区域城市先进制造业现状分析与发展策略研究

粤港澳大湾区先进制造业基地建设对于中国制造业转型升级战略调整具有重要示范意义。通过构建先进制造能力评价体系,并对粤港澳大湾区9市进行对比分析。研究发现9市整体上具有良好产业基础,但仍存在科技创新能力、产业结构优化等问题,且具有产业发展动力不足、核心技术和人才匮乏、发展氛围欠佳和行业标准缺失等瓶颈。故此,基于生命周期理论度量9市先进制造业所处阶段,按照不同发展阶段提出产业协同、技术创新、产业融合和基础发展模式,从政府、企业和高校三方面提出应重视科研创新、产业结构优化、高新技术等问题解决的发展建议。

Biomechanical pole and leg characteristics during uphill diagonal roller skiing

Diagonal skiing as a major classical technique has hardly been investigated over the last two decades, although technique and racing velocities have developed substantially. The aims of the present study were to 1) analyse pole and leg kinetics and kinematics during submaximal uphill diagonal roller skiing and 2) identify biomechanical factors related to performance. Twelve elite skiers performed a time to exhaustion (performance) test on a treadmill. Joint kinematics and pole/plantar forces were recorded separately during diagonal roller skiing (9°; 11 km/h). Performance was correlated to cycle length (r = 0.77; P < 0.05), relative leg swing (r = 0.71), and gliding time (r = 0.74), hip flexion range of motion (ROM) during swing (r = 0.73) and knee extension ROM during gliding (r = 0.71). Push-off demonstrated performance correlations for impulse of leg force (r = 0.84), relative duration (r = ? 0.76) and knee flexion (r = 0.73) and extension ROM (r = 0.74). Relative time to peak pole force was associated with performance (r = 0.73). In summary, diagonal roller skiing performance was linked to 1) longer cycle length, 2) greater impulse of force during a shorter push-off with larger flexion/extension ROMs in leg joints, 3) longer leg swing, and 4) later peak pole force, demonstrating the major key characteristics to be emphasised in training.     

Deflection analysis of reinforced concrete beams strengthened with carbon fibre reinforced polymer under long-term load action

This paper presents the results of an experimental research on reinforced concrete beams strengthened with an external carbon fibre reinforced polymer(CFRP) layer under long-term load action that lasted for 330 d.We describe the characteristics of deflection development of the beams strengthened with different additional anchorages of the external carbon fibre composite layer during the period of interest.The conducted experiments showed that the additional anchorage influences the slip of the external layer with respect to the strengthened element.Thus,concrete and carbon fibre composite interface stiffness decreases with a long-term load action.Therefore,the proposed method of analysis based on the built-up-bars theory can be used to estimate concrete and carbon fibre composite interface stiffness in the case of long-term load.

在自制的碳纤维电极上,研究了碳纤维电极性能和对氯苯酚(p-CP)的电化学行为,考察了扫速、pH值以及浓度对p-CP在碳纤维电极上电化学行为的影响,实验结果表明p-CP在碳纤维电极上有灵敏的电化学响应,其电极氧化还原行为受吸附过程控制,p-CP在1 mol.L-1硫酸底液中,其氧化峰电流与对氯苯酚浓度在5×10-5～10-3mol.L-1范围内呈良好的线性关系(R2=9981),检出限为1×10-6mol.L-1,相对标准偏差为3.3%(n=10)。     

Childhood history of abuse and child abuse potential: The role of parent's gender and timing of childhood abuse

It has been suggested that being physically abused leads to someone becoming a perpetrator of abuse which could be associated to parents’ gender, timing of the physical abuse and specific socio-demographic variables. This study aims to investigate the role the parents’ gender, timing of childhood abuse and socio-demographic variables on the relationship between parents’ history of childhood physical abuse and current risk for children. The sample consisted of 920 parents (414 fathers, 506 mothers) from the Portuguese National Representative Study of Psychosocial Context of Child Abuse and Neglect who completed the Childhood History Questionnaire and the Child Abuse Potential Inventory. The results showed that fathers had lower current potential risk of becoming physical abuse perpetrators with their children than mothers although they did not differed in their physical victimization history. Moreover, the risk was higher in parents (both genders) with continuous history of victimization than in parents without victimization. Prediction models showed that for fathers and mothers separately similar socio-demographic variables (family income, number of children at home, employment status and marital status) predicted the potential risk of becoming physical abuses perpetrators. Nevertheless, the timing of victimization was different for fathers (before 13 years old) and mothers (after 13 years old). Then our study targets specific variables (timing of physical abuse, parents’ gender and specific socio-demographic variables), which may enable professionals to select groups of parents at greater need of participating in abuse prevention programs.     

Making sense of carbon footprints: how carbon literacy and quantitative literacy affects information gathering and decision-making

Abstract

Popular media often reports on the carbon footprint of certain activities, items or people. We were curious to explore how people make sense of these news pieces, and specifically, whether and how carbon literacy (CL) and quantitative literacy (QL) influences their reasoning. We interviewed and surveyed students of various backgrounds using simulated news pieces of three carbon footprints: that of Facebook, that of the US dairy industry, and that of the US chocolate industry. We found that being highly carbon or quantitatively literate influenced participants’ reaction – but only while they were gathering information about the prompts. The effect of literacies disappeared when they were asked to decide whether the carbon footprint was worrisome or which they would tackle first as a policy-maker. We describe and categorize the strategies students used to make sense of carbon footprints, and link the frequency of using particular strategies to their carbon and quantitative literacy. Implications for future research and environmental education are discussed.
