Community peer support among individuals living with spinal cord injury

Peer support is widely assumed to help individuals with spinal cord injury (SCI) adjust, yet the evidence is mixed. We propose that peer support may be more likely to promote adjustment when informal support is lacking. To test this hypothesis, 135 individuals living with SCI receiving peer support (46.7% female; Mage = 42.36, SD = 14.83) completed an online survey assessing aspects of and satisfaction with the peer support and family/friend support that they were receiving as well as measures of adjustment. Although those reporting receiving more peer support were not any better adjusted than those reporting less, individuals who were more satisfied with the peer support they received reported better adjustment. Moreover, the relation of satisfaction with peer support with depressive symptoms was dependent on the level of family/friend support. These findings suggest that peer support is most effective among those lacking support from family and friends.
Nature, timing and magnitude of buried Late Cretaceous magmatism on the central West Iberian Margin

The magma‐poor West Iberian Margin (WIM), as part of the Peri‐Atlantic alkaline province, records multiple evidence for intra‐plate post‐rift magmatism. Based on high‐resolution multichannel seismic data, this work discusses the presence of large volcanic and intrusive features in the Estremadura Spur, providing evidence for important magmatic activity during the drifting of the continental margin. Our observations reveal distinct voluminous fissure‐fed effusive sequences and the details of the 2800 m‐high Fontanelas compound volcano, including its external and internal architecture, secondary vents and associated lava flows, all of which were probably extruded at intermediate water depths. Numerous and morphologically diverse sills and sill complexes are also described, attesting to the presence of a Late Cretaceous shallow magmatic plumbing system in the area. Magmatism in this region is interpreted as having occurred during two main pulses and types of activity: (1) Coniacian to lower Campanian(? ) age, characterised by fissural and fault‐controlled volcanism, which mostly extruded massive lobate/sheet lava flows; and (2) a second voluminous intrusive and extrusive event of mid to late Campanian age, which includes the intrusion of the Estremadura Spur laccolith and the prominent Fontanelas compound volcano with associated dendritic lava flows. The inferred volumes of the first fissure‐fed effusive event suggest a large eruption magnitude, comparable to some of the largest historical effusive eruptions. The second magmatic pulse led to the emplacement of discrete clusters of sills and sill complexes, as well as the construction of the ca. 2.8‐km‐high Fontanelas volcano, suggesting a syn‐rift structural inheritance that controlled the location of the Estremadura Spur Intrusion and the Fontanelas volcanic area. Altogether, a total volume of rock exceeding 1.452 km3 is estimated to have been emplaced or extruded in this region in a relatively short period, attesting to the prominence of the magmatism in this sector of the WIM.
The Therapeutic Potential of Saw Palmetto Extract in Urological Disorders

Saw palmetto extract (SPE) has been widely used as a therapeutic remedy for urinary dysfunction in western countries. Furthermore, as an herb drug, it can be used as an alternative therapy for benign prostatic hyperplasia (BPH) due to its safety and minimum adverse effects. Reportedly, SPE improves the urinary symptoms, which mainly depend on anti-androgenic effects and effects on autonomic receptors in the lower urinary tract. However, the mechanisms of action responsible for the therapeutic roles of SPE have not been fully elucidated. Relevant studies indicate that SPE has some positive effects on the treatment of urological diseases in animals, and clinical trials are ongoing. In this review, we summarize the pharmacological properties and discuss the possible therapeutic mechanisms of SPE in urological diseases, including anti-androgenic effects, effects on autonomic receptors in the lower urinary tract, anti-inflammatory activity, anti-proliferative and pro-apoptotic effects, and highlight a potential therapeutic approach in the clinical treatment of patients with BPH, prostate cancer, chronic prostatitis (CP) and erectile dysfunction (ED).
Vaginal birth after previous caesarean section in women at Al-Wahda hospital Derna, Libya

