Improved butterfly optimisation algorithm based on guiding weight and population restart

ABSTRACT Butterfly Optimisation Algorithm (BOA) is a kind of meta-heuristic swarm intelligence algorithm based on butterfly foraging strategy, but it still needs to be improved in the aspects of convergence speed and accuracy when solving with high-dimensional optimisation problems. In this paper, an improved butterfly optimisation algorithm is proposed, in which guiding weight and population restart strategy are applied to the original algorithm. By adding guiding weight to the global search equation, the convergence speed and accuracy of the algorithm are improved, and the possibility of jumping out of the local optimal solution is increased by the population restart strategy. In order to verify the performance of the proposed algorithm, 24 benchmark functions commonly used for optimisation algorithm experiments are applied in this paper, including 12 unimodal functions and 12 multimodal functions. Experimental results show that the proposed algorithm improves the convergence speed, accuracy and the ability to jump out of the local optimal solution.
Involuntary and voluntary demotion: employee reactions and outcomes

ABSTRACT Demotion has received little attention from scholars and practitioners alike. The purpose of this study was to assess empirically the reaction to, and outcomes of, both involuntary and voluntary demotion. Drawing on 49 semi-structured in-depth interviews with 28 involuntarily demoted workers and 21 voluntarily demoted workers, we develop a conceptual model using organizational justice theory and person-job fit of the reaction to and outcomes of demotion. We show that involuntarily demoted individuals might react by expressing turnover intentions and lower motivation and commitment, indicating that the demotee’s reaction is related to perceptions of fairness. Voluntary demotion is related to a better work-life balance, greater satisfaction, less stress and burnout and is perceived to be a viable phased retirement option by older workers. In addition, the findings highlight the role of demotion-related stigma, status loss, identity threat, and age in the way employees react to the experience of demotion.
Optimization of bending and shear rigidities of woven fabrics using desirability function

Abstract Banding and shear properties influence the drape and handle characteristics of woven fabrics. As bending and shear rigidities of woven fabrics generally have high degree of association, it is difficult to design a woven fabric having low bending rigidity and high shear rigidity or vice versa. This paper deals with the optimization of bending and shear rigidities of woven fabrics using the desirability function approach. Low stress mechanical properties such as bending rigidity and shear rigidity have been combined to represent ‘the overall desirability’ which is varying from 0 to 1. The overall desirability has been maximized against the target values of shear and bending rigidities. It was possible to attain overall desirability of 0.684 resulting from individual desirability of 0.662 and 0.707 for banding and shear rigidities, respectively. Experimental validation confirms that the applied method can be effectively used to optimize the woven fabric mechanical properties at low stress region.
Keeping it raw on the ‘gram: Authenticity, relatability and digital intimacy in fitness cultures on Instagram

This article builds on a growing body of research on social media and authenticity through examining practices of ‘keeping it raw’ in fitness cultures on Instagram. Such practices include posting unedited or ‘realistic’ visuals of the body, storying the everyday and ‘real talk’ about topics such as mental health and body image. Drawing on empirical findings from my research with 21 Australian women aged 20–35 who use Instagram to post and engage with fitness inspiration – fitspo – content, I specifically trace how enactments of ‘raw’ cultivate digital intimacies between Instagram users. Here, I take up a feminist new materialist approach to consider how various body parts, objects, platform functionalities and discourses come together to create affective encounters between my participants and other Instagram users. The contribution of this article lies in attending to the work that raw does, to what end and for whom.
Antibacterial activity of oxytetracycline on microbial ecology of Nile tilapia (
 Oreochromis niloticus
 ) gastrointestinal tract under laboratory condition

