Mathematics Anxiety and Its Development in the Course of Formal Schooling—A Review  [PDF]
Chiara Eden, Angela Heine, Arthur M. Jacobs
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.46A2005

The purpose of the this article is to provide an overview of the current state of research concerning the development, determining factors and effects of mathematics anxiety, particularly with regard to young elementary school age level populations. Assessment instruments, potential risk-factors, consequences of mathematics anxiety, as well as approaches to intervention are summarized. Owing to the small number of studies focusing on mathematics anxiety in young children, findings from adult studies are briefly recapitulated. The available data emphasizes the need for systematic research that focuses on the one hand on the onset of mathematics anxiety at a young age, and on the other follows the development of longer periods of time. Furthermore, multi-method research designs may be the means to gain deeper insight into the dynamics of causes and effects when the interaction of mathematics anxiety and mathematical abilities are under scrutiny. Only by implementing longitudinal studies that involve different types of data and the formulation of complex models of the dynamics of mathematics anxiety over time, can its determining factors and its effects be generated.

Suggestions on Writing for Publication in Language Learning Journals
George M. Jacobs
TEFLIN Journal , 1999,
Abstract: This article provides suggestions on writing for journals in the field of language learning. These suggestions are presented in three sections. The first section discusses how to begin. Suggestions in this section are that we appreciate the benefits of writing for publication, develop good ideas, work efficiently, ponder options as to what type of writing to do, choose a good topic, consider replication of other's research, and cooperate with others. The second section presents suggestions on doing the actual writing. Here, it is suggested that we connect ideas, delve deeply into the ideas we present, strive to write the reader friendly manner, use visuals, and improve our writing by noticing how other journal authors write. The third section concerns relations with editors. The advice given is that we choose carefully the journal to which we submit our work, follow that journal's directions to contributors, include a cover letter, be prepared to wait patiently, welcome critical feedback from editors and reviewers, and view editors as colleagues.
The work of Daphne Hampson: The God talk of one feminist theologian
Maretha M. Jacobs
HTS Theological Studies/Teologiese Studies , 2009, DOI: 10.4102/hts.v63i1.198
Abstract: For almost all of human history both in ancient times and in modern contexts, talk about God has been mainly a male preserve. So closely has male God talk been associated by many with God’s own voice, that it is still not commonly realized and acknowledged. With the rise of feminism, especially during recent decades, it has changed. In this article the work of Daphne Hampson, a British feminist theologian, is considered: Her definition and critique of Christianity, her view of the relation between the present and our Christian past, specifically with regard to God talk, her dealing with prominent aspects of the Christian belief system and her emphasis on taking seriously all available knowledge and our contemporary context in doing theology. In line with some current trends in God talk, such as a movement away from anthropomorphism, and in dialogue with Friedrich Schleiermacher, she formulates what she calls a “future theism”.

Effective approach to non-relativistic quantum mechanics
David M. Jacobs
Physics , 2015,
Abstract: Non-trivial self-adjoint extensions in quantum mechanics have been used in the past to model contact interactions when those interactions are expected a priori. However, real physical systems can only ever be understood to a finite resolution, so there exists a generic ignorance of possible short-range interactions. To address this issue, a real-space approach is described here wherein an artificial boundary is inserted at an intermediate scale to explicitly hide possible short-distance effects. Boundary conditions may then encode physical effects that are hidden behind the boundary, thereby effectively capturing the set of possible UV completions. Using this approach, a non-relativistic analysis is performed of the free particle, harmonic oscillator, and Coulomb potential in three dimensions. Requiring measurable quantities, such as spectra and cross sections, to be independent of the position of the boundary, renormalization group-type equations are derived that determine how the boundary conditions run. Generically, observables differ from their canonical values and symmetries are anomalously broken. Connections are made to well-studied physical systems, such as the deuteron and condensed matter systems that employ Feshbach resonances.
Approach the Good, Withdraw from the Bad—A Review on Frontal Alpha Asymmetry Measures in Applied Psychological Research  [PDF]
Benny B. Briesemeister, Sascha Tamm, Angela Heine, Arthur M. Jacobs
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.43A039

Basic research has established a strong relationship between stimulus induced human motivation for approach-related behavior and left-frontal electrophysiological activity in the alpha band, i.e. frontal alpha asymmetry (FAA). Since approach motivation is also of interest for various fields of applied research, several recent studies investigated the usefulness of FAA as a diagnostic tool of stimulus induced motivational changes. The present review introduces the theory and the methods commonly used in approach/ withdrawal motivation research, and summarizes work on applied FAA with a focus on product design, marketing, brain-computer communication and mental health studies, where approach motivation is of interest. Studies investigating and developing the application of FAA training in the treatment of affective disorders such as major depressive disorder and anxiety disorder are also introduced, highlighting some of the future possibilities.

