Generation X versus Millennials communication behaviour on social media when purchasing food versus tourist services

Knowledge and proper understanding of the needs, expectations, desires, demands, values or preferences of Generation X and Millennials is an essential goal of any company. The mission of marketers is increasingly diffi cult because they have to develop a marketing mix able to target effi ciently all customers, invoking satisfaction and loyal behavior. Communication strategy therefore has a special role to play. While Millennials are easier to target, persuade even infl uence through social media, Gen Xers are more conservative, preferring to look for additional information about products and companies themselves, which makes the marketer’s job even more diffi cult. Nowadays, social media plays an increasingly important part in infl uencing consumers and their consumption behavior. Being able to expand beyond geographical borders, social media creates strong links between consumers in different states and social environments. Research conducted among Gen Xers and Millennials shows that whenever they choose food products and tourist services based on recommendations and the information available on social media, their purchasing behavior depends on their own personal desire to become informed, and the characteristics they expect from a piece of information and from the Internet as a general source of information. Given this, companies changed and adapted their communication strategies in order to be more present online. In addition, for those interested, companies create offi cial pages that can represent a strong support for those interested in acquiring information. Quite often, consumers have the possibility to compare goods and services before buying, minimizing the risks attached to these acquisitions. The results reveal that Millennials have stronger affi nity with, and place greater reliance upon online information than Gen Xers. From a managerial perspective, this paper provides retailers with the opportunity to better understand the behavior of customers of different ages, making their targeting more successful.
Effects of IFRS 16 on Key Financial Ratios of Spanish Companies

En este trabajo se lleva a cabo un análisis empírico para estimar el efecto de la nueva norma contable de arrendamientos (NIIF 16) en los estados financieros de las empresas españolas. La literatura previa sobre el impacto de la capitalización de los arrendamientos operativos se ha desarrollado sin considerar la versión final de dicha norma (debido a que aún no se había emitido). En este sentido, nuestras asunciones son más consistentes con la versión final de la norma en aspectos como el plazo del arrendamiento, el tipo de descuento o cómo se valoran el activo y pasivo por arrendamiento. La adopción de la NIIF 16 tendrá un impacto significativo en los estados financieros de las firmas españolas, incluso mayor que el impacto en las empresas europeas en los sectores más afectados y mayor al impacto observado por la literatura anterior. Se espera un importante impacto en balance a consecuencia del incremento en activos y pasivos, dando lugar a un incremento en los ratios de apalancamiento. El ratio de cobertura de intereses muestra un descenso importante. Estos efectos son mayores en empresas de mayor uso relativo del arrendamiento operativo tales como comercio al por menor, hoteles, servicios profesionales y media. Finalmente, al igual que en análisis previos, no encontramos unos resultados consistentes respecto a la rentabilidad. Nuestro estudio puede ayudar a los analistas debido a que mejora la metodología para la estimación del impacto de la capitalización de los arrendamientos.
Patients With Adhesive Small Bowel Obstruction Should Be Primarily Managed by a Surgical Team

Objective: To evaluate the impact of a primary medical versus surgical service on healthcare utilization and outcomes for adhesive small bowel obstruction (SBO) admissions. Summary Background Data: Adhesive-SBO typically requires hospital admission and is associated with high healthcare utilization and costs. Given that most patients are managed nonoperatively, many patients are admitted to medical hospitalists. However, comparisons of outcomes between primary medical and surgical services have been limited to small single-institution studies. Methods: Unscheduled adhesive-SBO admissions in NY State from 2002 to 2013 were identified using the Statewide Planning and Research Cooperative System. Bivariate and mixed-effects regression analyses were performed assessing factors associated with healthcare utilization and outcomes for SBO admissions. Results: Among 107,603 admissions for adhesive-SBO (78% nonoperative, 22% operative), 43% were primarily managed by a medical attending and 57% were managed by a surgical attending. After controlling for patient, physician, and hospital-level factors, management by a medical service was independently associated with longer length of stay [IRR = 1.39, 95% confidence interval (CI) = 1.24, 1.56], greater inpatient costs (IRR = 1.38, 95% = 1.21, 1.57), and a higher rate of 30-day readmission (OR = 1.32, 95% CI = 1.22, 1.42) following nonoperative management. Similarly, of those managed operatively, management by a medicine service was associated with a delay in time to surgical intervention (IRR = 1.84, 95% CI = 1.69, 2.01), extended length of stay (IRR=1.36, 95% CI = 1.25, 1.49), greater inpatient costs (IRR = 1.38, 95% CI = 1.11, 1.71), and higher rates of 30-day mortality (OR = 1.92, 95% CI = 1.50, 2.47) and 30-day readmission (OR = 1.13, 95% CI = 0.97, 1.32). Conclusions: This study suggests that management of patients presenting with adhesive-SBO by a primary medical team is associated with higher healthcare utilization and worse perioperative outcomes. Policies favoring primary management by a surgical service may improve outcomes and reduce costs for patients admitted with adhesive-SBO.
Outcomes of the Distal Metatarsal Dorsiflexion Osteotomy for Advanced Hallux Rigidus

