Integrated Reporting and the Directions of Its Development
Authors: Krasodomska Joanna
Published: July 2019

The aim of the paper is to present the concept of integrated reporting. Its aim is to explain to the stakeholders how value is created by a company with the use of its resources and relations as well as interactions with the external environment. The integrated reporting framework has been developed by the International Integrated Reporting Council, and the reason for this was the economic crisis. It seems that in view of the limitations of traditional financial accounting, it is advisable for companies to start practicing integrated reporting. This issue is also worth addressing within contemporary accounting research.
Controlling as an Information Source in Risk Management Process
Authors: Dynowska Joanna , Bartoszewicz Anna
Published: July 2019

An increasingly visible tool in identifying risk is controlling. Its tasks include collecting, processing, and analyzing information. Thus, in the stage of identifying the risk management process, controlling should supply management with information regarding the impacts of risks on particular departments of the company. The purpose of this article was to emphasize the role of controlling in the risk management process within an organization. This objective was achieved through a study of literature from research conducted in the field. Over the course of this study, the value of controlling and its role in the risk management process were revealed. Also, the role of budgeting was shown to be a key tool of controlling in the process of risk management. The implementation of controlling in a company permits full use of information and enables the use of modern management techniques, thereby facilitating making good decisions to rectify or mitigate risk for a specific organization or unit.
Image Building Strategy on the Example of Selected Polish Regions
Authors: Stanowicka Agnieszka
Published: July 2019

The objective of this study was to identify and evaluate image building strategies in selected Polish regions. A mail questionnaire survey was carried out in 2013 in the regions of Pomorze (Pomerania), Pomorze Zachodnie (West Pomerania), Małopolska (Lesser Poland), Podkarpacie (Subcarpathia), Warmia and Mazury (Warmia and Masuria), and Podlasie. The importance of image building strategies is widely recognized by the local authorities, but most strategies are implemented on a short-term or medium-term basis. Image building strategies are often regarded as auxiliary measures that contribute to the achievement of strategic development goals. In the analyzed regions, image building is often reduced to strictly promotional measures. The relevant strategies focus on too many landmarks of regional identity, which detracts from their effectiveness. An absence of regular market surveys and evaluations also contributes to the weakness of regional image building strategies.
European Pork Chains : the Role of Stakeholders in Diversification of Quality Management Systems
Authors: Szymanowski Wacław
Published: July 2019

The paper presents the results of the diagnose concerning the characteristics of pork chains in 6 European Union countries: France, Greece, Spain, The Netherlands, Germany and Hungary. The aim of the paper is to present the differences and fragmentary character of the chains in the pork sector in Europe and diversification of demand for pork products in rapidly developing European markets. Determination of presence of differences in the quality management systems in 6 chosen European countries, i.e. France, Greece, Spain, The Netherlands, Germany and Hungary is the main hypothesis of the paper. Three of those differences apply to specialised pork chains (Spain, The Netherlands and Hungary) while the other three the regional pork chains (France, Greece and Germany). The nature of those chains results from the differences in utilisation of public and private quality management systems and the differences between inter-organisational quality management systems within the chains of supplies strengthening quality cohesion and safety between the links of the chain. The comparison of them allows formulating conclusions for reconstruction of the pork chains in Poland.

Published: July 2019

The example presented in the paper explains operation of the phenomenon known in the literature as the "taxation paradox" that means that the net present value of the investment after considering taxation is higher than the net present value after taxation or the other way round. The aim is to present that dismissing the taxation aspects in the decision taking processes may result in inappropriate choices or lead to resignation from a profitable investment project by investors.
Quality of Location in Regions and Economic Efficiency of Private Companies in Poland
Authors: Wierzbicka Wioletta
Published: July 2019

Evaluation of the correlation between the economic efficiency level of private companies in Poland and the quality of location in the regions was the aim of the study. Based on the conducted analyses it was established that the level of sales markets absorptiveness shows the strongest correlation with the level of economic efficiency of the companies surveyed. The majority of regions characterised by absorptive sales markets also recorded good results in economic efficiency of companies located there while voivodships with low internal demand were characterised by definitely lower efficiency. Increasingly strong correlation was also recorded between the economic efficiency level of the companies surveyed and the level of knowledge in the regions. This may be the signal that currently the location factors of "soft" nature present increasing influence on the efficiency of companies and it is not impossible that their importance will continue increasing.

