Snub Publishing: Evidence from the Anthurium Literature

Snub publishing is a new term that was coined in 2013 to describe a range of publishing cases in which the failure of quality control manifested itself through references in such a way that it would cause unintended damage to snubbed scientists whose names or identity were incorrectly represented in the literature. In this paper, real case studies are presented, mostly related to the author as a “victim” of incompetent editorial oversight, inexperienced or biased authors, or as a “victim” of direct professional conflicts of interest. In essence, this paper serves as a prototype showing in concrete terms how a scientist can or may be professionally snubbed (intentionally or unintentionally). Using the Anthurium literature, this paper aims to raise awareness about snub publishing and seeks to encourage other scientists to also quantify how they too may have been professionally snubbed in the literature.     

Waiting for the Tide to Change? Strategies for Survival of Portuguese Private HEIs

The topic of declining private higher education (PHE) has become a timely one, especially for many countries that had previously experienced a rapid and massive expansion of their systems of higher education, and of PHE in particular. In the case of Portugal this was very likely due to the stabilisation and then the slight decline in the number of applicants and the steady expansion of the public system Thus, the Portuguese system has become an interesting case study of the several types of strategies that may be adopted by PHE institutions when facing a declining student demand.     

High-volume resistance training reduces postprandial lipaemia in postmenopausal women

The aim of this study was to compare the effects of 11 weeks of low-volume resistance training (LVRT) and high-volume resistance training (HVRT) on muscle strength, muscle thickness (MT), and postprandial lipaemia (PPL) in postmenopausal women. Thirty-six healthy and untrained postmenopausal women (age, 58.9 ± 5.8 years; 68.6 ± 10.3 kg; and BMI, 26.9 ± 4.8 kg · m^?2) participated in resistance training 3× per week for 11 weeks (HVRT = 12; LVRT = 13; and control group = 11). Biochemical variables, both pretraining and post-training, were evaluated 16 h after the administration of an oral fat tolerance test (OFTT) and metabolic variable during [energy expenditure (EE)] and after training session [excess postexercise oxygen consumption (EPOC)]. Muscle strength (1 RM) and MT were also calculated, and no significant differences were observed between the groups for PPL (mmol · L^?1 per 5 h) as measured by glucose, high-density lipoprotein, low-density lipoprotein, and total cholesterol. EE total (EE + EPOC; 6.12 ± 1.21 MJ vs. 2.26 ± 0.85 MJ), resting fat oxidation (5.52 ± 1.69 g · h^?1 vs. 4.11 ± 1.12 g · h^?1); MT (vastus medialis, 21.4 ± 1.8 mm vs. 18.4 ± 1.2 mm and vastus lateralis 22.3 ± 1.2 mm vs. 20.8 ± 1.3 mm); triacylglycerol (TAG) 0, 1, 2, 4; and 5 h after OFTT, TAG area under the curve (AUC) (5.79 ± 0.42 vs. 7.78 ± 0.68), and incremental AUC (?46.21 ± 14.42% vs. 7.78 ± 4.68%) were all significantly different post-training for HVRT versus LVRT, respectively (P < 0.05). The results of this investigation suggest that HVRT reduces PPL in postmenopausal women.     

Developmental changes in the comparison of decimal fractions

Learning about decimal fractions is difficult because it requires an extension of the number concept built on natural numbers. The aim of the present study was to investigate developmental changes in children's misconceptions in decimal fraction processing. A large sample of children from Grades 3 to 6 performed a numerical comparison task on different categories of pairs of decimal fractions. The success rate and the type of error they made varied with age and categories. We distinguished the impact of the value of the digits from the impact of the length of the fractional part on children's pattern of responses. Although both kinds of impact affected the success rate, the digit values had a stronger impact and were mastered later than the length. Our results also showed that a zero just after the decimal point was understood better and earlier than a zero at the end of the fractional part of a number. Cluster analysis was conducted to determine groups of children who answered similarly regarding the response type across the various categories of decimal fractions. To interpret the data the conceptual change framework was used.     

