Stuttering is a male-biased speech motor control disorder that lead to disruption in the rhythm of speech. The effect of sex on development of stuttering is well known; males are more susceptible to and less recovered from stuttering than female. Sex hormones have been studied as a main accused factor for this gender dependency of the disorder. The aim of this systematic review is to navigate the extent of previous research about the relationship of developmental stuttering and sex hormones. Toward these ends, a comprehensive, electronic review of past concepts regarding the relationship of stuttering with sex hormones and digit ratio as an indirect index for fetal testosterone exposure, in Scopus, Science Direct, PubMed, Medline, Embase, and Cochrane database was carried out to identify potential studies for the review. Inclusion criteria were original quantitative research, written in English, used human subjects and published from 2000 through 2020. Findings were mixed, although potential patterns were identified. There were methodological limitations such as small participant numbers, in the targeted population in this review research. The findings from this current study add to the growing body of evidence demonstrating that sex hormone have a significant association with stuttering.

Only a few birds besides domestic pigeons and poultry can be described as domesticated. Therefore, keeping a pet bird can be challenging, and the human-avian relationship will have a major influence on the quality of this cohabitation. Studies that focus on characterizing the owner-bird relationship generally use adapted cat/dog scales which may not identify its specific features. Following a sociological approach, a concept of human-animal relationship was developed leading to three types of human-animal relationship (impersonal, personal, and close personal). This concept was used to develop a 21-item owner-bird-relationship scale (OBRS). This scale was applied to measure the relationship between pet bird owners (or keepers) (n = 1,444) and their birds in an online survey performed in Germany. Factor analysis revealed that the relationship between owner and bird consisted of four dimensions: the tendency of the owner to anthropomorphize the bird; the social support the bird provides for the owner; the empathy, attentiveness, and respect of the owner toward the bird; and the relationship of the bird toward the owner. More than one quarter of the German bird owners of this sample showed an impersonal, half a personal, and less than a quarter a close personal relationship to their bird. The relationship varied with the socio-demographic characteristics of the owners, such as gender, marital status, and education. This scale supports more comprehensive quantitative research into the human-bird relationship in the broad field of human-animal studies including the psychology and sociology of animals as well as animal welfare and veterinary medicine.

Purpose: The research aim to clarify the relationship of brand loyalty: attitudinal and behavioral loyalty with the Malaysian purchase intention on pirated clothing and footwear in order to gain better understanding in developing advance countermeasure.Design/ Methodology/ Approach: A quantitative research is used to obtain the first hand information. 380 sets of personally- administrated questionnaires were distributed in Malaysia -Penang’s Batu Ferringhi Night Market. A variety of statistical analysis techniques were used.Findings: The findings suggested brand loyalty: attitudinal and behavioral have a significant relationship with the purchase intention of counterfeit products. Under the two brand loyalty concepts, the behavioral loyalty had a greater negative association with the consumer intention on counterfeit.  Practical implications: The paper provided in dept knowledge about the consumers motivation on counterfeit products and the information of marketing intelligence strategy-branding which available for the marketers and genuine manufacturers in better eradicate the counterfeit activities.Research Limitations: The paper was primarily focus on the counterfeit clothing and footwear. Although the focus and sample size is adequate and accepted but the generalizability of study may be limited and cannot consider as representative collectively for the whole of Malaysia and other pirated products. Secondly, the quantitative research used had limited the further insight of other unknown variables or factors that do not included.

Abstract- This study aims to determine the effect of brand popularity on brand loyalty, brand awareness, perceived quality and brand reputation among Etude House Indonesia users. Other objective of this study are to t he effect of brand loyalty, brand awareness, perceived quality and brand reputation on brand equity. The effect of brand equity on purchase intention To address the objectives of the study, a quantitative research design was implemented by distributing the questionaires to 360 Etude House Indonesia users and implementing the intruments that fulfilled the validity and reliability test requriements. The data were analyzed by SEM SmartPLS 3. The findings revealed that there was an effect of Brand popularity affects brand awareness, perceived quality, and brand reputation. Other results show that the counrry of brand origin affects brand loyalty, brand awareness and brand perceived quality. Also, Brand equity is determined by brand loyalty and brand reputation. While  Brand equity has a significant effect on purchase intention. In addition, brand equity also impacts on purchase intention. However, in this study the relationship of brand popularity to brand loyalty, the effect of country of brand origin on brand reputation, the effect of brand awareness on brand equity and the effect of perceived quality on brand equity is not supported in hypothesis testing. Keywords: Brand Popularity; Country of Brand Origin; Brand Loyalty, Brand Awareness; Perceived Quality; Brand Reputation; Brand Equity; Purchase Intention

