The ‘U-turn’: Business confi dence in a Karoo town

Business confidence helps explain the sentiments that business owners or managers have towards current and future business conditions. This article compares several ways of measuring business confi dence. Business confi dence is mostly surveyed at the level of the nation-state rather than at the level of municipalities or towns. This article provides a methodology for business-confi dence surveys at the local level. This approach has been piloted in the town of Beaufort West in the Karoo area of South Africa. There are plans for a new uranium mine near Beaufort West, and the researchers speculate on its impact on the broader local business confi dence

An aspect of language for academic purposes in secondary education: complex sentence comprehension by learners in an integrated Gauteng school

Language for academic purposes is an important concept, not always recognised and developed within the education system. The ability to use language for learning can be diff icult for individuals who are educated in a second language. They are required to master complex concepts in a language they are still acquiring. We aimed to discover how secondary school learners performed on an aspect of academic language: complex sentence comprehension. A group of 464 adolescent participants’ performance on the grammatical understanding subtest of the Test of Adolescent Language was analysed in relation to their status as first or second language English learners, their grade, gender, literacyexperiences, preferred modality of learning, and other factors deemed to influence language acquisition in modern society. The results indicated that the majority of learners achieved within the average range. There were significant differences between the male and female participants and the junior phase ESL males achieved the lowest scores. It was concluded that it may take 8–9 years of formal schooling for some individuals to acquire the requisite academic language proficiency, particularly if they are learning in their second language. This has important implications for the teaching and assessment of second language learners

Mysterious circles in the Namib Desert

AbstractThere is currently still no scientifically sound explanation as to the origin of the so-called “fairy circles” in the Namib. An in situ experiment was conducted in the NamibRand Nature Reserve to test the latest hypothesis that the circles are the result of a semi-volatile gas that inhibits plant growth. Stipagrostis ciliata grass plants were planted in containers filled with soil from the circle or from outside the circle. Some containers were sealed at the bottom, to prevent any gases from entering from below, while others were left open. Containers were placed both inside the circle as well as outside the circle. The origin of the soil, i.e. whether it came from inside or outside the circles, did not affect the performance of the plants when they were growing in the same position and container type. All plants growing outside the circle, irrespective of the origin of the soil or the container type, performed better than those growing inside the circle. It is concluded that there is a factor inhibiting plant growth in the circle and that this factor could possibly be a semi-volatile gas, because growth was more negatively affected in the open containers than in the sealed containers

Transitioning of final year nursing students to professional nurses: A best practice guideline

Abstract Background. The period of transition from student nurse to professional nurse in various healthcare contexts can be challenging. No best practice guideline could be found optimizing the transition of final year nursing students to professional nurses in the South African Military Health Service (SAMHS).Methods. A draft guideline was developed based on data from interviews with students and professional nurses, and an integrative literature review including guidelines on the transition of final year nursing students to professional nurses (content), using the AGREEII instrument (format), which was piloted using expert panel reviews.Results. The guideline covers four areas: support for new graduates, providing socialization and belonging, enhancing a positive clinical learning environment and ensuring retention of newly qualified professional nurses.Conclusion. The guideline provides a guide to best practices which can be used by nurse educators and managers but requires implementation to determine its impact on a successful transition period.

Accompaniment needs of nursing students related to the dying patient

Nurse educators are responsible for accompanying students towards becoming capable, competent professional nurses who are a credit to themselves, their patients, colleagues and profession. Student nurses need, therefore, to be taught to render comprehensive nursing care to patients in all stages of their lives, including when they are dying. Being confronted with human suffering and death is challenging and traumatic. Those exposed to such events on a daily basis need to have a solid foundation of self preservation to see past the pain of suffering and to bring light and hope to those in need. A young student nurse will only experience positive growth and development in these circumstances if she is also cared for and guided with understanding. The researcher utilized a qualitative, explorative, descriptive and contextual design based on the phenomenological approach to enquiry. The following question was asked at the beginning of each unstructured phenomenological interview: “How was if for you to care for a dying or deceased patient?” The central theme identified that student nurses experience turmoil in their different relationships in their accompaniment of the dying patient. Guidelines based on the central theme and sub-themes that emerged from raw data, as well as literature, are offered as strategies to promote/enhance optimal accompaniment of student nurses caring for the dying patient

Pulmonary haemosiderosis

A 2 year 9 month old girl was referred to Steve Biko Academic Hospital (SBAH) from Tshwane District Hospital (TDH) on the 31st of October 2014, with an initial diagnosis of a community acquired pneumonia. Her initial chest x-ray is depicted in Figure 1 showing non-specific interstitial changes with involvement of both lung fields.http://www.allergysa.org/journal.htmhb201