Authors: Bilchak Vasiliy , Duplenko Natalia
Published: July 2019

The aim of the conducted study was to identify the regularities of the regional asymmetry of development of small and medium enterprise. The subject of the study is the influence of the area factors on the activities of small and medium-sized businesses. The authors are proposing their own original method of assessment of the regional asymmetry of small and medium enterprise development. The study enabled the authors to identify the following regularities. Firstly, the level of the regional asymmetry of small and medium enterprise development does not depend on the size of the area occupied by the region. Secondly, the level of the asymmetry is inversely proportional to the level of the economic development of the region. Besides that, the case study ofthe North-West federal district ofthe Russian Federation revealed a number of features of the regional asymmetry of small and medium enterprise development in the countries having significant territorial expanse.

Matching NBP interest rates to different versions of the Taylor rule
Authors: Grabia Tomasz
Published: July 2019

The interest rate is the basic instrument of monetary policy, directly or indirectly affecting basic macroeconomic variables, such as inflation, unemployment and economic growth. The aim of the article is to compare the NBP reference rate with hypothetical rates calculated on the basis of different variants of the Taylor rule and to indicate which of those variants is best suited to the situation in Poland. The study period of 2000-2017 was adopted for the analysis. On its basis, it was found that in most cases the real interest rate of the central bank in Poland strongly coincided with rates that would have been set if one of the varieties of the Taylor rule had been in force. The best match coincided with the modified version of this rule, which was created after the economic crisis. That means that the NBP took into account both the deviations of inflation from the target and the GDP gap when making decisions regarding interest rates.

Effect of segmental lordosis on the clinical outcomes of 2-level posterior lumbar interbody fusion for 2-level degenerative lumbar spondylolisthesis
Authors: Takahashi Yoshifumi , Okuda Shinya , Nagamoto Yukitaka , Matsumoto Tomiya , Sugiura Tsuyoshi , Iwasaki Motoki
Published: July 2019

OBJECTIVE

Although the importance of spinopelvic sagittal balance and its implications for clinical outcomes of spinal fusion surgery have been described, to the authors’ knowledge there have been no reports of the relationship between spinopelvic alignment and clinical outcomes for 2-level posterior lumbar interbody fusion (PLIF). The purpose of this study was to elucidate the relationship between clinical outcomes and spinopelvic sagittal parameters after 2-level PLIF for 2-level degenerative spondylolisthesis (DS).

METHODS

This study was limited to patients who were treated with 2-level PLIF for 2-level DS at L3–4-5. Between 2005 and 2014, 33 patients who could be followed up for at least 2 years were included in this study. The average age at the time of surgery was 72 years, and the average follow-up period was 5.6 years. Based on clinical assessments, the Japanese Orthopaedic Association (JOA) score and recovery rate were evaluated. The patients were divided into 2 groups based on the recovery rate: the good outcome group (G group; n = 19), with recovery rate ≥ 50%, and the poor outcome group (P group; n = 14) with recovery rate < 50%. Spinopelvic parameters were measured using lateral standing radiographs of the whole spine as follows: sagittal vertical axis (SVA), thoracic kyphosis (TK), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), lumbar lordosis (LL), and segmental lordosis (SL) at L3–4-5. The clinical outcomes and radiological parameters were assessed preoperatively and at the final follow-up. Radiological parameters were compared between the 2 groups.

