CUSTOMER CONCENTRATION AND EXPLORATORY INNOVATION: THE MEDIATING EFFECT OF PERCEIVED PERFORMANCE-REDUCING THREATS

A great deal of research attention has been devoted to studying the effects of customer concentration on firm strategic acts. Scholars have also investigated the relationship between customer concentration and firm innovation, but concluded inconsistent findings of such relationship. Furthermore, the underlying mechanism remains unclear. To address these concerns, this study decouples exploratory innovation from firm innovation and introduce performance-reducing threats perceived by the executives as the mediator. Based on the observations of China high-tech listed firms from 2011 to 2018, empirical results show that customer concentration has a U-shaped relationship with exploratory innovation, via the mediating effect of performance-reducing threats perceived by the executives.
Expanding Student Success: The Impact of a Comprehensive College Transition Program on Psychosocial Outcomes

Abstract This study examines the impact of a comprehensive college transition program, the Thompson Scholars Learning Communities (TSLC), on psychosocial outcomes using an experimental design. We estimate overall and heterogenous effects of program participation on students’ sense of belonging to campus, feelings of mattering to campus, sense of academic self-efficacy, and sense of social self-efficacy. Participation in TSLC, as compared to receiving a substantial college scholarship without comprehensive support, leads to large increases in both mattering and sense of belonging to campus during students’ two years in the program. We find no impact of TSLC participation on students’ academic or social self-efficacy. We demonstrate the program effects on students’ feelings of mattering to campus were largest for traditionally underrepresented student groups; however, we find no evidence of heterogeneous effects on students’ sense of belonging to campus, academic self-efficacy, or social self-efficacy. Our findings suggest that comprehensive college transition programs can promote students’ psychosocial outcomes.
Incubation temperature effects on some hatching parameters of silver rasbora (Rasbora argyrotaenia) egg

ABSTRACT This study aims to observe the effects of incubation temperature on some hatching parameters of silver rasbora (Rasbora argyrotaenia) egg and determine the optimum temperature to incubate it. A total of 2,000 fertilized eggs were assigned to 20 incubation cylinder plastic tanks (10 L capacity; 30 cm diameter). Every five tanks were placed in four different containers (120 × 80 × 46 cm3) with incubation temperature treatment including 25.0°C–30.0°C (room temperature), 28.0°C, 30.0°C, and 32.0°C. The increase of temperature caused accelerated hatching time, yolk absorption time, and larvae development; it also increased the yolk absorption rate and larvae abnormality rate. A decrease in hatching and survival rate occurred at the highest temperature treatment, so the optimal incubation temperature for silver rasbora egg is 30°C based on the best results of the total hatching rate and survival rate of larvae.
Crisis information, communication strategies and customer complaint behaviours: the case of COVID-19

Purpose The outbreak of the COVID-19 pandemic plunged global tourism into a huge crisis in 2020. China was confronted with a wave of cancellations by tourism consumers due to COVID-19 and tourist complaints rose dramatically during this period. Although tourism enterprises have quickly introduced measures in response, the effectiveness of targeted policies is expected to be evaluated. Concerned about this phenomenon, this study aims to provide insights into the dim prospects of the tourism industry and to bridge the gap between tourists and enterprises. Design/methodology/approach The current study adopts a two-step method that combines automatic and manual content analysis to contrastively analyse 647 complaints from the Sina platform and the measures of five online travel agencies (OTAs) taken to deal with COVID-19. Findings The results reveal that the COVID-19-related information and policies issued by official departments had a promoting effect on tourist complaints. OTAs were the main target of complainers, and three themes of complaints were identified, namely, cancellation barriers, refund barriers and customer relationship management. Although tourism enterprises’ policies covered most dimensions of the three themes, more detailed and mutually beneficial policies need to be formulated in the face of a new round of cancellations. Originality/value This research attempts to investigate tourism customer complaint behaviours in the case of COVID-19 and to provide tourism enterprises receiving different complaints with practical insights into crisis management. It contributes to simultaneously minimizing business losses and maintaining customer relationships in the service industry, improving the industry’s performance under potential crises in the future.
Does mixing livestock farming enterprises improve farm and product sustainability?