Background: Vaginal birth after caesarean section is one strategy that has been developed to decrease the rate of caesarean section.Methods: The prospective observational study was carried out over a period of 01 January 2017 to 31 December 2018 years. VBAC was routinely offered at Al-Wahda hospital Derna to women fulfilling the criteria for trial of scar, according to the hospital protocol.Results: A total of 5018 deliveries took place in the study duration, there were 1039 (20.7%) had previous one caesarean section, out of which 319 (30.7%) were the number of underwent repeat caesarean section and 720 (69.3%) were the number of VBAC. The indications for emergency repeat caesarean section at Al-Wahda hospital was (29.3%) malpresentation, (24.45%) FD, (13.47) postdate, (11.59) obstracted lab and abruptiopl (5.95%). Anemia and difficult intubation were observed in repeated caesarean section.Conclusions: This study concluded that there is a high chance of success in a trial of labor. These findings might help clinicians and women in the decision-making for the mode of delivery when it comes to pregnancy with a previous caesarean section. Women are explained about the option of trial of scar and told about the risk associated with a repeat CS, so many CSs can be avoided.
Multilevel signaling for increasing the reach of 10 Gb/s lightwave systems

Polybinary, optical amplitude modulated phase shift keying (AM-PSK) polybinary, M-ary amplitude shift keying (ASK), and polyquaternary signaling schemes operating at 10 Gb/s are investigated in 1550-nm lightwave systems operating over standard, single-mode fiber. The premise for exploring these signal types is that they concentrate power at frequencies closer to the optical carrier where phase distortion of the optical field from chromatic dispersion is less severe. Issues such as modulator chirp, optimal level spacing in a 4-ary ASK signal, and phase modulated to amplitude modulated (PM-AM) noise conversion from a nonzero laser linewidth are studied. It is found that higher order polybinary signals do not offer an improvement in dispersion tolerance over a duobinary signal. 4-ary ASK is demonstrated to increase the dispersion-limited distance to 225 km experimentally and 350 km through simulation, but at the expense of a /spl sim/8 dB degradation in receiver sensitivity due to the increased number of levels and the signal dependence of signal-spontaneous beat noise. Furthermore, the linewidth requirement for a 4-ary ASK signal is less than 1 MHz in order to minimize the impact of PM-AM relative intensity noise (RIN) when transmitting over 200-300 km.
A Comparative Study of Design Base Shear for RC Buildings in Selected Seismic Design Codes

Modern seismic building design codes tend to converge on issues of design methodology and the state-of-the-art. However, significant differences exist in basic provisions of various codes. This paper compares important provisions related to the seismic design of RC buildings in some of the major national seismic building codes viz. ASCE 7, Eurocode 8, NZS 1170.5, and IS 1893. Code provisions regarding the specification of hazard, site classification, design response spectrum, ductility classification, response reduction factors, and minimum design base shear are compared and their cumulative effect on design base shear is studied. The objective component of overstrength contributed by the material and load factors is considered to normalize the design base shear. It is observed that every code has merit over the other codes in some aspect. The presented discussion highlights the major areas of differences which need attention in the process of harmonization of different codes of the world.

Toward an Organizing Approach to Teamwork

Team researchers in the field of organizational behavior (OB) seem to be increasingly aware of the need to embrace the organizing nature of teams. In this article, we outline the limitations of the prevailing static collectivist explanations in team research and suggest how an increased emphasis on a microdynamics-oriented approach that takes into account the essentially relational and organizing nature of teams can provide new insights to our understanding of teamwork. We argue that a multilevel, multi-theoretical, and multi-period framework may help enhance our understanding of teams. To show the advancements of the field in this sense, we review the OB literature on teams and highlight exemplars of research that have started to emphasize the microdynamic nature of teams consistent with this general framework, and their contributions to our understanding of team phenomena. We

This study focuses on the relationship between the design of the management accounting system, management style and the effects on organisational performance. This paper analyses the links between these variables based on a contingency approach. It contributes to the existing literature by providing additional evidence on the relationships between these variables within the public healthcare sector. The study distinguishes between innovative vs. traditional management accounting system designs and proactive vs. reactive management style. Data is collected from CEOs in public hospitals. A two-fold analysis involving interviews and a questionnaire was adopted thus enabling a systematic and comprehensive analysis.
Report: the use of Life Cycle Inventory tools to support an integrated approach to solid waste management