The antibacterial effect of oxytetracycline (OTC) on bacterial load, pathogen and possible development of antibiotic resistance in intestinal flora of apparently healthy Nile tilapia (Oreochromis niloticus) was investigated under laboratory condition. OTC, a broad spectrum approved antibiotic widely used in aquaculture, was fed to Nile tilapia through medicated diet at a rate of 2 g/ kg of feed for consecutive 7 days in treatment 1 (T₁) and 30 days in treatment 2 (T₂). Changes in physico‐chemical parameters of water were also recorded where pH and dissolved oxygen influenced bacterial load and coliform count respectively. At the start of the experiment, initial bacterial load in fish intestine was 1.61 ± 2.25 × 10¹⁰ cfu/g, which after OTC treatment decreased significantly (p < .05) to 3.06 ± 2.08 × 10⁸ cfu/g on day 7 and 3.45 ± 4.46 × 10⁷ cfu/g on day 30 when compared with the control group. Among the 10 bacterial genera identified in the intestine, 4 potential public health concern bacteria viz., Salmonella, Escherichia, Enterobacter and Staphylococcaus were predominant. There was a sharp increase in bacterial load on day 18 in T₂ that may be attributed to the development of antibiotic resistance in intestinal bacteria. Antibiotic susceptibility test for isolates against seven antibiotics: amoxycillin, ciprofloxacin, co‐trimoxazole, erythromycin, gentamicin, nitrofurantoin and tetracycline using disc diffusion method revealed significantly increased resistance of Gram‐negative rods (p < .05) that possibly caused increased frequency of OTC‐resistant microorganisms. In conclusion, short‐ and long‐term exposure to OTC treatment affected the distribution of bacterial genera including pathogens in the Nile tilapia gastrointestinal tract and concomitantly influenced their antimicrobial resistance.
Four-Features Evaluation of Text to Speech Systems for Three Social Robots

The success of social robotics is directly linked to their ability of interacting with people. Humans possess verbal and non-verbal communication skills, and, therefore, both are essential for social robots to get a natural human–robot interaction. This work focuses on the first of them since the majority of social robots implement an interaction system endowed with verbal capacities. In order to do this implementation, we must equip social robots with an artificial voice system. In robotics, a Text to Speech (TTS) system is the most common speech synthesizer technique. The performance of a speech synthesizer is mainly evaluated by its similarity to the human voice in relation to its intelligibility and expressiveness. In this paper, we present a comparative study of eight off-the-shelf TTS systems used in social robots. In order to carry out the study, 125 participants evaluated the performance of the following TTS systems: Google, Microsoft, Ivona, Loquendo, Espeak, Pico, AT&T, and Nuance. The evaluation was performed after observing videos where a social robot communicates verbally using one TTS system. The participants completed a questionnaire to rate each TTS system in relation to four features: intelligibility, expressiveness, artificiality, and suitability. In this study, four research questions were posed to determine whether it is possible to present a ranking of TTS systems in relation to each evaluated feature, or, on the contrary, there are no significant differences between them. Our study shows that participants found differences between the TTS systems evaluated in terms of intelligibility, expressiveness, and artificiality. The experiments also indicated that there was a relationship between the physical appearance of the robots (embodiment) and the suitability of TTS systems.
A new species of Noccaea (Brassicaceae) from central Anatolia

Noccaea atila-ocakii is described as a new species from Eskisehir, Turkey. Morphologically, it is similar to N. antitaurica and N. lilacina, but it is easily distinguished by several morphological characters, including the size of its basal leaves, shape of its cauline leaves and fruit, length of its style, number of ovules, etc. Phylogenetic relationships, based on the nuclear-encoded ribosomal internal transcribed spacer (ITS) region, within the genus are shown. Molecular data reveal that new species clearly differs from N. antitaurica and N. lilacina. Paraphyletic taxa in the phylogenetic tree also indicate that the generic circumscription of Noccaea by Al-Shehbaz is more convenient compared with previous delimitations of this genus. Diagnostic characters, a detailed description, and photographs of the new species are given; the IUCN Red List category and observations on the ecology of the populations are noted; and the distribution map of the new species and its closely related species in Turkey are presented.
Changes in social groups across reintroductions and effects on post‐release survival

Reintroductions, essential to many conservation programmes, disrupt both abiotic and social environments. Despite growing recognition that social connections in animals might alter survival (e.g. social transmission of foraging skills, or transmission of disease), there has thus far been little focus on the consequences of social disruption during reintroductions. Here we investigate if moving familiar social groups may help a threatened species to adjust to its new environment and increase post‐release survival. For a reintroduction of 40 juvenile hihi Notiomystis cincta (a threatened New Zealand passerine), we observed social groups before and after translocation to a new site and used social network analysis to study three levels of social change: overall group structure, network associations and individual sociality. We also tested alternate translocation strategies where birds were kept temporarily in aviaries in either a familiar group, or where their prior association was mixed. Although social structure remained similar among juveniles that remained at the source site, we detected significant changes in translocated birds at both the group‐ and individual‐ level post‐release. However, our holding treatments did not affect these social bonds so we remain unable to maintain or manipulate social groups during translocation. Crucially, there was a small tendency for translocated juveniles that gained more associates during re‐assortment of social groups to be more likely to survive their first year post‐release. We suggest that prior sociality may not be important during translocations, but rather individuals that are most able to adapt and form associations at a new site are most likely to be the surviving founders of reintroduced populations.
Predicting stress urinary incontinence in primiparous women who underwent vaginal delivery using a classification tree approach.

