Background: Approximately 20% of people diagnosed with cancer in the U.S. travel from rural areas to urban cancer centers for treatment. Rural cancer patients face unique challenges which may contribute to greater psychosocial distress when compared to urban-dwelling patients. While up to half of all cancer patients screen positive for psychosocial distress, only 25-44% of distressed patients utilize psychosocial care. Patients from rural areas may face greater barriers to utilization of psychosocial care compared to patients from urban areas. To date, few studies have focused on these concerns. Methods: Three-years of data were collected from newly diagnosed patients screened between 2015 and 2017, including the Patient Health Questionnaire-2 and the NCCN Distress Thermometer (n = 4,865). Adjusted multi-variable logistic regression, chi-square, and negative binomial regression were used to assess relationships among psychosocial outcomes and care utilization, rurality, and distance to treatment in driving miles, controlling for socio-demographic and clinical covariates. Distance to treatment based on driving miles computed in ArcGIS v10.5. Stata v15 was used for all statistical analyses, significance set at ≤.05. Results: Higher odds of depressive symptoms were detected among people living in rural areas compared to urban areas. The odds of psychosocial distress were higher in patients from rural areas and further distances from treatment compared to local distance. Patients from rural areas had lower odds of psychosocial care utilization compared to patients in urban areas. Distance to treatment had independent effects, over and above rurality, for lower odds of psychosocial care utilization. Conclusions: Distance to treatment and rurality appear to be risk factors with independent effects on depressive symptoms and psychosocial distress and appear to be associated with lower odds of psychosocial care use among cancer patients with self-reported distress when compared to patients from urban and local areas. Findings support improved detection of and response to patient reported psychosocial outcomes, and further research designed to better understand the mechanisms underlying the reported associations.

Background: Pain is one of the most common symptoms in cancer patients and often has a negative impact on patients’ functional status and quality of life. Cognitive dysfunction can impact the assessment and treatment of pain. Taking analgesics may worsen the cognitive dysfunction. The study of the prevalence of cognitive dysfunction and the association with analgesics in the CP patients is rare in China. This study aimed to investigate the prevalence of cognitive dysfunction in Chinese CP patients and analyze the related factors. Methods: A total of 220 Chinese CP patients in 9 first-grade hospitals received the following assessment: the functional assessment of cancer therapy-cognitive function (FACT-Cog) and numerical rating scale (NRS), Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7). ANOVA and multiple linear regression analysis were performed to explore the related factors. Results: A total of 220 Chinese CP patients received the assessment: The overall incidence of cognitive dysfunction in CP patients was 33.64%, with an average cognitive function score 105.93±21.39. The total cognitive function score and each dimension were negatively correlated with the pain, depression, and anxiety levels. The analgesics did not affect the cognitive function of CP patients. Sleep and smoking history were two key factors influencing the cognitive function. Conclusions: An effective management of pain, depression, anxiety, sleep, and smoking are recommended to protect the cognitive function of patients under CP stress. It is safe and reliable to regularly use the analgesics for CP patients. Clinical trial information: NCT03641820.

Background: Traditionally, palliative care in most hospitals is delivered through consult-based services i.e relying on the primary physician to initiate a referral to a palliative care specialist. Supportive and Palliative Care Review Kit (SPARK) is a newly developed integrated model of care that involves a Palliative Consultant and an Advanced Practice Nurse (APN) co-rounding with the oncologist to provide bedside palliative care advice alongside the oncology team. Methods: To evaluate the effect of this new model on staff outcomes of teamwork and job satisfaction, a survey was conducted in March 2018 before the new SPARK model was started and 1 year later in March 2019. The survey was adapted from the Primary Care Team Dynamics Survey and Physician Worklife Survey, with higher scores indicating better outcomes. Categorical variables were analysed using chi-square test and continuous variables were analysed using student’s t-test. Results: Before the new SPARK model was started in March 2018, email invitations were sent to 89 oncology and palliative care physicians. Fifty five complete responses was received (61.8% response rate). A year after the new SPARK model was started, email invitations were sent to 23 oncology and palliative care physicians who had experienced the new model of care, of which 8 complete responses were returned (34% response rate). There was no significant differences in demographics between the two time points and in the total and domain scores between before and after SPARK. In the ‘personal time’ domain of the physician worklife survey, scores were better after SPARK (73.8± 6.68) compared to before SPARK (68.4 ± 8.70). This may be due to increased independence experienced by the APN co-rounding with the oncology team. The flexibility in team-rounding creates more personal time allowing the APN to be involved in other non-clinical tasks. Conclusions: While there were no statistically significant differences in the overall work experience, team dynamics and job satisfaction one year after the SPARK model, this may be due to small sample size.