Nutritional intake of elite football referees

Abstract

There is a paucity of dietary data in football referees. In this study, 23 elite main and assistant referees (34.4 ± 5.6 years) completed a 7-day dietary record during the competitive season. No nutritional intake differences were observed between main and assistant referees. Referees’ mean daily energy intake (DEI) was 2819 ± 279 kcal. The intake of proteins (1.7 ± 0.2 g · kg^?1), carbohydrates (4.1 ± 0.8 g · kg^?1) and fats (1.4 ± 0.2 g · kg^?1) represented, respectively, 18.4 ± 1.5%, 44.4 ± 4.4% and 34.6 ± 4.1% of the DEI. Carbohydrate intakes before, during and after exercise were 66 ± 42, 7 ± 15 and 120 ± 62 g. Daily carbohydrate, fibre, polyunsaturated fat and water intakes were below recommendations, while fat, saturated fat, cholesterol and sodium intakes were above recommended values. The prevalence of inadequate intake was high for vitamin E (96%), folate (74%), vitamin A (61%), vitamin C (39%), magnesium (26%) and calcium (22%). Carbohydrate intake before, during and after exercise were far from achieving the minimum recommended values. Most referees demonstrated a negligent behaviour of hydration during exercise. Referees would benefit from dietary education in order to optimise performance and health.     

Hong Kong secondary school students’ attitudes towards science: a study of structural models and gender differences

This paper is concerned with children's conceptions of the structure and function of the human digestive system. It is based on data from an investigation carried out with 45 children between the ages of four and ten. The results indicated that (1) children possess biological knowledge as an independent knowledge domain from the age of 4; (2) the acquisition of the concept of digestion leads to a conceptual revision and enrichment; (3) the concept of transformation can constitute an obstacle to comprehension of the scientific model of the functions of the digestive system.     

Formative assessment in primary science

This action learning study in a year three classroom explored the implementation of five formative assessment principles to assist students' understandings of the scientific topic of liquids and solids. These principles were employed to give students a greater opportunity to express their understanding of the concepts. The study found that the principles of formal assessment worked well in concert with the pedagogical framework of the interactive teaching model.     

Development and evaluation of a Portuguese early literacy programme / Desarrollo y evaluación de un programa portugués de alfabetización temprana

Abstract

Over the last three decades, research in this field has addressed different early literacy skills and studied the pedagogical practices that promote the initial learning of reading and writing skills. This study develops a programme that promotes early literacy skills, called Ouvir as Letras (Listen to the Letters). The efficacy of the programme was evaluated in comparison with two implementations of the Portuguese preschool education curriculum: one structured and the other semi-structured, in a quasi-experimental design with a pre-test, post-test and follow-up. The study was carried out with the participation of 124 five- and six-year-old children who attended preschool in four schools in the north of Portugal. The results suggest that the Ouvir as Letras programme was more effective in facilitating the acquisition of basic skills to initiate children in the learning of written language.     

The Macro and Micro Scale of Open Access Predation

Having found a business opportunity in exploiting the open access publishing model, predatory journals and publishers have been spamming authors with emails, inviting them to submit articles for publication. Authors may be misled by the names of prestigious authors and editors that predatory journals and publishers use to advertise their publishing services, either by claims that those scientists serve on the editorial boards or by sending invitations in their names. Given the fact that detailed knowledge of a journal is required to make an informed decision of whether the inviting journal is predatory or not, junior scientists are not likely to possess the knowledge or skill to make such decisions. In addition, analysis of the details of new suspicious journals and publishers can be a lengthy process or even a waste of time. Therefore, in this paper, we provide an analysis of a likely scenario that many authors are facing nowadays when they take on the difficult task of studying the details of suspicious journals as possible venues for the publication of their research findings. The analysis takes the form of an analysis of the Kenkyu Publishing Group, which is listed on Jeffrey Beall’s list of “predatory” open access publishers.