Background: Hallux rigidus can be treated using several different methods and the best treatment option depends on the severity of degenerative changes of the metatarsophalangeal (MTP) joint. However, the ideal operative option for advanced hallux rigidus remains debatable. This prospective study was performed to evaluate the intermediate-term clinical outcomes of distal metatarsal osteotomy used as a joint-preserving method for the treatment of advanced hallux rigidus. Methods: Forty-two cases (39 patients) were followed for more than 3 years after distal metatarsal dorsiflexion osteotomy for advanced hallux rigidus of grade III-IV. Clinical evaluations included the American Orthopaedic Foot & Ankle Society (AOFAS) scores, Foot and Ankle Ability Measure (FAAM) scores, and patient subjective satisfaction scores. Range of motion (ROM) of great toe, complications, reoperation rates, width of the MTP joint space, and times to union were evaluated. Results: Mean AOFAS hallux and mean FAAM scores significantly improved from 56.4 and 61.2 points preoperatively to 87.6 and 88.7 points at final follow-up, respectively (P < .001). Grade III and IV groups had significantly different AOFAS and FAAM scores at final follow-up. Mean dorsiflexion of great toe significantly improved from 14.8° preoperatively to 35.5° at final follow-up (P < .001). Mean patient satisfaction score at final follow-up was 92.8 points. There were 4 cases (9.5%) of subsequent fusion and 2 cases (4.8%) of transfer metatarsalgia. Conclusions: Distal metatarsal dorsiflexion osteotomy using bio-compression screws appears to be an effective operative option for grade III advanced hallux rigidus with viable cartilage on >50% of the first metatarsal articular surface, as it restored joint motion, provided reliable pain relief, and did not require implant removal. However, based on the unsatisfactory clinical results and the high rate of reoperation observed, the authors cannot recommend this operative method for the treatment of end-stage (grade IV) hallux rigidus. Level of Evidence: Level IV, prospective case series.
Adherence to physical activity guidelines and functional fitness of elderly women, using objective measurement.

INTRODUCTION AND OBJECTIVE Physical activity is an important factor in maintaining the health and functional fitness of elderly people. The aim of the study was to determine the number of senior women meeting the physical activity guidelines, and their level of functional fitness in comparison to women who are not sufficiently physically active. MATERIAL AND METHODS The study involved 61 women, aged 60-75. Physical activity was monitored on seven consecutive days of the week, using a triaxial accelerometer ActiGraph GT3X. Results of the assessment of physical activity were verified against the Global Recommendations of Physical Activity for Health. The Senior Fitness Test (Fullerton Test) was used to evaluate functional fitness. RESULTS In the studied group, 36.1% achieved the recommended level of physical activity. All those examined mainly undertook physical activity of low intensity. Vigorous physical activity during the week was noted in only 6 seniors. Women who met the recommendations of physical activity achieved significantly better results in test trials, e.g. Chair Stands, Up and Go, Six Minute Step Test. CONCLUSIONS Adherence to physical activity guidelines was associated with better functional fitness of older women. However, less than half of the examined seniors met the Global Recommendations on Physical Activity for Health.
Adult child survivor syndrome on deprived childhoods of aging Holocaust survivors.

UNLABELLED The present paper aims at understanding the psycho-(patho-)logical status of aging child survivors (CSs) of the Holocaust. BACKGROUND CSs had deprived childhoods, were exposed to massive trauma and losses, then rebuilt their existences. Their post-Holocaust malaise was suppressed and split off from daily life and overt activities, only to reappear, after a delay, in different forms and intensities, further aggravating upon aging. METHOD Following a definition of age, origin, number of living CSs, types of early traumatic impacts, and introductory remarks on what CSs experienced as children and as young adults in the postwar society, the psychosocial research on adult and aging CSs is reviewed. RESULTS The concept of childhood-deprivation and its late sequelae can be substantiated. Definitions of child-survivor complex, CS syndrome and adult child-survivor syndrome are proposed. Non-professional caretakers discerned earlier the existence or extent of the adult CS syndrome Limitations of psychiatric investigation of ACs are the lack of agreed-upon diagnostic criteria.
Strategic leadership: an educational leader imperative