RESULTS

The mean JOA score improved significantly in all patients from 10.8 points before surgery to 19.6 points at the latest follow-up (mean recovery rate 47.7%). For radiological outcomes, no difference was observed from preoperative assessment to final follow-up in any of the spinopelvic parameters except SVA. Although no significant difference between the 2 groups was detected in any of the spinopelvic parameters, there were significant differences in the change in SL and LL (ΔSL 3.7° vs −2.1° and ΔLL 1.2° vs −5.6° for the G and P groups, respectively). In addition, the number of patients in the G group was significantly larger for the patients with ΔSL-plus than those with ΔSL-minus (p = 0.008).

CONCLUSIONS

The clinical outcomes of 2-level PLIF for 2-level DS limited at L3–4-5 appeared to be satisfactory. The results indicate that acquisition of increased SL in surgery might lead to better clinical outcomes.
PROMIS correlation with NDI and VAS measurements of physical function and pain in surgical patients with cervical disc herniations and radiculopathy
Authors: Owen Robert J. , Khan Adam Z. , McAnany Steven J. , Peters Colleen , Zebala Lukas P.
Published: July 2019

OBJECTIVE

The aim of this study was to compare the patient-reported outcome measures Neck Disability Index (NDI) and visual analog scale (VAS) with the Patient Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference (PI) measures, respectively, and to determine their correlations in a surgical population longitudinally.

Legacy outcome measures such as NDI and VAS are essential for analyzing treatments in spine surgery for cervical disc herniations with radiculopathy. Despite their usefulness, administrative burdens impose limits on completion of these measures. PROMIS was developed as a patient outcome measure in order to improve reporting of patient symptoms and function and to reduce administrative burden. Despite early positive results of PROMIS in orthopedics, NDI and VAS scores have not been compared with PROMIS scores in patients with cervical disc herniations with radiculopathy.

METHODS

Eighty patients undergoing surgery for cervical disc herniations with radiculopathy were included. All patients were treated at the same tertiary spine center. Patients were seen and PROMIS PF and PI, NDI, and VAS arm and neck pain scores were collected preoperatively and at 1 year postoperatively. Correlations between NDI, VAS, and PROMIS PF and PI were quantified using Pearson correlation coefficients. Two-tailed Student t-tests were used to demonstrate correlation significance, with alpha = 0.05.

RESULTS

All 80 (100%) patients completed all preoperative questionnaires. Fifty-seven (72%) and 75 (94%) patients completed all questionnaires at baseline and at the 6-month and 1-year follow-ups, respectively. PROMIS PF and NDI scores demonstrated a strong negative correlation, with Pearson r values of −0.81, −0.77, and −0.75 at baseline, 6 months, and 1 year. PROMIS PI and VAS neck pain scores demonstrated a moderately positive correlation, with Pearson r values of 0.51, 0.61, and 0.6. PROMIS PI and VAS arm pain scores demonstrated a moderately positive correlation, with Pearson r values of 0.46, 0.47, and 0.45.

CONCLUSIONS

PROMIS PF scores have a strong negative correlation with NDI scores at baseline and in the postoperative course in patients undergoing surgery for cervical disc herniations with radiculopathy. PROMIS PI scores have a moderately positive correlation with VAS neck and arm pain scores at baseline and in the postoperative course. Surgeons may factor these correlation results into the interpretation of patient-reported outcome measures in patients with cervical radiculopathy. Use of PROMIS PF and PI for this patient population may reduce administrative burden while providing reliable outcomes data.

OBJECTIVE

Patients with cervical spinal cord injury (SCI)/tetraplegia consistently rank restoring arm and hand function as their top functional priority to improve quality of life. Motor nerve transfers traditionally used to treat peripheral nerve injuries are increasingly used to treat patients with cervical SCIs. In this article, the authors present early results of a prospective clinical trial using nerve transfers to restore upper-extremity function in tetraplegia.

METHODS

Participants with American Spinal Injury Association (ASIA) grade A–C cervical SCI/tetraplegia were prospectively enrolled at a single institution, and nerve transfer(s) was performed to improve upper-extremity function. Functional recovery and strength outcomes were independently assessed and prospectively tracked.