Hypothesis / aims of study Vaginal delivery (VD) has been recognized as potentially traumatic to the pelvic floor (PF) and may lead to stress urinary incontinence (SUI) [1]. Studies have been conducted to identify factors that predict SUI after VD. Important to note is that these factors do not occur in isolation, therefore the investigation of the association between them offers results with higher external validity, giving support to the clinical decision making process. The aim of this study was to investigate predictive factors for SUI in primiparous women who underwent VD using a statistical approach relevant to the clinical practice.
A Study of Children’s Physical Self-Perceptions Using an Adapted Physical Self-Perception Profile Questionnaire

This project was a study of the validity and reliability of adapted versions of Fox and Corbin’s (10) Physical Self-Perception Profile (PSPP) and Perceived Importance Profile (PIP) for use with seventh- and eight-grade students. The Children’s PSPP and PIP (C-PSPP and C-PIP) questionnaires were completed by 505 students. Results supported the reliability and the construct and concurrent validity of the C-PSPP scales. Factorial validity of the C-PIP was not demonstrated. Similar to Fox and Corbin’s (10) results, regression analysis revealed that a large proportion of the variance in general physical selfworth (PSW) was explained by the C-PSPP scales. The hypothesis that PSW mediates between general self-worth (GSW) and the four C-PSPP scales in a hierarchical arrangement was also supported. Failure to psychologically discount the importance of perceived incompetence in specific areas impacted global self-worth. Correlations with physical fitness test scores provided evidence of concurrent validity of the C.
NONLINEAR DYNAMIC ANALYSIS PROCEDURE WITH LIMITED NUMBER OF ANALYSES AND SCALING

Incremental dynamic analysis (IDA) is the most frequently used non-linear dynamic analysis procedure for seismic fragility assessment. Nevertheless, its implementation involves complications such as heavy computational burden and potential bias in the results due to excessive scaling of the ground motion records. Cloud Analysis is an alternative nonlinear dynamic analysis procedure based on the structural response to as-recorded ground motions. Cloud Analysis does not suffer from the above-mentioned complications for IDA; however, it may lead to results that reveal too much sensitivity to the choice of the ground motion records. A novel hybrid nonlinear dynamic analysis procedure referred to as “Cloud to IDA” exploits the predictive capacity provided by Cloud Analysis to perform Incremental Dynamic Analysis (IDA) in a very efficient manner and with very little amount of scaling --without any loss of accuracy with respect to IDA. The procedure adopts as a systemic damage measure the critical demand to capacity ratio (DCR). This facilitates to a great extent identification of the intensity values at the onset of the limit state (where DCR is equal to unity by definition) and thereby the implementation of the IDA procedure. Cloud to IDA procedure is applied to the transverse perimeter frame of an older seven-storey reinforced concrete building in Van Nuys, US. This frame is modeled in OpenSees with fiber sections considering flexural-shearaxial interactions and bar slip due to fixed-end rotations. The proposed Cloud to IDA leads to results that are identical to IDA, when the same set of records are used. All of this is possible with a number of analyses that is sensibly lower with respect to IDA.
CLINICAL CASE SEMINAR Infertility Caused by hCG Autoantibody

An anti-hCG autoantibody was found in a patient with a 9-yr history of secondary infertility. Although the patient had regular menstrual cycles, had conceived spontaneously, and had good hormonal and follicular responses to gonadotropic stimulation regimens during the in vitro fertilization work-up, she presented with apparent recurrent pregnancy loss associated with prolonged raised hCG levels. Initially the presence of a high mol wt hCG complex was demonstrated in the serum by gel chromatography. The binding of [ 125 I]recombinant hCG to a serum sample and subsequently to the affinity-purified IgG from the same sample revealed the presence of an hCG antibody. The antiserum was shown to be specific, with a low affinity (Ka, 1.4 10 6 liters/mol), but a high capacity (418 nmol/ liter), for hCG. Cross-reaction with recombinant human FSH, recombinant human LH, hCG, and hCG were low (<0.019%, 0.021%, 0.039%, and 0.006%, respectively). In addition, heatinactivated serum and the affinity-purified IgG were shown to inhibit the action of hCG in an in vitro bioassay. We suggest that the persisting titer of the antibody to be responsible for the patient’s infertility. (J Clin Endocrinol Metab 87: 993–997, 2002)
Endometriosis and Infertility: The Impact on Quality of Life and Mental Health

