The purpose of this paper is to examine hypothesized links between the Dana Center Mathematics Pathways’ (DCMP) Foundations of Mathematical Reasoning curriculum and the four hypothesized sources of self-efficacy. The sample of developmental mathematics students who were taught with a curriculum that incorporates active and collaborative learning reported increased ratings on social persuasions from the beginning to the end of the semester.
The study examines changes in the four sources of self-efficacy. Students completed a pre- and post-survey. Non-parametric methods were conducted to measure changes.
The paper provides empirical insights into changes in the four sources of self-efficacy with the implementation of a new curriculum in developmental mathematics classrooms. Students in the DCMP Foundation course increased their ratings on social persuasions and mastery experiences and decreased their ratings on physiological states. The largest proportion of variability in the four sources that was accounted for by course grade was mastery experiences followed by vicarious experiences, social persuasions and physiological states.
A control group was not included. Therefore, comparisons between students enrolled in the intervention course and a traditional course were not possible.
An implication of the study is that a curriculum that has an emphasis on face-to-face communication with collaborative learning activities might be linked to more positive measures of the sources of self-efficacy.
This paper fulfils a need to study how the implementation of an alternative curriculum in developmental mathematics classrooms can be linked to students’ self-efficacy.

This paper aims to introduce matching in propensity score analysis (PSA) as an alternative statistical approach for researchers looking to make causal inferences using intact groups.
An illustrative example demonstrated the varying results of analysis of variance, analysis of covariance and PSA on a heuristic data set. The three approaches were compared by results and violations of statistical assumptions.
Through the illustrative example, it is demonstrated how different statistical approaches can produce varied results. Only PSA mitigated pre-existing group differences without violating the assumption of independence.
This paper attempts to answer calls in the literature for more robust statistical methodologies to better inform human resource development practice and theory.
The enormous improvement in child health in this country—in infant mortality and morbidity, in physical growth and well‐being, are self‐evident. Not only do we see the physical improvement in our children, but it strikes visitors from overseas more forcibly, and there can be few other countries in the world which can boast such swarms of healthy, vigorous children. If this was preventive medicine's only success, it would be worth many times over the money spent on this branch of the National Health Service, which is little enough in all conscience: about £20 millions a year compared with over £400 millions for curative medicine. Can any of the undoubted great and dramatic advances of the latter match the far‐reaching effects of this one achievement of preventive medicine?

Relatively limited attention has been paid to the academic needs of students with emotional and behavioral difficulties. Effective interventions are needed to support these students academically, behaviorally, and socially. The purpose of the concurrent studies reported here was to investigate the effectiveness of academic support in writing for fourth- and fifth-grade students (six boys, two girls) and second- and third-grade students (seven boys, one girl) with writing and behavioral difficulties. The Self-Regulated Strategy Development (SRSD) approach was implemented as a tier-2 intervention within a comprehensive, integrated three-tiered model of prevention including academic-, behavioral-, and social-skills components. Students learned an on-demand writing strategy for their state writing-competency test. Dependent measures included number of story writing elements, total number of words written, and writing quality. Fourth- and fifth-grade students who completed the intervention improved in total number of story elements. There were mixed results for the total number of words written and writing quality. Second- and third-grade students did not improve their total number of story elements, total words written, or writing quality. Students in both studies scored the intervention favorably, while there were mixed reactions from teachers. Findings, limitations, and suggestions for future research are discussed. Implications for the construct of evidence-based practice (EBP) are also explored, including concerns regarding frequent assessment of writing throughout intervention regardless of stage of instruction in the SRSD model.

The Chinese Professional Baseball League (CPBL) experienced a rapid decline in attendance after the mid 1990s. In this study, market demand analysis is used to discover the causes of variation in CPBL attendance from 1990 to 2008. The ordinary least squares (OLS) is employed for model estimation. From this model, empirical evidence reveals that a homogenous sport substitute, Taiwan Major League (TML), the Major League Baseball (MLB) effect and game-fixing scandals in CPBL negatively influence CPBL attendance. Additionally, real income is found to negatively affect CPBL attendance, making CPBL games an inferior product. The proposed model accounts for approximately 91% of variation in CPBL attendance between 1990 and 2008.

The food standards of the Indiana State Board of Health, which appear on another page, show that it is quite possible to lay down official definitions of various articles of food; and a study of these regulations may be of assistance to those authorities who are striving to arrive at some form of order out of the chaos which at present exists in this country in matters relating to food standards. With reference to milk, it will be seen that not only is the question of composition dealt with, but strict directions are given that milk derived from a cow which can in any way be considered as diseased is regarded as impure, and must therefore, says the Board, be considered as adulterated. In regard to butter and margarine, limits are given for the total amount of fat—which must consist entirely of milk‐fat in the case of the former substance—water, and salt; and not only are all preservatives forbidden, but the colouring matters are restricted, only certain vegetable colouring matters and some few coal‐tar colours being permitted. All cheese containing less than 10 per cent, of fat derived from milk must be plainly labelled as “ skim‐milk cheese”; and if it contains fat other than milk‐fat, it must be described as “ filled cheese.” Some exception is taken to the use of preservatives in cheese, inasmuch as it appears that cheese may contain a preservative if the name of such preservative is duly notified upon the label ; and the rules for the colouring of cheese are the same as those which apply to butter and margarine. All articles of food containing preservatives are considered as adulterated unless the package bears a label, printed in plain type and quite visible to the purchaser, stating that a preservative is present, and also giving the name of the preservative which has been used. Articles of confectionery must not contain any ingredient deleterious to health, such as terra alba, barytes, talc, or other mineral substance, nor may they contain poisonous colours or flavours.
