Hybrid triad provides fracture plane stability in a computational model of a Pauwels Type III hip fracture

Abstract The study utilized finite element method to determine displacements and stresses in a set of Pauwels Type III femoral neck fractures repaired using 3 techniques (cannulated screws (Triad), sliding hip screw (SHS), and a Hybrid (SHS + cannulated screws). The research found that shear displacement doubled between the 65° and 75° fracture angles regardless of fixation construct. The SHS alone was the least stable construct, with highest construct stresses and shear displacement along the fracture plane. The stability of the Hybrid and Triad constructs were similar, but stress in the Hybrid was lower suggesting it would provide a higher load to failure than the Triad.
Dynamic cerebral autoregulation across the cardiac cycle during 8 hr of recovery from acute exercise

Current protocols examining cerebral autoregulation (CA) parameters require participants to refrain from exercise for 12–24 hr, however there is sparse objective evidence examining the recovery trajectory of these measures following exercise across the cardiac cycle (diastole, mean, and systole). Therefore, this study sought to determine the duration acute exercise impacts CA and the within‐day reproducibility of these measures. Nine participants performed squat–stand maneuvers at 0.05 and 0.10 Hz at baseline before three interventions: 45‐min moderate‐continuous exercise (at 50% heart‐rate reserve), 30‐min high‐intensity intervals (ten, 1‐min at 85% heart‐rate reserve), and a control day (30‐min quiet rest). Squat–stands were repeated at hours zero, one, two, four, six, and eight after each condition. Transcranial doppler ultrasound of the middle cerebral artery (MCA) and the posterior cerebral artery (PCA) was used to characterize CA parameters across the cardiac cycle. At baseline, the systolic CA parameters were different than mean and diastolic components (ps < 0.015), however following both exercise protocols in both frequencies this disappeared until hour four within the MCA (ps > 0.079). In the PCA, phase values were affected only following high‐intensity intervals until hour four (ps > 0.055). Normalized gain in all cardiac cycle domains remained different following both exercise protocols (ps < 0.005) and across the control day (p < .050). All systolic differences returned by hour six across all measures (ps < 0.034). Future CA studies may use squat–stand maneuvers to assess the cerebral pressure–flow relationship 6 hr after exercise. Finally, CA measures under this paradigm appear to have negligible within‐day variation, allowing for reproducible interpretations to be drawn.

STUDY OF MICROPHONICS COMPENSATION FOR SRF CAVITY*

Microphonics and Lorentz Force detune the resonance frequency of a SRF cavity, leading to perturbations of the amplitude and phase of its accelerating field. Although this disturbance could be compensated by a piezo-electric tuner or with additional RF power, these two methods have conflicts, which is observed as unstable RF fields in a recent experiment. These conflicts could be explained by a model. Further experiments on ReA3 [1] cryomodule validates a conflict suggested by the model. Overall optimization of control algorithm is still needed to effectively combine the two methods.
Ontology engineering methodologies for the evolution of living and reused ontologies: status, trends, findings and recommendations

Abstract The aim of this critical review paper is threefold: (a) to provide an insight on the impact of ontology engineering methodologies (OEMs) to the evolution of living and reused ontologies, (b) to update the ontology engineering (OE) community on the status and trends in OEMs and of their use in practice and (c) to propose a set of recommendations for working ontologists to consider during the life cycle of living, evolved and reused ontologies. The work outlined in this critical review paper has been motivated by the need to address critical issues on keeping ontologies alive and evolving while these are shared in wide communities. It is argued that the engineering of ontologies must follow a well-defined methodology, addressing practical aspects that would allow (sometimes wide) communities of experts and ontologists to reach consensus on developments and keep the evolution of ontologies ‘in track’. In doing so, specific collaborative and iterative tool-supported tasks and phases within a complete and evaluated ontology life cycle are necessary. This way the engineered ontologies can be considered ‘shared, commonly agreed and continuously evolved “live” conceptualizations’ of domains of discourse. Today, in the era of Linked Data and Knowledge Graphs, it is more necessary than ever not to neglect to consider the recommendations that OEMs explicitly and implicitly introduce and their implications to the evolution of living ontologies. This paper reports on the status of OEMs, identifies trends and provides recommendations based on the findings of an analysis that concerns the impact of OEMs to the status of well-known, widely used and representative ontologies.
Building on shaky foundations? Lack of falsification and knowledge contestation in IS theories, methods, and practices

