Extrinsic cues, perceived quality, and purchase intention for private labels
Authors: Yan Liu , Xiaojun Fan , Li Jie , Dong Xuebing 
Published: March 2019

Purpose
Based on the cue utilization theory and congruity theory, the purpose of this paper is to investigate the mediating effects of perceived quality on the relationships between category characteristics and purchase intention for private labels.

Design/methodology/approach
To examine the research hypotheses, the authors conducted a questionnaire survey on 703 adult consumers in China.

Findings
The results show that perceived quality fully mediates the relationships between category complexity, risk importance, category quality variation, product signatureness and purchase intention. In addition, consumers’ knowledge moderates the relationship between perceived quality and purchase intention. The implications and future research directions are discussed in this study.

Originality/value
The results show that the category complexity is positively related to consumers’ perceived quality. Although opposite to the conclusions in prior research, the findings are consistent with the unique phenomenon in China, that is, to label the name and location of the contract manufacturers. The authors investigate the moderating role of consumer knowledge, which will provide meaningful guidance for the Chinese retailing market.
Business students’ hardiness and its role in quality of university life, quality of life, and learning performance
Authors: Tho Nguyen Dinh 
Published: March 2019

Purpose
The purpose of this paper is to investigate the impact of the hardiness of university business students. Overall hardiness, and its individual components of commitment, control and challenge, were all explored in relation to students’ quality of university life, quality of life and learning performance.

Design/methodology/approach
A sample of 722 Vietnamese business students was surveyed to collect the data. Structural equation modeling (SEM) was used to determine whether hardiness and/or its components enhanced students’ quality of university life, quality of life and learning performance. Necessary condition analysis (NCA) was then employed to explore the levels of hardiness and its components necessary for each of the key areas.

Findings
SEM results revealed that overall hardiness had a positive effect on all three key areas. In terms of individual components, commitment, control and challenge were found to have positive impacts on learning performance; however, control did not affect quality of university life, and challenge had no effect on quality of life. NCA results show that these components of hardiness had varying degrees necessary for students to experience success in these areas.

Practical implications
Findings suggest that university administers should consider the role which student hardiness, and its individual components, can play in relation to student success at university. Specifically, universities should practice hardiness training and assessment programs to equip their students with hardy attitudes and skills.

Originality/value
This study is one of the first to examine of the levels of the components of hardiness (i.e. commitment, control and challenge) necessary for students to achieve success in the quality of university life, quality of life and learning performance.
Education and employment in two Chilean undergraduate programs
Authors: Espinoza Oscar , McGinn Noel , González Luis , Sandoval Luis , Castillo Dante 
Published: March 2019

PurposeThe purpose of this paper is to determine which of the two variables would be a more reliable proxy for quality of university training: graduates’ satisfaction with their degree program, or institutional prestige.Design/methodology/approachGraduates of professional psychology and teaching programs from three Chilean universities responded to a questionnaire asking their perception of different aspects of their degree program and experiences in their first employment. The three universities differ significantly in the proportion of applicants admitted, and in their prestige.FindingsSalary levels are highly related to profession, but unrelated to graduates’ ratings of quality of curriculum or teaching methods. Overall satisfaction with the university experience is not linked to job satisfaction. Job satisfaction, on the other hand, is highly influenced by salary and secondarily by instructional practices and perceived work relevance of the degree program.Research limitations/implicationsThis study is based on data from 3 of Chile’s 60 universities, and graduates of two programs. Most employment in the two professions is regulated by labor agreements. Generalizability of results is limited. Graduates may not have been employed enough to demonstrate their capacities.Practical implicationsThe findings offer more evidence that prestige ratings are an unreliable indicator of the quality of formation offered by universities. If the government seeks to reduce income inequality, public subsidies of higher education should be based on program quality rather than on institutional prestige.Originality/valueThe findings are directly relevant to the current debate in Chile about what might and what might not help to reduce severe economic inequality.
Small businesses, potentially large impacts
Authors: Mottaleb Khondoker Abdul , Rahut Dil Bahadur , Erenstein Olaf 
Published: March 2019

Purpose
Constraints associated with public agricultural extension services imply that farmers increasingly rely on input providers for agricultural innovations and knowledge. Yet such providers are typically commercial profit-making agents and may have an incentive to suggest relatively costly inputs and/or high rates. The purpose of this paper is to look into the case of Bangladesh and the role of fertilizer traders in terms of farmers’ decisions on which fertilizer to apply and at what rate. Using primary data, the authors examine farmers’ chemical fertilizer use and the associated rice production efficiency, based on different information sources (fertilizer traders, government extension agents or own/peer experience).

