Sport rebranding: the effect of different degrees of sport logo redesign on brand attitude and purchase intention

PurposeDespite its growth, there has been a lack of investigation on how sport rebranding influences fans and their behaviors. This study sought to examine how a critical aspect of rebranding – logo redesign – influences fans' attitudes toward a sport brand and intent to purchase merchandise bearing the rebranded logo. More specifically, we aim to investigate the influence of varying degrees of logo change and fan identification in relation to brand attitude and purchase intention.Design/methodology/approachAn experimental design, 4 (degrees of logo change) × 2 (fan identification: low, high), was utilized with the sample of 277 participants. The current logo of the Ultimate Fighting Championship was redesigned into three fictitious rebranded logos as stimuli based on different rebranding types.FindingsThe results suggest that color change and revolutionary change generate the most negative attitudes from both high- and low-identified fans, and fan identification is not a significant factor influencing fan attitudes. Regarding purchase intention, low-identified fans are not significantly influenced by logo changes whereas highly identified fans showed similar response to their attitudes.Originality/valueThe findings advance the current body of knowledge on sport rebranding and fan behavior by demonstrating the effects of varying degrees of logo redesign and fan identification levels on brand attitude and purchase intention. Moreover, the current research has important implications for sport marketers on developing effective rebranding and logo redesign strategies.
Implementation of a Parallel Fault Simulation System using PODEM in a Hardware Accelerator using Python

VLSI Testing is one of the essential domains in recent times. With the channel length of the transistor decreasing continually, the number of transistors in a chip increases, thus increasing the probability of defects or faults. Automatic Test Pattern Generator is one way to find such input test vectors to the circuit, which will help identify the faults if present. PODEM algorithm is one such algorithm used in this regard. This paper helps in reducing the runtime of this algorithm by the parallelism approach. Different stuck-at faults in the gate level circuit are simulated parallelly.
Online Self-Regulated Learning and Achievement in the Era of Change

As education is remodelled to online solutions, instructors and students are required to adapt their teaching and learning through different forms of monitoring, regulation and assessment. This remodelling requires conceptual and philosophical reflection relating to stakeholder roles and the relationship between learners and teaching materials within digital learning spaces. With a sample of 276 student participants, this article reports from a Japanese university which shifted all regular face-to-face lectures online at short notice during 2020. Self-regulated learning is drawn from to test a primary thesis that online self-regulated learning impacts achievement. It was hypothesized that metacognitive skills provide the foundation for online self-regulated learning but are not able to exert a direct effect on achievement as such skills must be mediated through applied behavioral action. Three criterion models indicated limited achievement effect sizes between 11.1% and 12.6%. The outcomes are discussed in relation to online learning and pedagogies relevant to distance education in the era of change.
Bioresorbovatelné polymery pro zdravotnické aplikace

The presented work deals with the types, properties and utilization of bioresorbable poly-meric materials commonly used in medicinal applications. Firstly, the basic properties of polymeric materials are described followed by the terminology related to bioresorbable polymers, their degradation and resorbtion, respectively. The next chapter discussed the most significant bioresorbable polymers; particularly the synthetic. The last chapter in the-oretical part of this work was dedicated to various applications such as sutures, implants, drug delivery systems, scaffolds for cell growth and materials for wound dressing. In the experimental part, commercial bioresorbable suture materials were studied. Their charac-terization was carried out by scanning electron microscopy (SEM), which was useful for study of their surface. We also investigated the antibacterial properties of chosen material (Vicryl Plus Antibacterial). The concentration of active antibacterial substance (Irgasan) was determined by HPLC and testing of antibacterial activity was also carried out.
The Curcumin Analog Da0324 Inhibits the Proliferation of Gastric Cancer Cells via HOTAIRM1/miR-29b-1-5p/PHLPP1 Axis