Authors: Corcoran Stacie , Kenny Sheila
Published: November 2019

Background: The number of cancer survivors in the United States is expected to approach 22 million by the year 2029. With an annual Survivorship Program visit volume exceeding 16,000, this comprehensive cancer center developed an innovative approach to delivering survivorship care to meet the growing demand for comprehensive follow up care. Institutional space, patient convenience and visit compliance are also factors in considering alternatives to traditional ‘brick and mortar’ visits. Methods: Patients are seen in our Autologous Bone Marrow Transplant (BMT) Survivorship Clinic at 6, 12- and 24-months post-transplant. A pilot was developed targeting patients scheduled for a 6-month visit, where patients are often struggling with treatment sequelae, managing other medical appointments, and returning to work and life after transplant. Patients were offered a telemedicine visit instead of an in-person clinic visit with the survivorship advanced practice provider (APP). The Survivorship APP and administrative staff were trained on the use of monitors and technologic means to connect patient to provider. Eligible patients had to have an institutional portal account and speak English. They were contacted by phone to assess interest, and if they agreed, instructions were provided via secure institutional portal reviewing device and connectivity requirements. Results: The telemedicine visit components included: review of home medication list, interval history and review of systems, screen for late treatment effects, lab result review, treatment summary and care plan review including risk of secondary cancer and screening recommendations, health promotion counseling, primary care physician recommendations and immunization status. Of 26 visits scheduled, 22 were successfully completed. Challenges to completing the visit will be described and include poor connectivity and patient location at the time of the scheduled visit. Conclusions: Despite some minor challenges, patients described good satisfaction with telemedicine citing visit comprehensiveness and convenience. As a result of the successful pilot, telemedicine visits are being expanded to include survivorship patients who are 24 months post BMT.

Background: Pain is frequently reported by individuals with cancer. While the adverse effects of pain on quality of life are well-established, it is unknown if pain is associated with patients’ concerns about employment and cancer costs. Methods: We used data from the Medical Expenditure Panel Survey (MEPS) 2016 Experiences with Cancer Supplement including cancer diagnosis, pain level over the past 7 days, employment changes, and cost concerns. Respondents diagnosed with cancer at age > 18 (excluding non-melanoma skin cancer) with non-missing pain information were included. Sampling weights were used in analysis to provide nationally representative estimates. Results: Among 875 eligible respondents with cancer (weighted total of 1.3 million individuals), pain was reported by 57% (severe pain by 12%). The likelihood of pain was significantly associated with age, gender, race/ethnicity, education, cancer site, insurance, and time since treatment. Controlling for these factors, individuals reporting pain were significantly more likely to take time off from work (odds ratio [OR] 1.76); change to a less demanding or part time job (OR 1.91); not pursue promotions (OR 1.39); retire early (OR 3.06); and feel less productive (OR 2.35). Individuals with pain were significantly more likely to have uncovered medical expenses (OR 1.28); be in debt (OR 2.68); and be unable to cover medical bills (OR 1.46). These individuals were significantly more likely to worry about paying medical bills (OR 1.94); to delay medical treatment (OR 4.30), follow-up care (OR 2.20), and mental health care (OR 4.11); and were less likely to receive necessary medical care (OR 0.50). Despite these, concerns, they were significantly less likely to discuss out-of-pocket costs for cancer care (OR 0.86) or cancer treatments (OR 0.96) with a healthcare provider. Conclusions: Cancer pain is associated with increased cost and employment concerns but with a lower likelihood of discussing costs with healthcare provider. Interventions are needed to address financial hardship among this high-risk population.