RESULTS

Seventeen participants (94.1% males) with a median age of 28.4 years (range 18.2–76.3 years) who underwent nerve transfers at a median of 18.2 months (range 5.2–130.8 months) after injury were included in the analysis. Preoperative SCI levels ranged from C2 to C7, most commonly at C4 (35.3%). The median postoperative follow-up duration was 24.9 months (range 12.0–29.1 months). Patients who underwent transfers to median nerve motor branches and completed 18- and 24-month follow-ups achieved finger flexion strength Medical Research Council (MRC) grade ≥ 3/5 in 4 of 15 (26.7%) and 3 of 12 (25.0%) treated upper limbs, respectively. Similarly, patients achieved MRC grade ≥ 3/5 wrist flexion strength in 5 of 15 (33.3%) and 3 of 12 (25.0%) upper limbs. Among patients who underwent transfers to the posterior interosseous nerve (PIN) for wrist/finger extension, MRC grade ≥ 3/5 strength was demonstrated in 5 of 9 (55.6%) and 4 of 7 (57.1%) upper limbs 18 and 24 months postoperatively, respectively. Similarly, grade ≥ 3/5 strength was demonstrated in 5 of 9 (55.6%) and 4 of 7 (57.1%) cases for thumb extension. No meaningful donor site deficits were observed. Patients reported significant postoperative improvements from baseline on upper-extremity–specific self-reported outcome measures.

CONCLUSIONS

Motor nerve transfers are a promising treatment option to restore upper-extremity function after SCI. In the authors’ experience, nerve transfers for the reinnervation of hand and finger flexors showed variable functional recovery; however, transfers for the reinnervation of arm, hand, and finger extensors showed a more consistent and meaningful return of strength and function.

Authors: Goel Atul , Prasad Apurva , Shah Abhidha , Rai Survendra , Patil Abhinandan , Vutha Ravikiran
Published: July 2019

This is a report of 3 relatively rare clinical cases in which the absence of posterior elements of the axis was associated with basilar invagination and multiple other craniovertebral junction musculoskeletal and neural abnormalities. Atlantoaxial fixation resulted in remarkable clinical recovery in all 3 cases. C2–3 fixation was not done, and bone decompression was not done. On the basis of their experience, the authors conclude that atlantoaxial fixation is a satisfactory form of surgical treatment in patients having an association of basilar invagination with absent posterior elements of axis.
A (IN) VIABILIDADE DA UTILIZAÇÃO DO TERMO DE AJUSTAMENTO DE CONDUTA PARA DIRIMIR CONFLITOS AMBIENTAIS
Authors: Barbosa Dyego Porto , Carvalho Vâina Ágda Oliveira
Published: July 2019

Tendo em vista a insuficiência processual do Código de Processo Civil de 1973 para o processo coletivo, que se aplica ao bem ambiental, fez-se necessária a utilização de um microssistema, comtemplado, aqui com destaque, pela Lei 7.347/85 (Lei da Ação Civil Pública) que traz, em seu bojo, a possibilidade de um Termo de Ajustamento de Conduta como instrumento processual de solução alternativa de conflitos. Ressalta-se, entretanto, que este instrumento também é utilizado em sede extrajudicial. Contudo, diante as características peculiares do bem ambiental, pondera-se acerca de sua utilização, posto parâmetros dicotômicos entre o direito material e o processual. Assim, tem-se, como objetivo geral, a análise da compatibilidade entre a natureza jurídica do TAC e a natureza jurídica do bem ambiental. Para tanto, o método de pesquisa foi o teórico-jurídico com raciocínio dedutivo e técnica de pesquisa bibliográfica e documental, que permitiu concluir pela viabilidade do TAC para dirimir conflitos ambientais.

