The Influence of Moral Orientation and Relational Risk on Knowledge Sharing in Supply Chains

Sharing knowledge through inter-organizational relationships is one means of enhancing strategic competitiveness. It is generally agreed that the development of close relationships facilitates such sharing among partners. This paper presents a research model comprises five research hypotheses with four constructs, including moral orientation, opportunistic behavior, loss of competences risk and knowledge sharing. This study develops a conceptual model that relational risk as a mediating construct to examine the inter-relationship effects that affect knowledge sharing and these relationships. We analyze data collected from 281 major manufacturing firms in Taiwan, using structural equation modeling. The results of the empirical study suggest that the role played by moral orientation is critical in ensuring the knowledge sharing as it mitigates the opportunistic behavior and loss of competences risk in the process. The findings of the study provide useful insights into how supply chain members should reinforce their collaborative behaviors and activities so as to improve their moral orientation and in turn enhance knowledge sharing for the supply chain as a whole.
Shoulder-specific outcomes 1 year after nontraumatic full-thickness rotator cuff repair: a systematic literature review and meta-analysis

Background Nontraumatic full-thickness rotator cuff tears are commonly initially treated conservatively. If conservative treatment fails, rotator cuff repair is a viable subsequent option. The objective of the present meta-analysis is to evaluate the shoulder-specific outcomes one year after arthroscopic or mini-open rotator cuff repair of nontraumatic rotator cuff tears. Methods A literature search was conducted in PubMed and EMBASE within the period January 2000 to January 2017. All studies measuring the clinical outcome at 12 months after nontraumatic rotator cuff repair of full-thickness rotator cuff tears were listed. Results We included 16 randomized controlled trials that met our inclusion criteria with a total of 1.221 shoulders. At 12 months after rotator cuff repair, the mean Constant score had increased 29.5 points; the mean American Shoulder and Elbow Score score increased by 38.6 points; mean Simple Shoulder Test score was 5.6 points; mean University of California Los Angeles score improved by 13.0 points; and finally, mean Visual Analogue Scale score decreased by 4.1 points. Conclusions Based on this meta-analysis, significant improvements in the shoulder-specific indices are observed 12 months after nontraumatic arthroscopic or mini-open rotator cuff repair.
Cost utility of behavioural activation delivered by the non-specialist

Summary Behavioural activation by non-specialists appears effective in the treatment of depression. We examined incremental cost-effectiveness of behavioural activation (n = 24) v. treatment as usual (n = 23) in a randomised controlled trial. Intention-to-treat analyses indicated a quality-adjusted life-year (QALY) difference in favour of behavioural activation of 0.20 (95% CI 0.01–0.39, P = 0.042), incremental cost-effectiveness ratio of £5756 per QALY and a 97% probability that behavioural activation is more cost-effective at a threshold value of £20 000. Results are promising for dissemination of behavioural activation but require replication in a larger study.
The Economic Effects of Long-Term Climate Change: Evidence from the Little Ice Age

Recent studies consistently find important economic effects of year-to-year weather fluctuations. I study the economic effects of long-term and gradual climate change over 250 years in the Little Ice Age (1600–1850), during which people and economies had time to adapt. Results show significant negative economic effects of long-term climate change. Temperature impacted the economy through its effect on agricultural productivity and mortality. To adapt to the Little Ice Age, economies increased trade and changed land use. I discuss the relevance of these results for understanding the impact of today’s climate change, especially in developing countries.
Tell Me About Yourself: The Malicious CAPTCHA Attack

We present the malicious CAPTCHA attack, allowing a rogue website to trick users into unknowingly disclosing their private information. The rogue site displays the private information to the user in obfuscated manner, as if it is a CAPTCHA challenge; the user is unaware that solving the CAPTCHA, results in disclosing private information. This circumvents the Same Origin Policy (SOP), whose goal is to prevent access by rogue sites to private information, by exploiting the fact that many websites allow display of private information (to the user), upon requests from any (even rogue) website. Information so disclosed includes name, phone number, email and physical addresses, search history, preferences, partial credit card numbers, and more. The vulnerability is common and the attack works for many popular sites, including nine out of the ten most popular websites. We evaluated the attack using IRB-approved, ethical user experiments.
Indicadores utilizados em saúde bucal no Brasil

