The sources of social capital within technology incubators: the roles of historical ties and organizational facilitation

There are currently three divergent views regarding the sources of beneficial social capital within collectivities or networks: historical ties, organizational facilitation, and trust-based shared pursuit of common goals. Technology incubators are newer organizational forms that are created to support and accelerate the development and success of affiliated technology-based ventures. However, it is unclear how social capital that benefits the technological development of affiliated ventures is created within technology incubators. Drawing from the social capital, technology, and organizational learning literature, this study seeks to understand how technology incubators can create social capital that enables accelerated technological learning of affiliated ventures. Based upon a survey of 43 technology-based ventures affiliated with U.S. and Finnish technology incubators, results of this study suggest that facilitated networking support of the technology incubator serves as the primary source of social capital that enables accelerated technological learning of affiliated technology-based ventures. However, results also suggest that less established or newer technology incubators enable accelerated technology learning better than more established incubators. This suggests that technology incubators are not able to maintain historical ties that benefit the technological learning of affiliated ventures.
Cohort Study on the Percutaneous Treatment of Displaced Intra-articular Fractures of the Calcaneus

BACKGROUND To reduce the high rate of soft tissue complications in the treatment of displaced intra-articular fractures of the calcaneus, several minimally invasive techniques have been developed. Little evidence exists on the clinical outcome of these techniques. METHODS We performed a study on a cohort of 46 fractures treated by the 3-point distraction technique. In 41 fractures, clinical outcome was available. Fractures were classified according to the Essex-Lopresti and Sanders classifications. The clinical outcome was determined using the 3 most frequently used outcome scores. RESULTS The clinical outcome of our cohort of percutaneous treated intra-articular calcaneal fractures was good to excellent in 69% with the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale (AOFAS) score. This percentage increases to 100% for tongue type fractures alone but decreases to 52% for joint depression type fractures. Infectious complications occurred in 1 (2.4%) and secondary arthrodesis was needed in 3 fractures (7.3%). The Sanders classification showed no prognostic value. The Essex-Lopresti classification was a strong prognosticator with a median AOFAS score of 92 (interquartile range [IQR], 87.8-97.8) for tongue type fractures and 75 (IQR, 63.0-85.0) for joint depression type fractures (P < .001). CONCLUSION The treatment of displaced intra-articular calcaneal fractures by the 3-point distraction technique was an acceptable alternative to open surgery and other percutaneous techniques. It had a low amount of infectious complications with comparable outcome to open treatment. The computed tomography-based Essex-Lopresti classification had a strong prognostic value when fractures were treated by the 3-point distraction technique. The results of this study support the use of the 3-point distraction technique, especially in tongue type fractures. LEVEL OF EVIDENCE Level IV, retrospective case series.
Cognitive Impairment in Late-Onset Depression

Background: While cognitive dysfunction in late-onset depression (LOD) is common, the nature and determinants of this impairment are heterogeneous. It has been suggested that neuropsychological decrements in LOD patients might result from a deficit in processing resources. In order to address this issue, we analyzed processing resources in LOD to see if their decrease explains higher-level cognition (episodic memory and naming capacity) deficits. Methods: Measures of processing speed, working memory, inhibition, episodic memory and naming capacity were administered to 14 LOD inpatients and 14 controls. Results: The LOD patients performed significantly worse than the controls in all domains except for inhibition. Hierarchical regression analyses showed that naming capacity impairment was totally mediated by processing speed and working memory, whereas episodic memory dysfunction was only partially mediated by working memory. Conclusion: The reduction in certain processing resources (working memory, processing speed) in late-onset depressed patients appears to mediate impairments in episodic memory and naming capacity. However, episodic memory impairment cannot only be explained by processing resource decrement in LOD patients, suggesting that a primary episodic memory dysfunction is present in this condition.
Avirulence of Candida albicans FAS2 mutants in a mouse model of systemic candidiasis

Disruption of both alleles of the Candida albicans FAS2 gene abolishes the ability of the organism to establish infection in a murine model of systemic candidiasis. Within 72 h all mice inoculated with 10(6) CFU of the parental C. albicans strain had died. In contrast, all animals inoculated with the mutant strain CFD2 survived for the course of the experiment (21 days). Animals infected with either mutant strain CFD1 or CFD3, in which only one FAS2 allele was disrupted, also succumbed to infection, but mortality was not observed until 4 days postinfection and survivors remained for up to 20 days postinfection. The results demonstrate that FAS2 is required for successful C. albicans infection.
A twin study of inattentive, aggressive, and anxious/depressed behaviors.