O estudo objetivou identificar se microempresas do setor de vestuário utilizam o processo de planejamento estratégico e se este é um fator determinante para seu crescimento e permanência no mercado. Para sua formatação, participaram da investigação um grupo de microempresas do setor de vestuário, localizados no município mineiro de Juiz de Fora. Trabalhou-se com uma pesquisa bibliográfica seguida de uma pesquisa de campo, onde foi possível realizar as conclusões. Os dados foram coletados por meio de questionários aplicados presencialmente a 14 microempreendedores, nos meses de setembro e outubro do ano de 2018. Os resultados demonstraram que algumas empresas não adotam o processo de planejamento estratégico, mesmo que, informalmente e outras somente algumas partes desse processo. Apesar de não fazerem uso dessa prática, a maioria dessas empresas está no mercado a mais de dez anos, o que deixa claro que este não é um fator preponderante para a sobrevivência das mesmas.
A TERCEIRIZAÇÃO COMO INSTRUMENTO DE PRECARIZAÇÃO DOS DIREITOS TRABALHISTAS
Authors: Dos Reis Fernanda Maria
Published: July 2019

O presente trabalho tem por escopo analisar a terceirização sob a perspectiva da precarização do trabalho. Sabe-se que essa relação triangular de trabalho, objetiva a redução dos custos e o aumento dos lucros, o que se dá, via redução do padrão dos direitos concedidos aos trabalhadores. Tal circunstância, faz da terceirização um dos temas mais instigantes e discutidos na esfera trabalhista, tendo referida discussão ganhado fôlego ao longo dos dois últimos anos com a leis 13.429/2017, 13.467/2017 (a reforma trabalhista) e, ainda, com as recentes decisões proferidas pelo Supremo Tribunal Federal quando do julgamento da ADF 324 e do RE 958252, ambos no ano de 2018. O presente estudo, foi realizado através de pesquisa bibliográfica, em doutrina, legislação, jurisprudência e artigos científicos publicados em periódicos online e também impressos. Ao final conclui-se que, diante da autorização pela legislação ordinária e pela jurisprudência, a terceirização é admitida em nosso ordenamento, mas que por sua condição precarizante deve ser compatibilizada com a ordem constitucional, em especial com os princípios da dignidade da pessoa humana e do valor social do trabalho e livre iniciativa.

Published: July 2019

Eine zentrale sportpolitische Frage im deutschen Profifußball ergibt sich aus der Diskussion um die Aufhebung der 50+1-Regel: Sollten professionelle Fußballklubs in Deutschland weiterhin von Vereinen oder von Investoren_innen kontrolliert werden? Vor dem Hintergrund des Stakeholder-Ansatzes erscheinen die bisherigen Untersuchungen der Perspektiven von Fußballklubs und Fußballfans von besonderer Bedeutung. Unberücksichtigt blieben bislang die Investoren_innen als Stakeholder-Gruppe. Aufgrund der Begrenzung ihres Einflusses durch die Regel, der damit einhergehenden unmittelbaren Betroffenheit sowie der zunehmenden Bedeutung von Investoren_innen im deutschen Profifußball werden erstmalig die Perspektiven von Investoren_in-nen zur 50+1-Regel und deren Zukunft aufgezeigt. Basierend auf den empirischen Ergebnissen werden Gemeinsamkeiten und Unterschiede der Perspektiven zwischen Fußballklubs, Fußballfans und Investoren_innen aufgedeckt. Sie bilden eine Diskussionsgrundlage, um eine zukünftige Entscheidung hinsichtlich einer Beibehaltung oder Aufhebung stakeholderorienwtiert beurteilen zu können.

In today’s uncertain and ambiguous business reality, both business enterprises and other societal human organizations strive for competitive advantage. To attain it, they develop the capability to pursue innovation, while exploiting other existing capabilities pertinent to their organizational ‘ambidexterity’. This article investigates the role that organizational ambidexterity plays in the relation between intellectual capital (IC) and competitive advantage (CA). Tested is a set of research hypotheses, using sample data gleaned from 233 textile firms in Pakistan. Partial least squares structural equation modeling (PLS-SEM) unconceals a significant mediately effect that organizational ambidexterity interposes between intellectual capital and competitive advantage, i.e., IC helps firms become ambidextrous in attaining competitiveness. Noted too are the significant effects of all three IC components on competitive advantage, whereby the highest effect is attributed to human-development capital (HDC), followed by structural capital (SC) and relational capital (RC). These results contribute to much-needed comprehensive-strategy designs that, based on both intellectual capital and ambidexterity, yield a sustainable competitive advantage. Despite the study’s limitations and small sample size, the article offers both future-research directions and policymaking recommendations.

