James Bessen, Learning by Doing: the Real Connection between Innovation, Wages, and Wealth

Abstract. Across most industries, workers feel the effects of automation.  Does innovation permanently replace workers or are they temporarily displaced within firms and labor markers?  James Bessen’s book Learning by Doing combines theory and economic history to illustrate and inform readers and managers alike concerning modern labor markets.Keywords. Wages, Wealth, Innovation.JEL. E21, E24, J30, O10, O30

Insight into the function of the obturator internus muscle in humans: observations with development and validation of an electromyography recording technique

There are no direct recordings of obturator internus muscle activity in humans because of difficult access for electromyography (EMG) electrodes. Functions attributed to this muscle are based on speculation and include hip external rotation/abduction, and a role in stabilization as an "adjustable ligament" of the hip. Here we present (1) a technique to insert intramuscular EMG electrodes into obturator internus plus (2) the results of an investigation of obturator internus activity relative to that of nearby hip muscles during voluntary hip efforts in two hip positions and a weight-bearing task. Fine-wire electrodes were inserted with ultrasound guidance into obturator internus, gluteus maximus, piriformis and quadratus femoris in ten participants. Participants performed ramped and maximal isometric hip efforts (open kinetic chain) into flexion/extension, abduction/adduction, and internal/external rotation, and hip rotation to end range in standing. Analysis of the relationship between activity of the obturator internus and the other hip muscles provided evidence of limited contamination of the recordings with crosstalk. Obturator internus EMG amplitude was greatest during hip extension, then external rotation then abduction, with minimal to no activation in other directions. Obturator internus EMG was more commonly the first muscle active during abduction and external rotation than other muscles. This study describes a viable and valid technique to record obturator internus EMG and provides the first evidence of its activation during simple functions. The observation of specificity of activation to certain force directions questions the hypothesis of a general role in hip stabilisation regardless of force direction

Protein regulation: Tag wrestling with relatives of ubiquitin

AbstractUbiquitin modification is a well established way of regulating protein levels and activities. Modification by related ubiquitin-like proteins is turning out to have a diverse range of interesting cellular functions

Designing an online resource for people with low back pain: health-care provider perspectives

People with low back pain (LBP) seek education and information from the Internet. Existing LBP websites are often of poor quality, and disparities have been identified between patient and health-care provider evaluations of LBP websites. This study aimed to identify health-care provider perspectives on desirable content for a proposed LBP website and how this information should be presented. It complements an earlier study of LBP patient (consumer) perspectives. A qualitative descriptive study, encompassing focus groups and telephone interviews, was conducted with 42 health-care professionals practising in the LBP field. Four categories of information were identified: explaining LBP; treatment and management options; myth-busting information; and communication with health-care professionals. Presentation preferences included: use of visual media; interactivity; and useability and readability. Comparison with the consumer study identified differences with regard to: depth and breadth of diagnostic and treatment information; provision of lay person experiences and stories; and capacity for consumer-to-consumer interaction online. Views of both consumers and health-care providers are critical when developing an online LBP resource. Failure to address the needs of both stakeholder groups diminishes the potential of the resource to improve consumer outcomes

Motor Adaptations to Pain during a Bilateral Plantarflexion Task: Does the Cost of Using the Non-Painful Limb Matter?

During a force-matched bilateral task, when pain is induced in one limb, a shift of load to the non-painful leg is classically observed. This study aimed to test the hypothesis that this adaptation to pain depends on the mechanical efficiency of the non-painful leg. We studied a bilateral plantarflexion task that allowed flexibility in the relative force produced with each leg, but constrained the sum of forces from both legs to match a target. We manipulated the mechanical efficiency of the non-painful leg by imposing scaling factors: 1, 0.75, or 0.25 to decrease mechanical efficiency (Decreased efficiency experiment: 18 participants); and 1, 1.33 or 4 to increase mechanical efficiency (Increased efficiency experiment: 17 participants). Participants performed multiple sets of three submaximal bilateral isometric plantarflexions with each scaling factor during two conditions (Baseline and Pain). Pain was induced by injection of hypertonic saline into the soleus. Force was equally distributed between legs during the Baseline contractions (laterality index was close to 1; Decreased efficiency experiment: 1.16±0.33; Increased efficiency experiment: 1.11±0.32), with no significant effect of Scaling factor. The laterality index was affected by Pain such that the painful leg contributed less than the non-painful leg to the total force (Decreased efficiency experiment: 0.90±0.41, P<0.001; Increased efficiency experiment: 0.75±0.32, P<0.001), regardless of the efficiency (scaling factor) of the non-painful leg. When compared to the force produced during Baseline of the corresponding scaling condition, a decrease in force produced by the painful leg was observed for all conditions, except for scaling 0.25. This decrease in force was correlated with a decrease in drive to the soleus muscle. These data highlight that regardless of the overall mechanical cost, the nervous system appears to prefer to alter force sharing between limbs such that force produced by the painful leg is reduced relative to the non-painful leg

Design of programs to train pelvic floor muscles in men with urinary dysfunction: systematic review

Pelvic floor muscle training (PFMT) is a first line conservative treatment for men with urinary dysfunction, but reports of its efficacy are variable. This study aimed to systematically review the content of PFMT programs used for urinary dysfunction in men.Electronic databases (PubMed, CINAHL, EMBASE, Cochrane, PEDro) were searched for studies that used PFMT in the treatment of adult men with urinary dysfunction. Details of PFMT treatment sessions and home exercise protocols were extracted. Criteria specific to PFMT were developed, based on the Consensus on Exercise Reporting Template, and applied to all studies to measure the comprehensiveness of the PFMT description in the manuscript.Results from the 108 included studies indicate substantial heterogeneity in both the content of PFMT and the quality of reporting of the components of the exercise regimes. There was notable disparity in the muscles targeted by the interventions (and few focused on urethral control despite the use in management of urinary conditions) and the intensity of the programs (eg, 18-240 contractions per day). Most studies were missing key details of description of the PFMT programs (eg, the position in which the pelvic floor muscle [PFM] contraction was taught and how it was assessed, methods used to ensure exercise adherence).Variation in content of PFMT programs is likely to contribute to variation in the reported efficacy for management of urinary dysfunction in men, and unclear description of the details of the evaluated programs makes it difficult to identify the effective/ineffective components.