Relation between mean arterial pressure and renal function in the early phase of shock: a prospective, explorative cohort study
Frédéric M Jacobs
Critical Care , 2011, DOI: 10.1186/cc10417
Abstract: In this study, a difference exists between patients with AKI and those without AKI. Patients with AKI at 6 hours have a significantly higher volume expansion in the last 6 hours before inclusion. Volume expansion (a cornerstone of sepsis treatment) can lead to an increase in abdominal pressure [2]. This condition is not infrequent, even among medical patients [3], particularly during early septic shock [4].Thus, the beneficial effect on renal function of a higher MAP may be linked to the preservation of abdominal perfusion pressure and filtration gradient (FG) rather than to the impairment of renal autoregulation. We have shown (though only with preliminary results) that even a very moderate elevation of intra-abdominal pressure (IAP) can lead to a significant decrease of FG when the systemic hemodynamic is profoundly altered [5].Thus, it cannot be excluded that the higher MAP threshold in the septic group is linked to a higher IAP value. The relevant goal may be not to aim for a minimal MAP of more than 65 mm Hg to prevent AKI at the early phase of septic shock but to target a sufficient MAP value to preserve abdominal perfusion pressure and FG by monitoring IAP.Julie Badin and Thierry BoulainWe thank Dr. Jacobs for his relevant remarks concerning our work [1]. Although we did not measure IAP, we examined the influence of the amount of fluid administered on AKI: the amount of fluid, administered either before or during the first 72 hours and examined by quartiles, was not linked to the proportion of AKI at 72 hours in the whole population or in patients with sepsis or AKI at 6 hours (P >0.1 in all cases by chi-square test). Furthermore, in the population that Dr. Jacobs refers to (septic shock and initial AKI), the areas under the receiver operating characteristic curve of time-averaged MAP to predict AKI at 72 hours were very similar in patients who received less than 2,000 mL (the median amount of fluid received) before inclusion and those who received 2,000 mL o
Temporal Variability Corrections for Advanced Microwave Scanning Radiometer E (AMSR-E) Surface Soil Moisture: Case Study in Little River Region, Georgia, U.S.
Minha Choi,Jennifer M. Jacobs
Sensors , 2008, DOI: 10.3390/s8042617
Abstract: Statistical correction methods, the Cumulative Distribution Function (CDF) matching technique and Regional Statistics Method (RSM) are applied to adjust the limited temporal variability of Advanced Microwave Scanning Radiometer E (AMSR-E) data using the Common Land Model (CLM). The temporal variability adjustment between CLM and AMSR-E data was conducted for annual and seasonal periods for 2003 in the Little River region, GA. The results showed that the statistical correction techniques improved AMSR-E’s limited temporal variability as compared to ground-based measurements. The regression slope and intercept improved from 0.210 and 0.112 up to 0.971 and -0.005 for the non-growing season. The R2 values also modestly improved. The Moderate Resolution Imaging Spectroradiometer (MODIS) Leaf Area Index (LAI) products were able to identify periods having an attenuated microwave brightness signal that are not likely to benefit from these statistical correction techniques.
Die invloed van reuke op die werksatmosfeer van saalpersoneel binne 'n gespesialiseerde verpleegopset
M. Jacobs,A. L. Barnard
South African Journal of Industrial Psychology , 1996, DOI: 10.4102/sajip.v22i3.612
Abstract: The influence of odours on the work atmosphere of ward personnel within a specialised healthcare setting. The purpose of the investigation was to determine whether pleasant odours could make a positive contribution to the disposition of ward staff and their experience of the work ambience. A random test method was used to select two samples from a possible four wards. The sixteen men and women were allocated to experimental and control groups at random. The results indicate that odours could make a positive difference to the disposition of workers. No such positive influence was, however, observed with regard to the work ambience. Opsomming Die doel van die ondersoek was om vas te stel of aangename reuke die gemoedstoestand en belewenis van die werksatmosfeer van saalpersoneel positief kan beinvloed. Die lotingsmetode is gebruik om uit vier sale, twee ewekansige groepe te selekteer. Die sestien mans en vroue is ewekansig toegedeel aan 'n eksperimentele en kontrolegroep. Die resultate wys dat reuke wel 'n positiewe verskil aan die gemoedstoestand van 'n werker kan maak. Geen sodanige positiewe invloed is egter ten opsigte van werksatmosfeer waargeneem nie.