Decorridos 25 anos da instituicao do Sistema de Unico de Saude (SUS) no Brasil, os gestores e servidores deste sistema tem concentrado esforcos para superar os desafios em relacao a provisao de servicos de saude com equidade e eficiencia. O planejamento pode contribuir com a gestao, para evitar que as acoes sejam implementadas de forma aleatoria, nao adequadas com a realidade da populacao ou sem definicao de prioridades. Diante disso, os gestores do SUS necessitam de indicadores de saude criados para facilitar a avaliacao, mensuracao ou representacao da condicao de saude, bem como o desempenho de um sistema de saude. O objetivo deste estudo foi analisar os indicadores utilizados em saude bucal no Brasil presentes nas diretrizes governamentais e nos artigos cientificos publicados entre 2000 e 2012. O estudo configurou como uma revisao de literatura na base de dados da Lilacs e Scielo e uma pesquisa documental no sitio eletronico do Ministerio da Saude. Os indicadores que emergiram dos artigos cientificos analisados (n=221) foram categorizados em: condicao de saude bucal, socioeconomicos, demograficos e gestao. Em 34% destes artigos foram identificados indicadores de gestao classificados nas dimensoes: oferta, demanda e desempenho dos servicos. Dentre os indicadores de gestao os mais citados foram o acesso a consulta odontologica, motivo da utilizacao dos servicos e tipo de servico utilizado; dentre os socioeconomicos a renda e o desenvolvimento humano; nos demograficos, faixa etaria e genero; e nos de condicao de saude bucal, o CPOD e GOHAI. Das diretrizes documentais cita-se o Pacto de Indicadores da Atencao Basica; os Pactos pela Saude e o Programa Nacional de Melhoria do Acesso de Qualidade da Atencao Basica (PMAQ). Dentre os indicadores das diretrizes tem-se cobertura de primeira consulta odontologica, acao de escovacao dental supervisionada e cobertura das equipes de saude bucal. Na triangulacao de fontes identificou-se os indicadores coincidentes nos artigos e diretrizes governamentais. Conclui-se que ha uma variedade de indicadores com diferentes formas de calculos, instrumento de coleta e fonte de informacao. A gestao deve priorizar os indicadores com fonte e coleta facilmente disponibilizada. Diferentes denominacoes para os indicadores foram encontradas nos artigos cientificos, necessitando de padronizacao dos termos relacionados ao tema, alem dos aspectos referentes a sua forma de calculo. As diretrizes governamentais trouxeram poucos avancos em termos de propostas de indicadores de saude bucal. Ao longo do tempo, novos indicadores de saude bucal foram instituidos pelo Ministerio da Saude enquanto outros foram excluidos. A publicacao do PMAQ inseriu novos indicadores neste campo que poderao contribuir com a gestao. A descricao dos aspectos metodologicos dos indicadores permitiu a sistematizacao dos procedimentos descritos nos diferentes artigos e publicacoes ministeriais, o que contribuiu com o conhecimento acerca do tema, possibilitando a utilizacao destes indicadores na pratica profissional de gestao e assistencia.
Secondary structure of 5S RNA: NMR experiments on RNA molecules partially labeled with nitrogen-15.