Smokers are at increased risk for surgical complications. Despite the known benefits of smoking cessation, many perioperative health care providers do not routinely provide smoking cessation interventions. The variation in delivery of perioperative smoking cessation interventions may be due to limited high-level evidence for whether smoking cessation interventions used in the general population are effective and feasible in the surgical population, as well as the challenges and barriers to implementation of interventions. Yet smoking is a potentially modifiable risk factor for improving short- and long-term patient outcomes. The purpose of the Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement on Perioperative Smoking Cessation is to present recommendations based on current scientific evidence in surgical patients. These statements address questions regarding the timing and intensity of interventions, roles of perioperative health care providers, and behavioral and pharmacological interventions. Barriers and strategies to overcome challenges surrounding implementation of interventions and future areas of research are identified. These statements are based on the current state of knowledge and its interpretation by a multidisciplinary group of experts at the time of publication.

Introduction

There is a paucity of information on the clustering of cardiometabolic risk factors in young adults and how this clustering may vary based on whether or not they perform sufficient levels of physical activity.

Methods

We analyzed baseline data from 346 young adults (23.3 ± 4.4 yr) participating in the Healthy Body Healthy U clinical trial from 2015 to 2018. Cardiometabolic risk factors were measured according to standard procedures and moderate- to vigorous-intensity physical activity (MVPA) was determined by accelerometry. A cardiometabolic clustering score (ranging from 0 to 5) was created from five biomarkers according to whether or not a standard clinical risk cut point was exceeded (0, no; 1, yes): abdominal circumference (>102 cm (men) or >88 cm (women)), hemoglobin A1c (≥5.7%), HDL cholesterol (<40 mg·dL−1 (men) or <50 mg·dL−1 (women)), systolic blood pressure (≥130 mm Hg), and diastolic blood pressure (≥85 mm Hg). Cardiometabolic dysregulation (CD) was defined as a cardiometabolic clustering score ≥3. Multiple logistic regression determined the independent association between level of MVPA and CD, while adjusting for sex, race/ethnicity, sedentary time, and smoking.

Results

The prevalence of CD was 18% (22% in men, 17% in women). We observed a nonlinear graded association between MVPA and CD. Participants performing 150–300 min·wk−1 of MVPA significantly lowered their odds of CD by 66% (odds ratio, 0.34; 95% confidence interval, 0.16–0.75), whereas those exceeding 300 min·wk−1 lowered their odds by 61% (odds ratio, 0.39; 95% confidence interval, 0.18–0.86) compared with those performing <150 min·wk−1, independent of obesity and the other covariables.

Conclusion

Recommended levels of moderate-intensity physical activity is significantly associated with lower odds of CD and thus may prevent or diminish the need for expensive pharmaceutical treatment over the remainder of the life-span.
Interactions between SAM and the 5′ UTR mRNA of the sam1 gene regulate translation in S. pombe
Authors: Zhang Xuhui , Sun Wenxia , Chen Dongrong , Murchie Alastair I.H.
Published: November 2019

The 5′ untranslated region (5′ UTR) of eukaryotic mRNA plays an important role in translation. Here we report the function of the 5′ UTR mRNA of S-adenosylmethionine synthetase (sam1) in translational modulation in the presence of SAM in fission yeast Schizosaccharomyces pombe. Reporter assays, binding and chemical probing experiments, and mutational analysis show that the 5′ UTR mRNA of sam1 binds to SAM to effect translation. Translational modulation is dependent on a tertiary structure transition in the RNA upon SAM binding. The characterization of such an RNA that is directly associated with an essential metabolic process in eukaryotes provides additional evidence that ligand binding by RNAs plays an important role in eukaryotic gene regulation.
Preprints and Scholarly Communication: An Exploratory Qualitative Study of Adoption, Practices, Drivers and Barriers
Authors: Chiarelli Andrea , Johnson Rob , Pinfield Stephen , Richens Emma
Published: November 2019

Background: Since 2013, there has been a dramatic increase in the number of preprint servers. Little is known about the position of researchers, funders, research performing organisations and other stakeholders with respect to this fast-paced landscape. In this article, we explore the perceived benefits and challenges of preprint posting, alongside issues including infrastructure and financial sustainability. We also discuss the definition of a ‘preprint’ in different communities, and the impact this has on uptake.