Design/methodology/approach
Using primary data, the present study estimates an ordered probit model and production functions separately based on whether or not a farmer relied on information from fertilizer traders or own experience and government extension agents, and examines the efficiency score of each type of farmer.

Findings
The findings demonstrate that the resource-poor farmers rely more on traders’ suggestions for fertilizer application than public extension – but the actual fertilizer information source has no significant effect on the production efficiency of the rice farmers. This study, therefore, does not find exploitative behavior of fertilizer traders. Thus, this study concludes that small rural traders in Bangladesh are working as agricultural extension agents and provide necessary fertilizer application information to resource-poor farmers.

Research limitations/implications
This is a case study based on Bangladesh – an emerging economy in South Asia. The findings of the study may not be generalized for other countries.

Originality/value
To the authors’ knowledge, this is the first study that confirms the role of agricultural input sellers as the extension agent in developing countries.
Impact of television on nutritional intake in communal dining room settings among those with acquired brain injury: A pilot study
Authors: Hall Caitlin , Vivanti Angela , Abbey Karen 
Published: March 2019

AimThose with acquired brain injury (ABI) experience impairments in executive function, attention and concentration that may contribute to or exacerbate poor nutritional intakes. This is frequently observed in long‐stay rehabilitation settings. This investigation aimed to identify the specific impact of the dining room television as a factor that exacerbates poor intake and nutritional status among those with ABI.MethodsRoutine meal audits were completed (six television on, six television off) over four non‐consecutive days. Each individual's protein and energy intake per meal and day were assessed, and the differences were examined through paired t‐tests. Dining room decibels were measured, with means, peaks and minimums recorded.ResultsComplete data for 12 meals were collected for seven individuals. Clinically, but not statistically significant increases in 48‐hour protein and energy intake occurred with television off compared with on, including those requiring texture modified diets.ConclusionsThis pilot investigation highlights that television may have a detrimental impact on nutritional intakes among those with ABI. Given the negligible costs and risk, minimising disruptive influences by turning the television off may become a recommendation for ABI in long‐care rehabilitation settings.

Authors: Dauchy Estelle , Ross Hana 
Published: March 2019

AbstractAimsTo assess the impact of cigarette prices on male smoking initiation and cessation in Kenya from 1960 to 2014.DesignLongitudinal study using individual level data from the 2014 Global Adult Tobacco Survey (GATS) and historical data on cigarette prices.SettingKenya.ParticipantsA total of 2079 men, among whom 619 identified as ever‐smokers.MeasurementsSelf‐reported data on the years of smoking initiation and cessation, merged with historical data on cigarette prices. We employed several methodologies to estimate the effect of prices on smoking transitions, including a pooled linear model with propensity score matching (PSM).ResultsPrice increases were negatively associated with smoking initiation, with price elasticity of initiation ranging from −0.03 (−0.066 to –0.000) to −0.14 (−0.216 to –0.0563). The association was two to three times larger for younger male adults compared with the average. Price increases were correlated with increased cessation for younger males, with a price elasticity of 0.08 (0.027–0.141) and for low‐income males with a price elasticity of 0.16 (−0.752 to 0.429).ConclusionsCigarette price increases in Kenya between 1960 and 2014 were negatively associated with males' smoking initiation and positively associated with younger and lower‐income males' cessation.
Living for Today or Tomorrow? Self‐Regulation amidst Proximal or Distal Exercise Outcomes

Published: March 2019

BackgroundAlthough health promotion efforts to increase exercise behavior often emphasise long‐term outcomes, sustained action in service of a distal reward is challenging. These studies examined how focusing on the proximal benefits of exercise, compared to distal outcomes or more general outcomes, may strengthen individuals’ self‐regulatory self‐efficacy and support physical activity or exercise behavior.MethodsParticipants in Study 1 (N = 1057 community members) completed an online survey. Participants in Study 2 (N = 69 students) and Study 3 (N = 107 students) experienced experimental manipulations related to proximal or distal outcomes of exercise, and then completed survey measures. In Study 4, new members at a commercial gym (N = 210) completed a survey and had check‐ins recorded over 17 weeks.ResultsIn Study 1, participants who ranked proximal outcomes of exercise as relatively more important than distal outcomes reported more frequent physical activity. In Studies 2 and 3, participants induced to focus on proximal outcomes reported increased self‐regulatory self‐efficacy. In Study 4, valuing proximal benefits predicted sustained exercise behavior (i.e. check‐ins), particularly when fitness goal adherence felt difficult.ConclusionsThose holding increased proximal outcome beliefs reported more activity and greater efficacy to overcome the barriers that derail exercise.
Small logging roads do not restrict movements of forest rats in Bornean logged forests