Performance indicators that discriminate winning and losing in elite men’s and women’s Rugby Union

This study aimed to identify performance indicators that discriminate winning and losing in elite men’s and women’s Rugby Union during the latest World Cup competitions. The knockout stages of the men’s 2015 Rugby World Cup (n = 8) and women’s 2014 Rugby World Cup (n = 8) were compared. Findings suggest that in the men’s game, winning teams kicked a greater percentage of possession in the opposition 22–50 m with a view to gaining territory and pressuring the opposition (winners = 16%, losers = 7%). In the women’s game successful teams adopted a more possession-driven attacking approach in this area of the pitch. Successful women’s teams appear more willing to attack with ball in hand following a kick receipt and adopt a more expansive game through attacking with wider carries in the outside channels. The percentage of lineouts won on the opposition ball was found to be an important performance indicator that discriminates winners and losers, regardless of sex (winners = 18%, losers = 11%). Findings suggest successful men’s and women’s teams adopt different tactical approaches to knockout competitions, this knowledge should be used as a basis for coaches to develop tactical approaches and training methods which are sex dependent

Cooperation between Referees and Authors Increases Peer Review Accuracy

Peer review is fundamentally a cooperative process between scientists in a community who agree to review each other's work in an unbiased fashion. Peer review is the foundation for decisions concerning publication in journals, awarding of grants, and academic promotion. Here we perform a laboratory study of open and closed peer review based on an online game. We show that when reviewer behavior was made public under open review, reviewers were rewarded for refereeing and formed significantly more cooperative interactions (13% increase in cooperation, P = 0.018). We also show that referees and authors who participated in cooperative interactions had an 11% higher reviewing accuracy rate (P = 0.016). Our results suggest that increasing cooperation in the peer review process can lead to a decreased risk of reviewing errors

The song of the dunes as a self-synchronized instrument

Since Marco Polo (1) it has been known that some sand dunes have the peculiar ability of emitting a loud sound with a well defined frequency, sometimes for several minutes. The origin of this sustained sound has remained mysterious, partly because of its rarity in nature (2). It has been recognized that the sound is not due to the air flow around the dunes but to the motion of an avalanche (3), and not to an acoustic excitation of the grains but to their relative motion (4-7). By comparing several singing dunes and two controlled experiments, one in the laboratory and one in the field, we here demonstrate that the frequency of the sound is the frequency of the relative motion of the sand grains. The sound is produced because some moving grains synchronize their motions. The existence of a velocity threshold in both experiments further shows that this synchronization comes from an acoustic resonance within the flowing layer: if the layer is large enough it creates a resonance cavity in which grains self-synchronize.Comment: minor changes, essentially more references

Supporting Treatment for Anti-Retroviral Therapy (START) together: protocol for a pilot, randomized, couple-based intervention to promote women's ART adherence and men's engagement in HIV care in KwaZulu-Natal, South Africa

Background: South Africa currently has the greatest number of people with HIV globally. The country has not yet met its 95-95-95 goals, with different gaps in the HIV care cascade for women and men. This paper reports on a protocol to pilot test a couple-based intervention designed to improve women's antiretroviral therapy (ART) adherence and men's engagement in care in heterosexual couples living in the Vulindlela area of KwaZulu-Natal, South Africa. Study goals are two-fold: (1) assess the acceptability, feasibility, and fidelity of the experimental intervention, START Together, and (2) collect efficacy data on START Together for women's ART adherence, men's engagement in HIV care, and the couple's relationship functioning. Methods: Women (N = 20) who were not engaged with ART adherence (defined via self-reported ART difficulties, record of missed clinic visits, or viral non-suppression) are the target patients; male partners are not required to know or disclose their HIV status to be part of the study. Couples are randomized 1:1 to the experimental treatment (START Together) or treatment as usual (referrals to the local clinic to support ART adherence or any other HIV-related care). START Together is a 5-session intervention based in cognitive-behavioral couple therapy, which is a skill-based intervention focusing on communication and problem-solving skills, and Life Steps, a problem-solving intervention identifying barriers and solutions to medication adherence. Couples are assessed at baseline, post-treatment (8 weeks post-randomization), and follow-up (12 weeks post-randomization). Conclusion: This study will provide preliminary implementation and efficacy data on whether this novel approach has potential to improve women and men's HIV and healthcare-related needs