Methods: This study is based on 38 semi-structured interviews of key stakeholders, based on a purposive heterogeneous sampling approach and undertaken between October 2018 and January 2019. Interviewees were primarily drawn from biology, chemistry and psychology, where use of preprints is growing. Interviews were recorded, transcribed and subjected to thematic analysis to identify trends. Interview questions were designed based on Innovation Diffusion Theory, which was also used to interpret our results.

Results: Participants were conscious of the rising prominence of preprints and cited early and fast dissemination as their most appealing feature. Preprints were also considered to enable broader access to scientific literature and increased opportunities for informal commenting. The main concerns related to the lack of quality assurance and the ‘Ingelfinger rule’. We identified trust as an essential factor in preprint posting, and highlight the enabling role of Twitter in showcasing preprints.

Conclusions: The preprints landscape is evolving fast, and disciplinary communities are at different stages in the innovation diffusion process. The landscape is characterised by experimentation, which leads to the conclusion that a one-size-fits-all approach to preprints is not feasible. Cooperation and active engagement between the stakeholders involved will play an important role going forward. We share questions for the further development of the preprints landscape, with the most important being whether preprint posting will develop as a publisher- or researcher-centric practice.
Understanding diverse TRPV1 signaling – an update
Authors: Andresen Michael
Published: November 2019

The transient receptor potential vanilloid 1 (TRPV1) is densely expressed in spinal sensory neurons as well as in cranial sensory neurons, including their central terminal endings. Recent work in the less familiar cranial sensory neurons, despite their many similarities with spinal sensory neurons, suggest that TRPV1 acts as a calcium channel to release a discrete population of synaptic vesicles. The modular and independent regulation of release offers new questions about nanodomain organization of release and selective actions of G protein–coupled receptors.

STratifying Resilience and Depression Longitudinally (STRADL) is a population-based study built on the Generation Scotland: Scottish Family Health Study (GS:SFHS) resource. The aim of STRADL is to subtype major depressive disorder (MDD) on the basis of its aetiology, using detailed clinical, cognitive, and brain imaging assessments. The GS:SFHS provides an important opportunity to study complex gene-environment interactions, incorporating linkage to existing datasets and inclusion of early-life variables for two longitudinal birth cohorts. Specifically, data collection in STRADL included: socio-economic and lifestyle variables; physical measures; questionnaire data that assesses resilience, early-life adversity, personality, psychological health, and lifetime history of mood disorder; laboratory samples; cognitive tests; and brain magnetic resonance imaging. Some of the questionnaire and cognitive data were first assessed at the GS:SFHS baseline assessment between 2006-2011, thus providing longitudinal measures of depression and resilience. Similarly, routine NHS data and early-life variables are linked to STRADL data, further providing opportunities for longitudinal analysis. Recruitment has been completed and we consented and tested 1,188 participants.

Artykuł jest analizą wybranych aspektów czynów popełnionych przez kobiety i polegających na zgwałceniu ze szczególnym okrucieństwem. W pierwszej części zaprezentowano krótki rys historyczny w podejściu do przestępczości kobiet. W drugiej autorka przedstawia wyniki badań własnych dotyczących zgwałceń ze szczególnym okrucieństwem dokonanych przez kobiety. Badanie przeprowadzone zostało w oparciu o materiał empiryczny pochodzący ze spraw karnych, w których podstawą skazania był artykuł 197§4 k.k., a sprawcami bądź współsprawcami czynów były kobiety. Ze względu na szczególny charakter przestępstwa materiał badawczy stanowiły akta spraw sądowych zakończonych prawomocnym wyrokiem. Analizom poddano sprawy karne zakończone prawomocnym wyrokiem w latach 2005-2012. W analizowanych sprawach kobiety pełniły aktywną, agresywną bardzo często dominującą rolę zarówno w planowaniu czynu jak i w jego realizacji. Wszystkie czyny dokonane zostały wspólnie z mężczyznami, a kobiety w trakcie ich popełniania były pod wpływem alkoholu. Prezentowane wyniki badania ukazują kobietę sprawczynię zgwałcenia w nieco innym świetle niż dotychczas prezentowane badania, warto podkreślić jednak że wyniki analiz należałoby pogłębić, poszerzyć o dodatkowe przypadki nie tylko zgwałceń ze szczególnym okrucieństwem ale również innych przestępstw.