A method has been found for reassembling fragment 1 of Escherichia coli 5S RNA from mixtures containing strand III (bases 69-87) and the complex consisting of strand II (bases 89-120) and strand IV (bases 1-11). The reassembled molecule is identical with unreconstituted fragment 1. With this technique, fragment 1 molecules have been constructed 15N-labeled either in strand III or in the strand II-strand IV complex. Spectroscopic data obtained with these partially labeled molecules show that the terminal helix of 5S RNA includes the GU and GC base pairs at positions 9 and 10 which the standard model for 5S secondary structure predicts [see Delihas, N. , Anderson, J., & Singhal, R. P. (1984) Prog. Nucleic Acid Res. Mol. Biol. 31, 161-190] but that these base pairs are unstable both in the fragment and in native 5S RNA. The data also assign three resonances to the helix V region of the molecule (bases 70-77 and 99-106). None of these resonances has a "normal" chemical shift even though two of them correspond to AU or GU base pairs in the standard model. The implications of these findings for our understanding of the structure of 5S RNA and its complex with ribosomal protein L25 are discussed.
Dual-frequency incoherent subsampling driven test response acquisition of spectrally sparse wideband signals with enhanced time resolution

In this paper, we propose a new test response acquisition technique for high-speed devices-based on dual-frequency incoherent sub-sampling and sparse signal reconstruction. The proposed technique enables reconstruction of spectrally sparse wideband signals such as multi-tone signals and short pseudo-random bit sequences (PRBS) with enhanced time/frequency resolution as opposed to current methods. The sampling hardware utilizes dual analog-to-digital converters (ADCs) and dedicated sampling frequency synthesizers with a common frequency reference. As compared to other compressive sampling architectures [1], the proposed hardware architecture is easy to implement at low cost since it does not require accurate sampling clock phase adjustment or random timing generation. For digital signal reconstruction, the proposed technique requires less number of waveform samples than conventional equivalent-time sampling techniques. In addition, the use of an resolution-enhanced discrete Fourier transform (DFT) frame and basis pursuit algorithms minimizes spectral leakage of incoherently sub-sampled signals. This co-design of sampling hardware and signal reconstruction algorithms enables testing of spectrally sparse wideband signals with enhanced time/frequency resolution.
A new hybrid fault detection technique for systems-on-a-chip

Hardening SoCs against transient faults requires new techniques able to combine high fault detection capabilities with the usual requirements of SoC design flow, e.g., reduced design-time, low area overhead, and reduced (or null) accessibility to source core descriptions. This paper proposes a new hybrid approach which combines hardening software transformations with the introduction of an Infrastructure IP with reduced memory and performance overheads. The proposed approach targets faults affecting the memory elements storing both the code and the data, independently of their location (inside or outside the processor). Extensive experimental results, including comparisons with previous approaches, are reported, which allow practically evaluating the characteristics of the method in terms of fault detection capabilities and area, memory, and performance overheads.
Stability of Atheromatous Plaque Affected by Lesional Composition

Abstract: We examined how lesional composition is related to the stability of coronary plaques. WHHL rabbits (12 months old) were given pravastatin and fluvastatin orally for 52 weeks. Both statins decreased plasma cholesterol levels by about 25%, but the suppressive effects on the degree of coronary plaques were mild. Macrophage (Mφ) contents in fibromuscular cap regions were decreased by pravastatin, and smooth muscle cell (SMC) contents in those were decreased by fluvastatin. The plaque vulnerability index was low in Mφ‐poor plaques, but high in SMC‐poor plaques. Our results suggest that reduction in Mφs in the fibromuscular cap is related to plaque stabilization and that reduction in SMCs in the fibromuscular cap is related to plaque destabilization.
Design of Document Database Systems