<p>O objetivo com a presente pesquisa foi avaliar a relação da preocupação ambiental do consumidor com sua efetiva declaração de compra de produtos verdes no varejo. Orientado por uma linha de pesquisa que busca explicar o fato de o comportamento ter como precedente a intenção e não a atitude, foi avaliado se a preocupação dos consumidores com o meio ambiente está sendo convertidas em intenção de compra e posterior declaração de compra. O problema que orientou a pesquisa pode ser expresso pela seguinte questão: a preocupação ambiental está relacionada com a intenção de compra para se tornar compra declarada de produtos verdes no varejo? Para responder a essa questão e atender ao objetivo proposto, foi realizada uma pesquisa de natureza quantitativa por meio de um <em>survey</em> com 1.233 consumidores reais de quatro capitais brasileiras, avaliando-se a percepção que eles possuem de si mesmos e dos outros. A análise de dados foi feita utilizando-se a modelagem de equações estruturais por meio do <em>software</em> SmartPLS 3.0. Os resultados indicam que os consumidores pesquisados não demonstram relacionar diretamente sua preocupação ambiental com a compra declarada de produtos verdes, que revelou ser formada pela intenção de compra. Isso foi observado nas duas condições, quando os consumidores responderam sobre a sua percepção e sobre a dos outros (sociedade).</p><p>Palavras-chave: Consumo verde. Preocupação ambiental. Varejo.

Guided by a line of research that seeks to explain the fact that the behavior has as a precedent the intention and not the attitude was assessed to consumer concern about the environment and these are converted into purchase intent and purchase later statement. The problem oriented research can be expressed by the following question: Environmental concern is related to the purchase intention to become declared purchase of green products at retail? To resolve this matter and meet the proposed objective, a quantitative research through a survey with the 1233 actual consumers of four brazilian capitals assessing his perception as an individual was carried out and as he watches others. Data analysis was performed using the structural equation modeling through SmartPLS 3.0 software. The results indicate that consumers surveyed do not demonstrate directly relate their environmental concerns with the purchase declared for green products, which were shown to be formed by purchase intent. This perception takes place in the two conditions, when they respond on their perception and when they answer about how he observes others (society).</p><p>Keywords:<strong> </strong>Green consumption.

Measurements of drug occupancies using positron emission tomography (PET) can be biased if the radioligand concentration exceeds “tracer” levels. Negative bias would also arise in successive PET scans if clearance of the radioligand is slow, resulting in a carryover effect. We developed a method to (1) estimate the in vivo dissociation constant Kd of a radioligand from PET studies displaying a non-tracer carryover (NTCO) effect and (2) correct the NTCO bias in occupancy studies taking into account the plasma concentration of the radioligand and its in vivo Kd. This method was applied in a study of healthy human subjects with the histamine H3 receptor radioligand [11C]GSK189254 to measure the PK-occupancy relationship of the H3 antagonist PF-03654746. From three test/retest studies, [11C]GSK189254 Kd was estimated to be 9.5 ± 5.9 pM. Oral administration of 0.1 to 4 mg of PF-03654746 resulted in occupancy estimates of 71%–97% and 30%–93% at 3 and 24 h post-drug, respectively. NTCO correction adjusted the occupancy estimates by 0%–15%. Analysis of the relationship between corrected occupancies and PF-03654746 plasma levels indicated that PF-03654746 can fully occupy H3 binding sites ( ROmax = 100%), and its IC50 was estimated to be 0.144 ± 0.010 ng/mL. The uncorrected IC50 was 26% higher.

Purpose This study aims to propose a framework based on the main theoretical and empirical contributions present in the literature and articulate the main paths for future studies in knowledge-intensive entrepreneurship (KIE). Design/methodology/approach Using the systematic review method from a survey of 85 articles, related to the KIE focal issue, originated from the Web of Science, it was possible to exhaustively analyze the studies and to divide the theme into key categories. Findings The present research has raised the relationship of five categories to KIE conceptualizations; the data suggest that although the literature indicates a distancing from KIE research, there are multidisciplinary themes and approaches interlinked in the studies. Originality/value The systematic approach in the main theoretical and empirical contributions in KIE enabled us to relate five categories (entrepreneurs, innovation, internationalization, location and triple alliance), and finally, to understand the gaps suggested by the researchers.