FACTORS THAT AFFECTING THE TOXICITY OF POLLUTANTS TO AQUATIC ORGANISMS. There are a large number of pollutants in aquatic environment with various characteristics and factors that can modify and affect the toxicity of pollutants in this environment. The major factors affecting pollutant toxicity include physicochemical properties of pollutants, mode of exposure, time, environmental factors, and biological factors. Moreover, organisms in an aquatic ecosystem are seldom exposed to only single pollutant, and most cases the stress of pollution on aquatic ecosystems is related to the interaction and combined effects of many chemicals. The combined effects may be synergistic or antagonistic, depending on the pollutants and the physiological condition of the organism involved.

Published: November 2019

Objective: In this study, we sought to determine whether a multi-factor behavioral index predicts mammography screening in US women. Methods: Women aged 50-75 years were enrolled in an intervention study and provided their vegetable intake, physical activity (PA), smoking,
body mass index (BMI), and alcohol intake. Each factor was scored from 0 (least healthy) to 4 (most healthy) then summed to form a multi-factor behavioral index (ranging from 0-20). Self-report and medical records were used to determine mammography screening 6-months post-intervention. Logistic
regression was used to estimate multivariable-adjusted odds ratios (OR) and 95% confidence intervals (CI) for the association with 6-month mammography. Results: The mean score for the multi-factor index was 11.8. An increased index score marginally predicted mammography adherence [OR
= 1.05 (0.99-1.11)], with a stronger association among women receiving a doctor's recommendation for mammography [OR = 1.12 (1.04-1.20)]. Of the independent behavioral factors, high PA [OR = 1.13 (0.99-1.30), p = .075] and low BMI [OR = 1.25 (1.04-1.51), p = .017] were marginal and significant
predictors of mammography, respectively. Conclusion: Women who engaged in a healthier behavioral lifestyle were more likely to utilize mammography screening, especially if they received a physician recommendation. Physicians should encourage mammography screening as part of a healthy
behavioral lifestyle.

This study aims to identify variants of Islamic religiosity in Chinese Muslim life as reflected in the organization of the Indonesian Chinese Islamic Association (Persatuan Islam Tionghoa Indonesia/PITI). This organization has distinctive features about how dialogue between Islam, Chinese ethnicity, implementation of Indonesian Islamic law legislation, and Javanese culture occured. This study uses a symbolic-interpretative anthropology approach. The conclusion of this study includes as the following (1) the organizational system of PITI in Jepara district is driven by indigenous Muslims who are active as administrators of the Nahdlatul Ulama in Jepara district and only two people of Chinese descents are administrators, while others are members; on the other hand, the involvement of "influential people" in the political world in Jepara also supports its existence. As for the organization funding is obtained and managed independently in the management level in Jepara; (2) Islamic characteristics of the PITI Muslim community in Jepara regency include muallaf status, feeling of being a minority but having sufficient economic, secular-materialist tendencies, prominent Chinese culture, and still strong pressure from family circles for Islam; and (3) the dimensions of Chinese socio-culture and the lives of indigenous people are more visible in socio-cultural life than the influence of religious norms.

Published: November 2019

Computational techniques based on ranks of Hankel matrices is used to study the convergence to Arnold tongues. It appears that the process of convergence to the phaselocked mode is far from being trivial. The stable, the unstable and the manifold of nonasymptotic convergence intertwine in the parameter plane of the circle map. Pseudoranks of Hankel matrices carry important physical information about transient processes taking place in discrete nonlinear iterative maps. These pictures in the parameter plane are also beautiful from the aesthetical point of view.