This thesis seeks to provide a framework for the design of document database systems. Within this framework we address issues of physical and logical design of document databases and document database systems. These issues include the choice of data model, the query language requirements, physical schema design, logical schema design, and an underlying model of text. Features and inadequacies of some existing data models for representing document databases are identified. We describe two data models based on complex objects. One model is a record-based model used by the Atlas database system, which has been developed at RMIT and The University of Melbourne. We use this model to describe physical storage structures. The other model is a higherlevel object-based model which can be used to describe the logical structure of the database as seen by users, application developers, or database administrators. A text query language (TQL) is described that is based on nested relations, has special text operators, and allows access to complex objects via reference attributes. TQL queries can be directly made on both logical and physical data models for complex objects. We describe a mapping into our logical model from entity-relationship diagrams, and a mapping into our physical data model. The mapping of queries from the logical to the physical level is also addressed. A new approach to logical schema design using complex objects is presented; a resulting logical schema allows easy querying of structured documents and can be mapped into any one of several equivalent nested relational physical schemas. In order to compare the efficiency of different structures for document databases it is desirable to have a reasonably accurate model of document text. A common
Systematic Review and Meta-analysis on Transplantation of Ex Vivo Cultivated Limbal Epithelial Stem Cell on Amniotic Membrane in Limbal Stem Cell Deficiency

Purpose: Ex vivo cultured limbal epithelial transplantation (CLET) with amniotic membrane (AM) as the substrate is a relatively new type of surgical therapy in treating limbal stem cell deficiency (LSCD). We summarize available evidence for determining the efficiency of this technique by a systematic review and meta-analysis. Methods: Searching the following electronic databases, MEDLINE, EMBASE, and the Cochrane Library, we analyzed the selected articles in 5 main aspects: donor screening, culture methods, evidence of cultivated stem cells, subjective symptoms, and adverse events through systematic review. Specifically, meta-analysis was used in evaluating improvements in ocular surface and visual acuity. Results: A total of 18 articles involving 572 eyes of 562 patients were available. The rate of success and 2-line improvement in best-corrected visual acuity (BCVA) was 67% [95% confidence interval (CI), 0.59–0.75; I2 = 60%] and 62% (95% CI, 0.57–0.66; I2 = 37.7%), respectively; and no difference was found both in success rate [odds ratio (OR), 1.35; 95% CI, 0.63–2.89; I2 = 46%] and visual acuity outcome (OR, 1.53; 95% CI, 0.67–3.45; I2 = 42.1%) between autograft and allograft. Conclusions: CLET is efficacious in patients with LSCD, and no difference both in success rate and visual acuity outcome between autograft and allograft was found. Overall safety profile was good, with most side effects being transient and amenable to subsequent treatments. The long-term results of autograft and allograft will inform future treatment algorithms and techniques with random control trials and better-designed analysis.
Heat Transfer to Separation Flow in Heat Exchangers

Separation flow is appeared over and behind a body surface when it is separated from that surface. In separation flow the region is relatively small compared to the body and enclosed by the separating stream line and points of separation and reattachment. Separation flows are formed at the upstream of a forward facing step downstream of a rearward facing step, within a cutout in a body surface and also on the upper surface of an airfoil.
Neurocognitive deficits in decision-making and planning of patients with DSM-III-R borderline personality disorder

Background. Repeated, self-damaging behaviour occurring in the context of borderline personality disorder (BPD) may reflect impairments in decision-making and planning cognition. However, there has been no systematic neuropsychological examination of these particular cognitive functions in patients diagnosed with BPD. Such investigations may improve our understanding of the possible role of brain dysfunction in BPD and improve the characterization of the psychological difficulties associated with this disorder. Method. Forty-two psychiatric patients with a diagnosis of DSM-III-R BPD (41 of whom gave a history of self-harm), without a history of specified ‘psychoses’ or current major affective disorder, were clinically assessed before completing computerized tasks of decision-making and planning previously shown to be sensitive to frontal lobe dysfunction, and tests of spatial and pattern visual recognition memory previously shown to be sensitive to frontal lobe damage and temporal lobe damage respectively. The performance of the BPD patient group was compared with that of a non-clinical control group consisting of 42 subjects. Results. The performance of the BPD patients on the decision-making task was characterized by a pattern of delayed and maladaptive choices when choosing between competing actions, and by impulsive, disinhibited responding when gambling on the outcome of their decisions. BPD patients also showed impairments on the planning task. There was no evidence of impaired visual recognition memory. Additional analyses suggested only limited effects of current medication and history of previous substance use disorder. Conclusions. These findings suggest that BPD is associated with complex impairments in dissociable cognitive processes mediated by circuitry encompassing the frontal lobes. These impairments may mediate some of the behavioural changes evident in BPD. Further work is needed to examine the specificity of these findings.
A Beam Steering Based Hybrid Precoding for MU-MIMO mmWave Systems