Solid waste management needs to be environmentally sustainable to reduce overall environmental burdens. It also needs to be economically sustainable to be affordable for all sectors of the community served. Integrated waste management (IWM) takes an overall approach to this, involves the use of a range of different treatment options and deals with the entire waste stream. The tool of Life Cycle Inventory (the goal definition and inventory stages of a Life Cycle Assessment) can successfully be applied to integrated waste management systems to assess their environmental burdens. Life Cycle Inventory (LCI) tools for solid waste management have been available for some time. Several models have been developed and applied to both theoretical and actual waste management strategies. This report reviews a case study where a Life Cycle Inventory model was applied in the development of an integrated approach to waste management.
Numerical Modeling of Tidal Circulation in Harbors

In this study a numerical model has been developed that can be used to predict the two-dimensional tide-induced velocity fields in harbors and estuaries. The model is particularly suited to basins having a narrow entrance where, on the incoming tide, the divergence of the velocity field associated with the jet inlet gives rise to the generation of vorticity. The time-dependent nonlinear equations of motion are formulated to include the effects of bottom roughness, wind action, the earth's rotation, and a simplified version of the turbulent transfer of momentum. These equations are expressed in an alternating-direction implicit finite difference form and are solved by Gaussian elimination. The numerical model has been checked by making comparisons between the computed velocity fields and experimentally measured velocities and path lines for two hydraulic model studies involving various rectangular harbors and a circular reservoir.
Factors Constraining Quality Service Provision in the BRT Project in Dar es Salaam, Tanzania

This study examined factors constraining quality of service provided by DART by focusing on the customer satisfaction criteria of SERVIQUAL model notably tangibility, responsiveness, reliability, assurance and empathy. A mixed approach method was used, where by data collection was undertaken using interviews, focus group discussion, and analysis of relevant docu-ments as well as indirect observations techniques. Findings show that constraints to tangibility were related to inadequacy in the number of BRT buses, ineffective ticketing procedures, communication infrastructures and BRT infrastructure coupled with interference of BRT routes. Related to responsiveness, over loading of passengers, poor communication strategy and skills and lack of customer care were cited. With regard to reliability, long waiting time, seasonal floods and negative customer behaviours were revealed. While pickpocketing, fear of contracting diseases and lack of customer care and communication skills were related to assurance, absence of first aid services, lack of customer care and communications skills were constraints to empathy. These findings provide insights to the policy makers in public transport systems as well as the transportation sector as a whole for the pur-pose of improving improve the DART services.
Industrial branding using digital media : case: The Switch

The shift from traditional marketing channels to the digital channels has been rapid which has generated new challenges and opportunities for business-to-business (B2B) communication and brand building processes. In general, studies of B2B branding are scarce, since branding has been approached as a business-to-consumer (B2C) function. In future B2B branding and brand management may well become a critical success factor in the market, since competition brought by globalization and market liberalization assisted by the internet revolution. This research will combine these previously presented themes; B2B branding and digitalization, and hence try to understand the phenomena of industrial branding in the digital age. The main objective of this study is to enhance understanding of how to build an international industrial brand with digital media. The research is descriptive and explorative in nature and conducted from the company management perspective. The phenomenon is approached through one case study concerning a Finnish-based growth company called The Switch. The Switch is also a great example for other young Finnish companies who need to be encouraged to think big and pay attention to marketing and communication as a strategic asset. The findings of this study suggest that it is beneficial to build an industrial brand in the digital environment in a consistent manner, as a strategic asset by integrating genuinely different operational functions. Branding should be market driven but diligently consider the company’s internal capabilities and affairs. To keep the brand relevant and active, branding should be seen as an ongoing process requiring continuous adjustment of the brand through monitoring of the environment and reacting to weak signals. In the age of digitalization, branding should include planning, coordination and participation rather than controlling. Branding in the digital age requires stories to be told, not marketing messages to be sent.
Enhanced aeroelastic energy harvesting with a beam stiffener