ABSTRACT Mixed farming systems are gaining interest both as a risk management strategy and to apply agroecological principles. This study set out to assess the sustainability of mixed systems compared to their specialized counterparts. The Orfee bioeconomic farm model was used to simulate three mixed farms: beef and dairy, beef and sheep, and cash crop and beef, under 1990–2017 prices and policies in France. Several sustainability criteria were computed at two scales (i) aggregated farm level, to assess whether mixed farms with several integrated enterprises performed better than if these enterprises were managed in specialized farms, and (ii) unit of product or labour to assess whether a product was produced more sustainably and a worker obtained higher and more stable income in a mixed farm. We found that mixed farms had less work peaks, lower global warming potentials and nitrogen balances, lower total production costs, higher and more stable net incomes than if their enterprises were managed in two specialized farms. However, profitability and income variability of the mixed farms were not better than the best performing specialized farm. The consumption of concentrate feed decreased in the mixed livestock farms but increased in the beef-crop farm that degraded feed-food competition.
Educación financiera basada en el bitcoin y la inclusión en planes de estudio

The development of technologies has impacted various sectors of human life. Of course, education is no exception. Since 2009 to date, the concept of cryptocurrency has been all the rage worldwide, specifically bitcoin, which uses blockchain technology, an open source code to operate without a central authority or bank. The purpose of this research was to determine the lag that exists in the curricula in the areas of financial, administrative, accounting and tax education at the higher education level with respect to this topic. Under a deductive method, a sample of students from the School of Public Accounting of the Benemerita Universidad Autonoma de Puebla were surveyed in order to obtain data to determine the interest and needs of bitcoin users. As part of the conclusions, the restructuring of study programs is urged, taking into account the incorporation of concepts related to cryptocurrencies, in order to comply with the training of professionals prepared for the demands of today's market.
Correlation of Glycosylated Hemoglobin and Complexity of Coronary Artery Disease among Aged ≥45 Years Population with Diabetes Mellitus

Objective: Cardiovascular diseases are 1.7 times more prevalent in patients with diabetes mellitus. The aim behind this study was to examine the correlation of glycosylated hemoglobin and complexity of coronary artery disease among middle aged population with diabetes mellitus Patients and Methods: This was a clinical prospective hospital-based comparative study carried out in the department of the cardiology department of Isra University Hospital Hyderabad for 10 months. 153 participants with diabetes mellitus having age ≥45 years both male and female and undergoing their first coronary angiography were included. Data were entered and analyzed by using Statistical Package for the Social Sciences version 21.0. Results: A total of 153 patients were finally analysed. Patients were divided into two groups; group I (HbA1c <6.5%, normal) and group II (HbA1c >6.5%, impaired). The mean age was slightly higher in group II 54.60 as compared to group I 53.65 years, respectively. The Syntax score was Original Research Article Memon et al.; JPRI, 33(31B): 79-85, 2021; Article no.JPRI. 69867 80 correlated with HbA1c levels in patients older than 45 years of age (r = 0.001; p >0.05). Moreover, the higher HbA1c levels were observed in every three categories of Syntax score but they were insignificantly associated with each other in patients with diabetes mellitus and having age more than 45 years. Conclusion: The HbA1c is insignificantly correlated with the complexity of coronary artery disease in diabetic patients having age more than 45 years. While only two factors, hypertension and increased triglycerides are significantly different among the HbA1c groups.
Regulation of the stress-activated protein kinase pathways in hematopoietic cells

The regulation of the p38 mitogen-activated protein kinase (MAPK) and c-Jun N-terminal kinase (JNK) pathways in hematopoietic cells is largely uncharacterized. We demonstrated the tyrosine phosphorylation and activation of p38 MAPK by interleukin (IL) -3, granulocytemacrophage colony-stimulating factor (GM-CSF) and Steel locus factor (SLF). We also showed the activation of p38 MAPK is required for the activation of MAPKAP kinase-2 by these cytokines. The activation of JNK often parallels the activation of p38 MAPK. We found that these cytokines also activated the 46 and 55 kDa splice variants of JNK1 and JNK2, and induced threonine phosphorylation of MAPK kinase 4 (MKK4), an upstream activator of JNK. Together, these results demonstrated that p38 MAPK and JNK are activated not only by environmental stresses, but also by hematopoietic growth factors. In contrast, a related cytokine IL-4 failed to activate p38 MAPK, MAPKAP kinase-2, JNK1, JNK2 or MKK4. Therefore, IL-4 was unique in failing to activate any MAPK pathways in hematopoietic cells. Both SLF and GM-CSF activated JNK comparably with similar kinetics, however SLF induced greater phosphorylation of MKK4 than GM-CSF, suggesting the existence of other JNK kinases. A cDNA with homology to MKK4 was identified in the Expressed Sequence Tag database, and the full-length cDNA was cloned using Rapid-Amplification of Cohesive Ends (RACE) PCR. This cDNA encoded a 419 amino acid protein, hereafter termed MKK7, that contained a putative kinase domain. We identified several splice variants of MKK7, and transcripts encoding MKK7 were expressed ubiquitously. Co-expression of MKK7 with either JNK1 or p38a2 MAPK led to the activation of JNK1, but not p38a2 MAPK. Epitope-tagged MKK7 was activated by IL-3, TNFa, UV light, hyperosmolarity, heat shock and anisomycin, but not by IL-4 or EGF. We also showed that endogenous MKK4 and MKK7 were activated by IL-3, TNFa or the Fc receptor for IgG. MKK7 was also activated by constitutively-active Rac and Cdc42 when expressed in HeLa or Ba/F3 cells. In contrast, constitutively-active Ras activated MKK7 in HeLa cells, but not in Ba/F3 cells, demonstrating that signalling from Ras to MKK7
The Income-related Distribution of Cognitive Function and Its Mobility Among the Chinese Elderly Over 14 Years

