Published: October 2020

This study focused on determining the influence of SAEP on knowledge gain in secondary school agricultural education among Form Three students in Migori County, Kenya. It zeroed on analysing the differences in knowledge gained in agriculture between two groups, one taking part in SAEP and the other not taking part. It utilised quasi-experimental design, particularly the pre-test and post-test none-equivalent control group design incorporating a sample of 384 forms three agriculture students in Migori County. A test for measuring learning outcomes was used to collect data before and after the programme. Analysis of data was done using SPSS (Version 22). Descriptive statistics were used to present and describe data while inferential statistics were used test hypotheses at α = 0.05. The study established that there was a statistically significant difference in the acquisition of knowledge of specific agriculture content between secondary school agriculture students exposed to SAEP as opposed to the control group.

Published: October 2020

Background: The prognostic nutritional index (PNI) is a simple metric calculated using serum albumin and the peripheral lymphocyte count. It was reported that a low PNI score is significantly associated with major postoperative complications and poor prognosis. The purpose of the present study was to investigate the effects of perioperative oral management (POM) on the perioperative PNI profiles of patients with digestive system or urinary cancers. Study Design: The medical records of 181 patients with cancer who underwent surgery and for whom a PNI could be calculated were retrospectively reviewed. Results: The intervention rate with POM was 34.8%. The median preoperative PNI score was 48.25 in all patients with a POM intervention [25% to 75% interquartile range (IQR): 44.38–54.13] and 47.25 in those without an intervention (IQR: 42.0–53.5). Compared with patients not receiving POM, those who received POM had significantly higher PNI scores from the early postoperative period (p < 0.05). Notably, of patients who could resume oral intake within 3 days after surgery, those who received POM intervention, compared with those who did not, had significantly higher PNI scores from the early postoperative period (p < 0.05). Conclusions: Perioperative oral management interventions might have positive effects on the postoperative PNI scores of patients with cancer.

Published: October 2020

Background: Phase ii data are increasingly being used as primary evidence for public reimbursement for oncologic drugs. We compared the frequency of reimbursement recommendations for phase ii and phase iii submissions and assessed for variables associated with a positive or conditional recommendation. Methods: We identified submissions made to the pan-Canadian Oncology Drug Review’s Expert Review Committee (perc), of the Canadian Agency for Drugs and Technologies in Health, July 2011 to July 2019, that were supported only by phase ii data. We identified variables within the perc’s deliberative framework, including clinical and economic factors, associated with the final reimbursement recommendation. We conducted a multivariable analysis with logistic regression for these variables: feasibility of phase iii study, hematologic indication, and unmet need. Results: We identified 139 submissions with a perc final recommendation. In 27 instances (19%), the submission had only phase ii evidence, and a positive recommendation was issued for 63% of them (the positive recommendation rate was 82% for submissions with phase iii evidence). Clinical benefit (p < 0.001), unmet need (p = 0.047), and patient alignment (p = 0.015) were associated with a positive recommendation. If a future phase iii study was deemed feasible for submissions with only phase ii evidence, then in univariable (p = 0.040) and multivariable analysis (p = 0.024), the perc was less likely to recommend reimbursement (odds ratio: 0.132). Conclusions: Although more than half the oncologic submissions with phase ii data were recommended for public reimbursement, compared with submissions having phase iii data, they were less likely to be recommended. A positive or conditional recommendation was more likely if clinical benefit and alignment with patient values was demonstrated. The perc was less likely to recommend reimbursement for submissions with phase ii evidence if a phase iii trial was deemed possible.

Introduction: The understanding of the biology and epidemiology of, and the optimal therapeutic strategies for, breast cancer (bca) in younger women is limited. We present the rationale, design, and initial recruitment of Reducing the Burden of Breast Cancer in Young Women (ruby), a unique national prospective cohort study designed to examine the diagnosis, treatment, quality of life, and outcomes from the time of diagnosis for young women with bca. Methods: Over a 4-year period at 33 sites across Canada, the ruby study will use a local and virtual recruitment model to enrol 1200 women with bca who are 40 years of age or younger at the time of diagnosis, before initiation of any treatment. At a minimum, comprehensive patient, tumour, and treatment data will be collected to evaluate recurrence and survival. Patients may opt to complete patient-reported questionnaires, to provide blood and tumour samples, and to be contacted for future research, forming the core dataset from which 4 subprojects evaluating genetics, lifestyle factors, fertility, and local management or delivery of care will be performed. Summary: The ruby study will be the most comprehensive repository of data, biospecimens, and patient-reported outcomes ever collected with respect to young women with bca from the time of diagnosis, enabling research unique to that population now and into the future. This research model could be used for other oncology settings in Canada.