We propose a hybrid precoding scheme for downlink multi-user multiple-input multiple-output (MU-MIMO) millimeter-wave (mmWave) systems. Firstly, the proposed precoder is designed by the beam steering condition and the zero-interference condition, which can be obtained with the information of angles of departure (AoDs) in frequency division duplex (FDD) systems. Then, the proposed precoder is decomposed into the radio frequency (RF) precoder and the baseband precoder without the loss of response. Also, array response vector selection algorithm is proposed to prevent the sum rate degradation in numerous users region. Simulation results show that the sum rate of the proposed hybrid precoder is higher than those of the block diagonalization (BD) based schemes in the region of more than 5 users and approaches the sum rate of the beam steering scheme without MU interference as the number of base station (BS) antennas increases.
Klippel–Feil syndrome and neuraxial anaesthesia

Klippel-Feil syndrome (KFS) is an uncommon congenital disorder characterised by fusion of two or more cervical vertebrae. The perioperative anaesthetic management in these patients is complicated by anatomical changes, which presupposes the presence of difficult airway and by presence of multiple associated congenital anomalies. Literature search for anaesthetic management of KFS patient showed paucity of reports employing neuraxial technique.
Scanning the Commons? Evidence on the Benefits to Startups Participating in Open Standards Development

This paper contributes large-sample evidence to an emerging discussion on open innovation and firm strategy. We ask why a startup should participate in an open standards community. We propose four ways that participation might increase a startup's chances of a liquidity event: gaining endorsement of the startup's technology standard, openly developing the startup's technology within the community (but not necessarily gaining endorsement), simply attending physical meetings of the community, and having startup members elected to leadership positions. Examination of venture-funded startups in the networking/data communications industry sectors reveals that those startups that participate in an open standards community (the Internet Engineering Task Force (IETF)) have a greater likelihood of an initial public offering or acquisition. The strongest effects are due to attendance, and conditional on high levels of attendance, holding leadership positions within the IETF. Surprisingly, standards endorsement is insignificant when controlling for simple physical attendance. These results are robust to instrumental variable methods and alternative coding of variables. In two-stage models we also find that prominent venture capitalists might help their portfolio companies by steering them to effective technology strategies, in this case active participation in the IETF, and not simply by lending status.
Alterations to locomotor navigation in a complex environment at 7 and 30 days following a concussion in an elite athlete

Primary objective: To compare the locomotor capacity during (1) unobstructed walking and (2) the circumvention of fixed obstacles with and without a simultaneous visual task in an elite athlete before and after a sports-related concussion. Research design: Case report. Methods and procedures: Gait analysis and clinical neuropsychological measures were taken pre- and at 7 and 30 days post-injury in an 18 year old male junior hockey player. The task consisted of walking along an unobstructed or obstructed path with or without a visual interference task. Measurements included dual tasks costs, response errors, maximal gait speed and minimal clearance with the obstacle. Main outcome and results: Although the athlete was symptom-free and neuropsychological test results returned to baseline relatively quickly, he showed continued errors in the interference task, abnormally small obstacle clearance distances and decreased maximal gait speed up to 30 days after the concussion. Conclusions: Concussion can result in persistent planning and attention deficits in ecologically valid, complex environments. This report suggests that functional assessment within an ecological context could be an innovative way to evaluate concussed athletes before sending them back to play, even in the absence of medically related symptoms or abnormal neuropsychological test results.