Published: November 2019

The article examines the dependencies of individual sectoral stock price indices of OMX Baltic security market on sectoral indicators of Lithuania economy, using econometric methods. Regression models are constructed using quarterly time series of 2005–2013 years. VAR models obtained in the [3] paper have been extended to verify if the inclusion of sectoral economy indicators improves the ability to provide a higher level of accuracy in estimating the growth of sectoral price index. These indicators significantly improve the predictive power compared with the benchmark VAR model. The short-term forecasts of the investigated models are obtained. Econometric analysis of OMX Baltic security market proves the hypothesis that the set of sectoral regressors may vary considerablydepending on the individual sector’s price indices.

Published: November 2019

We have made a practical consideration of an important case of nonlinear diffusion of impurities in a three-dimensional case through square window in the x, y plane for the production of electronic devices and evaluation of its parameters. The nonlinear diffusion coefficients for diffusion in x, y, z directions are proportional to the concentration of impurities. The three-dimensional nonlinear diffusion equation was transformed using similarity variables. The approximate analytical solution of the transformed equation expressed by Taylor series approximate expansion for three similarity variables about the maximum impurities penetration points in x, y, z axes including the square terms.
Nonlinear diffusivity dependence on dimensions
Authors: Janavičius Arvydas Juozapas , Turskienė Sigita , Žilinskas Kęstutis
Published: November 2019

The nonlinear diffusion equation corresponds to the diffusion processes which can occur with a finite velocity. This statement is not satisfied in Fick’s second law or linear diffusion equation. The processes by which different materials mix in the result of the random Brownian motions of atoms, molecules and ions can be exactly described only with presented nonlinear equation. It was important in practice that theoretically profiles fit with the experimental profiles tail region, but get good coincidence between diffusion experiments and the classical solutions is impossible. By using obtained theoretical solutions for two and three-dimensional cases we can provide more exact modeling of all the stages of a planar transistor formation.
Algebraic and spectral analysis of local magnetic field intensity

Published: November 2019

One of the kind in Europe magnetometer is situated in central Lithuania and registers local magnetic field intensity. The sensitivity of the device is of pT (pico teslas) order. Magnetic field intensity is a real world sequence and as a result does not have a rank. Nevertheless, H-rank based techniques enable to analyse the data as algebraic sequences. The work also pays a considerable amount of attention to the spectral distribution of the signal. A specialized software is being developed due to the amount of the data and computational time costs for problems investigated.

Berdasarkan hasil identifikasi spesies yang dilakukan, ikan – ikan tersebut berasal dari lima family ikan yaitu Cyprinidae, Loricariidae, Palaemonidae, Zenarchopteridae dan Penaeidae. Selain itu, diperoleh sejumlah tujuh spesies ikan termasuk satu ikan asing yaitu ikan sapu-sapu (Pterygoplichthys pardalis). Hasil analisa menunjukkan bahwa indek keanekaragaman, keseragaman dan dominasi pada seluruh titik sampling masih dalam kondisi normal. Namun demikian, dengan ditemukannya ikan sapu-sapu (P. pardalis) pada sistem Sungai Cibanten mungkin akan memiliki dampak negatif terhadap ekologi sungai. Penelitian lebih lanjut dibutuhkan untuk mengevaluasi lebih lanjut keberadaan ikan sapu-sapu dan ikan asing lainnya yang memiliki potensi bahaya terhadap ekologi Sungai Cibanten.

Osteoarthritis is a prevalent and costly condition. Knowledge of the quality of care being offered to people with hip and knee osteoarthritis in New Zealand is limited. The aim of this study was to investigate the quality of care being offered to people with hip and knee osteoarthritis in New Zealand, and to investigate common pathways of care. The OsteoArthritis Quality Indicator (osteoarthritis) questionnaire was administered to adults with hip and/or knee osteoarthritis, and participants were also asked to list the healthcare professionals they had consulted. Descriptive statistics with 95% confidence intervals were calculated. The study included 106 participants (87% female, n = 92; 94% European, n = 100). The mean OsteoArthritis Quality Indicator achievement rate was 50.2% (95% confidence intervals 41.0–59.7%). OsteoArthritis Quality Indicator achievement rates were lowest for weight reduction referral (8.6%; 3.7–17.8%) and daily activity aids assessment (18.5%; 10.2–31.0%), and highest for physical activity education (80.8%; 72.1–87.3%) and offering of paracetamol (80.0%; 71.3–86.6%). Following consultation with a general practitioner, 22% (n = 24) consulted orthopaedic surgeons while 15% (n = 17) consulted physiotherapists. The results suggest that implementation of evidence informed conservative treatments for osteoarthritis in primary care is suboptimal, although evidence from a larger representative sample is needed.