Strategy and strategic leadership have been overlooked largely in leadership literature. The study of strategic leadership is relatively new, although Hofer & Schendel rechristened business administration as strategic management in 1978. In recent times, the role of strategic leadership in schools has earned greater signifi cance as a result of the international trends towards school-based management (SBM); reforms in school governance requiring school leaders to adopt business-like practices, including developing an organizational vision, strategic planning, marketing, listening to customers and observing market trends; greater autonomy and self governance altering the school leadership paradigm; and education systems recognising the need to have leaders trained in management. It is argued here that strategic leadership is not a new or different form of leadership, but rather, a leadership imperative for all school leaders regardless of their chosen leadership style.
CHEOPS: Cultural Heritage Enhancement Over Cyber-Physical Systems

The Internet of Things (Iot) field has been expanding in various domains with cultural heritage being no exception. Nevertheless, cultural heritage sites are still often managed in traditional ways and a prominent gap remains between tour managers and visitors in correctly identifying visitors interest to specific sites and monuments. Previous related works focused on tackling mood detection separately from particular touristic locations which lead to overly generalized assumptions. Accordingly, in this paper, we propose a comprehensive platform named CHEOPS to enhance the touristic experience by detecting the tourists interest in the sites. The proposed platform provides a customized tour through touristic sites by using indoor localization techniques coupled with information about smartphone activity. Accordingly, the visitor is directed to a more interesting location. In addition to interest detection, CHEOPS implements several techniques for interaction with the touristic site such as gaze detection, gesture recognition, and augmented reality. A prototype of the proposed platform is implemented and tested in real scenarios to detect the usability of the system. The output accurately detects the interest of the users, which can then be used to fill the gap between the site manages and the tourists.
An Efficient Gain Enhancement Approach for 60-GHz Antenna Using Fully Integrated Vertical Metallic Walls in LTCC

The gain of antenna array operating at 60 GHz using low temperature cofired ceramic (LTCC) technology is enhanced, by introducing a simple, low-profile, and low-loss structure. Part of the radiated waves in the antenna array's E-plane is in-phase reflected, by fully integrated vertical metallic walls. Consequently, an improved gain performance can be obtained. The substrate integrated waveguide slot antenna array is implemented for demonstrations. Those vertical metallic walls, created by cofabricated open-air cavities, are placed at either side along the H-plane of slot radiators. Investigations were conducted on those key parameters of a single-slot antenna with two vertical metallic walls, in order to have a better understanding on the effect of the walls. Two prototypes, which are a 1 × 8 (1-D) and a 4 × 8 (2-D) waveguide slot antenna array, have been separately developed for verifications. The dimensions of the developed antenna arrays are determined based on a compromise between the performance and the fabrication restraint in the LTCC process. Both antenna arrays can efficiently transmit data within a 1000 MHz (59.5-60.5 GHz) bandwidth for some narrow band applications. When compared with conventional antenna arrays without metallic walls, the proposed approach can achieve gain enhancement of about 4.4 dB for the 1-D case and 2.5-3.1 dB for the 2-D case, across the impedance bandwidth.
PV Tracker System Net Gain Associated to the Local Climatic Conditions

: The optimization procedure on a photovoltaic system design implies the best compromise between energetic production (EP) and overall associated costs (OAC), which include economic and environmental. Both variables depend on the available solar radiation; strongly the EP and, in a lesser extent, the OAC. In this paper, the required conditions so that a PV tracking system produces a net gain with respect to a PV fixed system will be evaluated. This analysis is performed as function of the location’s climatic conditions in terms of production and associated multidimensional costs, including EPBT and IRR. To avoid theoretical model dependences, the whole study has been carried out under real sun conditions on a medium irradiation region. For it, an 8-month historical monitoring data of a grid-connected PV field have been analyzed. The installation has two same-manufacturer polycrystalline arrays installed the same year, one of them with a 2-axis tracker and the other in fixed tilt position. As general result, a simple algorithm for tracker net gain evaluation as function of global and diffuse radiation is provided. Also, the net benefit limit value for a tracker system as function of the diffuse fraction is calculated.