OBJECTIVE To estimate genetic, environmental, and rater contrast influences on parental report of Attention Problems (AP), Aggressive (Agg), and Anxious/Depressed (AxD) behaviors of 492 twin pairs assessed with the Child Behavior Checklist. METHOD A parent (92% mothers) of twins aged 8 to 12 years completed the Child Behavior Checklist. Genetic, shared and unique environmental, and rater bias effects were estimated for the AP, Agg, and AxD syndromes. Data on boys and girls were analyzed separately. Results were compared to prior research on related DSM disorders. RESULTS Estimates of genetic influences on AP (60%-68%), Agg (70%-77%), and AxD (61%-65%) were high for both sexes, but lower for AP than prior findings using DSM attention-deficit hyperactivity disorder (ADHD). However, unlike equivalent analyses of DSM ADHD based on parental report, there was no evidence of rater bias. CONCLUSIONS Estimates of genetic influence on these common child psychopathological domains were high. There was no evidence of rater contrast effects. These findings have implications for diagnosis, particularly when assessing families with multiple children.
Superfluidity of a nonequilibrium Bose-Einstein condensate of polaritons

We study theoretically superfluidity in a driven-dissipative Bose gas out of thermal equilibrium, and discuss the relation with conventional superfluids. We show how the superfluid behavior is characterized by a dramatic increase in the lifetime of a quantized vortex and point out the influence of the spatial geometry of the condensate. We apply our study to a condensate of polaritons in a semiconductor microcavity, whose properties can be directly inferred from optical spectroscopy. We propose three different experimental schemes to measure the vorticity of the polariton condensate.
THE ROLE OF BUSINESS PROCESSES AND ENTERPRISE ARCHITECTURES IN THE DEVELOPMENT OF ORGANIZATIONAL SELF-AWARENESS

This paper is about a partnership between two disciplines: organizational studies and information systems engineering. It is argued that organizational studies has much to benefit from the conceptual development that has been taking place in the representation of organizational processes and enterprise architectures (EA) and that systems engineering can greatly expand its execution capability by absorbing a variety of messages coming from social or organizational theory. The concept of Organizational Self-Awareness (OSA) is offered as the contextual framework for the discussion. OSA is a process which involves, firstly, the efforts of the individual organizational member in getting to know his/her work environment, through sensemaking. Sensemaking is influenced by a number of factors, some related to the individual’s psychological makeup, others related to the individual’s work environment. EAs can play a relevant role in sensemaking. From activity theory the paper highlights the process of consciousness formation in human beings as well as the mediating artefacts that shape and constrain the acquisition, accumulation and development of knowledge and self-knowledge. Among the many mediating artefacts in the work environment EAs are a special type. EAs are also boundary objects due to their distinctive ability to influence perspective making and perspective taking in the process of organizational sensemaking. The paper concludes that the design and use of EAs can play a crucial role in the formation of a collective mind about the state of the organizational processes and therefore about the state of the organization.
Social-Aware Data Collection Scheme Through Opportunistic Communication in Vehicular Mobile Networks

To enable the intelligent management of Smart City and improve overall social welfare, it is desirable for the status of infrastructures detected and reported by intelligent devices embedded in them to be forwarded to the data centers. Using “SCmules” such as taxis, to opportunistically communicate with intelligent devices and collect data from the sparse networks formed by them in the process of moving is an economical and effective way to achieve this goal. In this paper, the social welfare data collection paradigm SWDCP-SCmules data collection framework is proposed to collect data generated by intelligent devices and forward them to data centers, in which “SCmules” are data transmitters picking up data from nearby intelligent devices and then store-carry-forwarding them to nearby data centers via short-range wireless connections in the process of moving. Because of the storage limitations, “SCmules” need to weigh the value of data and select some less valuable data to discard when necessary. To quantify the value of data and find a well-performed selection strategy, the concept of priority is introduced to the SWDCP-SCmules scheme, and then, the simulated annealing for priority assignment SA-PA algorithm is proposed to guide the priority assignment. The SA-PA algorithm is a universal algorithm that can improve the performance of SWDCP-SCmules scheme by finding better priority assignment with respect to various optimization targets, such as maximizing collection rate or minimizing redundancy rate, in which priority assignment problem is converted into an optimization problem and simulated annealing is used to optimize the priority assignment. From the perspective of machine learning, the process of optimization is equal to automatically learn social-aware patterns from past GPS trajectory data. Experiments based on real GPS trajectory data of taxis in Beijing are conducted to show the effectiveness and efficiency of SWDCP-SCmules scheme and SA-PA algorithm.
The Course of Migraine—A Diary Study in Unselected Patients