Authors: Sugiyarti Listya , Asmilia Nur
Published: October 2020

One of Mina Kahuripan fish cultivators in Jampang village located in Bogor Regency has innovation and achievements in managing fish and its fish feed, and is the largest fish producer in Bogor Regency. One of the innovations of fish cultivators is the use of a 4G (Four G) fish pond. Besides the fish pond innovation, there is another innovation, namely the use of the Azolla plant. This research aims to analyze the collaboration between Azolla and the 4G pond in waste management scenarios and cycle costing. This research is a qualitative research phenomenon. The data collection technique is done by using observation, interview, documentation, and experiment techniques. Respondents of this study were fish cultivators Mina Kahuripan in Jampang Bogor Village. The results showed that the cycle costing analysis between conventional and 4G fish ponds, it was seen that the production costs in conventional ponds were higher because the media used were all purchased by new categories, while the production costs for 4G fish ponds were lower even though there was a budget for Azolla plant ponds, the quality of the fish produced was guaranteed. Lower production costs are due to the fish cultivators doing waste management from the waste in making 4G fish ponds, resulting in cost efficiency. Another advantage of Waste management scenarios utilizes waste from vegetable and fruit plants that are above the 4G fish pond

Attention extends beyond single words in beginning readers
Authors: Snell Joshua , Cauchi Christophe , Grainger Jonathan , Lété Bernard
Published: October 2020

A common notion is that during the first stages of learning to read, attention is narrowly focused so as to encompass only a single or a few letters. In skilled adult readers, however, attention extends beyond single words. The latter is evidenced by faster recognition of words that have many letters in common with surrounding words, along with correlations between such integration effects and measures of attention. These premises suggest that the distribution of attention gradually increases as a function of reading skill, and that this progression can be mapped by measuring spatial integration effects across the course of reading development. The latter was undertaken in the present study, in which we employed the flanker paradigm combined with the lexical decision task. Children in grades 1―6 (N = 113) were shown central target words flanked by various types of orthographically related and unrelated flanking stimuli. Against expectations, significant effects of flanker relatedness on word recognition speed were found in the youngest children, and this effect was not modulated by reading age. Our results challenge the notion that attention is focused on single letters in beginning readers, and instead suggest that, from the earliest stages of reading development, orthographic processing can extend beyond single words.
On the question of legal warranties when renewing at work
Authors: Kuksin Stanislav
Published: October 2020

Problem setting. The article considers the legal guarantees for the re-employment of employees, their nature and significance, as well as draws attention to case law, in particular, states that employees who believe that their rights have been violated can go to court to protect it. It is emphasized that today the observance of legal guarantees of labor rights of citizens occupies one of the important places in the system of universal values and is a prerequisite for the formation of the state and society, which ensure the human right to a decent standard of living. Because, without an effective system of legal guarantees, it is impossible to ensure the unimpeded exercise of the rights granted to every citizen.
Analysis of recent researches and publications. Issues of social insurance were the subject of research by such scientists as V.M. Andriyiv, S. Ya. Vavzhenchuk, O.O. Duma, M.I. Inshin, O.A. Sytnytska, O.V. Smirnov, O.M. Yaroshenko, and others.
The purpose of the article is to explore the legal guarantees for the renewal of employees, their nature and significance.
Article’s main body. Legal guarantees of labor rights when resuming employment are considered as a separate, independent, legal category, which is a set of general and special legislation means, methods and conditions of implementation, protection and protection from wrongful violations of labor rights, freedoms and interests of employees. It is noted that the reinstatement of an employee as a means of protection contributes to the return of his lost condition – the restoration of labor relations. Implementation of this measure in case of dismissal of an employee without legal grounds or in violation of the established procedure is ensured by the implementation of the law enforcement body of the state – the court – certain actions that are reduced to guaranteeing (compulsory security) the employee’s right to work.
Conclusions and prospects for the development. It is concluded that the legal guarantees of labor rights during reinstatement are designed, above all, to minimize the negative consequences for employees, to prevent a decrease in the level of social and legal protection of employees. The presence of real guarantees, on the one hand, contributes to the quality and effective performance of their employment function, on the other – their availability ensures the appropriate level of legality and compliance with current regulations by the parties to the employment relationship.
Innovative function of state governance
Authors: Petkevich Alexandra
Published: October 2020