ABSTRACT Among the defining characteristics of a healthy research discipline is the ability to correct its knowledge if more recent evidence creates grounds for this. Studies that reveal errors in earlier theories demonstrate, in line with Karl Popper’s thinking, an approach called falsificationism. They complement approaches aimed at developing and expanding knowledge by generalising empirical observations or postulating new contributions and testing them. The paper presents an analysis that applies this categorisation to abstracts of research papers (N = 5,202) in the eight leading IS journals. Machine-learning-based classification determined that only 7.0% of the papers manifested any clear form of knowledge-contestation, such as falsification, in the approach or findings presented. In light of this, we call on IS researchers to increase the falsification and knowledge-contestation in their research, to nurture more valid theories, methods, and practices, thereby achieving greater societal impact. We present two suitable IS research designs accordingly: knowledge-contesting comparisons and knowledge-contesting replications. We also discuss how these designs, exemplifying opportunities to increase the number of knowledge-contesting studies in the field, can be applied in both positivist and interpretivist research epistemology.

Brugia malayi is a filarial parasite that causes lymphatic filariasis in human beings. Kerala (India) is endemic for human Brugian filariasis. B. malayi microfilariae, similar to that causing filariasis in human beings, have been identified in dogs in Kerala. This is the first report of western blotting analysis of canine B. malayi microfilarial proteins. SDS PAGE analysis of B. malayi microfilarial protein revealed 5 major protein bands with molecular weights of 125, 80, 64, 54 and 27 kDa. Among these, the prominent bands were those having molecular weights of 64, 54 and 27 kDa. We raised polyclonal antibodies against these somatic proteins of dog microfilariae in a rabbit. The polyclonal antibodies recognized predominantly the 54 kDa and 64 kDa antigens in a Western blot analysis. Based on previous publications with B. malayi, these two protein bands appear to be important for diagnosis and for vaccine development against lymphatic filariasis.
Conceptualisation and validation of system use reduction as a self-regulatory IS use behaviour

ABSTRACT Focusing on social networking site (SNS) users, this research conceptualizes, theorizes on and tests information systems (IS) use reduction herein defined as users’ attempt to reduce their use of an IS to levels that seem reasonable to them to avoid negative implications. IS use reduction is more realistic for many users than full discontinuance, more prevalent than many other corrective behaviors, and can have many desirable outcomes. Yet, knowledge regarding this behavior has been limited. It therefore warrants more attention in IS research and a growing need to develop interventions aimed at helping users reducing excessive IS use such as SNSs. We suggest that IS use reduction can be motivated by negative consequences of excessive SNS use and that the way users translate such states into SNS use reduction intentions can be explained by a contextual and nuanced adaptation of Bandura’s self-regulation of motivation and self-reactive framework. A survey study (study 1, n=257) was used to theorize and test the determinants of SNS use reduction intentions, and a longitudinal experimental study (study 2, n=127) extended the validity of the survey study findings, established causality and examined whether the manipulation the survey study predictors can produce actual SNS use reduction.
Risk, Sex Differences and Self-Employment

In this paper, we examine the role of risk preferences and wealth on the decision of becoming an entrepreneur. In the first instance, we focus our analysis on Poland a country which has undergone very large societal changes. The transition environment in this country provides an interesting setting for examining the changing level of selfemployment (Masters and Meier (1988)). We compare differences among female and male entrepreneurs to identify the reasons for becoming self-employed. Past studies suggest that whilst for men the decision to enter self-employed is mostly income-driven (improvement of economic situation), a significant fraction of women decide to become self-employed trading off income for a more flexible work arrangement and other nonpecuniary benefits associated with self-employment. First, we compare our measures of risk by gender and then model the decision to become an entrepreneur for women and men separately. To our knowledge this is the first paper to attempt this type of analysis on the propensity of becoming self-employed using data from a new EU member state. The preliminary results suggest a nonlinear relationship between household wealth (proxied by savings) and the propensity to selfemployment. For men individual risk preferences play an important role where risk takers are more likely to work as self-employed. For women, family composition seems to have a greater effect. In addition, we find that highly educated women with young children are more likely to pursue the entrepreneurial career path. Possibly because it provides them with the opportunity to have flexible work arrangements and allows them to develop their entrepreneurial skills.
Factors Associated with Maternal Behavior in Prevention of the Hand, Foot and Mouth Disease in Young Children, Vietnam

