Firm Size, Age and Growth in South Africa

The relationship between a firm’s size, age and proportional growth rate is examined using multiple samples of South African firm-level data from the early to mid-2000s. The foundation of this study is Gibrat’s Law of Proportionate Effect (Gibrat, 1931), which states that a firm’s proportional growth rate is independent of its absolute size at the start of a given period. It is assumed that firm growth follows a random walk and, therefore, should not be affected by firm size. An implication of Gibrat’s Law of Proportionate Effect is that the firm size distribution is lognormal. However, based on both empirical and theoretical literature, this theory of firm growth has fallen out of favour and been replaced by the proposal that there is an inverse relationship between a firm’s proportional growth rate and both its size and age. Two questions are evaluated in this research using the samples of South African firms. The first is whether the firm size distribution is lognormal. If this is not the case then Gibrat’s Law of Proportionate Effect can be rejected. However, this approach cannot confirm that Gibrat’s theory is valid and will, therefore, be referred to in this paper as a partial test. It was shown that the log firm size distribution was not normal, but rather right-skewed with a Pareto distribution characterising the upper tail. Consequently, Gibrat’s Law of Proportionate Effect was rejected for the datasets of South African firms. This evidence is largely observational and does not explicitly assess the relationship between proportional growth rates and firm size. Therefore, the second question is whether Gibrat’s Law of Proportionate Effect holds. This was investigated by testing conditions derived from Gibrat’s Law of Proportionate Effect, the results of which can lead to either the rejection or acceptance of this proposition. This study extends Gibrat’s research in order to determine the relationship between firm age and proportional growth. Statistical methods, such as Ordinary Least Squares regressions, considering only firms that survived the period under consideration, were used. The results revealed that Gibrat’s Law of Proportionate Effect was invalid and there was a systematic tendency for the smaller, younger South African firms in the datasets to grow proportionally faster than the larger, older firms. This finding supports the view that firm growth is not entirely random

Client Perceptions of Quality and Choice at Static, Mobile Outreach, and Special Family Planning Day Services in 3 African Countries.

BACKGROUND: Use of long-acting reversible contraceptives (LARCs) has grown rapidly in the Democratic Republic of the Congo (DRC), Tanzania, and Uganda. Uptake of LARCs is particularly high during mobile outreach and special family planning day events. It is therefore important to examine client perceptions of and experiences with full, free, and informed choice (FFIC) in different service delivery modalities. METHODS: Between April and July 2015, we conducted a cross-sectional family planning client survey to assess FFIC and client satisfaction at static, mobile outreach, and special family planning day services in the DRC (n=9 sites), Tanzania (n=13), and Uganda (n=8). The study investigated clients' perceptions across 13 elements of FFIC, including measures of the quality of counseling and respondent satisfaction with services across the service delivery approaches. Composite FFIC scores were constructed and analyzed as the proportion of women who reported affirmatively to all elements and the mean score of positive responses. Satisfaction was assessed using a 4-point Likert scale. We used logistic regression to assess the association between the primary outcomes and mode of service delivery. RESULTS: In total, we interviewed 585 women (n=150 in Uganda, n=200 in Tanzania, and n=235 in the DRC). The large majority of clients in all countries and modalities received their method of choice. Clients of mobile outreach and special family planning days preferred LARCs and permanent methods, particularly implants, compared with clients at static services. Composite measures of FFIC were lower for mobile outreach than for static services in Tanzania among all family planning clients (odds ratio [OR]=0.5; P≤.001) and among LARC clients specifically (OR=0.5; P≤.01); no significant differences were found in the DRC or Uganda. A mean FFIC score among all family planning clients showed that clients in all modalities in all countries reported experiencing most elements of FFIC, with averages ranging from 4.8 to 6.1 of 7 elements. Among LARC clients specifically, mean scores ranged from 8.3 to 9.8 of 11 elements. Where greater proportions of clients experienced higher FFIC, greater proportions of clients also tended to report being "very satisfied" with aspects of services and counseling. CONCLUSIONS: The results underscore that special family planning days and mobile outreach services are important and viable ways to increase women's access to family planning services, notably to LARCs, but further attention to respecting and fulfilling clients' full, free, and informed choice across all service delivery modalities is required

First-trimester medical abortion with mifepristone 200 mg and misoprostol: a systematic review.

BACKGROUND: The dose of mifepristone approved by most government agencies for medical abortion is 600 mg. Our aim was to summarize extant data on the effectiveness and safety of regimens using the widely recommended lower mifepristone dose, 200 mg, followed by misoprostol in early pregnancy and to explore potential correlates of abortion failure. STUDY DESIGN: To identify eligible reports, we searched Medline, reviewed reference lists of published reports, and contacted experts to identify all prospective trials of any design of medical abortion using 200 mg mifepristone followed by misoprostol in women with viable pregnancies up to 63 days' gestation. Two authors independently extracted data from each study. We used logistic regression models to explore associations between 15 characteristics of the trial groups and, separately, the rates of medical abortion failure and of ongoing pregnancy. RESULTS: We identified 87 trials that collectively included 120 groups of women treated with a regimen of interest. Of the 47,283 treated subjects in these groups, abortion outcome data were reported for 45,528 (96%). Treatment failure occurred in 2,192 (4.8%) of these evaluable subjects. Ongoing pregnancy was reported in 1.1% (499/45,150) of the evaluable subjects in the 117 trial groups reporting this outcome. The risk of medical abortion failure was higher among trial groups in which at least 25% of subjects had gestational age >8 weeks, the specified interval between mifepristone and misoprostol was less than 24 h, the total misoprostol dose was 400 mcg (rather than higher), or the misoprostol was administered by the oral route (rather than by vaginal, buccal, or sublingual routes). Across all trials, 119 evaluable subjects (0.3%) were hospitalized, and 45 (0.1%) received blood transfusions. CONCLUSIONS: Early medical abortion with mifepristone 200 mg followed by misoprostol is highly effective and safe

