned electrodes was compared. Moreover, the fibers were also simulated as degenerated fibers by cutting-off the dendrite. The outcomes of this thesis show lower threshold values for SV-positioned electrodes in non-degenerated fibers. In degenerated fibers higher currents are needed for excitation, especially for electrodes in the SV. This thesis also suggests mid-dendritic electrode position as the best electrode location. Although further research is needed, it can be stated that the SV is an adequate alternative for electrode insertion.
Global identification of bursicon-regulated genes in Drosophila melanogaster

description: Abstract Background Bursicon is a heterodimer neuropeptide responsible for regulating cuticle sclerotization and wing expansion in several insect species. Recent studies indicate that the action of bursicon is mediated by a specific G protein-coupled receptor DLGR2 and the cAMP/PKA signaling pathway. However, little is known regarding the genes that are regulated by bursicon. The identification of bursicon-regulated genes is the focus of this investigation. Results We used DNA microarray analysis to identify bursicon-regulated genes in neck-ligated flies (Drosophila melanogaster) that received recombinant bursicon (r-bursicon). Fifty four genes were found to be regulated by bursicon 1 h post r-bursicon injection, 52 being up-regulated and 2 down-regulated while 33 genes were influenced by r-bursicon 3 h post-injection (24 up-regulated and 9 down-regulated genes). Analysis of these genes by inference from the fly database http://flybase.bio.indiana.edu revealed that these genes encode proteins with diverse functions, including cell signaling, gene transcription, DNA/RNA binding, ion trafficking, proteolysis-peptidolysis, metabolism, cytoskeleton formation, immune response and cell-adhesion. Twenty eight genes randomly selected from the microarray-identified list were verified by real time PCR (qPCR) which supported the microarray data. Temporal response studies of 13 identified and verified genes by qPCR revealed that the temporal expression patterns of these genes are consistent with the microarray data. Conclusion Using r-bursicon, we identified 87 genes that are regulated by bursicon, 30 of which have no previously known function. Most importantly, all genes randomly selected from the microarray-identified list were verified by real time PCR. Temporal analysis of 13 verified genes revealed that the expression of these genes was indeed induced by bursicon and correlated well with the cuticle sclerotization process. The composite data suggest that these genes play important roles in regulating the cuticle sclerotization and wing expansion processes. The data obtained here will form the basis for future studies aimed at elucidating the exact mechanisms upstream from the secretion of bursicon and its binding to target cells.

description: L’ingresso del libro digitale nella scuola ripropone la questione più generale del manuale di studio. In attesa di ricerche che valutino l’efficacia del digitale nei confronti del cartaceo (o viceversa), è necessario recuperare un’attenzione alle finalità educative, alle motivazioni didattiche che hanno indotto, negli anni, a sostenere l’adozione del libro di testo, facendone uno degli strumenti privilegiati dei percorsi di formazione. Il testo digitale, fin dalla sua comparsa, ha sollevato una serie di questioni, insite nella sua stessa natura, che possono avere profonde ripercussioni sulla formazione. Ci obbliga, infatti, a riflettere su: l’evidenza di una pluralità di ‘letture’ possibili, riconducibili a diverse tipologie e forme testuali; il rapporto tra lettura e scrittura; la nuova idea di autorialità e di ‘narrazione’; la questione dei nuovi modelli di rappresentazione della conoscenza; il tema dei nuovi linguaggi e della formazione alla lettura digitale.