Problem setting. At the current stage of global economic development, innovations play a significant role not only at the industries level but also at the state level of national economies. Innovations make companies and countries significantly more competitive at the global market at the same time increasing local economies’ status. Analysis of recent researches and publications. In order to identify functions of state governance theoretical papers of numerous authors were carefully studied. Innovation function was not stated in the studied works. The provisions on the functions of public administration are highlighted in the works of N.I. Glazunova, R.V. Goloshchapova, A.N. Kramnik, E.K. Borisova, L.V. Smorgunova, Y.A. Tikhomirov. Nevertheless, some issues of the posed problem still need to be covered.
Target of research. With the purpose of deep study and further development of innovation activities in the country it was necessary to identify the new function of state governance – innovation function.
Article’s main body. Different classification of state governance functions have been analyzed and conclusions and assumptions were made about the new innovation function that was not named before. Because of the significant role of the state in influencing innovation processes, coordinating activities of all interested parties in order to obtain an innovative product it is important to underline the new role and to pay it additional attention in further study of state governance.
Conclusions and prospects for the development. The new innovation function has to be defined in the state governance theoretical study. The goal of state influence on innovation processes should be provision of the most optimal, favorable conditions for the most effective interaction of participants in the innovation process with each other. Thus, we consider it appropriate to create a separate institution for the development of innovative function in the country.
Numerical Study of Heat Transfer Characteristics of Laminar Nanofluids Flow in Oblique Finned Microchannel Heat Sink: Effects of Different Base Fluids and Volume Fraction of Nanoparticles
Authors: Ji Ying Choong , Kok Hwa Yu , Abdullah Mohd Zulkifly
Published: October 2020

This paper demonstrates a numerical study of heat transfer characteristics of laminar flow in oblique finned microchannel heat sink using nanofluid with nanoparticles added to various base fluids including water, ethylene glycol and turbine oil as coolant fluid. The width of the primary channel was 0.5 mm and the secondary channel was less than 0.15 mm in the oblique finned microchannel heat sink with an aspect ratio of 3. ANSYS Fluent was employed to model the flow in the geometry of microchannel. Single phase model and constant heat flux boundary condition were used in this numerical study. The modeling was validated by comparing the published data for conventional and enhanced microchannel heat sink. The base fluid acted as a comparison baseline to the nanofluid with volume fraction of 1.0% and 4.0%. Besides, the study was carried out in laminar flow regime, whereby the Reynold number ranged between 320 to 700. It was found that turbine oil based nanofluid had the highest Nusselt number among all fluids, followed by ethylene glycol and water to be the least. However, the heat transfer coefficient among all fluids were contrary to the Nusselt number where water achieved the highest heat transfer coefficient. The addition of nanoparticles increased the heat transfer coefficient of all fluids but it did not enhance their Nusselt number except water.

The nonzero tangential slip velocity at the permeable boundary is considered. A numerical solution is derived for the governing nonlinear boundary value problem using a novel Keller box scheme. The effect of suction Reynold number , Hartman number and slip coefficient on derived quantities such as velocity filed and skin friction at the boundaries are analyzed. The physical significance of the flow parameters is also discussed.
The Role of Hematological Parameters in the Etiology of Missed Abortion
Authors: GÜRBÜZ Tuğba , TANRIDAN OKÇU Nefise
Published: October 2020

Aim: To compare mean platelet volume (MPV) values and platelet counts of normal pregnancies and patients with missed abortions to determine whether hematological parameters such as MPV and platelet counts (PLT) can predict unsuccessful pregnancy particularly missed abortion.

Material and Methods: This retrospective case-control study investigated the hematological parameters of patients diagnosed with missed abortion and the control group. Among 476 cases, 238 participants with missed abortion were included in the study group and 238 healthy pregnant women were included in the control group. The mean age of the missed abortion group was 33.50 and the mean age of the control group was 32.