The course of disease and the predictive value of depression and anxiety in patients with migraine were prospectively examined. We recruited 393 migraineurs through articles in newspapers and performed a follow-up examination 30 months later. At baseline and follow-up, patients underwent a semi-structured interview, filled out the Headache Impact Test (HIT-6), Self-rating Depression Scale (SDS) and Self-rating Anxiety Scale (SAS) and they kept a headache diary for 30 days. One hundred and fifty-one patients (38.6%) were seen at follow-up. The baseline data of patients with and without follow-up were comparable. At follow-up the number of headache days per month had decreased from 9.6 ± 5.8 to 8.1 ± 6.3 (P < 0.001) and the proportion of patients with chronic headache (15.4%) and medication overuse (13%) had remained stable. SDS and SAS scores were associated with a high migraine frequency and high initial SDS scores predicted high migraine frequency at follow-up. This longitudinal study in unselected patients with migraine not excluding subjects with chronic headache, medication overuse, depression or anxiety does not point towards migraine as a progressive disease in the vast majority of patients and confirms the importance of psychiatric comorbidity.
Rheological and mechanical properties of self-compacting concrete with the addition of nano-silica and microsilica

© 2016 ALCONPAT International ABSTRACT Self-compacting concrete is the result of the redesign of quality mixtures with the ability to ensure its correct placement in strongly assembled structures, where the vibration process is too complicated and where there is the risk of altering the position of the reinforcement bars. Along with the advantages of this concrete and due to the greater demand for high performance concrete, silica fume is used, and more recently, nanomaterials with nano-silica as well; mainly, nano-silica. The objective of this work is to obtain self-compacting concretes with nano-silica, silica fume and binary mixtures of both, which satisfy the demands for high mechanical resistance and durability, determining that the dosage with the best features contains: 2.5% of nano and 2.5% of silica fume.
Technology readiness and mobile self-service technology adoption in the airline industry: An emerging market perspective

Orientation: While mobile applications are seen as the way forward for airlines and airports alike, not much is known about consumers’ readiness to adopt such self-service technologies. This is important because of lower than expected adoption rates of traditional self-service technologies (online websites and check-in kiosks) in the airline industry.Research purpose: The purpose of this study was to determine passengers’ level of technology readiness and its influence on their adoption of mobile self-service technologies in the airline industry of South Africa.Motivation for the study: To ensure the adoption of mobile self-service technologies in the airline industry, it is necessary to uncover consumers’ readiness and adoption behaviours towards such technologies.Research design, approach and method: Primary data were collected from 315 respondents using a structured questionnaire. The sample comprised South African citizens who had travelled using an airline either domestically or internationally within the previous 12 months. Regression analysis was used to test hypotheses posited in the study.Main findings: The findings showed that airline self-service mobile application adoption is influenced by technology readiness, perceived ease of use and perceived usefulness; both perceived ease of use and perceived usefulness are influenced by technology readiness; and perceived ease of use strongly influences perceived usefulness regarding airline mobile self-service application adoption.Practical/managerial implications: Effective communication aimed at enhancing the perception that airline self-service mobile applications are easy to use is essential to increase the adoption of mobile applications in the airline industry.Contribution/value-add: The article contributed by applying the TRAM construct to the use and adoption of self-service mobile applications in the airline industry. In addition, the study also integrated the recently refined TRI 2.0 into the TRAM construct (TRAM 2.0).
The Study of False Memories: Historical Reﬂ ection

This work consists of a theoretical review with the aim of historically framing the way false memories have been studied. Although most of the studies on false memories have been developed since the last decade of the 20 th century, the earliest is dated from the late 19 th century. With the aim of pointing out the great historical milestones in the research of false memories, the pioneering studies carried out in the 19 th century, as well as the researches on the effect of the questions on the reports of children and adults, are presented. Subsequently, we present the ﬁ rst researches carried out with the speci ﬁ c objective of studying the effect of suggestive questions on the production of false memories, followed by those who used a naturalistic approach and become decisive for the understanding of this phenomenon. In the second half of the 20 th century, a more cognitive approach takes place, and the paradigms of misinformation and DRM arise, which will also be discussed. Throughout the manuscript, it is also re ﬂ ected on the mechanisms that were considered to be the basis of the production of the false memories, as well as on the scienti ﬁ c and social implications of this phenomenon.
Barth on election and the Canons of Dort

The purpose of this contribution is not to give a complete overview of Barth’s doctrine of election. That would be impossible to do in a few pages. The purpose is firstly, to investigate Barth’s explicit references to the Canons of Dort in Kirchliche Dogmatik II/2 (KD II/2), and secondly, to make some remarks on the revisionist character of Barth’s understanding of election. Barth’s use of the Canons of Dort does not seem to attract much scholarly attention. Some historical background are included to create context for the reading of Barth’s understanding of election and references to the Canons of Dort.
Impact of increasing prices of agricultural commodities on poverty