Endometriosis is one of the most common gynaecological diseases and has an incidence of about 6%-10% in women of reproductive age. It has been estimated that 50% of women with fertility problems have endometriosis. The management of infertility associated with endometriosis is difficult and controversial and it is important to provide a multidisciplinary approach in order to reduce the impact of these diseases on psychological and emotive well-being of affected women, as much as possible.
Roles of egos’ and siblings’ perceptions of maternal favoritism in adult children’s depressive symptoms: A within-family network approach

Abstract It is well documented that intergenerational ties play important roles in adults’ well-being. However, most studies focus on the impact of individuals’ own perceptions of their ties without considering whether family members’ assessments of these ties affect well-being. We address this question using data from 296 adult children nested within 95 later-life families in which all offspring were interviewed. Applying a mixed-method within-family approach, we explored whether the effect of perceived maternal favoritism on depressive symptoms was increased when siblings shared ego’s perceptions. Multilevel regression analyses revealed that ego’s own perceptions predicted depressive symptoms, but only among daughters. Siblings’ perceptions that egos were most close to mothers did not affect the well-being of daughters or sons. Qualitative analyses suggested that differential effects of perceived favoritism by gender reflected differences in the meaning sons and daughters associated with being favored children. Favored daughters were more likely than favored sons to report that they were emotional caregivers to their mothers; this pattern was especially strong when siblings reinforced egos’ perceptions of being “best suited” for this role. These findings emphasize the salience of egos’ own perceptions, relative to those of family network members, in shaping role embracement and psychological well-being, especially among women.
Robot Multimodal Object Perception and Recognition: Synthetic Maturation of Sensorimotor Learning in Embodied Systems

It is known that during early infancy, humans experience many physical and cognitive changes that shape their learning and refine their understanding of objects in the world. With the extended arm being one of the very first objects they familiarize, infants undergo a series of developmental stages that progressively facilitate physical interactions, enrich sensory information, and develop the skills to learn and recognize. Drawing inspiration from infancy, this article deals with the modeling of an open-ended learning mechanism for embodied agents that considers the cumulative and increasing complexity of physical interactions with the world. The proposed system achieves object perception and recognition as the agent (i.e., a humanoid robot) matures, experiences changes to its visual capabilities, develops sensorimotor control, and interacts with objects within its reach. The reported findings demonstrate the critical role of developing vision on the effectiveness of object learning and recognition and the importance of reaching and grasping in solving visually elicited ambiguities. Impediments caused by the interdependency of parallel components responsible for the agent’s physical and cognitive functionalities are exposed, demonstrating an interesting phase transition in utilizing object perceptions for recognition.
Influence of Solar Reflectance and Renewable Energies on Residential Heating and Cooling Demand in Sustainable Architecture: A Case Study in Different Climate Zones in Spain Considering Their Urban Contexts

In this research work, energy simulation was used as a forecasting tool in architectural design. It includes the study of a multi-family residential building in five different climate zones of Spain, i.e., A4 (very hot climate zones), B4 (hot climate zones), C4 (moderate climate zones), D3 (cold climate zones), and E1 (very cold climate zones). The authors accomplished a sensitivity analysis in order to identify the influence of passive strategies (i.e., with regard to solar reflectance) and renewable energy (i.e., with regard to aerothermal energy) on indoor temperatures and energy demands. The increment in indoor temperatures depends on the neighboring buildings so that effect of urban contexts as a source of protection against sunlight is also considered. The increment in the albedo (i.e., the solar reflectance) of the facade during the winter period produces little differences in indoor operative temperatures. On the contrary, during the summer period, it produces large temperature differences. Therefore, it is shown that colors significantly reduce temperatures from 1.24 to 3.04 °C, which means considerable annual energy savings. This research demonstrates that solar reflectance can reduce the air indoor operative temperature down to 4.16 °C during the month of May in the coldest climate zones. As a result of the simulations, it is noted that the coldest climate zones are influenced to a greater extent by the inclusion of their urban contexts in the simulations. However, the heating demand, without considering it, becomes lower. Therefore, ignoring the urban context produces important errors in the heating analysis (12.2% in the coldest climate zones) and also in the cooling analysis (39% in the hottest climate zones). Finally, the use of renewable energy in the configuration of a model with a high urban canyon (Hc), as well as with an east–west building orientation and a low albedo produces a difference of around 76% in the cooling costs within the hottest climate zones and around 73% in the heating costs within the coldest climate zones. The results of this study can be applied as a guideline in early architectural design.
