The World Wide Web (WWW) is so often used as a way of interacting with the Internet that many people mistakenly confuse the two, referring to the Internet as the Web and vice versa. Of course, the Internet and its native applications predate the development of the WWW protocols by decades. Still, given the overwhelming amount of available Internet bandwidth now devoted to the transmission of web pages, there is no doubt that the WWW is the interface of choice for most users of the world\u27s most pervasive computer network. The WWW is not the Internet, but there can be no doubt that it is the Internet\u27s first killer app

Digital Financial Services and Strategic Financial Management: Financial Services Firms and Microenterprises in African Markets

This study highlights the impact of digital financial services as enhancing the capacity of development goals as well as social sustainability. The selected emerging markets are Ghanaian financial service providers (FSP)s and microenterprise customers (CME)s, where we examine how “Ubuntu”, an African philosophy of humanism, legitimizes spaces for a more democratic, egalitarian, and ethical engagement of human beings. This study adopts a grounded theory methodology for investigation of the phenomena with a sample size of 70 relationship managers. The findings further existing sustainability literature pertaining to social sustainability and consumer wellbeing. We contribute to theory by presenting a psychological perspective which be leveraged for digital financial services branding to expand usage within communal systems. This leverage of Ubuntu becomes especially relevant when there is the need to compensate for deficits in weak business infrastructures in low-income but expanding markets. Our study highlights digital financial services can be used to improve the emotional and psychological consumer wellbeing and to strengthen business relationships, meeting joint goals of market share expansion, brand image enhancement and profitability. This perspective also contributes to social sustainability on a global scale since the Western world depends on quality products from emerging markets

ALPCAH: Sample-wise Heteroscedastic PCA with Tail Singular Value Regularization

Principal component analysis (PCA) is a key tool in the field of data dimensionality reduction that is useful for various data science problems. However, many applications involve heterogeneous data that varies in quality due to noise characteristics associated with different sources of the data. Methods that deal with this mixed dataset are known as heteroscedastic methods. Current methods like HePPCAT make Gaussian assumptions of the basis coefficients that may not hold in practice. Other methods such as Weighted PCA (WPCA) assume the noise variances are known, which may be difficult to know in practice. This paper develops a PCA method that can estimate the sample-wise noise variances and use this information in the model to improve the estimate of the subspace basis associated with the low-rank structure of the data. This is done without distributional assumptions of the low-rank component and without assuming the noise variances are known. Simulations show the effectiveness of accounting for such heteroscedasticity in the data, the benefits of using such a method with all of the data versus retaining only good data, and comparisons are made against other PCA methods established in the literature like PCA, Robust PCA (RPCA), and HePPCAT.

Evaluation of the Short Grit Scale (GRIT-S) with Latinx College Students

In the current study, the psychometric properties of a measure of psychological grit among 344 Latinx college students was investigated. Researchers used confirmatory factor analysis to validate a previously identified two-factor model of the Short Grit Scale (Grit-S). Internal consistency was acceptable as measured by coefficient alpha. A two-factor model of Grit-S had a good model fit with the data. A discussion regarding the importance of these findings is provided and implications for counselors and researchers are offered

Development of Perceived School Counselor Support Scale: Based on the ASCA Mindsets and Behaviors

This study presents a culturally and psychometrically sound instrument of perceived school counselor support among Turkish high school students. The study has been framed using American School Counseling Association’s Mindsets and Behaviors for Students Success Model to create a valuable instrument that measures students’ perceptions of their school counselors’ support in a different culture, society, and education system. The results of this study supported the theoretical based Perceived School Counselor Support Scale long and short forms providing initial and strong evidence based on internal structure and relations to other variables. Internal consistency estimates on subscales ranged from good to strong

Declines in prevalence of adolescent substance use disorders and delinquent behaviors in the USA: A unitary trend?

AbstractBackgroundDownward trends in a number of adolescent risk behaviors including violence, crime, and drug use have been observed in the USA in recent years. It is unknown whether these are separate trends or whether they might relate to a general reduction in propensity to engage in such behaviors. Our objectives were to quantify trends in substance use disorders (SUDs) and delinquent behaviors over the 2003–2014 period and to determine whether they might reflect a single trend in an Externalizing-like trait.MethodsWe analyzed data from 12 to 17 year old participants from the National Survey on Drug Use and Health, a representative survey of the household dwelling population of the USA, across the 2003–2014 period (N = 210 599). Outcomes included past-year prevalence of six categories of substance use disorder and six categories of delinquent behavior.ResultsTrend analysis suggested a net decline of 49% in mean number of SUDs and a 34% decline in delinquent behaviors over the 12-year period. Item Response Theory models were consistent with the interpretation that declines in each set of outcomes could be attributed to changes in mean levels of a latent, Externalizing-like trait.ConclusionsOur findings suggest that declines in SUDs and some delinquent behaviors reflect a single trend related to an Externalizing-like trait. Identifying the factors contributing to this trend may facilitate continued improvement across a spectrum of adolescent risk behaviors.</jats:sec

“I just want to be skinny.”: A content analysis of tweets expressing eating disorder symptoms

There is increasing concern about online communities that promote eating disorder (ED) behaviors through messages and/or images that encourage a “thin ideal” (i.e., promotion of thinness as attractive) and harmful weight loss/weight control practices. The purpose of this paper is to assess the content of body image and ED-related content on Twitter and provide a deeper understanding of EDs that may be used for future studies and online-based interventions. Tweets containing ED or body image-related keywords were collected from January 1-January 31, 2015 (N = 28,642). A random sample (n = 3000) was assessed for expressions of behaviors that align with subscales of the Eating Disorder Examination (EDE) 16.0. Demographic characteristics were inferred using a social media analytics company. The comprehensive research that we conducted indicated that 2,584 of the 3,000 tweets were ED-related; 65% expressed a preoccupation with body shape, 13% displayed issues related to food/eating/calories, and 4% expressed placing a high level of importance on body weight. Most tweets were sent by girls (90%) who were ≤19 years old (77%). Our findings stress a need to better understand if and how ED-related content on social media can be used for targeting prevention and intervention messages towards those who are in-need and could potentially benefit from these efforts.</div

Factorial Validity of Teacher and School Counselor Support Scales in Latina/o Students

In the current study, we investigated the psychometric properties of two meaningful measures of support from teachers and school counselors among Latina/o students. Examining factorial stability with diverse populations is important to make sure that measures provide valid information about constructs of teacher or counselor support. While researchers have provided evidence of reliability (i.e., consistency), no study has examined validity (e.g., accuracy) of Teacher Support Scale Revised (TSSR) with Latina/o students. Confirmatory and exploratory factor analyses (CFA and EFA) methods were used to evaluate structural validity of the TSSR and School Counselor Support Scale (SCSS). Two different models of the TSSR were analyzed. Findings from multiple CFAs showed that five-factor 22-item of the TSSR had an acceptable model fit. A parallel analysis and EFA were run to determine the factorial structure of the SCSS. Findings indicated that the SCSS had three factors explaining 68% of the variance in the model. The results and implications for research and practice in Latina/o students were discussed
