Postural evaluation in young skaters: effect of two proprioceptive training

The roller skating involves developing of motor and artistic skills from an early age. The aim was to evaluate the effects that an ocular a podalic proprioceptive training cause to postural control and stability in a sample of young skaters. A total of 25 skaters aged between 9 and 15 (12±2.14) divided into two groups: the eyes group (EG) aimed at exercising visual proprioception, the feet group (FG) aimed at exercising podalic proprioception. The participants were subject to through electronic stabilometry in static mode, open (OE) and closed (CE) eyes, in a time T0 (pre-training) and T1 (post-training), without and with skates. The results through the two paired t-test showed that both variables Wz (TotHz) to CE within the EG (p<.05) and Wx (TotHz) to CE within the FG (p<.05) were statistical significance. The unpaired t-test showed that the FG obtained a greater statistical significance than the EG for the VarVit and Wx (TotHz) variables in CE (p<.05) and Wz (TotHz) in both CE and OE (p<.05). The two-way ANOVA found statistical significance (p<.05) on the Wx (TotHz) variable in open/closed eyes of the FG (T0/T1). We concluded that in roller skating it could be useful to integrate athletic training with a visual proprioceptive training.

Business model configuration and dynamics for technology commercialization in mature markets.

Purpose The food industry is a well-established and complex industry. New entrants attempting to penetrate it via the commercialization of a new technological innovation could face high uncertainty and constraints. The capability to innovate through collaboration and to identify suitable strategies and innovative business models (BMs) can be particularly important for bringing a technological innovation to this market. However, although the potential for these capabilities has been advocated, we still lack a complete understanding of how new ventures could support the technology commercialization process via the development of BMs. The paper aims to discuss these issues. Design/methodology/approach To address this gap, this paper builds a conceptual framework that knits together the different bodies of extant literature (i.e. entrepreneurship, strategy and innovation) to analyze the BM innovation processes associated with the exploitation of emerging technologies; determines the suitability of the framework using data from the exploratory case study of IT IS 3D – a firm which has started to exploit 3D printing in the food industry; and improves the initial conceptual framework with the findings that emerged in the case study. Findings From this analysis it emerged that: companies could use more than one BM at a time; hence, BM innovation processes could co-exist and be run in parallel; the facing of high uncertainty might lead firms to choose a closed and/or a familiar BM, while explorative strategies could be pursued with open BMs; significant changes in strategies during the technology commercialization process are not necessarily reflected in a radical change in the BM; and firms could deliberately adopt interim strategies and BMs as means to identify the more suitable ones to reach the market. Originality/value This case study illustrates how firms could innovate the processes of their BM development to face the uncertainties linked with the entry into a mature and highly conservative industry (food)

Sterically Congested 2,6-Disubstituted Anilines from Direct C−N Bond Formation at an Iodine(III) Center

2,6-Disubstituted anilines are readily prepared from the direct reaction between amides and diaryliodonium salts. As demonstrated for 24 different examples, the reaction is of unusually broad scope with respect to the sterically congested arene and the nitrogen source, occurs without the requirement for any additional promoter, and proceeds through a direct reductive elimination at the iodine(III) center. The efficiency of the coupling procedure is further demonstrated within the short synthesis of a chemerin binding inhibitor

Length–weight relationships of bivalve species in Italian razor clam Ensis minor (Chenu, 1843) (Mollusca: Bivalvia) fishery

Length–weight relationships of bivalve species collected during razor clam (Ensis minor) surveys along Italian coastal waters (Northern Adriatic and Tyrrhenian Sea) in the 3-year period 2016–2018 are reported. A total of 13,588 individuals, belonging to 12 bivalve species and 20 populations between the Adriatic and Tyrrhenian Seas, were sampled for this study. Analyzing growth parameters for each population, we found 11 allometries and nine isometries. About half of the species investigated showed different growth characteristics between the two areas

Pots vs trammel nets: A catch comparison study in a Mediterranean small-scale fishery