Recent studies demonstrate that peripheral amylin treatment reduces pathology in mouse models of Alzheimer’s disease (AD). However, soluble and aggregated amylin are distinct species; while amylin is a physiological neuropeptide, amylin aggregation is a pathological factor for diabetes. We thus hypothesized that because of their similarity in secondary structures, amylin antagonizes amyloid-β peptide (Aβ)-induced AD pathology in neurons with a dose-dependent pattern. To test the hypothesis, we conducted both in vitro and in vivo experiments with different doses of amylin and with its analog, pramlintide. Here we report that a high concentration of either Aβ or amylin alone induced tau phosphorylation (pTau) in primary neurons. Interestingly, with a low concentration, amylin had direct effects to reverse the Aβ-induced pTau, as well as damaged neuronal synapses and neurite disorganization. However, when the concentration was high (10.24 μM), amylin lost the effects against the Aβ-induced cellular AD pathology and, together with Aβ, worsened tauopathy in neurons. In the 5XFAD AD mouse model, daily peripheral amylin treatment with a low dose (200 μg/kg) more effectively reduced amyloid burden, and increased synapse, but with a high dose (800 μg/kg), it more effectively reduced tauopathy. Correspondingly, amylin treatment improved learning and memory in these mice. It demonstrates that amylin has a dose-dependent U-shape effect against AD pathogenesis. Within a physiological range, amylin is a neuroprotective hormone against AD in neurons; but when both Aβ and amylin concentrations are elevated, imbalance of Aβ and amylin may contribute to brain AD pathogenesis.

Published: July 2019

Background:

Alzheimer’s disease and dementia are an increasing burden affecting more than 50 million patients worldwide. Hence, research has increased significantly in recent decades. It is recognized that female authors are systematically underrepresented in research in general.

Objective:

In this article, we examine gender disparities in academic research on dementia and Alzheimer’s disease in the last decade.

Methods:

104,858 male and female authorships from 37,961 original research articles were analyzed. The global and country-specific distribution of women across first, co, and last authorships was determined with the inclusion of a citation and productivity analysis.

Results:

42.1% of all authorships and 50.2% of the first, 42.2% of the co, and 32.8% of the last authorships were held by women. Women were less commonly cited, published fewer articles and were also less likely to secure prestigious authorships in articles with multiple authors compared with men. Distinct differences were observed among the countries.

Conclusion:

Substantial growth in the number of prestigious female authorships has been observed to date and is predicted to continue in the future, with an emphasis on the progressive representation of women and a diminishing gender gap.
Cognition Mediates the Relationship Between Sensory Function and Gait Speed in Older Adults: Evidence from the English Longitudinal Study of Ageing

Published: July 2019

Background/Objective:

Gait speed is an important indicator for assessing overall health status. Previous studies have reported the important role of sensory function in gait speed; however, the underlying mechanism is still unclear. This study aimed to examine whether cognition mediates the association of sensory function with gait speed among English older adults.

Methods:

Gait speed was assessed by “timed walking test”. Hearing was measured by using a hearing screening device. Vision was self-reported. Cognition was assessed by questionnaire. Baron and Kenny’s causal steps method and Sobel test were used to examine the mediating effect.

Results:

Among 4,197 participants aged 60 years and older, 13.5% had poor hearing and 12.6% had poor vision, 2.6% had both poor hearing and poor vision. Multiple linear regression models suggested that poor hearing (β= – 1.905, p < 0.001), poor vision (β= – 1.309, p = 0.004), and poor dual sensory function (β= – 2.442, p = 0.013) was associated with worse cognition. Cognition was correlated with gait speed (β= 0.004, p < 0.001). Poor hearing (β= – 0.072, p < 0.001), poor vision (β= – 0.031, p = 0.029), and poor dual sensory function (β= – 0.081, p = 0.011) was associated with slower gait speed. After introducing cognition into the models, regression coefficients between sensory function and gait speed decreased (β= – 0.066, p < 0.001 for hearing; β= – 0.027, p = 0.054 for vision; β= – 0.073, p = 0.020 for combined hearing and vision). Sobel test identified the significant mediating effect of cognition on the association between sensory function and gait speed.