Published: March 2019

AbstractSelective logging is driving the proliferation of roads throughout tropical rain forests, particularly narrow, unpaved logging roads. However, little is known about the extent of road edge effects or their influence on the movements of tropical understory animal species. Here, we used forest rats to address the following questions: (a) Does the occupancy of rats differ from road edges to forest interior within logged forests? (b) Do roads inhibit the movements of rats within these forests? We established trapping grids along a road edge‐to‐forest interior gradient at four roads and in three control sites within a logged forest in Sabah, Malaysia. To quantify the probability of road crossing, rats were captured, translocated across a road, and then recaptured on subsequent nights. We caught 216 individuals of eight species on 3,024 trap nights. Rat occupancy did not differ across the gradient from road edge to interior, and 48 percent of the 105 translocated individuals crossed the roads and were recaptured. This proportion was not significantly different from that of rats returning in control sites (38% of 60 individuals), suggesting that small roads were not barriers to rat movements within logged forests. Subadults were significantly more likely to return from translocation than adults in both road and control sites. Our results are encouraging for the ecology of small mammal communities in heavily logged forests, because small logging roads do not restrict the movements of rats and therefore are unlikely to create an edge effect or influence habitat selection.

Published: March 2019

AbstractLimitations of the ablation index backgroundAblation index (AI) is a novel marker of lesion quality from radiofrequency (RF) catheter ablation. However, AI reliability has not been fully validated by experimental data. The aim of the present study is to validate AI reliability for estimating lesion size using different settings for RF parameters: contact angle, power delivery, and contact force (CF).Methods and resultsWe evaluated the lesion size in porcine hearts (N = 108) after RF application at three different contact angles to the myocardium: perpendicular (90°), oblique (45°), and parallel (0°). At each angle, RF power at 25, 30, and 35 W was applied at target CF values of 5, 15, and 30 g as measured by the CF sensor to reach target AIs of 300, 400, 500, and 600. AI value was significantly correlated with lesion depth, width, and volume (R = 0.84, 0.82, and 0.87, respectively, all P < 0.001). Lesion depth decreased with smaller contact angles (45° and 0°). Furthermore, high‐power RF energy (35 W) resulted in a significantly smaller lesion volume compared with standard‐power energy (30 W). There were no significant differences in lesion size among CF settings.ConclusionsAI was strongly correlated with lesion depth, width, and volume, but only within a small range of contact angles and RF power delivery settings.

Published: March 2019

AbstractThe cowpea aphid,Aphis craccivora,is a major insect pest of cowpea in Africa. Volatile organic compounds (VOCs) mediate plant–arthropod interactions that could be used in the management of insect pests. In this study, we established the VOC profile involved in the interaction betweenA. craccivoraand four cowpea cultivars, namely Ex‐Luanda, Katumani 80, Machakos 66 and Ken Kunde 1. Behavioural assays were conducted to study host preference and gas chromatography‐mass spectrometry (GC/MS) for chemical analysis of volatiles. In preference assays, alateA. craccivorahad no significant preference for any of the four cowpea cultivars tested. However, in the olfactometer assays, the aphids showed a significant preference for odours from cultivar Ex‐Luanda compared to Katumani 80. Machakos 66 and Ken Kunde 1 elicited neutral responses. In pairwise comparisons, alateA. craccivoradid not distinguish between odours of respective cowpea cultivars. GC/MS analysis identified 23 compounds in the volatiles of the four cowpea cultivars. Not all compounds were detected in all cowpea cultivars, and the detected compounds amounts varied in each cultivar. Of these, only four compounds (hexanal,(E)‐2‐hexenal, 1‐octen‐3‐ol and p‐xylene) were emitted in significantly different quantities in the four cultivars. A blend of hexanal and(E)‐2‐hexenal added to cowpea cultivar Ex‐Luanda decreased its attractiveness toA. craccivoracompared to the control. Our findings showed differential attractiveness of VOCs of cowpea cultivars toA. craccivora,suggesting that VOCs could be used in the management ofA. craccivora.
Long‐Term Care Insurance With Family Altruism: Theory and Empirics
Authors: Klimaviciute Justina , Pestieau Pierre , Schoenmaeckers Jérôme 
Published: March 2019

AbstractThis article studies long‐term care (LTC) insurance in the presence of family altruism. We first explore whether family solidarity affects the application of Arrow's (1963) deductible theorem, shown to apply in models without family in earlier work. We find that Arrow's theorem generally holds, but departures from the standard model exist. Our analysis highlights complex interplay between parents’ insurance and children's aid, implying that some intuitive conjectures are not always verified. For instance, while one expects deductible to increase with children's altruism, this is unambiguously confirmed only under certain conditions. We then study empirically the relation between LTC insurance and children's altruism using data from “Health and Retirement Study” (HRS).
Taste‐Based Discrimination, Tolerance and the Wage Gap: When Does Economic Freedom Help Gay Men?
Authors: Christafore David , Leguizamon Susane 
Published: March 2019