Result: Age showed a significant difference between the two groups (p = 0.01). Gestational age was higher in the missed abortion group than that in the control group (p < 0.001). Significant differences in gravida (p < 0.001) and parity (p = 0.002) were observed. Smoking was higher in the missed abortion group than that in the control group (p < 0.001). RDW-SD (p < 0.001) and hematocrit (p = 0.032) showed significant differences between groups. There was no significant correlation between MPV (p = 0.155; OR = 1.097; CI = 0.966_1.247), PDW (p = 0.695; OR = 0.991; CI = 0.947_1.037), PCT (P = 0.468) and missed abortion.

Conclusion: Hematological parameters such as MPV may not be used as a screening or diagnostic test for unsuccessful pregnancies particularly missed abortion as shown in the current study.
The Great Inequality and the Dynamical Disintegration of the Outer Solar System
Authors: Zink Jon K. , Batygin Konstantin , Adams Fred C.
Published: October 2020

Using an ensemble of N-body simulations, this paper considers the fate of the outer gas giants (Jupiter, Saturn, Uranus, and Neptune) after the Sun leaves the main sequence and completes its stellar evolution. Due to solar mass loss—which is expected to remove roughly half of the star’s mass—the orbits of the giant planets expand. This adiabatic process maintains the orbital period ratios, but the mutual interactions between planets and the width of mean-motion resonances (MMR) increase, leading to the capture of Jupiter and Saturn into a stable 5:2 resonant configuration. The expanded orbits, coupled with the large-amplitude librations of the critical MMR angle, make the system more susceptible to perturbations from stellar flyby interactions. Accordingly, within about 30 Gyr, stellar encounters perturb the planets onto the chaotic subdomain of the 5:2 resonance, triggering a large-scale instability, which culminates in the ejections of all but one planet over the subsequent ∼10 Gyr. After an additional ∼50 Gyr, a close stellar encounter (with a perihelion distance less than ∼200 au) liberates the final planet. Through this sequence of events, the characteristic timescale over which the solar system will be completely dissolved is roughly 100 Gyr. Our analysis thus indicates that the expected dynamical lifetime of the solar system is much longer than the current age of the universe, but is significantly shorter than previous estimates.
The Energetic Thermonuclear Bursts in SAX J1712.6–3739
Authors: Lin Jie , Yu Wenfei
Published: October 2020

The neutron star low-mass X-ray binary SAX J1712.6–3739 is known for its long and hard thermonuclear X-ray bursts from previous observations. Its thermonuclear bursts are so distinct as they can last for tens of minutes, as seen with Swift/BAT (E > 15 keV). To explore the origin of these extreme bursts and the nature of SAX J1712.6–3739, we analyzed the observations of all four bursts that were captured by Swift/BAT and derived the peak flux and the fluence of these bursts from joint studies with Swift/XRT and Swift/BAT. The derived bolometric peak fluxes observed by Swift set the distance of SAX J1712.6–3739 to be 4.6–5.6 kpc, while the derived absolute magnitude and average accretion rate agree with its ultracompact nature. Our measurements of the effective duration of these bursts conclude that the 2010 burst corresponds to a normal X-ray burst, the 2011 burst is consistent with an intermediate-duration burst, while the 2014 and the 2018 bursts are more energetic than common intermediate-duration bursts but less energetic than those known superbursts. We estimated that the average mass accretion rate of SAX J1712.6–3739 was about only 0.4%–0.7% 

. Current theory predicts no carbon production in the bursters under such low accretion rate. If true, the 2014 and 2018 bursts are then deep helium bursts instead of carbon bursts. The thermonuclear bursts of SAX J1712.6–3739 have shown a very wide range of durations. The ignition model predicts that the diverse burst durations are induced by variable accretion rates, but current results provide only weak support to this inference.

In previous work, we developed a deep neural network classifier that only relies on phase-space information to obtain a catalog of accreted stars based on the second data release of Gaia (DR2). In this paper, we apply two clustering algorithms to identify velocity substructure within this catalog. We focus on the subset of stars with line-of-sight velocity measurements that fall in the range of Galactocentric radii

and vertical distances

. Known structures such as Gaia Enceladus and the Helmi stream are identified. The largest previously unknown structure, Nyx, is a vast stream consisting of at least 200 stars in the region of interest. This study displays the power of the machine-learning approach by not only successfully identifying known features but also discovering new kinematic structures that may shed light on the merger history of the Milky Way.