Background:With population aging, cognitive function among the elderly has been growing public health concern in China. This study aimed to investigate the trend of income-related inequality in cognitive function, and to track the health-related income mobility among the Chinese elderly. Methods: The data were drawn from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2005, 2008, 2011, 2014 and 2018, with a sample of 10203 Chinese aged 65 and older. The cognitive function was evaluated by the Mini-Mental State Examination (MMSE). The cross-sectional and longitudinal concentration indices were used to measure the magnitudes of inequalities at different length of time. The mobility index was used to capture the discrepancy between the short-term and long-term measures. The contribution of determinants to mobility was estimated by decomposition analysis. Results:The results showed that, the cognitive function among the Chinese elderly scored 21.13 at the baseline. Men, activities, daily living ability, education, marriage status, income, community service, vision and hearing condition were positively associated with cognitive function, whereas age, negative well-being and drinking were negatively associated with cognitive function. The cross-sectional concentration index was positive and significant only at the baseline. In the long run, however, the concentration indices were all positive and became larger over time. After five waves, the mobility reached -4.84. The largest negative contributor to the mobility index was daily living ability, followed by relaxing activity, domestic activity and hearing condition. The two largest positive contributors were negative well-being and income. Conclusion:Our study found that, as a whole, the cognitive function was not performed well among the Chinese elderly. In the long term, the weighted cross-sectional concentration indices underestimated the inequality in cognitive function and good cognitive performance was concentrated more among the rich. When formulating intervention measures, the Chinese government could give priority to vulnerable groups, especially the elderly who are poor or downwardly income mobile.
Worlds apart: Location above‐ or below‐ground determines plant litter decomposition in a semi‐arid Patagonian steppe

While considerable attention has been devoted to how precipitation modulates net primary productivity in arid and semi‐arid ecosystems, the emergence of multi‐faceted controls on carbon (C) turnover suggests that there is much to be understood with respect to the mechanistic controls on plant litter decomposition. In the Patagonian steppe, we conducted a long‐term factorial experiment, evaluating the importance of position, litter quality, tissue origin and soil resources on rates of C turnover under natural field conditions. Leaf and root litter of dominant grass species were placed in litterbags in different positions, on the soil surface and buried at 5‐cm depth, with soil treatments of labile C, nitrogen (N) and their combination (C + N) over a 3‐year period. As predicted, leaf litter decomposed significantly (nearly sixfold) faster above‐ground than did root litter below‐ground (p < 0.001). Surprisingly, root litter decomposed significantly faster than leaf litter above‐ground (p < 0.001), and above‐ground decomposition was not strongly affected by soil resource additions. Below‐ground decomposition was largely determined by the interaction of litter quality and soil resource availability. Determining a C balance by integrating biomass allocation and primary productivity from this field site, combined with the data from this study, suggests large differences between the contribution of the above‐ and below‐ground biomass to soil organic matter (SOM) pools and a long residence time of undecomposed root litter. Synthesis. Litter position clearly emerged as the predominant variable determining C turnover in this semi‐arid steppe ecosystem, with litter quality and soil resources having significant, but more modest, effects. The near complete independence of above‐ground litter decomposition from soil resources and rapid decomposition of surface litter, coupled with the counterintuitive relationships with litter quality, suggests that, in the long term, C loss from photodegradation may result in a minimal contribution of above‐ground litter to SOM formation. These results have mechanistic implications for the distinct functionality of litter decomposition above‐ and below‐ground in semi‐arid ecosystems, and how these differential controls may alter the C balance due to future changes in climate and land use.
The green and the grey: the differing professional development needs of early and mid/late career substance use workers