Conclusion:

Cognition partially mediates the association between sensory function and gait speed. Efforts to maintain mobility performance in older adults should consider protecting both sensory function and cognition.
Voltage feedback based flux-weakening control of IPMSMs with fuzzy-PI controller

Published: July 2019

As the traditional flux-weakening control strategies have some limitations, such as poor parameter robustness, non-ideal dynamic performance in the constant power region and so on, a new control strategy based on the formula-based feedforward control and the voltage feedback control is proposed. In this strategy, the given reference values of the flux-weakening currents are first calculated by the simplified formulas used in feedforward control, improving the processing speed of the controller by reducing the computational complexity. Then the reference value of the d axis current is compensated by the fuzzy-PI feedback controller, avoiding operating point drifts caused by the change or inaccurate of parameters in the actual. On this basis, a switching strategy is proposed to achieve a smooth switching between the constant torque and the constant power operation region. The experimental results show that the proposed control strategy has excellent performances, such as strong robustness to parameter perturbation, ideal dynamic performance in the flux-weakening region, smooth switching between the operation regions and so on.

Authors: Piechowiak Tomasz , Balawejder Maciej
Published: July 2019

BACKGROUND:

Ozonation is promising method for prolonging the postharvest shelf life as well as decrease of microbiological contamination and pesticide residue in soft fruit. In view of the fact, that ozone is a substance that can induce the reactive oxygen species generation in plant cells, it is necessary to determine the effect of ozone treatment on the antioxidant status in fruit.

OBJECTIVE:

The purpose of this study was to investigate the impact of ozonation on the antioxidant status in blackcurrant fruit.

METHODS:

Blackcurrants were exposed to ozone at the concentration of 16 mg L–1 and 160 mg L–1 for 5, 15 and 30 min. Changes in antioxidant activity, total phenolic content and activity of selected antioxidant enzymes after ozonation were analyzed.

RESULTS:

It was found, that under proposed conditions the activity of enzymes involved in scavenging of reactive oxygen species (quaiacol peroxidase, ascorbate peroxidase and catalase) increased with ozone concentration and treatment time. In addition, the ozone treatment activated the phenylalanine ammonia-lyase, whose an activity showed a strong correlation with total phenolic content and antioxidant activity of blackcurrants.

CONCLUSIONS:

Ozonation process activated a protective mechanisms against occurrence of oxidative stress in blackcurrant fruit.

Published: July 2019

BACKGROUND:

People with severe speech and motor impairment (SSMI) often depend on electronic user interfaces for communication, learning and many other daily activities. However, these interfaces are often designed assuming the preference and ease of use of end users for different screen regions is the same for people with SSMI as their able bodied counterparts. This paper presents a user study to evaluate whether users can undertake pointing and selection tasks faster if screen elements are organized at their preferred positions.

OBJECTIVE:

To compare pointing and selection times in an eye gaze controlled interface between two conditions – screen elements randomly organized vs screen elements organized according to preference of users in terms of specific screen locations.

METHODS:

We designed a word construction game using familiar 4-letter words and users were instructed to select the correct letters to construct words. We compared total times required to construct each correct word.

RESULTS:

Users with SSMI can statistically significantly construct words faster [F(1,195) [Formula: see text] 31.04, [Formula: see text] 0.01, [Formula: see text] 0.14] when letters were organized at their preferred screen positions than random organization.

CONCLUSIONS:

Users with SSMI prefer middle and right side of screen more than the left side. Pointing and selection times in a gaze controlled interface can be significantly reduced by presenting screen elements at the preferred positions.