Passive bottom-set nets are the most widely used fishing gears in Mediterranean small-scale fisheries (SSFs). Trammel nets, in particular, have key advantages such as their ease of use and handling and high capture efficiency for numerous commercial species. However, they entail high discard rates (5\u201344% of the total catch) connected to high mortality, thus exerting an adverse impact on benthic communities, besides catching individuals of commercial species under the minimum conservation reference size (MCRS) and specimens of protected species. Fish pots are seen as alternative and a more sustainable gear type that allow reducing discards in SSFs. In this study, a collapsible pot was tested at three coastal sites in the north-western Adriatic Sea (GFCM GSA 17) to compare its catch efficiency with that of the local traditional trammel nets. Data analysis demonstrated a similar catch efficiency for the commercial species, both among sites and as a whole. Moreover, the trammel net caught a larger amount of discards, both in terms of species number and of CPUEW. The catch comparison study involved the two most abundant landed species, common cuttlefish Sepia officinalis and annular sea bream Diplodus annularis. The pots were more effective for S. officinalis, whereas the trammel net was more effective for the shorter length classes for D. annularis, which were mostly under the MCRS (12 cm). The innovative pots could provide a valuable alternative to the trammel nets traditionally used in the Adriatic Sea, at least in certain areas and periods. Their main advantages include that they do not require a different rigging and they can be used without bait, while their foldable design allows large numbers to be easily loaded on board SSF vessels. The results of this pilot study indicate that pots can achieve the objectives of reducing discards and bycatch in SSFs without penalizing the catch of commercial species

Complementary Spiritist Therapy: Systematic Review of Scientific Evidence

Spiritism is the third most common religion in Brazil, and its therapies have been used by millions worldwide. These therapies are based on therapeutic resources including prayer, laying on of hands, fluidotherapy (magnetized water), charity/volunteering, spirit education/moral values, and disobsession (spirit release therapy). This paper presents a systematic review of the current literature on the relationship among health outcomes and 6 predictors: prayer, laying on of hands, magnetized/fluidic water, charity/volunteering, spirit education (virtuous life and positive affect), and spirit release therapy. All articles were analyzed according to inclusion/exclusion criteria, Newcastle-Ottawa and Jadad score. At present, there is moderate to strong evidence that volunteering and positive affect are linked to better health outcomes. Furthermore, laying on of hands, virtuous life, and praying for oneself also seem to be associated to positive findings. Nevertheless, there is a lack of studies on magnetized water and spirit release therapy. In summary, science is indirectly demonstrating that some of these therapies can be associated to better health outcomes and that other therapies have been overlooked or poorly investigated. Further studies in this field could contribute to the disciplines of Complementary and Alternative Medicine by investigating the relationship between body, mind, and soul/spirit

Grandi e piccole imprese nel Centro-Nord e nel Mezzogiorno: un modello empirico dell&#8217;impatto occupazionale nel lungo periodo

Questo lavoro presenta una verifica dell'ipotesi formulata in Florio (1991, 1996) secondo cui le relazioni fra grandi e piccole imprese sono la risultante di due forze opposte. Da un lato le grandi imprese possono agire come propulsori di sviluppo locale secondo modelli di propagazione ben studiati dal punto di vista teorico ed empirico. D'altro canto le stesse grandi imprese, soprattutto in settori e contesti ambientali deboli, possono avere effetti di spiazzamento dell'offerta locale in particolare attraverso il reclutamento come dipendenti di potenziali piccoli imprenditori. Quale delle due forze prevalga non pu\uf2 essere detto in generale, ma va esaminato in diversi periodi, settori, contesti regionali. Il tema ha particolare rilevanza nel caso italiano sotto il profilo delle politiche pubbliche, in particolare del ruolo che le politiche di sviluppo regionale e per l'occupazione dovrebbero assegnare alle grandi imprese, anche in considerazione dei processi di ristrutturazione che le coinvolgono (Giunta, 1997). Fra queste politiche in Italia, ad esempio, vi sono i contratti di programma con i quali lo Stato sussidia grandi progetti industriali in aree depresse (Florio, Giunta, 1998). Il presente testo non intende rispondere in modo definitivo alla questione proposta, ma suggerisce una metodologia che potr\ue0 essere ulteriormente sviluppata. Per lo svolgimento dell'analisi \ue8 stata costruita una base-dati che comprende dati censuari e dati Inps a base provinciale. In particolare i dati dei censimenti sono stati raccolti dal 1951 al 1991, con una copertura quindi pari a mezzo secolo di storia economica nazionale, aggiornando e migliorando un analogo esercizio presentato in Florio (1991). Il lavoro \ue8 strutturato come segue: a) una prima sezione presenta alcune considerazioni suggerite dall'esame dei dati; b) la seconda sezione presenta un modello empirico; c) nella terza sezione sono esposti i risultati. In appendice, sono riportati per esteso i dati provinciali utilizzati. Gli autori saranno lieti di fornire tale base-dati su dischetto ad altri ricercatori che desiderino verificare o estendere l'analisi