We present cosmological (30−400 Mpc) distributions of neutral hydrogen (H i) in the intergalactic medium (IGM) traced by Lyα emitters (LAEs) and QSOs at z = 2.1–2.5, selected with the data of the ongoing Hobby–Eberly Telescope Dark Energy Experiment (HETDEX) and the eBOSS survey. Motivated by a previous study of Mukae et al., we investigate spatial correlations of LAEs and QSOs with H i tomography maps reconstructed from H i Lyα forest absorption in the spectra of background galaxies and QSOs obtained by the CLAMATO survey and this study, respectively. In the cosmological volume far from QSOs, we find that LAEs reside in regions of strong H i absorption, i.e., H i rich, which is consistent with results of previous galaxy−background QSO pair studies. Moreover, there is an anisotropy in the H i distribution plot of transverse and line-of-sight distances; on average the H i absorption peak is blueshifted by ∼200 km s−1 from the LAE Lyα redshift, reproducing the known average velocity offset between the Lyα emission redshift and the galaxy systemic redshift. We have identified a ∼40 Mpc scale volume of H i underdensity that is a candidate for a giant H ii bubble, where six QSOs and an LAE overdensity exist at

. The coincidence of the QSO and LAE overdensities with the H i underdensity indicates that the ionizing photon radiation of the QSOs has created a highly ionized volume of multiple proximity zones in a matter overdensity. Our results suggest an evolutionary picture where H i gas in an overdensity of galaxies becomes highly photoionized when QSOs emerge in the galaxies.

The meteoroid input function (MIF) describes the seasonal, diurnal and planetographic distribution of incoming meteoroids onto an atmosphere and/or surface of a solar system body. Utilizing state-of-the-art dynamical models of the main populations of meteoroids, we present a comparative study of the MIF on the atmospheres of Venus, Earth and Mars. Our modeling results show that, although a planet's axial tilt and orbital eccentricity introduce measurable important variability of the overall MIF, excursions from the ecliptic plane due to orbital inclination are responsible for the largest differences, producing variations of up to 40% with respect to the mean value in the overall mass fluxes of Venus and Mars. This is particularly true for meteoroid populations concentrated around the ecliptic plane, which are believed to be the dominant source of organics and metals on the atmospheres of these planets.

Published: October 2020

412 species-group names (including 11 replacement names), and 14 genus-group names of the Alycaeidae have been introduced to date. Type materials of 85% (336) of the known species and subspecies were examined, a further 5% (19) of the taxa were studied using available non-type material, and for another 6% (22) the original descriptions were sufficiently detailed to evaluate their taxonomic status. Only 3% of the taxa (12) could not be examined. Special attention was paid to the sculpture of the embryonic whorls and the sutural tube-microtunnel system in order to provide a novel classification for this group.

In this study 363 taxa (320 species or 43 subspecies) are accepted within the family Alycaeidae. Of these, 22 have been described by the lead author and his coauthors in previous publications. In addition, there are 18 species that were formerly classified in Cycloryx and now belong to Pincerna due to its synonymy with Cycloryx. Among the remaining 323 species, 209 (65%) are transferred here to another genus, whilst 114 (35%) have remained in their original genus.

Seven genera are accepted. While some questions (e.g., the distinction between Pincerna and Alycaeus) remained unanswered, this revision made three main achievements: (1) The Dicharax species were identified based on the absence of spiral striation on the entire shell; (2) the Metalycaeus species were identified based on the spiral striation of the protoconch; (3) and Stomacosmethis was separated from Alycaeus based on the extremely short sutural tube.

Five nominal species are being synonymised with other species, and eight species are now treated as subspecies. The following replacement names are proposed: Dioryx urnula niosiensis Páll-Gergely, nom. nov. for Alycaeus urnula var. daflaensis Godwin-Austen, 1914; Dioryx urnula rotundus Páll-Gergely, nom. nov. for Alycaeus urnula var. globosus Godwin-Austen, 1914; Pincerna crenilabris juttingae Páll-Gergely, nom. nov. for Alycaeus crenilabris laevis van Benthem Jutting, 1959; Pincerna crenilabris korintjiensis Páll-Gergely, nom. nov. for Alycaeus crenilabris latecostatus van Benthem Jutting, 1959; Dicharax conicus jatingaensis Páll-Gergely, nom. nov. for Alycaeus conicus var. nanus Godwin-Austen, 1914; Metalycaeus godwinausteni Páll-Gergely, nom. nov. for Alycaeus neglectus Godwin-Austen, 1914; and finally Metalycaeus suhajdai Páll-Gergely, nom. nov. for Alycaeus varius Godwin-Austen, 1914.
A Summer Professional Immersion in Nursing Program for Underrepresented Minority Undergraduate Students
Authors: Johnson Rolanda L. , Steed Julia , Parker Shaunna , Schorn Mavis N.
Published: October 2020