Background: Our previous study has shown that Da0324, a curcumin analog, exhibited significantly improved stability and antitumor activity. However, the molecular mechanisms of action of Da0324 remain poorly understood. Long non-coding RNA (lncRNA) has been shown to play a key role in tumor progression. Here, we aim to investigate the molecular mechanisms underlying the anti-cancer activity of Da0324 by regulating the lncRNA HOTAIRM1. Methods: Gastric cancer cell lines were treated with Da0324 and/or transfected with lentiviral vector expressing HOTAIRM1 shRNA, and/or miR-29b-1-5p mimics and/or small interference RNA (siRNA) against PHLPP1, or HOTAIRM1 siRNA or lentiviral vector expressing HOTAIRM1, as needed. The expression of HOTAIRM1, miR-29b-1-5p and PHLPP1 in GC cells was determined by Real-Time PCR. Cell growth was examined by CCK-8 assay and colony formation assay in vitro. The targeted relationship between HOTAIRM1 and miR-29b-1-5p was verified by luciferase reporter gene assay. PHLPP1 protein expression was examined by Western blotting. Results: Da0324 increased the expression of HOTAIRM1 in GC cells. HOTAIRM1 expression was significantly down-regulated in GC tissues, and the low expression of HOTAIRM1 was associated with the shorter survival rate of GC patients based on the TCGA database. Knockdown of HOTAIRM1 promoted GC cell proliferation whereas overexpression of HOTAIRM1 inhibited GC cell proliferation as demonstrated by CCK-8 and colony formation assays. Moreover, knockdown of HOTAIRM1 reversed the Da0324-mediated growth inhibition of GC cells. Furthermore, HOTAIRM1 acted as a sponge for miR-29b-1-5p and PHLPP1 is regulated by the HOTAIRM1/miR-29b-1-5p axis in GC cells. Overexpression of miR-29b-1-5p or knockdown of PHLPP1 reversed the ability of Da0324 to inhibit the growth of GC cells. Conclusions: Our data suggest that Da0324 exerts antitumor activity by regulating HOTAIRM1/miR-29b-1-5p/PHLPP1 axis in GC cells, and provide new insights into the anti-cancer mechanism of Da0324.
Bisphenol A and its Analogues: Human Exposure and Biological Effects-A Review

The most prevalent exposure of bisphenol A (BPA) to biological systems has directed health organizations to reduce its safe dosage and the stringent regulation by developed countries that led to ban of BPA-based (Bisphenol analogues) baby bottles. This in turn has opened a new window for ongoing entry of bisphenol analogues into consumer market. Recently, there has been tremendous growth in both production and application of bisphenol analogues to achieve the "BPA-free" claim. Nevertheless, due to growing epidemiological evidence concerning the toxicological effects of these bisphenol analogues in both in vivo and in vitro systems, the debate regarding the safety concerns over bisphenols is back. Structural analogues of bisphenol A had been identified in food products, human and environment matrices. Present review is an attempt to recapitulate the presence of bisphenols in food and environment matrices as well as their concerning physiological effects in animal models and human groups. But, due to structural analogy of these substitutes, their endpoints on biological functions are comparable to original compound or in certain situations, more harmful than original compound. Unfortunately, other potentially harmful alternatives are emerging and it is therefore advised that the replacement of bisphenol A with other structural analogues must be executed with great care.
A New IPMSM With Hybrid Rotor Structure for Electrical Vehicle With Reduced Magnet Loss

Aiming at the problem of excessive eddy current loss of permanent magnets in fractional slot concentrated winding permanent magnet synchronous motors (FSCW-PMSM) at high speed, a new PMSM with hybrid rotor structure for electric vehicles (EV) is proposed in the article, the key is to introduce additional ferrite magnets in <inline-formula> <tex-math notation="LaTeX">$d$ </tex-math></inline-formula>- and <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula>-axis magnetic flux paths, respectively. Furthermore, slotting on the rotor surface and genetic algorithm (GA) optimization are adopted to compensate for the side effects caused by the introduction of ferrite magnets and to obtain optimal parameters of the new motor. Compared with the traditional all-Nd-Fe-B structure, the proposed hybrid rotor structure can not only curb the magnet loss at high speed, but also present a cost-effective design approach for interior pemanent magnet synchronous motor (IPMSM) for EV applications with less usage of expensive Nd-Fe-B magnets as well as enhanced reluctance torque capability.
Translanguaging and Minoritized Language Maintenance: Lessons from Indonesia