Misoprostol: An emerging technology for women\u27s health—Report of a seminar

On May 7–8, 2001, the Population Council and the Center for Reproductive Health Research & Policy of the University of California, San Francisco, convened a technical seminar in New York City on the use of misoprostol for women’s health indications. The seminar was designed to provide a forum for researchers, providers, women’s health advocates, and educators to exchange information with the goal of advancing the potential of misoprostol to improve women’s health. Participants discussed the state of the art in research, examined current clinical use of misoprostol, and created strategies for the future. The first day focused on scientific and clinical aspects of misoprostol use. The second day’s discussion centered on the future of misoprostol for women’s health, including identifying priorities for research and the role of provider groups and women’s health and advocacy organizations in helping to ensure misoprostol’s continued, appropriate use. At the end of each session, the group had an opportunity to share ideas and discuss unanswered questions. This report covers the key issues raised by each speaker and highlights general areas of discussion among participants

Bullying By Teachers: Preventative Measures in Hogwarts

In our case study, the Battle of Hogwarts, we decided to address the problem of bullying by teachers against students in the forms of discrimination, indoctrination, and maltreatment of students and how that might result in negative educational outcomes such as a lack of self-esteem, racist beliefs, discrimination, and stress. Students who were bullied before, during, and after the battle may have long-lasting problems that resulted from such instances of mistreatment. For example, professors such as Snape and the Carrows discriminated against Muggle-born students like Hermione. During the take-over of Hogwarts by the Death Eaters, Defense Against the Dark Arts was changed to the Dark Arts, therefore indoctrinating the students to Voldemort’s belief system. Finally, the use of the Cruciatus curse on misbehaving students was a form of maltreatment perpetrated by professors of Hogwarts. After reviewing the literature, as the founders of the New Age of Hogwarts, we have proposed a multidimensional and holistic solution that we will describe after defining our subject matter

Trajectories of Alcohol Use and Consequences in College Women with and without Depressed Mood

College students with depressed mood face heightened risk for experiencing drinking-related negative consequences. However, few studies have examined prospective patterns of alcohol consequences among depressed students. In the present investigation, we assessed how first-year college women’s trajectories of heavy episodic drinking (HED) and alcohol consequences differed as a function of depressed mood at college entry. Participants were 233 heavy drinking incoming first-year college females (61% White) at a mid-sized west coast university. Participants completed an online baseline survey, attended a single brief group intervention session, and completed 1- and 6-month post-intervention follow-up surveys. Depressed mood, alcohol consumption, and alcohol consequences were assessed at each time point. We employed latent growth curve analyses. Females with depressed mood, versus without depressed mood, experienced greater levels of alcohol consequences overall, particularly during transitions to college. However, contrary to hypotheses, participants with depressed mood (vs. without) exhibited significantly steeper declining trends in consequences, controlling for treatment condition, age, race, and ethnicity, and despite stable drinking levels, depressed mood, and use of protective behaviors over time. Potential explanations and suggestions for future research are discussed

Misoprostol and teratogenicity: Reviewing the evidence

Misoprostol, a prostaglandin E1 analog marketed as Cytotec® for the prevention and treatment of gastric ulcers, is inexpensive and registered for use in over 80 countries. Many scientific articles show the preparation to be safe and effective for various reproductive health indications, including cervical softening and early pregnancy termination. Owing to the extensive body of published literature on these indications, misoprostol is now widely used for several reproductive health indications. The abortifacient properties of misoprostol are well known to medical professionals and frequently to the public. As noted in this meeting report, because the drug is available at low cost, many women have opted for self-administration of the method to terminate their pregnancies. The pharmaceutical industry and the public health community have raised the concern that if such an abortion attempt fails and the pregnancy results in a live birth, exposure of the fetus to misoprostol in utero could increase the risk of birth anomalies. The most extensively documented accounts of self-medication with misoprostol for induced abortion have come from Brazil, thus the case of Brazil provides a unique opportunity for studying the potential teratogenicity of misoprostol

Implementing the IUPUI Open Access Policy

This presentation was given at the 2016 Statewide Libraries Day Program at the IUPUI Campus Center. The event was held on May 20, 2016. This presentation took place from 9:00AM-9:50AM EST in Room 308 of the Campus Center. Speakers were Shannon Bahler, Lisa Calvert, and Jere Odell.On October 7, 2014, the IUPUI Faculty Council adopted an open access policy. The IUPUI faculty have retained their rights to the final manuscript of scholarly articles. The faculty have also given the library permission to archive these articles in the institutional repository, IUPUI ScholarWorks. As with most "Harvard-model" OA policies, faculty members are free to opt out at the article level without explanation. Likewise, waivers from the policy's rights retention clause are provided to any publisher that requires them. In this panel presentation we describe how the library has implemented this policy on the IUPUI campus. In specific we focus on four aspects of the policy implementation: 1) the outreach strategy; 2) the article identification/notification workflow; 3) the deposit workflow; and 4) the evolving role of liaisons in supporting the OA policy. Currently, the results of this multifaceted implementation strategy include: more than 1,400 new submissions to IUPUI ScholarWorks, increased compliance with federal public access policies, and more faculty interest in self-archiving