Objective: To examine Vietnamese mothers’ preventive behavior on the Hand, Foot and Mouth Disease (HFMD) for their children and determine the association between such preventive behavior and the mothers’ knowledge about HFMD, self-efficacy, and social support. Method: A cluster random sampling was used to recruit the sample of 97 mothers with young children receiving services at four child care centers in Hai Duong City, Vietnam. Data were collected from August to September 2015. Self-report questionnaires consisted of 1-demographic record, 2-the maternal behavior in prevention of HFMD, 3-the knowledge about HFMD, 4-the perceived self-efficacy and 5-the Multidimensional Scale of Perceived Social Support (MSPSS). Cronbach’s alpha coefficients of questionnaires 2 – 5 were 0.81, 0.81, 0.85 and 0.86, respectively. Descriptive statistics and Pearson correlation coefficients were used for data analysis. Results: Vietnamese mothers had moderate mean score of HFMD preventive behaviors for their children (73.81  8.70). This maternal preventive behavior was positively correlated with knowledge about HFMD, perceived self-efficacy, and social support (r = 0.54, P < 0.01, r = 0.44, P < 0.01 and r = 0.57, P < 0.01, respectively). Conclusion: Vietnamese mothers of young children had moderate score of preventive behaviors on HFMD. The preventive behavior was positively associated with knowledge, self-efficacy, and social support. Nurses could provide knowledge, and promote maternal self-efficacy and social support.Keywords: hand, foot and mouth disease (HFMD), knowledge, self-efficacy, maternal behaviors, prevention, Vietnam
An Investigation of Factors that Influence Willingness to Relocate for Construction Management Students

Workforce mobility is a significant issue for many construction firms. In order to remain competitive, firms must attract skilled employees who are willing to relocate to meet project related demands. Although workforce mobility has been widely researched, little emphasis has been placed on undergraduate construction management students entering the workforce. This study used a descriptive survey research design to investigate how four factors, identified in previous studies, are related to an individuals’ willingness to relocate. The findings suggest that closeness with parents and siblings, and future plans of marriage with family are not significantly related to willingness to relocate. However, respondents seeking opportunities for career enhancement reported being more willing to relocate for work. The results of this study provide valuable insight for college faculty as they prepare students to enter the workforce. The findings will also serve recruiters for construction firms as they seek to identify individuals for opportunities that require relocation. This publication is the product of a faculty/ student collaboration stemming from the McNair Scholars program at the University of Central Missouri.
Tilburg University Loosening the reins or tightening them ?

Background Adolescents face major developmental tasks such as increasing individuation and establishing autonomy. These developmental tasks increase demands on adolescent self-control, hereby putting youth with poor effortful control at risk for psychopathology. Specific parenting behaviors might be warranted to buffer against this risk. Objective This study was designed to examine parenting-related risk and protective factors in the associations between effortful control and adolescent psychopathology. We hypothesized that youth with poor effortful control require more parental involvement (i.e., lower autonomy granting) to help complete these developmental tasks and subsequently avoid psychopathology. Methods Via adolescent self-reports (N = 809), associations between effortful control, perceived parenting (i.e., psychological control and autonomy support), and externalizing (i.e., interpersonal aggression and rule-breaking) and internalizing problems (i.e., depressive and anxiety problems) were examined. Results Regression analyses supported our hypothesis in boys: higher levels of autonomy support exacerbated the negative association between effortful control and rule-breaking. In contrast, in girls this was the case for lower levels of autonomy support. For both genders, low autonomy support and psychological control exacerbated negative associations between effortful control and internalizing problems. No buffering effects of parenting were found. Conclusions Low effortful control is associated with psychopathology in adolescents, but parenting can affect this association in several ways, depending on the type of psychopathology and the adolescent’s gender. Future research should focus on finding ‘optimal’ levels of parental control that can help avoid psychopathological problems in youth with poor effortful control.