The present paper attempts to identify the groups of households that most likely will face positive or negative welfare consequences as a result of food price increases. Using data from household surveys and differentiating urban from rural areas as well as food buyers from food sellers, the analysis presents preliminary evidence, showing that when the short run effects on consumption are considered, household welfare is expected to decrease, threatening initially food security. Real benefits are expected to occur for selected household groups, as soon as some second round effects, that transform the production structure, are considered. Market participation is critical for small land holders to capitalize potential benefits. Irregular wage earners may also gain from the price increases as long as expansion of the food producing sectors takes place in the parts of the developing countries that agriculture is the dominant source of income. Nevertheless it cannot be neglected that appropriation of the benefits, requires sufficient transmission of the price increases to the farm gate. On the other hand, and unless substantive action is taken, urban poverty is expected to increase given that almost uniformly, populations in such areas are net buyers of food.
Genetic reduction of striatal-enriched tyrosine phosphatase (STEP) reverses cognitive and cellular deficits in an Alzheimer’s disease mouse model

Alzheimer's disease (AD) is a progressive and incurable neurodegenerative disorder. Early in the pathophysiology of AD, synaptic function is disrupted by soluble Aβ oligomers, possibly through Aβ-mediated internalization of NMDA receptors. Striatal-enriched phosphatase (STEP) is a tyrosine phosphatase that regulates the internalization of NMDA receptors. Recent work shows that STEP is elevated in the prefrontal cortex of human AD patients and in animal models of AD. Here, we use genetic manipulations to reduce STEP activity in a triple transgenic AD mouse model and show that a decrease in STEP levels reverses cognitive and cellular deficits observed in these mice. Our results suggest that STEP inhibitors may prove therapeutic for this devastating disorder.
Proportion of drainage of the nutritive solution in the yield and quality of tomato in hydroponics

The limited availability of water, which is becoming more and more severe worldwide, demands a more efficient use of water in agricultural production. The closed hydroponic systems make a more efficient use of water, where the surplus nutrient solution is recovered, regenerated and reused in the same crop. The objective of this research was to know the effects on production and fruit quality with six percentages of drainage (%D): 25, 30, 40, 45, 55 and 60% D of the nutrient solution in a tomato crop. Pots with a fine pearlite substrate previously used were used. The research was carried out in 2016 in the Academic Unit of Agronomy of the Autonomous University of Zacatecas. The number, size, weight and yield of fruits, water productivity and fruit quality (electric conductivity, hydrogen potential, soluble solids, acidity and juice maturity index) were measured in two stages of production. There was a significant difference in yield and quality for treatments 3 and 4 and 1 and 2 respectively. With %D of 40% higher yield was obtained, but with 25% of drainage the content of salts and sugars in fruit was increased and the highest productivity is obtained with respect to the other percentages.
M ay 2 01 9 Non-Relativistic and Relativistic Equations for the Kratzer Potential plus a Dipole in 2 D Systems

In this work, we study the wave equations in 2D Euclidian space for a new non-central potential consisting of a Kratzer term and a dipole term V (r, θ) = Qr−1+Drr −2+Dθ cos(θ)r . For Schrodinger equation, we obtain the analytical expressions of the energies and the wave functions of the system. For Klein-Gordon and Dirac equations, we do the study in both spin and pseudo-spin symmetries to get the eigenfunctions and the eingenvalues. Then we study the dependence of energies on the parameters Dr and Dθ. We find that the Dθ term tends to dissociate the system, and thus counteracts the Coulomb binding effect, and that the Dr term can either amplify or decrease this effect according to its sign.
Investigating retention and workplace implementation of board game learning in employee development

Orientation: Business simulation games for the development of learners take many forms, such as video games and computer games, and are popular choices in academia. The board game, however, is an underutilised educational tool in the development of employees.Research purpose: The retention of board game learning long after the intervention, and the workplace implementation of the decisions it has involved, is an area neglected by academia.Motivation for the study: This study wanted to determine if board games are an effective teaching tool by investigating retention and workplace learning of board games.Research design, approach and method: This qualitative study used descriptive interpretation and deductive content analysis based on two group interviews conducted 1 year after the board game was played.Main finding: This study showed that the participants retained and implemented the learning long after the board game intervention. It is a practical, interactive way to encourage teamwork and allows participants to learn and implement decisions.Practical and managerial implications: Company executives should consider board games as an alternative to traditional educational methods of developing employees.Contribution or value-add: This study showed overwhelmingly that employees still remember the board game 1 year after the intervention and implemented some of its learning in the workplace.