In this article, we propose an easy but quite effective method to significantly enhance the power generation capability of an aeroelastic energy harvester. The method is to attach a beam stiffener to the substrate of the harvester, which works as an electromechanical coupling magnifier. It is shown to be effective for all three considered types of harvesters based on galloping, vortex-induced vibration and flutter, leading to a superior performance over the conventional designs without the beam stiffener, with dozens of times the increase in power and an almost 100% increase in the power extraction efficiency yet with comparable or even smaller transverse displacement. Choice guidelines of optimal types of energy harvesters are also suggested based on the given wind situations where the electronic device is located.
Entrepreneurship in electrical engineering education

The program in entrepreneurship education offered by the Electrical Engineering Department at the University of Nevada, Reno (UNR) has as one of its courses a senior-level undergraduate course which takes a hands-on approach to teaching electrical engineering students the concepts of innovation and entrepreneurship. The basic goal is for students to experience the product development process as well as how to start a new company. The students are separated into groups and form companies known as E-teams. They generate a few product ideas, evaluate them and choose one to explore, develop the product idea into a functional prototype, and finally perform market/financial analysis to determine if the product could sustain an actual business. Once they have completed this process, the E-teams present all of their findings at a final presentation to faculty members and guests from the private industry sector. The idea is for the E-teams to experience an actual start-up process and attempt to take it to the point of soliciting financial support. While they negotiate the product development process, the E-teams are given a wide variety of lectures that provide them with valuable insight into being both effective engineers and entrepreneurs. The class fits into the engineering curriculum by offering students a capstone course, i.e. one that ties their entire college education together. This class has been extended to include MBA majors from the College of Business at UNR. This paper describes the format, content and results of teaching the class.
Design Methodology for Transformers Including Integrated and Center-tapped Structures for LLC Resonant Converters

A design methodology for transformers including integrated and center-tapped structures for LLC resonant converters is proposed. In the LLC resonant converter, the resonant inductor in the primary side can be merged in the transformer as a leakage inductance. And, the absence of the secondary filter inductor creates low voltage stress on the secondary rectifiers and is cost-effective. A center-tapped structure of the transformer secondary side is widely used in commercial applications because of its higher efficiency and lower cost than full-bridge structures in the rectifying stages. However, this transformer structure has problems of resonance unbalance and transformer inefficiency caused by leakage inductance imbalance in the secondary side and the position of the air-gap in the transformer, respectively. In this paper, gain curves and soft-switching conditions are derived by first harmonic approximation (FHA) and operating circuit simulation. In addition, the effects of the transformer including integrated and center-tapped structures are analyzed by new FHA models and simulations to obtain an optimal design. Finally, the effects of the air-gap position are analyzed by an electromagnetic field simulator. The proposed analysis and design are verified by experimental results with a 385W LLC resonant converter.
Effects of Surface Preparation on the Corrosion Behavior of Mild Steel

Surface preparation of engineering materials is necessary for preventing corrosion and subsequent failure of materials in service. There are different methods of surface preparations that can affect engineering materials in different ways. This study investigated the effect of surface preparation on the corrosion behavior of zinc sprayed and unsprayed mild steel. Quantitative analysis and potentiodynamic polarization techniques were used to evaluate the immersed samples of different surface preparations. The results indicated that the least corrosion rate was observed for the uncoated sample prepared with CC1200 grit paper at 0.041 mpy and successive samples in the order of CC220 grit paper at 0.047 mpy < P60 grit paper at 0.052 mpy < filing at 0.064 mpy and grinding at 0.074 mpy after 42-days of immersion. The prepared samples that were further coated with zinc spray demonstrated a similar trend. The sample prepared with CC1200 grit paper and further coated with zinc spray exhibited the lowest corrosion rate of 1.35 x 10-9 mpy. Potentiodynamic polarization results further suggested that the same behavior was observed in the quantitative analysis.