How to prove decidability of equational theories with second-order computation analyser SOL

Abstract We present a general methodology of proving the decidability of equational theory of programming language concepts in the framework of second-order algebraic theories. We propose a Haskell-based analysis tool, i.e. Second-Order Laboratory, which assists the proofs of confluence and strong normalisation of computation rules derived from second-order algebraic theories. To cover various examples in programming language theory, we combine and extend both syntactical and semantical results of the second-order computation in a non-trivial manner. We demonstrate how to prove decidability of various algebraic theories in the literature. It includes the equational theories of monad and λ-calculi, Plotkin and Power’s theory of states and bits, and Stark’s theory of π-calculus. We also demonstrate how this methodology can solve the coherence of monoidal categories. Video Abstract A video abstract can be found at: https://vimeo.com/365486403
Biomimetic collagen fibril-based coatings enriched with chitosan

Interactions between a biomaterial implanted in bone and the surrounding bone tissue are dependent on the surface characteristics of the implant. Surface characteristics that promote osteointegration, formation of a direct interface between an implant and bone leading to superior implant fixation, are desirable. Improvement of the attachment, proliferation and differentiation of bone-forming cells are a pre-requisite for formation of new bone tissue, hence surface characteristics which promote these are desirable. Collagen is a fibrillar structural protein in mammalian tissues and chitosan is a polysaccharide derived from marine invertebrate exoskeletons. Both promote cell attachment, proliferation and differentiation, and thus both are suitable as implant coating materials. In this study, collagen-chitosan coatings were formed and their mechanical properties were studied. To our best knowledge, the combination of collagen and chitosan in such coatings is novel. The influence of chitosan on the morphology and the Young’s modulus of collagen-chitosan coatings was investigated. Two different approaches for the formation of the collagen-chitosan coatings were compared. In the first approach, hydrogel formation took place directly on the substrate, and fibrils formed directly on the surface. In the second approach, collagen and chitosan were adsorbed from preformed hydrogels. Larger fibrils were observed through the first approach, while many small fibrils were observed through the second approach. The highest Young’s modulus was observed for collagen coatings containing 0.75-1.5% chitosan. This was true for both approaches, but a higher Young’s modulus was obtained through the first approach. The elastic behavior of collagen-chitosan hydrogels was determined using rheometry, to obtain a deeper understanding of the collagen-chitosan interactions that might influence the adsorbed coatings. The gelation process occurred more slowly for hydrogels containing a higher chitosan concentration. It appeared that the storage modulus was higher for chitosan concentrations of 3-6% in the collagen-chitosan hydrogels. These results pave the way for cell biological characterization of the coatings and may assist in the interpretation of the results.
TITLE : Reconceptualising the principles of Penrose ’ s ( 1959 ) theory and the resource based view of the firm : the generation of a new conceptual framework

Purpose – The purpose of this paper is to develop a conceptual framework to explain the firm growth process based on an integration and extension, through empirical research, of Penrose’s theory of the growth of the firm and the resource-based view. Theoretical development within the firm growth literature has been noticeably limited. Firm growth studies use different theoretical bases and what is needed is integration of multiple theories and empirical testing of these to form a new conceptual framework capable of explaining the modern growth process fully. Design/methodology/approach – The key perspectives are critically reviewed and integrated and empirical qualitative research is undertaken analysing the process of growth in two firms. Semi-structured interviews, participant observation and analysis of company documentation are utilised. Findings – The key insight this research provides is detailed information with regard to which resources, mediators and outputs are vital to firm growth, how they need to be developed and why this is the case. The study shows that these act in a cyclical nature to enable firm growth and development. Practical implications – These findings could be used by practitioners to determine which part of the conceptual framework requires the most amount of improvement and which are developed to an acceptable state, enabling them to make plans for the achievement of growth. Originality/value – This research is able to reconceptualise two dominant theoretical perspectives resulting in the generation of a new firm growth framework, thereby addressing a distinct gap in the firm growth literature.
An Evaluation of Rapid Methods

An evaluation has been carried out of rapid methods for measuring diffusible weld hydrogen, and the results have been compared with those of the primary room temperature mercury method. Different analytical techniques have been studied looking at extraction temperatures of up to 400°C (752°F), while a range of consumable types for shielded metal arc (SMA), flux cored arc (FCA) and submerged arc welding (SAW) deposits was included. With the exception of welds containing porosity, satisfactory agreement with the primary method was obtained at temperatures up to 400°C, provided appropriate care was taken. Analysis times were markedly reduced from 14 to 21 days at 20°C (68°F) to N 30 min at 400°C.