Published: November 2019

This article looked for key elements on how to implement a smart city or a smart territory from a technological perspective in Colombia. The study found that the achievement of smart territory has two major components. The first is political commitment at the highest level, which serves as the sponsor and facilitator of the process; coupled with the definition of public policy on intelligent territories, in a framework that brings together the Development Plans, creating economic, technological and social welfare synergies. The second is the social, technical and financial component, which consults regional realities to model and execute intelligent territory in a participatory manner.

This study analyzes the perceptions of the owners and/or managers of family businesses in the Ñuble territory of Chile, according to the dimensions of succession, performance and managerial capacity. Methodologically, hierarchical conglomerate analysis was used, obtaining a Cronbach alpha of 0.789. Three generations stand out: first (47.6%), second (38.1%) and third (14.3%), where the managerial capacity is determinant in the sustainability. There are problems in the succession for lack of planning of the process and the potential successors do not wish to continue with the company given their interests and levels of professionalization. Future performance is related to emotional capital and the degree of innovation.RESUMENEste estudio analiza las percepciones de los dueños y/o gestores de empresas familiares del territorio Ñuble de Chile, según las dimensiones sucesión, desempeño y capacidad gerencial.

This research article aims to establish whether equitable management by managers improves the personal role of their employees thanks to the skills acquired in the work and if this improvement of the personal role could mediate the relationship between equitable management and identification with the company. The method used was a self-reported questionnaire to 19 working groups led by a manager, 398 women and 413 men. Structural equations by partial least squares (SEM-PLS) are applied. Results: the equitable behavior of the managers favors the personal life of the employees although the relationship and its intensity are not high. The models with a mediating variable of work-life enrichment explain the relationship between an equitable management with the identification with the company. Other results and differences between sexes and the gender of the manager are discussed.RESUMENEste artículo de investigación pretende establecer si la gestión equitativa por parte de los gerentes mejora el rol personal de sus empleados gracias a las habilidades adquiridas en el trabajo y si esta mejora del rol personal pudiera mediar la relación entre la gestión equitativa y la identificación con la empresa. El método empleado fue un cuestionario auto-informado a 19 grupos de trabajo dirigidos por un gerente/a, 398 trabajadoras y 413 trabajadores. Se aplican ecuaciones estructurales por mínimos cuadrados parciales (SEM-PLS). Resultados: la conducta equitativa de los gerentes favorece la vida personal de los/las empleados, aunque la relación y su intensidad no son elevados. Los modelos con variable mediadora de enriquecimiento laboral – vida personal explican en mayor medida la relación entre una gestión equitativa con la identificación con la empresa. Se discuten otros resultados y las diferencias entre sexos y el sexo del gerente.RESUMOEste artigo de pesquisa visa estabelecer se a gestão eqüitativamente pelos gerentes melhora o papel pessoal de seus trabalhadores graças às habilidades adquiridas no trabalho e se essa melhoria do papel pessoal poderia mediar a relação entre gestão equitativa e identificação com a empresa.

The purpose of this investigation is to confirm that brands are more influential than the price and the design in the purchase decision making of fashion products. For this, two quasiexperiments were applied to peruvian millennials.It is shown that this segment is loyal to brands, but not to all its products categories, because the price and the design may be more relevant in the purchase of some of these in specific. In this way, it is determined that brand equity or the value of a fashion brand may vary depending on clothing types.RESUMENEl propósito de esta investigación es comprobar que la marca es más influyente que el precio y el diseño en la decisión de compra de productos de moda.