Translanguaging has been considered as an effective pedagogical approach to foster multilingualism. Previous studies have suggested further that teaching English through pedagogical translanguaging can increase participation of language-minoritized students and thus, promote minoritized language maintenance. However, it remains unclear as to what extent the assumed transformative power of translanguaging allows students to challenge prevailing monolingual ideologies that are gradually pushing minoritized language use to the periphery of society. There is growing evidence that promoting translanguaging practices to language-minoritized students can inadvertently contribute to their language shift from minoritized to majoritized languages (i.e., English and national languages). To maintain and extend this discussion, this article reports on a case study investigating the extent to which translanguaging practices in a tertiary-level EFL class in Indonesia contributes to the efforts to reverse language shift from Javanese to Indonesian and English. The data were drawn from audio-recorded classroom interactions, artefacts of student work and follow-up semi-structured interviews. The findings suggest that translanguaging pedagogy can support minoritized language maintenance only when language inequalities and language hierarchies are transgressed. Furthermore, the effectiveness of translanguaging in maintaining Javanese seemingly relies on whether students have enough proficiency in the Javanese language. Otherwise, the endorsement of translanguaging in this polity may be perceived as an opportunity to practice more dominant languages.

Design and validation of a tennis tool to control on-court technical and tactical training content

In high performance tennis, different aspects like physical-conditioning, strategy-tactic, technical-biomechanical, psychology and skills acquisition have received large attention from the researchers. Nevertheless, the programming, periodization and planning of training sessions and competitions have not been as studied in depth. Coaches still use their experience, trial-error and subjective perceptions as methods of conducting these fundamental tasks. This article presents the design and validation of an instrument to control the technical and tactical training content on-court. The instrument was conceived by 9 experts and validated by 23 experienced coaches, who used on-court tennis exercises examples. The instrument is a useful tool for helping the coaches to improve the control of the on-court technical and tactical content and the tennis training session contents in high performance tennis players.
The effect of biochar on plant diseases: what should we learn while designing biochar substrates?

AbstractThe increasing demand for soilless substrates and rising environmental concerns about the use of non-renewable resources such as peat has led to the search for alternative constituents of growing mixtures for containerized plants. In this report we reviewed the works concerning biochar as constituent of growing media, targeting its influence on plant growth and plant disease. Biochar mostly has positive or neutral influences on plant growth compared with peat media when present in concentrations higher than 25% (v:v). However, studies of biochar influence on plant disease reveals that while lower concentrations (≤1%) of biochar often suppressed several diseases, higher concentrations (≥3%) were mostly ineffective or induced plant disease. For use as horticultural peat replacement, it is recommended that biochar feedstocks and concentrations be standardized and the potential effect of biochar on plant disease be considered, so that growers can rely on consistent and reproducible biochars for desire.
An Educational Study on Gadget Addiction and Mental Health among Gen Z