Background:

By 2044, more than 50% of the U.S. population will consist of ethnic/racial minorities. To facilitate optimal health, the projected nursing workforce should mirror this statistic. This pilot study examined the effects of a Summer Professional Immersion in Nursing Program (SPIN) on confidence in career decision making of under-represented minority undergraduate students. The 4-week program exposed participants to various nursing experiences.

Method:

The Career Decision Self-Efficacy Scale was administered pre- and post-SPIN to measure level of confidence in career decision making.

Results:

The sample included eight women, with an average age of 19.63 years (
SD
= 0.52). Comparative analysis was performed using a reliable change index. The pre- to post-SPIN change was 0.38, indicating a meaningful significant increase in confidence.

Conclusion:

SPIN is an example for nursing programs interested in attracting undergraduate underrepresented minority students. The program positively influenced self-efficacy toward career selection and may positively influence enrollment of underrepresented nurses in the future.

Culture, the Stigma of Mental Illness, and Young People
Authors: Molloy Luke , Beckett Paul , Chidarikire Shep , Merrick Tammy Tran , Guha Monica , Patton Declan
Published: October 2020

Culture is a crucial factor in understanding variations in stigma experiences among young people (age ≤25 years). Cultural beliefs influence the range of social responses that mental health issues elicit, including forms of treatment and role expectations of carers. The current article explores the influence that stigma and culture can have on young people with mental illness. It highlights that it is impossible for nurses to be cognizant of all belief systems related to mental illness. Hence, cultural safety is an approach that can facilitate engagement with the nuances of a young person's culture and provide the foundations of appropriate care. [

Mindfulness-Based Stress Reduction for Stress, Anxiety, and Psychological Well-Being: Effects in a Republic of Korea Navy Fleet Crew
Authors: Kang Hyekyung , Seo Jeong-bok , Hwang In-Young
Published: October 2020

The purpose of the current study was to investigate the effects of a mindfulness-based stress reduction (MBSR) program on perceived stress, depression, anxiety, and psychological well-being of a Republic of Korea (ROK) Navy fleet crew. A quasi-experimental study with a non-equivalent control group pretest/post-test design was used. Participants were randomized to an experimental group (
n
= 18) and control group (
n
= 21). The experimental group received MBSR for 90 minutes per week for eight sessions. Data were analyzed using descriptive statistics and Shapiro-Wilk, chi-square, Mann-Whitney U, and
t
tests. Results showed significant decreases in perceived stress (
t
= −8.24,
p
= 0.015) and anxiety (
t
= −0.25,
p
= 0.041) and improved psychological well-being (
t
= 2.58,
p
= 0.023) in the experimental group compared to the control group. No differences were found for depression between groups. These findings indicate that MBSR was effective in addressing perceived stress, anxiety, and psychological well-being of a ROK Navy fleet crew. This study suggests MBSR can be expanded to other populations at high risk for stress and anxiety. [

Published: October 2020

Esse artigo aborda sobre a relação entre traços de personalidade, atitudes e desempenho do vendedor. Propõe-se que orientação para locomoção e empatia cognitiva são traços de personalidade do vendedor e conhecimento da necessidade do cliente (CNK) e venda adaptativa são comportamentos atitudinais resultantes desses traços. Ademais, propõe-se que os traços de personalidade e atitudes abordados nesse estudo impactam de forma positiva no desempenho do vendedor. Um levantamento foi realizado com 129 vendedores do varejo de materiais para confecções e modelagem de equações estruturais baseada em covariância (CB-SEM) foi realizada. Os resultados indicam que orientação para locomoção tem relação positiva com CNK enquanto empatia cognitiva apresenta uma relação positiva com venda adaptativa. Além do mais, os resultados indicam que o desempenho em vendas aumenta quando vendedores possuem altos níveis de orientação para locomoção, empatia cognitiva, CNK e venda adaptativa.