Abstract The alcohol and other drugs (AOD) sector has shown strong progress with regard to recognition, professionalism and international programs of training and credentialing. Yet little is known regarding the professional development (PD) needs of AOD workers, nor how these needs differ across career stages. Australian AOD workers (N = 812) from the government and non-government sectors completed an online survey. Early career workers (≤3 years’ AOD experience) were more likely than mid/late career workers to be non-government employed and earn less than the national average and were less likely to be AOD qualified and have permanent employment. Early career workers were more likely to nominate a need for PD in advanced clinical skills (86.3%, p ≤ .05), dual diagnoses/mental health (72.6%, p ≤ .001) and service delivery/partnerships/teamwork (66.4%, p ≤ .01). These findings highlight an urgent need for advanced skill development to accord with increasing complexity in AOD presentations. High quality care is founded on a skilled and experienced workforce; addressing the ubiquitous PD barriers of time, cost and access is a crucial workforce development priority best addressed through reform to systems of organisational funding, professional accreditation and curriculum development in AOD specialist and generalist health areas.
Pre-slaughter road transportation times: meat quality and sensory properties of Nellore bull meat

Abstract: This study evaluated the effects of different pre-slaughter road transportation times on sensory evaluation and instrumental measurements of Nellore cattle meat quality. About 15 farms were classified according to transportation times (five farms per transportation time group) as follows: 1 — less than 2 h (<2), 2 — between 2 and 4 h (>2 and ≤4), and 3 — between 4 and 6 h (>4 and ≤6). The experiment was a completely randomized design with 15 replications and three treatments. Meat analyses were performed on steaks taken from the longissimus dorsi muscle from the 10th rib to the third lumbar vertebra. Road transportation times had no significant effects on pH and mean shear force values. Sarcomere length, myofibrillar fragmentation index, and creatine kinase levels were also not affected by transportation time. Furthermore, road transportation times had no effect on meat tenderness, flavour, odour, and overall acceptability when evaluated by consumers. Thus, a pre-slaughter road transportation time up to 6 h does not affect the sensory evaluation and instrumental measurements of Nellore cattle meat quality when raised using a grazing system.
The Moderating Effects of Leader-Member Exchange for Technology Acceptance: An Empirical Study Within Organizations

Within the technology acceptance literature, the issue of top management support and commitment has been studied extensively; however, the issue of leadership per se has not been addressed directly. A missing piece of the leadership puzzle as it relates to technology acceptance is an exploration of how top management support gets translated in the organizational hierarchy. This study introduces leader-member exchange (LMX) to better understand this missing piece. Specifically, this research explores the role direct supervisors play in the acceptance process by end users based on the moderated model of LMX and supervisor influence. The empirical test results in the field setting show that LMX is a significant moderator for most of the technology acceptance variables within organizations. The study explores the role of the quality of the relationship between supervisors and employees as end users. It also highlights the role of LMX and supervisor influence as a conduit for the acceptance process among end users in the organization.
Synthon Hierarchies in Crystal Forms Composed of Theophylline and Hydroxybenzoic Acids: Cocrystal Screening via Solution-Mediated Phase Transformation

Theophylline, a pharmaceutical model compound, was screened for cocrystal formation using nine (di)hydroxybenzoic acids as cocrystal formers, namely, 2-, 3-, 4-hydroxybenzoic- and 2,3-, 2,4-, 2,5-, 2,6-, 3,4-, and 3,5-dihydroxybenzoic acids. The experiments were conducted using an efficient, reliable, and fast screening method based on thermodynamically driven solution-mediated phase transformation and revealed the formation of eight cocrystals and one salt. The theophylline-based solids were identified using powder and structurally characterized via single-crystal X-ray diffraction. The obtained solids are sustained by theopylline-carboxylic acid heterosynthons, in addition to both theophylline and carboxylic acid homosynthons. The results are a part of a systematic study of xanthine-alkaloid cocrystals that aims to establish synthon hierarchies in cocrystals comprised of molecules with multiple hydrogen-bonding functional groups. Structural features and synthon hierachies are discussed and compared to t.
A Novel Iron(III)-Selective Membrane Potentiometric Sensor Based on 5-Chloro-3-(4-(trifluoromethoxy) phenylimino) Indolin-2-one

A novel polyvinyl chloride (PVC) membrane sensor that is highly selective to Fe 3+ ions was prepared by using 5-chloro-3-(4-(trifluoromethoxy)phenylimino)indolin-2-one (CFMEPI) ionophore. The sensor exhibits a Nernstian response for Fe 3+ ions over a wide concentration range (1.0 ×10 -2 −1.0×10 -6 M) with a slope of 46.7±0.5 mV per decade. The sensor has a response time of 20s and can be used for at least 3 months without any measurable divergence in potential. It was concluded that the sensor response was pH independent in the range of 4.0-8.61. The sensor has some advantages such as short analysis time, particularly high se- lectivity towards iron (III). The sensor was used successfully for direct determination of Fe 3+ in several synthetic and real samples with satisfactory results.