SummaryAlthough gay men have reported experiencing labor market discrimination, re‐ search studies on a potentially discriminatory wage gap have reported mixed findings. We consider the Becker model of taste based discrimination which hypothesizes that we will observe, in the presence of discrimination, a smaller or non‐existent wage gap in more competitive markets. Using economic freedom at the state level as a measure of market competitiveness, and controlling for other influential characteristics, we analyze the wages of over 300,000 men in the United States to consider how economic freedom influences the wage gap between cohabitating gay men and married straight men be‐ tween the years 2000 and 2014. We find evidence consistent with model predictions in the presence of labor market discrimination for the states in the South and regions with the highest concentrations of religious households but not in the Northeast, West and less religious regions. Given the lower levels of public support of gay rights in the South and religious regions, this result suggests that gay men may be experiencing la‐ bor market discrimination in these regions but not in regions which typically offer more public support. These findings may help reconcile contradictory findings in previous research which did not explicitly allow for differential regional and religious influences.

SummaryIn a number of compatible plant‐bacterium interactions, a rise in apoplastic Ca2+ levels is observed, suggesting that Ca2+ represents an important environmental clue, as reported for bacteria infecting mammalians. We demonstrate that Ca2+ entry in Pseudomonas savastanoi pv. savastanoi (Psav) strain DAPP‐PG 722 is mediated by a Na+/Ca2+ exchanger critical for virulence. Using the fluorescent Ca2+ probe Fura 2‐AM, we demonstrate that Ca2+ enters Psav cells foremost when they experience low levels of energy, a situation mimicking the apoplastic fluid. In fact, Ca2+ entry was suppressed in the presence of high concentrations of glucose, fructose, sucrose or adenosine triphosphate (ATP). Since Ca2+ entry was inhibited by nifedipine and LiCl, we conclude that the channel for Ca2+ entry is a Na+/Ca2+ exchanger. In silico analysis of the Psav DAPP‐PG 722 genome revealed the presence of a single gene coding for a Na+/Ca2+ exchanger (cneA), which is a widely conserved and ancestral gene within the P. syringae complex based on gene phylogeny. Mutation of cneA compromised not only Ca2+ entry, but also compromised the Hypersensitive response (HR) in tobacco leaves and blocked the ability to induce knots in olive stems. The expression of both pathogenicity (hrpL, hrpA and iaaM) and virulence (ptz) genes was reduced in this Psav‐cneA mutant. Complementation of the Psav‐cneA mutation restored both Ca2+ entry and pathogenicity in olive plants, but failed to restore the HR in tobacco leaves. In conclusion, Ca2+ entry acts as a ‘host signal’ that allows and promotes Psav pathogenicity on olive plants.

AimThe cognitive impairment seen in Parkinson's disease (PD) results in patient disability and reduced quality of life. However, using cognitive screening scales specific to PD in routine clinical practice is difficult because of limited time, resources, and skills. We studied the ability of routine cognitive tests to differentiate between Parkinson's disease dementia (PDD) and PD and among the neuropsychological profiles of elderly individuals with PD, PDD, Alzheimer's disease (AD), and normal cognition.MethodsThis cross‐sectional study involved 124 subjects. Subjects were 35 cognitively normal elderly and 37 elderly individuals with PD, 22 with PDD, and 30 with AD. All subjects were diagnosed by a specialist using standard criteria. Clinically relevant data and scores from the Montreal Cognitive Assessment and the Thai Mental State Examination were collected. Cognitive test scores were compared among groups. Receiver operating characteristic curves were constructed for a range of cut‐off points to explore the sensitivity and specificity of the screening tools to detect PDD.ResultsThere were 74 female subjects (59.7%), and the average age of all subjects was 75.6 years. The median score on the modified Hoehn and Yahr scale was 2.5 in subjects with PD and 4 in those with PDD (P < 0.001). The cut‐offs for differentiating PDD from PD were 25 on the Thai Mental State Examination and 14 on the Montreal Cognitive Assessment. The sensitivity of the Thai Mental State Examination was 78.4%, and the specificity was 66.7% (area under the curve: 0.828). The sensitivity of the Montreal Cognitive Assessment was 81.1%, and the specificity was 75% (area under the curve: 0.876). There was a significant difference in the memory and language subdomains between AD and PDD (P < 0.05).ConclusionsThe cut‐offs used to differentiate PDD from PD were not the same as routine cut‐offs in distinguishing AD from normal elderly. The cognitive profile deficit in PDD differed from that in AD. Interpretations of positive screenings test should take this finding into consideration.