The acceleration of modern technology in the techno gadget era has led to the transformation of modern media highlighted by Generation Z. The aim of this study is to explore how gadget addiction influences the level of depression, anxiety, stress and sleep quality among the samples from the Ministry of Health Training Institution Sungai Buloh, Malaysia. Using the stratified sampling method, a total of 316 college students from various field are surveyed on the Smartphone Problematic Use Questionnaire, Depression Anxiety Stress Scale and Pittsburg Sleeping Quality Index. The Pearson correlation analysis and linear regression are adopted to find the relationship among the variables. Results show that gadget addiction is a predictor of depression, anxiety, stress and sleep disturbances. The findings of descriptive analysis show that the level of addiction, depression, anxiety and stress among the trainers is high. Positive correlations are found between the gadget addiction and levels of depression, anxiety, stress and sleep quality. Levels of depression, anxiety, stress and sleep quality among trainers are significant, with 13%, 10.7%, 12.5% and 3.4% experiencing symptoms of depression, anxiety, stress and sleeping disturbance respectively. Therefore, it is generally possible to know that the problem of gadget addiction can interfere with mental health of the users if the use of gadgets is not well controlled. The implications of this study are useful to academics and heavy gadget users and those who are hooked with their gadgets in their everyday life. Further studies in this area are needed to delve deeper into other issues related to each element of gadget addiction in order to reinforce the research framework which will in turn develop a standard guide for controlling gadget use in Malaysia.
Synthesis, antimicrobial activities and computational studies of some oxazolone derivatives

Synthesis of the oxazolone derivatives was achieved by the condensation of aromatic aldehydes with N-acetyl glycine in the presence of acetic anhydride and anhydrous sodium acetate. A total of six oxazolones were synthesized and characterized using 1H-NMR, 13C-NMR and FT-IR spectroscopic techniques. The synthesized compounds were screened for their in vitro antibacterial and antifungal activities using streptomycin and ampicillin as control. The result showed that some of the compounds demonstrate good antibacterial activities against specific bacterial strains and moderate activities against other bacterial strains. The compounds did not show any sensitivity against the tested fungal strains. The quantitative structure-antibacterial activity relationship was studied using some quantum chemical parameters with the aid of Spartan 10 (V1.0.1) and XLSTAT (add-in) software. A good correlation was observed between the antibacterial activity of the compounds and the calculated quantum chemical descriptors.Keywords: oxazolones; N-acetyl glycine; antibacterial activity; chemical descriptors.
Combined crossed molecular beams and computational study on the N(2D) + HCCCN(X1Σ+) reaction and implications for extra-terrestrial environments

The reaction of the nitrogen atom (N) in its first electronically excited state (2D) with cyanoacetylene (HC3N) has been investigated under single-collision conditions by using the crossed molecular beam method with mass spectrometric detection at a collision energy of 31 kJ mol−1. With the support of electronic structure calculations, we found that this reaction proceeds via the barrierless addition of the N(2D) atom to the carbon–carbon triple bond of HC3N, followed by the formation of a cyclic intermediate adduct HC(N)CCN, which dissociates to C(N)CCN + H products or isomerises to a more stable intermediate HNCCCN by H-migration and ring-opening processes. The long-lived HNCCCN complex produces the linear 3Σg – ground state dicyanocarbene (NCCCN) radical plus atomic hydrogen through a barrierless unimolecular dissociation accompanied by a negligible competitive channel forming the NCCCN radical (1A1) with a bent C 2v structure plus H. The main product of this neutral-neutral reaction is the 3NCCCN radical that could be a potential precursor to form other nitriles (C2N2, C3N) or more complex organic species in planetary atmospheres, such as that of Titan and Pluto, in cometary comas, and in UV irradiated interstellar environments. GRAPHICAL ABSTRACT
Determining Food Stability to Achieve Food Security

Food security, as part as public health protection, constitutes one of the main objectives for countries aiming to ensure the health of all their citizens. However, food security is compromised worldwide by conflict, political instability, or economic crises, both in developed and developing countries. Conversely, because of the importance of agriculture to the economies of rural areas both in developed and developing countries, this sector can contribute to improving food stability, as well as to furthering food security. Thus, livestock and traditional meat products represent a key factor in ensuring food availability. Overall, biosecurity measures improve animal welfare by decreasing the occurrence of diseases that compromise the stability by causing fluctuations in the availability of meat and animal-derived food products such as milk, eggs, or traditional fermented products. As a consequence, an absence of biosecurity measures affects food security (in its quantitative definition, as described above) as well as the productive, sanitary, and environmental sustainability of the rural environment. Products of animal origin support local trade and the regional economy, while contributing to the availability of foods without great external dependence. The manufacture of foods of animal origin aims to create products that are durable and that maintain food availability for long periods of time, even during seasons with scarce resources. Thus, dry-cured or fermented meat products play an important role in food availability. Food security also refers to food access under healthy economic conditions; therefore, knowledge of the main tools that guarantee the safety of these kinds of food products is essential to achieving food stability and further food security.
The Mixed-Metal Oxochromates(VI) Cd(HgI2)2(HgII)3O4(CrO4)2, Cd(HgII)4O4(CrO4) and Zn(HgII)4O4(CrO4)—Examples of the Different Crystal Chemistry within the Zinc Triad