Role of the Adenovirus DNA-Binding Protein in In Vitro Adeno-Associated Virus DNA Replication

ABSTRACT A basic question in adeno-associated virus (AAV) biology has been whether adenovirus (Ad) infection provided any function which directly promoted replication of AAV DNA. Previously in vitro assays for AAV DNA replication, using linear duplex AAV DNA as the template, uninfected or Ad-infected HeLa cell extracts, and exogenous AAV Rep protein, demonstrated that Ad infection provides a direct helper effect for AAV DNA replication. It was shown that the nature of this helper effect was to increase the processivity of AAV DNA replication. Left unanswered was the question of whether this effect was the result of cellular factors whose activity was enhanced by Ad infection or was the result of direct participation of Ad proteins in AAV DNA replication. In this report, we show that in the in vitro assay, enhancement of processivity occurs with the addition of either the Ad DNA-binding protein (Ad-DBP) or the human single-stranded DNA-binding protein (replication protein A [RPA]). Clearly Ad-DBP is present after Ad infection but not before, whereas the cellular level of RPA is not apparently affected by Ad infection. However, we have not measured possible modifications of RPA which might occur after Ad infection and affect AAV DNA replication. When the substrate for replication was an AAV genome inserted into a plasmid vector, RPA was not an effective substitute for Ad-DBP. Extracts supplemented with Ad-DBP preferentially replicated AAV sequences rather than adjacent vector sequences; in contrast, extracts supplemented with RPA preferentially replicated vector sequences.
Evaluation of criteria for temporary external fixation in risk-adapted damage control orthopedic surgery of femur shaft fractures in multiple trauma patients: "evidence-based medicine" versus "reality" in the trauma registry of the German Trauma Society.

BACKGROUND Femur-shaft fracture treatment (FSFT) follows controversial management concepts after multiple trauma: primary-definitive osteosynthesis, secondary-definitive osteosynthesis after temporary external fixation (EF) in all patients, or individualized primary- or secondary-definitive osteosynthesis ("risk-adapted damage control orthopedics"). This study compares the concepts by analyzing literature evidence and a prospective multicenter database. METHODS A systematic literature analysis was performed. The German Trauma Society trauma registry was used to assess variables predictive of treatment concept. RESULTS Contradictory results in 63 controlled trials failed to support a "generalized management strategy. " In all, 1,465 FSFTs in 8,057 trauma registry patients (age 39 +/- 19.5 years; Injury Severity Score [ISS] 23.5 +/- 14.9; 17.3% mortality) were treated initially (<24 hour) by EF, nail, or plate in 47.0%, 41.1%, and 11.9%, respectively. Despite large interhospital variability, EF was more likely with increasing severity of ISS, Glasgow Coma Score, thorax trauma, base excess, coagulation abnormalities, and initial probability of death. CONCLUSIONS Clinical "reality" reflects the controversies of "scientific evidence" for FSFT after multiple trauma in Germany. Although decision making is currently based on unvalidated criteria, anatomic and physiologic injury severity appears to influence the choice of management concept.
A reduction in hippocampal GABAA receptor α5 subunits disrupts the memory for location of objects in mice

The memory for location of objects, which binds information about objects to discrete positions or spatial contexts of occurrence, is a form of episodic memory particularly sensitive to hippocampal damage. Its early decline is symptomatic for elderly dementia. Substances that selectively reduce α5‐GABAA receptor function are currently developed as potential cognition enhancers for Alzheimer's syndrome and other dementia, consistent with genetic studies implicating these receptors that are highly expressed in hippocampus in learning performance. Here we explored the consequences of reduced GABAAα5‐subunit contents, as occurring in α5(H105R) knock‐in mice, on the memory for location of objects. This required the behavioral characterization of α5(H105R) and wild‐type animals in various tasks examining learning and memory retrieval strategies for objects, locations, contexts and their combinations. In mutants, decreased amounts of α5‐subunits and retained long‐term potentiation in hippocampus were confirmed. They exhibited hyperactivity with conserved circadian rhythm in familiar actimeters, and normal exploration and emotional reactivity in novel places, allocentric spatial guidance, and motor pattern learning acquisition, inhibition and flexibility in T‐ and eight‐arm mazes. Processing of object, position and context memories and object‐guided response learning were spared. Genotype difference in object‐in‐place memory retrieval and in encoding and response learning strategies for object–location combinations manifested as a bias favoring object‐based recognition and guidance strategies over spatial processing of objects in the mutants. These findings identify in α5(H105R) mice a behavioral–cognitive phenotype affecting basal locomotion and the memory for location of objects indicative of hippocampal dysfunction resulting from moderately decreased α5‐subunit contents.