The three mixed-metal oxochromates(VI) Cd(HgI2)2(HgII)3O4(CrO4)2, Cd(HgII)4O4(CrO4), and Zn(HgII)4O4(CrO4) were grown under hydrothermal conditions. Their crystal structures were determined from single-crystal X-ray diffraction data. The crystal-chemical features of the respective metal cations are characterised, with a linear coordination for mercury atoms in oxidation states +I and +II, octahedral coordination spheres for the divalent zinc and cadmium cations and a tetrahedral configuration of the oxochromate(VI) anions. In the crystal structures the formation of two subunits is apparent, viz. a mercury-oxygen network and a network of cadmium (zinc) cations that are directly bound to the oxochromate(VI) anions. An alternative description of the crystal structures based on oxygen-centred polyhedra is also given.
L1 congruency, word frequency, collocational frequency, L2 proficiency, and their combined effects on Chinese–English bilinguals’ L2 collocational processing

Aims: The current study investigated the effects of first language (L1) congruency, word frequency, collocational frequency, second language (L2) proficiency, and their combined effects on L2 collocational processing. Methodology: Twenty English native speakers and 60 adult Chinese–English bilinguals (intermediate and advanced) completed an online phrasal decision task. They made a judgment about whether target word pairs (congruent collocations, incongruent collocations, and non-collocational baseline items) were commonly used in English. Data and analysis: Response time and accuracy data were analyzed with mixed-effects models, with focus on the interactions of the variables of interest. Findings: Results demonstrated differential effects for the response time and accuracy data: (1) both L2 groups were significantly more accurate but not significantly faster in judging the congruent collocations than the incongruent collocations, and unexpectedly similar patterns were observed with the L1 group; (2) all participants were sensitive to word frequency and collocational frequency, but they differed in the manner and degree of such sensitivity; and (3) the processing of incongruent collocations showed greater combined effects of word frequency and collocational frequency than did the processing of congruent collocations. Originality: We specifically investigated the effects of multiple influencing factors and their combined effects. In addition, we addressed a methodological limitation regarding stimuli control by using congruent and incongruent collocational pairs that differed in only one constituent word. Implications: Our findings highlight the non-colinear relationship of L2 proficiency and (explicit and implicit) collocational knowledge as well as the semantic aspects of cross-language differences, and they also support the usage-based models.
A Sub-6G SP32T Single-Chip Switch with Nanosecond Switching Speed for 5G Applications in 0.25 μm GaAs Technology

This paper presents a single-pole 32-throw (SP32T) switch with an operating frequency of up to 6 GHz for 5G communication applications. Compared to the traditional SP32T module implemented by the waveguide package with large volume and power, the proposed switch can significantly simplify the system with a smaller size and light weight. The proposed SP32T scheme utilizing tree structure can dramatically reduce the dc power and enhance isolation between different output ports, which makes it suitable for low-power 5G communication. A design methodology of a novel transmission (ABCD) matrix is proposed to optimize the switch, which can achieve low insertion loss and high isolation simultaneously. The average insertion loss and the isolations are 1.5 and 35 dB at 6 GHz operating frequency, respectively. The switch exhibits the measured input return loss which is better than 10 dB at 6 GHz. The 1 dB input compression point of SP32T is 15 dBm. The prototype is designed in 5 V 0.25 μm GaAs technology and occupies a small area of 12 mm2.
